个体化延续护理对人工全髋关节置换术患者康复情况的研究

探讨个体化延续护理服务对人工全髋关节臵换术患者康复情况及自理能力恢复的影响。选取行人工全髋关节臵换术患者60例作为研究对象,随机分为对照组30例,观察组30例,对照组给予常规的出院护理指导,观察组给予延续护理服务,通过Harris评分、Barthel指数评分对患者康复情况进行评价。观察组出院后1个月、3个月Harris评分、Bathel指数评分明显高于对照组(P<0.05)。个体化延续护理服务可以促进人工全髋关节臵换术患者的康复,改善其生活质量。

一个永葆青春的研究传统——试论中国特色社会主义理论体系的“自然发展”

中国特色社会主义理论体系的“自然发展”,包括邓小平理论对毛泽东思想的“自然发展”、“三个代表”重要思想对邓小平理论的自然发展以及科学发展观对“三个代表”重要思想的“自然发展”。“自然发展”有连续性、类似性、灵活性三种理论形态。连续性即直接的继承关系;类似性即间接的继承关系;灵活性即创新与发展。     

Banach空间中一类广义混合平衡问题系统解的存在性及算法

在实Banach空间中引入和研究了一类新的广义混合平衡问题组.首先考虑了一个辅助混合平衡问题组,通过它与广义混合平衡问题组的等价性,证明了它的解的存在性和唯一性;其次构造了广义混合平衡问题组的近似解的迭代算法.在一定的条件下,证明了由算法生成的迭代序列的强收敛性,这些结果推广并改进了近期的某些结果.     

Business continuity of business models: Evaluating the resilience of business models for contingencies

Company business models are vulnerable to various contingencies in the business environment that may unexpectedly render their business logic ineffective. In particular, technological advancements, such as the Internet of things, big data, sharing economy and crowdsourcing, have enabled new forms of business models that can effectively and abruptly make traditional business models obsolete. By disrupting or even diminishing companies’ revenue streams, environmental contingencies may present a significant threat to business continuity (BC). Evaluating the resilience of business models against these contingencies should therefore be a core area of BC. However, existing BC approaches tend to focus on the continuity of the resources and processes through which a particular business model is accomplished in practice but omit the business model itself. We argue that in order for BC approaches to become holistic and strategic, business models need to become a part of the BC considerations, entailing an expansion of the scope of BC from value preservation to value creation. We propose an approach of Strategic Business Continuity Management, which consists of two parts: (1) sustaining the continuity of the company business model (value preservation) and (2) evaluating and modifying the business model (value creation). We illustrate conceptually the value creation part with an example drawn from the sharing economy.     

An analysis of the reach and effectiveness of distance learning in India during school closures due to COVID-19

In India, more than 276 million children and youth were out of school for extended periods since March 2020 due to school closures in response to COVID-19. A key challenge has been how to measure the impact of responses to continuity of learning both to ensure more effective responses in the event of further disruptions, but also to help the education community conceptualize more creative and effective approaches to learning, through blended and flexible approaches. This study reflects on the findings from a UNICEF survey targeting parents and adolescents across 6 states in India, and identifies lessons learned for addressing learning inequities during future school closures. We focus on measuring three key variables – access to technology, their utilization, and perceived learning for different profiles of children. As students began learning from home, technology access rates in households were initially used to determine the estimated maximum reach of different distance learning modalities during school closures. Beyond access, we find significant variations in adolescents’ use of technology for learning purposes and their perceptions of learning, linked to the type of remote learning modality, gender, location and type of school. We discuss the implications for government strategies and policies to ensure better utilization of technologies which are available in households and to address equity gaps in learning opportunities.
