A Comparative Analysis of Translations of Lucian Blaga’s Poetry into English
2020
Abstract The complexity of Lucian Blaga’s poetry is a matter of common knowledge. Part of this complexity is related to the elements of prosody that Blaga skilfully employs, to say nothing of the philosophical vein which infuses his writings, and which derives, understandably, from his philosophical work. Mention should also be made of the lyrical character of Blaga’s dramatic works, which adds significantly to the effort of translating his writings into English, or any other language for that matter. In what follows, we intend to offer a bird’s eye view of the volumes that have been translated into English and to analyse a selection of poems comparatively, in order to signal challenges and…
RESOLVING AMBIGUITIES IN ORIENTATION, MOTION, AND DEPTH DOMAINS
1992
Three different perceptual systems—orientation, motion, and depth—can recover a global perceptual organization from spatially correlated random multielement patterns. In all three cases the global structure composed of random elements is evaluated by mechanisms performing measurements in the energy domain within appropriately defined local space—time areas. The selective increase in energy of one fraction of the elements may dramatically change the whole perceptual organization of the stimulus. In specially devised patterns one and the same element can belong to two or more separate perceptual organizations, the perceptual salience of one of which can be reinforced by a luminance increment…
A Stochastic Soft Constraints Fuzzy Model for a Portfolio Selection Problem
2006
The financial market behavior is affected by several non-probabilistic factors such as vagueness and ambiguity. In this paper we develop a multistage stochastic soft constraints fuzzy program with recourse in order to capture both uncertainty and imprecision as well as to solve a portfolio management problem. The results we obtained confirm the studies carried out in literature addressed to integrate stochastic and possibilistic programming.
Robust model calibration using determinist and stochastic performance metrics
2016
International audience; The aeronautics industry has benefited from the use of numerical models to supplement or replace the costly design-build-test paradigm. These models are often calibrated using experimental data to obtain optimal fidelity-to-data but compensating effects between calibration parameters can complicate the model selection process due to the non-uniqueness of the solution. One way to reduce this ambiguity is to include a robustness requirement to the selection criteria. In this study, the info-gap decision theory is used to represent the lack of knowledge resulting from compensating effects and a robustness analysis is performed to investigate the impact of uncertainty on…
<p>El análisis de manuales y la identificación de problemas de investigación en Didáctica de las Matemáticas</p>
2011
La ambigüedad del signo radical es un problema con raíces históricas que ha quedado recogido en una tradición de enseñanza reflejada en los manuales escolares. Como problema matemático ha sido resuelto, pero no como problema didáctico, ya que el signo radical presenta sutilezas conceptuales y operatorias cuya omisión en los manuales es a menudo causa de malentendidos y conflictos fuertemente arraigados. Algunos de esos malentendidos son un producto de la enseñanza tradicional reflejada en los manuales que ignora los desarrollos matemáticos actuales. En este artículo se utiliza el análisis textual y el epistemológico para presentar este problema en sus dimensiones matemática y didáctica. Ana…
How and When Do Leaders Influence Employees' Well-Being? Moderated Mediation Models for Job Demands and Resources
2019
Following the call of recent reviews on leadership and well-being, the purpose of this study is to examine how and when two contrasting leadership styles, transformational leadership (TFL) and passive-avoidant leadership (PAL), are related to employees’ anxiety and thereby either promote or inhibit employees’ well-being. Using the prominent job demands-resources (JD-R) model as a theoretical framework, we propose that the relationship between leadership behavior and anxiety is mediated by organizational job demands, namely, role ambiguity (RA), and job resources, namely, team climate for learning (TCL), as well as moderated by autonomy as important job characteristic. A sample of 501 knowle…
The influence of gender role on negotiation development and outcome
2007
PurposeThe main aim of this paper is to analyze the effect of gender differences on negotiation behaviour choice and, consequently, on its outcome. The analysis undertaken is first defined by distinguishing between sex and gender role. It gender role and not biological sex the factor that can have a direct impact on behaviour. With a contextual perspective, we have chosen the negotiation processes of strategic alliances as our contextual framework of analysis.Design/methodology/approachThe paper adopts a qualitative methodology, particularly case study analysis.FindingsA higher degree of complexity increases the perception of ambiguity, which then leads to the influence of gender in the neg…
How to make head or tail of ‘bridging’ and ‘bonding’?: addressing the methodological ambiguity1
2008
A distinction has recently been proposed between bridging (or encompassing) and bonding (or inward-looking) social networks. However, existing theoretical contributions remain vague as to the fundamental meaning of both concepts. As a consequence, two distinct interpretations have developed alongside each other. In the present paper, we employ data on voluntary association membership in Flanders to empirically illustrate that both approaches can lead to substantially different outcomes and therefore appear to tap into different dimensions of bridging versus bonding. These findings underline the problematic nature of the current conceptual ambiguity. We conclude that should the bridging/bond…
User participation in knowledge update of expert systems
1997
Abstract Applying the Elaboration Likelihood Model (ELM) of persuasion we conducted an experiment to examine the effect of participation of users in the design process on their acceptance of system recommendations and revision of their original decisions. Results of our study indicate that two different types of information processing occur when subjects are reviewing the expert system recommendations. 1. (i) For users who have a high perceived level of participation in updating the knowledge of the ES, ambiguity of the decision setting is the primary determinant affecting acceptance of the recommendation from the ES. 2. (ii) For users who have a low perceived level of participation in upda…
Per una rilettura kantiana del principio di causalità
2018
There is no contradiction between Kant’s statement that the proposition, “every alteration has its cause,” is of no interest to the Critique of Pure Reason because of its dependence on empirical contents (KrV, B 3) and his use of the same proposition as an example of pure a priori knowledge (KrV, B 5). There is only the arduousness and sometimes also the ambiguity of a passage in which Kant attempts to establish a new basis for the validity of the principle of causality.
