Surface Attachment Of Active Antimicrobial Coatings Onto Conventional Plastic Based Laminates And Performance Assessment Of These Materials On The Storage Life Of Vacuum Packaged Beef Sub-Primals, D. Clarke, A. Tyuftin, M. Cruz-Romero, D. Bolton, S. Fanning, S. K. Pankai, Carmen Bueno-Ferrer, Patrick J. Cullen, J. P. Kerry

Articles

Two antimicrobial coatings, namely Sodium octanoate and Auranta FV (a commercial antimicrobial composed of bioflavonoids, citric, malic, lactic, and caprylic acids) were used. These two antimicrobials were surface coated onto the inner polyethylene layer of cold plasma treated polyamide films using beef gelatin as a carrier and coating polymer. This packaging material was then used to vacuum pack beef sub-primal cuts and stored at 4 °C. A control was prepared using the non-coated commercial laminate and the same vacuum packaged sub-primal beef cuts. During storage, microbial and quality assessments were carried out. Sodium octanoate treated packages significantly (p < 0.05) reduced microbial counts for all bacteria tested with an increase of 7 and 14 days, respectively compared to control samples. No significant effect on pH was observed with any treatment. The results suggested that these food grade antimicrobials have the potential to be used in antimicrobial active packaging applications for beef products.

The Antibacterial Activity Of Metal Complexes Containing 1, 10-Phenanthroline: Potential As Alternatire Therapeutics In The Era Of Antibiotic Resistance, Livia Viganon, Orla L. Howe, Pauraic Mccarron, Malachy Mccann, Michael Devereux

Articles

The “antibiotic era”, characterized by the overuse and misuse of antibiotics, over the last half-century has culminated in the present critical “era of resistance”. The treatment of bacterial infections is challenging because of a decline in the current arsenal of useful antibiotics and the slow rate of new drug development. The discovery of a new gene (mcr-1) in 2015, which enables bacteria to be highly resistant to polymyxins (such as colistin), the last line of antibiotic defence left, heralds a new level of concern as this gene is susceptible to horizontal gene transfer, with alarming potential to be spread between …

Laser-Induced Breakdown Spectroscopy (Libs) For Food Analysis: A Review, Maria Markiewicz-Keszycka, Xavier Cama-Moncunill, Maria Piedad Casado-Gavalda, Yash Dixit, Raquel Cama-Moncunill, Patrick J. Cullen, Carl Sullivan

Articles

Background Laser-induced breakdown spectroscopy (LIBS) is an atomic emission spectroscopic technique which uses a focused pulsed laser beam to generate plasma from the material. The plasma contains atoms, ions and free electrons which emit electromagnetic radiation as the plasma cools down. The emitted light is resolved by a spectrometer to form a spectrum. Recently, LIBS has become an emerging analytical technique for characterisation and identification of materials; its multi-elemental analysis, fast response, remote sensing, little to no sample preparation, low running cost and ease of use make LIBS a promising technique for the food sector.

Attitudes About Women, Sexuality, And Abortion, Phoebe Xoxakos, Kathryn R. Klement, Brad J. Sagarin

Faculty Articles, Papers, and Other Scholarship

Abortion currently and throughout history, has been a wide-spread, controversial topic, though one in three women will obtain abortion services by the time they are 45 (Guttmacher Institute, 2014). Even after the U.S. Supreme Court affirmed a woman’s right to undergo an abortion in the famous Roe vs. Wade (1973) case, state-wide laws and restrictions continue to be placed on abortion practices (Begun & Walls, 2014). Many Americans support and/or oppose the act of having an abortion based on their personal beliefs and attitudes on how women should conduct themselves in different situations, and Wolf (1991) points out that advocates …

Formal Declarations Of Intended Childcare Parentage, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

Legal parentage for childcare purposes under American state laws is significantly and rapidly expanding, with the new norms growing increasingly imprecise. No longer is childcare parentage, that is, parentage carrying the superior right to the “care, custody, and control” of a child, only defined at precise moments in time, as by giving birth; having biological ties; marriage to the birth mother; name placement on a birth certificate; or, formal adoption. In increasing numbers, both men and women are now becoming childcare parents where the time of the actions prompting legal parentage is imprecise. Here, parentage typically depends on assessing earlier …

Nonparental Childcare And Child Contact Orders For Grandparents, Jeffrey A. Parness, Alexander Yorko

Faculty Articles, Papers, and Other Scholarship

The U.S. Supreme Court has long recognized that the regulation of certain areas of domestic relations, including standing to seek a childcare order, rests within the virtually exclusive province of the states. State lawmakers recently have undertaken many new domestic relations initiatives relevant to parental and nonparental childcare, prompted by new forms of human reproduction, large numbers of nonmarital births, and shifts in in family structures. In this article we review past, current and future state lawmaking on the availability of nonparental childcare and child contact orders for grandparents. Our work coincides with the current inquiries into new model childcare …

State Lawmaking On Federal Constitutional Childcare Parents: More Principled Allocations Of Powers And More Rational Distinctions, Jeffrey A. Parness

Faculty Articles, Papers, and Other Scholarship

Unlike other federal constitutional rightsholders, a parent with the federal constitutional right to exercise “care, custody, and control” over a child is defined by state lawmakers. While federal constitutional childcare parents may be defined by state constitutional law precedents, they typically are not. The balance of General Assembly and judicial authority over childcare parentage definitions varies interstate. As well, the definitions of childcare parentage differ intrastate depending upon how parentage is established. At times, childcare parentage is defined in a single state by biological ties (real or imagined), contracts, or earlier histories of significant parental-like acts. When determining federal constitutional …

A Self-Regulatory Perspective Of Work-To-Home Undermining Spillover/Crossover: Examining The Roles Of Sleep And Exercise, Larissa K. Barber, Shannon G. Taylor, James P. Burton [email protected], Sarah F. Bailey

Faculty Articles, Papers, and Other Scholarship

Research demonstrating that employees who are undermined at work engage in similar behavior at home suggests this connection reflects displaced aggression. In contrast, the present study draws on self-regulation theory to examine the work-home undermining spillover/crossover process. We propose that poor sleep quality transmits the influence of workplace undermining to home undermining per self-regulatory impairment, and exercise moderates this indirect effect per self-regulatory improvement. Using matched data from 118 employees and a member of their household to test our model, results demonstrated that undermining experienced from supervisors increased subjective (i.e., self-reported) but not objective (i.e., actigraph-recorded) sleep difficulties, which in …

The Nutritional Quality Of Non-Calcified Macroalgae In Guadeloupe (Lesser Antilles) Evaluated By Their Biochemical Composition, Charlotte Reine Dromard, Yolande Bouchon-Navaro, Mireille Harmelin-Vivien, Claude Bouchon

Gulf and Caribbean Research

Biochemical compositions of 15 species and 1 genus of macroalgae were studied. Concentrations of macronutrients were measured to evaluate their nutritional quality. High concentrations of proteins, lipids and soluble carbohydrates generally indicate a high nutritional quality because these compounds are readily metabolically available for consumers and provide a large proportion of energy. Insoluble carbohydrates are more difficult to digest and high concentrations indicate a low nutritional quality.

Three groups of macroalgae were identified according to their biochemical characteristics. The first group clusters Ceramium cf nitens, Ulva cf lactuca and Lobophora cf variegata due to their high concentrations of proteins …

From Wearing To Wondering: Treating Wearable Activity Trackers As Objects Of Inquiry, Joel R. Drake, Ryan Cain, Victor R. Lee

Instructional Technology and Learning Sciences Faculty Publications

Wearable technologies represent a rapidly expanding category of consumer information and communications technologies. From smartwatches to activity tracking devices, wearables are finding their way into many aspects of our lives, changing the way we think about ourselves and the world around us. The rapid adoption of these tools in everyday life hints at the possibilities these devices may hold in school and other educational settings. Drawing on examples taken from a five-year study using wearable fitness tracking devices in elementary and middle school classrooms, this paper presents two examples of how wearable devices can be appropriated for use in school …

Performing Gender: An Exploration Of The Relationship Between Expression And Identity, Allegra Barnes

Scripps Senior Theses

This paper discusses the relationship between gender expression and gender identity. It recounts my personal exploration of the two through the process of photographing two fellow AFAB individuals to create visual representations of their gender expressions while interviewing them to examine how these expressions relate to the gender with which they identify. Following this, I engage in self-reflection taking into consideration both the narratives of my peers as well as Judith Butler's insights on gender. The project culminates with a series of self portraits and a conclusion on how I came to understand both facets my gender.

Quantifying Carbonyl Sulfide And Other Sulfur-Containing Compounds Over The Santa Barbara Channel, Julia Black

Scripps Senior Theses

Carbonyl sulfide (OCS) is emitted to the atmosphere through the outgassing of ocean surface waters. OCS is also the primary source of sulfur-containing compounds in the stratosphere and contributes to the formation of the stratospheric sulfate layer, an essential controller of the radiative balance of the atmosphere. During the 2016 Student Airborne Research Program (SARP), 15 whole air samples were collected on the NASA DC-8 aircraft over the Santa Barbara Channel. Five additional surface samples were taken at various locations along the Santa Barbara Channel. The samples were analyzed using gas chromatography in the Rowland-Blake lab at UC Irvine, and …

Evolving Art: Modifying Context Free Art With A Genetic Algorithm, Marina Kent

Scripps Senior Theses

Context Free Design Grammar (CFDG) is a programming language for defining recursive structures that can be used to create art. I use CFDG as a design space for genetic programming, experimenting with various options for crossover, mutation, and fitness. In this exploratory work, multiple generations are manually assessed to determine the usefulness of the mutation strategies and fitness functions. I find that simple value mutation and fitness that alters general program structure is not enough to produce an increase of interesting images in CFDG. I discuss these findings as well as future avenues of inquiry for genetic programming in artistic …

Are You Feeling Me?: The Role Of Attention In Physiological Empathetic Responses, Gabriela Paganini

Scripps Senior Theses

This study examined the role of attention and trait empathy within the production of neural facial mimicry responses that have been previously found to be associated with the experience of empathy. More specifically, do people who have high trait empathy levels require less attention to emotional information in order to still exhibit these physiological responses than people who have lower trait empathy levels? It has previously been demonstrated that responses in the zygomaticus and corrugator muscles have been associated with the experience of empathy. College aged participants were shown series of happy, angry, and neutral faces with the amount of …

Consult, Consent, And Veto: International Norms And Canadian Treaties, Shin Imai

Articles & Book Chapters

Large parts of Canada, from Ontario to parts of British Columbia and north to the Northwest Territories, are covered by the “numbered treaties”, signed between First Nations and the Crown between 1871 and 1929. These treaties provide for the continuation of Indigenous hunting, fishing and harvesting activities until the land is “taken up” by the provincial Crown for activities such as mining, lumbering and settlement. This draft book chapter argues that consent of First Nations should be required before further development that impact on their harvesting rights. The consent standard has already been widely adopted in the private sector both …

Sanders-Brown Center on Aging Faculty Publications

Background

Great heterogeneity exists in survival and the interval between onset of motor symptoms and dementia symptoms across synucleinopathies. We aimed to identify genetic and pathological markers that have the strongest association with these features of clinical heterogeneity in synucleinopathies.

Methods

In this retrospective study, we examined symptom onset, and genetic and neuropathological data from a cohort of patients with Lewy body disorders with autopsy-confirmed α synucleinopathy (as of Oct 1, 2015) who were previously included in other studies from five academic institutions in five cities in the USA. We used histopathology techniques and markers to assess the burden of …

Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya

Turkish Journal of Botany

Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast …

Prosocial/Civic Interests, Prosocial/Civic Behaviors, And Participation In The Arts, Donald J. Polzella

Psychology Faculty Publications

Executive Summary

A useful strategy for understanding the benefits of participating in the arts is to focus on audience members rather than on artists or performers (Brown & Novak, 2007). Previous research employing this strategy provided a framework for the present study. Polzella & Forbis (2013, 2014) used logistic regression to analyze data from 6257 households who took part in the 2008 Survey of Public Participation in the Arts (SPPA). Three pro-social behaviors (voting in the 2004 presidential election, making charitable donations or volunteering time, and attending community meetings) were regressed on what the NEA considers “traditional” music audience participation …

Pathways And Supply Of Dissolved Iron In The Amundsen Sea (Antarctica), P. St-Laurent, P. L. Yager, R. M. Sherrell, S. E. Stammerjohn, M. S. Dinniman

CCPO Publications

Numerous coastal polynyas fringe the Antarctic continent and strongly influence the productivity of Antarctic shelf systems. Of the 46 Antarctic coastal polynyas documented in a recent study, the Amundsen Sea Polynya (ASP) stands out as having the highest net primary production per unit area. Incubation experiments suggest that this productivity is partly controlled by the availability of dissolved iron (dFe).As a first step toward understanding the iron supply of the ASP, we introduce four plausible sources of dFe and simulate their steady spatial distribution using conservative numerical tracers. The modeled distributions replicate important features from observations including dFe maxima at …

Fish Spawning Aggregations: Where Well-Placed Management Actions Can Yield Big Benefits For Fisheries And Conservation, Brad Erisman, William Heyman, Shinichi Kobara, Tal Ezer, Simon Pittman, Octavio Aburto-Oropeza, Richard S. Nemeth

CCPO Publications

Marine ecosystem management has traditionally been divided between fisheries management and biodiversity conservation approaches, and the merging of these disparate agendas has proven difficult. Here, we offer a pathway that can unite fishers, scientists, resource managers and conservationists towards a single vision for some areas of the ocean where small investments in management can offer disproportionately large benefits to fisheries and biodiversity conservation. Specifically, we provide a series of evidenced-based arguments that support an urgent need to recognize fish spawning aggregations (FSAs) as a focal point for fisheries management and conservation on a global scale, with a particular emphasis placed …

Development Of An Age-Frequency Distribution For Ocean Quahogs Arctica Islandica On Georges Bank, Sara M. Pace, Eric N. Powell, Roger Mann, M. Chase Long, John M. Klinck

CCPO Publications

Ocean quahogs [Arctica islandica (Linnaeus, 1769)] are the longest-lived, noncolonial animal known today, with a maximum life span exceeding 500 y. Ocean quahogs are a commercially important bivalve, inhabiting the continental shelf of the North Atlantic Basin. Although considerable information exists on the growth and physiology of A. islandica, limited information is available regarding recruitment; accordingly, sustainably managing the fishery is a challenge. To investigate long-term recruitment trends, the age of ocean quahogs from Georges Bank which were fully recruited to the commercial fishery (>80 mm shell length) was determined by analysis of annual growth lines in …

Variation In Cranial Morphology Of Polymorphic Populations Of The Eastern Red-Backed Salamander, Plethodon Cinereus, Marissa Ganzfried

Masters Theses

Differences in cranial morphology among species of plethodontid salamanders have been linked to variations in diet and behavior. Individuals that consume smaller prey have larger jaw to posterior-cranium ratios. Elongation and expansion of the jaw, coupled with expansion of the posterior of the cranium (defined as robustness) are positively associated with individuals that exhibit increased levels of aggression. The bulk of previous research has focused on the effects of interspecific competition on cranial morphology; however, polymorphic populations of the Eastern Red-backed Salamander, Plethodon cinereus, represent a unique opportunity to examine the role of cranial morphology in ecological divergence among individuals …

Aligning Business Decision Making To Strategy, Donald J. Barnes, Katherine A. Dominguez, Whitney J. Vazquez

Theses

"Hurry up and wait" is a recipe for inefficiency. Some product development projects start and stop and start again, with team members being added and removed throughout the process. The cost of this lurching does not appear to be well quantified. Moving technical talent from one project to another may assume 100% engineering efficiency, which is not case. Hidden effects of engineers being moved include having to "spin up" on the new project and learn where the last team members left off (which may not be well documented), repeating initial work, and lowered efficiency and morale on the part of …

Mentoring Generation X Women: Program Elements To Increase Success For Principals Or Nonprofit Leaders, Mollie A. Bond

All Capstone Projects

Mentoring may encourage leadership development in Generation X women who wish to gain leadership positions in nonprofit sector organizations or school administrations. However, cultural values and female natural tendencies may form a glass ceiling for females seeking leadership roles. This qualitative study asked 11 women about their experiences in mentoring programs to determine if what elements are necessary for mentoring programs to help female Generation Xers be successful. Participants were mentored by females in one of two programs: the Chicago Women in Philanthropy (CWIP) Women’s Leadership Mentoring Program (WLMP) or the Metropolitan Institute for Leadership in Education (MILE) Principal Mentor …

Immunotherapy Against Drugs Of Abuse, Gianna Raimondi (Class Of 2017)

Writing Across the Curriculum

Current treatments for drug addiction involve classical pharmacological therapy, involving the use of competitive or noncompetitive agonists (full, partial, or inverse) and antagonists. Drugs of abuse enter the brain after crossing the blood-brain barrier rapidly and binding to the proper receptor(s). They are able to do so because they are small and lipid soluble, and produce reinforcing effects by increasing levels of dopamine in brain areas associated with reward. This occurs in specific systems associated with addiction. In the mesolimbic system, neuron cell bodies originate in the ventral tegmental area (VTA) and project to the nucleus accumbens (NAc), amygdala, hippocampus, …

Application Of Factorial Design In The Analysis Of Factors Influencing Textile Dye Adsorption On Activated Carbon, Eid A. Alkhatib, Penny A. Snetsinger, Ahmad Alanazi, Sarah Aanonsen

Chemistry & Physics Faculty Publications

In this study, the use of factorial design software is applied to evaluate efficiently factors influencing the adsorption capacity of activated carbon in treating textile dyes. Activated carbon is usually used to treat wastewater effluents from textile industries in order to remove textile dyes before discharge into the environment. Most treatment facilities, particularly large industrial or wastewater treatment facilities use continuous flow reactors or packed columns to treat the dye. Due to the limited residence time in these types of reactors, adsorption equilibrium is not necessarily reached, and the absorption rate becomes an important factor in this treatment process. Other …

Aging Athletes, Broken Bodies, And Disability In Jack London's Prizefighting Prose, Cara E. Kilgallen

English Faculty Publications

Jack London's name often conjures up images of dogs plowing through Alaska's desolate wilderness, or of robust men journeying into the wild; however, pictures of broken bodies struggling for survival in a boxing ring less readily come to mind. Few think of London as a sports writer, yet his illustrations of prizefighting reveal an author interested not only in able bodied athletes but in disabled and weakened ones as well. Although he is best known for his Klondike stories, nautical adventures, and socialist sentiments, the author's fascination with fitness shows that sport and the body are just as central to …
