title: The effects of inhaled bergamot and geranium essential oils on rat behaviour

authors: Salvesen, Gregory John

subjects: Essential Oils

abstract: The aim of this study was to evaluate the behavioural effects of inhaled bergamot, geranium and a combination of these oils in three novelty evoked tests of anxiety. Sixty adult Hooded Rats (Rattus norvegicus), with 10 rats randomly assigned to one of the 6 test groups; three essential oil treated groups, and three control groups. The essential oil groups consisted of bergamot, geranium and a combined group, i.e. the combination of bergamot and geranium oil. The control groups consisted of the odour and vehicle control, with the anxiolytic drug diazepam as a positive control. The behaviour of rats was assessed on the elevate-plus maze, open-field and social interaction test. Diazepam increased open arm entries and the time spent in the open arms, decreased time spent in closed arms and increased the number of head-dips and unprotected stretch-attends in the EPM. In the open-field diazepam increased immobility time, decreased ambulation, increased grooming activity and reduced the amount of time spent exploring the arena. Similarly, diazepam decreased the frequency of separations, sniffs, follows, crawls, passive and active interactions with test partners in the social interaction test. Bergamot, geranium and the combination of the two oils increased total arm entries in the elevated-plus maze. Bergamot increased locomotion and exploratory behaviour in open-field and decreased contact latency and increased passive and active interaction between the rat pairs in the social interaction test. Geranium decrease immobility and increase the time spent rearing in the open-field and also increased active interaction, i.e. partner sniffing and decreased the amount of time the rat pairs spent apart in the social interaction test. The combination of bergamot and geranium oil increased locomotion and the time spent in Zone2, and also increased exploratory behaviour, i.e. the frequency and duration of rears in the open-field. In the social interaction test, contact latency was shortened and active and passive interactions between rat pairs were increased by the combination of essential oils. The present study established that bergamot, geranium, and the combination of the two oils had a stimulating effect in the elevated-plus maze and an anxiolytic effect in the open-field and social interaction tests when inhaled. Furthermore the study also demonstrated that the combining of the oils had a potentiating effect on the anxiolytic properties of the single oils.

title: Work-integrated learning gone full circle: How prior work placement experiences influenced workplace supervisors

authors: Martin, Andrew

subjects: work placements

abstract: This article reports of a study of workplace supervision and student experiences and outcomes through insights from semi-structured interviews with 21 graduates who had previously supervised work placement students. The study focused on questions framed from the perspective of the interviewees’ work placement experiences as a student and then as a supervisor (e.g., impact, motivation, insights for future students/supervisors, and graduate attributes). The findings from this study indicate importance of workplace supervisors setting expectations and engaging in initial planning and organizing for effective management of the work placement. Findings also suggest that the supervising can usefully take the form of mentoring, and that this provides the supervisor with professional development in self-management, effective communication and leadership. Implications for future WIL practice include utilizing workplace supervisors, particularly those who are themselves WIL graduates, to help further enhance student WIL experiences, learning outcomes, and legacies

title: Maori and psychology: Indigenous psychology in New Zealand

authors: Nikora, Linda Waimarie

subjects: Maori

abstract: Maori have their own approaches to health and well-being, which stem from a world view that values balance, continuity, unity and purpose. The world view is not typically thought of as 'psychology', yet it is a foundation for shared understandings and intelligible action among Maori. Maori behaviours, values, ways of doing things and understandings are often not visible nor valued. However, through these opening years of the twenty-first century, psychologists are slowly turning their attention to addressing this invisibility with the explicit agenda of building 'indigenous psychologies'
