Collaborative evaluation of a high school prevention curriculum: How methods of collaborative evaluation enhanced a randomized control trial to inform program improvement

Blending high-quality and rigorous research with pure evaluation practice can often be best accomplished through thoughtful collaboration. The evaluation of a high school drug prevention program (All Stars Senior) is an example of how perceived competing purposes and methodologies can coexist to investigate formative and summative outcome variables that can be used for program improvement. Throughout this project there were many examples of client learning from evaluator and evaluator learning from client. This article presents convincing evidence that collaborative evaluation can improve the design, implementation, and findings of the randomized control trial. Throughout this paper, we discuss many examples of good science, good evaluation, and other practical benefits of practicing collaborative evaluation. Ultimately, the authors created the term pre-formative evaluation to describe the period prior to data collection and before program implementation, when collaborative evaluation can inform program improvement.     

Performance models for unreliable flexible manufacturing systems

This paper deals with the analysis and application of queueing models for single and multi stage flexible manufacturing systems that are subject to resource failure. Exact results are derived for the single stage queueing system. Two approximations are presneted for the multi stage queueing system as a closed network. We validate the approximations by comparing their performance estimates against the exact global balance solution.     

Language ideologies and the consequences of standardization

This paper explores the effects of the standard language ideology on attitudes to language of nonlinguists and of language specialists, and considers how far linguists themselves have been affected by – and have contributed to – this ideology. The primary definition of standardization is taken to be the imposition of uniformity upon a class of objects . Attitudes to language within standard language cultures are then reviewed and contrasted with unstandardized situations, in which the boundaries of languages are indeterminate. It is therefore suggested that determinate languages, such as English, may be defined more by ideologies than by their internal structures. Some effects of standardization on the work of linguists are then reviewed. This is followed by a discussion of the importance of the process of legitimization in contributing to the standard language culture, and of the contribution of language specialists themselves to this process. Finally, certain matters arising are reviewed.     

Working Together to Improve Accessibility: Consortial E-Resource Accessibility and Advocacy

Abstract

In 2015, the Big Ten Academic Alliance (BTAA) Libraries formed the BTAA Library E-Resource Accessibility Group. This group, which consists of members from each Big Ten library and the BTAA Library Initiatives staff, was charged with creating boilerplate accessibility license language for vendor contracts, as well as collectively funding high level accessibility testing of e-resources and posting these publicly for all libraries and users. Since the creation of the group, about 50 databases have been tested and accessibility license language has been created that can be used and adapted by anyone. In 2019, the group welcomed another consortia, the Association of Southeastern Research Libraries (ASERL), to be partners in this work, renaming themselves the Library Accessibility Alliance. This paper examines the mission, accomplishments, and new partnership in more depth while also discussing the need for focused efforts to help ensure accessible e-resources.

Benedict Cumberbatch:天才最性感

泰戈尔在某部小说中说,女性手中的花环,要么挂在禽兽的恶汉脖子上,要么献给强同虚构人手般空想。因为女性在心底深处,渴望被肉欲的车轮碾碎,又或者在思想的烈火中融化--这种言辞似乎过于极端,好像女人都像受虐狂--不过,女人确实热爱幻想田人的强大,或肉体,或精神.
