The Romanian Prezidentialized Consultative Referendum. Eating Apples from a Poisonous Tree? Personal and Teleological Interpretations
2019
Abstract Through this article, we propose an (original) analytical approach on the consultative referendum of May 2019 and a wider critical landscape regarding the consultative referendum institution by enforcing a teleological interpretation. In this sense, we propose three sections. We will start with a short overview on the use of the consultative referendum in the recent years of Romanian democracy. In the second section we will focus on the consultative referendum from 26 May, 2019. In the third section we will ask the Founding Fathers of the Constitution for an “opinion” regarding the possibilities and impossibilities of the consultative referendum.
Intraocular lens centration and stability: efficacy of current technique and technology
2008
Purpose of review The manuscript presents a review of recently published studies analyzing different methodologies to assess centration and stability of intraocular lenses after implantation. Recent findings Considering that there is no current gold standard for centration and stability of intraocular lenses after implantation, we have summarized the different techniques used clinically for intraocular lenses centration and stability estimation. We have described the use of Scheimpflug imaging, the anterior segment optical coherence tomography and photography analysis used for lens position estimation. Techniques used to assess lens rotation are based on image analysis on digital retroillum…
Classification of SD-OCT Volumes for DME Detection: An Anomaly Detection Approach
2016
International audience; Diabetic Macular Edema (DME) is the leading cause of blindness amongst diabetic patients worldwide. It is characterized by accumulation of water molecules in the macula leading to swelling. Early detection of the disease helps prevent further loss of vision. Naturally, automated detection of DME from Optical Coherence Tomography (OCT) volumes plays a key role. To this end, a pipeline for detecting DME diseases in OCT volumes is proposed in this paper. The method is based on anomaly detection using Gaussian Mixture Model (GMM). It starts with pre-processing the B-scans by resizing, flattening, filtering and extracting features from them. Both intensity and Local Binar…
Structural invariance and stability of sense of coherence: A longitudinal analysis of two groups with different employment experiences
2005
This 5-year follow-up study investigated the structure and the factorial invariance of the 13-item sense of coherence (SOC) scale (Antonovsky, 1987a) in two employment groups (unemployment/lay-off experiences vs. continuous full-time employment) and across two measurement times. In addition, the stability of SOC between these two employment groups was compared. The postal questionnaire data was collected twice, in 1992 and in 1997. The participants were Finnish technical designers (N=352) aged between 25 and 40 years in 1992. A total of 51% of the investigated participants had been employed full-time during the 5-year follow-up period and 49% had been unemployed and/or laid off for a total …
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
La biodiversidad es un concepto complejo, convertido en un importante referente curricular. Esta investigación explora si un ejercicio avanzado de las competencias necesarias para hacer significativo el concepto de biodiversidad en diferentes contextos conlleva una mejora significativa de la calidad de los argumentos implicados en la toma de decisiones sobre conservación de la biodiversidad. Para ello se ha aplicado una metodología cualitativa al análisis de doce argumentos formulados por estudiantes de 1.º de Bachillerato, caracterizados por su elevada complejidad estructural, de los cuales se muestra uno a modo de ejemplo. Los resultados revelan que, a pesar del nivel de cohesión estructu…
Sense of coherence and psychological well-being in cardiac patients: Is the association mediated by self-efficacy?
2019
Aim of the studyA large deal of research on cardiac patients concentrates on analyses of mutual relationships between sense of coherence and psychological well-being, sense of coherence and self-efficacy, or psychological well-being and self-efficacy. It has been proven that self-efficacy plays a crucial role as a mediator of the relationships between various psychological constructs.Subject or material and methodsA total number of 176 patients (82 women and 94 men), age 45-82 years (M = 58.56, SD = 8.25) participated in the study. All participants were patients admitted to the cardiology department with coronary heart disease and undergoing medical interventions. All participants were aske…
Experimental approach for testing the uncoupling between cardiovascular variability series
2002
In cardiovascular variability analysis, the significance of the coupling between two series is commonly assessed by defining a zero level on the magnitude-squared coherence (MSC). Although the use of the conventional value of 0.5 does not consider the dependence of MSC estimates on the analysis parameters, a theoretical threshold Tt is available only for the weighted covariance (WC) estimator. In this study, an experimental threshold for zero coherence Te was derived by a statistical test from the sampling distribution of MSC estimated on completely uncoupled time series. MSC was estimated by the WC method (Parzen window, spectral bandwidth B = 0.015, 0.02, 0.025, 0.03 Hz) and by the parame…
Phase Coherence in Conceptual Spaces for Conversational Agents
2010
This chapter attempts to enhance the traditional chatbots with associative/intuitive capabilities. According to these considerations, it tries to create a conversational agent model that takes into consideration, aside from the traditional rule - based dialogue mechanism, also some sort of intuitive reasoning ability. The aim is in attempting to overcome the rigid pattern - matching rules, proposing a "phase coherence" paradigm into a semantic space. With this locution the chapter intend that the vectors representing the elements of the dialogue are coherent with the context. The chapter trust that this intuitive - associative capability can be obtained using the LSA methodology. The repres…
Early Confucian Legal Thought: A Theory of Natural Law?
2015
Confucianism has often been compared to natural law, mainly to its non-volunta- ristic currents. However, the possibility to include Confucianism in the group of natural law theories is problematic. Recently, a few scholars, and notably Peerenboom, have challenged the widely shared thesis that Confucius and early Confucian thinkers should be mentioned in the ranks of natural law philosophers. He contends that early Confucian jurisprudence is more profitably compared to Dworkin’s coherence theory of law than to natural law. The present article discusses three core points: the laws of nature and natural law, the connection between law and morality, and the basic epistemological assumptions pr…
Generalized coherence and connection property of imprecise conditional previsions.
2008
In this paper we consider imprecise conditional prevision assessments on random quantities with finite set of possible values. We use a notion of generalized coherence which is based on the coherence principle of de Finetti. We consider the checking of g-coherence, by extending some previous results obtained for imprecise conditional probability assessments. Then, we study a connection property of interval-valued gcoherent prevision assessments, by extending a result given in a previous paper for precise assessments.
