Effect Of Light Level On Feeding Behavior In A Lemur Species (Eulemur Rubriventer) With A Color Vision Polymorphism., Ainsley Lockhart

Independent Study Project (ISP) Collection

Understanding the visual capabilities and correlated behavior of prosimians provides vital information regarding the evolution of color vision. Feeding behavior in particular is often modified based on color vision status in various primate taxa. The present study examined feeding behavior under various light conditions in Eulemur rubriventer, a lemur species with a color vision polymorphism in which only females can have trichromatic vision. Behavioral observations were conducted for a single E. rubrventer group over a 13 day study period in April 2012. Results found no significant difference in rates of frugivory or exploitation of green vs. non-green food between male …

A Survey Of The Orchid Diversity (Orchidaceae) In Sainte Luce, Petriky, And Mandena (Southeast Madagascar), Anne Kathleen Johnson

Independent Study Project (ISP) Collection

This study examines the orchid diversity within three littoral forest sites in Southeast Madagascar. The sites, Sainte Luce, Petriky, and Mandena, are owned and managed by QIT Madagascar Minerals (QMM), an ilmenite mining organization jointly owned by Rio Tinto and the Malagasy government. The littoral forest is a habitat type dwindling in surface area; as such, it is a high conservation priority, and a portion of each of these three sites will be conserved by QMM. This study produces a list of orchid species present in the three zones, a list of host tree species on which epiphytic orchid species …

Effects Of A Cymothoid Ectoparasite On The Turning Behavior (Lateralization) Of The Bridled Monocle Bream Scolopsis Bilineata, Laura Strong

Independent Study Project (ISP) Collection

Lateralization, or behavioral asymmetry, is the tendency to favor one side of the body over the other, and exists in humans and animals including in mammals, birds, and fishes. It has been found to increase performance in certain behaviors such as escape from predators by lowering reation time. Lateralization has predominantly genetic bases, but can also be influenced by environmental factors. For example, lateralization has been observed to increase in populations of fish subject to high predation pressure as it decreases their response time to predatory attacks. Parasitism may also have important effects on lateralization. In particular, increased drag from …

Implications For Old-Field Restoration: Diversity And Abundance Of Arbuscular Mycorrhizal Fungi In Soils Of Restored York Gum (Eucalyptus Loxophleba Subsp. Loxophleba) Sites Vs. Remnants., Jessica Wong

Independent Study Project (ISP) Collection

Arbuscular mycorrhizal fungi (AMF) may be critical to the restoration of ecosystem function in old-fields. Whether the diversity of the plant community is promoted by the AMF community or is the driving force of AMF diversity is unknown. We investigated two questions in the context of old-field restoration in southwestern Australia: 1) Does restoration of the plant community achieve the restoration of AMF and 2) Is AMF species diversity and abundance influenced by the plant species composition? Our study sites were located in the Ridgefield Experiment in the University of Western Australia’s “Future Farm”. Soil samples were collected from beneath …

Evaluating Ceres Fair Food As An Urban Sustainable Food Initiative: A Comparison Of Retail Pricing, Wholesale Pricing And Food Miles For A Healthy Food Basket, Stella Chung

Independent Study Project (ISP) Collection

CERES Fair Food, an organic food delivery system in Melbourne, VIC was evaluated in terms of its transportation resource consumption, ability to enhance food security, and support of local organic farmers, which are key factors in sustainable food systems for urban areas.

Transportation resource consumption was analyzed by calculating the food miles for a selection of Fair Food’s products and comparing them to data on typical products consumed in Victoria. Most of Fair Food’s products had similar or lower food miles, particularly the fresh produce. But many assumptions had to be made in the calculations due to limited information. Food …

Curative Care As The Access Point To Rural Social Transformation A Case Study Of The Comprehensive Rural Health Project, Nancy Liu

Independent Study Project (ISP) Collection

Health inequities based on geographic differences and between rural and urban populations in modern India demonstrate the stark differences in health access and community development throughout the country. More than 70% of the Indian population lives in rural areas, and yet a greater proportion of health care spending is devoted to urban populations. In 2004-5, 29.2% of both central and state public expenditures were allocated to urban allopathic services while 11.8% went to rural allopathic services (Balarajan, Selvaraj, and Subramanian 2011, 508). There are more than twice as many government beds in urban than in rural areas and geographic distribution …

Creating Dignity Out Of Despair: The Impact Of The 2009 Decriminalization Of Homosexuality In Delhi, Diana Boesch

Independent Study Project (ISP) Collection

Section 377 of the Indian Penal Code was created in 1860 and outlawed “carnal intercourse against the order of nature.” In the following years, even after independence, India used Section 377 to prosecute child sexual abusers. While the law was rarely used to prosecute adult same-sex intercourse, it created widespread homophobia and harassment for LGBT Indians. Finally, in 2001 the Naz Foundation filed a petition against Section 377. On July 2, 2009 the Delhi High Court struck down Section 377 in its application to adult consensual same-sex intercourse. The decision sparked celebration within the LGBT community, a massive media response, …

Prettiest In Pink? Dutch Teenage Girls And Femininity, Leah Allen

Independent Study Project (ISP) Collection

This report is the result of a month-long qualitative examination of the various attitudes held by Dutch teenage girls on feminine behavior and presentation. Background research included examining work written about Dutch women and Dutch teen girl culture, as well as analyzing two Dutch teen magazines, Meiden and Girlz. I interviewed five Dutch girls from the ages of 13 to 17 about the acceptability and prevalence of femininity and “girliness” among them and their peers. I concluded that these Dutch girls believe that it is most acceptable for a girl to act in a certain way based on her gender: …

Serbian/Albanian Bilingualism In Kosova: Reversal Or Entrenchment Of The Curse Of Babel?, Sarah Littisha Jansen

Independent Study Project (ISP) Collection

Dynamics of power between multiple languages in one space are indicative of and inform the relationship between the speakers of those languages. In post-conflict Kosova, two ethno-linguistic groups, Kosovar Serbians and Kosovar Albanians, live in a context where language has become politicized and long-standing linguistic, political, and social hierarchies of power have been radically disturbed. This paper describes the myriad of images of the Serbian language in the country, focusing particularly on those that come from the Serbian/Albanian bilingual Kosovar Albanian community. It then discusses how these inform language as a political tool and what the consequences of this are …

Control Biologico De La Broca Del Cafe (Hypothenemus Hampei) En La Valle De Vilcabamba, Loja, Ecuador. Una Comparacion De Huertas Usando El Hongo Beauveria Bassiana, María Mugnani

Independent Study Project (ISP) Collection

Today coffee has become one of the most popular beverages in the world and is cultivated in many countries. However, in recent years many areas of production, for example in the province of Loja, Ecuador in the valley of Vilcabamba, many are experiencing a threat in the form of a small Coleoptera species. Hypothenemus hampei, also known as la broca de café, passes the majority of its life cycle within the coffee berries and in the process of reproduction and colonization it destroys the bean that makes the beverage. This destruction of the bean no only affects the consumer, …

Criss Library Faculty Proceedings & Presentations

This article offers a theoretical model of online, graduate student information seeking behavior. The qualitative methodology used to gather data for the development of the model included an electronic survey and semi-structured interviews conducted online using Adobe Connect Pro™. Participating in the study were 238 graduate students enrolled in at least one online course at a mid-western university. Data analysis included use of Zoomerang™ reports to interpret survey data, and content analysis of interview transcriptions. The resulting evolution of the Bates’ (2002) theoretical model includes new two modes of information seeking: scrutinizing (directed, dynamic), and being alert (undirected, dynamic). The …

A Tale Of Two Sciences, Erin Murphy

Michigan Law Review

It was the best of times, it was the worst of times . .. . So might one describe the contrasting portraits of DNA's ascension in the criminal justice system that are drawn in David Kaye's The Double Helix and the Law of Evidence and Sheldon Krimsky and Tania Simoncelli's Genetic Justice: DNA Data Banks, Criminal Investigations, and Civil Liberties. For Kaye, the double helix stands as the icon of twenty-first-century achievement, a science menaced primarily by the dolts (lawyers, judges, and the occasional analyst) who misuse it. For Krimsky and Simoncelli, DNA is a seductive forensic tool that is …

Aerobic Biotransformation Of Alkyl Branched Aromatic Alkanoic Naphthenic Acids Via Two Different Pathways By A New Isolate Of Mycobacterium., Richard J. Johnson, Charles E. West, Aisha M. Swaih, Ben D. Folwell, Ben E. Smith, Steven J. Rowland, Corinne Whitby

More Faculty of Science and Engineering Research

Naphthenic acids (NAs) are complex mixtures of carboxylic acids found in weathered crude oils and oil sands, and are toxic, corrosive and persistent. However, little is known about the microorganisms and mechanisms involved in NA degradation. We isolated a sediment bacterium (designated strain IS2.3), with 100% 16S rRNA gene sequence identity to Mycobacterium aurum, which degraded synthetic NAs (4'-n-butylphenyl)-4-butanoic acid (n-BPBA) and (4'-t-butylphenyl)-4-butanoic acid (t-BPBA). n-BPBA was readily oxidized with almost complete degradation (96.8% ± 0.3) compared with t-BPBA (77.8% ± 3.7 degraded) by day 49. Cell counts increased fourfold by day 14 but decreased after day 14 for both …

P53 Expression In Oropharyngeal Squamous Cell Carcinoma In Increased In Hpv Positive Smokers, Madalina Tuluc, Voichita Bar-Ad, Zi-Xuan Wang, Joseph Curry

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Background and Objectives

High risk HPV is associated with oropharyngeal SCC (OSCC) and is responsible for the increasing incidence of this cancer type among younger patients.

Patients with HPV positive oropharyngeal SCC have a better prognosis when compared with HPV negative, tobacco induced SCC.

HPV E6 inactivates p53 leading to low expression of p53; tobacco induced oropharyngeal SCC is characterized by p53 overexpression, resistance to treatment and poor prognosis. However, in many cases of HPV OSCC, there is a history of current or remote smoking, making this disease a multifactorial process. We expect that smoking will influence the level of …

Global Sleep Quality As A Moderator Of Alcohol Consumption And Consequences In College Students, Shannon R. Kenney, Joseph W. Labrie, Justin F. Hummer, Andy T. Pham

Heads Up!

The authors examined the relationship between global sleep quality and alcohol risk, including the extent to which global sleep quality moderated the relationship between alcohol use and drinking-related consequences. Global sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) and alcohol-related consequences were assessed using the Rutgers Alcohol Problem Index (RAPI). The sample consisted of 261 college students (61.3% female, 58.2% Caucasian) who completed online surveys. Using a four-step hierarchical multiple regression model, global sleep quality was found to predict alcohol consequences, over and above assessed covariates (demographics and weekly drinking). Further, global sleep quality emerged as a …

Practicing Paradise: Contemplative Awareness And Ecological Renewal, Douglas E. Christie

Theological Studies Faculty Works

What would it mean for Christians to take seriously the idea that we are called to practice paradise, to inhabit the world as if “everything is in fact paradise”? In the Christian contemplative tradition, one finds recurring attention to the notion that paradise is somehow knowable, graspable, and inhabitable in this present reality, and that this experience of paradise can be incorporated into a meaningful spiritual practice. This essay asks whether, in a moment of deepening ecological degradation, the contemplative practice of paradise might help us learn again how to imagine the world as whole, inhabit it with tenderness and …
