Algebra Thinking Process on Vocational School Students in Completing Line Problems
Authors: NU Astutik Talun
Published: October 2020

This research is motivated by the observations of researchers when teaching, it was found that there are still many students who experience obstacles when solving row problems. This type of research is qualitative research with descriptive research type. The approach and type of study were chosen according to the researcher's goal which is to describe the students' algebraic thought processes in solving the problem of ranks. The findings in this study, namely high ability students can go through each stage of problem-solving as well as doing the algebraic thinking process well, while moderate and low ability students still often ignore the stage of looking back. They also still have difficulty doing the algebraic thought process. The algebraic thinking process of high-ability students is more complex than students of medium and low ability. Highly capable students experience the process of gathering ideas, clarifying ideas, evaluating ideas, and making decisions over and over again in the thought process he does in solving problems. Besides that, in the process of thinking, high-ability students also observe patterns, make generalizations, use meaningful symbols, use functions, and make mathematical models.
Work, Unity, and Aesthetic Plenitude in La Peste by Albert Camus
Authors: Sánchez-Palencia Carmen Romero
Published: October 2020

Albert Camus, and his work, is the perfect example of achievement through personal growth, with a unitary conception of the individual and their relationship with the world and with others. In confronting the immediate, the author offers repose; in the face of the absurd, revolt, and in the face of a meaninglessness he proposes love. His task is advance, our advance, climbing a long ladder that we may also descend, although transformed, no longer as we were the first time. This project will analyse the book La Peste / The Plague, relating it and the ideas here expressed with the concept of work. Work being understood as something beyond mere occupation, or way of making a living, but the endeavours of the subject as an essential component of life. This becomes evident when one seeks to grow fully, in harmony with humanity as embodied by Camus’ characters in a situation of collective emergency, in a city in the grip of the plague. The result is a hymn of hope, of momentary triumph not without repeated stumbles, recalling again and again what we are and what we can become. Just as in our own lives, the nebulous is the constant companion of victory, which is never entirely complete.
A Feminist Stylistic Analysis of Doris Lessing's The Fifth Child (1988)
Authors: Rahimnouri Zahra , Ghandehariun Azra
Published: October 2020

This study is a feminist stylistic analysis of The Fifth Child (1988). This study attempts to combine literary and linguistic theories by using the feminist stylistic approach of feminist stylisticians. This study investigates the lexico-semantic items in narration, gendered sentences, and items such as metaphors, adjectives, and their frequency, grammar, and different lexical items such as those related to colors. Also, Short's ideas about powerful/ powerless were used to discuss the dynamic of power in the relationship between Harriet and David. Through this analysis, female ideologies of the novel were also analyzed and discussed. Feminist stylistic theories were applied to explain how Harriet's language and description represent her passivity, obedience, and dependence. This study evaluates the grammatical and lexical components of the 'female sentence' to discover that female writing is unique and different from male writing. We inferred the author’s feminist style through how Harriet is described as a traditional, old-fashioned, powerless, and subordinated woman. Harriet accepts the dominance of men and persuades readers to sympathize Harriet whom everyone blames for giving birth to an abnormal child who causes too much trouble for everyone.

The Hardness Analysis of Epoxy Composite Reinforced with Glass Fiber Compared to Nettle Fibers
Authors: Suryawan I Gede Putu Agus , Suardana NPG , Winaya IN Suprapta , Suyasa IWB
Published: October 2020

The purpose of this study is to compare the hardness of glass fiber reinforced composite materials with the hardness of netted fiber-reinforced composite materials. Glass fiber is a commercial fiber that has been used in various industries while nettle fiber is a natural fiber that is more environmentally friendly. Composite material has several advantages, namely the form that can be adjusted, high strength, lightweight and resistant to corrosion. Nettle plants are plants that have strong fibers in the bark. In this study, nettle composites were made with variations in the weight fractions of 10%, 15%, and 20%. Hardness testing used the Shore D Durometer. The results of the hardness value of glass fiber composites with weight fractions of 10%, 15%, and 20% are 82.4 Shore D, 84.5 Shore D, and 86.5 Shore D, show an increase in stable hardness because the glass fiber factor is already commercial, the fiber strength is evenly distributed. The hardness values of nettle fiber composites with fractions of 10%, 15%, and 20% are 81.6 Shore D, 85 Shore D, and 86.6 Shore D, the hardness value of each nettle composite increases with the addition of fiber weight fraction but is unstable due to the strength factor of each nettle single fiber uneven. Furthermore, with the right treatment, nettle fiber can replace glass fiber.

Authors: Prasetio Tio , Irawan Sonny , Oetomo R. Hari Kariadi
Published: October 2020

Drilling is a costly activity with high risk. Time is a key variable to minimize costs and risks and increase the overall efficiency of drilling activities. An important factor related to the drilling time is the rate of penetration (ROP). The rate of penetration varies widely and is influenced by many factors. In this research, the correlation is derived using Artificial Neural Network (ANN) Model to predict the penetration rate by considering 11 parameters including formation conditions, drilling bit, drilling fluid, and drilling operations to validate the penetration rate data that are obtained from the surrounding wells. Determination of the neural network structure is carried out to obtain the best ANN model. This model produces an equation that can predict the penetration rate of the 'T' field with an error percentage of ± 20%. The existing model is used to optimize the next well drilling activity. Data processing using the ANN method which is relatively fast and precise shows that the application of this method is interesting to discuss and develop.
La economía rural en Chile: entre la pobreza y el desarrollo
Authors: Oyarzun Méndez Edgardo Guillermo , Miranda Escolar Belén
Published: October 2020

El trabajo ofrece la visión de la economía rural chilena. Una realidad dicotómica que se mueve entre un medio rural diversificado (turismo, frutales, madera, pesca y vino, fundamentalmente), innovador, que exporta, dominado por empresas transnacionales, y la pequeña agricultura campesina, que se asocia con elevados índices de pobreza y que, en estos momentos, se encuentra ante un futuro incierto. Es hacia este sector de la población rural hacia donde deben dirigirse determinadas políticas de desarrollo encaminadas a lograr la reducción de la pobreza.

Authors: Moyano Pesquera Pedro Benito
Published: October 2020

En enero de 2008 entró en vigor la Ley para el desarrollo sostenible del medio rural. Con el objetivo de fomentar la actividad económica en estas áreas, propone que el sistema nacional de incentivos regionales dé un trato preferente a las zonas rurales consideradas prioritarias. En junio de 2010 se aprueba el Programa de Desarrollo Rural Sostenible para el periodo 2010-2014 y con él, los incentivos regionales adquieren el papel protagonista como instrumento al servicio del desarrollo rural.Este artículo tiene por finalidad contrastar si los incentivos regionales concedidos entre 2008 y 2010 muestran algún tipo de discriminación positiva a favor de las zonas rurales, en general, y de las menos desarrolladas en particular. Es decir, si han comenzado a adaptarse al nuevo escenario en el que deberán representar su papel de manera efectiva desde 2010.

Published: October 2020

Con la aprobación del Reglamento (CE) 1698/2005 del Consejo de la Unión Europea (UE) de 20 de septiembre de 2005 se puso en marcha el cuarto programa de ayuda al desarrollo rural para el período 2007-2013. Son varias las regiones españolas afectadas por este reglamento, entre ellas Andalucía. En este artículo, se expone de manera sintética el enfoque metodológico utilizado para la Nueva Estrategia Rural para Andalucía (NERA) del gobierno de la comunidad y con mayor amplitud la aplicación del Análisis Estructural de Prospectiva (AEP). El AEP es un método idóneo para analizar la complejidad de elementos, factores e interacciones presentes en los territorios rurales, así como para entender las variables en su situación presente y futura. Para ver la bondad de esta metodología se presentan los resultados obtenidos una vez aplicada a la comarca de Jerez. Finalmente se concluye el análisis con la discusión de los resultados y el análisis de las fortalezas y debilidades de la metodología aplicada.
El riesgo de disponibilidad de agua en la agricultura: una aplicación a las cuencas del Guadalquivir y del Segura
Authors: Pérez Blanco Carlos Dionisio , Gómez Gómez Carlos Mario , Del Villar García Alberto
Published: October 2020

La agricultura es un sector clave en la economía rural y constituye un motor de crecimiento en regiones del sur de España capaces de desarrollar un regadío competitivo de alto rendimiento. Este es el caso de determinadas comarcas de la Cuenca del Guadalquivir y del Segura, que no obstante afrontan los problemas derivados de la escasez creciente de agua y de un riesgo de sequía cada vez más acusado. Para responder más efectivamente a estos problemas, se han aprobado recientemente una serie de Planes de Sequía que pretenden ofrecer una respuesta planeada y anticipada que sustituya a la gestión de emergencias del pasado. En este trabajo se estudia el impacto previsible de las reglas de decisión de dichos Planes de Sequía (aprobados sin ningún estudio previo sobre las repercusiones económicas de su aplicación), con el objetivo de evaluar si estos contribuyen o no a la sostenibilidad del regadío y por lo tanto de la economía rural y regional que se sustenta sobre esta actividad económica. Se desarrolla un modelo estocástico para evaluar las pérdidas económicas derivadas de la aplicación de los Planes de Sequía en el sector agrario, concluyendo que tales planes no suponen un avance en la sostenibilidad del regadío ni en la garantía de suministro para usos prioritarios.

Authors: Coetzee Melinde , Schreuder AMG (Dries) , Clinton-Baker Michelle
Published: October 2020

The study explored the link between the career anchors, organisational commitment and turnover intention of a sample of individuals employed in the South African retail sector. A non-probability purposive sample (N = 343) of employees from an organisation in the South African retail sector was utilised. The participants were represented by predominantly women (72%) and black people (94%) between the ages of 25 and 45 years (80%). Following a cross-sectional quantitative research approach, correlational and stepwise regression analysis was performed to achieve the objective of the study. The results showed that the entrepreneurial creativity-anchored individuals were likely to have low organisational commitment and high turnover intention, while the lifestyle-anchored individuals had high levels of organisational commitment and high turnover intention. The dominant affective/normative commitment profile of the sample of participants significantly predicted low turnover intention. The findings of the study and practical implications provide useful information to managers interested in retaining staff in the retail sector.
Staff perceptions on talent management and retention: A case of a labour organisation in Gauteng
Authors: Strydom Nadia , Schultz Cecile , Bezuidenhout Adele
Published: October 2020

As high turnover is costly and disruptive, all organisations aim to retain talented employees. Talented employees give organisations a competitive advantage in the complex business environment of today. The aim of this article is to report on the employeesâ€™ perceptions of talent management retention at a labour organisation in Gauteng. The population comprised 317 permanent staff members, and a convenience sample of 162 was used. A principal factor analysis was employed to determine the main factors, namely, dedication to staff and dedication of staff. Descriptive statistics were used to determine the perceptions of staff members on these two factors. In conclusion, recommendations are offered to labour relations practitioners on how human resource practices can contribute to the fair treatment and retention of talented employees in an organisation.
Return-to-work experiences of female employees following maternity leave
Authors: Brand Heinrich , Barreiro-Lucas Judite
Published: October 2020

Corporate culture seemingly does not encourage talented women to return to the workplace or continue to operate effectively in the workplace, while managing their domestic responsibilities. This has a direct influence on the progression of talented women to senior positions and their retention in those positions (Baggallay 2011).While the above statement may be a narrow view, considering shifts in many companies' policies which aim to support work-family balance, there are still many underlying concerns regarding working mothers.The primary purpose of this study is to identify common themes arising from the return-to-work experiences of female employees following maternity leave in South Africa.The results of this study revealed that despite viewing work positively, the participants in the study found the return-to-work experience after childbirth difficult. A significant change in the attitudes of the participants towards their careers after childbirth was also identified. This change is not necessarily negative and should not be interpreted as an indication of loss of interest by the employees in their careers. It does, however, highlight the need for adequate management of the whole process from â€œworkplace pregnancyâ€ to return to work of female employees.Employers open to the evolution of best practice for maternity leave will attract and retain high-calibre female talent.
Molybdenum Trioxide on Anatase TiO2(101) - Formation of Monodispersed (MoO3)1 Monomers from Oligomeric (MoO3)n Clusters

Published: October 2020

Complex oxide systems with hierarchical order are of critical importance in material science and catalysis. Despite their immense potential, their design and synthesis are rather difficult. In this study we demonstrate how the deposition of small oligomeric (MoO3)1-6 clusters, which can be formed by the sublimation of MoO3 powders, leads to the formation of locally ordered layers of (MoO3)1 monomers on anatase TiO2(101). Using both high-resolution imaging and theoretical calculations, we show that at room temperature, such oligomers undergo spontaneous dissociation to their monomeric units. In initial stages of the deposition, this is reflected by the observation of one to six neighboring (MoO3)1 monomers that parallel the size distribution of the oligomers. A transient mobility of such oligomers on both bare TiO2(101) and (MoO3)1 covered areas is key to the formation of a complete layer with a saturation coverage of one (MoO3)1 per two undercoordinated surface Ti sites. We further show that such layers are stable to 500 K, making them highly suitable for a broad range of applications.
Evaluating the Benefits of Kinetic Monte Carlo and Microkinetic Modeling for Catalyst Design Studies in the Presence of Lateral Interactions
Authors: Li Xiao , Grabow Lars
Published: October 2020

Popular computational catalyst design strategies rely on the identification of reactivity descriptors, which can be used along with Brønsted−Evans−Polanyi (BEP) and scaling relations as input to a microkinetic model (MKM) to make predictions for activity or selectivity trends. The main benefit of this approach is related to the inherent dimensionality reduction of the large material space to just a few catalyst descriptors. Conversely, it is well documented that a small set of descriptors is insufficient to capture the intricacies and complexities of a real catalytic system. The inclusion of coverage effects through lateral adsorbate-adsorbate interactions can narrow the gap between simplified descriptor predictions and real systems, but mean-field MKMs cannot properly account for local coverage effects. This shortcoming of the mean-field approximation can be rectified by switching to a lattice-based kinetic Monte Carlo (kMC) method using cluster expansion representation of adsorbate−adsorbate lateral interactions.

Using the prototypical CO oxidation reaction as an example, we critically evaluate the benefits of kMC over MKM in terms of trend prediction accuracy and computational cost. After confirming that in the absence of lateral interactions the kMC and MKM approaches yield identical trends and mechanistic information, we observed substantial differences between the two kinetic models when lateral interactions were introduced. The difference, however, is mainly manifested in the absolute rates, surface coverages and the optimal descriptor values, whereas relative activity trends remain largely intact. Moreover, the nature of the rate-determining step as identified using Campbell’s degree of rate control is also consistent between both approaches. Considering that the computational cost of MKM is ca. three orders of magnitude lower than for a kMC simulation, the MKM approach does provide the best balance between accuracy and efficiency when used in the context of computational catalyst screening.
Data-Driven Many-Body Models with Chemical Accuracy for CH4/H2O Mixtures
Authors: Riera Marc , Hirales Alan , Ghosh Raja , Lab Paesani
Published: October 2020

Many-body potential energy functions (PEFs) based on the TTM-nrg and MB-nrg theoretical/computational frameworks are developed from coupled cluster reference data for neat methane and mixed methane/water systems. It is shown that that the MB-nrg PEFs achieve subchemical accuracy in the representation of individual many-body effects in small clusters and enables predictive simulations from the gas to the liquid phase. Analysis of structural properties calculated from molecular dynamics simulations of liquid methane and methane/water mixtures using both TTM-nrg and MB-nrg PEFs indicates that, while accounting for polarization effects is important for a correct description of many-body interactions in the liquid phase, an accurate representation of short-range interactions, as provided by the MB-nrg PEFs, is necessary for a quantitative description of the local solvation structure in liquid mixtures.
Comment on “Boosted Molecular Mobility During Common Chemical Reactions"
Authors: Günther Jan-Philipp , Fillbrook Lucy , MacDonald Thomas , Majer Günter , Price William S. , Fischer Peer , Beves Jonathon
Published: October 2020

The apparent “boosted mobility” observed by nuclear magnetic resonance (NMR) diffusion measurements is the result of a known artefact. When signal intensities are changing during an NMR diffusion measurement for reasons other than diffusion, the use of monotonically increasing gradient amplitudes produces erroneous diffusion coefficient values. We show that no boosted molecular mobility is observed when shuffled gradient amplitudes are applied.

The synthesis and characterization of Fe2(CO)5(L){μ-(SCH2)2}SnMe2 (L = PPh3 (2) and P(OMe)3 (3) derived from the parent hexacarbonyl complex Fe2(CO)6{μ-(SCH2)2}SnMe2 (1) is reported. Whereas 1 exhibits a unique planar structure, X-ray crystallography showed that the apical orientation of L in complexes 2 and 3 results in a chair/boat conformation of the Fe2S2C2Sn fused six-membered rings, which is typical for diiron dithiolato complexes. In solution, NMR and FTIR spectroscopic techniques provide evidence for a dynamic process of apical-basal site exchange of the ligand L in 2 and 3. Protonation experiments on 2 and 3 in MeCN using CF3CO2H, HCl or HBF4·Et2O suggest enhanced protophilicity of the Fe-Fe bond due to the presence of the electron donor ligands L as well as the stannylation effect. While the carbonyl ligands in 2 stretch at lower wavenumbers ν(CO) than those in 3, the cyclic voltammetric reduction of 2 unpredictably occurs at less negative potential than that of 3. In contrast to 1, the presence of PPh3 and P(OMe)3 in 2 and 3, respectively, allows protonation prior to reduction as shown by FTIR spectroscopy and cyclic voltammetry.

Published: October 2020

Although hematopoietic prostaglandin D synthase (H-PGDS) is an attractive target for treatment of a variety of diseases, including allergic diseases and Duchenne muscular dystrophy, no H-PGDS inhibitors have yet been approved for treatment of these diseases. Therefore, the development of novel agents having other mode of actions to modulate the activity of H-PGDS is required. In this study, a chimeric small molecule that degrades H-PGDS via the ubiquitin-proteasome system, PROTAC(H-PGDS)-1, was developed. PROTAC(H-PGDS)-1 is composed of two ligands, TFC-007 (that binds to H-PGDS) and pomalidomide (that binds to cereblon). PROTAC(H-PGDS)-1 showed potent activity in the degradation of H-PGDS protein via the ubiquitin-proteasome system and in the suppression of prostaglandin D2 (PGD2) production. Notably, PROTAC(H-PGDS)-1 was slightly more effective in the suppression of PGD2 production than the known inhibitor, TFC-007. Thus, the H-PGDS degrader—PROTAC(H-PGDS)-1—is expected to be useful in biological research and clinical therapies.

Published: October 2020

The synthesis of new graphene-type materials (via polymerization of porphyrin macrocycles) through a simple chemical synthetic pathway (at RT) has been demonstrated. This newly synthesized material can be dispersed in water with an average sheet size of few microns and with single layer thickness. As the porphyrin contains four inner ring nitrogen atoms thus the presented polymeric material will be close analogous of N-doped graphene. Porphyrin as the key component to synthesize layered graphene type continuous 2D structure has never been attempted before.
Hierarchy of π-Stacking Determines the Conformational Preference of Bis-Squaraines
Authors: Singh Abhishek , Singh Reman K. , Patwari G Naresh
Published: October 2020

The rational design of conformationally controlled foldable modules can lead to a deeper insight into the conformational space of complex biological molecules where non-covalent interactions such as hydrogen bonding and π-stacking are known to play a pivotal role. Squaramides are known to have excellent hydrogen bonding capabilities and hence, are ideal molecules for designing foldable modules that can mimic the secondary structures of bio-molecules. The π-stacking induced folding of bis-squaraines tethered using aliphatic primary and secondary-diamine linkers of varying length is explored with a simple strategy of invoking small perturbations involving the length linkers and degree of substitution. Solution phase NMR investigations in combination with molecular dynamics simulations suggest that bis-squaraines predominantly exist as extended conformations. Structures elucidated by X-ray crystallography confirmed a variety of folded and extended secondary conformations including hairpin turns and 𝛽-sheets which are determined by the hierarchy of π-stacking relative to N–H···O hydrogen bonds.

Occurrence of indicator bacteria and pathogens in the waters of the noyyal river near its source and downstream in coimbatore district
Authors: P Zion Meshach , G. Sargunar Clara
Published: October 2020

Water, the bloodstream of the biosphere, also acts as a sink, solvent and transport vehicle for domestic, agricultural and industrial waste, causing pollution. The Noyyal River, a tributary of the River Cauvery, was once the lifeline of Coimbatore, but is now being threatened by pollution from various sources. Assessments of microbiological water quality have focused on the presence of Fecal Indicator Bacteria, which indicate that a contamination pathway exists between a bacterial source and the water supply, serving as a route for pathogen entry. Water samples from seven sites (Kooduthurai, Madakkadu,Thombilipalayam, Alandurai, Mathampatti, Perur and Aathuppalam) along the Noyyal, were analyzed for various microbiological characteristics. The results indicated that the river was relatively unpolluted upstream near its sources, but is progressively polluted on moving further downstream towardsCoimbatore city. Levels of Total Heterotrophic Bacteria, indicators such as Enterobacteriaceae, Total Coliforms, Fecal Coliforms (FC), Fecal Streptococci (FS), pathogens like Salmonella sp., Shigella sp., and Vibrio sp. were elevated at downstream sampling sites. Evaluation of the FC:FS ratio revealed that, the water was unfit for drinking at almost all the downstream sampling stations, and could have limited use for irrigation. The release of fecal microorganisms and pathogens from the sediments to the water column could be a major source of bacterial loading. Non-point sources were identified as the major contributors of contaminants. Regular monitoring of the river water and sediment, amelioration of point / non-pointsources of pollution, and speedy implementation of remedial measures, may restore this stretch of the Noyyal River to its former pristine state.

This article presents software tools designed for construction of heterogeneous models by software integration of logical models having their work methods set in the knowledge bases and engineering models created in a technical simulation environment. In order to build logical models we use our software «Software-and-mathematical model of the command-andmeasurement system’s onboard equipment». Engineering models are built in the graphical programming environment of the LabVIEW. The software functions are described for creation of graphical schemes of models, data structures and telemetry data packages design, creation of the command base and setting of the methods of the model’s elements work in the knowledge bases’ rules. We provide an example of a heterogeneous model simulating the logics of the spacecraft’s command-and-measurement system’s onboard equipment operation including the library of virtual devices for the receiving and transmitting path simulation and the knowledge base with the rules of the onboard system’s interaction during reception, transmission, execution and confirmation of commands. This example demonstrates the points of integration of logical simulators and virtual devices. The model allows to assess the parameters of the receiving and transmitting path and the influence of destabling factors on communication line’s quality, simulate generation and transformation of the signal coming from the source of information – ground segment – to the onboard equipment and simulate logical interaction of the systems if the necessary signal level is provided. Each element of the model can be transformed and processed by the subject area’s specialist depending on the specifics of the solved tasks.

Published: October 2020

Within the framework of the conventional Nikiforov-Uvarov method and a new form of Greene-Aldrich approximation scheme, we solved the Schrödinger equation with the energy-dependent screened Coulomb potential. Energy eigenvalues and energy eigenfunctions were obtained both approximately and numerically at different dimensions. The energy variations with different potential parameters, quantum numbers and energy slope parameter, respectively were also discussed graphically. The major finding of this research is the effect of the energy slope parameter on the energy spectra, which is seen in the existence of two simultaneous energy values for a particular quantum state. Our special cases also agree with the results obtained from literature, when the energy slope parameter is zero.
POBREZA AGRARIA Y SHOCK DE INGRESOS EN PUNO: UN ANÁLISIS EN BASE A LA ENAHO
Authors: Zegarra Mendez Eduardo
Published: October 2020

En este artículo se analiza la evolución de la pobreza monetaria en las unidades de agricultura familiar en Puno para el periodo 2007 al 2015 en base a datos de la ENAHO.  La importante reducción de pobreza en la región entre 2007 y 2012 empieza a detenerse en 2013, y entre 2014 y 2015 se observa por primera vez un aumento en la tasa de pobreza general y en la de los hogares agropecuarios. Dada la forma que toma este incremento de pobreza, planteamos que se habría originado en un shock negativo de ingresos en las zonas urbanas afectadas por la desaceleración económica, el cual ha tenido efectos adversos en los ingresos agropecuarios, especialmente de los más articulados al mercado. Adicionalmente, generamos una estimación tipo Probit para analizar el perfil de pobreza de los hogares agropecuarios de Puno de acuerdo a características como rango de edad y tamaño, lengua materna, género y educación del jefe de hogar, entre otras variables.  El análisis sugiere algunos temas a incorporar a la agenda de políticas para reducir de manera más efectiva y sostenible la pobreza en el campo de Puno en los próximos años.

Authors: Chura Zea Efrain Franco
Published: October 2020

El objetivo del estudio es estimar el impacto del proyecto “Desarrollo de capacidades y generación de empleo en la región noreste de Puno, período 2010-2012” en el ingreso de las familias beneficiarias. El ámbito del estudio corresponde a unidades familiares alpaqueras de los distritos de Cojata, Ananea y Patambuco cuya población total beneficiaria fue de 582 familias; La metodología de análisis utilizada se basó en el método de emparejamiento de la probabilidad de participación (Propénsity Score Matching) y la variante del Nearest Neighbour Matching para ello se usó indicadores sociales, económicos, productivos y reproductivos. Los resultados señalan que el efecto promedio en el ingreso de las familias intervinientes en el proyecto en comparación con el grupo de control resultó S/. 580.00. Las variables: distrito, sexo, estado civil, hectáreas y piel de alpacas crías contribuyen significativamente al balance y emparejamiento de los datos en 7 bloques, mientras que las variables edad, número de hijos y alpacas reducen las probabilidades de emparejamiento. La no significancia de la variable alpacas explicaría la naturaleza del proyecto como intervención no sólo con resultados en el corto plazo sino más bien que el mejoramiento de la calidad en alpacas se da en el mediano y largo plazo.

Authors: Velásquez Alanoca Yosi Miguel
Published: October 2020

El objetivo del presente estudio es estimar el impacto del programa JUNTOS sobre el ingreso del hogar beneficiario analizando su efecto en los distintos cuantiles de la distribución del ingreso de los hogares beneficiarios, y sobre su ingreso laboral. Para ello se utiliza la base de datos panel de la Encuesta Nacional de Hogares (ENAHO) entre los años 2013 y 2015 aplicándose técnicas para estudios con diseño cuasiexperimental como el Propensity Score Matching (PSM), la estimación con dobles diferencias (DD) y la regresión cuantílica (QR). De las estimaciones realizadas se concluye que el programa JUNTOS tuvo un impacto positivo sobre el ingreso total del hogar beneficiario, incrementando sus ingresos en 20% más que un hogar no beneficiario; además, el impacto es diferenciado para los hogares ubicados en el cuantil más bajo, quienes aumentaron sus ingresos en un 31% más que un hogar no beneficiario ubicado en el mismo cuantil, respecto al ingreso laboral se evidencia un impacto negativo, pero no significativo.

Entre los años 2000 a 2017 las exportaciones no tradicionales en el Perú han mostrado un acelerado crecimiento explicado principalmente por el sector agropecuario, seguido por los sectores pesquero, textil, químico y sidero-metalúrgico presentando un sorprendente crecimiento de 470.95% en este período. El objetivo de este trabajo es hallar los determinantes macroeconómicos de las exportaciones de productos no tradicionales para el Perú mediante la existencia de cointegración, para ello se utiliza la metodología de Johansen y la implementación del Modelo Vector de Corrección de Error para hallar la dinámica de corto y largo plazo para las exportaciones de productos no tradicionales. De los resultados se obtuvo que los determinantes de las exportaciones son la producción bruta de EEUU, índice de tipo de cambio real bilateral y el índice de exportaciones, las mismas que guardan una relación de cointegración. Finalmente, se encontró que la producción bruta de EEUU tiene una influencia positiva, el índice de tipo de cambio real bilateral una influencia negativa y el índice de precios de las exportaciones guarda una influencia negativa sobre las exportaciones de productos no tradicionales en el Perú.
