Managing Uncertainty for Preventive Conservation

ABSTRACT

This paper examines how conservators engage with uncertainty when creating preventive conservation strategies. It argues that by recognising contexts in which uncertainty will be encountered conservators can develop effective management strategies. A typology of uncertainty explores a range of categories of uncertainty, their experience in preventive conservation and identifies distinct approaches to manage them. Managing uncertainty may include acts of defining its parameters, exposing and resolving through communication or protecting from with contingency. Whatever approach is adopted it must be accepted that uncertainty cannot be avoided. It is important therefore to aim to live well with uncertainty and the paper advocates for preventive conservation applications of strategies recommended in health care for patients with life-threatening illnesses. These strategies include working on things that can be controlled, goal setting, acceptance and factoring in emotions. The ability to identify contexts in which uncertainty is inbuilt should trigger those concerned with preventive conservation to activate strategies developed for managing and living well with uncertainty.     

减少不确定性与含糊交际理论在交际中的运用

语言交际是一种复杂的人类言语行为,交际者根据交际目的、环境,对象以及各种随机因素的交互作用而作出言语决策.语言交际策略的使用不但要遵循顺应理论的原则,而且还受元语言意识的影响.减少不确定性和含糊交际,作为大家经常使用的交际策略,它们的最终目的都是实现信息的交换,满足交际者的需求,顺利完成交际任务.     

Regarding uncertainty in teachers and teaching

The literature on teacher uncertainty suggests that it is a significant and perhaps inherent feature of teaching. Yet there is disagreement about the effects of these uncertainties on teachers as well as about the ways that teachers should regard them. Recognition of uncertainties can be viewed alternatively as a liability or an asset to effective teaching. Findings from the literature on uncertainties in teaching are summarized and analyzed, including explanations in the research about what accounts for and contributes to uncertainties. Recommendations for research and professional development are provided.     

康托实数集合不可数证明中的四种错误探析

从逻辑、无穷观、极限论和证明的思路及具体的操作过程,分析了新发现的康托在实数集合不可数证明中所存在的四种错误,得到＂由于与现有经典无穷理论体系、经典极限论和经典数量体系密切相关的数学基础理论中所存在的缺陷,康托在这类证明中无法回避这四种很严重但却很隐蔽的错误＂的明确结论.特别是其中的逻辑错误使这样的证明无意中成了一种典型的数学魔术.     

制造业生产调度体系探讨

论文以制造业生产调度体系为研究对象,从生产车间调度的目标、方法、手段、资源等基本要素入手,总结了传统生产调度系统在实际生产中的问题,并概括了系统集成视角下的生产调度方法及其改进措施,介绍了不确定条件下生产调度策略及评价指标。运用系统集成的思想,探讨了供需链环境下的制造业生产调度系统模式,最终提出了生产调度系统的集成化、动态化、高效智能化、柔性化和排程可视化等发展方向。

团队网络结构、交互记忆系统与团队绩效关系的实证研究

基于社会网络视角,采用问卷调查法,以124个制造业生产团队为研究对象,对团队网络结构、交互记忆系统与团队绩效的关系进行探讨。实证研究结果表明,团队工具性网络强度与情感性网络强度对交互记忆系统有显著的正向影响;团队网络的非中心度对交互记忆系统有积极影响;交互记忆系统与团队绩效有显著的正向关系,并受到任务不确定性的调节作用。     

基于“3R原则”的水泥工业企业节能减排路径探析——以贵州省水泥工业企业为例

水泥工业作为建材行业的传统生产工业,是典型的高能耗、高材耗、高污染的行业,贵州省由于经济发展的限制这一特性表现得尤为突出。加快推进水泥工业企业的节能减排刻不容缓。运用循环经济理论,以＂3R原则＂为指导,通过清洁生产,实现水泥工业的＂减量化＂;技术创新,促进水泥工业的＂再利用＂;建立生态产业链,实现水泥的＂资源化＂以及政...
