To determine the concentration of ionized calcium (iCa) collected in lithium heparin and gel tubes and to correlate the measured iCa with calculated iCa. Anaerobic fasting blood samples were simultaneously collected from healthy laboratory workers in lithium-heparin and gel tubes. iCa, pH, total calcium (CaT), total protein and albumin were measured. Ionized Ca was calculated with albumin and globulin values using an appropriate formula. Mean iCa in gel tubes showed a positive constant bias of 0.08 mmol/L (p < 0.001) when compared to lithium heparin results. The mean pH of blood taken in lithium heparin and gel tubes was non-significant (p = 0.3). Measured iCa poorly correlated with CaT (r = 0.2, p = 0.1) and calculated iCa (r = 0.2, p = 0.2). To evaluate the calcium status direct measurement of iCa must be done rather than using the formulae for iCa determination. In addition serum is recommended as the choice of sample for iCa determination in comparison to plasma samples. 相似文献

ABSTRACTDo the narratives of employability constructed by higher education institutions for marketing purposes differ from the conceptualisation and/or the realisation of employability within those institutions? The study reported here drew on interviews with 16 senior academic and student support staff who were tasked with developing student employability at one of nine institutions in Australia, Canada and the UK. We employed Holmes’ conceptions of employability as possessional, positional or processual to analyse how the interviewees conceptualised employability and the presentation of employability on the institutional websites. We found that most institutions’ employability marketing narratives were inconsistent with the institutional practice reported by staff. We explain this tension in the context of two competing characterisations of higher education: a university-student transaction view; and a learning view. We emphasise the need for internal and external narratives to align and advocate the need for engagement in a constructive and critical dialogue involving all stakeholders. 相似文献

In this article we describe the effectiveness of a programme-wide communication skills training framework incorporated within a one-year biological sciences taught Masters course designed to enhance the competency of students in communicating scientific research principally to a scientific audience. In one class we analysed the numerical marks achieved by students (N 61) for specific communication assignments completed at the start and at the end of the course. This was complemented by questionnaires administered to students at the beginning and at the end of the course to self-assess their competency and to elicit their views on the usefulness of the training received. We considered three questions: did students’ communication skills improve during the course; did the outcomes depend on the place of previous education (UK or non-UK); and how useful did students consider the learning and teaching activities to be? We show that the training improved students’ self-reported competency in most of the communication skills considered. Coursework marks for writing literature reviews improved during the course (p < 0.001). Those marks were marginally associated (that is, approaching statistical significance after Bonferroni correction) with the place of previous education (relatively high in UK students; p = 0.005). Coursework marks for writing research proposals did not change during the course (p = 0.361) but did depend on place of previous education (relatively high for UK students (p = 0.001). Although this small study’s intriguing results merit further investigation, our initial data supports the use of a programme-wide framework of the type presented here to facilitate communications skills development amongst biological science graduate students. 相似文献

The current study uses a grounded theory approach to explore dimensions and bi-national comparisons of active information seeking efforts (seeking) for and passive information acquisition (scanning) of drug-related information among two college student samples from the United States (N = 25) and Israel (N = 39). Specifically, the study focuses on seeking and scanning related to amphetamines and marijuana, two frequently used drugs among college populations, about which information is easily accessible. Results of semi-structured interviews suggest that information scanning and seeking about marijuana and amphetamines are common, particularly from peers and from the Internet. The analysis uncovers themes relating to young adults’ drug-related, information-seeking behaviors, including cross-source information acquisition across interpersonal and media sources, and motivations for engaging in active efforts to seek drug-related information. These findings extend research on information seeking and scanning and suggest future research should examine predictors and effects of these behaviors in the context of substance use. 相似文献
