Within the rapid proliferation of gender studies and the underrepresentation of women in science, technology, engineering and mathematics (STEM), an area of research has emerged among scholars. Over the past years, different academic, health and economic institutions have called for a closer analysis of women underrepresentation in STEM careers. In Peru, there is some preliminary evidence with regard of women underrepresentation in STEM careers, however, qualitative studies are scarce in the field. To analyze this gender gap phenomenon, we explored experiences, feelings, behaviors and Social Cognitive Career Theory variables such as self-efficacy, barriers, supports and career development. To reach this goal, qualitative and in-depth interviews were carried out among female engineering students. All participants were in their last year of career andwere selected from three universities i...

The aim of this study was to determine the effect of five levels of inclusion (0, 0.1, 0.2, 0.3 and 0.4%) of a commercial premix of vitamins and trace minerals in the feed on the productive parameters of fattening guinea pigs from 3 to 6 weeks (post-weaning phase) and from 7 to 10 weeks (pre-slaughter phase). Sixty 14-day-old male guinea pigs of the Peru breed were randomly assigned to 20 pens and 5 treatments, under a completely randomized experimental design. The guinea pigs were fed ad libitum with the concentrate and with restricted green forage for eight weeks. In the post-weaning phase, the treatment with 0.1% premix achieved higher body weight, weight gain and feed conversion rate, while there were no differences between treatments in the pre-slaughter phase. The treatment with 0.4% of the premix caused a higher liver weight in the guinea pigs. It is concluded that fattening guine...

it is well known that an economy based on knowledge has a strong potential for human capital. In this sense, universities have a key role in student's professional development and performance, as well as to increase the number of professional population in science, technology, engineer, and mathematics. The aim of the present study is to obtain student's individual, structural and external characteristics by considering their context, which represents a condition that shape student's interest, persistence and goals in computing engineering discipline through career development. To accomplish this, we used self-reports based on Social Cognitive Career Theory in a sample of system engineering students (n=270) from three universities in the north of Lima. In addition to this, we evaluate the model through Structural Equation Modeling (SEM) under the partial least squared (PLS-SEM) approach....

Although the participation of women in higher education has increased, they are still underrepresented in Science, Technology, Engineering, and Mathematics (STEM) areas. Peru as other Latin-American countries, has an additional issue to cope with this reality, which is the lack of research in gender gap, recruitment, retention and promotion for women in science and technology. In 2017, a study carried out by Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica (CONCYTEC), it was found that one out of four researchers in engineering and technology were women. Moreover, official national statistics for women in higher education accounted for 15% of the total number of students enrolled in engineering careers. To address the issue of gender equality in education, several national studies have been carried out with the aim to generate relevant information and knowledge for the...

Previous research has found that first-years in college is challenging due to changes in academic demands and the adaptation process. In addition to this, research on career development has found that barriers and supports may influence career interest, motivation to continue and student retention. This study explores the influence of specific supports and barriers among first-year engineering college students. To reach this goal, a case study was conducted with 425 engineering students at three universities in Lima, Peru. Based on Social Cognitive Career Theory (SCCT), we performed a Structural Equation Model (SEM) to assess effects of contextual factors such as barriers and supports on self-efficacy, coping self-efficacy, and goals. Results showed that certain supports and barriers influence self-efficacy, cope self-efficacy and goals. Effects of these factors in first-year students an...

The aim of this work is to design, implement and validate a primary communication system based on a brain-computer interface. There are people who-for various reasons-are affected in their ability to externalize their communication, however, they receive and process information from different sources. This system would allow basic communication-allowing the user to answer closed questions-through thought. The system was implemented by analyzing and interpreting electrical signals from brain activity, collected through electrodes attached to the scalp. The analog electrical signals were received by a data acquisition system and digitized for computer analysis. We implemented different signal processing techniques, pattern analysis, and classification and discrimination methods. By analyzing these signals and interpreting the electrical patterns, was achieved understand answers to simple q...

Worldwide, chronic pain has established as one of the foremost medical issues due to its 35% of comorbidity with depression and many other psychological problems. Traditionally, self-report (VAS scale) or physicist inspection (OPI scale) perform the pain assessment; nonetheless, both methods do not usually coincide [14]. Regarding self-assessment, several patients are not able to complete it objectively, like young children or patients with limited expression abilities. The lack of objectivity in the metrics draws the main problem of the clinical analysis of pain. In response, various efforts have tried concerning the inclusion of objective metrics, among which stand out the Prkachin and Solomon Pain Intensity (PSPI) metric defined by face appearance [5]. This work presents an in-depth learning approach to pain recognition considering deep facial representations and sequence analysis. Co...

La investigación tiene como objetivo establecer la relación entre los factores sociodemográficos y la elección de la carrera de Ingeniería Civil en una Universidad de Cajamarca - Perú, 2023. El enfoque es de carácter cuantitativo, porque se basa en la recolección de información con base en un análisis estadístico. El tipo de investigación es básico de nivel correlacional, porque se estudia la relación de dos variables y cómo estas interactúan entre sí. El diseño es no experimental de corte transversal, porque se efectúa sin manipular las variables y solo se recogerá datos en un único periodo de tiempo. La población del estudio está conformada por 500 estudiantes que forman parte de la carrera de Ingeniería Civil de una universidad de Cajamarca. La muestra está constituida de 112 estudiantes seleccionados a través de un muestreo no probabilístico por convenienci...

The aim of this study was to evaluate the effect of protein supplementation at service and before delivery on the load of gastrointestinal nematodes in naturally infested dairy goats. Two groups of 17 goats were evaluated: control group (SinSu) without supplementation and supplemented (ConSu) with 19% protein during service and 45 days prepartum. The animals were monitored every 15 days during service and in the 45 days before lambing and monthly during the rest of the trial. The parasitic load (eggs per gram of feces – epg) and their differentiation into genus were determined, in addition to the hematocrit, total proteins, body condition (BCS) and clinical and Famacha grade. The weight of the offspring and milk production at 90 days were recorded. No significant differences were found in epg of the two groups before lambing, but protein supplementation resulted in a lower parasitic lo...
