How to survey displaced workers in Switzerland ? Sources of bias and ways around them

Studying career outcomes after job loss is challenging because individually displaced worker form a self-selected group. Indeed, the same factors causing the workers to lose their jobs, such as lack of motivation, may also reduce their re-employment prospects. Using data from plant closures where all workers were displaced irrespective of their individual characteristics offers a way around this selection bias. There is no systematic data collection on workers displaced by plant closure in Switzerland. Accordingly, we conducted our own survey on 1200 manufacturing workers who had lost their job 2 years earlier. The analysis of observational data gives rise to a set of methodological challenges, in particular nonresponse bias. Our survey addressed this issue by mixing data collection modes and repeating contact attempts. In addition, we combined the survey data with data from the public unemployment register to examine the extent of nonresponse bias. Our analysis suggests that some of our adjustments helped to reduce bias. Repeated contact attempts increased the response rate, but did not reduce nonresponse bias. In contrast, using telephone interviews in addition to paper questionnaires helped to substantially improve the participation of typically underrepresented subgroups. However, the survey respondents still differ from nonrespondents in terms of age, education and occupation. Interestingly, these differences have no significant impact on the substantial conclusion about displaced workers' re-employment prospects

Evaluating the drivers of and obstacles to the willingness to use cognitive enhancement drugs: the influence of drug characteristics, social environment, and personal characteristics

Sattler S, Mehlkop G, Graeff P, Sauer C. Evaluating the drivers of and obstacles to the willingness to use cognitive enhancement drugs: the influence of drug characteristics, social environment, and personal characteristics. Substance Abuse Treatment, Prevention, and Policy. 2014;9(1): 8.Background The use of cognitive enhancement (CE) by means of pharmaceutical agents has been the subject of intense debate both among scientists and in the media. This study investigates several drivers of and obstacles to the willingness to use prescription drugs non-medically for augmenting brain capacity. Methods We conducted a web-based study among 2,877 students from randomly selected disciplines at German universities. Using a factorial survey, respondents expressed their willingness to take various hypothetical CE-drugs; the drugs were described by five experimentally varied characteristics and the social environment by three varied characteristics. Personal characteristics and demographic controls were also measured. Results We found that 65.3% of the respondents staunchly refused to use CE-drugs. The results of a multivariate negative binomial regression indicated that respondents’ willingness to use CE-drugs increased if the potential drugs promised a significant augmentation of mental capacity and a high probability of achieving this augmentation. Willingness decreased when there was a high probability of side effects and a high price. Prevalent CE-drug use among peers increased willingness, whereas a social environment that strongly disapproved of these drugs decreased it. Regarding the respondents’ characteristics, pronounced academic procrastination, high cognitive test anxiety, low intrinsic motivation, low internalization of social norms against CE-drug use, and past experiences with CE-drugs increased willingness. The potential severity of side effects, social recommendations about using CE-drugs, risk preferences, and competencies had no measured effects upon willingness. Conclusions These findings contribute to understanding factors that influence the willingness to use CE-drugs. They support the assumption of instrumental drug use and may contribute to the development of prevention, policy, and educational strategies

Der illegale Verkauf verschreibungspflichtiger Medikamente zur kognitiven Leistungssteigerung: Eine vignetten-basierte Studie rationaler und normativer Erklärungsgründe [The illegal sale of prescription drugs for enhancing cognitive performance: A vignette-based study of rational and normative causes]

Item does not contain fulltextThe illicit sale of prescription drugs for enhancing cognitive performance is a criminal act which has hardly been studied although the consumption of these drugs by healthy people has numerous negative individual and social consequences. In this study, we scrutinize the decision to sale those drugs based on assumptions of various criminological rational choice models, self-control theory, social norms, as well as the Model of Frame Selection (MFS) and the Situational Action Theory (SAT). Thereby, we also consider interactions between instrumental incentives, self-control and norms. To investigate decisions regarding the illegal sale of performance enhancing drugs, we used a web-based survey among students at four German universities (N=1,698). Each respondent received randomly one out of 900 vignettes, in each case describing a hypothetical sales situation concerning the illegal and financially rewarding transmission of medications to enhance concentration between students. The descriptions have been randomly varied with respect to the sales profits and the severity of punishments and their respective probabilities. Moreover, the degree of self-control and internalized norms regarding illegal sales have been assessed. The results, that are derived from double hurdle models, show that, especially, internalized norms as well as the severity of punishment reduce the willingness of selling, while low self-control and increasing profits increase this willingness. In addition, a negative interaction effect between low self-control and the severity of punishment shows that a more severe punishment leads to more deterrence when self-control is lower (respectively that with more sever punishments, the impact of self-control decreases). Although the results support the theoretical assumptions only partially, we can show that internalized norms significantly influence the perception of criminal behavior while the benefits of such behavior and self-control seem to operate in a downstream deliberation process.28 p

The Rationale for Consuming Cognitive Enhancement Drugs in University Students and Teachers

Sattler S, Sauer C, Mehlkop G, Graeff P. The Rationale for Consuming Cognitive Enhancement Drugs in University Students and Teachers. PLoS ONE. 2013;8(7): e68821.Cognitive enhancement (CE) is the pharmaceutical augmentation of mental abilities (e.g., learning or memory) without medical necessity. This topic has recently attracted widespread attention in scientific and social circles. However, knowledge regarding the mechanisms that underlie the decision to use CE medication is limited. To analyze these decisions, we used data from two online surveys of randomly sampled university teachers (N = 1,406) and students (N = 3,486). Each respondent evaluated one randomly selected vignette with regard to a hypothetical CE drug. We experimentally varied the characteristics of the drugs among vignettes and distributed them among respondents. In addition, the respondent’s internalization of social norms with respect to CE drug use was measured. Our results revealed that students were more willing to enhance cognitive performance via drugs than university teachers, although the overall willingness was low. The probability of side effects and their strength reduced the willingness to use CE drugs among students and university teachers, whereas higher likelihoods and magnitudes of CE increased this propensity. In addition, the internalized norm against CE drug use influenced decision making: Higher internalization decreased the willingness to use such medications. Students’ internalized norms more strongly affected CE abstinence compared with those of university teachers. Furthermore, internalized norms negatively interacted with the instrumental incentives for taking CE medication. This internalization limited the influence of and deliberation on instrumental incentives. This study is the first to provide empirical evidence regarding the importance of social norms and their influence on rational decision making with regard to CE. We identified previously undiscovered decision-making patterns concerning CE. Thus, this study provides insight into the motivators and inhibitors of CE drug use. These findings have implications for contending with CE behavior by highlighting the magnitude of potential side effects and by informing the debate regarding the ethics of CE use

Population ageing, the intergenerational conflict, and active ageing policies - a multilevel study of 27 European countries

In the scientific and the public debate demographic ageing is sometimes perceived as an unstoppable “grey tide” which will inevitably lead to a conflict between the old and young generation. In this paper we empirically evaluate whether we find any evidence for an intergenerational conflict in Europe and which factors might influence its severity. In particular, we answer the following questions. (1) Is there a conflict between the interests of the younger and the older generation? (2) Does the strength of the conflict increase with population ageing? And finally, (3) can a policy of Active Ageing, i.e. better integrating older generations into society, moderate the conflict? We answer these questions in a comparative study of 27 European countries using data from the Eurobarometer 2009. Our results show a moderate conflict between generations. Compared to spending preferences of the younger generation, older people are more likely to support increased spending for old age at the expense of educational spending. Contrary to expectation, generational conflict does not increase with population ageing. Linking country differences in the strength of the generational conflict to the degree of population ageing with multilevel regression techniques we do not find any evidence that the conflict is increasing In a final step of our analysis we evaluate the potential of generational policies - measured with the Active Aging Index - to mitigate the generational conflict. Intergenerational conflict is weaker when older people actively participate in the political life and are visible in society, suggesting Active Aging policies as a means to mitigate intergenerational conflict
