Genetic aspects of barite mineralization related to rocks of the teschenite association in the Silesian Unit, Outer Western Carpathians, Czech Republic
Authors: Jirásek Jakub , Dolníček Zdeněk , Matýsek Dalibor , Urubek Tomáš
Published: April 2017

Barite is a relatively uncommon phase in vein and amygdule mineralizations hosted by igneous rocks of the teschenite association in the Silesian Unit (Western Carpathians). In macroscopically observable sizes, it has been reported from 10 sites situated only in the Czech part of the Silesian Unit. Microscopic barite produced by the hydrothermal alteration of rock matrix and also by the supergene processes is more abundant. We examined four samples of barite by mineralogical and geochemical methods. Electron microprobe analyses proved pure barites with up to 0.038 apfu Sr and without remarkable internal zonation. Fluid inclusion and sulphur isotope data suggests that multiple sources of fluid components have been involved during barite crystallization. Barite contains primary and secondary aqueous all-liquid (L) or less frequent two-phase (L+V) aqueous fluid inclusions with variable salinity (0.4-2.9 wt. % NaCl eq.) and homogenization temperatures between 77 and 152 °C. The higher-salinity fluid endmember was probably Cretaceous seawater and the lower-salinity one was probably diagenetic water derived from surrounding flysch sediments during compaction and thermal alteration of clay minerals. The δ34S values of barite samples range between -1.0 ‰ and +16.4 ‰ CDT suggesting participation of two sources of sulphate, one with a near-zero δ34S values probably derived from wall rocks and another with high δ34S values being most probably sulphate from the Cretaceous seawater. All results underline the role of externally derived fluids during post-magmatic alteration of bodies of rock of the teschenite association.
Constitutionalism and Sovereign Wealth Funds
Authors: Grasso Giorgio
Published: April 2017

The aim of this article is to contextualise the study of Sovereign Wealth Funds within constitutionalism, which is construed as a limit to the exercise of power, whatever its source of inspiration. Sovereign Wealth Funds are investment funds that are owned by a sovereign government (this is the main difference from ordinary private investment funds). These funds are today major players on the global financial market and their role has increased since the start of the financial and economic crisis in 2008. This article analyses the influence of Sovereign Wealth Funds on several categories of constitutional law, such as sovereignty or the protection of fundamental rights, and suggests several remedies to improve the weak accountability and the responsibility of these funds. The final aim of this article is to prove that there can be no power without responsibility, which also applies to the power of the most powerful actors within the globalized world, such as Sovereign Wealth Funds.
The Effect of the Vertical Acceleration on Stability Assessment of Seismically Loaded Earth Dams
Authors: Korzec Aleksandra
Published: April 2017

In the assessment of slope stability, the vertical component of acceleration is commonly neglected. However, signal analyses performed on a large number of acceleration time histories have revealed that the vertical peak ground acceleration can be as high as the horizontal one. In this paper, a method of slope stability analysis regarding the vertical component of acceleration is proposed. It considers a rigid body system affected by the acceleration time histories in both horizontal and vertical directions. In a general case, the strength of the contact between acceleration components is time dependent. Parametric analysis was performed on the basis of cyclic harmonic loading, assuming a safety criterion in the form of permanent displacement. The results, for both harmonic and real acceleration time histories, were compared with the results of the commonly used Newmark’s sliding block approach, which revealed significant differences in permanent displacements calculated by the two methods.
Mechanical Properties of Granular Soils: Triaxial versus Plane Strain Investigations
Authors: Sawicki Andrzej , Sławińska Justyna , Mierczyński Jacek , Smyczyński Marcin
Published: April 2017

The paper compares the pre-failure behavior of granular soils investigated in the classical triaxial apparatus and in the true triaxial apparatus, under plane strain conditions. Both experiments are described within the framework of an incremental model of the pre-failure behavior of sands. The methods of tensor algebra are used to compare theoretical predictions with experimental results. The analysis presented deals with the pre-failure deformations of fully drained sand, as well as with its undrained behavior, including static liquefaction and the specific behavior of an initially dilative soil. Some key questions of soil mechanics are discussed, for instance, whether soil parameters determined from one configuration, such as triaxial conditions, can be applied in other cases.
Calculating Distributed Denial of Service Attack Probability in Bloom-Filter based Information-Centric Networks
Authors: Vassilakis Vassilios G. , Wang Liang , Moscholios Ioannis D. , Logothetis Michael D.
Published: April 2017

Information-Centric Networking (ICN) is an emerging networking technology that has been designed to directly operate on named content/information objects, rather than relying on the knowledge of the content location. According to the ICN principles, a user requests the information object by its name or some other form of object identifier. After that, the ICN system is responsible for finding the particular object and sending it back to the user. Despite a large number of works on ICN in recent years, ICN systems still face security challenges. This is especially true when considering different types of alternative networks, such as the wireless community networks (WCNs). In this work, we explore the applicability of ICN principles in the challenging and unpredictable environments of WCNs. We consider stateless content dissemination using Bloom filters (BFs) and analyze two BF based approaches: the traditional single-stage BF and its generalization, the multi-stage BF. We focus on the security aspects of BF based approaches and in particular on distributed denial of service (DDoS) attacks. Finally, we investigate the attack probability for various system and network parameters, such as the number of hash functions, the BF maximum fill factor, and the number of hops toward the victim node.
Congestion Probabilities in Erlang-Engset Multirate Loss Models under the Multiple Fractional Channel Reservation Policy
Authors: Moscholios Ioannis D.
Published: April 2017

A communication link that accommodates different service-classes whose calls have different bandwidth requirements and compete for the available bandwidth under the Multiple Fractional Channel Reservation (MFCR) policy is considered. The MFCR policy allows the reservation of real number of channels in order to favor high speed calls. Two call arrival processes are studied: i) the Poisson (random) process and ii) the quasi-random process. In the first case, calls come from an infinite number of sources while in the second case calls are generated by a finite number of sources. To determine call blocking probabilities for Poisson arriving calls, recursive formulas are proposed based on reverse transition rates. To determine time and call congestion probabilities for quasi-random arriving calls, recursive formulas are proven based on the fact that the steady state probabilities cannot be described by a product form solution. The accuracy of the new formulas is verified through simulation.
Sub-Sampling in OFDM with Constant Time Signal Recovery
Authors: Petrellis Nikos
Published: April 2017

The sub-sampling method for Orthogonal Frequency Division Multiplexing proposed recently, has been extended in this paper allowing the Analog-to-Digital Converter on the receiver side to operate in low power mode, up to 3/4 of the time. The predictability of the parity patterns generated by the Forward Error Correction encoder of the transmitter, when sparse data are exchanged, is exploited in order to define appropriate Inverse Fast Fourier Transform input symbol arrangements. These symbol arrangements allow the substitution of a number of samples by others that have already been received. Moreover, several operations of the Fast Fourier Transform can be omitted because their result is zero when identical values appear at its input. The advantages of the proposed method are: low power, higher speed and fewer memory resources. Despite other iterative sub-sampling approaches like Compressive Sampling, the proposed method is not iterative and thus it can be implemented with very low complexity hardware. The simulation results show that full input signal recovery or at least a very low Bit Error Rate is achieved in most of the cases that have been tested.

Published: April 2017

Periocular biometrics is a relatively new field of research, and only several publications on this topic can be found in the literature. It can become a promising feature that can be used independently or as a complement to other biometrics. In this work, the recognition rates of periocular biometrics on a single acquisition device and inter-device database is verified and the impact of different image sources on the performance of recognition algorithms is investigated. For this purpose a NearInfrared Light database was collected. The database contains images taken by two acquisition devices. In order to test the periocular biometric trait, three feature extraction methods are chosen: Histograms of Oriented Gradients, Local Binary Patterns and Scale Invariant Feature Transform. The fusion of these methods is also proposed and it is tested on inter-device database. The feasibility of applying periocular recognition as an individual decision module for a biometric system is assessed. Experimental results yield Equal Error Rate of 17.65 for right eye using inter-device database of 640 gallery periocular images for each eye side taken from 32 different individuals (20 images per individual for each eye side). These results are obtained by the optimal weighted sum fusion of the three feature extraction methods.

Asthma and allergic rhinitis are common in childhood. Establishing sensitization to aeroallergens is crucial to effectively prevent exacerbation of these respiratory allergic diseases. The study aimed to evaluate sensitization to the most common aeroallergens in children with asthma and allergic rhinitis.We establishedacorrelation between patients sensitized to indoor, outdoor and simultaneously to both allergens. The study population consisted of 276 patients (168 boys and 108 girls) ages 4 to 16 years with asthma (A) and allergic rhinitis (AR). Skin prick tests were performed with 21 commercial allergen extracts: pollens, mites, epithelia and insects, and molds. We found that 217 patients were sensitized to at least one aeroallergen: 117 patients hadapositive result to mites, 92 to pollens, 72 to epithelia and insects, and 63 - to mold allergens. Dermatophagoides pteronyssinus was the most prevalent aeroallergen. Sensitized only to indoor allergens were 104 patients, 60 - only to outdoor allergens, and 53 were sensitized to both. Mites were the most frequent aeroallergens in children with Aand AR. Lately there has been foundasignificant increase in rates of sensitization to mold allergens, especially to Alternaria alternata. Our study has confirmed the dominant role of indoor allergens in children with respiratory allergic diseases.
The Muses in Mourning: Identity and Classicism in Calvinist Heidelberg
Authors: Tipton Joseph A.
Published: April 2017

This paper explores the attitude of sixteenth-century Protestant reformers towards Renaissance humanism and classical learning by examining an eclogue composed in Doric Greek by the Heidelberg arts professor Simon Stenius. Reading Stenius’ eclogue against his classical models, Theocritus (Idylls 1 and 7) and Homer’s Phaeacian narrative (Odyssey, Bks 5–7), it points out the meaning involved in the way Stenius characterizes the dismissal of the Calvinist faculty from Heidelberg upon the accession of the unsympathetic Ludwig VI. It notes how Stenius uses the pastoral genre to infuse his own work with an air of displacement and how he transposes the image of the shipwrecked Odysseus onto his own exiles in order to imply their loss of identity. When this loss of identity is soon given further definition by the ecphrasis of a rustic cup which inverts the cup described in Theocritus Idyll 1, Stenius’ attitude to classical learning is revealed: The cup not only signifies a silencing of the Muses, but – most importantly – it joins the Muses together with the Heidelberg Protestants in a mutual association of mourning. The sum total is the location of the voice and identity of the Heidelberg Calvinists within the highest registers of classical literature.

Published: April 2017

Introduction: The functions and mechanisms of prion proteins (PrPC) are currently unknown, but most experts believe that deformed or pathogenic prion proteins (PrPSc) originate from PrPC, and that there may be plural main sites for the conversion of normal PrPC into PrPSc. In order to better understand the mechanism of PrPC transformation to PrPSc, the most important step is to determine the replacement or substitution site.

Material and Methods: BALB/c mice were challenged with prion RML strain and from 90 days post-challenge (dpc) mice were sacrificed weekly until all of them had been at 160 dpc. The ultra-structure and pathological changes of the brain of experimental mice were observed and recorded by transmission electron microscopy.

Results: There were a large number of pathogen-like particles aggregated in the myelin sheath of the brain nerves, followed by delamination, hyperplasia, swelling, disintegration, phagocytic vacuolation, and other pathological lesions in the myelin sheath. The aggregated particles did not overflow from the myelin in unstained samples. The phenomenon of particle aggregation persisted all through the disease course, and was the earliest observed pathological change.

Conclusion: It was deduced that the myelin sheath and lipid rafts in brain nerves, including axons and dendrites, were the main sites for the conversion of PrPC to PrPSc, and the PrPSc should be formed directly by the conversion of protein conformation without the involvement of nucleic acids.

Authors: Nunes André Valle , Koroiva Ricardo , Gomes Vanessa Gabrielle Nóbrega , Orsini Vinícius Santana
Published: April 2017

One group ofAteles chamek(Humboldt 1812) was observed during 12 days in the Vila Bela da Santíssima Trindade municipality, in the state of Mato Grosso. During that time fecal samples (n=10) were collected and molecular sequencing was used to confirm species identification. The results suggest that the particular pattern of facial hair color observed in this group may be used for differentiation from other sub-populations; however, a deeper study is required for confirmation of these results. This record represents the most southwestern observation of this species, and increases the geographic distribution ofA. chamekfor about 16 km into the southern Brazilian Amazon. Taking into consideration the threatened status of this species of monkey, and that this region is under constant intensive deforestation, it is important to highlight that ecological studies and conservation activities require urgent development.
Energy Efficiency of a Biofuel Production System
Authors: Wasiak Andrzej , Orynycz Olga
Published: April 2017

Manufacturing engineering is supposed to provide analyses related to various aspects of manufacturing and production in order to maximise technological, energy, and economic gains in relevant production processes. The present paper gives a recapitulation of several publications by present authors, presenting considerations of the energy efficiency of biofuel production. The energy efficiency is understood as the ratio of energy obtained from biofuels produced basing on crops from a particular area to the energy required to satisfy needs of all subsidiary processes assuring correct functioning of the production system, starting from operations aimed to obtain agricultural crops, and ending with the conversion of the crops onto biofuels.

Derived by the present authors, the mathematical model of energy efficiency of biofuel production is extended to a more general form, and applied to the analysis of quantitative relations between energy efficiency of sc. “energy plantations”, and further elements of biofuel production system converting harvested biomass into biofuel. Investigations are aimed towards the determination of the role of biomass as a source of energy.

Cooperative Authoritarians and Regime Stability
Authors: Fuller Clay Robert
Published: April 2017

This article assumes that the post-cold war unipolar global power structure marked the beginnings of a two-level game of national survival involving an international process of “othering,” where the winning democracies and their leaders (the “West”) view many non-democracies and their leaders as threats that they must convert, subjugate, or eradicate. Using new data on special economic zones (SEZs), I find that geographically restricting economic liberalization and reducing competition from opposition parties increases authoritarian stability and durability in this new environment.
Linguistic record of suffering in pain disease (Wallenberg syndrome) in “The Diary without vowels” by Aleksander Wat
Authors: Jaxa-Rożen Hanna
Published: April 2017

The elaboration is rooted in the humanities, it constitutes a so-called case study and it suits the discussion on the significance of psychosocial, biographic and axiological factors in the study of people with disabilities. The Diary by Aleksander Wat, a poet and intellectualist constitutes an extraordinary and the only such mature testimony of suffering written in Polish, a linguistic record of pain in Wallenberg syndrome. Raising awareness and the holistic approach to disability is particularly important if rehabilitation is almost impossible. Apart from physical pain, mental pain is equally significant, and a physiotherapist with their compassion and understanding can significantly alleviate suffering of the patient and their loved ones. In the elaboration significance of the humanistic coefficient is highlighted, the application of which in the rehabilitation interaction protects both sides of the contact from the asymmetry of power relations.

Published: April 2017

Aim. The aim of the study was to investigate parents’ knowledge and attitudes towards compulsory immunization of their children.

Material and methods. The research was conducted with the survey questionnaire among 110 randomly chosen parents aged 18-40 whose infants were inpatients at the University Children’s Hospital in Lublin.

Results. The study revealed that parents were poorly informed about the age of the first vaccination of their infant, compulsory and recommended vaccines, combined vaccines, contraindications for vaccination and adverse reactions following immunization. More than 50% of the parents had a rather positive attitude towards vaccination. However, one fifth admitted that they had seen campaigns which presented immunization of children as harmful. The most popular opinion among the respondents was that compulsory and recommended vaccinations for children should be given only against the most dangerous diseases. The majority of parents considered vaccinations to be safe and only a small percentage of parents were against immunizing their children due to possible health complications. Most of the parents were willing to immunize their children with all the compulsory vaccines and only several recommended ones (as they are not free of charge). Many of them declared they would choose combined vaccines.

Conclusions. Attitudes of parents towards immunization of children varied in the studied group. We concluded that parents were generally poorly informed about immunization of infants. The fact that knowledge about vaccinations may influence parents’ future decisions to protect their children against numerous infectious diseases calls for intensified education on the subject.
Principles for the Safe Moving and Handling of Patients
Authors: Wanless Stephen
Published: April 2017

Human movement when walking or running is a widely researched area. However, there is an increased incidence of musculoskeletal injury from poor positioning when moving and handling patients amongst healthcare professionals and is one of the main causes of long term musculoskeletal health problems. In the clinical area, an individual’s musculoskeletal health system is subjected to mechanical loading, increasing the body’s stress and strain limits, and once these are exceeded injury occurs. The risk of pain and injury has a direct relation from the over use of poor posture from poor moving and handling, which in turn can cause loss of strength and reduce musculoskeletal function. This can be changed through healthcare workers adopting safe biomechanical body movements during patient handling tasks.

Internet advertising and analytics technology companies are increasingly trying to find ways to link behavior across the various devices consumers own. Thiscross-device trackingcan provide a more complete view into a consumer’s behavior and can be valuable for a range of purposes, including ad targeting, research, and conversion attribution. However, consumers may not be aware of how and how often their behavior is tracked across different devices. We designed this study to try to assess what information about cross-device tracking (including data flows and policy disclosures) is observable from the perspective of the end user. Our paper demonstrates how data that is routinely collected and shared online could be used by online third parties to track consumers across devices.

Published: April 2017

This paper is focused on the process of designing the desired plastic component and injection mould by using the 3D CAD systems. The subsequent FEM analysis of the injection mould process was carried out in order to define shrinkage and deformation of the plastic material by CAE system. The dimensions of the mould were then modified to compensate the shrinkage effect. Machining process (milling and the laser texturing) of the mould was performed by using CAM systems. Finally, after the production of the plastic components by the injection mould technology, the inspection of the plastic component dimensions was carried out by CAQ in order to define the accuracy of the whole CAx chain. It was also demonstrated that CAx systems are an integral part of pre-production and production process.

Published: April 2017

Numerically controlled machines require precise control, because it is always necessary to know the placement of the effector. Control involves the use of electric motors that can be checked with precision. Therefore stepper motors are preferred. A further advance in stepper control is to incorporate a reaction mechanism for the rotor (for example, an encoder) so as communication is optimal for generating the torque, depending on the position of the rotor. This turns the motor into a servo mechanism with very high torque and very good position resolution. An advance in this technique is to operate the motor in a closed loop only if the error of rotor positioning becomes too high. This will allow the system to avoid oscillation while searching for a position, a problem that commonly occurs with servos. The supervision of a numerically controlled tool is limited to the control of electric motors that actuate mechanical assemblies. Control can be implemented by using specialized integrated circuits or microcontrollers. This paper presents a numerically controlled (CNC) machine with microcontroller.
Estimation of long memory in volatility using wavelets
Authors: Kraicová Lucie , Baruník Jozef
Published: April 2017

This work studies wavelet-based Whittle estimator of the fractionally integrated exponential generalized autoregressive conditional heteroscedasticity (FIEGARCH) model often used for modeling long memory in volatility of financial assets. The newly proposed estimator approximates the spectral density using wavelet transform, which makes it more robust to certain types of irregularities in data. Based on an extensive Monte Carlo study, both behavior of the proposed estimator and its relative performance with respect to traditional estimators are assessed. In addition, we study properties of the estimators in presence of jumps, which brings interesting discussion. We find that wavelet-based estimator may become an attractive robust and fast alternative to the traditional methods of estimation. In particular, a localized version of our estimator becomes attractive in small samples.
The Difference Between Countermovement and Squat Jump Performances: A Review of Underlying Mechanisms With Practical Applications
Authors: Van Hooren Bas , Zolotarjova Julia
Published: April 2017

Van Hooren, B and Zolotarjova, J. The difference between countermovement and squat jump performances: a review of underlying mechanisms with practical applications. J Strength Cond Res 31(7): 2011–2020, 2017—Two movements that are widely used to monitor athletic performance are the countermovement jump (CMJ) and squat jump (SJ). Countermovement jump performance is almost always better than SJ performance, and the difference in performance is thought to reflect an effective utilization of the stretch-shortening cycle. However, the mechanisms responsible for the performance-enhancing effect of the stretch-shortening cycle are frequently undefined. Uncovering and understanding these mechanisms is essential to make an inference regarding the difference between the jumps. Therefore, we will review the potential mechanisms that explain the better performance in a CMJ as compared with a SJ. It is concluded that the difference in performance may primarily be related to the greater uptake of muscle slack and the buildup of stimulation during the countermovement in a CMJ. Elastic energy may also have a small contribution to an enhanced CMJ performance. Therefore, a larger difference between the jumps is not necessarily a better indicator of high-intensity sports performance. Although a larger difference may reflect the utilization of elastic energy in a small-amplitude CMJ as a result of a well-developed capability to co-activate muscles and quickly build up stimulation, a larger difference may also reflect a poor capability to reduce the degree of muscle slack and build up stimulation in the SJ. Because the capability to reduce the degree of muscle slack and quickly build up stimulation in the SJ may be especially important to high-intensity sports performance, training protocols might concentrate on attaining a smaller difference between the jumps.
Domain Selectivity in the Parahippocampal Gyrus Is Predicted by the Same Structural Connectivity Patterns in Blind and Sighted Individuals
Authors: Wang Xiaoying , He Chenxi , Peelen Marius V. , Zhong Suyu , Gong Gaolang , Caramazza Alfonso , Bi Yanchao
Published: April 2017

Human ventral occipital temporal cortex contains clusters of neurons that show domain-preferring responses during visual perception. Recent studies have reported that some of these clusters show surprisingly similar domain selectivity in congenitally blind participants performing nonvisual tasks. An important open question is whether these functional similarities are driven by similar innate connections in blind and sighted groups. Here we addressed this question focusing on the parahippocampal gyrus (PHG), a region that is selective for large objects and scenes. Based on the assumption that patterns of long-range connectivity shape local computation, we examined whether domain selectivity in PHG is driven by similar structural connectivity patterns in the two populations. Multiple regression models were built to predict the selectivity of PHG voxels for large human-made objects from white matter (WM) connectivity patterns in both groups. These models were then tested using independent data from participants with similar visual experience (two sighted groups) and using data from participants with different visual experience (blind and sighted groups). Strikingly, the WM-based predictions between blind and sighted groups were as successful as predictions between two independent sighted groups. That is, the functional selectivity for large objects of a PHG voxel in a blind participant could be accurately predicted by its WM pattern using the connection-to-function model built from the sighted group data, and vice versa. Regions that significantly predicted PHG selectivity were located in temporal and frontal cortices in both sighted and blind populations. These results show that the large-scale network driving domain selectivity in PHG is independent of vision.

SIGNIFICANCE STATEMENTRecent studies have reported intriguingly similar domain selectivity in sighted and congenitally blind individuals in regions within the ventral visual cortex. To examine whether these similarities originate from similar innate connectional roots, we investigated whether the domain selectivity in one population could be predicted by the structural connectivity pattern of the other. We found that the selectivity for large objects of a PHG voxel in a blind participant could be predicted by its structural connectivity pattern using the connection-to-function model built from the sighted group data, and vice versa. These results reveal that the structural connectivity underlying domain selectivity in the PHG is independent of visual experience, providing evidence for nonvisual representations in this region.

Published: April 2017

Pheochromocytomas (PCCs) and paragangliomas (PGLs) are rare tumours with a heterogeneous genetic background. Up to 40% of apparently sporadic PCC/PGL cases carry 1 of the 12 gene germline mutations conferring genetic susceptibility to PCC/PGL. Although the precise mechanisms are unclear, TMEM127 is one of the rare responsible genes for PCC/PGL. Here we report the case of a patient with familial PCC having a novel TMEM127 variant (c.119C > T, p.S40F). In silico prediction analysis to evaluate the functional significance of this variant suggested that it is a disease-causing variant. A PCC on the left side was considered to be the dominant lesion, and unilateral adrenalectomy was performed. The histopathologic findings were consistent with benign PCC. A loss of heterogeneity of the TMEM127 variant was detected in the surgically removed tumour.

Learning points:

c.119C > T (p.S40F) is a novel TMEM127 variant that can cause pheochromocytoma.

The tumour showed loss of heterozygosity of this TMEM127 variant.

The clinical phenotype of this mutation is putative bilateral pheochromocytoma in the 4th decade.

Unilateral adrenalectomy may be performed as the initial surgery in such cases.
Insulin receptor substrate signaling controls cardiac energy metabolism and heart failure
Authors: Guo Cathy A , Guo Shaodong
Published: April 2017

The heart is an insulin-dependent and energy-consuming organ in which insulin and nutritional signaling integrates to the regulation of cardiac metabolism, growth and survival. Heart failure is highly associated with insulin resistance, and heart failure patients suffer from the cardiac energy deficiency and structural and functional dysfunction. Chronic pathological conditions, such as obesity and type 2 diabetes mellitus, involve various mechanisms in promoting heart failure by remodeling metabolic pathways, modulating cardiac energetics and impairing cardiac contractility. Recent studies demonstrated that insulin receptor substrates 1 and 2 (IRS-1,-2) are major mediators of both insulin and insulin-like growth factor-1 (IGF-1) signaling responsible for myocardial energetics, structure, function and organismal survival. Importantly, the insulin receptor substrates (IRS) play an important role in the activation of the phosphatidylinositide-3-dependent kinase (PI-3K) that controls Akt and Foxo1 signaling cascade, regulating the mitochondrial function, cardiac energy metabolism and the renin–angiotensin system. Dysregulation of this branch in signaling cascades by insulin resistance in the heart through the endocrine system promotes heart failure, providing a novel mechanism for diabetic cardiomyopathy. Therefore, targeting this branch of IRS→PI-3K→Foxo1 signaling cascade and associated pathways may provide a fundamental strategy for the therapeutic and nutritional development in control of metabolic and cardiovascular diseases. In this review, we focus on insulin signaling and resistance in the heart and the role energetics play in cardiac metabolism, structure and function.
DENIAL OF TRANSLATION AND DESIRE TO TRANSLATE
Authors: Gambier Yves
Published: April 2017

Translating and translation are transformed with Information and Communication Technology (ICT). Yesterday, translation was invisible, denied – as a need, as an activity, as a profession, and as a discipline. Within three decades, a new work environment is shaking up the translators’ world. New types of translators are emerging. The balance between supply and demand is changing. However, we still need adequate tools and methods to investigate the new hierarchy which has become established between translators, between different kinds of job markets.
VERTIMO SKURDAS IR SPINDESYS
Authors: Y Gasset Jose Ortega
Published: April 2017

Didžiulis ispanų filosofo Jose Ortegos y Gasseto ( Jose Ortega y Gasset, 1883–1955) intelektinis palikimas aprėpia daugybę sričių – estetiką, filosofiją, istoriosofiją, kultūrologiją, politiką, sociologiją. Žvelgiant iš šiandienos perspektyvos, svarbiausiu jo indėliu į Vakarų Europos minties raidą laikytina garsioji estetinė esė „Meno dehumanizavimas“ („La deshumanizacion del arte“, 1925) ir filosofinė studija „Masių sukilimas“ („La rebelion de las masas“, 1930). Plėtodamas savo filosofines koncepcijas, ilgainiui Ortega y Gassetas atsigręžė į kalbą kaip į svarbiausią filosofinio tyrimo įrankį, o susidūręs su savo darbų vertimais į kitas Europos kalbas (daugiausia į vokiečių), ėmė gilintis į kalbos ir vertimo problemas. Šių apmąstymų rezultatas – vertimui skirta esė „Vertimo skurdas ir spindesys“ („Miseria y esplendor de la traduccion“, 1939 m.). 1940 m. ją pirmą sykį išspausdino leidykla „Coleccion austral“ rinkinyje „Pašaukimų knyga“ („El libro de las misiones“) kartu su kitais dviem Ortegos y Gasseto darbais – „Bibliotekininko pašaukimas“ („Mision del bibliotecario“) ir „Universiteto pašaukimas“ („Mision de la Universidad“). Nuo tada visi trys darbai spausdinami kartu, o pati knyga sulaukė daugybės pakartotinių leidimų.
SOURCE LANGUAGE INTERFERENCE WITH TARGET LANGUAGE IN CONFERENCE INTERPRETING
Authors: Dailidėnaitė Alina , Volynec Julija
Published: April 2017

This article describes an experimental study of lexical interference in simultaneous interpreting from English into Lithuanian and from Lithuanian into English. The paper aims to contribute to the literature on language interference in simultaneous interpreting as well as to identify the influence of lexical interference on directionality and quality of simultaneous interpreting. The experiment was carried out with 6 students working in two directions (from English into Lithuanian and from Lithuanian into English). The paper presents the analysis of the types, frequency and gravity of lexical interference. The results of the study suggest that lexical interference is more common and more detrimental to quality when interpreting into the B language. The results also demonstrate that interpreters experience more difficulties when interpreting word equivalents than phraseological units.
NEVERČIAMI TEKSTAI VERTIME
Authors: Kaminskienė Ligija , Maskaliūnienė Nijolė
Published: April 2017

Straipsnyje pateikiama dviejų tipų neverčiamų tekstų analizė. Pirmiausia aptariami vertimo vienetai – įvairios apimties leksiniai vienetai, sudarantys nedalomą minties vienovę. Jie kilę iš tradicijos ir kultūros ir sudaro šnekos aktų pagrindą. Tekste vertimo vienetai dažnai įgyja oficialų – kanonizuotą, teisinį – statusą. Lygiagretieji tekstai (viešieji įspėjamieji, nurodomieji, draudžiamieji ir kt. ženklai, plakatai ir pan.) – tai skirtingi tekstai, kylantys iš identiškos pragmatinės situacijos. Jie, skirtingai nei vertimo vienetai, pasižymi šiokiu tokiu variantiškumu, tačiau jų vartojimą kalboje lemia kalbos normos, tradicijos, sutartinės vartojimo formos, adresanto ir adresato santykiai.

KOMPIUTERIŲ VIRUSOLOGIJOS TERMINŲ PARADIGMINIAI SEMANTINIAI SANTYK IAI IR ŠALTINIAI
Authors: Maskaliūnienė Nijolė , Paura Markas
Published: April 2017

Lietuviškosios terminografijos istorijoje kompiuterių virusologijos sąvoka ir jos semantinį lauką sudarantys terminai dar netapo tyrimų objektu, nėra ir šių terminų vartosenos tradicijos. Terminografiniuose šaltiniuose, dažniausiai žodynėliuose, virusai paprastai priskiriami kenkimo programoms (angl. malware). Šių terminų apibrėžčių analizė leidžia tiksliau nustatyti jų vietą sistemoje ir paradigminius semantinius santykius. Straipsnyje analizuojami terminai ir vartojama leksika, viena vertus, patvirtina daugelio šios srities terminų atsiradimą vidinio skolinimosi būdu ir sąsajas su tokiomis dalykinėmis sritimis kaip medicina, biologija, teisė, karyba, psichologija ir pan.; kita vertus, atskleidžia termino kompiuterių virusas metaforinę prigimtį – visas jo semantinis laukas personifikuojamas per kolokacijas su veiksmažodžiais ir būdvardžiais.
MEDIOS, DEBATE Y POLÍTICAS SOCIALES: PERCEPCIONES SOBRE LOS OBSTÁCULOS PARA PARTICIPAR
Authors: Betancourt Díaz Elba
Published: April 2017

Ser parte de la discusión pública sobre políticas sociales a través de los medios pudiera ser un desafío para los/as trabajadores y trabajadoras sociales. El reto puede deberse a múltiples factores individuales y estructurales que pudieran minar su potencial para participar en los medios e influenciar la opinión pública a favor de mejores políticas para el bienestar social. No obstante, fundamentándose en los valores de la profesión, y en sus conocimientos y experiencias, pueden ejercer diferentes roles en este debate. Sin embargo, poco se ha explorado su participación en el debate público sobre políticas a través de losmedios. Esta investigación tuvo como objetivo conocer los factores que obstaculizan la participación de los profesionales del trabajo social en el debate público a través de los medios de comunicación en Puerto Rico. Se utilizó un diseño exploratorio con método mixto secuencial, en cuya fase cualitativa, se realizó entrevistas semiestructuradas a profundidad a 12 trabajadores y trabajadoras sociales. Del análisis de discurso, surgieron tres categorías vinculadas a obstáculos asociados con su proceso de socialización, dinámicas de poder al interior de sus trabajos y tensiones en la interacción con los medios. Finalmente, se ofrecen recomendaciones sobre cómo integrarse al debate público a través de los medios.
EL NUEVO CONTEXTO DE LAS CAMPAÑAS ELECTORALES: EL CASO DEL APP MIVOTOHOY
Authors: Carazo Barrantes Carolina
Published: April 2017

Este artículo analiza el caso de una aplicación (MiVotoHoy) propuesta al Tribunal Supremo de Elecciones (TSE) de Costa Rica para la campaña presidencial de febrero 2014 y que el TSE no autorizó. En el artículo se discute el nuevo contexto en el que hoy en día se desarrollan las campañas electorales, uno en el que las encuestas enfrentan cada vez más limitaciones para seguir cumpliendo su función de predicción en periodos electorales; al tiempo que las tecnologías de la información y la comunicación han puesto sobre la palestra temas como la conectividad móvil, el empoderamiento ciudadano y la participación política de jóvenes a través de “apps”, entre otros aspectos.
