In vast markets of developing economies, especially in South Asia, both seasonal rural migrants and threatened urban workers constitute a bulk of the new class of working poor and are truly marginal in terms of their socio-economic status. We argue that gift-giving and gift exchanges in labour markets can perpetuate both rural and urban poverty among the working poor. In the context of working ...

Authorship is a problem in film studies that simply will not go away. Despite all sorts of arguments reducing authors to abstract entities such as author-functions, fictional surrogates, and implied authors, and eventually abandoning them under the mantra of “the death of the author,” we have not been able in our critical and historical discourses to shrug off talking about films as if they are...

This paper presents our recent work with the Generalized Intelligent Framework for Tutoring (GIFT) for authoring tutors and training systems in concert with already developed external applications that provide a wide variety of educational experiences. In this paper, we describe our efforts to extend the GIFT system to develop metacognitive tutoring support for UrbanSim, a turnbased simulation ...

Fairness is a strong concern as shown by dictator and ultimatum experiments. Efficiency, measured by the sum of individual payoffs, is a potentially competing concern in games such as the prisoners’ dilemma. In our experiment participants can increase efficiency by gift giving. In the one-sided treatment this is only possible for one of the two partners. The two-sided treatment allows for mutua...

In the past, gift-giving has interested mainly anthropologists because it was taken to be a primitive mode of exchange. Recent contributions of economists acknowledge however that gift-giving is still present in modern exchange economies. In this paper gifts are characterized by motivations. Two main features of gift giving are to be explained: (in-)adequacy and (non-)reciprocity. It is argued ...

The aim of this paper to explain gift-giving by means of social approval. In a simple framework we are able to account for a number of stylized facts. These are that gift-giving is often reciprocal, that gifts tend to be inadequate, and that gift-giving is sometimes reduced after a monetary compensation is o¤ered. The implication for the interaction between gift-giving and the market institutio...

The number of authors per manuscript in peer-reviewed medical journals has increased substantially in the last several decades. Several reasons have been offered to explain this authorship growth, including increased researcher collaboration, honorary authorship driven by increased pressures for funding and promotion, the belief that including senior authors will facilitate publication, and the...

I recently gave a lecture to the faculty and house officers in my department on the topic of submitting a manuscript for publication. I covered how to choose a journal, the importance of following the instructions for authors, responsibilities of authorship, communications with the editor, misuse of figures and tables, linking cited references to Medline and PubMed, what happens at the journal ...
