Background

The correlation between hepatitis B surface antigen (HBsAg) seroconversion and the characteristics of HBV quasispecies (QS) before and during pegylated interferon-α-2a (PEG-IFN-α-2a) treatment in hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) children has not yet been reported.

Methods

35 patients, including 18 HBsAg seroconverters (SS) and 17 non-seroconverters (SN), were enrolled. Serum samples were collected before treatment and at weeks 12 and 24 of treatment. Sequences within the basal core promoter/pre-core (BCP/PC) and S/reverse transcriptase (S/RT) region were analysed by next-generation sequencing.

Results

There was no significant difference in the baseline diversity of HBV QS (Shannon entropy [Sn]; Hamming distance [HD]) in either region between the two groups. The baseline mutations A1762T/G1764A, C1913A, and T2003A/G or C2004T were correlated with non-response to therapy ( P=0.025, P=0.036, P=0.032, respectively). After 24 weeks of therapy, HBV diversity within the BCP/PC region in the SS group notably declined (Sn: P=0.002; HD: P=0.011), while that of the SN group was nearly unchanged. As for the S/RT region, 24 weeks of treatment made no significant difference on QS diversity in either group.

Conclusions

Our data demonstrated that the baseline viral mutations and dynamic changes in HBV QS diversity within the BCP/PC region were closely related to HBsAg seroconversion in HBeAg-positive CHB children treated with PEG-IFN-α-2a.
Resolving “orphaned” non-specific structures using machine learning and natural language processing methods

Published: August 2018

Scholarly publications of biodiversity literature contain a vast amount of information in human readable format. The detailed morphological descriptions in these publications contain rich information that can be extracted to facilitate analysis and computational biology research. However, the idiosyncrasies of morphological descriptions still pose a number of challenges to machines. In this work, we demonstrate the use of two different approaches to resolve meronym (i.e. part-of) relations between anatomical parts and their anchor organs, including a syntactic rule-based approach and a SVM-based (support vector machine) method. Both methods made use of domain ontologies. We compared the two approaches with two other baseline methods and the evaluation results show the syntactic methods (92.1% F1 score) outperformed the SVM methods (80.7% F1 score) and the part-of ontologies were valuable knowledge sources for the task. It is notable that the mistakes made by the two approaches rarely overlapped. Additional tests will be conducted on the development version of the Explorer of Taxon Concepts toolkit before we make the functionality publicly available. Meanwhile, we will further investigate and leverage the complementary nature of the two approaches to further drive down the error rate, as in practical application, even a 1% error rate could lead to hundreds of errors.
Disorders of the immune status in patients with chronic cerebral ischemia; differentiated pharmacological correction
Authors: Shulginova Anastasiya A. , Konoplya Alexander I. , Bystrova Natalya A.
Published: August 2018

Introduction: Chronic cerebral ischemia (CCI) accounts for 60-75% of all cerebrovascular diseases in Russia and around the world. The problem: the issues concerning the role of immunity in the pathogenesis of CCI depending on the main etiologic factor and stage of the disease are hardly elaborated, which makes the main pharmacological correction impossible. The objective of the study is to establish the immune disorder patterns in patients with CCI I-II associated with arterial hypertension and to develop differentiated pharmacological methods for their correction.

Material and methods: The results of treatment of 104 patients of Kursk Regional Clinical Hospital with CCI associated with II-stage arterial hypertension were analyzed: 52 patients were with CCI I stage (2th-4th groups of 12-14 patients) and 52 patients were with CCI II stage (5th -7th groups of 12-14 patients), aged 50±5, who received the basic pharmacological therapy (enalapril and vinpocetine). The patients of the 2nd and 5th groups additionally received ceraxon and mexicor, those of the 3rd and the 6th groups additionally received immunomodulator glutoxim, and those from the 4th and 7th groups received polyoxidonium. Twenty-two healthy donors were in the control group. Immune disorders were assessed by the parameters of the functional activity of neutrophils, levels of cytokines in plasma, components of the complement and inhibitors.

Results and discussion: In the case of CCI I and II stages similar proinflamatory immune disorders were detected, which is indicative of immune inflammation. The inclusion of glutoxime and polyoxidonium in a complex pharmacotherapy helps reduce the severity of immune and neuropsychic status indicators, which are more evident in case of stage II.

Conclusions: In case of CCI I stage, the medications used can be arranged according to their clinico-immunological efficacy in ascending order: ceraxon+mexicore ® ceraxon+mexicor+glutoxim ® ceraxon+mexicor+polyoxidonium, and in case of CCI II stage: ceraxon+mexicor ® ceraxon+mexicor+polyoxidonium = ceraxon+mexicor+glutoxim.

Published: August 2018

The substantial morbidity and mortality caused by invasive fungal pathogens, including Cryptococcus neoformans, necessitates increased understanding of protective immune responses against these infections. Our previous work using murine models of cryptococcal lung infection demonstrated that dendritic cells (DCs) orchestrate critical transitions from innate to adaptive immunity and that IL-10 signaling blockade improves fungal clearance. To further understand interrelationships among IL-10 production, fungal clearance, and the effect of IL-10 on lung DCs, we performed a comparative temporal analysis of cryptococcal lung infection in wild type C57BL/6J mice (designated IL-10+/+) and IL-10−/− mice inoculated intratracheally with C. neoformans (strain 52D). Early and sustained IL-10 production by lung leukocytes was associated with persistent infection in IL-10+/+ mice, whereas fungal clearance was improved in IL-10−/− mice during the late adaptive phase of infection. Numbers of monocyte-derived DCs, T cells, and alveolar and exudate macrophages were increased in lungs of IL-10−/− versus IL-10+/+ mice concurrent with evidence of enhanced DC type-1, Th1/Th17 CD4 cell, and classical macrophage activation. Bone marrow–derived DCs stimulated with cryptococcal mannoproteins, a component of the fungal capsule, upregulated expression of IL-10 and IL-10R, which promoted DC type-2 activation in an autocrine manner. Thus, our findings implicate fungus-triggered autocrine IL-10 signaling and DC type-2 activation as important contributors to the development of nonprotective immune effector responses, which characterize persistent cryptococcal lung infection. Collectively, this study informs and strengthens the rationale for IL-10 signaling blockade as a novel treatment for fungal infections.

Ischemic myocardial injury results in sterile cardiac inflammation that leads to tissue repair, two processes controlled by mononuclear phagocytes. Despite global burden of cardiovascular diseases, we do not understand the functional contribution to pathogenesis of specific cardiac mononuclear phagocyte lineages, in particular dendritic cells. To address this limitation, we used detailed lineage tracing and genetic studies to identify bona fide murine and human CD103+ conventional dendritic cell (cDC)1s, CD11b+ cDC2s, and plasmacytoid DCs (pDCs) in the heart of normal mice and immunocompromised NSG mice reconstituted with human CD34+ cells, respectively. After myocardial infarction (MI), the specific depletion of cDCs, but not pDCs, improved cardiac function and prevented adverse cardiac remodeling. Our results showed that fractional shortening measured after MI was not influenced by the absence of pDCs. Interestingly, however, depletion of cDCs significantly improved reduction in fractional shortening. Moreover, fibrosis and cell areas were reduced in infarcted zones. This correlated with reduced numbers of cardiac macrophages, neutrophils, and T cells, indicating a blunted inflammatory response. Accordingly, mRNA levels of proinflammatory cytokines IL-1β and IFN-γ were reduced. Collectively, our results demonstrate the unequivocal pathological role of cDCs following MI.

Published: August 2018

A long-term study implemented in the Amur River basin enabled us to generate an updated checklist of 606 valid species in Chironomidae (Diptera) which are composed of 129 genera and six subfamilies, with 98 (17%) described new species belonging to 46 genera. Among the 98 recently described species, 46 ones (45%), were considered as possible endemics and sub-endemics. The numbers of species and genera by subfamilies is as follows: Podonominae (3 species; 3 genera), Tanypodinae (17; 9), Diamesinae (25; 11), Prodiamesinae (7; 3), Orthocladiinae (307; 57) and Chironominae (247; 46). The higher numbers of species (421 and 410, respectively) were recorded in the Lower and Middle parts of the Amur River basin, as compared with the Upper part of the basin. Most of the recorded chironomids (387 species, 67%) are Palaearctic in distribution, while others (191, 33%) are widely Holarctic. Species with Palaearctic distribution mostly have the following range types: East Palaearctic continental (23%); East Palaearctic continental-insular (20%); Palaearctic transpalaearctic (14%); Palaearctic amphi-Eurasian (10%).
Drainage ditches as important habitat for species diversity and rare species of aquatic beetles in agricultural landscapes (Insecta: Coleoptera)
Authors: Rolke Daniel , Jaenicke Birgit , Pfaender Jobst , Rothe Udo
Published: August 2018

Agricultural drainage ditches are common structures in cultivated lowland areas across Europe. These artificial linear water bodies are interconnected to form networks that can offer valuable habitats for many water associated organisms. The current study contributes to the knowledge of aquatic Coleoptera biodiversity associated with artificial drainage ditches. Fundamental ecological and faunistical findings were combined with aspects relevant for applied nature conservation. Adult beetles were sampled at 124 sampling locations belonging to seven study sites in the federal state of Brandenburg, Germany. With 108 taxa out of 10 families the studied ditches showed a high species richness. Taxa associated with eutrophic conditions dominated with the dytiscid Hydroporus palustris as the most abundant species. In terms of β-diversity, a moderate turnover between the study sites could be observed. Although the sampling locations showed some degree of variability concerning habitat characteristics, measured environmental parameters only weakly explained observed differences in community composition. Beside taxonomical characterization of beetle diversity, aspects of functional diversity were analyzed. Interestingly, individuals with reduced flight ability were dominant. Because the predaceous family Dytiscidae dominated, beetles were mainly integrated as carnivores in the food web of ditches. Throughout the study, 13.0% threatened as well as 18.4% rare taxa could be recorded, referring to the German fauna of aquatic beetles. This may underpin the need to include agricultural drainage ditches into conservation management.
Access to, use and challenges of ICTs in secondary schools in Tanzania: a study of selected secondary schools in Morogoro Municipality
Authors: Malekani Andrew A.
Published: August 2018

This study was conducted to establish current status of ICTs in terms of access, use and challenges of ICTs in selected secondary schools in Morogoro municipality. The study was a cross section survey and used self administered questionnaires that were given to teachers and students in selected schools. This was supplemented by observations and secondary data review. 20 teachers and 60 students were involved in the study. The findings indicated that the status of ICTs is not good in secondary schools. Though students and teachers seem to be aware of ICTs, but the schools have no enough facilities for ICTs and the facilities available are not adequately utilized. Moreover, the teachers reported that they have no in-service training related to ICTs in teaching and learning. It was also reported that low band width (resulting into poor internet connectivity or slow speed), lack of standby power, and lack of a policy and training schedule hindered the utilization of ICTs in the selected schools. It is recommended that to effectively introduce and efficiently utilize these emerging technologies, remedies should be made to overcome the stated challenges.Keywords: ICTs, Improved learning, secondary schools, Morogoro
Parentalidades intensivas y éticas del cuidado: Discursos de niños(as) y adultos de estrato bajo de Santiago
Authors: Vergara del Solar Ana C. , Sepúlveda Galeas Mauricio A. , Chávez Ibarra Paulina B.
Published: August 2018

Las parentalidades desplegadas en los sectores más pobres han sido, históricamente, objeto de sospecha de parte del Estado y de la sociedad en general. Este artículo describe los resultados relativos al estrato socioeconómico bajo de una investigación orientada a comprender los discursos de niños y adultos acerca de la relación padres e hijos en Chile hoy. La investigación se basa en los Estudios Sociales de la Infancia, en los Estudios sobre Culturas Parentales, y el Análisis Crítico de Discursos, y fue desarrollada a través de entrevistas grupales abiertas y semiestructuradas. Los niños muestran a la parentalidad como una tarea sacrificial y solitaria, y dan cuenta de una búsqueda de formas de aliviar las vidas de sus padres; los padres, por su parte, enfatizan la temática de una presencia permanente, además de intentar contrarrestar los estereotipos que presentan a las parentalidades de sectores pobres como violentas o negligentes. En las conclusiones se destaca el carácter recíproco del cuidado entre padres e hijos, así como la intensificación de las demandas relacionadas con la parentalidades y la condición de ser hijos en contextos neoliberales, y se relacionan estos aspectos con las condiciones de existencia del estrato bajo.
De la participación adultocéntrica a la disidente: La otra participación infantil
Authors: Lay-Lisboa Siu , Montañés Serrano Manuel
Published: August 2018

Esta investigación se enmarca en el enfoque teórico de los nuevos estudios de la infancia, que considera a las niñas y niños sujetos sociales capaces de ofrecer su versión de la realidad social, así como reflexionar y teorizar sobre ella y no meros objetos de estudio. El propósito de la misma fue el conocer cómo la infancia concibe y construye su participación. De acuerdo con una metodología cualitativa, se realizaron diez grupos de discusión, en los que participaron 70 niñas y niños chilenos de entre 10 y 14 años, de diversos centros educativos y lugares del país. El análisis de los discursos dio cuenta de siete posiciones discursivas sobre la participación infantil, que se engloban en una participación adultocentrada, que es la dominante, y en otra disidente de ésta, que deconstruye los metarrelatos hegemónicos, posicionándose a favor de una participación infantil alternativa, más democrática, creativa e inclusiva.

En los últimos años, a propósito de las transformaciones en las representaciones de la infancia en Chile y en el mundo, la historia reciente ha abierto un espacio, en los estudios sobre las dictaduras cívico-militares del cono sur, para investigar a través de distintas fuentes la experiencia de la niñez desde la mirada de sus protagonistas. En este artículo de investigación se presentan resultados en torno a los recuerdos de personas que vivieron su niñez durante la última dictadura cívico-militar chilena, específicamente en torno a los recuerdos de infancia y familia.  A través del análisis de dos fuentes: 1) objetos creados por niñas y niños entre 1973-1990 (cartas, dibujos, tarjetas, diarios de vida, etc.); y 2) relatos construidos a partir de entrevistas realizadas durante el 2015-2016 a adultos que vivieron dicha etapa histórica, a través de la evocación que produjo el encuentro con los objetos mencionados en el punto 1 y que las personas donaron para la construcción de un archivo patrimonial. En los resultados se reflexiona acerca del impacto de la violencia en la reorganización o ruptura de los lazos familiares consanguíneos,  la percepción sobre la infancia vivida, la represión y el papel de la familia exogámica y política.
Derechos del niño y sistemas residenciales en Chile: Representaciones sociales de adultos cuidadores

Published: August 2018

El paradigma de niños y niñas en situación irregular ha sido la cosmovisión orientadora en la construcción de las representaciones de la infancia durante más de dos siglos. Este artículo aborda las representaciones sociales sobre los derechos del niño de adultos/as que se desempeñan en el rol cuidadores/as en residencias del Servicio Nacional de Menores en Chile (SENAME). La investigación fue de tipo cualitativa, aplicando entrevistas semiestructuradas como técnica de producción de datos a diez cuidadores/as de la región de Ñuble. Las representaciones de los cuidadores/as se presentan mediante dos núcleos figurativos: relativo al niño/a y relativo al cuidador/a. Los principales hallazgos muestran un universo semántico donde coexiste la nueva visión del niño como sujeto de derechos junto a la imagen de un niño como objeto de protección. El cuidador/a ancla su identidad sobre el ejercicio de los cuidados, definiendo un marco de relación con el niño donde imperan conductas tradicionales de cuidado (satisfacción de necesidades básicas), con el desarrollo de conductas bien tratantes ligadas a valores, reconocimiento del otro/a, expresión emocional y fuerte componente afectivo. Asimismo, se devela una alteridad en tensión respecto de un niño concebido, por una parte, como sujeto de derechos, pero, por otra parte, como desafiante y en ocasiones poco colaborativo.

Los nuevos discursos sociales vinculados al enfoque derechos, las nuevas sensibilidades epocales respecto a la niñez o ciertas lecturas críticas de la noción de minoría de edad han impactado la producción científica. Durante los últimos años se han visto incrementadas las investigaciones en Ciencias Sociales enmarcadas desde paradigmas novedosos. Muchas de ellas han consensuado la necesidad de estudiar la infancia desde sus propias perspectivas, así como desde una mirada crítica y compleja especialmente cuando se trata de abordar las temáticas que los afectan directamente, desde una posicionalidad ético-política que insiste en integrar sus voces silenciadas históricamente. A través de 14 artículos provenientes de diversos ámbitos disciplinarios como geográficos que buscan complejizar las miradas y las metodologías para abordar una investigación sobre y desde la infancia históricamente situada y éticamente responsable. Todos ellos buscan cumplir con el propósito de evidenciar la multiplicidad de conocimientos sobre los modos de producción de subjetividades infantiles, las tensiones y disputas que emergen en su definición y en sus modos de intervenir en ámbitos claves como la educación, la salud mental, la familia, la política, los territorios, la guerra, las instituciones, entre otros; y  visibilizar la producción de conocimientos desde los propios discursos infantiles y adolescentes en temas de parentalidad, bienestar infantil, participación y escuela.
Methane and ethane emission scenarios for potential shale gas production in Europe
Authors: Visschedijk Antoon J. H. , Denier van der Gon Hugo A. C. , Doornenbal Hans C. , Cremonese Lorenzo
Published: August 2018

Abstract. A main concern surrounding (shale) gas production and exploitation is the leakage of methane, a potent greenhouse gas. High leakage rates have been observed outside of Europe but the representativeness of these observations for Europe is unknown. To facilitate the monitoring of methane leakage from a future shale gas industry in Europe we developed potential production scenarios for ten major shale gas plays and identified a suitable tracer in (shale) gas to distinguish oil and gas related emissions from other methane sources. To distinguish gas leakage from other methane sources we propose ethane, a known tracer for leakage from oil and gas production but absent in emissions from other important methane sources in Europe. Ethane contents for the ten plays are estimated from a European gas composition database and shale gas composition and reservoir data from the US, resulting in three different classes of ethane to methane ratios in the raw gas (0.015, 0.04 and 0.1). The ethane content classes have a relation with the average thermal maturity, a basic shale gas reservoir characteristic, which is known for all ten European shale gas plays. By assuming different production scenarios in addition to a range of possible gas leakage rates, we estimate potential ethane tracer release by shale gas play. Ethane emissions are estimated by play following a low, medium or high gas production scenario in combination with leakage rates ranging from 0.2 %–10 % based on observed leakage rates in the US.
Joint retrieval of surface reflectance and aerosol properties with continuous variation of the state variables in the solution space: Part 2: Application to geostationary and polar orbiting satellite observations
Authors: Luffarelli Marta , Govaerts Yves
Published: August 2018

Abstract. This paper presents the Aerosol Optical Thickness and surface properties simultaneous retrieval from the CISAR algorithm applied both to geostationary and polar orbiting satellite observations. The theoretical concepts of the CISAR algorithm have been described in Govaerts and Luffarelli (2017). This paper aims to demonstrate CISAR applicability to actual satellite data acquired from different sensors flying on different orbits. For that purpose, CISAR has been applied to SEVIRI and PROBA-V observations acquired over 20 AERONET stations during year 2015. CISAR retrieval from the two instrument observations is evaluated against independent datasets such as MODIS land product and AERONET data. The performance differences resulting from the two types of orbit are discussed, analysing and comparing the information content of SEVIRI and PROBA-V observations.

Abstract. Versions 6 and 7 of the UK Global Ocean configuration (known as GO6 and GO7)
will form the ocean components of the Met Office GC3.1 coupled model and
UKESM1 earth system model to be used in CMIP61 simulations. The
label “GO6” refers to a traceable hierarchy of three model configurations
at nominal 1, 1∕4 and 1/12∘ resolutions. The GO6 configurations
are described in detail with particular focus on aspects which have been
updated since the previous version (GO5). Results of 30-year forced ocean-ice
integrations with the 1/4∘ model are presented, in which GO6 is
coupled to the GSI8.1 sea ice configuration and forced with
CORE22 fluxes. GO6-GSI8.1 shows an overall improved
simulation compared to GO5-GSI5.0, especially in the Southern Ocean where
there are more realistic summertime mixed layer depths, a reduced
near-surface warm and saline biases, and an improved simulation of sea ice.
The main drivers of the improvements in the Southern Ocean simulation are
tuning of the vertical and isopycnal mixing parameters. Selected results from
the full hierarchy of three resolutions are shown. Although the same forcing
is applied, the three models show large-scale differences in the near-surface
circulation and in the short-term adjustment of the overturning circulation.
The GO7 configuration is identical to the GO6 1/4∘ configuration
except that the cavities under the ice shelves are opened. Opening the ice
shelf cavities has a local impact on temperature and salinity biases on the
Antarctic shelf with some improvement in the biases in the Weddell Sea.
Intraseasonal summer rainfall variability over China in the MetUM GA6 and GC2 configurations

Published: August 2018

Abstract. The simulation of intraseasonal precipitation variability over China in extended
summer (May–October) is evaluated based on six climate simulations of the
Met Office Unified Model. Two simulations use the Global Atmosphere 6.0 (GA6)
and four the Global Coupled 2.0 (GC2) configuration. Model biases are large
such that mean precipitation and intraseasonal variability reach twice their
observed values, particularly in southern China. To test the impact of
air–sea coupling and horizontal resolution, GA6 and GC2 at horizontal
resolutions corresponding to ∼25, 60, and 135 km at 50∘ N are
analyzed. Increasing the horizontal resolution and adding air–sea coupling
have little effect on these biases. Pre-monsoon rainfall in the Yangtze River
basin is too strong in all simulations. Simulated rainfall amounts in June
are too high along the southern coast and persist in the coastal region
through July, with only a weak northward progression. The observed northward
propagation of the Meiyu–Baiu–Changma rainband from spring to late summer
is poor in all GA6 and GC2 simulations. To assess how well the MetUM
simulates spatial patterns of temporally coherent precipitation, empirical
orthogonal teleconnection (EOT) analysis is applied to pentad-mean
precipitation. Patterns are connected to large-scale processes by regressing
atmospheric fields onto the EOT pentad time series. Most observed patterns of
intraseasonal rainfall variability are found in all simulations, including
the associated observed mechanisms. This suggests that GA6 and GC2 may
provide useful predictions of summer intraseasonal variability despite their
substantial biases in mean precipitation and overall intraseasonal variance.
Modeling Error Learning based Post-Processor Framework for Hydrologic Models Accuracy Improvement

Published: August 2018

Abstract. This paper studies how to improve the accuracy of hydrologic models using machine learning models as post-processors and presents possibilities to reduce the workload to create an accurate hydrologic model by removing the calibration step. It is often challenging to develop an accurate hydrologic model, due to the time-consuming model calibration procedure and the non-stationarity of hydrologic data. Our findings show that the errors of hydrologic models are correlated with model inputs. Thus motivated, we propose a modeling error learning based post-processor framework by leveraging this correlation to improve the accuracy of a hydrologic model. The key idea is to predict the differences (errors) between the observed values and the hydrologic model predictions by using machine learning techniques. To tackle the non-stationarity issue of hydrologic data, a moving window based machine learning approach is proposed to enhance the machine learning error predictions by identifying the local stationarity of the data using a stationarity measure developed based on Hilbert-Huang transform. Two hydrologic models, the Precipitation-Runoff Modeling System (PRMS) and the Hydrologic Modeling System (HEC-HMS), are used to evaluate the proposed framework. Two case studies are provided to exhibit the improved performance over the original model using multiple statistical metrics.
CS unplugged in higher education
Authors: Kovácsné Pusztai Kinga
Published: August 2018

Nowadays, there is a significant lack of workforce in the IT industry, even though it is one of the most lucrative professions. According to researchers' forecasts, the existing shortage is growing, so the wages offered will be higher, yet it seems that young people are not attracted to the profession. This problem draws attention to the need to change the curriculum so that it can attract students more. One possible solution is to supplement the curriculum with CS Unplugged activities, which makes it easier to understand and deepen difficult concepts and make IT lessons more colorful. In my article, besides presenting the already known CS Unplugged activities, I will deal with how this can be applied in Hungarian higher education as well.
Successors’ Characteristics, Preparation, Innovation, and Firm Performance: Taiwan and Japan
Authors: Liu Jeng
Published: August 2018

Recent research has revisited business succession. Although important issues have been discussed from time to time, no consensus on any particular pattern of succession has emerged. Lacking a body of empirical findings to draw upon, discussions of business succession are often based on limited qualitative case studies and findings vary widely among researchers. In this research, we focus on both theoretical explanations and data promotion, and draw the following conclusions.First, there are some differences in the corporate culture and business philosophy between Taiwanese and Japanese enterprises, and the training of successors is also different. Second, the number of female successors has been increasing in both Taiwan and Japan, while in Taiwan female successors have become even more open and innovative than their male counterparts. Third, successors in Taiwan and Japan make various kinds of preparations. The successors are expected to start from the front-line to win the loyalty of employees and managers, to keep in touch with front-line employees, to learn the enterprise’s operating mode, and to think about a future development strategy. Fourth, the grown-up environment of the successor also plays an important role and has a great influence on the successor.  Last, but not least, many well-known disputes have occurred in the enterprise succession process both in Taiwan and Japan, and the support provided by the previous generation and the “veterans” will make the succession process go smoothly.
“Mary has filled me with amazement that she gave milk to the One who feeds the multitudes”: Notes on the Byzantine Iconography of Maria Galaktotrophousa
Authors: Smorąg-Różycka Małgorzata
Published: August 2018

The image of the Virgin Mary breastfeeding the Christ Child belongs to the most fascinating and yet least researched themes of Byzantine Marian iconography. In the past it has been assumed that the images of the Virgin Galaktotrophousa derived from the art of the Italian Duecento and Trecento in the post-Byzantine period. However, there is sufficient ground to assume that these images were known already in the Middle Byzantine period and were popular during the period of the Paleologian dynasty.
The Image of the Lithuanian and Ruthenian Legacy of the Jagiellons in 16th-Century Pictorial Catalogues of Polish Monarchs
Authors: Mroziewicz Karolina
Published: August 2018

This article analyses the dynamics that were present in the manner of representing the Lithuanian and Ruthenian legacy of Ladislaus Jagiello and of the first two generations of his descendants in popular 16th-century pictorial catalogues of Polish monarchs. The catalogues actively supported the collective memory and facilitated the integration of Lithuanian and Ruthenian traditions in the Kingdom of Poland. An analysis of the textual and visual message of Maciej of Miechów’s Chronica Polonorum (1519, 1521), of the treatises by Justus Decius appended to it in 1521, the illustrated chronicles of Marcin (1551, 1554, 1564) and Joachim (1597) Bielski, and the visual contents of Tomasz Treter’s Regum Poloniae icones (1591) series has shown that a typical feature of 16th-century works on the first Jagiellons is the non-uniformity of their literary narrations, which contrasts with the relatively stable image of the Jagiellons in the pictorial catalogues. The textual narratives were much quicker to react to the current political, cultural and confessional needs than their visual counterparts, and they accordingly adjusted the literary image of the first Jagiellons. In the dynastic narrations the unfavourable image of the Jagiellons, still present in the first two decades of the 16th century, was replaced by a laudatory narrative concerning the predecessors of Sigismund the Old, which brought into prominence the dynasty’s ancient lineage and its contributions to the Kingdom of Poland. The Eastern roots of the Jagiellons were assimilated into the Polish historical representations by crediting the Lithuanians and Ruthenians with a  Sarmatian genealogy. The narratives of the nobility dating from the second half of the 16th century associated the dynasty’s history with that of the nobility and presented it in the light of the religious, heraldic and socio-ethical interests of Polish noblemen. Ladislaus Jagiello was therefore depicted as a leader of the Polish and Lithuanian nations, operating at the intersection of two diverse cultures, i.e. cultures which were not subject to any evaluative assessment unless they were detrimental to Polish traditions and interests. The last discussed pictorial catalogue, i.e. a  series of depictions of monarchs by Tomasz Treter, is a rare example of reaching back to Jagiello’s Eastern heritage by choosing a Ruthenian painting as a model for his depiction. The use of a Ruthenian representation of the king from all the paintings funded by Jagiello is proof of interest in the Eastern artistic tradition and of its gradual integration into the cultural heritage of the Crown on the eve of the Union of Brest (1596).
Tecendo memórias e ausências: Autobiografia como matéria da arte
Authors:   Universidade Estadual do Paraná, Vaz Rita Isabel , Panek Bernadette Maria ,   Universidade Estadual do Paraná
Published: August 2018

Este artigo buscou compreender a autobiografia como matéria da arte tendo como referência os artistas Louise Bourgeois, Frida Kahlo e José Leonilson. Bourgeois transforma suas memórias, perdas e traumas em arte. Kahlo dribla a dor, expressa sua paixão pela vida. Leonilson enfrenta a proximidade da morte. Encontrei conexão com estes artistas cujas vidas e obras se confundem. O procedimento metodológico parte da investigação teórica e do trabalho prático em relação dialética ao longo de todo o processo. De Gaston Bachelard, interessa o conceito de casa/corpo, como lugar da dimensão onírica da recordação. Philippe Lejeune discute autobiografia e a escrita de diário com a função de conservar a memória. E Georges Didi-Huberman trata a ausência como presença, vestígio, e a pele como lugar dos sinais tanto do envelhecimento/memória quanto do desejo/toque. Resultaram desse processo três obras que se conectam aos artistas elencados e aos conceitos trazidos pelos teóricos, e evidenciam o uso da memória, da autobiografia e das ausências como expressão singular.

Homo Fragilis: Lygia Clark e as confissões heterotanatográficas
Authors:   Fundação Universidade Federal do Rio Grande, De Martino Marlen
Published: August 2018

Esse artigo propõe realizar uma reflexão acerca da Estruturação do Self, criada por Lygia Clark a partir do que Juliano Garcia Pessanha denomina como heterotanatografia, uma fala confessional na qual pequenas e grandes mortes são impressas no registro das narrativas. Parece haver um longo legado transmitido por Lygia Clark ao antecipar obras de artistas contemporâneas como Ana Teixeira, Beth Moysés e Isabela Sielski que tematizam a memória e as confissões heterotanatográficas na década de noventa.
O dispositivo videográfico e as narrativas de si mesmo e do outro: Videocorpo
Authors:   Universidade Estadual Paulista, Sarzi-Ribeiro Regilene Aparecida
Published: August 2018

Apresentamos este artigo sobre as narrativas de si mesmo e do outro por meio do estudo do vídeo Entre de Nina Galanternick. Partindo do argumento de que o corpo que performa para a câmera atua como um operador de sentido do dispositivo videográfico e que o sincretismo corpo-máquina age como protagonista da construção de identidade entre os sujeitos, buscamos aproximar o vídeo das ideias de programação e dispositivo, para defendê-lo como elemento performático, para além de um meio de registro ou documentação. Para fundamentação teórica optamos pelos autores Gilles Deleuze, Giorgio Agamben e Vilém Flusser e seus estudos sobre dispositivos e técno-imagens, Hans Belting e a relação entre corpo e imagem e Arlindo Machado e a arte do vídeo brasileiro. Conhecer as relações entre visibilidade e interação, corpo e vídeo, arte performática e linguagem videográfica nos permitiu compreender como se constroem o sentido da vida, das relações entre os corpos e as narrativas de si mesmo e do outro.
Rupturas identitárias na produção artística de Cindy Sherman e Yasumasa Morimura
Authors:   Universidade Federal de Santa Maria, Selistre Jacks Ricardo , Blanca Rosa María ,   Universidade Federal de Santa Maria
Published: August 2018

Este artigo propõe uma análise queer das produções artísticas de Cindy Sherman e Yasumasa Morimura a fim de problematizar a inexistência de um sujeito original e único na contemporaneidade. A abordagem queer permite desconstruir identidades fixas, proporcionando leituras plurais às obras de arte. Sherman e Morimura se apresentam como sujeitos instáveis, transformáveis e com identidades efêmeras, de modo que desestabilizam o sistema clássico de identificação. Nas suas produções os sujeitos se instalam no devir (des)identitário, (des)construindo-se constantemente. Através das produções de Sherman a linguagem do autorretrato é problematizada, questionando quais métodos de exposição do sujeito são possíveis para o autorretrato na arte contemporânea. Os sujeitos são problematizados na obra de Morimura através da estética camp que se alia ao exagero e à imitação, questionando a fixidez identitária e os processos naturais de construção dos sujeitos.
A supressão do outro no episódio do Queermuseu: A liberdade de expressão sob coerção e o que pode o artivismo queer
Authors:   Centro Universitário de Brusque, Zen Rafael Luiz
Published: August 2018

A partir do fechamento da mostra Queermuseu em 2017, foram percebidas estratégias de manipulação neofundamentalistas que dessubjetivam a expressão individual do discurso artístico queer. Fala-se da liberdade da fala e das tentativas de apagamento do sujeito porque se admite como objetivo principal debater a supressão do outro a partir de uma coerção discursiva que fere a liberdade de expressão. Como objetivos secundários, tem-se: promover a discussão teórica da liberdade de expressão; revelar na linguagem um local de fogo através do discurso artístico; e analisar as obras de Bia Leite, expostas na mostra. Metodologicamente, foram feitas pesquisas bibliográficas, posteriormente correlacionadas com o estudo de caso das obras de Leite. Ao final, percebe-se que, ao abordar o tema da cartografia das diferenças, este estudo encara o artivismo como uma ferramenta discursiva das lutas sociopolíticas, reafirmando a importância da resistência.
Corpographies: Explorations du corps face au politique
Authors:   Institución Universitaria Bellas Artes y Ciencias de Bolívar, Amorocho Martha Liliana
Published: August 2018

Empruntée à la pensée de la décolonisation, la conception du corps comme territoire continue, encore aujourd’hui – et avec force, à servir de lieu de contestation pour des artistes femmes en Amérique latine. Nous le découvrons à travers l’analyse des œuvres photographiques et performatives des artistes que nous avons choisies d’étudier. Celles-ci réussissent à créer une écriture du corps aussi bien par sa fragmentation et son déchiffrement que par son utilisation comme support tant d’un imaginaire érotique que d’une prise de position politique et sociale. Les œuvres analysées composent des phrases transgressives qui transforment la matérialité du corps en signe, en décrivent les paysages intimes, en érigent des cartographies et en déjouent les frontières. Instituant l’image en prise de parole contre la violence, le féminicide, l’extractivisme et la domination en vue d’une ré-appropriation du corps, elles mettent le doigt dans le vif d’une réalité sociale encore trop présente nous concernant tous.

Paisagens descritivas: O registro de lugares possíveis na obra de Frans Post (1612-1680)
Authors:   Universidade Federal do Rio Grande do Sul, Schröpel Daiana
Published: August 2018

O presente artigo analisa três obras do artista holandês Frans Post (1612-1680), integrante da missão científica trazida pelo Conde Maurício de Nassau ao Brasil no século XVII. As obras – designadas O Rio São Francisco (1638), Forte Maurício no Rio São Francisco (1647) e Cachoeira de Paulo Afonso (1647) – são abordadas, simultaneamente, sob perspectiva científica e como representações pictóricas. Desenvolve-se a noção lugares possíveis, conforme proposta por Svetlana Alpers (1987), para a compreensão das imagens criadas por Post in loco em situação de artista viajante e, posteriormente, das representações criadas a partir do repertório de formas, constituído ao longo de sua estadia no Brasil. Pretende-se, desse modo, alargar o entendimento sobre a obra daquele artista, conservando seu duplo estatuto, a saber, como registros visuais descritivos e como imagens construídas entre realidade e artifício.

Authors: Egea Jiménez Carmen , A. Fabre Platas Danú
Published: August 2018

RESUMENEl trabajo analiza cómo se construye socialmente un espacio público usado por jóvenes, el botellódromo de Granada. Para el análisis se usa: bibliografía, noticias de prensa y entrevistas a jóvenes que frecuentan este espacio. Los resultados señalan, por un lado, que los medios de comunicación (españoles) inciden en los aspectos más negativos y a veces “criminalizante” de la actividad; y, por otro, que para los jóvenes significa un ritual de paso en el inicio de una etapa de vida adulta y universitaria a través del ocio.Palabras clave: espacio público; jóvenes; botellódromo. ABSTRACTThis article analyzes the social construction of a public space, located in the city of Granada and frequented mainly by young people: the “botellódromo”. The main sources and tools of the research were the bibliographic and hemerographic survey and interviews with the regulars. The results indicate that the Spanish media highlight the most negative and sometimes “criminalizing” aspects of the activity. On the other hand, for the young people, attendance at this place means a ritual of passage to adulthood and university life, through leisure.Keywords: public space; youth; “bottellódromo”.
