What really makes students like a web site? What are the implications for designing web-based language learning sites?
Faced with reduced numbers choosing to study foreign languages (as in England and Wales), strategies
to create and maintain student interest need to be explored. One such strategy is to create
âtasterâ courses in languages, for potential university applicants. The findings presented arise from
exploratory research, undertaken to inform the design of a selection of web-based taster courses for
less widely taught languages. 687 school students, aged 14-18, were asked to identify a web site that
they liked and to state their main reason for liking it. They were invited to include recreational sites
and told that their answers could help with web design for the taster courses. To explore the reasons,
two focus groups were conducted and student feedback on the developing taster course site was collected.
Students nominated search engines and academic sites, sites dedicated to hobbies, enthusiasms,
youth culture and shopping. They liked them for their visual attributes, usability, interactivity,
support for schoolwork and for their cultural and heritage associations, as well as their content
and functionality. They emerged as sensitive readers of web content, visually aware and with clear
views on how text should be presented. These findings informed design of the taster course site.
They are broadly in line with existing design guidelines but add to our knowledge about school studentsâ
use of the web and about designing web-based learning materials. They may also be relevant
to web design at other levels, for example for undergraduates
The cost of paediatric obesity
There has been a great deal of media attention given to the rising levels of obesity
and overweight in children and adolescents, but what is the real cost of pediatric obesity?
This article reviews information about the recent rise in pediatric obesity and discusses
the cost of this condition from medical, financial and psychological perspectives
Unfolding sustainability transitions in food systems: insights from UK and French trajectories.
While the negative environmental, social and health impacts of the current food system have been acknowledged and evidenced for several decades, the recent and current transformations in food systems at diverse scales are not yet addressing the many inter-related stakes at play. Due to the much wider set of interactions in this consumption-production system, new conceptual tools are required for understanding and assessing sustainability transitions and what prevents them. The article will draw on the cases of France and the UK to examine these countriesâ national food systemsâ historical trajectories and suggest a periodization of these in order to reveal common characteristics and differences. This will show that despite common major trends and common transition or inertia mechanisms, pathways differ, especially from the 1990s, due to different configurations of power relationships between the state, economic actors and civil society in a context of an increasing competition between sustainability narratives that leads to an increasing fragmentation in food systems. It will lead us to join the recent progress in the sustainability transitionsâ community towards a shift in the analysis from a focus on nichesâ trajectories and effects to a deeper focus on power configurations and competing narratives, as well as to suggest a larger inclusion of socio-ecological and spatial dimensions
Ante-Autobiography and the Archive of Childhood
This essay examines the concept of childrenâs autobiography via several autobiographical extracts
written by the author as a child. Although only a small proportion of people will compose and
publish a full-length autobiography, almost everyone will, inadvertently, produce an archive of
the self, made from public records and private documents. Here, such works are seen as providing
access to writing both about and by children. The essay explores the ethics and poetics of
childrenâs writing via the key debates in life writing; in particular, the dynamic relationship
between adults and children, both as distinct stages of life and dual parts of one autobiographical
identity. The term âante-autobiographyâ is coined to refer to these texts which come before or
instead of a full-length narrative. They are not read as less than or inadequate versions of
autobiography, but rather as transgressive and challenging to chronological notions of the genre
Vision Screening Assessment (VISA) tool: diagnostic accuracy validation of a novel screening tool in detecting visual impairment among stroke survivors
PURPOSE:Screening for visual problems in stroke survivors is not standardised. Visual problems that remain undetected or poorly identified can create unmet needs for stroke survivors. We report the validation of a new Vision Impairment Screening Assessment (VISA) tool intended for use by the stroke team to improve identification of visual impairment in stroke survivors. METHODS:We conducted a prospective case cohort comparative study in four centres to validate the VISA tool against a specialist reference vision assessment. VISA is available in print or as an app (Medicines and Healthcare products Regulatory Agency regulatory approved); these were used equally for two groups. Both VISA and the comprehensive reference vision assessment measured case history, visual acuity, eye alignment, eye movements, visual field and visual inattention. The primary outcome measure was the presence or absence of visual impairment. RESULTS:Two hundred and twenty-one stroke survivors were screened. Specialist reference vision assessment was by experienced orthoptists. Full completion of screening and reference vision assessment was achieved for 201 stroke survivors. VISA print was completed for 101 stroke survivors; VISA app was completed for 100. Sensitivity and specificity of VISA print was 97.67% and 66.67%, respectively. Overall agreement was substantial; K=0.648. Sensitivity and specificity of VISA app was 88.31% and 86.96%, respectively. Overall agreement was substantial; K=0.690. Lowest agreement was found for screening of eye movement and near visual acuity. CONCLUSIONS:This validation study indicates acceptability of VISA for screening of potential visual impairment in stroke survivors. Sensitivity and specificity were high indicating the accuracy of this screening tool. VISA is available in print or as an app allowing versatile uptake across multiple stroke settings
Detection of prions in the faeces of sheep naturally infected with classical scrapie
Classical scrapie is a naturally transmitted prion disease of sheep and goats. Contaminated environments may contribute to the spread of disease and evidence from animal models has implicated urine, blood, saliva, placenta and faeces as possible sources of the infection. Here we sought to determine whether sheep naturally infected with classical scrapie shed prions in their faeces. We used serial protein misfolding cyclic amplification (sPMCA) along with two extraction methods to examine faeces from sheep during both the clinical and preclinical phases of the disease and showed amplification of PrPSc in 7 of 15 and 14 of 14 sheep respectively. However PrPSc was not amplified from the faeces of 25 sheep not exposed to scrapie. These data represent the first demonstration of prion shedding in faeces from a naturally infected host and thus a likely source of prion contamination in the environment
