The recent advances in assisted reproductive technology, such as hormonal stimulation, IVF, and intracytoplasmic sperm injection (ICSI), have made it possible to circumvent many causes of male and female factor infertility. However, uterine infertility is still considered an ‘‘unconditionally infertile’’ condition. Owing to the continued advances in organ transplantation, microvascular anastomosis techniques, and immunosuppressive medicine, the transplantation of organs is no longer restricted to the ones necessary for continued life. Quality-of-life enhancing types of transplantation, such as uterine transplantation, in recent (...) years, have also entered the clinical arena. This undoubtedly brings new hope to such women, but also creates ethical challenges. Selection of the donor, the impact on the recipient and offspring, as well as challenges to moral and social norms are issues that cannot be ignored. In the present review, the ethical issues of transplantation of the uterus will be discussed in light of recent progress in the procedure. (shrink)

本書屬於比較哲學的工作，它涉及德國、中國與韓國的倫理學思考。第一、二章首先藉由梳理康德早期倫理學經由席勒倫理學到現象學倫理學的發展過程及其內在理路。此一發展涉及倫理學的基本問題：我們對於道德價值的「領 會」（Erfassung）究竟是什麼性質？此一問題具有跨文化的普遍意義，因此上述的思考為我們之探討中、韓儒學中的相關問題提供了極有用的參考架構。在中國儒學的發展當中，本書選擇了南宋朱熹與湖湘學派關於「 仁」的辯論（第三章），以及晚明劉宗周對於孟子的「四端」與《中庸》的「喜怒哀樂」之獨特詮釋（第四、五章）為探討個案。在韓國儒學的發展當中，本書則選擇了朝鮮儒者李退溪與奇高峰、李栗谷與成牛溪關於「四端」與 「七情」的辯論（第六、七、八章）為探討個案。在這三個個案中，朱子學作為共同的參照系統，與康德後期的倫理學有類似之處，即均預設理性與情感（或性與情）二分的主體性架構。反之，張栻等湖湘學者、劉蕺山、李退溪 與成牛溪將孟子的「四端」或《中庸》的「喜怒哀樂」視為與「七情」異質的形上之情，此點與現象學倫理學的基本方向不謀而合.

In formal semantics based on modern type theories, some sentences may be interpreted as judgements and some as logical propositions. When interpreting composite sentences, one may want to turn a judgemental interpretation or an ill-typed semantic interpretation into a proposition in order to obtain an intended semantics. For instance, an incorrect judgement $$a:A$$ may be turned into its propositional form $$\textsc {is}(A,a)$$ and an ill-typed application p(a) into $$\textsc {do}(p,a)$$, so that the propositional forms can take part in logical compositions (...) that interpret composite sentences, especially those that involve negations and conditionals.In this paper, we propose an operator not that facilitates such a transformation. Introducing not axiomatically, with five axiomatic laws to govern its behaviour, we shall use it to define $$\textsc {is}$$ and $$\textsc {do}$$ and give examples to illustrate its use in semantic interpretation. The introduction of not into type theories is logically consistent – this is justified by showing that not can be defined by means of the heterogeneous equality $$\textrm{JMeq}$$ so that all of the axiomatic laws for not become provable. Therefore, since the extension with $$\textrm{JMeq}$$ preserves logical consistency, so does the extension with not. We shall also study conditions under which $$\textsc {is}$$ and $$\textsc {do}$$ operators can be used safely without the risk of over-generation. (shrink)

This study examines the educational policy related to the inclusion of ethnic minority population in the contemporary China. It has undergone three stages of the educational policy transformation, including the beginning, development and perfection stages. It is characterized by the steadiness, caution, rapidity, quality improvement, standardization and quality. Through implementing the educational policy of the inclusion of ethnic minority population, it has made retrogress and achievements, which has played a positive role in national integration, maintaining national unity and regional stability, (...) improving the academic level and cross-cultural ability of minority students, and sharing educational resources. However, in current China’s education context, the implementation of education policy is faced with some prominent problems, such as the marginalized educational identity, non-communicative education, relative separation of systems and serious cultural barriers, relative emphasis on explicit education. Therefore, it suggested to construct a new integrative and open ethnic education system, strengthen the consciousness of the united integrated education, and enhancing the bi-directionality of ethnic integration.

This study explores the type-based vocational education system from the perspective of China. General education and vocational education are equal types of education in status, but not based on different levels of education in China. Specifically, the connotation of vocational education as type-based education is mainly embodied in ‘three directions’. The outstanding problems of vocational education as a type-based education include ‘four aspects’. Vocational education as a type-based education reform path is considered as ‘four reforms’. We should strengthen management, improve (...) the comprehensive quality of vocational college students and make clear the direction and explore the new path of reform and development of vocational colleges. In addition, we need to optimize investment and make innovations in the system and mechanism of funding for China’s vocational education. (shrink)

As a special group of police officer, prison police have to endure more work stress and have significant work-family conflict, which may lead to more physical and mental health problems and need to be noticed by the society. The Work-Family Conflict Scale is a brief self-report scale that measures the conflict that an individual experiences between their work and family roles and the extent they interfere with one another. However, there is limited data on the scale’s psychometric properties. The aim (...) of this study was to examine the dimensionality and reliability of the Chinese version of the WFCS. The study sample was made up of a total of 717 Chinese prison police. The Rasch Rating Scale Model was used to determine the latent structure and estimate the quality of items and reliability of scale. The principle component analysis showed that the assumption of unidimensionality was fulfilled. The infit and outfit mean square statistics were of a reasonable range, and point-measure correlations indicted good model fit of each item. The item-person separation and reliability indices both met psychometric standards, illustrating good reliability. The person-item map indicated acceptable fit of items and persons, suggesting an alignment between persons and items. In addition, no evidence emerged of differential item functioning across different gender groups. Overall, the WFCS has good reliability and validity, and can be used to accurately evaluate the level of work-family conflict in Chinese prison police. (shrink)

This study aims to unpack policy evaluation and measurement of creating world-class universities in China from an integrated policy analysis. Specifically, an integrated policy analysis of policy evaluation of creating world-class universities concentrated on exploring the world class evaluation index released by the university rankings organization and the scholars’ views on the assessment criteria for world-class disciplines. The characteristics of policy evaluation of creating world-class (First-Class) universities included adhering to diversified comprehensive evaluation; clear educational objectives and positioning; taking students as (...) the foundation and cultivate first-class talents and paying attention to scientific research and produce first-class achievements. In the meanwhile, problems existing in the policy evaluation of creating world-class universities were also explored in this study. The suggestion and implications were offered to deepen theoretical research and enhance the practical effect of third-party evaluation and improve the evaluation system for "Double Tops" construction and balance the two characteristics of "Chinese characteristics" and "world-class" and respect the development rules of universities and disciplines and create a systematic ecology of orderly competition.

In recent years, more and more people are applying Convolutional Neural Networks to the study of sound signals. The main reason is the translational invariance of convolution in time and space. Thereby the diversity of the sound signal can be overcome. However, in terms of sound direction recognition, there are also problems such as a microphone matrix being too large, and feature selection. This paper proposes a sound direction recognition using a simulated human head with microphones at both ears. Theoretically, (...) the two microphones cannot distinguish the front and rear directions. However, we use the original data of the two channels as the input of the convolutional neural network, and the resolution effect can reach more than 0.9. For comparison, we also chose the delay feature (GCC) for sound direction recognition. Finally, we also conducted experiments that used probability distributions to identify more directions.

Post-stroke depression is a serious complication of stroke that significantly restricts rehabilitation. The use of immersive virtual reality for stroke survivors is promising. Herein, we investigated the effects of a novel immersive virtual reality training system on PSD and explored induced effective connectivity alterations in emotional networks using multivariate Granger causality analysis. Forty-four patients with PSD were equally allocated into an immersive-virtual reality group and a control group. In addition to their usual rehabilitation treatments, the participants in the immersive-virtual reality (...) group participated in an immersive-virtual reality rehabilitation program, while the patients in the control group received 2D virtual reality rehabilitation training. The Hamilton Depression Rating Scale, modified Barthel Index, and resting-state functional magnetic resonance imaging data were collected before and after a 4-week intervention. rsfMRI data were analyzed using multivariate GCA. We found that the immersive virtual reality training was more effective in improving depression in patients with PSD but had no statistically significant improvement in MBI scores compared to the control group. The GCA showed that the following causal connectivities were strengthened after immersive virtual reality training: from the amygdala, insula, middle temporal gyrus, and caudate nucleus to the dorsolateral prefrontal cortex; from the insula to the medial prefrontal cortex; and from the thalamus to the posterior superior temporal sulcus. These causal connectivities were weakened after treatment in the control group. Our results indicated the neurotherapeutic use of immersive virtual reality rehabilitation as an effective non-pharmacological intervention for PSD; the alteration of causal connectivity in emotional networks might constitute the neural mechanisms underlying immersive-virtual reality rehabilitation in PSD.

This study aimed to investigate the features of only child status related to physical health, mathematics achievement, and school feelings and expectations from a different perspective. A representative sample of 91,619 Grade 4 students with an average age of 10.4 ± 0.7, among which 28,631 were only children, were assessed. We used propensity score matching and the average treatment effects on the treatment to analyze data. The treatment was the only child of a family. The results indicated that only children (...) have better academic achievement and school feelings, while non-only children have better physical status and anaerobic fitness. In addition, gender and rural vs. urban areas differences were also explored. The adverse situation for rural only boys is emphasized for families, researchers, and governments to focus on. Some suggestions are given under the Two- and Three-Child Policy. (shrink)
