Predictive indicators for adjustment in 4-year-old children whose mothers used amphetamine during pregnancy     

L Billing  M Eriksson  G Steneroth  R Zetterstr?m 《Child abuse & neglect》1988,12(4):503-507

Psychosocial factors that could be used as predictive indicators for adjustment of 4-year-old children whose mothers had used amphetamine during pregnancy were studied by means of simple and multivariate correlation analyses. The following statistically significant correlations were found: Length of maternal alcohol and drug abuse during pregnancy was correlated negatively with the child's adjustment as were numbers of paternal criminal convictions, number of stress factors of the mother, and number of earlier children born to the mother. Paternal criminality was associated with the outcome, regardless of amount of contact between father and child.  相似文献

Positive and Negative Facets of Formal Group Mentoring: Preservice Teacher Perspectives     

Anita Eriksson 《Mentoring & Tutoring: Partnership in Learning》2013,21(3):272-291

The use of mentoring within teacher education has become more common in recent years, however, there still seems to be a lack of research about formal group mentorship models as a pedagogical process. In my study, I presented knowledge about how a formal group mentorship model used during a teacher education program at a Swedish university has affected the student teachers’ professional development. The findings suggest that nearly all the student teachers describe the mentoring group conversations as beneficial as they have contributed to a strengthened socialization, identity and/or teacher role, a possibility to share experiences, hear others perspectives, and get support in the process of linking theoretical educational content and teaching activities. A few students expressed that the mentoring program has not contributed at all to their professional development.  相似文献   

Booktalk Dilemmas: Teachers' organisation of pupils' reading     

Katarina Eriksson 《Scandinavian Journal of Educational Research》2013,57(4):391-408

The syllabus for mother tongue teaching in Sweden states that an essential goal is that pupils, in conversation with others, should be able to express feelings and thoughts evoked by literature. The present paper addresses how schools try to promote pupils' reading, examining authentic school-run booktalk conversations from a discursive approach. The data consists of video-recorded sessions with small groups of pupils in Grades 4-7. A series of booktalk dilemmas were identified. The so-called book clubs studied were aimed at promoting reading for pleasure. Yet, literary practices were, at times, transformed into calculating tasks, vocabulary lessons or reading aloud exercises. Another complication concerned the synchronising of the pupils' reading, which led to extensive negotiations on the part of teacher and pupils.  相似文献   

The Pimp and the Happy Whore: “Doing Gender” in Film Talk in a School Setting     

Katarina Eriksson Barajas 《Scandinavian Journal of Educational Research》2013,57(6):581-596

The present paper concerns the use of film for eliciting discussions of fundamental values in an upper secondary school setting. In this case, Lilya 4‐ever, a feature film about sex trafficking, is used. The present paper contributes some empirical knowledge about how young people are “doing gender” in a natural setting—an educational context—that celebrates equality values. The examples from a group discussion between pupils reveal a balance between performing the school task, discussing the questions on the sheet the teacher provided, and working on their private identities, which here includes social interplay that among teenagers could involve rejecting an academic identity. The analysis concerns how pupils use discourses drawn from a film in that balancing act. The paper explores how discourses on sex are used to gain power in conversation, to challenge male sexuality, and to reject victimization.  相似文献   

Tutor-student interaction in undergraduate chemistry: a case of learning to make relevant distinctions of molecular structures for determining oxidation states of atoms     

Ilana A. Manneh  Carl-Johan Rundgren  Karim M. Hamza  Lars Eriksson 《International Journal of Science Education》2013,35(16):2023-2043

ABSTRACT

In this study, we explore the issues and challenges involved in supporting students’ learning to discern relevant and critical aspects of determining oxidation states of atoms in complex molecules. We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical epistemology analysis (PEA). The results show that the ability to make relevant distinctions between the different parts of a molecule for solving the problem, even with the guidance of the tutor, seemed to be challenging for students. These shifts were connected to both purposes that were specific for solving the problem at hand, and additional purposes for general learning of the subject matter, in this case how to assign oxidation states in molecules. The students sometimes could not follow the additional purposes introduced by the tutor, which made the related distinctions more confusing. Our results indicate that in order to provide adequate support and guidance for students the tutor needs to consider how to sequence, move between, and productively connect the different purposes introduced in a tutor-student interaction. One way of doing that is by first pursuing the purposes for solving the problem and then successively introduce additional, more general purposes for developing students’ learning of the subject matter studied. Further recommendations drawn from this study are discussed as well.  相似文献   

Factorial Validity and Invariance Testing of the Exercise Dependence Scale-Revised in Swedish and Portuguese Exercisers     

Magnus Lindwall  Antonio Palmeira 《Measurement in physical education and exercise science》2013,17(3):166-179

The present study investigated the factorial validity and factorial invariance of the 21-item Exercise Dependence Scale-Revised using 162 Swedish and 269 Portuguese exercisers. In addition, the prevalence of exercise dependence symptoms and links to exercise behavior, gender, and age in the two samples was also studied. Confirmatory factor analyses demonstrated that the hypothesized 7-factor model made a good fit to data in both samples. Multi-sample analyses supported partial measurement invariance across the samples; only factor loadings involving items 3 and 19 were noninvariant. The “Reduction in Other Activities” and “Lack of Control” factors were the most problematic scales in terms of average variance explained and reliability measures of weighted omega and Cronbach's alpha. In total, 9.2% of the Swedish sample and 5.2% of the Portuguese sample were classified as at risk for exercise dependence. Overall, the results support the factorial validity of the translated Exercise Dependence Scale-Revised in samples outside North-America, although more research is needed.  相似文献   

Maximal oxygen uptake versus maximal power output in children     

Magnus Dencker  Ola Thorsson  Magnus K. Karlsson  Christian Lindén  Per Wollmer  L. B. Andersen 《Journal of sports sciences》2013,31(13):1397-1402

Abstract

Maximal oxygen uptake ([Vdot]O_2max) is considered the optimal method to assess aerobic fitness. The measurement of [Vdot]O_2max, however, requires special equipment and training. Maximal exercise testing with determination of maximal power output offers a more simple approach. This study explores the relationship between [Vdot]O_2max and maximal power output in 247 children (139 boys and 108 girls) aged 7.9–11.1 years. Maximal oxygen uptake was measured by indirect calorimetry during a maximal ergometer exercise test with an initial workload of 30 W and 15 W · min^?1 increments. Maximal power output was also measured. A sample (n = 124) was used to calculate reference equations, which were then validated using another sample (n = 123). The linear reference equation for both sexes combined was: [Vdot]O_2max (ml · min^?1) = 96 + 10.6 · maximal power + 3.5 · body mass. Using this reference equation, estimated [Vdot]O_2max per unit of body mass (ml · min^?1 · kg^?1) calculated from maximal power correlated closely with the direct measurement of [Vdot]O_2max (r = 0.91, P <0.001). Bland-Altman analysis gave a mean limits of agreement of 0.2±2.9 (ml · min^?1 · kg^?1) (1 s). Our results suggest that maximal power output serves as a good surrogate measurement for [Vdot]O_2max in population studies of children aged 8–11 years.  相似文献   

The Dynamics of Professional Identity     

Magnus Fredriksson 《Journalism Practice》2014,8(5):585-595

The aim of this article is to analyse how journalists' professional identity is related to their attitude towards PR. The focus is how—and to what extent—journalistic ideology, organizational belonging and the individual's social position influence journalists' perception that other journalists working with PR lower the trustworthiness of journalism. The analyses rest on data from the Swedish Journalist Survey 2011, which is a national representative survey of Swedish journalists. The results show that journalists in general embrace a hostile attitude towards journalists who start working as PR practitioners. However, those who have worked as a journalist for fewer years or have journalistic ideals promoting the amusement function of journalism, or have worked as a freelance, or been employed in an organization producing newsletters, as well as female journalists, weaken this posture. The article concludes with a discussion on how the results could be understood in relation to recent changes in journalism's power and prerequisites, and how a professional identity might function as a form of resistance.  相似文献   

Long-term microfluidic glucose and lactate monitoring in hepatic cell culture     

Sebastian Prill  Magnus S. Jaeger  Claus Duschl 《Biomicrofluidics》2014,8(3)

Monitoring cellular bioenergetic pathways provides the basis for a detailed understanding of the physiological state of a cell culture. Therefore, it is widely used as a tool amongst others in the field of in vitro toxicology. The resulting metabolic information allows for performing in vitro toxicology assays for assessing drug-induced toxicity. In this study, we demonstrate the value of a microsystem for the fully automated detection of drug-induced changes in cellular viability by continuous monitoring of the metabolic activity over several days. To this end, glucose consumption and lactate secretion of a hepatic tumor cell line were continuously measured using microfluidically addressed electrochemical sensors. Adapting enzyme-based electrochemical flat-plate sensors, originally designed for human whole-blood samples, to their use with cell culture medium supersedes the common manual and laborious colorimetric assays and off-line operated external measurement systems. The cells were exposed to different concentrations of the mitochondrial inhibitor rotenone and the cellular response was analyzed by detecting changes in the rates of the glucose and lactate metabolism. Thus, the system provides real-time information on drug-induced liver injury in vitro.  相似文献
