Sythesis and Characterization of [(C5R5) M (CO)2 (L2)]+: R=H, Me and Ph; M=Cr and Mo; L2=dmpe and dppe

For two decades much research has been concentrated on open-shell transition metal complexes as chemical intermediates. To date, most efforts have concentrated on electron deficient, 17-electron (17e) compounds; however past research has shown that electronically supersaturated, 19-electron (19e) complexes can also participate as intermediates in many reactions. Yet, excluding (C5 H5)Fe(C6 H6) type complexes, very few of these compounds have been prepared.2,3 To better understand the nature of 19e, the preparation of another series of compounds is desirable. The addition of the bidentate Lewis bases 1,2- bis(dimethylphosphino)ethane (dmpe) or 1,2-bis(diphenylphosphino)ethane (dppe) to a mixture of [(C5 R5)M(CO)3] x (X= 2 for R= H, Me, Ph; M = Cr, Mo and X=1 for M=Cr, R=Ph) and [Cp2 Fe]PF6, produces [(C5 R5)M(CO)2dmpe]+ or [(C5 R5)M(CO)2dppe]+ except for M=Cr, R=Ph, respectively (eq 4). (C5 R5) M(CO)3 + L2 + Cp2 Fe+ → (C5 R5) M(CO)2(L2) +CO + Cp2 Fe

Student Achievement and Teacher Perception in Small Schools and Large Schools

The study analyzed student achievement in various school sizes and teachers\u27 perceptions of relationships and interactions with colleagues, students, and parents depending on the size of the school in which teachers work. The purpose was to assist school leaders when they are faced with decisions about school size. Simple linear regression was used to analyze the relationship of achievement and school size of fourth-grade students. The variables mathematics achievement and size and language arts achievement and size were positively correlated. These findings suggest that as the size of a school increases, achievement increases. After holding the variables socioeconomic status and race constant, the negative correlation was found between mathematics achievement and size, suggesting that as the size of a school decreases, achievement increases. The means of the levels of teachers\u27 perceptions in large schools and small schools were compared using an independent t test. Two significant differences were found between teachers\u27 perceptions of relationships and interactions with colleagues, students, and parents

Internationalization initiatives in U.S. institutions of higher education : the impact observed by a school of music

Dissertation Advisor: Dr. David Stader.Field of study: Educational leadership and policy analysis."May 2018."This qualitative study was designed to evaluate the impact internationalization initiatives in U.S. institutions of higher education have had on a school of music. The critical approach of intercultural communication served as the conceptual framework to guide understanding of internationalization initiatives or efforts within higher education institutions toward preparing students, in particular music graduates, for the global society (Issa, 2015). Data collected from questionnaires and interviews with various stakeholders, organizational documents and the institution's website provided a more thorough understanding of the approach to, and challenges and benefits of internationalization initiatives in a school of music. This data was coded for consistencies and emerging themes in terms of approaches to, challenges, and benefits. The results of this study could create social change for society and communities in better understanding the impact of internationalization initiatives implemented within higher education music departments toward enhancing the artistic and intellectual abilities and contributions of individuals, institutions, and the field of music as a whole. Findings from this study will also inform practices of administrators of music departments within higher education toward attracting and preparing international students as well as preparing current domestic students for a globalized society.Includes bibliographical references (pages 108-112)

Programming the Properties of Branched Polymers Through Precision Architectures

The glass transition of branched polymers is determined by multiple structural parameters that dictate their inter- and intramolecular interactions, and ultimately, their molecular packing in the amorphous phase. Here we examined the impact of side chain length, backbone length, molecular weight composition, and topology on the glass transition behavior of bottlebrush polymers. Through examining precision bottlebrush polymer libraries (PBP, ĐSC = 1.0), we find the infinite molecular weight Tg is reached at a specific brush length after which the effect of the side-chain length dominates. Being a factor more dominant than the backbone, side-chain length affects the Tg of bottlebrush polymers across all sizes and topology variations. To demonstrate the versatility of side chain engineering strategies, a broad range of Tg and glass transition behavior was targeted through judicious choice of side chain length, blend ratios, and brush topology. PBPs yield precise Tg with some values only accessible through making PBP blends at the cost of Tg broadening. Ultimately, multiblock PBPs combine the best features of both approaches; the ability to target arbitrary Tg while maintaining sharp glass transition

Non-traditional adult education : a survey study of the Career Opportunity Program in Springfield, Massachusetts, as a prototype.

This study focuses on the education of adult students as being more complex than traditional students. Because jobs are more complex, and the growing emphasis on credentials, these factors create a demand for better access to a greater range of educational programs. These demands can be an opportunity for creative institutions to design individualized curricula, new roles for faculty, and new approaches to learning. The (COP) Project was designed to do some of the above in the past. A survey study focusing on participants in the (COP) Project in Springfield, Massachusetts, was conducted. Three questions were addressed: (1) Was (COP) able to attract persons who would not normally have pursued educational careers? (2) Did (COP) provide career ladders for the participants. (3) Did (COP) improve education and career advancement for the participants. A sample of 75 participants were selected from the Springfield (COP) Project based on their availability. A questionnaire was mailed to the participants and a return rate of 50% was achieved. Some highlights of the responses collected were: (1) The participants viewed the (COP) Project participants, instructors, and administrators as being very supportive, cooperative, flexible, and available when help was needed. (2) There was strong evidence of support among the participants. (3) The participants were appreciative of the opportunity offered by (COP). (4) The participants indicated that without COP, their goals would not have been achieved. Generally, there were only positive comments about the (COP) Project. The only negative comments were that the program ended when there were many more people in need. The data indicated a need for more men in the secondary school levels for, role models, and that over 75% of those entering education through the COP remained and pursued advanced degrees. The participants were more secure and comfortable, learning with other adults from similar backgrounds. It is suggested that the work environment is considered a potential learning environment, and that learning is not limited to academic institutions but a lifelong process

The rhetoric of ‘community’ : ABC local radio\u27s coverage of the 2009 Victorian bushfires

This article joins recent debates in media and communication studies concerning audience participation in news journalism. Specifically, we investigate the impact of an increasing reliance on audience-generated content on newsroom practice in traditional media organisations. We do this by recounting and analysing the experiences of journalists involved in ABC Radio\u27s coverage of the dramatic Victorian bushfires of early 2009, which relied heavily in listener contributions and was closely integrated with the ABC\u27s online coverage. Interviews with two staff at ABC Gippsland, and the ABC\u27s Manager of Emergency Broadcasting provide the basis for a case study of the kinds of tensions that media workers routinely confront within an organisation like the ABC. The interviews suggest that in negotiating the possibility of increased audience participation, journalists and their managers are thinking about much more that the rhetorics of democracy and the validity of news values: their focus is also on a complex structure, the need for skill (re)development and the precise mechanics of creating and maintaining productive relationships with local communities. The significance of the research lies in its attempt to bring together a number of related factors: the increasingly active role of audiences in generating and supplying news content; the impact of digital communications technologies on news production practices; and the ABC\u27s ongoing development of its now contested role as an \u27emergency broadcaster\u27
