Interdependent self-construal moderates the relationship between pro-generation investment and future orientation: A cross-cultural comparison.

INTRODUCTION: Cultural orientation and interdependent self-construal can moderate the relationship between perceived pro-generation investment and future orientation of young adults. To test how interdependent self-construal moderate the relationship between pro-generation investment and future orientation of young adults from two different cultural ecologies was the aim of the current study. METHODS: A cross-cultural comparison was conducted among study participants from China, Germany, and the United States. Interdependent self-construal, perceived pro-generation investment by parents (parental investment), and future orientation were measured. Cross-cultural data were collected from 205 college students in China, a collectivist culture, and 169 college students in Germany (n = 50) and the United States (n = 119), which are individualist cultures. We examined a three-way interaction with cultural orientation and interdependent self-construal as moderators in the relationship between perceived parental investment and future orientation. RESULTS: In the collectivist cultural context, there appeared no moderating effect of interdependent self-construal on the relationship between perceived parental investment and future orientation, although interdependent self-construal and perceived parental investment predicted future orientation. In the individualistic cultural context, there was a moderating effect. For individuals high in interdependent self-construal, future orientation remained stable as perceived parental investment increased. For individuals low in interdependent self-construal, future orientation decreased as perceived parental investment increased. CONCLUSIONS: The findings have practical implications in that parents should follow the cultural orientation of their background and provide their children with individualized investment and education to shape the future orientation of their offspring.

Effects of connection-based physician-patient relationships on perceptions of outcome: A vignette experiment.

OBJECTIVES: To investigate the effects of media reports of medical outcomes and connection-based medicine on trust in physicians. In "connection-based medicine," people use personal connections to obtain better medical resources. METHODS: Vignette experiments were used to investigate attitudes toward physicians among 230 cancer patients and their families (Sample 1) and a cross-validated sample of 280 employees from various industries (Sample 2). RESULTS: For both samples, negative media reports were associated with lower trust in physicians; when the reports were positive, the participants generally perceived physicians as more competent and trustworthy. However, with negative reports, patients and families perceived connection-based physicians as less right and professional than non-connection-based physicians; the public (represented by the employee sample) perceived connection-based physicians as less right than non-connection-based physicians and negative outcomes to be caused more by connection-based physicians than non-connection-based physicians. CONCLUSIONS: Medical reports can influence the perception of a physician's traits, which are important for trust. Positive reports promote evaluation of Rightness, Attribution, and Professionalism, whereas negative results may elicit the opposite effect, especially for connection-based physicians. PRACTICAL IMPLICATIONS: Positive media images of physicians can help facilitate trust. Connection-based medical treatment should be reduced to improve access to medical resources in China.

Reference Intervals of Serum Iodine Concentration in Chinese Pregnant Women.

The study aims to establish trimester-specific reference ranges for serum iodine (SI) in Chinese pregnant women and explore its associations with maternal and infantile thyroid function. Apparently healthy pregnant women were enrolled during their first antenatal visit. Fasting venous and spot urine samples were collected for determining serum and urinary iodine (UI) levels by a validated inductively coupled plasma mass spectrometry. Serum free triiodothyronine (FT3), free thyroxine (FT4), thyrotropin (TSH), and neonatal TSH levels were tested by electro-chemiluminescent assay. The reference ranges of SI were established by percentile method and reported as 2.5-97.5%. ROC analysis was applied to compare the discriminative ability of SI, UI, and UI to urinary creatine ratio (UI /UCr) in early pregnancy for various thyroid conditions. The trimester-specific reference ranges of SI for Chinese pregnant women were 60.91-114.53 µg/L for the first trimester (T1, n = 1029), 54.57-103.42 µg/L for the second trimester (T2, n = 379), and 52.03-110.40 µg/L for the third trimester (T3, n = 455). Maternal SI at T1 but not UI and UI/UCr was significantly correlated with FT3 (r = 0.393, P < 0.001), FT4 (r = 0.637, P < 0.001), and TSH (r = -0.299, P<0.001). Maternal SI change% from T1 to T2 (but not SI change% from T1 to T3) had marginal correlation with neonatal TSH (r=-0.106, P=0.046). ROC analysis showed that maternal SI at T1 had better predictability for several thyroid conditions than UIC and UI/UCr.

Functional Properties of Protein Hydrolysates on Growth, Digestive Enzyme Activities, Protein Metabolism, and Intestinal Health of Larval Largemouth Bass (Micropterus salmoides).

The present study was conducted to investigate the effects of dietary inclusion of protein hydrolysates on growth performance, digestive enzyme activities, protein metabolism, and intestinal health in larval largemouth bass (Micropterus salmoides). The experimental feeding trial presented in this study was based on five isonitrogenous and isolipidic diets formulated with graded inclusion levels of protein hydrolysates, and it showed that protein hydrolysates improved growth performance, reduced larval deformity rate, and increased the activity of digestive enzymes, including pepsin and trypsin. Gene expression results revealed that the supplementation of protein hydrolysates upregulated the expression of intestinal amino acid transporters LAT2 and peptide transporter 2 (PepT2), as well as the amino acid transporters LAT1 in muscle. Dietary provision of protein hydrolysates activated the target of rapamycin (TOR) pathway including the up-regulation of TOR and AKT1, and down-regulation of 4EBP1. Additionally, the expression of genes involved in the amino acids response (AAR) pathway, ATF4 and REDD1, were inhibited. Protein hydrolysates inhibited the transcription of some pro-inflammatory cytokines, including IL-8 and 5-LOX, but promoted the expression of anti-inflammatory cytokines TGF-ß and IL-10. The 16S rRNA analysis, using V3-V4 region, indicated that dietary protein hydrolysates supplementation reduced the diversity of the intestine microbial community, increased the enrichment of Plesiomonas and reduced the enrichment of Staphylococcus at the genus level. In summary, protein hydrolysates have been shown to be an active and useful supplement to positively complement other protein sources in the diets for largemouth bass larvae, and this study provided novel insights on the beneficial roles and possible mechanisms of action of dietary protein hydrolysates in improving the overall performance of fish larvae.
