Limestone areas of China host remarkable radiations of cave animals. The subterranean trechine beetles (Carabidae: Trechini), the most diverse and modified group of subterranean beetles in the world, are extremely diverse in southern China. The first aphaenopsian trechine beetle, Sinaphaenops mirabilissimus Uéno & Wang, 1991 was reported from a limestone cave in Guizhou province. Up to now, 146 species within 48 genera of aphaenopsian trechine have been described in China after almost three decades. Among them, the genera Giraffaphaenops, Xuedytes, Dongodytes, Sinaphaenops and Pilosaphaenops from northwest Guangxi and south Guizhou are the most modified troglobitic trechine beetles known so far in the world. They are remarkable by their morphology combining extremely slender body and elongated appendages. Some of them are diversified or quite widespread, which is not the case of Xuedytes Tian & Huang, 2017, a remarkable monospecific genus known from a single locality so far. In addition to the surveys and collection of specimens, an integrative approach combining the study of systematics, phylogeny, diversification and biogeography patterns of the cave trechine beetles in China is on the way, in order to understand the origin of the remarkable biodiversity and evolutionary success of this group.

Coleoptera is one of the most successful groups among the subterranean fauna. Within Carabidae, 25 tribes have been reported in subterranean habitats, including the first representative of the tribe Patrobini, just described from Southern China. Amongst them, Trechini is the most diverse and cave-specialized group, and the numerous lineages of this group which have diversified underground make it an excellent model for the study of evolutionary mechanisms. In China, 152 species within 52 genera of Trechini have been described so far. In order to unveil the relationships and origin of this remarkable biodiversity and to understand the evolutionary success of this group, we infer the first phylogeny of the group by using molecular sequence data from four genes (two mitochondrial markers: cox1 and 16S; plus two nuclear: 18S and 28S). We found that the Chinese cave Trechini do not form a monophyletic clade and we identified three main independent subterranean clades. To define the systematic position of the main clades on a worldwide scale, we gathered other Trechini sequence data from different lineages and part of the world. The preliminary results will be presented in this talk.

Abstract. This research took place just after the end of the protests following the killing of a 16-year-old boy by a policeman in Greece in December 2008. Participants (N = 224) were 16-year-olds in different schools in Attiki. Informed by the Politicized Collective Identity Model ( Simon & Klandermans, 2001 ), a questionnaire measuring grievances, adversarial attributions, emotions, vulnerability, identifications with students and activists, and questions about justice and Greek society in the future, as well as about youngsters’ participation in different actions, was completed. Four profiles of the participants emerged from a cluster analysis using representations of the conflict, emotions, and identifications with activists and students. These profiles differed on beliefs about the future of Greece, participants’ economic vulnerability, and forms of participation. Importantly, the clusters corresponded to students from schools of different socioeconomic areas. The results indicate that the way young people interpret the events and the context, their levels of identification, and the way they represent society are important factors of their political socialization that impacts on their forms of participation. Political socialization seems to be related to youngsters’ position in society which probably constitutes an important anchoring point of their interpretation of the world.

This article considers how pre-existing music has been employed in British cinema, paying particular attention to the diegetic/nondiegetic boundary and notions of restraint. It explores the significance of the distinction between diegetic music, which exists in the world of the narrative, and nondiegetic music, which does not. It analyses the use of pre-existing operatic music in two British films of the same era and genre: Kind Hearts and Coronets (1949) and The Importance of Being Earnest (1952), and demonstrates how seemingly subtle variations in the way music is used in these films produce markedly different effects. Specifically, it investigates the meaning of the music in its original context and finds that only when this bears a narrative relevance to the film does it cross from the diegetic to the nondiegetic plane. This reveals that whereas music restricted to the diegetic plane may express the outward projection of the characters' emotions, music also heard on the nondiegetic track may reveal a deeper truth about their feelings. In this way, the meaning of the music varies depending upon how it is used. While these two films may differ in whether or not their pre-existing music occupies a nondiegetic or diegetic position in relation to the narrative, both are characteristic of this era of British film-making in using music in an understated manner which expresses a sense of emotional restraint and which marks the films with a particularly British inflection.

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

RESUMENEl trabajo examina críticamente la afirmación central de la hermenéutica de Paul Ricoeur, a saber, que el soporte material de la escritura es el rasgo determinante para que una secuencia discursiva sea considerada como un texto. La escritura cancela las condiciones fácticas de la enunciación y crea, de este modo, un ámbito de sentido estable en el que se puede validar una concepción de la subjetividad que está implicada en las dos estrategias de lecturas (el análisis estructural y la apropiación), esto es, un sujeto pasivo que se constituye por la idealidad del significado. Asimismo, el trabajo intentará precisar una serie de ambigüedades en el uso que Ricoeur hace del «ser en el mundo» para sostener la referencialidad del discurso.PALABRAS CLAVETEXTO, ESCRITURA, REFERENCIA, SUBJETIVIDAD, MUNDOABSTRACTThis paper critically examines the main assertion of Paul Ricoeur´s hermeneutics, i.e., that the material base of writing is the determining feature to consider a discursive sequence as a text. Writing cancels the factual conditions of enunciation and creates, in this way, a background of stable meaning where it is possible to validate a conception of subjectivity implicated in the two reading strategies (the structural analysis and the appropriation), i.e., a passive subject constituted by the ideality of meaning. Likewise, this paper aims to clarify some ambiguities in the way Ricoeur uses the «beings in the world» to support the discourse referentiality.KEY WORDSTEXT, WRITING, REFERENCE, SUBJECTIVITY, WORLD

The Sri Lankan Ministry of National Coexistence, Dialogue, and Official Languages published the work “People of Sri Lanka” in 2017. In this comprehensive publication, 21 invited Sri Lankan scholars introduced 19 different people’s groups to public readers in English, mainly targeted at a growing number of foreign visitors in need of understanding the cultural diversity Sri Lanka has to offer. This paper will observe the presentation of these different groups of people, the role music and allied arts play in this context. Considering the non-scholarly design of the publication, a discussion of the role of music and allied arts has to be supplemented through additional analyses based on sources mentioned by the 21 participating scholars and their fragmented application of available knowledge. In result, this paper might help improve the way facts about groups of people, the way of grouping people, and the way of presenting these groupings are displayed to the world beyond South Asia. This fieldwork and literature guided investigation should also lead to suggestions for ethical principles in teaching and presenting of culturally different music practices within Sri Lanka, thus adding an example for other case studies.

The formation of comprehensive and in-depth notions of objects and phenomena in the world can be achieved when the mastery of knowledge and skills is carried out in a system realized in the context of integration of different scientific directions. One of the main issues in modern education is related to the contradiction - on one hand between the need to form the skills necessary for the orientation and adaptation of the personality in the dynamics of the globalizing world and on the other - the education which is largely based on unilateral acquiring of knowledge and skills within the different subject areas. This influences the development of a worldview and the formation of an adequate attitude towards the problems under consideration and the world as a whole. The knowledge and skills acquired today are often “locked” in the respective direction. The cross-curricular unity in the curriculum is of a recommended nature, but even if it is realized, it does not fully meet the need for a comprehensive and multifaceted consideration of global issues, as a result of which the student not only understands, reflects, but also applies the lessons learned in the process of creating a product - ideal or material. Combining the intellectual nature of the cognitive process with the practice activity are conditions in which the students are highly active and achieve better learning outcomes. Therefore, it is expedient for the different directions to correspond more closely to each other and to carry out effective cross-curricular integration. The concept of applying an integrative approach in the current paper is based on the idea of creating pedagogical conditions for reconciling the goals and expected outcomes of technology and entrepreneurship and natural sciences studied at the initial stage of the primary education. Integration can take place on two levels - knowledge and skills. We believe that the lapbook as an innovative didactic tool contains the necessary potential for effective realization of the educational goals in both directions in terms of achieving the expected results. In the course of its elaboration, new information is acquired in the field of engineering and technology, specific skills underlying the curricula of technology and entrepreneurship programs are developed. At the same time, a number of subjects from the learning content, which are considered from the natural science point of view, are enriched and perceived in a technological way, after which they find place in an attractive book - a lapbook, made by the students themselves. Its utilitarian value is multiplied by the personal contribution to its creation - not only as an object but also as content. The main topics that are of interest to the students are exploring and preserving nature, jobs, modern technical achievements, holidays and customs. As a result of the adequate integration of competences, tailored to curricula, a number of skills are formed, such as: skills for searching on their own, systematization and presentation of information, and application of the lessons learned in a new situation.

Ate appearances deceiving? Do objects behave the way they do becauseGod wills it? Ate objects impetmanent and do they only exist becausethey ate continuously created by God? According to a1 Ghazlli, theanswers to all of these questions ate yes. Objects that appear to bepermanent are not. Those relationships commonly tefemed to as causalare a result of God’s habits rather than because one event inevitably leadsto another. God creates everything in the universe continuously; if Heceased to create it, it would no longer exist.These ideas seem oddly naive and unscientific to people living in thetwentieth century. They seem at odds with the common conception of thephysical world. Common sense says that the universe is made of tealobjects that persist in time. Furthermore, the behavior of these objects isreasonable, logical, and predictable. The belief that the univetse is understandablevia logic and reason harkens back to Newton’s mechanical viewof the universe and has provided one of the basic underpinnings ofscience for centuries. Although most people believe that the world is accutatelydescribed by this sort of mechanical model, the appropriatenessof such a model has been called into question by recent scientificadvances, and in particular, by quantum theory. This theory implies thatthe physical world is actually very different from what a mechanicalmodel would predit.Quantum theory seeks to explain the nature of physical entities andthe way that they interact. It atose in the early part of the twentieth centuryin response to new scientific data that could not be incorporated successfullyinto the ptevailing mechanical view of the universe. Due largely ...
