Analysis of the predictive qualities of betting odds and FIFA World Ranking: evidence from the 2006, 2010 and 2014 Football World Cups

ABSTRACT

The present study aims to investigate the ability of a new framework enabling to derive more detailed model-based predictions from ranking systems. These were compared to predictions from the bet market including data from the World Cups 2006, 2010, and 2014. The results revealed that the FIFA World Ranking has essentially improved its predictive qualities compared to the bet market since the mode of calculation was changed in 2006. While both predictors were useful to obtain accurate predictions in general, the world ranking was able to outperform the bet market significantly for the World Cup 2014 and when the data from the World Cups 2010 and 2014 were pooled. Our new framework can be extended in future research to more detailed prediction tasks (i.e., predicting the final scores of a match or the tournament progress of a team).     

Affective response to gambling promotions during televised sport: A qualitative analysis

Gambling promotions extensively punctuate contemporary televised sport broadcasts and concerns have been raised about their potential impacts on vulnerable groups. Research suggests advertising can shape individuals’ emotions, or affect, towards a product/brand and can subsequently influence purchasing decisions. Consequently, understanding how promotion of gambling influences sport viewers is an important although sparsely addressed area of research. This paper presents exploratory research on affective responses towards gambling promotions displayed during televised sport. Eight online focus groups were conducted with a sample of regular sports viewers in Queensland, Australia. Participants were exposed to a variety of gambling promotions used in National Rugby League match telecasts. Utilising adaptive theory, themes reflecting affective responses to each promotional technique were identified. A range of positive and negative affective responses were identified including arousal, joy, anger and worry. A conceptual model representing emergent affective response categories, message delivery techniques and moderating variables is proposed to inform a broader future research agenda examining how gambling promotions during televised sport influence affective response and concomitant gambling intention.

Sports Gambling during the Second World War: A British Entertainment for Critical Times or a National Evil?

The catastrophe of the Second World War had a significant effect on British social and economic life, with less leisure and more time and energy spent on the war effort, yet sports betting survived. The paper begins by examining the arguments strongly advanced by vociferous anti-betting groups in the first years after the outbreak of war, and assesses their limited success. Assessments of betting turnover suggest an initial decline in betting, largely perhaps because of the brief curtailment of horse racing, dog racing, and football, the three principal betting media. The paper explores some of the reasons why it then once more increased, according to the surveys of the Churches Committee on Gambling or Mass Observation. The argument focuses on provision and betting organization: the continued legal opportunities within Britain, including new ‘unity’ football pools, the reopening of some English racecourses and dog-tracks, and the new opportunities created by illegal ready-money bookmakers, such as Irish horse-racing results, which were unaffected by the war. The national government took the view that the betting sports were ‘entertainments’ and ‘in the public interest’, and also helped by providing scarce petrol to assist with the movement of horses and dogs to meetings.     

Racing,Betting, Anti-Semitism and English Jewry 1800–1939

Historiography has largely focused on more respectable Anglo-Jewish leisure life in the nineteenth and early twentieth centuries, but this study uses the national and regional press, contemporary novels, books and magazines to explore non-Jewish representations of Jewish sports betting and related gambling involvement, and the extent to which such representations involved anti-Semitic attitudes. In part Jewish betting and gambling simply attracted similar respectable opprobrium to that of working-class gambling more generally, and prejudice was not a consistent feature. But at times, coverage suggested that Jews were greedier for money, less honest and more attracted to betting than other ethnic groups. Where Jews were involved in criminal activities, such as racecourse frauds in the 1840s, gaming room presence throughout the period, or the involvement of bookmakers in racecourse feuding in the inter-war period, such activities were sometimes deliberately foregrounded. Some rich Jews became involved in racehorse ownership, but with the exception of the Rothschild family they were excluded from Jockey Club membership. In the interwar period, the British Union of Fascists exploited any Jewish involvement in betting as part of their anti-Semitic propaganda.

晚清广东科举考试枪替之风初探

晚清科举考试中枪替风气盛行，但各地又存在着差异。在广东，“文风颇盛，弊亦最多”，地方政府和社会人士为防范科举考试中的枪替现象，采取了种种措施，这在一定程度上遏制了科场舞弊的泛滥，然而因科举制度自身的缺陷和闱娃赌博的影响，又使这些努力付诸东流。     

影响我国竞猜型体育彩票开设的初始机制——一个“理想类型”的提炼与分析

梳理运动项目影响竞猜型体育彩票开设的各种因素,提出项目的市场影响力是竞猜开设的基础,诱发赌博风险是催化和驱动力。为探究两者交互作用下的竞猜开设可能性,首先在逻辑上建构市场影响力和诱发赌博风险组合的"理想类型"分类,再从经验上考察我国足球、篮球、乒乓球、排球和赛马运动在分类中的位置及与竞猜的不同关联。最后,进一步提炼竞猜型体育彩票开设与发展的一般规律与可能变异,并探讨这一规律对推动我国竞猜型体彩发展的政策启示。     

Football matches: Decision making in betting

The aim of this paper is to approach the teaching of the Poisson distribution in a friendly and amusing way. It constitutes a common practice to adopt the main probability distributions in order to predict results of sport events and to estimate the win return of betting activities (Chalikias 2009). In particular, by using the Poisson distribution, we can calculate the probability of the final score in a football match, and then we can compare this probability with the values that various betting companies offer. Combining this information with the average of goals for both, it is possible to make a decision as to which betting company is more profitable for the betting players. The case study of the English Premier League is examined.
