El tungsteno y las huellas del colonialismo en el Perú

El artículo propone una reflexión frente a las diversas expresiones del colonialismo que se manifiestan en El tungsteno, la novela social de Vallejo, destacando su plano político y estable­ciendo un paralelo con el pensamiento crítico de Aimé Césaire. Se busca de­mostrar que la iniciativa de reivindicar al mundo indígena desde el marxismo-leninismo constituye, en últimas, una variable más del colonialismo

Sanciones por infracciones contra la Salud y Seguridad en el trabajo en empresas de Perú, 2011-2013

Objetivo: Determinar las características de sanciones realizadas por la Superintendencia Nacional de Fiscalización (SUNAFIL) del Ministerio de Trabajo (MINTRA) peruano. Metodología: Estudio descriptivo de análisis usando la base de datos del MINTRA acerca de sanciones realizadas entre el 2011-2013. Se describieron datos de la región de la empresa, año, cantidad de trabajadores afectados y tipo de sanción. Resultados: Las empresas del Departamento de Lima tuvieron 3.583.473,45 nuevos soles (1.013.712,43 €) en multas en los 3 años. La sanción más común fue por el incumplimiento de implementar un sistema de gestión o no tener un reglamento de seguridad y salud en el trabajo. La norma 27.15 fue la que generó mayor cantidad de multas, por no cumplir las obligaciones relativas al seguro complementario de trabajo de riesgo. Conclusión: Este estudio puede servir de guía a las empresas, para que sepan los puntos que son más sancionados por la entidad peruana que fiscaliza el cumplimiento de la norma, para que la salud y seguridad de los trabajadores sean de calidad.

Soberanía estatal en el marco del régimen internacional de DDHH: un análisis de la derogación de leyes de amnistía como consecuencia de la injerencia de la corte IDH en Perú

Esta monografía busca analizar la figura de la soberanía estatal en el marco del Régimen Internacional de DDHH a través del caso de derogación de Leyes de Amnistía en Perú por parte de la Corte Interamericana de Derechos Humanos. Así, se pretende identificar la afectación de la soberanía del Estado peruano como consecuencia de la declaración de incompatibilidad y carencia de efectos jurídicos de las leyes de amnistía por parte de la Corte Interamericana, en la sentencia Barrios Altos c. Perú. En ese sentido, estudiando el concepto de soberanía estatal, en particular en la rama del poder legislativo, y su relación con las instituciones internacionales de carácter interestatal como la Corte Interamericana de Derechos Humanos, podremos señalar cómo las decisiones de la Corte limitan el poder soberano de los Estados.

A ‘cost-per-wear’ model based on contact lens replacement frequency

Purpose: The aim was to construct and advise on the use of a cost-per-wear model based on contact lens replacement frequency, to form an equitable basis for cost comparison. ---------- Methods: The annual cost of professional fees, contact lenses and solutions when wearing daily, two-weekly and monthly replacement contact lenses is determined in the context of the Australian market for spherical, toric and multifocal prescription types. This annual cost is divided by the number of times lenses are worn per year, resulting in a ‘cost-per-wear’. The model is presented graphically as the cost-per-wear versus the number of times lenses are worn each week for daily replacement and reusable (two-weekly and monthly replacement) lenses.---------- Results: The cost-per-wear for two-weekly and monthly replacement spherical lenses is almost identical but decreases with increasing frequency of wear. The cost-per-wear of daily replacement spherical lenses is lower than for reusable spherical lenses, when worn from one to four days per week but higher when worn six or seven days per week. The point at which the cost-per-wear is virtually the same for all three spherical lens replacement frequencies (approximately AUD$3.00) is five days of lens wear per week. A similar but upwardly displaced (higher cost) pattern is observed for toric lenses, with the cross-over point occurring between three and four days of wear per week (AUD$4.80). Multifocal lenses have the highest price, with cross-over points for daily versus two-weekly replacement lenses at between four and five days of wear per week (AUD$5.00) and for daily versus monthly replacement lenses at three days per week (AUD$5.50).---------- Conclusions: This cost-per-wear model can be used to assist practitioners and patients in making an informed decision in relation to the cost of contact lens wear as one of many considerations that must be taken into account when deciding on the most suitable lens replacement modality.

Fair flow control of ABR service by per-VC virtual queuing

In this paper, a rate-based flow control scheme based upon per-VC virtual queuing is proposed for the Available Bit Rate (ABR) service in ATM. In this scheme, each VC in a shared buffer is assigned a virtual queue, which is a counter. To achieve a specific kind of fairness, an appropriate scheduler is applied to the virtual queues. Each VC's bottleneck rate (fair share) is derived from its virtual cell departure rate. This approach of deriving a VC's fair share is simple and accurate. By controlling each VC with respect to its virtual queue and queue build-up in the shared buffer, network congestion is avoided. The principle of the control scheme is first illustrated by max–min flow control, which is realised by scheduling the virtual queues in round-robin. Further application of the control scheme is demonstrated with the achievement of weighted fairness through weighted round robin scheduling. Simulation results show that with a simple computation, the proposed scheme achieves the desired fairness exactly and controls network congestion effectively.

Compensation for lost services of an employee : pure economic loss and per quod action

Under the common law an employer may take action against a defendant for the loss of an employee’s services due to the act of the defendant (per quod servitium amisit - by reason of which the services were lost). The High Court has recently affirmed the existence of this ancient tort in Barclay v Penberthy [2012] HCA 40.

PV string per-module maximum power point enabling converters

Many grid connected PV installations consist of a single series string of PV modules and a single DC-AC inverter. This efficiency of this topology can be enhanced with additional low power, low cost per panel converter modules. Most current flows directly in the series string which ensures high efficiency. However parallel Cúk or buck-boost DC-DC converters connected across each adjacent pair of modules now support any desired current difference between series connected PV modules. Each converter “shuffles” the desired difference in PV module currents between two modules and so on up the string. Spice simulations show that even with poor efficiency, these modules can make a significant improvement to the overall power which can be recovered from partially shaded PV strings.

Second-order elastic finite element analysis of steel structures using a single element per member

Finite element frame analysis programs targeted for design office application necessitate algorithms which can deliver reliable numerical convergence in a practical timeframe with comparable degrees of accuracy, and a highly desirable attribute is the use of a single element per member to reduce computational storage, as well as data preparation and the interpretation of the results. To this end, a higher-order finite element method including geometric non-linearity is addressed in the paper for the analysis of elastic frames for which a single element is used to model each member. The geometric non-linearity in the structure is handled using an updated Lagrangian formulation, which takes the effects of the large translations and rotations that occur at the joints into consideration by accumulating their nodal coordinates. Rigid body movements are eliminated from the local member load-displacement relationship for which the total secant stiffness is formulated for evaluating the large member deformations of an element. The influences of the axial force on the member stiffness and the changes in the member chord length are taken into account using a modified bowing function which is formulated in the total secant stiffness relationship, for which the coupling of the axial strain and flexural bowing is included. The accuracy and efficiency of the technique is verified by comparisons with a number of plane and spatial structures, whose structural response has been reported in independent studies.
