“News with an Accent”: Hispanic Television and the Re-negotiation of US Latino Speech     

Christopher A. Chávez 《传播与批判/文化研究》2013,10(3):252-270

Using Bourdieu's concept of “linguistic capital” as an analytical concept, I examine the value of language as both a means of comprehension and a product that has currency in the television marketplace. Focusing on Fusion, an upstart cable network designed to engage Latinos civically and in English, I examine the ways in which television networks employ language as a device through which to create audiences. I argue that Fusion and other networks are attempting to re-constitute the Latino audience in ways that more closely align with the dominant culture, leading to forms of erasure that challenge the legitimacy of Spanish altogether. I further argue that in the process of pursuing the acculturated Latino, the network pivots away from those most isolated from civic discourses.  相似文献

Strategically aligning a mandala of competencies to advance a transformative vision     

Nunzia B. Giuse  Sheila V. Kusnoor  Taneya Y. Koonce  Christopher R. Ryland  Rachel R. Walden  Helen M. Naylor  Annette M. Williams  Rebecca N. Jerome 《Journal of the Medical Library Association》2013,101(4):261-267

Objective:

This paper offers insight into the processes that have shaped the Eskind Biomedical Library''s (EBL''s) strategic direction and its alignment to the institution''s transformative vision.

Setting:

The academic biomedical library has a notable track record for developing and pioneering roles for information professionals focused on a sophisticated level of information provision that draws from and fuels practice evolutions.

Strategy:

The medical center''s overall transformative vision informs the creation of a fully aligned library strategic plan designed to effectively contribute to the execution of key organizational goals. Annual goals reflect organizational priorities and contain quantifiable and measurable deliverables. Two strategic themes, facilitating genetic literacy and preserving community history, are described in detail to illustrate the concept of goal setting.

Conclusion:

The strategic planning model reflects EBL''s adaptation to the ever-changing needs of its organization. The paper provides a characterization of a workable model that can be replicated by other institutions.  相似文献   

Simplified prototyping of perfusable polystyrene microfluidics     

Reginald Tran  Byungwook Ahn  David R. Myers  Yongzhi Qiu  Yumiko Sakurai  Robert Moot  Emma Mihevc  H. Trent Spencer  Christopher Doering  Wilbur A. Lam 《Biomicrofluidics》2014,8(4)

Cell culture in microfluidic systems has primarily been conducted in devices comprised of polydimethylsiloxane (PDMS) or other elastomers. As polystyrene (PS) is the most characterized and commonly used substrate material for cell culture, microfluidic cell culture would ideally be conducted in PS-based microsystems that also enable tight control of perfusion and hydrodynamic conditions, which are especially important for culture of vascular cell types. Here, we report a simple method to prototype perfusable PS microfluidics for endothelial cell culture under flow that can be fabricated using standard lithography and wet laboratory equipment to enable stable perfusion at shear stresses up to 300 dyn/cm² and pumping pressures up to 26 kPa for at least 100 h. This technique can also be extended to fabricate perfusable hybrid PS-PDMS microfluidics of which one application is for increased efficiency of viral transduction in non-adherent suspension cells by leveraging the high surface area to volume ratio of microfluidics and adhesion molecules that are optimized for PS substrates. These biologically compatible microfluidic devices can be made more accessible to biological-based laboratories through the outsourcing of lithography to various available microfluidic foundries.  相似文献

Interpretive validity theory: mapping a methodology for validating educational assessments     

Christopher DeLuca 《Educational research; a review for teachers and all concerned with progress in education》2013,55(3):303-320

Background:?Validity theory has evolved significantly over the past 30 years in response to the increased use of assessments across scientific, social and educational settings. The overarching trajectory of this evolution reflects a shift from a purely quantitative, positivistic approach to a conception of validity reliant on the interpretation of multiple evidence sources integrated into validity arguments. Moreover, within contemporary validity, interpretation has been emphasised as a central process; however, despite this emphasis, there have been few explicit articulations of specific interpretive methodologies applicable to the practice of validation.

Purpose:?To link contemporary theoretical foundations in validity to practical methods and structures to help guide the collection and analysis of interpretive validity evidence. By building upon existing validity theory, this paper aims to provide greater clarity on the practice of validation and contribute toward the larger developing framework for the validation of educational assessments.

Source of evidence:?An interdisciplinary, integrative review of over 60 research articles and sources related to the theory and practice of educational validation and interpretive inquiry approaches. Sources include literature from the fields of educational assessment and more broadly social scientific research.

Main argument:?As assessments in education increasingly aim to measure complex constructs that are value-laden and socially dependant, validity theory must keep pace and evolve in ways that address the inherent complexities associated with contemporary educational assessment. Through this paper, I assert that a greater understanding of interpretive methodologies represents one of the most promising areas for development of validation theory and practice. Specifically, I argue that dialectic, hermeneutic and transgressive forms of inquiry can be integrated within current argument-based structures for the collection, analysis and representation of validity evidence in several useful ways.

Conclusions:?Interpretive inquiry processes, namely dialectic, hermeneutic and transgressive forms of interpretation, serve to expand validation practice to include diverse evidences for the generation of multiple-perspective validity arguments. The paper concludes with specific implications for future research and practice within the field of interpretive validity theory.  相似文献   

Raising the bar: Encouraging high level thinking in online discussion forums     

Mary M. Christopher  Julie A. Thomas  Mary K. Tallent‐Runnels 《Roeper Review》2013,35(3):166-171

More universities are offering online instruction for students though we know little about effective online learning. Some have found online instruction increases student participation while others have reported that students prefer the traditional face‐to‐face format This study of gifted education graduate students follows the expectation that online students ought to have time to be more thoughtful with online course interactions as compared to the time‐constrained interactions in a face‐to‐face course. Researchers evaluated students’ thinking levels (as per Bloom's Taxonomy) in the online discussion forums required by a graduate course in gifted education. Results indicate there was no relationship between the level of the prompt and the level of the responses. Higher level prompts did not necessarily generate higher level responses. The research‐developed Rubric for Evaluation of Online Discussions can be used both as an instructional guide and as an evaluation rubric to assess the level of online discussions.  相似文献   

Planning for leadership succession: creating a talent pool in primary schools     

Mark Brundrett  Christopher Rhodes  Chrysanthi Gkolia 《Education 3-13》2013,41(3):259-268

This article reports on a study that was funded by the National College for School Leadership in order to explore practices, drivers and barriers to leadership talent identification, leadership development, leadership succession planning and leadership retention within a group of contextually different schools. The article offers two narratives from primary school headteachers, operating in different circumstances, in order to show the ways in which schools are attempting to ‘grow their own’ leaders through systematic policies for leadership development. Key features of successful schools which consider themselves to be good at leadership development, which may be relevant to other primary schools, are outlined.  相似文献   

Character education in three schools: Catholic,Quaker and public     

Christopher Meidl  Tynisha Meidl 《Education 3-13》2013,41(2):178-187

Character education has always played a role in the purpose of schools. Most US states have a statement about character education as a part of the mission of the schools. This research studied how character education was perceived by participants in regards to school mission statements/philosophies, school atmosphere and curriculum in a Catholic school, a Quaker school and a public school. Using interviews and observations, the public school and two private schools approaches to character education were explored. Character education explicitly connected and applied from the mission statement manifested more fully in the school culture.  相似文献   

Privatising form or function? Equity,outcomes and influence in American charter schools     

Christopher Lubienski 《牛津教育评论》2013,39(4):498-513

The American experiment with charter schools advanced on dual impulses of increasing opportunities for disadvantaged students and unleashing market competition. While critics see these independently managed schools as a form of privatisation, proponents contend that they are public schools because of funding and accountability arrangements and potential benefits, and believe that the economic logic around these schools will produce equitable educational opportunities. This analysis considers how charters are or are not instances of privatisation in education, showing that the marketised environment they are intended to nurture serves as a route for profit-seeking strategies. In reviewing the research on charter school organisational behaviour and outcomes in marketised environments, I find evidence of de facto privatisation in function if not in form. As charter schools often act like profit-seeking entities, but fail to achieve expected academic and equity outcomes, the concluding discussion considers how these schools are placed between conflicting goals, and serve as entry points for private organisations seeking to penetrate the publicly funded education sector. I conclude that perhaps their most important role is in serving as a vehicle for privatising public policy—diminishing the public while enhancing the position and influence of private interests and organisations in education policymaking.  相似文献
