Fear of Crime and Feelings of Unsafety in European Countries: Macro and Micro Explanations in Cross‐National Perspective

In this study, we set out to explain fear of crime and feelings of unsafety, using two waves of the European Social Survey (2006 and 2008) covering 25 European countries (N = 77,674). The results of our multilevel analyses showed varying effects of contextual‐ and individual‐level characteristics on our two outcomes. Higher crime levels in countries increase the fear of crime; however, they do not affect feelings of unsafety. Social protection expenditure proves to be an important determinant of both fear of crime and feelings of unsafety. Moreover, distrust in the police, generalized social distrust, and perceived ethnic threat induce fear of crime as well as feelings of unsafety. Finally, policy implications are discussed.     

Gay SM in pornography and reality

A picture of SM interactions as depicted by pornographical issues of SM between 1974 and 1983 is presented by means of a correlational study of pornography. Actual SM scenarios are then compared with the depiction in magazines. The changes that have occurred over more than a decade reflected changes in the nature of violence and sexuality.     

Contextual Effects on Surprise Expressions: A Developmental Study

Although research succeeds in eliciting spontaneous feelings of surprise with participants, these participants rarely show a prototypical expression of raising eyebrows, opening mouth, and widening eyes. In other words, there seems to be a discrepancy between the display and feeling of surprise. To get a better understanding of this discrepancy, we assessed what factors influence the display of surprise in children (study 1) and adults (study 2). In both studies, we conducted a quiz-like experiment, in which we manipulated the social context (participants either competed or collaborated), and various quiz questions to extract reactions of surprise (either caused by unexpectedly correct or unexpectedly incorrect answers). Results show that cause and social context did not affect the appearance of specific features in participants’ surprise display. However, we did find these factors to interact with regards to the intensity of perceived surprise displays of adults. For children, these relations were less complex. Overall, we can conclude that the expression of surprise is indeed moderated by contextual factors, namely cause of the surprise, social context, and age.     

Day Labourers' Work Related Injuries: An Assessment of Risks,Choices, and Policies

Literature and theory surrounding the informal economy in international contexts suggest that informal work arrangements may entail assuming various levels of risk, and that the higher the level of risk in an employment arrangement, the higher the premium paid to the worker. This study is designed to assess if a wage compensation for risk exists within the United States' day labour job market ‐ the most visible sector of the United States' informal economy. Using data from the 2005 National Day Labour Survey we find a statistically significant wage premium indicating that a risk‐wage tradeoff within the day labour informal economy exists. Ultimately, we argue that current policy interventions facilitated through day labour centres into the day labour market appear to be effective in mitigating the risks associated with this type of employment.

• Evidence of a risk‐wage premium in the day labour market suggests there is an incentive to assume higher levels of risk in work arrangements which presents significant concerns for worker safety.
• Higher levels of work related risks assumed by day labourers, may be minimized if they receive proper safety training through a formal venue such as a worker centre.
• Worker centres only serve 20 per cent of all day labourers in the United States, suggesting a need for the establishment of additional worker centres in other connected or industry based work sites, to help mitigate potential work related risks and injuries in the day labour market.

     

The evaluation of team lifting on physical work demands and workload in ironworkers

Lifting and carrying heavy loads occur frequently among ironworkers and result in high prevalence and incidence rates of low back complaints, injuries and work-disability. From a health perspective, little information is available on the effect of team lifting on work demands and workload. Therefore, the objective of this study was to compare the effects of team lifting of maximally 50 kg by two ironworkers (T50) with team lifting of maximally 100 kg by four ironworkers (T100). This study combined a field and laboratory study with the following outcome measures: duration and frequency of tasks and activities, energetic workload, perceived discomfort and maximal compression forces (Fc peak) on the low back. The physical work demands and workload of an individual iron worker during manual handling of rebar materials of 100 kg with four workers did not differ from the manual handling of rebar materials of 50 kg with two workers, with the exception of low back discomfort and Fc peak. The biomechanical workload of the low back exceeded for both T50 and T100 the NIOSH threshold limit of 3400N. Therefore, mechanical transport or other effective design solutions should be considered to reduce the biomechanical workload of the low back and the accompanying health risks among iron workers.     

Does team lifting increase the variability in peak lumbar compression in ironworkers?

Ironworkers frequently perform heavy lifting tasks in teams of two or four workers. Team lifting could potentially lead to a higher variation in peak lumbar compression forces than lifts performed by one worker, resulting in higher maximal peak lumbar compression forces. This study compared single-worker lifts (25-kg, iron bar) to two-worker lifts (50-kg, two iron bars) and to four-worker lifts (100-kg, iron lattice). Inverse dynamics was used to calculate peak lumbar compression forces. To assess the variability in peak lumbar loading, all three lifting tasks were performed six times. Results showed that the variability in peak lumbar loading was somewhat higher in the team lifts compared to the single-worker lifts. However, despite this increased variability, team lifts did not result in larger maximum peak lumbar compression forces. Therefore, it was concluded that, from a biomechanical point of view, team lifting does not result in an additional risk for low back complaints in ironworkers.     

A Non-stationary Cox Model

The purpose of this paper is to consider the problem of statistical inference about a hazard rate function that is specified as the product of a parametric regression part and a non-parametric baseline hazard. Unlike Cox's proportional hazard model, the baseline hazard not only depends on the duration variable, but also on the starting date of the phenomenon of interest. We propose a new estimator of the regression parameter which allows for non-stationarity in the hazard rate. We show that it is asymptotically normal at root- n and that its asymptotic variance attains the information bound for estimation of the regression coefficient. We also consider an estimator of the integrated baseline hazard, and determine its asymptotic properties. The finite sample performance of our estimators are studied.     

Real‐world scene perception in infants: What factors guide attention allocation?

The foci of visual attention were modeled as a function of perceptual salience, adult fixation locations, and attentional control mechanisms (measured in separate tasks) in infants (N = 45, 3‐ to 15‐month‐olds) as they viewed static real‐world scenes. After controlling for the center bias, the results showed that low‐level perceptual salience predicts where infants look. In addition, high‐level factors also played a role: Infants fixated parts of the scenes frequently fixated by adults and this effect was stronger for older than younger infants. In line with this finding, infant fixation durations were longer on regions more frequently fixated by adults, implying longer time taken to process the available information. Fixation durations decreased with age, and this decline interacted with orienting skills such that fixation durations decreased faster with age for infants with high orienting skills, relative to infants with low orienting skills. There was a further interaction between fixation durations and selective attention abilities: Infants with low selective attention skills showed a decrease in fixation durations with age, whereas infants with higher selective attention skills showed a slight increase in fixation durations with age. These findings imply that infants' visual processing of static real‐world stimuli develops in accord with attentional control.     

Levels of urbanization in the world’s countries: testing consistency of estimates based on national definitions

Estimates of urbanization levels for all countries, as published in the United Nations World Urbanization Prospects, are not comparable across countries because they are based on national definitions of urbanization, which vary greatly across countries. We construct alternative estimates of urbanization that are comparable across countries, to use these estimates to point out definitional problems or outlying countries with interesting urban characteristics. The alternative estimates are constructed using variables that are associated with urbanization, as well as a categorical variable that summarizes the urban definition used in the country. We find that among the 181 countries included in the analysis, 21 % have a restrictive definition, and 31 % a generous definition of urbanization. In 2000, the difference between the alternative estimate and the UN estimate was more than 10 % for 67 countries. An examination of six countries with surprisingly low or high reported levels of urbanization, as compared the alternative estimates, highlights issues with the plausibility of the official estimate. We conclude that comparison of urbanization estimates across countries should be treated with care, given the wide range of definitions used. To produce more informative estimates of urbanization, several countries would need to clarify or rethink their definition of urban.
