Perceptions and reality: Economic voting at the 2004 European Parliament elections

One of the most influential explanations of voting behaviour is based on economic factors: when the economy is doing well, voters reward the incumbent government and when the economy is doing badly, voters punish the incumbent. This reward-punishment model is thought to be particularly appropriate at second order contests such as European Parliament elections. Yet operationalising this economic voting model using citizens' perceptions of economic performance may suffer from endogeneity problems if citizens' perceptions are in fact a function of their party preferences rather than being a cause of their party preferences. Thus, this article models a 'strict' version of economic voting in which they purge citizens' economic perceptions of partisan effects and only use as a predictor of voting that portion of citizens' economic perceptions that is caused by the real world economy. Using data on voting at the 2004 European Parliament elections for 23 European Union electorates, the article finds some, but limited, evidence for economic voting that is dependent on both voter sophistication and clarity of responsibility for the economy within any country. First, only politically sophisticated voters' subjective economic assessments are in fact grounded in economic reality. Second, the portion of subjective economic assessments that is a function of the real world economy is a significant predictor of voting only in single party government contexts where there can be a clear attribution of responsibility. For coalition government contexts, the article finds essentially no impact of the real economy via economic perceptions on vote choice, at least at European Parliament elections.

Imperfect assessment and limited information preclude optimal strategies in male-male fights in the orb-weaving spider Metellina mengei

Agonistic behaviour between male orb-web spiders Metellina mengei competing for access to female webs was examined in field experiments to test the major predictions of game theory. Winners of fights were significantly larger than losers, particularly with respect to the length of the first pair of legs, which are sexually dimorphic in this species and used extensively in agonistic encounters. The size of the winning male had no influence on contest intensity or duration, and neither did relative size. However, fight intensity and duration were both positively correlated with the size of the losing male. Resident males won significantly more contests than intruders. Winning intruders were significantly larger than winning residents and it was these winning intruders that tended to produce the longer fights. Female weight and hence reproductive value had a marked influence on fight intensity and duration of fights won by the intruder but not those won by the resident. This indicates that only the resident obtains information about the female. These data are discussed with reference to the discrepancy with theory and a failure of some contestants to obtain information on resource value and relative contestant size necessary to optimize fight strategy.

Signal residuals and hermit crab displays: flaunt it if you have it!

In animal contests selection should favour information gathering regarding the likely costs and benefits of continued conflict, and displays may provide a means for contestants to gain information about the fighting ability or aggressive intent of competitors. However, there is debate over the reliability of such displays and low levels of deception may occur within otherwise honest signalling systems. Hermit crabs use displays involving the chelipeds during agonistic encounters. We examined how variation in chelae size in relation to body size, a determinant of fighting ability, affects their use in displays and the process and outcome of contests over gastropod shells. In accordance with deceptive use of an otherwise honest signal, we found that contestants with large chelipeds for their body size spent more time performing the cheliped presentation display. Moreover, cheliped residuals and displays influenced the escalation level of encounters. There was a positive association between cheliped displays and the occurrence of 'grappling', but a negative association between displays and the occurrence of shell fights, suggesting that displays may signal aggressive intent and a reluctance to back off or accept the more passive defender role in a fight. Furthermore, the smaller of the two contestants in shell fights had larger cheliped residuals compared to those smaller contestants not involved in shell fights, which is consistent with disrupted opponent assessment. This study adds to mounting evidence that when acting as a signaller, individuals for whom the display exaggerates competitive ability attempt to manipulate opponents, using the display more often.

Gender differences in aggressive behaviour in convict cichlids

Males and females of many species engage in agonistic encounters. However, differing selection pressures on each sex are predicted to result in sex differences in aggressive behaviour during contests. Comparing male and female intrasexual contests can yield intriguing differences, shedding light on the forces shaping the use of particular aggressive tactics. We investigated whether fundamental gender-related differences in aggression, not explained by current parental role, are present in convict cichlids, Amatitlania nigrofasciata. Intrasexual agonistic encounters between isolated males and between isolated females not previously paired to a breeding partner were staged. Using this approach we first tested for behavioural differences between the sexes. Second, using a novel startle technique aimed at probing motivation to fight, we tested for gender-related differences in aggressive motivation. Third, we examined whether size, rather than gender, plays a role in determining the tactics used during contests. In addressing these aims we found: (1) females used more frontal display and biting, and spent more time in close proximity to their opponent, whereas males used more lateral display and tail beating than females during agonistic encounters; (2) there was no difference in the response of male or female convict cichlids to a startling stimulus aimed at probing motivation to fight; and (3) the addition of focal weight and length as possible covariates had no significant effect on the analyses. Possible causal and functional reasons for these gender-related differences in fight tactics are discussed. (C) 2009 The Association for the Study of Animal Behaviour. Published by Elsevier Ltd.

Large body size for winning and large swords for winning quickly in swordtail males, Xiphophorus helleri

Contestants can either assess their own resource-holding potential relative to their opponent (mutual assessment) or rely solely on the assessment of their own fighting ability (self-assessment). To discriminate between these possibilities, we staged dyadic territorial contests between 'size-matched' male swordtails. These contests consist of a combination of ritualized displays and direct fighting. Although size differences were small, winners were larger than losers and smaller fish tended to be winners only when the size difference was negligible. Body size, however, did not influence contest duration and there was no increase in contest duration with mean body size; thus, there is no support for self-assessment in these animals. We also examined the effects of the sword, which comprises a sexually selected extension used in female choice that reduces swimming efficiency but increases acceleration. The length of the sword (adjusted for body size) did not differ between winners and losers; however, losers conceded earlier if the opponent had a large sword for its body size but this decision was independent of the loser's own sword length. Losers thus assessed the swords of winners, which precludes self-assessment; however, because winners appeared not to assess the swords of losers, this does not fully support the idea of mutual assessment.

Policing the Globe: State Sovereignty and the International in the Post-9/11 Crime Novel

Two recent studies of 9/11 literature are dismissive of the contributions that crime and espionage novels have made to ongoing efforts to map the significance of 9/11 and its aftermath. My essay contests the assumption that only literary fiction – which pays sufficient attention to trauma – can “bear witness” to the events of 9/11 and argues that such fiction is, in fact, singularly ill-equipped to illuminate the complex geo-political circumstances that 9/11 entrenched and transformed. By contrast, genre novels by John Le Carré and Don Winslow have responded in imaginative and critical ways to post-9/11 and avowedly trans-national securitization initiatives and hence to efforts to trouble traditional accounts of state sovereignty.

The Representation of the Female Body in the Multimedia Works of Regina José Galindo

The female body is central to the performance art, poetry and blog site interventions of Guatemalan Regina José Galindo. While Galindo is best known for her performance work, this article compares the hereto overlooked, distinctive and often shocking representations of the female body across her multimedia outputs. We first consider the ways in which, in all three media, Galindo presents an ‘excessive’, carnivalised, grotesque and abject female body. Second, we analyse representations of the female body that has been subjected to violence at a private and public level. In so doing, we show how Galindo not only contests hegemonic visions of gender and (national) identity but also challenges the viewer/reader to engage with, rather than look away from, the violence to which women are subjected in patriarchal society.

The shifting engines of medicalization

Social scientists and other analysts have written about medicalization since at least the 1970s. Most of these studies depict the medical profession, interprofessional or organizational contests, or social movements and interest groups as the prime movers toward medicalization. This article contends that changes in medicine in the past two decades are altering the medicalization process. Using several case examples, I argue that three major changes in medical knowledge and organization have engendered an important shift in the engines that drive medicalization: biotechnology (especially the pharmaceutical industry and genetics), consumers, and managed care. Doctors are still gatekeepers for medical treatment, but their role has become more subordinate in the expansion or contraction of medicalization. Medicalization is now more driven by commercial and market interests than by professional claims-makers. The definitional center of medicalization remains constant, but the availability of new pharmaceutical and potential genetic treatments are increasingly drivers for new medical categories. This requires a shift in the sociological focus examining medicalization for the twenty-first century.

Making space for tourists with minority languages::the case of Belfast’s Gaeltacht Quarter

This article examines the role of tourism as a motive and mechanism for change in contemporary cities, considering how the theming of space with tourists in mind necessarily involves other kinds of spatial and social transformation, and asking what role actual and hypothetical tourists play in local contests over space and representation. Looking closely at Belfast’s Gaeltacht Quarter provides an insight into how global fashions in place marketing, tourism and minority language promotion intersect with the particularities of areas to which they are applied. This paper argues that the superficially value-neutral, internationally recognisable language of economic
development can be used both as a means of transcending, and a means of
strategically negotiating, intense struggles over space, identity and status.

Understanding how animals fight with Lloyd Morgan's canon

Various game theory models have been used to explain animal contests. Here we attend to the presumed cognitive abilities required by these models with respect to information gathering and consequent decision making. Some, such as the hawk/dove game and self-assessment models require very limited cognitive ability. By contrast, the broadly accepted sequential assessment model requires that contestants know their own abilities and compare them with information gathered about their opponent to determine which has the greater resource-holding power. However, evidence for assessment of relative abilities is sparse and we suggest that this complex ability is probably beyond most animals. Indeed, perceptual limitations may restrict information about an individual's own displays and thus preclude comparison. We take a parsimonious view and conclude that simple summation of causal factors accounts for changes in fight motivation without requiring mutual evaluation of relative abilities. © 2012 The Association for the Study of Animal Behaviour.

Do mirrors reflect reality in agonistic encounters? A test of mutual cooperation in displays

Animals frequently engage in mutual displays that may allow or at least help decisions about the outcome of agonistic encounters with mutual benefit to the opponents. In fish these often involve lateral displays, with previous studies finding evidence of population-level lateralization with a marked preference for showing the right side and using the right eye. Because both opponents tend to show this preference a head to tail configuration is formed and is used extensively during the display phase. Here we tested the significance of these lateral displays by comparing displays to a mirror with those to a real opponent behind a transparent barrier. The frequency of displays was lower to a mirror but the individual displays were of greater duration indicating a slower pace of the interaction with a mirror. This suggests that fish respond to initiatives of real opponents but as mirror images do not initiate moves the focal fish only moves when it is ready to change position. However, lateralization was still found with mirrors, indicating that the right-side bias is a feature of the individual and not of the interaction between opponents. We discuss implications for ideas about the evolution of mutual cooperation and information exchange in contests, as well as the utility of the use of mirrors in the study of aggression in fish.

City Profile: Erbil

Erbil (Hawler in Kurdish), is the capital and the largest city of Iraqi Kurdistan. Having been continuously inhabited for about 6000 years, the city has recently been regarded by UNESCO World Heritage as one of the world’s oldest urban settlements. The city is witnessing remarkable urban growth and rapid spatial expansion compounded by a dramatic increase in population due to emigration from the countryside and rural areas over the last three decades. Following the changing geopolitical landscape of post-war Iraq, urban changes and socio-political transformation are largely driven by Erbil’s growing autonomous status as the capital of northern region of Kurdistan since 2003. This paper explores the layers of historical, spatial and social developments of the contemporary urban context of Kurdistan in general and of Erbil in particular as a reflection of the changing status of the city, as well as the polarization of Iraq and the emergence of neoliberal urbanism. The tension between the global and modern from one side and traditional and authentic from another is ever present and evident in everyday challenges in the planning of the city. In large part, Erbil’s built fabric embodies the dichotomy of identity and contests between its past and future, in which the present remains a transition between two disconnected realities.

Aggressiveness as a component of fighting ability in pigs using a game-theoretical framework

Understanding animal contests has benefited greatly from employing the concept of fighting ability, termed resource-holding potential (RHP), with body size/weight typically used as a proxy. However, victory does not always go to the larger/heavier contestant and the existing RHP approach thereby fails to accurately predict contest outcome. Aggressiveness, typically studied as a personality trait, might explain part of this discrepancy. We investigated whether aggressiveness forms a component of RHP, examining effects on contest outcome, duration and phases, plus physiological measures of costs (lactate and glucose). Furthermore, using the correct theoretical framework, we provide the first study to investigate whether individuals gather and use information on aggressiveness as part of an assessment strategy. Pigs, Sus scrofa, were assessed for aggressiveness in resident-intruder tests whereby attack latency reflects aggressiveness. Contests were then staged between size-matched animals diverging in aggressiveness. Individuals with a short attack latency in the resident-intruder test almost always initiated the first bite and fight in the subsequent contest. However, aggressiveness had no direct effect on contest outcome, whereas bite initiation did lead to winning in contests without an escalated fight. This indirect effect suggests that aggressiveness is not a component of RHP, but rather reflects a signal of intent. Winner and loser aggressiveness did not affect contest duration or its separate phases, suggesting aggressiveness is not part of an assessment strategy. A greater asymmetry in aggressiveness prolonged contest duration and the duration of displaying, which is in a direction contrary to assessment models based on morphological traits. Blood lactate and glucose increased with contest duration and peaked during escalated fights, highlighting the utility of physiological measures as proxies for fight cost. Integrating personality traits into the study of contest behaviour, as illustrated here, will enhance our understanding of the subtleties of agonistic interactions.

Parades, Flags, Carnivals and Riots: Public Space, Contestation and Transformation in Northern Ireland

This paper explores one of the defining aspects of politics and identity in Northern Ireland: the control and utilization of public space, particularly urban public space. Ethnopolitical conflict consistently reveals itself through contestation over public space. The role of ritual events is important in the development of political identity and group cohesion. The symbolic landscape will be constructed through displays of identity by dominant groups and their ability to control that landscape by inhibiting displays by other groups. This will reveal itself through frequent contests over rituals and symbols. This paper looks at the role of ritual events in civic spaces in Belfast but particularly asks what role they might play in conflict transformation. The 1998 agreement offered political structures that provided for shared power after 30 years of violent conflict. At the same time, there was an increase in contestation over public space as political groups within the previously marginalized Catholic community demanded recognition within the public sphere and a rebalancing of the public space through changes to the previously dominant Protestant and Unionist expression of identity. The paper concludes by suggesting that in “shared space” a new civic identity that spans the political and ethnic divisions has started to develop in Belfast and that this might evolve despite an increased residential division throughout the urban area.

To breathe or fight? Siamese fighting fish differ when facing a real opponent or mirror image

Displays are a feature of animal contest behaviour and have been interpreted as a means of gathering information on opponent fighting ability, as well as signalling aggressive motivation. In fish, contest displays often include frontal and lateral elements, which in the latter involves contestants showing their flanks to an opponent. Previous work in a range of fish species has demonstrated population-level lateralization of these displays, preferentially showing one side to their opponent. Mirrors are commonly used in place of a real opponent to study aggression in fish, yet they may disrupt the normal pattern of display behaviour. Here, using Siamese fighting fish, Betta splendens, we compare the aggressive behaviour of males to a mirror image and real opponent behind a transparent barrier. As this species is a facultative air-breather, we also quantify surface breathing, providing insights into underlying fight motivation. Consistent with previous work, we found evidence of population-level lateralization, with a bias to present the left side and use the left eye when facing a real opponent. Contrary to expectations, there were no differences in the aggressive displays to a mirror and real opponent, with positive correlations between the behaviour in the two scenarios. However, there were important differences in surface breathing, which was more frequent and of longer duration in the mirror treatment. The reasons for these differences are discussed in relation to the repertoire of contest behaviour and motivation when facing a real opponent.
