Does the importance of parent and peer relationships for adolescents' life satisfaction vary across cultures?

This study investigated whether the associations between (a) the quality of the parent-child relationship and peer acceptance and (b) early adolescents’ life satisfaction differed depending on the importance of family values in the respective culture. As part of the Value of Children Study, data from a sub-sample of N = 1,034 adolescents (58% female, M age = 13.62 years, SD = 0.60 years) from 11 cultures was analyzed. Multilevel analyses revealed a positive relation between parental admiration and adolescents’ life satisfaction independent of cultural membership. Further, the higher the importance

Adult parent-child relationships: Relationship quality, support, and reciprocity

In accordance with Bengtson's model of intergenerational solidarity (e.g. Bengtson & Roberts, 1991), the interrelations between adult daughters' family values, their perception of the relationship quality with their parents, the support they reported to give to and to receive from their parents, and their perception of reciprocity in intergenerational support exchange were investigated for N = 265 middle-aged women in Germany. It was also asked whether the support given to parents and perceived reciprocity are related to daughters' felt burden as a result of their support. Cross-sectional, self-report data were examined with multiple and multinomial logistic regression analyses. The analyses revealed positive relations between family values, relationship quality, and support to parents. Perceived reciprocity was associated with the exchange of intergenerational support and imbalance in support had negative effects on the relationship quality. Felt burden was predicted by the extent of support and the perceived reciprocity. However, specific correlational patterns depending on the kind of support as well as differences in the importance of mother and father occurred. The findings are discussed against the background of the meaning of family obligations and reciprocity in a Western culture.

Does the educational success of children growing up in stepfamilies differ from children growing up in single parent households?

Within the framework of research into educational inequality, this paper focuses on the educational success of children who experience parental separation prior to the transition from primary into secondary education. Related to this, the first education passage following primary school is observed. The question arises as to whether children growing up in single parent households after parental separation and whether children in this category who in addition experienced the formation of a stepfamily differ from one another and from children growing up in “nuclear families” in regard to their scholastic performance and transition success. For that reason, not only scholastic performance (grades) but also the type of school attended following primary school are of particular interest. Furthermore, differences regarding parental educational decision-making are examined (vgl. Stocké 2007). The analyses are based on data from the longitudinal study "BIKS 8-14" (educational processes, competence development and selection decisions in preschool- and school age) that has been undertaken at the Otto Friedrich University in Bamberg.

Wellbeing

Well-being is an important component of physical and psychological health and an important source for individual development. The article aims to give an overview of different research traditions and definitions of well-being and to outline the basic ideas of research into well-being. It also examines well-being in school, the sources and predictors of well-being, as well as the function of well-being in educational settings. Both student and teacher well-being are considered.

PM2.5-bound oxygenated PAHs, nitro-PAHs and parent-PAHs from the atmosphere of a Chinese megacity: seasonal variation, sources and cancer risk assessment

Polycyclic aromatic compounds (PACs) in air particulate matter contribute considerably to the health risk of air pollution. The objectives of this study were to assess the occurrence and variation in concentrations and sources of PM2.5-bound PACs [Oxygenated PAHs (OPAHs), nitro-PAHs and parent-PAHs] sampled from the atmosphere of a typical Chinese megacity (Xi'an), to study the influence of meteorological conditions on PACs and to estimate the lifetime excess cancer risk to the residents of Xi'an (from inhalation of PM2.5-bound PACs). To achieve these objectives, we sampled 24-h PM2.5 aerosols (once in every 6 days, from 5 July 2008 to 8 August 2009) from the atmosphere of Xi'an and measured the concentrations of PACs in them. The PM2.5-bound concentrations of Σcarbonyl-OPAHs, ∑ hydroxyl + carboxyl-OPAHs, Σnitro-PAHs and Σalkyl + parent-PAHs ranged between 5–22, 0.2–13, 0.3–7, and 7–387 ng m− 3, respectively, being markedly higher than in most western cities. This represented a range of 0.01–0.4% and 0.002–0.06% of the mass of organic C in PM2.5 and the total mass of PM2.5, respectively. The sums of the concentrations of each compound group had winter-to-summer ratios ranging from 3 to 8 and most individual OPAHs and nitro-PAHs had higher concentrations in winter than in summer, suggesting a dominant influence of emissions from household heating and winter meteorological conditions. Ambient temperature, air pressure, and wind speed explained a large part of the temporal variation in PACs concentrations. The lifetime excess cancer risk from inhalation (attributable to selected PAHs and nitro-PAHs) was six fold higher in winter (averaging 1450 persons per million residents of Xi'an) than in summer. Our results call for the development of emission control measures.

The significant effect of endometriosis on physical, mental and social wellbeing: results from an international cross-sectional survey.

STUDY QUESTION To what extent do the management of endometriosis and the symptoms that remain after treatment affect the quality of life in women with the disease? SUMMARY ANSWER Many women with endometriosis had impaired quality of life and continued to suffer from endometriosis-associated symptoms even though their endometriosis has been managed in tertiary care centres. WHAT IS KNOWN ALREADY The existing literature indicates that quality of life and work productivity is reduced in women with endometriosis. However, most studies have small sample sizes, are treatment related or examine newly diagnosed patients only. STUDY DESIGN, SIZE, DURATION A cross-sectional questionnaire-based survey among 931 women with endometriosis treated in 12 tertiary care centres in 10 countries. PARTICIPANTS/MATERIALS, SETTING, METHODS Women diagnosed with endometriosis who had at least one contact related to endometriosis-associated symptoms during 2008 with a participating centre were enrolled into the study. The study investigated the effect of endometriosis on education, work and social wellbeing, endometriosis-associated symptoms and health-related quality of life, by using questions obtained from the World Endometriosis Research Foundation (WERF) GSWH instrument (designed and validated for the WERF Global Study on Women's Health) and the Short Form 36 version 2 (SF-36v2). MAIN RESULTS AND THE ROLE OF CHANCE Of 3216 women invited to participate in the study, 1450 (45%) provided informed consent and out of these, 931 (931/3216 = 29%) returned the questionnaires. Endometriosis had affected work in 51% of the women and affected relationships in 50% of the women at some time during their life. Dysmenorrhoea was reported by 59%, dyspareunia by 56% and chronic pelvic pain by 60% of women. Quality of life was decreased in all eight dimensions of the SF-36v2 compared with norm-based scores from a general US population (all P < 0.01). Multivariate regression analysis showed that number of co-morbidities, chronic pain and dyspareunia had an independent negative effect on both the physical and mental component of the SF-36v2. LIMITATIONS, REASONS FOR CAUTION The fact that women were enrolled in tertiary care centres could lead to a possible over-representation of women with moderate-to-severe endometriosis, because the participating centres typically treat more complex and referred cases of endometriosis. The response rate was relatively low. Since there was no Institute Review Board approval to do a non-responder investigation on basic characteristics, some uncertainty remains regarding the representativeness of the investigated population. WIDER IMPLICATIONS OF THE FINDINGS This international multicentre survey represents a large group of women with endometriosis, in all phases of the disease, which increases the generalizability of the data. Women still suffer from frequent symptoms, despite tertiary care management, in particular chronic pain and dyspareunia. As a result their quality of life is significantly decreased. A patient-centred approach with extensive collaboration across disciplines, such as pain specialists, psychologists, sexologists and social workers, may be a valuable strategy to improve the long-term care of women with endometriosis.

Parent – environmental interactions shape acoustic signatures in tree swallows: a cross-fostering experiment.

Acoustic signatures are common components of avian vocalizations and are important for the recognition of individuals and groups. The proximate mechanisms by which these signatures develop are poorly understood, however. The development of acoustic signatures in nestling birds is of particular interest, because high rates of extra-pair paternity or egg dumping can cause nestlings to be unrelated to at least one of the adults that are caring for them. In such cases, nestlings might conceal their genetic origins, by developing acoustic signatures through environmental rather than genetic mechanisms. In a cross-fostering experiment with tree swallows Tachycineta bicolor, we investigated whether brood signatures of nestlings that were about to fledge were attributable to their genetic/maternal origins or to their rearing environment. We found that the calls of cross-fostered nestlings did not vary based on their genetic/maternal origin, but did show some variation based on their rearing environment. Control nestlings that were not swapped, however, showed stronger brood signatures than either experimental group, suggesting that acoustic signatures develop through an interaction between rearing environment and genetic/maternal effects.

Changes in self-reported symptoms of depression and physical wellbeing in healthy individuals following a Taiji beginner course – Results of a randomized controlled trial

Introduction: Taiji is a mind-body practice being increasingly investigated for its therapeutic benefits in a broad range of mental and physical conditions. The aim of the present study was to investigate potential preventive effects of Taiji practice in healthy individuals with regard to their depressive symptomatology and physical wellbeing. Methods: A total of 70 healthy Taiji novices (mean age 35.5 years) were randomly assigned to a Taiji intervention group, i.e. Taiji beginner course (Yang-Style Taiji, 2 hours per week, 12 weeks) or a waiting control group. Self-reported symptoms of depression (CES-D) and physical wellbeing (FEW-16) were assessed at baseline, at the end of the intervention, as well as two months later. Results: Physical wellbeing in the Taiji group significantly increased when comparing baseline to follow up (FEW-16 sum scale T(27) = 3.94, p = 0.001, 95% CI 0.17 - 0.55). Pearson’s correlation coefficients displayed a strong negative relationship between self-reported symptoms of depression and physical wellbeing (p’s < 0.001, r‘s ≥ -.54). Conclusions: In this randomized controlled trial we found significant evidence that a Taiji beginner course of three months duration elicits positive effects with respect to physical wellbeing in healthy individuals, with improvements pronouncing over time. Physical wellbeing was shown to have a strong relationship with depressive symptoms. Based on these results, the consideration of Taiji as one therapeutic option in the development of multimodal approaches in the prevention of depression seems justifiable.

Linking livelihood strategies with a regional level landscape mosaic to explore trade-offs between forest conservation and human wellbeing in a Madagascar biodiversity hotspot

The north-eastern escarpment of Madagascar contains the island’s last remaining large-scale humid forest massifs surrounded by diverse small-scale agricultural mosaics. There is high deforestation mainly caused by shifting cultivation practiced by local land users to produce upland rice for subsistence. Today, large protected areas restrict land users’ access to forests to collect wood and other forest products. Moreover, they are no more able to expand their cultivated land, which leads to shorter shifting cultivation cycles and decreasing plot sizes for irrigated rice and cash crop cultivation. Cash crop production of clove and vanilla is exposed to risks such as extreme inter-annual price fluctuations, pests and cyclones. In the absence of work opportunities, agricultural extension services and micro-finance schemes people are stuck in a poverty trap. New development strategies are needed to mitigate the trade-offs between forest conservation and human well-being. As landscape composition and livelihood strategies vary across the region, these strategies need to be spatially differentiated to avoid implementing generic solutions, which do not fit the local context. However, up to date, little is known about the spatial patterns of shifting cultivation and other land use systems at the regional level. This is mainly due to the high spatial and temporal dynamics inherent to shifting cultivation, which makes it difficult to monitor the dynamics of this land use system with remote sensing methods. Furthermore, knowledge about land users’ livelihood strategies and the risks and opportunities they face stems from very few local case studies. To overcome this challenge, firstly, we used remote sensing data and a landscape mosaic approach to delineate the main landscape types at the regional level. Secondly, we developed a land user typology based on socio-ecological data from household surveys in 45 villages spread throughout the region. Combining the land user typology with the landscape mosaic map allowed us to reveal spatial patterns of the interaction between landscapes and people and to better understand the trade-offs between forest conservation and local wellbeing. While shifting cultivation systems are being transformed into more intensive permanent agricultural systems in many countries around the globe, Madagascar seems to be an exception to this trend. Linking land cover information to human-environmental interactions over large areas is crucial to designing policies and to inform decision making for a more sustainable development of this resource-rich but poverty-prone context.

Newborn screening for cystic fibrosis - The parent perspective.

BACKGROUND Newborn screening for CF started 01/2011 in Switzerland. We investigated the parents' opinions about the information received, their feelings, and overall approval of the screening. METHODS This is a prospective questionnaire survey of all parents of positively screened children. Parents were phoned by CF-centres and invited for diagnostic investigations. They completed a questionnaire after the visit to the CF-centre. RESULTS From 2011-2013, 246 families received the questionnaire and 138 (56%) replied. Of these 77 (60%) found the information received at birth satisfactory; 124 (91%) found the information provided in the CF-centre satisfactory. Most parents (n=98, 78%) felt troubled or anxious when the CF-centre called, 51 (38%) remained anxious after the visit. Most parents (n=122; 88%) were satisfied with the screening, 4 (3%) were not, and 12 (9%) were unsure. CONCLUSIONS The smooth organisation of the screening process, with personal information by a CF specialist and short delays between this information and the final diagnostic testing, might have contributed to reduce anxiety among parents. Most families were grateful that their child had been screened, and are happy with the process.

Der WHO Wellbeing Index (WHO-5) als Depressivitätsmaß

Der WHO-5 erfasst mit fünf Items psychisches Wohlbefinden, er dient auch als Screeninginstrument zur Erfassung depressiver Symptomatik. Wenige Studien untersuchten diesen Validitätsaspekt jedoch im klinischen Kontext. Ziel der vorliegenden Studie war es, die Messinvarianz des WHO-5 zwischen depressiven und nicht-depressiven Stichproben sowie Art und Spezifität des Zusammenhangs mit Skalen zur Erfassung der Depressionsschwere zu überprüfen. Insgesamt 414 Personen füllten den WHO-5 und das BDI-II aus. Aktuell erfüllten 207 Personen die DSM-IV-Kriterien einer Major Depression (SKID-I). Eine Teilstichprobe erhielt zusätzlich das Beck-Anxiety-Inventory (BAI) und wurde auf der Hamilton-Depression-Rating-Scale (HAM-D) und der Hamilton- Anxiety-Rating-Scale (HAM-A) durch trainierte Rater eingeschätzt. Der WHO-5 wies hohe Messinvarianz bezüglich des Vorliegens/Nichtvorliegens einer Major Depression auf. Er zeigte hohe negative Zusammenhänge mit selbst- und fremdeingeschätzter Depressivität (BDI-II, HAM-D), insbesondere bei milderer und moderater Symptomschwere und auch nach Kontrolle gleichzeitig bestehender Angstsymptomatik. Diese Ergebnisse unterstützen die Verwendung des WHO-5 als Depressionsmaß, zumindest im Bereich milder und mittlerer Depressionsschwere.

Selective sampling during catastrophic disruption: Mapping the location of reaccumulated fragments in the original parent body

In this paper, we simulate numerically the catastrophic disruption of a large asteroid as a result of a collision with a smaller projectile and the subsequent reaccumulation of fragments as a result of their mutual gravitational attractions. We then investigate the original location within the parent body of the small pieces that eventually reaccumulate to form the largest offspring of the disruption as a function of the internal structure of the parent body. We consider four cases that may represent the internal structure of such a body (whose diameter is fixed at 250 km) in various early stages of the Solar System evolution: fully molten, half molten (i.e., a 26 km-deep outer layer of melt containing half of the mass), solid except a thin molten layer (8 km thick) centered at 10 km depth, and fully solid. The solid material has properties of basalt. We then focus on the three largest offspring that have enough reaccumulated pieces to consider. Our results indicate that the particles that eventually reaccumulate to form the largest reaccumulated bodies retain a memory of their original locations in the parent body. Most particles in each reaccumulated body are clustered from the same original region, even if their reaccumulations take place far away. The extent of the original region varies considerably depending on the internal structure of the parent. It seems to shrink with the solidity of the body. The fraction of particles coming from a given depth is computed for the four cases, which can give constraints on the internal structure of parent bodies of some meteorites. As one example, we consider the ureilites, which in some petrogenetic models are inferred to have formed at particular depths within their parent body. (C) 2014 Elsevier Ltd. All rights reserved.
