A Political, Cultural, and Religious Description of the Current Atmosphere as Exists in Israel Israel, in the 1990s, is in a continual state of political, cultural and religious flux. Religion continues to play a central factor in the difficulties which the state has been and continues to experience. This unique country is characterized by an amalgam of cultural and ethnic diversity. This historical and cultural fact ensures that the difficulties the state has been experiencing in realizing self-adjustment will continue. At the same time, there exist mostly positive and persistent facets of the culture which continue unabated as will be discussed.Ã¢â¬ ¦show more contentÃ¢â¬ ¦Recently, hundreds of thousands of Jews from the former Soviet Union and other Eastern European countries, as well as most members of the ancient Jewish community of Ethiopia, have arrived to make their homes in Israel. Th roughout the years, groups, families and individuals have chosen to come from all parts of the free world, in greater or lesser numbers, to take part in building the country. With a population which has increased more than seven-fold since 1948, and with people still coming from all over the world bringing varied languages, traditions, educational standards, and social outlooks, Israel continues to seek ways to meet the challenge of developing a modern, democratic society. In a certain sense, Israel is not unlike the United States of America, in that it is a land which is comprised of many people from varied backgrounds. It is both urban and rural where some 89.9% of the land is made up of cities and the remaining rural area is comprised of villages, Kibbutzim, and Moshavim. Moshav or Kibbutz comprises about 10% of the population in rural areas and agricultural settlements. The Kibbutz is a social and economic unit (property and means of conduction are communally owned) in which dec isions are made by the General Assembly of its members. Meals, prepared in a central kitchen, are served in a communal dining hall. Clothing and linens are washed, mended and distributed by a central laundry; and children grow up together in organizedShow MoreRelatedAn Analysis of Terrorism Essay9824 Words Ã |Ã 40 PagesTerrorism is also viewed as a political act against a government and itÃ¢â¬â¢s citizenry, secondly, it is viewed as a coercive means to change some policy through the application of violence upon society .

Giovanni Gomez Tammy Jonhson English 2 B 14 November 2014 Euthanasia: Assisted suicide Which is better - suffering, pain, and holding onto life for a period of time or just being laid to rest in peace? Nine out of ten people would pick the latter (Georgia State University) if just asked that question without a scenario, but when given the scenario and thinking about their family they might change their opinion. Euthanasia is related to this because it is the destruction of life, and in todayÃ¢â¬â¢s society, medications can help with pain and suicide is typical due to the amount suffering for depression. Therefore, there is no reason why euthanasia should be illegal at this point.

Ask yourself what kind of life is that, would you want to be in this role for the rest of your life? In light of this, these kind of living arrangements can put great strain on a family and love ones. With the legalization of euthanasia, this can act of a relief to some families and the patient.

Review of literature The literature on employee engagement builds on earlier research and discussion on issues of commitment and organizational citizenship behavior (OCB), but means more than what these terms encapsulate. The defining distinction is that employee engagement is a two-way interaction between the employee and the employer, whereas the earlier focus tended to view the issues from only the employeeÃ¢â¬â¢s point of view. Definitions of engagement ,or characteristics of an engaged workforce, focus on motivation, satisfaction ,commitment , finding meaning at work, pride and advocacy of the organization (in terms of advocating/recommending either the products or services of the organization, or as a place to work ). additionally , having some connection to the organizationÃ¢â¬â¢s overall strategy and objectives and both wanting and being able to work to achieve them, are key elements of engagement. A recurring theme in the literature is the idea that engagement involves workers Ã¢â¬Ëgoing the extra mileÃ¢â¬â¢ , and exerting discretionary effort over what is normally expected. We will write a custom essay sample on Influence of Organizational Culture on Employee Engagement or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page An organizationÃ¢â¬â¢s productivity is measured not in terms of employee satisfaction but in terms of employee engagement . employees are said to be engaged when they show a positive attitude towards the engagement and express a commitment to remain with the organization. It is the level of commitment and involvement an employee has towards the organization and its values. An engaged employee is aware of the business context and works with colleagues to improve performance within the job for the benefit of the organization. Employee engagement 1. csikszentmihalyi (1975) studied the effect of engagement in organizational behavior is the notion of flow. He defines Ã¢â¬ËflowÃ¢â¬â¢ as the holistic sensation that people feel when they act with total involvement. Flow ii the state in which there is little distinction between the self and environment . when individuals are in flow state little conscious control is necessary for their actions. Employee engagement is thus the level of commitment and involvement an employee has towards their organization and its value. The organization must work to develop and nurture engagement which requires a two way relationship between employer and employee. Thus employee engagement is a barometer that determines the association of a person with the organization. 2. khan (1990) studied the effect of Engagement at work where as the engagement people employ and express themselves physically, cognitively and emotionally during role performances. He described employee engagement in his psychological literature as different from other employee role constructs such as job involvement , commitment or intrinsic motivation, asserting that it focused on how psychological experiences of work shape the process of people presenting and absenting themselves during task performances. Khan argued that engagement was a multidimensional construct in that employees could be emotionally, cognitively or physically engaged. For psychological engagement and organizational behaviors, the two major dimensions were emotional and cognitive engagement . mployees could be engaged on one dimension and not the other. The more engaged an employee was on each dimension, the higher his/her overall personal engagement. Khan asserted that employees experienced dimensions of personal engagement or disengagement during daily tasks. Engagement occurred when one was cognitively vigilant and/or emotionally connected to others. Disengaged employees uncoupled them selves from roles and withdrew cognitively and emotionally. They displayed incomplete role performances and were effortless, automatic or robotic. 3. Gallup (1999) study consist on more than 30 years of in-depth behavioral economic research involving more than 17 million employees. This research has appeared in prestigious business and scientific publications, including the journal of Applied Psychology and Harvard Business Review; first, break all the rules and 12: The Elements of Great Managing. Through rigorous research, they have identified 12 core elements Ã¢â¬â the Q12 Ã¢â¬â that link powerfully to key business outcomes. These 12 statement emerged as those that best predict employee and workgroup performance. GallupÃ¢â¬â¢s latest meta-analysis (an analysis of data from more than 152 organizations) shows dramatic differences between top- and bottom Ã¢â¬âquartile workgroups on key business outcomes. Beyond the significant differences engaged workgroups show in productivity, profitability, safety incidents , and absenteeism versus disengaged workgroups we have proven that engaged organizations have 3. 9 times the earnings per share (EPS) growth rate compared to organizations with lower engagement in their same industry. The Gallup great workplace Awards was create to recognize companies with an extraordinary ability to create a engaged workplace culture . organizations can apply each year for this award based on the criteria such as organization size , minimum response rate and minimum results. 4. Aaron Sorensen in Perspectives (2007) examined the prediction of engagement, describe a methodology for measured it and share an approach for using engagement data to make workforce investments that ultimately increased productivity and derived business results. It draws on information collected as part of Sibsons 2006 Rewards of WorkSM (ROW) Study of over 1,200 American workers1, and provides important insights into the drivers of engagement and how organizations might improve engagement levels in ways that bring a significant return on investment. 5. Medlin, W Green (2009) investigated the relationships among goal setting, employee engagement, workplace optimism, and individual performance constructs. Goal setting is hypothesized as positively impacting employee engagement, employee engagement as positively impacting workplace optimism, and workplace optimism as positively impacting individual performance. Design/methodology/approach Data collected from a sample of 426 full- and part-time employees are analyzed following a structural equation modeling methodology. Findings The measurement and structural models fit the data relatively well. Goal setting positively impacts employee engagement, employee engagement positively optimism . Youssef Luthans (2007) examined the effects of hope, optimism, and resilience had in the workplace on 40 employeesÃ¢â¬â¢ job performance, job satisfaction, work happiness, and organizational commitment. Hope and resilience had a more direct affect on organizational commitment whereas hope had a greater impact on performance. Hope allows employees to be better at created more realistic plans for completed task so as not to focus on the failure that accompanies an incomplete task. Optimism strengthens the employeeÃ¢â¬â¢s resilience to break through barriers and causes the employee to build social support and other strengths to overcome obstacle he or she may encounter. 2. Arakawa and Greenberg(2007) investigated whether teams are more engaged and productive when led by an optimistic manager. Furthermore, they hypothesised that optimistic managers embody positive leadership-employing a strengths-based approach, maintaining a positive perspective, and frequently providing recognition and encouragement-which increases the engagement and productivity of their employees. The study used a cross-sectional survey design at two time points. The researchers developed a survey to measure this concept of positive leadership. In addition, two measures were used: the Life Orientation Test Revised (LOT-R) to measure optimism and the Gallup Organizations Q? to measure engagement. In a cross-sectional study of 86 employees and 17 managers in an Information Technology (IT) organization, positive leadership correlated with employee optimism, engagement, and project performance. When we looked at a subset of this data prospectively, with 39 employees and 14 managers, manager optimism predicted project performance. Our data support the claim that positive leadership is correlated with employee engagement and performance, and further extends the importance of optimism in the workplace. Coaching implications are also discussed, in terms of exploring how coaching psychologists can work with executives to develop their managerial style. 3. Medlin, Green (2009) investigated the relationships among goal setting, employee engagement, workplace optimism, and individual performance constructs. Goal setting is hypothesized as positively impacting employee engagement, employee engagement as positively impacting workplace optimism, and workplace optimism as positively impacting individual performance. Data collected from a sample of 426 full- and part-time employees are analyzed following a structural equation modeling methodology. The measurement and structural models fit the data relatively well. Goal setting positively impacts employee engagement, employee engagement positively impacts optimism, and optimism positively impacts individual performance, as hypothesized. Research limitations/implications Although data are collected from a relatively diverse group of respondents, the ability to generalize the findings is limited because the results are derived from a non-random sample. All measures are based on the perceptions of the respondents. Job performance is reported by each respondent may not reflect the supervisors performance rating and is not necessarily consistent with objective performance indicators such as sales generated by a marketing employee. Practical implications Results indicate that formal, structured goal setting processes lead to higher levels of employee engagement, that higher levels of engagement lead to improved workplace optimism, and that improved optimism in turn leads to higher levels of individual performance. Originality/value The paper provides empirical support for the implementation of management programs that foster goal setting, employee engagement, and workplace optimism for the purpose of enhancing the performance levels of individual employees. 4. Geers , Lassiter and Wellman (2009) this study is to investigated the circumstances under which a personality variable, namely dispositional optimism, is associated with successful goal engagement and attainment. Dispositional optimism refers to a generalized positive outcome expectancy (Scheier Carver, 1985). A great deal of research on dispositional optimism stems from the behavioral self-regulation model (Carver Scheier , 1981, 1998), which proposes that goal-directed action is guided by a series of negative feedback loops.

Lab Report Final Draft Essays Lab Report Final Draft Paper Lab Report Final Draft Paper The student conducted the experiment given, using safe lab practices, that found the polarity of two separate solvents, and it has been shown through experimental exults that the hypothesis formed in the beginning of this experiment is true. It has been deducted from this experiment that solvents which dissolve, or pick-up, water soluble inks are polar, while solvents that dissolve, or pick-up, non water soluble inks are non-polar. Introduction In order to determine the polarity of two solvents, slime and silly putty, an experiment is being conducted that will provide data to formulate a conclusion on the matter. This lab will answer whether or not the tested solvents are polar or non-polar, as well as whether the inks used are polar or non-polar. Information was given in the beginning of the lab explaining that only polar solvents will dissolve or pick-up polar ink, and only non-polar solvents will dissolve or pick-up non-polar solvents. Chromatography will be used to verify conclusions made on the polarity of the inks. Background The lab provided information as the basis for the experiment. It was provided that polar solvents only pick-up or dissolve polar substances, as well as that monopole solvents only pick-up or dissolve monopole substances. Also, in the lab introduction, the information examines covalent and ionic bonds teaching that he polarity characteristics of substances are due to their atomic structure and molecular shape. For example: Water is a polar molecule due to the electrons being shared between the oxygen atom and the two hydrogen atoms. As the electrons are pulled close to the oxygen atom it leaves a slightly positive charge on the outside of the hydrogen atoms, while the other side of the molecule contains a slightly negative charge. The knowledge of the polarity of water is a control within this experiment. Objective Using the knowledge of polar and non-polar molecules, we can observe the heartsickness of the effects of the experiment on the inks, and determine the polarity of the solvents. Hypothesis Knowing the composition of the Slime being mainly water, the slime will dissolve or pick-up the water soluble inks and the silly putty will pick up the non-water soluble inks. Materials and Methods Materials: (1) 250 ml Beaker 5 ml 4% Borax Solution Dry Erase Marker (1) 10 ml Graduated Cylinder (1) 100 ml Graduated Cylinder Filter Paper (Disk) Filter Paper (Square) 0. G Guar Gum Highlighter Permanent Marker 1 Popsicle Stick Silly Putty Ruler Wooden Stir Stick [emailprotected] Roller Pen Distilled Water Newspaper Notebook Paper Scissors Part 1: Making Slime 1. Weigh out 0. 5 g of guar gum into a 250 ml beaker. 2. Measure 50. 0 ml of distilled water into a 100 ml graduated cylinder and pour it into the 250 ml beaker that contains the guar gum. 3. Rapidly stir the mixture with a wooden stir s tick for three minutes, or until the guar gum is dissolved. 4. Measure 4. 00 ml of a 4% Borax solution into a 10 ml graduated cylinder and add it to the guar gum and water. . Stir the solution until it becomes slime. This will take a few minutes. If the slime remains too runny, add an additional 1. Ml of the 4. 0% Borax solution and continue to stir until the slime is the slightly runny or gooey. 6. Once you are satisfied with the slime, pour it into your hands. Be sure not to drop any of it on to the floor. 7. Manipulate the slime in your hands. Write down observations made about how slime pours, stretches, breaks, etc. In Part 1 of the Data section. CAUTION: Slime is slippery and if dropped it can make the work area slick. . Place the slime back into the beaker and WASH YOUR HANDS. Part 2: Slime and Putty Ink Tests 1 . On a piece of notebook paper make one 20 25 mm long mark of each of the inks you are testing (permanent marker, highlighter, Dry Erase, and [emailprotected] Roller Pen). Space the marks at least one inch apart. Use a pencil to label each mark with its description. A. Water soluble inks include those in highlighters and certain pens. B. Water insoluble inks include those in a permanent pen/markers, newsprint, and a dry-erase markers. 2. While the inks are drying, select a passage or a picture in the newspaper to test with the slime. 3. Develop a hypothesis stating whether or not you believe the slime produced in Part 1 will pick up newsprint ink. Record this hypothesis in the Post-Lab Questions section. Then, break off a small piece of slime that is 3 5 CM in diameter. Gently place this piece on top of the newspaper print, then carefully pick it up again. 4. Observe and record in Table 1 whether or not the ink was picked up onto the slime. 5. Break off another small piece of slime. Once the inks from Step 1 have dried gently place the slime on top of the first spot on the notebook paper, then carefully pick it up. Repeat this for each of the inks. Observe and record which inks were picked up (dissolved) by the slime in Table 1. 6. Repeat this ink testing two more times for accuracy. 7. Hypothesize which inks the silly putty will pick up in the Part 2 of the Data section. Then, perform the ink tests with the Silly [emailprotected] according to the procedure outlined in Steps 5 6. Part 3: Chromatography of Ink Samples 1. Use a pencil or scissors to poke a small hole in the center off piece of filter paper (see Figure 7). 2. Spot the filter paper evenly spaced approximately 2 CM from the small hole with the two insoluble inks and the two soluble inks that were used in Part 2, Step 1. 3. Obtain a h piece of filter paper. Fold the paper in half several times so that it makes a narrow wick. . Insert the wick into the hole of the spotted paper so that it is above the top of the filter paper by approximately 2 CM. 5. Fill a 250 ml beaker 3/4 full with water. 6. Set the filter paper on top of the beaker so that the bottom of the wick is in the water. The paper should hang over the edge of the beaker with the spotted side up. 7. Allow water to travel until it is approximately 1 CM from the edge of the filter paper. Remove the filter paper from the beaker. 8. Observe which inks moved from where they were originally spotted. Record your observations in Part 3 of the Data section. In the experiment, we were given the above instructions on how to create slime. Silly putty was provided in the lab kit. A 25 CM mark was made on notebook paper using four types of ink: highlighter ink, nun-ball roller pen ink, permanent sharpie ink, and dry erase marker ink. There was also a newspaper clip used to test the solvents on the newspaper ink as well forming the total of 5 experimental groups. The inks are the dependent variables in this experiment. The solvents were then placed on each of the five inks, three times each, to see if they picked-up or dissolved the inks. The solvents are the independent variables n this experiment. The result of whether the solvent picked or dissolved the ink was recorded. After completing this part of the test, filter paper was placed on top of a beaker filled % full with water, with a wick placed through the filter paper into the water. Dots of the four individual inks were placed on the filter paper. The reactions of the inks, as the water traveled up the wick into the filter paper were recorded. The experiment can be explored further in the above experiment procedural steps.

The silly putty picked-up, or dissolved, both the dry erase marker ink, and the newspaper ink. The slime picked-up, or dissolved, the highlighter and unable roller pen ink. Neither the silly putty, nor the slime, picked-up or dissolved the permanent marker ink. When the ink was placed on the filter paper and water was placed in the beaker as the solvent, the highlighter and the roller pen ink were both dissolved and pulled toward the wick. The permanent marker and the dry erase marker both ere unaffected by the water. Discussion, Data Interpretation, and Experimental Conclusions Seeing the results in the tables above shows the polarity of both the inks and the solvents used. Water is a polar molecule which supports the results of the chromatography as well. The information of the water solubility of the inks used was given in the beginning of this experiment, and the information was verified by the chromatography, which showed the inks that dissolved in water. Both the highlighter and the roller pen were soluble inks. Knowing this, and in knowing the properties of water, means they are, in fact polar. After seeing the slime dissolve and pick-up traces of both of these inks, it can be concluded that the slime is polar as well. The newspaper ink, permanent marker, and dry erase marker were insoluble inks. The newspaper ink was not verified by chromatography, however, both the permanent marker ink, and the dry erase marker were; they did not move across the filter paper when water was added. In seeing that the silly putty picked up the dry erase marker ink, and the newspaper ink, it can be concluded that the silly putty is a non-polar solvent. Error was found in my experiment in seeing that the non-polar solvent did not solve or pick-up the permanent marker.

Boil Water at Room Temperature You can boil water at room temperature without heating it. This is because boiling is about pressure, not just temperature. Heres an easy way to see this for yourself. Simple Materials watersyringe You can get a syringe at any pharmacy or lab. You dont need the needle, so itsÃ safe project, even for kids. How to Boil Water Without Heating It Use the plunger to pull up a bit of water into the syringe. Dont fill it you need airspace in order for this to work. You just need enough water that you can observe it.Next, you need to seal the bottom of the syringe so that it wont be able to suck up more air or water. You can put your fingertip over the opening, seal it with a cap (if one came with the syringe), or press a piece of plastic against the hole.Now youll boil the water. All you need to do is pull back as quickly as you can on the syringe plunger. It may take a couple of tries to perfect the technique, so you can keep the syringe still enough to watch the water. See it boil? How It Works The boiling point of water or any other liquid depends on vapor pressure. As you lower the pressure, the boiling point of the water drops. You can see this if you compare the boiling point of water at sea level with the boiling point of water on a mountain. The water on the mountain boils at a lower temperature, which is why you see high-altitude instructions on baking recipes! When you pull back on the plunger, you increase the amount of volume inside the syringe. However, the contents of the syringe cant change because you have sealed it. The air inside the tube acts as gases do and the molecules spread out to fill the whole space. The atmospheric pressure inside the syringe drops, creating a partial vacuum. The vapor pressure of the water becomes high enough compared to the atmospheric pressure that the water molecules can easily pass from the liquid phase into the vapor phase. This is boiling. Compare it with the normal boiling point of water. Pretty cool. Any time you lower the pressure around a liquid, you lower its boiling point. If you increase the pressure, you raise the boiling point. The relationship is not linear, so you would need to consult a phase diagram to predict how great the effect of a pressure change would be.

(DNRC) - Essay Example Risk assessment procedures comprise of identifying, assessment of the threat impact, and approval of measures to lessen the risk. Additionally, risk mitigation comprises of prioritizing, upholding, and executing the suitable risk-reducing controls endorsed by the risk assessment. Finally, evaluation and assessment puts emphasis on the frequent assessment process and the important factors for an effective risk management program. Therefore, the purpose of this report is to offer practical guidance on the security and public safety committee of the DNRC on assessing risks through examining these issues and detailing the opportunities and benefits available to the organizations that embrace and implement the risk assessments to their business processes. Therefore, the Security and Public Safety Subcommittee of DNRC was headed by the Samantha Salerno who is in the United States secret service, and the sub-ordinates were Felicia Fontaine, ASAC FBI Miami, Melanie Duncan, Director Miami-Dade Police Department, Gregory Jameson, SAC ATF Miami, Robert Waters, Director Miami-Dade Fire-Rescue Department, Jean-Louis Joseph, Chief Miami Police Department, and Geoff Goldman, Chief, Miami Beach Police Department (DRNC). The aim of this committee is to ensure that it looks at the culture of the organization, the stakeholders, and the levels of vulnerability and risks of the seven critical infrastructure assets to come up with an effective risk management program. This is because the analysis will be used to manage the risks of DNRCÃ¢â¬â¢s critical infrastructure assets effectively and go a long way in assisting them to find out how the allocated resources will be used in the best way possible leading up to the present and future events. The co mmunication, external and internal environment, culture and the overall risks of the critical infrastructure
