Crowd counting has important applications in public safety and pandemic control.A robust and practical crowd counting system has to be capable of continuously learning with the newly incoming domain data in real-world scenarios instead of fitting one domain only.Off-the-shelf methods have some drawbacks when handling multiple domains:(1)the models will achieve limited performance(even drop dramatically)among old domains after training images from new domains due to the discrepancies in intrinsic data distributions from various domains,which is called catastrophic forgetting;(2)the well-trained model in a specific domain achieves imperfect performance among other unseen domains because of domain shift;(3)it leads to linearly increasing storage overhead,either mixing all the data for training or simply training dozens of separate models for different domains when new ones are available.To overcome these issues,we investigate a new crowd counting task in incremental domain training setting called lifelong crowd counting.Its goal is to alleviate catastrophic forgetting and improve the generalization ability using a single model updated by the incremental domains.Specifically,we propose a self-distillation learning framework as a benchmark(forget less,count better,or FLCB)for lifelong crowd counting,which helps the model leverage previous meaningful knowledge in a sustainable manner for better crowd counting to mitigate the forgetting when new data arrive.A new quantitative metric,normalized Backward Transfer(nBwT),is developed to evaluate the forgetting degree of the model in the lifelong learning process.Extensive experimental results demonstrate the superiority of our proposed benchmark in achieving a low catastrophic forgetting degree and strong generalization ability.

The urban grass-roots library is an important part of the public cultural service system,and also a place to carry out national reading and lifelong learning,which is of great significance to the construction of a learning society.In this paper,the development and evolution of urban grassroots libraries in China are reviewed,and the current situation and usage issues of grassroots libraries in Beijing are analyzed.Moreover,the development strategy of idea stores in London,UK is studied,and characteristics are summarized,and possible references are sought.In the new era,urban grassroots libraries should integrate into communities with multiple functions and play a more sufficient role in public education,learning and training,and other aspects.

With the rapid advancements in technology,especially in digitalization and intelligence,numerous modern technologies have poured into rural schools,effectively improving their informatization conditions.Nevertheless,these technologies remain detached from rural teachers,failing to significantly enhance the quality of education and teaching in rural areas.Rural education is a crucial aspect of ensuring balanced development in education.The question of how to enhance rural teachers’technological application abilities and fully leverage the positive role of technology in rural education and teaching has become a significant topic of current research on rural education issues.To better address this question,this study conducted a thorough examination of the specific appeals of rural teachers in the process of technology enablement.It was discovered that rural teachers generally face dilemmas such as insufficient technological application abilities,difficulties in obtaining quality teaching resources,and the lack of continuous technical support and update mechanisms.Based on these findings,specific pathways such as strengthening rural teacher training,optimizing the allocation of educational resources,and establishing mechanisms for continuous technical support and updates are proposed to aid in the high-quality development of rural education.

A landmark in the realization of UNESCO’s Sustainability Goals,Education for All(SDG4),was passed when the organization’s Recommendation of Open Educational Resources(OER)was uniformly adopted in 2019.Now it is time to transfer from the consciousness of OER to their mainstream realization at all levels,micro,meso,and macro,including all stakeholders,such as governments,institutions,academics,teachers,administrators,librarians,students,learners,and the civil service.The OER Recommendation includes five areas:building capacity and utilizing OER;developing supportive policies;ensuring effectiveness;promoting the creation of sustainable OER models;promoting and facilitating international collaboration;monitoring and evaluation.OER are valued as a catalyst for innovation and the achievement of UNESCO’s SDG 4,education for all,lifelong learning,social justice,and human rights.The OER Recommendation will be a catalyst for the realization of several other SDGs.Because access to quality OER concerns human rights and social justice,this Recommendation is vital.In 2020,the effects of the worldwide COVID-19 pandemic clearly demonstrated the importance of opening up education and the access to internationally recognized,qualified learning resources.This article describes and discusses how the promise of resilient,sustainable quality open education can be fulfilled in the new normal and the next normal.

德国低成就青年职业教育排斥探究

保障职业教育“参与率”和“含金量”，对我国职业教育振兴与整体发展具有至关重要的作用。德国职业教育培训体系虽享誉全球，但多数低成就青年却被“双元制”或“全日制”职业教育排斥而在“过渡制”职业培训与失业之间摇摆。究其原因，德国中等学校教育融通性不足，低成就青年面临前兆性职业教育边缘化风险；职业教育系统结构性歧视进一步阻碍低成就青年参与职业教育，并且引导其自我规训甚至“自我污名”；现代社会性风险又加剧群体负面反噬，增加了低成就青年自损性风险，导致其丧失优质职业教育机会。而德国深化中等学校体制改革、提高职业教育培训体系渗透性、运用财政金融杠杆保障教育参与以及提供终身化职业咨询服务等应对举措则启示我们着力构建职业学校(教育)价值认同，继续深化赋能弱势群体的职业教育改革；健全技能型人才培养的完整通道，赋予职业学校学生融合参与、多元发展、优质发展空间；增强技能体系与服务全民终身学习教育体系的黏合度，实现职业教育“阶段性”向“终身化”迈进。

作者： Jingyuan Zhao Andrew F.Burke Institute of Transportation Studies University of California DavisDavisCA 95616USA

Transportation electrification is essential for decarbonizing transport. Currently, lithium-ion batteries are the primary power source for electric vehicles (EVs). However, there is still a significant journey ahead before EVs can establish themselves as the dominant force in the global automotive market. Concerns such as range anxiety, battery aging, and safety issues remain significant challenges.

Knowledge entrepreneurship is increasingly becoming important in driving innovation for high levels of competitiveness.The purpose of this study was to investigate the relationship between Organization learning(OL)and Innovation Output(IO)for improved performance in manufacturing firms in Kenya.The theoretical underpinnings on this study are the Schumpeter’s(1934)innovation theory of and the Gleick(1987)complexity theory.The methodology used was mixed method research because it provides a more holistic understanding of a thematic area.The research design that was used is cross-sectional design because it allows for making observations on different characteristics that exist within a group at a particular time.The target population was manufacturing firms across the country.Multi-stage sampling strategy was used to sample 303 respondents from 101 firms.Primary and secondary data were used to collect both qualitative and quantitative data.The questionnaire,interview schedule and a checklist of key informants were used to collect data.Content validity was used to ascertain the credibility of the research procedure and internal consistency technique was used to test for reliability.Correlation and linear regression were used to determine the relationship between OL and IO.Work disruptions were avoided by making prior arrangements and appointments.The findings indicate that OL has a significant influence on IO.It is recommended that lifelong learning,management support and risk tolerance should be encouraged to improve creativity.High creativity is important in raising the capacity to integrate internal and external knowledge for greater levels of IO.Further research should be carried out to find how customers and suppliers information can be utilized to enriched OL.
