Commerce and Capitalism in Late Medieval England: Problems of Description and Theory*

Abstract Marx's account of the transition from feudalism to capitalism is usually handled too narrowly in discussions of the later Middle Ages. When its full scope is taken into account the period 1300–1530 is shown to be more a period of arrested development than one of critical importance. The period 1000–1300 showed a much greater shift towards capitalism. By implication, the transition needs analysing as a much longer process than most traditional accounts imply. The article also queries the coherence of accounts of late medieval change that refuse to give autonomous weight to declining population as a cause of social change.     

HEALTH CARE, INSURANCE, AND THE CONTRACT CHOICE EFFECT

This article explores the interdependence between the individual consumer's demand for medical care and choice of health insurance coverage, with emphasis on its implications for demand behavior and empirical analysis. We show that an increase in the price of medical care has two effects on demand, the usual response of reduced quantity demanded and a health insurance contract choice effect resulting from the consumer's incentive to change insurance plan. The contract choice effect, widely neglected in studies of medical care demand, alters both the quantitative and qualitative predictive properties of the consumer's demand for medical services.

Sport and globalization: transnational dimensions

Abstract The aims of this special issue are to both raise the social scientific status of sport and to advance understanding of transnational processes through the role of sport in global change. The Introduction argues that sport, like globalization, can be understood in transdisciplinary terms, and the papers included contributions informed by sociology, anthropology, political sciences and history. As well as placing the issue in the context of recent studies of sport and globalization, the Introduction outlines the seven papers. Placed together they move from analyses of broader globalizing and multi‐sport issues towards consideration of how transnational processes impact upon individual sports – with examples from cricket, baseball and association football – ending with regional and national dimensions.     

INNUMERACY ABOUT MINORITY POPULATIONS

We use a small but nationally representative sample to investigatethe sources of innumeracy regarding the proportion of blacks,Hispanics, and Jews in the U.S. population. In addition to anumber of standard demographic differences, we find that overestimatesare closely related to region as well as to the density of thelocal black/Hispanic population. The extent to which minoritypopulations are perceived as a kind of threat is also relatedto perceived proportions, though the direction of causalitycannot be determined. We discuss the meaningfulness of thesepopulation estimates and speculate on whether trying to improvethem would alter attitudes toward minorities.     

WHY THE DEMOCRAT-REPUBLICAN PARTISANSHIP GAP VARIES FROM POLL TO POLL

Polls taken in late 1980 and 1984 varied by up to 20 pointsin the spread they reported between Democratic and Republicanidentifiers. We found three systematic and sizable differencesacross polls: polls that sample only voters, polls that emphasize"today" or the present in their question wording, and pollsthat are taken close to election day (at least in circumstanceslike those of 1984) tend to favor the party currently advantagedin the presidential race.     

Parental Contact with Children Fostered and in Residential Care after the Children Act 1989

Correspondence to Andy Bilson, Department of Social Work and Social Policy, University of Northumbria, Newcastle NE7 7XA. E-mail Andy_Bilson{at}Unn.AC.UK Summary Research carried out since the implementation of the ChildrenAct 1989 based on a sample of 848 children looked after by localauthorities indicates that previous estimates of the numberswho have no contact with parents may have underestimated theextent of the problem, and that despite the emphasis placedon contact by the Children Act there is still much work to bedone to improve practice. The research not only confirms earlierfindings about the instability of placements in care but alsoshows differences in face to face contact which depend on thelength of time in care or accommodation and the reason for entry,as well as differences between children placed in residentialand foster care. Finally it was found that where children havespent long periods in care they tend to have little contactwith fieldworkers, and it is suggested that there is a needto redefine the social work agenda for this vulnerable groupof children.     

The "Positivity Bias" inEvaluations of Public Figures:Evidence Against Instrument Artifacts

The "positivity bias" is a term used to describe the consistentfavorable evaluation of public figures found in surveys overthe past 40 years. This paper explored several possible artifactualexplanations for this bias,focusing on the survey instrumentitself. Two experiments varied the labeling and ordering ofscale endpoints, the affective value of the initial contextevaluated, and the presence or absence of a prestigious jobtitle associated with the nameof the public figure. None ofthe variations produced significantly different levels of positivitythan the standard control condition used in each experiment.RichardR.

An algorithm for scheduling a chemical processing tank line

This paper presents a model and an algorithm for scheduling a system in which parts are processed through a chemical processing tank line. The tank line is equipped with one piece of material-handling equipment. The tank line is modelled with a mixed integer linear programming formulation. The formulation is then used to develop a heuristic algorithm. The algorithm generates the optimum or near optimum schedule and is easy to apply in practice where no defectives are permitted.
