Corn Producer Practices and Insect Resistance Management Requirements
We document the degree to which corn producers in South Dakota follow Insect Resistance Management requirements administered by the Environmental Protection Agency. Our findings are based a survey held among a sample of 317 corn producers in South Dakota in July of 2004. Detailed results are forthcoming.Farm Management,

Review and Analysis of International and Budgetary Considerations for the 2007 U.S. Farm Bill
We assess the extent to which national budget considerations, international trade negotiations, and domestic political deliberations affect the potential development of an omnibus farm bill, which may be signed into law in 2008. With no successful conclusion of the Doha Development Round of trade negotiations in sight, U.S. legislators appear unable to make politically unpopular decisions on domestic farm policy reform. However, the absence of an international trade agreement does not reduce the need for the U.S. to comply with previous agreements.farm bill, budget deficit, international trade agreements, agricultural policy
Market impact costs of institutional equity trades
This paper is the first to analyze market impact and execution costs of equity trading by a pension fund. We find that, on average, these costs are nonnegligible. Average market impact costs equal 20 basis points for buys and 30 basis points for sells; average execution costs equal 27 basis points and 38 basis points, respectively. Furthermore, we show that relative trade size and market capitalization, commonly found to play an important role, have only limited influence on the market impact of a trade. The most important determinants of the price effect are momentum, stock price volatility, investment style, trade type (agency, single, or principal), and trading venue
Stepwise evolution of the Sec machinery in Proteobacteria
The Sec machinery facilitates the translocation of proteins across and into biological membranes. In several of the Proteobacteria, this machinery contains accessory features that are not present in any other bacterial division. The genomic distribution of these features in the context of bacterial phylogeny suggests that the Sec machinery has evolved in discrete steps. The canonical Sec machinery was initially supplemented with SecB; subsequently, SecE was extended with two transmembrane segments and, finally, SecM was introduced. The Sec machinery of Escherichia coli and other Enterobacteriales represents the end product of this stepwise evolution.</p
Cheap versus expensive trades: Assessing the determinants of market impact costs
This paper assesses the determinants of market impact costs of institutional equity trades, using unique data from the world's second largest pension fund. We allow the impact of trade characteristics and market conditions on trading costs to depend on the level of trading costs itself and establish significant differences in the responses of cheaper and more expensive trades. We explain the distinct responses from differences in information content and demand for liquidity between trades with high and low trading costs. Finally, to illustrate the practical relevance of the approach, we use our method to forecast future trading costs
Designing a flexible support system in dialogue with students to meet their needs
A more stringent financial climate, alongside technological and lifestyle changes, have diversified student needs and promoted the use of inclusive learning and support strategies. This paper reports on the development and evaluation of academic skills centres at an English Higher Education Institution and considers ways in which the service is able to benefit users and providers, it goes on to argue that, by fostering a dialogue with students and using a range of delivery models, the provision has been made flexible, diversified and student centred and thereby addresses issues of current significance within the institution and sector more broadly
Pilot Sportplein Groningen: zelfregulatie in het VMBO
In het kader van kwaliteitsverbetering van bewegingsonderwijs heeft er in het voorjaar van 2014 een pilot plaatsgevonden waarin in een tweetal lessenreeksen van drie lessen (floorball en judo) meer aandacht is geweest voor zelfregulatie. Zelfregulatie is de mate waarin een individu in staat is om zelfstandig, doelbewust en efficiënt te leren door het gebruik van verschillende vaardigheden. Uit onderzoek onder sporttalenten is gebleken dat zelfregulatie een belangrijke rol speelt omdat sporttalenten in korte tijd veel moeten leren om de top te bereiken. Ook in de schoolcontext is zelfregulatie een belangrijke bepaler voor succes. Doelstelling van de pilot is zelfregulatie een plek te geven binnen de lessen judo en floorball, gegeven op het VMBO. Met het stimuleren van zelfregulatie bij de doelgroep VMBO leerlingen is nog weinig ervaring en de pilot dient dan ook ter verkenning. Om te leren van de ervaringen met de pilot, is hieraan een exploratief onderzoek gekoppeld, met het volgende doel: Inzicht geven in hoeverre zelfregulatie een plek krijgt binnen de pilotlessen floorball en judo en evalueren hoe leerlingen en docenten de lessen ervaren. Het onderzoek is uitgevoerd in opdracht van Sportplein Groninge
