Remarriage Among Divorced Persons in New Zealand

Trends in the remarriage of divorced persons in New Zealand since World War Two are examined with special attention to the period since 1968 during which the divorce rate has risen rapidly. While remarrying divorcees have formed increasing proportions of marriage cohorts since the late 1960s the remarriage rate, especially for females, has risen only because the divorced population has become more youthful. Comparison of the remarriage experience of synthetic divorce cohorts for 1961 and 1976 suggests that the likelihood of remarriage has fallen for both sexes where divorce occurs at ages below forty, but in particular for females divorced in their thirties.     

Calibration of FI‐ISK,an Invasiveness Screening Tool for Nonnative Freshwater Invertebrates

The Freshwater Invertebrate Invasiveness Scoring Kit (FI‐ISK) is proposed as a screening tool for identifying potentially invasive freshwater invertebrates. FI‐ISK was adapted from the Fish Invasiveness Scoring Kit (FISK) of Copp, Garthwaite, and Gozlan, which is an adapted form of the Weed Risk Assessment (WRA) of Pheloung, Williams, and Halloy. Initial assessments using FI‐ISK, which include confidence (certainty/uncertainty) rankings by the assessor to each response, were calibrated to determine the most appropriate score thresholds for classifying nonnative species into low‐, medium‐, and high‐risk categories, using both the original medium‐to‐high risk threshold scores for the WRA (i.e., ≥6) and for FISK (i.e., ≥19). Patterns of the assessor's confidence, when making the responses during the FI‐ISK assessments, were also examined. Using receiver operating characteristic (ROC) curves, FI‐ISK was shown to distinguish accurately (and with statistical confidence) between potentially invasive and noninvasive species of nonnative crayfish (Decapoda: Astacidae, Cambaridae, Parastacidae), with the statistically appropriate threshold score for high‐risk species scores being ≥16. FI‐ISK represents a useful and viable tool to aid decision‐ and policymakers in assessing and classifying freshwater invertebrates according to their potential invasiveness.     

EXPONENTIAL DISPERSION MODELS AND THE GAUSS-NEWTON ALGORITHM

It is known that the Fisher scoring iteration for generalized linear models has the same form as the Gauss-Newton algorithm for normal regression. This note shows that exponential dispersion models are the most general families to preserve this form for the scoring iteration. Therefore exponential dispersion models are the most general extension of generalized linear models for which the analogy with normal regression is preserved. The multinomial distribution is used as an example.     

Inequality at work: Race,sex and underemployment

New indicators of underemployment are presented for whites, blacks, Mexican Americans and Puerto Ricans by sex. The indicators are based on hours worked, education, skill utilization, and pay. Data from the 1980 Current Population Survey are supplemented with Dictionary of Occupational Titles information to construct the indicators. Whites consistently have the lowest underemployment, and comparison across groups reveals the different types of employment problems faced by minorities and women. These indicators of underemployment are compared with those from a different conceptual approach (the Labor Utilization Framework) using the same survey data. The advantages of the new indicators are discussed.

Human and organizational factors in offshore safety

The role of human and organizational factors in predicting accidents and incidents has become of major interest to the UK offshore oil and gas industry. Some of these factors had been measured in an earlier study focusing on the role of risk perception in determining accident involvement. The current study sought to extend the methodology by focusing on perceptions of organizational factors that could have an impact on safety. A self-report questionnaire was developed and distributed to 11 installations operating on the UK Continental Shelf. A total of 722 were returned (33% response rate) from a representative sample of the offshore workforce on these installations. The study investigated the underlying structure and content of offshore employees' attitudes to safety, feelings of safety and satisfaction with safety measures. Correlations and step-wise regression analysis were used to test the relationships between measures. The results suggest that 'unsafe' behaviour is the 'best' predictor of accidents/near misses as measured by self-report data and that unsafe behaviour is, in turn, driven by perceptions of pressure for production.     

Putting consumer behaviour in its place: the Behavioural Perspective Model research programme

Consumer research remains overwhelmingly cognitive in orientation, partly because its apparent underlying philosophical stance usually goes unremarked and unchallenged. In so far as scientific progress relies on the interaction of competing theories, consumer research is impoverished by too great a reliance on a single approach to theory. This paper proposes an alternative to the prevailing 'intentional stance' on which consumer research predominantly rests; the 'contextual stance' eschews the intentionality of the cognitive explanations of consumer choice, substituting for it an account of behaviour determined by its environmental consequences. As a prelude to the interactive debate that these competing stances will hopefully engender, the paper demonstrates that the contextual stance is a viable strategy for consumer research. The contextual strategy leads to an alternative model of consumer choice to those based on social cognitive psychology. It is argued that this model of consumer choice in behavioural perspective provides a thoroughgoing conceptual reinterpretation of consumer behaviour and marketing management as currently envisaged.     

Predicting Spouses’ Perceptions of Their Parenting Alliance

This study used marital‐ and individual‐level variables to predict spouses’ perceived parenting alliance. One hundred married couples completed measures of parenting alliance, marital consensus, marital power, and depression. Analyses revealed that marital consensus was a significant predictor of parenting alliance for both parents, and that depression also was a significant predictor for wives. Analyses using both spouses’ data indicated that wives’ perceptions of consensus and depression significantly predicted both spouses’ parenting alliance, suggesting that wives are the barometer of the marital relationship ( Floyd & Markman, 1983 ) and of the parenting relationship as well. Implications for research are discussed.
