ACTIVE GEOTHERMAL SYSTEMS IN THE CONTINENTAL RIFT ZONES OF THE MENDERES MASSIF, WESTERN ANATOLIA, TURKEY
Authors: Özgür N. , Arife Çalışkan T.
Published: July 2017

The active geothermal waters of Kızıldere, Bayındır, and Salihli in the continental rift zones of the Büyük Menderes, Küçük Menderes and Gediz represent typical examples in the study area. The meteoric waters in the drainage areas of the rift zones percolate at NE-SW and/or NW-SE trending fault zones and permeable clastic sediments into the reaction zone of the roof area of a magma chamber situated in a probable depth of up to 5 km where meteoric fluids are heated by the cooling magmatic melt and ascend to the surface due to their lower density caused by convection cells. The volatile components of CO2, SO2, HCl, H2S, HB, HF, and He out of the magma reach the geothermal water reservoir where an equilibrium between altered rocks, gas components, and fluids performs. Thus, the geothermal waters ascend in the tectonical zones of weakness at the continental rift zones of the Menderes Massif in terms of hot springs, gases, and steams. These fluids are characterized by high to medium CO2, H2S and NaCl contents.

Authors: Papachristou M. , Arvanitis A. , Kolios N.
Published: July 2017

This paper describes the results of the preliminary surface geothermal exploration conducted by IGME in the basin of Katerini (Northern Greece). It mainly regards temperature measurements at the wellhead of 73 wells and in the interior of five boreholes, as well as sampling and chemical analyses from 18 selected sites. Based on the collected data, three sub-regions of geothermal interest can be distinguished, the most important of which is the area of Kato Agios Ioannis (to the south of the basin), with temperatures around 27oC at the depth of 340m. Nonetheless, the detailed geothermal investigation of this basin requires further systematic research as well as the drilling of at least one deep geothermal exploration borehole.
DESALINATION AND BOREHOLE CONSTRUCTION FOR ABSTRACTION OF SALINE WATER AND CHANNELING BRINE DISPOSAL
Authors: Sampatakakis P. , Manthos G. , Kepas A.
Published: July 2017

The purpose of this research is to present all the technical details, but also the scientific criteria according to which there is the possibility to make a borehole for the extraction of the saline water and channeling of brine in another borehole. This methodology has purpose to prove that this way of extraction of saline water (or sea water) through the borehole and the channeling of the remain into another one has multiple assets comparing to the classical method of the direct extraction and return of the residue into the sea. These assets are considered to be better because of the extraction which may be in the inland, hypsometrically more advantageous. Also, the channeling of the brine disposal in a nearby borehole is safer from an environmental point of view because  does not disturb the flora and fauna in the benthic zone of the marine space, but also a less expensive solution than channeling it straight into the sea. In any case, it is a necessary presumption that the hydrogeologic conditions in the area where the work is taking place to ensure a high factor of permeability and hydraulic connection with the sea area. The application of this technique was completed with some success in the case of Agistri Island (and homonymous municipality) which is located in the Saronic Gulf, southwest of Salamis Island. Although the distance between the two boreholes should be larger in order to prevent the risk of dynamic input of brine disposal to the borehole extraction because of the radius of influence, which would destroy the osmosis membranes. After the appropriate evaluation of the test pumping elements, this was ensured by placing the appropriate sensors of salinity.

Published: July 2017

This study refers to hydrogeological conditions that dominate in the closed basin of Vagia of Viotia with emphasis on groundwater quality. It highlights the environmental problem of the region, associated with floods, phenomenon which occurs every year and lasts throughout the wet season. This, results in flushing undesirable substances from the territories of intensely cultivated area and the penetration into the groundwater of Neogene- Quaternary and carbonates aquifers. Qualitative charge of groundwater is reflected in the high concentrations of the ions Na+:22,2-133,4 mg/l, K+:0,3-12,0mg/l, SO4 2-:2,1-68,9mg/l, Cl-:24,8-241,1mg/l, NO3-:13,6-67,0mg/l, NH4 +:0,01-1,75mg/l, PO43-:0,03-0,94mg/l as well as the strong presence of heavy metals (Fe, Mn, Zn, Ni, Co, Cu and Cr). Qualitative charge of groundwater is attributed to natural (geogenic) and anthropogenic factors.

Published: July 2017

Floods are one of the most common natural hazards in global range and could threat the human life, health, environment and infrastructure. The aim of this paper is the estimation and the delimitation of the likely flood hazard zones, for different rainfall intensities in the upper part of Gallikos river basin (central Macedonia) according to the European directive 2007/60. For the analysis of the meteorological data and the construction of flood zone maps, HYDROGNOMON, HEC-HMS, HEC-RAS free software packages were used. The thematic maps were constructed with ESRI GIS. The results are depicted in flood inundation maps, delimitating and visualizing the scale of the flood hazard effect in the area. The construction of flood prediction models is a very useful tool towards the direction of the design of an efficient flood management framework.
NEW DATA REGARDING THE GROUND WATER LEVEL CHANGES AT THE AMYNTAIO BASIN- FLORINA PREFECTURE, GREECE
Authors: Tzampoglou P. , Loupasakis C.
Published: July 2017

The site investigated is the Amyntaio basin where a productive semi-confined aquifer is developed at the quaternary deposits. In the present study, the piezometric curves which have been extracted before the beginning of the mine activity (1992), were compared with the recent ones (2015), aiming to study their diachronic changes. From the subtraction of the two aforementioned piezometric surfaces, a significant ground water drawdown that reaches 70 m near the mine was observed. This drawdown, during the last decades, proves that the aquifer has been overexploited by both the mine of PPC -to protect the slopes and to prevent the water outflow in the mine- and the wells for irrigation purposes. The level drop extends, on the west, to the villages of Valtonera and Anargyroi and the underground water flow directs towards the mine. The Amyntaio mine can be described as a well with a diameter up to a few kilometers. The interaction of the groundwater level drawdown with the intense fragmentation and the geotechnical characteristics of the geological formations of the region triggered extensive land subsidence phenomena damaging numerous villages, infrastructures and extensive farmlands.
FUTURE DROUGHT PROJECTION FOR THE GREEK REGION
Authors: Anagnostopoulou C.
Published: July 2017

Drought is one of the most important factors of change. The epi-drops drought in one area are complex because they simultaneously affect many areas, such as climate, agriculture, the economy and in general the structure of society. This study deals only with the meteorological drought, particularly considering the phenomenon of drought through the index Standardized Precipitation Index (SPI). The Greece is characterized by frequent drought episodes that often exceed 10 consecutive days of drought (dry spells). Also, in recent years the area probably climate models have been used in a wide study of the impact of climate change in different regions on the planet. Rainfall data from five regional climate models (RCMs) have been used to calculate the SPI index in the Greek area, the reporting period and two subsequent periods by the end of the 21st century. All models show a decreasing trend of the SPI median during the period studied. For the first future period 2021-2050, there is a clear signal for a dry decade towards the end of the period that is most apparent in southern and island regions. On the other hand, in the second future period 2071-2100, there is an increasing trend resulting to normal or wetter years.
INVESTIGATION OF SINKHOLE AREAS BY THE USE OF ELECTRICAL RESISTIVITY TOMOGRAPHY: THE CASE OF PEDINI IN IOANNINA, GREECE
Authors: Fikos I. , Vargemezis G. , Kapeti F. , Avramidou E. , Stylianou T.
Published: July 2017

The Electrical Resistivity Tomography (ERT) method was used in order to study the karstic system in Pedini area (close to the city of Ioannina, West Greece) νthat is related with sinkholes whereby the drainage of the surficial water was possible. The last five years floods are causing major problems in the area, since, the urbanization of the basin, in which the construction of a large highway is included, along with the increase of rainfalls produced a huge amount of water which the sinkhole was not able to drain any more. The geophysical survey showed that the depth of the sinkholes is about 30 meters, proving their limited capacity to drain the basin to the desired level. At the same time, a fractured zone of high porosity has been revealed in the vicinity of the sinkholes.This zone can be used as to increase the capability of the sinkholes to drain the flood water.
PRELIMINARY SHEAR-WAVE SPLITTING RESULTS IN THE BROADER AIGION AREA (GREECE) DURING 2013
Authors: Kaviris G. , Spingos I. , Kapetanidis V. , Papadimitriou P.
Published: July 2017

An anisotropic upper crust has been revealed in the W. Gulf of Corinth with potentially changing properties. During 2013, a unique opportunity to conduct a shear-wave analysis was presented, as a combination of the significantly increased seismicity in the area, including a seismic swarm between May and August, and the existence of local seismological networks. The Hellenic Unified Seismological Network (HUSN) and the Corinth Rift Laboratory Network (CRLN) provided invaluable data during the unrest period. While shear-waves travel through an anisotropic medium, the splitting phenomenon takes place and, as a result, their propagation is characterized by two discernible components: the fast (Sfast) and the slow (Sslow) one, which arrives to the station in a subsequent temporal point. Modern advances in seismology and geophysics have rendered shear-wave splitting a valuable tool in determining properties of the anisotropic propagation media. One of the predominant causes of this phenomenon is the existence of microcracks throughout the upper crust. The current study presents results for 8 stations from 535 analyzed events that are in agreement with the anisotropy models of EDA and APE.

Published: July 2017

The conditional probabilities method is considered to be an alternative approach in order to estimate the earthquake hazard. For this purpose, this technique was applied to the western side of South America, one of the most seismogenic regions of the world. The method is applied in six pre-determined zones which covered the whole examine area. The occurrence of the earthquakes as a function of time was assessed, using the conditional probabilities technique. The Kolmogorov-Smirnov test was applied in order to determine the distribution followed by the inter-arrival times between the successive past events. The test shows that the lognormal is the best fit distribution, for the scope of the present work. The obtained results are in good accordance to the method applied. High probabilities are estimated for events with Mw7.0. For the whole western part of South America, there is a probability about 64% for an earthquake occurrence with magnitude M8.0, during a time period of 20 years. Higher probability (≈73%) was estimated for a time period of 50 years and for an earthquake of magnitude M8.5. This is clearly showed for the event of 1960, where the next (a posteriori procedure) earthquake of M=8.8 occurred on 2010.

Published: July 2017

During a 12-month period (August 1998 - June 1999), a dense microseismic network of 44 portable seismographs, was installed in Epirus - Northwestern Greece, by the Seismological Laboratory, of the University of Patras and recorded 1368 earthquakes. We selected a subset of 200 well recorded events, with duration magnitude ranging from 1.61 to 2.92 and focal depths ranging from a few hundred meters to 35km; the majority was in the 0-10km range. This study uses this high quality dataset to (i)calculate the earthquake spectra and source parameters; (ii) perform linear regression between Seismic Moment (M0) and the source parameters Source Radius (r), Stress Drop (Δσ) and Displacement (s); (iii) correlate source parameter’s distribution with the tectonics of the area. Finally, we compare the derived empirical laws with similar studies.

Published: July 2017

The Mid-Atlantic Ridge (M-AR), which runs along the centre of the Atlantic Ocean, is one of the best known divergent boundaries. Seismic studies have been a crucial factor in deciphering the structure of the oceanic crust. For their performance a necessary prerequisite is the compilation of a reliable earthquake catalog of the broader area. In this study, an attempt was made to create an earthquake catalog of M-AR that could become a useful “tool” for large-scale seismological studies of this region. For this reason a very large sample of data from several seismological centers, as well as from already published catalogs of strong earthquakes, was collected and examined. ISC was considered as the main reference agency, while as reference magnitude scale the moment magnitude scale, MW was adopted. The main goal was to identify and organize the best and most recent information available for earthquakes falling within the time window 1900-2014 and the space window bounded by the extended coordinates ~ 81 (N) to -51 (S) and 10 (E) to ~ -50 (W). After magnitude homogenization, check of focal depths and definition of completeness magnitude, a reliable and homogeneous earthquake catalog of M AR consisting of 14,211 events was created, available for any seismological use and further study.

MODELLING THE ENERGY RELEASE PROCESS OF AFTERSHOCKS
Authors: Gospodinov D.
Published: July 2017

A stochastic model for the study of Benioff strain release during aftershock sequences is suggested. The stochastic model is elaborated after a compound Poisson process and is applied on data of the M7.1 Ocober 18, 1989 Loma Prieta aftershock sequence in northern California, USA. The temporal evolution of the number of events is first modelled by the Restricted Epidemic Type Aftershock Sequence (RETAS) model and then the identified best fit model is incorporated in the energy release analysis. The suggested model is based on the assumptions that there is no relation between the magnitude and the occurrence time of an event first and second, that there is no relation between the magnitude of a certain event and magnitudes of previous events. The obtained results from the examination of the energy release reveal that the suggested model makes a good fit of the aftershock Benioff strain release and enables a more detailed study by identifying possible deviations between data and model. The real cumulative energy release values surpass the expected model ones, which proves that aftershocks, stronger than forecasted by the model, are clustered at the beginning of the Loma Prieta sequence.
SEISMOGENIC NODES DEFINED BY PATTERN RECOGNITION IN THE CENTRAL PART OF THE ALPINEHIMALAYAN BELT
Authors: Novikova O. , Gorshkov A.
Published: July 2017

Information on the areas prone to the strongest earthquakes in a region is very important for knowledgeable seismic hazard and risk assessment. We consider the central part of the Alpine-Himalayan Belt (Caucasus–Kopet Dagh-Alburz) for the recognition of seismogenic nodes capable of M7+ earthquakes. The nodes formed around the intersections of the fault zones are viewed as objects of recognition which have been described by the common set of geologic, geomorphologic and geophysical parameters. 150 nodes out of 510 ones delineated in the Caucasus Kopet Dagh- Alburz region were recognized prone for earthquakes M7+. We have recognized a number of capable nodes where earthquakes M7+ have not yet been recorded.
STRESS EVOLUTION ONTO MAJOR FAULTS IN MYGDONIA BASIN
Authors: Gkarlaouni G.C. , Papadimitriou E.E. , Kilias A.Α.
Published: July 2017

Stress transfer due to the coseismic slip of strong earthquakes, along with fault population characteristics, constitutes one of the most determinative factors for evaluating the occurrence of future events. The stress Coulomb (ΔCFF) evolutionary model in Mygdonia basin (N.Greece) is based on the coseismic changes of strong earthquakes (M≥6.0) from 1677 until 1978 and the tectonic loading expressed with slip rates along major faults. In the view of stress transfer mechanisms, ΔCFF is also calculated onto fault planes, along with the segmented fault zone from Thessaloniki to Gerakarou and N.Apollonia (TG-NAp FZ). Normal fault segments bound the basin from the south and currently compose the most active neotectonic zone. The association of the spatial distribution of seismicity (2000-2014) with the stress enhanced areas is also investigated. Results demonstrate that the earthquake locations are strongly influenced by the stress transfer from past strong earthquakes and their focal properties. Since the stress build-up occurs fast, results are discussed in terms of hazard assessment by defining potential locations for future events.

Published: July 2017

The contribution of GPS networks in monitoring seismic events is important because they can provide a direct geometrical information on the Earth's crust using satellite observations In this study position displacements of permanent GPS stations are determined due to intense seismic events in the North Aegean area after the strong earthquake on May 24, 2014. The horizontal coseismic displacements for the Samothrace Island were estimated at 9.4 cm and for Lemnos Island at 5.2 cm respectively. A study period of seven days was enough to show that the deformation evolved into two days.

Published: July 2017

The ground motions in the Kalochori region (well known for its subsidence history during the 2nd half of 20th century) were investigated by NOA using a mobile GNSS (GPS) network, comprising 18 stations. The network was measured four (4) times during the period October 2013 - April 2015 under the framework of the research project INDES-MUSA. Our GPS measurements were processed with GAMIT software and show vertical (ITRF 2008) motions ranging from -2 cm to +2 cm (i.e. just above the margins of measurement error) with the exception of the Kalochori dam where an uplift of 2-5 cm was observed. We also found no evidence for local (non-tectonic) motions and/or interseismic strain.
THE 2014 MW 6.9 NORTH AEGEAN TROUGH (NAT) EARTHQUAKE: SEISMOLOGICAL AND GEODETIC EVIDENCE
Authors: Saltogianni V. , Gianniou M. , Taymaz T. , Yolsal-Çevikbilen S. , Stiros S.
Published: July 2017

A strong earthquake (Mw 6.9) on 24 May 2014 ruptured the North Aegean Trough (NAT) in Greece, west of the North Anatolian Fault Zone (NAFZ). In order to provide unbiased constrains of the rupture process and fault geometry of the earthquake, seismological and geodetic data were analyzed independently. First, based on teleseismic long-period P- and SH- waveforms a point-source solution yielded dominantly right-lateral strike-slip faulting mechanism. Furthermore, finite fault inversion of broad-band data revealed the slip history of the earthquake. Second, GPS slip vectors derived from 11 permanent GPS stations uniformly distributed around the meizoseismal area of the earthquake indicated significant horizontal coseismic slip. Inversion of GPS-derived displacements on the basis of Okada model and using the new TOPological INVersion (TOPINV) algorithm permitted to model a vertical strike slip fault, consistent with that derived from seismological data. Obtained results are consistent with the NAT structure and constrain well the fault geometry and the dynamics of the 2014 earthquake. The latter seems to fill a gap in seismicity along the NAT in the last 50 years, but seems not to have a direct relationship with the sequence of recent faulting farther east, along the NAFZ.

Published: July 2017

Remote Sensing and photogrammetric techniques have always been used in geological applications. Current advancements in the technology behind Unmanned Aerial Vehicles (UAVs), in accordance with the consecutive increase in affordability of such devices and the availability of photogrammetric software, makes their use for large or small scale land mapping more and more popular. With the UAVs being used for mapping, the problems of increased costs, time consumption and the possible accessibility problems -due to steep terrain-, are all solved at once. In this study, a custom-made UAV with 2 cameras onboard, is used to monitor two complex –regarding their topography- regions in Western Greece. One open pit limestone mine and a landslide occurring on sandy-clayous sediments. Both regions were mapped using surveying instruments like tachymeters and geodetic GPS, as well as using the aforementioned UAV system. 3D models of both regions were created using off-the-shelf photogrammetric software. For the creation of the 3D models, multiple targets were placed on the ground, to indicate GCPs with precisely known coordinates that could be identified in the high-resolution air photos, in order to maintain low Root Mean Square Error, while creating the DSMs and Orthophotos. In addition, the fish-eye effect caused by the cameras’ wide-angle lens was taken into consideration, regarding whether or not it affects the models’ overall geometric accuracy. Finally, the 3D models were compared to the survey measurements and the results are presented in this paper.

Published: July 2017

The long term change of the shoreline is a phenomenon, which is factored in the design of construction projects along the coastal zone. This study presents a methodology that aims to quantify the shoreline displacement rate. The described methodology involves the interpretation of different remote sensing data types, which make up a quite dense time series of representations for the coastline spanning from 1987 to 2012. The representation of the shoreline is based on geometrically corrected (ortho-rectified), historical, analogue, panchromatic, high resolution aerial photos of the area (1987, 1996) and latest generation, digital, multispectral, high resolution satellite images (2000, 2008, 2012). In all cases the images were digitally processed and optically optimized in order to produce a highly accurate representation of the shoreline in each time period. All the data were imported in a Geographic Information System platform, where they were subjected to comparison and geo-statistical analysis. A large number of sections perpendicular to the coast (every 100 meters) was drawn and the relative motion of the coastline was calculated for each of them. The average rate of the calculated erosion is in the order of 24mm/year whilst extreme rates of 1m/year were also observed in specific positions.

The author suggests forming professional communicative competence, not only within the discipline “Russian language and Standard of Speech”, but also to include the communicative blocks of profi le orientation in the cycles of General and professional disciplines, and program practices in the framework of implementation of the basic educational program. This is due to the fact that in the training plan there are not linguistic disciplines (except “Russian language and Standard of Speech”) aimed at building these competencies.
Conseillers scélérats et mauvais gouvernement: le roi d’Aragon, ses conseillers et le conseil à la fin du XIVe siècle
Authors: Beauchamp Alexandra
Published: July 2017

Cet article constitue le préambule d’une analyse du gouvernement par conseil, tel que le roi d’Aragon l’applique à la fin du xive siècle. Il montre combien lors des Cortes generales de Monzón, en 1383, les sujets contestent la place et les décisions des conseillers royaux et remettent en cause la façon dont le gouvernement par conseil s’exerçait sous le règne de Pierre le Cérémonieux. De fait, cet exercice du pouvoir diffère radicalement de la façon dont le roi avait théorisé l’intervention de ses conseillers. L’examen des ordonnances royales (Ordinacions de la Casa i Cort, 1344) souligne en effet la latitude normalement assez réduite qui devait être la leur et la façon dont leur parole et leur action devaient soigneusement être encadrées.
Vidas enfrentadas: Pere Maça de Liçana y Eximèn Pérez de Corella. Enemistad personal, rivalidad señorial y conflictos políticos en el reino de Valencia (1420-1450)
Authors: López Rodríguez Carlos
Published: July 2017

Entre 1420 y 1450, los nobles valencianos Eximèn Pérez de Corella y Pero (o Pere) Maça de Liçana mantuvieron duros enfrentamientos, algunos armados, entre ellos y a través de sus vasallos, fundamentalmente en las comarcas del sur del reino de Valencia, pero con ramificaciones que se extendieron a las instituciones de la Corona. Estos conflictos surgían de la rivalidad entre una familia de barones de rancia estirpe en declive (los Maça de Liçana) y otra de caballeros recientemente ennoblecidos (los Corella) que con sus servicios a la nueva dinastía Trastamara crecían en fortuna y poder. En estos enfrentamientos convergían rivalidades jurisdiccionales y por el dominio territorial, enemistades personales y envidias sociales, que acabaron tomando un cariz político y que son reflejo de la cultura y acción política de la nobleza valenciana en la primera mitad del siglo XV. Sus actitudes se definían por su posicionamiento ante el servicio al soberano y el favor del rey. Respondían, pues, a dos pautas de comportamiento muy características de la nobleza del siglo XV en los estadios inmediatamente anteriores a la consolidación de una monarquía absoluta.
Online Shopping and Social Media: Friends or Foes?
Authors: Zhang Yuchi , Trusov Michael , Stephen Andrew T. , Jamal Zainab
Published: July 2017

As social network use continues to increase, an important question for marketers is whether consumers’ online shopping activities are related to their use of social networks and, if so, what the nature of this relationship is. On the one hand, spending time on social networks could facilitate social discovery, meaning that consumers “discover” or “stumble upon” products through their connections with others. Moreover, cumulative social network use could expose consumers to new shopping-related information, possibly with greater marginal value than the incremental time spent on a shopping website. This process may therefore be associated with increased shopping activity. On the other hand, social network use could be a substitute for other online activities, including shopping. To test the relationship between social network use and online shopping, the authors leverage a unique consumer panel data set that tracks people's browsing of shopping and social network websites and their online purchasing activities over one year. The authors find that greater cumulative usage of social networking sites is positively associated with shopping activity. However, they also find a short-term negative relationship, such that immediately after a period of increased usage of social networking sites, online shopping activity appears to be lower.
A Probit Model with Structured Covariance for Similarity Effects and Source of Volume Calculations

Published: July 2017

Distributional assumptions for random utility models play an important role in relating observed product attributes to choice probabilities. Choice probabilities derived with independent errors have the property of independence of irrelevant alternatives, which often does not match observed substitution behavior and leads to inaccurate calculations of source of volume when new entrants are introduced. In this article, the authors parameterize the covariance matrix for a probit model so that similar brands in the preference space have higher correlation than dissimilar brands, resulting in higher rates of substitution. They find across multiple data sets that similarity based on overall utility, not just attributes, defines products as similar with heightened rates of substitution. The proposed model results in better in-sample and predictive fits to the data and more realistic measures of substitution for a new product introduction.

Die Maximierung der Nutzung wie auch die Umnutzung von Flächen für neue Serviceangebote in wissenschaftlichen Bibliotheken spielt in Zeiten einer zunehmenden Durchdringung des Medienangebots von Bibliotheken durch elektronische Produkte eine immer größere Rolle. Die Nutzung und Aufbewahrung von Printbeständen wird bei vorhandenen elektronischen Parallelangeboten in wissenschaftlichen Bibliotheken zunehmend hinterfragt, und alternative Möglichkeiten der Raumnutzung und der Aufbewahrung von wenig genutzten Bibliotheksbeständen werden geprüft. Dieser Trend ist nicht nur eine spezifisch deutsche Entwicklung, sondern betrifft auch andere Bibliotheken in Europa und auf der Welt: Man ist bestrebt, die Inhalte der Sammlungen für die aktuellen und zukünftigen Nutzungen zu bewahren bei gleichzeitiger höchstmöglich effektiver Ausnutzung des dafür zur Verfügung stehenden Platzes. Hierfür gibt es in Europa zahlreiche, durchaus unterschiedliche Modelle, die lokal, regional oder national konsortial und kollaborativ angelegt sind. Der Artikel gibt eine Einführung und einen Überblick über die aktuellen europäischen Initiativen und deren Strategien, die gesetzlichen Grundlagen bzw. Vertragswerke sowie die gewählten Zugangsmöglichkeiten (light, dim or dark archiving).

Mit dem Universitätsgesetz 2002 – UG wurden sämtliche österreichischen Universitäten autonome Einrichtungen in finanziellen und administrativen Angelegenheiten. Eine Auswirkung dieser Entwicklung war, dass sich die jeweiligen Universitätsbibliotheken ab sofort im direkten Verteilungskampf mit den übrigen universitären Einrichtungen befanden. Dieser Beitrag beschreibt nach einer kurzen Übersicht früherer Reaktionen auf diese Veränderung das Projekt „Gemeinsame Archivierung an österreichischen Universitätsbibliotheken“: Printexemplare elektronisch lizenzierter Zeitschriften werden österreichweit nur mehr einmal aufgehoben. Sogenannte „Beste Bestände“ werden eruiert und an zu benennenden Bibliotheken archiviert. Das System der verteilten Archivierung soll zu einer gleichmäßigen Aufteilung der Belastung führen und ohne zusätzliche zentrale Budgetmittel durchgeführt werden. Im Folgenden werden die Grundsätze des nötigen Vertragswerks, Workflows und die angestrebten Einsparungen dargestellt. Ein besonderer Schwerpunkt gilt der Implementierung einer notwendigen Kommunikationsstruktur. Zuletzt wird ein kurzer Ausblick auf die internationale Zusammenarbeit im Rahmen von EPICo geboten.

Published: July 2017

The control of thermal stability of polyaniline (PANI) nanofibers is reported by systematically varying the loadings of CaO in the range from 0.005 g to 1.0 g. It was found to gradually increase the yield of synthesized PANI nanofibers with the increase of CaO addition. The highest yield, 1.103 g was obtained for 1.00 g loading of CaO. The incorporation of CaO into PANI matrix was revealed by energy-dispersive X-ray spectroscopy (EDX). Thermogravimetric analysis (TGA) data showed that the thermal stability of PANI nanofibers was greatly improved when CaO was added to the system. 1.00 g loading of CaO is favorable to obtain comparatively more thermally stable PANI. The degradation of PANI chains started at 330 °C for the PANI-CaO composites obtained at 1.00 g CaO addition, which is the highest temperature compared to PANI and the samples synthesized at other amount of CaO loadings. Furthermore, the increasing trend of thermal stability was observed with the increasing of CaO loading.
Role of Women in Security and Defense: Bulgarian National Policies and Experience
Authors: Atanasova-Krasteva Nevena
Published: July 2017

The paper focuses on the policies for gender equality which can and should be understood as a long-term investment, not as a situational solution or a short-term cost, especially in military environment. On the basis of the UN Security Council Resolution 1325 - “Women, peace and security”, the National plan for implementation of the Resolution 1325 in the MoD in Bulgaria has been analyzed. New policies or initiatives concerning the implementation of gender in the Bulgarian Armed Forces are included with the actual information about female active duty military personnel and the perspectives to overcome the prejudices and stereotypes in people’s minds.
The Forest Offences and the National Security of Romania
Authors: Bența Anca Elena
Published: July 2017

In the last 25 years, we have assisted to an increase of the criminal actions in the forestry field. The factors generating the criminal phenomenon in the above mentioned field are social, economic, to which we can add the lack in people’s education, as well as some persons’ mentality and, last but not least, we mention poverty and the wish to get rich under any circumstances. The prevailing factor is corruption existing at all levels, some people’s eagerness of easily gained wealth and the lack of involvement of the government institutions, which were supposed to take measures in this respect. In many cases, the forestry criminal actions were undertaken with the help of certain representatives of judicial organs or public institutions and authorities of the state. Illegal cutting of trees, illegal deforestation and inappropriate forestry become a new threat to the national security of Romania. The new Forestry Code makes provisions for the illegal actions that are considered criminal offences and for the criminal sanctions for committing forestry crimes. These illegal actions have serious consequences: financial, for the environment, for the national security, requiring measures to reduce them and to fight against their negative effects.
Security and Privacy in Smart Devices Era
Authors: Bojor Laviniu
Published: July 2017

Today, more than ever, our society has become obsessed with technology and people surround themselves with smart devices designed to improve their lifestyle. Communications have benefited of this rise of the gadgets the most, and reality shows that most adults in the urban environment own a smartphone with the help of which they can connect to the Internet. We would be tempted to state that the World Wide Web will change in the future into Human World Wide Web, but connecting to the Internet does not stop here. Vehicles, TV sets and other electronic devices or appliances have already started to be connected to the Internet, which makes it easier to believe that, in the future, we will live in a society where most devices around us will be interconnected to a global or even spatial network. This concept, which the academic world embraced as the Internet of Things, should be understood and accepted by society not only from the perspective of the deprivation of privacy it generates, but especially from the perspective of the insecurity, a possible result of this dependence on software and programs that can be remotely accessed and controlled.
Keystones of Irregular Warfare
Authors: Hrnčiar Michal
Published: July 2017

The current security environment is evolving towards a global complexity of unpredictable events. The risk of state and non-state actors attempting to achieve their goals through destabilization exists. In the operating environment, this implies a blurring of the boundaries between state and nonstate actors (such as insurgents, terrorists and criminals) and NATO may confront an adversary who uses traditional (conventional), irregular warfare or both (hybrid warfare). The aim of the article is to find, analyze and describe the key elements that fundamentally different irregular of traditional (conventional) and hybrid warfare.
Cyberwarfare
Authors: Hruza Petr , Cerny Jiri
Published: July 2017

The internet has to be considered a very dangerous battlefield. Nobody is secure. It is a paradox that those countries which do not feel vulnerable may be the most threatened by cyber war. This applies primarily to western powers and fast developing countries. Cyberattack may easily be ordered through the internet. Such an attack is cheaper than an attack by conventional weapons and at the same time it causes bigger economic losses. It is obvious from the military standpoint that cyberattacks and defence against them have to be an indispensable part of military activities. The reason is that the military consider the internet and virtual space to be the fifth area of employment of their forces, besides land, air, water and space. It is stated in the hypotheses that cyber activities will be an inseparable part of future military operations. The key objective will be to achieve information supremacy or information dominance on the battlefield. Thus developed countries develop and introduce new cyber weapons with the aim of striking the enemy´s command and control structures, its logistics, transport, early warning systems and other vitally important military functions at any time upon receiving an order.

The paper summarizes the research results of commanders’ managerial competences. The aim of the research consisted in identifying facts, which managerial competences make or do not make troubles for commanders; there are offered recommendations for the development of commanders’ critical competences. The research was conducted within three groups of respondents: the first group comprised senior officers, participants of the General Staff course; the second group comprised junior officers, participants of the senior officer course, and the third group covered graduates of the basic officers’ course. Using the questionnaire research, respondents rated ten selected managerial competences of their subordinates. The research results concluded that commanders face the greatest difficulties in communication, self-development and analytical thinking.
Civil Preparation of the Battlespace - Necessity in the Irregular or Hybrid Warfare
Authors: Rațiu Aurelian
Published: July 2017

The lessons learned from the most recent conflicts or theatres of operations in Iraq, Afghanistan, Ukraine, or Syria prove that the Intelligence Preparation of the Battlefield (IPB) process is no longer sufficient. Why? Because in the irregular and hybrid conflicts the centre of gravity is represented by the civilian population, which requires precise understanding of the operational environment, including aspects about the local communities, and profound knowledge of the people, their social structures, their culture, their customs, and their way of thinking and reacting to certain internal and external stimuli. In such an operational environment, protecting the civilian population becomes the main mission of the armed forces. Consequently, we present the most important stages through which the Civil Preparation of the Battlespace (CPB) can be accomplished.
The Vicious Circle of Subsidised Employment
Authors: Varbanova Boryana
Published: July 2017

The problem with subsidised employment has become more and more serious in recent years. There is a trend in which vulnerable groups lose their jobs again after the period of support. Our focus in this report is on employment and, in particular, on the issues related to its effective and not so effective stimulation. When implementing this strategy in Bulgaria, institutions aim primarily at reaching certain numeric indicators, rather than structural reforms and discontinuation of bad practices.
New Approach – Quadrangle of Knowledge Based Sustainability
Authors: Nicolescu Ovidiu , Nicolescu Ciprian
Published: July 2017

In our paper we start the analysis of the performance in the knowledge based economy from two premises: a. The productivity of the new economy is much higher comparative with the previous economic systems; b. There are at least six factors which determine the deep change of knowledge business organisation performances. Based on this approach we mention several specific ways for the evaluation of the knowledge based performances formulated by certain renowned international specialists. Finally, we elaborate a new concept regarding the approach and evaluation of the performance in the knowledge based economy - quadrangle of sustainability based on knowledge.
