O trabalho autónomo na área das ciências naturais: utilização de materiais e a sua organização
Dissertação de mestrado em Ensino na especialidade de educação pré-escolar e ensino do 1º ciclo do Ensino Básico. Instituto Politécnico de Beja, Escola Superior de Educação, 2014.Neste estudo pretende-se, a partir da observação realizada numa sala de jardim-deinfância
e da análise da atuação educativa da educadora, estudar a forma de utilizar e
organizar materiais para promover o trabalho autónomo das crianças, na área das
ciências naturais.
Para tal, realizar-se-á um processo de investigação em que participarão as
crianças e a própria educadora da sala. A partir dos instrumentos de recolha de dados,
neste caso, uma lista de verificação para avaliar o material existente na sala e uma
entrevista à educadora, caracterizar-se-á a situação real.
Depois de encontradas as fragilidades, no sentido de as ultrapassar, constituir-seá
um plano de ação que será desenvolvido nas suas várias dimensões
UGROŽENE VRSTE RIBA U SVIJETU: Squalius malacitanus Doadrio i Carmona 2006 (Cyprinidae)
Squalius malacitanus is an endemic cyprinid fish from the south of the Iberian Peninsula. This species is endangered due to habitat destruction, damming and low water availability.Squalius malacitanus je endemska ciprinidna vrsta ribe s juga Iberijskog poluotoka. Ova vrsta ugrožena je zbog uništavanja staništa, postavljanja brana i slabe dostupnosti vode
UGROŽENE VRSTE RIBA U SVIJETU: Squalius castellanus Doadrio, Perea i Alonso 2007 (Cyprinidae)
Squalius castellanus is an endemic cyprinid fish from the Iberian Peninsula, with a distribution area restricted to the River Tagus (Gallo sub-basin). This species is critically endangered mainly due to pollution and fluctuations of the water regime.Squalius castellanus je endemska ciprinidna vrsta ribe s Iberijskog poluotoka, s distribucijskim područjem ograničenim na rijeku Tagus (podsliv rijeke Gallo). Ova je vrsta kritično ugrožena uglavnom zbog zagađenja i fluktuacija vodnog režima
UGROŽENE VRSTE RIBA U SVIJETU: Cottus hispaniolensis Bacescu-Mester, 1964 (Cottidae)
Cottus hispaniolensis is a critically endangered cottid fish which is endemic from the Pyrenanean Garonne river basin.Cottus hispaniolensis je kritično ugrožena vrsta ribe iz porodice Cottidae, a endemska je u slivu pirenejske rijeke Garonne
UGROŽENE VRSTE RIBA U SVIJETU: Cobitis vettonica Doadrio & Perdices, 1997 (Cobitidae)
Cobitis vettonica is an endemic cobitid fish from the Iberian Peninsula with a distribution area restricted to the River Águeda (Douro river basin) and the Alagón and Eljas rivers (Tagus river basin). This species is endangered due to pollution, habitat destruction by sediment removal and damming, and introduction of exotic species.Cobitis vettonica je endemska vrsta s Iberijskog poluotoka ograničene distribucije na rijeku Águeda (sliv rijeke Douro) te rijeke Alagón i Eljas (sliv rijeke Tagus). Vrsta je ugrožena zbog zagađenja, destrukcije staništa iskorištavanjem sedimenta, gradnjom brana i unošenjem egzotičnih vrsta
Genetic variability of Candida albicans SAP8 propeptide in isolates from different types of infection
The secreted aspartic proteases (Saps) are among the most studied virulence determinants in Candida albicans. These proteins are translated as pre-pro-enzymes consisting of a signal sequence followed by a propeptide and the mature enzyme. The propeptides of secreted proteinases are important for the correct processing, folding/secretion of the mature enzyme. In this study, the DNA sequences of C. albicans Saps were screened and a microsatellite was identified in SAP8 propeptide region. The genetic variability of the repetitive region of Sap8 propeptide was determined in 108 C. albicans independent strains isolated from different types of infection: oral infection (OI), oral commensal (OC), vulvovaginal candidiasis (VVC), and bloodstream infections (BSI). Nine different propeptides for Sap8 processing were identified whose frequencies varied with the type of infection. OC strains presented the highest gene diversity while OI isolated the lowest. The contribution of the Saps to mucosal and systemic infections has been demonstrated and recently Sap8 has been implicated in the cleavage of a signalling glycoprotein that leads to Cek1-MAPK pathway activation. This work is the first to identify a variable microsatellite in the propeptide of a secreted aspartic protease and brings new insights into the variability of Sap8.This research was supported by FEDER funds through the Operational Programme COMPETE and national funds through Fundação para a Ciência e Tecnologia (FCT), in the scope of project PEst-OE/BIA/UI4050/2014.info:eu-repo/semantics/publishedVersio

Neuroticism and attention toward sexual and non‑sexual images during an oddball task: evidence from event‑related potentials
UGROŽENE VRSTE RIBA U SVIJETU: Achondrostoma salmantinum, Doadrio i Elvira, 2007 (Cyprinidae)
Achondrostoma salmantinum is a small, endemic cyprinid fish from the Iberian Peninsula. It occurs in some tributaries of the Douro river basin in the Salamanca province (western Spain) and is currently endangered due to receding water levels resulting from extensive agriculture, construction of dams and weirs and water transfers.Achondrostoma salmantinum je mala endemska ciprinidna riba s Iberijskog poluotoka. Pojavljuje se u nekim pritocima sliva rijeke Douro u pokrajini Salamanci (zapadnoj Španjolskoj) i trenutno je ugrožena zbog opadanja vodostaja koji je rezultat ekstenzivne poljoprivrede, izgradnje brana i pregrada te vodenih transfera
Patterns of Parental Reactions to Their Children’s Negative Emotions: A Cluster Analysis with a Clinical Sample
Parents’ emotion socialization practices are an important source of influence in the development of children’s emotional competencies This study examined parental reactions to child
negative emotions in a clinical sample using a cluster analysis approach and explored the associations
between clusters of parents’ reactions and children’s and parents’ adjustment. The sample comprised
80 parents of Portuguese children (aged 3–13 years) attending a child and adolescent psychiatry unit.
Measures to assess parental reactions to children’s negative emotions, parents’ psychopathological
symptoms, parents’ emotion dysregulation, and children’s adjustment were administered to parents.
Model-based cluster analysis resulted in three clusters: low unsupportive, high supportive, and
inconsistent reactions clusters. These clusters differed significantly in terms of parents’ psychopathological symptoms, emotion dysregulation, and children’s adjustment. A pattern characterized by
high supportive reactions to the child’s emotions was associated with higher levels of children’s
adjustment. On the other hand, an inconsistent reactions pattern was associated with the worst
indicators of children’s adjustment and parental emotion dysregulation. These results suggest the
importance of supporting parents of children with emotional and behavioural problems so that they
can be more responsive to their children’s emotional manifestations.info:eu-repo/semantics/publishedVersio
