Influence of Interface Gap on the Stress Behaviour of Smart Single Lap Joints Under Time Harmonic Load
Authors: Ivanova Jordanka , Valeva Varbinka
Published: July 2017

Adhesive joints are frequently used in different composite structures due to their improved mechanical performance and better understanding of the failure mechanics. The application of such structures can be seen in aerospace and high technology components. The authors developed and applied modified shear lag analysis to investigate the hygrothermalpiezoelectric response of a smart single lap joint at environmental conditions (with/without an interface gap along the overlap zone) and under dynamic time harmonic mechanical and electric loads. The main key is the study of the appearance of possible delamination along the interface. As illustrative examples, the analytical closed form solution of the structure shear and the axial stresses response, as well as the interface debond length, including influence of mechanical, piezoelectric, thermal characteristics and frequencies is performed and discussed. All results are presented in figures. The comparison of the shear stress and electric fields for both cases of overlap zone (continuous or with a gap) is also shown in figures and discussed.

Rapid Design Optimization of Multi-Band Antennas by Means of Response Features
Authors: Kozieł Sławomir , Bekasiewicz Adrian
Published: July 2017

This work examines the reduced-cost design optimization of dual- and multi-band antennas. The primary challenge is independent yet simultaneous control of the antenna responses at two or more frequency bands. In order to handle this task, a feature-based optimization approach is adopted where the design objectives are formulated on the basis of the coordinates of so-called characteristic points (or response features) of the antenna response. Due to only slightly nonlinear dependence of the feature points on antenna geometry parameters, optimization can be attained at a low computational cost. Our approach is demonstrated using two antenna structures with the optimum designs obtained in just a few dozen of EM simulations of the respective structure.
Application of Improved Robust Kalman Filter in Data Fusion for PPP/INS Tightly Coupled Positioning System
Authors: Li Zengke , Yao Yifei , Wang Jian , Gao Jingxiang
Published: July 2017

A robust Kalman filter improved with IGG (Institute of Geodesy and Geophysics) scheme is proposed and used to resist the harmful effect of gross error from GPS observation in PPP/INS (precise point positioning/inertial navigation system) tightly coupled positioning. A new robust filter factor is constructed as a three-section function to increase the computational efficiency based on the IGG principle. The results of simulation analysis show that the robust Kalman filter with IGG scheme is able to reduce the filter iteration number and increase efficiency. The effectiveness of new robust filter is demonstrated by a real experiment. The results support our conclusion that the improved robust Kalman filter with IGG scheme used in PPP/INS tightly coupled positioning is able to remove the ill effect of gross error in GPS pseudorange observation. It clearly illustrates that the improved robust Kalman filter is very effective, and all simulated gross errors added to GPS pseudorange observation are successfully detected and modified.
Preconditions for Emergence of Lithuanian Clusters: from Informal Cooperation to Its Legitimation
Authors: Grumadaitė Kristina , Jucevičius Giedrius
Published: July 2017

This paper reveals preconditions for the emergence of clusters as self-organisation based industrial systems in a context, in which cooperation traditions are insufficiently developed. These preconditions reflect the principles of the emergence of self-organising complex adaptive systems that are analysed in the complexity theory. Those principles are based on the initiation of non-equilibrium and its purposeful direction into the creation of a new order. This paper highlights the main external and internal tensions that influence informal or formal clustering of enterprises, while various change agents perform different roles making self-organising processes to occur.

We first indicate differences that exist in the implementation of EU competition law at the national level, given the unified framework of EU competition policy. In a next step, we discuss recent cases in both countries and indicate how historical developments and economic factors influence decision making and case law. We also discuss recent developments of the national competition policy regimes and indicate how the digital economy might shape competition policy in the future.
Changes in Responsibilities and Tasks of Universities in Regional Innovation Ecosystems
Authors: Birkner Zoltán , Máhr Tivadar , Berkes Nora Rodek
Published: July 2017

Innovation process research is changing. In addition to the former territorial approach (examining countries or regions), the description of innovation cooperation in local areas is becoming more and more accepted. Instead of the innovation ability of the traditional large enterprises, research has begun to study the role of small and medium-sized enterprises, non-governmental organizations, local governments, and educational institutions (especially universities), which foreshadows the development of a new innovation system. In 2015, we conducted a study focusing on the civil and corporate relations of a major university. We tried to determine the new directions based on the economic and social cooperation as well as to search for the practical implementation of the theoretical helixes in these interactions. We came to the conclusion that universities not only are determinative according to the triple helix model but also have a prominent role in the creation of new innovation ecosystems, particularly in a well-defined geographical area.
Economic Effects of Renewable Energy Technologies
Authors: Maradin Dario , Cerović Ljerka , Mjeda Trina
Published: July 2017

Rapid economic development has resulted in the more frequent use of renewable energy technologies. On the other hand, the production and use of renewables fosters the development of new technologies, creating many new opportunities for entrepreneurial-minded individuals and, consequently, the economy in general. Renewable energy technologies have a multiplier effect in spurring the economy and the development of not only the energy sector but also all the supporting activities related to such industry. The purpose of this research is to analyse both the positive and the negative economic effects of investing in various renewable technologies, as well as to confirm, by means of the energy-economy model, the benefit of such technologies in boosting the economy.
Electrical resistivity and spatial variation in agriculture terraces: statistical correlation between ert and flow direction algorithms
Authors: Fernandes J. , Bateira C. , Costa A. , Fonseca B. , Moura R.
Published: July 2017

The construction of earthen embankment terraces in the Douro Region raises a set of problems related to hydrological processes. The main objective of this study is the evaluation of the spatial variation of electrical resistivity in agriculture terraces at Douro valley (Portugal). To achieve this objective, two variables are analysed, the soil electrical resistivity and the flow direction algorithm. In a field survey we recorded 13 electrical resistivity profiles. The contributing area was calculated with the algorithms D∞ (Deterministic Infinity Flow) and MFD (Multiple Flow Direction) and the results are the base of the internal runoff modelling, both supported by the digital elevation model with a spatial resolution of 1m2. A correlation between the spatial variation of the soil electrical resistivity represented by the standard deviation of the electrical resistivity for each profile and the average value of the contributing area coincident with each profile was established. The electrical resistivity standard deviation seems to be moderately well correlated according to the D∞ algorithm at about 1m of depth, and it has a good correlation at 1,5m to 2m of depth with the MFD algorithm. Taken together, the results show a significant positive statistical correlation between the electrical resistivity standard deviation and the contributing areas (MFD and D∞) depending on the soil depth.
Process analysis transit of municipal waste. Part I - International provisions of law
Authors: Starkowski Dariusz , Bardziński Paweł
Published: July 2017

One of the crucial reasons of the system changes of waste management in our legal system in Poland was a need to implement solutions and mechanisms that are applied in the European Union. At the European Union law level, a Directive 2008/98/EC of the European Parliament and of the Council of 19 November 2008 on waste and repealing certain Directives constitutes a basic legal document described in this part of the article. The essential idea of the quoted directive is creating legal measures, promotion of eliminating waste production and treating it as a source instead. Achievement of these assumptions requires providing segregation at source and recycling of the main waste streams above all. It is necessary to encourage this action and support the reuse of products and waste utilization. Indicated international legal instruments are of primary importance for internal rules, which shall be constructed in a way that enables the achievement of goals determined by the EU law. Legal-organizational internal systems associated with the management of waste have undergone substantial changes from 2010. National legal provisions will be presented in the second part of the article.

Authors: Wszelaczyńska Elżbieta , Pobereżny Jarosław , Gościnna Katarzyna , Chmielewski Jarosław , Knapowski Tomasz , Kozera Wojciech , Majcherczak Edward
Published: July 2017

The aim of the research was to define changes in the content of NO3¯ determined by the environment and processing in products from five cultivars of carrot, orange in colour. Besides this, in the research, the human intake of toxic compounds found in processed foods was also assayed. All the processed foods were produced at laboratory scale compliant with the applicable guidelines and norms. The content of nitrates in processed foods depended significantly on the genetic conditions of material and on the processing method. Of all the cultivars under study, ‘Karotan’ was least applicable to processing since, irrespective of the processing method, the lowest decrease in nitrates was reported for that cultivar. The consumption of processed foods from the cultivars of carrot studied is not hazardous to consumer health, since the value of the ADI in adult, Acceptable Daily Intake, is not exceeded.
The impact of brick (Agrochola circellaris Hufn.) and owlet moths (Lepidoptera: Noctuidae) on the health of seeds of field elms (Ulmus minor Mill.) in the landscape parks of the Świętokrzyskie Province
Authors: Bąk-Badowska Jolanta , Żeber-Dzikowska Ilona , Chmielewski Jarosław
Published: July 2017

In the period of 2012-2013, a research was conducted to investigate the insects damaging the seeds of field elm (Ulmus minor Mill.). The aim of the research was to specify the damages to field elm seeds caused mainly by the brick (Agrochola circellaris) and to indicate the possible dependence between the number of damaged seeds by the caterpillars of this moth and stand density. The research was conducted in the areas of Cisów-Orłowiny Landscape Park (C-OLP) and Nida Landscape Park (NLP) in the Świętokrzyskie Province. In both parks, there were two test stands situated, each of which covered the material collected from the trees. The number of field elms ranged from four to six. Furthermore, a sample of 300 seeds were randomly collected from each tree. The elms in Cisów-Orłowiny Landscape Park were observed in full density stands (fully stocked stands); however, these trees in Nida Landscape Park were growing in loose density stands (under-stocked stands). In total, there were 12,000 seeds collected from 20 trees. The analysis of the collected research material demonstrated that 436 seeds from the field elms (Ulmus minor) were damaged by the brick (Agrochola circellaris). It constituted 3.6% of the total number of collected samples (Table 1). In the seed samples collected from the test stands in Cisów-Orłowiny Landscape Park, the damages caused by the caterpillars of the brick moth ranged between 0.8% and 2.9%. In the case of seed samples collected from Nida Landscape Park, the damages caused by the caterpillars of the brick moth were greater and ranged between 4.1% and 6.5%. The percentage of undamaged seeds ranged between 94.4% in Cisów-Orłowiny Landscape Park and 84.7% in Nida Landscape Park, which constituted, on an average, 89.5% for both parks. The 6.8% of the seeds were also damaged by other insects. The results of the research showed the dependence between the number of field elm seeds damaged by the brick Agrochola circellaris and the stand density (Table 2). The seeds collected from trees growing in the Nida Landscape Park in loose density stands (under-stocked stands) were twice as frequently damaged than those collected from the trees growing in Cisów-Orłowiny Landscape Park in full density stands. Also, the damages caused by other insects were greater among the seeds collected from trees growing in loose density stands than in full density stands (Table 1).

Published: July 2017

Objective: The purpose of this study is to demonstrate the synchronous bilateral breast irradiation radiotherapy technique using a single isocenter. Materials and Methods: Six patients of synchronous bilateral breast were treated with single isocenter technique from February 2011 to June 2016. All the patients underwent a CT-simulation using appropriate positioning device. Target volumes and critical structures like heart, lung, esophagus, thyroid, etc., were delineated slice by slice in the CT data. An isocenter was placed above the sternum on the skin and both medial tangential and lateral tangential of the breast / chest wall were created using asymmetrical jaws to avoid the beam divergence through the lung and heart. The field weighting were adjusted manually to obtain a homogenous dose distribution. The planning objectives were to deliver uniform doses around the target and keep the doses to the organ at risk within the permissible limit. The beam energy of 6 MV or combination of 6 MV and 15 MV photons were used in the tangential fields according to the tangential separation. Boluses were used for all the mastectomy patients to increase the doses on the chest wall. In addition to that enhanced dynamic wedge and field in field technique were also used to obtain a homogenous distribution around the target volume and reduce the hot spots. The isocenter was just kept on the skin, such that the beam junctions will be overlapped only on the air just above the sternum. Acute toxicity during the treatment and late toxicity were recorded during the patient’s follow-up. Results: During the radiotherapy treatment follow-up there were no acute skin reactions in the field junctions, but one patient had grade 1 esophagitis and two patients had grade 2 skin reactions in the chest wall. With a median follow-up of 38.5 months (range: 8 - 49 months), no patients had a local recurrence, but one patients with triple negative disease had a distant metastases in brain and died after 28 months. Conclusions: We were able to successfully treat the synchronous bilateral breast using single isocenter radiotherapy while keeping the lung and heart doses within the acceptable dose limits. During the treatment follow-up there were no symptoms of acute skin reactions in the field junction.
Weighting alternative for water stable isotopes: Statical comparison between station- and firn/ice-records
Authors: Hatvani István Gábor , Kern Zoltán
Published: July 2017

It is generally accepted that ice cores archive amount-weighted water stable isotope signals. In order to achieve an improved understanding of the nature of water stable isotope signals stored in ice cores annual δ18O and δ2H averages (i.e. amount-weighted) were calculated for two Antarctic meteorological stations, Vernadsky and Hal­ley Bay, using monthly precipitation amount and monthly net accumulation as weights, respectively. These were then compared with the annual mean δ18O δ2H and records of the nearest available ice cores. In addition, at the stations, both arithmetic means (i.e. time-weighted) and amount-weighted (precipitation amount and net accumulation used as weights) annual air temperature averages were calculated and then compared to amount weighted annual mean δ18O and δ2H using correlation- and regression analyses. The main hypothesis was that amount weighted annual mean water isotope and temperature records from the stations would be able to replicate the annual water isotope signal stored in ice cores to a higher degree. Results showed that (i) amount weighting is incapable of ameliorating the signal replication between the stations and the ice cores, while arithmetic means gave the stronger linear relationships; (ii) post depositional processes may have a more determining effect on the isotopic composition of the firn than expected; and (iii) mean annual air temperature provided the closest match to ice core derived annual water isotope records. This latter conveys a similar message to that of recent findings, in as much as ambient temperature, via equilibrium isotope fractionation, is imprinted into the uppermost snow layer by vapor exchange even between precipitation events. Together, these observations imply that ice core stable water isotope records can be a more continuous archive of near-surface temperature changes than hitherto believed.
The community feeling versus anxiety, self-esteem and well-being – introductory research
Authors: Kałużna-Wielobób Alina
Published: July 2017

In accordance with the concept of A. Adler (1933/1986) - the community feeling is an individual characteristic which is relatively stable throughout life. It refers to an inner relationship of one person with other people: a feeling of unity with others or separation from others. People with high community feeling are motivated in their actions by striving towards the common good, whereas people with low community feeling intend to exhibit their superiority over others in their actions, which would allow them to compensate for their inner feeling of inferiority. On the basis of the Adler concept the following hypotheses were formulated: There is a negative connection between the community feeling and anxiety. The community feeling is positively connected with self-esteem and psychological well-being. A slight increase in the community feeling can be observed with age. The community feeling increases in the age of middle adulthood. 585 people between 20 to 65 years of age were examined. Methods: Community Feeling Questionnaire, State-Trait Anxiety Inventory, Rosenberg Self-Esteem Scale, Ryff Scales of Psychological Well-Being. The hypotheses assumed were verified.
Organizational roles and the work and organizational engagement
Authors: Borkowska Anna , Czerw Agnieszka
Published: July 2017

Purpose - The article aims to attempt to define the work and organization engagement of the employees of one of the exclusive hotel spa in Poland. The present paper proposes that organizational roles taken by employees differentiate symptoms of their engagement. The research aims to test the hypothesis and to show the differences at the level of concepts and behaviors. Design/methodology/approach - The following study is an attempt to define the work and organizational engagement of employees of one of the exclusive SPA (sanus per aquam) hotels in Poland. The study was conducted using qualitative methods in the form of individual interviews and a group interview. The study described is part of a bigger project implemented in a Hotel. One department within the hotel, the kitchen of the main restaurant, was chosen for analysis. As such, opinions of two managers of various ranks (the Chef and the Deputy Manager of the Hotel) and seven persons from the aforementioned department are presented in this paper. Findings - Data analysis allowed us to conclude that organizational roles performed by employees may, in an influential way, shape the level and mental representation of the work and organizational engagement. Our results show that the higher position an employee has in the organizational hierarchy, the better is his/her understanding and the bigger is level of engagement both in work and in the organisation. What’s more, higher organizational role is conducive to mixing these two perspectives, and the lower role makes them clearly separated.
Love Styles in the Context of Life History Theory
Authors: Marzec Magdalena , Łukasik Andrzej
Published: July 2017

The evolutionary function of love is to create a strong bond between the partners with reproduction in view. In order to achieve this goal, humans use various sexual/reproductive strategies, which have evolved due to specific reproductive benefits. The use of particular strategies depends on many factors but one of the most important is early childhood experiences, on which life history theory (LHT) focuses. John Lee (1973) identified 6 basic love styles: eros, ludus, storge, pragma, agape, and mania. Our goal was to check whether love styles may be treated as sexual/reproductive strategies in the context of LHT - slow or fast strategy. In our study (N = 177) we found that people who prefer the slow reproductive strategy are inclined to show passionate, pragmatic and friendly love, and those who prefer the fast strategy, treated love as a game. A low level of environmental stress in childhood results in preferring eros, storge and agape love styles, belonging to the slow strategy, and a high one results in preferring ludus, which belongs to the fast strategy. People representing eros, storge or pragma styles have restricted sociosexual orientation so they prefer long-term relationships, whereas those with the ludus style are people with unrestricted orientation, preferring short-term relationships. Besides, storge, agape and pragma seem to determine preferring qualities connected with parental effort in one’s partner, mania - with mating effort, and eros - with both kinds of effort. No correlation was found between the love style and the number of children.
Narcissism and self-esteem revisited: The relationships between the subscales of the NPI and explicit/implicit self-esteem
Authors: Pilch Irena , Hyla Magdalena
Published: July 2017

The results of the previous research which tried to investigate links between self-esteem and narcissism in search of the source of narcissistic fragility are not consistent. The aim of the study was to contribute to the understanding of this complex relation by assessing relationships between the four facets of grandiose narcissism measured by the NPI and the two kinds of self-esteem i.e. explicit (ESE) and implicit (ISE), and by comparing the results with theoretical models. The Implicit Relational Assessment Procedure, a more recent measure based on response latency, was used to assess ISE. The analysis confirms the reports on NPI heterogeneity. Different relationships between the particular facets of narcissism and ESE/ISE were observed. These differences indicate that composite measures of narcissism and ISE do not reflect the entire complexity of the phenomena. The results provide support for the two theoretical models i.e. the global marker model and the mask model.
Reliability of the Discounting Inventory: An extension into substance-use population
Authors: Malesza Marta , Maczuga Maria
Published: July 2017

Recent research introduced the Discounting Inventory that allows the measurement of individual differences in the delay, probabilistic, effort, and social discounting rates. The goal of this investigation was to determine several aspects of the reliability of the Discounting Inventory using the responses of 385 participants (200 non-smokers and 185 current-smokers). Two types of reliability are of interest. Internal consistency and test-retest stability. A secondary aim was to extend such reliability measures beyond the non-clinical participant. The current study aimed to measure the reliability of the DI in a nicotine-dependent individuals and non-nicotine-dependent individuals. It is concluded that the internal consistency of the DI is excellent, and that the test-retest reliability results suggest that items intended to measure three types of discounting were likely testing trait, rather than state, factors, regardless of whether “non-smokers” were included in, or excluded from, the analyses (probabilistic discounting scale scores being the exception). With these cautions in mind, however, the psychometric properties of the DI appear to be very good.

Authors: Foo Fatt Mee , Hassan Siti Aishah , Talib Mansor Abu , Zakaria Noor Syamilah
Published: July 2017

This study aims to measure the latent mean difference in perfectionism and marital satisfaction by counseling help-seeking attitudes. The respondents were 327 married graduate students from a research university in Malaysia. An online self-administered questionnaire was used to collect the data. The respondents completed the Almost Perfect Scale- Revised, Dyadic Almost Perfect Scale, Marital Satisfaction Scale, and Attitudes toward Seeking Professional Psychology Help Scale. Confirmatory factor analysis was used to examined the instruments and the results indicated that construct validity were achieved. The latent mean difference in perfectionism and marital satisfaction by counseling help-seeking attitudes were tested using multigroup invariance analysis. The respondents with negative attitudes toward counseling help-seeking (n = 159) reported a higher latent mean in perfectionism but a lower latent mean in marital satisfaction compared to those with positive attitudes toward counseling help-seeking (n = 168). The implications of these findings for counseling services are discussed.
A first principles study of energetics and electronic structural responses of uranium-based coordination polymers to Np incorporation
Authors: Saha Saumitra , Becker Udo
Published: July 2017

Recently developed coordination polymers (CPs) and metal organic frameworks (MOFs) may find applications in areas such as catalysis, hydrogen storage, and heavy metal immobilization. Research on the potential application of actinide-based CPs (An-CP/MOFs) is not as advanced as transition metal-based MOFs. In order to modify their structures necessary for optimizing thermodynamic and electronic properties, here, we described how a specific topology of a particular actinide-based CP or MOF responds to the incorporation of other actinides considering their diverse coordination chemistry associated with the multiple valence states and charge-balancing mechanisms. In this study, we apply a recently developed DFT-based method to determine the relative stability of transuranium incorporated CPs in comparison to their uranium counterpart considering both solid and aqueous state sources and sinks to understand the mechanism and energetics of charge-balanced Np5+ incorporation into three uranium-based CPs. The calculated Np5++H+ incorporation energies for these CPs range from 0.33 to 0.52 eV, depending on the organic linker, when using the solid oxide Np source Np2O5 and U sink UO3. Incorporation energies of these CPs using aqueous sources and sinks increase to 2.85–3.14 eV. The thermodynamic and structural analysis in this study aides in determining, why certain MOF topologies and ligands are selective for some actinides and not for others. This means that once this method is extended across a variety of CPs with their respective linker molecules and different actinides, it can be used to identify certain CPs with certain organic ligands being specific for certain actinides. This information can be used to construct CPs for actinide separation. This is the first determination of the electronic structure (band structure, density of states) of these uranium- and transuranium-based CPs which may eventually lead to design CPs with certain optical or catalytic properties. While the reduction of the DFT-determined-bandgap goes from 3.1 eV to 2.4 eV when going from CP1 to CP3, showing the influence of the linker, Np6+ incorporation reduces the bandgap for CP1 and CP3, while increasing it for CP2. The coupled substitution of U6+→Np5++H+ reduces the bandgap significantly, but only for CP3.
A new optical sensor for spectrophotometric determination of uranium (VI) and thorium (IV) in acidic medium
Authors: Elhefnawy O. A.
Published: July 2017

A spectrophotometric method was developed for U(VI) and Th(IV) determination in acidic medium by using proposed optical sensor. This sensor is base on the complexation reaction of the ionophore midodrine hydrochloride (L) with U(VI)/Th(IV) in plasticized (o-NPOE) high molecular weight (PVC). Several parameters such as effect of acidic medium, response time and sensor compositions were studied. The determination of the complexes stoichiometry was also studied using Job’s method. The complexes stoichiometry were measured at the absorbance spectra 302 nm and the results were found to be 1:1 for both complexes U(VI)-L and Th(IV)-L. The complexation reaction was extremely rapid at room temperature; it takes 5, 10 min to complete the complexation reaction in U(VI) and Th(IV), respectively. Under the optimum conditions the calibration curves of U(VI)/Th(IV) determination, have good linearity at different acidic medium nitric, sulfuric, and phosphoric acids with low detection and quantification limits. The accuracy and precision studies proved that the proposed optical sensor is valid and qualified for U(VI)/Th(IV) spectrophotometric determination in different acidic medium. The selectivity of the proposed optical sensor was studied. The proposed optical sensor was applied successfully for U(VI)/Th(IV) determination in research and development (R&D) nuclear waste samples with satisfactory results. A comparative study of the proposed optical sensor with other previous spectrophotometric sensors for U(VI)/Th(IV) determination, proved the high efficiency of the proposed optical sensor, that it presents wide linear range and low detection limit. The proposed optical sensor could be applied for a quantitative determination of U(VI)/Th(IV) in acidic waste samples.
Translating Conceptual Metaphor: The Processes of Managing Interlingual Asymmetry
Authors: Massey Gary , Ehrensberger-Dow Maureen
Published: July 2017

Encountered at all levels of language, conceptual asymmetries between source and target languages present translators with fundamental challenges that require problem awareness, problem identification and problem solving. A case in point is conceptual metaphor in translation. Versions of conceptual metaphor theory have been applied in various productoriented studies of how translators deal with the challenge of metaphor in translation. However, there is potential in combining product-oriented approaches with techniques used to access translators’ cognitive processes, although process-oriented studies on how conceptual metaphor is re-conceptualised or re-mapped in translation are still rare. Building on an exploratory study carried out at our institute, in which findings from translation process data suggest that experience and/or training appears to be a main factor in handling conceptual metaphor, we present some salient features of re-mapping metaphor. Triangulating data from target-text products, keystroke logs and retrospective verbal commentaries collected under very similar conditions in a laboratory setting, we analyse how translators at different levels of experience handle two complex conceptual metaphors. The results appear to suggest that complex metaphor might indeed be culturespecific. They also potentially indicate that re-mapping practices are a function of experience and that re-mapping to a source-language target domain could create more uncertainty than generic-level re-mapping. Both findings hold pedagogical implications, which are discussed together with some methodological issues.
Aiming for Cognitive Equivalence – Mental Models as a Tertium Comparationis for Translation and Empirical Semantics
Authors: Sickinger Pawel
Published: July 2017

This paper introduces my concept of cognitive equivalence (cf. Mandelblit, 1997), an attempt to reconcile elements of Nida’s dynamic equivalence with recent innovations in cognitive linguistics and cognitive psychology, and building on the current focus on translators’ mental processes in translation studies (see e.g. Göpferich et al., 2009, Lewandowska-Tomaszczyk, 2010). My approach shares its general impetus with Lewandowska-Tomaszczyk’s concept of re-conceptualization, but is independently derived from findings in cognitive linguistics and simulation theory (see e.g. Langacker, 2008; Feldman, 2006; Barsalou, 1999; Zwaan, 2004). Against this background, I propose a model of translation processing focused on the internal simulation of reader reception and the calibration of these simulations to achieve similarity between ST and TT impact. The concept of cognitive equivalence is exemplarily tested by exploring a conceptual / lexical field (MALE BALDNESS) through the way that English, German and Japanese lexical items in this field are linked to matching visual-conceptual representations by native speaker informants. The visual data gathered via this empirical method can be used to effectively triangulate the linguistic items involved, enabling an extra-linguistic comparison across languages. Results show that there is a reassuring level of inter-informant agreement within languages, but that the conceptual domain for BALDNESS is linguistically structured in systematically different ways across languages. The findings are interpreted as strengthening the call for a cognition-focused, embodied approach to translation.

Published: July 2017

Blister aneurysms are a separate class of vascular malformations with a unique etiopathogenesis and clinical profile, elusive to radiological imaging and complex to manage. Unless identified and managed appropriately they often lead increased morbidity intra and post operatively. They are commonly reported in internal carotid artery. We are reporting a rare case of intraoperatively diagnosed blister aneurysm of the anterior cerebral artery, the management options and the importance of constant vigilance in cases where the aneurysm appears unruptured intraoperatively.

Vertebral body may get displaced anterior or posteror with elements of rotation. However, burst cervical spine vertebral fracture may migrate anteriorly and posteriorly simultaneously. However anterior displaced fragment forming armor like mass is very rare. Similarly, the posteriorly propelled fragments migrating caudally and posterolaterally producing a large osseous mass inside spinal canal mimicking bony tumour causing severe cervical canal stenosis and presenting with marked myelopathy is extremely rare. To the best knowledge of authors, association of such traumatic dual pathology represents first of its kind in western literature, who was neglected early medical advice and presenting with marked compressive cervical myelopathy. She underwent successful surgical decompression with gradual recovery of spastic limb weakness and recovery of sensation. Authors also highlights the importance of early resuscitation and adequate maintainace of mean arterial pressure following acute spinal cord injury. Pertinent literature is briefly reviewed.

Published: July 2017

The article dwells on professional development of public school teachers as an inevitable constituent of education systems in the 21st century. In such economically developed countries as Great Britain, Canada and the USA, the problem of preparing teachers to a difficult and responsible task of upbringing and educating future citizens always remains topical. The authors define the following aim and objectives of their research: to conduct analysis of scientific and pedagogical literature and to define the notion of teachers′ “professional development”; to research a place and role of the constructivist approach to professional development of teachers. Some aspects of the problem under research have been studied by foreign and domestic scientists: political, social, cultural and economic aspects of teachers′ professional development (L. Darling-Hammond, M. Tight); elaboration of professional development curricula (C. Pratt); content of teachers′ professional development (N. Dana Fichtman, S. Zepeda); concept-oriented instruction (J. Guthrie); continuing professional development (Ya. Belmaz, A. Kuzminskyi, O. Kuznietsova). The research methodology comprises theoretical (logical, structural and systematic methods, induction and deduction, comparison and compatibility, analysis and synthesis) and applied (observations, questioning and interviewing) methods. The research results have been presented.

Authors: Kulma M. , Bubová T. , Kopecký O. , Rettich F.
Published: July 2017

This study evaluated the repellent effect of three essential oils against females of Ixodes ricinus, which is considered to be the main arthropod disease vector in Europe. The essential oils could be regarded as user- and environment-friendly alternatives to synthetic repellents. As a comparison sample, the most widely used synthetic repellent DEET was used. All the tested oils exhibited moderate to high initial repellency of 65-85% 5 min after application. The testing was terminated after 80 min, when lavender and eucalyptus repelled 45% and 15% of ticks, respectively. No effect of orange oil was observed after a 20-min mark. The effect of DEET was found to be high and stable (95-100%) throughout the experiment. This study thus revealed that the investigated oils are not as effective as DEET. On the other hand, especially lavender showed an interesting potential as an alternative repellent for outdoor activities of shorter duration.
Slovak Shakespeare in American Exile
Authors: Marcinčin Matúš
Published: July 2017

Ján Vilikovský’s synthesizing monograph Shakespeare u nás (2014) is a great study; however, it does not include the whole history of translations of Shakespeare’s dramas into the Slovak language. Slovak literary and theatre studies have not reflected this theme in relation to Slovak cultural exile after the year 1945. In the present contribution, the author completes the mentioned monograph by Vilikovský, he adds and deals especially with translations written in exile by Andrej Žarnov and Karol Strmeň. He pays special attention to the fragments of translations of Shakespeare’s dramas found as a manuscript in the inheritance left after the tragic death of their author Karol Strmeň. The author reconstructs the fragments and then analyses and compares them with relevant Slovak and Czech translations of Shakespeare’s works. As a result of this study, it can be concluded that the translations by Strmeň written in a modern, cultivated, although slightly archaic Slovak language would have achieved an important position in the history of Slovak translations of Shakespeare’s drama if they had been published.
Ján Zavarský’s Opera Scenographies
Authors: Hrdinová Radmila
Published: July 2017

The present study aims to describe the work that Ján Zavarský, one of the most prominent contemporary Slovak scenographers, has done for musical theatre, mainly opera. The author draws on her years of experience as an audience member, production recordings, photographs, scene designs, and other documentation. Her study is the first attempt at mapping the language of expression that Zavarský has created in two decades, especially in cooperation with the directors Martin Otava and Karla Štaubertová. First, the author deals with the process of creation of a scenographic proposal in dialogue with a director, which gives rise to a scenographic and directorial concept of a production. It then proceeds to identifying the characteristic features of Zavarský’s approach to opera scenography, which include the architectural concept of the scene, simplicity of expression, formal and colour stylization, and the connection between scenography and the movement of characters on the stage. The study includes a list of Zavarský’s scenographies and photographs documenting the individual features of his work for musical theatre in approximately ten productions.
