Reliability Analysis For Chain Topology Wireless Sensor Networks With Multiple-Sending Transmission Scheme, Jie Cai, Xiaoyu Song, Jinyuan Wang, Ming Gu

Electrical and Computer Engineering Faculty Publications and Presentations

Reliability analysis is a key problem in wireless sensor networks (WSNs). The primary contribution of this paper is an in-depth study of the reliability of a chain topology wireless sensor network with multiple-sending scheme. We study the wireless link reliability for the fading channels. The node energy availability for the source and relay nodes is investigated in terms of the limited node energy. The instantaneous network reliability and the mean time to failure are derived. Finally, the initial node energy allocation scheme is proposed to balance the lifetime of each sensor node, thus reducing the total energy consumption. The simulation …

A Consideration Of Tracking Within A Bounded Educational System, Scott David Ripley

Walden Dissertations and Doctoral Studies

American education is built upon a cultural paradigm of equality and access. Tracking students into homogenous classes based on prior academic performance could disadvantage lower-achieving students, thereby reinforcing inequality. The problem in the study district is that homogenous tracking was implemented, yet the system had not been evaluated within the context of implementation. The purpose of this qualitative case study was to examine educators' perceptions of the practice of tracking. Bandura and Maslow's social cognitive theory provided the conceptual framework and Dewey's beliefs on social justice and a spirit of equity provided the theoretical foundation. Open-ended narrative questionnaires were disseminated …

Refining Computerized Physician Order Entry Initiatives In An Adult Intensive Care Unit, Chevita Fuller

Walden Dissertations and Doctoral Studies

Computerized physician order entry (CPOE) is used in healthcare organizations to improve workflow processes and transcription, as well as to prevent prescribing errors. Previous research has indicated challenges associated with CPOE for end-users that predispose patients to unsafe practices. Unsafe CPOE practices can be detrimental within the intensive care unit (ICU) setting due to the complexity of nursing care. Consequently, end-user satisfaction and understanding of CPOE and electronic health record (EHR) functionality are vital to avoid error omissions. CPOE initiatives should be refined post system implementation to improve clinical workflow, medication processes, and end-user satisfaction. The purpose of this quality …

Symbolic Imprisonment, Grief, And Coping Theory: African American Women With Incarcerated Mates, Avon Marie Hart-Johnson

Walden Dissertations and Doctoral Studies

African American men have been incarcerated at unprecedented rates in the United States over the past 30 years. This study explored how African American females experience adverse psychosocial responses to separation from an incarcerated mate. The purpose of this qualitative grounded theory (GT) study was to construct a theory to explain their responses to separation and loss. Given the paucity of literature on this topic, helping professionals may not understand this problem or know how to support these women. Disenfranchised grief and the dual process model of bereavement were used as a theoretical lens for this study. Data were collected …

A Correlational Analysis Of Empowerment And Experience With Resistance To Change, Rita Elizabeth Burgess

Walden Dissertations and Doctoral Studies

Despite more than 60 years of research about the nature of change, resistance to change remains a problem across industries. Health care leaders have limited knowledge of how health care managers' perceptions of empowerment, years of experience, and resistance to change (RTC) relate. The purpose for this nonexperimental correlational study was to examine the relationship between empowerment, years of experience, and RTC among managers via an online survey. The theoretical framework incorporated Kanter's structural empowerment theory and Kotter's change theory. The sample included 245 out of 1,181 health care managers from Veterans Administration (VA) hospitals in the New York metropolitan …

Student Self-Efficacy In Employment Interviews: An Assessment Of A Communication Course Redesign, Jeralyn L Faris

IMPACT Symposium

Communication instruction and practice that increases a student’s self-efficacy in the employment interviewing process is a desired outcome of COM 325, Interviewing Principles and Practices. Self-efficacy outcomes are in the affective domain of Bloom’s Taxonomy and are measureable. Therefore, our study seeks to discover whether increasing time spent in individual performances of in-class employment interviews from 22 to 44 minutes increase students' self-efficacy in their interview performance ability.

Fourteen sections of COM 325 are offered Spring, 2014. Five of these sections are piloting a redesigned version of the course, via Purdue’s IMPACT initiative. The key difference in the five redesigned …

Disease Interpretations And Response Among Hiv-Positive Mothers, Johanna Debora Imelda

Antropologi Indonesia

Despite the growing number of new cases of HIV and AIDS in Indonesia, the progress of prevention programs has been slow. Low prevelance is always stated as a reason for delaying HIV prevention programs and to justify slow progress in implementation. Prevention programs are moreover based on a high-risk group paradigm. They focus on female sex workers as responsible for the spread of HIV, leading to its stigmatization as a hooker's disease. This article describes how seropositive mothers interpret and respond to HIV and AIDS as women, in light of the fact that most of them have not experienced full-blown …

Rasionalisasi Sakit Dan Penyakit Dalam Konstelasi Budaya Minangkabau (Kajian Etnomedisin Di Agam Dan Tanah Datar), Yunarti -, Nurainas -, Yulkardi -, Fitria Ramona

A medical system whether traditional or modern, is a long chain of processes of humanstrategy for adapting to their ecological bio-cultural environment. Naturally humans developtheir biological ability to sustain their kind and develop many adaptation strategies, creatingmedical systems, behavior, and belief sbased on culture as a natural response to the treat ofillness and disease, even though the result of certain behavior does not guarantee the healingof such illness and disease (Dunn in Foster-Anderson, 1986; p.41). under that circumstances,Minangkabau medical systems are seen as a result of a bio-eco-culturally adapting process.Local Etiology of the disease source is closely related to the …

Monitoring Brown Fat Metabolic Activity Using Microwave Radiometry: Antenna Design And Frequency Selection, Dario B. Rodrigues, Paul R. Stauffer, Paolo F. Maccarini

Department of Radiation Oncology Faculty Papers

This paper describes the use of microwave radiometry for monitoring brown fat metabolism (mBAT). The radiometric frequency band and receive antenna were optimized for coupling to 2-6 ml BAT depots in the supraclavicular region. Radiometric signal variations induced by higher metabolic activity resulting from a cold stimulus were calculated with electromagnetic and thermal simulations in a segmented computational model of the human neck including BAT. A 2.5 cm dia. log spiral antenna was selected as optimum using a 500 MHz bandwidth and center frequency 2.75 GHz. Results suggest sufficient sensitivity to track subsurface temperature variations during long term mBAT monitoring …

The Decline Of Civil Jury Trials: A Positive Development, Myth, Or The End Of Justice As We Now Know It?, Xavier Rodriguez

St. Mary's Law Journal

Jury participation is helpful in many respects. It fosters an understanding of the third branch of government and the workings of the judicial system. It offers the opportunity for individuals to serve in a unique role: neutral factfinder. Moreover, in an age of declining voter participation, jury service provides individuals with the opportunity to directly participate in our governmental structure. Despite these positive attributes, jury trials as we knew them are on the decline. That may or may not be problematic, depending on what types of cases are being impacted. Where parties have reached a voluntary and informed settlement on …

Drinking Buddies: Who Are They And When Do They Matter?, Cathy Lau-Barraco, Ashley N. Linden

Psychology Faculty Publications

The present study sought to further examine the role of peers on alcohol use and problems among young adults. In particular, we focused on a specific subset of peers in one's social network mostly for activities related to alcohol use called "drinking buddies." The presence of drinking buddies in one's social network has been shown to predict heavy drinking uniquely over time but few studies have focused on potential factors moderating the relationship. Consequently, an aim of present study was to examine the influence of drinking buddies on alcohol outcomes and the extent to which the relationship may be dependent …

Caffeinated Alcohol Consumption Profiles And Associations With Use Severity And Outcome Expectancies, Cathy Lau-Barraco, Robert J. Milletich, Ashley N. Linden

Psychology Faculty Publications

Growing evidence suggests that the consumption of caffeinated alcoholic beverages (CAB) may be riskier than alcohol alone. Efforts to identify patterns of CAB use and the correlates of such drinking patterns could further our conceptualization of and intervention for this health issue. Consequently, the current study aimed to (1) identify distinct classes of CAB users, (2) examine differences between classes on measures of alcohol and caffeine problems, and (3) compare distinct classes of CAB users on caffeine and alcohol outcome expectancies. Participants were 583 (31% men) undergraduate students from a psychology research pool. Latent profile analysis models were derived using …

How Patients' Self-Disclosure About Sickle Cell Pain Episodes To Significant Others Relates To Living With Sickle Cell Disease, Valerian J. Derlega, Louis H. Janda, Jeannie Miranda, Ian A. Chen, B. Mitchell Goodman Iii, Wally Smith

Psychology Faculty Publications

Objectives: This cross-sectional study examines to whom and how fully sickle cell disease (SCD) patients talk to others about sickle cell pain, how helpful it is to talk with others about these pain episodes, and the association between talking to others about sickle cell pain episodes and patients' psychological adjustment and coping strategies in managing the disease.

Methods: A convenience sample of 73 African American patients with SCD (30 men and 43 women), were recruited from two SCD clinics at the time of routine medical visits. Most participants had been diagnosed with hemoglobin SS, and they reported an average number …

Protective Behavioral Strategies, Alcohol Expectancies, And Drinking Motives In A Model Of College Student Drinking, Ashley N. Linden, Cathy Lau-Barraco, Robert J. Milletich

Psychology Faculty Publications

An extensive body of research asserts alcohol expectancies, or beliefs regarding the effects of alcohol, as an important influence on drinking. However, the extent to which expectancies are related to drinking motives and protective behavioral strategies (PBS) has yet to be examined. Existing alcohol mediational models suggest associations between expectancies and drinking motives as well as positive drinking motives and PBS use. Thus, it is possible that drinking motives and PBS use act as intervening factors in the relationship between expectancies and alcohol outcomes. Consequently, the cross-sectional study presented here aimed to test the indirect effect of expectancies (i.e., social …

Substance-Abusing Mothers And Fathers' Willingness To Allow Their Children To Receive Mental Health Treatment, Michelle L. Kelley, Gabrielle M. D'Lima, James M. Henson, Cayla Cotton

Psychology Faculty Publications

The purpose of this study was to examine attitudes of substance-abusing mothers and fathers entering outpatient treatment toward allowing their children to participate in individual- or family-based interventions. Data were collected from a brief anonymous survey completed by adults at intake into a large substance abuse treatment program in western New York. Only one-third of parents reported that they would be willing to allow their children to participate in any form of mental health treatment. Results of chi-square analyses revealed that a significantly greater proportion of mothers reported that they would allow their children to participate in mental health treatment …

Profiles Of Binge Eating: The Interaction Of Depressive Symptoms, Eating Styles, And Body Mass Index, Tyler B. Mason, Robin J. Lewis

Psychology Faculty Publications

Binge eating is associated with depressive symptoms, eating styles, and obesity. However, less is known about interactions between these variables and binge eating. This study examined the relationship between depressive symptoms, eating styles, body mass index, and binge eating. Individuals with a higher body mass index, who reported more depressive symptoms and more external eating, reported the greatest binge eating. Similarly, individuals with a higher body mass index who reported more depressive symptoms and more emotional eating reported the greatest binge eating. These findings demonstrate possible profiles of individuals most at risk for binge eating and associated eating disorders. Copyright …
