Parental transfers and the labor supply of children

To finance their personal consumption, children may rely on transfers in the form of pocket money made by their parents and on personal resources earned from labor market activities. In this paper that focuses on the interaction between these two sources of income, we consider a model of parental transfer where the child can choose his own income through labor supply. The parent commits to a transfer amount that the child takes as given. For our empirical analysis, we use a cross-sectional French survey that includes detailed information about pocket money from parents to schoolchildren. Using a maximum-likelihood method, we estimate a simultaneous-equations model and find that parental transfers do not significantly influence the child's labor supply.     

Positive and negative preferences in human mate selection

This paper focuses on preferences for specific characteristics in a potential partner using data from 1993 to 1999 provided by a French marriage bureau. We perform an econometric analysis of the various traits either sought or rejected in a potential partner, respectively by men and women. Our results are consistent with investment in marriage. On the one hand, men tend to reject vulgar and unfaithful women, meaning that they are likely to suffer serious fitness costs from infidelity. On the other hand, women dread meeting potential partners who are alcoholic, selfish or violent.     

The Citizenship of Excluded Groups: Challenging the Consumerist Agenda

The language of consumerism suggests that through involvement in consumer processes, consumers can influence policy formation and service provision. This paper examines, as illustrative cases in Australia, how two groups of consumers, people with a mental illness and older people, engage with these consumer processes. It finds they critically evaluate the opportunity offered by consumer processes for inclusion in policy and programmes. Both people with a mental illness and interviewed older people indicated how they acted as "agents involved in interpreting their needs", despite finding that in consumer processes their needs were predefined. Rather than allowing themselves to be constructed as passive objects, they positioned themselves as active citizens, having agency not as individual consumers but through drawing on networks. The responses of both groups go some distance toward dismantling power differences between professionals and "consumers", suggesting that social policy and programmes for both people with mental illness and older people can and sometimes do develop in a context of greater inclusivity.     

Predicting online gambling self-exclusion: an analysis of the performance of supervised machine learning models

As gambling operators become increasingly sophisticated in their analysis of individual gambling behaviour, this study evaluates the potential for using machine learning techniques to identify individuals who used self-exclusion tools out of a sample of 845 online gamblers, based on analysing trends in their gambling behaviour. Being able to identify other gamblers whose behaviour is similar to those who decided to use self-exclusion tools could, for instance, be used to share responsible gaming messages or other information that aids self-aware gambling and reduces the risk of adverse outcomes. However, operators need to understand how accurate models can be and which techniques work well. The purpose of the article is to identify the most accurate technique out of four highly diverse techniques and to discuss how to deal analytically and practically with a rare event like self-exclusion, which was used by fewer than 1% of gamblers in our data-set. We conclude that balanced training data-sets are necessary for creating effective models and that, on our data-set, the most effective method is the random forest technique which achieves an accuracy improvement of 35 percentage points versus baseline estimates.     

Deleuze and the grandeur of Palestine: Song of Earth and Resistance

The article re-examines the Deleuzian concept of cartography and opens on the question of that race a fortiori minor called to philosophy and the constitution of an earth. Who are these people? Who are these people who, according to Deleuze, are missing? What is their name and what is their territory? The problem of minorities, “of the missing people”, analysed by Deleuze through Kafka finds a resonance and a quite particular affinity – and in this way a designation and a name – through the struggle of the Palestinian people; deterritorialized, “inferior, dominated, always becoming”. Deleuze’s pro-Palestinian engagement in no way manifests a rupture between philosophy and politics, but establishes itself as the essential correlate of a philosophically dynamic, creative and resistant reflection whose tenor has been constantly written into the realm of politics. After nearly 30 years, Deleuze’s pro-Palestinian positions are today the object of severe criticism, if not a cabal, launched by Eric Marty and Roger-Pol Droit, who aim at exhuming Deleuze’s philosophical corpus in order to extract from it a so-called “anti-Semitic complacency”.     

Physical and psychosocial indicators among office workers from public sector with and without musculoskeletal symptoms

Work-related musculoskeletal disorders (WRMD) are the result of the combination of different risk factors. They are very common among computer workers, mainly when neck and upper limbs are considered. Forty-two office workers from a public university participated in this study. They were divided into two groups: Symptomatic Subjects (SS, n=20) and Asymptomatic Subjects (AS, n=22), according to the Nordic Musculoskeletal Questionnaire (NMQ). Psychosocial indicators were assessed using the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES). Workplaces were evaluated according to the Ergonomic Workplace Analysis (EWA), proposed by the Finnish Institute of Occupational Health. The NMQ showed higher weekly prevalence of complaints on neck, shoulders and wrist/hands (p=0.00) among SS. The annual prevalence of symptoms on wrist/hands was also higher among SS (p=0.02). The JCQ did not show any difference between groups (p>0.05). Higher proportion of servers with 'high level' of engagement, dedication and absorption, according to UWES, was identified among SS (p<0.01). EWA showed worse scores for 'Work Site', 'Job Content' and 'Repetitiveness of the Work' among SS (p<0.05). Servers are exposed to physical and psychosocial risk factors that can contribute to the development of WRMD. Work conditions need to be change in order to improve musculoskeletal health.     

Effects of wearing a pressure redistribution belt while lying in a hospital bed

Bedsores (ulcers) are caused by multiple factors which include, but are not limited to; pressure, shear force, friction, temperature, age and medication. Specialised support services, such as specialised mattresses, sheepskin coverings etc., are thought to decrease or relieve pressure, resulting in a lowering of pressure ulcer incidence [3]. The primary aim of this study was to compare the upper/central body pressure distribution between normal lying in a hospital bed versus the use of a pressure redistribution belt. The study involved 16 healthy voluntary subjects lying on a hospital bed with and without wearing the belt. Results showed that the use of a pressure redistribution belt results in reduced pressure peaks and prevents the pressure from increasing over time.     

Online epistemic communities: theoretical and methodological directions for understanding knowledge co-elaboration in new digital spaces

This paper presents, illustrates and discusses a generic framework for studying knowledge co-elaboration in online epistemic communities ("OECs"). Our approach is characterised by: considering knowledge co-elaboration as a design activity; distinguishing discussion and production spaces in OECs; characterising participation via the notion of role; fine-grained analyses of meaning, content and communicative functions in interactions. On this basis, three key issues for ergonomics research on OECs are discussed and illustrated by results from our previous studies on OSS and Wikipedia. One issue concerns the interrelation between design (task) and regulation. Whereas design task-oriented activity is distributed among participants, we illustrate that OCEs function with specialised emerging roles of group regulation. However, the task-oriented activity also functions at an interpersonal level, as an interplay of knowledge-based discussion with negotiation of competencies. Another issue concerns the foci of activity on the (designed) knowledge object. Based on a generic task model, we illustrate asymmetry and distinctiveness in tasks' foci of participants. The last issue concerns how design-use mediation is ensured by specific forms of mediation roles in OECs. Finally we discuss the degree of generality of our framework and draw some perspectives for extending our framework to other OECs.
