A note on decisions under uncertainty: the impact of the choice of the welfare measure

The paper addresses the question, how policy decisions under uncertainty depend on the underlying welfare concept. We study three different welfare measures: The first is directly based on the ex ante (expected) utility of a representative consumer whereas the second relies on an ex ante and the third on an ex post valuation of policy changes compared to the status quo. We show that decisions based on these measures coincide if and only if risk-neutral expected utility maximization is applied. Differences between the decisions are analyzed for both, risk-averse expected utility maximization and the MaxiMin criterion. For risk-averse decision makers, differences between the first and the second concept arise if the absolute risk-aversion of the decision maker is not constant in income. For risk-aversion and the MaxiMin criterion, the effort levels to provide a public good based on an optimization of ex post utility changes exceed those based on the first or second concept. Implications for environmental policy decisions based on the concepts of abatement costs and benefits from abatement are discussed.     

Management of school locations allowing for free school choice

Nearly without exception, we find in literature (school) location models with exogenously given demand. Indeed, we know from a large number of empirical studies that this assumption is unrealistic. Therefore, we propose a discrete location model for school network planning with free school choice that is based on simulated utility values for a large average sample. The objective is to maximize the standardized expected utility of all students taking into account capacity constraints and a given budget for the school network. The utility values of each student for the schools are derived from a random utility model (RUM). The proposed approach is general in terms of the RUM used. Moreover, we do not have to make assumptions about the functional form of the demand function. Our approach, which combines econometric and mathematical methods, is a linear 0–1 program although we consider endogenous demand by a highly non-linear function. The proposed program enables practicing managers to consider student demand adequately within their decision making. By a numerical investigation we show that this approach enables us to solve instances of real size optimally – or at least close to optimality – within few minutes using GAMS/Cplex.     

Associations Between Maternal Postpartum Depression,Infant Social Behavior With a Stranger,and Infant Cognitive Development

Maternal postpartum depression (PPD) has been found to be related to infant social withdrawal during mother–infant interaction, and this may spill over on infant interactive behavior in other social contexts and impact infant psychosocial development. We investigated whether PPD was associated with infant social withdrawal during interaction with a tester in a psychological test situation and whether infant social withdrawal in the test situation mediated the association between PPD and infant cognitive scores reported in a previous study. Participants were 28 PPD dyads and 41 control dyads. We assessed infant social behavior and cognitive development with the Alarm Distress Baby Scale and the cognitive scale of the Bayley Scales of Infant and Toddler Development, third edition, at four months. More symptoms of maternal depression were associated with more infant social withdrawal. The association between maternal depressive symptoms and cognitive scores was at most partially mediated by infant social withdrawal in the test situation (<29.6%). Our results add to the existing literature on the effects of PPD on infant social behavior in other contexts than the one constituted by the mother. More research is needed to shed light on the mechanisms through which PPD impacts infant cognitive development.     

Employment commitment among the long-term unemployed in norway: Is a culture of dependency about to develop?

This paper explores the association between employment commitment and employment status, with a focus on the long-term unemployed. It has been claimed in some quarters that there has been a decline in the work ethic and a parallel development of a culture of dependency. Our data indicate that employment commitment seems to be influenced by previous and present work experiences, but factors such as sex and household circumstances are also of importance. There appears to be no association between unemployment duration or receipt of unemployment benefits and employment commitment. Even persons with a marginal attachment to the labour market are highly committed to employment. There is little evidence indicating that a decline in employment commitment is likely to take place. Overall, unemployment commitment among young people was as high as that found among older age groups. There are no signs of the development of a culture of dependency and a reduced work ethic. Our data further suggest that it may be possible to reverse low employment commitment among marginal categories by offering them meaningful paid work.     

Work situation operative model MOST: linking diagnosis and intervention to improve work conditions

This paper presents the model "Work Situation Operative Model" - MOST (after its Spanish acronym). It offers a comprehensive, systemic approach to analysing work stations and/or work processes, serving also as a framework for pursuing various ergonomic and occupational health and safety goals. Originally produced for a food sector company, the model has been extended and successfully applied in several industries in Colombia and Ecuador, including cement, oil, and paper industries. Based on a systemic understanding of work systems and tasks, the model not only allows different, commonly-used methods and tools for evaluating or assessing the risk of muscular-sketetal disorders to be included, but also supports occupational risk management strategies. Hence, one of its more important contributions relies on providing meaningful information that is useful for improving the work station and/or work process through design and re-design, by focusing on the interactions between all system elements.     

Saving water to save the environment: contrasting the effectiveness of environmental and monetary appeals in a residential water saving intervention

To convince people to reduce their energy consumption, two types of persuasive appeals often are used by environmental organizations: Monetary appeals (i.e., ‘conserving energy will save you money’) and environmental appeals (i.e., ‘conserving energy will protect the environment’). In this field study we aimed to compare the effects of monetary and environmental appeals on showering habits. During two weeks we measured showering behavior in one hundred households. As compared to monetary appeals, environmental appeals were more effective in decreasing participants’ shower frequency. Interestingly, the monetary appeal was judged as somewhat more motivating to save water than the environmental appeal. We discuss theoretical and practical implications of these findings.     

Embedded Diasporas: Shaping the Geopolitical Landscape

This research argues that the capitalistic world-economy, advantageous to the core nations of World Systems Theory, is simultaneously rebalancing inequalities for semi-peripheral nations through a diasporic mechanism that builds reciprocal embeddedness. This is a challenge to world systems theorists' predominant view that the state class structure is fixed. This research adds to international networks research, extending World Systems Theory by building on and integrating the concept of reciprocal embeddedness at the interorganizational and international levels. A diaspora, explicated as one that is organized toward political action, becomes embedded in a core host, uses the host's influence to reduce state class differences, builds a status-equalizing intercultural channel, and induces an agenda for its homeland.     

Creating shared spaces: developing teaching through peer supervision groups

Abstract

This article examines how university teachers from different disciplines and faculties collaborate by giving feedback on each other’s teaching. This collaborative activity, termed Peer Supervision Groups (PSG), is part of a faculty development course at a Norwegian university. Conceptually the study draws on activity theoretical notions of boundary crossing and boundary objects and is empirically based on observations of a PSG over a period of six months. The article examines how collaborative interactions about teaching across communities emerge in the PSG setting and how this arrangement can be improved for the benefit of developing teaching practices in higher education.
