ABSTRACT

Historic Japanese textiles from over 1000 years ago generally show marked deterioration and only very rare examples show their original forms and much information about textile reproduction has been lost. The replication of textile braids lacks systematic methodology and is still being practiced by only few individual braiding experts. The recreation of original braids as close as possible to original braids is a part of Japan’s intangible cultural heritage. The aim of this study is to clarify the decision-making procedure through which the braiding experts can decipher the original braiding structures. As a preliminary study of this project, interviews of a braid researcher and a replicating expert, Makiko Tada were performed regarding her working practices. It is important to clarify the braiding parameters for structural analysis such as the number of transits and the balance of ridges, and it became clear that the orientation of multiple colored threads plays an important role. The expert’s replicate works were also analyzed using a text-mining statistical technique to clarify the relationship of braiding parameters. The relationship between each braiding parameter and production method such as loop manipulation and Taka-dai became clear. As a result, the process of deciphering the original braid structure has been compiled in simplified workflows, which could contribute to the standardization and improvement in efficiency of replication of cultural property braids.  相似文献

液滴撞击固体壁面现象常见于动力机械、喷雾冷却和薄膜材料沉积制备等工业生产中。将石墨烯和碳纳米管作为分散颗粒，应用超声波分散技术制备均匀性与稳定性良好的树脂基纳米流体。利用高速摄像技术，研究纳米流体液滴撞击固体壁面的动力学行为。基于有限元法，通过修正的幂律黏度模型耦合纳米流体的剪切变稀特性，采用水平集方法捕捉相界面的移动，建立纳米流体液滴撞击固体壁面的数值模型。模拟结果与实验结果较好一致，验证了数值模型的正确性与准确性。研究发现实验配制的纳米流体表现出非牛顿剪切变稀特性，纳米颗粒的加入抑制了液滴撞击固体壁面过程中的铺展和回缩行为。随着幂律指数m的减小，液滴撞击固体壁面后的铺展范围变大。随着表面张力的增大，液滴的无量纲直径在铺展阶段无明显变化，但在回缩阶段逐渐减小。  相似文献

The role of a digital engineering platform in appropriating the creation of new work-related mind-set and organisational discourse in a large multi-national company     

《International Journal of Information Management》2019

This paper reports on a case study involving a strategic and innovative approach to creation of an in-house multifaceted digital engineering platform (the DEP) in overcoming a number of organisational problems at a multinational engineering company. The DEP was to be used strategically for simplifying the operational complexity and to create and appropriate new work-related mind-set and new organisational discourse to achieve homogenous working across the organisation, which is a huge challenge. The need for this system emerged from the need to resolve many organisational services related problems that carried phenomenal amount of processes, health and safety risks and to regulate, and, control the running of engineering project. Research data were collected using a longitudinal case study approach over a period of six months. In order to make sense of how the DEP helped the organisation, the study used certain elements of Extended Structuration Theory as a lens to assess the case study. This research discovered that the DEP succeeded in creating and appropriating work-related mind-set and organisational discourse. It also had real influence on working processes and employees at all levels while encouraging transparency, responsiveness, agility and accountability. It continues to help the organisation to govern, manage and maintain good standard of service but many barriers still remain.  相似文献   

Child safeguarding practices in light of the Deserving/Undeserving paradigm: A historical & contemporary analysis     

《Child abuse & neglect》2019

BackgroundContemporary child protection systems in the UK need to be seen in light of the late nineteenth century child rescue movement, at a time of curbs in public spending, shifts in attitudes towards children’s welfare and the development of social work. There are similarities in the social, institutional and legal contexts, between the nineteenth century and today, centralising ‘deservedness’, that determined and determines children’s access to services.ObjectiveThe current article compares historical data and practices of children in care in the UK, encompassing 1881–1918, with contemporary data and practices, through the lens of the deserving/undeserving paradigm, inherited from the Poor Law of 1834.Participants and SettingDrawing on two data sets, namely historic children’s case files (N = 108), 1881–1918 from the Children’s Society (a philanthropic institution) highlighting the perception of custodians, doctors, professionals, as well as children and parents, and current data from interviews with young care leavers and safeguarding practitioners (N = 42), our research focuses on the most disadvantaged children with complex needs and damaging (pre)care experiences.MethodsData is analysed using thematic content analysis, framed within critical realist ontology, taking account of stratified non-linear dynamics of processes at different levels.Results and ConclusionIn both data sets the inability to support certain children is justified by referring to their complex needs and mental health and behavioural problems., Here, the child is held accountable and placed in the ‘undeserving’ category and consequently misses out on help and support, highlighting a need for awareness, and reflective and reflexive practice among practitioners/professionals.  相似文献   

A meta-analytic review of interventions to improve children’s attitudes toward their peers with intellectual disabilities     

《Contemporary educational psychology》2021

Children’s biases toward their peers with intellectual disabilities tend to have negative developmental and social consequences for those with intellectual disabilities. As a result, researchers developed intervention programs to reduce biases toward children with intellectual disabilities. This meta-analysis is a quantitative summary of 59 studies and 144 hypothesis tests involving intervention programs to change children’s attitudes toward their peers with intellectual disabilities. Results revealed an overall significant effect (d = 0.44): following intervention programs, children’s attitudes toward their peers with intellectual disabilities increased. Moderators indicate that the most effective interventions were those that occurred over multiple sessions, involved active engagement in multiple strategies and social interactions, emphasized equal status contact that was unstructured or indirect, and had little adult guidance. Interventions had no effect on changing children’s perceptions of competence and participants in junior high had more negative attitudes following the interventions. Findings provide guidance for researchers, educators, and counselors who seek methodologies to reduce biases toward children with intellectual disabilities.  相似文献   

Locked-down digital work     

《International Journal of Information Management》2020

Covid-19 and the related lockdown in many countries made digital work no longer just an option, but the new norm for many office workers who began to make sense of a new range of benefits of digital work tools. Based on my own observations and on observations shared by executives in New Zealand and Europe, I illustrate in this article how the lockdown acted as a facilitator for digital work. Further, I show how the lockdown gave many individuals a flawed impression of digital work, i.e. their experience occurred during exceptional circumstances and led them to draw false conclusions about digital work. I examine some misconceptions of locked-down digital work and discuss the implications of locked-down digital work for research and practice.  相似文献   

Decoding digital transformational outsourcing: The role of service providers’ capabilities     

《International Journal of Information Management》2021

The business process outsourcing industry has got disrupted, first by the significant shift in value creation activities from the clients to the service providers, and second by pervasive digital penetration, resulting in the emergence of Digital Transformational Outsourcing (DTO). Service providers now play a more significant role, making their capabilities important. In the new context, service providers require a uniquely different set of dynamic capabilities to handle end-to-end business functions on behalf of their clients while delivering digital value propositions.We study 26 of the largest global business process outsourcing providers to conceptualise and identify six dynamic capabilities of service providers salient in the new context, i.e., consultative, orchestration, insights, network management, knowledge access, and standardisation. Interviews conducted with industry experts provided evidence in support of the identified dynamic capabilities. A novel firm capability dataset was created using secondary data, and using fuzzy-set Qualitative Comparative Analysis (fsQCA), we identify configurations for high and low performance and find them to vary by the firm's broad/narrow scope.  相似文献
