The municipal public services are activities carried out by the governments of the municipalities in order to satisfy collective needs. From an economic conception we can understand municipal governments as production units, which make use of their own inputs (resources) to generate a set of outputs (public services) that meet the needs of consumers (inhabitants of the municipality). This process of production of public services has an immediate impact on the quality of life of citizens. For this reason it becomes essential to estimate the efficiency in the use that municipal governments make of public resources to provide basic services of collective interest. The objective of this research is to identify the degree of efficiency of municipal governments in the use of investment expenditure and the cost of personal services in the provision of public lighting services, garbage collection and public safety to citizens of the state of Michoacán in the year 2014. In order to achieve this objective, the Data Envelopment Analysis (DEA) method was used, through which an efficiency frontier was estimated that allowed calculating the efficiency levels of the 113 municipalities of Michoacán to produce public services. An additional benefit of the DEA method is that it generates additional information (slacks variables) to propose to the inefficient municipalities improvement actions based on the results of the efficient municipalities. The results of the model showed that only 22 municipalities (19.47% of the total) had a degree of efficiency of 100% in the management of their resources for the production of municipal public services. From the results, various improvement actions are proposed based on the slacks variables so that the inefficient municipalities improve their policies regarding public services.

Los servicios públicos municipales son actividades que llevan a cabo los gobiernos de los municipios con el fin de satisfacer necesidades colectivas. Desde una concepción económica podemos entender a los gobiernos municipales como unidades de producción, que hacen uso de sus propios inputs (recursos) para generar un conjunto de outputs (servicios públicos) que satisfacen las necesidades de los consumidores (habitantes del municipio). Este proceso de producción de servicios públicos repercute de forma inmediata en la calidad de vida de los ciudadanos. Por tal razón se vuelve imprescindible la medición de la eficiencia en el uso que los gobiernos municipales hacen de los recursos públicos para proveer servicios básicos de interés colectivo. El objetivo de esta investigación consiste en identificar el grado de eficiencia de los gobiernos municipales en la utilización del gasto de inversión y del gasto de servicios personales en la provisión de los servicios de alumbrado público, recolección de basura y seguridad pública a los ciudadanos del estado de Michoacán en el año 2014. Para lograr este objetivo se utilizó el método del Análisis de la Envolvente de Datos (DEA), a través del cual, se estimó una frontera de eficiencia que permitió calcular los niveles de eficiencia de los 113 municipios de Michoacán para producir servicios públicos. Una bondad adicional del método DEA es que genera información adicional (variables slacks) para proponer a los municipios ineficientes acciones de mejora a partir de los resultados de los municipios eficientes. Los resultados del modelo arrojaron que solo 22 municipios tuvieron un grado de eficiencia del 100% en el manejo de sus recursos para la producción de servicios públicos municipales. De los resultados se proponen diversas acciones de mejora a partir de las variables slacks para que los municipios ineficientes mejoren sus políticas en materia de servicios públicos.

Behavior of private retailers in a regulated input market: An empirical analysis of the fertilizer subsidy policy in Nepal

Shriniwas Gautam Dyutiman Choudhary Dil Bahadur Rahut (2022, [Artículo])

The private sector in Nepal participates in the regulated import and distribution of three types of subsidized fertilizer. However, almost 55% of the agrovets (family-owned microenterprises) that retail agricultural inputs do not comply. Many farmers rely on the fertilizer purchased through these agrovets, including subsidized ones. There is no private sector importer of the three types of fertilizer covered by the subsidy program, which indicates that the agrovets either acquire these through leakage in the government distribution system or through illegal cross-border trade from India, both of which are considered legal noncompliance. We discern the determinants for this noncompliant behavior of agrovets using logistic regression. The results from logistic regression suggest that the agrovets that are more likely to comply are registered, have membership in business associations, and have a higher number of competitors. Those with diversified business portfolios and covering a greater number of districts are less likely to comply. Key informants, consisting of both public and private sector stakeholders, were solicited for their views on solving this noncompliant behavior. The private sector unanimously asserts the need for deregulation of fertilizer imports and the participation of agrovets in the distribution of the subsidized fertilizer. In contrast, the public sector is skeptical of the ability and trustworthiness of the private sector in the import and distribution of quality fertilizer. We propose a middle ground to mitigate private sector noncompliance and suggest a policy revisit to increase the fertilizer supply and distribution efficiency.

Universal fixation system for pad printing of plastic parts

JOSE ALEJANDRO FERNANDEZ RAMIREZ (2023, [Artículo])

Pad printing is used in automotive, medical, electrical and other industries, employing diverse materials to transfer a 2D image onto a 3D object with different sizes and geometries. This work presents a universal fixation system for pad printing of plastic parts (UFSP4) in response to the needs of small companies that cannot afford to invest in the latest technological advances. The UFSP4 comprises two main subsystems: a mechanical support system (i.e., support structure, jig matrix and braking system) and a control system (i.e., an electronic system and an electric-hydraulic system). A relevant feature is the combination of a jig matrix and jig pins to fixate complex workpieces with different sizes. Using finite element analysis (FEA), in the mesh convergence, the total displacement converges to 0.00028781 m after 12,000 elements. The maximum equivalent stress value is 1.22 MPa for the polycarbonate plate in compliance with the safety factor. In a functionality test of the prototype performed in a production environment for one hour, the jigs fixed by the plate did not loosen, maintaining the satisfactory operation of the device. This is consistent with the displacement distribution of the creep analysis and shows the absence of the creep phenomenon. Based on FEA that underpinned the structural health computation of the braking system, the prototype was designed and built, seeking to ensure a reliable and safe device to fixate plastic parts, showing portability, low-cost maintenance and adaptability to the requirements of pad printing of automotive plastic parts.

A simple extension to the CMASA method for the prediction of catalytic residues in the presence of single point mutations

David Israel Flores Granados (2014, [Artículo])

The automatic identification of catalytic residues still remains an important challenge in structural bioinformatics. Sequence-based methods are good alternatives when the query shares a high percentage of identity with a well-annotated enzyme. However, when the homology is not apparent, which occurs with many structures from the structural genome initiative, structural information should be exploited. A local structural comparison is preferred to a global structural comparison when predicting functional residues. CMASA is a recently proposed method for predicting catalytic residues based on a local structure comparison. The method achieves high accuracy and a high value for the Matthews correlation coefficient. However, point substitutions or a lack of relevant data strongly affect the performance of the method. In the present study, we propose a simple extension to the CMASA method to overcome this difficulty. Extensive computational experiments are shown as proof of concept instances, as well as for a few real cases. The results show that the extension performs well when the catalytic site contains mutated residues or when some residues are missing. The proposed modification could correctly predict the catalytic residues of a mutant thymidylate synthase, 1EVF. It also successfully predicted the catalytic residues for 3HRC despite the lack of information for a relevant side chain atom in the PDB file. © 2014 Flores et al.
