Testing The Relationship Between Body Dysmorphic Disorder And Pathological Skin Picking Using A Bidimensional Model Of ‘Fear’ And ‘Anger', Nicole Christine Egan

Dissertations and Theses @ UNI

Body image concerns are pervasive throughout Western culture, but there is a subset of the population who become so preoccupied with specific aspects of their appearance that it leads to clinically significant distress and impairment in their daily lives. This study examined symptoms of two disorders dealing with body concerns: Body Dysmorphic Disorder (BDD) and Pathological Skin Picking (PSP). The primary purpose of this study was to use the bidimensional model of 'fear' and 'anger' (Lara et al., 2006) to test the relationship between BOD & PSP. The model suggests that BDD and PSP are both characterized by high 'anger' …

Faculty Hiring Committees Perceptions Of Hiring Processes And Subjectivity, Laura Caraleen Foster

Dissertations and Theses @ UNI

Hiring the most capable applicants has a large impact on the bottom line of an organization. The most effective tools to identify talent are well known to IndustrialOrganizational Psychologists, but these analytical tools are used less frequently than less effective intuitive procedures, such as the traditional unstructured job interview. In a survey of university faculty, we found that the most important factor influencing the use of a selection tool was its perceived validity, but these perceptions were not wellcalibrated to actual criterion related validity. We found some evidence that perceived validity was influenced by implicit beliefs about hiring. A body …

Leisure: Definitions, Patterns, And Constraints: A Study Of University Students In China, Shisi Zhou

Dissertations and Theses @ UNI

China has witnessed tremendous social transformation in the last three decades due to the introduction of the "open door" policy and economic reforms in the late 1970s, which has resulted in great changes in Chinese culture and identity considerations.

Psychological Predictors Of Athletic Injury, Sarah Marie Ulrich

Dissertations and Theses @ UNI

To date, research has yet to explore differences in injury based on Fear of Failure (FOF). Therefore, the purpose of this study was to determine if: (a) athletes of varying fear of failure profiles have different perceptions of stress, (b) athletes of varying types of fear of failure differ in regards to injury onset, frequency and severity, and ( c) fear of failure predicts injury occurrence and severity. A total of 127 male collegiate athletes competing in football, wrestling, basketball, and track and field participated in this study. Participants completed the Performance Failure Appraisal Inventory (PF AI) to assess fear …

The Moderating Effects Of Family Supportive Organizational Perceptions And Family Friendly Benefits On The Work-Family Interface, Kristen Jones

Dissertations and Theses @ UNI

This study uses the demands-resources model as the theoretical framework for investigating the effect of work hours, work at home, and job demands on the work-family interface. Additionally, potential resources provided by the organization were evaluated as moderators. A questionnaire was administered to full-time workers with at least one dependent child at home. The moderators investigated included family supportive organizational perceptions, family friendly benefits, and flexible work arrangements, were evaluated. The criteria were work-family conflict, family-work conflict and work-family balance. Based on the regression analyses, family supportive organizational perceptions moderated the relationship between job demands and work-family conflict, and flexible …

From The Barrio To A Four-Year University: The Academic Success Stories Of Fifteen Socioeconomic Disadvantaged Latino Male College Students, Erineo Eddy Espinoza

Dissertations and Theses @ UNI

Review of the prior literature on the topic of academic achievement among U.S. Latino students reveals both problematic performance and systematic disadvantaged obstacles that impede their ability to achieve expected academic accomplishments. Despite such conditions, however, there are Latino students from disadvantaged backgrounds who graduated from high school and enrolled in a four year university. Interpretations of action theory were used as a theoretical framework to interview 15 collegiate Latino males, who grew up in disadvantaged socioeconomic communities (barrios) and enrolled in a four year university. Three findings emerged from their interviews that explained the academic achievements from both these …

A Late-Quaternary Record Of Environmental Variability From Lake Sediment Cores, Wind River Range, Wyoming, Tyler Johnson

Dissertations and Theses @ UNI

Sediment cores from two alpine lakes in Wyoming's Wind River Range were collected and analyzed to establish a record of depositional and mineralogical variability. Due to the hydrologic setting and isolation of Fiddlers and Louis lakes, these cores yielded the longest continuous limnological record in the region that extends back nearly 20,000 years to full-glacial conditions, a rarity for alpine lakes in the western United States.

To develop a paleolimnological record for Fiddlers and Louis lakes, the sediment cores were analyzed using four laboratory techniques. These techniques included particle size analysis, x-ray diffraction, heavy mineral analysis, and loss-on-ignition. Radiocarbon ages …

Understanding Environmental Health Disparities Of Roma Populations In Romania, Jennifer L. Hall

Dissertations and Theses @ UNI

The Roma are the largest and most marginalized minority group of Central and Eastern Europe (CEE) with the highest number residing in Romania. Their problems and struggles are multi-faceted and deeply rooted in a long history of discrimination and stigmatization. Over the years, many strategies have been developed and implemented across CEE, yet very few studies have addressed their environmental and occupational health issues. Moreover, because the vast majority of these studies have employed quantitative methodology, they have had the unfortunate effect of dehumanizing and devaluing the Roma people through scientific reductionism.

The purpose of this study was to gain …

The Student Achievement Decline At Sixth Grade And The Practices Impacting Achievement, Mary Cooksley

This mixed method study focused on the practices impacting student performance between the fifth grade and the sixth grade. Research related to the decline of sixth grade student achievement reveals the possible factors resulting in lower achievement: Grade span configuration, the transition between fifth and sixth grade, adolescent development and middle level …

The Effect Of Race On Eyewitness Identification Lineup Processing Strategies: An Analysis Of Eye Movements, Ryan Betts

Dissertations and Theses @ UNI

Race plays an extremely important role in people's ability to recognize or identify an individual in an eyewitness identification situation. In particular, other-race faces are more poorly recognized than same-race faces. This phenomenon, known as the cross-race effect, compounded by problematic lineup administration, contribute to the hundreds of falsely convicted people who continue to be exonerated through DNA evidence to this day. The current study focused on the role that race plays in an eyewitness's decision making strategy when viewing simultaneous police lineups. Eye tracking methodology was used to analyze eye movements and fixations while viewing lineups that were of …

Keeping It Green: Using A Compost To Improve Student Learning, Spencer Mesick, Kayla Hendrix

Iowa Science Teachers Journal

This article discusses ways in which composting might be used to mentally engage students with science content. Incorporating a compost pile in the classroom provides ample connections to future science content (e.g., conditions necessary for the life of organisms in a well running aerobic compost, what decomposition means in a biological sense, aerobic vs. anaerobic decomposition, food webs, respiration, recycling of nutrients, landfill issues, etc.). Also, reflecting the complexities of effective science teaching, the article makes clear the crucial role of the teacher during the activity. The science content and activity addressed in this article are appropriate for 9th - …

When Dissatisfaction Is A Good Thing, Michael P. Clough, Jerrid Kruse

Iowa Science Teachers Journal

Our previous editorial (Clough and Kruse, 2010) in the Iowa Science Teacher Journal used conceptual change theory (Posner, 1982; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006) to highlight the similarities between students learning science content and educators learning to teach well. An important part of conceptual change is first acknowledging and then confronting current ways of thinking. That is, before learners (whether children or adults) will consider altering their thinking, they must first develop some sense of dissatisfaction with their currently held ideas. That can be difficult because the ideas people hold do appear to work — …

Exploring The Depths: Inquiry To Apply And Deepen Students’ Understanding Of Density, James M. Sleep, Lee Johnson

Iowa Science Teachers Journal

This activity is designed to deepen students' understanding of the concept of density through scientific inquiry. Students devise procedures to determine the relative and absolute (qualitative and quantitative) densities of several solutions of salt water, and establish a class consensus on their results. Students then apply their findings to estimate the density of an unknown solution. The targeted grade-level for this activity is 8 grade physical science. However, because we know students at all grade levels struggle to understand density, this activity could also be useful in high school Earth science and chemistry. This activity promotes National Science Education Content …

Temperature Rising: Investigating Rates Of Temperature Change, Jacob Norlin, Daryl Miller

Iowa Science Teachers Journal

This exploratory activity, designed for secondary physical science or earth science students, investigates rates of temperature change over bodies of water and land. Students discuss temperature trends of several cities across the United States, which creates an opportunity to conduct classroom experiments to explain these trends. Students write procedures and generate data of temperature changes between areas of water and land. Students gain a valuable, concrete experience of temperature changes which in turn enables them to better understand and explain why similar cities experience vastly different temperature patterns. This activity can then serve as a basis to address the abstract …

Confronting Doubts About The Intelligibility, Plausibility, And Fruitfulness Of Inquiry-Based Instruction, Jerrid Kruse, Michael P. Clough

Iowa Science Teachers Journal

Our two prior ISTJ editorials in the Iowa Science Teacher Journal (Clough & Kruse, 2010a & 2010b) have applied a conceptual change framework (Posner, Strike, Hewson & Gertzog, 1983; Pintrich et al., 1993; Abd-El-Khalick & Akerson, 2004; Clough, 2006a) to understand the difficulties students have in abandoning their intuitive ideas about the natural world and, for the same reasons, the difficulties teachers have in jettisoning their intuitive and learning. Our last editorial noted that in both cases, dissatisfaction with prior ways of thinking must be achieved before alternative ways of thinking will be seriously sought and considered. To initiate a …

Thinking On Paper: Using Science Notebooks To Increase Active Engagement In The Elementary Science Classroom, Kimberly R. Gasaway

Iowa Science Teachers Journal

The need for scientific literacy is becoming a new standard to which school districts are being held accountable. Student inquiry and the ability to “think like a scientist” will increase the depth at which students understand the natural world and make connections that are critical in strengthening students' scientific literacy. In addition, research has shown that when students were actively engaged in the learning process, they participated more enthusiastically and retained the concepts being taught. Science notebooks help students learn to record and make sense of data and observations about the natural world and come to deeper understanding of scientific …

Creating Family Through Foster-Adoption: Media Portrayal Of The Foster Care System In The U.S., Kimberly A. Powell

Iowa Journal of Communication

As adoption has gained attention in the media, the focus tends to have been on international and private adoptions, and less on adoption from foster care. When the focus is on foster care, the coverage is most often negative, which is perhaps why there are less adoptions from foster care than there are private and international adoptions. This study of mainstream newspaper coverage of United States foster care adoption from 1992-2005 explores how themes in the media have resulted in a narrow view of foster care and adoption.

New Media Globalization In Asia: The Online Game Industries Of South Korea, Singapore, And China, Peichi Chung

Iowa Journal of Communication

This paper examines the emerging media flow in the new media economy of Asia by focusing on the networking of media exchange among three growing production centers. It argues that the nation-state has come to play an increasingly important role in the development of a pan-Asian cultural economy in the online gaming industries of Asia. New cultural production centers have created a rising regional growth corridor between South Korea, Singapore and China. This paper concludes that this emerging growth corridor in Asia redefines the power relationship between core and periphery in the global media industry in ways that affect the …

The Game Of Being Social: Web 2.0, Social Media, And Online Games, Larissa Hjorth

Iowa Journal of Communication

As the Internet confluences into the creative social networking potentialities of Web 2.0 localities, the techno-social fabric of online gaming dramatically shifts. Once the preoccupation of 'hardcore' gamers, MMOGs (massively multi-player online games) have now become casualized (Juul 2009) and part of the daily diet of many millions of social networking sites (SNS) users. This is particularly apparent in the Asia-Pacific region in locations such as China and Singapore. In this paper I will explore the rise of 'Web 2.0' and its types of social labour (i.e., playbour and produsers), epitomized by SNS, that have led to the growth of …

Meaningful Distributed Instruction— Conceptual Previews For Symbolic Procedures, Edward C. Rathmell

Faculty Work

Understanding a symbolic procedure means far more than “getting the right answer.” A mathematical symbolic procedure or written skill involves step-bystep thinking that leads from a computational problem to a solution. Memorizing this step-by-step procedure may enable a student to answer the problem, even answer it correctly. Yes, that is important, but understanding means much more.
