Examining The Role Of Self-Esteem In The Association Between Emotional Vulnerability And Psychological Well-Being. Apr 2015

Examining The Role Of Self-Esteem In The Association Between Emotional Vulnerability And Psychological Well-Being.

Stander Symposium Projects

The purpose of the proposed study was to examine the association between emotional vulnerability and psychological well-being, and test whether the association varies based on level of self-esteem. Researchers define psychological well-being as an appraisal of one’s life where a person gives conscious evaluative judgments about one’s satisfaction with life as a whole (Grossi et al., 2013). Emotional vulnerability is defined as the degree to which a person renders himself or herself exposed to the emotional pain of rejection. Experiencing social rejection has a negative effect on self-esteem, however, having high self-esteem may buffer the self against the pain of …

The Layered Look: Do Additional Layers Of Clothing Influence Perceived Reach Ability? Apr 2015

The Layered Look: Do Additional Layers Of Clothing Influence Perceived Reach Ability?

Stander Symposium Projects

The Layered Look- How Many Sweatshirts Does It Take?Clothing plays a necessary role in exhibition of personal style, concealment of body parts that are deemed unacceptable to exhibit by cultural norms, and protection from adverse weather (Flügel, 1930). But anyone who has worn a heavy parka knows that there is a seeming loss of motion that comes with bulky or layered apparel. Does wearing bulky clothing actually change the way we perceive our bodies and our movement capabilities? Previous studies suggest that tools such as a reaching wand are incorporated into the body schema, the cognitive representation of one’s own …

Changes In Relative Abundance And Spatial Distribution Of Dominant Overstory Taxa In An Old-Growth Forest Over 30 Years Apr 2015

Changes In Relative Abundance And Spatial Distribution Of Dominant Overstory Taxa In An Old-Growth Forest Over 30 Years

Stander Symposium Projects

The temperate deciduous forests of eastern North America are subject to an array of ecosystem drivers including anthropogenic disturbance, gap dynamics, and both local and regional climate events. An ongoing “mesophication” trend has been observed in many of these forests where communities are shifting from oak dominance (Quercus spp.) to more mesophytic, shade-tolerant species (Acer spp.). Using a 30-year dataset (1979–2010) collected in an old-growth forest in southeastern Kentucky, we examined decadal patterns of distribution and relative abundance of dominant overstory taxa: oaks (Quercus spp.), maples (Acer spp.), hickories (Carya spp.), and beech (Fagus grandifolia). Overstory stem data were divided …

Modeling The Relationship Between Non Durable Consumer Expenditures And Stock Market Prices: An Empirical Analysis For The Period 2004-2014 Apr 2015

Modeling The Relationship Between Non Durable Consumer Expenditures And Stock Market Prices: An Empirical Analysis For The Period 2004-2014

Stander Symposium Projects

BEA consumer expenditure data is divided into three components:(1) durable, (2) non durable, and (3)service expenditures. In this study we examine the relationship between non durable consumer expenditures and consumer discretionary and consumer staples sector price movements. Rational expectations theory suggests that increasing demand for non durable goods increases the sales and earnings of the firms operating in both of the above sectors. In turn, this results in rising sector prices. Using linear and log linear regression we test the hypothesis that the regression coefficients are positive and statistically significant. Quarterly data is used in the study with the time …

A Covariance Analysis Of Consumer Healthcare Expenditures And Healthcare Sector Price Movements Apr 2015

A Covariance Analysis Of Consumer Healthcare Expenditures And Healthcare Sector Price Movements

Stander Symposium Projects

In recent years, an increasing portion of consumer expenditures on services is allocated to healthcare. The aging of the U.S. population, the Affordable Healthcare Act, and the rising per unit costs of hospital trips all have influenced this trend. In this study, we test the hypothesis that healthcare sector prices covary directly with consumer expenditures on healthcare services. Using regression analysis, we regress 5 Healthcare sector ETF's on Healthcare consumption expenditures. The ETF's are: (1) Healthcare Sector ETF (XLV), (2) Healthcare Equipment ETF (XHE), (3) Biotech ETF (XBI), (4) Pharmaceuticals ETF (XHP), and (5) Healthcare Services ETF (XHS). Quarterly data …

Tempestites Of The Entrada Sandstone: Mapping And Reservoir Characterization, Jeffery Valenza, Dr. Tom Morris Apr 2015

Tempestites Of The Entrada Sandstone: Mapping And Reservoir Characterization, Jeffery Valenza, Dr. Tom Morris

Journal of Undergraduate Research

Tempestites are sedimentary deposits traditionally thought to be formed by high-energy storm events. Typically, water depth for tempestites has been interpreted to be between fair weather and storm wave base. Tempestites are primarily identified in the rock record by hummocky cross-stratification (HCS). HCS is a typical indicator of oscillatory flow in subaqueous settings, where strong wave action can scour and redeposit sediment. Tempestites may also contain sole marks and various forms of ripples. Some work has been done on tempestites in lower shoreface and carbonate ramp settings, but little research has been done on tempestites in very shallow water to …

Auditory Information In The Form Of A Scratching Sound Enhances The Effects Of The Rubber Hand Illusion Apr 2015

Auditory Information In The Form Of A Scratching Sound Enhances The Effects Of The Rubber Hand Illusion

Stander Symposium Projects

The body schema is generated from a number of different sense modalities such as vision and proprioception. Botvinick and Cohen's rubber hand illusion (1998) demonstrates the relative contributions of vision, tactile perception and proprioception to body awareness. In this illusion, a participant's real hand is concealed from view and a prosthetic rubber hand is seen in its place. An experimenter simultaneously administers tactile stimulation to both the seen rubber hand and participant's actual hidden hand. The combination of this visual and tactile information overrides proprioceptive cues to body perception, creating a sense of ownership of the rubber hand. The present …

Synthesizing Coupler-Drivers As A Novel Method For Actuating Mechanical Systems Apr 2015

Synthesizing Coupler-Drivers As A Novel Method For Actuating Mechanical Systems

Stander Symposium Projects

Abstract:The objective of the proposed work is to change the mechanical design of an automated manufacturing or assembly process by introducing coupler drivers. Currently, the design of a mechanism to be included in a manufacturing or assembly process requires one of the joints in the mechanism to be used for actuation. That is, the desired motion of the device and how it will be moved are coupled and this complicates its design. The proposed work looks at decoupling the kinematic synthesis of a mechanical system from the actuation synthesis of the system. This is accomplished via a mechanical chain called …

Perfectionism, Religious Orientation, And Self-Forgiveness: Mediating And Moderating Factors Apr 2015

Perfectionism, Religious Orientation, And Self-Forgiveness: Mediating And Moderating Factors

Stander Symposium Projects

The relationships between interpersonal forgiveness, perfectionism, and religious orientation have been previously studied (e.g., Ashby & Huffman, 1999; Dixon, Earl, Lutz-Zois, Goodnight, & Peatee, 2014; Meek, Albright, & McMinn, 1995; Steffen, 2013). However, the present study examines how different types of forgiveness, self-forgiveness and perceived forgiveness from God, are related to perfectionism and religious orientation. Previous research indicates that self-evaluative perfectionism, the more maladaptive type of perfectionism (Hill et al., 2004), is negatively associated with intrinsic religious orientation (Ashby & Huffman, 1999). Those with an intrinsic orientation, who profess faith as central to their identity (Allport & Ross, 1967), are …

The Influence Of Music On Psychological Power Apr 2015

The Influence Of Music On Psychological Power

Stander Symposium Projects

Music is commonly believed to give people a sense of power. The current research explored the notion of how music changes two aspects of psychological power: a person’s abstract thinking and sense of control. Past research has indicated that the frequency and the psychological power of the songs can evoke power in the participants. It is believed that music with lower frequencies should make participants feel more powerful than participants who listened to high frequency music. While listening to music participants completed a variety of tasks that look to single out aspects of power. Participants listened to either high or …

Mid-Holocene Speleothem Climate Proxy Records From Florida And Belize, Anna L. Pollock

USF Tampa Graduate Theses and Dissertations

As global temperatures rise due to anthropogenic climate change, water resources, thus economies, are threatened. A geologically recent period of increased temperatures is the mid-Holocene and an investigation of its climate may allow for a better understanding of future precipitation and changes to regional water resources. The regions of interest are tropical Northern Central America and subtropical North America with Belize and Florida representing each climate zone. By reconstructing mid-Holocene climate in Florida and Belize, I hope to provide a better understanding of how increased temperatures and a reduced latitudinal temperature gradient impacts both precipitation patterns and variability. Today, drivers …

Tlv: Abstraction Through Testing, Learning, And Validation, Jun Sun, Hao Xiao, Yang Liu, Shang-Wei Lin, Shengchao Qin

Research Collection School Of Computing and Information Systems

A (Java) class provides a service to its clients (i.e., programs which use the class). The service must satisfy certain specifications. Different specifications might be expected at different levels of abstraction depending on the client's objective. In order to effectively contrast the class against its specifications, whether manually or automatically, one essential step is to automatically construct an abstraction of the given class at a proper level of abstraction. The abstraction should be correct (i.e., over-approximating) and accurate (i.e., with few spurious traces). We present an automatic approach, which combines testing, learning, and validation, to constructing an abstraction. Our approach …

Primes And Zeros: A Million Dollar Mystery, Brian Conrey Apr 2015

Primes And Zeros: A Million Dollar Mystery, Brian Conrey

Dalrymple Lecture Series

A prime number is an integer greater than one whose only positive divisors are 1 and itself. In 1859 G. F. B. Riemann proposed a way to understand how the prime numbers are distributed among the natural numbers. More than 150 years later mathematicians still have not proven Riemann's Hypothesis. The stature of this problem has continued to rise so that today it is widely regarded as the most important unsolved problem in all of mathematics. In this talk I will describe some of the colorful history that surrounds this question.
