Micro intervención en capital psicológico

Treball Final de Màster Universitari en Psicologia del Treball, de les Organitzacions i en Recursos Humans. Codi: SBE013. Curs acadèmic: 2017/2018The Psychological Capital is associated with the individual psychological resources that people of an organization have to face adversity, propose challenges and achieve goals. The development of Psychological Capital is a great challenge for organizations and a healthy organizational practice. This TFM (Master’s Final Project) aims to make a proposal to implement the Psychological Capital in a volunteer team of the Programa Pisos Solidarios of the Jaume I University from Castellón, Spain. To achieve this goal, it is proposed to perform a micro intervention in Psychological Capital in the team. To analyze and measure the impact of the intervention, the PCQ-12 Questionnaire will be applied pre- and post-intervention. Both, research and theory, supports that the relationship between the components that make up the Psychological Capital (self-efficacy, optimism, hope and resilience) have positive results at the individual and organizational levels. Based on these results, there is an interest to apply it and develop it in the team of volunteers of the Programa Pisos Solidarios.El Capital Psicológico está asociado con los recursos psicológicos individuales que tienen las personas de una organización para afrontar adversidades, proponerse desafíos y cumplir metas. El desarrollo del Capital Psicológico en las personas trabajadoras supone un gran desafío para las organizaciones y una práctica organizacional saludable. El presente Trabajo Final de Máster tiene por objetivo realizar una propuesta para implementar el Capital Psicológico en un equipo de trabajo voluntario del Programa Pisos Solidarios de la Universidad Jaume I. Con el fin de lograr este objetivo, se propone realizar una micro intervención en Capital Psicológico en el equipo. Para analizar y medir el impacto de la intervención se aplicará el Cuestionario PCQ-12 pre y post intervención. Tanto la investigación como la teoría respalda que la relación entre los componentes que conforman el Capital Psicológico (autoeficacia, optimismo, esperanza y resiliencia) tienen resultados positivos a nivel individual y organizacional. En base a estos resultados surge el interés de aplicarlo y desarrollarlo en el equipo de voluntarios del Programa Pisos Solidarios de la UJI

Synaptic transmission between pairs of retinal amacrine cells in culture

We have examined synaptic transmission between isolated pairs of chick GABAergic amacrine cells, maintained in sparse culture and identified by their binding of an amacrine cell-selective antibody. Using the perforated- patch method to whole-cell clamp both cells of a pair, postsynaptic currents were examined for step depolarizations of the \u27presynaptic\u27 cell. Synaptic transmission, frequently reciprocal, was calcium dependent and reversibly blocked by bicuculline. Postsynaptic currents, excluding those due to ohmic electrical coupling, were elicited only for presynaptic voltage steps positive to about -40 mV and were always very noisy, suggesting that they were summed from relatively small numbers of quanta. Postsynaptic currents continued well after the termination of the 100 msec presynaptic voltage step when the step was to -10 mV, or positive to this value. This result is interpreted to imply that presynaptic calcium concentration remains elevated after the membrane is returned to its holding potential. When presynaptic voltages were kept low or else presynaptic voltage was uncontrolled, spontaneous quantal events mediated by GABA(A) receptors could often be seen. Quanta rose quickly (less than 4 msec) and decayed with a mean time constant of 19.3 msec. The amplitude distributions of quantal currents were positively skewed, sometimes showing rare quanta of exceptionally large amplitude. Peak conductance per quantum was about 300 pS, corresponding to the simultaneous opening of only 17 GABA(A) channels and corresponding to a net flux of only 32 x 103 Cl- ions per millivolt of driving force. Estimates of the maximum sustained release rate at individual release sites suggest an upper bound of between 19 and 42 quanta per second

Electrogenic Na-Ca exchange clears Ca\u3csup\u3e2+\u3c/sup\u3e loads from retinal amacrine cells in culture

Calcium influx into cultured retinal amacrine cells is followed by a small, slow, inward current that we show here results from the operation of electrogenic Na-Ca exchange. The activity of the exchanger is shown to correlate with the magnitude of the Ca2+ load and to depend on both the Ca2+ and Na+ gradients. Li+ is unable to substitute for Na+ and in the absence of Na+, slow tail currents are almost entirely suppressed. A rapid change in [K+](o) does not affect the activity of the exchanger, suggesting that only Na+ and Ca2+ are transported. The ratio of charge entering as Ca2+ current to the charge entering as exchange current is highly variable between cells. We suggest that variability results from a variable fraction of Ca2+ load, we estimate typically 40%, being removed by a process other than Na-Ca exchange. This process is likely to involve internal buffering or sequestration since inhibition of the plasmalemmal Ca2+ATPase does not increase the fraction of Ca2+ expelled by the exchanger. Ca2+ loading performed in the absence of Na+(o) generates smaller exchange charge the longer the delay in returning Na+(o) to the neuron. About 30% of exchange charge is lost for a delay of 1 sec

Crack e internação compulsória em debate: impactos da comunicação e informação na vigilância

Health or criminal paradigm? Therapeutic communities or care institutions for people with disorders resulting from psychoactive substances? The starting point of this reflection is the assertion that the mass media of information have put in a singular way of offering space over the world in general and health in particular. One effect of this process is the influence that such news constructions have on the population. With this perspective mapped to news, reports and opinion articles, around the crack and PL 7663 – whose emphasis is on Compulsory Treatment – present in newspaper O Globo, in 2013. As we take journalistic constructs as research object, it became possible to verify how, under the sign of a “crack epidemic”, the journal produced utterances defending legislative changes. Amidst this debate and to a set of contradictions inscribed on it, the secondarization of the psychosocial model of care emerges as a result of a weakening of state surveillance tools, especially since various actions of the health field would be left out of the audit of the Ministry of Health by deleting the stability and transparency that an regulation in line with the Unified Health System provides. The conclusion of this study is that the press “suggests” that, despite hurting some principles legal, Compulsory Treatment was the best way to contain the increase in crack use.Paradigma sanitário ou criminal? Comunidades terapêuticas ou instituições de atenção às pessoas com transtornos decorrentes de substâncias psicoativas? O ponto de partida para esta reflexão é a assertiva de que os meios massivos de informação se revestiram num singular espaço de oferta de sentidos sobre o mundo, em geral, e a saúde, em particular. Um dos efeitos desse processo é a influência que tais construções noticiosas exercem sobre a população. Com esta perspectiva mapeou-se notícias, reportagens e artigos de opinião, em torno do crack e do PL no 7.663 – cuja ênfase recaia sobre a Internação Compulsória – presentes no jornal O Globo, no ano de 2013. Ao tomarmos os construtos jornalísticos como objeto de investigação, tornou-se possível verificar o quanto, sob o signo de uma “epidemia de crack”, o periódico produziu enunciados que defendiam mudanças na legislação. Em meio a esse debate e a um conjunto de contradições nele inscritos, a secundarização do modelo psicossocial de atendimento emerge como resultado de um enfraquecimento dos instrumentos de vigilância do Estado, especialmente porque várias ações do campo sanitário ficariam de fora da auditagem do Ministério da Saúde, suprimindo a estabilidade e a transparência que uma regulação em consonância com o Sistema Único de Saúde enseja. A conclusão do presente trabalho é que a imprensa “sugere” que, a despeito de ferir alguns princípios legais, a Internação Compulsória era o melhor caminho para conter o aumento do uso de crack

Oftalmoplegia internuclear bilateral e fratura de clivus após traumatismo cranioencefálico: relato de caso

Internuclear ophthalmoplegia is a remarkable finding, particularly in patients victims of head injury. The medial longitudinal fasciculus, which is believed to be lesioned in cases of internuclear ophthalmoplegia, has an unique brain stem position and the mechanism involved in brain stem contusions implies a maximal intensity of shearing forces on the skull base. We describe a very rare association of bilateral ophthalmoplegia and clivus fracture following head injury, without further neurological signs. The patient history, his physical examination and the image investigation provide additional evidence to some of the mechanisms of injury proposed to explain post-traumatic internuclear ophthalmoplegia.Oftalmoplegia internuclear é um interessante achado clínico, sobretudo em pacientes vítimas de trauma cranioencefálico. O fascículo longitudinal medial, cuja lesão é responsável pelas alterações observadas na oftalmoplegia internuclear, localiza-se no interior do tronco encefálico. O acúmulo de forças de impacto geradas pelo traumatismo craniano na base do crânio é responsável pela formação de contusões no tronco encefálico. Descrevemos um caso em que se observa rara associação entre oftalmoplegia internuclear bilateral e fratura de clivus em um paciente com traumatismo cranioencefálico leve, sem outras anormalidades neurológicas. A história, o exame físico e a investigação imagenológica do paciente proporcionam evidências adicionais para alguns dos mecanismos propostos para explicar oftamoplegia pós-traumática.63663

Comunicação para a cidadania: linhas de um novo campo

Resenha do livro Comunicação para a cidadania: caminhos e impasses, de Igor Fuser (org)

Efeitos de uma narrativa sobre o Crack: produzindo sentidos, reificando territórios e lugares sociais

Com este artigo, queremos apresentar as bases para reflexão sobre o papel desempenhado pelas narrativas jornalísticas nos contextos contemporâneos. Particularmente, interessa observar o quanto uma determinada substância psicoativa pode ser enquadrada tanto pelo paradigma médico quanto pelo criminal, a partir da forma como é narrada. Paralelamente, destaca-se o quanto as informações presentes na imprensa guardam relação com o imaginário social brasileiro sobre a doença (ou a ação criminosa), os atores sociais, os territórios, especialmente através da forma como os sentidos em torno do crack vêm sendo oferecidos
