Revisiting Grammatical Complexity in L2 Writing via Exploratory Factor Analysis.Ge Lan,Xiaorui Li &Qiusi Zhang -2022 -Frontiers in Psychology 13.detailsSince the 1990s, grammatical complexity has received substantial research attention in applied linguistics. The representation of grammatical complexity has expanded in L2 writing with the application of diverse measures in empirical studies in the recent three decades. In response to this situation, we found it important to revisit grammatical complexity, and an exploratory factor analysis was applied to explore latent dimensions of grammatical complexity in L2 writing. We analyzed Lu’s 14 grammatical complexity measures in the L2 corpus of the British (...) Academic Written English Corpus. We then proposed a four-factor model with “clausal subordination,” “phrasal construction”, “global length unit” and “others.” The four factors generally align with the types of grammatical complexity proposed in Lu, but differences on six measures are also found. Noteworthy points were discussed to interpret the reasons behind the differences. Research implications are provided to show further research directions. (shrink)
Comparison of Facial Muscle Activation Patterns Between Healthy and Bell’s Palsy Subjects Using High-Density Surface Electromyography.Han Cui,Weizheng Zhong,Zhuoxin Yang,Xuemei Cao,Shuangyan Dai,Xingxian Huang,Liyu Hu,Kai Lan,Guanglin Li &Haibo Yu -2021 -Frontiers in Human Neuroscience 14.detailsFacial muscle activities are essential for the appearance and communication of human beings. Therefore, exploring the activation patterns of facial muscles can help understand facial neuromuscular disorders such as Bell’s palsy. Given the irregular shape of the facial muscles as well as their different locations, it should be difficult to detect the activities of whole facial muscles with a few electrodes. In this study, a high-density surface electromyogram system with 90 electrodes was used to record EMG signals of facial muscles (...) in both healthy and Bell’s palsy subjects when they did different facial movements. The electrodes were arranged in rectangular arrays covering the forehead and cheek regions of the face. The muscle activation patterns were shown on maps, which were constructed from the Root Mean Square values of all the 90-channel EMG recordings. The experimental results showed that the activation patterns of facial muscles were distinct during doing different facial movements and the activated muscle regions could be clearly observed. Moreover, two features of the activation patterns, 2D correlation coefficient and Centre of Gravity were extracted to quantify the spatial symmetry and the location of activated muscle regions respectively. Furthermore, the deviation of activated muscle regions on the paralyzed side of a face compared to the healthy side was quantified by calculating the distance between two sides of CGs. The results revealed that corr2 of the activated facial muscle region in Bell’s palsy subjects was significantly lower than that in healthy subjects, while CG distance of activated facial region in Bell’s palsy subjects was significantly higher than that in healthy subjects. The correlation between corr2 of these regions and Bell’s palsy [assessed by the Facial Nerve Grading Scale 2.0] was also significant in Bell’s palsy subjects. The spatial information on activated muscle regions may be useful in the diagnosis and treatment of Bell’s palsy in the future. (shrink)
From Deep-Level Similarity to Subordinate Moqi: The Mediating Role of Leader-Member Exchange.Lan Li,Xingshan Zheng &Siwei Sun -2022 -Frontiers in Psychology 13.detailsFostering subordinate moqi is a significant method to improve the cooperating quality and promote positive outcomes. However, little is known about the influencing factors and mechanisms of subordinate moqi. To address this issue and explore the influencing factors of subordinate moqi, we draw on self-categorization theory to develop a mediation model to examine whether and how deep-level similarity affects subordinate moqi, casting the leader-member exchange as a mediator. A two-wave online survey was conducted and 316 data was collected. A Structure (...) Equation Modeling analysis was used to test all hypotheses with Mplus 7. Results showed that the deep-level similarity could positively predict subordinate moqi and LMX, respectively. Additionally, LMX was a significant predictor of subordinate moqi as well as it mediated the positive relationships between deep-level similarity and subordinate moqi. These findings expand our understanding of the antecedents of subordinate moqi. It is suggested that developing subordinates’ deep-level similarity with supervisors and LMX relationships are instrumental in cultivating subordinate moqi which promote positive outcomes. Organizations should integrate effective management programs into managerial strategies to enhance deep-level similarity and LMX, in turn, fosters subordinate moqi. (shrink)
The functional connectivity of the basal ganglia subregions changed in mid-aged and young males with chronic prostatitis/chronic pelvic pain syndrome.Xi Lan,Xuan Niu,Wei-Xian Bai,Hai-Ning Li,Xin-Yi Zhu,Wen-Jun Ma,Jian-Long Li,Wang-Huan Dun,Ming Zhang &Juan He -2022 -Frontiers in Human Neuroscience 16:1013425.detailsBackgroundThe Basal ganglia (BG) played a crucial role in the brain-level mechanisms of chronic pain disorders. However, the functional changes of BG in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are still poorly understood. This study investigated the BG subregions’ resting-state functional connectivity (rs-FC) in CP/CPPS patients compared with healthy controls.MethodsTwenty eight patients with CP/CPPS and 28 age- and education-matched healthy males underwent clinical measurements and 3T brain MR imaging, including T1-weighted structural images and resting-state functional imaging. The data were analyzed (...) by the seeded-based rs-FC analysis. Then, a machine learning method was applied to assess the feasibility of detecting CP/CPPS patients through the changed rs-FC.ResultsCompared with healthy males, patients presented decreased rs-FC between the BG subregions and right middle cingulate cortex, and correlated with pain (r = 0.51, p-uncorrected = 0.005) and urinary symptoms (r = –0.4, p-uncorrected = 0.034). The left superior temporal gyrus and right supramarginal gyrus showed decreased rs-FC with the BG subregions as well. The area under the receiver operating characteristic curve of 0.943 (accuracy = 80%, F1-score = 80.6%) was achieved for the classification of CP/CPPS patients and healthy males with support vector machine (SVM) based on the changed rs-FC.ConclusionThese findings provide evidence of altered BG subregions’ rs-FC in CP/CPPS, which may contribute to our understanding of the BG’s role in CP/CPPS.

Managerial Morality and Philanthropic Decision-Making: A Test of an Agency Model.Cheng-Li Huang &Ju-Lan Tsai -2015 -Journal of Business Ethics 132 (4):795-811.detailsWhile previous authors have broadly examined the motivations and outcomes of the philanthropic activities of organizations, the present study extends Miska et al.’s rationalistic approach to examine the degree to which managerial philanthropic decision-making behaviour is dominated by morality. This study also tackles the question of whether this relationship is moderated by the strength of the geographical proximity and amount of the donation within an agency framework. To probe the radical agency problem and the effect of intervention, an alternative heuristic (...) scenario is also developed to provide evidence that managers under the same moral level show significant differences in donation intention under a variety of agency conditions. The results indicate a significant difference between the existence and non-existence of agency problems in charitable decision-making by managers high in idealism and relativism; however, at the same time, philanthropic behaviour is intertwined with various dilemma-related contexts. These findings bridge the gap in the literature on ethics and corporate social responsibility, and challenge current thinking on corporate governance mechanisms in this area by offering researchers and practitioners an integrated model that responds to a strong sceptical bias or a high premium placed on morality.

Performance pressure and annual report text manipulation: Evidence from China.Yanxi Li,Delin Meng &Lan Wang -forthcoming -Business Ethics, the Environment and Responsibility.detailsBuilding on attribution theory, this study investigates the antecedents of corporate annual report text manipulation from the perspective of managerial performance pressure. Using a data set comprising 15,076 samples from companies listed on China's Shanghai and Shenzhen A-share markets between 2009 and 2021, we reveal that as management faces performance pressure, they tend to increase content about external environmental risk and policy uncertainty in annual reports due to actor–observer bias. When incorporating Confucian cultural factors into the research framework, the study (...) found that the strength of Confucian culture mitigates the correlation between the pressure of management performance and annual report manipulation. However, the level of marketization where a corporation is located can undermine the ethical norms upheld by Confucian culture. In additional analysis, we also discovered that the longer the duration of performance pressure, the greater the extent of manipulation within the annual reports initiated by the management. Interestingly, the social performance pressure generated from ESG performance also positively influences annual report textual manipulation, compared to operational performance pressure. This study explores the impact of management performance pressure on information disclosure decisions from the perspective of performance attribution, not only extending the boundaries of attribution theory but also providing guidance for policymakers to enhance the supervision of annual report disclosures and for capital market investors to optimize investment decisions.

Shaping the Future of Business Sustainability: LDA Topic Modeling Insights, Definitions, and Research Agenda.Lan Li &Fred Lemke -forthcoming -Journal of Business Ethics:1-66.detailsThis article offers a comprehensive overview of Business Sustainability (BuS), and directly addresses the lack of consensus around this important concept. Through a mixed-methods approach, we conduct the first systematic literature review of BuS employing Latent Dirichlet Allocation (LDA) topic modeling to uncover hidden thematic structures, Narrative Synthesis to refine and extend BuS definitions within different contexts, and the LDA-HSIM method to classify topics and design a new framework. We analyzed an extensive dataset comprising 92,311 articles sourced from 11,579 journal (...) outlets. From this dataset, we identified 9,561 articles suitable for LDA topic modeling by applying funnel criteria, focusing on articles with clear theoretical underpinnings. A text extraction technique enabled us to identify and analyze theories used in BuS studies. This analysis revealed 150 underlying theories that advance the BuS concept across different research topics. The study contributes to BuS theory development with great potential to improve ethical decision-making by establishing meaningful, context-specific definitions and providing clear guidance for future researchers in selecting appropriate theoretical perspectives for their work. We identify research gaps, propose a prioritized research agenda focused on theory development, and formulate key implications for practitioners and policymakers. This study demonstrates the effectiveness of machine learning methods in conducting large-scale literature reviews to accelerate theoretical advancements and generate research agendas. (shrink)
A Path Analysis of Greenwashing in a Trust Crisis Among Chinese Energy Companies: The Role of Brand Legitimacy and Brand Loyalty.Rui Guo,Lan Tao,Caroline Bingxin Li &Tao Wang -2017 -Journal of Business Ethics 140 (3):523-536.detailsFor many energy companies in China, green brand strategy is becoming an important approach to enhance competitive advantage. However, greenwashing behaviors result in a crisis of trust. Existing research focuses on green marketing, but is silent on the institutional view of the trust crisis resulting from greenwashing by energy brands. Thus, this study takes a decoupling perspective from institutional theory and considers legitimacy, energy policy management, and green brand theories to shed light on the path from the decoupling of an (...) energy brand from green promise to green energy brand trust and the role of brand legitimacy and brand loyalty. It then analyzes survey data to conclude that DEBG not only has a direct negative effect on GEBT but also has an indirect influence through the vital mediating role of green energy brand legitimacy. Moreover, brand loyalty is a moderating factor and can alleviate the energy brand trust crisis. These findings not only can enrich the theories of energy brand management and green marketing but also offer important implications for energy policy management. (shrink)
Toward improving control performance of myoelectric arm prosthesis by adding wrist position feedback.Yue Zheng,Lan Tian,Xiangxin Li,Yingxiao Tan,Zijian Yang &Guanglin Li -2022 -Frontiers in Human Neuroscience 16.detailsWearing a myoelectric prosthesis is a basic way for limb amputees to restore their lost limb functions in the activities of daily living. However, it is estimated that around 40% of amputees refuse the prosthesis. One of the primary reasons would be that the current prostheses lack appropriate sensory feedback. Currently, the amputees only depend on their visual feedback when using their arm prostheses. It would be difficult for them to accurately control the wrist position, which is vital for flexible (...) manipulation in ADLs. This manuscript designed a myoelectric arm prosthesis with wrist position feedback. To study the effect level of position feedback on prosthetic control, two tests were performed. The vibrotactile perception range test aims to analyze the perception sensitivity of the vibration in humans and obtain the optimal perception range utilized in the sensory feedback test. The sensory feedback test analyzes the effectiveness of the position feedback by comparing three feedback methods of Vis-FB, WP-FB, and a combination of Vis-FB and WP-FB. These tests were conducted by asking six able-bodied subjects to perform 20 movement combinations of five target positions. The WP-FB was transiently activated with five vibrating motors embedded in an armband to stimulate the arm stump when the prosthetic wrist rotates to the target positions. Our experimental results showed that when WP-FB was added to the prosthetic control, the absolute angular error of the prosthetic wrist declined from 4.50° to 1.08° while the success rate 3 increased from 0.34 to 0.84, respectively. This study demonstrates the importance of WP-FB to the effective control of the arm prosthesis. (shrink)
Many hands make many fingers to point: challenges in creating accountable AI.Stephen C. Slota,Kenneth R. Fleischmann,Sherri Greenberg,Nitin Verma,Brenna Cummings,Lan Li &Chris Shenefiel -2023 -AI and Society 38 (4):1287-1299.detailsGiven the complexity of teams involved in creating AI-based systems, how can we understand who should be held accountable when they fail? This paper reports findings about accountable AI from 26 interviews conducted with stakeholders in AI drawn from the fields of AI research, law, and policy. Participants described the challenges presented by the distributed nature of how AI systems are designed, developed, deployed, and regulated. This distribution of agency, alongside existing mechanisms of accountability, responsibility, and liability, creates barriers for (...) effective accountable design. As agency is distributed across the socio-technical landscape of an AI system, users without deep knowledge of the operation of these systems become disempowered, unable to challenge or contest when it impacts their lives. In this context, accountability becomes a matter of building systems that can be challenged, interrogated, and, most importantly, adjusted in use to accommodate counter-intuitive results and unpredictable impacts. Thus, accountable system design can work to reconfigure socio-technical landscapes to protect the users of AI and to prevent unjust apportionment of risk. (shrink)
Effect of Serendipity in an Encounter on Purchase Intention of Unexpected Products.Shichang Liang,Yuxuan Chu,Min Zhang,Rulan Li,Bin Lan &Lingling He -2022 -Frontiers in Psychology 13.detailsPrevious studies on the follow-up effect of serendipity mostly focused on the positive effects and less on the negative effects. Therefore, the purpose of this article is to investigate the negative effect of serendipity on the purchase intention of unexpected products. To verify all hypotheses in this article, we used online and offline survey data in China. Three experimental results showed that serendipity contains a certain degree of uncertainty, which will cause consumers’ perceived risk and decrease the purchase intention of (...) unexpected products. Perceived risk plays a mediating role in the effect of serendipity on the purchase intention of unexpected products. Moreover, regulatory focus moderates the effect of serendipity on purchase intention of unexpected products. Specifically, for prevention-focused individuals, the negative effect of serendipity on the purchase intention of unexpected products is strengthened. For promotion-focused individuals, the negative effect of serendipity on the purchase intention of unexpected products is weakened. This article augments the understanding of the negative effects of serendipity and provides theoretical guidance and support for the management practice of marketers. (shrink)
The effect of i-deals on employees’ unethical behavior during the COVID-19 pandemic: The roles of hubristic pride and grandiose narcissism.Zhihao Liu,Xiaoyan Zhang,Hanzhi Xu,Hui Deng,Jiajia Li &Yuanyuan Lan -2022 -Frontiers in Psychology 13.detailsThe COVID-19 pandemic has created enormous challenges for organizations and employees. Due to the effectiveness of idiosyncratic deals in management practices, more and more organizations use this human resource management tool to address the challenges posed by the COVID-19 pandemic. However, whether there are potential risks or negative effects of i-deals in the COVID-19 pandemic environment is not very clear. Drawing upon social cognitive theory, we proposed that i-deals may foment focal employees’ unethical behavior by triggering their hubristic pride, and (...) such process may be moderated by their trait of grandiose narcissism. We conducted a survey during the COVID-19 outbreak and tested our hypotheses with 492 samples from Shandong Province, China. Consistent with predictions, we found a positive relationship between i-deals and hubristic pride, which, in turn, increased their unethical behavior. And the relationship between i-deals and unethical behavior was mediated by hubristic pride. Furthermore, grandiose narcissism strengthened the positive relationship between i-deals and hubristic pride, as well as the indirect effect of i-deals on unethical behavior via hubristic pride. Our findings contributed to the literature on i-deals and provided guidance for organizations to address the challenges posed by the COVID-19 pandemic. (shrink)
Can empowering leadership promote employees’ pro-environmental behavior? Empirical analysis based on psychological distance.Ting Yue,Chenchen Gao,Feiyu Chen,Lan Zhang &Mengting Li -2022 -Frontiers in Psychology 13.detailsLeadership styles, especially empowering leadership, affect the psychological relationship between employees and organizations, and then affect employees’ positive behavior in the organization. In this research, we studied the effects of empowering leadership and psychological distance on employees’ pro-environmental behavior and explored the mechanism of green organizational climate. By adopting correlation analysis, statistical analysis, and regression analysis, we conducted a multisource field study of 873 valid employee questionnaires to verify our theoretical model. The results showed that empowering leadership had a significant (...) positive impact on psychological distance and employees’ pro-environmental behavior; and psychological distance played a partly intermediation role in the relationship between empowering leadership and employees’ pro-environmental behavior. Moreover, GOC can promote employees’ pro-environmental behavior, but it cannot regulate between psychological distance and employees’ pro-environmental behavior. The findings obtained some intriguing insights that could help to better guide employees toward pro-environmental behavior. (shrink)
