Authors: Janavicius Mantas , Lachej Nadezda , Anglickiene Giedre , Vincerzevskiene Ieva , Brasiuniene Birute
Published: November 2020

Background. Historically, melanoma with brain metastases has a poor prognosis. In this retrospective medical record review, we report basic clinicopathological parameters and the outcomes of patients with melanoma and brain metastases treated with different treatment modalities before the era of immunotherapy and modern radiotherapy technique. Methods. Patients with metastatic melanoma were treated with surgery, radiotherapy, and/or systemic therapy from 1998 to 2017. In our study, they were identified and stratified depending on treatment methods. Overall survival was defined as the time from the date of brain metastases to the death or last follow-up (2019 June 1st). Survival curves were estimated using the Kaplan–Meier method that was employed to calculate the hazard ratio. Results. Six (12%) of 50 patients are still alive as of the last follow-up. The median overall survival from the onset of brain metastases was 11 months. The longest survival time was observed in patients treated by surgery followed by radiotherapy, surgery followed by radiotherapy and systemic therapy, and also radiotherapy followed by systemic therapy. The shortest survival was observed in the best supportive care group and patients treated by systemic therapy only. Conclusions. Patients with brain metastases achieved better overall survival when treated by combined treatment modalities: surgery followed by radiotherapy (26.6 months overall survival), combining surgery, radiotherapy, and systemic therapy (18.7 months overall survival), and also radiotherapy followed by systemic therapy (13.8 months overall survival).
Extraordinary Delayed-Onset Negative Pressure Pulmonary Hemorrhage Resulting in Cardiac Arrest after General Anesthesia for Vocal Cord Polypectomy

Published: November 2020

Negative pressure pulmonary edema and hemorrhage are uncommon but potentially life-threatening complications associated with general anesthesia. Postoperative negative pressure pulmonary edema usually occurs immediately after surgery, and delayed-onset cases occurring more than 1 hour after surgery have rarely been reported. A 37-year-old woman with bronchial asthma underwent vocal cord polypectomy under general anesthesia in another hospital and experienced cardiac arrest due to a negative pressure pulmonary hemorrhage occurring 3 hours and 30 minutes after surgery. She was successfully treated with venoarterial extracorporeal membrane oxygenation and completely recovered without any complications. Extraordinary delayed-onset negative pressure pulmonary hemorrhage occurring more than three hours after surgery has rarely been reported. This case may indicate the need for more careful observation of patients following surgery.

Published: November 2020

Background. Congestive heart failure (CHF) is a complex clinical syndrome, with high morbidity and mortality. Serum anion gap (SAG) is associated with the severity of various cardiovascular diseases. However, the role of SAG indicators in CHF is unclear. Methods and Results. A retrospective analysis of data from Multiparameter Intelligent Monitoring in Intensive Care III version 1.4 was conducted in critically ill patients with CHF. The clinical information of each patient, including demographic data, comorbidities, vital signs, scores, and laboratory indicators, were successfully obtained. Cox proportional hazards models were used to determine the relationship between SAG and mortality in patients with CHF, the consistency of which was further verified by subgroup analysis. Results. A total of 7426 subjects met the inclusion criteria. Multivariate analysis showed that after adjusting for age, gender, ethnicity, and other potential confounders, increased SAG was significantly related to an increase in 30- and 90-day all-cause mortalities of critically ill patients with CHF compared with decreased SAG (tertile 3 versus tertile 1: adjusted hazard ratio, 95% confidence interval: 1.74, 1.46–2.08; 1.53, 1.32–1.77). Subgroup analysis indicated that the association between SAG and all-cause mortality presented similarities in most strata. Conclusion. SAG at admission could be a promising predictor of all-cause mortality in critically ill patients with CHF.
Impacts of PU Foam Stand-Off Layer on the Vibration Damping Performance of Stand-Off Free Layer Damping Cantilever Beams
Authors: Liang Longqiang , Huang Weibo , Lyu Ping , Ma Mingliang , Meng Fandi , Sang Yingjie
Published: November 2020

Stand-off free layer damping is a vibration reduction method based on the traditional free layer damping. In this paper, a stand-off free layer damping cantilever beam is prepared with the steel plate as the base layer, rigid polyurethane (PU) foam as the stand-off layer, and rubber as the damping layer, and the motion equation of the cantilever beam is derived. The dynamic mechanical properties of damping rubber and PU foam are tested and analyzed. Through hammering tests, we have studied the effect of the density and thickness of the PU foam layer on the amplitude-frequency curves, modal frequencies, and loss factors of the cantilever beams. The results show that the rubber damping material is a major font of energy dissipation of the cantilever beam, and PU foam acts mainly to expand the deformation of the damping layer and plays a role in energy consumption. By increasing the density and thickness of PU foam within a certain range, the vibration peaks of the first five modes of the cantilever beam decreases gradually, the loss factors rise, and the damping performance is improved. Meanwhile, increased density and thickness enhances the overall stiffness of the beam, making the modal frequencies get higher.

Trajetória do pensamento preservacionista em Belém a partir dos tombamentos individuais e em conjunto
Authors: Forte Márcia Teixeira Filgueira , Sanjad Thais Alessandra Bastos Caminha
Published: November 2020

O século XX representa o período de surgimento e consolidação da temática preservacionista no Brasil. Dentro desse quadro, a cidade de Belém passa por inúmeras transformações, resultantes das mudanças no modo encarar o seu patrimônio construído. O objetivo principal deste artigo é entender o processo de preservação e transformação do Centro Histórico de Belém, partindo da análise da trajetória do pensamento preservacionista no país e consequentemente na capital. O tema foi subdividido em três momentos: O primeiro momento, compreendido entre as décadas de 1930 e 1960, época dos primeiros tombamentos individuais em Belém; o segundo momento, que abrange as décadas de 1960 a 1980, e caracteriza-se pelos tombamentos dos conjuntos paisagísticos e inclusão dos entornos à leitura dos monumentos; e o terceiro momento, que tem início na década de 1990, com o tombamento do Centro Histórico de Belém, ampliando a abrangência de proteção a conjuntos urbanos. O avanço proveniente do processo de transformação do pensamento preservacionista permitiu a observação do patrimônio de forma mais abrangente, garantindo a preservação da ambiência de conjuntos urbanos da cidade.
cidade neo-capitalista de Lefebvre: mudam as formas, porém a essência permanece
Authors: Rodrigues Luis Carlos Freitas
Published: November 2020

Este artigo faz uma breve a reflexão de como o capitalismo, através do urbanismo contemporâneo, constrói sua lógica de dominação na cidade neocapitalista a partir das reflexões de Lefebvre, principalmente aquelas apresentadas em sua obra O direito à cidade; que expõe o contínuo processo de eliminação das funções cívicas originais da cidade pré-capitalista, moldando o urbano contemporâneo através de uma visão de formação de cidades “lucrativas”, que competem em um teatro global de especulação, marginalização e desigualdade urbana. Em primeiro, será apresentado uma pequena parte da construção sobre a inovação do pensamento marxista, através do Capital de Karl Marx, e da obra Questão de Método de Jean-Paul Sartre. Após isso será realizado uma análise do pensamento lefebvriano, sobre a forma de dominação capitalista que é implementada pelos processos de urbanização.

Expanding Norm and Lingering Fear: Right to Self-determination Debates in Nepal
Authors: Jnawali Hari Har
Published: November 2020

Taking Nepal as a case, this article argues that the meaning of the right to self-determination, in international norms in particular, has expanded from a right to secession to a right to inclusion, but this expansion has not abated the fear of secession on the ground. Nepal understands the ‘right to self-determination’ only as a right to form a new state, and refrains from including this right as a provision in the new Constitution. The three variables – socialisation of the right to self-determination as a norm permitting secession, contrast between formal and informal positions of indigenous leaders, and mainstream bias against the indigenous nationalities – are contributing to state’s reluctance to accommodate this right.
un Post-Conflict Peacebuilding Activities – An Economic Reconstruction Perspective
Authors: De Brabandere Eric
Published: November 2020

The peace versus justice dilemma often presented as paramount in post-conflict situations is more complex and ignores the factual and legal importance of economic reconstruction. The economic aspect of un post-conflict peacebuilding missions, has however not received much attention over the past years. Yet, the mandates granted to international actors after conflicts have undoubtedly evolved throughout the years. From the imposition of a neutral force between the parties to a conflict, to maintaining peace and stability, the un and other international organizations have taken up various responsibilities in the administration of States and territories.

The focus on economic reconstruction needs to be viewed in the context of a changed strategy towards conflicts, in which the focus is laid on ensuring that the causes of the conflict are eliminated. The 1990s, thus, signaled an important and comprehensive shift in the un’s engagement in post-conflict States, which resulted in the establishment of unprecedented missions which included important economic reconstruction activities, such as the international administration missions in Kosovo and East Timor. In recent years however, there have been no comprehensive peacebuilding missions which included major economic reforms in their mandate. There may be multiple reasons for this, but, as is argued, in essence it is the result of two factors. First, international administrative missions, by their very nature, are more adequate tools to engage in comprehensive post-conflict reconstruction efforts including far-reaching economic reforms. Secondly, international financial institution have gradually been moving away from a strict application of their free market policy, towards paying more attention to pluralist rule of law reforms which in turn will trigger economic development.
Judicial Control of Targeted Sanctions by the European Court of Justice
Authors: Fink Sophie
Published: November 2020

In the global fight against international terrorism, the Security Council of the United Nations uses targeted sanctions for the prevention of terrorist attacks and the protection of the population. Starting with Resolution 1267 in 1999, an encompassing listing system was established by the Security Council. The listing system bears various problems regarding the human rights of the listed persons, especially since there is no mechanism of judicial review attached to the listing system.

Following the implementation of these consolidated lists in the European Union, they were challenged before the European Courts. This article describes the development of targeted sanctions, focusing on the different sanctions regimes in the fight against international terrorism and their specific problems. It analyses the judicial review of the sanctions regimes by the European Courts, particularly the Kadi-Judgment of 2008. The article then describes the implications of this judgment not only for the relationship between the law of the un and the eu and for the sanctions regime on the international and European level, but also for the overarching question whether liberty and security can be brought into balance with regard to targeted sanctions.
LL.M. THESIS: The Role of Constitutional Courts in International Investment Law and Investment Treaty Arbitration: A Latin American Perspective
Authors: Fandiño-Bravo Juan Camilo
Published: November 2020

Protection and promotion of foreign investment, one essential element of international economic relations and a cornerstone of the macroeconomic policy of developing States, like Latin-American States, is deemed to be undergoing a ‘legitimacy crisis’ that manifests itself in a generalized discontent by the system’s major stakeholders and some sectors of public society. One of the sources of such crisis can be found in the lack of a proper understanding of the nature of the system itself. After identifying the reasons why the problematiques of International Investment Law and Investment Treaty Arbitration are better understood as matters of public law, this work adopts a comparative public law approach to study the different ways in which Latin-American constitutional courts intervene in International Investment Law and Investment Treaty Arbitration, and outlines the major features of a proposed dialectic relation between constitutional courts and arbitral tribunals, in which constitutional courts can benefit from the study of the findings of arbitral tribunals regarding the nature and scope of substantive standards of protection, among others, in the process of reviewing the constitutionality of International Investment Agreements, and arbitral tribunals can use national constitutional doctrine as one among other public law sources in which to inform their task. The adoption of such an approach will assist in the reduction of the legitimacy gap of International Investment Law and Investment Treaty Arbitration, thus helping to overcome the crisis of the system.
Retour sur un projet de réforme. À propos de „Was war Bielefeld?“
Authors: Hoock Jochen
Published: November 2020

Partant d’un ouvrage collectif qui pose un regard critique sur les projets qui ont mené à la fondation de l’Université de Bielefeld à la fin des années soixante, l’article revient sur les conditions d’émergence de la première Reformuniversität dans l’Allemagne fédérale. Conçue comme un ensemble transdisciplinaire d’enseignement et de recherche selon le modèle esquissé par Wilhelm von Humboldt, l’université de Bielefeld va devoir très vite s’adapter au pragmatisme dominant dans les années 1970, se soumettre à une modernisation adaptative et de ce fait subir un échec par rapport à la conception initiale. Un secteur cependant échappe à ce que l’on a appelé le ‘Bielefelder Syndrom’ : celui des Sciences sociales et historiques et son centre interdisciplinaire de recherches (ZiF) constituant l’ ‘Ecole de Bielefeld’ autour de figures marquantes, diverses mais complémentaires, comme les historiens Reinhart Koselleck, Hans-Ulrich Wehler, Jürgen Kocka et des sociologues comme Niklas Luhmann.

A new species of Pseudovaigamus Amado, Ho & Rocha, 1984 (Cyclopoida: Ergasilidae) from the teleost Pimelodus maculatus Lacepède, 1803
Authors: NARCISO RODRIGO B. , PERBICHE-NEVES GILMAR , SILVA REINALDO JOSÉ DA
Published: November 2020

A new species of the copepod genus Pseudovaigamus Amado, Ho & Rocha, 1984 is described herein based on parasitic adult females found attached to the gills of the freshwater teleost Pimelodus maculatus Lacepède, 1803, sampled in two tributaries (Veados and Paranapananema Rivers) of the Jurumirim Reservoir, Upper Paranapanema River, São Paulo State, Brazil. The new copepod was identified as an undescribed species of Pseudovaigamus because it shares with the type-species, Pseudovaigamus spinicephalus (Thatcher & Robertson, 1984), the combination of first leg with 2-segmented endopod, fourth leg with 3-segmented endopod and 2-segmented exopod, and cephalothorax armed with dorsolateral stylets (or retrostylets). However, the new copepod differs from its congener in having a trifid rostral spine, retrostylets with long spatulate process, 5-segmented antennule, and caudal rami simple or lacking any distal lobe. We erected a new species, Pseudovaigamus tridentatus n. sp.. It is the first report of a Pseudovaigamus found on a freshwater fish in Brazil.

MicroRNA-disease association prediction by matrix tri-factorization
Authors: Li Huiran , Guo Yin , Cai Menglan , Li Limin
Published: November 2020

Background

Biological evidence has shown that microRNAs(miRNAs) are greatly implicated in various biological progresses involved in human diseases. The identification of miRNA-disease associations(MDAs) is beneficial to disease diagnosis as well as treatment. Due to the high costs of biological experiments, it attracts more and more attention to predict MDAs by computational approaches.

Results

In this work, we propose a novel model MTFMDA for miRNA-disease association prediction by matrix tri-factorization, based on the known miRNA-disease associations, two types of miRNA similarities, and two types of disease similarities. The main idea of MTFMDA is to factorize the miRNA-disease association matrix to three matrices, a feature matrix for miRNAs, a feature matrix for diseases, and a low-rank relationship matrix. Our model incorporates the Laplacian regularizers which force the feature matrices to preserve the similarities of miRNAs or diseases. A novel algorithm is proposed to solve the optimization problem.

Conclusions

We evaluate our model by 5-fold cross validation by using known MDAs from HMDD V2.0 and show that our model could obtain the significantly highest AUCs among all the state-of-art methods. We further validate our method by applying it on colon and breast neoplasms in two different types of experiment settings. The new identified associated miRNAs for the two diseases could be verified by two other databases including dbDEMC and HMDD V3.0, which further shows the power of our proposed method.
The health effects of gendered and devalued work: health outcomes of incarcerated women engaging in sex work and care/service work
Authors: Kim Sage J. , Peterson Caryn
Published: November 2020

Background

Women with a history of incarceration are often engaged in highly gendered work, either sex work or low-wage care/service work jobs. While employment is an important element of reentry plans, low-wage jobs may not necessarily help women leave illicit activities, including commercial sex work. Incarcerated women often move between care/service work and sex work to supplement income, putting them at greater risk for negative health outcomes.

Results

Using survey data from 400 women detained in a large urban jail, we examined how incarcerated women’s experience with sex work and low-wage care/service work affects four health-related outcomes: overall health concerns, clinical depression, regular drug use, and self-esteem. Of the survey participants, 24% engaged exclusively in sex work and 34% in care/service work. However, 41% of women held both sex work and care/service work jobs, prior to incarceration. Compared to women engaged in care/service work, a greater proportion of women engaged in sex work reported overall health concerns, clinical depression, and regular drug use. On the other hand, women in care/service work jobs exclusively reported lower levels of self-esteem than women engaging in sex work.

Conclusions

Many reentry programs emphasize the importance of employment for former inmates, and yet, job options for women detained in jail are often limited to low-wage care/service jobs, which do not necessarily provide adequate security to lift women’s economic burdens. Consequently, many women with a history of incarceration may supplement their income with sex work to meet their basic economic needs. However, both of these highly gendered and devalued jobs may negatively affect health and wellbeing of women.
The influence of urban park characteristics on bird diversity in Nanjing, China
Authors: Yang Xueru , Tan Xinwei , Chen Chuanwu , Wang Yanping
Published: November 2020

Background

Habitat loss, fragmentation and decrease of habitat quality caused by urbanization have led to a dramatic decline in biodiversity worldwide. For highly urbanized areas, parks have become “islands” or habitat fragments for wildlife. As an important indicator group of urban ecosystem health, the response of birds to urbanization has attracted the global attention of ecologists. Understanding the key factors affecting bird diversity in urbanized environment is crucial to the protection of biodiversity in urban ecosystems.

Methods

We used the line-transect method to survey birds in 37 urban parks in Nanjing, China. We also measured a number of park characteristics (area, isolation, shape index, environmental noise, distance to city center, and habitat diversity) that are commonly assumed to influence bird diversity. We then used the information-theoretic multi-model inference approach to determine which park characteristics had significant impacts on bird species richness.

Results

We found that park area, habitat diversity and the distance to city center were the best positive predictors of bird species richness in Nanjing urban parks. By contrast, park isolation, park shape and environmental noise had little or no influence on bird diversity.

Conclusions

Our study highlights the importance of park area, habitat diversity and the distance to city center in determining bird diversity in Nanjing city parks. Therefore, from a conservation viewpoint, we recommend that large parks with complex and diverse habitats far away from the city center should be retained or constructed to increase bird diversity in urban design and planning.
Europäische Diskursgemeinschaft.

Published: November 2020

Europe is a unique framework of communication with similar issues discussed in different linguistic and cultural areas. This paper gives a detailed overview of a discourse linguistic project that analyses this multilingual discourse space. We focus on the issue of vaccination since this is a controversial issue in the media of all countries that are of interest for this study (Germany, Italy, France, UK). Methods from discourse, corpus and computer linguistics are used to identify the most relevant linguistic, argumentative, and emotional patterns in discourse. The paper discusses these methods in detail. We then show how these patterns are annotated in our corpora and how the different kinds of annotations can be analysed in correlation.
Searching for the bilingual advantage in executive functions in speakers of Hunsrückisch and other minority languages: a literature review
Authors: Abreu Elisabeth , Limberger Bernardo
Published: November 2020

The issue of a bilingual advantage on executive functions has been a hotbed for research and debate. Brazilian studies with the minority language Hunsrückisch have failed to replicate the finding of a bilingual advantage found in international studies with majority languages. This raises the question of whether the reasons behind the discrepant results are related to the language’s minority status. The goal of this paper was to investigate the bilingual advantage on executive functions in studies with minority languages. This is a literature review focusing on state of the art literature on bilingualism and executive functions; as well as a qualitative analysis of the selected corpus in order to tackle the following questions: (1) is there evidence of a bilingual advantage in empirical studies involving minority languages? (2) are there common underlying causes for the presence or absence of the bilingual advantage? (3) can factors pertaining to the language’s minority status be linked to the presence or absence of a bilingual advantage? The analysis revealed that studies form a highly variable group, with mixed results regarding the bilingual advantage, as well as inconsistent controlling of social, cognitive and linguistic factors, as well as different sample sizes. As such, it was not possible to isolate which factors are responsible for the inconsistent results across studies. It is hoped this study will provide an overview that can serve as common ground for future studies involving the issue of a bilingual advantage with speakers of minority languages.
Die Interjektion boah in Alltagserzählungen:
Authors: Meiler Matthias , Huynh Ilham
Published: November 2020

This paper examines conversational data of German everyday narratives in audiovisual footage of face-to-face encounters and in log files of Facebook’s instant messenger. The qualitative analysis is focused on the interjection boah as a means of narrative activity, paying special attention to its multimodal form and its media dependent functionality. The preliminary findings show that boah is used to signal to the communication partner the utterer’s noticing of something unexpected: be it an observed object or event, a communicative action, or a recalled memory. On a phonetical level, it is possible to distinguish two forms of boah: a marked form and an unmarked form. Which of these two forms is instantiated in interaction depends on the intensity of unexpectedness (or the enactment of unexpectedness). In everyday narratives, the marked form is often found to be expressed by the recipient. In contrast to the face-to-face data, our instant messenger data shows that, here, almost without exception boah is only used by the storyteller. This conspicuous finding can be explained by the specific temporality of instant messaging which results from the structural media conditions that instant messengers or e. g. internet relay chats similarly impose on the use of communicative means like interjections. We finally discuss how this dialectic relation between communicative function and mediality prompts further analyses of other communicative means, for example, the pattern of everyday narratives itself.

Authors: Weinberger Robert , Prinz Robin
Published: November 2020

In der heutigen Zeit werden alle Branchen auf Nachhaltigkeit eingestellt, so auch die Informatik. Hier werden drei Ziele verfolgt, welche zukünftig mithilfe der IT erreicht werden sollen. Diese sind der schonende Umgang mit begrenzten und wertvollen Ressourcen, das systematische Recycling von Altgeräten und eine sparsame Energiepolitik. Für diese wiederum gibt es verschiedene Ansätze. Ein Ansatz ist die Wiederaufbereitung von bereits gebrauchter Hardware mit dem Ziel die Nutzungsdauer von Geräten zu verlängern, um so die benötigten Rohstoffe länger im Nutzungskreislauf zu behalten. Am Beispiel von Laptops wird gezeigt, welche Faktoren die Kaufentscheidung von Käufern beeinflussen und wie sich die allgemeine Verteilung von Laptops in den Haushalten darstellt. Die Umfrage umfasst 870 Probanden, welche zu Ihrer Einstellung zum Thema Wiederaufbereitung und Nachhaltigkeit von Laptops befragt werden. Anhand der Ergebnisse soll aufgezeigt werden, welche Unterschiede zwischen verschiedenen Personengruppen im Hinblick auf die Akzeptanz von wiederaufbereiteten Laptops bestehen und wie stark der Einfluss des Nachhaltigkeitsaspektes bei der Entscheidung für wiederaufbereitete Geräte ist. Abschließend werden Handlungsempfehlungen für Maßnahmen zur Stärkung der Marktposition von wiederaufbereiteter Hardware vorgestellt.
BioAFMviewer: An interactive interface for simulated AFM scanning of biomolecular structures and dynamics
Authors: Amyot Romain , Flechsig Holger
Published: November 2020

We provide a stand-alone software, the BioAFMviewer, which transforms biomolecular structures into the graphical representation corresponding to the outcome of atomic force microscopy (AFM) experiments. The AFM graphics is obtained by performing simulated scanning over the molecular structure encoded in the corresponding PDB file. A versatile molecular viewer integrates the visualization of PDB structures and control over their orientation, while synchronized simulated scanning with variable spatial resolution and tip-shape geometry produces the corresponding AFM graphics. We demonstrate the applicability of the BioAFMviewer by comparing simulated AFM graphics to high-speed AFM observations of proteins. The software can furthermore process molecular movies of conformational motions, e.g. those obtained from servers which model functional transitions within a protein, and produce the corresponding simulated AFM movie. The BioAFMviewer software provides the platform to employ the plethora of structural and dynamical data of proteins in order to help in the interpretation of biomolecular AFM experiments.

Published: November 2020

The present paper aims to estimate the impact of the reductionof the generation interval, based on the model of fetal ovarian tissuexenotransplantation associated with in vitro embryo production toestimate the annual genetic gain of weight traits in a bovine herd. Weighdata and genealogy of Brahman animals were used to estimate the annualdirect genetic gain for weight at birth, weight at 120 days, at 210 days,and at 550 days of age. The genetic parameters were obtained by animalmodel, via Bayesian inference, by Markov Chain Monte Carlo (MCMC)methods. For the estimates, different generation intervals were defined asthe average value between the supposed maternal generation intervalsand the average sire generation interval based on the analyzed data (9.6years). The shortest generation interval considered was 5.1 years, outlinedfrom the average of 0.66 year (corresponds to 8 fetal months, anassumption defined based on the use of fetal ovarian tissuexenotransplantation associated with in vitro embryo production) and 9.6years (sire generation interval). The remaining intervals considered were6.7, 8.7 and 10.2 years. The estimate of annual direct genetic gain for allthe evaluated traits was higher when considering the generation intervaloutlined based on the model of fetal ovarian tissue xenotransplantationassociated with in vitro embryo production. The estimates were lower asthe generation interval increased. The use of fetal ovarian tissuexenotransplantation associated with in vitro embryo production, may favorthe reduction of the generation interval and successively generate apositive impact on the annual direct genetic gain estimates.
Recognising Devanagari Script by Deep Structure Learning of Image Quadrants
Authors: Susan Seba , Malhotra Jatin
Published: November 2020

Ancient Indic languages were written in the Devanagari script from which most of the modern-day Indic writing systems have evolved. The digitisation of ancient Devanagari manuscripts, now archived in national museums, is a part of the language documentation and digital archiving initiative of the Government of India. The challenge in digitizing these handwritten scripts is the lack of adequate datasets for training machine learning models. In our work, we focus on the Devanagari script that has 46 categories of characters that makes training a difficult task, especially when the number of samples are few. We propose deep structure learning of image quadrants, based on learning the hidden state activations derived from convolutional neural networks that are trained separately on five image quadrants. The second phase of our learning module comprises of a deep neural network that learns the hidden state activations of the five convolutional neural networks, fused by concatenation. The experiments prove that the proposed deep structure learning outperforms the state of the art.

Breast cancer (BC) and cervical cancer (CC) have a high prevalence and mortality rate worldwide. Despite the availability of advanced treatment, resistance to conventional chemotherapies has emerged. Myrmecodia pendens, one of the species of Sarang Semut (local name), possess a potential of antitumor effects by inducing cell death different cancer cell entities. This study aimed to assess anti-tumor activities of n-hexane fraction of M. pendens in inhibiting cell survival and cell migration in BC and CC cells. M. pendens was extracted in methanol then fractionated using n-hexane or ethyl acetate. BC cells including MCF-7 (luminal A), HCC-1954 (HER2+) cells and CC Hela cells were treated with M. pendens extracts to evaluate cytotoxic activity using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay as well as anti-cell migration using scratch assay. We also analyzed inhibitory concentration 50 (IC50) of n-hexane fraction in BC and CC cells. We started with comparing cytotoxicity activities of methanol extract, ethyl acetate and n-hexane fractions of M. pendens. Data showed that the n-hexane fraction was the most potent inducing BC cell death. Therefore, we used the n-hexane fraction for further experiments. Interestingly, IC50 of this fraction in HCC-1954 and Hela cells were lower than in MCF-7 cells, 16; 13 and 60 ppm, respectively. Moreover, the low concentrations of n-hexane fraction inhibited HeLa cells migration, compared to control group (p<0.05). The n-hexane fraction of M. pendens shows promising anti-cancer agent, by inhibiting BC and CC cell survival as well as inhibiting CC cells migration.Keywords: breast cancer, cervical cancer, MTT assay, Sarang Semut, scratch assay
The Sharing Perspectives Foundation: a case study in blended mobility
Authors: Millner Sophie C.
Published: November 2020

This case study explores the Sharing Perspectives Foundation’s (SPF) blended mobility course: Europe on the Edge, which included a 10-week Virtual Exchange (VE) followed by a 1-week physical mobility held in Brussels. Engaging 131 students from 30 different nationalities and partnering with 10 European universities, this 2015 intercultural exchange aimed to give students from diverse backgrounds the space to completely rethink what it meant to be a citizen in contemporary Europe. The 1-week event in Brussels at the end of the course for a selected group of 15 students created an opportunity for physical mobility and makes this an interesting case study for analysing the value of blended mobility.
Implementing E+VE at the University of Bordeaux within English for specific purposes courses
Authors: Hoskins Laüra , Reynolds Alexandra
Published: November 2020

This case study reports on an Erasmus+ Virtual Exchange (E+VE) course at the University of Bordeaux. VE enables students to develop communication skills in an English as a Lingua Franca (ELF) environment (Helm, 2016; Kohn & Hoffstaedter, 2017). The present study reports on student language and content learning experiences through E+VE, where L2 users of English interacted with a more culturally diverse group of peers than they would likely meet in their local area. Our students’ perspectives echo the E+VE impact report (Helm & Van Der Velden, 2019) and place a particular emphasis on English language learning outcomes.
The Contribution of Gifted Individuals and Nonconformist Behaviours to Virtues in the Public Sphere
Authors: Gierczyk Marcin
Published: November 2020

Giftedness and nonconformist behaviour have become a source of great interest in both the public sphere and in educational research. This is related to the fact that nonconformity (as a personality and character trait) has been, and still is, an indispensable element of the creative transformation of societies in the public sphere.1 The paper presents results of research conducted in the years 2014-2016 on the level of nonconformity of gifted students in Poland and England. The research, conducted with the Creative Behaviour Questionnaire III (CBQ III), was undertaken among 30 purposefully selected students from the University of Silesia (Poland) as well as Oxford University (England). By considering both the influence of nonconformists on the transformations taking place in the public sphere, and also the results of my research, I will examine whether nonconformity is a potential source of strength or weakness to the public sphere. In this context nonconformist is a person who does not conform to a generally accepted pattern of thought or action.
Ponadczasowa doniosłość pedagogiki porównawczej Bogdana Nawroczyńskiego

Published: November 2020

The subject of the analysis are the excellent scientific achievements in the field of comparative pedagogy presented by Professor Bogdan Nawroczyński (1882-1974). His contacts with the world’s leading scholars in the field of pedagogy of the New Education resulted in a radical change in comparative studies in Polish pedagogy. I pay attention to the universality of Nawroczyński’s thought and its integrity with the theory of personality and education of young people. I am introducing his contribution to the internationalization of pedagogy, its systematisation and typology of pedagogical thought.
Analysis of heart rate variability during a mental image session of a walk
Authors: Martinez Jonathan , Mourot Laurent
Published: November 2020

The study of the autonomic nervous system (ans) has become relevant due to its response during sports training. Exercise itself improves ans status, but overtraining induces a state of chronic fatigue, unbalancing ans activity. Therefore, it is necessary to find other methods to improve the sporting performance. The mental image (mi) has been shown as an effective method to improve the performance of certain motor conditions in athletes, exhibiting the activation of the ans. mi sessions could be used as a training method; thus, the objective of this research was to identify if there is a significative activation of the ans during and after mi sessions. The heart rate of 15 subjects was monitored during a physical session and during an mi session of a walk in two different speeds. Data was analyzed through anova and it did not show significative changes in the heart rate variability during or after the mi. It’s possible that the result of this research was influenced by the mental effort, the lack of training in mi, and the time used to obtain the data to analyze the heart rate variability.

OIL TRANSPORT AND PROTECTING CLEAN WATER: THE CASE OF THE DAKOTA ACCESS PIPELINE (DAPL)
Authors: White George W. , Millett Bruce V.
Published: November 2020

Oil frequently plays a crucial role in modern industrial economies. It is a very costly natural resource for those countries that do not have it, but very profitable for those that do. Yet, developing oil resources and transporting them to market has its own costs, not only in terms of production but also in terms of impacts on other valuable natural resources such as clean water. Not surprisingly, governments can have strict environmental regulations concerning oil transport. However, such regulations can be complicated, especially in countries like the United States where many different government agencies claim jurisdiction, especially at differing spatial scales. Consequently, conflict can result from competing interests, pitting those developing oil resources against those already using resources such as clean water. This paper explores the complicated geographies of environmental regulations and how competing entities pursue and protect their interests through environmental ligation. In doing so, this study uses the example of the Dakota Access Pipeline (the DAPL) because the conflict surrounding it garnered considerable national and international attention.

Published: November 2020

The article is dedicated to assessment of the state and use of lakes and reservoirs situated in the Central Region of the Republic of Moldova. The results showed that 1155 reservoirs and ponds with a total area of 11.4 ths. ha are situated in the limits of 14 districts. Over half of them are constructed on the streams. At the district level, the biggest number of lakes is located in Călărași (204), Orhei (139) and Ungheni (136), but the largest surface is attested in Ialoveni (1844 ha), Ungheni (1584 ha), Teleneşti (1358 ha). The reservoir basin status is satisfactory only in case of 1/3 (381) of reservoirs, 40% being silted. Hydro-technical infrastructure is satisfactory at ≈2/3 of reservoirs. The reservoirs are used for fishery (34%), general use (31%), irrigation (13%), mixed use (7%). Only 47 lakes or 12% are used mainly for recreational purposes.
