Probability weighting and the ‘level’ and ‘spacing’ of outcomes: An experimental study over losses

The main goal of the experimental study described in this paper is to investigate the sensitivity of probability weighting to the payoff structure of the gambling situation—namely the level of consequences at stake and the spacing between them—in the loss domain. For that purpose, three kinds of gambles are introduced: two kinds of homogeneous gambles (involving either small or large losses), and heterogeneous gambles involving both large and small losses. The findings suggest that at least for moderate/high probability of loss do both ‘level’ and ‘spacing’ effects reach significance, with the impact of ‘spacing’ being both opposite to and stronger than the impact of ‘level’. As compared to small-loss gambles, large-loss gambles appear to enhance probabilistic optimism, while heterogeneous gambles tend to increase pessimism.

Taking Stock of Monitoring and Evaluation Arrangements in the Context of Poverty Reduction Strategy Papers: Evidence from 20 Aid‐Dependent Countries in Sub‐Saharan Africa

Shifts in thinking and practice concerning aid have posed serious challenges in monitoring and evaluation (M&E) for both donors and recipients, but progress in reform remains slow. An important first step in any initiative involving M&E capacity development is the diagnosis of the systems' current status. This article presents a diagnostic checklist that captures issues of M&E policy: indicators, data collection and methodology; organisation; capacity‐building; participation of nongovernmental actors; and use. It applies it to a review of the PRSP M&E arrangements of 20 aid‐dependent countries in sub‐Saharan Africa to demonstrate comparative strengths and weaknesses.     

Cultures of care? Animals and science in Britain

It is becoming increasingly common to hear life scientists say that high quality life science research relies upon high quality laboratory animal care. However, the idea that animal care is a crucial part of scientific knowledge production is at odds with previous social science and historical scholarship regarding laboratory animals. How are we to understand this discrepancy? To begin to address this question, this paper seeks to disentangle the values of scientists in identifying animal care as important to the production of high quality scientific research. To do this, we conducted a survey of scientists working in the United Kingdom who use animals in their research. The survey found that being British is associated with thinking that animal care is a crucial part of conducting high quality science. To understand this finding, we draw upon the concept of ‘civic epistemologies’ (Jasanoff 2005; Prainsack 2006) and argue that ‘animals’ and ‘care’ in Britain may converge in taken‐for‐granted assumptions about what constitutes good scientific knowledge. These ideas travel through things like state regulations or the editorial policies of science journals, but do not necessarily carry the embodied civic epistemology of ‘animals’ and ‘science’ from which such modes of regulating laboratory animal welfare comes.     

Event-driven production scheduling in SME

One common problem among Small and Medium Enterprises (SME) is to don’t have at disposal formal and simple approaches for production scheduling, especially in case of an event that introduces the requirement of a re-planning. The paper approaches this kind of event-driven re-scheduling problems at the arrival of a new order, when some jobs are under processing, some operation have already finished and other jobs are waiting to be loaded on a machine. For a simple application in a SME, to the operations already started and completed for a job a processing time equal to zero is assigned; the operations already started but not yet completed are interrupted and considered as operations that must be executed for the remaining part of their processing time; all the other jobs are considered for the event-driven job-shop re-scheduling problem. A validation of the procedure in a realistic application is presented.     

Rapport: Little effect on children’s,adolescents’, and adults’ statement quantity,accuracy, and suggestibility

Abstract

Rapport building is widely recommended in eyewitness interview situations and is a critical component in some interview protocols. However, empirical evidence on the effectiveness of rapport building on memory performance is scant. The current experiment examined the effects of different levels of rapport (none, minimal, extensive) on children’s, adolescents’, and adults’ memory (N?=?229). Participants viewed a video of a mock theft and received one of three possible rapport manipulations. They then provided a free narrative of what they had seen, followed by 18 cued (suggestive and nonsuggestive) questions. In general, we found limited evidence of positive effects of rapport building on statement quantity and accuracy across age groups. Adolescents did profit more from extensive rapport building compared to no rapport. In line with the idea of a linear development of memory measures with age, adolescents generally fell in-between the other two age groups across different memory measures. The current study encourages systematic experimental research on the effect of rapport building on eyewitness memory.

Education, gender, and migration in the context of social change

Although sociologists have identified education as likely determinant of migration, the ways in which education affects migration are unclear and empirical results are disparate. This paper addresses the relationship between educational attainment, enrolment, and migration, focusing on the role of gender and how it changes with evolving social contexts. Using empirical analyses based in Nepal, results indicate that educational attainment has positive effects and enrolment has negative effects on out-migration and including enrolment in the model increases the effect of attainment. In the case of women, with the changing role of gender, increased education and labor force participation, the affect of educational attainment changes drastically over time, from almost no effect, to a strong positive effect. Consideration of enrolment, and the role of gender in education, employment, and marriage may help to explain the disparate results in past research on education and migration.     

Zygmunt Bauman und die Geschlechterforschung: Eine viel versprechende Liaison?

Bauman’s work plays an important role in post-modern and post-modernist sociology. However, his work has been barely discussed within feminist and gender theory. In my article, I offer a critical reading of Bauman’s work in the light of recent feminist debates concerning theories of subjectivation and discourse (esp. by Butler and Braidotti). This reading shows that, while Bauman’s notion of postmodernity as social diagnosis is much less subtle than gender theory has proven to be, his work on postmodernism is indeed quite along the lines of post-structuralist and post-modern feminist theory.     

Does any mother’s body odor stimulate interest in mother’s face in 4‐month‐old infants?

Little is known about the effects of olfaction on visual processing during infancy. We investigated whether and how an infant's own mother's body odor or another mother's body odor affects 4‐month‐old infants’ looking at their mother's face when it is paired with a stranger's face. In Experiment 1, infants were exposed to their mother's body odor or to a control odor, while in Experiment 2, infants were exposed to a stranger mother's body odor while their visual preferences were recorded. Results revealed that infants looked more at the stranger's female face in presence of the control odor but that they looked more at their mother's face in the context of any mother's body odors. This effect was due to a reduction of looking at the stranger's face. These findings suggest that infants react similarly to the body odor of any mother and add to the growing body of evidence indicating that olfactory stimulation represents a pervasive aspect of infant multisensory perception.     

Why Do Women's Wages Increase So Slowly Throughout Their Career? A Dynamic Model of Statistical Discrimination

Abstract. The aim of this paper is to explain the growing wage differentials between men and women during their working careers. We provide a dynamic model of statistical discrimination, which integrates specific human capital decisions: on‐the‐job training investment and wages are endogenously determined. We reveal a small wage differential at the beginning of women's career, but women's wages increase more slowly; this is partly due to a lower level of human capital investment by women and partly because firms smooth training costs between different periods.
