Sports betting advertising has arguably permeated contemporary sport consumption in many countries. Advertisements build narratives that represent situations and characters that normalize betting behaviour and raise public concerns regarding their detrimental effect on vulnerable groups. Adopting a grounded theory approach, the present study examined a British sample of sports betting advertisements (N = 102) from 2014 to 2016. The analysis revealed that individual themes aligned in a single core narrative, constructing a dual persuasive strategy of sports betting advertising: (i) to reduce the perceived risk involved in betting (with themes such as betting with friends, free money offers, humour, or the use of celebrities) while (ii) enhancing the perceived control of bettors (including themes of masculinity and sport knowledge). In addition, new technological features of sports betting platforms (e.g. live in-play betting) were used by advertisers to build narratives in which the ability to predict a sports outcome was overlapped by the ability of bettors to use such platforms, equalizing the ease of betting with the ease of winning. Based on the data analysed, it was concluded that the construction of a magnified idea of control in sports betting advertising is a cause for concern that requires close regulatory scrutiny. 相似文献

Preschoolers are more likely to endorse testimony supported by strong arguments than by weak, circular ones. Two‐year‐olds exchange arguments with others, but no experiment has demonstrated that they are sensitive to information presented as argument. In the first phase of this study, 2‐year‐olds were shown ambiguous pictures—for instance a bird–fish hybrid—and asked what they thought the picture represented. An informant then contradicted them, providing either a strong argument, a circular argument, or no argument, and the children were asked what they now thought the hybrid was. The second phase was identical to the first, with new hybrids, except that the informant never provided any argument for her position. Finally, in the third phase, the informant left the room and the children were asked again to tell what the hybrids from the first two phases were. On the whole, there was an effect of the amount of information provided in the argument so that children were more likely to endorse labels provided by the informant who had supported her answer with a strong argument in the first phase. Moreover, they generalized the trust granted to informants who provided strong arguments. These results constitute the first experimental demonstration that 2‐year‐olds possess some argument evaluation skills. 相似文献

Infants born preterm have higher risks of developing linguistic deficits. Considering that the ability to segment words from fluent speech is crucial for lexical acquisition, Experiment 1 tested the ability of healthy extremely‐to‐late preterm infants to segment monosyllabic words at 6 months of postnatal age. Results establish basic segmentation skills in these infants. While we failed to find an effect of the degree of prematurity, this issue will need further exploration. Future studies will also have to specify the scope of these early segmentation skills, both in terms of the types of words segmented, the cues used to do so, and in terms of possible differences in performance between subgroups of preterm infants (e.g., based on gestational age or medical risks). Lastly, given that the preterm infants tested had a mean maturational age of 4 months, Experiment 2 explored monosyllabic segmentation in full‐term 4‐month olds. Infants succeeded at the task, providing the earliest developmental evidence of word segmentation in full‐term infants. These findings better specify the early trajectory of segmentation abilities in both full‐term and healthy, low‐risk preterm infants and support the proposal that prematurity might have a differential effect on the early acquisition of various linguistic levels. 相似文献

Theory and Practice? A Comparative Analysis of Migration and Development Policies in Eleven European Countries and the European Commission 下载免费PDF全文
Niels Keijzer Julie Héraud Malin Frankenhaeuser 《International migration (Geneva, Switzerland)》2016,54(2):69-81
This article analyses international policy discussions on migration and development (M&D) and contrasts these with the actual M&D policies and practices of 11 European countries who were among the main proponents of this international discourse. Desk research of public documents and accompanying information sought from these 11 governments as well as in the European Commission (EC) provide the basis for a comparative analysis of their overall M&D policies and strategies, and institutional settings for formulating and implementing these. The comparison shows that M&D policy and practice remains in a tentative and experimental phase, and that countries experience difficulties reflecting their international positions in their own policies, as well as in learning from their own efforts and those of others. While stressing the developmental potential of migration in international discussions, most of the countries’ policies still reflect an understanding of migration as a problem and a preoccupation with short‐term domestic interests. 相似文献

In Turkey, there is a shortage of studies on the prevalence of sexual aggression among young adults. The present study examined sexual aggression victimization and perpetration since the age of 15 in a convenience sample of N = 1,376 college students (886 women) from four public universities in Ankara, Turkey. Prevalence rates for different coercive strategies, victim-perpetrator constellations, and sexual acts were measured with a Turkish version of the Sexual Aggression and Victimization Scale (SAV-S). Overall, 77.6% of women and 65.5% of men reported at least one instance of sexual aggression victimization, and 28.9% of men and 14.2% of women reported at least one instance of sexual aggression perpetration. Prevalence rates of sexual aggression victimization and perpetration were highest for current or former partners, followed by acquaintances/friends and strangers. Alcohol was involved in a substantial proportion of the reported incidents. The findings are the first to provide systematic evidence on sexual aggression perpetration and victimization among college students in Turkey, including both women and men. 相似文献

Based on the Social Representations Theory (SRT) applied to the social construction of risk and the role played by group identities, this study examines the construction of risk created by the mass media in health epidemics. An experimental design with split-ballot questionnaire and 319 participants was used in which message framing (human interest vs. attribution of responsibility) and proximity (high vs. low) were manipulated for a high invulnerability identity (youth) vs. a low invulnerability identity (elderly) population. Results showed that the human interest framing increased the perception of risk, especially when the proximity of the epidemic was high; this effect was explained by people’s emotional response. Furthermore, youth projected the risk towards ‘the other’ in order to protect their invulnerability identity. Finally, we stress the importance of the SRT on a theoretical and applied level for risk communication in health crises. 相似文献
