Relating leadership, thinking styles, self-concept, motivation and stress management in education

Seventy-five principals and vice-.wincipals from public elementary and secondary schools in Hamilton, Ontario, Canada participated in this study. Participants provided ,information concerning their thinking styles, motivations, and the physical effects of stress. This information was examined to find out how satisfaction-oriented, and how security-oriented the thinking styles of the participants were. Second, the data were analysed to see how the thinking style orientations related to life style habits and the effects of stress. The satisfaction-oriented thinking styles scored higher than all of the security-oriented thinking styles by a wide margin with a small preference for the satisfaction-people-oriented styles labelled humanistic-helpful, and affiliative as opposed to the satisfaction-task-oriented styles labeled achievement, and self-actualizing. Although all eight of the security-oriented thinking styles scored well below all of the satisfaction-oriented thinking styles on the Life Styles Inventory, the perfectionistic style scored higher than all of the security-oriented styles by an impressive margin. The next highest scores were recorded by a cluster of three passive-defensive people-oriented thinking styles labeled approval, conventional, and dependent. The competitive style scored lower, and the styles labeled avoidance, oppositional, and power scored the lowest of all the defensive-security-oriented styles. These findings suggest that principals and vice-principals see themselves as relaxed, flexible, and satisfied with their ability to adapt to the stress levels they experience in their lives; however, there was some support for medical research findings that suggest that specific security-oriented thinking styles are associated with emotional stresses that contribute to the development of specific lifestyle habits, physical symptoms, and illnesses. Although the number of females in this study provides very limited generalizability, the findings of this study suggest that high achieving females tend to develop satisfaction-growth styles to a higher level than males, and they tend to use security-oriented styles to a lesser degree than males.

The status of drama in education in an Ontario school board

Drama in education has been describea- as a valuable pedagogical medium and methodology, enriching child development in the cognitive, skill, affective, and aesthetic domains, and spanning all areas of curriculum ~ oontent. However, despite its considerable versatility and cost-effectiveness, drama appears to maintain low status within the education system of ontario. This thesis investigated teacher perceptions of both the value and status of drama in education in one ontario school board. Data were gathered in the form of an attitude questionnaire, which was devised for the purpose of this research and administered to a stratified cluster sample of 126 teachers employed in the board's elementary schools. These data were then used to examine teacher perceptions based on their knowledge, attitudes, and self-reported behaviour in the classroom. Teacher characteristics of gender, teaching assignment, years experience, and courses taken in drama were also analyzed as potential determinants of teacher attitudes towards drama in education. Results of the study confirmed apparent discrepancy between teacher perceptions of the value of drama and its current educational status. It was indicated that what teachers value most about drama is its capacity to enhance creativity, social skills, empathy, personal growth, and problem-solving ability among students. Teachers attribute its low status both to school and board priorities of time and resources, and to deficiencies in their knowledge and confidence in the planning, implementation, and evaluation of drama in the classroom. Teacher subgroup analysis revealed no significant differences in attitudes towards the status of drama in education; it did, however, suggest that both teachers who have studied drama and teachers with between ten and twenty years experience are most likely to value drama more highly than their colleagues. Recommendations proposed by the study include the provision of increased - time and resource allotment for drama within the elementary curriculum as well as increased teacher training at both faculty of education and board inservice levels.

Deconstructing Evidence-Based Practice and Its Application in Children to with Mental Health Disorders

This is a mixed methodology study that uses an autoethnographic approach to combine both an autobiography and a survey of practitioners who work in children’s mental health. It is largely about the implementation of Evidence-Based Practice (EBP), and the questions, concerns, experiences that I have had, and compared them with those of my fellow practitioners. In addition, it is about my journey as a mental health professional, and how I have come to recognize that in order to achieve the goals I wanted to achieve, I needed to return to university to pursue a Master’s degree. Within the research, I identify and discuss different definitions of EBP and identify several themes. I deconstruct the implementation of EBPs through the lens of Foucault and his notions of governmentality. I offer policy and practice recommendations to improve the implementation of EBP and the services received by children facing mental health issues.

Ethnic Minority Parents' Involvement in Education: Exploring and Understanding Their Experiences

Lopez, Scribner and Mahitivanichcha (2001) discuss the limited volume of literature that directly addresses ethnic minority parents' involvement in their children's education and they call upon researchers to fill this gap in the literature. This study is one such positive step with its focus on exploring how ethnic minority parents of secondary school students in southern Ontario understand their involvement in their children's education. Participants in the study included three ethnic minority parents recruited from a local adult education centre, and my parents who, as ethnics minority parents, also faced challenges trying to support their children as we progressed through the Ontario educational system. Primary data were collected through in-depth, open-ended interviews approximately one hour in length. Each of the five participants was interviewed twice. Secondary data included Ontario Ministry of Education documents that addressed programs, policies, and supports for ethnic minority students in Ontario secondary schools. Fieldnotes and a research journal also provided secondary data. The findings highlight, among other things, the challenges the participants faced as ethnic minority parents with a deep desire to support their children's education, but often lacking the cultural capital valued in the Ontario school system to meet that goal. As well, I benefited greatly from this research learning about the various ways in which, in my future work as a teacher of ethnic minority students, I can integrate the knowledge, skills, and experiences of ethnic minorities into my practice to ensure that parents of the non-dominant culture have an opportunity to become highly involved in the education of their children.

Narratives of Experience in Education: Living and Working Through Poverty in a Rural Community

In this study, I use my own experiences in education as a former elementary student, research assistant, and as a current secondary school teacher, to examine how living in a marginalised rural community challenged by poverty affected my formal education. The purpose of this study was to use stories to: (a) explore my formative elementary education growing up in a community that was experiencing poverty, and; (b) to examine the impact and implications of these experiences for me as a teacher and researcher considering the topic of poverty and education. This study used narrative inquiry to explore stories of education, focusing on experiences living and working in a rural community. My role in the study was both as participant and researcher as I investigate, through story, how I was raised in a marginalised, rural community faced with challenges of poverty and how I relate to my current role as a teacher working in a similar, rural high school. My own experiences and reflections form the basis of the study, but I used the contributions of secondary participants to offer alternative perspective of my interpretation of events. Participants in this study were asked to write about and/or retell their lived stories of working in areas affected by challenging circumstances. From my stories and those of secondary participants, three themes were explored: student authorship, teaching practice, and community involvement. An examination of these themes through commonplaces of place, sociality and time (Connelly and Clandinin, 2006) provide a context for other educators and researchers to consider or reconsider teaching practices in school communities affected by poverty.

Foster Children in Education: Resource Handbook for Elementary Educators

This project is aligned with examining the role of the education system and the foster care context on the learning experiences of young children in the classroom. This project is a study of the literature and research conducted on the life experiences, adverse effects of these experiences (such as attachment disorder), socioemotional development, and resiliency of foster care children. Furthermore, the project explores the literature on how the experiences of these foster children traverse contexts and impact the education setting. This study also outlines specific strategies and practices for teachers and school staff in order to promote students’ resiliency, competency, behaviour management, and overall educational success and positive academic experience. These strategies resulted from a critical review of the literature and translated into the development of an informative handbook intended for teachers. The handbook developed in this study focuses on the understanding of the lives of foster care children, their histories, adverse experiences, socioemotional development, strategies to manage behaviour, unique needs, and encouraging their resiliency and success in school. To ensure the soundness of the handbook, 2 education liaisons at a Family and Child Services agency within Ontario and a former child and service social worker from Manitoba reviewed the first draft and provided comments on the validity of the content and the potential usability of the handbook for educators. Suggestions and comments provided by these experts were used to enhance the final product of the handbook.

Cardiac cell fate control by the imidazoline I1 receptor/nischarin : application in cardiac pathology

La moxonidine, un médicament antihypertenseur sympatholytique de type imidazolinique, agit au niveau de la médulla du tronc cérébral pour diminuer la pression artérielle, suite à l’activation sélective du récepteur aux imidazolines I1 (récepteur I1, aussi nommé nischarine). Traitement avec de la moxonidine prévient le développement de l’hypertrophie du ventricule gauche chez des rats hypertendus (SHR), associé à une diminution de la synthèse et une élévation transitoire de la fragmentation d’ADN, des effets antiprolifératifs et apoptotiques. Ces effets se présentent probablement chez les fibroblastes, car l’apoptose des cardiomyocytes pourrait détériorer la fonction cardiaque. Ces effets apparaissent aussi avec des doses non hypotensives de moxonidine, suggérant l’existence d’effets cardiaques directes. Le récepteur I1 se trouvé aussi dans les tissus cardiaques; son activation ex vivo par la moxonidine stimule la libération de l’ANP, ce qui montre que les récepteurs I1 cardiaques sont fonctionnels malgré l’absence de stimulation centrale. Sur la base de ces informations, en plus du i) rôle des peptides natriurétiques comme inhibiteurs de l’apoptose cardiaque et ii) des études qui lient le récepteur I1 avec la maintenance de la matrix extracellulaire, on propose que, à part les effets sympatholytiques centrales, les récepteurs I1 cardiaques peuvent contrôler la croissance-mort cellulaire. L’activation du récepteur I1 peut retarder la progression des cardiopathies vers la défaillance cardiaque, en inhibant des signaux mal adaptatifs de prolifération et apoptose. Des études ont été effectuées pour : 1. Explorer les effets in vivo sur la structure et la fonction cardiaque suite au traitement avec moxonidine chez le SHR et le hamster cardiomyopathique. 2. Définir les voies de signalisation impliquées dans les changements secondaires au traitement avec moxonidine, spécifiquement sur les marqueurs inflammatoires et les voies de signalisation régulant la croissance et la survie cellulaire (MAPK et Akt). 3. Explorer les effets in vitro de la surexpression et l’activation du récepteur I1 sur la survie cellulaire dans des cellules HEK293. 4. Rechercher la localisation, régulation et implication dans la croissance-mort cellulaire du récepteur I1 in vitro (cardiomyocytes et fibroblastes), en réponse aux stimuli associés au remodelage cardiaque : norépinephrine, cytokines (IL-1β, TNF-α) et oxydants (H2O2). Nos études démontrent que la moxonidine, en doses hypotensives et non-hypotensives, améliore la structure et la performance cardiaque chez le SHR par des mécanismes impliquant l’inhibition des cytokines et des voies de signalisation p38 MAPK et Akt. Chez le hamster cardiomyopathique, la moxonidine améliore la fonction cardiaque, module la réponse inflammatoire/anti-inflammatoire et atténue la mort cellulaire et la fibrose cardiaque. Les cellules HEK293 surexprimant la nischarine survivent et prolifèrent plus en réponse à la moxonidine; cet effet est associé à l’inhibition des voies ERK, JNK et p38 MAPK. La surexpression de la nischarine protège aussi de la mort cellulaire induite par le TNF-α, l’IL-1β et le H2O2. En outre, le récepteur I1 s’exprime dans les cardiomyocytes et fibroblastes, son activation inhibe la mort des cardiomyocytes et la prolifération des fibroblastes induite par la norépinephrine, par des effets différentiels sur les MAPK et l’Akt. Dans des conditions inflammatoires, la moxonidine/récepteur aux imidazolines I1 protège les cardiomyocytes et facilite l’élimination des myofibroblastes par des effets contraires sur JNK, p38 MAPK et iNOS. Ces études démontrent le potentiel du récepteur I1/nischarine comme cible anti-hypertrophique et anti-fibrose à niveau cardiaque. L’identification des mécanismes cardioprotecteurs de la nischarine peut amener au développement des traitements basés sur la surexpression de la nischarine chez des patients avec hypertrophie ventriculaire. Finalement, même si l’effet antihypertenseur des agonistes du récepteur I1 centraux est salutaire, le développement de nouveaux agonistes cardiosélectifs du récepteur I1 pourrait donner des bénéfices additionnels chez des patients non hypertendus.

Extraction of Glucan from Acremonium Diospyri and Its Application in Macrobrachium Rosenbergii Larval Rearing System Along With Bacterians as Microspheres

Present work is aimed at development of an appropriate microbial technology for protection of larvae of macrobrachium rosenbergii from disease and to increase survival rate in hatcheries. Application of immunostimulants to activate the immune system of cultured animals against pathogen is the widely accepted alternative to antibiotics in aquaculture. The most important immunostimulant is glucan. Therefore a research programme entitled as extraction of glucan from Acremonium diospyri and its application in macrobrachium rosenbergii larval rearing system along with bacterians as microspheres. The main objectives of the study are development of aquaculture grade glucan from acremonium diospyri, microencapsulated drug delivery system for the larvae of M. rosenbergii and microencapsulated glucan with bacterian preparation for the enhanced production of M. rosenbergii in larval rearing system. Based on the results of field trials microencapsulated glucan with bacterin preparation, it is concluded that the microencapsulated preparation at a concentration of 25g per million larvae once in seven days will enhance the production and quality seed of M. rosenbergii.

Production and Characterization of Endocylanase from Bacillus Pumilus Using Solidstate Fermentation and its Application in 'Paper Pulp Processing

In the present studies it is clear that Bacillus pumilus xylanase is having the characteristic suited for an industrial enzyme (xylanases that are active and stable at elevated temperatures and alkaline pH are needed). SSF production of xylanases and its application appears to be an innovative technology where the fermented substrate is the enzyme source that is used directly in the bleaching process without a prior downstream processing. The direct use of SSF enzymes in bleaching is a relatively new biobleaching approach. This can certainly benefit the bleaching process to lower the xylanase production costs and improve the economics and viability of the biobleaching technology. The application of enzymes to the bleaching process has been considered as an environmentally friendly approach that can reduce the negative impact on the environment exerted by the use of chlorine-based bleaching agents. It has been demonstrated that pretreatment of kraft pulp with xylanase prior to bleaching (biobleaching) can facilitate subsequent removal of lignin by bleaching chemicals, thereby, reducing the demand for elemental chlorine or improving final paper brightness. Using this xylanase pre-treatment, has resulted in an increased of brightness (8.5 Unit) when compared to non-enzymatic treated bleached pulp prepared using identical conditions. Reduction of the consumption of active chlorine can be achieved which results in a decrease in the toxicity, colour, chloride and absorbable organic halogen (AOX) levels of bleaching effluents. The xylanase treatment improves drainage, strength properties and the fragility of pulps, and also increases the brightness of pulps. This positive result shows that enzyme pre-treatment facilitates the removal of chromophore fragments of pulp there by making the process more environment friendly

Intraseasonal oscillation of total precipitable water over North Indian Ocean and its application in the diagnostic study of coastal rainfall

TRMM Microwave Imager (TMI) is reported to be a useful sensor to measure the atmospheric and oceanic parameters even in cloudy conditions. Vertically integrated specific humidity, Total Precipitable Water (TPW) retrieved from the water vapour absorption channel (22GHz.) along with 10m wind speed and rain rate derived from TMI is used to investigate the moisture variation over North Indian Ocean. Intraseasonal Oscillations (ISO) of TPW during the summer monsoon seasons 1998, 1999, and 2000 over North Indian Ocean is explored using wavelet analysis. The dominant waves in TPW during the monsoon periods and the differences in ISO over Arabian Sea and Bay of Bengal are investigated. The northward propagation of TPW anomaly and its coherence with the coastal rainfall is also studied. For the diagnostic study of heavy rainfall spells over the west coast, the intrusion of TPW over the North Arabian Sea is seen to be a useful tool.
