Role consensus and job satisfaction in the educational organization : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Arts in Education at Massey University

A theory of social exchange was used as the framework for investigating role consensus between the Head Teacher and his staff on expectations of teacher and Head Teacher role and relating consensus to teacher job satisfaction. Association between job satisfaction and a number of personal variables was also hypothesised. The sample consisted of 147 intermediate school teachers in the ten intermediate schools in a New Zealand city. Only one of two central hypotheses proved significant. Role consensus between the Head Teacher and his staff on expectations of Head Teacher behaviour was positively related to job satisfaction, in that the greater the role consensus the greater the job satisfaction. No relationship was found between role consensus on expectations of teacher behaviour and job satisfaction. Only one of the personal variables, sex, proved to be related to job satisfaction, in that female teachers expressed greater job satisfaction than male teachers

Living alone as a lifestyle among older people in New Zealand

This paper discusses living alone as a lifestyle among older people in New Zealand, including population trends and living a meaningful life

An evaluation of mixed methods (diaries and focus groups) when working with older people

This paper considers the advantages and limitations of using mixed methods, diaries and focus groups in research with older people, specifically research investigating the interaction experiences of older individuals as customers, members and workers with public-, private- and community-based organisations. Drawing on the literature on mixed method integration, five distinct advantages were identified: development, completeness, expansion, offsetting and initiation. Two limitations were also noted: demands of the data collection on the participants and insufficient depth. Each is discussed in the context of the particular research project, with the suggestion that mixed methods be used in future research with older people

Internet/e-mail usage and well-being among 65-84 year olds in New Zealand: policy implications

Research indicates that significant groups of older people are using Internet/e-mail technology. Using data from a 2007 random sample of 1,680 New Zealanders aged 65-84, predictors of Internet/e-mail usage and the impact of usage on well-being were investigated. Gender, age, education, household composition, income, and work were significant predictors of Internet/e-mail usage. Significant positive relationships were also found between Internet/e-mail usage, self-rated health, leisure/recreation participation and leadership, and well-being. These research findings suggest that public policies should encourage older people to adopt Internet/e-mail technology to ensure continued participation, learning, and well-being throughout later years

Metabolic consequences of NDUFS4 gene deletion in immortalized mouse embryonic fibroblasts.

Item does not contain fulltextHuman mitochondrial complex I (CI) deficiency is associated with progressive neurological disorders. To better understand the CI pathomechanism, we here studied how deletion of the CI gene NDUFS4 affects cell metabolism. To this end we compared immortalized mouse embryonic fibroblasts (MEFs) derived from wildtype (wt) and whole-body NDUFS4 knockout (KO) mice. Mitochondria from KO cells lacked the NDUFS4 protein and mitoplasts displayed virtually no CI activity, moderately reduced CII, CIII and CIV activities and normal citrate synthase and CV (F(o)F(1)-ATPase) activity. Native electrophoresis of KO cell mitochondrial fractions revealed two distinct CI subcomplexes of ~830kDa (enzymatically inactive) and ~200kDa (active). The level of fully-assembled CII-CV was not affected by NDUFS4 gene deletion. KO cells exhibited a moderately reduced maximal and routine O(2) consumption, which was fully inhibited by acute application of the CI inhibitor rotenone. The aberrant CI assembly and reduced O(2) consumption in KO cells were fully normalized by NDUFS4 gene complementation. Cellular [NAD(+)]/[NADH] ratio, lactate production and mitochondrial tetramethyl rhodamine methyl ester (TMRM) accumulation were slightly increased in KO cells. In contrast, NDUFS4 gene deletion did not detectably alter [NADP(+)]/[NADPH] ratio, cellular glucose consumption, the protein levels of hexokinases (I and II) and phosphorylated pyruvate dehydrogenase (P-PDH), total cellular adenosine triphosphate (ATP) level, free cytosolic [ATP], cell growth rate, and reactive oxygen species (ROS) levels. We conclude that the NDUFS4 subunit is of key importance in CI stabilization and that, due to the metabolic properties of the immortalized MEFs, NDUFS4 gene deletion has only modest effects at the live cell level.
