安倍内阁政策得失与日本政局走向

9月12日下午，安倍突然宣布辞去首相职务。由于事发突然，引发了日本政坛地震。安倍于8月27日刚改组完内阁，9月10日在临时国会上发表施政演说，9月12日下午预定接受国会质询，无人料到安倍会在发表施政演说后、接受各党党首质询前辞职。朝野在惊愕之余，纷纷批评安倍不负责任。安倍就任首相不到一年为何突然去职，其政策得失何在，未来日本政局将如何演变，无不引发人们对现代日本政治及社会变化的深思。     

Automated Classification of Epiphyses in the Distal Radius and Ulna using a Support Vector Machine

The aim of this study was to automatically classify epiphyses in the distal radius and ulna using a support vector machine (SVM) and to examine the accuracy of the epiphyseal growth grades generated by the support vector machine. X‐ray images of distal radii and ulnae were collected from 140 Chinese teenagers aged between 11.0 and 19.0 years. Epiphyseal growth of the two elements was classified into five grades. Features of each element were extracted using a histogram of oriented gradient (HOG), and models were established using support vector classification (SVC). The prediction results and the validity of the models were evaluated with a cross‐validation test and independent test for accuracy (P_A). Our findings suggest that this new technique for epiphyseal classification was successful and that an automated technique using an SVM is reliable and feasible, with a relative high accuracy for the models.     

Confessions in the Criminal Process

This article undertakes a theoretical exploration of the roles that confessions can play in the criminal process and of the importance that is placed on their voluntariness. It draws on contemporary and historical sources, as well as materials from different legal systems and traditions. Three possible perspectives on the topic are identified: the moral, the epistemic and the political. Adopting each of these perspectives in turn, I set out three distinct dimensions of confessions in the criminal process. In my account of each dimension, voluntariness is construed in the light of a particular understanding of confessions that is conceptually tied to a particular understanding of the criminal process. The conclusion remarks on the interplay of the three dimensions.     

Deep learning for sex determination: Analyzing over 200,000 panoramic radiographs

The objective of this study is to assess the performance of an innovative AI-powered tool for sex determination using panoramic radiographs (PR) and to explore factors affecting the performance of the convolutional neural network (CNN). The study involved 207,946 panoramic dental X-rays and their corresponding reports from 15 clinical centers in São Paulo, Brazil. The PRs were acquired with four different devices, and 58% of the patients were female. Data preprocessing included anonymizing the exams, extracting pertinent information from the reports, such as sex, age, type of dentition, and number of missing teeth, and organizing the data into a PostgreSQL database. Two neural network architectures, a standard CNN and a ResNet, were utilized for sex classification, with both undergoing hyperparameter tuning and cross-validation to ensure optimal performance. The CNN model achieved 95.02% accuracy in sex estimation, with image resolution being a significant influencing factor. The ResNet model attained over 86% accuracy in subjects older than 6 years and over 96% in those over 16 years. The algorithm performed better on female images, and the area under the curve (AUC) exceeded 96% for most age groups, except the youngest. Accuracy values were also assessed for different dentition types (deciduous, mixed, and permanent) and missing teeth. This study demonstrates the effectiveness of an AI-driven tool for sex determination using PR and emphasizes the role of image resolution, age, and sex in determining the algorithm's performance.     

A new perspective to explore the technology transfer efficiencies in US universities

Universities play a critical role in the complex technology transfer process that facilitates technology transformation from pure research activities to commercialization. The literature has recently focused on whether universities are efficient in this process. With a two-stage perspective, this study explores the required capabilities for universities to be efficient in technology transfer process. To explore the efficiencies in different stages of technology transfer, we apply a 2-stage process DEA method. The model considers 2 inputs, 2 intermediate variables, and 3 output variables from the Association of University Technology Management database. These variables represent funding resource, patenting activities, and licensing and entrepreneurships. Technology transfer in the 2-stage perspective includes the research innovation stage and the value creation stage. The results show that achieving efficiency in the 2 technology-transfer stages requires many different innovation capabilities; thus, most efficient universities only perform efficiently in one of the two stages. When mapping the relative site of universities in the reference network, we found that efficient universities in the research innovation stage are in a more centralized location than those in the value creation stage. By contrast, in the value creation stage, efficient universities can be identified as different reference groups for specific inefficient universities. The network visualization also helps to explain that universities must consider their relative advantages and capabilities to reach efficiency goals in different stages. The comparison between the large-scale group and the small-scale group also showed that a resource scale is critical for universities to accumulate different required capabilities for efficiencies in both stages.     

Uncertain allies or uncomfortable neighbors? Making sense of China–North Korea Relations, 1949–2010

Abstract

This study is based upon two premises: (1) the available literature, though voluminous, fails to provide systematic understandings of the complex and evolving relations between China and North Korea; and (2) China and North Korea had been short of being trusted allies bound in blood and belief even before the launch of post-Mao reforms and the normalization of Beijing–Seoul relations. This article dissects this curious relationship into four questions: (1) What does history inform us about China's relations with (North) Korea? (2) Has China communicated effectively with North Korea? (3) Have China and North Korea been ‘trusted allies’? (4) How effective has China been in inducing North Korea to comply with its demands over the years? The authors argue that, geo-strategically, China can hardly afford to put North Korea in an adversarial position. Furthermore, residues of the Factional Incident of 1956 and North Korea's deep-rooted suspicion of China still linger on. These have been the sources of Beijing's dilemma in consistently opting for ‘soft’ measures despite that North Korea's provocative acts and nuclear weapons programs have negatively affected China's interests. From the outset, China and North Korea had been more uncertain allies who had to cooperate with each other under the ideological and geopolitical imperatives of the difficult times. The authors also suggest that it would be misleading to put Sino–North Korean dynamics in a usual category of big power–small nation relations where power asymmetry generally works against the latter. North Korea has undoubtedly been an atypical ‘small nation’. It is due to these limitations that China's pressurizing has not been always effective and that Beijing's reactions have been continuously cyclical. This cyclical trend is not likely to be broken since the upcoming drama of Sino–American rivalry is bound to close the window of such opportunities for China, which will nevertheless regard North Korea increasingly as a liability, if not uncomfortable neighbor.     

Singapore's cultural policy and its consequences

Abstract

This article explores the effects of Singapore's Global City for the Arts project on the local theater industry. It begins by describing the character of the Singapore state and its ability to meet the challenges of globalization. It then shows that while historically global in orientation, the city-state's early cultural policies were resolutely local and insular prior to the economic recession in 1985. From that year on, local arts and culture was driven by an economic rationale — eventually culminating in the birth of a globally oriented national cultural policy: the Global City for the Arts project. The author contends that the Global City for the Arts project has pressured the Singapore state into shedding some of its authoritarian practices in order to conform to international norms. However, the author also illustrates how certain theater companies with the requisite cultural capital for the Global City for the Arts project have benefited from the country's cultural policies while others that do not possess such cultural capital are marginalized. The article concludes by arguing that the Singapore state, in going global, exacerbates the economic disparity by accentuating preexisting inequalities and divisions in the local.     

From Resistance to Accommodation: Taiwanese Working Class in the Early Postwar Era (1945–55)

This article explores Taiwan’s worker activism in the early postwar era (1945–55) in the attempt to revise the received perception of labour quiescence under high authoritarianism. Rather than a passive victim of state repression, workers mounted two rounds of resistance, first in the form of factory-defending worker-militias during the February 28 Incident of 1947 and later in the subsequent clandestine communist movement. With the case of sugar industry workers, it is argued the postwar ethnic domination was the triggering factor for worker resistance, which was severely repressed. Their consecutive failures as well as the lure of the privileged status of state-owned enterprise employees eventually persuaded them to accept a subordinate role.     

Rangeland Degradation in North China Revisited? A Preliminary Statistical Analysis to Validate Non-Equilibrium Range Ecology

Over the past decades, the concepts of carrying capacity and Clementsian vegetation succession have come under attack from the theory of Non-Equilibrium Range Ecology. The new theory hypothesises that in arid regions with high rainfall variability the ecology is mainly determined by climatic and not biotic factors, such as animal grazing. The argument carried further implies that 'rangeland degradation' or 'desertification' are not caused by overgrazing but are part of a natural process of vegetation decline and growth in response to rainfall, which ruminant numbers merely follow. Few empirical studies involving time-series data have been executed to substantiate Non-Equilibrium Range Ecology. This article, hopes to make a contribution to the current debate with a statistical validation of one of its main postulates: the correlation between ruminant numbers and rainfall. The analysis is conducted with figures from the People's Republic of China: a state in which rangeland policy is an outstanding example of management on the basis of carrying capacities and Clementsian succession theory.
