This research project explores teachers’ beliefs about what constitutes 21st century literacy learning environments, what they perceive to be the literacy practices Year 6 students need to be exposed to now, compared to what they may require in the future, how this learning is enacted, and some of the factors that influence their pedagogical practices and decision-making. The thesis employed both narrative inquiry and hermeneutic phenomenology approaches to collect, interpret and present the stories from the research participants. The findings offer insights into teacher practices and decision-making concerning literacy in and for the 21st century.

Confronted with increasing anthropogenic change, conservation in the 21st century requires a sound understanding of how ecological systems change during disturbance. We highlight the benefits of recognizing two distinct components of change in an ecological unit (i.e., ecosystem, community, population): 'resistance', the ability to withstand disturbance; and 'resilience', the capacity to recover following disturbance. By adopting a 'resistance-resilience' framework, important insights for conservation can be gained into: (i) the key role of resistance in response to persistent disturbance, (ii) the intrinsic attributes of an ecological unit associated with resistance and resilience, (iii) the extrinsic environmental factors that influence resistance and resilience, (iv) mechanisms that confer resistance and resilience, (v) the post-disturbance status of an ecological unit, (vi) the nature of long-term ecological changes, and (vii) policy-relevant ways of communicating the ecological impacts of disturbance processes.

This paper reports on a study that investigated pre-service teachers’ digital funds of knowledge and their perceptions of the digital pedagogies and practices in early years literacy classrooms. It also explores pre-service teachers’ experiences of “produsing” a cumulative multimodal portfolio (in the form of a wiki) and its application for future literacy teaching and learning. Specifically, 123 education students enrolled in their second year of an undergraduate initial-teacher education course at an Australian university completed an anonymous survey. The resultsshow that this group of students were active users of technology-based tools, but had limited experience with using participatory user-led knowledge creation tools (such as Web 2.0 technologies) although many observed the use of these tools in early years literacy classrooms while on professional experience school placements. Further findings show thatalthough the majority of this group of pre-service teachers felt more confident after creating a wiki and reported that they would use them in future literacy teaching and learning, their understandings of the pedagogical and creative potential of these digital tools in supporting literacy learning in young children appeared limited. The findings suggest that there is a need for educators in higher education to understand their students’ digital funds of knowledge and to provide rich opportunities to support these students’ use and understandings of the affordances of these new technologies as vehicles to explore and enrich 21st century literacy learning in early years digital environments.

In the 21st century young people live and learn in a technological world that is fast paced and in a constant state of change. As technology becomes more and more accessible outside of the classroom,educators are challenged to re-consider the literacy skills required to be successfully literate. Enacting literacy teaching and learning in and for the 21st century requires teachers to update their pedagogicalknowledge, skills and contextual understanding of the world children live and learn in. This chapter offers a brief overview of the Australian Curriculum, locating it within a 21st century learning discourse.The authors interpret and analyse one young student’s creation of a digital text in a movie modality. Attention is paid to how the case study teacher created meaningful digital literacy learning experiences and opportunities for children to create and interact in social, multimodal textual environments, both within and beyond the school.

Functional and nutraceutical foods provide an opportunity to improve one's health by reducing health care costs and to support economic development in rural communities. For this reason, various phyto-based functional foods are becoming popular worldwide owing to number of evidences for their safer therapeutic applications. Garlic (Allium sativum L.,) is an essential vegetable that has been widely utilized as seasoning, flavoring, culinary and in herbal remedies. The consumption of traditional plants especially garlic has progressively increased worldwide because of their great effectiveness, fewer side effects and relatively low cost. Garlic is well known to contain an array of phytochemicals. These bioactive molecules are playing pivotal role in maintaining human health and having potential to reduce various ailments. It has distinct nutritional profile with special reference to its various bioactive components that can be used in different diet based therapies to cure various life-style related disorders. The present review is an attempt to explore the functional/nutraceutical role of garlic against various threats including dyslipidemia and hyperglycemia, cardiovascular disorders, antioxidant capacity and carcinogenic perspectives.

BACKGROUND: We sought to provide a contemporary picture of the presentation, etiology, and outcome of infective endocarditis (IE) in a large patient cohort from multiple locations worldwide. METHODS: Prospective cohort study of 2781 adults with definite IE who were admitted to 58 hospitals in 25 countries from June 1, 2000, through September 1, 2005. RESULTS: The median age of the cohort was 57.9 (interquartile range, 43.2-71.8) years, and 72.1% had native valve IE. Most patients (77.0%) presented early in the disease (<30 days) with few of the classic clinical hallmarks of IE. Recent health care exposure was found in one-quarter of patients. Staphylococcus aureus was the most common pathogen (31.2%). The mitral (41.1%) and aortic (37.6%) valves were infected most commonly. The following complications were common: stroke (16.9%), embolization other than stroke (22.6%), heart failure (32.3%), and intracardiac abscess (14.4%). Surgical therapy was common (48.2%), and in-hospital mortality remained high (17.7%). Prosthetic valve involvement (odds ratio, 1.47; 95% confidence interval, 1.13-1.90), increasing age (1.30; 1.17-1.46 per 10-year interval), pulmonary edema (1.79; 1.39-2.30), S aureus infection (1.54; 1.14-2.08), coagulase-negative staphylococcal infection (1.50; 1.07-2.10), mitral valve vegetation (1.34; 1.06-1.68), and paravalvular complications (2.25; 1.64-3.09) were associated with an increased risk of in-hospital death, whereas viridans streptococcal infection (0.52; 0.33-0.81) and surgery (0.61; 0.44-0.83) were associated with a decreased risk. CONCLUSIONS: In the early 21st century, IE is more often an acute disease, characterized by a high rate of S aureus infection. Mortality remains relatively high.

This article argues that 'traditional mateship', as the everyday practice of men's same-sex friendships, is a dying mode of relating in Australian culture. Using Goffman's dramaturgical model, the views of three generations of men are used to qualitatively explore three proposed sites of transformation in men's same-sex friendships. First, the shift from unquestioning group loyalty to individualistic, transient and contingent relationship choice; second, the move from guarded levels of disclosure to open expressiveness and willingness to display vulnerability; and finally the evolution from expecting and giving only practical support to providing both practical and emotional support. The narratives of the middle-aged cohort are used to illustrate the various role-distance strategies that were used to resist and rework gender scripts. The article concludes that, although the parameters of acceptable gendered behaviours in Australian men's friendships are expanding, they have not yet reached the breadth and depth found in 'pure' friendships, but could be described as a new type of mateship: neo-mateship.

In Fiction in the Age of Photography[i], Nancy Armstrong examines the impact of photography on the way in which the nineteenth century novelists represented society. In particular she asks 'But what do we make of the fact that the novel's turn to pictorialism coincided with the sudden ubiquity of photographic images in the culture at large? Why did pictures begin to speak louder than words?

This thesis is an investigation of the relevance of ‘people's war’ to contemporary Chinese defence policy. This loose concept has been eroded by 'modernity’, but a guerilla-based defence remains the essential theme. Prior to China's acquisition of nuclear weapons, people's war was the sole element of the state's deterrent policy, aiming to swamp an invader with China's numerical strength. In the 1980s and beyond people's war finds effectiveness through a combination of materiel of middle range technology and the traditional usage of massive manpower. People's war under modern conditions remains essentially defensive, but now incorporates 'active defence’ with accent on greater mobility. However, the central thesis of this work relates to how the traditional strategy may influence nuclear doctrine. This thesis proposes that China could abandon long-range ballistic missiles and adopt a new concept in nuclear strategy: that of, Guerilla Nuclear Warfare. Trained in guerilla tactics and equipped with battlefield nuclear weapons, this would represent the logical extension of China's people's war strategy to the new nuclear conditions associated with superpower research into space-based ballistic missile defences and which, in full deployment, could nullify a Chinese nuclear deterrent based only on 'mid-tech' delivery systems. Guerilla Nuclear Warfare, as a strategy, would involve the irregular use of locally held and controlled tactical nuclear weapons, but it would also be a method of circumventing the proposed Soviet missile defence shield by not challenging it. Guerilla Nuclear Warfare does not exist in the late 1980s, but evidence exists to suggest its development. It cannot yet be proven as the new direction but China's strategic circumstances add weight to available indications: unless the Strategic Defence programs of the established superpowers are arrested then it appears the sole option available to the Chinese for the maintenance of a nuclear deterrent in the early part of the 21st Century.

This paper brings together some of the main scholarly sources and thinkers of the last fifty years or so, who have been influential in the corporate social responsibility discussions which have become important, once again, as we begin the 21st century. The author creates a narrative ofkey social, economic and political concepts and themes, which are rationalised (in ways that others might not) from what is often a very disparate, diverse and not always connected discussion on corporate social responsibility. This is not an objective history, charting the developments chronologically, but is the bringing together ofsome serious thinking in the field of corporate social responsibility in a way which has considerable resonance JOT both the development of public policy and business practice in corporate citizenship at the beginning ofthe 21st century.

Contemporary theorists are opening new ways to think about public relations. Public relations textbook authors have hitherto borrowed theories from the adjacent disciplines of communication, psychology, sociology, and organisation studies. At the end of the twentieth century, J. Grunig’s four-model concept of public relations was the only modern theoretical approach that could be said to have originated from within public relations scholarship. And as we will see, even J. Grunig’s perspective is rooted in political theory. But the 21st century’s burgeoning critical and professional interest in ethical public relations has produced a flurry of discipline-specific, theoretical initiatives.

This paper will develop a discussion about caring as a modern mental health nurse. We argue that the demands of mental health nursing today extend beyond the more traditional skills of care and caring. We believe that in order to meet mental health needs in the 21st century that caring should be extended to encompass the additional expertise of emotional intelligence and resilience. Emotional intelligence, resilience, and resilient behaviours have the potential to assist individuals to transcend negative experiences and transform these experiences into positive self-enhancing ones. This has implications for improved consumer outcomes through role-modelling and educational processes, but also may hold implications in supporting a strong workforce in mental health.
