Regulating online : participant-driven approaches

This thesis considers and evaluates different approaches to regulating online gaming communities, including traditional top-down regulation, as well as bottom-up and hybrid forms led by participants. I examine the regulatory environment in both the video game and gambling industries through case studies of the science fiction, massively multiplayer game Eve Online and offshore gambling platforms and their community sites. I identify that the participant driven approach to regulation sometimes used in the offshore gambling industry was dependent on a number of factors, notably the strength of the community and the risks to platform operators of negative publicity. By subsequently comparing this to the video gaming industry, I suggest that participant driven processes may be an appropriate way to resolve disputes in the games industry, and show how these are – to a limited extent – already being applied.

Aspects of Keno modelling

In two earlier papers, an intricate Jackpot structure and analysis of pseudo-random numbers for Keno in the Australian state of Queensland circa 2000 were described. Aspects of the work were also reported at an international conference . Since that time, many aspects of the game in Australia have changed. The present paper presents more up-to-date details of Keno throughout the states of Queensland, New South Wales and Victoria. A much simpler jackpot structure is now in place and this is described. Two add-ons or side-bets to the game are detailed: the trivial Heads or Tails and the more interesting Keno Bonus, which leads to consideration of the subset sum problem. The most intricate structure is where Heads or Tails and Keno Bonus are combined, and here, the issue of independence arises. Closed expressions for expected return to player (ERTP) are presented in all cases.

ANZAC Day media representations of women in Perth, 1960 – 2012

The annual Anzac Day observance is a focus for articulating popular notions of Australian national identity. Early Anzac Day observations were characterised by a diversity of observational modes, many distinctly masculine and militarist in character; including sports, competitions and marches. It was from the late 1920s that the now characteristic structure of the day (dawn service - march -follow-on - afternoon celebrations including eating, drinking and playing of the gambling game two-up, illegal on every other day of the year} became the dominant form. 1 Widely believed to have experienced an extended nadir in the 1960s and 1970s, since the 1980s Anzac Day has arguably become the single most important national event in the Australian calendar, involving probably the largest-numbers of Australians, many of them young, in the same temporal observance in a multitude of locations across the country and around the world.2 To date, there is a rich literature around Anzac Day observations and meanings focussing on its cultural I folkioric role'; the production of (masculinised) national identity;pilgrimage;' popular memory I history;' and the contemporary reshaping of the Anzac myth by and for indigenous participants.'

Confidence measurement in the light of signal detection theory

We compare three alternative methods for eliciting retrospective confidence in the context of a simple perceptual task: the Simple Confidence Rating (a direct report on a numerical scale), the Quadratic Scoring Rule (a post-wagering procedure), and the Matching Probability (MP; a generalization of the no-loss gambling method). We systematically compare the results obtained with these three rules to the theoretical confidence levels that can be inferred from performance in the perceptual task using Signal Detection Theory (SDT). We find that the MP provides better results in that respect. We conclude that MP is particularly well suited for studies of confidence that use SDT as a theoretical framework.

Editorial of "International Journal of Critical Indigenous Studies Volume 2, Number 1, 2009"

Over the past two decades neo liberalism has shaped global economic activity. The international reach of the current economic crisis propelled by the subprime mortgage meltdown in the United States has affected Indigenous communities in different ways to those whose investments were depleted by the Wall Street activities of an unregulated corporate and banking sector. Throughout this roller coaster economic ride the low socio-economic position of Indigenous peoples continued in Canada, the United States of America, New Zealand, Hawaii and Australia. The logic, or illogic of capital, failed to extend the boom of the economic upturn to Indigenous peoples, but is poised to extend the repercussions of the current downturn deep into Indigenous lives. The consistency of the Indigenous socio-economic position across these countries, even where treaties exist, indicates that the phenomenon is based on a shared Indigenous reality. In this special edition, the commonality in the way in which Indigenous people are engaged in and positioned by market forces and regulation by their respective nation states is proposed as one of the foundation plates of that Indigenous positioning...

Customer Energy in Relationships

All companies have a portfolio of customer relationships. From a managerial standpoint the value of these customer relationships is a key issue. The aim of the paper is to introduce a conceptual framework for customers’ energy towards a service provider. Customer energy is defined as the cognitive, affective and behavioural effort a customer puts into the purchase of an offering. It is based on two dimensions: life theme involvement and relationship commitment. Data from a survey study of 425 customers of an online gambling site was combined with data about their individual purchases and activity. Analysis showed that involvement and commitment influence both customer behaviour and attitudes. Customer involvement was found to be strongly related to overall spending within a consumption area, whereas relationship commitment is a better predictor of the amount of money spent at a particular company. Dividing the customers into four different involvement / commitment segments revealed differences in churn rates, word-of-mouth, brand attitude, switching propensity and the use of the service for socializing. The framework provides a tool for customer management by revealing differences in fundamental drivers of customer behaviour resulting in completely new customer portfolios. Knowledge of customer energy allows companies to manage their communication and offering development better and provides insight into the risk of losing a customer.

Elämänmuutoksen, jännityksen ja asiantuntijuuden representointi Veikkaus Oy:n mainonnassa vuosina 1970— 2006

Aim of this master's thesis paper for consumer economics, is to research gambling advertisements in Finland over a period of 35 years, from 1970 to 2006. Veikkaus Oy (later Veikkaus), was founded in 1940, as one of the three licensed gambling organizations in Finland. Material for the current research comprised 1494 advertisements published by Veikkaus in newspapers and magazines at that time. Veikkaus has the exclusive licence to organize lotto games, sport games, instant games and other draw games in Finland. The other two operators, The Finnish Slot Machine Association RAY and Fintoto (on-track horse betting), were not included in the current analysis. This study has been completed according to research contract and grand by the Finnish Foundation for Gaming Research (Pelitoiminnan tutkimussäätiö). In general, advertisements reflect surrounding culture and time, and their message is built on stratified meanings, symbols and codes. Advertising draws the viewer's attention, introduces the advertised subject, and finally, affects the individual's consumption habits. However, advertisements not only work on individual level, but also influence public perception of the advertised product. Firstly, in order to assess gambling as a phenomenon, this paper discusses gambling as consumer behaviour, and also reviews history of gambling in Finland. Winning is a major feature of gambling, and dreaming about positive change of life is a centre of most gambling ads. However, perceived excitement through risk of losing can also be featured in gambling ads. Secondly, this study utilizes Veikkaus’ large advertising archives, were advertising data is analyzed by content analysis and the semiotic analysis. Two methods have been employed to support analyzing outcome in a synergistic way. Content analysis helps to achieve accuracy and comprehensiveness. Semiotic analysis allows deeper and more sensitive analysis to emerged findings and occurrences. It is important to understand the advertised product, as advertising is bound to the culture and time. Hence, to analyze advertising, it is important to understand the environment where the ads appear. Content analysis of Veikkaus data discovered the main gambling and principal advertisement style for each.period. Interestingly, nearly half of Veikkaus’ advertisements promoted topic other than “just winning the bet”. Games of change, like Lotto, typically advertised indirectly represented dreams about winning. In the category of skill gambling, features were represented as investment, and the excitement of sporting expertise was emphasized. In addition, there were a number of gambling ads that emphasize social responsibility of Veikkaus as a government guided organization. Semiotic methods were employed to further elaborate on findings of content analysis. Dreaming in the advertisements was represented by the product of symbols, (e.g. cars and homes) that were found to have significance connection with each other. Thus, advertising represents change of life obtained by the winning. Interestingly, gambling ads promoting jackpots were often representing religious symbolisms. Ads promoting social responsibility were found to be the most common during economical depression of the 90’s. Deeper analysis showed that at that time, advertisements frequently represented depression-related meanings, such as unemployment and bank loans. Skill gaming ads were often represented by sports expertise – late 90’s, their number started sky rocketing, and continued increasing until 2006 (when this study ended). One may conclude that sport betting draws its meanings from the relevant consumer culture, and from the rules and features of the betted sport.

Ditos populares em músicas do cancioneiro popular: uma abordagem cognitiva

Nesta dissertação, analisam-se alguns ditos populares retomados em músicas do cancioneiro popular, com base na teoria da metáfora conceptual (Lakoff e Jonhson, 1980; Kövecses, 2002), e na teoria da integração conceptual (Fauconnier e Turner, 2002). Busca se investigar se a projeção metafórica presente no dito empregado em situações cotidianas se sustenta, quando o mesmo é retomado em uma letra de música. Este estudo encontra sua justificativa em uma das assunções basilares da linguística cognitiva de que as metáforas conceptuais estão presentes tanto nas conversas cotidianas quanto nas manifestações literárias e artísticas. Pretende se, assim, observar a multidirecionalidade dos processos de significação desse tipo de construção linguística, a fim de postular seu poder projetivo e metafórico na mente dos falantes. Dentro do repertório de construções proverbiais em português, é perceptível a construção proverbial condicional com a configuração sintático semântica [x P Q], entre as quais foi escolhida como objeto de estudo a configuração [Quem P Q]. A escolha das músicas foi aleatória, já que não se buscou um gênero ou estilo específico, mas canções que possuíssem ditos populares em suas letras. Na análise, de cunho interpretativo, procedeu-se a identificação do papel da metáfora conceptual presente no dito empregado em situações cotidianas e nas 10 músicas selecionadas para este estudo. Em seguida, postularam-se redes de integração conceptual subjacente ao sentido dos ditos nas interações em geral e nas músicas, de modo a explicar que as diferenças de sentido observadas ou não nos ditos transpostos para letras de músicas estão relacionadas ao tipo de rede de integração conceptual ativado durante o processo de mesclagem. As redes de integração postuladas para explicar a construção de sentido dos ditos e destes nas músicas analisadas, revelam compressões das relações de CAUSA EFEITO, MUDANÇA, IDENTIDADE, ANALOGIA DESANALOGIA e TEMPO, devido, sobretudo, ao papel que os ditos desempenham ao ilustrar cenas da vida das pessoas. Entre as metáforas que estruturam os ditos, nas interações e nas músicas, encontram-se A VIDA É UMA VIAGEM / A VIDA É UM TRAJETO QUE DEVE SER PERCORRIDO COM CAUTELA / VIDA É UM JOGO DE AZAR; TEMPO É LOCAL PARA ONDE ALGO SE DESLOCA; DIFICULDADES SÃO IMPEDIMENTOS (IN) TRANSPONÍVEIS; RELIGIÃO É UMA TRANSAÇÃO COMERCIAL; MORAL É UM OBJETO PRECIOSO (MAS FRÁGIL COMO O VIDRO); EXAGEROS SÃO GOLPES INCERTOS. Espera-se que a hipótese aventada com este estudo motive outras pesquisas sob o escopo teórico da Linguística Cognitiva; em especial, as teorias da metáfora e da mesclagem conceptual, as quais revelaram um potencial descritivo promissor para análise de fenômenos semântico-pragmáticos da língua portuguesa, como os ditos populares, construções situadas no topo da escala de idiomaticidade

Entre crânios analógicos e imagens digitais: alguns antecedentes históricos e culturais das tecnologias de neuro-imageamento

Nos últimos anos, temos nos deparado com a difusão maciça e a popularização crescente de descrições biológicas para aspectos outrora pensados como mentais, sociais, ou relacionais. Visível em diversas arenas leigas e científicas, esta tendência freqüentemente elege o cérebro como o órgão privilegiado da sua atenção. A cada semana é divulgada uma nova localização cerebral correlacionada os mais variados aspectos comportamentais e ou de personalidade. Acompanhando este movimento, é notável o esforço intelectual e financeiro despendido nos últimos anos no campo da saúde mental, no sentido de fazer avançar pesquisas cujo foco central é a descoberta das bases neurobiológicas dos transtornos mentais. Esta tendência apontaria na direção de uma fusão entre a psiquiatria e a neurologia em uma disciplina única, de teor fisicalista, chamada por alguns de cerebrologia. Dentre os acontecimentos que serviram de alicerce para a legitimação e a popularização desta tendência, o desenvolvimento nas últimas décadas de novas técnicas e tecnologias de visualização médica, como a tomografia por emissão de pósitrons (PET scan) e a ressonância magnética funcional (fMRI), foi fundamental. Elas permitiram a construção de imagens das mais diversas categorias nosográficas construídas no campo psiquiátrico, veiculando tacitamente uma série de pressupostos e promessas. Malgrado o imaginário cultural sustentado por estas tecnologias e todo o esforço despendido nas últimas décadas no sentido de se tentar localizar os marcadores biológicos dos transtornos psiquiátricos, não há, até o presente momento, nenhum resultado conclusivo que autorize o diagnóstico por imagem de nosografias como a esquizofrenia, a depressão, e muito menos o jogo patológico. Apesar de todo o alarde midiático e dos montantes milionários direcionados para pesquisas nesta área, os resultados concretos obtidos até agora não estão livres das mais ferozes controvérsias. Entretanto, ainda que estejamos muito longe da construção de mapas precisos para as perturbações mentais é espantoso o poder de convencimento que as neuro-imagens comportam na atualidade. Os scans são exibidos como verdades visuais, ou fatos acerca das pessoas e do mundo, numa proporção muito superior aos dados que apresentam. Alguns críticos chamam este aspecto de neurorealismo, ou de retórica da auto-evidência. A intenção deste trabalho é problematizar o poder persuasivo que as neuro-imagens detém na contemporaneidade, especialmente quando utilizadas com a finalidade diagnóstica no campo da saúde mental. Se estas imagens transmitem uma ideia de neutralidade, transparência imediata e auto-evidência, este trabalho almeja inseri-las num contexto sócio-histórico, a partir do qual puderam adquirir sentido, familiaridade e valor de verdade. O ponto de partida é o de que elas estão localizadas no cruzamento de dois movimentos históricos distintos: o das ilustrações médicas, em sua relação com a produção de conhecimento objetivo; e o das pesquisas acerca da localização no córtex cerebral de comportamentos complexos e traços de personalidade. Além de estabelecer algumas condições históricas de possibilidade para a emergência de um neo-localizacionismo cerebral, mediado pelas novas tecnologias de imageamento, pretende-se enfatizar algumas descontinuidades com projetos anteriores e marcar a influência do contexto cultural da atualidade para o sucesso e poder persuasivo deste tipo de tecnologia.

Insula and striatum mediate the default bias.

Humans are creatures of routine and habit. When faced with situations in which a default option is available, people show a consistent tendency to stick with the default. Why this occurs is unclear. To elucidate its neural basis, we used a novel gambling task in conjunction with functional magnetic resonance imaging. Behavioral results revealed that participants were more likely to choose the default card and felt enhanced emotional responses to outcomes after making the decision to switch. We show that increased tendency to switch away from the default during the decision phase was associated with decreased activity in the anterior insula; activation in this same area in reaction to "switching away from the default and losing" was positively related with experienced frustration. In contrast, decisions to choose the default engaged the ventral striatum, the same reward area as seen in winning. Our findings highlight aversive processes in the insula as underlying the default bias and suggest that choosing the default may be rewarding in itself.

A genetically mediated bias in decision making driven by failure of amygdala control.

Genetic variation at the serotonin transporter-linked polymorphic region (5-HTTLPR) is associated with altered amygdala reactivity and lack of prefrontal regulatory control. Similar regions mediate decision-making biases driven by contextual cues and ambiguity, for example the "framing effect." We hypothesized that individuals hemozygous for the short (s) allele at the 5-HTTLPR would be more susceptible to framing. Participants, selected as homozygous for either the long (la) or s allele, performed a decision-making task where they made choices between receiving an amount of money for certain and taking a gamble. A strong bias was evident toward choosing the certain option when the option was phrased in terms of gains and toward gambling when the decision was phrased in terms of losses (the frame effect). Critically, this bias was significantly greater in the ss group compared with the lala group. In simultaneously acquired functional magnetic resonance imaging data, the ss group showed greater amygdala during choices made in accord, compared with those made counter to the frame, an effect not seen in the lala group. These differences were also mirrored by differences in anterior cingulate-amygdala coupling between the genotype groups during decision making. Specifically, lala participants showed increased coupling during choices made counter to, relative to those made in accord with, the frame, with no such effect evident in ss participants. These data suggest that genetically mediated differences in prefrontal-amygdala interactions underpin interindividual differences in economic decision making.

Blocking central opiate function modulates hedonic impact and anterior cingulate response to rewards and losses.

Reward processing is linked to specific neuromodulatory systems with a dopaminergic contribution to reward learning and motivational drive being well established. Neuromodulatory influences on hedonic responses to actual receipt of reward, or punishment, referred to as experienced utility are less well characterized, although a link to the endogenous opioid system is suggested. Here, in a combined functional magnetic resonance imaging-psychopharmacological investigation, we used naloxone to block central opioid function while subjects performed a gambling task associated with rewards and losses of different magnitudes, in which the mean expected value was always zero. A graded influence of naloxone on reward outcome was evident in an attenuation of pleasure ratings for larger reward outcomes, an effect mirrored in attenuation of brain activity to increasing reward magnitude in rostral anterior cingulate cortex. A more striking effect was seen for losses such that under naloxone all levels of negative outcome were rated as more unpleasant. This hedonic effect was associated with enhanced activity in anterior insula and caudal anterior cingulate cortex, areas implicated in aversive processing. Our data indicate that a central opioid system contributes to both reward and loss processing in humans and directly modulates the hedonic experience of outcomes.

Cortical substrates for exploratory decisions in humans.

Decision making in an uncertain environment poses a conflict between the opposing demands of gathering and exploiting information. In a classic illustration of this 'exploration-exploitation' dilemma, a gambler choosing between multiple slot machines balances the desire to select what seems, on the basis of accumulated experience, the richest option, against the desire to choose a less familiar option that might turn out more advantageous (and thereby provide information for improving future decisions). Far from representing idle curiosity, such exploration is often critical for organisms to discover how best to harvest resources such as food and water. In appetitive choice, substantial experimental evidence, underpinned by computational reinforcement learning (RL) theory, indicates that a dopaminergic, striatal and medial prefrontal network mediates learning to exploit. In contrast, although exploration has been well studied from both theoretical and ethological perspectives, its neural substrates are much less clear. Here we show, in a gambling task, that human subjects' choices can be characterized by a computationally well-regarded strategy for addressing the explore/exploit dilemma. Furthermore, using this characterization to classify decisions as exploratory or exploitative, we employ functional magnetic resonance imaging to show that the frontopolar cortex and intraparietal sulcus are preferentially active during exploratory decisions. In contrast, regions of striatum and ventromedial prefrontal cortex exhibit activity characteristic of an involvement in value-based exploitative decision making. The results suggest a model of action selection under uncertainty that involves switching between exploratory and exploitative behavioural modes, and provide a computationally precise characterization of the contribution of key decision-related brain systems to each of these functions.

从赌博游戏中的损失厌恶行为看情感预测与体验在决策中的作用

In Kermer, Driver-Linn, Wilson and Gilbert’s (2006) study on affective forecast, they found that people have a tendency to overestimate affective reactions in gains and losses, and people expect losses to have greater hedonic impact than gains of equal magnitude. Because of thus affective forecasting error, people prefer to irrationally avoid losses. Loss aversion is then seen as both a wealth-maximizing error and an affect-maximizing error. The present study examined the relationships among affective forecast, affective experience and loss aversion, and tested Kermer et al.’s (2006) conclusion that people’s loss aversion is an affective forecasting error. In experiment 1, we examined the relationship between affective forecast and loss aversion. Kermer et al.’s (2006) hypothesized that when people expect losses to have greater hedonic impact than gains, they will accept the gambling task, and when people expect gains to have greater hedonic impact than losses, they will refuse the gambling task. We found that (1) individuals with lower loss aversion had a greater tendency to accept a gambling task than those with higher loss aversion; (2) individuals with lower loss aversion expected losses and gains to have smaller affective impacts than those with higher loss aversion. Thus, people never exactly calculated their forecasting affective. In experiment 2, we examined the relationship between affective forecast and affective experience. Consistent with Kermer et al.’s (2006) finding, we found that our participants tended to overestimate affective reactions in gains as well as losses. More interestingly, Kermer et al.’s (2006) found that participants’ predictions for a loss were significantly more distant from experienced emotions than were their predictions for a win, we, however, found the opposite —participants’ predictions for a win were significantly more distant from the experienced emotions than were their predictions for a loss. These experiments further validated the relations between affection and decision making, and contributed to our understanding on the affective reactions to future events. Our study imply that it was not the exact calculation of affective forecast on decision outcomes, but rather the magnitude of affection on outcomes, that influenced people’s affective decision making. It indicated that those with lower magnitude of affection would less like to avoid losses, and thus more like to accept a gambling task.
