Medieval Sources and Present-Day Folklore Materials on Saints in an Electronic Encyclopedia

This paper discusses the variety of the digitized content of an electronic encyclopedia on the veneration of saints according to Bulgarian sources. The emphasis is on medieval Slavonic Church manuscripts and on present-day records of Bulgarian folklore narratives and songs. The combination of these sources provokes discussion of the so-called folklore Christianity and adds new dimensions to the understanding of the role of the cults of saints for culture and of the religiosity of the Bulgarians.

"Raíñas de pedra": a Humanizing Review of Inés de Castro’s Life and Death

The tragic love between Pedro I from Portugal and Inés de Castro became, in its earlier stages, a recurrent theme of the Portuguese, Spanish and European cultural scene. The dead queen came to represent the universal myth of the innocent woman sacrificed due to the Reason of State and she became the personification of the victory of love beyond death. However, despite its strong connection with Galicia, this figure was excluded from Galician literature for many years. This article’s purpose is to review and analyse the main work that introduced the figure of Inés de Castro to the Galician literary scene, Raíñas de Pedra, by Cándido Pazó, emphasising its originality and innovation in relation to the rest of the corpus.

The effect on the performance of listed family and non-family firms

Purpose: The purpose of this paper is to examine whether the ownership of public firms is related to accounting and market performance, comparing family and non-family listed firms. Design/methodology/approach: We use regression analysis, considering a sample of Portuguese family and non-family firms for the period between 1999 and 2010. Findings: Overall, the results show that family firms are older, are more indebted and have higher debt costs than non-family firms. However, they present lower levels of risk. The evidence suggests that family firms outperform non-family firms when we consider a market performance measure. The market performance of family-controlled firms is more sensitive to the crisis periods and age, compared to their counterparts. The empirical findings suggest that under economic adversity, the performance is especially compromised by the firms’ age. Research limitations/implications: A limitation of this study is the small size of the sample, which derives from the small size of the Portuguese stock market, the Euronext Lisbon. Originality/value: This paper offers some insights on the ownership of public firms and firm performance by investigating a small European economy. The study also contributes to the stream of firm performance, considering new independent variables as determinants of firm performance, such as operational risk. Finally, the study examines the interaction between ownership and performance under both steady and adverse economic conditions, giving the opportunity to analyze whether firm performance differs according to market conditions.

Familial amyloid polyneuropathy: TTR sequencing and "in silico" analysis

Familial amyloid polyneuropathy (FAP) or paramiloidosis is an autosomal dominant neurodegenerative disease with onset on adult age that is characterized by mutated protein deposition in the form of amyloid substance. FAP is due to a point alteration in the transthyretin (TTR) gene and until now more than 100 amyloidogenic mutations have been described in TTR gene. FAP shows a wide variation in age-at-onset (AO) (19-82 years, in Portuguese cases) and the V30M mutation often runs through several generation of asymptomatic carriers, before expressing in a proband, but the protective effect disappear in a single generation, with offspring of late-onset cases having early onset. V30M mutation does not explain alone the symptoms and AO variability of the disease observed in the same family. Our aim in this study was to identify genetic factors associated with AO variability and reduced penetrance which can have important clinical implications. To accomplish this we genotyped 230 individuals, using a directautomated sequencing approach in order to identify possible genetic modifiers within the TTR locus. After genotyping, we assessed a putative association of the SNPs found with AO and an intensive in silico analysis was performed in order to understand a possible regulation of gene expression. Although we did not find any significant association between SNPs and AO, we found very interesting and unreported results in the in silico analysis since we observed some alterations in the mechanism of splicing, transcription factors binding and miRNAs binding. All of these mechanisms when altered can lead to dysregulation of gene expression, which can have an impact in AO and phenotypic variability. These putative mechanisms of regulation of gene expression within the TTR gene could be used in the future as potential therapeutical targets, and could improve genetic counselling and follow-up of mutation carriers.

The Political and Social Dynamics of Poverty, Poor Relief and Health Care in Early-Modern Portugal

By the end of the fifteenth century most European countries had witnessed a profound reformation of their poor relief and health care policies. As this book demonstrates, Portugal was among them and actively participated in such reforms. Providing the first English language monograph on this topic, Laurinda Abreu examines the Portuguese experience and places it within the broader European context. She shows that, in line with much that was happening throughout the rest of Europe, Portugal had not only set up a systematic reform of the hospitals but had also developed new formal arrangements for charitable and welfare provision that responded to the changing socioeconomic framework, the nature of poverty and the concerns of political powers. The defining element of the Portuguese experience was the dominant role played by a new lay confraternity, the confraternity of the Misericórdia, created under the auspices of King D. Manuel I in 1498. By the time of the king's death in 1521 there were more than 70 Misericórdias in Portugal and its empire, and by 1640, more than 300. All of them were run according to a unified set of rules and principles with identical social objectives. Based upon a wealth of primary source documentation, this book reveals how the sixteenth-century Portuguese crown succeeded in implementing a national poor relief and health care structure, with the support of the Papacy and local elites, and funded principally through pious donations. This process strengthened the authority of the royal government at a time which coincided with the emergence of the early modern state. In so doing, the book establishes poor relief and public health alongside military, diplomatic and administrative authorities, as the pillars of centralisation of royal power.

Salt content of processed foods available in the Portuguese market

Evidence suggests that current levels of salt consumption across Europe are linked with several chronic diseases. In recent decades, high blood pressure has increased, together with the consumption of processed foods. World Health Organization (WHO) recommends a salt intake of less than 5 g/day for the prevention of cardiovascular disease. The aim of this study was to evaluate the salt content of processed foods available in the Portuguese market and to compare the determined values with the recommended daily intake established by WHO. Categories of processed foods that contribute to a higher intake of salt were identified: pastry, bakery, fast-food, snacks, ready-to-eat meals, nuts, seeds, soups, cereals, sauces, patties, among others. Between 2013 and 2015, 267 processed food samples were acquired in food chains and restaurants from Lisbon region (Portugal) and the salt content was quantified using Charpentier-Volhard method. High amounts of salt were quantified in the analysed processed foods, namely snacks, fast-food, patties, meals and bakery products. If we consider one portion of a curd cheese pie (193 g), the intake of salt can reach 45% of the recommended value. For snacks, regular portion size is 35 g. One portion of a salty snack can contribute with 31% of the salt recommended daily intake. Up to now food industry has developed efforts to decrease the salt content of some food products, namely bread. However, there still exist foods with high salt content and from a nutritional point of view this should be a priority area of intervention. The obtained results are an effective assessment of current salt content in foods which will be important for further reformulation strategies and to monitor progress in the next years.

Hepatitis B and C prevalence in Portugal: disparity between the general population and high-risk groups

Background and aims: The prevalence of anti-HCV and HBsAg in Portugal has been shown to be elevated in high-risk groups, such as intravenous drug-users and incarcerated individuals. However, in the general population, prevalence remains largely unknown. The aims of this study were to estimate the prevalence of anti-HCV and HBsAg in the general Portuguese population and identify associated risk factors. Materials and methods: We carried out a nationwide, population-based cross-sectional study of adults resident in mainland Portugal. Serology for HBsAg, anti-HBc, anti-HBs, and anti-HCV was performed. Anti-HCV-positive individuals were tested for HCV RNA by PCR. Results: Of 1685 participants, 50.6% were men, mean age 50.2±18.3 years. In terms of hepatitis C, the prevalence of anti-HCV was 0.54% [95% confidence interval (CI): 0.2–0.9] and 0.12% (95% CI: 0.0–0.3) were viremic, with peak prevalence among individuals 35–64 years of age (0.8%), men (0.8%), and individuals from Lisbon and Tagus Valley region (1.9%). In terms of hepatitis B, the estimated prevalence of HBsAg was 1.45% (95% CI: 0.9–2.0). A higher prevalence was found in individuals who were 35–64 years old (2.2%), in men (2.5%), and in the Northern region (2.6%). The presence of positive serological markers of hepatitis C virus and hepatitis B virus infection did not correlate with elevated aminotransferases, race, place of birth, and alcohol consumption. Conclusion: These results suggest a low endemicity for both hepatitis B and hepatitis C in the general population, in contrast to a very high prevalence in risk groups, thus suggesting that targeted screening to high-risk groups may be more cost-effective than general population screening.

Job-related strain and sexual health difficulties among heterosexual men from three european countries: The role of culture and emotional support

Introduction. Epidemiological evidence for the association between job-related stress and sexual difficulties in men is largely lacking. Little is known about the factors that may mediate or moderate this relationship. Aim. This study analyzes the association between job-related difficulties and men’s sexual difficulties. Main Outcome Measures. Job-related difficulties were measured by 10 yes/no questions that addressed a range of adverse workplace situations. The experience of sexual difficulties in the past 12 months was assessed by using seven dichotomous indicators developed in the National Study of Sexual Attitudes and Lifestyles (NATSAL) 2000. Method. Analyses were carried out using data from a 2011 online study of Portuguese, Croatian, and Norwegian men (N = 2,112). Multivariate logistic regression and mediation analysis were used to test the hypothesized association. Results. Men with job-related concerns reported lower sexual satisfaction than men without such concerns did (F = 7.53, P < 0.001). Multivariate analysis confirmed the association between job-related and sexual health concerns. The odds of experiencing one or more sexual health difficulties in the past 12 months were about 1.8 times higher among men who reported the highest levels of workplace difficulties than among men who experienced no such difficulties. The odds of reporting sexual health difficulties were significantly reduced by a higher income (adjusted odds ratio [AOR] = 0.87, P < 0.01), emotional intimacy with one’s partner (AOR = 0.93, P < 0.001), having children (AOR = 0.62–0.66, P < 0.01), and country-specific effects (AOR = 1.98–2.22, P < 0.001). In all three countries, the relationship between job-related and sexual health difficulties was mediated by anxiety and depression. Conclusions. The findings suggest that negative mood is the mechanism behind the association between workplace strain and sexual difficulties. Emotional support, such as couple intimacy and fatherhood, can reduce—independently from sociocultural and socioeconomic factors—the risk of sexual health concerns.

Thermal models, lithosphere thickness and heat flow in South Portugal. Some comments about the subject

Reinterpretation of old heat flow data or use of new data and new techniques of detection of the temperature under the surface have conducted to new heat flow density values in some regions of the globe. The problem of ice melting in Greenland and Antarctica caught the public's attention to the importance of knowledge on heat flow values and thermal structure of the globe. In the last years, several models were presented trying to obtain lithosphere and Moho thickness of the Iberia Peninsula. The work we intend to present is related with the SW part of the Iberia Peninsula ( south of the Ossa Morena zone, South Portuguese Zone and Algarve). The results obtained show a decrease in the thickness of the crust and the lithosphere in this region. Density anomalies in the crust are also referred. I intend to make the connection between the results of these models and the heat flow thermal conductivity, heat production and geological data available for the region, trying to explain the results of heat flow density data obtained.

Preposition Stranding in Heritage Speakers of Brazilian Portuguese

Influential bodies of work in language acquisition studies single out heritage bilingualism as a discrete acquisition process within the bilingualism continuum. In regards to the acquisition of WH-/QU- interrogatives containing prepositional phrases (PP), the present study examined whether heritage speakers (HS) of Brazilian Portuguese (BP) produce preposition stranding (P-stranding) constructions in their heritage language, in contrast to monolingual and adult speakers of BP, where prepositions are pied-piped to form the interrogative. Participants were HS of BP born in the USA and in Brazil, monolinguals, and late bilingual adults. The experiment consisted of an elicited production task and a grammaticality judgment task, both carried out in BP and then in English. Results showed that HS born in the USA use P-stranding in QU- interrogatives productively and systematically, in contrast to the other three groups. Moreover, no evidence of protracted acquisition was found in this group. No signs of attrition were detected among bilinguals.
