A critical look at the portfolio as a tool for teacher cognition at pre-gradual level: perceptions of students
Authors: Straková Zuzana
Published: November 2016

Trainees in teacher training programmes experience a variety of courses focusing on helping them to master the basic skills as future language teachers. The most important issue in the entire training is the appropriate balance between the input they receive from the trainer and the hands-on experience in which they learn through experience. One of the best hands-on activities during teacher training is indisputably teaching practice, i.e. real experience of trainees in the school context. Teaching practice offers to trainees first experience with teaching English lessons with holding responsibility for planning, carrying out the lessons as well as learning from this experience, maintaining a good rapport with students and many other aspects. Since trainees work in the external setting without the presence of their Methodology course trainers, it is often a custom to ask trainees to keep a portfolio with lesson plans or material they used during teaching as well as some reflections on the first teaching experience, so that the trainers could create a picture of how their trainees succeeded “out there”. Such a portfolio serves as a useful tool not only for the trainee since the portfolio offers a record of how they managed to carry out specific duty at a specific time; portfolio of this type can provide the trainer with a plastic picture of how trainee managed to apply what they had learned in their Methodology courses. There are many elements which can be included in the teaching practice portfolio such as lesson plans, reflections, various case studies, textbook evaluations, sample teaching aids prepared by the trainee, etc. However, the biggest benefit that portfolio provides the trainee with is the reflection itself – thinking about how successfully something has been mastered and thinking about how things could be done better. EPOSTL (European Portfolio for Student Teachers of Languages) where trainees focus on self-evaluation of their own teaching skills is one of the tools that can help to focus the trainee on specific skill the teacher needs to master. This article tries to answer the question whether trainees are aware of the beneficial effects of such reflection, whether they perceive a tool like the EPOSTL as something that can help them to develop or they consider it rather a duty to be carried out as a part of training. Based on the experience with a group of trainees who used EPOSTL during their teaching practice this case study analyses possible strengths and weaknesses of including such a complex material as EPOSTL in pre-service teacher training.
Comparative exploration of learning styles and teaching techniques between Thai and Vietnamese EFL students and instructors
Authors: Supalak Nakhornsri
Published: November 2016

Learning styles have been a particular focus of a number of researchers over the past decades. Findings from various studies researching into how students learn highlight significant relationships between learners’ styles of learning and their language learning processes and achievement. This research focuses on a comparative analysis of the preferences of English learning styles and teaching techniques perceived by students from Thailand and Vietnam, and the teaching styles and techniques practiced by their instructors. The purposes were 1) to investigate the learning styles and teaching techniques students from both countries preferred, 2) to investigate the compatibility of the teaching styles and techniques practiced by instructors and those preferred by the students, 3) to specify the learning styles and teaching techniques students with high level of English proficiency preferred, and 4) to investigate the similarities of Thai and Vietnamese students’ preferences for learning styles and teaching techniques. The sample consisted of two main groups: 1) undergraduate students from King Mongkut’s University of Technology North Bangkok (KMUTNB), Thailand and Thai Nguyen University (TNU), Vietnam and 2) English instructors from both institutions. The instruments employed comprised the Students’ Preferred English Learning Style and Teaching Technique Questionnaire and the Teachers’ Practiced English Teaching Style and Technique Questionnaire. The collected data were analyzed using arithmetic means and standard deviation. The findings can contribute to the curriculum development and assist teachers to teach outside their comfort level to match the students’ preferred learning styles. In addition, the findings could better promote the courses provided for students. By understanding the learning style make-up of the students enrolled in the courses, faculty can adjust their modes of content delivery to match student preferences and maximize student learning. Finally, this research could establish better understanding between language learning natures of people from Thailand and Vietnam.
TEFL teachers’ and non-TEFL teachers’ perceptions on the relationship between SLA research and language pedagogy
Authors: Zand-Moghadam Amir , Meihami Hussein
Published: November 2016

This study explores TEFL teachers’ and non-TEFL teachers’ perceptions about the relationship between second language acquisition (SLA) research and language pedagogy with regard to familiarity, involvement, accessibility, consultation, relevance, and usefulness of SLA research in L2 pedagogy. To this end, 83 teachers, 40 TEFL teachers and 43 non-TEFL teachers, participated in this study. They filled out a questionnaire addressing their perceptions about SLA research and language pedagogy. The results revealed that the majority of TEFL teachers involved in doing research, at least as their educational term projects, while mostly no contribution was reported by non-TEFL teachers. In addition, TEFL teachers insisted that L2 teachers need to be involved in SLA research to be successful in their teaching career, while non-TEFL teachers were of the opposite opinion. Moreover, it was revealed that TEFL teachers considered the knowledge gained from research studies relevant and useful to their classroom actions, whereas non-TEFL teachers saw their experience more important for managing their classroom actions. Although both groups had contradictory perceptions of the relationship between SLA research and language pedagogy, they showed some common points in this regard. That is, both groups reported on their difficulty in having access to the research materials; they also expressed their willingness to do research.

Published: November 2016

Background:The aim of this study was to explore oxidative stress status, especially the enzyme myeloperoxidase in children with end-stage renal disease. Also, we investigated possible associations between the atherogenic index of plasma and these parameters.

Methods:Lipid status parameters, oxidative stress status parameters, and myeloperoxidase concentration were measured in the sera of 20 children in the last stage of chronic renal disease (ESRD) and 35 healthy children of matching age and sex. The Atherogenic Index of Plasma (AIP) was calculated according to the appropriate equation.

Results:We did not find any significant differences in myeloperoxidase concentrations between the investigated groups (p=0.394). Oxidative stress parameters were, however, significantly higher in the patient group (p<0.001), as well as the atherogenic index of plasma (p<0.001). Myeloperoxidase concentration and advanced oxidation protein product (AOPP) concentration were independently associated with increased AIP in the patient group (p<0.05).

Conclusions:Changes in AIP in children with ERSD are associated with the oxidative stress status and myeloperoxidase concentration.

The Old Phrygian word for ‘feet’: new readings in the ‘podas’-inscription (G-02)
Authors: Kloekhorst Alwin
Published: November 2016

In this article, new readings are proposed for the Old Phrygian inscription G-02, which is famous for having been written next to a depiction of two feet, and for containing the sequence podas, which is commonly interpreted as denoting ‘feet’ and reflecting Proto-Indo-European *pod-/ped-. A careful examination of the damaged part of this inscription reveals the presence of a word petes, however, which is argued to be a better candidate for representing the Old Phrygian word for ‘feet’. Not only does this interpretation yield a better understanding of the composition of the inscription as a whole, it is also in accordance with the so-called Phrygian “Lautverschiebung”, which states that PIE mediae have become voiceless stops in Phrygian.

Rethinking Law and Development in Colombia: How a Dynamic Approach Could Overcome the Chasm Between Law and Ideas of Economic Development
Authors: Alviar García Helena
Published: November 2016

The article explores the different ways in which the relationship between law and development has been thought of by policy makers and academics in Colombia. It proposes that there are two prevalent ways of understanding this relationship, either interpreting law as marginal to the economic development endeavor or central to trigger it. Furthermore, it argues that these two prevalent interpretations have underestimated the complex ways in which law functions. In order to illustrate the complexity of the interaction between law and development, the article then presents the different ways in which property is legally defined in the Colombian context. These definitions range from the classical liberal included in the Civil Code to the Social and Ecological function enshrined in the Constitution.

Published: November 2016

This study investigated the effect of three intramuscular injections of Prostaglandin F2α (PGF2α) administered seven days apart on estrus responses and some reproductive hormonal profiles in post-pubertal gilts.Sixteen gilts were divided into groups A, B, C, and D, with four animals in each group. Group A, B and C gilts were treated with PGF2α injections intramuscularly at doses 5mg,7.5mg and 10mg per gilt respectively on Days 0, 6 and 13 of the experiment. Group D (Control) were treated with intramuscular injections of 2ml phosphate-buffered saline (PBS) instead. Serum samples were collected every 24 hours for four days after each PGF2α injection and estrus detection was conducted daily. Results showed that 100% of Group A came into estrus 96 hours after the second PGF2α injection,while 50% of Group B came into estrus after the first injection; with the other 50% exhibiting estrus following the 2nd injection. Only 50% of Group C displayed estrus signs and this was observed following the second PGF2α injection. Control gilts did not express behavioral estrus during this study, suggesting that PGF2α may have induced estrus in the treated animals. LH and estradiol concentrations were significantly different in Group A and B when compared to the control following the 2nd PGF2α injection. In all, it was observed that serum concentrations of LH, FSH and oestradiol-17β reached maximal levels just prior to expression of estrus, thus suggesting that the pattern of reproductive hormonal changes in PGF2α-synchronized gilts may be quite similar to those of naturally cycling in-estrus gilts.
Distance matters. Assessing socioeconomic impacts of the Dukovany nuclear power plant in the Czech Republic: Local perceptions and statistical evidence
Authors: Frantál Bohumil , Malý Jiří , Ouředníček Martin , Nemeškal Jiří
Published: November 2016

The effect of geographical distance on the extent of socioeconomic impacts of the Dukovany nuclear power plant in the Czech Republic is assessed by combining two different research approaches. First, we survey how people living in municipalities in the vicinity of the power plant perceive impacts on their personal quality of life. Second, we explore the effects of the power plant on regional development by analysing long-term statistical data about the unemployment rate, the share of workers in the energy sector and overall job opportunities in the respective municipalities. The results indicate that the power plant has had significant positive impacts on surrounding communities both as perceived by residents and as evidenced by the statistical data. The level of impacts is, however, significantly influenced by the spatial and social distances of communities and individuals from the power plant. The perception of positive impacts correlates with geographical proximity to the power plant, while the hypothetical distance where positive effects on the quality of life are no longer perceived was estimated at about 15 km. Positive effects are also more likely to be reported by highly educated, young and middle-aged and economically active persons, whose work is connected to the power plant.
Teenage overweight and obesity: A pilot study of obesogenic and obesoprotective environments in the Czech Republic
Authors: Spilková Jana
Published: November 2016

Child overweight and obesity represent a serious health problem worldwide. The Czech Republic now ranks the fourth most obese country in Europe and obesity and overweight is becoming more and more frequent in children and teenagers. This pilot study estimates the prevalence of obesity and overweight among Czech teenagers aged 14–15 years in terms of neighbourhood characteristics, and assesses the effects of neighbourhood environmental quality versus family or personal-level factors on teenage obesity and overweight. The results show that unsafe environments result in the risk of lesser physical activity of their inhabitants, but since the vast majority (92%) of the students felt safe in their neighbourhoods, mediation through safety of the neighbourhood is not at stake. Second, the housing estates demonstrate the most severe problems with both obesity and overweight and their built environments, but when perceptions of sporting facilities and similar opportunities for physical activity are factored in, they do not have low scores; therefore, mediation by physical activity is not a relevant response to the obesity problem. These findings imply that the most important obesogenic and obesoprotective factors are likely to be found within the family environment and personal life styles.
Comparison of factorsinfluencing the Internationalisation Process in France and Poland
Authors: Laskowska Agnieszka
Published: November 2016

The aim of this article is to reveal crucial factors (political, administrative and financial) that influence the attitudes of local governments in the internationalisation process. The paper’s conclusions are based on a study referring to various types of analyses, both quantitative and qualitative, of official documents, databases as well as in-depth interviews. The study was conducted in Lublin, Poland and Nancy in France.

The research shows that the local governments’ attitudes towards international cooperation depend greatly on political factors. In both cases (Lublin and Nancy), despite the differences in political and administrative systems; the nature, activity and range of the existing cooperation is governed much more by the mayor’s ability, his/her individual attitude and approach than by the city’s councillors.
Effects of surface modification and ultrasonic agitation on the properties of PHBV/ZnO nanocomposites
Authors: Bekat Tugce , Öner Mualla
Published: November 2016

Zinc oxide (ZnO) particles were synthesized from aqueous solution by chemical precipitation method. Self-aggregated rod-shaped particles were obtained. Silane modification and ultrasonic dispersion were compared in terms of effectiveness on particle deagglomeration. Complete deagglomeration was achieved with ultrasonic dispersion for untreated particles. Surface-treated and/or ultrasound-applied ZnO particles were incorporated into PHBV matrix by melt-extrusion. Good particle dispersion was achieved in the composites regardless of the agglomeration observed in particles prior to polymer matrix inclusion. Number of regular, rod-shaped particles observed was higher in the composites produced with ultrasound-dispersed particles. ZnO crystals did not affect the melting and crystallization temperatures of PHBV composites, but the degree of crystallinity was decreased. Thermal degradation temperature of PHBV was slightly decreased with ZnO addition. Tensile strength, elongation at break, and toughness of PHBV were affected positively when ultrasound-dispersed (treated or untreated) particles were incorporated into PHBV matrix; whereas application of both ultrasound and silane treatment produced better results.
Virgil and the Water of Nola in the Renaissance
Authors: Miletti Lorenzo
Published: November 2016

The article focuses on the Renaissance debate about an anecdote reported by Gellius, Noctes Atticae 6.20, according to which Virgil erased the name of the city of Nola, in Campania, from Georgics 2.225, since the Nolans did not allow him to run some public water into a farm belonging to him. This essay offers an outline of how and where, between the fifteenth and sixteenth centuries, the debate pro or contra Gellius developed. The epicentre of this debate was the Kingdom of Naples, since Gellius’ anecdote cast a shadow over Nola, which in the Renaissance period was a prosperous centre and wished to appear as the authentic descendant of the glorious ancient town that, according to Livy and Silius, was loyal to Rome during the Punic Wars. The citizens of Nola were concerned that Gellius’ words could be used to create an image of the city as one hostile to the most celebrated poet in antiquity, and thus damage its public reputation. Some voices emerged in defence of Nola while others argued against it. Whether as defenders or accusers, a number of the leading humanists of the Kingdom became involved in this querelle, namely Giovanni Pontano, Jacopo Sannazaro, and Ambrogio Leone, through whom the debate also reached the Netherlands, and Erasmus of Rotterdam.
Eros’ Paedeutic Function in theEphesiacaof Xenophon of Ephesus
Authors: Papadimitropoulos Loukas
Published: November 2016

The primary motivating force of theEphesiaca’s plot can be attributed to the divine factor, which functions in a complementary and inclusive way with the intentions that inform the attitude of the various human agents. Eros’ initial scheme to avenge himself on Habrocomes’ pride constitutes the core of the composite divine intervention that both causes the primary couple’s wanderings and tribulations and brings about the happy denouement. Eros’ revenge centers on the hero’s body, which had been emphatically presented at the beginning of the narration as one of the main reasons for his arrogance towards the god, but ultimately aims at the rehabilitation of the hero, fulfilling thus the hopes of the Ephesians that someday Habrocomes will evolve into a noteworthy citizen. To this end, the purpose of Habrocomes’ wanderings and adventures also involves the acquisition through his several acquaintances of the necessary means that will ensure his future prosperity: in Hippothous the male protagonist will probably find a valuable ally for his subsequent political career in his native city, while the example of Aigialeus ensures the stability of the primary couple’s emotional bond. Furthermore, Habrocomes’ status is raised by the devotion of Anthia and the loyalty of his former servants. Finally, it is not inconceivable that Xenophon has been influenced by the philosophy of Heraclitus.
Women’s Playthings: The Meaning of δούλευμα in Soph.Ant. 756, Eur.Ion748, and Eur.Or.221
Authors: Fisher Roger S.
Published: November 2016

The word δούλευμα, which appears only three times in extant Greek literature, is defined in all the authoritative dictionaries with the meaning of “slave” or “servitude”, but this lexical meaning is not well supported by the contexts in which the word appears. The word δούλευμα does not signify a person’s status as a slave or the duty of a slave to perform a service for its owner. Rather, δούλευμα has an extended or secondary meaning of a woman’s “baby doll” or “doll-like object” (in the same way that other polysemous words, such as κόρη, νύμφη, and γλήνη, can also mean “doll”, depending on the contexts in which these words are used). This proposed definition offers a new perspective on the three scenes in which the word appears in Greek tragedy.

Authors: Shvab R. , Hryha E. , Tahir A. M. , Nyborg L.
Published: November 2016

The state of the powder surface represents one of the main interests in the whole cycle of components’ production using powder metallurgy (PM) route. Large specific surface area of the powder in combination with often alloying with oxygen sensitive elements results in oxidation of the powder surface in most of the cases. The information about surface chemistry of the powder is of vital importance for further consolidation and sintering steps. Surface sensitive analytical techniques – X-ray photoelectron spectroscopy (XPS) and high-resolution scanning electron microscopy combined with energy dispersive X-ray analysis (HR SEM+EDX) were used for surface chemical analysis of the 60Cu-40Sn bronze powder. Determination of the compositional profiles and estimation of the surface oxide layer thickness was done by altering of ion etching and XPS analysis. The results showed tin oxide enrichment and presence of copper hydroxide on the surface of the powder particles. The impurities of P, Zn and Ca were also detected on the top surface of the powder in trace amounts.
The Effect of Transient Liquid Phase on the Joining Process of Aluminum Foam Core Sandwiches
Authors: Tabrizi A. T. , Azadbeh M.
Published: November 2016

Despite recent developments in sandwich panels production technology, there are some difficulties in joining core sandwiches. Liquid Phase Sintering is a conventional method to increase the density of powder metallurgy parts. In this paper, we applied LPS as a joining process between Al-foam and Al-metal by using Al-mixture powders with different compositions as the interlayer. At first stage, Al-Zn powder mixture was used and the possibility of this process was investigated. At later stages, we tried to increase the joint bonding strength with different Al-mixture powder compositions. 3-point bending test was applied and by using mathematical relations, bonding strengths were calculated. The highest bonding strength was obtained, about 9 kPa, when Al-Zn-Mg was used as the interlayer. Also energy dispersive spectrometry (EDS) was used to investigate the diffusion of additive elemental powders to Al-mixture powders.
Politeness in Hittite state correspondence: Address and self-presentation
Authors: Cajnko Mojca
Published: November 2016

In this paper deferential and strategic or face-based politeness are distinguished (Jucker 2010). The distinction seems to be crucial for a proper understanding of the use of address and self-presentation terms and the address formula in Hittite state correspondence. Namely, the corpus of 80 letters written between c. 1450 and 1190 B.C. shows that the appropriate use of politeness largely reflects the writer’s awareness of his place in society, as well as his desire to behave in conformity with culturally expected forms of behavior. Examples of deferential politeness are thus influenced by the relative and absolute social status of communication participants as well as general and socially expected concern for the addressee’s face. Examples of real strategic politeness may be observed in symmetric relations where the writer is trying to minimalize a potentially face-threatening act and in some letters to the Hittite king.
Separation of no-carrier-added 203Pb, a surrogate radioisotope, from proton irradiated natTl2CO3 target using calcium alginate hydrogel beads
Authors: Sarkar Kangkana , Lahiri Susanta , Sen Kamalika
Published: November 2016

203Pb is a promising radioisotope in the field of medical science as an imaging surrogate of 212Pb. In the present investigation 203Pb was produced by proton irradiation of natural Tl2CO3 target and was separated from the bulk Tl target using calcium alginate (CA) hydrogel beads with a high separation factor (3.8×104 at 10−3 M HNO3). During the separation process 203Pb was encapsulated in CA beads and desorption of the radioisotope could only be achieved in 1M HNO3. Possibility of Tl uptake was also checked in Fe doped CA (Fe-CA) beads after oxidation of Tl(I) to Tl(III) by sodium bismuthate. No significant uptake of Tl(III) was noticed in the Fe-CA beads. The matrix is therefore suitable for isolation of 203Pb from the target as well as its storage in the bead for therapeutic as well as diagnostic purpose.
The technique of dermoplasty to treat recurrent nasal polyps: preoperative evaluation, surgical details, postoperative endoscopic appearance and histopathologic analysis
Authors: Anastasopoulos George , Vicheva Dilyana , Tsiompanou Eleni-Christina , Ferekidis Eleftherios
Published: November 2016

BACKGROUND. The tendency of the nasal polyps for recurrence is well established and recognized. A potentially effective measure to reduce this tendency seems to be the replacement of the mucosa responsible for polyp growth.

MATERIAL AND METHODS. Since February 2012, we have used this method in fifteen patients with intractable polyposis. After a short course of preoperative medication, we performed a detailed computed scan analysis to study the anatomy of the ethmoidal complex and calculate the area and contour of the graft. Under general anaesthesia, we removed the mucosa of the nasal roof and replaced it with a split-thickness skin graft. For maintenance, only a short course of nasal drops every three months seems to suffice.

RESULTS. Excluding the first two cases due to a poor surgical technique, the rest of the cases may be considered successful. All patients experience a functional nose with restored nasal breathing and occasionally olfactory function with only a minimal pharmaceutical aid. Polyps still grow, but they show a much more benign course and are readily responsive to medical treatment. Interestingly, polyps present squamous metaplasia postoperatively. This feature needs further investigation.

CONCLUSION. The method of dermoplasty presents a high potential for control of polyp growth. With only an hour prolongation of surgical time, a minor increase in complication rate and a small increase in morbidity rate, the technique deserves further attention from the rhinological society.

Geostatistical analysis of space variation in underground water various quality parameters in Kłodzko water intake area (SW part of Poland)
Authors: Namysłowska-Wilczyńska Barbara
Published: November 2016

This paper presents selected results of research connected with the development of a (3D) geostatistical hydrogeochemical model of the Kłodzko Drainage Basin, dedicated to the spatial variation in the different quality parameters of underground water in the water intake area (SW part of Poland). The research covers the period 2011-2012. Spatial analyses of the variation in various quality parameters, i.e., contents of: iron, manganese, ammonium ion, nitrate ion, phosphate ion, total organic carbon, pH redox potential and temperature, were carried out on the basis of the chemical determinations of the quality parameters of underground water samples taken from the wells in the water intake area. Spatial variation in the parameters was analyzed on the basis of data obtained (November 2011) from tests of water taken from 14 existing wells with a depth ranging from 9.5 to 38.0 m b.g.l. The latest data (January 2012) were obtained (gained) from 3 new piezometers, made in other locations in the relevant area. A depth of these piezometers amounts to 9-10 m.

Data derived from 14 wells (2011) and 14 wells + 3 piezometers (2012) were subjected to spatial analyses using geostatistical methods. The evaluation of basic statistics of the quality parameters, including their histograms of distributions, scatter diagrams and correlation coefficient values r were presented. The directional semivariogram function γ(h) and the ordinary (block) kriging procedure were used to build the 3D geostatistical model. The geostatistical parameters of the theoretical models of directional semivariograms of the water quality parameters under study, calculated along the wells depth (taking into account the terrain elevation), were used in the ordinary (block) kriging estimation.

The obtained results of estimation, i.e., block diagrams allowed us to determine the levels of increased values of estimated averages Z* of underground water quality parameters.
Selected aspects of designing deep excavations
Authors: Obrzud Rafał F. , Hartmann Sébastien , Podleś Krzysztof
Published: November 2016

This paper analyzes two approaches to serviceability limit state (SLS) verification for the deep excavation boundary value problem. The verification is carried out by means of the finite element (FE) method with the aid of the commercial program ZSoil v2014. In numerical simulations, deep excavation in non-cohesive soil is supported with a diaphragm wall. In the first approach, the diaphragm wall is modeled with the Hookean material assuming reduced average stiffness and possible concrete cracking. The second approach is divided into two stages. In the first stage, the wall is modeled by defining its stiffness with the highest nominal Young’s modulus. The modulus makes it possible to find design bending moments which are used to compute the minimal design cross-section reinforcement for the retaining structure. The computed reinforcement is then used in a non-linear structural analysis which is viewed as the “actual” SLS verification.

In the second part, the paper examines the same boundary value problem assuming that the excavation takes place in quasi-impermeable cohesive soils, which are modeled with the Hardening Soil model. This example demonstrates the consequences of applying the steady-state type analysis for an intrinsically time-dependent problem. The results of this analysis are compared to the results from the consolidation-type analysis, which are considered as a reference. For both analysis types, the two-phase formulation for partially- saturated medium, after Aubry and Ozanam, is used to describe the interaction between the soil skeleton and pore water pressure.
Re-Evaluation of Morphological Characters Questions Current Views of Pinniped Origins
Authors: Koretsky I. A. , Barnes L. G. , Rahmat S. J.
Published: November 2016

The origin of pinnipeds has been a contentious issue, with opposite sides debating monophyly or diphyly. This review uses evidence from the fossil record, combined with comparative morphology, molecular and cytogenetic investigations to evaluate the evolutionary history and phylogenetic relationships of living and fossil otarioid and phocoid pinnipeds. Molecular investigations support a monophyletic origin of pinnipeds, but disregard vital morphological data. Likewise, morphological studies support diphyly, but overlook molecular analyses. This review will demonstrate that a monophyletic origin of pinnipeds should not be completely accepted, as is the current ideology, and a diphyletic origin remains viable due to morphological and paleobiological analyses. Critical examination of certain characters, used by supporters of pinniped monophyly, reveals different polarities, variability, or simply convergence. The paleontological record and our morphological analysis of important characters supports a diphyletic origin of pinnipeds, with otarioids likely arising in the North Pacific from large, bear-like animals and phocids arising in the North Atlantic from smaller, otter-like ancestors. Although members of both groups are known by Late Oligocene time, each developed and invaded the aquatic environment separately from their much earlier, common arctoid ancestor. Therefore, we treat the superfamily Otarioidea as being monophyletic, including the families Enaliarctidae, Otariidae (fur seals/sea lions), Desmatophocidae, and Odobenidae (walruses and extinct relatives), and the superfamily Phocoidea as monophyletic, including only the family Phocidae, with four subfamilies (Devinophocinae, Phocinae, Monachinae, and Cystophorinae).
Electron Paramagnetic Resonance and DFT Analysis of the Effects of Bulky Perfluoroalkyl Substituents on a Vanadyl Perfluoro Phthalocyanine
Authors: Moons Hans , Patel Hemantbhai H. , Gorun Sergiu M. , Doorslaer Sabine Van
Published: November 2016

F64PcVO, the vanadyl complex of the perfluoro-isopropyl-substituted perfluorophthalocyanine ligand F64PcH2, exhibits interesting electronic properties compared to related vanadyl phthalocyanine complexes. X- and W-band continuous-wave electron paramagnetic resonance (CW EPR) of undiluted F64PcVO powders illustrate the absence of π-π stacking in these materials due to the bulky substituents. Furthermore, pulsed EPR and electron nuclear double resonance (ENDOR) experiments in combination with density functional theory (DFT) computations were used to determine the principal g values and the 51V, 14N, 1H and 19F hyperfine couplings of a frozen ethanol solution of F64PcVO. The axial ligation of ethanol to vanadium was proven. Axial accessibility of the vanadyl center combined with the high solubility of the complex in different solvents make F64PcVO an interesting molecule for catalytic applications.
Concept of Phase Cycling in Pulsed Magnetic Resonance Using Sinusoidal Magnetic Field Modulation
Authors: Tseytlin Mark
Published: November 2016

In conventional pulsed magnetic resonance suppression of unwanted signals is achieved by changing pulse phases with respect to the reference signal and spin magnetization phase. This method is called phase cycling. An alternative approach is suggested to separate the unwanted signals from the spin echo by using magnetic field modulation. Precession frequency of the spins, and therefore phases of free indication decays and echo signals, can be controlled by the selection of modulation parameters. This enables phase cycling. Since the signal is detected in the presence of the changing magnetic field, which drives spin precession, the echo signal is frequency-modulated. Numerical transformation into an accelerating reference frame associated with the Larmor frequency restores the signal to a form that would have been observed in the absence of modulation. The suggested phase cycling method is analyzed in detail for the two pulse spin echo case.

Aquellas que se presentan asociadas a un tallo flojo (B2) o a un déficit de capital óseo (B3), deben ser tratadas con la revisión femoral.

Materiales y Método: Se estudiaron retrospectivamente 38 pacientes con fracturas periprotésicas de fémur B2 y B3 tratadas con tallos no cementados de fijación distal sin injerto óseo ni placas de osteosíntesis. El tiempo de seguimiento promedio fue de 2.5 años (rango, 1.5 a10).

Resultados: El puntaje promedio alcanzado en el HHS fue de 69 puntos (rango, 57-91).

En todos los casos (100%) se logró la consolidación ósea. La sobrevida libre de revisión fue del 94.8%.

Las complicaciones fueron; 1 (2.6%) hundimiento del tallo mayor a 5mm, 1 (2.6%) luxación, 2 (5.2%) infecciones , 1 (2.6%) hematoma de la herida.

Conclusiones: La técnica de revisión con tallos no cementados de fijación distal sin el aporte de injerto óseo  ha demostrados ser un método eficaz para el tratamiento de las fracturas periprotésicas de  cadera B2 y B3.

Introducción: El objetivo de este trabajo  fue analizar los resultados funcionales y el rango de movi­miento entre tres grupos de pacientes con ar­troplastia total de rodilla: dos utilizando prótesis de alta flexión y el otro con un diseño convencional.

Materiales y Métodos: 64 pacientes fueron operados con prótesis total de rodilla  Zimmer NexGen®, y 34 pacientes operados con Optetrack ®  de alta flexión. Luego de la exclusión de pacientes;  22 pacientes  (grupo A) fueron tratados con diseño de alta flexión de Zimmer, 21 pacientes (grupo B) tratados con prótesis Zimmer convencional, y 25 pacientes (Grupo C) con artroplastia  Optetrack® PS. La evaluación funcional se realizó con el Knee Society Score, el Western Ontario and McMaster Universities osteoathritis index y la escala analógica visual.

Resultados:  En el posoperatorio, el promedio de flexión máxima del grupo A subió de 99° a 113º, con un aumento promedio de 14º, en el grupo B de 106° a 118º con una ganancia promedio de 12º y en el grupo C de 110° a 111° siendo la ganancia de 1°. Los resultados funcionales evaluados con KSS y el WOMAC presentaron mejorías en los tres grupos.

Conclusión: Las evaluaciones clínicas funcionales son favorables en los tres diseños  evaluados. Este estudio muestra que no hay diferencias significativas en la flexión final lograda, y resultados funcionales entre los dos primeros diseños entre sí, si siendo estos significativamente superiores al diseño del tercer grupo luego de un año de seguimiento.

Guerra justa, hermenêutica política e pluralismo religioso em John Rawls e Claude Geffré
Authors: De Oliveira Nythamar , Gomes Tiago De Fraga
Published: November 2016

Para John Rawls é primordialmente importante para o Direito dos Povos que a justiça seja assegurada pela estabilidade de sociedades liberais e decentes. Uma intervenção militar com fins humanitários ou autodefesa seria uma resposta legítima aos abusos perpetrados pelos grupos ou Estados “fora da lei”, na medida em que fomentam a guerra e o terrorismo, o que poderia ser caracterizada como uma instância de “guerra justa”. A hermenêutica política emerge no espaço de razão pública onde se propõe a conciliação e o acordo entre as doutrinas religiosas e as concepções abrangentes de bem comum, com seus conflitos e incompatibilidades. O liberalismo político busca acomodar tal pluralidade de doutrinas abrangentes razoáveis através do consenso sobreposto. Claude Geffré propõe uma teologia com orientação hermenêutica como uma nova postura política diante do pluralismo hodierno. O enigma da alteridade plural das concepções religiosas manifesta a riqueza espiritual da vivência humana do divino, porém, levanta importantes questionamentos para a convivência social. Rawls e Geffré convergem quanto ao problema hermenêutico da justificação normativa postulada num contexto pluralista de reconhecimento do outro e de tolerância em face às querelas irreconciliáveis.
Leituras filosóficas da laudato si
Authors: Bavaresco Agemir
Published: November 2016

Este artigo apresenta a estrutura do documento do Papa Francisco, demonstrando sua abordagem interdisciplinar articulando a política, a economia, a ecologia, a teologia e a ética. Em primeiro lugar, os cenários do planeta são caracterizados, analisando os níveis ambientais e o debate teológicoepistemológico emergente. Depois disso, a crise ecológica é diagnosticada, tendo suas raízes e causas na tecnologia e no antropocentrismo. Em seguida, torna-se explicita a proposta de uma ecologia integral no qual tudo está relacionado e interligado. Finalmente, considerando o contexto de sociedades plurais e os diagnósticos da crise ambiental, o documento sugere uma ética interdisciplinar para resolver os problemas do planeta.

A felnőtt kötődés korszerű mérési lehetősége: A közvetlen kapcsolatok élményei — kapcsolati struktúrák (ECR-RS) kötődési kérdőív magyar adaptációja párkapcsolatban élő felnőtt személyeknél
Authors: Jantek Gyöngyvér , Vargha András
Published: November 2016

Jelen kutatás célja az ún. ECR-RS (Experiences in Close Relationships — Relationship Structures, Fraley, Heffernan, Vicary és Brumbaugh, 2011) kötődési kérdőív magyar adaptálása, mely számos eddig megoldatlan módszertani problémára ad adekvát választ. Egyrészt alkalmas egy-egy fontos személyhez (apa, anya, pár, barát) fűződő kötődés specifikus vizsgálatára. Másrészt az azonos tételeknek köszönhetően a különböző kötődési személyekkel kapcsolatos elkerülés és szorongás mértéke könnyedén összehasonlíthatóvá válik, hiszen a kérdőív ugyanazokat a dimenziókat méri a 4 fontos személlyel kapcsolatban. Felnőtt, párkapcsolatban élő személyek mintáján (n=336) az ECR-RS jó megbízhatósági mutatókkal rendelkezik. A feltáró faktorelemzés a kötődés kétfaktoros elképzelését támasztja alá (elkerülés és szorongás). A kérdőív validitása megfelelő, a magasabb párkapcsolati elkerülés és szorongás alacsonyabb általános jóllét, párkapcsolati elégedettség és párkapcsolati megküzdési erőforrás értékekkel, valamint magasabb depresszió és párkapcsolati stressz értékekkel jár együtt. Az öt alapvonás csak mérsékelt kapcsolatot mutat a felnőtt kötődéssel. A különböző személyekkel kapcsolatban mért elkerülés és szorongás szintje szignifikáns eltéréseket mutat: a számunkra fontos személyekhez különbözőképpen kötődünk, és ez eltérő módon befolyásolja a jóllétet, illetve a párkapcsolat minőségét. K-központú klaszterelemzés segítségével a két dimenzió figyelembevételével lényegében sikerült azonosítani az ismert négy kötődési típust is.
Az önakadályozás pszichológiája
Authors: Török Lilla , Szabó Zsolt Péter , Boda-Ujlaky Judit
Published: November 2016

Önakadályozásnak nevezzük azt a jelenséget, amikor bizonyos körülmények között adott személyiségváltozókkal jellemezhető egyének fontos teljesítményhelyzetek előtt saját maguk által felállított akadályokkal hátráltatják az eredményességüket. A tanulmány elején pontosan definiáljuk az önakadályozást, elhelyezzük a pszichológiai elméletek, valamint a szociálpszichológiai rokon fogalmak között. Az önakadályozás két formáját elkülönítve, a viselkedéses önakadályozást és a mondott akadályokat részletesen tárgyaljuk. Röviden kitérünk a jelenség hátterében meghúzódó motivációkra. A tanulmány elemzi az önakadályozást befolyásoló tényezőket, amelyeket két dimenzió — személyhez vagy környezethez köthető, serkenti vagy gátolja — mentén osztályoz. Az önakadályozás következményeit előnyös és hátrányos megosztásban csoportosítva vitatjuk meg. Az önakadályozás mérési lehetőségeinél bemutatjuk a kérdőíves és kísérleti módszereket. Az összefoglalás során kitérünk az eddig elvégzett elméleti és empirikus munka értékelésére, a gyakorlati alkalmazás kérdéseire, a magyar vonatkozásokra és a kutatási nehézségekre.

Published: November 2016

Sebagai negara maritim, Indonesia memiliki keragaman hayati yang berlimpah di antaranya berbagai jenis rumput laut atau makroalga, yang lazim disingkat dengan alga. Salah satu substansi kimia dari rumput laut  yang  bermanfaat  adalah karbohidrat  berupa  polisakarida seperti alginat, karagenan, dan agar, sedangkan komponen penting lainnya adalah protein, lemak, dan vitamin yang semuanya merupakan metabolit primer.  Metabolit primer tersebut telah banyak dimanfaatkan untuk bahan baku industri, makanan tambahan, sayuran, dan bahan obat-obatan guna  memenuhi  kebutuhan di dalam negeri dan untuk diekspor. Di samping itu, alga juga merupakan sumber senyawa bioaktif, yang merupakan metabolit sekunder yang memiliki aktivitas  seperti  antibakteri, antitumor, antiinflamasi, dan lain-lain. Pemanfaatan metabolit  primer dari alga telah cukup berkembang namun pemanfaatan metabolit sekundernya hingga saat ini masih terbatas.
