Prevalence of Legal, Prescription, and Illegal Drugs Aiming at Cognitive Enhancement across Sociodemographic Groups in Germany
There has been speculation about a growing demand for substances used without medical need for cognitive enhancement (CE). Thus, the prevalence rates and the identification of sociodemographic groups at risk of this behavior need further description and constant monitoring. We conducted a nationwide web-based representative sample (N = 22,101) (regarding sex, age, education, and federal state) of the general adult population in Germany. Results s…
Aggressive behavior and social status
In everyday situations, violations of social norms can be perceived as provocations that trigger aggression, which can have negative consequences for the individuals involved and social coexistence. Based on the General Aggression Model (GAM), we investigate how a physical provocation affects the internal state (cognition, arousal, and affect) of the provoked person and how this then affects their potential reactions. We also investigate the mode…
Understanding change and differential updating of risk perceptions associated with illicit substance use
Neutralization strategies account for the concern-behavior gap in renewable energy usage – Evidence from panel data from Germany
Mechanisms of Perceived Social Norms
While the nonmedical use of prescription drugs to enhance cognitive performance (NMUPD-CE) has received increasing media attention and provoked ethical debates, the social drivers of misusing this health-related drug remain understudied. Therefore, this study examined how descriptive and injunctive norms as social influences affect decisions to engage in NMUPD-CE. We tested competing assumptions about whether moral acceptability and positive and …
An experimental test of Situational Action Theory of crime causation
Framing electricity plan choices to enhance green energy usage
Umweltentscheidungen als Wechselspiel von Einstellungen, Handlungskosten und situativer Rahmung – ein empirischer Theorienvergleich mit Daten des Gesis Panels
Verschiedene theoretische Ansätze versuchen, den Zusammenhang zwischen individuellen Umwelteinstellungen und umweltbezogenem Verhalten bei Alltagsentscheidungen zu erklären. Die Low-Cost-Hypothese wie auch duale Prozessmodelle im Allgemeinen und das Modell der Frame Selektion im Speziellen unterstellen dabei für das Wechselspiel von Umwelteinstellungen und Entscheidungskosten unterschiedliche Wirkungszusammenhänge. Der Beitrag möchte durch die Ei…

Wirkungen monetärer Anreize auf Antworten zur eigenen Delinquenz bei postalischer Befragung / Effects of Monetary Incentives on Self-Reports on Delinquency in a Mail Survey
Im vorliegenden Beitrag werden die Ergebnisse einer in dieser Zeitschrift erschienen Studie von Skarbek-Kozietulska, Preisendörfer & Wolter (2012) über die Validität der Antworten straffällig gewordener Befragter aufgegriffen. Die Autoren stellten einen negativen Effekt der Antwortlatenz fest, demzufolge spät Antwortende eher dazu neigen, ihre Straftaten zu leugnen. Die Gründe hierfür vermuten die Autoren in den Eigenheiten der TDM (tailored desi…
Incentives and Inhibitors of Abusing Academic Positions
In a web-based survey, we presented university students (n = 2,287) with vignettes in which they had to decide whether to abuse the position of student assistant for personal gain. Referring to the existing literature, we tested whether the emergence of corruption increases when benefits from corruption and the probability of the occurrence of those benefits rise and whether corruption decreases when costs and the probability of their occurrence …

Bei der Frage nach den Determinanten der Zustimmung zu sozialstaatlichen Maßnahmen seitens der Bevölkerung wird in der Literatur entweder auf die Werterwartungstheorie oder auf die Bedeutung ergebnisunabhängiger Wertorientierungen und Einstellungen zurückgegriffen. In dieser Arbeit werden beide Ansätze am Beispiel inter- generationaler Transferleistungen für Familien mit Kindern (Erhöhung des Kindergeldes) diskutiert und mithilfe der Entscheidung…
Explaining preferences for redistribution
Explanations of different patterns of preferences for redistribution either highlight the role of the institutional framework in a country or highlight the importance of self‐interest and rational expectations. The study introduces a unified approach to explain differences in preferences for redistributive measures for the case of intergenerational monetary transfers for families and children. Both explanatory approaches are integrated into the a…

The Interplay of Moral Norms and Instrumental Incentives in Crime Causation
Rational choice theories (RCTs) of crime assume actors behave in an instrumental, outcome‐oriented way. Accordingly, individuals should weight the costs and benefits of criminal acts with subjective probabilities that these outcomes will occur. Previous studies either do not directly test this central hypothesis or else yield inconsistent results. We show that a meaningful test can be conducted only if a broader view is adopted that takes into ac…
Modelling a rational choice theory of criminal action
Referring to classic rational choice models of criminal behaviour (Becker 1968), this paper presents an extended Subjective Expected Utility model that is more in line with the requirements of theorizing and empirical testing than former models. In our model, the decision of an actor is influenced by the expected utility of the crime and the norms that prohibit the delinquent action. It is suggested that there is an interaction between utility an…

When Anomie Becomes a Reason for Suicide
Durkheim's theory of suicide was among the first attempts within sociology to combine theoretical and empirical approaches. Empirical evidence has not yet produced cohesive results. In our opinion, this is due to inappropriate operationalization in previous studies. According to Durkheim's theory, ‘normal’ country-specific suicide levels and pathological suicide rates are different, and only the latter is really of sociological interest, as they …
Social Class and Delinquency
The frequently predicted relationship between social class and criminal behavior is theoretically vacillating and empirically exiguous. We present an extended rational choice model which integrates the effects of an individual's social status on his or her subjective evaluations of (1) costs, (2) utility, (3) the probability of apprehension, (4) the selective incentives, and (5) the internalization of social norms. We test the model against the o…

Why Nations Arm in the Age of Globalization
What accounts for different levels of military forces between countries and over time? Payne (1989) found in cross country regressions cultural influences to be the most important determinant. In contrast to Payne, we will show that the mechanisms of why nations arm can only be fully discovered by time series analysis and – going beyond Payne's model – we will test the impact of the end of the Cold War and show that the process of globalization h…

Neutralization strategies account for the concern-behavior gap in renewable energy usage – Evidence from panel data from Germany
Methodische Probleme bei der Analyse von Wertvorstellungen und Wirtschaftswachstum
Inglehart (1997) überprüft in multivariaten Regressionsanalysen den Einfluss von Leistungsbedürfnis und Postmaterialismus 1990 auf das Wirtschaftswachstum in der Periode 1960-1989 und vergleicht die Effekte mit denen ökonomischer Einflussfaktoren. Er stellt einen signifikanten positiven Effekt des Leistungsbedürfnisses fest. Ingleharts Ergebnis ist jedoch fragwürdig, da er die Ursachen (Leistungsbedürfnis und Postmaterialismus) nach der Wirkung (…
