Robust Performance-Based Design Optimization of Steel Moment Resisting Frames

The concept of performance-based design is considered in the framework of Robust Design Optimization (RDO) for the design of steel structures. The RDO problem is treated as a two-objective optimization problem where the initial construction cost and the variance of the maximum interstorey drift for the 10% in 50 years hazard level are considered as the problem objectives to be minimized. The structural performance is evaluated by means of the reliability demand and resistance methodology of the FEMA-350 guidelines in order to take into account both uncertainty and randomness in a consistent manner. The structure is designed to respond for different levels of seismic hazard levels with a desired confidence. The limit-state damage cost is used as a measure for the assessment of selected designs that have been obtained through the proposed RDO formulation. The non deterministic finite element problem encountered, is solved using the Monte Carlo Simulation method. The NSGA-II algorithm has been combined with the Evolution Strategies optimization algorithm for solving the two-objective optimization problem at hand.     

The Influence of Masonry Infill Walls in the Framework of the Performance-Based Design

In this article, a performance-based seismic design (PBD) methodology is proposed for the design of reinforced concrete buildings, taking into account the influence of infill walls. Two variants of the PBD framework are examined: The first is based on the non-linear static analysis procedure (NSP) while the second relies on the non-linear dynamic analysis procedure (NDP). Both design approaches are compared in the context of structural optimization with reference to the best possible design achieved for each case examined. Life-cycle cost analysis is considered a reliable tool for assessing the performance of structural systems and it is employed in this study for assessing the optimum designs obtained. The optimization part of the problem is performed with an Evolutionary Algorithm while three performance objectives are implemented in all formulations of the design procedures. The two most important findings can be summarized as follows: (i) if structural realization follows the design assumptions, then total expected life-cycle cost of the three type of structures, bare, fully infilled and open ground story, is almost the same and (ii) if an open ground story building is designed as bare or as fully infilled frame, real performance will be much worse than anticipated at the design stage.     

Integration of geophysical surveys,ground hyperspectral measurements,aerial and satellite imagery for archaeological prospection of prehistoric sites: the case study of Vésztő-Mágor Tell,Hungary

An integration of geophysical surveys, ground hyperspectral data, aerial photographs and high resolution satellite imagery for supporting archaeological investigations at the multi-component Vészt?-Mágor Tell, located in the southeastern Great Hungarian Plain, is presented in this study. This is one of the first times that all these techniques have been combined and evaluated for retrieving archaeological information. Geophysical explorations, specifically magnetic gradiometry and ground penetrating radar methods, have revealed shallow linear anomalies and curvilinear rings at the Tell. The use of remote sensing images has confirmed the diverse anomalies with respect to geophysics through photointerpretation, radiometric and spatial enhancements. Moreover, several indices from ground hyperspectral data also have revealed stress vegetation anomalies. These integrated results were used to map the main areas of archaeological interest at the Vészt?-Mágor Tell and plan future excavations. It was found that these multiscalar data can be used efficiently for detecting buried archaeological features.     

The European Union Higher Education Policy and the Stake of Regionalization

This paper attempts to explore the underlying nature and terms of Higher Education policy. Higher Education policy cannot be viewed outside the changing conditions of the state especially when the inquiry centres on Europe. In the European context, policy making, in order to be efficient, seems to be conducted on two levels, the supranational and the regional. This change in the structure of Higher Education policy making can be considered as an outcome of globalization and the current market economy. The EU's Higher Education policy may be expected to go beyond the national into the supranational level of cooperation with the launching of new initiatives resulting from the Bologna Process and the European Higher Education Area. These initiatives are reshaping the role and responsibilities of Higher Education Institutes towards society and the market. The new role that these institutes are called upon to play indicates a clear tendency towards dissemination and the growing need for cooperation at the regional level.     

Ethnoarchaeological study of phytolith assemblages from an agro-pastoral village in Northern Greece (Sarakini): development and application of a Phytolith Difference Index

Phytolith assemblages are analysed in an ethnographic agro-pastoral community in Northern Greece. A new method for analyzing the data, combined with the concentrations of phytoliths per gram sediment, helps to differentiate diverse uses of space in the village. The Phytolith Difference Index (PDI) contrasts the phytolith assemblages in sediment samples from the region around the village least affected by human activities with those in the village and its immediate surroundings. The PDI reveals that many of the samples are dominated by the input of the stalks of the domestic cereal, rye, which is used for food, animal fodder and roof thatching. The PDI also differentiates between dung from mules or donkeys with dung from free ranging cows and goats. Activity areas analysed include storage areas, stabling areas, animal enclosures, floors from living areas that were repeatedly swept, hearths and open areas between structures. The combined use of the PDI, together with phytolith concentrations and phytolith morphotype analyses, may prove to be useful for deciphering activity areas in archaeological sites of not only agro-pastoralists, but also pastoralists and hunter–gatherers.     

The phytolith archaeological record: strengths and weaknesses evaluated based on a quantitative modern reference collection from Greece

The phytolith record from archaeological strata is a powerful tool for reconstructing aspects of past human behaviour and ecology. Considerable insights into the problems and potentials of this record can be obtained by studying phytoliths in modern plants. We prepared a phytolith reference collection of modern plants mostly from northern Greece that includes quantitative information on phytolith concentrations (number of phytoliths per gram dry organic material) and morphological assemblages. Here we analyse this reference collection with the aim of evaluating the strengths and weaknesses of the archaeological phytolith record. The reference collection comprises 62 different plant taxa. Of them, 28 are trees, 1 conifer, 10 shrubs and 1 herb, 3 domesticated annual legumes and 19 monocotyledons. We demonstrate quantitatively the extent to which woody species, legumes and fruits of dicots contribute only small amounts of phytoliths to the sediments per unit tissue dry weight, while leaves of trees and shrubs produce significant amounts of phytoliths and grasses are prolific phytolith producers. We compare the data of this reference collection with a similar reference collection from another Mediterranean ecosystem (Israel). The comparison indicates that some aspects of phytolith production are probably genetically controlled, whereas others are environmentally controlled. We note that despite the fact that woody species produce few phytoliths per gram of tissue, their record can be most informative when taking into account other properties of the sediments. We also note that jigsaw puzzle-shaped phytoliths normally form in plants that grow in humid conditions, but may form in arid environments when the plants are irrigated. This study clearly shows the extent to which some plants can be under-represented and others over-represented in the phytolith record. Knowing the extent of this bias can greatly improve our interpretation of the phytolith record.     

Firm relocation in times of economic crisis: evidence from Greek small and medium enterprises’ movement to Bulgaria, 2007–2014

This paper examines firm relocation in the aftermath of the 2007 global economic crisis. In particular, the paper analyses the unprecedented recent increase in the movement of small and medium enterprises (SMEs) from Greece to Bulgaria using original insights by a survey of 103 Greek companies in Bulgaria. The findings suggest a reconsideration of the existing literature on firm mobility in order to explain the post-crisis movement of Greek SMEs. Entrepreneurs perceived firm relocation as a necessity, while, contrary to the existing literature, labour cost does not appear to have significantly influenced firm exit from Greece, the level of demand was highlighted as more important compared with the literature findings and access to external finance emerged as a major factor. Important among elements that attracted businesspeople to Bulgaria were low taxation and geographical proximity to Greece. The present analysis thus challenges the significance of firm relocation determinants in the literature.     

The invasion complex: the abject other and spaces of violence

This article examines how the image of the refugee has been defined through the fear of the other, and how the mechanisms of detention have transformed the conditions of belonging. I examine the contemporary geopolitical forces propelling the rise of a new authoritarianism, growing border anxieties and hostility towards refugees, and argue that these emerging shifts provoke an urgent need for a new conceptual framework to understand the dynamics of contemporary global flows and concepts of belonging. I introduce what I call the ‘invasion complex’, a new conceptual hybrid that draws upon elements of psychoanalytic theory and complex systems theory, and Giorgio Agamben's analysis of sovereignty and ‘the camp’, to explain heightened border anxieties and the legitimization of violence towards the Other. I consider the value, applications and limitations of Agamben's analysis, and contend that both the state‐centric moral debate on the refugee crisis, and Agamben's method of privileging political agency in terms of sovereign power, tend to discount the role of complexity. Drawing on the Australian political and public discourse on refugees, and the 2001 Tampa crisis, I argue that the hostile reactions can be traced to a complex interplay between old phobias and new fantasies. I conclude by urging the need to move beyond nation state centric critiques of racism, and propose the development of a new paradigm — a potential politics that recognizes the complex dynamics of global flows, and which opens the way for a discourse of hope based on the rights of the human being, rather than the citizen.
