Advancing Culturally Relevant Pedagogy in a Secondary Methods Course

Given changes in the U.S. school-age population, it is crucial that colleges of education prepare teacher candidates to work effectively with students from diverse backgrounds. Because diversity constitutes such a small portion of the curriculum in many teacher education programs, it is crucial that teacher educators find creative ways to incorporate diversity into the courses they teach. In this article a teacher educator at a predominantly White institution in the American Southeast describes how she introduces culturally relevant pedagogy and connects it to the content, activities, and assessments included in the remainder of a course.     

档案开放负面清单制度构建：逻辑与框架

文章对负面清单制度的历史沿革与发展现状进行了梳理;针对延期开放的范围和期限不够明晰的问题,论证了将负面清单管理思想应用于档案开放的理论与现实逻辑;在此基础上,依托政务公开负面清单制度的基本架构,从内容、过程、保障三个层面分别提出了由三个维度、四个步骤、三项机制共同构成的档案开放负面清单制度框架,推动档案开放工作在法治化、规范化轨道上良性运行。     

Whole blood pumping with a microthrottle pump

We have previously reported that microthrottle pumps (MTPs) display the capacity to pump solid phase suspensions such as polystyrene beads which prove challenging to most microfluidic pumps. In this paper we report employing a linear microthrottle pump (LMTP) to pump whole, undiluted, anticoagulated, human venous blood at 200 μl min(-1) with minimal erythrocyte lysis and no observed pump blockage. LMTPs are particularly well suited to particle suspension transport by virtue of their relatively unimpeded internal flow-path. Micropumping of whole blood represents a rigorous real-world test of cell suspension transport given blood's high cell content by volume and erythrocytes' relative fragility. A modification of the standard Drabkin method and its validation to spectrophotometrically quantify low levels of erythrocyte lysis by hemoglobin release is also reported. Erythrocyte lysis rates resulting from transport via LMTP are determined to be below one cell in 500 at a pumping rate of 102 μl min(-1).     

The relationships between step count and all-cause mortality and cardiovascular events: A dose–response meta-analysis

BackgroundA goal of 10,000 steps per day is widely advocated, but there is little evidence to support that goal. Our purpose was to examine the dose–response relationships between step count and all-cause mortality and cardiovascular disease risk.MethodsCochrane Central Register of Controlled Trials, EMBASE, OVID, PubMed, Scopus, and Web of Science databases were systematically searched for studies published before July 9, 2021, that evaluated the association between daily steps and at least 1 outcome.ResultsSixteen publications (12 related to all-cause mortality, 5 related to cardiovascular disease; and 1 article contained 2 outcomes: both all-cause death and cardiovascular events) were eligible for inclusion in the meta-analysis. There was evidence of a nonlinear dose–response relationship between step count and risk of all-cause mortality or cardiovascular disease (p = 0.002 and p = 0.014 for nonlinearity, respectively). When we restricted the analyses to accelerometer-based studies, the third quartile had a 40.36% lower risk of all-cause mortality and a 35.05% lower risk of cardiovascular event than the first quartile (all-cause mortality: Q1 = 4183 steps/day, Q3 = 8959 steps/day; cardiovascular event: Q1 = 3500 steps/day, Q3 = 9500 steps/day; respectively).ConclusionOur meta-analysis suggests inverse associations between higher step count and risk of premature death and cardiovascular events in middle-aged and older adults, with nonlinear dose–response patterns.     

Confirmative Evaluation of Training Outcomes

This article explores the use of an evaluation model of learning and development utilizing formative, summative, and confirmative steps, along with a framework for developing evaluation tools aligned with organizational change goals. A case study is presented in which formative, summative, and confirmative evaluations were used to assess materials and learners following implementation of a new performance management process, tools, and supporting training. A specific model for developing evaluation tools and techniques is introduced as a way to integrate the evaluation process with the specific content of a learning and development intervention, as well as link to higher‐order cultural change goals. Results of the case study suggest that evaluation tools can provide evidence of improvement and target areas for further work. Recommendations are provided for the researcher or practitioner interested in applying the same or similar models to evaluation.     

Using Computing Power to Replace Lawyers: Advances in Licensing and Access

Faculty, librarians, students, and administrators are all faced with questions concerning permitted uses of licensed content. Rather than wrangle with the complexities of copyright, many would prefer a simple automated solution. The Stanford Center for Legal Informatics created such a tool through a research project that evolved into SIPX, a commercial copyright service. The Copyright Clearance Center (CCC) created a product concept but faced challenges in converting it into an academic product.     

Lessons from professional identity development literature: A qualitative content analysis

The development of a professional identity as a counselor is the result of training, practice, and integration into a community of professional counselors and is defined as the synthesis of personal and professional behaviors, values, ethics, and worldview. The research on this topic has been plentiful, but this systemic and systematic review of the research literature provides a comprehensive overview of this important concept for counselor training and supervision.
