Young people today are increasingly disengaged from their education. Studies indicate that of all school subjects, American students struggle to engage in STEM subjects more than others. For decades, we have known that student engagement/disengagement impacts teachers. Researchers have also claimed that engagement/disengagement can be described as a construct made up of affective, behavioral, and cognitive dimensions (ABC). However, we do not understand how teachers experience student disengagement in these three areas. At a crucial time in education, investigation into the experiences of teachers with disengaged students is needed to uncover insights which may help us understand how teachers interpret student disengagement as well as how they cope with or mitigate it. In this study, we report findings from interviews with STEM teachers where they used an operationalized form of the ABC disengagement construct to interpret previous experiences with disengaged students. We discuss their recommendations for coping and mitigation. Chief among our findings is that when our subjects were introduced to the construct, they were then able to identify strategies to help address student's disengagement patterns. An operationalized form of the ABC disengagement construct may be useful for practitioners to diagnose and remedy student disengagement.

In this thesis I combine the social network analysis approach with the traditional experimental approach to study the phenomena of jury decision-making. I examine whether with each trial a social network is formed. The jurors, the two teams of lawyers, as well as the accused and the judge, all form a social network with cliques and leaders. This division of individuals into specific cliques, along with the lawyers' performance in court, is hypothesized to have a significant impact on the jury's verdict. <br /><br /> Thus, by specifically studying the lawyers' engagement and disengagement on the jurors during a trial and the impact this has on the verdict, as well as understanding the structure of the social network that the individual jurors create, I hope to shed light on some of the influences that are key in delivering the verdict. In addition, this pioneering study may lead to significant policy changes in the future.

Cognitive views of the psychopathology of anxiety propose that attentional biases toward threatening information play a substantial role in the disorders’ etiology and maintenance. For healthy subjects, converging evidence show that threatening stimuli attract attention and lead to enhanced activation in visual processing areas. It is assumed that this preferential processing of threat occurs at a preattentive level and is followed by fast attentional engagement. High-anxious individuals show augmented tendencies to selectively attend toward fear-relevant cues (Mathews, 1990) and exhibit elevated neural processing of threatening cues compared to non-anxious individuals (Dilger et al., 2003). Regarding attentional biases in high-anxious subjects, it remains unanswered up to now whether initial engagement of attention toward threat or difficulties to disengage from threat is an underlying mechanism. Furthermore, little is known whether the preferential (attentive) processing of threatening cues does influence perceptional outcomes of anxious subjects. In order to directly study separate components of attentional bias the first study of this dissertation was a combined reaction time and eye-tracking experiment. Twenty one spider phobic patients and 21 control participants were instructed to search for a neutral target while ignoring task-irrelevant abrupt-onset distractor circles which contained either a small picture of a spider (phobic), a flower (non-phobic, but similar to spiders in shape), a mushroom (non-phobic, and not similar to spiders in shape), or small circles with no picture. As expected, patients’ reaction times to targets were longer on trials with spider distractors. However, analyses of eye movements revealed that this was not due to attentional capture by spider distractors; patients more often fixated on all distractors with pictures. Instead, reaction times were delayed by longer fixation durations on spider distractors. This result does not support automatic capture of attention by phobic cues but suggests that phobic patients fail to disengage attention from spiders. To assess whether preferential processing of phobic cues differentially affects visual perception in phobic patients compared to healthy controls, the second study of this dissertation used a binocular rivalry paradigm, where two incompatible pictures were presented to each eye. These pictures cannot be merged to a meaningful percept and temporarily, one picture predominates in conscious perception whereas the other is suppressed. 23 spider phobic patients and 20 non-anxious control participants were shown standardized pictures of spiders or flowers, each paired with a neutral pattern under conditions of binocular rivalry. Their task was to continuously indicate the predominant percept by key presses. Analyses show that spider phobic patients perceived the spider picture more often and longer as dominant compared to non-anxious control participants. Thus, predominance of phobic cues in binocular rivalry provides evidence that preferential processing of fear-relevant cues in the visual system actually leads to superior perception. In combination both studies support the notion that phobic patients process phobic cues preferentially within the visual system resulting in enhanced attention and perception. At early stages of visual processing, this is mainly reflected by delayed attentional disengagement and across time, preferential processing leads to improved perception of threat cues. / Kognitive Theorien nehmen an, dass Aufmerksamkeitsverzerrungen bezüglich bedrohlicher Reize eine substantielle Rolle bei der Entstehung und Aufrechterhaltung von Angst spielen. Für gesunde Personen konnte gezeigt werden, dass bedrohliche Reize die Aufmerksamkeit auf sich ziehen und verstärkt im visuellen System verarbeitet werden. Es wird angenommen, dass diese bevorzugten Verarbeitungsprozesse automatisch und präattentiv sind und von einer schnellen Aufmerksamkeitsausrichtung gefolgt werden. Hochängstliche Personen zeigen eine verstärkte Tendenz, ihre Aufmerksamkeit selektiv auf Gefahrenreize auszurichten (Mathews, 1990) und verarbeiten diese Reize auch auf neuronaler Ebene intensiver als nichtängstliche Personen (Dilger, et al., 2003). Bisher ungeklärt ist, ob bedrohliche Reize tatsächlich die Aufmerksamkeit initial auf sich ziehen oder ob die beschriebenen Aufmerksamkeitsverzerrungen besserdurch Schwierigkeiten, Aufmerksamkeit von Gefahrenreizen abzuwenden, erklärt werden können. Darüberhinaus wurde bisher kaum untersucht, ob sich eine bevorzugte Verarbeitung von angstrelevanten Reizen auch auf die Wahrnehmung ängstlicher Personen auswirken kann. Um verschiedene Aufmerksamkeitskomponenten direkt zu untersuchen, wurden in der ersten Studie dieser Dissertation sowohl manuelle Reaktionszeiten als auch Augenbewegungen erfasst. 21 Patienten mit Spinnenphobie und 21 nichtängstliche Kontrollpersonen sollten während der Suche nach einem neutralen Zielreiz aufgabenirrelevante kreisförmige Reize explizit ignorieren, die kleine Bilder von Spinnen (phobisch), Blumen (nicht phobisch, aber mit spinnenähnlicher Form), Pilzen (nicht phobisch und keine spinnenähnliche Form) oder kein Bild enthalten konnten. Wie erwartet zeigte sich, dass die Reaktionszeiten der Patienten in den Durchgängen langsamer waren, in denen aufgabenirrelevante Spinnen auftauchten. Allerdings zeigte die Analyse der Augenbewegungen, dass die Spinnen initial nicht häufiger fixiert wurden, sondern die Patienten häufiger auf alle Distraktoren mit Bild schauten. Allerdings verweilte der Blick der Patienten länger auf den Spinnenbildern, was die verlangsamten Reaktionen auf den Zielreiz erklären kann. Diese Befunde unterstützen nicht die Annahme einer automatischen Entdeckung phobischer Reize, sondern weisen vielmehr auf Schwierigkeiten phobischer Patienten hin, die Aufmerksamkeit von Spinnen zu lösen. In der zweiten Studie dieser Dissertation wurde ein binokulares Rivalitätsparadigma eingesetzt, um zu untersuchen, ob eine bevorzugte Verarbeitung phobischer Reize die visuelle Wahrnehmung bei Patienten mit Spinnenphobie beeinflussen kann. Bei diesem Paradigma wird jedem Auge ein unterschiedliches Bild dargeboten, was zu einem Wahrnehmungswechsel führt, bei dem jeweils ein Bild die bewusste Wahrnehmung dominiert während das andere unterdrückt wird. 23 Patienten mit Spinnenphobie und 20 nichtängstlichen Kontrollpersonen wurden standardisierte Bilder von Spinnen und Blumen, jeweils gepaart mit einem neutralen Muster, stereoskopisch dargeboten. Die Aufgabe bestand darin, durchgehend die dominante Wahrnehmung durch Tastendruck zu kodieren. Patienten mit Spinnenphobie berichteten häufiger und länger, Spinnenbilder dominant wahrzunehmen. Diese Wahrnehmungsdominanz von phobischen Reizen bei binokularer Rivalität weist darauf hin, dass eine bevorzugte Verarbeitung bedrohlicher Reize im visuellen System dazu führen kann, dass diese Reize auch verstärkt wahrgenommen werden. Zusammenfassend unterstützen die Befunde beider Studien die Annahme, dass Patienten mit Spinnenphobie phobierelevante Reize innerhalb des visuellen Systems bevorzugt verarbeiten, was sich in verzögerter Aufmerksamkeitsabwendung zeigt und des Weiteren zu einer verstärkten Wahrnehmung der bedrohlichen Reizen führt.

This observational study surveyed the engagement of fifth-grade gifted students who spend the majority of their academic day in a general education classroom. This study looked at students in a K-6 public school district in Southern California. This study was a qualitative study with some quantitative data to confirm observational findings. The methods included observations, observational notes, audio and video recordings. After the observations the recordings were reviewed to assure the observational notes accurately portrayed the actions of the target students. The measures included student surveys, observational data via the Behavioral Observation of Students in Schools instrument, and teacher interviews. The short response portion of the student surveys and the teacher interviews were coded and analyzed for common themes. The research questions that dictated the direction of this study included: Is student engagement altered by use of differentiated curriculum, if so is it increased or decreased with more appropriate assignments for gifted students? Do students put forth the same effort with more complex assignments as with easier assignments? Do fifth-grade gifted students show signs of a lack of student engagement? Further research may include expanding the study to include more students from various school districts to ascertain if the findings are consistent with other groups of students.

When organizational leaders create cultures that foster employee engagement, the leaders experience multiple benefits such as enhanced organizational performance, increased profitability, and improved retention rates. Although small business leaders must create and sustain atmospheres that nurture employee engagement to experience maximized success, 85% of organizational leaders struggle with executing strategies that increase engagement. The purpose of this qualitative, single case study was to explore strategies that small business leaders use to increase employee engagement. Servant leadership theory was the conceptual framework chosen for this study. The population included 3 small business leaders of a coffee shop located in Birmingham, AL. A review of company documents, as well as member checking of initial interview transcripts, helped to strengthen the credibility and trustworthiness of the interpretations. The final interpretations consisted of 2 main themes: creating a culture that enhances and sustains employee engagement and demonstrating leadership characteristics that increase employee engagement. Employee engagement increases when leaders use strategies that include effective employee development strategies, incentives and rewards, deliberate hiring practices, effective communication, leading by example, and leveraging employee innovation and ownership. These findings influence positive social change by uncovering strategies necessary to increase employee engagement, because employees who engage in the workplace display stronger forms of attachment to businesses, develop a significant bond within the community, and experience improved family interactions.

Romantic disengagement is a disturbingly prevalent yet understudied cause of marital distress and dissolution. Existing research on disengagement has been primarily descriptive and limited by reliance on retrospective reports from already disengaged spouses. Theoretically informed prospective research to elucidate the process through which some spouses become increasingly disengaged from their partners over time is necessary to facilitate clinical intervention efforts. Thus the purpose of this research was to propose a theoretically informed model of the process of romantic disengagement and then to perform preliminary tests of pieces of the model. The model was tested in a sample of 103 married couples assessed six times over their first seven years of marriage. Pieces of the model that were tested included (1) the implication that avoidant and disengaging behaviors toward one's partner, particularly during times of need or increased stress (such as marital conflict interactions), are indicators of a process of romantic disengagement, (2) that predispositional and contextual factors interact to predict a spouse's greater tendency to behave avoidantly during couple interactions, and (3) that spouses tendency to be more avoidant with his or her partner later in marriage will be greater to the extent that avoidance is reinforced early in marriage. First, I examined whether avoidant behavior during marital conflict contributes to a process of romantic disengagement as evidenced by declines in trust and intimacy and declines in marital satisfaction. Consistent with hypotheses, I found higher conflict avoidance was associated with declines in trust and intimacy and declines in marital satisfaction. Second, I tested two predispositional (i.e., spouses' attachment avoidance and avoidant coping style) and two contextual factors (spouses' role during support interactions, and the partner's negative affect) that were expected to interact to predict whether spouses behave avoidantly during specific couple interactions. I found mixed support for hypotheses depending on spouse and interaction type. Specifically, during conflict interactions, husbands and wives with higher attachment avoidance, and wives with more avoidant coping styles, behaved more avoidantly to the extent that their partners were higher in negative affect. During supportive transactions, husbands with more avoidant coping styles were more disengaged to the extent that their wives were higher in negative affect. Third, I tested my hypothesis that a spouse will be more avoidant with his or her partner later in marriage to the extent that avoidance is reinforced early in marriage. I found partial support for this hypothesis. Husbands' disengagement during conflict interactions interacted with improved mood post-interaction to predict husbands' disengagement across interactions at 7 years of marriage. In summary, this research presents an integrated theoretical model of romantic disengagement and provides preliminary support for aspects of the model.

Continuing education (CE) in nursing is a critical element in assuring quality health care for the public. Rapid changes in technology and increasing emphasis on utilizing current research findings in practice increases the importance of participation in CE. Many nurses, however, do not attend CE sessions. As provincial professional associations are looking at ways to ensure competency in practice, the issue of who participates in CE and who does not is becoming more relevant to employers and educators. p*A review of the literature found that while many studies looked at factors that increase participation in CE, few examined deterrents or barriers to CE participation in nursing. Few studies were found comparing CE participants with nonparticipants. <p>This comparative descriptive study examined the similarities and differences between participants and nonparticipants of CE. Questionnaires, including the 40-item Deterrents to Participation Scale as well as some demographic and recent CE participation information, were distributed to a sample of acute care nurses in three different-sized hospitals in Saskatchewan. To maximize response rates, Dillmans Total Design Method for surveys was used where possible. <p>Means of the interval data was compared between the participants and nonparticipants. Cross tabulations were used to explore relationships among non-interval data. <p>This study provided valuable insights into participation and nonparticipation in CE, and will thereby help employers and educators develop a deeper understanding of possible strategies that could increase participation in CE.
