Data of a national survey, Japan Youth Risk Behavior Survey 2011, was used for this analysis. The subjects were 9778 students (5027 males, 4751 females) in grades 10-12 in 102 schools randomly selected from among high schools throughout Japan. When multiple regression analysis was carried out using four subdomains of norm-consciousness and three subdomains of resilience as the independent variables and nine risk behaviors as the dependent variables, the subdomains of norm-consciousness showed significant positive standardized partial regression coefficients for eight risk behaviors for both males and females. In particular, “current alcohol use” and “ever had sexual intercourse” showed the largest standardized partial regression coefficients for the norm-consciousness in school, and “current cigarette use” showed that for the norm-consciousness in community. The subdomains of resilience showed significant positive standardized partial regression coefficients for five risk behaviors for males and for six those for females. The results of this study suggest that the norm-consciousness is an important protective factor to comprehensively prevent risk behaviors among Japanese adolescents. It is expected to be effective to enhance the norm-consciousness particularly in school and community. In addition, resilience should also be emphasized as a factor to prevent specific risk behaviors.展开更多

Experimental results showed that the distribution of peak seismic earth pressures along the height of a wall was a single peak value curve. The seismic earth pressures on a gravel soil retaining wall were larger than the pressures on the weathered granite and quartz retaining walls. Also, the peak seismic earth pressure increased with increases in the peak ground acceleration and the wall height. The measured seismic active earth pressures on a rock foundation retaining wall were larger than the calculated values, and the action position of resultant seismic pressure was higher than 0.33 H. In the soil foundation retaining wall, the measured seismic earth pressures were much smaller than the calculated values, while the action position was slightly higher than 0.33 H. The soil foundation retaining wall suffered base sliding and overturning under earthquake conditions, while overturning was the main failure mode for the rock foundation retaining walls.展开更多

We offer several explanations for why brain-based differences amid normative performance may be of interest to researchers and clinicians. First, neural processing in the clinical group may not be as efficient as that in the control group. Second, differences in activation could reveal important differences in the cognition behind the (normative) behavior. Third, differences in activation may be prognostic biomarkers of injury or decline. In addition, we contend that similar behavior between groups is important in properly interpreting brain data. Finally, we offer caveats and future directions to further clarify brain mechanisms underlying behavior in clinical populations.展开更多

It is discovered that development of effects of aspirin resembles that of acetylsalicylate zinc. Acetylsalicylate cobalt at extremely low doses zone showed the highest antidepressant activity, demonstrating toxicity at high doses. Generally, it is revealed that the use of aspirin and its salts at high doses range causes maximum psychotropic effects development, usually accompanied by side-effects. Therefore, aspirin, acetylsalicylate cobalt and zinc at extremely low doses are recommended for further study as psychotropic medications.展开更多

Interventions undertaken without understanding the critical factors may not produce the desired results. Objective: The objective of this study was to identify the factors associated with adolescent risky sexual behavior among school adolescents in Addis Ababa, Ethiopia. Methods: This cross-sectional study was done among randomly selected school adolescents in Addis Ababa, Ethiopia. Data were collected by an anonymous self administered questionnaire. Risky sexual behavior was assessed by asking question about sexual activity, consistent condom use and faithfulness to a single partner. Logistic regression analysis was done to identify factors related to sexual behavior using the ecological framework. Result: Overall 377(10.6%) of the 723 sexually active students were involved in risky sexual practices. Risky sexual behavior was significantly and very strongly associated with perception of peers' involvement in sexual intercourse [AOR = 11.68 (95% CI: 8.76 - 15.58)]. Conclusion: This study demonstrated that peer pressure is the most important factor associated with risky sexual behavior among school adolescents in Addis Ababa. Interventions aimed at reducing sexual behavior among school adolescents should target adolescents as a group rather than individually.展开更多

In this paper,based on TPB( Theory of Planed Behavior),using factor analysis and regression analysis,empirical test on formation mechanism of farmer production consumption ecologization behavior transformation is conducted. Research results show that behavior attitude,subjective norm and control cognition of farmer production consumption ecologization have significantly positive influences on behavior response of farmer production consumption ecologization. Among them,power of behavior attitude is farmer's economic rationality and ecological rationality; power of subjective norm is system norm,government guidance and social pressure; power of control cognition is policy judgment and ability perception. Finally,for the analyzed conclusions,policy suggestions are proposed from many aspects,which could provide reference effect for guiding farmer production consumption ecologization and establishing rural eco-civilization.展开更多

Among them,power of behavior attitude is farmer's economic rationality and ecological rationality; power of subjective norm is system norm,government guidance and social pressure; power of control cognition is policy judgment and ability perception. Finally,for the analyzed conclusions,policy suggestions are proposed from many aspects,which could provide reference effect for guiding farmer production consumption ecologization and establishing rural eco-civilization.
