    How Classy Servant Leader at Workplace? Linking Servant Leadership and Task Performance During the COVID-19 Crisis: A Moderation and Mediation Approach.Muhammad Zada,Shagufta Zada,Mudassar Ali,ZhangYong Jun,Nicolás Contreras-Barraza &Dante Castillo -2022 -Frontiers in Psychology 13.
    The COVID-19 pandemic has caused a record global crisis, particularly and extremely, for the service sectors. Due to extensive security measures, many service sector employees have to work remotely to maintain services. Drawing upon the conservation of resources theory, this research investigates the impact of servant leadership on the task performance of employees in virtual working environments during the COVID-19 crisis. Our theoretical model was tested using data collected from 335 individual employees in the education sector of Pakistan. SPSS version (...) 26.0 was applied to find the hypothesized relationship between the study variables. To find the indirect mediating effect, we applied Model 4; for moderation, we applied Model 1; and for the moderation and mediation effect, we applied Model 7 of the Process Macro model of Hayes. The results of the study revealed that servant leadership is positively related to task performance in a virtual environment during crises. Furthermore, psychological empowerment partially mediates the relationship between servant leadership and task performance. Perceived supervisor support positively moderates the relationship between servant leadership and task performance. Moreover, the indirect effect of servant leadership on task performance via psychological empowerment is moderated by perceived supervisor support. The results provided guidance to the educational sector on how to lead effectively in times of crisis when service sector employees work predominantly in virtual environments. The theoretical and practical implications of these findings are discussed. (shrink)

    Trust and Stock Price Synchronicity: Evidence from China.Baoyin Qiu,Junli Yu &KuoZhang -2020 -Journal of Business Ethics 167 (1):97-109.
    This paper investigates how social trust affects stock price synchronicity using a large sample of listed firms in China. We propose and provide evidence that social trust has a significantly positive impact on the amount of firm-specific information capitalized into stock prices. Further analyses indicate that firms located in regions of high social trust tend to have a smaller stock price crash risk and are less likely to engage in opportunistic behaviors than those in low-trust regions. Moreover, the positive role (...) of trust in increasing firm-specific return variations and discouraging corporate misbehaviors is more pronounced for SOEs than Non-SOEs. Evidence from 2SLS regressions supports a causal impact of social trust on stock price synchronicity. (shrink)

    Some Hesitant Fuzzy Linguistic Muirhead Means with Their Application to Multiattribute Group Decision-Making.Jun Wang,RuntongZhang,Xiaomin Zhu,Yuping Xing &Borut Buchmeister -2018 -Complexity 2018:1-16.
    The proposed hesitant fuzzy linguistic set is a powerful tool for expressing fuzziness and uncertainty in multiattribute group decision-making. This paper aims to propose novel aggregation operators to fuse hesitant fuzzy linguistic information. First, we briefly recall the notion of HFLS and propose new operations for hesitant fuzzy linguistic elements. Second, considering the Muirhead mean is a useful aggregation technology that can consider the interrelationship among all aggregated arguments, we extend it to hesitant fuzzy linguistic environment and propose new hesitant (...) fuzzy linguistic aggregation operators, such as the hesitant fuzzy linguistic Muirhead mean operator, the hesitant fuzzy linguistic dual Muirhead mean operator, the hesitant fuzzy linguistic weighted Muirhead mean operator, and the hesitant fuzzy linguistic weighted dual Muirhead mean operator. These operators can reflect the correlations among all HFLEs. Several desirable properties and special cases of the proposed operators are also studied. Furthermore, we propose a novel approach to MAGDM in a hesitant fuzzy linguistic context based on the proposed operators. Finally, we conduct a numerical experiment to demonstrate the validity of our method. Additionally, we compare our method with others to illustrate its merits and superiorities. (shrink)

    SNAP23 is selectively expressed in airway secretory cells and mediates baseline and stimulated mucin secretion.Binhui Ren,Zoulikha Azzegagh,Ana M. Jaramillo,Yunxiang Zhu,Ana Pardo-Saganta,Rustam Bagirzadeh,Jose R. Flores,Wei Han,Yong-jun Tang,Jing Tu,Denise M. Alanis,Christopher M. Evans,Michele Guindani,Paul A. Roche,Jayaraj Rajagopal,Jichao Chen,C. William Davis,Michael J. Tuvim &Burton F. Dickey -unknown
    Airway mucin secretion is important pathophysiologically and as a model of polarized epithelial regulated exocytosis. We find the trafficking protein, SNAP23, selectively expressed in secretory cells compared with ciliated and basal cells of airway epithelium by immunohistochemistry and FACS, suggesting that SNAP23 functions in regulated but not constitutive epithelial secretion. Heterozygous SNAP23 deletant mutant mice show spontaneous accumulation of intracellular mucin, indicating a defect in baseline secretion. However mucins are released from perfused tracheas of mutant and wild-type mice at the (...) same rate, suggesting that increased intracellular stores balance reduced release efficiency to yield a fully compensated baseline steady state. In contrast, acute stimulated release of intracellular mucin from mutant mice is impaired whether measured by a static imaging assay 5 min after exposure to the secretagogue ATP or by kinetic analysis of mucins released from perfused tracheas during the first 10 min of ATP exposure. Together, these data indicate that increased intracellular stores cannot fully compensate for the defect in release efficiency during intense stimulation. The lungs of mutant mice develop normally and clear bacteria and instilled polystyrene beads comparable to WT mice, consistent with these functions depending on baseline secretion that is fully compensated.

    The Impact of Occupational Community on the Quality of Internal Control.Shelagh Campbell,Yingqi Li,Junli Yu &ZhouZhang -2016 -Journal of Business Ethics 139 (2):271-285.
    Senior executives in major corporations have drawn attention in recent years for a range of unethical activities. Despite a rise in measures to protect against such lapses, executives still make decisions whether or not to comply with reporting standards, best practices, industry norms and legislation. The prior literature in this area addresses individual characteristics of decision makers and social networks between executives and boards of directors, but to this point has largely overlooked group dynamics of the executive team. Our study (...) addresses this gap and examines the relationship between an occupational community of top executives and the quality of internal control. We construct a unique measure for the executive occupational community based on CEO and CFO’s joint tenure. Our findings show that the number of years of CEO/cfo’s joint tenure is significantly and negatively associated with internal control weakness, suggesting that the longer the executive relationship, the lower the likelihood of internal control weakness. Our study indicates that the presence of an occupational community contributes to better internal control. (shrink)

    Correlation Between Resting Theta Power and Cognitive Performance in Patients With Schizophrenia.Yanxiang Cao,Chuanliang Han,Xing Peng,Ziyao Su,Gan Liu,Yixi Xie,YitingZhang,Jun Liu,PeiZhang,Wen Dong,Michel Gao,Sha Sha &Xixi Zhao -2022 -Frontiers in Human Neuroscience 16.
    ObjectiveSchizophrenia is a mental disorder that is characterized by progressive cognitive impairment. Objective measures of cognitive function may provide reliable neurobiomarkers for patients with schizophrenia. The goal of the current work is to explore the correlation between resting theta power and cognitive performance in patients with schizophrenia.MethodsTwenty-two patients with schizophrenia and 23 age-, sex-, and education-matched healthy controls were included in this study. The MATRICS Consensus Cognitive Battery was used for cognitive evaluation and the Positive and Negative Syndrome Scale for (...) evaluation of clinical symptoms. EEGs were acquired in the resting state with closed and opened eyes. Between the two groups, we compared the relative theta power and examined their relationship with cognitive performance.ResultsCompared to healthy controls, patients with schizophrenia showed significantly higher theta power, both with eyes closed and open. When the eyes were open, negative correlations were found in patients with schizophrenia between theta power in the central and parietal regions with processing speed scores, and between the theta power of the Pz electrode and verbal learning and reasoning and problem-solving scores. In the control group, theta power over the Fz electrode was negatively correlated with processing speed.ConclusionsOur findings showed that theta activity increased in certain brain regions during resting state in schizophrenia. Negative associations between resting theta power over the parietal-occipital regions with MCCB domains scores suggest that altered theta activity can be used as a neurobiological indicator to predict cognitive performance.

    Functional Network Alterations as Markers for Predicting the Treatment Outcome of Cathodal Transcranial Direct Current Stimulation in Focal Epilepsy.Jiaxin Hao,Wenyi Luo,Yuhai Xie,Yu Feng,Wei Sun,Weifeng Peng,Jun Zhao,PumingZhang,Jing Ding &Xin Wang -2021 -Frontiers in Human Neuroscience 15.
    Background and PurposeTranscranial direct current stimulation is an emerging non-invasive neuromodulation technique for focal epilepsy. Because epilepsy is a disease affecting the brain network, our study was aimed to evaluate and predict the treatment outcome of cathodal tDCS by analyzing the ctDCS-induced functional network alterations.MethodsEither the active 5-day, −1.0 mA, 20-min ctDCS or sham ctDCS targeting at the most active interictal epileptiform discharge regions was applied to 27 subjects suffering from focal epilepsy. The functional networks before and after ctDCS were (...) compared employing graph theoretical analysis based on the functional magnetic resonance imaging data. A support vector machine prediction model was built to predict the treatment outcome of ctDCS using the graph theoretical measures as markers.ResultsOur results revealed that the mean clustering coefficient and the global efficiency decreased significantly, as well as the characteristic path length and the mean shortest path length at the stimulation sites in the fMRI functional networks increased significantly after ctDCS only for the patients with response to the active ctDCS. Our prediction model achieved the mean prediction accuracy of 68.3% after the nested cross validation. The mean area under the receiver operating curve was 0.75, which showed good prediction performance.ConclusionThe study demonstrated that the response to ctDCS was related to the topological alterations in the functional networks of epilepsy patients detected by fMRI. The graph theoretical measures were promising for clinical prediction of ctDCS treatment outcome. (shrink)

    Networking of Smart Meters Based on Time-Varying Feature of Low-Voltage Power Line Channel in Microgrid.Ya-Xin Huang,Xiao-DiZhang,Fei Yu,Yong-Qing Wei &Hai-LongZhang -2021 -Complexity 2021:1-16.
    In order to manage the electricity consumption information of microgrid users, the reliability of electricity information collection is studied in this paper. The normal communication between the acquisition terminal and the smart meter is a key factor affecting the accurate collection of power information; it is the basis for ensuring the operation of the microgrid as well. In order to improve the reliability of the low power line communication between the acquisition terminal and smart meters, this article first uses the (...) static networking method to layer the smart meters and select relays from them and then select the optimal communication path based on integrating communication quality and relay forwarding number dynamically, which could avoid the signal conflict problem caused by simultaneous communication. Finally, by analyzing the influence of the time-varying power line channel on the smart meter communication, a method based on the integrated communication quality and the relay number to consider the time variability of low power line communication is proposed. Choosing the optimal path of the smart meters when the communication path is abnormal can not only establish a new communication path for communication in time, but also avoid communication failures caused by the time-varying channel. Through MATLAB simulation, the time-varying dynamic network of the power line channel is introduced in this paper, which improves the reliability of the smart meter communication and has certain guiding significance for the actual smart meter network construction in microgrid.

    Do Suppliers Applaud Corporate Social Performance?MinZhang,Lijun Ma,Jun Su &WenZhang -2014 -Journal of Business Ethics 121 (4):543-557.
    The influence of corporate social performance on stakeholders is one of the focal issues in corporate social responsibility research. Using data of listed companies in China, this paper examines whether CSR behavior in the form of charitable donations garners a positive reaction from suppliers. Results derived from both level and change model regressions show that superior CSP makes it easier for a firm to obtain trade credit from suppliers, although the effect is significant only in non-state-owned enterprises. The results are (...) robust to various measures of CSP and endogeneity tests. The results support the strategic philanthropy view and apply stakeholder theory in supply chain, that strategic CSR can help firms to attract suppliers and consolidate cooperative relationships with them, which in turn benefits the firms in terms of more trade credit financing from suppliers. This paper also shows that state-owned enterprises and non-SOEs have different CSR intentions and use CSR to achieve strategic goals in different ways. The conclusions drawn from this study provide practical guidance on CSR strategy, suggesting that CSR activities can help a firm in transition economies to enhance its corporate image, establish and consolidate the good relationship with suppliers, and obtain economic benefits or achieve long-term business objectives.

    Corporate Philanthropy and Tunneling: Evidence from China.Jun Chen,Wang Dong,Jamie Tong &FeidaZhang -2018 -Journal of Business Ethics 150 (1):135-157.
    This paper examines the association between corporate philanthropy and tunneling by controlling shareholders. Using a unique dataset from China, the paper finds evidence that firms donating more are less likely to tunnel. The negative association between philanthropy and tunneling is stronger when firms are faced with more severe agency conflicts, as indicated by lower largest shareholding, fewer growth opportunities, lower state ownership, and weaker product market competition. The results suggest that companies engaging in philanthropy have incentives to enhance their reputations (...) and improve their relationships with stakeholders. (shrink)

    The Economic Consequences of Labor Unionization: Evidence from Stock Price Crash Risk.Jun Chen,Jamie Y. Tong,Wenming Wang &FeidaZhang -2019 -Journal of Business Ethics 157 (3):775-796.
    This study investigates the impact of labor unionization on stock price crash risk. We find that labor unionization is negatively associated with stock price crash risk. Such negative relation is more pronounced when firms can intimate more credible evidence on unfavorable prospects and when firms face more powerful labor unions. Our findings are consistent with the notion that firms take strategic actions to reduce the bargaining advantages enjoyed by labor unions and that labor unions force firms to take less risky (...) investments and discontinue underperformed projects more timely, which leads to lower stock price crash risk.

    How Does Culture Shape Creativity? A Mini-Review.Yong Shao,ChenchenZhang,Jing Zhou,Ting Gu &Yuan Yuan -2019 -Frontiers in Psychology 10:434004.
    The purpose of this study was to examine how culture shapes creativity by reviewing empirical findings across diverse studies. The impact of culture on creativity is typically manifested in three ways: (a) people from different cultures or settings have distinct implicit and/or explicit conceptions of creativity; (b) individuals from different cultures, particularly those from individualist and collectivist cultures, show differences in preferred creative processes and creative processing modes (e.g., usefulness seems more important than novelty in the East, whereas novelty seems (...) equally important as usefulness, if not more so, in the West) when they are engaged in creative endeavors; (c) creativity may be assessed using different measures based on culture-related contents or materials, and findings are accurate only when culturally appropriate or culturally fair measures are used. Potential implications and future directions are also proposed. (shrink)

    Mathematics in Context: A Case in Early Nineteenth-Century Korea.JunYong Hoon -2006 -Science in Context 19 (4):475-512.
    ArgumentThis paper aims to show how a nineteenth-century Korean scholar's mathematical study reflects the Korean intellectual environment of his time by focusing on the rule of false double position and the method of root extraction. There were two major trends in Korean mathematics of the early nineteenth century: the first was “Tongsan,” literally “Eastern Mathematics,” which largely depended on Chinese mathematics of the Song and Yuan period adopting counting rod calculation; the second trend was Western mathematics, which was transmitted by (...) the Jesuits and their Chinese collaborators from the late sixteenth century. There was also an intellectual transition in late eighteenth-century Korea when mathematics, which had been of only minor interest for Confucian scholars, became an important part of Confucian pursuits. We can gain an insight into the history of mathematics in Korea by examining and understanding Hong Kil-chu's mathematical studies and the context of the academic world of his time. (shrink)

    From Motivation to Organizational Identity of Members in Non-profit Organizations: The Role of Collectivism.Yong Li &YutingZhang -2020 -Frontiers in Psychology 11.
    This study contributes to our understanding of organizational identity through dichotomous motivations of altruism and egoism in nonprofit organizations. By applying an empirical analysis of NPO members, organizational identity is found to be well explained by altruistic motivation and egoistic motivation. More importantly, this study finds that collectivism positively moderates the relationship between altruistic motivation and organizational identity, and negatively moderates the relationship between egoistic motivation and organizational identity. It is noticeable that altruistic motivations have a stronger impact on organizational (...) identity when collectivism is high, while egoistic motivations have a stronger impact on organizational identity when collectivism is low. Finally, this study generates helpful management implications based on research findings. It is suggested that the managers of NPOs could enhance members’ organizational identity by taking motivations and collectivism into consideration, that is to say, in order to build up organizational identity of NPO members, both righteousness and shared interests matter simultaneously.

    In this paper, we devise a network that consists of argumentation schemes and critical questions that participants in debates can use to easily construct arguments that attack or support former arguments. As a prototype, we build a potential network of argumentation schemes and critical questions with a practical reasoning scheme at its center. The usefulness of a NASCQ in constructing and reconstructing complex arguments and in formal argumentation is also explored along with argumentation more broadly.

    A Machine Learning Approach to Evaluate the Performance of Rural Bank.Jun Wei,Tao Ye &ZheZhang -2021 -Complexity 2021:1-10.
    In the current performance evaluation works of commercial banks, most of the researches only focus on the relationship between a single characteristic and performance and lack a comprehensive analysis of characteristics. On the other hand, they mainly focus on causal inference and lack systematic quantitative conclusions from the perspective of prediction. This paper is the first to comprehensively investigate the predictability of multidimensional features on commercial bank performance using boosting regression tree. The dimensionality in the financial-related fields is relatively high. (...) There are not only observable price data, financial fundamentals data, etc., but also many unobservable undisclosed data and undisclosed events; more sources of income cannot be explained by existing models. Aiming at the characteristics of commercial bank data, this paper proposes an adaptively reduced step size gradient boosting regression tree algorithm for bank performance evaluation. In this method, a random subsample sampling is performed before training each regression tree. The adaptive reduction step size is used to replace the reduction step size setting of the original algorithm, which overcomes the shortcomings of low accuracy and poor generalization ability of the existing regression decision tree model. Compared to the BIRCH algorithm for classification of existing data, our proposed gradient boosting regression tree algorithm with adaptively reduced step size obtains better classification results. This paper empirically uses data from rural banks in 30 provinces in China to classify the different characteristics of rural banks’ performance in order to better evaluate their performance.

    Dynamics of a Predator-Prey Model with Fear Effect and Time Delay.Junli Liu,Pan Lv,Bairu Liu &TaileiZhang -2021 -Complexity 2021:1-16.
    In this paper, we propose a time-delayed predator-prey model with Holling-type II functional response, which incorporates the gestation period and the cost of fear into prey reproduction. The dynamical behavior of this system is both analytically and numerically investigated from the viewpoint of stability, permanence, and bifurcation. We found that there are stability switches, and Hopf bifurcations occur when the delay τ passes through a sequence of critical values. The explicit formulae which determine the direction, stability, and other properties of (...) the bifurcating periodic solutions are given by using the normal form theory and center manifold theorem. We perform extensive numerical simulations to explore the impact of some important parameters on the dynamics of the system. Numerical simulations show that high levels of fear have a stabilizing effect while relatively low levels of fear have a destabilizing effect on the predator-prey interactions which lead to limit-cycle oscillations. We also found that the model with or without a delay-dependent factor can have a significantly different dynamics. Thus, ignoring the delay or not including the delay-dependent factor might result in inaccurate modelling predictions. (shrink)

    Computing motivation: Incentive salience boosts of drug or appetite states.Kent C. Berridge,JunZhang &J. Wayne Aldridge -2008 -Behavioral and Brain Sciences 31 (4):440-441.
    Current computational models predict reward based solely on learning. Real motivation involves that but also more. Brain reward systems can dynamically generate incentive salience, by integrating prior learned values with even novel physiological states (e.g., natural appetites; drug-induced mesolimbic sensitization) to cause intense desires that were themselves never learned. We hope future computational models may capture this too.

    Emotional Labor in Teaching Chinese as an Additional Language in a Family-Based Context in New Zealand: A Chinese Teacher’s Case.Chunrong Bao,Lawrence JunZhang &Helen R. Dixon -2022 -Frontiers in Psychology 13.
    New Zealand is a multilingual and multicultural society, where English, Maori, and the New Zealand sign language are designated as its official languages. However, some heritage languages are also taught either within or outside the national education system. During the past decade, an increasing number of students have chosen Mandarin Chinese as an additional language because of its fast-growing importance. To date, studies regarding CAL are mainly based on the mainstream Chinese programs or online platforms, with less attention paid to (...) other types of teaching contexts where there also exist many potential challenges awaiting teachers. To fill in this gap, this study, based on a teaching program consisting of two families in New Zealand, explored the trajectories of a CAL teacher’s emotional labor for 47 weeks to understand how she managed her emotions when she taught the language as well as balanced the relationship among the three parties: the institution, the two families, and herself. Narrative inquiry was used as a methodological approach. The data involved written and spoken narratives. Using inductive and deductive thematic analysis, findings revealed her different understandings of the emotional labor in the two families, respectively, during the program. Further analysis of the data revealed some factors that impacted her emotional labor and how they impacted her teaching in a family-based context. We concluded our study with a discussion of the implications of these findings for teaching CAL in similar contexts. (shrink)

    More than just statics: Static and temporal dynamic changes in intrinsic brain activity in unilateral temporal lobe epilepsy.Chengru Song,XiaonanZhang,Shaoqiang Han,Keran Ma,Kefan Wang,Xinyue Mao,Yajun Lian,XianchangZhang,Jinxia Zhu,YongZhang &Jingliang Cheng -2022 -Frontiers in Human Neuroscience 16.
    BackgroundTemporal lobe epilepsy is the most prevalent refractory focal epilepsy and is more likely accompanied by cognitive impairment. The fully understanding of the neuronal activity underlying TLE is of great significance.ObjectiveThis study aimed to comprehensively explore the potential brain activity abnormalities affected by TLE and detect whether the changes were associated with cognition.MethodsSix static intrinsic brain activity indicators [amplitude of low-frequency fluctuation, fractional ALFF, regional homogeneity, degree centrality, global signal correlation, and voxel-mirrored homotopic connectivity ] and their corresponding dynamic indicators, (...) such as dynamic ALFF, dynamic fALFF, dynamic ReHo, dynamic DC, dynamic VMHC, and dynamic GSCorr, in 57 patients with unilateral TLE and 42 healthy volunteers were compared. Correlation analyses were also performed between these indicators in areas displaying group differences and cognitive function, epilepsy duration, and severity.ResultsMarked overlap was present among the abnormal brain regions detected using various static and dynamic indicators, primarily including increased ALFF/dALFF/fALFF in the bilateral medial temporal lobe and thalamus, decreased ALFF/dALFF/fALFF in the frontal lobe contralateral to the epileptogenic side, decreased fALFF, ReHo, dReHo, DC, dDC, GSCorr, dGSCorr, and VMHC in the temporal neocortex ipsilateral to the epileptogenic foci, decreased dReHo, dDC, dGSCorr, and dVMHC in the occipital lobe, and increased ALFF, fALFF, dfALFF, ReHo, and DC in the supplementary motor area ipsilateral to the epileptogenic foci. Furthermore, most IBA indicators in the abnormal brain region significantly correlated with the duration of epilepsy and several cognitive scale scores.ConclusionThe combined application of static and dynamic IBA indicators could comprehensively reveal more real abnormal neuronal activity and the impairment and compensatory mechanisms of cognitive function in TLE. Moreover, it might help in the lateralization of epileptogenic foci and exploration of the transmission and inhibition pathways of epileptic activity. (shrink)

    Effect of Product Presentation Videos on Consumers' Purchase Intention: The Role of Perceived Diagnosticity, Mental Imagery, and Product Rating.Zhendong Cheng,Bingjia Shao &YongZhang -2022 -Frontiers in Psychology 13.
    The product presentation videos on E-commerce platforms have a significant influence on consumers' purchase decisions, and enterprises have focused on choosing the type of product presentation videos. Based on the resource matching theory, mental imagery theory and cue utilization theory, this study investigated the influence of product presentation videos type on consumers' purchase intention and the moderating effect of product rating. Through three pre-experiments and two formal experiments, the results showed that the product usage video has a stronger effect on (...) consumers' purchase intention more than the product appearance video, which is mediated by perceived diagnosticity and mental imagery. In addition, product rating moderated the influence of product presentation videos type on consumers' purchase intention. The product usage video would improve consumers' purchase intention more than the product appearance video when the product rating is high; however, there is no significant difference in the impact of two types of videos on consumers' purchase intention when the product rating is low. This study supplements the research on product presentation videos and provides a reference for online retailers to select effective product presentation videos. (shrink)

    Authoring Selves in Language Teaching: A Dialogic Approach to Language Teacher Psychology.Shan Chen,Lawrence JunZhang &Judy M. Parr -2022 -Frontiers in Psychology 13.
    The teacher self is a composite psychological construct which encompasses the cognitive, affective, emotional, and social dimensions of teaching. This qualitative study draws on Bakhtin’s concepts of dialogism, answerability, and addressivity to discuss how English language teachers negotiated the shifting and conflictive context to construct selves in relation to the promoted communicative language teaching approach. Based on narrative interviews and classroom observations with five tertiary English teachers in China, we found that these teachers were actively engaged in the dialog with (...) their prior learning experiences and active, responsive in answering their contexts while authoring selves in everyday teaching practice. The multiple-case study data support a Bakhtinian understanding that teachers are active users and producers of theory in their own right, highlighting teachers’ agency, creativity, and autonomy. Based on Bakhtin’s dialogism and the case study findings, we bring cognition, identity and practice together and conceptualize the teacher self as having multiple facets and layers: the autobiographical self, the discursive self, and the pedagogical self. The three selves are constitutive of the consummated whole of the teacher self instead of being separate entities functioning individually. The study is concluded with implications for language teacher education and teacher development. (shrink)

    A Sociocultural Perspective on English-as-a-Foreign-Language (EFL) Teachers’ Cognitions About Form-Focused Instruction.Qiang Sun &Lawrence JunZhang -2021 -Frontiers in Psychology 12.
    There has been much research into teacher beliefs about teaching and learning as seen in the general teacher education literature. In the field of language teacher education, this line of research has been evolving, with the recent trend being streamlined into “teacher cognition” as a generic or umbrella term. Despite increasing amounts of research output so far, research into foreign language teachers’ cognitions about their own teaching and decision-making is still insufficient, particularly with regard to university-level English-as-a-foreign-language (EFL) teachers in (...) China. Drawing on Vygotsky’s Sociocultural Theory, this qualitative research focused on EFL teachers’ cognitions about form-focused instruction in Chinese university settings. It intended to discover how teachers’ cognitions changed when they were expected to teach in actual classrooms and what factors contributed to these changes. Data collected from four teacher-participants through semi-structured interviews, classroom observations and follow-up stimulated recall interviews showed participants’ support forfocus-on-forminstruction, which means they not only paid attention to the grammatical form of the language but also to the meaning it is intended to convey. However, data also showed that the teacher-participants shifted fromfocus-on-formtofocus-on-formSinstruction in actual teaching, which suggests that they might have realized the challenges of carrying out teaching activities surroundingfocus-on-formand would like to take an easier approach by only teaching the grammar of the language byfocusing on formS. Such incongruences are interpreted with reference to a plethora of sociocultural factors including traditional Chinese thinking and institutional expectations. The implications of the findings for stakeholders in universities, including faculty members, students, and curriculum developers in similar contexts, are also discussed. (shrink)

    The Dynamic Features of Lip Corners in Genuine and Posed Smiles.Hui Guo,Xiao-HuiZhang,Jun Liang &Wen-Jing Yan -2018 -Frontiers in Psychology 9:310840.
    The smile is a frequently expressed facial expression that typically conveys a positive emotional state and friendly intent. However, human beings have also learned how to fake smiles, typically by controlling the mouth to provide a genuine-looking expression. This is often accompanied by inaccuracies that can allow others to determine that the smile is false. Mouth movement is one of the most striking features of the smile, yet our understanding of its dynamic elements is still limited. The present study analyzes (...) the dynamic features of lip corners, and considers how they differ between genuine and posed smiles. Employing computer vision techniques, we investigated elements such as the duration, intensity, speed, symmetry of the lip corners, and certain irregularities in genuine and posed smiles obtained from the UvA-NEMO Smile Database. After utilizing the facial analysis tool OpenFace, we further propose a new approach to segmenting the onset, apex, and offset phases of smiles, as well as a means of measuring irregularities and symmetry in facial expressions. We extracted these features according to 2D and 3D coordinates, and conducted an analysis. The results reveal that genuine smiles have higher values for onset, offset, apex, and total durations, as well as offset displacement, and a variable we termed Irregularity-b (the SD of the apex phase) than do posed smiles. Conversely, values tended to be lower for onset and offset Speeds, and Irregularity-a (the rate of peaks), Symmetry-a (the correlation between left and right facial movements), and Symmetry-d (differences in onset frame numbers between the left and right faces). The findings from the present study have been compared to those of previous research, and certain speculations are made. (shrink)

    Self-Compassion and Subjective Well-Being Mediate the Impact of Mindfulness on Balanced Time Perspective in Chinese College Students.Jingjing Ge,Jun Wu,Kesheng Li &Yong Zheng -2019 -Frontiers in Psychology 10:323160.
    Balanced time perspective is associated with optimal social functioning and facilitates adaptation to pressure and changes in the environment. Previous studies have found that mindfulness is positively associated with and might promote balanced time perspective. However, the mechanism through which mindfulness affects balanced time perspective remains unexplored. The purpose of the present study was to investigate the mediating role of self-compassion and subjective well-being in the relationship between mindfulness and balanced time perspective. A total of 754 Chinese college students, aged (...) 17–27 years, completed the Chinese versions of the Five-Facet Mindfulness Questionnaire, Self-Compassion Scale, Subjective Well-Being Scale, and Zimbardo Time Perspective Inventory. There were significant positive correlations between mindfulness, self-compassion, subjective well-being, and balanced time perspective. Structural equation modeling indicated that in addition to the direct influence of mindfulness on balanced time perspective, self-compassion and subjective well-being played a partial mediating role. On the basis of these findings, we conclude that mindfulness has an important positive influence on balanced time perspective, and highlight the crucial role of the self-compassion in cultivating an individual's balanced time perspective. Limitations of the present study are also discussed. (shrink)

    Which is to blame: Instrumental rationality, or common knowledge?Matt Jones &JunZhang -2003 -Behavioral and Brain Sciences 26 (2):166-167.
    Normative analysis in game-theoretic situations requires assumptions regarding players' expectations about their opponents. Although the assumptions entailed by the principle of common knowledge are often violated, available empirical evidence – including focal point selection and violations of backward induction – may still be explained by instrumentally rational agents operating under certain mental models of their opponents.

    Teacher Written Feedback on English as a Foreign Language Learners’ Writing: Examining Native and Nonnative English-Speaking Teachers’ Practices in Feedback Provision.Xiaolong Cheng &Lawrence JunZhang -2021 -Frontiers in Psychology 12:629921.
    While previous studies have examined front-line teachers’ written feedback practices in second language (L2) writing classrooms, such studies tend to not take teachers’ language and sociocultural backgrounds into consideration, which may mediate their performance in written feedback provision. Therefore, much remains to be known about how L2 writing teachers with different first languages (L1) enact written feedback. To fill this gap, we designed an exploratory study to examine native English-speaking (NES) and non-native English-speaking (NNES) (i.e., Chinese L1) teachers’ written feedback (...) practices in the Chinese tertiary context. Our study collected 80 English as a foreign language (EFL) students’ writing samples with teacher written feedback and analyzed them from three aspects: Feedback scope, feedback focus, and feedback strategy. The findings of our study revealed that the two groups of teachers shared similar practices regarding feedback scope and feedback strategies. Both NES and NNES EFL teachers used a comprehensive approach to feedback provision, although NNES teachers provided significantly more feedback points than their NES peers and they delivered their feedback directly and indirectly. However, their practices differed greatly with regard to feedback focus. Specifically, when responding to EFL students’ writing, NES teachers showed more concern with global issues (i.e., content and organization), whereas NNES teachers paid more attention to linguistic errors. With a surge in the recruitment of expatriate NES and local NNES English teachers in China and other EFL countries, our study is expected to make a contribution to a better understanding of the two groups of EFL teachers’ pedagogical practices in written feedback provision and generate important implications for their feedback provision.

    Relationships Between Job Stress, Psychological Adaptation and Internet Gaming Disorder Among Migrant Factory Workers in China: The Mediation Role of Negative Affective States.He Cao,KechunZhang,Danhua Ye,Yong Cai,Bolin Cao,Yaqi Chen,Tian Hu,Dahui Chen,Linghua Li,Shaomin Wu,Huachun Zou,Zixin Wang &Xue Yang -2022 -Frontiers in Psychology 13:837996.
    Factory workers make up a large proportion of China’s internal migrants and may be highly susceptible to job and adaptation stress, negative affective states (e.g., depression and anxiety), and Internet gaming disorder (IGD). This cross-sectional study investigated the relationships between job stress, psychological adaptation, negative affective states and IGD among 1,805 factory workers recruited by stratified multi-stage sampling between October and December 2019. Structural equation modeling (SEM) was conducted to test the proposed mediation model. Among the participants, 67.3% were male (...) and 71.7% were aged 35 years old or below. The prevalence of probable depression, probable anxiety, and IGD was 39.3, 28.7, and 7.5%. Being male, younger age, and shorter duration of living in Shenzhen were associated with higher IGD scores. Job stress was significantly associated with IGD (β = 0.11,p= 0.01) but not with negative affective states (β = 0.01,p= 0.77). Psychological adaptation was significantly associated with negative affective states (β = −0.37,p 0.05). Negative affective states were positively associated with IGD (β = 0.27,p< 0.001). The indirect effect of psychological adaptation (β = −0.10,p= 0.004) but not job stress (β = 0.003,p= 0.77) on IGD through negative affective states was statistically significant. The observed psychological correlates and mechanisms are modifiable, and can inform the design of evidence-based prevention programs for depression, anxiety, and IGD in this population. (shrink)
