Haciendo viable la minería peruana: el caso de Minera Gold Land
Authors:   Universidad ESAN, Lima, Peru, Centeno Rojas Adolfo
Published: September 2021

Although mining is at present a signifi cant source of foreign currency fl ows to Peru, it went through times of crisis when metal quotations dropped. Many international mining majors weathered the crises with the fi nancial backing of their parent companies or fi nancial multilaterals, and their operative economies of scale. In the wake of the crisis, some small and intermediate mining companies closed their operations, leaving behind a negative impact of their communities and a degraded environment. Yet, other companies, thanks to the commitment of their shareholders, workers and local banks, introduced a number of initiatives to negotiate the crisis. The story of Gold Land Mining illustrates the case of those companies that managed to survive during very dire times.

Published: September 2021

This is a qualitative study about how to conduct business in Peru. It is based on 47 semi-structured questionnaires on pointed negotiation experiences in which a Peruvian side was involved. The information was classified into 23 items about the customs, tactics, concepts, expectations, beliefs and values that occur in conflict and negotiation processes in Peru. Here was found a culture very similar to that widespread in Latin America: the dominance of haggling as a negotiating process, based on an unreasonable request at the beginning that is to be adjusted slowly. Cordial relations are preferred in an informal atmosphere; it is customary to not do much preparation for the negotiation and recourse to cunning and power more often than to objective technical criteria. In this culture emotions are expressed, and uncertainties have generated a great deal of flexibility in negotiations. The results must be validated by further analysis. This study is part of an extensive research on intercultural negotiation.

Published: September 2021

Credible demonstration of policy or program impacts depends on understanding the distinction between inputs, outputs, outcomes and indicators. Moreover, in order to be trusted, public reports on a programs’ performance need to focus more selectively on identifying the key measures of performance. In the first place, the aim of the article is to provide those involved in the practice of program evaluation with enhanced understanding of the current literature, reports and documentation on estimating impacts and results of government programs and policies. Secondly, it is designed to share definitions and guidelines used to determine economic impacts. Finally, this article includes current best practices involved in measuring incremental impacts, all of which, we contend, enable program evaluation staff providing them with new ways of approaching measurement, effectiveness and accountability in a strategic and comprehensive manner.
Estimation of Discount Rates in Latin America: empirical evidence and challenges

Published: September 2021

This paper compares the main proposals that have been made in order to estimate discount rates in emerging markets. Seven methods are used to estimate the cost of equity capital in the case of global well-diversified investors; two methods are used to estimate it in the case of imperfectly diversified local institutional investors; and one method is used to estimate the required return in the case of non-diversified entrepreneurs. Using the first nine methods, one estimates the costs of equity for all economic sectors in six Latin American emerging markets. Consistently with studies applied to other regions, a great deal of disparity is observed between the discount rates obtained across the different models, which implies that no model is better than the others. Likewise, the paper shows that Latin American markets are in a process of becoming more integrated with the world market because discount rates have decreased consistently during the first five-year period of the XXI Century. Finally, one identifies several challenges that have to be tackled to estimate discount rates and valuate investment opportunities in emerging markets.
Falibilidad del método rough set en la conformación de modelos índice de riesgo dinámico en la predicción del fracaso empresarial

Published: September 2021

Bankruptcy is one of the most important entrepreneurial problems studied by the Financial Theory. Despite this great effort, there is not a significant progress in order to predict the economic failure. In this way, the evidence suggests that this problem, related to the experimental design, is still present because of two main reasons: ignorance about bankruptcy process and the use of the accounting information as the unique input to construct the predictive models. In order to solve those problems, the RPV Model included both qualitative and accounting information with excellent results. So, the Earning Power Theory –upon which the RPV is based– could cause problems of specification and structure in the model. Empirical results not only verify those suspicions, but they made a stronger model possible by introducing to the equation ERC values adjusted to the risk.

Insufficient institutional credit is a major contributor to the persistent poor performance of the Nigerian agricultural sector. To encourage financial institutions to increase lending to the sector, a partial credit guarantee scheme was instituted. The scheme commenced operations in 1978 with an authorized capital of N 100.00 million, subscribed to 60% and 40% by the Federal Government of Nigeria and the Central Bank of Nigeria, respectively. This paper presents an appraisal of the scheme. The results revealed that there has been continuous growth in paid-up share capital, total fund resources, maximum amount of loan obtainable by farmers, number and value of loans guaranteed, volume and value of loans fully repaid and volume and value of default claims settled. There was a long-run convergence between the number and volume of guaranteed loans and the agricultural GDP. This finding indicates the need to expand the quantum of funds available for guaranteeing agricultural loans to increase performance of the agricultural sector in the long run. This step is justified by the strategic role of agriculture in the Nigerian economy in terms of food and fiber production, job creation, income generation, poverty reduction and economic stability.

Published: September 2021

In this study we attempt to investigate the linkages between value-based performance measurements and risk-return trade off in a way to explain cross sectional asset returns. On the side of value based performance measurements, three groups of variables are used as a sorting factor: traditional measures which consist of accounting based and market based; recently popularized measures such as Economic Value Added and Market Value Added and theoretically sound measures such as foreign investor allocation and firm systematic risk indicators. The goals of the study are (i) to show how value based measurements techniques relate to risk return trade off and (ii) how these measures affect the cross sectional asset returns in manufacturing industry. Empirical results indicate that foreign investor allocation as a sorting factor produces much more meaningful risk return positive linear relation for cross sectional asset returns than traditional and recently popularized measures.
Poetic Voice in the Research: A Social Sciences Exploration in Verse
Authors: DeHart Jason
Published: September 2021

This article doubles down on the notion of poetry as a vehicle for expression in qualitative research. Following from the work of Cahnmann (2003), Stenhouse (2014), and Lahman et al. (2010), and drawing from additional inspiration including Clandinin and Connelly (2000) and Kuhn (2012), the author constructs the argument for poetic voice in research in the form of a series of poetic interplay with research concepts. The article makes the case that rich sources of data may be found in alternative representations of findings, and research questions and the people who are invited to research projects should influence researchers' choices and data collection and presentation.

Concrete becomes an important part in the process of infrastructure development. For the concrete mixture, gravel is the most important part for concrete constituents. The limitation of gravel in nature led to the creation of various studies to replacement solutions for the use of gracel in concrete mixtures.Candlenut shell is one of the waste is not getting attention in its uses. Department of Plantation North Sumatera Province recorded the candlenut production in North Sumatera in 2019 reached 13,529.40 tons. The study aims for replace some of the gravel in the concrete mixture by using a candle nut shell. The variety of concrete mixture with candle nut is 10%, 20% and 30%. Testing was conducted on concrete ages 7 days, 14 days, 21 days and 28 days aimed at finding the difference between normal concrete compressive strength without additional candlenut shells and concrete with additional candlenut shells. The result shows that there was a decrease in the values of concrete compressive strength for each group of test objects. The decrease is due to the candlenut shell having higher and water absorption compared to gravel.

La pérdida prematura de molares primarios predispone a maloclusiones incluyendo apiñamiento, impactación de dientes permanentes y alteración de la relación molar y canina. El objetivo del presente estudio es determinar el efecto de las pérdidas prematuras de molares primarios sobre la relación incisiva horizontal. El estudio es documental, retrospectivo y observacional. Se evaluaron los registros ortodóncicos (historias clínicas, fotografías y radiografías) de 209 pacientes con edades entre 4 a 15 años. La relación incisiva horizontal se consideró normal (grupo 1) cuando hubo contacto entre en borde incisal del incisivo inferior con la cara palatina del superior, aumentada (grupo 2) cuando había distancia positiva entre ellos y negativa (grupo 3) cuando los bordes incisales se encontraban a tope o en mordida cruzada. Los datos se analizaron utilizando coeficiente Pearson (p?0,001). El 22% (45 pacientes) presentó pérdidas prematuras. La prevalencia de pérdidas prematuras no tuvo diferencia significativa entre géneros y fue mayor en el grupo de 7 a 9 años. De los pacientes con pérdidas prematuras, 6 (13,3%) se clasificó en el grupo 1; 12 (26,7%) en el grupo 2 y 27 (60%) en el grupo 3. Hubo asociación positiva entre el número de molares perdidos y la presencia de mordida cruzada anterior, siendo la media de molares perdidos mayor (4, 7) en el grupo 3. Se demostró que las pérdidas prematuras de molares primarios tienen una relación estadísticamente significativa con la mordida cruzada anterior, siendo posible que la falta de soporte oclusal posterior favorezca el desplazamiento protrusivo de la mandíbula.

Published: September 2021

El objetivo del presente estudio fue realizar una revisión sistemática de la literatura sobre la evaluación de riesgo en caries de Ia infancia temprana (CIT). Para ello fueron localizados por búsqueda electrónica treinta artículos científicos originales que cumplieron con los criterios de inclusión definidos. Los mismos fueron leídos de forma minuciosa para primero ser clasificados en aquellos que cumplen con aspectos básicos del método científico, y aquellos que no; luego, se identificaron en ellos indicadores y factores de riesgo puestos a prueba para verificar su asociación con la enfermedad en cuestión, a su vez, estos fueron clasificados sucesivamente en estadísticamente significativos o no; en aquellos con y sin coherencia en la literatura consultada y en provenientes de estudios longitudinales y transversales. También se determinó el número de estudios incluidos que contemplaron lesiones cavitadas y no cavitadas en la medición de la prevalencia o incidencia de la enfermedad.
Resultados: Un total de 103 factores e indicadores de riesgo fueron identificados, de los cuales, solo ocho provienen de los seis estudios correctos en cuanto a los aspectos básicos del método científico establecidos, y se mostraron acordes a los criterios utilizados para determinar su valor relativo como evidencia científica en el proceso de clasificación. 62% de los artículos incluidos contemplaron lesiones cavitadas y no cavitadas. Conclusión: Los indicadores y factores de riesgo que se ajustaron a los criterios establecidos en relación a los padres o encargados son: Historial de Caries; motivo de consulta con el Odontólogo: Necesidad de tratamiento; creencia fatalista sobre salud oral y actitud poco favorable con respecto a la prevención; En tanto que los relacionados a los niños son: Peso del niño/a elevado para la edad; Consumo elevado de bebida carbonatada; A mayor edad; Frecuentar guarderías públicas.

Es muy grato cuando vemos que el esfuerzo desinteresado y el trabajo en equipo de tantos odontopediatras a lo largo del tiempo se vé reflejado en miles de grandes resultados. En 1971 cuando se decidió crear ALOP después de un congreso en Lima, Perú y desde 2004 cuando en Cochabamba, Bolivia un grupo de odontopediatras decidimos empezar a renovar ALOP pasando de un congreso cada dos años donde se reunían unos cuantos amigos a aprender y compartir grandes momentos, a desarrollar hoy una gran Asociación totalmente incluyente sin ningún ánimo de lucro ni económico ni personal ni profesional para nadie, a desarrollar una Asociación que solo busca el mayor un compromiso profesional y social con todos los que trabajamos por la sonrisa de nuestros niños latinoamericanos. Esta es la primera vez que logramos que una Asociación Científica de este tamaño, ya que integramos a todas las sociedades de odontopediatría de toda Latinoamérica, logre ser totalmente independiente, auto gestionable y sin ningún tipo de conflicto de intereses con ninguna compañía del mercado. Esto nos permite poder crecer y trabajar desde un punto de vista totalmente neutral hoy y hacia el futuro para solo buscar el beneficio de todos sin interés a cambio.

Com relação ao tema Big Data, observa-se atualmente uma quantidade significativa e um aumento considerável de publicações relacionadas ao assunto, porém ainda os pesquisadores sentem falta de meios para auxiliar na escolha dos referenciais teóricos. Desta forma, o objetivo deste trabalho é demonstrar um processo utilizado para a seleção das publicações relevantes, as quais são o produto de uma revisão sistemática da literatura e que buscam nortear os pesquisadores, agregando conhecimento para conduzir uma pesquisa sobre os métodos analíticos aplicados em Big Data, em ambientes de Manufaturas Inteligentes e apoiadas por abordagens multivariadas. Para buscar esse objetivo foi desenvolvido um roteiro de pesquisa e uma técnica de classificação das publicações mais relevantes. Como principais resultados deste processo, foi possível identificar 14 publicações aderentes, e que permitiram integrar os conceitos sobre Big Data, Indústria 4.0 e abordagens multivariadas, além de demonstrar a análise preditiva de dados como uma dos modelos mais utilizados na análise de Big Data.

En la búsqueda por el desenvolvimiento sustentable, la metodología Green Metric fue creada por la Universitas Indonesia, con el intuito de evaluar las acciones sustentables realizadas por universidades del mondo todo. Esta metodología evalúa criterios como infraestructura, energía y cambios climáticos, agua, gestión de residuos, sistema de transportes y educación. Fundamentados en este contexto, el presente trabajo tiene como objetivo proponer mejoría para la gestión de los residuos sólidos orgánicos en un Restaurante Universitario (RU), con base en los criterios e indicadores propuestos pela metodología Green Metric, visto que hay una producción diaria considerable de residuos en este establecimiento, y con el uso de técnicas como la compostaje, ellos pueden ser transformados en abono orgánico, proporcionando un grande gano ambiental con la disminución del volumen de residuos que son enviados diariamente para los aterros sanitarios. Se analizaron los compostadores portables disponibles en el mercado y posteriormente se realizó un estudio de viabilidad de la implantación de un compostador automático, capaz de transformar los residuos orgánicos en abono en apenas 24 horas. En acuerdo con los métodos cuantitativos de evaluación de investimentos utilizados, el estudio se mostró viable para los dos escenarios analizados.
