Previous studies have shown that the motion intention recognition for lower limb prosthesis mainly focused on the identification of performed gait. However, the bionic prosthesis needs to know the next movement at the beginning of a new gait, especially in complex operation environments. In this paper, an upcoming locomotion prediction scheme via multilevel classifier fusion was proposed for the complex operation. At first, two motion states, including steady state and transient state, were defined. Steady-state recognition was backtracking of a completed (...) gait, which would be used as prior knowledge of motion prediction. In steady-state recognition, surface electromyographic and inertial sensors were fused to improve recognition accuracy; five typical locomotion modes were recognized by random forest classifier with over 97.8% accuracy. The transient state was defined as an observation period at the initial stage of upcoming movement, in which only the sEMG signal was recorded due to the limitation of sliding window length. LightGBM classifier was validated to outperform other methods in the accuracy and prediction time of transient-state recognition. Finally, a simplified HMM model based on prior knowledge and observation result was constructed to predict upcoming locomotion. The results indicated that the locomotion prediction was over 91% accuracy. The proposed scheme implements the locomotion prediction at the initial stage of each gait and provides critical information for the gait control of lower limb prosthesis. (shrink)

In a congested large-scale subway network, the distribution of passenger flow in space-time dimension is very complex. Accurate estimation of passenger path choice is very important to understand the passenger flow distribution and even improve the operation service level. The availability of automated fare collection data, timetable, and network topology data opens up a new opportunity to study this topic based on multisource data. A probability model is proposed in this study to calculate the individual passenger’s path choice with multisource (...) data, in which the impact of the network time-varying state on passenger path choice is fully considered. First, according to the number and characteristics of OD candidate paths, the AFC data among special kinds of OD are selected to estimate the distribution of passengers’ walking time and waiting time of each platform. Then, based on the composition of path travel time, its real-time probability distribution is formulated with the distribution of walking time, waiting time, and in-vehicle time as parameters. Finally, a membership function is introduced to evaluate the dependence between passenger’s travel time and the real-time travel time distribution of each candidate path and take the path with the largest membership degree as passenger’s choice. Finally, a case study with Beijing Subway data is applied to verify the effectiveness of the model presented in this study. We have compared and analysed the path calculation results in which the time-varying characteristics of network state are considered or not. The results indicate that a passenger’s path choice behavior is affected by the network time-varying state, and our model can quantify the time-varying state and its impact on passenger path choice.

Circular economy is a critical approach to realize the coordinated development of society, economy, and ecological environment. Given the fact that urban is a complex system in which human beings integrate material, energy, information, and natural environment and interact and influence each other, reviewing the urban circular economy research and development could benefit for having a better and comprehensive understanding on urban complexity. Mainly based on the Chinese literature studies from 1999 to 2020, this study aims to present an in-depth (...) analysis of the research themes, policy systems, and index system of Chinaʼs urban-scale circular economy, discuss the changes and evolution trends of themes, levels, and perspectives in time series, sort out the policy systems at both the national and local levels, and analyze the design principles and application fields of indicators. Finally, we propose that future development of an urban circular economy should be built based on modern techniques, technologies, and models. The construction of development mechanism on the circular economy should be framed as “government-led, market-driven, legal norms, policy support, technological support, and public participation” and inject concepts such as “Internet +,” “sharing economy,” “Internet of Things,” and “artificial intelligence.”.

GraphicalPatients with early- to middle-stage PD were enrolled for C-Gait assessment and traditional walking ability assessments. The correlation of C-Gait assessment and traditional walking tests were studied. Two models were established based on C-Gait assessment and traditional walking tests to explore the value of C-Gait assessment in predicting freezing of gait.ObjectiveEfficient methods for assessing walking adaptability in individuals with Parkinson’s disease are urgently needed. Therefore, this study aimed to assess C-Gait for detecting freezing of gait in patients with early- to (...) middle-stage PD.MethodPeople with PD diagnosis were recruited from April 2019 to November 2019 in Beijing Rehabilitation Hospital. The participants performed six items of walking adaptability on an instrumented treadmill augmented with visual targets and obstacles. The patient’s walking adaptability was evaluated by C-Gait assessment and traditional walking tests, and FOG-related indexes were collected as outcome measures. Two discriminant models were established by stepwise discriminant analysis; area under the receiver operating characteristic curve was used to validate the models.ResultIn total, 53 patients were included in this study. Most C-Gait assessment items had no or low correlations with traditional walking tests. The obstacle avoidance and speed of adaptation items could lead to FOG with high sensitivity. In addition, the C-Gait assessment model had slightly better discrimination of freezers from non-freezers compared with traditional walking test models ; specifically, obstacle avoidance and speed of adaptation have uniquely discriminant potential.ConclusionC-gait assessment could provide additional value to the traditional walking tests for PD. Gait adaptability assessment, as measured by C-Gait, may be able to help identify freezers in a PD population. (shrink)

Rising negative emotions are like “time bombs” that impede productivity in the workplace. The present investigation provides an insight into the effects of defensive silence and defensive voice on counterproductive work behavior through knowledge hiding in the context of knowledge workers in Chinese academic institutions. Partial least square structural equation modeling was applied to the current samples. The study obtained conjecture the proposed mediating role of knowledge hiding between the negative working attitude and counterproductive work behavior, which is against the (...) organizational norms and performance. The result indicates that the positive relationships exist from defensive silence and defensive voice to counterproductive work behavior, mediated by knowledge hiding. This study links knowledge hiding literature and stimulus-organism-response to better explore the academic behavior in a knowledge setting. (shrink)

Artificial intelligence (AI) ethics is proposed as an emerging and interdisciplinary field concerned with addressing the ethical issues of AI, such as the issue of moral decision-making. The conflict between our intuitive moral judgments constitutes an inevitable obstacle to decision-making in AI ethics. This article outlines the Moral Relevance Approach, which could provide a considerable moral foundation for AI ethics. Taking moral relevance as the precondition of the consequentialist principles, the Moral Relevance Approach aims to plausibly consider individual moral claims. (...) It is not only the common ethical target shaping our moral consensus but also the inherent moral ability connecting others with us. (shrink)

Supporting families of people with developmental disabilities from culturally diverse backgrounds is receiving increased attention in the era of globalisation. However, there is little information about how disability policy and cultural values work together to support families. This article examined how disability policy and Chinese cultural values influence family care of children and young people with developmental disabilities. By comparing qualitative interview data from Chinese families in Taipei (15) and Sydney (10), we analysed how their expression of cultural values in (...) family care differs by policy context, relative to ethics of care claims for recognition, rights and redistribution. We found that positive expressions of Chinese culture in family care fade if policies do not complement them. Policies can alleviate potential tension with cultural values in three ways: reinforcing family capacity to care; ensuring the rights of both family caregivers and people with disabilities; and extending care choices for families. These approaches resonate with ethics of care principles. We argue that culturally responsive disability policy for families means working with cultural values to achieve ethics of care. This implies that incorporating principles of ethics of care could inform cultural responsiveness in disability policy development. (shrink)

Human resource management (HRM) is underpinned by, and contributes to, the business ethics of the organization. Opportunities available to men and women as managers, and the role of managers more broadly, are critical in shaping business ethics in contemporary organizations. Research on women in management therefore provides an important lens through which to understand the institutional and cultural context of HR ethics as part of the business ethics of a country. To date, women in management in China remains an under-charted (...) topic of research in the HRM field. Extant research and recommendations on the improvement of the position of women in management in China focus primarily on women themselves from a traditional, gender norm angle, instead of challenging the political and patriarchal system or any institutionalized discriminatory practice. This is, in part, due to the absence in China of a critical feminism approach or feminist movement, as found in Western societies, and the continuing strong influence of the state and media in portraying women’s (stereotypical) image. There is significant room for research capacity building in scholarship on women in management research, for example, and through cross-fertilization of different disciplines and more rigorous research design and execution. This paper provides a critical analysis of extant literature on women in management and the ideologies underpinning it, and offers some suggestions for future research and conceptualization.

This study examines the associations of constructivist beliefs and classroom climate on teachers' self-efficacy in instruction, classroom management, and student engagement among Australian secondary mathematics teachers. To do this, it uses the integrated model of teachers' self-efficacy with the concept of analysis of teaching tasks. The study uses structural equation modeling to analyze data from 495 mathematics teachers in the Teaching and Learning International Survey 2013. The results reveal the integrated model is a valid theoretical framework to explain Australian secondary (...) mathematics teachers' self-efficacy. Teachers' constructivist beliefs and classroom climate are positively and statistically significantly related to teachers' self-efficacy in instruction, classroom management and student engagement. In contrast, constructivist beliefs have no significant correlation with classroom climate. (shrink)

With the rapid development of technologies, online learning, especially email dialogue journaling, has been playing an increasingly important role in foreign language learning and teaching in recent years. While many studies have examined the effect of email learning on student learning performance, few have looked into students? attitudes towards email application and its impact on their learning outcomes. Positive user attitudes (high self?efficacy) have been considered critical factors that contribute to the subsequent and successful academic performance. By integrating email for (...) the reading learning process, this study developed an electronic?based peer collaborative environment to explore students? attitudes towards email application in reading classes. Specifically, the relationship between students? self?efficacy and their reading performance was examined. The results demonstrate that most students maintain positive attitudes towards the potential outcomes of email application on reading achievement. Furthermore, the feature of electronic discussion has a greater direct effect on the reading enhancement. Implications of certain designs of email tasks for an enhanced second language reading development are presented. (shrink)
