Practice-Specific Risk Perceptions and Self-Reported Food Safety Practices

The relationship between risk perception and risk avoidance is typically analyzed using self-reported measures. However, in domains such as driving or food handling, the validity of responses about usual behavior is threatened because people think about the situations in which they are self-aware, such as when they encounter a hazard. Indeed, researchers have often noted a divergence between what people say about their behavior and how they actually behave. Thus, in order to draw conclusions about risk perceptions and risk avoidance from survey data, it is important to identify particular cognitive elements, such as those measured by questions about risk and safety knowledge, risk perceptions, or information search behavior, which may be effective antecedents of self-reported safety behavior. It is also important to identify and correct for potential sources of bias that may exist in the data. The authors analyze the Food and Drug Administration's 1998 Food Safety Survey to determine whether there are consistent cognitive antecedents for three types of safe food practices: preparation, eating, and cooling of foods. An assessment of measurement biases shows that endogeneity of food choices affects reports of food preparation. In addition, response bias affects reports of cooling practices as evidenced by its relation to knowledge and information search, a pattern of cognitive effects unique to cooling practices. After correcting for these biases, results show that practice-specific risk perceptions are the primary cognitive antecedents of safe food behavior, which has implications for the design of effective education messages about food safety.     

Unmet Needs for Assistance with ADLs and IADLs: A Measure of Healthy Life Expectancy

Measures of healthy life expectancy have beendeveloped over the last thirty years to evaluate thequality of life of an increasing life expectancy.These measures are usually accounting for prevalencerates of either disability or physical dependence inperforming everyday activities. Although they allowfor a better assessment of quality of life, they arenot reflecting the fact that a disabled person mightbe receiving adequate or inadequate assistance forthese activities. In a context of population aging,where our health care system will have to deal moreand more with chronic disease instead of acutedisease, it is imperative to develop a measure thatwill account for the adequacy of the assistanceprovided to the disabled elderly population. Usingdata from the 1986 Health and Activity LimitationSurvey, we are introducing a measure of healthy lifeexpectancy which will fill this gap. We present theconstruction of this measure of population health anddiscuss its usefulness in assessing policies at amacro level.     

Appropriation et régulation des innovations biotechnologiques : pour une comparaison transatlantique

This article analyzes two biotechnological innovations — the tests of tracking the genetic risks of diseases and the transgenic organisms — and explores the controversies concerning the status of these new knowledges and the ways there are applied. It shows how these innovations were received in a different way in the United States and in France. The market regulation, which is strong in the USA is problematic in France. It is marginalized by the professional regulation in the case of the genetic tests. And in the other case it is limited by the control of the state, which constitutes some resources for the mobilization of the civil society against transgenic organisms. Finally the comparison consolidates the hypothesis of the emergence of a new regime of production of the knowledge, specified by the tension between a “market” regulation and a “consumerist-civic” regulation.     

On the historical origins of Chinese underdevelopment

Conclusion The Imperial regime bequeathed to its successors a double heritage and a double handicap: on the one hand, an exceptionally strong population pressure on the area of cultivated land; and on the other, a radical break between interior China (rural bureaucratic, traditional) and coastal China (cosmopolitan, enterprising, open to innovation). The history of the twentieth century only accentuated these contradictions and worsened these handicaps. Rooted in its urban bases, the Guomindang regime of 1927–1949 did virually nothing to transfer technology to the countryside, so that the gap between the two Chinas - coastal and interior - widened, and the regime was condemned to be swept away by peasant revolution. As for the People's Republic, by postponing the adoption of a real birth-control program until 1973, it wiped out a large part of the benefits that a policy of modernization extended for the first time ever to the whole country would have brought, and made economic take-off even more difficult in 1981 than it was in 1949.

Child welfare workers use of knowledge in their daily work

The debate continues on what constitutes core knowledge in professional work in child welfare and child protection. The aims of this article are to examine what different sources of knowledge social workers report to use in their daily work and to determine the importance of different knowledge sources in relation to their work experience, educational background and type of employment (caseworker/manager). Data were obtained from a survey completed by 390 social workers in municipal child welfare services in Western Norway. Social workers answered questions regarding their use of different knowledge sources in their daily work. The information they obtained in a particular case and their personal experiences were the most frequently used sources. Factor analysis revealed four subgroups of knowledge sources: The most frequently used were: (a) Colleagues and Supervision and (b) Personal Experience, followed by (c) Social Work Education, Courses and Municipal and State Documents, with (d) Journal Articles, Textbooks and External Sources being the least frequently used. The most important source for social workers with less work experience was Colleagues and Supervision, whereas the factor Journal Articles, Textbooks and External Sources was more often important for social workers with a master’s degree than for those without this level of education. Overall, social workers seem to rely mostly on personal experience and their colleagues as sources of knowledge in their work.     

Family 'Decline' and the Subjective Well-being of Adolescents

The goal of the present study was to determine to what extent an adolescent's subjective well-being is affected when changes in family structure reach a breaking point and the child can no longer stay with his family, but must be institutionalized. The participants were one hundred male and female adolescents, 12 to 19 years of age, 50 of which lived in children's homes, but were originally from 50 different families, and 50 of which lived at home with their parents. Two questionnaires were administered: (a) the French adaptation of the Life Satisfaction Scale (Blais et al., 1989) and (b) a questionnaire containing statements related to level of satisfaction in several areas, notably family relationships, body image, work and schooling, and leisure acitivites. The difference between the two groups was considerable, with more than one point separating the mean levels of satisfaction of the two groups (20% of the total length of the scale employed). A structural analysis of the results showed the direct or indirect influence of three factors related to placement in a children's home on life satisfaction: a direct effect of placement in a children's home, an indirect effect passing through the satisfaction with family life, and an indirect effect passing through the personal growth.     

A qualitative information system for data management

This article traces the path which led to the adaptation of the Information System approach to data management and the use of a Relational Data Base Management System in the Vitrine 2001 project, a research project looking at children's learning activities with computers using qualitative research techniques. The principles which guided the selection and design of the data base, consideration of its advantages, as well as guidelines to help others who may wish to use a similar instrument are also presented.     

The Instruction set of Questionnaires can Affect the Structure of the Data: Application to Self-Rated State Anxiety

The present study tested the assumption that self-ratings, such as those used for measuring state anxiety, do not measure a one-dimensional transcendent entity but involve decisions based on a multi-dimensional judgment. Two groups of subjects were presented with a balanced nine-item state anxiety questionnaire. Each group received a different set of instructions (a standard set and an altered instruction set suggesting unidimensionality of the questions in the questionnaire). It was hypothesized that this change in instructions would impact the structure of the data. The impact of the instructions was detectable at the level of the observed correlation between the negative and positive composites, Cohen's (1988) q=–0.27$. A multigroup confirmatory factor analysis showed that positive and negative wording factors correlated more strongly when unidimensionality was suggested than when standard instructions were used, q=–0.54. Theoretical and practical implications are discussed.     

Understanding My Culture Means Understanding Myself: The Function of Cultural Identity Clarity for Personal Identity Clarity and Personal Psychological Well‐Being

Culture is acknowledged to be a critical element in the construction of an individual's identity; however, in today's increasingly multicultural environments, the influence of culture is no longer straightforward. It is now important to explore cultural identity clarity—the extent to which beliefs about identity that arise from one's cultural group membership(s) are clearly and confidently understood. We describe a novel theoretical model to explain why having a clear and confident understanding of one's cultural identity is important for psychological well‐being, as it clarifies one's understanding of personal identity. We propose that a clear cultural identity clarifies one's personal existence, by providing a clear normative template, reducing personal uncertainty, providing an individual with a sense of continuity, and buffering an individual against the fear of death. We discuss the implications of this model within our complex cultural worlds.
