Behaviour and buoyancy regulation in the deepest-diving reptile : the leatherback turtle

In the face of the physical and physiological challenges of performing breath-hold deep dives, marine vertebrates have evolved different strategies. Although behavioural strategies in marine mammals and seabirds have been investigated in detail, little is known about the deepest-diving reptile – the leatherback turtle (Dermochelys coriacea). Here, we deployed tri-axial accelerometers on female leatherbacks nesting on St Croix, US Virgin Islands, to explore their diving strategy. Our results show a consistent behavioural pattern within dives among individuals, with an initial period of active swimming at relatively steep descent angles (∼–40 deg), with a stroke frequency of 0.32 Hz, followed by a gliding phase. The depth at which the gliding phase began increased with the maximum depth of the dives. In addition, descent body angles and vertical velocities were higher during deeper dives. Leatherbacks might thus regulate their inspired air-volume according to the intended dive depth, similar to hard-shelled turtles and penguins. During the ascent, turtles actively swam with a stroke frequency of 0.30 Hz but with a low vertical velocity (∼0.40 ms–1) and a low pitch angle (∼+26 deg). Turtles might avoid succumbing to decompression sickness (‘the bends’) by ascending slowly to the surface. In addition, we suggest that the low body temperature of this marine ectotherm compared with that of endotherms might help reduce the risk of bubble formation by increasing the solubility of nitrogen in the blood. This physiological advantage, coupled with several behavioural and physical adaptations, might explain the particular ecological niche the leatherback turtle occupies among marine reptiles.

Capacity-building in nonprofit organizations : Is there a blended learning paradigm for the sector?

Blended learning models are widely-used, successful training vehicles for e-learning and workplace training, in corporate as well as higher education environments. Increasingly, Web 2.0 applications, imbedded within blended learning models, are being recognized for their utility in these settings. Concern for the sustainability and relevance of nonprofit organizations has sharpened the interest in building effective capacity-building models for the sector. Can Web 2.0 technologies enhance capacity-building models in the Third Sector? Because blended learning is a remarkably adaptable and fluid model, its potential for transforming capacity-building models in the nonprofit sector is thought to be significant. This paper introduces the concept of transformational approaches to capacity-building and asks if blended learning paradigms that incorporate interactive next-generation technologies might strike a responsive chord in the sector. The authors present research to date on blended learning and capacity-building to lay the foundation for the introduction of one blended learning model for training and education in the nonprofit sector. While the authors suggest that blended learning, as it is evolving, is the key to driving innovation in capacity-building models, they recognize that tailoring blended learning to the audience is critical in achieving success. It is suggested that for optimal results, capacity-building efforts should be built on holistic approaches to the integration of individual self-actualization goals with mechanisms for organizational and sector empowerment, using the technologies imbedded with blended learning. © 2011 Springer-Verlag.

Capacity-building in nonprofit organizations using blended learning as a gateway to practitioner education

Experience to date in for-profit as well as in educational settings has demonstrated that blended learning models are effective training vehicles for online instruction and workplace training. Increasingly, technology is playing a critical role in how e-learning is being delivered. Concern for the sustainability and relevance of nonprofit organizations has heightened interest in building effective capacity-building models for the sector. Because blended learning is a remarkably adaptable and fluid model, its potential for transforming capacity-building models in the nonprofit sector can be significant. Are web-based technologies enhancing capacity-building models in the Third Sector? This chapter explores the use of blended learning models within different educational environments to provide the context for asking the question: can blended learning paradigms that incorporate interactive next-generation technologies be widely accepted and implemented in the Third Sector? To establish a baseline for future studies, researchers surveyed nonprofit practitioners in Western Pennsylvania, US and Victoria, Australia. Results from three surveys conducted in 2011 reflect an awareness of the value of web-based training and education for nonprofit practitioners, but do not provide evidence of widespread usage. © 2013 Nova Science Publishers, Inc.

Motivation, self-assessment and tacit knowledge in e-learning context selection

Formal consideration of the links between students' Motivation, Self-Assessment abilities and Tacit Knowledge is shown in this paper to provide a useful model (MSATK) for planning postgraduate, Web-based education. The design of effective e-Learning courses requires a Learning Framework that emphasizes contextanalysis within knowledge-mediated processes. Contextual analysis ensures that self-assessment will be effective in complex domains that rely on Web sources of experiential knowledge, usually accessible as Professional practice models that employ diagnostic tools for scenario simulation processes. Demographic trends now facing Japan and Western countries, and the knowledge management support requirements of global e-Learning initiatives are challenging the value of current selfassessment processes. Building a Culture of Critique is highly desirable, but the lack of an Learning Framework that reflects student ownership of their learning process has obscured the need for tools to correctly interpret domain contexts, or for student freedom to drive the need for modified scenarios. The value of a Learning Framework that links motivation, tacit knowledge, selfassessment practice and contextual analysis is examined in this paper with consequential implications for Web support.

Baozou manhua (rage comics), internet humour and everyday life

Wang Nima launched baozoumanhua.com in 2008 to introduce rage comics (baozou manhua) to China after noticing its popularity in the USA. The emergence of baozou manhua signifies a new form of expression for ordinary netizens where they move from simply being consumers of comics to producers, combining image and text in a humorous way and distributing them via a wide variety of communication tools. This paper examines how the genre of baozou manhua enables Chinese netizens to vent about their everyday experiences and frustrations of daily life. It also explores how computer software technology and the Internet have influenced contemporary Chinese visual humour by focusing on the baozoumanhua.com Internet community. Although baozou manhua is an Internet phenomenon emerging from the specific sociopolitical context of contemporary China, examining this form of expression not only sheds light on popular online culture in China and the issues Chinese netizens grapple with but also provides an understanding of how digital visual culture changes across time and space as North American rage faces circulate around the world and garner new meaning after being appropriated and reinterpreted in the ‘interpretative community’ of Chinese cyberspace.

The Vulture Club: international newsgathering via Facebook

Facebook is celebrating its 10th anniversary in 2014. Like its social media cousin, Twitter, Facebook has transformed how journalists gather and disseminate international news. On Facebook, freelance journalists work together in open and closed communities to share information about news production in the latest crisis news datelines. One such community is the Vulture Club. This 'secret' site is being used to garner resources that previously were available only to mainstream staff correspondents. The majority of the posts on this site seek advice on good fixers, visas, safety gear, hotels and contacts. This article uses content analysis to examine posts on the VC site. It concentrates in particular on requests by freelance journalists for help with finding fixers in different countries. The study compares this model to a previous research study on staff correspondents and fixers. The findings are theorised by employing the work of Pierre Bourdieu on the acquisition of social and cultural capital. 

Online health information seeking: How people with multiple sclerosis find, assess and integrate treatment information to manage their health

Background and objective: The Internet is increasingly prominent as a source of health information for people with multiple sclerosis (MS). But there has been little exploration of the needs, experiences and preferences of people with MS for integrating treatment information into decision making, in the context of searching on the Internet. This was the aim of our study. Design: Sixty participants (51 people with MS; nine family members) took part in a focus group or online forum. They were asked to describe how they find and assess reliable treatment information (particularly online) and how this changes over time. Thematic analysis was underpinned by a coding frame. Results: Participants described that there was both too much information online and too little that applied to them. They spoke of wariness and scepticism but also empowerment. The availability of up-to-date and unbiased treatment information, including practical and lifestyle-related information, was important to many. Many participants were keen to engage in a 'research partnership' with health professionals and developed a range of strategies to enhance the trustworthiness of online information. We use the term 'self-regulation' to capture the variations in information seeking behaviour that participants described over time, as they responded to their changing information needs, their emotional state and growing expertise about MS. © 2014 John Wiley & Sons Ltd.

Because it takes a village to fund the answers: Crowdfunding University Research

Whichever way you look at it, online crowdfunding is ramifying. From its foundations supporting creative industry initiatives, crowdfunding has branched into almost every aspect of public and private enterprise. Niche crowdfunding platforms and models are burgeoning across the globe faster than you can trill “kerching”. Early adopters have been quick to discover that in addition to money, they also get free market information and an opportunity to develop a relationship with their market base. Despite these evident benefits, universities have been cautious entrants in the crowdfunding space and more generally in the emerging ‘collaborative economy’ (Owyang, 2013). There are many cultural and institutional legacies that might explain this reluctance. For example, to date universities have achieved social (and economic) distinction through refining a set of exclusionary practices including, but not limited to, versions of gatekeeping, ranking and credentialing. These practices are reproduced in the expected behaviors of individual academics who garner social currency and status as experts, legislators and interpreters (Osborne, 20014: 435). Digitalization and the emergent knowledge and collaboration economies, have the potential to disrupt the academy’s traditional appeals to distinction and to re-engage universities and academics with their public stakeholders. This chapter will examine some of the challenges and benefits arising from public micro-funding of university-based research initiatives during a period of industrial transition in the university sector.Broadly then this chapter asks; what does scholarship mean in a digital ecosystem where sociality (rather than traditional systems for assessing academic merit) affords research opportunity and success? How might university research be rethought in a networked world where personal and professional identities are blurred? What happens when scholars adopt the same pathways as non-scholars for knowledge discovery, development and dissemination through use of emerging practices such as crowdfunding. These issues will be discussed through detailed exploration of a successful pilot project to crowdfund university research; Research My World. This project, a collaboration between Deakin University and the crowdfunding platform pozible.com, set out to secure new sources of funding for the ‘long-tail’ of academic research. More generally, it aimed to improve the digital capacity of the participating researchers and create new opportunities for public engagement for the researchers themselves as well as the university. We will examine how crowdfunding and social media platforms alter academic effort (the dis-intermediation or re-intermediation of research funding, reduction of the compliance burden, opportunities for market validation and so on), as well as the particular workflows of scholarly researchers themselves (improvements in “digital presence-building”, provision of cheap alternative funding, opportunities to crowdsource non-academic knowledge). In addressing these questions, this chapter will explore the influence that crowdfunding campaigns have for transforming contemporary academic practices across a range of disciplinary instances, providing the basis for a new form of engagement-led research. To support our analysis we will provide an overview of the initiative through quantitative analysis of a dataset generated by the first iteration of Research My World projects.

Nutrition competencies in health professionals' education and training: a new paradigm

Most health care professionals are not adequately trained to address diet and nutrition-related issues with their patients, thus missing important opportunities to ameliorate chronic diseases and improve outcomes in acute illness. In this symposium, the speakers reviewed the status of nutrition education for health care professionals in the United States, United Kingdom, and Australia. Nutrition education is not required for educating and training physicians in many countries. Nutrition education for the spectrum of health care professionals is uncoordinated, which runs contrary to the current theme of interprofessional education. The central role of competencies in guiding medical education was emphasized and the urgent need to establish competencies in nutrition-related patient care was presented. The importance of additional strategies to improve nutrition education of health care professionals was highlighted. Public health legislation such as the Patient Protection and Affordable Care Act recognizes the role of nutrition, however, to capitalize on this increasing momentum, health care professionals must be trained to deliver needed services. Thus, there is a pressing need to garner support from stakeholders to achieve this goal. Promoting a research agenda that provides outcome-based evidence on individual and public health levels is needed to improve and sustain effective interprofessional nutrition education.

Social presence – connecting pre-service teachers as learners using a blended learning model

The national reform agenda for early childhood education and care across Australia has led to an increased demand for qualified early childhood teachers. In response, universities have developed innovative approaches in delivering early childhood teacher educa tion courses designed to support existing diploma qualified educators to gain their teaching qualifications. One such course at a major Australian University incorporated a flexible multi-modal option of study which included community -based, on line e-learning and face -to- face intensive tutorials. This paper reports on a study examining the outcomes for students undertaking their studies using this course delivery mode. The study sought to examine the students’ perceptions of the efficacy of the teaching and learning approach in meeting their learning needs, and the factors that were most influential in informing these perceptions. The findings indicated that it was the inclusion of contact and a social presence in the online learning environment which was most influential.

Universal Design in Higher Education

While colleges and universities increasingly draw upon the concept of Universal Design to create an ideal learning environment, it can be challenging to apply the concept practically in the classroom. This project explores innovative ways to incorporate Universal Design into campus architecture, classroom technology and curriculum development. Further, this brief describes different approaches used by universities to garner faculty interest and offer effective training in Universal Design.
