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 …

Organic Chemostratigraphic Markers Characteristic Of The (Informally Designated) Anthropocene Epoch, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Recognizing the tremendous collective impact of humans on the environment in the industrial age, the proposed designation of the current time period as the Anthropocene Epoch has considerable merit. One of the signature activities during this time continues to be the intensive extraction, processing, and combustion of fossil fuels. While fossil fuels themselves are naturally-occurring, they are most often millions of years old and associated with deeply buried strata. They may be found at the surface, for example, as natural oil seeps or coal seam outcrops, but these are relatively rare occurrences. Fossil fuels and their myriad by-products become the …

The Forum: Second Thoughts On Presidential Politics, Janet Ruane, Karen A. Cerulo

Department of Sociology Faculty Scholarship and Creative Works

In this essay, we confront the "conventional wisdoms" promoted throughout this long presidential campaign. By conventional wisdoms, we mean the common knowledge of politics - the things that commentators and analysts forward as taken-for-granted assertions and beliefs. We will revisit just a few of the campaign season's conventional wisdoms and review them with a sociological eye. In so doing, we find that in politics, as in most other areas, conventional wisdom can be a risky source of knowledge.

A Model To Use Denied Internet Traffic To Indirectly Discover Internal Network Security Problems, Chet Langin, Hongbo Zhou, Shahram Rahimi

Department of Computer Science Faculty Scholarship and Creative Works

We propose a model for using firewall log entries of denied inbound Internet traffic for indirect discovery of local IP addresses that have security problems. This method is used successfully to discover two computers on the network of Southern Illinois University which were infected with malicious feral software, as well as two more IP addresses on the university network with other security problems.

A Lesson On Homophobia And Teasing, Eva S. Goldfarb

Department of Public Health Scholarship and Creative Works

Homophobia and gay-related teasing are already present among young children. This lesson introduces the term “prejudice” and places the concept of homophobia within the context of bullying and teasing with which 8–11 year olds are already familiar. The lesson builds empathy as children think about and discuss how they have felt when they have been teased or called a name and how they think people in gay or lesbian families would feel. The lesson celebrates the lives of gay and lesbian people as it celebrates diversity among all people and families. Children are encouraged to think about the diversity within …

An Optimal Principle In Fluid-Structure Interaction, Bong Jae Chung, Ashuwin Vaidya

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

We study the steady terminal orientation of a fore-aft symmetric body as it settles in a viscous fluid. An optimal principle for the settling behavior is discussed based upon entropy production in the system, both in the Stokes limit and the case of near equilibrium states when inertial effects emerge. We show that in the Stokes limit, the entropy production in the system is zero allowing any possible terminal orientation while in the presence of inertia, the particle assumes a horizontal position which coincides with the state of maximum entropy production. Our results are seen to agree well with experimental …

What's Fair Is Fair? Role Of Justice In Family Labor Allocation Decisions, Constance Gager

Department of Family Science and Human Development Scholarship and Creative Works

The theoretical basis on which wives and husbands in the United States evaluate the fairness of the division of household labor is explored. Based on distributive justice theory, separate interviews with wives and husbands are conducted to identify and define the household inputs or contributions that are valued as well as the underlying justice principles that guide household labor allocations. The findings suggest considerable variation in the value placed on household chores and the underlying justice principles used when allocating housework. Gendered expectations also play an important role in these allocations.

The Percentage Of Beds Designated For Medicaid In American Nursing Homes And Nurse Staffing Ratios, Christopher Donoghue

Department of Sociology Faculty Scholarship and Creative Works

Previous analyses of the inverse relationship between a nursing home's Medicaid census and its quality of care have been based on samples limited to specific geographic regions, for-profit entities, or only skilled care facilities. The present study uses national-level data from the 1999 National Nursing Home Survey to examine the association between the proportion of beds designated for Medicaid residents and nurse staffing ratios. The results indicate that homes which designate a higher proportion of their beds for Medicaid recipients maintain lower ratios of registered nurses and nurse's aides to residents, even when key facility characteristics are controlled. It was …

Breast And Cervical Cancer Screening Practices Among Disabled Women Aged 40–75: Does Quality Of The Experience Matter?, Sze Yan Liu, Melissa A. Clark

Department of Public Health Scholarship and Creative Works

Background

Women with disabilities (WWD) face significant barriers accessing healthcare, which may affect rates of routine preventive services. We examined the relationship between disability status and routine breast and cervical cancer screening among middle-aged and older unmarried women and the differences in reported quality of the screening experience.

Methods

Data were from a 2003–2005 cross-sectional survey of 630 unmarried women in Rhode Island, 40–75 years of age, stratified by marital status (previously vs. never married) and partner gender (women who partner with men exclusively [WPM] vs. women who partner with women exclusively or with both women and men [WPW]).

Explaining The Race Difference In Prostate Cancer Stage At Diagnosis, Beth A. Jones, Wen-Liang Liu, Andre B. Araujo, Stanislav V. Kasl, Stephanie A. Navarro Silvera, Hosanna Soler-Vila, Mary G.M. Curnen, Robert Dubrow

Department of Public Health Scholarship and Creative Works

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 …

Topological Dynamics Of Two-Piece Eventually Expanding Maps, Youngna Choi

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

In this work we show that two-piece eventually expanding maps have the same topological dynamics as two-piece expanding maps. A two-piece eventually expanding map possesses an invariant set that is either a topological attractor or can be perturbed to become one.

Hydrological Impact Of The Potential Future Vegetation Response To Climate Changes Projected By 8 Gcms, Clement Alo, Guiling Wang

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

This study uses offline simulations with a land surface model to explore how the future response of potential vegetation to elevated CO2 and attendant climate changes feeds back to influence surface hydrological processes. Climate changes are those projected by eight General Circulation Models (GCMs) under the SRESAlB, and the potential natural vegetation structure corresponding to the Preindustrial control and SRESAlB 2100 climate of the 8 GCMs are simulated by a dynamic global vegetation model integrated to equilibrium. For climate change forcing from each GCM, comparisons are made among three surface hydrology simulations using CLM3.0 driven with different combinations of climate …

Roller Coaster Marathon: Being A Live Liver Donor, Charlotte C. Cabello, Janice Smolowitz

School of Nursing Faculty Scholarship and Creative Works

The purpose of this phenomenological study was to examine the meaning of being a live liver donor. Six people between ages 27 and 53 years participated. A qualitative, in-depth, semistructured interview format was used to explore donors' thoughts and feelings about being an organ donor. Five themes were identified: (1) no turning back-how do I live without you? (2) roller coaster marathon, (3) donor network, (4) the scar, and (5) reflections-time to think. At the center of the experience was the donor's commitment to the recipient. Once donors began the process, they were determined to see it through. The process …

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 …

Verification And Implementation Of Language-Based Deception Indicators In Civil And Criminal Narratives, Joan Bachenko, Eileen Fitzpatrick, Michael Schonwetter

Department of Linguistics Faculty Scholarship and Creative Works

Our goal is to use natural language processing to identify deceptive and non-deceptive passages in transcribed narratives. We begin by motivating an analysis of language-based deception that relies on specific linguistic indicators to discover deceptive statements. The indicator tags are assigned to a document using a mix of automated and manual methods. Once the tags are assigned, an interpreter automatically discriminates between deceptive and truthful statements based on tag densities. The texts used in our study come entirely from "real world" sources-criminal statements, police interrogations and legal testimony. The corpus was hand-tagged for the truth value of all propositions that …

Recently Arrested Adolescents Are At High Risk For Sexually Transmitted Diseases, Christopher Salvatore, Steven Belenko, Richard Dembo, Doris Weiland, Matthew Rollie, Alexandra Hanlon, Kristina Childs

Department of Justice Studies Faculty Scholarship and Creative Works

Adolescent offenders may be at high risk for sexually transmitted diseases (STDs). With previous research and interventions focused on incarcerated adolescents, data are needed on STD prevalence and risk factors among newly arrested youth released to the community, a far larger subgroup.Participants were recruited from all arrested youth processed at the Hillsborough County, Florida Juvenile Assessment Center during the last half of 2006 (506 males, 442 females). Participants voluntarily providing urine samples for drug testing as part of standard protocol were also consented to having their specimens split and tested for chlamydia and gonorrhea, using an FDA-approved nucleic acid amplification …

Marginalized By Race And Place: Occupational Sex Segregation In Post-Apartheid South Africa, Sangeeta Parashar

Department of Sociology Faculty Scholarship and Creative Works

Racial and gender disparities found in most other societies are particularly magnified in South Africa where the marginalized social group constitutes a numerical majority of the population. These factors, along with region, are dominant axes of inequality in the country. However, empirical knowledge of the interplay between these systems of social inequality in determining employment outcomes remains somewhat scant. This dissertation addresses that gap by studying occupational sex segregation across various racial groups using multilevel modeling techniques. Individual-level data from the 2001 Census and magisterial-level data from survey data aggregations and published sources are used. I first study the influence …

Marginalized By Race And Place: Occupational Sex Segregation In Post-Apartheid South Africa, Sangeeta Parashar

Department of Sociology Faculty Scholarship and Creative Works

Purpose: Given South Africa’s apartheid history, studies have primarily focused on racial discrimination in employment outcomes, with lesser attention paid to gender and context. This paper fills an important gap by examining the combined effect of macro-and micro-level factors on occupational sex segregation in post-apartheid South Africa. Intersections by race are also explored. Design/methodology/approach A multilevel multinomial logistic regression is used to examine the influence of various supply and demand variables on women’s placement in white- and blue-collar male-dominated occupations. Data from the 2001 Census and other published sources are used, with women nested in magisterial districts. Findings Demand-side results …

Agency: The Internal Split Of Structure, Yong Wang

Department of Sociology Faculty Scholarship and Creative Works

In this article I first examine the ways in which the dual terms of structure and agency are used in sociological theories. Then, relying on Lacan’s notions of split‐subject, the formula of sexuation, and forms of discourses, and Laclau’s theory of ideological hegemony, I argue that agency in most current sociological formulations is but a posited other of the structure that dissolves if examined closely; it is similar to the Lacanian fantasmic object. To resolve the fundamental paradoxes in structure‐agency theories, I reformulate structures as paradoxical, incomplete, and contingent symbolic formations that are always partial and unstable due to their …

Validation Of A Short Questionnaire To Assess Mothers’ Perception Of Workplace Breastfeeding Support, Yeon Bai, C-Y Joanne Peng, Alyce D. Fly

Department of Nutrition and Food Studies Scholarship and Creative Works

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 …

Economic Reforms, Fdi, And Economic Growth In India Sector Level Analysis, Chandana Chakraborty, Peter Nunnenkamp

Department of Economics Faculty Scholarship and Creative Works

Booming foreign direct investment (FDI) in post-reform India is widely believed to promote economic growth. We assess this proposition by subjecting industry-specific FDI and output data to Granger causality tests within a panel cointegration framework. It turns out that the growth effects of FDI vary widely across sectors. FDI stocks and output are mutually reinforcing in the manufacturing sector, whereas any causal relationship is absent in the primary sector. Most strikingly, we find only transitory effects of FDI on output in the services sector. However, FDI in the services sector appears to have promoted growth in the manufacturing sector through …

Existence Of Multiple-Stable Equilibria For A Multi-Drug-Resistant Model Of Mycobacterium Tuberculosis, Abba B. Gumel, Baojun Song

Department of Applied Mathematics and Statistics Faculty Scholarship and Creative Works

The resurgence of multi-drug-resistant tuberculosis in some parts of Europe and North America calls for a mathematical study to assess the impact of the emergence and spread of such strain on the global effort to effectively control the burden of tuberculosis. This paper presents a deterministic compartmental model for the transmission dynamics of two strains of tuberculosis, a drug-sensitive (wild) one and a multi-drug-resistant strain. The model allows for the assessment of the treatment of people infected with the wild strain. The qualitative analysis of the model reveals the following. The model has a disease-free equilibrium, which is locally asymptotically …

Astrophysically Triggered Searches For Gravitational Waves: Status And Prospects, B. Abbott, R. Abbott, R. Adhikari, P. Ajith, B. Allen, G. Allen, R. Amin, S. B. Anderson, W. G. Anderson, M. A. Arain, M. Araya, H. Armandula, P. Armor, Y. Aso, S. Aston, P. Aufmuth, Rodica Martin

Department of Physics and Astronomy Faculty Scholarship and Creative Works

In gravitational-wave detection, special emphasis is put onto searches that focus on cosmic events detected by other types of astrophysical observatories. The astrophysical triggers, e.g. from γ-ray and x-ray satellites, optical telescopes and neutrino observatories, provide a trigger time for analyzing gravitational-wave data coincident with the event. In certain cases the expected frequency range, source energetics, directional and progenitor information are also available. Beyond allowing the recognition of gravitational waveforms with amplitudes closer to the noise floor of the detector, these triggered searches should also lead to rich science results even before the onset of Advanced LIGO. In this paper …

Using Van Valens Procedure In Business Research To Assess Consistent Differences In Multidimensional Variability In Two Or More Groups, Mark L. Berenson, Kimberly Killmer Hollister

Department of Information Management and Business Analytics Faculty Scholarship and Creative Works

Much business research involves comparisons in two or more groups on many dimensions. This paper primarily focuses on demonstrating and providing guidance as to how researchers should approach a multivariate analysis in the comparison of sets of corresponding characteristics in two or more independent groups. In particular, this paper demonstrates the utility of a simple but not widely known procedure developed by Van Valen (1978) that should be employed to test for the significance of differences in overall variability in the sets of corresponding characteristics in two or more groups, a test that enjoys much statistical power in detecting significant …

Annotating An Arabic Learner Corpus For Error, Ghazi Abuhakema, Reem Faraj, Anna Feldman, Eileen Fitzpatrick

Department of Linguistics Faculty Scholarship and Creative Works

This paper describes an ongoing project in which we are collecting a learner corpus of Arabic, developing a tagset for error annotation and performing Computer-aided Error Analysis (CEA) on the data. We adapted the French Interlanguage Database FRIDA tagset (Granger, 2003a) to the data. We chose FRIDA in order to follow a known standard and to see whether the changes needed to move from a French to an Arabic tagset would give us a measure of the distance between the two languages with respect to learner difficulty. The current collection of texts, which is constantly growing, contains intermediate and advanced-level …
