Overall synthesis and conclusions
No full textThis chapter first systematically summarizes the most important findings and policy implications of each of the chapters included in this book volume. Next it synthesizes the overall findings and policy implications, and discusses future avenues for policy making and research. A first conclusion is that the chapters make clear that the ranges in policy relevant implications of AVs, within the scope of each chapter/topic, are still relatively broad. Secondly we conclude that research that is conceptually rich is more valuable for policy making. Thirdly we hypothesize that context matters for the uptake, impacts, and specific system design characteristics of real world AV implementation. Fourth we conclude that research on the global south has been limited so far. Fifth we argue that AVs, shared vehicles and electric vehicles (EVs) might stimulate each other in a positive way, in all directions. Finally we conclude that AVs will have wider societal implications, such as in the area of land use, accessibility, social exclusion, governmental expenditures, the labor market, and the environment. The more indirect the effects of AVs are, the more difficult they are to understand. For policy making a first conclusion is that the issues of ethics, cyber security and data protection deserve way more attention than they currently get. We also conclude that future motorway network extensions might not be no-regret anymore, because of possible congestion reductions due to AVs, but also because of decreasing marginal values of time. Finally we argue that countries that introduce AVs later than other countries can learn a lot from the real world experiences elsewhere.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Logistic
Post hos nostra terra est: mapping the Late Roman ecumene with the Expositio totius mundi et gentium
No full textThis paper studies the landscape of the Late Roman ecumene as depicted by the Expositio totius mundi et gentium (Expos. mundi),1 written by an anonymous author in the middle of the 4th century CE. It will first contextualise the text and assess its structure, language and genre. The contribution will then focus on the distinction between Rome, the Sasanids and utopic societies in the east near Eden, the political and military organization of the Imperium Romanum as well as its economic framework and varying expressions of its culture. As
this paper will show, the anonymous author does not present detailed descriptions of Rome’s geographical landscape. Instead, the primary focus is on material resources of the Roman Empire, their potential for economic exploitation and the trading opportunities resulting from it. Rome’s cultivated landscapes are thereby regarded as important preconditions for its success on an economic, political and cultural level
Walking as Do-It-Yourself Urbansim
No full textThis article develops a series of theoretical notions arising in the context of an urban art project that took place in London in the summer of 2004 under the title “Where do you breathe?”1 As a participatory urban intervention, the project challenged the notion of authorship in public space by casting the act of walking as a transformation of urban space, and examined the potentials for a practice of photography based on interaction rather than passive representation

Policy implications of the potential carbon dioxide (CO<sub>2</sub>) emission and energy impacts of highly automated vehicles
No full textThis chapter explores the extent to which the adoption of highly automated vehicles (AVs) will lead to carbon dioxide (CO2) emission reduction in the future. Additionally, policy implications are given. Based on existing literature, this chapter shows that the adoption of AVs will result in a modest improvement of CO2 emission per kilometer traveled compared to non-autonomous vehicles in the future. Combined with the expectations that AVs will lead to a modest to, even, high growth in vehicle kilometers traveled (VKT) compared to business as usual, the net energy and CO2 emission balance for AVs seems, at its best, to be neutral, but is probably negative. The potential accelerating role of AVs in relation to the uptake of electric vehicles might have the largest positive impacts on the CO2 emissions per kilometer driven, but this accelerating role of AV technology in relation to the uptake of electric vehicles is uncertain. For the time being the most useful policy implication to curb road transport CO2 emissions seems to be to continue with policies that promote the use of alternatives for fossil fuels, such as electricity.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Logistic
Creativity in co-Design for Physical Education: Comparing Contributions of Children and Professionals
No full textThis study is carried out within the context of a research and innovationproject Co-design with Kids that aims to support teaching of broad so-called ‘21stcentury’ skills. In this project, design toolboxes for use within primary educationare developed and studied, with real life clients and assignments. In the casedescribed in this paper, the assignment was to create new concepts for physicaleducation (PE). To be able to assess the value of design outcomes created in aco-design trajectory by children, we compared their design outcomes to thosecreated in a similar design process by professionals. Six teams of children (n=21,11-12 years old) and three teams of professionals (n=10, with a background indesign, sports or physical education) developed concepts in separate co-creationsessions. We present a first assessment of the differences and similarities increativity of the design outcomes of the two groups. This assessment of textualsummaries shows no remarkable differences between design outcomes ofchildren and those of professionals in terms of elaboration, originality andrelevance. This indicates that children could be involved as design partners.Further research is needed to gain insight into the specific value of involvingchildren as design partners.Accepted author manuscriptDesign Conceptualization and CommunicationScience Education and Communicatio
A biopolítica como a política da vida e da vitalidade humana : aproximações, discrepâncias, comensurabilidades e avanços conceituais nas propostas de Michel Foucault e Nikolas Rose
No full textThis Master's Dissertation proposes to analyze the notion of biopolitics and its derived concepts as conceptualized, in the 1970s, by the French philosopher Michel Foucault. At the same time, it also intends to analyze the same notion, biopolitics, proposed in the first decade of the 21st century, by the English sociologist Nikolas Rose. Both approaches have their own characteristics. Biopolitics theorized by Michel Foucault refers to the entry of life into the political strategies of States, which occurred between the 17th and 18th centuries, when sovereign power assumed the role of managing the life and vitality of man-species, aiming to, above all, to increase the population’s level of health. The conception of biopolitics formulated by Nikolas Rose concerns the politics of life that has taken shape in the last three decades. It is not delimited by the poles of health and illness, it is concerned with optimizing human vitality and is put into practice by social actors themselves in conjunction with medical authorities. Furthermore, 21st century biopolitics is related to the formation of social relations based on shared somatic statuses. This research seeks, through Content Analysis, to identify the approximations, discrepancies and advances in relation to these concepts from one author and the other, enabling us to draw a parallel between the biopolitics defined by both authors. The results point to the coexistence and specific complementarities between the two notions of biopolitics.A presente Dissertação de Mestrado busca analisar a noção de biopolítica tal como conceituada, na década de 1970, pelo filósofo francês Michel Foucault e, na primeira década do século XXI, pelo sociólogo inglês Nikolas Rose.

A biopolítica teorizada por Michel Foucault refere-se a entrada da vida nas estratégias políticas dos Estados, o que se deu entre os séculos XVII e XVIII, quando o poder soberano assume o papel de gerenciar a vida e a vitalidade do homem-espécie, objetivando, sobretudo, aumentar o nível de saúde da população. A concepção de biopolítica formulada por Nikolas Rose diz respeito à política da vida que tomou forma nas últimas três décadas. Ela não está delimitada pelos polos da saúde e da doença, está preocupada com a otimização da vitalidade humana e é posta em prática pelos próprios atores sociais em conjunto com autoridades médicas. Além disso, a biopolítica do século XXI está relacionada à formação de relações sociais a partir de status somáticos partilhados.

RF phase modulation of optical signals and optical/electrical signal processing
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2006.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 125-127).Analog RF phase modulation of optical signals has been a topic of interest for many years, mainly focusing on Intensity Modulation Direct Detection (IMDD). The virtues of coherent detection combined with the advantages of Frequency Modulation, however, have not been explored thoroughly. By employing Frequency Modulation Coherent Detection (FMCD), the wide optical transmission bandwidth of optical fiber can be traded for higher signal-to-noise performance. In this thesis, we derive the FM gain over AM modulation -- the maximum achievable signal-to-noise ratio (by spreading the signal's spectrum) for specific carrier-to-noise ratio. We then employ FMCD for a scheme of remote antennas for which we use optical components and subsystem to perform signal processing such as nulling of interfering signals. The performance of optical processing on different modulation schemes are compared, and some important conclusions are reported relating to the use of conventional FMCD, FMCD with optical discriminator (FMCD O-D), and IMDD. Specifically, the superiority of conventional FMCD is shown; and, on the other hand, the inferiority of FMCD O-D is shown (same performance as IMDD) because of the use of an O-D. Finally, the remote antenna scheme is generalized for N antennas and N users.by Nikolas I. Andrikogiannopoulos.S.M
The Effectiveness of MBSR on the Occupational Stress of Correctional Officers
No full textThis dissertation looks at the negative effects of the work environment and other factors related to correctional officers lived experience. The intervention concentrates on the effect of mindfulness-based stress reduction on the occupational stress of correctional officers. Correctional officers have always dealt with difficult work conditions, but over the last 30 years the increase in the number of incarcerated people, the lack of retention among correctional officers, and the proliferation of inmates with complex mental health issues and gang affiliations have all created a much more complex and dangerous work environment. Combine this with the new understanding of the effects of stress on correctional officers’ health and quality of life and the need for improved coping and training for them has become extremely important. One intervention that has gained prominence in many areas is the discipline known as mindfulness-based stress reduction. This hybrid based on the ancient arts of yoga and meditation has been brought int Western culture by John Kabot Zinn among others. It has been proven to have dramatic effects on a person’s ability to deal with stress, chronic pain, and other health issues. This dissertation proposed that the use of online mindfulness-based stress reduction classes could have a positive impact on correctional officers’ ability to deal with occupational stress. Utilizing the Occupational Stress Index-Revised for pre and post testing the results did not provide significant results
