Partners in crime? De invloed van crimineel gedrag op huwelijkskansen en partnerselectie

Summary: Partners in crime? The impact of criminal behaviour on marriage formation and partner selection. Although it is well established that marriage has the potential to foster desistance from crime, little attention has been paid to offenders’ marital chances. The few studies examining the effects of criminal behaviour on marriage formation, have not taken into account the criminal behaviour of spouses. We employ data from the Criminal Career and Life-Course Study (N = 4,615) to examine the marital and criminal careers of both offenders and their marriage partners far into adulthood. The results show that a criminal history is strongly related to outcomes in the marriage market. The higher the number of offenses, the lower the odds of marrying and the higher the odds of marrying a criminal partner

The impact of first-time imprisonment on marriage and divorce:a matched samples comparison in a Dutch conviction cohort

Marriage has a prominent place in criminological theory and research as one institution that has the potential to genuinely foster desistance from a criminal career. Mass imprisonment policies in the United States and elsewhere, therefore, pose a potential threat of increased crime if they impede the ability of ex-prisoners to reintegrate into society by stigmatizing them and limiting their chances in the marriage market. We use a long-term study of a conviction cohort in The Netherlands to ascertain the effect that first-time imprisonment has on the likelihood of marriage and divorce. The results suggest that the effect of imprisonment on the likelihood of marriage (among unmarried offenders) is largely a selection artifact, although there is very weak evidence for a short-lived impact that does not persist past the first year post-release. This is interpreted as a residual incapacitation effect. On the other hand, the results strongly suggest that the experience of incarceration leads to a substantially higher divorce risk among offenders who are married when they enter prison

The effect of warmth acclimation on behaviour, thermophysiology and perception

Public and commercial buildings tend to overheat and considerable energy is consumed by air-conditioning and ventilation. However, many occupants remain unsatisfied and consequently exhibit thermoregulatory behaviour (TRB), e.g. opening windows or controlling the air-conditioning. This, in turn, might negatively influence the building energy use. This paper hypothesizes that warmth acclimation influences thermophysiology, perception and TRB in a warm environment. Therefore, the effect of warmth acclimation on TRB, physiology and perception is investigated. Twelve participants underwent a so-called SWITCH protocol before and after warmth acclimation (7 days, 6h/day, about 33 degrees C, about 22% RH). During SWITCH, the participants chose between a warm (37 degrees C) and a cold (17 degrees C) condition. TRB was determined by the number of switches and the time spent in a specific condition. Mean skin temperature was recorded to assess behavioural thresholds. Thermal comfort and sensation were indicated on visual analogue scales (VAS). After acclimation, the upper critical behavioural threshold significantly increased from 35.2 +/- 0.6 to 35.5 +/- 0.5 degrees C (p0.05) and the range of mean skin temperatures at which no behaviour occurred significantly widened (3.6 +/- 0.7 to 4.2 +/- 0.6;
