Small Intestinal Bacterial Overgrowth Is Common in Chronic Pancreatitis and Associates With Diabetes, Chronic Pancreatitis Severity, Low Zinc Levels, and Opiate Use
Authors: Lee Allen A. , Baker Jason R. , Wamsteker Erik J. , Saad Richard , DiMagno Matthew J.
Published: April 2019

OBJECTIVES:

Small intestinal bacterial overgrowth (SIBO) is often present in patients with chronic pancreatitis (CP) with persistent steatorrhea, despite pancreatic enzyme replacement therapy. Overall prevalence of SIBO, diagnosed by glucose breath test (GBT), varies between 0% and 40% but 0%–21% in those without upper gastrointestinal (GI) surgery. We investigated the prevalence and nonsurgical independent predictors of SIBO in CP without upper GI surgery.

METHODS:

Two hundred seventy-three patients ≥18 years old had a presumptive diagnosis of CP and a GBT between 1989 and 2017. We defined CP by Mayo score (0–16) ≥4 and a positive GBT for SIBO by Rome consensus criteria and retrospectively collected data for 5a priorivariables (age, opiates, alcohol use, diabetes mellitus (DM), gastroparesis) and 41 investigational variables (demographics, GI symptoms, comorbidities, CP etiologies and cofactors, CP symptom duration, Mayo score and nondiabetes components, and biochemical variables).

RESULTS:

Ninety-eight of 273 patients had definite CP and 40.8% had SIBO. Five of 46 variables predicted SIBO: opiates,P= 0.005; DM,P= 0.04; total Mayo score,P< 0.05; zinc,P= 0.005; and albumin,P< 0.05). Multivariable analysis of 3 noncorrelated variables identified zinc level (odds ratio = 0.0001;P= 0.03) as the sole independent predictor of SIBO (model C-statistic = 0.89;P< 0.001).

DISCUSSION:

SIBO, diagnosed by GBT, occurs in 40.8% of patients with CP without upper GI surgery. In patients with CP, markers of more severe CP (low zinc level, DM and increased Mayo score) and opiate use should raise clinical suspicion for SIBO, particularly in patients with persistent steatorrhea or weight loss despite pancreatic enzyme replacement therapy.
Harnack inequalities for curvature flows in Riemannian and Lorentzian manifolds
Authors: Bryan Paul , Ivaki Mohammad N. , Scheuer Julian
Published: April 2019

We obtain Harnack estimates for a class of curvature flows in Riemannian manifolds of constant nonnegative sectional curvature as well as in the Lorentzian Minkowski and de Sitter spaces. Furthermore, we prove a Harnack estimate with a bonus term for mean curvature flow in locally symmetric Riemannian Einstein manifolds of nonnegative sectional curvature. Using a concept of “duality” for strictly convex hypersurfaces, we
also obtain a new type of inequality, so-called “pseudo”-Harnack inequality, for expanding flows in the sphere and in the hyperbolic space.
Artinian bimodule with quasi-Frobenius bimodule of translations
Authors: Nechaev Aleksandr A. , Tsypyschev Vadim N.
Published: April 2019

The possibility to generalize the notion of a linear recurrent sequence (LRS) over a commutative ring to the case of a LRS over a non-commutative ring is discussed. In this context, an arbitrary bimodule AMB over left- and right-Artinian rings A and B, respectively, is associated with the equivalent bimodule of translations CMZ, where C is the multiplicative ring of the bimodule AMB and Z is its center, and the relation between the quasi-Frobenius conditions for the bimodules AMB and CMZ is studied. It is demonstrated that, in the general case, the fact that AMB is a quasi-Frobenius bimodule does not imply the validity of the quasi-Frobenius condition for the bimodule CMZ. However, under some additional assumptions it can be shown that if CMZ is a quasi-Frobenius bimodule, then the bimodule AMB is quasi-Frobenius as well.
A Wideband Polarization Reconfigurable Antenna Array Based on Mode Combination Method
Authors: Mu Zhuo , Wang Shen-Yun , Meng Wen-Ying
Published: April 2019

This paper reports a novel polarization-reconfigurable antenna array based on the theory of mode combination (MC), which can electronically alter its polarization states between left-hand circular polarization (LCP) mode, right-hand circular polarization (RCP) mode, and two combined linear polarization (LP) modes. The array element is adopted as the L-probes fed circularly-polarized antenna reported by Luk et al. [1]. To verify the concept, a prototype of 2×2 antenna array is manufactured and tested. By properly exciting the feeding probes, four polarization modes can be switchable. Measurement results show that the proposed antenna has an overlapped −10 dB impedance bandwidth around 34 % for both CP modes and LP(2) mode, and an overlapped 3 dB axial-ratio bandwidth around 22.0 % of the CP modes. The average realized gains are around 12.4 dB for CP modes and LP(1) mode, which remain stable in the axial-ratio bandwidth.
A Highly Accurate Collocation Method for Linear and Nonlinear Vibration Problems of Multi-Degree-Of-Freedom Systems Based on Barycentric Interpolation
Authors: Zhuang Meiling , Miao Changqing , Wan Caihong
Published: April 2019

A highly accurate collocation method based on barycentric interpolation (BICM) is proposed for solving linear and nonlinear vibration problems for multi-degree-of-freedom systems in this article. The mathematical model of the linear and nonlinear vibrations of multi-degree-of freedom systems is the initial value problem of the linear and nonlinear differential equations. The numerical solution of the linear differential equations can be directly solved by BICM. The numerical solution of nonlinear differential equations can be solved as following: Firstly, the nonlinear governing equation is converted to linear differential equation by assuming the initial function. Secondly, the linear differential equations are discretized into algebraic equations by using barycentric interpolation differential matrices. Thirdly, the numerical solution can be calculated by iteration method under given control precision. Finally, the numerical solution of calculation examples by using barycentric Lagrange interpolation iteration collocation method (BLIICM) and barycentric rational interpolation iteration collocation method (BRIICM) are compared with the analytical solution. Numerical results illustrate the advantages of proposed methodology are efficient, fast, simple formulations, and high precision. Comparing with BLIICM, BRIICM can still maintain its computational stability when dealing with a large number of nodes, especially the equidistant nodes.
Implicitness and experimental methods in language variation research
Authors: Rosseel Laura , Grondelaers Stefan
Published: April 2019

This special issue brings together research that reflects on the status and role of different types of language attitudes, and the methods required to study them. Many linguists distinguish between explicit and implicit attitudes towards language, but more often than not it remains unclear how these constructs are defined, and what their potential significance is for the study of language variation and change. The contributions to this issue address this question by critically reflecting on theory and methodology, by highlighting (and clarifying) the terminological confusion, and by showcasing new methods and tools. It is hoped that this special issue can inspire theoretical and methodological convergence in a notoriously fragmented field, so that attitude researchers can identify the underlying structure of language attitudes, and the theoretical significance of language evaluation to processes of language variation and change.
The relationship between implicit and explicit attitudes to British accents in enhancing the persuasiveness of children’s oral health campaigns
Authors: Adams Zoe
Published: April 2019

This paper seeks to improve the persuasiveness of oral health campaigns by investigating the relationship between implicit and explicit attitudes to British accents. Forty-seven participants from Tayside, East Scotland, first completed an implicit task which asked participants to judge the truth value of 120 trivia statements, divided into six different accents, as quickly as possible. This was complimented by an identical written task at the end of the experiment in less pressurised conditions. Both audio and written responses to the statements were analysed using signal detection theory, which revealed that Estuary English was more persuasive than the local accent, Dundee English (p = 0.039), and the stigmatised multi-ethnolect, Multicultural London English (p = 0.002). Participants also completed an explicit task involving two matched-guise tests with the same six accents in a neutral and dental context. Results update our knowledge of explicit attitudes to British accents in a modern linguistic landscape, and shed light on correlations between implicit and explicit attitudes. Using Bassili and Brown’s (2005) Potentiated Recruitment Framework, it is argued that the relationship is mediated by participants’ self-presentation concerns and the perceived social penalties of expressing bias. Sociolinguistic implications of implicit measurement procedures are discussed regarding the development of oral health campaigns.
The relational responding task (RRT): a novel approach to measuring social meaning of language variation
Authors: Rosseel Laura , Speelman Dirk , Geeraerts Dirk
Published: April 2019

Recently, sociolinguistic attitude research has adopted a number of new implicit attitude measures developed in social psychology. Especially the Implicit Association Test (IAT) has proven a successful new addition to the sociolinguist’s toolbox. Despite its relative success, the IAT has a number of limitations, such as the fact that it measures the association between two concepts (e.g. ‘I’ and ‘skinny’) without controlling for the relationship between those two concepts (e.g. ‘I am skinny’ vs. ‘I want to be skinny’). The Relational Responding Task (RRT), a novel implicit attitude measure recently developed by social psychologists, makes up for exactly that limitation by presenting participants with full propositions expressing beliefs rather than loose concepts. In this paper, we present a study that explores the RRT as a novel implicit measure of language attitudes. We employ the method to investigate the social meaning of two varieties of Dutch: Standard Belgian Dutch and colloquial Belgian Dutch. In total 391 native speakers of Belgian Dutch took part in the study. A training effect in the data aside, our results show that the latter variety is associated with dynamism, while the former is perceived as prestigious.
An initial record of a long-distance dispersal route of a male sika deer in central Japan
Authors: Takii Akiko , Izumiyama Shigeyuki , Mochizuki Takashi
Published: April 2019

We conducted a global positioning system (GPS) tracking of a male sika deer (Cervus nippon) and his mother in the eastern foothills of the northern Japanese Alps, central Japan. Sika deer exhibited similar seasonal movement patterns; however, the male deer left his natal group at 11 months of age. At 15 months of age, the male deer settled in the neighboring mountain, which was 74 km away from his natal range. This is the first record of long-distance (>50 km) natal dispersal of the sika deer. Our findings might help to explain the expanding distribution of the sika deer.

Published: April 2019

Almond husk liquefaction can be envisaged as an alternative to fossil sources which are becoming exhausted. Lately, the polyols obtain from the lignocellulosic biomass have been under investigation for the production of sustainable chemicals, fuel, materials or other commodities. Within this context, acid-catalyzed liquefaction of such lignocellulosic biomass has been successfully used to access highly functionalized compounds that can be used to replace those produced from petroleum. Almond shells waste can be considered to be part of the lignocellulosic biomass. Its main constituents of are cellulose, hemicellulose, and lignin. In this assay, the biochemical composition of almond husk was estimated based on atomic mass balances, and at the same time, the pyrolysis outcome was also estimated using a kinetic model using some reference compounds. In order to evaluate the use of almond waste as a substrate for acid-catalyzed liquefaction, the most favorable conditions of the liquefaction process were investigated. To better understand the liquefaction process, response surface methodology, in particular, central composite face-centered factorial design was used to set an array of 17 experiments including three replications at the center point leading to the development of a reaction model for further prediction and optimization of the liquefaction outcome. The effect of temperature (120–150 °C), time (20–200 min) and catalyst amount (0.5–5 wt. %) was investigated and a predictive model established.
The Posthumanist Technological Sublime as Cultural Technique: Poe’s “The Man That Was Used Up”
Authors: Sommerfeld Stephanie
Published: April 2019

This essay argues for exploring sublimity as a cultural technique which is central to processing modern practices of purification and hybridization alike, and which also self-reflexively illuminates the operations and actors of its surrounding human-nonhuman network. The dissection and literal assemblage of a romantic cyborg in “The Man That Was Used Up” serves as an example of how Poe’s self-referential employment of a posthumanist technological sublime counteracts anthropocentric notions of Romantic sublimity which reduce Nature to a means of human arousal and self-elevation.

Undrained Interface Shear Strength of Fine-Grained Soils for Near-Shore Marine Pipelines
Authors: Eid Hisham T.
Published: April 2019

The peak and residual interface shear strengths for a variety of normally consolidated soils were measured using a torsional ring shear apparatus modified to suit soil and interface testing under the undrained condition, which is usually prevalent at soil–marine pipeline interfaces. Five solid surfaces with different roughnesses were utilized in this single-stage shear testing program. Tests were conducted at normal stresses in the intermediate range that are mobilized on soil–pipeline interfaces under near-shore conditions. For comparison, drained peak and residual shear strengths of a representative interface were also measured using a different version of the torsional ring shear apparatus. Based on the analyses and interpretations of the test results, a simple equation is introduced to estimate the undrained peak and residual interface efficiencies as a function of the solid surface roughness. The analyses also revealed that the normalized undrained peak and residual shear strengths of the soils and interfaces are insensitive to the change in soil plasticity. The ratios between these undrained strengths and the corresponding drained strengths decrease with decreasing soil plasticity and increasing interface roughness. Recommendations for the initial assessment of the pipe-soil shearing resistance and the preliminary stability analyses of near-shore marine pipelines are suggested based on the findings of this study.
Metallographic Preparation and Characterization of Thermal Barrier Coatings
Authors: Cemprola Michael , VanBezooijen Andrew , O’Leary Leonard
Published: April 2019

Characterization of thermal sprayed thermal barrier coatings (TBCs) continues to challenge metallographers due to the lack of standardized preparation and analysis methods. Despite the past literature on this topic, ASTM E04 has yet to include a preparation method specific for TBCs. The present study aims to bring this topic to the forefront and reinvigorate the standardization in this area of metallography. Each step of metallographic preparation will be discussed to highlight its importance in revealing the true microstructure of a TBC. Modern metallographic characterization techniques will be utilized to identify a preferred preparation method for adoption as standard practice.
Avoid Microindentation Hardness Testing at Low Loads!
Authors: Vander Voort George F.
Published: April 2019

For many years, ASTM E384, Standard Test Method for Microindentation Hardness of Materials, has stated that the load range for microindentation hardness testing with both Knoop and Vickers indenters is 1 gf to 1,000 gf. But, is it realistic to consider using very low-test forces when the indents are measured with a light optical microscope? ASTM E384 also states that tests that produce a Knoop long diagonal or a Vickers mean diagonal of less than 20 μm should be avoided as the precision in measuring such small indents is poor. The standard recommends using loads no lower than 25 gf. This article shows that the Knoop test exhibits better measurement precision at loads of 200 gf and below because the long diagonal is 2.7 times greater in length than the Vickers mean diagonal length for the same specimen tested at identical loads. Knoop, however, does not produce constant hardness values as the load changes. Most microindentation hardness testers provide the user with a 10× objective used to find the area of interest for testing and one measurement objective, with 40× magnification being the most common. A few testers have offered 50× or 60× objectives to measure the indents. It is rare to find a tester with a multiple objective turret. If one can use a 100× objective with a numerical aperture of 0.95—while obtaining adequate image contrast—indents as small as 14.7 μm in length could be measured. But the challenge is to obtain acceptable image contrast at 1,000× magnification so that the indent tips can be clearly seen. Realistically, a minimum diagonal length of 20 μm is a more realistic limit. These two ASTM standards should eliminate recommending the use of test loads less than 50 gf for Vickers and less than 20 gf for Knoop.

Published: April 2019

Synergistic effects of BRAFV600E and TERT promoter mutations on the poor clinical outcomes in papillary thyroid cancer (PTC) have been demonstrated. The potential mechanism of this phenomenon has been proposed: MAPK pathway activation by the BRAFV600E mutation may upregulate E-twenty six (ETS) transcription factors, increasing TERT expression by binding to the ETS-binding site generated by the TERT promoter mutation; however, it has not yet been fully proven. This article provides transcriptomic insights into the interaction between BRAFV600E and TERT promoter mutations mediated by ETS factors in PTC. RNA sequencing data on 266 PTCs from The Cancer Genome Atlas and 65 PTCs from our institute were analyzed for gene expression changes and related molecular pathways, and the results of transcriptomic analyses were validated by in vitro experiments. TERT mRNA expression was increased by the coexistence of BRAFV600E and TERT promoter mutations (fold change, 16.17; q-value = 7.35 × 10−12 vs no mutation). In the ETS family of transcription factors, ETV1, ETV4 and ETV5 were upregulated by the BRAFV600E/MAPK pathway activation. These BRAFV600E-induced ETS factors selectively bound to the mutant TERT promoter. The molecular pathways activated by BRAFV600E were further augmented by adding the TERT promoter mutation, and the pathways related to immune responses or adhesion molecules were upregulated by TERT expression. The mechanism of the synergistic effect between BRAFV600E and TERT promoter mutations on cancer invasiveness and progression in PTC may be explained by increased TERT expression, which may result from the BRAF-induced upregulation of several ETS transcription factors.
Obesity induces ovarian inflammation and reduces oocyte quality
Authors: Snider Alexandria P , Wood Jennifer R
Published: April 2019

In the United States, 36.5% of women between the ages of 20 and 39 years are obese. This obesity results in not only metabolic disorders including type II diabetes and cardiovascular disease, but also impaired female fertility. Systemic and tissue-specific chronic inflammation and oxidative stress are common characteristics of obesity. This is also true in the ovary. Several studies have demonstrated that pro-inflammatory cytokines and reactive oxygen species alter estrous cyclicity, steroidogenesis and ovulation. Inflammation and oxidative stress also impair meiotic and cytoplasmic maturation of the oocyte which reduces its developmental competence for fertilization and pre-implantation embryo development. Interestingly, there is recent evidence that obesity- and/or polycystic ovary syndrome (PCOS)-dependent changes to the gut microbiome contributes to ovarian inflammation, steroidogenesis and the expression of mRNAs in the oocyte. However, several gaps remain necessitating future studies to identify inflammation, oxidative stress and gut microbiome mechanisms that reduce ovarian function and oocyte quality.
Adolescent and Young Adult Cancer Patients’ Experiences With Treatment Decision-making
Authors: Mack Jennifer W. , Fasciano Karen M. , Block Susan D.
Published: April 2019

BACKGROUND:

Adolescents and young adults (AYAs) with cancer generally want to engage in decision-making but are not always able to do so. We evaluated cancer treatment decision-making among AYAs, including decisional engagement and regret.

METHODS:

We surveyed 203 AYA patients with cancer aged 15 to 29 (response rate 74%) treated at a large academic center and their oncologists. Patients were approached within 6 weeks of diagnosis and asked to report decision-making preferences and experiences (Decisional Roles Scale) and the extent to which they regretted their initial treatment decision (Decisional Regret Scale) assessed at baseline and 4 and 12 months later.

RESULTS:

A majority of AYAs (58%) wanted to share responsibility for decision-making with oncologists; half (51%) preferred limited involvement from parents. Although most AYAs held roles they preferred, those who did not reported holding more passive roles relative to oncologists (P < .0001) and parents (P = .002) than they desired. Nearly one-quarter of patients (24%; 47 of 195) experienced regret about initial cancer treatment decisions at baseline, with similar rates at 4 (23%) and 12 (19%) months. In a multivariable model adjusted for age, decisional roles were not associated with regret; instead, regret was less likely among patients who trusted oncologists completely (odds ratio 0.17 [95% confidence interval 0.06–0.46]; P < .001) and who reported that oncologists understood what was important to them when treatment started (odds ratio 0.13 [95% confidence interval 0.04–0.42]; P < .001).

CONCLUSIONS:

Nearly one-fourth of AYA patients expressed regret about initial treatment decisions. Although some AYAs have unmet needs for decisional engagement, attributes of the patient-oncologist relationship, including trust and mutual understanding, may be most protective against regret.

Listening to Another Italy
Authors: Cosci Marco
Published: April 2019

The transition between the 1950s and 1960s is a watershed moment for the construction of the Italian post-war identity through cinema. Not only do feature films of those years reflect this critical point, but also documentaries become a privileged medium for revealing the contradictions of a country that was increasingly divided between tradition and progress. In this article I focus on the production of composer Egisto Macchi, a leading figure in the renewal of Italian music. He worked with significant filmmakers scoring hundreds of non-fiction films during the 1960s. Combining archival sources with historiographical and theoretical discourses of musicology and film studies, I examine some key examples of Macchi’s soundtracks. Macchi’s scores shun widely encoded musical styles in an attempt to investigate the most striking and hidden character of the reality observed by the camera. On the one hand, experimental music is seen as the best way of engaging afresh with the subject matter; on the other, these documentaries establish a viewpoint and a way of hearing rooted in the contemporary music soundscape.
Looking at the Screen through the Spindle Hole
Authors: Bratus Alessandro
Published: April 2019

The use of songs in Italian cinema could be regarded as a minor issue from a cinematographic perspective, being seen possibly as a derivative by-product in both a film’s production and in its critical reception. However, music plays a crucial role in postwar Italian popular culture, as evidenced by the heated debate about the ideological function of popular and folk music that has raged among intellectuals (most notably Umberto Eco), musicians, ethnomusicologists, and composers. My starting assumption is that a perspective on cinema production gained from the vantage point of the phonographic medium can help to enlighten issues related to changing styles and production practices in Italian popular culture after World War II. Investigating the connections between the film and recording industries also highlights the need for film composers to be versatile and proficient in different genres, a quality that was an integral part of their role as specialized professionals.
Echo-cardiographic parameters for atrial fibrillation in combination with acute coronary syndrome in real clinical practice according to register of acute coronary syndrome in the Krasnodar region
Authors: Tatarintseva Z. G. , Kosmacheva E. D. , Porhanov V. A. , Kruchinova S. V.
Published: April 2019

Aim. To evaluate patients with acute coronary syndrome (ACS) in combination with atrial fibrillation (AF) according to the total register of ACS in the Krasnodar region of echocardiographic (EchoCG) parameters (left atrial dimension (LAD), left ventricular wall thickness (LVWT), left ventricle end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), pulmonary artery systolic pressure (PASP), as well as coronary substrate assessment according to coronary angiography (CAG) and determination of the relationship between the value of LVEF and the coronary substrate.

Material and methods. From the register of the ACS in the Krasnodar region, patients were successively taken to the cardiology departments of Krasnodar regional clinical hospital № 1 for the period from November 20, 2015 to November 20, 2017 with a diagnosis of ACS, accompanied by one of the types of atrial fibrillation. This group of patients was designated as a group of ACS + AF and amounted to 119 patients. The comparison group was selected with the help of a random number generator from patients admitted to the hospital with ACS and intact sinus rhythm (SR) for the period of time from November 20, 2015 to November 20, 2017 (120). We analyzed the ECHO-CG parameters, the coronary substrate — according to the CAG.

Results. When comparing the cohort of patients with ACS + AF with the cohort of patients with ACS + SR, we determined a significant (p<0,05) difference of LA size, LVEF and values of PASP. During comparing the presence of hemodynamically significant stenosis in the coronary arteries we noticed that in ACS + AF patients with LVEF <40% in significantly higher percentage of cases (p=0,0007) occurs significant hemodynamic stenosis of coronary arteries, in contrast to the group of patients with ACS + SR with LVEF <40%. In patients with EF >40% and ACS + SR we determined a significantly more frequent (p<0,001) stenosis.

Conclusion. The results of the analysis are important for understanding the distinguishing characteristics of patients with ACS that occur on the background of AF, which is important for correct prediction of the course of the disease. The maintenance of the ACS register will provide information on the real clinical course of the disease, as well as improve the effectiveness of treatment in real clinical practice.
¿Cirugía estética o amputación?
Authors: Gutiérrez-Velez Edgar , Acero-Plazas Víctor Manuel , Maluk-Duque Fernando , Beltrán-Ríos Karol Bibiana , Roa-Castellanos Ricardo Andrés
Published: April 2019

Propósito: presentar una aproximación histórica, médica y normativa, dentro del contexto colombiano, en torno a la valoración de algunos procedi­mientos quirúrgicos calificados como estéticos. El objetivo es promover la reflexión sobre su conveniencia y aplicabilidad desde el ámbito de la ciencia, teniendo en cuenta los más recientes acontecimientos en relación con la prohibición de estas prácticas.

Descripción: se realizó un análisis de revisión y reflexión sobre esta práctica, frente a los cuestionamientos recientes, frente a elementos puntuales de las técnicas y elmedio cultural en el cual se aplican. Entorno que a su vez está influyendo en la regulación desde el ámbito técnico y científico, en el cual debe predominar la salud y el bienestar animal de los pacientes.

Punto de vista: dentro de la ciencia médica —campo que a su vez es un arte— la cirugía tiene entre sus ramas de especialización a la cirugía plástica, que se subdivide en cirugía cosmética y estética. Se muestra y se discute que el corte de orejas y colas desde la estética no encuentra una justificación técnica científica, a no ser que medie una patología o padecimientoque recomiende su aplicación. Cortar las orejas y las colas puede traer consecuencias irreversibles en los mecanismos de comunicación y expresión de las mascotas.

Conclusiones: antes de realizar cualquier tipo de cirugía estética se debe considerar el bienestar animal y los pros o contras de estos procedimientos.

Emprendimiento e innovación: condición de ciudadanía para los ingenieros del siglo XXI
Authors: Vera Castillo Pedro
Published: April 2019

Es frecuente relacionar el emprendimiento con una necesidad cuando se produce aquella situación —normalmente difícil de enfrentar— de pérdida de un trabajo que veíamos como estable y seguro, las más de las veces de manera inesperada. La creación de un negocio pasa entonces a ser una salida, emprender un negocio aparece como una necesidad. Sin embargo, existe la impresión que todo lo que aprendimos hasta ahora ya no nos sirve para enfrentar esta nueva situación. Esto es así porque nosotros fuimos formados, hace tan solo algunas décadas, cuando existía “un empleo formal y para toda la vida”. Nos formamos entonces con barreras que nos dificultan actuar frente a esta nueva realidad y que nos han dejado prisioneros “mentalmente” del modelo de empleo tradicional. Ellas han sido y continúan siendo reforzadas por nuestros abuelos, padres y familiares y por los maestros a través del sistema educacional. Así, la educación tradicional crea barreras que impiden a los jóvenes avanzar hacia la sociedad que nos espera y nos desafía, entre las cuales están: 1) el estímulo hacia la repetición, 2) la relativización del éxito ajeno, 3) la creencia en el don y 4) la aversión al riesgo. Nos sentimos entonces incapaces de enfrentar esta nueva realidad.
Special issue on alternative reality and analytics for learning:
Authors: González Crespo Rubén , Burgos Daniel
Published: April 2019

One of the main challenges in modern education is to blend formal official learning with a huge variety of content provision, group discussion, self-entrepreneurship, user’s own portfolio, and long lists of possibilities off-the-classroom. Informal learning happens anytime, anywhere. We strongly believe that formal learning does too. The cornerstone is to find the right balance between both contexts. The effective integration of Open Educational Resources with formal lessons, or between traditional lectures and live multi-user conferences, or even more, between spontaneous forum contributions outside the learning management system, and the  official activities towards certification, will make  the difference: the actual change of an educational paradigm. And this could be so for every single shareholder of the educational community, from teachers to tutors, from support staff to managers, from content providers to learning designers and, of course, from students to graduates.

Transformation of memory in post-bipolar world inevitably led to the revival and search (creation) of new individual and collective memory, to the aggravation of attention the memories of witnesses tragedies of the twentieth 143 century – the Holocaust, the Stalinist repressions other ethnic and political genocide. Every country has its own system of «overcoming the past». The politics of memory is one of the important factor in this complicated area of creating of new relationships, which has features in Central and Eastern Europe.
Proximinality and co-proximinality in metric linear spaces
Authors: Narang T. W. , Gupta Sahil
Published: April 2019

As a counterpart to best approximation, the concept of best coapproximation was introduced in normed linear spaces by C. Franchetti and M. Furi in 1972. Subsequently, this study was taken up by many researchers. In this paper, we discuss some results on the existence and uniqueness of best approximation and best coapproximation when the underlying spaces are metric linear spaces.

Authors: Kołodyńska Dorota , Łyko Aleksandra , Gęca Marzena , Hubicki Zbigniew
Published: April 2019

Lately there has been observed the increased presence of chlorates(VII) in the natural environment which can affect human health negatively. Therefore the removal of chlorate(VII) ions using the gel type resin functionalized with the tri-n-butyl ammonium (Dowex™PSR-2) from waters was studied. The main aim was to evaluate the effects of experimental conditions including contact time, initial solution concentration, pH and temperature on chlorate(VII) ions removal as well as the anion exchanger properties on chlorate(VII) ions sorption. It was found that only the pseudo second order model described the experimental data well and the intraparticle diffusion was not the rate-limiting step. According to the Freundlich model, the qe value was to be 69.26 mg/g at optimum conditions (pH 7.0 at 25 oC).

La emigración polaca hacia la Argentina de entreguerras
Authors: Porada Katarzyna
Published: April 2019

El periodo de entreguerras constituye una época destacada en los movimientos poblacionales entre Polonia y Argentina. Se calcula que en dos décadas emigraron a este país latinoamericano aproximadamente 160 mil ciudadanos polacos. La época de entreguerras y particularmente los primeros años de la década de los treinta constituyen también un periodo de gran vulnerabilidad y muy alta desocupación observada entre los inmigrantes polacos, fenómeno especialmente visible en el contexto porteño. Centrándonos en este caso particular, el presente artículo pretende analizar qué consecuencias tuvo el periodo de la crisis económica sobre este grupo, así como la imagen del inmigrante polaco que se fue construyendo en la capital argentina en el periodo señalado.

Czy zagraża nam język popchrześcijaństwa? O nowych zjawiskach w polskim dyskursie religijnym pierwszych dekad XXI wieku
Authors: Zdunkiewicz-Jedynak Dorota
Published: April 2019

Komunikacja religijna nie pozostaje obojętna wobec komercjalizacji i homogenizacji kultury. Realizacji postulatu tzw. nowej ewangelizacji, by zanurzać dyskurs religijny w doświadczeniu człowieka XXI w., powinno towarzyszyć respektowanie ograniczeń w implementowaniu języka, gatunków i ikon popkultury do sfery komunikacji dotyczącej doświadczenia religijnego. W artykule zanalizowano takie wytwory współczesnej katolickiej kultury religijnej, jak internetowe memy ewangelizacyjne oraz przedmioty codziennego użytku (np. akcesoria kuchenne, ubrania), które służą jako nośniki treści religijnych, lub współczesne dewocjonalia i gadżety (np. wypisy biblijne w kształcie Biblii do żucia czy modlitewniki stylizowane na wyroby aptekarskie). Wskazano zagrożenia wynikające z dopasowania dyskursu religijnego do standardów popkulturowych i komercyjnych: uprawianie ewangelizacji w sposób intelektualnie niewymagający i czysto pragmatyczny nie prowadzi do duchowego rozwoju; nie czyni odbiorcy bardziej zdolnym do refleksji religijnej. Właściwa omówionym w artykule gatunkom wypowiedzi i zabiegom ewangelizacyjnym potoczna forma odbiera powagę treści tych przekazów. Umieszczenie treści religijnych w obszarze popkultury i komercji wprawdzie je upowszechnia, ale jednocześnie spłyca i zniekształca ich sens.
Międzykulturowość a sport: mediatyzacja kontaktu kulturowego w doniesieniach prasy brytyjskiej i irlandzkiej na temat Euro 2012
Authors: Wawrzyczek Irmina , Mazur Zbigniew
Published: April 2019

Sport uważa się za uosobienie procesów międzykulturowych dzięki łączeniu ludzi w zgodnych działaniach przy jednoczesnym generowaniu konfliktów między nimi. Ta dwoistość sportu często znajduje odbicie w medialnych sprawozdaniach z imprez sportowych. Niniejszy artykuł przedstawia rezultat badań nad tekstami w prasie brytyjskiej i irlandzkiej poświęconymi finałom Mistrzostw Europy w piłce nożnej (Euro 212) rozgrywanym w Polsce i na Ukrainie, prowadzonych pod kątem ich międzykulturowego oddziaływania. Ton doniesień w gazetach pochodzących z dwu sąsiednich krajów i często należących do tych samych koncernów okazał się bardzo różny. Prasa brytyjska nie dostrzegła obszarów kulturowego zbliżenia między gospodarzami a gośćmi mistrzostw, przyjmując taktykę powielania znanych swoim czytelnikom historycznie utrwalonych stereotypów kulturowego i cywilizacyjnego zacofania Europy Wschodniej. Relacje o kulturowej interakcji Polaków i Irlandczyków zamieszczane w prasie irlandzkiej, choć w większości bardzo pozytywne, także opierały się na stereotypach i banalnych uogólnieniach o obu nacjach. Badanie wykazało, że zarówno doniesienia w prasie brytyjskiej jak i w irlandzkiej rządziły się wewnętrzna logiką i interesami tych mediów, a nie troską o jakość efektów międzykulturowych.
