摘要： 数字化转型是企业实现创新的重要路径,然而将数字化理论与知识管理理论相结合,探讨其对企业创新绩效影响的研究较匮乏。提出知识数字化概念,通过建立有调节的中介模型,基于中国243家企业调研数据,进行多元线性回归以及结构方程模型分析,探究企业知识数字化对创新绩效的影响,以及研发探索能力的中介作用和企业家导向的调节作用。结果表明:企业知识数字化对创新绩效具有显著正向影响,研发探索能力在此过程中发挥部分中介作用,且该作用受到企业家导向的正向调节,即企业家导向会强化研发探索能力的中介作用。研究结论扩展了数字技术对知识管理影响的研究视角,可为企业进行知识数字化转型、提升创新绩效提供实践参考。

摘要： A wide range of etiologies, both ischemic and nonischemic, can produce an electrocardiographic pattern of ST-segment elevation (STE), including Takotsubo syndrome (TTS) and electrolyte imbalances. Instances of hypocalcemia-induced TTS and STE are exceedingly rare in medical literature. This paper presents the case of a 75-year-old woman with advanced ovarian cancer and no prior heart issues, who exhibited diffuse STE on electrocardiogram, resembling acute coronary syndrome. Additionally, echocardiography suggested left ventricle apical ballooning, as per TTS, in the context of severe hypocalcemia and elevated troponin I level. After confirming no coronary artery disease via angiography, we administered calcium supplementation. Subsequently, the electrocardiogram displayed widespread giant T-wave inversions, and the patient's cardiac function fully recovered on normalization of calcium levels within few days. This case serves to highlight the importance of recognizing rare causes of STE (eg, hypocalcemia-induced cardiomyopathy), particularly in patients with neoplastic condition. However, the precise mechanism underlying a potential hypocalcemia-induced TTS remains to be elucidated, and there are only a limited number of case reports in the literature. In light of the aforementioned considerations, we propose a comprehensive examination of cases associated with hypocalcemia and STE and left ventricular systolic impairment. © 2024 The Authors

摘要： Primary cardiac angiosarcomas are rare malignant tumors that can cause chest pain and heart failure symptoms. They can be diagnosed using multimodality imaging, primarily echocardiogram, with formal diagnosis requiring biopsy. A 56-year-old man with history of hypertension and dyslipidemia presented with acute crushing chest pain and shortness of breath. Electrocardiogram showed diffuse ST-segment elevations. Urgent coronary angiography revealed no significant coronary disease but found delayed contrast filling from the left coronary artery to a structure overlying the right atrium with further work-up revealing primary cardiac angiosarcoma. This case represents a unique scenario in which primary cardiac angiosarcoma was discovered from coronary angiography. Clinicians should prioritize and rule out life-threatening emergencies but should recognize the utility of angiography in elucidating other etiologies of chest pain (eg, angiosarcoma). Finally, early screening for metastatic disease should be completed to identify alternative potential biopsy targets. © 2024 The Authors

摘要： In the 21st century, traditional lecture-based teaching methods are being increasingly supplemented by interactive and student-centered approaches to enhance student engagement and learning outcomes. This Matter of Opinion explores the use of active learning groups, which were developed by Prof. Billinge as an effective pedagogical tool in materials science and engineering courses.

摘要： Purpose Key pharmacotherapeutic modalities and considerations for the patient with ST-elevation myocardial infarction (STEMI) across the critical initial phases of care are *** Despite established value in the emergency department (ED), cardiac care, and intensive care settings, there is currently little published literature describing or supporting clinical pharmacist roles in the acute management of STEMI. The high-risk period from hospital presentation through revascularization and stabilization involves complex pharmacotherapeutic decision points, many operational medication needs, and multiple layers of quality oversight. While rife with opportunities for pharmacists to optimize care, this timeframe appears inconsistently targeted by clinical pharmacy services, which may halt after ED evaluation and then resume upon postcatheterization cardiac unit admission. Herein we review the key pharmacotherapeutic modalities and considerations for the patient with STEMI across the critical initial phases of care. These include supportive therapies prior to revascularization, the host of antithrombotics involved in revascularization by percutaneous coronary intervention and/or fibrinolysis, and other periprocedural medications. Important practice guidelines and clinical resources are summarized from the clinical pharmacist perspective, and roles and responsibilities of the responding pharmacist are suggested. A companion article will extend the review to periprocedural adverse event management, key early decision-making regarding long-term risk reduction, and pharmacist involvement in institutional quality improvement efforts. We aim to support inpatient pharmacy departments in advancing clinical services for this critical patient population, and we call for further research delineating pharmacist impact on patient and institutional STEMI *** Patients presenting with STEMI rapidly traverse multiple phases of care and receive a host of antithrom

摘要： Purpose This study aims to explore the intersection of English and education through a systematic review of academic literature. It focuses on identifying key research themes and future research areas, particularly in sustainable teaching and learning practices within the field of English education. Design/methodology/approach This study analyzed 84 papers published between May 2000 and May 2024 using a bibliometric approach. Keyword co-occurrence analysis was used to identify clusters of research themes. These clusters helped in categorizing research areas and provided a systematic overview of the current literature in English education. Findings This study identified four distinct research clusters that represent core themes in English education research. These themes informed the development of a research agenda focusing on areas that require further exploration, particularly in sustainable teaching and learning practices. This study also examined the theoretical and practical implications of these themes. Practical implications The findings provide educators and policymakers with a framework to prioritize research efforts, allocate resources and develop strategies to enhance sustainable teaching and learning practices in English education. Social implications By emphasizing the importance of sustainability in teaching and learning, this study promotes educational practices that contribute to long-term improvements in both student outcomes and teacher development. It identifies opportunities for sustainable growth in English education that benefit diverse learners. Originality/value To the best of the author's knowledge, this is the first study to apply a bibliometric approach to systematically review the intersection of English and education. By identifying core research clusters and creating a research agenda, this study contributes new insights into sustainable practices in English education.
