    Organization of Multi-Agent Systems: An Overview

    Full text link
    In complex, open, and heterogeneous environments, agents must be able to reorganize towards the most appropriate organizations to adapt unpredictable environment changes within Multi-Agent Systems (MAS). Types of reorganization can be seen from two different levels. The individual agents level (micro-level) in which an agent changes its behaviors and interactions with other agents to adapt its local environment. And the organizational level (macro-level) in which the whole system changes it structure by adding or removing agents. This chapter is dedicated to overview different aspects of what is called MAS Organization including its motivations, paradigms, models, and techniques adopted for statically or dynamically organizing agents in MAS.Comment: 12 page

    Firms and the Coordination of KnowledgeSome Austrian Insights

    This paper argues that Austrian economics allow us to identify a number of weak spots in the modern economics of organization. Thus, neither the dispersion of tacit and subjectively knowledge in organizations, nor the entrepreneurial discovery process are comprehensively treated in this body of thought. Thinking about these issues in the context of the firm leads to a different, but perhaps complementary perspective on economic organization.Austrian economics, the theory of the firm, dispersed knowledge, coordination

    Patient safety competencies in undergraduate nursing students: a rapid evidence assessment

    Get PDF
    Aims To identify patient safety competencies, and determine the clinical learning environments that facilitate the development of patient safety competencies in nursing students. Background Patient safety in nursing education is of key importance for health professional environments, settings, and care systems. To be effective, safe nursing practice requires a good integration between increasing knowledge and the different clinical practice settings. Nurse educators have the responsibility to develop effective learning processes and ensure patient safety. Design Rapid Evidence Assessment. Data Sources MEDLINE, CINAHL, SCOPUS, and ERIC were searched, yielding 500 citations published between 1 January 2004 - 30 September 2014. Review Methods Following the Rapid Evidence Assessment process, 17 studies were included in this review. Hawker's (2002) quality assessment tool was used to assess the quality of the selected studies. Results Undergraduate nursing students need to develop competencies to ensure patient safety. The quality of the pedagogical atmosphere in the clinical setting has an important impact on the students’ overall level of competence. Active student engagement in clinical processes stimulates their critical reasoning, improves interpersonal communication, and facilitates adequate supervision and feedback. Conclusion Few studies describe the nursing students’ patient safety competencies and exactly what they need to learn. In addition, studies describe only briefly which clinical learning environments facilitate the development of patient safety competencies in nursing students. Further research is needed to identify additional pedagogical strategies and the specific characteristics of the clinical learning environments that encourage the development of nursing students’ patient safety competencies

    Structures of authority : postwar masculinity and the British police

    Get PDF
    The British police procedural novel of the 1950s has attracted little critical attention, perhaps because the decade is seen as a ‘golden age’ of police legitimacy (Loader and Mulcahy, 2003). This perception is reinforced by the cinema of the period, where the police are predominantly represented as embodying traditional masculinities and demonstrating familiar national virtues. They are also shown to be policing a society that was itself fundamentally homogenous. Yet this template bore little resemblance to the realities of crime in the late 1940s and early 1950s, and it needs to be set against developments in the crime novel. While cinema used the genre to reassure, it is less clear whether the police procedural of the period attempted or achieved the same end. This hypothesis is explored through an examination of John Creasey’s popular Gideon books. Characterised by open endings and a disturbing level of violence, these novels demonstrate a significant transition in the representation of the police in British crime fiction, suggesting that the 1950s procedural was not a source of reassurance, but a textual space that recognised and negotiated the pressures of a changing society.PostprintPeer reviewe

    Captured voices in primary school art education.

    Eisner (1972) articulated a long-standing orientation in art education as he described the triadic relationship between socio-centric, child-centred and discipline-centred approaches in art education praxis. Hickman (2005) observed that teachers and students are now positioned to embrace a wider range of discourses as to what art might be. This impacts on why students make art and how it is taught. Wider arts discourse has resulted in influential paradigms and historically preferred arts pedagogies (Efland, 2002, 2004; Eisner, 1972; Kerlavage, 1992; Price, 2005). These discourses influence policy, curriculum, teacher beliefs about art and ultimately the ways in which these influences are played out in classrooms. Eisner (2002) argued the need for "empirically grounded examples of artistic thinking related to the nature of the tasks students engage in, the materials they work with, the context's norms and the cues the teacher provides to advance their students thinking" (p. 217). This paper draws on such theory and a two year action-research project, The Art of the Matter (Fraser et al., 2006) involving case studies and analysis. This paper focuses on a Year 4 to Year 6 'drawing into painting' context taught by experienced generalist teachers in New Zealand primary schools. The influence of school culture and programme structures is explored. I raise questions as to which socio-cultural and discipline-centred voices generalist teachers have been captured by, and consider to what extent it possible to still discern a student whisper under the clamour and control of adult proscribed activity

    Affordances, context and sociality

    Get PDF
    Affordances, i.e. the opportunity of actions offered by the environment, are one of the central research topics for the theoretical perspectives that view cognition as emerging from the interaction between the environment and the body. Being at the bridge between perception and action, affordances help to question a dichotomous view of perception and action. While Gibson’s view of affordances is mainly externalist, many contemporary approaches define affordances (and micro-affordances) as the product of long-term visuomotor associations in the brain. These studies have emphasized the fact that affordances are activated automatically, independently from the context and the previous intention to act: for example, affordances related to objects’ size would emerge even if the task does not require focusing on size. This emphasis on the automaticity of affordances has led to overlook their flexibility and contextual-dependency. In this contribution I will outline and discuss recent perspectives and evidence that reveal the flexibility and context-dependency of affordances, clarifying how they are modulated by the physical, cultural and social context. I will focus specifically on social affordances, i.e. on how perception of affordances might be influenced by the presence of multiple actors having different goals

    College Education and social trust. An Evidence-based Study on the Causal Mechanisms

    Get PDF
    This paper examines the influence of college education on social trust at the individual level. Based on the literature of trust and social trust, we hypothesize that life experience/development since adulthood and perceptions of cultural/social structures are two primary channels in the causal linkage between college education and social trust. In the first part of the empirical study econometric techniques are employed to tackle the omitted-variable problem and substantial evidence is found to confirm the positive effect of college education. In the second part contemporary information is used to examine the hypothetical mechanisms in the causal inference. That life experience is a primary channel via which college education promotes social trust fails to find support in our examination, while individual perceptions of cultural and social structures explain up to 77 percent of the causal effect.

    Austrian Economics and Game Theory a Preliminary Methodological Stocktaking

    Get PDF
    This paper discusses, from the perspective of Austrian economics, the merits and drawbacks of game theory in economics. It begins by arguing that Austrians have neglected game theory at their peril, and then argues that game theoretic reasoning may be one way of modelling key Austrian insights, although some aspects of game theory doesn’t square easily with Austrian economics. However, a major stumbling block for an Austrian acceptance of game theory may lie in the traditional Austrian resistance to formal methods.Austrian economics, game theory
