Being tolerated and minority well-being: The role of group identifications     

《Int J Intercult Relat》2020

In recent decades, a norm of tolerating group differences has been promoted by laypeople and leaders as a way to manage cultural and religious diversity. But whether such a policy is beneficial for the targets’ sense of group belonging and well-being is unknown. This research investigates how being tolerated differs from being discriminated against and being accepted in its associations with affective well-being and ethnic and national identification of ethnic minorities. We test whether being tolerated is related to well-being through its association with both group identifications. With a sample of ethnic minority group members in the Netherlands (N = 518) we found that being tolerated is related to higher well-being through increased national identification, but not as strongly as being accepted. Being tolerated is different from experiencing discrimination against and being accepted, and its relations to well-being and group belonging often fall between those of discrimination and acceptance. Toleration is associated with higher well-being, but only to the extent that its targets feel included in the overarching national category.  相似文献   

上海“体教结合”举措下竞技体育后备人才“学生-运动员”双重角色的认同、冲突与转化          下载免费PDF全文

侯爽 《体育科研》2019,(3):30-37

“体教结合”是解决当前我国竞技体育发展问题的重要途径和举措。传统的体育后备人才培养模式只重视专项体育技能的发展而忽视了文化教育的重要性，不利于个体的全面发展。“体教结合”更重视人的全面发展，体育与教育的融合，使得竞技体育人才逐渐从运动员这一单一角色向“学生-运动员”双重角色转变。研究以角色认同为切入口，探讨上海“体教结合”举措下，角色的转变对体育竞技后备人才的影响。选取上海体育学院中国乒乓球学院少年班学员作为“学生-运动员”样本，选取国家乒乓球青年队及部分省市队队员作为职业运动员样本，使用结构化心理测量工具，对比两类受访者在运动与学业上的角色认同、心理倦怠与动机变量的差异。得出：在上海“体教结合”举措下，竞技体育后备人才认同“学生-运动员”双重角色，他们在学业任务中的卷入程度更高；双重角色使运动员在运动任务与学业任务上的主观价值感存在差异，表现出双重角色之间的冲突，但对个体的整体人生规划并不冲突；双重角色之间的转化，对于“学生-运动员”的心理健康存在促进效应。  相似文献

Team identification and sports fandom as predictors of fan aggression: The moderating role of ageing     

《Sport Management Review》2019,22(2):194-208

In the current study, the explored the moderating role of ageing in the relationship between team identification/fandom and fan aggression. The authors used an online panel-based survey that offered access to a realworld population of sports fans. Participants were 740 fans of Israeli professional basketball. Results from structural equation modelling demonstrated that older fans reported higher levels of mere sports fandom and lower levels of self-reported aggression and acceptance of aggression. Moreover, age moderated the relationships between team identification (or fandom) and self-reported aggression, such that team identification (or fandom) was more strongly associated with selfreported fan aggression among younger fans than among older fans. The moderating role of age in the relationships between team identification (or fandom) and perceptions of appropriateness of aggression was not supported. The findings contribute to our theoretical understanding of the role of ageing in the relationship between fan identification and fan aggression. Based on these findings, the authors assert that managers might particularly benefit from leveraging the potential, but often neglected, segment of senior fans, since older fans can play a key role in reducing the level of aggression during competitive sports events. Suggestions for future research are also discussed.  相似文献   

Writer identification approach based on bag of words with OBI features     

Amal Durou  Ibrahim Aref  Somaya Al-Maadeed  Ahmed Bouridane  Elhadj Benkhelifa 《Information processing & management》2019,56(2):354-366

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.  相似文献   

An exploration of young professional football players’ perceptions of the talent development process in England     

《Sport Management Review》2020,23(3):536-547

The identification and development of players in English professional football has become an increasingly significant topic of debate given the historical perceived underperformance of the English national team at international tournaments. To enhance understanding of the challenges and barriers experienced by English youth footballers, the authors explore the developmental experiences of English professional football players from different levels of the English football pyramid. Professional players (N = 11) from football clubs in the top four professional divisions in England took part in individual semi-structured interviews, which were analysed inductively using thematic analysis. The data revealed three interrelated themes that were perceived to mediate player identification and development pathways at professional clubs. Pathways for young players to progress and experience first-team competitive football differed when the level of the league that the players operated within was considered, with significant issues also raised relating to the suitability of the under 21 league structure, the importance attached to the educational welfare of young players, and variations in the identification of player attributes. This study sheds new light on the priorities and processes of talent development and education provision in English football.  相似文献   

Third-grader's think-aloud protocols: Types of reading activities in reading an expository text     

Gonny Schellings  Cor Aarnoutse  Jan van Leeuwe 《Learning and Instruction》2006,16(6):549-568

In the present study, we examined the reading activities of young readers, while reading an expository text. A total of 24 third-graders was administered a think-aloud task on two occasions. Their protocols were analysed by a coding system that captured two levels of the reading process: the word identification level and the reading comprehension level. Three indices reflecting three different types of reading activities were discerned: reading errors, reproduction, and activities referring to reading strategies. Correlational analyses showed the reading strategy index to be related to reading comprehension as measured by standardized tests. The think-aloud task constitutes a valuable instrument for examining strategic reading among young readers.  相似文献

Nucleic acids in plant tissue lysates can be captured quickly by a cellulose filter paper and prepared for amplification after a quick purification.In this study,a published filter paper strip method was modified by sticking the filter paper on a polyvinyl chloride resin(PVC)sheet.This modified method is named EZ-D,for EASY DNA extraction.Compared with the original cetyl trimethylammonium bromide(CTAB)method,DNA extracted by EZ-D is more efficient in polymerase chain reaction(PCR)amplification due to the more stable performance of the EZ-D stick.The EZ-D method is also faster,easier,and cheaper.PCR analyses showed that DNA extracted from several types of plant tissues by EZ-D was appropriate for specific identification of biological samples.A regular PCR reaction can detect the EZ-D-extracted DNA template at concentration as low as 0.1 ng/μL.Evaluation of the EZ-D showed that DNA extracts could be successfully amplified by PCR reaction for DNA fragments up to 3000 bp in length and up to 80%in GC content.EZ-D was successfully used for DNA extraction from a variety of plant species and plant tissues.Moreover,when EZ-D was combined with the loop-mediated isothermal amplification(LAMP)method,DNA identification of biological samples could be achieved without the need for specialized equipment.As an optimized DNA purification method,EZ-D shows great advantages in application and can be used widely in laboratories where equipment is limited and rapid results are required.  相似文献
