Anger-Expression Avoidance In Organizations In China : The Role Of Social Face, Xu Han

Lingnan Theses

Chinese people have been theorized to be particularly sensitive to social face and avoid direct discussion in conflict to promote interpersonal harmony. This study uses the theory of social face to predict Chinese employees’ strategies to avoid expressing anger with their supervisors in the organizations. Inspired by previous research, this study proposes that anger-expression avoidance is a complex behavior with different motivations and actions, leading to diverse outcomes. It identifies four strategies for the employees to avoid expressing anger with their boss; they are named outflanking (turn to the third party to resolve the anger), withdrawal (staying cool, ignoring, giving …

Perinatal Risk Factors For Developmental Coordination Disorder, Beth P. Hands, Garth Kendall, Dawne Larkin, Elizabeth Rose, Helen Parker

Health Sciences Papers and Journal Articles

The aetiology of mild motor disability (MMD) is a complex issue and as yet is poorly understood. The aim of this study was to identify the prevalence of perinatal risk factors in a cohort of 10-year-old boys and girls with (n = 362) and without (n = 1193) MMD. Among the males with MMD there was a higher prevalence of postpartum haemorrhage, caesarean section, low birth weight and stressful first year of life. Among the females with MMD, there was a higher prevalence of essential hypertension, anaemia, and threatened pre-term. Multivariable logistic regression revealed gender (male), anaemia, threatened pre-term birth …

Self-Renewal Of The Long-Term Reconstituting Subset Of Hematopoietic Stem Cells Is Regulated By Ikaros, Peter Papathanasiou, Joanne L. Attema, Holger Karsunky, Naoki Hosen, Yovina Sontani, Gerard F. Hoyne, Robert Tunningly, Stephen T. Smale, Irving L. Weissman

Health Sciences Papers and Journal Articles

Hematopoietic stem cells (HSCs) are rare, ancestral cells that underlie the development, homeostasis, aging, and regeneration of the blood. Here we show that the chromatin-associated protein Ikaros is a crucial self-renewal regulator of the long-term (LT) reconstituting subset of HSCs. Ikaros, and associated family member proteins, are highly expressed in self-renewing populations of stem cells. Ikaros point mutant mice initially develop LT-HSCs with the surface phenotype cKit+Thy1.1(lo)Lin(-/lo)Sca1+Flk2-CD150+ during fetal ontogeny but are unable to maintain this pool, rapidly losing it within two days of embryonic development. A synchronous loss of megakaryocyte/erythrocyte progenitors results, along with a fatal, fetal anemia. At …

Zinc-Finger Protein Mcpip In Cell Death And Differentiation, Craig Younce

Electronic Theses and Dissertations

Monocyte chemotactic protein-1 (MCP-1) plays a critical role in the development of cardiovascular diseases. How MCP-1 contributes to the development of heart disease is not understood. We present evidence that MCP-1 causes death in cardiac myoblasts, H9c2 by inducing oxidative stress, ER stress and autophagy via a novel Znfinger protein, MCP-1 induced protein (MCPIP). MCPIP expression caused cell death and knockdown of MCPIP, attenuated MCP-1 induced cell death. Expression of MCPIP resulted in induction of iNOS and production of reactive oxygen (ROS). It caused induction of NADPH oxidase subunit phox47 and its translocation to the cytoplasmic membrane. Oxidative stress led …

Videotaped Oral Reading Fluency Lab: An Alternative Approach To One-On-One Interventions For Intermediate Elementary Students With Learning Disabilities, Beth Christner

Electronic Theses and Dissertations

The ability to read aloud fluently is a reflection of one's ability to automatically decode words and comprehend text at the same time (Samuels, 2006), a task which may be difficult for many intermediate elementary students with learning disabilities (LD) (Ferrara, 2005). Previous research shows that audio-assisted repeated readings and goal-setting with feedback are effective methods of improving oral reading fluency (ORF) (Chard, Vaughn, & Tyler, 2002; Morgan & Sideridis, 2006; Therrien, 2004) but implementing these interventions may be time-consuming for teachers and tedious for students. The purpose of this research was to determine the impact of including repeated reading …

Exploring The Relationship Between Marital Expectations And Marital Satisfaction Between Married African Immigrant Couples And U, Evadne Ngazimbi

Electronic Theses and Dissertations

Marriage is still considered a universal institution in many countries worldwide. Marriage provides benefits for wives, husbands, children, families, and communities. Why Marriage Matters (Wilcox et al., 2005), outlined the benefits of marriage, including improved physical and mental health, biological and social benefits for husbands, wives, children and families in America. In sub-Saharan Africa benefits emanating from marriage included increased survival rates for young children (Omariba & Boyle, 2007); reduced maternal morbidity and mortality rates for women due to reduced risks from self-inflicted abortions (Garenne, Tollman, Kahn, Collins, & Ngwenya, 2001); and improved economic management in homes due to exchanging …

Ucanfnsh: A Virtual Learning Environment Created To Engage And Inspire Self-Determination In Middle School Students With Learnin, Kara Rosenblatt

The primary purposes of this study were (a) to investigate the relationship between counseling interns' site supervisors' experience and training in supervision and their own levels of ego development and (b) to investigate the relationship between supervisors' levels of ego development and the ego functioning and occupational stress of their intern-supervisees. The theoretical framework for this investigation included cognitive developmental models of supervision (e.g., Blocher, 1983; Stoltenberg, 1981), ego development (Loevinger, 1976, 1997) and the Person-Environment Fit theory of occupational stress (French, Rogers, & Cobb, 1974). The findings of this study contribute to an understanding of (a) the levels of …

Mystery Shopper Motivations And The Presence Of Motivation Crowding, Pamela Allison

Electronic Theses and Dissertations

Mystery shopping is used in a variety of service industries to measure service performance, as a training tool for employees, and to ensure the safety and security of the product offered. The persons performing this activity, mystery shoppers, experience various motivations, some of which are similar to employees and/or volunteers. These motivations can be intrinsic, where the performance of the activity is a reward itself, or extrinsic, meaning performance of the activity is a method for attaining a reward. The dominance of intrinsic or extrinsic motivation can shift within the individual, which is termed motivation crowding. Individuals can crowd in …

Participants in this study were 148 undergraduate students from …

Tourists' Attitudes Toward The Use Of Animals In Tourist Attractions: An Empirical Investigation, Amir Shani

Electronic Theses and Dissertations

From time immemorial human beings have utilized animals for various needs and purposes, which led societies to debate the justification for using animals and to reflect on the way in which animals are treated. These concerns have also resulted in various contemporary studies aimed to reveal interest groups'--as well as the general publics'--views and opinions on the issues under dispute. Nevertheless, despite the considerable incorporation of animals in entertainment and leisure venues, only limited efforts have been geared towards exploring the ethical aspects of using animals in these initiatives. This lack of attention is especially evident in the tourism literature, …

Evaluation Of Juvenile Justice Education Programs: What The Numbers Say About Juvenile Recidivism, Kevin Egan

Electronic Theses and Dissertations

Each year more than 100,000 juveniles are incarcerated in residential rehabilitative facilities. As part of their course of treatment, educational services are mandated for these incarcerated youth. Programs serving these individuals must provide adequate and appropriate educational programs for these juveniles. With a growing public concern over juvenile delinquency and recidivism, programs are being held accountable for the effectiveness and quality of the programming they offer. In Florida, juvenile justice programs offering educational services are monitored annually by the Juvenile Justice Education Enhancement Program. These programs receive a Quality Assurance (QA) rating as determined by a review team that spends …

Interrater Reliability Of Psychomotor Skill Assessment In Athletic Training, Jason Craddock

Electronic Theses and Dissertations

Assessment in athletic training education is an evolutionary process that is determined by each individual Athletic Training Education Program. The autonomy authorized by national accreditation standards allows academic programs to determine the appropriate assessment practices that facilitate the meeting of student learning outcomes. Even with autonomy, formative and summative techniques are to be employed in both the didactic and clinical arenas of athletic training education programs. The major objective of athletic training education is to prepare students for entry-level practice in athletic training. The purpose of this study was to assess interrater reliability of athletic training faculty and approved clinical …

Measurements were based on Richard Clarke's Commitmemt and Necessary Effort (CANE) theory, severity of disability, and demographic factors including teaching assignment, number of students in class, number of years teaching and number of years working in an inclusive setting. A four-point Likert-type survey(Appendix A) adapted from a combination of Spencer Salend's (2008) "Teacher's Inclusion Survey and Interview Question to examine the Experience of …

An Examination Of An Antecedent And Consequences Of Supervisor Morally Questionable Expediency, Rebecca Greenbaum

Electronic Theses and Dissertations

Supervisor morally questionable expediency occurs when subordinates perceive that their supervisors engage in morally questionable behavior to expedite their work for self-serving purposes (Greenbaum & Folger, 2008). A supervisor's preoccupation with the bottom-line (Greenbaum, 2007; Greenbaum & Folger, 2008; Wolfe, 1988) is examined as an antecedent of morally questionable expediency. It was hypothesized that subordinates experience deontic reactions (Folger, 2001) in the form of a moral psychological contract violation. Consequently, subordinates were hypothesized to reduce performance, engage in antisocial behavior and supervisor-directed deviance. Survey data from 259 subordinate-supervisor dyads provided general support for this hypothesized model. However, post hoc analyses …

Neurocognitive Correlates Of Body Image Disturbance, Elizabeth Frei

Electronic Theses and Dissertations

Body image, broadly defined as an individual's general experience of his or her physical appearance, is a multidimensional phenomenon that has been found to affect functioning throughout the lifetime. Although some degree of dissatisfaction has been found to be a common aspect of the female experience, research suggests that a disturbance in body image can result in a number of clinical complications, particularly the development of an eating disorder (ED). Despite the relationship between body image and EDs, examinations of the cognitive underpinnings of the relationship between body image disturbance and EDs are relatively few and inconclusive. Research indicates that …

Association Between Unirhinal Olfactory Processing And Self-Reported Empathy In Schizophrenia, Vidyulata Kamath

Electronic Theses and Dissertations

Empathy represents one multifaceted component of social cognition that is thought to be significantly impaired in individuals with schizophrenia. Psychophysical tasks of smell identification and hedonic processing of pleasant, neutral, and unpleasant odors share common neural networks involved in empathy. Therefore, we investigated the relationship between odor identification, odor ratings, and self-reported empathy in 25 outpatients with schizophrenia and 25 nonpsychiatric individuals. Group differences on empathy scores and unirhinal smell identification performance (with hedonic and intensity ratings) were examined, along with the relationships between smell identification scores, self-reported empathy, and schizophrenia symptomatology. The preliminary findings suggest that individuals with schizophrenia …

Different Time, Same Place, Same Story? A Social Disorganization Perspective To Examining Juvenile Homicides, Minna Laurikkala

Electronic Theses and Dissertations

In 2007, juveniles were involved in a minimum of 1,063 murders in the United States (Federal Bureau of Investigation, 2008), and a concern over juvenile homicide offenders remains. While increasingly more macrolevel research on juvenile homicide offending has been accumulated, particularly since the 1980s, research focusing on macrolevel correlates of juvenile homicides is still relatively scarce (MacDonald & Gover, 2005; Ousey & Campbell Augustine, 2001). In the first part of this study, several variables relating to the offender, victim, setting, and precursors to the homicide by race and gender were examined in order to provide details on the context of …

Man Up Or Punk Out: The Role Of Masculinity In Prison Rape, Melanie Carlson

Electronic Theses and Dissertations

Using the dataset, "Ethno-Methodological Study of the Subculture of Prison Inmate Sexuality in the United States, 2004-2005," this study investigated the relationship between masculinities and prison rape. These data was collected in 23 men's correctional institutions in 10 states. Between April 2004 and September 2005, 409 males were interviewed (Fleisher & Krienert, 2006). Findings showed that masculinity plays a complex and crucial role in the phenomenon of prison rape. Recommendations were made for inmate-oriented education and training which should include a discussion of masculinity as a possible preventative measure.

Gabor Domain Optical Coherence Microscopy, Supraja Murali

Electronic Theses and Dissertations

Time domain Optical Coherence Tomography (TD-OCT), first reported in 1991, makes use of the low temporal coherence properties of a NIR broadband laser to create depth sectioning of up to 2mm under the surface using optical interferometry and point to point scanning. Prior and ongoing work in OCT in the research community has concentrated on improving axial resolution through the development of broadband sources and speed of image acquisition through new techniques such as Spectral domain OCT (SD-OCT). In SD-OCT, an entire depth scan is acquired at once with a low numerical aperture (NA) objective lens focused at a fixed …

Epigenetic Control Mechanisms In Somatic Cells Mediated By Dna Methyltransferase 1, Bongyong Lee

Electronic Theses and Dissertations

DNA methylation regulates gene expression through a complex network of protein/protein and protein/DNA interactions in chromatin. The maintenance methylase, DNA methyltransferase 1 (DNMT1), is a prominent enzyme in the process that is linked to DNA replication and drives the heritable nature of epigenetic modifications in somatic cells. The mechanistic details that explain how DNMT1 catalytic action is directed in a chromatin setting are not well understood. We hypothesize that post translational modifications and a variety of protein-protein interactions processes are key regulatory elements that set the methylation of CpG elements essential for normal growth behavior in somatic cells. These fundamental …

Boreal Forest Fire Impacts On Lower Troposphere Carbon Monoxide And Ozone Levels At The Regional To Hemispheric Scales, Kateryna Lapina

Dissertations, Master's Theses and Master's Reports - Open

Tropospheric ozone (O3) and carbon monoxide (CO) pollution in the Northern Hemisphere is commonly thought to be of anthropogenic origin. While this is true in most cases, copious quantities of pollutants are emitted by fires in boreal regions, and the impact of these fires on CO has been shown to significantly exceed the impact of urban and industrial sources during large fire years. The impact of boreal fires on ozone is still poorly quantified, and large uncertainties exist in the estimates of the fire-released nitrogen oxides (NO _x ), a critical factor in ozone production. As boreal fire activity is …

Development Of Measurement And Modeling Techniques To Quantify Atmospheric Deposition Of Persistent, Bioaccumulative And Toxic Chemicals In The Great Lakes, Mark D. Rowe

Dissertations, Master's Theses and Master's Reports - Open

Measurement and modeling techniques were developed to improve over-water gaseous air-water exchange measurements for persistent bioaccumulative and toxic chemicals (PBTs). Analytical methods were applied to atmospheric measurements of hexachlorobenzene (HCB), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Additionally, the sampling and analytical methods are well suited to study semivolatile organic compounds (SOCs) in air with applications related to secondary organic aerosol formation, urban, and indoor air quality.

A novel gas-phase cleanup method is described for use with thermal desorption methods for analysis of atmospheric SOCs using multicapillary denuders. The cleanup selectively removed hydrogen-bonding chemicals from samples, including much of …

Long-Range Pollution Transport: Trans-Atlantic Mechanisms And Lagrangian Modeling Methods, Robert Christopher Owen

Dissertations, Master's Theses and Master's Reports - Open

Over the past several decades, it has become apparent that anthropogenic activities have resulted in the large-scale enhancement of the levels of many trace gases throughout the troposphere. More recently, attention has been given to the transport pathway taken by these emissions as they are dispersed throughout the atmosphere. The transport pathway determines the physical characteristics of emissions plumes and therefore plays an important role in the chemical transformations that can occur downwind of source regions. For example, the production of ozone (O₃) is strongly dependent upon the transport its precursors undergo. O₃ can initially be formed …

Evidence For Multiple Paternity In Broods Of The Green Lynx Spider Peucetia Viridans (Araneae: Oxyopidae), Martina G. Ramirez

Biology Faculty Works

In the green lynx spider Peucetia viridans (Hentz 1832), the two openings of a mated female’s epigynum are often sealed by copulatory plugs, sometimes with the two-pronged distal portion of the paracybium of a male palpus inserted in each opening and embedded in the plugs. The presence of copulatory plugs and paracymbia may prevent further mating by the female. However, not all mated females exhibit these structures, perhaps allowing some P. viridans females to mate with more than one male, despite the assertion of Whitcomb & Eason (1965) that females only mate once. We investigated this possibility by surveying the …
