AbstractWe compare the microscopic anatomy of the mouthparts of representative species of Solifugae, Pseudoscorpiones and Parasitiformes (Acari). Specifically, we focus on the epistome, the labrum, the lateral lips (= endites of the pedipalpal coxae) and the musculature of the pharyngeal suction pump. We provide evidence that the labrum is reduced in Solifugae, but present and functional in Pseudoscorpiones and Acari. The epistome constitutes the entire dorsal face of the rostrosoma in Solifugae, but is internalized into the prosoma in Pseudoscorpiones. In Acari, the epistome shows an ancestral morphology, probably close to the ground pattern of chelicerates. The lateral lips of Solifugae contribute to the ventral face of the rostrosoma and the two lips of the mouth opening. In Solifugae, the ventral rostrosoma also includes a sclerite that might derive from a tritosternum. In Pseudoscorpiones, the lateral lips remain independent of the rostrosoma, they interlock ventral to the rostrosoma forming a perioral space. Here, the rostrosoma has an unpaired ventral lip of unresolved morphological origin, which is, however, clearly distinct from the lateral lips of Solifugae. The pharyngeal suction pump differs in all three clades in attachment, number of muscles and origin of muscles. We interpret the data as evidence for independent, parallel evolution of elements of the ground pattern of the (eu)chelicerate mouth parts. Based on the morphological elements of a common euchelicerate ground plan, the rostrosoma evolved independently in the three clades. We reject earlier hypotheses that consider the rostrosoma a character to support a phylogenetic relationship of the three clades.

Задачей данной статьи является рассмотрение лингвопрагматических особенностей комментариев пользователей социальной сети «Твиттер» на выход Великобритании из ЕС. Анализ данных комментариев с лингвопрагматической точки зрения представляет интерес, так как показывает наиболее актуальную картину отношения пользователей социальных сетей к произошедшему событию. Приоритетными методами анализа лингвопрагматического потенциала Интернет-комментариев для нас являются: описательный метод, метод прагматического анализа, т.е. рассмотрение языкового материала в его непосредственном контексте в функциональном аспекте, метод частичной выборки, метод контекстологического описания. Контекстуальный метод был использован с целью установления особенностей комментариев в среде социальной сети «Твиттер»; описательный метод - для выявления непосредственного отношения пользователей социальных сетей к выходу Великобритании из ЕС; частичной выборки - для отбора наиболее эффективных и целостных комментариев с позиции прагматики и их реализации в данном контексте. Проведённое исследование позволило установить, что большинство людей удовлетворено результатами выхода Великобритании из ЕС и положительно отзывается об этом событии. Об этом свидетельствует как большое количество экспрессивов, использованных в интернет-комментариях в отношении данного события, так и активное употребление в них оценочной лексики. Результаты проведённого исследования могут быть применены в теоретических работах по описанию характеристик речевых актов, в курсе теоретической грамматики, стилистики, прагмалингвистики. The purpose of this article is to review the linguo-pragmatic features of Brexit represented in the comments in Twitter. Their analysis from a linguistic-pragmatic point of view may be of interest, since it shows the most relevant picture of the relationship of social network users for the event. The priority methods for analyzing the linguo-pragmatic potential of Internet comments for us are: a descriptive method, a pragmatic analysis method, i.e. consideration of linguistic material in its immediate context in the functional aspect, partial sampling method, contextual description method. The contextual method was used to establish the characteristics of comments on the Twitter social network; descriptive method was used to identify the direct relationship of social network users to the UK exit from the EU; partial sampling was used to select the most effective and holistic comments from the position of pragmatics and their implementation in this context. The study found that most people are satisfied with the results of the UK exit from the EU and respond positively to this event. The results of the study can be applied in theoretical works on the description of the characteristics of speech acts, in the course of theoretical grammar, stylistics, pragmalinguistics.

VAT is one of the most decisive tax revenues sources in the EU Member States. Due to financial frauds and insufficient tax system, there is a billion loss of EUR every year in the European budget. The article deals with the impact of the tax evasion on economies of the EU Member States. By applying the top-down approach, we observed tax gaps as a quantifier of tax evasion from 2004 to 2017. The period around the economic crisis in 2009 was examined in more detail, as there was a sharp change in the evolution of tax gaps. We constructed a regression model, which examined the relationship of the tax gap and VAT tax revenues to selected determinants of tax evasion. The results showed that tax gaps in the Member States have been growing every year. We also found that there is an increase in tax revenues, but tax liabilities increase to greater extent.

La policía comunitaria es una institución de los pueblos indígenas de Guerrero conocida por su capacidad para enfrentar a la delincuencia y generar alternativas de paz social., através de un sistema de justicia y seguridad autónomo. En los últimos años, sin embargo, el sistema comunitario enfrenta el acoso de actores diversos vinculados al incremento de la violencia y la inseguridad que se vive en el país y especialmente en el estado de Guerrero; dicha situación está impactando a la institucionalidad comunitaria, obligando a su redefinición. En este trabajo destaco aspectos centrales de dicha conflictividad así como las respuestas que han dado los comunitarios para hacer frente a las tareas de justicia y seguridad en el marco de nuevos contextos marcados por el despojo neoliberal y la impunidad de actores estatales y no estatales. En este proceso se actualiza la relación de la policía comunitaria con el Estado revelando el peso de la ambigüedad legal y los juegos del poder así como los usos contra-hegemónicos del derecho para disputar la justicia. ---SEGURANÇA E JUSTIÇA SOB ACOSSO EM TEMPOS DE VIOLÊNCIA NEOLIBERAL: respostas do policiamento comunitário de GuerreroO policiamento comunitário é uma instituição dos Povos Indígenas do Guerrero conhecidos por sua capacidade de lidar com o crime e gerar paz social de forma alternativa, usando um sistema próprio de justiça e segurança. Nos últimos anos, no entanto, o sistema da UE enfrenta assédio de várias autoridades envolvidas no aumento da violência e da insegurança que reina no país e, especialmente, no estado de Guerrero; essa situação está afetando as instituições comunitárias, forçando a sua redefinição. Neste artigo, destaco os principais aspectos do conflito e as respostas que têm a comunidade para lidar com as tarefas da justiça e da segurança no contexto dos novos contextos marcados por pilhagem neoliberal e a impunidade de atores estatais e não estatais. Neste processo, a relação de policiamento comunitário com o estado é atualizada, revelando o peso da ambiguidade e dos jogos de poder legais, além de usos contra-hegemônicos do direito de disputar a justiça.Palavras-chave: violência neoliberal; Guerrero; comunidades indígenas---SECURITY AND JUSTICE UNDER HARASSMENT IN TIMES OF NEOLIBERAL VIOLENCE: responses of the Community Police of GuerreroThe community police is an institution of the Indigenous Peoples of Guerrero known for its ability to deal with crime and generate alternatives for social peace, using a system of justice and self security. In recent years, however, the EU system faces harassment from various people responsible for the increase of violence and insecurity within the country and especially in the state in Guerrero; this situation is impacting instituitions in the community, forcing their redefinition. In this paper I highlight key aspects of the conflict and the community's responses to deal with the tasks of justice and security in new contexts marked by neoliberal plunder and impunity of the state (as well as non state figures). In this process, the relationship of the community police with the state is updated revealing the weight of legal ambiguity and power plays, as well as counter-hegemonic use of the right to dispute justice.key words: neoliberal vilence; Guerrero; indigenous people.


From a study of the anatomy of the different regions of the plant, evidence is found of the relationship of the Araucarineæ to the Cordaitales. In the first place, the presence of a leaf gap opposite the outgoing foliar trace, in all forms whether the leaf be large or small, is taken as indicating the Pteropsid ancestry of these forms and is considered of sufficient importance to preclude the possibility of the Lycopsid connection of the Araucarineæ, of which view Seward has been the recent exponent. The presence of a gap in the cone and in the seedling seems to put the question beyond doubt, since this indicates the ancestral presence of a leaf gap.

This article tries to make sense of Brexit, or otherwise, from a group attachment perspective. It provides a historical analysis of the fluctuating and highly ambivalent relationship of the United Kingdom (UK) with the European Union (EU), so far the most ambitious supranational and transnational group project in the world. But the EU has failed to keep up with some of its founding principles of openness, solidarity and compassion, in the handling of immigration—which has been the most determinant factor in the Brexit vote of June 2016, against a background of financial and migratory crises, as well as unacceptable inequality, nostalgia of sovereign British Empire and rise of English nationalism. The article aims to engage the reader to explore with the author some of the complexity of Brexit thinking and feeling, in the context of a developing EU.

Abstract This qualitative study is aimed at elucidating conceptual metaphors associated with renewable energy sources (further referred to as ‘renewables’) in Ukrainian prime ministers’ (PMs) political discourse. The material derives from a corpus of Ukrainian PMs’ political texts on renewables in Ukraine within the timeframe 2005-2014. The corpus is examined for the presence of conceptual metaphors pertaining to the topic of renewables. Data analysis indicates that from 2005 to 2013 conceptual metaphors involving renewables are embedded in the issues of Ukraine’s adherence to the Kyoto Protocol, the EU directives on renewables, the monetary value of renewables and the role of renewables in Ukraine’s energy security, thus instantiating the conceptual metaphors Renewables as Ukraine’s European Choice, Renewables as a Path to the EU, Renewables as Money and Renewables as Independence respectively. However, the novel metaphor Renewables as Survival is identified in PM Yatsenjuk’s political discourse in 2014. This metaphor is embedded in the context of another conceptual metaphor, Gas as a Weapon, which is present in political discourse involving Russian natural gas export to third countries. Data analysis indicates that the conceptual metaphors Renewables as Survival and Renewables as Independence are in a polyphonic relationship of synergy and contrast with Gas as a Weapon.

Abstract Introduction Changes caused by the rigidity of Parkinson’s Disease (PD) can affect the mandibular musculature. However, few studies have been published about its impact on the oral opening. Objective To analyze the relationship of the vertical extension of the oral opening with muscular rigidity and sociodemographic factors of the elderly with PD. Material and method This is a cross-sectional, quantitative study that collected data from a primary study conducted at the Hospital das Clínicas of the Federal University of Pernambuco in 2018. Data were collected from medical records and from the questionnaire, Research Diagnostic Criterion for Temporomandibular Disorders (RDC/TMD). The sample was composed of 81 parkinsonians and characterized using: sociodemographic variables and the presence or absence of muscular rigidity. The measures of vertical extension of the oral opening evaluated were: mouth opening without assistance and without pain (ABASD), and maximum mouth opening without assistance (AMBSA). The Pearson’s linear correlation and Spearman’s correlation tests were applied to investigate the relationship among the continuous variables. Analyses of association were conducted using simple logistic regression. The level of significance was set at p<0.05. Result Limitation of the oral opening was not related to age or sex. The greatest level of significance was between mouth opening without assistance and without pain and muscular rigidity (p=0.012), and years of schooling (p=0.038). Conclusion The limitation of mouth opening in people with PD was shown to be related to muscular rigidity and fewer years of schooling.

This casenote reviews and discusses the series of decisions regarding sanctions imposed by the UN Security Council against Yassin Abdullah Kadi, as implemented in the EU legal order. In this series of cases, the EU Courts at different times take different positions regarding the relationship of the UN and the EU legal order, as well as their power to review EU acts implementing Security Council sanctions and (indirectly) the sanctions themselves. The series of cases marks a watershed moment in UN Security Council targeted sanctions, forcing EU member states to disobey them and eventually leading to the creation and strengthening of an internal UN review mechanism, the Office of the Ombudsperson.
