Show moreThis research investigates whether constructive criticism enhances creative performance within the relationship context of leaders and followers. Previous research on leadership and creativity defines creative products as novel and useful, but overlooks antecedents to creative action(-)the immediate precondition of creative products. Creative action, or creative performance, includes (1) identifying a problem, (2) searching for information, (3) generating solutions, and (4) evaluating the best solution. Previous research informs that three psychological mechanisms are responsible for creative actions: (1) sense-making, (2) motivation, and (3) knowledge processes. Constructive criticism is posited to act simultaneously on each of these processes to encourage creative performance across the creativity process. This relationship is hypothesized to be moderated by leader-member exchange. Furthermore, follower feedback-seeking behavior and learning goal orientation are also hypothesized to moderate the constructive criticism and creativity relationship. A series of moderated multiple regression analyses were conducted on survey data from 201 employees and 83 leader-follower dyads. Results indicate that constructive criticism has a null relationship with creativity, and may be detrimental to the in-role performance of followers. However, more nuanced analyses show that these relationships are to some degree moderated by leader-member exchange, the follower's learning goal orientation, and the follower's frequency of feedback seeking behavior.

Introduction: The widely-supported vascular depression hypothesis is underspecified with respect to cognitive mechanisms by which high cerebrovascular burden (CVB) and neuropathology relate to depressive symptoms. Integration of the vascular depression hypothesis with the CaR-FA-X model, a framework of affect regulation mechanisms, suggest that Rumination (R) and executive dysfunction (X) may increase due to altered recruitment of the dorsolateral prefrontal cortex resulting from high CVB and...
Show moreIntroduction: The widely-supported vascular depression hypothesis is underspecified with respect to cognitive mechanisms by which high cerebrovascular burden (CVB) and neuropathology relate to depressive symptoms. Integration of the vascular depression hypothesis with the CaR-FA-X model, a framework of affect regulation mechanisms, suggest that Rumination (R) and executive dysfunction (X) may increase due to altered recruitment of the dorsolateral prefrontal cortex resulting from high CVB and underlying neuropathology. This process would contribute to depressive symptomatology among older adults with high CVB. The progression of examined hypotheses included mediation models examining mechanistic relationships between predictors (CVB, DLPFC activation), cognitive correlates (rumination, executive functioning), and affective outcomes (depressive symptoms). Method: A sample of 52 community-dwelling, stroke-free, individuals over the age of 70, without history of severe mental illness, dementia, or severe cognitive impairment, completed the Ruminative Responses Scale, provided self-reported cerebrovascular burden data (cardiac disease, hypertension, diabetes, high cholesterol), and completed executive function tasks (Stroop, Flanker) while their hemodynamic response was measured using fNIRS. The Geriatric Depression Scale was used to assess depressive symptomatology. Prefrontal cortical recruitment was assessed using functional near-infrared spectroscopy (fNIRS).Results: A progression of conventional and bootstrapped regression-based models broadly supported relationships between CVB and depressive symptoms, but not between DLPFC activation and depressive symptoms. No mechanistic relationships were found, with respect to analyses testing prospective cognitive mediators.Conclusions: Primary findings from this study indicate that cerebrovascular burden predicts depressive symptomatology among older adults and is related to a reduction in inhibitory control ability. Further, these findings inform CVB measurement and mental health implications of contrasting approaches to CVB measurement. A primary contribution of this thesis is that results appear to support utilization of fNIRS, a low-cost and accessible neuroimaging paradigm, for the study of lateralized cognition among older adults.

Show moreABSTRACTResearch in socio-historical studies of literacy have focused on the social and historical aspects of literacy. While these prior studies have illuminated how we think about the social and historical context surrounding literacy, we have not studied women's literacies in relation to the economy as much. In response, this study focuses particularly on women's literacies during a specific time period, that of the 1960s to the 1990s, which ushered in second wave feminism's fight for equality in the workplace and the change from traditional capitalism to (")fast(") or (")new(") capitalism. To develop this inquiry, and find out about women's literacies during this historic intersection, I drew from Brandt and Berteaux's life history interview method paired with Charmaz's grounded theory to conduct literacy history interviews with seven women of varying occupations. All the participants started their working lives between 1960 and 1966 and continued to work at least through the 1990s. Findings show that women used their literacies to document in our society, which demanded increasing documentation, in order to get and keep positions of authority. Some women used a keen sense of audience awareness and ethos to gain the authority to write their own work beyond documentation. These women are the boundary breakers who succeeded in occupations previously dominated by men. The participants' literacies are complicated, however, and it was interesting to find that their education levels did not always match their economic levels. Two of the participants achieved upper echelon positions and earned more than most of the others despite not having degrees. Graff's, (")The Literacy Myth("), helps explain this paradox, but my research adds an additional contour to his theory by looking at how women used literacies gathered from various sources to gain authority in a documentary workplace. While researchers like Brandt and Graff have done global literacy studies, this study hones in on the complications and particularities of women's literacies during the convergence of two socio-historic trends, feminism and fast capitalism. This study highlights how women used their literacies in a documentary society to gain authority in the workplace. This research also sheds light on the part literacy played in women's ability to succeed in professions previously dominated by men. Understanding the results of this study could help us better understand the paradoxes of women's literacies and work as well as how women have managed these paradoxes when possible. Most importantly, this research sheds light on literacies in our fast capitalist, documentary society, which is a defining feature of our contemporary moment.

Show moreConcerns about K-12 students' mental health and social, emotional, and ethical development have prompted some schools to implement programs designed to promote student well-being and healthy social and emotional functioning. Most of these programs are distinguished as social and emotional learning (SEL) programs and/or character education programs. Although there is growing empirical support for the potential of school-based mindfulness interventions to positively influence students' well-being, the number of school-based mindfulness studies is limited, and the majority of the investigations have focused on students' cognitive rather than affective capacities. Loving-Kindness Meditation (LKM), a mindfulness- and compassion-based practice, is garnering recent attention as an effective intervention for positively affecting numerous factors related to well-being. For instance, research has demonstrated LKM's effectiveness in enhancing positive emotions, empathy, and social connectedness, and improving problem behaviors in adult populations. Although LKM is a component of the Mindfulness-Based Stress Reduction (MBSR) program, and a number of mindfulness-based school programs are MBSR- adapted, to date LKM has not been studied with children or youth populations. With this in mind, the purpose of this active comparison trial investigation was to examine the effects of a loving-kindness meditation intervention on positive emotions, empathy, social connection, and problem behaviors in second- and third- grade students. Findings suggest LKM may be more appropriately used in school settings as a sequential part of a comprehensive mindfulness program and introduced after a solid mindfulness practice has been established.

Wellness is an integral component of the helping professions (Myers (&) Sweeney, 2005; Witmer, 1985). Specifically, wellness is included in ethical codes, suggestions for practice, and codes of conduct throughout counseling, psychology, and social work fields (see American Counseling Association Code of Ethics, 2014; American Psychological Association Ethical Principles of Psychologists and Code of Conduct, 2010; National Association of Social Workers Code of Ethics, 1996).

Show moreWellness is an integral component of the helping professions (Myers (&) Sweeney, 2005; Witmer, 1985). Specifically, wellness is included in ethical codes, suggestions for practice, and codes of conduct throughout counseling, psychology, and social work fields (see American Counseling Association Code of Ethics, 2014; American Psychological Association Ethical Principles of Psychologists and Code of Conduct, 2010; National Association of Social Workers Code of Ethics, 1996). Even so, wellness in helping professionals is a difficult construct to measure. Thus, the purpose of the research investigation was to develop the Helping Professional Wellness Discrepancy Scale (HPWDS) and examine the psychometric features of the HPWDS in a sample of helping professionals and helping professionals-in-training. A correlational research design was employed for this investigation (Gall, Gall, (&) Borg, 2007). Specifically, the researcher examined: (a) the factor structure of the HPWDS with a sample of helping professionals; (b) the internal consistency reliability of the HPWDS; (c) the relationship between HPWDS scores and Counseling Burnout Inventory (CBI) scores; (d) the relationships between helping professionals' HPWDS scores and their reported demographic data; and (e) the relationship between HPWDS factor scores and the Marlowe-Crowne Social Desirability Scale-X1 (MCSDS-X1). The research questions were examined using: (a) Factor Analysis (FA), (b) Cronbach's alpha, (c) Spearman Rho correlation, (d) Multiple Linear Regression (MLR) and (e) internal replication analysis. A review of the literature is provided, discussing theoretical and empirical support for all the items on the initial model of the HPWDS (n = 92) as well as for all the items included on the final HPWDS exploratory model (n = 22). The researcher investigated helping professionals' perceived levels of wellness, aspirational levels of wellness, and the discrepancy between perceived and aspirational levels of wellness. The data was collected via online, mail out, and face-to-face administration to increase methodological rigor. The sample size for the investigation was 657, with 88 coming from Face-to-Face sampling, 87 from mail out sampling, and 484 from online/email sampling. Data analysis resulted in a five-factor exploratory HPWDS model that accounted for 69.169% of the total variance. Model communalities were considered acceptable with only three communalities below the recommended .5 value. Factor 1 represented Professional (&) Personal Development Activities and accounted for 32.605% of the variance, Factor 2 represented Religion/Spirituality and accounts for 13.151% of the variance, Factor 3 represented Leisure Activities and accounted for 9.443% of the variance, Factor 4 represented Burnout and accounted for 7.198% of the variance, and Factor 5 represented Helping Professional Optimism and accounted for 6.773% of the variance. In addition to a literature review, the research methodology and research results are provided. Results of the research investigation are discussed and areas for future research, limitations of the study, and implications for the helping professions are presented. Some implications of the findings include: (a) a theoretically and methodologically sound instrument for assessing wellness discrepancies in helping professionals is important; (b) helping professionals should be aware of both the personal and professional activities they are engaging in to increase their knowledge and self-efficacy, as well as their leisure activity engagement; (c) it is advantageous for researchers to use the scale development procedures, rigorous sampling methodologies, and FA guidelines outlined throughout Chapters 3 and 4 when developing new assessments for evaluating helping professionals; and (d) a five factor wellness assessment allowing helping professionals to evaluate themselves in Professional (&) Personal Development Activities, Religion/Spirituality, Helping Professional Optimism, Leisure Activities, and Burnout arenas is integral in assessing wellness discrepancies in helping professionals.

Show moreReading comprehension deficits in children with ADHD are well-established; however, limited information exists concerning the cognitive mechanisms that contribute to these deficits and the extent to which they interact with one another. The current study examines two broad cognitive processes known to be involved in children's reading comprehension abilities(-)(a) working memory (i.e., central executive processes [CE], phonological short-term memory [PH STM], and visuospatial short-term memory [VS STM]) and (b) orthographic conversion(-)to elucidate their unique and interactive contribution to ADHD-related reading comprehension deficits. Thirty-one children with ADHD and 30 typically developing (TD) children aged 8 to 12 years (M = 9.64, SD = 1.22) were administered multiple counterbalanced tasks assessing WM and orthographic conversion processes. Relative to TD children, children with ADHD exhibited significant deficits in PH STM (d = -0.66), VS STM (d = -0.84), CE (d = -1.24) and orthographic conversion (d = -0.85). Bias-corrected, bootstrapped mediation analyses revealed that CE and orthographic conversion processes modeled separately, partially mediated ADHD-related reading comprehension impairments, whereas PH STM and VS STM did not. CE and orthographic conversion modeled jointly fully mediated ADHD-related reading comprehension deficits wherein orthographic conversion's large magnitude influence on reading comprehension occurred indirectly through CE's impact on the orthographic system. The findings suggest that adaptive cognitive interventions designed to improve reading-related outcomes in children with ADHD may benefit by including modules that train CE and orthographic conversion processes independently and interactively.

Kidron Road and Other Stories is a collection of fiction that ranges from the soberly tragic to the magically real. The characters in each selection are molded by their choices, the choices of others, and the cruel whims of fate. I am fascinated by the way fatalism and free will intersect in the human experience. Therefore, my work often explores the paradoxical way lives are molded by past decisions while, at the same time, those decisions seem determined by outside forces.

Show moreExcessive gross motor activity is currently considered a ubiquitous and disruptive feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between activity level, attention, and working memory. The current study investigated whether, and the extent to which, particular forms of gross motor activity are functionally related to children's attention and phonological working memory performance. Objective observations of children's gross motor movements and attention by independent observers were conducted while children with ADHD (n = 29) and typically developing children (n = 23) completed multiple counterbalanced tasks entailing low and high phonological working memory demand. The tasks were then sequenced hierarchically to reflect the lowest to highest activity level condition for each child. Results revealed that (a) ADHD-related phonological working memory performance deficits are moderated by increases in intra-individual activity level, (b) heightened activity level impacts performance independently of changes in observed attention, and (c) increases in particular forms of movement (foot movement and out-of-chair movement) contribute to greater phonological working memory performance within the context of attentive behavior. The findings collectively indicate that phonological working memory deficits in children with ADHD are associated with an inability to up-regulate motor activity to facilitate optimal task performance, and that behavioral treatments targeting reductions in certain forms of hyperactivity may have unintended consequences on working memory functioning in ADHD.

Show moreThe present study examined the social skills and social acceptance of children with SAD (n=20), children with GAD (n=18), and typically developing (TD) children (n=20). A multimodal assessment paradigm was employed to address three study objectives: (a) to determine whether social skills deficits are unique to children with SAD or extend to children with GAD, (b) to assess whether skills vary as a function of social context (in vivo peer interaction Wii Task versus hypothetical Social Vignette Task) and (c) to examine the relationship between anxiety diagnosis and social acceptance. Parent questionnaire data indicated that both youth with SAD and GAD experienced difficulties with assertiveness, whereas children with SAD experienced a broader range of social skills difficulties. Blinded observers' ratings during the behavioral assessment social tasks indicated that compared to children with GAD and TD children, children with SAD have deficits in social behaviors and social knowledge across settings, including speech latency, a paucity of speech, few spontaneous comments, questions and exclamations, and ineffective social responses. In addition, vocal analysis revealed that children with SAD were characterized by anxious speech patterns. By comparison, children with GAD exhibited non-anxious speech patterns and did not differ significantly from TD youth on social behaviors, with the exception of fewer spontaneous comments and questions. Lastly, children with SAD were perceived as less likeable and less socially desirable by their peers than both children with GAD and TD children. Clinical implications of these findings are discussed.

Show moreThe first semester of practicum is a difficult time for counseling students as they learn to integrate knowledge and theory into clinical practice, often evoking high levels of anxiety (Barbee, Scherer, (&) Combs, 2003; Ronnestad (&) Skovholt, 1993) and limiting counselor self-efficacy (Bernard (&) Goodyear, 2009; Melchert et al., 1996). Practicum is the first opportunity counselors-in-training have to apply theoretical knowledge in a professional setting, use new clinical skills, and test how well they fit into the field of counseling (O'Connell (&) Smith, 2005). Additionally, if counselor educators do not fully understand the process counselors in training develop counselor self-efficacy, they may be overlooking opportunities to educate a new generation of counselors or using their time, energy and resources in areas that may not be the most efficient in counselor development. The purpose of this study was to examine the effect of an embedded, rich-media distributed learning environment added to practicum had on the development of counselor self-efficacy, reduction of anxiety and effect on treatment outcomes for counselors in training in their first semester of practicum. This study found the use of distributed learning to extend education beyond the classroom significantly and positively affected the development of counselor self-efficacy, had mixed statistical results on the reduction of anxiety and did not have an affect on treatment outcome. Furthermore, the study used hierarchical linear modeling to see if the characteristics of individual practicums affected the three main constructs, the results did not find a significant effect from the groups.The results of the study produced several implications for counseling. First, if counselor educators help counselors in training become more aware of counselor self-efficacy, the students can better understand how the construct affects their anxiety, their comfort with expanding or improving their clinical skills and the approach they take to a client, session or treatment plan. A second implication is that using an embedded, rich-media learning environment may help the counselors in training to develop their clinical skills. The results of this study imply that utilizing technology and discussions beyond the classroom is beneficial for (a) increasing the students' counselor self-efficacy, (b) normalizing the emotions the students may experience and (c) improving the methods for development through vicarious learning. Also, as technology continues to evolve and as education continues to adapt by integrating technology into the classrooms, counselor educators should begin exploring how to best use technology to teach students during practicum. Traditionally, based on the nature of counseling, practicum has been an interpersonal experience, but the results of the current study imply the methods of extending learning beyond the traditional class time is beneficial. Finally, as counselor educators strive to increase students' counselor self-efficacy early in practicum, in an environment that contains anxiety and self-doubt (Bernard (&) Goodyear, 2009; Cashwell (&) Dooley, 2001) using vicarious learning through video and online discussions can assist in accomplishing the goal.

Show moreThe design of high-performance computing architectures requires performance analysis of large-scale parallel applications to derive various parameters concerning hardware design and software development. The process of performance analysis and benchmarking an application can be done in several ways with varying degrees of fidelity. One of the most cost-effective ways is to do a coarse-grained study of large-scale parallel applications through the use of program skeletons. The concept of a ``program skeleton'' that we discuss in this paper is an abstracted program that is derived from a larger program where source code that is determined to be irrelevant is removed for the purposes of the skeleton. In this work, we develop a semi-automatic approach for extracting program skeletons based on compiler program analysis. We demonstrate correctness of our skeleton extraction process by comparing details from communication traces, as well as show the performance speedup of using skeletons by running simulations in the SST/macro simulator. Extracting such a program skeleton from a large-scale parallel program requires a substantial amount of manual effort and often introduces human errors. We outline a semi-automatic approach for extracting program skeletons from large-scale parallel applications that reduces cost and eliminates errors inherent in manual approaches. Our skeleton generation approach is based on the use of the extensible and open-source ROSE compiler infrastructure that allows us to perform flow and dependency analysis on larger programs in order to determine what code can be removed from the program to generate a skeleton.

Show moreThis research examines the use of writing resources in tutoring sessions, which is considered one of the valued tutoring practices at the University Writing Center (UWC) at the University of Central Florida (UCF). This research explains the methodology and presents the findings of a study that serves as a partial answer to the call for more evidence-based research in the field of writing center studies. There is scholarship that explains the importance of using resources to facilitate learning, but there is a lack of empirical research that explores the patterns and variations in the resources that writing tutors use, the ways they are implemented in tutoring sessions, and the effects of the moves tutors and writers make involving resources.To address this gap in the research, the researcher developed a study of tutoring sessions in the UCF UWC to explore the role of writing resources as they are used to mediate activity in tutoring sessions. This research investigates the relationship between the use of resources by the tutor and/or the writer and the impact this has on the facilitation of the writer's learning during the consultation. To gain insight into these areas of interest, tutoring sessions were video recorded and follow-up interviews were conducted with the participants to gain insight into the choices made involving resources and the resultant consequences. This research demonstrates the potential of writing resources to contribute to the collaborative knowledge development processes that happen in tutoring sessions to address writing concerns. This study also provides insight into the control that tutors have over the distribution of knowledge in the way that they implement resources into the tutoring session. What we can learn from these findings is a step toward developing a more evidence-based practice in the writing center.

While prior research has revealed the cognitive complexity of such work, there is still a gap in research investigating the literacy practices of (")blue-collar(") workplaces. Through the lenses of New Literacy Studies and activity theory, this case study examines the texts used in a room remodel, the literacy practices surrounding the texts, and the sociocultural implications of these practices. Through document-based and retrospective interviews, the primary participant is given a voice in identifying and describing the practices and values associated with the texts in his workplace. Literacies identified during interviews are examined in context through observations. The findings indicate the importance of texts not just for facilitating the renovation work, but for developing the social relationships necessary for working together. Influenced by the work of Brandt and Clinton, this study looks beyond the limits of the local to examine how the literacy practices of home renovation workers shape and are shaped by globalizing forces. By situating home renovation work within the larger network of the Information Age, this study questions the extent to which new workplace literacies are blurring the line between knowledge work and manual labor.

Auditory preemption theory suggests two competing assumptions for the attention-capturing and performance-altering properties of auditory tasks. In onset preemption, attention is immediately diverted to the auditory channel. Strategic preemption involves a decision process in which the operator maintains focus on more complex auditory messages. The limitation in this process is that the human auditory, or echoic, memory store has a limit of 2 to 5 seconds, after which the message must be...
Show moreAuditory preemption theory suggests two competing assumptions for the attention-capturing and performance-altering properties of auditory tasks. In onset preemption, attention is immediately diverted to the auditory channel. Strategic preemption involves a decision process in which the operator maintains focus on more complex auditory messages. The limitation in this process is that the human auditory, or echoic, memory store has a limit of 2 to 5 seconds, after which the message must be processed or it decays. In contrast, multiple resource theory suggests that visual and auditory tasks may be efficiently time-shared because two different pools of cognitive resources are used. Previous research regarding these competing assumptions has been limited and equivocal. Thus, the current research focused on systematically examining the effects of complexity and timing of communication interruptions on visual detection tasks. It was hypothesized that both timing and complexity levels would impact detection performance in a multi-task environment. Study 1 evaluated the impact of complexity and timing of communications occurring before malfunctions in an ongoing visual detection task. Twenty-four participants were required to complete each of the eight timing blocks that included simple or complex communications occurring simultaneously, and at 2, 5, or 8 seconds before detection events. For simple communications, participants repeated three pre-recorded words. However, for complex communications, they generated three words beginning with the same last letter of a word prompt. Results indicated that complex communications at two seconds or less occurring before a visual detection event significantly impacted response time with a 1.3 to 1.6 second delay compared to all the other timings. Detection accuracy for complex communication tasks under the simultaneous condition was significantly degraded compared to simple communications at five seconds or more prior to the task. This resulted in a 20% decline in detection accuracy. Additionally, participants' workload ratings for complex communications were significantly higher than simple communications. Study 2 examined the timing of communications occurring at the corresponding seconds after the visual detection event. Twenty-four participants were randomly assigned to the communication complexity and timing blocks as in study 1. The results did not find significant performance effects of timing or complexity of communications on detection performance. However the workload ratings for the 2 and 5 second complex communication presentations were higher compared to the same simple communication conditions. Overall, these findings support the strategic preemption assumption for well-defined, complex communications. The onset preemption assumption for simple communications was not supported. These results also suggest that the boundaries of the multiple resource theory assumption may exist up to the limits of the echoic memory store. Figures of merit for task performance under the varying levels of timing and complexity are presented. Several theoretical and practical implications are discussed.

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 moreDoes a leader's psychology affect his/her likelihood of initiating a militarized interstate dispute? The study of leadership psychology has continuously found support for the central assumption that leaders matter in explaining a state's foreign policy behavior. However, many of these research projects have relied on small-sample case studies and experimental methods that have limited generalizability. In this paper, I use two variables drawn from the research program on leadership trait analysis (distrust and need for power) in a multivariate large-n study to explain the initiation of militarized interstate disputes (MIDs). 1,601 cases are drawn from the Correlates of War MID data set. First, using an ANOVA model, I demonstrate that MID initiators have higher average scores for both distrust and need for power and that this difference is statistically significant. Then, using logistic regression, I demonstrate that distrust and need for power have statistically significant positive effects on the likelihood of MID initiation. I conclude by comparing the predicted probabilities of the psychological variables of interest with territorial contiguity. All of these methods demonstrate that the psychological traits of leaders have an important effect on the likelihood of MID initiation.

Show moreDoes a state leader's psychology influence lethality in civil wars? This thesis analyzes the aforementioned question during post-1945 civil wars. This particular subject, paying close attention to individual psychology at the state level, is gaining traction amongst scholars, though limited scholarly attention has addressed whether leader psychology is an indicator of conflict severity in terms of lethality. The psychology of the state leader in this thesis is assessed from leadership traits and operational code indices, specifically direction of strategy (I1) and interpretation of the nature of the political universe (P1). The data and cases used are pulled from datasets by Dr. James Fearon and the Correlates of War Project. The leaders' speech content is derived primarily from prepared material and analyzed using verbal content analysis via Profiler Plus. In measuring the effects of the predictors on my dependent variable, I chose the methodological approach of count data models, specifically, zero-truncated negative binomial regression. The results from the eight models I ran show that specific psychological traits, particularly a leader's I1 and P1 scores, level of distrust, and need for power, do play a significant role when determining the causes of civil war lethality.

Show moreThe purpose of this mixed-method phenomenological study is to understand the beliefs and attitudes that mid-career secondary school teachers have regarding the teacher evaluation process and its effect on their professional practice. 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.

(")At Face Value: Investigating Perception through Portraiture(") is a body of work that examines how people process their perception in imagery. The Deadpan Aesthetic, photographic truth and American identity are discussed, as well as the amount of influence a photographer has in his work. Since perception is defined as an understanding of setting via the senses, I hope to challenge viewers by employing strategies to destabilize the viewer's reception of my photographs.
