Four new records of pleurocarpous mosses are reported for the first time for the State of Bahia: Phyllodon truncatulus (Hypnaceae), Trichosteleum brachydictyon, Sematophyllum tequendamense and Potamium lonchophyllum (Sematophyllaceae). These species were found in the Tropical Atlantic Rainforest situated in the South of Bahia

Additional contribution to the bryophyte flora of Chapada Diamantina National Park, State of Bahia, Brazil
This paper represents an additional contribution toward the knowledge of a bryophyte flora of Chapada Diamantina National Park in the State of Bahia, Brazil, in which are reported 27 species of mosses belonging to 22 genera and 14 families, and four species of liverworts belonging to four genera and three families. Most of these species seem to be restricted to this high altitude geomorphological complex area
Estimation of Gender wage Discrimination in the Portuguese labour market
Gender wage discrimination is a reality in the Portuguese labour markets although no study has been until now carried on to measure its dimension. We think that economists should contribute to the knowledge of the dimension and significance of this phenomenon by giving orientation for the definition of political measures towards its reduction. In this paper we measure the size of gender wage discrimination in the Portuguese labour market. Furthermore, we evaluate this measure for the five Portuguese main regions. In recent literature about the measurement of gender wage discrimination the Oaxaca decomposition and its developments is a commonly used approach. We extend this approach using bootstrap techniques for statistical inference purposes.
Modeling and Performance Evaluation of Bicycle-to-X Communication Networks
The growing connectivity of vehicles and Vulnerable Road Users, i.e., pedestrians and cyclists, allows to explore solutions based on wireless communication to support safety, efficiency and infotainment applications.However, there are few communication technologies that enjoy similar penetration ratios on cars, bicycles and pedestrians.WiFi is one of such technologies, as can be found in smart phones and in on-board hotspots.This thesis aims to characterize experimentally the wireless link performance and develop a model to estimate the received signal strength (RSS) between WiFi devices installed on bicycles and cars equipped with built-in WiFi APs.The RSS estimation model extends existing empirical models (e.g., the Log-Distance Path Loss model) by including the shadowing of the bicycle-and-cyclist system and of a vehicle.We first characterize the radiation pattern of antennas installed in several mounting points of a bicycle, in order to reduce the set of mounting points to be explored in future measurements.We then measured the radiation pattern of the bicycle and cyclist system, and the radiation pattern of a car with built-in and dedicated WiFi access points.Finally, we evaluate the performance of the model by comparing RSS estimates and measurements collected in selected interaction scenarios between bicycles and car: (i) bicycle overtaking a parked car, (ii) perpendicular crossing with LOS, and (iii) without LOS. We observed that 50% of the RSS estimates our model underestimates by less than are within 10 dBs of measured values about 50% of the RSSI values for the scenarios in LOS, and overestimates the RSSI values by more than 5 DBs about 75% of the RSSI values for the scenario containing obstructions
Bryophytes from some Caatinga areas in the state of Bahia (Brazil)
The caatinga is a deciduous and xerophilous vegetation that covers large areas in Brazil. An irregular rainfall with a marked dry period is a characteristic feature. This paper represents the first contribution to the knowledge of the bryoflora from caatinga vegetation in the State of Bahia. The survey was carried out in several areas from Bahia in which eigthteen species of bryophytes were found (15 mosses and 3 liverworts). The bryoflora from caatinga is composed mainly of generalists and xerophilous taxa, but even some hygrophilous species can be found. A number of species including Hyophiladelphus agrarius, Hyophila involuta, Calymperes palisotii ssp. richardii, Bryum argenteum, Entodontopsis leucostega, Octoblepharum albidum, Frullania ericoides also occur in other vegetation types. However, there are a number of species restricted to this type of vegetation, such as Helicophyllum torquatum and Riccia vitalii, at least in Bahia. Most moss species were acrocarpous with erect and short (short-turf) growth-form, whereas the foliose hepaticae were of incubous, and thallose forms
Variaçoes morfológicas do lóbulo em "lejeunea glaucescens" gott.: lejeuneaceae, hepaticopsida
Variaçoes morfológicas do lóbulo em Lejeunea glaucescens Gott. (Lejeuneaceae, Jung ermnanniophyta). Foram estudados exemplares de Lejeunea glaucescens Gott. no sentido de serem estabelecidos padróes morfológicos objetivando melhor delimitar esse táxon, sendo identificados 10 padróes de variaçáo nos lóbulos dos filídios. Análises desses padróes mostram que n~o há uma clara correlaçáo com as condiçóes ambientais
Adições à brioflora (Bryopsida) do Estado da Bahia, Brasil

In this paper are reported 18 species of mosses belonging to 16 genera and 12 families (Archidiaceae, Orthotrichaceae, Bartramiaceae, Bryaceae, Thuidiaceae, Sematophyllaceae, Pterobryaceae, Meteoriaceae, Hookeriaceae, Pottiaceae, Calymperaceae and Fissidentaceae) for Bahia and represent an additional contribution to the knowledge of the bryophyte flora of this state
The indirect costs of depression on the Portuguese population in 2014 and 2019
ABSTRACT - Depression is a highly prevalent and very disabling disease. Different factors may
contribute to its development and, even in mild cases, depression causes a loss of
productivity and generates high indirect costs to society. Literature on the Portuguese
context is scarce and not up to date. This study intended to provide additional and
updated information on the indirect costs of depression due to absenteeism and on
disease prevalence in the years of 2014 and 2019 for the adult population.
The study used data from the population-based National Health Surveys of 2014 and
2019 to study the prevalence, risk factors and association of depression to work
absence. The indirect costs were estimated based on these data and on the average
monthly earnings in Portugal from the Instituto Nacional de Estatística.
The prevalence of depression in the adult Portuguese inhabitants increased from 2014
to 2019 both in the general (13.7 vs 15.1%) and working populations (7.8 vs 9.2%).
Having depression represented an additional work absence of 10.3 to 33.0 days in 2014
and between 15.2 to 41.0 days in 2019. The mean individual excess cost related to
depression varied between 535.12 and 1,716.09 EUR in 2014 and between 852.45 and
2,291.11 EUR in 2019. These values may represent 163-524 million EUR in 2014 and
294-790 million EUR in 2019 when considering the Portuguese workforce. These results
demonstrate the importance of an intervention to improve mental health care to the
Portuguese society and implement cost-effective measures.RESUMO - A depressão é uma doença altamente prevalente e incapacitante. Diferentes fatores
poderão contribuir para o seu desenvolvimento e, mesmo em casos ligeiros, causa
perdas de produtividade e origina altos custos indiretos para a sociedade. A literatura
sobre o contexto português é escassa e não está atualizada. Este estudo pretendeu
fornecer informação adicional e atualizada sobre os custos indiretos da depressão
devida ao absentismo e a sua prevalência nos anos 2014 e 2019 nos adultos.
O estudo usou dados dos Inquéritos Nacionais de Saúde, de base populacional, de 2014
e 2019 para estudar a prevalência, fatores de risco e a associação de depressão à
ausência ao trabalho. Os custos indiretos foram estimados com base nestes dados e no
ganho médio mensal em Portugal de acordo com o Instituto Nacional de Estatística.
A prevalência de depressão nos residentes portugueses adultos aumentou de 2014 para
2019 na população geral (13.7 vs 15.1%) e na empregada (7.8 vs 9.2%). Ter depressão
representou uma ausência ao trabalho adicional de 10.3 a 33.0 dias em 2014 e de 15.2
a 41.0 dias em 2019. O custo adicional médio individual da depressão variou entre
535.12 e 1,716.09 EUR em 2014 e entre 852.45 e 2,291.11 EUR em 2019.
Considerando a força de trabalho portuguesa, estes valores podem representar 163-
524 milhões EUR em 2014 e 294- 790 milhões EUR em 2019. Estes resultados
demonstram a importância de uma intervenção para melhorar os cuidados de saúde
mental à sociedade portuguesa e implementar medidas que sejam custo-efetivas
