Can Self-Esteem Protect Against The Deleterious Consequences Of Self-Objectification For Mood And Body Satisfaction In Physically Active Female University Students?, Cecilie Thøgersen-Ntoumani, Nikos Ntoumanis, Jennifer Cumming, Kimberley J. Bartholomew, Gemma Pearce 2011 University of Birmingham

Can Self-Esteem Protect Against The Deleterious Consequences Of Self-Objectification For Mood And Body Satisfaction In Physically Active Female University Students?, Cecilie Thøgersen-Ntoumani, Nikos Ntoumanis, Jennifer Cumming, Kimberley J. Bartholomew, Gemma Pearce

Jennifer Cumming

Using objectification theory (Fredrickson & Roberts, 1997), this study tested the interaction between self-objectification, appearance evaluation, and self-esteem in predicting body satisfaction and mood states. Participants (N = 93) were physically active female university students. State self-objectification was manipulated by participants wearing tight revealing exercise attire (experimental condition) or baggy exercise clothes (control condition). Significant interactions emerged predicting depression, anger, fatness, and satisfaction with body shape and size. For participants in the self-objectification condition who had low (as opposed to high) appearance evaluation, low self-esteem was associated with high depression, anger, and fatness and low satisfaction with body shape and size. In ...


An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders 2011 Decision Processes Incorporated

An Income-Based Analysis Of Historical Us Energy Consumption, Harry D. Saunders

Harry D. Saunders

This paper introduces a new decomposition of energy consumption to reveal the effects of consumer income levels on energy use. It concludes that the great bulk of energy consumption in the US is embedded in goods and services purchased by consumers and that this component of energy demand is growing more rapidly than direct use of energy by households owing to the preferences of high-income consumers. Significantly, this embedded component of energy demand has historically experienced large rebound magnitudes. The analysis also concludes that energy consumption is driven by more than just income level, with the lowest-income consumers using more ...

Reactive Oxygen Species-Induced Impairment Of Endothelium-Dependent Relaxations In Rat Aortic Rings: Protection By Methanolic Extracts Of Phoebe Grandis, Dharmani Devi A/P Murugan

Dharmani Devi A/P Murugan

Generation of reactive oxygen species plays a pivotal role in the development of cardiovascular diseases. The present study describes the effects of the methanolic extract of Phoebe grandis (MPG) stem bark on reactive oxygen species-induced endothelial dysfunction in vitro. Endothelium-dependent (acetylcholine, ACh) and -independent relaxation (sodium nitroprusside, SNP) was investigated from isolated rat aorta of Sprague-Dawley (SD) in the presence of the beta-NADH (enzymatic superoxide inducer) and MPG extract. Superoxide anion production in aortic vessels was measured by lucigen chemiluminesence. Thirty minutes incubation of the rat aorta in vitro with beta-NADH increased superoxide radical production and significantly inhibited ACh-induced relaxations ...

La quinua real que crece en el Altiplano Sur de Bolivia, es uno de los alimentos más nutritivos del mundo. En las últimas décadas, la popularidad de la quinua en el mundo, ha aumentado mucho, provocando muchos cambios dentro de Bolivia. Uno de estos cambios es, la transformación del consumo interno de quinua en Bolivia. Por siglos el consumo de quinua fue muy bajo en la población general, mientras para los productores de quinua la quinua fue su principal alimento. Ahora, con la mayor consciencia de los valores nutritivos de la quinua, el consumo por la población general está aumentando ...


A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis 2011 SIT Study Abroad

A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis

Independent Study Project (ISP) Collection

The increased demand for marine products has fueled a worldwide overexpansion of the fishing industry. Furthermore, the shift of lower-income countries, like Madagascar, from subsistence to market-based cash economies has led to increased fishing pressures on marine resources. Recent commercialization of fisheries in Southwest Madagascar has caused an over-exploitation of octopus in the Toliara region. In an effort to create sustainable octopus fisheries, Blue Ventures, a UK-based NGO, created the world’s first community run Marine Protected Area (MPA) for octopus near Andavadoaka called Velondriake.

Here, the results of an Octopus cyanea habitat study performed near Beheloke, a fishing village ...

Adult Female Activity Time Budgets In Red-Bellied Lemurs (Eulemur Rubriventer) And Infant Survival: Ranomafana National Park, Frances Hardy

Independent Study Project (ISP) Collection

My research during the independent study period focuses on the relationship between activity time budgets of adult female red-bellied lemurs (Eulemur rubriventer) and infant survival. I conducted my research under the guidance of Centre ValBio in Ranomafana National Park. Red-bellied lemurs have a clear three month birth peak from Aug-Oct, but up to 30% of infants in a single year can be born outside of this birth peak, however, survival for out-of-season infants is strikingly low compared to in-season infants, 100% (n=4) of out-of-season infants died in one study conducted in 2009, whereas only 11% (n=18) of in-season ...

Dissecting The Workforce And Workplace For Clinical Endocrinology, And The Work Of Endocrinologists Early In Their Careers, Claude Desjardins, Mark A. Bach, Anne R. Cappola, Ellen W. Seely, Ronald G. Ehrenberg

Articles and Chapters

[Excerpt] No national mechanism is in place for an informed, penetrating, and systematic assessment of the physician workforce such as that achieved by the National Science Foundation (NSF) for the periodic evaluation of the nation’s scientists and engineers. Likewise, knowledge of the workforce for clinical research is enigmatic and fragmentary despite the serial recommendations of “blue-ribbon” panels to establish a protocol for the recurrent assessment of clinical investigators early in their careers. Failure to adopt a national system for producing timely, high-quality data on the professional activities of physicians limits the application of improvement tools for advancing clinical investigation ...

Companion Animals as Laboratory Research Subjects

Dogs are sometimes referred to as “man’s best friend” and with the increase in urbanization and lifestyle changes, dogs are seen by their owners as family members. Society expresses specific concerns about the experimental use of dogs, as they are sometimes perceived to have a special status for humans. This may appear somewhat conflicting with the idea that the intrinsic value of all animals is the same, and that also several other animal species are used in biomedical research and toxicology. This aspect and many others are discussed in an introductory chapter dealing with ethical considerations on the use ...

2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) inhibits antibody secretion and immunoglobulin heavy chain (IgH) expression. Our previous work has shown that a possible mechanism for inhibition of IgH expression could be inhibition of the 3’IgH regulatory region (3’IgHRR). The 3’IgHRR has four enhancer regions (hs3a; hs1,2; hs3b; hs4) which are purported to control IgH gene expression. Previously we demonstrated a sensitive inhibition by TCDD of LPS-induced 3’IgHRR activity which is correlated with an inhibition of LPS-induced hs1,2 enhancer activity; however, the hs4 enhancer showed TCDD-induced activation following the co-treatment of TCDD and LPS. Therefore, the ...


Low Levels Of Population Genetic Structure In Pinus Contorta (Pinaceae) Across A Geographic Mosaic Of Co-Evolution, T. L. Parchman, Craig Benkman, B. Jenkins, C. A. Buerkle 2011 University of Wyoming

Low Levels Of Population Genetic Structure In Pinus Contorta (Pinaceae) Across A Geographic Mosaic Of Co-Evolution, T. L. Parchman, Craig Benkman, B. Jenkins, C. A. Buerkle

Zoology Faculty Publications

Premise of the study : Population genetic analyses provide information on the population context in which evolutionary processes operate and are important for understanding the evolution of geographically variable traits. Earlier studies showed that cone structure of lodgepole pine in the Rocky Mountains diverged among populations because of geographic variation in co-evolutionary interactions involving mammalian and avian seed predators. Analyses of population genetic variation are needed to determine whether this divergence has arisen despite extensive gene flow and whether populations to the east and west of the Rocky Mountains have evolved convergent phenotypes independently. Methods : We investigated genetic structuring across 22 ...

Xenopus Laevis Transgenic Lines And Their Use In The Study Of Lymph Heart Musculature Development, Diana M. Filtz 2011 University of Richmond

Xenopus Laevis Transgenic Lines And Their Use In The Study Of Lymph Heart Musculature Development, Diana M. Filtz

Honors Theses

Lymph hearts are pulsatile organs present in lower vertebrates that propel lymph throughout the body and into the venous system, assisting in the maintenance of fluid homeostasis. In organisms such as frogs, several pairs of lymph hearts develop amidst the somites during the early tadpole stages. Due to the unique structure and function of lymph heart musculature—exhibiting characteristics of both skeletal and cardiac muscle—the origin of these cells remains highly controversial. Studies have found that in Xenopus, the engrailed gene is expressed explicitly in lymph heart muscle cells throughout development. Through designing a ...
