On the Problem of Compromise Allocation in Multi-Response Stratified Sample Surveys

In stratified sample surveys, the problem of determining the optimum allocation is well known due to articles published in 1923 by Tschuprow and in 1934 by Neyman. The articles suggest the optimum sample sizes to be selected from each stratum for which sampling variance of the estimator is minimum for fixed total cost of the survey or the cost is minimum for a fixed precision of the estimator. If in a sample survey more than one characteristic is to be measured on each selected unit of the sample, that is, the survey is a multi-response survey, then the problem of determining the optimum sample sizes to various strata becomes more complex because of the non-availability of a single optimality criterion that suits all the characteristics. Many authors discussed compromise criterion that provides a compromise allocation, which is optimum for all characteristics, at least in some sense. Almost all of these authors worked out the compromise allocation by minimizing some function of the sampling variances of the estimators under a single cost constraint. A serious objection to this approach is that the variances are not unit free so that minimizing any function of variances may not be an appropriate objective to obtain a compromise allocation. This fact suggests the use of coefficient of variations instead of variances. In the present article, the problem of compromise allocation is formulated as a multi-objective non-linear programming problem. By linearizing the non-linear objective functions at their individual optima, the problem is approximated to an integer linear programming problem. Goal programming technique is then used to obtain a solution to the approximated problem.     

The Historical Development of Family Budget Standards in Britain,from the 17th Century to the Present

This article reviews the British tradition of research into household budget standards and describes a rich history of theoretical and methodological innovation in the social sciences. The origins of this enterprise lie in hypothetical family budget calculations made by political arithmeticians investigating living standards in the 1600s. Systematic budget inquiries emerge in England in the 1790s and by the end of the 19th century, normative standards are applied to determine lines of poverty across sections of British society. The first ‘scientific’ study to do this was conducted in England in 1912, local budget surveys flourish here until after the Second World War; by which time poverty researchers were abandoning them, turning instead to the data which was becoming available from national government surveys of family income and expenditure. Towards the close of the century, however, we see researchers trying to escape some of the circularity posed by family spending, which is, after all, constrained by household income. New and competing methods for determining household budget standards emerge before a groundbreaking inquiry attempts to establish a consensus in the field of minimum income standards research.     

A Review of Satisfaction Instruments Used in Long-Term Care Settings

Mandatory retirement for college and university faculty members will be abolished in 1994 in accordance with the amended Age Discrimination in Employment Act. The presidents of all institutions of higher learning with membership in Association of Gerontology in Higher Education, listed in the National Directory of Educational Programs in Gerontology, were asked to complete a survey that focused on the projected impact of this "uncapping."

Responses were received from 180 institutions (a 70% return rate). The typical respondent (85%-90%) anticipated that uncapping would have a negative impact on quality of instruction, scholarly contributions, and the institution's financial situation. Community relations and faculty morale were not expected to be as strongly impacted nevertheless, approximately two thirds of the respondents anticipated the effects would be negative here as well. Asked to descrlbe specific positive and negative outcomes in their own words, the presidents were more likely to cite negatives (75%) than positives (39%). Many of the responses given to the "positive" inquiry, however, were actually of a negative character, e.g., strategies for separating older faculty members from their positions despite the protection that will be granted when the amended Age Discriminatlon in Employment Act becomes effective. No respondent suggested the possibility of encouraging the continued or renewed development of their older faculty members, or of innovative plans for utilizing their abilities in different ways.     

Exposure,Resistance and Life Expectancy: Disease and Death During the Economic Development of Japan, 1900–1960

By 1900 Japan was still extremely poor, rural and predominantly agrarian: but it had achieved effective mortality parity with the more economically advanced and/or wealthier countries of Western Europe. As standards of living rose, life expectancy remained relatively stagnant until the end of World War II. Subsequently, in spite of the economy being still partially crippled by wartime destruction, life expectancy in Japan increased very rapidly. The analysis of these puzzling trends is undertaken by means of an historical model of mortality change in which life expectancy is interpreted as the function of both the relative overall resistance of the population to disease, and the degree to which it was protected from exposure to the leading causes of death. It is argued that the early and late Japanese achievement of relatively high life expectancy at relatively low levels of income rested on the government's efficient delivery of a very high level of protection from exposure to disease. The middle period, 1910 to 1940, represented a relative failure of protection due to the concentration of financial resources on the military sector; a failure which better diets etc. could not effectively counter. The post-war period involved a return to higher levels of investment in public health during a period of technological progress and structural shifts which enhanced the efficiency of such investment.     

Religiousness and Infidelity: Attendance,but not Faith and Prayer,Predict Marital Fidelity

High religiousness has been consistently linked with a decreased likelihood of past infidelity but has been solely defined by religious service attendance, a limited assessment of a complex facet of life. The current study developed nine religiousness subscales using items from the 1998 General Social Survey to more fully explore the association between religiousness and infidelity. Interestingly, logistic regressions using currently married participants (N= 1,439) demonstrated that attendance, but not faith, nearness to God, prayer, and other religious attributes, was related to infidelity. Exploratory analyses also found that individuals with high religious importance but low attendance were more likely to have had an affair and weak evidence that marital happiness moderated the association between religiousness and infidelity.     

On the planning and design of sample surveys

Surveys rely on structured questions used to map out reality, using sample observations from a population frame, into data that can be statistically analyzed. This paper focuses on the planning and design of surveys, making a distinction between individual surveys, household surveys and establishment surveys. Knowledge from cognitive science is used to provide guidelines on questionnaire design. Non-standard, but simple, statistical methods are described for analyzing survey results. The paper is based on experience gained by conducting over 150 customer satisfaction surveys in Europe, America and the Far East.     

Survival analysis based on the proportional hazards model and survey data

The authors propose methods based on the stratified Cox proportional hazards model that account for the fact that the data have been collected according to a complex survey design. The methods they propose are based on the theory of estimating equations in conjunction with empirical process theory. The authors also discuss issues concerning ignorable sampling design, and the use of weighted and unweighted procedures. They illustrate their methodology by an analysis of jobless spells in Statistics Canada's Survey of Labour and Income Dynamics. They discuss briefly problems concerning weighting, model checking, and missing or mismeasured data. They also identify areas for further research.     

The complexity of ignorance

We examine the kinds of mistakes that are frequently made when the general public is asked to identify political symbols from the past half century. A particularly striking phenomenon is inversion: the event is recalled backwards, so that Rosa Parks is remembered for having given up her seat on a bus to a white person. A second type of error occurs by linking a name to the wrong person, as when John Dean is identified as a movie actor (James Dean). Still another type of mistake involves a correct substantive categorization but with temporal displacement, for example, the Tet Offensive is said to have occurred during the Korean War. In each of these cases we are able to speculate about the social and psychological processes that have led to the misremembering. However, not every error is lodged in respondents: we initially treated as incorrect all answers that did not fit our own expectations; but we were soon forced to recognize that other frames of reference could be brought to the task and lay equal claim to the truth.
