Early changes in Achilles tendon behaviour in vivo following downhill backwards walking

Downhill backwards walking causes repeated, cyclical loading of the muscle–tendon unit. The effect this type of repeated loading has on the mechanical behaviour of the Achilles tendon is presently unknown. This study aimed to investigate the biomechanical response of the Achilles tendon aponeurosis complex following a downhill backwards walking protocol. Twenty active males (age: 22.3 ± 3.0 years; mass: 74.7 ± 5.6 kg; height: 1.8 ± 0.7 m) performed 60 min of downhill (8.5°), backwards walking on a treadmill at ?0.67 m · s^?1. Data were collected before, immediately post, and 24-, 48- and 168-h post-downhill backwards walking. Achilles tendon aponeurosis elongation, strain and stiffness were measured using ultrasonography. Muscle force decreased immediately post-downhill backward walking (P = 0.019). There were increases in Achilles tendon aponeurosis stiffness at 24-h post-downhill backward walking (307 ± 179.6 N · mm^?1, P = 0.004), and decreases in Achilles tendon aponeurosis strain during maximum voluntary contraction at 24 (3.8 ± 1.7%, P = 0.008) and 48 h (3.9 ± 1.8%, P = 0.002) post. Repeated cyclical loading of downhill backwards walking affects the behaviour of the muscle–tendon unit, most likely by altering muscle compliance, and these changes result in tendon stiffness increases.     

Validity and repeatability of a depth camera-based surface imaging system for thigh volume measurement

Complex anthropometrics such as area and volume, can identify changes in body size and shape that are not detectable with traditional anthropometrics of lengths, breadths, skinfolds and girths. However, taking these complex with manual techniques (tape measurement and water displacement) is often unsuitable. Three-dimensional (3D) surface imaging systems are quick and accurate alternatives to manual techniques but their use is restricted by cost, complexity and limited access. We have developed a novel low-cost, accessible and portable 3D surface imaging system based on consumer depth cameras. The aim of this study was to determine the validity and repeatability of the system in the measurement of thigh volume. The thigh volumes of 36 participants were measured with the depth camera system and a high precision commercially available 3D surface imaging system (3dMD). The depth camera system used within this study is highly repeatable (technical error of measurement (TEM) of <1.0% intra-calibration and ~2.0% inter-calibration) but systematically overestimates (~6%) thigh volume when compared to the 3dMD system. This suggests poor agreement yet a close relationship, which once corrected can yield a usable thigh volume measurement.     

Changing the Library Brand: A Case Study

ABSTRACT

This article outlines some of the opportunities and challenges of changing what the library “brand” means to academic and professional services staff in the rapidly changing environment of UK higher education, taking the University of Leicester as a case study. It makes a practitioner contribution to the growing body of evidence of how libraries are extending their role and how their customers are responding. It begins by considering the drivers for change in the higher education and scholarly information environments and how these are influencing the development of library services at the University of Leicester. The topics considered include researcher development, Digital Humanities, Open Access, independent learning, and curating the university's own information assets. The impact of these developments is outlined and how an evolving approach to strategic marketing is beginning to change perceptions as the boundaries of the library's role extend.     

Do conservators dream of electric sheep? Replicas and replication

The paper crosses the boundaries between different genres, drawing on key material and emphasising the philosophical challenges around decision-making and values in relation to replication and replicas. In 1968, Philip K. Dick wrote the book Do Androids Dream of Electric Sheep? which became the inspiration for the 1982 film Bladerunner. The book is set in Los Angeles in a post-apocalyptic future where mankind has left Earth, resulting in androids being created to develop new ‘off-world’ colonies. The book and film create a novel and interesting framework to discuss the subject of replicas and replication within contemporary conservation practice. Key themes are decay promoting replication, original versus replica, creating empathy in replication. The debate focuses on the case study of Naum Gabo's Construction in Space (Crystal) of 1937–39; which was the sculpture replicated in the most recent replication project at Tate, completed in July 2015.     

Moving from best practice to next practice: some deliberations on educational leadership

This paper begins from the premise that the challenges characterising the contemporary education environment call for more flexible approaches to leadership than the traditional reliance on codified knowledge. These more flexible approaches are likely to involve new ways of learning, dispositions and behaviours, which enable educational leadership to progress from ‘best practice’ to ‘next practice’. The paper, therefore, has two main aims. First, it seeks to illuminate a potential modus operandi for contending with the complex challenges that have become integral to the landscape of educational leadership. Second, it seeks to encourage consideration of the implications of this modus operandi for processes of leadership thinking, learning and development. For this purpose, the nature of the challenges purported to define the landscape of educational leadership now and into the future is first discussed. This is followed by an examination of three interrelated leadership concepts in enabling appropriate judgements to be made in dealing effectively with highly complex circumstances, namely, ‘phronesis’, ‘contextual intelligence’ and ‘negative capability’. The paper concludes by discussing the circumstances within the professional milieu that either constrain or promote the kind of educational leadership that is deemed to be required for embracing the three concepts in question.     

Conceptualizing impact in academic development: finding a way through

This paper explores the notion of impact in the context of academic development programs and considers how it can be described and understood. We argue that impact has a range of meanings and academic development programs such as graduate certificates have a broad group of stakeholders and hence the impact is different for each group depending on how the program aims and objectives are defined and understood. In finding a way through the difficulties of evaluating impact in academic development we point to the importance of clearly conceptualizing the notion of impact, a careful identification of the assumptions underpinning any program and an understanding of who academic development will benefit and how. We suggest that impact in academic development cannot be understood without taking account of the range of possible impacts and the difficulty of attributing simple cause and effect to a complex environment.     

Characteristics of Effective In‐service Programmes and Activities: results of a Dutch survey

The goal of this study is to determine which features effective in‐service activities must have, and to what extent designers of in‐service activities take these features into account. The study is also directed at the relationship between these features of in‐service activities and their implementation and impact characteristics. On the basis of a Delphi‐study, a survey was carried out among teachers, principals, in‐service education and training (INSET) trainers and school counsellors. This article presents the data gathered on programme participants’ and trainers’ opinions and beliefs about effective in‐service and about implementation and impact characteristics. The study also examines the extent of the oft reported critical comments on in‐service activities. In spite of extensive criticism about the value of in‐service education, most participants are positive about the design and execution of the activities. However, INSET has to be closely watched for effectiveness, especially where it concerns applicability and functionality. This is generally judged to be insufficient.
