Réseau interpersonnel, coopération et capacité à innover / Interpersonnal network, cooperation and innovativeness

Audran, Marilyne 31 May 2012 (has links)
La thèse vise à étudier l’impact des réseaux interpersonnels sur la capacité à innover (innovativeness) des inventeurs. Les contributions académiques soulignent qu’il existe une forte relation entre les réseaux interpersonnels et la coopération interindividuelle. Le comportement coopératif apparaît comme le meilleur moyen de mener à bien un projet innovant, un projet complexe. Nous énonçons donc l’hypothèse selon laquelle les collaborations répétées au sein d’un réseau d’inventeurs ont une influence sur leur innovativeness. Nous avons choisi d’étudier plus particulièrement la capacité à innover des inventeurs fortement productifs en mobilisant des données sur les co-inventeurs de brevets. Une étude empirique portant sur 1157 inventeurs prolifiques français qui ont obtenu 30477 brevets sur la période 1975-2002 a donc été menée. Les résultats de la régression logistique corroborent notre hypothèse et montrent un impact significatif des collaborations répétées sur la capacité à innover des inventeurs prolifiques. / This thesis aims at studying the impact of interpersonal networks on the innovativeness of inventors. The academic literature underlined the strong relation between interpersonal networks and interpersonal cooperation. The cooperative behaviour appears as the best way to success in an innovative project, a complex project. We make here the hypothesis according to which repeated collaborations in a network of inventors have an influence on their innovativeness. We chose to study more particularly the capacity to innovate of strongly productive inventors by mobilizing data on the co-inventors of patents. We run an empirical study concerning 1157 French prolific inventors who obtained 30477 patents over the period 1975-2002. The results of the logistic regression confirm our hypothesis and show a significant impact of repeated collaborations on the capacity of prolific inventors to innovate.

Model Stirlingova motoru v PSCAD / Model of Stirling Engine in PSCAD

Gallo, Michal January 2016 (has links)
This dissertation about the Stirling engine deals with the history and formation of the heat engine. At the beginning of this work, fundamental parts and their functions are described, elucidating the principle of operation explained by the thermodynamic cycle and subsequently comparing the ideal and the real Stirling cycle and last but not least provides various modifications whilst describing their differences. The mathematical model of the Stirling engine is processed by Schmidth’s theoretical analysis and thereafter is created in PScad v46. The process of creating a model is shown in one of the chapters of this dissertation. The results were taken into account in the design of 3D models in Inventor Professional by Autodesk. The work concludes with the evaluation of the computational model and its functionality as well as the documentation of the 3D model.

Principal Leadership, Teacher Morale, and Student Achievement in Seven Schools in Mitchell County, North Carolina.

Houchard, Morgen A. 17 December 2005 (has links) (PDF)
The purpose of this study was to understand and measure principal leadership practices and teacher morale as it relates to student achievement in Mitchell County at two elementary schools, four middle schools, and one high school. First, a review of the related literature attempted to define teacher morale as much as possible given that it is an ever-changing individual characteristic. Second, the researcher tried to understand teacher morale and distinguish between high and low elements and characteristics of teacher morale. Third, the researcher examined the difficult task of measuring the morale of teachers in public education today. Fourth, an attempt was made to understand what role school leaders play in the development of teacher morale and how their specific behavior affects the morale of teachers. Lastly, student achievement was reviewed using the North Carolina End-Of-Grade tests. All of these variables were examined to determine if there was a connection or pattern to high or low student achievement based on teacher morale. This quantitative study was conducted using a survey-design method. The Purdue Teacher Opinionaire was used to measure factors contributing to teacher morale. The Leadership Practices Inventory (LPI) was chosen to measure leadership practices that best supports great accomplishments in organizations. The North Carolina End-Of-Grade/End-Of-Course tests were used to measure student achievement. Overall results for Mitchell County Schools showed that there was a moderately high level of teacher morale. Satisfaction with teaching led the way in contributing to higher morale whereas the issue of teacher salary was found to lower morale. School leaders in Mitchell County proved to inspire a common vision as well as encourage teaching from the heart more so than found in existing research. Teachers from two of the seven schools rated their principals higher in leadership practices than the principals themselves; this is contrary to presented research. Many significant relationships existed between perceived leadership practices and teacher morale factors. All factors of teacher morale as measured by the Purdue Teacher Opinionaire had a positive correlation with the End-Of-Grade/End-Of-Course test scores.

Patent ownership : rights to employee inventions

McBride, Vanessa Ann 11 1900 (has links)
A patent is an intellectual property right granted as a reward for the labours of the inventor so as to commercially exploit the invention in return for disclosure of the invention. The benefits of the patent system find perfect expression in the employment situation since the employer is better equipped to exploit the invention through provision of resources and capital whereas the employee is provided with an opportunity to develop his technical know-how. A comparative study of the laws pertaining to employee inventions in the United Kingdom, Federal Republic of Germany and the United States of America reveals a variety of approaches to the subject of employee inventions. The approach of the South African law on the subject is inadequate and legal reform is a necessity. The recommendations for such reform encapsulates a blend of the best features of each of the three national approaches to employee inventions. / Mercentile Law / LL. M. (Law)

Exploitation of University-Based Healthcare Innovations : The Behaviors of Three Key Actors and Influencing Factors

Brantnell, Anders January 2017 (has links)
Large resources are invested in healthcare research, but despite this there is a wide gap between research knowledge and healthcare practice. Implementation researchers have addressed this gap, focusing mostly on the role of healthcare practitioners. However, a narrow focus on implementation does not take into consideration the preceding stages and the roles of different actors during the whole innovation process, which starts from research and ends with implementation. The aim of this thesis is to examine the behaviors of three key actors during an innovation process and to explore the influence of selected contextual factors on their behavior. Study I (n=10 funders) identifies several facilitative roles for funders and suggests that implementation risks becoming no one’s responsibility as the funders identify six different actors responsible for implementation, the majority of whom embody a collective or an organization. Study II finds that the implementation knowledge of Swedish funding managers (n=18) is mostly based on experience-based knowledge. The majority of the funding managers define implementation as a process and express limited knowledge of implementation. The findings of Study III (n=4 innovation cases) show that the roles and involvement of academic inventors and ISAs (innovation-supporting actors) are more connected to intellectual property (IP) nature than to intellectual property rights (IPR) ownership. Study IV (n=4 innovation cases) identifies three different logics that influence the behavior of academic inventors: market, academic and care logics. A pattern emerges where the behavior of academic inventors is guided by a unique logic and there is no interaction between logics, despite the existence of multiple logics. The individual strategies to handle multiple logics coincide with the influence of logics. In addition, IP nature, distinguishing between high-tech and low-tech innovations, is connected to the influence of institutional logics: low-tech connected to the care logic and high-tech connected to the market logic. This thesis has three main theoretical and practical implications relevant for practitioners, policymakers and researchers. First, implementation responsibility is an important issue to study and discuss, because without clearly defined responsibilities and management of responsibilities, responsibility might become no one’s responsibility. Second, the finding that experience-based implementation knowledge contributes heavily to policymakers’ knowledge encourages further studies and discussions regarding this relatively neglected issue. Third, the importance of IP nature in shaping innovation processes should be considered and further examined, not only as a factor influencing inventors and ISAs’ roles and involvement, but also as influencing the prevalence of different institutional logics. Further, the relevance of a distinction between low-tech and high-tech IP should be reflected on.

台灣IC產業專利發明人的合作網絡機制 / Innovation Mechanisms of the Patent-Based Inventor Networks in Taiwan IC Industry

官逸人, Guan, Yi Ren Unknown Date (has links)
IC(積體電路)產業是台灣過去三十多年來發展最完整、且在世界上最具有競爭力的創新型產業。研發與技術專利成長快速,也代表這個產業的技術創新成果。台灣IC 產業技術創新和專利的研究累積了一些成果,但較缺乏使用研發創新發明人網絡所做的分析。本研究使用IC 產業專利發明人網絡資料,從結構洞(structural holes)和地位訊號(status signal)這兩個過去西方半導體和生物科技等創新產業研究中,最能解釋創新行動者與網絡系統和創新表現理論機制的學術研究累積成果出發,並反省台灣特有IC 產業分工技術利基位置、流動型勞力市場,發展出專利發明人網絡對專利發明成果影響機制之模型。研究發現,分析結果支持發明人地位訊號、結構洞網絡理論機制有助於專利創新發明的假設。而比較特殊的例外是,上游的專利發明網絡,結構洞低的類型反而有比較好的專利創新。這是由於上游的IC設計產業技術特性,需仰賴同一團隊的人重複合作方能完成設計,所以大多與重疊的人合作,結構限制較高,因此呈現與結構洞理論不同的情況。此外,研究發現,流動並不一定帶來較佳的技術創新,台灣IC產業專利人才流動對於技術發展與創新的正面影響,較多是在上游的IC設計產業。 因此創新發明鑲嵌在台灣特有半導體的不同技術利基環境中,還必須考慮到不同產業位置的技術特性,與產業技術發展所在的階段,才能正確解釋台灣IC產業的創新發明機制。 / The IC (integrated circuit) industry has been the most complete, competitive and innovative industry in Taiwan over the past three decades. The rapid growth of patents in this field demonstrates the marvelous outcomes of technological innovations. A huge amount of patent-based research has been accumulated in this industry, but only a little is related to the inventor network. Structural holes and status signal are two competing perspectives in explaining the dynamic mechanisms between innovative actors and network systems of the most innovative industries, semiconductor and biotechnology, in advanced countries. We use these two theories and network data of patent-based inventors to discuss the specific niche of vertical disintegration and fluid labor market in Taiwan IC industry, and develop models on mechanisms of how inventors’ networks affect the outcome of inventors’ patents. The findings reveal that the hypothesis on the effects of status signals and structural holes in inventors’ collaboration networks on the citations of inventors’ patents was supported. However, the patent inventions of the upstream IC design firms, the collaborative invention teams seem to be small or high structural constraints. Most of the patents of these newly growing firms in IC design industry are specialized in consumption products. The structural constraints are high, but the impact of is large. Besides, inventors’ fluidity would not necessarily create more influential patents. The fluidity of patent-based inventors was positive impact to the patent inventions, more was found in the IC designs company. The IC industry has been vertically differentiated into three sectors: the IC designs, the IC foundry, the package and test. In principle, these three sectors demand different levels of technology. The maturity of technological niches will affect the impacts of the patents.

從作者與發明人的關係探討技術發展各階段論文與專利活動之關聯性──以電腦視覺領域之賈伯濾波器技術為例 / Discovering the Relationship between Publishing and Patenting Activities from the Relatedness of Authors and Inventors over the Life Cycles of Technological Development── Case Study of Gabor Filter in Computer Vision

許舜棋, Hsu, Shun Chi Unknown Date (has links)
在技術快速變遷的環境中,如何迅速掌握與研發相關的情報以協助研發決策的制訂,已經成為企業重要的競爭優勢來源。近年來,由於電腦運算能力的快速提昇,使用電腦輔助企業自動、快速地從大量增加的科技資訊(特別是專利和論文)中淬取出攸關的資訊,就成為了近年來產業界和學術界積極研究的目標。 在眾多方法中,使用書目計量分析和專利分析方法是最引人注目的方法之一。使用書目計量分析和專利分析可以從龐大的論文和專利資訊中,快速瞭解科技發展的動態:包括瞭解科技發展的階段為何,熱門的科技領域為何,重要的作者和企業為何等等。然而,現階段的書目計量分析和專利分析雖然可以協助瞭解科技發展的全貌,對於科技發展下技術發明活動與科學研究活動的關聯性,以及不同的科技發展階段裡發明人和作者的動態關係,卻仍然缺少相關的研究。 因此,本研究提出以下三點研究問題: 1. 不同類型的論文作者和專利發明人的科學研究/技術發明活動,與技術發展階段的關聯性為何? 2. 發明作者的技術發明/科學研究活動與一般發明人或作者的差異為何? 3. 發明作者的技術發明活動與科學研究活動關係為何? 針對以上的研究問題,本研究首先通過回顧相關文獻以建立分析發明人和作者的研究架構,再蒐集專利和論文的資料並依照架構的需要處理資料,最後進行分析與討論以得到研究結論。 本研究主要獲得以下三點研究結論: 1. 天才發明人是技術發展處於萌芽期時專利發明的要角,而關鍵發明人大多在技術發展進入成長期時才投入專利發明。至於頂尖作者,則在技術發展的萌芽期、成長期和成熟期都是論文發表的要角。 2. 關鍵發明人有很高的機會是頂尖作者,而發明作者如果不是關鍵發明人,則其專利發明的表現有略高的機會較其他發明人更差。 3. 大部份發明作者的專利發明活動在論文發表活動之後;但是關鍵發明人則較傾向先申請專利,再發表主題高度相關的論文。 / Mining information to improve corporate R&D decision making had been an important source of competitive advantage in the rapid changing technological environment. Recently, extracting relevant information quickly and automatically from massive amount of technological data (especially patent and scientific publications) with the aide of computer had become an active research area for both industrial and academic researchers due to ever-growing computing power. Among the methods of retrieving technological information, bibliometrics and patent analysis are two of the most attractive ones. Bibliometrics and patent analysis provide a quick way to capture the dynamics of technological development, including the stage of technological development, active technological research area and important researchers/corporates, etc. Although bibliometrics and patent analysis are helpful to understand the landscape of technological development, there still lacks researches about the relationship between scientific invention and research activities as well as the dynamics between patent inventors and publication authors along different stages of technological development. Hence, this research raises the following questions: 1. What is the relation between scientific research/invention activities and technological development stages for different categories of publication authors and patent inventors? 2. What is the difference of scientific research/invention activities between Inventor-Authors and other inventors/authors? 3. What is the relation between scientific research and invention activities of Inventor-Authors? This research reviews related researches to define a research framework connecting authors, inventors and technological development stages. Then patent and publication data are collected and processed based on the research framework. This research conclusion is made after analysis and discussion. Conclusion of the research includes the followings: 1. "Talent Inventors" play important role when the technological development is in "Emerging" stage, and "Key Inventors" starts patent inventions after the technological development enters "Growth" stage. "Top Authors" play important role across "Emerging", "Growth" and "Maturity" stages of technological development. 2. "Key Inventors" are more probable to be also "Top Author". "Inventor-Authors" who are not "Key Inventors" are more probably to perform worse than other inventors. 3. Most "Inventor-Authors" apply for patents after papers of highly related topics are published. But "Key Inventors" tend to apply for patents before papers of highly related topics are published.
