...Title: Experimental Applications of Hess’s Law Objectives: 1) To study and understand the experimental method of Hess’s law. 2) To interpret experimental data by applying Hess’s law. 3) To determine the H of ammonium chloride solid to ammonia gas and hydrochloric acid gas by using Hess’s law. Introduction: A reaction that release heat to surrounding is known as exothermic reaction. It is usually observed as temperature increases in solvent, container and other immediate surroundings. The expression of heat released from the reaction is: qreaction = qsolution + qcalorimeter ……..(1) The qcalorimeter is nearly zero because the calorimeter in this experiment is assumed to absorb little heat. So, the equation is simplified to qreaction = qsolution ……...(2) The change in temperature that caused by the addition of a given amount of heat will depend on specific heat, Csp of substance. Therefore, the heat involved is calculated by the equation Q = (Csp)(m)(T) ………(3) Mass of substance is m, change is temperature is T (final temperature – initial temperature). The heat changes observed is equal to enthalpies of reaction, H for the reactions considered because this experiment was run at constant pressure. The enthalpy of these directly observed reactions and Hess’s law was used to calculate the enthalpy change for an additional reaction which is not directly observed. Hess’s law stated that the overall enthalpy...

...dissertation: A CORRELLATlONAL STUDY IN LEADERSHIP STYLE AND USE-OF-FORCE BEHAVIOR OF POLICE OFFICERS Commiittee: Orlando Ramos, PhD, Chair Peggy Coplin, DPA, Committee Member Jack Phan, PhD, Committee Member ,,__.____ _ ,,__.____ _ Jeremy Moreland, PhD Dean, School of Advanced Studies University of Phoenix ABSTRACT Leadership style and police officer use-of-force are two important functions of law enforcement. What could be more important in a law enforcement agency than to have these two variables coexisting in an organization in a harmonious manner? By investigating whether a relationship exists between these two variables an answer to this question could emerge. In law enforcement today, the cost associated with excessive use-of-force civil law-suits against police officers and their departments can be staggering. Exposing police officers to a specific leadership style may influence the dynamics in the use-of-force behavior during arrests or other police actions. Evaluating a non-experimental ex post facto field scenario and comparing these results with perceived leadership styles of the supervisors was a primary function of this study. Results from using the Multifactor Leadership questionnaire; both Rater and Leader forms were used to gather additional information. Fifteen officers participated in the role play...

Stephen Porter* and Leanne ten Brinke University of British Columbia Okanagan, Kelowna, British Columbia, Canada In this paper, we provide our view of the current understanding of high-stakes lies often occurring in forensic contexts. We underscore the importance of avoiding widespread pitfalls of deception detection and challenging prevailing assumptions concerning strategies for catching liars. The promise and limitations of each of non-verbal/body language, facial, verbal/linguistic, and physiological channels in detecting deception are discussed. In observing the absence of a single cue or behavioural channel that consistently reveals deception, a holistic approach with concurrent attention to multiple channels of a target’s behaviour (ideally videotaped for review) and changes from baseline behaviour is recommended whenever possible. Among the best-validated cues to be considered together include: illustrators, blink and pause rate, speech rate, vague descriptions, repeated details, contextual embedding, reproduction of conversations, and emotional ‘leakage’ in the face.

Copyright © 2007 by Pearson Education, Inc. 2 Chapter 1 Have you ever wondered how we see or how we remember things? Have you ever contemplated the strange nature of attention? I didn’t think so. Most of the people I know do contemplate how the mind works, but only when their mind lets them down. They contemplate memory (“Why can’t I find my keys?”), attention (“I want to find my keys, so why can’t I concentrate?”), and vision (“How could I not see my keys when they were right in front of me the whole time?”). Questions such as “How does vision work?” seem somewhat interesting, but no more interesting than thousands of other questions. It’s like someone asking you whether you want to know about the history of guitar making. “I don’t know; maybe. Is it interesting?” Truthfully, “How...

It visualizes the negation of female gender in art. The paper investigates the dichotomy of language, the use of irony and situational metaphors to displace conventional ones; it blends theories with critical evaluation of discourse. The research uses empirical methods in solving hypothetical questions with the use of extensive and relatively unstructured interviews. It examines the interviews of twenty five people independently, these people include: University lecturers, students, administrative and technical staff. The work analyzes concurrently their interview testimonies to search for congruence. Data analysis begins with a detailed microanalysis in which emergent concepts...

In this paper, I also utilized the concept of corporate social responsibility as well as the triple bottom line in order to form my own model of sustainability. This model is used to analyze the case of the 2010 Gulf of Mexico oil spills which was claimed as the responsibility of British Petroleum. I also addressed the strong relationship between organizational justice and organization sustainability with the conclusion that by enhancing organizational justice and fairness, organizations will be able to obtain its sustainable development in the long terms.

Hence, the relevant conceptual, theoretical, and empirical work is reviewed, drawing upon correlational, experimental, and qualitative findings. A meta-analysis of procrastination’s possible causes and effects, based on 691 correlations, reveals that neuroticism, rebelliousness, and sensation seeking show only a weak connection. Strong and consistent predictors of procrastination were task aversiveness, task delay, selfefficacy, and impulsiveness, as well as conscientiousness and its facets of self-control, distractibility, organization, and achievement motivation. These effects prove consistent with temporal motivation theory, an integrative hybrid of expectancy theory and hyperbolic discounting. Continued research into procrastination should not be delayed, especially because its prevalence appears to be growing. Keywords: procrastination, irrational delay, pathological decision making, meta-analysis Procrastination is extremely prevalent. Although virtually all of us have at least dallied with dallying, some have made it a way of life. Estimates indicate...

...Standard 1: A school administrator is an educational leader who promotes the success of all students by facilitating the development, articulation, implementation, and stewardship of a vision of learning that is shared and supported by the school community. The effective administrator: 1.1 Uses research about best professional practice. Cooperative Learning "Cooperative learning is the instructional use of small groups so that students work together to maximize their own and each other's learning." WHAT IS IT? Cooperative learning is a successful teaching strategy in which small teams, each with students of different levels of ability, use a variety of learning activities to improve their understanding of a subject. Each member of a team is responsible not only for learning what is taught but also for helping teammates learn, thus creating an atmosphere of achievement. WHY USE IT? Documented results include improved academic achievement, improved behavior and attendance, increased self-confidence and motivation, and increased liking of school and classmates. Cooperative learning is also relatively easy to implement and is inexpensive. HOW DOES IT WORK? Here are some typical strategies that can be used with any subject, in almost any grade, and without a special curriculum: Group Investigations are structured to emphasize higher-order thinking skills such as analysis and evaluation. Students work to produce a group project, which they may have a hand...
