Eating Behaviors | Year: 2013

Objectives: Western culture has great influences on body dissatisfaction and related eating behaviors in adolescents. This study aimed to assess the sociocultural influences on eating attitudes and motivations among Hong Kong Chinese adolescents. Methods: In 2007, 909 adolescents (mean age=14.7. years, 55.3% boys) completed a survey with Stunkard's Figure Rating Scale (FRS), Motivation for Eating Scale (MFES), Eating Attitudes Test (EAT), Revised Restraint Scale (RRS), and Sociocultural Attitudes Towards Appearance Scale (SATAQ). In addition, their body mass index (BMI) was objectively measured. Results: Our results indicated that Hong Kong adolescents, particularly girls exhibited a remarked level of body dissatisfaction, external, emotional, restrained and disordered eating behaviors. Hierarchical regression analyses indicated that age, sex and BMI were the most common contributing factors to individual eating styles. SATAQ significantly accounted for an additional variance of body dissatisfaction (2%), physical eating (2%), external eating (1%), emotional eating (3%), restrained eating (5%), and disordered eating (5%). Conclusions: In Hong Kong, the sociocultural influences on body image and eating disturbance were supported. © 2013 Elsevier Ltd.

The consequences of intraspecific variation in prey traits for plant-herbivore interactions were tested by measuring the susceptibility of 3 phenotypes from the red alga Gracilaria cornea against herbivores from the coast of Israel. The 3 algal phenotypes ('fine', 'green', 'wild') differed in morphology, as well as nutritional value (organic content). When presented with the 3 G. cornea phenotypes simultaneously, the amphipod Ampithoe ramondi and the crab Acanthonyx lunulatus consumed significantly more of the finely branched phenotype (63 and 80% of total consumption, respectively) than of either the green or wild phenotypes. When confined with only 1 of the 3 algal phenotypes, feeding patterns of the crab changed little, consuming significantly more of the finely branched phenotype. In contrast, the amphipod responded by increasing consumption proportionally on the phenotypes with the lowest organic content. Regression analysis showed that A. ramondi exhibited compensatory feeding and consumed significantly more of the green phenotype than of either of the other 2 under no-choice conditions, with algal ash-free dry mass explaining approximately 83% of the variance in feeding for this mesograzer. Data suggest that feeding by crabs responded to algal morphology more, while amphipods cued on both structure and nutrient content of the algal phenotypes. © Inter-Research 2013.

Recent observed feminization of aquatic animals has raised concerns about estrogenic compounds in water supplies and the potential for these chemicals to reach drinking water. Public perception frequently attributes this feminization to oral contraceptives (OCs) in wastewater and raises concerns that exposure to OCs in drinking water may contribute to the recent rise in human reproductive problems. This paper reviews the literature regarding various sources of estrogens, in surface, source and drinking water, with an emphasis on the active molecule that comes from OCs. It includes discussion of the various agricultural, industrial, and municipal sources and outlines the contributions of estrogenic chemicals to the estrogenicity of waterways and estimates that the risk of exposure to synthetic estrogens in drinking water on human health is negligible. This paper also provides recommendations for strategies to better understand all the potential sources of estrogenic compounds in the environment and possibilities to reduce the levels of estrogenic chemicals in the water supply. © 2010 American Chemical Society.

In order to use power splitter for communication and real world applications (e.g., telephony performances, antenna designs, wireless communications, digital communications, optical communications, CATV transmission systems, airborne systems), studying the nature and characteristics of the splitter is important. The purpose of this paper is to review and discuss various techniques aimed to develop the power splitters component and remove its interference. This paper further focuses on the review of future implementation techniques and performance comparison along with their applications. Some of the applications are illustrated at the end of the paper, and recommendation for further study is also outlined. This review serves as a comparative studies and reference beneficial for power splitter researchers and for future implementation of the technology. This review paper opens a corridor for researchers to perform future comparative studies between different architectures and models as a reference point for developing more powerful, flexible and efficient applications.

Mast seeding involves the episodic and synchronous production of large seed crops by perennial plants. The predator satiation hypothesis proposes that mast seeding maximizes seed escape because seed predators consume a decreasing proportion of available seeds with increasing seed production. However, the seed escape benefits of masting depend not only on whether predators are satiated at high levels of seed production, but also on the shape of their functional response (type II vs. type III), and the actual proportion of available seeds that they consume at different levels of seed production. North American red squirrels (Tamiasciurus hudsonicus) are the primary vertebrate predator of white spruce (Picea glauca) mast seed crops in many boreal regions because they hoard unopened cones in underground locations, preempting the normal sequence of cone opening, seed dispersal, and seed germination. We document the functional response of cone-hoarding by red squirrels across three non-mast years and one mast year by estimating the number of cones present in the territories of individual red squirrels and the proportion of these cones that they hoarded each autumn. Even though red squirrels are not constrained by the ingestive and on-body (fat reserves) energy reserve limitations experienced by animals that consume seeds directly, most squirrels hoarded <10% of the cones present on their territories under mast conditions. Cone availability during non-mast years also reached levels that satiated the hoarding activity of red squirrels; however, this occurred only on the highest-quality territories. Squirrels switched to mushroom-hoarding when cone production was low and mushrooms were abundant. This resulted in type III functional response whereby the proportional harvest of cones was highest at levels of cone availability that were intermediate within non-mast years. Overall, more cones escaped squirrel cone-hoarding during a mast event than when cone production was low in non-mast years, which supports the predator satiation hypothesis. However, the highly variable seed escape in non-mast years may help to explain why all spruce cone production is not concentrated into fewer, larger, mast years. © 2010 by the Ecological Society of America.

We study global and local Q-measures, as well as betweenness centrality, as indicators of international collaboration in research. After a brief review of their definitions, we introduce the concepts of external and internal inter-group geodesics. These concepts are applied to a collaboration network of 1129 researchers from different countries, which is based on publications in bibliometrics, informetrics, webometrics, and scientometrics (BIWS in short) from the period 1990-2009. It is thus illustrated how international collaboration (among authors from different countries) in BIWS is carried out. Our results suggest that average scores for local Q-measures are typically higher, indicating a relatively low degree of international collaboration in BIWS. The dominating form of international collaboration is bilateral, whereas multilateral collaboration is relatively rare in the field of BIWS. We also identify and visualize the most important global and local actors. Dividing the entire period in four 5-year periods, it is found that most international collaboration in the field has happened in the last time slice (2005-2009). A comparison of the different time slices reveals the non-linear growth of the indicators studied and the international expansion of the field. © 2010 Akadémiai Kiadó, Budapest, Hungary.

As part of a research program to analyse research in Bangladesh we provide a comparison between research indicators related to India, Bangladesh, Pakistan and Sri Lanka. In this investigation we make use of Web of Science (WoS) data as well as Scopus data (using the SCImago website). Special attention is given to collaboration data and to the evolution of country h-indices. A comparison based on relative quality indicators shows that Sri Lanka is the best performer among these four countries. Such a result agrees with the ranking of these countries according to the United Nations' Human Development Index (HDI). © 2010 Akadémiai Kiadó, Budapest, Hungary.

This study presents the life cycle energy consumption, emissions, and environmental impacts of flat plate and evacuated tube domestic solar hot water system manufactured and used in Thailand. The results presented in this article show that the life cycle energy consumption for the flat plate system is 5% lower than that of evacuated tube system. The application of flat plate system is useful over evacuated tube system for 8 out of 12 emissions are examined. The global warming potential is 3% lower for the flat plate system than that of evacuated tube system. The average reduction of energy consumption and environmental impact by reusing materials are 65 and 50%, respectively for the flat plate and evacuated tube system. A comparative study with other systems available in the literatures based on few performance indicators shows that the energetic and environmental performance of domestic solar hot water system in Thailand is quite attractive. This article is useful to enhance the local production in line with energy and environmental sustainability in home and Asian neighboring countries. © 2015 American Institute of Chemical Engineers Environ Prog.

This poster focuses on the national level efforts taken in Bangladesh (one of the most climate-vulnerable countries) to face the immediate as well as long term challenges of climate change through green ICT based applications and infrastructure. "Digital Bangladesh" is a vision supported by the Government of Bangladesh (GoB) to integrate the ICT based interventions at every level of life [1]. It envisions the micro-level social inclusion of the base of the pyramid population (BoP) in the mainstream economic activities through ensuring access to information, cost-effective connectivity and efficient e-governance. As climate change is severely negating many achievement made by this developing country, efforts are in place to implement strategies towards developing "Green" ICT based nationwide infrastructure and services all over Bangladesh. This poster looks into the challenges towards fulfilling such objective. It also focuses on the strategic priorities and identifies future opportunities for making a nation's collective effort for a "green" future sustainable. The original research is a part of the ongoing process to monitor and evaluate this national level initiative. Copyright © 2011 ACM.

One of the defining characteristics of individuals with autism spectrum disorder (ASD) is difficulty with social interaction and communication with others, or interpersonal interaction. Accordingly, the majority of research efforts to date have focused on understanding the brain mechanisms underlying the deficits in social cognition and language associated with ASD. However, recent empirical and theoretical work has begun to reveal increasing evidence for altered self-representation, or intrapersonal cognition in ASD. Here we review recent studies of the self in ASD, focusing on paradigms examining 'physical' aspects of the self, including self-recognition, agency and perspective taking, and 'psychological' aspects of the self, including self-knowledge and autobiographical memory. A review of the existing literature suggests that psychological, but not physical, aspects of self-representation are altered in ASD. One key brain region that has emerged as a potential locus of self-related deficits in ASD is the medial prefrontal cortex, part of a larger 'default mode network'. Collectively, the findings from these studies provide a more comprehensive framework for understanding the complex social, cognitive, and affective symptomatology of ASD. © 2011 Psychology Press.
