This paper empirically examines the impacts of household debt and　leverage ratio, measured by the ratio of aggregate household debt to GDP, on consumption using provincial-level macro-data in China. Results show that household indebtedness has a positive and significant effect on consumption expenditure and this remains true for both household debt and leverage ratio, as well as long-term and short-term debts and leverage ratios, and the encouraging effects are heterogeneous across regions. When the debt-to-GDP ratio is below 100%, the consumption experiences faster growth than that when the debt-to-GDP ratio exceeds 100%. In addition, residents’ saving, per capita disposal income and the public expenditure on education, social security, as well as medical and health services are found to have significant positive effects on consumption, while CPI and child dependency ratio have depressive effects.

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.

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。

The quadratic unconstrained binary optimization (QUBO) problem is categorized as an NP-hard combinatorial optimization problem. The variable neighborhood search (VNS) algorithm is one of the leading algorithms used to solve QUBO problems. As neighborhood structure change is the central concept in the VNS algorithm, the design of the neighborhood structure is crucial. This paper presents a modified VNS algorithm called "B-VNS", which can be used to solve QUBO problems. A binomial trial was used to construct the neighborhood structure, and this was used with the aim of reducing computation time. The B-VNS and VNS algorithms were tested on standard QUBO problems from Glover and Beasley, on standard max-cut problems from Helmberg-Rendl, and on those proposed by Burer, Monteiro, and Zhang. Finally, Mann-Whitney tests were conducted using α = 0.05, to statistically compare the performance of the two algorithms. It was shown that the B-VNS and VNS algorithms are able to provide good solutions, but the B-VNS algorithm runs substantially faster. Furthermore, the B-VNS algorithm performed the best in all of the max-cut problems, regardless of problem size, and it performed the best in QUBO problems, with sizes less than 500. The results suggest that the use of binomial distribution, to construct the neighborhood structure, has the potential for further development.

Incontinentia pigmenti (IP; OMIM# 308300) is a rare inherited disease caused by a mutation of IKBKG, which is also known as NEMO, located on Xq28. IP patients usually present with abnormalities of skin, eyes, nails and central nervous system. The neurological damege, which occur usually from neonatal through the early infantile period, leads to neulogical complication such as development retardation, motor paralysis and epilepsy. However, there has been little study done concerning the effect of therapy for the neural abnormalities. We have investigated the clinical findings in a female IP case with a novel mutation of IKBKG for six years due to disclosing the neurological prognosis and the immunological features. It is hoped that the present study will contribute to a better management of IP patients.
