ABSTRACTLight sensitive objects will fade on display. Collection managers and curators face the dilemma whether to spread fading over several similar objects or sacrifice one. This paper describes an experiment in which participants were asked how they would want to pass on a collection of seventeenth century hand-coloured maps to coming generations. Results show that while colour changes are hardly visible, both public and professionals do not perceive them as damage and prefer to spread fading. Once fading becomes clearly visible in all maps, the preference shifts to sacrificing one map. The tipping point lies around five just noticeable changes. This information can be used when selecting objects for exhibition. The outcome also implies it would be prudent to assess the degree of fading of much exhibited objects and consider whether and when to choose for a sacrifice strategy. 相似文献

The paper considers how attributes and skills fundamental to the information profession may be applied to the development and management of Web-based services and resources. It also looks at the need for the acquisition of new skills as part of a continuing professional development programme. The report considers the changing role of the Webmaster and the implications this might have in terms of the role of information professionals. To offer a practical example, from within the healthcare sector, the article goes on to describe the development of BMA Library Online. This is the BMA Library's own suite of Web-based information services and resources for personal members, institutional members and staff. The library's own Web team has been responsible for the development and maintenance of BMA Library Online. To conclude, the paper looks forward to future possibilities for information professionals as Web developers and at how this might be influenced by changes in the Webmaster role. It is crucial that skills and expertise are shared as the roles that go to make up a Webmaster or Webmaster team continue to merge and evolve, and with the possible wider distribution of provision of Web content within organizations. 相似文献

Visual field biases have been identified as markers of atypical lateralization in children with developmental conditions, but this is the first investigation to consider early lateralized gaze behaviors for social stimuli in preterm infants. Eye-tracking methods with 51 preterm (33 male, 92.1% White) and 61 term-born (31 male, 90.1% White) infants aged 8–10 months from Edinburgh, UK, captured the development of visual field biases, comparing gaze behavior to social and non-social stimuli on the left versus right of the screen. Preterm infants showed a significantly reduced interest to social stimuli on the left versus right compared to term children (d = .58). Preterm children exhibit early differential orienting preferences that may be an early indicator of atypical lateralized function. 相似文献

Embryoid body (EB) formation forms an important step in embryonic stem cell differentiation invivo. In murine embryonic stem cell (mESC) cultures EB formation is inhibited by the inclusion of leukaemic inhibitory factor (LIF) in the medium. Assembly of mESCs into aggregates by positive dielectrophoresis (DEP) in high field regions between interdigitated oppositely castellated electrodes was found to initiate EB formation. Embryoid body formation in aggregates formed with DEP occurred at a more rapid rate-in fact faster compared to conventional methods-in medium without LIF. However, EB formation also occurred in medium in which LIF was present when the cells were aggregated with DEP. The optimum characteristic size for the electrodes for EB formation with DEP was found to be 75-100 microns; aggregates smaller than this tended to merge, whilst aggregates larger than this tended to split to form multiple EBs. Experiments with ESCs in which green fluorescent protein (GFP) production was targeted to the mesodermal gene brachyury indicated that differentiation within embryoid bodies of this size may preferentially occur along the mesoderm lineage. As hematopoietic lineages during normal development derive from mesoderm, the finding points to a possible application of DEP formed EBs in the production of blood-based products from ESCs. 相似文献

Teachers’ psychological well‐being is important for teachers and students, but teaching is highly stressful, particularly in special education. We examined the role of experiential avoidance (EA) in the well‐being of 529 middle and elementary school teachers. EA involves the tendency to avoid thoughts, feelings, and other internal experiences, even when doing so causes long‐range consequences. Using a teacher‐specific measure, we investigated EA's relationship to stress associated with student misbehavior and limited social support. We also assessed EA's relationship to burnout and depression, finding EA significantly and moderately correlated with depression and all scales of Maslach's Burnout Inventory. Mediation analyses showed EA mediated the relationship between stress associated with student behavior and measures of well‐being. We found 26.8% of teachers to be mildly, 8.9% moderately, and 2.8% moderately severely or severely depressed. This evidence concurs with studies showing the value of mindfulness‐based interventions and points to the utility of implementing interventions aimed at decreasing EA in teachers. 相似文献

The aim of this research was to explore why workers in health and social services embarked on a Certificate in Community Care Practice and the extent to which they felt knowledge learnt related to their every‐day work practice. The objective was to indicate how useful more academic courses are for health and social care staff, and to find out the kinds of barriers to practicing theory learnt in the classroom students face in their ‘real world’ of work. Data was collected from 25 mature students (over half were between the ages of 41–50 years), 3 of whom were men from a range of professional backgrounds including; support staff working in residential and domiciliary services and informal (unpaid) carers for people with learning disabilities, mental health difficulties as well as older people. Quantitative (an adapted questionnaire) and qualitative (focus group session which was an integral part of classroom learning about research methodology) methods were employed. Data was analysed using SPSS and thematic analysis. Findings indicated that the main motivators for study was to gain a qualification and for personal development. Students reported their increased desire to link theory learnt which they found highly relevant to their everyday practice, but organisational barriers sometimes precluded them from doing so. The paper ends with policy and practice recommendations. 相似文献
