Impact of question-answering tasks on search processes and reading comprehension     

Raquel Cerdán  Eduardo Vidal-Abarca  Tomás Martínez  Ramiro Gilabert  Laura Gil 《Learning and Instruction》2009,19(1):13-27

This study examined the effect of (a) high- and low-level questions and (b) reading the text before the questions asked on performance, delayed text recall, and deep text comprehension, as well as on specific text-inspection patterns. Participants were 37 undergraduate students who answered either high- or low-level questions using the software Read&Answer to read and answer questions on the computer screen. Additionally, half of the sample read first a text and then answered the questions (reading-first condition), whereas the other half answered the questions without having read the text in advance (no-reading-first condition). All participants had the text available to search for the answer. Results indicated that high-level questions facilitated deep comprehension but not immediate performance or delayed recall of text, independently of the reading condition, and that high- and low-level questions differentially affected text-inspection patterns.  相似文献

The changing of the sponsorship market     

P. Berkes  M. Nyerges  J. Váczi 《Sportwissenschaft》2009,39(1):35-44

Since the time of state socialism, Hungarian sport has been totally financed by the state. Therefore, Hungarian soccer and sponsorship market is a relatively new and unexplored subject of research in the field of sports sponsorship, as most studies so far have focused on the major European soccer leagues. The main objective of this paper, focusing on the Hungarian soccer sponsorship market, was to evaluate the range of soccer sponsorship objectives and the range of evaluation tools that sponsors use to measure the effectiveness of their sponsorships. A combined approach of qualitative and quantitative research methods served as the methodological foundation of this study. In the quantitative phase, representatives of the sponsor companies (n=103) were asked to rate the importance of the sponsorship objectives and the importance of the evaluation techniques used to measure the effectiveness of their sponsorships. The results of this study have implications for the sports sponsorship industry, the Hungarian soccer club sponsors, and the sport properties too. According to the research results, many of the Hungarian sponsor companies have failed to assess the effectiveness of sponsorship in meeting their objectives. The research can be used to bridge the gap between the theory and practice of soccer sponsorship in Hungary.  相似文献

Gender Verifications in Sport: From an East/West Antagonism to a North/South Antagonism     

Anaïs Bohuon 《国际体育史杂志》2015,32(7):965-979

This paper aims to analyze gender verifications in sport from a socio-historical approach. These medical controls intended to keep men from competing in women's international competitions. Some female athletes are put through a masculinization trial, because of morphologies and performances judged as too masculine. Facing these athletes who disrupt the representation of a binary construction between the male sex and the female sex, sports institutions attempt to maintain a sexual bi-categorization. More precisely, this paper will present the ‘symbolic’ suppression of tests since 2000. Thereafter, authorities only rely on an aesthetic and visual assessment of female bodies and no longer use tests in a systematic and obligatory fashion. This reveals the moving boundary subjectively plotted between the masculine and the feminine, which become all the more blurred when the ‘race and class markers’ interfere with the ‘sex markers’.  相似文献   

Intentional thought dynamics during exercise performed until volitional exhaustion

Using a non-linear approach, intentional dynamics of thoughts were examined during constant cycling performed until volitional exhaustion. Participants (n = 12) completed two sessions at 80% W_max. Their (1) intrinsic thought dynamics (i.e., no-imposed thoughts condition) and (2) intentional thought dynamics (i.e., imposed task-unrelated thoughts condition; TUT) were recorded and then classified into four categories: internal and external TUT (TUT-I, TUT-E) and external and internal task-related thoughts (TRT-E, TRT-I). The probability estimates for maintaining each thought category stable, the rate of switching from one category to another, and the entropy dynamics along the testing procedure were assessed and compared through time phase. Friedman ANOVA tests revealed a significant effect of effort increase on thought contents only in the imposed TUT test. While TUT-I probabilities decreased significantly (P < .001) as effort increased, TRT-I probabilities increased (P < .05). Moreover, the entropy to the entire thought dynamics increased at the outset of task performance and decreased upon approaching volitional exhaustion (P < .001). As time spent in constant effort increased, and volitional exhaustion approached, task relatedness (TUT, TRT), direction (internal, external), and entropy of thought contents changed unintentionally providing further evidence for a nonlinear dynamics of attention focus.  相似文献   

Pawns in a Chess Game     

Gloria García González 《Media History》2015,21(4):412-425

The Spanish Service was established in June 1939, two months after the end of the civil war in Spain and shortly before the start of the Second World War. Its implementation was strongly affected by these conflicts in the context of new international relations. Therefore, this study of the Spanish Service during 1939–1945 allows not only a better understanding of the communicational strategies developed by the BBC, but also of the complex Anglo-Spanish relations and the important role played by the Spanish-language broadcasts therein. The study is mainly based on archival documents from the National Archives in London and memoirs.  相似文献
