Scaling Within Rather Than Scaling Up: Implications from Students' Experiences in Reforming Urban Middle Schools

This article uses urban middle school student's interviews to describe the instructional differences they faced each day and the effects of these differences on what they learned. Data from a cohort of nearly 200 students over two years revealed common definitions of how they wanted their teachers to act and the kinds of classroom activities they wanted to be engaged in. But more important, their observations revealed stark differences in their actual experiences. Too few students experienced the quality instruction they desired. Students praised teachers who were willing to help, were strict but nice, and were able to explain. They also wanted instructional settings where they were challenged by meaningful projects and experiments, worked more interdependently with their peers, and combined work with fun. We conclude from these student observations that reform efforts will be more successful in settings that nurture, maintain, and reinforce classrooms like those so aptly described by students and promote the spread of these classrooms by taking advantage of the talents of exemplary staff within buildings (i.e., scaling within).     

The influence of Ministry of Defence funding on semiconductor research and development in the United Kingdom

This paper argues that the United Kingdom Ministry of Defence's (MoD) sponsorship of industrial semiconductor research and development (R&D) has, by its very nature, influenced the type of R&D performed, and the directions it has taken, to the extent of limiting its potential for subsequent commercial utilization. While much of the fault appears to lie with the semiconductor industry's response to MoD funding of its R&D, especially its over-reliance on such external support, the paper also suggests that the structure, modus operandi, and funding mechanisms of the MoD department concerned have significantly affected the industry's R&D activities. With these criticisms in mind, while at the same time noting the advantageous features of this department's activities, such as its relative autonomy, brief suggestions for ensuring more coherent and continuous state support for semiconductor R&D, including, for example, the use of innovation-oriented procurement policies, are offered.     

Implementing and Assessing Library Reference Training Programs

Comprehensive assessments have shown that academic library users prefer a welcoming environment that provides the opportunity for self-sufficiency. Libraries need to meet these expectations and improve the quality of library reference by creating a comprehensive training program for librarians, staff, and students. This article will review standards for reference training in academic libraries with a focus on one-desk service points and consider best practices for planning, implementing, and assessing training programs for staff, students, and librarians.     

Reinvention,Revolution and Revitalization: Real Life Tales from Publishing’s Front Lines

Over the past 10 years the publishing industry has undergone major changes with the shift from format driven print publishing to the dynamic delivery of information to users in a variety of digital and printed formats. These changes have affected all aspects of the publishing business including the technology platforms and product development processes. This paper will survey these areas and discuss (1) The principals of the information delivery platforms powering the new generation of products; (2) Strategies for innovation and product development including; (a) Innovation Hubs: enabling new products while maintaining the core; (b) Data driven publishing: the complete picture of your users and markets; (c) Contextual delivery to better deliver information beyond the traditional touch points of publishing and research. These strategies will allow publishing and information provider organizations to reinvent themselves in the continuing digital revolution and are key to bringing new vitality to the ever-changing role of publisher and information provider.     

Microfluidic culture platform for studying neuronal response to mild to very mild axonal stretch injury

A new model for studying localised axonal stretch injury is presented, using a microfluidic device to selectively culture axons on a thin, flexible poly (dimethylsiloxane) membrane which can be deflected upward to stretch the axons. A very mild (0.5% strain) or mild stretch injury (5% strain) was applied to primary cortical neurons after 7 days growth in vitro. The extent of distal degeneration was quantified using the degenerative index (DI, the ratio of fragmented axon area to total axon area) of axons fixed at 24 h and 72 h post injury (PI), and immunolabelled for the axon specific, microtubule associated protein-tau. At 24 h PI following very mild injuries (0.5%), the majority of the axons remained intact and healthy with no significant difference in DI when compared to the control, but at 72 h PI, the DI increased significantly (DI = 0.11 ± 0.03). Remarkably, dendritic beading in the somal compartment was observed at 24 h PI, indicative of dying back degeneration. When the injury level was increased (5% stretch, mild injury), microtubule fragmentation along the injured axons was observed, with a significant increase in DI at 24 h PI (DI = 0.17 ± 0.02) and 72 h PI (DI = 0.18 ± 0.01), relative to uninjured axons. The responses observed for both mild and very mild injuries are similar to those observed in the in vivo models of traumatic brain injury, suggesting that this model can be used to study neuronal trauma and will provide new insights into the cellular and molecular alterations characterizing the neuronal response to discrete axonal injury.     

Database choices in endocrine systematic reviews

Objective

The choice of bibliographic database during the systematic review search process has been an ongoing conversation among information specialists. With newer information sources, such as Google Scholar and clinical trials registries, we were interested in which databases were utilized by information specialists and systematic review researchers.

Method

We retrieved 144 systematic reviews and meta-analyses from 4 clinical endocrinology journals and extracted all information sources used during the search processes.

Results

Findings indicate that traditional bibliographic databases are most often used, followed by regional databases, clinical trials registries, and gray literature databases.

Conclusions

This study informs information specialists about additional resources that may be considered during the search process.     

The development of a method for identifying penalty kick strategies in association football

Penalty takers in association football adopt either a keeper-independent or a keeper-dependent strategy, with the benefits of the keeper-independent strategy presumed to be greater. Yet, despite its relevance for research and practitioners, thus far no method for identifying penalty kick strategies has been available. To develop a validated and reliable method, Experiment 1 assessed characteristics that observers should use to distinguish the two strategies. We asked participants to rate 12 characteristics of pre-recorded clips of kicks of penalty takers that used either a keeper-independent or keeper-dependent strategy. A logistic regression model identified three variables (attention to the goalkeeper, run-up fluency and kicking technique) that in combination predicted kick strategy in 92% of the penalties. We used the model in Experiment 2 to analyse prevalence and efficacy of both the strategies for penalty kicks in penalty shoot-outs during FIFA World Cups (1986–2010) and UEFA Football Championships (1984–2012). The keeper-independent strategy was used much more frequently (i.e., 78–86%) than the keeper-dependent strategy, but successes did not differ. Penalty takers should use both the strategies to be less predictable. Goalkeepers can use the developed model to improve their chances to succeed by adjusting their behaviour to penalty takers’ preferred penalty kick strategy.
