The purpose of this study was to develop a regression equation that, incorporating the potential energy of the load in the hands, was capable of improved predictions of spinal compression forces. A stepwise polynomial equation was developed from EMG profiles of 15 muscles, and its spinal joint loading predictions at L4/L5 were compared to current methods of calculating spinal compression. Absolute muscle activation was shown to increase with increased loading height, indicating that the central nervous system responds to changes in spinal stability. The inclusion of potential energy into the calculation of spinal disc compression at L4/L5 improved estimates of the compressive forces acting on the spine. This is the first model to incorporate potential energy into a predictive model for lumbar spine compression without the use of electromyography. It was concluded that potential energy plays a vital role in dictating the recruitment patterns of the trunk. 相似文献

The cost structure of Australian public housing authorities and its implications for the social administrative side of public housing operations is examined through a study of the South Australian Housing Trust. The importance of the pooled debt burden for lowering costs to well below private market levels is indicated. The sales policy is examined and it is argued that the sale of public housing into owner occupation is a major exacerbating factor in the high cost of rental rebating and in unbalancing the social mix among public housing tenants. The implications of the 1978 Commonwealth State Housing Agreement for the South Australian Housing Trust are briefly examined. 相似文献

As part of the celebration of the 40th anniversary of the Society for Risk Analysis and Risk Analysis: An International Journal, this essay reviews the 10 most important accomplishments of risk analysis from 1980 to 2010, outlines major accomplishments in three major categories from 2011 to 2019, discusses how editors circulate authors’ accomplishments, and proposes 10 major risk-related challenges for 2020–2030. Authors conclude that the next decade will severely test the field of risk analysis. 相似文献

This article draws upon case-study research into human resource development (HRD) within three small organizations in the north west of England. It positions the case-study work within an overall framework of doctoral research and summarizes the research design; discusses the characteristics and values of small organizations and how they influence HRD policies and practices: presents findings and conclusions about HRD in the case-study organizations, focusing in particular upon one case in the voluntary sector; compares and contrasts the different models of HRD in the three cases; and concludes with some suggestions for further research. 相似文献

Recent evidence has emerged that in Britain, like the US, many children below the official minimum school leaving age, are working. In many cases, the work is illegal. Research in the US suggests that many working children risk accidents and other hazards to health. Evidence from Britain on the health and safety aspects of child labour is of a more fragmentary nature, but enough exists to suggest a need for greater vigilance. 相似文献

Summary This article reports on the first extensive survey of ApprovedSocial Worker (ASW) activity under the Mental Health (NorthernIreland) Order 1986. The integrated health and social servicesorganizational structure, the adverse effects on individualmental health of the legacy of thirty years of civil conflictand the move from hospital to community care are significantfeatures which have influenced the delivery of mental healthsocial work services locally. The practice and experience ofASWs was surveyed by postal questionnaire and user and carerexperience of compulsory hospital admission was investigatedby a series of focus groups. The study revealed that two-thirdsof ASWs had experience of acting as an applicant in compulsoryhospital admission during the past two years. Nearly half (42per cent) of these ASWs had reported experience of between oneand five admissions and one-tenth had completed over twentyadmissions in the two-year period. In only a small minorityof cases did joint face-to-face assessment with the GeneralPractitioner (doctor) take place; nearly half of ASWs reporteddifficulties in obtaining transport; and only one-fifth of ASWshad experience of acting as a second approved social worker.Half of ASWs reported experience of guardianship, either asapplicant or in making the recommendation. Both service usersand carers reported a lack of understanding about the role ofthe ASW and complained about the lack of alternative resourcesthat ASWs could use to prevent hospital admissions. These findingsare discussed and a number of recommendations are proposed forimprovements to approved social worker practice. 相似文献
