Reorganization of an arid ecosystem in response to recent climate change

Natural ecosystems contain many individuals and species interacting with each other and with their abiotic environment. Such systems can be expected to exhibit complex dynamics in which small perturbations can be amplified to cause large changes. Here, we document the reorganization of an arid ecosystem that has occurred since the late 1970s. The density of woody shrubs increased 3-fold. Several previously common animal species went locally extinct, while other previously rare species increased. While these changes are symptomatic of desertification, they were not caused by livestock grazing or drought, the principal causes of historical desertification. The changes apparently were caused by a shift in regional climate: since 1977 winter precipitation throughout the region was substantially higher than average for this century. These changes illustrate the kinds of large, unexpected responses of complex natural ecosystems that can occur in response to both natural perturbations and human activities.

Dynamics of mobile element activity in chalcone synthase loci in the common morning glory (Ipomoea purpurea)

Mobile element dynamics in seven alleles of the chalcone synthase D locus (CHS-D) of the common morning glory (Ipomoea purpurea) are analyzed in the context of synonymous nucleotide sequence distances for CHS-D exons. By using a nucleotide sequence of CHS-D from the sister species Ipomoea nil (Japanese morning glory [Johzuka-Hisatomi, Y., Hoshino, A., Mori, T., Habu, Y. & Iida, S. (1999) Genes Genet. Syst. 74, 141–147], it is also possible to determine the relative frequency of insertion and loss of elements within the CHS-D locus between these two species. At least four different types of transposable elements exist upstream of the coding region, or within the single intron of the CHS-D locus in I. purpurea. There are three distinct families of miniature inverted-repeat transposable elements (MITES), and some recent transpositions of Activator/Dissociation (Ac/Ds)-like elements (Tip100), of some short interspersed repetitive elements (SINEs), and of an insertion sequence (InsIpCHSD) found in the neighborhood of this locus. The data provide no compelling evidence of the transposition of the mites since the separation of I. nil and I. purpurea roughly 8 million years ago. Finally, it is shown that the number and frequency of mobile elements are highly heterogeneous among different duplicate CHS loci, suggesting that the dynamics observed at CHS-D are locus-specific.

Ion channel genes and human neurological disease: Recent progress, prospects, and challenges

What do epilepsy, migraine headache, deafness, episodic ataxia, periodic paralysis, malignant hyperthermia, and generalized myotonia have in common? These human neurological disorders can be caused by mutations in genes for ion channels. Many of the channel diseases are “paroxysmal disorders” whose principal symptoms occur intermittently in individuals who otherwise may be healthy and active. Some of the ion channels that cause human neurological disease are old acquaintances previously cloned and extensively studied by channel specialists. In other cases, however, disease-gene hunts have led the way to the identification of new channel genes. Progress in the study of ion channels has made it possible to analyze the effects of human neurological disease-causing channel mutations at the level of the single channel, the subcellular domain, the neuronal network, and the behaving organism.

Think globally, translate locally: What mitotic spindles and neuronal synapses have in common

Early metazoan development is programmed by maternal mRNAs inherited by the egg at the time of fertilization. These mRNAs are not translated en masse at any one time or at any one place, but instead their expression is regulated both temporally and spatially. Recent evidence has shown that one maternal mRNA, cyclin B1, is concentrated on mitotic spindles in the early Xenopus embryo, where its translation is controlled by CPEB (cytoplasmic polyadenylation element binding protein), a sequence-specific RNA binding protein. Disruption of the spindle-associated translation of this mRNA results in a morphologically abnormal mitotic apparatus and inhibited cell division. Mammalian neurons, particularly in the synapto-dendritic compartment, also contain localized mRNAs such as that encoding α-CaMKII. Here, synaptic activation drives local translation, an event that is involved in synaptic plasticity and possibly long-term memory storage. Synaptic translation of α-CaMKII mRNA also appears to be controlled by CPEB, which is enriched in the postsynaptic density. Therefore, CPEB-controlled local translation may influence such seemingly disparate processes as the cell cycle and synaptic plasticity.

The autonomy of the EU legal order and the law-making activities of international organizations. Some examples regarding the Council most recent practice. Research Papers in Law 03/2012

[Introduction.] It is generally believed that while the principle of the autonomy of the EU legal order, in the sense of constitutional and institutional autonomy that is to say what concerns the autonomous decision-making of the EU, has been clearly strengthened by the most recent jurisprudence of the Court of Justice (eg. Moxplant3, Intertanko or the Kadi/Al Baraakat judgements or the Opinion 1/2009 of the CJEU etc.) as well as, in my opinion, in many aspects by the Treaty of Lisbon, it is still valid to add that the principle of a favourable approach, stemming from the Court jurisprudence, for the enhanced openness of the EU legal order to international law has remained equally important for the EU4. On the other hand, it should be also seen that in a globalized world, and following the increased role of the EU as an international actor, its indispensable and crucial role concerning the creation of world (legal) order in many policy fields ( for example let's think about the G20 issues, the global economic and financial crisis, the role of the EU in promoting and protecting human rights worldwide, the implementation of the multilateral or regional conventional law, developed in the framework the UN (e.g. in the field of agriculture or environment etc) or what concerns the Kyoto process on climate change or the conservation of marine biological resources at international level etc), it seems reasonable and justified to submit that the influence, for example, of the law-making activities of the main stakeholder international organizations in the mentioned policy-areas on the EU (especially on the development of its constantly evolving legal order) or vice-versa the influence of the EU law-making practice on these international organizations is significant, in many aspects mutually interdependent and more and more remarkable. This tendency of the 21st century doesn't mean, however, in my view, that the notion of the autonomy of the EU legal order would have been weakened by this increasing interaction between international law and EU law over the passed years. This contribution is going to demonstrate and prove these departuring points by giving some concrete examples from the most recent practice of the Council (all occuring either in the second half of 2009 or after the entry into force of the Lisbon Treaty), and which relate to two very important policy areas in the EU, namely the protection of human rights and the Common Fishery Policy.

Recent developments in the synthesis of novel xanthone-1,2,3-triazole dyads

The development of multi-target drugs for treating complex multifactorial diseases constitutes an active research ield. This kind of drugs has gained much importance as alternative strategy to combination therapy (“cocktail drugs”).1 A common way to design them brings together two different pharmacophores in one single molecule (so-called dyads). Following this idea and being aware that xanthones2 and 1,2,3-triazoles3 possess important pharmacological properties, we combined these two heterocycles in one molecule to create new dyads with improved therapeutic potential. In this work, new xanthone-1,2,3-triazole dyads were prepared from novel (E)-2-(4-arylbut-1-en-3-yn-1-yl)chromones by two different approaches to evaluate their eficiency and sustainability. Both methodologies involved Diels-Alder reactions to build the xanthone core, which were optimized using microwave irradiation as alternative heating method, and 1,3-dipolar cycloadditions to insert the 1,2,3-triazole moiety (Figure 1).4 All final and intermediate compounds were fully characterized by 1D and 2D NMR techniques.

The Common Agricultural Policy: The Future of the CAP and why real reform will never happen. EUMA Paper Vol. 6 No. 7, May 2010

This paper sets out to examine the Common Agricultural Policy (CAP) of the European Union from its inception to present day 1. Specifically, this paper seeks to answer the following questions: (1) What long-term effects, if any, did the circumstances surrounding, and leading up to the formation of the CAP have; (2) What have internal and external responses been to the CAP; (3) How has the CAP responded to major events both internally (within the European Union), and externally (internationally); (4) What affect does the recently implemented Lisbon Treaty2 have on the CAP, and (5) What is the future of the CAP and CAP reform? In order to answer these questions this paper begins with the contention that the CAP is in fact the largest and strongest driving force of EU expansion. In support of this proposition, this paper first examines the circumstances and events leading to the creation of the CAP in the European Community. Second, this paper examines what long-term effects the circumstances surrounding the CAP’s inception have had on the policy, particularly calling attention to the disproportionate Franco-German CAP benefits. Third, the paper then examines how the CAP has responded to historical events that have had significant effects on the European community, particularly EU expansion, the implementation of the Lisbon Treaty, and the recent worldwide economic crisis. Finally, this paper examines common criticisms of and conflicts surrounding the CAP, both internally and externally, and argues that CAP reform, at least within the current institutional framework of the European Union, can never truly occur.

Europe on the Road to the Third Stage of EMU: Recent Evidence. CES Germany & Europe Working Papers, No. 07.2, 1996

The paper deals with Europe's effort to proceed to the thud stage of EMU and establish a common currency. It is argued that the success of the common currency experiment will greatly depend on the fulfillment of the Optimum Currency Area (OCA) criteria, on the adoption of the proper adjustment policies as well as on the political desirability of the project. The paper is organized as follows: Section 1 deals briefly with the index of criteria that define an OCA. Section 2 examines the extent to which Europe experiences common demand disturbances, while sections 3 and 4 focus on evidence about the mobility of factors of production across Europe, namely labor and capital. Section 5 examines the possibility of an increase in trade volume across the EU under fixed exchange rates or a common currency regime. Section 6 sheds light on the possibility of the EURO (the ex-ECU} to become a vehicle currency in the international financial system, and Section 7 is concerned with the benefits and costs of the establishment of a European Central Bank (ECB), paying special attention to seigniorage revenues. Section 8 deals with the necessity of establishing an EU federal mechanism facilitating adjustment. Section 9 sketches out a proper role for a hegemonic power in a common currency regime. Finally, section 10 examines EMU prospects during the transitional period. The paper closes with some concluding remarks, where the role of politics and coordination of economic policies are particularly emphasized as of cardinal importance on the road to the third stage of EMU.

Recent Changes in European Welfare State Services: A Comparison of Child Care Politics in the U.K., Sweden, Germany, and the Netherlands. CES Germany & Europe Working Papers, No. 07.6, 1997

This paper examines recent policies and politics of services, in particular child care services in European welfare states. It is argued that social (care) services are becoming an increasingly political issue in postindustrial societies and are at the very center of welfare-state restructuring. Some countries have recently developed new policy pro­ grams for child care-but there are important differences among these programs. To understand these differences as well as some common features, the paper argues that it is necessary to examine the institutional organization of child care and short-term political factors as well as the rationales articulated in political debates to support or im­ pede various policies. The paper concludes that a comprehensive system of child care provisions is still far off in most countries, despite a rhetoric of choice and postindustrial care and labor-market patterns.

The Common Security and Defence Policy: National Perspectives. Egmont Paper No. 79, May 2015

FOREWORD. When one looks at the present state of the CSDP, one cannot help but look on with disenchantment at the energy that appears to have abandoned both institutions and Member States. Commentators increasingly take for granted that nothing much should be expected from this field of EU policy. The reasons for this state of mind are well known: the recent economic and financial strains, which have impacted all EU action since 2008, means that most of the Member States will struggle to keep their defence budgets at their present level in the future, and we may even see reductions. Furthermore, and to put it mildly, most of the recent CSDP operations have also experienced a lack of enthusiasm. Adding to this overall trend, the EU is far from presenting a common vision of what security and defence should really mean. Many of the Member States do not want to be involved in all of today’s international turmoils, and they rarely share the strategic culture which inspires those Member States who see themselves as having special responsibilities in dealing with these crises. In the end it may be that Member States diverge fundamentally on the simple question of whether it is relevant for the EU to engage in most of the ‘hot’ crises Europe faces; many prefer to see Europe as a soft power, mostly dedicated to intervening on less dramatic fronts and more inclined to mend than to fight. For whatever reason given, it remains that if there is a lack of common understanding on what CSDP should really be about, it should not come as a surprise if this policy is presently in stalemate. As an additional blow, the Ukrainian crisis, which dragged on for the whole of last year, could only add to the downward spiral the EU has been experiencing, with a new Russia aggressively confronting Europe in a manner not too distant from the Cold War days. This attitude has triggered the natural reaction among EU Member States to seek reassurances from NATO about their own national security. Coupled with the return of France a few years ago into the integrated military command, NATO’s renewed relevance has sent a strong message to Europe about the military organisation’s credibility with regard to collective defence. Surprisingly, this overall trend was gathering momentum at the same time as other more positive developments. The European Council of December 2013 dedicated its main session to CSDP: it underlined Europe’s role as a ‘security provider’ while adopting a very ambitious road map for Europe in all possible dimensions of the security sector. Hence the impression of a genuine boost to all EU institutions, which have been invited to join efforts and give CSDP a reinvigorated efficiency. In the same way, the increasing instability in Europe’s neighbourhood has also called for more EU operations: most recently in Iraq, Libya, Northern Nigeria or South Sudan. Pressure for further EU engagement has been one of the most constant features of the discussions taking place around these crises. Moreover, a growing number of EU partners in Asia, Latin America or Eastern Europe have shown a renewed eagerness to join CSDP missions in what sounds like a vote of confidence for EU capacities. What kind of conclusion should be drawn from this contradictory situation? Probably that the EU has much more potential than it can sometimes figure out itself, if only it would be ready to adapt to the new global realities. But, more than anything else, an enhanced CSDP needs from all Member States strong political will and a clear vision of what they want this policy to be. Without this indispensable ingredient CSDP may continue to run its course, as it does today. It may even grow in efficiency but it will keep lacking the one resource that would definitely help it overcome all the present shortcomings that have prevented Europe from finding its true role and mission through the CSDP. Member States remain central to EU security and defence policy. This is why this collection of essays is so valuable for assessing in no uncertain way the long road that lies ahead for any progress to be made.

Late Eocene to Recent deep-sea benthic foraminifera from the Central equatorial Pacific Ocean

Benthic foraminifers were studied in upper Eocene to Recent core-catcher samples from DSDP Sites 573, 574, and 575. The sites are on a north-south transect from the equator to about 05°N at about 133°W, water depth 4300 to 4600 m. At Site 574 additional samples were used to study the Eocene/Oligocene boundary in detail. About 200 specimens were counted per sample. The fauna is highly diverse (about 50 to 70 species per sample) and is of low dominance. The diversity is not related to age or sub-bottom depth. Many species are cosmopolitan and probably have wide environmental tolerances. Fluctuations in frequency of some taxa (e.g., Nuttallides umbonifera, Epistominella exigua, and Uvigerina spp.) cannot be correlated from one site to another. Several common species (e.g. Oridorsalis umbonatus and Globocassidulina subglobosa) range from late Eocene to Recent. First and last appearances are generally difficult to define precisely because many species are rare. For some species these datums differ from one site to another, but several datum levels are within 1 m.y. at all sites. First and last appearances are most numerous in two intervals, the late Eocene to early Oligocene (about 32 to 37 Ma) and the early to middle Miocene (about 13 to 18.5 Ma). Isotopic events occur within each of these periods of benthic faunal change, but the isotopic events have a shorter duration and start after the initiation of the changes in the fauna. Changes in deep-sea benthic faunal composition are not directly related to short-term oceanographic changes as expressed in isotopic records.

A brief motivational intervention for substance misuse in recent-onset psychosis

Substance misuse is common in early psychosis, and impacts negatively on outcomes. Little is known about effective interventions for this population. We report a pilot study of brief intervention for substance misuse in early psychosis ( Start Over and Survive: SOS), comparing it with Standard Care(SC). Twenty-five in-patients aged 18 - 35 years with early psychosis and current misuse of non-opioid drugs were allocated randomly to conditions. Substance use and related problems were assessed at baseline, 6 weeks and 3, 6 and 12 months. Final assessments were blind to condition. All 13 SOS participants who proceeded to motivational interviewing reported less substance use at 6 months, compared with 58% (7/12) in SC alone. Effects were well maintained to 12 months. However, more SOS participants lived with a relative or partner, and this also was associated with better outcomes. Engagement remained challenging: 39% (16/41) declined participation and 38% (5/13) in SOS only received rapport building. Further research will increase sample size, and address both engagement and potential confounds.

Eye colour: portals into pigmentation genes and ancestry

Several recent papers have tried to address the genetic determination of eye colour via microsatellite linkage, testing of pigmentation candidate gene polymorphisms and the genome wide analysis of SNP markers that are informative for ancestry. These studies show that the OCA2 gene on chromosome 15 is the major determinant of brown and/or blue eye colour but also indicate that other loci will be involved in the broad range of hues seen in this trait in Europeans.

Scaling laws for the critical rupture thickness or common thin films

Despite decades of experimental and theoretical investigation on thin films, considerable uncertainty exists in the prediction of their critical rupture thickness. According to the spontaneous rupture mechanism, common thin films become unstable when capillary waves. at the interfaces begin to grow. In a horizontal film with symmetry at the midplane. unstable waves from adjacent interfaces grow towards the center of the film. As the film drains and becomes thinner, unstable waves osculate and cause the film to rupture, Uncertainty sterns from a number of sources including the theories used to predict film drainage and corrugation growth dynamics. In the early studies, (lie linear stability of small amplitude waves was investigated in the Context of the quasi-static approximation in which the dynamics of wave growth and film thinning are separated. The zeroth order wave growth equation of Vrij predicts faster wave growth rates than the first order equation derived by Sharma and Ruckenstein. It has been demonstrated in an accompanying paper that film drainage rates and times measured by numerous investigations are bounded by the predictions of the Reynolds equation and the more recent theory of Manev, Tsekov, and Radoev. Solutions to combinations of these equations yield simple scaling laws which should bound the critical rupture thickness of foam and emulsion films, In this paper, critical thickness measurements reported in the literature are compared to predictions from the bounding scaling equations and it is shown that the retarded Hamaker constants derived from approximate Lifshitz theory underestimate the critical thickness of foam and emulsion films, The non-retarded Hamaker constant more adequately bounds the critical thickness measurements over the entire range of film radii reported in the literature. This result reinforces observations made by other independent researchers that interfacial interactions in flexible liquid films are not adequately represented by the retarded Hamaker constant obtained from Lifshitz theory and that the interactions become significant at much greater separations than previously thought.
