Economic potential and entry into marriage and cohabitation

This article explores the relationship between economic potential and rates of entry into marriage and cohabitation. Using data from the 1990 census and the 1980-1992 High School and Beyond (Sophomore Cohort), we developed a method for explicitly estimating five time-varying measures of earnings potential. The analyses of union formation are based on an intergenerational panel study of parents and children, to which our measures of earnings potential were appended. The results indicate that all five measures of earnings potential strongly and positively influence the likelihood of marriage for men, but not for women. Earnings potential does not affect entry into cohabiting unions for either men or women.     

Gender and work orientations in conditions of job insecurity

This paper explores women's and men's work orientations in conditions of job insecurity, arguing that it is time to move beyond essentalist conceptions of work orientations and central life interests in order to understand the significance of paid work in people's lives. Data from a qualitative study are presented which show that the significance of paid work and the priority given to home and work are affected by experiences of job insecurity, changing domestic circumstances and stage in the life cycle and that this is the case for both women and men. Conversely, the significance of paid work can affect how job insecurity is experienced and its impact on individuals and their families. The assumption that men's work orientations are homogeneous and that work is their central life interest is not supported by the findings presented here and it is argued that the significance of work in men's and women's lives is more variable than has hitherto been recognized. To capture this variability it is time to move away from the acrimony of the debate over women's work orientations and notions of a central life interest which underpin it.     

The Gambling Self-Efficacy Questionnaire: An Initial Psychometric Evaluation

Instruments to assess individuals' self-efficacy for the control of addictive behaviors have been useful for monitoring behavior change, predicting maintenance of treatment gains, and identifying potential relapse situations. The Gambling Self-Efficacy Questionnaire (GSEQ) was developed to assess perceived self-efficacy to control gambling behavior. A demographically diverse sample of 309 adult gamblers completed an initial set of 42 items, of which 16 were selected to form the final version of the GSEQ. The GSEQ showed high internal consistency ( = .96) and good test-retest reliability (r = .86). A factor analysis provided some support for a unitary factor structure. As expected, GSEQ scores were negatively correlated with reports of problematic gambling behavior. Participants experiencing problems related to their gambling behavior scored significantly lower on the GSEQ than those who were not experiencing gambling problems. This psychometric examination of the GSEQ supported its potential utility for treatment planning and outcome evaluation with problem gamblers.     

Product planning—we're still getting it upside down

This paper questions why with all the traditional inventive genius of the British people, this country is failing to hold its own against foreign competition. While the reasons for this are many, the author suggests that the conventional approach to new product development is a major factor. Industry should put the demands of the consumer first rather than an abstract pursuit of technological development. He suggests that for industry in general the needs of consumers should take precedence over the ‘technology push’.     

Pitfalls in planning for multinational operations

This paper reviews the planning practices in multinational firms, focusing particularly on the relationship between subsidiaries and head offices during the planning process. It examines the planning problems experienced by multinationals using a simple paradigm to classify problems according to whether their origin was primarily with home office or with subsidiary; with the planning system itself or with the managers involved in running that system.     

Quantile plots for mean effects in the presence of variance effects for 2k-p designs

In robust parameter design, variance effects and mean effects in a factorial experiment are modelled simultaneously. If variance effects are present in a model, correlations are induced among the naive estimators of the mean effects. A simple normal quantile plot of the mean effects may be misleading because the mean effects are no longer iid under the null hypothesis that they are zero. Adjusted quantiles are computed for the case when one variance effect is significant and examples of 8-run and 16-run fractional factorial designs are examined in detail. We find that the usual normal quantiles are similar to adjusted quantiles for all but the largest and smallest ordered effects for which they are conservative. Graphically, the qualitative difference between the two sets of quantiles is negligible (even in the presence of large variance effects) and we conclude that normal probability plots are robust in the presence of variance effects.     

Estimating the Structure of Agricultural Investment: A Stochastic- Coefficients Approach

Two approaches, a flexibie-accelerator model and a stochastic-coefficients alternative, are used to estimate the structure of aggregate agricultural investment. Structural estimates of the adjustment rates for each model differ. The stochastic-coefficients model, however, performs better in out-of-sample forecasting.     

The True Cost-of-Living Index With Changing Preferences

This article investigates the theoretical and empirical properties of a true cost-of-living index under conditions of changing preferences. A family of true indexes is defined based on the notion of the current utility function. A particular index, based on the previous period's utility level, is then defined. Given this definition, a true cost-of-living index is computed based on a quadratic expenditure system estimated with quarterly data from 1960–1981. For empirical purposes, changes in preferences are represented by the linear habit formation hypothesis. This index is then compared with Paasche and Laspeyres indexes. The true cost-of-living index grows somewhat faster than either the Paasche or Laspeyres index. It also displays considerably more variability.     

Use of a conceptual model of societal drivers of ecological change in South Florida: Implications of an ecosystem management scenario

Human-dominated ecosystems such as in South Florida's Everglades region are greatly affected by societal actions and choices, and efforts to restore degraded ecosystems must take into account the societal drivers of ecosystem change. A conceptual model of societal-ecological interactions within the region illustrates connections between major societal drivers, such as water management and land use, and ecological stressors, such as loss of habitat and nutrient loading. Using the conceptual model as an initial guide for discussion, examination of a restoration scenario for the region shows that social and economic effects from activities proposed in a restoration scenario will likely affect most sectors of South Florida. Political effects from changing land and water management practices likely will be significant, as will the physical effects of changing water structures and management practices. Conceptual models such as this can aid in the initial stages of ecosystem restoration discussions and can assist in planning for subsequent social science evaluations of specific societal impacts of actual proposed governmental restoration alternatives. In crafting restoration scenarios, local, regional, and national decision makers can use conceptual models such as this to help broaden the early considerations of how possible future changes in societal drivers, including management choices, will change ecological stressors that affect ecosystem health.     

Globalisation, the nation‐state and global society

This article examines the notion that globalisation has resulted in the decline of the nation‐state. It argues that during most of its history globalisation was in fact associated with the rise of the nation‐state through the construction of overseas empires that extended and strengthened it. The development of global political organization has reinforced the nation‐state through the growth of international organizations based on the principle of national sovereignty. It is transnational flows, networks, and organizations that have challenged the authority of the nation‐state. These do not, however, float in a global limbo but are always rooted in and dependent upon some nation‐state or other. Transnational movements can embarrass nation‐states but have little real impact upon them and challenge them far less than did the nationally based labour movements that have been undermined by globalisation. Some see globalisation as leading to a global society transcending national units but this view overlooks the continued importance of national institutions and international relationships, and the emergence of strong regional organizations, in a society that is essentially multi‐level rather than global in character.
