Fluorescent Proteins And Chromoproteins In Phylum: Cnidaria, Mario Lewis

The Plymouth Student Scientist

Green fluorescent protein was first discovered in Aequorea victoria. Its significance in a continually expanding range of scientific applications led to the discovery of an abundance of homologous fluorescent proteins and non-fluorescent chromoproteins in a variety of species in the phylum Cnidaria. The document reviews the various proposed hypotheses on the biological functions and biochemistry of fluorescent proteins and chromoproteins, wherein a full resolution remains elusive and is the subject of on-going debate. Mutagenesis has provided novel variants and insights into the relationship between the spectral characteristics and chromophore structures of fluorescent proteins that encompass the visible spectrum. Fluorescent proteins …

Effects Of Algal Toxicity On The Clearance Rate Of The Blue Mussel (Mytilus Edulis), Samantha Bowgen

The Plymouth Student Scientist

The purpose of this study was to investigate the effect of toxic strains of Karlodinium veneficum on the clearance rate of Mytilus edulis. Suspensions of the toxic strain and the non-toxic strain of K. veneficum, mixed with an alternative non-toxic species, Prorocentrum micans, were made and performed as parallel experiments in order to compare their effects on clearance rate. Clearance rate was measured by taking samples from suspensions every five minutes up to 30 minutes, and counting the algal cells found within each sample using a Sedgewick rafter slide. No significant difference was found between the two experiments (F (9.322, …

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 …

An Evaluation Of Whether Artificial Refuge Traps Or Baited Traps Are The Most Effective Method For Trapping White-Clawed Crayfish (Austropotamobius Pallipes), Kathryn Walter

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 …

The Use Of Errorless Learning In The Rehabilitation Of Action Disorganisation Syndrome: A Case Study, Blaize Dymond

The Plymouth Student Scientist

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 …

Mood Affective Outcomes From Alternate Learning Strategies: Cognitive Flexibility And Dyslexic Education, Dylan Williams

The Plymouth Student Scientist

It is theorized that persons with dyslexia and associated conditions may be vulnerable to negative wellbeing, alongside academic deficiency, which has been focused on more widely. This study aims to investigate this theory in teenagers, and to draw relationships with teaching methods. Participants were interviewed, and completed the PANAS (Positive and Negative Affect) scale for children, the Matson Evaluation of Social Skills for Youngsters, and the Educational Environment Survey (an assessment of perceptions on education and ability). Participants with dyslexia and associated conditions showed reduced wellbeing compared to controls, and identified distinct experiential differences of education. This study was successful …

Singing Songs In A Strange Land: The Plight Of Haitian Children In The Space Of International Adoption., Glenys P. Spence

The Scholar: St. Mary's Law Review on Race and Social Justice

The best interests of children are not served by severing the familial bonds contemplated by international adoption law. Nonetheless, because of the high costs of the international adoption process, efforts to adopt their Haitian orphan relatives are ignored. In attempts to guarantee the “best interests of the child” are met, the United Nations Convention on the Rights of the Child (CRC) and the Hague Convention on the Protection of Children Co-Operative Respect of Intercountry Adoptions (Adoption Convention) were created as the two governing bodies of international adoption law. Global South countries, including Haiti, however, have not ratified the Adoption Convention. …

The Thirteenth Amendment Won't Help Free Willy., Sheri Flannery

The Scholar: St. Mary's Law Review on Race and Social Justice

Orcas are not afforded any relief under the Thirteenth Amendment. Animal rights advocates, namely People for the Ethical Treatment of Animals (PETA), alleged animals have the right to be free from slavery and involuntary servitude as guaranteed by the Thirteenth Amendment. Although the Thirteenth Amendment has been extended beyond African slavery, its protections have never been granted to anything other than human beings. The United States Supreme Court’s examination and interpretation of the Thirteenth Amendment concluded that animals are not afforded such protections under this amendment. The Court reasoned that the Thirteenth Amendment only applied to humans and not animals. …

Theses and Dissertations - UTB/UTPA

This single subject qualitative case study investigated the impact interest had on reading motivation for a struggling Mexican American adolescent reader from the Rio Grande Valley region of South Texas. Moreover, the study’s findings found several factors that impacted the subject’s motivation to read; factors which impacted the subject’s reading motivation were associated with his home and school life environment, his attitudes towards literacy activities, and the teaching and learning engagements which occurred throughout the study.

Aqui Es: The Rhetoric Of Identification In An Act Of Local Branding, Bonnie M. Garcia

Theses and Dissertations - UTB/UTPA

Brands are a large part of our cultural discourse. In the Rio Grande Valley a group of network-marketing sponsored entrepreneurs has tapped into branding as a rhetorical resource. I use Burke’s concept of consubstantiation to analyze the rhetorical motives represented both in the use of branding in general and in the “Aqui Es” sign utilized by local nutrition clubs. Burke’s concept of consubstantiation allows me to contextualize the production of the sign and open avenues to explore the relationships behind the sign’s use. I then utilize Lacanian psychoanalysis to explain the psychological motives behind the sign’s use and production. I …

Theses and Dissertations - UTB/UTPA

Many institutions of higher education face a common challenge - retaining students in a time when higher education is of most importance as students must be prepared to compete in today's fast growing global market. Students are dropping out of college at an alarming rate due to the lack of academic readiness. The main area of academic deficiency is in the area of mathematics (National Center for Education Statistics, 2006). The purposes of this qualitative multiple case study were to explore the effectiveness of remediation courses in mathematics and identify the factors that influence success or failure of Hispanic students …

Evidence Of Olfactory And Visual Learning In The Asian Citrus Psyllid, Diaphorina Citri Kuwayama (Hemiptera: Psyllidae), Dara G. Stockton

Theses and Dissertations - UTB/UTPA

Investigation of the mechanisms underlying learning and memory can be achieved through research on neurobiologically simplified invertebrate species. As such, insects have been used for decades as ideal models of olfactory learning. The current study aimed to investigate the mechanisms of chemosensory attraction in an invasive insect, Diaphorina citri, the Asian citrus psyllid (ACP), through manipulation of olfactory stimuli. After classical conditioning to a non-innate cue (vanilla extract), psyllids displayed enhanced feeding behavior. There was, however, an inverse relationship between olfactory “noise” and feeding behavior. Preliminary data suggests ACP may also be visual learners, as evidenced by trials attempting to …

A Comparison Of Display Techniques For Large Graphs, Ana Rocio Pena

Theses and Dissertations - UTB/UTPA

Visualizing information focuses on the display of data in order to provide the user a representation that provides understanding of the data. Information visualization systems typically couple interaction mechanisms for providing overviews of the data with more detailed information through a zooming interface. This thesis compares three different techniques for displaying graphs provided by the prefuse visualization system: force-directed node positioning, radial node positioning, and a tree view of graphs. Using a large, real world data set from the South Texas College’s Distance Education department, the three visualization techniques are compared for a set of tasks that users routinely need …

Impulsivity And Suicidal Ideation Or Attempt In Younger And Older Adults, Elizabeth C. Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rates of suicidal behaviors vary over the lifespan, but little research has focused on developmental aspects of suicidal behaviors and associated risk factors. Previous studies suggest that young people who attempt or die by suicide are likely to be generally impulsive. 108 community-dwelling older adults age 60 and older and 498 undergraduate students ages 18-30 completed the Center for Epidemiological Studies -- Depression Scale, the Barratt Impulsivity Scale, and the Suicidal Behaviors Scale -- Revised. The hypothesis was that the relation between impulsivity and suicidal ideation or attempt, in the context of depressive symptoms, would be stronger in younger adults …

Graduate Theses, Dissertations, and Problem Reports (ETD)

The study compared the effects of Direct Instruction (DI) with DI+Environmental Design Instruction (EDI) on the refinement of both simple and difficult gymnastics skills refinement. Four boys aged six to eight with two years of gymnastics training experiences participated in the simple skill experiment (running tuck jump on the springboard). Four boys aged 11 to 13 with more than three years of gymnastics training experiences participated in the difficult skill experiment (mushroom circles). Three dependent variables were measured in the experiment of running tuck jump and they were: (1) the participant's hip angle while they jumped at the highest point, …

The Effects Of Altering Response Effort During Data Collection On Observer Accuracy: Data Collection Procedures On Hand Hygeine Compliance, Krista Hinz

Masters Theses

When dealing with human observers and error, tight control in data collection and methodology is essential for accurate representation of compliance. Although observational studies are popular, little has been done to study the integrity of human observers and the data collection process. Incomplete analysis of data collection integrity threatens functional findings, leading to problematic interpretation and decreased replication. The purpose of the current study was to assess whether manipulating the response effort associated with data collection has an effect on the accuracy of data collection. Participants of the study were undergraduate psychology students at a Midwestern university who were enrolled …

The Effect Of Innovative Technology On Seatbelt Use, Bryan W. Hilton

Masters Theses

A previous pilot study documented that providing sustained haptic feedback to the gas pedal when a driver exceeded 25mph with his seatbelt unbuckled and removing the feedback contingent on seatbelt use increased seatbelt use in 7 commercial drivers. This study replicated this effect with 20 young drivers who did not consistently wear their seatbelt.

In the current study unbuckled drivers received increased accelerator pedal resistance when they exceeded 20 mph. A non-concurrent multiple baseline design was employed for this study. The dependent variable was percentage of trips driven without seatbelt use. The independent variable was an increase accelerator pedal resistance …

Dating Violence Policy: Making The Grade, Richard Hoefer, Beverly Black, Mashooq Salehin

The Journal of Sociology & Social Welfare

Dating violence rates affect an unacceptably high percentage of youth. This paper tests a model to understand the considerable variation in state dating violence policy comprehensiveness. Independent variables in the model are state political culture, partisan control of political institutions, prevalence of dating violence, and median household income. Bivariate results show partial support for preliminary hypotheses. Regression analysis indicates that strength of Democratic Party control of governmental institutions is the only variable in the model that achieved statistical significance. Implications and recommendations for future research are provided.

Explicating The Social Mechanisms Linking Alcohol Use Behaviors And Ecology To Child Maltreatment, Bridget Freisthler, Megan R. Holmes

The Journal of Sociology & Social Welfare

This paper begins to describe and explicate the specific mechanisms by which alcohol use and the alcohol use environment contribute to specific types of child maltreatment. These mechanisms relating alcohol outlet densities to child maltreatment described here include effects on social disorganization, parent's drinking behaviors, and parental supervision. By investigating potential mechanisms, new information could be obtained on the importance and role of alcohol and its availability in the etiology of child maltreatment. This knowledge can be used to further tailor interventions to those conditions most likely to prevent and reduce maltreatment.

Private Pension Protections Since Erisa: The Expanded Role Of The Individual, Karen A. Zurlo

The Journal of Sociology & Social Welfare

Designed to provide security and equity to defined benefit (DB) pension plans, the Employee Retirement Income Security Act (ERISA) became law in 1974. Since that time, the economy has shifted to a more globalized, non-unionized, service-based environment, where defined contribution (DC) plans replaced DB plans as the dominant type of private pension plan. Today workers and retirees bear the burden of managing their pension plans and the associated risks. To protect Americans against the financial risks they face in retirement and ensure greater economic security in old age, targeted financial education, research, and fundamental pension policy reform are required.
