ENTRE TENDAS E ESCOLAS: desafios para a educação formal do povo cigano no Distrito Federal
Authors: Reses Erlando Da Silva , Pinel Walace Roza , Perpetuo Lenilda Damasceno
Published: May 2019

O presente artigo é fruto de uma investigação social, iniciada no mestrado e continuada por meio do Doutorado em Educação na Universidade de Brasília (UnB), o qual procura trazer à tona a realidade em que vivem os Ciganos Calon em Sobradinho/DF, no seu processo de educação e luta pela posse da terra. Comunidade que passa por um processo de mudanças culturais e transita de uma situação de nomadismo para uma de sedentarismo. Devido a sua cultura de vida livre, encontram inúmeras dificuldades de adaptação ao modelo de sociedade proposta. Sendo assim, a moradia fixa e a posse da terra ainda se tratam de espaços antagônicos aos seus modos históricos de vida. Desse modo, esta pesquisa aborda o percurso histórico-cultural dos povos ciganos, contribuindo para a análise e a compreensão das associações entre etnicidade cigana e a luta, buscando identificar uma política intercultural de educação amparada pelos Direitos Humanos, a qual permita a efetiva inclusão social e educacional dos povos ciganos no Distrito Federal. De caráter qualitativo, temos como base teórica o materialismo histórico dialético, o qual investiga as representações sociais acerca do povo cigano e como essas representações, por sua vez, influenciam nos seus conflitos étnicos e territoriais.
Урожайность сои в зависимости от накопления сухой биомассы в условиях южной лесостепи Западной Сибири
Authors: Бендина Яна Борисовна
Published: May 2019

Соя является наиболее важной зернобобовой культурой во всем мире. Существенное влияние на скорость образования сухого вещества надземной биомассы растения оказывают экологические условия, особенно почвенные и метеорологические. Сильно выраженная континентальность климата основных сельскохозяйственных районов Сибири обуславливает повышенные требования к возделываемым сортам. Исследования проводили в 2013 – 2015 гг. на примере растений сои сорта Эльдорадо. Изучены накопление и распределение сухой биомассы сои с последующей математической обработкой данных, корреляционным и вариационным анализами. Показано значительное влияние условий периода вегетации как на накопление сухой биомассы растениями сои, так и на её урожайность (вклад условий года составил 99,6 и 94,2 % соответственно). Подтверждением этого служат данные корреляционного анализа — период «всходы – цветение» характеризовался тесной сопряженностью гидротермического коэффициента с накоплением сухой биомассы вегетативной частью растений (r = 0,478; 0,998) и с генеративной частью в фазе созревания (r = 0,817). В последующем развитии растений можно говорить о конкуренции между вегетативной и генеративной частями растений, что выражается в отрицательной сопряженности как указанных частей между собой (r = –0,993), так и урожайности с вегетативной частью в период созревания (r = –0,500). Исследуемый сорт Эльдорадо характеризовался как стабильный в меняющихся условиях окружающей среды (σ2d < 1) со слабой реакцией урожайности на улучшение условий выращивания (bi < 1), что соответствует экстенсивному типу. Сорт рекомендован для возделывания в условиях южной лесостепи Западной Сибири.

Authors: Himelbrant D. E. , Stepanchikova I. S. , Ahti T. , Neshataeva V. Yu.
Published: May 2019

The first lichenological inventory in Koryakia has resulted in the list of 315 species reported from Parapolsky Dale, within and in vicinities of the Koryak State Reserve. Altogether 46 species are published from the Kamchatka Territory for the first time, including Lecanographa grumulosa new to Russia, East Asia and Beringia; Cercidospora trypetheliza, Lecania dubitans, Pertusaria borealis, Piccolia ochrophora, Protoparmelia cupreobadia, Rimularia badioatra and Strangospora moriformis new to Russian Far East; Abrothallus bertianus, Cladonia strepsilis, Physciella melanchra, Rimularia badioatra, Sclerococcum parasiticum, Sphinctrina leucopoda and Strangospora moriformis new to Beringia. The lichen diversity of the study area is relatively poor due to natural reasons. Comparison with neighboring regions (Kamchatka Peninsula, Chukotka, Magadan Region, Yakutia and Alaska) shows that the lichen flora of Parapolsky Dale contains almost no specific species. The majority of the species recorded here are also known from neighboring regions, especially Alaska and Kamchatka Peninsula.

Post-Aestivation Puddling by Female Chazara Briseis Larnacana (Oberthür, 1909) and Maniola Cypricola (Graves, 1928) (Lepidoptera: Nymphalidae, Satyrinae): Influences and Implications
Authors: John Eddie , Dennis Roger L. H.
Published: May 2019

Mud-puddling by female Lepidoptera is rarely reported. In this paper, post-aestivation puddling by females of Chazara briseis larnacana and Maniola cypricola as a possible means of enhancing fecundity is discussed. Both are long-lived Cyprus endemics that mate in spring
but undergo arrested ovarian development pending the return of more favourable conditions for larval survival in the autumn. The delay between mating and ovipositing appears to indicate a need for post-aestivation females to puddle in order to replenish depleted resources initially gained
at the larval stages and through the transfer of minerals and nutrients via the spermatophore at mating. A first known report of marine (seawater) puddling by C. briseis is also discussed, as is the importance of Dittrichia viscosa as a late-season nectar resource for many species
of butterfly.

The Analysis of Tuberculosis Funds Efficiency on High Burden Countries
Authors: Sihaloho Estro Dariatno , Siregar Adiatma Y.M
Published: May 2019

Tuberculosis remains a major global health problem and ranks as the second leading cause of death from infectious disease worldwide. Countries devote their budgets to overcome the tuberculosis problem. An efficient use of these budgets will arguably reduce the number of tuberculosis cases and eventually give a positive impact to the economy. This paper aims it aims to estimate the technical efficiency scores of tuberculosis funds on high-burden countries by using Data Envelopment Analysis(DEA) method. Further, this study analyzes other environmental factors that are crucial to increase the efficiency scores by using Tobit method. DEA shows that some countries exhibit high efficiency scores while others exhibit low efficiency scores. It also informs how countries use funds to maximize their results. Meanwhile, the Tobit estimation shows that taxing cigarettes and committing budgets to control tobaccos have positive marginal effects on technical efficiency scores.

GPS use negatively affects environmental learning through spatial transformation abilities
Authors: Ruginski Ian Tanner , Creem-Regehr Sarah , Stefanucci Jeanine , Cashdan Elizabeth
Published: May 2019

Research has established that GPS use negatively affects environmental learning and navigation in laboratory studies. Furthermore, the ability to mentally rotate objects and imagine locations from other perspectives (both known as spatial transformations) is positively related to environmental learning. Using previously validated spatial transformation and environmental learning tasks, the current study assessed a theoretical model where long-term GPS use is associated with worse mental rotation and perspective-taking spatial transformation abilities, which then predicts decreased ability to learn novel environments. We expected this prediction to hold even after controlling for self-reported navigation ability, which is also associated with better spatial transformation and environmental learning capabilities. We found that mental rotation and perspective-taking ability fully account for the effect of GPS use on learning of a virtual environment. This relationship remained after controlling for existing navigation ability. Specifically, GPS use is negatively associated with perspective-taking indirectly through mental rotation; we propose that GPS use affects the transformation ability common to mental rotation and perspective-taking.

To Move Home or Move On? Investigating the Impact of Recovery Aid on Migration Status as a Potential Tool for Disaster Risk Reduction in the Aftermath of Volcanic Eruptions in Merapi, Indonesia
Authors: Muir Jonathan A. , Cope Michael R. , Jackson Jorden E. , Angeningsih Leslie R.
Published: May 2019

Disasters are associated strongly with forced migration. Indeed, migration is a standard survival strategy for those facing disruptions of this kind. Such is the case with Mt. Merapi, Indonesia, where a series of eruptions occurred in 2010. Mechanisms related to forced migration in such scenarios are fairly well understood, yet it remains less clear what factors may influence return migration. Given local interest in facilitating resettlement out of hazardous areas as a means of risk reduction, we seek to better understand the extent to which recovery aid may create incentives for households to move on rather than move home. We draw upon data collected from a pilot study in the aftermath of the 2010 eruptions and use multinomial logistic regression models to explore the influence of various forms of aid on migration status. Of the various forms of aid considered, financial recovery aid provided to households was consistently associated with moving on. The combination of financial recovery aid with remittances resulted in an association with having moved on that was even stronger than just receiving financial recovery aid. Ultimately, analyses of "aid packages'" suggest that a combination of most, if not all, of the aid was relatively more effective in fostering resettlement, suggesting that while food and health recovery aid as well as remittances may not have been sufficient in and of themselves to increase resettlement, they may enhance the effect of financial recovery aid.
The Importance of Ethical Conduct by Penetration Testers in the Age of Breach Disclosure Laws.
Authors: Thomas Georg , Burmeister Oliver , Low Gregory
Published: May 2019

Across the globe, there has been a noticeable increase in the adoption of breach disclosure laws that are designed to protect the privacy of individuals. To validate the security controls implemented by an organisation to protect sensitive data, penetration testers are often engaged to test the security of information systems and to report any vulnerabilities. Using an interpretivist, constructivist approach, this article reports on a pilot study that compares USA and Australian approaches to ethical hacking. The need for regulation of ethical hacking to help protect organisations from unethical conduct was a recurring theme. With the changes in privacy regulations across the world, unauthorised disclosure of personal and privileged information could result in significant consequences. This paper explores the importance of ethical conduct by penetration testers based on empirical research and the potential for misuse of information.
Safeguarding or Surveillance
Authors: Cowden Stephen , Picken Jonathan
Published: May 2019

This paper seeks to critically explore the construction of the PREVENT Counter-Terrorism initiative within Social Work in the UK, and to consider the implications this has for Social Work.  We begin by discussing the conceptualisation of ‘radicalisation’ in the work of Arun Kundnani, one of the leading critics of PREVENT, pointing to the limitations of this as a means of grasping the nature of Salafi-Jihadi groupings. We then move to a discussion of the development of Counter-terrorism policy in the UK looking at the way the 2015 legislative guidance has re-situated radicalisation from a ‘security’ issue to a ‘safeguarding’ issue.  We see this as significant for the way it has facilitated Social Work being directly drawn into the orbit of PREVENT and CHANNEL, with radicalisation being re-constructed as part of Social Work’s concern with the vulnerability of children and young people involved in wider forms of exploitation, including CSE.  We consider the reception of this shift within Social Work as well as looking at evidence into how this working in practice.  We then consider challenges to this ‘safeguarding’ paradigm, which argue that this has involved Social Work being drawn into the ideological monitoring of Muslim communities; a ‘surveillance’ paradigm.  We conclude by arguing for a critical defence of a safeguarding approach based on the harms which fundamentalist violence clearly represents to children and young people.
Identification of Earthworm Species in Uruguay Based on Morphological and Molecular Methods
Authors: Jorge Escudero Gabriella , Lagerlöf Jan , Martínez Debat Claudio , Pérez Carlos Alberto
Published: May 2019

Molecular techniques could aid earthworm species identification, especially when morphological characters are not taxonomically informative, or difficult to discern. No previous study has investigated molecular-based methods for earthworm taxonomy in Uruguay. The present study aimed to make a first approach using DNA barcoding as a tool to smoothen the way towards determining the earthworm richness in Uruguay. This study was based on an earthworm collection, identified both by morphological characters and molecular techniques, from samplings from different agricultural soils in Montevideo and Paysandú, Uruguay. Adult individuals were identified by external morphology following available descriptions of regional earthworms. From each morphological group a representative sample was selected for genomic DNA extraction, mitochondrial COI region amplification and sequencing. Sequences obtained were subject to BLAST searches and compared to sequences available in GenBank. Eight out of 11 sequenced exotic species were fully identified and matched morphological characters and molecular information; two were less consistent, with lower sequence similarity percentage; and one could not be fully identified due to lack of close related sequences in GenBank. While most exotic species had representative sequences annotated in GenBank, this was only the case for one native species, highlighting the need to develop this important area at a regional level. This study could kick-start an innovative research program, since there are limited records of earthworm samplings in Uruguay and no identification of species by DNA sequences from national studies.
Effect of Condensed Tannins in Lotus uliginosus cv. E-Tanin and/or Extracts of Quebracho and Chestnut in Carcass and Lamb Meat
Authors: Luzardo Santiago , Mederos América , Brito Gustavo
Published: May 2019

The effect of condensed tannins (CT) in the pasture (Lotus uliginosus cv. E-Tanin) and/or quebracho and chestnut extracts on lamb carcass and meat quality was evaluated. Two experiments were conducted in consecutive years with 60 crossbreed lambs each year. The animals were stratified by live weight (LW) and randomly assigned to the treatments: white clover grazing (WC); WC plus concentrate supplementation (WC + C); WC plus concentrate supplementation and quebracho and chestnut extract (WC + C + CT); Lotus uliginosus grazing (E-Tanin); E-Tanin plus concentrate supplementation (E-Tanin + C); E-Tanin plus concentrate supplementation plus quebracho and chestnut extract (E-Tanin + C + CT); with two repetitions each year. Pasture type affected loin weight, which was greater (P < 0.05) in lambs grazing WC than E-Tanin. Meat color redness (a*) was greater (P < 0.05) in supplemented treatments with C (with or without CT) than those exclusively grazing. Intramuscular fat content was not affected (P > 0.05) by the pasture, the supplementation, or the year. The proportion of dihomo-gamma-linolenic acid (C20:3-n6) was greater (P < 0.05) in lambs grazing E-Tanin compared to WC. Supplementation affected (P < 0.05) the saturated (SFA) and monounsaturated fatty acids (MUFA) proportions, and the omega 6:omega 3 ratio. Estimation of dry matter intake under grazing conditions would allow a better understanding of the effect of CT on carcass and meat quality.

Thermal-fatigue resistant work rolls for hot rolling mills
Authors: Goryany Vyacheslav , Myronova Olga , Buch Johannes , Buch Alexander , Stein Frank
Published: May 2019

Cyclic temperature changes in the working layer of a roll during hot rolling cause thermal stress which leads to damage on the surface layer of the roll due to thermal fatigue. The pre-conditions of crack initiation are described. The intensity of crack propagation could be influenced by optimizing the chemical composition and physical-mechanical properties of the material on the working layer. This reduces the tendency of the material with respect to damage due to thermal fatigue and extends the lifetime of the rolls. The microstructure as well as the operational characteristics of the developed HSS working rolls resistant to thermal fatigue are presented.

Published: May 2019

This research on the stiffness of glass fiber reinforced plastics (GFRP) pipes constructed according to various types of winding patterns and under varied loading conditions, proposes a model of stiffness degradation for GFRP pipes and the parameters for a model of stiffness degradation. Based on a hoop winding GFRP pipe fatigue test, it was found that the stiffness reduction rate of the first half a million cycles is 0.67 times that of the last 500,000 cycles when maximum alternating displacement is 5 % of the diameter of the GFRP pipe. For the same type of winding GFRP pipe, the stiffness reduction rate at a maximum alternating displacement of its diameter'of 10 % and 15 % yields 1.34 and 1.59 times the stiffness reduction rate of a GFRP pipe with an alternating displacement maximum of its diameter of 5 %, respectively. For GFRP pipes of varied types of winding modes, when the maximum alternating displacement is 5 % of the diameter of a GFRP pipe, the rate of stiffness degradation of the helical winding GFRP pipe and hoop-helical combined winding GFRP pipe is 1.50 and 1.28 times that of a hoop winding GFRP pipe, respectively.

Gas hydrates – history of discovery
Authors: Goshovskyi S. V. , Zurian Oleksii
Published: May 2019

The literature sources dealing with the history of gas hydrate studies and discovery of possible existence of gas hydrate deposits in natural conditions were analyzed. They contain facts proving that within 1966 and 1969 the conditions for formation of hydrates in porous medium were researched at the Department of Gas and Gas Condensate Deposits Development and Exploitation of Gubkin Russian State University of Oil and Gas. The first experiments were set up by the Ukraine-born Yurij F. Makogon, Department Assistant Professor. The results proved possibility of formation and stable existence of gas hydrates in earth’s crust and became a scientific substantiation of natural gas hydrate deposits discovery. In 1969 the exploitation of Messoyakha deposits in Siberia started and it was the first time when the natural gas was derived directly from hydrates. The same year that invention was officially recognized and registered. Following the comprehensive international expert examination the State Committee on Inventions and Findings of the USSR Council of Ministers assumed that the citizens of the USSR Yurij F. Makogon, Andrej A. Trofimuk, Nikolaj V. Cherskij and Viktor G. Vasilev made a discovery described as follows: “Experiments proved previously unknown ability of natural gas to form deposits in the earth’s crust in solid gas hydrate state under definite thermodynamic conditions (Request dated March 19, 1969)”. The authors were presented with diplomas on March 4, 1971. From then onwards the issue of natural gas hydrates existence was widely researched all around the world. In 1985 Yurij F. Makogon became a Professor. Since 1973 he was a head of the gas hydrate laboratory in the All-Russian Scientific Research Institute of Natural Gases and Gas Technologies. Within 1974–1987 he was a head of the gas hydrate laboratory in Oil and Gas Research Institute RAS. In 1992 he was invited by one of the largest universities of the USA to arrange modern laboratory for gas hydrate study. The laboratory was created in the Texas University, USA and in 1995 Yurij Makogon became its head. As far as interest in gas hydrates increases Yurij F. Makogon reports at 27 international congresses and conferences, gives lectures in 45 world leading universities, functions as an academic adviser and participates in different international programs on research and exploitation of gas hydrate deposits in USA, Japan and India. The heritage of the scientist includes 27 patents, eight monographs (four of them were translated and published in the USA and Canada) and more than 270 scientific articles.

Taking an experimental design approach, this study investigates how narrative perspective (Ingroup Perspective vs. Outgroup Perspective) interacts with intergroup interaction depiction (Positive vs. Negative) in transgender-related media content to redirect people’s attitudes toward transgender people, transportation, and elevation responses. The findings reveal that the outgroup perspective is more likely to elicit 1) positive attitudes toward the featured transgender character and the transgender outgroup; 2) transportation; and 3) meaningful affect, mixed affect, and motivational responses. However, the positive depiction of transgender-cisgender intergroup interaction only prompts positive attitudes toward the transgender character, meaningful affect, and physical responses. Implications of such intergroup communication strategies in public interest communications are discussed.

The remote sensing data, such as sea surface temperature & chlorophyll concentration obtained from various satellites are utilized by Indian National Centre for Ocean Information Services (INCOIS) to provide Potential Fishing Zone (PFZ) advisories to the Indian fishing community which plays a vital role in national GDP. The data on Sea Surface Temperature (SST) is retrieved regularly from thermal-infrared channels of NOAA-AVHRR and chlorophyll concentration (CC) from optical bands of Oceansat-II and MODIS Aqua satellites for the identification of Potential Fishing Zones (PFZ) in Indian water. PFZ information has certain limitations, such as it can't predict the type of fish available in the notified fishing zone. In this dissertation, I have worked towards the development of short-term Hilsa shad predictive capabilities in a sustainable way. An effort has been taken to categorize all essential biological, environmental and climatic signals that have a direct or indirect impact on the Hilsa shad distribution. Remote sensing, ocean biogeochemical modelling, and statistical modelling approach have gained an increasing importance to study the marine ecosystems as-well-as for understanding the dynamics of the oceanic environment. Shad habitat has been studied from the geo-tagged fish catch data and oceanic/ecological indicators as predictor variables. For short-term prediction, the variables have been derived from a biophysical model, configured at INCOIS, using Regional Ocean Model System (ROMS) and remote sensing data. Using generalized additive model (GAM) Catch per Unit Effort (kg h?1) has been calculated as a response variable. Probability maps of predicted habitat with no fishing zone information have been generated using geographic information system.

Background: Neurovascular malformations (NVMs) in pediatric population are highly challenging to manage and treatment options include open surgery, endovascular therapy, and radiosurgery or combined. Recently, there has been a gradual shift from conventional surgical approach toward endovascular therapies with increasing availability of technical expertise and gadgetry. Objective: We aimed to study the clinical profile and immediate outcome of children with NVMs, who underwent endovascular therapy. Materials and Methods: This retrospective observational study was conducted in a tertiary care center in South India between February 2017 and August 2018. We included children admitted in pediatric intensive care unit (PICU) with NVM and needed neuroradiological intervention. Children with thromboembolism or other NVMs who did not require intervention were excluded from the study. Data on clinical profile, endovascular procedure done, supportive therapy given, and immediate outcome were collected and analyzed. Results: Of 1615 children admitted in PICU, 13 had NVM (0.8%), of which five had arteriovenous malformation (AVM), three had vein of Galen arteriovenous malformation (VGAM), one had VGAM with dural AVM, one had acquired carotid-cavernous fistula, two had berry aneurysm, and one had mycotic aneurysm. VGAM presented as hydrocephalus, whereas AVM and aneurysm as intracranial hemorrhage. Endovascular embolization was done using platinum detachable coils, onyx, N-butyl cyanoacrylate glue, and coil assist stents. One child needed decompressive craniectomy and another child needed extraventricular drainage. Four children needed pre-procedure ventilation and seven children needed prolonged post-procedure ventilation. Mortality was 15%; and among the survivors, 72% had an uneventful recovery. One child had seizures and two had hemiparesis at discharge. Conclusion: Endovascular management is an effective intervention for pediatric NVM. Multidisciplinary team approach and good pediatric intensive care are important for successful outcome. Further studies with long-term follow-up are needed to assess the durability of endovascular therapy.

Introduction: Celiac disease (CD) may be an underlying cause of malnutrition. Aim: The objective of this study was to find out the seroprevalence of CD in children suffering from severe acute malnutrition (SAM) in age group of 1–5 years. Materials and Methods: This was a prospective, observational, hospital-based study carried out at Malnutrition Treatment Centre attached with tertiary care pediatric hospital associated with the medical college of southern Rajasthan, from December 2017 to November 2018. A total of 110 children with SAM were enrolled and screened for CD on the basis of celiac serology (tissuetransglutaminase [tTg]-immunoglobulin A/G [IgA/IgG]). Results: Celiac serology was positivity in 30 (27.28%) cases; out of total 30 seropositive cases, 14 (46.66%) cases were seropositive for both tTg-IgA and IgG, while only tTg-IgA and only tTg-IgG were positive in 9 (30%) and 7 (23.33%) cases, respectively. Mean serotiter of serum tTg-IgA and IgG in seropositive cases was 134.01±198.74 and 49.05±25.74 unit/ml. Conclusions: High seroprevalence of CD in SAM should be taken as alert as CD may be an underlying cause and responsible for malnutrition. These children should be screened by celiac serology (tTg-IgA/IgG) to rule out CD.
Optimizing use of empirical antibiotics in late preterm neonates at risk of early-onset sepsis

Published: May 2019

Background: In sick neonates, we are posed to treat suspected or proven infection. However, the vast majority of newborn babies who are given antibiotics do not have any infection. Objective: The objective of this study was to optimize the use of empirical antibiotic therapy in late preterms who are asymptomatic with maternal risk and symptomatic neonates without maternal risk for early-onset sepsis (EOS) and to estimate the rate of risk increase in onset of symptoms in neonates exposed to maternal risk factor for EOS. Methods: In this descriptive study, late preterm neonates (34+0–36+6 weeks) who are asymptomatic at birth with and without maternal risk factor for EOS at birth were subjected to clinical assessment of sensorium, temperature, oxygenation status, perfusion, and skin color, starting after 1 h of initial stabilization till discharge from hospital. Sepsis screen (C-reactive protein and absolute neutrophil count) was obtained at 24 h and 48 h of age from these asymptomatic late preterms. Results: A total of 135 late preterm neonates (34+0–36+6 weeks) recruited during the study period were included for analysis. The presence of maternal risk factor for EOS has shown no statistical significance in relation to the presence of symptoms at birth odds ratio 0.66, 95% confident interval (0.24–1.8) p=0.42. Conclusion: In our study, as maternal risk factor for sepsis has shown no statistical significance in relation to the presence of symptoms at birth, antibiotic use can be restricted to only those babies who have clinical worsening over 24–48 h of observation and/or along with supportive evidence of positive sepsis screen and/or blood culture, irrespective of the presence or absence of maternal risk for EOS.
Reflexive metadiscourse in a corpus of Spanish bachelor dissertations in EFL
Authors: Navarro Gil Noelia
Published: May 2019

Academic English has often been described as a reader-oriented discourse, in which the structure, objectives and claims are made explicit and carefully framed. Metadiscourse markers help to build coherence and cohesion, and allow writers to guide their readership through their texts. Spanish EFL learners often transfer part of their L1 writing culture into their L2 texts. This is problematic because academic Spanish tends to show a slightly more reader-responsible style, and academic texts call for a high degree of disciplinarity: learners not only have to be aware of the conventions of the L2 regarding metadiscourse, but also of their own discipline. This article explores the use of reflexive metadiscourse in a learner corpus of bachelor dissertations written in English by Spanish undergraduates in medicine and linguistics, and compares the results with an expert corpus of research articles. The results show that overall both corpora contain similar frequencies of textual metadiscourse, but this is only true when we look at the results according to discipline. In spite of this quantitative similarity, there are cases of overuse and underuse in the learner corpus that highlight features of the bachelor dissertations genre, on the one hand, and EFL Spanish writing, on the other hand.
