Genetic variation and population structure of the endangered Hyacinth Macaw (Anodorhynchus hyacinthinus): implications for conservation

The Hyacinth Macaw (Anodorhynchus hyacinthinus) is one of 14 endangered species in the family Psittacidae occurring in Brazil, with an estimated total population of 6,500 specimens. We used nuclear molecular markers (single locus minisatellites and microsatellites) and 472 bp of the mitochondrial DNA control region to characterize levels of genetic variability in this species and to assess the degree of gene flow among three nesting sites in Brazil (Pantanal do Abobral, Pantanal de Miranda and Piaui). The origin of five apprehended specimens was also investigated. The results suggest that, in comparison to other species of parrots, Hyacinth Macaws possess relatively lower genetic variation and that individuals from two different localities within the Pantanal (Abobral and Miranda) belong to a unique interbreeding population and are genetically distinct at nuclear level from birds from the state of Piaui. The analyses of the five apprehended birds suggest that the Pantanal is not the source of birds for illegal trade, but their precise origin could not be assigned. The low genetic variability detected in the Hyacinth Macaw does not seem to pose a threat to the survival of this species. Nevertheless, habitat destruction and nest poaching are the most important factors negatively affecting their populations in the wild. The observed genetic structure emphasizes the need of protection of Hyacinth Macaws from different regions in order to maintain the genetic diversity of this species.

Student Thesis Level: Master’s Thesis in Business Administration Corporate Social Responsibility (CSR) networking : A case study on why members join CSR network and why are they sharing their knowledge

Purpose – This research focuses on finding the reasons, why members from different sectors join a cross-sector/multi-stakeholder CSR network and what motivates them to share (or not to share) their knowledge of CSR and their best practices. Design/methodology/approach – Semi-structured interviews were conducted with members of the largest cross-sector CSR network in Sweden. The sample base of 15 people was chosen to be able to represent a wider variety of members from each participating sectors. As well as the CEO of the intermediary organization was interviewed. The interviews were conducted via email and telephone. Findings – The findings include several reasons linked to the business case of CSR such as stakeholder pressure, competitive advantage, legitimacy and reputation as well as new reasons like the importance of CSR, and the access of further knowledge in the field. Further reasons are in line with members wanting to join a network, such as access to contact or having personal contacts. As to why members are sharing their CSR knowledge, the findings indicate to inspire others, to show CSR commitment, to be visible, it leads to business opportunity and the access of others knowledge, and because it was requested. Reasons for not sharing their knowledge would be the lack of opportunity, lack of time and the lack of experience to do so. Originality/value – The research contributes to existing studies, which focused on Corporate Social Responsibility and cross-sector networking as well as to inter-organizational knowledge sharing in the field of CSR.

The development of the nutrition and activity knowledge scale for use with people with an intellectual disability

Background Obesity is an increasing health problem for many Australians, no less so among people with an intellectual disability. Behaviour change aimed at improving nutritional intake and increasing levels of physical activity is a requirement for the reduction of obesity. An essential part of this process is to first ascertain the level of knowledge and beliefs people with an intellectual disability have about these behaviours.

Methods The aim of this study was to develop and psychometrically evaluate a scale to assess levels of nutritional and physical activity knowledge among people with an intellectual disability.

Results Seventy-three people with an intellectual disability completed the interview-rated scale at time 1 and 66 of them completed it again at a 3-week re-test.

Conclusions The scale demonstrated strong factorial construct validity, high internal consistency and good temporal stability. The applications of this scale in future research and in intervention programmes are discussed.

Effect of a self-directed learning package on emergency nurses` knowledge of assessment of oxygenation and use of supplemental oxygen

Abstract Emergency nurses frequently and independently make decisions regarding supplemental oxygen. The importance of these decisions for patients is highlighted by the well documented association between respiratory dysfunction and adverse events. This study aimed to: (i) examine the effect of educational preparation on emergency nurses' knowledge of assessment of oxygenation, and the use of supplemental oxygen; (ii) explore the impact of existing knowledge on decisions related to the implementation of supplemental oxygen; and (iii) explore nurses' characteristics that were associated with effectiveness of the educational preparation. A pretest/post-test, controlled, quasi-experimental design was used in this study. Educational preparation was effective in increasing emergency nurses' knowledge. Baseline level of knowledge was predictive of reports of independent decisions regarding the implementation of oxygen. There was a significant positive relationship between postgraduate qualification in emergency nursing and the effect of education, and significant negative relationships between effect of education and baseline level of knowledge and daily decisions to implement supplemental oxygen.

Development, reliability and validity of an instrument measuring the attitudes and knowledge of emergency department staff regarding the emergency nurse practitioner role

Introduction: The Emergency Department (ED) at The Northern Hospital is currently participating in the Victorian Department of Human Services funded Emergency Nurse Practitioner Project. This project aims to develop, implement and evaluate the Emergency Nurse Practitioner role in Victorian EDs. This led to a need to develop a specific data collection tool called The Northern Emergency Nurse Practitioner Staff Survey to examine the knowledge and attitudes of ED medical and nursing staff. This paper describes the development of The Northern Emergency Nurse Practitioner Staff Survey and presents the results of reliability and validity studies. Method: Twenty-five items were developed and piloted on a sample of 58 ED medical and nursing staff. Content and face validity were established by expert panel review. Reliability was established by tests of unidimensionality, exploratory factor analysis and internal consistency. Results: Four items were discarded because of low item to total correlation. Exploratory factor analysis of the remaining items revealed five factors with eigenvalues >1 and acceptable correlation coefficients that explained 76.7% of the variance. Cronbach’s coefficent α for these items was 0.926 indicating a high degree of internal consistency. The factors were titled to reflect the content domain of the items in each factor and the factors arranged in a logical sequence to form the final version of The Northern Emergency Nurse Practitioner Survey.

Knowledge management and its links with quality

Knowledge management is a concept that continues to draw a lot of interest. It is the process of sharing knowledge within an organisation to achieve better performance. It can be utilised by all organisations, many of which may not even be aware they are using the concept nor of its links with Quality management. By implementing an effective KM system increased organisational performance and ultimately a competitive advantage can be obtained - both of which correlate to the philosophy of Quality. This paper raises issues about the relationship between the gathering, storing and sharing of knowledge and the philosophy of continuous improvement with the facilitation of teamwork. It concludes by attempting to encourage further debate and research into the area by suggesting that Knowledge Management may be well the 'catalyst' for the resurgence of Quality Management.

Knowledge, risk perceptions and condom usage in male sex workers from three Australian cities

The study identifies factors associated with knowledge and perception of risk of HIV/AIDS, as well as attitudes to and usage of condoms by a sample of male sex workers (MSW). One hundred and eighty-five male sex workers completed a self-reported questionnaire, including knowledge about HIV transmission, attitudes to condom use and perceptions and personal susceptibility to HIV and sexually transmitted infection (STI) risk, and a two-week diary recording use of condom during commercial sex encounters. The findings reveal that condom use was found in 77.7% of the encounters with clients and the majority of the respondents perceived themselves to be at no risk for HIV because of sex work. Independent sex workers from Melbourne and workers who owned their place of residence used condoms in a significant lower proportion. Generally speaking, knowledge about the risks associated with AIDS was high, with respondents showing lower knowledge about the risks associated with unprotected receptive or active oral sex. Participants held a positive attitude to condom use; most considered the provisions of condoms to be their responsibility rather than clients; and they were more worried about contracting an STI than HIV. Those who scored higher on the knowledge scale had more positive attitudes to condom use and those who had a more positive attitude to condom use recorded a perceived lower risk of contracting STI but not HIV. The study discusses the relevance of these findings for public health risk reduction and sexual health education campaigns.

Brokering knowledge : managing knowledge in a network of government and non-government human service delivery agencies

This paper examines aspects of knowledge management that are particularly important in the network of human service delivery agencies in Victoria. This network is characterised by four features: it is a cluster of networked organisations; professionals and others may act as knowledge brokers within and between organisations in the network; rapid change in both knowledge and organisation accentuates the importance of innovative knowledge and emergent organisation over and above routine instrumental knowledge within stable organisation; and consequently there is an underlying concern with dialogical rather than instrumental knowledge and its management, and particularly how it constitutes and is constituted by organisation. The paper describes the analytical tools that we consider particularly important in examining this situation – in particular, the distinction between instrumental and dialogical knowledge, and the role of knowledge brokers (and professionals as knowledge brokers). It concludes by relating this analysis to broader issues in organisation studies, and suggests paths for further examination of these issues.

Conservation management and diets of Powerful Owls (Ninox strenua) in outer urban Melbourne, Australia

The Powerful Owl Ninox strenua is Australia’s largest owl, and is mainly found east of the Great Dividing Range on the mainland in tall-open forests. The species is considered rare, both nationally and in the State of Victoria; and threatened in the Greater Melbourne area. Recovery plans for the future conservation management of N. strenua are being prepared in 2 states.

Historically, Powerful Owls have been thought to require large homes ranges (about 1000 ha per pair) in suitable old-growth forest, which provides nest hollows for the owls and their arboreal marsupial prey. Recent research, however, has found N. strenua may be more numerous and breed more successfully in a wider range of habitats than previously believed. In particular, the birds have been found living in forests and woodlands within the greater metropolitan areas of cities. The most extreme case is where a nest tree has been found within 800m of urban settlement and 6km from the centre of Brisbane.

In this paper we report on the diet, habitat use, and conservation management by a number of breeding pairs of owls in outer urban Melbourne. Study sites range from a relatively undisturbed rainforest habitat 80km from central Melbourne, through dry sclerophyll, eucalyptus-dominated open forest with some disturbance to a site 8km from central Melbourne in highly disturbed urban parkland.

Diets of the families of owls were determined by analyzing remains in regurgitated pellets. The data confirm that arboreal marsupials constitute the major prey items, especially the Common Ringtail Possum Pseudocheirus peregrinus. There were differences in diets depending on the availability of prey species, which suggest a level of opportunism not previously suspected. Our study is also the first to confirm the owls capture adult Common Brushtail Possums Trichosurus vulpecula (15% of pellets containing the remains of this large opossum have bones of mature adults at 1 site) and thus take prey up to two and a half times their own weight. As well our data suggest Powerful Owls are not restricted to hollow-dwelling prey, as in some sites the marsupials rested during the day either in leafy nests called dreys (P. peregrinus) or in house roofs (T. vulpecula).

In the most heavily disturbed sites, breeding success has been reduced, and we have evidence that in one particular year the young were eaten by one of the parents. This followed construction of a bicycle track under the nest during the breeding season. Recommendations are made for the future conservation and habitat management of Powerful Owls in the Yarra Valley corridor.

Ecosystem conservation in multi-tenure reserve networks : the contribution of land outside of publicly protected areas

Multi-tenure reserve networks have been developed as a mechanism to improve cross tenure management and protection of biodiversity, but also as a means of accounting for biodiversity assets managed for conservation outside of protected areas on public land. We evaluated the contribution of multi-tenure reserve networks to enhancing the comprehensiveness and representativeness of ecosystems in publicly protected areas, using three Australian case studies. All networks contributed to enhancing comprehensiveness and representativeness, but this contribution varied between networks and between components of those networks. Significantly, components on private land and "other public land" in all three networks greatly enhanced the protection of some ecosystems at a subregional scale. The Grassy Box Woodlands Conservation Management Network, in particular made a substantial contribution to conservation, with most components protecting remnants of an endangered and under-represented ecosystem. Multi-reserve conservation networks not only act to protect threatened and under-reserved ecosystems, but they also provide a mechanism to account for this protection. Thus, multi-tenure reserve networks have the potential to provide increased knowledge and understanding to conservation planning decision making processes.

Towards a set of priorities for bird conservation and research in Australia : the perceptions of ornithologists

Australian delegates at the Australasian Ornithological Conference (2007) were surveyed by questionnaire to determine their perceived research and conservation priorities for Australian birds (n = 134). Respondents were honours or postgraduate students (37.4%), academics (26.2%), wildlife managers (6.5%), land managers (6.5%), environmental consultants (5.6%), independent wildlife researchers (5.6%) or had ‘other’ occupations not relevant to birds or their management (12.1%). Respondents rated their priorities on a predetermined set of issues, and were invited to add additional priorities. ‘Conservation of threatened species’ was considered the highest priority, followed by ‘Conservation of birds and biodiversity in general’, ‘Monitoring’, ‘Management’ and ‘Working with communities’. ‘Animal welfare/rights’ was regarded as comparatively less important. Eight of 11 conservation strategies were regarded as of high importance, these included habitat protection and rehabilitation, threat abatement, research, advocacy and education. This study documents the view of the ornithological community with respect to priority issues facing birds and could potentially feed into government and other policies aimed at conserving and understanding Australia’s birds.

Policy framework for a knowledge society : families and knowledge

My thesis examines the link between families, harm and knowledge in a society where knowledge is increasingly the central organising principle (Bohme 1997: 449-450; Stehr 1994: 6), and represents the capacity for action (Stehr 1994: 8). I observed as a consultant in the 1990s that practitioners in family work were able to articulate what works but often unable to articulate why and therefore unable easily to replicate what works. This time coincided with increasing commentary on complexities of living, capacity of families to cope, identification of the scale of family harm, and use of the term 'the knowledge society'. My aim is to identify why what works, works with families exhibiting harmful behaviours and families acquiring knowledge from learning everyday life skills so as to lead less harmful and more fulfilling lives. And by such explanations inform, replicate and scale up practice to benefit more families exhibiting harm. I conceptualise the outcome as a sequence of family, community and policy work in an ecological framework (Bronfenbrenner 1979) within a knowledge society. My method was a year-long action research project with a family support service in New South Wales. I engaged in reflective practice with workers, and a parallel literature review that supported additional reflective practice. I found growing complexity of life requires growing knowledge. I found a distinction between everyday and abstract life worlds, and with families principally acting in the everyday life world. It is a world from which some families and their members seek to escape, often by means of harmful behaviours of neglect, abuse and violence. I substantiated the link that the family support service of my study sees between relationships, behaviours and affects; and I linked this in turn with its therapeutic engagement of the whole family — adults and children, male and female, victims and perpetrators. This engagement involves a process of learning (Rogers 1967: 280) to acquire fulfilling behaviours. It is a process of adult and experiential learning of relationship skills, drawing on under-used reserves of families. Relationship skills form a basis of acquiring other life skills since most require relationships with others to perform life skills. Combining the sequence of family, community and policy work with workers engaging in reflective practice of their work creates capacity for community institutions to replicate and scale up what works and why. Understanding this sequence may assist community institutions to inform policymakers of benefits common to all policy interests of such replication and scaling up. I conceptualise a policy framework of families and knowledge in a knowledge society and two lower level frameworks of process and content of life skills. Implications of these for practice, policy, and theory include a greater distinction between everyday and abstract knowledge and skills; recognition of a sequential process of information, learning, and knowledge; and inclusiveness and fluidity in learning in diverse adult learning settings and in family support professions.

(Re)producing power-knowledge-desire : young women and discourses of identity

This study focuses on three young women in their final year of school using data gathered during a year-long process of individual conversational interviews, the contents of which were largely determined by their interests. Three themes arise from critical incidents during this year - the debutante ball, teenage pregnancy and dieting. These themes are used to focus wide ranging explorations of what it is to be a young woman at this particular time. The broader cultural production of discursive positions available to, and developed by, these young women as part of their identity formation is discussed. Methodological issues concerning power relationships between research participants are also the focus of critical attention. It is considered that young women's bodies and bodily practices are central to understanding the processes involved in their identity formation. It is in this context that the focus turns to bodies that matter. In contemporary Western cultures 'adolescent bodies' could be said to matter 'too much' in the sense that they are increasingly the focus for disciplinary practices in institutions such as schooling, the church, the family, health care, health promotion and the media. This disciplining is legitimised because adolescence is socially constructed as a 'becoming'. In this case it is a matter of 'becoming woman'; a sort of apprenticeship which allows for knowledgeable others to provide not only guidance and nurturance, but discipline. Using insights gained from feminist poststructuralist theory and cultural feminism this thesis argues that the discourses and practices generated within and across institutions, which are normalised by their institutional base, are gender differentiated. The focus is on young women's embodied subjectivity and how the discourses and practices they engage with and in work to construct an ideal feminine body-subject. The discursive production of a gendered identity has a considerable impact on young women's health and their health-related behaviours. This is explored specifically in the thesis in relation to sexuality and the cultural production of the 'ideal' female body. It is argued that health education and health promotion strategies which are designed to influence young women's health related behaviours, need to consider the forms of power, knowledge and desire produced through young women's active engagement with institutionalised discourses of identity if they are to have an ongoing impact

Nursing work and nursing knowledge : exploring the work of women's health nurses, patterns of power and praxis

The majority of women's health nurses in this study work in generalist community health centres. They have developed their praxis within the philosophy and policies of the broader women's health movement and primary health care principles in Australia. The fundamental assumption underlying this study is that women's health nurses possess a unique body of knowledge and clinical wisdom that has not been previously documented and explored. The epistemological base from which these nurses' operate offers important insights into the substantive issues that create and continually shape the practice world of nurses and their clients. Whether this represents a (re)construction of the dominant forms of health care service delivery for women is examined in this study. The study specifically aims at exploring the practice issues and experience of women's health service provision by women's health nurses in the context of the provision of cervical cancer screening services. In mapping this particular group of nurses practice, it sets out to examine the professional and theoretical issues in contemporary nursing and women's health care. In critically analysing the powerful discourses that shape and reshape nursing work, the study raises the concern that previous analyses of pursing work tend to universalise the structural and social subordination of nurses and nursing knowledge. This universalism is most often based on examples of midwifery and nursing work in hospital settings, and subsequently, because of these conceptualisations, all of nursing is too often deemed as a dependent occupation, with little agency, and is analysed as always in relation to medicine, to hospitals, to other knowledge forms. Denoting certain discourses as dominant proposes a relationship of power and knowledge and the thesis argues that all work relations and practices in health are structured by certain power/knowledge relations. This analysis reveals that there IX are many competing and complimentary power/knowledge relations that structure nursing, but that nursing, and in particular women's health nurses, also challenge the power/knowledge relations around them. Through examining theories of power and knowledge the analysis, argues that theoretical eclecticism is necessary to address the complex and varied nature of nursing work. In particular it identifies that postmodern and radical feminist theorising provide the most appropriate framework to further analyse and interpret the work of women's health nurses. Fundamental to the position argued in this thesis is a feminist perspective. This position creates important theoretical and methodological links throughout the whole study. Feminist methodology was employed to guide the design, the collection and the analysis. Intrinsic to this process was the use of the 'voices' of women's health nurses as the basis for theorising. The 'voices' of these nurses are highlighted in the chapters as italicised bold script. A constant companion along the way in examining women's health nurses' work, was the reflexivity with feminist research processes, the theoretical discussions and their 'voices'. Capturing and analysing descriptive accounts of nursing praxis is seen in this thesis as providing a way to theorise about nursing work. This methodology is able to demonstrate the knowledge forms embedded in clinical nursing praxis. Three conceptual threads emerge throughout the discussions: one focuses on nursing praxis as a distinct process, with its own distinct epistemological base rather than in relation to 'other' knowledge forms; another describes the medical restriction and opposition as experienced by this group of nurses, but also of their resistance to medical opposition. The third theme apparent from the interviews, and which was conceptualised as beyond resistance, was the description of the alternative discourses evident in nursing work, and this focused on notions of being a professional and on autonomous nursing praxis. This study concludes that rather than accepting the totalising discourses about nursing there are examples within nursing of resistance—both ideologically and X in practice—to these dominant discourses. Women's health nurses represent an important model of women's health service delivery, an analysis of which can contribute to critically reflecting on the 'paradigm of oppression' cited in nursing and about nursing more generally. Reflecting on women's health service delivery also has relevance in today's policy environment, where structural shifts in Commonwealth/State funding arrangements in community based care, may undermine women's health programs. In summary this study identifies three important propositions for nursing: • nursing praxis can reconstruct traditional models of health care; • nursing praxis is powerful and able to 'resist' dominant discourses; and • nursing praxis can be transformative. Joining feminist perspectives and alternative analyses of power provides a pluralistic and emancipatory politics for viewing, describing and analysing 'other' nursing work. At the micro sites of power and knowledge relations—in the everyday practice worlds of nurses, of negotiation and renegotiation, of work on the margins and at the centre—women's health nurses' praxis operates as a positive, productive and reconstructive force in health care.

Knowledge, identities and dilemmas of the self in physical education teacher education

The purpose of this study was to understand how becoming a physical education teacher is shaped by personally and socially constructed knowledge and is affected by the rules and resources of the structural systems in which physical education teacher education (PETE) takes place. The study was influenced by the traditions of Personal Construct Theory (Kelly 1955), the theoretical tenets of social constructionism (Gergen 1991), and Giddens’s work on structuration (1984) and self-identity (1991). Ten PETE students participated in the study over almost three years. They undertook repertory grid sessions periodically through their study, followed by ‘learning conversations’, in which the grid itself was discussed, reworked and collaboratively analysed. All conversations were audio taped and were fully transcribed. The data were analysed in three ways, all of which were used to construct a story of the study. First, the grids were analysed for patterns, consistencies across students and for consistencies within students. These grids provided the first level story that related to constructions of knowledge. These constructions were then content analysed using analysis categories developed from Gergen’s notion of the saturated self and Giddens’ ideas of identity in late modernity. These analyses represented what Giddens calls a double hermeneutic since to all intents and purposes, the story of the study was constructed from the participants’ constructions of what it is to be a physical education teacher. The data suggests that during the process of constructing professional knowledge the student experienced a series of dilemmas of professional self-identity. It seems that to become a PE teacher, the dilemmas must be worked through until a position of what Giddens calls ontologist security has been achieved. Some students in this study had not managed to reach such a point before they left university and entered the teaching profession. In spite of this, the methods of the study allowed the participants to begin to articulate their theories and visions of teaching physical education. The therapeutic qualities of Kelly’s theory encouraged a number of the students to ‘see it differently’ (Rossi, 1997) and to begin to develop a rationale for physical education based on educational practice that considers the needs of individuals and the promotion of a socially just community. I have argued however that this ‘critical’ approach to physical education pedagogy was considered risky and as such students who were prepared to engage in such risk strategies also had other strategic relational selves (Gergen, 1991) to minimise risk at key times during their teacher education.
