Multi language Email Classification Using Transfer learning

In recent years Artificial Intelligence has become a core part of many businesses, from manufacturers to service providers, AI can be found helping to improve business processes as well as providing customized experiences and support for the customers. Natural language processing gives computers the ability to understand human language, recent breakthroughs in multilingual models bring us closer to overcome language barriers and achieve various tasks regardless of the language. This brings to companies the opportunity to process data and provide services to customers regardless of their language. In this dissertation, we review the progress of NLP towards multilingual text classification, our results suggest that using a machine translation to augment our corpora is a suitable approach to fine-tune multi-language models like XLM-Roberta, obtaing better results than zero-shot approaches. Our results also suggest that in domain pre-training can help to increase the performance of the classification for both monolingual and multi-language classifiersDissertation presented as the partial requirement for obtaining a Master's degree in Information Management, specialization in Knowledge Management and Business Intelligenc

Determinants of the degree of innovation in the industries listed on the B3

The study aims to identify the determinants of the degree of innovation of industries listed on the Brazilian Stock Exchange - B3. To this end, it used as sample 129 industries that trade their shares on the B3. From the principal component analysis, it was found that the innovation indicators are combined into two distinct factors. Therefore, it can be said that the degree of innovation of the firms takes into account the combination of indicators referring to the innovation strategies of exploitation and exploration, and, by encompassing two distinct factors, it is valid to mention that the degree of innovation has a two-dimensional character, suggesting the existence of a synergy between the innovation strategies

URBANTB group: Patrícia Soares (Representative of the consortium), Mário Carreira, Sofia Pereira, Catarina Alves, Filipe Alves, Ana Rodrigues, Ana Moreira, Márcia Cardoso, Sandra Mota, Ana Gomes, Liliana Ferreira, Marta Lopes, Isabel Correia, Juan Rachadell, Maria Gameiro, Ângela Dias, Manuel Pereira, Jorge Gonçalves, Maria Gonçalves, Adriana Taveira, Celene Neves, Lucinda Silva, Maria Mendes, Maria Teixeira, Maria Pereira, Milena Piedade, Antónia Teixeira & Carlos Carvalho.Background: Diagnosis delay contributes to increased tuberculosis (TB) transmission and morbimortality. TB incidence has been decreasing in Portugal, but median patient delay (PD) has risen. Symptom valorisation may determine PD by influencing help-seeking behaviour. We aimed to analyse the association between symptom valorisation and PD, while characterising individuals who disregarded their symptoms. Methods: A cross-sectional study was conducted among TB patients in Lisbon and Oporto in 2019 - 2021. Subjects who delayed seeking care because they did not value their symptoms or thought these would go away on their own were considered to have disregarded their symptoms. PD was categorised using a 21-day cut-off, and a 30-day cut-off for sensitivity analysis. We estimated the effect of symptom valorisation on PD through a directed acyclic graph. Then, a multivariable regression analysis characterised patients that disregarded their symptoms, adjusting for relevant variables. We fitted Poisson regression models to estimate crude and adjusted prevalence ratios (PR). Results: The study included 75 patients. Median PD was 25 days (IQR 11.5-63.5), and 56.0% of participants had PD exceeding 21 days. Symptom disregard was reported by 38.7% of patients. Patients who did not value their symptoms had higher prevalence of PD exceeding 21 days compared to those who valued their symptoms [PR 1.59 (95% CI 1.05-2.42)]. The sensitivity analysis showed consistent point estimates but wider confidence intervals [PR 1.39 (95% CI 0.77-2.55)]. Being a smoker was a risk factor for symptom disregard [PR 2.35 (95% CI 1.14-4.82)], while living in Oporto [PR 0.35 (95% CI 0.16-0.75)] and having higher household incomes [PR 0.39 (95% CI 0.17-0.94)] were protective factors. Conclusions: These findings emphasise the importance of symptom valorisation in timely TB diagnosis. Patients who did not value their symptoms had longer PD, indicating a need for interventions to improve symptom recognition. Our findings also corroborate the importance of the socioeconomic determinants of health, highlighting tobacco as a risk factor both for TB and for PD.This work was supported by the Fundação para a Ciência e Tecnologia (FCT, Portugal) [Grant: PTDC/SAU-PUB/31346/2017].

Cuidados biomédicos de saúde em Angola e na Companhia de Diamantes de Angola, c. 1910-1970

Pretende-se caracterizar a prestação de cuidados biomédicos em Angola durante a atividade da Companhia de Diamantes de Angola. Uma análise comparativa de políticas e práticas de saúde pública de vários atores coloniais, como os serviços de saúde da Companhia, sua congénere do Estado e outras empresas coloniais, revelará diferenças de investimento na saúde, isto é, instalações e pessoal de saúde, e tratamentos. Este escrutínio bem como as condições de vida iluminarão o carácter idiossincrático e central dos serviços de saúde da Companhia em termos de morbimortalidade em Angola, e a centralidade destes para as representações de um império cuidador

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

The Mississippian Toca da Moura-Cabrela Basin (SW Ossa-Morena Zone, Portugal): sedimentation and palaeoenvironments

Introduction and Geological context The Iberian Massif is the most southwestern domain of European Variscides, displaying an internal organization that allows to identify several palaeogeographic zones, among which the Ossa-Morena Zone (OMZ) that is included in the hinterland domains of this Massif. The Carboniferous sedimentation in the hinterland is restricted to small basins, controlled by the tectonic setting. During early Mississippian, the transitional subduction-collision process seems to be responsible for the genesis of syn-orogenic basins in the OMZ, such as the Toca da Moura-Cabrela Basin (TMCB) along the southwest boundary of the OMZ. The TMCB is characterized by a volcano-sedimentary complex with a Late Tournaisian-Late Visean age, which is the object of this study. Sedimentation ages Samples from several sections of the TMCB were taken, processed for palynology and analysed under transmitted light microscopes. The observed organic particles were invariably dark grey to black, indicative of a very high thermal maturation. From the 4 oxidized samples, only 2 provided recognizable palynomorphs. The two samples derived from carbonate-bearing shale/siltstone outcrops in the northern part of the Cabrela sub-basin, thus far unstudied. One provided a fairly diversified late Tournaisian spore assemblage. The poor preservation frequently hampered the identification to species level, but several stratigraphically relevant taxa were observed. The other productive sample allowed only to determine a general Tournaisian-Visean age. Several thin sections were produced from the 3 samples taken for micropaleontological purposes, from the rare non-remobilized carbonates in the TMCB (interbedded in the turbidite succession). The occurrence of foraminifera, such as the rare Paraarchaediscus, Pojarkovella, Hemiarchaediscus? stilus together with widespread Uralodiscus spp. in this association indicates the subzone MFZ11B (mid Visean). Sedimentology and palaeoenvironments Along the edges of the Cabrela sub-basin, conglomerate beds outcrop at the bottom of succession. In the northern edge, the conglomerate lithoclasts derived from early Palaeozoic units of the OMZ, currently outcropping to the East and North (and partially to the South) of the basin. Clasts from the South Portuguese Zone are notably absent. In the southern edge, several carbonate clasts are present, frequently dolomitized. The remainder of the sedimentary rocks are dominated by grey to black shales interbedded with siltstones and fine sandstones (rarely coarser-grained), which are interpreted as low-density turbidite deposits. Locally the coarser-grained intervals are dominated by volcanic-derived clasts. Palaeocurrent study on turbidite deposits from TMCB indicates: (1) the dominance of palaeocurrents to the SW quadrant in the Cabrela sub-basin (northern part); (2) great dispersion in the northern domains of Toca da Moura sub-basin (central area), although with dominance to the western quadrant; and (3) transport to the N quadrant in the southern part. The palynofacies analysis showed varying amounts of organic particle types, with AOM and phytoclasts as dominants types – up to 73% and 89% respectively. Phytoclasts are in most instances black and opaque, of several sizes. Palynomorphs were present in all samples, but always subordinate, up to 11%. These were composed of essentially sporomorphs and extremely rare acritarchs. The TMCB samples plot in fields I, VI, VII and IX of the Tyson diagram, with a greater prevalence in fields corresponding to suboxic to anoxic settings (shelf to basin). Ichnology and ecological traits Bioturbation was found in simple tiering profiles in three of the studied sections, namely Corte Pereiro, Monte Novo and “Buraco”. In Corte Pereiro, the upper 9 m of the succession show thin-bedded turbidites composed mainly by Td-Te Bouma intervals, dominated by dark pelites with rare, cm-thick intercalations of fine-to-very fine sandstones and siltstones with convolute, oblique and parallel lamination, sole marks including flute casts and, occasionally, hypichnial bioturbation. Slumps are also visible at the outcrop-to-bedding scales. Bioturbational tiering is condensed and divided in post- and pre-depositional suites: horizontal, slightly curving, unlined, evenly-sized meniscate burrows (Taenidium satanassi), sub-horizontal to oblique winding, lined burrows (Palaeophycus isp.) and the millimetric sub-horizontal winding burrow with levees Helminthoidichnites isp. (post-depositional); rare wide spiral, single-whorled Spirodesmos archimedeus and the irregular burrow network Megagrapton irregulare graphoglyptids, besides bowl-shaped vertical burrows of Bergaueria isp. (pre-depositional). Both tiers are intersected by 3D tunnel branching systems (Chondrites isp.) extending downwards to the organic-rich shales and filled by pyrite. Diversity of behaviours in deep sea deposits reached a relative maximum by the Mississippian. This is not the case in the TMCB. Diluted turbidite events in a succession otherwise dominated by black shales, showing simple shallow tiers and low ichnodiversity, with the presence of opportunistic bioturbation events dominated by simple, mobile deposit-feeding strategies and the rare presence of pre-depositional graphoglyptid-bearing suites and the deeper activity of a non-vagile organism below the redox boundary, reveal a hostile, unstable, quickly oxygen-depleting environment with high sedimentation rates. Turbidites were responsible for the short-term colonization windows, episodically increasing in oxygen the bottom and interstitial waters of these organic-resourceful substrates, but where oxygen-depletion was faster than the bioturbation rate during the quiescent deposition. Moreover, the post-depositional suite is dominated by only three facies crossing, simple deposit-feeding ethologies in low ichnofabric indices, indicative of a low-energy slope environment and being closer to shelfal expressions of the Zoophycos Ichnofacies

Perante a Pneumônica: a epidemia e as respostas das autoridades de saúde pública e dos agentes políticos em Portugal (1918-1919) Tackling the Flu: the epidemic and the responses from the public health officers and the political agents in Portugal (1918-1919)

A epidemia de gripe pneumónica ocorreu em Portugal num momento em que o país que enfrentava enormes dificuldades de natureza económica, política e sanitária. Chega a um país rural e pobre, envolvido na Grande Guerra de 1914-18, e que se debate com a carência de géneros e a carestia de vida, e com uma fortíssima crise social e política. Apesar de o país estar habituado a sucessivas epidemias, o carácter imprevisto e violento da pneumónica (estima-se que tenha provocado quase 140 mil mortos num país com cerca de 6 milhões de habitantes) fez com que a resposta dos agentes políticos e sanitários fosse marcada por factores ligados à conjuntura (crise económica, social e política) e de tipo estrutural (condições higiénicas e sanitárias deficientes, falta de meios em capital económico, de médicos e de medicamentos, impotência do conhecimento médico para debelar a epidemia).<br>The Spanish influenza epidemic occurred in Portugal when this country faced enormous economic, political and sanitary problems. The country was poor, living mainly from agriculture and was involved in the First World War. There were food shortages, a high cost of living, as well as a strong social and political crisis. Although people were used to deal with successive epidemic diseases, the sudden and violent character of the Spanish influenza took everybody by surprise. According to some estimation it killed about 140 thousand in a 6 million person's countryThe answer of the political and sanitary agents was marked by contextual factors (the economic, social and political crisis) as well as by structural ones (very poor hygienic and sanitary conditions, lack of financial resources, of doctors and medicines, impotence of medical knowledge in dealing with the pandemic)
