Co-Occurrence Patterns Of Common And Rare Leaf-Litter Frogs, Epiphytic Ferns And Dung Beetles Across A Gradient Of Human Disturbance, Johan A. Oldekop, Anthony J. Bebbington, Nathan K. Truelove, Niklas Tysklind, Santiago Villamarín, Richard F. Preziosi

Geography

Indicator taxa are commonly used to identify priority areas for conservation or to measure biological responses to environmental change. Despite their widespread use, there is no general consensus about the ability of indicator taxa to predict wider trends in biodiversity. Many studies have focused on large-scale patterns of species co-occurrence to identify areas of high biodiversity, threat or endemism, but there is much less information about patterns of species co-occurrence at local scales. In this study, we assess fine-scale co-occurrence patterns of three indicator taxa (epiphytic ferns, leaf litter frogs and dung beetles) across a remotely sensed gradient of human …

Low-Voltage Closed Loop Mems Actuators, Shahrzad Towfighian, Glenn Heppler, Eihab Abdel-Rahman

Mechanical Engineering Faculty Scholarship

An efficient electrostatic resonator is designed by adding a low voltage controller to an electrostatic actuator. The closedloop actuator shows stable, and bi-sable behaviors with bounded chaotic oscillations as large as 117% of the capacitor gap. The controller voltage is decreased from a previously designed resonator to less than 9 V thereby reducing the load on the controller circuit components. Bifurcation diagrams are obtained showing the frequency and magnitude of AC voltage required for chaotic oscillations to develop. The information entropy, a measure of chaotic characteristic, is calculated for the micro-resonator and is found to be 0.732.

Everyday Discrimination And Life Space In Older African American Adults, Quiana Joyce Lewis

Public Health Theses

The current study seeks to explore the association between self-reported experiences of discrimination and life space. Life space is a multidimensional construct that measures the spatial area for which a person intentionally interacts on a daily basis. We explored the cross-sectional association between self-reported experiences of discrimination and life space in a sample of 350 African American older adults recruited between August 2004 and January 2010 from various community-based organizations, churches, and senior facilities within the greater Chicago, IL area. The study participants reported low amounts of discrimination and large life spaces (approximately two-thirds of the population ventured outside of …

Stereotypes On Aging And Effects On The Health Of Older Adult Couples, Frank Lin

Public Health Theses

Negative stereotypes of aging are widespread in American culture and have been shown to have detrimental effects on the health of older individuals. Little has been done to examine the dynamics of views on aging in older adult relationships. We aim to examine the stereotypes of aging held by older married couples in which one individual has a musculoskeletal condition. Specifically we're interested in seeing if an individual's stereotypes of aging affect (1) their own physical and psychological, and relationship health (2) their partner's physical, psychological, and relationship health and (3) whether there are interaction effects of aging attitudes in …

La Lógica Curativa Maya Kaqchikel: Oración, Fármaco Y Supervivencia Cultural, Servando Z. Hinojosa

Anthropology Faculty Publications

Dada la creciente presencia de recursos médicos occidentales en el altiplano guatemalteco, se observa que practicantes de la medicina tradicional maya han llegado a conocer y a manejar una importante cantidad de fármacos y otros productos de patente. Esta utilización se ha llevado a cabo dentro de un esquema terapéutico fisiológico que a la vez reconoce la frecuente apariencia de casos de males de naturaleza espiritual como son el susto, el mal de ojo y la brujería. Esta situación se vuelve más compleja puesto que el sistema nacional de salud privilegia los conceptos occidentales y urbanos de la salud y …

Feasibility Study Of Trans-Cranial Direct Current Stimulation In Presence Of Brain Tumor, Abhilash Nair

Dissertations and Theses

Trans-cranial Direct Current Stimulation has been shown to modulate cortical neuronal activity. Weak constant current is applied to the scalp using electrodes, leading to sub-threshold changes in neuronal membrane potential. Before actual clinical stimulation is performed, such systems are validated by simulating the stimulation and the resulting current flow patterns using finite element solvers. However, the reliability of such models depends upon the accuracy with which the underlying anatomy has been modeled [1]. In earlier studies it has been shown that the current flow patterns within the brain are altered due to the presence of lesioned brain tissues[2]. Here we …

National Sovereignty V Regionalism; Toward A Common Fisheries Policy For Caricom, Andrea Chambers

Dissertations and Theses

The hypothesis which guides this thesis is that successful integration cannot be achieved so long as member states of a regional grouping are unwilling to subordinate the individual interest to the collective interest. The Caribbean Community (CARICOM) – which is the second oldest regional institution in the Western Hemisphere – is the central focus of the work. In order to assess this hypothesis, the study first discusses the relevant integration literature, and then addresses the issue of individual vs. collective interests in CARICOM overall. Next it examines the specific functional area of fisheries which effectively illustrates the complexity of this …

Female Leaders And Women's Empowerment; 3 Case Studies, Nicole Dimarco

Dissertations and Theses

"The issue of women’s empowerment and gender equality is a global issue and one that, in many parts of the world, is in dire need of attention. It is for this reason I have decided to examine whether women in positions of power facilitate the enactment of gender-oriented measures or whether they continue to focus on the traditional national security interests, or interests of another kind, of their countries. My hypothesis is that women in power are not significantly more likely than men to pursue gender-specific policies while in office. Instead, much depends on environmental factors and individual personality. Sometimes …

The United Nations And Gender-Mainstreaming; International Conferences On Women And The Development Of Gender Mainstreaming Policies In Caribbean States, Camasita Campo

Dissertations and Theses

"International conferences, especially UN-sponsored summits, are popular venues for political coalition around various issues of global concerns, mobilizing large audiences consisting of state representatives, NGO groups and other interested parties. Many small states participate at leading international summits. Some of these states for many obvious reasons are preoccupied with economic survival. Their limited resources are expended on economic priorities and little or none is left for the implementation of social development programs. As a result, these small states are constrained from defining contours of social development, without the cooperation of the international community. They must therefore depend on external actors …

The Rising Threat Of Food Security; A Keynesian Solution To A Global Problem, Auour Heoinsdottir

Dissertations and Theses

"Is food security a threat to Global security? Recent history suggests so. After all, since 1947 the international community has struggled to implement agreements on agriculture in the name of preserving peace. Most recently, in the last of the Doha Development Round negotiations, efforts have been made to enhance food security (with measures such as equal access to resources, trade liberation, and the removal of tariffs for developing countries). In my thesis I will explore both the theory of these policies and their efficacy in practice. More specifically, I will examine the limitations of past policies (such as ""anti-dumping"") aimed …

The One State Solution An Alternative Vision For Ending The Israeli-Palestinian Conflict, Abdul Yousef

Dissertations and Theses

"The debate for a two state solution for the Israeli-Palestinian conflict has been ongoing for decades. However, given the current circumstances and realities on the ground, this approach has become more implausible with each passing day. Therefore, many have come to argue the real solutionwould be a single state that would afford equal rights for both Israeli and Palestinian citizens regardless of ethnicity, religion, or racial background. Considering the troubled history of the region, many would view a state where Israelis and Palestinians living together, sharing land, and engaged in a peaceful democratic process to be an unattainable fantasy. This …

The Role Of Sleep In The Enhancement And Impedance Of Episodic Emotional Memories, Rafael De Jesus

Dissertations and Theses

"The current study examined whether sleep enhances the retention of emotionally arousing memories, and whether an emotional memory can be blocked with a single night of sleep deprivation. Using a modified version of a slide show varying in emotionality with respect to the narrative (participants' acting as either a mother or father experiencing the tragic death of their imagined child), 100 (healthy young adult student volunteer) subjects following the experience were randomly assigned to either a normal night of sleep or were variously sleep deprived (in laboratory). After having experienced the emotional event followed immediately by a night of sleep …

Self-Concept Related To Identities And Safer-Sex Cognitions In Young Adults Who Have Lost A Parent To Aids, Marcie Berman

Dissertations and Theses

In-person interviews conducted with 40 English-speaking AIDS-bereaved 18-22 year olds and a control group revealed a significant difference in identities. Data were collected from an AIDS-bereaved group through Rutgers, the State University of New Jersey and an introductory psychology class at Hunter College, City University of New York. Hierarchical Classes (HICLAS; Ceulemans & Van Mechelen, 2005) data analysis uncovered a significant difference in how the groups elaborate their current and ideal selves and their self-cognitions surrounding protected and unprotected sex with both new and ongoing partners. Chi-square analysis showed significant differences in elaboration levels regarding how the AIDS-bereaved viewed unprotected …

Reducing False Positive Feigning Classifications On The Sirs Among Criminal Defendants With A History Of Trauma, Lea Corconan

Dissertations and Theses

Clinical research has demonstrated that individuals with a traumatic history elevate scales on the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) leading to their misclassification as malingerers. Rogers, Payne, Correa, Gillard, and Ross (2009) created the trauma index (TI) by summing 3 SIRS scales to reduce the number of false positives in a severely traumatized sample. The TI was included as an additional criterion in determining feigning. The TI has not been studied using a forensic sample. Fifty-one adult male criminal defendants were identified as malingering by the SIRS with a final sample of 5 definite …

Sensation Seeking, Early Pregnancy And Criminal Justice System Involvement Among Latino Youth, Jillian Jankie

Dissertations and Theses

The present study examined the relationship between the level of sensation seeking, early pregnancy, and criminal justice system involvement among Latino youth. It is a secondary analysis of data that comes from the Boricua Youth Study, an ongoing longitudinal study of Puerto Rican children and preadolescents living in the South Bronx and Puerto Rico. In the current analysis, data were analyzed on 69 participants who had completed measures of sensation seeking, pregnancy and arrests to predict whether sensation seeking would predict arrests and pregnancy at the second time period. Sensation seeking was evaluated at baseline. Early pregnancy and criminal justice …

Perceived Discrimination And Depression As It Relates To Nativity Status Of Students From Immigrant Backgrounds, Melissa Huey

Dissertations and Theses

"Research has found that foreign born immigrants' have better mental and physical health, as well as higher levels of academic achievement, than native born individuals from immigrant families (Vega, et. al., 2004). There is some evidence that perceived discrimination could be a possible explanation for these nativity differences (Juang & Cookston, 2009). The current study tested the hypothesis that native born individuals from immigrant backgrounds will have higher levels of depression than their foreign born counterparts and that native born respondents will report higher levels of perceived discrimination than foreign born. The study also tested whether perceived discrimination mediates the …

Interaction Of Long- And Short-Term Memory On Selective Attention During Timbre Discrimination, Eva Garcia

Dissertations and Theses

The present study investigated the effects of short- and long-term memory on processes of selective attention during timbre discrimination. Pitch served as the distractor dimension, held constant on standard trials and deviating from the standard frequency on distractor trials. Short-term memory was operationalized as levels of covariate context: Within a block of trials, pitch deviants (p=.28) were either absent (baseline condition), varied orthogonally (filtering condition) or systematically (positive and perfect conditions) with timbre values. Long-term memory was operationalized as levels of psychophysical context: Within a block of trials, the range of pitch change was psychophysically equated with timbre change in …

The Effects Of Circadian Rhythm-Related Mood On Recognition And Recall Memory For Emotional Images, Priya Puliyampet

Dissertations and Theses

"Studies have proposed that sleep following the presentation of emotional information aids in the consolidation of memory for the emotional elements of the stimuli. Some of these studies have used a paradigm that may have been affected by the confounding influence of circadian factors. Mood may follow a circadian rhythm and research suggests that mood at the time of recall can influence the content of the memory recalled. This study was meant to determine whether the enhanced memory for emotional stimuli in the morning following a night of sleep is a function of the circadian rhythm of mood. Better recall …

The Influence Of Positive Affect And Anxiety On Attention And Creativity, Rafal Skiba

Dissertations and Theses

The study examined naturally occurring effects of positive affect and anxiety (exam stress at different points in the semester) on attentional performance and creative abilities of undergraduate students. The mood of participants was measured by PANAS and STAI questionnaires. Their attention was tested on the Eriksen Flanker Task, and creativity on the Remote Associates Test (RAT) and Compound Word Problems (CWP). One of the main goals of this study was to verify the prediction based on the Broaden and Build theory of positive resources by Fredrickson (2001). Although the mood manipulation used in this study, that is, placing both testing …
