Tongan adolescents' eating patterns : opportunities for intervention

The purpose of this mixed methods study was to examine the sources of food and dietary patterns of Tongan adolescents (n = 2084) and their perceptions of sociocultural influences. The study incorporated anthropometric measurements, a behavioral survey, and qualitative interviews. More adolescent Tongan females (82.5%) than males (74.3%) reported sourcing morning tea and/or lunch (females 81.9%, males 72.6%) from school canteens or nearby food outlets. More females than males reported consuming obesity-promoting foods such as packaged snack foods (females 38.2%, males 21.3%), chocolates (females 24.7%, males 15.0%), and soft drinks (females 55.3%, males 50.4%). Food purchased for consumption at schools was predominantly energy dense and nutrient poor. Ensuring that students have access to foods of high nutritional quality sourced from school or home, and restricting access to local food outlets that supply unhealthy products would improve the nutrition status of adolescents in Tonga. Furthermore, it is important that obesity prevention interventions are informed by culture-specific influences to optimize uptake of healthy diets.

Students' and teachers' use of ICT in primary mathematics

This paper reports on the findings of a research project that investigated the use of Information and Communication Technologies (ICT) in Primary mathematics in an urban and rural network. Surveys and semi structured interviews were held to obtain insight into teachers’ and students’ perceptions and attitudes towards the usage of ICT in the teaching and learning of mathematics. The presentation will highlight the findings and include a discussion on the types of ICT that students use in and out of school to learn mathematics.

Using action research to improve the quality of teaching in basic education in remote schools in PNG.

This paper discusses the use of action research with teachers in remote primary schools in PNG to provide sustainable professional learning to help improve the quality of schooling. It arises from an ADRA research project being undertaken by the authors. The paper describes the project’s research design and its implementation to investigate the introduction, implementation and feasibility of teachers using action research to solve their own problems related to providing basic education in remote communities. If successful, action research may prove to be an effective approach to sustaining professional learning communities in locations where traditional approaches and means of professional development are difficult or impossible to sustain.

The paper describes the research team’s approach to identifying and engaging schools in remote districts of Western and East Sepik provinces, surveying teachers in those districts about their professional learning needs and circumstances, identifying schools to trial action research, and to undertake the fieldwork to implement action research and to study its implementation. The teachers’ experiences with using action research are presented in the context of their particular research topics chosen for their school. To date, the findings suggest that teachers can use action research to help them improve the quality of the education they provide for children. However, the initiation and sustainability of such an action research approach is influenced by the capacities and commitment of head teachers and standards officers, in particular, valuing and understanding reflective practice and action research for professional learning in school communities.

An insect-based approach to robotic homing

Many animals, including insects, successfully engage in visual homing. We describe a system that allows a mobile robot to home. Specifically we propose a simple extension to our original homing scheme which significantly improves its performance by incorporating a richer view of the environment. The addition of landmark apparent-size cues assists homing by providing a more robust homing vector as well as providing a simple and effective method of reinforcing landmark avoidance. The homing algorithm allows a mobile robot to incrementally home by moving in such a way as to gradually reduce the discrepancy between the current view and the view obtained from the home position. Both simulation and mobile robot experiments are used to demonstrate the feasibility of this approach. By matching the bearings of features extracted from panoramic views and using a vector summation technique to compute a homing vector we are able to provide a simple, parsimonious and robust robotic homing algorithm.

Visual networking : Australia's media landscape

Australia is in the midst of a massive transformation of its communication infrastructure. The AUD43 billion Australian National Broadband Network (NBN) to be set up by the wholly Federal government-owned NBNCo Limited (NBNCo), is the largest infrastructure project ever proposed in Australia (NBN, 2010). It has the capacity to combine features and technologies that were once separate, but now have converged, including computing, telephony, free-to-air (FTA) television, direct-to-home satellite broadcasting, radio and the internet. This means that current thinking about these media technologies, developed through the process of convergence as well as regulation, requires review. Future services for digital television are going to be more akin to app-based functions currently available on mobiles and tablets but accessed via the television screen rather than the PC. Against such a background, this article examines the Australian ‘televisual’ space, arguing that faster broadband and internet-enabled televisions for movies, shows, communication and more, when it suits the audience, are the keys to television’s survival through visually networked possibilities.

Tim O'Reilly and web 2.0 : the economics of memetic liberty and control

This article presents an account of the role of Tim O'Reilly, both as an individual and as a corporate entity (O'Reilly Group), in the creation, spread and use of the concept of Web 2.0. It demonstrates that, whatever Web 2.0's current uses to describe variously the technologies, politics, commerce or social meaning of the Internet, it originates as a deliberately open signifier of novel and potential internet development in the mid-2000s. The article argues that O'Reilly has promoted the diversity of the term's meanings and uses - celebrating textual liberties - but has also emphasised the special role that O'Reilly plays in providing the authoritative definition of that term. In essence, O'Reilly profits from this 'control' of the idea of Web 2.0 but that, to enjoy that control O'Reilly must also allow differences in meaning. The article concludes by suggesting that Web 2.0 therefore signifies a new kind of economics that brings together freedom and control in a new way.

Youth and the communication of Risk: developing connections between cancer council Australia and contemporary online youth culture

Through two focus groups, the project investigated how youth culture perceives online communication of risk. In two 90-minute sessions, investigators gaged the range of online activities that nine 18 - 24 year old university students engaged with. Through a guided discussion the participants explored how they would relate to the communication of health risk more generally and cancer risk more specifically.
Participants’ online activity is very high and a range of social media forms are part of their everyday lives. In contrast, their use of traditional media is almost non-existent. Their relationship to accessing and being aware of health information demonstrated a range of views that pointed to quite new and different relationships to health and health professionals. To intersect with their online movements in the communication of health risk demands a sophisticated knowledge of their own searching patterns.
Key ideas generated from the focus groups include: that it might be advantageous to group health risk beyond the specificity of cancer for online success; that an online persona would be useful to provide a face for the communication of risk; that a multi-platform campaign to raise the profile of a persona would be useful; and that success means moving between the serious and the light-hearted in a way that makes the persona a complete person of interest for them.

A fuzzy technique to control congestion in WSN

Congestion in wireless sensor networks (WSNs) is a crucial issue. That is due to the relatively high node density and source-to-sink communication pattern. Congestion not only causes packet loss, but also leads to excessive energy consumption as well as delay. Therefore, in order to prolong network lifetime and improve fairness and provide better quality of service, developing a novel solution for congestion estimation and control is important to be considered. To address this problem, we propose a type-2 fuzzy logic based algorithm to detect and control congestion level in WSNs. The proposed algorithm considers local information such as packet loss rate and delay to control congestion in the network. Simulation results show that our protocol performs better than a recently developed protocol in prolonging network lifetime as well as decreasing packet loss.

Communicating with nurses: the experiences of 10 individuals with an acquired severe communication impairment

Successful communication is integral to quality health care and successful nursing practice. Ten people who had been in hospital in the 12 months prior to the study and who had no functional speech at that time were interviewed about their communication experiences with nurses. Overall, these individuals experienced difficulties, some of which appeared to be related to a lack of augmentative and alternative communication (AAC) resources and a lack of knowledge of AAC among nurses. In addition, the participants noted that nurses did not always have the time or the skills to communicate effectively with them. The participants suggested strategies to improve communication interactions between patients with no or limited functional speech and nurses. These strategies include pre-admission briefing and training nurses about effective strategies for communicating with patients who are unable to speak, including the use of augmentative and alternative communication systems.

Nursing the patient with severe communication impairment

Background. Effective communication with patients is critical to effective nursing practice. Surprisingly, there is little information on nurses' experiences in caring for patients who are unable to speak. Purpose and method. This study provides descriptive information from interviews with 20 nurses who cared for patients with severe communication impairment. The interview protocol explored positive and negative experiences of nursing patients with severe communication impairment. Frequency counts and descriptive analyses were conducted to identify the major themes emerging from the interviews. Results. The results suggest that nurse-patient communication is difficult when the patient has severe communication impairment, although some nurses discovered effective strategies to facilitate communication with such patients. Many of the difficulties could be viewed as a breakdown in understanding arising from the lack of a readily interpretable communication system that could be used by nurse and patient. Conclusions. The results suggest a need for training nurses in the use of alternative modes of communication. Nurses also need access to a variety of simple augmentative communication devices for use with patients who are unable to speak. Finally, nurses should collaborate with speech pathologists on the development of preadmission information and bedside training for people who are admitted to hospital with severe communication impairment.

Consumer socialization agency: implications for family decision-making about holidays

This paper investigates the influence young adult children living at home have over parents' holiday decisions. "Consumer socialization agency" (CSA) was developed as a measure to capture the intercession or mediation one person accepts from another person about consumption issues. The analysis was conducted through a dyadic method, which involves collecting data from and analyzing data about pairs of people (dyads); in this case, parents and their children. CSA was related to family size and gender+ but more closely related to family communication style. Families fostering an open, issue-based communication style seem to have the highest likelihood of children socializing parents. © 2014 © 2014 Taylor & Francis.

Medication communication through documentation in medical wards: knowledge and power relations

Health professionals communicate with each other about medication information using different forms of documentation. This article explores knowledge and power relations surrounding medication information exchanged through documentation among nurses, doctors and pharmacists. Ethnographic fieldwork was conducted in 2010 in two medical wards of a metropolitan hospital in Australia. Data collection methods included participant observations, field interviews, video-recordings, document retrieval and video reflexive focus groups. A critical discourse analytic framework was used to guide data analysis. The written medication chart was the main means of communicating medication decisions from doctors to nurses as compared to verbal communication. Nurses positioned themselves as auditors of the medication chart and scrutinised medical prescribing to maintain the discourse of patient safety. Pharmacists utilised the discourse of scientific judgement to guide their decision-making on the necessity of verbal communication with nurses and doctors. Targeted interdisciplinary meetings involving nurses, doctors and pharmacists should be organised in ward settings to discuss the importance of having documented medication information conveyed verbally across different disciplines. Health professionals should be encouraged to proactively seek out each other to relay changes in medication regimens and treatment goals.

A metasynthesis of patient-provider communication in hospital for patients with severe communication disabilities: informing new translational research

Poor patient-provider communication in hospital continues to be cited as a possible causal factor in preventable adverse events for patients with severe communication disabilities. Yet to date there are no reports of empirical interventions that investigate or demonstrate an improvement in communication in hospital for these patients. The aim of this review was to synthesize the findings of research into communication in hospital for people with severe communication disabilities arising from lifelong and acquired stable conditions including cerebral palsy, autism, intellectual disability, aphasia following stroke, but excluding progressive conditions and those solely related to sensory impairments of hearing or vision. Results revealed six core strategies suggested to improve communication in hospital: (a) develop services, systems, and policies that support improved communication, (b) devote enough time to communication, (c) ensure adequate access to communication tools (nurse call systems and communication aids), (d) access personally held written health information, (e) collaborate effectively with carers, spouses, and parents, and (f) increase the communicative competence of hospital staff. Currently there are no reports that trial or validate any of these strategies specifically in hospital settings. Observational and evaluative research is needed to investigate the ecological validity of strategies proposed to improve communication.

Nursing educator perspectives of overseas qualified nurses' intercultural clinical communication: barriers, enablers and engagement strategies

AIMS AND OBJECTIVES: To understand the intercultural communication experiences and associated communication training needs of overseas qualified nurses in the Australian healthcare system from the unique perspectives of nurse educators teaching in accredited bridging programmes. BACKGROUND: Overseas qualified nurses are an integral part of the nursing workforce in migration destination countries. Communication training needs are more complex when there are cultural, ethnic and language differences between nurses, other health professionals and patients. DESIGN: A qualitative, exploratory research design using semi-structured interviews. METHODS: All (nine) organisations involved in conducting the Australian Health Practitioner Regulation Agency approved preregistration bridging programmes for overseas qualified nurses within the state of Victoria, Australia, were involved in the study. Participants were 12 nurse educators employed in these organisations. Thematic analysis was undertaken. RESULTS: Three macro themes emerged about the overseas qualified nurses' intercultural communication: (1) pre-existing barriers and enablers to intercultural communication, for example, nurses' reluctance to engage in communicative strategies that build rapport with patients, (2) transitional behaviours and impact on communication, including maintenance of perceived cultural hierarchies between health professionals and (3) development of communicative competence, including expanding one's repertoire of conversational gambits. CONCLUSIONS: The findings point to the domains and causes of communication challenges facing overseas qualified nurses in new healthcare settings as well as strategies that the nurse educators and nurses can adopt. Communication cannot be merely regarded as a skill that can be taught in a didactic programme. Comprehensive understanding is needed about the sociocultural dimensions of these nurses' orientation, which can impact on how they communicate in their new healthcare settings. RELEVANCE TO CLINICAL PRACTICE: The findings can act as triggers for discussion with overseas qualified nurses and other health professionals to raise awareness about the aspects of intercultural communication and to debate alternative viewpoints and explanations. They can also inform changes in the structure and content of the bridging programmes.

Geo-identity, urban school choice and education campaigns for public schools

Educational campaigning has received little attention in the literature. This study investigates long-term and organised urban campaigns that are collectively lobbying the Victorian State Government in Australia, for a new public high school to be constructed in their suburb. A public high school is also known as a state school, government school, or an ordinary comprehensive school. It receives the majority of its funding from the State and Federal Australian Government, and is generally regarded as ‘free’ education, in comparison to a private school. Whilst the campaigners frame their requests as for a ‘public school’, their primary appeal is for a local school in their community. This study questions how collective campaigning for a locale-specific public school is influenced by geography, class and identity. In order to explore these campaigns, I draw on formative studies of middle-class school choice from an Australian and United Kingdom perspective (Campbell, Proctor, & Sherington, 2009; Reay, Crozier, & James, 2011). To think about the role of geography and space in these processes of choice, I look to apply Harvey’s (1973) theory of absolute, relational and relative space. I use Bourdieu (1999b) as a sociological lens that is attentive to “site effects” and it is through this lens that I think about class as a “collection of properties” (Bourdieu, 1984, p. 106), actualised via mechanisms of identity and representation (Hall, 1996; Rose, 1996a, 1996b). This study redresses three distinct gaps in the literature: first, I focus attention on a contemporary middle-class choice strategy—that is, collective campaigning for a public school. Research within this field is significantly under-developed, despite this choice strategy being on the rise. Second, previous research argues that certain middle-class choosers regard the local public school as “inferior” in some way (Reay, et al., 2011, p. 111), merely acting as a “safety net” (Campbell, et al., 2009, p. 5) and connected to the working-class chooser (Reay & Ball, 1997). The campaigners are characteristic of the middle-class school chooser, but they are purposefully and strategically seeking out the local public school. Therefore, this study looks to build on work by Reay, et al. (2011) in thinking about “against-the-grain school choice”, specifically within the Australian context. Third, this study uses visual and graphic methods in order to examine the influence of geography in the education market (Taylor, 2001). I see the visualisation of space and schooling that I offer in this dissertation as a key theoretical contribution of this study. I draw on a number of data sets, both qualitative and quantitative, to explore the research questions. I interviewed campaigners and attended campaign meetings as participant observer; I collected statistical data from fifteen different suburbs and schools, and conducted comparative analyses of each. These analyses are displayed by using visual graphs. This study uses maps created by a professional graphic designer and photographs by a professional photographer; I draw on publications by the campaigners themselves, such as surveys, reports and social media; but also, interviews with campaigners that are published in local or state newspapers. The multiple data sets enable an immersive and rich graphic ethnography. This study contributes by building on understandings of how particular sociological cohorts of choosers are engaging with, and choosing, the urban public school in Australia. It is relevant for policy making, in that it comes at a time of increasing privatisation and a move toward independent public schools. This study identifies cohorts of choosers that are employing individual and collective political strategies to obtain a specific school, and it identifies this cohort via explicit class-based characteristics and their school choice behaviours. I look to use fresh theoretical and methodological approaches that emphasise space and geography, theorising geo-identity and the pseudo-private school
