Descriptive methods for evaluation of state-based intervention programs

In this article, the authors discuss program evaluation of intervention studies when the outcome of interest is collected routinely at equally spaced intervals of time. They illustrate concepts using data from the American Stop Smoking Intervention Study, where the outcome is state per capita tobacco consumption. States differ widely in mean tobacco consumption, and these differences should be accounted for in the analysis. A large difference in the variance of the intervention effect may be obtained depending on whether the variation in the between-state effects are considered. The confidence limits obtained by ignoring between-state effects are too optimistic in many cases.     

The fall in household size and the rise of the primary individual in the United States

The long-term fall in household size in the United States is discussed within the framework of the aging of the population, continuing as the effects of fertility and mortality decline accumulate. Using distributions of households by size from U.S. census data 1790–1970 and a components of change analysis on primary individuals for 1950–1974, household changes are related to demographic change for the periods 1790–1900, 1900–1950, and 1950–1974. Fertility and mortality declines have unambiguous impact on household size until the increases in primary individuals begin. But these, too, have a theoretically interesting, if indirect relationship to population structure.     

Operational research techniques in Hong Kong

This paper presents the results of a survey of the use and organisational place of operational research techniques in different sectors of Hong Kong industry. The factors assisting the rapid growth of industry in the city-state are presented and the effect these have on the use of OR techniques is discussed. For a newly industralised country such as Hong Kong the conclusion of the authors is that OR techniques are best introduced and practised in a multi-discipline management services department rather than in a designated OR department.     

Families Under the Microscope: Repeated Sampling of Perceptions,Experiences, Biology,and Behavior

Families are not frozen dioramas; they are alive, active, and changing. Models of real‐life marital and family processes require many moving pieces. An intensive repeated measures approach reaches beyond static representations of the family toward more dynamic models that depict “life as it is lived.” The appearance of studies that use diaries and biological sampling in everyday life has burgeoned in the family research literature. These methods are part of a larger class of naturalistic methods that assess families in action and that includes direct video and audio recordings of families in their everyday environments. This article summarizes research that uses diaries, observations, and biological data collected over time in natural settings to study families. It provides an overview of the major research questions, designs, methods of data collection, and statistical models used in those literatures. Theoretical contributions and next steps in naturalistic research on families are discussed.     

The Future of Serials Cataloging,CONSER and the ISSN: Conversations from the Field

What does the future hold for the shape of serials to come and for cataloging these and other continuing resources? How should cataloging change to cope with still-unknown types of continuing resources? Will there still be a need for cataloging? For CONSER? For ISSN? How can libraries position themselves to partner with nonlibrary metadata creators in a future linked data environment? Four serials experts discuss these and other questions in a free-ranging conversation about the future of serials cataloging.
