Traveling South: Naples as a Site of Crossing and Migration in the Mediterranean

What sorts of images and narratives of cosmopolitanism are circulating in our cultural discourse? Stories and ideas based on experiences of migration, travel, and exile are considered in relation to the Italian city of Naples, to propose an example of “South-centric” cosmopolitanism. Two different journeys in the Mediterranean, as narrated by Moroccan writer Tahar Ben Jelloun and by Neapolitan film director Vincenzo Marra, engage with the experience of travel through stories that in opposite directions—the first from North Africa to Naples, and the second from Naples to North Africa—cross territories and lines of logic of Northern and Southern boundaries and deal with notions of belonging and homecoming.     

The Impact of Corporate Media News on Market Valuation

This article explores the influence of Web-based corporate reporting on the investors' valuation of companies in the information and communications technology industry. This study compiled 8,111 news items issued in the “Press Releases” tab of the firms' Web sites between January 2003 and April 2005, and analyzed what type of news items affects stock returns. The results show a positive price reaction to news regarding new customers, completion of acquisitions, strategic long-term decisions, and non-technological alliances. In contrast, the results show a negative price reaction to news regarding the launch of new or upgraded products.     

Teachers’ Commitment to the Field and Teacher–Child Interactions in Center-Based Child Care for Toddlers and Three-Year-Olds

Defining teacher characteristics that are associated with effective teaching continues to be a challenging task for the field of early care and education. Much of the research examining classroom quality has focused solely on teacher characteristics such as education and experience; However, teachers’ commitment to the field of early care and education defined as including job satisfaction, perception of the job as a long-term career, education level, years of experience, and membership in a professional organization may be an important characteristic to consider in teachers’ interactions with children in the classroom, especially teachers of very young children. Using the NICHD Study of Early Child Care data at 15, 24, and 36 months, the present paper examines characteristics of early childhood teachers’ commitment to the field and the assessed quality of teacher–child interactions in the classroom. Results indicate that overall, these characteristics significantly predict the quality of teachers’ emotional and cognitive support provided to children as measured by the Observational Record of the Caregiving Environment (ORCE). Characteristics of commitment to the field were stronger predictors of the cognitive support than the emotional support teachers’ provide in classrooms. The current work provides important information to consider in discussions of how characteristics of early childhood teachers influence their interactions with children in classrooms.     

Implementation of a Course Focused on Language and Literacy Within Teacher–Child Interactions: Instructor and Student Perspectives Across Three Institutions of Higher Education

Research suggests that teachers' interactions with preschool-age children have a significant influence on what children learn and the skills they develop. Additional research is needed to systematically determine the types of professional development that can help teachers learn effective teaching practices. This study is part of a larger effort to document the impact of a professional development model in which teachers learn how to implement effective teaching practices operationalized using the CLASS observation measure. A course developed by the National Center for Research on Early Childhood Education (NCRECE) was implemented in three higher education teacher preparation programs. This article describes the process of implementing the course and documents instructor and student perspectives on course delivery, content, and their learning. Results suggest that professional development in the form of a standardized course may be an effective means for presenting content related to language and literacy instruction within the context of information about effective teaching practices. Data from the study also indicate challenges associated with delivering a standardized course within multiple institutions of higher education.     

Assessing Beliefs of Preservice Early Childhood Education Teachers Using Q-Sort Methodology

The purpose of this study was to assess the beliefs of students and faculty in a 4-year birth–kindergarten teacher preparation program using the Teacher Belief Q-Sort (TBQ). Data were collected over one academic year from a total of 63 students, 35 students at the beginning of their coursework and 28 students at the end of their program, completing their student teaching experience. The faculty (n = 8) in the program completed the TBQ to provide a criterion sort as well as to assess the consistency in philosophy across faculty members who teach preservice teachers. Compilations of rankings are presented to describe beliefs related to children, discipline, and teaching practices held by students who are at different points in their education program. Criterion comparison results indicate that student teachers at the end of their education program report beliefs more similar to faculty beliefs than students at the beginning of their education program. However, findings suggest that the student teaching experience does not appear to significantly alter beliefs about children, discipline and teaching practices. These results are discussed in terms of child-directed versus teacher-directed styles of preservice teachers and implications of assessing beliefs for teacher preparation programs.

An examination of the relationship between verbal aggressiveness,conflict management strategies,and conflict interaction goals

The purpose of this investigation was to explore the relationship between respondents' trait verbal aggressiveness, conflict management strategies and conflict interaction goals. Data were collected from 105 undergraduate students at a small private affluent southeastern university. Participants were asked to recall a dispute that they had had with a close friend. They completed the OCCI, verbal aggressiveness, and conflict goals measures. Results indicated that verbal aggressiveness was associated in predictable ways with participants' conflict strategies. There also was a substantial and significant negative relationship between verbal aggressiveness and concerns about relational goals during conflicts. These results establish a foundation for future lines of research regarding conflict goals and extend previous investigations regarding verbal aggressiveness.     

Prospects for electronic publication in communication: A survey of potential users

This paper discusses the arguments for and against electronic publication and explores the potential acceptance for an electronic journal in the communication discipline. Using electronic mail, 85 users of a computer communication system were surveyed to determine the factors that would influence their decision to submit research reports to an electronic journal. The survey indicates that a majority of respondents would use an electronic journal to publish research reports and that most viewed publishing as a way to communicate about their work rather than a means for advancing in the field. The survey provides evidence that willingness to electronically publish decreased with higher occupational positions (from Masters student to Associate Professor) with this trend reversing itself at the level of Full Professor.     

Adenovirus-mediated wild-type p53 gene transfer in combination with bronchial arterial infusion for treatment of advanced non-small-cell lung cancer, one year follow-up

Objective: In the present study, we have examined the safety and efficacy of recombinant adenovirus encoding human p53 tumor suppressor gene (rAd-p53) injection in patients with advanced non-small-cell lung cancer (NSCLC) in the combination with the therapy of bronchial arterial infusion (BAI). Methods: A total of 58 patients with advanced NSCLC were enrolled in a non-randomized, two-armed clinical trial. Of which, 19 received a combination treatment of BAI and rAd-p53 (the combo group), while the remaining 39 were treated with only BAI (the control group). Patients were followed up for 12 months, with safety and local response evaluated by the National Cancer Institute's Common Toxicity Criteria and response evaluation criteria in solid tumor (RECIST), respectively. Time to progression (TTP) and survival rates were also analyzed by Kaplan-Meier method. Results: In the combo group,19 patients received a total of 49 injections of rAd-p53 and 46 times of BAI, respectively, while 39 patients in the control group received a total of 113 times of BAI. The combination treatment was found to have less adverse events such as anorexia, nausea and emesis, pain, and leucopenia (P<0.05) but more arthralgia. fever, influenza-like symptom, and myalgia (P<0.05), compared with the control group. The overall response rates (complete response (CR)+partial response (PR)) were 47.3% and 38.4% for the combo group and the control group, respectively (P>0.05). Patients in the combo group had a longer TTP than those in the control group (a median 7.75 vs 5.5 months, P=0.018). However, the combination treatment did not lead to better survival, with survival rates at 3, 6, and 12 months in the combo group being 94.74%, 89.47%, and 52.63%, respectively, com-pared with 92.31%, 69.23%, and 38.83% in the control group (P=0.224). Conclusion: Our results show that the combination of rAd-p53 and BAI was well tolerated in patients with NSCLC and may have improved the quality of life and delayed the disease progression. A further study to better determine the efficacy of this combination therapy is warranted.
