Organizational Behavior Terminology and Concept - 779 Words

Organizational Behavior Terminology and Concept When small business owners start the concept of what type of business one would like to own, an array of critical thinking starts and a business owner has to consider questions that will make or break his or her success. Owners, who pay attention to the current rise and fall of stock for his or her chosen business, will have the upper hand against competitors. An owner who knows his or her competitors is a small part in the grand scheme of owning an organization. Owners who give attention to the needs and wants of employees and customers will have a higher rate of profit and a lower rate of employee turnover. Organizations that learns and knows the ends and outs of maintaining a business†¦show more content†¦Knowing these terminologies will help an organization implement policies that will help everyone to know what to do, how to treat each other, and what the boundaries are. Understanding the terms is not the only part but implementing these terms in organizations can make a big difference on how employees treat each other. Communication is the transfer and the understanding of information. Diversity is the different ages, races, gender, sexual orientation, and physical ability (Robbins Judge, 2009). These two terms play important roles with each other and within organizations. An organization who has a diverse culture can arrive at aspects, suggestions, and ideas from all different individuals in the organization. This can create a steady communication between employers and employees of all different types as well as keeping communication with existing and prospective customers. Business ethics is the everyday moral or ethical norms to business as stated by De George (2010). When an organization puts a set of rules or beliefs for everyone to follow every day, this is what helps the business to run smoothly. When a change happens, which can be a new policy or new rules, an organization has to learn and be willing to accept change, and this is a rough definition of change management.

Online Learning V/S Face To Face Learning

Question: Discuss about theOnline Learning V/S Face To Face Learning. Answer: Research Questions: The topic chosen for this assignment is the comparison between online learning and face to face learning. The research will draw attention to the inclination of the students towards online learning as compared to face to face learning, and whether online learning distracts students. Moreover the study will focus on students perspectives on face to face learning and which module they find optimal for understanding the topics. Literature Review: The students of current tech savvy generation are more inclined than ever to the wonders of internet. Every other student nowadays is more acquainted with the internet bas4ed learning than same old boring lecture system. McCann, Schneiderman Hinton (2010) in the article has explained the preferences of dental study students over e-learning and face to face learning (McCann, Schneiderman Hinton, 2010). The results indicated at the fact that the students wanted e-materials because of the ease in understanding due to interactive modules but only as a back up and they do not prefer to have online learning replace the lecture system completely. Liu (2011) in his article explained about the factors that can diminish the quality of learning when utilizing the online domain. His study very clearly accentuates at the gaps left behind in the learning experience due to computer anxiety, lack of knowledge in using technology, he also pointed out a key fact in this discussion that different students have different preferences; some are comfortable with online learning while some are not (Liu, 2011). Winter et al. (2010) in his article has also explained how the majorities of the students find online learning cumbersome and distracting (Winter et al., 2010). However consensus is in spite of the conspicuous drawbacks of e learning why students are lured more and more into the e learning modules. Xu and Jaggars in their article encompassing a huge number of respondents have explained that athere4 are different factors that attract some to the online learning while repel the rest (Xu Jaggars, 2013). This research will attempt to analyze the factors in details, what attracts the students to the e-learning and determine why some find it difficult to cope with. Methodology and Data Collection: The method chosen for data collection is quantitative, as it provides quickest and most genuine results that also are converted into numerical data for ease in analysis. Questionnaires were prepared for the research studies which were distributed among a selected group of students. Ethical Approval: As the research study will collect information from different individuals hence consent was extracted from the participants to ascertain ethical practice. Other than that the researcher will the privacy and confidentiality of the data collected at all circumstances as well. Research Schedule: The duration for this research study will be approximately five weeks, the first week will comprise of designing the questionnaires, in the second week the questionnaires will be distributed, third and fourth week will have data collection and fifth week will be allotted to review and analysis. Research Llimitations: The limitation for this research would be the time constraint and the aversion in the students to participate. References: Liu, L., 2011.

To explain how the enthalpy change of neutralisation can be used to determine the relative strength of an unknown acid Essay Example

To explain how the enthalpy change of neutralisation can be used to determine the relative strength of an unknown acid Essay Monoprotic (monobasic): An acid that has only one acidic hydrogen atom in its molecules; common examples are hydrochloric acid (HCl) and nitric acid (HNO3).Prediction and Scientific Background: Standard Molar Enthalpy of Neutralisation (/Hn,) is the enthalpy change per mole of water formed in the neutralisation of an acid by an alkali, (298K and 1 atm).* Unknown Acid (aq) + NaOH (aq) Salt (aq) + Water (l)* In aqueous solution, strong acids and bases are completely dissociated and Hneut is approximately equal to -57.9 kJ mol-1. This neutralization process corresponds to the reaction: H+ (aq) + OH- (aq) H2O (l)* For weak acids, this enthalpy change is less exothermic because some input of energy is required to dissociate the acid. Therefore the Hneut of weak acids and bases is more positive than -57kJmol-1.Hydrochloric acid (strong acid): As HCl is a strong acid; it is a good proton donor, with near to complete dissociation in water. HCl (aq) H+ (aq) + Cl- (aq). Hence a strong acid completely dissociates into ions.Ethanoic acid (weak acid): As CH3COOH is a strong acid; it is a poor proton donor. The dissociation in the water is equilibrium, with the equilibrium position well to the left-hand side of the equation.CH3COOH (aq) H+ (aq) + CH3COO- (aq). For every 250 molecules of ethanoic acid, only 1 molecule dissociates and only a small proportion of the potential acidic power is released as H+. A weak acid only partially dissociates into ions.Strong Acids: When an acid dissolves in water, a proton (hydrogen ion) is transferred to a water molecule to produce a hydroxonium ion and a negative ion depending on what acid you are starting from. In the general case:These reactions are all reversible, but in some cases, the acid is so good at giving away hydrogen ions that we can think of the reaction as being one-way. The acid is virtually 100% ionised. For example, when hydrogen chloride dissolves in water to make hydrochloric acid, so little of the reverse reaction h appens that we can write:At any one time, virtually 100% of the hydrogen chloride will have reacted to produce hydroxonium ions and chloride ions. Hydrogen chloride is described as a strong acid. Thus, a strong acid is one which is virtually 100% ionised in solution. Other common strong acids include sulphuric acid and nitric acid.You may find the equation for the ionisation written in a simplified form:This shows the hydrogen chloride dissolved in the water splitting to give hydrogen ions in solution and chloride ions in solution. This version is often used in this work just to make things look easier. If you use it, remember that the water is actually involved, and that when you write H+(aq) what you really mean is a hydroxonium ion, H3O+.Weak Acids: A weak acid is one, which does not ionise fully when it is dissolved in water. Ethanoic acid is a typical weak acid. It reacts with water to produce hydroxonium ions and ethanoate ions, but the back reaction is more successful than th e forward one. The ions react very easily to reform the acid and the water.At any one time, only about 1% of the ethanoic acid molecules have converted into ions. The rest remain as simple ethanoic acid molecules. Most organic acids are weak. Hydrogen fluoride (dissolving in water to produce hydrofluoric acid) is also a weak inorganic acid.Apparatus:* 3 100cm3 beakers* 50cm3 burette* Coffee cup calorimeter: This is a simple, inexpensive device used in many general chemistry labs. It is made of two nested and capped cups made of Styrofoam; making it a very good insulator. When a reaction occurs in such a calorimeter, minimal heat is lost to the surroundings. It the reaction involves heat, for example, nearly all the heat stays within the solution in the calorimeter, where it causes an easily measured temperature increase. In the calculations involving a coffee cup calorimeter, the negligible heat absorbed by the Styrofoam will have to be ignored. This works acceptably well when the maximum temperature is reached soon after the reaction is initiated.* Glass rod* Stand and clamp* Stopwatch* ThermometerProcedure: A watch glass will be placed on an electronic balance to provide an accurate reading of its weight; this reading however is not required and may create a series of problems. Therefore to deal with this, the balance will be set to zero, so that it would not record the weight of the watch glass and consequently would only record the weight of the given solute. The white anhydrous solute, of the unknown acid will slowly be placed onto the watch glass with a spatula, so that the reading would accurately match the specified amount required: -RMM = 135Moles = 1.00MGrams (1 litre) = 135 x 1.00= 135gGrams (50cm3) = 135 ? 20= 6.75gNext a measuring cylinder will be filled with an accurate 50cm3 of distilled water. The unknown acid solute will then be poured into a clean 100cm3 beaker (labelled U). Subsequently the distilled water will be gently poured into the bea ker, making sure that any remaining solute on the watch glass will be rinsed gently into the beaker. To ensure the solute had fully dissolved, a thin glass rod could be used to grind and mix any large residual pieces this would ensure that results were not inaccurate, as the acid would be prepared incorrectly.A 100cm3 beaker (labelled NaOH) will be filled with approximately 75cm3 of sodium hydroxide (1.00M). A burette will be rinsed off with approximately 10cm3 of the sodium hydroxide, which will then be run into the sink. This consequently guarantees that each solution will not become diluted by excess water, or otherwise cause inaccurate results to arise due to the addition of any foreign chemicals from previous experiments. Moreover the beakers will be labelled according to their content, so the different colourless solutions can be clearly identified; reducing the probability of mistakes, which may cause serious problems and/or queries to arise.A stand and clamp will be acquire d to which the burette will be placed vertically. The sodium hydroxide must be steadily poured into the burette until the meniscus of the solution is in line with the measurement 0 making sure the measurements and results are as precise as possible. Subsequently the hydroxide will be run into a clean coffee cup, making sure that practically 50cm3 is contained within this calorimeter. An appropriate calorimeter for the investigation will be plastic cup, as it would sufficiently limit the amount of heat loss during the chemical reaction of neutralisation, as the material acts as an insulator, thus providing more reliable and accurate results leading to a defined inference. Afterwards the burette will be firstly rinsed off with tap water and then with approximately 10cm3 of unknown acid, which will consequently be run into the sink (to remove any excess sodium hydroxide).Similarly the unknown acid will be steadily poured into the burette until the meniscus of the solution is in line w ith the measurement 0. Then 50cm3 of the sodium hydroxide will be run into a clean 100cm3 glass beaker. At this point, two comparable thermometers will be used to test the temperature of each solution for 3 minutes; a stopwatch will be used to record the temperature (used effectively to gain accurate recordings) at 0.5-minute intervals (every 30 seconds). When the temperature is efficiently recorded the unknown acid will be added to the sodium hydroxide. Afterwards a lid consisting of a small hole (in the centre) will immediately be placed securely on the cup to ensure a minimal amount of heat is lost (due to evaporation or convection), however in this gap of approximately 10-20 seconds a significant amount of heat could be lost or gained thus causing a change (major or minor) that may result in inaccurate recordings developing. When the initial drop of the acid will be applied to the sodium hydroxide the thermometer (that fits through the specific hole) will be used to stir the mix ture and additionally record the temperature of the mixture, with the aid of the stopwatch at regular 0.5-minute intervals (every 30 seconds) for a period of five minutes. This experiment will be repeated a further two times and due to this a mean value can be obtained for the temperature change.Safety procedures: Safety glasses and gloves will be worn for health and safety reasons, and therefore as the chemicals are hazardous a risk assessment has been constructed in order to reduce the possibility of accidents or future problems. When chemicals have been used they must be sealed to confine any toxic gases being released. Furthermore chemicals may have to be placed within a fume cupboard to rid of any noxious fumes. Below is a risk assessment concerning the chemicals used within the investigation, along with information regarding potential dangers, as well as precautions that may need to be executed when dealing with an unknown acid:Chemical and Structural FormulaRisk AssessmentTox icologyAction (Personal Protection)Sodium Hydroxide (NaOH)Harmful/IrritantVery corrosive and causes severe burns. May cause serious permanent eye damage. Very harmful by ingestion. Harmful by skin contact or by inhalation of dust.Safety glasses, Neoprene or PVC gloves, adequate ventilation.Unknown AcidCould be harmful, an Irritant, highly flammable or even toxicCould causes burns, be toxic by inhalation, ingestion and through skin absorption. Could be probable human carcinogen. Could cause damage to kidneys. Could cause allergic reactions. Could cause sensitisation. Could cause heritable genetic damage. Could be very destructive to mucous membranes, upper respiratory tract as well as eyes and skin.Safety glasses, Neoprene or PVC gloves, adequate ventilation.Calculations: A concentration of 1.00M NaOH and 1.00M of the unknown acid will be used within the experiment as it provides a simple 1:1 ratio enabling calculations to be constructed without difficulty, thus limiting errors in th e analysis. Furthermore these moderately dilute concentrations are able to safely and appropriately handled under standard conditions.Results Table: Temperatures will be measured to the one decimal place. 0 will be the temperature of the reactants (NaOH and unknown acid).Time (minutes 1d.p.)0.00.51.01.52.02.53.04.04.55.0Temperature (oC 1d.p.)In order to demonstrate how the molar enthalpy change of neutralisation would be calculated, temperatures and numerical values could be practically invented, but the molarity and volumes will remain the same.Results: When 50cm3 of 1.00M NaOH at 25.5oC was added to 50cm3 of the 1.00M unknown acid at 25.5oC; in the coffee cup calorimeter, the temperature increased to a 32.4 oCAssumptions:* Because solutions are relatively dilute, it can be assumed that their specific heat capacities are close to that of water, 4.18 J/g/oC* The density of the solutions = 1.0 g/cm3 (actual density of NaOH at 25oC is 1.04 g/cm3)* There are no heat lost to the coffe e cup itself or to the surrounding air* The acid is completely neutralised* Heat evolved = Amount of Substance x Specific Heat Capacity x Temperature ChangeQ = mcTAnalysis: Two particular factors have to be calculated the systems heat capacity and the temperature change.Specific Heat = Heat Capacity/ Mass (g)By rearranging the formula: Heat capacity = Mass (g) x Specific HeatThe mass in this equation refers to the total grams of the combined solutions, but volumes are known. So the densities have to be used to calculate mass.Density = Mass/VolumeSolution: Because the densities for the solution are both 1.00 g/cm3 the cm3 are numerically the same as the grams of the solutions. Each solution mixed has a mass of 50.0g, therefore its total mass = 100.0g. We can now calculate the heat capacity of the final solution at the instant of mixing and immediately before any reaction occurs to increase its temperature. For this solution, the specific heat is 4.18 J/g/oC, so:Heat Capacity = Mass x Specific Heat= 100.0g x 4.18 J/g/oC= 418 J/oCThus the heat capacity of the solution in the calorimeter is 418 J/oC. The reaction increases the systems temperature by t = 32.4 25.5oC = 6.9 oC, so the energy evolved by the reactions can be calculated from:Heat Capacity x t = Heat Energy (Evolved)orHeat Evolved = 418 J/oC x 6.9 oC= 2.9 x 103 JThe temperature change will be obtained from a graph similar to thisNote: Four graphs will be drawn, three to display the individual temperature change for each experiment and another graph to illustrate the mean temperature change. The graphs will bare similarity to this:This is the heat for the specific mixture prepared, but joules per mole of unknown acid are required. To calculate the number of moles of the unknown acid the equation: Molarity (M) = Moles Solute1000cm3 SolutionThe molarity of the acid is 1.00M, so in 50cm3 of the unknown acid solution is 0.0500mol.50.0cm3 of the unknown acid x 1.00 mol = 0.005mol1000cm3The neutralisation of 0.0500mol of acid released 2.9 x 103 J. So, the heat released is:Energy Evolved = 2.9 x 103 J = 58 x 103 J/mol = -58 kJ/mol (exothermic)0.0500molEnthalpy: The term used for the total energy of a system when it is at constant pressure is called the enthalpy of the system, symbolised by H. Enthalpy is a state function so when a system reacts at constant pressure and absorbs or evolves energy, it experiences an enthalpy change, H, defined by:H = H final H initialH final is the enthalpy of the system in its final state and H initial is the enthalpy of the system in its initial state. H is a state function. Its value depends solely on the difference between the initial and final states and not on the mechanism by which the system undergoes this change. For a chemical reaction, the initial state refers to the reactants and the final state to the products, so for a chemical reaction the equation for H can be rewritten as follows: H = H products H reactantsIf a change is exothermic, the s ystem loses heat and its final enthalpy must be less than its initial enthalpy.Thus: H finalH initialTo calculate H from H final and H initial, larger number would have to be subtracted from one that is smaller, so the value of H for all exothermic changes is negative.Requirements: To make sure measurements, observations and recordings are reliable the experiment will be repeated to ensure measurements were precise and as accurate as possible, and therefore due to this each experiment did not provide any anomalous results. To guarantee accuracy, the glassware was washed out with water after each time of use and then dried, to prevent any foreign ions entering the solution, as it may have altered the results. However a significant limiting factor to the experiment is apparatus percentage error, which consequently affects the reliability of results, as volumes were not prepared precisely:Percentage Error of Burette = ? 0.1 x 10050.0Therefore Overall Apparatus Percentage Error = 0.2 x 2 (as the burette was used twice)= 0.4%By adding the apparatus percentage error to the result gained from each acid, it may provide an enhanced understanding of supplementary inaccuracies and faults within the experiments.Due to these results, it is evident that further discrepancies occurred within the experiments in addition to the apparatus percentage error. A possible example was that solutions were made up inaccurately, or not made to the precise concentration of 1M. In addition, as the experiment was done in a class room there were constant alterations in the light intensity, temperature, pressure and chemicals (such as oxygen) in the atmosphere resulting in an increase or decrease in chemical reactions, therefore it was difficult to make this experiment completely accurate. Thus, in order to improve this factor the experiment could be performed in a vacuum, or under calculated standard conditions a pressure of 100kPa, a temperature of 298K (25oC), and by using solutions of c oncentration 1 mol dm-3.

Free Essays on Job

This book of the Bible is about Job, a God fearing man who was righteous and wealthy. Job was born in Uz and was blameless and upright. He has seven sons and three daughters and had many sheep, oxen, and camels. He was the wealthiest and greatest man in the entire East. One day Satan wanted to test Job to see how faithful he was, so God agreed and told Satan he may not lay a finger on Job himself. One day while Job was at his house, a messenger came and told him that many of his servants had been killed and thieves carried off his oxen and donkeys. Then another came and informed him that his sheep and servants were burned in a fire from the sky and his camels were swept off by raiders. Then the last messenger came and told him that while his sons and daughters were feasting a mighty wind came upon the house and it crashed upon them. Nevertheless, Job, being a God serving man, tore his robe and proclaimed â€Å"Naked I came from my mother’s womb, and naked I will depart. The Lord gave and the Lord taken away, may the name of the Lord be praised† (Job 1:21) and in this. Job did not sin or turn from God. On another day, Satan came to God and said â€Å"Skin for skin! A man will give all he has for his own life†¦Ã¢â‚¬  (Job 1:2, 4) .So God agreed and told Satan he may do anything but take Jobs life. Therefore, Satan inflicted Job with sores and boils from his feet to his head. After seeing the sores, and the pain Job was going through, his wife pleaded with him to just curse God and die. Job replied, â€Å"You are talking like a foolish woman. Shall we accept good from God, and not trouble?† (Job 2:10). Therefore, Job did not sin, and did not turn his back on God. In the next few chapters of Job, we see some of the greatest poetry ever written. Job is seen in utter despair and asks God why he is being punished. We see Job asking what many people today ask when they suffer. He speaks with his friends about his pains and why he is being punis...

My first thought was that Satan had won the wager, by Job questioning God. Which he does question God but all he wanted to know was the answer to the question. Job wanted to know why he was put into the circumstances that he was in when he knew he had done nothing wrong. He knew that he was a righteous man and by him knowing that he did not understand why he was put into those circumstances, so he wanted an answer from God. Now you may think that Satan won but God was the one who won the wager. My first argument is based on the fact that throughout the whole book of Job, he does not curse God. That was the main purpose of the wager, Satan bet God that his humble servant would curse him if he would take everything away from him and also take his health. Through all that, Job knew to never curse God. Especially in the part of the book where Job’s wife tells him to curse God and Job says no. He then told his wife that you need to take the good and the bad that God gives you. All Job wanted to know was why was this done to him, so he was questioning God and his authority. Throughout the story no one can help Job in figuring out what the answer is to the question that he wants answered. The comforters try to talk to him but it does not work, they do not answer the question for Job. Job knows that he has done nothing wrong to deserve these circumstances that he has been put in. Who would think that this man would not curse God after what God puts him through. An y other man would curse without even thinking about it. That is why Job is a righteous man and he is the humble servant of God. Well God knows that and that is why he picked Job. Elihu trys to tell Job that he adds rebellion to his sin but Job knows that he has not sinned. Well in those times they only understood that if you were punished in some way that you must have sinned. So Job is not happy with what Elihu is telling him about why this is being ...

Organization and religion Essay Example | Topics and Well Written Essays - 500 words

Organization and religion - Essay Example ligion have been the result of an effective organization/or ineffective management.1 Naturally, one cannot blame organization and cohesion upon all the different branches of religion that exist; however, understanding the role that organization plays in defining and effectively constraining the responses and approaches of believers goes a very long way in helping the individual to understand the powerful and dynamic role that organization has within religion. A secondary way through which organization can be seen as having a powerful impact upon religion is with regards to doctrine. For instance, considering the case of Islam, core doctrines stipulate the attitudes and behavior that proper Muslims should exhibit to one another and to the outside world. In a matter speaking, the organizational constraints that are oftentimes adopted by religious organizations have to do with the risen or canonical laws that are the result of a particular holy book, relics, or prophecy. In such a way, these written approaches oftentimes are uniquely similar to the way in which a business entity operates under a set of guidelines and standard operating procedures. Without these procedures and guidelines, the business would not have a grounding or anchor with respect to the way in which to engage and understand the situations that present themselves within the day-to-day interactions that take place. Similarly, without a level of doctrine and written belief that creates a distinct aspects of cohesion within the believing communities, religious organizations would lack the same qualities that have been previously described with respect to the business world. From the information that is thus far been engaged, it is clear and apparent that organization plays a prominent and extraordinarily important role with respect to the way in which religious conviction and practice is carried out.2 Although this has only been analyzed with respect to the major world religions of Islam and
