This study extends experimental tests of (cumulative) prospect theory (PT) over prospects with more than three outcomes and tests second-order stochastic dominance principles (Levy and Levy, Management Science 48:1334–1349, 2002; Baucells and Heukamp, Management Science 52:1409–1423, 2006). It considers choice behavior of people facing prospects of three different types: gain prospects (losing is not possible), loss prospects (gaining is not possible), and mixed prospects (both gaining and losing are possible). The data supports the distinction of risk behavior (...) into these three categories of prospects, Further, probability weighting and diminishing sensitivity of utility as predicted by PT are observed. Loss aversion is, however, less pronounced, except for choices where one prospect is degenerate. The data suggests that the probability of losing may be relevant for loss aversion. (shrink)

Introducción: El embarazo, aborto, las infecciones de transmisión sexual incluido el Virus de Inmuno Deficiencia Humana, se han convertido en problemas sanitarios de mayor vulnerabilidad en jóvenes. Objetivo: Describir las conductas de riesgo y prevalencia de problemas sexuales y reproductivos de estudiantes universitarios. Método: Investigación descriptiva, el universo estuvo constituido por alumnos de dos grupos de segundo semestre; el grupo de estudio conformado por la totalidad de estudiantes de la Facultad de Salud Pública ; y el control seleccionado mediante una (...) muestra aleatoria de estudiantes del resto de las facultades, se realizó esta selección con el propósito de valorar la homogeneidad de las variables entre los grupos. Resultados: Existe homogeneidad en la mayoría de conductas de riesgo y problemas sexuales en los grupos, en consecuencia estas variables no están influenciadas por la pertenencia a la Facultad de Salud Pública. Se evidencian conductas de riesgo como: inicio temprano de relaciones sexuales, múltiples parejas, infidelidad, relaciones sexuales ligadas al consumo de sustancias, dificultades con el uso de métodos anticonceptivos o de protección; se encontró prevalencia de problemas como: experiencia de embarazos, la mayoría no planeados, abortos inducidos y presencia de infecciones de transmisión sexual. Conclusiones: Existe vulnerabilidad en la salud sexual y reproductiva de los jóvenes universitarios independientemente de la formación que reciben, por tanto, emerge la necesidad de buscar alternativas integrales de promoción, prevención y educación sexual integral. Introduction: Pregnancy, abortion, sexually transmitted infections including Human Immunodeficiency Virus, have become a health problem of more vulnerable in young people. Objective: To describe risk behaviors and prevalence of sexual and reproductive problems of university. Method: Descriptive study, the universe consisted of students from two groups of second semester; the study group is conformed by students of the Public Health Faculty ; and control selected by a random sample of students from other faculties, in order to assess the homogeneity of the variables between groups. Results: Homogeneity exists in most risk behaviors and sexual problems in groups, therefore these variables are not influenced by membership in the Public Health Faculty. Risk behaviors as evidence: early initiation of sexual activity, multiple partners, infidelity, sexual relationship linked to substance consumption, which prevails alcohol, together with the non-use or inappropriate use of contraception or protection; experience of pregnancy, most unplanned, induced abortions and the presence of sexually transmitted infections: prevalence of problems as found. Conclusions: There is vulnerability in sexual and reproductive health of young students regardless of their training, thus emerges the need to find alternatives comprehensive promotion, prevention and comprehensive sex education.

Studies of mediation practices typically focus on parental mediation, but during adolescence parents’ impact decreases relative to that of peers. This study compares perceived parental and peer mediation in the context of media portrayals of risk behavior and adolescents’ perceptions thereof. A cross-sectional survey was conducted among 278 adolescents aged 12 to 17 (M = 14.18, SD = 1.62, 51.4 % girls) using Hayes’s process macro (model 4) to investigate direct and indirect associations between mediation, media-related cognitions, and (...) social norms. Findings indicate that perceived parental and peer mediation are related to adolescents’ media-related cognitions and perceived social norms in equally important but different ways. (shrink)

Criminal law is one of the regulatory tools being used in the United States to influence risk behavior by people who have HIV/AIDS. Several different types of laws have been or could be used in this way These include:HIV-specific exposure and transmission laws — i.e., laws that explicitly mention and exclusively apply to conduct by people with HIV;public health statutes prohibiting conduct that would expose others to communicable diseases and/or sexually transmitted diseases ; andgeneral criminal laws governing attempted (...) murder and assault.

The aim of this study was to validate the Polish adaptation of the Treatment Self-Regulation Questionnaire, which measures the degree of self-determination in risk behaviour changes. The study comprised 219 patients, beginning to undergo treatment. The Global Motivation Scale was used to test a convergent validity. The confirmatory factor analysis did not support the theoretical four-factor model, thus an exploratory analysis was conducted to determine an optimal model across risk behaviours. The adopted two-factor model matched original TSRQ subscales: (...) autonomous motivation and external regulation. The internal consistency of factors ranging from.78 to.89. Structural equation modeling revealed the impact of global motivation on contextual motivation, limited to the equivalent type of regulation. The action aimed at supporting patient’s autonomy should consider the particular behaviour and the global motivation as a resource in disease. (shrink)

This paper studies whether incentivizing performance with competition and cooperation-based incentive schemes, rather than individual compensation, affects peer effects on subsequent risk behaviour. We run a laboratory experiment in which we introduce three different compensation schemes—piece rate, the equal-split-sharing-rule and a tournament—associated with a real effort task and we measure risk behaviour both before and after the effort task. We find that competition more than halves peer influence on risk behaviour compared with piece-rate compensation and in some (...) specifications produces negative peer effects. Competition also significantly reduces an individual’s feeling of attachment to their peers and self-reported peer influence. (shrink)

The aim of the present study was to carry out a qualitative and quantitative synthesis of the existing literature studying the relationship between emotional intelligence and risk behavior. We conducted a systematic review and meta-analysis of the scientific evidence available relating both constructs. Particular attention was paid to identifying possible differences in this relationship as a function of the different conceptualizations of EI and the risk domain. The study was conducted following the Cochrane and PRISMA guidelines. Our (...) results revealed a significant negative relationship between EI and health-related risk behaviors. However, this relationship was not observed in other risk domains such as finance and gambling. The relationship between EI and risk behavior differed according to the risk domain studied, which supports the notion that risk is a domain-specific construct. The results associated with the health-related risk behaviors are consistent with existing literature about the positive impact of emotional abilities on the health domain. A more complete understanding of the emotional mechanisms that underlie risk behavior could help to establish action guidelines and improve programmes to prevent and reduce the negative effects of risk behavior on our society.

This paper examines the importance of aspirations as reference points in a multi-period decision-making context. After stating their personal aspiration level, 172 individuals made six sequential decisions among risky prospects as part of a choice experiment. The results show that individuals make different risky-choices in a multi-period compared to a single-period setting. In particular, individuals’ aspiration level is their main reference point during the early stages of decision-making, while their starting status (wealth level at the start of the experiment) becomes (...) the central reference point during the later stages of their multi-period decision-making.

The development of collective beliefs via informational and reputational cascades represents a way of shortcircuiting the difficulties related to the collective action of ‘latent groups’ to ensure the promotion of their particular interests. This essay focuses on the protection of consumers, whose quality of the life has never been so high, despite the prevalence of hazardous products.Rationally ignorant individuals form their opinions by conforming to those of others; this can take two forms, either by consolidating their personal judgement or their (...) private information, or by pure conformist behaviour. It may even be that such individuals rarely hesitate, if necessary, to admit beliefs that they do not actually hold in order to avoid being ostracised by others. ‘Latent groups’ activists manipulate the process of formation of beliefs in order to bring about a predominant opinion on any given issue. Armed with the asset of the prevailing opinion, pressure can be exerted upon politicians in view of obtaining regulations and subsidies which would protect the ‘latent group’ of which they claim to be the representatives.This is the new face of collective action where the “politically correct” replaces physical violence or the strike. This way of shaping public opinion could have a beneficial outcome if it were not founded on erroneous information or led to a violation of individual rights due to regulation. However, this not the case. The very leitmotif of this method is, in fact, to bring about regulation which, by definition, violates private lives. In any case, it is dangerous because the manipulation of public opinion by these activists implies an intensive use of rhetoric, distorting the perception of risk, which in turn involves the circulation of misleading information in order to create a cascade modifying public opinion in favor of the proposed regulation, rather than informing the public on the potential risks and letting them insure freely against it if they judge to do so. But for the activist the end justifies the means. Thus, this manipulation of public opinion is a danger to the notion of modern democracy, already so sensitive to the pertaining to the majority.La formation des croyances par le biais des cascades d’information et de réputation est un moyen de courtcircuiter les difficultés liées à l’action collective des groupes latents pour assurer la promotion de leurs intérêts particuliers. Dans le cadre de cet essai est analysée la protection des consommateurs, dont la valeur de la vie est élevée, contre les produits à risque.Les individus rationnellement ignorants forment leurs opinions en se conformant aux croyances des autres, soit pour conforter leur jugement personnel ou leurs informations privées, soit par conformisme pur. Il se peut même que les individus n’hésitent pas, s’il le faut, à afficher de fausses croyances, pour ne pas être frappés d’ostracisme par les autres.Les activistes des “groupes latents” manipulent le processus de formation des croyances pour faire émerger une opinion majoritaire sur un problème spécifique. Grâce à cette opinion majoritaire ils vont pouvoir faire pression auprès des hommes politiques pour obtenir une réglementation et des subventions à leur propre profit dans le but de protéger le “groupe latent” dont ils prétendent être les représentants. Ce sont les nouvelles formes d’action collective où le politiquement correct remplace la violence physique ou le piquet de grève.Cette façon de former l’opinion publique pourrait avoir des conséquences bénéfiques si elle n’était pas fondée sur des informations erronées et si elle n’aboutissait pas à une violation des droits individuels par la réglementation. Or ce n’est pas le cas. Elle est faite justement pour faire émerger une réglementation qui par définition viole la vie privée des gens. Par ailleurs, elle est dangereuse parce que la manipulation de l’opinion publique par ces activistes implique un usage intensif de figures de rhétorique, de biais dans la perception des risques, de diffusion de fausses informations dans le but d’enclencher une cascade qui va modifier l’opinion publique en faveur de la réglementation et non pas dans le but d’éclairer le public sur les véritables risques encourus, la fin justifiant les moyens.Cette manipulation des croyances est alors un danger pour la démocratie politique contemporaine déjà si sensible à l’opinion majoritaire.

BackgroundPrevious studies have focused on the opposite relation between muscle strength, obesity, and depression in adults. Moreover, the evidence has indicated that obesity and depression in adults might be significantly decreased with Muscle Strength Exercise albeit it might be insufficient. Therefore, the current study aimed to investigate the association between MSE, adiposity, and depression among United States adolescents.Materials and methodsThis cross-sectional study used the Youth Risk Behavioral Survey data. In YRBS, a cluster sample was used, and the investigation was (...) divided into three stages. The study surveyed 13,677 high school students and conducted self-reported questionnaires on sex, grade, race/ethnicity, MSE days, overweight, obesity, and depressive symptoms. The study got the nationally representative population of American students in Grade 9 to 12.ResultsA total of 13,677 participants were included in the final analysis. The participants meeting the guidelines’ requirements seemed more likely to be obese than those not meeting. There was no statistical significance in the relations between the MSE guidelines and overweight and depression. For all the participants, the prevalence of those conforming to MSE was 30.1%. One-fifth of the participants reported no MSE per week, 7.8% reported 3 days of MSE per week, and 7.7% reported 7 days.ConclusionThe main finding of this study indicated a positive relationship between the normative MSE required in guidelines and low-level obesity. Beyond that, the evidence was insufficient to confirm the positive links between MSE and depression among American adolescents. Our study could offer evidence for future MSE interventions in adolescents. (shrink)

Experiments on intertemporal consumption typically show that people have difficulties in optimally solving such problems. Previous studies have focused on contexts in which agents are faced with risky future incomes and have to plan over long horizons. We present an experiment comparing decision making under certainty, risk, and ambiguity, over a shorter lifecycle. Results show that behavior in the ambiguity treatment is markedly different than in the risk condition and it is characterized by a significant pattern of (...) under-consumption. (shrink)

As a result of the devastating health effects of the COVID-19 outbreak, the lockdown has been considered a safety measure in many countries. In Pakistan, the first case of COVID-19 was reported in February 2020. The purpose of this qualitative study was to investigate people’s risk perception and protective behavior during the lockdown. Twenty-two (22) participants from eight big cities across Pakistan were interviewed. A six-step reflective thematic analysis was used for data analysis. The study focused on (...) class='Hi'>risk perception and protective behaviors. Our main analytical goal was to understand how risk perception shapes human behavior in the context of lockdown, pandemic-related information flow, and corresponding meaning-making. The study revealed that people influenced by information and advice campaigns form a perception of risk that has shaped their protective behavior. They used familiar means of coping with distress, including the search for strength through religious belief practices and following the precautions recommended by health professionals through the media.

There is limited knowledge of the prevalence and nature of risky sexual behavior (RSB) among young adults in Hong Kong. This cross-sectional study explored the psychosocial risk factors of RSB with a sample of 1,171 Hong Kong university students (aged 18–40 years). Grounded in the theoretical propositions of several criminological theories (i.e., the theories of self-control, general strain, social learning, social control, and routine activity), engagement in three types of RSB (i.e., general, penetrative, and non-penetrative) was studied alongside (...) a range of psychosocial risk factors. Relative to female participants, male participants reported significantly higher mean levels of general, penetrative, and non-penetrative RSB. Male participants also reported significantly higher mean levels of negative temperament, use of alcohol and other drugs, and paraphilic interests than female participants, who reported significantly higher mean levels of self-control and social bonds than their male counterparts. The results of multivariate analyses (i.e., OLS regressions) revealed that, to a large extent, the male and female participants shared a similar set of psychosocial risk factors (i.e., use of alcohol and other drugs, and paraphilic interest) for their involvement in general, penetrative, and non-penetrative RSB. Furthermore, a high level of negative temperament was significantly associated with penetrative RSB for both genders, while a high level of perceived neighborhood disorganization was found to be an important factor in the participation of females in general, penetrative, and non-penetrative RSB. The findings of this study may have important implications for practice in regard to reducing, if not entirely preventing, the tendency to engage in RSB. (shrink)

As the frequency of internet-based research has increased, it is important for researchers to consider how the conditions in which data are collected may influence the risks to participants. In particular, because internet-based data collection often occurs outside a clinical or research setting, there may be unintentional disclosures of a participant's involvement in a research study of which the researcher is unaware. The current analysis examined the responses of men who have sex with men participating in an internet-based HIV behavioural (...) risk study when queried about the possible disclosure of their participation in the study. Fewer than 2% of participants indicated that their participation in the research study was disclosed, and all but one indicated no negative outcomes associated with the disclosure. As the field of online research continues to expand, it is important to consider risks that are unique to internet-based research, and to monitor these risks to ensure that the confidentiality of research subjects is maintained.

In the presence of incomplete risk attitudes, choices between noncomparable risky prospects are random. A random choice model advanced by Karni, 2021) includes the hypothesis that choices among noncomparable risky prospects are prompted by signals drawn from personal distributions. This paper introduces a scheme designed to elicit subjects’ assessments of their personal likelihoods of choices among noncomparable risky prospects and describes experiments designed to test the aforementioned hypothesis.

This paper studies the effects of social comparison on risk taking behavior. In our theoretical framework, decision makers evaluate the consequences of their choices relative to both their own and their peers’ conditions. We test experimentally whether the position in the social ranking affects risk attitudes. Subjects interact in a simulated workplace environment where they perform a work task, receive possibly different wages, and then undertake a risky decision that may produce an extra gain. We find that (...) social comparison matters for risk attitudes. Subjects are more risk averse in the presence of small social gain than social loss. In addition, risk aversion is decreasing in the size of the social gain. (shrink)

The present study assessed the degree to which probabilistic reasoning performance and thinking style influenced perception of risk and self-reported levels of terrorism-related behaviour change. A sample of 263 respondents, recruited via convenience sampling, completed a series of measures comprising probabilistic reasoning tasks (perception of randomness, base rate, probability, and conjunction fallacy), the Reality Testing subscale of the Inventory of Personality Organization (IPO-RT), the Domain-Specific Risk-Taking Scale, and a terrorism-related behaviour change scale. Structural equation modelling examined three progressive (...) models. Firstly, the Independence Model assumed that probabilistic reasoning, perception of risk and reality testing independently predicted terrorism-related behaviour change. Secondly, the Mediation Model supposed that probabilistic reasoning and reality testing correlated, and indirectly predicted terrorism-related behaviour change through perception of risk. Lastly, the Dual-Influence Model proposed that probabilistic reasoning indirectly predicted terrorism-related behaviour change via perception of risk, independent of reality testing. Results indicated that performance on probabilistic reasoning tasks most strongly predicted perception of risk, and preference for an intuitive thinking style (measured by the IPO-RT) best explained terrorism-related behaviour change. The combination of perception of risk with probabilistic reasoning ability in the Dual-Influence Model enhanced the predictive power of the analytical-rational route, with conjunction fallacy having a significant indirect effect on terrorism-related behaviour change via perception of risk. The Dual-Influence Model possessed superior fit and reported similar predictive relations between intuitive-experiential and analytical-rational routes and terrorism-related behaviour change. The discussion critically examines these findings in relation to dual-processing frameworks. This includes considering the limitations of current operationalisations and recommendations for future research that align outcomes and subsequent work more closely to specific dual-process models.

This article analyzes the conditions under which any change in a multiplicative background risk induces a more cautious behavior. We give necessary and sufficient conditions under which any change in the multiplicative background risk with respect to the Nth-degree stochastic dominance raises local risk aversion. Surprisingly, decreasing relative risk aversion of any order up to N in the sense of Pratt coupled with decreasing relative risk aversion in the sense of Ross are sufficient to (...) guarantee an increase in local risk aversion after any deterioration of the multiplicative background risk thanks to the Nth-degree stochastic dominance. We link our results concerning second-order stochastic dominance with the concept of multiplicative risk vulnerability. (shrink)

We examine the implications of the US government’s too-big-to-fail policy as it has been applied to banks. Using alternative measures of risk, we compare the risk-taking behavior of 11 TBTF banks, identified by the Comptroller of the Currency in 1984, to a number of non-TBTF banks. We provide both theory and new empirical evidence to support our argument that the TBTF policy leads management to significantly increase risk-taking, with no corresponding increase in performance. While prior studies (...) have considered the effects of the TBTF policy on limited, but risk-related aspects of bank behavior, such as the cost of funds, our study provides direct evidence about the risk-taking behavior associated with the TBTF policy. Our study has important implications for the current political debate regarding the too-big-to-fail policy. (shrink)

Risk-taking behavior is particularly widespread during adolescence, and negatively impacts the healthy growth and social adaptation of adolescents. Utilizing problem-behavior theory and the family stress model, the current study examined the relationship between socioeconomic status and adolescents’ risk-taking behavior, as well as the mediating role of psychological capital and self-control. A total of 1,156 Chinese adolescent students completed a series of questionnaires anonymously. The results showed that: Socioeconomic status was negatively correlated with adolescents’ risk-taking (...) behavior; Both psychological capital and self-control mediated the relationship between SES and adolescents’ risk-taking behavior independently; and Psychological capital and self-control also mediated the relationship between SES and the risk-taking behavior of adolescents sequentially. This study reveals the internal mechanism of risk-taking behavior during adolescence and provides theoretical support and empirical evidence for preventing and reducing such behavior in this age group.

Attention deficit/hyperactivity disorder (ADHD) has been linked to higher engagement in sexual risk-taking behavior (SRTB). The current study aims to establish the link between ADHD symptoms and SRTB in the general population and to examine whether an exaggerated perceived benefit of the positive outcomes of SRTB explains that link. A scale for measuring the frequency, likelihood, perceived benefit, and perceived risk of SRTB was developed. Young adult sexually active participants who did not have a stable partnership completed (...) the above scale, as well as a scale of ADHD symptoms. Level of ADHD symptoms positively correlated with the frequency and likelihood of SRTB, even when the overall level of sexual behavior was controlled for. ADHD symptoms also correlated with the perceived benefit of SRTB, but not with the perceived risk of SRTB. Mediation analysis confirmed an indirect pathway: ADHD symptoms predicted perceived benefit of SRTB, which in turn predicted increased likelihood to engage in SRTB. These findings suggest a positive link between ADHD symptoms and SRTB in the general population, which is accounted for by an exaggerated perceived benefit of SRTB. (shrink)

Unethical pro-organisational behaviour is an ongoing concern, prompting the need for more nuanced understanding of the workplace environment most likely to inhibit it. This study considers the role of risk climate, sometimes referred to as risk culture, as well as ethical climate, for reducing UPB. The study investigates whether four risk climate factors can, by focusing on the long-term consequences of UPB to the organisation, and providing guidance on behavioural norms, reduce UPB misconduct. Surveying employees in three (...) financial institutions we found that only one of the risk climate factors, avoidance, is consistently associated with UPB. On the other hand, a self-interested, ethical climate significantly increases UPB in all samples. In multi-climate analysis, we found that risk climate factors interacted with ethical climate to predict UPB. That is, when employees perceive that the workplace ethos is not self-interested, three factors of risk climate—avoidance, proactive and manager—significantly predict UPB. UPB is least likely when self-interest is low, avoidance risk climate is low, proactive risk climate is high and manager risk climate is high. Implications for leaders are discussed. (shrink)

Purpose This study aims to ascertain the impact of data collecting awareness on perceived information security concerns and information-sharing behavior on social networking sites. Design/methodology/approach Based on communication privacy management theory, the study forecasted the relationship between information-sharing behavior and awareness of data collecting purposes, data collection tactics and perceived security risk using structural equation modeling analysis and one-way ANOVA. The sample size of 521 young social media users in Vietnam, ages 18 to 34, was made up (...) of 26.7% men and 73.3% women. When constructing the questionnaire survey method with lone source respondents, the individual’s unique awareness and experiences with using online social networks (OSNs) were taken into account. Findings The results of the investigation demonstrate a significant relationship between information-sharing and awareness of data collecting, perceptions of information security threats and behavior. Social media users have used OSN privacy settings and paid attention to the sharing restriction because they are concerned about data harvesting. Research limitations/implications This study was conducted among young Vietnamese social media users, reflecting specific characteristics prevalent in the Vietnamese environment, and hence may be invalid in other nations’ circumstances. Practical implications Social media platform providers should improve user connectivity by implementing transparent privacy policies that allow users to choose how their data are used; have clear privacy statements and specific policies governing the use of social media users’ data that respect users’ consent to use their data; and thoroughly communicate how they collect and use user data while promptly detecting any potential vulnerabilities within their systems. Originality/value The authors ascertain that the material presented in this manuscript will not infringe upon any statutory copyright and that the manuscript will not be submitted elsewhere while under Journal of Information, Communication and Ethics in Society review.

SummaryThe variability of three behavioural risk factors for heart disease—heavy alcohol and tobacco consumption and physical inactivity—was assessed in an Australian Aboriginal community, where heart disease death rates were high. Prevalence levels were assessed by comparison with those experienced by all adult Australians and by evaluating whether Aboriginal rates were influenced by underlying sociodemographic conditions. Relative risk ratios, odds ratios and logistic regression analysis were used.A total of 159 males and 114 females participated. Compared to all Australians, Aborigines (...) are significantly more likely to drink five or more drinks on a drinking day, to be current smokers, and not to participate in vigorous exercise. In the Aboriginal community, univariate analysis indicates that: the odds of being a heavy drinker are significantly higher for those in unsatisfactory health; odds of being a current smoker are significantly higher for those in unsatisfactory health or unemployed; odds of not participating in vigorous exercise are significantly higher for those in unsatisfactory health, unemployed or without secondary education. Multivariate analysis shows that risk of being a heavy drinker is independently associated with sex, age, and health status; risk of being a current smoker is associated with health and employment status. The risk of not participating in vigorous exercise is significantly related to all sociodemographic variables examined. Reasons for these associations are discussed. (shrink)

Investigation of neural and cognitive processes underlying individual variation in moral preferences is underway, with notable similarities emerging between moral- and risk-based decision-making. Here we specifically assessed moral distributive justice preferences and non-moral financial gambling preferences in the same individuals, and report an association between these seemingly disparate forms of decision-making. Moreover, we find this association between distributive justice and risky decision-making exists primarily when the latter is assessed with the Iowa Gambling Task. These findings are consistent with neuroimaging (...) studies of brain function during moral and risky decision-making. This research also constitutes the first replication of a novel experimental measure of distributive justice decision-making, for which individual variation in performance was found. Further examination of decision-making processes across different contexts may lead to an improved understanding of the factors affecting moral behaviour. (shrink)

If payoffs are tickets for binary lotteries, which involve only two money prizes, then rationality requires expected value maximization in tickets. This payoff scheme was increasingly used to induce risk neutrality in experiments. The experiment presented here involved lottery choice and evaluation tasks. One subject group was paid in binary lottery tickets, another directly in money. Significantly greater deviations from risk neutral behavior are observed with binary lottery payoffs. This discrepancy increases when subjects have easy access to (...) the alternatives' expected values and mean absolute deviations. Behavioral regularities are observed at least as often as with direct money payoffs. (shrink)

The main aim of the paper is to present the results of research concerning psychological and socio-cultural risk factors for development of negative anti-health attitude toward one’s body in young Polish women. The study comprised 120 women, of 20 to 25 years of age, with similar socio-demographic status who so far in the course of their lives have not disclosed mental or somatic disturbances. The theoretical theses for the research model were the contemporary cognitive concepts, as well as socio-cultural (...) concepts. The following have been used in the study: thematic drawings, the Contour Drawing Rating Scale developed by - developed by Thompson & Gray, the Eating Disorder Inventory created by D. Garner, The Sociocultural Attitudes Towards Appearance Questionnaire 3, and questionnaire for behaviour towards the body. The results confirmed the existence of negative attitude toward one’s own body, as well as development of inclinations for compensation-generating behaviour. A group of risk factors has been identified, which may lead to the development of the above attitudes and behaviours toward one’s body in healthy women, who at the same time do not accept the image of their real bodies.

Are risk behaviours in adolescence differentiated according to same-sex vs opposite-sex interest? For all respondents a five-point scale of interest in each sex used information from both of the first two in-home waves of the National Longitudinal Study of Adolescent Health (Add Health). Logistic regression predicted the probability of experiencing each risk behaviour from the same-sex and opposite-sex interest scores. Same-sex interests have more effect on emotional risk, and opposite-sex interests have more effect on substance use. Nevertheless, (...) all risk variables except boys’ depression are responsive to both same-sex and opposite-sex interest. The same-sex interest component of risk is attributed to the emotional strain of living with an anomalous sex interest in a heterosexual society. (shrink)

As software piracy continues to be a threat to the growth of national and global economies, understanding why people continue to use pirated software and learning how to discourage the use of pirated software are urgent and important issues. In addition to applying the theory of planned behavior (TPB) perspective to capture behavioral intention to use pirated software, this paper considers perceived risk as a salient belief influencing attitude and intention toward using pirated software. Four perceived risk (...) components related to the use of pirated software (performance, social, prosecution and psychological risks) have been identified, measured and tested. Data were collected through an online survey of 305 participants. The results indicate that perceived prosecution risk has an impact on intention to use pirated software, and perceived psychological risk is a strong predictor of attitude toward using pirated software. In addition, attitude and perceived behavior control contribute significantly to the intended use of pirated software. However, the proposed direct relationship between subjective norm and intention to use pirated software is not supported. Implications for research and practice are discussed. (shrink)

Repeated unethical behaviour by consumers is a serious challenge for participants in business transactions, including consumers, retailers, and those responsible for market supervision. Due to the inherent risk of such behaviours, we examine perceived risk to uncover the psychological mechanism by which consumers consider past behaviour (PAB) when deciding to repeat unethical behaviour. We divide perceived risk into two categories, material risk (MAR) and nonmaterial risk (NMR), based on two kinds of ethical evaluation and explore (...) their mediating effects in the process through which PAB influences consumers' intentions to repeat unethical behaviour (CIRUB). We check the moderating effect of consumers' ethical beliefs on the relationship between PAB and CIRUB. We use survey data from four typical ethical scenarios to test the proposed structural relationships. Direct positive effects of PAB on consumers' intentions are observed in all four scenarios. NMR has stable, positive mediating effects in all scenarios. MAR is found to have negative mediating effects in two scenarios (switching price tags and using an expired coupon) and a positive effect in one scenario (copying software). However, no effect is observed in the benefiting from a cashier's mistake scenario. Finally, ethical beliefs are proven to positively moderate the relationship between PAB and consumers' intentions in the first two scenarios, but not the last two. This study also discusses the implications of the findings and offers suggestions for future research. (shrink)
