Transfer of learning in Swedish technical vocational education: student experiences in the energy and industry programmes

One of the most important issues in vocational education is the interaction between learning at school and at different workplaces. Students need to transfer what they have learned in and between these different learning arenas. However, little agreement exists among researchers on how to conceptualise and empirically study transfer of learning. This article aims to enhance our understanding of this process in technical vocational education by adding a new perspective on transfer: the phenomenological lifeworld approach. Eleven interviews with students enrolled in the Energy and Industry programmes at a Swedish upper-secondary school were conducted. Three transfer themes emerged from the data: learning for new situations, variation and integration of theory and practice. The student perspective, based on the lifeworld approach shows that the different learning arenas – the school and workplaces – can complement each other. The learning arenas offer different opportunities for learning, and learning in both arenas is necessary in order to prepare for an unknown future, according to the students in this study.     

Never riding the tide Seymour Benzer — The founder of neurogenetics

Seymour Benzer pioneered the use of the fruitfly Drosophila melanogaster as a model system for the study of nervous system function and development. His research spanned a range of topics from identification of mutations resulting in temperature-induced paralysis to neurodegenerative diseases and circadian rhythm. Benzer’s indomitable style as a scientist is well worth emulating; his work was driven by his curiosity rather than public pressure or fashion trends.     

Restoring executive confidence in performance improvement

Many organizations have significantly decreased their investment in performance improvement initiatives because they believe they are too risky. In fact, organizations should invest in performance improvements to build cash reserves and gain market share. Recent scientific breakthroughs have led to the development of methodologies and technologies that enable organizations to predictably, quickly, and completely improve performance at low risk and cost. This article presents these new approaches.     

Activity-related typologies and longitudinal change in physical activity and sedentary time in children and adolescents: The UP&DOWN Study

BackgroundChildren and adolescents can be distinguished by different typologies (clusters) of physical activity and sedentary behavior. How physical activity and sedentary behaviors change over time within different typologies is not known. This study examined longitudinal changes in physical activity and sedentary time among children and adolescents with different baseline typologies of activity-related behavior.MethodsIn this longitudinal study (3 annual time points) of children (n = 600, age = 9.2 ± 0.4 years (mean ± SD), 50.3% girls) and adolescents (n = 1037, age = 13.6 ± 1.7 years, 48.4% girls), participants were recruited in Spain in 2011–2012. Latent class analyses identified typologies based on self-reported screen, educational, social and relaxing sedentary behaviors, active travel, muscle strengthening activity, and sport at baseline. Within each typology, linear mixed growth models explored longitudinal changes in accelerometer-derived moderate-to-vigorous physical activity and sedentary time, as well as time by class interactions.ResultsThree typologies were identified among children (“social screenies”, 12.8%; “exercisers”, 61.5%; and “non-sporty active commuters”, 25.7%) and among adolescents (“active screenies”, 43.5%; “active academics”, 35.0%; and “non-sporty active commuters”, 21.5%) at baseline. Sedentary time increased within each typology among children and adolescents, with no significant differences between typologies. No changes in physical activity were found in any typology among children. In adolescents, physical activity declined within all typologies, with “non-sporty active commuters” declining significantly more than “active screenies” over 3 years.ConclusionThese results support the need for intervention to promote physical activity and prevent increases in sedentary time during childhood and adolescence. Adolescents characterized as “non-sporty active commuters” may require specific interventions to maintain their physical activity over time.     

Preparing Site Supervisors of Counselor Education Students

Counselor educators maintain a responsibility for providing site supervisors with professional development opportunities (Council for Accreditation of Counseling and Related Educational Programs. 2009 ). The goal of this study was to evaluate a model for providing preparation to site supervisors. Significant differences were observed from pretest to posttest on the Supervisory Self‐Efficacy Scale (Johnson & Stewart, 2008 ).     

Supporting Australian Torres Strait Islander and Aboriginal nursing students using mentoring circles: an action research study

Attempts to recruit Aboriginal and Torres Strait Islander students into nursing degrees have made minimal impact on the number of registered nurses working in Australia's healthcare sector. Yet increasing the number of Indigenous nurses remains one of the most important objectives in strategies to close the health gap between Indigenous and non-Indigenous people. Poor retention of Aboriginal and Torres Strait Islander students in a Bachelor of Nursing Science degree offered in far north Queensland, Australia, indicates the need for a different approach to support and retain Indigenous students. This action research study used a decolonizing methodology and was conducted at a satellite university campus in a remote Torres Strait Island community. Researchers trialled the use of a mentoring circle to support and retain nursing students and interviewed mentors and mentees about their experiences. Grounded theory methods were used to analyse the data. Findings indicated a growth in participant students’ emotional intelligence as a result of participating in a mentoring circle. Students developed confidence, formed a group identity, better-negotiated the university environment, became more effective communicators and supported one another through difficulties. The mentoring circle model improved students' university experience and its use should be considered by tertiary educators working with Indigenous students.     

Microfluidic impedance cytometry of tumour cells in blood

The dielectric properties of tumour cells are known to differ from normal blood cells, and this difference can be exploited for label-free separation of cells. Conventional measurement techniques are slow and cannot identify rare circulating tumour cells (CTCs) in a realistic timeframe. We use high throughput single cell microfluidic impedance cytometry to measure the dielectric properties of the MCF7 tumour cell line (representative of CTCs), both as pure populations and mixed with whole blood. The data show that the MCF7 cells have a large membrane capacitance and size, enabling clear discrimination from all other leukocytes. Impedance analysis is used to follow changes in cell viability when cells are kept in suspension, a process which can be understood from modelling time-dependent changes in the dielectric properties (predominantly membrane conductivity) of the cells. Impedance cytometry is used to enumerate low numbers of MCF7 cells spiked into whole blood. Chemical lysis is commonly used to remove the abundant erythrocytes, and it is shown that this process does not alter the MCF7 cell count or change their dielectric properties. Combining impedance cytometry with magnetic bead based antibody enrichment enables MCF7 cells to be detected down to 100 MCF7 cells in 1 ml whole blood, a log 3.5 enrichment and a mean recovery of 92%. Microfluidic impedance cytometry could be easily integrated within complex cell separation systems for identification and enumeration of specific cell types, providing a fast in-line single cell characterisation method.
