Increased intestinal carbonate precipitate abundance in the sea bream (Sparus aurata L.) in response to ocean acidification
Marine fish contribute to the carbon cycle by producing mineralized intestinal precipitates generated as by-products of their osmoregulation. Here we aimed at characterizing the control of epithelial bicarbonate secretion and intestinal precipitate presence in the gilthead sea bream in response to predicted near future increases of environmental CO2. Our results demonstrate that hypercapnia (950 and 1800 μatm CO2) elicits higher intestine epithelial HCO3- secretion ex vivo and a subsequent parallel increase of intestinal precipitate presence in vivo when compared to present values (440 μatm CO2). Intestinal gene expression analysis in response to environmental hypercapnia revealed the up-regulation of transporters involved in the intestinal bicarbonate secretion cascade such as the basolateral sodium bicarbonate co-transporter slc4a4, and the apical anion transporters slc26a3 and slc26a6 of sea bream. In addition, other genes involved in intestinal ion uptake linked to water absorption such as the apical nkcc2 and aquaporin 1b expression, indicating that hypercapnia influences different levels of intestinal physiology. Taken together the current results are consistent with an intestinal physiological response leading to higher bicarbonate secretion in the intestine of the sea bream paralleled by increased luminal carbonate precipitate abundance and the main related transporters in response to ocean acidification.Agência financiadora

Modelos multidimensionais de avaliação de desempenho para o sector público: o caso dos serviços policiais
A introdução das reformas da Nova Gestão Pública (NGP), nos últimos anos, surgem no sentido de introduzir maior eficiência e eficácia no desempenho das organizações públicas, através de uma nova filosofia de gestão, assente, entre outros aspectos, na avaliação do desempenho baseada em outputs e outros.
O desenvolvimento de adequados sistemas de avaliação de desempenho para o sector público tem suscitado o interesse da comunidade académica. O foco é colocado na medida dos outputs (produtos e serviços) e dos outcomes (impactos) e não na medida dos inputs (dotações orçamentais), como acontece tradicionalmente. Este artigo constitui uma revisão da literatura sobre os tipos de modelos de avaliação de desempenho utilizados nas organizações públicas, a utilidade da medida de desempenho para a tomada de decisão e a análise de alguns casos de estudo, especialmente nas forças policiais, sobre a implementação de modelos multidimensionais como o Balanced Scorecard (BSC)
Use of performance measurement in the public sector: the case of the police service
Many public organisations have been under great pressure in recent years to increase the efficiency and transparency of outputs, to rationalise the use of public resources, and to increase the quality of service delivery. In this context, public organisations were encouraged to introduce the New Public Management reforms with the goal of improving the efficiency and effectiveness of the performance organisation through a new public management model. This new public management model is based on measurement by outputs and outcomes, a clear definition of responsibilities, the transparency and accountability of governmental activities, and on a greater value for citizens.
What type of performance measurement systems are used in police services? Are they multidimensional models with an integration of financial and non financial measures? Based on the literature review, we see that multidimensional models, like the Balanced Scorecard, are important in many public organisations, like municipalities, universities, and hospitals. Police services are characterised by complex and diverse objectives and stakeholders. Therefore, performance measurement of these public services calls for a specific analysis. Based on a nationwide survey of all police chiefs of the Portuguese police force, we find that employee performance measurement is the main form of measurement. Also, we propose a strategic map for the Portuguese police service
Performance measurement of the portuguese police force using the balanced scorecard
As a result of reforms brought about by the New Public Management (NPM) movement, public organizations have felt the need to develop adequate information systems to improve the policy process decision-making and to introduce resource allocation based on outputs and outcomes. The objective is to increase efficiency, effectiveness, and the quality of the public service with improved management costs.
What is the role of the BSC in the performance measurement of the Portuguese Police System? And to extent are police agents willing to comply with BSC requirements? The first study of its kind in Portugal, this paper proposes to analyze the BSC´s place in the police management and police predisposition to apply the BSC as a performance measurement system in the Portuguese Police. Using a unique data set assembled by way of a nationwide survey sent to all the police chiefs of the four branches of the Portuguese police, we estimate an ordered logit regression model. We find that prior knowledge of the BSC, as well as the impact of the NPM issues, are important determinants of the predisposition to apply the BSC.Center for Research in Public Policy and Administration (NEAPP).Fundação para a Ciência e a Tecnologia (FCT)
Genetic characterization of some neoponera (Hymenoptera: Formicidae) populations within the foetida species complex
The foetida species complex comprises 13 Neotropical species in the ant genus Neoponera Emery (1901). Neoponera villosa Fabricius (1804) , Neoponera inversa Smith (1858), Neoponera bactronica Fernandes, Oliveira & Delabie (2013), and Neoponera curvinodis (Forel, 1899) have had an ambiguous taxonomic status for more than two decades. In southern Bahia, Brazil, these four species are frequently found in sympatry. Here we used Bayesian Inference and maximum likelihood analyses of COI and 16S mtDNA sequence data and conventional cytogenetic data together with observations on morphology to characterize sympatric populations of N. villosa, N. inversa,
N. bactronica, and N. curvinodis. Our results showed marked differences in the karyotype of these ants. Both N. curvinodis and N. inversa have chromosome number of 2n = 30. Their chromosome composition, however, is distinct, which indicates that N. curvinodis is more closely related to N. bactronica. These four species clustered into three distinct groups. The close relationship between N. bactronica and N. curvinodis deserves further investigation since it has not been fully resolved here. Our results confirm that N. inversa, N. villosa, N. bactronica + N. curvinodis indeed represent four distinct taxa within the foetida species complex
RiskBenefit4EU project – a strategy for risk-benefit assessment of foods in Portugal
O balanço entre os riscos e benefícios para a saúde resultante do consumo
de alimentos é um importante contributo para apoiar a definição de
políticas de saúde e a promoção da literacia dos consumidores. No âmbito
do projeto RiskBenefit4EU, financiado pela European Food Safety Authority
e coordenado pelo Departamento de Alimentação e Nutrição do Instituto
Nacional de Saúde Doutor Ricardo Jorge, o presente trabalho pretende
descrever a estratégia implementada para a capacitação das equipas portuguesas
em avaliação de risco-benefício de alimentos (RBA). Concretizada
pelos parceiros do Institut National de la Recherche Agronomique e da
Technical University of Denmark, a capacitação consiste em três atividades
principais: 1) Formação teórica, focando os conceitos-chave para a
avaliação de RBA; 2) Formação prática, aplicando os conceitos adquiridos
e as metodologias transmitidas a um estudo de caso; e 3) Missões científicas,
de curta duração, para formação avançada em domínios específicos
da avaliação de RBA. No que diz respeito à formação prática, e com o objetivo
de consolidar os conhecimentos adquiridos em avaliação de RBA,
está previsto o desenvolvimento de um estudo de caso português sobre
alimentos à base de cereais habitualmente consumidos por crianças. A
estratégia de capacitação seguida neste projeto servirá de modelo para
outras equipas e países, contribuindo para a disseminação de uma cultura
de avaliação de RBA nas vertentes toxicológica, microbiológica e nutricional
a nível internacional.The balance of risks and health benefits from food consumption constitutes
a crucial topic to consumer literacy and health policy-makers. Through the
RiskBenefit4EU project, funded by the European Food Safety Authority,
and coordinated by the Food and Nutrition Department of Portuguese
National Institute of Health Dr. Ricardo Jorge, the present work intends to
identify the applied strategy to capacitate the Portuguese teams for the development
and implementation of risk-benefit assessment (RBA) in food.
The training of the Portuguese team is being accomplished by the French
National Institute for Agricultural Research and the Technical University
of Denmark members, through three main capacity building activities: 1)
Theoretical training, focusing on the key concepts for RBA; 2) Practical
training, applying the concepts acquired and the methodologies transmitted
to a concrete case study; and 3) Short-term scientific missions for advanced
training in specific areas of RBA. In order to complete the training
of the Portuguese teams and consolidate the knowledge acquired in RBA,
a Portuguese case study on cereal-based foods usually consumed by children
is planned. The training strategy followed in this project will contribute
as a model of capacity building for disseminating a culture of risk-benefit
assessment in the toxicological, microbiological and nutritional aspects at
the international level.Trabalho desenvolvido no âmbito do projeto “RiskBenefit4EU – Partnering

Emotional ratings and skin conductance response to visual, auditory and haptic stimuli
The human emotional reactions to stimuli delivered by different sensory modalities is a topic of interest for many disciplines, from Human-Computer-Interaction to cognitive sciences. Different databases of stimuli eliciting emotional reaction are available, tested on a high number of participants. Interestingly, stimuli within one database are always of the same type. In other words, to date, no data was obtained and compared from distinct types of emotion-eliciting stimuli from the same participant. This makes it difficult to use different databases within the same experiment, limiting the complexity of experiments investigating emotional reactions. Moreover, whereas the stimuli and the participants’ rating to the stimuli are available, physiological reactions of participants to the emotional stimuli are often recorded but not shared. Here, we test stimuli delivered either through a visual, auditory, or haptic modality in a within participant experimental design. We provide the results of our study in the form of a MATLAB structure including basic demographics on the participants, the participant’s self-assessment of his/her emotional state, and his/her physiological reactions (i.e., skin conductance)
