A Match Or A Mismatch: Comparing College Stated Learning Goals To Student Learning Goals And Perception Of Educational Quality
Stander Symposium Projects
An institution’s ability to meet students’ learning expectations influences student perceptions of educational quality and usefulness. Currently, colleges and universities are trying to provide evidence of these attributes through various summative assessment instruments. However, the content and structure of most assessment instruments measures what students have retained, not actual cognitive change or instances of goal achievement. This study surveyed a random sample of students at a four-year liberal arts college asking them to describe their personal learning goals and quantify the quality and usefulness of the education they received. The students’ goals were then compared to the stated goals of …
Firm Characteristics, Concentrated Portfolio Strategies And Industrial Sector Price Movements In 2014
Stander Symposium Projects
This study is part of a series of studies in the Davis Center for Portfolio Management focused on portfolio weighting. It also considers the alpha generating capabilities of a concentrated portfolio of stocks using relative valuation and momentum stock weighting strategies. The top 10 holdings of the SPDR sector ETF XLI are used as the concentrated portfolio of stocks. Various price-to measures such as price to earnings and price to book are used to develop the weights for each stock in the concentrated portfolio. One year ahead expected earnings growth for each of the 10 stocks provides the basis for …
A Smart Beta Approach To Portfolio Weighting For A Concentrated Portfolio Of Consumer Discretionary Stocks
Stander Symposium Projects
The two major approaches to weighting market indexes are price weighting (DOW) and market cap weighting (S&P 500). In this study, we use a Smart Beta approach by weighting stocks based on their fundamental and earnings growth characteristics. Using price to earnings, price to book, price to sales, and price to cash flow measures plus expected one year earnings growth, we weight the top 10 holdings of the SPDR Consumer Discretionary ETF (XLY) and compare their performance as a portfolio of stocks to XLY, the DOW, and the S&P 500 for the year 2014. Two weighting strategies are used. A …
A Time Series Analysis Of Service Consumption Expenditures As Determinants Of The Consumer Discretionary And Consumer Staples Sector Price Movements, 2004-2014.
Stander Symposium Projects
A growing portion of U.S. Consumer income is spent on services. Both directly and indirectly these expenditures effect the stock market prices of firms in the consumer discretionary and consumer staples sectors. The objective of this study, therefore is to determine if the market prices of these two sectors co-vary with the growth in consumer services expenditures. The period of analysis is 2004-2014. Quarterly pricing and expenditure level data are used in the analysis. Using regression analysis, the hypothesis to be tested is service expenditures and discretionary and staples sector prices co-vary directly with each other. We expect the b …
Extremum Seeking Control Observer Design For Multiple-Input Multiple-Output Linear Time-Invariant Systems
Stander Symposium Projects
In this proposal a control strategy, we try to address the problem of output (performance) function for an observer of Multiple-Input Multiple-Output (MIMO) linear time-invariant system by applying the Extremum Seeking Control (ESC) approach. By this control approach, we drive the performance function to its maximum or minimum value. The construction of a seeking algorithm is used to drive the system states to the desired set-points that maximize or minimize the value of an objective (performance) function. Also, Lyapunov's stability theorem and the perturbation theory including the averaging method is used in the design of the extremum seeking controller structure …
“Optimization Of The Hydro Thermal Liquefaction Process For Increased Yields, And For Both Energy And Cost Efficient Production Of A Cleaner Bio-Crude Suitable For Refineries”
Stander Symposium Projects
Increased use and limited reserves of fossil fuels have increased interest in renewable fuels. Algae biomass has been identified as a viable renewable fuel feedstock for biofuel (green diesel / jet fuel) generation. Hydrothermal liquefaction (HTL) is a promising energy efficient technology for converting wet-algae biomass into energy dense “bio-crude” suitable for use in refineries and recycling nutrients for growing algae. The composition of the bio-crude affects the quality and the process economics involved in converting the bio-crude to commercial fuel. Both the process operating conditions and the algal HTL feedstock composition affect the bio-crude composition. Thus, the proposed effort …

This research shows that it is vital for student affairs professionals to take a closer look at the effect academic advisers have on the student experience.
Multistage Flash Desalination With An Integrated Solar System
Multistage Flash Desalination With An Integrated Solar System
Stander Symposium Projects
Desalination is considered to be a promising solution to overcome the problems of water shortage especially for countries that have dry weather conditions with less rainfall around the year. Thermal processes have the highest capacity among all other desalination processes but it consumes significant amount of fossil fuel which severely affects the environment in diverse aspects. On that end, the importance of using renewable energy source such as solar desalination has increased in the present time. In solar desalination, the energy can be transferred in the form of either thermal energy as used in thermal storage technologies or electrical energy …
Rapidly Locating And Accurately Tracking The Center Of Mass Using Statically Equivalent Serial Chains
Stander Symposium Projects
Identifying the center of mass location (CoM) provides a significant aid in controlling the balance of humanoid robots. For human beings, the stability of motion is highly influenced by their ability to control their CoM and center of pressure (CoP). Additionally, computing the CoM can prove critical to assessing rehabilitation and in elite sports training. Human body segment parameters can be obtained from anthropometric tables. Their accuracy for a given individual is questioned due to differences in age, race, and fitness level from the sample population. This research presents an estimation technique that uses the statically equivalent serial chain (SESC). …
Joint Design And Analysis Of Leakage In Movable Extrusion Dies.
Joint Design And Analysis Of Leakage In Movable Extrusion Dies.
Stander Symposium Projects
This project presents an analysis of various joint types used in variable geometry dies that enable the extrusion of plastic parts with a varying cross section. Extrusion accounts for 40% of all manufactured plastic parts because it is a relatively low-cost and high-production-rate process. Conventional polymer extrusion technology, however, is limited to fixed dies that produce continuous plastic products of constant cross section defined by the die exit profile. A shape changing die allows the cross section of the extruded part to change over its length, thereby introducing the capacity to manufacture plastic faster and with lower tooling costs than …

Recommendations are presented for staff members, IEP instructors, and students to assist in improving the social success …
Integrating Institutional Mission Into Faculty Work
Integrating Institutional Mission Into Faculty Work
Stander Symposium Projects
The integration of a faith-based university’s mission into the curriculum and the requirements that this identity imposes upon faculty members’ scholarship are often at odds with the concept of academic freedom (VanZanten, 2011). This common dilemma is an authentic and significant part of Catholic higher education. To balance a conceptual understanding of faith integration with practical tools for academic professionals looking for resources, the University of Dayton’s Commitment to Community (C2C) document provides a community approach to education (University of Dayton, n.d.). This document could be a valued resource to assist faculty in applying mission-based values into their teaching, research, …

Research Exercise: A Mathematical Model To Calculate An Animals Equilibrium Temperature Based On The Environmental Temperature
Stander Symposium Projects
Every animal’s temperature is directly correlated to the temperature of the environment that the animal lives in. The animal’s equilibrium temperature can be modeled using mathematical tools based on the temperature of the environment, the amount of solar radiation, and the heating characteristics of the specific animal. Newton’s Law of Cooling can be used to model this sort of phenomena of temperature changes. This mathematical model provides a relation between the unknown temperature and the derivative of this unknown temperature. In this work we will solve this model numerically using different techniques such as the Euler method, the three-term Taylor …

Under Pressure? The Relationship Between Reciprocity, Intimacy, And Obligation In Self-Disclosure
Under Pressure? The Relationship Between Reciprocity, Intimacy, And Obligation In Self-Disclosure
Stander Symposium Projects
Studies of self-disclosure conducted in the lab report that individuals report greater liking for those who disclose highly intimate information; whereas field studies report that individuals report greater liking for those who disclose information of lower intimacy. One possible explanation for such inconsistent findings is that laboratory studies typically create a scenario where the recipient of self-disclosed information is expected and obligated to reciprocate. Field studies, however, remove the obligation for the participant to reciprocate, thus creating an unbiased evaluation. Thus far, research has not directly compared the level of intimacy with whether the participant is obligated to respond or …
Mostly True: An Exploration Of My Family History
Mostly True: An Exploration Of My Family History
Stander Symposium Projects
Family histories are tricky things, especially when the people in the stories don't necessarily want to talk about their pasts. My family immigrated to the US in the early 1800's, many to escape the anti-Semitism that was rampant in their countries. Through a series of personal interviews, family stories passed down from generation to generation, and my own imagination to fill in the gaps, I have compiled a series of short stories about my family and their lives in America from their arrival here in the 1800's to the present day. Although each family has a different story to tell, …
Root Cover Pebbling On Graphs
Stander Symposium Projects
A graph is a mathematical object that can be described as a set of vertices and a set of edges. An edge joins one vertex to another. The existence or absence of an edge between two vertices can represent a relationship or absence of a relationship between two objects. Two vertices are said to be adjacent if there is an edge that joins them. Imagine placing pebbles on the vertices of a graph. We can move a pebble from one vertex to an adjacent vertex using certain pebbling moves in which two pebbles are removed from a vertex and one …
The State Of El Salvador: Human Rights And Violence In The Post-War Era
The State Of El Salvador: Human Rights And Violence In The Post-War Era
Stander Symposium Projects
During the Salvadoran Civil War (1979-1992), the government of El Salvador knowingly used forms of political violence such as disappearances and torture against the political opposition and other innocent civilians, including women and children. With the signing of the Peace Accords in 1992, El Salvador has since transitioned from an authoritarian regime to a democracy. This project focuses on how the change in regime type influenced the level of repression and respect for human rights in El Salvador. The research analyzes two conflict resolution mechanisms, the Peace Accords and Truth Commission, and the implementation of democratic practices such as elections …
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 …
Do You See What I See? Perceiving Distances From Another’S Perspective
Do You See What I See? Perceiving Distances From Another’S Perspective
Stander Symposium Projects
The ability to accurately perceive distances between the self and objects/targets underlies action-guidance and spatial navigation. While one can easily and accurately judge distances from his or her own perspective, it is largely unknown whether distance judgments from an imagined perspective are as accurate as from one’s own viewpoint. This study will investigate the accuracy of distance judgments made from another person’s viewpoint. To do so, participants will be asked to either adopt a confederate’s viewpoint or to imagine standing in a different location (without a confederate acting as a stand-in) and to estimate distance from these novel perspectives. As …
The Layered Look: Do Additional Layers Of Clothing Influence Perceived Reach Ability?
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
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 …
Characterization Of The P53 Signaling Pathway In Urodele Amphibians During Lens Regeneration
Characterization Of The P53 Signaling Pathway In Urodele Amphibians During Lens Regeneration
Stander Symposium Projects
Urodele amphibians such as the red spotted newt, Notophthalmus viridescens, and axolotl are commonly used to study organ regeneration due to their remarkable ability to regenerate organs such as limb, tail, spinal cord and lens. The newt is able to regenerate the lens solely from dorsal iris pigmented epithelial cells in 30 days following removal. Axolotls, neonate salamanders, invoke curiosity because they can only regenerate their lens two weeks post hatching although they have the same regeneration potential as newts for limb, tail, and spinal cord. Using these animal models the role of the p53 protein, a tumor suppressor protein, …

Restorative Justice: The Alternative Outlet For Criminal Behavior
Stander Symposium Projects
As members of the University of Dayton Social Justice Club, our group carried out a semester long project focused on Restorative Justice in conjunction with the Montgomery County Mentoring Collaborative. We were assigned to Belmont School and each given a young girl to work with. Each young girl we were paired with had a history with incriminating behavior. Our responsibility included talking with our partner and helping them claim responsibility for their actions. Additionally, we talked through previous decisions and their consequences to encourage the girls to start thinking about the impact of their actions.
