I doni di Medea. Tra reciprocità e vendetta
2019
Qual è la funzione dei doni nella storia di Medea, e che cosa ci comunicano? Attraverso di essi Medea sembra in grado di costruire relazioni e, all’opposto, di vendicarsi sui suoi nemici. È sulla base dei doni che interpreta offese e vendetta come inversioni dei meccanismi di reciprocità positiva in cui è calata. Partendo dunque dall’assunto che Medea sia, innanzitutto, una “donatrice al femminile”, il contributo esamina le più rilevanti rappresentazioni della sua storia mitica alla luce della categoria del dono. Pertanto, nella prima parte (“i doni per Giasone”) si presterà particolare attenzione alle “Medee” di Pindaro, Apollonio Rodio, Ovidio e Valerio Flacco, senza tralasciare le …
Deterministic versus probabilistic consequences of trust and trustworthiness: An experimental investigation
2014
Abstract There is overwhelming evidence of reciprocal behavior, driven by intentions. However, the role of consequences is less clear cut. Experimentally manipulating how efficient trust and reciprocity can be in deterministic and uncertain environments allows us to study how payoff consequences of trust and trustworthiness affect reciprocity. According to the results for our modified Investment Game, trustees reward trust more when trust is more efficient but do not adjust rewards when the efficiency of rewarding is varied. Furthermore, higher deterministic benefits result in higher levels of reciprocity for all trust levels, whereas an uncertain environment diminishes reciprocity.
Evaluation of the time required to perform three retreatment techniques with dental microscope and ultrasonic activation for removing filling materia…
2018
Background When endodontic treatment fails, retreatment consists of the complete removal of the root canal filling material for thorough cleaning and reobturation. Various techniques are available for the filling removal procedure, which present varying degrees of efficacy, and take a varying length of time to perform. The aim of this study was to compare the time required to carry out reciprocating, rotary, and manual techniques with dental microscope and ultrasonic activation for removing filling material from root canals. Material and Methods Ninety-nine extracted single-rooted teeth with straight and oval-shaped canals were selected. The samples were instrumented with ProTaper Gold Syst…
Influence of Operator's Experience on Root Canal Shaping Ability with a Rotary Nickel-Titanium Single-File Reciprocating Motion System
2013
The aim of this study was to evaluate the influence of the operator's experience on the shaping of double-curvature simulated root canals with a nickel-titanium single-file reciprocating motion system.Sixty double-curvature root canals simulated in methacrylate blocks were prepared by 10 students without any experience in endodontics and by 10 professionals who had studied endodontics at the postgraduate level. The Reciproc-VDW system's R25 file was used in the root canal preparation. The blocks were photographed before and after the instrumentation, and the time of instrumentation was also evaluated. Changes in root canal dimensions were analyzed in 6 positions.Significant differences (P.0…
Root canal shaping of curved canals by Reciproc Blue system and Pro Taper Gold: A micro-computed tomographic study
2021
Background This study aimed to evaluate the centralization and transportation of ProTaper Gold (PTG) rotary system and Reciproc Blue (RB) reciprocating system in curved canals, by using micro-CT. Material and Methods Twenty extracted mandibular molars were previously scanned by using the SkyScan 1174 microtomograph to select the Vertucci IV anatomic type. The specimens were divided into two groups (n=10) according to the mechanized system used to prepare the root canals. The teeth were scanned by micro-CT to calculate the increase volume, percentage of dentin removed, remaining dentin thickness, structure model index (SMI), degree of transportation and centering ability of root canals. The …
Fundamentos antropológicos en las relaciones interpersonales y de reciprocidad en el pensamiento de Emmanuel Mounier
2013
Uno puede preguntarse si el pensamiento de Emmanuel Mounier es actual o tiene capacidad de influir en el mundo contemporáneo. Sólo basta con echar un vistazo rápido a nuestra realidad actual y aquella que vivió nuestro autor para observar, sobre todo después de los acontecimientos del 11 de septiembre de 2001, las guerras en Irak y Afganistán, las distintas y variadas guerras menores a lo largo del mundo, tras el colapso las bolsas de valores y los mercados en 2008 y 2009, que el mundo nunca había estado tan cerca de una crisis de civilización como aquella crisis de económica del '29 que engendró a la Segunda Guerra Mundial y que parece poner en peligro la propia supervivencia de la cultura…
Perceived Reciprocity and Well-Being at Work in Non-Professional Employees: Fairness or Self-Interest?
2012
This article assesses the links between non-professional employees' perceptions of reciprocity in their relationships with their supervisors and the positive and negative sides of employees' well-being at work: burnout and engagement. Two hypotheses were explored. First, the fairness hypothesis assumes a curvilinear relationship where balanced reciprocity (when the person perceives that there is equilibrium between his/her efforts and the benefits he/she receives) presents the highest level of well-being. Second, the self-interest hypothesis proposes a linear pattern where over-benefitted situations for employees (when the person perceives that he/she is receiving more than he/she deserves)…
Multiplicity of Radial Ground States for the Scalar Curvature Equation Without Reciprocal Symmetry
2022
AbstractWe study existence and multiplicity of positive ground states for the scalar curvature equation $$\begin{aligned} \varDelta u+ K(|x|)\, u^{\frac{n+2}{n-2}}=0, \quad x\in {{\mathbb {R}}}^n\,, \quad n>2, \end{aligned}$$ Δ u + K ( | x | ) u n + 2 n - 2 = 0 , x ∈ R n , n > 2 , when the function $$K:{{\mathbb {R}}}^+\rightarrow {{\mathbb {R}}}^+$$ K : R + → R + is bounded above and below by two positive constants, i.e. $$0<\underline{K} \le K(r) \le \overline{K}$$ 0 < K ̲ ≤ K ( r ) ≤ K ¯ for every $$r > 0$$ r > 0 , it is decreasing in $$(0,{{{\mathcal {R}}}})$$ ( 0 , R ) and increasing in $$({{{\mathcal {R}}}},+\infty )$$ ( R , + ∞ ) for a certain $${{{\mathcal {R}}}}&g…
Myślenie dialogiczne. W polu gry o prawdę etyczną
2019
Przedmiotem analiz artykułu jest pojęcie myślenia dialogicznego. Jest ono różne od pojęcia dialogu–literackiej figury, która służy do przekazywania poglądów filozoficznych. Myślenie dialogiczne, jako merytorycznie nowy sposób uprawiania filozofii, pojawia się dopiero w początkach XX w. Zrodziło się ono jako sprzeciw wobec redukcyjnych metod nauk przyrodniczych i przeniesienia ich w obszar myśli humanistycznej i antropologicznej. W ten sposób powstał nowy nurt filozoficzny – filozofia dialogu. Rozwijał się w duchu uwag krytycznych kierowanych pod adresem dotychczasowej tradycji filozofii zachodniej. W artykule przedstawione zostały konstytutywne cechy myślenia dialogicznego. Najpierw przepro…
Plasmid-mediated QnrS2 determinant from a clinical Aeromonas veronii isolate.
2008
The main objective of this study was to determine the prevalence of the Qnr determinants in clinical and environmental Aeromonas spp. A total of 52 Aeromonas sp. isolates identified by biochemical methods (5), 25 isolated from natural waters (1) and 27 isolated from clinical samples from hospitals in Valencia, Spain, were tested for quinolone resistance by the disk diffusion method (4) (nalidixic acid, 30 μg; oxolinic acid, 2 μg; flumequine, 30 μg; ciprofloxacin, 5 μg; and levofloxacin, 5 μg). Among the studied isolates, 27 showed resistance to nalidixic acid and susceptibility to ciprofloxacin, 24 isolates were susceptible to both nalidixic acid and ciprofloxacin, and only 1, the A. veroni…
