Show moreThe purpose of this study was to examine the differences in sixth-, seventh-, and eighth-grade students' outcomes in relation to school configuration, specifically K-8 elementary schools as compared to 6-8 middle schools. Student outcomes focused on in this study were standardized test scores, number of out-of-school suspensions, and number of days absent. Race and gender served as moderator variables for all research questions.Quantitative data were obtained from a large central Florida school district and included 2016 Florida Standards Assessment scale scores in English Language Arts, Mathematics, and Algebra 1 End-of-Course Examinations, 2015 Florida Standards Assessment scale scores in English Language Arts and Mathematics for students in Grade 8 during the 2015-2016 academic year, 2013 and 2014 Florida Comprehensive Assessment Tests 2.0 Reading and Mathematics developmental scale scores for students in Grade 8 during the 2015-2016 academic year, number of out-of-school suspensions, and number of days absent by student for the 2015-2016 academic year. The data were analyzed via two-way analysis of variances to determine if statistically significant differences existed in student outcomes based on school configuration.The literature review supported the need to align the educational environment with student development in order to maximize student outcomes. In the quest to accomplish this, many districts have employed a number of school configurations, including the K-8 elementary school configuration and 6-8 middle school configuration to best meet the unique needs of early adolescents. The large central Florida school district selected for this study was unique in that it employed both the K-8 elementary school and 6-8 middle school configurations to serve students in Grades 6 through 8. As can be seen by results of this study, school configuration, either alone or in conjunction with one of the moderator variables, was indicated in differences in Grades 6 and 7 FSA ELA scale scores, Grades 6 and 7 FSA Mathematics scale scores, Grades 7 and 8 FSA Algebra 1 EOC Examination scale scores, FCAT 2.0 Reading growth, Grades 6, 7, and 8 number of OSS by student, and Grade 7 number of days absent by student. One of the most noteworthy findings of this study was differences in FSA ELA, Mathematics, and Algebra 1 EOC scale scores due to the interaction of school configuration and race. In general, students classified as Black had better FSA outcomes when attending schools of the 6-8 middle school configuration. In contrast, students classified as White or Other had better FSA outcomes when attending schools of the K-8 elementary school configuration. Such findings indicated that the K-8 elementary school configuration may be only a part of the puzzle when considering how to best educate students in the early adolescent developmental period.

Show moreMost people must commute to and from work each day, yet little research has examined this critical time between home and work and the potential spillover effects of commuting on employees' subsequent workplace behavior. Drawing on self-regulation theory and the commuting stress literature, I propose that stressful driving conditions on the way to work (e.g., bad weather, traffic congestion, long routes) can cause employees to subsequently behave unethically at work. Specifically, I suggest this occurs through a depletion of self-regulation as resources are consumed while driving under stress and thus unavailable for deterring tempting, unethical behavior. I test this mediation model in two studies using an experimental-causal-chain design. In Study 1, using a sample of 204 participants recruited at a university, I manipulated commuting conditions in a driving simulator and measured self-regulatory depletion and dishonesty using behavioral tasks in the laboratory. In Study 2, using an online panel of 117 participants, I manipulated self-regulatory depletion and measured dishonesty using modified versions of the same behavioral tasks. Overall I find some support that driving(-)regardless of driving-induced stress level(-)depletes self-regulatory resources and that reduced self-regulation leads to a higher likelihood to engage in unethical behavior.

Show moreAlthough a large body of research has attempted to answer the question, (")Is a happy worker a more productive worker?(") by examining the relationship between job attitudes and behaviors, results are often inconsistent. Drawing upon Fishbein and Ajzen's (1974) compatibility principle as well as theory on job attitude change and dynamic performance, the current study sought to answer this question by examining the attitudes-performance relationship at the within-persons level of analysis. Specifically, an Attitude-Engagement Model that specifies a broad conceptualization of job attitudes and behavioral engagement should exhibit the strongest relationship between job attitudes and job behaviors (Harrison, Newman, (&) Roth, 2006; Newman, Joseph, (&) Hulin, 2010) within-persons. Although relationships between these two domains have been theorized and examined within a between-subjects framework, no attempts have been made to examine these broad factors at the within-subjects level. Using experience sampling methodology (ESM), job attitudes and job behavior data were collected from 52 hairdressers, cosmetologists, and barbers across 1,438 observations. Using intensive longitudinal methods (Bolger (&) Laurenceau, 2013), evidence for large within-persons variability in both job attitudes and behavioral engagement was found. Evidence for the Attitude-Engagement model at the within-persons level of analysis was also provided, even after introducing a one (")moment(") and one (")day(") time lag. Furthermore, in order to provide evidence for the construct validity of the A-Factor and the E-Factor within-persons, evidence for the within-persons reliability of the assessment of change was established employing a generalizability framework. The findings have both research and practical implications for the study of attitudes and behaviors in the workplace and suggest several interesting avenues for future research.

Show moreMy three-paper dissertation is aimed at applying the concepts of bounded ethicality and ethical fading to accounting fraud. Typical of relatively new fields such as behavioral ethics, theoretical models are scarce (Tenbrunsel (&) Smith-Crowe, 2008). As such, the purpose of Study 1 is to unify disparate theories and ideas from psychology and behavioral ethics as a means of constructing a theory, the Theory of Unintended Amoral Behavior (TUAB), which includes the concepts of bounded ethicality and ethical fading. In addition, the pressure for management to meet earnings expectations is discussed through the lens of the TUAB as an example of how one may unknowingly misreport.Studies 2 and 3 apply the TUAB to investigate how certain contextual factors interact with egocentric biases to increase the likelihood of ethical fading. Specifically, Study 2 consists of an experiment exploring how inferior pay among managers interacts with egocentric perceptions of fairness and envy to affect the likelihood of one engaging in ethical fading and fraudulent behavior. Study 3 also utilizes an experimental methodology to examine how the pressure to meet earnings forecasts interacts with egocentric perceptions of fairness and negative affect to influence the probability of ethical fading and fraudulent acts.The results for Study 2 indicate that one who is paid at a lower rate is more likely to view this disparity as unfair, which leads to a greater feeling of envy. Although envy had no significant direct effect on ethical fading in the primary analyses, a supplemental analysis revealed that a person's risk preference might moderate this relationship. The primary findings of Study 2 suggest that individuals who experience a higher degree of ethical fading are more likely to commit fraud, and that ethical fading, along with perceived unfairness, seem to be significant psychological processes that explain how differences in pay may lead to fraud. The primary finding of Study 3 is that, like Study 2, fraud is more likely to occur as an individual experiences a higher degree of ethical fading. Furthermore, this study suggests that those who are closest to meeting an earnings target are the most likely to engage in fraudulent behavior. Finally, the results failed to find any support that one's egocentric perceptions of fairness and negative affect contribute towards his or her ethical behavior in a goal achievement setting. The primary contributions of this dissertation is that it unifies various theories and ideas from psychology and behavioral ethics to establish a testable theory (TUAB) that includes the concepts of bounded ethicality and ethical fading, serves as an initial test of TUAB, and provides evidence that unethical behavior is not necessarily the result of one consciously forsaking his or her ethics for some other desired goal (i.e., profit).

Show moreIn this dissertation, we address the problem of analyzing the activities of people in a variety of scenarios, this is commonly encountered in vision applications. The overarching goal is to devise new representations for the activities, in settings where individuals or a number of people may take a part in specific activities. Different types of activities can be performed by either an individual at the fine level or by several people constituting a crowd at the coarse level. We take into account the domain specific information for modeling these activities. The summary of the proposed solutions is presented in the following.The holistic description of videos is appealing for visual detection and classification tasks for several reasons including capturing the spatial relations between the scene components, simplicity, and performance [1, 2, 3]. First, we present a holistic (global) frequency spectrum based descriptor for representing the atomic actions performed by individuals such as: bench pressing, diving, hand waving, boxing, playing guitar, mixing, jumping, horse riding, hula hooping etc. We model and learn these individual actions for classifying complex user uploaded videos. Our method bypasses the detection of interest points, the extraction of local video descriptors and the quantization of local descriptors into a code book; it represents each video sequence as a single feature vector. This holistic feature vector is computed by applying a bank of 3-D spatio-temporal filters on the frequency spectrum of a video sequence; hence it integrates the information about the motion and scene structure. We tested our approach on two of the most challenging datasets, UCF50 [4] and HMDB51 [5], and obtained promising results which demonstrates the robustness and the discriminative power of our holistic video descriptor for classifying videos of various realistic actions.In the above approach, a holistic feature vector of a video clip is acquired by dividing the video into spatio-temporal blocks then concatenating the features of the individual blocks together. However, such a holistic representation blindly incorporates all the video regions regardless of their contribution in classification. Next, we present an approach which improves the performance of the holistic descriptors for activity recognition. In our novel method, we improve the holistic descriptors by discovering the discriminative video blocks. We measure the discriminativity of a block by examining its response to a pre-learned support vector machine model. In particular, a block is considered discriminative if it responds positively for positive training samples, and negatively for negative training samples. We pose the problem of finding the optimal blocks as a problem of selecting a sparse set of blocks, which maximizes the total classifier discriminativity. Through a detailed set of experiments on benchmark datasets [6, 7, 8, 9, 5, 10], we show that our method discovers the useful regions in the videos and eliminates the ones which are confusing for classification, which results in significant performance improvement over the state-of-the-art.In contrast to the scenes where an individual performs a primitive action, there may be scenes with several people, where crowd behaviors may take place. For these types of scenes the traditional approaches for recognition will not work due to severe occlusion and computational requirements. The number of videos is limited and the scenes are complicated, hence learning these behaviors is not feasible. For this problem, we present a novel approach, based on the optical flow in a video sequence, for identifying five specific and common crowd behaviors in visual scenes. In the algorithm, the scene is overlaid by a grid of particles, initializing a dynamical system which is derived from the optical flow. Numerical integration of the optical flow provides particle trajectories that represent the motion in the scene. Linearization of the dynamical system allows a simple and practical analysis and classification of the behavior through the Jacobian matrix. Essentially, the eigenvalues of this matrix are used to determine the dynamic stability of points in the flow and each type of stability corresponds to one of the five crowd behaviors. The identified crowd behaviors are (1) bottlenecks: where many pedestrians/vehicles from various points in the scene are entering through one narrow passage, (2) fountainheads: where many pedestrians/vehicles are emerging from a narrow passage only to separate in many directions, (3) lanes: where many pedestrians/vehicles are moving at the same speeds in the same direction, (4) arches or rings: where the collective motion is curved or circular, and (5) blocking: where there is a opposing motion and desired movement of groups of pedestrians is somehow prohibited. The implementation requires identifying a region of interest in the scene, and checking the eigenvalues of the Jacobian matrix in that region to determine the type of flow, that corresponds to various well-defined crowd behaviors. The eigenvalues are only considered in these regions of interest, consistent with the linear approximation and the implied behaviors. Since changes in eigenvalues can mean changes in stability, corresponding to changes in behavior, we can repeat the algorithm over clips of long video sequences to locate changes in behavior. This method was tested on over real videos representing crowd and traffic scenes.

Show moreThe primary aim of this study is to discover how leadership competencies affect the perceived effectiveness of crisis management. Leadership skills exhibited by public managers in crisis times may help eliminate panic and help victims recover from the difficult situation as soon as possible. The existence of effective leadership in a crisis is one of the most important inputs in order to diminish the harmful effects of crises and disasters. The absence of effective leadership in times of crisis may be one of the most significant problems in the public administration because it may result in loss of human life and property. By answering the following research questions this study provides useable knowledge for public managers and leaders during crises: Are there any different leadership features or characteristics for effective leadership at time of crises than the leadership in normal time? What is the role of effective leadership in managing crises and disasters (natural or man-made)? How do a public administrator's leadership traits and skills impact the effectiveness of crisis leadership? How do a public administrator's leadership behaviors (task-, people-, and organization-oriented behaviors) influence the effectiveness of a crisis leadership? With the aim of revealing these relations, a self-reported survey was sent to 2,095 current and former Turkish public security network managers. The study found that the core leadership competencies (decisiveness, flexibility, communication, problem solving, managing innovation and creativity, team building, managing and organizing personnel, motivating, networking and partnering, decision making, scanning the environment, and strategic planning) have a positive relationship with the effectiveness of crisis leadership. Among three categories of leadership behaviors, task-oriented leadership behaviors were found with the highest level of impact on the effectiveness of crisis leadership. The study indicated the importance of the core leadership competencies in the effectiveness of crisis leadership. According to the results, the hypothesis testing with the covariance structure model supported the positive impact of the core leadership competencies on the effectiveness of crisis leadership. This study contributes to the literature on leadership during crisis situations, and also provides proposals for public managers and practitioners in order to increase their effectiveness in leading their organizations during a crisis situation.

Show moreDoes the operational code of a state's leadership have an effect on its behavior during foreign policy crises? Specifically, do states with more conflictual operational codes opt for a more conflictual response to crises, or do systemic and structural variables intervene to limit their significance? While the study of individual level psychology in international relations has been gaining momentum, the causal links between beliefs and behavior have yet to be solidified. This study used ordered logistic regression across three models to determine the effect of the operational code on state crisis behavior while controlling for key domestic and crisis dimension variables. Predicted probabilities were also used to better demonstrate the variables' substantive effects. The 50 cases used in this research are drawn from the International Crisis Behavior Dataset composed by Brecher and Wilkenfeld, and they focus on the United States as the major crisis actor. Operational code data were derived from computer-based content analysis using the Verbs In Context System (Walker, Schafer, and Young 1998). The theoretical goal of this paper was to explain variance in state crisis behavior through variations in the operational codes of US Presidents. The results demonstrate that the operational codes of leaders do affect state crisis behavior. Specifically, the operational code indices P1 and I1 show that a leader with a more conflictual view of the nature of the political universe and a conflictual direction of strategy is more likely to employ escalatory crisis behavior.

Show moreDiversity in the United States is steadily increasing with racial and ethnic groups traditionally called minorities expected to account for over 50% of the U.S. population by 2050 (U.S. Census Projections, 2009). At the same time, the school age population is expected to consist of 60% students from (")minority(") backgrounds. Yet, school counselors are mostly from White, European backgrounds and are projected to continue to come from that background (Brown, Parham, (&) Yonker, 1996; Pack-Brown, 1999; Vaughn, 2007). This creates frequent cross-cultural counseling relationships within schools necessitating that school counselors have multicultural competence. Multicultural counseling competence (MCC) has been related to awareness of privilege (Mindrup, Spray, (&) Lamberghini-West, 2011). This research investigates that connection and the connection of self-reported MCC of school counselors to their multicultural school counseling behavior. The research also examines the connection with school climate, which has been connected in previous literature to academic achievement. This research indicates relationships between the self-reported MCC of school counselors and awareness of privilege and oppression. Results indicated a predictive relationship between MCC and awareness of privilege and oppression on multicultural school counseling behavior. Furthermore, results indicated a predictive relationship between MCC and awareness of privilege and oppression on perceived school climate. Results also indicate a relationship between reported multicultural school counseling behavior and perceived school climate. Selected demographic factors were also examined, indicating differences in the constructs of interest based on gender, ethnicity, and having taken a multicultural class. Relationships and differences remain after accounting for social desirability.

Show moreThis study examines the phenomena of (tele)presence in the distinct mediated environment of an online Christian worship service. A quantitative field experiment involving 48 participants who had just viewed a religious Internet broadcast was undertaken. Individual differences in personality and religiosity are examined in tandem with (tele)presence as predictors of a number of outcome variables, including memory, enjoyment of the online worship service and behavioral intention to be more active with the church. The results showed no significant relationship between religiosity and the experience of (tele)presence, but that users who experienced greater (tele)presence enjoyed the service more, had a greater ability to recognize information from the service, and had a greater intention to attend in the future. The implications for online worship services, along with the limitations of this study, are discussed.

Show moreA deficit currently exists in teacher preparation programs for teaching students with Autism Spectrum Disorder (ASD) using evidence-based practices, specifically in the area of Applied Behavior Analysis. As communication deficits are a primary characteristic associated with the diagnosis of ASD teaching communication skills is a common educational goal for students with ASD, and this skill needs to be addressed in teacher education. Mand training is one evidence-based practice applied to teach independent requesting skills to students with ASD.In this study, four teachers serving students with characteristics of ASD in the classroom participated in a multiple-probe across-participants study evaluating the extent to which online training videos prepare teachers in mand training procedures for students with ASD. Concurrent with teacher participants, changes in rates of student mands were evaluated for four students receiving instruction in a multiple probe design. Data analysis consisted of visual analysis of graphically displayed results and calculation of effect sizes. Results indicate that the Online Training Videos (OTV) were not effective as a standalone intervention for preparation of teachers to teach mands, however three student participants showed improved student outcomes.

Mid-career secondary school teachers (defined as having between 14-21 years of classroom experience) from Bayview Public Schools were selected to participate. A total of 152 mid-career secondary school teachers completed an electronic survey. Additionally, a total of 9 participants took part in one-on-one semi-structured interviews. The theoretical framework used to guide the study was the theory of planned behavior (TPB) (Ajzen, 1988; 1991) and Bandura's theory of self-efficacy (1977). The quantitative results from the electronic survey were used to augment qualitative data collected from interviews with willing participants.The interviews with study participants were analyzed for emerging themes. In all, a total of nine emerging themes came to light through the analysis of interview data. The data revealed areas of concern regarding the current method of evaluating teachers in Bayview Public Schools. A presentation of the findings with regard to the theoretical framework, literature, and practice were presented. Furthermore, a list of recommendations was provided addressing the specific concerns of participating teachers. In conclusion, recommendations were also made concerning future research that might continue to add to the body of knowledge concerning teacher evaluation.

Show morePhenotypic plasticity is the ability of the genotype to express alternative phenotypes in response to different environmental conditions and this is considered to be an adaptation in which a species can survive and persist in a rapidly changing environment. Some grasshoppers and locusts are capable of expressing an extreme form of density-dependent phenotypic plasticity, known as locust phase polyphenism. At low population density, the individuals typically have a cryptic coloration as nymphs, are less active, and only seek out conspecifics for reproductive purposes. At high density, however, they develop a drastically different phenotype in which they have a conspicuous coloration, are much more active, and tend to stay together in large groups. The American Birdwing grasshopper, Schistocerca americana, is a non-swarming species related to the desert locust, S. gregaria, which shows density-dependent phenotypic plasticity in behavior, color, and morphology. In this thesis, I have identified the duration of crowding necessary for a 6th instar S. americana reared in the isolated condition to express the typical crowded behavior. The behavior changed after just one hour of crowding and the effect of crowding diminished after 48 hours to near-complete isolated behavior. In reverse, the crowded condition was isolated, but behavior did not significantly change over time. Gene expression of the following three genes suspected of having a role in behavior change were investigated based on studies of S. gregaria: protein kinase A (PKA), L-Tryptophan-5-monooxygenase (T-5), and Aromatic L-amino acid decarboxylase (Decarb). T-5 was up-regulated in the long-term isolated condition compared to the long-term crowded condition. T-5 and Decarb were up-regulated in isolated individuals that were crowded for 10 hours compared to the long-term isolated condition. This study represents a novel contribution in the study of phenotypic plasticity as it establishes the time course of behavioral and molecular plasticity in a non-swarming grasshopper for the first time.

The research and application of Ultra-high Performance Concrete (UHPC) has been developedsignificantly within the last 1-2 decades. Due to the specific property of high strength capacity, it is potential to be used in bridge deck system without shear reinforcement so that it provides even lighter self-weight of the deck.

Show moreThe research and application of Ultra-high Performance Concrete (UHPC) has been developedsignificantly within the last 1-2 decades. Due to the specific property of high strength capacity, it is potential to be used in bridge deck system without shear reinforcement so that it provides even lighter self-weight of the deck. However, one of the shear component, dowel action, has not beenadequately investigated in the past. In this dissertation, a particular test was designed and carried out to fully investigate the dowel action response, especially its contribution to shear resistance. In addition, research on serviceability and fatigue behaviors were expanded as well to delete the concern on other factors that may influence the application to the deck system. Both experimental and analytical methods including finite element modeling, OpenSees modeling and other extension studies were presented throughout the entire dissertation where required.

Show moreThe determination of semantic equivalence is an undecidable problem; however, this dissertation shows that a reasonable approximation can be obtained using a combination of static and dynamic analysis. This study investigates the detection of functional duplicates, referred to as semantic method clones (SMCs), in Java code. My algorithm extends the input-output notion of observable behavior, used in related work [1, 2], to include the effects of the method. The latter property refers to the persistent changes to the heap, brought about by the execution of the method. To differentiate this from the typical input-output behavior used by other researchers, I have coined the term method IOE-Behavior; which means its input-output and effects behavior [3]. Two methods are defined as semantic method clones, if they have identical IOE-Behavior; that is, for the same inputs (actual parameters and initial heap state), they produce the same output (that is result- for non-void methods, and final heap state).The detection process consists of two static pre-filters used to identify candidate clone sets. This is followed by dynamic tests that actually run the candidate methods, to determine semantic equivalence. The first filter groups the methods by type. The second filter refines the output of the first, grouping methods by their effects. This algorithm is implemented in my tool JSCTracker, used to automate the SMC detection process. The algorithm and tool are validated using a case study comprising of 12 open source Java projects, from different application domains and ranging in size from 2 KLOC (thousand lines of code) to 300 KLOC. The objectives of the case study are posed as 4 research questions:1. Can method IOE-Behavior be used in SMC detection?2. What is the impact of the use of the pre-filters on the efficiency of the algorithm?3. How does the performance of method IOE-Behavior compare to using only input-output for identifying SMCs?4. How reliable are the results obtained when method IOE-Behavior is used in SMC detection? Responses to these questions are obtained by checking each software sample with JSCTracker and analyzing the results.The number of SMCs detected range from 0 45 with an average execution time of 8.5 seconds. The use of the two pre-filters reduces the number of methods that reach the dynamic test phase, by an average of 34%. The IOE-Behavior approach takes an average of 0.010 seconds per method while the input-output approach takes an average of 0.015 seconds. The former also identifies an average of 32% false positives, while the SMCs identified using input-output, have an average of 92% false positives. In terms of reliability, the IOE-Behavior method produces results with precision values of an average of 68% and recall value of 76% on average.These reliability values represent an improvement of over 37% (for precision) of the values in related work [4]. Thus, it is my conclusion that IOE-Behavior can be used to detect SMCs in Java code with reasonable reliability.

Show moreApproximately 47,700 pedestrians were killed between the years of 2000 - 2009. School buses are one of the safest modes of transportation (National Highway Traffic Safety Administration, 2004). However, the Central Florida school district eliminated bus transportation within the 2-mile radius from schools just last year. Children must prepare for an alternative mode of transportation; walking and biking. The purpose of this research was two-fold. First to develop an online safety training program for elementary school children; and second, a self-report questionnaire was constructed and piloted to measure how safety training and school infrastructure affects students' pedestrian risk-taking attitudes and risk perceptions to avoid the dangers of walking and biking to and from school. A 2x2 Factorial Multivariate Analysis of Variance (MANOVA) was used to test two categorical independent variables (safety awareness training, school infrastructure) for each of the two continuous dependent variables (pedestrian risk-taking attitudes and risk perceptions of pedestrian behavior). Using data from the pilot study, the researcher developed, self-reported questionnaires demonstrated that there was a significant difference between schools. Those receiving the training had lower mean scores in risk-taking attitudes than those who did not receive the training. Regardless of intervention, School 2 (complete infrastructure) takes fewer risks than School 1(incomplete infrastructure). The mean difference between groups was not statistically significant.

Show moreMany researchers have used the terms 'temperament' and 'personality' interchangeably when describing parents' behavioral styles. Although individual relationships among parents' temperament and personality, parenting behaviors, other parent characteristics, and young children's outcomes have been documented in the literature, parents' temperament and personality have not been examined collectively in conjunction with parenting and child outcome variables. As part of this study, 214 culturally diverse mothers with young children who ranged in age from 2- to 6-years rated their own temperament and personality, their parenting characteristics, and their young child's functioning (i.e., temperament and emotional and behavioral functioning). When examining mothers' temperament and personality together, factor analyses revealed a three-factor solution (i.e., General Life Approach, Rhythmicity, and Sticktoitiveness) and suggested that temperament and personality generally were separate but related constructs. Hierarchical and mediation regression analyses suggested the importance of examining both temperament and personality in the context of parenting behaviors and the outcomes experienced by young children. Overall, these findings suggested that mothers' temperament and personality play a significant role in parenting young children and optimizing young child outcomes. These findings are particularly helpful for professionals working with families experiencing difficulties dealing with their young child's difficult temperament styles as well as difficult emotional and behavioral functioning.

Show moreABSTRACT Extensive research has documented the relationship between listening to certain genres of music and negative effects on social behavior such as aggressive and antisocial behavior. The present study explored whether there are genres of music associated with altruism. Altruistic behavior is defined as behavior that is consistently more caring, helpful, considerate of other's feelings, and self- sacrificing. These behaviors promote our ability to thrive as a community. Yet, few studies have addressed the relationship between music and altruism. Data was collected from 608 college students who completed a self-report altruism scale, music preference measure, the Marlowe Crowne social desirability scale, and a demographic information form in order to see if there is a relationship between choice of music and altruism. A multiple hierarchal regression analysis found music genre choice accounted for 15.9 percent of variance in self-reported altruism. Significant, positive correlations emerged also between altruism and several music genres including alternative, country, classical, and emo.

Show morePolicing is more difficult than ever before in today's world since types of crime and criminal profiles change as a result of technological development and globalization. Police organizations should review their organizational and operational strategies to improve the fight against contemporary crimes and criminals. Behaviors and performance of police officers are very important in fighting crime. In this struggle, especially today, officers should exhibit organizational citizenship behaviors and perform better. One of the most important factors affecting these two concepts in organizations is organizational support. The literature stresses the social exchange cycle and reciprocity rules in the relationships of organizations and their members. In this cycle, if the organization cares about its members and if members perceive that the organization is supportive, they feel obliged to behave positively, perform better, and help the organization to reach its goals and objectives. If they don't perceive organizational support, they won't care about the organization, either. Hypotheses were developed based on these assumptions in the literature. This study tested these assumptions in Crime Scene Investigation units of the Turkish National Police (TNP). Structural Equation Modeling (SEM) was used to analyze the relationships among variables of Perceived Organizational Support (POS), Organizational Citizenship Behavior (OCB), and Perceived Performance (PP). Measurement models for these three latent constructs were developed by deriving the indicators from the literature. Most earlier studies tried to figure out reasons of the OCB. This study has a different perspective that investigates both reasons and results of OCB. A survey was developed to measure the latent variables of the study, and 405 of approximately 3,000 Crime Scene Investigators in the Turkish National Police responded to the iv survey. Results of the study showed that the relationship between POS and OCB is positive and significant. This is consistent with the literature. The relationship between OCB and PP is also positive and significant, and this is also consistent with the literature. However, the relationship between POS and PP is negative and insignificant. This result contradicts the results of previous studies in the literature and can be attributed to the subjective nature of measuring individuals' perceptions. According to the literature, perceptions are subjective rather than objective; therefore, data coming from reports of individual perceptions may not reflect the actual situation. Demographic information of the participants served as the control variables of the study. Information about the education level, rank, age, gender, size of the unit, and tenure of the respondents was collected by way of the conducted survey, and the effects of these variables were analyzed on the endogenous variable of the study, Perceived Performance. This study found no significant relationships between these control variables and Perceived Performance. Therefore, all these control variables were removed from the Structural Equation Model of the study. This study revealed that the TNP needs to be more supportive toward its members in order to have officers show organizational citizenship behavior and perform better. The TNP should revise its policies, especially regarding rotations from one province to another, working hours, rewards, and overtime pay. These are all indicators of organizational support and will result in a higher performance level among officers.

Show moreIn this dissertation, we address the problem of discovery and representation of group activity of humans and objects in a variety of scenarios, commonly encountered in vision applications. The overarching goal is to devise a discriminative representation of human motion in social settings, which captures a wide variety of human activities observable in video sequences. Such motion emerges from the collective behavior of individuals and their interactions and is a significant source of information typically employed for applications such as event detection, behavior recognition, and activity recognition. We present new representations of human group motion for static cameras, and propose algorithms for their application to variety of problems.We first propose a method to model and learn the scene activity of a crowd using Social Force Model for the first time in the computer vision community. We present a method to densely estimate the interaction forces between people in a crowd, observed by a static camera. Latent Dirichlet Allocation (LDA) is used to learn the model of the normal activities over extended periods of time. Randomly selected spatio-temporal volumes of interaction forces are used to learn the model of normal behavior of the scene. The model encodes the latent topics of social interaction forces in the scene for normal behaviors. We classify a short video sequence of $n$ frames as normal or abnormal by using the learnt model. Once a sequence of frames is classified as an abnormal, the regions of anomalies in the abnormal frames are localized using the magnitude of interaction forces.The representation and estimation framework proposed above, however, has a few limitations. This algorithm proposes to use a global estimation of the interaction forces within the crowd. It, therefore, is incapable of identifying different groups of objects based on motion or behavior in the scene. Although the algorithm is capable of learning the normal behavior and detects the abnormality, but it is incapable of capturing the dynamics of different behaviors.To overcome these limitations, we then propose a method based on the Lagrangian framework for fluid dynamics, by introducing a streakline representation of flow. Streaklines are traced in a fluid flow by injecting color material, such as smoke or dye, which is transported with the flow and used for visualization. In the context of computer vision, streaklines may be used in a similar way to transport information about a scene, and they are obtained by repeatedly initializing a fixed grid of particles at each frame, then moving both current and past particles using optical flow. Streaklines are the locus of points that connect particles which originated from the same initial position.This approach is advantageous over the previous representations in two aspects: first, its rich representation captures the dynamics of the crowd and changes in space and time in the scene where the optical flow representation is not enough, and second, this model is capable of discovering groups of similar behavior within a crowd scene by performing motion segmentation. We propose a method to distinguish different group behaviors such as divergent/convergent motion and lanes using this framework. Finally, we introduce flow potentials as a discriminative feature to recognize crowd behaviors in a scene. Results of extensive experiments are presented for multiple real life crowd sequences involving pedestrian and vehicular traffic.The proposed method exploits optical flow as the low level feature and performs integration and clustering to obtain coherent group motion patterns. However, we observe that in crowd video sequences, as well as a variety of other vision applications, the co-occurrence and inter-relation of motion patterns are the main characteristics of group behaviors. In other words, the group behavior of objects is a mixture of individual actions or behaviors in specific geometrical layout and temporal order.We, therefore, propose a new representation for group behaviors of humans using the inter-relation of motion patterns in a scene. The representation is based on bag of visual phrases of spatio-temporal visual words. We present a method to match the high-order spatial layout of visual words that preserve the geometry of the visual words under similarity transformations. To perform the experiments we collected a dataset of group choreography performances from the YouTube website. The dataset currently contains four categories of group dances.

Show moreWhat explains the difference between the county level vote received by President Donald Trump and U.S. Senator Marco Rubio in the 2016 Florida general election? Over the last couple of decades, Florida has earned a reputation for being a highly competitive state that impacts control of the White House and congress. As Florida's electorate becomes increasingly diverse, will the Democratic Party begin to win more often as their usual base grows, or will the Republican Party figure out a way to remain competitive? The 2016 general election presents an opportunity to analyze the structure of support for two Republican candidates who represent different paths for the future of the Republican Party: Trump, who won Florida by just one percent, and seemingly alienated Hispanics and women with his comments and policy proposals; or Rubio, who won by about eight percent, a Cuban-American thought to be a fresh voice for the GOP and a bridge to Hispanic voters. Regression analysis is used to examine support for Trump and Rubio and also the difference in support between the candidates. The results indicate Trump did better in counties with larger percentages of lower educated whites, lower income households, and higher unemployment rate. Rubio performed better than Trump in counties with larger numbers of Cuban and non-Cuban Hispanics, women, and voters not registered with either major party. These results suggest that Democrats may gain ground in Florida over time if the Trump wing of the GOP takes over the party and if current population trends continue.
