Using firm-level data from the U.S. manufacturing industry, this paper examines the relationship among inventory leanness, structural strategies for supply chains, and the carbon intensities of a firm and its suppliers. We formulate hypotheses on and empirically test whether this internal characteristic and these two structural strategies can influence the intensities of firm-level and supply chain environmental impacts. We examine inventory leanness because it not only reflects a manufacturer’s operational efficiency but also markedly influences manufacturers’ financial performance. We also focus (...) on two closely related structural strategies that can influence the scope and ownership of the supply chain process, resulting in changes in emission allocation and, more importantly, how resources are utilized and shared in a firm. Based on multi-year carbon inventory data from U.S. manufacturing firms, we find that manufacturers with greater inventory leanness and a parsimonious process structure tend to attain lower firm-level and supply chain carbon intensities.

Background Individual physicians and physician-associated factors may influence patients’/surrogates’ autonomous decision-making, thus influencing the practice of do-not-resuscitate orders. The objective of this study was to examine the influence of individual attending physicians on signing a DNR order. Methods This study was conducted in closed model, surgical intensive care units in a university-affiliated teaching hospital located in Northern Taiwan. The medical records of patients, admitted to the surgical intensive care units for the first time between June 1, 2011 and December 31, (...) 2013 were reviewed and data collected. We used Kaplan–Meier survival curves with log-rank test and multivariate Cox proportional hazards models to compare the time from surgical intensive care unit admission to do-not-resuscitate orders written for patients for each individual physician. The outcome variable was the time from surgical ICU admission to signing a DNR order. Results We found that each individual attending physician’s likelihood of signing do-not-resuscitate orders for their patients was significantly different from each other. Some attending physicians were more likely to write do-not-resuscitate orders for their patients, and other attending physicians were less likely to do so. Conclusion Our study reported that individual attending physicians had influence on patients’/surrogates’ do-not-resuscitate decision-making. Future studies may be focused on examining the reasons associated with the difference of each individual physician in the likelihood of signing a do-not-resuscitate order. (shrink)

Editor's AbstractThis essay presents Mainland New Confucianism (MNC) as diverse but distinctive, as still in a process of maturation but already with a clear direction. According to Chen, MNC is a rejection of the twin modernist narratives of the left (revolution) and the right (enlightenment) in favor of a narrative that downplays the ruptures associated with the May Fourth Movement and instead seeks to reconnect to China's past values and traditions.

The scholarship of Confucianism in China is in the process of restoration. Its historical missions are two-fold. It should preserve Chinese national characters and promote China’s modernization. These objectives are partly in conflict with each other. To realize the former objective, it is necessary to stress a historical continuity and consistency, to re-examine and justify the preservation of classical Confucian ideas and values in order to provide spiritual support for Chinese cultural identity and social cohesion. As to the latter objective, (...) it is necessary to reinterpret some part of the classical ideas and values and link them with the modern values such as liberty, justice and democracy. This essay analyzes the position of three Confucianist scholars, Jiang Qing, Chen Ming and Kang Xiaoguang, to show the different balances between conservatism and reformers when their writings confront the challenges of modernization and globalization.

Reinterpretation of our data concerning sleep onset, motivated by the desire to pay close attention to “intra-individual regularities,” suggests that the experience of control might be a key factor in determining the subjective sense that sleep has begun. This loss of control seems akin to what Frith and others have described as “passivity experiences,” which also occur in schizophrenia. Although clearly sleep onset is not a schizophrenic episode, this similarity might help to explain other features of sleep onset. We further (...) speculate that we could build upon the discovery of various “intra-individual regularities” to construct a model of sleep onset and other forms of sleep mentation. (shrink)

This study views the dispute over ‘996’ work schedule (i.e. working from 9 am to 9 pm, six days a week) as a critical discursive moment in the modernization and marketization of China. It argues that behind the dispute lies the hegemonic struggles between business tycoons and the government amidst China's changing business mode. Drawing on the theories of critical discourse analysis, recontextualization, hegemony and interdiscursivity, this study examines the (de)legitimation of ‘996’ by business tycoons and official news media through (...) the appropriation of different discourses to illuminate the hegemonic struggles behind recontextualizing ‘996’. It concludes that when the business tycoons are blatant enough to whitewash overwork as a ‘blessing’, the age-old curse in China starts to befall them. (shrink)

The RecA family proteins mediate homologous recombination, a ubiquitous mechanism for repairing DNA double‐strand breaks (DSBs) and stalled replication forks. Members of this family include bacterial RecA, archaeal RadA and Rad51, and eukaryotic Rad51 and Dmc1. These proteins bind to single‐stranded DNA at a DSB site to form a presynaptic nucleoprotein filament, align this presynaptic filament with homologous sequences in another double‐stranded DNA segment, promote DNA strand exchange and then dissociate. It was generally accepted that RecA family proteins function throughout (...) their catalytic cycles as right‐handed helical filaments with six protomers per helical turn. However, we recently reported that archaeal RadA proteins can also form an extended right‐handed filament with three monomers per helical turn and a left‐handed protein filament with four monomers per helical turn. Subsequent structural and functional analyses suggest that RecA family protein filaments, similar to the F1‐ATPase rotary motor, perform ATP‐dependent clockwise axial rotation during their catalytic cycles. This new hypothesis has opened a new avenue for understanding the molecular mechanism of RecA family proteins in homologous recombination. BioEssays 30:48–56, 2008. © 2007 Wiley Periodicals, Inc.

Modern education attaches great importance to interdisciplinary skills, among which computational thinking is a core element, and heralds a new era. IT application has shaped education in the 21st century. Computational thinking has provided further impetus for building an all-encompassing social network and fostering a DIY culture enabled by digital technologies. One empirical study used four apps to test children's development in computational thinking and fluency. The article will help students overcome their fears of coding. Peer reviews provide students with (...) an opportunity to learn from each other and become more motivated. These reviews also serve as feedback for teachers to evaluate students' performance. Experimental design is used in this study, and a peer review system is implemented. Freshmen attending a programming class in a university are used as samples. At the class, students write computer programs with f-Chart, which provides a graphical user interface for students to learn programming logic and design. Zuvio, a cloud-based interactive response system, is used to conduct the peer reviews. The data of this study are analyzed through R. The results show not only an improvement in students' learning performance but also a gap between students' peer review scores and teachers' evaluation scores. Learning feedback and evaluation is crucial to transform education between students and teachers into a sustainable cycle system. (shrink)

The high turnover of nurses has become a global problem. Several studies have proposed that nurses' perceptions of the ethical climate of their organization are related to higher job satisfaction and organizational commitment, and thus lead to lower turnover. However, there is limited empirical evidence supporting a relationship between different types of ethical climate within organizations and facets of job satisfaction. Furthermore, no published studies have investigated the impact of different types of ethical climate on the three components of organizational (...) commitment. This study attempts to explore the different types of ethical climate that exist in hospitals, and the degree of job satisfaction and organizational commitment of nurses in Taiwan. It uses path analysis to understand which types of ethical climate influence different facets of job satisfaction. The study also examines the impact of different types of ethical climate and facets of job satisfaction on the three components of organizational commitment. Questionnaires were distributed to 352 nurses. The relationships among variables were assessed by factor analysis, reliability, descriptive statistics, correlations, and regression. The important conclusion is that hospitals can increase job satisfaction and organizational commitment by influencing an organization's ethical climate. Hospital administrators can foster within organizations the climate types of caring, independent, and rules climate that increase satisfaction, while preventing organizations from developing the type of instrumental climate that decreases it.

To reveal the mechanisms of firms’ technological strategic choices between innovation and imitation, an evolutionary game model is proposed from the perspective of the behavioral biases. First, behavioral biases such as reference point dependence, loss aversion, and probability weighting can be defined and modeled based on the prospect theory. Second, according to the firm theory, a Cournot or Stackelberg game modeled with a technology spillover effect and intellectual property protection is applied to portray the interaction between firms. Third, an improved (...) evolutionary game model is provided by incorporating behavioral biases into the framework of the decision-making process. Finally, the simulation analysis of some important factors, such as intellectual property protection, patent fees, innovation risks, decision-making attitudes, and consumers’ price preference on firms’ technological strategic choices, is presented. The corresponding results show that innovation risk is an important factor affecting the technological strategic choices of firms, increasing the intellectual property protection and the patent fee for technology transfer can effectively control the spillover effect of technology, there is a partial U-shaped relationship between the consumers’ price preference and innovation, and the behavioral biases such as reference point dependence, loss aversion, and probability weighting will change the perception of payoff and risk and will eventually induce firms to adopt the innovation strategy.

IntroductionTranscranial direct current stimulation is a noninvasive brain stimulation technique that applied to modulate brain activity and enhance motor recovery. However, the neurobiological substrates underlying the effects of tDCS on brain function remain poorly understood. This study aimed to investigate the central mechanisms of tDCS on improving the athletic performance of male rowing athletes.MethodsTwelve right-handed male professional rowing athletes received tDCS over the left primary motor cortex while undergoing regular training. The resting-state functional magnetic resonance imaging data were acquired before (...) and after tDCS. Measures of amplitude of low-frequency fluctuation and regional homogeneity were calculated and compared between baseline and follow-up, as well as topological measures including global and local efficiency of functional brain networks constructed by graph theoretical analysis.ResultsMale rowing athletes showed increased isokinetic muscle strength of the left knee and left shoulder after tDCS. Increased ALFF values were found in the right precentral gyrus of male rowing athletes after tDCS when compared with those before tDCS. In addition, male rowing athletes showed increased ReHo values in the left paracentral lobule following tDCS. Moreover, increased nodal global efficiency was identified in the left inferior frontal gyrus of male rowing athletes after tDCS.ConclusionThe findings suggested that simultaneous tDCS-induced excitation over the primary motor cortex might potentially improve the overall athletic performance in male rowing athletes through the right precentral gyrus and left paracentral lobule, as well as left inferior frontal gyrus.

ObjectivesAcupuncture therapy has been used for cognitive impairment-related diseases, however, there are still few studies on the overall trend of acupuncture therapy on cognitive impairment based on bibliometric analysis. The purpose of this study was to explore the research trend of the impact of acupuncture on cognitive impairment in the past 15 years, analyze the research trends and hotspots, and provide new ideas and theoretical basis for future research directions.MethodsFrom the Web of Science Core Collection, the relevant literature on the (...) treatment of cognitive impairment with acupuncture from 2007 to 2022 was retrieved. Then, based on the CiteSpace and VOSviewer software of the Java platform, the cooperation between countries and institutions in this field, the co-citation of journals and documents, and the cooperation between authors and authors, etc. were analyzed. In addition, the co-occurrence and burst analysis of keywords are also carried out, and a visual knowledge map is drawn.ResultsAs of August 08, 2022, a total of 394 records related to the treatment of cognitive impairment with acupuncture were identified. The analysis results show: The number and rate of annual publications have steadily increased, with some fluctuations from year to year. The countries that contribute the most to this field are China and the USA. Among them, Beijing University of Chinese Medicine and Capital Medical University are tied for first place in terms of the number of published papers. Tao Jing is the most prolific author and the number one cited author.ConclusionsThe number of publications on acupuncture for cognitive impairment is expected to increase rapidly in future research, suggesting a bright future for the field. Future research hotspots will focus on pain, injury, protocol, diagnosis, guidelines, etc. It is also necessary to strengthen cross-regional and cross-country cooperation among various academic groups.

The rapid development of the Internet has granted college students easy access to vast amount of online resources, and to some degree has increased the chances of plagiarism problems. A number of studies have suggested that both faculty’s and students’ perceptions toward plagiarism are found to be influential on students’ plagiarizing behaviors, and limited research has been done to explore the perceptional differences between these two roles. This study aims to respond to the growing educational concerns about plagiarism by comparing (...) the perceptions held by faculty and college students. A total of 229 faculty and 634 college students in Taiwan completed the Perceptions of Student Plagiarism Questionnaire designed for the study. The results reveal that faculty held stricter standards than those of students. Results also indicate various causes of plagiarism, such as no interest in the learning subjects, lack of citation knowledge, or lack of research ability. Furthermore, significant disciplinary differences were shown to contribute to students’ plagiarism perception; the results reveal that most students with an Arts or Communication major held a relatively adverse thinking toward plagiarism. Last, this study provides research-based strategies for school and faculty to reduce the likelihood of plagiarism. (shrink)

Moral issues have been included in the studies of consumer misbehavior research, but little is known about the joint moderating effect of moral intensity and moral judgment on the consumer’s use intention of pirated software. This study aims to understand the consumer’s use intention of pirated software in Taiwan based on the theory of planned behavior (TPB) proposed by Ajzen (Organizational Behavior and Human Decision Processes, 50, 179, 1991). In addition, moral intensity and moral judgment are adopted as a joint (...) moderator to examine their combined influence on the proposed research framework. The results obtained from this Taiwan case reveal that the antecedent constructs proposed in the TPB model–an individual’s attitude and subjective norms toward using pirated software, and perceived behavioral control to use pirated software–indeed have positive impacts on the consumer’s use intention of pirated software. In addition, the joint moderating effect of moral intensity and moral judgment is manifested in the consumer’s use intention of pirated software. The results of this study not only could substantiate the results of consumer misbehavior research, but also could provide some managerial suggestions for Taiwanese government authorities concerned and the related software industries devoted to fighting pirated software.

ABSTRACT Between April 1820 and April 1822, stimulated by the restoration of the Cádiz Constitution, Bentham devoted himself to writing a number of works on the constitutional reform and colonial rule of Spain, which have been sources of a scholarly debate over Bentham's views on colony. By examining those works, this essay aims to supplement the scholarly debate by drawing attention to a thesis that Bentham developed in his criticism and evaluation of the Cádiz Constitution: a thesis concerning the irreconcilable (...) incompatibilities of liberal constitution and colonisation. I focus on Bentham's critical analyses of the Constitution, and indicate that Spain's colonial rule of Ultramaria not only intensified the weaknesses of the Constitution, but also rendered its merits useless, if not harmful, to the public in both hemispheres. Moreover, I explore the tension that Bentham detected between liberal constitutionalism and colonialism. I maintain that, in Bentham's observation, the civil rights granted by the Cádiz Constitution to the Ultramarians stood to facilitate the enlightenment of citizens and the formation of civil society. As a consequence, the delusion of the Spanish ruling few would be exposed, and the Ultramarians’ discontent with exploitation by such foreign rulers would sow the seeds of disobedience and resistance.

A variant of realizability for Heyting arithmetic which validates Church’s thesis with uniqueness condition, but not the general form of Church’s thesis, was introduced by Lifschitz (Proc Am Math Soc 73:101–106, 1979). A Lifschitz counterpart to Kleene’s realizability for functions (in Baire space) was developed by van Oosten (J Symb Log 55:805–821, 1990). In that paper he also extended Lifschitz’ realizability to second order arithmetic. The objective here is to extend it to full intuitionistic Zermelo–Fraenkel set theory, IZF. The machinery (...) would also work for extensions of IZF with large set axioms. In addition to separating Church’s thesis with uniqueness condition from its general form in intuitionistic set theory, we also obtain several interesting corollaries. The interpretation repudiates a weak form of countable choice, ACω,ω, asserting that a countable family of inhabited sets of natural numbers has a choice function. ACω,ω is validated by ordinary Kleene realizability and is of course provable in ZF. On the other hand, a pivotal consequence of ACω,ω, namely that the sets of Cauchy reals and Dedekind reals are isomorphic, remains valid in this interpretation. Another interesting aspect of this realizability is that it validates the lesser limited principle of omniscience. (shrink)

An increasing number of users have been attracted by location-based social networks in recent years. Meanwhile, user-generated content in online LBSNs like spatial, temporal, and social information provides an ever-increasing chance to study the human behavior movement from their spatiotemporal mobility patterns and spawns a large number of location-based applications. For instance, one of such applications is to produce personalized point of interest recommendations that users are interested in. Different from traditional recommendation methods, the recommendations in LBSNs come with two (...) vital dimensions, namely, geographical and temporal. However, previously proposed methods do not adequately explore geographical influence and temporal influence. Therefore, fusing geographical and temporal influences for better recommendation accuracy in LBSNs remains potential. In this work, our aim is to generate a top recommendation list of POIs for a target user. Specially, we explore how to produce the POI recommendation by leveraging spatiotemporal information. In order to exploit both geographical and temporal influences, we first design a probabilistic method to initially detect users’ spatial orientation by analyzing visibility weights of POIs which are visited by them. Second, we perform collaborative filtering by detecting users’ temporal preferences. At last, for making the POI recommendation, we combine the aforementioned two approaches, that is, integrating the spatial and temporal influences, to construct a unified framework. Our experimental results on two real-world datasets indicate that our proposed method outperforms the current state-of-the-art POI recommendation approaches. (shrink)

Amid the social background of China where the Internet has penetrated into every corner of an adolescent’s life, we were concerned of the role of Internet usage in influencing the educational gap among social classes. We investigated the mediating role of Internet usage preference for entertainment in the relationship between the family socioeconomic status and the adolescent’s academic achievement and explored the moderating role of future orientation in the relationship. A total of 614 junior high school students were recruited to (...) complete a questionnaire survey, including questionnaires for family SES, Internet usage preference, and adolescent future orientation. The results showed that the relationship between family SES and academic achievement was mediated by Internet usage preference for entertainment; the indirect effect was moderated by future orientation, such that the negative association between family SES and Internet usage preference for entertainment was only indicated in adolescents with low future orientation; and the direct association between family SES and Internet usage preference for entertainment was moderated by future orientation.

To understand the ethical issue of gender inequality in entrepreneurial financing, we examine the effect of angel investors’ political ideology, the conservatism–liberalism continuum, on their investments in women-owned ventures. We propose that more conservative angel investors tend to have a lower percentage of investments in women-owned ventures in their portfolios. Moreover, drawing on the gender role congruity theory, we show that when investing in women-owned ventures, more conservative angels favor women-owned ventures with a higher percentage of male co-founders and operating (...) in women-dominated industries. Our analysis, based on a longitudinal sample of 172 angels from 2010 to 2019, supports these hypotheses. Our study contributes to the literature by highlighting angel political ideology as a critical antecedent of the gender disparity in entrepreneurial financing. (shrink)

This study proposed a children’s digital art ability training system with artificial intelligence-assisted learning, which was designed to achieve the goal of improving children’s drawing ability. AI technology was introduced for outline recognition, hue color matching, and color ratio calculation to machine train students’ cognition of chromatics, and smart glasses were used to view actual augmented reality paintings to enhance the effectiveness of improving elementary school students’ imagination and painting performance through the diversified stimulation of colors. This study adopted the (...) quasi-experimental research method and designs the pre-test and post-test for different groups. The research subjects are the Grade 4 students of an elementary school in Taitung City, Taiwan. The test tools included an imagination test and an evaluation of painting performance ability. The test results of a total of 30 students before and after the experiment included the experimental group that received the children’s digital art ability training system with AI-assisted learning and 30 students in the control group that had not received the teaching were analyzed by covariance. These results were supplemented by the description and interpretation of student feedback, teachers’ reflection notes, and other qualitative data to understand the performance of the students in the experimental group in terms of imagination and painting performance.

This article attempts to strip away the Eurocentrism of the Enlightenment, to reconsider how this concept that originated in Europe was transmitted to China. This is thus an attempt to treat the Enlightenment in terms of its global, worldwide significance. Coming from this perspective, the Enlightenment can be viewed as a history of the exchange and interweaving of concepts, a history of translation and quotation, and thus a history of the joint production of knowledge. We must reconsider the dimensions of (...) both time and space in examining the global Enlightenment project. As a concept, the Enlightenment for the most part has been molded by historical actors acting in local circumstances. It is not a concept shaped and brought into being solely from textual sources originating in Europe. As a concept, the Enlightenment enabled historical actors in specific localities to begin to engage in globalized thinking, and to find a place for their individual circumstances within the global setting. This article follows such a line of thought, to discuss the conceptual history of the Enlightenment in China, giving special emphasis to the processes of formation and translation of this concept within the overall flow of modern Chinese history.

Working memory performance affects children’s learning. This study examined objective, subjective, and physiological cognitive load while children completed a spatial working memory complex span task. Frist, 80 Taiwanese 11-year-olds who participated in Experiment 1 confirmed the suitability of the materials. Then, 72 Taiwanese 11-year-olds were assigned to high and low complexity groups to participate in Experiment 2 to test the study hypothesis. Children had to recall at the end of a dual-task list and answer two questions regarding the difficulty and (...) mental effort involved in processing and storage. Their pupil diameters were recorded using an eye-tracker. Two-way mixed ANOVA found that the processing requirements and memory load reduced storage and aggravated the subjective CL of storage; the subjective CL of processing was higher under highly complex conditions. Stepwise regression analysis indicated that subjective CL of processing predicted memory performance in low CL conditions, and physiological CL of processing predicted it in high CL conditions.

Electric-mechanical equipment manufacturing industries focus on the implementation of intelligent manufacturing systems in order to enhance customer services for highly customized machines with high-profit margins such as electric power transformers. Intelligent manufacturing consists in using supply chain data that are integrated for smart decision making during the production life cycle. This research, in cooperation with a large electric power transformer manufacturer, provides an overview of critical intelligent manufacturing technologies. An ontology schema forms the terminology relationships needed to build two intelligent (...) supply chain management modules for the IM system demonstration. The two core modules proposed in this research are the intelligent supplier selection and component ordering module and the product quality prediction module. The intelligent supplier selection and component ordering module dispatches orders that match the best options of suppliers based on combined analytic hierarchy process analysis and multiobjective integer optimization. In the case study, the intelligent supplier selection and component ordering module demonstrates several acceptable Pareto solutions based on strict constraints, which is a very challenging task for decision makers without assistance. The second module is the product quality prediction module which uses multivariate regression and ARIMA to predict the quality of the finished products. Results show that the R square values are very close to 1. The module shortens the time for the company to accurately judge whether the two semifinished iron cores for the product meet the quality requirements. The component supplier selection module and the finished product quality prediction module developed in this research can be extended to other IM systems for general high-end equipment manufacturers using mass customization.

In this study, the under-examined area of privacy perception and protection on Chinese social media is investigated. The prevalence of digital technology shapes the social, political and cultural aspects of the lives of urban young adults. The influential Chinese social media platform WeChat is taken as a case study, and the ease of connection, communication and transaction combined with issues of commercialisation and surveillance are discussed in the framework of the privacy paradox. Protective behaviour and tactics are examined through different (...) perceptions of privacy in the digital age. The findings of this study suggest that users possess certain amount of freedoms on WeChat. However, users’ individual privacy attitudes and behaviour in practice suggest they have a declined sense of their own freedom and right to privacy. A privacy paradox exists when users, while holding a high level of concerns, in reality do little to further the protection of their personal information on WeChat. We argue that once a user has ingrained part of their social engagement within the WeChat system, the incentive for them to remain a part of the system outweighs their requirement to secure their privacy online as their decision-making is largely based on a simple cost-benefit analysis. The power and social capital yielded via WeChat is too valuable to give up as WeChat is widely used not only for private conversations, but also for study or work-related purposes. It further blurs the boundaries between the public, the professional and the private, which is a rather unique case compared with other social media around the world. (shrink)

To improve the spatial resolution of imaging and get more effective brain function information, a multi-distance probe configuration with three distances and 52 channels is designed. At the same time, a data conversion method of modified Beer–Lambert law with partial pathlength is proposed. In the experiment, three kinds of tasks, grip of left hand, grip of right hand, and rest, are performed with eight healthy subjects. First, with a typical single-distance probe configuration, the feasibility of the proposed MBLL with PPL (...) is preliminarily validated. Further, the characteristic of the proposed method is evaluated with the multi-distance probe configuration. Compared with MBLL with differential pathlength factor, the proposed MBLL with PPL is able to acquire more obvious concentration change and can achieve higher classification accuracy of the three tasks. Then, with the proposed method, the performance of the multi-distance probe configuration is discussed. Results show that, compared with a single distance, the combination of the three distances has better spatial resolution and could explore more accurate brain activation information. Besides, the classification accuracy of the three tasks obtained with the combination of three distances is higher than that of any combination of two distances. Also, with the combination of the three distances, the two-class classification between different tasks is carried out. Both theory and experimental results demonstrate that, using multi-distance probe configuration and the MBLL with PPL method, the performance of brain function detected by NIRS can be improved.
