Adolescents’ willingness for intergenerational support: Relations to maternal expectations and mothers’ life satisfaction in 14 cultures

How is adolescents’ willingness for intergenerational support affected by parents’ expectations and parenting behavior? Does youths’ willingness for intergenerational support in turn affect parents’ well-being? The current study addresses these questions from a cross-cultural perspective, using data from connected samples of mother-adolescent dyads (N = 4162) from 14 diverse cultural contexts as part of the “Value of Children and Intergenerational Relations Study” (Trommsdorff & Nauck, 2005). The results are based on mixed model analyses (with culture as a random factor). Associations were investigated between family norms (expectations of support by adult children), parenting goals (obedience, independence) and parenting behavior (acceptance, control) reported by mothers and adolescents’ reports on willingness to support (help in household tasks, willingness to tolerate burdens in order to help their parents in case of accident, emotional support given to mothers and fathers). Across cultures, maternal expectations of adult children were positively related to adolescents’ reported household help and their current emotional support to mothers and fathers. Obedience, and control were positively related to the amount of adolescent help in the household, while independence and acceptance were related to a higher willingness to tolerate burdens as well as to higher emotional support given to the mother. Regarding associations between adolescents’ actual and intended intergenerational support with mothers’ life satisfaction, adolescents’ willingness to tolerate burdens was related to a higher maternal life satisfaction while adolescents’ reported household help was not. Adolescents’ current emotional support to fathers (but not to mothers) was also related to higher maternal life satisfaction. While most of the effects were stable across cultures (no significant random slope variance across cultural groups), some effects did significantly vary across cultures. Traditional-vs.-secular values as culture-level characteristics will be discussed as explanation for these culture-specific relations among mothers’ expectations, adolescents’ intergenerational support, and mothers’ life satisfaction.

A study of the relationship of support systems and adolescent pregnancy outcomes in an adolescent family life project

This study analyzed the relationship of family support systems and adolescent pregnancy outcomes. The population for the study was 390 adolescents who had attended the Marion County Health Department Adolescent Family Life Project in Indianapolis, Indiana during a two-year period.^ The study is unique in that it afforded the opportunity to compare adolescent pregnancy-related characteristics, of white and non-white adolescents in the same study.^ The pregnancy outcomes studied were: Infant birthweight, school attendance, and pregnancy recidivism.^ Significant results were found in the analysis that supported other research in regard to factors that are associated with school attendance when family support, adolescent's age, and ethnicity were controlled. Infant birthweight and repeat pregnancy outcome relationships were not found to have any consistently significant relationship with independent variables anticipated to be associated. However, the comparisons of infant birthweight among the adolescents with, and without, family support, by ethnicity resulted in some interesting findings. Repeat pregnancy proved an enigma, in that there seemed to be almost no variables in this study that were associated with the adolescent having a repeat pregnancy.^ Familial support in this study seemed to be of less importance as a factor in adolescent pregnancy outcomes than was ethnicity. The non-white adolescents in this study had a better record for remaining in school, both those non-white adolescents who lived with parents, and those who did not live with parents. More low birthweight occurred in the non-white adolescent, both those adolescents who lived with parents, and those who did not live with parents. Repeat pregnancy occurred more in the non-white adolescent whether she lived with parents, or did not live with parents. ^

Life cycle assessment as a policy-support tool: the case of taxis in the city of Madrid

This paper examined the potentialities of Life Cycle Assessment (LCA) as instrument for policy-support. To this respect, the adoption of an initiative within the Madrid Air Quality Plan (AQP) 2011–2015 regarding the substitution of diesel taxis with hybrid, natural gas and LPG alternatives was studied. Four different scenarios were elaborated, a business-as-usual scenario (BAU), the scenario of the AQP, and two extreme-situation scenarios: all-diesel (ADI) and all-ecologic (AEC). Impacts were characterized according to the ILCD methodology, focusing especially on climate change (CC) and photochemical ozone formation (PO). SimaPro 7.3 was used as analysis and inventory-construction tool. The results indicate that the shift to ecologic alternatives reduced impacts, especially those related to CC and PO. For the complete life cycle, reductions of 13% (CC) and 25% (PO) were observed for AQP against BAU (CC:1365 GgCO2, PO:13336 MgNMVOC). Deeper reductions were observed for AEC (CC:34%, PO:59%), while ADI produced slight increases in impacts if against BAU. The analysis of the use-phase revealed that the central and highest speed zones of the city benefit from the adoption of AQP. This is especially evident in zone 7, with reductions of 16% in CC and 31% in PO respectively against BAU (CCzone1:3443 kgCO2/veh·km, POzone7:11.1 kgNMVOC/veh·km).

Spontaneous heterosis in larval life-history traits of hemiclonal frog hybrids

European water frog hybrids Rana esculenta (Rana ridibunda × Rana lessonae) reproduce hemiclonally, transmitting only their ridibunda genome to gametes. We compared fitness-related larval life-history traits of natural R. esculenta from Poland with those of the two sympatric parental species and of newly generated F1 hybrids. Compared with either parental species, F1 hybrid offspring had higher survival, higher early growth rates, a more advanced developmental stage by day 49, and earlier metamorphosis, but similar mass at metamorphosis. R. esculenta from natural lineages had trait values intermediate between those of F1 offspring and of the two parental species. The data support earlier observations on natural R. esculenta that had faster larval growth, earlier metamorphosis, and higher resistance to hypoxic conditions compared with either parental species. Observing larval heterosis in F1 hybrids in survival, growth rate, and time to metamorphosis, however, at an even higher degree than in hybrids from natural lineages, demonstrates that heterosis is spontaneous and results from hybridity per se rather than from subsequent interclonal selection; in natural lineages the effects of hybridity and of clonal history are confounded. This is compelling evidence for spontaneous heterosis in hybrid clonals. Results on hemiclonal fish hybrids (Poeciliopsis) showed no spontaneous heterosis; thus, our frog data are not applicable to all hybrid clonals. Our data do show, however, that heterosis is an important potential source for the extensively observed ecological success of hybrid clonals. We suggest that heterosis and interclonal selection together shape fitness of natural R. esculenta lineages.

Prevention of cardiovascular and renal pathology of aging by the advanced glycation inhibitor aminoguanidine.

Human aging is impacted severely by cardiovascular disease and significantly but less overtly by renal dysfunction. Advanced glycation endproducts (AGEs) have been linked to tissue damage in diabetes and aging, and the AGE inhibitor aminoguanidine (AG) has been shown to inhibit renal and vascular pathology in diabetic animals. In the present study, the effects of AG on aging-related renal and vascular changes and AGE accumulation were studied in nondiabetic female Sprague-Dawley (S-D) and Fischer 344 (F344) rats treated with AG (0.1% in drinking water) for 18 mo. Significant increases in the AGE content in aged cardiac (P < 0.05), aortic (P < 0.005), and renal (P < 0.05) tissues were prevented by AG treatment (P < 0.05 for each tissue). A marked age-linked vasodilatory impairment in response to acetylcholine and nitroglycerine was prevented by AG treatment (P < 0.005), as was an age-related cardiac hypertrophy evident in both strains (P < 0.05). While creatinine clearance was unaffected by aging in these studies, the AGE/ creatinine clearance ratio declined 3-fold in old rats vs. young rats (S-D, P < 0.05; F344, P < 0.01), while it declined significantly less in AG-treated old rats (P < 0.05). In S-D but not in F344 rats, a significant (P < 0.05) age-linked 24% nephron loss was completely prevented by AG treatment, and glomerular sclerosis was markedly suppressed (P < 0.01). Age-related albuminuria and proteinuria were markedly inhibited by AG in both strains (S-D, P < 0.01; F344, P < 0.01). These data suggest that early interference with AGE accumulation by AG treatment may impart significant protection against the progressive cardiovascular and renal decline afflicting the last decades of life.

Support groups and cardiac rehabilitation: Effects of partner participation on anxiety and depression

This study analyzes the effect on levels of patient anxiety and depression of a partner joining a cardiac rehabilitation program support group, also taking into account the sex of the patient. The study was undertaken using a two-group comparison design with pre-and post-test measures in non-equivalent groups. The sample comprised patients in the cardiac rehabilitation program (CRP) at the Ramón y Cajal Hospital, Madrid (Spain). Analysis of covariance (ANCOVA) showed direct effects of sex and partner participation in support groups on the anxiety trait. Similarly, interaction effects were observed between the sex variable and partner participation. These results indicate the pertinence of designing separate groups for patients and partners. © 2014 Universidad Complutense de Madrid and Colegio Oficial de Psicólogos de Madrid.

Life Experiences of People Affected by Crohn’s Disease and Their Support Networks Scoping Review

This scoping review identifies and describes relevant studies related to the evidence published on life experiences and perceived social support of people affected by Crohn’s disease. Twenty-three studies were definitely selected and analyzed for the topics explored. The overall findings show patients’ needs and perceptions. There is a lack of evidence about patients’ perceived needs as well as the understanding of social support that has contributed to improve their life experiences with that chronic illness. Lack of energy, loss of body control, body image damaged due to different treatments and surgeries, symptoms related to fear of disease, feeling burdened loss related to independence, and so on are some of the concerns with having to live with those affected by the Crohn. To underline those experiences through this scoping review provides valuable data for health care teams, especially for the nursing profession, considered by those affected as one of the main roles along the whole pathological process. This review provides the basis for developing broader research on the relatively underexplored topics and consequently improves specific programs that could address patients’ needs.
