Autonomic service configuration for telecommunication MASs with extended role-based GAIA and JADEx
Autonomie Communications have attracted huge attention recently for the management of telecommunication networks in the European Network Research Community. The purpose of this research is to offer the abilities such as autonomy, scalability, adaptation as well as simplicity for management application in complex networks. The accomplished networks inspired by biological mechanisms or market-based concepts could enable agents to be of intelligence, scalablility, and interoperabliliry in the management functional domains with regards to the large volume requirements from services' fulfillment perspective in decentralized Multi-Agent Systems. In accordance with TMF and FIPA specifications and requirements, the autonomy attributes self-configuring, self-adapting, self-limiting, self-preserving, and self-optimizing are involved into our simulation. Resource allocation requests are bidded for a long session in the multi-unit Vickrey-Clarke-Groves auction. This design adopts the software development methodology-GAIA and the framework-JADEx. We have shown multiple service configuration in dynamic network can be nearly optimized by autonomie behaviors via bidding according to business objectives for getting maximum revenues. We conclude this end-to-end approach maintains self-managing capability, easy-to-implement scalability, and more incentively compatible and efficient over other common implementation so that it could achieve the optimal solution to the flexible requirements for the Service Fulfillment for advanced IP networks. © 2005 IEEE
Different understandings of quality education across the globe: a special issue on the guiding theme of the BAICE 2016 Conference Editorial : Editorial, Compare: A Journal of Comparative and International Education
While the concept of ‘quality education’ has been widely debated, there is by no means a universal definition in the literature (e.g. Harvey and Williams 2010; Mishra 2007; Tam 2001). Different approaches and conceptualisations reveal the context-based nature of quality as a value judgement. In the education field in particular, its vagueness is further compounded by the difficulty in measuring education performance: learning outcomes are reflected in transformations of individuals in terms of their knowledge, characteristics and behaviour (Tsinidou, Gerogiannis, and Fitsilis 2010), and these outcomes are defined and understood in ways that are highly contextualised (Tikly 2011; Walker 2006). The critical role of context in the construction of quality education is a central theme in this special issue
Using an Electronic Monitoring System to Link Offspring Provisioning and Foraging Behavior of a Wild Passerine
Although the costs of parental care are at the foundations of optimal-parental-investment theory, our understanding of the nature of the underlying costs is limited by the difficulty of measuring variation in foraging effort. We simultaneously measured parental provisioning and foraging behavior in a free-living population of Zebra Finches (Taeniopygia guttata) using an electronic monitoring system. We fitted 145 adults with a passive transponder tag and remotely recorded their visits to nest boxes and feeders continuously over a 2-month period. After validating the accuracy of this monitoring system, we studied how provisioning and foraging activities varied through time (day and breeding cycle) and influenced the benefits (food received by the offspring) and costs (interclutch interval) of parental care. The provisioning rates of wild Zebra Finches were surprisingly low, with an average of only one visit per hour throughout the day. This was significantly lower than those reported for this model species in captivity and for most other passerines in the wild. Nest visitation rate only partially explained the amount of food received by the young, with parental foraging activity, including the minimum distance covered on foraging trips, being better predictors. Parents that sustained higher foraging activity and covered more distance during the first breeding attempt took longer to renest. These results demonstrate that in some species matching foraging activity with offspring provisioning may provide a better estimate of the true investment that individuals commit to a reproductive attempt
From hegemonic to inclusive masculinities in English professional football: marking a cultural shift
In this article, we conduct a generational study of measuring progress toward the inclusion of homosexuality in professional sport. We accomplish this by interviewing an openly gay football player, Anton Hysén, in the year 2017, using the precise same questions about the relationship between his homosexuality and sport that were asked of the first openly gay premier football player in 1992, Justin Fashanu. We thus measure difference in attitude according to the 25 years that have elapsed between the interviews. Our results emphasis two themes: First, the near-total acceptance of being gay within professional football today, compared to 25 years ago; and second, the social praise that is levied upon today’s openly gay sportsmen, compared to the social stigma placed upon Fashanu
Nest predation research:Recent findings and future perspectives
Nest predation is a key source of selection for birds that has attracted increasing attention from ornithologists. The inclusion of new concepts applicable to nest predation that stem from social information, eavesdropping or physiology has expanded our knowledge considerably. Recent methodological advancements now allow focus on all three players within nest predation interactions: adults, offspring and predators. Indeed, the study of nest predation now forms a vital part of avian research in several fields, including animal behaviour, population ecology, evolution and conservation biology. However, within nest predation research there are important aspects that require further development, such as the comparison between ecological and evolutionary antipredator responses, and the role of anthropogenic change. We hope this review of recent findings and the presentation of new research avenues will encourage researchers to study this important and interesting selective pressure, and ultimately will help us to better understand the biology of birds
Landscape and weather determinants of prey availability: implications for the Lesser Kestrel Falco naumanni
Women After War: Weaving Nostos in Homeric Epic and in the Twenty-First Century
While women play a circumscribed role in ancient epic, Homer\u27s Odyssey depicts both Helen and Penelope as undergoing their own forms of homecoming, or nostos, after the Trojan War: Helen returns to her husband Menelaus after experiencing the war firsthand at Troy and a ten-year separation; Penelope stays home, but Odysseus\u27 return is in many ways as much a challenge for her as it is for him and the Odyssey portrays her domestic ordeal as a form of heroic nostos. In this essay, I explore female ways of homecoming in the Odyssey and draw connections between Homeric heroines and members of Team Lioness returning home from Afghanistan and Iraq in the twenty-first century. The 2008 documentary Lioness gives voice to some of these women, the country\u27s first generation of female combat veterans, as they struggle to reconcile their experience of war in Iraq with their lives at home. While the ancient Greeks could not have conceived of women experiencing battle in the way the members of Team Lioness did, Helen\u27s and Penelope\u27s marginalized roles in the Odyssey open a window into the contemporary experience of women soldiers and veterans and provide ways of understanding the challenges of the trauma of war and female homecoming in the twenty-first century
Exploring the attitudes towards homosexuality of a semi-professional Swedish football team with an openly gay teammate
Men’s contact teamsports, such as football, have historically been understood as a hostile environment for sexual minorities (Hekma, 1998; Parker, 1996; Pronger, 1990). In recent years, however, academic research has documented how teamsports have become increasingly progressive for gay athletes (Anderson, 2011; Anderson & McGuire, 2010; Magrath, Anderson & Roberts, 2015). As has been argued elsewhere in this collection (see Chapter 1 & Magrath & Cleland, Chapter XYZ), high levels of inclusivity have been especially evident in research on football (e.g. Adams, 2011; Adams & Anderson, 2012; Gaston, Magrath & Anderson, 2018; Magrath, 2017a, 2017b, 2018; Magrath, Anderson & Roberts, 2015; Roberts, Anderson & Magrath, 2017).
In this chapter, we aim to investigate the inclusive nature of the teammates of the second active professional footballer to come out, Anton Hysèn. This was a unique opportunity as, historically, the majority of professional athletes wait until their retirement to announce their sexuality (e.g. Cleland, Magrath & Kian, 2018). Hysèn is one of the few professional athletes who has ‘come out’ whilst still playing professional sport, thus allowing the data to present a current reflection of acceptance rather than a historical account of how team members recall their level of acceptance. In this endeavor, we employed surveys to collect data from Hysèn’s teammates, measuring the team’s overall attitudes toward homosexuality; whilst also investigating if there were any socio-negative issues with having an openly gay athlete on the team. This chapter will focus on the male homosexuality and homophobia towards male athletes due the participants in this research being only men
