River Ouse: fisheries drought report 1996
The basis for undertaking this study was to examine factors and potential impacts affecting fish and fishing in relation to low flow drought conditions and what other impacts may arise as a result of further reduced flows resulting from abstraction. The study formed the basis of a three year project to concentrate on effects relating to potable water abstractions at Moor Monkton by YWS.
To fully evaluate the possible effects on fisheries the study set out to encompass fish population surveys from fry to adult stock, analysis of angler catch data, reports from anglers and river reports from Environment Agency Fisheries staff. In order to evaluate any effects of drought and abstraction a three year study was instigated to examine fish populations. Fish population surveys were conducted at six sites in which the triennial rolling programme formed the basis of site selection. Multi-method sampling techniques were carried out at several sites in order to evaluate capture efficiency.
Roach were prolific above the weir at Linton-on-Ouse, with gudgeon, perch and small bream also well represented. Roach dominated catches on the R.Ouse below Linton, with perch and bleak also relatively abundant.
Low flows were not thought to be directly correlated to successful recruitment of coarse fish, rather the associated high temperatures during drought conditions showing a strong positive effect with most species exhibiting growth rates above their long-term average.
At this stage in the study there are no clear indications that the drought has caused any deleterious effects to coarse fish populations or marked changes in species composition, with evidence of good recruitment by several species, indicating that the higher temperatures have generally been beneficial to recruitment. However, the indication that dace did not benefit as well as other coarse fish under these conditions may suggest some species are affected more than others. The successful strong recruitment of most coarse fish suggests that, in future,
fisheries will be supported by the 1995 year-class
A field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. 2nd draft 3rd August 1999
This manual has been produced by members of the national acoustics group (NAG) and represents the first in a series of outputs designed to promote co-ordination and consistency
in Agency hydroacoustic surveys. It is designed as a field guide for Agency staff operating the SIMRAD EY500 portable scientific echosounder. It should be simplistic enough for the newcomer to EY500 to be able to set up and run a mobile hydroacoustic survey with some knowledge of the supporting theory. It should act as guidance for standardisation of survey procedures providing a concise list of settings and recommendations that can be used as a quick reference guide in the field. This manual condenses 5 years of practical experience of surveying fish populations using Simrad hardware and software for surveying large rivers and still waters throughout England and Wales. This document should be used as a companion to the manufacturers instruction manual and not act as a substitute for it
Will Washington Provide Its Own Feedstocks for Biofuels?
The study finds that Washington State’s field corn, sugar beet and canola production could satisfy only a small percentage of the State’s annual gasoline or diesel consumption. Linear programming projections for 2008 showed a relatively close match between projected and actual production. Projections for 2009-2011 showed no increase in the State’s capacity to increase biofuel crop feedstocks. In comparison to crop feedstocks, Washington’s total annual lignocellulosic biomass is abundant. However, only a fraction of the biomass could be converted to biofuel due to high costs of collection and processing, competing markets for some biomass, and limitations in current technology.biofuels, biofuel feedstocks, canola, cellulosic inventories, grain corn, linear programming, Washington State
Assets return and risk and exchange rate trends : an ex post analysis
An earlier version of this paper has been presented at the Financial Services Symposium 2006 of the Financial
Services Institute, St. John’s University, 101 Murray Street, New York City, N.Y., September 8, 2006. We would
like to acknowledge the help provided by our research assistants, Matthew Horejs, Keith Brady, and Arati Gandhi.
Financial support from Henry George Research Funds (Robert Schalkenbach Foundation) is gratefully
acknowledged. The usual disclaimer applies.The objective of this analysis is to determine the movements (long-term trend) of the
exchange rate by looking at the rate of return and risk that financial assets (3-month T-bills)
have in four different economies, for four different investors. Risk averse speculators will try to
maximize their return and minimize risk by investing in different countries, and these capital
flows will affect the value of the four currencies (their exchange rates). The empirical results
show that before 2001 the return in the U.S. was high and the dollar was appreciated; after
2001, the same return became negative and the dollar was depreciated, but after 2004 the
returns have growing positively for the U.S. and relatively the same for the U.K.; the returns for
the Euro-zone and Japan are falling. So, the dollar is expected to appreciate, the pound might
experience a little appreciation and the euro will fall together with the yen. From this ex post
analysis, we can conclude that, by forecasting risk and return in countries’ assets, we can
determine the long-term trend of these currencies (exchange rates) in the future.peer-reviewe
A New Turn or More of the Same? A Structured Analysis of Recent Developments in Russian Foreign Policy Discourse
Russia and the European Union (EU) pursue active policies in their shared
neighbourhood. The official Russian foreign policy discourses that we analyse
here provide insights into the most important foreign policy ideas that Russia
seeks to promote. They show how Russia perceives its role in the region and
the world, as well as how it wants to develop its relations with neighbours.
Building on previous studies identifying the main discourses in Russian
foreign policy, this paper offers a new, comprehensive analysis of recent
Foreign Policy Concepts and the annual Presidential Addresses to the Federal
Assembly during President Vladimir Putin’s third term. The paper contributes
to our understanding of Russian foreign policy discourses and Russia’s stance
vis-a-vis the EU in the Eastern Partnership (EaP) region. Rather than focusing
on a single aspect of foreign policy (a common practice adopted by many
existing studies), it provides an analysis of all of them, thereby showing any
shift in emphasis on different aspects of foreign policy and regions over
time. Moreover, it takes a closer look at the content of the economic pitch
within the official Russian discourses to attract the countries in the
Commonwealth of Independent States (CIS). In this way, rather than focusing on
what Russia does not offer (the values and political system of Western
countries), it investigates whether the discourses presented contain a
potential positive offer for the countries in the region

Antecedents and performance consequences of international outsourcing
The outsourcing of intermediate products to international suppliers is believed to improve firm performance. We investigate this claim and test key dimensions of the decision to outsource internationally using survey data on 200 manufacturing firms located in the Netherlands. We find that most international outsourcing is intra-regional in nature. Furthermore international outsourcing is a consequence of a firm‟s ability to search and evaluate foreign suppliers, which is co-determined by its size, multinationality, and frequency of cross-border communications. Finally, no performance effects were observed for international or global outsourcing. We conclude international outsourcing is a balancing act between lower production costs abroad and lower transaction costs locally
The Elements of Russia’s Soft Power: Channels, Tools, and Actors Promoting Russian Influence in the Eastern Partnership Countries
Soft power can be exerted by a variety of actors using different channels and
tools. This paper focuses on actors and channels transmitting Russian messages
and discourses in the Eastern Partnership countries. It contributes to
enhancing our understanding of Russian influences in the region in two ways.
First, it maps the network of influential actors who have the potential to
transmit Russian messages and target various audiences. Second, it offers a
detailed analysis of the coverage of Russia (and the European Union (EU)) in
one important channel for dissemination of information about Russia and the
EU: popular TV stations in Belarus, Moldova, and Ukraine. The analysis shows
the presence of a wide variety of actors focusing on ‘compatriots’, religious
bonds, and Russian-language speakers in the region, which reflects the key
ideas of the ‘Russian World’ narrative. These actors promote Russia’s role as
a centre of gravity and aim to appeal to Russians, Slavs and Orthodox
Christians. This image of Russia, however, does not dominate the news
programmes in any of the three countries. In Moldova and Ukraine, Russia is
most often mentioned (negatively) in the context of security, while in Belarus
it is covered more often than the EU in economy-related news items. Moreover,
a large portion of the news about Russia and the EU has no positive or
negative tone or is presented in a balanced way. In general, apart from what
was conveyed by Russian TV channels, Russia does not have a more positive
image than the EU in the news programmes in the countries we monitored
