Cleaning up the catalogue
The London School of Economics wanted to remove cataloguing inconsistencies but the scale of the task was huge, and outsourcing to a specialist bibliographic services company proved only a partial solution. Helen Williams explains why manual and automated processes were needed
The metabolic responses to high carbohydrate meals with different glycemic indices consumed during recovery from prolonged strenuous exercise
This study investigated the metabolic responses to high glycemic index (HGI) or low glycemic index (LGI) meals consumed during recovery from prolonged exercise. 8 trained male athletes undertook 2 trials. Following an overnight fast, subjects completed a 90 minute run. Meals were provided 30 minutes and 2 hours following cessation of exercise. The plasma glucose responses to both meals were greater in the HGI trial compared to the LGI trial. Following breakfast, there were no differences in the serum insulin concentrations between the trials; however, following lunch, concentrations were higher in the HGI trial compared to the LGI trial. This suggests that the glycemic index of the carbohydrates consumed during the immediate post-exercise period might not be important as long as sufficient carbohydrate is consumed. The high insulin concentrations following a HGI meal later in the recovery period could facilitate further muscle glycogen resynthesis
Using wikis for online group projects: student and tutor perspectives
This paper presents a study of the use of wikis to support online group projects in two courses at the UK Open University. The research aimed to investigate the effectiveness of a wiki in supporting (i) student collaboration and (ii) tutors’ marking of the students’ collaborative work. The paper uses the main factors previously identified by the technology acceptance model (TAM) as a starting point to examine and discuss the experiences of these two very different user groups: students and tutors. Data was gathered from students via a survey and from tutors via a range of methods. The findings suggest that, when used in tandem with an online forum, the wiki was a valuable tool for groups of students developing a shared resource. As previous studies using the TAM have shown, usefulness and ease of use were both important to students’ acceptance of the wiki. However, the use of a wiki in this context was less well-received by tutors, because it led to an increase in their workload in assessing the quality of students’ collaborative processes. It was possible to reduce the tutor workload by introducing a greater degree of structure in the students’ tasks. We conclude that when introducing collaborative technologies to support assessed group projects, the perceptions and needs of both students and tutors should be carefully considered

Whole-school mental health promotion in Australia
Although there is increasing recognition internationally of the significance of social and
emotional health and wellbeing for the healthy development of young people, the levels
of support that governments provide for mental health policy and programme initiatives
vary widely. In this paper, consideration is given to Australia’s approach to mental
health promotion from early years to secondary school, including specific reference to
the KidsMatter Primary mental health promotion, prevention and early intervention
initiative. Although it is now well established that schools provide important settings for
the promotion of mental health initiatives, there are significant challenges faced in
effectively implementing and maintaining the delivery of evidence-based practice in
school settings, including concerns about quality assurance in processes of
implementation, translation, dissemination and evaluation.peer-reviewe
Managing LTL properties in Event-B refinement
Refinement in Event-B supports the development of systems via proof based
step-wise refinement of events. This refinement approach ensures safety
properties are preserved, but additional reasoning is required in order to
establish liveness and fairness properties.
In this paper we present results which allow a closer integration of two
formal methods, Event-B and linear temporal logic. In particular we show how a
class of temporal logic properties can carry through a refinement chain of
machines. Refinement steps can include introduction of new events, event
renaming and event splitting. We also identify a general liveness property that
holds for the events of the initial system of a refinement chain. The approach
will aid developers in enabling them to verify linear temporal logic properties
at early stages of a development, knowing they will be preserved at later
stages. We illustrate the results via a simple case study
Design for Wire + Arc Additive Manufacture: design rules and build orientation selection
Wire + Arc Additive Manufacture (WAAM) is an additive manufacturing technology that can produce near net-shape parts layer by layer in an automated manner using welding technology controlled by a robot or CNC machine. WAAM has been shown to produce parts with good structural integrity in a range of materials including titanium, steel and aluminium and has the potential to produce high value structural parts at lower cost with much less waste material and shorter lead times that conventional manufacturing processes.
This paper provides an initial set of design rules for WAAM and presents a methodology for build orientation selection for WAAM parts. The paper begins with a comparison between the design requirements and capabilities of WAAM and other additive manufacturing technologies, design guidelines for WAAM are then presented based on experimental work. A methodology to select the most appropriate build orientation for WAAM parts is then presented using a multi attribute decision matrix approach to compare different design alternatives. Two aerospace case study parts are provided to illustrate the methodology
Entrepreneurial Experiences of Becoming an Employer: An Interpretative Phenomenological Analysis
The aim of this study is to better understand how entrepreneurs become employers. Taking a phenomenological position, my research uses a co-creative methodology to explore transitions from entrepreneur to entrepreneur-employer. Job creation is commonly cited as a benefit of entrepreneurship (Birch, 1979; Acs, 2006), yet little is known about the transition to entrepreneur-employer. Recent estimates highlight that many UK enterprises are classified as non-employing businesses, comprising the founder only (ONS, 2020). This suggests that while a high proportion of individuals enter self-employment, growth presents a significant challenge for many (Coad et al., 2017). Extant research investigating the entrepreneur to entrepreneur-employer transition is predominantly functionalist, reinforcing commonly held beliefs that entrepreneurship is a desirable economic activity (DvouletĂ˝, 2018). In response, I sought to apply a qualitative approach. Using Interpretative Phenomenological Analysis (IPA) as a guiding framework, I explore the lived experiences of six female and four male entrepreneur-employers in South Wales. My contribution to the entrepreneurship field is twofold. Firstly, my findings reflect an uglier reality to job-creation than is readily visible in the mainstream entrepreneurship literature. Perceiving it as a double-edged sword, participants juxtaposed common entrepreneurial narratives against their everyday realties. Becoming an employer introduced a level of relationality, exposing participants to systems demanding conformity rather than entrepreneurial diversity. Second, methodologically I demonstrate how the use of a co-creative method is a valuable tool for accessing complex and nuanced entrepreneurial experiences. Participants universally expressed frustration at being suspended in what I interpret as a liminal state. Drawing on relevant literature, I theorise that this is particularly felt within neoliberal post-industrial contexts. I conclude that, for my participants, negotiating the gap between mainstream entrepreneurial narratives, and their lived entrepreneurial experiences, was a significant factor in moving beyond the critical entrepreneur to entrepreneur-employer transition
