A primary goal of The Pennsylvania State University's new Engineering Entrepreneurship (E‐SHIP) Minor is to build students' life skills so they can succeed within innovative, product‐focused, cross‐disciplinary teams. The E‐SHIP Minor is designed for undergraduate students majoring in engineering, business, or IST (Information Sciences and Technology) who aspire to be innovation leaders for new technology‐based products and companies. This paper outlines five E‐SHIP program components to meet this mission: the core courses for the minor, E‐SHIP competitions in which students exhibit their products and ideas, the E‐SHIP Event Series, student organizations to support out‐of‐classroom entrepreneurial interest, and team projects for local industry and Penn State researchers. Penn State's engineering entrepreneurship program is reviewed, summarizing both quantitative and qualitative assessment data to date, previewing future assessment plans, and providing a summary of lessons learned during the development and implementation of this program. 相似文献

本文选取了国外典型社会团体IEEE和ASTM,以及全国团体标准信息平台上活跃程度前十名的国内社会团体,对标准化组织机构的情况进行了对比,提炼了国外社会团体标准化组织机构的特点:设有专门的标准管理机构和标准制定机构;机构下又根据业务特点设有各类分支机构;不同的机构合力为标准制定发挥作用;机构通过制度化手段对标准化工作进行管理。总结了我国社会团体标准化组织机构的不足:由于标准化发展历程较短,缺乏标准化工作经验和基础,对标准化组织机构的建设还不够重视,导致了我国社会团体的标准化组织机构设置的层次单一、机构规模较小、工作机制不够明晰、标准管理机构对标准制定工作的管理力度不强、组织机构设置不够透明等问题。从机构设置的原则、内容和要求等方面提出了我国社会团体机构建设的建议。 相似文献

Philosophy of engineering lays the philosophical foundation of recognition, understanding and management of engineering. Being the kernel of philosophy of engineering, engineering ontology becomes the master key to understanding of engineering. The paper proposes and interprets the principal theses of engineering ontology, which differs from understanding of engineering in separate elements. Engineering ontology believes that engineering is the direct, realistic productivity that runs dynamically and feasibly and creates values. Engineering involves the relationship between human beings and the nature as well as the relationship between human beings and the society, and it has been a basic motive force and a basic way of promoting the social development, so that engineering gains the ontological status and fundamental value in social existence and social development. From the historical point of view, the engineering appears before the emergence of technology and science. Engineering has its own basis for existence, its own structure and its own laws for movement and evolution. Engineering should not be simply regarded as the ramification and derivative from science or technology. Engineering ontology is the theoretical basis of the triism of “science, technology, and engineering”. To understand and handle the mutual relationship among engineering, technology and science, by the evaluation criteria of engineering as the direct productivity, the process and effect of engineering-centered selection, integration and construction must be emphasized and the characteristic and mechanism of selection, integration and construction must be paid high attention. Under no circumstance may the engineering be deemed as an unchanged matter, which is constantly evolving and developing, so the studies on engineering ontology are closely and internally related with the theory of engineering evolution. 相似文献

In the life-cycle of large projects, the operational phase lasts the longest, costs the most and substantially benefits the project. During the whole phase, energy, material and human resources may cost a lot. Effective control of such costs is one of the main targets of engineering management informatization. How to lower the organization collaboration cost in project management and how to support effective collaboration among different areas, organizations and departments in the ways of technology and management are major goals in engineering management informatization. In the phase of project operation, project owners, partners and customers are the stakeholders of engineering management informatization. Through the case of airport management informatization, inherited and innovation of engineering management informatization will be discussed. It is illustrated that airport informatization is the innovation of business model and technology applications through the analysis and study on cases of airport informatization. 相似文献

关于技术创新问题的若干认识 总被引:2,自引:0,他引:2
讨论了科学、技术、工程、产业的本质与含义,研究了科学-技术-工程-产业的知识链,指出技术、工程与经济的关联程度远高于科学与经济的关联程度。文章强调科学与基础研究是资金向知识的转化,而技术创新则是在资本的支持下,使知识通过市场向效益、利润的转化。工程师是新生产力的重要创造者,也是新兴产业的积极开拓者。工程师要面对的是不同层次、不同领域、不同尺度上的技术创新。在经济快速成长时期,应该更加重视工程师的创造性劳动。培养大批工程技术创新人才是推进经济发展、社会进步的必然要求。 相似文献
