Bibliography: leaves 48-53. / The aim of this dissertation was to investigate the practice of clinical psychology in the Western Cape. This exploratory study described biographical information, characteristics, activities, and the nature of satisfaction and stress experienced. In addition, it established the degree of burnout experienced within this community, and investigated the interrelationships between job satisfaction, job stress and burnout. The sample consisted of 90 practicing clinical psychologists registered with the Professional Board for Psychology of the South African Medical and Dental Council. A questionnaire which was designed to elicit the above-mentioned information and consisted mainly of multiple-choice-type questions was mailed to the participants. Results were quantitative in nature and were treated predominantly descriptively. The study suggested that burnout occurs in low to moderate degrees and was significantly related to age, marital status and type of clinical practice. Furthermore, it was found that therapeutic expertise seemed to be an important factor when considering the interrelationships between job satisfaction, job stress and burnout.

Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (PhD) in Community Psychology at the University of Zululand, South Africa, 2012. / The aim of this study was to investigate the emotional experiences of adolescents from single-parent families; the primary aim being to determine whether adolescents display emotional experiences that differ from those of adolescents from both-parent families (intact families). Literature reveals that single parenting is strongly associated with an increased risk of negative social, behavioural and emotional outcomes ( Callister, Burks, & Suart 2006; Ge, Conger, & Eelder, 2005). A quasi-experimental design was adopted for this study. A sample of one hundred learners in grade 12 at one of the Bizana senior secondary schools was selected for this study. Their ages ranged from 16yrs to 18yrs. Sample selection was purposive. Of the 100 learners that were selected, half of them were from-single-parent families and the other half was from both-parent families. Each of these learners was asked to complete a questionnaire that would objectively assess them on six dimensions of psychological well-being. Ryff’s 18 item psychological well-being questionnaire was used. The six dimensions of psychological well-being, namely autonomy (a), personal growth (pg), environmental mastery (em), purpose in life (pl), positive relations with others (pr) and self-acceptance (sa).

Submitted to the Faculty of Education In partial fulfilment of the requirements for the degree MAGISTER EDUCATIONIS In the Department of Educational Psychology and Special Education at the UNIVERSITY OF ZULULAND, 2003 / The primary objective of this study was to determine the nature of stress experienced by teachers in schools of industries and to determine whether there are significant statistically relevant differences in the stress levels and manifestations for teachers in mainstream education and schools of industry. Secondary aims were to determine whether variables such as the gender, age and experience play a role in the perceived levels of stress manifestations. A total of 106 teachers participated in this study. A total of 40 (37,7%) teachers came from the two schools of industry and 66 from the two mainstream schools. The teachers were asked to complete the Teachers Concerns Inventory which included a short demographic survey. Analysis of the variance revealed that teachers from schools of industries experience high levels of stress. Fifteen of the 40 teachers (37,5%) indicated that stress is a problem to them, while approximately half of the teachers (19 of the 40) indicated that the intensity of stress experienced, was higher than average. The study showed that teachers experience high levels of stress with regard to time management, work-related stressors, professional distress, discipline and motivation and professional investment as wel as high levels of stress manifestations with regard to emotional, fatigue, cardiovascular, gastronomic and behavioural manifestations. The results of this study indicated that there are no difference between the stress levels and stress manifestation for teachers in schools of industry and mainstream schools and that demographic variables do not play a significant role in the stress levels of teachers.

This applied dissertation study was designed to inform and advance knowledge by using a quantitative approach to determine if perceived parental stress in homeschooling parents varies as a function of age, income, education, and ethnicity. Previous research in the field of homeschooling has primarily been qualitative in nature, thus, leaving a gap in the research. Home schooling parents of K-6 grade children in South Florida districts were specified as the sample for the study. A perceived Stress Survey and demographic questionnaire were administered to 102 participants. Parental participants were male and female, all ethnicity, and ages 18 and older, who were homeschooling K-6th grade children in South Florida. Inferential statistics were used to draw conclusions from the sample tested. The Statistical Package for the Social Sciences (SPSS) 23.0 was used to code and tabulate scores collected from the survey and provide summarized values where applicable. Logistic regression analyses of variance (ANOVA) were used to evaluate the two Research Questions and hypotheses. Analysis of the primary data indicated that age, income, level of education, ethnicity and number of children homeschooled had no significant effect on perceived stress. Implication from findings suggests that behavioral characteristics of the child may mediate the relationship between stress and parental characteristics. The study is a valuable addition to the homeschooling research community as it aligns with and extends findings from previous research.

SABP2-interacting protein 428(SIP428) is a SIR2-type deacetylase, also called sirtuins. The SIP428 proteins belong to a family of NAD+-dependent deacetylase enzyme that was identified in tobacco. SABP2 is an important methyl esterase enzyme that catalyzes the conversion of methyl salicylic acid (MeSA) into salicylic acid (SA) during the pathogenic challenge. Accumulation of SA induces systemic acquired resistance (SAR), a broad-spectrum defense mechanism in other uninfected distal parts of the plant. Sirtuins play diverse roles in DNA repair, apoptosis, and stress responses. Cellular proteins are known to undergo posttranslational modifications such as methylation, phosphorylation, and ubiquitination. A more recent addition to the list is acetylation. Protein acetylation is a reversible modification that plays role in regulating transcription, activation, and deactivation of certain pathways by transferring acetyl group to lysine residues. This change neutralizes the positive charge of the amino group thereby affecting the biological function of the affected proteins. Preliminary research has shown that SIP428 is a non-histone deacetylase. To understand better about the role of SIP-428 in plant physiology and how it plays a vital role in SABP2 signaling pathway we will be using transgenic tobacco plant in which the expression of SIP 428 has been silenced/knocked down.

The purpose of this study was to induce an oxidative-stress adaptation in Listeria monocytogenes Bug600 (serotype 1/2a) and F1057 (serotype 4b) by pre-exposing to sublethal H2O2 and alkali-stress either singly or sequentially. Our findings show that the sequential pre-exposure of cells to pH 9 for 30 min treatment followed by 50 ppm H2O2 for 30 min at 37°C yielded the highest oxidative-stress resistant phenotypes of L. monocytogenes Bug600 and F1057. The sublethal H2O2 and sublethal alkali-stress induced oxidative-stress adaptations were completely reversible within 60 min at 37°C in the absence of such sublethal stress. However, the oxidative-stress adaptation induced at 37°C was stable at 4°C over a 24 h test period in both L. monocytogenes Bug600 and F1057. Future studies will focus on the potential cross-resistance of oxidative-stress adapted L. monocytogenes serotypes 1/2a and 4b to commonly used disinfectants and GRAS antimicrobials.

Gestational diabetes mellitus impacts between 3-10% of pregnancies, and increases the risk of pregnancy complications and lifelong health effects for mother and child (Bellamy, Casas, Hingorani, & Williams, 2009; Ross, 2006; Ryser Rüetschi et al., 2016). About half of cases occur without an evident risk factor (American College of Obstetricians and Gynecologists (ACOG), 1994; Dode & Santos, 2009). The present study was designed to examine possible psychophysiological connections linking psychological stress and stress reactivity, the magnitude of an individual’s response to stress, to blood sugar metabolization during mid-pregnancy between 24-28 weeks gestation. Participants were recruited from Sanford Health in Fargo, where patients underwent routine Oral Glucose Tolerance Testing (OGTT) a diagnostic assessment in which higher results indicate less blood sugar metabolization. They also completed a Virtual Trier Social Stress Task while psychological and physiological markers of stress reactivity were assessed. Additionally, maternal stress and stress reactivity were assessed using psychosocial questionnaires. There was support for proposed psychophysiological connections, including models in which positive associations between OGTT and maternal stress and anxiety were moderated by psychological stress reactivity. Results suggest that both the presence of stress and a women’s responses to that stress are influential over blood glucose metabolization during pregnancy. Continuing research in this area may have implications for improving outcomes of women at higher risk of GDM and other adverse pregnancy and perinatal outcomes.

The Intergovernmental Panel on Climate Change has predicted that there will be increases in precipitation and heat-induced drought events globally. Information on kale response to waterlogging is minimal. The purpose of this project was to identify the response of kale to three treatments of water stress: underwatering, overwatering, and waterlogging. Plant pigments analyzed displayed a varied response to underwatering and overwatering, with concentrations changing with maturity but with reductions and no changes, respectively, at full harvest maturity. Glucosinolate concentrations were also influenced by maturity and increased under waterlogging and underwatering but no differences with overwatering. Overall, water stress to any degree is not ideal for kale during production, but despite yield reductions, underwatering led to increases among phytonutrients, but increases are apparent and do not equate to increased absorption when consumed.
