ObjectiveTo investigate the instant impact of hemodialysis on the cerebral morphological measurements of patients with end-stage renal disease.Materials and methodsTwenty-five patients undergoing maintenance HD and twenty-eight age-, sex-, and education-matched healthy control were included. The HD group and HC group had 3D high-resolution structural magnetic resonance imaging scans twice and once, respectively. Both groups underwent neuropsychologic tests. The morphological measurements of structural MRI were measured using CAT12 and these measures were compared among three groups. The relationship between morphological measures and (...) clinical parameters and neuropsychological tests were investigated through multiple regression analysis.ResultsCompared to the HC group, the cortical thickness before HD significantly decreased in the bilateral temporal lobe and significantly decreased in the left superior temporal gyrus after HD. The cortical thickness significantly increased in the bilateral temporal lobe, frontal lobe and occipital lobe after HD compared to before HD. The sulcus depth in the bilateral insula, frontal lobe, and parietal lobe after HD significantly increased compared to before HD. No significant differences in sulcus depth between HD and HC were detected. After HD, the cortical thickness of the right parsopercularis was positively correlated with the number connection test-A. Cortical thickness in multiple regions were positively correlated with blood flow velocity and cortical thickness in the left parahippocampal gyrus was negatively correlated with ultrafiltration volume. Patients showed better performance in the digit symbol test and line tracing test after HD compared to before HD, but there were no significant differences in the comparison of neuropsychologic tests between patients and HC.ConclusionThe instant morphological changes were captured during a single hemodialysis in HD patients. There was an association between these instant changes in the brain and clinical parameters and neuropsychologic tests. This work implied the instant impact of a single hemodialysis impact on the brain in HD patients. (shrink)

The adaptive object model method is an effective way to develop dynamic and configurable adaptive software. It has the characteristics of metamodel, description drive, and runtime reflection. First, the core idea of the adaptive object model is explained; then, the five modes of establishing the metamodel in the adaptive object model architecture, the model engine, and supporting tools are analyzed; and the basketball tracking algorithm of the adaptive object model is discussed. Secondly, a two-dimensional joint information strategy is proposed to (...) improve the tracking effect. When the basketball is in a very complex environment, there will always be some color information in the background that is the same as the target, which affects the effect of basketball tracking. Therefore, this paper proposes a Camshift tracking method based on the significance of histograms, through real time. The basketball movement is compared with the background histogram to continuously adjust the basketball movement tracking model. These two methods can better establish the tracking model of the basketball adaptive object, reduce the interference of background information, and achieve the effect of stable tracking of the target. The simulation experiment results show that the method proposed in this paper can effectively improve the accuracy of the basketball goal model and achieve stable tracking of the goal. (shrink)

Based on work-family border theory and work-home resource theory, this paper examines the impact of border keeper’s support on work-family enrichment and whether or how work-family boundary flexibility mediates the relationship between border keeper’s support and work-family enrichment. A sample of 504 preschool teachers in Guangdong province, China completed questionnaires. The research results show a two-way process of work-family enrichment for preschool teachers in China. Organizational support was directly and significantly correlated with work-to-family enrichment, and family support was significantly and (...) directly correlated with family-to-work enrichment. Organizational support had no significant positive predictive effect on work boundary flexibility which has a significant positive predictive effect on WFE. Family support had a significant positive predictive effect on family boundary flexibility which had a significant positive predictive effect on the FWE. In addition, the study found that family boundary flexibility mediates the relationships between family support and FWE whereas work boundary flexibility did not mediate the relationships between organizational support and WFE. The above research results are partly consistent with the existing research, and partly inconsistent, which is related to the profound influence of traditional culture in Chinese society and the current situation of preschool teachers in China. Such findings have important implications for improving the work-family enrichment of preschool teachers. (shrink)

Cross-shareholding is a new type of strategic means for capital operation and is an important component of corporate governance. With the increasing complexity of business motivation, the structure of a cross-shareholding network is becoming more intricate, and it exposes various important local patterns with different economic functions. The goal of this paper is to uncover investment mechanisms and economic functions implied in cross-shareholding networks by analyzing the local characteristic patterns of company interactions. In this paper, we construct the CSNs of (...) listed companies and extract the directed triadic motifs to reveal the evolutionary characteristics of local investment patterns at the company and industry levels. On the company level, we find that companies tend to form V-shaped structures with other companies, but bidirectional shareholding patterns and circular relationships in the triads are scarce. On the industry level, we identify the characteristic linking patterns of some industries with a role analysis of the industries. Furthermore, we detect the evolutionary characteristics of industry interrelationships in three implied patterns. Such a motif evolution analysis may provide valuable information for investors and supervisory departments that make decisions about investment portfolios and policy. Meanwhile, this study is also helpful for exploring the implied information in other empirical networks. (shrink)

Longitudinal diagnostic classification models (DCMs) with hierarchical attributes can characterize learning trajectories in terms of the transition between attribute profiles for formative assessment. A longitudinal DCM for hierarchical attributes was proposed by imposing model constraints on the transition DCM. To facilitate the applications of longitudinal DCMs, this paper explored the critical topic of the Q-matrix design with a simulation study. The results suggest that including the transpose of the R-matrix in the Q-matrix improved the classification accuracy; ten-item tests measuring three (...) linear attributes across three time points provided satisfactory classification accuracy for low-stakes assessment. Educational implications and future directions were discussed. (shrink)

The coronavirus disease 2019 pandemic caused by severe acute respiratory syndrome coronavirus 2 is challenging the dental community to an unprecedented degree. Knowledge of the increased risk of infection in dental settings has been disseminated to the public and guidelines have been formulated to assist dental attendance decision-making. However, dental attendance behaviors incompatible with treatment need is not uncommon in clinical settings. Important gaps remain in the knowledge about how psychological factors are affecting dental attendance behaviors during the COVID-19 epidemic. (...) In this cross-sectional study, a questionnaire survey was performed during February and March 2020. A total of 342 and 294 dental patients who attended and avoided dental visits, respectively, were included. The participants were classified into four groups based on dental attendance behavior and emergent/urgent dental treatment need. Bivariate analysis was performed to investigate factors associated with dental attendance. Multivariable logistic regression based on principal component scores was performed to identify major psychological constructs associated with unnecessary dental avoidance and attendance. Among all the factors explored, inability to wear masks during dental treatment was most closely associated with the overall pattern of dental attendance among participants. Multivariable regression suggested that unnecessary dental avoidance was associated with perceived risk of infection in general and in dental settings, perceived impact of COVID-19 and dental problems on general health, and personal traits such as trust and anxiety. Unnecessary dental attendance was associated with optimism toward the epidemic and trust. Multidisciplinary efforts involving dental and medical professionals as well as psychologists are warranted to promote more widespread adoption, among the general public, of dental attendance behaviors compatible with dental treatment need during the COVID-19 epidemic.

Video surveillance plays a vital role in maintaining the social security although, until now, large uncertainty still exists in danger understanding and recognition, which can be partly attributed to intractable environment changes in the backgrounds. This article presents a brain-inspired computing of attention value of surrounding environment changes with a processes-based cognition model by introducing a ratio valueλof EC-implications within considered periods. Theoretical models for computation of warning level of EC-implications to the universal video recognition efficiency are further established. Imbedding (...) proposed models into the online algorithms is suggested as a future research priority towards precision security for critical applications and, furthermore, schemes for a practical implementation of such integration are also preliminarily discussed.

The authors find East Asians to be holistic, attending to the entire field and assigning causality to it, making relatively little use of categories and formal logic, and relying on "dialectical" reasoning, whereas Westerners, are more analytic, paying attention primarily to the object and the categories to which it belongs and using rules, including formal logic, to understand its behavior. The 2 types of cognitive processes are embedded in different naive metaphysical systems and tacit epistemologies. The authors speculate that the (...) origin of these differences is traceable to markedly different social systems. The theory and the evidence presented call into question long-held assumptions about basic cognitive processes and even about the appropriateness of the process–content distinction. (shrink)

This study aims to explore if local responsiveness pressure and subsidiary resources influence green management adoption of overseas subsidiaries, and to investigate the relationships between the level of green management adoption and performance. The 101 effective samples were collected from 583 Taiwanese firms, which are listed in the top 1000 manufactory firms and have invested in China. Though structural equation model analysis' empirical results indicate that local responsiveness pressure and subsidiary resources both have positive effects on the level of green (...) management adoption of the subsidiary. This study also suggests that the level of green management adoption is positively related to the subsidiary's performance. (shrink)

Language teacher research is conducive to the development of teachers’ teaching skills and professional careers. Thus, many English teacher education programs require student teachers to do research. However, some empirical findings suggest that English as a foreign language student teachers lack research motivation. Consequently, finding suitable interventions to increase their research motivation has become increasingly necessary. In light of the importance of research motivation intervention, this study involved designing an experiment to identify the effect of a value and interest intervention (...) including the sharing of positive research experiences to improve student teachers’ research motivation. Quantitative questionnaires and qualitative semi-structured interviews were used to gather evidence on the change in student teachers’ research motivation during the intervention. The interview data revealed that student teachers’ research motivation was influenced by their belief in the value of research to their teaching practice. The experiment results suggested that student teachers’ intrinsic and extrinsic research motivations both increased after the intervention. However, the intervention was not effective in curbing their failure avoidance tendency. Pedagogical implications of the results are discussed at the end of this article. (shrink)

This paper presents an integrated approach to plan smooth path for robots docking in unknown environments with obstacles. To determine the smooth collision-free path in obstacle environment, a tree structure with heuristic expanding strategy is designed as the foundation of path planning in this approach. The tree employs 3D Dubins curves as its branches and foundation for path feasibility evaluation. For the efficiency of the tree expanding in obstacle environment, intermediate nodes and collision-free branches are determined inspired by the elastic (...) band theory. A feasible path is chosen as the shortest series of branches that connects to the docking station after the sufficient expansion of the tree. Simulation results are presented to show the validity and feasibility of the proposed approach. (shrink)

Within the framework of pragma-dialectics, this paper analyzes the use of dissociations in the spokespersons’ replies at the press conferences held by the Chinese Ministry of Foreign Affairs between 2015 and 2017. As shown in the research results, to cut down the authority of their opponents in criticizing China and to convince the international general public of the Chinese standpoints, four subtypes of dissociation are used, which can be differentiated as: “distorted” Term I versus “authentic” Term II, “ambiguous” Term I (...) versus “univocal” Term II, “broadened” Term I versus “exact” Term II, and “narrowed” Term I versus “exact” Term II. The strategic maneuvering carried out by the spokespersons in confronting their immediate opponents by means of the various subtypes of dissociation is in the first place directed at their primary audience, i.e. the international general public. To make a convincing case, in using dissociations the spokespersons not only adapt in their strategic maneuvering to the demands of their primary audience but also in their selection from the topical potential and the presentational devices.

As part of a research project on confrontational maneuvering in the spokespersons’ argumentative replies at the regular press conferences of China’s Ministry of Foreign Affairs between 2015 and 2018, this article analyzes, within the framework of Pragma-Dialectics, how the spokespersons declare a standpoint at issue unallowed or indisputable in order to avoid having to resolve a difference of opinion as it is, according to the questioning journalist, presented by their immediate opponents. Starting from the various rationales the spokespersons presuppose to (...) be understood and regarded acceptable by the questioning journalist and the international general public, three subtypes of declaring a standpoint unallowed or indisputable are differentiated: the “Necessity Rationale” subtype, the “Desirability Rationale” subtype, and the “Feasibility Rationale” subtype. The confrontational maneuvering by declaring a standpoint unallowed or indisputable carried out by the spokespersons is directed both at the immediate opponent and at the international general public. However, it is the international general public that the spokespersons primarily intend to convince. For this purpose, they make in all three subtypes of the unallowed or indisputable declaration an effort to adapt their response to their primary audience’s demand by making strategic choices from the available topical potential and the available presentational devices.

In order to solve a series of problems brought about by rapid development of science and technology, it is necessary not only to conduct in-depth research on science and technology ethics, but also to strengthen ethics education in science and technology. China’s five technical universities exemplify the specific situation and characteristics of ethics at Chinese technical universities, and can be compared to the situation in South Africa. China’s ethics education in the 5TU emphasizes the use of traditional ideological and cultural (...) resources, and practical cases. The teaching methods focus on combining traditional Chinese ethics with foreign experience and teaching methods, aiming at cultivating students’ ability to solve specific problems in the real world. This paper also evaluates and reflects on the short-term and long-term effects of China’s ethics education in science and technology, revealing some special problems. Ethics education in science and technology at the 5TU is based on the principle of “unity of knowledge and behaviour”. It is hoped that China’s ethics education founded on traditional Chinese thought, can make a valuable contribution to the development of global engineering ethics. (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)

A result from a standard linear model course is that the variance of the ordinary least squares (OLS) coefficient of a variable will never decrease when including additional covariates into the regression. The variance inflation factor (VIF) measures the increase of the variance. Another result from a standard linear model or experimental design course is that including additional covariates in a linear model of the outcome on the treatment indicator will never increase the variance of the OLS coefficient of the (...) treatment at least asymptotically. This technique is called the analysis of covariance (ANCOVA), which is often used to improve the efficiency of treatment effect estimation. So we have two paradoxical results: adding covariates never decreases the variance in the first result but never increases the variance in the second result. In fact, these two results are derived under different assumptions. More precisely, the VIF result conditions on the treatment indicators but the ANCOVA result averages over them. Comparing the estimators with and without adjusting for additional covariates in a completely randomized experiment, I show that the former has smaller variance averaging over the treatment indicators, and the latter has smaller variance at the cost of a larger bias conditioning on the treatment indicators. Therefore, there is no real paradox. (shrink)

A geometric lattice is the lattice of closed subsets of a closure operator on a set which is zero-closure, algebraic, atomistic and which has the so-called exchange property. There are many profound results about this type of lattices, the most recent one of which, due to Czédli and Schimdt, says that a lattice L of finite length is semimodular if and only if L has a cover-preserving embedding into a geometric lattice G of the same length. The goal of our (...) paper is to offer the following result: a lattice of finite length is semimodular if and only if every cell in L is a 4-element Boolean lattice and the 7-element non-distributive atomistic lattice having 3 atoms is not a cover-preserving sublattice of L.
