Maori stories and symbols offer Westerns counselors a rich heritageof wisdom. This article provides a summary of key Maori mythologyand worldview highlighting the profound significance of sacredgeography—manifested in the marae (meeting ground) andthe wharenui (meeting house)—and family (whenau) imbedded in genealogy (whakapa). The authors then considerrelated significance for contemporary Maori, offer questions andapplications for western counsellors, and acknowledge essentialconsultation from a Maori staff advisor (te kaiurungi).  相似文献

Evidence of substantial growth in unionization among university noninstructional staff over the past 20 years (Hurd and Woodhead, 1987) and the emergence of a quality movement in higher education linking employee attitudes toward the work environment with increased productivity point to the need for additional research into union and nonunion staff perceptions of the work environment. This paper describes a conceptually oriented, exploratory study of the university work environment as perceived and defined by union and nonunion noninstructional staff.  相似文献

The archive is a cultural institution that creates a framework for the social and collective memory and as such is one of the collection of knowledge institutions that not only preserves and classifies “texts” but uses them to re-create collective memory and sometimes to invent cultural histories. Like all knowledge institutions, the archive is also a construction deeply implicated in knowledge politics or what Foucault calls power/knowledge. In the past the archive has functioned as a central metaphor for the construction of human knowledge in all it is different institutional forms and like the encyclopedia and the camera, the archive produces highly coded representations that make implicit validity claims to the truth and justice of the past. Politically speaking, those who control the archive control the past. In the digital world, the archive is used to describe a machine-readable location as a store for “data” and “information.” Digital technologies radically alter our existing institutions, making access to their embedded knowledge widely available and enable learning and research anytime, anywhere. Data analytics algorithmically can manipulate electorates and entire democracies in new ways, while destabilising the free press. This article asks what digitizing an archive means for collective memory, for the history of institutions and for politics in the Cloud.  相似文献

In this article, we map the extent of educational inequality within Tasmania, and between Tasmania and the rest of Australia, using National Assessment ProgramLiteracy and Numeracy (NAPLAN) and senior secondary attainment data. This analysis yields some surprising findings, showing the success of Tasmanian primary and high schools and that Tasmanian educational inequality is most strongly expressed at the senior secondary level. We conclude that using such publicly available data to identify differential achievement within and between jurisdictions would strengthen public policy and practitioner interventions aimed at achieving more equal educational outcomes for students in all schools. Our findings also have implications for research directions in this field, suggesting that by analysis of NAPLAN and My School data across individual schools and jurisdictions academic researchers could assist practitioners gain a deeper understanding of inequalities reproduced by the systems they are working within, while finding examples of schools and systems which show a greater level of success in ameliorating disadvantage.  相似文献

The monkey’s capacity to extract tonal pattern from a sequence of tones was assessed in four subjects that had the benefit of substantial past experience in discriminating, matching, and remembering acoustic stimuli. In Experiment 1, the monkeys failed to transfer their well-established matching behavior to the matching of two structured sequences of tones that differed primarily in tonal pattern, indicating that for them tonal pattern was not a salient feature of the acoustic stimuli. Experiment 2 was an attempt to encourage tonal pattern perception by employing, within a discrimination paradigm, very simple tonal patterns and multiple exemplars of the positive and negative patterns; the transfer design, borrowed from Hulse and Cynx (1985), was a powerful one for revealing tonal pattern perception. Verifying earlier results from our laboratory, there was little in the monkeys’ transfer performance to indicate that they had extracted tonal pattern from the acoustic stimuli. Major discriminative control seemed to be vested in the first tone of each exemplar. This apparent cognitive limitation may be rather general among animals, perhaps reflecting an intimate connection between the capacity for tonal pattern perception and that for acoustically based language.  相似文献

Severe underrepresentation of African-Americansamong postsecondary faculty is often linked toeducational pipeline supply problems,while institutional variations in demandfor black faculty labor and barriers to theirrecruitment and retention receive less empiricalattention. Using a nationally representative sample ofcollege faculty from a wide array of institutions andscience disciplines, this study investigates linksbetween internal organizational conditions and blackfaculty representation. Hypotheses derive from competingexplanations of the role of race in academicorganizations: institutionalized discrimination to protectdominant group privileges; statistical discriminationbased on expectations of racial group differences inacademic preparation; labor supply and politicalconstraints on black faculty recruitment. A multivariateanalysis examines organizational conditions that promoteor curb these dynamics and their relationship to blackappointments at different tenure levels. Results indicate that although the discipline-specificblack doctoral labor supply is a powerful constraint onthe representation of black faculty, selectiveorganizational contexts are substantial influences as well. Although we find little evidence thatinsulation from competition or segmented faculty labormarkets influence the racial composition of faculties,black faculty are more often found whereinstitutionalized discrimination may be checked by greaterformalization and black constituencies on campus.Consistent with statistical discrimination, blackfaculty are poorly represented at research-orientedinstitutions, even controlling for the scholarly reputationof doctoral credentials.  相似文献
