Rede social académica

O processo de Bolonha apresenta directivas para a construção de um espaço europeu de ensino superior. A adopção destas directivas requer uma abordagem que favoreça, na prática, a mobilidade dos estudantes que têm dificuldades em compreenderem as oportunidades que lhes são oferecidas. Neste contexto, esta dissertação explora a hipótese de utilização de uma rede social para apoiar a mobilidade de estudantes no espaço europeu. No âmbito desta dissertação propõe-se um modelo de conhecimento para representar os membros de uma rede social vocacionada para apoiar cenários de mobilidade, designada por rede social académica. Este modelo foi obtido pela fusão da ontologia Academic Ontology to Support the Bologna Mobility Process com a ontologia Friend of a Friend Ontology. Para efeitos de avaliação experimental, foi criado um demonstrador numa rede social disponível publicamente na Internet que utiliza uma versão simplificada do modelo proposto. Os cenários usados nas experiências representam situações reais às quais foi aplicado um processo rudimentar de descoberta de conhecimento

A simple genetic basis for complex social behaviour mediates widespread gene expression differences.

A remarkable social polymorphism is controlled by a single Mendelian factor in the fire ant Solenopsis invicta. A genomic element marked by the gene Gp-9 determines whether workers tolerate one or many fertile queens in their colony. Gp-9 was recently shown to be part of a supergene with two nonrecombining variants, SB and Sb. SB/SB and SB/Sb queens differ in how they initiate new colonies, and in many physiological traits, for example odour and maturation rate. To understand how a single genetic element can affect all these traits, we used a microarray to compare gene expression patterns between SB/SB and SB/Sb queens of three different age classes: 1-day-old unmated queens, 11-day-old unmated queens and mated, fully reproductive queens collected from mature field colonies. The number of genes that were differentially expressed between SB/SB and SB/Sb queens of the same age class was smallest in 1-day-old queens, maximal in 11-day-old queens and intermediate in reproductive queens. Gene ontology analysis showed that SB/SB queens upregulate reproductive genes faster than SB/Sb queens. For all age classes, genes inside the supergene were overrepresented among the differentially expressed genes. Consistent with the hypothesized greater number of transposons in the Sb supergene, 13 transposon genes were upregulated in SB/Sb queens. Viral genes were also upregulated in SB/Sb mature queens, consistent with the known greater parasite load in colonies headed by SB/Sb queens compared with colonies headed by SB/SB queens. Eighteen differentially expressed genes between reproductive queens were involved in chemical signalling. Our results suggest that many genes in the supergene are involved in regulating social organization and queen phenotypes in fire ants.

Order and the literary rendering of chaos : children's literature as knowledge, order, and social foundation

Depuis que l'animal humain a conçu un système de technologies pour la pensée abstraite grâce au langage, la guerre contre le monde sauvage est devenu une voie à sens unique vers l'aliénation, la civilisation et la littérature. Le but de ce travail est d'analyser comment les récits civilisationnels donnent une structure à l'expérience par le biais de la ségrégation, de la domestication, de la sélection, et de l'extermination, tandis que les récits sauvages démontrent les possibilités infinies du chaos pour découvrir le monde en toute sa diversité et en lien avec sa communauté de vie. Un des objectifs de cette thèse a été de combler le fossé entre la science et la littérature, et d'examiner l'interdépendance de la fiction et la réalité. Un autre objectif a été de mettre ces récits au cœur d'un dialogue les uns avec les autres, ainsi que de tracer leur expression dans les différentes disciplines et œuvres pour enfants et adultes mais également d’analyser leur manifestations c’est redondant dans la vie réelle. C'est un effort multi-disciplinaires qui se reflète dans la combinaison de méthodes de recherche en anthropologie et en études littéraires. Cette analyse compare et contraste trois livres de fiction pour enfants qui présentent trois différents paradigmes socio-économiques, à savoir, «Winnie-l'Ourson» de Milne qui met en place un monde civilisé monarcho-capitaliste, la trilogie de Nosov sur «les aventures de Neznaika et ses amis» qui présente les défis et les exploits d'une société anarcho-socialiste dans son évolution du primitivisme vers la technologie, et les livres de Moomines de Jansson, qui représentent le chaos, l'anarchie, et l'état sauvage qui contient tout, y compris des épisodes de civilisation. En axant la méthodologie de ma recherche sur la façon dont nous connaissons le monde, j'ai d'abord examiné la construction, la transmission et l'acquisition des connaissances, en particulier à travers la théorie de praxis de Bourdieu et la critique de la civilisation développée dans les études de Zerzan, Ong, et Goody sur les liens entre l'alphabétisation, la dette et l'oppression. Quant à la littérature pour enfants, j'ai choisi trois livres que j’ai connus pendant mon enfance, c'est-à-dire des livres qui sont devenus comme une «langue maternelle» pour moi. En ce sens, ce travail est aussi de «l’anthropologie du champ natif». En outre, j’analyse les prémisses sous-jacentes qui se trouvent non seulement dans les trois livres, mais dans le déroulement des récits de l'état sauvage et de la civilisation dans la vie réelle, des analyses qui paraissent dans cette thèse sous la forme d'extraits d’un journal ethnographique. De même que j’examine la nature de la littérature ainsi que des structures civilisées qui domestiquent le monde au moyen de menaces de mort, je trace aussi la présence de ces récits dans l'expression scientifique (le récit malthusien-darwinien), religieuse, et dans autres expressions culturelles, et réfléchis sur les défis présentés par la théorie anarchiste (Kropotkine) ainsi que par les livres pour enfants écrits du point de vue sauvage, tels que ceux des Moomines.

Capturing Emergent Semantics from Social Annotation Systems

The ongoing growth of the World Wide Web, catalyzed by the increasing possibility of ubiquitous access via a variety of devices, continues to strengthen its role as our prevalent information and commmunication medium. However, although tools like search engines facilitate retrieval, the task of finally making sense of Web content is still often left to human interpretation. The vision of supporting both humans and machines in such knowledge-based activities led to the development of different systems which allow to structure Web resources by metadata annotations. Interestingly, two major approaches which gained a considerable amount of attention are addressing the problem from nearly opposite directions: On the one hand, the idea of the Semantic Web suggests to formalize the knowledge within a particular domain by means of the "top-down" approach of defining ontologies. On the other hand, Social Annotation Systems as part of the so-called Web 2.0 movement implement a "bottom-up" style of categorization using arbitrary keywords. Experience as well as research in the characteristics of both systems has shown that their strengths and weaknesses seem to be inverse: While Social Annotation suffers from problems like, e. g., ambiguity or lack or precision, ontologies were especially designed to eliminate those. On the contrary, the latter suffer from a knowledge acquisition bottleneck, which is successfully overcome by the large user populations of Social Annotation Systems. Instead of being regarded as competing paradigms, the obvious potential synergies from a combination of both motivated approaches to "bridge the gap" between them. These were fostered by the evidence of emergent semantics, i. e., the self-organized evolution of implicit conceptual structures, within Social Annotation data. While several techniques to exploit the emergent patterns were proposed, a systematic analysis - especially regarding paradigms from the field of ontology learning - is still largely missing. This also includes a deeper understanding of the circumstances which affect the evolution processes. This work aims to address this gap by providing an in-depth study of methods and influencing factors to capture emergent semantics from Social Annotation Systems. We focus hereby on the acquisition of lexical semantics from the underlying networks of keywords, users and resources. Structured along different ontology learning tasks, we use a methodology of semantic grounding to characterize and evaluate the semantic relations captured by different methods. In all cases, our studies are based on datasets from several Social Annotation Systems. Specifically, we first analyze semantic relatedness among keywords, and identify measures which detect different notions of relatedness. These constitute the input of concept learning algorithms, which focus then on the discovery of synonymous and ambiguous keywords. Hereby, we assess the usefulness of various clustering techniques. As a prerequisite to induce hierarchical relationships, our next step is to study measures which quantify the level of generality of a particular keyword. We find that comparatively simple measures can approximate the generality information encoded in reference taxonomies. These insights are used to inform the final task, namely the creation of concept hierarchies. For this purpose, generality-based algorithms exhibit advantages compared to clustering approaches. In order to complement the identification of suitable methods to capture semantic structures, we analyze as a next step several factors which influence their emergence. Empirical evidence is provided that the amount of available data plays a crucial role for determining keyword meanings. From a different perspective, we examine pragmatic aspects by considering different annotation patterns among users. Based on a broad distinction between "categorizers" and "describers", we find that the latter produce more accurate results. This suggests a causal link between pragmatic and semantic aspects of keyword annotation. As a special kind of usage pattern, we then have a look at system abuse and spam. While observing a mixed picture, we suggest that an individual decision should be taken instead of disregarding spammers as a matter of principle. Finally, we discuss a set of applications which operationalize the results of our studies for enhancing both Social Annotation and semantic systems. These comprise on the one hand tools which foster the emergence of semantics, and on the one hand applications which exploit the socially induced relations to improve, e. g., searching, browsing, or user profiling facilities. In summary, the contributions of this work highlight viable methods and crucial aspects for designing enhanced knowledge-based services of a Social Semantic Web.

Ontology modeling for generation of clinical pathways

Purpose: Increasing costs of health care, fuelled by demand for high quality, cost-effective healthcare has drove hospitals to streamline their patient care delivery systems. One such systematic approach is the adaptation of Clinical Pathways (CP) as a tool to increase the quality of healthcare delivery. However, most organizations still rely on are paper-based pathway guidelines or specifications, which have limitations in process management and as a result can influence patient safety outcomes. In this paper, we present a method for generating clinical pathways based on organizational semiotics by capturing knowledge from syntactic, semantic and pragmatic to social level. Design/methodology/approach: The proposed modeling approach to generation of CPs adopts organizational semiotics and enables the generation of semantically rich representation of CP knowledge. Semantic Analysis Method (SAM) is applied to explicitly represent the semantics of the concepts, their relationships and patterns of behavior in terms of an ontology chart. Norm Analysis Method (NAM) is adopted to identify and formally specify patterns of behavior and rules that govern the actions identified on the ontology chart. Information collected during semantic and norm analysis is integrated to guide the generation of CPs using best practice represented in BPMN thus enabling the automation of CP. Findings: This research confirms the necessity of taking into consideration social aspects in designing information systems and automating CP. The complexity of healthcare processes can be best tackled by analyzing stakeholders, which we treat as social agents, their goals and patterns of action within the agent network. Originality/value: The current modeling methods describe CPs from a structural aspect comprising activities, properties and interrelationships. However, these methods lack a mechanism to describe possible patterns of human behavior and the conditions under which the behavior will occur. To overcome this weakness, a semiotic approach to generation of clinical pathway is introduced. The CP generated from SAM together with norms will enrich the knowledge representation of the domain through ontology modeling, which allows the recognition of human responsibilities and obligations and more importantly, the ultimate power of decision making in exceptional circumstances.

Rethinking the ontology of the shareholder model of the corporation

Purpose – The purpose of this paper is to examine the critical assumptions lying behind the Anglo American model of corporate governance. Design/methodology/approach – Literature review examining the concept of a nexus of contracts underpinning agency theory which, it is argued, act as the platform for neo-liberal corporate governance focusing on shareholder wealth creation. Findings – The paper highlights the unaddressed critical challenge of why eighteenth century ownership structures are readily adopted in the twenty-first century. Social implications – A re-examination of wealth creation and wealth redistribution. Originality/value – The paper is highly original due to the fact that few contributions have been made in the area of rethinking shareholder value.

Social justice in education in 'new times'

This thesis considers social justice in education in ‘new times’. To facilitate the investigation a number of research questions were pursued. These questions were: • What is meant by the label ‘social justice’? • How is social justice to be understood in contemporary terms? • Are there tensions between traditional and contemporary views of social justice? • How effective are policy developments in delivering social justice via education? • What difference do such policies make at the local level? To answer these questions a critical case analysis of a country community and one of its primary schools was carried out. Data were gathered using a variety of methods. As a researcher who was also a teacher in the school I kept a personal professional journal during 1993 and 1994. During this period I was the teacher in the school with responsibility for curriculum development related to issues of social justice. In 1994 I conducted interviews with twenty students, parents and teachers at the school in relation to social justice issues. I also interviewed the CEO of the town’s Council. A number of relevant Federal and State Government and school policy documents were consulted and an archival search of the local newspaper from 1956 to 1994 was undertaken. Statistical information from the Australian Bureau of Statistics as well as from school records was used. A number of local history books were consulted as well as the minutes of relevant school committee meetings. Contemporary social theory, more specifically the work of Anthony Giddens, provided the major methodological tool. Giddens structuration theory was selected as it provided a way of interpreting society from both macro and micro perspectives, it provided a way of studying the interconnectedness of the individual and society. In addition to this, a metaphor was used as a way of developing an understanding of the data. The river was chosen as the metaphor as it has significance to the case study community and it also provides a way of understanding interconnectedness. At an interpretive level, both social theory and moral philosophy were drawn on, including the work of Geoffrey Sharp, Anthony Giddens and Alisdair MacIntyre. A review of selected literature indicated three main areas of concern in relation to this thesis. We live in a time of constant and ongoing change, understanding how this change impacts on the lives of individuals and society is important. Such an understanding relates directly to issues of ontology. In addition it was necessary to consider schools in these ‘new times’. The literature revealed that the changes occurring in the wider society were related to the changes currently being seen in schools. Specifically this related to the increasing emphasis on economics and on individualism, emphases also reflected in the findings of this thesis. Finally the literature related to social justice was discussed, the focus here was on distributive theories of justice and the way these are reflected in programs such as the DSP. The data, as expressed in the metaphor of the flowing river, revealed dominant and marginal currents in social justice in education in ‘new times’. The dominant social group are the intellectually trained and the dominant issues were related to technology, globalisation and economic and bureaucratic rationalism. In the marginal currents we find the under-employed and the unemployed and marginal issues relating to housing, the black economy, poverty and the survival of rural communities. The data also revealed a marginal tributary running into the river. This tributary shows that social cohesion is still a part of life in ‘new times’, albeit a marginalised part. The dominant and marginal currents in social justice in ‘new times’ reveal changes at a deep cultural level. Social justice in ‘new times’ is set within the limits provided by economic rationalism. Such a position is closely linked to the rise of liberal democracy as a political ideology. A rise which has been on a global scale. This valorizes the individual as compared with the group, and the family as compared to the social whole, within the context of expanded economic groupings and markets. Such an ideological position sees the role of the state as providing the ‘legitimising muscle’ to advance the cause of individuals and their families as compared to larger social groupings. These perceptions were applied in Australia, even under a Labor Government. In this sense social justice policies in ‘new times’ are ideological, they act as a political lever to legitimate economic restructuring. They are policies designed to carry disparate groups forward and together on a common wave of economic reform. They are used to ‘sell’ economic reform as being ‘good’ for all of society. Against the backdrop of economic rationalism and liberal democratic ideals there emerges a language geared to the production of an economically viable self, self image, self identity, self esteem and self confidence. As a result, the sense of identity as ‘social’ is lost from view. This thesis argues that what is needed is a new way of looking at social justice in education. A way that reaches beyond the solutions forwarded by the political Left and the Right. It is about the development of an understanding of the way in which an assimilation of the hyper individual and the social group can result in the emergence of the socially responsible individual. This is a cultural shift that sees the individual/society dualism presented in a new way. The categories enter into a new relationship where the balance shifts away from the individual towards society. A shift to a culture where the individual’s rights and responsibilities are respected within a social whole. Such a cultural shift would result in a curriculum which would build social identity, promoted socially responsible independent thought and make space for creativity and the aesthetic. A ‘curriculum for social responsibility’ would be a socially just curriculum.

As fire burns : functional work and praxis in ontology

The context: the historical and philosophical demise of the Marxist model of praxis as a unity of theory and practice organized by a Party in service of a Cause. The task: to remodel praxis by distinguishing it from functional work. The proving ground: the discourse of ontology. The thesis works through four types of ontology in its attempt to construct different ontological schemas for praxis and functional work. In the first three ontologies, Platonic, Aristotelian and relativist, ontological impasses occur in the accounts of the relation between one and the multiple, and of the existence of order. They prevent the successful construction of a schema for functional work. It is in the set-theory ontology of Alain Badiou that the means arise for the passage through these impasses and the definitive construction of distinct ontological schemas for functional work and praxis. This results in a new concept of praxis and a multiplication of its domains beyond politics to science, art and love

Reflective positioning : the impact of conversations in the social and cultural environment of midwifery practice settings on professional learning for students

Literature reviews on the topic of reflection and reflective practice encompassed midwifery, nursing, medicine, allied health, education and professional education. This investigation also included socio-psychological theories by leading authors such as Benner (nursing), Schön (professional education) and positioning theory by Harré and others. Positioning is a psycho-sociological ontology in which individuals metaphorically position themselves within three entities: people, institutions, and societies, where conversations are constructed and make an impact upon the social world. The social and cultural structures and interactions developed in Archer’s morphogenesis were examined in terms of the impact of possible encounters and the transformational effects of learning experiences in practice settings. These bodies of work provided the theoretical framework for the author’s research of students’ experiences in midwifery education for postgraduate students from which selected excerpts with three participating students and their supervising midwives are presented. These excerpts are related to reflective practices and the professional conversations conducted between students and midwives. It was found that reflective positioning applied in midwifery education by students can serve as an analytical tool in explaining social and cultural elements of clinical placements to influence and transform their learning. The potency of conversations that occur in everyday moment-to-moment interactions do contribute to students’ induction in professional midwifery practice and their identity formation as a midwife.

The relevance of perspectivism to the task of modularisation in ontology development

An ontology development methodology seeks to provide developers with established principles, processes, practices, methods and activities for developing ontologies (Gasevic et al., 2009). Diverse methodologies have been published for the development of ontologies, and have evolved, based on the diverse experiences of researchers and practitioners, and the development teams who surveyed the benefits and shortcomings of the available methodologies in order to determine the applicability of methodologies to particular contexts. An evaluation of existing ontology development methodologies has identified that the concept formulation process is not well defined, or based on rigorous processes (Castro et al., 2006; Winters & Tolk, 2009). In order for the validity of the social realism of the actors in a social setting to be captured, the perspectives of each actor needs to be acknowledged and incorporated into the concept formulation process / framework. This paper demonstrates how consideration of perspectivism leads to a meaningful modularisation of the resultant ontology.

Legal systemology and the geopolitics of Roman law: a response to Stuart Elden’s critique of Carl Schmitt’s spatial ontology

This paper explores the production, destruction, and reproduction of the geopolitical spaces of Roman law in order to offer an analysis of Schmitt’s (selective) notion of Jus Publicum Europaeum and its relevance to the current “depoliticization” and “dejuridification” of the world. By adopting a historical and geopolitical approach that reaches the boundaries of legal systemology and political theology, the present contribution investigates the manipulative and instrumentalist use of the material object of Rome’s (universalist) competence, namely the “territory” as dominium of its political intervention, which was ultimately (and idealistically) aimed at avoiding the natural destiny of any living being: birth, maturity, and death. Attention is therefore paid to the Roman strategy of (ontological?) contamination of its mythical identity through the legal and sociopolitical administration and regulation of its geographical spaces in terms of (non-)cultural signification. Through the analysis of such concepts as “nomos,” “Großraum,” “Ortung,” and “Ordnung,” it is claimed that Schmitt voluntarily chose to identify the Jus Publicum Europaeum with the geopolitical order produced during the Age of Discovery and not with the “comprehensive” Roman spatial order. The reason for this choice may be identified in the distortive use of Rome’s social relations and political allegiances that lay at the core of its genealogical expansionism (and subsequent inevitable dissolution) since the conquest of Veius in 396 BC and the historical compromise between patrician nobility and plebeians in 367 BC.

Genes involved in thoracic exoskeleton formation during the pupal-to-adult molt in a social insect model, Apis mellifera

Background: The insect exoskeleton provides shape, waterproofing, and locomotion via attached somatic muscles. The exoskeleton is renewed during molting, a process regulated by ecdysteroid hormones. The holometabolous pupa transforms into an adult during the imaginal molt, when the epidermis synthe3sizes the definitive exoskeleton that then differentiates progressively. An important issue in insect development concerns how the exoskeletal regions are constructed to provide their morphological, physiological and mechanical functions. We used whole-genome oligonucleotide microarrays to screen for genes involved in exoskeletal formation in the honeybee thoracic dorsum. Our analysis included three sampling times during the pupal-to-adult molt, i.e., before, during and after the ecdysteroid-induced apolysis that triggers synthesis of the adult exoskeleton. Results: Gene ontology annotation based on orthologous relationships with Drosophila melanogaster genes placed the honeybee differentially expressed genes (DEGs) into distinct categories of Biological Process and Molecular Function, depending on developmental time, revealing the functional elements required for adult exoskeleton formation. Of the 1,253 unique DEGs, 547 were upregulated in the thoracic dorsum after apolysis, suggesting induction by the ecdysteroid pulse. The upregulated gene set included 20 of the 47 cuticular protein (CP) genes that were previously identified in the honeybee genome, and three novel putative CP genes that do not belong to a known CP family. In situ hybridization showed that two of the novel genes were abundantly expressed in the epidermis during adult exoskeleton formation, strongly implicating them as genuine CP genes. Conserved sequence motifs identified the CP genes as members of the CPR, Tweedle, Apidermin, CPF, CPLCP1 and Analogous-to-Peritrophins families. Furthermore, 28 of the 36 muscle-related DEGs were upregulated during the de novo formation of striated fibers attached to the exoskeleton. A search for cis-regulatory motifs in the 5′-untranslated region of the DEGs revealed potential binding sites for known transcription factors. Construction of a regulatory network showed that various upregulated CP- and muscle-related genes (15 and 21 genes, respectively) share common elements, suggesting co-regulation during thoracic exoskeleton formation. Conclusions: These findings help reveal molecular aspects of rigid thoracic exoskeleton formation during the ecdysteroid-coordinated pupal-to-adult molt in the honeybee.
