Can Curriculum Changes Improve The Deliverables The Business Studies Departments Of Maine’S Community Colleges Provide Its Stakeholders?, Jack Buckley Ma

All Student Scholarship

Recent seminars and meetings between state officials and business leaders have established that a perceived disconnect exists between the skill's, knowledge, and abilities needed by their enterprises and the skill's, knowledge, and abilities being taught by the state’s educational systems. The Maine Community College System's vision states that the system answers to a number of stakeholders by providing a two year comprehensive, affordable, and accessible college education..." dedicated to building a quality workforce for Maine” (Maine Community College, n.d.). While the MCCS is a relatively new institution, this suggests that the community college arena is the most logical starting place …

Betwixt And Between Past And Present: Cultural And Generic Hybridity In The Fiction Of Mary Yukari Waters, Rania Samir Youssef

Asian American Literature: Discourses & Pedagogies

The cosmopolitan make-up of the American society has yielded cultural hybrid offspring and this cultural hybridity features strongly in contemporary American fiction. Amy Tan and Mary Yukari Waters are both Asian-Americans who portray such hybridity in their short stories which depict the shifting identities of the self. But do the internal categories of gender, race and ethnicity help in the coherence or do they add to the fragmentation of diverse identities? It is the dynamics of this critique of multiple identification and hybrid cultures that is being traced here in this study and how all this is reflected in narrative …

Present And Potential Future Distribution Of Common Vampire Bats In The Americas And The Associated Risk To Cattle, Dana N. Lee, Monica Papeş, Ronald A. Van Den Bessche

KIP Articles

Success of the cattle industry in Latin America is impeded by the common vampire bat, Desmodus rotundus, through decreases in milk production and mass gain and increased risk of secondary infection and rabies. We used ecological niche modeling to predict the current potential distribution of D. rotundus and the future distribution of the species for the years 2030, 2050, and 2080 based on the A2, A1B, and B1 climate scenarios from the Intergovernmental Panel on Climate Change. We then combined the present day potential distribution with cattle density estimates to identify areas where cattle are at higher risk for the …

Sharing Science: A Study On The Effects Of Informal Science Education Outreach With Elementary Students, Martha Jo Vargas, Diane L. Marshall, Teresa E. Sheldahl

Biology ETDs

Science education reform has prompted scientists, engineers, and politicians alike to act on the growing need for improved educational programs in the STEM fields. Informal science programs that provide an educational experience outside of a traditional classroom and involve students on real-life and hands-on experiments are among these initiatives. It is hypothesized that informal science programs may increase students interest and performance in science and related subjects. Here we evaluate this by assessing the impacts of one such program, the Junior Scientist Outreach Program (JSOP), a weeklong, free-of-cost camp with fourth and fifth grade students in a predominately Hispanic/Latino community …

Farnesol And Cyclic Amp Signaling Effects On The Hypha-To-Yeast Transition In Candida Albicans, Allia K. Lindsay, Aurélie Deveau, Amy E. Piispanen, Deborah A. Hogan

Dartmouth Scholarship

Candida albicans, a fungal pathogen of humans, regulates its morphology in response to many environmental cues and this morphological plasticity contributes to virulence. Farnesol, an autoregulatory molecule produced by C. albicans, inhibits the induction of hyphal growth by inhibiting adenylate cyclase (Cyr1). The role of farnesol and Cyr1 in controlling the maintenance of hyphal growth has been less clear. Here, we demonstrate that preformed hyphae transition to growth as yeast in response to farnesol and that strains with increased cyclic AMP (cAMP) signaling exhibit more resistance to farnesol. Exogenous farnesol did not induce the hypha-to-yeast transition in mutants …

Analysis Of Microbial Diversity By Amplicon Pyrosequencing, Ryan Legge

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Microorganisms numerically dominate terrestrial biodiversity, and play important biochemical and geochemical roles in the environments they inhabit. To understand structure and function of complex ecosystems, it is essential to identify primary drivers of microbial diversity and community structure. Historically, the study of microbial ecology was reductive, limited to microbes able to be cultured and enumerated. Microbes meeting this criterion were thought to comprise the dominating members of the environments they were isolated from, however, estimates suggesting up to 99% of the endogenous species are uncultivable with existing methodologies; a concept that reflects experimental failure, rather than a verifiable conclusion. Therefore …

Analyses Of Chromosome Copy Number And Expression Level Of Four Genes In The Ciliate Chilodonella Uncinata Reveal A Complex Pattern That Suggests Epigenetic Regulation, Laure Bellec, Laura A. Katz

Biological Sciences: Faculty Publications

Chilodonella uncinata, like all ciliates, contains two distinct nuclei in every cell: a germline micronucleus and a somatic macronucleus. The macronucleus develops from the zygotic nucleus through a series of chromosomal rearrangements. Macronuclear development in C. uncinata yields a nucleus with highly amplified gene-sized chromosomes. The macronucleus is transcriptionally active during vegetative growth while there is no expression in the micronucleus except during a brief period following conjugation. Gene family evolution in ciliates occurs through complex processes including gene duplication and an alternative processing of scrambled genes. Here we use quantitative PCR to compare relative expression levels of eight genes …

Biochemical Evaluation Of Srh Analogs As Potential Luxs Inhibitors, Richa Gupta

Master's Theses

Quorum sensing in bacteria is a process of cell-to-cell communication facilitated by small molecules called autoinducers. Interspecies quorum sensing is facilitated by the autoinducer AI-2. The enzyme LuxS catalyzes the formation of AI-2 from S-ribosyl homocysteine (SRH) in a wide variety of bacterial species. Inhibition of LuxS would therefore inhibit interspecies quorum sensing. The goal of this project is to establish biochemical assays for the evaluation of small molecules as potential LuxS inhibitors. The first assay is a conventional colorimetric assay that utilizes Ellman’s reagent to quantify the homocysteine byproduct of DPD production by LuxS. For this assay purified …

Assembly, Annotation, And Polymorphic Characterization Of The Erysiphe Necator Transcriptome, Jason Myers

Theses

The objectives of this study were to develop a transcriptomic reference resource and to characterize polymorphism between isolates of Erysiphe necator (syn. Uncinula necator), grape powdery mildew. The wine and fresh fruit markets are economically vital to many countries worldwide, and E. necator infection can cause severe crop damage and subsequent financial loss. Most of the publicly available sequence data for Erysiphales are from research done on Blumeria graminis f. sp. hordei, barley powdery mildew, which occupies a distinct clade within the Erysiphales. We obtained 641,601 sequencing reads from a Roche 454–FLX next–generation sequencer (RNA–Seq) and performed multiple assemblies using …

Chemical Constituents And Antiplasmodial Activity Of Indole Alkaloids From Ochrosia Oppositifolia / Mehran Fadaei Nasab, Mehran Fadaei Nasab

Student Works (2010-2019)

The chemical constituents of Ochrosia oppositifolia have been studied. The compounds were extracted from the bark and leaves of this plant by using n-hexane,dichloromethane and methanol as solvents. The crudes were subjected to extensive chromatographic techniques like preparative thin layer chromatography, column chromatography and high performance liquid chromatography (HPLC). A total of six compounds were obtained. Structural elucidation was established through several spectroscopic methods, such as 1D-NMR (1H, 13C, DEPT, NOE), 2D-NMR (COSY,NOESY, HMQC, and HMBC), UV, IR, and MS (GCMS, LCMS and HRMS) and comparison with the published data. Three compounds were isolated from the bark of Ochrosia oppositifolia, …

American Orientalism And Cosmopolitan Mixed Race: Early Asian American Mixed Race In The American Literary Imagination, Melissa Eriko Poulsen

Asian American Literature: Discourses & Pedagogies

This paper offers and initial examination of representations of Asian American mixed race during the long period of Asian exclusion and enforced anti-miscegenation when racial mixing was legally proscribed. I argue that this literature must be understood through two categories – Orientalist texts that produce and reproduce dominant discourses about Asian American mixed race and cosmopolitan texts written by mixed-race figures circling in vanguard cliques of art and literature. After tracking the representations of early Asian American mixed race in U.S. literature, this paper offers an analysis of the writing of Asian American mixed-race authors themselves in order to expand …

Disturbing Stereotypes: Fu Man/Chan And Dragon Lady Blossoms, Audrey Wu Clark

Asian American Literature: Discourses & Pedagogies

Article Submission (Accepted with Revisions): “Disturbing Stereotypes: Fu Man/Chan and Dragon Lady Blossoms” Article Abstract: In documenting anti-miscegenation laws in the United States, critic Sally L. Kitch argues that they were not only directed against mixed heritage African Americans but also against Asians after the Civil War. Kitch writes, “Fourteen states, including many that entered the Union after the war, adopted or revised anti-miscegenation statutes to apply to ‘Mongolians,’ or ‘Malays’ in general or to the Chinese in particular. Gender was also paramount to western lawmakers as they determined that the ‘blacks’ white women were most likely to marry were …

Excursus On "Hapa;" Or The Fate Of Identity, Nicole Myoshi Rabin

Asian American Literature: Discourses & Pedagogies

This paper focuses on the contradictions and tensions inherent in self-identification and oppositional identities. In the past twenty years, Hapa has emerged as an oppositional identity used by mixed-race Asian Americans. While many scholars have noted the tension of the term for its linguistic appropriation from the Native Hawaiian language, fewer scholars have concentrated their examinations on the ways in which the term reproduces the very notions it aims to subvert. This paper concentrates on the areas of contradiction inherent in finding and using "a word of power" and making that word into a recognizable identity.

A Hapa Family In Chekhov's Three Sisters, Elizabeth Liang

Asian American Literature: Discourses & Pedagogies

It is an act of courage or foolhardiness to produce theatre in the heart of the film world, depending on your point of view and how large the houses turn out to be. In the fall of 2005, I produced Three Sisters in a 60-seat theatre in Burbank, California (home of Disney and Warner Bros.). The odds were stacked even higher against the show's success when I stipulated that the main characters, the upper-class and highly educated Russian Prozorov siblings, had to be played by hapa actors. This essay describes my attempt to interpret the play through a multi-ethnic lens …

The Enhanced Pneumococcal Lamp Assay: A Clinical Tool For The Diagnosis Of Meningitis Due To Streptococcus Pneumoniae, Dong Wook Kim, Paul E. Kilgore, Eun Jin Kim, Soon Ae Kim, Dang Duc Anh, Bai Qing Dong, Jung Soo Kim, Mitsuko Seki

Department of Pharmacy Practice

Background: Streptococcus pneumoniae is a leading cause of invasive bacterial disease in developed and developing countries. We studied the loop-mediated isothermal amplification (LAMP) technique to assess its suitability for detecting S. pneumoniae nucleic acid in cerebrospinal fluid (CSF).

Methodology/Principal Findings: We established an improved LAMP assay targeting the lytA gene (Streptococcus pneumoniae [Sp] LAMP). The analytical specificity of the primers was validated by using 32 reference strains (10 Streptococcus and seven non-Streptococcus species) plus 25 clinical alpha-hemolytic streptococcal strains, including four S. pneumoniae strains and 21 other strains (3 S. oralis, 17 S. mitis, and …

A Comparison Of Methods For Measuring Co2 And O2, Jake Nelson

Techniques and Instruments

Understanding the dynamics of respiratory gasses gives critical insight into the metabolic processes of a biological system. An efficient and effective means of measuring respiration is essential to understanding aspects of the biosphere. Many methods have been developed for measuring changes in CO₂ and O₂, both as integrated systems and as individual components. Many experiments use an alkali trap with subsequent titration as an inexpensive method for CO₂ measurement. Haney et al. (2008) compared the titration method against infrared gas analysis (IRGA) and found them to be highly correlated, with r²=0.95. The use of …

Palmitoylation Regulates Intracellular Trafficking Of Β2 Adrenergic Receptor/Arrestin/Phosphodiesterase 4d Complexes In Cardiomyocytes, Ruijie Liu, Dayong Wang, Qian Shi, Qin Fu, Steven Hizon, Yang K. Xiang

Peer Reviewed Articles

β₂ adrenergic receptor (β₂AR) is a prototypical G-protein coupled receptor that stimulates the classic cAMP-protein kinase A (PKA) signaling pathway. Recent studies indicate that the cAMP-PKA activities are spatiotemporally regulated in part due to dynamic association of β₂AR with phosphodiesterase 4D (PDE4D), a group of cAMP degradation enzymes. Here, we demonstrate that in cardiomyocytes, palmitoylation of β₂AR, the covalent acylation of cysteine residue 341, plays a critical role in shaping subcellular cAMP-PKA activities in cardiomyocytes via regulating β₂AR association with arrestin/PDE4D. Replacing cysteine 341 on β₂AR with alanine (C341A) …

Ethics, Law, And The Science Of Fish Welfare, Colin Allen

Between the Species

Fish farming is one of the fastest growing sectors of agriculture, attracting considerable attention to the question of whether existing farming regulations and animal welfare laws are adequate to deal with the expanding role of fish in feeding humans. The role of fish as model organisms in scientific research is also expanding -- a majority of research biology departments now keep zebrafish for the purposes of genome biology, and they are used widely used for basic neuroscience research. However, due to their diversity and distance from mammalian biology, fish pose difficult questions for the application of legal and ethical principles …

Effectiveness Of Phosphorus Fertilizers In Hydroponics And Glasshouse Settings With Moderate And High Organic Matter Soils, Jeffrey Sean Christian Summerhays

Theses and Dissertations

Phosphorus (P) is poorly soluble in most soils and, thus, has poor plant uptake efficiency. AVAIL® and Carbond P (CBP) are new fertilizer products shown to increase P use efficiency (PUE) and increase crop yields when grown in P limiting soils. Carbond P has specifically been seen to increases P uptake and crop yields in soils low in P, although effectiveness in regards to soil organic matter is unknown. The objectives of these studies were to determine if the mode of action for these products is related to physiological response, to determine if Carbond P is toxic to plant roots …
