Portable X-ray fluorescence analysis of pesticides in the textile collection at the German Historical Museum,Berlin

The majority of the objects found in the textiles collection at the German Historical Museum in Berlin have been treated with different biocides at various points in the past. Prior to this study, the presence of organochlorinated pesticides in rooms and storage cabinets had already been proven in an analysis of air samples that employed gas chromatography and mass spectroscopy. To estimate the risks these toxins pose to both collections and museum staff, we conducted a field study with the help of a portable X-ray fluorescence spectrometer. In this study, we present an attempt at a reliable quantitative analysis. In addition to chlorine, other potentially hazardous elements such as lead, arsenic, and mercury were found in the majority of the objects. In some cases, however, it has to be taken into account that the detected elements might have originated from manufacturing processes rather than biocide treatments. Such knowledge is a crucial prerequisite to proper risk prediction.     

Outcomes assessment: an examination of the ETS major field test and the comprehensive business exam

This study is the first to examine student performance differences between the major field test in business (MFTB) and the comprehensive business exam (CBE). Results reveal students performed at a statistically significant 50.8 percentile ranking on the CBE compared to a 38.0 percentile ranking on the MFTB. Additionally, this study finds that students transferring business core courses with a grade point average (GPA) of 2.5 or lower perform at a statistically significant lower level on both the MFTB and the CBE than those transferring business core courses with GPAs higher than 2.5. These findings have important implications for assessment of learning purposes.     

Promoting Student–Teacher Interactions: Exploring a Peer Coaching Model for Teachers in a Preschool Setting

Peer coaching provides an attractive alternative to traditional professional development for promoting classroom quality in a sustainable, cost-effective manner by creating a collaborative teaching community. This exploratory study describes the development and evaluation of the Colleague Observation And CoacHing (COACH) program, a peer coaching program designed to increase teachers’ effectiveness in enhancing classroom quality in a preschool Head Start setting. The COACH program consists of a training workshop on coaching skills and student-teacher interactions, six peer coaching sessions, and three center meetings. Pre-post observations of emotional support, classroom organization, and instructional support using the Classroom Assessment Scoring System of twelve classrooms assigned to peer coaching were compared to twelve control classrooms at baseline and following the intervention. Findings provide preliminary support that the peer coaching program is perceived as acceptable and feasible by the participating preschool teachers and that it may strengthen student–teacher interactions. Further program refinement and evaluation with larger samples is needed to enhance student–teacher interactions and, ultimately, children’s adaptive development.     

Intended Consequences: Challenging White Teachers’ Habitus and Its Influence in Urban Schools Implementing an Arts-Based Educational Reform

Reform efforts like the urban, arts-based initiative Project ARTS are designed to provide intentional, equitable methods of improving students’ learning, yet few urban educators have been sufficiently trained to recognize differences in habitus between themselves and their students. For equitable reform to occur teachers must understand their own habitus and the habitus-forming experiences of their students. In this paper, we analyze qualitative project data using Bourdieu’s theoretical concepts of cultural capital, field, habitus, symbolic violence and misrecognition to explore teachers’ and students’ experiences in order to determine the extent to which power and privilege begin to be challenged within participating schools. We explore the ways in which teacher habitus has shifted to recognize, include or become empathetic to student habitus as a result of Project ARTS curricula, co-teaching and professional development while also considering the possibility the program produces unintended consequences at odds with the project’s mission: reproducing the status quo by advancing the cultural capital of teachers rather than that of students. Finding markedly fewer teacher narratives confirming the social reproduction of inequitable power relationships than when the project began, we conclude by discussing the transformation of teacher habitus, student outcomes, and school climate after 5 years of Project ARTS participation, proposing implications for urban teachers and leaders, their communities, and policymakers intent upon implementing equitable educational reform and the social transformation reform intends.     

“Do I Really Belong Here?”: The Stigma of Being a Community College Transfer Student at a Four-Year University

ABSTRACT

Students who begin their educational journeys in community college face many obstacles trying to complete their bachelor’s degrees. Much research has been dedicated to identifying academic factors that predict successful transfer and degree attainment, but relatively little research investigates how the community college experience affects these students once enrolled at the four-year university. Here, we present the results of a qualitative study that explored the challenges faced by 14 community college students during and after transfer. Specifically, we focus on student reports of a sense of stigma from having attended community college and how students overcame these feelings. Recommendations are provided for how community colleges and four-year universities can better equip their students with the knowledge and resources to combat this perception of stigma.     

Childhood Maltreatment and Early Developmental Vulnerabilities at Age 5 Years

This study examined associations between maltreatment and early developmental vulnerabilities in a population sample of 68,459 children (M_age = 5.62 years, SD = .37) drawn from the Australian state of New South Wales, using linked administrative data for the children and their parents (collected 2001–2009). Associations were estimated between (a) any maltreatment, (b) the number of maltreatment types, and (c) the timing of first reported maltreatment and vulnerability and risk status on multiple developmental domains (i.e., physical, social, emotional, cognitive, and communication). Pervasive associations were revealed between maltreatment and all developmental domains; children exposed to two or more maltreatment types, and with first maltreatment reported after 3 years of age, showed greater likelihood of vulnerability on multiple domains, relative to nonmaltreated children.     

When genres meet: Inquiry into a sixth‐grade urban science class

In this study, we explore oral and written work (plays and rap songs) of students in a sixth‐grade all African‐American urban science class to reveal ways affective and social aspects are intertwined with students' cognition. We interpret students' work in terms of the meeting of various genres brought by the students and teachers to the classroom. Students bring youth genres, classroom genres that they have constructed from previous schooling, and perhaps their own science genres. Teachers bring their favored classroom and science genres. We show how students' affective reactions were an integral part of their constructed scientific knowledge. Their knowledge building emerged as a social process involving a range of transactions among students and between students and teacher, some transactions being relatively smooth and others having more friction. Along with their developing science genre, students portrayed elements of classroom genres that did not exist in the classroom genre that the teacher sought to bring to the class. Students' work offered us a glimpse of students' interpretations of gender dynamics in their classrooms. Gender also was related to the particular ways that students in that class included disagreement in their developing science genre. © 2002 Wiley Periodicals, Inc.

Physiological characteristics of successful mountain bikers and professional road cyclists

The aims of this study were to compare the physiological and anthropometric characteristics of successful mountain bikers and professional road cyclists and to re-examine the power-to-weight characteristics of internationally competitive mountain bikers. Internationally competitive cyclists (seven mountain bikers and seven road cyclists) completed the following tests: anthropometric measurements, an incremental cycle ergometer test and a 30 min laboratory time-trial. The mountain bikers were lighter (65.3+/-6.5 vs 74.7+/-3.8 kg, P= 0.01; mean +/- s) and leaner than the road cyclists (sum of seven skinfolds: 33.9+/-5.7 vs 44.5+/-10.8 mm, P = 0.04). The mountain bikers produced higher power outputs relative to body mass at maximal exercise (6.3+/-0.5 vs 5.8+/-0.3 W x kg(-1), P= 0.03), at the lactate threshold (5.2+/-0.6 vs 4.7+/-0.3 W x kg(-1), P= 0.048) and during the 30 min time-trial (5.5+/-0.5 vs 4.9+/-0.3 W x kg(-1), P = 0.02). Similarly, peak oxygen uptake relative tobody mass was higher in the mountain bikers (78.3+/-4.4 vs 73.0+/-3.4 ml x kg(-1) x min(-1), P = 0.03). The results indicate that high power-to-weight characteristics are important for success in mountain biking. The mountain bikers possessed similar anthropometric and physiological characteristics to previously studied road cycling uphill specialists.     

Three recommended inclusive language guidelines for scholarly publishing: Words matter

• Inclusive language will make scholarly publishing more accurate and more respectful, and it has the potential to help authors reach a wider audience.
• JAMA and the JAMA Network journals, the American Chemical Society and the Coalition for Diversity and Inclusion in Scholarly Communications have free guides on inclusive language, formatting and images.
• The guides provide principles and rationale, as well as examples of preferred language, in order to equip people with knowledge to choose the most inclusive words even as terminology preferences change.
