AbstractManufacturing applications address business to business (B2B) with highly customised applications developed for specific requirements, offering highly specialised solution-oriented and service-based software components, systems, and digital tools that aim at a fast and accurate decision-making support system. The purpose of this paper is to describe the implementation of digital technologies for operations management using manufacturing or engineering apps (eApps), for product design and manufacturing processes. In particular, starting from the specific needs of two companies from mature European industries as automotive and food, this work depicts how this kind of solutions can support companies and improve their operations. In particular, related benefits and challenges faced for the full implementation of the developed tools are highlighted. Moreover a business model to exploit the manufacturing apps is also proposed. The business model proposed for the exploitation of the eApps supports the commercialisation of all the revenue streams offered by this rapidly growing sector taking into account the specific needs of the concerned stakeholders through a diversified value proposition. 相似文献

本文假定透明交易者对额外投资机会回报率的标准差(方差,投资风险)存在暧昧,这种认知暧昧性抑制了透明交易者的投资行为,会导致风险资产溢价过高及社会福利损失.透明交易者是暧昧厌恶的投资者,其投资决策依据光滑暧昧厌恶模型,需求函数呈现连续且光滑的特征.而不透明交易者,通过支付一定的信息获取成本获得私有信息而具有信息优势,他们是标准的风险厌恶的投资者.通过构建理性预期均衡,本文的研究发现:初始资产严格为正的透明交易者将获得严格为正的超额收益;提高信息获取成本将减少不透明交易者的比例,从而增加风险资产溢价,降低福利水平,因而不是一项好的管制措施;而旨在提高市场透明度降低交易者暧昧性的举措总有利于提高福利水平. 相似文献

This study seeks to explain the influence of quality management on the relationship between open innovation and performance. We propose that, to contribute to open innovation performance, an organisation’s commitment to quality improvement must rely on the combination of its own resources and capabilities and its open innovation partners’ resources and capabilities. Specifically, we examine the moderating role of an interorganisational IT infrastructure and the complementarity of learning styles among an organisation committed to quality improvement and its supply network. Using data from 270 managers of European firms, our results show that the negative effects of quality management on open innovation performance can be overcome by complementing the organisation’s learning style with that of its open innovation partner, particularly, its supply network, and, most importantly, obtaining information technologies compatible with those of its supply network members. 相似文献

What is the attitude of Latin American undergraduate social work students toward poverty? An earlier study from Europe and other countries worldwide found that most graduating social work students who participated in the research were clear about the socio-structural causes of social problems such as poverty. Still, no data on this topic is available for Latin American countries. The aims of this study were: (1) to describe and to compare eight Latin American graduating undergraduate social work student groups regarding their attitudes toward poverty, as measured by two scales: Causes of poverty scale and Ways of dealing with poverty; and (2) to discuss some of the implications of the study for social work education and practice. Using a quantitative transnational-comparative design, a total sample of 525 nonrandomly selected, graduating undergraduate social work students from eight Latin American countries responded to a self-administered questionnaire. An individualistic attitude to understanding and to dealing with poverty emerged in the majority of the student groups. Multivariate procedures and inferential analyses demonstrated variations across the student groups. Implications for social work education and practice are discussed. 相似文献

This article focuses on English language teaching in Brazilian public schools, based on experiences in primary and secondary education, as well as in Teaching Practicum courses at a university. Through these experiences, the article critiques the overemphasis on grammar and the lack of an intercultural approach. The author engages the reader with a theoretical discussion regarding the connection between language and culture and the possibilities for the implementation of intercultural principles. The article closes with some reflections on what intercultural language learning looks like in practice. 相似文献

Susan Boyle’s audition for the television talent competition Britain’s Got Talent attracted global attention and widespread media discourse. In this article, I would like to examine this discourse to consider how Boyle’s success troubles conventional constructions of both learning disability and celebrity.
I extend Ciara Evans’s recognition that learning disability is invisible to reflect on the media responses to Boyle’s impairment. This reflection notes that even within Boyle’s own discourse, she is loosely positioned as having ‘some sort of learning disability’.
Detailed attention is given to the aetiological account of the ‘brain damage’ Boyle ‘suffered’ at birth. The analysis will consider the correlation with scientific discourse, trauma theory and the imposed biography to suggest that the construction of Boyle as both contained and unpredictable is already implicit in the aetiological narrative. 相似文献

社会领域也存在某种惯性趋势,即社会趋稳性。这一概念的提出旨在说明,一切不稳定的产生,必定是受到某种作用力的结果。而社会趋稳性与变动力量的结合,便会造成不同程度的反作用力。这种反弹行为在实践中很容易被界定为"不稳定因素"。由于维稳的主客体都是人,而"人是需求动物",所以,维稳的具体政策若不能够融入人的思考、理解及感情,将很难实现人际有效的沟通,进而妨碍动态稳定的实现。以组织平衡理论、需求层次理论、安全阀理论及组织学习理论为基础的双回路维稳模型的提出,旨在强调人类需求、基本秩序以及自然法则在维稳中的关键作用。 相似文献
