Rocking behaviour of multi-block columns subjected to pulse-type ground motion accelerations

Ancient columns, made with a variety of materials such as marble, granite, stone or masonry are an important part of the
European cultural heritage. In particular columns of ancient temples in Greece and Sicily which support only the architrave are
characterized by small axial load values. This feature together with the slenderness typical of these structural members clearly
highlights as the evaluation of the rocking behaviour is a key aspect of their safety assessment and maintenance. It has to be noted
that the rocking response of rectangular cross-sectional columns modelled as monolithic rigid elements, has been widely investigated
since the first theoretical study carried out by Housner (1963). However, the assumption of monolithic member, although being
widely used and accepted for practical engineering applications, is not valid for more complex systems such as multi-block columns
made of stacked stone blocks, with or without mortar beds. In these cases, in fact, a correct analysis of the system should consider
rocking and sliding phenomena between the individual blocks of the structure. Due to the high non-linearity of the problem, the
evaluation of the dynamic behaviour of multi-block columns has been mostly studied in the literature using a numerical approach
such as the Discrete Element Method (DEM). This paper presents an introductory study about a proposed analytical-numerical
approach for analysing the rocking behaviour of multi-block columns subjected to a sine-pulse type ground motion. Based on the
approach proposed by Spanos (2001) for a system made of two rigid blocks, the Eulero-Lagrange method to obtain the motion
equations of the system is discussed and numerical applications are performed with case studies reported in the literature and with a
real acceleration record. The rocking response of single block and multi-block columns is compared and considerations are made
about the overturning conditions and on the effect of forcing function’s frequency.

Graphic design and modernisation in Greece, 1945-1970

The primary aim of this work is to give voice to the silent history of graphic design in Greece, long uncharted and undocumented in both the international forum and the local design community. This study focuses on the professional modernisation of graphic design and its role in providing the means for change in Greek society. The research is supported by interdisciplinary analysis of commercial advertisements, posters, leaflets and magazines, as well as other supporting documentation, in the historical and cultural context of Athens, Greece from 1945 to 1970. The time examined was a transitional and vociferous period in the history of Greece, one of intense and rapid economic modernisation during the post-Second World War decades from the mid-1940s to 1970. This was a time when, along with broader changes in the social, economic and political life of Greece, important developments in design education, print technology, and professional organisation marked a new age for graphic design, as a profession emerging from the broader ‘graphic arts’ field (inclusive of both technological and creative processes) and claiming autonomy over the more established fine arts sector. All four chapters deal with modernisation in relation to the assumed divisions of traditional/modern, continuity/change, centre/periphery. Main areas of investigation are: trade organisation, graphic design education, advertising and urbanisation, electricity and tourism promotion. This research offers a view of the ways the ‘modern’ and the condition of modernity were experienced in the case of Greece through certain applications of graphic design and its agents of influence: graphic designers, artists, managers, publishers, the state and private entrepreneurs. The research benefited significantly from a number of interviews with design professionals and related individuals. The present endeavour has a modest aim: to enable understanding of how and why Greek graphic design at the time came to be, and to stress the validity of the visual as a means of historical documentation.

Using Mobile Learning Games for Delivery Purposes in Humanities

Games and applications with gamified elements have been used in teaching and learning widely. Gamified applications attract the interest of students and teachers because they assist them to achieve their cognitive and pedagogical purposes. This paper describes a study that explores the use of a gamified learning application designed to introduce students at key stages 3 and 4 (ages 14-15) to ancient Greek Philosophy. The study involves 3 tests and 3 different groups of students and aimed to explore if the application improves students' knowledge and understanding and to compare different styles of subject delivering. This paper presents and discusses in details the results of the first test.

Evaluation of outpatient child-adolescent mental health services (CAMHS) in Attica-Greece

ABSTRACT: Background: Childhood is a critical time for social and emotional development, educational progress and mental health prevention. Mental health for children and adolescents is defined by the achievement of expected developmental, cognitive, social and emotional skills. The development of child-adolescent mental health services (CAMHS) is a necessity for each country, not only as a prevention measure for the wellbeing of people, but also as an investment to the future of countries. Qualitative evaluation of services is the only way to ensure whether services function under quality standards and increase the possibility of better outcomes for their patients. This study examines the greek outpatient CAMHS against the British Standards of National Institute of Excellence for community CAMHS. The Standards assessed refer to the areas of Assessment, Care and Intervention. Objectives: The main objectives of the study are 1) to evaluate Greek outpatient CAMHS in the Attica region 2) to promote the evaluation process for mental health services in Greece. Methods: Due to the fact that Greek services are based on the British model, the tool used was the British self-review questionnaire of Quality Network for Community CAMHS(QNCC).The tool was translated, adapted and posted to services. Twelve out of twenty outpatient CAMHS of Attica (including Athens) responded. Data was collected and performed by the Statistical Package for Social Sciences SPSS. Results: The study resulted that the CAMHS examined, meet moderately the British Standards of 1) Referral and Access, 2) Assessment & Care planning, 3) Care & Intervention. Two out of twelve services examined, meet the standards of "Assessment and Care" in a higher percentage between 75% and 100%. Conclusions: The paper describes a satisfactory function of CAMHS in Attica prefecture taking into consideration the extremely difficult political situation of Greece at the time of the research. Strong and weak domains are identified. Also the translation and adaptation of British tools promote the evaluation process and quality assurance of Greek CAMHS.

Heidegger's tragic Greeks : the relation between presence and deinon

Martin Heidegger's interpretation of the ancients was born out of something like a crisis in the interpretation of the Greeks, which can be characterized as nothing other than the realization of the idea that the Greek philosophers put a serious question mark over existence. This idea, which had its germination in Prussia with Jakob Burckhart and his teacher, but first came to be seriously cultivated in the Philosophy of Friedrich Nietzsche, was the first in depth investigation into whether the Greeks, on the one hand, questioned existence or, on the other hand, put a question mark over existence. To question existence is rather innocuous, since it amounts to little more, in the end, than a child looking up at the stars and asking what it all means. To put a question mark over existence, however, is another business entirely. For the Greeks, as the life work of Martin Heidegger amply demonstrates, the nature of Greek thinking and the objects towards which it is directed follows so absolutely from the tragic view of the human person that, in a certain sense, philosophy is Greek and could only have developed in Greece. Perhaps stating it a little less categorically, philosophy could have developed elsewhere at least to the extent that something like they way the Greeks understood life was at the forefront: presence, in other words. This thesis deals with the problem ofHeidegger's relation to the Greeks, specifically in terms of his understanding of the Greeks and presence. It is the position of this dissertation that the Greek notion of presence is, as Heidegger understands it, the homeliness of the hearth that radiates through all the things that humans concern themselves with. This is thought by Heidegger, as the Greeks did, specifically in contrast with the uncanninesslunhomeliness of the hqrnan apart from his or her concern with things. Therefore, the thesis is an attempt at exposing the relation between presence and the unhomely by situating it withing Greek existence and the meaning of the Greek Philosopher. In order to support this position, the thesis has been divided into five parts. The first two chapters deal with Heidegger's explanation of the relation between Greek notion of physics (Phusis), metaphysics (specifically in relation to an analysis of time and motion in Greek thought), and what Heidegger calls the fundamental attunement of Dasein (boredom). More exactly, it deals with these issues only so far as they allow us to bring out something like the notion of 'presence' in relation to things and homelessness or restlessness in relation to the human being. The rationale for these two chapters in relation to the central problem of the paper is that in Heidegger's elucidation of physics and metaphysics, he conducts his analysis in such a way that he explicitly uncovers that dimension of human existence that he calls the fundamental attunement of Dasein. This fundamental attunement is, in tum, similar to what the Greeks understood as the deinon, the uncanninesslunhomeliness of the human. The third and fourth chapters take as their explicit themes the problem of the Greek understanding of the assertion and the ways in which the person can comport himlherself toward things, two issues which are not separable. The rationale for these two chapters in relation to the central theme of the paper is that Heidegger's analysis of these two areas in Greek thought brings out precisely why the philosopher and the philosophical way of life is the highest mode of existence for the Greeks and how this is thought specifically in tenns of the uncanniness of humans. The final cijapter gives a complete elucidation of presence as the homeliness of the hearth and shows specifically how this is thought of in contradistinction to the uncanny/unhomely for the Greeks. 1I1 This last chapter also explains Martin Heidegger's reaction to the Greek's interpretation of the highest mode of existence, and what he posited as a counter-thought. The essay as a whole is an attempt to fully concertize an important dimension of Heidegger' s understanding of the Greeks, that is, the relation between presence and the deinon or Greek notion ofunhomely, which, to my la)owledge, has not been offered anywhere in commentaries on Heidegger.
