Physiological Responses to Near-Miss Outcomes and Personal Control During Simulated Gambling

Near-miss outcomes during gambling are non-win outcomes that fall close to a pay-out. While objectively equivalent to an outright miss, near-misses motivate ongoing play and may therefore be implicated in the development of disordered gambling. Given naturalistic data showing increases in heart rate (HR) and electrodermal activity (EDA) during periods of real gambling play, we sought to explore the phasic impact of win, near-miss and full-miss outcomes on physiological arousal in a controlled laboratory environment. EDA and HR were monitored as healthy, student participants (n = 33) played a simulated slot-machine task involving unpredictable monetary wins. A second gambling distortion, perceived personal control, was manipulated within the same task by allowing the participant to select the play icon on some trials, and having the computer automatically select the play icon on other trials. Near-misses were rated as less pleasant than full-misses. However, on trials that involved personal choice, near-misses produced higher ratings of ‘continue to play’ than full-misses. Winning outcomes were associated with phasic EDA responses that did not vary with personal choice. Compared to full-misses, near-miss outcomes also elicited an EDA increase, which was greater on personal choice trials. Near-misses were also associated with greater HR acceleration than other outcomes. Near-miss outcomes are capable of eliciting phasic changes in physiological arousal consistent with a state of subjective excitement, despite their objective non-win status.     

A transient presence: black visitors and sojourners in Imperial Germany, 1884–1914

The onset of German colonial rule in Africa brought increasing numbers of black men and women to Germany. Pre-1914 the vast majority of these Africans can best be described as visitors or sojourners and the black population as a whole was a transient one. This makes recovering their presence in the archival record exceptionally difficult and it is not surprising that the existing historiography is dominated by biographies of well-documented lives. Through utilising a number of recently digitised archival materials, particularly the Hamburg Passenger Lists, this article draws upon a database with information on 1094 individuals from sub-Saharan Africa who spent time in Germany over the period 1884–1914 in order to widen our understanding of the black presence as a whole. It offers new insights and detail into the composition and character of this fluid population – where visitors came from, why they came to Germany, their age on arrival – as well as more accurate information on the temporal and spatial distribution of African visitors.     

Evaluation of trace evidence in the form of multivariate data

Summary.  The evaluation of measurements on characteristics of trace evidence found at a crime scene and on a suspect is an important part of forensic science. Five methods of assessment for the value of the evidence for multivariate data are described. Two are based on significance tests and three on the evaluation of likelihood ratios. The likelihood ratio which compares the probability of the measurements on the evidence assuming a common source for the crime scene and suspect evidence with the probability of the measurements on the evidence assuming different sources for the crime scene and suspect evidence is a well-documented measure of the value of the evidence. One of the likelihood ratio approaches transforms the data to a univariate projection based on the first principal component. The other two versions of the likelihood ratio for multivariate data account for correlation among the variables and for two levels of variation: that between sources and that within sources. One version assumes that between-source variability is modelled by a multivariate normal distribution; the other version models the variability with a multivariate kernel density estimate. Results are compared from the analysis of measurements on the elemental composition of glass.     

“The Vital Force”: Visuality and the National Economy

Although it has often been conceived as a material or already‐existing kind of category, the “economy”, before it can be governed, must first be “made up” and constituted in particular ways. This paper seeks to contribute to recent genealogies of the “economy” by highlighting the role of one particular “cultural” technology–the techniques of visuality–in the making up of the national economy during the interwar and postwar periods. To develop this analysis, this paper reviews the ways in which private and public financial initiatives turned to visuality and advertising as a way to appeal more directly to and mobilize working class and everyday populations. In these appeals to “popular finance” visual techniques were used to diagram both a reworked conception of the national economy as well as the modes of citizenship key to this rationality of national economic space. This case also helps underscore the heterogeneity with which the national economy was assembled as a mode of economic governance constituted in multiple and never‐completed kinds of ways. Highlighting this heterogeneity, this paper concludes, is important especially in the context of discussions of “globalization” which are, once again, provoking questions relating to the very making of economic space, practice and identity.     

Dual effects of ‘losses disguised as wins’ and near-misses in a slot machine game

Individually, both near-misses and losses disguised as wins (LDWs) have been seen to exert pro-motivational effects on gambling. However, it is not clear whether both structural characteristics are effective within the same game. Participants (n = 40) played a slot machine simulation. The simulation delivered near-misses, wins and ‘full-misses’. Half the participants also received LDWs that occurred independently of the outcomes on the payline. Valence and motivation ratings were collected after each round. Results showed that the LDW group reported increased valence ratings compared to the no-LDW group. Within the LDW group, trials with LDWs also resulted in increased enjoyment compared to trials without LDWs. We distinguished near-misses falling either side of the payline. Near-misses before the payline (NMB) were rated as more motivational than near-misses after the payline (NMA), whereas NMAs were rated as more aversive than NMBs. These differences between the two near-miss types were exacerbated by LDWs. Results demonstrate LDWs increase the trial-by-trial enjoyment of non-win outcomes. The motivational and hedonic effects of near-misses differed for events either side of the payline, and these differences were exaggerated by the presence of LDWs. Thus, near-misses can retain their effectiveness in complex forms of gambling that also deliver LDWs.     

Sampling issues in the administration of justice

Colin Aitken first became interested in sampling in the context of the administration of justice when the case of US versus Shonubi was brought to his attention. Shonubi was a Nigerian working in New York. He was arrested at Kennedy Airport when seen behaving in a suspicious manner in the baggage hall, having returned on a flight from Nigeria. He was found to have 103 bags of a white substance inside him, four of which were examined. The white substance was identified as heroin. Shonubi was arrested, tried and found guilty of drug smuggling. The question then arose as to the length of sentence he should be given.     

Turn it around: short-term management for aggression and anger

1. Although nurses are at considerable risk for assaults, there are few practical and specific guidelines for controlling anger and aggression. 2. A training course was developed to give staff the necessary skills and knowledge to cope with clients who have the potential to become angry and assaultive, or those who have already become violent. 3. Participants in the training course felt more confident in managing potentially violent situations, and they reported relying on methods to de-escalate the situation to halt a sequence that would ultimately lead to violence.     

Performing the limits of finance

Recent financial turmoil has put emphasis once again on the very meaning and reach of ‘finance’. In doing so, recent financial crises have also provoked questions about the very ‘ends’ of finance: Where are the borders of finance? Given the expansive reach of financial innovation over the past two decades, are there any serious limits to the kinds of practices that can be converted into financial objects? Does the culture of finance (expansive and all encompassing) encounter meaningful interruptions? This paper explores these questions by reviewing a cluster of public-art responses to the 2008 financial crisis mounted by artists critical of the expansive logic of financial abstraction. This paper pays particular attention to the work of Fergal McCarthy and Fred Forest, two public artists who have confronted finance and its rational culture with practices of gameplay, whimsy, and carnival. In doing so, these artists invoke a strategy designed to lay the all-encompassing claims of financial abstraction alongside its own impossibility; alongside performances which undermine the expansive claims of financial abstraction. These are strategies, I conclude, which can interrupt the technocratic discourses which dominate the contemporary cultures of finance; strategies which, in the words of one artist, evoke ‘plausible states of uncertainty’ about our faith in financial abstraction.
