Integration of merged delayed-enhanced magnetic resonance imaging and multidetector computed tomography for the guidance of ventricular tachycardia ablation: a pilot study

BACKGROUND Delayed enhancement (DE) MRI can assess the fibrotic substrate of scar-related VT. MDCT has the advantage of inframillimetric spatial resolution and better 3D reconstructions. We sought to evaluate the feasibility and usefulness of integrating merged MDCT/MRI data in 3D-mapping systems for structure-function assessment and multimodal guidance of VT mapping and ablation. METHODS Nine patients, including 3 ischemic cardiomyopathy (ICM), 3 nonischemic cardiomyopathy (NICM), 2 myocarditis, and 1 redo procedure for idiopathic VT, underwent MRI and MDCT before VT ablation. Merged MRI/MDCT data were integrated in 3D-mapping systems and registered to high-density endocardial and epicardial maps. Low-voltage areas (<1.5 mV) and local abnormal ventricular activities (LAVA) during sinus rhythm were correlated to DE at MRI, and wall-thinning (WT) at MDCT. RESULTS Endocardium and epicardium were mapped with 391 ± 388 and 1098 ± 734 points per map, respectively. Registration of MDCT allowed visualization of coronary arteries during epicardial mapping/ablation. In the idiopathic patient, integration of MRI data identified previously ablated regions. In ICM patients, both DE at MRI and WT at MDCT matched areas of low voltage (overlap 94 ± 6% and 79 ± 5%, respectively). In NICM patients, wall-thinning areas matched areas of low voltage (overlap 63 ± 21%). In patients with myocarditis, subepicardial DE matched areas of epicardial low voltage (overlap 92 ± 12%). A total number of 266 LAVA sites were found in 7/9 patients. All LAVA sites were associated to structural substrate at imaging (90% inside, 100% within 18 mm). CONCLUSION The integration of merged MDCT and DEMRI data is feasible and allows combining substrate assessment with high-spatial resolution to better define structure-function relationship in scar-related VT.

National youth team football players between the conflicting priorities of sports success and vocational training

In view of the risks involved in relying on a professional career in football as a way of making a future living, most players on Swiss National Youth Football Teams pursue some form of vocational training at the same time. This paper investigates the question under what conditions a successful football career is possible when faced with such a dual burden. In order to examine the development process as holistically as possible, a person-oriented approach was chosen. 159 former Swiss National Youth Team players were retrospectively interviewed about their careers, and the data were analysed using the LICUR method (Bergman, Magnusson, & El-Khouri, 2003). This involves identifying certain patterns in the relevant variables of sports career, vocational career and family support, and then comparing these with the performance at the age of peak performance. Through this, it was possible to identify promising patterns of development. It turns out that the critical transition, at the age of about 15–16 years, is characterised overall by stability. The most successful patterns display above-average family support accompanied by above-average professional talent promotion in the clubs. In this constellation, the football players who are later successful pursue vocational training courses leading to low levels of educational qualification.

Gender Stereotypes and Gendered Vocational Aspirations among Secondary School Students

Research Topic/Aim: Horizontal gender inequalities appear to be rather stable, with girls more often choosing ‘female' service professions, and boys choosing career paths related to science, technology, engineering or mathematics, since measures to bring more women into typical ‘male' jobs and more men into typical ‘female' jobs did not turn out to be sustainable. This paper focuses on gender stereotypes, namely non-egalitarian patriarchal gender-role orientations and gender associations of the school subjects German and mathematics. Dealing with and abolishing such gender stereotypes may be key strategy to reach sustainability regarding more equal vocational choices. Thus, gender stereotypes will be theorised and empirically analysed as a major predictor of gender-typical vocational perspectives considering interest in these school subjects as a mediating factor. Furthermore, we focus on structural patriarchy as a root of gender-role orientations, and teacher gender regarding its impact on gendered images of subjects. Theoretical and methodology framework: Our analyses of gender segregation in vocational aspirations and vocational choice center on Gottfredson's (2002; Gottfredson and Becker, 1981) Theory of Circumscription, Compromise and Self-Creation. One of the main assumptions of this theory is that people associate jobs with particular sexes and those jobs that do not fit particular gender roles are not considered. Empirical analyses are based on survey data of eighth-graders in the Swiss canton of Bern (N = 672). Structural Equation Models (SEM) for male and female students are estimated. Conclusions/Findings: Results reveal different patterns for boys and girls; for boys, gender-typical (male) vocational perspective could be explained via gender role orientations, interest in mathematics and gender associations of the school subjects, for girls, the factors under consideration could be empirically linked to ‘atypical vocational perspective'. Relevance to Nordic educational research: The study focuses on gender relations in society and how they are reproduced. Gender segregation in vocational choice and at the labour market is a universal issue - affecting both egalitarian and non-egalitarian gender regimes in similar ways. Although in general Northern countries appear to be more equal regarding gender inequality, gender segregation is rather persistent (Jarman, Blackburn and Brooks, 2012) and therefore remains a relevant topic.

Vocational identity achievement as a mediator of presence of calling and life satisfaction

The present study explores what mechanism might be responsible for the reported link between presence of a calling in one’s career and life satisfaction. It is proposed that vocational identity achievement acts as one important mediator of this relation and that the effects can be observed even when controlling for core self-evaluations (CSEs). The study used a short-term longitudinal design based on a sample of 269 German college students from different majors. The results confirmed the mediation model, with calling predicting vocational identity achievement 6 months later and identity serving as a stronger predictor of life satisfaction, all controlling for CSEs. However, contrary to previous research, presence of calling was not directly related to life satisfaction and even showed a negative relation when vocational identity achievement was controlled. The results are interpreted to suggest a multifaceted relation between calling and life satisfaction.

Vocational identity trajectories: Differences in personality and development of well-being

This person-centred study investigated the longitudinal patterns of vocational identity development in relation to personality, the development of well-being, gender, nationality and the attended school track among two cohorts of Swiss adolescents in 8th or 9th grade (N = 269) and in 11th or 12th grade (N = 230). The results confirmed the existence of four identity statuses, namely, achievement, foreclosure, moratorium and diffusion. Forty-two per cent of students showed progressive patterns of identity development, while 37% remained in their identity status over time. Students with different statuses and status change patterns differed significantly in their personality traits. Higher neuroticism related to the emergence of identity exploration over time, while conscientiousness related to maintaining or achieving a sense of identity commitment in terms of achievement or foreclosure. Controlling for the effects of socio-demographics and personality traits, students who reached or maintained a state characterized by identity clarity and commitment showed a relative increase in life satisfaction, while those entering a state of identity crisis or exploration showed a decrease in life satisfaction.

Vocational indentity as a mediator of the relationship between core self-evaluations and life and job satisfaction

This study investigated whether vocational identity achievement mediates the relation between basic personality dispositions (i.e. core self-evaluations) and career and well-being outcomes in terms of job and life satisfaction. Two studies with Swiss adolescents were conducted. Study 1 (N= 310) investigated students in eighth grade, prior to making the transition to vocational education and training (VET); it showed that vocational identity related positively to life satisfaction but that this relationship disappeared once core self-evaluations were controlled. Study 2 (N= 150) investigated students in their second year of VET; it showed that job satisfaction was unrelated to identity and self-evaluations. However, identity fully mediated the relation between self-evaluations and life satisfaction.

Relation of vocational identity statuses to interest structure among Swiss adolescents

Vocational identity is one core component of identity construction in adolescence. The current study investigated whether vocational interest structure in terms of differentiation, coherence, elevation, and interest-aspiration congruence would differentiate among students in vocational identity achievement, foreclosure, moratorium, and diffusion. Swiss students at the beginning of eighth grade (N = 341) participated in the study. Groups were created using cluster analysis based on the dimensions of career exploration and career commitment, and group differences were explored with discriminant analysis. Controlling for sociodemographic variables, higher interest differentiation and elevation distinguished students in achievement/moratorium from those in diffusion. More interest elevation differentiated moratorium from foreclosure. (Contains 1 figure and 3 tables.)

Effects of orientations to happiness on vocational identity achievement

There is an increased interest in vocational psychology and career counseling regarding the link between career development and well-being, yet, little is known about how different ways to achieve well-being or happiness relate to career development. This study explored the relationship between 3 orientations to happiness (meaning, pleasure, and engagement) and vocational identity achievement among 2 groups of Swiss adolescents (n = 268, 8th grade; n = 208, 11th grade). The results indicated that more orientation to meaning and engagement but not to pleasure positively related to vocational identity achievement.

Vocational Interests and Career Goals: Development and Relations to Personality and Middle Adolescence

Cross-sectional research implies a close relation of vocation interests, goals, and traits, yet little is known about their reciprocal development over time. This longitudinal study examined development of Things/People (T/P) and Data/Ideas (D/I) vocational interests and career goals in relation to Big Five personality traits among 292 Swiss adolescents with a cross-lagged panel design with two measurement points over 1 year from seventh to eighth grade. Interests and goals were significantly related within time and showed significant interactions across time. Traits related significantly and equally to interests and goals within time and predicted their development across time except for T/P goals. Goals and interests possessed incremental validity above traits in affecting each other. Implications include the need to account for dynamic processes in the development of goals and interests and their systematic relation to traits in theory and practice.

Development and Criterion Validity of Differentiated and Elevated Vocational Interests in Adolescence

Interest differentiation and elevation are supposed to provide important information about a person’s state of interest development, yet little is known about their development and criterion validity. The present study explored these constructs among a group of Swiss adolescents. Study 1 applied a cross-sectional design with 210 students in 11th grade. Study 2 applied a 1-year longitudinal design with 289 students in 7th to 8th grade. gender, personality traits, and career exploration were significant predictors of state and development of differentiation and elevation. Increase in differentiation predicted increase in career decidedness above traits. elevation could not predict increase in exploration behavior over traits. The results provide support for differentiation and elevation as important aspects of adolescents’ vocational interests.
