Creating a safety culture is the focus in the current healthcare environment. An inhouse, around-the-clock laborist service delivery model has been associated with positive outcomes, but little is known about the laborist structure’s contribution to the labor-anddelivery working environment. The purpose of this descriptive correlational study was to explore the effects of physician service delivery model on safety culture, nurse-physician collaboration, and nurses’ job satisfaction.

Show moreCreating a safety culture is the focus in the current healthcare environment. An inhouse, around-the-clock laborist service delivery model has been associated with positive outcomes, but little is known about the laborist structure’s contribution to the labor-anddelivery working environment. The purpose of this descriptive correlational study was to explore the effects of physician service delivery model on safety culture, nurse-physician collaboration, and nurses’ job satisfaction. An additional purpose was to examine associations between nurses’ perceptions of safety culture, nurse-physician collaboration, and job satisfaction. Ray’s (1981, 1989) Theory of Bureaucratic Caring and Homan’s (1974) Social Exchange Theory guided this study. A survey consisting of demographic questions, the Collaborative Practice Scale (Weiss & Davis, 1985), the Hospital Survey on Patient Safety Culture (Agency for Healthcare Research and Quality, 2015; HSOPSC), and the McCloskey and Mueller Satisfaction Scale (McCloskey & Mueller, 1990) was distributed to registered nurses (RNs) nationwide. The results indicated that nurses in facilities using the around-the-clock model had higher perceptions of nursephysician collaboration, but not of safety culture or job satisfaction in relation to the physician service-delivery model. Significant moderate-to-strong correlations between nurses’ perceptions of patient safety and job satisfaction, and a weak correlation between bedside nurses’ perceptions of nurse-physician collaboration and job satisfaction were demonstrated. Additional significant correlations were found between the instrument subscales. Control/responsibility in the MMSS scale was positively associated with both management support for patient safety, supervisors’ and managers’ expectations and actions promoting patient safety, and overall perceptions of safety in the HSOPSC scale. Praise and recognition in the MMSS scale were positively associated with supervisor/manager expectations and actions promoting patient safety in the HSOPSC scale. Further appraisal is needed to understand the mechanism by which the laborist model affects patient care and work environment. Recommendations for future research include replicating the study with a larger sample sizes in specific groups based on the role and scheduled shift, conducting the study in a single system or location to mitigate the effects of other variables; and exploring physicians’ perspectives on the variables being studied.

Show moreThis study analyzes the reactions of interracial relationships within the South Asian Diaspora via film and literature focused on the United States and England. The films examined are Mississippi Masala (1992) and Bend It Like Beckham (2002), and the literature-utilized focuses on cultural identity, interracial dating, the importance of marriage, the Indian community, and gender roles focused on women within the diaspora. The films used encourage the idea of interracial relationships as acceptable and give South Asian women the confidence to be more independent. The intention of this research is to analyze the importance of cultural blending, independence, heritage, and traditional values. The focus behind this research is to understand the battle of traditional versus modern roles for women in the South Asian diaspora, and how independence can be viewed as a form of dishonoring and humiliating their families when they step outside of the cultural box.

Show moreConsiderable research has been carried out to establish a rodent model for the study of human memory, yet functional similarities between the species remain up for debate. The hippocampus, a region deep within the medial temporal lobe of the mammalian CNS, is critical for long-term episodic memory. Projections from the medial entorhinal cortex convey spatial/contextual information, while projections from the lateral entorhinal cortex convey item/object information to the hippocampus. The functional significance of these parallel projections to the rodent hippocampus has been suggested to support spatial processing, while the same projections to the human hippocampus support spatial and non-spatial memory. Discharging in a location-specific manner, hippocampal place cells contribute to spatial memory; however, evidence for neuronal correlates of non-spatial object memory has not been fully defined. The current experiments were designed to address the following questions, while utilizing electrophysiology, functional inactivation during a novel behavioral task, and immunohistochemistry. Is the memory for objects hippocampal-dependent, solely due to the location of the object, or are objects represented within hippocampal activity independent of location? To tease apart spatial and non-spatial processing by the hippocampus, the spatial aspects of 3D objects were enhanced by utilizing movement. A novel discriminatory avoidance task, Knowing Your Enemy, was adapted from an Enemy Avoidance task to test true object memory in mice. Current findings support the notion that object-associations acquisition depends upon a specific context. Retrieval of such object-associations is not context-dependent, yet remains sensitive to temporary inactivation of the CA1 region of the dorsal hippocampus. The avoidance impairments observed following hippocampal inactivation were shown to not be a result of reduced anxiety. Immunohistochemical marker expression suggests that the CA1 region was highly active during object exposures, yet the hippocampal system responded differentially to moving and to stationary objects. Recordings of CA1 neurons yielded non-bursting object-related activity during object exploration, and place cell activity remained unaffected in the presence of moving objects; supporting independent, yet simultaneous processing of spatial and non-spatial information within the hippocampus. Together, the current findings support the notion that the CA1 region of the rodent hippocampus processes object-related information, independent of spatial information.

Show moreThe present study investigates the affectual interaction of three highly competent therapists using different theoretical approaches with a shared male client and female client in a professionally recorded video series. The interactions of clients and therapists in a total sample of six psychotherapy sessions were coded using the twenty code version of Gottman, Woodin, and Coan’s (1998) Specific Affect Coding System. Coded data were analyzed using Kruskal-Wallis tests which found no significant differences between the mean ranks of therapists’ codes between therapists. Significant effects among some affective behaviors were noted in therapists’ codes when compared by client. Coded data were also used to create mathematical models using ordinary differential equations for each of the six sessions. Kruskal-Wallis tests did not reveal significant effects in the mean ranks of the parameters of the mathematical models, and visual similarities and differences of these models were discussed. Additional analyses were conducted to examine clients’ affective behaviors as well and significant effects were revealed in the Kruskal-Wallis tests amongst many coded behaviors. The results support the presence of common factors and similarities in the therapeutic relationship among different theoretical approaches. The findings also add to the growing body of literature dedicated to the use of observational coding and dynamic nonlinear modeling in psychotherapy research. The implications for psychotherapy practice, education, and research are discussed.

Show moreCurrent literature confirms that self-efficacy, academic self-concept, and participation in undergraduate research influence the academic performance and aspirations of students. However, a gap in the literature remains as research has yet to explore whether students who have participated in research have a higher sense of research self-efficacy and academic self-concept than students who have not participated in these activities. In addition, it is unknown whether undergraduate researchers pursuing STEM degrees differ from students pursuing non-STEM degrees, nor if they vary by gender. The purpose of this study was to investigate the research self-efficacy and academic self-concept of undergraduate researchers, compare these beliefs to nonresearchers, and to examine how these measures differ by gender and field of study (i.e. STEM and non-STEM fields) among undergraduate researchers. Additionally, this research identified various factors that predict research self-efficacy and academic selfconcept. This quantitative study was conducted at a public university located in the Southeast region of the United States. Using survey methods participants’ background information, academic self-concept, and research self-efficacy was collected. Participants were students who had participated in undergraduate research as well as students who had not participated in research activities. Both groups completed the same survey. This study gained insight into the research self-efficacy, academic self-concept, field of study, and gender differences among undergraduate researchers and how they compare to non-researchers. Research findings may assist colleges, universities, and offices that promote undergraduate research in recruiting students to participate in research activities. Findings also contribute to literature supporting undergraduate research as an element that contributes to student success in undergraduate education.

Show moreIn this thesis, I examine the structure of developmental or remedial English education at U. S. two-year community colleges, specifically focusing on the disparities between Florida’s English for Academic Purposes (EAP), an English as a Second Language (ESL) program, and Developmental English (Dev English), a Basic Writing program. Both programs supposedly prepare disadvantaged and/or immigrant students for freshman composition, but they employ very different pedagogies. Drawing on existing research and my own experience as a student and a teacher, I present English as it is employed to assimilate and empower second-language users, investigate the role of Florida’s institution in promoting EAP over Dev English, and discuss issues of identity and the categorization of students. I close by recommending the teaching of English as a Second Language – reading, writing, and basic language skills – to all developmental students, immigrant or native, to equip them for higher learning and a competitive workforce.

Elevated yolk testosterone has facilitated prenatal learning, but its effects on postnatal auditory learning in quail are unknown. Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated. Following hatching, chicks were exposed to a conspecific maternal call (A or B) for 240 min. At 48 hr, chicks were tested for their preference for the familiarized vs. novel call. All groups demonstrated a preference for the familiar call (p < .05), but minimal between group difference were found. Contrary to previous research, elevated yolk testosterone neither facilitated nor impaired postnatal auditory learning in bobwhite quail chicks. Further research will examine underlying mechanisms responsible for differential effects and explore if similar systems are involved in other species-typical processes such as social motivation.

Show moreLolita fashion is a small youth fashion that originated in Japan but is inspired by historical western clothing. The clothing is not sexual in nature. Most studies look at the style in Japan, but the fashion has also found popularity overseas. This paper takes an ethnographic approach to studying the Lolita community in the United States by comparing two regional communities, Houston and South Florida. The research found that the largest difference between the two groups was size and community involvement, with Houston as the larger group and the smaller South Florida group being more concerned with group activity. The study found that compared to the strong subversive element of the wearers in Japan, the United States community at large appears to be motivated by Lolita as a creative outlet. There was no support of the idea that aging played a role in what kind of Lolita fashion was worn.

In this study, unhatched eggs were collected from the Boca Raton, Florida beach and developmental stage at embryonic death determined. Elevated nest temperatures increased embryonic mortality, and the most significant relationship was between mortality and the percent of time embryos were exposed to temperatures above 34°C. Loggerhead turtles exhibited higher rates of mortality compared to green turtles at temperatures above 34°C. Only loggerhead nests were exposed to inundation, but embryonic mortality did not differ from noninundated nests. Beach profiles across the nesting season were also determined. A major storm altered the beach more in areas of coastal development; however, this was impacted by a nourishment project and the presence of a structured inlet. Future management strategies may need to protect sea turtle nests from extended periods at elevated temperatures.

Show moreToni Morrison’s later novels Love and Home bring forth an issue of identity anxiety for those involved in the narrative: author, narrators, and readers. Featuring both first-person and third-person narrators, these works offer conflicting narratives in which the writer, Morrison, allows her characters to question her own authorial voice. Greater agency is given to the first-person narrators through which they deconstruct the traditional objectivity of third-person narratives. As such, this thesis argues, the structures of Love and Home extend their inside conversations to the real world of readers who must reconsider where their narrative trust has been. Moreover, Morrison’s challenge to her authorial voice becomes the means through which she questions the hegemony of U.S. historical narratives. In the end, it is the subjective voices of the first-person narrators which offer a more reliable, counter narrative of not only Morrison’s fictional stories, but that of the nation’s historical past.

Show moreCollegiate leadership development opportunities that enhance student’s leadership skills are on the rise. This study sought to understand how students perceive their own leadership development prior to entering college and at an institution that has prioritized leadership development in recent years. Through this single-case study, 51 undergraduate student leaders completed a questionnaire that resulted in a descriptive student leader profile and open-ended responses. From those 51 students, 14 were a part of focus groups. There were three focus groups in total with four, seven, and three participants respectively. From the 14 participants, five volunteered for individual interviews to identify their perceptions of their leadership development in their own words. The research questions for this study were: What are the inputs and environmental influences that shape college students’ leadership development output from the student perspective; and, how do college students describe and understand their leadership development? The descriptive profile and close-ended responses are reviewed in chapter four and report four major findings. The first finding was “Mom made me do it”: The Influence of Family and Experiences Precollege, and the second finding was The What and Who Behind These Students’ Leadership Development in College: Purposeful Experiences and People. The third finding was The Why Behind These College Students’ Engagement in Leadership Development, which encompassed four themes to describe the reasons these students’ are interested in leadership development: encouragement from others, aspirations, self-development, and motivation to support causes they have grown to want to serve and for which they want to develop. The fourth finding was Soft Skills - Not Clear in the Terminology of These Student Leaders, Clear in Their Behaviors and included ways of defining soft skills and the exemplification of student leaders’ soft skills. Conclusions and recommendations are offered in chapter six including the proposal of a new model, Closing the Loop in College, developed from the pattern of findings that emerged in this study inclusive of reflective meaning making in college as essential for these leaders’ development.

Show moreThe internal architecture of a beach system can provide clues into the processes involved in its formation, including depositional processes, and/or driving mechanisms (Billy et al., 2014). Several unique events such as cold fronts or Hurricane Irma caused conditions that resulted in erosion and accretion changes in Red Reef Beach - Boca Raton, throughout the year of 2017. Since the lateral extent of these changes is difficult to evaluate using traditional methods such as coring, a Ground Penetrating Radar (GPR) was tested, which allows for a good lateral resolution (cm scale), to image the distribution and evolution of these sediments. The objectives of this study were to 1) explore the lateral variability in the internal architecture of sediments in Red Reef beach in Boca Raton (FL) using an array of ground penetrating radar (GPR) measurements constrained with coring and sediment analysis; 2) explore how dynamics of erosion and accretion induced by changes in wave activity and related to tide variation and storm events, may affect surface topography and the sedimentary internal architecture of beach deposits, using RTK GPS and GPR time-lapse measurements; 3) to explore changes in the lateral extent of the freshsaltwater interface along the beach profile in relation to tide variation and storm events. Reflectors identified in the GPR images showed some evidence of erosional and accretionary surfaces preserved in Red Reef beach. These measurements were repeated over time coinciding with certain events (such as Hurricane Irma) to explore their effects in terms of sediment erosion and accretion as reflected in changes in topography (using time-lapse GPS-RTK measurements), and changes in the internal sedimentary architecture (using time-lapse GPR measurements). The datasets collected also revealed the temporal evolution of the salt-freshwater interface, showing how the lateral extent of saltwater saturated sediment (inferred from areas of GPR signal attenuation along the profiles) evolved over time. This study shows the potential of GPR to provide information about beach sediment processes and dynamics at resolutions beyond traditional measurements (such as coring). It also shows the importance of combining methods that are complementary, such as the use of RTK GPS to explore changes in topography, and GPR that provides information on subsurface sedimentary architecture and the mechanism of change such as post-storm recovery. This study has implications for better understanding changes in coastal sedimentary deposits and processes, both at the subsurface, particularly after high-energy events, such as hurricanes, that result in rapid changes in erosion and/or accretion of sediments.

Show moreThe purpose of this collective case study was to discover the decision-making processes used by senior student affairs officers when making wicked decisions related to the retention of specialized, at-risk student populations. Wicked decisions are complex, resistant to resolutions, lead to other problems, and are essentially unique. In this study, decisions related to retention of Black males; students with mental health issues; and lesbian, gay, bisexual, transgender, and queer student retention fall within the wicked problem category and were the focus of this study. These decisions are usually the responsibility of divisions of student affairs in higher education settings and the senior student affairs officer. Hence, the senior student affairs officer is tasked with making responsible and effective decisions that foster the success of all students. This dissertation focused on the decision-making processes, practices, and procedures student affairs officers use to support the retention of select special populations served in higher education.

Show moreThe majority of HIV prevalence is found in Sub-Saharan Africa with 36.9 mil- lion living with HIV/AIDS. The cultural implications such as patient non-compliance or denial of available routine medical care can potentially cause limitations on the ef- fectiveness of detecting such virulent pathogens and manage chronic disease. The lack of access to healthcare and further socioeconomic impacts hinder the ability to ade- quately diagnose and treat infection in resource-limited settings. Intervention through diagnosis and treatment helps prevent the spread of transmission, where pre-exposure prophylaxis or active disease prevention measures are not readily available. The cur- rent gold standard for HIV detection is by molecular detection; Reverse-Transcription Polymerase Chain Reaction is widely used that employs cycles of temperature condi- tions that require a thermal cycling platform and typically laboratory space for RNA extraction separate from RT-PCR space required. Serological detection can be ad- vantageous for surveillance and screening, Lateral Flow Assays and Enzyme-Linked Immunosorbent Assay (ELISA) can detect a viral protein (antigen) or antibodies. The ELISA can require at least 12 hours of assay preparation and takes a diagnostic laboratory many resources to run. There is need to develop Point-of-Care (POC) testing that can potentially be used for decentralized testing that can leverage ex- isting technologies such as smart phone capability and routine medical or diagnostic tests with cutting edge applications leveraging micro uidics, nanotechnology and in- tegrated circuit design. Such technologies allow for automated, rapid turnaround and cost-e ective diagnosis of HIV, where these assays could potentially be read- ily deployed. It is such technology that can potentially change the way diagnostics are performed, as POC technology can be rapidly disseminated, enable decentralized testing and, is user-friendly. A novel smart phone-enabled automated magnetic bead- based platform was developed for a micro uidic ELISA for HIV-1 detection at the POC to meet this demand.

- Abstract/Description
-

Show morePublic officials at the state level currently are called upon to create, evaluate, and implement policies that assess the effectiveness of teacher performance and hold teachers accountable for student achievement. Therefore, understanding the social construction of the teaching profession among those public officials is crucial to understanding the impact of the policy agenda on the work of teachers as well as being essential to exercising influence on the policy process itself. This study was an analysis of legislation regarding teacher accountability in an effort to provide insight into how the Florida State Legislature socially constructs the teaching profession. This study used a qualitative methodology to place teachers, as a group, in Schneider and Ingram’s (1993) typology of target populations and made use of historical analysis to trace the changes that have occurred in the social construction of teachers during the period from 1984-2015. In doing so, it found teachers are negatively constructed with a positive power component, correspondingly labeled contenders, on Schneider and Ingram’s typology. Ultimately, the effect of the pressures placed upon teachers has been to create projections of ongoing teacher shortages and to discourage potential candidates from pursuing the profession.

- Abstract/Description

Objects in a scene are likely to occlude other objects partially and are itself likely to be partially occluded. A central question, therefore, is how the visual system resolves the resulting surface correspondence problem by successfully determining which surfaces belong to which objects. To this end, a recently developed dynamic grouping methodology has determined whether pairs of adjacent surfaces are grouped (Hock & Nichols, 2012).

Show moreObjects in a scene are likely to occlude other objects partially and are itself likely to be partially occluded. A central question, therefore, is how the visual system resolves the resulting surface correspondence problem by successfully determining which surfaces belong to which objects. To this end, a recently developed dynamic grouping methodology has determined whether pairs of adjacent surfaces are grouped (Hock & Nichols, 2012). The grouping of adjacent surfaces, which depends on their affinity state, is indicated by the direction of perceived motion across one surface when its luminance is perturbed. In the current stimuli, which consists of a horizontal surface partially occluded by a vertical bar, dynamic grouping also can occur for nonadjacent surfaces, providing they are linked in two-dimensions by a connecting surface. Results indicate that the dynamic grouping motion is stronger for amodal completion entailing the perceptual grouping of nonadjacent surfaces behind an occluder.

The United States established the Environmental Protection Agency (EPA) to monitor and enforce compliance with environmental pollution standards through various programs and policies.

Show moreThe United States established the Environmental Protection Agency (EPA) to monitor and enforce compliance with environmental pollution standards through various programs and policies. One such policy, the Audit Policy, allows companies to voluntarily self-report violations to the Agency in exchange for elimination of certain penalties. Despite the policy, firms still incur large environmental penalties, thus indicating the need for better understanding of the policy. A necessary but not sufficient condition for penalty relief under the Audit Policy requires discovery of violations by an environmental audit or a compliance management system. This research explores the option of discovery by a compliance management system and examines the motivation of managers to invest in an environmental management system (EMS). The theory of reasoned action (TRA) argues that attitude and subjective norms precede intentions. I use this theory to investigate what factors cause a manager to invest in an environmental management system (EMS). Additionally, I examine whether environmental attitude, tolerance for ambiguity and willful blindness are antecedents to attitude towards an EMS. In this study, I develop and test a scale of the willful blindness construct and measure its impact on managerial decision-making. The willful blindness construct development produced a one-item measure. My results support all hypotheses except for the predicted link between tolerance for ambiguity and attitude.

Although temporal issues affecting organizations and leaders have been researched, time orientation (preference for one or more of the present, past, and future time frames) and visioning ability of change agents within organizations remain open for additional investigation.

Show moreAlthough temporal issues affecting organizations and leaders have been researched, time orientation (preference for one or more of the present, past, and future time frames) and visioning ability of change agents within organizations remain open for additional investigation. This exploratory survey study compared self-reported time orientation (TO) and visioning ability ratings of administrators and faculty at a community college. The research added to the extant literature by contextualizing the measures of the key constructs and extending the research to a novel setting. Scores for all three time frames were assessed in contrast to studies that emphasize future orientation. In addition, TO measures were obtained using an instrument constructed specifically for organizations (Fortunato & Furey, 2009). An adapted version of a visioning ability by Thoms and Blasko (1999) was constructed to address a specified time depth (the distant future) and domains relevant to higher education. Administrators reported significantly higher ratings than faculty on Future TO and visioning ability measures. Future TO scores for faculty were lower in relation to scores on the other two TO scales, but no within-group TO differences were found for administrators. A multiple regression model indicated that Future TO was the best predictor of visioning ability. Faculty teaching in the Associate of Science areas had higher Present TO scores than those teaching in the Associate of Arts programs. TO and visioning ability did not change as a function of gender, age, culture, and years of experience in higher education. The interpretation of the findings was limited by the lack of benchmarks that allow for meaningful comparisons across organizations, and by a continued need to establish construct and predictive validity for the key measures. The research has implications for hiring decisions, for staff development, and for temporal profiling in organizations interested in envisioning the distant future.

Show moreA quasi-experimental, between groups design was used to evaluate differences in emotional behavior, as measured by the Specific Affect Coding System (SPAFF), between professional therapists and their clients and a master therapist and his client. This coding system also was used to determine how emotional behavior shown by a master therapist changes over the course of six psychotherapy sessions. The research team recorded counseling sessions at a university counseling center in the southeastern United States and coded this video data using SPAFF in real time. Data were analyzed quantitatively to determine whether significant differences in SPAFF codes exist between the master therapist, professional therapists at the university counseling center, and their respective clients. Results indicated that the master therapist showed significantly more neutral and less negative affect than his counterparts at the university in both sessions one and four. The master therapist’s client showed significantly more neutral affect and less negative in session one and significantly more positive affect and less negative affect in session four.

Show moreCoral reefs on Florida’s Reef Tract (FRT) are susceptible to many anthropogenic influences including controlled freshwater discharges and agricultural runoff as well as high natural environmental variability from seasonal rainfall, runoff and upwelling. To better understand coral population structure and responses to sublethal stressors, populations of the scleractinian coral Montastraea cavernosa in the northern FRT were examined using a combination of genomic and transcriptomic techniques. Microsatellite genetic markers identified high local retention among sites and a slight southward gene flow. An in-situ temporal gene expression analysis utilizing a tag-based sequencing transcriptomic approach was used to analyze baseline coral health at St. Lucie Reef (SLR), off Stuart, FL. Temporal variation had the greatest influence of differential gene expression among M. cavernosa at SLR. Results will be shared with local resource managers and coupled with a complementary ex-situ experimental trial.
