As income levels increase, numerous households will consider investing in risky assets. Credit availability, especially for high-income households, is playing an increasingly important role in enhancing households holdings of risky assets (HHRA). The purpose of this study is to investigate the impact of credit availability on HHRA. In this study, the data from the China Household Finance Survey in 2017 is utilized, and the approach of logit regression is employed to produce more accurate estimates. Meanwhile, this study also explores the heterogeneous roles of household income. The results show that the impact of credit availability on HHRA varies by household income. As household income increases from low to high, the effect of credit availability on HHRA transfers from negative to positive. Besides, the results also suggest that for high-income households, credit availability moderated with the attention to financial and economic information positively contributes to HHRA. Thus, it implies that policymakers and financial institutions are encouraged to expand access for households to invest in risky assets, enhance households’ availability of credit, and build more financing channels.

The establishment of the environmental protection law reflects the Chinese government's determination to achieve ecological civilization. Since January 1, 2015, when the revised Environmental Protection Law of the People's Republic of China came into effect, environmental public interest litigation in China has been rapidly growing. In the implementation of environmental law, environmental public interest litigation plays an irreplaceable role. The mechanism of environmental public interest litigation will ideally enhance the effectiveness and prevention of environmental protection and become a major contributor to public awareness of environmental protection. Despite the fact that environmental public interest litigation in China has made great progress, there are still many shortcomings and defects. One of the major difficulties facing environmental public interest litigation in China is the lack of standing of plaintiffs in environmental public interest litigation. This paper will explore the necessity of plaintiff status for environmental public interest litigation in China's grassroots self-governance organizations based on the situation of environmental pollution in rural China, using village committees as an example.

As global warming continues to intensify, how to prevent climate deterioration has become a serious concern for all countries. In recent years, although China’s GDP has leap to the second place in the world after the United States, it is accompanied by serious problems of environmental pollution and energy consumption with the rapid development of the economy. Under the common goal of global energy conservation and emission reduction, China has established seven carbon trading markets. Because the energy-chemical industry is a major concern for emission reduction and the carbon trading market has market regulation functions, examining the relationship between them is of great significance and can help the emission reduction effort. This study investigates the relationship between the carbon emission price of China's carbon trading market and the stock price of 30 listed companies in the energychemical industry. We use daily data to establish a panel model and var model, and　then compare it with European Emissions Trading Scheme (EU-ETS). The result indicates that there is an asymmetric one-way relationship between the carbon emission price and the stock price of the energy-chemical industry in China. The main reason is that the internal endogenous mechanism and external response mechanism of the carbon trading market are not perfect. Then the government should improve relevant legal system and trading system, and furthermore, introduce third-party institutions and strengthen talent pools.

Consumer capability refers to the ability to apply relevant knowledge and perform desirable behavior for achieving wellbeing. Previous research reveals that consumer behavior is more important than knowledge to indicate consumer capability. How to motivate individual consumers to engage in consumption activities that contribute to sustainable development? This is the question this conceptual paper attempts to address. This paper proposes a definition of sustainable consumer behavior and applies a theory-based, conceptual framework to develop action-taking programs in sustainable consumption education. Sustainable consumer behavior is defined as consumer acts that consider current and future interests of themselves and others when they purchase and use market goods. The behavior change theory used here refers to the transtheoretical model of behavior change (TTM), a commonly used behavior change theory in health and finance. The paper demonstrates how to facilitate the development of sustainable consumer behavior in education intervention programs based on principles outlined in TTM with specific examples. Implications for policies and future research are also discussed.

The purpose of this study was to compare demographic trends in the aging of the Japanese and Brazilian populations on the basis of health indicator data collected by the statistics bureaus of the Japanese and Brazilian governments. The demographic and health indicator data from surveys by the Statistics Bureaus of the Japanese and Brazilian governments and other sources were obtained from websites. The data showed that Japan has an aging population, that the number of elderly persons in Japan is increasing and that the Government of Japan has a plan to address future demands for health resources by this aging population, whereas Brazil has a rapidly population aging but no plan for its future health services. Brazil may need to increase the number of hospitals and hospital beds and develop a medical care plan for the elderly within its Unified Health System.

Histopathological and immunohistochemical studies were conducted to investigate the local existence and distribution of mast cells, fibroblasts or dendritic cells, and myofibroblasts in scleroderma, while paying particular attention to the interstices around the adnexa. The skin tissues in 15 cases of systemic scleroderma were classified histopathologically into three stages: early, fully developed, and late stage. Mesenchymal cells were distinguished immunohistochemically by 6 markers: tryptase, CD34, factor XIIIa, alpha smooth muscle actin (αSMA), vimentin, and desmin. In scleroderma, there was an increase in the number of tryptase-positive mast cells in the interstices around the adnexa. With no relation to the interstitial sites, there was a significant decrease in the number of CD34-positive cells in the late stage, and a significant increase in αSMA-positive cells in the fully developed stage, but a decrease in the late stage. Results of the present study brought about the following new findings: it was only in the mast cells that there was a significant difference in the cell distribution between the interstices around the adnexa and the interstices in non-adnexal sites. Secondly, it was suggested that mast cells, CD34-positive dendritic cells, and αSMA-positive myofibroblasts were involved in the fibrosis and shrinkage or disappearance of the adnexa when scleroderma developed.

Hepatocellular carcinoma (HCC) has a poor prognosis even after curative surgery, due to the high frequency of early intrahepatic recurrence (IHR). Conventional staging systems are almost completely inadequate, and need to be complemented by novel tools. To this end, many investigators have performed DNA microarray analysis on the basis of genome-wide information. However, so far, few studies have been able to truly account for the clinical efficacy of DNA microarray analysis in HCC. To address this dilemma, we used a supervised learning method with information of 7070 genes from 33 HCC samples, to construct a 12-gene predictor for early IHR, and then evaluated its predictive performance in 27 independent HCC samples. Our 12-gene predictor correctly predicted early IHR or non-recurrence in 25 (93%) of the 27 independent samples. This predictive value is higher than that of any other system currently available, suggesting that our system can serve as a robust tool for accurate prediction of early IHR of HCC. I emphasize in this mini-review that, although there are some technical issues to resolve prior to clinical use, DNA microarray technology can provide molecular basis to initiate “bench to bedside” translation, which cannot be easily reached with other methods.

Application of cell therapy using stem cell into intractable diseases has been noted as the medicine in the next generation taking the place of organ transplantation. Bone marrow cells have been focused as a candidate of the source of this therapy. Liver failure is a terminal state of all advanced liver diseases and thousands of patients are dying of decompensated liver cirrhosis in every year in Japan. Liver transplantation must be the strongest weapon to relieve those patients. However, particularly in Japan, liver transplantation has not been popularized. In this sense, we thought of autologous bone marrow cells transplantation for decompensated liver cirrhosis. Basic studies using animal model revealed that transplanted bone marrow cells into syngenic mouse suffering from liver cirrhosis migrated into the damaged liver and transdifferentiated to the hepatocytes. Based upon the animal studies, clinical trial of this new cell therapy supported by the Ministry of Health, Labor and Welfare is ongoing. It is early to estimate this therapy. However, free from liver failure has been observed in some cases.

Zero-determinant strategies are a class of memory-one strategies in repeated games which unilaterally enforce linear relationships between payoffs. It has long been unclear for what stage games zero-determinant strategies exist. We provide a necessary and sufficient condition for the existence of zero-determinant strategies. This condition can be interpreted as the existence of two different actions which unilaterally adjust the total value of a linear combination of payoffs. A relation between the class of stage games where zero-determinant strategies exist and other class of stage games is also provided.

本研究の目的は，文献をもとに「育児困難感」と「育児不安」の用語の整理を行い，今後の支援に繋げる視点を得ることである。検討の結果，「育児困難感」は，実際の母親を取り巻く要因の中で，母親が子どもと対峙することで「母親自身が困っている」状態を示すものと考えられた。また「育児不安」は「育児における漠然とした不安」であり，疲労感や抑うつ状態が生じる可能性や，具体的な対象や問題がない場合でも生じることが考えられた。また「育児困難感」は「相手（子ども）への感情」であり，「育児不安」は「母親自身の不安」であり，2つは質的に異なると考えられ，「育児困難感」と「育児不安」の高低をもとに，5つのタイプに分類を試みた。

本研究は質問紙調査により挫折体験の意味づけとフォーカシング的経験および外傷後成長（Post-Traumatic Growth，以下“PTG”と表記）との関連を検討するものである。パス解析の結果，（1）フォーカシング的経験のうち「体験過程の受容と行動」はPTGを促進すること，（2）挫折体験の意味づけのうち「同化」はフォーカシング的経験の「間が取れている」と「体験過程の確認時間・空間の確保」，「体験過程の受容と行動」を促進し「体験の感受」を抑制すること，また（3）挫折体験の意味づけのうち「調節」は「体験の感受」と「体験過程の受容と行動」を促進すること，（4）人は挫折体験を経験した際，「同化」と「調節」の両方を体験しがちであることが示された。以上より「同化と調節の振り子モデル」が提示され，調節のみならず同化も有機体の実現傾向のあらわれとして位置づけうること，また一見進んでいないようにみえるクライエントのプロセスを受容することが，結果としてプロセスを進めることにつながるうることが示唆された。

本研究の目的は，教員の教育相談研修への参加意欲を高める要因について検討することである。筆者が行った教育相談の継続研修の参加者14名を対象に，研修に継続参加した理由について自由記述による質問紙調査を行った。検討の結果，研修参加の要因として「ニーズや実践とつながる研究内容」「自分を見つめる・他者と共有し受け止められる時間」は「ニーズや実践とつながる研究内容」や「研究方法・環境の工夫」の両方の側面を持つと考えた。

本研究は挫折体験により知覚されたストレスとフォーカシング的態度および自己成長感との関連を検討するものである。パス解析の結果，(1)挫折体験により知覚されたストレスは問題意識性を高め，フォーカシング的態度による吟味のプロセスを経て自己成長感を高めること，(2)挫折体験により知覚されたストレスはフォーカシング的態度を抑制することが示された。あわせて本研究の結果が臨床に示唆する意義について議論した。
