A terminal assessment of stages theory : introducing a dynamic states approach to entrepreneurship

Stages of Growth models were the most frequent theoretical approach to understanding entrepreneurial business growth from 1962 to 2006; they built on the growth imperative and developmental models of that time. An analysis of the universe of such models (N=104) published in the management literature shows no consensus on basic constructs of the approach, nor is there any empirical confirmations of stages theory. However, by changing two propositions of the stages models, a new dynamic states approach is derived. The dynamic states approach has far greater explanatory power than its precursor, and is compatible with leading edge research in entrepreneurship

Sickness absence and 'working through' illness: a comparison of two professional groups

BACKGROUND: Few studies have investigated occupational groups reporting low rates of sickness absence because of an assumption that these rates indicate low morbidity. This is inconsistent with the view that sickness absence, which may be caused by social and psychological rather than medical factors, does not equate with morbidity. This paper investigates rates of sickness absence and factors influencing decisions not to take sick leave among doctors and a comparative professional group. METHODS: A postal survey was sent to 670 general practitioners (GPs), 669 hospital doctors and 400 company 'fee earners'. Qualitative interviews were conducted with 64 doctors reporting an illness lasting one month or more in the last three years. RESULTS: Self-reported health status was similar for both groups but GPs reported higher levels of occupational stress. However, doctors were significantly less likely to report short periods of sick leave in the previous year. Over 80 per cent of all respondents had 'worked through' illness, citing cultural and organizational factors behind their decision not to take sick leave. Barriers to sick leave among doctors included the difficulty of arranging cover and attitudes to their own health. CONCLUSIONS: Considerable emphasis has been given to the role of social factors in contributing to rates of sickness absence. These may also contribute to the decision not to take sick leave, resulting in possible inappropriate non-use. Measures to encourage and enable doctors to take sick leave might improve the management of their own health

Trends in Belgian premature avoidable deaths over a 20 year period

STUDY OBJECTIVES—To analyse over a 20 year period the level and trends in the "EC avoidable death indicators".
DESIGN—The Years of Potential Life Lost (YPLL) method applied to curative and preventive avoidable mortality indicators in Belgium for four successive five year periods, countrywide as well as by district, separately for women and men. Ratios of YPLL rates (age standardised) describe changes between 1974-78 and 1990-94.
SETTING—Belgium for the periods 1974-78, 1980-84, 1985-89, 1990-94.
PARTICIPANTS—All avoidable death cases aged 1-64.
MAIN RESULTS—Ratio of YPLL rates indicated a more favourable development between 1974-78 and 1990-94 in the EC avoidable indicators than in all causes premature mortality. The EC avoidable mortality indicators have been assigned to two categories, curative indicators and preventive indicators. The best ratio of YPLL rates was found in curative indicators for men but the largest gains in YPLL rates over the periods come from the "preventive indicators" in men. For women, malignant neoplasm of the breast rose to the first ranked in 1985-1989 and 1990-1994, where it contributed to more years of YPLL loss than motor vehicle accidents, and malignant neoplasm of the trachea, bronchus and lung had risen to the fifth ranked since 1985-89. The order of the top causes for men did not change between 1974 and 1994, except for cirrhosis of liver, which rose from the fifth to the fourth rank. In the particular case of one "preventive indicator", malignant neoplasm of the trachea, bronchus and lung, the regional analysis of time trend between 1974-78 and 1990-94 showed more districts with a favourable development for both men and women in the Flemish region than in Wallonia.
CONCLUSION—The YPLL method combined with the avoidable mortality indicators enabled us to compare the changes of curative and preventive EC avoidable indicators between 1974-78 and 1990-94. In the case of malignant neoplasm of the trachea, bronchus and lung, which is of major concern to the health promotion policies, changes over the periods have widened a "north/south" health contrast.
