A Study of the Intent to Fully Utilize Electronic Personal Health Records in the Context of Privacy and Trust (open access)

A Study of the Intent to Fully Utilize Electronic Personal Health Records in the Context of Privacy and Trust

Government initiatives called for electronic health records for each individual healthcare consumer by 2014. the purpose of the initiatives is to provide for the common exchange of clinical information between healthcare consumers, healthcare providers, third-party payers and public healthcare officials.This exchange of healthcare information will impact the healthcare industry and enable more effective and efficient application of healthcare so that there may be a decrease in medical errors, increase in access to quality of care tools, and enhancement of decision making abilities by healthcare consumers, healthcare providers and government health agencies. an electronic personal health record (ePHR) created, managed and accessed by healthcare consumers may be the answer to fulfilling the national initiative. However, since healthcare consumers potentially are in control of their own ePHR, the healthcare consumer’s concern for privacy may be a barrier for the effective implementation of a nationwide network of ePHR. a technology acceptance model, an information boundary theory model and a trust model were integrated to analyze usage intentions of healthcare consumers of ePHR. Results indicate that healthcare consumers feel there is a perceived usefulness of ePHR; however they may not see ePHR as easy to use. Results also indicate that the perceived usefulness of …

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress (open access)

9-Lipoxygenase Oxylipin Pathway in Plant Response to Biotic Stress

The activity of plant 9-lipoxygenases (LOXs) influences the outcome of Arabidopsis thaliana interaction with pathogen and insects. Evidence provided here indicates that in Arabidopsis, 9-LOXs facilitate infestation by Myzus persicae, commonly known as the green peach aphid (GPA), a sap-sucking insect, and infection by the fungal pathogen Fusarium graminearum. in comparison to the wild-type plant, lox5 mutants, which are deficient in a 9-lipoxygenase, GPA population was smaller and the insect spent less time feeding from sieve elements and xylem, thus resulting in reduced water content and fecundity of GPA. LOX5 expression is induced rapidly in roots of GPA-infested plants. This increase in LOX5 expression is paralleled by an increase in LOX5-synthesized oxylipins in the root and petiole exudates of GPA-infested plants. Micrografting experiments demonstrated that GPA population size was smaller on plants in which the roots were of the lox5 mutant genotype. Exogenous treatment of lox5 mutant roots with 9-hydroxyoctadecanoic acid restored water content and population size of GPA on lox5 mutants. Together, these results suggest that LOX5 genotype in roots is critical for facilitating insect infestation of Arabidopsis. in Arabidopsis, 9-LOX function is also required for facilitating infection by F. graminearum, which is a leading cause of Fusarium head …

Bridging the Gap Between Access and Success: a Study of the Impact of an Access and Success Program on Academic Outcomes of Low-income College Freshmen (open access)

Bridging the Gap Between Access and Success: a Study of the Impact of an Access and Success Program on Academic Outcomes of Low-income College Freshmen

In response to the increasing cost of college, colleges and universities are leveraging financial aid and academic support services to implement access and success programs intended to help financially disadvantaged students afford and persist through a baccalaureate degree program. This research is a study of the efficacy of one such program at a large research university in the southwestern region of the United States. The study sample included low-income program participants in four cohorts of freshmen enrolling for the first time in college from fall 2007 (Cohort 1) to fall 2010 (Cohort 4) and a comparison group of almost 400 low-income freshmen who enrolled for the first time in college in fall 2006 (the year prior to program implementation) for a sample total of over 2150 students. Approximately 64% were female, 36 % were males, over 60% were African American and Hispanic, and over 75% were first generation college students. Logistic regression was used to measure probability and odds of their academic success and retention in the first year of college utilizing gender, ethnicity, parental degree attainment, and program participation as the independent variables. The logistic regression models illustrated that participation in the program netted a consistently positive and significant …

An Emotional Business:  the Role of Emotional Intelligence in Entrepreneurial Success (open access)

An Emotional Business: the Role of Emotional Intelligence in Entrepreneurial Success

Successful entrepreneurial activity is important for a healthy economy and can be a major source of job creation. While the concept of entrepreneurship has been around for quite some time, researchers continue to explore the factors that underlie entrepreneurial performance. Specifically, researchers have sought to further examine why some entrepreneurial ventures are more successful than others. the concept of emotional intelligence (EI) has gained the attention of researchers and practitioners alike. Practitioners have realized that employees can no longer be perceived as biological machines that are capable of leaving their feelings, norms, and attitudes at home when they go to work. Researchers are embracing the concept of emotional intelligence because of its relationship with efficiency, productivity, sales, revenues, quality of service, customer loyalty, employee recruitment and retention, employee commitment, employee health and satisfaction, and morale. While there is considerable evidence documenting the effects of emotional intelligence on leadership performance, job performance in large firms, and educational performance, very little research has examined how emotional intelligence affects entrepreneurial performance and the variables that account for this relationship. Individuals in entrepreneurial occupations face business situations that necessitate unique skills and abilities in social interactions. Emotional intelligence has implications for entrepreneurial situations and …

A New Literary Realism: Artistic Renderings of Ethnicity, Identity, and Sexuality in the Narratives of Philip Roth (open access)

A New Literary Realism: Artistic Renderings of Ethnicity, Identity, and Sexuality in the Narratives of Philip Roth

This dissertation explores Goodbye, Columbus and Five Short Stories (1959), the Ghost Writer (1979), the Counterlife (1986), the Facts (1988), Operation Shylock (1993), Sabbath's Theater (1995),and the Human Stain (2000), arguing that Roth relishes the telling of the story and the search for self within that telling. with attention to narrative technique and its relation to issues surrounding reality and identity, Roth's narratives stress unreliability, causing Roth to create characters searching for a more complex interpretation of self. Chapter I examines Roth’s negotiation of dual identities as Neil Klugman in Goodbye, Columbus feels alienated and displaced from Christianized America. the search for identity and the merging of American Christianity and Judaism remain a focus in Chapter II, which explores the implications of how, in the Ghost Writer, a young Nathan Zuckerman visits his mentor E.I. Lonoff to find him living in what he believes to be a non-Jewish environment—the American wilderness. Chapter II also examines the difficulties of cultural assimilation in "Eli, the Fanatic," in which Eli must shed outward appearances of Judaism to fit into the mostly Protestant community of Woodenton. Relative to the negotiation of multiple identities, Chapter III considers Sabbath’s attempt, in Sabbath’s Theater, to reconcile his …

Childhood Bereavement and Parents’ Relationship With Children (open access)

Childhood Bereavement and Parents’ Relationship With Children

It has long been recognized that childhood bereavement is a risk factor for depression in adulthood. Research also has consistently demonstrated that parental depression is linked to poor parent-child relationship quality. The current study examined whether bereavement in childhood increases likelihood of current depressive symptoms among parents and explored whether this vulnerability in the parent then alters the quality of the parent-child relationship. Archival data for a sample of 86 families (N=176 parents) are drawn from the Family & Kid Connection project led by Dr. Shelley Riggs. Instruments utilized include the Background Information Questionnaire, the Symptom Assessment-45 Questionnaire, and the Parenting Relationship Questionnaire. Using the Actor-Partner Interdependence Model, Multilevel Modeling procedures explored the hypothesis that parental depression mediates the association between parents’ childhood bereavement and their perception of the parent-child relationship. Results show a significant relationship between parental (actor) depressive symptoms and parent-child attachment, indicating the need for therapeutic interventions targeting the parent-child relationship, and not just parents, for parents suffering from depression.

Examining the Engagement of Transfer Students in Texas Universities (open access)

Examining the Engagement of Transfer Students in Texas Universities

The success of transfer students plays a critical role in improving the baccalaureate attainment rates of undergraduates attending 4-year higher education institutions in Texas; however, current indicators suggest transfer students have lower persistence and graduation rates relative to students who begin and complete their college education at one university (i.e., non-transfer students). Additionally, the research literature indicates a link between degree completion and engagement; however, transfer students are reported to be less engaged and less likely to persist than their counterparts. This quantitative study compared the engagement experiences of 2-year transfers, 4-year transfers, swirl transfer, and non-transfers by using National Survey of Student Engagement (NSSE) 2008 data to determine if there are any differences among these groups, and if these differences persist after controlling for individual and institutional covariates. the sample consisted of 2,000 seniors attending 4-year higher education institutions in Texas. the engagement scores of each group were compared using a multivariate analysis (MANOVA). This study found non-transfers were more engaged than each type of transfer student on Student-Faculty Interaction and Supportive Campus Environment factors; moreover, these differences generally persisted after controlling for residence, enrollment status, and institutional control (i.e., public vs. private).The data indicated no difference among the …

Western Media Attitudes Toward an Immigrant of Color Sex Crime Victim: Case Study: the DSK Case (open access)

Western Media Attitudes Toward an Immigrant of Color Sex Crime Victim: Case Study: the DSK Case

About 30 million women in the U.S. are estimated to be victims of sex crimes in their lifetimes. However, sex crimes, especially those committed against immigrants are the least reported crime in the country. Some sex crime victims say the fear of media criticism discourages them from reporting the crime. in May 2011, an African maid working at a New York hotel accused Dominique Strauss-Kahn, the former director of the International Monetary Fund, of sexually assaulting her. This qualitative content analysis examined the coverage of the DSK case, by three leading international newspapers: the New York Times, the Guardian and Le Monde. Findings suggest that Strauss-Kahn received more favorable coverage than Diallo. Frames identified in the coverage include the importance of status/prominence, race, culture differences, victim-blaming, male privilege, socioeconomic differences and focus on appearance. the study recommends that news organizations avoid judgmental coverage of sex crimes and consider identifying victims by allowing them to tell their side of the story.

Examining Visual Art Experiences for Relationship Building in Shared-site Locations (open access)

Examining Visual Art Experiences for Relationship Building in Shared-site Locations

This study explored the perceptions of 74 activity directors responsible for the intergenerational programming that is currently taking place at shared-sites, facilities where older adults and young people receive services and programs simultaneously in a co-located space. Data for this study was collected through a national survey of 149 shared-sites collected from the Generations United data base. the questionnaire asked respondents about their facility’s intergenerational programming, demographic information, and perceived sense of community exhibited by participants in the intergenerational program. Descriptive data regarding the location, primary emphasis, ages and number served, and specific program characteristics, including visual art programming, at IGSS facilities were collected and analyzed. Results from the analysis were reported with limitations. There was a statistical significance suggested in the association of the frequency and duration of art activities with some of the sense of community variables. the study is valuable in determining the current demographics of IGSS facilities that offer visual art programs. Further research needs to be conducted to answer questions regarding the specific role that the visual arts play in creating a sense of community among intergenerational participants at shared-site facilities.

Metamodeling-based Fast Optimization of  Nanoscale Ams-socs (open access)

Metamodeling-based Fast Optimization of Nanoscale Ams-socs

Modern consumer electronic systems are mostly based on analog and digital circuits and are designed as analog/mixed-signal systems on chip (AMS-SoCs). the integration of analog and digital circuits on the same die makes the system cost effective. in AMS-SoCs, analog and mixed-signal portions have not traditionally received much attention due to their complexity. As the fabrication technology advances, the simulation times for AMS-SoC circuits become more complex and take significant amounts of time. the time allocated for the circuit design and optimization creates a need to reduce the simulation time. the time constraints placed on designers are imposed by the ever-shortening time to market and non-recurrent cost of the chip. This dissertation proposes the use of a novel method, called metamodeling, and intelligent optimization algorithms to reduce the design time. Metamodel-based ultra-fast design flows are proposed and investigated. Metamodel creation is a one time process and relies on fast sampling through accurate parasitic-aware simulations. One of the targets of this dissertation is to minimize the sample size while retaining the accuracy of the model. in order to achieve this goal, different statistical sampling techniques are explored and applied to various AMS-SoC circuits. Also, different metamodel functions are explored for their …
