A partir de la conceptualización de Seguridad Regional de Barry Buzan y Ole Waever y de Robert Stewart y Derrick Frazier, se avanza hacia el resultado de la investigación que permite exponer los factores que conllevaron a el surgimiento de un Complejo de Seguridad Regional entre Argentina, Brasil y Paraguay para diezmar los efectos del Crimen Organizado Transnacional en la Triple Frontera.

Opportunities for magnetospheric research with coordinated cluster and ground-based observations

ESA’s first multi-satellite mission Cluster is unique in its concept of 4 satellites orbiting in controlled formations. This will give an unprecedented opportunity to study structure and dynamics of the magnetosphere. In this paper we discuss ways in which ground-based remote-sensing observations of the ionosphere can be used to support the multipoint in-situ satellite measurements. There are a very large number of potentially useful configurations between the satellites and any one ground-based observatory; however, the number of ideal occurrences for any one configuration is low. Many of the ground-based instruments cannot operate continuously and Cluster will take data only for a part of each orbit, depending on how much high-resolution (‘burst-mode’) data are acquired. In addition, there are a great many instrument modes and the formation, size and shape of the cluster of the four satellites to consider. These circumstances create a clear and pressing need for careful planning to ensure that the scientific return from Cluster is maximised by additional coordinated ground-based observations. For this reason, ESA established a working group to coordinate the observations on the ground with Cluster. We will give a number of examples how the combined spacecraft and ground-based observations can address outstanding questions in magnetospheric physics. An online computer tool has been prepared to allow for the planning of conjunctions and advantageous constellations between the Cluster spacecraft and individual or combined ground-based systems. During the mission a ground-based database containing index and summary data will help to identify interesting datasets and allow to select intervals for coordinated studies. We illustrate the philosophy of our approach, using a few important examples of the many possible configurations between the satellite and the ground-based instruments.

Förståelse, bedömningar och hjälpinsatser : Socialarbetares arbete med män som våldsoffer

This report outlines the background to, and presents the results from the Crime Victim Compensation and Support Authority funded project "Social Workers' understanding of men as victims of crime". The project aimed at describing and analyzing how social workers understand and work with male victims of violence. More precisely, the research has focused on how social workers describe men's vulnerability and how they understand men's needs for assistance, what assistance that is provided and the way the constellations of perpetrators and victims of different gender and contexts in which the violence occurs in affect the understanding of male victims of violence. The study has also been devoted to the question of whether the Support Centers for young crime victims in Sweden provide different types of and different amount of help to young men and women afflicted of violence. The project was conducted in three substudies. The results from substudy 1 show that more young men than women seek support from the Support centers studied. Men predominate in number of cases and in the different categories of crime. The results also show that young men on average receive less assistance over a shorter average duration than young women. This applies irrespective of the category of offense that the vulnerability applies to. Furthermore, the young men, compared to the women, proportionally receive fewer interventions characterized as support and a greater proportion of interventions in the form of information. The results also show that the young men are referred on for further action to a lesser extent than is the case for women. The results from substudy 2 show that social workers tend to focus on whether, and to what extent, young men who are victims of violence themselves have behaved provocatively before the violence incident and if they have put themselves in a social situation that could be interpreted as having contributed to an escalation of the violence they have been subjected to. The results from substudy 2 also show that social workers talk about the men as active in the violent situations they have been involved in and dwell on the extent to which the young men's own actions have contributed to the violence. The results also show that young men who are victims of violence are described as "reluctant" victims who are trying to cope with their situation on their own without the involvement of professional or other helper. The young men are also described as reluctant to talk about their feelings. The results of substudy 3 show that social workers believe that young men, when they become victims of violence, risks losing their sense of autonomy, initiative and decisiveness, that is, attributes that are often linked to the dominating cultural image of masculinity. Furthermore, the results show that social workers estimate that men's practicing of their masculinity, but also the response that men who are traumatized get from society, creates difficulties for them to get help. The results from substudy 3 also shows that attributes and actions that can be connected to the masculinity of young men's, as well as a lack of such attributes and actions are considered to be adequate explanations for the violence the men has suffered. When it comes to violence in public places it is the masculinity that explains the violence and its escalation. When it comes to domestic violence it is the lack of expected male attributes and actions that are used as explanations for the violence that have occurred. The discussion is devoted to the question of how the results should be understood based on the concepts of self-performance, interpretation, negotiation and categorizations, and the consequences the results obtained should have for gender sensitive social work given to abused men.

The world of the Sumerian mother goddess : an interpretation of her myths

The present study is an interpretation of the two myths copied in the Old Babylonian period in which the Sumerian mother goddess is one of the main actors. The first myth is commonly called “Enki and Ninḫursaĝa”, and the second “Enki and Ninmaḫ”. The theoretical point of departure is that myths have society as their referents, i.e. they are “talking about” society, and that this is done in an ideological way. This study aims at investigating on the one hand which contexts in the Mesopotamian society each section of the myths refers to, and on the other hand which ideological aspects that the myths express in terms of power relations. The myths are contextualized in relation to their historical and social setting. If the myth for example deals with working men, male work in the area during the relevant period is discussed. The same method of contextualization is used regarding marriage, geographical points of reference and so on. Also constellations of mythical ideas are contextualized, through comparison with similar constellations in other Mesopotamian myths. Besides the method of contextualization, the power relations in the myths are investigated. According to this latter method, the categories at issue, their ranking, as well as their changed ranking, are noted. The topics of the myths are issues important for the kingship and the country, such as irrigation, trade, health and healing, birth, collective work, artisanry and rivalry. All these aspects are used in order to express what the power relations between the goddess Ninḫursaĝa/Ninmaḫ and the god Enki look like. The relations are negotiated and recalibrated, which leads to the goddess getting a lowered status. Part of the negotiations and recalibrations is gender behavior, which is related to historical developments in society. The present work points to the function of these myths as tools of recalibrating not only deities, but also men and women in society.

Mental health and wellbeing of Australian adolescents: pathways to vulnerability and resilience

The Australian Temperament Project (ATP) provides a unique lens through which to view he pathways to vulnerability and resilience that Australian children take from infancy to adolescence, and beyond. Commencing in 1983, the ATP is now completing its 24th year and 14th wave of data collection. The present paper provides an overview of the data on adolescent antisocial behaviour, substance use, internalising problems and aspects of positive development and wellbeing. Several pathways to vulnerability or resilience are described that vary in their age of onset. Constellations of common risk factors suggest that there may be overlapping priming factors for later mental health problems. A different mix of factors relates to pathways to wellbeing. This unique Australian study provides invaluable insights into stability and change in the pathways to mental health that children take across life.

Interactions and networks in Australian tourism

There are many participants in the tourism network who have vested interests in tourism development. These organizations include hotels, associations of hotels and hotel owners, inbound travel agents, travel wholesalers, tourism industry associations, airlines, cruise lines, tourism promotional agencies, regional and local tourism authorities, SME tourism businesses, conference and convention centres and many more. Individuals in the tourism industry intermittently change employment. They often remain in the industry and can move between types of organizations. Their contacts, associations and personal networks remain useful and indeed are utilized. The Interactive Approach postulated by the IMP Group proposes that both suppliers and manufacturers are often involved in close, long-lasting adaptive relationships. Firms within relationships must work together, share objectives, share information and also communicate clearly and precisely using a common language. Here relationship partners should have a similar point of view on the meaning of marketing strategy and related concepts including market segmentation, differentiation and competitive positioning.

This paper seeks to assess the nature, perspectives and characteristics of interactions in the tourism network in Australia. There are two stages of this research. The first stage obtained the perspectives of network participants on the challenges facing tourism, key growth segments, brand and promotional strategies and customer insights and satisfaction levels. Participants were also asked to provide advice to the national marketing organization on a range of developmental topics. The second stage of this research assesses the interaction patterns among network participants Network picture, network position, resource constellations, interaction, resources and activities, interdependence, adaptation, actor bonds, strategy and change are also assessed. The relationships are political and consultative in nature. There is much interdependence and possible conflict between the network participants. The national tourism body has particular skills in tourism planning and tourism research. They also have significant resources and the ability to influence inbound tourism patterns. This paper seeks to assess and understand the interactions within this network.

Vision and rationalisation : a study of the school psychology profession within the Victorian Government school system

Since its origins in the 19th century, modern schooling has been a continuously contested domain within nation states. Underlying this contestation dynamic lie competing value systems about the social purpose of education; competing values around which are generated different discourses, and which in turn generate inherently contradictory social and organisational structures. As reflected in other areas of society, the 20th century expansion of state-provided schooling has essentially developed around variations of a bureaucratic model Thus, organisational cultures based around bureaucratic values have come to permeate the enterprise of schooling on a world wide scale. Concomitantly, the value for education to be fundamentally associated with human emancipation from psychological, social, political, or economic states of being, persists as a recurring theme in modern schooling. Premised on these understandings, the thesis argues that the development of the practices of school psychology as a profession, like education in general, and special education in particular, has similarly been influenced by tensions between different and competing constellations of values. It is argued that throughout the 20th century, the pervasiveness of formal schooling systems suggest that schooling may be understood as a modernist cultural archetype. As a socially constructed reality, the phenomenon of schooling has become unproblematic the apparent cultural inevitability of formal schooling in the modern era can also be understood as a premise of a systemised way of looking at the world; that of bureaucratic consciousness. Dialectically, bureaucratic consciousness persists in influencing every manifestation of schooling; structurally through its organisational forms, and epistemologically through the institutionalization of teaching and learning. A particular illustration of the dialectical relationship between bureaucratic consciousness and the social forms and social practices of schooling is the school psychology profession which has developed as a part of school systems. The thesis argues that the epistemic archeology of psychology as a knowledge discipline can be traced through an earlier European intellectual and cultural tradition, but in the 20th century, has come to develop a symbiotic yet contradictory relationship with compulsory schooling in the modern nation state. The research study employs historical and fieldwork methods in a study of the development of the school psychology services within the Victorian Education Department, particularly between 1947 and 1987. The thesis also draws upon several usually distinct literatures; the philosophical and theoretical discourse of modernity and post modernity, the history and development of modern schooling, the ethnography of schooling, the international comparative literature on the school psychology profession, and the literature on action research in education practice and curriculum development, As a case study of Victorian school psychology, the research eschews a quantitative statistical approach in favour of qualitative investigatory genres, which have in turn been guided by the values of action research in education, as well as those of critical theory. The important focus of the thesis is its investigation of some aspects of the development and transformations within the Victorian state education bureaucracy, and the dialectical relationship that has persisted between the evolution of change processes and the shifting conceptions of school psychology practices in the 20th century. A history of the organisational development of school psychology services in Victoria constitutes an important part of the thesis. This is complemented by specific illustrations of how some school psychologists have been influenced by and have contributed towards paradigm shifts within the profession, shifts relating to how the changing nature of their work practices have come to be understood and valued by teachers and by school administrators. The work of J. R. MacLeod from the 1950s is noted in this regard. Particular attention is also drawn to the dialectical relationship between bureaucratic consciousness and school psychology's professional orientation in the 1980s. As a means of providing field data to explore this relationship, ethnographic case studies with two school communities are included as part of the fieldwork of the thesis, and are based upon the author's own work in the mid 1980s. These case studies provide a basis for conceptually refraining the school psychologist's professional experience within schooling systems, and an opportunity to examine how competing value systems impact upon the work of the school psychologist. The thesis concludes with some observations about bureaucratic transformations within educational organisations, and about the future relationship of the school psychology profession with schooling systems, as framed by the theoretical parameters of the modernist /post modernist debate. The issue of competing value systems within the administration of public education is re-examined as is the value of promoting human empowerment in the ongoing work of the school psychologist. Finally, some scenario building with reference to the future of school psychology in Victoria in is undertaken.

Global health governance : framework convention on tobacco control (FCTC), the Doha Declaration, and democratisation

Global public health agreements are heralded as a success for the affirmation of the right to health within a complex and contested political landscape. However, the practical implementation of such agreements at the national level is often overlooked. This article outlines two radically different global health agreements: The Doha Declaration on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement and Public Health; and the Framework Convention on Tobacco Control (FCTC). We identify significant challenges in their implementation, particularly for low and middle income countries. Shifts in the policy network constellations around these two agreements have allowed for some positive influence by civil society. Yet industry influence at the national level constrains effective implementation and those affected by these policies have largely been left on the periphery. The broader provisions of these two agreements have been watered down by vested interests and donor conditions. We advocate for both activist and academic actors to play a significant role in highlighting the consequences of these power asymmetries. Deliberative democracy may be the key to addressing these challenges in a way that empowers those presently excluded from effective participation in the policy process.

Geo-social journalism: reorienting the study of small commercial newspapers in a digital environment

This paper begins by problematizing the use of “community” to define and theorize small commercial media outlets that have geography as their primary characteristic—particularly hyper local and small traditional newspapers connected to larger media organizations in digital space. We then extend the concept of “geo-social news” to outline “geo-social journalism” as a specific form of news work currently grouped under the “community media” umbrella. Geo-social is a concept for exploring how small commercial newspapers change as media technologies evolve. It offers a framework for understanding how these news outlets and audiences connect via the notion of “sense of place”. It can also be used as a lens for theorizing their role in social flows and movements and as nodes in the global media network. The practice of “geo-social journalism”, meanwhile, has two dimensions. Firstly, journalists must engage with the land (environment/agriculture/industry), populations, histories and cultures of the places they report news. Secondly, it involves connections and understandings of the shifting constellations of global and national systems, issues and relationships of the digital era. Finally, this paper argues that by its very nature, “geo-social journalism” eschews theoretical universalizing and instead demands fine-grained analyses of the specific dynamic of each “geo-social” publication, its setting and the practices which shape it and it in turn shapes.

The Purpose of the study was to describe and analyze the mobilization of such practices in the socio-historical development of matrices for teaching concepts and skills related to geometric angles, similar triangles, symmetry and proportionality in the training of mathematics teachers. The record of the entire history of investigation into the socio-historical practice, the formative action was based on epistemological assumptions of education ethnomathematics proposed by Vergani (2000, 2007) and Ubiratan D'Ambrosio (1986, 1993, 1996, 2001, 2004) and Alain Bishop conceptions about mathematics enculturation. At the end of the study I present my views on the practices of contributions called socio-cultural and historical for school mathematics, to give meaning to the concept formation and teaching of students, especially the implications of Education Ethnomatematics proposed by Vergani (2000) for training of future teachers of mathematics

Modulação quantizada para sistemas com codificação wavelet sujeitos ao desvanecimento rayleigh

Wavelet coding is an efficient technique to overcome the multipath fading effects, which are characterized by fluctuations in the intensity of the transmitted signals over wireless channels. Since the wavelet symbols are non-equiprobable, modulation schemes play a significant role in the overall performance of wavelet systems. Thus the development of an efficient design method is crucial to obtain modulation schemes suitable for wavelet systems, principally when these systems employ wavelet encoding matrixes of great dimensions. In this work, it is proposed a design methodology to obtain sub-optimum modulation schemes for wavelet systems over Rayleigh fading channels. In this context, novels signal constellations and quantization schemes are obtained via genetic algorithm and mathematical tools. Numerical results obtained from simulations show that the wavelet-coded systems derived here have very good performance characteristics over fading channels

CIGALA: Challenging the solar maximum in Brazil with PolaRxS

The upcoming solar maximum, which is expected to reach its peak around May 2013, occurs at a time when our reliance on high-precision GNSS has reached unprecedented proportions. The perturbations of the ionosphere caused by increased solar activity pose a major threat to these applications. This is particularly true in equatorial regions where high exposure to solar-induced disturbances is coupled with explosive growth of precise GNSS applications. Along with the various types of solar-induced ionospheric disturbances, strong scintillations are amongst the most challenging, causing phase measurement errors up to full losses of lock for several satellites. Brazil, which heavily relies on high-precision GNSS, is one of the most affected regions due notably to the proximity to the southern crest of the ionospheric equatorial anomaly and to the South Atlantic Magnetic Anomaly. In the framework of the CIGALA project, we developed the PolaRxS™, a GNSS receiver dedicated to the monitoring of ionospheric scintillation indices not only in the GPS L1 band but for all operational and upcoming constellations and frequency bands. A network of these receivers was deployed across the whole Brazilian territory in order to first investigate and secondly to mitigate the impact of scintillation on the different signals, ensuring high precision GNSS availability and integrity in the area. This paper reports on the validation of the PolaRxS™ receiver as an ionospheric scintillation monitor and the first results of the analysis of the data collected with the CIGALA network.

Construction of perfect space-time codes

In this work, we propose an innovative methodology to extend the construction of minimum and non-minimum delay perfect codes as a subset of cyclic division algebras over ℚ(ζ3), where the signal constellations are isomorphic to the hexagonal An 2 -rotated lattice, for any channel of any dimension n such that gcd{n, 3) = 1.
