Establishing Influential Decision Making Factors for University Library Opening Hours: An Exploratory UK Regional Study

Many factors and pressures affect decisions made in UK university libraries on opening hours especially 24/7. This article reports on a project to examine the decision making process, influential factors, and stakeholders. A workshop for senior library managers in the East Midlands was held to gather data and share experiences. From analysis of the workshop a framework of influential factors was devised and the decision making process was examined. Although each library had different priorities, important factors overall included pressure from undergraduates and the student's union, and provision during exam periods. Further research to examine the framework nationally is required.     

Physical Activity,Self-Regulation,and Early Academic Achievement in Preschool Children

Research Findings: The present study investigated whether active play during recess was associated with self-regulation and academic achievement in a prekindergarten sample. A total of 51 children in classes containing approximately half Head Start children were assessed on self-regulation, active play, and early academic achievement. Path analyses indicated that higher active play was associated with better self-regulation, which in turn was associated with higher scores on early reading and math assessments. Practice or Policy: Results point to the benefits of active play for promoting self-regulation and offer insight into possible interventions designed to promote self-regulation and academic achievement.     

The Medical School Learning Environment Survey: an examination of its factor structure and relationship to student performance and satisfaction

The Medical School Learning Environment Survey (MSLES) was used with a sample of 311 undergraduate medical students in British Columbia, Canada, to assess the seven scales of Medical Breadth of Interest, Personal Breadth of Interest, Emotional Climate, Flexibility, Meaningful Learning Experience, Organization, Nurturance and Student–Student Interaction. Confirmatory factor analysis was used to support the validity of the MSLES when used with this sample.     

Thiolene-based microfluidic flow cells for surface plasmon resonance imaging

Thiolene-based microfluidic devices have been coupled with surface plasmon resonance imaging (SPRI) to provide an integrated platform to study interfacial interactions in both aqueous and organic solutions. In this work, we develop a photolithographic method that interfaces commercially available thiolene resin to gold and glass substrates to generate microfluidic channels with excellent adhesion that leave the underlying sensor surface free from contamination and readily available for surface modification through self-assembly. These devices can sustain high flow rates and have excellent solvent compatibility even with several organic solvents. To demonstrate the versatility of these devices, we have conducted nanomolar detection of streptavidin-biotin interactions using in situ SPRI.     

Use of biochemical parameters for non-invasive screening of oesophageal varices in comparison to elastography-based approach in patients with compensated advanced chronic liver disease

IntroductionOesophageal varices are routinely diagnosed by esophagogastroduodenoscopy (EGD), and their bleeding has high mortality. We aimed to evaluate diagnostic performance of biochemical tests in comparison to elastography-based approaches, as non-invasive alternatives to EGD, for ruling-out high risk oesophageal varices (HRV).Material and methodsRetrospective analysis of patients (N = 861) who underwent liver stiffness measurement (LSM) by transient elastography (TE) in a single centre over 5-year period, with available results of EGD (within 3 months from LSM). Only patients with suspicion of compensated advanced chronic liver disease (cACLD) defined by LSM ≥ 10 kPa were included comprising the final cohort of 73 subjects. Original and expanded Baveno VI criteria (B6C), controlled attenuation parameter (CAP), platelet count (PLT), aspartate aminotransferase to PLT ratio index (APRI), Fibrosis-4 index (FIB4), model for end stage liver disease (MELD) score were evaluated against the results of EGD that served as the reference method.ResultsAnalysed patients had median age 62 years, 59/73 (0.81) were males, 54/73 (0.74) had alcoholic/non-alcoholic fatty liver disease, and 21/73 (0.29) had HRV. In multivariate logistic regression analysis only LSM and PLT were independently associated with HRV. The best performing tests for ruling-out HRV (% of spared EGD; % of missed HRV) were respectively: LSM < 20 kPa (53.4%; 0%), B6C (38%; 0%), Expanded B6C (47.9%; 4.8%); PLT > 214x10⁹/L (21.9%; 0%); FIB4 ≤ 1.8 (21.4%; 0%), APRI ≤ 0.34 (12.3%; 0%). CAP, MELD = 6 alone or combined with PLT > 150(x10⁹/L) did not show acceptable performance.ConclusionThe best performing biochemical tests for ruling-out HRV in our cohort of patients were PLT and FIB-4, but they were still outperformed by elastography-based approaches.Keyword: portal hypertension, cirrhosis, platelet count, esophageal varices, non-invasive tests     

Stress, Burnout and Workload in Teachers of Children with Special Educational Needs

Whilst stress in teaching has received much attention in recent years, for teachers of children with special educational needs (SEN) specific stress-related research is relatively rare. This study sought to address this issue by investigating stress, burnout and workload in teachers of children with special educational needs. A postal questionnaire was sent to 56 ordinary schools and eight schools for children with moderate learning difficulties (MLD), eight for children with severe learning difficulties (SLD) and eight for children with emotional and behavioural difficulties (EBD). The schools were situated in inner city, urban and rural areas in the south-east of England. A total of 221 teachers responded. Results indicated that, whilst generalised claims for burnout may not be justified, within all three special school settings there was evidence of a high level of emotional exhaustion as measured by the education version of the Maslach Burnout Inventory (MBI). In addition, all groups were subject to long hours of work, and work overload was high for ordinary school SEN teachers and teachers working in MLD and SLD settings. Reference to sources of intense stress indicated some differences according to setting but generally implicated workload and challenging behaviour. The conclusions are that further research into stress and burnout of SEN teachers is required if effective coping and preventative strategies are to be designed.     

The Training and Professional Development of School Leaders in Europe

The article reviews the activities that have been taking place in Europe in the field of senior staff training, particularly headteacher training, based on a study undertaken by the author in 1980 in Norway, Sweden, Denmark, the Netherlands and France. It goes on to consider some of the underlying problems and some major areas of study that require further examination, i.e. it is difficult to define the job to be undertaken by the trainer; to analyse the nature of the organisation and school system in which he works; to identify ‘leadership'; to provide relevant training and to then evaluate that training and its real impact on the school and on the quality, effectiveness and relevance of education offered to pupils and students.

Finally it describes some of the possibilities for fruitful cooperation and collaboration over the next few years through the efforts of a wide variety of international organisations.

Cet article fait un tour d'horizon des actions qui ont été entreprises en Europe dans le domaine de la formation des directeurs d'établissement et des maîtres chargés d'une responsabilité particulière dans l'enseignement. Il s'appuie sur une étude entreprise par l'auteur au Danemark, en France, en Norvège et dans les Pays‐Bas en 1980.

L'article étudie ensuite certains problèmes fondamentaux et quelques grands sujets d'étude qui demandent une analyse plus poussée: par exemple la difficulté à définir le travail que doit entreprendre le formateur, pour analyser la nature de l'organisation du système scolaire dans lequel il travaille, la difficulté à identifier les fonctions de ‘leadership’, à etablir une formation appropriée, puis à évaluer cette formation et son impact réel sur l'école et sur la qualité, enfin l'efficacité et l'appropriation de l'enseignement qui est offert aux élèves et étudiants.

Finalement, l'auteur expose quelques possibilités de collaboration fructueuse pour les prochaines années grâce aux efforts de différentes organisations internationales.     

Generalizability in Item Response Modeling

An approach called generalizability in item response modeling (GIRM) is introduced in this article. The GIRM approach essentially incorporates the sampling model of generalizability theory (GT) into the scaling model of item response theory (IRT) by making distributional assumptions about the relevant measurement facets. By specifying a random effects measurement model, and taking advantage of the flexibility of Markov Chain Monte Carlo (MCMC) estimation methods, it becomes possible to estimate GT variance components simultaneously with traditional IRT parameters. It is shown how GT and IRT can be linked together, in the context of a single-facet measurement design with binary items. Using both simulated and empirical data with the software WinBUGS, the GIRM approach is shown to produce results comparable to those from a standard GT analysis, while also producing results from a random effects IRT model.
