Published: December 2017

At present, the heads of organizations have come to realize that leading positions of their companies are allowed to them not only by use of high technologies, but also the personnel that is the basis of any organization. Just how much the organization's personnel is interested in accomplishing the tasks set, with what enthusiasm it starts to work and how externally it shows its attitude to the company is a manifestation of the involvement of employees. The problem of staff involvement is relevant both in research and in practical terms. Firstly, this is due to the current market development situation: many foreign and Russian companies have become aware of the importance of involving personnel and have begun to treat with particular interest the notion of involvement and factors of its formation. Secondly, this is due to the need to develop a theoretical framework for understanding the phenomenon of involvement, developing approaches, and developing methods to increase the level of involvement of employees in the organization. The purpose of this article is to study the theoretical aspects of the study of staff involvement and develop recommendations for improving the toolkit to increase the involvement of staff in the organization activities. The theoretical significance of the presented article is that the presented conclusions and conclusions formulated as a result of conducted research can find application in scientific work, studies, and scientific dissertations. The practical importance of this article consists in the possibility of using the developed recommendations on improving the toolkit to increase the involvement of personnel in the organization's activities in practice of functioning of commercial organizations with similar characteristics of personnel.

Published: December 2017

The article reveals the reasons for quantitative and qualitative deformation of the process of reproduction of la-bor resources in the regions of central Russia on the example of Tambov region. Attention is focused on the scale and dynamics of this deformation, which is the main difference from previously existing depopulation processes. Based on the analysis of consequences of structural changes, a whole range of regional problems is identified, including: labor depopulation, "narrowed" reproduction, labor shortages, spatial disproportion, "aging", "replacing" migration, "brain drain", de-qualification, low level and quality of life, deformed industry structure of the economy, undeveloped infrastructure. In this context, security threats for a regional economic system are identified, oriented almost exclusively for a short period. Conclusion is made about the need for rapid development of the state anti-crisis policy in this area, based on integrated approach and including measures to improve: market mechanism of functioning, main generator of which should be an "innovative drive", infrastructure, relations in the sphere of social reproduction and in the market labor, quality of life of population, level of social security, etc.

The Many Gifts of Status: How Attending to Audience Reactions Drives the Use of Status
Authors: Sharkey Amanda J. , Kovács Balázs
Published: December 2017

The majority of extant studies involving status argue that status enters into choice and evaluation because people personally believe that status serves as a signal of quality. However, this mechanism seems less plausible in cases when consensus on the meaning of quality is lacking. To understand how and why status often nonetheless enters into evaluation in those cases, this paper contributes to a growing body of work that proposes that individuals and organizations are particularly likely to base their choices and evaluations on status when they are concerned with the reactions of others. We provide an empirical test of this argument by analyzing how the sales gap between prizewinning books and their shortlisted-only peers (as well as a second similar-content control group) changes during the December holidays, when the purchase of books as gifts increases relative to purchases for one’s own personal use. Results show that the sales gap widens with the increased orientation toward gift giving, consistent with our theoretical arguments about how attending to audience reactions drives the use of status. Analyses of two online experiments allow for further clarification of the mechanism behind our findings.

Approximation Algorithms for Capacitated Perishable Inventory Systems with Positive Lead Times
Authors: Chao Xiuli , Gong Xiting , Shi Cong , Yang Chaolin , Zhang Huanan , Zhou Sean X.
Published: December 2017

Managing perishable inventory systems with positive lead times and finite ordering capacities is important but notoriously difficult in both theory and computation. The optimal control policy is extremely complicated, and no effective heuristic policy has been proposed in the literature. In this paper, we develop an easy-to-compute approximation algorithm for this class of problems and prove that it admits a theoretical worst-case performance guarantee under independent and many commonly used positively correlated demand processes. Our worst-case analysis departs significantly from those in the previous studies, requiring several novel ideas. In particular, we introduce a transient unit-matching rule to dynamically match the supply and demand units, and the notion of associated demand processes that provides the right future demand information to establish the desired results. Our numerical study demonstrates the effectiveness of the proposed algorithm.

Looking for blind spots in somatics’ evolving pathways
Authors: Fortin Sylvie
Published: December 2017

The field of somatics has expanded tremendously since Hanna introduced the term in the 1970’s. This reflective paper has evolved from my experience as a practitioner and theorist of somatics over the last 30 years. As such I will address the broadness of the field of somatics by looking at five pathways undertaken by somatic practitioners: social, ecological, spiritual, health and well-being and education. Possibilities and constraints within each of these pathways are critically examined, from an intimate, embodied and socio-political perspective, in order to bring awareness to possible blind spots associated with each pathway. In doing so, I attempt to counter overzealous stances towards somatics while at the same time recognizing and valuing its tremendous potential to generate individual and collective agency.
Syntactic complexity and language contact: A corpus-based study of relative clauses in British English and Indian English
Authors: Tamaredo Iván
Published: December 2017

The aim of the present paper is to test the claim that contact simplifies language (cf. Kusters, 2008) by comparing the domain of relative clause formation in British English, a L1 variety, and Indian English, a L2 variety. According to Hawkins (1999), the processing cost of relativizing a noun phrase increases down the Accessibility Hierarchy (Subject > Direct Object> Indirect Object > Oblique > Genitive> Object of Comparison) proposed by Keenan and Comrie (1977). Subject relative clauses are thus easier to process than direct object relatives, and so on. The results of a corpus study of the British and Indian components of the International Corpus of English show that the Accessibility Hierarchy has an indirect effect on the production of relative clauses in British English and Indian English: whereas the distribution of relative clauses with respect to the hierarchy is very similar in both varieties, the number of complex relatives, i.e., with coordination or further embedding, decreases in the lower positions in Indian English. These results thus suggest that language contact plays a significant role in relative clause use and accounts for certain differences between L1 and L2 varieties of English in this grammatical domain.
Intervención de tres estrategias educativas para cursos de programación en educación superior
Authors: Rojas López Arturo
Published: December 2017

El objetivo principal del presente trabajo es mostrar los resultados de intervenciones realizadas frente a grupo de tres estrategias educativas que permitieron tener mejores porcentajes de acreditación y calificación, así como disminución de deserción en comparación con los obtenidos en los últimos 8 años en los cursos iniciales de programación en la Universidad Tecnológica de Puebla. La primera intervención involucró la evaluación del pensamiento computacional a través de las habilidades de generalización, descomposición, abstracción, evaluación y diseño algorítmico; dicha evaluación fue la primera estrategia que permitió ofrecer a los estudiantes 10 escenarios de aprendizaje para el curso de Metodología de la programación. En la segunda intervención, 4 elementos fueron manipulados para ofrecer opciones de estudio en el curso de Programación, los cuales fueron contenidos, modos de trabajo, ritmos y tiempo y evaluación; fue la segunda estrategia con la intención de crear educación personalizada. En ambas intervenciones, el uso de la plataforma Moodle permitió exponer contenidos de aprendizaje y tener una herramienta extra para los estudiantes; la tercera estrategia fue en consecuencia el uso del b-learning. El principal resultado obtenido a través de encuestas voluntarias realizadas por los estudiantes fue la generación de una experiencia de aprendizaje que contribuyó a la motivación del estudiante en sintonía con las metas académicas de los cursos mencionados, por lo anterior se puede concluir que la combinación de las estrategias realizadas en las dos intervenciones mejoró los índices de acreditación y disminuyó el porcentaje de deserción, aunque aún hay trabajo por hacer para mejorar la calificación promedio.

El artículo se focaliza en el Instituto de Cinematografía (IC) de la Universidad Nacional del Litoral (UNL), Argentina, en torno a 1973–1974, no tanto en lo referido a la organización institucional e interna sino a cuatro cuestiones que lo singularizan: la asunción de nuevas autoridades alineadas con el programa de Reconstrucción Nacional del Peronismo en el gobierno; la recuperación del proyecto inicial del Instituto, el del período en que Fernando Birri lo dirigió (1956–1962); los vínculos con imaginarios y experiencias nacionales e internacionales, de América Latina y del llamado Tercer Mundo; el uso social del cine con fines educativos y políticos. El texto parte de la bibliografía existente sobre los conflictos y polémicas al interior del IC: con el director interventor durante 1969–1970, así como entre grupos de afinidad en torno al documental social, por un lado, y a la indagación de lenguajes y estéticas contemporáneas, por otro. Desde allí se propone una lectura del proyecto de 1973 en relación con esos y otros sucesos de los años previos y con la historia más larga del Instituto. Se anexan tres documentos internos de la gestión del IC de 1973–1974, hasta ahora inéditos.
Eje 4. Análisis de textos cinematográficos: en tanto representación de nuevas formas de sociabilidad y como acción social reflexiva: Nihilismo sociocultural y pérdida del mundo en Extension du domaine de la lutte (1999) de Philippe Harel y Michel Houellebecq
Authors: Ortega Joaquín Esteban
Published: December 2017

El peculiar nihilismo que atraviesa la obra literaria de Michel Houellebecq resulta ser no únicamente la posibilidad de un reflejo estético de nuestra vida social sino también una acción social reflexiva en sí misma susceptible de ser tenida en cuenta como conocimiento social. El presente artículo toma como referencia la adaptación cinematográfica que Philippe Harel realizó en 1999 sobre la novela del escritor francés titulada Extension du domaine de la lutte (Ampliación del campo de batalla) para constatar que nuestra época está favoreciendo la hibridación de los discursos y para cuestionar la posibilidad de vivir más allá de esa última ilusión que parece ser la de vivir sin ilusiones.
Detection of Shigella dysenteriae Type 1 in Milk by PCR
Authors: Gupta Pallavi , Dhaked Ram Kumar
Published: December 2017

Shigellosis is severest form of bacillary dysentery, a disease limited to humans and certain other primates. Conventional microbiological techniques used for the isolation and biochemical identification of microbes are time-consuming as well as labour intensive. Due to the fastidious nature of Shigella and the lengthy culture time, a rapid and sensitive system for the detection of bacteria is highly desirable. Nucleic acid-based techniques have enormous potential in the detection of biological weapons because of their specificity, sensitivity, and the speed with which results can be obtained. The application of polymerase chain reaction in sensitive detection of bacterial pathogens in direct food samples is largely affected by the quality of the template DNA. To overcome the shortcomings of conventional methods, we have defined simple method of sample preparation that facilitates PCR based detection of Shigella dysenteriae in milk. In present study, gene specific primers were designed to detect stxA gene. The genomic DNA extraction from the spiked milk was carried out by proteinase K, lysozyme, chloroform-isoamyl alcohol and heat treatments. The optimized extraction of DNA by addition of chloroform-isoamyl alcohol proved to be the most satisfactory  amongst all, with limit of detection of 2.0 x 103 cfu/ reaction and was completed in 4h.

Published: December 2017

The purpose of this study was to evaluate and compare the free-radical scavenging activity against DPPH stable radical and protective properties of the natural products SQGD and P. corylifolia and synthetic nitroxyl- free radical containing nitrosoureas SLENU and SLCNUgly against in vivo oxidative toxicity of antitumor drug CCNU. It was found statistically significant increase in the DPPH radical-scavenging capacity of both extracts with increase of radiation. The natural antioxidants were localised mainly in the organs and blood after EPR biodistribution study. All combinations of natural extracts/ synthetics agents exhibited considerably lower levels of Asc. radicals as compared to controls. It should be mentioned that the natural antioxidants possess higher oxidative protection in comparison with the synthetic antioxidants. Considerable decrease in ROS production in livers of mice was found after treatment with SQGD, P. corylifolia and SLENU, alone, compared to controls.In conclusion, because of well-expressed antioxidant activities of natural and synthetic antioxidants they might be used in the combination anticancer chemotherapy for reducing toxicity caused by anticancer drugs and/or low levels radiation therapy.

Published: December 2017

Synthetic organophosphorus compounds are highly toxic hence, widely used as pesticides, insecticides and chemical warfare agents. Organophosphorus hydrolase (OPH) is an organophosphotriester hydrolyzing enzyme; effectively hydrolyze a range of organophosphate esters. The objective of the present study was extraction and purification of OPH enzyme from Pseudomonas diminuta bacteria (soil microorganism) and to study kinetic properties of the purified enzyme. Enzyme was extracted and purified from bacteria by ammonium sulphate precipitation and ion exchange chromatography. Purity of an enzyme was determined by sodium dodecyl sulphate-polyacryamide gel electrophoresis (SDS-PAGE). Purified OPH enzyme specific activity was found to be 27.7 fold of 32.8U/mg protein, molecular weight of 72 Kda and it is a homodimer since it has shown a single band in SDS-PAGE separation. Maximum activity of the free OPH enzyme was found at Optimum pH 7.5 and temperature 35oC with the incubation time of 10 min. Michaelis constant (Km) and maximum velocity (Vmax) values of free OPH enzyme for methyl parathion as substrate was found to be 286.2μM and 2.5 μM/min respectively.
Simplified CFD based Approach for Estimation of Heat Flux over Wedge Models in High Speed Plasma Flows
Authors: Pillai L. Aravindakshan , Nair Praveen
Published: December 2017

Analysis of plasma flows at hypersonic velocity over blunt bodies is quite complex and challenging as it involves complex flow physics and carries several uncertainties. Simultaneous simulation of all the parameters as existing in re-entry flight puts constraints on most of the ground based experiments. Numerical simulations, on the other hand, require modelling of ionisation and real gas effects and prove to be computationally costly. This paper highlights the development of unstructured, cell centred second order accurate parallel version of in-house computational fluid dynamics (CFD) solver where high temperature equivalent properties used from Hansen’s 7 species model and establishment of a simplified procedure for estimation of heat flux over wedge models tested in Plasma Wind Tunnel facility, Vikram Sarabhai Space Centre. Numerical simulations were carried out for Plasma tunnel initially to get the flow properties inside the tunnel when operated without any model. A simplified CFD based approach is established for computing the heat flux over the bodies tested inside the tunnel and compared with the measured data. The comparison of numerical and measured values shows that the proposed methodology captures the flow physics and various parameters with acceptable levels of accuracy.
Development of Scale and Rotation Invariant Neural Network based Technique for Detection of Dielectric Contrast Concealed Targets with Millimeter Wave System
Authors: Kumar Bambam , Sharma Prabhat , Singh Dharmendra
Published: December 2017

The detection of concealed targets beneath a person’s clothing from standoff distance is an important task for protection and the security of a person in a crowded place like shopping malls, airports and playground stadium, etc. The detection capability of the concealed weapon depends on a lot of factors likes, a collection of back scattered data, dielectric property and a thickness of covering cloths, the hidden object, standoff distance and the probability of false alarm owing to objectionable substances. Though active millimeter wave systems have used to detect weapons under cloths, but still more attention is required to detect the target likes a gun, knife, and matchbox. To observe such problems, active V-band (59 GHz- 61 GHz) MMW radar with the help of artificial neural network (ANN) has been demonstrated for non-metallic as well as metallic concealed target detection. To validate ANN, the signature of predefined targets is matched with the signature of validated data with the help of the correlation coefficient. The proposed technique has good capability to distinguish concealed targets under various cloths.

Published: December 2017

The objective of the paper was to determine fuel consumption on elimination of the energy willow plantation with current mechanical methods with the use of the machine research model. The paper covers investigations of four machine units. The lowest fuel consumption (142.6 l∙ha−1) with the use of Meri Crusher MJS-2.0) did not ensure effectiveness of operation of this unit. Efficiency of elimination of the plantation in this case is only 36.4%. On the other hand, the highest consumption of diesel oil (776.4 l∙ha−1) was reported for FAO FAR model FV 4088, and the effectiveness of elimination was not satisfactory and it was 57.0%. The highest effectiveness of elimination of the plantation was reported for the model of a new machine. Fuel consumption in this case was 535.7 l∙ha−1 and the willow plantation elimination effectiveness was the highest and it amounted to 94.8%.

Modification of a recuperator construction with CFD methods
Authors: Ludwig Wojciech , Zając Daniel
Published: December 2017

The purpose of the work was initial modification of the construction of a commercially produced heat exchanger – recuperator with CFD (computational fluid dynamics) methods, based on designs and process parameters which were provided. Uniformity of gas distribution in the space between the tubes of the apparatus as well as the pressure drop in it were taken as modification criteria. Uniformity of the gas velocity field between the tubes of the heat exchanger should cause equalization of the local individual heat transfer coefficient values and temperature value. Changes of the apparatus construction which do not worsen work conditions of the equipment, but cause savings of constructional materials (elimination or shortening some parts of the apparatus) were taken into consideration.
A Novel Triple-Band Dipole Antenna for WLAN/WiMAX/LTE Applications
Authors: Shuai Chen-yang , Wang Guang-ming
Published: December 2017

In this paper, a novel triple-band dipole antenna is presented. The proposed antenna has a very simple structure and is easily designed. The idea of the antenna is based on the traditional wideband bow-tie dipole antenna. Via etching slots on the bow-tie patch, three bent dipoles with different lengths which correspond to different operating frequencies are formed. Hence, the triple-band antenna is generated. Each operating frequency band realizes wideband and can be adjusted almost independently. And the antenna is fed by a 50 Ω microstrip line and a wideband microtrip-to-coplanar-stripline (CPS) transition as a balun. The good performances of the proposed antenna are achieved by a mass of simulations and measurements. The measured results have a good agreement with the simulated ones. The results show that the proposed antenna obtains three bandwidths at 2.38~2.65 GHz (10.7 %), 3.17~4.08 GHz (25.1 %), and 4.75~6.00 GHz (23.2 %) with the reflection coefficient less than −10 dB. In addition, the stable gain and quasi-omnidirectional radiation patterns are obtained in the operating frequency bands. Therefore, the proposed antenna is suitable for WLAN/WiMAX/LTE applications.
Investigation of a L1-optimized choke ring ground plane for a low-cost GPS receiver-system
Authors: Zhang Li , Schwieger Volker
Published: December 2017

Besides the geodetic dual-frequency GNSS receivers-systems (receiver and antenna), there are also low-cost single-frequency GPS receiver-systems.

The multipath effect is a limiting factor of accuracy for both geodetic dual-frequency and low-cost single-frequency GPS receivers. And the multipath effect is for the short baselines dominating error (typical for the monitoring in Engineering Geodesy). So accuracy and reliability of GPS measurement for monitoring can be improved by reducing the multipath signal.

In this paper, the self-constructed L1-optimized choke ring ground plane (CR-GP) is applied to reduce the multipath signal. Its design will be described and its performance will be investigated.

The results show that the introduced low-cost single-frequency GPS receiver-system, which contains the Ublox LEA-6T single-frequency GPS receiver and Trimble Bullet III antenna with a self-constructed L1-optimized CR-GP, can reach standard deviations of 3 mm in east, 5 mm in north and 9 mm in height in the test field which has many reflectors. This accuracy is comparable with the geodetic dual-frequency GNSS receiver-system. The improvement of the standard deviation of the measurement using the CR-GP is about 50 % and 35 % compared to the used antenna without shielding and with flat ground plane respectively.
Le phénomène de la souffrance comme élément constitutif de la théophilosophie affirmative de Kierkegaard
Authors: Słowikowski Andrzej
Published: December 2017

This paper analyzes the problem of suffering in Kierkegaard’s thought on the basis of two main parts of his work: pseudonymous writings and upbuilding discourses. The main assumption is that Kierkegaard presents the problem of suffering differently in these two parts: in the pseudonymous writings from the viewpoint of the negative dialectic of paradox, and in the upbuilding discourses in terms of the positive dialectic of upbuilding. Therefore, the problem of suffering is examined separately in both these parts: in the pseudonymous writings as the phenomenology of suffering and in the upbuilding discourses as the hermeneutics of suffering. The most important conclusion is that the experience of suffering in Christianity has a completely positive dimension, because it is radically opposed to the experience of evil. The Christian suffering is in this approach, according to the pattern of Jesus Christ, an effect of the spiritual development of a human being in God and a place of God’s revelation in human existence. This understanding of Christian suffering leads to the discovery of a perspective of affirmative theophilosophy as an original interpretation of the Christian ideal presented by Kierkegaard.
On the Origins of Kierkegaard’s Climacus Writings and Paradox Christology
Authors: Schreiber Gerhard
Published: December 2017

By the spring of 1843, Kierkegaard’s Christology had changed fundamentally: he now attributed paradoxicality to the person of Jesus Christ. This essay presents a critical reconsideration of two of the most influential attempts within Kierkegaard research-those of Hayo Gerdes and Hermann Fischer-to explain the roots and background of Kierkegaard’s paradox Christology. Against these views, this essay will argue that the project undertaken in Kierkegaard’s Climacus writings had a different starting-point, namely, his reading of David Friedrich Strauss’ Christian Doctrine [Glaubenslehre].
Digitally Controlled AC Current Measurement and Protection Techniques
Authors: Turos László-Zsolt , Csernáth Géza , Hegyi István
Published: December 2017

This paper describes a cost effective AC current measurement method that avoids complex AC to DC current measurements by converting an amplified and rectified AC voltage drop across a shunt resistor to a duty cycle of a PWM signal. The current measurement chain output is fed into a microcontroller unit (MCU) and into a short circuit protection block that inhibits AC load drivers in case of overcurrent or short circuit events, overriding the state set by the MCU control algorithm. The authors present a mathematical model, simulations and a practical evaluation of custom-developed circuits that are capable to reach a convincing level of measurement precision. By counting a given number of consecutive AC periods, the effect of inrush current generated by inductive AC loads is filtered. The proposed solution allows inrush currents up to 3A, fitting the consumption range of AC control elements met in household application circuits, such as relays or solenoid valves.

The goal was to solve the problem in hardware level providing a fast method for stabilization. Using an FPGA circuit parallel with a microprocessor the control of the quadcopter becomes simpler the microprocessor can handle other tasks like area mapping or path calculation parallel with the stabilization hardware implemented on the FPGA. Sensor configuration and calibration was implemented on the FPGA along with the PID controller. The implemented circuit was tested in real time on the quadcopter.
A note on field-valued measures
Authors: Simone Anna De , Hroch Michal , Pták Pavel
Published: December 2017

We consider the Horn-Tarski condition for the extension of (signed) measures (resp., non-negative measures) in the setup of field-valued assignments. For a finite collection 𝓒 of subsets of Ω, we find that the extension from 𝓒 over the collection exp Ω of all subsets of Ω is implied by, and indeed equivalent to, a certain type of Frobenius theorem (resp. a certain type of Farkas lemma). This links classical notions of linear algebra with a generalized version of Horn-Tarski condition on extensions of measures. We also observe that for a general (infinite) 𝓒 the Horn-Tarski condition guarantees the extension of signed measures (here the standard Zorn lemma applies). However, we find out that the extensions for non-negative ordered-field-valued measures are generally not available.

We prove that the family of all quasi-continuous functions is strongly porous set in the family of all cliquish functions and that the family of all cliquish functions is strongly porous set in the family of all functions having the Baire property.

We prove also that the family of all Świątkowski functions is lower 2/3-porous set in the family of cliquish functions and the family of functions having the internally Świątkowski property is lower 2/3-porous set in the family of cliquish functions.

Present consequences of the post-war migration in the Czech borderland for regional development
Authors: Vaishar Antonín , Dvořák Petr , Nosková Helena , Zapletalová Jana
Published: December 2017

Czechia lost more than 3,000,000 inhabitants as a result of the WW II. Germans displaced from the borderland formed the largest part. The newcomers after 1945 were of a different character – without any relation to their new settlements. This population formed a special social milieu familiar with the socialist way of thinking and that of a suppressed middle class. The consequences of it are seen in demographic, economic, environmental and social areas. After 1989, the factories in the borderland were mostly closed down, armies left the territory, people were not prepared to start their own businesses. Large-scale landscape protection formed a new barrier. Tourism is not able to substitute for the decrease in employment. The hope in cross-border collaboration has been overestimated.
Monitoring of colonies and provisioning of rooks with nest material as a potential tool for stabilizing colonies and increasing nesting opportunities in the countryside. Project report
Authors: Slobodník Roman , Tulis Filip , Chavko Jozef , Lengyel Jozef
Published: December 2017

The rook is a species inhabiting open agricultural landscape whose non-active nests are also used by other bird species for nesting. It is the decline in rook colonies that has been posited as one of the reasons for decrease in the red-footed falcon (Falco vespertinus) population in Slovakia since the 1970s. During the period from 2012 till 2016, four monitorings of rook colonies were carried out in south-western Slovakia (Diakovce, Nitrianska Osada, Sokolce and Tvrdošovce). In the colony at Tvrdošovce, supporting activity involving provisioning of rooks with nest material was under way from 2014 until 2016. While the colonies at Diakovce and Nitrianska Osada have been showing a slight decrease in the number of nesting rooks, despite larger interannual differences the colony at Sokolce has been showing an upward trend. The size of the colony at Tvrdošovce has been stable since the beginning of the supporting activity. This activity had a statistically significant positive effect on the width of rook nests. In 74 cases in the studied rook colonies we have recorded nesting by three other bird species – Eurasian kestrel (Falco tinnunculus) 43.8%, western jackdaw (Corvus monedula) 39.7% and long-eared owl (Asio otus) 16.4%. In 2015 two female redfooted falcons were observed in the colony at Tvrdošovce.
Agricultural utilisation and potential suitability of the Sysľovské polia Special Protection Area (south-western Slovakia) landscape in relation to the habitat requirements of the red-footed falcon (Falco vespertinus)

Intensification of land use in an agricultural landscape significantly affects biodiversity also in protected areas. This can be observed in the Sysľovské polia Special Protection Area in relation to the occurrence of the red-footed falcon (Falco vespertinus). The objective of this study was to evaluate the landscape structure and suitability of agrotechnical procedures for the habitat demands of this species in the course of the period from 2004 until 2017. The utilisation was assessed on the basis of four landscape elements representation in 1949 and 2017. The next step was analysis of landscape patches. The aim was to quantify the diversity and the spatial structure of the landscape mosaic using Shannon’s Diversity Index and Evenness Index as well as Simpson’s Diversity Index and Evenness Index and spatial pattern analysis in the Fragstats software programme. Assessment of crop suitability was carried out according to the following criteria: representation of positive/negative agricultural crops, diversity of crops in crop rotation, and (non-)observance of crop rotation. It was found that the agricultural landscape use did not change significantly. The study area has been used as an intensively-farmed agricultural landscape for a long time. The landscape elements have remained almost identical, with dominance of arable land. Differences emerged in the analysis of the micropatches, which are represented by natural hedgerows consisting of various species of trees, shrubs and grasses. The results show a decrease in the diversity of patches and changes in the structure of the landscape patches, which may be important in terms of the preservation of the habitat of fauna which form an important part of the F vespertinus diet. On the basis of the evaluation of the suitability of agricultural crop growing, we found that there were some areas showing negative values in all the criteria, and thus they require changes in the crop rotation focusing on increasing positive crop diversity and the share of grassland.
On Seduction in Theatre Performance or the (Im)Possibility of a Demythisation
Authors: Piroşcă Alin-Daniel
Published: December 2017

Seduction doesn’t really refer to love. In fact, it isn’t at all directly related to love, but as the word’s etymology suggests, it is an intellectual act that means “to lead on a different path”, “to corrupt”. Starting from this point and considering it in regard to the theatre performance and audience, our main purpose in this paper is to identify the elements involved in the process of seduction that takes place in the performance space, but also the role of each one of these elements. We will make a series of approaches on a theoretical level, involving some exercises in semiotics, in an attempt to reformulate the relation between the performance and the audience. This paper asserts that the performance is acting the part of the seducer and the audience is the one being seduced, but also that there is a secret involved in this relation, enlarging the aesthetical notions related to the theatre performance, through the relevant functions of desire and intimacy.
Time’s Tricephalous Image in Macbeth by William Shakespeare
Authors: Conţiu Lia Codrina
Published: December 2017

Influenced by the Humanist movement, Shakespeare is preoccupied with time, illustrating it in his lyrics and dramaturgy. If in comedies time has a regenerative character, in the Shakespearean tragedies “the clock” ticks continuously, it is the soundtrack that fulfills the destiny of the character. And Macbeth is perhaps the best example in this respect. Macbeth is hypnotized and haunted by time. Hypnotized by the imagination of a possible future and haunted by a past full of blood and crimes. The hero lives between imagination and memory, and the main catalyst of the play is the tragic interaction between Macbeth and time, with all the psychological and physical tensions that derive from there. The main impact of time on Shakespeare’s tragic heroes is achieved by the actual actions of time that exposes and amplifies tragic defects of heroes (in Macbeth’s case - ambition). As in the Renaissance, myths, images and signs were used in poetics and literature to indicate a teaching, a moral, Shakespeare includes in his work symbols taken from the iconography and mythography available at that time, such as time’s tricephalous image around which Macbeth is “shaped”.
Artistic Forms of Speech in a One-Person Show
Authors: Scutariu Irina
Published: December 2017

This one-man show type of performance is a theatrical project in which the actor Alexandru Dobinciuc, a final year master’s student at the George Enescu University of Arts, Department of Theatre was involved. We aim to describe both the specific evolution of a character in a one-person show, and the strategies and technical means used in this type of show, such as scenography, costumes, music and video projections. The latter element is what makes this show exciting; from a purely technical standpoint, the show has the benefit of being easy to relocate. Nowadays, actors need these means of practicing artistic skills: any actor should include in his repertoire this type of show to be able to demonstrate his artistic talents. We use the metaphor of Dialogue of the arts in contemporary theatre to support faculties in the field of arts and young actors who are no longer eligible for indefinite employment contracts, even if they play in an institution-based cultural environment. (The highly debated issue of vacancies in theatres is not part of our discussion.) It is worth mentioning that the actor with whom I have worked on this project is one of the few graduates who were hired by a theatre institution. He is employed by the Mihai Eminescu Theatre in Botoşani.
Aspects of the Comic in the Performances for Children

In this paper, I wanted to prove that humor, comic and appealing characters, like animals, or music, have to enchant the child, and that everything that is created for him must be on the highest possible artistic level. These are the attributes of a good performance for children.
Rape and Repentance in Two Medieval Motets
Authors: Saltzstein Jennifer
Published: December 2017

Two thirteenth-century vernacular motets copied side by side in the Montpellier Codex tell a story of sin and repentance. In one a shepherd rapes a maiden, while in the other a penitent begs the Virgin Mary to forgive a great sin. The music of these two motets is nearly identical: one is a contrafactum of the other, and represents a conscious narrative continuation of the first. This article offers a close reading of this unusual pair of motets, interpreting their texts and polyphonic musical settings in the context of other motets, the pastourelle song genre, their liturgical tenor, the technique of contrafacture, the chanson pieuse, and the intertextual refrain repertory. The two motets constitute a medieval exploration of the boundary between seduction and rape, and the spiritual consequences of its transgression. Having placed the story told by the motets in the context of medieval attitudes toward rape in both legal and pedagogical spheres, I close by reflecting on the ethics of listening to artistic representations of violence for both medieval and modern audiences.
Bodies, Biopolitics, and Mushrooms Once Again
Authors: Phelps Hollis
Published: December 2017

In this short essay, I respond to Donovan Schaefer's response to my paper, "Do Mushrooms Have Religion, Too?" Continuing the line of critique originally formulated, I suggest that Schaefer's exclusion of non-animal life from the realm of bodies conceals a biopolitical decision.
