Distinct patterns of peripheral HIV-1-specific interferon- gamma responses in exposed HIV-1-seronegative individuals.

It is unclear how human immunodeficiency virus (HIV) type 1–specific immune responses in exposed seronegative (ESN) individuals differ from those in HIV-1–infected subjects. By use of overlapping peptides spanning Gag, Tat, Nef, Vif, Vpr, and Vpu, peripheral blood mononuclear cells from ESN individuals, their seropositive (SP) partners, and unexposed seronegative control subjects were screened for interferon-? production. Responses were more frequent (95.7% vs. 20%), of a higher magnitude (9-fold), and of wider breadth (median number of peptides recognized, 18 vs. 2.5) in SP than in ESN individuals. Peptides recognized by ESN individuals were less frequently recognized by their SP partners. SP subjects infrequently recognized peptides from Vif, and such responses were subdominant; among ESN individuals, this HIV-1 protein was most frequently recognized. Immunodominant peptides recognized by SP subjects tended to be from relatively conserved regions, whereas peptides recognized by ESN individuals were associated with slow disease progression.

The Nineteenth Century Law of the Sea and the British Abolition of the Slave Trade

This study focuses on British attempts during the nineteenth century to outlaw the Atlantic Slave Trade internationally, for which it was successful, after seventy-five years of effort. It considers the lack of willingness to allow Great Britain, at the Congress of Vienna and during the Concert of Europe, to establish a universal treaty outlawing the slave trade. As a result, this mandated a change in British tactics, which would ultimately prove to be successful – the establishment of a web of bilateral agreements which came to included all maritime powers. The study then moves on to consider the evolution of these bilateral agreements while highlighting the relationship between Great Britain and States (Brazil, France, Portugal and the United States) which were obstinate in their willingness to join this bilateral regime. Finally, consideration is given to the move towards the establishment of the 1890 General Act of Brussels; and thus the conclusion of the decades long British foreign policy objective of a universal instrument meant to suppress the Atlantic Slave Trade.

UK Power Sector Challenge to National Allocation Plan Under the EU Emissions Trading Scheme Refused by the European Court of Justice

In Case T-130/06 Drax Power and others v European Commission, the Court of First Instance held that an application by Drax Power and others for annulment of Commission Decision (C(2006)426 final of 22 February 2006 concerning a proposed amendment to the National Allocation Plan notified by the UK in accordance with the EU Emissions Trading Directive was inadmissable. The Court ruled that the applicants could not be considered to be 'directly concerned' by the contested decision within the meaning of the fourth paragraph of Article 230 of the European Treaty, on legal standing: 'Any natural or legal person may, under the same conditions, institute proceedings against a decision addressed to that person or against a decision, which, although in the form of a regulation or a decision addressed to another persion, is of direct and individual concern to the former...'

Enforcing Member State Compliance with EU Environmental Law: A Critical Evaulation of the Use of Financial Penalties

The 1993 Treaty on European Union finally closed a legal vacuum in
EU law, by giving the Court the power to impose financial penalties to
enforce compliance with its judgments. Today, this power is found
within Article 260(2) of the Treaty on the Functioning of the
European Union. Drawing upon case law, this article examines the
role that the Court’s enforcement powers have played in relation to
EU environmental law. It argues that EU law has yet to make full use
of their potential. The article commences with the Commission and
questions whether it has sufficient resources to carry out its functions
under Article 260(2). The article also examines the ongoing problem of
Member State delay in complying with Court judgments and the
weight given to environmental considerations in the Court’s decision
making on financial penalties. The article concludes by examining the
implications of the Lisbon Treaty.

Loss of functionally unique species may gradually undermine ecosystems

Functionally unique species contribute to the functional diversity of natural systems, often enhancing ecosystem functioning. An abundance of weakly interacting species increases stability in natural systems, suggesting that loss of weakly linked species may reduce stability. Any link between the functional uniqueness of a species and the strength of its interactions in a food web could therefore have simultaneous effects on ecosystem functioning and stability. Here, we analyse patterns in 213 real food webs and show that highly unique species consistently tend to have the weakest mean interaction strength per unit biomass in the system. This relationship is not a simple consequence of the interdependence of both measures on body size and appears to be driven by the empirical pattern of size structuring in aquatic systems and the trophic position of each species in the web. Food web resolution also has an important effect, with aggregation of species into higher taxonomic groups producing a much weaker relationship. Food webs with fewer unique and less weakly interacting species also show significantly greater variability in their levels of primary production. Thus, the loss of highly unique, weakly interacting species may eventually lead to dramatic state changes and unpredictable levels of ecosystem functioning.

Design and experimental validation of liquid crystal-based reconfigurable reflectarray elements with improved bandwith in F-band

A reconfigurable reflectarray which exploits the dielectric anisotropy of liquid crystals (LC) has been designed to operate in the frequency range from 96 to 104 GHz. The unit cells are composed of three unequal length parallel dipoles placed above an LC substrate. The reflectarray has been designed using an accurate model which includes the effects of anisotropy and inhomogeneity. An effective permittivity that accounts for the real effects of the LC has also been used to simplify the analysis and design of the unit cells. The geometrical parameters of the cells have been adjusted to simultaneously improve the bandwidth, maximize the tunable phase-range and reduce the sensitivity to the angle of incidence. The performance of the LC based unit cells has been experimentally evaluated by measuring the reflection amplitude and phase of a reflectarray consisting of 52x54 identical cells. The good agreement between measurements and simulations validate the analysis and design techniques and demonstrate the capabilities of the proposed reflectarray to provide beam scanning in F band.

Sovereignty, Article 4(2) TEU and the Respect of National Identities: Swinging the Balance of Power in Favour of the Member States?

The question of whether and to what extent sovereignty has been transferred to the European Union (EU) from its Member States remains a central debate within the EU and is interlinked with issues such as Kompetenz-Kompetenz, direct effect and primacy. Central to any claim to sovereignty is the principle of primacy, which requires that Member States uphold EU law over national law where there is a conflict. However, limitations to primacy can traditionally be found in national jurisprudence and the Maastricht Treaty introduced a possible EU limitation with the requirement that the EU respect national identities of Member States. The Lisbon Treaty provided only minimal further support to the principle of primacy whilst simultaneously developing the provision on national identities, now found within Article 4(2) TEU. There are indications from the literature, national constitutional courts and the Court of Justice of the EU that the provision is gathering strength as a legal tool and is likely to have a wider scope than the text might indicate. In its new role, Article 4(2) TEU bolsters the Member States’ claim to sovereignty and the possibility to uphold aspects crucial to them in conflict with EU law and the principle of primacy. Consequently, it is central to the relationship between the constitutional courts of the Member States and the CJEU, and where the final elements of control remain in ‘hard cases’. However, it does so as part of EU law, thereby facilitating the evasion of direct fundamental conflicts and reflecting the concept of constitutional pluralism.

Why do national court judges refer to human rights treaties?: A comparative international law analysis of CEDAW

An analysis was conducted of 325 national judicial decisions across 55 jurisdictions, in which CEDAW was referred to in the reported decision. Despite predictions to the contrary based on previous scholarship, significant variations between courts in their interpretation of CEDAW occurred relatively infrequently, courts referred relatively seldom to interpretations of CEDAW by other national courts, and there was little evidence of transnational dialogic approaches to judging. An analysis of these results suggests that domestic judges invoking CEDAW act primarily as domestic actors who use international law in order to advance domestic goals, rather than acting primarily as agents of the international community in applying CEDAW domestically, or contributing to the transnational shaping of international law to suit national interests. The Article suggests an understanding of the domestic implementation of a human rights treaty as not only law, but a unique kind of law that performs a particular function, in light of its quality as something akin to hard and soft law simultaneously.
