The study was influenced by Everett Rogers's Diffusion of Innovation theory. The mixed-method research was conducted using specialEducation teachers within the State of Indiana. A sample of 164 specialEducation teachers responded to the quantitative survey. Each subject completed a 28 question …

Killing In Combat And World Assumptions, Jennifer Mcdonner

All-Inclusive List of Electronic Theses and Dissertations

The current research was qualitative in nature, exploring the experience of having killed in combat from a constructivist and phenomenological framework. The researcher used semi-structured interviews to examine the lived experiences of U.S. soldiers who have killed in combat and how those experiences relate to fundamental assumptions such as benevolence of the world, meaningfulness of the world, and inherent self worth as proposed by Janoff-Bulman. Participants were four men and one woman who served in Operation Iraqi Freedom. The researcher identified thematic networks of the evolving self, the self in relation to others, and the impermanence of the environment as …

Beyond Content, Deeper Than Delivery: What Critique Feedback Reveals About Communication Expectations In Design Education, Deanna Dannels, Amy Housley Gaffney, Kelly Norris Martin

International Journal for the Scholarship of Teaching & Learning

In design education, the critique is a communication event in which students present their design and critics provide feedback. Presumably, the feedback gives the students information about their progress on the design. Yet critic feedback also serves a socializing function—providing students information about what it means to communicate well in the design education context. Using a qualitative research methodology, this study explores what critic feedback reflects about expected communication competencies in design studios. Results suggest that communication competence in this setting involves interaction management, demonstration of design evolution, transparent advocacy of intent, explanation of visuals, and the staging of the …

Performance Of Privatised And Private Firms : Empirical Evidence From Egypt, Mohamed Bahaa El Din Mohamed M. M. Bekheit

Plymouth Business School Theses

Privatisation has been a major political and economic phenomenon over the past few decades, and researchers continue to target it for both theoretical and empirical work. The objective of this thesis is to evaluate the Egyptian experiment concerning its privatisation programme, and to determine whether this programme has affected the performance of privatised firms. Using 15 years of data, which cover the period 1990/1991 to 2004/2005; this thesis empirically investigates three main issues. Firstly, it examines whether the performance of privatised firms improves following privatisation through comparing pre- and postprivatisation performance in terms of profitability, operating efficiency, output, leverage and …

Electrocatalytic Oxidation Of D-Glucose Using A Cd Ad-Atom-Modified Au(111) Electrode In Alkaline Solution, Zekerya Dursun, Sami Ben Aoun, Isao Taniguchi

Turkish Journal of Chemistry

Au(111) single crystal electrodes were modified by underpotential deposition (UPD) of Cd ad-atoms with different coverages, which were used for the electrocatalytic oxidation of glucose in alkaline media. The catalytic activity of the electrodes was dependent on how the Cd ad-atoms covered the surface. Under the presented experimental conditions the monolayer (ML) Cd ad-atom-covered Au(111) electrode had the best catalytic activity on D-glucose oxidation, in terms of both potential shifts and peak current increases, as compared to the 0.11, 0.5, and 2 ML covered and bare Au(111) electrodes. Double layer capacity measurements revealed that the shifts of the potential of …

Mefenamic acid reacts with cobalt(II) ions in aqueous alkaline medium to form a highly stable deep brown complex at ambient temperature. The complexation process was optimized in terms of pH, temperature, agitation rate, and contact time using classical studies. A response surface method based on Box-Behnken design was used to statistically model the complexation reaction and investigate factor effects along with their interactions. A quadratic model was developed using experimental data with a correlation coefficient of 0.9609. Numerical optimization was performed to achieve the optimum solutions of factor combinations. The results of the classical investigation and statistical method were in …

Potentiometric Determination Of The Stability Constants Of Lanthanide Complexes With Iminodiacetic Acid In Water And Dioxane-Water Mixtures, Sevgi̇ Arzik, Ebru Mavi̇oğlu Ayan, A. Sedat Çelebi̇

Turkish Journal of Chemistry

The protonation constants of iminodiacetic acid (H_2 ida) and the stability constants of its complexes with Nd(III), Sm(III), Gd(III), Dy(III), and Er(III) ions at metal/ligand mole ratios of 1:1, 1:2, and 1:3 at 25 °C and 0.1 M ionic strength in aqueous medium and 20%, 45%, and 70% w/w dioxane-water mixtures were determined by the potentiometric method using the BEST computer program. The stability constants of the complexes that formed increased as the dioxane content increased. The stability of all the analogues' complexes, both in aqueous medium and in dioxane-water mixtures, were in the order of Nd(III) < Sm(III) < Gd(III) < Dy(III) < Er(III).

The research was motivated by the writers desire to find ways to be in communication with youth and provide pastoral care to them during their adolescent years. The thesis will explore computer mediated communication and its usefulness in providing pastoral care to youth by exploring the benefits and limitations, how it can be abused, namely cyber bullying, how it can provide an opportunity for mentoring and a theological reflection on how it can …

Opportunity, Tools And Support: Ngo Engagement In The Security And Disarmament Field, Sarah Estabrooks

Theses and Dissertations (Comprehensive)

NGOs have been consistently excluded from multilateral proceedings in the security and disarmament sector where states are concerned about their national security interests. And yet, they have found avenues to participate in the multilateral process through the negotiation of treaties, provision of expert research and testimony, systematic monitoring of state compliance, documentation of UN proceedings, and even as members of government delegations. This paper explores the conditions that enable NGOs to engage directly in the state-centric system of the United Nations, addressing political opportunity, enabling resources, and institutional support. I explore how NGOs contribute to international politics, using a constructivist …

The “Both-And” Choice: The Impact Of Informational, Motivational And Behavioural Skill Messages On Adolescent Dual Protection, Tyla Fullerton

Theses and Dissertations (Comprehensive)

The promotion of simultaneous condom and hormonal contraceptive use is an imperative given increasing rates of sexually transmitted infections and patterns of sexual behaviour in Canada. Previous research has shown that few adolescents engage in dual protection due to a number of barriers including attitudes and beliefs about sexual health risk. These attitudes and beliefs are shaped by key sexual health referents including parents, friends, educators, health care providers, and sexual partners. This study investigated how these sources influence information, motivation and behavioural skills (IMB) that lead to dual protection. Attitudes and beliefs are shaped by information and motivation from …

Multi-Method Assessment Of Newcomer Settlement Experiences In Kitchener-Waterloo, Qaseem Ludin

Theses and Dissertations (Comprehensive)

Every day hundreds of newcomers begin a new life in Canada. Some are refugees fleeing persecution, others come to join family, and yet others (mostly the economic and independent categories) are seeking to make a better life for themselves. In all, since 2000 around 250,000 people have settled in Canada each year. Their backgrounds and personal histories may be widely different and each one’s experience on arrival is unique. The communities across Canada into which they integrate differ too in their character and in the manner in which they receive newcomers. For many new Canadians, there are, nevertheless, certain shared …

Humanitarian Assistance And The Private Security Debate: An International Humanitarian Law Perspective, Benjamin Perrin

All Faculty Publications

The changing nature of armed conflict has had a dramatic impact on the security risks facing humanitarian personnel. Historically, the safety of humanitarian aid delivery was secured through the consent of the relevant Parties to the conflict. However, non-international ethnically-motivated armed conflicts, failed and failing states, and insurgency-based warfare have fundamentally challenged the viability of this traditional security paradigm. In confronting today's complex security climate, humanitarian organizations are faced with a diverse menu of alternatives to enhance their security. The debate over armed protection that has sharply divided the humanitarian community is explored in this paper, including a critique of …

Catalytic Wet Air Oxidation Of Mono Azo Dye Orange Ii: Catalyst Selection, Reaction Kinetics, And Modeling, Pinar Ozdural

Civil & Environmental Engineering Theses & Dissertations

Wastewaters generated as byproducts of dyeing processes are not treatable with conventional methods. It has been estimated that among the 900,000 tons of different dyes produced annually in the world, approximately 10–15% are lost in wastewater streams during manufacturing and processing operations. Once in rivers and streams, dyes cause major problems, such as reducing light penetration, or displaying toxic effects on aquatic life. Therefore, it is essential that dyes are removed from wastewaters before being discharged into the environment.

This study focuses on the catalytic wet air oxidation (CWAO) of Orange II, a mono azo dye used in large amounts …

The Boundaries Of The Criminal Law: The Criminalization Of The Non-Disclosure Of Hiv, Isabel Grant

All Faculty Publications

In this paper, the author examines the trend toward the increased criminalization and punishment of persons with HIV who fail to inform their sexual partners of their HIV-positive status. Since the Supreme Court of Canada's decision in R. v. Cuerrier, such behaviour may constitute aggravated assault or aggravated sexual assault, the latter offence carrying a maximum sentence of life imprisonment. The paper surveys the Canadian case law and highlights the trend towards the imposition of increasingly harsh sentences. After reviewing public-health and criminal law options for dealing with non-disclosure of one's HIV status, the author concludes that criminal law should …

The Effects Of Religious Contextual Norms, Structural Constraints, And Personal Religiosity For Abortion Decisions, Amy Adamczyk

Publications and Research

Researchers have established that individual religiosity influences abortion attitudes, and that abortion attitudes, in turn, shape abortion restrictions and access. Less clear is whether religion and abortion structural constraints influence abortion decisions. This study examines the several individual, contextual, and structural factors that could shape the abortion decisions of women who conceive before marriage. Special attention is given to the importance of academic aspirations and structural constraints, in contrast to religious beliefs and county religious context, for making an abortion decision. Hierarchical modeling techniques and two waves of data from the National Longitudinal Study of Adolescent Health (Add Health) are …

Corporate Boards Of Directors: Advisors Or Supervisors, Tamar Frankel

Faculty Scholarship

What makes for a well-functioning corporate board? In this Article I argue that one important condition is that board members must understand and agree upon the group's objectives and its roles. If a corporate board of directors (Board) does not agree on what it is supposed to do; or, worse still, if Board members disagree about the Board's mission and its implementation, then the Board is likely to become dysfunctional-inefficient and ineffective. The Board's missions, however, may be mixed and their forms of implementation may conflict. In this case, the balance between the two missions must be established, and it …

Market-Based Licensing For Hpv Vaccines In Developing Countries, Kevin Outterson, Aaron S. Kesselheim

Faculty Scholarship

Human papillomavirus (HPV) vaccines hold great promise for preventing cervical cancer, but 93 percent of mortality worldwide occurs in low- and middle-income countries, where high vaccine costs can restrict dissemination. Current models for promoting international access to health care innovations include differential pricing, advance market commitments, and voluntary and compulsory licensing. Some of these mechanisms have been effective, but much room for improvement remains. We discuss the usefulness of a new type of license that uses market forces to lower prices through generic competition in low- and middle-income countries while ensuring that pharmaceutical companies are appropriately reimbursed for their research …

Multi-Algorithmic Cryptography Using Deterministic Chaos With Applications To Mobile Communications, Jonathan Blackledge

Articles

In this extended paper, we present an overview of the principal issues associated with cryptography, providing historically significant examples for illustrative purposes as part of a short tutorial for readers that are not familiar with the subject matter. This is used to introduce the role that nonlinear dynamics and chaos play in the design of encryption engines which utilize different types of Iteration Function Systems (IFS). The design of such encryption engines requires that they conform to the principles associated with diffusion and confusion for generating ciphers that are of a maximum entropy type. For this reason, the role of …

Audio Data Verification And Authentication Using Frequency Modulation Based Watermarking, Jonathan Blackledge, Omar Farooq

Articles

An approach to watermarking digital signals using frequency modulation - ‘Chirp Coding’ - is considered. The principles underlying this approach are based on the use of a matched filter to reconstruct a ‘chirp stream’ code that is uniquely robust. The method is generic in the sense that it can, in principle, be used for a variety of different signal (the authentication of speech and biomedical signals, for example). Further, by generating a bit stream that is signal dependent, chirp coding provides a method of self-authentication, which has a wide range of applications including copyright protection and digital rights management. However, …

Proposal For Using A Studio Format To Enhance Institutional Advancement, Shannon Chance

Articles

Universities today need to become quicker on their toes. They must continually scan the environment and seize emerging opportunities – and institutional advancement must lead this effort. An unfortunate number of institutional advancement operations are ill equipped for the task at hand. Many suffer from high staff turnover and overly hierarchical systems that refl ect excessive fragmentation and compartmentalization. They inadvertently perpetuate stifl ing and unnecessary bureaucracy. Organizing advancement efforts around the metaphor of the design studio or creative workshop promises to (a) pool talent, (b) cultivate collaboration, and (c) align diverse but related interests in order to promote fruitful …

From Obsession To Confession: A False Confession Paradigm In The Murder Of Jon Benet Ramsey, Morgan Moffa, Judith Platania

Arts & Sciences Faculty Publications

In this study, we used a fact pattern similar to the John Mark Karr scenario to examine perceptions of DNA and confession evidence. Specifically, we hypothesized that DNA evidence, confessor level of psychopathology, and presence or absence of Miranda protections would affect participants’ perceptions of guilt and attitudes towards the interrogation process. One hundred nine undergraduates read a two-page summary based on John Mark Karr’s confession. Summaries varied based on psychopathology of confessor, the presence or absence of DNA evidence, and the provision of Miranda warnings prior to confession. The DNA manipulation explained participants’ attitudes towards specific aspects of the …

The Impact Of The Blackberry On Couple Relationships, Jurgen Dieter Czechowsky

Theses and Dissertations (Comprehensive)

This research focused on the BlackBerry developed by Research In Motion and its impact on couple relationships. The areas examined were couple communication, time spent together, and martial satisfaction using grounded theory, a demographic survey, the ENRICH Marital Satisfaction Scale and interviews. Ten couples participated and reported that the BlackBerry offered many practical applications for their relationship. The research showed that communication via the BlackBerry resulted in fewer face-to-face interactions. There was no increase in time together and for some time decreased. Martial satisfaction had increased for two couples, decreased for two couples with no influence for the rest of …
