Dosage-response analysis for a semi-quantal response derived from an aqueous biological assay

This paper is concerned with the interpretation of semi-quantal or graded responses in biological assay. On the basis of a model by which the various response categories represent contiguous intervals on an underlying quantitative scale reflecting time to death, a method of analysis for semi-quantal data is put forward. The results are illustrated by an aqueous assay designed to assess the toxicity of an effluent. It is confirmed that the proposed method of analysis leads to more precise estimates of the dosage-response relation than the alternative quantal response analysis of each response threshold.     

2 Old Assumptions,New Work

Abstract

We review the literature on nonstandard work with three aims: to portray the breadth and nature of the research and theorizing to date, to document the challenges and opportunities this domain poses to both practice and theory, and to bring the study of nonstandard work more to the center stage of micro-OB. After defining nonstandard work and documenting scholarly interest in it, we discuss the literature on the experience of nonstandard workers, on managing the nonstandard workforce, as well as that on managing the interface between standard and nonstandard workers. We analyze the themes that are raised in these literatures and point to new research questions that need to be addressed. Research on nonstandard work can enhance our understanding of the nature of work, the relationship between individuals and organizations, and how organizations and individuals can undertake these new work forms.     

Grant monitoring by charities: The process of grant-making and evaluation

This article presents the results of a survey of grant monitoring in 170 UK charities. The monitoring and evaluation process is modelled and the extent to which donors follow this is explored. Although over 70 per cent of donors monitored grants, a much smaller percentage proceeded to evaluate results. Reasons for this and an indication of how the processes are carried out are presented.

New perspectives on population: lessons from Cairo

The lessons from the 1994 World Population Conference in Cairo, Egypt, are summarized in this publication. The topics of discussion include the evolution of population policies, the changing policy environment, demographic trends, and solutions in the form of gender equity, provision of reproductive health services, and sustainable social and economic development. The program of action supported by 180 governments and targeted for 2015 articulated the goals of universal access to a full range of safe and reliable family planning methods and reproductive health services, a specified level of reduction in infant and child mortality, a specified level of reduction in maternal mortality, an increase in life expectancy to 70-75 years or more, and universal access to and completion of primary education. Other features include goals for improving women's status and equity in gender relations, expansion of educational and job opportunities for women and girls, and involvement of men in childrearing responsibilities and family planning. Steps should be taken to eliminate poverty and reduce or eliminate unsustainable patterns of production and consumption. Population policy must be integrated within social and economic development policies. About $22 billion will be needed for provision of family planning and reproductive health services by the year 2015. Costs will increase over the 10-year period due to the increased population to be served. Per person user costs for family planning alone are higher in countries without infrastructure and technical skills. Actual costs vary with the cost of contraceptive supplies, patterns of use, and efficiency of delivery systems. Although the plan offers 16 chapters worth of advice and recommends 243 specific actions, countries will have to be selective due to cost limitations. The 20/20 Initiative is proposed for sharing social service costs between international donors (20%) and host countries (20%). A separate UN projection of need is for 33% of support from international donors for family planning and related programs. The constraints to the implementation of the action plan are identified as the rate of demographic change, the extent of public support for population limitation and provision of family planning services, and potential conflicts of interests and funding between cooperating agencies. The World Bank has developed guidelines for policy development according to a country's identification as an emergent, transitional, or advanced country.     

Bridging the gaps: Intergenerational findings from the substance use disorder and recovery field

The substance use disorder and recovery field has undergone rapid transformation over the last 40 years. It currently has a workforce that includes three generations—Baby Boomers, Generation X, and Millennials. The current study sought to identify generational differences among those involved in the substance-use disorder and recovery profession using an embedded design and grounded theory approach. Findings suggest that generational differences do exist across the three generations in regard to ideologies, value of formal and informal knowledge, training, and education. Results from the current study provide a further understanding of how we may bridge perceived contentious ideologies and knowledge gaps between generations to better develop current and future professionals within the field.     

The Assessment of Industrial Health Hazards on The Basis of Observational Data — Some Statistical Pitfalls

Because of ethical and practical difficulties, controlled experimentation is seldom possible in the field of industrial medicine. Safety standards for industrial hazards must therefore be based upon uncontrolled observational data. This paper is concerned with the effects of population selection and of the association between exposure and response upon the exposure-response relationships derived from uncontrolled studies. It is shown that serious distortions may result and that ‘safe limits’ derived from uncontrolled studies may underestimate the real hazard.
