Self-efficacy beliefs of university students: an empirical study on the specificity of the construct
2010
This study tested two propositions of the Social Cognitive Theory in an academic setting: a) Self-efficacy is a domain- specific competence belief; b) Domain-specific selfefficacy is related, but distinct from, other self-evaluation constructs. Participants (272 Spanish university students) completed measures of general self-efficacy, academic self-efficacy, statistics self-efficacy and attitudes towards statistics (cognitive and affective components). Principal Components Analyses and Confirmatory Factorial Analyses were performed, among other procedures. Taken as a whole, results support the propositions tested.
Detection of steering direction using EEG recordings based on sample entropy and time-frequency analysis.
2016
Monitoring driver's intentions beforehand is an ambitious aim, which will bring a huge impact on the society by preventing traffic accidents. Hence, in this preliminary study we recorded high resolution electroencephalography (EEG) from 5 subjects while driving a car under real conditions along with an accelerometer which detects the onset of steering. Two sensor-level analyses, sample entropy and time-frequency analysis, have been implemented to observe the dynamics before the onset of steering. Thus, in order to classify the steering direction we applied a machine learning algorithm consisting of: dimensionality reduction and classification using principal-component-analysis (PCA) and sup…
Impaired circadian heart rate variability in Parkinson’s disease: a time-domain analysis in ambulatory setting
2020
Abstract Background Heart rate variability (HRV) decreases in Parkinson’s disease (PD) and it can be considered a marker for cardiovascular dysautonomia. The purpose of this pilot study is to evaluate long-term time-domain analysis of HRV of PD patients and compare the results with those of matched healthy individuals. Methods Idiopathic PD patients without comorbidity impairing HRV, and age-matched healthy individuals were recruited in a pilot study. A long-term time domain analysis of HRV using 24-h ambulatory ECG was performed. Results Overall, 18 PD patients fulfilling inclusion criteria completed the evaluation (mean age was 55.6 ± 8.8, disease duration: 5.0 ± 4.7). Mean SCOPA-AUT scor…
La Ley 41/2002, de 14 de noviembre, básica reguladora de la autonomia del paciente y de los derechos y obligaciones en materia de información y docum…
2003
En el presente trabajo se va a exponer (por su extensión en dos partes) el contenido básico de la reciente Ley sobre autonomía de los pacientes, con referencia expresa a las leyes autonómicas sobre la misma materia. Es de destacar que en todas ellas se consagra como un principio fundamental en la relación médico-paciente el principio de información y requerimiento del consentimiento al paciente para la realización de cualquier intervención sobre el mismo. Asimismo, se establecen los mecanismos de sustituciónde ese consentimiento cuando el paciente no se encuentre en condiciones de darlo por incapacidad o minoría de edad. Por otra parte, se regula mínimamente el documento de voluntades antic…
Level-crossing rate and average duration of fades of non-stationary multipath fading channels
2017
The level-crossing rate (LCR) and average duration of fades (ADF) are important statistical quantities describing the fading behaviour of mobile radio channels. To date, these quantities have only been analysed under the assumption that the mobile radio channel is wide-sense stationary, which is generally not the case in practice. In this paper, we propose a concept for the analysis of the LCR and ADF of non-stationary channels. Rice's standard formula for the derivation of the LCR of wide-sense stationary processes is extended to a more general formula enabling the computation of the instantaneous LCR of non-stationary processes. The application of the new concept results in closed-form ex…

Family Matters : Abusing Family Refresh Tokens to Gain Unauthorised Access to Microsoft Cloud Services Exploratory Study of Azure Active Directory Fa…
2022
Azure Active Directory (Azure AD) is an identity and access management service used by Microsoft 365 and Azure services and thousands of third-party service providers. Azure AD uses OIDC and OAuth protocols for authentication and authorisation, respectively. OAuth authorisation involves four parties: client, resource owner, resource server, and authorisation server. The resource owner can access the resource server using the specific client after the authorisation server has authorised the access. The authorisation is presented using a cryptographically signed Access Token, which includes the identity of the resource owner, client, and resource. During the authorisation, Azure AD assigns Ac…
CAP et BEP : une insertion typée selon la spécialité
1995
International audience; Toutes les études consacrées à l'insertion s'accordent à reconna\ⁱtre que les itinéraires des jeunes sont de plus en plus longs et complexes, où alternent périodes de chômage, d'emplois précaires, de stages .. Le risque de chômage s'avère d'autant plus grand que le niveau de formation est faible, l'écart entre sexes est nettement en défaveur des jeunes filles en ce qui concerne l'accès à l'emploi. La dégradation générale du marché du travail a profondément retenti sur la situation des débutants à leur entrée dans la vie active. Pourtant cette détérioration générale renforce les disparités d'insertion selon le niveau de formation, la spécialité suivie et la région de …
The use of imidazolium group-containing Bronsted acids for masspectrometric determination of biogenic amines in alcoholic beverages
2017
Darbā ir izstrādāta metode sešu biogēno amīnu masspektrometriskai noteikšanai alkoholiskos dzērienos. Metodes pamatā ir kompleksu veidošanās starp biogēniem amīniem un imidazolija grupu saturošu Brensteda skābi, kas nodrošina ātru un selektīvu analīzi bez parauga sagatavošanas. Darba gaitā ir izpētīta vairāku masspektrometra parametru ietekme uz biogēno amīnu kompleksu rašanos, un izvēlētas specifiskās MRM pārejas. Metodes aprobācijai izvēlēti un analizēti astoņi alkoholiskie dzērieni.
Type-IIA secreted phospholipase A2 is an endogenous antibiotic-like protein of the host.
2010
International audience; Type-IIA secreted phospholipase A(2) (sPLA(2)-IIA) has been proposed to play a role in the development of inflammatory diseases. It has been shown to release arachidonic acid, the precursor of proinflammatory eicosanoids, to hydrolyze phospholipids of pulmonary surfactant, and to bind to specific receptors located on cell surface membranes. However, the most established biological role of sPLA(2)-IIA is related to its potent bactericidal property in particular toward Gram-positive bacteria. This enzyme is present in animal and human biological fluids at concentrations sufficient to kill bacteria. Human recombinant sPLA(2)-IIA is able to kill Gram-positive bacteria at…
