The Economic Dynamics in Amoroso's Contribution

This paper aims to highlight the main features of Amoroso's reflections on macroeconomic dynamics to which he dedicated a large part of his scientific activity. He developed an original theory of business cycle and he formulated a dynamic generalisation of the Paretian theory of general economic equilibrium which can be considered the main achievement of dynamic macroeconomics due to its ability to extend the analysis of optimising behaviour to an intertemporal context of resource allocation. The influence of Amoroso was modest despite its undoubted analytical capacity, probably because it was too faithful to a Paretian vision of economic relations and at epistemological level too closely connected to the models of nineteenth century physics which he tried to economic reasoningbusiness cycles, growth, dynamic theory

Simultaneous application of conventional and experimental silanes on the adhesive strength and marginal infiltration in radicular canal with fiberglass post

Orientador: Rafael Leonardo Xediek ConsaniDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Odontologia de PiracicabaResumo: O objetivo neste estudo in vitro foi avaliar o efeito da aplicação simultânea de silanos convencional e experimental na resistência adesiva e micro infiltração marginal em raízes de dentes humanos restauradas com pinos de fibra de vidro (PFV) e submetidas às ciclagens térmica e mecânica. Dois oligômeros foram sintetizados em solução com quantidades catalíticas de trietilamina. O tiol-pentaeritritol tetra-3-mercaptopropionato multifuncional (PETMP) foi combinado com isocianatos di-funcionais - 1,6-hexanodioldiissocyante (HDDI) (alifático) ou 1,3-bis (1-isocianato-1- metiletil) benzeno (BDI) (aromático). Sessenta pré-molares unirradiculares foram seccionados 2 mm acima da junção cemento-esmalte, receberam tratamento endodôntico convencional e obturação com cones de guta-percha. As raízes receberam preparo padronizado em 10 mm de profundidade com brocas de diâmetro 1,4 mm e separadas aleatoriamente em seis grupos (n=10): silanos convencionais (RelyX CP ou Angelus) e experimentais (PETMP-HDDI ou PETMP-BDI). Nos condutos foi aplicado adesivo e nos pinos silanos convencionais conforme recomendado pelos fabricantes, seguido pela aplicação de silanos experimentais. Após cimentação, as raízes receberam núcleos de preenchimento em resina composta, coroas de resina indireta e foram submetidas a 1,2 x 106 ciclos mecânicos, seguidos por 500 ciclos térmicos (5 e 55ºC). Duas fatias com 1 mm de espessura foram obtidas de cada terço radicular (cervical, médio e apical). Uma fatia de cada terço foi submetida ao teste de cisalhamento (push-out) e o padrão de fratura analisado (%) e outra fatia submetida à análise de infiltração marginal por corante (imersão em azul de metileno a 2% por sete dias) e a penetração classificada em escores (%). Fatias representativas de cada grupo foram analisadas em MEV quanto a formação de fendas marginais. Os resultados foram analisados com ANOVA dois-fatores (silano e terço), seguido pelo teste de Tukey (push-out) e teste de Kruskal-wallis (micro infiltração marginal) com nível de significância de ?=0,05. A aplicação simultânea de silanos convencional e experimental aumentou a resistência da união adesiva de PFV (p<0,001), com valores similares entre terços radiculares (p=0,199), reduziu as falhas adesivas dentina-cimento e aumentou as coesivas em dentina. Não houve diferença significante nos escores de micro infiltração por corante entre os grupos (p=0,176). Todos os grupos apresentaram micro infiltração similar ou superior a 2/3 da espessura da fatia. Em conclusão, a aplicação simultânea de silanos convencionais e experimentais proporcionou maior resistência adesiva, reduziu as falhas adesivas dentina-cimento e os níveis de micro infiltração marginal foram similares em canais radiculares tratados com PFVAbstract: The aim of this in vitro study was to evaluate the effect of simultaneous application of conventional and experimental silanes on adhesive resistance and marginal micro-infiltration in human tooth roots restored with fiberglass posts (FGP) and subjected to thermal and mechanical cycling. Two oligomers were synthesized in solution with catalytic amounts of triethylamine. Multi-functional thiol - pentaerythritol tetra-3-mercaptopropionate (PETMP) was combined with di-functional isocyanates - 1,6-hexanedioldiissocyante (HDDI) (aliphatic) or 1,3-bis (1-isocyanato-1- methylethyl) benzene (BDI) (aromatic). Sixty uniradicular premolars were sectioned 2 mm above the cemento-enamel junction, received conventional endodontic treatment and filled with gutta-percha cones. The roots received standardized preparation in 10 mm of depth with drills of diameter 1.4 mm and were randomly separated in six groups (n = 10) according to the variables: conventional silanes (RelyX CP or Angelus) and experimental silanes (PETMP-HDDI or PETMP-BDI). In the root canal, it was applied a three-step adhesive and the post silanized according to the manufacturer's recommendations, followed by the application of experimental silanes. After cementation, the roots received filling cores in composite resin, crowns of indirect resin and were submitted to 1.2 x 106 mechanical cycles, followed by 500 thermal cycles (5 and 55ºC). Two 1-mm thick slices were obtained from each root third (cervical, middle and apical). One slice of each third was submitted to the shear bond test (push-out) and the fracture pattern was analyzed (%), and other subjected to analysis of marginal infiltration by dye (immersion in 2% methylene blue for seven days) and the penetration classified into scores (%). The remaining slices of each group were analyzed in SEM for the gaps formation. The results were analyzed with two-way ANOVA (silane and third), followed by the Tukey's test (push-out) and the Kruskal-wallis' test (micro marginal infiltration) with a significance level of ?=0.05. The simultaneous application of conventional and experimental silanes on FGPs increased the bond strength (p<0.001) with similar values between root thirds (p=0.199), reduced dentin-cement adhesive failures and increased the dentin cohesive failure. There was no significant difference in the micro infiltration scores by dye between the groups (p=0.176). All groups showed micro infiltration similar to or greater than 2/3 of the slice thickness. In conclusion, the simultaneous application of conventional and experimental silanes provided greater adhesive strength, reduced the dentin-cement adhesive failures and the levels of marginal micro infiltration were similar in root canal treated with FGPsMestradoProtese DentalMestre em Clínica OdontológicaCAPE

Investigating the Links Between Performers' Self-Compassion, Mental Toughness and Their Social Environment: A Semi-Systematic Review

Being mentally tough while evaluating oneself in a compassionate way is still a difficult path for performers. Self-compassion, characterized by the ability to be kind to oneself, to see one’s experiences as part of the larger human experience and have a balanced awareness to one’s emotions and thoughts, was recently studied as a stepping stone to performance optimization and personal development. Despite a mistrust of this concept in the sports world, various studies show its benefits within athletes. A major question remains the environment that fosters or hinders the development of self-compassion: when role models extend compassionate attitudes, does it allow performers to respond in more self-compassionate ways? The relationship between self-compassion, mental toughness, and social environment is still unclear and is an important direction for future research within performers. This semi-systematic literature review aims at proposing an overview of the state of the art regarding self-compassion, mental toughness, and the influence of performer’s, and social environments. Sixteen studies were retrieved. We conclude that the number of multi-day intervention programs and longitudinal studies should be increased. The studies should also consider assessing the specific aspects of performance culture and settings. In addition, overall performance-specific measures could be developed to assess general levels of self-compassion. The development of a theoretical framework explaining how self-compassion affects a performer, the role of their entourage and its link to other psychological resources, such as mental toughness, could help to better understand this concept

A first step toward cognitive remediation of voices: a case study.

Several studies have shown that source-monitoring errors are related to verbal hallucinations in schizophrenia. An exploratory pilot study has been carried out to investigate the possibility of training patients in how to avoid errors in source-monitoring. One patient with paranoid schizophrenia and persistent thought insertions was trained for 6 hours to use mnemonic techniques to compensate specific deficits in source-monitoring. Results show that the patient was able to improve his performance and maintain the acquired progress at a 1-month follow-up assessment. These preliminary results are interesting for developing a larger controlled study of cognitive remediation of source-monitoring deficits

Activation émotionnelle chez les troubles de personnalité

Six traitements psychothérapiques des troubles de personnalité sont brièvement présentés dans cette revue de la littérature. Ces traitements se basent sur des modèles théoriques différents, les approches cognitive-comportementale, psychodynamique et interpersonnelle et ont déjà fait leurs preuves cliniques et empiriques en termes de leur efficacité.
