Schnelle Energiewende – bedroht durch Wutbürger und Umweltverbände? Protest, Beteiligung und politisches Risikopotenzialfür Großprojekte im Kraftwerk- und Netzausbau

Die deutsche Energiewende erfordert einen massiven Aus- und Neubau von Kraftwerken auf fossiler wie regenerativer Energiebasis sowie den Netzausbau. Die Beschleunigung der Planungs- und Genehmigungsverfahren hat für Regierung und Wirtschaft hohe Priorität. Dem stehen wachsende Beteiligungsansprüche von Bürgern und Interessengruppen gegenüber. Standortwahl und Umweltschutz führen oft zu Kontroversen und Protesten mit beträchtlichem politischem Risiko. Der Beitrag erörtert Widerstands- und Konfliktpotenzial im Umfeld von Energieprojekten und bewertet die Ressourcen und Strategien der Umweltverbände, deren Verhandlungsposition durch ein Urteil des Europäischen Gerichtshofs im Mai 2011 gestärkt wurde.Germany’s about-face in energy policy, the »Energiewende «, requires massive extension and new construction of fossil and renewable fuel power plants, as well as grid and transmission line extension. Acceleration of planning and permission processes is a high priority for government and industry. It stands in contrast to growing citizens’ and interest groups’ demands for participation. Siting and environmental concerns often lead to controversies and protest with considerable political risk. The article discusses resistance and conflict potential in energy project environments and evaluates resources and strategies of environmental groups, whose negotiating position has been strengthened by a May 2011 European Court of Justice decision

RFID als Feld für politische Debatten und Überzeugungsarbeit : Lobbying, politische Kommunikation und Themenmanagement

Politische Aspekte der RFID-Technologie werden im Bibliothekswesen überwiegend sektorspezifisch diskutiert. In der Vertretung ihrer Interessen gegenüber politischen Entscheidungsträgern stehen bibliothekstypische Finanzierungs- und Organisationsfragen im Vordergrund. Dabei kann jedoch die sektorübergreifende Kenntnis des Lobbyings von Industrie und Handel hilfreich sein. RFID ist zudem wegen der Datenschutzproblematik gesellschaftlich sehr umstritten. Auch wenn die Proteste abgeebbt sind, sind kritische Organisationen nach wie vor politisch aktiv und begleiten die Einführung der Technologie. Daraus ergibt sich die Notwendigkeit, Umfeld, Stakeholder und Risiken kontinuierlich zu beobachten und sich auf Konflikte bei Gesetzgebung und staatlicher Regulierung der RFID-Technik einzustellen

Legacy of European enterprise: teaching business history in the International Management curriculum

Unternehmensgeschichte kann ein wertvoller, sogar kritischer Beitrag in der Vermittlung des internationalen Managements sein – nicht nur an elitären Einrichtungen und im Master, sondern auch an Fachhochschulen und in Bachelor-Studiengängen. Besonders relevant ist sie für Studiengänge mit Fokus Europa. Studenten sollten eine Chance erhalten, die gemeinsame und zusammenhängende Vergangenheit europäischer Unternehmenstätigkeit zu entdecken. Der Artikel begründet die Integration ins Curriculum und diskutiert Fallauswahl und Lehrmethodik für Nichthistoriker. Eine exemplarische Auswahl von fünf Themen wird gezeigt: Ostindienkompanien, Finanzmarkt-Blasen, Telegrafie, der Suezkanal und die Entstehung von FluggesellschaftenBusiness history can be a valuable, even critical element in teaching international management – not only at elite institutions and at postgraduate level, but at universities of applied sciences and in undergraduate education, too. It is specifically relevant for programs with a focus on Europe. Students should be given a chance to discover common and connected pasts of European enterprise. The article offers a rationale for curriculum integration and discusses case selections and teaching methods for non-historians. Five exemplary themes are presented: East India companies, financial market bubbles, telegraphy, the Suez Canal, and the emergence of airlines

Shale Gas U-Turns in Bulgaria and Romania: The Turbulent Politics of Energy and Protest

After France, Bulgaria became the second EU country to enact an open-ended ban on hydraulic fracturing in early 2012. This government action was a radical departure from an initially friendly, even enthusiastic stance on unconventional gas development. It resulted in months of unprecedented, broad political pro-test from environmental groups and local communities. The conflict was interpreted as one involving old questions about Bulgaria’s orientation toward Russia or the West. In neighbouring Romania, Bulgaria’s U-turn on shale gas energized a protest movement which had been relatively weak. In a turbulent election-year context, political leaders scrambled to deal with highly symbolic issues. A new government introduced a moratorium but ended it less than a year later. Another U-turn in public policy happened. Romania parted from Bulgaria’s example and set out to move forward on shale gas, aiding foreign investors. Massive protests against the policy and the investors surged, en-circling the drilling operations. In both countries, public mistrust in institutions, environmental regulations and due process of law is a significant factor of political risk for energy companies

The diffusion-induced nova scenario. CK Vul and PB 8 as possible observational counterparts

We propose a scenario for the formation of DA white dwarfs with very thin helium buffers. For these stars we explore the possible occurrence of diffusion-induced CNO- flashes, during their early cooling stage. In order to obtain very thin helium buffers, we simulate the formation of low mass remnants through an AGB final/late thermal pulse (AFTP/LTP scenario). Then we calculate the consequent white dwarf cooling evolution by means of a consistent treatment of element diffusion and nuclear burning. Based on physically sounding white dwarf models, we find that the range of helium buffer masses for these diffusion-induced novas to occur is significantly smaller than that predicted by the only previous study of this scenario. As a matter of fact, we find that these flashes do occur only in some low-mass (M < 0.6M) and low metallicity (Z_ZAMS <0.001) remnants about 10^6 - 10^7 yr after departing from the AGB. For these objects, we expect the luminosity to increase by about 4 orders of magnitude in less than a decade. We also show that diffusion-induced novas should display a very typical eruption lightcurve, with an increase of about a few magnitudes per year before reaching a maximum of M_V ~ -5 to -6. Our simulations show that surface abundances after the outburst are characterized by logNH/NHe ~ -0.15...0.6 and N>C>O by mass fractions. Contrary to previous speculations we show that these events are not recurrent and do not change substantially the final H-content of the cool (DA) white dwarf.

The born again (VLTP) scenario revisited: The mass of the remnants and implications for V4334 Sgr

We present 1-D numerical simulations of the very late thermal pulse (VLTP) scenario for a wide range of remnant masses. We show that by taking into account the different possible remnant masses, the observed evolution of V4334 Sgr (a.k.a. Sakurai's Object) can be reproduced within the standard 1D-MLT stellar evolutionary models without the inclusion of any $ad-hoc$ reduced mixing efficiency. Our simulations hint at a consistent picture with present observations of V4334 Sgr. From energetics, and within the standard MLT approach, we show that low mass remnants \hbox{($M\lesssim0.6$\msun)} are expected to behave markedly different than higher mass remnants \hbox{($M\gtrsim0.6$\msun)} in the sense that the latter are not expected to expand significantly as a result of the violent H-burning that takes place during the VLTP. We also assess the discrepancy in the born again times obtained by different authors by comparing the energy that can be liberated by H-burning during the VLTP event.Comment: Submitted to MNRAS. In includes an appendix regarding the treatment of reduced convective motions within the Mixing Length Theor

On the robustness of H-deficient post-AGB tracks

We analyze the robustness of H--deficient post--AGB tracks regarding previous evolution of their progenitor stars and the constitutive physics of the remnants. Our motivation is a recent suggestion of Werner & Herwig (2006) that previous evolution should be important in shaping the final post--AGB track and the persisting discrepancy between asteroseismological and spectroscopical mass determinations. This work is thus complementary to our previous work (Miller Bertolami & Althaus 2006) and intends to shed some light on the uncertainty behind the evolutionary tracks presented there. We compute full evolutionary models for PG1159 stars taking into account different extramixing (overshooting) efficiencies and lifetimes on the TP-AGB during the progenitor evolution. We also assess the effect of possible differences in the opacities and equation of state by artificially changing them before the PG1159 stage. Also comparisons are made with the few H-deficient post--AGB tracks available in the literature. Contrary to our expectations, we found that previous evolution is not a main factor in shaping H--deficient post--AGB tracks. Interestingly enough, we find that only an increase of $\sim50$ in the intershell opacities at high effective temperatures may affect the tracks as to reconcile spectroscopic and asteroseismologic mass determinations. This forces us to conclude that our previous tracks (Miller Bertolami & Althaus 2006) are robust enough as to be used for spectroscopic mass determinations, unless opacities in the intershell region are substantially different. Our results, then, call for an analysis of possible systematics in the usually adopted asteroseismological mass determination methods.Comment: Accepted for publication in Astronomy and Astrophysc

Are planetary nebulae derived from multiple evolutionary scenarios?

Our understanding of planetary nebulae has been significantly enhanced as a result of several recent large surveys (Parker et al., these proceedings). These new discoveries suggest that the `PN phenomenon' is in fact more heterogeneous than previously envisaged. Even after the careful elimination of mimics from Galactic PN catalogues, there remains a surprising diversity in the population of PNe and especially their central stars. Indeed, several evolutionary scenarios are implicated in the formation of objects presently catalogued as PNe. We provide a summary of these evolutionary pathways and give examples of each. Eventually, a full census of local PNe can be used to confront both stellar evolution theory and population synthesis models.Comment: 4 pages, 1 figure.

How context can impact clinical trials : a multi-country qualitative case study comparison of diagnostic biomarker test interventions

Background Context matters for the successful implementation of medical interventions, but its role remains surprisingly understudied. Against the backdrop of antimicrobial resistance, a global health priority, we investigated the introduction of a rapid diagnostic biomarker test (C-reactive protein, or CRP) to guide antibiotic prescriptions in outpatient settings and asked, “Which factors account for cross-country variations in the effectiveness of CRP biomarker test interventions?” Methods We conducted a cross-case comparison of CRP point-of-care test trials across Yangon (Myanmar), Chiang Rai (Thailand), and Hanoi (Vietnam). Cross-sectional qualitative data were originally collected as part of each clinical trial to broaden their evidence base and help explain their respective results. We synthesised these data and developed a large qualitative data set comprising 130 interview and focus group participants (healthcare workers and patients) and nearly one million words worth of transcripts and interview notes. Inductive thematic analysis was used to identify contextual factors and compare them across the three case studies. As clinical trial outcomes, we considered patients’ and healthcare workers’ adherence to the biomarker test results, and patient exclusion to gauge the potential “impact” of CRP point-of-care testing on the population level. Results We identified three principal domains of contextual influences on intervention effectiveness. First, perceived risks from infectious diseases influenced the adherence of the clinical users (nurses, doctors). Second, the health system context related to all three intervention outcomes (via the health policy and antibiotic policy environment, and via health system structures and the ensuing utilisation patterns). Third, the demand-side context influenced the patient adherence to CRP point-of-care tests and exclusion from the intervention through variations in local healthcare-seeking behaviours, popular conceptions of illness and medicine, and the resulting utilisation of the health system. Conclusions Our study underscored the importance of contextual variation for the interpretation of clinical trial findings. Further research should investigate the range and magnitude of contextual effects on trial outcomes through meta-analyses of large sets of clinical trials. For this to be possible, clinical trials should collect qualitative and quantitative contextual information for instance on their disease, health system, and demand-side environment.
