Adopting web-based learning and teaching: a case study in higher education

Most universities worldwide are becoming distance education providers through adopting web-based learning and teaching via the introduction of learning management systems that enable them to open their courses to both on- and off-campus students. Whether this is an effective introduction depends on factors that enable and impede the adoption of such systems and their related pedagogical strategies. This study examines such factors related to adopting a learning management system in a large multicampus urban Australian university. The research method used case study approaches and purposively selected the sample consisting of innovative teaching academics from across the university, who used web-based approaches to teach both on- and off-campus learners. The data were analyzed using a combination of Rogers' theory of diffusion of innovations and actor-network theory and revealed a series of enabling and impeding factors faced by pioneering technology-adopter teaching academics, some of which are technology related while others are policy related and common to large multicampus institutions. The study found that safe adoption environments recognizing career priorities of academics are a result of the continuous negotiation between the evolving institution and its innovative and creative staff. The article concludes with a series of conditions that would form a safe, enabling, and encouraging environment for technology-adopter teaching academics in a large multicampus higher education setting.

Sedation and analgesia management for mechanically ventilated adults: literature review, case study and recommentations for practice.

The quality of sedation management in mechanically ventilated patients has been a source of concern in recent years. This paper summarises the literature on the principles of optimal sedation, discusses the consequences of over and undersedation, highlighting the importance of appropriate pain management, and presents a case study using the results of an audit of 48 mechanically ventilated adults. As a result of the review and audit, we are implementing changes to practice.

The most important recommendations from the literature are the use of a sedation scale, setting of a goal sedation score, appropriate pain management and implementation of a nurse initiated sedation algorithm. Other recommendations include use of bolus rather than continuous sedative infusions and recommencing regular medications for anxiety, depression and other phychiatric disorders as soon as possible. A recommendation arising from our audit was the need to identify patients at high risk of oversedation and undersedation and adopt a proactive rather than reactive approach to management. The practice goal is to provide adequate and appropriate analgesia and anxiolysis for patients. This will improve patient comfort while reducing length of mechanical ventilation and minimising risk of complications.

Teaching about the Holocaust : essays by college and university teachers

This collection of fourteen essays by renowned scholars in the field of Holocaust studies seeks to reflect on the experience of teaching and researching this complicated and emotional topic. Contained within are the pioneering stories of those presently engaged in the work of Holocaust education. Separately, they represent a variety of disciplines and orientations. Collectively, they give evidence of the strong commitment to continue this important work, and the moral and ethical demands such teaching, writing, and research place upon all who engage in it. Different perspectives from historical, philosophical, and religious frameworks come together to create a unique contribution to the literature on the Holocaust. Educators discuss what they teach, their methodologies and theoretical orientations and reflect on their own journeys that brought them to this field. The unique nature of these stories bring needed background to the field of Holocaust studies and also serve to inspire others to enlarge their thinking and understanding of previous work on this topic. The stories of these committed Holocaust educators will serve to inspire a new generation of thinkers, writers, and activists to engage in such work. In reading their stories, their collective commitment to make a difference today and tomorrow shines through. This volume will be a valuable resource for courses in the Holocaust, contemporary post-Holocaust realities, as well as courses in genocide. Scholars and anyone with an interest in enriching their understanding of the Holocaust will find much within to inspire them and provoke new ideas.

Social networking and teaching : an Australian case study

In recent years, the Internet has impacted all aspects of modern society. We have now seen the phenomenon of social networking and the impact that this had upon all aspects of modern society including higher education. An issue is how can these social networking technologies relate to tertiary education and how can they be used in this educational context. This paper is based on two case studies which were conducted at an Australian University into the usage of two social networking systems in a teaching environment. The results of these case studies were assessed using a socio-technical framework.

A cross-national study of teaching and learning in primary science classrooms

This presentation reports on the methodological issues confronting an Australian-German-Taiwanese team planning comparative video ethnographic research into primary science classrooms. The issues that will be canvassed include: the benefits of cross-cultural comparisons in providing perspectives on local practice, the theoretical justifications of such comparisons, selection of cases for comparison and possibilities for claiming cultural representativeness, the planning of appropriate data sets, the different comparative stories offered by different analytical frames, practical issues of communication and data sharing, and issues of entanglement of language and culture in the analysis.

Borrelia in granuloma annulare, morphea and lichen sclerosus: a PCR-based study and review of the literature

Morphea, granuloma annulare (GA) and lichen sclerosus et atrophicans (LSA) have also been suggested to be linked to Borrelia infection. Previous studies based on serologic data or detection of Borrelia by immunohistochemistry and polymerase chain reaction (PCR) reported contradictory results. Thus, we examined skin biopsies of morphea, GA and LSA by PCR to assess the prevalence of Borrelia DNA in an endemic area and to compare our results with data in the literature.

Is clipping the preferable technique to perform sympathicotomy? A retrospective study and review of the literature

PURPOSE Thoracoscopic sympathetic surgery is nowadays a broadly accepted technique in the treatment of primary hyperhidrosis as well as facial blushing. The objective of this study was to compare the two currently most commonly used methods for thoracic sympathicotomy: transection (ETS) and clipping (ETC.). METHODS This is a retrospective study on a total of 63 patients, who underwent rib-oriented sympathicotomy, either by transection (n = 36, 57 %) or by clipping (n = 27, 43 %). Moreover, the up-to-date international literature is reviewed concerning which level(s) of the sympathetic trunk should be addressed, depending on the patients underlying condition. Furthermore, the highly controversial topic of reversibility of sympathetic clipping is debated. RESULTS Our results confirm that clipping is at least as effective as transection of the sympathetic chain in the treatment of hyperhidrosis and facial blushing. Furthermore, the analysis of all larger studies on unclipping in humans shows a surprisingly high reported reversal rate between 48 and 77 %. CONCLUSIONS Depending on the symptoms of the patient, different levels of the sympathetic chain should be addressed. When a higher rib level such as R2 is approached, which more likely will result in moderate to severe compensatory sweating, clipping should be preferred as it seems that this technique has indeed a potential for reversibility. As demonstrated, this method is at least as effective as an irreversible transection of the sympathetic chain.

A case study of teachers' mathematics content knowledge and attitudes toward mathematics and teaching

This study intended to measure teacher mathematical content knowledge both before and after the first year of teaching and taking graduate teacher education courses in the Teach for America (TFA) program, as well as measure attitudes toward mathematics and teaching both before and after TFA teachers’ first year. There was a significant increase in both mathematical content knowledge and attitudes toward mathematics over the TFA teachers’ first year teaching. Additionally, several significant correlations were found between attitudes toward mathematics and content knowledge. Finally, after a year of teaching, TFA teachers had significantly better attitudes toward mathematics and teaching than neutral.
