Guideline Institutionalization: The Role Of Merger Guidelines In Antitrust Discourse, Hillary Greene
Guideline Institutionalization: The Role Of Merger Guidelines In Antitrust Discourse, Hillary Greene
William & Mary Law Review
With the growth of the administrative state, agency-promulgated enforcement policy statements, typically referred to as guidelines, have become ubiquitous in the U.S. federal system. Yet, the actual usage and impact of such guidelines is poorly understood. Often the issuing agencies declare the guidelines to be nonbinding, even for themselves. Notwithstanding this disclaimer, the government, private parties, and even the courts frequently rely on the guidelines in a precedent-like manner. In this Article, Professor Greene examines the evolution of one system of enforcement policy guidelines-the U.S. federal antitrust merger guidelines--and finds that these guidelines have acted as a stealth force on …
Putting The Ninth Ward On The Map: Race, Place, And Transformation In Desire, New Orleans, Rachel Breunlin
Putting The Ninth Ward On The Map: Race, Place, And Transformation In Desire, New Orleans, Rachel Breunlin
Anthropology Faculty Publications
In this article, we consider how long-term patterns of resistance to structural violence inform citizens’ responses to displacement before and after Katrina. Drawing on Abdou Maliq Simone’s (2004) conceptualization of people as infrastructure, we recenter the discussion about the rebuilding of New Orleans around displaced residents, taking the place-making practices of members of a social club as a lens through which to examine the predicament of the city as a whole. Members have been generating alternative ways of thinking about and dwelling together in a restructuring city. Their perspectives are articulated through in-depth interviews, focus groups, and the embodied practices …

Mindfulness As A Moderator Of Coping Response And The Abstinence Violation Effect : A Test Of The Role Of Mindfulness In The Relapse Prevention Model For Exercise., Christi S. Ulmer 1964-
Electronic Theses and Dissertations
The importance of physical activity in preventing disease and promoting health is increasingly evident in health outcomes research. Although most adults in the U.S. have initiated exercise programs at some point in their lives, research suggests that they have difficulty maintaining beneficial levels of physical activity and exercise. With escalating rates of obesity and physical inactivity, the importance of understanding processes by which individuals engage in and maintain physical activity cannot be understated. The Relapse Prevention Model (RPM), developed for use with addiction, has been successfully used to explore factors associated with exercise drop-out, or "exercise relapse". In the current …
Anti-Haitianism, Historical Memory, And The Potential For Genocidal Violence In The Dominican Republic, Edward Paulino
Anti-Haitianism, Historical Memory, And The Potential For Genocidal Violence In The Dominican Republic, Edward Paulino
Genocide Studies and Prevention: An International Journal
Following the 2005 murder of a Dominican woman near the border between the Dominican Republic and Haiti, Haitian communities were deported en masse and their homes violently ransacked by Dominican civilians seeking revenge. These violent expulsions were not only human-rights violations but part of a historic pattern of anti-Haitianism in the Dominican Republic that originated in the nineteenth century. This article calls attention to the possibility of genocidal violence in the Dominican Republic by examining the violent 2005 attacks on the Haitian community there. It suggests that an anti-Haitian legacy that includes the 1937 Haitian Massacre and the contemporary and …
The Restless World Of Leonardo Alishan (March 1951–January 2005): A Burnt Offering On The Altar Of The Armenian Genocide, Rubina Peroomian
The Restless World Of Leonardo Alishan (March 1951–January 2005): A Burnt Offering On The Altar Of The Armenian Genocide, Rubina Peroomian
Genocide Studies and Prevention: An International Journal
In his short career as a writer, poet, and literary critic, Leonardo Alishan left a rich literary legacy, a legacy that is not widely known. This article attempts to shed light on an important segment of his literary output: his creations in the genre of genocide literature. Alishan was a third-generation survivor of the Armenian Genocide, the inheritor of his grandmother’s devastating memories, living in the grip of the nightmare of the Catastrophe, never able to transcend it. The everpresent pain that dragged his grandmother from one mental hospital to another reverberated in his literary work, painting a microcosm of …

Depression, Anxiety, Hazardous Drinking, Subjective Burden, And Rewards In Family Caregivers Of Patients With Chronic Liver Disease, Lois Vennesta Bolden
Theses and Dissertations (ETD)
This descriptive correlation study had three purposes. The study first described depressive and anxiety symptom levels, prevalence of hazardous drinking, rewards, and subjective burden reported by family caregivers of patients with chronic liver disease (CLD). Second, the investigator compared depressive and anxiety symptom levels, prevalence of hazardous drinking, rewards, and subjective burden reported by African Americans family caregivers with those reported by Caucasian family caregivers of patients with CLD. The third purpose was to determine the predictors of subjective burden and mental health status of family caregivers of persons with CLD.

Challenging Transformation's Clichés, Antulio J. Echevarria Dr.
Challenging Transformation's Clichés, Antulio J. Echevarria Dr.
Books, Monographs & Collaborative Studies
Critical thinkers analyze and refine ideas underpinning the foundation of American defense policy and military strategy today so the defense community can apply them in strategy and force development. This is an ongoing process: new ideas emerge, are tested, and adopted, revised, or discarded. The author challenges some of the accepted notions that have become foundational to contemporary theories of military transformation. In his view, any endeavor as resource-intensive as military transformation is too important to rest on uncontested truths.

Iraq, Women's Empowerment And Public Policy, Sherifa D. Zuhur Dr.
Books, Monographs & Collaborative Studies
The role and experience of women is not always considered in wartime or during stabilization and reconstruction operations. In Iraq, it is essential to consider women’s needs and the obstacles they now face. The author examines some of the difficulties that attend policy formulation on Iraqi women, who have identified the security situation and basic services as their top priorities. Issues and contours of family law are explained, as the future of family law in emerging Iraq is as yet undetermined. Along with an increased political presence, legal reforms, together with educational and employment opportunities, have been the planks of …
Does Seed-Caching Experience Affect Spatial Memory Performance By Pinyon Jays?, B. Lucas Stafford, Russell P. Balda, Alan Kamil
Does Seed-Caching Experience Affect Spatial Memory Performance By Pinyon Jays?, B. Lucas Stafford, Russell P. Balda, Alan Kamil
Papers in Behavior in Biological Sciences
Food-storing birds use spatial memory to find previously cached food items. Throughout winter, pinyon jays (Gymnorhinus cyanocephalus) rely heavily on cached pinyon pine (Pinus edulis) seeds. Because of a recent severe drought, pinyon pine trees had not produced a significant seed crop for several years. Therefore, 1- and 2-year-old birds never had the opportunity to cache and recover seeds and birds 4 or more years of age had not recovered seeds in 3 years. This study examined whether natural but extreme variability in experience might result in differences in abstract spatial memory ability during a non-cache …

Torshizi, Kamran Ghafarzadegan
Saudi Medical Journal
OBJECTIVE: The human epidermal growth factor receptor-2 (HER-2)/neu is a proto-oncogene that is amplified in 10-30% of breast cancers. It is known to be associated with a poor overall survival. We studied the relationship between its amplification and different histological gradings of breast cancer. METHODS: We studied 196 patients diagnosed with breast cancer in 2005 at the Omid and Ghaem Training Hospital, Mashhad Medical University, Iran. The HER-2/neu oncoprotein was measured by immunohistochemistry and the histological gradings were carried out according to the Bloom-Richardson Grading system. RESULTS: Sixty-seven (34.2%) cases were HER-2/neu positive and 129 (65.8%) cases were HER-2/neu negative. …

The purpose of this study was to examine behaviors related to nutrition and physical activity of inner-city minority adolescents, and their perception of normal weight and overweight. The research study used a descriptive, non-experimental design which had a convenience sample of thirty-seven 8th grade minority adolescents who attended a chartered urban K-8 grade school in Northern California. There were no statistically significant differences in the results, however, over 50% of the students reported not eating the recommended daily servings of fruits and vegetables. Another 68% reported participating more than 30 minutes in exercising or playing sports during physical education class. …
Stress Reduction: A Neighborhood Introduction, Barbara D. Johnson
Stress Reduction: A Neighborhood Introduction, Barbara D. Johnson
Master's Projects
Responding to reported health concerns a stress reduction program was developed for residents of an urban Latino neighborhood struggling with poverty, crime, and limited access to healthcare. The revised Health Promotion Model (HPM) was used as a framework (Pender, 1996). A qualitative study testing a 5-week Mindfulness-based Stress Reduction (MBSR) intervention was imbedded into the program 18 months after its implementation. Utilizing a pre/post test design participants were predicted to demonstrate significant reductions in post-intervention mean scores for 3 self-report measures, the Cohen Perceived Stress Scale, General Sleep Disturbance Scale, and a modified Memorial Symptom Assessment Scale. A 91% drop …
The Cost Of Negative Perceptions Of The Work Environment Among Intermediate Intensive Care Unit Nurses, Joselyn Peralta
The Cost Of Negative Perceptions Of The Work Environment Among Intermediate Intensive Care Unit Nurses, Joselyn Peralta
Master's Projects
This descriptive study assessed the perceptions of the work environment and the retention plans among registered nurses (RNs) who worked in the Intermediate Intensive Care Unit at a tertiary university hospital. Results from the Moos Work Environment Scale found that nurses perceived high levels of work pressure and low levels of clarity, coworker cohesion, and supervisor support. Results indicated that the intent to leave the unit was dependent on the nurses having other options in nursing, desiring further education, an undesirable scheduling process and unsafe patient care. The direct and indirect costs to hospitals could be offset by developing strategies …
Training Parents To Treat Noncompliance In Children With Developmental Disabilities Using Guided Compliance, Christine Bennett
Training Parents To Treat Noncompliance In Children With Developmental Disabilities Using Guided Compliance, Christine Bennett
Masters Theses
Noncompliance with parental directions is a critical target for children with developmental disabilities for several reasons, including the frequency of the problem and its impact on caregivers. Three decades of research have shown the effectiveness of guided compliance with children with developmental disabilities; however, only a few studies have examined the effects of parent-implemented guided compliance with this population (Handen, Parrish, McClung, Kerwin, & Evans, 1992; Smith & Lerman, 1999; Tarbox, Wallace, & Penrod, 2003). Three children with developmental disabilities and one primary caregiver for each participated in the present study. Parents were trained in three-step guided compliance (i.e., command, …

Art, The Social Enzyme: The Emergence Of An Art Community In The Rio Grande Valley, Heaven Lashley
Theses and Dissertations - UTB/UTPA
This study explores the emergence of an art community in the Rio Grande Valley (RGV) region of South Texas. In researching this objective, I relied on observations at many gallery public functions where I had the opportunity to observe the interactions between prospective buyers, gallery owners and artists. I also visited with gallery owners and artists many times in small group settings where I raised open ended questions about the region's artists and other historical developments that would allow me to put together a cohesive story about the emergence of the art community
This study began as an unstructured exploration …

Maintaining An Immigrant Heritage Language Other Than Spanish Or English In The Bilingual Culture Of The Rio Grande Valley Of South Texas, Sonia A. Shepherd
Theses and Dissertations - UTB/UTPA
A 2005 study in the bilingual Spanish/English Rio Grande Valley of South Texas investigates the language strategies used by immigrant families from China, Greece, Hungary, Japan, the Philippines, Russia, Taiwan, and the Ukraine to preserve their heritage languages and pass them on to their children. Personal interviews determine that all the parents are well-educated and from an above average socio-economic level. This investigation categorizes the various strategies used by the parents. All the immigrant parents emphasize that the main reason they want to preserve the heritage language with their children is to insure that the children can continue to communicate …

Marketing
In this era of increased global cooperation, a growing number of negotiators conduct business in multiple countries and, therefore, need access to a systematic comparison of negotiating tendencies across a wide range of countries. Empirical work systematically comparing variations across a range of cultures is scarce. A comparative analysis of negotiating tendencies in five countries is presented. This study establishes the utility of the [Salacuse, J. (1998) Ten ways that culture affects negotiating style: Some survey results. Negotiation Journal, 14(3): 221–235] framework in identifying country differences across five countries, representing five cultural clusters. Significant differences in negotiation orientations both …

Vanderbilt Law School Faculty Publications
Specialization is common in medicine. Doctors become oncologists, radiologists, urologists, or even hernia repair specialists. Specialization is also common among practicing lawyers, who become estate planners or products liability lawyers or securities litigators. Judges, however, have historically been generalists who preside over any and all cases. This requires that judges become acquainted with the rules of civil procedure, the rules of criminal procedure, the evidentiary rules applicable to both civil and criminal cases, and the substantive law in almost every area. From the simplest slip-and-fall to the most complicated antitrust case, and nearly every civil and criminal action in between, …
Following In Their Footsteps: The Risks Of The Intergenerational Cycle Of Incarceration Among Inmates And Their Children, Megan Elizabeth Harris
Following In Their Footsteps: The Risks Of The Intergenerational Cycle Of Incarceration Among Inmates And Their Children, Megan Elizabeth Harris
All Theses
The purpose of this thesis was to test the proposition that parents who are currently incarcerated are at high risk for having children who are also incarcerated. Furthermore, several risk factors, commonly found in homes with previously or currently incarcerated members, were identified and analyzed to predict the odds of an incarcerated parent also having an incarcerated child.
The current study found that the majority of the demographic variables (gender, race, and marital status) were significant predictors of child incarceration. Furthermore, only a few risk factors were found to be significant predictors of an inmate’s child being incarcerated: an inmate …

After-Schools Programs And Their Influence On Parent Involvement With Children At Home, Marci Malone
Undergraduate Honors Capstone Projects
Eight-year-old Victoria, with hands on hips and chin stuck up, defiantly said, "No mom, I want to stay for After-School Club. I don't care about the dentist." Her mother patiently responded by telling Victoria, "I know you want to stay but we have to leave now or we will be late for our appointment." The little girl, seeming to know from experience that her mother would not budge, stomped her foot as she began leaving the school saying, "I hate when I have to miss After-School Club!"
