Elections And Economic Turbulence In Brazil: Candidates, Voters, And Investors, Tony Petros Spanakos, Lucio R. Renno
Elections And Economic Turbulence In Brazil: Candidates, Voters, And Investors, Tony Petros Spanakos, Lucio R. Renno
Department of Political Science and Law Faculty Scholarship and Creative Works
The relation between elections and the economy in Latin America might be understood by considering the agency of candidates and the issue of policy preference congruence between investors and voters. The preference congruence model proposed in this article highlights political risk in emerging markets. Certain risk features increase the role of candidate campaign rhetoric and investor preferences in elections. When politicians propose policies that can appease voters and investors, elections may have a limited effect on economic indicators, such as inflation. But when voter and investor priorities differ significantly, deterioration of economic indicators is more likely. Moreover, voter and investor …

Prostate cancer is the most frequently diagnosed cancer in males in the United States, accounting for an estimated 186,320 new cases in 2008. There are striking racial or ethnic differences in prostate cancer incidence and mortality rates in the United States, with Black males 1.6 times more likely to be diagnosed and 2.4 times more likely to die with prostate cancer than Whites. The stage at diagnosis is a key prognostic factor for prostate cancer survival, with African-Americans generally diagnosed at a more advanced stage. To identify factors that explain the race-stage disparity in prostate cancer, we conducted a population-based …

Incidence rates for adenocarcinomas of the esophagus and gastric cardia have been increasing rapidly, while rates for non‐cardia gastric adenocarcinoma and esophageal squamous cell carcinoma have declined. We examined food group intake as a risk factor for subtypes of esophageal and gastric cancers in a multicenter, population‐based case–control study in Connecticut, New Jersey and western Washington state. Associations between food groups and risk were estimated using adjusted odds ratios (OR), based on increasing intake of one serving per day. Total vegetable intake was associated with decreased risk of esophageal adenocarcinoma (OR = 0.85, 95% CI = 0.75, 0.96). Conversely, total …

The purpose of this study was to create and establish the validity of a short questionnaire to measure mothers' perceived support for breastfeeding from the workplace. The items in the workplace breastfeeding support scale (WBSS) were derived from a literature review. The scale was self-administered in central Indiana during the fall of 2005 to a convenience sample of 66 volunteers who were primiparous, 6 to 12 months postpartum, worked outside the home and had initiated breastfeeding prior to the survey. Internal consistency (α) and split-half reliability (r) test and factor analysis were done to establish reliability and construct …
Response Of The Salt Gland Of The Insectivorous Lizard Novoeumeces Schneideri To Ionic And Osmotic Challenges, Claudia Lechuga
Response Of The Salt Gland Of The Insectivorous Lizard Novoeumeces Schneideri To Ionic And Osmotic Challenges, Claudia Lechuga
Theses, Dissertations and Culminating Projects
The reptilian kidney can only produce isoosmotic waste. To supplement renal ion excretion and maintain ionic and osmoregulation, some reptile species rely on extrarenal salt glands that can secrete a hyperosmotic solution. Extrarenal glands among reptile taxa include the cranial gland in lizards, lacrimal gland of marine turtles, and sublingual gland of the estuarine crocodile and sea snakes. Secretion composition varies among these taxa, depending on diet, osmotic load and phylogeny. The salt glands of lizards are unique among reptiles in their ability to vary composition of the secreted fluid, secreting cations (potassium and/or sodium) and anions (chloride and/or bicarbonate). …
Optimization Of Expression And Purification Of Acetoacetyl-Coa Thiolase From Sunflower, Anthony Muriithi Maina
Optimization Of Expression And Purification Of Acetoacetyl-Coa Thiolase From Sunflower, Anthony Muriithi Maina
Theses, Dissertations and Culminating Projects
The [beta]-oxidation system in sunflower (Helianthus annuus L.) cotyledons is distinguished by the existence of two different thiolase isoforms, Thiolase I (acetoacetyl-CoA thiolase, EC 2.3.1.9 AACT) and Thiolase II (3-oxoacyl-CoA thiolase, EC 2.3.1.16 OACT). Glyoxysomal AACT is the last enzyme in the p-oxidation of fatty acids in plant glyoxysomes. Glyoxysomal AACT has been successfully cloned, expressed and purified from sunflower cotyledons (Dyer et al., 2006). In this paper we investigate the optimal conditions for both expression and purification. These include the choice of vector, the growth conditions and the purification parameters for the maximum possible yield of AACT protein.
Identification Of Metallo-Ss-Lactamase Inhibitors Via Enzyme Assay And Hplc-Ms Monitoring, Peggy Ann Sanchez
Identification Of Metallo-Ss-Lactamase Inhibitors Via Enzyme Assay And Hplc-Ms Monitoring, Peggy Ann Sanchez
Theses, Dissertations and Culminating Projects
The vast overuse of antibiotics along with extrachromosomal gene insertion between different bacterial species has led to the Darwinian consequence of antibiotic resistance. Amongst the contributing factors to the rise of bacterial resistances are the production of ß-lactamases, which pose a major impediment to treatment with ß-lactam drugs such as penicillins and carbapenems. SPM-1 is a metallo-ß-lactamase (MBL) that confers antibiotic resistance to bacteria through zinc-mediated hydrolysis of ß-lactams. Bacteria that express the SPM-1 metalloenzyme show reduced sensitivity to ß-lactam drugs. One method to defeat this form of resistance is to administer a ß-lactam antibiotic with a potent ß-lactamase inhibitor …

We examined the psychometric properties of the newly created Counterfactual Thinking for Negative Events Scale (CTNES) in two studies involving university undergraduates. In Study 1 (N = 634), factor analysis revealed four subscales that correspond with various types of counterfactual thinking: Nonreferent Downward, Other-Referent Upward, Self-Referent Upward, and Nonreferent Upward. The subscales were largely orthogonal and had adequate internal consistency and test–retest reliability. The CTNES subscales were positively correlated with a traditional method of assessing counterfactual thinking and were related as expected to contextual aspects of the negative event, negative affect, and cognitive style. In Study 2 (N …
Cross-Modal Interaction Between Vision And Hearing: A Speed—Accuracy Analysis, Yoav Arieh, Lawrence E. Marks
Cross-Modal Interaction Between Vision And Hearing: A Speed—Accuracy Analysis, Yoav Arieh, Lawrence E. Marks
Department of Psychology Faculty Scholarship and Creative Works
Cross-modal facilitation of response time (RT) is said to occur in a selective attention task when the introduction of an irrelevant sound increases the speed at which visual stimuli are detected and identified. To investigate the source of the facilitation in RT, we asked participants to rapidly identify the color of lights in the quiet and when accompanied by a pulse of noise. The resulting measures of accuracy and RT were used to derive speed-accuracy trade-off functions (SATFs) separately for the noise and the no-noise conditions. The two resulting SATFs have similar slopes and intercepts and, thus, can be treated …

Evidence For Low Levels Of Genetic Variation Among Zostera Marina Populations From The Atlantic West Coast, Eric Rosenzweig
Evidence For Low Levels Of Genetic Variation Among Zostera Marina Populations From The Atlantic West Coast, Eric Rosenzweig
Theses, Dissertations and Culminating Projects
Zoster a marina (eelgrass), can be found in the North Atlantic on the coast of Europe and the North Arctic, as well as the Pacific. On the Atlantic west coast this species grows as far south as North Carolina and into northern Canada. The cold waters of these regions support the habitat needed for the species. Eelgrass is vital to coastal communities. It serves as a food source for many organisms, hatching ground for fish species, absorbent of water pollutants, and soil stabilizer. Over the last 30 years, the once robust populations of Atlantic west coast eelgrass have withered into …
Comparative Study Between Wild Rice (Oryza Rufipogon) And Domesticated Rice (Oryza Sativa Ssp Japonica) Chromosome 8 Centromere, Soham Aso
Theses, Dissertations and Culminating Projects
Rice has one of the simplest of the monocotyledonous genomes analyzed to date. The Oryza sativa genome is made of 12 chromosomes and has a total length of 430 MB. It is highly syntenic amongst other cereals. Therefore, genetic distances of these organisms are surprisingly very similar, meaning that genomic recombinations in each cereal occur at much the same frequency despite the differences in their genome size. The reason for this synchrony in recombinations may be due to similar lengths of gene-rich and gene-rare regions. This study focuses on the gene-rare repetitive centromeric region of rice chromosome 8. Although the …
Nutritional Evaluation Of Lean And Non-Lean Female High School Athletes Using Mypyramid, William Edward Mcsheffrey
Nutritional Evaluation Of Lean And Non-Lean Female High School Athletes Using Mypyramid, William Edward Mcsheffrey
Theses, Dissertations and Culminating Projects
MyPyramid was used to evaluate the nutritional status of twelve lean and fourteen non-lean high school female athletes. Lean athletes are those who participate in sports where weight control is considered important for performance. Weights of athletes participating in non-lean sports are less likely to influence performance. In this study, all the lean sport athletes participated in track, and the non-lean athletes competed in softball. Subjects included twenty-five middle-class Caucasians and one Hispanic from two northern New Jersey high schools. All subjects and their parents gave their consent to participate. Subjects needed to be in good health, between the ages …
