Jaunu burtu veidošana ar diakritiskajām zīmēm latviešu valodas kā svešvalodas apguvēju tekstos
Authors: Kaija Inga
Published: May 2020

A Latvian learner corpus “LaVA” is being built in the Institute of Mathematics and Computer Science, University of Latvia. The corpus includes texts written by beginner learners in the first two semesters of learning Latvian as a foreign language. The texts are written by hand and digitized afterwards in order to reduce the issues that could be caused by the necessity to learn not only writing itself but also using a foreign keyboard.
One of the features that cannot be digitized is the new letters created by adding diacritical marks which are not used that way in the standard Latvian alphabet. Since one of the essential steps in learning to write in a language is learning the letters and diacritical marks of that language, this study aims to find instances of such newly made letters and to discuss the basic quantitative measures in order to define hypotheses and areas of interest for further research of such usage.
Altogether 322 texts were searched, and 175 examples were found. The amount of examples found in 2nd semester texts was less than half the amount of examples found in the 1st semester texts, but the percentage of texts containing examples was higher than expected – more than 33 % in the 1st semester and almost 20 % in the 2nd semester. It leads to a conclusion that this is quite a common occurrence but also prone to reduction in the second semester. The corpus does not provide any data on later semesters so it cannot be predicted when such instances should become a rare, individual feature rather than a common one.
The average amount of examples in a text is not high, though. Counting only the texts where at least one example was found, the average amount of examples per text is 2.136 in the 1st semester and 1.690 in the 2nd semester. Considering that the absolute lowest possible value here is 1, it should not be considered as a high value. Therefore, using diacritical marks to make new letters, while a common feature of the Latvian interlanguage, could be characterized as casual rather than systemic.
However, that does not exclude the possibility of certain patterns in usage. The currently collected data already shows that there are some words – such as garšo, viņš, ļoti, četri – where examples were found in more than one author’s text. Examples of using unsuitable diacritical marks are also sometimes found next to letters for which said diacritical marks would be suitable. This should be explored more thoroughly using qualitative methods.
The size of the corpus keeps growing; the expected size upon completion is 1000 texts. When it is reached, it would be useful to repeat the study and check whether the larger amount of data still confirms the same assumptions. The larger sample size would also allow for more detailed quantitative analysis discussing each letter, diacritical mark, placement of the diacritical mark, and metadata collected for the corpus, such as gender, native language and other spoken languages by the authors of the texts.

Concurrent guidance of attention by multiple working memory items: Behavioral and computational evidence
Authors: Zhou Cherie , Lorist Monicque M. , Mathôt Sebastiaan
Published: May 2020

During visual search, task-relevant representations in visual working memory (VWM), known as attentional templates, are assumed to guide attention. A current debate concerns whether only one (Single-Item-Template hypothesis; SIT) or multiple (Multiple-Item-Template hypothesis; MIT) items can serve as attentional templates simultaneously. The current study was designed to test these two hypotheses. Participants memorized two colors, prior to a visual-search task in which the target and the distractor could match or not match the colors held in VWM. Robust attentional guidance was observed when one of the memory colors was presented as the target (reduced response times (RTs) on target-match trials) or the distractor (increased RTs on distractor-match trials). We constructed two drift-diffusion models that implemented the MIT and SIT hypotheses, which are similar in their predictions about overall RTs, but differ in their predictions about RTs on individual trials. Critically, simulated RT distributions and error rates revealed a better match of the MIT hypothesis to the observed data than the SIT hypothesis. Taken together, our findings provide behavioral and computational evidence for the concurrent guidance of attention by multiple items in VWM.

Les corps dans les révolutions arabes
Authors: Salime Zakia
Published: May 2020

La question de la corporalité et de la sexualité a envahi l’espace médiatique des révolutions arabes. Durant ces révolutions, le corps des femmes est devenu un champ de bataille autour duquel se sont joués plusieurs agendas, islamiste, civil, laïque, féministe, sécuritaire et géopolitique. A la pluralité de ces références correspond une pluralité de corps de femmes, « libérés », résistants, défiants ou conformistes. Dans plusieurs récits sur la révolution les femmes ont été célébrées et reconnues comme agents politiques et de parole. L’article pose la question de savoir si la célébration de ces corps libres, nus, et exposés au toucher et à la violence orchestrée par l’État, lors de ces révolutions, ne marginaliserait pas d’autres femmes qui n’ont pu avoir accès à la parole qu’à travers l’élimination de leurs corps ? Comment un corps réduit au silence peut-il nous parler durant ces soulèvements ? Deux notions répondent à ces questions, la notion de micro-rébellion et celle de légitimité donnée à certaines causes et donc aux corps qui les soutiennent.
Femmes en mouvement, femmes en politique

Published: May 2020

L’article montre le décalage entre la forte participation des femmes aux différentes étapes de la révolution tunisienne, d’une part, et leur éviction d’un certain nombre de débats publics, d’autre part. Il propose de nouveaux modèles pour comprendre les diverses formes de mobilisation et développe une nouvelle approche des mouvements sociaux dans les politiques du conflit. Partant de la critique du modèle habermassien de l’espace public par Nancy Frazer, l’article décrit quelques mouvements militants de femmes en Tunisie, « arènes subalternes », en s’appuyant sur des enquêtes menées en 2013-2014 et en montrant leurs particularités par rapport à d’autres formes d’engagement.
Politique de réinsertion professionnelle et surmoi collectif
Authors: Monneret Claude
Published: May 2020

Nous assistons à l’influence croissante, défavorable de l’idéologie de l’économie de marché et de « sa valeur travail » sur la subjectivité des individus, qui est modifiée dans ses trois dimensions : topique, économique et dynamique. Cette économie impose en effet aux individus son surmoi collectif dans les secteurs de l’entreprise et de la politique, mais aussi dans le champ de la santé mentale où ses concepts s’appliquent. Les valeurs de l’économie de marché infiltrent le discours et les pratiques des soignants et l’on voit se développer des pratiques thérapeutiques de réhabilitation professionnelle, rééducatives et adaptatives, cognitivo-comportementales. Si la valeur du travail dans la vie du sujet n’est plus à démontrer, la demande faite aux soignants de réadapter au milieu professionnel les patients présentant des troubles psychiques est à questionner. De même, on peut déplorer la conception réductrice de la psyché et la théorie réifiante du sujet, qui sous-tendent des pratiques qui méconnaissent la dimension inconsciente des symptômes. Le discours circonscrit au conscient, au réel, subvertit le sujet de l’énonciation et l’intersubjectivité. Le sujet du moi et du conscient risque de remplacer le sujet freudien, sujet du désir, dans le champ de la santé mentale.
SUMOylation of DDX39A Alters Binding and Export of Antiviral Transcripts to Control Innate Immunity
Authors: Shi Peidian , Guo Yanyu , Su Yanxin , Zhu Min , Fu Yali , Chi Heng , Wu Jiaqi , Huang Jinhai
Published: May 2020

The RNA helicase DDX39A plays an important role in the RNA splicing/export process. In our study, human DDX39A facilitated RNA virus escape from innate immunity to promote virus proliferation by trapping TRAF3, TRAF6, and MAVS mRNAs in the HEK293T cell nucleus. DDX39A was a target for SUMOylation. SUMO1, 2, and 3 modifications were found on immunoprecipitated DDX39A. However, only the SUMO1 modification decreased in vesicular stomatitis virus–infected HEK293T cells. Further studies have found that viral infection reduced SUMO1 modification of DDX39A and enhanced its ability to bind innate immunity–associated mRNAs by regulating the abundance of RanBP2 with SUMO1 E3 ligase activity. RanBP2 acted as an E3 SUMO ligase of DDX39A, which enhanced SUMO1 modification of DDX39A and attenuated its ability to bind RNA. This work described that specific mRNAs encoding antiviral signaling components were bound and sequestered in the nucleus by DDX39A to limit their expression, which proposed a new protein SUMOylation model to regulate innate immunity in viral infection.
An SAMT-247 Microbicide Provides Potent Protection against Intravaginal Simian Immunodeficiency Virus Infection of Rhesus Macaques, whereas an Added Vaccine Component Elicits Mixed Outcomes

Because of microbicide noncompliance and lack of a durable, highly effective vaccine, a combined approach might improve HIV prophylaxis. We tested whether a vaccine–microbicide combination would enhance protection against SIV infection in rhesus macaques. Four macaque groups included vaccine only, vaccine–microbicide, microbicide only, and controls. Vaccine groups were primed twice mucosally with replicating adenovirus type 5 host range mutant SIV env/rev, gag, and nef recombinants and boosted twice i.m. with SIV gp120 proteins in alum. Controls and the microbicide-only group received adenovirus type 5 host range mutant empty vector and alum. The microbicide was SAMT-247, a 2-mercaptobenzamide thioester that targets the viral nucleocapsid protein NCp7, causing zinc ejection and preventing RNA encapsidation. Following vaccination, macaques were challenged intravaginally with repeated weekly low doses of SIVmac251 administered 3 h after application of 0.8% SAMT-247 gel (vaccine–microbicide and microbicide groups) or placebo gel (vaccine-only and control groups). The microbicide-only group exhibited potent protection; 10 of 12 macaques remained uninfected following 15 SIV challenges. The vaccine-only group developed strong mucosal and systemic humoral and cellular immunity but did not exhibit delayed acquisition compared with adjuvant controls. However, the vaccine–microbicide group exhibited significant acquisition delay compared with both control and vaccine-only groups, indicating further exploration of the combination strategy is warranted. Impaired protection in the vaccine–microbicide group compared with the microbicide-only group was not attributed to a vaccine-induced increase in SIV target cells. Possible Ab-dependent enhancement will be further investigated. The potent protection provided by SAMT-247 encourages its movement into human clinical trials.
Women Leadership in Public Sector – Evidence from Serbia
Authors: Dragičević Iva , Mihić Marko
Published: May 2020

The role of women in society every day is growing. Women achieve significant business outcomes, along with men, although their efforts are often not evaluated in the same way. Despite their extraordinary commitment to the jobs they perform, women still find themselves in the so-called "glass ceiling" - barriers that prevent them from progressing to better careers and to be equally valued and paid as men. Nowadays, there is a great desire and engagement of all layers of society and the state to change that situation so that women can prove their abilities in the most responsible positions, both in companies and public sectors as well. This paper starts from the fact that there is no favoring of men in relation to women in management positions in the state administration in Serbia, and that the main preconditions for someone to perform these functions are knowledge, education and work experience.

Exogenous liquidity risk measurement is a measurement of liquidity risk that affects all market participants and is not affected by the actions of any other actors. Exogenous liquidity risk measurement is usually called the Cost of Liquidity (COL). The main problem is how the level of liquidity of one currency against other currencies and the effect of liquidity risk on VaR (Value at Risk) on a single asset. This thesis examines the importance of liquidity risk on a single asset. Combining basic VaR and liquidity risk will result in more effective calculations. The model used is to add the basic VaR value with the Cost of Liquidity (COL) or also called Liquidity VaR (L-VaR). The calculation results show the different effects of liquidity for each country's currency. Indonesian Rupiah (IDR) is the currency that has the highest liquidity component compared to the Japanese Yen (JPY) and the Thai Baht (THB). The lower the liquidity component of a currency, the currency is very liquid, and the Japanese Yen (JPY) is the most liquid currency compared to the Indonesian Rupiah (IDR) and the Thai Baht (THB).

A review of MALL: from categories to implementation. The case of Apple’s iPad
Authors: Morgana Valentina
Published: May 2020

The use of mobile devices inside and outside formal settings is often associated to innovative practices in the design of language learning activities. This often implies the reconceptualization of language learning tasks and of the role of the teacher in the mobile classroom. In order to investigate current research and practices in secondary and higher education a review of recent studies in the field of MALL has been undertaken with the main aim of identifying main trends, implementation practices and research gaps.

This paper presents a synthesis of the literature by analysing the four different MALL categories, as presented in Pegrum (2014) and selecting a series of case studies and trends that may be implemented in various educational settings with a specific focus on the use of the iPad in second language settings. The review sought to provide a picture of the various options of MALL task-design and recent implementation practices in secondary and higher education using a specific tablet device. General findings show that many studies are more descriptive than innovative and advocate the implementation of larger and long-term research studies on how mobile devices, and the iPad in particular, are impacting language teaching and learning. Keywords: Mobile-assisted language learning, review, iPAD, task design.
Impact and reactions to a blended MA course on Language Education and Technology
Authors: Ypsilandis George
Published: May 2020

The subject of computers in language learning was not covered at a postgraduate level in Greece independently but as an add-on module in more broad programmes, such as applied linguistics or TEFL. In such programmes, this module was merely scratching the surface of the subject, leaving students with the impression that there was no more to it than learning to run a software programme or an application. The MA programme on Language Education and Technology (LET) was the first in the country that aimed to offer a specialised course with all its modules directly related to the area. Furthermore, the programme attempted to incorporate a number of novelties in the personnel involved (experts from six different countries), methods of teaching (blended, through face-to-face, and synchronous web teleconferencing), transparency (as to the use and allocation of the fees and student selection), systems of examination, modes of collaboration, and modules and seminars offered, all directly linked to its title.

The study described here aimed to shed light and estimate the impact of the course on the professional life of its participants through several open and closed questions included in a questionnaire, constructed to register student status before and after the programme, and their opinions on several other programme features. Students scored very positively a) module development, b) the instructors that were involved, c) the modules offered, and d) the knowledge they gained. Some of the students presented their final papers at international conferences, four were accepted in PhD studies in Spain, the UK and Austria, with scholarships from the host institution, while others increased their salaries, or found a new better paid job.
A Protocol for a Systematic Review to Study the Efficacy and Safety of Ayurveda Intervention in Children and Adolescent with Attention-deficit/Hyperactivity Disorder
Authors: Choudhary Kuldeep , Dave Parth P , Goel Sumeet , Gundeti Manohar S
Published: May 2020

Background:

Various clinical researches have been done in Ayurveda to study the effectiveness of Ayurveda intervention in attention-deficit/hyperactivity disorder (ADHD), one of the most common neurodevelopmental disorders in pediatric population. However, to date, no comprehensive systematic review has been conducted to assess the quality of clinical trials conducted and to determine the strength and safety of Ayurveda interventions in ADHD.

Materials and methods:

Published randomized clinical trials (RCTs), non-RCTs, and unpublished data on Ayurveda intervention in ADHD will be searched by using electronic databases such as the Cochrane Library, Pubmed, CENTRAL, Science Direct, AYUSH research portal, and other Indian databases. It involves the hand-searching of Ayurveda journals, and PG/PhD dissertations, if available, will also be utilized. The selection of study, data extraction, and synthesis will be done independently by reviewers. Standard tools will be adopted to assess the quality of trials. Risk of bias assessment will be performed by using Cochrane tool of risk of bias for RCTs and risk of bias in non-randomized studies of interventions (ROBINS-I) tool for non-RCTs. A narrative synthesis of findings from included studies will be described by providing treatment effect size. If sufficient data are available, the meta-analysis will be performed by using Review Manager.

Outcome:

The proposed protocol will act as a guiding tool for reproducing the same results in a transparent manner and to provide information to healthcare practitioners and policy makers.

Published: May 2020

Background:

Conjunctivitis is a common condition of the eye that occurs worldwide and affects all ages and social strata, affecting more than 2% of the population. Conventional treatment has many options for treating the disease. Despite adequate treatment options, patients continue to suffer troublesome symptoms. Complementary and alternative medicine (CAM) therapies may play a significant role here. Systematic reviews on this topic have been published for herbal medicines. Data are available on plenty of studies individually proving efficacy and safety of various Shodhana, Shamana, and Netra Kriyakalpa in conjunctivitis. However, systematic review of Ayurveda interventions for conjunctivitis is unavailable. This study aims at a thorough review of published clinical data of safety and efficacy of Ayurvedic interventions in the management of conjunctivitis.

Materials and methods:

A systematic review of randomized controlled trials (RCTs), quasi-randomized controlled trials (QRCTs), controlled clinical trials (CCTs), and multiple arms clinical trials on conjunctivitis published till date will be conducted. Studies having patients fulfilling the diagnostic criteria based on the symptomatology of Abhishyanda (HF-1) explained in classic Ayurveda texts and conjunctivitis of all ages and either sex will be included. Studies in which Ayurvedic treatments (Shamana, Shodhana, or/and Netra Kriyakalpa) with any dose, type, schedule, drug, dosage form, and advised Pathayapathya (lifestyle changes) as intervention or control will be selected. The primary outcome will be the response to treatment and onset of serious adverse events.

Ethics and dissemination:

Formal ethical approval will be obtained. The results will be disseminated through a peer-reviewed publication.

Abstract. Data assimilation (DA) provides better initial states of model runs by combining observational information and models. Ensemble-based DA methods that depend on the ensemble run of a model have been widely used. In response to the development of seamless prediction based on coupled models or even earth system models, coupled DA is now in the mainstream of DA development. In this paper, we focus on the technical challenges in developing a coupled ensemble DA system, which have not been satisfactorily addressed to date. We first propose a new DA framework DAFCC1 (Data Assimilation Framework based on C-Coupler2.0, version 1) for weakly coupled ensemble DA, which enables users to conveniently integrate a DA method into a model as a procedure that can be directly called by the model. DAFCC1 automatically and efficiently handles data exchanges between the model ensemble members and the DA method, and enables the DA method to utilize more processor cores in parallel execution. Based on DAFCC1, we then develop a sample weakly coupled ensemble DA system by combining the ensemble DA system GSI/EnKF and the coupled model FIO-AOW. This sample DA system and our evaluations demonstrate the effectiveness of DAFCC1 in both developing a weakly coupled ensemble DA system and accelerating the DA system.
Technical note: Effects of iron(II) on fluorescence properties of dissolved organic matter at circumneutral pH

Abstract. Modern fluorescence spectroscopy methods, including excitation-emission matrix (EEMs) spectra parsed using parallel factor analysis (PARAFAC) statistical approaches, are widely used to characterize dissolved organic matter (DOM) pools. The effect of soluble reduced iron, Fe(II), on EEM spectra can be significant, but is difficult to quantitatively assign. In this study, we examine the effects of Fe(II) on the EEM spectra of groundwater samples from an anaerobic deltaic aquifer containing up to 300 mg/L Fe(II), located a few kilometers from the ocean, adjacent to the Fraser River in Richmond, British Columbia, Canada. We added varying quantities of Fe(II) into groundwater samples to evaluate Fe(II)-DOM interactions. Both the overall fluorescence intensity and the intensity of the primary peak, a humic-like substance at excitation/emission wavelengths 239/441–450 nm (Peak A), decreased by approximately 60 % as Fe(II) concentration increased from 1 to 306 mg/L. Furthermore, the quenching effect was non-linear and proportionally stronger at Fe(II) concentrations below 100 mg/L. This non-linear relationship suggests a static quenching mechanism. In addition, DOM fluorescence indices are substantially influenced by the Fe(II) concentration. With increasing Fe(II), the fluorescence index (FI) tends to shift to a more microbial-derived origin, and both the humidification index (HIX) and freshness index (FrI) indicate more freshly produced DOM. Nevertheless, the 13-component PARAFAC model showed that the component distribution was relatively insensitive to Fe(II) concentration, and thus, PARAFAC may be a reliable method for obtaining information about the DOM composition and its redox status in Fe(II)-rich waters. By characterizing the impacts of up to 300 mg/L Fe(II) on EEMs using groundwater from an aquifer which contains similar Fe(II) concentrations, we advance previous works which characterized impacts of lower Fe(II) concentrations (less than 2 mg/L) on EEMs.

Abstract. The 2015–2016 El Niño event ranks as one of the most severe on record in
terms of the magnitude and extent of sea surface temperature (SST) anomalies
generated in the tropical Pacific Ocean. Corresponding global impacts on the
climate were expected to rival, or even surpass, those of the 1997–1998 severe
El Niño event, which had SST anomalies that were similar in size.
However, the 2015–2016 event failed to meet expectations for hydrologic change
in many areas, including those expected to receive well above normal
precipitation. To better understand how climate anomalies during an El
Niño event impact soil moisture, we investigate changes in soil moisture
in the humid tropics (between ±25∘) during the three most
recent super El Niño events of 1982–1983, 1997–1998 and 2015–2016, using data
from the Global Land Data Assimilation System (GLDAS). First, we use in situ
soil moisture observations obtained from 16 sites across five continents to
validate and bias-correct estimates from GLDAS (r2=0.54). Next, we
apply a k-means cluster analysis to the soil moisture estimates during the
El Niño mature phase, resulting in four groups of clustered data. The
strongest and most consistent decreases in soil moisture occur in the Amazon
basin and maritime southeastern Asia, while the most consistent increases occur
over eastern Africa. In addition, we compare changes in soil moisture to both
precipitation and evapotranspiration, which showed a lack of agreement in
the direction of change between these variables and soil moisture most
prominently in the southern Amazon basin, the Sahel and mainland southeastern Asia.
Our results can be used to improve estimates of spatiotemporal differences
in El Niño impacts on soil moisture in tropical hydrology and ecosystem
models at multiple scales.
A line-integral-based method to partition climate and catchment effects on runoff
Authors: Zheng Mingguo
Published: May 2020

Abstract. It is a common task to partition the synergistic impacts of drivers in the
environmental sciences. However, there is no mathematically precise solution
to this partition task. Here I present a line-integral-based method, which
addresses the sensitivity to the drivers throughout the drivers'
evolutionary paths so as to ensure a precise partition. The method reveals
that the partition depends on both the change magnitude and pathway (timing
of the change) but not on the magnitude alone unless used for a linear
system. To illustrate this method, I applied the Budyko framework to
partition the effects of climatic and catchment conditions on the temporal
change in the runoff for 19 catchments from Australia and China. The
proposed method reduces to the decomposition method when assuming a path in
which climate change occurs first, followed by an abrupt change in catchment
properties. The proposed method re-defines the widely used sensitivity at a
point as the path-averaged sensitivity. The total-differential and the
complementary methods simply concern the sensitivity at the initial and/or
the terminal state, so they cannot give precise results. Although the
path-averaged sensitivities varied greatly among the catchments, they can be
readily predicted within the Budyko framework. As a mathematically accurate
solution, the proposed method provides a generic tool for conducting
quantitative attribution analyses.
