Learning from the law to address uncertainty in the precautionary principle

Environmentalists have advocated the Precautionary Principle (PP) to help guide public and private decisions about the environment. By contrast, industry and its spokesmen have opposed this. There is not one principle, but many that have been recommended for this purpose. Despite the attractiveness of a core idea in all versions of the principle—that decision-makers should take some precautionary steps to ensure that threats of serious and irreversible damage to the environment and public health do not materialize into harm—even one of the most widely endorsed principles needs considerable specification and refinement before it can be used. Moreover, the PP is an approach or guide to utilizing scientific evidence in social or legal decision-making contexts. In this it does not differ in kind from other approaches to using factual information such as in the law. The law provides some models for different strategies to guide decision-making under uncertainty when factual issues cannot be resolved with certainty. These in turn can help guide the formulation of different versions of PP and help clarify some presuppositions of the principle. Once some plausible versions of PP are articulated, I suggest some applications to existing environmental problems.     

The psychological sense of economic hardship: measurement models, validity, and cross-ethnic equivalence for urban families

Poverty is a community stressor that disproportionally affects ethnic minority families. One aspect of programmatic research on poverty focuses on the psychological sense of economic hardship. In a study of 319 African American, European American, and Mexican American urban families, parents completed objective measures of economic status and scales of perceived economic hardship that were adapted from previous research. Measurement models identified a coherent construct of psychological sense of economic hardship that was essentially equivalent for mothers and fathers, English- and Spanish-speaking Mexican Americans, and the 3 ethnic groups. In support of the validity of this construct, relations between objective indicators of economic status and perceived economic hardship showed equivalence across these same groups.     

The Tromsø Social Intelligence Scale, a self-report measure of social intelligence

Social intelligence is a construct that not only appeals to laymen as a relevant individual difference but also has shown promising practical applications. Nevertheless, the use of social intelligence in research and applied settings has been limited by definitional problems, difficulties in empirically differentiating social intelligence from related constructs, and the complexity of most existing measures of social intelligence. The goal of the present research was to address some of these obstacles by designing a multi‐faceted social intelligence measure that is short and easy to administer. Three studies were conducted to develop and validate the Tromsø Social Intelligence Scale (TSIS). Study 1 examined professional psychologists’ interpretations of social intelligence to derive a consensually agreed‐upon definition of the construct. In Study 2, a large pool of social intelligence items were tested, and a 3‐factor, 21‐item scale was identified. In Study 3, the stability of this measure was confirmed.     

Revisiting Group Attachment: Ethnic and National Identity

The study of ethnic and national identity, owing to the complex interaction between individuals, groups, and systems, has not remained confined to traditional disciplinary boundaries. In particular, a branch of social-psychological research has provided insight into the most fundamental aspect of this phenomenon, subjective bonds between individuals and groups. Here, data derived from a Q-methodological study of Basque national identity are used to show that claims advanced within the existing literature appear to be restricted in their ability to explain subjective attachment to the nation; that is, they cannot adequately account for the types of bonds that emerged from the Basque case study. Primarily through Q methodology, an alternative explanation and method for uncovering the ties between individuals and groups is offered. In the place of previously vague and restrictive a priori categories of collective attachment, Q is shown to offer a means by which to explore the subjective nature of ethnic and national identification.     

A Neuropsychological Approach to Intelligence

This paper proposes that current psychometric intelligence tests are limited in evaluating cognitive activity. From a neuropsychological perspective, they fail to measure some fundamental cognitive abilities such as executive functions, memory, and visuospatial abilities. The analysis of the Wechsler Intelligence Scale presented shows that the original rationale for selecting the specific subtests included in the WAIS was unclear. The concept of a g factor in cognition is also analyzed, with the conclusion that the g factor continues to be controversial. The value of intelligence tests in predicting school performance is also criticized. It is proposed that the psychometric concept of general intelligence should be deleted from cognitive and neurological sciences. Finally, it is proposed that, in the future, neuropsychological instruments sensitive to more specific cognitive abilities replace current psychometric intelligence tests.     

The Development of Person–Vocation Fit: A Longitudinal Study Among Young Employees

This two-phase panel study examines the development of the congruence between vocational interests and perceived skill requirements. Participants were 492 Dutch men and women between 18 and 26 years old, with a paid job in both phases. Three hypotheses inspired by the theory of work adjustment (Dawis and Lofquist 1984) and congruence theory (Holland 1992) were tested, using a composite index of fit proposed by Cronbach and Gleser (1953). The first hypothesis proposing that participants experiencing incongruence between their vocational interests and their perceived skill requirements are dissatisfied with their job was supported. The hypothesis that incongruence has a positive relationship with job change and a negative relationship with tenure was not confirmed. The expectation that the congruence between vocational interests and perceived skill requirements increases over time was confirmed. Furthermore, exploring determinants of change in vocational interests and perceived skill requirements, it was found that change in these domains was predicted by different variables, educational level being the only common factor. It is concluded that this study supports the longitudinal propositions of prevailing work-related person-environment fit theories.

The Feeling-Tone Questionnaire: Reliability and Validity of a Direct Patient Assessment Screening Instrument for the Detection of Depressive Symptoms in Cases of Dementia

The purpose of this study was to develop a reliable and valid measure of affective disorder in elderly demented patients. The field lacks instruments which are sensitive to detecting depressive signs in severely as well as mildly and moderately demented subjects. Two samples of subjects were chosen for study. The first sample consisted of subjects from six institutions, which were chosen for study from a probability sample of 25 long-term care institutions in New York City. This sample was part of the Cross-National Institutional Study conducted in New York and London (Gurland et al., 1979; Mann et al., 1984). Thirty patients were selected at random within each institution. The second sample consisted of 52 inpatients at Willard Psychiatric Center, a traditional state psychiatric hospital in upstate New York. All subjects had a chart diagnosis of dementia and were 60 years old or older. The mean age of the sample was 82 years and 56% of the subjects were female. The Feeling-Tone Questionnaire, which was developed for these analyses, consists of 16 dichotomous items and 16 5-point Likert ratings of affect. The reliability of this scale using Cronbach's alpha is .91 for the long-term care institutional sample and .90 for the psychiatric hospital sample. Interrater reliability for two raters on ten cases is .99. Test–retest reliability on ten cases with a 1-day to 2-day interval between trials is .81. A short mood scale was developed from the observational data as a validity measure for the Feeling-Tone Questionnaire. Evidence for the validity of the Feeling-Tone Questionnaire is provided.     

The development and predictive relations of play and language across the second year.

The play and language development of 171 toddlers was examined at 14 and 18 months by observing their activities on the Symbolic Play Test and by assessing their language skills using the MacArthur Communicative Development Inventories (MCDI) and the Reynell Developmental Language Scales. Additionally, data from the Bayley Scales of Infant Development and the MCDI were obtained at 24 months, in order to investigate how play and language measures taken at 14 and 18 months predict children's development at the age of 2 years. The results showed that the vocabulary production and symbolic play of the 14-month-old toddlers made a unique contribution to their language and cognitive skills at the age of 2 years, while at 18 months only language variables made a similar contribution. Other-directed pretense discriminated between the children's subsequent language and cognitive skills best, whereas nonsymbolic play had no independent predictive contribution. Significant gender differences were found in the use of nonsymbolic and symbolic play acts already at 14 months. Gender did not, however, contribute to the prediction of the children's subsequent skills, whereas maternal education significantly added to the prediction of the 2-year-olds' maximum sentence length and that of their cognitive development.
