Evaluación de bioproductos para la producción de tomate (Solanum lycopersicum, Mill) bajo sistema de cultivo protegido
Terry,Elein; Ruiz,Josefa;
Cultivos Tropicales , 2008,
Abstract: indisputable ecological agriculture advances are closely linked to the proven risk, provoked to human health by foods containing toxic residuals derived from pesticides and mineral fertilizers, which has encouraged an international movement, intended to improve its biological quality by means of using available natural resources in agroecosystems. cuba is not kept out of this situation and proposes some ecological alternatives to manage agricultural crops developed under a protected cultivation system, which are great chemical consumers. this work was carried out under protected cultivation housing conditions aimed at studying the effect of mycorrhizae and brassinosteroid analogues as ecological alternatives for tomato production under such productive system. there were seven completely randomized treatments referred to the single and combined application of bioproducts as well as its combination with mineral fertilization, so that they allowed reducing the mineral fertilization applied to crop under these conditions. according to results, when there are statistical differences compared to production control, ecological product combination stimulates plant growth and crop production. the combined application of mycorrhizae-brassinosteroid analogues (three times) + 50 % mineral fertilization enabled to obtain a larger amount of bunches (11.2) and fruits (21.0) per plant, with a fruiting percentage of 92.4 %, leading to an agricultural yield of 51.46 t.ha-1, the 50 % mineral fertilization reduction being significant to be applied under a protected cultivation system
Democratizar la ciencia jurídica (cómo se puede conjugar un saber dogmático con las exigencias de la inteligencia colectiva)
Josefa Dolores Ruiz Resa
Cuadernos Electrónicos de Filosofía del Derecho , 2011,
Abstract: RESUMEN Las exigencias de adaptabilidad y flexibilidad que el EEES impone a las profesiones jurídicas, desde la defensa de una sociedad del conocimiento que se caracteriza por la informatización de casi todas las esferas de la actividad humana, deberían contemplarse como una oportunidad para que la ciencia jurídica redefina su estatuto. Por el momento, esta ciencia apenas ha abandonado los presupuestos de transmisión académica, teórica y acrítica, que contribuyen a mantener una rigidez ajena a nuevas necesidades sociales. Sin embargo, el éxito de los cambios a los que se ven abocados los estudios y las profesiones jurídicas va a depender de algunos cambios en el mismo saber que se transmite. ABSTRACT The new knowledge society is characterized by the computerization of almost every sphere of human activity. In this context, the demands for adaptability and flexibility imposed by the EHEA on the legal profession should be seen as an opportunity to redefine the legal science status. For the moment, this science has barely left the presuppositions of theoretical, uncritical academic teaching. But this contributed to manteining an inflexibility which is alien to new social needs. However, the success of the changes we are forced to introduce in our studies and the legal profession will depend on other changes in the knowledge itself that is conveyed.
Quand la politique intervient dans l’économie

Revue d’études Benthamiennes , 2010, DOI: 10.4000/etudes-benthamiennes.225
Abstract: IntroductionDe nos jours, l’économie semble avoir besoin de la politique. Au début du XXIème siècle, la crise économique exige que les états régulent les processus économiques, autrement dit, qu’il y ait une politique économique et sociale. Peut-être est-on face à un défi aux postulats du libéralisme. Mais est-il vrai que le libéralisme s’opposait à l’intervention de l’état dans le domaine économique ? Si l’on revoit l’ uvre que John Stuart Mill avait consacrée à l’économie, on peut constater...
Consecuencias psicosociales de la implementación de las políticas de acción positiva para los no beneficiarios: efectos diferenciales según el grupo beneficiario
Josefa Ruiz Romero,Miguel C. Moya Morales
Revista Interamericana de Psicología , 2005,
Abstract: Mediante un estudio de simulación experimental se analizan las consecuencias que tiene para las personas no beneficiarias la implementación de una medida de acción positiva en el ámbito laboral. Se les pidió a 180 participantes que imaginaran una situación en la cual recibían una contestación negativa a su solicitud de empleo. En la condición de acción positiva se informaba de que la pertenencia grupal de los candidatos había sido un criterio básico para la contratación, mientras que en la condición control no se hacía explícito el criterio de selección. Se analizaron algunas consecuencias psicosociales de la acción positiva (percepción del estereotipo laboral del exogrupo, actitud hacia la acción positiva) así como diversas reacciones psicológicas de los participantes (ansiedad, hostilidad, depresión y autoestima). También se examinó si estos efectos variaban en función de la naturaleza del estigma del grupo beneficiario de la acción positiva (mujer, persona con discapacidad, gitano o inmigrante). Los resultados revelaron que la aplicación de la acción positiva conllevó un deterioro del estereotipo laboral del grupo beneficiario, una actitud más desfavorable hacia la acción positiva y consecuencias psicológicas negativas. No obstante, la magnitud de este efecto varió en función del grupo diana de la acción positiva
Adolescent witnesses in cases of teen dating violence: An analysis of peer responses
Josefa Ruiz,Francisca Exposito,Helena Bonache
European Journal of Psychology Applied to Legal Context , 2010,
Abstract: Gender violence is a serious problem that also affects the adolescent population (González & Santana, 2001). The victims of such violence in adolescence, should they seek help, rely primarily on their peers and rarely report it to adults (Weisz et al., 2007). The responses or reactions of avoidance, minimization or protection that their peers may have contribute to the victim maintaining or breaking the "unhealthy" relationship. An experimental study was designed to examine the reactions of adolescents in the event that they are witness to an episode of violence (verbal and physical aggression) towards a friend. The main objective was to analyze the differences in their reactions according to sex of the witness, familiarity with the perpetrator (stranger vs. a friend) and the relationship between aggressor and victim (a date, romantic partner.) An exploratory analysis of the influence of the witnesses’ sexist beliefs (hostile and benevolent) on these reactions was also performed. Thus, more negative reactions were found (greater passivity and less empathy) among men in the case where the victim maintained a relationship with the offender than in the case of a date, especially if the perpetrator was a stranger. Also, in the girls more avoidance responses were found when the violent episode occurred between members of a couple on a date. Finally, the practical implications of the findings are discussed, highlighting the need to include guidelines in programs against gender violence among adolescents on how to behave if in relation to the victim when they are witnesses of gender violence.

Revista Colombiana de Biotecnología , 2010,
Abstract: bioproduct use has gradually increased in the agriculture of countries promoting change towards an insecticide model more in harmony with the environment. the present work was aimed at evaluating the response of a tomato crop to the application of gluticid? (a bioproduct obtained from pseudomona aeruginosa, pss strain). the experiments were carried out in experimental areas belonging to the cuban national institute of agricultural sciences (inca); five treatments were studied, four involving gluticid? application and a test treatment. the gluticid? treatments were carried out by submerging the seed with the product (15 and 30 minutes) and then a second foliate application of the bioproduct was carried out. some growth indicators were evaluated and agricultural yield was determined. the results confirmed the bioproduct?s effectiveness; a single application of gluticid? involving 15 minutes? submersion stood out as being the most effective treatment. this confirmed this bioproduct?s effectiveness in obtaining vigorous plants and obtaining acceptable yields.

Revista Colombiana de Biotecnología , 2010,
Abstract: El uso de bioproductos se incrementa gradualmente en la agricultura de países que propugnan un cambio hacia un modelo en armonía con el medioambiente. El presente trabajo tuvo como objetivo evaluar la respuesta del cultivo del tomate a la aplicación del bioproducto Gluticid , obtenido a partir de metabolitos activos de Pseudomona aeruginosa. Los experimentos se desarrollaron en áreas experimentales del Instituto Nacional de Ciencias Agrícolas (INCA) de Cuba, y se estudiaron cinco tratamientos, cuatro con la aplicación de Gluticid y un tratamiento testigo (sin aplicación del producto). Los tratamientos con Gluticid (5 g.L-1), se realizaron imbibiendo las semillas con el producto (15 y 30 min) y a su vez se realizó una segunda aplicación foliar del bioproducto. En el cultivo se evaluaron algunas variables de crecimiento y desarrollo, y se determinó el rendimiento agrícola. Los resultados mostraron la efectividad del bioproducto, destacándose el tratamiento que recibió la aplicación de Gluticid una sola vez con 30 min de imbibición, confirmándose la efectividad de este bioproducto en la obtención de plantas más vigorosas, así como un estímulo en el crecimiento y desarrollo de las plantas con la consiguiente obtención de rendimientos aceptables. Palabras clave: bioproducto, tomate, crecimiento, desarrollo, rendimiento. Abstract: The use of bioproducts has increased gradually in the agriculture of countries that support a change toward a model in harmony with the environment.

The sustainability of the system of pensions in Spain. La sostenibilidad del sistema de pensiones en Espa a

European Journal of Education and Psychology , 2009,
Abstract: The aim of this work is to present the important demographic changes that Spain has experimented in the last 50 years, which are marked by an inescapable process of population aging. This fact has been minimized by the large number of foreigners who comes to Spain. Although the guarantee of the pension system is a fact, during the next two decades, it’s needed to carry out some reforms with relative urgency, following the models that the most European countries have already carried out. The purpose of these reforms must be clear and precise, because it is a fact that in the following years will be a great number of retirees and is not so clear that a proportional increase in the number of participants will happen. With respect to the measures to be taken, we think that all of them must be directed to improve the relation between the contributions during the phase of activity and the amount of benefits, once retirement occurs. Finally, it would be desirable that any pension system’s reform would be accompanied by effective measures of economic policy which increase employment, as well as its quality. Key words: Ageing, pensions reform, retirement age, dependency ratio. El objetivo de este trabajo consiste en presentar los importantes cambios demográficos que ha sufrido Espa a en los últimos cincuenta a os, marcados por un ineludible proceso de envejecimiento poblacional, que se ha contrarrestado tímidamente por la afluencia puntual de extranjeros. Aunque la garantía del sistema de pensiones es un hecho, durante las dos próximas décadas, hay que efectuar reformas con relativa urgencia, a imagen y semejanza de las ya realizadas en la mayoría de países europeos. La finalidad de estas reformas debe ser clara y decidida, pues es una certeza que en los próximos a os se atenderá a un número mucho mayor de jubilados y no está suficientemente claro que se produzca un aumento proporcional en el número de afiliados. En cuanto al tipo de medidas a adoptar, creemos todas ellas deben de ir encaminadas a mejorar la relación entre las cotizaciones durante la etapa de actividad y la cuantía de las prestaciones, una vez que se produce la jubilación. Finalmente, sería deseable que toda reforma del sistema de pensiones fuese acompa ada de medidas efectivas de política económica que incrementen el empleo, así como la calidad del mismo. Palabras clave: Envejecimiento, reforma de las pensiones, edad de jubilación, tasa de dependencia.

Abstract: Objective: To examine the association between elevated levels of red cell distribution width (RDW) and cardiovascular risk factors (CVRF) and metabolic syndrome (MS) in HIV-patients. Methods: Cross-sectional study including all asymptomatic HIV-outpatients under follow-up during 2007. Patients completed a questionnaire about CVRF, underwent a physical examination, and an 8-hour fasting blood analysis. Elevated RDW was defined as ≥75th percentile. Patients with and without an elevated RDW were compared. Results: 666 patients (79.3% men) were included: mean age 44.7 years, mean CD4 506/mm3 and 87.5% on antiretroviral therapy (85.3% with undetectable viral load). Mean RDW was 13.7% (range: 7.7% - 33.6%; 75th percentile, 14.1%). The prevalence per quartile of MS was 15.7%, 9.3%, 18.8% and 16.6% and of patients with CVRF > 20% was 8.4%, 4.0%, 4.4%, and 6.4%, respectively (p > 0.05); 23.4% of the patients had an elevated RDW (>14.1%). The top percentile of RDW was associated with AIDS (OR 1.6; 95% CI, 1.0 - 2.4; p = 0.02), detectable viral load (OR 1.5; 95% CI, 1.01 - 2.4; p = 0.04) and hypertension (OR 2.3; 95% CI, 1.4 - 4.0; p = 0.001). Conclusions: In HIV-outpatients, higher RDW is related with detectable viral load and with AIDS. Although it was associated with hypertension, we found no relation with MS nor with higher cardiovascular risk.
