Glass-Si heterojunction solar cells

An increase in efficiency from 2% to over 7% was achieved by a solar cell that used polycrystal silicon heterojunction with SnO2 glass. For Single crystal substrates, efficiencies close to 10% were measured. These cells had the same structures as polycrystalline cells. Work on p+/n heterojunction using In2O3 glass resulted in cells of 3% efficiency on polycrystalline material and 4% efficiency on single crystal material

Coparenting after marital dissolution and children's mental health: a systematic review

Research has shown that coparenting is a vital family mechanism in predicting mental health in children and adolescents. Considering the increasing prevalence of marital dissolution in Western societies, the objective of this systematic review was to summarize the key results of empirical studies that tested the association between mental health of children and coparenting after marital dissolution.info:eu-repo/semantics/publishedVersio

The Portuguese version of the Psychological Adjustment to Separation Test-Part A (PAST-A): a study with recently and non-recently divorced adults

Past research has demonstrated that divorced adults show more health problems and psychological distress than married adults. Considering the high prevalence rates of divorce among Western countries, new and robust measures should be developed to measure psychological distress after this specific transition in adulthood. The aim of this study was to adapt and validate a Portuguese version of the Psychological Adjustment to Separation Test-Part A (PAST-A; Sweeper and Halford in J Family Psychol 20(4):632–640, 2006). PAST-A is a self-report measure that assesses two key dimensions of separation adjustment problems: lonely-negativity and former partner attachment. Psychometric properties of the Portuguese version of PAST-A were assessed in terms of factor structure, internal consistency, and convergent and divergent validity, in an online convenience sample with divorced adults (N = 460). The PAST-A two-factor structure was confirmed by exploratory and confirmatory factor analyses, with each factor demonstrating very satisfactory internal consistency and good convergence. In terms of discriminant validity, the Portuguese PAST-A reveals a distinct factor from psychological growth after divorce. The results provided support for the use of the Portuguese PAST-A with divorced adults and also suggested that the explicative factors of the psychological adjustment to divorce may be cross-cultural stable. The non-existence of validated divorce-related well-being measures and its implications for divorce research are also discussed

Divorce, conflict and mental health: how the quality of intimate relationships is linked to post-divorce well-being

Partner relationships, including new relationships after divorce, are found to be beneficial for mental health. However, the impact of their quality remains unclear; this uncertainty applies to past and ongoing relationships between ex-spouses as well. We study the relationship between conflict—in the prior marriage, with the ex-partner, with a new partner—and both positive and negative mental health. Multilevel linear models are carried out on a subsample of 892 divorcees from the dataset “Divorce in Flanders.” Living together with a new partner, either in marriage or cohabitation, seems beneficial for mental health, even in cases of (high) conflict. Nevertheless, conflict places a burden on well-being, especially for women in non-marital relationships. Ongoing conflict with the ex-spouse is also damaging for mental health. In contrast, prior marital conflict does not relate to lower, but to slightly higher, levels of life satisfaction after divorce

Single parenting: Interventions in the transitional stage

Following divorce or separation, many mother-headed families need to mourn losses, including reduced economic resources. They need to reestablish family rituals, confront such issues as time management and structural changes that can result in scapegoating or over-reliance on a parental child. Normalizing difficulties associated with parenting is important because single parents tend to internalize societal attribution of family difficulties to inadequate family structure rather than developmental stages, limited economic resources, and negative expectations about the capacity of women to head families.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44289/1/10591_2004_Article_BF00891869.pd

Integrating a family-focused approach into child obesity prevention: Rationale and design for the My Parenting SOS study randomized control trial

<p>Abstract</p> <p>Background</p> <p>More than 20% of US children ages 2-5 yrs are classified as overweight or obese. Parents greatly influence the behaviors their children adopt, including those which impact weight (e.g., diet and physical activity). Unfortunately, parents often fail to recognize the risk for excess weight gain in young children, and may not be motivated to modify behavior. Research is needed to explore intervention strategies that engage families with young children and motivate parents to adopt behaviors that will foster healthy weight development.</p> <p>Methods</p> <p>This study tests the efficacy of the 35-week My Parenting SOS intervention. The intervention consists of 12 sessions: initial sessions focus on general parenting skills (stress management, effective parenting styles, child behavior management, coparenting, and time management) and later sessions apply these skills to promote healthier eating and physical activity habits. The primary outcome is change in child percent body fat. Secondary measures assess parent and child dietary intake (three 24-hr recalls) and physical activity (accelerometry), general parenting style and practices, nutrition- and activity-related parenting practices, and parent motivation to adopt healthier practices.</p> <p>Discussion</p> <p>Testing of these new approaches contributes to our understanding of how general and weight-specific parenting practices influence child weight, and whether or not they can be changed to promote healthy weight trajectories.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov: <a href="http://www.clinicaltrials.gov/ct2/show/NCT00998348">NCT00998348</a></p
