Individual Motivation, its Nature, Determinants and Consequences for Within Group Behavior

The paper deals with evaluating the adequacy of the assumption that in economic transactions people are self-interested insofar as they are motivated solely by the concern of maximizing their own utility, and in particular with assessing how this assumption affects within-group behavior. Policy and incentive structures based on the assumption of exogenous and self-interested motivation can undermine other sources of motivation and have negative effects both on cooperative behavior and also on economic efficiency. The paper sketches the motivational assumption of homo œconomicus: in the classical formulation, in rational choice theory and in Becker’s later work which introduces personal and social capital into the individual utility function. It then challenges the position that homo œconomicus contains an adequate characterization of human motivation for cooperative within-group behavior. It introduces alternative motivational behaviors: philia and altruism, identity and self-expression, moral rules, intrinsic motivation and social norms. It argues that motivations are complex and multiple; a single assumption of utility maximization is insufficient for policy purposes. As the individual is always a social being, how she behaves will be dependent on the social context in which she is acting. If motivations are endogenous, and if under certain conditions maximizing motivation displaces other sources of motivation, then these indirect effects, and their long term consequences for efficiency and equity, should be taken into account in framing economic policies.Motivation; Rational Choice; Self-Interest; Cooperation

Curriculum change in modern foreign languages education in England: barriers and possibilities

This paper considers the languages on offer in secondary schools in England and the possibility of enacting curriculum change with a view to reducing the dominance of French, Spanish and, to a lesser extent, German as a possible way to increase take-up of modern foreign languages post-14. Questionnaires were completed by 666 students aged 14-15, 70 head teachers and 119 heads of modern languages in secondary schools throughout England, investigating students’ views as to the languages they would like to learn and their views of particular languages as well as the views of senior and middle leaders on the factors which impact on the teaching of modern languages. The paper concludes that students are interested in a wider range of languages than is currently available, for reasons primarily relating to usefulness. It also finds that schools are constrained by operational concerns preventing them fully considering the possibility of teaching a wider range of languages. Implications for national-level language policy and the culture of school accountability are discussed

Walls of glass. Measuring deprivation in social participation

Altres ajuts: RI441/6-1This paper proposes a measure for deprivation in social participation, an important but so far neglected dimension of human well-being. Operationalisation and empirical implementation of the measure are conceptually guided by the capability approach. Essentially, the paper argues that deprivation in social participation can be convincingly established by drawing on extensive non-participation in customary social activities. In doing so, the present paper synthesizes philosophical considerations, axiomatic research on poverty and deprivation, and previous empirical research on social exclusion and subjective well-being. An application using high-quality German survey data supports the measure's validity. Specifically, the results suggest, as theoretically expected, that the proposed measure is systematically different from related concepts like material deprivation and income poverty. Moreover, regression techniques reveal deprivation in social participation to reduce life satisfaction substantially, quantitatively similar to unemployment. Finally, the validity of the measure and the question of preference vs. deprivation are discussed

FDI and the Relevance of Spatial Linkages: Do third Country Effects Matter for Dutch FDI?

The aim of this paper is to test for the relevance of spatial linkages for Dutch (outbound) FDI. To do so, and based on recent FDI theories, we estimate a spatial lag model to assess the importance of spatial linkages for Dutch FDI to 18 host countries. As a determinant of FDI, space or geography also enters our empirical analysis through the market size and a corporate income tax variable. Our paper is among the few to date to take spatial linkages with respect to FDI into account. The Dutch case is also interesting because Dutch firms account for a large part of global FDI and related research has so far focused mainly on US FDI. After controlling for fixed effects, we find for our sample period 1984-2004 that third country effects matter, but the results are somewhat sensitive to sample and model selection. Apart from our benchmark spatial lag model, we discuss and estimate various alternative models notably by looking at European host FDI countries only, by dividing FDI into industry and services FDI and by estimating a spatial error model as well.

Leveraging Mixed Expertise in Crowdsourcing.

Crowdsourcing systems promise to leverage the "wisdom of crowds" to help solve many kinds of problems that are difficult to solve using only computers. Although a crowd of people inherently represents a diversity of skill levels, knowledge, and opinions, crowdsourcing system designers typically view this diversity as noise and effectively cancel it out by aggregating responses. However, we believe that by embracing crowd workers' diverse expertise levels, system designers can better leverage that knowledge to increase the wisdom of crowds. In this thesis, we propose solutions to a limitation of current crowdsourcing approaches: not accounting for a range of expertise levels in the crowd. The current body of work in crowdsourcing does not systematically examine this, suggesting that researchers may not believe the benefits of using mixed expertise warrants the complexities of supporting it. This thesis presents two systems, Escalier and Kurator, to show that leveraging mixed expertise is a worthwhile endeavor because it materially benefits system performance, at scale, for various types of problems. We also demonstrate an effective technique, called expertise layering, to incorporate mixed expertise into crowdsourcing systems. Finally, we show that leveraging mixed expertise enables researchers to use crowdsourcing to address new types of problems.PhDComputer Science and EngineeringUniversity of Michigan, Horace H.

The effects of rearing conditions on sexual traits and preferences in zebra finches

Although theory predicts that females should prefer the highest quality male, female mating preferences within populations often show pronounced variation. What causes and maintains this variation remains poorly understood. This thesis addresses the influence of rearing conditions both on female mating preferences and male advertising signals in the zebra finch Taeniopygia guttata. It reconciles earlier apparently contradicting findings on the relative importance of visual versus acoustic signals by comparing females__ preferences across three commonly used testing contexts. It then goes on using brood size manipulations and operant conditioning tests to ask for the effects of developmental condition on sexual traits and preferences. Birds that were raised in small or large broods differed in adult morphology and physiology and adult behaviour: male advertising song and female mating preferences reflected developmental condition. Moreover, the mating behaviour of poor condition females provides the first experimental evidence of self-perceived attractiveness in animals influencing their partner choice. The results provide strong empirical support for theoretical models of state-dependent mate choice.This work was supported by the Research Council for Earth and Life Sciences (ALW, grant number 813.04.004) with financial aid from the Netherlands Organization for Scientific Research (NWO).UBL - phd migration 201

Principles for designing an effective, post-compulsory music curriculum suitable for Western Australia

A new post-compulsory Music course known as the Western Australian Certificate of Education (WACE) Music course was recently introduced into Year 11 and 12 in Western Australian (WA) schools. Following a convoluted process of creation, its implementation into classrooms has been problematic. Given criticism levelled at its process of creation and implementation, the researcher questions whether the WACE Music course embodies effective, recognised principles to support the effective teaching and learning of music. This study investigates the principles which should form the basis of an effective, post-compulsory music curriculum, suitable for WA. It involved a literature review which sought to produce a set of principles for teaching and learning frameworks based upon international best practice in music education, and applicable in the unique geographical, historical and multicultural WA context. In addition, the study employed a researcher–designed survey instrument to examine whether Western Australian music teachers perceived these principles to be evident in their practical experiences of the new WACE music course. With the subsequent publishing of a draft Australian National Arts Curriculum, it is an appropriate time to review the principles which should underpin an effective Music curriculum for senior secondary students in the WA context because, without a clear set of guiding principles that are understood by curriculum writers, there is a possibility that following courses could be fundamentally flawed and not serve the best interests of students

The role of posterior parietal cortex in multisensory decision-making

Making a decision consists of committing to a plan of action, usually selected between two or more competing alternatives. Numerous fields have studied the processes involved in decision-making including psychology, economics, philosophy and statistics, to name only a few. In neuroscience the study of decision-making has been extremely fruitful in recent years and has focused on two main aspects: (1) perceptual decisionmaking, interested in understanding how external information is perceived by the sensory systems and used to make decisions; (2) value based decision-making, interested in the mechanisms that cause and result from the association of subjective values to the possible outcomes of a decision.(...
