Stress engineering of boron doped diamond thin films via micro-fabrication
No full textIn this paper, a novel approach is presented to tailor the stress properties of diamond thin films via boron doping and micro-fabrication of bridges using focused ion beam milling. The experimental data, based on detailed confocal micro-Raman investigations, are supported and interpreted through finite element method calculations of the stress distribution at mechanical equilibrium. These results indicate that appropriate design of microbridge geometries, together with boron doping, would allow the material stress to be largely enhanced or diminished compared to non-patterned thin films. Our approach, together with a deterministic incorporation and positioning of diamond color centers, may open novel opportunities to tailor the optical and spin properties of diamond-based quantum devices through stress engineering
Jewish hydra, German Heimat, and ‘the Jewish question’: Judaism and subjectivity in Lazarus Bendavid, Berthold Auerbach and Karl Marx
No full textThis dissertation examines aspects of the Jewish encounter with modern discourses of subjectivity. The project follows three interventions into discourses of Jewish subjectivity, two by Jewish authors who grapple with the question of how to speak as Jews in the modern German context, the third a discourse of radical social critique that strategically deploys flagrantly anti-Semitic stereotypes. Chapter One examines Lazarus Bendavid\u27s caustic pamphlet On Jewish Characteristics of 1793; Chapter Two explores the early career of Berthold Auerbach from his first literary activity until his breakthrough into literary stardom as a Heimatdichter with his Black Forest Village Stories of 1843; and Chapter Three investigates the function of Jewish figures in Karl Marx\u27s 1843 “On the Jewish Question” and The Holy Family of 1845 and compares Marx\u27s rhetorical construction of “real Jews” to his treatment—in part invention, in part discovery—of the proletariat. Highly politicized discourses on subjectivity proliferated in Germany in the period between the French Revolution of 1789 and the failed revolution of 1848. In this climate, Jews and Judaism became a privileged discursive site for interrogating subjectivity with the political imperatives this interrogation implied. The nexus of discourses on Judaism and subjectivity differed substantially in the two moments examined. Within Bendavid\u27s Kantian paradigm, the universal subject was essentially isomorphic with humanity at large as a moral-political community, and the “Jewish question” (avant la lettre ) was about the deficient yet potentially redeemable subjectivity of the Jew. The Young Hegelian social ontology of the self that was important for both Auerbach and Marx in the 1830\u27s and 40\u27s understood subjectivity as an obstacle to the realization of collective humanity. Each chapter explores the figuration of Jews as discursive objects in the works of the chapter\u27s central author and in key intertexts. I also investigate the three central authors from the standpoint of a problematics of enunciation. That is, I ask not only how each author speaks about Jews, but also how he does so in order to authorize his own speech. Bendavid and Auerbach each speak as a certain kind of Jew in a cultural and discursive field that made Jewish speech a treacherous undertaking. Marx deploys the figure of the obscenely “real Jew” in an effort to construct a viable locus of enunciation for his radical social critique
A New Model for Equitable and Efficient Resource Allocation to Schools: The Israeli Case
No full textThis paper sets out a new budget allocation formula for schools, designed to achieve a more equitable distribution of educational achievement. In addition to needs-based elements, the suggested composite allocation formula includes an improvement component, whereby schools receive budgetary allocations based on a new incentive measure developed in this paper (Improvement in the Educational Achievement Distribution, or IEAD). The development of the budget allocation formula is demonstrated utilizing Israeli data. Large scale, nationwide data sets relating students’ academic achievement to student background variables, teacher profiles and school characteristics, were analyzed to identify appropriate needs-based formula components and to estimate their weights. The results are compared with the funding formulas currently used in Israel.school finance, formular funding, needs-based funding, schools resource allocation, Israel

Quality of life and wellbeing among HIV outpatients in East Africa: a multicentre observational study.
No full textBACKGROUND: Global health investment has reduced HIV mortality and transmission. However, little is known of patient-reported outcomes alongside ART rollout. This study aimed to measure wellbeing using patient-reported outcome measures (PROMS) among outpatients at PEPFAR-funded facilities. METHODS: In a multicentre 2 country cross-sectional study, adults attending 12 facilities in Kenya and Uganda gave self-reported data on quality of life (physical and mental wellbeing dimensions), functional and a measure of multidimensional problems (physical, psychological, social and spiritual). RESULTS: Among the 1,337 participants, multidimensional problems were more common in psychological, spiritual and social domains than in physical. In multivariable analysis using GEE to adjust for facility effect, the mental health subscale of quality of life was lower for people with limited functional status (B = -5.27, 95% CI -5.99, 1. -4.56 p < 0.001) and higher for wealthier people (B = 0.91, 95% CI 0.48, 1.33, p < 0.001). The physical health subscale of quality of life was lower for those with limited functional status (B = -8.58, 95% CI -9.46 to -7.70, p < 0.001) and those who had a caregiver present (B = -1.97, 95% CI -3.72 to -0.23, p = 0.027), higher for wealthier people (B = 1.14, 95% CI 0.65, 1.64, p < 0.001), and positively associated with CD4 count (B = 1.61, 95% CI 1.08-2.14, p < 0.001). Multidimensional problems were more burdensome for people with limited functional status (B = -2.06, 95% CI -2.46 to -1.66, p < 0.001), and less burdensome with more education (B = 0.63, 95% CI 0.25-1.00, p = 0.001) or ART use (B = 0.94, 95% CI 0.34-1.53, p = 0.002). CONCLUSIONS: Multidimensional problems are highly prevalent, and worse with declining function. Importantly, ART use does not appear to be protective for self-reported physical and mental dimensions of quality of life. Assessment and management of self-reported wellbeing must form part of HIV care and treatment services to ensure maximum benefit from ART investment
Measurement of the prompt J/ψ and ψ(2S) polarizations in pp collisions at s=7 TeV
No full textThis is the pre-print version of the final published paper that is available from the link below.The polarizations of prompt J/ψ and ψ(2S) mesons are measured in proton-proton collisions at s=7 TeV, using a dimuon data sample collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 4.9 fb. The prompt J/ψ and ψ(2S) polarization parameters λ, λ, and λ, as well as the frame-invariant quantity λ~, are measured from the dimuon decay angular distributions in three different polarization frames. The J/ψ results are obtained in the transverse momentum range 14<p<70 GeV, in the rapidity intervals |y|<0.6 and 0.6<|y|<1.2. The corresponding ψ(2S) results cover 14<p<50 GeV and include a third rapidity bin, 1.2<|y|<1.5. No evidence of large polarizations is seen in these kinematic regions, which extend much beyond those previously explored
Special issue on RFID: Towards ubiquitous computing and the Web of Things: Guest editors' introduction
No full textThe Internet of Things (IoT) is emerging as the next technological revolution and with it opens up a new research field. In particular, this new field needs to be studied in conjunction with adequate theories, design principles, and user acceptance. As such, a number of technologies become relevant and intertwined with this new trend. In particular, IoT is an effort to reach out into the real world of physical objects. In this regard, technologies like Radio Frequency Identification (RFID), short-range wireless communications, Real Time Location Systems (RTLS), and sensor networks ubiquity contribute to make IoT vision, a reality [13]. Continuous improvements in technological performance, combined with maturing applications and decreasing prices have contributed to the pervasive adoption of Automated Identification Technology (AIT) such as bar codes and RFID technology. Following its incubation period, today RFID technology adoption can be seen in various domains making its diffusion global across industries and national borders. Over the last 10 years, RFID application is witnessing a significant growth in almost each sector. RFID Item-Level Tagging (ILT) initiatives are extensively deployed in sectors such as apparel and footwear - with companies such as Gerry Weber International, American Apparel, Macy, JC Penney, and Wal-Mart leading the movement. Adoption of RFID is closely related to various concepts such as Ubiquitous computing (Ubi-comp), the Internet of Things (IoT), and Web of Things (WoT) [14], or the Web of Things and People (WoTaP) [26], or even as the Social Internet of Things (SIoT) [3]. All these concepts have in common the idea that a tagged object (non-living thing and living thing) can communicate electronically, in real time, with its environment through the global infrastructure of wireless Internet. As RFID enabled sensors and intelligence are added to physical objects, this opens up way to innovative business models in electronic commerce and transformation of modern enterprises and their relationship with their constituencies. Not only it brings about changes to the way commerce takes place, but also to the way people interact with their environment and with each other’s, and thus opening new perspectives to connect the physical world and the digital world [32]. On the other hand, effective application and adoption of these new models and technologies pose a host of research questions requiring scientific intervention. To this end, this article is expected to serve as an inspiration to raise awareness of researchers and attract their attention.Multi Actor SystemsTechnology, Policy and Managemen
