Visual enhancement of touch in spatial body representation

Perception of our own bodies is based on integration of visual and tactile inputs, notably by neurons in the brain’s parietal lobes. Here we report a behavioural consequence of this integration process. Simply viewing the arm can speed up reactions to an invisible tactile stimulus on the arm. We observed this visual enhancement effect only when a tactile task required spatial computation within a topographic map of the body surface and the judgements made were close to the limits of performance. This effect of viewing the body surface was absent or reversed in tasks that either did not require a spatial computation or in which judgements were well above performance limits. We consider possible mechanisms by which vision may influence tactile processing.

How the European Union does not work: national bargaining success in the Council of Ministers

We know surprisingly little about whether the content of European Union legislation reflects the preferences of some Member States more than others. The few studies that have examined national bargaining success rates for EU legislation have conceptual and methodological weaknesses. To redress these problems I use a salience-weighted measure to gauge the relative success of Member States in translating their national preferences into legislation, and test two plausible, competing hypotheses about how the EU works: that no state consistently achieves more of what it really wants than any other, and that large Member States tend to beat small ones. Neither hypothesis receives empirical support. Not only do states differ far more significantly in their respective levels of bargaining success than previously recognised, but some of the smaller states are the ones that do especially well. The paper‟s main contribution -- demonstrating that the EU does not work as most people think it does -- sets the stage for new research questions, both positive and normative. In the last section I make a tentative start answering two of the most important: which factors explain the surprising empirical results, and whether differential national bargaining success might undermine the legitimacy of the integration process.

N1 enhancement in synesthesia during visual and audio-visual perception in semantic cross-modal conflict situations: an ERP study

Synesthesia entails a special kind of sensory perception, where stimulation in one sensory modality leads to an internally generated perceptual experience of another, not stimulated sensory modality. This phenomenon can be viewed as an abnormal multisensory integration process as here the synesthetic percept is aberrantly fused with the stimulated modality. Indeed, recent synesthesia research has focused on multimodal processing even outside of the specific synesthesia-inducing context and has revealed changed multimodal integration, thus suggesting perceptual alterations at a global level. Here, we focused on audio-visual processing in synesthesia using a semantic classification task in combination with visually or auditory-visually presented animated and in animated objects in an audio-visual congruent and incongruent manner. Fourteen subjects with auditory-visual and/or grapheme-color synesthesia and 14 control subjects participated in the experiment. During presentation of the stimuli, event-related potentials were recorded from 32 electrodes. The analysis of reaction times and error rates revealed no group differences with best performance for audio-visually congruent stimulation indicating the well-known multimodal facilitation effect. We found enhanced amplitude of the N1 component over occipital electrode sites for synesthetes compared to controls. The differences occurred irrespective of the experimental condition and therefore suggest a global influence on early sensory processing in synesthetes.

Developing a knowledge management system using an ontological approach in global organisation

This paper introduces an ontology-based knowledge model for knowledge management. This model can facilitate knowledge discovery that provides users with insight for decision making. The users requiring the insight normally play different roles with different requirements in an organisation. To meet the requirements, insights are created by purposely aggregated transnational data. This involves a semantic data integration process. In this paper, we present a knowledge management system which is capable of representing knowledge requirements in a domain context and enabling the semantic data integration through ontology modeling. The knowledge domain context of United Bible Societies is used to illustrate the features of the knowledge management capabilities.

Acellular Dermal Matrix Graft for Gingival Augmentation: A Preliminary Clinical, Histologic, and Ultrastructural Evaluation

Background: The aim of this study was to evaluate clinically, histologically, and ultrastructurally the integration process of the acellular dermal matrix used to increase the band of keratinized tissue while achieving gingival inflammation control. Methods: Ten patients exhibiting a mucogingival problem with bands of keratinized tissue <= 1 mm and gingival inflammation of the related teeth were included in the study. The surgical procedures were performed to augment the gingival tissue using acellular dermal matrix. Clinical measurements were assessed at baseline and after 3 months. A specimen of the allograft and surrounding tissues was obtained immediately before the surgery and 4 minutes and 1, 2, 3, 4, 6, and 10 weeks after grafting. Results: Clinically, a gain of keratinized tissue of 2.92 +/- 0.65 mm was observed after 3 months. Histologically and ultrastructurally, many macrophages were observed phagocytosing preexisting collagen fibers in the first weeks. From week 2 on, fibroblasts synthesizing new collagen, epithelial cells colonizing the graft surface, and revascularization were noticed. After 6 weeks it was difficult to find the acellular dermal matrix preexisting collagen fibers. This process of substitution was completed after 10 weeks, when the reepithelialization of the entire graft throughout a well-structured basement membrane was achieved. Conclusion: The acellular dermal matrix graft seemed to be an easily handled material for use in keratinized tissue augmentation that, in humans, was substituted and completely reepithelialized in 10 weeks according to histologic and ultrastructural results.

Kritisk diskursanalys av Gy2011 med fokus på kulturkontexten : Politiska diskursers relation till svensk läroplansutveckling

This research aims to relate the modern Swedish curriculum development to the political discourses liberalization and European integration through a critical discourse analysis of the Swedish curriculum Gy2011. These political discourses constitute the cultural context of Gy2011, which according to critical discourse theory is synonymous with the terms social sphere or praxis. The term cultural context includes the environment in which the text has been created as well as its intertextuality – in this case its relations to earlier curricula. The analysis of Gy2011 exhumes scientific research done in the field of curriculum studies, which enables future research. The Gy2011 analysis shows that the political discourses liberalization and European integration stands out within the texts cultural context, and have done so for more than 70 years, a fact that is illustrated by an overview of Swedish curricula history. This research also illuminates how the liberalization discourse accelerated during the 1980’s, by both social democrats and the political right, and that the European integration process has gained momentum in recent years.

Integrated management system:the experiences of three Australian organisations

Purpose – Management systems and standards have become a key part of the organisation's lifeline and a prerequisite for survival in the twenty-first century. Systems for quality environmental and occupational health and safety (OHS) now form the three main pillars of the organisation, the fourth one being financial accounting. In light of the increasing pressure and demands from different stakeholders, it is becoming necessary for organisations to adopt the different systems/standards. However, to achieve the benefits from the implementation and subsequently maintenance of these systems it is only a practical and logical step that the existing management systems/standards be integrated into a single system.

Design/methodology/approach – This paper presents the experiences of three Australian-based organisations that have successfully undertaken the integration of their management systems/standards. Data for this paper were collected through in-depth interviews conducted with the managers responsible for quality, environment and OHS systems.

Findings – The interviews revealed a number of quantifiable and unquantifiable benefits experienced by the companies from operating one integrated system, such as saving of dollars, better utilisation of resources and improved communication across the organisation, to name a few. However, for the benefits to be realized it is essential that organisations are aware of the challenges and obstacles accompanying integration of systems/standards. If these challenges are not addressed early in the process they can delay the completion of the integration process.

Originality/value – Recommendations for other organisations contemplating integrating their management system include: obtaining commitment from the top management; having adequate resources to integrate the systems; having communication and training across the organisation in aspects of integration; and, last but not the least, having integrated audits. Implementation of these recommendations may vary from one organisation to another; however, it would result in lesser resistance for the organisations following them.

The mobile skilled workforce : optimising benefits for rural communities

Many small rural communities with ageing populations and limited opportunities for young people are not attracting skilled workers, but have a flow of skilled people through the community as locums, seasonal workers or contractors. This project investigated the question: how can rural communities capture maximum benefit from professional and other highly skilled workers in the context of an increasingly mobile and transitory workforce? It found that rural communities derive a wide range of benefits from mobile skilled workers. Effectiveness of the integration process determines the nature and extent of mobile skilled worker contribution to the community. Community settings that encourage and support mobile skilled worker integration are identified in terms of culture, leadership and interactional infrastructure. These same settings also influence mobile skilled worker retention in rural communities. Rural communities need to be proactive in matching worker and community characteristics, and this begins with the recruitment process. Mobile skilled workers need assistance and support to develop a primary social contract, and the process needs to be monitored. This is a community-wide responsibility and requires a coordinated, whole-of-community approach. This is the first Australian study to explore how rural communities can capture the advantages from highly skilled mobile workers. Rural communities that make the most of the available pool of skills can increase resilience, identification and uptake of opportunities such as new enterprises, good practice in natural resource management, enhanced social and leisure opportunities, and the quality and range of local services. The importance of this report is that it provides a broad range of strategies for rural communities wanting to know how to optimise the benefits they derive from mobile skilled workers, regardless of their location or rural industry base.

The succession decision in Chinese–Australian family businesses : an exploratory study

This article explores the factors used to make succession choices as ethnic Chinese family business founders integrate into their host country, Australia. An empirical study of six Chinese–Australian family businesses was used to analyse what factors influence the succession decision-making process. Results show three broad factors influenced the founders’ decisions, including the aspirations and visions of the business founders, cultural and individual values shaped in the integration process, and the options that are available for succession. Findings challenge the anticipated option of intergenerational succession, with its emphasis on family-oriented collectivistic values as expectations. It provides future support for considering how the cultural value orientation (collectivistic, individualistic, or transitional) has impacted on the founder’s succession choices. Further research is required to understand how the flexible, changing, situational founder’s succession intentions are manifested among family businesses in cultural transition.

Conceptualizing The Schmittian ‘Exception’ in the European Union: from the ‘Opt-Out’ Procedure(S) to indirect forms of secessionism

Too often, legal and sociopolitical scholars concerned with European policies anddecision-making procedures focus their efforts only on the official essence ofconventional opt-out forms of nonparticipation in the European integration process,such as those established in the Treaty of Lisbon. Yet, far from being just an internalmatter, the independentist instances which informed the Scottish referendum had asignificant impact on delicate issues of EU law, biopolitics, political anthropology,political theology, and foreign policy which deserve to be properly addressed. Thenecessity of conducting such an analysis is self-evident, and mainly related to thepossibility that the Scottish experience may be soon replicated, with different results,in the Italian regions of Venetia, Sardinia, and Lombardy, and in the Spanishcommunity of Catalonia. Delving into this dimension through Schmitt’s politicaldecisionism and adopting a comparative and interdisciplinary approach thattranscends the limits of pure positivistic and analytical lines of inquiry, this paperpresents a country’s choice to leave the EU or stop cooperating with it through thedirect opt-out mechanisms officially regulated in its Treaties, or through indirectforms of secessionism, in terms of an ‘exceptional’ act of sovereign will.

Sistemas de informações sobre recursos hídricos e a dupla dominialidade das águas: o caso da integração do sistema nacional e dos sistemas estaduais de recursos hídricos na Bacia do Rio Paraíba do Sul

The National Water Management Policy was defined by Law 9.433/97 (Water Act), establishing the hydrographic basin as the management unity, independently of geographic limits and respective federal organisms. Nevertheless, water management entities and instruments are directly associated to different federal entities located within the same basin, and depend on them for being effective. The absence of law mechanisms that conciliate the various requisitions of federal organisms located in the same basin is a challenge still without brazilian law support. This study describes the integration process of information systems in Paraíba do Sul river basin. It also emphasizes integration restrictions of these systems, the cooperation level and the instruments used by the various actors and federal organisms in order to meet National Water Management Policy objectives. The management instrument Water Management Information System is presented as an important component that helps the stakeholders decision making process involved in water management, respecting federalism and the water domains defined in the brazilian constitution, and according to the policy established in the Water Act. In theoretical aspects, this work presents the basic concepts of National Water Management Policy institutional arrangement, considering the network aspects in public policy, the limits imposed by federalism and the way that the water domains is defined in the brazilian constitution and according to the brazilian Water Act. Besides, it identifies the most significant questions related with information systems implementation in public administration and water management. It also illustrates how cooperative federalism and information systems may create conditions that do guarantee the National Water Management Policy management instruments operationality within a hydrographic basin. The action research method was used to develop the research and the selected entity was the Fundação Superintendência Estadual de Rios e Lagoas (Serla). Serla was the water management entity in Rio de Janeiro state, at the research beginning. Others methods as bibliographic and documentary research were also used, aiming to describe the hydrographic basin, as well as the processes and systems concerned with the implementation of the National Water Management Policy in Paraíba do Sul basin.

Fatores críticos de sucesso na operação de escritórios de gerenciamento de projeto (PMOs): uma abordagem Delphi

Projetos são precursores de novos produtos, serviços e processos organizacionais. Sendo assim, a gestão de projetos aparece como uma grande oportunidade para organizações nos diversos ramos de atividade. O aumento da complexidade do mundo dos negócios e a crescente competitividade fazem com que as empresas tenham que responder cada vez mais rápida e eficientemente aos estímulos externos. Neste contexto, as falhas na execução dos projetos muitas vezes têm resultados desastrosos. Esta dissertação tem por objetivo identificar e analisar os fatores críticos de sucesso para a operação de Escritórios de Gerenciamento de Projetos (Project Management Office – PMO) nas organizações. O PMO permite às empresas usufruir dos benefícios da integração de processos, assim como informar a alta administração sobre o andamento do seu portfólio de projetos, buscando competitividade no mercado com o sucesso de seus projetos. A pesquisa qualitativa (espontânea) teve participação de especialistas brasileiros e estrangeiros, reconhecidos pelo PMI como pessoas destacadas (consultores especializados) em gerenciamento de projetos. Na pesquisa Delphi, quarenta e três especialistas de vários países foram submetidos a um questionário de vinte e cinco perguntas minuciosamente preparadas, a fim de extrair o máximo possível de informações consideradas críticas nas atividades atuais e tendências de PMOs nas empresas. A pesquisa Delphi foi realizada em duas rodadas e concluída com recomendações efetivas, validadas internacionalmente. Como resultado do trabalho, foi desenvolvido um estudo que poderá ser utilizado como referência para a operação de Escritórios de Gerenciamento de Projetos (PMO) nas empresas sem distinção de segmento.

Start-up acquisition: motivations, difficulties and lesson learned

Em um esforço continuo de sobrevivência, corporações buscam meios para expandir seus negócios, seja dentro de seus mercados atuantes, ou na exploração de novos mercados. Para alcançar esse objetivo, inovações são realizadas pelos funcionários que, por meio de suas iniciativas, praticam o empreendedorismo coorporativo. São diversas formas em que o empreendedorismo corporativo se manifesta, dentre elas por meio de aquisições. Ao comprar uma outra empresa, a empresa compradora tem como motivação a busca de alguns atributos que complementem seus objetivos iniciais. Após a compra, o processo de integração entre as duas empresas é, por muitas vezes, complicado e penoso. O objetivo desse estudo é o de identificar quais são essas motivações de compra, os problemas enfrentados durante a integração entre as duas empresas, e quais são as lições aprendidas por grandes/médias corporações quando adquirem Start-ups. Muitos estudos atualmente tratam de temas relacionados à aquisição de empresas, porém, quando se trata de Start-ups, pouca literatura é encontrada. Os resultados dessa pesquisa são fruto de entrevistas com os gestores e empreendedores que participaram do processo de aquisição da SAMURAI pela Momentum e da Save-me pela Buscapé – empresas brasileiras. Os resultados são seis sugestões que devem ser consideradas por grandes/medias corporações antes e durante o processo de aquisição de uma strat-up: (i) A base de clientes da empresa comprada deve ser cuidadosamente considerada; (ii) um contato muito próximo entre os gestores das duas empresas é crucial antes da realização da aquisição; (iii) a contratação de uma empresa de consultoria em aquisições pode ser primordial durante o processo de integração; (iv) o empreendedor tem um papel de central importância para o future da nova empresa formada após a aquisição; (v) a forma como a integração entre as duas empresas ocorrerá após a compra deve ser cuidadosamente escolhida e (iv) a criação de uma corporate venture deve ser levada em consideração.
