Digital TV in Australia and the USA: a cross-impact analysis of the adoption and diffusion of digital TV in Australia and the United States

The paper examines the adoption and diffusion of Digital Television (DTV) in Australia and the United States, identifying historical, technical, regulatory, marketing, and other commonalities and differences that appear to be most significant to its adoption, as both countries have experienced a 'sluggish' diffusion and adoption of DTV so far. Using library research and borrowing the cross-impact matrix method from futures research, the authors develop J J events related to the various influences and groups of stakeholders that had shaped the policy making and adoption of DTV. We then carry out a comparative analysis between the two countries to make evident their impacts, strengths, and directions of influence. The authors suggest that the implementation of DTV in these two developed countries appears to be nearly identical. Even though Australian and US broadcasting models are fundamentally different, the diffusion process for DTV is primarily affected by the nature of digital technology and globalisation, two trends that may be diminishing the import of the nation-state in the technology adoption process. The paper concludes that these broader economic and technical events may have greater import to DTV's successful diffusion than do traditional, cultural, and nationalistic factors suggested in earlier comparative broadcast studies.

The media and the development of the tourism industry during the 20th and 21st centuries: an analysis of four noteworthy cases

The aim of this paper was to explore the role of the media within the context of tourism, specifically with regard to how the media has influenced the activities and perceptions of the tourism sector. In this paper, the term ‘media’ is referred to as mass communication, specifically with regard to newspapers, magazines and broadcasting. It is important to gain a better understanding of the ways in which the media has interacted with the tourism sector, as this information can provide practitioners and academics with insights as to how the media can best be employed to benefit stakeholders of the tourism industry. Lessons can be learned from the past so that the experience gained from it can contribute to best practice in the future. In this way, strategies can be developed to minimise the vulnerability of the tourism sector to damaging or erroneous portrayals of it and its activities in the media.
The case study method was used to explore the role of the media within the context of tourism. Four case studies provided insights on this topic. The four case studies were selected based on their diversity, within the context of the tourism sector, and because they covered a considerable period of time. These variables provided the researchers with a wide-ranging perspective on the topic.
The paper firstly focuses on the 1920’s Waiters’ Strike in the resort town of San Sebastián, Spain, and discusses the role of the media in relation to this event. The second case investigates the use of the media as a destination-marketing tool and reflects on an early manipulation of this process by the German authorities in the documentary Olympia, a film produced for the summer Olympics in 1936. The third case study reports on the manner in which the media has created tensions between connoisseurs of fine food and drink and hospitality industry professionals, and its subsequent implications on service quality. The final case investigates the role of the media in reducing demand for hospitality services in Melbourne on New Year’s Eve 2000.
Through an analysis of these diverse, but important case studies, it can be seen that the media has had, and continues to have, an impact on the development of the tourism industry in both positive and negative ways. The limitations of this research are discussed and recommendations are made for further research that will assist in developing a more comprehensive typology of the media’s role in tourism.

Leontief paradox and the role of factor intensity measurement

In contrast with the prediction of the Heckscher-Ohlin (HO) theorem, Leontief (1953) found that the capital-labor ratio embodied in the US exports is smaller than the capital-labor ratio embodied in the US competitive import replacements. In Leontief's analysis, the measured factor content of US imports is computed based on the assumption that all countries are using the US factor intensity techniques. This paper relaxes all assumption of identical factor intensity techniques. It uses an inferring method to infer the factor intensity techniques of different countries based on international relative factor price differences. With the inferred differentiated factor intensity techniques , the Leontief paradox is re-investigated and is found to be either disappeared or eased.

Research designs and scientific identity in marketing journals: review and evaluation

Purpose - This research is based upon the assumption that the empirical research designs and the scientific identity of a journal are related. The objective is to review and evaluate the empirical research design of papers to determine the scientific identity of a selection of academic marketing journals. Design/methodology/approach – The journal sample consists of the Australasian Marketing Journal (AMJ), the European Journal of Marketing (EJM) and the Journal of Marketing (JM). The review and evaluation considers a six-year period, namely 2000-2005. The content analysis consisted of 811 papers. Findings – The scientific identity of JM may be seen as built upon quantitative research designs and the North American paradigm of research values. The scientific identity of AMJ is based upon a mix of empirical research designs and the Australian paradigm of research values. The scientific identity of EJM is also based upon a mix of empirical research designs, but a multi-continental paradigm of research values. Research limitations/implications – The leading continental journals in marketing maintain a scientific identity based upon the continental paradigm of research values. If it is driven to the extremes, a paradigmatic myopia and inertia of research designs may evolve that limit the scientific identity to be dogmatic and narrow-focused rather than variable and broad-focused. Originality/value – A cross-continental eview and evaluation of research designs and scientific identity of academic marketing journals is presented.

Neighborhood walkability and the walking behavior of Australian adults

Background
The physical attributes of residential neighborhoods, particularly the connectedness of streets and the proximity of destinations, can influence walking behaviors. To provide the evidence for public health advocacy on activity-friendly environments, large-scale studies in different countries are needed. Associations of neighborhood physical environments with adults’ walking for transport and walking for recreation must be better understood.

Method
Walking for transport and walking for recreation were assessed with a validated survey among 2650 adults recruited from neighborhoods in an Australian city between July 2003 and June 2004, with neighborhoods selected to have either high or low walkability, based on objective measures of connectedness and proximity derived from geographic information systems (GIS) databases. The study design was stratified by area-level socioeconomic status, while analyses controlled for participant age, gender, individual-level socioeconomic status, and reasons for neighborhood self-selection.

Results
A strong independent positive association was found between weekly frequency of walking for transport and the objectively derived neighborhood walkability index. Preference for walkable neighborhoods moderated the relationship of walkability with weekly minutes, but not the frequency of walking for transport—walkability was related to higher frequency of transport walking, irrespective of neighborhood self-selection. There were no significant associations between environmental factors and walking for recreation.

Conclusions
Associations of neighborhood walkability attributes with walking for transport were confirmed in Australia. They accounted for a modest but statistically significant proportion of the total variation of the relevant walking behavior. The physical environment attributes that make up the walkability index are potentially important candidate factors for future environmental and policy initiatives designed to increase physical activity.

Evaluating a community lifestyle intervention: adherence and the role of perceived support

Background Interventions that increase participation in physical activity and positive dietary changes may improve the health of the community through modifying the lifestyle contribution to preventable disease. However, previous evaluations have identified concerns about inequitable and unsustainable uptake, adherence and retention within healthy lifestyle schemes.

Intervention study The intervention evaluated here was designed to be a 12-week intervention for participants, offering free testing of physiological indicators of health, one-to-one health advice and a range of exercise, activity and cookery classes, at no or reduced cost, at local venues throughout the community. This paper reports the findings from a small qualitative study undertaken to explore the experiences and reflections of those who took part in the intervention to different extents, including those who fully and partially participated as well as those who dropped out or declined to take part.

Method Sixteen respondents took part in semi-structured interviews (5 male, 11 female; 8 black, 8 white; age range 25–85).

Findings The findings suggest that participants assessed the healthy lifestyle intervention in terms of how well it met their pre-existing needs and opportunities for change, and that they selected the aspects of the scheme that suited them, interested them and were perceived as delivering salient results. There is also evidence for a stronger role of perceived support in influencing uptake and maintenance of lifestyle changes, and that support was conceptualised by participants as one of the services offered by the scheme. Perceived support and related perceptions of reliance on the scheme to sustain lifestyle changes also suggested that in some cases full adherence to a scheme is not as likely to produce long-term adherence to lifestyle changes as compared to partial, but more realistic adherence and smaller lifestyle changes. Implications for delivering and evaluating healthy lifestyle interventions are also discussed.

The effect of hook/bait size and angling technique on the hooking location and the catch of recreationally caught black bream Acanthopagrus butcheri

The black bream Acanthopagrus butcheri recreational fishery is the largest estuarine fishery in Victoria. This fishery is managed through legal-minimum length and daily bag limits. The success of this management strategy requires a high survival rate for released fish. Deep-hooking is known to reduce the chance of fish survival after recreational capture and release. This study investigated the potential to reduce deep-hooking and the number of under-size A. butcheri caught by varying angling gear and techniques. Three sizes of long shank hook (small [size 8], medium [size 4] and large [size 1/0]) and two angling techniques (slack line and tight line) were tested for their deep-hooking rates and selectivity characteristics. Increasing the hook size from small to large decreased the likelihood of deep-hooking by 6.6 times (95% CI 2.3–16.3 times). Fishing with a tight line instead of a slack line decreased the chance of deep-hooking by almost 100% (95% CI 0.8–3.6). Fishing with a large hook instead of a small hook significantly (F = 6.71, df = 2, P = <0.001) increased the mean A. butcheri length, although this mean size increase was less than 1 cm. This study was able to identify angling gear and angling technique manipulations that reduced the rate of deep-hooking when targeting A. butcheri in Victorian estuaries.

A comparison of self-reported puberty using the pubertal development scale and the sexual maturation scale in a school-based epidemiologic survey

Purpose: To examine concordance between two self-reported measures of puberty: Sexual Maturatiom Scale (SMS) and Pubertal Developl1!ent Scale (PDS) and their acceptability to adolescents. Methods: Participants of a school-based study in grades 5, 7 and 9 were classified into one of 5 pubertal stages using each method. Results: 2864 students (age 9-16 years) participated. Agreement was moderate for males (K 0.42, 95% CI 0.39,0.45) and females (K 0.57, 95% CI 0.53, 0.61). Concordance within one stage was excellent (females 97%, males 89%), with discrepancies due to females being classified one stage later on the PDS (26%) and males one stage earlier (32%). There were more missing data for the SMS (13%) than the PDS (4%).

The knowledge economy, the techno-preneur and the problematic future of the university

Knowledge economy policies are currently very powerful drivers of change in contemporary university approaches to research. They typically orientate universities to a national innovation system which both positions knowledge as the key factor of economic growth and sees the main purpose of knowledge as contributing to such growth. In this article, the authors explain the economic logic informing such policy interventions in university research and look at the conceptualisation of national innovation systems in various national and international policy sites around the world. Their interest is in what these particular sets of policies have in common, not in how they differ. They introduce three key themes of such systems and the academics they seek to produce. These themes are their techno-scientific orientation, network characteristics and commercial imperatives. The corresponding implied subjects are the techno-scientist, the knowledge networker and the entrepreneur. The authors make the case that evident in such constructions of the future of universities are some unacknowledged and under-acknowledged problems, one of which is a failure to recognise the power of the gift economies of academic culture.

(W)reading, wrangling and the rhythm of the text: enhancing the education of young boys with game-based learning

W)reading, wrangling and the rhythm of the text: enhancing the education of young boys with game-based learning Connecting curriculum content to young people's engagement with texts outside of the classroom is increasingly recognised as a method of providing challenging learning environments (Beavis 1999). The introduction of games-based learning in areas such as literacy provides young people with a structural and conceptual framework with which many, particularly young males, may be familiar...

Environmental art and the production of publics : responding to environmental change

Environmental crises around the world have inspired an outpour of creative response. As the effects of climate change increasingly manifest, environmental! art is being politically and pedagogically mobilised for ameliorative strategies. The rubric that instrumentalist, techno-scientific approaches to environmental stress (and attendant social distress) cannot solely provide solutions to this challenge has found increasing acceptance. The concern of this paper, however, is the limited understanding of public art's capacity that is perpetuated bv certain trends in environmental art in which the work is charged with communicative responsibility,. Connected to the representational and instructive traditions of public art, this tendency is further informed by the influence of the 'information-deficit model' in environmental conmunication research: a concept that asserts a straightforward connection between information provision, indiyidual awareness and collective action on a concern. The idea that public art can function as a conduit for knowledge,.which in turn will inspire new moral positions and behaviours, absents the art work from the process of knowledge-making and the production of conditons that enable new practice. Arguing for a revised approach to the environmental possibilities of public art, this paper will propose that in thinking aboutl environmental transformation as essentially unrepresentable, a dfferent mode of public engagement with the issue is enabled.

New way of seeing things : Ernst Troeltsch and the theological agenda

The aim of this thesis, as set out in the Introduction, is to assess the (seminal) significance of Troeltsch as one who set the agenda for twentieth century theology, particularly modern sociopolitical theology, and whose thought still has a special relevance. The first main chapter deals with the implications of the philosophy of history for theology. The Protestant theological orthodoxy of Troeltsch's time was essential ahistorical: he thought this to be untenable. Theology had to come to terms with the historical method, which was ‘a leaven which transforms everything, and finally bursts all previous forms of theological method.’ This chapter discusses Troeltsch's work concerning the principles, the cultural matrix, and the philosophy of history. The second main chapter examines another main concern of Troeltsch, namely, the status of Christianity vis-a-vis other religions. The background to this was the increasing awareness of the existence of other religions and the question of relativity and universality which this posed. Troeltschfs major response was Die Absolutheit des Christentums in which the ideas of essence, Europeanism, and absolutism were discussed, The third, and longest, chapter looks at the impact of social theory on theology. Sociology gave Troeltsch ‘a new way of seeing things’, and this new perspective is to be seen pre-eminently in The Social Teaching of the Christian Churches. Discussion of this centres on the three main concepts that Troeltsch delineated, compromise, natural law, and church/sect typology.

A comparison of the ICI Pillbox and the Random Tumble Methods is assessing pilling and appearance change of worsted spun cashmere and cashmere-wool blend knitwear

This study evaluated the differences between two international test methods on the assessment of pilling and appearance change of worsted spun cashmere and superfine wool knitwear and their blends. Differences between the standard ICI Pill Box Method and the Random Tumble Method were found in both the significance and magnitude of resistance to pilling and appearance change and the amount of fabric mass loss of worsted spun cashmere and cashmere superfine wool blend knit fabrics. The ICI Pill Box Method differentiated to a greater extent the effects of wool type and blend ratio of cashmere and wool compared with the Random Tumble Method. Generally the addition of cashmere or low crimp superfine wool resulted in fabrics being more resistance to pilling and appearance change compared with fabrics made from high crimp superfine wool. This was associated with increased fabric mass loss when assessed by the ICI Pill Box Method but not with the Random Tumble Method. KEYWORDS: Cashmere, crimp, wool, pilling, appearance change, knitwear

De(con)struction of feminist solidarity and the question of environmental education reform

This thesis critically examines the implications of normative models of science, gender and feminism for environmental education. It examines issues relating to unequal power relations between the masculine and the feminine ways of knowing, the power relations between women - in particular between feminist educators. Pivotal to the analysis is an exploration of self empowerment and the identification of the author's own subjectivity.
