Etologicamente, os animais expressam repostas de medo frente a um predador ou a um co-especifico e a organização neural de respostas defensivas intraespecíficas são pouco conhecidas. Assim, o objetivo deste trabalho foi estudar o papel hipotalâmico na organização da defesa intraespecífica. Observamos que o núcleo pré-mamilar dorsal do hipotálamo também está ativo durante nesse tipo de defesa, porém porções distintas do mesmo. A lesão desse núcleo em ratos expostos a derrota social levou a importantes alterações comportamentais, praticamente abolindo comportamentos de defesa passiva. Notamos que regiões do hipotálamo lateral são as principais projeções aferentes do núcleo pré-mamilar dorsal e o principal alvo eferente é a coluna dorsomedial da matéria cinzenta periaquedutal. Concluímos que o hipotálamo é fundamental para a organização da defesa intraespecífica e que comportamentos defensivos inter e intra-específicos se utilizam de caminhos neurais distintos. / In nature, animals express fear responses toward a predator or a co-specific and not much is known about the neural organization of intra-specific defense. Therefore, the aim of this work was to analyze the role that the hypothalamus plays during the intra-specific defense expression. We observed that the dorsal premammilary nucleus is also mobilized during the agonistic encounter, but a different portion. Dorsal premammilary nucleus lesioned intruders led to important defense alterations, almost abolishing passive forms of defensive behavior. Notably, regions in lateral hypothalamus are particularly important for activating the dorsal premammilary nucleus and its efferent projection to the dorsomedial column of periaqueductal gray matter is the most important outcome for the defensive behavior expression. Concluding, the hypothalamus is fundamental for the neural organization of intra-specific defense and inter and intra-specific defensive behaviors are organized by distinct neural pathways.

Onion thrips (Thrips tabaci) and Iris Yellow Spot Virus (IYSV) constitute a pest complex of global concern for allium growers. Yield losses due to onion thrips alone can be heavy, and in tandem with IYSV, these losses can be complete. This study was one phase of a multi-phase research project intent on exploring the potential drivers of thrips and virus infestation in onion. Preliminary observations in participating growers’ fields in northern Utah pointed towards a potential link between weedy field borders and thrips/IYSV infestation in onion. Field work was carried out at the Kaysville experiment station examining the possible relationships between thrips and IYSV incidence in onion and the presence of adjacent weed populations. This research was conducted with the intent of guiding growers’ decisions regarding field border management, and to provide additional insights into onion thrips behavior. While implications for growers remain unclear, thrips preferences regarding host plant utilization were identified, as well as preliminary evidence of additional plant species capable of hosting IYSV.

Over the last decade, long-term care facilities have transitioned from institutional care models that focus on person-centered care, in which the resident is the center of the care. The purpose of this study is to explore the nurse and certified nursing assistant perception of the person-centered care services they deliver. Jean Watson's theory of human caring is the theoretical framework that guided this study. The theory focusing on the human caring experiences and person-centered care is being characterized as a caring feeling. The carative factors of Watson's theory, the fundamental concept of caring, has been associated with improved outcomes for the resident and the caregiver. Using a phenomenology research design, 3 focus groups of 15 nurses and 10 certified nursing assistants (CNA), working in a long-term care facility, were asked questions to describe their perception of person-centered care. The responses from the 25 participants were stored and organized using Nvivo. The thematic analysis revealed that the nurses and CNAs perceived person-centered care to include the caring and compassionate approach taken when care is being delivered. The participants also shared that person-centered care included involving the resident in decision making through communicating openly and developing relationships. The discussions revealed that 8 carative factors influenced their understanding, with the main factor being the creative problem-solving method for decision making. The �ndings from this study have the potential to impact positive social change at the organizational level, influencing the delivery of care within long-term care settings.

This thesis investigates estrogens' modulation of three aspects of social cognition (aggression and agonistic behaviour, social learning, and social recognition). Sex-typical agonistic behaviour (males: overt attacks, females: more subtle dominance behaviours) was increased in gonadectomized mice by estrogen receptor alpha (ERα) agonist 1,3,5-tris(4-hydroxyphenyl)-4-propyl-1H-pyrazole (PPT), while non-overt agonistic behaviour was increased in male and female gonadally intact mice by ERβ agonist 7-Bromo-2-(4-hydroxyphenyl)-1,3-benzoxazol-5-ol (WAY-200070). Estrogens also affected the social transmission of food preferences (STFP). Acute estrogen and ERβ agonists WAY-200070 and 2,3-bis(4-hydroxyphenyl)propionitrile (DPN) prolonged the preference for the demonstrated food when administered pre-acquisition, likely by affecting motivation or the nature of the social interaction, while acute PPT blocked the STFP. All mice receiving any of the three treatments chronically showed a prolonged demonstrated food preference, suggesting a loss of ER specificity. Individual differences in social recognition may relate to increased oxytocin (OT) and vasopressin (AVP) mRNA, and ERα and ERβ gene activation, in the medial preoptic area, and decreased mRNA for ERs, OT receptor (OTR), AVP and AVP receptors 1a and 1b in the lateral amygdala. Additionally, dorsolateral septum ERs, progesterone receptor, and OTR may relate to social interest without affecting social recognition. Our and others' results suggest that estrogens, OT and AVP are all involved in social behaviours and mediate social recognition, social learning, social interactions, and aggression. ERs differently modulate the two types of social learning investigated here: ERα is critical for social recognition, but impairs social learning, while ERβ is less important in social recognition, and prolongs the demonstrated food preference in the STFP. This may be due to differences in receptor brain distributions or in downstream neurochemical systems that mediate these behaviours. The results of this thesis suggest that estrogens, through the various systems they modulate, have a key role to play in social behaviour. Further investigations of how estrogens effect change in these systems at the molecular and cellular level, as well as the critical brain areas and downstream effectors involved in these complex behaviours, are needed, and could contribute to therapeutic interventions in socially-based, sexually dimorphic disorders, like the autism spectrum disorders, and women receiving hormone replacement therapy for negative peri- or post-menopausal symptoms. / National Science and Engineering Research Council (PGS-D, CGS-M)

In 1994 the new government introduced a subsidy scheme where the beneficiaries are provided with houses through housing projects. The houses have been vastly criticised for being small and poorly built. The sites provided are perceived to be small. The recreational facilities are perceived to be non existent and educational facilities scarce. The places where the projects are, is perceived to be far away from job opportunities. A sample of 200 beneficiaries was drawn from 1024 beneficiaries residing in the housing project in the area of France, Edendale in Pietermaritzburg, Phases 1 and 11. In this study, the respondents were composed of 32.9% males and 67.1% females. The respondent’s age group who participated in this project was 3.9% between 0-21 years, 28.9% between 22-35 years, 34.2% between 36-45 years, 16.4% between 46-55 years, and 11.8% between 55- 65 years and 4.6% did not reveal their age status. 80.9%, indicated they were owners of the houses, 6.6% indicated that they were not and those that did not reply are 12.5%. The study is descriptive in nature and explored the extent to which the beneficiaries were happy with their houses. The study explored the perceptions on the size of the sites, the small starter houses, the sanitation provided and the location of the houses. The findings suggest that the provision of sustainable housing in South Africa is still a challenge. The houses are still located far from the places of work and they are so small and there is overcrowding. The sizes of the sites are small and the sanitation provided unacceptable. The recreational facilities are nonexistent. Beneficiaries expressed dissatisfaction with the educational facilities. / Thesis (MBA)-University of KwaZulu-Natal, Westville, 2012.

Competition for seats in Canadian medical schools has driven many Canadians to seek medical education abroad. Systematic barriers make it necessary for internationally educated physicians (IEPs) hoping to practice in Canada to complete postgraduate residencies. To do so, they must transition into new medical education systems. The transitional experiences of internationally educated physicians are not well understood. This phenomenological qualitative study reveals the perspectives of twenty recent graduates from the University of Manitoba Family Medicine residency program. Canadians Studying Abroad constituted the majority of participants. Participant interviews revealed the presence of clinical practice gaps, created by curricular differences in the timing of graduated clinical responsibility between the Canadian and international medical education systems. Participants also shared their experiences of being singled out (visibility and invisibility), rejected and mistreated. They perceived that IEP residents were assigned low status in resident hierarchies. Their experiences are conceptualized as stigmatization.

This study examined the attitudes and perceptions of resident assistants towardgay, lesbian, bisexual, and transgendered (GLBT) students. Attitudes and perceptions of floor environments, hall environments, and the campus community were looked at. The original intent of this study was to find a relationship between resident assistants' attitudes and perceptions toward GLBT individuals and its relationship to the environment created on the RA's floor. The sample of GLBT students was too small to make reference to it in this study.A significant difference was found between hall staffs' attitudes. The study suggests that their hall environment can influence RAs' attitudes and perceptions. Consistent with past research, male resident assistants (RAs) had more negative views toward gay men and lesbians than female RAs. Inconsistent responses were found to individual questions, which suggests a lack of education on GLBT issues. The majority of RAs believed there should not be more GLBT material integrated in the classroom, however they felt they didn't have adequate training on GLBT issues. RAs felt that GLBT students experience less harassment and discrimination in the residence halls then on campus and in society. / Department of Secondary, Higher, and Foundations of Education

This study provides a compelling, comprehensive argument regarding how Resident Assistants (RAs) understand sexism at Ball State University. The evidence asserts gender privilege and sexism are prevalent on the campus. The findings substantiate that many RAs have witnessed instances, or become victims of sexism while at Ball State University. The evidence further demonstrates RAs value education on sexism for themselves and their residents. The findings indicate RAs both feel responsibility, and are expected to provide this education to residents. However, the evidence also illustrates RAs are in prime roles for promoting holistic learning but receive neither the appropriate training nor education needed to teach residents about sexism. Implementing training and education for RAs will decrease instances of, and misunderstandings about sexism. This will help faculty members, administrators, student affairs professionals, RAs, and others educate through prevention in order to best serve the students at Ball State University. / Department of Educational Leadership
