The effects of whole-body vibration on the cross-transfer of strength

This study investigated whether the use of superimposed whole-body vibration (WBV) during cross-education strength training would optimise strength transfer compared to conventional cross-education strength training. Twenty-one healthy, dominant right leg volunteers (21±3 years) were allocated to a strength training (ST, m = 3, f = 4), a strength training with WBV (ST + V, m = 3, f = 4), or a control group (no training, m = 3, f = 4). Training groups performed 9 sessions over 3 weeks, involving unilateral squats for the right leg, with or without WBV (35 Hz; 2.5mm amplitude). All groups underwent dynamic single leg maximum strength testing (1RM) and single and paired pulse transcranial magnetic stimulation (TMS) prior to and following training. Strength increased in the trained limb for the ST (41%; ES = 1.14) and ST + V (55%; ES = 1.03) groups, which resulted in a 35% (ES = 0.99) strength transfer to the untrained left leg for the ST group and a 52% (ES = 0.97) strength transfer to the untrained leg for the ST + V group, when compared to the control group. No differences in strength transfer between training groups were observed (P = 0.15). For the untrained leg, no differences in the peak height of recruitment curves or SICI were observed between ST and ST + V groups (P = 1.00). Strength training with WBV does not appear to modulate the cross-transfer of strength to a greater magnitude when compared to conventional cross-education strength training.

Policy implications of the transfer of ownership of Scotia Sanctuary for the National Reserve System in Australia

The recent purchase of Scotia Sanctuary, in western New South Wales, by the Australian Wildlife Conservancy (AWC), with significant funding from the Commonwealth government raises questions about the National Reserve System in Australia. The property had been placed on the market by the financially strapped Earth Sanctuaries Ltd (ESL). The Commonwealth's involvement represents an important landmark in private land conservation. This commentary investigates some of the possible policy implications this intervention may have for the National Reserve System as a whole and, in particular, about the role of private land within this System.

The transfer of management accounting practices from London counting houses to the British North American fur trade

During the late eighteenth and early nineteenth centuries management accounting practices were transferred from London counting houses to the British North American fur trade. This transfer involved a set of practices that was more effective for implementing the strategy being pursued at the time than the set used with the previous strategy. London counting houses had developed management accounting practices to facilitate their backward integration strategies with America and the West Indies. Pivotal to this development was the requirement for sub-unit accountability and responsibility.

Defining plant resistance against Phytophthora Cinnamomi and application of resistance to revegetation

Phytophthora cinnamomi is a soil borne plant pathogen that causes devastating disease in many Australian ecosystems and threatens the survival of native flora. Compared with the number of plant species that are susceptible to P. cinnamomi, only a few species are known to be resistant and control of this pathogen by chemicals is difficult and undesirable in natural systems. The major aim of our research is therefore to characterise natural resistance and determine which signalling pathways and defence responses are involved. Our examination of resistance is being approached at several levels, one of which is through the use of the model plant, Arabidopsis. Previously, Arabidopsis had been shown to display ecotypic variation in responses to P. cinnamomi and we are exploring this further in conjunction with the analysis of a bank of Arabidopsis defence pathway mutants for their responses to the pathogen. These experiments will provide a fundamental basis for further analysis of the defence responses of native plants. Native species (susceptible and resistant) are being assessed for their responses to P. cinnamomi at morphological, biochemical and molecular levels. This research also involves field-based studies of plants under challenge at various sites throughout Victoria, Australia. The focus of this field-based research is to assess the responses of individual species to P. cinnamomi in the natural environment with the goal of identifying individuals within susceptible species that display 'resistance'. Understanding how plants are able to resist this pathogen will enable strategies to be developed to enhance species survival and to restore structure and biodiversity to the ecosystems under threat.

The politics of resistance to workplace cultural diversity education for health service providers : an Australian study

This qualitative study has as its focus an exploration of health service providers' perceptions and experiences of the processes and implications of delivering workplace cultural diversity education for staff. Data were obtained from conducting in-depth individual and focus group interviews with a purposeful sample of 137 healthcare professionals, recruited from over 17 different organizational sites. Participants included cultural diversity educators, ethnic liaison officers, health service managers, nurses, health interpreters, allied health professionals, and community-based ethnic welfare organization personnel working in or with select metropolitan health services in Victoria, Australia. Analysis of the data revealed that workplace cultural diversity education in healthcare is a significant site of resistance and struggle. 'Resistance' was expressed in several forms including: the problematization of resources and staff availability to attend cultural diversity education forums; indifferent failure to recognize cultural imperatives in healthcare; deliberate refusal to recognize cultural imperatives in healthcare; selective recognition of cultural imperatives in healthcare ('facts sheets' only); and the angry rejection of cultural imperatives in healthcare. 'Struggle', in turn, largely involved cultural diversity educators having to constantly 'cajole and convince' (and even manipulate) staff to attend cultural diversity education forums and using a 'velvet glove and iron fist' approach to teaching staff who remained resolute in their resistance when participating in educational forums. An important implication of this study is that the politics of workplace cultural diversity education - and the 'politics of resistance' to such programs - need to be better recognized and understood if the status quo is to be successfully challenged and changed. The need for critical debate and further comparative research on the subject are also highlighted.

Beyond the analogon; the "transfer of the referent" : the relationship between the external world experienced through culturally generated perceptual models constructed in the human mind, and the transfer of these images, via visual language, onto referen

Within 20th. Century art, the concept of the ‘normative’ image, as an attribute of things, has been challenged. As a consequence, paintings must now picture the ‘real’ world in other ways, incorporating knowledge and meaning beyond the analogon. Such descriptive representations were revealed as paradigmatic, rather than incontrovertible fact. Dependent on pre-conceived notions of stereotypicality, these descriptive images relied on surface illumination. My thesis explores images of things in the world as culturally inspired and information based. I examine paintings and sculptures of other cultures, such as black African, and other historical periods such as the Medieval, which reveal metonymously the basis for variations in representations of the ‘real’ world. The new enhanced representations which Modern artists created in their work were denigrated as deviant from the absolute ‘normative’ or regarded as distortions for purely mannerist and stylistic reasons. Postmodern research has reassessed them as multiple or extended imagings in whose facture new knowledge and human responses can be incorporated. These new forms of representation can be regarded as theoretical constructs rather than stylised depictions of appearance. In this way referents are transferred through the mind onto objects and vistas in the real world to align with our developed view of the physical world and better our understanding of humanity’s symbiotic relationship with nature.

Cross-sector transfer of consolidated financial reporting - conceptual concerns

This article addresses a major concern about the use of particular accounting concepts, notably those of control and assets, for whole-of-government consolidated financial reporting. While whole-of-government consolidated financial reports may resemble the formats required by accounting standards and so provide a benchmark for comparative purposes, inherent weakness in the specification of underpinning concepts means that proper and full application of the consolidation methodology cannot be assumed. A study of the whole-of-government consolidated financial reports of the Commonwealth, state and territory governments of Australia revealed that significant assets, obligations and controlled entities have not been included.

Mechanisms of resistance to the cytotoxic effects of oxysterols in human leukemic cells

We have developed hematopoietic cells resistant to the cytotoxic effects of oxysterols. Oxysterol-resistant HL60 cells were generated by continuous exposure to three different oxysterols—25-hydroxycholesterol (25-OHC), 7-beta-hydroxycholesterol (7β-OHC) and 7-keto-cholesterol (7κ-C). We investigated the effects of 25-OHC, 7β-OHC, 7κ-C and the apoptotic agent staurosporine on these cells. The effect of the calcium channel blocker nifedipine on oxysterol cytotoxicity was also investigated. Differential display and real-time PCR were used to quantitate gene expression of oxysterol-sensitive and -resistant cells. Our results demonstrate that resistance to the cytotoxic effects of oxysterols is relatively specific to the type of oxysterol, and that the cytotoxicity of 25-OHC but not that of 7β-OHC and 7κ-C, appears to occur by a calcium dependent mechanism. Oxysterol-resistant cells demonstrated no significant difference in the expression of several genes previously implicated in oxysterol resistance, but expressed the bcl-2 gene at significantly lower levels than those observed in control cells. We identified three novel genes differentially expressed in resistant cells when compared to HL60 control cells. Taken together, the results of this study reveal potentially novel mechanisms of oxysterol cytotoxicity and resistance, and indicate that cytotoxicity of 25-OHC, 7β-OHC and 7κ-C occur by independent, yet overlapping mechanisms.

Breast cancer : the embodied transfer of uncertainty and risk

The thesis highlights how women reconstruct themselves after mammography, following a positive diagnosis of cancer, and post mastectomy. It juxtaposes women's experiences of breast cancer with doctors' perceptions of their role in treating patients, allowing an understanding of how risk and uncertainty are transferred between the private and public spheres.

Will these glasses help? Holocaust videotestimony and the transfer of intangible heritage

An analysis of Erica's videotestimony, presented at the Jewish Holocaust Museum and Research Centre in Melbourne, reveals how audio-visual history can act as a medium for the transfer of cultural heritage, despite claims that the trauma of the Holocaust has destroyed the possibility of any meaningful transmissíon. It is argued that the discussion of personal photographs from before and after the Holocaust forms a key component of the videotestimony and constitutes the primary mechanism for intergenerational transfer of Jewish communal heritage, Transfer is further facilitated by the interviewer whose questioning explicitly encourages Erica to reflect on issues of cultural continuity. Significantly, Erica's answers do not always conform to the interviewer's expectations about Jewish communal and religious identification and this can result in tension between the
two. Here too the photographs play an important role in resolving tension between Erica and the interviewer.

The effect of resistance training on functional capacity and quality of life in individuals with high and low number of metabolic risk factors

OBJECTIVE—There are limited data on the effects of resistance training on the capacity to perform activities of daily living (ADLs) and quality of life (QoL) for individuals with a high number of metabolic risk factors (HiMF). In this study, we examined the effect of resistance training on the capacity to perform ADLs and QoL in individuals with HiMF and compared any benefits with individuals with a low number of metabolic risk factors (LoMF).

RESEARCH DESIGN AND METHODS—Fifty-five untrained individuals, aged 50.8 ± 6.5 years, were randomized to four groups: HiMF training (HiMFT), HiMF control, LoMF training (LoMFT), and LoMF control. At baseline and after 10 weeks of resistance training, participants underwent anthropometric measurements and assessments of aerobic power (Vo2peak), muscle strength, capacity to perform ADLs, and a self-perceived QoL questionnaire. A repeated-measures ANOVA was used to examine the effect of training over time among groups.

RESULTS—Training increased lean body mass in both HiMFT (P = 0.03) and LoMFT (P = 0.03) groups. Total fat content and Vo2peak improved in the LoMFT group only. Muscle strength improved in both training groups (P < 0.01). Time to complete ADLs was reduced by 8.8% in the LoMFT group (P < 0.01) and 9.7% in the HiMF group (P < 0.01). Only the HiMFT group reported improvement in QoL.

CONCLUSIONS— Resistance training improved muscle strength and the capacity to perform ADLs in individuals with HiMF and LoMF. Resistance training improved QoL for the HiMF group, and this result was independent of changes in body fat content or aerobic power. Longer training regimens may be needed to improve QoL in individuals with LoMF.
