Security level,potential level,expected utility: A three-criteria decision model under risk

Among the violations of expected utility (E.U.) theory which have been observed by experimenters, the violations of its independence axiom is, by far, the most common. It seems that, in many cases, these inconsistencies can be ascribed to the desire for security - called the security factor by L. Lopes (1986) - which makes people attach special importance to the worst outcomes of risky decisions as well as to the sole outcomes of riskless decisions (certainty effect). J.-Y. Jaffray (1988) has proposed a model which generalizes E.U. theory by taking into account this factor and is then able to account for certain violations. However, especially in experiments on choice involving prospective losses, violations of the von Neumann-Morgenstern independence axiom cannot be explained by the security factor alone and have to be partially ascribed to the potential factor (L. Lopes, 1986) which reflects heightened attention to the best outcomes of decisions, especially when the best outcome is the status quo. In this paper, we construct an axiomatic model for subjects taking into account simultaneously or alternatively the security factor and the potential factor. For this, as in Jaffray's model, it has been necessary to weaken not only the standard independence axiom but also the continuity axiom and, in the same time, to reinforce the dominance axiom. In the resulting model, choices are partially determined by the mere comparison of the (security level, potential level) (i.e. the (worst outcome, best outcome)) pairs offered, and completed by the maximization of an affine function of the expected utility, the coefficients of which depend on both the security level and potential level.In this model, a decision maker who (i) has constant marginal utility for money, (ii) is sensitive to the security factor alone in the domain of gains, (iii) is sensitive to the potential factor alone in the domain of losses, behaves as a risk averter for gains and a risk seeker for losses.     

The Cognitive Domain of the Quality of Life of University Students: A Re-Analyses of an Instrument

This paper presents the re-analysis of a previouslypublished instrument, based on Bloom's taxonomy,developed to measure the cognitive domain of thequality of life of university students. The items inthis instrument were assessed using Guttman's SmallestSpace Analysis. The findings generally supportBloom's conceptualization, identifying 5 of 6dimensions in the taxonomy: Knowledge, Comprehension,Application, Analysis, and Evaluation. The findingsprovide support for the enduring utility of Bloom'staxonomy, and reinforce the ongoing need to testtheoretically informed instruments using sophisticatedstatistical techniques.

A feminist perspective on COVID‐19 and the value of care work globally

The shared response to the COVID‐19 crisis demonstrates that the vast majority of society believes human wellbeing — not economic growth — should be at the centre of policy. COVID‐19 exposes the foundational role of care work, both paid and unpaid, to functioning societies and economies. Focusing on ‘production’ instead of the sustainable reproduction of human life devalues care work and those who perform it. Women’s physical and mental health, and the societies that rely on them, are at stake. When these policies are formulated, the field of feminist economics has valuable lessons for mitigating hardships as countries navigate the related economic fallout. A comprehensive response to the COVID‐19 crisis must recognize this gendered work as an integral part of the economic system that promotes human wellbeing for all.     

Village on the Border, anthropology at the crossroads: the significance of a classic British ethnography

Village on the Border was the seminal anthropological study of a mainland British rural community. It was written and published during a period of unsurpassed scholarship and creativity in British social science. To explain the impact it had on social anthropology, British studies and public discourse at the time, I look at the influences on Ronnie Frankenberg and his work of the then state of social anthropology; of the particular academic environment in which he was trained and worked; and of his personal background and political convictions. This analysis shows that although the book clearly bears particular historical and intellectual influences, it was explicitly set within comparative ethnographic frameworks, and in due course greatly influenced work elsewhere. Both methodologically and substantively, it should be seen as a significant contribution to the comparative study of local‐level politics, gender relations and the role of the ‘stranger’, as well as the authentic origin of modern anthropological studies of rural Britain.     

Determinants of International Migration Flows to and from Industrialized Countries: A Panel Data Approach Beyond Gravity1

We quantified determinants of international migratory inflows to 17 Western countries and outflows from 13 of these countries between 1950 and 2007 in 77,658 observations from multiple sources using panel-data analysis techniques. To construct a quantitative model that could be useful for demographic projection, we analyzed the logarithm of the number of migrants (inflows and outflows separately) as dependent variables in relation to demographic, geographic, and social independent variables. The independent variables most influential on log inflows were demographic [log population of origin and destination and log infant mortality rate (IMR) of origin and destination] and geographic (log distance between capitals and log land area of the destination). Social and historical determinants were less influential. For log outflows from the 13 countries, the most influential independent variables were log population of origin and destination, log IMR of destination, and log distance between capitals. A young age structure in the destination was associated with lower inflows while a young age structure in the origin was associated with higher inflows. Urbanization in destination and origin increased international migration. IMR affected inflows and outflows significantly but oppositely. Being landlocked, having a common border, having the same official language, sharing a minority language, and colonial links also had statistically significant but quantitatively smaller effects on international migration. Comparisons of models with different assumed correlation structures of residuals indicated that independence was the best assumption, supporting the use of ordinary-least-squares estimation techniques to obtain point estimates of coefficients.     

Modeling distances between humans using Taylor’s law and geometric probability

Taylor’s law states that the variance of the distribution of distance between two randomly chosen individuals is a power function of the mean distance. It applies to the distances between two randomly chosen points in various geometric shapes, subject to a few conditions. In Réunion Island and metropolitan France, at some spatial scales, the empirical frequency distributions of inter-individual distances are predicted accurately by the theoretical frequency distributions of inter-point distances in models of geometric probability under a uniform distribution of points. When these models fail to predict the empirical frequency distributions of inter-individual distances, they provide baselines against which to highlight the spatial distribution of population concentrations.
