“El poder está en el mar”. La expedición de los hermanos Nodal (1618-1619)
Authors: Rodríguez Couto David
Published: December 2018

La expedición de los hermanos Nodal al estrecho de Magallanes y Tierra de Fuego (1618-1619) se llevó a cabo en vísperas de la finalización de la Tregua de los Doce Años (1609-1621), entre la República de Holanda y la Monarquía Hispánica para verificar el nuevo paso interoceánico descubierto por la expedición holandesa comandada por Jacob Le Maire y Willem Schouten en 1616. Este artículo pretende realizar un nuevo análisis de esta expedición escasamente tratada por la historiografía para aproximarnos al significado que tuvo en el contexto político de aquel tiempo que gira en torno a una idea: el dominio de los mares. Esta idea se manifestó durante el reinado de Felipe III tanto en el plano material como en el plano ideológico y tuvo sus influjos en la organización de esta expedición marítima. Los logros náuticos y cartográficos de la misma demuestran la capacidad material y el potencial humano de la Monarquía Hispánica a inicios del siglo XVII. Su éxito también se debió a una cooperación ibérica, posible en aquel tiempo en el que las coronas de España y Portugal estaban unidas en un mismo destino.

XVIII; as políticas referentes à promoção da cultura e, finalmente, analisamos um estudo de caso: a precoce introdução da cultura num couto senhorial e a sua propagação na região de Coimbra, desde os espaços litorâneos até às regiões montanhosas do interior.
El proceso de difusión de la patata en Cataluña. Una revisión de las tesis elitistas o institucionalistas
Authors: Congost Rosa
Published: December 2018

En Cataluña, como en muchas regiones europeas, se halla muy arraigada la idea de que un producto alimentario nuevo, para tener éxito y universalizarse, requiere de la intervención de una institución o de una élite que lo propague entre el conjunto de la población dedicada a la agricultura. A pesar de las escasas noticias empíricas disponibles, la historiografía catalana ha aplicado esta tesis a la difusión de la patata a fines del siglo XVIII y principios del XIX. Sin embargo, la relectura de los testimonios escritos por algunos viajeros y pensadores ilustrados de fines del siglo XVIII y, en especial, los realizados por el médico Juan Francisco Bahí entre 1815 y 1821, que habían servido de base a esta tesis, y el carácter silencioso del proceso real de difusión del tubérculo, sugieren que, a diferencia de lo que habíamos tendido a pensar, el pequeño campesinado pudo jugar un papel más activo y decisivo en ese proceso de difusión.
Comercio y comerciantes de productos coloniales en Galicia durante el monopolio con América, 1765-1778
Authors: Dubert Isidro
Published: December 2018

En este trabajo atendemos a las transformaciones que experimentó la tradicional estructura comercial que existía en el noroeste de Galicia a consecuencia de los efectos generados, entre otros factores, por la habilitación del puerto de A Coruña para comerciar con América. Dichas transformaciones son abordadas durante la fase del monopolio (1765-1778), gracias a informaciones relativas a la entrada y descarga de coloniales en los muelles de la ciudad de los barcos correo. Asistimos así a la constitución de un mercado de géneros ultramarinos basado en la importación, en torno al cual nace y se desarrolla el embrión de una élite comercial, mayoritariamente foránea, en cuyo seno destacan en sobremanera no más de una docena de personas. En los márgenes de esa elite se situaban muchos pequeños y medianos compradores, entre los que sobresalían los integrantes de las tripulaciones de los citados barcos correo, una parte importante de ellos originarios del Señorío de Vizcaya. Un mercado que, asimismo, nos sitúa en el origen de las transformaciones que conoció alguno de los principales de ramos de la industria gallega de la época, caso, por ejemplo, de la vinculada al trabajo del cuero.
Algunas precisiones en torno al alcance de las consecuencias económicas, sociales y demográficas del cultivo de la patata en la Galicia de finales del Antiguo Régimen
Authors: Sobrado Correa Hortensio
Published: December 2018

Entre los objetivos de este trabajo está hacer algunas precisiones acerca de la periodización de la introducción y progresión del cultivo de la patata en la Galicia de la Edad Moderna, prestando atención a los factores desencadenantes de su expansión, así como al papel jugado en la difusión de la nueva planta por la iniciativa campesina frente al fomento institucional. Igualmente, se pretende precisar el alcance de las consecuencias económicas, sociales y demográficas que desde finales del siglo XVIII y a lo largo de la primera mitad del XIX tuvo la implantación de las patatas en el sistema agrario gallego,  a fin de aquilatar el verdadero protagonismo que dicho tubérculo de origen americano adquirió en  territorio gallego.

Nojus Feigelmanas is a bibliographer and a librarian known for his significant contribution to the history of Lithuanian culture. Consistent and targeted book-related activities pursued by Feigelmanas throughout his life-span have earned him the status of a bookscientist. He was born in Panevėžys on 8 February, 1918. During the period of 1931-1936 he studied in the private Panevėžys Jewish Gymnasium. In 1936-1940 he studied geodesy at Vytautas Magnus University, but failed to complete his studies as he was called up to the army when World War II was launched. In 1959, N. Feigelmanas graduated the Faculty of History and Philology at Vilnius University. In 1950-1990, he worked at the Vilnius University Library: having started career as a bibliographer, he became Head of the Rare Print Department and retained this position for more than three decades. Later in life, in 1990, he moved to Israel and died there on 7 September, 2002, in the city of Ashkelon. The printed catalogues compiled by N. Feigelman are as follows: “The Old Lithuanian Book at Vilnius University” (1959), “The Incunabula of Lithuania” (1975), “The paleotypes of Vilnius University Library” (2003, posthumously, co-authored). He has also published three dozen scientific articles, organized scientific exhibitions, cultural programs on television, etc.

The article aims at disclosing N. Feigelmanas’s path toward book science and his contribution to the development of Lithuanian book science. It also identifies the key factors that have shaped his personality, the choice of the librarian’s profession which ignited his interest in book study, and analyses the directories compiled by N. Feigelmanas and the scientific articles. The conclusion has been drawn that during his long life, from the very young days, when he first read Torah at school, visited book fairs and exhibitions as a gymnasium student, throughout his career at the scientific Vytautas Magnus University Library and small military libraries, to the end of his life, even after he emigrated to Israel – the book remained his lifelong companion.
Lietuvos pirmosios nepriklausomybės laikų knygrišys Zigmas Malašauskas

[full article and abstract in Lithuanian; abstract in English]

Zigmas Malašauskas is a little known interwar period bookbinder who lived and worked in Kaunas in the 1930s. After collecting and evaluating archival sources and publications, his extraordinary ambitions and active public educational activities with the purpose to promote his profession, the need and understanding of artistic bindings, to raise the level of craft and the qualification of his colleagues bookbinders were revealed. His lively articles in the press were dedicated both to the general public (a consumer) and masters of bookbindery. Also, letters to some public authorities and public organizations that deal with various, often naive but reasoned requests or proposals, reveal the real intention to seek the attention, co-operation and support of the state, and to prove the importance of this kind of art.

Although his efforts did not received response and were not acomplished, his articles probably influenced the development of the book lovers community of that time. And most important, since he was the only one that has been writing so much on bookbindery, he left many reliable data (verified by other sources too) for a nowadays researcher about bookbindery and its problems, masters and prices, stastistics and estimations, working methods, learning resources, acquired knowledge, skills and tools.

The research did not lead to identification of any books bound by this bookbinder. Still there are left many unknown biographical facts, therefore it is expected that this article will encourage or facilitate further research of this person’s life and work, to discover and identify his bindings.

Martyno Liudviko Rėzos lietuviška biblija (1816) – evangelikų liuteronų ir Moravijos bažnyčių solidarumo liudijimas
Authors: Strungytė-Liugienė Inga
Published: December 2018

[full article and abstract in Lithuanian; abstract in English]

The copy of Lithuanian Bible printed in Heinrich Degen’s publishing house in Königsberg in 1816 (sign.: BS 17.0/1) has been found in the Unity Archives – Moravian Archives Herrnhut (Herrnhuter Unitätsarchive). This copy was not recorded in the national bibliography of Lithuanian books and did not play a role in the circulation of scholarly knowledge. Christian Friedrich Cunow, the preacher of the Moravian Church and the leader of Brethren Society (Brüdersozietät) of Königsberg, left a donation note in this copy (in the fore title) with the comment that he donates the copy of Lithuanian Bible printed Königsberg to the library of the Unity of the Brethren (Brüder-Unität). This note encouraged [the author of this article] to gather more information about the above person and provided an impetus to find out more about his relationship with the Königsberg Bible Society officially established in 1810. It was found that Cunow was the member of the Society, along with clergymen of traditional Evangelical Lutheran Church – Ludwig Martin Rhesa (1776–1840), Ludwig Ernst Borowski (1740–1831), Samuel Gottlieb Wald (1762–1825) and Carl August Wilhelm Werner (1763–1846). As a member of the Society, he had the following responsibilities: to communicate with the British Bible Society, provide reports to them, take care of support for the publication of Lithuanian Bible and its distribution in Prussian Lithuania. Perhaps the most intriguing fact left unnoticed and not highlighted in the historiography was that not only the members of the traditional Evangelical Lutheran Church, but also the follower of the Moravian Movement contributed to the efforts in publishing and distributing the Lithuanian Bible. Cunow’s involvement in the Königsberg Bible Society is considered as a sign of solidarity between the two denominations in Prussian Lithuania in the first half of the 19th century.
New unique existence criteria for higher-order nonlinear singular fractional differential equations
Authors: Wang Hui , Zhang Lingling , Wang Xiaoqiang
Published: December 2018

In this paper, a nonlinear three-point boundary value problem of higher-order singular fractional differential equations is discussed. By applying the properties of Green function and some fixed point theorems for sum-type operator on cone, some new criteria on the existence and uniqueness of solutions are obtained. Moreover, two iterative sequences are given for uniformly approximating the positive solution, which are important for practical application. At last, we give two examples to illustrate the main results.
On the possibility of remote detection of conductive layers
Authors: Barashkov Aleksandr S.
Published: December 2018

A two-dimensional medium is considered in which the fields are described by the Helmholtz equation. The linearized formulation of the problem of restoring the parameters of the medium (the inverse problem for the Helmholtz equation) is studied. The conditions for the uniqueness of detection of thin conducting layers are established. Examples are given of the multivaluedness of the solution of the inverse problem in information, which was initially thought to be even redundant for an unambiguous solution.
A note about the deterministic property of characteristic functions
Authors: Norvidas Saulius
Published: December 2018

We study an extension property for characteristic functions f : Rn → C of probability measures. More precisely, let f be the characteristic function of a probability density φ on Rn, and let Uσ = {x ∈ Rn: mink|xk| > σ}, σ > 0, be a neighborhood of infinity. We say that f has the σ-deterministic property if for any other characteristic function g such that f = g on Uσ, it follows that f ≡ g. A sufficient condition on f to has the σ-deterministic property is given. We also discuss the question about how precise our sufficient condition is? These results show that the σ-deterministic property of f depends on an arithmetic structure of the support of φ.
Global Health Education for Pediatric Residents: Trends, Training Experiences, and Career Choices
Authors: Pak-Gorstein Suzinne , Frintner Mary Pat , O’Callahan Cliff , Spector Jonathan , St Clair Nicole E. , Howard Cindy , Anspacher Melanie
Published: December 2018

BACKGROUND AND OBJECTIVES:

Knowledge and skills related to global child health are increasingly recognized as important to the practice of pediatrics. However, little is known about the status and trends in global health (GH) education in US pediatric residency programs. Our aim was to measure trends in residents’ exposure to GH training, their GH education assessments, and GH career plans.

METHODS:

We analyzed GH-focused questions from national American Academy of Pediatrics surveys of graduating residents in 2008 and 2016. Logistic regression was used to estimate changes over time by using derived predicted values.

RESULTS:

A total of 1100 graduating pediatric residents participated; response rates were 58.8% for 2008 and 56.0% for 2016. The percentage of residents reporting that their programs offered GH training grew from 59.1% in 2008 to 73.1% in 2016 (P < .001). The majority were somewhat likely, very likely, or definitely planning to work or volunteer in a low- or middle-income country after their residency (predicted value of 70.3% in 2008 and 69.4% in 2016; P = .76). Fourteen percent of respondents reported having completed an international elective in 2016; of those, 36.5% did not receive formal preparation before the experience, and 24.3% did not participate in debriefing sessions on return. Overall, 27.3% of respondents in 2016 reported excellent (8.8%) or very good (18.5%) GH training.

CONCLUSIONS:

Although a substantial percentage of pediatric residents participate in international electives and plan to include GH activities in their careers, gaps remain, including suboptimal preparation and debriefing for GH electives.
Spatial Development of Russia: Regional Disproportions
Authors: Moroshkinа Marina V.
Published: December 2018

Introduction. The topic of interregional differentiation is relevant due to the existing increase in disproportions in the Russian regions, which has an impact on the development of the state economy. The main objective of the study is to assess the level of interregional differentiation.

Materials and Methods. The study used the indicator of “general entropy”, in particular, the Theil index. The research methodology includes economic and mathematical methods of data processing, statistical data analysis packages, etc.

Results. In the course of the work, the research tasks were set and fulfilled: the development of Russian regions in the period of structural transformations was analyzed; indicators making it possible to assess the level of economic development of territories were provided; a coefficient was chosen, based on the calculation of which the level of interregional differentiation was estimated; the level of interregional differentiation was assessed. It has been proved that the periods of economic growth are characterized by faster rates of development of weak regions due to the state support and redistribution of budgetary funds mitigating territ orial differences. During the periods of economic recession, the state support is provided to the regions with competitive advantages, capable of changing the negative dynamics of the country’s economic development in order to accelerate economic growth.

Discussion and Conclusion. The results achieved can be used when designing the program of development of economic entities or drafting strategic documents. Interregional differences and disparities in most territories determine the dynamics of their development and the opportunities for economic growth, on which the economic policy pursued by the regional authorities should be based. In a competitive environment, the identification and further gaining strength from the advantages of the regions make it possible to form the policy of the region’s development which helps to make management decisions.
Agglomeration Processes in the European North of Russia: Experience of the Vologda Region
Authors: Kozhevnikov Sergei A.
Published: December 2018

Introduction. The processes of urbanization are a global trend and lead to the formation and further development of agglomerations as new forms of effective organization of urban and rural areas connected with each other by long-standing links. The specifics of the modern stage are the development of agglomeration processes in the territories the cores of which are large and medium-sized cities. However, the features of the integration processes in such agglomerations have not been studied fully, which makes this study relevant. The purpose of the paper is to analyze the peculiarities of the development of agglomerations in the regions of the European North of Russia, the cores of which are large cities, and to make the case for a range of activities for managing these processes.

Materials and Methods. The object of the research was the emerging monocentric Vologda agglomeration. To study the features, problems and prospects of its formation, an analysis of key trends and patterns of the development of these territories was performed; sociological research was conducted among residents and the heads of municipalities regarding the features, problems and prospects for the formation of integration links.

Results. It has been proved that the Vologda agglomeration belongs to the category of monocentric, least developed and emerging ones, but it meets all the criteria for delimitation of agglomerations. The presence of close industrial, cooperative, cultural, recreational and other links of intra-agglomeration territories was revealed. The hypothesis has been confirmed that the strength of agglomeration processes directly depends on the size of the core; large and medium-sized cities do not have such agglomeration potential as million-plus cities. A range of activities for the management of these agglomeration processes has been substantiated.

Discussion and Conclusion. Although the agglomeration processes in the Vologda Region are objective, the identified links are still developing. Further research may focus on the development of the strategy and program for the development of the Vologda agglomeration.
Exploring relationships between problem gambling, scratch card gambling, and individual differences in thinking style
Authors: Stange Madison , Walker Alexander C. , Koehler Derek J. , Fugelsang Jonathan A. , Dixon Mike J.
Published: December 2018

Background and aims

Scratch cards are a popular form of lottery gambling available in many jurisdictions. However, there is a paucity of research that examines associations between individual differences in thinking style, participation in scratch card gambling, and problem gambling severity.

Methods

In three studies, we sought to examine the relationships among these variables in large, online samples of participants. Participants completed the Cognitive Reflection Test (CRT), the Problem Gambling Severity Index (PGSI), the Actively Open-Minded Thinking Scale, and self-reported their frequency of scratch card gambling.

Results

Throughout all three studies, specific associations were reliably established. Specifically, negative associations were observed between participants’ CRT and PGSI scores, as well as between participants’ CRT scores and scratch card gambling frequency. In addition, we found a positive association between problem gambling severity and scratch card gambling frequency. Finally, problem gambling severity was shown to correlate positively with participants’ willingness to pay for irrelevant information in a scratch card gambling scenario.

Discussion and conclusions

Overall, we observed that problem gambling severity is associated with an individuals’ thinking style and scratch card gambling behavior. This study adds to the existing literature examining problem gambling, and highlights the role of thinking style in understanding gambling behavior and problematic gambling.
Two-dimensional modeling of organic field effect transistors
Authors: Li T. , Ruden P. P. , Campbell I. H. , Smith D. L.
Published: December 2018

We present device simulations for p-channel organic field effect transistors. The current conservation equation and Poisson's equation are solved self-consistently in two dimensions in the drift-diffusion approximation. We focus on modeling transistor structures consisting of a gate electrode, a silicon dioxide gate insulator, and a pentacene or a conjugated polymer layer as the active (channel) material. The source and drain contacts are taken to be deposited directly on the gate insulator (bottom contact structure). We examine the effects associated with differences in charge carrier injection for different source and drain contact materials. It is also shown that, if the organic material immediately adjacent to the contacts has poor conduction properties, ‘parasitic’ source and drain series resistances that depend on the contact/organic injection barrier height as well as the channel material mobility can result.

Published: December 2018

The transport properties of poly(2,5-thienylene vinylene) (PTV) field-effect transistors (FET) have been investigated as a function of temperature under controlled atmosphere. In a disordered semiconductor as PTV the charge carrier mobility, dominated by hopping between localized states, is dependent on the charge carrier density. The transfer characteristics of PTV FET have been modeled considering the distribution of charge carriers and mobility over the accumulation channel. Good agreement with the experimental data is obtained.

Pentacene Thin Film Transistors and Circuits: Influence of Processing and Device Design
Authors: Knipp D. , Street R. A. , Krusor B. , HO J.
Published: December 2018

The influence of different dielectrics on the structural and electronic properties of pentacene films and TFTs is discussed. The pentacene films were thermally evaporated on inorganic dielectrics compatible with flexible substrates. A strong correlation between morphology and structural properties of the pentacene films and the mobility of the TFTs was observed for all the dielectrics studied. In the case of plasma enhanced chemical vapor deposited (PECVD) silicon nitride and silicon oxide dielectrics the growth of pentacene is mainly determined by the roughness of the dielectric. The roughness inhibits the ordering of pentacene molecules on the surface. However, by optimizing the fabrication process of the dielectrics, we have achieved similar pentacene mobilities on PECVD dielectrics and thermal oxide (0.4 cm2/Vs), without employing self-assembled monolayers like octadecyltrichlorosilane (OTS). An OTS treatment of oxide based dielectrics leads to an increase of the mobility by a factor of 2-3 up to >1cm2/Vs for thermal oxide. Pentacene films on inorganic dielectrics exhibit mobilities from of 0.2-1.2 cm2/Vs and high on/off ratios between 107 and 108.

Organic field-effect transistors (OFETs) are “soft material” versions of accumulationmode silicon-based FETs, where a gate field across a dielectric induces a conductive charge channel at the interface of the dielectric with a semiconductor, between source and drain electrodes. Charge carrier mobilities >0.01 and on/off ratios >10,000 are routinely obtained, adequate for a few specialized applications such as electrophoretic pixel switches but well below standards established for silicon microprocessor technology. Still, progress that has been made in solution-phase semiconductor deposition and the printing of contacts and dielectrics stimulates the development of OFET circuits for situations where extreme low cost, large area, and mechanical flexibility are important. Circuits with hundreds of OFETs have been demonstrated and a prototype OFETcontrolled black-on-white “electronic ink” sign has been fabricated.

Published: December 2018

This work describes the properties of an organic-inorganic hybrid gel with an incorporated I-/I3-redox couple that serves as a solid electrolyte for a dye-sensitized TiO2 photoelectrochemical (DSPEC) cell with an efficiency of 4% [1]. The influence of the AcOH on the hydrolysis and condensation reactions of the gels was studied with the help of infrared spectroscopy, while the presence and the formation of the I3 - species were established from the UV-visible spectra of the gels and independently evaluated from the confocal micro-resonance Raman spectra of the electrolyte encapsulated in the DSPEC during open- and short-circuit conditions. Finally, the same gel electrolyte was used for the construction of an electrochromic (EC) window without a counter electrode with intercalation properties (transmission and reflective configuration).
Spin-Dependent Recombination in PPV and Polyfluorene LEDs
Authors: Dhoot Anoop S. , Greenham Neil C.
Published: December 2018

In a polymer light-emitting diode, the fraction of excitons formed as singlets is of crucial importance in determining the quantum efficiency. We have shown that it is possible to measure excited state absorptions due to triplet excitons and polarons in working polymer LEDs, and we are able to quantify the triplet generation rate by measuring the strength of the triplet absorption. Here, we show that by careful study of singlet emission and triplet absorption in an LED based on a poly(p-phenylenevinylene) derivative we can obtain an accurate value of 83±7% for the singlet formation probability, significantly higher than the value of 25% predicted by simple spin statistics. We extend these measurements to devices based on poly(dioctyl-fluorene), where we find similarly high values for the singlet formation probability. In devices using the polyfluorene copolymer F8BT, we find that the triplet absorption is extremely small, consistent with even higher singlet formation probabilities.

Authors: Blom Paul W.M. , Woudenbergh Teunis van , Huiberts Hans
Published: December 2018

The electro-optical characteristics of a polymer light emitting diode (PLED) with a strongly reduced hole injection have been investigated. The device consists of a poly-p-phenylene vinylene semiconductor with a Ag hole injecting contact, which has an injection barrier of about 1 eV. It is observed that the light and current density of such an injection-limited PLED strongly exceed the expected device characteristics. Numerical calculations of the injection-limited PLED show that the enhanced performance can be explained by a very high electric field at the hole injecting contact, due to trapped electrons.

The X-ray structural analysis of di-L-valine selenate monohydrate has been carried out (P21, a=6.181(2), b=18.675(3), c=15.342(4)Å β=90.14(2)°, V=1770.8(7) Å3, Z=4, R=0.0532 for 3057 observed reflections). The crystal structure is formed by selenate anions, L-valinium cations and water molecules (in the ratio of 1:2:1) interconnected by a system of hydrogen bonds. The FTIR (298-90 K temperature range) and FT Raman spectra were recorded and interpreted. DSC measurements were carried out in the temperature range 95-363 K. Quantitative SHG measurements of di-L-valine selenate monohydrate and tri-L-valine selenate were carried out on powdered samples.
Triplet-Triplet Energy Transfer in Photocrosslinkable Dendrimers
Authors: Furumi Seiichi , Otomo Akira , Yokoyama Shiyoshi , Mashiko Shinro
Published: December 2018

This report describes the synthesis of photocrosslinkable dendrimers with peripheral cinnamamide residues, which exhibit both photoisomerization and photodimerization, and their photochemical and photophysical properties in dilute solutions and polymer matrices. Photoirradiation with 313 nm gave rise to monotonous decrease in the absorbance of trans-cinnamamide at 270 nm as a result of the photochemical reactions of the cinnamamide residues. Spectral analysis revealed the changes in the photoproduct distribution of trans- and cis-photoisomerized and photodimerized cinnamamide groups to be a function of the exposure energy. In dilute solutions, the first-generation dendrimer displayed preferential formation of cis-isomer of the cinnamamide, whereas the photodimerization took place more favorably for the third- and fifth-generation dendrimers. The photochemical behavior was strongly dependent on the dendrimer generation rather than the concentration, probably due to the extent of steric crowding among the cinnamamide residues at terminal positions. Furthermore, the third- and fifth-generation dendrimers showed capturability of a benzophenone derivative into the macromolecules and triplet-triplet energy transfer in the photocrosslinkable dendrimers. This novel phenomenon of the triplet-triplet energy transfer in the dendritic cavities suggests potential applicability to design and fabricate novel optical and electrical molecular devices.

Quando compara-se peças publicitárias dos anos 1960 às mensagens comerciais contemporâneas, é possível observar a ascensão de valores ligados ao individualismo expressivista descrito por Taylor (1991, 2005, 2007) e Bellah (1996). A arte não mais serve apenas como distintivo de nobreza cultural, como ocorria nos anos 1960, mas como uma forma de expressão a singularidade pessoal. A ênfase nos modos de expressão pessoal dada pela publicidade atual permite expandir algumas considerações de Boltanski e Chiapello (2009) acerca do novo espírito do capitalismo e refletir sobre a figura do artista na contemporaneidade.

Synthesis of core–shell soap-free emulsion and evaluation of its performance in oil-well cement
Authors: Peng Zhi-gang , Wu Jia-rong , Feng Qian , Zhang Jian , Zhang Bo-jian
Published: December 2018

A soap-free latex (XY-5) was prepared by means of a soap-free emulsion free-radical polymerisation method, using the synthetic polymer P (BA/AANa) as an emulsifier and butyl acrylate (BA), styrene and methyl methacrylate as monomers. The stability, thermal stability and microstructure of the XY-5 emulsion were studied using various methods, including viscosity analysis, zeta potential measurement, thermogravimetric analysis and transmission electron microscopy. The emulsion was found to have high stability and good heat resistance, with the latex particles exhibiting a typical core–shell structure. Its performance as an oil-well cement was also evaluated. The results showed that the XY-5–cement slurry has good temperature resistance, salt resistance, low water loss and low permeability. Furthermore, the use of XY-5 effectively improved the cementation strength. Scanning electron microscopy showed that the XY-5 latex forms a three-dimensional network structure inside the cement, with cement particles linked together by latex particles. The comprehensive performance of XY-5 latex was found to be much better than the THD-815 latex on the market.
Risk Game: Capturing impact of information quality on human belief assessment and decision making
Authors: Jousselme Anne-Laure , Pallotta Giuliana , Locke John
Published: December 2018

This paper presents the Risk Game, a general methodology to elicit experts’ knowledge and know-how, in their ability to deal with information provided by different types of sources (sensors or humans) of variable quality, to take into account the information quality and to reason about concurrent events. It is a contrived technique capturing data expressing human reasoning features during a specific task of situation assessment. The information is abstracted by cards and its quality, which varies along the three dimensions of uncertainty, imprecision and falseness, is randomly selected by dice roll. The game has been played by experts of maritime surveillance, mostly marine officers from several nations. The Risk Game is domain-independent and can be designed for any specific application involving reasoning with multi-sources. The preliminary results obtained are promising and allow validating the efficiency of the elicitation method in capturing the link between information quality and human belief assessment. Besides the positive feedback collected from the players and their perceived effectiveness of the method, the data effectively capture the impact some specific information quality dimensions on belief assessment. We highlight, for instance, that the relevance of information perceived by the players may differ from the effective information relevance, that a high ratio of false information increases the uncertainty of the player before decision and may lead to wrong decisions, or that the context has a high impact on the decision made. Future extensions of the Risk Game are finally sketched.
Games for Cross-Cultural Training
Authors: Nyman Gomez Christian , Berg Marklund Björn
Published: December 2018

This paper studies whether a board game can effectively raise awareness of cultural differences and their impacts on everyday life. Furthermore, the paper compares whether a board game might achieve this goal more efficiently, or differently, than more traditional ‘open discussion’ exercises. To conduct this study, a board game that present players with cultural dilemmas was designed and developed based on a comparative model of individualistic and collectivistic cultures. The game’s ability to generate discussion and engagement with cross-cultural topics was evaluated and compared with traditional discussion exercises in a series of experimental studies conducted in SFI (Swedish For Immigrants) classrooms. A follow-up survey was also conducted to compare long-term effects between the board game and the traditional discussion exercise. Results indicate that the game benefited participants’ discussions and reflections regarding cultural awareness directly after the game session, and that they retained their attitudes and perceptions of cultural awareness better than participants of the non-game exercise.

Las redes de salud en el Territorio del Gran Buenos Aires: el desafío de la coordinación de servicios de salud
Authors: Crojethovic Maria , Ariovich Ana
Published: December 2018

A partir de un desarrollo teórico instrumental, se analizan la estructura, la amplitud y la organización de las redes de servicios de salud en el conurbano bonaerense, recuperando aportes de la teoría de las organizaciones y de la literatura sobre redes. Se seleccionaron 17 redes para un estudio más exhaustivo. Las redes abordadas tienen distintos alcances territoriales y se apoyan en programas de salud nacional y/o provinciales preexistentes. Están presentes en establecimientos de alta complejidad y en el primer nivel de atención, pero operan desde una lógica hospitalocéntrica.
Gender, Class and Bureaucratic Power: The Production of Inequalities in the French Civil Service
Authors: Revillard Anne , Jacquemart Alban , Bereni Laure , Pochic Sophie , Marry Catherine
Published: December 2018

Este artículo examina las lógicas detrás de la tenaz persistencia de las desigualdades de género en las carreras del servicio público en Francia, basado en 95 entrevistas biográficas realizadas con funcionarios en puestos de alta dirección y ejecutivos entre 2011 y 2013. El estudio combina la atención a las consecuencias del contexto organizacional con análisis de la interacción entre género y clase, centrándose especialmente en la forma en que los gerentes y los ejecutivos se apropian de las políticas de igualdad. Si bien los antecedentes familiares tienen impactos diferenciales en las trayectorias y orientaciones educativas de mujeres y hombres, encontramos que las burocracias administrativas gubernamentales también contribuyen fuertemente a la producción de tales diferencias a través de las reglas y normas que las políticas de igualdad luchan por cambiar, especialmente en tiempos de austeridad e intensificación de las reformas de la “nueva gestión pública”. Si bien la mayoría de los gerentes y ejecutivos de ambos sexos tienden a negar las causas organizativas y sociales de la desigualdad, la difusión de normas igualitarias fomenta la expresión de la conciencia de género por una minoría de mujeres y reestructura las masculinidades y eminidades gerenciales.
Las ocupaciones en los servicios de limpieza y de estética: algunas pistas para reflexionar en torno de la movilidad laboral de las mujeres de sectores populares en Argentina
Authors: Gorban Débora , Tizziani Ania
Published: December 2018

Este artículo se propone indagar en torno de los patrones de segregación multidimensionales de género y sector socioeconómico en el mundo del trabajo para el caso de la ciudad y área metropolitana de Buenos Aires. Para ello analizaremos las experiencias de trabajo de las mujeres de sectores populares centrándonos en los servicios de limpieza y en las ocupaciones de estética. Se trata de las ocupaciones más representativas y también unas de las más desfavorable del mercado de trabajo (en términos de niveles de salario y condiciones de trabajo). En base a una investigación que venimos desarrollando desde el 2009 buscamos no solo caracterizar estas ocupaciones sino la manera en que las trabajadoras se desplazan entre ellas y los significados que le atribuyen a esta movilidad.

Published: December 2018

A nivel internacional hay diferentes experiencias de cooperativas de vi- vienda. Mientras que en España es una iniciativa reciente. Ante esta realidad, la investigación se centra en el rol del liderazgo en las cooperativas de vivienda en Ca- taluña, así como en la capacidad democrática e innovadora dentro de las mismas. Concretamente, el estudio se centra en dos estudios de caso de cooperativas: Lacol y La Borda. Lacol es la cooperativa de arquitectura que está realizando el diseño arqui- tectónico de La Borda (cooperativa de viviendas en cesión de uso). En el análisis, se incorporan las voces de los miembros de ambas cooperativas a través de entrevistas en profundidad. En los resultados, se señala el impacto del liderazgo en las cooperativas en relación con los procesos de innovación y creación social. En conclusión, el estudio presenta una forma de organización cooperativa que se adapta a los desafíos de la vivienda y los supera dando una respuesta innovadora que fomenta la gestión comu- nitaria y el acceso a la vivienda.

Sensitive periods and developmental pathology of psychological functions among children with paroxysms
Authors: Turovskaya N.G.
Published: December 2018

The paper describes the results of a psychological research of specificities of psychological functions development among children with paroxysms depending on their age and the duration of a disease. Fifty-four children aged 6—8 years old and their parents participated in the study. Clinical biography and experimental-psychological methods were used in the study (methods of neuropsychological research of higher psychic functions among children, Tsvetkova, 2002)), a diagnostic complex (“Prognostic and prevention of learning difficulties in school; Yasukova, 2002). The results showed that an early development of paroxysms is coupled with difficulties in auditory perception, short term memory, visual linear thinking and motor functions difficulties. The prolongation of paroxysms in preschool year-old children is coupled with a developmental pathology of kinesthetic praxis, as well as language and thinking, linked to language. It is hypothesized that developmental difficulties in children with paroxysms are related to the specificities of their impairments, as well as the sensitive periods of psychological functions.
