Validation Of The Suicide Resilience Inventory-25 (Sri-25) With African American High School Students, Stephanie Elizabeth Gantt

Dissertations and Theses @ UNI

Suicide is the cause of death for nearly 30,000 deaths per year in the United States (Henkel, 2005). Studies show that rates of suicide have increased dramatically among African Americans ages 10-19 years, yet the overall suicide rate of African American adolescents is still lower than that of their Caucasian counterparts (Gould & Kramer, 2001 ; Greening & Stoppelbein, 2002). Some researchers have begun to study protective factors, particularly resilience, as one of the factors that should be maximized to reduce the rate of adolescent suicidal thoughts and behaviors. In particular, resiliency is an adaptive, stress-resistant personal quality that allows …

Assessment Of The Source And Transformation Of Nitrate In The Cedar River Watershed By Using Stable Isotopes Of Nitrogen, Sushil Gautam

Dissertations and Theses @ UNI

Stable isotopes of nitrogen were used to assess the source and fate of nitrate in the Cedar River Watershed, Iowa. Ground water samples from 20 private wells and surface water samples from 10 sites in the Cedar River and its tributaries were collected. A total of 90 samples were collected during the growing season from May through September 2006. In 35% of the wells, nitrate concentration exceeded the U.S. Environmental Protection Agency's recommended maximum contaminant level (MCL) of 45 mg/1 (as NO3-) for drinking purposes. Eight (8) out of 10 samples exceeded MCL for nitrate in the first set of …

They're Making All The Wrong Decisions - Unintended Consequences Of Empowerment Resulting From Individual Situated Cognition, Jonathan Coleman

Student Scholarship

This paper describes how organizational culture affects individual level decision­ making processes in large organizations. This is particularly notable in the effect on the relative communication of qualitative versus quantitative information. Different levels of success in communicating these two kinds of information affect the development of the situated cognition prior to making a particular decision. We present the findings of a qualitative research study of thirteen executive level decision makers representing four Fortune 100 companies from four diverse industries. These executives were involved in strategic decisions in the normal course of business and also had particular experience in decisions involving …

Organizational Trauma: A Phenomenological Study Of Leaders In Traumatized Organizations, Shana D. Lynn Hormann

Antioch University Dissertations & Theses

While some organizations die when trauma erupts, others do not succumb. They live and even thrive. The purpose of this study was two-fold: 1. To learn from leaders their perspectives about key conditions that allow organizations to withstand and heal from organizational trauma; and, 2. To inform practice about building and strengthening these conditions in organizations. Participants were leaders who led their organizations during an organizational trauma or who came into programs after the trauma occurred to facilitate recovery. Nine executive directors for sexual assault programs participated in this hermeneutic phenomenological study, sharing their experiences and reflections. Two composite depictions …

A Community-Based Social Marketing Campaign To Green The Offices At Pacific University: Recycling, Paper Reduction, And Environmentally Preferable Purchasing, Elaine Janet Cole

Extending And Measuring The Quality Of Fresh-Cut Fruit And Vegetables: A Review, Ana Belen Martin-Diana, Daniel Rico, Gary Henehan, Jesus Maria Frias, J. Barat

Articles

The market sales of ready - to - use vegetables have grown rapidly in recent decades as a result of changes in consumer attitudes especially consumption of fresh-cut lettuce and carrot due to their use in prepared salads. Chlorine solutions have been widely used to sanitise fruit and vegetables in the fresh-cut industry. However, the association of chlorine with the possible formation of carcinogenic chlorinated compounds in water has called into question the use of chlorine in food processing. There is a real need to find alternatives for preservation of fresh-cut fruit and vegetables in order to improve the efficacy …

Enterobacter Sakazakii: An Emerging Microbe With Implications For Infant Health, N. R. Mullane, B. Healy, Ciara Walsh, C. Iversen, P. Whyte, P. G. Wall, T. Quinn, Seamus Fanning

Articles

Enterobacter sakazakii (E. sakazakii) is an opportunistic pathogen and the aetiological agent in rare but life-threatening cases of meningitis, necrotizing enterocolitis, and sepsis in infants. Among infants, those at greatest risk are neonates (<28 >days), particularly those born prematurely or of low birth weight (g). Consumption of contaminated powdered infant formula (PIF) has been epidemiologically linked with cases of infection. Contamination can occur during the manufacturing process or during postmanufacture reconstitution of formula. Development of rapid, sensitive and specific detection methods will facilitate manufacturers efforts to reduce the occurrence of E. sakazakii in the final powdered product. Furthermore, since PIF …

Development And Assessment Of A Rapid Method To Detect Escherichia Coli O26, O111 And O157 In Retail Minced Beef., Mary Murphy, Anne Carroll, Paul Whyte, Micheál O'Mahoney, Wayne Anderson, Eleanor Mcnamara, Seamus Fanning, Ciara Walsh

Articles

A molecular-based detection method was developed to detect Escherichia coli O26, O111 and O157 in minced (ground) beef samples. This method consists of an initial overnight enrichment in modified tryptone soya broth (mTSB) and novobiocin prior to DNA extraction and subsequent serogrouping using a triplex PCR. This method has a low limit of detection and results are available within 24 hours of receipt of samples. Once optimized, this rapid method was utilized to determine the prevalence of these E. coli serogroups in six hundred minced beef samples all of which were previously examined by immunomagnetic separation (IMS) and selective plating …

Simultaneous Modelling Of The Thermal Degradationa Kinetics Of Pectin, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Gary Henehan, Jesus Maria Frias

Articles

The thermal degradation kinetics of pectin methylesterase (PME) from carrot and lettuce were studied. Fresh extracts were exposed to temperatures from 55 to 70 °C until the enzyme was inactivated. A model based on the presence of two forms of the enzyme, one active and one non-active, is proposed. The natural variability of the PME activity was taken into the model in the form of normally distributed random effects. The common model parameters obtained (cleavage constant (0.0395±0.0062 s⁻¹), degradation constant (0.556±0.112 s⁻¹), cleavage energy of activation (469±23 kJ mol⁻¹) and degradation energy of activation …

Ef Fi Cacy Of Steamer Jet-Injection As Alternative To Chlorine In Fresh-Cut Lettuce, Daniel Rico, Ana Belen Martin-Diana, Jesus Maria Frias, J. Barat, Gary Henehan, Catherine Barry-Ryan

Articles

The use of calcium lactate solutions has been shown to be a healthy alternative to chlorine washing in order to maintain the shelf-life of fresh-cut products. The aim of this research was to analyse the effects of calcium lactate (15 g L⁻¹) treatment at 25 °C and 50 °C (heat-shock) on the textural properties of sliced carrots and to compare those with the chlorine treatment (120 mg L⁻¹) widely used in industry. Several direct and indirect markers of textural changes in carrots during storage were used: Instron textural analysis, Cryo-SEM and optical microscopic, sensory analysis, pectin …

Efficacy Of Steamer Jet-Injection As Alternative To Chlorine In Fresh-Cut Lettuce, Ana Belen Martin-Diana, Daniel Rico, Catherine Barry-Ryan, Jesus Maria Frias, Gary Henehan, J. Barat

Articles

Short-time steam processing was used as an alternative to chlorine (100 mg L⁻¹) in sanitising fresh-cut lettuce. Quality (pH, water content, colour, potential browning, browning-related enzymes and texture), safety (mesophilic counts) and antioxidant markers (ascorbic and carotenoids) were monitored in lettuce stored for 10 days at 4 °C. The steam treatment produced a shocking effect on lettuce metabolism, showing a significant (p < 0.05) reduction in respiration (from day 3 to 7) and a partial inactivation of browning-related enzymes. Both effects were reflected in a significant reduction of browning. From a safety point of view, steam treatment kept the mesophilic load as low as chlorine treatment, and significantly lowers than the water control. However, antioxidant content, especially ascorbic acid but also carotenoids in a lower degree, showed a reduction compared with chlorine-treated samples. Despite the lower visual browning in steam-treated samples, the sensory panel scored similar values of acceptability and fresh appearance for both samples similarity.

Reservoirs Of Danger: The Evolution Of Public And Private Law At The Dawn Of The Information Age, Danielle K. Citron

Faculty Scholarship

A defining problem at the dawn of the Information Age will be securing computer databases of ultra-sensitive personal information. These reservoirs of data fuel our Internet economy but endanger individuals when their information escapes into the hands of cyber-criminals. This juxtaposition of opportunities for rapid economic growth and novel dangers recalls similar challenges society and law faced at the outset of the Industrial Age. Then, reservoirs collected water to power textile mills: the water was harmless in repose but wrought havoc when it escaped. After initially resisting Rylands v. Fletcher's strict liability standard as undermining economic development, American courts and …

A Search-Costs Theory Of Limiting Doctrines In Trademark Law, Stacey Dogan, Mark A. Lemley

Faculty Scholarship

Trademarks have value because they reduce consumer search costs and thus promote overall efficiency in the economy.

While the search costs theory provides a compelling argument for trademark rights, it also compels an equally important - but often overlooked - set of principles for defining and limiting those rights. Certainly, trademark laws can make it easier and cheaper for consumers to locate products with desired qualities, thus making markets more competitive. Yet if carried too far, trademark law can do the opposite: it can entrench market dominance by leading firms and make it harder for competitors to crack new markets. …

Tort Negligence, Cost-Benefit Analysis, And Tradeoffs: A Closer Look At The Controversy, Kenneth Simons

Faculty Scholarship

What is the proper role of cost-benefit analysis in understanding the tort concept of negligence or reasonable care? A straightforward question, you might think. But it is a question that manages to elicit groans of exasperation from those on both sides of the controversy.

For most utilitarians and adherents to law and economics, the answer is obvious: to say that people should not be negligent is to say that they should minimize the sum of the costs of accidents and the costs of preventing accidents. Under the economic formulation of the famous Learned Hand test, they should take a precaution …

Biomedical Ethics And The Law: A Critical Perspective, Keith N. Hylton

Faculty Scholarship

Health law, a fast growing field of scholarship, appears to consist largely of two schools. One focuses on health care antitrust, taking as its fundamental premise the notion that health care markets should be distinguished from and treated differently than other markets. This premise underlying health care antitrust is based on a few recurring features of health care markets, such as informational asymmetry, that are taken as sufficient bases for treating them differently.¹ The other school of health law is biomedical ethics, which has taken on increasing importance in view of the many tradeoffs that arise when health care …

Tackling The "Evils" Of Interlocking Directorates In Healthcare Nonprofits, Nicole Huberfeld

Faculty Scholarship

Though they are sometimes regarded as corrupt, the complete cessation of existing interlocking boards in healthcare nonprofits is not immediately attainable and arguably not always desirable. This article comments that the doctrine of fiduciary duties should be modified to encompass the reality of overlapping boards; to recognize the trend toward more global, comprehensive, and proactive governance in the healthcare sector; and to enable directors to decipher, document, and resolve conflicts at a more meaningful point in their decision-making processes by expanding the doctrine of the duty of obedience.

To facilitate the discussion, the article draws on three examples of overlap …

The Emotional Intelligence Of Chief Development Officers In Public Higher Education Institutions Of The Mid Atlantic Region And Organizational Climate Perceptions Of Their Development Teams., Rosemary M. Thomas

Additionally, demographic data was collected and tested as well to determine if such factors as: gender, age, years of experience, and length of tenure were significantly related to the organizational climate scores. Chief development officers (CDOs) from AASCU member comprehensive public colleges and universities in the Mid-Atlantic region were invited to participate and their development staff members were included by virtue of the CDO responding. The Bar-On Emotional Quotient …

Cancer And The Constitution: Choice At Life's End, George J. Annas

Faculty Scholarship

J. M. Coetzee's violent, anti-apartheid Age of Iron, a novel the Wall Street Journal termed “a fierce pageant of modern South Africa,” is written as a letter by a retired classics professor, Mrs. Curren, to her daughter, who lives in the United States. Mrs. Curren is dying of cancer, and her daughter advises her to come to the United States for treatment. She replies, “I can't afford to die in America. . . . No one can, except Americans.” Dying of cancer has been considered a “hard death” for at least a century, unproven and even quack remedies have been …

Physicians And Torture: Lessons From The Nazi Doctors, Michael Grodin, George J. Annas

Faculty Scholarship

How is it possible? What are the personal, professional and political contexts that allow physicians to use their skills to torture and kill rather than heal? What are the psychological characteristics and the social, cultural and political factors that predispose physicians to participate in human rights abuses? What can be done to recognize at-risk situations and attempt to provide corrective or preventive strategies? This article examines case studies from Nazi Germany in an attempt to answer these questions. Subjects discussed include the psychology of the individual perpetrator, dehumanization, numbing, splitting, omnipotence, medicalization, group dynamics, obedience to authority, diffusion of responsibility, …

The Politics Of Health Promotion: Analyzing Healthy Public Policy's Impact On Tobacco Control In United States And South Africa., Frederick Appah

Graduate Theses, Dissertations, and Problem Reports (ETD)

This public health policy, international organization and comparative public policy and politics research looks at the impact of health promotion on tobacco control in the United States and South Africa from the Canadian Lalonde report of 1974 to 2004. The healthy public policy concept is used as a tool to analyze the possible policy changes and outcomes that the health promotion perspective has brought to the national tobacco control policies, programs and strategies of the two developmentally and structurally different but strategically and institutionally similar countries. The study uses a combination of documentary and elite interview analysis. The research finds …

Deliberating Groups Versus Prediction Markets (Or Hayek's Challenge To Habermas), Cass R. Sunstein

Coase-Sandor Institute for Law & Economics Research Paper Series

For multiple reasons, deliberating groups often converge on falsehood rather than truth. Individual errors may be amplified rather than cured. Group members may fall victim to a bad cascade, either informational or reputational. Deliberators may emphasize shared information at the expense of uniquely held information. Finally, group polarization may lead even rational people to unjustified extremism. By contrast, prediction markets often produce accurate results, because they create strong incentives for revelation of privately held knowledge and succeed in aggregating widely dispersed information. The success of prediction markets offers a set of lessons for increasing the likelihood that groups can obtain …

Participatory Gis Approaches To Environmental Impact Assessment: A Case Study Of The Appalachian Corridor H Transportation Project., Ram Alagan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation explores the strengths and weaknesses of Participatory Geographic Information System (PGIS) approaches to Environmental Impact Assessment (EIA) with a specific focus on the potential contribution of Geo-visualization (GVIS) in this process. The approach draws heavily on concepts developed under the broad umbrella of GIS and Society and Critical GIS. PGIS recognizes the political economy of GIS in terms of data access, data representation, structural knowledge distortion, and community empowerment as being legitimate and significant issues in the application of GIS in community projects. EIA has been adopted as one of several important environmental practices that seek to engage …

A Public Choice Theory Of Criminal Procedure, Keith N. Hylton, Vikramaditya Khanna

Faculty Scholarship

We provide an additional justification for the pro-defendant bias in Anglo-American criminal procedure that supplements the most commonly forwarded justifications to date. The most commonly forwarded rationale for the prodefendant bias is that the costs of false convictions-specifically, the sanctioning and deterrence costs associated with the erroneous imposition of criminal sanctions-are greater than the costs of false acquittals. We argue that this rationale provides at best a partial justification for the extent of prodefendant procedural rules. Under our justification, prodefendant protections serve primarily as constraints on the costs associated with rent seeking in the law enforcement process. The theory developed …

Contract Law And Distribution In The Age Of Welfare Reform, Daniela Caruso

Faculty Scholarship

This Article tracks the ongoing adaptation of U.S. contract law to the 1990s’ contraction of the welfare state. Some courts strive to compensate for the shortage of welfare services and to pursue redistributive goals. This Article provides examples of this trend and then analyzes the non-linear relation between doctrines, judicial redistribution, and welfare politics in both case law and scholarship. Finally, this Article discusses the role of socially sensitive judicial discourse in light of contemporary welfare politics and explains its continuing importance.
