La producción del conocimiento de las regiones competitivas: una aproximación basada en modelos de variables latentes
Authors: Caicedo-Asprilla Henry
Published: July 2020

En este documento se propone una función de producción del conocimiento, con base en la medición de variables no observables, que aporta una solución práctica a los problemas metodológicos en esta área de estudio. Al respecto, se define una función de producción de conocimiento que depende del capital humano, los gastos en investigación y desarrollo, los spillovers y el entorno innovador. La función es estimada con la técnica partial least squares path modeling, la cual permite medir el efecto de variables no observables. Se logró mostrar que estos constructos (variables latentes) son confiables y significativos; además, se concluye que esta función describe acertadamente cómo se crea y explota el conocimiento en una región.

Published: July 2020

El objetivo de este documento es estudiar la relación entre las peticiones de los movimientos sociales en el departamento del Chocó, Colombia, y las condiciones de desarrollo socioeconómico del territorio. La estrategia de investigación incluyó una revisión histórica de las peticiones de las protestas y un análisis de la evolución de los principales indicadores económicos, sociales y de finanzas públicas locales en el departamento. Los resultados indicaron que las peticiones de las protestas efectivamente coinciden con las condiciones de rezago en la región. Adicionalmente, se encontró un aumento importante en las transferencias del Gobierno nacional al departamento y a sus municipios en los últimos años, pero una baja eficiencia en el manejo de los recursos disponibles.
Personal values and gift giving act: a proposed connection
Authors: Passos Sérgio Cruz , Leite Ramon Silva , Pinto Marcelo de Rezende
Published: July 2020

The consumption of gifts is relevant and many commerce sales are carried out during traditional times of gift-giving, such as Christmas. The objective of this paper is to propose and validate a model that measures the influence of personal values in the act of gift giving, also considering the role of gender in these relationships. A survey was carried out on 1,085 consumers. Through structural equation modeling with partial least squares (SEM-PLS), it was verified that the gift giving act is influenced by five personal values: self-direction, hedonism, tradition, achievement, and power. The results show that personal values can be used to predict the behavior of gifting. This study integrates Gift-Giving Theory and Personal Values Theory to better understand consumer attitudes and behaviors.
Gobierno de la ciudadanía y gobierno de sí
Authors: Solano Victor Miguel
Published: July 2020

Este artículo buscará demostrar la vigencia del método postestructuralista para entender fenómenos contemporáneos de poder en lo urbano. Para ello el texto reúne algunas de las principales pautas de dicho campo epistemológico en relación al gobierno de la población y de las ciudades contemporáneas. Se retoman experiencias particulares de las dos alcaldías de Antanas Mockus (1995-1997 y 2001-2003) en Bogotá abarcando los discursos científicos revestidos de objetividad, las técnicas institucionales para su comprobación, y la cesión parcial de la responsabilidad de gobierno a los ciudadanos. Para analizar estas experiencias, se propone identificar la emergencia de algunos de los enunciados más importantes que permitieron la consolidación de la “cultura ciudadana” en Bogotá entre 1995 y 2003 como dispositivo de gobierno. En segunda medida, se plantea describir las tecnologías de normalización que permitieron un ejercicio de gobierno multidimensional entre los ciudadanos. Estas acciones se enmarcan en la propuesta analítica de Michel Foucault trazable en La arqueología del saber y en otros de sus textos, propuesta evaluada como posible camino teórico-metodológico para estudiar interdisciplinarmente el fenómeno de la “cultura ciudadana”.

Published: June 2020

Objectives: This study aimed to identify the relationship between antenatal depression and pregnancy outcomes, including the risk of developing postpartum depression in Oman. Methods: This follow-up prospective longitudinal cohort study included pregnant women attending primary healthcare institutions in Muscat, Oman from January to November 2014. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for antenatal and postnatal depression. Pregnant Omani women with a gestational age ≥32 weeks attending 12 local health centres for antenatal care in Muscat were invited to participate. Recruited women were followed-up at 6–8 weeks after delivery. The following pregnancy outcomes were assessed: mode of delivery (normal or Caesarean section [CS]), gestational age at delivery (preterm or fullterm), baby’s birth weight and development of postnatal depression. Results: A total of 959 women participated in this study (response rate: 97.3%). In total, 233 women (24.4%) had antenatal depression with a score of ≥13 on the EPDS. Of the 592 participants (61.7%) who attended postnatal clinics at 6–8 weeks post-delivery, 126 (21.3%) were positive for postnatal depression. Logistic multivariate regression analysis showed that antenatal depression was associated with increased risk of CS (odds ratio [OR] = 1.79; 95% confidence interval [CI]: 1.20–2.66) and postnatal depression (OR = 8.63; 95% CI: 5.56–13.39). Conclusion: Screening women for antenatal depression and providing appropriate management may reduce adverse pregnancy outcomes and the risk of developing postnatal depression.Keywords: Depression; Postnatal depression; Women Health Services; Maternal Health Services; Pregnancy; Primary Health Care; Oman.

Objectives: This study aimed to assess the perceptions of medical interns with regards to the internship training programme offered at Saudi medical schools and to explore factors influencing their overall satisfaction with this progamme. Methods: This exploratory study was conducted at four medical schools in Saudi Arabia between July 2017 and June 2018. All medical interns undergoing internship training at the selected medical schools during the 2017–2018 academic year were invited to participate in the survey. A questionnaire covering 10 internship dimensions and including a total of 76 items and one global item was designed to assess the medical interns’ satisfaction with the training programme. Results: A total of 295 interns returned completed questionnaires (response rate: 92%). Overall, the interns’ satisfaction with all 10 internship dimensions was high (mean score: ≥3.6). A multiple regression analysis indicated that various factors were significant predictors of medical interns’ overall satisfaction with the internship training programme, including orientation, training site services, supervision, relationships with their superiors and hospital activities (P <0.050 each). Conclusion: Medical interns were highly satisfied with the internship training programme offered at Saudi medical schools, with various factors found to significantly influence overall satisfaction. The findings of this study may help policymakers in Saudi Arabia to improve the internship training programme so as to ensure medical interns’ overall satisfaction and potentially improve their learning outcomes and clinical training.Keywords: Undergraduate Medical Education; Internship and Residency; Attitudes; Clinical Competence; Saudi Arabia.
The Carpal and Tarsal Bones of the Human Body: Arabic mnemonics
Authors: Joseph Mickaël A. , Natarajan Jansirani
Published: June 2020

Memorising human anatomy structures remains a challenge for nursing students. Educators endeavour to make human anatomy interesting and easy to memorise. Various instructional approaches can be used to help students enhance their memory. Mnemonics, for example, are well-established educational strategies that have proven useful in the encoding, retention and retrieval of anatomical terms. The carpal and tarsal bones are some of the anatomical structures that prove challenging to nursing students’ study of anatomy. Although available online to students, most of the accessible mnemonics are in English and non-native English-speaking students (students who are native Arabic-speakers) might find them difficult to understand. Therefore, we have created two simple Arabic mnemonics that can simplify the memorisation of the carpal and tarsal bones. We believe that Arabic mnemonics effectively enhance memorisation by linking the new learning material to familiar information.Keywords: Learning; Memory; Anatomy; Nursing; Carpal bones; Tarsal Bones; Oman.

Authors: Gatica Arreola Leonardo Adalberto
Published: July 2020

Objetivo: Avanzar en una explicación teórica sobre el efecto que tiene el sistema de partidos sobre el uso eficiente de los recursos públicos, particularmente sobre el uso clientelar del empleo gubernamental.

Metodología: Se desarrolla un modelo formal para abordar el problema antes descrito.

Resultados: Se presenta un modelo formal que logra capturar cómo el incremento del número de partidos políticos que compiten en una economía incentiva un mayor uso clientelar del empleo gubernamental.

Limitaciones: Si bien este trabajo busca explicar los resultados de otros análisis empíricos y avanzar en términos teóricos, únicamente presenta un modelo formal sin aportar evidencia empírica.

Originalidad: A saber del autor, hasta la fecha no hay en la literatura un modelo teórico que, enfocado en el uso del empleo gubernamental, explique los efectos que el sistema de partidos puede tener en el empleo clientelar de los recursos públicos.

Conclusiones: El modelo explica como la presencia de un mayor número de partidos genera nuevos grupos de votantes políticamente rentables, que pueden ser capturados por el partido en el gobierno mediante el ofrecimiento de empleo burocrático.
A Developmental Study of the Turkish Connectives
Authors: OĞUZ Enis , ÖZGE Duygu
Published: June 2020

Connectives present an interesting phenomenon; while even 3-year-olds can produce them accurately, the real mastery of understanding their meaning takes much time in language acquisition. We tested the comprehension of temporal, causal, and adversative connectives in 184 Turkish-speaking primary-school children and 20 Turkish-speaking adults. Our results demonstrated that high-achieving 5-graders show an adult-like performance. Regarding the type of the connective, temporal connectives posed greater challenge for children compared to causal and adversative connectives. We explain these results in light of the multi-dimensional account of connective acquisition.An Erratum to this article was published on 30 December 2020. http://dad.boun.edu.tr/en/pub/issue/58756/849534

Authors: Ranjbar Akram , Mehri Negar , Ghasemi Hassan , Dastan Dara , Kazemi Najafabadi Farzaneh , Dehkhodaei Narges , Kheiripour Nejat
Published: June 2020

Background: Studies have shown that organophosphorus pesticides such as malathion induces oxidative stress injury and tissue damage.
Objectives: This research aimed to determine the effects of the hydroalcoholic extracts of Satureja Avromanica (SA) on the liver function of malathion-poisoned animals.
Methods: Twenty-eight rats were divided into four groups of the control, SA (20 mg/kg), malathion+SA, and malathion. Animals received malathion 150 mg/kg and SA 20 mg/kg for one week through intraperitoneal injection. Then, their liver and blood samples were extracted, and alanine aminotransferase, aspartate aminotransferase concentrations in serum as well as biomarkers of oxidative stress such as Lipid Peroxidation (LPO), Total Antioxidant Capacity (TAC) and Total Thiol Groups (TTG) in the liver tissue were measured.
Results: The results showed that the SA administration reduced the level of liver LPO compared with that in the malathion group. Also, receiving SA increased liver TAC and TTG levels in rats, which this difference was significant compared with the malathion group. Besides, the SA group showed a significant decrease in liver enzyme levels, compared with the malathion-treated group.
Conclusion: According to the results, SA exerted protective effects against malathion poisoning, through reduction of oxidative stress. Therefore, SA may be an antioxidant to counteract the harmful effects of malathion poising in liver tissue.
Fabrication and Characterisation of Lavender Oil and Plant Phospholipid Based Sumatriptan Succinate Hybrid Nano Lipid Carriers
Authors: Reeta Rashid Mehmood , John Maria , Newton Amaldoss
Published: June 2020

Background: Nanostructured Lipid Carriers (NLCs) of Sumatriptan Succinate (SS) were prepared by using lavender oil. In ancient days, lavender oil was used for the treatment of a migraine. The natural anti-migraine agent, lavender oil, combined with an anti-migraine drug such as SS in a nano-formulation, will be a practical alternative approach in migraine therapy.
Objectives: Of sumatriptan succinate were fabricated by using a natural anti-migraine oil (lavender oil), LECIVA-S70, which is a specialized grade for liposomal dermatological preparation and designed for emulsion, fat infusions, nutraceutical formulations, and parenteral use. It contains 70% phosphatidylcholine, which is not generally present in the regular soy lecithin.
Methods: The central composite design technique was used to examine the relationship between independent variables and responses such as lavender oil and LECIVA-S70. The dependent variables were Z-average (R1), Polydispersity Index (PDI) (R2), and % entrapment efficiency (R3). The NLCs were prepared with the double emulsification technique. The Fourier transform infrared spectroscopy, X-ray diffraction, and differential scanning calorimetry analyzed the drug excipient compatibility profile. The developed NLCs were characterized for particle size by using Mastersizer, Zetasizer, and Transmission Electron Microscopy TEM). The membrane diffusion technique studied the in vitro drug release profile.
Results: The Mean±SD size of the NLCs ranged from 411.4±311.1 d.nm to 398.8±242.6 d.nm. The best formulation (SNE9) demonstrated an average diameter of 398.8±242.6 d.nm, with the PDI of 0.216, and zeta potential of 17.18 mV
Conclusion: The optimized formula demonstrated the narrow size range, a satisfactory zeta potential, high drug loading, and reproducible drug release profile. The NLCs successfully retained the aroma of the lavender oil. According to ANOVA, the PDI (R2) is significant with the central composite design.

Paleoкarst, hydrothermal karst and karst reservoirs of the Franian reefs
of the Rybkinsky group
Authors: Vilesov Aleksandr P. , Chertina Kseniya N.
Published: July 2020

More than 20 isolated reefs of the Rybkinsky group were discovered in 2015-2018 in the eastern part of the Rubezhinsky Trough, west of the Sol-Iletsky Arch (Orenburg region; southern part of Volga-Ural Oil and Gas Province), thanks to the use of seismic surveys 3D and exploration drilling. The interval of the stratigraphic distribution of the reefs encompasses Domanikian, Rechitskian and Voronezhian Horizons (=Regional Stages) of the Franian Stage of Upper Devonian. The reefs are cased and overlapped by carbonate-terrigene-clay deposits of the Kolganian Formation that form the seal. High-amplitude oil fields (up to 150 m high) are related to the bodies of reefs. Reefs developed under conditions of significant changes in sea level caused by both eustatic fluctuations and regional tectonics.
Actual data on features of surface and deep karst in different reefs of the Rybkinsky group are given. Three karst epochs are allocated: 1) late Domanikian; 2) late Rechitskian; 3) late Voronezhian. Evidences of the post-franian hydrothermal karst in the reefs are presented. Reservoirs formed as a result of karst are characterized by high complexity of pore space.
Reef reservoirs have a scale permeability effect that is necessary to consider in hydrocarbon reserve calculations.
Biodegraded bitumens dispersed in Vendian (Neoproterozoic) rocks of the Khatyspyt Formation, Northeastern Siberia
Authors: Melnik Dmitriy S. , Parfenova Tat’yana M. , Rogov Vladimir I.
Published: July 2020

The organic matter of the Vendian (Neoproterozoic) Khatyspyt Formation was investigated. The new data obtained from the GS and GS-MS analyses include: high UCM humps andheightened peaks of steranes and terpanes against the backdrop of C27+ alkanes on chromatograms of saturated hydrocarbons fractions of five samples; predominance of С21-С26 in n-alkanes distribution; the presence of 12- and 13-monomethylalkanes on chromatograms and demethylatedterpanes on filtered chromatograms (m/z 191 and 177). Besides, dispersed bitumens with biodegraded hydrocarbons have been for the first time identified in carbonate and carbonate-siliceous rocks of the Khatyspyt Formation. Also 8,14-sekohopanes resistant to biodegradation and gammacerane were established.
The revealed features of the composition and distribution of hydrocarbons showed that their source was the autochthonous (syngeneic) organic matter of the Khatyspyt Formation,one of the potential hydrocarbon source rock of Northeastern Siberia. The composition and content of bitumen are found to be controlled by the inputs of primary organisms (eukaryotes and prokaryotes)which lived in Vendian seas, by changing redox conditions of sediment deposition and transformation, as well as by relatively little effect of temperature and high degree of biological oxidation in hypergenesis.
The patterns of bitumen distribution throughout the section show, that besides the overlying deposits,their accumulations canbe discoveredin the Khatyspyt Formation.

This case study examines the disruptive nature of Google’s strategy in the marketplace to assist researchers and practitioners in future endeavors. From this research analysis, Google has been able to exploit its strengths of being an industry leader by way of new products as well as by the open lanes of communication of its flat organizational structure, which allows for creativity and design. Not all of the products have been winners, but that must not be a deterrent to the future progress of the company. This research is significant because Google’s competitors may obtain additional information to level the playing field, thereby dethroning Google’s superiority in the market.

This study examined the nexus between capital flight and economic development in Nigeria. The null hypothesis was that capital flight has no significant relationship with economic development in Nigeria. The study used the auto regressive distributed lag (ARDL) method on data obtained from the Central Bank of Nigeria and the World Bank, for the period 1986–2018, to examine the relationship between capital flight and economic development in Nigeria. The study examined the unit root problem and cointegrating properties of the data. The unit root problem was tested for by using the augmented Dickey–Fuller (ADF) and Phillips–Perron (PP) tests. Findings from ARDL showed an inverse relationship exists between capital flight, real exchange rate, and economic development. This implies that the variables contributed significantly to reduce economic development within the study period. However, a positive relationship existed between economic development and adult literacy rate in Nigeria. By implication, improvements made in providing quality and affordable education tend to have a positive impact on economic development in Nigeria. The study concluded that economic development is strongly influenced by capital flight, real exchange, and adult literacy rates in Nigeria. The study, therefore, recommends that government policies to curb capital flight should be introduced and monitored so as to lead to economic development in Nigeria.
Foreign Investments in the Chinese Bond Markets
Authors: Liu Kerry ,   China Studies Centre, University of Sydney, Sydney, Australia.

The Chinese bond market is the second largest in the world. However, studies on Chinese bond markets are very few, and especially there are no studies on foreign investments in the Chinese bond markets. This study fills the gap in the academic literature by focusing on foreign investments in the Chinese bond markets. By using the least-squares model with breaks, this study finds that although, in theory, the factors of exchange rate, yield spread, and yield correlation should play a significant role in attracting foreign investors to invest in the Chinese bond markets, the specific effects depend on the stage of the Chinese bond markets’ open-up. Initially, the main foreign investors are central banks and similar institutions, and they primarily consider more strategic factors than pure return or risk factors. As more institutional investors have entered the Chinese bond markets, the considerations of enhancing risks and/or reducing risks become more significant. The increasing foreign investments will be beneficial to the Chinese bond markets such as more issuance of longer-dated bonds, thus helping China to establish its RMB bond yield curve, and improving the market efficiency. The Chinese authorities should launch more policy initiatives to attract foreign investors.
“FALTA TEMPO, TEM QUE CORRER”: O TEMPO NA CONTEMPORANEIDADE E SUA CONCEPÇÃO NO CONTEXTO ESCOLAR
Authors: Furlan Susana Angelin , Lima José Milton de , Lima Márcia Regina Canhoto de
Published: July 2020

Este artigo retrata reflexões de uma pesquisa que investigou a aceleração do tempo na contemporaneidade e como esse movimento permeava a escola. A investigação é advinda de uma pesquisa de mestrado que contou com a participação de duas professoras e aproximadamente 50 crianças, observadas durante todo o ano letivo de 2017. Desta maneira, este estudo utiliza uma base teórica e filosófica para entender o movimento do tempo na atualidade e suas repercussões no contexto escolar. Notamos que essa aceleração do tempo, marco da sociedade contemporânea, já recai nas crianças numa antecipação do que elas são capazes de fazer. Dessa forma, é necessário atentarmos-nos às relações entre as crianças e seus pares e entre as crianças e os adultos, que são bases de um sistema educativo de qualidade. É imprescindível, também, desacelerar, para prestar mais atenção nos detalhes e nas singularidades.
A AULA DE FILOSOFIA COMO CRIAÇÃO CONCEITUAL E LABORATÓRIO CONCEITUAL
Authors: Gabriel Fábio Antonio , Pereira Ana Lúcia , Alves Maurício Silva
Published: July 2020

Este artigo tematiza a aula de Filosofia como momento oportuno para uma criação conceitual na perspectiva de Deleuze e Guattari (2010) e como laboratório conceitual na perspectiva de Carrilho (1987). O enfoque teórico adotado aponta no sentido de um ensino de Filosofia como experiência filosófica, distanciando-se de um ensino meramente enciclopédico e doutrinário. O objetivo é, assim, evidenciar as contribuições dos autores já citados para o ensino de Filosofia que proporcione ao estudante um relacionar da Filosofia com a experiência cotidiana. Os resultados desta pesquisa bibliográfica destacam a importância de considerar-se a aula como laboratório conceitual em que o estudante pode relacionar os conceitos filosóficos da tradição com os problemas da sociedade contemporânea em que está inserido.
The Need for a Unified Patent Court
Authors: Lucas Eugénio
Published: July 2020

This article discusses the need of a Unified Patent Court, as a major contribution for the implementation of the European unitary patent. It begins by outlining the evolution of European patent rights and identifying the problems of the current system. Implementing a Unified Patent Court will be defended as a solution for one of the most important problems of the European patent: the lack of a central mechanism of jurisdictional control. The current model of jurisdictional control gives rise to a situation of great legal uncertainty and has diminished the value of European Union patent rights. We will analyse the virtues and disadvantages of the new European Unitary Patent resulting from the adoption of Regulations (EU) 1257/2012 and 1260/2012 and the Agreement on a Unified Patent Court.
Reflections on the situation of nuns in the Roman Catholic Church with illustrative examples from Spanish-language literature
Authors: Grzyś Olga
Published: July 2020

In 2018 and 2019, the Vatican newspaper “L’Osservatore Romano” published two ground-breaking articles describing the psychological, physical and sexual abuse of nuns by clergymen of the Roman Catholic Church. The aim of this paper is to present the situation of consecrated women and the relationships between priests and nuns. The text will also attempt to discover possible reasons for the clergymen’s inappropriate behaviour towards nuns. To achieve this goal, the author refers to the status of women in the Catholic religion and examines documents issued by the Church that relate to the life and the functioning of women’s religious communities.
The second part of the paper presents fragments of Spanish-language poetry and prose whose authors or heroines are nuns. The selected texts address the problem of the clergy’s discrimination against nuns.
An in silico comparative genomic report on transcription factors in three Arabidopsis species

Published: July 2020

Transcription factors (TF) are the elements, which regulate gene expression. Regulatory function of TFs play an important role in plant biological processes and mechanisms. They may interconnect with other transcription factors or functional genes to modulate their expression in response to an internal/external factor like life cycle stage, growth, development and stress. Arabidopsis is the well-known and the most used model organism. Transcription factors of three Arabidopsis species including A. halleri, A. lyrata and A. thaliana, were compared. basic/helix-loop-helix (bHLH) with 220 TFs was the most abundant family among three Arabidopsis species while MYB and MYB related families considering as a whole group were more than bHLH with 308 TFs. No STERILE APETALA (SAP) TF homolog was found for A.halleri.  The common transcription factors among three species were 4,172 grouped in 1,212 clusters. The species-specific clustered TFs were 12, 30 and 58 for A. halleri, A. lyrata and A. thaliana respectively. Eight hundred ninety two single-copy gene clusters those have one gene copy from each species, i.e. 2,676 genes, were listed. Four hundred forty five TF singletons were not clustered and are unique among three species. For clustered TF belonging to each species, GO terms and SwissProt hits showed that A. halleri has two species-specific TFs involved in heavy metal response including Zinc finger protein AZF2 and two-component response regulator ARR11 while for A. lyrata specific TFs are involved in stress response and plant development. A. thaliana specific clustered TFs work on plant flower development and acclimation.

El trabajo presenta una solución de los balances de masa y energía para el sistema integrado por la columna destiladora de aguardiente de caña, el sistema calientavinos-condensadores, la torre de enfriamiento y el generador de vapor, para una destilería de aguardiente de caña cubana. El proceso se modeló en el simulador comercial HYSYS v3.2 y los resultados para el sistema calientavinos – condensadores se compararon con los balances realizados manualmente utilizando el diagrama de entalpía – composición para el sistema etanol – agua, representativo del equilibrio líquido vapor a 101,3 kPa, con el fin de verificar la validez del modelo de simulación. Los resultados difieren en menos del 5% por lo que el modelo reproduce el comportamiento del sistema. Con el modelo de simulación se analizó la influencia de la variación del flujo másico de batición y de la temperatura del vino a la salida del calientavinos sobre el flujo y composición del aguardiente producido, proponiendo como mejores condiciones de operación el trabajo al mayor flujo de batición posible (40 000 kg/h) y calentando el vino hasta 90 °C en el calientavinos. Se verificó el desempeño del generador de vapor que alimenta a la columna de destilación, comprobando la posibilidad de recuperación del 19% de la energía calorífica que se cede actualmente con los gases de combustión.
Deserción y reprobación, desde el enfoque del estudiantado en la educación superior, en el curso de Matemática General
Authors: Hidalgo Mora Randall , Gamboa Araya Ronny , Castillo Sánchez Mario
Published: July 2020

Este artículo describe la deserción y reprobación en el primer curso de Matemática en la Universidad Nacional de Costa Rica desde el enfoque del estudiante y traza líneas generales en cuanto a posibles causas. Este curso presenta altos índices de deserción y reprobación que repercuten en otras problemáticas, como el avance académico del estudiante. Además, genera implicaciones individuales y sociales en términos de las expectativas estudiantiles, familiares y emocionales por la discrepancia entre las ambiciones de los jóvenes y sus logros, así como consecuencias económicas para el sistema universitario.

En esta investigación se trabajó con toda la población de estudiantes matriculados en el I y II ciclo del año 2017. A ellos se les aplicó un cuestionario, vía correo electrónico, en el cual se les consultó sobre aspectos generales y posibles causas de deserción y reprobación.

El análisis arrojó los siguientes resultados: un alto porcentaje de deserción, independientemente del ciclo lectivo; un mayor porcentaje de aprobación durante el II ciclo, especialmente en las mujeres, posiblemente asociado a un proceso de aprendizaje o de adaptación a la vida universitaria; que la mayoría de los estudiantes proviene de colegios públicos y presenta mayor porcentaje de reprobación y que las causas de deserción priorizadas por los estudiantes son el bajo rendimiento académico, los conocimientos previos y los hábitos de estudio.

Al respecto, puede concluirse que resulta necesario generar políticas institucionales con las cuales sea posible disminuir la deserción y reprobación, específicamente en cursos de primer ingreso a la universidad y, por tanto, acortar tiempos de graduación y optimizar recursos institucionales.
