The Effect of an Overall Rating Item on Halo Error in Performance Evaluations

Hogue, S. Elizabeth 01 May 2010 (has links)
This study focuses on how the presence or absence of an overall rating item on a performance evaluation form affects levels of halo error and satisfaction with the form. Participants included undergraduate college students who were randomly assigned to groups receiving a form with or without an overall rating item at the beginning of the form. A satisfaction item was included on both forms. The analyses included a z-test for correlations from independent samples to determine the difference between the two evaluation forms and a t-test to determine the difference between the satisfaction scores of the two forms. The analyses indicated that the differences between the groups were not significant for levels of halo error or satisfaction.

Examining the Relationship between Criticism and Muscle Dysmorphia Symptomotology in Collegiate Men

Menees, Lauren M. 01 July 2010 (has links)
The goal of the current study was to examine the relationship between critical comments that men can recall others making about their bodies and their current level of Muscle Dysmorphia (MD) symptomotology. Participants (N = 118) were recruited via study board from a mid-Western university with a population of 20,674 students. The hypothesis of the current study was that men who can recall critical comments about their bodies will report more MD symptomotology than those who remembered no such comments. In addition, it was expected that out of those who recall critical comments, the more severe or threatening they remember the comment being, the more MD symptomotology they will report. In this study it was also expected that men who associate more negative emotions with the comment will have higher levels of reported MD symptomotology. To evaluate the first hypothesis, an independent samples (-test was used. Results did not support this hypothesis, and no significant differences were found on MD symptoms between participants who recalled comments about their bodies and those who did not recall such comments. These results are not consistent with previous research that was conducted on women with eating disorders which found that female athletes with disordered eating habits were more likely to recall critical comments made about their bodies than women without disordered eating habits. Results supported the second and third hypotheses. Correlational analyses were conducted to determine if there was a relationship between how threatened a participant reported being from the critical comment made about his body and his current level of MD symptomotology. A significant correlation was found. A correlational analysis revealed that there was a significant relationship between associating negative emotions with the critical comment and having higher levels of MD symptomotology. The participants in the study were asked to name who made the comment about their bodies. The most commonly named person was a friend, followed by a coach, and then a girlfriend. Additional tests showed that there was no significant correlation between how long ago the comment occurred and participants' levels of MD symptoms. However, there was a significant relationship between how well a person remembered the comment and his current level of MD symptomotology. Results from this study extend on what is known about MD and the effects of criticism. Although there was no significant relationship between one's ability to recall critical comments made about his body and his current level of MD symptomotology, there was a significant relationship between finding the comment threatening and associating negative emotions with the comment, if one was reported, and one's current level of MD symptomotology. One limitation of the study is that all of the data was gathered via self-report measures. Data may have been affected by poor recall by the participants as well as denial of symptoms. Also, all of the participants attended Western Kentucky University. There was little diversity in regards to age and race.

An Examination of Body Dissatisfaction and Media Exposure

Kirchmeyer, Richard H 01 December 2009 (has links)
The goal of the current study was to examine the relationship between muscle magazine consumption and body dissatisfaction. The study also examined the relationship between muscle magazine consumption and the amount of disparity between ideal and real body shape. Participants (N = 108) were recruited via study board, and also on a volunteer basis, from a mid-Western university with a population of 20,674 students. The first hypothesis stated that men with greater exposure to muscle magazines would indicate that their actual body shape falls further away from their ideal body shape, in terms of both muscularity and fat level, than men who read fewer magazines that focus on muscle building. The second hypothesis stated that men with greater exposure to muscle magazines would indicate higher levels of body dissatisfaction than men who read fewer magazines focused on muscle building. To evaluate the first hypothesis, a linear regression analysis was conducted to determine whether magazine consumption would predict the distance between real and ideal body shape, in terms of both fat and muscle content. Results did not support the first hypothesis and are not consistent with prior research that showed higher levels of muscle and fitness magazine consumption correlating positively with a greater drive for thinness and a greater drive for muscularity. Results did not support the second hypothesis: greater exposure to muscle magazines did not lead to greater levels of body dissatisfaction. Regression analysis found that there was no predictive relationship between muscle magazine consumption and body dissatisfaction or muscle magazine consumption and greater distance between ideal and real body shapes. Additional t-test analysis found that men who read muscle magazines actually indicated significantly lower levels of dissatisfaction with their bodies than men who did not read muscle magazines; however, that result is restricted to collegiate athletes only. Results from this study are important in that they indicate, in men, there are other factors involved in determining how individuals end up with increased levels of body dissatisfaction. Prior findings also concluded that men’s concerns with body shape thrive as a combination of multiple constructs involving social, personal, and mass media factors. Although magazine literature has some bearing on body image concern, particularly with women, it is unclear as to whether magazine consumption contributes to its effect on men. One limitation of this study is that participants reported on the degree to which they were dissatisfied with their bodies. Some individuals may not have acknowledged their level of dissatisfaction with their own bodies. Information based upon self-reporting measures may have been inaccurate due to under or over reporting in surveys. Another limitation of this study, particularly when using the results as a comparison tool toward previous studies, is that the measures used to determine levels of body dissatisfaction differ. Researchers abroad have used different measures to arrive at what would be considered similar conclusions regarding body dissatisfaction. There are multiple measures that can be used to determine a person’s level of satisfaction and drive for muscularity. Some measures are better than others at capturing variable characteristics. Another important limitation is that muscle magazines only represent one form of media consumption. A study that incorporated other forms of media may be more fruitful in its findings. Therefore, results should be interpreted with caution. However, with everexpanding information technology capabilities, society is increasingly bombarded with information more so than ever before. This study provides additional insight into the question of whether or not more is better. It also identifies a gender difference in the predicting power of magazine consumption and body dissatisfaction.

The Effects of Picture Presentation on Male Body Shame and Muscle Dysmorphia

Wilson, Samantha A. 01 May 2010 (has links)
The purpose of this study was to investigate whether picture presentation influenced men’s experienced body shame or Muscle Dysmorphia symptomatology, and whether there was a relationship between body shame and Muscle Dysmorphia. Participants were 112 men attending Western Kentucky University. Participants completed the Body Shame Questionnaire and Muscle Dysmorphia Inventory. Participants were randomly assigned to either view eight photographs of average men or eight photographs of muscular men. After viewing the photographs, the participants completed the Objectified Body Consciousness Scale and the Muscle Appearance Satisfaction Scale. Although there was a trend, results indicate that men who view photographs of muscular men do not experience more body shame than those who view photographs of average men. In the sample, 63.5% reported that they were dissatisfied with their bodies, 69% with their chest size, 69% with their own body build, 65% with their arms, and 63% were dissatisfied with their own abdomen. Results indicate that viewing photographs of muscular men does not increase one’s symptomatology of MD. However, there was a positive correlation between body shame and muscle dysmorphia symptoms for both men who viewed photographs of muscular men and those who viewed photographs of average men.

Knowledge of Nonsuicidal Self-Injury in Populations That Self-Injure

Cates, Darcy Leanne 01 August 2010 (has links)
Archived data was utilized for the present study which examined knowledge about non-suicidal self-injury, or NSSI, in individuals who engage in various degrees of the behavior and those who do not self-injure. Knowledge about NSSI was measured in three groups of respondents: those with no history of self-injurious behavior (no NSSI group), those with more limited experience with NSSI who reported 1-30 incidences of NSSI (limited NSSI group), and those with an extensive history (extensive NSSI group) who reported over 30 incidences of NSSI. To measure knowledge, participants were asked level of agreement with myths and facts about NSSI using Jeffery and Warm’s (2002) knowledge measure. It was hypothesized that the knowledge base would be higher in individuals with more extensive histories of NSSI. Further, individuals with limited histories of NSSI were predicted to have more knowledge than those who have never self-injured. Additionally, this study also hypothesized that the individual item response will vary; depending on extent of NSSI behavior. Group mean scores on the measure were analyzed for differences using a one-way analysis of covariance (ANCOVA) while controlling for the differing group demographic variables of age, sexual orientation, and education level. Results indicated that individuals who have more extensive histories of NSSI evidenced higher mean scores on the measure when controlling for age, sexual orientation and educational level. Individuals with limited histories of NSSI evidenced lower mean scores, and those with no history of NSSI evidenced the lowest scores. In regard to individual item response, items were correlated with seven levels of NSSI (no NSSI, one incident of NSSI, 2-4 incidences, 5-10 incidences, 11-20 incidences, 21-30 incidences and more than 30 incidences). It was found that accuracy was significantly correlated with degree of self-injurious behaviors, with the exception of one item. This item and three additional items also produced weak correlations with other items on the measure. Each item is discussed with regard to group item performance and possible deletions in order to strengthen the measure. Overall, the results of this investigation supported the reliability and validity of the Jeffery and Warm (2002) knowledge measure for use with individuals who self-injure. Results are discussed in relation to the need for accurate knowledge about NSSI, the importance of refining and strengthen the measure for this use, and additional research directions.

Exploration of the Relationship between Moral Judgment Development and Attention

Clark, Lauren I. 01 August 2010 (has links)
Research in moral psychology has focused on understanding what factors assist in the development of moral action and decision making. The purpose of this study was to address whether variability in attention relates to moral judgment development. The reason for exploring moral judgment development was to further explore the research of Thoma and Bebeau (2008) who documented that the moral development scores of college and graduate students has been declining over time, with more college-aged students scoring in the lower levels of moral reasoning. Attention was chosen as a viable topic of research, based on the writings of Carr (2008a) who suggests that technology has had an impact on the way that individuals read and process information. College students from Western Kentucky University were recruited via the Psychology Department Study Board. Participants first took the Defining Issues Test-2 (DIT2) online and then scheduled a subsequent session in the laboratory to take the Test of Everyday Attention (TEA). The DIT2 assesses three levels of moral reasoning advancing by level: Personal Interests, Maintaining Norms, and Postconventional schemas. The TEA assesses four different types of attention: divided attention, attentional switching, selective attention, and sustained attention. In a sample of 79 college students, results revealed that stronger attention abilities were related to higher postconventional reasoning. However, decreases in attention were not related to lower personal interests reasoning. Attentional switching, selective attention, and sustained attention were particularly influential where postconventional reasoning was concerned. The trends observed in this study were somewhat expected as moral judgment development is regarded and verified as a cognitive intellectual process. In light of the information provided by the results of this study, future studies are recommended to determine how efforts to facilitate improved attention might ultimately translate to improved moral judgment development. Research has shown that interventions aimed at improving attention are successful (Kerns, Eso, & Thomson, 1999). In conclusion, this study supports the notion that attention does pertain to moral judgment scores as inferred by the DIT2. The effect of the TEA scores on the DIT2 postconventional scores was strong (R2 = .237).

A latent-segmentation based approach to investigating the spatial transferability of activity-travel models

Wafa, Zeina 20 January 2015 (has links)
Spatial transferability of travel demand models has been an issue of considerable interest, particularly for small and medium sized planning areas that often do not have the resources and staff time to collect large scale travel survey data and estimate model components native to the region. With the advent of more sophisticated microsimulation-based activity-travel demand models, the interest in spatial transferability has surged in the recent past as smaller metropolitan planning organizations seek to take advantage of emerging modeling methods within the limited resources they can marshal. Traditional approaches to identifying geographical contexts that may borrow and transfer models between one another involve the exogenous a priori identification of a set of variables that are used to characterize the similarity between geographic regions. However, this ad hoc procedure presents considerable challenges as it is difficult to identify the most appropriate criteria a priori. To address this issue, this thesis proposes a latent segmentation approach whereby the most appropriate criteria for identifying areas with similar profiles are determined endogenously within the model estimation phase, customized for every model type. The end products are a set of optimal similarity measures that link regions to one another as well as a fully transferred model, segmented to account for heterogeneity in the population. The methodology is demonstrated and its efficacy established through a case study that utilizes the National Household Travel Survey (NHTS) dataset for information on weekday activities unemployed individuals within 9 regions in the states of California and Florida engage in. A multiple discrete continuous extreme value (MDCEV) model is developed that simulates the discrete nature of activity selection as well as the continuous nature of activity participation. The estimated model is then applied onto the Austin–San Marcos MSA, a context withheld from the original estimation in order to assess its performance. The performance of the segmented model was then examined vis-à-vis that of other models that are similar to the local region in only one dimension. It is found that the methodology offers a robust mechanism for identifying latent segments and establishing criteria for transferring models between areas. / text

Learning to Use Student Ideas in Elementary Science Teaching: The Influence of Mentor Teachers in Preservice Teachers' Developing Meanings

Schaub, Elsa Nunes January 2014 (has links)
This study explores the influence of mentor teachers in the meanings and practices that two elementary preservice teachers adopted about eliciting and using student ideas, while learning to teach science in the university science methods course and in the field placement classroom. Prior research on teacher development has shown that the high-leverage practice of eliciting and using student ideas can support preservice teachers in thinking about common problems of practice. I used four core problems of practice to examine the meanings and practices that preservice teachers adopted in eliciting and using student ideas as they planned, enacted and reflected on methods course assignments in the field placement classroom. Using sociocultural and situative perspectives on learning, I identified two factors that influenced the sense that preservice teachers constructed and the practices that they adopted about eliciting and using student ideas. These factors were mentor teacher's perspectives on learning and goals for student learning. I also examined three mechanisms by which mentor teacher's perspectives and goals influenced preservice teacher meanings and practices about eliciting and using student ideas in instruction, including mentor teacher's classroom practice, the nature and foci of mentor teacher and preservice teacher conversations and mentor teacher's use of preservice teachers' ideas in their conversations about instruction. The results suggest that preservice teachers come to make sense of and use student ideas in their instruction in ways that closely align with those of their mentors. They also indicate that preservice teachers' integration of experiences from different learning-to-teach contexts in making sense of student ideas may be related to the degree of alignment between mentor teachers' perspectives and goals and the perspectives and goals of the science methods course.

Arbetsplatsens lärmiljöer : En organisationspedagogisk studie av konstruerande av lärmiljö i vuxenutbildningsverksamhet / Learning Environments in the Workplace : The Construction of Learning Environments in a VET-program from an Organizational Pedagogical Point of Departure

Johansson, Peter January 2011 (has links)
Today’s research on workplace learning stresses the importance of the environment in which learning takes place. On the basis of an empirical study of a Vocational Education and Training (VET) program this thesis aims to create knowledge about how a learning environment is constructed. Theoretically, the study is based within action theory and takes an organizational pedagogical point of departure. It is rooted both in constructivist theory, as well as draws on the theory of learning as culturally and socially situated. The study is designed as a single case study. Data was primarily collected during periods of field studies through the observation of teachers’ work inside and outside classroom settings; recurring in-depth interviews with six teachers and eight participants, and reflection group interviews with the teachers. The study reveals a difference between participants’ and teachers’ educational goals and ambitions. This is important to acknowledge due to the necessity for the teachers to handle the difference. It gives information on daily work in the VET-program and the important work tasks that emerge. The program is influenced by the ideological foundations developed by its principal organizer, which comes to play as a special way of reasoning, the Yes-thought. Much of the daily work consists of an adjustable way of working and an approach that supports it. However, two tension fields can be identified in which discretion in work tasks is created. The first concerns the approach to work tasks, and is a tension between dynamic and instrumental approaches. The second concerns the organizing of work tasks and is a tension between adjustable and regulating ways of working. Micro context is introduced as a concept, referring to the context of meaning which is created around work tasks. Depending on the micro context’s position in the two tension fields, different conditions of learning can be identified. The micro contexts can then be understood as the learning environments in the work place.

Islamic Activism in Azerbaijan : Repression and Mobilization in a Post-Soviet Context

Bedford, Sofie January 2009 (has links)
Post-Soviet Azerbaijan is often portrayed as a very secular country. Thus the mobilization of mosque communities in the late 1990s and their conflictual relationship with the authorities came as a surprise. The main aim of the dissertation is to shed light on this mobilization, focusing on the Sunni Abu Bakr and the Shi’ite Juma mosque communities in Baku. On the premise that Islamic mobilization may be interpreted as a “social movement”, internal, contextual and interactional aspects of mobilization have been studied. The analysis is chiefly based on interviews conducted in Baku in 2004/2005 with Imams, worshippers, religious and secular authorities. The study finds that young people looking for new approaches to religion have been drawn to these communities, where they encounter an independent, educated, conscientious clergy and, indeed, a “new” religion. This “sovereign” Islam does not go down well with authorities who fear politicization of religion. The Soviet heritage has provided them with a view of religion as something that should not be publicly displayed and with the institutions to control religion. Another key feature whose impact on state policy towards religious organizations cannot be underestimated is the fear of imported radicalism. A look at Islamic mobilization in North Caucasus, Tajikistan and Uzbekistan reveals many similarities, yet one momentous difference is the harsher repression in these contexts, which decreases the chances of a non-radical mobilization. The thesis concludes that the role of the state in mobilization processes in non-democratic contexts is crucial but counterintuitive, as the regimes’ efforts to stop the mobilization of movements actually leads to its intensification. In Azerbaijan, official pressure brings community members closer together and strengthens their resolve, rather than putting an end to mobilization. It also puts a spotlight on these communities which lights up the way for others in search of something new.
