Perceptions of roles and responsibilities in online learning : a case study

The extensive introduction of online technologies to support teaching and learning is impacting how teachers teach and students learn. It is also affecting both teaching staff’s and students’ perceptions of what each others’ roles are. The research reported here is part of a larger study that explored different aspects of teaching and learning in online environments. This study was undertaken within an Australian university and involved an institution-wide survey of students. The paper reports on students’ perceptions of their roles as online learners and the expectations they have of online teachers. The outcomes of the research suggest that different cohorts of students have different expectations. These expectations are informed by their mode of study and also by their perceptions of how staff engage with online teaching. Recommendations include proactive management of student expectations by staff, as well as a commitment by staff to meet those expectations.

Gambling and corporate social responsibility (CSR) : re-defining industry and state roles on duty of care, host responsibility and risk management

During the 1990s, states embraced legalised gambling as a means of supplementing state revenue. But gaming machines (EGMs, pokies, VLTs, Slots) have become increasingly controversial in countries such as Australia, Canada and New Zealand, which experienced unprecedented roll-out of gaming machines in casino and community settings; alongside revenue windfalls for both governments and the gambling industry. Governments have recognised that gambling results in a range of social and economic harms and, similar to tobacco and alcohol, have introduced public policies predicated on harm minimisation. Yet despite these, gaming losses have continued to climb in most jurisdictions, along with concerns about gambling-related harms. The first part of this article discusses an emerging debate in Ontario Canada, that draws parallels between host responsibility in alcohol and gambling venues. In Canada, where government owns and operates the gaming industry, this debate prompts important questions on the role of the state, duty of care and regulation ‘in the public interest’ and on CSR, host responsibility and consumer protection. This prompts the question: Do governments owe a duty of care to gamblers?

The article then discusses three domains of accumulating research evidence to inform questions raised in the Ontario debate: evidence that visible behavioural indicators can be used with high confidence to identify problem gamblers on-site in venues as they gamble; new systems using player tracking and loyalty data that can provide management with high precision identification of problem gamblers and associated risk (for protective interventions); and research on technological design features of new generation gaming products in interaction with players, that shows how EGM machines can be the site for monitoring/protecting players. We then canvass some leading international jurisdictions on gambling policy CSR and consumer protection.

In light of this new research, we ask whether the risk of legal liability poses a tipping point for more interventionist public policy responses by both the state and industry. This includes a proactive role for the state in re-regulating the gambling industry/products; instituting new forms of gaming machine product control/protection; and reinforcing corporate social responsibility (CSR) and host responsibility obligations on gambling providers – beyond self-regulatory codes. We argue the ground is shifting, there is new evidence to inform public policy and government regulation and there are new pressures on gambling providers and regulators to avail themselves of the new technology – or risk litigation

Swapping roles or swapping desks? When experienced practitioners become students on placement

The social work education literature on the preparation of students for their first practice learning placement, and the support needs of such students once in placement, tend to include implicit assumptions that the students being placed are novice practitioners, with little experience of working in social welfare agencies. Although there are some students for whom these assumptions are undoubtedly correct, another common phenomenon is that practice experience often leads to practitioners enrolling in professional degrees to qualify as a social worker. As credit for prior work experience in social welfare settings has only recently become possible for Australian social work students, we routinely work with aggrieved students who believe they should be exempted from placements, some of whom subsequently find the transition from experienced practitioner to student on placement somewhat difficult. This paper reports on a study which sought to explore the specific needs of experienced practitioners who become social work students on practice learning placements, with the aim of developing procedural recommendations for the placement and support of such students in the future. One of our findings was that several of the students continued to identify as practitioners, albeit in a different agency or programme from their normal place of employment, rather than take on the student identity. The implications of this for the development of practice learning opportunities for students who are experienced practitioners will be discussed.

Suppressors of cytokine signaling : functions in normal biology and roles in disease

Suppressor of cytokine signaling (SaCS) proteins have been identified as key negative regulators of cytokine and growth factor signaling. Therefore, given the diverse roles played by cytokines and growth factors in development and disease, it is not surprising that the sacs proteins themselves possess equally diverse and important functions, such as the control of hematopoiesis, immune function, growth and placental development. Significantly, more recent studies are increaSingly highlighting the crucial roles played by SOCS proteins in disease, particularly their tumor suppressor and anti-infammatory functions. Collectively, this research has served to confirm the importance of this class of proteins and suggests that therapeutic strategies for modulating SOCS proteins might be relevant for a range of diseases.

The roles of social bonds in the Australian tourism network

There is limited published research on the social bonds between employees in two organizations. This paper aims to examine 1) relationships in the Australian tourism industry, 2) the nature and role of social bonds and commercial friendships, 3) the nature and roles of the investments in economic and social resources, and 4) the nature of personal relationships in the tourism network. The perspective and attitudes of the tourism network participants become clear and their vested interests are highlighted. Network pictures are developed for the 5 key sectors of this industry. The adaptations of these sectors are also discussed. The nature and role of social bonds and commercial friendships is examined. The Leximancer program is used to qualitatively analyze interview transcripts. Findings show the centrality of relationships in this industry and the importance of social bonds to the travel agency sector. This study provides additional insight into the nature of social bonds in the development of successful business to business relationships. A discussion of antecedents and outcomes of social bonds will be further developed.

Recent advances on the roles of NO in cancer and chronic inflammatory disorders

Nitric oxide (NO) is a short-life molecule produced by the enzyme known as the nitric oxide synthase (NOS), in a reaction that converts arginine and oxygen into citrulline and NO. There are three isoforms of the enzyme: neuronal NOS (nNOS, also called NOS1), inducible NOS (iNOS or NOS2), and endothelial NOS (eNOS or NOS3). It is now known that each of these isoforms may be expressed in a variety of tissues and cell types. This paper is a review of the current knowledge of various functions of NO in diseases. We discuss in more detail its role in Cancer, the role of NO in myocardial pathophysiology, in central nervous system (CNS) pathologies. Other diseases such as inflammation, asthma, in chronic liver diseases, inflammatory bowel disease (IBD), arthritis, are also discussed. This review also covers the role of NO in cardiovascular, central nervous, pancreas, lung, gut, kidney, myoskeletal and chronic liver diseases (CLD). The ubiquitous role that the simple gas nitric oxide plays in the body, from maintaining vascular homeostasis and fighting infections to acting as a neurotransmitter and its role in cancer, has spurred a lot of interest among researchers all over the world. Nitric oxide plays an important role in the physiologic modulation of coronary artery tone and myocardial function. Nitric oxide from iNOS appears to be a key mediator of such glial-induced neuronal death. The high sensitivity of neurons to NO is partly due to NO causing inhibition of respiration, rapid glutamate release from both astrocytes and neurons, and subsequent excitotoxic death of the neurons.

The roles of object-image relative motion and static depth information in the perception of heading

Investigates visual information that enables human to effectively guide their movement through the environment. This problem is fundamental to the study of human behaviour, since survival is contingent upon the acquisition of resources that lie in different locations throughout the environment.

Workplace education and training : are TAFE teachers prepared for their evolving roles?

The implications of the research are that many TAFE teachers are ill-equipped to perform the roles, that, in the future, may well be expected of them. The reasons for teachers not being competent in a number of areas appear to include a lack of investment in human capital, a lack of adequate teacher training and a lack of relevant staff development contributing to many having neither the knowledge nor the skills to fulfil their evolving roles.

Sustainable workforce reform : case study of Victorian nurse practitioner roles

Nurse practitioner (NP) roles have been identified as a key strategy in the development of a sustainable and responsive health workforce. To date, the focus of research related to NP roles has been on implementation and short-term evaluation of aspects of NP care; however, little is known about the sustainability of NP roles. A major challenge for the
healthcare sector is to demonstrate long-term outcomes of NP care and shift the research focus from individual NPs to the effectiveness of healthcare teams that incorporate NPs. This paper draws on a framework of the following domains of sustainability in primary care: political, institutional, financial–economic, workforce and client (or patient) and applies these domains to NP planning in the Victorian context.
