INTRODUCTION An accurate description of the biomechanical behavior of the spine is crucial for the planning of scoliotic surgical correction as well as for the understanding of degenerative spine disorders. The current clinical assessments of spinal mechanics such as side-bending or fulcrum-bending tests rely on the displacement of the spine observed during motion of the patient. Since these tests focused solely on the spinal kinematics without considering mechanical loads, no quantification of the mechanical flexibility of the spine can be provided. METHODS A spinal suspension test (SST) has been developed to simultaneously monitor the force applied on the spine and the induced vertebral displacements. The system relies on cervical elevation of the patient and orthogonal radiographic images are used to measure the position of the vertebras. The system has been used to quantify the spinal flexibility on five AIS patients. RESULTS Based on the SST, the overall spinal flexibility varied between 0.3 °/Nm for the patient with the stiffer curve and 2 °/Nm for the less rigid curve. A linear correlation was observed between the overall spinal flexibility and the change in Cobb angle. In addition, the segmental flexibility calculated for five segments around the apex was 0.13 ± 0.07 °/Nm, which is similar to intra-operative stiffness measurements previously published. CONCLUSIONS In summary, the SST seems suitable to provide pre-operative information on the complex functional behavior and stiffness of spinal segments under physiological loading conditions. Such tools will become increasingly important in the future due to the ever-increasing complexity of the surgical instrumentation and procedures.

Vieles ist Psychologie, auch im Recht. Denn rechtliche Beziehungen entfalten sich stets zwischen Menschen; ihr Gelingen hängt daher massgeblich von psychologischen Faktoren ab. Juristinnen und Juristen haben folglich allen Grund, sich für Psychologie zu interessieren. Das Schrifttum lässt sie dabei jedoch weitgehend im Stich. Das vorliegende Buch will nun am Beispiel des öffentlichen Verfahrensrechts die juristische Relevanz psychologischer Fragestellungen verdeutlichen und damit zum interdisziplinären Arbeiten anregen. Die Psychologie bietet nämlich interessante Lösungsansätze für viele drängende Fragen: Wie kann eine möglichst hohe Akzeptanz staatlicher Entscheide erreicht werden? Ist Unbefangenheit in der Rechtsfindung und Rechtsprechung überhaupt möglich? Welchen Kriterien muss eine höfliche Verfahrenskommunikation genügen?

This longitudinal panel study investigated predictors and outcomes of active engagement in career preparation among 349 Swiss adolescents from the beginning to the end of eighth grade. Latent variable structural equation modeling was applied. The results showed that engagement in terms of self- and environmental-exploration and active career planning related positively to interindividual increases in career decidedness and choice congruence. More perceived social support, early goal decidedness, and particular personality traits predicted more engagement. Support and personality impacted outcomes only mediated through engagement. Early decidedness and congruence were significant predictors of their respective later levels. Implications for practice are presented.

The New Cockney provides a sociolinguistic account of speech variation among adolescents in the 'traditional' East End of London. The study takes account of the social and economic upheaval in the area since the 1950s, primarily concentrating on factors such as the immigration of the Bangladeshi community and its effect on the Cockney dialect. By paying attention to the particular, this book contributes to a better understanding of the more general concerns of linguistic variation. With a focus on the interaction and social practices of a group of adolescents attending a youth centre, the study highlights some of the possible mechanisms for language change.

This longitudinal study of 268 Swiss adolescents, spanning across 8th grade, investigated the relation of intrinsic and extrinsic work values to positive career development in deciding, planning, and exploring. Results showed that girls reported more intrinsic and fewer extrinsic work values compared with boys. Students with an immigration background reported more extrinsic values than did students of Swiss nationality. When gender, nationality, and scholastic achievement were controlled, more general work value endorsement was a significant predictor of an above-average increase in career development over the course of the school year. Endorsement of more intrinsic but not extrinsic work values was related to positive career development.

Being hopeful is critical for individuals who are engaged in vocational pursuits. However, the empirical research examining how and why hope is related to work and career outcomes remains sparse. We evaluate a model that proposes that dispositional hope affects job performance and turnover intentions through increased work motivation in terms of autonomous goals (reason to motivation), positive affective experience at work (energized to motivation), and occupational self-efficacy beliefs (can do motivation). The hypotheses were tested among 590 Swiss adolescents in vocational education and training using path analysis and multiple mediation analyses. The results revealed that hope was positively related to all three motivational states and supervisor-rated job performance and negatively related to turnover intentions. Positive affect mediated the effects of hope on turnover intentions and performance. Autonomous goals mediated the effects of hope on turnover intentions. These results support the importance of hope to employee well-being and organizational outcomes.

Die Studie untersucht, inwiefern der Erfolg im Masterstudiengang Psychologie durch die Durchschnittsnoten der Hochschulzugangsberechtigung (HZB) und die Leistungen im vorangegangenen Bachelorstudiengang vorhergesagt werden kann. Die HZB-Durchschnittsnote erwies sich als ein valider Prädiktor für die Bachelor- und Masterabschlussnote. Die Bachelorabschlussnote sagte die Masterabschlussnote vorher, und diese Vorhersage wurde durch zwei Bacheloreinzelfachnoten noch verbessert. Diese Verbesserung der Vorhersage durch Bacheloreinzelfachnoten hielt jedoch einer näheren statistischen Überprüfung nicht stand. Über die Bachelorabschlussnote hinaus verbesserte die HZB-Durchschnittsnote die Vorhersage der Masterabschlussnote nicht. Die Ergebnisse werden vor dem Hintergrund praktischer Anwendungsfelder wie Studierendenberatung und Studierendenselektion diskutiert.
