The pearls and pitfalls of skull trephination as described in the Hippocratic treatise "On Head Wounds"

The purpose of our current study is to describe the guidelines regarding trephination as suggested in the Hippocratic writer's book, "Peri ton en cephali traumaton" ("On Head Wounds"). The ancient Greek text was reviewed as well as two English translations. The Hippocratic author described the indications, timing, and techniques of trephination for patients with head injury. He emphasized that attention should be paid to the details of the employed technique. He also commented on the difference of skull thickness at different anatomical sites and also between different age groups. The Hippocratic recommendations provided details for the performance of trephination by the ancient Greek physicians that are still considered important in modern neurosurgery.     

Identity and socio-economic mobility in Venetian Crete: the evolution of a citizen family (sixteenth century)

This study focuses on the socio-economic dynamics in Crete under Venetian rule, particularly in the sixteenth century, a critical period for the power of the Republic of Venice in the eastern Mediterranean. There is an attempt to approach these processes by examining the evolution of a Cretan family named Episcopopulo, which originated from the middle social stratum, the so-called cittadini (citizens). The essay tries, after outlining the socio-political characteristics of the intermediate social group, to illuminate aspects of the history of this family, who strove to find its way in an environment marked by fermentations and changes in the political, financial, ideological and social field. The study, among other things, examines the various professional activities of the family members and the practices they utilized to achieve a decisive improvement in their financial status. It also highlights the strategies they employed to their rise in the social hierarchy, as well as their persistent efforts, after acquiring a title of nobility, to retain and increase their wealth and to enhance their role in the public sphere.     

A 3D digital workflow for archaeological intra-site research using GIS

Across a range of archaeological projects in Northern Greece, a context-based system, which has much in common with similar stratigraphic methods applied elsewhere in the world, is in use to record the excavation process. Here, we discuss a formal data model and complete digital workflow for the documentation of this process in 3D using the prehistoric site of Paliambela Kolindros, Greece, as a case study. The entire digital process has the advantage of being implemented on a single software platform. In addition, the combination of formal ontology and custom object-oriented programming enables a suite of techniques for exploratory data analysis and stratigraphic interpretation.     

The Effects of Regional Capital Subsidies on Productivity Growth: A Case Study of the Greek Food and Beverage Manufacturing Industry*

Abstract. Capital subsidies form a major instrument of industrial and regional policy for economically developed countries all over the world, including many European Union and Organisation for Economic Cooperation and Development countries. Research findings have challenged the effectiveness of capital subsidies in assisting productivity growth. This paper treats capital subsidies as a new input and estimates a stochastic production frontier that is not bound by the restrictions imposed by approaches used in previous research works. It is shown that capital subsidies affect total factor productivity growth through technical change and not through scale efficiency, while the disadvantaged location of firms affects technical efficiency.     

The European Policy on Water Use at the Urban Level in the Context of the Water Framework Directive. Effectiveness,Appropriateness and Efficiency

The current European policy on water resources use in cities is undergoing radical reform in an attempt to confront the water quality problems and the dramatically intensified water scarcity. Among the most elaborate documents concerning current water policy is the Water Framework Directive (WFD), which spells out the targets of water policy at the European level. The confrontation of water scarcity, deterioration in quality, and the reduction in costs of the water supply industry emerge as decisive principles of the new European policy on water use in cities. These targets are currently assimilated in the agendas of national water policies in almost all European countries. To achieve these objectives several policy instruments have been applied in Europe. The more prevailing instruments are: demand management, privatization of water companies and efficient/full cost pricing of water use. The present article aims at systematically evaluating the effectiveness and efficiency of the current water policy for urban systems, by examining the coherence of its instruments as well as their appropriateness for achieving the policy's targets. To start with, the paper presents an elementary economic analysis of the current water policy. The effects of the most common policy instruments are systematically traced in the framework of economic analysis. Next, three indicative case cities are presented and examined. As it turns out, however, the results of the implementation of the main instruments are contradictory. This drastically reduces the effectiveness of the water policy. We indicate that these contradictory effects are inherent in the water policy and originate in the lack of appropriate social processes and institutions for the management of natural resources.     

On the provenance and manufacture of red-slipped fine ware from ancient Cassope (NW Greece): evidence by X-ray analytical methods

Energy-dispersive X-ray fluorescence spectroscopy was used to characterize red-slipped pottery (2nd–1st century BC) from ancient Cassope, north-western Greece. The compositional data were statistically treated by principal component analysis and chemical groups were established, representing locally produced and imported items. Mineralogical investigation by X-ray diffraction indicated firing temperatures in the range from 850 to 1000 °C for most of the sherds, while one group consisted of over-fired items, possibly in excess of 1050 °C. The morphology and elemental composition of the ceramic bodies and surface slips were examined through scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy. The analyses revealed that different pottery groups exhibit surface slips of different nature, in terms of thickness, degree of vitrification and elemental composition. Overall, the diversity in technological characteristics of the examined sherds is indicative of the socio-economic conditions prevailing in Cassopaea during the late Hellenistic period.
