Title: CHARACTERISTICS OF RED LIGHT RUNNING CRASHESIN FLORIDA.
Creator: Elnashar, Dina, Radwan, Essam, University of Central Florida
Abstract / Description: Red light running is one of the main contributing factors of crashes in urban areas in Florida and the United States. Nationwide, according to preliminary estimates by the Federal Highway Administration (FHWA) 2001, there were nearly 218,000 red-light running crashes at intersections. These crashes resulted in as many as 181,000 injuries and 880 fatalities, and an economic loss estimated at $14 billion per year nationwide, According to the Community Traffic Safety Team Florida Coalition (A...
Show moreRed light running is one of the main contributing factors of crashes in urban areas in Florida and the United States. Nationwide, according to preliminary estimates by the Federal Highway Administration (FHWA) 2001, there were nearly 218,000 red-light running crashes at intersections. These crashes resulted in as many as 181,000 injuries and 880 fatalities, and an economic loss estimated at $14 billion per year nationwide, According to the Community Traffic Safety Team Florida Coalition (A statewide traffic safety group) there were 9,348 crashes involving red-light running in Florida and 127 fatalities in 1999. This research study focused on studying the red light running crashes and violations in the State of Florida. There were three primary objectives for this research. The first primary objective was to analyze the red light running crashes in Florida from 2002 to 2004. The data for this part was collected from the Crash Analysis Reporting System of the Florida Department of Transportation. These crashes are reported as "disregarded traffic signal" as far as the first contributing cause. The analysis focused on the influences of different factors on red light running crashes including the driver (age group, gender, and DUI history) and the environment (time of day, day of week, type of road, and weather). However, not all red light crashes are reported as "disregarded traffic signal". Therefore, representing red light running crashes only through "disregard traffic signal" noted reports would underestimate the extent of red light running effects at a given intersection. Therefore, the second objective was to review the long form crash reports to determine the actual number of crashes related to red light running. The analysis for a random sample of the crashes on the sate roads of Florida on the year 2004 showed that the percentage of crashes related to red light running reported on the database was found to be (3.13%), and the percentage of crashes related to red light running reported in the original crash repot filled by the police officer are much higher than reported(5.63%), which shows the importance of standardizing the format and coding process for the long form crashes conducted by the police officers to help accurately identify the real cause of the crash at the studied location. The third objective was to analyze the violations data given for five intersections and find if there is a correlation between the average rate of violations per hour and the frequency of red light running crashes. The analysis showed that utilizing the limited number of intersections used in the study, it appears that there is no correlation between the average violations per hour and the red light running crashes at the studied locations.

Show moreThis study evaluated the relationship between three different dimensions of sibling abuse(-) verbal, physical, and sexual(-) and communicative social adaptability and risk-taking outcomes. A quantitative survey (N = 477) explored the frequency of such abuse among college students and self-reported risk-taking behavior, social experience, social wit, appropriate self-disclosure, social confirmation, and social composure. Moreover, participants responded to nominal prompts asking whether they ever reported their sibling abuse. Independent sample t-tests and correlation tests show that survivors of sibling trauma are moee likely to appropriately disclose socially and are more likely to report engaging in an index of various risky behaviors (e.g. heavy drinking and suicidal ideation) during their life. The three dimensions of trauma are correlated with different dimensions of communicative social adaptability and risk-taking behaviors. With regard to communicative social adaptability, experiencing verbal abuse is correlated with an increase in social confirmation, appropriate social disclosure, and social wit while physical abuse is correlated with an increase in social confirmation and social wit. These results supplement a small but extant body of literature on sibling abuse and demonstrates the need to further study maladaptive sibling dyads.

Show moreThe research involved optimizing the space and bounding the output time by the output size in categorical range reporting of points within the given rectangle query Q in two dimension using wavelet trees and range counting. The time taken to report those points and space to tore n points in set S can be done using wavelet tree and range counting. Consider set S consisting of n points in two-dimension. An orthogonal range reporting query rectangle Q = [a,b] x [c,d] on set S is sent to report the set of points in S which interacts with the query rectangle[Q]. The time taken to report these points is dependent on the output size. The categorical range reporting is an extension of orthogonal range reporting, where each point (xi; yi) in S is associated with a category c[i] belongs to [sigma] and the query is to report the set of distinct categories within the query region [a,b] x [c,d] once. In this paper, we present a new solution for this problem using wavelet trees. The points in S associated with categories are stored in a wavelet tree structure. Wavelet tree structure consists of bit map for these categories. To report the categories in the given rectangle queryQ, rank and select operations on the wavelet tree is applied. It was observed that the space taken by the structure was O(n log sigma) space and query time is O(k log n log sigma). Notice that the new result is more efficient in space when log sigma = O(log n). The study provides a new and efficient way of storing large dataset and also bounds the time complexity by the output size k.

The research evaluates violations, which occurred while arrestees were assigned to GPS in 2009 and 2013; the programs first year and the most recent with complete data available. The results found limited factors that could be identified as predicting violations for those who violated the GPS, but the qualitative interviews shed much more light on the value of the program. The qualitative interviews were conducted with various stakeholders ranging from law enforcement to victim's advocates, and from state attorneys to public defenders. The overwhelming response rang loud, GPS allowed victims to feel safer and required more accountability on the part of the offender.

Show moreResearch shows that since the mid-1990s funders of the nonprofit sector have significantly increased the sophistication of their reporting requirements. Funders today want agencies to demonstrate beyond outputs and report on outcomes and the impact they have on the communities they serve. Funders are monitoring community impact by requiring more complex reports from the agencies they fund. These changes have meant that agencies must become proficient in data collection, management, and analyses practices in order to accurately respond to funders' report requests. Nonprofits, however, find these requirements difficult to conceptualize and even more difficult to attain. Managing and analyzing the data necessary to create the required reports proves a formidable task. This research shows that among many obstacles reported, a lack of communication between agency and funders about their intended goals leads to some frustration from both sides, ultimately making it exceptionally difficult to attain the ultimate goal of the new reporting requirements: to measure community-level impact. This study utilizes qualitative interviews with 8 human service nonprofit agencies and one funding agency in the greater Orlando area to investigate what agencies report are their major obstacles when trying to meet funders' new reporting requirements and what a funder's response to these concerns is. Agency interviews were analyzed for the most common themes and concerns reported. The interviews explore the way nonprofits are responding to the new requirements from donors and what they think could be done differently to better capture valuable data that would speak to issues at the community level.

Show moreTo date, the vast majority of research regarding personality in IO Psychology has relied on self-report assessments. Despite support for the utility of third-party assessments, IO Psychologists have only just begun extensive research in this area. Connelly and Ones (2010) conducted a meta-analysis that demonstrated that accuracy of third-party ratings improved as intimacy between the judge and the target grew. This remained true with the exception of predicting behavioral criteria, where non-intimates maintained superior predictability (Connelly (&) Ones, 2010). This was later contradicted by a recent investigation that found the best predictive validity for third-party assessments when they are taken from personal acquaintances as opposed to work colleagues (Connelly (&) Hulsheger, 2012). The current study is intended to investigate how the depth of the relationship and breadth of behavioral observations differentially moderate the relationship between third-party personality assessments and accuracy criteria (i.e., self-other overlap, discriminant validity and behavior). Results indicate that both depth and breadth impact accuracy criteria and they do so differentially based on trait visibility and evaluativeness. These findings will be discussed along with practical implications and limitations of the following research.

Show moreOver the past several years, increasing public emphasis on preventing child maltreatment has resulted in substantial changes to Florida's child abuse and neglect central registry. Many of these recent changes, aimed at preventing child maltreatment, have resulted in over one million false, unsubstantiated, and inconclusive reports of child abuse and neglect within the last decade. While the information held in reports may be useful for identifying and preventing potential child abuse or neglect, due process concerns have been raised with regards to the process of placing a person's name in a report without providing a hearing for challenging or removing inaccurate information. Focusing on Florida law, this research concentrates on: 1) the child maltreatment reporting process, 2) the procedures for maintaining reports, and 3) the accessibility of these reports in order to determine whether due process constitutional rights are protected under Florida's child abuse and neglect reporting laws. The intent of this thesis is to analyze the occurrence of unsubstantiated cases of child maltreatment, incidences of false reporting, and legal remedies available for those wrongfully accused of abusing or neglecting a child. Through the analysis of case law, federal and state statutes, available statistics, child abuse resources, and personal interviews with members of the Florida Legislature, evidence shows that due process constitutional rights are not protected under Florida's child abuse and neglect reporting laws. By raising awareness of the areas of child protection that require legal re-evaluation, this thesis aims to discover the balance between protecting children from harm and protecting adults from the severe ramifications resulting from false and improper allegations of child abuse and neglect.

Show moreMycobacterium tuberculosis (Mtb), the causative agent of tuberculosis, is a growing problem worldwide due to the emergence of multi-drug resistant and extensively-drug resistant strains of the bacteria. A key to combatting the spread of these strains lies in the understanding of gene expression occurring in Mtb. This study focuses on the development and optimization of a luciferase-based bioluminescent transcriptional reporter that can be used to monitor gene expression in Mtb. The luminescent signal emitted from the reporter can be measured and correlated with the level of transcription of certain genes. This study focuses specifically on a gene called whiB7 which encodes a transcription factor known to contribute to the drug resistance of Mtb. The drug-inducible whiB7 promoter was cloned into various locations in the luciferase plasmid in order to determine the ideal configuration of the reporter for maximum luminescence. The optimized luciferase reporter was then compared with a fluorescent transcriptional reporter, mCherry, also under control of the whiB7 promoter. Fluorescent reporters present some disadvantages including delayed kinetics and inability to accurately reflect gene downregulation due to long half-life of reporter proteins. It was hypothesized that the luciferase reporter would solve these problems by offering a more sensitive and dynamic tool to monitor gene expression. Quantitative real-time PCR was used to measure whiB7 mRNA present in cultures containing either the luciferase or mCherry reporters. The luminescent and fluorescent signal given from these reporters was then compared to actual mRNA expression. It was observed that the signal from the luciferase reporter more closely matched mRNA expression at each timepoint, indicating that the luciferase reporter is a better gauge of actual gene expression levels than the mCherry reporter.

Show morePresidents of Community Colleges and the administrators who reported directly to them were the subjects for this study based on the Four Frame Leadership Theory of Bolman and Deal (1990b). The Leadership Orientation (Self) Survey (LOS) was mailed to 169 community college presidents and administrators in the presidents' direct report teams. The final usable response rate of 69.82% to the survey fell within the acceptable range for education as defined by Boser and Green (1997). In addition, the subjects were asked to write about the most difficult challenge they had faced in their current position and how they handled that challenge. The purpose of this study was to determine (a) the usage of leadership frames from both groups; presidents and their administrative teams, (b) if gender or years of experience in their current positions were factors in leadership frame usage in each group, and (c) if there was a relationship between a president's frame usage and the frame usage of the members of the direct report team. The major findings were: 1. The presidents and administrators displayed the highest mean scores for the human resource frame with the mean scores of the three remaining frames (structural, political, and symbolic) clustering as a second unit of responses. In the narrative segment of the survey, the most frequently rated central theme among the presidents and the direct reports was the political frame. 2. The results from statistical analysis of the responses from both groups (presidents and the administrators who directly reported to them) did not show any statistically significant difference among frame use based on gender or number of years of experience in their positions. 3. The correlation coefficients did not indicate that there was a relationship in either direction regarding leadership style between the two groups (presidents and administrators). A phenomenological analysis of the scenario statements from these two groups indicated that presidents who used the political frame as a central theme tended to have administrators who also used the political frame as one or as a pair of central themes. Presidents who used the symbolic frame as a central theme tended to have administrators who used all four frames as central themes in their narratives. 4. A fourth finding was the discrepancy in the ability of the leaders to use multiple frames as demonstrated in the results from the quantitative and qualitative findings. The quantitative data suggested that these leaders were practicing the techniques of multi-framing more than one-half of the time. Contrary to this finding, the qualitative data showed that 5 of 30 scenario statements showed paired frames being used as central frames. 5. One additional finding based on the qualitative statements by presidents and their administrators revealed much thought and intentional practice in the leaders' ability to build teams.

Show moreThe relationship between positive health outcomes in persons with aphasia (PWA) and personcentered care is highlighted by personally relevant information obtained directly from the PWA. Such is often facilitated via patient reported outcome measures (PROMs). In order to provide accurate responses to PROMs, PWAs must to read, comprehend, formulate and generate answersto a variety of questions. PROMs designed for other clinical populations assessed/treated by speech-language pathologists have been found to be largely unreadable. Despite the significant role of PROMs in assessment and management of aphasia, no study to date has examined the readability of these measures. Four readability formulae were applied to identified PROMs for PWAs. These formulae estimate readability in terms of reading grade level and provide additional, quantitative information regarding textual elements such as syllable, word, and sentence length, complexity, and frequency. Fourteen PROMs were identified, per review of extant literature. A Macintosh-based readability software program was used to perform readability analyses. Additional metrics of clinical utility were applied to the selected measures via the Clinical Utility Scale. Results indicate that, on average, PROMs designed for PWAs are written at an eighth-grade reading level which is discordant with fourth-to-sixth reading gradelevel recommendations set forth by health literacy experts. Scores derived from the Clinical Utility Scale highlight the disconnect among measures that are easy to implement but are unreadable. Further analysis indicates that syllable-, word-, and sentence-level complexities can also impact the difficulty of analyzed texts. Results of the present study are consistent with prior PROM analyses performed across a variety of clinical populations assessed/treated by speech-language pathologists. Clinical implications and limitations of the present study are discussed as well as directions for further research.

Show moreThe purpose of this exploratory study was to analyze and examine the differences in the preparedness of educational institutions toward ensuring the security of their data by comparing their self-reported perceptions of security risks and their assessments of the corresponding risk-mitigating practices. Factors that were studied with reference to securing institutional data were aligned with the five components of information systems: hardware, software, data, procedures and people. The study examined the perceptions of security threats associated with these factors and explored the perceptions of the effectiveness of critical measures with respect to these factors within the constraints applicable to educational institutions. Given the dynamic nature of the threats to information security, this study further explored mechanisms and frequencies with which the different types of educational institutions conduct key security practices and stay up-to-date in their information security policies and procedures. The population of interest for this study consisted of a cross-sectional representation of the following types of educational institutions in the state of Florida: public and private PK-12 institutions, public and private universities, and virtual schools. At every stage of this exploratory study, comparative analyses were conducted. The researcher found no statistically significant differences between the types of educational institutions in their perceptions of security risks. However, in terms of their perceptions of the effectiveness of security measures, frequencies of key security practices and policy updates, budget allocations, and overall assessment of security preparedness, the educational institutions showed statistically significant differences.

Show moreThe third general standard of fieldwork requires auditors to maintain a skeptical mindset with regards to the collection and critical assessment of audit evidence. While professional skepticism is frequently referenced by professional standards, a lack of precision in defining the concept presumably leads to variation in how skepticism is exercised in practice. Drawing on theories from the fields of psychology, economics and organizational justice, this dissertation considers different perspectives of what constitutes sufficient professional skepticism and examines how those perspectives differ between audit practitioners and regulators.First, I consider competing perspectives of professional skepticism (-) neutral versus presumptive doubt (-) and whether asking auditors to adopt alternative perspectives of skepticism may have implications for audit efficiency and effectiveness. While, too little skepticism may endanger audit effectiveness and lead to audit failure or enforcement action, too much skepticism may arguably lead to unnecessary costs and inefficiency.Second, I consider whether the nature of the auditor-client relationship threatens an auditor's ability to maintain an attitude of professional skepticism. For example, theoretical perspectives from the fields of psychology and economics suggest that auditors may, consciously or unconsciously, be less skeptical of clients with whom they have developed close, positive working relationships or financial dependencies. More specifically, I consider whether skeptical behavior is impeded by management who display low-risk attitudes towards fraud or by client's who are considered to be highly important to the profitability of the local office.Finally, I examine how professional skepticism is defined from a regulator's perspective. When a public company is accused of fraudulent financial reporting, regulators may determinethat the audit performed on the fraudulent financial statements was deficient. Prior research has suggested that in such cases, insufficient skepticism is often a leading cause of alleged audit failure. Within a fairness theory framework, this study examines enforcement actions against auditors between 1999 and 2009, and identifies certain factors that are associated with a citation for a lack of professional skepticism. Overall, results suggest that regulators approach the issue by determining whether auditors should have been more skeptical. Factors found to affect this determination include whether the auditor was perceived as having been aware of an elevated risk of fraud or whether the client was accused of having provided the auditor with false or misleading information during the course of their investigation.

Show moreThe sleep characteristics of 37 military combat veterans (17 with PTSD and 20 without PTSD) of recent wars were analyzed to determine if combat deployment, with its resultant wartime sleep restriction, may be an alternative explanation for the sleep duration complaints found among combat veterans with PTSD (as determined by PCL-M scores). Participants completed sleep actigraphy and a self-report measure of sleep duration over a 1-week period. Although strongly correlated, a comparison of subjective (e.g., self-report) and objective (e.g., actigraphy) sleep duration revealed a significant difference in sleep duration based on method of assessment. With respect to group differences, actigraphy data did not reveal a significant difference in sleep duration based on the presence of PTSD, whereas there was a significant difference based on self-report. Veterans without PTSD self- reported a significantly longer sleep duration than what was recorded by actigraphy; a difference of one hour and 11 minutes (p = 0.000); the difference was one hour and nine minutes. In an effort to determine why veterans without PTSD perceived that they slept longer than they actually did, factors related to sleep quality were examined. The results indicated that measures of hyper arousal (anger, anxiety, nightmares) were significantly correlated with sleep duration, suggesting a pattern of autonomic arousal that is known to interfere with restful sleep. Further research is necessary to determine if the sleep of veteran with PTSD is actually different from that of combat veterans without PTSD, and if such differences are actually amenable to treatment for PTSD.

Show moreIn 2009, The United States Securities and Exchange Commission (SEC) issued a mandate requiring public companies to provide financial information to the SEC and on their corporate Web sites in an interactive data format using the eXtensible Business Reporting Language (XBRL). This dissertation consists of three separate, but interrelated studies exploring issues related to interactive data visualization in financial reporting contexts. The first study employs theories in information systems (task-technology fit and the technology-performance chain model) and cognitive psychology (cognitive load) to examine the link between characteristics of interactive data visualization and task requirements in a financial analysis context, and the impact of that link on task performance and user attitudes towards interactive data technology use. The second study extends the first by examining the effects of prior interactive data technology use on future choice to use an interactive technology. This study uses the IS continuance model to examine antecedents to continued interactive technology use based on previous assessments of task-technology fit and performance impacts from the first study. The third study employs an elaboration likelihood model (ELM) to understand the interactivity concept and its impact on information processing and belief/attitude formation. This study examines the impact of increasing interactivity on investor perceptions of forecast credibility and on a firm's attractiveness as a potential investment choice. Overall, these three studies provide insights on factors that impact decision-making in interactive financial reporting contexts, and how characteristics of interactive data visualization impact information processing, user perceptions, and task performance.

Show moreThis study investigated the relationship between religiosity of female college students and sexual victimization experiences. These experiences include the reporting behaviors that take place subsequent to an act of sexual victimization. The study utilized secondary data gathered from the forth wave of a longitudinal study funded by the National Institute of Justice between 1990 and 1995. The study used multidimensional levels of religiosity to analyze and to assess its impact on the sexual victimization experiences. Findings ascertained that certain behavioral measures of religiosity were consistently found to be a protective factor against sexual victimization. On the other hand, subjective measures of religiosity were not found to be a protective measure for victimization. Instead, this measure was statistically determined to be related to experiencing acts of sexual victimization. Recommendations were given for a greater focus on campus resources pertaining to student victimization and more in-depth research on the role churches have in dealing with this issue.

Show moreGiven the high number of errors and negative events committed within medical settings, the emphasis on patient safety culture is becoming more prevalent. Despite this effort, underreporting has been and continues to be an issue in this area. Some research has shown a link between underreporting and lack of management responsiveness, but more work is necessary to identify reasons for underreporting and potential mitigating solutions. The objective of the present research is to answer questions regarding the impact supervisors have on staff's patient safety perceptions and event reporting, through the use of archival survey data collected with the AHRQ Hospital Safety Culture Survey (2004). Probable moderators and mediators of key relationships were explored as well. Results are presented and their implications are discussed herein.

Show moreThe use of the periplasmic alkaline phosphatase (PhoA) reporter protein from E. coli has been critical for definition of the topology of transmembrane proteins of multiple bacterial species. This report demonstrates development of a PhoA reporter system in B. burgdorferi. Codon usage of the E. coli phoA in B. burgdorferi was analyzed and an optimized version of the gene was obtained. In order to assess the differential activity of the reporter system, two optimized PhoA-fusion construct using B. burgdorferi proteins were engineered: one using the periplasmic protein OppAIV and one using the cytoplasmic protein PncA. The activity of PhoA requires periplasmic localization. The periplasmic OppAIV-PhoA fusion as well as the cytoplasmic PncA-PhoA fusion produced detectable PhoA protein in E. coli and in B. burgdorferi. The periplasmic fusion construct, but not the cytoplasmic fusion construct, resulted in functional alkaline phosphatase (AP) activity in E. coli, as observed by blue colonies on agar plates containing a chromogenic substrate for AP. In contrast, both of the fusion constructs produced limited detectable levels of functional alkaline phosphatase activity in B. burgdorferi, as observed by yellow color change in liquid protein lysate containing a chromogenic substrate for AP. Development of a PhoA fusion reporter system for use in B. burgdorferi will provide a new molecular genetics tool for analyzing the topology of B. burgdorferi transmembrane proteins. These types of studies are critical for understanding the function of B. burgdorferi transport systems and may identify novel molecular approaches for the treatment of Lyme disease.

Show moreAccording to the Centers for Disease Control and Prevention (CDC), 8 million people each year are infected with Mycobacterium tuberculosis (Mtb) leading to 1.5 million deaths annually. This staggering number calls for advancements in understanding this bacterium so progress can be made in treating and preventing the disease. It is particularly important to understand mechanisms by which TB survives inside hostile host immune cells known as macrophages and within hypoxic granuloma lesions of the lung. Preliminary microarray data has shown that a TB gene known as Rv2633c is induced upon macrophage invasion. Bioinformatic analysis of Rv2633c coding sequence shows the product of Rv2633c has homology with hemerythrin-like proteins. Hemerythrins are a class of proteins commonly used to bind oxygen and sense nitric oxide and iron, leading us to hypothesize a role for Rv2633c in surviving hypoxic or nitrosative stress encountered within macrophages and granulomas. My first aim will be to generate a reporter strain of Mycobacterium smegmatis (Msm) expressing the mCherry fluorescent protein driven by the Rv2633c promoter. This tool will allow us to determine the stress conditions (i.e. hypoxia, nitric oxide treatment, acid pH) that activate expression of this gene by measuring the change in fluorescence. Linking the regulation of Rv2633c to specific environmental cues relevant to infections in vivo will provide insight into the role of this unique protein. Secondly, a knockout mutant of Rv2633c in the attenuated M. bovis BCG will be constructed and characterized to determine the importance and function of this protein during TB infections.

Show moreInsight into opportunities for process improvement provides a competitive advantage through increases in organizational effectiveness and innovation As a result, it is important to understand the conditions under which employees are willing to communicate this information. This study examined the relationship between trust and psychological safety on the willingness to report errors in a medical setting. Trust and psychological safety were measured at the team and leader level. In addition, the moderating effect of a learning orientation climate at three levels of the organization (i.e., team members, team leaders, organizational) was examined on the relationship between trust and psychological safety on willingness to report errors. Traditional surveys and social network analysis were employed to test the research hypotheses. Findings indicate that team trust, when examined using traditional surveys, is not significantly associated with informally reporting errors. However, when the social networks within the team were examined, evidence that team trust is associated with informally discussing errors was found. Results also indicate that trust in leadership is associated with informally discussing errors, especially severe errors. These findings were supported and expanded to include a willingness to report all severity of errors when social network data was explored. Psychological safety, whether within the team or fostered by leadership, was not found to be associated with a willingness to informally report errors. Finally, learning orientation was not found to be a moderating variable between trust and psychological safety on a willingness to report errors. Instead, organizational learning orientation was found to have a main effect on formally reporting errors to risk management and documenting errors in patient charts. Theoretical and practical implications of the study are offered.

Title: A Root Cause Analysis of the Barriers to Transparency among Physicians: A Systemic Perspective.

Show moreTransparency in healthcare relates to formally reporting medical errors and disclosing bad outcomes to patients and families. Unfortunately, most physicians are not in the habit of communicating transparently, as many studies have shown the existence of a large medical error information gap. Research also shows that creating a culture of transparency would mutually support patient safety and risk management goals by concomitantly reducing medical errors and alleviating the malpractice crisis. Three predictor variables are used to represent the various dimensions of the context just described. Perfectionism represents the intrapersonal domain, socio-organizational climate represents the interpersonal and institutional domains, and medico-legal environment represents the societal domain. Chin and Benne's normative re-educative strategy provides theoretical support for the notion that successful organizational change hinges upon addressing the structural and cultural barriers displayed by individuals and groups.The Physician Transparency Questionnaire was completed by 270 physicians who were drawn from a multi-site healthcare organization in Central Florida. Structural equation modeling was used to determine whether perfectionism, socio-organizational climate, and medico-legal environment significantly predict two transparency outcomes, namely, error reporting transparency and provider-patient transparency. Perfectionism and socio-organizational climate were found to be statistically significant predictors. Collectively, these variables accounted for nearly half of the variance in each transparency outcome. Within socio-organizational climate, policies had the greatest influence on transparency, followed by immunity and professional norms. Multiple group analysis showed that the covariance model developed in this study generalizes across gender, medical specialty, and occupation. In addition, group means comparisons tests revealed a number of interesting trends in error reporting and disclosure practices that provide insights about the behavioral and cognitive psychology behind transparent communication: 1) Physicians are more inclined to engage in provider-patient transparency compared to error reporting transparency, 2) physicians are more inclined to report serious errors compared to less serious errors, and 3) physicians are more inclined to express sympathy for bad outcomes than they are to apologize for a preventable error or be honest about the details surrounding bad outcomes. These results suggest that change efforts would need to be directed at medical education curricula and health provider organizations to ensure that current and future generations of physicians replace the pursuit for perfectionism with the pursuit for excellence. Also, a number of institutional changes are recommended, such as clearly communicating transparency policies and guidelines, promoting professional norms that encourage learning from mistakes rather than an aversion to error, and reassuring physicians that reporting and disclosure activities will not compromise their reputation. From the perspective of patient safety advocates and risk managers, the results are heartening because they emphasize a key principle in quality improvement - i.e., small changes can yield big results. From an ethical standpoint, this research suggests that healthcare organizations can inhibit (or facilitate) the emergence of professional virtues. Thus, although organizations cannot make a physician become virtuous, it is within their power to create conditions that encourage the physician to practice certain virtues. With respect to leadership styles, this research finds that bottom-up, grassroots change efforts can elicit professional virtues, and that culture change in healthcare lies beyond the scope of the medico-legal system.
