数字化学习能力是助推高职学生适应数字化学习、提升学习效果的必要条件,是促进学生终身学习、把握未来发展主动权的核心素养。为客观认识高职学生数字化学习能力现状,采用问卷调查法,从学习意识、学习技术、学习行为、学习管理、学习评价等层面对高职学生的数字化学习能力展开量化分析。结果表明,学生习惯于进行数字化学习,但多为被动参与;数字化学习工具应用能力有待提升;信息加工与知识共享能力偏弱;注意力失焦问题频发;对学习过程的主动反思和调节较少。为提升高职学生的数字化学习能力,应当搭建优质的数字化学习空间,重视培养学生的元认知策略和批判性思维,让教师成为数字化学习的“导航”者,构建横向融合、纵向衔接的数字化学习能力培养体系。

目的:分析127例非小细胞肺癌(non-small cell lung cancer, NSCLC)免疫治疗药物不良反应(adverse reaction, ADR)的发生特点及临床表现,为临床及时发现和控制用药安全风险提供依据。方法:提取医院2019年7月—2023年5月住院患者免疫治疗的127例NSCLC的ADR发生情况,并按照患者的性别和年龄、ADR累及的器官/系统及临床表现、引起ADR用药亚组等维度进行统计及复杂网络分析。结果:127例患者中,有114例患者发生ADR,其中男性患者91例,占比79.82%,60~74岁年龄组ADR患者最多,共50例(43.86%);ADR以消化系统、血液/淋巴系统的损害最为多见,恶心55例、呕吐53例、骨髓抑制48例。结论:60岁以上NSCLC患者在接受免疫治疗时发生ADR事件概率高,尤其是消化系统和血液/淋巴系统,由于血液/淋巴系统ADR对疾病疗效影响较大,临床应重点监测血液/淋巴系统ADR。

We introduce notions of continuous orbit equivalence and its one-sided version for countable left Ore semigroup actions on compact spaces by surjective local homeomorphisms,and characterize them in terms of the corresponding transformation groupoids and their operator *** particular,we show that two essentially free semigroup actions on totally disconnected compact spaces are continuously orbit equivalent if and only if there is a canonical abelian subalgebra preserving C^(∗)-isomorphism between the associated transformation groupoid C^(∗)-*** also give some examples of orbit equivalence,consider the special case of semigroup actions by homeomorphisms and relate continuous orbit equivalence of semigroup actions to that of the associated group actions.
