Objective: This meta-analysis evaluated the efficacy of acupuncture in improving cognitive impairment of post-stroke patients.Design: Randomized controlled trials investigating the effects of acupuncture compared with no treatment or sham acupuncture on post-stroke cognitive impairment before December 2019 were identified from databases. The literature searching and data extracting were independently performed by two investigators. Study quality was assessed using the Cochrane Handbook for Systematic Reviews of Interventions. Meta-analyses were performed for the eligible RCTs with Revman 5.3 software.Results: Thirty-seven RCTs were included in this meta-analysis. Merged Random-effects estimates of the gain of MMSE or MoCA were calculated for the comparison of acupuncture with no acupuncture or sham acupuncture. Following 2–8 weeks of intervention with acupuncture, pooled results demonstrated significant effects of acupuncture in improving PSCI assessed by MMSE or MoCA.Conclusion: The results suggest that acupuncture was effective in improving PSCI and supported the needs of more rigorous design with large-scale randomized clinical trials to determine its therapeutic benefits.

The evolution of Web 2.0 and social networks has led to the increased use of enterprise social media platforms, making online interactions more common in organizations. However, few studies have researched online interactions in organizational context. This study addressed this gap using two research phases: a qualitative phase and a quantitative phase. The qualitative study phase identified two dimensions of online interaction: employee–employee online interaction and employee–platform online interaction. The employee–employee online interaction assessed responsiveness and suitability. The employee–platform online interaction assessed usefulness, applicability, and ease of use. The quantitative study phase applied a proposed conceptual framework derived from the qualitative study to create and validate measures for a new online interaction scale. This was done using a systematic scale development process. Measuring online interaction can help drive future quantitative research, providing an instrumental basis for further exploring the scientific management practice elements that govern employee psychology and behavior in cyberspace.

Marxist Historiographies is the first book to examine the ebb and flow of Marxist historiography from a global and cross-cultural perspective. Since the eighteenth century, few schools of historical thought have exerted a more lasting impact than Marxism, and this impact extends far beyond the Western world within which it is most commonly analysed. Edited by two highly respected authors in the field and taking a truly global perspective on this topic, Marxist Historiographies demonstrates clearly the breadth and depth of Marxism's influence in historical writing throughout the world and is essential reading for all students of historiography.

In the May Fourth era of the 1910s and 1920s, Confucius' image was associated closely with the conservative political forces that were increasingly regarded by many as the cause of the challenges the newly founded Republic was facing. With respect to Confucius, Hu Shi believed that the critical attitude engendered in the May Fourth era had brought Confucius down from a high pedestal and put him on a par with the contemporaries of his time. Hu Shi's main assessment of Confucius as an ancient philosopher was shown in his doctoral dissertation and the later published A History of Ancient Chinese Philosophy, both appeared in the May Fourth era. During the May Fourth era, the interest in distinguishing “historical Confucius” from “iconic Confucius” was conducive to the emergence of the National Studies Movement, led by Zhang Taiyan, Hu Shi, Liang Qichao, and others.

Aiming at suppressing harmful effect for building structure by surface motion, semiactive nonsmooth control algorithm with Deep Learning is proposed. By finite-time stable theory, the building structure closed-loop system’s stability is discussed under the proposed control algorithm. It is found that the building structure closed-loop system is stable. Then the proposed control algorithm is applied on controlling the building structural vibration. The seismic action is chosen as El Centro seismic wave. Dynamic characteristics have comparative analysis between semiactive nonsmooth control and passive control in two simulation examples. They demonstrate that the designed control algorithm has great robustness and anti-interference. The proposed control algorithm is more effective than passive control in suppressing structural vibration.

This paper aims to study the determinants of subjective happiness among working females with a focus on female managers. Drawn on a large social survey data set in China, this paper constructs gender development index at sub-national levels to study how institutional settings are related to female managers’ happiness. We find that female managers report higher levels of happiness than non-managerial employees. However, the promoting effect is contingent on individual characteristics and social-economic settings. The full sample regression suggests that female managers behaving in a masculine way generally report a high level of happiness. Meanwhile, female managers who refuse to support gender equality report low happiness levels. Sub-sample analysis reveals that these causalities are conditioned on regional culture. Masculine behavior and gender role orientation significantly predict subjective happiness only in gender-egalitarian regions. This study is one of the first to consider both internal and external factors when investigating how female managers’ happiness is impacted. Also, this study challenges the traditional wisdom on the relationship between female managers’ job satisfaction and work-home conflict. This study extends the literature by investigating the impacts of female managers’ masculine behavior on their happiness. This study is useful for promoting female managers’ leadership effectiveness and happiness.

This study adopted a positive psychology perspective to investigate positive emotion and foreign language enjoyment among Chinese as a second language learners in an emergency remote teaching context amid the COVID-19 pandemic. A set of 90 preparatory Chinese language students was assessed for their level of foreign language enjoyment using the Foreign Language Enjoyment Scale. Participles' scores on self-perceived language achievement and actual test scores were adopted as the measurement of their Chinese language proficiency. The results revealed that: CSL learners experienced high level of FL enjoyment in an online learning context, no significant correlation was found between FLE and leaners' actual language achievement nor between FLE and their self-perceived achievement, female learners showed higher FLE than male learners and gender was found to have a significant effect on FLE-Private, participants' geological location, i.e., whether in China or at home countries, significantly influenced their FLE, participants' regional group was not a significant predictor of FLE, and teacher-related variables and learner self-perceptions of achievement were strong predictors of FLE among CSL learners. The findings highlight the importance of teacher's role in an online learning environment and suggest that FLE may not boost performance in the short term for language beginners but is still conducive in the long run. Implications for both teachers and learners, and suggestions for future researches are provided.

In correlated electron materials, electrons often self-organize and form a variety of patterns with potential ordering of charges, spins, and orbitals, which are believed to be closely connected to many novel properties of these materials including superconductivity, metal-insulator transitions, and the CMR effect. How these real-space patterns affect the conductivity and other properties of materials is one of the major challenges of modern condensed matter physics. Moreover, although the presence of static stripes is indisputable, the existence of fluctuating stripes in such compounds is a subject of great debate. Here we present the electronic excitations of La$_{2-2x}$Sr$_{1+2x}$Mn$_{2}$O$_{7}$ probed by angle-resolved photoemission, from which we demonstrate that a novel type of ordering, termed bi-stripes, can exhibit either static or fluctuating order as a function of temperature. We found that the static bi-stripe order is especially damaging to electrical conductivity, completely localizing the electrons in the bi-stripe regions, while the fluctuating stripes can coexist with mobile carriers. This physics drives a novel phase transition with colossal conductivity changes as a function of temperature. Our finding suggests that quantum stripes can give rise to electronic properties significantly different from their static counterparts. Inducing transition between them can turn on remarkable electronic phenomena, enriching our understanding of correlated electron systems as well as opening a window for potential applications in electronic devices.

© 2015 Elsevier Inc. β-adrenergic signaling pathways mediate key aspects of cardiac function. Its dysregulation is associated with a range of cardiac diseases, including dilated cardiomyopathy. Previously, we established an iPSC model of familial DCM from patients with a mutation in TNNT2, a sarcomeric protein. Here, we found that the β-adrenergic agonist isoproterenol induced mature β-adrenergic signaling in iPSC-derived cardiomyocytes but that this pathway was blunted in DCM iPSC-CMs. Although expression levels of several β-adrenergic signaling components were unaltered between control and DCM iPSC-CMs, we found that phosphodiesterases 2A and PDE3A were upregulated in DCM iPSC-CMs and that PDE2A was also upregulated in DCM patient tissue. We further discovered increased nuclear localization of mutant TNNT2 and epigenetic modifications of PDE genes in both DCM iPSC-CMs and patient tissue. Notably, pharmacologic inhibition of PDE2A and PDE3A restored cAMP levels and ameliorated the impaired β-adrenergic signaling of DCM iPSC-CMs, suggesting therapeutic potential. In this paper, Wu etal. profiled the β-adrenergic signaling properties in human iPSC-CMs and demonstrated novel epigenetic mechanisms that underlie the compromised β-adrenergic signaling in DCM, a common cause of heart failure and cardiac transplantation. These results enhance our understanding of DCM pathogenesis and may uncover new therapeutic targets.
