The present study examined the longitudinal links between perceptions of family connectedness and body satisfaction in 1,774 (52% female) adolescents. Participants (10–15 years of age at Time 1) completed self-report measures at three measurement occasions separated by 1 year each. Mean group difference results showed that both body satisfaction levels and perceived levels of family connectedness decreased over 2 years for the whole sample. As expected, girls were generally less satisfied with their bodies than boys, particularly in the older cohort. Structural equation modelling was used to assess stability coefficients and cross-lagged effects, and longitudinal bidirectional effects between perceptions of family connectedness and body satisfaction were found for girls, but not for boys. This result suggests that adolescent girls’ body satisfaction is both affected by and a predictor of perceived family connectedness.  相似文献

The population grows and ages. Older adults, which is the group of people sixty years of age and older, increasingly represents a numerically larger group. Therefore, the legal rules are issued, and must be of such a nature that adequately protects them. In particular labor standards in Mexico, containing general provisions, but are emissive in relation to work of older adults subordinate.  相似文献

In this paper, we examine and compare the two important production hubs in Asia: China and Greater China and India and South Asia. We show that in China, Hong Kong and Taiwan, manufacturing trade has continued to be highly relevant, with trade in parts and components growing in importance. In contrast, in India, Pakistan and Sri Lanka, trade in parts and components remain limited. We then calculate various revealed comparative advantage (RCA) indices, which China having more components with RCA values exceeding one. Some of the most important components exported by China include electronic parts and telecommunication parts. One explanation is to why India is relatively weak in parts and components trade is that India is strong in service trade. Other reasons may be related to better port infrastructure, higher research and development intensity and higher educational enrollments in China.  相似文献

Allele frequencies for eight STRs (CD4, FES/FPS, MBPB, TH01, TP53, TPO, F13A1, VWA) were estimated from samples (sized between 279 and 328) of unrelated individuals born in S. Tomé e Príncipe (Gulf of Guinea, West Africa).  相似文献

In the last thirty years, historic centres that were considered as impoverished urban structures that ought to be replaced are now viewed as crucial enclaves of urban identity that ought to be protected. The singularity of the old city increases its importance in our global world. The value of the city as a living cultural legacy, with all its embedded symbolism, is thus recognised. We can find some problems within these spaces, as for example, depopulation and dwelling price increase with their consequences: degradation in some parts and revaluation in others, especially in those with progressive increase in the service economy.  相似文献

AIM:To evaluate the Z-line visualization by the PillCamTM SB2 using three different ingestion protocols. METHODS:Ninety consecutive patients undergoing small bowel capsule endoscopy(SBCE)between January and May 2008 were included in the study. They swallowed the capsule in the standing(Group A= 30),supine(Group B=30)and right supine positions (Group C=30).Baseline patient characteristics, difficulties in capsule ingestion,esophageal transit times(ETT)and Z-line visualization were noted. RESULTS:No significa...  相似文献

Haplotype and allele frequencies of the nine Y-STR (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS385 I/II) were determined in a population sample of 200 unrelated males from Belém, Brazil. The most common haplotypes are shared by 1.5% of the sample, while 186 haplotypes are unique. The haplotype diversity is 0.9995+/-0.0006. The data obtained were compared to those of other Brazilian populations. AMOVA indicates that 99.91% of all the haplotypical variation is found within geopolitical regions and only 0.09% is found among regions.  相似文献
