Herring, Sardines, and Foreign Affairs: Determination of Optimum Yield Under the Fishery Conservation and Management Act of 1976—Maine v. Kreps, 563 F.2d 1043 (1st Cir.), remanded, No. 77-45-SD (S.D. Me. Aug. 26, 1977), aff\u27d, 563 F.2d 1052 (1st Cir. 1977)
This note will analyze the major issue of Maine v. Kreps, whether Secretary Kreps fulfilled the FCMA\u27s requirements in her determination of optimum yield. This issue is discussed in two parts. First, the criteria expressed in the preliminary management plan are analyzed in light of the relevant provisions of the FCMA. Second, the inclusion of foreign policy considerations in the optimum yield calculations (a factor not discussed in the preliminary management plan) is analyzed by (1) inferring from the Maine opinion the proper use of foreign policy in management decisions, and (2) suggesting criteria which may affect the role of foreign policy in the development of future management plans. This note concludes that the need for rebuilding a fish stock and the capacity and incentive of domestic fishermen to exploit that fish stock are appropriate considerations in determining optimum yield. These considerations should, however, be treated more comprehensively than they are in Secretary Kreps\u27 preliminary management plan. The FCMA also requires an analysis of the effects a fishing quota might have on other interrelated fish stocks whether or not those stocks are under exclusive U.S. control. The effect of fishing quotas on U.S. foreign relations is an appropriate secondary consideration in establishing optimum yield, but the possible decrease in efficiency of domestic fishermen caused by increased foreign fishing should be considered as well
Measuring School Capacity, Maximizing School Improvement
Given the nearly ubiquitous use of the term capacity in education policy discourse, this policy brief offers a common framework for analyzing capacity that educators, policymakers, and researchers alike can apply and understand with consistency. Drawing data from a larger three-year CPRE study of school responses to accountability in Pennsylvania, the authors\u27 goal is not to provide an easy, new, one-sentence definition, but rather to create a shared language that can be applied to research and improvement efforts in schools. To accomplish this, the authors break capacity down into component parts, explaining how each one builds off the next and contributes to theoverall concept
Towards Communication-Efficient Quantum Oblivious Key Distribution
Oblivious Transfer, a fundamental problem in the field of secure multi-party
computation is defined as follows: A database DB of N bits held by Bob is
queried by a user Alice who is interested in the bit DB_b in such a way that
(1) Alice learns DB_b and only DB_b and (2) Bob does not learn anything about
Alice's choice b. While solutions to this problem in the classical domain rely
largely on unproven computational complexity theoretic assumptions, it is also
known that perfect solutions that guarantee both database and user privacy are
impossible in the quantum domain. Jakobi et al. [Phys. Rev. A, 83(2), 022301,
Feb 2011] proposed a protocol for Oblivious Transfer using well known QKD
techniques to establish an Oblivious Key to solve this problem. Their solution
provided a good degree of database and user privacy (using physical principles
like impossibility of perfectly distinguishing non-orthogonal quantum states
and the impossibility of superluminal communication) while being loss-resistant
and implementable with commercial QKD devices (due to the use of SARG04).
However, their Quantum Oblivious Key Distribution (QOKD) protocol requires a
communication complexity of O(N log N). Since modern databases can be extremely
large, it is important to reduce this communication as much as possible. In
this paper, we first suggest a modification of their protocol wherein the
number of qubits that need to be exchanged is reduced to O(N). A subsequent
generalization reduces the quantum communication complexity even further in
such a way that only a few hundred qubits are needed to be transferred even for
very large databases.Comment: 7 page
Learning From NCLB: School Responses to Accountability Pressure and Student Subgroup Performance
Much has been written in the last decade about the spotlight that the No Child Left Behind Act (NCLB) shines on schoolperformance. Proponents and opponents alike are quick to discuss the law’s rigid definitions of school performance— exemplified by the classification of schools as making Adequate Yearly Progress (AYP) or not making AYP based largely on annual tests in reading and mathematics, disaggregating school performance by student subgroups, and requiring that all schools reach 100% proficiency. Yet for all its rigidity, the law has offered schools little guidance on how to make use of the performance data that the new systems provide or how to design improvement efforts. As policymakers discuss ways to change NCLB or design new federal education policies targeted at improving academic achievement, we present new research findings that can help to inform those discussions.
In this CPRE Policy Brief, we examine the extent to which the assumptions in the law manifest themselves in the actions that school leaders take. This brief asks and answers the question: How do school leaders—administrators and teachers— respond to the results of state assessment systems and the pressure of performance-based accountability? And do those responses seem to matter to achievement outcomes

Presupposition projection as proof construction
Even though Van der Sandt's presuppositions as anaphora approach is empirically successful, it fails to give a formal account of the interaction between world-knowledge and presuppositions. In this paper, an algorithm is sketched which is based on the idea of presuppositions as anaphora. It improves on this approach by employing a deductive system, Constructive Type Theory (CTT), to get a formal handle on the way world-knowledge influences presupposition projection. In CTT, proofs for expressions are explicitly represented as objects. These objects can be seen as a generalization of DRT's discourse markers. They are useful in dealing with presuppositional phenomena which require world-knowledge, such as Clark's bridging examples and Beaver's conditional presuppositions
Differential Expression of Chemokines in a Mouse Model of Wound Healing
Macrophages have a multifaceted role in wound healing. While their initial activity may be in the degradation and elimination of damaged tissue, macrophages also produce and secrete a variety of mediators that can participate in the repair process as well. To perform these functions, macrophages must be recruited to a wound site. Our purpose was to examine the temporal and spatial expression of macrophage chemoattracting cytokines (chemokines) at a surgical wound site. A surgical wound was prepared on the dorsal aspect of B6AFI/J mice. Biopsies were obtained from the wound and a comparable nonwounded area between 6 and 72 hr after wounding. The presence or absence of various chemokine mRNAs was detected by the reverse transcriptase-polymerase chain reaction (RT-PCR). Immunohistochemical staining and in situ RT-PCR determined localization of cells producing chemokines. In wounded tissue, both macrophage chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-1 (MIP -1) were detected; however, the time of expression differed for each molecule. MCP-1 mRNA was detected at 6 hr after wounding, with decreased expression at subsequent time periods. In contrast, MIP-1 messages were not observed until 24 hr after wounding, and steadily increased thereafter. MCP-1 and MIP-1 mRNA and protein were localized predominantly in keratinocytes. The rapid and strong expression of MCP-1 and MIP -1 messages within the wound site suggests a pivotal role for these chemokines in the repair process. The differences in appearance and level of expression over time, however, suggest distinctive functions for each chemokine and indicate that the local milieu, rather than a single cytokine, influences macrophage recruitment and/or activation

Multiple Topical Applications of Arachidonic Acid to Mouse Ears Induce Inflammatory and Proliferative Changes
The response to daily topical applications of arachidonic acid (0.25 – 4 mg/ear/day) to the ears of outbred CD-1 mice was monitored. The first application produced erythema, extravasation of plasma proteins resulting in an increase in ear weight, and some neutrophil accumulation (detected histologically and quantified by myeloperoxidase content). The second application produced minimal edema but did cause erythema and a greater accumulation of neutrophils. Subsequent daily application caused erythema, neutrophil accumulation, and an increase in ear weight predominantly due to cell proliferation (epidermis and connective tissue). Daily applications of other unsaturated fatty acids did not match the response induced by arachidonic acid. Mast cell deficient mice (W/Wv) exhibited a smaller edema response to the first dose of arachidonic acid compared to either their wild-type controls or CD-1 mice. In addition, W/Wv mice exhibited a smaller ear weight increase and myeloperoxidase accumulation following eight daily doses of arachidonic acid. However, epidermal proliferation was similar in all the strains of mice tested. These data suggest that the edema caused by the first topical application of arachidonic acid is partly mast cell mediated. Mast cells also appear to be involved in the neutrophil infiltration induced by multiple topical applications, but not in the epidermal proliferation
