Die Low-Cost-Hypothese

The Low-Cost-Hypothesis (LCH) postulates that the effect of attitudes on behavior varies with the costs at stake in the situation. The effect is deemed to be higher in low-cost-situations, compared to high-cost-situations. We argue that a closer look at the literature reveals two distinct versions of the LCH, which have not been disentangled so far. We reconstruct both versions ?C the ??simple?? and the ??specific?? version of the LCH ?C and discuss their theoretical foundations and empirical implications. The ??simple?? version can be derived from a simple expected utility model. In this model, attitudes and (tangible) behavioral costs exert independent effects on the net utility of the action alternatives. A conditional effect of the attitudes that depends on the behavioral costs only exists with respect to the probability of choosing an action alternative. However, this dependence of marginal effects on the actor??s initial level of utility or probability holds for any independent variable or utility argument. A second, ??specific?? version of the LCH postulates a variable-specific interaction effect between attitudes and costs. We point to the problems of previous approaches to deriving such a specific hypothesis and identify dual-process-theories as an alternative theoretical foundation that allows understanding the limited scope conditions of the specific LCH. The article carries important conclusions for empirical applications and tests of the LCH in diverse fields of sociological research and, more generally, for the decision-theoretic analysis of social action.     

The Shag‐Band Menace: Tracing the Spread of a Contemporary Legend

The internet enables analysts to better track rumors and contemporary legends through time and space. Comments about sex bracelets reveal waves of concentrated attention; the spread of particular variants display a similar pattern. The diffusion of such stories reflects constructions of childhood and adolescent sexuality as social problems.     

Data Sets on International Migration

International migration figures prominently on the agenda of the United Nations. Solid migration data are crucial for supporting this global debate. This article describes the international migration data sets produced by the Population Division, Department of Economic and Social Affairs, United Nations. The Population Division’s Migration Section produces migrant stock estimates for the world’s countries by sex and, more recently, by age. The Section also produces a database containing annual data on inflows, outflows, and net flows of international migrants by country of origin for major destination countries. The Section maintains the Global Migration Database, containing the world’s most complete set of empirical statistics on the international migrant stock by country of birth, citizenship, sex, and age for more than 200 countries and territories for recent decades. The data and associated publications are available from the Migration Section’s Web site at http://www.unmigration.org .     

Youth Identity Formation: Contemporary Identity Work

The study of youth identity and its formations today is diffuse and widely expansive, charted across a variety of disciplines, including Sociology, Anthropology, Psychology, Education, History, English, and Cultural Studies. This review essay is largely concerned with youth identity formation as a socially bound process as understood by sociologists. I sketch some of the thematic currents that guide contemporary sociologists’ investigations of youth identity formation as socially constituted process, and some of its exemplars. I highlight two conceptual framings of note: (a) youth identity formation as ‘project’ captured in the concept of ‘identity work’ and (b) youth identity formation as historically contingent phenomenon shaped by changes to the life course and changes in conceptions of the self in late modernity.     

The silence of numbers: A split-sample experiment concerning respondents' linguistic sensitivity in Danish survey studies

This article presents, for the first time in English, findings from a Danish research project on language comprehension and memory as generators of measurement problems in sociological and other social-science survey studies. Utilizing survey questionnaires as instruments of measurements, the article deals with the linguistic sensitivity of Danish adults and the measurement problems it entails. The article uncovers the nature and extent of statistically significant response differences due to moderate linguistic changes. The article problematizes the trustworthiness of Danish social-science survey studies and provides evidence that respondents' answers to survey questions depend to a marked extent on the latter's wording. The empirical basis is a split-sample experiment in which 1900 respondents completed two versions of the 'same' questionnaire.     

Restricted domination parameters in graphs

In a graph G, a vertex dominates itself and its neighbors. A subset S ⊂eqV(G) is an m-tuple dominating set if S dominates every vertex of G at least m times, and an m-dominating set if S dominates every vertex of G−S at least m times. The minimum cardinality of a dominating set is γ, of an m-dominating set is γ _m , and of an m-tuple dominating set is mtupledom. For a property π of subsets of V(G), with associated parameter f_π, the k-restricted π-number r _k (G,f_π) is the smallest integer r such that given any subset K of (at most) k vertices of G, there exists a π set containing K of (at most) cardinality r. We show that for 1< k < n where n is the order of G: (a) if G has minimum degree m, then r _k (G,γ _m ) < (mn+k)/(m+1); (b) if G has minimum degree 3, then r _k (G,γ) < (3n+5k)/8; and (c) if G is connected with minimum degree at least 2, then r _k (G,ddom) < 3n/4 + 2k/7. These bounds are sharp. Research supported in part by the South African National Research Foundation and the University of KwaZulu-Natal.     

When near means related: evidence from three web survey experiments on inter-item correlations in grid questions

In this article, we present the results of three question design experiments on inter-item correlations, which tested a grid design against a single-item design. The first and second experiments examined the inter-item correlations of a set with five and seven items, respectively, and the third experiment examined the impact of the question design on inter-item correlations of follow-up questions. We found that the inter-item correlations in grid designs were higher for both the set of five and seven items than for questions in a single-item design. Additionally, the inter-item correlations of the set of follow-up questions were higher if the preceding set of questions was presented in a grid. According to the findings of the present research, respondents seem to apply the interpretative near means related heuristic when answering grid questions, and also when answering follow-up questions preceeded by grid questions.     

Could EGM player-tracking systems help link gamblers to treatment services in Australia: a thematic analysis of counsellor and community educators’ perspectives

There are a number of different pathways to care that people experiencing problems with gambling may pursue. The current research examined the potential of player-tracking systems, such as pre-commitment technology or loyalty cards, to improve the delivery of links to treatment. Thirty-three key informants from gambling treatment and community education in Australia were interviewed about the potential contributions of these technologies to helping link gamblers with problems to treatment services. Thematic analysis revealed three broad considerations for effective links to treatment using these technologies. First, links need to be appropriate in terms of the multitude of problems (other than gambling) that people might face with customized links appropriate to a gambler’s circumstances. Second, the presentation of the links should make them easy to notice and appropriately timed. Third, links should be provided as part of a broader strategy of harm minimization; by recognizing where people are in terms of behavioural change; providing positively framed guidance; and maintaining consistency with public health approaches. This research provides guidance based on informed expert opinion on what features of technology-driven links-to-treatment are likely to meet with greatest success.     

Middle-Range Future Claims: Constructing the Near-Future Consequences of COVID-19

The extraordinary social and economic impact of the COVID-19 pandemic has generated many claims about the middle-range future—the period beginning in the late summer or early fall of 2020 and projected to last for some months or years. This paper surveys those assertions and seeks to explain the factors that led to them. Exploring questions about future claims can expand the scope of social problems theory.
