The swindle crime: a necessary normative construction of its elements

The present work exposes a review about the performance of the “traditional” thesis(Naturalistic) of the swindle crime in front of the needs of the present’s Political Policy.For this system, the various frauds’ elements require a causal relationship. Today itmight be wondered whether this solution is desirable, i.e. whether respond efficientlyto the problematic assumptions that the contemporary business practices raises.

Some elements for the construction of a definition of human rights

This article seeks to demystify the foundations of rights. It looks at the search for some systemic differentiation. It emphasizes effectiveness, legitimacy, the importance of convention and of political participation as common elements of the different theoretical approaches to human rights. By analysing these elements it is possible to build the term “human rights” as a concept capable of being measured accurately by studying the effectiveness of legal rules as applied to human rights in specific contexts.

Evaluación del uso de plaguicidas en la actividad agrícola del departamento de Putumay

El objetivo fue identificar los plaguicidas empleados por agricultores del Putumayo, evaluando el cumplimiento de las disposiciones legales sobre manejo de éstos y las medidas de protección personal. Metodología: estudio observacional descriptivo de campo, en zonas de cultivos ilícitos. Resultados: se evaluaron 490 sujetos, de los cuales se identificaron como expuestos a plaguicidas el 25,9%. La distribución por edad de los expuestos a plaguicidas fue: 1-10 años (19,7%), 10-18 (18,1%), 18-35 (33,9%), 35-55 (23,6%) y más de 55 años (4,7%). La mayoría de productos reportados son categoría toxicológica I. De las 109 personas que realizan labores de formulación, el 95,4% utilizan un método manual sin guantes. De los 115 sujetos que hacen aplicación, 76,5% utilizan bomba de espalda y 23,5% bomba estacionaria. El 97,6% de expuestos no emplea elementos de protección personal. Los envases vacíos son dispuestos de manera inadecuada. En los últimos seis meses se han presentado 198 contactos accidentales en 72 individuos. Conclusiones: es preocupante encontrar el uso inadecuado de insecticidas y herbicidas tóxicos y el desconocimiento de la normatividad vigente. Es recomendable que entidades académicas, entes gubernamentales e industria de agroquímicos emprendan esfuerzos para cumplir a cabalidad su función de educación, control y vigilancia sobre el uso de plaguicidas, sin importar si el producto cultivado es lícito o ilícito.

Evaluation of the Toxic Effect from Eupatorium Microphyllum L.F. (Asteraceae) Extracts on Aedes Aegypti Larvae (Diptera: Culicidae) in Laboratory Conditions

In the present work the toxic activity of extracts of Eupatorium microphyllum L.F. was evaluated on 4th instar larvae of the mosquito Aedes aegypti (Linneaus), under laboratory conditions. Aqueous extracts were utilized in concentrations of 500 mg L-1, 1,500 mg L-1 and 2,500 mg L-1 and acetone in concentrations of 10 mg L-1, 20 mg L-1, 30 mg L-1, 40 mg L-1and 50 mg L-1. The bioassays were carried out for triplicate each one with 20 larvae, exposed for 24 hours to 150 mL of solution. In all the bioassays were employed control groups. In the evaluation of the acetone extracts, a negative control was employed to avoid that the mortality of the larvae to occur on account of the solvent. The Aqueous extracts showed low moderate action in the mortality of larvae, less than 20%. On the contrary, the action of the acetone extracts was observed to 10 and 20 mg L-1with 15% of mortality, while to 30 and 40 mg L-1 were registered 22 to 38% of mortality. However, to 50 mg L-1 the mortality was of 95.4% with highly significant statistical results. The concentrations of the acetone extracts showed to be the most efficient for the control of the mosquitoes selected. Both types of extracts showed toxic effect in larvae of A. aegypti, nevertheless, greater effect in the acetone extracts was observed relating to the aqueous extracts of E. microphyllum, which constitutes a viable alternative in the search of new larvicides from composed natural.
