Members of parliament are key actors for the implementation of energy transitions, such as phasing out nuclear power. Before legislators can cast their maybe decisive vote in parliament, they need to run for office and actively strive for election. This paper assesses what political candidates oppose renewable energy transitions and questions whether the energy issue matters in national elections, and thus has consequences for the implementation of new sustainable energy sources. We analyze these questions by first describing the specific characteristics of political candidates. The paper then evaluates the relevance of the energy issue for electoral success in three national elections in Switzerland (2007, 2012, and 2015). Based on candidate data from the voting advice application smartvote.ch, we find that female candidates support ETs more than men do; that especially the French‐speaking part of the country is more in favor of a nuclear phase‐out, and that younger candidates are also more open toward restructuring the energy system than older candidates are. Our models further show that the energy issue does not matter in elections, independently from its salience in the respective election campaigns. Candidates are thus relatively free to choose their position on the issue and do not have to fear consequences at the ballot. However, candidates of center parties, in contrast to the pole parties, are sensitive to the energy issue and reflect public mood in their positions. 相似文献

A simple, quick, selective, sensitive, and effective field-friendly method capable of being used by nonexperts has been developed for detecting mitragynine in Mitragyna speciosa (kratom) using surface-enhanced Raman spectroscopy (SERS). Over 100 samples and blanks (known to be either positive or negative for the presence of mitragynine) were examined in duplicate using five identical handheld Raman spectrometers, which provided a data set of over 1,000 examinations. Based on the results of these analyses, the method yielded a true-positive rate of 99.3%, a true-negative rate of 97.9%, a false-positive rate of 2.1%, and a false-negative rate of 0.7%. The average minimum detectable concentration (Cm) of mitragynine that reproducibly yielded a match for one of the library spectra on all five instruments was determined to be 342 ng/mL (ppb). This Cm value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the Cm value achieved was well below typical mitragynine concentrations in kratom (1.3–2.3%). The method is ideal (i) for prioritizing samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify mitragynine and (ii) for field use at international mail facility (IMF) satellite laboratories to help interdict kratom and prevent this dangerous product from reaching the U.S. supply chain. 相似文献

This article presents a conceptual framework for analysing the governance of natural resource use, as governance is often the primary issue when natural resources are overexploited and degraded. It addresses both spontaneous and active governance, including institutional change induced by development co‐operation. Drawing on existing frameworks of institutional analysis, fundamental modifications are presented to adapt the concept to the context of international co‐operation, and to include dynamic aspects of institutional change as well as multiple actor interactions. Tested in several case studies, the framework was found suitable and relevant for use in project planning and evaluation, as well as for comparing governance issues across cases in a conceptually rigorous way.

The Targeted Jobs Tax Credit (TJTC) is a representative redistributive incentive. Initially, proponents saw TJTC as an elegant program, efficiently promoting labor market behavior that would solve the employment problems of many disadvantaged job seekers. However, interest groups distorted the credit into a windfall for businesses that hire large numbers of low wage workers. The policy theories incorporated into TJTC, which emphasized continual program reform and minimized program management by public administrators, provided a setting conducive to interest group distortion. Because few representatives of the disadvantaged participated in the oversight process, special interests undermined TJTC being reformed through empirical evaluation. This experience indicates that without major changes in the policy process, narrowly targeted rzdistributive policies should be avoided. 相似文献

Forensic analysis of glass samples was performed in different laboratories within the NITE-CRIME (Natural Isotopes and Trace Elements in Criminalistics and Environmental Forensics) European Network, using a variety of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) systems. The main objective of the interlaboratory tests was to cross-validate the different combinations of laser ablation systems with different ICP-MS instruments. A first study using widely available samples, such as the NIST SRM 610 and NIST SRM 612 reference glasses, led to deviations in the determined concentrations for trace elements amongst the laboratories up to 60%. Extensive discussion among the laboratories and the production of new glass reference standards (FGS 1 and FGS 2) established an improved analytical protocol, which was tested on a well-characterized float glass sample (FG 10-1 from the BKA Wiesbaden collection). Subsequently, interlaboratory tests produced improved results for nearly all elements with a deviation of < 10%, demonstrating that LA-ICP-MS can deliver absolute quantitative measurements on major, minor and trace elements in float glass samples for forensic and other purposes. 相似文献

Das Umweltrecht nimmt in vielfältigen Formen und Verfahren Einfluss auf die Regionalplanung als (Haupt-)Instrument nachhaltiger Regionalentwicklung. Der Beitrag beleuchtet dies unter rechtlichen Aspekten und bezieht hierzu Stellung. Die Kritik richtet sich u. a. auf die Heterogenität umweltrechtlicher Agenden und die eingeschränkte Sanktionierung von Verstößen gegen Vorgaben des Umweltrechts.
