Exploring classical Greek construction problems with interactive geometry software
Meskens, Ad
2017-01-01
In this book the classical Greek construction problems are explored in a didactical, enquiry based fashion using Interactive Geometry Software. The book traces the history of these problems, stating them in modern terminology. By focusing on constructions and the use of GeoGebra the reader is confronted with the same problems that ancient mathematicians once faced. The reader can step into the footsteps of Euclid, Viète and Cusanus amongst others and then by experimenting and discovering geometric relationships far exceed their accomplishments. Exploring these problems with the neusis-method lets him discover a class of interesting curves. By experimenting he will gain a deeper understanding of how mathematics is created. More than 100 exercises guide him through methods which were developed to try and solve the problems. The exercises are at the level of undergraduate students and only require knowledge of elementary Euclidean geometry and pre-calculus algebra. It is especially well-suited for those student...

The book is an innovative modern exposition of geometry, or rather, of geometries; it is the first textbook in which Felix Klein's Erlangen Program (the action of transformation groups) is systematically used as the basis for defining various geometries. The course of study presented is dedicated to the proposition that all geometries are created equal--although some, of course, remain more equal than others. The author concentrates on several of the more distinguished and beautiful ones, which include what he terms "toy geometries", the geometries of Platonic bodies, discrete geometries, and classical continuous geometries. The text is based on first-year semester course lectures delivered at the Independent University of Moscow in 2003 and 2006. It is by no means a formal algebraic or analytic treatment of geometric topics, but rather, a highly visual exposition containing upwards of 200 illustrations. The reader is expected to possess a familiarity with elementary Euclidean geometry, albeit those lacking t...

This book provides a systematic introduction to various geometries, including Euclidean, affine, projective, spherical, and hyperbolic geometries. Also included is a chapter on infinite-dimensional generalizations of Euclidean and affine geometries. A uniform approach to different geometries, based on Klein's Erlangen Program is suggested, and similarities of various phenomena in all geometries are traced. An important notion of duality of geometric objects is highlighted throughout the book. The authors also include a detailed presentation of the theory of conics and quadrics, including the theory of conics for non-Euclidean geometries. The book contains many beautiful geometric facts and has plenty of problems, most of them with solutions, which nicely supplement the main text. With more than 150 figures illustrating the arguments, the book can be recommended as a textbook for undergraduate and graduate-level courses in geometry.

Astronomy as a science began with the Ionian philosophers, with whom Greek philosophy and mathematics also began. While the Egyptians and Babylonians had accomplished much of astronomical worth, it remained for the unrivalled speculative genius of the Greeks, in particular, their mathematical genius, to lay the foundations of the true science of astronomy. In this classic study, a noted scholar discusses in lucid detail the specific advances made by the Greeks, many of whose ideas anticipated the discoveries of modern astronomy.Pythagoras, born at Samos about 572 B.C., was probably the first

Spinning geometry = Twisted geometry
International Nuclear Information System (INIS)
Freidel, Laurent; Ziprick, Jonathan
2014-01-01
It is well known that the SU(2)-gauge invariant phase space of loop gravity can be represented in terms of twisted geometries. These are piecewise-linear-flat geometries obtained by gluing together polyhedra, but the resulting geometries are not continuous across the faces. Here we show that this phase space can also be represented by continuous, piecewise-flat three-geometries called spinning geometries. These are composed of metric-flat three-cells glued together consistently. The geometry of each cell and the manner in which they are glued is compatible with the choice of fluxes and holonomies. We first remark that the fluxes provide each edge with an angular momentum. By studying the piecewise-flat geometries which minimize edge lengths, we show that these angular momenta can be literally interpreted as the spin of the edges: the geometries of all edges are necessarily helices. We also show that the compatibility of the gluing maps with the holonomy data results in the same conclusion. This shows that a spinning geometry represents a way to glue together the three-cells of a twisted geometry to form a continuous geometry which represents a point in the loop gravity phase space.

Greek festival calendars were in origin lunar, eventually being aligned with the sun through various lunisolar intercalary cycles. Each city-state had its own calendar, whose month names have some, little, or no similarity with those of other city-states. These names often reflect gods or festivals held in their honor in a given month, so there is an explicitly sacred character to the calendar. New Year's Day could also differ from one state to another, but generally began with the sighting of the first new moon after one of the four tropical points. Even the introduction of the Roman Julian calendar brought little uniformity to the eastern Greek calendars. The calendar is one of the elements which can assist in understanding the siting of Greek sacred structures.

The 3rd edition of this year's Greek Teachers Programme was co-organized by CERN Education Group and the Hellenic Physical Society and took place from 8 to 12 November 2015. The programme targets physics high-school teachers from all over Greece. It aims to help teachers inspire the next generation of scientists and engineers by motivating their students to understand and appreciate how science works at the world's largest physics laboratory, whereby increasing their interest in pursuing studies in STEM fields in secondary and post-secondary education. 33 teachers took part in this programme which comprised lectures by Greek members of the CERN scientific community, with visits to experimental facilities, hands-on activities and dedicated sessions on effective and creative ways through which participants may bring physics, particle physics and CERN closer to their school classroom. In 2015, more than 100 teachers took part in the three editions of the Greek Teachers Programme.

Reconsiderations about Greek homosexualities.
Percy, William Armstrong
2005-01-01
Focusing his analysis on (mostly Athenian) vase paintings of the sixth- and early fifth-century and on a handful of texts from the late fifth- and early fourth-century (again Athenian), Dover depicted the pederastic relationship of erastes (age 20 to 30) and eromenos (age 12-18) as defined by sexual roles, active and passive, respectively. This dichotomy he connected to other sexual and social phenomena, in which the active/ penetrating role was considered proper for a male adult Athenian citizen, while the passive/penetrated role was denigrated, ridiculed, and even punished. Constructing various social and psychological theories, Foucault and Halperin, along with a host of others, have extended his analysis, but at the core has remained the Dover dogma of sexual-role dichotomization. Penetration has become such a focal point in the scholarship that anything unable to be analyzed in terms of domination is downplayed or ignored. To reduce homosexuality or same-sex behaviors to the purely physical or sexual does an injustice to the complex phenomena of the Greek male experience. From Sparta to Athens to Thebes and beyond, the Greek world incorporated pederasty into their educational systems. Pederasty became a way to lead a boy into manhood and full participation in the polis, which meant not just participation in politics but primarily the ability to benefit the city in a wide range of potential ways. Thus the education, training, and even inspiration provided in the pederastic relationship released creative forces that led to what has been called the Greek 'miracle.' From around 630 BCE we find the institution of Greek pederasty informing the art and literature to a degree yet to be fully appreciated. Moreover, this influence not only extends to the 'higher' realms of culture, but also can be seen stimulating society at all levels, from the military to athletic games, from philosophy to historiography. An understanding of sexual practices-useful, even essential, to

Morphological Variation in the Imperfect of hewâ in Onqelos and Jonathan
Directory of Open Access Journals (Sweden)
Jerome A. Lund
2018-06-01
Full Text Available Two morphological types of the imperfect of the verb hewâ appear in Onqelos and Jonathan, namely yihwê and yehê. While the two types distinguish gender in the plural, they do not do so in the singular. Statistically, the waw type is marginal in the second and third persons singular, but well attested in the first person singular. The use of the waw type in the singular appears to be conditioned by stylistic considerations, being employed to give the impression of solemnity. It is suggested that the waw type reflects the language of the proto-targum from which it was retained.

The smooth functioning of an ordered society depends on the possession of a means of regularising its activities over time. That means is a calendar, and its regularity is a function of how well it models the more or less regular movements of the celestial bodies - of the moon, the sun or the stars. Greek and Roman Calendars examines the ancient calendar as just such a time-piece, whose elements are readily described in astronomical and mathematical terms. The story of these calendars is one of a continuous struggle to maintain a correspondence with the regularity of the seasons and the sun, d

Nasalance norms in Greek adults.
Okalidou, Areti; Karathanasi, Asimina; Grigoraki, Eleni
2011-08-01
The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.
Feyz Kashani and Jonathan Edwards on the Place of Heart in Religious Knowledge
Directory of Open Access Journals (Sweden)
Saham Asadinia
2014-08-01
Full Text Available This essay seeks to summarize and compare the theological ideas of Jonathan Edwards, a western philosopher, with those of Feyz Kashani, an eastern philosopher. The reason for this study is the numerous conjunctions that are seen in their ideas. These include the harmony of heart and reason in respect to belief, the priority of the heart in the reflection of truth, the belief in centrality of the religion of heart, the necessity of divine grace in the flow of religious knowledge, the emphasis on the esoteric side of religion as opposed to the exoteric side, and the importance of a practical approach to religion. Significant differences also exist between their ideas. For instance, Edwards believes that human nature is sinful and corrupted while Feyz does not believe this is true. Furthermore, Feyz interprets the path of heart to be based on reason, while Edwards has a different point of view.

Greeks, British Greek Cypriots and Londoners: a comparison of morbidity.
Mavreas, V G; Bebbington, P E
1988-05-01
This paper reports the results of a comparison of the rates of psychiatric disorder from three general population surveys in which the PSE-ID-CATEGO system was used for case-definition. These surveys were of an English sample in Camberwell, London, and of two Greek samples, the first in Athens, the second of Greek Cypriot immigrants living in Camberwell. The results show that the rates of psychiatric disorders in both Greek samples were somewhat higher than those of the Camberwell population, the differences being accounted for by higher rates of anxiety disorders, especially in women. Comparisons in terms of syndrome profiles showed that Greeks reported more symptoms of generalized anxiety than their English counterparts who, in their turn, reported higher rates of obsessive symptoms, and symptoms of social anxiety. The higher rates in the Greek samples were possibly due to an increased frequency of non-specific neurotic symptoms like worrying and tension. The results of other European community surveys with the PSE suggest that there might be a genuine and general North-South difference in the expression of psychological distress. Cultural differences in terms of personality traits and culturally sanctioned child rearing practices might account for the findings.

Full Text Available The present paper examines the issue of the Greek public debt. After providing a historical discussion, we show that the austerity of the last six years has been unsuccessful in stabilizing the debt while, at the same time, it has taken a heavy toll on the economy and society. The recent experience shows that the public debt is unsustainable and therefore a restructuring is needed. An insistence on the current policies is not justifiable either on pragmatic or on moral or any other grounds. The experience of Germany in the early post-WWII period provides some useful hints for the way forward. A solution to the public debt problem is a necessary but not sufficient condition for the solution of the Greek and European crisis. A wider agenda that deals with the malaises of the Greek economy and the structural imbalances of the Eurozone is of vital importance.

Dreams in ancient Greek Medicine.

2016-01-01
Dreams preoccupied the Greek and Roman world in antiquity, therefore they had a prominent role in social, philosophical, religious, historical and political life of those times. They were considered as omens and prophetic signs of future events in private and public life, and that was particularly accentuated when elements of actions which took place in the plot of dreams were associated directly or indirectly with real events. This is why it was important to use them in divination, and helped the growth of superstition and folklore believes. Medicine as a science and an anthropocentric art, could not ignore the importance of dreams, having in mind their popularity in antiquity. In ancient Greek medicine dreams can be divided into two basic categories. In the first one -which is related to religious medicine-dreams experienced by religionists are classified, when resorted to great religious sanctuaries such as those of Asclepius (Asclepieia) and Amphiaraos (Amfiaraeia). These dreams were the essential element for healing in this form of religious medicine, because after pilgrims underwent purifications they went to sleep in a special dwelling of the sanctuaries called "enkoimeterion" (Greek: the place to sleep) so that the healing god would come to their dreams either to cure them or to suggest treatment. In ancient Greek literature there are many reports of these experiences, but if there may be phenomena of self-suggestion, or they could be characterized as propaganda messages from the priesthood of each sanctuary for advertising purposes. The other category concerns the references about dreams found in ancient Greek medical literature, where one can find the attempts of ancient Greek physicians to interpret these dreams in a rational way as sings either of a corporal disease or of psychological distress. This second category will be the object of our study. Despite the different ways followed by each ancient Greek physician in order to explain dreams, their

250 years ago, the satirical writer and clergyman Jonathan Swift from Dublin (1667-1745) founded the first Irish lunatic asylum. Rejecting the theories put forward by the English philosopher Thomas Hobbes and the doctor Thomas Willis, he was influenced by the ideas of the Scottish doctor and the "enlightened" thinker John Locke. Swift's St. Patrick's Hospital did not, however, realise a new philosophical concept: architecture and therapeutic approach of the new institution were clearly modelled on the much older Hospital of St. Mary of Bethlehem ( = Bedlam). Despite its conservative conceptual basis, the first institution dedicated to the mentally ill and intellectually subnormal in Ireland became a starting point for the apparantly unstoppable expansion of the, at one time, most comprehensive asylum system in the world. After Swift's Hospital had been enlarged twice at the tax-payers' expense (1778, 1793), the administration decided to relieve the institution by erecting the Richmond Asylum (1810), the first public asylum in Ireland. When this establishment also became overcrowded, in 1817, legislation was passed which led to the establishment of the oldest system of public asylums in Europe.

2017-12-01
The Genetics Society of America's Edward Novitski Prize recognizes a single experimental accomplishment or a body of work in which an exceptional level of creativity and intellectual ingenuity has been used to design and execute scientific experiments to solve a difficult problem in genetics. The 2017 winner, Jonathan Hodgkin, used elegant genetic studies to unravel the sex determination pathway in Caenorhabditis elegans He inferred the order of genes in the pathway and their modes of regulation using epistasis analyses-a powerful tool that was quickly adopted by other researchers. He expanded the number and use of informational suppressor mutants in C. elegans that are able to act on many genes. He also introduced the use of collections of wild C. elegans to study naturally occurring genetic variation, paving the way for SNP mapping and QTL analysis, as well as studies of hybrid incompatibilities between worm species. His current work focuses on nematode-bacterial interactions and innate immunity. Copyright © 2017 by the Genetics Society of America.

Full Text Available The article is devoted to the study of grotesque forms in Jonathan Swift's novel "Gulliver’s Travels" based on the text of part II of the novel "A Voyage to Brobdingnag". On the basis of the selected actual material, displays of the grotesque elements in the semantic field of the work’s text are traced. The grotesque world of the novel is the author's model of mankind, in which J. Swift presents his view not only on the state of the modern system of England, but also on the nature of man in general, reveals the peculiarities of the psychology of human nature, especially human socialization. In part II, the author continues to develop a complex and contradictory picture of human existence in front of the reader, the world of giants appears as an ambivalent system in which the features of an ideal society and ideal ruler, in author’s opinion, with the ugly face of man and society, are marvelously combined.

The geometry of classical physics is Lorentzian; but weaker geometries are often more appropriate: null geodesics and electromagnetic fields, for example, are well known to be objects of conformal geometry. To deal with a single null congruence, or with the radiative electromagnetic fields associated with it, even less is needed: flag geometry for the first, optical geometry, with which this paper is chiefly concerned, for the second. The authors establish a natural one-to-one correspondence between optical geometries, considered locally, and three-dimensional Cauchy-Riemann structures. A number of Lorentzian geometries are shown to be equivalent from the optical point of view. For example the Goedel universe, the Taub-NUT metric and Hauser's twisting null solution have an optical geometry isomorphic to the one underlying the Robinson congruence in Minkowski space. The authors present general results on the problem of lifting a CR structure to a Lorentz manifold and, in particular, to Minkowski space; and exhibit the relevance of the deviation form to this problem

Full Text Available The article deals with the history of contacts and cultural exchange between the Jews and the Greeks in early and late antiquity, especially relevant not only for historians and philologists, but also for those interested in Hellenistic philosophy and the origins of Christianity, having its roots into a very complex fusion of Jewish and Greek tradition. Metropolitan city of Alexandria in Ptolemaic Egypt provided a very fruitfull milieu for this kind of cultural contact just from the time the group of seventy-two translators arrived to the city to translate the Hebrew Scripture for the famous library in the time of Ptolemy II (285-247 BCE and his librarian Demetrius of Phalerum. For the genealogy of contacts between two nations that both contributed so much to the Western thought, we may, of course, go back to the history and relevant sources. The City of Jerusalem, for instance, is mentioned for the first time in the old Egyptian Tell el-Amarna correspondence (XIV. century BCE, while the Jews (though often named as the Syrians of Palestine are referred to by many Greek authors (poet Alcaius from Lesbos, Herodotus, Theophrastus, Hecataeus of Abdera, an Egyptian priest in Heliopolis Manetho, Polybius, Menander, and many others. The Hebrew Bible (Tanakh on the other hand, provides an interesting source of records of contacts between the old Israelites and the Greek speaking tribes (from the Ionian isles, Crete, Cyprus etc, back to the reign of king David and king Solomon (X. century BCE, which both allegedly enrolled Greek soldiers and officials in their armies (cf. 2 Samuel 20, 23; 1 Kings 1, 38. The Bible also reports about trade contacts between Palestine and Greek lsles (cf. Ezekiel 27, 7; Joel 4.6, and also about Greek settlers in the 'Holly land' (cf. Deuteronomy 2, 23; Jeremiah 47, 4; Zephaniah 2, 5. The period after Alexander the Great is also very important for relations between Greeks and Jews. When his diadochoi came to Palestine, they

Around 2005 it became apparent in the geometry processing community that freeform architecture contains many problems of a geometric nature to be solved, and many opportunities for optimization which however require geometric understanding. This area of research, which has been called architectural geometry, meanwhile contains a great wealth of individual contributions which are relevant in various fields. For mathematicians, the relation to discrete differential geometry is significant, in particular the integrable system viewpoint. Besides, new application contexts have become available for quite some old-established concepts. Regarding graphics and geometry processing, architectural geometry yields interesting new questions but also new objects, e.g. replacing meshes by other combinatorial arrangements. Numerical optimization plays a major role but in itself would be powerless without geometric understanding. Summing up, architectural geometry has become a rewarding field of study. We here survey the main directions which have been pursued, we show real projects where geometric considerations have played a role, and we outline open problems which we think are significant for the future development of both theory and practice of architectural geometry.

The book provides a comprehensive introduction and a novel mathematical foundation of the field of information geometry with complete proofs and detailed background material on measure theory, Riemannian geometry and Banach space theory. Parametrised measure models are defined as fundamental geometric objects, which can be both finite or infinite dimensional. Based on these models, canonical tensor fields are introduced and further studied, including the Fisher metric and the Amari-Chentsov tensor, and embeddings of statistical manifolds are investigated. This novel foundation then leads to application highlights, such as generalizations and extensions of the classical uniqueness result of Chentsov or the Cramér-Rao inequality. Additionally, several new application fields of information geometry are highlighted, for instance hierarchical and graphical models, complexity theory, population genetics, or Markov Chain Monte Carlo. The book will be of interest to mathematicians who are interested in geometry, inf...

Full Text Available The salpinx is not often treated by scholars of ancient Greek music, because it was mainly a military instrument. The instrument was usually not used for musical purposes, only for giving signals. In Greece the salpinx is known from the 8th century onwards. The Greek salpinx was an aerophone, usually made of bronze, and consisted of an 80 to 120 cm long, straight, tube with cylindrical bore, and with a conical or more often bell-shaped final, kodon, which could be made of bone. The bone had to be fired in order to get the right acoustic qualities, according to Aristotle. Salpinx is usually translated as "trumpet", but the type of sound generator it may have had has been discussed.
Showroom10: Greek designers showroom
Evgeneiadou, E.
2017-10-01
Showroom10 is the first exclusive Greek designer’s showroom. It represents established and upcoming Greek designers in Greece and Cyprus. The mission and main task is to successfully place the designer’s collections in the Greek, European and worldwide market. The purpose of the showroom is to put a collection in front of the appropriate buyer accelerate its revenue growth and create brand awareness. The search for new collections is one of the most important tasks and challenge of a showroom’s business. Market research, travels and fashion trade shows are some ways to stand before an interested brand. Each collection must first be selected in terms of authenticity, clear brand DNA as we call it in fashion. Secondly, must be competitive in terms of materials, designs and prices. But, are all the above enough for the global fashion market? This paper describes a case study (Showroom 10), showing a general overview about the most important phases of “designer’s road” in Greece.

Because of history, culture, and politics, European identity has its archetypical elements in ancient Greek culture. Ancient Greek philosophy brought Logos to fore and defined it as the crucial problem and the postulate of the human. We translate the Greek term Logos in English as reason or rationality. These terms, however, do not cover the semantic field of Logos since this includes, among other things, order of being, ground, language, argument etc. The juxtaposition of Logos (reason) to m...

Each culture recognizes and identifies death, dying and bereavement in unique ways. Commonly, a culture may be seen through the lens of death rituals; how those are shaped, interpreted and used by the society. This paper aims to look at the Modern Greek culture and depict its ‘visualization’ of death, as well as capture the rituals that mostly identify this specific culture. The Greek culture in overall is strongly influenced by the Greek Orthodox Church. Hence, the experiences of death, dyin...

Intended for a one year course, this text serves as a single source, introducing readers to the important techniques and theorems, while also containing enough background on advanced topics to appeal to those students wishing to specialize in Riemannian geometry. This is one of the few Works to combine both the geometric parts of Riemannian geometry and the analytic aspects of the theory. The book will appeal to a readership that have a basic knowledge of standard manifold theory, including tensors, forms, and Lie groups. Important revisions to the third edition include: a substantial addition of unique and enriching exercises scattered throughout the text; inclusion of an increased number of coordinate calculations of connection and curvature; addition of general formulas for curvature on Lie Groups and submersions; integration of variational calculus into the text allowing for an early treatment of the Sphere theorem using a proof by Berger; incorporation of several recent results about manifolds with posit...

A special manifold is an allowed target manifold for the vector multiplets of D=4, N=2 supergravity. These manifolds are of interest for string theory because the moduli spaces of Calabi-Yau threefolds and c=9, (2,2) conformal field theories are special. Previous work has given a local, coordinate-dependent characterization of special geometry. A global description of special geometries is given herein, and their properties are studied. A special manifold M of complex dimension n is characterized by the existence of a holomorphic Sp(2n+2,R)xGL(1,C) vector bundle over M with a nowhere-vanishing holomorphic section Ω. The Kaehler potential on M is the logarithm of the Sp(2n+2,R) invariant norm of Ω. (orig.)

Full Text Available Learning Greek as a second or foreign language has drawn the attention of many researchers throughout time. A dictionary is amongst the first things a foreign language student uses. Reading comprehension is significantly improved by the use of a dictionary, especially when this includes the way words are pronounced. We developed a assistance software for learning the Greek Language via Greeklish. Since, the basic vocabulary of a language is the basis of understanding the language itself, the dictionary proposed aims to make the basic Greek words easier to pronounce as well as to give the explanation of the word in English. The aim of this software is to provide a useful tool to learn the Greek language individually. Moreover, it aims to be involved, as an assistance tool for learning Greek as a second or foreign language.

Full Text Available In textual criticism it is important to detect the genesis of mistakes; sometimes the true reading is only reached through the unmasking of the wrong one. Likewise, in order to use critically the Septuagint it is indispensable to find out first its corruptions and mistranslations. The making of a Greek-Hebrew Index of the Antiochene Text in the Historical Books is an excellent occasion to observe the translation process and find out the most common errors made by the translators. A few examples will be commented concerning the following issues: inner-Greek corruptions and misleading translations caused by the graphic confusion of similar letters (paleography or sounds (phonetics, and by a different reading or vocalization of the consonantal text. In several cases this analysis may open a window towards a non-Masoretic Hebrew Vorlage.

De igual manera, para usar críticamente la Septuaginta es imprescindible descubrir primero las corrupciones y los errores de traducción. La confección de un índice griego-hebreo del texto antioqueno en los libros históricos es una ocasión excelente para analizar el proceso de traducción y detectar los errores más comunes cometidos por los traductores. En el artículo se estudian algunos ejemplos con relación a los siguientes fenómenos: corrupciones internas al griego y traducciones equivocadas motivadas por la confusión gráfica de letras (paleografía o sonidos (fonética semejantes y por una vocalización diferente del texto consonántico. En varios casos este análisis permite vislumbrar un texto base hebreo distinto del masorético.

Greek, Indian and Arabic Logic marks the initial appearance of the multi-volume Handbook of the History of Logic. Additional volumes will be published when ready, rather than in strict chronological order. Soon to appear are The Rise of Modern Logic: From Leibniz to Frege. Also in preparation are Logic From Russell to Gödel, Logic and the Modalities in the Twentieth Century, and The Many-Valued and Non-Monotonic Turn in Logic. Further volumes will follow, including Mediaeval and Renaissance Logic and Logic: A History of its Central. In designing the Handbook of the History of Logic, the Editors have taken the view that the history of logic holds more than an antiquarian interest, and that a knowledge of logic's rich and sophisticated development is, in various respects, relevant to the research programmes of the present day. Ancient logic is no exception. The present volume attests to the distant origins of some of modern logic's most important features, such as can be found in the claim by the authors of t...
5000 years of geometry mathematics in history and culture
Scriba, Christoph J
2015-01-01
The present volume provides a fascinating overview of geometrical ideas and perceptions from the earliest cultures to the mathematical and artistic concepts of the 20th century. It is the English translation of the 3rd edition of the well-received German book “5000 Jahre Geometrie,” in which geometry is presented as a chain of developments in cultural history and their interaction with architecture, the visual arts, philosophy, science, and engineering. Geometry originated in the ancient cultures along the Indus and Nile Rivers and in Mesopotamia, experiencing its first “Golden Age” in Ancient Greece. Inspired by the Greek mathematics, a new germ of geometry blossomed in the Islamic civilizations. Through the Oriental influence on Spain, this knowledge later spread to Western Europe. Here, as part of the medieval Quadrivium, the understanding of geometry was deepened, leading to a revival during the Renaissance. Together with parallel achievements in India, China, Japan and the ancient American cultur...

2008-02-01
The college years offer an opportunity for new experiences, personal freedom, and identity development; however, this period is also noted for the emergence of risky health behaviors that place college students at risk for health problems. Affiliation with on-campus organizations such as fraternities or sororities may increase a students' risk given the rituals and socially endorsed behaviors associated with Greek organizations. In this study, we examined alcohol and drug use, smoking, sexual behavior, eating, physical activity, and sleeping in 1,595 college students (n = 265 Greek members, n = 1,330 non-Greek members). Results show Greek members engaged in more risky health behaviors (e.g., alcohol use, cigarette smoking, sexual partners, and sex under the influence of alcohol or drugs) than non-Greek members. Greek and non-Greek members did not differ in condom use, unprotected sex, eating, and physical activity behaviors. Implications for prevention and intervention strategies among Greek members are discussed.
The language of modern medicine: it's all Greek to me.

The Greek language has shaped and formed the lexicon of modern medicine. Although medical terminology may seem complex and difficult to master, the clarity and functionality of this language owe a great debt to the tongue of the classical Greeks.

Greek women and broken nerves in Montreal.
Dunk, P
1989-05-01
In this paper, I examine the importance of class, ethnicity and gender in the causation and meaning of somatization for Greek women in Montreal. I argue that nevra--a form of psychosocial distress experienced by many of the women--is a phenomenon of the poor working conditions, low wages and gender relations in the Greek community. Data is based on interviews with 100 Greek families in Montreal and 45 patients in two different clinical settings. Comparing results with material on nervios and nerves from Latin America and the United States, I concur with Low (1985) that nerves should be viewed as a 'culturally-interpreted symptom' rather than a 'culture bound syndrome'. It is further suggested that the importance of social and material conditions and gender relations in mediating the cultural interpretation must be stressed. Failure to do so often results in the medicalization of nevra and the creation of a chronic sick role for the patient.
Preprocessing Greek Papyri for Linguistic Annotation

Vierros, Marja
2017-08-01
Full Text Available Greek documentary papyri form an important direct source for Ancient Greek. It has been exploited surprisingly little in Greek linguistics due to a lack of good tools for searching linguistic structures. This article presents a new tool and digital platform, “Sematia”, which enables transforming the digital texts available in TEI EpiDoc XML format to a format which can be morphologically and syntactically annotated (treebanked, and where the user can add new metadata concerning the text type, writer and handwriting of each act of writing. An important aspect in this process is to take into account the original surviving writing vs. the standardization of language and supplements made by the editors. This is performed by creating two different layers of the same text. The platform is in its early development phase. Ongoing and future developments, such as tagging linguistic variation phenomena as well as queries performed within Sematia, are discussed at the end of the article.
Apolipoprotein E polymorphism in the Greek population.
Sklavounou, E; Economou-Petersen, E; Karadima, G; Panas, M; Avramopoulos, D; Varsou, A; Vassilopoulos, D; Petersen, M B
1997-10-01
The APOE gene is located on chromosome 19, and the three common alleles are designated epsilon2, epsilon3, and epsilon4. The epsilon4 allele is associated with increased plasma cholesterol, atherosclerosis and cardiovascular disease, Alzheimer's disease, and decreased longevity. The objective of the present study was to estimate the distribution of APOE alleles in the Greek population by DNA analysis. The material consisted of 216 voluntary, healthy Greek blood donors (146 males/70 females). The APOE allele frequencies were epsilon2: 5.3%, epsilon3: 88.2%, epsilon4: 6.5%. The epsilon4 allele frequency of 6.5% in the Greek population is, together with the frequency in the Chinese population, among the lowest in the world.

A Greek physician's portrait in Windsor Castle.

To the visitor to Windsor Castle, the Thomas Lawrence portraits in the Waterloo Chamber represent the most important contributors to the military defeat of Napoleon Bonaparte, by British, Prussian, Russian and Austrian forces at the Battle of Waterloo. Nevertheless, only few individuals realise that a Greek physician, Count Ioannis Capodistrias, a native of the island of Corfu, stands among these leading personalities as a diplomat, the Russian Minister of Foreign Affairs, who contributed remarkably to European unity in the early nineteenth century and as a statesman ('Governor' of Greece) with a tragic end to his life, after establishing a Greek State practically from ruins.
Making a Voluntary Greek Debt Exchange Work

The Greek Financial Crisis – Theoretical Implications
Directory of Open Access Journals (Sweden)
Garry Jacobs
2015-10-01
Full Text Available The world we live in is a product of the way we think. Our conception of reality determines what we see and what we achieve. The Greek crisis is not simply a case of high public debt, economic mismanagement or weak political will in Greece or the Eurozone. It is underpinned by economic premises, constructs and resulting practices that promote exactly the type of dilemma Greece faces today. Without addressing these conceptual issues, no lasting solution is possible. Rather it can be expected to repeat and spread to other countries and regions. This article is based on views presented by participants in a WAAS webinar examining the Greek financial crisis in the light of economic theory and practice. Wherever there are unmet social needs and underutilized social resources, such as high levels of unemployment, the potential exists to stimulate economic activity, enhance human welfare and promote resilience and sustainable entrepreneurship. Both conditions prevail in Greece today, but neither current nor anticipated policies are likely to result in near term benefits to the Greek people and the local economy nor for Europe and the world economy. It supports the view that a permanent and effective win-win solution can be found to the Greek crisis, compatible with the financial stability of the country and the welfare of its citizens within the framework of the Eurozone, but that such a solution will require a rethinking of fundamental theoretical issues and adoption of innovative policy instruments beyond those presently being contemplated.

The Greek outside workers radiation passbook

Kamenopoulou, V.
1997-01-01
Following the European Council Directive 90/641/EURATOM of the 4 December 1990, on the operational protection of outside workers exposed to the risk of ionising radiation during their activities in controlled areas, the Greek Government has adopted the Ministerial Order, published in the Official Gazette (No 9087(FOR) 1004 of 1996). The Greek Atomic Energy Commission (GAEC) is the competent governmental authority for radiation protection matters. Therefore it is the GAEC's responsibility of monitoring the implementation of this Order. The Order consists of 6 parts, where among others are described the obligations of outside undertakings and operators and the obligations of outside workers. One of the major elements of this Ministerial Order is the radiation passbook.The Greek Radiation Passbook is written in two languages, Greek and English. It contains worker's personal data (identity, medical examinations, training in radiation protection, etc), information concerning his employee (name, address, etc) and worker's dosimetry information such as operational and the official dosimetry (external and internal) data. The radiation passbook is provided only to category A outside workers, working in Greece or abroad. The GAEC distributed the Ministerial Order with application forms to the possible outside undertakings for their information. Until August 1997, 41 radiation passbooks have been attributed to outride workers. All of them are technicians dealing with medical equipment using ionizing radiation. (author)

Truth Obviousness in Ancient Greek Philosophy
Directory of Open Access Journals (Sweden)
Halyna I. Budz
2013-01-01
Full Text Available The article examines the features of the axiomatic approach to the truth understanding in ancient Greek philosophy. Truth in the works by ancient philosophers has axiomatic essence, basing on divine origin of truth. As the truth has a divine origin, it is in reality. The reality, created by Gods is the solemn reality. Therefore, understanding of reality by man is the display of divine reality, which is true and clever. In of the context of ancient Greek philosophy, to know truth is to know something, existing in reality, in other words, something, truly existing, eternal reality. Consequently, to know truth is it to know the substantial reality base. That’s why the justification of the reality origin is the axiomatic doctrine of truth at the same time, because only fundamental principle “truly” exists and is the truth itself. The idea of fundamental principle in ancient Greek philosophy is the axiom, universal principle, which is the base of reality as a substance from ontological perspective and is realized as the truth from gnosiological perspective. Fundamental principle, as Greeks understand it, coincides with the truth, in other words, reality and thinking are identical. The idea of reality source is the universal criterion of world perception at the same time, in other words, it is the truth, which is perceived axiomatically.

The Greek media and the Kosovo crisis

Margarita Kondopoulou
2002-10-01
Full Text Available The NATO air attacks (24/3/99-10/6/99 as an instrument of force against Serbia to terminate the abuse of the Albanian population in Kosovo, albeit supported by a significant part of the international community, were received much differently in Greece. Key to the climate of strong disagreement with the campaign was the role of the Greek media. The true reason behind the offensive was, according to them, the change in the geopolitical map to the advantage of the West, and in particular the USA. The underlying argument of this paper is that in the Kosovo crisis the media, Greek (and international, projected their own environment. It is particularly apt to examine the Greek case because of its very unique perspective that differentiated the coverage in Greece - a NATO member country - from the overall world media view. Also, the discussion is pertinent because Greek media coverage disagreed with the official government position, which although advocating a diplomatic resolution of the crisis, had to support the Alliance's decision to bomb Serbia. Furthermore, study of this case is significant because the clash of the Greek media view with the mainstream pro-NATO coverage found in many other countries generated negative views on Greece and its media on the international level. An examination of media content reveals that despite any differences concerning political or other factors, and regardless of the variations in the phrasing of the anti-NATO arguments, the overall media perspective exhibited a unanimous opposition to the bombing campaign. By placing the emphasis more or less on the same thematic areas as the world media, but by crucially reversing the line of reasoning (e.g. the refugee problem was blamed on the NATO bombing raids and not on Serbian atrocities, the Greek media invariably remained anti-war, anti-NATO and anti-Albanian in many particular cases, and in principle pro-Serb throughout. A study of the general media and the specific
The Greek Concept of the State
Directory of Open Access Journals (Sweden)
Valentin Kalan
2010-12-01
Full Text Available The starting-point of my paper is the general recognition of the importance of Ancient Greek democracy and Greek political philosophy for modern democracy and for the assessment of political activity today. Here I draw on the studies by Castoriadis and Hansen. With regard to the ancient definitions of the state, Aristotle’s distinctive feature is that he takes into account the topographical and political-administrative aspects, while Plato’s definitions are – predictably –characterised by the notion that a politician is one who administers state affairs on the basis of his knowledge. The discussion of the entry polis in theEtymologicum Magnum is accompanied by a brief survey of the more recent etymological explanations from the perspective of semantics. Language issues are further addressed in the section on synonyms for the polis, such as ἀκρόπολις, ἄστυ, χώρα, ἄνθρωποι, δῆμος, κοινωνία, πατρίς, ἔθνος. Describing the basic characteristics of the concept of the state, the paper begins with the territory or space, which is often merely touched upon in political theory as the latter prefers to concentrate on the functioning of the political system. According to Aristotle, the territory or space is, like the climate, an external condition of the state, but at the same time a basic one, determined by Nature, φύσις, herself. The discussion of the populace from a political perspective dwells on the Greek vocabulary referring to citizens, male and female. Among the characteristics of the Greek concept of the state, particular emphasis is placed on the religious and mythological foundation of its politics, which is evident in the worship of gods/goddesses as the tutelary deities of cities (such as Zeus, Athena, Hera, Apollo, etc., with their temples, in the cult of the hearth goddess Hestia, and in the Tholos as the Prytaneum building.

Full Text Available Travel writing has been viewed as one of the main sources of national typologies and is often held responsible for the consolidation of stereotypes about otherness and for the promotion of an imperialist agenda. This paper aims to investigate conceptions of Greekness in contemporary Greek travelogues which involve a rethinking of stereotypical national representations. The analysis proceeds by proposing the method of “questioning home” in travelogues through diffracted gazes towards the traveller’s homeland as a result of his encounter with otherness. In the second part, Greekness is explored beyond the nation-state approach and the long-held national stereotype of the “Greek particularism”, Greece’s isolation because of the country’s unresolved tension between East and West. A. Vistonitis’ and M. Kassolas’s travelogues reporting their travels to the East (China and to the West (USA respectively at the end of the 20th century are examined as case-studies. Through narrators’ dialogues with their hosts and the raising of relevant political and geopolitical issues, “transnational” conceptions of Greek identity are explored: the notions of “diaspora”, “cosmopolitan citizenship”, “openness” and “connectivity” challenge the national narration based on “purity” and “exclusion”, and facilitate the investigation of potential roles for Greece in the globalized world of the early 21st century.
The Table of Chords and Greek Trigonometry
Directory of Open Access Journals (Sweden)
Stefano Buscherini
2010-12-01
Full Text Available Trigonometry was born due to the need of ancient astronomy to calculate and to predict the movement of the heavenly bodies. However it is hard to know who the founder of this mathematical branch was: it is likely that its origins date back to Hipparchus of Nicaea who compiled the first table of chords, which are the forerunners of the modern trigonometric function “sine”. Nevertheless the most ancient existing work on trigonometry is the Almagest of Ptolemy in which the author describes the mathematical steps that are necessary for the compilation of the table of chords. These steps are based on more ancient theories and for this reason one gets the impression that they could be the result of a preparatory study. This article is not only a brief survey of Greek trigonometry but it also analyzes the Greek numeration system, the sexagesimal fractions and the arithmetical operations which were used in the calculation of the chords.

The narrative of caesarean birth appears on several occasions in Greek mythology: in the birth of Dionysus is the God of the grape harvest and winemaking and wine; in the birth of Asclepius the God of medicine and healing; and in the birth of Adonis the God of beauty and desire. It is possible, however not obligatory, that it was not solely a fantasy but also reflected a contemporary medical practice.

Devastating epidemics in recent ages Greek populations.
Kotsiou, Antonia; Michalaki, Vasiliki; Anagnostopoulou, Helen N
2017-12-01
In the recent Greek ages the most devastating epidemics were plague, smallpox, leprosy and cholera. In 1816 plague struck the Ionian and Aegean Islands, mainland Greece, Constantinople and Smyrna. The Venetians ruling the Ionian Islands effectively combated plague in contrast to the Ottomans ruling all other regions. In 1922, plague appeared in Patras refugees who were expelled by the Turks from Smyrna and Asia Minor. Inoculation against smallpox was first performed in Thessaly by the Greek women, and the Greek doctors Emmanouel Timonis (1713, Oxford) and Jakovos Pylarinos (1715, Venice) made relevant scientific publications. The first leper colony opened in Chios Island. In Crete, Spinalonga was transformed into a leper island, which following the Independence War against Turkish occupation and the unification of Crete with Greece in 1913, was classified as an International Leper Hospital. Cholera struck Greece in 1853-1854 brought by the French troops during the Crimean War, and again during the Balkan Wars (1912-13) when the Bulgarian troops brought cholera to northern Greece. Due to successive wars, medical assistance was not always available, so desperate people turned many times to religion through processions in honor of local saints, for their salvation in epidemics.

Full Text Available Abstract Background Smoking is Greece's largest public health threat. Greece has the highest adult smoking prevalence among all E.U countries, which in turn possibly predisposes Greek children and adolescents to smoke. The purpose of our study was to research into the smoking habits of preschool children's parents since children of that age could be vulnerable to parental negative role modeling and to investigate into the necessity of conducting a public health awareness programme aimed at the general population. Methods A cross-sectional study was performed on the parents of children enrolled in kindergarten in western Crete-Greece (2809 parents, and interviewed during the 2004–2005 Cretan school health promotion programme. Results 63% of households had at least one parent a current smoker and in 26% both parents were found to be current smokers. Smoking prevalence among adults with preschool children was estimated at 44% (52% of fathers and 36% of mothers. Paternal education and nationality were statistically significantly related to smoking (p Conclusion Smoking prevalence is high even among parents with preschool children. Taking into account the parents' significant primary role in the children's upbringing and the effect that parental induced passive smoking has on children's health and health attitude; one can deduce that the health of Greek children is under threat. It is of major importance that educational and policy intervention measures are implemented to reduce such a situation that could contribute to promoting the initiation of smoking among Greek adolescents.

Origins of the historiography of modern Greek science.
Patiniotis, Manolis
2008-01-01
The purpose of the paper is to examine how Greek historians account for the presence of modern scientific ideas in the intellectual environment of eighteenth-century Greek-speaking society. It will also discuss the function of the history of modern Greek science in the context of Greek national historiography. As will be shown, the history of modem Greek science spent most of its life under the shadow of the history of ideas. Despite its seemingly secondary role, however, it occupied a distinctive place within national historiography because it formed the ground upon which different perceptions of the country's European identity converged. In this respect, one of the main goals of this paper is to outline the particular ideological presumptions, which shaped the historiography of modern Greek science under different historical circumstances. At the end an attempt will be made to articulate a viewpoint more in tandem with the recent methodological developments in the history of science.
Whither prometheus' liver? Greek myth and the science of regeneration.
Power, Carl; Rasko, John E J
2008-09-16
Stem-cell biologists and those involved in regenerative medicine are fascinated by the story of Prometheus, the Greek god whose immortal liver was feasted on day after day by Zeus' eagle. This myth invariably provokes the question: Did the ancient Greeks know about the liver's amazing capacity for self-repair? The authors address this question by exploring the origins of Greek myth and medicine, adopting a 2-fold strategy. First, the authors consider what opportunities the ancient Greeks had to learn about the liver's structure and function. This involves a discussion of early battlefield surgery, the beginnings of anatomical research, and the ancient art of liver augury. In addition, the authors consider how the Greeks understood Prometheus' immortal liver. Not only do the authors examine the general theme of regeneration in Greek mythology, they survey several scholarly interpretations of Prometheus' torture.

Parental characteristics of Jews and Greeks in Australia.
Parker, G; Lipscombe, P
1979-09-01
A controlled study was conducted in Sydney to assess the reported characteristics of Jewish and Greek parents. Using a measure of fundamental parental characteristics the 81 Jewish subjects differed from controls only in scoring their mothers as less caring. The 125 Greek subjects scored both parents as more overprotective; further investigation revealed that the Greek parents were overprotective of their daughters only. Findings in the latter study suggest that overprotection by Greek parents may be influenced slightly by the age of the child when migrating, and that such a cultural pattern is resistant to acculturation effects.

An overview of the Greek stonefly (Plecoptera) fauna is presented as an annotated index of all available published records. These records have resulted in an updated species list reflecting current taxonomy and species distributions of the Greek peninsula and islands. Currently, a total of 71 species and seven subspecies belonging to seven families and 19 genera are reported from Greece. There is high species endemicity of the Leuctridae and Nemouridae, particularly on the Greek islands. The endemics known from Greece comprise thirty species representing 42% of the Greek stonefly fauna. The remaining taxa are typical Balkan and Mediterranean species.
Ancient Greek Terminology in Hepatopancreatobiliary Anatomy and Surgery.
Papoulas, Michail; Douvetzemis, Stergios
2015-08-01
Most of the terminology in medicine originates from Greek or Latin, revealing the impact of the ancient Greeks on modern medicine. However, the literature on the etymology of Greek words used routinely in medical practice is sparse. We provide a short guide to the etymology and meaning of Greek words currently used in the field of hepatopancreatobiliary (HPB) anatomy and surgery. Focusing on HPB medical literature, the etymology and origin of Greek words including suffixes and prefixes are shown and analyzed. For example, anatomy (anatomia) is a Greek word derived from the prefix ana- (on, upon) and the suffix -tomy from the verb temno meaning to cut. Surgery, however, is not a Greek word. The corresponding Greek word is chirourgiki derived from cheir (hand) and ergon (action, work) meaning the action made by hands. Understanding the root of Greek terminology leads to an accurate, precise and comprehensive scientific medical language, reflecting the need for a universal medical language as a standardized means of communication within the health care sector.

Full Text Available After Ottoman colonial rule, education in Greece became an important institution for the ideological construction of a Greek national identity. This paper looks at schooling in Greece just prior to the Greek Revolution and immediately after Greek Independence, and how the Greek national school system assisted in the construction of a Greek national identity. This paper is divided into several sections. The introductory section discusses how a newly independent Greek nation-state struggled to unite the Greek people under a collective national identity. While most people at the time identified with their families, communities, and Greek Orthodox Christian religion, after Greek independence people began to see themselves as members of a broader Greek nation. The section that follows provides a discussion of Greek education during Ottoman colonial rule, and how a type of Greek identity (centered around the Greek Orthodox Christian faith was maintained through the Greek Orthodox mileu. The Greek Church ran schools, and taught Greek children how to read and write, as well as the virtues of the Orthodox Christian faith. Section three of the article looks at Greek education during the early years of the Greek nation-state. In this section the general contours of the Greek educational system are delineated. The section also discusses how the organization of the Greek national school system was borrowed from extant school models found in Western Europe. Section four describes the Greek national curriculum and how the national curriculum would help to teach future generations of Greek citizens what it meant to be Greek. This is further reinforced in the Greek school textbook, which is part of the discussion in section five. Section five concludes with the role of education and its implications in uniting nations from around the world.

Arithmetic noncommutative geometry
Marcolli, Matilde
2005-01-01
Arithmetic noncommutative geometry denotes the use of ideas and tools from the field of noncommutative geometry, to address questions and reinterpret in a new perspective results and constructions from number theory and arithmetic algebraic geometry. This general philosophy is applied to the geometry and arithmetic of modular curves and to the fibers at archimedean places of arithmetic surfaces and varieties. The main reason why noncommutative geometry can be expected to say something about topics of arithmetic interest lies in the fact that it provides the right framework in which the tools of geometry continue to make sense on spaces that are very singular and apparently very far from the world of algebraic varieties. This provides a way of refining the boundary structure of certain classes of spaces that arise in the context of arithmetic geometry, such as moduli spaces (of which modular curves are the simplest case) or arithmetic varieties (completed by suitable "fibers at infinity"), by adding boundaries...

Functional categories in agrammatism: evidence from Greek.
Stavrakaki, Stavroula; Kouvava, Sofia
2003-07-01
The aim of this study is twofold. First, to investigate the use of functional categories by two Greek agrammatic aphasics. Second, to discuss the implications of our findings for the characterization of the deficit in agrammatism. The functional categories under investigation were the following: definite and indefinite articles, personal pronouns, aspect, tense, subject-verb agreement, wh-pronouns, complementizers and the mood marker na (=to). Based on data collected through different methods, it is argued that the deficit in agrammatism cannot be described in terms of a structural account but rather by means of difficulties in the implementation of grammatical knowledge.
Dietary Habits of Greek Primary School Children
Piperakis, S. M.; Papadimitriou, V.; Zafiropoulou, M.; Piperakis, A. S.; Zisis, P.
2007-06-01
The purpose of this study was to assess Greek primary (1st to 6th grade) school children's dietary habits and the factors influencing them. Our results show that children know the value of different foods. The socio-economic status of father has no effect on the attitude of children towards choosing their diet, however, mothers' educational status appears to have an effect on their children's behaviour. Place of residence (urban or semi-rural areas) and gender does not influence their knowledge about different diets. It was, finally, shown that as children grow older they tend to eat less healthy foods.

[Gods, women and pharmacy in Greek Mythology].
Vons, J
2001-01-01
The study of Greek Mythology fully justifies Herophilus's phrase: "Medicines are the hands of Gods" (third cent. B.C.). A number of Gods are said to be the inventors of the drugs which are useful to men. Their names are still alive in the scholarly or popular appellations of a great many medicinal herbs. However, insofar as the action of a drug (of a Pharmakon) remains mysterious, one finds it in essentially female practices as well as in medicine. The study of these ancient beliefs, which have survived in spite of the progress of twentieth century science, can develop the history of epistemology of pharmacy by stimulating interdisciplinary research.
The Puzzle of the Missing Greek Exports
Uwe Boewer; Vasiliki Michou; Christoph Ungerer

Why is Greece such a surprisingly closed economy? We employ a gravity model of trade to explain the appallingly poor export performance of Greece and argue that weak institutional quality accounts for a large part of this shortfall. Using a rich dataset of bilateral value-added exports of goods and services of 39 exporters and 56 importers for 18 sectors, we first estimate that Greece exports ? less than what regular international trade patterns would predict on basis of Greek GDP, the size o...
Homosexuality according to ancient Greek physicians.
Laios, K; Moschos, M M; Koukaki, E; Kontaxaki, M-I; Androutsos, G
2017-01-01
Homosexuality and pedophilia in ancient Greece greatly concerned many researchers who were mainly interested in highlighting the social aspect of this phenomenon in ancient Greek society. An important source on the subject was the paintings of a man and his lover in attic black and red figured pottery, up to the end of the 5th century BC. Another main source was the information that derived from the texts of ancient Greek literature, especially poetry. Homosexuality was not only referring to relationships between males, but it was also manifested in lesbian love. It is believed that in the Homeric world homosexuality was not favored. In Greek society of the archaic period, the restriction of women at home, the satisfaction of sexual needs with courtesans, the marriage for the purpose of maintaining and managing the property, put women aside, marginalizing them in terms of social life, impeding the cultivation of emotional relationships between sexes. At the same time, in the society of those times, the aristocratic ideal, the constant communication of men during military training and the war, the male nudity in sports and the promotion of beauty and bravery in athletic contests, as well as the gatherings and the entertainment of men at the symposia, created a suitable substrate in which male homosexuality could develop. In this context, pedophile relationships were developed mainly during the archaic period, as recorded on vase paintings, where a mature man developed a special relationship with a teenager of the same social class. The mature man had the role of mentor for the juvenile, he would look after him and cover his living expenses and education cost. In this relationship, exhibiting predominantly the social dimension of an initiation process and introduction to adult life, the erotic homosexual intercourse could find a place to flourish. The above-mentioned relationship could not last forever, given that this would later transform into an emotional

The authors report on new chemical and lead isotopic results and interpretations of archaic Greek silver coins from the Asyut hoard which was buried around 475 B.C. Aeginetan coins were of central interest in this study. Possible ancient silver mines were explored in the Aegean region in the course of several geologic expeditions, and chemically and isotopically investigated. Some of the silver sources in Greece were traced by combination of the analytical methods and questions of provenance were solved. In addition, processes of silver smelting and refining were studied. Results and implications of this work are summarized in the final section on Conclusions. (orig.) [de
Greek Astronomy and the Medieval Arabic Tradition
Saliba, George
2002-07-01
Islamic scholars of the Middle Ages are often credited with preserving the scientific writings of Antiquity through the Dark Ages of Europe. Saliba argues that the medieval Islamic astronomers did far more—actually correcting and improving on Greek astronomy by creating new mathematical tools to explain the motions of celestial objects. These tools were so useful that Copernicus appears to have borrowed them for use in his heliocentric cosmology. In this new light, the medieval Islamic astronomers played a fundamental role in the scientific revolution that was forged in Europe during the Renaissance.

The art of providing resuscitation in Greek mythology.
Siempos, Ilias I; Ntaidou, Theodora K; Samonis, George
2014-12-01
We reviewed Greek mythology to accumulate tales of resuscitation and we explored whether these tales could be viewed as indirect evidence that ancient Greeks considered resuscitation strategies similar to those currently used. Three compendia of Greek mythology: The Routledge Handbook of Greek Mythology, The Greek Myths by Robert Graves, and Greek Mythology by Ioannis Kakridis were used to find potentially relevant narratives. Thirteen myths that may suggest resuscitation (including 1 case of autoresuscitation) were identified. Methods to attempt mythological resuscitation included use of hands (which may correlate with basic life support procedures), a kiss on the mouth (similar to mouth-to-mouth resuscitation), application of burning torches (which might recall contemporary use of external defibrillators), and administration of drugs (a possible analogy to advanced life support procedures). A careful assessment of relevant myths demonstrated that interpretations other than medical might be more credible. Although several narratives of Greek mythology might suggest modern resuscitation techniques, they do not clearly indicate that ancient Greeks presaged scientific methods of resuscitation. Nevertheless, these elegant tales reflect humankind's optimism that a dying human might be restored to life if the appropriate procedures were implemented. Without this optimism, scientific improvement in the field of resuscitation might not have been achieved.

Developments in special geometry
International Nuclear Information System (INIS)
Mohaupt, Thomas; Vaughan, Owen
2012-01-01
We review the special geometry of N = 2 supersymmetric vector and hypermultiplets with emphasis on recent developments and applications. A new formulation of the local c-map based on the Hesse potential and special real coordinates is presented. Other recent developments include the Euclidean version of special geometry, and generalizations of special geometry to non-supersymmetric theories. As applications we discuss the proof that the local r-map and c-map preserve geodesic completeness, and the construction of four- and five-dimensional static solutions through dimensional reduction over time. The shared features of the real, complex and quaternionic version of special geometry are stressed throughout.

Health Narratives in the Greek Translated Press

Themis Panagiotis Kaniklidou
2016-08-01
Full Text Available This paper looks see how meaning is constructed in translated news texts about health and science and awards a narrative potential to unforced translation shifts, moving along the theoretical lines of Baker's Narrative Theory (2006. The thematic thread of health zooms in on “emotional frames” (Nabi, 2003 of risk and fear of human health that is narrated as being 'under attack’ by potentially dangerous diseases. Themes also orbit around schemas that promote hope and optimism about science represented as coming to the rescue of man from fear of the disease. The data consists of 21 pairs of English-Greek health news articles culled from the Greek newspapers I Kathimerini, To Vima and Ta Nea. Findings point towards translation as a process that employs lexicogrammatical and intrasentential configurations to a give emphasis to the risk or hope dimensions underlying a heath or science story, b enable the reflection or emergence of a cascade of public, conceptual and master narratives.
Succinct history of Greek cardiac surgery.
Apostolakis, Efstratios; Koletsis, Efstratios; Dougenis, Dimitrios
2008-01-01
The development and evolution of Greek Cardiac Surgery (GCS) has followed the international cardiothoracic surgery after the invention of cardiopulmonary bypass machine by John Gibbon in 1953. Chronologically, the development of GCS could be divided in four periods: (a) the first or essay period (1950-1960) characterized by the lack of organization, the experimentation and hesitation from the surgeons' side, and the reluctance from the patients' side to have an operation in Greece. (b) The second or stabilization period (1960-1970) is the period during which several separate cardiovascular departments were organized and performed the first valve replacement in 1964. (c) The third or "strengthening" period (1970-1985), during which Greek surgeons were trained abroad and adopted new methods and techniques of surgical therapy. The first operations of coronary artery bypass grafting and aortic aneurysm were performed (1973-1975). Various purely Cardiothoracic Centers were founded in Athens and Thessalonica and cardiac surgery became a routine operation. However, these centers were numerically not enough to cover the demand of patients in need of cardiac surgery. (d) The fourth or maturity period (1985 till today). It is characterized by the creation of private cardiac surgery departments and the gradual establishment of new university centers at the periphery, which along with the Onassis Cardiac Center, eliminated any need for patients to leave the country.
Cases of Trephination in Ancient Greek Skulls
Directory of Open Access Journals (Sweden)
Vasiliki Ζafiri
2012-01-01
Full Text Available Background: Trephination, or trepanning, is considered to be one of the most ancient surgical operations with an especially extensive geographical incidence, both in the New World and in the Old. In Europe, more than 200 finds of trephination have been found, from Scandinavia to the Balkans. The technique of trephination or trepanning covers overall the last 10,000 years and exhibits great versatility and adjustability in the knowledge, technical means, therapeutic needs, prejudices and social standards of each period and of each population group. Hippocrates was the one to classify for the first time the kinds of cranial fractures and define the conditions and circumstances for carrying out a trepanning.Aim: The present research aims to investigate the Greek cranial trephinations on sculls from the collection of the Anthropological Museum of the Medical School of Athens that come from archaeological excavations.Method: Skulls were examined by macroscopic observation with reflective light. Furthermore, radiographic representation of the skulls was used.Results: The anthropological researches and the studies of anthropological skeleton remains that came out during archaeological excavations from different eras and areas have given information about the medical practices in the very important geographic area of Greece and in particular, we referred to cases of Greek trephinations.
Cyclopia: from Greek antiquity to medical genetics.
Kalantzis, George C; Tsiamis, Costas B; Poulakou-Rebelakou, Effie L
2013-01-01
Cyclops are among the best-known monsters of Greek mythology, also mentioned in art and literature. According to the most recent scientific knowledge, the malformations caused by defective development of the anterior brain and midline mesodermal structures include cyclopia (synophthalmos), ethmocephaly, cebocephaly and arrhinencephaly. These severe forebrain lesions often are accompanied by severe systemic malformations, and affected infants rarely survive. Neither true cyclopia nor synophthalmos are compatible with life because an anomalous development of the brain is involved. Thus, it is difficult to assume that ancient Greeks drew their inspiration from an adult patient suffering from cyclopia. Cyclops appear for the first time in literature in Homer's Odyssey (8th-7th century BC) and one of them, Polyphemus, is blinded by the hero of the epic poem. The description of the creature is identical with patients suffering from cyclopia; eyes are fused and above the median eye there is a proboscis, which is the result of an abnormal development of the surface ectodermal structures covering the brain. The next literature appearance of Cyclops is at the end of 7th century BC in "Theogonia", written by Hesiodus. Another interesting description is made by Euripides in his satyr play entitled 'Cyclops' (5th century BC). In conclusion, though it is not certain whether Homer's description of Cyclops was based on his personal experience or the narration of his ancestors, there is no doubt that the ophthalmological disease, cyclopia, was named after this mythical creature.
The Greek crisis: Causes and implications
Directory of Open Access Journals (Sweden)
Vlamis Prodromos
2010-01-01
Full Text Available This paper presents and critically discusses the origins and causes of the Greek fiscal crisis and its implications for the euro currency as well as the SEE economies. In the aftermath of the 2007-2009 financial crisis the enormous increase in sovereign debt has emerged as an important negative outcome, since public debt was dramatically increased in an effort by the US and the European governments to reduce the accumulated growth of private debt in the years preceding the recent financial turmoil. Although Greece is the country member of the eurozone that has been in the middle of this ongoing debt crisis, since November 2009 when it was made clear that its budget deficit and mainly its public debt were not sustainable, Greece’s fiscal crisis is not directly linked to the 2007 US subprime mortgage loan market crisis. As a result of this negative downturn the Greek government happily accepted a rescue plan of 110 billion euros designed and financed by the European Union and the IMF. A lengthy austerity programme and a fiscal consolidation plan have been put forward and are to be implemented in the next three years.

In this thesis, a formulation of a Lorentzian quantum geometry based on the framework of causal fermion systems is proposed. After giving the general definition of causal fermion systems, we deduce space-time as a topological space with an underlying causal structure. Restricting attention to systems of spin dimension two, we derive the objects of our quantum geometry: the spin space, the tangent space endowed with a Lorentzian metric, connection and curvature. In order to get the correspondence to classical differential geometry, we construct examples of causal fermion systems by regularizing Dirac sea configurations in Minkowski space and on a globally hyperbolic Lorentzian manifold. When removing the regularization, the objects of our quantum geometry reduce to the common objects of spin geometry on Lorentzian manifolds, up to higher order curvature corrections.
Methods of information geometry
Amari, Shun-Ichi
2000-01-01
Information geometry provides the mathematical sciences with a new framework of analysis. It has emerged from the investigation of the natural differential geometric structure on manifolds of probability distributions, which consists of a Riemannian metric defined by the Fisher information and a one-parameter family of affine connections called the \\alpha-connections. The duality between the \\alpha-connection and the (-\\alpha)-connection together with the metric play an essential role in this geometry. This kind of duality, having emerged from manifolds of probability distributions, is ubiquitous, appearing in a variety of problems which might have no explicit relation to probability theory. Through the duality, it is possible to analyze various fundamental problems in a unified perspective. The first half of this book is devoted to a comprehensive introduction to the mathematical foundation of information geometry, including preliminaries from differential geometry, the geometry of manifolds or probability d...

Geometry on the space of geometries

Christodoulakis, T.; Zanelli, J.

We discuss the geometric structure of the configuration space of pure gravity. This is an infinite dimensional manifold, M, where each point represents one spatial geometry g ij (x). The metric on M is dictated by geometrodynamics, and from it, the Christoffel symbols and Riemann tensor can be found. A ''free geometry'' tracing a geodesic on the manifold describes the time evolution of space in the strong gravity limit. In a regularization previously introduced by the authors, it is found that M does not have the same dimensionality, D, everywhere, and that D is not a scalar, although it is covariantly constant. In this regularization, it is seen that the path integral measure can be absorbed in a renormalization of the cosmological constant. (author). 19 refs
The Greek Qur’an : Scholarship and evaluations
Høgel, Christian
2012-01-01
The early Greek translation of the Qur’an has received little notice, not least due to the many claims that it was a faulty and inadequate attempt of rendering the Qur’an into Greek. This article argues that the faults are very few and minor, and that the early translation (from before 870 CE) should instead be read as a serious example of early Qur’anic interpretation as well as a documentation of early Greek readership of the Qur’an.

The Greek Public Debt Path: From Zero to Infinity
Sardelis, Dimitris
2012-01-01
The aim of the present article is to treat the Greek public debt issue strictly as a curve fitting problem. Thus, based on Eurostat data and using the Mathematica technical computing software, an exponential function that best fits the data is determined modelling how the Greek public debt expands with time. Exploring the main features of this best fit model, it is concluded that the Greek public debt cannot possibly be serviced in the long run unless a radical growth is implemented and/or pa...
Astrology in Ancient Greek and Roman Culture
Campion, Nicholas
2018-04-01
This article deals with astrology in Greek and Roman culture. It considers astrology's theoretical background, technical basis, interpretative conventions, social functions, religious and political uses, and theory of fate, as well as critiques of it. Astrology is the name given to a series of diverse practices based in the idea that the stars, planets, and other celestial phenomena possess significance and meaning for events on Earth. It assumes a link between Earth and sky in which all existence—spiritual, psychological, and physical—is interconnected. Most premodern cultures practiced a form of astrology. A particularly complex variety of it evolved in Mesopotamia in the first and second millennia BCE from where it was imported into the Hellenistic world from the early 4th century BCE onward. There it became attached to three philosophical schools: those pioneered by Plato, Aristotle, and the Stoics, all of which shared the assumption that the cosmos is a single, living, integrated whole. Hellenistic astrology also drew on Egyptian temple culture, especially the belief that the soul could ascend to the stars. By the 1st century CE the belief in the close link between humanity and the stars had become democratized and diversified into a series of practices and schools of thought that ranged across Greek and Roman culture. It was practiced at the imperial court and in the street. It could be used to predict individual destiny, avert undesirable events, and arrange auspicious moments to launch new enterprises. It could advise on financial fortunes or the condition of one's soul. It was conceived of as natural science and justified by physical influences, or considered to be divination, concerned with communication with the gods and goddesses. In some versions the planets were neither influences nor causes of events on Earth, but timing devices, which indicated the ebb and flow of human affairs, like the hands on a modern clock. Astrology had a radical view of
Andronikos I Komnenos: A Greek Tragedy

Full Text Available The Annals of Niketas Choniates depict Emperor Andronikos I Komnenos (1183-1185 in certain aspects of his lifestyle as a mirror image of his first cousin, Emperor Manuel I Komnenos (1143-1180. The life and death of Andronikos I Komnenos provide us with a window into the aesthetic, moral, intellectual, religious, economic and emotional world of Byzantine society in the 12th century. It was thanks to the Byzantine empire that the ancient texts were preserved and transmitted. Ancient Greek culture and reason, in particular, continued to inform Christian values while, at the same time, both could be in radical conflict. The tragic reign of Andronikos as presented by Niketas Choniates conforms to Aristotle's principles of classical drama, but there is a fundamental disagreement between the author of the Poetics and the historian as to what constitutes tragedy, which underlines this conflict.

2016-06-01
Full Text Available Capital structure is essential for the survival, growth and performance of a firm. There has been a growing interest worldwide in identifying the factors associated with debt leverage. This article aims to investigate the factors affecting the capital structure of companies listed on the Athens Stock Exchange (ASE. The data set used is composed of indicators reflecting the financial position and performance of 40 firms listed on the ASE in 2014. Using a regression model we estimate in what extent the financial structure of companies is affected by performance indicators and other specific factors like the field of activity or the size of the firms. The results obtained show an important influence of share of tangible assets in total assets of the company on the financial leverage, as main variable selected in order to reflect the capital structure of Greek companies.
Complex and symplectic geometry

This accessible approach features two varieties of proofs: stereometric and planimetric, as well as elementary proofs that employ only the simplest properties of the plane. A short history of geometry precedes a systematic exposition of the principles of non-Euclidean geometry.Starting with fundamental assumptions, the author examines the theorems of Hjelmslev, mapping a plane into a circle, the angle of parallelism and area of a polygon, regular polygons, straight lines and planes in space, and the horosphere. Further development of the theory covers hyperbolic functions, the geometry of suff
The profile of the Greek 'XXL' family.

2011-10-01
To identify Greek families in which all members were overweight or obese (XXL families) and to describe their profile with regard to their socio-economic status and their eating behaviours and practices. A prospective cohort study. The metropolitan area of Kavala. We recruited children aged 11 and 12 years from twelve primary schools, and their parents, from volunteers. Auxologic measurements of the children included height and weight. A structured questionnaire pertaining to information on the socio-economic status of the family, anthropometric values and educational status of parents, dietary habits and the availability of various food products and beverages at home, as well as dietary intake, physical activity, time spent sleeping and time spent watching television, was filled in by one of the parents of each child. A total of 331 families finally participated. In sixty-one families (18·43 %) both parents and child were either overweight or obese (XXL family), and in seven of these families all members were obese. Only twenty-eight families (8·46 %) had all members with a normal BMI. The XXL family was associated with lower educational status of both parents, whereas a higher percentage of XXL families resided in rural areas and had lower income. Skipping breakfast and spending more than 3 h in front of a screen every day were more frequently observed in XXL families. With regard to the availability of various food products and beverages at home, no significant differences were observed between XXL families and the rest of the studied families. Greek XXL families have lower educational status and lower annual income.
Penile representations in ancient Greek art.
Rempelakos, L; Tsiamis, C; Poulakou-Rebelakou, E
2013-12-01
The presentation of the cult of phallus in ancient Greece and the artistic appearance of the phenomenon on vase figures and statues, as indicative of the significant role of the male genitalia in all fertility ceremonies. The examination of a great number of penile representations from the ancient Greek pottery and sculpture and the review of the ancient theater plays (satiric dramas and comedies ). Phallus in artistic representation is connected either with gods of fertility, such as the goat-footed and horned Pan or the ugly dwarf Priapus or the semi-animal nailed figures Satyrs, devotees of the god Dionysus accompanying him in all ritual orgiastic celebrations. Phallus also symbolizes good luck, health and sexuality: people bear or wear artificial phalli exactly like the actors as part of their costume or carry huge penises during the festive ritual processions. On the contrary, the Olympic gods or the ordinary mortals are not imaged ithyphallic; the ideal type of male beauty epitomized in classical sculpture, normally depicts genitals of average or less than average size. It is noteworthy that many of these images belong to athletes during or immediately after hard exercise with the penis shrunk. The normal size genitalia may have been simply a convention to distinguish normal people from the gods of sexuality and fertility, protectors of the reproductive process of Nature. The representation of the over-sized and erected genitalia on vase figures or statues of ancient Greek art is related to fertility gods such as Priapus, Pan and Satyrs and there is strong evidence that imagination and legend were replacing the scientific achievements in the field of erectile function for many centuries.
Greek paideia and terms of probability
Directory of Open Access Journals (Sweden)
Fernando Leon Parada
2016-06-01
Full Text Available This paper addresses three aspects of the conceptual framework for a doctoral dissertation research in process in the field of Mathematics Education, in particular, in the subfield of teaching and learning basic concepts of Probability Theory at the College level. It intends to contrast, sustain and elucidate the central statement that the meanings of some of these basic terms used in Probability Theory were not formally defined by any specific theory but relate to primordial ideas developed in Western culture from Ancient Greek myths. The first aspect deals with the notion of uncertainty, with that Greek thinkers described several archaic gods and goddesses of Destiny, like Parcas and Moiras, often personified in the goddess Tyche—Fortuna for the Romans—, as regarded in Werner Jaeger’s “Paideia”. The second aspect treats the idea of hazard from two different approaches: the first approach deals with hazard, denoted by Plato with the already demythologized term ‘tyche’ from the viewpoint of innate knowledge, as Jaeger points out. The second approach deals with hazard from a perspective that could be called “phenomenological”, from which Aristotle attempted to articulate uncertainty with a discourse based on the hypothesis of causality. The term ‘causal’ was opposed both to ‘casual’ and to ‘spontaneous’ (as used in the expression “spontaneous generation”, attributing uncertainty to ignorance of the future, thus respecting causal flow. The third aspect treated in the paper refers to some definitions and etymologies of some other modern words that have become technical terms in current Probability Theory, confirming the above-mentioned main proposition of this paper.
Possible Minoan Contributions to Greek Astronomy
Henriksson, G.; Blomberg, M.
We present the results of orientation studies of important Minoan monuments and our interpretations of their significance for later Greek astronomy. The studies have been made on the hypothesis that the Minoans, via the Mycenaeans, were the source of the Greek lunisolar calendar and the use of bright stars to signal when to begin activities of economic importance, e.g., ploughing and sailing. The palace at Knossos is oriented so that the first rays of the sun at the equinoxes, as they clear the ridge in the east, will strike an usual concave stone in the floor of the corridor immediately adjacent to the pillar crypt area in the west wing. This area is generally considered to b = e the most sacred part of the first palace. The palace at Zakros is oriented so that from the northern-most corridor of the west wing the moon, as it rose at the southern major standstill, would have been observed to follow the profile of the ridge opposite at the time when the first palace was built (ca 2000 BC). At two peak sanctuaries near Zakros, there are walls oriented such that they could have been used to facilitate observations of the heliacal rising and setting and also the acronychal rising and cosmical setting of the bright star Arcturus ca 1800 BC. In the Minoan ruins of the palaces at Ayia Triada and Mallia, there was constructed a small building of Mycenaean megaron type. Both are oriented to sunset at the summer solstice. We argue from these results that the Minoans had begun systematic observations of the sun, the moon and the bright star Arcturus by the end of the Early Minoan Period (ca 2000 BC). The proximity of Crete to Egypt and the Near East and the documented contact among these regions invite comparison of the calendrical uses of astronomical knowledge in the three areas in the Bronze Age.

Full Text Available Fascination with primes dates back to the Greeks and before. Primes are named by some "the elementary particles of arithmetic" as every nonprime integer is made of a unique set of primes. In this article we point to new connections between primes, geometry and physics which show that primes could be called "the elementary particles of physics" too. This study considers the problem of closely packing similar circles/spheres in 2D/3D space. This is in effect a discretization process of space and the allowable number in a pack is found to lead to some unexpected cases of prime configurations which is independent of the size of the constituents. We next suggest that a non-prime can be considered geometrically as a symmetric collection that is separable (factorable into similar parts- six is two threes or three twos for example. A collection that has no such symmetry is a prime. As a result, a physical prime aggregate is more difficult to split symmetrically resulting in an inherent stability. This "number/physical" stability idea applies to bigger collections made from smaller (prime units leading to larger stable prime structures in a limitless scaling up process. The distribution of primes among numbers can be understood better using the packing ideas described here and we further suggest that differing numbers (and values of distinct prime factors making a nonprime collection is an important factor in determining the probability and method of possible and subsequent disintegration.

The city is a vital sum of functions, of human actions, of resources and of a built and physical environment. The sustainability of cities is relatively a new area of interest, especially for the Greek cities. Only in the last decade was sustainability introduced to the Greek planning process. Unfortunately, the Greek cities do not follow the Local Agenda 21, an instrument that is trying to promote sustainability issues for the built environment. The city of Volos in Greece seems to be more s...

Coarse geometry is the study of spaces (particularly metric spaces) from a 'large scale' point of view, so that two spaces that look the same from a great distance are actually equivalent. This point of view is effective because it is often true that the relevant geometric properties of metric spaces are determined by their coarse geometry. Two examples of important uses of coarse geometry are Gromov's beautiful notion of a hyperbolic group and Mostow's proof of his famous rigidity theorem. The first few chapters of the book provide a general perspective on coarse structures. Even when only metric coarse structures are in view, the abstract framework brings the same simplification as does the passage from epsilons and deltas to open sets when speaking of continuity. The middle section reviews notions of negative curvature and rigidity. Modern interest in large scale geometry derives in large part from Mostow's rigidity theorem and from Gromov's subsequent 'large scale' rendition of the crucial properties of n...
Lectures on Symplectic Geometry
Silva, Ana Cannas
2001-01-01
The goal of these notes is to provide a fast introduction to symplectic geometry for graduate students with some knowledge of differential geometry, de Rham theory and classical Lie groups. This text addresses symplectomorphisms, local forms, contact manifolds, compatible almost complex structures, Kaehler manifolds, hamiltonian mechanics, moment maps, symplectic reduction and symplectic toric manifolds. It contains guided problems, called homework, designed to complement the exposition or extend the reader's understanding. There are by now excellent references on symplectic geometry, a subset of which is in the bibliography of this book. However, the most efficient introduction to a subject is often a short elementary treatment, and these notes attempt to serve that purpose. This text provides a taste of areas of current research and will prepare the reader to explore recent papers and extensive books on symplectic geometry where the pace is much faster. For this reprint numerous corrections and cl...

Mathematical billiards describe the motion of a mass point in a domain with elastic reflections off the boundary or, equivalently, the behavior of rays of light in a domain with ideally reflecting boundary. From the point of view of differential geometry, the billiard flow is the geodesic flow on a manifold with boundary. This book is devoted to billiards in their relation with differential geometry, classical mechanics, and geometrical optics. The topics covered include variational principles of billiard motion, symplectic geometry of rays of light and integral geometry, existence and nonexistence of caustics, optical properties of conics and quadrics and completely integrable billiards, periodic billiard trajectories, polygonal billiards, mechanisms of chaos in billiard dynamics, and the lesser-known subject of dual (or outer) billiards. The book is based on an advanced undergraduate topics course (but contains more material than can be realistically taught in one semester). Although the minimum prerequisit...
Introduction to tropical geometry
Maclagan, Diane
2015-01-01
Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of t...

We analyze some properties of the four dimensional supergravity theories which originate from five dimensions upon reduction. They generalize to N>2 extended supersymmetries the d-geometries with cubic prepotentials, familiar from N=2 special K\\"ahler geometry. We emphasize the role of a suitable parametrization of the scalar fields and the corresponding triangular symplectic basis. We also consider applications to the first order flow equations for non-BPS extremal black holes.

CMS faces real challenges with upgrade of the CMS detector through 2020 and beyond. One of the challenges, from the software point of view, is managing upgrade simulations with the same software release as the 2013 scenario. We present the CMS geometry description software model, its integration with the CMS event setup and core software. The CMS geometry configuration and selection is implemented in Python. The tools collect the Python configuration fragments into a script used in CMS workflow. This flexible and automated geometry configuration allows choosing either transient or persistent version of the same scenario and specific version of the same scenario. We describe how the geometries are integrated and validated, and how we define and handle different geometry scenarios in simulation and reconstruction. We discuss how to transparently manage multiple incompatible geometries in the same software release. Several examples are shown based on current implementation assuring consistent choice of scenario conditions. The consequences and implications for multiple/different code algorithms are discussed.
Software Geometry in Simulations
Alion, Tyler; Viren, Brett; Junk, Tom
2015-04-01
The Long Baseline Neutrino Experiment (LBNE) involves many detectors. The experiment's near detector (ND) facility, may ultimately involve several detectors. The far detector (FD) will be significantly larger than any other Liquid Argon (LAr) detector yet constructed; many prototype detectors are being constructed and studied to motivate a plethora of proposed FD designs. Whether it be a constructed prototype or a proposed ND/FD design, every design must be simulated and analyzed. This presents a considerable challenge to LBNE software experts; each detector geometry must be described to the simulation software in an efficient way which allows for multiple authors to easily collaborate. Furthermore, different geometry versions must be tracked throughout their use. We present a framework called General Geometry Description (GGD), written and developed by LBNE software collaborators for managing software to generate geometries. Though GGD is flexible enough to be used by any experiment working with detectors, we present it's first use in generating Geometry Description Markup Language (GDML) files to interface with LArSoft, a framework of detector simulations, event reconstruction, and data analyses written for all LAr technology users at Fermilab. Brett is the other of the framework discussed here, the General Geometry Description (GGD).
Introduction to combinatorial geometry

The combinatorial geometry package as used in many three-dimensional multimedia Monte Carlo radiation transport codes, such as HETC, MORSE, and EGS, is becoming the preferred way to describe simple and complicated systems. Just about any system can be modeled using the package with relatively few input statements. This can be contrasted against the older style geometry packages in which the required input statements could be large even for relatively simple systems. However, with advancements come some difficulties. The users of combinatorial geometry must be able to visualize more, and, in some instances, all of the system at a time. Errors can be introduced into the modeling which, though slight, and at times hard to detect, can have devastating effects on the calculated results. As with all modeling packages, the best way to learn the combinatorial geometry is to use it, first on a simple system then on more complicated systems. The basic technique for the description of the geometry consists of defining the location and shape of the various zones in terms of the intersections and unions of geometric bodies. The geometric bodies which are generally included in most combinatorial geometry packages are: (1) box, (2) right parallelepiped, (3) sphere, (4) right circular cylinder, (5) right elliptic cylinder, (6) ellipsoid, (7) truncated right cone, (8) right angle wedge, and (9) arbitrary polyhedron. The data necessary to describe each of these bodies are given. As can be easily noted, there are some subsets included for simplicity
Developmental surface and phonological dyslexia in both Greek and English.
Sotiropoulos, Andreas; Hanley, J Richard
2017-11-01
The hallmark of developmental surface dyslexia in English and French is inaccurate reading of words with atypical spelling-sound correspondences. According to Douklias, Masterson and Hanley (2009), surface dyslexia can also be observed in Greek (a transparent orthography for reading that does not contain words of this kind). Their findings suggested that surface dyslexia in Greek can be characterized by slow reading of familiar words, and by inaccurate spelling of words with atypical sound-spelling correspondences (Greek is less transparent for spelling than for reading). In this study, we report seven adult cases whose slow reading and impaired spelling accuracy satisfied these criteria for Greek surface dyslexia. When asked to read words with atypical grapheme-phoneme correspondences in English (their second language), their accuracy was severely impaired. A co-occurrence was also observed between impaired spelling of words with atypical phoneme-grapheme correspondences in English and Greek. These co-occurrences provide strong evidence that surface dyslexia genuinely exists in Greek and that slow reading of real words in Greek reflects the same underlying impairment as that which produces inaccurate reading of atypical words in English. Two further individuals were observed with impaired reading and spelling of nonwords in both languages, consistent with developmental phonological dyslexia. Neither of the phonological dyslexics read words slowly. In terms of computational models of reading aloud, these findings suggest that slow reading by dyslexics in transparent orthographies is the consequence of a developmental impairment of the lexical (Coltheart, Rastle, Perry, Langdon, & Zeigler, 2001; Perry, Ziegler, & Zorzi, 2010) or semantic reading route (Plaut, McClelland, Seidenberg, & Patterson, 1996). This outcome provides evidence that the neurophysiological substrate(s) that support the lexical/semantic and the phonological pathways that are involved in reading

This paper presents an extensive analysis of the Greek electricity market for the next 7-year period (2014–2020) based on an hour-by-hour simulation considering five different RES technologies, namely wind, PV, small hydro, biomass and CHP with emphasis on PV integration. The impact of RES penetration on the electricity market operation is evaluated under two different models regarding the organization of the Greek wholesale day-ahead electricity market: a mandatory power pool for year 2014 (current market design) and a power exchange for the period 2015–2020 (Target Model). An integrated software tool is used for the simulation of the current and the future day-ahead market clearing algorithm of the Greek wholesale electricity market. Simulation results indicate the impact of the anticipated large-scale RES integration, in conjunction with each market model, on specific indicators of the Greek electricity market in the long-term. - Highlights: • Analysis of the Greek electricity market for the next 7-year period (2014–2020) based on hour-by-hour simulation. • Five different RES technologies are considered with emphasis on PV integration. • A power pool (for 2014) and a power exchange (for 2015–2020) are considered. • Various market indicators are used for the analysis of the impact of the RES integration on the Greek electricity market. • Two alternative tariff schemes for the compensation of the new ground-mounted PV units from 2015 onwards are investigated
Traditional perception of Greeks in Serbian oral tradition

Full Text Available Based on material on Greeks from Vuk’s corpus of epic poems, we discuss the construction of ethnic stereotype of Greeks in Serbian language. However, the limitation of the paper’s possible conclusion lies in the nature of the corpus: Vuk had deliberately chosen one material over another, therefore, the corpus relating to Greeks cannot be considered as representative of the whole Serbian folk poems. Therefore, the discussion is limited to certain elements of the stereotype. Nevertheless, these Serbian epic folk poems contain many layers: historical, geographical, sociological, mythological and so on, with a strong foundation in traditional culture; thus, they provide an insight into geo-political situation of the time period, viewpoints, perspectives and experiences of other ethnic groups that Serbs have been into contact with. In particular, the relationship toward Greeks was marked with pronounced patriarchal attitude concerning others: we-others, ours-foreign, good-bad. In this sense, Greeks are portrayed as foreign, and as such, as a potential source of danger. On the other hand, Greeks are Christian Orthodox, which associates them with the category ours. In socio-economic sense, they were traders and wealthy, respected gentlemen. In epical-heroic profile, they were not considered as great heroes, but as "lousy army", and frequently, as unfaithful.

Internet addiction (IA) is a new disorder described in 1996 by the psychologist Kimberly Young. The aim of this paper is to estimate the percentage of IA among Greek university students. Results of a sample survey among 1876 Greek university students, 18-27 years old, are presented. The questionnaire consisted of eight questions from Young’s Diagnostic Test for Internet Addiction (YDTIA) as well as an inventory including demographic factors and questions about academic performance, computer a...
Sources of hyperbolic geometry
Stillwell, John
1996-01-01
This book presents, for the first time in English, the papers of Beltrami, Klein, and Poincaré that brought hyperbolic geometry into the mainstream of mathematics. A recognition of Beltrami comparable to that given the pioneering works of Bolyai and Lobachevsky seems long overdue-not only because Beltrami rescued hyperbolic geometry from oblivion by proving it to be logically consistent, but because he gave it a concrete meaning (a model) that made hyperbolic geometry part of ordinary mathematics. The models subsequently discovered by Klein and Poincaré brought hyperbolic geometry even further down to earth and paved the way for the current explosion of activity in low-dimensional geometry and topology. By placing the works of these three mathematicians side by side and providing commentaries, this book gives the student, historian, or professional geometer a bird's-eye view of one of the great episodes in mathematics. The unified setting and historical context reveal the insights of Beltrami, Klein, and Po...

We show that by employing the standard projected curvature as a measure of spatial curvature, we can make a certain generalization of optical geometry (Abramowicz M A and Lasota J-P 1997 Class. Quantum Grav. A 14 23-30). This generalization applies to any spacetime that admits a hypersurface orthogonal shearfree congruence of worldlines. This is a somewhat larger class of spacetimes than the conformally static spacetimes assumed in standard optical geometry. In the generalized optical geometry, which in the generic case is time dependent, photons move with unit speed along spatial geodesics and the sideways force experienced by a particle following a spatially straight line is independent of the velocity. Also gyroscopes moving along spatial geodesics do not precess (relative to the forward direction). Gyroscopes that follow a curved spatial trajectory precess according to a very simple law of three-rotation. We also present an inertial force formalism in coordinate representation for this generalization. Furthermore, we show that by employing a new sense of spatial curvature (Jonsson R 2006 Class. Quantum Grav. 23 1)) closely connected to Fermat's principle, we can make a more extensive generalization of optical geometry that applies to arbitrary spacetimes. In general this optical geometry will be time dependent, but still geodesic photons move with unit speed and follow lines that are spatially straight in the new sense. Also, the sideways experienced (comoving) force on a test particle following a line that is straight in the new sense will be independent of the velocity
Computational synthetic geometry
Bokowski, Jürgen
1989-01-01
Computational synthetic geometry deals with methods for realizing abstract geometric objects in concrete vector spaces. This research monograph considers a large class of problems from convexity and discrete geometry including constructing convex polytopes from simplicial complexes, vector geometries from incidence structures and hyperplane arrangements from oriented matroids. It turns out that algorithms for these constructions exist if and only if arbitrary polynomial equations are decidable with respect to the underlying field. Besides such complexity theorems a variety of symbolic algorithms are discussed, and the methods are applied to obtain new mathematical results on convex polytopes, projective configurations and the combinatorics of Grassmann varieties. Finally algebraic varieties characterizing matroids and oriented matroids are introduced providing a new basis for applying computer algebra methods in this field. The necessary background knowledge is reviewed briefly. The text is accessible to stud...
Discrete and computational geometry
Devadoss, Satyan L
2011-01-01
Discrete geometry is a relatively new development in pure mathematics, while computational geometry is an emerging area in applications-driven computer science. Their intermingling has yielded exciting advances in recent years, yet what has been lacking until now is an undergraduate textbook that bridges the gap between the two. Discrete and Computational Geometry offers a comprehensive yet accessible introduction to this cutting-edge frontier of mathematics and computer science. This book covers traditional topics such as convex hulls, triangulations, and Voronoi diagrams, as well as more recent subjects like pseudotriangulations, curve reconstruction, and locked chains. It also touches on more advanced material, including Dehn invariants, associahedra, quasigeodesics, Morse theory, and the recent resolution of the Poincaré conjecture. Connections to real-world applications are made throughout, and algorithms are presented independently of any programming language. This richly illustrated textbook also fe...

Recently, the application of geometry and conformal mappings to artificial materials (metamaterials) has attracted the attention in various research communities. These materials, characterized by a unique man-made structure, have unusual optical properties, which materials found in nature do not exhibit. By applying the geometry and conformal mappings theory to metamaterial science, it may be possible to realize so-called "Harry Potter cloaking device". Although such a device is still in the science fiction realm, several works have shown that by using such metamaterials it may be possible to control the direction of the electromagnetic field at will. We could then make an object hidden inside of a cloaking device. Here, we will explain how to design invisibility device using differential geometry and conformal mappings.

Discrete geometry investigates combinatorial properties of configurations of geometric objects. To a working mathematician or computer scientist, it offers sophisticated results and techniques of great diversity and it is a foundation for fields such as computational geometry or combinatorial optimization. This book is primarily a textbook introduction to various areas of discrete geometry. In each area, it explains several key results and methods, in an accessible and concrete manner. It also contains more advanced material in separate sections and thus it can serve as a collection of surveys in several narrower subfields. The main topics include: basics on convex sets, convex polytopes, and hyperplane arrangements; combinatorial complexity of geometric configurations; intersection patterns and transversals of convex sets; geometric Ramsey-type results; polyhedral combinatorics and high-dimensional convexity; and lastly, embeddings of finite metric spaces into normed spaces. Jiri Matousek is Professor of Com...

The theory of complex manifolds overlaps with several branches of mathematics, including differential geometry, algebraic geometry, several complex variables, global analysis, topology, algebraic number theory, and mathematical physics. Complex manifolds provide a rich class of geometric objects, for example the (common) zero locus of any generic set of complex polynomials is always a complex manifold. Yet complex manifolds behave differently than generic smooth manifolds; they are more coherent and fragile. The rich yet restrictive character of complex manifolds makes them a special and interesting object of study. This book is a self-contained graduate textbook that discusses the differential geometric aspects of complex manifolds. The first part contains standard materials from general topology, differentiable manifolds, and basic Riemannian geometry. The second part discusses complex manifolds and analytic varieties, sheaves and holomorphic vector bundles, and gives a brief account of the surface classifi...

This book is an introduction to the geometry of Euclidean, affine, and projective spaces with special emphasis on the important groups of symmetries of these spaces. The two major objectives of the text are to introduce the main ideas of affine and projective spaces and to develop facility in handling transformations and groups of transformations. Since there are many good texts on affine and projective planes, the author has concentrated on the n-dimensional cases.Designed to be used in advanced undergraduate mathematics or physics courses, the book focuses on ""practical geometry,"" emphasi
Cyberbullying Among Greek High School Adolescents.

2017-05-01
To investigate the presence of cyberbullying among Greek students and the efficacy of proposed preventive interventions. Three types of high schools (private, experimental and public) with different politics on on-line aggression were enrolled. All students of the aforementioned schools were asked to complete an anonymous questionnaire. Around 62 % of the high school students experienced cyberbullying by electronic means, especially by cell phone, mostly the public school students (p 0.008). The bully was a stranger in more than 40 % of the cases. Over 60 % of the victims had not seeked help but dealt with the attack on their own. Only 20 % of the victims manifested sleep or eating disorders, physical/ psychological symptoms or changes in their social life as a consequence of the cyber-attack. Cyberbullying is a usual phenomenon among high school students. The bully is frequently unacquainted to the victim. Most of the victims are not physically or psychologically affected by the cyber-attack and do not share the event with anyone. There was a slight difference in the response of the students to cyberbullying among the different school politics of on-line aggression.

To determine the epidemiological characteristics of severe eye injuries in childhood, in a mixed urban and rural Greek setting. Retrospective analysis of 95 cases (103 eyes) of eye injuries in children younger than 17 years of age admitted to the Department of Ophthalmology, University Hospital of Patras, Greece, during a five-year period. The data were analyzed with respect to age, sex, type, cause and mode of injury, method of management, duration of hospitalization and final visual deficit. The average age was 9.8 years and males were involved in 80% of the cases. The most common type of eye injury was mechanical closed-globe injury (71.8%). Mechanical open-globe injuries were found in 21.3% of the eyes, while burns comprised 6.7% of the injuries. Most injuries were agent-related, with blows and falls being responsible most often. Multiple operations were part of the treatment in 11.6% of the eyes; 14.5% of the eyes were blinded and 15.5% had significant final visual acuity loss. These hospital-based data suggest that there is a need for health education of both parents and children, since some injuries in children could easily have been prevented.
Surrogacy: The experience of Greek commissioning women.
Papaligoura, Zaira; Papadatou, Danai; Bellali, Thalia
2015-12-01
Available studies on surrogacy are extremely limited. Findings suggest that surrogacy is experienced as problem free, with a significant number of commissioning mothers maintaining contact with the surrogates over time. To explore the experiences of Greek commissioning women regarding the surrogacy arrangement and birth of a child through surrogacy. The data of this study were collected from 7 intended mothers who had either a long history of infertility or serious health problems. Interviews were tape-recorded, transcribed and analysed employing content analysis. The analysis of the women's accounts revealed three themes: (a) a shared journey, (b) the birth of a long-awaited child, and (c) the surrogacy disclosure. The surrogacy process became the women's affairs, with their partners offering backstage support. A very close bond was developed with the surrogates, characterised by daily contacts and care-giving behaviours. While this bond was abruptly discontinued after the child's birth, it was interiorised with all participants being grateful to their surrogate. The timing and content of the surrogacy disclosure to family and child(ren) were carefully chosen by participants, who avoided providing information when egg donation was involved. Findings are reassuring for women who want to parent a child through a surrogate arrangement, and suggest that the availability of counselling services may help intended mothers to cope with disclosure issues.

Methodological remarks on studying prehistoric Greek religion
Directory of Open Access Journals (Sweden)
Petra Pakkanen
1999-01-01
Full Text Available This paper presents a methodological approach to the study of Greek religion of the period which lacks written documents, i.e. prehistory. The assumptions and interpretations of religion of that time have to be based on archaeological material. How do we define religion and cultic activity on the basis of primary archaeological material from this period, and which are the methodological tools for this difficult task? By asking questions on the nature and definition of religion and culture scholars of religion have provided us with some methodological apparatus to approach religion of the past in general, but there are models developed by archaeologists as well. Critical combination of these methodological tools leads to the best possible result. Archaeology studies the material culture of the past. History of religion studies the spiritual culture of the past. In the background the two have important theoretical and even philosophical speculations since they both deal with meanings (of things or practices and with interpretation.
Uncertainty of Volatility Estimates from Heston Greeks
Directory of Open Access Journals (Sweden)
Oliver Pfante
2018-01-01
Full Text Available Volatility is a widely recognized measure of market risk. As volatility is not observed it has to be estimated from market prices, i.e., as the implied volatility from option prices. The volatility index VIX making volatility a tradeable asset in its own right is computed from near- and next-term put and call options on the S&P 500 with more than 23 days and less than 37 days to expiration and non-vanishing bid. In the present paper we quantify the information content of the constituents of the VIX about the volatility of the S&P 500 in terms of the Fisher information matrix. Assuming that observed option prices are centered on the theoretical price provided by Heston's model perturbed by additive Gaussian noise we relate their Fisher information matrix to the Greeks in the Heston model. We find that the prices of options contained in the VIX basket allow for reliable estimates of the volatility of the S&P 500 with negligible uncertainty as long as volatility is large enough. Interestingly, if volatility drops below a critical value of roughly 3%, inferences from option prices become imprecise because Vega, the derivative of a European option w.r.t. volatility, and thereby the Fisher information nearly vanishes.

Full Text Available Background: College students’ mental health problems include depression, anxiety, panic disorders, phobias and obsessive compulsive thoughts. Aims: To investigate Greek college students’ psychopathology. Methods: During the initial evaluation, 638 college students were assessed through the following psychometric questionnaires: (a Eysenck Personality Questionnaire (EPQ; (b The Symptom Checklist-90 (SCL-90; (c The Beck Depression Inventory (BDI; (d State-Trait Anxiety Inventory (STAI. Results: State anxiety and trait anxiety were correlated, to a statistically significant degree, with the family status of the students (p = 0.024 and the past visits to the psychiatrist (p = 0.039 respectively. The subscale of psychoticism is significantly related with the students’ origin, school, family status and semester. The subscale of neuroticism is significantly related with the students’ school. The subscale of extraversion is significantly related with the students’ family psychiatric history. Students, whose place of origin is Attica, have on average higher scores in somatization, phobic anxiety and paranoid ideation than the other students. Students from abroad have, on average, higher scores in interpersonal sensitivity and psychoticism than students who hail from other parts of Greece. The majority of the students (79.7% do not suffer from depression, according to the Beck’s depression inventory scale. Conclusions: Anxiety, somatization, personality traits and depression are related with the students’ college life.
New Measurements of the Azimuthal Alignments of Greek Temples
Mickelson, M. E.; Higbie, C.; Boyd, T. W.
1998-12-01
The canonical opinion about the placement of Greek temples is that they are oriented east-west (Dinsmoor 1975). Major exceptions, such as the temple of Apollo at Bassae which faces north-south, are always noted in the handbooks, but many other temples are scattered across the Greek landscape in a variety of orientations. Although no surviving ancient author ever discusses the criteria for placing or orienting temples, we may assume from scattered remarks that Greeks had reasons for choosing the sites and orientations. In the last century, archaeologists and architects such as Nissen (1896), Penrose (1893) and Dinsmoor (1939), have measured the alignments of Greek temples on the Greek mainland, the west coast of Turkey, and the Aegean islands. Their data have varying degrees of precision and accuracy, as a recent paper by Papathanassiou (1994) makes clear. Parallel work done in Italy on Etruscan temples by Aveni and Romano (1994) provides further stimulus to re-investigate Greek temples. We have undertaken two field seasons in Greece to make preliminary measurements for a number of temples associated with Athena, Apollo, and Zeus. These temples were chosen for a number of reasons. The structures have to be well enough preserved to allow determination of the orientation of foundations, location of doorways and other openings, placement of cult statues etc. By focusing on these three gods, we may be able to discover patterns in the orientation and placement for specific divinities. For some of these questions, we are dependent on literary and inscriptional evidence, such as the work of the Greek travel writer, Pausanias. This paper describes the preliminary measurements made over our two field seasons in Greece. Field methods and analysis of the data will be presented along with proposed applications.

We obtain a gauge-invariant relativistic quantum geometry by using a Weylian-like manifold with a geometric scalar field which provides a gauge-invariant relativistic quantum theory in which the algebra of the Weylian-like field depends on observers. An example for a Reissner–Nordström black-hole is studied.

Using only the principle of relativity and Euclidean geometry we show in this pedagogical article that the square of proper time or length in a two-dimensional spacetime diagram is proportional to the Euclidean area of the corresponding causal domain. We use this relation to derive the Minkowski line element by two geometric proofs of the spacetime Pythagoras theorem.

In recent years, I have been teaching a junior-senior-level course on the classi cal geometries. This book has grown out of that teaching experience. I assume only high-school geometry and some abstract algebra. The course begins in Chapter 1 with a critical examination of Euclid's Elements. Students are expected to read concurrently Books I-IV of Euclid's text, which must be obtained sepa rately. The remainder of the book is an exploration of questions that arise natu rally from this reading, together with their modern answers. To shore up the foundations we use Hilbert's axioms. The Cartesian plane over a field provides an analytic model of the theory, and conversely, we see that one can introduce coordinates into an abstract geometry. The theory of area is analyzed by cutting figures into triangles. The algebra of field extensions provides a method for deciding which geometrical constructions are possible. The investigation of the parallel postulate leads to the various non-Euclidean geometries. And ...
The Greeks and the Utopia: an overview through ancient Greek Literature

2009-06-01
term has an ancient Greek root but it does not exist in the vocabulary of ancient Greek language. Although ancient Greeks did not have a conscious concept of utopia, they, however, dreamt, wrote, proposed – with different aims - what we would call now ( paradoxically using a ‘modern’ term ‘utopic’ worlds. From the archaic to the post-classic period, we find literary expressions of utopic thought in ancient Greek culture. Such expressions constitute the basis of the modern Utopia and Utopianism with their positive and negative implications. This essay takes a more detailed look at the work of Aristophanes, considered one of the greatest Greek playwrights, and inquires whether his comedies can be considered utopias.

Full Text Available Since it erupted in 2009, the Greek debt crisis has disrupted Greek people’s quotidian life both at a socio-political and at a personal level. In the contemporary social media ecosystem, with the massive bulk of user-produced and user-consumed content, narratives that concern this critical turning point in Greek modern history have found fertile soil to thrive. In this article, having enmeshed discourse-centered online ethnography (Androutsopoulos, 2008 with small stories research (Georgakopoulou, 2007, the dimensional approach to narratives (Ochs & Capps, 2001, and stance-taking (Du Bois, 2007, I look at how a Greek Facebook user has recounted her emotions, thoughts, opinions, and assessments toward the Greek crisis. In doing so, I point to the intertextual, multimodal, and synergetic nature of these narratives. The article argues that Facebook can function as a powerful grassroots channel for expressive storytelling within a period of major socio-political upheaval. It also shows how Facebook has stretched our conception of what (digital storytelling is as different Facebook affordances propel into different ways of narrating within the medium.

2003-01-01
Full Text Available The paper is an overview of the results obtained up to date from the combustion and co-combustion activities with Greek brown coal in different installations, both in semi-industrial and laboratory scale. Combustion tests with Greek lignite were realized in three different Circulating Fluidized Bed Combustion (CFBC facilities. Low rank lignite was burned in a pilot scale facility of approx. 100kW thermal capacity, located in Athens (NTUA and a semi-industrial scale of 1.2 MW thermal capacity, located at RWE's power station Niederaussem in Germany. Co-combustion tests with Greek xylitic lignite and waste wood were carried out in the 1 MWth CFBC installation of AE&E, in Austria. Lab-scale co-combustion tests of Greek pre-dried lignite with biomass were accomplished in a bubbling fluidized bed in order to investigate ash melting problems. The obtained results of all aforementioned activities showed that fluidized bed is the appropriate combustion technology to efficiently exploit the low quality Greek brown coal either alone or in conjunction with biomass species.
Maternal attitudes of Greek migrant women.

1987-03-01
This study examines groups of Greek migrant mothers and their attitudes towards their children in different stages of the migratory process. There were 2 lots of samples of Greek migrants mothers who had at least 2 children 8-10 years old, 1 from the home country (5 villages of the District Drama in East Macedonia) and 1 from the receiving country (the area of Baden-Wurtenberg, where most of the migrants from East Macedonia are living). The 4 groups are: 1) 20 mothers who have always lived with their child in the host country; 2) 20 mothers who live in the host country where their child has joined them in the last 2-4 years; 3) 27 mothers who have lived in the host country with their child and have returned home in the last 2-4 years; and 4) 24 non-migrant mothers who have always lived with their families in the home country (control group). Women were interviewed using 2 questionnaires: a survey and an attitude questionnaire. The range of mothers' ages was 20-50 years. The youngest mothers were in the control group whereas group 1 mothers were the oldest. Groups 1 and 2 were mostly unskilled workers; groups 3 and 4 were mostly housewives. The returnees stayed in the host country a mean of 10 years, whereas the other 2 migrant groups were there 14.6 years. There were significantly fewer children in the families of groups 1 and 2 than 3 and 4. The attitude questionnaire covered the following child rearing practices: 1) training the child to participate in home duties; 2) keeping clean and tidy; 3) self-reliance and social behavior towards visitors; 4) ways of dealing with a child's obedience/disobedience; 5) dealing with favor-seeking behavior, food, and sleeping problems; and 6) mother's degree of permissiveness, supervision, and intervention on child's personal and interpersonal sphere of life. Findings show that moving from home to host country and coming back home creates the most controlling mothers, probably because mothers and children face anxiety
Gratiae plenum: Latin, Greek and the Cominform

Full Text Available The survival of classics in the People’s Republic of Slovenia after World War II was dominated by the long shadow of the Coryphaeus of the Sciences, Joseph Stalin. Since 1945, the profile of the discipline was determined by the Communist Party, which followed the Soviet example, well-nigh destroying the classical education in the process. Fran Bradač, head of Classics at the University of Ljubljana, was removed for political reasons; the classical gymnasium belonging to the Church was closed down; Greek was struck from the curriculum of the two remaining state classical gymnasia; Latin, previously a central subject at every gymnasium, was severely reduced in 1945, only to disappear entirely in 1946. The classicists who continued to teach were forced to take ‘reorientation courses’ which enabled them to teach Russian and other more suitable subjects. By 1949, only two out of the 42 classicists employed by the Ministry of Education were actually teaching Latin. The Classics department at the university, where only two students were studying in 1949, was on the brink of closure. Paradoxically, the classical tradition was saved by Stalin’s attack on the same Party. The Cominform conflict in 1948 astonished the Yugoslav communists and pushed them towards a tactical détente with the West, prompting a revision of some of their policies, including education. The process was led by the top echelons of the Party — such as Milovan Djilas, head of the central Agitprop, Boris Kidrič, in charge of Yugoslav economy, and Edvard Kardelj, the Party’s chief ideologue — during the Third Plenum of the Central Committee Politburo in Belgrade in December 1949. Their newly discovered love of Latin and Greek, documented in the minutes of the Politburo Plenum, was overseen only by the discriminating eye of Josip Broz Tito. Classical gymnasia were revived, Latin was reintroduced to some of the other gymnasia, students returned to study classics at the

Statistically important correlations emerged between the perceptions of executives and their socio-demographic background including age, sex, education, and profession, work experience in health-care and specifically in their current position in the services as well as statistically important differences between doctors, nurses and administrators as to their perceptions of some issues in marketing.Conclusions: From the comments in the survey it appears there is a need to apply marketing correctly when providing quality care, respecting the patients’ rights and using human and not financial criteria as a guide. Based on the results of the research, important proposals are being submitted in the areas of health-care research, education and clinical practice.
[The concept of mania in Greek medical and philosophical literature].
Corleto, L M
1992-01-01
Coverage of the concept of mania in late archaic Greek culture displays a clear difference between its use in medical and philosophical works. Medical literature uses the terms [Greek] and [Greek] to describe mania, with the condition seen largely associated with physical illness. Specific treatment for this attered psychic state is not advanced. The philosophical view sees mania as a divine folly and thus possessing positive as well as negative aspects. Plate identifies four types of mania and treatment is closely associated with the divinity seen as responsible for that particular type. The radical rationalism found in the medical literature is a counterpoint to moderation as shown by Plato with his interest on regulations of society.
Burnout syndrome indices in Greek intensive care nursing personnel.
Karanikola, Maria N K; Papathanassoglou, Elizabeth D E; Mpouzika, Meropi; Lemonidou, Chrysoula
2012-01-01
Burnout symptoms in Greek intensive care unit (ICU) nurses have not been explored adequately. The aim of this descriptive, correlational study was to investigate the prevalence and intensity of burnout symptoms in Greek ICU nursing personnel and any potential associations with professional satisfaction, as well as with demographic, educational, and vocational characteristics. Findings showed that the overall burnout level reported by Greek ICU nursing personnel was at a moderate to high degree. The most pronounced symptom of burnout was depersonalization, whereas emotional exhaustion was found to be a strong predictor of job satisfaction. This is a factor connected with the nurses' intention to quit the job. It appears that work factors have a more powerful influence over the development of burnout in comparison to personality traits.
An exploration of loyalty determinants in Greek wine varieties

Purpose - This paper aims to provide a deeper understanding of the market structure of Greek red and white wine varieties and to measure the loyalty behaviour of frequent wine buyers in Greece. Design/methodology/approach - The study measures brand performance and loyalty of four different Greek...... wine varieties. Based on stated preference data, basic brand performance measures are estimated through Juster purchase probabilities of brand choice. To measure loyalty behaviour, the polarisation index w (phi) is used as a measure to model both loyalty to the brand name and specific wine attributes...... and their levels. Findings - The findings of the present study point to the conclusion that each one of the four Greek wine varieties under examination exhibits its own market structure and loyalty profile, whereas price, quality certification and winemaker's size seem to function as loyalty stimulators more...
The art of alleviating pain in greek mythology.
Türe, Hatice; Türe, Uğur; Göğüş, F Yilmaz; Valavanis, Anton; Yaşargil, M Gazi
2005-01-01
We reviewed many of the essential Greek myths to identify the methods used at that time to relieve the pain of both illness and surgery, and we discovered many pioneering methods. Both gods and demigods implemented these methods to ease pain, to conduct surgery, and, on occasion, to kill mythological beings. The myths describe the three most common components of anesthesia: hypnosis, amnesia, and (an)algesia. Drugs and music-aided hypnosis were two of the most common methods use to treat emotional and surgical pain. This article identifies highlights in the development of concepts to treat pain in Greek mythology. The examples found in the Greek myths remind us of the historical significance of pain treatment.
Body symmetry and asymmetry in early Greek anatomical reasoning.
Crivellato, Enrico; Ribatti, Domenico
2008-05-01
This historical note focuses on some of the earliest reports of human anatomy found in Greek medical literature. These passages testify the initial steps taken by Greek scientists in building a theoretical model of the human body. In these excerpts, one finds erroneous anatomical descriptions, which shed light on the epistemological approach used by these intellectual pioneers. Because of the lack of systematic dissection, it appears that early Greek anatomists developed a somewhat stylized idea of the human body that used a certain degree of symmetry. Overcoming the concept of a strict left-right bilateral parallelism in human body architecture was a challenging intellectual task that required prolonged observation of dissected corpses.

Multivariate calculus and geometry
Dineen, Seán
2014-01-01
Multivariate calculus can be understood best by combining geometric insight, intuitive arguments, detailed explanations and mathematical reasoning. This textbook has successfully followed this programme. It additionally provides a solid description of the basic concepts, via familiar examples, which are then tested in technically demanding situations. In this new edition the introductory chapter and two of the chapters on the geometry of surfaces have been revised. Some exercises have been replaced and others provided with expanded solutions. Familiarity with partial derivatives and a course in linear algebra are essential prerequisites for readers of this book. Multivariate Calculus and Geometry is aimed primarily at higher level undergraduates in the mathematical sciences. The inclusion of many practical examples involving problems of several variables will appeal to mathematics, science and engineering students.

Multilevel geometry optimization
Rodgers, Jocelyn M.; Fast, Patton L.; Truhlar, Donald G.
2000-02-01
Geometry optimization has been carried out for three test molecules using six multilevel electronic structure methods, in particular Gaussian-2, Gaussian-3, multicoefficient G2, multicoefficient G3, and two multicoefficient correlation methods based on correlation-consistent basis sets. In the Gaussian-2 and Gaussian-3 methods, various levels are added and subtracted with unit coefficients, whereas the multicoefficient Gaussian-x methods involve noninteger parameters as coefficients. The multilevel optimizations drop the average error in the geometry (averaged over the 18 cases) by a factor of about two when compared to the single most expensive component of a given multilevel calculation, and in all 18 cases the accuracy of the atomization energy for the three test molecules improves; with an average improvement of 16.7 kcal/mol.

The recognition that the cosmological constant may be non-zero forces us to re-evaluate standard notions about the connection between geometry and the fate of our Universe. An open Universe can recollapse, and a closed Universe can expand forever. As a corollary, we point out that there is no set of cosmological observations we can perform that will unambiguously allow us to determine what the ultimate destiny of the Universe will be.

We analyse symmetry breaking in the Weinberg-Salam model paying particular attention to the underlying geometry of the theory. In this context we find two natural metrics upon the vacuum manifold: an isotropic metric associated with the scalar sector, and a squashed metric associated with the gauge sector. Physically, the interplay between these metrics gives rise to many of the non-perturbative features of Weinberg-Salam theory. (author)

The geometric structure of theories with gauge fields of spins two and higher should involve a higher spin generalisation of Riemannian geometry. Such geometries are discussed and the case of W ∝ -gravity is analysed in detail. While the gauge group for gravity in d dimensions is the diffeomorphism group of the space-time, the gauge group for a certain W-gravity theory (which is W ∝ -gravity in the case d=2) is the group of symplectic diffeomorphisms of the cotangent bundle of the space-time. Gauge transformations for W-gravity gauge fields are given by requiring the invariance of a generalised line element. Densities exist and can be constructed from the line element (generalising √detg μν ) only if d=1 or d=2, so that only for d=1,2 can actions be constructed. These two cases and the corresponding W-gravity actions are considered in detail. In d=2, the gauge group is effectively only a subgroup of the symplectic diffeomorphisms group. Some of the constraints that arise for d=2 are similar to equations arising in the study of self-dual four-dimensional geometries and can be analysed using twistor methods, allowing contact to be made with other formulations of W-gravity. While the twistor transform for self-dual spaces with one Killing vector reduces to a Legendre transform, that for two Killing vectors gives a generalisation of the Legendre transform. (orig.)
Integral geometry and valuations
Solanes, Gil
2014-01-01
Valuations are finitely additive functionals on the space of convex bodies. Their study has become a central subject in convexity theory, with fundamental applications to integral geometry. In the last years there has been significant progress in the theory of valuations, which in turn has led to important achievements in integral geometry. This book originated from two courses delivered by the authors at the CRM and provides a self-contained introduction to these topics, covering most of the recent advances. The first part, by Semyon Alesker, is devoted to the theory of convex valuations, with emphasis on the latest developments. A special focus is put on the new fundamental structures of the space of valuations discovered after Alesker's irreducibility theorem. Moreover, the author describes the newly developed theory of valuations on manifolds. In the second part, Joseph H. G. Fu gives a modern introduction to integral geometry in the sense of Blaschke and Santaló, based on the notions and tools presented...
CBM RICH geometry optimization

The Compressed Baryonic Matter (CBM) experiment at the future FAIR complex will investigate the phase diagram of strongly interacting matter at high baryon density and moderate temperatures in A+A collisions from 2-11 AGeV (SIS100) beam energy. The main electron identification detector in the CBM experiment will be a RICH detector with a CO{sub 2} gaseous-radiator, focusing spherical glass mirrors, and MAPMT photo-detectors being placed on a PMT-plane. The RICH detector is located directly behind the CBM dipole magnet. As the final magnet geometry is now available, some changes in the RICH geometry become necessary. In order to guarantee a magnetic field of 1 mT at maximum in the PMT plane for effective operation of the MAPMTs, two measures have to be taken: The PMT plane is moved outwards of the stray field by tilting the mirrors by 10 degrees and shielding boxes have been designed. In this contribution the results of the geometry optimization procedure are presented.

Geometry is one of the areas of mathematics interesting to discuss. Geometry also has a long history in mathematical developments. Therefore, it is important integrated historical development of geometry in the classroom to increase’ knowledge of how mathematicians earlier finding and constructing a geometric concept. Introduction geometrical concept can be started by introducing the Muslim mathematician who invented these concepts so that students can understand in detail how a concept of geometry can be found. However, the history of mathematics development, especially history of Islamic geometry today is less popular in the world of education in Indonesia. There are several concepts discovered by Muslim mathematicians that should be appreciated by the students in learning geometry. Great ideas of mathematicians Muslim can be used as study materials to supplement religious character values taught by Muslim mathematicians. Additionally, by integrating the history of geometry in teaching geometry are expected to improve motivation and geometrical understanding concept.
A Directed Network of Greek and Roman Mythology

We study the Greek and Roman mythology using the network theory. We construct a directed network by using a dictionary of Greek and Roman mythology in which the nodes represent the entries listed in the dictionary and we make directional links from an entry to other entries that appear in its explanatory part. We find that this network is clearly not a random network but a directed scale-free network. Also measuring the various quantities which characterize the mythology network, we analyze t...
GREEKS AND BARBARIANS IN HOMER’S “ODYSSEY”
Directory of Open Access Journals (Sweden)
Ştefania VOICU
2013-05-01
Full Text Available Homer’s “Odyssey”, viewed as a relevant literary source for Archaic Greece, has led to the development of different research domains through the medium of hermeneutics or text interpretation. One of these directions regards the reconstitution of social aspects pertaining to the Archaic Greek world. Given that Odysseus’ adventures unfold beyond the borders of the world known by the hero, Greek identity can only be rendered by exclusion, the exclusion of the Other: the reverse of the reprehensible deeds or aspects of the Other comes to define the real, or at least desirable, characteristics of the one operating the exclusion.
The nature of water: Greek thought from Homer to Acusilaos.
De Santo, Rosa Maria; Bisaccia, Carmela; Cirillo, Massimo; Pollastro, Rosa Maria; Raiola, Ilaria; De Santo, Luca Salvatore
2009-01-01
Greek philosophy finds its roots in the myth of Homer's and Hesiod's poems and especially in Orphism which introduced the concept of a soul separated from the body with an independent principle, psiche (soul), to be rewarded or punished after death. Orphism was an important step in Greek culture. It introduced the divine into man, the soul which does not die with the body and reincarnates. From Orphism started the need of rituals capable of separating the spirit from the body. From Homer to Acusilaos, water was a very important element which connected humans and gods, long before Thales of Miletus defined it the arche.
Growth, Debt and Sovereignty: Prolegomena to the Greek Crisis
Stavros B. Thomadakis
2015-01-01
The paper reflects a basic premise: Greek participation in the Euro-zone marked a definitive institutional break in the process of contracting and managing public debt. Instead of internal debt, used extensively in earlier decades, euro-denominated sovereign issues were now placed in the international market. Thus, the Greek state became a net ‘exporter’ of financial claims to an extent unprecedented in its recent history. In assessing the prolegomena to crisis, I offer a review of the post-j...

A geometric framework for quantum mechanics arose during the mid 1970s when authors such as Cantoni explored the notion of generalized transition probabilities, and Kibble promoted the idea that the space of pure quantum states provides a natural quantum mechanical analogue for classical phase space. This central idea can be seen easily since the projection of Schroedinger's equation from a Hilbert space into the space of pure spaces is a set of Hamilton's equations. Over the intervening years considerable work has been carried out by a variety of authors and a mature description of quantum mechanics in geometric terms has emerged with many applications. This current offering would seem ideally placed to review the last thirty years of progress and relate this to the most recent work in quantum entanglement. Bengtsson and Zyczkowski's beautifully illustrated volume, Geometry of Quantum States (referred to as GQS from now on) attempts to cover considerable ground in its 466 pages. Its topics range from colour theory in Chapter 1 to quantum entanglement in Chapter 15-to say that this is a whirlwind tour is, perhaps, no understatement. The use of the work 'introduction' in the subtitle of GQS, might suggest to the reader that this work be viewed as a textbook and I think that this interpretation would be incorrect. The authors have chosen to present a survey of different topics with the specific aim to introduce entanglement in geometric terms-the book is not intended as a pedagogical introduction to the geometric approach to quantum mechanics. Each of the fifteen chapters is a short, and mostly self-contained, essay on a particular aspect or application of geometry in the context of quantum mechanics with entanglement being addressed specifically in the final chapter. The chapters fall into three classifications: those concerned with the mathematical background, those which discuss quantum theory and the foundational aspects of the geometric framework, and
Functional integration over geometries
International Nuclear Information System (INIS)
Mottola, E.
1995-01-01
The geometric construction of the functional integral over coset spaces M/G is reviewed. The inner product on the cotangent space of infinitesimal deformations of M defines an invariant distance and volume form, or functional integration measure on the full configuration space. Then, by a simple change of coordinates parameterizing the gauge fiber G, the functional measure on the coset space M/G is deduced. This change of integration variables leads to a Jacobian which is entirely equivalent to the Faddeev--Popov determinant of the more traditional gauge fixed approach in non-abelian gauge theory. If the general construction is applied to the case where G is the group of coordinate reparameterizations of spacetime, the continuum functional integral over geometries, i.e. metrics modulo coordinate reparameterizations may be defined. The invariant functional integration measure is used to derive the trace anomaly and effective action for the conformal part of the metric in two and four dimensional spacetime. In two dimensions this approach generates the Polyakov--Liouville action of closed bosonic non-critical string theory. In four dimensions the corresponding effective action leads to novel conclusions on the importance of quantum effects in gravity in the far infrared, and in particular, a dramatic modification of the classical Einstein theory at cosmological distance scales, signaled first by the quantum instability of classical de Sitter spacetime. Finite volume scaling relations for the functional integral of quantum gravity in two and four dimensions are derived, and comparison with the discretized dynamical triangulation approach to the integration over geometries are discussed. Outstanding unsolved problems in both the continuum definition and the simplicial approach to the functional integral over geometries are highlighted

This excellent introduction to topology eases first-year math students and general readers into the subject by surveying its concepts in a descriptive and intuitive way, attempting to build a bridge from the familiar concepts of geometry to the formalized study of topology. The first three chapters focus on congruence classes defined by transformations in real Euclidean space. As the number of permitted transformations increases, these classes become larger, and their common topological properties become intuitively clear. Chapters 4-12 give a largely intuitive presentation of selected topics.
Torsional heterotic geometries

Becker, Katrin; Sethi, Savdeep
2009-01-01
We construct new examples of torsional heterotic backgrounds using duality with orientifold flux compactifications. We explain how duality provides a perturbative solution to the type I/heterotic string Bianchi identity. The choice of connection used in the Bianchi identity plays an important role in the construction. We propose the existence of a much larger landscape of compact torsional geometries using string duality. Finally, we present some quantum exact metrics that correspond to NS5-branes placed on an elliptic space. These metrics describe how torus isometries are broken by NS flux.

The Greek Electricity Market Reforms: Political and Regulatory Considerations
International Nuclear Information System (INIS)
Danias, Nikolaos; Kim Swales, John; McGregor, Peter
2013-01-01
The paper tracks the evolution of the Greek electricity market since the beginning of the liberalization process. Its progress is benchmarked against the criteria suggested by Littlechild (2006b). The Littlechild framework highlights key remaining deficiencies in the stances and policies adopted which need to be resolved in order for liberalization to proceed successfully. The focus is on the agendas of the Greek government, other domestic political forces and the European Union. A central requirement is the clear commitment to liberalization by the Greek government. In particular the government needs to give up political control over the previous vertically integrated, state-controlled electricity firm, Public Power Company (PPC), and allow more decision making powers and genuine independence to the market regulator. Liberalization is rendered more difficult by the present financial and economic crisis in Greece. - Highlights: • Greek electricity market liberalization is benchmarked against the Littlechild standard electricity market reform model. • Although the majority of the model requirements are met, liberalization in Greece is only partially successful. • Some elements of liberalization are qualitatively more significant than others. • More fundamental political economy issues need to be addressed in order for the liberalization to progress. • Financial crisis in Greece adds extra challenges

Panagiotis Dimitropoulos
2010-01-01
Full Text Available The aim of this paper is to analyze the financial performance of the football clubs participating within the first division of the Greek football league for a period of 14 years (1993-2006 and to propose specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs. We perform financial analysis of key accounting ratios extracted from the football club’s annual financial statements in order to explain the particular causes of the recent financial crisis which characterizes the Greek professional football league. The analysis of the clubs’ annual financial statements revealed that the Greek football clubs are highly leveraged, have intense liquidity and profitability problems and face an increased danger of financial distress, despite the increased amounts that football clubs invested during 2005. The above mentioned crisis can be attributed to aggregate financial mismanagement and political inefficiencies during the last fifteen years. The paper proposes specific actions that need to be taken by both managers and regulators in order to improve the financial stability of the clubs and the overall competitiveness of the Greek football league.

On the acoustics of ancient Greek and Roman theaters.
Farnetani, Andrea; Prodi, Nicola; Pompoli, Roberto
2008-09-01
The interplay of architecture and acoustics is remarkable in ancient Greek and Roman theaters. Frequently they are nowadays lively performance spaces and the knowledge of the sound field inside them is still an issue of relevant importance. Even if the transition from Greek to Roman theaters can be described with a great architectural detail, a comprehensive and objective approach to the two types of spaces from the acoustical point of view is available at present only as a computer model study [P. Chourmouziadou and J. Kang, "Acoustic evolution of ancient Greek and Roman theaters," Appl. Acoust. 69, re (2007)]. This work addresses the same topic from the experimental point of view, and its aim is to provide a basis to the acoustical evolution from Greek to Roman theater design. First, by means of in situ and scale model measurements, the most important features of the sound field in ancient theaters are clarified and discussed. Then it has been possible to match quantitatively the role of some remarkable architectural design variables with acoustics, and it is seen how this criterion can be used effectively to define different groups of ancient theaters. Finally some more specific wave phenomena are addressed and discussed.

The main characteristics of fly ash from Greek coal-fired boilers are presented in this paper in relation to its exploitation potential. Both fuel and fly ash samples were collected and analyzed according to the ASTM Standards. Apart from the typical analyses (proximate, ultimate, ash analysis and calorific value), an ICP-AES spectrometer was used for the analysis of heavy metals in the ash. Experimental measurements in order to determine the radioactivity content of raw fuel and the fly ash were carried out as well. A representative fly ash sample from Ptolemais power plant was evaluated and tested as filler in Self-Compacting Concrete (SCC). Ashes from the Greek brown coal are classified in type C, most of the fly ash being produced in Ptolemais of Northern Greece, while the rest in Megalopolis. Ptolemais fly ash is rich in calcium compounds, while Megalopolis fly ash contains more pyrite. Increased heavy metal concentrations are observed in the fly ash samples of Greek coal. Greek fly ash appears to have not only pozzolanic but also hydraulic behaviour. Furthermore, Greek fly ash, depending on its origin, may have relatively high natural radioactivity content, reaching in the case of Megalopolis fly ash 1 kBq kg{sup -1} of {sup 226}Ra. The laboratory results showed that fly ashes can be a competitive substitute to conventional limestone filler material in SCC. Fly ash is mostly used in Greece in cement industry replacing cement clinker and aiming to the production of special types of Portland cements. However, a more aggressive utilisation strategy should be developed, since low quantities of the total produced fly ash are currently further utilised. (author)
Alchemy, Chinese versus Greek, an etymological approach: a rejoinder.
Mahdihassan, S
1988-01-01
The theory generally accepted maintains that Alchemy arose at Alexandria as a child of Greek culture. It has two names, Chemeia as the earlier and Chumeia as the later. There is another theory that Alchemy arose in China. Its founder was the aged ascetic who longed after drugs of longevity. He first tried jade, next gold and cinnabar, but the ideal was a drug which was red like cinnabar and fire-proof like gold. But what was actually prepared was red colloidal gold or "calcined gold," by grinding gold granules in a decoction of an herb of longevity. It was called Chin-I; Chin = gold and I = plant juice. In Fukin dialect Chin-I = Kim-Iya. This was Arabicized, by pre-Islamic Arabs trading in silk with China, as Kimiya, whence arose Al-Kimiya and finally Al-chemy. It was first accepted by Bucharic speaking Copts in Egypt who transliterated Kimiya = Chemeia, pronouncing it as the Arabs did. With the increase of trade in silk the Chinese also went to Alexandria and helped the Greeks to translate Chin-I as Chrusozomion meaning, gold (making) ferment, instead of gold making plant juice. Consistent with this origin of the word Chemeia is the fact that the earlier Alchemists were not Greeks but probably Bucharic speaks Copts or Egyptians. The consumer of Chin-I or Chemeia became "a drug-made immortal" called Chin-Jen, Golden-Man. This was translated into Greek as Chrusanthropos. Thus the etymoloogy of two Greek words Chrusozomion and Chrusanthropos support the origin of the loan word, Chemeia as Chinese. To save space it is not proposed to discuss the origin of Chumeia.

The Metacognitions Questionnaire-30 (MCQ-30), developed by Wells and Cartwright-Hatton (2004), represents a multidimensional measure of metacognitive factors considered to be important in the metacognitive model of psychological disorders. The primary aim of the present study was to examine internal consistency, test-retest reliability, convergent validity and the factor structure of the Greek version of the MCQ-30. Moreover, we investigated the associations of the extracted factors with trait anxiety in a Greek sample. The study sample consisted of 547 non-clinical participants (213 males and 334 females). All participants completed the Greek version of the MCQ-30. A subsample of 157 participants also completed the Trait Anxiety subscale of the State -Trait Anxiety Inventory and the Meta-worry subscale of the Anxious Thought Inventory. Thirty participants were retested with the MCQ-30 over a retest interval ranging from three to five weeks. The results confirmed the dimensionality of the MCQ-30 and five factors were extracted consistent with the original English version: (1) positive beliefs about worry, (2) negative beliefs about worry concerning uncontrollability and danger, (3) cognitive confidence, (4) beliefs about the need to control thoughts and the negative consequences of not controlling them, and (5) cognitive selfconsciousness. The MCQ-30 showed high levels of internal consistency and test-retest reliability. The correlation between MCQ-30 total score and AnTI-MW was strong, indicating high level of convergent validity. Moreover, all correlations between MCQ-30 total and subscale scores and STAI-T were significant apart from the correlation between 'cognitive confidence' and trait anxiety. The Greek sample scored higher in the MCQ-30 and its subscales than the English sample in the original study. Women scored significantly higher than men in the overall MCQ-30 and the "uncontrollability and danger" and "need to control thoughts" subscales, whereas no

This book is a systematic treatment of real algebraic geometry, a subject that has strong interrelation with other areas of mathematics: singularity theory, differential topology, quadratic forms, commutative algebra, model theory, complexity theory etc. The careful and clearly written account covers both basic concepts and up-to-date research topics. It may be used as text for a graduate course. The present edition is a substantially revised and expanded English version of the book "Géometrie algébrique réelle" originally published in French, in 1987, as Volume 12 of ERGEBNISSE. Since the publication of the French version the theory has made advances in several directions. Many of these are included in this English version. Thus the English book may be regarded as a completely new treatment of the subject.
Critique of information geometry
International Nuclear Information System (INIS)
Skilling, John
2014-01-01
As applied to probability, information geometry fails because probability distributions do not form a metric space. Probability theory rests on a compelling foundation of elementary symmetries, which also support information (aka minus entropy, Kullback-Leibler) H(p;q) as the unique measure of divergence from source probability distribution q to destination p. Because the only compatible connective H is from≠to asymmetric, H(p;q)≠H(q;p), there can be no compatible geometrical distance (which would necessarily be from=to symmetric). Hence there is no distance relationship compatible with the structure of probability theory. Metrics g and densities sqrt(det(g)) interpreted as prior probabilities follow from the definition of distance, and must fail likewise. Various metrics and corresponding priors have been proposed, Fisher's being the most popular, but all must behave unacceptably. This is illustrated with simple counter-examples

We discuss how geometrical and topological aspects of certain (1/2)-BPS type IIB geometries are captured by their dual operators in N = 4 Super Yang-Mills theory. The type IIB solutions are characterized by arbitrary droplet pictures in a plane and we consider, in particular, axially symmetric droplets. The 1-loop anomalous dimension of the dual gauge theory operators probed with single traces is described by some bosonic lattice Hamiltonians. These Hamiltonians are shown to encode the topology of the droplets. In appropriate BMN limits, the Hamiltonians spectrum reproduces the spectrum of near-BPS string excitations propagating along each of the individual edges of the droplet. We also study semiclassical regimes for the Hamiltonians. For droplets having disconnected constituents, the Hamiltonian admits different complimentary semiclassical descriptions, each one replicating the semiclassical description for closed strings extending in each of the constituents

In work http://dx.doi.org/10.1103/PhysRevD.86.086001, a surface embedded in flat ℝ{sup 3} is associated to any three hermitian matrices. We study this emergent surface when the matrices are large, by constructing coherent states corresponding to points in the emergent geometry. We find the original matrices determine not only shape of the emergent surface, but also a unique Poisson structure. We prove that commutators of matrix operators correspond to Poisson brackets. Through our construction, we can realize arbitrary noncommutative membranes: for example, we examine a round sphere with a non-spherically symmetric Poisson structure. We also give a natural construction for a noncommutative torus embedded in ℝ{sup 3}. Finally, we make remarks about area and find matrix equations for minimal area surfaces.
Geometry through history Euclidean, hyperbolic, and projective geometries
Dillon, Meighan I
2018-01-01
Presented as an engaging discourse, this textbook invites readers to delve into the historical origins and uses of geometry. The narrative traces the influence of Euclid’s system of geometry, as developed in his classic text The Elements, through the Arabic period, the modern era in the West, and up to twentieth century mathematics. Axioms and proof methods used by mathematicians from those periods are explored alongside the problems in Euclidean geometry that lead to their work. Students cultivate skills applicable to much of modern mathematics through sections that integrate concepts like projective and hyperbolic geometry with representative proof-based exercises. For its sophisticated account of ancient to modern geometries, this text assumes only a year of college mathematics as it builds towards its conclusion with algebraic curves and quaternions. Euclid’s work has affected geometry for thousands of years, so this text has something to offer to anyone who wants to broaden their appreciation for the...
On organizing principles of discrete differential geometry. Geometry of spheres
International Nuclear Information System (INIS)
Bobenko, Alexander I; Suris, Yury B
2007-01-01
Discrete differential geometry aims to develop discrete equivalents of the geometric notions and methods of classical differential geometry. This survey contains a discussion of the following two fundamental discretization principles: the transformation group principle (smooth geometric objects and their discretizations are invariant with respect to the same transformation group) and the consistency principle (discretizations of smooth parametrized geometries can be extended to multidimensional consistent nets). The main concrete geometric problem treated here is discretization of curvature-line parametrized surfaces in Lie geometry. Systematic use of the discretization principles leads to a discretization of curvature-line parametrization which unifies circular and conical nets.

An introduction to incidence geometry
De Bruyn, Bart
2016-01-01
This book gives an introduction to the field of Incidence Geometry by discussing the basic families of point-line geometries and introducing some of the mathematical techniques that are essential for their study. The families of geometries covered in this book include among others the generalized polygons, near polygons, polar spaces, dual polar spaces and designs. Also the various relationships between these geometries are investigated. Ovals and ovoids of projective spaces are studied and some applications to particular geometries will be given. A separate chapter introduces the necessary mathematical tools and techniques from graph theory. This chapter itself can be regarded as a self-contained introduction to strongly regular and distance-regular graphs. This book is essentially self-contained, only assuming the knowledge of basic notions from (linear) algebra and projective and affine geometry. Almost all theorems are accompanied with proofs and a list of exercises with full solutions is given at the end...

Casimir interactions are interactions induced by quantum vacuum fluctuations and thermal fluctuations of the electromagnetic field. Using a path integral quantization for the gauge field, an effective Gaussian action will be derived which is the starting point to compute Casimir forces between macroscopic objects analytically and numerically. No assumptions about the independence of the material and shape dependent contributions to the interaction are made. We study the limit of flat surfaces in further detail and obtain a concise derivation of Lifshitz' theory of molecular forces. For the case of ideally conducting boundaries, the Gaussian action will be calculated explicitly. Both limiting cases are also discussed within the framework of a scalar field quantization approach, which is applicable for translationally invariant geometries. We develop a non-perturbative approach to calculate the Casimir interaction from the Gaussian action for periodically deformed and ideally conducting objects numerically. The obtained results reveal two different scaling regimes for the Casimir force as a function of the distance between the objects, their deformation wavelength and -amplitude. The results confirm that the interaction is non-additive, especially in the presence of strong geometric deformations. Furthermore, the numerical approach is extended to calculate lateral Casimir forces. The results are consistent with the results of the proximity-force approximation for large deformation wavelengths. A qualitatively different behaviour between the normal and lateral force is revealed. We also establish a relation between the boundary induced change of the of the density of states for the scalar Helmholtz equation and the Casimir interaction using the path integral method. For statically deformed boundaries, this relation can be expressed as a novel trace formula, which is formally similar to the so-called Krein-Friedel-Lloyd formula. While the latter formula describes the
Planetary Image Geometry Library
Deen, Robert C.; Pariser, Oleg
2010-01-01
The Planetary Image Geometry (PIG) library is a multi-mission library used for projecting images (EDRs, or Experiment Data Records) and managing their geometry for in-situ missions. A collection of models describes cameras and their articulation, allowing application programs such as mosaickers, terrain generators, and pointing correction tools to be written in a multi-mission manner, without any knowledge of parameters specific to the supported missions. Camera model objects allow transformation of image coordinates to and from view vectors in XYZ space. Pointing models, specific to each mission, describe how to orient the camera models based on telemetry or other information. Surface models describe the surface in general terms. Coordinate system objects manage the various coordinate systems involved in most missions. File objects manage access to metadata (labels, including telemetry information) in the input EDRs and RDRs (Reduced Data Records). Label models manage metadata information in output files. Site objects keep track of different locations where the spacecraft might be at a given time. Radiometry models allow correction of radiometry for an image. Mission objects contain basic mission parameters. Pointing adjustment ("nav") files allow pointing to be corrected. The object-oriented structure (C++) makes it easy to subclass just the pieces of the library that are truly mission-specific. Typically, this involves just the pointing model and coordinate systems, and parts of the file model. Once the library was developed (initially for Mars Polar Lander, MPL), adding new missions ranged from two days to a few months, resulting in significant cost savings as compared to rewriting all the application programs for each mission. Currently supported missions include Mars Pathfinder (MPF), MPL, Mars Exploration Rover (MER), Phoenix, and Mars Science Lab (MSL). Applications based on this library create the majority of operational image RDRs for those missions. A

Full Text Available Precise quantification of the profile of egg can provide a powerful tool for the analysis of egg shape for various biological problems. A new approach to the geometry of a Ostrich’s egg profile is presented here using an analysing the egg’s digital photo by edge detection techniques. The obtained points on the eggshell counter are fitted by the Fourier series. The obtained equations describing an egg profile have been used to calculate radii of curvature. The radii of the curvature at the important point of the egg profile (sharp end, blunt end and maximum thickness are independent on the egg shape index. The exact values of the egg surface and the egg volume have been obtained. These quantities are also independent on the egg shape index. These quantities can be successively estimated on the basis of simplified equations which are expressed in terms of the egg length, L¸ and its width, B. The surface area of the eggshells also exhibits good correlation with the egg long circumference length. Some limitations of the most used procedures have been also shown.

Using the self-dual representation of quantum general relativity, based on Ashtekar's new phase space variables, we present an infinite dimensional family of quantum states of the gravitational field which are exactly annihilated by the hamiltonian constraint. These states are constructed from Wilson loops for Ashtekar's connection (which is the spatial part of the left handed spin connection). We propose a new regularization procedure which allows us to evaluate the action of the hamiltonian constraint on these states. Infinite linear combinations of these states which are formally annihilated by the diffeomorphism constraints as well are also described. These are explicit examples of physical states of the gravitational field - and for the compact case are exact zero eigenstates of the hamiltonian of quantum general relativity. Several different approaches to constructing diffeomorphism invariant states in the self dual representation are also described. The physical interpretation of the states described here is discussed. However, as we do not yet know the physical inner product, any interpretation is at this stage speculative. Nevertheless, this work suggests that quantum geometry at Planck scales might be much simpler when explored in terms of the parallel transport of left-handed spinors than when explored in terms of the three metric.

A comparison of education in Greek and English nurses.
Bakalis, N A; Bowman, G S; Porock, D
2004-06-01
Curriculum is an important component of nurse education and is thought to vary from country to country. To determine the level of cardiac knowledge in Greek and English final-year student nurses. Subjects were final-year diploma and degree student nurses (n = 161) from Greece and England. Pictographs (testing knowledge in a pictorial form) were used as a method of data collection. Three anatomical cardiac diagrams were used. Students were asked to label 20 anatomical parts. Final-year English student nurses have better knowledge in the discrete area of cardiac anatomy and physiology (P nurses from different countries. The findings of the study are important because they show differences in anatomical knowledge levels between Greek and English students. More research is needed to explore further different levels of knowledge and education within the European Union and the consequences for nurse decision-making and patient outcomes.
Option's value - Greek measures fluctuations and their consequences

2004-01-01
Full Text Available Options are financial instruments that can be applied in many situations. Options buyers sell risk which is bought by their sellers who are obliged to reduce it as much as possible. It can be done by using hedging strategies based on Greek letters and options values analysis. The author proves that Greek letters are not constant during the time of option’s life. The paper shows to what extent they are influenced by such factors as risk free interest rate, volatility, underlying asset price and time to maturity. The conclusion is that options sellers must play an active role, i.e. follow fluctuations of all these parameters and modify their hedging portfolios regularly.
Natural desulfurization in coal-fired units using Greek lignite.
Konidaris, Dimitrios N
2010-10-01
This paper analyzes the natural desulfurization process taking place in coal-fired units using Greek lignite. The dry scrubbing capability of Greek lignite appears to be extremely high under special conditions, which can make it possible for the units to operate within the legislative limits of sulfur dioxide (SO2) emissions. According to this study on several lignite-fired power stations in northern Greece, it was found that sulfur oxide emissions depend on coal rank, sulfur content, and calorific value. On the other hand, SO2 emission is inversely proportional to the parameter gammaCO2(max), which is equal to the maximum carbon dioxide (CO2) content by volume of dry flue gas under stoichiometric combustion. The desulfurization efficiency is positively correlated to the molar ratio of decomposed calcium carbonate to sulfur and negatively correlated to the free calcium oxide content of fly ash.
The breast: from Ancient Greek myths to Hippocrates and Galen.
Iavazzo, C R; Trompoukis, C; Siempos, I I; Falagas, M E
2009-01-01
This is a historical article about Ancient Greek literature from mythological times until the first centuries AD with regard to the female breast. We endeavoured to collect several elegant narratives on the topic as well as to explore the knowledge of Ancient Greek doctors on the role, physiology and pathology of breast and the treatment of its diseases. We identified such descriptions in myths regarding Amazons, Hercules, Zeus, Hera and Amaltheia. Furthermore, descriptions on the topic were also found in the work of Hippocrates, Aristoteles, Soranos, Alexander of Aphrodisias, Celsus, Archigenis, Leonides, Galen and Oribasius. We may conclude that some of today's medical knowledge or practice regarding the breast was also known in the historical period.
The evolution of Greek fauna since classical times
Directory of Open Access Journals (Sweden)
Konstantinos Sidiropoulos
2017-02-01
Full Text Available This article concerns the Greek fauna of classical and late antiquity and changes up to the present day. The main sources for the fauna of antiquity are historical, geographical and zoological texts, as well as descriptions from travellers who visited Greece. The study of the texts of classical and late antiquity was based on the following classical authors: Xenophon, Aristotle, Aristophanes Byzantios, Pliny, Dio Chrysostom, Plutarch, Pausanias and Aelian. Some species that were present in the Greek fauna of classical and late antiquity, such as the lion and the leopard, are today extinct in Greece, whereas some other species that are now common, such as the cat, the chicken and the peacock, were introduced about that time or a little earlier from other regions. Some other species that are also common today, such as the wild rabbit and the pheasant, were unknown at that time, as they appeared later in Greece from other areas.
Adolescents' mental health and the Greek family: preventive aspects.
Ierodiakonou, C S
1988-03-01
Preventive mental health measures can be properly planned only if the various factors leading to the adolescent's personality structure are extensively investigated. Starting with the specific attitudes of a couple towards genetic counselling, the disadvantages of urbanization and of the dissolution of the traditional extended family are discussed with regard to their effect on the younger members. Data are produced concerning the child-rearing practices of Greek in comparison to American parents and their effect on the adolescent's emotional life. Extreme dependence on the family, pressure for school achievements, lack of sexual education, etc. are characteristic of the stresses a Greek adolescent undergoes. Socio-cultural conditions, like immigration, adoption, etc. are shown to have a different psychological effect on an adolescent in Greece than in America. Specific stresses regarding the adolescent's future, like preparing for university entrance examinations, are discussed and preventive measures are proposed.
The Invention of Infertility in the Classical Greek World:
Flemming, Rebecca
2013-01-01
Summary The article examines the understandings of, and responses to, reproductive failure in the classical Greek world. It discusses explanations and treatments for non-procreation in a range of ancient Greek medical texts, focusing on the writings of the Hippocratic Corpus, which devote considerable energy to matters of fertility and generation, and places them alongside the availability of a divine approach to dealing with reproductive disruption, the possibility of asking various deities, including the specialist healing god Asclepius, for assistance in having children. Though the relations between these options are complex, they combine to produce a rich remedial array for those struggling with childlessness, the possibility that any impediment to procreation can be removed. Classical Greece, rather than the nineteenth century, or even 1978, is thus the time when “infertility,” understood as an essentially reversible somatic state, was invented. PMID:24362276
Workplace Bullying Among the Nursing Staff of Greek Public Hospitals.
Karatza, Christine; Zyga, Sofia; Tziaferi, Styliani; Prezerakos, Panagiotis
2017-02-01
In this quantitative, cross-sectional study, the authors identified the impact of workplace bullying on nursing staff employed at select Greek public hospitals. They conducted the study using the Negative Acts Questionnaire with a convenience sample of 841 participants employed by five Greek hospitals in the 1st Regional Health Authority of Attica. One third of the respondents reported having been psychologically harassed at work in the past 6 months. According to the results, the impact workplace bullying has on nursing staff varies depending on the existence of a supportive familial or friend environment and if nurses parent children. These findings demonstrate the value of family and friend support when coping with workplace bullying.
Hyman Minsky's financial instability hypothesis and the Greek debt crisis
Directory of Open Access Journals (Sweden)
Sergey Beshenov
2015-12-01
Full Text Available This article attempts to analyze the current debt crisis in Greece based on the financial instability hypothesis developed by Hyman Minsky. This article shows that the hypothesis provides an understanding of how an economy endogenously becomes “financially fragile” and thus prone to crises. The authors analyze how public and private sector behavior in the Greek economy led to the country's debt crisis. In particular, based on a sample of 36 Greek companies, the authors show that between 2001 and 2014, the majority of those companies had switched to fragile financial structures. Special attention is devoted to the negative consequences of applying the neoclassical doctrine of “austerity measures” in Greece as the principal “anti-crisis” concept of mainstream economic science.
Autonomy and job satisfaction for a sample of Greek teachers.
Koustelios, Athanasios D; Karabatzaki, Despina; Kousteliou, Ioanna
2004-12-01
Analysing the relation between Job Satisfaction and Autonomy in a sample of 300 Greek teachers (114 men and 186 women, 28 to 59 years old) from primary and secondary schools, showed statistically significant positive correlations between Job Satisfaction and Autonomy. Particularly, Autonomy was correlated with Job Itself (.21), Supervision (.22), and the Organizational as a Whole (.27), aspects of Job Satisfaction. Findings are in line with previous studies conducted in different cultural contexts. Percent common variance accounted for is small.

Full Text Available Primary care physicians face challenges in diagnosing and managing gastroesophageal reflux disease (GERD. The Reflux Disease Questionnaire (RDQ meets the standards of validity, reliability, and practicability. This paper reports on the validation of the Greek translation of the RDQ. RDQ is a condition specific instrument. For the validation of the questionnaire, the internal consistency of its items was established using the alpha coefficient of Chronbach. The reproducibility (test-retest reliability was measured by kappa correlation coefficient and the criterion of validity was calculated against the diagnosis of another questionnaire already translated and validated into Greek (IDGP using kappa correlation coefficient. A factor analysis was also performed. Greek RDQ showed a high overall internal consistency (alpha value: 0.91 for individual comparison. All 8 items regarding heartburn and regurgitation, GERD, had good reproducibility (Cohen’s κ 0.60-0.79, while the remaining 4 items about dyspepsia had a moderate reproducibility (Cohen’s κ=’ 0.40-0.59 The kappa coefficient for criterion validity for GERD was rather poor (0.20, 95% CI: 0.04, 0.36 and the overall agreement between the results of the RDQ questionnaire and those based on the IDGP questionnaire was 70.5%. Factor analysis indicated 3 factors with Eigenvalue over 1.0, and responsible for 76.91% of variance. Regurgitation items correlated more strongly with the third component but pain behind sternum and upper stomach pain correlated with the second component. The Greek version of RDQ seems to be a reliable and valid instrument following the pattern of the original questionnaire, and could be used in primary care research in Greece.
Uterine cancer in the writings of ancient Greek physicians.
Tsoucalas, Gregory; Karamanou, Marianna; Sgantzos, Markos; Deligeoroglou, Efthimios; Androutsos, George
2015-01-01
In this article, we present the views on uterine cancer of the ancient Greek physicians. We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative.

Mary Beard
2010-06-01
Full Text Available This essay offers a critique of Ernst Gombrich’s account of the Greek Revolution. I hope to show, however, that three major pivots of his argument -- the initiating rôle of the narrative, the continuing process of the refinement of "realism" and the breakdown of that process in the late Roman Empire cannot bear the weight assigned to them. On careful examination Gombrich's delicately balanced argument, with its artful rhetoric, collapses.

Greek mathematical thought and the origin of algebra
Klein, Jacob
1992-01-01
Important study focuses on the revival and assimilation of ancient Greek mathematics in the 13th-16th centuries, via Arabic science, and the 16th-century development of symbolic algebra. This brought about the crucial change in the concept of number that made possible modern science - in which the symbolic ""form"" of a mathematical statement is completely inseparable from its ""content"" of physical meaning. Includes a translation of Vieta's Introduction to the Analytical Art. 1968 edition. Bibliography.

Connectivity Practices and Activity of Greek Political Blogs
Directory of Open Access Journals (Sweden)
Kostas Zafiropoulos
2012-08-01
Full Text Available This paper uses Social Network Analysis indexes to study Greek political blogs. The indexes describe bloggers’ community recommendations, centrality and bloggers’ attempt to form spheres of influence. Five Social Network Analysis indexes are used: incoming links, normalized betweenness, outgoing links, number of 1-cliques a blog belongs to, and size of blog’s ego-network. By recording 127 Greek political blogs, the paper finds that there are two distinct blog performance properties regarding connectivity: Only a few blogs serve as authority blogs having many incoming links and centrality, while a few others try to expand their influence territory by having many outgoing links and forming larger 1-cliques and ego-networks. Next, the paper associates the proposed indexes with blogs’ and users’ community activity. Authority blogs present high blog activity and users’ community activity, as well. These are recorded by large numbers of posts and comments to the blog posts, respectively. It is shown that blogs, which strive to expand their network by using many outgoing links are more likely to link to the authority blogs. Content analysis reveals that authority blogs provide news and information and promote discussion to a much higher degree compared to the overall Greek political blogosphere.
Greek mythology: the eye, ophthalmology, eye disease, and blindness.
Trompoukis, Constantinos; Kourkoutas, Dimitrios
2007-06-01
In distant eras, mythology was a form of expression used by many peoples. A study of the Greek myths reveals concealed medical knowledge, in many cases relating to the eye. An analysis was made of the ancient Greek texts for mythological references relating to an understanding of vision, visual abilities, the eye, its congenital and acquired abnormalities, blindness, and eye injuries and their treatment. The Homeric epics contain anatomical descriptions of the eyes and the orbits, and an elementary knowledge of physiology is also apparent. The concept of the visual field can be seen in the myth of Argos Panoptes. Many myths describe external eye disease ("knyzosis"), visual disorders (amaurosis), and cases of blinding that, depending on the story, are ascribed to various causes. In addition, ocular motility abnormalities, congenital anomalies (cyclopia), injuries, and special treatments, such as the "licking" method, are mentioned. The study of mythological references to the eye reveals reliable medical observations of the ancient Greeks, which are concealed within the myths.
Minimising generation of acid whey during Greek yoghurt manufacturing.
Uduwerella, Gangani; Chandrapala, Jayani; Vasiljevic, Todor
2017-08-01
Greek yoghurt, a popular dairy product, generates large amounts of acid whey as a by-product during manufacturing. Post-processing treatment of this stream presents one of the main concerns for the industry. The objective of this study was to manipulate initial milk total solids content (15, 20 or 23 g/100 g) by addition of milk protein concentrate, thus reducing whey expulsion. Such an adjustment was investigated from the technological standpoint including starter culture performance, chemical and physical properties of manufactured Greek yoghurt and generated acid whey. A comparison was made to commercially available products. Increasing protein content in regular yoghurt reduced the amount of acid whey during whey draining. This protein fortification also enhanced the Lb. bulgaricus growth rate and proteolytic activity. Best structural properties including higher gel strength and lower syneresis were observed in the Greek yoghurt produced with 20 g/100 g initial milk total solid compared to manufactured or commercially available products, while acid whey generation was lowered due to lower drainage requirement.

Diabetes knowledge has been shown to improve glycemic control and associate with several demographic parameters. In Greece, a country with high obesity rates, disease knowledge has never been evaluated in diabetic patients. This cross sectional study aimed to assess diabetes knowledge and its associations between social and demographic parameters, among Greek type 2 diabetes mellitus (T2DM) patients. One hundred fifty nine patients with T2DM were recruited from an urban and a rural clinic in Greece. Diabetes knowledge was assessed with the Brief Diabetes Knowledge Test (DKT). Basic anthropometry was performed. Data regarding glycemic control and sociodemographic characteristics were collected from the patients' medical files. Greek T2DM patients demonstrated poor disease knowledge (mean DKT score 8.3±2.2/14.0 and mean DKT as a percent of correct answers 59.6±15.8%). No differences were observed between sex, place of residence, or glycemic control, among subjects. Patients with higher education demonstrated greater diabetes knowledge. Simple obesity with concurrent central obesity or suboptimal glycemic control decreased diabetes knowledge among participants. Additionally, waist circumference was inversely correlated to diabetes knowledge. Based on the DKT, Greek patients exhibit poor diabetes knowledge. This study provides evidence for the need for better diabetes education in order to ameliorate disease outcome. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.
Greek Immigrants in Australia: Implications for Culturally Sensitive Practice.
Georgiades, Savvas Daniel
2015-10-01
This exploratory research examined adjustment challenges, resiliencies, attitudes, emotional health, economic stability, criminal involvement, victimization and service experiences, and some cultural propensities of Greek Immigrants (GIs) in Australia using a convenient multi-generational sample (n = 123; response rate = .5). Data were collected via surveys, telephone, and personal-interviews in four major Australian cities. Among other things, the study revealed that Greek identity and cultural customs are often significant to first generation GIs. Adjustment challenges upon entry include primarily language, housing, and transportation difficulties, nostalgia for relatives and the motherland, unfamiliarity with socio-cultural systems, unemployment, money challenges, and lack of friendships. Christian faith, the extended family, family values and traditions, cultural pride for ancient Greek achievements, and a hard 'work ethic' are notable resiliencies that support GIs in their struggles and solidify their pursuit for happiness and success. Financial concerns, aging, and nostalgia for relatives and the motherland were the primary causes of socio-emotional instability. Attitudinal differences in the respondents based on age, gender, and socio-economic status, cross-cultural comparisons, and recommendations for culturally-sensitive practice with GIs are analyzed and methodological limitations illuminated. Future research needs in the field are also highlighted.

Shafarevich Basic Algebraic Geometry 2 The second edition of Shafarevich's introduction to algebraic geometry is in two volumes. The second volume covers schemes and complex manifolds, generalisations in two different directions of the affine and projective varieties that form the material of the first volume. Two notable additions in this second edition are the section on moduli spaces and representable functors, motivated by a discussion of the Hilbert scheme, and the section on Kähler geometry. The book ends with a historical sketch discussing the origins of algebraic geometry. From the Zentralblatt review of this volume: "... one can only respectfully repeat what has been said about the first part of the book (...): a great textbook, written by one of the leading algebraic geometers and teachers himself, has been reworked and updated. As a result the author's standard textbook on algebraic geometry has become even more important and valuable. Students, teachers, and active researchers using methods of al...

In a recent paper (Jonsson and Westman 2006 Class. Quantum Grav. 23 61), a generalization of optical geometry, assuming a non-shearing reference congruence, is discussed. Here we illustrate that this formalism can be applied to (a finite four-volume) of any spherically symmetric spacetime. In particular we apply the formalism, using a non-static reference congruence, to do optical geometry across the horizon of a static black hole. While the resulting geometry in principle is time dependent, we can choose the reference congruence in such a manner that an embedding of the geometry always looks the same. Relative to the embedded geometry the reference points are then moving. We discuss the motion of photons, inertial forces and gyroscope precession in this framework

Full Text Available This article is devoted to the problem of the value orientations of modern young people, who begin their independent life in the current conditions of the difficult changes in the political, social and economic life of the countries. Greece and Russia are two of the countries, which are in crisis due to the globalisation processes. The article gives the details of the results of the empirical study of the value orientations in Greek and Russian students and presents their comparative analysis. It identifies the similarity of the value orientations in Greek and Russian students, which appears in the fact that the value of health (it seems quite difficult to achieve and the value of self-development and self-improvement (an easily achievable value are important to the students of both groups; and the values of creativity and financially-secure life (the value, which is difficult to achieve have little significance. The significant differences between the groups lie in the fact, that the Russian group is dominated by the people with the focus on business, the value of interesting work is important to them, they are more focused on business activity, as well as on love, and the interpersonal relations are less significant for them. The Greek students are often focused on themselves, on their families; freedom in actions, confidence and friendship are more important to them. The peculiarities of the value orientations of the Russian students are internally more conflicting: first of all, we are talking of an important value of love and its dissatisfaction, the important value of an interesting job and the idea that it is difficult to achieve these values. The internal conflict of the Greek students often concerns the importance and the low availability of the value of freedom. The study shows that the peculiarities of the value orientations of Russian students reflect the socio-economic changes in the society, while the values of Greek students

Full Text Available Several studies have explored the acoustic structure of fricatives, yet there has been very little acoustic research on the effects of dialects on the production of fricatives. This article investigates the effects of two linguistically proximal Modern Greek dialects, Athenian Greek and Cypriot Greek on the temporal, spectral, and coarticulatory properties of fricatives and aims to determine the acoustic properties that convey information about these two dialects. Productions of voiced and voiceless labiodental, dental, alveolar, palatal, and velar fricatives were extracted from a speaking task from typically speaking female adult speakers (25 Cypriot Greek and 20 Athenian Greek speakers. Measures were made of spectral properties, using a spectral moments analysis. The formants of the following vowel were measured and second degree polynomials of the formant contours were calculated. The findings showed that Athenian Greek and Cypriot Greek fricatives differ in all spectral properties across all places of articulation. Also, the co-articulatory effects of fricatives on following vowel were different depending on the dialect. Duration, spectral moments, and the starting frequencies of F1, F2, F3, and F4 contributed the most to the classification of dialect. These findings provide a solid evidence base for the manifestation of dialectal information in the acoustic structure of fricatives.

Full Text Available Over the last 50 years, sociolinguistic research in settings in which a regional, social, or ethnic non-standard linguistic variety is used alongside the standard variety of the same language has steadily increased. The educational implications of the concomitant use of such varieties have also received a great deal of research attention. This study deals with regional linguistic variation and its implications for education by focusing on the Greek Cypriot educational context. This context is ideal for investigating the linguistic profiles of speakers of proximal varieties as the majority of Greek Cypriots are primarily educated in just one of their varieties: the standard educational variety. The aim of our study was to understand Greek Cypriot primary school pupils’ sociolinguistic awareness via examination of their written production in their home variety [Cypriot Greek (CG dialect]. Our assumption was that, because written production is less spontaneous than speech, it better reflects pupils’ conscious awareness. Pupils were advised to produce texts that reflected their everyday language with family and friends (beyond school boundaries. As expected, students’ texts included an abundance of mesolectal features and the following were the ten most frequent: (1 palato-alveolar consonants, (2 future particle [ená] and conditional [ítan na] + subjunctive, (3 consonant devoicing, (4 CG-specific verb stems, (5 final [n] retention, (6 [én/ éni] instead of [íne], (7 CG-specific verb endings, (8 [én/é] instead of [ðen], (9 elision of intervocalic fricative [ɣ], and (10 CG-specific adverbs. Importantly, in addition to the expected mesolectal features that reflect contemporary CG, students included a significant and unexpected number of basilectal features and instances of hyperdialectism (that are not representative of today’s linguistic reality which rendered their texts register-inappropriate. This led us to conclude that Greek
Complex analysis and CR geometry
Zampieri, Giuseppe
2008-01-01
Cauchy-Riemann (CR) geometry is the study of manifolds equipped with a system of CR-type equations. Compared to the early days when the purpose of CR geometry was to supply tools for the analysis of the existence and regularity of solutions to the \\bar\\partial-Neumann problem, it has rapidly acquired a life of its own and has became an important topic in differential geometry and the study of non-linear partial differential equations. A full understanding of modern CR geometry requires knowledge of various topics such as real/complex differential and symplectic geometry, foliation theory, the geometric theory of PDE's, and microlocal analysis. Nowadays, the subject of CR geometry is very rich in results, and the amount of material required to reach competence is daunting to graduate students who wish to learn it. However, the present book does not aim at introducing all the topics of current interest in CR geometry. Instead, an attempt is made to be friendly to the novice by moving, in a fairly relaxed way, f...
The geometry description markup language
International Nuclear Information System (INIS)
Chytracek, R.
2001-01-01
Currently, a lot of effort is being put on designing complex detectors. A number of simulation and reconstruction frameworks and applications have been developed with the aim to make this job easier. A very important role in this activity is played by the geometry description of the detector apparatus layout and its working environment. However, no real common approach to represent geometry data is available and such data can be found in various forms starting from custom semi-structured text files, source code (C/C++/FORTRAN), to XML and database solutions. The XML (Extensible Markup Language) has proven to provide an interesting approach for describing detector geometries, with several different but incompatible XML-based solutions existing. Therefore, interoperability and geometry data exchange among different frameworks is not possible at present. The author introduces a markup language for geometry descriptions. Its aim is to define a common approach for sharing and exchanging of geometry description data. Its requirements and design have been driven by experience and user feedback from existing projects which have their geometry description in XML
PREFACE: The 7th International Seminar on Geometry, Continua and Microstructures
Burton, David A.
2007-04-01
It gives me great pleasure to present the proceedings of the 7th International Seminar on Geometry, Continua and Microstructures (GCM 7). The conference took place on 25-27 September 2006 at Lancaster University and the local organisers were Robin Tucker, Tim Walton, myself and Jonathan Gratus of the Lancaster University Mathematical Physics Group. Modern field theories of mechanically and electrically responsive continua have a wealth of interesting applications in physics. Such theories provide effective macroscopic models of complex systems, such as living tissue and material with dynamical defects, that capture macroscopic consequences of microscopic phenomena. GCM is an interdisciplinary conference series, initiated by the Eringen medallist Gérard A Maugin, that brings together physicists and applied mathematicians who have interests in continuum mechanics and differential geometry and who aim to develop new and powerful methods for analysing the behaviour of complex mechanical systems. The earlier conferences in the series were held in Paris, Madrid, Mannheim, Turin, Sinaia and Belgrade. This volume addresses a variety of topics including the physics of saturated porous media, the relationship between growth in living tissue and molecular transport, the mechanics of polymer bonds, the macroscopic properties of damaged elastomers, the mechanics of carbon nanotubes, the geometry of balance systems in Continuum Thermodynamics and wave propagation in the material manifold. I would like to warmly thank the rest of the organising committee and the conference participants for making GCM 7 an enjoyable and rewarding occasion.

This introductory text is designed to help undergraduate students develop a solid foundation in geometry. Early chapters progress slowly, cultivating the necessary understanding and self-confidence for the more rapid development that follows. The extensive treatment can be easily adapted to accommodate shorter courses. Starting with the language of mathematics as expressed in the algebra of logic and sets, the text covers geometric sets of points, separation and angles, triangles, parallel lines, similarity, polygons and area, circles, space geometry, and coordinate geometry. Each chapter incl
Differential geometry curves, surfaces, manifolds
Kohnel, Wolfgang
2002-01-01
This carefully written book is an introduction to the beautiful ideas and results of differential geometry. The first half covers the geometry of curves and surfaces, which provide much of the motivation and intuition for the general theory. Special topics that are explored include Frenet frames, ruled surfaces, minimal surfaces and the Gauss-Bonnet theorem. The second part is an introduction to the geometry of general manifolds, with particular emphasis on connections and curvature. The final two chapters are insightful examinations of the special cases of spaces of constant curvature and Einstein manifolds. The text is illustrated with many figures and examples. The prerequisites are undergraduate analysis and linear algebra.
A Pilot Study of a Cultural-Historical Approach to Teaching Geometry
Rowlands, Stuart
2010-01-01
There appears to be a widespread assumption that deductive geometry is inappropriate for most learners and that they are incapable of engaging with the abstract and rule-governed intellectual processes that became the world’s first fully developed and comprehensive formalised system of thought. This article discusses a curriculum initiative that aims to ‘bring to life’ the major transformative (primary) events in the history of Greek geometry, aims to encourage a meta-discourse that can develop a reflective consciousness and aims to provide an opportunity for the induction into the formalities of proof and to engage with the abstract. The results of a pilot study to see whether 14-15 year old ‘mixed ability’ and 15-16 year old ‘gifted and talented’ students can be meaningfully engaged with two such transformative events are discussed.
Advances in discrete differential geometry
2016-01-01
This is one of the first books on a newly emerging field of discrete differential geometry and an excellent way to access this exciting area. It surveys the fascinating connections between discrete models in differential geometry and complex analysis, integrable systems and applications in computer graphics. The authors take a closer look at discrete models in differential geometry and dynamical systems. Their curves are polygonal, surfaces are made from triangles and quadrilaterals, and time is discrete. Nevertheless, the difference between the corresponding smooth curves, surfaces and classical dynamical systems with continuous time can hardly be seen. This is the paradigm of structure-preserving discretizations. Current advances in this field are stimulated to a large extent by its relevance for computer graphics and mathematical physics. This book is written by specialists working together on a common research project. It is about differential geometry and dynamical systems, smooth and discrete theories, ...

Few data exist concerning the natural history of degenerative osteoarthritis (OA) of the spine and its associated gene investigation. Degenerative spinal OA demonstrates an international prevalence of 15% in the general population. The aim of this Greek case-control study is to examine gene polymorphisms that have been previously shown or hypothesized to be correlated to degenerative OA. Gene polymorphisms, especially for OA, have never been previously studied in the Greek population. The study was conducted from May 2009 to December 2012. Eligible subjects who agreed to take part in the study were Greek adults from all of Greece, referred for consultation to the Palliative Care and Pain Relief Unit of Aretaieion University Hospital, in Athens, Greece. A total of 601 matched pairs (cases and controls) participated in the study, 258 patients (188 women and 70 men) with clinically and radiologically confirmed degenerative OA and 243 control subjects (138 women and 105 men). All patients presented with chronic pain at the spine (cervical, thoracic or lumbar) caused by sympomatic osteophytes or disc narrowing, whereas clinical diagnosis of OA was based on the presence of both joint symptoms and evidence of structural changes seen on plain conventional X-rays. We investigated genetic variation across candidate OA gene GDF5, CDMP1, CDMP2, Asporin, SMAD3, and chromosomal region 7q22, in a sample of 258 patients with clinically and radiologically confirmed degenerative OA, and 243 control subjects from the Greek population. All subjects (patients and controls) were subsequently matched for the epidemiologic, demographic, and clinical risk factors, to prevent selection biases. A tagging single nucleotide polymorphism (SNP) approach was pursued to cover variation across all targeted loci. Single marker tests as well as haplotypic tests of association were performed. There is no conflict of interest, and also, there are no study funding sources. We found significant

Acoustic characteristics of modern Greek Orthodox Church music.
Delviniotis, Dimitrios S
2013-09-01
Some acoustic characteristics of the two types of vocal music of the Greek Orthodox Church Music, the Byzantine chant (BC) and ecclesiastical speech (ES), are studied in relation to the common Greek speech and the Western opera. Vocal samples were obtained, and their acoustic parameters of sound pressure level (SPL), fundamental frequency (F0), and the long-time average spectrum (LTAS) characteristics were analyzed. Twenty chanters, including two chanters-singers of opera, sang (BC) and read (ES) the same hymn of Byzantine music (BM), the two opera singers sang the same aria of opera, and common speech samples were obtained, and all audio were analyzed. The distribution of SPL values showed that the BC and ES have higher SPL by 9 and 12 dB, respectively, than common speech. The average F0 in ES tends to be lower than the common speech, and the smallest standard deviation (SD) of F0 values characterizes its monotonicity. The tone-scale intervals of BC are close enough to the currently accepted theory with SD equal to 0.24 semitones. The rate and extent of vibrato, which is rare in BC, equals 4.1 Hz and 0.6 semitones, respectively. The average LTAS slope is greatest in BC (+4.5 dB) but smaller than in opera (+5.7 dB). In both BC and ES, instead of a singer's formant appearing in an opera voice, a speaker's formant (SPF) was observed around 3300 Hz, with relative levels of +6.3 and +4.6 dB, respectively. The two vocal types of BM, BC, and ES differ both to each other and common Greek speech and opera style regarding SPL, the mean and SD of F0, the LTAS slope, and the relative level of SPF.

Greece has the highest adult smoking prevalence in the European Union, affecting not only those who smoke but also threatening the health of those who are involuntarily exposed to passive smoke, especially young Greek children. The aim of this study was to quantify passive smoking biomarkers (serum nicotine and cotinine levels) among preschool children in Crete in relation to parental smoking habits. All children enrolled in kindergarten in western Crete (1,757 preschool children and 2,809 parents) were interviewed during the 2004-2005 Cretan health promotion programme out of which a sample of 81 children was randomly selected according to parental smoking status and blood samples for cotinine and nicotine assay were taken. The geometric means of serum nicotine values in children with both parents current smokers and in those with both parents non-smokers were 0.71 ng/ml (95%CI 0.62, 0.80) and 0.59 ng/ml (95%CI 0.49, 0.69), respectively, (p=0.073). Cotinine geometric mean values were found at 1.69 ng/ml (95%CI 0.93, 3.06) and 0.15 ng/ml (95%CI 0.09, 0.28), respectively, (pparents had also greater cotinine geometric mean values than boys (3.35 versus 0.85 ng/ml, respectively, p=0.018). Our findings prove that Greek preschool children, especially young girls, are exposed to substantial levels of passive smoke which therefore stresses the need for immediate action so as to prevent the predisposition and early addiction of Greek preschool children to tobacco.

According to Greek legislation the medico-legal investigation of deaths occurring in prisons is mandatory. Furthermore, in cases of suicide or of suspected suicide the contribution of medico-legal investigation is of grave importance. The current paper addresses the medico-legal investigation of suicide cases in Greek correctional facilities and aims to describe the current situation. Our study consists of the meticulous research in the data records of major Greek correctional facilities, for the time period 1999-2010. Official permission was obtained by the Hellenic Ministry of Justice, which provided us the access to the records. Data was also collected from the Piraeus Forensic Service, from the Department of Pathological Anatomy of the University of Athens and finally from our own records. Measures were taken to respect the anonymity of the cases. Data was collected for the social, penal, medical history as well as for the medico-legal investigation. It appears that 85.7% of suicide cases were transferred to the Prisoner's Hospital (p < 0.0001), the forensic pathologist who conducted the PME did not perform scene investigation in none of the 70 suicide cases. In a total of 70 cases, histopathological examination, was requested only in 30 cases (42.9%). Hanging was the preferred method for those who committed suicide, followed by the poisoning due to psychoactive substances. Understanding the mistakes made during the forensic investigation of suicide cases inside correctional facilities is necessary, in order to prevent them from occurring again in the future, by implementing appropriate new policies and guidelines.

HPV is associated with malignancy in men, yet there is a lack of data on HPV knowledge, vaccine acceptability, and factors affecting vaccine acceptability in Greek men. This study aims to identify determinants of knowledge and willingness to vaccinate against HPV among high-risk Greek men. Men (n = 298) between the ages of 18 and 55 were enrolled from the STI and HIV clinics at "Andreas Syggros" Hospital in Athens, Greece from July-October 2015. Participants completed a survey on demographics, economic factors, sexual history, HPV knowledge, and vaccine acceptability. The majority of participants were younger than 40 (76.6%) and unmarried (84.6%). Our sample was 31.2% MSM (men who have sex with men), and 20.1% were HIV-positive. Most participants (>90%) were aware that HPV is highly prevalent in both men and women; however, fewer identified that HPV causes cancers in both sexes (68%) and that vaccination protects men and women (67%). Amongst participants, 76.7% were willing to vaccinate themselves against HPV, 71.4% an adolescent son, and 69.3% an adolescent daughter. HIV-positive men were more likely to be willing to vaccinate themselves (OR 2.83, p = .015), a son (OR 3.3, p = .015) or a daughter (3.01, p = .020). Higher income levels were associated with increased willingness to vaccinate oneself (OR 1.32, p = .027), a son (1.33, p = .032) or daughter (1.34, p = .027). Although there is a HPV knowledge gap, HPV vaccine acceptability is high despite lack of vaccine promotion to Greek men. Future studies should include lower-risk men to adequately inform public health efforts.
Greek Monk Theodore as the first Primate of Canterbury

Full Text Available The theological climate of the young Church of Anglo-Saxon Christians was determined by Irish and Welsh monks maintaining the tradition of the Egyptian desert. The Angles and Saxons had a particular vision of the natural world, of the eternal world, a particular comprehension of sin and repentance. Rome in its missionary work used them to attach the British Christians the see of St Peter. Britain had no original link with the culture and tradition of the classical Church. It has been particularly established and enforced in VII and VIII, when England received a great dose of classical learning and theology due to the activity of archbishop of Canterbury Theodore and monk Hadrian. The formerly Greek monk Theodore – well learned in the Holy Scripture as well as Greek and Latin classics – was named the archbishop of Canterbury by pope Vitalian under the condition that he should notintroduce any typically Greek customs. Theodore named Hadrian the abbot of the Canterbury monastery of St Peter. There and in York young English could pursue classical studies of the Holy Scriptures, poetry, philosophy, mathematics, astronomy, etc. It resulted in significant literary development in Britain, of which venerable Bede is an example.Theodore introduced in Canterbury proto-byzantine canonical law, during two famous synods established doctrinal and ecclesiastical foundations of English Christianity based on ancient orthodox tradition of Eastern part of the Mediterranean region. At the Synod of Hatfield,with the other bishops, Theodore confirmed the Nicean Creed, fiveformer ecumenical councils and the generally accepted Church Fathers. They worked also on practical church unity, that is established: common date of Easter with other parts of Christian world, non-intervention ofbishops in other dioceses, canonical laws regulating the attitude of bishops towards monastic communities and the decrees against monophysismonks coming from Persia.
Investigating the real situation of Greek solar water heating market

Kaldellis, J.K.; Kavadias, K.A.; Spyropoulos, G.
2005-01-01
Solar thermal applications have been acknowledged among the leading alternative solutions endeavouring to face the uncontrollable oil price variations, the gradual depletion of fossil fuel reserves and the chain environmental consequences caused by its excessive usage. Almost 30 years after the initial emergence of the commercial domestic solar water heating system (DSWHS) in the European market, the corresponding technology is qualified as quite mature. On top of this, the European Commission expects that 100,000,000 m 2 of solar collectors are to be installed in Europe by the year 2010 to facilitate durable and environment-friendly heat. In this context, the Greek DSWHSs market is highly developed worldwide, having a great experience in this major energy market segment. The present study is devoted to an extensive evaluation of the local DSWHSs market, including a discerning analysis of its time variation, taking seriously into account the corresponding annual replacement rate. Accordingly, the crucial techno-economic reasons, limiting the DSWHSs penetration in the local heat production market, are summarized and elaborated. Subsequently, the national policy measures - aiming to support the DSWHSs in the course of time - are cited, in comparison with those applied in other European countries. Next, the financial attractiveness of a DSWHS for Greek citizens is examined in the local socio-economic environment. The present work is integrated by reciting the prospects and mustering certain proposals that, if applied, could stimulate the local market. As a general comment, the outlook for penetration of new DSWHSs in the local market is rather grim, as the current techno-economic situation of solar heat cannot compete with oil and natural gas heat production, unless the remarkable social and environmental benefits of solar energy are seriously considered. Hence, the Greek State lacks stimulus to further DSWHSs installations, being strongly in support of the imported
The carbon footprint of Greek households (1995–2012)

2017-01-01
The goal of this paper is twofold: i) to investigate the carbon footprint of Greek households throughout the period 1995–2012, in order to identify the main socio-economic factors that affect GHG emissions, and ii) to evaluate the effectiveness of the implemented policies to tackle climate change. In this, a consumption-based emissions inventory approach is applied. The analysis is based on an environmentally-extended input-output model including direct CO_2 emissions from households, indirect CO_2 emissions from electricity consumption and indirect CO_2 emissions from energy used in the production of goods and services purchased by households, domestic or imported. Statistical analysis and appropriate regression models were developed in order to identify the main factors influencing the carbon footprint of Greek households. The results indicate that the observed trends during the period 1995–2008 can be attributed to the effect of high economic growth. This trend is partially counterbalanced by favorable weather conditions and the implementation of greenhouse mitigation policies and measures mainly in the supply side. Since 2008 the shrinking household income is the dominant driver. In addition, the effectiveness of energy conservation policies and measures in place is rather low, while the effect of imports is limited. - Highlights: • The factors influencing the carbon footprint of Greek households have been analyzed. • The analysis is based on consumption-based GHG inventories. • High economic growth resulted in carbon footprint increases during 1995–2008. • Carbon footprint reduction after 2008 is attributed to shrinking of household income. • Mitigation measures in power and manufacturing sectors reduced carbon footprint.
HISTORICAL CONCEPTIONS OF A HEALTHY CITY: THE GREEK PARADIGM
Directory of Open Access Journals (Sweden)
Sophia Chatzicocoli
2009-03-01
Full Text Available Today much attention is being given to the concept of a “healthy city”. However, the need for incoming paradigms is needed since this concept is still developing both as a term and as a real experience. The study of the historical experiences and examples can enrich the understanding of a healthy city’s historical background and can help in learning from the past. Especially the Greek paradigm appears of a particular importance as the idea of the creation of healthy cities seems to be central in the Hellenic (Greek culture, the first anthropocentric culture developed in Europe, which is perceived to form the base of the so called Western Civilization. The conceptions of a healthy city were supported by the Hellenic Mythology, Philosophy, Art and Science. The principles of the planning and design of healthy cities were expressed through various applications concerning the Greek cities and, especially, through the creation of specific settlements devoted to the restoration of health, such as Asklepieia. Asklepieia were centres of worship of the hero, divine physician and healing god, Asklepios and became the first health care centres in Europe. Asklepieia offered their healing environment and services for many centuries in the then Hellenic territory, from the pre-historic era and the War of Troy though out the Classical, Hellenistic and Roman times to the early-Byzantine times until the total prevalence of Christianity. In Asklepieia the restoration of health was understood as a result of positive interaction of physical, psychological, mental, spiritual, social, environmental, etc, factors.
Spectral dimension of quantum geometries
International Nuclear Information System (INIS)
Calcagni, Gianluca; Oriti, Daniele; Thürigen, Johannes
2014-01-01
The spectral dimension is an indicator of geometry and topology of spacetime and a tool to compare the description of quantum geometry in various approaches to quantum gravity. This is possible because it can be defined not only on smooth geometries but also on discrete (e.g., simplicial) ones. In this paper, we consider the spectral dimension of quantum states of spatial geometry defined on combinatorial complexes endowed with additional algebraic data: the kinematical quantum states of loop quantum gravity (LQG). Preliminarily, the effects of topology and discreteness of classical discrete geometries are studied in a systematic manner. We look for states reproducing the spectral dimension of a classical space in the appropriate regime. We also test the hypothesis that in LQG, as in other approaches, there is a scale dependence of the spectral dimension, which runs from the topological dimension at large scales to a smaller one at short distances. While our results do not give any strong support to this hypothesis, we can however pinpoint when the topological dimension is reproduced by LQG quantum states. Overall, by exploring the interplay of combinatorial, topological and geometrical effects, and by considering various kinds of quantum states such as coherent states and their superpositions, we find that the spectral dimension of discrete quantum geometries is more sensitive to the underlying combinatorial structures than to the details of the additional data associated with them.

2009-01-01
Turko-Greek relations have been strained by a number of conflicting issues such as Cyprus, Continental Shelf, Territorial Waters, the Öcalan affair, and the S-300 Missiles crisis on Cyprus. Until the December 1999 Helsinki Summit, Greece was one of the strong opponents of Turkey's membership in the European Union (EU). However, at the Helsinki Summit of 1999, Greece dropped her negative position permitting Turkey to be declared by the EU as a candidate country. This shift in foreign policy ha...
Analysis of Greek small coinage from the classic period
Šmit, Ž.; Šemrov, A.
2018-02-01
A series of 25 Greek coins from the 6th to 4th centuries BC was studied by PIXE for their trace element composition, with an aim to discover the origin of their silver ore. The procedure revealed a counterfeited coin, and then concentrated on distinguishing the coins minted from the ore of Laurion on the Attica peninsula and the coins minted from other sources. Linear discriminant analysis based on the impurities and alloying elements of copper, gold, lead and bismuth revealed that discrimination is indeed possible according to a single canonical variable.
Assessment of the lower ESR dating range in Greek speleothems
International Nuclear Information System (INIS)
Bassiakos, Y.
2001-01-01
Pilot ESR dating studies on geologically young calcitic sinters were carried out, aiming at assessment of the lower ESR dating range in characteristic Greek speleoenvironments. Five stalactites were dated, coming from an ancient mining gallery, idle for the last 2,500 years, found on Siphnos island (Aegean). The calculated ages range between 1,7-2,0 ka. Medium to low measured external dose rates (aprox. 900 μGy/a) and very low measured radioelement concentration in samples are very usual in the Mediterranean environments. The study concludes that ESR dating of speleothems younger than two millenia is practically unattainable. Some geoarchaeological implications of the obtained ages are discussed. (author)
More on the Greek fable and its origins
Directory of Open Access Journals (Sweden)
Francisco Rodríguez Adrados
2014-12-01
Full Text Available Some years have passed since the publication of Adrados’ book History of the Graeco-Latin Fable, it is convenient to add some novelties. First of all, a mention must be added to books by Jedrkiewicz, van Dijk and also by Adrados. Then, a reference is needed also to Sumerian, Acadian and Egyptian fables which have left some motives in the greek Fable. In particular, are important some myths related to the creation of men and animals: their original nature must be preserved, if not bad consequences originate. That is the old wisdom of proverbs and fables, nature does nor change. Some omnipresent examples are presented.

Greek marbles: determination of provenance by isotopic analysis.
Craig, H; Craig, V
1972-04-28
A study has been made of carbon-13 and oxygen-18 variations in Greek marbles from the ancient quarry localities of Naxos, Paros, Mount Hymettus, and Mount Pentelikon. Parian, Hymettian, and Pentelic marbles can be clearly distinguished by the isotopic relationships; Naxian marbles fall into two groups characterized by different oxygen-18/oxygen-16 ratios. Ten archeological samples were also analyzed; the isotopic data indicate that the "Theseion" is made of Pentelic marble and a block in the Treasury of Siphnos at Delphi is probably Parian marble.

Full Text Available Review of: Vinzenz Brinkmann, Oliver Primavesi, Max Hollein, (eds, Circumlitio. The Polychromy of Antique and Medieval Sculpture. Liebighaus Skulpturensammlung, Frankfurt am Main, 2010. New scientific methods now being applied to the analysis of traces of pigments and gilding on ancient Greek and Roman marble statuary, and other marble artefacts, have the potential to revolutionise our understanding of the relationship between form and colour in antiquity. At present the enquiry is still in its infancy, but the papers delivered at a conference held in Frankfurt in 2008, reviewed here, provide a general introduction to the subject and to a wide range of work in progress.
Uxoricide in pregnancy: ancient Greek domestic violence in evolutionary perspective.
Deacy, Susan; McHardy, Fiona
2013-10-24
Previous studies of ancient Greek examples of uxoricide in pregnancy have concluded that the theme is used to suggest tyrannical abuse of power and that the violence is a product of the patriarchal nature of ancient society. This article uses evolutionary analyses of violence during pregnancy to argue that the themes of sexual jealousy and uncertainty over paternity are as crucial as the theme of power to an understanding of these examples and that the examples can be seen as typical instances of spousal abuse as it occurs in all types of society.
Mental health and sexual activity according to ancient Greek physicians.
Laios, K; Tsoucalas, G; Kontaxaki, Μ-Ι; Karamanou, Μ; Sgantzos, Μ; Androutsos, G
2015-01-01
The ancient Greek physicians have not failed in their studies to indicate the beneficial role of sexual activity in human health. They acknowledged that sex helps to maintain mental balance. Very interesting is their observation that sex may help mental patients to recover. Nevertheless they stressed emphatically that sex is beneficial only when there is a measure in it, so they believed that sexual abstinence or excessive sexual activity affect negatively the mental and physical health of man. Ancient Greek physicians reached this conclusion by empirical observation. They tried to justify the mental imbalance, as the potential physical problems, which probably will be listed today in the psychosomatic manifestations, of people with long-term sexual abstinence or hyperactivity, based on the theory of humors which was the main methodological tool of ancient Greek medicine. Their fundamental idea was that the four humors of the body (blood, phlegm, yellow and black bile) should be in balance. Therefore they believed that the loss and the exchange of bodily fluids during sex help body's humors to maintain their equilibrium which in turn will form the basis for the physical and mental health. Although in ancient medical texts the irrationality presented by people in the aforementioned conditions was not attributed in any of the major mental illnesses recognized in antiquity, as mania, melancholy and phrenitis, our belief is that their behavior is more suited to the characteristics of melancholy, while according to modern medicine it should be classified in the depressive disorders. We have come to this conclusion, because common characteristics of people who either did not have sexual life or was overactive, was sadness, lack of interest and hope, as well as paranoid thinking that can reach up to suicide. Regarding the psychosomatic problems, which could occur in these people, they were determined by the ancient Greek physicians in the following; continuous headaches
The Greek Financial Crisis: Discourses of Difference or Solidarity?
Directory of Open Access Journals (Sweden)
Hans Bickes
2014-05-01
Full Text Available The so-called Greek Financial Crisis, which has been the object of close attention in the German media since the end of 2009, has caused a public debate on who should be held responsible for the decline of crisis-hit Greece, the common currency and the Eurozone. The media’s enduring and controversial public discussion has lately been referred to as the Greek bashing. When the crisis had spread much further in 2012 and also other countries suffered from high debt, economic stagnation and unemployment, the news coverage became more moderate. This project report highlights the role of medial discourses of difference and solidarity during the crisis. Therefore, we rely on an exemplary data-set that does not only take the development of the German media’s tenor on the Greek Crisis into consideration, but also adds an international perspective in order to compare the medial treatment of different countries involved. The study methodologically focuses on the analysis of (metaphorical language and grammatical structures in the news coverage of the German daily newspaper BILD, the German magazine SPIEGEL as well as the international news magazines Economist (Great Britain and TIME (USA. Therefore, the interdisciplinary approach of Critical Discourse Analysis (CDA was used in order to produce insights into public discourses in sociopolitical contexts. Deutsche Medien haben der sogenannten Griechischen Finanzkrise erhebliche Aufmerksamkeit gewidmet.

Nachdem sich die Krise 2012 auf andere Mitgliedsstaaten ausdehnte und dort zu hoher Staatsverschuldung, ökonomischer Stagnation und Arbeitslosigkeit führte, nahmen Mediendiskurse (auch zu
Policy Advice from Seneca and Machiavelli on the Greek Crisis

Tom Lynch
2012-12-01
Full Text Available Since 2008 economic crisis has dominated global economic policy discussions, no more so than in Greece. In Greece, the imposition of austerity policies has caused immense social and political upheaval. I suggest that policy thinking about the current Greek debt crisis requires a broader engagement with global civic virtue. Specifically, I present a case for revisiting the political thought of Seneca and Machiavelli. Both discuss the virtue of mercy and its role in good governance policy. I argue that policy solutions for the economic crisis facing Greece and Europe need to be informed by their thinking.

Global financial crisis and surgical practice: the Greek paradigm.
Karidis, Nikolaos P; Dimitroulis, Dimitrios; Kouraklis, Gregory
2011-11-01
Apart from the significant implications of recent financial crisis in overall health indices and mortality rates, the direct effect of health resources redistribution in everyday clinical practice is barely recognized. In the case of Greece, health sector reform and health spending cuts have already had a major impact on costly interventions, particularly in surgical practice. An increase in utilization of public health resources, lack of basic and advanced surgical supplies, salary deductions, and emerging issues in patient management have contributed to serious dysfunction of a public health system unable to sustain current needs. In this context, significant implications arise for the surgeons and patients as proper perioperative management is directly affected by reduced public health funding. The surgical community has expressed concerns about the quality of surgical care and the future of surgical progress in the era of the European Union. Greek surgeons are expected to support reform while maintaining a high level of surgical care to the public. The challenge of cost control in surgical practice provides, nevertheless, an excellent opportunity to reconsider health economics while innovation through a more traditional approach to the surgical patient should not be precluded. A Greek case study on the extent of the current situation is presented with reference to health policy reform, serving as an alarming paradigm for the global community under the pressure of a profound financial recession.
Greek students' knowledge and sources of information regarding sex education.
Matziou, V; Perdikaris, P; Petsios, K; Gymnopoulou, E; Galanis, P; Brokalaki, H
2009-09-01
Human sexuality is a complex part of life and is considered a multidimensional phenomenon. Therefore there is an increased need for adequate and comprehensive sex education, especially for teenagers and young adults. The main aim of the study was to evaluate the level of students' sexual knowledge, as well as to identify their sources of information regarding sexual life and reproduction. A cross-sectional study using a designed self-report questionnaire was performed. The study population consisted of 936 students who were attending 10 high schools and four medical schools in Attica. Data were collected after obtaining permission from the Pedagogic Institute of the Greek Ministry of Education. The main sources of students' sexual information about reproduction were friends (29.1%) and parents (24.0%), whereas school was reported by 14.3% of them. The preferred sources of information, according to students' perceptions, were sex education specialists (65.6%), followed by school (39.1%), parents (32.2%) and friends (27.7%). The importance of school, peer and parent support upon adolescents' sexual life was revealed by the results of the study. Students' knowledge level on sex topics is not satisfactory and therefore there is a need for sex education specialists and special courses regarding sex education in Greek schools.

Recurrent pregnancy loss (RPL) is a multifactorial disorder. The aim of this study was the detection of various genetic polymorphisms and their correlation to RPL, in Greek women. The impact of 12 thrombophilic polymorphisms was evaluated, among 48 Greek women with a history of RPL, vs 27 healthy parous women. Multiplex PCR and in situ hybridization on nitrocellulose films were performed, to investigate 12 genetic polymorphisms previously reported as risk factors for RPL. Heterozygous FV Leiden, homozygous PAI-1 4G/4G, heterozygous MTHFR C677T, homozygous MTHFR A1298C, as much as the combined thrombophilic genotypes MTHFR 677T + ACE Ι/D, MTHFR 677T/1298C + ACE D/D, ACE I/D + b-fibrinogen -455 G/A, FV HR2 + b-fibrinogen -455 G/A showed a correlation as risk factors for RPL, whereas the rest of the investigated polymorphisms and their combinations did not render statistically significant differences between the two groups in study. The results of this study, as well as those of similar studies, concerning the detection of genetic, environmental, and physiological factors underlying RPL, will prove of critical significance in the investigation and treatment of thrombophilic predisposition, in cases of RPL. © 2017 John Wiley & Sons Ltd.

2006-01-01
Serum copper and zinc concentrations of 506 (414 males and 92 females) apparently healthy Greek blood donors aged 18-60 years old were determined by flame atomic absorption spectrometry. The mean copper and zinc concentrations were 115.46 ± 23.56 μg/dl and 77.11 ± 17.67 μg/dl, respectively. The mean value for copper and zinc in females was higher than in males, although the difference for zinc was smaller than the one observed for copper. When the subjects were divided into various age groups there appeared to be some increase in copper concentration as a function of age, whereas zinc concentration did not change. There were no significant variations in serum copper and zinc concentrations due to place of residence, occupation and socioeconomic status. This study is the first one evaluating the serum status of copper and zinc in healthy Greeks and it has shown that they are at the highest concentration range for copper and the lowest for zinc compared to literature data on copper and zinc levels for various countries

Electricity curtailment behaviors in Greek households: Different behaviors, different predictors
International Nuclear Information System (INIS)
Botetzagias, Iosif; Malesios, Chrisovaladis; Poulou, Dimitra
2014-01-01
Highlights: • We study the self-reported energy (electricity) curtailment behaviors of Greek households (N=285). • We find that the curtailment behaviors are distinct and should be studied/analyzed separately. • ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ are statistically significant predictors of most behaviors. • The demographic/structural and the psychological predictors contribute significantly explain the variance of the behaviors. • The cluster of moral predictors does not contribute statistically significantly to the explained variance. - Abstract: This paper argues that electricity ‘curtailment’ behaviors (i.e. frequent and/or low cost or free energy saving behaviors) in households are distinct from one another and they thus should be analyzed and promoted. We test this claim with data from telephone interviews with Greek households in the capital city of Athens (N=285), analyzing the impact of a number of demographical/structural, psychological (based on the Theory of Planned Behavior) and moral (based on norms’ activation) predictors though hierarchical binary logistic regression modeling. We find that that each electricity curtailment behavior depends on a different mix of predictors with ‘Age’, ‘Gender’ and ‘Perceived Behavioral Control’ being statistically significant for most behaviors. Overall, the psychological and the demographical/structural clusters of variables substantially contribute to the explained variance of electricity curtailment behaviors. The moral cluster's contribution is not statistically significant since moral concerns are largely interwoven in the psychological constructs
The accounting and tax legislation of the Greek football clubs
Directory of Open Access Journals (Sweden)
PANAGIOTIS E. DIMITROPOULOS
2006-01-01
Full Text Available The year 1979 was a cornerstone for the football in Greece, since it practically meant the transformation of the sport’s organization from amateurism to professionalism, establishing new rules and conditions to the management of football clubs. The increased popularity of this sport and the evolutions that took place in Europe and worldwide, forced the Greek government to establish a legislative framework for the successful management of football clubs. These interventions lead to changes in many aspects of football management such as organizational and financial. The new legal environment of football management, required the organization of this sport into a more stable and professional base, following the financial standards of other corporations operating within the Greek state. By these means the government wanted to create a fair economic framework under which the football clubs would operate with common organizational, financial and tax administration rules. The aim of this paper is to present the characteristics of the new «capital form» establishment of the football clubs (Societe Anonyme, the main financial frame under which the new establishment has to operate and the tax obligations that originate from the aforementioned legal form.
American and Greek Children's Visual Images of Scientists
Christidou, Vasilia; Bonoti, Fotini; Kontopoulou, Argiro
2016-08-01
This study explores American and Greek primary pupils' visual images of scientists by means of two nonverbal data collection tasks to identify possible convergences and divergences. Specifically, it aims to investigate whether their images of scientists vary according to the data collection instrument used and to gender. To this end, 91 third-grade American ( N = 46) and Greek ( N = 45) pupils were examined. Data collection was conducted through a drawing task based on Chambers (1983) `Draw-A-Scientist-Test' (DAST) and a picture selection task during which the children selected between 14 pairs of illustrations those that were most probable to represent scientists. Analysis focused on stereotype indicators related with scientists' appearance and work setting. Results showed that the two groups' performance varied significantly across the tasks used to explore their stereotypic perceptions, although the overall stereotypy was not differentiated according to participants' ethnic group. Moreover, boys were found to use more stereotypic indicators than girls, while the picture selection task elicited more stereotypic responses than the drawing task. In general, data collected by the two instruments revealed convergences and divergences concerning the stereotypic indicators preferred. Similarities and differences between national groups point to the influence of a globalized popular culture on the one hand and of the different sociocultural contexts underlying science curricula and their implementation on the other. Implications for science education are discussed.
Suicidal behaviour in the ancient Greek and Roman world.
Lykouras, L; Poulakou-Rebelakou, E; Tsiamis, C; Ploumpidis, D
2013-12-01
We attempt to present and analyze suicidal behaviour in the ancient Greek and Roman world. Drawing information from ancient Greek and Latin sources (History, Philosophy, Medicine, Literature, Visual Arts) we aim to point out psychological and social aspects of suicidal behaviour in antiquity. The shocking exposition of suicides reveals the zeitgeist of each era and illustrates the prevailing concepts. Social and legal reactions appear ambivalent, as they can oscillate from acceptance and interpretation of the act to punishment. In the history of these attitudes, we can observe continuities and breaches, reserving a special place in cases of mental disease. The delayed emergence of a generally accepted term for the voluntary exit from life (the term suicidium established during the 17th century), is connected to reactions triggered by the act of suicide than to the frequency and the extent of the phenomenon. The social environment of the person, who voluntary ends his life usually dictates the behaviour and historical evidence confirms the phenomenon. Copyright © 2013 Elsevier B.V. All rights reserved.
Public stigma towards mental illness in the Greek culture.
Tzouvara, V; Papadopoulos, C
2014-12-01
Mental illness stigma negatively affects the lives of individuals with mental health disorders. Studies have indicated that the type and degree of stigma significantly varies across cultures. This study aimed to add to this body of knowledge by examining the prevalence and the type of mental illness stigma among individuals who identified themselves as Greek. It also examined the influence of a range of potential within-culture stigma moderating factors, including levels of previous experience with mental illness and mental illness knowledge. A cross-sectional quantitative design was employed, and 111 participants living in England and Greece were sampled through the snowball sampling technique. Stigma prevalence was measured using the 'Community Attitudes to Mental Illness' questionnaire. The findings revealed that participants showed a high degree of sympathy for people with mental illness but also considered them to be inferior and of a lower social class, and needing strict societal control. Higher stigma was significantly associated with being educated in England (instead of Greece), higher religiosity, lower knowledge levels and lower levels personal experience of mental illness. Targeted antistigma campaigns specifically tailored for the Greek culture are required in order to help reduce stigmatizing attitudes. © 2014 John Wiley & Sons Ltd.
The impact of a carbon tax on Greek electricity production

The impact of proposed carbon taxes on the electric power industry, using the Greek power system as a case study, is investigated in this paper. It uses the WASP model for electric generation capacity expansion to explore the optimal expansion path under alternative carbon tax scenarios and to estimate their impact on CO{sub 2} and other types of emissions and on electricity production costs. The findings suggest that low carbon taxes would lead to a considerable reduction of the use of conventional lignite fired power plants counterbalanced predominantly by natural gas fired plants. High carbon taxes (100-200 US dollars per ton of carbon) would lead to a drastic reduction of the use of conventional lignite fired power plants which would be mainly replaced by coal or lignite fired technologies with CO{sub 2} removal capabilities, which are not available today but might become available within the time horizon of the present study. Hydropower and renewable sources would be the second least-cost alternatives to lignite under both low and high tax scenarios. The study provides evidence that carbon taxes also result in significant increases in the cost of producing electricity, implying adverse economic effects on electricity consumers and the Greek economy in general.

Reforms in the Greek pharmaceutical market during the financial crisis.
Vandoros, Sotiris; Stargardt, Tom
2013-01-01
Following the financial crisis of 2008, Greece has been facing severe fiscal problems associated with high public debt and deficit. Given their significant contribution to public sector expenditure, part of the effort to reduce public expenditure has involved a focus on pharmaceutical markets. Our aim is to provide an overview of recent policy changes in the Greek pharmaceutical market as a response to the crisis. We also discuss other potential measures that can be implemented. The recommendations are relevant to European countries facing debt crises, but also to any other country, as improving efficiency makes funds available to be used on other interventions. In 2010 and 2011, following the debt crisis and the agreement with the IMF, EU and ECB, the Greek government introduced several policy measures aimed at cost-containment. These changes included (a) price cuts, (b) the re-introduction of a positive list, (c) changes in the profit margins of pharmacies and wholesalers, and (d) tenders for hospital drugs. As a result, public drug expenditure decreased from €5.09 billion in 2009 to €4.25 billion in 2010 and €4.10 billion in 2011. As the need to cut expenditure becomes more urgent, seeking efficiency is possibly the only option for countries that do not wish to compromise quality of healthcare and public health. However, efficiency and cost containment are not only about introducing new policies, but also about the enforcement of existing laws and fighting corruption. Copyright © 2012 Elsevier Ireland Ltd.

The impact of a carbon tax on Greek electricity production
International Nuclear Information System (INIS)
Vassos, S.; Vlachou, A.
1997-01-01
The impact of proposed carbon taxes on the electric power industry, using the Greek power system as a case study, is investigated in this paper. It uses the WASP model for electric generation capacity expansion to explore the optimal expansion path under alternative carbon tax scenarios and to estimate their impact on CO 2 and other types of emissions and on electricity production costs. The findings suggest that low carbon taxes would lead to a considerable reduction of the use of conventional lignite fired power plants counterbalanced predominantly by natural gas fired plants. High carbon taxes (100-200 US dollars per ton of carbon) would lead to a drastic reduction of the use of conventional lignite fired power plants which would be mainly replaced by coal or lignite fired technologies with CO 2 removal capabilities, which are not available today but might become available within the time horizon of the present study. Hydropower and renewable sources would be the second least-cost alternatives to lignite under both low and high tax scenarios. The study provides evidence that carbon taxes also result in significant increases in the cost of producing electricity, implying adverse economic effects on electricity consumers and the Greek economy in general.

Shaping the pain: Ancient Greek lament and its therapeutic aspect?
Directory of Open Access Journals (Sweden)
Šijaković Đurđina
2011-01-01
Full Text Available In this paper, which is the first part of a wider research, I focus on different aspects of ancient Greek lament. One of its most important aspects is the therapeutic aspect: by verbalizing, revealing the pain and by sharing it with others, the pain itself is becoming more bearable both for the woman that laments and for the bereaved family. Related to this therapeutic is the creative aspect of lament: the woman that mourns has to lament in order to make it easier for herself and others; but while lamenting, she is creating something. In spite of this constructive, let us call it creative-therapeutic potential, the lament carries in itself a different, rather dark and gloomy potential, if it calls for vengeance, not reconciling with the fact of someone dear’s death. Deeply rooted in funeral ritual, a lament respects certain ritual rules, and yet it is a spontaneous expression of pain. Examining these mutually dependent aspects of lament, I will turn attention to the position of lament in Greek rites and tragedy, that summit Greek art and literature. Ritual lament within ancient tragedy is, as always when it comes to Greek culture, an inexhaustible topic. Although tragedy belongs to literary tradition, it is a trustworthy source for ancient Greek ritual practice; lament within tragedy is thus a ritual lament, and not only a literary one. Characters of many tragedies will mention the therapeutic aspect of lament, examined in this paper: they consider tears, wails and words directed to the deceased as joyful service, enjoyment, music, song precious and indispensable. This paper has its supplement, shaping the pain in few case studies. Inspired by laments of Montenegrin women, those that I have heard or read, I am re-reading Euripides’ Electra and Electra by Danilo Kiš (in which both Euripides’ drama and Montenegrin folklore is reflected, I am watching the Michalis Kakojannis’ movie Electra. Electra’s pain for loss, the one that through
Variable geometry Darrieus wind machine
Pytlinski, J. T.; Serrano, D.
1983-08-01
A variable geometry Darrieus wind machine is proposed. The lower attachment of the blades to the rotor can move freely up and down the axle allowing the blades of change shape during rotation. Experimental data for a 17 m. diameter Darrieus rotor and a theoretical model for multiple streamtube performance prediction were used to develop a computer simulation program for studying parameters that affect the machine's performance. This new variable geometry concept is described and interrelated with multiple streamtube theory through aerodynamic parameters. The computer simulation study shows that governor behavior of a Darrieus turbine can not be attained by a standard turbine operating within normally occurring rotational velocity limits. A second generation variable geometry Darrieus wind turbine which uses a telescopic blade is proposed as a potential improvement on the studied concept.
Flux compactifications and generalized geometries
International Nuclear Information System (INIS)
Grana, Mariana
2006-01-01
Following the lectures given at CERN Winter School 2006, we present a pedagogical overview of flux compactifications and generalized geometries, concentrating on closed string fluxes in type II theories. We start by reviewing the supersymmetric flux configurations with maximally symmetric four-dimensional spaces. We then discuss the no-go theorems (and their evasion) for compactifications with fluxes. We analyse the resulting four-dimensional effective theories for Calabi-Yau and Calabi-Yau orientifold compactifications, concentrating on the flux-induced superpotentials. We discuss the generic mechanism of moduli stabilization and illustrate with two examples: the conifold in IIB and a T 6 /(Z 3 x Z 3 ) torus in IIA. We finish by studying the effective action and flux vacua for generalized geometries in the context of generalized complex geometry

Euclidean geometry and its subgeometries
Specht, Edward John; Calkins, Keith G; Rhoads, Donald H
2015-01-01
In this monograph, the authors present a modern development of Euclidean geometry from independent axioms, using up-to-date language and providing detailed proofs. The axioms for incidence, betweenness, and plane separation are close to those of Hilbert. This is the only axiomatic treatment of Euclidean geometry that uses axioms not involving metric notions and that explores congruence and isometries by means of reflection mappings. The authors present thirteen axioms in sequence, proving as many theorems as possible at each stage and, in the process, building up subgeometries, most notably the Pasch and neutral geometries. Standard topics such as the congruence theorems for triangles, embedding the real numbers in a line, and coordinatization of the plane are included, as well as theorems of Pythagoras, Desargues, Pappas, Menelaus, and Ceva. The final chapter covers consistency and independence of axioms, as well as independence of definition properties. There are over 300 exercises; solutions to many of the...

Electrodynamics and Spacetime Geometry: Foundations
Cabral, Francisco; Lobo, Francisco S. N.
2017-02-01
We explore the intimate connection between spacetime geometry and electrodynamics. This link is already implicit in the constitutive relations between the field strengths and excitations, which are an essential part of the axiomatic structure of electromagnetism, clearly formulated via integration theory and differential forms. We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for specific spacetime geometries. At the foundational level, we discuss the possibility of generalizing the vacuum constitutive relations, by relaxing the fixed conditions of homogeneity and isotropy, and by assuming that the symmetry properties of the electro-vacuum follow the spacetime isometries. The implications of this extension are briefly discussed in the context of the intimate connection between electromagnetism and the geometry (and causal structure) of spacetime.
Dayside merging and cusp geometry
International Nuclear Information System (INIS)
Crooker, N.U.
1979-01-01
Geometrical considerations are presented to show that dayside magnetic merging when constrained to act only where the fields are antiparallel results in lines of merging that converge at the polar cusps. An important consequence of this geometry is that no accelerated flows are predicted across the dayside magnetopause. Acceleration owing to merging acts in opposition to the magnetosheath flow at the merging point and produces the variably directed, slower-than-magnetosheath flows observed in the entry layer. Another consequence of the merging geometry is that much of the time closed field lines constitute the subsolar region of the magnetopause. The manner in which the polar cap convection patterns predicted by the proposed geometry change as the interplanetary field is rotated through 360 0 provides a unifying description of how the observed single circular vortex and the crescent-shaped double vortex patterns mutually evolve under the influence of a single operating principle
DOGBONE GEOMETRY FOR RECIRCULATING ACCELERATORS
International Nuclear Information System (INIS)
BERG, J.S.; JOHNSTONE, C.; SUMMERS, D.
2001-01-01
Most scenarios for accelerating muons require recirculating acceleration. A racetrack shape for the accelerator requires particles with lower energy in early passes to traverse almost the same length of arc as particles with the highest energy. This extra arc length may lead to excess decays and excess cost. Changing the geometry to a dogbone shape, where there is a single linac and the beam turns completely around at the end of the linac, returning to the same end of the linac from which it exited, addresses this problem. In this design, the arc lengths can be proportional to the particle's momentum. This paper proposes an approximate cost model for a recirculating accelerator, attempts to make cost-optimized designs for both racetrack and dogbone geometries, and demonstrates that the dogbone geometry does appear to be more cost effective
Geometric Transformations in Engineering Geometry
Directory of Open Access Journals (Sweden)
I. F. Borovikov
2015-01-01
Full Text Available Recently, for business purposes, in view of current trends and world experience in training engineers, research and faculty staff there has been a need to transform traditional courses of descriptive geometry into the course of engineering geometry in which the geometrical transformations have to become its main section. On the basis of critical analysis the paper gives suggestions to improve a presentation technique of this section both in the classroom and in academic literature, extend an application scope of geometrical transformations to solve the position and metric tasks and simulation of surfaces, as well as to design complex engineering configurations, which meet a number of pre-specified conditions.The article offers to make a number of considerable amendments to the terms and definitions used in the existing courses of descriptive geometry. It draws some conclusions and makes the appropriate proposals on feasibility of coordination in teaching the movement transformation in the courses of analytical and descriptive geometry. This will provide interdisciplinary team teaching and allow students to be convinced that a combination of analytical and graphic ways to solve geometric tasks is useful and reasonable.The traditional sections of learning courses need to be added with a theory of projective and bi-rational transformations. In terms of application simplicity and convenience it is enough to consider the central transformations when solving the applied tasks. These transformations contain a beam of sub-invariant (low-invariant straight lines on which the invariant curve induces non-involution and involution projectivities. The expediency of nonlinear transformations application is shown in the article by a specific example of geometric modeling of the interfacing surface "spar-blade".Implementation of these suggestions will contribute to a real transformation of a traditional course of descriptive geometry to the engineering geometry

Lectures on Algebraic Geometry I
Harder, Gunter
2012-01-01
This book and the following second volume is an introduction into modern algebraic geometry. In the first volume the methods of homological algebra, theory of sheaves, and sheaf cohomology are developed. These methods are indispensable for modern algebraic geometry, but they are also fundamental for other branches of mathematics and of great interest in their own. In the last chapter of volume I these concepts are applied to the theory of compact Riemann surfaces. In this chapter the author makes clear how influential the ideas of Abel, Riemann and Jacobi were and that many of the modern metho

The central theme of this book is the interaction between the curvature of a complete Riemannian manifold and its topology and global geometry. The first five chapters are preparatory in nature. They begin with a very concise introduction to Riemannian geometry, followed by an exposition of Toponogov's theorem-the first such treatment in a book in English. Next comes a detailed presentation of homogeneous spaces in which the main goal is to find formulas for their curvature. A quick chapter of Morse theory is followed by one on the injectivity radius. Chapters 6-9 deal with many of the most re

A variety of scenarios are considered which shed light upon the uses and limitations of classical geometric and topological notions in string theory. The primary focus is on situations in which D-brane or string probes of a given classical space-time see the geometry quite differently than one might naively expect. In particular, situations in which extra dimensions, non-commutative geometries as well as other non-local structures emerge are explored in detail. Further, a preliminary exploration of such issues in Lorentzian space-times with non-trivial causal structures within string theory is initiated.

The patient dignity inventory (PDI) is an instrument to measure dignity distressing aspects at the end of life. The aims of the present study were the translation of the PDI in Greek language as well as to measure its psychometric aspects in a palliative care unit. A back-translation method was obtained at the Greek version. One hundred twenty advanced cancer patients completed the Greek version of the PDI, the Greek hospital anxiety and depression scale, the Greek schedule of attitudes toward hastened death (SAHD-Gr), and the Greek 12-item short form health survey. Confirmatory factor analysis failed to fit to the original instrument's structure and exploratory factor analysis was conducted revealing five factors ("Psychological Distress," "Body Image and Role Identity," "Self-Esteem," "Physical Distress and Dependency," and "Social Support"). The psychometric analysis of the PDI-Gr demonstrated a good concurrent validity, and the instrument discriminated well between subgroups of patients regarding age differences. Cronbach α were between 0.71 and 0.9 showing a good internal consistency. The Greek version of the PDI showed good psychometric properties in advanced cancer patients, supported the usefulness of the instrument assessing the sense of dignity distressing aspects of the terminally ill cancer patients.

Granular flows in constrained geometries
Murthy, Tejas; Viswanathan, Koushik
Confined geometries are widespread in granular processing applications. The deformation and flow fields in such a geometry, with non-trivial boundary conditions, determine the resultant mechanical properties of the material (local porosity, density, residual stresses etc.). We present experimental studies of deformation and plastic flow of a prototypical granular medium in different nontrivial geometries- flat-punch compression, Couette-shear flow and a rigid body sliding past a granular half-space. These geometries represent simplified scaled-down versions of common industrial configurations such as compaction and dredging. The corresponding granular flows show a rich variety of flow features, representing the entire gamut of material types, from elastic solids (beam buckling) to fluids (vortex-formation, boundary layers) and even plastically deforming metals (dead material zone, pile-up). The effect of changing particle-level properties (e.g., shape, size, density) on the observed flows is also explicitly demonstrated. Non-smooth contact dynamics particle simulations are shown to reproduce some of the observed flow features quantitatively. These results showcase some central challenges facing continuum-scale constitutive theories for dynamic granular flows.

Geometric ideas are present in many areas of modern theoretical physics and they are usually associated with the presence of nonlinear phenomena. Integrable nonlinear systems play a prime role both in geometry itself and in nonlinear physics. One can mention general relativity, exact solutions of the Einstein equations, string theory, Yang-Mills theory, instantons, solitons in nonlinear optics and hydrodynamics, vortex dynamics, solvable models of statistical physics, deformation quantization, and many others. Soliton theory now forms a beautiful part of mathematics with very strong physical motivations and numerous applications. Interactions between mathematics and physics associated with integrability issues are very fruitful and stimulating. For instance, spectral theories of linear quantum mechanics turned out to be crucial for studying nonlinear integrable systems. The modern theory of integrable nonlinear partial differential and difference equations, or the `theory of solitons', is deeply rooted in the achievements of outstanding geometers of the end of the 19th and the beginning of the 20th century, such as Luigi Bianchi (1856-1928) and Jean Gaston Darboux (1842-1917). Transformations of surfaces and explicit constructions developed by `old' geometers were often rediscovered or reinterpreted in a modern framework. The great progress of recent years in so-called discrete geometry is certainly due to strong integrable motivations. A very remarkable feature of the results of the classical integrable geometry is the quite natural (although nontrivial) possibility of their discretization. This special issue is dedicated to Jean Gaston Darboux and his pioneering role in the development of the geometric ideas of modern soliton theory. The most famous aspects of his work are probably Darboux transformations and triply orthogonal systems of surfaces, whose role in modern mathematical physics cannot be overestimated. Indeed, Darboux transformations play a central
