Long-term Impacts of Global Food Crisis on Production Decisions: Evidence from Farm Investments in Indonesia

This paper estimates farmers’ investment response to food price spikes using household panel data collected before and after the 2007/08 food price crisis in Indonesia. We found that an increase in farmers’ terms-of-trade allowed relatively large crop-producing farmers to increase their investments at both extensive and intensive margins. Food price spikes had a significant income effect among farmers whose production surplus is large for market sales. During the food price crisis, large farmers particularly increased machine investments, which saved some labour inputs, pointing to the importance of complementarities between land and machine investments.     

The Effects of Improved Roads on Wages and Employment: Evidence from Rural Labour Markets in Indonesia

This paper examines the impact of road quality on labour supply and wages using household panel data from rural Indonesia. The analysis uses fixed-effect instrumental variable estimation by first differencing two-round panel data. First, road projects are found to increase the transportation speed. Second, the empirical results from intra-village variations of household endowments and labour-market behaviour show that an increase in transportation speed raised wages in both non-agricultural and agricultural employment, and was associated with a decline in working time in agricultural employment, for the households whose members are relatively educated. The findings support potential complementarity between road quality and education, implying that the government’s public investments in roads and education should be coordinated to capture cross-augmenting positive impacts in the long run.     

Analyses of sexual dimorphism of reconstructed pelvic computed tomography images of contemporary Japanese using curvature of the greater sciatic notch, pubic arch and greater pelvis

Three-dimensional pelvic images were reconstructed from multi-slice CT data of contemporary Japanese (males: 124; females: 104, 25-92 years old), and curvature analysis to examine sexual dimorphism was carried out in the great sciatic notch (GSN), the pubic arch and the greater pelvis in the images. Reconstructed pelvic CT images were visualized fairly well and anatomical landmarks were easily recognizable. When calculating the radii (curvature radii) of the best-fit circles for the spline curve lines set along the edges of the GSNs and of the pubic arches, sexes from these regions were correctly identified in 89.1% (males: 93.8%; females: 83.7%) and 94.7% (males: 97.3%; females: 91.8%) of cases, respectively, by setting an appropriate cut-off value. Furthermore, sexing was possible even in deeper regions of the GSN which are relatively resistant to postmortem damage. Curvature radii of the best-fit spheres of greater pelves showed no significant difference between sexes. However, curvature of the best-fit sphere for the left iliac fossa was significantly larger than that of the right one (p<10(-24)) in males, and the ratios were >1.0 in 88% of all male specimens analyzed. Meanwhile, no significant difference was observed among female samples. Although some left-sided dominancy has been reported in 2-dimensional measurements of the human pelvis, this 3-dimensional laterality in males was much more significant, and is a potential index of sex difference.     

Citizen's psychological knowledge,legal knowledge,and attitudes toward participation in the new Japanese legal system,saiban-in seido

A new procedure, saiban-in seido, was introduced in the Japanese criminal court in 2009.1 1. This article was written before the Saiban-in seido started. A mixed tribunal of three professional judges and six lay people selected from a list of voters deliberate the verdict in serious criminal cases such as murder, rape, and arson. This study researched lay people's attitudes toward the new system, their psychological knowledge (e.g. the reliability of eyewitness testimony) and legal knowledge (e.g. ‘presumed innocent’), and the relationship between attitude and knowledge. Study 1 examined the responses of 294 citizens to a questionnaire; 90 responses were examined in Study 2 (both samples consisted of two age groups, i.e. (1) 20s and (2) 40s and 50s, and two education levels, i.e. (1) college or below and (2) university or more. In both studies, respondents showed concerns about their lack of ability and knowledge to become a lay judge. Although legal knowledge was related to attitude – i.e. the more legal knowledge, the less negativity – no relationship was found between psychological knowledge and attitude. Relevant support for citizens to become lay judges was discussed.     

志愿者动机之社会和文化起源——六国大学生调查情况比较

虽然有关志愿者活动的参与以及志愿者动机(Motivationsto Volunteers,以下简称MTV)的研究已经受到许多国家(尤其是美国)的持续关注,但是,从文化和政治背景来解析的研究却鲜见。本文对志愿者活动的社会起源论和信息传递论这两种理论进行了比较,阐述了不同国家志愿者动机的差异,着重分析了来自6个国家具有不同文化背景的5,794名学生各自的反应。所得到的结果有力地支持了信息传递论,与此同时却淡化了社会起源论。文章得出结论:参与志愿者活动系个人的决定,更多地受个人影响,当然某种程度上也受到巨大的社会力量的影响。     

Student outcomes associated with service-learning in a culturally relevant high school program

The Hawaiian Studies Program (HSP) integrates the learning of Hawaiian culture with more traditional secondary curriculum in science, social studies, and English. Students also participate in weekly community service-learning sessions. Fifty-five HSP students and 29 peers (who were not involved in the program), completed a survey measuring: students' connection to, pride in, and responsibility for their community; civic attitudes; and career knowledge and preparedness. HSP teachers, community members, and students were also interviewed about program outcomes. Compared to other peers, HSP students tended to report feeling more connected to their community and school and to agree that they had career-related skills. Participants believed that service- learning contributed to these outcomes by making connections between school and community life and by exposing students to a variety of careers.     

Risk factors of sudden death in the Japanese hot bath in the senior population

A series of experiments were carried out to clarify the cause of death and the risk factors related to sudden death in the Japanese senior population while bathing in a Japanese style "hot bath." The biodynamic changes while bathing were carefully monitored under actual bathing situations occurring in both the winter and summer seasons. We observed double product (DP), total peripheral blood vessel resistance (TPR), cardiac output (CO), and blood vessel compliance (COMP) by measuring blood pressure, heart rate, pulse wave, and electrocardiogram (ECG). The finding of a high level of DP in the elderly suggests that more myocardial oxygen consumption is needed than for young adults, particularly in subjects with arrhythmia. Although the values for TPR and CO changed somewhat during bathing, the changes were considered normal and to be expected. However, more significant and substantial changes were observed during the winter experiment than during the summer experiment, no doubt owing to lower temperature of the bathing room. The value of COMP did not vary significantly between winter and summer subjects. Twelve subjects in the elderly developed ECG changes while bathing such as supraventricular extrasystole or ventricular tachycardia. No clinical significance was found in the biochemical analyses of the blood obtained before and after bathing. In conclusion, some subjects in the elderly showed risky changes in the above parameters and ECG, factors which may partially explain some of the causes of the many reported cases of lapse of consciousness and unexpected sudden death in the elderly while bathing especially in the winter season. Cold climate, hot water immersion, and hydrostatic pressure may affect their physiological compensation along with existing of coronary stenosis or weakness of respiratory function as a normal consequence of advanced age.     

Democracy,Regional Security Institutions,and Rivalry Mitigation: Evidence From Europe,South America,and Asia

The fact that democracies maintain peaceful relations with each other is regarded as one of the few law-like correlations in international relations, but the causes of this empirical phenomenon remain contested. This paper tries to fill this theoretical gap by attributing the remarkable stability between democracies to inter-democratic institutions. At the same time, it contributes to the debate on the need to differentiate among international organizations in order to assess their peace-building effects. We identify transnational and trans-governmental linkages as crucial features that distinguish inter-democratic from traditional institutions with non-democratic or mixed membership. In order to explain these institutions’ peace-building effect, we analyze the impact of international institutions on rivalry mitigation with a view to five pairs of states: France-Germany, Greece-Turkey, Argentina-Brazil, Indonesia-Malaysia, and Japan-South Korea. Those dyads all look back at a history of rivalry, conflict, and mutual threat perceptions, and they are located in highly institutionalized regional settings but vary with regard to their political regime type. The controlled comparison of cases demonstrates that the embeddedness of international institutions in transnational and trans-governmental linkages corresponds to each member's regime type and that these institutional differences are responsible for the varying extent of rivalry mitigation.
