Factors Related to the Level of Perceived Quality of Academic and Administrative Services by Users: Case of the National University of the Altiplano, Puno, Peru  [PDF]
Juan Inquilla-Mamani, Fermin F. Chaina-Chura
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105467
Abstract:
The purpose of this research is to determine the conditioning factors of quality of academic and administrative services perceived by users of the National University of the Altiplano (UNA-Puno). In the methodological part, the different statistics are presented as Kendall’s Taub test, Factorial analysis of the components, Factors extraction, Varimax rotation, T test and correlation estimates and multiple linear regression. The study is of transversal design the study sample is made up of students, teachers and administrative staff of the UNA-P, of a simple random type. The measurement instrument applied was the Servqual Questionnaire. For the processing and statistical analysis of the information, the SPSS v. 22 program. The results obtained through the reliability analysis of the Servqual model show us a Cronbach alpha of 0.709, which means that both the instrument and its attributes are reliable and consistent to measure the quality of the service. Considered in the model determine in 67.11% the levels of service quality, R2 is 0.746 and value of F = 0.000. Therefore, the factors identified in the analysis directly and significantly affect the level of perceived quality.
Child Labor and Reproduction of Family Poverty in Puno: A Pending Social Debt  [PDF]
Juan Inquilla Mamani
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104473
Abstract:
Child labor violates the rights of children enshrined in the Convention on the Rights of the Child (CRC) of the United Nations (UN), but also reproduces poverty in our country. In Peru, this type of work is not a novelty, but historical studies reveal that until the 1990s it was viewed with indifference by governments and other instances of society. The present research “Child labor and poverty in Puno”, has as objective: Determine the association between child labor and reproduction of family poverty in Puno. The study areas have been selected, taking into account the places with the highest concentration of children who carry out economic activities with their parents: The area of Salcedo “the brickworks in the Rinconada”, Jr. Los Incas and the surroundings of the stadium “ETB”, the Bellavista market and Mercado Union and Dignidad, as well as some parks and main streets where they carry out their economic activities informally. The Study Method is inductive of correlational-longitudinal design. Sample: The universe of the population under study is made up of adults who were formerly street children and adolescents in the city of Puno. Results: Child labor interferes in many ways: First, it decapitalizes in two to three years of study approximately with respect to those that do not work; second, the effort that work demands them has a negative impact on school continuity in the future. When not reaching the expected level in education, the possibility of repetition increases, which in turn generates delay and facilitates the desertion and consequently by the constant repetitions and desertions makes possible the definitive abandonment of the school. Therefore, child labor in the current conditions is twice the fundamental rights of children, places conditions of informality when they are adults and reproduces family poverty in our country in a generational manner.
The Social Policies and Programs of the State from the Perspective of Multidimensional Poverty in the Puno Region  [PDF]
Juan Inquilla Mamani
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104474
Abstract:
This research focuses on evaluating coverage results, targeting mechanisms, coherence of objectives, goals and actions developed by social programs, as well as the social impact expressed in the reduction of extreme poverty and the improvement of the quality of life of the target population in the Puno region. The method used is Differences in Differences; this design allows us to incorporate some degree of pre-existing differences between the treatment group and the control group, controlling for observable characteristics of the latter. The results found at the level of the region as a result of the implementation of the evaluated programs show a positive impact on the components evaluated: Targeting system (leaks and subcodes); achievement and fulfillment of program objectives and goals; transfer and delivery of economic subsidies and improvement of their welfare; food attention to the target population (Qaliwarma and Vaso de Leche), which shows the importance of social programs in favor of the poorest population and the extreme poor. Finally, we analyze whether the effect of receiving the monetary transfer on the monthly income in the household, which is directly related to the improvement of the users’ welfare in both the “Together” and “Pension 65” programs, however, these effects are heterogeneous when presenting components and the reduction of multidimensional poverty in the Puno region.

Abstract: lake titicaca's ecosystem and that of its tributaries in puno (peru) are being disturbed by heavy metals resulting from emergent mineral activity. biological processes involving microorganisms such as yeasts (bioremediation) are being used for controlling and reducing such pollution. this research was aimed at evaluating saccharomyces cereviceae's lead biosorption capacity in aqueous solutions and evaluating the influence of two ph levels on biosorption. two s. cereviceae concentrations (cel/ml) were tested; these concentrations were quantified in a haemocytometer and then put into a solution having a known lead concentration (5 and 25 mg/l). lead concentrations were read after 5, 60 and 120 minutes. the results revealed that the best biosorption level was obtained with a 5 x 106 cel/ml s. cereviceae concentration at 5.14 ph. s. cereviceae thus constitute a good alternative for lead biosorption; however, its validation in peruvian altiplano field conditions remains to be tested.

Abstract: Studies of lead biosorption by Saccharomyces cereviceae in aqueous solutions Resumen: El ecosistema del lago Titicaca (Puno, Perú) y sus tributarios, viene siendo perturbado por metales pesados producto de la actividad minera emergente. Para controlar y reducir la contaminación existen procesos biológicos llevados a cabo por microorganismos como las levaduras (biorremediación). Este trabajo de investigación tiene como objetivos evaluar la capacidad de bioadsorción de plomo mediante Saccharomyces cereviceae en soluciones acuosas y la influencia de dos niveles de pH durante la bioadsorción. Para esto se ensayaron dos concentraciones de S. cereviceae (cel/mL), las cuales fueron cuantificadas por un hemocitómetro y luego traspasadas a una solución con concentraciones conocidas de plomo (5 y 25 mg/L). Se realizaron lecturas de las concentraciones de plomo a los 5, 60 y 120 minutos. La mayor capacidad de bioadsorción resultó cuando S. cereviceae estaba a una concentración de 5 x 106 cel/mL, y el pH óptimo fue de 5,14. Se concluye que S. cereviceae constituye una buena alternativa para la bioadsorción de plomo, quedando abierta su validación en condiciones de campo en el altiplano peruano. Palabras clave: bioadsorción, plomo, levadura.

Control of Leaf Spot Diseases on Ecotypes of Faba Bean (Vicia faba L.) Produced in the Andean Region of Bolivia  [PDF]
M. Coca-Morante, F. Mamani-álvarez
American Journal of Plant Sciences (AJPS) , 2012, DOI: 10.4236/ajps.2012.38139
Abstract: The basin of Lake Titicaca is a faba bean-producing microregion of Bolivia where the crop is destined for export. The most commonly cultivated ecotypes “Gigante de Copacabana” and “Usnayo” are affected by diseases that can cause production losses. The aims of the present work were to identify the causal agents of leaf spot affecting these ecotypes, to record disease intensity levels, and to estimate their effect on production. In 2004 and 2005, leaflet, stem and pod samples were taken from faba bean plants with leaf spot growing in the Lake Titicaca area, and from plants in an experimental plot established to determine the effect of five different treatments on production and disease intensity: T1 = Control; T2 = seed treatment with Trichoderma sp. + alternate foliar spraying with benomyl and mancozeb; T3 = seed treatment with fludioxanil/metalaxyl M + alternate foliar spraying with benomyl and mancozeb; T4 = foliar spraying with Trichoderma sp.; T5 = alternate foliar spraying with cymoxanyl and mancozeb-chlorothalonil. Microscopic analysis of the samples revealed the presence of new fungal pathogens for faba beans in Bolivia (Cladosporium sp., and Lepthosphaerulina sp.) as well as emerging fungal pathogens (Botrytis cinerea, B. fabae, Ascochyta fabae, Alternaria sp. and Cercospora sp.). None of the treatments affected the disease progression curve (DPC) for incidence, although effects were seen with respect to disease severity. The seed + foliar treatments (T2 and T3) were more effective at controlling disease than leaf treatments on their own (T4 and T5). Modelling analysis showed faba bean leaf spot disease to be moderately destructive. Compared to chemical treatments, biocontrol with Trichoderma spp. preliminary was found to provide good control of the disease. Losses due to leaf spot disease of 36% were recorded, and a strong correlation detected between yield and disease severity.
