DOC-trail: 20 years of organic and conventional farming affect soil microbial properties

In a long-term field trial (DOC; = bio-Dynamic, bio-Organic, Conventional) at Therwil, Switzerland, agricultural production systems have been compared since 1978. The production systems differ mainly in the amount and form of fertiliser and plant protection strategy. Crop rotation and soil tillage were the same. In the most prominent systems soil microbial properties were investigated for the first time after two crop rotations in 1990. In 1998, after 3 crop rotations, soil microbial properties were investigated in all field plots. Conclusions Agricultural systems exert distinct effects on chemical and microbiological soil properties, prominently the bio-dynamic system with the application of composted manure. Part of the influence on microbiological parameters appears to be indirect through chemical properties. The differentiation of the systems remained stable for the last eight years of the trial

Electoral Acceleration: The Effect of Minority Population on Minority Voter Turnout

Political outcomes are well understood to depend on the spatial distribution of citizen preferences. In this paper, we document that the same holds for the individual decision to be politically active. Using both cross-sectional and longitudinal evidence on turnout, we show that citizens are more likely to vote if they live in a jurisdiction with a larger number of persons sharing similar political preferences. As a result, changes in the identity of a district's median citizen lead to even larger changes in the identity of its median voter, a phenomenon we term electoral acceleration. We present evidence that electoral acceleration is in part due to the structure of media markets. Candidates find it easier to direct campaign efforts at larger groups because many existing media outlets cater to this audience.

Political Relationships, Global Financing and Corporate Transparency

This study examines the financing choices of firms operating in a weak institutional environment. We argue that in relationship-based systems, global financing and strong political connections are alternative means to create firm value. Well-connected firms might be less inclined to access global capital markets because (state-owned) domestic banks provide capital at low cost. Moreover, the expanded disclosures and additional scrutiny that come with issuing foreign securities might be at odds with close political ties at home because these ties can best be exploited when little is disclosed about the firm. Using data from Indonesia, we provide strong support for the hypothesis that global financing and political connections are substitutes: Firms with close political ties to former President Soeharto are significantly less likely than nonconnected firms to have publicly traded foreign securities. To study performance effects, we examine how returns during the Asian financial crisis differ between firms with and without foreign securities. Consistent with prior work, we find that firms with foreign securities exhibit higher returns during the crisis. However, our data indicate that politically well-connected firms also received considerable support during this period. These results suggest that previous estimates of cross-listing benefits are considerably biased if domestic opportunities such as political connections are ignored.

Media Markets and Localism: Does Local News en Español Boost Hispanic Voter Turnout?

Since the dawn of broadcasting, and especially in the past decade, Americans have turned their attention from local to more distant sources of news and entertainment. While the integration of media markets will raise the private welfare of many consumers, a globalized information and entertainment industry can undermine civic engagement, transforming locally engaged citizens into viewers consuming programming from distant sources. In response to such concerns, many regulatory agencies, including the Federal Communication Commission in the United States, curtail the integration of media markets to promote %u201Clocalism.%u201D Determining the right balance between the private benefits of integrated markets and the public value of civic engagement requires evidence on the size of the positive spillovers from local media. In this paper, we exploit the rapid growth of Hispanic communities in the United States to test whether the presence of local television news affects local civic behavior. We find that Hispanic voter turnout increased by 5 to 10 percentage points, relative to non-Hispanic voter turnout, in markets where local Spanish-language television news became available. Thus, the tradeoff between integrated media markets and civic engagement is real, and our results provide a basis for the continued pursuit of regulatory policies that promote localism.

Analysis of shot noise suppression in mesoscopic cavities in a magnetic field

We present a numerical investigation of shot noise suppression in mesoscopic cavities and an intuitive semiclassical explanation of the behavior observed in the presence of an orthogonal magnetic field. In particular, we conclude that the decrease of shot noise for increasing magnetic field is the result of the interplay between the diameter of classical cyclotron orbits and the width of the apertures defining the cavity. Good agreement with published experimental results is obtained, without the need of introducing fitting parameters.Comment: 5 pages, 3 figures, contents changed (final version

An alternative academic creative writing pedagogy? The research and development of theorised teaching principles and processes for a BA honours degree in creative writing and an MA degree in the teaching of creative writing

A thesis submitted to the Faculty of Arts, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2014This study examines the available literature on creative writing as a discipline in higher education institutions and analyses a range of aspects relevant to its teaching, including its international and local origins; its development as a high-demand product of the higher education industry; its resultant position, form and role as an academic discipline; whether it can be taught and how it is influenced by its institutional location. This study then identifies and examines certain neglected components of the teaching and learning of creative writing, including the conceptions and expectations of student writers, the significance of creativity in teaching students to write creatively, and the role of the reader as textual participant. Having identified a paucity of formally developed creative writing principles and processes, this study undertakes to establish a theorised pedagogic platform by means of the research and analysis of pertinent aspects of creative writing and its teaching, including a broad selection of creative writing handbooks as a representation of formal, recorded creative writing pedagogy; creative writing theories and findings relevant to the pursuance of creativity in writing and relevant to its teaching environment; the significance of the reader and her textual criteria as co-creator and ultimate judge of textual quality; and the written responses of undergraduate students to the principles, methods, exercises and assignments experienced during their participation in a research based, four-year, creative writing workshop programme. The findings of the theoretical and experiential evaluations are merged, analysed and consolidated in the study’s conclusions. These conclusions form a theorised, alternative academic pedagogic creative writing platform consisting of the teaching of creative writing as an experiential process, aimed at students as writers, focusing on creativity, the reader and on writing as a process and a craft, in an Arts-based, authoritatively neutral and creativity conducive environment. Derived from this alternative pedagogic platform, the study develops the framework of the syllabi of a BA Honours Degree in Creative Writing and an MA Degree in the Teaching of Creative Writing

Sprachgebrauch und Spracheinstellungen in der Deutschschweiz. Pfarrpersonen als sprachbewusste Sprecherinnen und Sprecher im Fokus

The relation between Swiss German dialects and Standard German has been subject to public and scholarly debates for over 100 years. Among the most frequently discussed points are the appropriateness of spoken Standard German in different contexts and the attitudes of Swiss people towards the two varieties. This paper summarises the results of a completed research project (Oberholzer in Vorb.), which surveyed language use and language attitudes in Swit-zerland for a specific group of speakers: pastors and priests working in German-speaking Switzerland. The paper shows how pastors and priests make use of the diglossic situation and the possibility to code-switch in Sunday services. The use of Standard German emerges as an important communicative resource in German-speaking Switzerland. In addition, real language use and intended language use match to a high degree; this shows the degree of language awareness of this particular group in a diglossic situation. Furthermore, a relatively new approach – the assumption that several mental models of High German coexist – helps to show differentiated language attitudes and to contradict some of the most common stereotypes regarding Standard German in German-speaking Switzerland. The attitudes towards Standard German in this study are significantly more positive than those observed in previous studies
