E-COLLABORATION. THE NEW ECHONOMIC WORLD
No full textIn this paper we will present what e-collaboration means and how can this concept revolutionize the XXI-th century economy. Our analysis leads to a conclusion that the future of business will be based on technological backgrounds. Breaking time and space frontiers will be the key of success in a hard competitive business environment. In our opinion this goals will be achieved by the implementation of groupware. However, our study shows that this field still needs a lot of normalization as concept of e-collaboration still has no standard approaches and many theoreticians still confuse collaboration with the classical “three c” terms.economy
Creating and Leading in an Environment of Collaboration
No full textIn an age of increasingly complex social issues, a global economy, renewed emphasis on positive outcomes, and a scarcity of resources; a culture of collaboration is becoming more prominent. hierarchical leadership is being overshadowed by a new way of leading via collaborative partnerships. This paper will seek to define collaboration and its advantages in today\u27s society. It will identify how society encourages collaboration and various methods used to collaborate. It will explore strategies to build collaborations and what barriers are inherent within that process. Finally, the paper will take a close look at leadership within a collaborative environment. Personal characteristics of effective collaborative leaders will be identified. Effective leadership strategies to encourage collaborative environments will be explored. The paper concludes with the paradoxes inherent to collaborative leadership
Testing models of collaboration among high school science teachers in an electronic environment
No full textTeacher collaboration is one of the strategies for encouraging teaches to work together to achieve their common ends. In a complex modern world, teachers rarely have time to collaborate with each other. E-mail and Internet technology encourages teacher collaboration to emerge with personal interaction. E-mail is rapid, permitting responses within the same day or even a few hours. On the network, teachers can seek advice from teachers on other campuses and around the world, and at the same time, they can build their relationship with other users. In Western Australia, an e-mail network for science curriculum leaders was established in both primary and secondary schools. In 1998, a study showed that 93 heads of science departments in government high schools were connected to this e-mail network, and more than two-thirds of them had their computers connected to the World Wide Web.
This study aims to: firstly, test Fishbough's models of collaboration among high school science teachers in an electronic environment (e-mail and Internet); and secondly, presents a detailed science web site analysis in terms of the potential of these websites to foster collaboration. The investigation is divided into two distinct studies: Study One is a survey of the teachers' perceptions of collaboration via the Internet and Study Two is a detailed science website analysis.
Study One employed both mail questionnaire and face-to-face interview techniques as methods of data collection. The Science Teacher Collaboration via E-mail and Internet Questionnaire was developed and used to collect data on models of collaboration and interaction perspective of collaborative relationships via the Internet of science teachers at the selected schools. The information from quantitative analysis was used to compose the interview schedule. The follow-up interview was conducted with science teachers who agreed to be interviewed at the sample schools.
Study Two adopted a content analysis technique for analysis of data collected from the two kinds of science websites, specific science websites for science teachers and science websites for general audiences from five chosen continents, Australia, Asia, Europe, America and Africa.
The study found that the Consulting model of collaboration is frequently used by science teachers and science web sites from five chosen continents
Early recurrent ischemic stroke complicating intravenous thrombolysis for stroke: incidence and association with atrial fibrillation
No full text<p><b>Background and Purpose:</b> Mechanisms of early neurologic deterioration after treatment with intravenous, recombinant, tissue-type plasminogen activator (IV rt-PA) include symptomatic intracerebral hemorrhage (SICH) and early recurrent ischemic stroke. We observed a number of cases of acute deterioration due to recurrent ischemic events.</p>
<p><b>Methods:</b> We undertook a single-center, retrospective analysis of consecutive acute stroke patients treated with IV rt-PA between January 2006 and December 2008 to define the incidence of early neurologic deterioration (>= 4-point drop on the National Institutes of Health Stroke Scale within 72 hours) and its mechanism. Deterioration was attributed to SICH when associated with a PH1 or PH2 hemorrhage on postdeterioration computed tomography scans, to recurrent ischemic stroke when there was clinical and radiologic evidence of a new territorial infarction or new vessel occlusion, and otherwise to evolution of the incident stroke.</p>
<p><b>Results:</b> Of 228 consecutive IV rt-PA-treated patients, 34 (15%) developed early neurologic deterioration, 18 (8%) secondary to incident strokes 10 (4.4%) due to SICH, and 6 (2.6%) due to early recurrent ischemic events, which were significantly associated with atrial fibrillation (present in 5 of 6 patients; 4 paroxysmal, 1 permanent). In 4 patients, sudden clinical deterioration developed during or shortly after IV rt-PA infusion, and in 2, deterioration developed 3 days later. All died 2 days to 2 weeks later. The single case without atrial fibrillation had a recurrent, contralateral, middle cerebral artery stroke during IV rt-PA infusion and multiple high-signal emboli detected by transcranial Doppler. Early recurrent ischemic stroke accounted for 5 of 12 (42%) cases of early neurologic deterioration in patients with atrial fibrillation.</p>
<p><b>Conclusion:</b> In this single-center series, the incidence of early recurrent ischemic stroke after IV rt-PA was 2.6% and was associated with previous atrial fibrillation.</p>
Narratives of Collaboration in Post-War France, 1944 – 1974
No full textArguing that literary narratives (whether fictional or autobiographical) can provide an important way in which the past is accessed and understood, this thesis uses such narratives to compare and contrast cultural representations of collaboration with the Gaullist political accounts described in Henry Rousso’s Le Syndrome de Vichy. Following the introduction, chapter one examines the perception and characteristics of collaboration, providing a broad analysis of collaboration and collaborators which frames later chapters. There follows a discussion of the generic boundaries between history, autobiography and fiction, showing that novels can contain many of the attributes conventionally ascribed to historical texts, as well as having a freedom of form which allows them to examine and relate subjects not allowed to historical accounts. Next, selected novels (by Marcel Aymé, Jean-Louis Bory, Marie Chaix, Céline, Jean-Louis Curtis, Jean Dutourd, Pascal Jardin, Patrick Modiano, Saint-Loup, and Michel Tournier) are analysed at length to examine how specific forms of collaboration have been understood, and how they subvert Rousso’s schema of repression or marginalisation of the phenomenon. Novels written in the immediate aftermath of the war actually gave a convincing representation of collaboration and the everyday wartime experience, contrasting with the ‘official’ story which sought to forget collaboration. Representations of intellectual and cultural collaboration show that, contrary to de Gaulle’s attempts to portray France as a nation of resisters, high-profile figures from these circles offered a more persuasive alternative to this view. This is also shown to be the case for depictions of military and paramilitary collaboration, which openly describe armed and violent collaboration, challenging and contrasting with the Gaullist representation of mass resistance supported by the civil population. Finally, familial memories are used to revaluate the mode rétro in light of earlier chapters. Although this phenomenon found innovative ways to view the war, it did not represent a wholly new, or more open, account, and was subject to its own repressions and distortions

South African responses to Open Access publishing: a survey of the research community
No full textOpen access publishing offers wide benefits to the scholarly community and may also afford relief to financially embattled academic libraries. The progress of the open access model rests upon the acceptance and validation of open access journals and open archives or institutional repositories by the academic mainstream, particularly by publishing researchers. To what extent are the key actors in the South African research system aware of the advantages of open access? This article reports on the findings of a recent survey undertaken to assess the current awareness, concerns and depth of support for open access amongst local researchers, research managers and policy makers in South Africa. The study focuses on issues of quality, article or author charges and the established academic reward system. It concludes that within the prevailing framework, there is little prospect that academics would choose to publish within open access
journals. Recommendations for advocacy by the library community are proposed
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Investigating the Relationships Between Teacher Identity Norms and Collaboration
No full textThe purpose of this study was to investigate how teacher identity norms relate to teacher collaboration among the practices of elementary teachers in Ontario. Using quantitative research methods, the data indicated two clusters of teacher identity norms. The norm cluster of innovation, interdependence, and cooperation showed positive correlations with collaboration and the norm cluster of conservatism, individualism, and competition showed negative correlations with collaboration. The two clusters of norms also correlated with each other. The data showed that teachers highly valued collaboration as part of their teaching practice but did not always experience it in their school setting. The analysis suggested that if schools reinforce norms of innovation, interdependence, and cooperation, collaboration will be nurtured. Further, the data showed that if norms of conservatism, individualism, and competition are continued in school cultures, then collaboration will not be sustained. As a broad educational reform agenda, teacher collaboration is used (a) to support school cultures, (b) to change teaching practices, and (c) to implement policy-based initiatives. This research is expected to benefit teachers in its capacity to inform policy makers concerning the highly complex nature of teacher collaboration and some of the factors that impact it. With an understanding of the relationships between teacher identity norms and collaboration, it may be possible for policy makers to provide appropriate support structures that reinforce collaboration in teachers' practices as well as predict potential levels of collaboration within school cultures
