Erman; Bingöl Province, Karlıova, Toklular village, 16.vii. 2009, (1 / 3 /0), leg. Esen. Remarks. Due to the presence of well developed hyaline extensions on petiole ventrolaterally, the similarity of A. vavrai and A. kurui was stated by Smit et al. (2000) firstly. In the original description Erman (1993) compared A. kurui with A. processiger Viets, 1930 and A. zapus Cook, 1976, but was not aware of the close similarity with A. vavrai Thon, 1899. Examination of the specimens from Eastern Anatolia (Elazıġ and Bingöl Province–Erman & Özkan 2000; Esen 2011) show that, due to the concave anterior margin of idiosoma, blunt humps on dorsal shield, short cauda and pygal lobes, associated setae of petiole extending to posterior margin of petiole, and similar dimensions of idiosoma, petiole and total length of palp (Thon 1899), A. kurui is in perfect agreement with A. vavrai. Thus A. kurui should be considered a junior synonym of A. vavrai. A description of the Turkish specimens are given below. Male: Idiosoma 864–1135 long (including petiole), 684–864 wide. Anterior margin of idiosoma concave, dorsal shield incomplete, dorsal shield W 384–553, dorsal furrow not extending to lateral margin of idiosoma. Dorsal humps blunt (fig. 6 A). Genital plates wide and extending to lateral margin of idiosoma. Medial distance between fourth coxal plates relatively large (fig. 6 B). Cauda distinct, pygal lobes very short. Hyaline membrane short, with a concave posterior margin. Petiole rounded posteriorly. Petiole L/W 88–110 / 69–76. Petiole with hyaline extensions on ventrolaterally (figs. 6 C, D). Ligulate process small, rounded posteriorly and not extending to posterior margin of petiole (fig. 6 E). Associated setae nearly extending to posterior margin of petiole. Palp total L 283–320. dL of palp segments: P- 1 29–33, P- 2 73–81, P- 3 53–64, P- 4 81–89, P- 5 47–53. P- 2 medially with five setae (fig. 6 F). IV-L- 4 with a spur.

O uso das comunidades virtuais no ensino secundário: o caso do "Palco Virtual" ESEN-Net
No full textMestrado em Gestão da InformaçãoA evolução do fluxo de informação e os potenciais da comunicação
entre pessoas têm-se revelado deveras importante para o sucesso de
diferentes organizações. A escola, enquanto organização social,
apresenta uma complexidade natural própria a que se juntam todas as
valências de ordem educativa, curricular e pedagógica. Tanto no âmbito
educativo como organizacional, as Tecnologias de Informação e
Comunicação (TIC) têm vindo a assumir um papel cada vez mais
influente e imprescindível.
Baseado numa metodologia de trabalho participativo e colaborativo, a
construção de “palcos virtuais” resulta de uma análise de requisitos
funcionais. Deste modo elabora-se um diagnóstico das necessidades
de informação pela replicação das práticas diárias que podem ser quer
suportadas, quer melhoradas por esta nova solução, fazendo-se um
aproveitamento dos recursos físicos e humanos existentes nas escolas.
A partir da iniciativa individual de um professor do grupo de informática
da ESEN (Escola Secundária de Emídio Navarro – Viseu), teve início
em 1999 o projecto ESEN-Net, como uma proposta de metodologia
genérica para a construção de soluções baseadas em intranets para a
gestão pedagógica de escolas do ensino secundário.
O objectivo central deste trabalho é estudar uma comunidade que
desenvolve um projecto de integração das TIC numa escola secundária,
no sentido de proporcionar elementos que possam servir como
contributos para melhorar a sua organização e, eventualmente, como
referência para o desenvolvimento de projectos idênticos noutras
escolas.
A recolha de dados demonstra que a integração da TIC e o palco virtual
ESEN-net veio transformar as práticas diárias na comunidade educativa
através da utilização das redes telemáticas como instrumentos de
ensino-aprendizagem.
As TIC e o palco virtual ESEN-net vieram trazer benefícios à
comunidade escolar, facilitando assim a criação e partilha de informação
e contribuindo para a criação e desenvolvimento de uma comunidade
virtual, onde a construção do saber pode ser feita de uma forma activa e
partilhada.The evolution of information flow and the potentials of communication
between people has indeed shown its importance for the success of
different organizations. The school, while a social organization, presents
a natural and proper complexity which is joined with all the curricular,
pedagogical and educational valences. As much in the educative scope
as organizacional, the Information and Communication Technology (ICT)
have come to assume a more influential and essential a role.

Remarks. Due to the well developed pygal lobes, rounded posterior margin of petiole, concave anterior margin of body and incomplete dorsal shield, the new species is very similar A. ayyildizi Erman, 1993 and A. virens Neuman, 1880. It can be distinguished from A. ayyildizi in the well developed dorsal humps, the posterior margin of the hyaline membrane wider, the associated setae of petiole not extending to posterior margin (in A. ayyildizi associated setae extending to posterior margin of petiole-see fig. 1 F) and posterior margin of ligulate process pointed. Furthermore, differences are found in larger idiosoma size (in A. ayyildizi collected from Bingöl Province maximum L/W 1075 / 680) and preference habitat (A. ayyildizi collected from streams). Arrenurus virens differs from the new species in the wider hyaline membrane posteriorly, the shorter petiole, the associated setae of petiole extending to posterior margin and the genital plates not extending to lateral margin of idiosoma. The female of the new species is, due to the distinct posterolateral corners and shape of the genital field, similar to the female of A. ayyildizi. It differs from A. ayyildizi in the larger idiosoma size (in A. ayyildizi maximum L/W 1027 / 866) and genital valves with wider triangular chitinized patches.Published as part of Esen, Yunus, Erman, Orhan & Dilkaraoglu, Sibel, 2013, Contribution to the study of arrenuroid water mites (Acari: Hydrachnidia) from Turkey, pp. 73-83 in Zootaxa 3666 (1) on page 74, DOI: 10.11646/zootaxa.3666.1.7, http://zenodo.org/record/28385

Results of the Heart Protection Study: Can we still assume a class effect?
No full textStatins share several common features including the mechanism of action, i.e. inhibition of HMG-CoA reductase, as well as LDL-cholesterol (LDL-C) and triglyceride lowering properties. However, statins show minor differences in chemical structure, lipophilicity that could translate into a different pharmacological properties. For example, simvastatin exerted a more favorable effect on HDL-C levels than did atorvastatin when higher doses of the two drugs were compared. Finally, the major considerations to chose between statins for CVD patient therapy include clinical benefits and safety (i.e. evidence-based medicine). Primary prevention trials with pravastatins and lovastatin and secondary prevention trials with pravastatin, fluvastatin and simvastatin have established the clinical benefits of statins. In addition, HPS study was designed to investigate the benefits of simvastatin 40 mg in a broad range of patients at high risk for heart disease including women, the elderly and those with a history of hearth attacks, diabetes, hypertension or vascular disease. The results show the ability of simvastatin to reduce all causes of mortality, vascular death and cardiovascular morbidity. The trial also confirms the safety of simvastatin 40 mg although 60% of patients were receiving additional pharmacological treatment. In summary, it appears that statins are not the same and the choice of the more appropriate statin in high-risk patients should be driven by the evidence-based medicine both in terms of safety and efficacy

A Relational Unsupervised Approach to Author Identification
No full textIn the last decades speaking and writing habits have changed.
Many works faced the author identification task by exploiting frequencybased
approaches, numeric techniques or writing style analysis. Following
the last approach we propose a technique for author identification
based on First-Order Logic. Specifically, we translate the complex data
represented by natural language text to complex (relational) patterns
that represent the writing style of an author. Then, we model an author
as the result of clustering the relational descriptions associated to the
sentences. The underlying idea is that such a model can express the typical
way in which an author composes the sentences in his writings. So,
if we can map such writing habits from the unknown-author model to
the known-author model, we can conclude that the author is the same.
Preliminary results are promising and the approach seems viable in real
contexts since it does not need a training phase and performs well also
with short texts

Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
