Projective techniques for brand image research: Two personification‐based methods explored

Purpose – Since it is hard for consumers to express their feelings and views regarding brand images, market researchers increasingly use projective and enabling techniques to collect rich and meaningful data. The purpose of this paper is to describe the development and use of two methods of brand image research based on personification. Both methods were used to investigate the personality of four beer brands.Design/methodology/approach – The first method was based on mood boards: participants were asked to make collages of celebrity photographs representing the beer brands (n=16). The second method used a job‐sorting task: participants were asked to connect jobs with the beer brands (n=100). The results of both methods were related to a list of brand personality traits.Findings – Holistic interpretations of the mood boards and the jobs associated with the beer brands reveal highly similar results among the two methods, which strongly discriminate between the four beer brands. A translation of these findi...

Adolescent alcohol intoxication in the dutch hospital departments of pediatrics: A 2-year comparison study

PURPOSE To monitor the prevalence of, and the circumstances leading to, adolescent alcohol intoxication admissions in Dutch hospital departments of pediatrics. METHODS Data were collected in 2007 and 2008, using the Dutch Pediatric Surveillance System, in which pediatricians received questionnaires on varying issues, including adolescent alcohol intoxication admissions. RESULTS The adolescents treated in 2008, as in 2007, were average youth across proportion of gender, educational level, school performances, family structure, siblings, familiarity with medical or aid agencies, alcohol use, and other (illicit) drug use. In 2008, 13% more adolescents were treated. These adolescents showed a trend of having a younger average age, higher blood alcohol concentrations, and longer durations of mental impairment. About 45% of the adolescents who were treated for alcohol intoxication had purchased alcohol from a commercial place, despite that 51 times the specific adolescent had not reached the legal age of 16 years old. About one-third of the youngsters consumed alcohol at home or at a friends home. CONCLUSIONS The number of adolescents suffering from alcohol intoxication increased in 2008 compared with 2007. Parental (lack of) involvement and responsibilities of commercial sales personnel are discussed.

Son, you’re smoking on Facebook! College students’ disclosures on social networking sites as indicators of real-life risk behaviors

Health risk behavior in student populations is an issue of major concern, and students’ risk levels are difficult to determine. In this study, we explore the extent to which information disclosed publicly on Facebook provides reliable indications of five real-life health behaviors. Questionnaire data and Facebook contents (2928 items) on alcohol use, smoking, illicit drug use, (un)healthy nutrition, and participation in sports of 71 respondents were collected and analyzed. The study shows that one can analyze Facebook profiles to reliably associate profile owners’ smoking and sport behavior. It also shows that regarding alcohol use, some Facebook profile elements are indicative of real-life drinking. We discuss and suggest improved methods of coding disclosed public data, which may lead to reliable indications of peoples’ real-life behavior

Why should I comply? Sellers’ accounts for (non-)compliance with legal age limits for alcohol sales

BackgroundAvailability is an important predictor of early and excessive alcohol consumption by adolescents. Many countries have implemented age limits to prevent underage purchases of alcohol. However, shop-floor compliance with these age limits appears to be problematic. This study addresses the issue of non-compliance with age limits. Which measures do vendors take to avoid underage alcohol sales, and what do they report as important reasons to comply or not with age limits for alcohol sales?MethodsOpen-ended telephone interviews were conducted with store managers selling alcohol (N = 106). Prior to the interviews, all outlets were visited by an underage mystery shopper in order to measure compliance with the legal age limits on alcohol sales. The interview results are compared against actual compliance rates.ResultsSeveral measures have been taken to prevent underage sales, but the compliance level is low. Furthermore, open coding resulted in 19 themes, representing both valid and invalid arguments, that vendors mentioned as relevant to their decisions of whether to comply with the law. Compliance with age limits is dependent on the knowledge of the rules and the ability and motivation to follow the rules. The ability aspect in particular seems to be problematic, but in many cases, the motivation to actively comply with the age limits is lacking.ConclusionsTo enhance compliance, it is important to raise the awareness of the importance of age limits and to connect possible violations of the regulations to negative consequences.

Generosity the Second Time Around: Determinants of Individuals’ Repeat Donation Intention

Studies into the factors influencing first-time monetary donation intention abound. However, the determinants of repeat donation intention have not yet received significant attention within the academic community. For this study, a survey was implemented with residents of two cities in the eastern part of the Netherlands to determine the factors influencing their repeat donation intention. The study shows that respondents’ intention to continue donating to a charitable organization is predicated on their positive experience with that organization. Furthermore, this repeat donation is also influenced by respondents’ affinity with the cause of the charitable organization, their trust in the organization, and the organization’s positive reputation. The perceived risk of donating negatively influences repeat donation intention. It is surprising, however, that a sense of moral obligation to help others does not impact respondents’ intention to continue donating.

Gender, age, and educational level attribute to blood alcohol concentration in hospitalized intoxicated adolescents; a cohort study.

BACKGROUND The prevalence of adolescents hospitalized with acute alcohol intoxication, mainly because of severe reduced consciousness, is increasing. However, the characteristics of these adolescents are mainly unidentified. In this clinical research, we aimed to identify factors that attribute to higher ethanol concentration, on which targeted alcohol health interventions can be designed. METHODS Since 2007, alcohol intoxication among adolescents has been one of the leading topics of the Dutch Pediatric Surveillance System. In the current study, we have analyzed which demographic characteristics, general alcohol use behaviors, and clinical intoxication data were related to the blood alcohol concentration (BAC) levels at hospital admittance. We included all adolescents aged <18 years, admitted with BAC >0.0 g/l, and reduced consciousness during the years 2007, 2008, 2009, and 2010. RESULTS A total of 2,023 adolescents with alcohol intoxication were reported, and 1,618 questionnaires were returned, of which 1,350 met our inclusion criteria. In univariate analysis, age, gender, educational level, place of alcohol purchase, place of alcohol consumption, age of first drink, and regular alcohol use during the weekend correlated with higher BAC. After multivariate analysis, older adolescents, boys, and higher educational level significantly attributed to higher BAC at admittance. CONCLUSIONS In alcohol-intoxicated adolescents with reduced consciousness, gender, age, and also educational level correlate with BAC at admittance. Explanatory factors could be found in sensitivity to alcohol, but also in socioeconomic factors, which influence availability. Intervention strategies could be targeted more specific now for the subgroups found in this study to decrease the growing burden of adolescent alcohol intoxication, both on the societal level and on the clinical level.

Private peer group settings as an environmental determinant of alcohol use in Dutch adolescents: Results from a representative survey in the region of Twente

This study supports the hypothesis that the drinking setting can be an environmental risk factor for hazardous alcohol use. In a survey of Dutch adolescents (n = 1516), alcohol consumption and participation in private peer group settings (PPSs), environments where adolescents meet and drink alcohol without direct adult supervision, were measured. After controlling for demographic variables, adolescents visiting PPSs as compared to non-visitors, appeared to have a significantly higher lifetime prevalence of alcohol use, average weekly consumption, and frequency of heavy episodic drinking. Moreover, accounting for school clustering, the frequency of PPS visits was associated with increased alcohol consumption.

Media rating systems: do they work? Shop floor compliance with age restrictions in the Netherlands

Media rating systems have been introduced in many countries to protect minors from being exposed to harmful media content. This study examines whether retailers comply with the guidelines of media ratings in the Netherlands. In a mystery shopping study, minors tried to buy or rent media products for which they were too young. An overall success rate of 86% shows that compliance on the shop floor is problematic. In a mystery call study, parents asked vendors for advice about media ratings. Only 33% of the parents were advised in accordance with the age classifications. A survey of vendors investigated the determinants of compliance. Personal acceptance, awareness of a legal basis, and perceived surveillance proved to be important determinants of self-reported compliance.

Voters' Perceptions of Voting Technology

Despite their unmistakable advantages, the use of voting machines in elections is a topic of vivid debates. This article focuses on the experiences of voters using three types of voting equipment: (a) a paper ballot, (b) a voting machine, and (c) a voting machine with paper audit trail. An independent-groups experiment was conducted in which voters had to cast a vote for a donation to a charity organization and afterwards filled out a questionnaire about their voting experiences. The paper ballot was considered to be the most anonymous way of voting, especially by female voters. The voting machine (with or without paper trail), on the other hand, was considered to be more user-friendly than the paper ballot and gave the voters more confidence that their votes would actually be processed correctly. No differences were found between the voting machine with and without paper audit trail.

Determinants of safety outcomes and performance : A systematic literature review of research in four high-risk industries

INTRODUCTION In spite of increasing governmental and organizational efforts, organizations still struggle to improve the safety of their employees as evidenced by the yearly 2.3 million work-related deaths worldwide. Occupational safety research is scattered and inaccessible, especially for practitioners. Through systematically reviewing the safety literature, this study aims to provide a comprehensive overview of behavioral and circumstantial factors that endanger or support employee safety. METHOD A broad search on occupational safety literature using four online bibliographical databases yielded 27.527 articles. Through a systematic reviewing process 176 online articles were identified that met the inclusion criteria (e.g., original peer-reviewed research; conducted in selected high-risk industries; published between 1980-2016). Variables and the nature of their interrelationships (i.e., positive, negative, or nonsignificant) were extracted, and then grouped and classified through a process of bottom-up coding. RESULTS The results indicate that safety outcomes and performance prevail as dependent research areas, dependent on variables related to management & colleagues, work(place) characteristics & circumstances, employee demographics, climate & culture, and external factors. Consensus was found for five variables related to safety outcomes and seven variables related to performance, while there is debate about 31 other relationships. Last, 21 variables related to safety outcomes and performance appear understudied. CONCLUSIONS The majority of safety research has focused on addressing negative safety outcomes and performance through variables related to others within the organization, the work(place) itself, employee demographics, and-to a lesser extent-climate & culture and external factors. PRACTICAL APPLICATIONS This systematic literature review provides both scientists and safety practitioners an overview of the (under)studied behavioral and circumstantial factors related to occupational safety behavior. Scientists could use this overview to study gaps, and validate or falsify relationships. Safety practitioners could use the insights to evaluate organizational safety policies, and to further development of safety interventions.
