Segurança privada em França
ResPublica : Revista Lusófona de Ciência Política, Segurança e Relações InternacionaisO conceito de segurança, em abstrato, está geralmente relacionado
com perigo ou ameaça e com o sentimento de medo. O termo deriva
do latim securitas, referindo-se à qualidade daquilo que é seguro, ou
seja, àquilo que está ao abrigo de quaisquer perigos, danos ou riscos.
De acordo com o art.º L111-1 do Código da Segurança Interna, «[a]
segurança é um direito fundamental e uma das condições do exercício
das liberdades individuais e coletivas. O Estado tem o dever de garantir
a segurança, zelando, em todo o território da República, pela defesa
das instituições e dos interesses nacionais, pelo respeito das leis, pela
manutenção da paz e da ordem pública, pela proteção das pessoas e
dos bens. Ele associa à política de segurança, no quadro de dispositivos
locais cuja estrutura é definida por via regulamentar, as coletividades
territoriais e os estabelecimentos públicos de cooperação intercomunal,
bem como os representantes das profissões, dos serviços e das associações
confrontados com manifestações de delinquência ou trabalhando
nos domínios da prevenção, da mediação, da luta contra a exclusão
ou da ajuda às vítimas» (França, 2017)
The influence of economic complexity processes and renewable energy on CO2 emissions of BRICS. What about industry 4.0?
This study analyses the relationship between carbon dioxide emissions per capita, the economic complexity index, renewable energy, and inward foreign direct investment using panel data for the BRICS countries from 1995 to 2020. Empirical results confirm that the environmental Kuznets curve is fulfilled, with a positive but decreasing contribution of economic development on environmental deterioration, to the point that neutrality on CO2 emissions can be achieved in the long term. In addition, the results confirm, in this case, the Pollution Haven Hypothesis, that is, the set of BRICS economies chooses to apply regulations that do not respect the environment. The results of other econometric studies support this study, pointing to long-run cointegration. The unit root tests and the variance inflation test also point to stationarity at the first difference and a lack of multicollinearity, respectively.
Finally, given the scarcity of empirical studies, this study adopts an incipient methodology to approximate the impact of the technologies associated with Industry 4.0 on carbon emissions, obtaining evidence that their effect on environmental deterioration is very moderate. In addition, the results suggest that, in the long term, these technologies can contribute to achieving the neutrality of polluting emissions.info:eu-repo/semantics/publishedVersio

Testing differences of marine non-indigenous species diversity across Macaronesia using a standardised approach
12 pages, 7 figures, 4 tables.-- Under a Creative Commons licenseThe introduction of non-indigenous species (NIS) induces severe impacts on marine biodiversity and ecosystems. Macaronesia is an ecologically relevant region where several NIS were detected recently. For the first time, a standard experimental approach was designed to examine biofouling assemblages and investigate NIS across the region. In this context, sessile biofouling assemblages were examined in four recreational marinas in all the Macaronesian archipelagos from 2018 to 2020: the Azores, Madeira, Canary Islands, and Cabo Verde. We hypothesised that NIS numbers, abundance, and recruitment differed in each location due to abiotic and biotic features. From the Azores (higher latitudes) to Cabo Verde (lower latitudes), NIS recruitment and percentage cover decreased following a partial latitude gradient. The present study unveiled 25 NIS, with new records for the Azores (two cryptogenic species), Canary Islands (one NIS and two cryptogenic species), and Cabo Verde (three NIS and three cryptogenic species). The present research represents a pioneer and relevant step in advancing our current understanding of marine biological invasions in Macaronesia, employing a standard and low-cost approachNC is funded by a doctoral grant (SFRH/BD/146881/2019) awarded by Fundação para a Ciência e a Tecnologia (FCT).

Diversity and patterns of marine non-native species in the archipelagos of Macaronesia
Tiago Marques and Carolina Marques thank partial support by CEAUL (funded by FCT through the project UIDB/00006/2020).Aims The present study is the first attempt to grasp the scale and richness of marine biological invasions in Macaronesia. We pioneered a comprehensive non-native species (NNS), inventory in the region to determine their diversity patterns and native distribution origins. NNS were defined here as the result of both introductions and range expansions. We also used statistical modelling to examine relationships among NNS richness, anthropogenic activities, demographic and geographical variables across Macaronesia. Location Macaronesia. Methods A comprehensive literature search was conducted for marine NNS records in Macaronesia, registering the first record's location and year from 1884 to 2020. We used univariate and multivariate analyses to evaluate differences and similarities in community composition. By applying a Generalized Linear Model (GLM), we tested hypotheses regarding NNS richness as a function of anthropogenic activities, demographic and geographical variables. Results A total of 144 marine non-native species (NNS) were recorded for the whole of Macaronesia. The highest NNS richness was registered in the Canary Islands (76 NNS), followed by the Azores (66 NNS), Madeira (59 NNS) and finally Cabo Verde (18 NNS). Some differences amongst archipelagos were observed, such as the high number of non-native macroalgae in the Azores, fishes in the Canary Islands and tunicates in Cabo Verde. Overall, macroalgae, tunicates and bryozoans were the predominant taxonomic groups in the Macaronesian archipelagos. Madeira and Canary Islands were the archipelagos with more similarity in marine NNS, and Cabo Verde the most divergent. Finally, GLM suggested that non-native richness patterns across Macaronesia were dependent on the considered archipelago and strongly affected by (1) minimum distance to the mainland, (2) the total number of ports and marinas and (3) total marinas area (km2). Conclusions The model results and NNS listing in the present study will likely raise the awareness and response regarding marine NNS in the whole Macaronesia region, serving as a baseline for future research as well as implementing and enforcing regulations related to the introduction of marine NNS in oceanic islands.Publisher PDFPeer reviewe
Marine algal flora of Santa Maria Island, Azores
Este artículo contiene 41 páginas, 4 tablas, 15 figuras.Background
The algal flora of the Island of Santa Maria (eastern group of the Azores archipelago) has
attracted interest of researchers on past occasions (Drouët 1866, Agardh 1870, Trelease
1897, Schmidt 1931, Ardré et al. 1974, Fralick and Hehre 1990, Neto et al. 1991, Morton

al. 2017, Parente et al. 2018). Nevertheless, the Island macroalgal flora is not well-known
as published information reflects limited collections obtained in short-term visits by
scientists. To overcome this, a thorough investigation, encompassing collections and
presence data recording, was undertaken at both the littoral and sublittoral levels down to a
depth of approximately 40 m, covering an area of approximately 64 km . The resultant
taxonomic records are listed in the present paper which also provides information on
species ecology and occurrence around the Island, improving, thereby, the knowledge of
the Azorean macroalgal flora at both local and regional scales.
New information
A total of 2329 specimens (including some taxa identified only to genus level) belonging to
261 taxa of macroalgae are registered, comprising 152 Rhodophyta, 43 Chlorophyta and
66 Ochrophyta (Phaeophyceae). Of these, 174 were identified to species level (102
Rhodophyta, 29 Chlorophyta and 43 Ochrophyta), encompassing 52 new records for the
Island (30 Rhodophyta, 9 Chlorophyta and 13 Ochrophyta), 2 Macaronesian endemics

Marine algal flora of São Miguel Island, Azores
Este artículo contiene 52 páginas, 4 tablas, 15 figuras.Background
The macroalgal flora of the Island of São Miguel (eastern group of the Azores Archipelago)
has attracted the interest of many researchers in the past, the first publications going back
to the nineteenth century. Initial studies were mainly taxonomic, resulting in the publication
of a checklist of the Azorean benthic marine algae. Later, the establishment of the
University of the Azores on the Island permitted the logistic conditions to develop both
temporal studies and long-term research and this resulted in a significant increase on
research directed at the benthic marine algae and littoral communities of the Island and
consequent publications.
Prior to the present paper, the known macroalgal flora of São Miguel Island comprised
around 260 species. Despite this richness, a significant amount of the research was never
made public, notably Masters and PhD theses encompassing information regarding
presence data recorded at littoral and sublittoral levels down to a depth of approximately
40 m around the Island and the many collections made, which resulted in vouchers
deposited in the AZB Herbarium Ruy Telles Palhinha and the LSM- Molecular Systematics
Laboratory at the Faculty of Sciences and Technology of the University of the Azores.
The present publication lists the macroalgal taxonomic records, together with information
on their ecology and occurrence around São Miguel Island, improving the knowledge of the
Azorean macroalgal flora at local and regional scales.
New information
A total of 12,781 specimens (including some identified only to genus) belonging to 431 taxa
of macroalgae are registered, comprising 284 Rhodophyta, 59 Chlorophyta and 88
Ochrophyta (Phaeophyceae). Of these, 323 were identified to species level (212
Rhodophyta, 48 Chlorophyta and 63 Ochrophyta), of which 61 are new records for the
Island (42 Rhodophyta, 9 Chlorophyta and 10 Ochrophyta), one an Azorean endemic
(Predaea feldmannii subsp. azorica Gabriel), five are Macaronesian endemisms (the red

Uric acid and cardiovascular disease
O interesse no ácido úrico como um potencial
factor de risco de Doença Cardiovascular é
abordado em inúmeros artigos de revisão. Parece
não haver dúvidas que o ácido úrico é um
factor de risco cardiovascular, ideia essa que
persiste desde há 50 anos. Contudo, a questão
central não é a sua associação com Doença
Cardiovascular, mas se desempenha um papel
causal no desenvolvimento de Doença Cardiovascular.
Tem sido difícil identifi car o papel específi co
da hiperuricémia devido à sua associação
com outros factores de risco cardiovascular,
já estabelecidos, como Hipertensão, Diabetes
Mellitus, Dislipidémia e Obesidade.
Um melhor conhecimento dos mecanismos patogénicos
da hiperuricémia poderão esclarecer
a importância da elevação dos valores séricos
de ácido úrico.The interest in serum uric acid as a potential
Cardiovascular Disease risk factor has balloned
in the last several years with numerous
review articles. There seems little doubt that
serum uric acid is a risk factor for Cardiovascular
Disease, a perception that has persisted for nearly 50 years. However, the central issue
is not whether uric acid is associated with
Cardiovascular Disease, but whether uric acid
plays a causal role in the development of Cardiovascular
Disease.
It has been diffi cult to identify the specifi c
role of elevated serum uric acid because of its
association with established cardiovascular
risk factors such as Hypertension, Diabetes
Mellitus, Hyperlipidaemia and Obesity.
Increased understanding of the mechanisms
underlying these associations may allow a clearer
interpretation of the importance of elevated
serum uric acid concentration
Liver biopsy – evolution in recent cases
Os A.A. estudaram os resultados das biopsias
hepáticas efectuadas no seu Serviço, com o
objectivo de avaliar a evolução da prática relacionada
com a sua realização. Identificaram
as biopsias hepáticas realizadas nos Serviços
de Medicina II, desde 1989 a 2001, na base de
dados do Hospital, através da pesquisa no procedimento
50.11 (CID-9). Obtiveram assim um
total de 610 biopsias no período considerado.
Avaliaram com mais pormenor duas populações,
uma constituída pelos episódios de 1991/
1992 (n=66) – grupo A, confrontando-a com a
de 2000/2001 (n=106) - grupo B. Após o levantamento
dos processos clínicos, consideraram
para estudo 48 doentes no grupo A (72,7 %) e
85 no grupo B (80,2 %), sendo os restantes excluídos
por insuficiência de dados. Nestes grupos
foram avaliados vários parâmetros clínicos
e laboratoriais, sendo efectuadas comparações
entre os grupos.
Dos resultados, os A.A. destacam e comentam
o aumento significativo de biopsias programadas
em relação às executadas em doentes já
internados, no grupo mais recente, e um maior
número total e percentual de casos em que se
optou pela alta no dia da execução do exame.
O advento da radiologia de intervenção também
se fez sentir neste trabalho, pela realização de
biopsias guiadas por tomografia axial computorizada
(TAC) em 12 % dos casos no segundo grupo, técnica inexistente no primeiro. Nas indicações,
houve diminuição do peso da avaliação
para diagnóstico/estadiamento de doença
hepática alcoólica, enquanto se verificou aumento
das biopsias para avaliação de alterações
isoladas dos enzimas hepáticos, de massas
hepáticas e no contexto do pré e pós-transplante
hepático. Como diagnósticos estabelecidos
com a ajuda desta técnica, destacamos a
prevalência da esteato-hepatite não alcoólica
no grupo mais recente.The A.A. analysed the results of liver biopsies
performed in their Services, with the purpose
of evaluating the evolution of the practice related
to the performance of the diagnostic procedure.
The liver biopsies performed in the Medicina
2 Services, from 1989 to 2001, were analysed.
The procedure was identified in the Hospital
data base using the code 50.11 (CID-9).
There were 610 liver biopsies registered during
the study period. Two populations were evaluated
in greater detail. One comprising the cases
from 1991/1992 (n=66) – group A -, comparing
it with the second group from 2000/2001
(n=106) – group B. Several clinical and laboratorial
parameters were analyzed in 48 patients
in group A (72, 7 %) and 85 in group B (80, 2 %).
From the results obtained, the authors point
out and comment on the significant rise in programmed
liver biopsies compared to those performed
in inpatients, in the most recent group(B)
and a larger number of cases that were discharged
the same day of the procedure. The advent
of interventional radiology was also noted in this
paper; the performance of CAT scan guided liver
biopsies in 12 % of the episodes in group B,
as compared to none in group A. Where indications
were respected, there were less procedures
for diagnosis / staging of alcoholic liver disease
and more to evaluate isolated altered liver
enzymes, liver masses and control of pre and
post hepatic transplant. From the diagnosis established
with the aid of this technique, the authors
highlight the prevalence of non alcoholic
steatohepatitis in the most recent group
