Tilt in poker implies a deviation from an individual’s usual playing style, at a strategic, emotional and behavioural level. It is a specific characteristic of poker, which can affect all kinds of players with varying degrees of frequency. In addition, tilt could be a transitional form of pathological gambling behaviour and a gateway to addiction. The main objective of this research is therefore the design and validation of a measuring scale for tilt episode frequency in an online poker gamblers’ group. Twenty-one items based on the literature and interviews with 10 poker players were created. An online self-administered questionnaire was completed by 263 poker players to validate this scale. The mean age of the sample was 26.7 (SD = 4.45). The Online Poker Tilt Scale (OPTS) consists of 17 items and is the first validated tool for measuring the frequency of tilt episodes associated with online poker. It is composed of two factors: ‘emotional and behavioural tilt’ and ‘cognitive tilt’. Tilt seems to be an essential part of understanding online poker behaviour. This tool will enable researchers studying online poker addiction to perform research on the mechanisms and processes that lead to tilt and its consequences.  相似文献

Previous research has demonstrated that social interactions underlie the development of object‐directed imitation. For example, infants differentially learn object action sequences from a live social partner compared to a social partner over a video monitor; however, what is not well understood is what aspects of social interactions influence social learning. Previous studies have found variable influences of different types of caregiver responsiveness on attention, language, and cognitive development. Therefore, the purpose of this study was to examine how the responsive style of a social partner influenced the learning of object‐directed action sequences. Infants interacted with either a sensitive or redirective experimenter before the learning trial. Results revealed infants changed their patterns of engagement; infants interacting with a sensitive experimenter had longer periods of attentional engagement than infants interacting with a redirective experimenter. Furthermore, during the learning trial, the amount of sensitivity during interaction with the social partner predicted learning scores. These findings suggest that infants' attention is influenced by social partners' interactive style during ongoing interaction, which subsequently affects how infants learn from these social partners.  相似文献

Framed by Relational Dialectics Theory, this study explores the ways adult, former foster children discursively construct meanings of “family.” Contrapuntal analysis of 24 interviews revealed two discourses as competing to constitute family: the Discourse of Family as Irreplaceable and Inescapable (Permanence) and the Discourse of Family as Performative Kinning (Performance). Permanence was constituted by themes of biology and historical connection, reifying normative understandings. Performance, comprised of role enactment, need for tolerance, and unconditional love, challenged the Permanence discourse. Throughout the narratives, Performance competed with Permanence for dominance, illustrating the cultural pervasiveness and power of Permanence yet, in some moments, privileging the marginalized Performance discourse. This discursive competition constructed meanings of family in narratives of life before, during, and after foster care. Overall, participant’s talk constructed complex webs of family relationships, allowing access to an important social institution—family—regardless of the presence/absence of culturally valued markers of family (e.g., biology, legality).  相似文献

This study assessed the knowledge and attitudes of young adults without children in regard to discipline and parenting practices. A qualitative design was utilized (n?=?26) with semistructured focus groups. Results indicated participants believed discipline is important, with spanking and loss of privileges being the most effective strategy for behavior change. The majority of participants reported plans to discipline future children the way in which they were disciplined, suggesting a high percentage intend to utilize spanking. Findings suggest that personal experiences shape parenting beliefs, attitudes, and knowledge. Results inform efforts at educating future parents on appropriate parenting practices and indicate the need for protocols for young adults to educate about practices that may diverge from their personal experiences.  相似文献

ABSTRACT

At the 2017 North Carolina Serials Conference, keynote speaker Regina Romano Reynolds—Director, U.S. ISSN Center and Head, ISSN Section at the Library of Congress—explored how bibliographic transformation can connect users to good-quality content. Offering examples of current and potential serials management projects, Reynolds shared her vision for breaking down information silos, experimenting in the resource management space, and the need for visionary leadership.  相似文献

Based on 55 qualitative interviews, this article looks in depth at the ways in which gendered expectations impact heterosexual romantic relationships among low‐income and poor adults in a small, western U.S. city. It finds that contradictory understandings regarding meanings and responsibilities associated with masculinity and femininity present challenges to the formation and sustaining of committed relationships. Although men desired to be providers and heads of household with limited household responsibilities, women wanted men with traditional work ethics but egalitarian perspectives on sharing both income generation and home and family responsibilities. Participants' unrealistic and conflicting gendered relationship expectations combined with economic concerns and social problems associated with economic strain to contribute to relationship tensions and wariness toward romantic involvements.  相似文献

Sexual harassment on college campuses is a frequent occurrence and serious public health concern. Victims of sexual harassment are at risk for many possible negative health consequences. In addition, certain psychological distress symptoms and/or alcohol use may put individuals at increased risk of being victims of sexual harassment. Data from more than 2,000 college students in the Midwestern United States were used to examine reciprocal causal effects of the relations between (a) experiencing sexual harassment and alcohol use and (b) experiencing sexual harassment and psychological distress symptoms, specifically depression and anger/hostility. Analyses were conducted separately for sexual harassment which occurs at school and which occurs in college students’ workplaces, and also separately for men and women. Results of cross-lagged panel models showed that there were reciprocal causal effects between sexual harassment and alcohol problems, depression, and anger. Discussion focuses on the overall patterns of results as well as the nuances within these findings.  相似文献
