Akademische Karrierewege

Mobilität gilt allgemein aber insbesondere in der Wissenschaft als Qualifizierungsmerkmal, dessen Relevanz durch strukturelle Beschäftigungsbedingungen unterstrichen und durch mit Ortswechseln verbundenen sozialen Aufstiegen indiziert wird. In dem Beitrag werden Karrieredynamiken thematisiert, die im Feld der Wissenschaft mit individuellen, sozialen und strukturellen Einflussfaktoren in Verbindung stehen. Hier fragen wir nach dem Zusammenhang von räumlicher und sozialer (Im-)Mobilität und deren Wirkungsgeflechten. Dabei verstehen wir räumliche Mobilität nicht nur als positiv konnotierte Optionensteigerung, sondern legen den Blickwinkel zugleich darauf, inwiefern auch soziale Ungleichheiten entstehen oder verfestigt werden können. Dazu werden konzeptionelle Überlegungen auf Basis eines fortgeschrittenen Projektvorhabens vorgestellt sowie Einblicke in die geplante methodische Umsetzung gegeben

Status of a DEPFET pixel system for the ILC vertex detector

We have developed a prototype system for the ILC vertex detector based on DEPFET pixels. The system operates a 128x64 matrix (with ~35x25 square micron large pixels) and uses two dedicated microchips, the SWITCHER II chip for matrix steering and the CURO II chip for readout. The system development has been driven by the final ILC requirements which above all demand a detector thinned to 50 micron and a row wise read out with line rates of 20MHz and more. The targeted noise performance for the DEPFET technology is in the range of ENC=100 e-. The functionality of the system has been demonstrated using different radioactive sources in an energy range from 6 to 40keV. In recent test beam experiments using 6GeV electrons, a signal-to-noise ratio of S/N~120 has been achieved with present sensors being 450 micron thick. For improved DEPFET systems using 50 micron thin sensors in future, a signal-to-noise of 40 is expected.Comment: Invited poster at the International Symposium on the Development of Detectors for Particle, AstroParticle and Synchrotron Radiation Experiments, Stanford CA (SNIC06) 6 pages, 12 eps figure

Metaproteome analysis reveals that syntrophy, competition, and phage-host interaction shape microbial communities in biogas plants

Background: In biogas plants, complex microbial communities produce methane and carbon dioxide by anaerobic digestion of biomass. For the characterization of the microbial functional networks, samples of 11 reactors were analyzed using a high-resolution metaproteomics pipeline. Results: Examined methanogenesis archaeal communities were either mixotrophic or strictly hydrogenotrophic in syntrophy with bacterial acetate oxidizers. Mapping of identified metaproteins with process steps described by the Anaerobic Digestion Model 1 confirmed its main assumptions and also proposed some extensions such as syntrophic acetate oxidation or fermentation of alcohols. Results indicate that the microbial communities were shaped by syntrophy as well as competition and phage-host interactions causing cell lysis. For the families Bacillaceae, Enterobacteriaceae, and Clostridiaceae, the number of phages exceeded up to 20-fold the number of host cells. Conclusion: Phage-induced cell lysis might slow down the conversion of substrates to biogas, though, it could support the growth of auxotrophic microbes by cycling of nutrients. © 2019 The Author(s)

Faktor Faktor Yang Berhubungan Dengan Perilaku Deteksi Dini Kanker Leher Rahim Metode Inspeksi Visual Asam Asetat Di Puskesmas Candiroto Kabupaten Temanggung

Perilaku deteksi dini kanker leher rahim dengan metode IVA adalah bentuk tindakan pemeriksaan deteksi dini kanker leher rahim dengan metode IVA. Kesadaran perempuan Indonesia untuk melakukan deteksi kanker leher rahim secara teratur masih rendah. Hal ini terlihat dari rendahnya cakupan deteksi dini kanker leher rahim dengan metode Inspeksi Visual Asam Asetat. Untuk tingkat Jawa Tengan hanya 1,08% dari jumlah wanita usia 30-50 tahun, Puskesmas Candiroto sekitar 5%. Tujuan penelitian ini adalah menganalisis faktor yang berhubungan dengan perilaku deteksi dini kanker leher rahim metode Inspeksi Visual Asam Asetat di Puskesmas Candiroto Kabupaten Temanggung. Penelitian ini merupakan penelitian dengan pendekatan cross sectional dengan analisis data uji chi-square dengan taraf signifikansi 95%. Subjek penelitian ini adalah wanita usia subur di wilayakh kerja Puskesmas Candiroto sejumlah 100 orang dengan menggunakan simple random sampling. Hasil uji chi-square ada hubungan antara keterpaparan informasi(p=0,1), dukungan suami (p=0,026), dan dukungan teman (p<0,0001) dengan perilaku deteksi dini kanker leher rahim metode IVA, serta tidak ada hubungan antara umur (p=0,07), pendidikan (p=0,17), pekerjaan (p=0,51), pengetahuan ((p=0,36), sikap (p=0,097), jarak (p=0,1), dukungan tenaga kesehatan (p=0,1) dengan perilaku deteksi dini kanker leher rahim metode IVA. dapat disimpulkan faktor yang berhubungan dengan perilaku deteksi dini kanker leher rahim metode Inspeksi Visual Asam Asetat di Puskesmas Candiroto Kabupaten Temanggung yaitu keterpaparan informasi, dukungan suami, dan dukungan teman.

News, intelligence and 'little lies' : rumours between the Cherokees and the British 1740-1785

Rumour and information are one of the most fundamental ways in which people engage with one another. Rumours can change the way that individuals and groups see each other and the actions that they take. Sociologists and anthropologists have long used rumour as a way to explore the experiences of their subjects. Historians of early America have, in recent years, begun to make use of rumour as a way of examining the, often hidden, world of interactions between American Indians and white Europeans. This thesis will expand upon this work by exploring the changing role of rumour within an intercultural relationship over several decades. This thesis will focus on rumour in the relationship between the Cherokee Nation and the colonists of the British Empire. It will explore the ways that rumour influenced these interactions and the impact of the rapidly changing backcountry environment of the latter eighteenth century, both on rumour and on the wider Cherokee- British relationship. This thesis will argue that rumour shifted in the course of the eighteenth century from being a diplomatic tool which could be used- either to create further panic and confusion or to calm and smooth over problems- to an uncontrollable force which would deepen and exacerbate the divisions between Cherokees and the British. Rumour played an important role in politics and society in the eighteenth century backcountry and its changing function offers a way to better understand the shifting currents of life in early America

Diffractive Photoproduction of Jets with a Direct Pomeron Coupling at HERA

We investigate in detail the effect of a direct pomeron coupling to quarks on the production of jets in $ep$ scattering with almost real photons. Jet production via a direct pomeron coupling is compared with the resolved--pomeron mechanism. We consider both direct and resolved photoproduction. Rapidity and transverse momentum distributions are calculated and compared with preliminary H1 and ZEUS data.Comment: 21 pages, Latex file, 7 figures (uuencoded) enclosed, Preprint DESY 94-140, KEK-TH-407 and KEK Preprint 94-7
