Promoting Progress with Fair Use
The Intellectual Property (IP) Clause provides that Congress has the power to promote the Progress of Science and useful Arts by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries. In the realm of copyright, Congress and the courts have interpreted the clause as granting Congress a power not to promote progress but to establish limited IP monopolies. To return to an understanding of the IP power better grounded in the constitutional text, Congress and the courts should ensure that any IP enactment promote[s] ... Progress by considering whether it improves the quality or quantity of knowledge and aids the dissemination of knowledge, and whether it does so better than prior IP enactments. The courts can exercise the fair-use doctrine to aid in this re-constitutionalization of IP law by applying a fifth fair-use factor. This proposed fifth factor would balance the progress-promoting value of the alleged infringer\u27s use against the progress-promoting value of enforcing the copyright holder\u27s rights. Reviewing courts should presume that any alleged infringement is fair if it promotes progress better than the enforcement of the copyright
Codex Sinaiticus as a Window into Early Christian Worship
Codex Sinaiticus is the oldest and most complete New Testament in Greek known to exist. Its two colophons at the end of 2 Esdras and Esther indicate a possible connection with Pamphilusâ famous library at Caesarea in Palestine. Origen was head of a school for catechumens during his days in Alexandria in Egypt and later began a similar school in Caesarea. Pamphilus was Origenâs star pupil and later directed his school in Caesarea. These colophons may connect Sinaiticus with an ancient tradition of early Christian worship and instruction of new converts, possibly exhibited in particular scribal features. These scribal features are primarily located at âtwo-waysâ lists of âvirtue and viceâ in the New Testament, which were popular methods of instructing the essentials of the faith and are found throughout early Christian literature. These areas in the New Testament (and in the epistle of Barnabas) were emphasized through paragraph âlistsâ by the scribes of Sinaiticus. These âlistsâ were most likely recited by the ancient reader in a distinctive way for the audience. It is possible that the audience interacted with the reader as the text was recited.
This paper surveys the ancient practice of the public reading of scripture during Christian gatherings and the use of punctuation and lectional marking in manuscripts to aid readers in their task. A possible connection with earlier manuscripts is explored by a cursory examination of a similarity in formatting between Sinaiticus and P46, a second century copy of Paulâs epistles. When taken collectively, though sparse and fragmentary, the evidence suggests that Sinaiticus preserves an ancient practice of Christian instruction located in the unique paragraph âlistsâ of the âtwo-waysâ theme

NEW CHALLENGES IN INTERNATIONAL DAIRY TRADE
This paper was presented at the INTERNATIONAL TRADE IN LIVESTOCK PRODUCTS SYMPOSIUM in Auckland, New Zealand, January 18-19, 2001. The Symposium was sponsored by: the International Agricultural Trade Research Consortium, the Venture Trust, Massey University, New Zealand, and the Centre for Applied Economics and Policy Studies, Massey University. Dietary changes, especially in developing countries, are driving a massive increase in demand for livestock products. The objective of this symposium was to examine the consequences of this phenomenon, which some have even called a "revolution." How are dietary patterns changing, and can increased demands for livestock products be satisfied from domestic resources? If so, at what cost? What will be the flow-on impacts, for example, in terms of increased demands for feedgrains and the pressures for change within marketing systems? A supply-side response has been the continued development of large-scale, urban-based industrial livestock production systems that in many cases give rise to environmental concerns. If additional imports seem required, where will they originate and what about food security in the importing regions? How might market access conditions be re-negotiated to make increased imports achievable? Other important issues discussed involved food safety, animal health and welfare and the adoption of biotechnology, and their interactions with the negotiation of reforms to domestic and trade policies.

The b iosynthesis of histidine: imidazoleglycerol phosphate, imidazoleacteol phosphate, and histidinol phosphate
This is a report on the isolation and characterization of D-erythro-imidazoleglycerol phosphate (IGP), imidazoleacetol phosphate (IAP), and L-histidinol phosphate, which are accumulated in the mycelia of several of these mutants
Dementia, music and biometric gaming: Rising to the Dementia Challenge
In 2012, the U.K. government launched its Dementia Challenge, authorizing additional funding for dementia research and health care. The search for curative medicines is ongoing, but scientific research reveals evidence that music can play a positive role in general health, and in dementia and Alzheimerâs disease in particular. This article considers whether some of the challenges that dementia presents could be addressed through music therapy and proposes that biometric gaming might offer one means of channeling such associated health benefits to sufferers of dementia, even in the final stages of the disease
Photon Bubbles and the Vertical Structure of Accretion Disks
We consider the effects of "photon bubble" shock trains on the vertical
structure of radiation pressure-dominated accretion disks. These density
inhomogeneities are expected to develop spontaneously in radiation-dominated
accretion disks where magnetic pressure exceeds gas pressure, even in the
presence of magnetorotational instability. They increase the rate at which
radiation escapes from the disk, and may allow disks to exceed the Eddington
limit by a substantial factor. We first generalize the theory of photon bubbles
to include the effects of finite optical depths and radiation damping.
Modifications to the diffusion law at low optical depth tend to fill in the
low-density regions of photon bubbles, while radiation damping inhibits the
formation of photon bubbles at large radii, small accretion rates, and small
heights above the equatorial plane. Accretion disks dominated by photon bubble
transport may reach luminosities of 10 to >100 times the Eddington limit (L_E),
depending on the mass of the central object, while remaining geometrically
thin. However, photon bubble-dominated disks with alpha-viscosity are subject
to the same thermal and viscous instabilities that plague standard radiation
pressure-dominated disks, suggesting that they may be intrinsically unsteady.
Photon bubbles can lead to a "core-halo" vertical disk structure. In
super-Eddington disks the halo forms the base of a wind, which carries away
substantial energy and mass, but not enough to prevent the luminosity from
exceeding L_E. Photon bubble-dominated disks may have smaller color corrections
than standard accretion disks of the same luminosity. They remain viable
contenders for some ultraluminous X-ray sources and may play a role in the
rapid growth of supermassive black holes at high redshift.Comment: 38 pages, 2 figures, accepted for publication in The Astrophysical

A Shotgun Model for Gamma Ray Bursts
We propose that gamma ray bursts (GRBs) are produced by a shower of heavy
blobs running into circumstellar material at highly relativistic speeds. The
gamma ray emission is produced in the shocks these bullets drive into the
surrounding medium. The short term variability seen in GRBs is set by the
slowing-down time of the bullets while the overall duration of the burst is set
by the lifetime of the central engine. A requirement of this model is that the
ambient medium be dense, consistent with a strong stellar wind. The efficiency
of the burst can be relatively high.Comment: 4 pages, 2 figures, revised version accepted by ApJ Letter
Australian Organic Market Report 2010
This is the second report the Biological Farmers of Australia has commissioned to help industry bench mark the growth and health of its sectors. This report - another significant milestone in the two decade plus history of the rapidly developing Australian certified organic sector - builds the information base for industry to benchmark production and market value against past and current claims and estimates and will enable monitoring of future growth of the certified organic market in Australia and its farming and production base. In an industry characterised by operational diversity, this report allows for performance assessment by sector. The next publication in this series is planned in 2012 (biennial since the inaugural report in 2008) as a means of providing the wider industry with invaluable and realistic market information
