Michelle Obamová jako první dáma: Případová studie / What type of First Lady Was Michelle Obama: Case Study on Michelle Obama as First Lady

Matějčková, Anna January 2019 (has links)
This Master's Thesis analyzes various roles that First Ladies of the United States take upon when their spouses are elected President of the United States. Even though the role of First Ladies is undefined, the public still expects a certain level of manners and dedication to their selected causes. The influence of First Ladies is, on the one hand limited by the fact that they do not have any real policies to follow. On the other hand, the platform of First Ladyship offers a great deal to influence and ability to raise awareness to causes they care about. The main argument is that Mrs. Obama had a particular skill to promote her initiatives and to turn negative attention by the media to the rights directions. Additionally, she was able to get the attention of corporations and state officials to help her make a real impact on her initiatives. Her authenticity and fun engaging style helped her with engaging young people into her campaigns and her status of popular First Lady. Therefore, the goal of this thesis is to find out how the role of First Lady changed during Michelle Obama's term as First Lady and what kind of influence her initiatives brought. Finally, the analyses shows that Michelle Obama was a very active First Lady that pushed the role of the First Lady forward. Her well though...

Innovation and Collaboration networks: Assessing knowledge pipelines, knowledge flows and firm performance

Shauchuk, Palina 24 September 2020 (has links) (PDF)
In this introductory Chapter the rationale for this research is explained and an overview of the thesis is provided. This chapter serves as a concise introduction to the subject of the knowledge base and knowledge pipelines in a metropolis as Brussels, as well as providing an insight into the policy driven empirical research with additional focus on the appropriate spatial level of analysis to highlight the spatial inequality of innovation. The objectives of the thesis are reviewed by giving an overview of the research questions and the main hypotheses related to them. The theoretical background used in this thesis is briefly outlined. The structure of the thesis can be summarised as follows. The second chapter provides basic information about data on patents and scientific publications, the construction of indicators based on patents and scientific publications, as well as guidelines for the compilation and interpretation of patent and scientific publication indicators. The third chapter focuses on the determinants of the efficiency levels across regions in Belgium at different spatial levels. The fourth chapter builds on the research made in the previous chapters and focuses on the analysis of the impact of patent collaboration networks on the output growth of R&D active companies in Belgium. The fifth chapter analyses the impact of different collaboration ties on the productivity of innovative companies in Belgium, measured in several ways through the innovation survey and in terms of patents. The conclusion reported in the last chapter summarises the main findings and highlight possible suggestions for future research. / Benchmarking exercises are increasingly used as an assessment instrument to guide policy-makers. They contribute to policy-making in three broad ways: delineating and monitoring development and progress; facilitating the exchange and gathering of knowledge on practices and policies; and promoting the image and attractiveness of economies. This research complements existing information about the Brussels Regional Innovation System (BRIS) with additional data that is less frequently available through current channels or difficult to make public due to the number of data manipulations. This research illustrates the Brussels innovation system by focusing on various aspects related to intra- and interregional connections. The dataset is based on scientific publications and patents over the period 1993-2013 containing at least one author with an affiliation or one inventor located in the Brussels-Capital Region, Vienna and Berlin. Patents and scientific publications provide a clear picture of the nature of technological change and innovation. Moreover, these sources give some further indication of R&D activities in the field and the position and specialisation of countries. The main benefit of such indicators is the unique empirical characterization they provide of the way actors interact as a collective system of knowledge production and diffusion (OECD, 1996). The main objective of this work is to compare Brussels with Belgian regions, city agglomerations and districts, as well as with capital cities of metropolitan regions (Vienna and Berlin) in terms of patenting and producing scientific publications, in order to map and understand how knowledge exchange takes place when Brussels actors are involved and which partners, locations, scientific fields and technological sectors are preferred. The main focus is on providing basic information about patent and scientific publication data, the construction of indicators based on patents and scientific publications, as well as guidelines for the compilation and interpretation of patent and scientific publication indicators. / The topic of the spatial pattern in R&D activities was investigated by several scholars. It is worthwhile to explore the dynamism and change of R&D activities’ spatial spread as R&D activities are very much a dynamic phenomenon and the consequences in terms of past growth of these activities have painted the current relative position of the regions. Analysing the determinants of the efficiency levels across Belgian regions at different spatial levels (3 regions, 10 provinces, 43 districts, and city agglomerations), we derive a regression based on the measurement of regional output growth by estimating an extended Cobb-Douglas production function based on a representative sample of Belgian R&D active firms over the period 2000-2013. We investigate the role played by knowledge (private and public R&D stocks) on the output growth by applying spatial econometric methods that account for both heteroscedasticity and spatial autocorrelation. The chapter focuses on the comparison of obtained results with previous studies based on Belgium. It turns out that a large part of output growth differences across the Belgian regions are explained by disparities in the endowments of these determinants. / Although the literature on the relations between patents and output growth of R&D active companies has been widely investigated, there has been little research with respect to the impact of patent collaboration networks on the output growth of R&D active companies. Integrating theoretical developments from the literature, we propose and test a conceptual framework that allows us to explain to what extent patent collaboration networks affect output growth. Testing the framework by using a constructed company-level dataset for Belgium, the empirical analysis reveals that output growth is significantly influenced by patenting activities and by collaborative relations with respect to patents. The chapter focuses on two distinct spatial levels. First, the spatial reach of the patent collaboration network is considered. The findings show that output growth is higher when collaborative relations are internationally oriented. Second, the regional location of the company shows differences in patenting activity, patent collaboration, and the spatial reach of the patent collaboration network. / Inter-organisational relations are a crucial aspect of knowledge flows, which are at the same time an important engine for innovation. Collaboration has become an ever more important feature of entrepreneurial strategy to innovate. Network ties facilitate companies’ innovative capabilities by acting as key sources for innovations, helping to access the resources and boosting knowledge transfer. This chapter analyses the impact of different collaboration ties on the productivity of innovative companies in Belgium, measured in several ways through the innovation survey (Community Innovation Survey) and in terms of patents (Patstat). Patent statistics are used as an objective measure for innovation. Unlike patent data, innovation surveys measure innovation activities carried out in companies. This chapter is primarily concerned with the following research question: do collaboration networks, as measured by innovation surveys (CIS database) and by invention applications (Patstat database), impact productivity growth in the same way? Further, this chapter focuses on an alternative spatial approach in order to look into the role played by proximate and distant inter-organisational networks among organisations. The findings show that the collaboration ties between companies are contributing the most to productivity growth followed by collaboration ties involving universities and government, public or private research institutes. Second, the spatial reach of the inter-organisational networks shows divergent impact on productivity performance of innovating companies. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished

生物科技專利延展性申請專利範圍之研究 / Studies of Reach-Through Claims in Biotechnology Patents

蕭偉文, Hsiao, Wei Wen Unknown Date (has links)
生物科技之專利對於生物科技產業之重要性更是不可言喻。由於生物科技發展之特性,例如:高度不確定性、研究週期長、投資成本高等因素,許多發明人在申請生物科技專利時,都試圖擬定較廣泛的申請專利範圍。「延展性申請專利範圍」(reach-through claims)為基於目前專利說明書揭露之內容來涵蓋所有「未來」可能衍生之產物;或是某特定化合物尚未被確認前,試圖藉由一個上游基礎研究「先驅型發明」之申請專利範圍擴大延展至下游後續發明之商業產品,這非但會箝制技術後續之發展,更可對已存在之先前技術主張侵權,影響範圍極廣。從2004年University of Rochester v. G.D. Searle案 和2010年Ariad v. Eli Lilly案 ,美國聯邦巡迴上訴法院皆認為「延展性申請專利範圍」無效,歸因於專利內容未清楚揭露而不符合美國專利法第112條第1段中所規定的「可據以實施性」和「書面說明要件」。2013年德國聯邦最高法院對同是屬於「延展性申請專利範圍」之Probiodrug案與前述兩件美國相關判例有分歧之見解和判決。有鑑於此,本文以比較法觀點分析國外相關判例及實踐標準,全面性針對生物科技領域「延展性申請專利範圍」問題進行探討,嘗試建立一最適的法律模式,並期許未來可作為我國對其相關法制與解決方案之參考依據。

Predictive gaze in action selection within virtual reality

Bampouni, Elpida January 2020 (has links)
The human gaze is pivotal in motion planning and control. Gaze is typically directed at visual target sites prior to physical interactions with them. This proactive gaze (PEG) behavior has been observed in a multitude of physical situations. However, PEG has not been examined in virtual reality (VR). Identification of PEG in VR could be helpful for digital human modeling applications and human-robot interactions. In this study we asked 10 participants to perform a pick-and-place (PAP) task in VR while we were tracking gaze behavior. Our results indicate that PEG also occurs in VR. Furthermore, the action to reach directly towards the PAP object or walk to it before reaching, results in different gaze strategies. Relocating before a reach is associated with gaze to additional sites, such as the floor and the table upon which the object was placed. / Den mänskliga blicken är avgörande för planering och kontroll av rörelse. Blicken riktas vanligtvis mot visuella mål före interaktion med dessa. Denna proaktiva blick (eng. ’proactive gaze’; PEG) har observerats i många olika slags fysiska situationer. Dock har inte PEG undersökts i virtual reality (VR). Identifiering av PEG i VR skulle kunna vara användbart för applikationer med digital mänsklig modellering och människo-robotinteraktioner. I denna studie instruerade vi 10 försöksdeltagare att utföra en s.k. pick-and-place-uppgift (PAP) i en VR-miljö medan vi registrerade deltagarnas blick. Våra resultat indikerar att PEG också förekommer i VR. Vidare leder handlingen att direkt sträcka sig efter objektet till ett annorlunda blickbeteende jämfört med att först förflytta sig innan man sträcker sig efter PAP-objektet. Vid förflyttning innan man sträcker sig efter objektet fästs blicken på ytterligare områden såsom golvet och bordet som objektet placerats på.

Design and fabrication of a photonic integrated circuit comprising a semi-conductor optical amplifier and a high speed photodiode (SOA-UTC) for >100 Gbit/s applications / Etude d'un récepteur pré-amplifié de type PIC (Photonic Integrated Circuit) réalisé par intégration monolithique d'un amplificateur (SOA) optique à semi-conducteur et d'une photodiode (UTC) pour les liaisons courtes distances à 100 Gbit/s et au delà

Anagnosti, Maria 13 November 2015 (has links)
Ce travail porte sur la conception, la fabrication et la caractérisation d’une photodiode très haut débit (UTC PD) et son intégration avec un préamplificateur optique à semi-conducteur (SOA) pour les liaisons optiques à courte distance à 100 Gbit/s en bandes C et O. Il porte également sur la conception d'un duplexeur (Tx / Rx) avec liaison montante en bande C et liaison descendante en bande O. L'intégration monolithique d’un SOA avec une photodiode haut débit sans filtre optique entre les deux présente des avantages majeurs parmi lesquels: - Augmentation de la distance de transmission. - Augmentation du nombre d'utilisateurs connectés. - Diminution des coûts globaux de fabrication incluant l’assemblage. La première partie de cette étude porte sur l'optimisation SOA pour un fonctionnement à forte puissance (Psat). Un faible facteur de bruit (NF) et une faible dépendance à la polarisation (PDL) sont requis pour les récepteurs préamplifiés. De plus, un fonctionnement du et opérer en régime linéaire est nécessaire pour les schémas de modulation complexes. Le SOA actuel possède un gain de 18 dB avec un facteur de bruit de 8 dB, une faible PDL (<2 dB), et une bonne puissance de saturation en entrée (-8 dBm). Grâce à l’optimisation de la structure verticale du SOA et de son couplage avec la fibre les performances attendues sont améliores : Psat >-5 dBm, NF <8 dB, PDL et gain similaire. D'autre part, les interconnexions électriques de la photodiode ont été optimisées ce qui a permis de démontrer des photodiodes avec une bande passante supérieure à 100 GHz. Les photodiodes présentent un fort coefficient de réponse (R) (0,6 A/W à 1,3 μm et 0,55 A/W à 1,55 μm) et une faible PDL <1 dB. Un fort courant de saturation de 14 mA à 100 GHz a aussi été démonté. Enfin, la caractérisation des SOA-UTC réalisés a montré simultanément une très forte responsivité (95 A/W), une faible dépendance à la polarisation PDL (<2 dB), un faible NF (8 dB) et une large bande passante à 3 dB (> 95 GHz), qui placent nos composants au meilleur niveau de l’état de l’art avec un produit gain-bande record de 6,1 THz. Les Mesures numériques à 64 Gbit/s montrent que notre récepteur atteint une sensibilité de -17 dBm pour un taux d'erreur de 10-9, et la sensibilité attendue à 100 Gbit/s est de -14 dBm / This work focuses on the design, fabrication and measurements of a uni-travelling carrier high speed photodiode (UTC PD) and its integration with a semiconductor optical preamplifier (SOA) for short reach 100 Gbit/s optical links, in O- and C- bands. This work also focuses on the design of a duplexer (Tx/Rx) with downstream in O-band and upstream in C-band. The SOA monolithic integration with a high speed PD without an optical filter in between yields major benefits among which: - Increase in the transmission distance. - Increase in the split ratio correlated to the number of connected users. - Decrease of the overall fabrication and assembling cost. The first part of this work is dedicated to optimizing the SOA for high power operation (Psat). The low noise figure (NF), and polarization dependence loss (PDL) are critical parameters for a preamplified receiver. Also complex modulation formats require linear gain regime of the SOA. The current SOA presents 18 dB gain with NF (8 dB), low PDL (<2 dB), and good input power saturation (-8 dBm). Thanks to further optimization of the SOA vertical structure and coupling with the optical fiber, the expected SOA performance is higher Psat >-5 dBm, NF <8 dB, similar PDL and gain. Secondly, the electrical interconnects of the photodiode is optimized to increase the photodiodes’ bandwidth, which allows to demonstrate photodiode with >100 GHz bandwidth. The PD presents high responsivity (R) (0,6 A/W at 1,3 μm and 0.55 A/W at 1,55 μm) and low PDL <1 dB. Also the saturation photocurrent is high (14 mA at 100 GHz). Finally, the SOA-UTC demonstrates high responsivity (95 A/W), low PDL (<2 dB), low NF (8 dB) and a wide 3 dB bandwidth (>95 GHz), which yields a record gain-bandwidth product of 6.1 THz. Large signal measurements at 64 Gbit/s show that our receiver reaches a low sensitivity of -17 dBm for a bit error rate of 10-9, and is expected to reach -14 dBm at 100 Gbit/s
