The state and the development of an information society: Greek policy and experience

The paper looks into the dynamics of information society policy and its implementation in the Greek context. It argues that information society development is a contested process, influenced by pre-existing state, economy and society relations. Based on this, it looks into the different aspects of the idiosyncratic path which the evolution of the Greek information society has followed, particularly after 2000. Using Bob Jessop's strategic-relational approach (SRA) to the state as an analytical framework and drawing on a number of in-depth interviews with relevant political actors, it provides insights into policy implementation by examining: the public management of information technology projects, how such projects were received in bureaucratic structures and practices, as well as the relationship between the state and the information and communication technology (ICT) sector in public procurement processes. The emphasis is on the period 2000–2008, during which a major operational programme on the information society in Greece was put into effect. The paper also touches upon the post-2008 experience, suggesting that information society developments might include dynamics operating independently and even in contradiction to the state agenda.

Molecular mechanisms controlling synaptic recruitment of GluA4 subunit-containing AMPAreceptors

Synaptic recruitment of AMPA receptors (AMPARs) represents a key postsynaptic mechanism driving functional development and maturation of glutamatergic synapses. At immature hippocampal synapses, PKA-driven synaptic insertion of GluA4 is the predominant mechanism for synaptic reinforcement. However, the physiological significance and molecular determinants of this developmentally restricted form of plasticity are not known. Here we show that PKA activation leads to insertion of GluA4 to synaptic sites with initially weak or silent AMPAR-mediated transmission. This effect depends on a novel mechanism involving the extreme C-terminal end of GluA4, which interacts with the membrane proximal region of the C-terminal domain to control GluA4 trafficking. In the absence of GluA4, strengthening of AMPAR-mediated transmission during postnatal development was significantly delayed. These data suggest that the GluA4-mediated activation of silent synapses is a critical mechanism facilitating the functional maturation of glutamatergic circuitry during the critical period of experience-dependent fine-tuning.

Is the incipient Chinese civil society playing a role in regenerating historic urban areas? Evidence from Nanjing, Suzhou and Shanghai

Urban regeneration in Western countries can count on a long-lasting tradition of experiences in which civil society has played a fundamental role in counterbalancing the system of power, resulting in profound urban governance readjustments. This has been the result of the increasing centrality of horizontal alliances between citizens and associations involved in urban affairs since the late 1960s in the West. Similar theoretical frameworks have been applied in China. However, these have frequently resulted in conceptual shortcuts that depict civil society as immature or lacking and the state as authoritarian. This paper will explore whether these categories are still entirely valid to urban regeneration in China. While the regime has traditionally prevented horizontal linkages of associations in urban governance (supporting their vertical integration to ensure a certain degree of soft control), there are signs of change. In particular, three cases of urban regeneration in historic areas will be used to discuss the changing role played by civil society in China. The ultimate goal is to examine whether horizontal linkages across groups of heterogeneous citizens are arising at the micro-level of urban governance.

Knowledge Society and Geography: A Theoretical Approach

The transition process between information and knowledge is faster and so the inputs that influence social and political practises. The dissemination of information is now determinant in terms of territorial competitiveness and both public and private sector take large benefits when the data-information- knowledge value chain repeats itself trough space and time. Mankind depends nowadays on the creation and diffusion of good and reliable information. Speed is also important and the greater the speed, the faster the opportunities for global markets. Information must be an input for knowledge and obviously for decision. So, the power of information is unquestionable. This paper focuses on concepts like information, knowledge and other, more geographical and tries to explain how territories change from real to virtual. Knowledge society appears on an evolutional context in which information dissemination is wider and technological potential overwrites traditional notions of Geography. To understand the mutations over the territories, the causes and the consequences emerges the Geography of the Knowledge Society, a new discipline inside Geography with a special concern about modern society and socio-economical developing models.

Quadros Elétricos Inteligentes-Smart Panels

Na sociedade atual, a preocupação com o ambiente, por um lado, e com o conforto e a segurança, por outro, faz com que a sustentabilidade energética se assuma como uma forma de intervenção adequada às exigências de qualidade de vida e à eficiência no âmbito da economia. Nesta conformidade, é incontornável a mais-valia do Smart Panel, um quadro elétrico inteligente criado com vista à consecução daqueles desideratos, o que motivou o tema do presente trabalho. Assim, pretende-se demonstrar as potencialidades do Smart Panel, um novo conceito de quadro elétrico que visa a otimização da sua funcionalidade na gestão dinâmica e pragmática das instalações elétricas, nomeadamente no que respeita ao controlo, monitorização e atuação sobre os dispositivos, quer in loco quer, sobretudo, à distância. Para a consecução deste objetivo, concorrem outros que o potenciam, designadamente a compreensão do funcionamento do quadro elétrico (QE) tradicional, a comparação deste com o Smart Panel e a demonstração das vantagens da utilização desta nova tecnologia. A grande finalidade do trabalho desenvolvido é, por um lado, colocar a formação académica ao serviço de um bom desempenho profissional futuro, por outro ir ao encontro da tendência tecnológica inerente às necessidades que o homem, hoje, tem de controlar. Deste modo, num primeiro momento, é feita uma abordagem geral ao quadro eléctrico tradicional a fim de ser compreendido o seu funcionamento, aplicações e potencialidades. Para tanto, a explanação inclui a apresentação de conceitos teóricos subjacentes à conceção, produção e montagem do QE. São explicitados os diversos componentes que o integram e funções que desempenham, bem como as interações que estabelecem entre si e os normativos a que devem obedecer, para conformidade. Houve a preocupação de incluir imagens coadjuvantes das explicações, descrições e procedimentos técnicos. No terceiro capítulo é abordada a tecnologia Smart Panel, introduzindo o conceito e objetivos que lhe subjazem. Explicita-se o modo de funcionamento deste sistema que agrupa proteção, supervisão, controlo, armazenamento e manutenção preventiva, e demonstra-se de que forma a capacidade de leitura de dados, de comunicação e de comando do quadro elétrico à distância se afigura uma revolução tecnológica facilitadora do cumprimento das necessidades de segurança, conforto e economia da vida moderna. Os capítulos quarto, quinto e sexto versam uma componente prática do trabalho.

Além deste suporte de formação, no quinto capítulo é elaborada uma lista de procedimentos de verificação a serem executados aos componentes de comunicação que integram o Smart Panel, para fornecimento ao quadrista. Por fim, no sexto capítulo incluem-se dois casos de estudo: o estudo A centra-se na aplicação da tecnologia Smart Panel ao projeto de um QE tradicional, que implica fazer o levantamento de toda a aparelhagem existente e, de seguida, proceder à transposição para a tecnologia Smart Panel por forma a cumprir os requisitos estabelecidos pelo cliente. O estudo de caso B consiste na elaboração de um projeto de um quadro eléctrico com a tecnologia Smart Panel em função de determinados requisitos e necessidades do cliente, por forma a garantir as funções desejadas.

American Society of Anesthesiologists Score: Still Useful After 60 Years? Results of the EuSOS Study

OBJECTIVE: The European Surgical Outcomes Study described mortality following in-patient surgery. Several factors were identified that were able to predict poor outcomes in a multivariate analysis. These included age, procedure urgency, severity and type and the American Association of Anaesthesia score. This study describes in greater detail the relationship between the American Association of Anaesthesia score and postoperative mortality. METHODS: Patients in this 7-day cohort study were enrolled in April 2011. Consecutive patients aged 16 years and older undergoing inpatient non-cardiac surgery with a recorded American Association of Anaesthesia score in 498 hospitals across 28 European nations were included and followed up for a maximum of 60 days. The primary endpoint was in-hospital mortality. Decision tree analysis with the CHAID (SPSS) system was used to delineate nodes associated with mortality. RESULTS: The study enrolled 46,539 patients. Due to missing values, 873 patients were excluded, resulting in the analysis of 45,666 patients. Increasing American Association of Anaesthesia scores were associated with increased admission rates to intensive care and higher mortality rates. Despite a progressive relationship with mortality, discrimination was poor, with an area under the ROC curve of 0.658 (95% CI 0.642 - 0.6775). Using regression trees (CHAID), we identified four discrete American Association of Anaesthesia nodes associated with mortality, with American Association of Anaesthesia 1 and American Association of Anaesthesia 2 compressed into the same node. CONCLUSION: The American Association of Anaesthesia score can be used to determine higher risk groups of surgical patients, but clinicians cannot use the score to discriminate between grades 1 and 2. Overall, the discriminatory power of the model was less than acceptable for widespread use.

Haida Totem Poles: Reflections of a Society

The Haida were a First Nations group located on the Northwest Coast of Canada. They were exceptional wood carvers that produced various types of works, the most monumental of which were their totem poles. This dissertation analyses 26 of these open architectural structures, each of which belonged to one of the following five types: frontal, mortuary, memorial, house post, or corner post. Of the representations found on poles, 28 different figures were identified. However, individual poles were found to contain between one and fourteen different figures with frontal poles generally featuring the most. The predominant figures on the inventoried poles proved to be birds, humans, and bears. An iconographic structure of a tripartite character was detected that reflects the religious ideology of the Haida population with birds being featured at the top of the poles, humans in the middle, and bears at the lowest point. It also suggests the possible transition from a hunter-gatherer economy to a food producing economy.***********************************************************************************Os Haida foram um grupo das Primeiras Nações que habitaram a costa Noroeste do Canadá. Eram excepcionais escultores de madeira, tendo produzido variados tipos de artefactos, dos quais os totem poles eram os mais monumentais. Na presente dissertação são analisadas 26 dessas estruturas arquitectónicas de exterior, sendo que cada uma delas pertenceria a um dos seguintes cinco tipos: frontal, funerário, memorial, travemestra, ou postes de esquina. Das representações encontradas nos postes, foram individualizadas 28 figuras. No entanto, em postes isolados foi possível identificar entre uma e catorze figuras distintas, sendo os postes frontais os que apresentavam, geralmente, o maior número. A análise destes postes permitiu detectar uma estrutura iconográfica tripartida que reflectia a ideologia religiosa das populações Haida, representando-se as aves no topo, os humanos a meio, e os ursos na base dos postes. Por outro lado, foi possível sugerir, para estas populações, a transição de uma economia baseada na caça-recolecção para uma economia de produção alimentar.

International Society of Urological Pathology (ISUP) Consensus Conference on Handling and Staging of Radical Prostatectomy Specimens. Working group 2: T2 substaging and prostate cancer volume.

The 2009 International Society of Urological Pathology consensus conference in Boston made recommendations regarding the standardization of pathology reporting of radical prostatectomy specimens. Issues relating to the substaging of pT2 prostate cancers according to the TNM 2002/2010 system, reporting of tumor size/volume and zonal location of prostate cancers were coordinated by working group 2. A survey circulated before the consensus conference demonstrated that 74% of the 157 participants considered pT2 substaging of prostate cancer to be of clinical and/or academic relevance. The survey also revealed a considerable variation in the frequency of reporting of pT2b substage prostate cancer, which was likely a consequence of the variable methodologies used to distinguish pT2a from pT2b tumors. Overview of the literature indicates that current pT2 substaging criteria lack clinical relevance and the majority (65.5%) of conference attendees wished to discontinue pT2 substaging. Therefore, the consensus was that reporting of pT2 substages should, at present, be optional. Several studies have shown that prostate cancer volume is significantly correlated with other clinicopathological features, including Gleason score and extraprostatic extension of tumor; however, most studies fail to demonstrate this to have prognostic significance on multivariate analysis. Consensus was reached with regard to the reporting of some quantitative measure of the volume of tumor in a prostatectomy specimen, without prescribing a specific methodology. Incorporation of the zonal and/or anterior location of the dominant/index tumor in the pathology report was accepted by most participants, but a formal definition of the identifying features of the dominant/index tumor remained undecided.

A gene knockout approach in mice to identify glucose sensors controlling glucose homeostasis.

A key aspect of glucose homeostasis is the constant monitoring of blood glucose concentrations by specific glucose sensing units. These sensors, via stimulation of hormone secretion and activation of the autonomic nervous system (ANS), regulate tissue glucose uptake, utilization or production. The best described glucose detection system is that of the pancreatic beta-cells which controls insulin secretion. Secretion of other hormones, in particular glucagon, and activation of the ANS, are regulated by glucose through sensing mechanisms which are much less well characterized. Here I review some of the studies we have performed over the recent years on a mouse model of impaired glucose sensing generated by inactivation of the gene for the glucose transporter GLUT2. This transporter catalyzes glucose uptake by pancreatic beta-cells, the first step in the signaling cascade leading to glucose-stimulated insulin secretion. Inactivation of its gene leads to a loss of glucose sensing and impaired insulin secretion. Transgenic reexpression of the transporter in GLUT2/beta-cells restores their normal secretory function and rescues the mice from early death. As GLUT2 is also expressed in other tissues, these mice were then studied for the presence of other physiological defects due to absence of this transporter. These studies led to the identification of extra-pancreatic, GLUT2-dependent, glucose sensors controlling glucagon secretion and glucose utilization by peripheral tissues, in part through a control of the autonomic nervous system.
