There are many cognitive training tests purporting to both measure older people’s cognitive performance, several of which come with associated training that are deemed to improve cognition. This chapter describes cognitive tests that have been claimed to be linked to driver behaviour, and that training on them could improve driver behaviour. Of special interest are tests that could be completed at home on a computer, as it is suggested this could capture many individuals who are worried about attending a driver assessment centre and are not likely to be referred. Findings suggest that UFOV (Useful Field of View) Time Making Trail (A and B) and Dual N have research suggesting that training on them could improve driver performance for older drivers. However, the robustness of the research is debateable. There are also two physiological tests – a neck and shoulder and a general fitness test that also show promising results for improving driver performance. In addition, education and training is purported to improve driver behaviour, but although there is positive feedback from older people who attend and some short-term improvements, research on long-term improvements on driver behaviour are not yet evident. Overall, there are promising results from individual cognitive, physiological tests and from education and training suggesting that reflection on action and feedback from the task is important to improving driver performance but more research is needed.

The choice of high pin count ASIC packages has a major impact on the total cost and performance of the whole packaging system. Six different types of ASIC packages have been compared with respect to production aspects, availability, reliability, thermal and electrical properties and cost. Recommendations for the proper choice of packages for different types of applications are given. All packages have been directly assembled to PWBs in order to study problems with handling, solder process, testing and repairability. Some of the assembled packages have been temperature cycled in order to test the solder joint reliability. The pin grid array packages are the most frequently used high pin count packages today. However, they are expensive and through‐hole mounting reduces the routing capability of the board. Pad area array packages are a hermetic alternative with a lower price for the package as well as very good thermal and electrical properties, but they need to be mounted on expensive PWBs. Another surface mountable package which is hermetic is the ceramic leaded chip carrier with fine lead pitch. This package is even more expensive than the pin grid array package and is difficult to handle. In the future, non‐hermetic alternatives will probably predominate. Plastic quad flat pack and TapePak can be used below 160–180 leads, while direct assembled TAB would be the best alternative for very high pin counts. Before one can use non‐hermetic packages in telecom products, a large qualification programme must be performed to evaluate the long‐term reliability.

The purpose of this paper is to compare sickness presence (SP) and sickness absence (SA) regarding the strength of their relationship to health/ill‐health. In a previous Canadian study a stronger association between SP and health/ill‐health than between SA and health/ill‐health was shown.
Five Swedish data sets from the years 1992 to 2005 provided the study populations, including both representative samples and specific occupational groups (n=425‐3,622). Univariate correlations and multiple logistic regression analyses were performed. The data sets contained questions on SP and SA as well as on various health complaints and, in some cases, self‐rated health (SRH).
The general trend was that correlations and odds ratios increased regularly for both SP and SA, with SP showing the highest values. In one data set, SRH was predicted by a combination of the two measures, with an explained variance of 25 percent. Stratified analyses showed that the more irreplaceable an individual is at work, the larger is the difference in correlation size between SP and SA with regard to SRH. SP also showed an accentuated and stronger association with SRH than SA among individuals reporting poor economic circumstances.
The results support the notion that SA is an insufficient, and even misleading, measure of health status for certain groups in the labor market, which seem to have poorer health than the measure of SA would indicate.
A combined measure of sickness presence and absence may be worth considering as an indicator of both individual and organizational health status.

A growing body of social research analyzes how the biomedical interest in detailed molecular aspects of people's bodies (genes, biomarkers, DNA) affect everyday notions of health, risk, and responsibility for health problems. However, this research focus has been largely neglected in social alcohol research. The purpose of this paper is to report on some early findings from a study of media portrayals of biomedical alcohol research and to present a rationale for studying biomedical alcohol research more broadly.
The empirical discussion is based on textual analysis of 90 newspaper articles published in Swedish newspapers between 1995 and 2010 and one‐on‐one semi‐structured interviews with 24 newspaper readers about their interpretation of the newspaper portrayals. The motives for studying biomedical alcohol research more broadly are discussed in relation to existing research and theories of biomedicalization.
It is found that a large majority of the newspapers cite biomedical researchers to explain the mechanisms of addiction, and that biomedical research is often presented as revolutionary in scope. However, journalists also act as storytellers who explain the biomedical research results to readers. The reward system proved to be a central notion among the interviewees, who had their own, different and varying definitions of the concept. The authors suggest a framework for analyzing how biomedical knowledge is produced, communicated and utilized by three types of key actors.
The study presents a novel framework for studying biomedical alcohol research.

Transient eddy current formulations based on the Finite Integration Technique (FIT) for the magneto‐quasistatic regime are extended to include motional induction effects of moving conductors with simple geometries by different approaches. A new regularization of the formulation using discrete grad‐div augmentation of the curlcurl formulation is presented and tested. To improve the implicit time integration process, several schemes for an error controlled variable time step selection are presented and for the repetitive solution of the arising large sparse systems of equations a sparse direct solver is compared to iterative methods such as a preconditioned conjugate gradient method and a new algebraic multigrid solver, which is aware of the curlcurl nullspace.

Immigrant and native child poverty in Denmark, Norway, and Sweden 1993–2001 is studied using large sets of panel data. While native children face yearly poverty risks of less than 10 percent in all three countries and for all years studied the increasing proportion of immigrant children with an origin in middle- and low-income countries have poverty risks that vary from 38 up to as much as 58 percent. At the end of the observation period, one third of the poor children in Norway and as high as about a half in Denmark and in Sweden are of immigrant origin. The strong overrepresentation of immigrant children from low- and middle-income countries when measured in yearly data is also found when applying a longer accounting period for poverty measurement. We find that child poverty rates are generally high shortly after arrival to the new country and typically decrease with years since immigration. Multivariate analysis shows that parents years since immigration and education affect risks of the number of periods in persistent poverty. While a native child is very unlikely to spend nine years in poverty, the corresponding risk for a child to a newly arrived immigrant was found to be far from negligible. Much of the pattern is similar across the three countries but there are also some notable differences.

Many studies have shown that an unfavourable psychosocial environment increases the risk of mental and physical illness, as well as absenteeism, or sickness absence. However, more costly than absenteeism is presenteeism, where a person is present at work even though disabled by a mental or physical illness. We sought to identify factors explaining why workers would come to work even when their health is impaired. In a cross‐sectional design data were collected from 3825 employees of a Canadian organisation. The results show a high occurrence of presenteeism: workers went to work in spite of illness 50% of the time. Presenteeism propensity (the percentage of days worked while ill over total number of sick days) was higher for workers who were ill more often. Heavier workloads, higher skill discretion, harmonious relationships with colleagues, role conflict and precarious job status increased presenteeism, but decision authority did not. Workers reporting high psychological distress and more severe psychosomatic complaints were also more likely to report higher rates of presenteeism. These results suggest that stress research should not only include absenteeism as an outcome indicator, but also consider presenteeism.

In this chapter, the authors examine trust and social networks among entrepreneurs operating in a developing market context. At the centre of this study, trust emerges from the interplay of a range of cultural-specific factors, each of which describes how social relations shape economic action. Using case studies of exporting Nigerian small and medium sized enterprises, the authors document how exporting arrangements are enforced across West African markets. Interview data reveal how entrepreneurs take advantage of indigenous trust-based relationships to enforce exporting agreements. It is clear that exporting activities are shaped by trust and networks of kinship and market associations that permeate the West African region. This chapter facilitates a better understanding of trust and the range of indigenous relationships that underpin exporting activities in Nigeria and particularly across West Africa.
