GROUNDWATER GEOCHEMISTRY OF RROGOZHINA AQUIFER (WESTERN ALBANIA)
Authors: Luzati S. , Beqiraj A. , Jaupaj O.
Published: July 2017

This paper aims to make a geochemical characterization of the groundwater of Rrogozhina aquifer which extends over the Albanian pre-Adriatic depression covering a surface of 2100 km2. It is a multilayered aquifer consisting of intercalations between water-bearing Pliocene sandstone and conglomerate with impermeable clay layers. This aquifer occurs under typically artesian conditions because of its impermeable clay basement and semi-impermeable Quaternary cover. The groundwater shows variable geochemical composition due to different mineralogical composition of its medium and vast extension of the aquifer. However, the mainly magmatic - carbonatic mineralogical composition of the water - bearing sandstones and conglomerates has determined a geochemical composition of groundwater consisting mostly of HCO3-Mg-Ca hydrochemical groundwater type. Dissolution of minerals seems to be the major geochemical processes in the formation of the groundwater composition. The above mainly magmatic composition of sandstones and conglomerates is also responsable for the high content of iron in the grounwater of this aquifer. Iron content is higher in sandstone related groundwater where the silt fraction is mainly composed by ironbearing minerals such as magnetite, epidote, granate, sphene, amphibole and pyroxene. The general mineralization and general hardness of groundwater range from 500 to 800 mg/l and from 11 to 25ºdH, respectively.
LANDSLIDE GEOHAZARD FOR PIPELINES OF NATURAL GAS TRANSPORT
Authors: Marinos V. , Stoumpos G. , Papathanassiou G. , Grendas N. , Papouli D. , Papazachos C.
Published: July 2017

Landslides represent a significant hazard for pipelines because they can generate permanent ground displacement and tend to result in complete failure or significant leaks, major environmental impacts and long periods of service disruption. Hence, landslide-related incidents are regarded as a significant operational risk. The paper mainly focuses on the assessment of landslide hazard along or across a natural gas pipeline project and on the identification of these hazards, mostly in the field. Whether the “expected” landslide event reaches the Right of Way (RoW) and impacts the pipeline, is influenced by the nature and size of the expected landslide event, controlled by the site geology and geomorphology, the proximity of the existing landslide feature to the pipeline and the position of the pipeline relative to the landslide. Landslide hazard assessment is used to identify “hot spots” along the pipeline route where re-routing or risk reduction measures must be prioritised. When landslides that can threat the pipeline integrity cannot be avoided, more detailed site evaluation is required to support the design and construction of mitigation measures.
ASSESSING THE SUITABILITY OF GROUNDWATER FOR DRINKING AND AGRICULTURAL USES IN THE ZACHARO BASIN, SW PELOPONNESUS
Authors: Panagopoulos G. , Lambrakis N. , Chalvantzis C. , Bekiari V. , Avramidis P.
Published: July 2017

The hydrochemical character of the Zacharo basin groundwaters and their suitability for drinking and irrigation purposes are evaluated in this paper. The Pindos karst aquifer, the Neogene and the alluvial aquifer are the three most mportant aquifers of the study area. 46 water samples were taken from wells, boreholes and spring and they analyzed for the physicochemical parameters (pH, EC and TOC), major ions (Ca2+, Mg2+, Na+, K+, NH4+, HCO3-, Cl-, F-, SO4 2- and NO3-) and trace metals (B, Fe, Mn, Cr, Pb, Se, Ni). The suitability of groundwaters for drinking and irrigation is evaluated by the calculation of Water Quality Index and the indices SAR, %Na, RSC and KR. The water of the karstic and alluvial aquifer is of “excellent” quality for both uses. On the other hand, the Neogene aquifer shows serious problems in respect with the degradation of water quality, since 20% of the samples are of “poor” and “extremely poor” quality for drinking purposes and 33% are “unsuitable” for irrigation. The degradation of water quality is attributed to natural processes of enhanced ion exchange, since the cation exchange capacity of the aquifer materials is increased due to the presence of clay minerals and organic matter.
COASTAL CLIFF INSTABILITY, A CASE STUDY FROM THE UK
Authors: Saroglou C. , Alexandrou D.
Published: July 2017

The present paper presents the conceptual ground model for coastal cliff retreat and instability. Cliff instability has been intensified due to climate change in the last years, especially by sea level change and high windstorms. A case study ofcliff instability in the SW coast in the UK is presented. The stability of the cliffs is primarily controlled by the presence of tensile cracks parallel to the cliff face and intersecting fractures as well as undercutting of cliff base due to wave action. The cliff instability mechanisms were identified for different locations along the shoreline and the cliffs were classified according to the cliff behaviour unit approach.
GRANULAR AQUIFER SYSTEM OF WEST CHALKIDIKI AREA, REGION OF CENTRAL MACEDONIA, NORTHERN GREECE
Authors: Veranis N. , Nimfopoulos M. , Christidis C. , Chrysafi A.
Published: July 2017

The granular aquifer system of the western Chalkidiki peninsula covers an area of 667 Km2 occupying Neogene and Quaternary sediments. The present study deals with the hydrogeological and hydrogeochemical characterization of the granular aquifer system for the purposes of efficient utilization and management of groundwater resources. It is a multilayered formation, composed of unconsolidated to semi-consolidated sands, gravels, conglomerates, sandstones and marly limestones with intercalated impermeable to semi-permeable beds of clays, marls or mixed with pebbles and sands. The aquifer system is characterized by medium to moderate hydrocapacity and the pumped groundwater consumptions are 74*106 m3/yr. Piezometric studies carried out in the period of 2003-14, conclude that the piezometric surface decline is located in the S and SE parts of the aquifer system, while in the rest Central and NW parts there is a noticeable rising of the groundwater table. Groundwater is generally characterized by a good quality; however, groundwaters of the broader Triglia area, have excessively high contents of As (10 to 3400 μgr/l) and B (1.5 to 4.0 mg/l). Other natural pollutants are Fe and Mn. Salinization and high values of nitrate are mainly detected in water boreholes of Moudania-Portaria, Akrotiri-Epanomi and Agelochori areas.

Published: July 2017

The aim of this study is to evaluate climate model hydrological parameters in comparison to recorded hydrological data and estimate the impacts of climate change on water balance. For this purpose, a combination of climate model precipitation and temperature data and Thornthwaite method was applied for the period 1988-2000 and the future periods 2028-2040, 2058-2070 and 2088 2100. The application of this combination was carried out in a coastal region in Southeastern part of Korinthiakos Gulf (southern Greece). The area is suitable for this target, because it is characterized by urbanization, intensive agriculture and tourism development, with increasing water demands. The evaluation of climate model parameters in comparison to observed data shows that the RegCM3 model is a reliable model. According to the future projections and the Thornthwaite method, the real evapotranspiration is estimated to increase, as a result precipitation decrease and temperature increase.
THE CRUSTAL ANISOTROPY PATTERN IN THE EPICENTRAL AREA OF THE 2008 MW 6.4 EARTHQUAKE IN NORTHWEST PELOPONNESE, GREECE

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.

Authors: Norda M.E. , Prapiga A. , Paraskevopoulos P. , Tselentis G.A
Published: July 2017

Horizontal to Vertical Spectral Ratio (HVSR) method has been applied on ambient noise records at the Rio- Antirio area (central Greece). The dataset used was recorded during 7 days by 12 temporary seismic stations deployed in the area. The stations were laid out along a profile and their interval was approximately 500m. The main part of the processing was done using Geopsy software. The aim of this study was to estimate the fundamental frequency at the station sites and its variation with time and azimuth. The processing results showed that for most stations along the profile, the peaks of the HVSR curve are not strong enough and often there are, more than one, peaks, which seem to be persistent during the whole recording time. When taking the azimuth into account, some of the stations show dominant and persistent directions were the HVSR ratio is stronger, while it has been observed that this direction could vary for different frequency peaks of the same stations. Finally, the top sediment layer’s geometry and thickness were estimated using Vs velocity results from nearby crosshole measurements.
MATERIAL AND STRESS ROTATIONS: THE KEY TO RECONCILING CRUSTAL FAULTING COMPLEXITY WITH ROCK MECHANICS
Authors: Nur A.
Published: July 2017

The most common test of breaking rocks in the laboratory under compression has provided the basis for most of the widely used modeling of faulting and the earthquake instability in the earth’s crust. But it has not been able to explain the actual complexity of fault systems insitu. However a greatly generalized lab experiment - widely overlooked for decades - provides the missing links needed to begin to understand the actual complexity of fault systems insitu.
STATISTICS OF EARTHQUAKE RECURRENCE TIME IN NORTH AEGEAN TROUGH

Published: July 2017

The determination of recurrence time of strong earthquakes of certain magnitude on a specific fault or fault segment is an important component of seismic hazard assessment. The occurrence of these earthquakes is neither periodic nor completely random but often clustered in time. This fact in connection with their limited number inhibits a deterministic approach for recurrence times calculation and thus application of stochastic processes is required. For recurrence times determination in the area of North Aegean, all the available information on strong earthquakes (historical and instrumental) with M6.0 is collected. Given that source parameters of historical events contain larger uncertainties, reassessment of their focal parameters before the application of stochastic processes is necessary, which was performed by applying the method of Bakun and Wentworth (1997). The reasses sed catalogue was divided into three data sets, according to the strong events spatial distribution and their association with distinctive fault segments. Three statistical distributions (Weibull, inverse Gaussian, lognormal) were applied and evaluated with the Anderson–Darling test and the Akaike and Bayesian Information Criteria. The Weibull distribution exhibited better performance in two out of three data sets and the Inverse Gaussian distribution in the third. With given distributions the occurrence probabilities were calculated for strong events above a certain magnitude and for certain time interval.
SEISMIC HAZARD ASSESSMENT FOR THE CORINTH GULF AND CENTRAL IONIAN ISLANDS BY MEANS OF THE LINKED STRESS RELEASE MODEL
Authors: Mangira O. , Papadimitriou E. , Tsaklidis G. , Vasiliadis G.
Published: July 2017

Εarthquake generation causes spatio-temporal stress changes on adjacent fault segments that can alter the occurrence probability of subsequent earthquakes onto them. The interaction is investigated with the Linked Stress Release Model, applied to fit historical data from two areas that accommodate high seismicity, the Corinth Gulf and the Central Ionian Islands. These two areas are divided in two subareas, based on seismotectonic features; Corinth Gulf is divided in the western and eastern part, whereas the area of Central Ionian Islands is divided in Kefalonia and Lefkada subareas. The results establish interactions between the subareas, especially in the Central Ionian Islands, and underline the differences in tectonic structures and earthquake mechanisms between these areas. Particularly, the seismicity in the Central Ionian Islands is proved to be more complex and active and yet more difficult to be examined, whereas the LSRM fits the Corinth Gulf data more easily.
MODELING THE SEISMICITY OF CENTRAL IONIAN ISLANDS WITH SEMI-MARKOV MODELS
Authors: Pertsinidou C.E. , Tsaklidis G. , Limnios N. , Papadimitriou E.
Published: July 2017

Earthquakes with M ≥ 5.2 that occurred in the area of central Ionian Islands (1911- 2014) are assumed to form a semi-Markov chain, aiming to contribute in the field of seismic hazard assessment. The sojourn times are considered to be geometric or approximated by Pareto distributions. Destination probabilities are examined and the results demonstrate that in many cases these probabilities become higher adequately forecasting the magnitude class of an anticipated earthquake. The geometrically distributed model can also reveal the more probable occurrence time of the next earthquake since for this model the destination probabilities were found to obtain many times their maximum values for the real occurrence time. The successful forecasting as for the occurrence time is 63.75% for all earthquakes and becomes 71.42% for the larger magnitude events (M ≥ 6.0).

Published: July 2017

Based on the results of our studies for the tidal triggering effect on the seismicity of the Hellenic area, we consider the confidence level of earthquake occurrence - tidal period accordance p as an index of tectonic stress criticality for earthquake occurrence. In this paper, by the occasion of the recent catastrophic earthquake of Nepal, we investigate the variation of the index p for the South Himalaia Fault area. The preliminary results indicate positive correlation of the index p with seismicity, for all the tidal periods. We suggest that this compliance parameter p may be used as an additional element for the seismic risk assessment.

Published: July 2017

This paper is focused on the study of the North Aegean seabed, from a Digital Seabed Elevation Model (DSEM), by employing Object Based Image Analysis (OBIA). The goal is the automatic extraction of geomorphological features based on morphological criteria, in the North Aegean Basin. A Digital Seabed Elevation Model (DSEM) of 150x150 meters resolution was employed. At first, slope gradient, profile curvature, and percentile were derived from this DSEM. Four different layers of segmentation were created in order to extract the final geomorphological classes, discontinuities, faults like and fault surface in the final segmentation of level 4. On previous levels, more geomorphological features were also classified such as continental platform and continental slope. The results were evaluated qualitatively and quantitatively, through a tectonic map which has been created manually based on the analysis of seismic profiles. The results of the comparison of the two methods were satisfactory. Thus, the developed OBIA method is considered successful.

This paper is focused on the study of the South Cretan Margin, from a Digital Seabed Elevation Model, by employing Object Based Image Analysis. The goal is the automatic extraction of geomorphological and morphotectonic features based on morphological criteria and topological relations. A Digital Seabed Elevation Model of 150x150 meters resolution was employed. At first, slope, curvature, planform curvature, profile curvature and Topographic Position Index were derived from this DSEM. Five different layers of segmentation were created in order to extract the final geomorphological classes, Ptolemy trough, intraslope basins, main basins, small basins, continental shelf, plains, continental slope, escarpments, canyons, spurs, discontinuities, fault like and fault surface. The results were evaluated quantitatively, through the established indices Completeness, Correctness and Overall Quality. For computing these indices, it was necessary to digitize the boundaries of the objects derived by photo-interpretation. Then, the computation of the above indices, took place by comparing the results of digitized photo-interpretation boundaries, to the extracted feature boundaries through OBIA analysis (in shapefile). It is worth noting that, the results of the evaluation are quite satisfactory. Thus, the developed OBIA method is considered successful.

Authors: Tsangaratos P. , Ilia I.
Published: July 2017

The main objective of the present study was to develop a landslide susceptibility model by combining Fuzzy logic and Information Theory in order to estimate the spatial probability of landslide manifestation, in the mountains of central Tzoumerka, Greece. Specifically, Fuzzy logic was enabled for weighting the landslide related variables based on expert knowledge and in respect to landslide susceptibility, while the Shannon’s entropy index, an index from Information Theory, was calculated to weight the significance of each landslide related variable based on the available data. The final landslide susceptibility map was produced by applying the weighted sum method. Engineering lithological units, slope angle, slope aspect, distance from tectonic features, distance from river network and distance from road network were among the six landslide related variables that were included in the landslide database used in the training phase. The landslide inventory map was constructed by interpreting aerial photographs, satellite images and field surveys and was separated into two datasets, one for training and one for validating the model. The outcomes of the validation process illustrated that the developed methodology efficiently provided the most susceptible areas and was in good agreement with the actual landslide locations. The area under the curve was estimated to be for the training and validating datasets 0.7575 and 0.7828 respectively. The produced landslide susceptibility map could be regarded from local and national authorities as a valuable mean to evaluate strategies or to prevent and mitigate the impact of landslides. Keywords: slope stability, fuzzy weighting, Shannon’s entropy index, Tzoumerka, Greece.

The article is devoted to considering of the level of burnout and meaning of life orientation of teachers. In the course of empirical research, it is shown that respondents with a strong level of emotional burnout was statistically more frequently observed mismatch in the semantic system of life orientations than respondents with mild burnout. For the last inner harmony, acceptance of his past, present and future is typical. The paper also outlines a paradox: a stressful situation, provoking emotional burnout, may under certain circumstances be considered as conditions for the development of teachers and psychologists. To identify these conditions and to develop on their basis a more modern medico-hygienic norms of work of teachers and psychologists, the authors see prospects for implementation of structural methods of protection from burnout.

Authors: Peixoto Nei
Published: July 2017

O feijão azuki is é uma espécie apreciada na Ásia, principalmente na China e no Japão. No Brasil é utilizado principalmente por descendentes de imigrantes desses países e por consumidores de alimentos naturais. Apresenta elevado potencial de cultivo por agricultores familiares como opção de diversificação de culturas e geração de renda. Com o objetivo verificar a resposta de feijão azuki à adubação mineral com NPK, foi conduzido um experimento de campo em Latossolo Vermelho-Amarelo localizado na Universidade Estadual de Goiás, Câmpus Ipameri. Utilizou-se o delineamento de bloco ao acaso com seis doses do formulado N-P-K 5-25-15 (100, 200, 300, 400, 500 e 600 kg ha-1) e quatro repetições. As plantas produziram, em média, 5,7 sementes por vagem, não havendo diferença significativa entre doses. Para massa de 100 grãos a média de 9,03 g, também sem diferenças significativas. Efeitos lineares positivos com o incremento das doses foram obtidos para altura de planta, número de vagens por planta e produtividade de grãos.

Aplicações sucessivas de dejetos e em altas doses no solo podem resultar em impactos ambientais indesejáveis, como desbalanço nutricional pelo acúmulo de nutrientes e consequentemente poluição de águas subterrâneas, trazendo riscos de contaminação do lençol freático. O objetivo desse trabalho foi determinar as quantidades de água percolada diariamente e os teores de amônio e nitrato lixiviados, durante o cultivo da soja, com base nas precipitações e adubações (adubação mineral, 25 e 100 m3 ha-1 de dejetos líquidos de suínos), afim de fornecer resultados que aperfeiçoem o manejo de dejetos líquidos de suínos, de forma satisfatória, reduzindo custos e evitando possíveis impactos ambientais. A precipitação total ocorrida na área experimental na safra 2015/2016 foi de 1.253,5 mm. O padrão de percolação da água no perfil do solo foi semelhante independente das adubações, não havendo diferença entre as perdas totais de água por percolação, em relação às adubações aplicadas. Os teores de amônio na água são baixos em relação a quantidade aplicada de nitrogênio e os teores médios de nitrato na água percolada estão nos níveis aceitáveis de potabilidade da água, independentemente da adubação recebida.

A propagação das sementes de Ochroma pyramidale é limitada, pois, possui dormência tegumentar e baixa taxa de germinação natural. Uma alternativa viável para essas limitações, é a micropropagação. Essa técnica visa produzir mudas em larga escala, com qualidade superior, em curto período e espaço reduzido. Dessa forma, o trabalho teve como objetivo avaliar o efeito de diferentes concentrações de sais no meio MS e de sacarose, no estabelecimento in vitro de sementes de pau-de-balsa. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema fatorial 2x4, duas concentrações de meio MS (50 e 100%) e quatro de sacarose (0, 15, 20 e 25 g L-1), totalizando 8 tratamentos com 15 repetições e em cada repetição 3 indivíduos, totalizando, 360 indivíduos. Observou-se a influência da concentração do meio MS e sacarose no estabelecimento in vitro da espécie, uma vez que, as variáveis germinação, número de par de folhas, comprimento radicular e da parte aérea, massa seca e fresca, além dos menores valores de calogênese, plantas senescentes, e contaminação, foram obtidos, quando submetidas a baixa disponibilidade de sais minerais e sacarose. Os melhores tratamentos, foram os que continham 50% de sais no meio MS com 15 e 20 g L-1 de sacarose.

A construção de barragens em regiões de vale provoca o aumento na disponibilidade hídrica do solo, afetando o estabelecimento e a sobrevivência das espécies de plantas especialistas de solos com baixa umidade. Foram pesquisados artigos científicos, documentos técnicos e livros sobre o tema “impactos ambientais causados por usinas hidrelétricas e represamentos” existentes em bases indexadoras e órgãos públicos com objetivo de evidenciar os principais impactos causados por barragens acima da cota de inundação para florestas que antes se situavam distantes de recursos hídricos e passam a se situar próximas das águas do lago artificial criado. Dentre os principais impactos listados pelos estudos estão: a fragmentação de habitats, dificultando ou às vezes impossibilitando o fluxo gênico entre esses fragmentos (14 estudos), alterações na estrutura, biomassa e fluxo de carbono (28) e modificações da fitofisionomia das florestas (05 estudos), sobretudo quanto à dispersão de sementes. Apesar desses impactos já serem conhecidos, há poucos estudos que monitoram as mudanças das funções desempenhadas por essas florestas á longo prazo.

A composição química da planta é uma característica importante para o melhoramento genético, pois pode variar com o genótipo. Dessa forma, o objetivo desse estudo foi avaliar seis populações de J. curcas quanto aos teores de macro e micronutrientes nas folhas e frutos. O experimento foi conduzido no Campo Diogo Alves de Mello, pertencente à Universidade Federal de Viçosa, Minas Gerais, Brasil. Utilizou-se o delineamento em blocos casualizados, os tratamentos constituídos por seis populações de J. curcas, oriundas dos municípios mineiros de Janaúba (J1, J2, J3, J4 e J5) e Bonfim (B1). Determinaram os teores de N, P, K, Ca, Mg, S, Zn, Fe, Mn e Cu nas folhas e frutos das diferentes populações em várias épocas durante o ciclo da cultura. Para os teores foliares verificou-se efeito significativo apenas para o zinco, sendo a B1 aquela que apresentou o menor conteúdo. Em relação aos frutos, a população B1 apresentou os menores teores de P e Cu, enquanto que as populações J1 e J5 apresentou o maior teor de ferro.
La invención de la política en el siglo XII: reflexiones y propuestas desde una perspectiva conceptual
Authors: Carrasco Manchado Ana Isabel
Published: July 2017

Este trabajo tiene un doble objetivo. El primero, subrayar la conveniencia de adoptar la perspectiva conceptual de Reinhart Koselleck, y otras propuestas vinculadas a la semántica histórica, para estudiar las realidades políticas medievales. Tópicos historiográficos, como el de cultura política, pueden ser mejor entendidos guiándose por la perspectiva conceptual y sometiendo a crítica la propia noción de ‘política’, despojándola de los significados actuales. El segundo objetivo pretende la aproximación al concepto de ‘política’ en el siglo XII, a través de un recorrido por la adopción e impulso de la palabra ‘política’ en la cultura medieval y su uso por autores como Juan de Salisbury. Apoyaremos la tesis de la politización del poder en el siglo XII y de la formación de una cultura política paralela. Es el punto de partida para una mejor comprensión de los cambios institucionales en las relaciones de poder que se producirán durante los siglos XIII al XV.
Diplomacy in the Fifteenth-Century Monarchical State: A Baronial Pursuit? (Portugal, 1416-1449)
Authors: Viúla de Faria Tiago
Published: July 2017

In 1438 Pedro, Duke of Coimbra, was second-in-line to the Portuguese throne. The death of his elder brother Duarte had left the royal seat vacant and Pedro, a middle-aged, powerful magnate was elected as regent for Duarte’s son Afonso, the boy of six to whom the crown fell. First as the coregent and then single-handedly, Pedro governed over Portugal and its elites during a decade marked in turn by contentment and upheaval, as much as by courtly struggles between aristocratic factions. In 1449, amidst accusations of lese-majesty and of favouring his own, Pedro would meet a bitter end in the field of battle, at the hands of his young nephew, King Afonso V, seemingly manipulated by an influential clique of enemies to the regent. This paper will examine Pedro of Coimbra and some of the men surrounding him during his political career (c. 1416 to 1449), in particular those employed as «diplomats» in foreign service. It will trace three different stages in Pedro’s trajectory — as a prince in the making, as the king’s counsellor, and finally as regent of the Portuguese kingdom — in order to question the extent to which a leading magnate of the fifteenth century was able to project his political influence in tandem with, or in reaction to, royal power. Ultimately, the paper highlights the co-existence, and indeed the overlap, between royal and non-royal diplomatic ambitions and the strains and challenges that it caused in the politics and diplomacy of Portugal in this period.
Radicalism, Counter-Radicalism and the American Legion, 1919–1940
Authors: Lewis George
Published: July 2017

The means by which the United States sought to identify radicals and radicalism in the inter-war years has been largely hidden by a scholarship that has, instead, chosen to focus on processes of Americanization. By analysing hitherto hidden and underused archival sources, this essay examines the ways in which the American Legion positioned itself to become the single most important lobbying force in the identification of inter-war radicalism in the USA, used its considerable resources to sustain a vigorous programme to identify radicalism which served its own organizational interests, and, therefore, had a significant and meaningful impact on debates over radicalism and Americanism at local, state and national levels. The Legion reacted to a changing climate which saw radicalism identified first as an external, immigrant-led threat in the early 1920s, and then as an internal, home-grown menace as the 1930s drew on. That saw the organization grapple with questions including the innate intelligence of immigrants, as debates raged over whether radicals were lured unwittingly into that radicalism or chose radicalism because of a fiendish acumen. Throughout the period, the Legion’s view of radicalism was deeply subjective, but was disseminated – and all too regularly accepted – with a polished veneer of objectivity that belied the often vituperative national debates that surrounded ideas of radicalism.
Unreadability is the Reader’s Problem:
The Book of Mormon’s Critique of the Antebellum US Public Sphere
Authors: Sudholt Jonathan
Published: July 2017

This article reads
The Book of Mormon as an attack on the incoherence of American nationalism – as, specifically, a book about the inevitability of its own irrelevance. That is, its primary objection is that in order for Joseph Smith to get any attention at all within the unruly public sphere of Jacksonian America, he had to write a book that would get him the wrong kind of attention – attention as a religious fanatic rather than as a critic of the culture that creates religious fanatics. Joseph Smith believed there was something rotten at the heart of America, but, being an uneducated farm boy from western New York, he had no way to express his anger in a manner that would allow him to be taken seriously. He could only be an ‘authority’ with regard to religion, and religious authority, being ubiquitous, was no authority at all. Smith tracks the way the American public sphere forced its marginalized persons to criticize it from a disadvantageous position, and the way those critiques were turned to the establishment’s advantage. For Joseph Smith, freedom of speech in America has always been a tool of the political elites to keep the poor from speaking effectively.
Nonlinear Effects of Social Connections and Interactions on Individual Goal Attainment and Spending: Evidences from Online Gaming Markets
Authors: Zhang Cheng , Phang Chee Wei , Wu Qingsheng , Luo Xueming
Published: July 2017

Although it seems intuitive for firms to leverage social connections and interactions to influence consumers’ goal attainment and spending, the authors present a caveat of such strategies. Using two large-scale data sets with more than 5 million people-day observations from online gaming markets, Studies 1 and 2 show consistently nonlinear effects. Although some social connections and interactions boost goal attainment and spending (positive linear term), after a certain point too many of them have a diminished marginal effect (negative squared term). The results are robust to a wide array of modeling techniques addressing self-selection, unobserved individual heterogeneity, and endogeneity. In addition, novices can benefit more from greater social connections and interactions, yet also suffer more from the diminishing effects. Regarding the underlying mechanism, the follow-up experiment Study 3 shows that consistent with the information processing theory, some social connections and interactions can provide information support for goal attainment, but too many of them can introduce an information overload problem and, thus, hamper goal attainment intention. Together, these findings refute a simple, linear view of the effects of social connections and interactions and provide pivotal theoretical and practical implications.

Published: July 2017

Background

The aim of the study was to evaluate the antibacterial effect of a drug releasing poly (3-hydroxybutyrate) (P(3HB)) implant coating in comparison to pure titanium on

Methods

Titanium discs were coated with P(3HB) containing 5% (w) and 10% (w) of metronidazole, either with and without a P(3HB) topcoat. The biofilm formation was evaluated after 1, 4 and 9 days in a dynamic flow chamber system. Microbial adherence was quantified by determination of bacterial surface coverage.

Results

The evaluated formulations of P(3HB)/metronidazole showed an antibacterial effect especially in the first 24 h. Prolonged incubation for 9 days showed reduced bacterial adhesion only on polymer coatings loaded with 10% (w) of metronidazole both with and without topcoat.

Conclusions

The evaluated coating formulations can provide protection from an
Punches or punchlines? Honor, face, and dignity cultures encourage different reactions to provocation

Published: July 2017

Research on culture-related violence has typically focused on honor cultures and their justification of certain forms of aggression as reactions to provocation. In contrast, amusement and humor as the preferred reactions to provocation remain understudied phenomena, especially in a cross-cultural context. In an attempt to remedy this, participants from an honor culture (Poland), dignity culture (Canada), and face culture (China) were asked how they would react and how they would like to react to a series of provocative scenarios. Results confirmed that aggression may be the preferred reaction to provocation in honor cultures, while the preferred reaction to provocation in dignity cultures may be based on humor and amusement. The third kind of provocation reaction, withdrawal, turned out to be more complex but was most popular in dignity and face cultures. Furthermore, results confirmed that the way individuals think they would behave is more culturally diversified than the way individuals would like to behave.

Authors: Baboș Alexandru , Baboș Alina-Mihaela
Published: July 2017

The transport problem finds its application in situations where the upper echelons must draw up an optimal plan of resources allocation for combat capabilities on objectives. In order to achieve more reliable results for the real problem, the data needed to formulate the mathematical model are extracted from an order of operations. This paper presents the optimization of military action, showing how to solve a practical problem using the transportation problem.
Military Education and Training Supported by Blended Simulation
Authors: Bučka Pavel , Andrassy Vladimír
Published: July 2017

The existing conflicts, both military and non-military are currently mostly of non-linear nature, where units composed of multiple specializations, both smaller and acting independently are prevailing. Those units are usually separated from home base and proper access to its own central supply lines of communication which strengthens emphasizes on their independent command and control, coordination within deployed forces and other assets within given operation. Therefore, prior collective training and preparation for deployment is one of the crucial operational planning requirements before deployment takes place. Modern training simulation techniques and assets do support preparedness of those units planned for deployment by aligning and synchronizing interoperability of their activities. One of such techniques - Blended simulation - can realistically generate a wide range of situations with exact imitation of activities to practice the ability of different types of units to the declared capabilities across the broad spectrum of tasks. Evaluation of the blended simulation effectiveness does further help to deliver more efficient methodologies and tactical procedures for further use within preparation stag. Such approach is in line with the trend of increased use of modelling and simulation techniques within military education and training.
