Adaption of cardio-respiratory balance during day-rest compared to deep sleep—An indicator for quality of life?

Heart rate and breathing rate fluctuations represent interacting physiological oscillations. These interactions are commonly studied using respiratory sinus arrhythmia (RSA) of heart rate variability (HRV) or analyzing cardiorespiratory synchronization. Earlier work has focused on a third type of relationship, the temporal ratio of respiration rate and heart rate (HRR). Each method seems to reveal a specific aspect of cardiorespiratory interaction and may be suitable for assessing states of arousal and relaxation of the organism. We used HRR in a study with 87 healthy subjects to determine the ability to relax during 5 day-resting periods in comparison to deep sleep relaxation. The degree to which a person during waking state could relax was compared to somatic complaints, health-related quality of life, anxiety and depression. Our results show, that HRR is barely connected to balance (LF/HF) in HRV, but significantly correlates to the perception of general health and mental well-being as well as to depression. If relaxation, as expressed in HRR, during day-resting is near to deep sleep relaxation, the subjects felt healthier, indicated better mental well-being and less depressive moods.

Longitudinal Measurement Invariance Issues Illustrated by Examples of Marital Satisfaction in Later Life and the Structure of Psychopathology Before and After Psychotherapy

Talk at the Symposium "Opportunities and Challenges of Longitudinal Perspectives"

Trajectories of psychological adaptation to marital breakup after a long-term marriage

While the negative effects of divorce on well-being are well documented in research literature, the large individual differences in psychological adaptation over time are still not well understood. This is especially the case for marital breakup after long-term marriage, which is still a neglected research topic. Against this background, the aim of the present contribution is to shed light on the various trajectories of psychological adaptation to marital breakup after a long-term relationship. Data stem from a longitudinal survey study, which is part of the Swiss National Centre of Competence in Research ‘LIVES – Overcoming vulnerability: life course perspectives’ (funded by the Swiss National Science Foundation). Our analyses are based on results of an exploratory latent profile analysis performed at the first assessment in 2012 among 308 divorced participants aged 45 – 65 years, who divorced after an average of 25 years of marriage (Perrig-Chiello, Hutchison, & Morselli, 2014). Five different groups regarding psychological adaptation to marital breakup (i.e. life satisfaction, depression, hopelessness, subjective health, and mourning) were identified. They were composed of two larger groups of individuals that adapted quite well or very well (“average copers”, n=151 and “resilients”, n=90) and of three smaller groups with major difficulties to adjust to the new situation (“vulnerables”, n= 18; “malcontens”, n= 37 and “resigned ones”, n=12). Clusters differed statistically significant regarding personality variables, time since separation, current relationship status, and financial situation. In the present contribution, we want to investigate the course of adaptation of the five classes two years later by using latent transition analysis. Furthermore, we aim to examine which variables in terms of personality, relationship status, variables of the context of the separation and socio-demographic variables are crucial for change or stability in levels of adaptation in the different classes. The evaluation of the trajectories of adaptation to this critical life event and the identification of variables that enhance the adaptation over time is essential for developing more differentiated measures in counselling as well as intervention techniques in clinical and social services.

Gender Segregation in Vocational Education: Introduction

This introductory chapter develops the overall research focus and the aim of the present special issue ‘Gender segregation in vocational education’. Against the backdrop of strong horizontal gender segregation in vocational education and training (VET), we ask how institutional arrangements affect gendered (self-)selection into VET, and to what extent the patterns of the latter vary by context and over time. In order to expand our knowledge about the impact of educational offers and policies on gendered educational pathways and gender segregation in the labour market, we have gathered comparative quantitative studies that analyse the relationship between national variations in the organization of VET and cross-national differences in educational and occupational gender segregation from an institutional perspective. Following a review of the core literature within the field of gender segregation in VET, this introduction presents a discussion of education system classifications and institutional level mechanisms based on the contributions made in this volume. We then discuss gendered educational choices at the individual level, with particular emphasis on variation across the life course. Finally, we conclude our introductory chapter by commenting on the main contributions of the volume as a whole, as well as addressing suggestions for further research.

Remission in schizophrenia: validity, frequency, predictors, and patients' perspective 5 years later

In March 2005, the Remission in Schizophrenia Working Group (RSWG) proposed a consensus definition of symptomatic remission in schizophrenia and developed specific operational criteria for its assessment. They pointed out, however, that the validity and the relationship to other outcome dimensions required further examination. This article reviews studies on the validity, frequency, and predictors of symptomatic remission in schizophrenia and studies on patients' perspectives. These studies have demonstrated that the RSWG remission criteria appear achievable and sustainable for a significant proportion of patients, and are related to a better overall symptomatic status and functional outcome and, to a less clear extent, to a better quality of life and cognitive performance. However, achieving symptomatic remission is not automatically concurrent with an adequate status in other outcome dimensions. The results of the present review suggest that the RSWG remission criteria are valid and useful. As such, they should be consistently applied in clinical trials. However the lack of consensus definitions of functional remission and adequate quality of life hampers research on their predictive validity on these outcome dimensions. Future research should therefore search for criteria of these dimensions and test whether the RSWG remission criteria consistently predict a "good" outcome with respect to functioning and quality of life.

Health care for older persons in Switzerland: a country profile

Switzerland has the second-most-expensive healthcare system worldwide, with 11.5% of gross domestic product spent on health care in 2003. Switzerland has a healthcare system with universal insurance coverage and a social insurance system, ensuring an adequate financial situation for 96% of the 1.1 million older inhabitants. Key concerns related to the care of older persons are topics such as increasing healthcare costs, growing public awareness of patient autonomy, and challenges related to assisted suicide. In 2004, the Swiss Academy of Medical Sciences issued guidelines for the care of disabled older persons. Since 2000, geriatrics has been a board-certified discipline with a 3-year training program in addition to 5 years of training in internal or family medicine. There are approximately 125 certified geriatricians in Switzerland, working primarily in geriatric centers in urban areas. Switzerland has an excellent research environment, ranking second of all countries worldwide in life sciences research-but only 13th in aging research. This is in part due to a lack of specific training programs promoting research on aging and inadequate funding. In addition, there is a shortage of academic geriatricians in Switzerland, in part due to the fact that two of five Swiss universities had no academic geriatric departments in 2005. With more-adequate financial resources for academic geriatrics, Switzerland would have the opportunity to contribute more to aging research internationally and to improved care for older patients.

Intergenerationale Mobilität im Lebensverlauf oder: Ist der öffentliche Dienst ein Mobilitätskanal zwischen Generationen?

Aus der Lebensverlaufsperspektive wird die intergenerationale Mobilität von Männern und Frauen in den Kohorten 1929-31, 1939-41 und 1949-51 untersucht. In welchem Umfang hat die Expansion des öffentlichen Dienstes Mobilitätschancen eröffnet? Inwieweit hat der öffentliche Dienst als Sonderstruktur im Gegensatz zur Privatwirtschaft seine Funktion als "Mobilitätskanal" ausgeweitet? Modifizieren für den öffentlichen Dienst charakteristische institutionelle Regelungen der Rekrutierung und Allokation von Arbeitskräften diese Funktion? Für empirische Analysen wurden Längsschnittdaten des Lebensverlaufsprojekts am Berliner Max-Planck-Institut für Bildungsforschung herangezogen. Zunehmende herkunftsbedingte und bildungsmäßige Ungleichheit bestimmen einen Großteil der Chancen intergenerationaler Mobilität. Die Ausdehnung der Staatsbeschäftigung hat dazu geführt, daß in der Kohortenabfolge vor allem die Berufsanfänger aufstiegen, die in der Lage waren, in den öffentlichen Dienst einzutreten. Das Nachholen beim Berufseinstieg verpaßter Aufstiege ist kaum möglich, und dies gelingt auch nicht durch die Beschäftigung im öffentlichen Dienst. Für die Wahrscheinlichkeit intergenerationaler Aufstiege im Berufsverlauf gibt es keine sektorspezifischen Unterschiede. Staatsbeschäftigte unterliegen aufgrund der Besitzstandswahrung einem deutlich geringeren Abstiegsrisiko als privatwirtschaftlich Beschäftigte. Der Staatssektor hat seine Funktion als Aufstiegskanal für Berufsanfänger ausgeweitet und garantiert seinen langfristig Beschäftigten die erreichte Statuslage. Damit ist der öffentliche Dienst ein weiteres Strukturprinzip sozialer Ungleichheit.

Comparing growth trajectories of risk behaviors from late adolescence through young adulthood: An accelerated design

Risk behaviors such as substance use or deviance are often limited to the early stages of the life course. Whereas the onset of risk behavior is well studied, less is currently known about the decline and timing of cessation of risk behaviors of different domains during young adulthood. Prevalence and longitudinal developmental patterning of alcohol use, drinking to the point of drunkenness, smoking, cannabis use, deviance, and HIV-related sexual risk behavior were compared in a Swiss community sample (N = 2,843). Using a longitudinal cohort-sequential approach to link multiple assessments with 3 waves of data for each individual, the studied period spanned the ages of 16 to 29 years. Although smoking had a higher prevalence, both smoking and drinking up to the point of drunkenness followed an inverted U-shaped curve. Alcohol consumption was also best described by a quadratic model, though largely stable at a high level through the late 20s. Sexual risk behavior increased slowly from age 16 to age 22 and then remained largely stable. In contrast, cannabis use and deviance linearly declined from age 16 to age 29. Young men were at higher risk for all behaviors than were young women, but apart from deviance, patterning over time was similar for both sexes. Results about the timing of increase and decline as well as differences between risk behaviors may inform tailored prevention programs during the transition from late adolescence to adulthood.

Intergenerational Mobility in Switzerland. A Comparison of Methodological Approaches

Despite the widespread interest in the topic and a vast international literature, only little is known about the development of intergenerational mobility in Switzerland. Based on a new harmonized database for Switzerland (comprising various surveys such as different waves of the ISSP, EVS, or the ESS), we provide a systematic account of changes in the link between social origin and destination over time (covering birth cohorts from 1940 through 1980). We analyze effects of parental education and class on own educational achievement and social class for both men and women, using a refined variant of the methodological approach proposed by Jann and Combet (2012). The approach is based on the concept of proportional reduction of error (PRE) and features a number of advantages over more traditional approaches. For example, it provides smooth estimates of changes in social mobility that have a clear interpretation and it can easily incorporate control variables and multiple dimensions of parental characteristics. To evaluate the validity of our approach, we employ the oft-used log-multiplicative layer effect model (Xie 1992) as a benchmark. Results indicate that our approach performs well and produces qualitatively similar findings as Xie’s model. For men, effects of social origin have been stable over the observed period. For women, however, social mobility significantly decreased among younger cohorts, mostly due to expanding female education and labor force participation. Jann, Ben, Benita Combet (2012).

Heterogeneity in the Relationship between Happiness and Age: Evidence from the German Socio-Economic Panel

This paper studies the evolution of life satisfaction over the life course in Germany. It clarifies the causal interpretation of the econometric model by discussing the choice of control variables and the underidentification between age, cohort and time effects. The empirical part analyzes the distribution of life satisfaction over the life course at the aggregated, subgroup and individual level. To the findings: On average, life satisfaction is mildly decreasing up to age 55 followed by a hump shape with a maximum at 70. The analysis at the lower levels suggests that people differ in their life satisfaction trends, whereas the hump shape after age 55 is robust. No important differences between men and women are found. In contrast, education groups differ in their trends: highly educated people become happier over the life cycle, where life satisfaction decreases for less-educated people.

Geschlechtsspezifische Berufswünsche und Ausbildungsentscheidungen

Dass es geschlechtstypische Berufe gibt, und dass die Berufsaspirationen und die Wahl der Berufsausbildung nach der Pflichtschulzeit zwischen den Geschlechtern deutlich differieren, ist eine vielfach empirisch belegte Tatsache. Diese geschlechtstypische Segregation bei der Berufswahl und der zum ausgewählten Beruf führenden schulischen und beruflichen Ausbildung wird bei der Erklärung oftmals (pauschal) auf die geschlechtsspezifische Sozialisation und darin vermittelte Geschlechterstereotype zurückgeführt. Im vorliegenden Beitrag werden aus strukturell-individualistischer Sicht Mechanismen der geschlechtstypischen Berufsaspiration und Berufsbildungsentscheidung beschrieben, die theoriegeleitet empirisch aufgedeckt werden sollen. Für die Analysen werden Daten der drei Wellen des DAB-Panels verwendet, die für die Deutschschweiz Informationen von 203 Schulklassen mit rund 3.300 Schülerinnen und Schüler zur Verfügung stellen. Mittels dieser Paneldaten wird für Jugendliche der Deutschschweiz gezeigt, dass der sozioökonomische Status des Elternhauses, das damit einhergehende Motiv des intergenerationalen Statuserhalts sowie der Lebenslaufplanungen wichtige Beiträge zur Erklärung der Segregation der Berufswahl nach Geschlecht liefern. Diese mit dem Sozialstatus des Elternhauses verbundenen Mechanismen sind weitaus einflussreicher als die geschlechtsspezifische Sozialisation.

Statusreproduktion und Mobilitätseffekte beruflicher Weiterbildung

Es wird für Westdeutschland untersucht, ob sowohl der intergenerationale Abstieg als auch der intergenerationale Statuserhalt Beweggründe für berufliche Weiterbildung sind. Des Weiteren wird untersucht, ob mit beruflicher Weiterbildung ein intergenerationaler Abstieg ausgeglichen oder das Risiko für intergenerationale Abwärtsmobilität minimiert werden kann. Mit Längsschnittdaten der Deutschen Lebensverlaufsstudie finden sich für westdeutsche Frauen und Männer in fünf aufeinander folgenden Geburtskohorten im Zeitraum von 1949 bis 1999 Indizien dafür, dass das Statuserhaltmotiv ein Weiterbildungsmotiv für Personen sein könnte, die einen intergenerationalen Statusverlust erfahren haben. Mit Weiterbildungsanstrengungen können im weiteren Berufsverlauf intergenerationale Abstiege ausgeglichen werden. Ferner haben statuskonsistente Teilnehmer geringere Risiken für einen intergenerationalen Abstieg als Nichtteilnehmer. Berufliche Weiterbildung hat statusreproduzierende Wirkungen im Berufsverlauf.

Investigating short- and long-term transfer effects of a Taiji beginner course in participants’ daily life

OBJECTIVE: In recent years research investigating various health benefits of Taiji practice has markedly increased. Despite this growing scientific interest, essential questions such as to what extent a Taiji course may exert noticeable effects in participants’ everyday life, what these effects are, and how and where potential transfer effects occur, have hardly been considered. The aim of our study was to explore transfer effects from a Taiji course into participants’ daily lives. METHODS: We conducted a longitudinal observational study in 45 healthy participants at the end of their three-month Taiji beginner course (tp1) and at two months (tp2) as well as one year after course completion (tp3). Participants were asked to report their Taiji practice behavior at all time points, as well as to rate and describe perceived transfer effects of Taiji course contents on their daily life at tp1 and tp3. RESULTS: Transfer effects were reported by 91.1% of all respondents after course completion (tp1) and persisted in 73.3% at the one-year follow-up assessment (tp3), counting “increase of self-efficacy”, “improvement of stress management”, and “increase of body awareness” as the most frequently mentioned effects. Transfer effects predominantly occurred in participants’ work and social environments, as well as during everyday activities in public areas. While selfreliant Taiji practice frequency significantly decreased from 82.2% at tp1 to 55.6% at tp3 (P < 0.001), the magnitude of self-reported transfer effects did not (P = 0.35). As explorative analyses revealed, regular Taiji course attendance was highly correlated with stronger transfer effects at tp1 (r = 0.51; P < 0.001) and tp3 (r = 0.35; P = 0.020). Participants reporting high self-reliant Taiji practice frequency at tp2 were likely to maintain a regular practice routine at tp3 (r = 0.42; P < 0.004), whereas self-reliant practice frequency and transfer effects at tp1 were positively correlated with self-reliant practice frequency at tp3 on a trend level (r < 0.27; P > 0.08). CONCLUSION: Our data underline the importance of regular course participation for pronounced and long lasting transfer effects into participants’ everyday life. We discuss that several context and process-related aspects of a Taiji intervention are potentially relevant factors for enhancement of transfer effect.
