Organic farm incomes in England and Wales 2006/07 (OF 0373)
In the report, we present results of research on the financial performance of organic farms in 2006/07 carried out for the Department for Environment, Food and Rural Affairs (Defra). The main aim of this work is to assess the financial performance of organic farms differentiated by farm type, in order to inform Defra policy-making with respect to economics of organic farming, and to provide a basis for assessments by farmers, advisers and other interested parties of the farm-level implications of conversion to and continued organic farming. This research builds on previous work on the economics of organic
farming carried out at Aberystwyth University (Projects OF0190, covering 1995/96 to 1998/99 and OF0189, covering 1999/00 to 2004/05).
In this report, financial data are shown for the 2005/06 and 2006/07 financial years, including between year comparisons and comparisons with similar conventional farms. For this report only, it has not been possible to produce identical samples for all farm types due to the change in data collection approach between 2005/06 and 2006/07. Identical sample comparisons have only been possible for lowland dairy and lowland and LFA cattle and
sheep systems. The identical farm samples comprise farms that are present in both the 2005/06 and 2006/07 datasets. The total number of organic farms for 2006/07, also
referred to as the full farm sample data, is shown alongside the identical datasets. In the other cases, data for the full samples in 2005/06 and 2006/07 are presented, but comparisons should be treated with caution due to changes in sample composition.
Summarised and detailed financial input, output, income, returns to labour and capital, liabilities and assets and some physical performance measures are presented based on
current Farm Business Survey (FBS) data collection and collation guidelines. The full samples of organic farms per robust farm type are sufficiently large to give some
reasonable level of confidence in the data although it should be noted that the organic farm samples are not statistically representative of their type. However, the results can be seen as a reasonable indication of farm income levels for comparable organic and conventional
farms. Smaller farm samples should be treated more cautiously as there is a possibility for outliers (especially larger farms) to have a significant influence on the average results.
An additional element of this work is the inclusion of comparable conventional farm data (obtained from the main FBS sample) for the farm types shown. Each organic farm within this study was matched with an appropriate cluster of conventional farms based on the resource endowment indicators for individual organic farms. The indicators included farm type, FBS region, Less Favoured Area (LFA) status, utilisable agricultural area (UAA), milk quota held (where applicable) and farm business size. The cluster farm data were averaged for each farm type to derive the comparable conventional farm (CCF) data based on the organic farms from the identical and full farm samples.
The identical samples of organic farms showed a much higher level of net farm incomes for lowland dairy and lowland cattle and sheep in 2006/07 than in 2005/06, with LFA cattle and sheep showing a small decrease over the period. Overall, organic net farm incomes exceeded conventional in all sectors, with most sectors showing an organic NFI
twice that of the comparative conventional NFI. Increased organic prices and only small cost increases have led to substantial increases in organic NFI, especially in the livestock sectors
Breaking through the glioblastoma micro-environment via extracellular vesicles
Glioblastoma (GBM) is the most common and most aggressive brain tumour. Prognosis remains poor, despite the combined treatment of radio- and chemotherapy following surgical removal. GBM cells coexist with normal non-neoplastic cells, including endothelial cells, astrocytes and immune cells, constituting a complex and dynamic tumour micro-environment (TME). Extracellular vesicles (EVs) provide a critical means of bidirectional inter-cellular communication in the TME. Through delivery of a diverse range of genomic, lipidomic and proteomic cargo to neighbouring and distant cells, EVs can alter the phenotype and function of the recipient cell. As such, EVs have demonstrated their role in promoting angiogenesis, immune suppression, invasion, migration, drug resistance and GBM recurrence. Moreover, EVs can reflect the phenotype of the cells within the TME. Thus, in conjunction with their accessibility in biofluids, they can potentially serve as a biomarker reservoir for patient prognosis, diagnosis and predictive therapeutic response as well as treatment follow-up. Furthermore, together with the ability of EVs to cross the bloodâbrain barrier undeterred and through the exploitation of their cargo, EVs may provide an effective mean of drug delivery to the target site. Unveiling the mechanisms by which EVs within the GBM TME are secreted and target recipient cells may offer an indispensable understanding of GBM that holds the potential to provide a better prognosis and overall quality of life for GBM patients
Endogenous Games and Mechanisms: Side Payments Among Players
We characterize the outcomes of games when players may make binding offers of strategy contingent side payments before the game is played. This does not always lead to efficient outcomes, despite complete information and costless contracting. The characterizations are illustrated in a series of examples, including voluntary contribution public good games, Cournot and Bertrand oligopoly, principal-agent problems, and commons games, among others.game theory, mechanism design, contracts, side payments, endogenous games, public goods
Molecular clouds and clumps in the Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey
The Boston University-Five College Radio Astronomy Observatory (BU-FCRAO)
Galactic Ring Survey (GRS) of 13 CO (1-0) emission covers Galactic longitudes
18 deg < l < 55.7 deg and Galactic latitudes |b| <= 1 deg. Using the SEQUOIA
array on the FCRAO 14m telescope, the GRS fully sampled the 13 CO Galactic
emission (46 arcsec angular resolution on a 22 arcsec grid) and achieved a
spectral resolution of 0.21 km/s. Because the GRS uses 13 CO, an optically thin
tracer, rather than 12 CO, an optically thick tracer, the GRS allows a much
better determination of column density and also a cleaner separation of
velocity components along a line of sight. With this homogeneous, fully-sampled
survey of 13 CO, emission, we have identified 829 molecular clouds and 6124
clumps throughout the inner Galaxy using the CLUMPFIND algorithm. Here we
present details of the catalog and a preliminary analysis of the properties of
the molecular clouds and their clumps. Moreover, we compare clouds inside and
outside of the 5 kpc ring and find that clouds within the ring typically have
warmer temperatures, higher column densities, larger areas, and more clumps
compared to clouds located outside the ring. This is expected if these clouds
are actively forming stars. This catalog provides a useful tool for the study
of molecular clouds and their embedded young stellar objects.Comment: 29 pages. ApJ in pres
Institutionalising Design Education and Design Promotion in Australia: From early British influences to wider international engagement
Industrial design has grown in Australia from a series of
unnamed activities clustered about an emerging 19th
century manufacturing industry into a recognised
profession. This transformation largely occurred because of
the emergence of specific design education and the
support offered by professional design associations.
Designers working for the early Australian manufacturing
industry were given technical education in the areas of
engineering, draughtsmanship and foundry work from
1827 onwards in Mechanicsâ Institutes. It was from this
technical base that the early âdesignersâ working for
industry sprang. Technical Schools, Schools of Art and
Schools of Mines and Industries all offered training for the
designer before industrial design was finally offered as a
course of study at tertiary level after WWII. Concurrent with
this, professional associations arose to support the
emerging industrial design industry in Australia. Nineteenthcentury
precursors to âmodernâ design education -
Mechanicsâ Institutes, Technical Schools, Schools of Art,
Schools of Mines and Industries, Junior Technical Schools,
Apprenticeships and Secondary School design education -
will be surveyed. As with many countries, WWII was a
catalysing time for Australian industry as the country geared
up production. At the conclusion of hostilities, Australiaâs
first specific Industrial Design course at tertiary level was
born.
The purpose of this paper is to show how industrial design
activity in Australia has become a profession. An early
British lead in both design education and professional
design associations was soon broadened to include other
international models, as the Australian design industry and
Australian society generally, looked to countries other than
the âmother landâ. This paper argues industrial design
activity was expanded in every way by the experience of
mass-production of goods for the war effort, by new
immigrants arriving in this country who often had skills
lacking locally, and by the new opportunities offered by the
post-war reconstruction programmes. Industrial design was
formalised as a profession by industrial design education at
tertiary level and the assistance offered t
Battlegrounds of environmental change
The Thames catchment encompasses one of Europeâs largest cities, the UKâs principal
aquifer, an extensive zone of coastal interaction and much else. It presents a unique
conjunction of geological, hydrogeological, environmental and socio-economic factors that are
intrinsically linked by the effects of environmental change and the pressures of developmen
Communication and equilibrium in discontinuous games of incomplete information
This paper offers a new approach to the study of economic problems usually modeled as games of incomplete information with discontinuous payoffs. Typically, the discontinuities arise from indeterminacies (ties) in the underlying problem. The point of view taken here is that the tie-breaking rules that resolve these indeterminacies should be viewed as part of the solution rather than part of the description of the model. A solution is therefore a tie-breaking rule together with strategies satisfying the usual best-response criterion. When information is incomplete, solutions need not exist; that is, there may be no tie-breaking rule that is compatible with the existence of strategy profiles satisfying the usual best-response criteria. It is shown that the introduction of incentive compatible communication (cheap talk) restores existence
Augustana Seniors Fall 1884: William Mering Reck
William Mering Reck was a senior at Augustana College, Rock Island, Illinois, in the fall of 1884. His name appears in the college catalog of 1884 â 1885, along with his birthplace, the year of his birth, and a few other facts. From this start, we researched the genealogy and family history of Reck. This paper contains a short biography of Reck, a report on his ancestors, a report on his descendants, and some open questions for further research
The complex adoption pathways of digital technology in Australian livestock supply chains systems
This paper reviews early experiences, expectations and obstacles concerning the adoption of digital technologies in Australian livestock systems. Using three case studies of publicly-available information on Australiaâs red meat industry, we identify the process of digitally enhanced value creation according to four themes: (1) supply chain operability; (2) product quality; (3) animal welfare; and (4) innovation and learning. We find reasons for both optimism and pessimism concerning the adoption of digital agriculture. While digital technology is being offered by various stakeholders to support collaboration within supply chains, it is also being met with scepticism amongst some producers who are not actively engaging with a digital transformation. We identify that the âtechnology fallacyâ, which proposes that organisations, people, learning and processes are as important to digital transformation as the technology itself; but while digital technologies enable change, it is the people who determine how quickly it can occur. We argue that â since quality appears to be the major basis on which Australian red meat producers will compete in global markets â the broad adoption of digital technology will prove increasingly essential to future growth and sustainability of this supply chain
