El presente aporte se circunscribe a uno de los más serios problemas de la criminalística peruana, el abandono de la poroscopia, disciplina abocada al estudio de los poros presentes en la piel. Para ello, se efectuó el estudio de la literatura nacional e internacional que versa sobre la dimensión teórica de esta rama del saber y la evidencia empírica referida a su aplicación. Se concluyó que, el uso de la poroscopia optimizaría la identificación personal, al reducir varios de los equívocos provocados por el empleo aislado de los dos primeros niveles de análisis dactilar, e incrementaría la fiabilidad de las homologaciones, motivos por los que la misma debe ser implementada a nivel nacional.

Objective. Understand the perspective of patients in relation to the current way of obtaining an appointment in primary health care. Methods. A bibliography search was performed in the online databases in Spanish and English. The main source was sought by reviewing the bibliographical references of the publications. Results. It was found that the shift to virtuality has made it easier for users to access a primary health care appointment, reducing waiting time and paving the way for non-face-to-face care; the level of user satisfaction has increased positively. Conclusions. Phone and virtual requests are here to stay; these are not intended to replace face-to-face requests, but they are a necessary tool to improve the quality of care for users.

This paper is based on the premise that parole assumes the configuration of rights and the objective was to reach an approximation to the implications of such a postulate in the Peruvian legal system. For that purpose, an analysis of the national and international literature that deals with the dogmatic and applicational dimensions of these figures was carried out. It was concluded that it is not possible to restrict the legal application of early release, regardless of the seriousness of the crime or sentence imposed, and that the concession factors to be legislated must be based on empirical evidence related to recidivism.

The present research aimed to examine whether perfectionism and some demographic variables can predict levels of resilience (and their dimensions) in adults from Venezuela. The design was cross-sectional predictive, through logistic regression analysis. Participants were 313 Venezuelan mature adults (M = 46.44 years), mostly women (82.7%), residents of the interior of the country (70.9%), with higher education (64.2%), and paid employment (67.9%). An adapted version of the Multidimensional Perfectionism Scale (Frost et al., 1990) and the Resilience Scale for Adults (Hernández y Lezama, 2016) was applied via Google Forms. Organization was a positive predictor of resilience and two of its dimensions (OR = 1.13 - 1.27), while fear of mistakes was a negative predictor of resilience and “morality and values” (OR = 0.96). Personal standards positively predicted“perseverance and hope” ...

Cancer is the second leading cause of death in Latin America, and the economic cost it requires will increase markedly in future years (1). If nothing is done about it, cancer incidence and mortality in South and Central America will continue to rise sharply between 2012 and 2035 (2). It is expected that by 2030 the incidence of cancer will increase by 32%, reaching 5 million cases per year (1). At the level of Latin America, health policies have been implemented, where they prioritize the feeding of these patients to reduce the sequelae that the treatments can cause, obtaining optimal results (3). It is in this context that the effects of cancer and its treatment make it difficult to meet the nutritional requirements of patients. Chemotherapy is the most widely used medical treatment for cancer in the world. Knowing that cancer cells tend to grow and divide faster than normal cells, thi...

Pretendemos elaborar un modelo de regresión lineal múltiple para analizar la relación entre el riesgo país de Perú y un conjunto de indicadores relacionadas con la economía peruana y global. Todas estas variables macroeconómicas son registradas mensualmente por el Banco Central de Reserva del Perú. Identificamos la variable respuesta EMBIG-Perú que viene a ser el riesgo país de Perú y ocho covariables que sospechamos ser relacionadas con la respuesta e independientes entre sí. Inicialmente utilizamos el método de mínimos cuadrados ordinarios, pero puede presentar ciertas limitaciones de sesgo, de variabilidad excesiva, o una interpretabilidad deficiente. Para subsanar estas limitaciones, nos incursionamos a métodos de selección óptima de covariables, al análisis de componentes principales y también a los modelos de regresión penalizada. Adicionalmente nos valeranos de...

Most Andean lakes and lagoons are used as reservoirs to manage hydropower generation and cropland irrigation, which, in turn, alters river flow patterns through processes of storage and discharge. The Carhuacocha and Vichecocha lagoons, fed by glaciers, are important aquatic ecosystems regulated by dams. These dams increase the flow of the Mantaro River during the dry season, supporting both energy production and irrigation for croplands. Water quality in the Carhuacocha and Vichecocha lagoons was assessed between storage and discharge events by using the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) and multivariate statistical methods. The quality of both lagoons is excellent during the storage period; however, it decreases when they are discharged during the dry season. The most sensitive parameters are pH, dissolved oxygen (DO), and biochemical oxyge...
