Elimination of lipaemic interference by high-speed centrifugation

IntroductionIn order to deliver high quality results, detection and elimination of possible analytical interferences, such as lipaemia, is crucial. The aim of this study is to evaluate the efficacy of high-speed centrifugation in eliminating lipaemic interference and to define own lipaemic index (LI) for the studied biochemical analytes.Materials and methodsEvaluated analytes were: albumin, alkaline phosphatase, alanine-aminotransferase (ALT), aspartate-aminotransferase (AST), calcium, creatinine, gamma-glutamyltransferase (GGT), glucose, phosphates, total proteins, urea and total bilirubin. Those analytes and LIs have been analysed in duplicate in the Roche Diagnostics-c8000 analyser in samples centrifuged at 3000 rpm/10 minutes in the SL16 (Thermo Scientific, Waltham, USA) centrifuge and according to an own high-speed centrifugation protocol (12,900 rpm/15 minutes) in the MicroCL17R (Thermo Scientific, Waltham, USA) centrifuge. Lipaemia has been measured in each sample. The efficiency of high-speed centrifugation is verified by the Wilcoxon test (P < 0.05). In cases where significant differences are observed, our own LI is calculated. For ALT and AST, it is verified by McNemar test (P < 0.05). For creatinine, both Wilcoxon and McNemar test were applied.ResultsThere were statistically significant differences in analyte concentration before and after high-speed centrifugation for: albumin, creatinine, GGT, glucose, phosphates, urea and total bilirrubin. Own LI is calculated. McNemar test shows statistically significant diferences in the proportion of delivered results before and after high-speed centrifugation in ALT, AST and creatinine.ConclusionsThis study confirms the efficacy of high-speed centrifugation protocol for all the considered analytes, excepting calcium, alkaline phosphatase and total proteins.     

TASK ANALYSIS: BULIDING MODELS OF CHANGE PROCESSES IN GIFTED EDUCATION

Researchers in the field of gifted education are becoming increasingly aware that a variety of research approaches can make contributions to research on giftedness. This paper describes task analysis, a research methodology derived from counseling process research. Task analysis appears to be a useful research approach for building theoretical models of how therapeutic and educational interventions can facilitate positive changes in gifted children. The paper traces the historical development of task analysis methodology, describes the steps involved in conducting a rational‐empirical task analysis of change processes, and provides an example of how task analysis methodology might be applied to investigations of change processes in the field of gifted education.     

TEACHING GERONTOLOGY VIA DISTANCE EDUCATION: VARIETY IS THE KEY TO SUCCESS

Teaching gerontology via distance education is growing in popularity. Yet, many challenges are encountered by those teaching gerontology at a distance; some technological and others pedagogical in nature. Successful strategies for structuring and teaching televised gerontology courses are presented in this paper. Strategies focus on types of teacher preparation, use of pedagogical tools, development and maintenance of rapport with students at remote sites, and ways to improve teaching of distance education classes in gerontology. It is argued that workload and compensation for instructors teaching distance education need to be addressed by administration in order to develop high quality distance education programs.     

Do labels matter? Analysis of teachers' self-efficacy towards the autism spectrum disorder depending on the diagnostic label used (ASD or Asperger's)

Changes in the classification of autism and Asperger's syndrome led to changes in social perception of ASD. Since last criteria, studies indicate higher levels of stigma towards ASD than towards Asperger's. These prejudices are barriers to inclusive education. Thus, it is relevant (1) to evaluate pre-service teachers' self-efficacy towards the label of ASD; (2) to evaluate pre-service teachers' self-efficacy towards the label of Asperger's and (3) to compare those results to analyse whether the use of different diagnostic labels brings about different levels of self-efficacy. One hundred and eighty-six primary education pre-service teachers participated in the current study. Two adaptations of the Autism Self-Efficacy Scale for Teachers (ASSET) were used: a version with the label of ‘ASD’ (n = 96) and another for ‘Asperger's’ (n = 90). The scores obtained by the group asked about ASD were high according to the ASSET score range, while the scores obtained by the group asked about Asperger's were medium. After comparing the results, participants asked about the label ASD showed higher levels of self-efficacy than participants asked about Asperger's. These results could be a consequence of the consolidation of the ASD diagnosis among society and the higher presence of children with ASD in schools and cultural products, among other factors.     

Can self-esteem protect against the deleterious consequences of self-objectification for mood and body satisfaction in physically active female university students?

Using objectification theory (Fredrickson & Roberts, 1997), this study tested the interaction between self-objectification, appearance evaluation, and self-esteem in predicting body satisfaction and mood states. Participants (N = 93) were physically active female university students. State self-objectification was manipulated by participants wearing tight revealing exercise attire (experimental condition) or baggy exercise clothes (control condition). Significant interactions emerged predicting depression, anger, fatness, and satisfaction with body shape and size. For participants in the self-objectification condition who had low (as opposed to high) appearance evaluation, low self-esteem was associated with high depression, anger, and fatness and low satisfaction with body shape and size. In contrast, for participants with high self-esteem, these mood and body satisfaction states were more favorable irrespective of their levels of appearance evaluation. For female exercisers, self-esteem-enhancing strategies may protect against some of the negative outcomes of self-objectification.     

Exploring Dialectical Tensions of Leading Volunteers in Two Community Choirs

Leaders of volunteers face different challenges than leaders of paid employees due to different motivations and reward expectations. After synthesizing previous research applying dialectical theory to group members or leaders, this study examines the dialectical tensions that leaders of volunteers experienced and the communication they used to manage those tensions as reported by both the leaders and the volunteers. A constant-comparison method was used to analyze observations and interviews of members and leaders of two community choirs. The findings suggest that leaders of volunteers face eight dialectical tensions representing three broad categories: (a) task and relationship; (b) process and outcome; and (c) internal and external. Leaders negotiated these dialectical tensions through communication strategies including use of humor and appeals to artistic spirituality. These strategies represent hybridization and dualistic discourse rather than a monologic emphasis of one course of action over another.     

Talk about texts: reading as a social event

Drawing on anthropological evidence that interactions with texts are often mediated through oral language practices and Vygotsky's ideas about the primacy of social dialogue for individual intellectual development, the authors argue that children's informal talk about both electronic and printed texts throws new light on the reading process as a whole. They analyse children's talk about a school library book, a piece of graffiti, a television programme and a film to show how readings are shaped by the social organization and personal relationships of the readers, whether in curriculum activities, friendship groups or at home in the family. Readings are constructed, contested and negotiated through talk at the point where texts are first calculated and reshaped again when they are jointly recalled. Talk also helps to construct the text's legitimate audience and the reader's position within it.     

Containment and denial: raising awareness of unconscious processes present when teachers are working with children and families where there is domestic abuse

This paper reports a small-scale, mixed methods research project exploring the perceptions and experiences of primary school teachers regarding domestic abuse. The paper focuses on the psychoanalytic concepts of containment and denial present in such situations. Questionnaire findings suggested that there was a significant difference between teachers who had attended relevant training and those who had not in their confidence levels in 1) responding to disclosures, and 2) recognising whether a child was exposed to domestic abuse (n = 165). Semi-structured interviews, analysed using thematic analysis, were carried out with experienced teachers (n = 8). Four overarching themes were identified: emotional factors of the teacher’s role; working within the school system; the relationship with the child and family; and uncertainty about what teachers need to know. Findings are discussed in relation to the psychoanalytic concepts of containment and denial. Implications for practice, identifying the roles of unconscious processes and holistic containment, are discussed.     

Proposals for improving the transition process of young people with intellectual disabilities in Spain: insights from focus groups of professionals,young people and their families

This research aims to present proposals that can improve the transition to adulthood of young people with intellectual disabilities (ID). Four focus groups were set up in three different cities in Spain, each comprising education and social work professionals, people with ID and family members. In total, 32 participants were included in the study. The discussions were recorded, transcribed and analysed using thematic content analysis. Improvements proposed by participants were organised into six themes: coordination between services and professionals; curricular approaches; participation by young people with ID; peer-relationship networks; family and administration. Participants highlighted the need to make the curriculum more flexible and foster curricular experiences related to social and workplace inclusion, as well as establish more continuity in guidance processes throughout the different stages of education and especially at the end of secondary education. Participants also suggested the need for young people with ID to have a more prominent role in their educational process, and strengthening their social networks by promoting their participation in community activities.
