Information Communication Technology in Agriculture Essay

Data Communication Technology in Agriculture - Essay Example Notwithstanding utilizing current existing innovation creation is coming out poor, which implies there are some basic factors that are influencing it. In this paper different methodologies will be taken to sift through the key purposes of this issue. Ranchers will be met legitimately or in a roundabout way so as to get their perspectives about whether they are accepting appropriate data and information or not; or the data given to them is adequate and reasonable or not. After appropriate review Information Communication Technology (ICT) will be utilized to redress them. This paper generally focuses on various extents of ICT in the field of farming. Urbanization which straightforwardly influences the horticultural land. Before urbanization appropriate information ashore the board is important. Assume one land that can suit 100 people sufficiently however because of inappropriate land the executives just 50 people groups are getting set. It results into increment in urban zone superfluously. This issue can be settled utilizing data innovation where, individuals' propensities, tastes and ways of life are contemplated and as indicated by that ideal local location can be characterized. Climatic changes like flood dry season, climate changes likewise have impacts on foods1. The present innovation that can be utilized for advanced factual figuring so as to get thought of climatic change and dependent on that, means are taken. The most significant factor is missing ... The most significant factor is missing of appropriate information among people in general in regards to the better utilizing of assets. Here Information Communication Technology (ICT) assumes one essential job. ICT is the best apparatus for sharing information among ranchers. Setting up country system will upgrade ranchers' thought trading capacity. Aside from that utilizing remote homestead counseling framework through camera and remote, sufficient data can be conveyed. Research Questions Research proposition begins with explore question or theory. For this examination investigate questions are: 1. What are the fundamental issues that horticulture industry is confronting today 2. Will Information Communication Technology (ICT) work better for these cases 3.

Nuns, fret not!

Nuns, fret not! Im a little nervous right now, because I have my first major exam this week (Wednesday, in chemistry), but its my favorite class (and not only because my TA is Canadian and says molar mahss) so Im less worried about it than I am about my first major paper due the day after both the exam and the season premiere of Lost. Theres no guarantee that Ill be able to concentrate that night. Instead of concentrating this weekend, I blew off steam by going on retreat with my hall (3rd East) to New Hampshire! Not all of us can go on fantasy pirate cruise ships, so we all chipped in $35 and rented cars and a cabin (apparently, MIT students can rent cars, even if theyre under 21). We danced, watched movies, and almost fell off a giant mountain. Zozer 07 smashed a fly with a spatula. What better way to get to know your hall? So a lot of you have commented about coming from mediocre schools without any particular science/math focus, and not having any research opportunities. A year ago, my comment wouldve read Whats the science olympiad? There are actually schools that focus on science and math? Can I make a baking soda volcano and submit that as research? But now? Now, my comment says Chill out, man. Also, Mr. Neha, we should throw out these bananas. Theyre a little too ripe. Its an understandable contrast, since Im writing the blog now and not applying but two of my closest friends here came from a high school that offered only 4 AP classes. My high scool was just a regular public high school, not private or magnet our biggest pride was our football team, not our academic decathalon. It just happens that way some areas are privy to more opportunities than others, and the admissions office will take that into account. I, too, had no science olympiad program readily available at my high school. I didnt have any AMC scores to submit, and I was just as terrified to submit my application with that seemingly obvious hole in the middle. So I know how easy it is to dwell on your weaknesses, and Im not saying that NOT having AIME scores will get you in, but it wont make you or break you. Its not your responsibility to cover all the weaknesses that come with your environment, because its not your fault if you cant find people who are just as excited about microbiology as you are but its also good to show initiative and look for ways around them, if you can. So look for opportunities offered outside of your school that you can take on yourself; classes offered at local colleges or online are a good place to start. And there are plenty of research opportunities out there totally unrelated to where you come from the summer after my junior year, I spent five weeks scuba diving and measuring the abundance of Diadema antillarum, the spiny sea urchin, inside and outside of the marine protected areas of South Caicos through the School for Field Studies. I was one of three high school students there, and the knowledge and maturity I gained from that experience is something Id never have found at my high school it put me in a place where I was utterly uncomfortable and forced me to adapt to my surroundings. But theres no set formula to one application MIT is looking for more than that. The important thing to remember when youre applying, whether you have too much to write about or nothing at all, is that youre being evaluated on you, as a person, and whether you as a person fits at MIT, not whether or not you come from a magnet school or are homeschooled. Because after this whole thing is over, youll no longer be a part of that mediocre school, but youll very much still be you as a person. The only difference is youll be a freshman in college wondering why your bananas, too, are so very ripe. It happens to the best of us. Post Tagged #Next House

Essay Abortion - 1041 Words

Abortion is never an easy decision, in fact its one of America’s most controversial issues in today’s reality, but women have none the less been making that choice for thousands of years. Studies show that about 43% of American women will have one or more abortions during their lifetime, and womens centers and hospitals perform more than a million abortions on an annual basis. Women have many reasons for not wanting to be pregnant including age, marital status, economic status, and the circumstances of their pregnancy, and thus seek out an abortion. Although many citizens view abortion as an immoral act of brutality and strongly contest its usage, others believe the choice belongs solely to the mother and the mother alone.

(Durrett 126) Another key issue in regards to abortion is whether or not a raped woman should continue and bare the child or chose to abort the fetus. Pro-lifers believe that the unborn child has the right to live and even if the woman faces an unwanted pregnancy, she should carry the child to term and make the best of her situation with the help available to her and her family. They further believe an abortion only traumatizes the raped woman further, when she realizes she has killed her own child. Through an abortion, the mother becomes the aggressor and ultimately murders a future child. (Brennan 26) Under pro choice views, during rape the woman does not give consent to participate in sexual activities and therefore can not be held liable for the pregnancy forced onto her by the criminal acts of injustice done to her. In this circumstance, abortion would not be considered murder and by doing so the victim would be able to retain a normal life once again. Now, if women are forced to carry unwant ed pregnancies to term, the result would be an unwanted child. (Sloan 27-34) These children epitomize societys most awful cases, often neglected, unloved, brutalized, and more often than not, simply abandoned along deserted ally ways, or in dumpsters or even on the sides of freeways.

CLAUSER and lnstitut de Biochimie, Universit6 de Paris-Sud, Orsay (Received April 9/July 17, 1973) Extracts prepared from rat diaphragms incubated with or without theophylline and/or epinephrine have been tested for their total cyclic AMP content and for their ability to bind exogenously added cyclic [â€Å"]AMP. Less cyclic [3H]AMP can be bound inthe extracts after theophylline and/or epinephrine treatment indicating that the rise in cyclic AMP level was accompanied by a n increase in the quantity of cyclic AMP bound intracellularly to the cyclic AMP-dependent protein kinases. Maximum cyclic AMP binding capacities, as measured by total cyclic AMP exchanges, were however identical in all cases. Accurate estimations of intracellular binding of cyclic AMP have been correlated with the level of cyclic AMP in the tissue : the reaction seems to obey simple saturation kinetics, a n apparent intracellular K d for cyclic AMP has been evaluated as 330 nM. The findings are consistent either with a real difference in the intracellular binding constant as compared to that measured in vitro (28 nM) or with the fact that the cyclic nucleotide in the cell may not all be available for the kinase protein receptors. They also suggest that the method described may prove useful for studying any possible intracellular control beyond the step of cyclic AMP synthesis. Regulation of cellular metabolism by adenosine 3†² :5†²-monophosphate (cyclic AMP) [I], its mediation through complex protein kinases [2,3] and the mechanism of the activation of these enzymes [4–61 have been well documented within the past years in the eukaryotic cell. Activation has been demonstrated to occur according to Equation (1) through a n interaction of cyclic AMP with the regulatory subunit (R) of the enzyme, leading to a dissociation of this subunit from the catalytic subunit (C) which is thus activated. RC cyclic AMP + R cyclic AMP C . (1) + + However completely satisfactory correlations between the levels of intracellular cyclic AMP and its ultimate metabolic effects have been in many cases difficult to obtain. Striking examples for this situation are to be found in the results of Craig et al. [7] in rat diaphragm, of Stull and Mayer [8] in rabbit skeletal muscle concerning the regulation of phosphorylase activation, of Schaeffer et al. [9] and Miller et al. [lo] concerning regulation of glycogen metabolism in adrenalectomized rats, and of Harbon and Clauser [Ill This work is dedicated to Professor E. Lederer for his 65 th anniversary. Abbreviations. Cyclic AMP; adenosine 3†²: 5†²-monophosphate. in the rat uterus stimulated by prostaglandin El or E,. I n all these cases, cyclic AMP levels may be elevated without eliciting the expected metabolic responses. Two hypotheses have been formulated to explain these obvious discrepancies, either a decrease in the activation of the enzymes mediating cyclic AMP action within the cell, or a compartmentalization of the intracellular nucleotide. Hence it seems necessary to measure directly the degree to which the first step of the activation sequence (Equation 1)reflects the apparent intracellular cyclic AMP concentrations. This might be achieved by establishing in intact cells or tissues, correlations between the levels of intracellular cyclic AMP under welldefined physiological conditions, the extent to which it is bound to the specific receptor protein and the extent to which the complex protein kinases are in the active state. Satisfactory correlations between cyclic AMP levels and protein kinase activation have been recently established in various tissues by Corbin et al. [I21 and Soderling et al. [13]. The present work was to investigate if correlations could also be obtained between intracellular cyclic AMP levels and the amounts of intracellular cyclic AMP bound to receptor protein (R cyclic AMP) in the surviving rat diaphragm incubated with or without theophylline and epinephrine. The results reported demonstrate that – E r J. Biochem. 40 (1973) u. 178 Intracellular Titration of Cyclic AMP-Receptor Protein Binding precise titrations of endogenous cyclic AMP bound versus cyclic AMP present in the intact tissue may be obtained. An apparent Kd value for the intracehlar cyclic AMP binding is observed which differs widely from the K d of the same binding established in vitro [14-161. This method may prove to be useful for studying the modification of cyclic AMP binding under conditions where the formation and breakdown of cyclic AMP does not seem to be affected. A preliminary report of these results has been presented [17]. MATERIALS AND METHODS Cylic AMP was obtained from P L Biochemicals Inc. , theophylline and Tris from Merck (Darmstadt), Na,ATP 4 H,O, L-epinephrine bitartrate from Calbiochem. Cellulose ester membrane filters (HA 0. 45 pm, 24 mm) were purchased from Millipore Corp. All reagents used were products of Prolabo (reagent grade). Cyclic [3H]AMP was a product of New England Nuclear Inc. , specific activity 24 Ci/ mmol. Animals were Wistar rats weighing about 200 to 300 g and fasted 24 h before the experiments. Tissue homogenizations were performed with an Ultra Turrax homogenizer. – The reaction mixture for the binding assay contained in a final volume of 250 p1, 20 mM TrisHC1 buffer pH 7. 5, 10 mM MgCI,, 6. 7 mM theophylline and cyclic [3H]AMP a t various concentrations as indicated. The reaction was initiated by the addition of a n aliquot of diaphragm extracts equivalent to 70- 150 pg protein. Method B. I n this case, cyclic [3H]AMPwas added to the homogenizing medium a t saturating concentrations up to 0. 2 p M a t 0 â€Å"C, centrifugation was carried out immediately and cyclic [3H]AMP bound measured directly on the extract. Cyclic [3H]AMP bound to the proteins, under either condition, was determined after different incubation times at 0 â€Å"C: the reaction mixtures were then diluted to 3 m l with cold buffer (20mM TrisHC1, 10mM MgCl,, pH 7. 5) and passed through cellulose acetate Millipore filters (0. 45 pm). The filters were washed with 25ml of the same buffer, dried and counted in i 0 ml scintillation fluid, in a Packard Tri-Carb liquid scintillation spectrometer. Results were expressed as pmol cyclic AMP bound/mg protein ; the concentration of endogenous unlabelled cyclic AMP has been always taken into account for the estimation of the specific activity of cyclic [3H]AMP present in the incubation medium. Incubation Procedures The animals were killed by decapitation. The diaphragms were rapidly removed, freed from connective tissue, cut to small pieces, pooled and divided into equal parts. 200-250 mg tissue were preincubated in 2. ml Krebs-Ringer-bicarbonate buffer pH 7. 4, gas phase (95O/, O,, 5O//, CO,) for 30 min a t 37 â€Å"C, in the absence or presence of 10 mM theophylline. Incubations were then performed in the absence or presence of epinephrine (5 pM) for varying periods of time. Extraction of the Tissue Standard Binding Assays for Cyclic A M P Two methods have been deviced to extract the tissue and estimate the binding of exogenous cyclic [3H]AMP to the extracted proteins, both slightly modified from the method defined by Walton and Garren [15]. Method A . The tissue was homogenized a t 0 â€Å"C in 3 ml of one of the following solutions: 20 mM TrisHCl buffer pH 7. or 20 mM sodium acetate pH 7. 5 or 4 mM EDTA pH 6. 0. Theophylline (10 mM) was always present in the various homogenizing media in order to minimize any degradation of cyclio AMP by phosphodiesterase present in diaphragm extracts. A first centrifugation was carried out for 5 min a t 3000 x g , followed by a second one a t 50000 x g for 30min. The supernatants will be referred to as Tris extract, acetate extract and EDTA extract. Assay for Cyclic-AMP Levels For cyclic AMP assay, the tissue was homogenized in 3 ml cold 7 trichloroacetic acid and centrifuged for 30 min a t 50000 xg. After addition of 0. 1 ml N HC1, the supernatants were extracted 7-8 times with twice their volume of cold ether and evaporated to dryness. Total levels of cyclic AMP in the tissue trichloroacetic acid extract were determined according to Gilman using a protein b a s e and the heatstable inhibitor prepared from rabbit skeletal muscle [161. I n some instances, cyclic AMP content was also evaluated in the Tris and acetate extracts. Proteins were precipitated by trichloroacetic acid and extracts processed as described above. Proteins in the extracts were determined according to Lowry et al. 18] using bovine serum albumin as a standard. RESULTS AXD DISCUSSION Total Cyclic-AMP Levels in Rat Diaphragm. Effects of Epinephrine and Theophylline In order to study the cyclic AMP binding capacity of rat diaphragm proteins and its possible rnodification under the influence of epinephrine, it seemed necessary to test the first effect of the catecholamine, viz. the rise in the tissue cyclic AMP lev el under our experimental conditions.

Theophylline alone (10 mM) had a stimulating effect, double; when both compounds were used together, the rise in cyclic AMP levels was 8- t o 9-fold, reaching 350pmol cyclic AMP/100 mg wet tissue. When cyclic AMP was assayed in either acetate or Tris extracts after deproteinization with trichloroacetic acid the values obtained were identical t o those found when the diaphragms were directly extracted with trichloroacetic acid ; hence almost none of the cyclic nucleotide in these extracts was associatcd with membrane-bound fractions (Table 2). Eur. J. Biochem. 0 (1973) Location of Cyclic AMP-Binding Fractions Table 3 shows the distribution of cyclic AMP binding activity in various fractions of three rat diaphragm homogenates measured by method A : in all cases more than goo/, of this activity was recovered in the 50000 x g supernatant, almost no cyclic AMP binding occurred in the pellets. Preincubation of the diaphragm with epinephrine did not modify the percentage distribution of the radioactive nucleotide between the supernatants and the pellets, hence subsequent experiments have been performed on the soluble extracts. On the other hand, in the case of epinephrine-treated diaphragms, less exogenous labelled cyclic AMP (about 50-60 °/0) was bound to the various fractions, indicating a decrease in the binding capacity of the extract as compared to the untreated diaphragm. Dilution by endogenous cyclic AMP cannot explain the effect of epinephrine, since allowance was made for this parameter (see Methods) ; the phenomenon was consistently reproducible and will be further substantiated and discussed below. The binding capacities of the various extracts for cyclic E3H]AMP have also been verified in the absence of any free endogenous cyclic AMP after removal of the latter by filtration through Sephadex G 50 (1x 37 cm) columns, previously equilibrated with 20 mM Tris-HC1 buffer, pH 7. 5 a t 4 â€Å"C. I n these experiments, the detail of which w l not be reported in i l the present manuscript, the effect of epinephrine was still observed, when binding was measured on the main protein peak emerging with the void volume of the columns.

Double-reciprocal plot, according to Klotz [25] Fig. 2. Cyclic-AMP-Concentration dependence of cyclic A M P binding in rat-diaphragm extracts (method B ) . Binding assays were carried out as described under method B. Various concentrations of cyclic [3H]AMP ranging from 12nM to 200 nM were added directly to the homogenizing medium for preparing extracts from epinephrine treated (A-A) and untreated (0-0) rat diaphragms. Aliquot,s of the extracts were filtered through Millipore filters, dried and counted. Double-reciprocal plot, according to Klotz [25] present paper were applied to these figures, the results were essentially identical to those obtained with the unfiltered extracts. Specificity. Kinetics and Concentration Dependence of Exogenous Cyclic-AMP Binding in the Extracts Specificity of cyclic AMP binding has been assessed by dilution experiments of cyclic [3H]AMP (100 nM) with unlabelled nucleotides (adenine, AMP, ATP, cyclic AMP) a t molar concentrations equalling up t o 100 times cyclic [3H]AMP concentrations. I n no case, except with unlabelled cyclic AMP, the amount of radioactive material bound to proteins by either method A or B was significantly reduced (the details of these experiments are not reported). When various concentrations of cyclic [3H]AMP were added to diaphragm extracts (after homogenization and centrifugation) and the binding reaction (method A) carried out for different incubation times at 0 â€Å"C (Fig. I), it appears that saturation was obtained at a concentration of 80 nM for the cyclic nucleotide which essentially coincides with previously published data [14-161 and that binding equilibrium was reached a t p H 7. 5 and 0 â€Å"C after less than 60 min incubation. It has also been verified that with the protein concentration used (70-150 pg in 250 pl) binding of cyclic AMP was directly proportional to the amount of added proteins. From a reciprocal plot of cyclic AMP binding versus cyclic AMP concentration (inset of Fig. I), an apparent Kd of 33 nM can be calculated. When similar experiments were performed by adding various concentrations of cyclic [3H]AMP into the homogenizing medium (method B) and using diaphragms which have been incubated in the presence and absence of epinephrine, the double-reciprocal plots of Fig. 2 were obtained. The apparent Kd values calculated with this method (45 nM) are in the same range as with method A. I n addition this figure shows that epinephrine treatment of the diaphragms does not modify this Kd but decreases the amount of exogenous cyclic AMP which can be bound to the extract proteins. By comparing exogenous cyclic AMP binding values obtained with methods A and B, it appears (Table 4) that when cyclic [3H]AMPwas added to the Eur. J. Biochem. 40 (1973) L. Do Khac, S. Harbon, and H.

Rat diaphragms were incubated with theophylline in the absence or presancc of 5 p M epinephrine. Extracts in Tris-HC1 were prepared as described under method A for subsequent binding of cyclic [3H]AMP (100 nM), 1 h, a t 0 â€Å"C. A second series of extracts were prepared in the same way but in the prescnce of 100 nM cyclic [3H]ABIP in the homogenizing medium (method R); binding of cyclic [3H]AMP was measured in a n aliquot immediately after centrifugation at 0 â€Å"C (about 1 h after the end of incubation).

This demonstrates that some additional binding of endogenous cyclic AMP occurred during the homogenization and fractionati on procedures, which tends to decrease the amount of unoccupied binding sites available for exogenous cyclic [3H]AMP. Hence method B has been currently used to measure exogenous cyclic AMP binding, since the values obtained with this method seem to reflect intracellular conditions more accurately. Fig. 3. Time course of cyclic [3H]AMP binding in extracts from rat diaphragms incubated in the absence or presence of theophylline orland epinephrine. Half rat diaphragms were preincubated in the absence (m, A ) or in the presence ( 0 , 0 ) of 10 m31 theophylline for 30 min at 37 â€Å"C. Epinephrine (5 pM) was added ( A , 0 )and incubation continued for 5min. Tissue was homogenized in 1. 5 ml Tris-HC1 buffer containing 200 nnf cyclic [3H]AMP and centrifuged at 5000xg for 10 min at 0 â€Å"C. Binding of cyclic [3H]AMP was measured in aliquots of the supernatant at the times indicated, through Millipore filtration, t = 0 corresponds to the onset of the extraction. Results are expressed as pmol cyclic AMP bound/ mg protein (without correction for cyclic AMP exchange) Effect of Theophylline and Epinephrine Treatment on the Binding of Exogenous Cyclic [3H]AMP by Diaphragm Extracts Fig. 3 shows the results of a typical experiment in which diaphragms have been incubated in the absence or presence of theophylline and epinephrine. Homogenization has been performed according to method B, the centrifugation time of the homogenate kept to a inimum (10 min), and the binding capacity for cyclic [3H]AMP determined a t different times. As may have been expected, this cyclic [3H]AMP binding (which measures the residual binding capacities of the extracts) was, in the course of the whole titration period, inversely related t o the amount of endogenous cyclic AMP present in the relevant ext racts (see Table 1). Hence the agents which increase the intracellular cyclic AMP level appear to decrease the amount of binding sites available for exogenous cyclic [3H]AMP, probably through an increase of endogenous cyclic AMP binding to the receptors. I n order to titrate endogenous binding of cyclic AMP accurately, experiments were designed to estiEm. J. Biochem. 40 (1973) mate the total binding capacities of the extracts through complete exchange of endogenously bound cyclic AMP with cyclic [3H]AMP, and also to estimate the actual amount of exchange occurring in the extracts between endogenous bound unlabelled cyclic AMP and exogenous cyclic [3H]AMP during the titration period. A precise knowledge of these two parameters is required for the determination of the binding sites occupied by endogenous cyclic AMP at the moment where the tissues are homogenized. Cyclic-AM P Exchange and Determination of Maximal Binding Capacities Total cyclic AMP exchange has been measured under the conditions defined by Wilchek et al. [19] for parotid gland and skeletal muscle : extracts from both treated and untreated diaphragms were f i s t incubated at 0 â€Å"C with cyclic [3H]AMP (100 nM) under binding conditions of method A and then allowed t o exchange with 1 pM unlabelled cyclic AMP at 20 â€Å"C in the presence of 100p. M ATP and 10mM MgCl,.

Exchange of bound cyclic [SHIAMP. Extracts were prepared from epinephrine-treated ( + o ) and untreated (0-0) rat diaphragms. Binding of cyclic [3H]AMP was carried out a t 0 â€Å"C in a volume of 2. 5 ml with 500 pg proteins, and 100 nM cyclic r3H]AMP in Tris-HC1 buffer, MgCl, and theophylline a t the concentrations described for the standard binding assay. After 1-h incubation, 1 pM unlabelled cyclic AMP and 100 pM ATP were added and the mixture allowed to stand at 20 °C. At the different times indicated in the figure, aliquots corresponding t o 50 pg protein were pipetted, rapidly diluted with 20 mM Tris-HC1 buffer, 2. 5 mM MgC1, p H 7 5 and filtered through Millipore filters. The filters . were washed with the same buffer, dried and counted. Results are expressed as pmol/mg protein 0 30 60 90 120 Time (rnin) 180 240 – Total binding capacities of the proteins could thus be measured by incubating the extracts first with 100 nM unlabelled cyclic AMP a t 0 â€Å"C and carrying on the exchange reaction in the presence of 1 pM cyclic I13H]AMP at 20 â€Å"C for 1-2 h ; the values obtained averaged 8. -9. 5 pmol cyclic [3H]AMP/mg soluble protein, both with epinephrine-treated and untreated diaphragms. These results were confirmed by direct assay of bound cyclic AMP: the extracts have been fully saturated with unlabelled 1pM cyclic AMP and filtered as described. After washing the Millipore filters, bound cyclic AMP was extracted by cold 7 O/, trichl oroacetic acid and the cyclic nucleotide was directly assayed according to Gilman [16]. The average value was 9. 8 f 0. 4 pmol cyclic AMP bound per mg protein, which is of the same order of magnitude as the amount of bound cyclic [3H]AMP calculated above. Previously published data are in close agreement with these values. Walton and GarFen [15] reported maximal binding capacities of 9. 8 pmol/mg protein for adrenal extracts, whereas Gilman [l6] found a total binding of 12pmol/mg protein in muscle extracts. The values for maximal cyclic AMP binding are very low as compared t o the total endogenous cyclic AMP present in the extract (46 pmol/mg protein with the theophylline-treated diaphragm and 170 pmol/mg protein with the epinephrine theophylline-treated diaphragm). It must be added that the binding proteins, saturated with cyclic AMP or not, were almost completely retained on the Millipore filters, and that endogenous cyclic AMP, not Fig. 5.

The extent t o which this â€Å"free† cyclic AMP may or not be bound to other proteins is presently not known. Cyclic-AMP Exchange under Binding Conditions The extent of cyclic AMP exchange under binding conditions (0 â€Å"C, 1 h, 100 nM cyclic AMP) must be controlled if corrections for simultaneous exchange have to be applied t o binding data: extracts of rat diaphragms treated with theophylline and theophylline epinephrine were first saturated with 1 O O n M unlabelled cyclic AMP (binding conditions) and then exchanged with 1 pM cyclic [3H]AMP but a t 0 â€Å"C. After 2 h, the temperature was raised to 20 â€Å"C and completion ofthe exchange measured after 1-2 h further incubation. Fig. 5 shows that a t 0 â€Å"C, within 1h incubation time, which are the conditions described above for the binding assay, about 200/, of total sites were exchangeable. Under these conditions, ATP and Mg ions slightly increase the exchange velocity.

Effects of Theophylline and Epinephrine Since total bindin g capacities of the receptor proteins in the extracts and the amount of exogenous cyclic [3H]AMP bound by these extracts after homogenization may be estimated, it appears possible to calculate endogenous cyclic AMP bound in the intact organs, correcting for a 2001, exchange during the titration period. Table 5 summarizes the results of a series of experiments where diaphragms have been incubated under conditions which modify endogenous levels of cyclic AMP :in every case, half of the diaphragm was extracted with cold trichloroacetic acid (see Methods) for the assay of intracellular cyclic AMP levels: the second half was extracted according to method B for the estimation of exogenous cyclic [3H]AMP binding and of total cyclic AMP binding capacities. The endogenous cyclic AMP bound was calculated from the latter experimental data. This table definitely establishes that the average values obtained for the intracellular binding of endogenous cyclic AMP in the intact organ seem to correlate with its cyclic AMP levels. A reciprocal plot of intracellular binding versus intracellular cyclic AMP concentrations (Fig. 6) shows that this correlation fits simple saturation kinetics very accurately. I n the unstimulated diaphragm (no theophylline nor epinephrine added to the incubation medium) about 50 °/, of the available binding sites are occupied by endogenous cyclic AMP; this Eur. J.

Various treatments with one of the agonists alone cause endogenous bindings ranging between these two extreme values. The apparent Kd value for intracellular binding according to this plot was estimated to 330 nM f 50, as compared to the apparent Kd (33-45 nM) when binding was assayed in the extracts (Fig. l and 2). Hence a difference of about one order of magnitude appears to obtain between the Kd values calculated within the cell and the 84 Intracellular Titration of Cyclic AMP-Receptor Protein Binding same constant measured with diaphragm homogenates. The double-reciprocal plot may also be used to calculate the intracellular maximal binding capacities, from its intercept with the ordinate axis. A value of 8. 9 pm ol/mg protein was found which coincides with the values measured in the extracts by total cyclic [3H]AMP exchange. This discrepancy between the intracellular Kd and the Kd measured in vitro in a variety of tissue extracts including diaphragm may a t first sight seem surprising. It has however repeatedly been pointed out that cyclic AMP concentration even in the unstimulated cell was far in excess of the concentration which should result in almost maximal stimulation of protein kinases and compartmentalization of the nucleotide within the cell has usually been postulated to explain this contradiction [8,9,20]. The present work shows that despite these high intracellular concentrations of cyclic AMP, protein kinases could indeed not be fully activated, since under the same conditions, the receptor proteins appear not to be fully saturated with cyclic AMP. Concluding Remarks As might have been expected from Equation (1) (if this reaction truly reflects intracellular conditions) a rise in cyclic AMP should be paralleled by an increase in the amount of cyclic AMP bound to receptor protein in the cell. The results reported show this indeed to be the case in the isolated rat diaphragm: when this tissue is stimulated by various agents which increase the level of cyclic AMP the amount of protein receptors endogenously saturated by cyclic AMP (R cyclic AMP) rises, as indicated in our experiments by a decrease in their ability to bind exogenously added cyclic [3H]AMP after tissue extraction. Maximal binding capacities for cyclic AMP do not seem to be affected under any circumstance. A parallel approach t o the study of this problem has been undertaken by Corbin et al. [12] and Soderling et al. [13] who investigated in adipose tissue under various stimulatory conditions, the state of activation of the catalytic subunit (C) by assaying the cyclic AMP dependence of the protein kinase in tissues extracts. These authors demonstrated that under well-defined xperimental conditions, there was a quantitative relationship between the intracellular level of cyclic AMP and the amount of the active C unit which could be separated from the complex protein kinase RC. However in their experiments high concentrations of NaCl had to be added to the extracts, since in its absence R and C tended to reassociate almost immediately, indicating that cyclic AMP is no longer bound to its receptor protein (R). The situation in various other tissue xtracts has been found to be analogous, except wit h skeletal muscle, where preliminary results obtained by the authors led them to suggest that the protein kinase subunits do not readily reassociate. This seems also to be the case for the diaphragm, since under the conditions of the present work, it has been possible to titrate for R * cyclic AMP in the crude extracts even in the absence of high salt concentrations : acccurate estimations of intracelM a r binding of cyclic AMP have been obtained and correlated with the absolute amounts of the nucleotide present in the stimulated and unstimulated cell. The binding seems t o obey simple saturation kinetics but the apparent Kd of this binding is about10 times higher as compared with the crude extracts. These results may be explained by cyclic AMP compartmentalization within the cell ; in this case, however, the simple saturation kinetics would indicate that the various pools of the cyclic nucleotide attain equilibrium very rapidly. Or else, if cyclic AMP within the cell is not compartmentalized, and if the reaction described by Equation (1) may be applied, without any modification, to intracellular equilibria, a decrease in the apparent Kd could be merely a consequence of the dilution (about 10-fold) of the protein components during extraction of the tissue, while cyclic AMP concentrations are maintained by the addition of exogenous cyclic [3H]AMP. However these two hypotheses are certainly oversimplified, since they do not take into account factors like the intracellular concentration of the heat-stable kinase inhibitor [21,22], ATP or Mg2+ [19,23], which are known to affect cyclic AMP binding either in crude extracts or with purified protein kinase preparations. It seems impossible to decide at present which of these interpretations is most likely to reflect true intracellular conditions. It is noteworthy that the apparent Kd estimated is close to the intracehlar cyclic AMP concentration of the nstimulated tissue, a fact which should account for maximal sensitivity of the regulatory mechanisms under physiological conditions. Hormonal controls at the level of cyclic AMP-receptor protein interaction have hitherto never been described; the data reported above provide a suitable means for investigating such problems.

Elements of Compensation Packages

Question: Write an essay on Elements of Compensation Packages. Answer: From the given case, it is notable that Bill Strong, who has been the Chief Executive Officer (CEO) and founding Director of the Strong Built Construction Company, has designated Susan Bold as the companys new Chief Financial Officer (CFO). Currently, the industry has witnessed a state of depression however this has not majorly affected the company. Despite this, a conducted survey disclosed that the company is facing an issue regarding poor employee motivation. The present approach of rewarding employees involves providing them with company shares. Bill believes that the approach of conventional agency theory motivates employees by providing them with monetary benefits. However, Susan has a different perception, who believes that intrinsic considerations are necessary while rewarding employees. Contextually, this part of the assignment will create a report from the perspective of Susans assistant. Elements of Compensation Packages There are different elements of compensation packages that the company can consider while rewarding its employees. In this regard, Gerhart, Minkof and Olsen (1995) suggested the base salary as one of the decisive aspects of employee compensation packages, which is the fixed salary paid based on the work performed. Moreover, according to Fogleman and McCorkle (2009), the compensation package to the employee includes bonuses, which may be on annual, half-yearly or quarterly basis. This largely motivates employees to perform well and contribute to the attainment of organizational goal. Besides, bonuses are provided for outstanding performances. According to the report published by Labour Department (2015), for employees motivation, companies provide compensations for health and wellness, which include medical, vision, dental and other health related assistance. Gerhart, Minkof and Olsen (1995) also suggested that several companies provide life and accident insurances to its employees, w herein monetary and other assistances are provided for accidental death of the respective employees, long-term disability and dismemberment. These types of compensations largely motivate employees and influence them to be loyal to the company. Furthermore, for attracting employees, several companies provide free travelling opportunities (Labour Department, 2015). In addition, the compensations such as food subsidy, internet services, cell phones, membership in premium clubs, and education funding among others provided to the employees motivate them to perform well (Gerhart, Minkof and Olsen, 1995). Thus, it is apparent that there are several different elements of compensation, which the Strong Built Construction Company can provide to motivate its employees. Assumptions of Traditional Agency Theory and Their Influence on Compensation There are certain key assumptions of traditional agency theory, which largely influence the concept of compensation. In this regard, Kivisto (2007) mentioned human assumptions as one of the forms of the theory, wherein most of the people within an organization are conscious about self-interest. It is assumed that the manager, the owner, as well as the employees of Strong Built Construction Company have self-interest, which in turn largely influences compensation. Human assumption also indicates the risk aversion characteristics of the manager as well as the employees, which considerably affect their performance, thereby resulting into low compensation. Human assumption also involves the bounded rationality, which suggests that the manager and the owner make decisions based on the limited information that they possess regarding the employees. This in turn largely affects their compensation (Rodriguez, Gomez-Meizia and Wiseman, 2012; Kivisto, 2007). The other assumption of the traditional agency theory as mentioned by Kivisto (2007) is the organizational assumption, which indicates the persistence of goal conflicts among the internal stakeholders of the company. In the current company, there is a possibility that the owner, manager, and the employees have different individual goals. The employees might perform differently with respect to organisational goal, which in turn affects their compensation. Moreover, organisational assumption also includes the information irregularity between the owner and the manager. This affects the decision making process, thereby hampering the employees compensation benefits to a large extent (Rodriguez, Gomez-Meizia and Wiseman, 2012; Kivisto, 2007). Difference and Relationship between Extrinsic and Intrinsic Motivation Ims, Pedersen and Zsolnai (2014) suggested of the relationship and difference between intrinsic and extrinsic motivation. In this context, the relationship between both these forms of motivation is to provide certain rewards to the individuals, which in turn encourages them to perform well. In the current organization, both these types of motivation encourage the employees to participate in the organizational decision-making and share common goal of interest. Thus, the relation between these motivations is to ensure mutual benefit of the employees as well as the organisation. However, extrinsic motivation occurs to gratify the external needs of an individual. On the other hand, intrinsic motivation attempts to satisfy the personal needs and desires of an individual. Extrinsic motivation factors are largely similar for different individuals. However, intrinsic motivation factor differs from individual to individual. Therefore, identification of intrinsic motivation factor is difficult in comparison with the extrinsic factors of motivation (Ims, Pedersen and Zsolnai, 2014; Sansone Harackiewicz, 2000). Employees Attitude Influencing Compensation Package Pepper and Gore (2014) mentioned that there are two types of employee attitude within an organization, which are risk adverse and risk seeking. In relation to the concerned organization, the employees with an attitude of risk adverseness avoid taking additional responsibilities. This in turn affects their compensation. Besides, the risk adverse attitude of employees also discourages the manager as well as the owner to keep trust on them, which eventually affects their professional growth. On the other hand, the manager and the owner of the organization are highly encouraged by observing the risk-seeking attitude of the employees. Correspondingly, they trust the respective employees and offer higher responsibilities. Subsequently, they receive higher professional growth, which significantly increases their desired compensation (Pepper and Gore, 2014; Kumar, 2010). Time-Period Influencing Employees Desire for Benefit Pepper and Gore (2014) suggested that the time when employees attain compensation benefit is a very decisive factor. Appropriate time of receiving the compensation by the employees largely influences their desire of availing the benefit. Concentrating on the given scenario, if the employees receive health or medical insurance support at the time of need, they will be highly satisfied. Besides, bonuses at the time of festive-occasions influence the employees to have greater desire for the benefit. Employees also desire for the base salary benefit to be received at the specified date of every month. On-time availability of the benefits largely motivates the employees, which in turn influences them to be loyal to the company and attain their desired benefits (Pepper and Gore, 2014). Role of Fair Consideration on Compensation Pepper and Gore (2014) mentioned that fair consideration to the employees of an organization plays one of the major roles in determining appropriate compensation. It is applicable to the given construction company as well. In this regard, fair consideration plays a significant role in ensuring desirable compensation, which in turn motivates employees to perform better. This encourages them to attain their individual objectives aligned with the organisational goal. The employees, who are not performing expectedly, are motivated because of fair consideration. Thus, fair consideration has the role of improving the employee productivity, which in turn ensures their professional growth, thereby determining greater amount of compensation (Greene, 2010; OECD, 2009). Executive Compensation Committee Benefiting in Determining Compensation The introduction of Executive Compensation Committee in Strong Built Construction Company will be of significant benefit in determining the appropriate compensation. The reason behind this as mentioned by Hermanson, Tompkins, Veliyath and Ye (2012) is that it ensures long-term incentive plans to the employees, which eventually contributes to employee loyalty in the organisation. Besides, it considers appropriate compensation philosophy, which involves the attainment of organisational goals, retention of employees, connection of the employee compensation with organisational goals, and providing fair as well as reasonable compensation. The committee also considers suitable documentation process, which ensures the determination of appropriate compensation (Sirkin Cagney, 2015; Reda, Reifler Stevens, 2014). Structuring of Executive Compensation Committee Strong Built Construction Company to obtain the best outcomes with respect to compensation requires introducing an Executive Compensation Committee. In this regard, for appropriate structuring of the committee, the organisation requires considering some of the decisive aspects. One such aspect as stated by Hermanson, Tompkins, Veliyath and Ye (2012) is the size of the committee, which typically comprises three to five individuals. Moreover, for appropriate structuring of the committee, the board of directors requires appropriate selection of the committee members. The selection is based on the qualification and knowledge of the members, their experience in the professional field along with adequate training (Sirkin Cagney, 2015; Reda, Reifler Stevens, 2014). Conclusion From the above discussion, it is apparent that for Strong Built Construction Company, determining appropriate compensation is necessary. Thus, it is recommended that the organisation apart from providing shares to the employees must offer compensations such as bonuses, health and medical insurance and other facilities. Moreover, it is also recommended that the company must focus on providing intrinsic motivation to the risk-seeking employees. It should also consider appropriate time and fair consideration while providing compensations. Furthermore, it should introduce an Executive Compensation Committee for determining appropriate compensation. Aim of the Research The mandatory implementation of revised ISA 700 Auditors report attempts to lessen the Audit Expectation Gap. Thus, considering this aspect, the research by Gold, Gronewold and Pott (2012) attempted to examine its effectiveness. Elaborately, the research aimed towards evaluating the present state of the audit expectation gap in Germany with respect to that of the revised ISA 700 auditors report through several experiments. The research also aimed at taking the support from several business students as unsophisticated users and business analysts as sophisticated clients, along with the auditors who have considerable experience performing in the field of work. These individual groups were asked to evaluate an unqualified ISA 700 auditors report. They were also correspondingly requested to provide response regarding the roles as well as responsibilities of the management and of the auditors along with the reliability of audit reports. Purpose of Manipulation Check Gold, Gronewold and Pott (2012) perceived that the respondents might change their response after reading the subsequent questions. Thus, the purpose behind conducting the manipulation check is to ensure that the respondents do not go back to the previous question of the dependent variables after reading the corresponding questions. Thus, manipulation check ensured true and appropriate response of the provided questions. Research Aim The aim of the study by Agyei, Aye and Owusu-Yeboah (2013) is to evaluate the persistence of Audit Expectation Gap in Ghana. This assessment is made from the perspective of stockbrokers and auditors. The rationale behind conducting this particular research is that there have been no previously conducted studies relating to the Audit Expectation Gap in Ghana. On the other hand, the conducted study by Okafor and Otalor (2013) aimed at determining whether people are familiar with the regulatory, legislative and professional statements of the auditors. It also aimed to determine whether the responsibilities and duties of the auditors are appropriate to conduct. Research Approaches in the Studies Agyei, Aye and Owusu-Yeboah (2013) in their study to determine the audit expectation gap in Ghana incorporated qualitative approach, wherein calculation of no quantitative data has been conducted. The qualitative approach of measuring the audit expectation gap in Ghana has been done through the logical interpretation of collected data along with the concept generated from the literature sources. On the other hand, the research conducted by Okafor and Otalor (2013) integrated mixed approach, which involved both quantitative as well as qualitative analysis. The integration of mixed approach supported in cross-validation of data. Thus, noting both the approaches used in the respective studies, it can be evaluated that the mixed approach used in Okafor and Otalor (2013) is more rigorous. Owing to such approach, the results derived are believed to be more reliable, valid and relevant. Research Participants in the Studies The study by Agyei, Aye and Owusu-Yeboah (2013) selected 20 stockbrokers along with 20 auditors as the participants for questionnaire survey. These participants were selected based on purposive sampling, believing that the stockbrokers and the auditors have provided valid, reliable, and relevant information. On the other hand, the research conducted by Okafor and Otalor (2013) involved randomly selected teachers and students from the University of Benin, Ambrose Alli University, Benson Idahosa University, Ekpoma, the investing public along with the Accountants in Practice in Edo State. On a comparing note, it can be evaluated that although the study by Okafor and Otalor (2013) integrated random sampling to reduce biasness, the research by Agyei, Aye and Owusu-Yeboah (2013) is more rigour with respect to selection of research participation. The reason behind such is that the involved participants, i.e. auditors and stockbrokers have adequate and appropriate knowledge regarding audit e xpectation gap. Response Rate in the Studies The respondents involved in the research conducted by Agyei, Aye and Owusu-Yeboah (2013) was a total of 40, which comprised 20 stockbrokers and 20 auditors. Although the response rate was not significantly high in the study, the participants involved are extensively proficient in providing appropriate responses. However, the questionnaire survey conducted by Okafor and Otalor (2013) involved 130 respondents. In spite of the returned 94 questionnaire from the 130 respondents, which accounted to 72%, the value is sufficient to give unbiased result as a whole. Data Analysis in the Studies In the study by Agyei, Aye and Owusu-Yeboah (2013), the collected primary and secondary data are analysed through qualitative method. Elaborately, logical interpretation technique was used to analyse the collected data. The primary data that were collected from questionnaire survey were analysed and justified with the support of the concept developed from literature sources. On the other hand, in the research by Okafor and Otalor (2013), mixed analysis has been incorporated, which involve both quantitative and qualitative methods. The collected primary data were analysed through ANOVA, logit and probit, along with multiple regression, which supported in hypotheses testing. The collected primary data were also analysed from the concept generated from secondary sources. The use of both quantitative and qualitative method for analysis supported in cross validation of data, which thereby ensured greater reliability, validity and relevancy of research outcome. Thus, considering these aspe cts, it can be evaluated that the data analysis method used in Okafor and Otalor (2013) is more rigor. Moreover, the use of comparatively greater number of secondary sources in the study also ensured its analysis to be more rigorous. Two Other Significant Flaws in the Studies The study conducted by Agyei, Aye and Owusu-Yeboah (2013) involved only stockbrokers and auditors as participants. In this regard, it can be commented that there are several users of financial statements, which were not involved in the study. Besides, the study did not incorporate quantitative analysis, which could have led to a further comprehensive research. Okafor and Otalor (2013), in their research have not included open-ended questions and interview. The other flaw in the study is that there were several secondary data considered that were published decades back. This limits its relevancy to the current day context.

Haunting Of Hill House Essays (932 words) - English-language Films

Haunting Of Hill House The Haunting of Hill House is considered a classic to many people. It has a certain sense of feeling missing from today's novels. The Haunting of Hill House has suspense, horror, a little bit of romance, and an ending that will leave you thinking for days. Shirley Jackson is well known for her twisted work. At the beginning of the book, you our introduced to a character that has a major impact on all of its "guests". Hill House. "Hill House, not sane, stood by itself against the hills, holding darkness within." This is just one of the chilling sentences from the opening paragraph. The fear begins to set in. Shortly after, you are introduced to the strong yet cautious Dr. John Montague. He is a doctor of philosophy and has a new study up his sleeve. He is going to rent the "haunted" Hill House and document all that goes on. To accompany him and further the study, are three assistants. After considerable research, three patients are chosen. Eleanor Vance, Luke Sanderson, and Theodora (Theo) are the chosen few. You are first brought into the life of Eleanor Vance. Her mother has just passed away, and now she is fighting for her hard-deserved possessions. Eleanor has never been accepted. She has always been on her own and liked it that way. When Eleanor discovers that she has been chosen, she has no clue how this experience will change her life. Next, we are introduced to Theodora. Her last name is never revealed which gives her a sense of mystery. Theo could be considered any man's dream. She is quite beautiful and has that certain something. Theo gladly accepts the invitation to Hill House, and nothing more is said. Luke Sanderson is the future inheritor of Hill House. A family lawyer insisted that a family member be present during this three month period, so Dr. Montague gladly chose Luke. Shortly after, Eleanor, Theodora, Luke, Dr. Montague, and his secretary arrive at Hill House. They are introduced to the mysterious housekeepers, the Dudleys. Theo and Eleanor quickly form a bond and explore the home. They discover how elaborate and titanic Hill House is. The fireplace, walk out veranda, and library are just some of the things that the girls discover. Everyone loves the house for its beauty and extravagance. Later on in the evening, Dr. Montague tells the long history of Hill House. It was owned by Hugh Crain. He had two children, but their mother was killed in a carriage accident just before she arrived at the house. His second wife died from a fall, possible suicide. Crain's third wife died of tuberculosis. Shortly after, Crain passed away in Europe. His two daughters were left with the house, but many fights occur over who should get it. The older sister dies, and the young sister ends up owning it. She commits suicide, and Hill House is left to the Sandersons. The first night was fine, but many things begin to happen. The following night, Theodora and Eleanor have a terrifying encounter. While sleeping, Eleanor hears a pounding sound. She wakes up. The sound continues, so she rushes to Theodora's room. The room becomes ice cold, and the pounding becomes louder. After an intense amount of time, Dr. Montague and Luke arrive. Another thing is discovered by the guests. Outside of the nursery, a cold spot occurs. Nothing can be explained about the cold feeling, but it occurs every time they walk passed it. Over time, Eleanor sees and feels the presence of a superior "being". The following quotation comes from the chilling moment when Eleanor discovers no one is in her room: "God God-whose hand was I holding?" Over time, Eleanor becomes attached to the house. She feels like the house is talking to her. On one occasion, "WELCOME HOME ELEANOR" was written over Theo's room and clothing. It was written in blood. Eleanor becomes furious, thinking her fellow spouses wrote the frightening message. Then again, she feels like the house is speaking to her. She feels like Hill House is part of her. Later on, this "obsession" goes one step too far. Towards the end of the book, Mrs. Montague arrives at Hill House. With her, she brings planchette. Planchette is a form of the ouija board. With planchette, Mrs. Montague can contact the spirits of the house. In her planchette sessions, the names Nellie, Nell, and Eleanor are brought up many times. This feeds the obsession of Eleanor and Hill House. After

Daddy, Vampires, Black Hearts Essays - Daddy, Sylvia Plath, Plath

Daddy, Vampires, Black Hearts Essays - Daddy, Sylvia Plath, Plath Daddy, Vampires, Black Hearts In the poem Daddy, Sylvia Plath says that there are women who, due to early conditioning, find themselves without the tools to deal with oppressive and controlling men. They are left feeling helpless and hopeless. For some women, the struggle is never resolved, others take most of a lifetime. For a lucky few, they are granted a reprieve. The speaker in this poem is Sylvia Plath. The poem describes her feelings of oppression and her battle to come to grips with the issues of this power imbalance. The poem also conjures the struggle many women face in a male dominated society. The conflict of this poem is male authority and control versus the right of a female to be herself, to make choices, and be free of male domination. Plaths conflicts begin in her relationship with her father and continues with her husband. The intensity of this conflict is extremely apparent as she uses examples that cannot be ignored. The atrocities of NAZI Germany are used as symbols of the horror of male domination. The constant and crippling manipulation of the male, as he introduces oppression and hopelessness into the lives of his women, is equated with the twentieth centurys worst period. Words such as Luftwaffe, panzerman, and Meinkampf look are used to descibe her father and husband as well as all male domination. The frequent use of the word black throughout the poem conveys a feeling of gloom and suffocation. Like many women in society, we know that Plath felt oppressed and stifled throughout her life by her use of the simile I have lived like a shoe for thirty years poor and white, barely able to breath or Achoo. The use of similes and metaphors such as Chuffing me off like a Jew. A Jew to Dachau, Auschwitz, Belson. and I think I may well be a Jew clearly shows the feelings of anguished hopelessness and the ripping agony she must have felt. The agelessness of this poem is guaranteed as there will always be women who feel the same torture that is described. . Strong images are conveyed throughout the poem. The words marble- heavy, a.bag full of God conveys the omniscience of her fathers authority and the heaviness it weighed on her throughout her life. The vampire who said he was you, and drank my blood for a year, seven years if you want to know describe her husband and the ability of male power to strip a person of their own sense of themselves. The poem is written in stanzas of five short lines. These lines remind me of a Mike Tyson jab, short but extremely powerful. An example of this If Ive killed one man Ive killed two The vampire who said he was you. The powerful imagery of these lines overpowers any of the rhyme scheme. The tone of this poem is an adult engulfed in outrage. This outrage,at times, slips into the sobs of a child. This is evident by Plaths continued use of the word daddy and the childlike repitition You do not do, you do not do and Daddy, daddy, you bastard. Fear from her childhood moves her in directions that will take her far from herself. In one line in the poem she brings us starkly into the world of a childs fear. She uses words that sound like the words of a child staring out at us from behind a bardwire snare I have always been scared of you. This poem portrays a bleak picture of life for some women. However, we know that Plath was able to resolve her conflicts. She states Daddy Ive had to kill you and Daddy, you can lie back now. Theres a stake in your big fat black heart Athough it appears that Plath has reached resolution this is not the case for many women who find themselves under the thumb of a male. These women should look to this poem for help. It is a beautiful argument that clearly shows that she climbed from total domination by a male to freedom

An Unannounced Inspection Case Study Example | Topics and Well Written Essays - 1000 words

An Unannounced Inspection - Case Study Example Likewise, it was noted that the plant manager is not within the premises and the area where the employee who complained works is reported to be currently undergoing a major renovation for a process change for the product in the line. The Questions and Responses How would you act, what actions should you take, and what would you do? According to OSHA inspection standards, employers should be aware that inspections are regularly conducted without the need for advance notice or any presentation of warrant to inspect. In this case, an employee reported a complaint, which is one of the requirements where OSHA would be able to enter and inspect the worksite without obtaining a warrant or even the employer’s express consent. Therefore, the only expected and appropriate action that should be taken is to allow the OSHA inspector to undertake the needed inspection and to address all inquiries or questions regarding the complaint in the worksite under major renovation; with proper advice of the matter from the plant manager. One could call the authorized officer in charge of safety and the plant manager just to formally advise them that the OSHA inspector is currently at the plant and to enable one to effectively assist the inspector, as duly and lawfully required. Should you challenge the validity of the OSHA inspector's request, or their right to enter the workplace? One has not authority to challenge the validity of the OSHA inspector’s request because by virtue of law, specifically relating to â€Å"Section 5(a)(1) of the Act, known as the â€Å"General Duty Clause,† which requires that every working man and woman must be provided with a safe and healthful workplace† (Occupational Safety & Health Administration, 2002, p. 1), the disgruntled worker has the right to forward any perceived concern that could possible endanger his health and safety in the work setting. Or should you request a warrant to enter the workplace, and thereby gain some time to make sure everything is in order back in the plant? There really is nothing to hide at the plant and the OSHA inspector could even assist in recommending the most appropriate methods to ensure that safety and security of the workers are addressed; while the major renovation for a process change for the product in the line is taking place. Can you gain any time to check with your in-area safety supervisor first? Or, should you immediately comply with the request for the inspection? Explain your answers. As previously noted, one strongly believes that the policy of the organization in terms of reporting relevant incidents (including the area safety supervisor and even the plant manager) must be followed and adhered to. Doing so does not mean that one is buying extra time but following protocols and policies in reporting relevant incidents within the organization for proper approval, as needed.

Ethics and Law in Business and Society Research Paper

Ethics and Law in Business and Society - Research Paper Example Significant analysis and evaluation of the policies have been conducted to determine the effectiveness of these policies. Lastly, the study will provide some recommendation plans in order to overcome the possible issues and challenges. History of the Act It is important for the government, authorized bodies and employers to take care of the needs of the employees in an organization as employees are considered as one of the major assets of an organization. Significant work performance of the skilled and effective employees helps the business organization to achieve significant growth rate. In addition to this, effective business performs ace of the business units ensures economic growth of a nation. This specific act or program was required in order to cover and support the basic rights of the employees in an organization. This Federal Employees’ compensation act was developed in the year 1916 to ensure social welfare. This act was developed in order o support those employees w ho are physically or mentally unable to justify job responsibility. The major objective behind the development for the acts and programs was basically for a good social cause. It was highly important for the employees who are disabled, retired or physically challenged to get the benefits from the employers or from the federal government or from the authorized bodies to look after himself and his family. These funds can be provided to all the employees who are affected due to the workplace-related issues. In addition to this, several Federal Employees’ Compensation Act programs were started to organize by the federal government in order to improve the scenario of the society. According to this act, an individual can get different benefits based on the eligibility. The elements of the Federal Employees’ Compensation Act program include several aspects. According to this act, each and every mentally or physically affected employee in a workplace can get significant compen sation or service benefits (Ullmann, 2003). It is important for an organization to ensure healthy and safe workplace environment. The federal government of United States of America supported this act and act related programs to ensure the security of each and every disabled employee. Several types of benefit policies are proposed and developed in order to improve the lifestyle of these types of federal employees. However, the policymakers failed to develop the policy measures that created several conflicts and issues in later part. Several differentiated policies were developed and implemented under this Federal Employees’ Compensation Act in the year 1974 due to rising problems and issues in the states. however, the federal government of United States of America and other policymakers somehow failed to fulfill its overall objective due to lack of effective policy measures and i9nadequate development of eligibility criteria.

Network Monitoring And Management System Information Technology Essay

Network Monitoring And Management System Information Technology Essay A  literature review  is a body of text that aims to review the critical points of current knowledge including substantive findings as well as theoretical and methodological contributions to a particular topic. Literature reviews are  secondary sources, and as such, do not report any new or original experimental work. Most often associated with academic-oriented literature, such as  theses, a literature review usually precedes a research proposal and results section. Its ultimate goal is to bring the reader up to date with current literature on a topic and forms the basis for another goal, such as future research that may be needed in the area. A well-structured literature review is characterized by a  logical  flow of ideas; current and relevant references with consistent, appropriate  referencing style; proper use of  terminology; and an unbiased and comprehensive view of the previous research on the topic. 4.1 Domain Research 4.1.1 Network Monitoring and Management system 4.1.1.1 Introduction to the use of Network Monitoring and Management system Whenever there is vital information in an organization there has to be some agent who has to provide security measures to that information. This is because this vital information can be some sort of business plans, customer details or any kind of confidential tenders that is very important to organizational benefit. Any rival company can gain profit if it has accessed to those information by any means. Thus here arise the need and usage of network monitoring system that will be able to monitor the activities of its client. Secondly in every company one can expect there will be one network administrator. But when the number of machine increases it is difficult to manage those machines manually. Suppose one need to install some kind of programs in the client PC, the administrator has to go to that PC and then install. It is literally time consuming to go to each and every PC for initiation and finishing a set up process. Another way to solve this problem is to hire more employees for maintenance of the machines. Now this will be costly affair. So the use of Network Monitoring and Management together forms an important part of organizational computer network in day to life. 4.1.1.2 Network Monitoring and Management System The term  network monitoring  describes the use of a system that constantly monitors a  computer network  for slow or failing components and that notifies the  network administrator  (via email, pager or other alarms) in case of outages. It is a subset of the functions involved in  network management. While an  intrusion detection system  monitors a network for threats from the outside, a network monitoring system monitors the network for problems caused by overloaded and/or crashed servers, network connections or other devices. Effective planning for a network management system requires that a number of network management tasks be performed. The network management system should discover the network inventory, monitor the health and status of devices and provide alerts to conditions that impact system performance. An  intrusion detection system  (IDS) is a device or  software application  that monitors network and/or system activities for malicious activities or policy violations and produces reports to a Management Station. Intrusion prevention is the process of performing intrusion detection and attempting to stop detected possible incidents.  Intrusion detection and prevention systems (IDPS) are primarily focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators.   IDPSs have become a necessary addition to the security infrastructure of nearly every organization. Network management  refers to the activities, methods, procedures, and tools that pertain to: Operation deals with keeping the network (and the services that the network provides) up and running smoothly. It includes monitoring the network to spot problems as soon as possible, ideally before users are affected. Administration deals with keeping track of resources in the network and how they are assigned. It includes all the housekeeping that is necessary to keep the network under control. Maintenance is concerned with performing repairs and upgrades-for example, when equipment must be replaced, when a router needs a patch for an operating system image, when a new switch is added to a network. Maintenance also involves corrective and preventive measures to make the managed network run better, such as adjusting device configuration parameters. Provisioning is concerned with configuring resources in the network to support a given service. For example, this might include setting up the network so that a new customer can receive voice service. 4.1.1.2.1 Types of intrusion detection systems [B5][B6] For the purpose of dealing with IT, there are three main types of IDS: Fig: Showing type of intrusion Detection system Network intrusion detection system  (NIDS) It is an independent platform that identifies intrusions by examining network traffic and monitors multiple hosts. Network intrusion detection systems gain access to network traffic by connecting to a  network hub,  network switch  configured for  port mirroring, or  network tap. In a NIDS, sensors are located at choke points in the network to be monitored, often in the demilitarized zone  (DMZ) or at network borders. Sensors capture all network traffic and analyze the content of individual packets for malicious traffic. An example of a NIDS is Snort. Host-based intrusion detection system  (HIDS) It consists of an agent on a host that identifies intrusions by analyzing system calls, application logs, file-system modifications (binaries, password files, capability databases, Access control lists, etc.) and other host activities and state. In a HIDS, sensors usually consist of a  software agent. Some application-based IDS are also part of this category. An example of a HIDS is  OSSEC. Perimeter Intrusion Detection System  (PIDS) Detects and pinpoints the location of intrusion attempts on perimeter fences of critical infrastructures. Using either electronics or more advanced  fiber optic  cable technology fitted to the perimeter fence, the PIDS detects disturbances on the fence, and this signal is monitored and if an intrusion is detected and deemed by the system as an intrusion attempt, an alarm is triggered. 4.1.1.2.2 Comparison with firewalls Though they both relate to network security, an intrusion detection system (IDS) differs from a firewall in that a firewall looks outwardly for intrusions in order to stop them from happening. Firewalls limit access between networks to prevent intrusion and do not signal an attack from inside the network. An IDS evaluates a suspected intrusion once it has taken place and signals an alarm. An IDS also watches for attacks that originate from within a system. This is traditionally achieved by examining network communications, identifying heuristics and patterns (often known as signatures) of common computer attacks, and taking action to alert operators. A system that terminates connections is called an  intrusion prevention system, and is another form of an  application layer firewall 4.1.1.3 Components of Network Monitoring and Management System The network monitoring system basically contains different modules with the help of which proper functioning is carried out. The following are the list of modules and processes: Initial Set-Up: This is the first step while setting up a network monitoring tool. The machines must be physically connected. IP addressing should be properly carried out. Network Mapping: The system sends out a command across the network along with usage of various components to get the minimum knowledge on the model in which the network is functioning network. This model is useful for documenting the network configuration. Machine Pooling: Now the map is prepared, and the system sends the current status request to the components that are in the network. With this process the system would able to get the knowledge of any potential failures that exist in the network. Alarms Notification: The application can detect the potential failures in the existing network. Like if any system has gone out of LAN due to any cable fault or any type of other failures it will send notification to the administrator. Information about errors can be displayed centrally or even sent as an SMS message to a mobile phone Notification can be through e-Mail, SMS or Pager. Reporting: The log-sheet with the help of the command can be very useful for the system administrator to generate the idea of the type of error that has been frequently occurring. By undergoing a thorough research the developer has found out that certain processes like filtering of client, listing of process, managing clients and their processes are the basic functionalities that must be present in a network monitoring system. 4.1.1.4 Network based Application Architecture Network based application architecture can be described as the software architecture of the network based application. It provides an abstract view and the model for comparison of the architecture that is going to be used to build the system. It explains how system components are allocated and identified and how these components interact with the system. Also provides information on the amount and granularity of communication needed for interact. Along with it also gives idea on the interface protocols. 4.1.1.4.1 Client/Server Architecture [W2][W3] The client-server model distinguishes between applications as well as devices. Network clients make requests to a server by sending messages, and servers respond to their clients by acting on each request and returning results. One server generally supports numerous clients, and multiple servers can be networked together in a pool to handle the increased processing load as the number of clients grows. C:UsersJAYESHPicturesfeatures-client-server.jpgC:UsersJAYESHPicturesclient_server_architecture.jpg Fig- A Client-Server Network The  client-server model  of computing is a  distributed application  structure that partitions tasks or workloads between the providers of a resource or service, called  servers, and service requesters, called  clients.  Often clients and servers communicate over a  computer network  on separate hardware, but both client and server may reside in the same system. A server machine is a host that is running one or more server programs which share their resources with clients. In most cases, client-server architecture enables the roles and responsibilities of a computing system to be distributed among several independent computers that are known to each other only through a network. This creates an additional advantage to this architecture: greater ease of maintenance. For example, it is possible to replace, repair, upgrade, or even relocate a server while its clients remain both unaware and unaffected by that change. Client/Server architecture with respect to domain research 4.1.1.4.2 Network monitoring protocols [W12] Website monitoring service can check   HTTP   pages,   HTTPS,   SNMP,   FTP,   SMTP,   POP3,   IMAP,   DNS, SSH,  TELNET,  SSL,  TCP,  ping,  SIP,  UDP, Media Streaming and a range of other ports with a variety of check intervals ranging from every four hours to every one minute. Typically, most network monitoring services test your server anywhere between once-per-hour and per-minute. SNMP is the most well known protocol used to manage networked devices. It was to facilitate the exchange of management information between networked devices operating at the application layer of the ISO/OSI model. A collection of network management stations and network elements are implicit in the SNMP architectural model. Network management stations monitor and control network elements by executing management applications for Network devices such as hosts, gateways, terminal and servers which have management agents responsible for performing the network management functions requested by the network management stations. The Simple Network Management Protocol (SNMP) is used to communicate management information between the network management stations and the agents in the network elements. SNMP is most commonly used for remote management of network devices. SNMP is moreover known for its flexibility. Adding network-management functions to the existing system is very easy. An SNMP-managed network typically consists of three components: Managed devices Agents Network management systems A managed device can be any piece of equipment that sits on your data network and is SNMP compliant. Routers, switches, hubs, workstations, and printers are all examples of managed devices. An agent is typically software that resides on a managed device. The agent collects data from the managed device and translates that information into a format that can be passed over the network using SNMP. A network-management system monitors and controls managed devices. The network management system issues requests and devices return responses. 4.1.1.5 HCI (Human Computer Interaction) Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them. Association for Computing Machinery As Smart Whistle Blower- a network management and monitoring tool completely functions according to the user. That is why developer tried to implement peoples interaction with computers and to develop the computers for successful interaction with human by the concept of HCI (Human- Computer Interaction). The developer used following main parts of HCI: User Computer Interaction The developer implemented HCI with the aim of improving the interactions between humans and computers by making computers more usable and receptive to the users needs. Usability can be defined as the extent to which the system can be learnt and used by the users. So the developer measures the usability of the system by analyzing the following points: Easy to learn Effective to use Efficient to use While developing a system using HCI principles the following factors must be considered by the developer: Organizational Factors Environmental Factors Health and Safety Factors Comfort Factors People System/Network Administrator Supervisor Advisor HCI now is being used in a wide range of fields which are shown in the diagram below: Fig: Showing related modules to HCIU Source: http://images.google.co.in/imgres?imgurl=http://www.deepamehta.de/docs/images/talk/39-middle.png 4.1.1.6 Market Research 4.1.1.6.1 Similar software available in market There are numerous monitoring tools available in the market, some of which are listed below: Application Monitoring Performance Monitoring Database Monitoring Security Monitoring Environment Monitoring Network Traffic Monitoring PC Monitoring Protocol Analyzing 4.1.1.6.2 Comparison Chart [W13] [W14] [W15][W16][W17][W18][W19][W20] Fig: Showing Comparison Chart between ten software and Smart Whistle Blower A Brief Analysis On a comparison with 10 network monitoring system it has been found that the proposed software i.e. Smart Whistle is providing many such facilities that the current network monitoring system do not have. The comparison has been done on nine different features that network monitoring and management software must have. The features commonly are as follows: [Æ’Â  ] Logical Grouping [Æ’Â  ] Distributed Monitoring [Æ’Â  ] Hardware Intrusion Detection [Æ’Â  ] WebApp [Æ’Â  ] Auto discovery [Æ’Â  ] Triggers/alerts [Æ’Â  ] Live Screening [Æ’Â  ] Chat enabled [Æ’Â  ] Support Network Management System 4.1.2 Security management recommendation Security Management for networks is different for all kinds of situations. A small home or an office would only require basic security while large businesses will require high maintenance and advanced software and hardware to prevent malicious attacks from  hacking  and  spamming. Small homes A basic  firewall  like COMODO Internet Security or a  unified threat management  system. For Windows users, basic  Antivirus software  like  AVG Antivirus,  ESET NOD32 Antivirus,  Kaspersky,  McAfee,  Avast!,  Zone Alarm Security Suite  or  Norton Antivirus. An anti-spyware program such as  Windows Defender  or  Spybot Search Destroy  would also be a good idea. There are many other types of antivirus or anti-spyware programs out there to be considered. When using a wireless connection, use a robust password. Also try to use the strongest security supported by your wireless devices, such as WPA2 with AES encryption. Enable MAC Address filtering to keep track of all home network MAC devices connecting to your router. Assign STATIC IP addresses to network devices. Disable ICMP ping on router. Review router or firewall logs to help identify abnormal network connections or traffic to the Internet. Use passwords for all accounts. Have multiple accounts per family member, using non-administrative accounts for day-to-day activities. Disable the guest account (Control Panel> Administrative Tools> Computer Management> Users). Raise awareness about information security to children. Medium businesses A fairly strong  firewall  or  Unified Threat Management  System Strong  Antivirus software  and Internet Security Software. For  authentication, use strong passwords and change it on a bi-weekly/monthly basis. When using a wireless connection, use a robust password. Raise awareness about  physical security  to employees. Use an optional  network analyzer  or network monitor. An enlightened administrator or manager. Large businesses A strong  firewall  and  proxy  to keep unwanted people out. A strong  Antivirus software  package and Internet Security Software package. For  authentication, use strong passwords and change it on a weekly/bi-weekly basis. When using a wireless connection, use a robust password. Exercise  physical security  precautions to employees. Prepare a  network analyzer  or network monitor and use it when needed. Implement  physical security  management like  closed circuit television  for entry areas and restricted zones. Security fencing  to mark the companys perimeter. Fire extinguishers  for fire-sensitive areas like server rooms and security rooms. Security guards  can help to maximize security. School An adjustable  firewall  and  proxy  to allow authorized users access from the outside/inside. Strong  Antivirus software  and Internet Security Software packages. Wireless connections that lead to  firewalls. Childrens Internet Protection Act  compliance. Supervision of network to guarantee updates and changes based on popular site usage. Constant supervision by teachers, librarians, and administrators to guarantee protection against attacks by both  internet  and  sneaker net  sources. security via firewall Large government A strong  firewall  and  proxy  to keep unwanted people out. Strong  Antivirus software  and Internet Security Software suites. Strong  encryption. White list authorized wireless connection, block all else. All network hardware is in secure zones. All hosts should be on a private network that is invisible from the outside. Put web servers in a  DMZ, or a firewall from the outside and from the inside. Security fencing  to mark perimeter and set wireless range to this. 4.1.3 Service and Technology Growth in India As India emerging as one of the major IT leaders of the world, more and more IT companies are establishing in the present scenario. With the increase in IT companies more competition will arise in the market, as a result there will be increase in business politics and hence everybody will try to win this race of competition in the market. Thus there is high risk of hackers intruding into company database and taking away vital information and selling them to rival company. So here the importance of Network Security arises. As a result more and more number of Network Monitoring and management systems is being developed. On a detailed research it has been found that the number of cases of cyber crime is increasing every year. With practical guidance  delivered by expert speakers  an organization named as e-Crime  India is the premier networking and knowledge initiative for security, IT, fraud, investigations, CERT, audit, forensics, and compliance professionals who are responsible for  protecting against existing attacks and emerging threats.   Major IT companies in India like the Infosys, TCS, and Wipro etc. are having separate department to develop software related to network security. Hence one can say the importance of developing such a system because this type of software is ever- demanding with the increase and development of technology. 4.2 Information and Resources Networks Networking Concepts Computer Networks and Internets with Internet Applications, 4th International Edition, Douglas E Comer, Ralph E.
