PSICOLOGÍA POSITIVA: ANÁLISIS DESDE SU SURGIMIENTO
2015
More than a decade since the foundation of Positive Psychology by Martin Seligman, this paper aims to analyze this branch of psychology starting at its very beginning, considering its precedents, its topics of interest, its production, its diffusion, its implications for clinical practice, and future research lines. Furthermore, this paper introduces a discussion regarding the future of Positive Psychology: either its dissolution, or its integration with the other fields of psychology.
Полско-българските отношения през 20-те години на XX век – преглед на избрани проблемиi
2020
In the article, the multi-faceted cooperation between Poland and Bulgaria in the 1920s in the political, economic and cultural spheres is presented based on Polish archival materials. After the end of the First World War, Bulgarians wanted more equal relations with Poland, because they wanted Poland to be an advocate of Bulgaria. The motto of Polish Balkan policy was, above all, cooperation with Romania in the event of a war threat from Soviet Russia (later USSR). In this context, political relations with Bulgaria had to become less important, whereas economic cooperation was focused on mutually advantageous trade exchange. The author of the article emphasizes the fact that during the perio…
Incidence and Management of Recurrence in Patients with Crohn's Disease Who Have Undergone Intestinal Resection: The Practicrohn Study.
2017
Background: More than 50% of patients with Crohn's disease require intestinal resection at least once. Postoperative recurrence (POR) is almost uniform if prophylactic treatment is not started early. Endoscopic monitoring is generally advised. We studied the incidence and management of recurrence in patients who had undergone intestinal resection. Methods: Practicrohn was an observational retrospective study performed in 26 Spanish hospitals including patients aged >= 18 years who underwent Crohn's disease-related ileocolonic resection between January 2007 and December 2010. We recorded preventive treatments, the incidence of clinical recurrence in daily practice, and associated risk factor…
Central Region Upgrade for the Jyväskylä K130 Cyclotron
2020
The Jyväskylä K130 cyclotron has been in operation for more than 25 years providing beams from H to Au with energies ranging from 1 to 80 MeV/u for nuclear physics research and applications. At the typical energies around 5 MeV/u used for the nuclear physics program the injection voltage used is about 10 kV. The low voltage limits the beam intensity especially from the 18 GHz ECRIS HIISI. To increase the beam intensities the central region of the K130 cyclotron is being upgraded by increasing the injection voltage by a factor of 2. The new central region with spiral inflectors for harmonics 1-3 has been designed. The new central region shows better transmission in simulations than the origi…
La hubris manageriale quale fonte della irresponsabilità d’impresa: uno studio esplorativo
2014
Obiettivo del paper: L’ondata di scandali etici che ha colpito intensamente il mondo delle imprese a partire dalla fine del XX secolo ha fatto emergere l’esigenza di esplorare i meccanismi istituzionali tesi a evitare nuovi casi di corporate social irresponsibility (CSI). S’intende contribuire a tale dibattito introducendo la trappola della hubris manageriale quale determinante della CSI. Metodologia: Esame qualitativo-longitudinale del caso Parmalat nel periodo in cui è stata sotto la guida del suo fondatore Calisto Tanzi (1961-2003). L’analisi del caso segue i criteri scientifici del campionamento teorico, della triangolazione dei fatti e della periodizzazione della narrazione. Risultati:…
How paradoxical is ‘paradoxical’ outcome? : Different pathways and implications
2021
The present special issue includes single and multiple case studies which report on the phenomenon of ‘paradoxical’ outcomes in psychotherapy, operationalized as discordant outcome assessments within the same case. In an attempt to find ground for my published response, I endeavored to juxtaposition the cases from the different studies, and by doing that gain an overview of the contributions and arguments. As a result of that exercise, I suggest three different types of paradoxical outcome with different pathways and implications. Discussing the concept of ‘illusory mental health’ as a possible explanation for paradoxical outcome, I suggest that self-ratings within a nonclinical range, give…
Cooperación condicional y tercer sector
2000
The following paper analyzes the problem of social cooperation in the provision of a public good from an evolutionary perspective. To this end we depart from behavioral programs as the basic building block for modeling individuals in the social interaction, which is based on a generalized prisoners dilemma. In it, a population of individuals follow a conditional cooperative program, which some authors refer as to morality, and that we will show that is equivalent to the application of the principle of reciprocity. It will be shown that the degree of cooperation, that is the individual contribution toward the provision of the public good, is positive although sub-optimal. Finally, if we comp…
Endogenous firm asymmetry and cooperative R&D in linear duopoly with spillovers
2005
In a linear model ofcost reducing R&D/Cournot competition, firm asymmetry is shown to be sustainable as subgame perfect Nash equilibrium with R&D competition only ifthe productivity of research is sufficiently large relative to the benefits from imitation. In such a case, industry-wide cost reduction and firms asymmetry are increasing and decreasing functions of the spillover rate, respectively. In the absence of spillovers, a symmetric joint lab generates higher consumer surplus and social welfare than a pair ofasymmetric competitors. If spillovers are not too small, asymmetric R&D competition is advantageous toconsumers, but not to firms.
Expectations as Reference Points: Field Evidence from Professional Soccer
2015
We show that professional soccer players and their coaches exhibit reference-dependent behavior during matches. Controlling for the state of the match and for unobserved heterogeneity, we show on a minute-by-minute basis that players breach the rules of the game, measured by the referee’s assignment of cards, significantly more often if their teams are behind the expected match outcome, measured by preplay betting odds of large professional bookmakers. We further show that coaches implement significantly more offensive substitutions if their teams are behind expectations. Both types of behaviors impair the expected ultimate match outcome of the team, which shows that our findings do not si…
L'incidence des LBO sur la politique d'investissement et la gestion opérationnelle des firmes acquises:le cas français
2002
Cet article étudie dans quelle mesure la politique d'investissement ainsi que la gestion opérationnelle des firmes françaises reprises dans le cadre d'un leveraged buy-out (LBO) peuvent expliquer la dégradation de leur surperformance après l'opération. L'étude empirique porte sur 132 LBO réalisés en France de 1989 à 1994. Les résultats obtenus montrent qu'on ne peut expliquer la réduction anormale de la rentabilité économique de ces firmes par un effet mécanique imputable à des surinvestissements, ni par une dérive de la gestion de leurs actifs et passifs d'exploitation. En revanche, l'augmentation des frais de personnels ainsi que des consommations intermédiaires et/ou des réductions de pr…
