Youth publications, generation Y and hopes for the future of newspapers

If readership projections are correct, newspapers in the United States will become niche players by 2010. That is, in about half a decade fewer than half of American adults will read a daily newspaper. This will produce major problems in attracting advertising, the lifeblood of the newspaper business. The biggest decline in readership has occurred among Generation Y - people born between 1977 and 1995. They do not read newspapers to the extent their parents did. They get their news elsewhere, mainly online. As part of a process to attract readers, many of America's major publishers launched a series of youth-focused newspapers in the 18 months to March 2004. The aim was to try to get the elusive 18-24-year-old demographic into the habit of daily reading, hoping that over time they would migrate to more traditional outlets. This paper explores the background to these youth-focused publications, describes the main players and issues involved, and provides a case study of a youth-focused pioneer, the Tribune Company s Red Eye, which is published in Chicago.

Brain neuropeptide Y and CCK and peripheral adipokine receptors : temporal response in obesity induced by palatable diet

Objective:
Palatable food disrupts normal appetite regulation, which may contribute to the etiology of obesity. Neuropeptide Y (NPY) and cholecystokinin play critical roles in the regulation of food intake and energy homeostasis, while adiponectin and carnitine palmitoyltransferase (CPT) are important for insulin sensitivity and fatty acid oxidation. This study examined the impact of short- and long-term consumption of palatable high-fat diet (HFD) on these critical metabolic regulators.

Methods:
Male C57BL/6 mice were exposed to laboratory chow (12% fat), or cafeteria-style palatable HFD (32% fat) for 2 or 10 weeks. Body weight and food intake were monitored throughout. Plasma leptin, hypothalamic NPY and cholecystokinin, and mRNA expression of leptin, adiponectin, their receptors and CPT-1, in fat and muscles were measured.

Results:
Caloric intake of the palatable HFD group was 2–3 times greater than control, resulting in a 37% higher body weight. Fat mass was already increased at 2 weeks; plasma leptin concentrations were 2.4 and 9 times higher than control at 2 and 10 weeks, respectively. Plasma adiponectin was increased at 10 weeks. Muscle adiponectin receptor 1 was increased at 2 weeks, while CPT-1 mRNA was markedly upregulated by HFD at both time points. Hypothalamic NPY and cholecystokinin content were significantly decreased at 10 weeks.

Conclusion:
Palatable HFD induced hyperphagia, fat accumulation, increased adiponectin, leptin and muscle fatty acid oxidation, and reduced hypothalamic NPY and cholecystokinin. Our data suggest that the adaptive changes in hypothalamic NPY and muscle fatty acid oxidation are insufficient to reverse the progress of obesity and metabolic consequences induced by a palatable HFD.

Gen Y and their 'backpacks of hidden treasures'

This paper reports on part of a teacher/researcher’s PhD action research study conducted in an Australian public high school, investigating the use of online social networking as a classroom learning environment where students were encouraged to find and use their hidden treasures. It examines student reactions and online activity whilst they are interacting with a range of Web 2.0 and social media tools. The study may inform the rising generation of higher education learners and their course developers and explores the move from passive to active learning through Gen Y’s engagement with online social media. It looks at a range of innovative practices that were made possible through using a Ning online social network as a classroom environment whilst encouraging Gen Y to take more responsibility for learning. It also looks at the pedagogical implications that come with the use of social media as they challenge traditional models of ‘instructional order’. This study primarily adopts a social constructivist approach to teaching with the focus being on learning, rather than teaching. The study found that having such a flexible curriculum environment encouraged Gen Y to share their ‘hidden treasures’ and, hence, informal classroom learning became more visible and more readily documented. Gen Y students appreciated the opportunities to publish and to gain feedback from more than their teacher alone. Students, in some cases, could be seen to be engaged in their own cycle of learning where they valued the opinion of their peers which, in turn, helped them to improve their work.

The diving behaviour of green turtles undertaking oceanic migration to and from Ascension Island: dive durations, dive profiles and depth distribution

Satellite telemetry was used to record the submergence duration of green turtles (Chelonia mydas) as they migrated from Ascension Island to Brazil (N=12 individuals) while time/depth recorders (TDRs) were used to examine the depth distribution and dive profiles of individuals returning to Ascension Island to nest after experimental displacement (N=5 individuals). Satellite telemetry revealed that most submergences were short (<5 min) but that some submergences were longer (>20 min), particularly at night. TDRs revealed that much of the time was spent conducting short (2–4 min), shallow (approximately 0.9–1.5 m) dives, consistent with predictions for optimisation of near-surface travelling, while long (typically 20–30 min), deep (typically 10–20 m) dives had a distinctive profile found in other marine reptiles. These results suggest that green turtles crossing the Atlantic do not behave invariantly, but instead alternate between periods of travelling just beneath the surface and diving deeper. These deep dives may have evolved to reduce silhouetting against the surface, which would make turtles more susceptible to visual predators such as large sharks.

Social value measurement and nonprofit organizations: preliminary views of nonprofit and foundation managers

This paper examines how managers of nonprofit organizations and foundations view the measurement of the social value of these organizations. In exploratory interviews, we found that the managers generally agree that objective measures are desired where and when possible, but recognise the difficulties in developing an assessment that enables comparisons across the nonprofit sector. These difficulties, as well as the implications for developing assessments of social value for nonprofit organizations, are discussed

Adaptation and self-undermining postmodern views of the world

This paper examines the artistic construction of fictional and non-fictional characters and worlds and shows how adaptation changes non-fiction into fiction. This is illustrated with two films, Adaptation (Spike Jonze, 2002) and American Splendor (Shari Springer Berman and Robert Pulcini, 2003). These films are examples of self-reflexive intertextuality, in which the film chronicles the process of its own making and contains multiple portrayals of the characters and story world that inform reading/viewing. Postmodern irony is implicated in this process, which is shown to be self-undermining. The self-loathing of the characters Laroche, Orlean, Kaufman and Pekar is related to the self-loathing arising from Schopenhauer's view of the world, in which the will to life must be renounced to achieve equanimity. The dialogue that results from reading/viewing informed by differences and switching undermines the interpretation of critics that the non-fiction works and film adaptations reflect the postmodern world view, in which a person's self is created by the rush of phenomena, where persons do not change and nothing is resolved.

Fast road detection and tracking in aerial videos

 We propose a fast approach for detecting and tracking a specific road in aerial videos. It combines adaptive Gaussian Mixture Models (GMMs) to describe road colour distributions, and homography based tracking to track road geometries, where an efficient technique is developed to estimate homography transformations between two frames. Experiments are conducted on videos captured by our unmanned aerial vehicles. All the results demonstrate the effectiveness of our proposed method. We test 1755 frames from 5 videos. Our approach can achieve 0.032 seconds per frame and 2.64% segmentation error for images with 908 × 513 resolutions, on average.

Congestion and optimal immigration policy

This paper presents a model to explain the stylized fact that many countries have a low ratio of migrants in their population while some countries have a high ratio of migrants. Immigration improves the income of the domestic residents, but migrants also increase the congestion of public services. If migrants are unskilled and therefore pay low taxes, and the government does not limit access to these services, then the welfare of the domestic residents decreases with the number of migrants. Visa auctions can lower the cost of immigration control and substitute legal migrants for illegal migrants. If the government decides to limit the access of migrants to public services, immigration control becomes unnecessary and the optimal number of migrants can be very large.

Urban heat island and wind flow characteristics of a tropical city

 Urban Heat Island (UHI) has become a growing concern to the quality of densely built urban environments, particularly in tropical cities. Wind speed has widely been reported to have decreased the intensity of heat island effect in urban areas. The cooling effect of the wind helps to mitigate the adverse effects of heat island on the micro climate and human thermal comfort. This paper investigates the existence of heat island in Muar, one of the fast growing cities in southern part of Malaysia and its possible causes, and then examines the effects of different urban geometry on the wind flow. The results of this study indicate that the chaotic development in Muar has caused reduced ventilation in urban canyons. The heat island intensity in the city center was recorded as 4. °C during the day and 3.2. °C during the night. Investigation of various urban geometry modifications showed that step up configuration was the most effective geometry as it can distribute the wind evenly allowing the wind to reach even the leeward side of each building. © 2014 Elsevier Ltd.

Re-framing values for a World Heritage future: what type of icon will K'gari-Fraser Island become?

K’gari-Fraser Island, the world's largest barrier sand island, is at the crossroads of World Heritage status, due to destructive environmental use in concert with climate change. Will K’gari-Fraser Island exemplify innovative, adaptive management or become just another degraded recreational facility? We synthesize the likely impact of human pressures and predicted consequences on the values of this island. World-renown natural beauty and ongoing biological and geological processes in coastal, wetland, heathland and rainforest environments, all contribute to its World Heritage status. The impact of hundreds of thousands of annual visitors is increasing on the island's biodiversity, cultural connections, ecological functions and environmental values. Maintaining World Heritage values will necessitate the re-framing of values to integrate socioeconomic factors in management and reduce extractive forms of tourism. Environmentally sound, systematic conservation planning that achieves social equity is urgently needed to rectify historical mistakes and update current management practices. Characterizing and sustaining biological refugia will be important to retain biodiversity in areas that are less visited. The development of a coherent approach to interpretation concerning history, access and values is required to encourage a more sympathetic use of this World Heritage environment. Alternatively, ongoing attrition of the islands values by increased levels of destructive use is inevitable.

The passage of authority: imagining the political transformation of Australia’s Christmas Island, from sovereignty to governance

In 2012, Australia’s Christmas Island is best known as an island of immigration detention, a key component of Australia’s growing offshore border security apparatus, where interdicted boat arrivals seeking asylum are detained and processed. This article offers one account of how the Island came to be what it is, by providing two snapshots of the operable set of power relations on Christmas Island, then and now: ‘Island in the Sun’, and ‘Tropics of Governance’. Side by side, their stark contrast reveals the passage of authority through time and place, from the embodied, unified voice of the sovereignty of the British Empire to the palliative communication and bureaucratic sincerity that characterise governance. By disclosing shifting patterns of emergence and decay and showing border security’s intimate relation to governance, this article seeks to offer a deepened understanding of the current detention situation in its immanence. What can now be seen as Christmas Island’s past follies also reveals the restless work of successive political imaginations, the shifting ways and means by which an island can be translated into a solution to a political problem, and how successive solutions tend toward wreck and ruin.
