RESÚMENES Y COMENTARIOS DE TESIS: La Inteligencia Emocional de docentes universitarios y su implicancia en estudiantes de ciencias experimentales
Authors: Bocco María Inés 
Published: May 2017

El trabajo que se presenta forma parte de una Tesis de la Maestría en Didáctica de las Ciencias Experimentales de la Facultad de Bioquímica y Ciencias Biológicas (FBCB) de la Universidad Nacional del Litoral (UNL).Consiste en el estudio de la relación que existe entre Capacidades de la Inteligencia Emocional (CIE) en docentes universitarios y el desempeño académico de estudiantes del ciclo básico de las carreras de Bioquímica y Licenciatura en Biotecnología de la UNL.El termino Inteligencia Emocional (IE) surge de Salovey y Mayer (1990) y se refiere a la capacidad de reconocer nuestros propios sentimientos y de los demás, y de manejar bien las emociones. Además sostienen que la inteligencia interpersonal es un área de la IE, y la definen como la capacidad para comprender a los demás, entender cómo operan y cómo se debe trabajar cooperativamente.La empatía, que se desprende de la inteligencia interpersonal, es la habilidad que se posee para entender lo que están sintiendo otras personas y ubicarse en situaciones desde su perspectiva. Esta habilidad social favorece el liderazgo, y puede ser usada para persuadir, dirigir, negociar y resolver situaciones que promuevan el trabajo en equipo.

Technology Diffusion and Trade Liberalization
Authors: Beladi Hamid , Oladi Reza 
Published: May 2017

Abstract
We consider a developing economy where multinational corporations compete with foreign and local firms in a monopolistically competitive market. The focus of our paper is on consequences of a policy mix of tariffs and foreign direct investment (FDI) tax in a developing economy. We assume all firms are technologically heterogeneous and that foreign firms are technologically superior to local firms. Central to our model is the assumption that FDI activities by multinational corporations would lead to diffusion of technology in the developing economy. We show the existence of a non-trivial equilibrium where most technologically advanced foreign firms emerge as multinationals, engage in FDI activities and this in turn leads to the diffusion of technology. We also show that trade liberalization without liberalization of foreign investment may lead to the protection of most technological backward local firms in the developing economy and such liberalization can reduce the welfare of a representative consumer.

Published: May 2017

AbstractCalcium sulfate dihydrate (CaSO4·2H2O) was prepared from the chemical reaction between calcium carbonate from duck eggshell and sulfuric acid at 25°C. The CaSO4·2H2O was dried in an oven at 110°C and transformed into calcium sulfate hemihydrate or plaster of Paris (CaSO4·0.5H2O). The CaSO4·0.5H2O was calcined at 700, 800 and 900°C and transformed into anhydrite or anhydrous calcium sulfate (CaSO4). The raw material used in this research was the duck eggshell, the waste eggshell generated from food processing industries. The obtained anhydrous calcium sulfate or anhydrite has true density, color, specific surface area, pore diameter and particle size equal to 2.95 g/cm3, white powder, 3.57 m2/g, 96.98 Å and 3.983 μm, respectively. In addition, other characteristics, microstructures, phase transformation and physical properties of raw materials and calcium sulfates were investigated and reported here using X-ray fluorescencemeter, Fourier transform infrared spectrometer, differential thermal analyzer, thermogravimetric analysis, scanning electron microscope, X-ray diffractometer, pycnometer method and Brunauer-Emmett-Teller.
The Controllable Preparation, Properties and Structural Characteristics of Xylitol/Menthol Co-crystals
Authors: Wang Zhanzhong , Zhang Xiao , Chen Boru , Hou Mengna , Liu Tiankuo 
Published: May 2017

Abstract
Xylitol is fast gaining ground over other sugar substitute owing to its high sweeting and low calorie properties. Menthol, a flavor agent, is widely used in food production. However, menthol can easily sublimate, while xylitol has a strong hygroscopicity. In this study, the co-crystals of xylitol with menthol are performed aiming to improve their negative properties. The results indicated that the water activity of co-crystals varies from 0.126 to 0.370. Meanwhile, the hygroscopicity of co-crystals is reduced to some extent compared with xylitol. Differential scanning calorimetry results demonstrated that co-crystals have similar thermal properties. What’s more, co-crystals have nearly identical X-ray diffraction patterns with xylitol. Thus, it is suggested that the microstructure of co-crystals is influenced mostly by the compound with a high ratio. Overall, this study can convey important idea for the development of food new materials, also the control and application based on co-crystallization techniques in food industry.
“I joined the Party to keep ourselves out of the System.” Neo-Pagan Survival Strategies in Socialist Hungary
Authors: Csáji László Koppány 
Published: May 2017

Abstract
The paper presents a Hungarian Ethno-Pagan group (Bolyanest) which was established in 1979, active in and around Budapest. In the early 80s the group was a forum for New Age-like ideas: Gaia cult, esoteric concepts, natural-based peace-campaigns, yoga, Reiki and other theories about nature, love, humanity, human potentials and peace. The author analyses how this group shifted slowly from the New Age to the Neo-Pagan characteristics during the 80s. The group had a complex survival strategy, which contained several conscious and instinctual responses to the communist system. One of these was the use of espionage: having an informer within the police from among their membership to provide reports that were to benefit the movement. Another strategy was that some members joined the Socialist Party to reassure the communist authorities of their loyalty. The Hungarian society considered communism as a field of parallel realities: one was the communist system‘s narratives, and the other was the society‘s private discourses. Beside these, Bolyanest members created a third reality: the group‘s own value-system and narratives. The cognitive ability to alternate between the realities was also an important key to survival.
Nanomaterials for lithium-ion batteries and hydrogen energy
Authors: Stenina Irina A. , Yaroslavtsev Andrey B. 
Published: May 2017

Abstract
Development of alternative energy sources is one of the main trends of modern energy technology. Lithium-ion batteries and fuel cells are the most important among them. The increase in the energy and power density is the essential aspect which determined their future development. We provide a brief review of the state of developments in the field of nanosize electrode materials and electrolytes for lithium-ion batteries and hydrogen energy. The presence of relatively inexpensive and abundant elements, safety and low volume change during the lithium intercalation/deintercalation processes enables the application of lithium iron phosphate and lithium titanate as electrode materials for lithium-ion batteries. At the same time, they exhibit low ionic and electronic conductivity. To overcome this problem the following main approaches have been applied: use of nanosize materials, including nanocomposites, and heterovalent doping. Their impact in the property change is analyzed and discussed. Hybrid membranes containing inorganic nanoparticles enable a significant progress in the fuel cell development. Different approaches to their preparation, the reasons for ion conductivity and selectivity change, as well as the prospects for their application in low-temperature fuel cells are discussed. This review may provide some useful guidelines for development of advanced materials for lithium ion batteries and fuel cells.
Money supply and inflation dynamics in the Asia-Pacific economies: a time-frequency approach
Authors: Bekiros Stelios , Muzaffar Ahmed T. , Uddin Gazi S. , Vidal-García Javier 
Published: May 2017

Abstract:We examine the relationship between money supply growth and inflation in 3 Asian Economies which are India, Malaysia and Japan using a time-frequency approach. The application of a unified multi-scale analysis allows us to provide a continuous assessment of the link between money supply growth and inflation, unlike most of the existing literature studying this relationship. We also employ a bivariate frequency-domain causality test to determine the nature and direction of interdependence between money supply growth and inflation dynamics. Our findings provide a better understanding of their lead-lag linkages and causal relationship in the selected countries of the Asia-Pacific region.
On the design of a fractal calibration pattern for improved camera calibration
Authors: Schilling Hendrik , Diebold Maximilian , Gutsche Marcel , Jähne Bernd 
Published: May 2017

Abstract
Camera calibration, crucial for computer vision tasks, often relies on planar calibration targets to calibrate the camera parameters. This work describes the design of a planar, fractal, self-identifying calibration pattern, which provides a high density of calibration points for a large range of magnification factors. An evaluation on ground truth data shows that the target provides very high accuracy over a wide range of conditions.
One-pot desilylation-Sonogashira coupling
Authors: Horstmann Jan , Reger Stefanie , Neumann Beate , Stammler Hans-Georg , Mitzel Norbert W. 
Published: May 2017

Abstract
Coupling of diethynyldiphenylsilane (1) with aryl halides under Sonogashira conditions affords the symmetrical diarylacetylenes bis(2-methylpyridin-5-yl)acetylene (2), bis(4-fluorophenyl)acetylene (3) and bis(4-trifluoromethylphenyl)acetylene (4) in 60% to 82% yield. In the case of 2, the by-product bis(2-methylpyridin-5-yl)butadiyne (2a) was isolated in 12% yield. The occurring desilylation reaction was investigated by treating bis(phenylethynyl)diphenylsilane (5) under the same conditions. The formation of 1-fluoro-4-(phenylethynyl)benzene (6), 1-trifluoromethyl-4-(phenylethynyl)benzene (7) and (tetrafluoropyridin- 4-yl)ethynylbenzene (8) in 70 to 84% yield and the cleavage of hexaphenylcyclotrisiloxane were observed in all cases.
Bi- and tridentate silicon-based acceptor molecules
Authors: Horstmann Jan , Lamm Jan-Hendrik , Strothmann Till , Neumann Beate , Stammler Hans-Georg , Mitzel Norbert W. 
Published: May 2017

Abstract
Triethynylphenylsilane (1), trivinylphenylsilane (2), diethynyldiphenylsilane (3) and diphenyldivinylsilane (4) were reacted with chlorodimethylsilane yielding the corresponding hydrosilylation products. To increase their Lewis acidity, the Si–Cl functions were directly transferred into Si–C6F5 units by salt elimination reactions leading to the (semi-) flexible molecules 5–8 bearing two or three Lewis-acidic sidearms. With the aim of providing host-guest complexes, the air-stable and readily soluble compounds 5–8 were converted with N- and O-Lewis bases of different size and geometry. In all cases, NMR spectroscopic investigations reveal no formation of Lewis acid-base complexes. X-ray diffraction experiments of host compounds 5–7 show intermolecular aryl…perfluoroaryl interactions of dispersion nature in the solid state. By hydrosilylation of 1 with trichlorosilane the more Lewis-acidic all-trans-tris[(trichlorosilyl)vinyl]phenylsilane (9) was obtained. Its Lewis acidity was further increased by fluorination to yield all-trans-tris[(trifluorosilyl)vinyl]phenylsilane (10); the conversion with nitrogen containing Lewis bases ends up in the formation of insoluble precipitates.
Thyrotoxicosis leading to adrenal crises reveals primary bilateral adrenal lymphoma
Authors: Roque Catarina , Fonseca Ricardo , Bello Carlos Tavares , Vasconcelos Carlos , Galzerano António , Ramos Sância 
Published: May 2017

Summary
Primary adrenal lymphoma is a rare malignancy. It frequently presents bilaterally and with symptoms of adrenal insufficiency. Amiodarone may induce secondary organ dysfunction, and thyrotoxicosis develops in 15% of cases. The symptomatology of both conditions is nonspecific, especially in the elderly, and a high suspicion index is necessary for appropriate diagnosis. A 78-year-old female presented to the emergency department with confusion, nausea and vomiting. She had recently been to the emergency department with urinary tract infection, vomiting and acute hypochloremic hyponatremia. Upon re-evaluation, the leukocyturia persisted and because of TSH 0.01 µU/mL and free-T4 68 (10–18) pmol/L, she was admitted to the Endocrinology ward. Further evaluation supported amiodarone-induced thyroiditis type 2. Sepsis ensued, in the setting of nosocomial pneumonia. Hemodynamic instability, hyponatremia, hypoglycemia and vomiting raised the suspicion of adrenocortical insufficiency. Fluid resuscitation and hydrocortisone led to clinical improvement, and adrenal insufficiency was admitted. The thoracoabdominal tomography suggested an endobronchic primary lesion with hepatic and adrenal secondary deposits (6.6 and 7 cm), but this was confirmed neither on pleural effusion nor on bronchofibroscopic fluid analyses. The adrenals were not accessible for biopsy. Despite high-dose hydrocortisone maintenance, the patient died before definite diagnosis. The autopsy confirmed primary non-Hodgkin lymphoma.

Learning points:

Primary adrenal lymphoma is a rare cause of adrenal insufficiency, but progression can be fast and fatal.

Hyperpigmentation is frequently absent.

The presenting symptoms are nonspecific and might mimic infection. Disproportion of the general state with signs of specific organ symptomatology is a diagnostic clue.

Infection may precipitate adrenal crisis and worsen thyroid function with further adrenal insufficiency exacerbation.

In the context of thyrotoxicosis, there may be little clinical response to a therapeutic trial with standard dose glucocorticoids.

High-dose glucocorticoid substitution may be required to achieve clinical stability in thyrotoxic patients.
Old Polish Discourse on the Sacred and the Profane in the Moral-religious Guide-book, Titled “Tobias the Pious and Diligent Host” (1647)
Authors: Krzysztofik Małgorzata 
Published: May 2017

The article is devoted to the interpretation of the discourse on the sacred and the profane in anonymous moral-religious guidebook titled Tobiasz pobożny i gospodarz dozorny (Tobias the Pious and Diligent Host), published in Krakow in 1647. The author analyses everyday human life and its basic aspects, continually confronting them with the Bible.
This gives an excellent example of intermingling of two spheres of existence in everyday life, in Old Polish literature, i.e. the sacred and the profane. For this reason, the following research objectives are set out: to select those aspects of reality that, in the mentality of the author, belong to the realm of the sacred, and those that are specific to the area of the profane. The phenomenon of persuasive sacralisation of everyday life, the essence of which is to impart sacred aspects to non-sacred phenomena of existence are described, and the methods of entering into the relationship with the sacred, presented in the text are discussed. The author believes that the persuasion presented in Tobias the Pious, established in religious-ontological discourse, is intended for sacralisation of the profane sphere.
Letters of Maria Kuncewiczowa to Her Late Husband
Authors: Wzorek Anna 
Published: May 2017

The article discusses the last book of Maria Kuncewiczowa – a set of twenty-three letters (provided with a postscript) addressed to her deceased husband. The uniqueness of this correspondence, presented in literary form, lies in the fact that the recipient is dead, treated by the sender as someone constantly present in the real world and still associated with the temporality. Listy do Jerzego (Letters to Jerzy) are – as Tadeusz Swat, one of the reviewers say – “an attempt at denial of death, to save Jerzy by love, memory, and literature.”The analysis of the work highlights the occurring axiological categories. It has been demonstrated that Letters to Jerzy is a book about eternal love reaching beyond the grave (in this respect, in stark contrast with Tristan 1946), felt with dignity of old age, and finally transcending into faith. Letters to Jerzy is also an attempt to reduce the suffering of the writer over the loss of her beloved husband. To some extent, therefore, they correspond to her earlier work Cudzoziemka (Foreigner) in which Kuncewiczowa liberates from the negative emotions associated with the death of her mother.

Technology in the Montessori Classroom: Teachers’ Beliefs and Technology Use
Authors: Jones Sara Jolly 
Published: May 2017

As technology becomes ubiquitous in society, there is increasing momentum to incorporate it into education. Montessori education is not immune to this push for technology integration. This qualitative study investigates four Upper Elementary Montessori teachers’ attitudes toward technology and technology integration in a public school setting. Interviews and observations were used to understand the teachers’ thoughts and actions regarding technology in the classroom. Both the school context and teacher background played important roles in teachers’ beliefs and actions. Teachers in this study expressed positive views of technology in general, exhibiting high technology efficacy and valuing the development of technology skills in their students. However, all four teachers struggled to include instructional technology in ways that are consistent with a Montessori paradigm. Although individual student use of adaptive tutoring software was the most common use of technology, the teachers varied greatly in both the amount of student time spent on computers and the roles that technology played in their classrooms.
Images of Revolution: An American Photographer in Petrograd, 1917
Authors: Mould David H. 
Published: May 2017

Photographer Donald Thompson arrived in Petrograd on the eve of the February Revolution in 1917. Over the next six months, he photographed demonstrations and street-fighting, was caught in crossfire, arrested, and thrown in jail. He traveled to Moscow and the front lines, and photographed Tsar Nicolas II, political and military leaders, and prominent foreign visitors. He witnessed the power struggle between the Provisional Government and the Petrograd Soviet, and the breakdown of discipline in the army. Donald Thompson in Russia, a compilation of letters to his wife with photos, published in 1918, outlines his conspiracy thesis that “German intrigue, working among the unthinking masses, has brought Russia to her present woeful condition.”
