We present a model of bargaining in which a committee searches over the pol-icy space, successively amending the default by voting over proposals. Bargaining ends when proposers are unable or unwilling to amend the existing default,which is then implemented. Our main goal is to study the policies that can be implemented from any initial default in a pure-strategy stationary Markov perfect equilibrium for an interesting class of environments including multidimensional and infinite policy spaces. It is convenient to start by characterizing the set of immovable policies that are implemented, once reached as default. These policies form a weakly stable set and, conversely, any weakly stable set is supported by some equilibrium. Using these results, we show that minimum-winning coalitions may not form and that a player who does not propose may nevertheless earn all of the surplus from agreement. We then consider how equilibrium outcomes change as we vary the order in which players propose, the identity of proposers,and the set of winning coalitions. First, if the policy space is well ordered, then the committee implements the ideal policy of the last proposer in a subset of a weakly stable set, but this result does not generalize to other cases. We also show, surprisingly, that a player may prefer not to be given the opportunity to propose and that the set of immovable policies may shrink as the quota increases. Finally, we derive conditions under which immovable policies in semi-Markovian equilibria form a consistent choice set. [less ▲]

Il presente contributo intende riflettere criticamente sulle politiche europee di asilo a partire da un'analisi dell'approccio emergenziale che ha caratterizzato l'impegno del governo italiano in questo settore nell'ultimo decennio. In particolare, analizzando le conseguenze di tale approccio a partire in particolare dalla cosiddetta “emergenza nord-Africa” (ENA), intendo mettere in evidenza gli effetti perversi del Sistema europeo comune di asilo il quale sembra produrre tutt’altro rispetto all’auspicato spazio comune di protezione e solidarietà. Questi effetti perversi derivano dal fatto che il Sistema comune non soltanto si propone di garantire che ai richiedenti asilo, “indipendentemente dallo Stato membro in cui è presentata la domanda d’asilo, sia riservato un trattamento di livello equivalente quanto alle condizioni di accoglienza e di pari livello quanto alle disposizioni procedurali e alla determinazione dello status” (Consiglio Europeo 2010, p. 32); ma, soprattutto, aspira a “prevenire o ridurre i movimenti secondari all’interno dell’Unione” (Consiglio Europeo 2010, p. 32), così come è dimostrato dall’incondizionata fedeltà ai principi Dublino – ribaditi ancora una volta nel nuovo regolamento Dublino III (n. 604/2013 del 26 giugno 2013) – che ancorano il richiedente asilo al paese di primo ingresso. Cercherò quindi di evidenziare come la mancanza di programmazione, la costante carenza di posti nel sistema ordinario e il conseguente susseguirsi di azioni di accoglienza intraprese al di fuori di esso, si traducano in una cronicizzazione dell’emergenza (Olivieri 2011) e in un abbassamento generale del livello di accoglienza i cui effetti consistono nella riproduzione della dipendenza dei richiedenti asilo accolti nonché nell’incremento dei movimenti secondari tra stati membri con sempre più richiedenti e addirittura titolari di protezione che preferiscono vivere alla stregua di irregolari in altri paesi europei.

The employment structure undergoes constant change. Certain occupations grow while others decline under the pressure of technological advances, internationalization and welfare state reforms. This evolution at the aggregate level has been well documented. Our knowledge of how macro-level change in the employment structure is brought about through micro-level career adjustments is less extensive. Drawing on panel data, this paper examines the types of workers most likely to leave occupations that have declined over the past 20 years, and the most likely destination of these exits in Great Britain, Germany and Switzerland. Overall, we find that women are more likely than men to leave a declining occupation, and the most likely route out of declining occupations for female workers is towards low paid growing occupations. Clerical workers are more likely to exit to high paid growing occupations than production workers, and male production workers are at higher risk than female clerks of exiting into unemployment.

PURPOSE OF REVIEW: The notion that play may facilitate learning has long been touted. Here, we review how video game play may be leveraged for enhancing attentional control, allowing greater cognitive flexibility and learning and in turn new routes to better address developmental disorders. RECENT FINDINGS: Video games, initially developed for entertainment, appear to enhance the behavior in domains as varied as perception, attention, task switching, or mental rotation. This surprisingly wide transfer may be mediated by enhanced attentional control, allowing increased signal-to-noise ratio and thus more informed decisions. SUMMARY: The possibility of enhancing attentional control through targeted interventions, be it computerized training or self-regulation techniques, is now well established. Embedding such training in video game play is appealing, given the astounding amount of time spent by children and adults worldwide with this media. It holds the promise of increasing compliance in patients and motivation in school children, and of enhancing the use of positive impact games. Yet for all the promises, existing research indicates that not all games are created equal: a better understanding of the game play elements that foster attention and learning as well as of the strategies developed by the players is needed. Computational models from machine learning or developmental robotics provide a rich theoretical framework to develop this work further and address its impact on developmental disorders. [less ▲]

A briefly flashed target stimulus can become "invisible" when immediately followed by a mask-a phenomenon known as backward masking, which constitutes a major tool in the cognitive sciences. One form of backward masking is termed metacontrast masking. It is generally assumed that in metacontrast masking, the mask suppresses activity on which the conscious perception of the target relies. This assumption biases conclusions when masking is used as a tool-for example, to study the independence between perceptual detection and motor reaction. This is because other models can account for reduced perceptual performance without requiring suppression mechanisms. In this study, we used signal detection theory to test the suppression model against an alternative view of metacontrast masking, referred to as the summation model. This model claims that target- and mask-related activations fuse and that the difficulty in detecting the target results from the difficulty to discriminate this fused response from the response produced by the mask alone. Our data support this alternative view. This study is not a thorough investigation of metacontrast masking. Instead, we wanted to point out that when a different model is used to account for the reduced perceptual performance in metacontrast masking, there is no need to postulate a dissociation between perceptual and motor responses to account for the data. Metacontrast masking, as implemented in the Fehrer-Raab situation, therefore is not a valid method to assess perceptual-motor dissociations. [less ▲]

The left dorsolateral prefrontal cortex (ldlPFC) has been highlighted as a key actor in human perceptual decision-making (PDM): It is theorized to support decision-formation independently of stimulus type or motor response. PDM studies however generally confound stimulus onset and task onset: when the to-be-recognized stimulus is presented, subjects know that a stimulus is shown and can set up processing resources-even when they do not know which stimulus is shown. We hypothesized that the ldlPFC might be involved in task preparation rather than decision-formation. To test this, we asked participants to report whether sequences of noisy images contained a face or a house within an experimental design that decorrelates stimulus and task onset. Decision-related processes should yield a sustained response during the task, whereas preparation-related areas should yield transient responses at its beginning. The results show that the brain activation pattern at task onset is strikingly similar to that observed in previous PDM studies. In particular, they contradict the idea that ldlPFC forms an abstract decision and suggest instead that its activation reflects preparation for the upcoming task. We further investigated the role of the fusiform face areas and parahippocampal place areas which are thought to be face and house detectors, respectively, that feed their signals to higher level decision areas. The response patterns within these areas suggest that this interpretation is unlikely and that the decisions about the presence of a face or a house in a noisy image might instead already be computed within these areas without requiring higher-order areas.

Taking her cue from the contemporary interest in both life-writing and Victorian individuals, Steveker focuses on the genre of neo-Victorian fictional biography. Providing close readings of Adam Foulds’s The Quickening Maze (2009) and Richard Flanagan’s Wanting (2009), Steveker argues that these two novels not only undermine clichéd perceptions of the ‘eminent Victorians’ whose lives they depict, but also question the idealised image of the Victorian age as a period of confident humanism and individual self-respect. Making two Victorian authors return as neo-Victorian fictional characters, Foulds’s and Flanagan’s novels exemplify the desire of repetition which is symptomatic of the neo-Victorian project.

This essay takes its cue from Butler's notion of precariousness, delineated in her study Precarious Life: The Powers of Mourning and Violence (2004). But while Butler is concerned with the events of 9/11 as the US-American seminal catastrophe of the early twenty-first century, this essay focuses on fictional representations of WWI and WWII, the two wars which turned out to determine European and, indeed, World politics throughout the twentieth century. The novels discussed in this essay are examples of how fictional texts of both the twentieth and the twenty-first centuries are involved in critically (re)evaluating the British perspective on these two wars which can be described, each for its own particular cultural, political and ideological reasons, as having exposed the precariousness of human existence. Pat Barker's Regeneration trilogy (1991-1995) is engaged in demythologizing WWI as a 'great' war. A.L. Kennedy’s Day (2007) is concerned with undermining the notion of WWII as a 'just' war the British fought in defence of civilization and humanity. Each novel problematizes the damaging effects which the inhumane conditions of industrial warfare have on human psychic stability. Both Barker's trilogy and Kennedy's novel feature protagonists whose traumatic war experiences have caused them to develop split personalities; and it is with the help of these characters' mental instabilities that the texts negotiate the precarious consequences entailed in a self's complete loss of control and power over one's own well-being. Next to discussing each author's particular representational strategy of narrating her protagonist's split into self and internal other, the essay also analyses the different ideological agendas underlying Barker's and Kennedy's texts. As the essay shows, both writers' protagonists strive to reconcile self and internal other in order to reaffirm their identities. But while Kennedy's Day is indebted to liberal humanism in its celebration of 'high' art and its supposed unifying effects on human Selfhood, Barker's novels suggest a reconciliation of traumatized self and internal other which is best analysed through the lens of Levinasian ethics. The Regeneration trilogy, the essay argues, privileges a concept of dual, if not multiple selfhood by representing healing as the ethical acceptance of difference, not its repression or expulsion. Thus, Barker's novels defy the violence which, according to Levinas, comes from subjecting the other to the self's understanding. [less ▲]

The breadth and scale of multimedia archives provides a tremendous potential for historical research that hasn't been fully tapped up to know. In this paper we want to discuss the approach taken by the History of Europe application, a demonstrator for the integration of human and machine computation that combines the power of face recognition technology with two distinctively different crowd-sourcing approaches to compute co-occurrences of persons in historical image sets. These co-occurrences are turned into a social graph that connects persons with each other and positions them, through information about the date and location of recording, in time and space. The resulting visualization of the graph as well as analytical tools can help historians to find new impulses for research and to un-earth previously unknown relationships. As such the integration of human expertise and machine computation enables a new class of applications for the exploration of multimedia archives with significant potential for the digital humanities. © 2014 Springer-Verlag.
