A qualitative exploration of alcohol use among student sportspeople: A social identity perspective

Research indicates that university student sportspeople are a high‐risk subgroup for hazardous alcohol consumption. Adopting a social identity perspective, we explored the social and psychological processes linking sports participation and alcohol use. Twenty‐two individual semi‐structured interviews were conducted with UK student sportspeople (male: 12; female: 10). A deductive thematic analysis identified three core themes: social identification and sports group membership, identity processes in (alcohol) behaviours and sport context‐specific significance of alcohol. Results suggest that the consumptive practices among student sportspeople were strategic activities underpinned by social identity processes, and which served to provide a positive sports experience at the group level. Our findings highlight the interactions between the sport environment, the social structure of sport participation and the multipurpose function of alcohol in this context. We discuss the implications of these results in support of a social identity approach to sport‐related drinking.     

Human factors in GIScience laboratory at the Pennsylvania State University

The human factors in GIScience Laboratory (Human Factors Lab) of The Pennsylvania State University’s Department of Geography is located in University Park, PA (USA). University Park and bordering State College, PA are found in the heart of PA between the cities of New York City, NY, Philadelphia, PA, and Pittsburgh, PA. The laboratory is directed by Dr. Alexander Klippel and is part of the GeoVISTA Center. The Human Factors Lab contributes to Penn State Geography’s strong tradition as a leader in research on map perception, spatial cognition, and behavior in spatial environments. This report focuses upon basic research topics in spatial cognition, including: (1) perceptual and cognitive factors in map symbolization and design, (2) the creation of cognitively ergonomic route directions for next generation location based services (LBS), (3) You-Are-Here maps and the creation of a sense of place through map-like representations, (4) the conceptualization and representation of dynamic phenomena (i.e., geographic movement pattern), and (5) the relationship between linguistic and non-linguistic conceptualization.     

Polydipsia induced by intermittent delivery of salted liquid foods

Food-deprived rats given constant access to water were exposed to fixed-time presentations of soybean milk and diluted sweetened condensed cows' milk. In some conditions these liquid foods were adulterated with varying amounts of sodium chloride. Under a fixed-time 30-sec schedule of food delivery, little water was consumed when the food was soybean milk alone, or soybean milk with sodium chloride added in concentrations of .9, 1.8, or 3.6%. However, schedule-induced polydipsia appeared when soybean milk adulterated with 7.2 or 14.4% sodium chloride was delivered under this schedule. When soybean milk containing 7.2% sodium chloride was presented under fixed-time 15-, 30-, 60-, 120-, and 240-sec schedules, schedule-induced drinking increased with the fixed-time value from 15 to 120 seconds, and decreased at 240 seconds. Like soybean milk, diluted sweetened condensed milk delivered under fixed-time schedules of 30, 60, and 120 seconds failed to evoke schedule-induced polydipsia, but did so when adulterated with 7.2% sodium chloride. Drinking induced by salted liquid foods resembled the polydipsia engendered by spaced dry-food presentations in several ways, including temporal relation to food delivery, persistence within and across sections, sensitivity to interfood interval, and magnitude relative to intake evoked by bulk-food presentation.     

同伴排斥与青少年早期饮酒行为:同伴侵害和不良同伴的中介效应

采用同伴提名、同伴侵害问卷、不良同伴问卷和饮酒行为问卷调查广东地区4所普通初级中学1386名7年级学生,考察了同伴排斥与青少年早期饮酒行为的关系,以及同伴侵害和结交不良同伴在其中的链式中介效应。结果发现:(1)同伴排斥、同伴侵害和结交不良同伴均与青少年早期的饮酒行为呈显著正相关;(2)同伴侵害和结交不良同伴在同伴排斥影响青少年早期饮酒行为过程中的链式中介效应显著,即同伴排斥通过增加同伴侵害,从而提高结交不良同伴的风险,进而增加青少年早期的饮酒行为;(3)在控制同伴侵害和结交不良同伴后,同伴排斥对青少年早期的饮酒行为仍存在显著预测作用。     

Early drinking onset: A study of prevalence and determinants among 13‐year‐old adolescents in Norway

Early drinking onset is associated with different psychosocial adjustment problems among adolescents. The aim of this study was to assess determinants associated with early drinking and to identify factors predicting early drinking onset among adolescents. The study included 1,550 eighth‐graders with a mean age of 13.5 years from 41 schools. A total of 24% (boys 29%, girls 19%) had ever drunk alcohol, while 14% had drunk some alcohol in the last 30 days. Further, early drinking was associated with gender, religion, school performance, smoking and bullying in the bivariate tests. Predictors of early drinking onset were identified by generalized linear mixed models with two multivariable models created. The first model included social and environmental variables. Entering intentions, expectancies, attitudes and norms into the multivariable analysis resulted in a significant improvement of the model fit constituting 86% in the second model. The percentage correctly classified those (56%) who had been drinking in the second model which was two times higher compared to the first model. Gender, religion and smoking emerged as significant predictors of drinking in both models.     

Relative reinforcing effects of different oral ethanol doses in rhesus monkeys

The relative reinforcing effects of different doses of orally delivered ethanol were evaluated. Mouth-contact responding by rhesus monkeys was measured under concurrent fixed-ratio fixed-ratio schedules of liquid delivery (0.67 ml/delivery) from each of two spouts during daily 3-hr sessions. Experiment 1 examined persistence of responding with ethanol (2%, 8%, and 32% wt/vol) and water available. When fixed-ratio values from 8 to 128 were tested, the number of ethanol deliveries obtained per session decreased as the response requirement increased. The decrease in deliveries was less at higher than at lower ethanol concentrations, however. Experiment 2 examined choice between two ethanol concentrations under concurrent fixed-ratio 16 schedules (4% vs. 8%, 4% vs. 16%, 8% vs. 16%, 2% vs. 8%, 2% vs. 32%, 8% vs. 32%). Higher concentrations (16%, 32%) generally maintained more responding than concurrently available concentrations of 8% or less. An exception was the observation of a preference for 8% over 32% ethanol. When the fixed-ratio value was increased, however, the relative preference for these two doses was reversed so that 32% ethanol maintained more responding than 8% ethanol. Thus, the direction of the preference depended on the size of the response requirement. These results indicate that the reinforcing effects of ethanol increase with dose.     

饮酒期望、饮酒拒绝自我效能与青少年的饮酒行为:有中介的调节效应分析

以544名初一、初二、高一和高二的学生为研究对象,考察在控制了相关人口学变量后,消极饮酒期望对积极饮酒期望与青少年饮酒行为关系的调节作用,以及饮酒拒绝自我效能对消极、积极饮酒期望及两者交互作用与饮酒行为关系的中介作用。结果发现:(1)28.31%的中学生在过去一个月中曾饮酒,其中13.60%在过去一个月中曾大量饮酒,8.27%曾醉酒;(2)积极饮酒期望能正向预测青少年的饮酒行为,消极饮酒期望在积极饮酒期望与青少年饮酒行为关系中发挥调节作用;(3)饮酒拒绝自我效能在消极饮酒期望与饮酒行为关系中起部分中介作用,在积极饮酒期望与饮酒行为的关系以及消极饮酒期望的调节作用中发挥了完全中介作用;(4)调节效应的中介机制表明,低消极期望组中,随着积极期望的提高,饮酒拒绝自我效能呈直线下降的趋势;而在高消极期望组中,无论积极期望高或者低,饮酒拒绝自我效能均较高。研究结果对青少年饮酒行为的干预有重要的指导意义。     

父母和同伴因素对青少年饮酒行为的影响

环境是影响青少年饮酒行为的重要因素之一。本研究以南京市初一、初二、高一、高二共995个中学生为被试,考察父母和同伴因素对青少年饮酒行为的影响以及相对影响力。要求青少年自我报告他们自己、父母和同伴的饮酒行为和态度以及父母监控、父母教养方式情况。结果表明:(1)青少年的饮酒行为较为普遍,70%左右的青少年曾饮过啤酒或葡萄酒,25%左右的青少年曾饮过白酒。约10%的青少年经常饮啤酒和葡萄酒,2%的青少年经常饮白酒;(2)父/母饮酒行为和态度、父母监控、父母教养方式、同伴饮酒人数和态度与青少年的饮酒行为显著相关;(3)Amos结果表明,父母饮酒行为和态度对青少年饮酒行为有直接的预测作用,父母饮酒行为和态度还通过同伴饮酒人数和态度间接地预测青少年的饮酒行为。同时,父母饮酒行为和态度对青少年饮酒行为的影响力大于同伴饮酒行为和态度的影响力。
