Morphological And Physiological Changes In Laying Hens In Various Stages Of Non-Feed Withdrawal Molt, Ann Laster Mcdonald
Morphological And Physiological Changes In Laying Hens In Various Stages Of Non-Feed Withdrawal Molt, Ann Laster Mcdonald
Theses and Dissertations
Molting is a natural occurrence in the Avian species that can include a period of fasting. Animal rights groups view the longepted standard industry practice as inhumane. Based on influences from these groups and the recommendation of its scientific committee, United Egg Producers (UEP) requires members of its Animal Care Certified Program use a noneed withdrawal molting program, even though the morphological and physiological effects of this method have not been studied in depth and the existing literature provides contradictory results. Research regarding how to induce a noneed withdrawal molt has been performed using feed that is nutrient deficient or …
Sense Of Humor, Stress And Coping, And Outcomes In Children's Lives, Lambertha Okhuizen-Stier Phd, Mph, Rn
Sense Of Humor, Stress And Coping, And Outcomes In Children's Lives, Lambertha Okhuizen-Stier Phd, Mph, Rn
Dissertations
Children are confronted with many stressors in their environment which may bring about symptoms such as anxiety, sadness, worry, aggressiveness, hyperactivity, restlessness, or low self esteem (Sharrer & Ryan-Wenger, 2002). To prevent the short and long term effects of stress, children may use coping strategies to manage or alter stressful life events (Lazarus & Folkman, 1984). This study explores the relationships between stress and sense of humor among school-age children. A sample of 106 students (and parents/guardians) in the San Diego Unified School District (SDUSD) returned self-report instruments packets containing the Multidimensional Sense of Humor Scale for Children, and the …
A Stressor-Strain Model Of Organizational Citizenship Behavior And Counterproductive Work Behavior, Kimberly E. O'Brien
A Stressor-Strain Model Of Organizational Citizenship Behavior And Counterproductive Work Behavior, Kimberly E. O'Brien
USF Tampa Graduate Theses and Dissertations
Prior research has attempted to develop a model of organizational citizenship behaviors (OCB) and counterproductive work behaviors (CWB), but limited testing remains a problem. The purpose of the current study is to examine OCB and CWB from a job stressor-strain approach. The sample consisted of 235 employees throughout the United States and their supervisors. Results of the study suggested OCB and CWB are affected by stressors (including interpersonal conflict, low interactional justice, job demands, and organizational constraints). Additionally, trait emotion and attributional styles affect the amount of stressors perceived. The implications as well as limitations of the study are discussed.
Strong Black Woman Cultural Construct: Revision And Validation, Dhakirah Amelia Hamin
Strong Black Woman Cultural Construct: Revision And Validation, Dhakirah Amelia Hamin
Psychology Dissertations
The purpose of the current study is to revise the wording of the items in the Strong Black Woman (SBW) attitudes scale and investigate the psychometric properties of this revised scale (renamed the SBW Cultural Construct Scale, SBWCCS). Another goal is to determine if the scale predicts racial identity, stress, and social support. The sample consisted of 152 women of African descent, who were recruited from a community based organization. An exploratory factor analysis on the SBWCCS scale suggested a 3-factor model consisting of (1) caretaking, (2) affect regulation, and (3) self-reliance. These factors parallel those found in the original …
Sticking It To The Man By Standing By Your Man: Social Support As An Act Of Resistance , Andrew Middleton Wallace
Sticking It To The Man By Standing By Your Man: Social Support As An Act Of Resistance , Andrew Middleton Wallace
University of New Orleans Theses and Dissertations
The purpose of this paper is to synthesize literatures on stress, social support, symbolic interaction, and de Certeau as they pertain to the recovery of a homosexually-identified individual from a homophobic interaction. A model of the initial stressful interaction as well as the interaction between a homosexually-identified individual and his socially-supportive network is posited with the consumption of culturally-disseminated roles and the salience of role-identities as the mechanisms by which it works. The model is then considered as a form of resistance in the light of broader gay liberation social movements. The study focuses on white, middle-class, American, homosexually-identified males …

Yoga As An Intervention For Stress Reduction And Enhanced Wellbeing In African American Athletes, Jennifer Fallon
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study explored the preventive impact of a brief Hat ha yoga program on stress-reduction and enhanced wellbeing in a sample of healthy African American college athletes. African Americans suffer higher rates of hypertension and sudden cardiac death syndrome, both linked to stress. Study design was single case, with six replications, utilizing comparison of pre- and post-intervention scores on physiological and psychological indicators of distress and wellbeing. Findings were inconsistent across participants and measures, though generally included beneficial increases in positive affect (i.e ., C = 0.567 , Z = 2 071, p < 0.05) and perceived physical health (i.e., C = 0489, Z = 1. 721, …

Coping With Perceived Racial And Ethnic Discrimination In Women Of Color In Graduate Education, Priti Shah
Counseling and Psychological Services Dissertations
How one perceives and copes with such experiences in graduate education can have profound impact upon the personal and professional experiences of minority women in higher education. This study utilized a grounded theory approach (Glasser & Strauss, 1967; Cresswell, Fassinger, 2005) to investigate the impact of perceived racial and ethnic discrimination occurring in academia and effective methods of coping with perceived racial/ ethnic discrimination among 10 women of color in graduate education. Data sources included individual interviews and a group interview meeting. This study allowed women of color who have felt marginalized to experience a sense of connectedness as they …
An Exploration Of The Stressors, Coping Resources, And Resiliency Of Rural Mothers Of Children With Special Needs, Claudia D. Brasfield
An Exploration Of The Stressors, Coping Resources, And Resiliency Of Rural Mothers Of Children With Special Needs, Claudia D. Brasfield
Counseling and Psychological Services Dissertations
A child with a severe disability intensifies the demands facing a family (Beck, Hastings, Daley, & Stevenson, 2004; Martin & Baker, 2001; Withers & Bennett, 2003). Mothers specifically face an intense challenge, a concern as a mother’s wellbeing directly impacts her child’s emotional well-being (Kobe & Hammer, 1994), physical development, and progress within treatment (Lessenberry & Rehfeldt, 2004). These challenges are further heightened for women living in rural communities as little has changed for individuals with disabilities in rural communities over the past twenty years (Letvak, 2002). Although heightened stress among these mothers is significant, it is unclear how best …
Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem
Investigating The Effects Of Tactile Stress On A Military Touniquet Application Task, Razia Nayeem
Electronic Theses and Dissertations
In combat, soldiers encounter stress from multiple sources including loss of sleep, extremely high levels of physical and psychological discomfort, extended periods of increased vigilance, and intense danger. Therefore, it is imperative to train such personnel on how to cope with these stressors. One way to do this is to include stressors in different forms of training to acclimate soldiers to the subsequent stress of combat. Due to their advantages, tactile trainers are being investigated increasingly for the use of training Army medics in this context. The present work examines how vibrating tactile sensors, or tactors, can be used as …
The Steroid Sulfatase Inhibitor (P-O-Sulfamoyl) - Tetradecanoyl Tyramine (Du-14) Enhances Memory Retention In Passive Avoidance In Rats With Hippocampal Cholinergic Deficit, Phebian Arinola Abitoye
The Steroid Sulfatase Inhibitor (P-O-Sulfamoyl) - Tetradecanoyl Tyramine (Du-14) Enhances Memory Retention In Passive Avoidance In Rats With Hippocampal Cholinergic Deficit, Phebian Arinola Abitoye
Electronic Theses and Dissertations
Neurosteroids, such as dehydroepiandrosterone sulfate, (DHEAS) are steroidal compounds synthesized within the central nervous system that modulate its function. Among the effects associated with sulfated neurosteroids is the enhancement of memory. Previous studies have demonstrated that altering the metabolism of neurosteroids via inhibition of the enzyme steroid sulfatase could reverse scopolamine-induced amnesia. p-O-(Sulfamoyl) - tetradecanoyl tyramine (DU-14) is a steroid sulfatase inhibitor (SSI) that prevents the conversion of DHEAS to DHEA thereby increasing the concentration of sulfated neurosteroids to potentiate the effect of endogenous DHEAS. To determine whether DU-14 could enhance memory retention for footshock in rats with hippocampal cholinergic …

Developing Higher Consciousness: The Effects Of Mantra Meditation On The Development Of Self-Actualizing Qualities In Teachers, Lisa M. Klein
Electronic Theses and Dissertations
This qualitative study focuses on teachers ranging from the elementary to secondary level who have practiced mantra meditation for at least three years while also teaching. By utilizing the methodology of portraiture, this study endeavored to determine if the practice of mantra meditation creates self-actualizing qualities in teachers, how teachers who practice mantra meditation perceive their response to stress and conflict in the classroom, and how teachers who practice mantra meditation perceive the effects of meditation on their personal and professional lives. The methodology of portraiture was chosen because according to Lawrence-Lightfoot, "with its focus on narrative, with its use …

Passive Integrated Transponders In Gila Elegans: Location, Retention, Stress, And Mortality, Andrea Dee Montony
UNLV Retrospective Theses & Dissertations
Despite large-scale propagation and rearing efforts few of the critically endangered bonytail, Gila elegans, are recovered following release from hatcheries. This study tested the role of passive integrative transponder (PIT) tag loss and tagging associated stress and mortality in these low recoveries. Bonytail exhibited 98-100 percent tag retention regardless of insertion direction (ventral toward anterior and anterior toward ventral). Plasma cortisol levels were measured at 0, 0.5, 3, 6, 12, and 24 hours following PIT-tagging in fish held at three temperatures (12, 16, and 20°C) as an indicator of stress. Bonytail tagged at 16°C had significantly lower plasma cortisol levels …

Adolescents' Stress And Health: Parental Influences And Cognitive Mediators, Reesa Donnelly
Adolescents' Stress And Health: Parental Influences And Cognitive Mediators, Reesa Donnelly
Electronic Theses and Dissertations
Research to date indicates that parental and cognitive variables play a role in stress responses and health outcomes. Although researchers are beginning to focus on developmental processes in stress/health outcomes, there is little research examining which parental behaviors are most predictive of stress/health and whether cognitive variables mediate this relationship. As a result, the current study examines the self-reports of 160 late adolescents regarding parental behaviors, cognitive variables, and stress/health outcomes. In addition, blood pressure reactivity to a stressful situation was collected as a physiological measure of stress. The results suggest that, among the parental behaviors that are examined, parental …

Maternal Corticosterone Influences On Fear Responses In Offspring Of Quail Divergent Stress Response Lines, Kyndal A. Davis
Maternal Corticosterone Influences On Fear Responses In Offspring Of Quail Divergent Stress Response Lines, Kyndal A. Davis
LSU Master's Theses
Increased fearfulness has been associated with adrenocortical activation. Maternal corticosterone (B) treatment increases egg yolk B, and elevated B in ovo enhances chick avoidance of humans. Quail selected for exaggerated (high stress, HS) as opposed to reduced (low stress, LS) plasma B response to stress are more fearful, and more B is found in the egg yolks of HS than LS hens. Therefore, the underlying fearfulness (tonic immobility, TI) and timidity (hole-in-the-wall box, HWB, emergence) responses were assessed in chicks hatched from eggs of LS and HS hens implanted with silastic tubes containing no B (CON) or B (B-IMPLANT) during …

Sources Of Workplace Stress And Levels Of Burnout In Counsellors, Sarah Marguerite Flynn
Digitized Theses
Individuals employed in occupations that involve an intense emotional element, such as counselling, are particularly affected by stress and burnout. This study established levels of counsellor burnout, compassion fatigue, and compassion satisfaction in 76 counsellors using the Professional Quality of Life Scale (ProQOL). Using both quantitative and qualitative means, this study examined how such variables as the domain of counselling, professional experience, case load, and the amount of engagement in self-care affect counsellors’ burnout levels. The counsellors in this sample were significantly less burned out and showed significantly more compassion satisfaction than the ProQOL normed sample. Furthermore, burnout and compassion …

Browse all Theses and Dissertations
This study compared the effects of centrally and peripherally administered oxytocin (OT) on HPA axis activity and the presence of both stress-induced active and passive behaviors in female guinea pig pups (Cavia porcellus) after 180-min of isolation . In Experiment 1, one dose of oxytocin (10μg/.2ml) was injected subcutaneously into the periphery. Plasma cortisol levels were reduced after 180-min of isolation and two passive behaviors, eye-closure and crouch, were reduced as well with the administration of oxytocin. In Experiment 2, two different doses (10μg/.2ml and 20μg/.2ml) were injected into the periphery with no significant results. In Experiment 3 one dose …

Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt
LSU Master's Theses
Unstressed and stressed quail hens selected for exaggerated (HS, high stress) rather than reduced (LS, low stress) plasma corticosterone (B) response to brief restraint deposit more B into their eggs than do their LS hen counterparts. HS hens implanted with B also show reduced egg lay when compared to LS- and HS-control and LS-B-implanted hens. Herein, the effects of stress line on length of egg incubation (LEI) and chick body weight at emergence (BWTE) (Exp. 1) and the interactive influences of line with maternal B-treatment (sub-Q control, CON-, or B-implants) on LEI (Exp. 2) and on egg fertility (FERT), total …
