    微生物的分布和对人类功能和福祉的影响都很普遍,一般生命和地球。基于微生物的技术为我们依赖的重要商品和服务的供应做出了巨大贡献。例如提供食物,药品和干净的水。它们还提供了机制和战略,以减轻和解决人类各级面临的广泛问题和危机,包括联合国制定的可持续发展目标(SDG)中包含的目标。例如,微生物技术可以通过多种方式促进脱碳,从而应对全球变暖,为数十亿缺乏卫生和清洁水的人提供卫生和清洁水,改善土壤肥力,从而提高粮食生产,并开发疫苗和其他药物,以减少并在某些情况下消除致命的感染。它们是生物技术的基础,一个日益重要和不断增长的商业部门和就业来源,和生物经济的中心,绿色交易,等。但是,因为微生物基本上是看不见的,他们对大多数人来说并不熟悉,因此,决策者往往会错过他们提供的有效预防和解决问题的机会,带来的负面影响。为了纠正这种缺乏重要知识的情况,国际微生物学扫盲倡议-IMiLI-正在从全球微生物学界招募并免费提供,社会相关微生物学课程的教学资源,可用于各级学习。它的目标是发展一个有相关微生物学知识的社会,因此,能够充分利用微生物的潜力,并最大限度地减少其负面活动的后果。除了教授微生物,几乎每堂课都讨论了他们对可持续性和可持续发展目标的影响,以及他们解决社会不平等紧迫问题的能力。因此,课程教授可持续性,社会需求和全球公民身份。这些课程还揭示了微生物及其活动对我们个人日常生活的影响,家庭,社区,国家和全球层面及其与各级决策的相关性。And,因为有效,基于证据的决策不仅需要相关信息,还需要批判性和系统思维,这些资源还教授了审议的这些关键通用方面。IMiLI教学资源以学习者为中心,不以学术微生物学为中心,处理日常问题的微生物学。这些话题涵盖了拥有和照顾伴侣动物等各种主题,通过微生物过程生产的各种日常食品,由微生物创造的令人印象深刻的地质构造,儿童疾病以及如何管理以及如何减少浪费和污染。他们还利用探索和发现的非凡兴奋,这些探索和发现代表了微生物学的巨大进步,以吸引人们的兴趣,激励和激励教育者和学习者。IMiLI正在建立区域中心,以将教学资源翻译成区域语言并使其适应区域文化,并促进它们的使用,并协助教育工作者使用它们。其中两个现已开始运作。区域中心构成了资源创造者和教育者-学习者之间的接口。因此,他们将收集和分析最终用户的反馈,并将其传输给资源创建者,以便可以改进和完善教材,以及响应需求而增加的新资源:教育者和学习者将因此直接参与教学资源的演变。由区域中心介导的教育者-学习者和资源创造者之间的互动将建立动态和协同的关系-一个全球社会相关的微生物学教育生态系统-其中创造者也成为学习者,教学资源得到优化,所有参与者/利益相关者都得到了授权,他们的动机也得到了提高。因此,IMiLI概念包含了在更广泛的社会背景下教授社会相关微生物学的原则,生物圈和行星的需求,不平等,我们面临的危机范围以及改进决策的必要性,这将最终导致更好的公民身份和更可持续和有弹性的人类。
    地球的生物圈是一个微生物世界:无数微生物驱动的化学转化和能量转移的巨大反应器,推动和拉动许多行星地球化学过程,包括生命元素的循环,缓解或扩大气候变化(例如,自然评论微生物学,2019,17,569)并影响所有生物体的福祉和活动,包括人类。微生物既是我们的祖先,也是使我们能够进化的行星化学的创造者(例如,生命引擎:微生物如何使地球适合居住,2023年)。为了了解生物圈的功能,人类如何影响它的发展,并与其他共享它的生物更可持续地生活,我们需要了解微生物。在最近的一篇社论(环境微生物学,2019、21、1513),我们提倡提高社会的微生物学素养。我们的微生物学素养概念不是基于微生物学学科的知识,凭借其众多的组件主题,加上来自其他学科的越来越多的额外主题,这些主题成为当前微生物学中至关重要的元素。相反,它侧重于影响我们个人/社区/国家/人类世界和生物圈的微生物活动,这些活动对于就我们经常面临的许多问题做出明智的决定至关重要,从个人问题到具有全球重要性的危机。换句话说,它是对成年和向成年过渡至关重要的知识和理解,必须在学校早期获得的知识和理解。2019年社论标志着国际微生物学素养倡议的启动,IMILI.在这里,我们呈现:我们关于如何实现微生物学素养的概念以及支撑它的基本原理;在可持续性的背景下,为实现这些资源中处理的微生物活动的概念和框架而创建的教学资源类型,社会需求和责任以及决策;以及将把教学资源翻译成当地语言的区域中心的关键作用,根据当地文化需求进行调整,与区域教育工作者的接口,并发展和充当微生物学素养教育网络的枢纽。教学资源中的主题以学习者为中心,并因其固有的相关性而被选中,激发和参与的兴趣和能力。重要的是,资源连贯地整合和强调可持续性的总体问题,管理和批判性思维以及过程的普遍相互依存。更广泛地说,该概念强调如何利用微生物活动的多种应用来促进人类/动物,植物,环境和行星健康,改善社会公平,减轻人道主义赤字和人民之间冲突的原因,并增进人民之间的理解(微生物生物技术,2023年,16(6),1091-1111)。重要的是,尽管免费提供(CCBY-NC4.0)IMiLI教学资源的主要目标是学童及其教育者,它们和教学理念适用于所有年龄段,全球学习者的能力和文化光谱:在大学教育中,终身学习,好奇心驱动,基于网络的知识获取和公共宣传。IMiLI教学资源旨在促进全球微生物学教育生态系统的发展,使微生物学知识民主化。
    UNASSIGNED: Microbes are all pervasive in their distribution and influence on the functioning and well-being of humans, life in general and the planet. Microbially-based technologies contribute hugely to the supply of important goods and services we depend upon, such as the provision of food, medicines and clean water. They also offer mechanisms and strategies to mitigate and solve a wide range of problems and crises facing humanity at all levels, including those encapsulated in the sustainable development goals (SDGs) formulated by the United Nations. For example, microbial technologies can contribute in multiple ways to decarbonisation and hence confronting global warming, provide sanitation and clean water to the billions of people lacking them, improve soil fertility and hence food production and develop vaccines and other medicines to reduce and in some cases eliminate deadly infections. They are the foundation of biotechnology, an increasingly important and growing business sector and source of employment, and the centre of the bioeconomy, Green Deal, etc. But, because microbes are largely invisible, they are not familiar to most people, so opportunities they offer to effectively prevent and solve problems are often missed by decision-makers, with the negative consequences this entrains. To correct this lack of vital knowledge, the International Microbiology Literacy Initiative-the IMiLI-is recruiting from the global microbiology community and making freely available, teaching resources for a curriculum in societally relevant microbiology that can be used at all levels of learning. Its goal is the development of a society that is literate in relevant microbiology and, as a consequence, able to take full advantage of the potential of microbes and minimise the consequences of their negative activities. In addition to teaching about microbes, almost every lesson discusses the influence they have on sustainability and the SDGs and their ability to solve pressing problems of societal inequalities. The curriculum thus teaches about sustainability, societal needs and global citizenship. The lessons also reveal the impacts microbes and their activities have on our daily lives at the personal, family, community, national and global levels and their relevance for decisions at all levels. And, because effective, evidence-based decisions require not only relevant information but also critical and systems thinking, the resources also teach about these key generic aspects of deliberation. The IMiLI teaching resources are learner-centric, not academic microbiology-centric and deal with the microbiology of everyday issues. These span topics as diverse as owning and caring for a companion animal, the vast range of everyday foods that are produced via microbial processes, impressive geological formations created by microbes, childhood illnesses and how they are managed and how to reduce waste and pollution. They also leverage the exceptional excitement of exploration and discovery that typifies much progress in microbiology to capture the interest, inspire and motivate educators and learners alike. The IMiLI is establishing Regional Centres to translate the teaching resources into regional languages and adapt them to regional cultures, and to promote their use and assist educators employing them. Two of these are now operational. The Regional Centres constitute the interface between resource creators and educators-learners. As such, they will collect and analyse feedback from the end-users and transmit this to the resource creators so that teaching materials can be improved and refined, and new resources added in response to demand: educators and learners will thereby be directly involved in evolution of the teaching resources. The interactions between educators-learners and resource creators mediated by the Regional Centres will establish dynamic and synergistic relationships-a global societally relevant microbiology education ecosystem-in which creators also become learners, teaching resources are optimised and all players/stakeholders are empowered and their motivation increased. The IMiLI concept thus embraces the principle of teaching societally relevant microbiology embedded in the wider context of societal, biosphere and planetary needs, inequalities, the range of crises that confront us and the need for improved decisioning, which should ultimately lead to better citizenship and a humanity that is more sustainable and resilient.
    UNASSIGNED: The biosphere of planet Earth is a microbial world: a vast reactor of countless microbially driven chemical transformations and energy transfers that push and pull many planetary geochemical processes, including the cycling of the elements of life, mitigate or amplify climate change (e.g., Nature Reviews Microbiology, 2019, 17, 569) and impact the well-being and activities of all organisms, including humans. Microbes are both our ancestors and creators of the planetary chemistry that allowed us to evolve (e.g., Life\'s engines: How microbes made earth habitable, 2023). To understand how the biosphere functions, how humans can influence its development and live more sustainably with the other organisms sharing it, we need to understand the microbes. In a recent editorial (Environmental Microbiology, 2019, 21, 1513), we advocated for improved microbiology literacy in society. Our concept of microbiology literacy is not based on knowledge of the academic subject of microbiology, with its multitude of component topics, plus the growing number of additional topics from other disciplines that become vitally important elements of current microbiology. Rather it is focused on microbial activities that impact us-individuals/communities/nations/the human world-and the biosphere and that are key to reaching informed decisions on a multitude of issues that regularly confront us, ranging from personal issues to crises of global importance. In other words, it is knowledge and understanding essential for adulthood and the transition to it, knowledge and understanding that must be acquired early in life in school. The 2019 Editorial marked the launch of the International Microbiology Literacy Initiative, the IMiLI. HERE, WE PRESENT: our concept of how microbiology literacy may be achieved and the rationale underpinning it; the type of teaching resources being created to realise the concept and the framing of microbial activities treated in these resources in the context of sustainability, societal needs and responsibilities and decision-making; and the key role of Regional Centres that will translate the teaching resources into local languages, adapt them according to local cultural needs, interface with regional educators and develop and serve as hubs of microbiology literacy education networks. The topics featuring in teaching resources are learner-centric and have been selected for their inherent relevance, interest and ability to excite and engage. Importantly, the resources coherently integrate and emphasise the overarching issues of sustainability, stewardship and critical thinking and the pervasive interdependencies of processes. More broadly, the concept emphasises how the multifarious applications of microbial activities can be leveraged to promote human/animal, plant, environmental and planetary health, improve social equity, alleviate humanitarian deficits and causes of conflicts among peoples and increase understanding between peoples (Microbial Biotechnology, 2023, 16(6), 1091-1111). Importantly, although the primary target of the freely available (CC BY-NC 4.0) IMiLI teaching resources is schoolchildren and their educators, they and the teaching philosophy are intended for all ages, abilities and cultural spectra of learners worldwide: in university education, lifelong learning, curiosity-driven, web-based knowledge acquisition and public outreach. The IMiLI teaching resources aim to promote development of a global microbiology education ecosystem that democratises microbiology knowledge.

    The combination of lifelong learning algorithms with autonomous intelligent systems (AIS) is gaining popularity due to its ability to enhance AIS performance, but the existing summaries in related fields are insufficient. Therefore, it is necessary to systematically analyze the research on lifelong learning algorithms with autonomous intelligent systems, aiming to gain a better understanding of the current progress in this field. This paper presents a thorough review and analysis of the relevant work on the integration of lifelong learning algorithms and autonomous intelligent systems. Specifically, we investigate the diverse applications of lifelong learning algorithms in AIS\'s domains such as autonomous driving, anomaly detection, robots, and emergency management, while assessing their impact on enhancing AIS performance and reliability. The challenging problems encountered in lifelong learning for AIS are summarized based on a profound understanding in literature review. The advanced and innovative development of lifelong learning algorithms for autonomous intelligent systems are discussed for offering valuable insights and guidance to researchers in this rapidly evolving field.

    基础医学教育阶段不足以支持医生全面诊断和评估多囊卵巢综合征(PCOS)。该研究旨在发现具有不同年度PCOS咨询次数的参与者在治疗选择上的差异,促进终身学习,推动医疗保健领域的均衡发展。
    这是一项多中心横断面调查。参与者的基本信息,在线收集PCOS知识和治疗方案.根据PCOS患者的年度咨询人数,医生分为三组:0-50人/年,50-200人/年,>200人/年,结果由χ2检验得出,Fisher精确检验,和多变量逻辑回归分析。
    该研究分析了1689份问卷,1206名医生(71.4%)每年接收不到50名妇女,388名医生(30.0%),每年有50-200名妇女,95名医生(5.6%),患者流失率超过200人。生殖内分泌学家通常有更高的机会进入诊所。随着访问次数的增加,越来越多的医生会认为患者更有可能有异常的血糖和体重。有大量咨询的医生更有可能使用亚洲或中国标准来评估肥胖。多变量分析涉及年龄、医院级别,专业,和每年的病人营业额,和更多的年轻医生积极评估血脂(优势比(OR)1.56,95%置信区间(CI)(1.16,2.16)),基层医院(OR0.65CI(0.44,0.89))选择OGTT进行血糖评估的比例低于三级医院。二级医院的医生在评估雄激素方面更积极。
    我们的调查发现内分泌评估存在差异,代谢筛查,根据接受不同患者咨询人数的妇产科医生人数,PCOS女性的治疗情况。强调了医师继续教育的重要性,促进终身学习。
    UNASSIGNED: The basic medical education stage is not enough to support physicians to fully diagnose and evaluate polycystic ovary syndrome (PCOS). The study aims to discover the difference in treatment choice between participants with different annual consultation number of PCOS, to promote lifelong learning, and drive balanced development within healthcare.
    UNASSIGNED: This is a multicenter cross-sectional survey. Participants\' basic information, knowledge of PCOS and treatment options were collected online. According to the annual consultation number of patients with PCOS, physicians were divided into three groups: 0-50 people/yr, 50-200 people/yr, and >200 people/yr, and the results were derived from χ2 test, Fisher exact test, and multivariate logistic regression analysis.
    UNASSIGNED: The study analyzed 1689 questionnaires, and 1206 physicians (71.4%) received less than 50 women per year, 388 physicians (30.0%) with an annual number of 50-200 women, and 95 physicians (5.6%) with patient turnover for more than 200 people. Reproductive endocrinologists generally have higher access to the clinic. As the number of visits increases, more and more physicians would perceive patients as more likely to have abnormal blood glucose and heavy weight. Physicians with large numbers of consultations are more likely to use Asian or Chinese standards to assess obesity. The multivariate analysis involved variables such as age, hospital level, specialty, and patient turnover annually, and more young doctors actively assessed lipid profile (odds ratio (OR) 1.56, 95% confidence interval (CI) (1.16, 2.16)), and primary hospitals (OR 0.65 CI (0.44, 0.89)) chose OGTT for blood glucose assessment less than tertiary hospitals. Physicians in secondary hospitals are more aggressive in evaluating androgens.
    UNASSIGNED: Our survey found differences in endocrine assessment, metabolic screening, and treatment in PCOS women in terms of the number of obstetrician-gynecologists who received different patient consultation numbers. The importance of continuing education for physicians is emphasized, to promote lifelong learning.

    近年来,生物信息学领域的研究集中在预测蛋白质的原始序列,一些学者认为DNA结合蛋白预测是一种分类任务。许多基于统计和机器学习的方法已被广泛用于DNA结合蛋白的研究。上述方法确实比基于人工分类的方法更有效,但在预测精度和速度方面仍有改进的空间。在这项研究中,研究人员使用平均块,离散余弦变换,离散小波变换,全局编码,归一化Moreau-Broto自相关和伪位置特异性评分矩阵提取进化特征。然后提出了基于终身学习架构的动态深度网络,以融合六个特征,从而允许更有效地对DNA结合蛋白进行分类。多特征融合允许比单个特征更准确地描述期望的蛋白质信息。该模型为生物信息学中的二分分类问题提供了新的视角,并拓宽了终身学习的应用领域。研究人员在三个数据集上进行了试验,并将它们与其他分类技术进行了对比,以显示该模型在本研究中的有效性。研究结果表明,本研究中使用的模型在单样本特异性方面优于其他方法(81.0%,83.0%)和单样本灵敏度(82.4%,90.7%),并在基准数据集上实现了高精度(88.4%,80.0%,和76.6%)。
    In recent years, research in the field of bioinformatics has focused on predicting the raw sequences of proteins, and some scholars consider DNA-binding protein prediction as a classification task. Many statistical and machine learning-based methods have been widely used in DNA-binding proteins research. The aforementioned methods are indeed more efficient than those based on manual classification, but there is still room for improvement in terms of prediction accuracy and speed. In this study, researchers used Average Blocks, Discrete Cosine Transform, Discrete Wavelet Transform, Global encoding, Normalized Moreau-Broto Autocorrelation and Pseudo position-specific scoring matrix to extract evolutionary features. A dynamic deep network based on lifelong learning architecture was then proposed in order to fuse six features and thus allow for more efficient classification of DNA-binding proteins. The multi-feature fusion allows for a more accurate description of the desired protein information than single features. This model offers a fresh perspective on the dichotomous classification problem in bioinformatics and broadens the application field of lifelong learning. The researchers ran trials on three datasets and contrasted them with other classification techniques to show the model\'s effectiveness in this study. The findings demonstrated that the model used in this research was superior to other approaches in terms of single-sample specificity (81.0%, 83.0%) and single-sample sensitivity (82.4%, 90.7%), and achieves high accuracy on the benchmark dataset (88.4%, 80.0%, and 76.6%).

    类增量学习(CIL)旨在识别在不同阶段出现的类。联合训练(JT)与所有班级一起训练模型,通常被认为是CIL的上限。在本文中,我们深入分析了CIL和JT在特征空间和权重空间上的差异。在比较分析的推动下,我们提出了两种类型的校准:特征校准和重量校准来模仿oracle(ItO),即,JT具体来说,一方面,特征校准引入偏差补偿,以保持特征空间中旧类的类决策边界。另一方面,权重校准利用遗忘感知权重扰动来增加可转移性并减少参数空间中的遗忘。有了这两种校准策略,该模型被迫在每个增量学习阶段模仿联合训练的特性,从而产生更好的CIL性能。我们的ItO是一种即插即用方法,可以很容易地实现到现有的方法中。在几个基准数据集上进行的大量实验表明,ItO可以显着并且始终如一地提高现有最先进方法的性能。我们的代码可在https://github.com/Impression2805/ItO4CIL上公开获得。
    Class-incremental learning (CIL) aims to recognize classes that emerged in different phases. The joint-training (JT), which trains the model jointly with all classes, is often considered as the upper bound of CIL. In this paper, we thoroughly analyze the difference between CIL and JT in feature space and weight space. Motivated by the comparative analysis, we propose two types of calibration: feature calibration and weight calibration to imitate the oracle (ItO), i.e., JT. Specifically, on the one hand, feature calibration introduces deviation compensation to maintain the class decision boundary of old classes in feature space. On the other hand, weight calibration leverages forgetting-aware weight perturbation to increase transferability and reduce forgetting in parameter space. With those two calibration strategies, the model is forced to imitate the properties of joint-training at each incremental learning stage, thus yielding better CIL performance. Our ItO is a plug-and-play method and can be implemented into existing methods easily. Extensive experiments on several benchmark datasets demonstrate that ItO can significantly and consistently improve the performance of existing state-of-the-art methods. Our code is publicly available at https://github.com/Impression2805/ItO4CIL.

    本文探讨了一种新的终身学习方法,具有共享和私有潜在表示(SPLR),这是通过突触智力学习的。要解决一系列任务,通过考虑整个参数学习轨迹,SPLR可以学习变化很小的任务不变表示,和特定于任务的功能,这些功能会在整个参数更新轨迹上发生很大变化。因此,在终身学习场景中,我们的模型可以获得所有任务共享的任务不变结构,并且还包含一些特定于每个任务的私有属性。为了减少参数数量,在权重中采用了用于促进稀疏性的1正则化。我们在终身学习场景下使用多个数据集来验证我们的SPLR,在这些数据集上,与现有的终身学习方法相比,它可以获得可比的性能,学习稀疏网络,这意味着更少的参数,同时需要更少的模型训练时间。
    This paper explores a novel lifelong learning method with Shared and Private Latent Representations (SPLR), which are learned through synaptic intelligence. To solve a sequence of tasks, by considering the entire parameter learning trajectory, SPLR can learn task-invariant representation which changes little, and task-specific features that change greatly along the entire parameter updating trajectory. Therefore, in the lifelong learning scenarios, our model can obtain a task-invariant structure shared by all tasks and also contain some private properties that are task-specific to each task. To reduce the parameter quantity, a ℓ1 regularization to promote sparsity is employed in the weights. We use multiple datasets under lifelong learning scenes to verify our SPLR, on these datasets it can get comparable performance compared with existing lifelong learning approaches, and learn a sparse network which means fewer parameters while requiring less model training time.

    本研究以终身学习为中介,探讨信息素养对医学生创新能力的影响。在医学生中进行了横断面调查,以收集数据,通过分层方便的抽样程序招募,开伯尔·普赫图赫瓦,巴基斯坦。问卷是通过书面许可访问每一所大学来亲自管理的。使用偏最小二乘结构方程模型收集并分析了总共473个调查响应。结果表明,医学生的信息素养对其创新能力有直接和间接但积极的影响。终身学习不仅对创造技能产生直接但积极的影响,而且还介导了信息素养与创造技能之间的关系。信息素养如何通过终身学习的中介作用影响创造力的经验证据可能会为信息素养指导的政策和实践提供信息。这些结果可能有助于院士和信息专家在不仅在巴基斯坦而且在其他发展中国家的医学生的课程中启动有关信息素养的公认或综合课程。这项研究将对现有的信息素养研究做出有价值的贡献,因为到目前为止,从未研究过信息素养和创造力之间的终身学习的中介作用。
    This research investigated the influence of information literacy on the creative skills of medical students through the mediation of lifelong learning. A cross-sectional survey was conducted for data collection among medical students, recruited through a stratified convenient sampling procedure, of Khyber Pakhtunkhwa, Pakistan. The questionnaire was personally administered by visiting each college with written permission. A total of 473 survey responses were collected and analysed using the partial least squares structural equation modelling. The results revealed that the information literacy of medical students had a direct and indirect but positive influence on their creative skills. Lifelong learning not had a direct but positive effect on creative skills but also mediated the relationship between information literacy and creative skills. The empirical evidence for how information literacy influences creative skills through the mediated role of lifelong learning may inform policy and practice for information literacy instructions. These results may help academicians and information specialists to initiate a credited or integrated course on information literacy in the curriculum of medical students not only in Pakistan but also in other developing countries. This research would be a worthwhile contribution to the existing research on information literacy as the mediated role of lifelong learning between information literacy and creative skills has never been examined so far.

    这项研究考察了信息素养(IL)对工作绩效的影响,并在巴基斯坦新闻工作者中发挥了终身学习和创造力的中介作用。在四个省的新闻俱乐部中使用在线问卷进行了横断面调查(例如,旁遮普,信德省,开伯尔·普赫图赫瓦,和Bal路支斯坦)和联邦首都伊斯兰堡进行数据收集。使用偏最小二乘结构方程模型分析了收到的1084个响应。结果表明,新闻工作者的IL对其工作绩效有直接和间接但积极的影响。终身学习和创造力技能也介导了IL与工作绩效之间的关系。这项研究为IL如何直接影响工作绩效以及间接影响终身学习和创造力的中介作用提供了经验证据。这些务实的见解可以使院士和企业了解IL在工作场所对提高组织绩效和实现竞争优势的重要性。这样的结果还可以启动针对现有以及未来记者的教学计划,以传授IL教育。这项研究可能是对一般工作场所背景下的现有IL研究的有价值的贡献,特别是对记者的工作场所,因为到目前为止还没有这样的研究出现。
    This study examined the effect of information literacy (IL) on work performance with mediating role of lifelong learning and creativity among journalists in Pakistan. A cross-sectional survey using an online questionnaire was conducted in the press clubs of four provinces (e.g., Punjab, Sindh, Khyber Pakhtunkhwa, and Baluchistan) and the federal capital Islamabad for data collection. The received 1084 responses were analyzed using the partial least squares structural equation modelling. The results indicated that IL of journalists had a direct and indirect but positive influence on their work performance. The lifelong learning and creativity skills also mediated the relationship between IL and work performance. This study provided empirical evidence for how IL directly influence work performance and indirectly with the mediated role of lifelong learning and creativity. These pragmatic insights may inform academicians and enterprises about the IL importance at workplace for enhancement of organizational performance and achieving a competitive advantage. Such results may also initiate an instruction program for existing as well as for prospective journalists to impart IL education. This study could be a worthy contribution to the existing IL research in the workplace context in general and of journalists\' workplace in particular as no such study has appeared so far.

    智能故障诊断(IFD)在保护机械免受灾难性事故的影响中起着不可或缺的作用。现有的IFD方法主要是在一次性学习的框架下开发的。因此,它们在完整数据集的假设下工作。然而,立即获得机械故障的完整数据集是不现实的。更实际,随着时间的推移,将逐步获取新的数据。因此,迫切需要开发IFD模型的增量学习(IL)功能,以便从新数据中不断学习新知识。为此,这项研究提出了一种改进的广泛学习系统(IBLS),用于终身学习IFD。首先,初始IBLS是基于原始的广义学习系统(BLS)构建的。然后,IBLS的IL功能针对三种情况开发:增加故障样本,增加故障模式,增加运行条件。基于这些IL能力,IBLS可以逐步更新,以了解越来越多的诊断功能。最后,利用三个高速列车轴承实验验证了IBLS的有效性,圆盘组件,和凯斯西储大学轴承。结果表明,IBLS能够从新数据中不断学习新知识。此外,IBLS的诊断准确率为12.45%,7.84%,在三个案例研究中,比原始BLS高出5.10%。令人满意的结果证明,提出的IBLS是解决终身学习IFD问题的有用方法。
    Intelligent fault diagnosis (IFD) plays an indispensable role in protecting machinery from catastrophic accidents. Existing IFD methods are mainly developed in the framework of one-time learning. Therefore, they work under the hypothesis of complete dataset. Nevertheless, it is unrealistic to gain the complete dataset of machinery faults at once. More practically, new data will be progressively acquired over time. Therefore, it is urgently required to develop the incremental learning (IL) capabilities for IFD models to learn new knowledge continually from new data. For this purpose, this study proposes an improved broad learning system (IBLS) for lifelong learning IFD. Firstly, the initial IBLS is constructed based on the original broad learning system (BLS). Then, the IL capabilities of the IBLS are developed for three scenarios: increasing fault samples, increasing fault modes, and increasing running conditions. Based on these IL capabilities, the IBLS can be progressively updated to learn more and more diagnosis functions. Finally, the effectiveness of the proposed IBLS is verified using three experiments of high-speed train bearing, disc component, and Case Western Reserve University bearing. The results show that the IBLS is capable of learning continually new knowledge from new data. Besides, the diagnosis accuracy of the IBLS is 12.45%, 7.84%, and 5.10% higher than that of the original BLS in the three case studies. The satisfying results prove that the proposed IBLS is a useful method to solve the lifelong learning IFD problem.

    The use of technology to facilitate better living and learning is gaining popularity worldwide. More and more older adults are technology users and participating in online learning. While there is ample research examining the factors affecting older adults\' behavioural intention to use technology more generally, less is known about their views of using technology in online learning environments. Applying the model for the adoption of technology by older adults (MATOA) developed by Kenneth Hsiche Wang et al., the authors of the study presented here investigated the attitudes of older adults towards technology adoption for online learning. They interviewed 20 adults aged 52-73 who had enrolled in a diploma course in a higher educational institution in Hong Kong. The results show that participants held favourable attitudes towards online learning after several practice sessions. While they had confidence in their future use of technology, they stated that the availability of technical and social support affected their intention of continuous learning using technology in online settings.
    Utilisation de la technologie par les seniors à Hongkong pour apprendre en ligne – Utiliser la technologie pour faciliter l’amélioration de la qualité de vie et l’apprentissage, une activité qui jouit d’un engouement croissant dans le monde entier. De plus en plus de seniors se servent de la technologie pour se livrer à des activités d’apprentissage en ligne. Tandis que de nombreuses recherches portent sur les facteurs qui influent sur l’intention comportementale des seniors à utiliser la technologie d’une manière plus générale, nous savons peu de choses sur leurs points de vue à ce sujet dans les environnements d’apprentissage en ligne. S’appuyant sur le modèle pour l’adoption de la technologie par les seniors (model for the adoption of technology by older adults/MATOA) élaboré par Kenneth Hsiche Wang et coll., les auteurs de la présente étude se sont penchés sur les attitudes des seniors concernant l’adoption de la technologie pour apprendre en ligne. Ils ont interviewé 20 adultes âgés de 52 à 73 ans qui s’étaient inscrits à un cours diplômant dans un établissement d’enseignement supérieur à Hongkong. Les résultats indiquent que les participants se montraient favorables à l’apprentissage en ligne une fois qu’ils avaient participé à plusieurs séances d’entraînement. Tout en se sentant confiants quant à l’utilisation qu’ils feraient à l’avenir de la technologie, ils ont déclaré que la disponibilité d’un soutien technique et social influait sur leur intention d’apprendre en permanence en utilisant la technologie dans un environnement en ligne.
