Who Ya Gonna Call? Networks of Rural School Administrators

When they need help or advice, who are rural school administrators going to call? Relationships among rural school administrators develop into networks that can affect the success of administrators and their schools. Understanding the structure and content of these networks provides insights into how resources, innovations, and communication flow both within and between rural district administrators. Based on network theory and analysis, this study examines the structure, content, and strategic implications of the administrative networks within and across six contiguous rural school districts in the Western United States. Network graphs are included, illustrating both individual district and the combined six-district rural administrator networks. While acquaintance ties and active work ties are evident both within and across districts, relationally embedded ties and greater cohesion of ties are more evident within districts than across districts. Analyses include consideration of administrative assignment, gender, and geographical location of the network structures. Strategic implications of the network structures and content are discussed

Preservice Teacher Preparation in International Contexts: A Case-Study Examination of the International Student Teacher Programs

This article examines the teacher preparation experiences of preservice teachers in six international contexts: China, Fiji, Kiribati, Mexico, Samoa, and Tonga. More specifically, it looks at the value-added components in an international teacher education program, with an emphasis on effective teaching and employability. Theoretically the study is based on Straus and Corbin’s (1998a) substantive grounded theory and Patton’s (1997) Theory of Action Framework. Verbal and non-verbal forms of feedback were identified as essential aspects of the international preservice training experience. Cultural diversity, teaching English as a second language, collaboration, and exposure to a different educational system were identified among several components as advantages to individuals who conduct their preservice teacher training in international settings.</jats:p

Leader Emergence and Effectiveness in Virtual Workgroups: Dispositional and Social Identity Perspectives

In today's global competitive environment, many organizations utilize virtual workgroups to overcome geographic and organizational boundaries. Research into their dynamics has received the attention of scholars within multiple disciplines, and the potential for an integrative approach to the study of virtual workgroups exists. This dissertation is a first step towards such an approach. The primary aim of this research is to examine antecedent and contextual factors that affect the emergence and effectiveness of leaders in virtual workgroups. To achieve this aim, an integrative model assembled from theory and empirical findings in leadership, management, social identity, and communications research is posited. Hypothesized relationships depicted in the model identify key dispositional and contextual variables linked to leader emergence, member behavior, and leader effectiveness within virtual workgroups. This study employed a nonexperimental research design, in which leader emergence and social identity manifest as naturally occurring phenomena. Data collection occurred via two web-based surveys administered at different points in time. Hypothesized relationships were tested utilizing correlational and hierarchical moderated multiple regression analyses. The findings of this dissertation suggest that traits, such as personality and cognitive ability, are not associated with leader emergence in virtual workgroups. In addition, the results indicate that the exhibition of relationship-oriented leader behaviors enhances group identity. In turn, identification is associated with increases in perceptions of leader effectiveness and decreases in counterproductive behavior exhibited by group members. This dissertation exposes an important limitation to the application of trait leadership theory. It also demonstrates the importance of relationship-oriented behavior and social identity in virtual contexts. Further, it advances an integrative theoretical model for the study of virtual workgroup phenomena. These contributions should assist and inform other researchers, as well as practitioners, interested in leadership and group member behavior in virtual workgroups

Observation of quantum oscillations between a Josephson phase qubit and a microscopic resonator using fast readout

We have detected coherent quantum oscillations between Josephson phase qubits and microscopic critical-current fluctuators by implementing a new state readout technique that is an order of magnitude faster than previous methods. The period of the oscillations is consistent with the spectroscopic splittings observed in the qubit's resonant frequency. The results point to a possible mechanism for decoherence and reduced measurement fidelity in superconducting qubits and demonstrate the means to measure two-qubit interactions in the time domain

Medically attended pediatric influenza during the resurgence of the Victoria lineage of influenza B virus

SummaryObjectivesDuring the 2002–2003 season, a new variant of influenza B co-circulated with influenza A viruses. This study examines the characteristics and outcomes of children with influenza A and B virus infection vs. other acute respiratory illnesses.MethodsA retrospective chart review was performed on children with laboratory-confirmed influenza infection, and influenza negative acute respiratory illnesses that prompted a hospital visit.ResultsChildren with influenza were more often previously healthy and presenting with upper respiratory symptoms, while influenza negative patients typically had underlying medical conditions, and lower respiratory tract disease. Children with influenza B were older, were more likely to be in school, and presented with myositis more frequently than those with influenza A. A third of children with influenza A, and 42% with influenza B required hospitalization. The highest hospitalization rates were in infants under one year. No healthy children, and only 15% of those with chronic medical problems, had received influenza vaccine. Vaccine efficacy was estimated to be 82.6%.ConclusionsMost children with influenza were previously healthy. Overall, a third of children with influenza required hospitalization. Influenza A and B were clinically indistinguishable, except for older age and higher incidence of myositis in patients with influenza B. Influenza vaccine coverage in both healthy and high-risk children was low

Assessment of the Perceived Role and Function of a Community Advisory Board in a NIH Center of Excellence: Lessons Learned

Background: The Community Advisory Board (CAB) was a vital component of the Center for Equal Health. The center addressed health disparities through community-based research and educational outreach initiatives. Objectives: To evaluate the perceived relationship of the CAB and Center, explore members’ perceptions of the CAB’s role, and elicit feedback on how to enhance the relationship between the Center and the CAB. Methods: Ten in-depth, semi-structured interviews were conducted. All interviews were transcribed verbatim and analyzed with a focus on predetermined codes. Results: Main themes focused on perception of CAB roles and need for utilization of board members; overall center challenges; and board member knowledge and communication within the center. Conclusions: Lessons learned mainly focused on clarification of CAB roles as necessary for more effective and efficient communication. Based on feedback, communication channels between the board and center were developed, orientation packets clarifying center roles were provided, and annual retreats were completed. Additional lessons learned for conducting community-academic partnerships are provided
