Sociosexuality, Mate Preferences, And Sex Steroid Hormone Levels Among Breastfeeding Women In Manila, Michelle Escasa

UNLV Theses, Dissertations, Professional Papers, and Capstones

This project investigates the influence of lactation on female sociosexuality and mate preferences in urban Manila, a population with long-term breastfeeding, low contraceptive use, and quick return to ovulatory cycling. Physiological and evolutionary considerations suggest that lactating women face important life history allocation trade-offs between mating and parenting effort that may be manifest in their sociosexual behavior and mate preferences. Breastfeeding (n=155) and control (n=105) women were recruited to provide a saliva sample (for testosterone and estradiol analyses), complete a questionnaire, and complete a face and voice preference task to determine preferences for masculinity. Breastfeeding women reported differences in commitment …

Timeliness Of Electronic And Traditional Laboratory Reporting In Southern Nevada, 1999-2012, Jennifer Anne Lucas

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study compares the timeliness of Electronic Laboratory Reporting (ELR) with traditional reporting. ELR has been implemented in parts of the United States, and is perceived to be faster than traditional reporting. Faster reporting leads to faster public health response to prevent outbreaks, and to reduce the burden of infectious disease in communities. Nevada State law requires that diseases be reported within certain time frames. Timeliness of laboratory reporting at the Southern Nevada Health District (SNHD) from 1999-2012 was assessed by analyzing cases of four common diseases in this retrospective secondary analysis of extant data.

The difference in timeliness regarding …

On The Importance Of Modeling Stent Procedure For Predicting Arterial Mechanics, Shijia Zhao, Linxia Gu, Stacey R. Froemming

Department of Mechanical and Materials Engineering: Faculty Publications

The stent-artery interactions have been increasingly studied using the finite element method for better understanding of the biomechanical environment changes on the artery and its implications. However, the deployment of balloon-expandable stents was generally simplified without considering the balloon-stent interactions, the initial crimping process of the stent, its overexpansion routinely used in the clinical practice, or its recoil process. In this work, the stenting procedure was mimicked by incorporating all the above-mentioned simplifications. The impact of various simplifications on the stent-induced arterial stresses was systematically investigated. The plastic strain history of stent and its resulted geometrical variations, as well as …

Permaculture And Public Health: Mitigation Of The Lifestyle Risk Factors For Type 2 Diabetes Through The Establishment Of Permaculture Edible Forest Gardens, Brett Christopher Lehner

Honors Scholar Theses

Over the past thirty years, the incidence of type 2 diabetes and obesity has greatly increased in the United States. This paper compares the living environment of hunter-gathers to that of modern humans, in diet and activity levels, and discusses the recent increase of type 2 diabetes as a 'disease of civilization'. To address these changes in dietary composition and activity levels, an alternative agricultural model, permaculture edible forest gardening, is proposed. Permaculture edible forest gardening is an agricultural model which mimics natural ecosystem structure while consisting of entirely edible, perennial plant species. Permaculture edible forest gardens can potentially play …

METHODS: Eleven patients with hepatitis C and detectable viremia were enrolled. Four had Child-Pugh (CP) class A cirrhosis, 4 had Child-Pugh class B cirrhosis, and 3 were noncirrhotic. After a single oral dose of green tea extract 400 …

A Critical Analysis Of The Kyoto Protocol Using Monte Carlo Simulation And Magicc, Penny Lambert

The Plymouth Student Scientist

The United Nations Framework Convention on Climate Change adopted the Kyoto Protocol in December 1997. Emissions data from national registries were used to quantify the total anthropogenic emissions of signatory parties between 1990 and 2009, found to have been reduced by approximately 18 percent of base year levels. Using IPCC Special Report Emissions Scenarios (SRES) as a practicable baseline for non-mitigation, three distinct intervention scenarios were constructed from target and observed emissions reductions under the Protocol to investigate their climatic implications against unabated anthropogenic carbon by the end of the 21st century. MAGICC Version 5.3 was used to model forecast …

Effects Of A Gardening Task On Chocolate Craving, Sarah-Jane Baugh

The Plymouth Student Scientist

Two concepts, craving and nature, were brought together to investigate the effects of a gardening task on chocolate craving. Participants (n = 105) completed a chocolate craving induction before taking part in one of three, five minute tasks (gardening, plasticine, counting). Measures of craving, mood, arousal, attention and heart rate were recorded. The gardening task was found to have beneficial effects with participants experiencing significant changes in energetic arousal (p= .01) and feeling good (p< .01); however, no significant effects were found in the other measures.

The Effect Of Itgd Sensitivity And Contact On Attitudes Towards Burqas, Sophie Augarde

The Plymouth Student Scientist

The presented research investigates whether intergroup disgust sensitivity (affect-laden construct reflecting individual differences to experience revulsion towards outgroups) predicts greater prejudicial attitudes towards burqas. In addition to investigating the effect of ITGD sensitivity on prejudicial attitudes, types of contact (no contact, imagined contact and physical contact) between participants and an outgroup member were investigated to assess the efficacy of reducing prejudice towards women who wear burqas. ITGD sensitivity along with attitude towards burqas was measured over two sessions. Results indicated that there was no statistically significant effect of ITGD sensitivity or contact type on attitudes towards burqas. However, mean score …

The Plymouth Student Scientist

Britain’s only native crayfish species, the white-clawed crayfish Austropotamobius pallipes are threaten through rapid population declines caused by non-indigenous species, habitat degradation and pollution. This study focuses one of the last remaining small A. pallipes population in the Creedy Yeo River, Devon. This study aims to decipher whether the use of artificial refuge traps (ARTs) or baited traps are the most effective method of catching this species, to aid translocation efforts to conserve the remaining population under threat from the American signal crayfish Pacifastacus leniusculus. The capture rate of each type of trap was studied at four sites along the …

Location, Demographic, Lifestyle And Behavioural Influences On Household Participation In Bournemouth Borough Council's Kerbside Recycling Scheme, Stephanie Rooke

The Plymouth Student Scientist

Bournemouth Borough Council (BBC) is performing well in recycling and currently has a recycling rate of 63.9%, but there is still room for BBC to improve the efficiency of the existing ‘Big Bin’ dry kerbside recycling collection scheme and increase the recycling rate further. The aim of the study was to identify the socio-economic groups which participate the least, or contaminate the most, in BBC’s kerbside recycling scheme. A participation survey was carried out over three consecutive collection cycles for three recycling rounds ‘RW1, RW2 and RW5’ to measure how many times each individual household set out their recycling bin …

The Conservation Biology And Ecology Of The African Leopard Panthera Pardus Pardus, Ross Tyzack Pitman

The Plymouth Student Scientist

The African leopard Panthera pardus pardus is an apex predator, and a reliable indicator of a healthy ecosystem. Currently assessed as ‗near threatened‘ by the IUCN Red List of Threatened Species, leopards are exposed to a range of threats that include: habitat loss and/or degradation, depletion of natural prey, conflict with people, consumptive- and non-consumptive practices, and the illegal trade of leopard products. Leopards have disappeared from 37% of their historical range, and are continuing to decline. Leopards have been extirpated across many areas of Africa, especially where people are densely populated, which has left patchily distributed leopard populations throughout …

Spatial And Temporal Patterns Of Erosion Along The Holderness Coastline, North East Yorkshire, Uk, Verity Macfarlane

The Plymouth Student Scientist

There is an increasing problem of erosion in coastal environments, particularly in soft material cliffs which need to be protected; migration to these environments is increasing, up to 75% more of the total population is predicted to live in close proximity to the coast by 2020. The Holderness coast (located in North East Yorkshire, UK) is the fastest eroding coastline in Europe. It comprises of soft clay, glacial till deposits from the Devensian period (18-13Ka). Previous studies have calculated that many parameters such as till properties, cliff geomorphology, cliff topography, strength and reaction to varied water contents are varied throughout …

Biologging Science: Advances In Our Knowledge Of Seabirds And Their Behaviours, David Evans

The Plymouth Student Scientist

The use of miniature tags attached to free-living animals to record data is termed ‘biologging’. This procedure has been used to study seabirds since the 1970’s and our knowledge of their behaviour, physiology and migration has advanced through the decades, along with the potential for conservation of species. Technological advances in recent years have improved data resolution and storage, enabling a better understanding of seabirds and their environment

The Effects Of Logging And Fragmentation On Bird Diversity, Bethany Mccarthy

The Plymouth Student Scientist

Deforestation and forest degradation is occurring globally at an alarming rate. The annual net loss of forest cover has been reduced in the past decade through sustainable forest management and conservation measures. Despite this, the remaining forest is becoming increasingly degraded with the total area of primary forest declining. Avian diversity has been shown to decline in degraded and fragmented forests due to logging activities. In this review the impacts of logging on avian communities are assessed by comparing diversity between primary forest and degraded secondary forest, industrial plantations and forest fragment sizes. The major organisations and current initiatives that …

This case study investigates the use of errorless learning in the rehabilitation of action disorganisation syndrome (ADS). Case DL suffered 2 traumatic brain injuries to the frontal lobes (2002 and 2010) and presents with a clear case of ADS. DL displays high levels of disorganisation when engaging in sequential tasks. Errorless learning was used in an attempt to rehabilitate abilities in two everyday routine sequential actions; making a cup of tea and making toast with butter and jam. Errorless learning involves the deliberate prevention of errors using both verbal and physical prompts. The intervention resulted in a significant decline in …

The Positive Effects Of Aquarium Visits On Children's Behaviour: A Behavioural Observation, Hazel Cocker

The Plymouth Student Scientist

To date research has found a positive effect of blue spaces on adults’ wellbeing. However, it remains to be seen whether these findings are also true for children. The present study aims to address this gap in the literature. The researchers observed children’s behaviour at the National Marine Aquarium across two weeks, including one where the Big Draw event was taking place. In line with restorative theories of natural environments (Kaplan, 1995, Ulrich, 1983), the current research found the exhibit had a calming effect on behaviour and increased levels of happiness across both weeks. During the Big Draw week children …
