Communicating risk to parents and those living in areas with a disaster history

This study explored how publics respond to risk communication in high probability but time-indeterminate natural disaster situations when parts of the area have been involved in a similar disaster before. An impending rockslide is expected to produce a tsunami in the fjord around Åknes in Norway. Waves may run up above sea level as high as 82 m or 269 ft. All residents (18 and older) of the four most threatened communities received a questionnaire to determine what they perceived to be useful risk information. Three hundred and eighty-two (43.6% of 875) responded. Results indicated that parents of children living within the tsunami risk zones perceived the risk information to be the most useful. Those who lived in communities that experienced a similar disaster in 1934 reported public meetings less useful than written or mediated information. Publics who lived in communities with such disaster history and those who were not parents posed special challenges in risk communication because they perceived information from the government agencies as lacking in usefulness. Therefore, committing the resources necessary to foster dialogues with a diversity of publics exposed to risk would be well served to fully understand the nature of risk communication responses, and to be able to save human lives.     

Building a statistical model to predict reactor temperatures

This paper describes the various stages in building a statistical model to predict temperatures in the core of a reactor, and compares the benefits of this model with those of a physical model. We give a brief background to this study and the applications of the model to rapid online monitoring and safe operation of the reactor. We describe the methods, of correlation and two dimensional spectral analysis, which we use to identify the effects that are incorporated in a spatial regression model for the measured temperatures. These effects are related to the age of the reactor fuel and the spatial geometry of the reactor. A remaining component of the temperature variation is a slowly varying temperature surface modelled by smooth functions with constrained coefficients. We assess the accuracy of the model for interpolating temperatures throughout the reactor, when measurements are available only at a reduced set of spatial locations, as is the case in most reactors. Further possible improvements to the model are discussed.     

WHITE ENROLLMENT IN NONPUBLIC SCHOOLS, PUBLIC SCHOOL RACIAL COMPOSITION, AND STUDENT PERFORMANCE

This research note presents preliminary research into the relationship between the racial composition of public schools in school districts and the percentages of white students in nonpublic schools in those districts. Specifically, we ask two questions: Is the enrollment of whites in non‐public schools associated with minority predominance in public schools? Is there an association between the enrollment of whites outside of the public school system and the academic performance of students in the public school system? Using two‐ and three‐level hierarchical linear models, we find that school districts that have more whites in nonpublic schools tend to contain public schools with larger percentages of minority students. Further, at both the school and individual levels, achievement test scores tend to be lower in districts in which white students tend to be enrolled outside of the public school system. In addition, the achievement gap between white and minority students tends to be greater in districts with relatively more students in nonpublic schools. These findings are consistent with the argument that the withdrawal of white students from the public school system is negatively related to academic achievement because it tends to concentrate minority students in public schools.     

HOW MANAGEMENT USERS VIEW INFORMATION SYSTEMS

The literature of management information systems suggests that substantial discord exists between management users and systems personnel. This paper describes the current attitudes of managers toward information systems and computers as reflected in seventy-five carefully structured interviews with managers from ten major companies. The author concludes that management user attitudes are quite favorable and do not reflect the predicted discord. In fact, the author believes that one of the major systems implementation problems of the future may be apathy rather than antipathy. The data collection was structured to indicate differences in attitudes on the part of users based on organizational level, functional area of work, type of activity, and type of environment.     

The Nature of Social Pasts and Their Use as Foundations for Situated Action

In this paper social pasts are considered to be foundations of everyday interpersonal life, including everyday situated action. We distinguish social pasts from culture by noting that the former involves recognition of specific joint acts and social placements while the latter involves recognition of ties to acts and placements in general. We further distinguish shared pasts–which refer to specific and previous joint acts or social placements that interactors constructed together–from common pasts–which refer to specific and previous joint acts or social placements that interactors constructed with others. We assess the importance of using either common or shared pasts in the course of completing and simplifying complex and everyday transactions so as to create an appearance of routine-ness in relation to constructing these acts.     

The right to be different: Multiculturalism and the racialization of scandinavian welfare politics; The case of Denmark

‘Multiculturalism’ as an influential ideology for structuring ethnic relations has become exposed to increasing critique also in the Scandinavian context. The paper discusses a racialized political debate, legislation, and institutional practices, taking Denmark as the prime example. An increasingly ‘dual welfare’ is becoming legitimized through a hegemonic culturalized language, consistently interpreting ‘the right to be different’ as ‘being different’, and ‘being different’ as being ‘non‐integrated’. In a society where public debate on ethnic and racial discrimination is less than rudimentary, tolerant claims of multiculturalist relativism are effectively turned upside down in the service of neo‐racism, the preachings of which are imperceptibly becoming adopted as the conventional wisdom. This calls for a discussion on ‘politics of recognition’ which brings the debate on the universalism and particularity out of the abstract, while focusing on the vicissitudes of contemporary democracy in a changing welfare state.     

Business Interest Group Power and Temporary Assistance to Needy Families*

Objectives. Our aim is to test the influence of business interest groups on Temporary Assistance to Needy Families (TANF) policy at the state level. Methods. We use the state TANF guarantee, the length of time recipients have before they lose their benefits, and the existence of a “family cap” as dependent variables in three models. Each of the models tests business interest group power and several other measures that represent possible influences on the dependent variable. Results. We find that business interest group power is significantly related to both the generosity of the TANF guarantee and to TANF time limits. However, it is not related to the presence of the family cap in state TANF policy. Conclusions. The evidence we found is consistent with the idea that those state TANF policies that are most intimately related to business interests are just those policies that are most affected by business group influence. States' TANF policies regarding maximum benefit and time limits both have a direct impact on wealth redistribution and labor‐market behavior. On the other hand, business interest groups do not seem to have much influence on the presence of TANF family caps, policies that are arguably less the concern of business interest groups, and more connected to public attitudes toward families and children.     

POPAN-4: enhancements to a system for the analysis of mark-recapture data from open populations

We describe recent developments in the POPAN system for the analysis of mark-recapture data from Jolly-Seber type experiments. The previous versions (POPAN-3 for SUN/OS workstations and POPAN-PC for IBM-PC running DOS or Windows) included general statistics gathering and testing procedures, a wide range of analysis options for estimating population abundance, survival and birth parameters, and a general simulation capability. POPAN-4 adds a very general procedure for fitting constrained models based on a new unified theory for Jolly-Seber models. Users can impose constraints on capture, survival and birth rates over time and/or across attribute groups (e.g. sex or age groups) and can model these rates using covariate models involving auxiliary variables (e.g. sampling effort).
