Production of green surfactants: Market prospects     

《Electronic Journal of Biotechnology》2021

Science has greatly contributed to the advancement of technology and to the innovation of production processes and their applications. Cleaning products have become indispensable in today’s world, as personal and environmental hygiene is important to all societies worldwide. Such products are used in the home, in most work environments and in the industrial sectors. Most of the detergents on the market are synthesised from petrochemical products. However, the interest in reducing the use of products harmful to human health and the environment has led to the search for detergents formulated with natural, biodegradable surfactant components of biological (plant or microbiological) origin or chemically synthesised from natural raw materials usually referred to as green surfactants. This review addresses the different types, properties, and uses of surfactants, with a focus on green surfactants, and describes the current scenario as well as the projections for the future market economy related to the production of the different types of green surfactants marketed in the world.How to cite: Farias CBB, Almeida FCG, Silva IA, et al.

CloudChain: A novel distribution model for digital products based on supply chain principles     

《International Journal of Information Management》2018

Cloud computing is a popular outsourcing solution for organizations to support the information management during the life cycle of digital information goods. However, outsourcing management with a public provider results in a lack of control over digital products, which could produce incidents such as data unavailability during service outages, violations of confidentiality and/or legal issues. This paper presents a novel distribution model of digital products inspired by lean supply chain principles called CloudChain, which has been designed to support the information management during digital product lifecycle. This model enables connected networks of customers, partners and organizations to conduct the stages of digital product lifecycle as value chains. Virtual distribution channels are created over cloud resources for applications of organizations to deliver digital products to applications of partners through a seamless information flow. A configurable packing and logistic service was developed to ensure confidentiality and privacy in the product delivery by using encrypted packs. A chain management architecture enables organizations to keep tighter control over their value chains, distribution channels and digital products. CloudChain software instances were integrated to an information management system of a space agency. In an experimental evaluation CloudChain prototype was evaluated in a private cloud where the feasibility of applying supply chain principles to the delivery of digital products in terms of efficiency, flexibility and security was revealed.  相似文献

企业产品平台独立性差异及影响机理——一个对比案例研究          下载免费PDF全文

苏敬勤  林菁菁  张雁鸣 《科研管理》2019,40(10):220-229

摘要：产品平台对于复杂工业企业取得竞争优势的重要性已经成为学者们的共识，但现有研究对于产品平台独立性差异及导致差异的机理并未做深入探讨。本文采用双案例比较研究方法，选择两家在产品平台独立性上存在较大差异的企业--大连机车与一汽轿车--进行对比分析，探讨影响企业产品技术平台独立性的主要因素及机理关系。研究发现：（1）产品－市场结构、技术战略、资源协奏模式是影响产品平台独立性差异的主要因素；（2）在产品-市场结构、技术战略的影响下，平台独立性差异企业会表现出不同的资源协奏模式--多元协奏与单一拼接。（3）产品-市场结构、技术战略与资源协奏模式之间存在密切的互动关系：产品-市场结构影响下的技术战略，及技术战略影响下的资源协奏模式最终影响平台独立性。本研究明确了不同企业在产品平台独立性方面产生差异的原因并提出了相关机理，补充了关于产品平台独立性的相关研究。  相似文献   

Customer participation and new product performance: Towards the understanding of the mechanisms and key contingencies     

Todd Morgan  Michael Obal  Sergey Anokhin 《Research Policy》2018,47(2):498-510

In a study of 243 firms of varying sizes across 14 different industries, we investigate the effect of customer participation on new product development performance. We confirm that overall customer participation is positively related to new product development performance and that the effect is mediated by innovativeness. We also demonstrate that these effects are contingent upon absorptive capacity of the firm in question such that firms with high absorptive capacity stand to gain more from engaging their customers in new product development than firms with low absorptive capacity, especially at the later stages of the NPD process. The results are robust to alternative estimation techniques, measures employed to operationalize key concepts, and the industrial makeup of the sample. Post hoc analyses provide non-trivial managerial implications for the decision makers at the firm level.  相似文献

基于产品市场视角，本文采用多元回归分析方法，考察企业社会责任（CSR）负面事件对产品市场竞争力的影响，以及高管团队社会资本的缓解效应。研究发现：CSR负面事件会显著降低企业产品市场竞争力；道德型负面事件比能力型负面事件对企业产品市场竞争力的消极影响更强；CSR负面事件对竞争行业企业产品市场的消极影响比垄断行业企业更为明显；高管团队社会资本可以显著缓解CSR负面事件对企业产品市场竞争力的冲击。  相似文献   

异质设计动机下的股权激励对产品创新能力的影响          下载免费PDF全文

杨慧辉  徐佳琳  潘飞  马二强 《科研管理》2018,39(10):1-11

在厘清股权激励对企业产品创新行为影响机理的基础上，本文采用案例研究方法，分析控股股东与管理层权力博弈结果对股权激励动机的影响，以及不同的股权激励设计动机对企业的产品创新行为的异质影响。研究发现，管理层权力主导和控股股东权力主导所造成的内部人控制问题，会使得股权激励沦为内部人谋取私有收益的工具，缩减提升公司竞争能力和可持续发展能力但风险高、周期长的产品创新的投入，进而削弱产品创新的成果转化能力。只有在控股股东发挥积极监督治理的环境中实施的股权激励才具备提升创新投入和产出成果转化能力的作用。  相似文献

Peteris Daugulis  Anita Sondore 《PRIMUS》2018,28(1):90-95

Efficient visualizations of computational algorithms are important tools for students, educators, and researchers. In this article, we point out an innovative visualization technique for matrix multiplication. This method differs from the standard, formal approach by using block matrices to make computations more visual. We find this method a helpful alternative for introducing matrix multiplication.  相似文献   

粤港澳大湾区跨境体育消费实证研究* ——以广东居民赴香港参加体育赛事为例     

王淋燕  周良君  李洋洋  丘庆达 《广州体育学院学报》2020,(5):1-8

粤港澳大湾区以其独特的地理优势，在国家发展大局中具有重要的战略地位。采用问卷调查、深度访谈和中介效应分析等方法，选取广东居民赴香港参加体育赛事者为调查对象，了解两岸居民参与体育赛事受到哪些因素的影响及其影响程度，帮助相关部门企业制定合理策略促进两岸体育爱好者交流及地方经济增长，同时进一步拓展了跨境消费行为研究,特别是跨境体育消费研究。结果显示，赛事产品因素及相关吸引因素对个人态度及行为意愿具有重要影响，而经济因素和交通因素对于跨境体育消费者的决策影响十分有限。通关因素、货币汇率因素对跨境参加体育赛事影响不明显。  相似文献
