Sheaf representations of MV-algebras and lattice-ordered abelian groups via duality

We study representations of MV-algebras -- equivalently, unital lattice-ordered abelian groups -- through the lens of Stone-Priestley duality, using canonical extensions as an essential tool. Specifically, the theory of canonical extensions implies that the (Stone-Priestley) dual spaces of MV-algebras carry the structure of topological partial commutative ordered semigroups. We use this structure to obtain two different decompositions of such spaces, one indexed over the prime MV-spectrum, the other over the maximal MV-spectrum. These decompositions yield sheaf representations of MV-algebras, using a new and purely duality-theoretic result that relates certain sheaf representations of distributive lattices to decompositions of their dual spaces. Importantly, the proofs of the MV-algebraic representation theorems that we obtain in this way are distinguished from the existing work on this topic by the following features: (1) we use only basic algebraic facts about MV-algebras; (2) we show that the two aforementioned sheaf representations are special cases of a common result, with potential for generalizations; and (3) we show that these results are strongly related to the structure of the Stone-Priestley duals of MV-algebras. In addition, using our analysis of these decompositions, we prove that MV-algebras with isomorphic underlying lattices have homeomorphic maximal MV-spectra. This result is an MV-algebraic generalization of a classical theorem by Kaplansky stating that two compact Hausdorff spaces are homeomorphic if, and only if, the lattices of continuous [0, 1]-valued functions on the spaces are isomorphic.

Fall-related emergency department admission: fall environment and settings and related injury patterns in 6357 patients with special emphasis on the elderly

PRINCIPALS Throughout the world, falls are a major public health problem and a socioeconomic burden. Nevertheless there is little knowledge about how the injury types may be related to the aetiology and setting of the fall, especially in the elderly. We have therefore analysed all patients presenting with a fall to our Emergency Department (ED) over the past five years. METHODS Our retrospective data analysis comprised adult patients admitted to our Emergency Department between January 1, 2006, and December 31, 2010, in relation to a fall. RESULTS Of a total of 6357 patients 78% (n = 4957) patients were younger than 75 years. The main setting for falls was patients home (n = 2239, 35.3%). In contrast to the younger patients, the older population was predominantly female (56.3% versus 38.6%; P < 0.0001). Older patients were more likely to fall at home and suffer from medical conditions (all P < 0.0001). Injuries to the head (P < 0.0001) and to the lower extremity (P < 0.019) occurred predominantly in the older population. Age was the sole predictor for recurrent falls (OR 1.2, P < 0.0001). CONCLUSION Falls at home are the main class of falls for all age groups, particularly in the elderly. Fall prevention strategies must therefore target activities of daily living. Even though falls related to sports mostly take place in the younger cohort, a significant percentage of elderly patients present with falls related to sporting activity. Falls due to medical conditions were most likely to result in mild traumatic brain injury.

Bacterial infections in cirrhosis: a position statement based on the EASL Special Conference 2013.

Bacterial infections are very common and represent one of the most important reasons of progression of liver failure, development of liver-related complications, and mortality in patients with cirrhosis. In fact, bacterial infections may be a triggering factor for the occurrence of gastrointestinal bleeding, hypervolemic hyponatremia, hepatic encephalopathy, kidney failure, and development of acute-on-chronic liver failure. Moreover, infections are a very common cause of repeated hospitalizations, impaired health-related quality of life, and increased healthcare costs in cirrhosis. Bacterial infections develop as a consequence of immune dysfunction that occurs progressively during the course of cirrhosis. In a significant proportion of patients, infections are caused by gram-negative bacteria from intestinal origin, yet gram-positive bacteria are a frequent cause of infection, particularly in hospitalized patients. In recent years, infections caused by multidrug-resistant bacteria are becoming an important clinical problem in many countries. The reduction of the negative clinical impact of infections in patients with cirrhosis may be achieved by a combination of prophylactic measures, such as administration of antibiotics, to reduce the occurrence of infections in high-risk groups together with early identification and management of infection once it has developed. Investigation on the mechanisms of altered gut microflora, translocation of bacteria, and immune dysfunction may help develop more effective and safe methods of prevention compared to those that are currently available. Moreover, research on biomarkers of early infection may be useful in early diagnosis and treatment of infections. The current manuscript reports an in-depth review and a position statement on bacterial infections in cirrhosis.

Isotopic signature of specific biomarkers derived from anaerobic methanotrophic archaea (ANME groups) and sulphate-reducing bacteria (SRB) at different cold seep provinces

Anaerobic methane-oxidizing microbial communities in sediments at cold methane seeps are important factors in controlling methane emission to the ocean and atmosphere. Here, we investigated the distribution and carbon isotopic signature of specific biomarkers derived from anaerobic methanotrophic archaea (ANME groups) and sulphate-reducing bacteria (SRB) responsible for the anaerobic oxidation of methane (AOM) at different cold seep provinces of Hydrate Ridge, Cascadia margin. The special focus was on their relation to in situ cell abundances and methane turnover. In general, maxima in biomarker abundances and minima in carbon isotope signatures correlated with maxima in AOM and sulphate reduction as well as with consortium biomass. We found ANME-2a/DSS aggregates associated with high abundances of sn-2,3-di-O-isoprenoidal glycerol ethers (archaeol, sn-2-hydroxyarchaeol) and specific bacterial fatty acids (C16:1omega5c, cyC17:0omega5,6) as well as with high methane fluxes (Beggiatoa site). The low to medium flux site (Calyptogena field) was dominated by ANME-2c/DSS aggregates and contained less of both compound classes but more of AOM-related glycerol dialkyl glycerol tetraethers (GDGTs). ANME-1 archaea dominated deeper sediment horizons at the Calyptogena field where sn-1,2-di-O-alkyl glycerol ethers (DAGEs), archaeol, methyl-branched fatty acids (ai-C15:0, i-C16:0, ai-C17:0), and diagnostic GDGTs were prevailing. AOM-specific bacterial and archaeal biomarkers in these sediment strata generally revealed very similar d13C-values of around -100 per mill. In ANME-2-dominated sediment sections, archaeal biomarkers were even more 13C-depleted (down to -120 per mill), whereas bacterial biomarkers were found to be likewise 13C-depleted as in ANME-1-dominated sediment layers (d13C: -100 per mill). The zero flux site (Acharax field), containing only a few numbers of ANME-2/DSS aggregates, however, provided no specific biomarker pattern. Deeper sediment sections (below 20 cm sediment depth) from Beggiatoa covered areas which included solid layers of methane gas hydrates contained ANME-2/DSS typical biomarkers showing subsurface peaks combined with negative shifts in carbon isotopic compositions. The maxima were detected just above the hydrate layers, indicating that methane stored in the hydrates may be available for the microbial community. The observed variations in biomarker abundances and 13C-depletions are indicative of multiple environmental and physiological factors selecting for different AOM consortia (ANME-2a/DSS, ANME-2c/DSS, ANME-1) along horizontal and vertical gradients of cold seep settings.

The Civil Society Forum of the Eastern Partnership four years on: Progress, challenges and prospects. CEPS Special Report, January 2014

Established in 2009, during the Eastern Partnership Summit in Prague, the Eastern Partnership Civil Society Forum supports the development of civil society organisations from the EU-28 and the six Partnership countries, namely Armenia, Azerbaijan, Belarus, Georgia, Moldova and Ukraine. After four years of operation, the Secretariat of the Forum’s Steering Committee commissioned CEPS to conduct a comprehensive evaluation of its programme. This report singles out the institutionalisation and socialisation inculcated among its members as the Forum’s greatest accomplishment. In contrast to its internal developments, it argues that the external policy successes of the Forum remain modest. This report is the first attempt to conduct an in-depth assessment of the Forum's Annual Assembly, the Steering Committee and its Secretariat, the Working Groups and National Platforms. Ten actionable recommendations are put forward aimed at improving the Civil Society Forum’s standing and performance.

Economic Incentives for Indirect TTIP Spillovers. CEPS Special Report No. 94/October 2014 [TTIP Series No. 2]

A deep, comprehensive and ambitious TTIP should not undermine or otherwise negatively affect the WTO and its signatories. Among other things, this means that trade diversion ought to be minimised and positive spillovers stimulated. The present CEPS Special Report provides some elementary quantification, which helps to understand the economic incentives for third countries to seek regulatory alignment with TTIP results, where relevant, and for which TTIP should be ‘open’. It focuses on ‘indirect’ spillovers and employs a rather aggregate economic approach. We find that, of three groups of countries that are important for trade with the EU and the US, the ‘closest’ neighbours (NAFTA, EEA, Switzerland and Turkey) exhibit powerful incentives to align so as to benefit from positive spillovers. This is less clear for two other groups. Of the (seven) ‘biggest traders’ (in manufactured goods, for which spillovers matter most), China turns out to have the greatest interest in alignment in selected sectors, followed by Israel, Japan and South Korea. Whereas the latter three either have or are negotiating FTAs with the US and the EU, precisely China has none and remains outside TPP as well. In terms of sectors, the chemical sector followed by electronic equipment are by far the most important, with agro-products and fish as a good third (SPS issues). However, in chemicals and electrical equipment, the TTIP negotiations so far, and recent US/EU regulatory cooperation, do not indicate an ambitious approach, which could reduce regulatory barriers to market access drastically.

Who calls the shots in the committees of the new European Parliament? CEPS Special Report No. 97, 21 November 2014

This CEPS Special Report analyses the composition of the 20 committees in the new European Parliament and how representative they are of the 28 member states, identifying which policy areas or committees are of particular interest to MEPs from certain countries. It also examines the allocation of committee chairs and party coordinator positions to assess whether the country of origin matters and if so, why. The study reveals that in general the countries’ share of representatives in the committees is very similar in most of the cases to their representation in Parliament. Still, some policy areas have a special relevance for some countries and attract their MEPs in larger numbers. Due to the procedure used in the allocation of the committee chairs, which favours the largest political groups and the largest national parties within them, MEPs from larger member states tend to hold most of these coveted positions. The internal process followed by the political groups in appointing their coordinators in the respective committees is predisposed towards MEPs with seniority, experience and good connections. All in all, the strategic relevance that national parties attach to these positions makes a difference.

The Impact of the Collaborative Economy on the Labour Market. CEPS Special Report No. 138, June 2016

The digitalisation of work is creating new ways of intermediating work, with for example platforms intermediating work between individuals online. These so-called online collaborative platforms have the potential to fundamentally change the labour market, but for the moment, with an estimated 100,000 active workers or 0.05% of total employees in the EU, they do not seem to have a large impact on the offline/traditional labour market or the create/destroy impetus. This paper analyses the direct and indirect impact of the collaborative economy on the labour market. The findings, based on a collection of empirical studies, suggest that most workers do not earn their main income through online platforms and they obtain earnings from different types of platforms. Earnings from physical/local services are, in general, substantially higher than virtual services that can potentially be delivered globally. The paper also assesses the conditions, number of hours worked and employment status, compared to the offline labour market, and finds shows large differences across types of workers, platforms, and countries. The emergence of online collaborative platforms poses some challenges and opportunities for policy-makers. On the one hand, they may be challenged to ensure minimum remuneration, fair evaluation, tax declaration and social protection, and reduction of the administrative burden. On the other hand, the new technologies may provide opportunities to (partially) liberate some professional services and activate specific groups at a distance away from the labour market. This paper was commissioned by the European Commission as input into its European Agenda for the Collaborative Economy. This Ag

The bright and dark sides of individual and group innovation:A Special Issue introduction

This introduction essay proposes a challenging program for researchers eager to explore factors and process mechanisms contributing to the benefits and costs individuals and groups incur from pursuing innovative approaches. With respect to individual innovation, such moderating factors might be found in the characteristics of the innovative idea, the innovator, co-workers, supervisors, the broader organizational context, and in national culture. Examples of factors that are likely to shape the beneficial and detrimental outcomes of group innovation include knowledge, skills and ability of group members, group tenure, diversity among group members, group processes (clarifying group objectives, participation, constructive management of competing perspectives), and external demands on groups. This Special Issue contains a state-of-the-science paper, three articles dealing with the benefits and costs of individual innovation, and three articles addressing the bright and dark sides of group innovation.

The making of an ideology of the third way:the evolution of christian democracy in Germany (with special reference to 1945-49)

This study investigates the search for the third way in the history of German Christian Democracy. Today, in the United Kingdom, the 'third way' is seen as a new phenomenon, a synthesis of post-war belief in the welfare state and neo-liberal conservatism. Yet it insufficiently acknowledges that the origins of third way thinking, the marriage of social justice with free market economics, of individualism with collective responsibility, are found in the early philosophies of Catholic Social Theory and Protestant Social Ethical Teaching in Germany. This study shows that in the hundred years from the 1840s to the end of the 1940s, there were Catholic and Protestant socio-ethical thinkers and political reformists in Germany who attempted to bridge the philosophical differences between liberalism and socialism, to develop a socio-economic order based on Christian moral values. It will focus on the period 1945-1949, when the CDU was founded as the first interdenominational, Christian party. The study provides the first comprehensive account of the political debates in Christian democratic groups in the Soviet, British, French and American allied occupied zones, also giving equal attention to the contribution from the Protestant wing, alongside the more widely acknowledged role of Catholics in the birth of the CDU. It examines how Christian Democrats envisaged correcting the aberrations of German history, by uniting all social classes and Christian religions in one all-embracing Volkspartei, and transforming party politics from its earlier obsession with sectarian and ideological interests towards a more pragmatic 'third way' programme. The study argues that through the making of its ideology, the CDU modified the nation's understanding of its history, re-interpreted its traditions, and redefined the meaning and perception of established political philosophies. This reveals how the ambiguity of political terminology, and the flexible practice of 'third way' politics, were an invaluable political resource in the CDU's campaign for unity, ideological legitimisation and political power.

Policy issues in rural areas:an examination with special reference to Cumbria

This thesis develops the requirements of the Cumbria Division of the MAFF to have detailed information on a number of rural topics of particular concern to the area's socia-economic advisory service. Information was generated upon the effects of road developments upon agriculture; the possibility of economic and employment growth through tourism, industry, forestry and agriculture; and upon their relationship with conservation and development control issues generally. A working conference was organised (The Whitbarrow Exercise) to review in specific terms a number of the above problems, in which representatives of the major groups active in rural policy formulation and implementation participated. The study was extended to consider these policy issues on a more prosperous agricultural estate; and in the county of Cumbria as a whole. An examination of the development and likely future impact of agricultural policy upon rural policy generally was also undertaken. All the research was set in the context of an extensive literature review. The results indicate that while state intervention to relieve those problems collectively known as rural deprivation still has an important place in modern rural policy, the scope for such intervention to be successful is limited. Opportunities for employment and wealth creation through tourism, forestry, industry and agriculture are limited for social and economic reasons; developments in these sectors can have adverse effects upon the environment; can compound existing problems; and are often resisted by local people. The lack of success of such ventures indicates continued structural change within rural communities, with some adverse effects for the less privileged members. Recognising this it is argued that fural policy seeks to adapt to, rather than attempt to fundamentally alter inevitable change, recognising that in the long term social and structural problems will resolve themselves. It is further argued that a reduction in state support for agriculture appears inevitable, and this can bring considerable conservation benefits, even in upland areas where positive links between agriculture and conservation have been found by some commentators. It is also argued that for social and economic reasons, and because of the declining importance of agricultural land, a vigorous landscape and ecological conservation policy is pursued by planning authorities and is reasonable. With regard to road developments on agricultural land, the research has shawn that although it is the norm far the agricultural community to experience severe difficulty during developments, these can be overcame by increasing the resources of professional expertise available to affected farmers. This indicates a possible important increased role for the MAFF in the development process.

Insect pest control research : the analysis of historical trends with special reference to scientometric analysis

The thesis investigates the value of quantitative analyses for historical studies of science through an examination of research trends in insect pest control, or economic entomology. Reviews are made of quantitative studies of science, and historical studies of pest control. The methodological strengths and weaknesses of bibliometric techniques are examined in a special chapter; techniques examined include productivity studies such as paper counts, and relational techniques such as co-citation and co-word analysis. Insect pest control is described. This includes a discussion of the socio-economic basis of the concept of `pest'; a series of classifications of pest control techniques are provided and analysed with respect to their utility for scientometric studies. The chemical and biological approaches to control are discussed as scientific and technological paradigms. Three case studies of research trends in economic entomology are provided. First a scientometric analysis of samples of chemical control and biological control papers; providing quantitative data on institutional, financial, national, and journal structures associated with pest control research fields. Second, a content analysis of a core journal, the Journal of Economic Entomology, over a period of 1910-1985; this identifies the main research innovations and trends, in particular the changing balance between chemical and biological control. Third, an analysis of historical research trends in insecticide research; this shows the rise, maturity and decline of research of many groups of compounds. These are supplemented by a collection of seven papers on scientometric studies of pest control and quantitative techniques for analysing science.
