The Economics of Integrated Pest Control in Irrigated Rice

A Case Study from the Philippines

By: Hermann Waibel

As a result of the green revolution, the use of yield-increasing inputs such as fer tilizer and pesticides became a matter of course in irrigated rice farming in Southeast Asia. Pesticides were applied liberally, both as a guarantee against crop failure and as a means of fully utilizing the existing yield potential of the crops. However, since outbreaks of pests, such as the brown planthopper (BPH) or the tungro virus, continued to occur despite the application of chemicals, a change of approach began to take place. It is now being realized more and more in Southeast Asia that crop protection problems cannot be resolved solely by the application of chemicals. In the past several years, increasing efforts have there fore been made to introduce, as a first step, supervised crop protection, leading gradually to integrated pest management (Kranz, 1982). Although the crop protection problems naturally differ in the different devel oping countries in Southeast Asia, the economic situation prevailing in these countries can nevertheless be regarded as an important common determinant: pesticide imports use up scarce foreign currency and thus compete with other imports essential to development. For the individual rice farmer, the problem is basically the same: his cash funds are limited and he must carefully weigh whether to use them for purchas ing pesticides, fertilizer or certified seed. In view of this constraint, it is becom ing necessary to abandon the purely prophylactic, routine calendar spraying and instead, employ critically timed and need-based pesticide applications.

Before the Holocaust

Antisemitic Violence and the Reaction of German Elites and Institutions During the Nazi Takeover

By: Hermann Beck

As the Nazis staged their takeover in 1933, instances of antisemitic violence began to soar. While previous historical research assumed that this violence happened much later, Hermann Beck counteracts this, drawing on sources from twenty German archives, and focussing on this early violence, and on the reaction of German institutions and the elites who led them. Before the Holocaust examines the antisemitic violence experienced in this period - from boycotts, violent attacks, robbery, extortion, abductions, and humiliating 'pillory marches', to grievous bodily harm and murder - which has hitherto not been adequately recognized. Beck then analyses the reactions of those institutions that still had the capacity to protest against Nazi attacks and legislative measures - the Protestant Church, the Catholic Church, the bureaucracies, and Hitler's conservative coalition partner, the DNVP - and the mindset of the elites who led them, to determine their various responses to flagrant antisemitic abuses. Individual protests against violent attacks, the April boycott, and Nazi legislative measures were already hazardous in March and April 1933, but established institutions in the German State and society were still able to voice their concerns and raise objections. By doing so, they might have stopped or at least postponed a radicalization that eventually led to the pogrom of 1938 (Kristallnacht) and the Holocaust.

Cluster Analysis for Corpus Linguistics

By: Hermann Moisl

The standard scientific methodology in linguistics is empirical testing of falsifiable hypotheses. As such the process of hypothesis generation is central, and involves formulation of a research question about a domain of interest and statement of a hypothesis relative to it. In corpus linguistics the domain is text, and generation involves abstraction of data from text, data analysis, and formulation of a hypothesis based on inference from the results. Traditionally this process has been paper-based, but the advent of electronic text has increasingly rendered it obsolete both because the size of digital corpora is now at or beyond the limit of what can efficiently be used in the traditional way, and because the complexity of data abstracted from them can be impenetrable to understanding. Linguists are increasingly turning to mathematical and statistical computational methods for help, and cluster analysis is such a method. It is used across the sciences for hypothesis generation by identification of structure in data which are too large or complex, or both, to be interpretable by direct inspection. This book aims to show how cluster analysis can be used for hypothesis generation in corpus linguistics, thereby contributing to a quantitative empirical methodology for the discipline.
