A través de las redes sociales el profesor Francisco Fuster ha hecho circular estas notas sobre los procesos de producción de los papers académicos que nos parece útil compartir con los lectores:

“Mi pasaje favorito de la extensa y deliciosa entrevista –memorable en su conjunto– que Julio Cortázar concedió a Televisión Española en 1977 es ese en que el presentador del programa “A Fondo”, el inolvidable Joaquín Soler Serrano, preguntaba al escritor argentino por qué motivo le costó tanto decidirse a publicar el primer libro firmado con su nombre real (la obra de teatro Los reyes, aparecida en 1949, cuando ya rondaba los 35 años) y no con el seudónimo de “Julio Denis”, con el que había presentado en sociedad sus primeros versos. La razón –argumentaba Cortázar con parsimonia, entre trago de whisky y calada al pitillo– es que no me sentía nada seguro… Honestamente, veía lo que había escrito hasta esa fecha como una especie de borradores –el desahogo de un adolescente– indignos de ser impresos y entregados al público. Además, añadía el autor de Rayuela, observaba con pudor y con vergüenza ajena que mis amigos de juventud literaria ya habían editado sus primeras obras: panfletos ingenuamente provocadores, de escasísima calidad objetiva, que en ningún caso justificaban tamaña inversión de papel y de tinta.

Publicamos este número de la revista en momentos muy particulares. El desarrollo de la pandemia del llamado corona virus ha determinado la suspensión de las actividades presenciales en las universidades argentinas y un esfuerzo de las instituciones por fortalecer programas de educación a distancia. Desde su inicio hace 9 años, la Revista Debate Universitario y paralelamente los libros académicos publicados por el área de investigaciones de la Universidad Abierta Interamericana fueron publicados en acceso abierto como parte de las transformaciones en desarrollo en esta época donde la virtualización de los procesos del conocimiento avanzan a escala internacional y se han fortalecido en el país. Con éste suman 16 los números publicados en la revista con más de 50 artículos académicos, casi todos sobre el sistema universitario argentino y algunos sobre otros países latinoamericanos. Este fondo de conocimiento de uso permanente por la comunidad académica se suma a los libros publicados en colaboración con la Editorial Teseo sobre la problemática universitaria destacándose la gran cantidad de lectores que acceden a los mismos.

En este número además de artículos sobre diversas problemáticas universitarias, publicamos un conjunto de notas de especialistas sobre la experiencia vinculada al desafío planteado por la actual coyuntura.
Del aula presencial al aula virtual universitaria en contexto de pandemia de COVID-19
Authors: De Vincenzi Ariana
Published: December 2023

El ciclo académico 2020 se vio interrumpido en su modalidad presencial en todos los niveles educativos y sistemas de educación a lo largo del mundo. Millones de docentes y estudiantes debieron reaprender una nueva manera de acceder al conocimiento y de interactuar en el ciberespacio. Incluso los más resistentes a la cultura digital tuvieron que involucrarse en este proceso de aprendizaje y apropiación tecnológica.

El proceso de adaptación de la actividad docente presencial a la modalidad virtual es una situación provisional ya que en algún momento se retomará la actividad docente en los edificios universitarios. Pero esta crisis sanitaria que impacta al mundo entero ha provocado en la docencia una enorme oportunidad para repensar la forma en que se concibe y ejerce el proceso de enseñanza, para reflexionar sobre dónde y cómo enseñamos y mejorar ambas dimensiones de la práctica educativa cuando retomemos la presencialidad.

Si bien es cierto que la educación mediada por tecnologías lleva varias décadas en la educación formal, también lo es la resistencia evidenciada en algunos “claustros docentes” a abandonar prácticas tradicionales a favor de las innovaciones que proponen las tecnologías al servicio del aprendizaje. En este artículo se analizará el proceso de configuración del aula virtual universitaria a cargo de profesores habituados a la presencialidad, las limitaciones y fortalezas que se relevan en las  prácticas docentes y las oportunidades que se avizoran.

El COVID-19 y la investigación social
Authors: Wainerman Catalina
Published: December 2023

La pandemia que nos arrasa, sin duda será una bisagra en la historia de la humanidad y, even- tualmente, del planeta Tierra, porque no solo los humanos estamos siendo afectados, también todos los seres vivos y el medio ambiente en el que los humanos hemos hecho destrozos. Pero como la vida tiene que seguir y nosotros ayudar a que eso ocurra, me propuse aprovechar la pandemia del Coronavirus para lo que es “lo mío”, contribuir con una reflexión para avanzar en el pensamiento lógico y vincularlo a la metodología de la investigación social. ¿Para quién? Para quienes como yo tienen la pasión de convertir “los deshechos en abono”,2 lo que de manera más elegante podría traducirse en transmutar “lo profano en lo sagrado” o, de manera más complaciente, “las desgra- cias en oportunidades”.

Para hacerlo hay que desdoblarse y adoptar un distanciamiento intelectual y emocional que nos permita salirnos de nuestro papel de actoras/es sociales y adoptar, en simultáneo, el de observa- doras/es con una mirada sensibilizada por las Ciencias Sociales y por la lógica de la investigación científica.

The life of modern society is busy every day with work, going to work in the morning and coming home in the afternoon, even late at night. In addition, they usually pay little attention to eating and physical activity, even though most of the work in the office is done sitting down, so that the person is physically inactive. Gowa Regency, this study used a descriptive research method which is a method for examining the status of human groups, an object, a set of conditions, a system of thought, or a class of events at the present time. This research was carried out in Kab. Gowa. The collection of physical fitness data is carried out using a standardized test, namely the Indonesian Physical Fitness Test (TKJI). TKJI is divided into 4 age groups, namely: 6-9 years, 10-12 years, 13-15 years, and 16-19 years. In this study, the research subjects were Insan Cendekia SMA, totaling 20 people. The instruments used in this study were to measure a healthy lifestyle and measure the level of physical fitness of Gowa Cendekiawan High School students. The number of players in each rating category obtained by players is very good 0%, good 25%, enough 55%, less 20% and very less 0%. Based on the results of the normality analysis, it can be seen that the normality test data is normally distributed. This is evidenced by the Kolmogorov-Smirnov sig value greater than α = 0.05 (0.279 > 0.05) and the Shapiro-Wilk Sig value greater than α = 0.05 (0.807 > 0.05. If if the Sig value is less than α=0.05 then the data is not normally distributed whereas if the Sig value is greater than the value α=0.05 then the data is normally distributed.The results of a healthy lifestyle survey are that the category is always in accordance with a healthy lifestyle 0% , often 95%, sometimes 5% and never 0%.The results of the correlation value of the relationship between a healthy lifestyle and the level of physical fitness is 0.126, meaning that the level of the relationship is quite close.With the results of the analysis above, there is a relationship between a healthy lifestyle and a level of fitness physical high school scholars, Gowa regency.

Authors: Kiosidou Evangelia D. , Liarokapis Dimitrios E. , Tzabiras Georgios D. , Pantelis Dimitrios I.
Published: December 2023

In this work, an experimental investigation of the hydrodynamic resistance of a flat plate painted with newly developed marine antifouling paints of polyurethane (PU) and silicone (Si) formulations was performed. In total, six different paint systems of Si, PU, and acrylic formulations were applied, both experimental and commercial. The total resistance of each painted condition of the plate was measured through towing tank tests for the range of 0.75–2.5m/sec, with a step of 0.25m/sec. The Si and PU formulations exhibited similar hydrodynamic behavior, fluctuating around the smooth condition, whereas the acrylic system exhibited the highest resistance increase of all. The roughness function calculation was based on Ra and the correlation with the Colebrook roughness function was generally limited for most systems. Extrapolation to ship scale revealed that no significant drag differences are expected in the as-painted condition among the different paint system types.
Which robust regression technique is appropriate under violated assumptions? A simulation study
Authors: Kim Jaejin , Li Johnson Ching-Hong
Published: December 2023

Ordinary least squares (OLS) regression is widely employed for statistical prediction and theoretical explanation in psychology studies. However, OLS regression has a critical drawback: it becomes less accurate in the presence of outliers and non-random error distribution. Several robust regression methods have been proposed as alternatives. However, each robust regression has its own strengths and limitations. Consequently, researchers are often at a loss as to which robust regression method to use for their studies. This study uses a Monte Carlo experiment to compare different types of robust regression methods with OLS regression based on relative efficiency (RE), bias, root mean squared error (RMSE), Type 1 error, power, coverage probability of the 95% confidence intervals (CIs), and the width of the CIs. The results show that, with sufficient samples per predictor (n = 100), the robust regression methods are as efficient as OLS regression. When errors follow non-normal distributions, i.e., mixed-normal, symmetric and heavy-tailed (SH), asymmetric and relatively light-tailed (AL), asymmetric and heavy-tailed (AH), and heteroscedastic, the robust method (GM-estimation) seems to consistently outperform OLS regression.

Published: December 2023

A política urbana brasileira apresentou, desde o final da década de 1980, inserção equitativa de segmentos populares em diversos canais de participação popular. Além da Constituição Federal de 1988 e o Estatuto da Cidade de 2001, também foram importantes nesse processo de fomento e efetivação da participação nas políticas públicas urbanas no transcorrer dos anos 2000, a criação do Ministério das Cidades (2003) e de conselhos diversos, entre os quais o Conselho das Cidades (ConCidade) em (2004) que passou a compor a estrutura do Ministério das Cidades. Assim, tendo por base esse contexto e a cidade de Londrina localizada no Norte do Paraná, objetiva-se analisar a representatividade da participação social como elemento constitutivo e constituinte do processo democrático de construção de direitos sociais. Por se tratar de uma pesquisa de abordagem qualitativa, a interpretação da realidade ocorreu por meio do materialismo dialético, método esse capaz de abranger a totalidade e apresentar a realidade como síntese de múltiplas determinações, partindo da materialidade do real, do mundo empírico existente. Verificou-se no decorrer da pesquisa que, a partir de 2012, ocorreu um impasse na implementação do ConCidade, no âmbito municipal, motivado pelo conflito de interesses entre agentes produtores do espaço urbano e segmentos populares. Nessa disputa ocorreu a fragilização dos grupos populares e a interrupção da criação de um conselho da cidade com legítima participação popular. Com a aprovação da revisão do Plano Diretor, o município dispõe de uma nova instância participativa desde 2022 através do Conselho Municipal de Planejamento e Gestão Territorial.

This study aimed to determine the prevalence of Campylobacter species in milk and its product samples in Karbala province and detect the antibiotic sensitivity of these isolates. One hundred samples were aseptically collected as follows: 50 samples of bovine raw milk and 50 samples of bovine milk products from different local shops and farms distributed in Karbala province, in addition to, 100 samples from children suffering diarrhea, fever, and abdominal pain from Kerbala (Iraq) General Children's Hospital. The pathogen was found using biochemical testing after samples were immediately inoculated into enriched and sub-cultured on selected media. Campylobacter spp. At 24 to 48 hours, colonies on the plate are small, often grayish in appearance, although some have to be creamy grey, slightly raised and moist, and often generated separate colonies of bacteria, flat with irregular borders, and non-hemolytic. This was confirmed by using the polymerase chain reaction method, 11 isolates (5.5%) of 200 samples were determined to be Campylobacter species. The 11 isolates were subjected to sequencing to detect the species of Campylobacter which found two species (C. jejuni and C. upsaliensis). Results showed that Campylobacter spp. 11 positive isolates, C. jejuni recorded 9 (81,8%) positive results while C. upsaliensis recorded 2 (18.18%) positive results. Antibiotic_ susceptibility_ test was cultured by using disk diffusion assay, campylobacter spp. showed complete sensitive  to ciprofloxaci , gentamycin, and Imipenem.
Efficacy of Chemical and Biological formulations, and Plant extracts on the mortality of the third larval stage of tomato leaf moth Tuta absoluta (Meyrick 1917) (Lepidoptera: Gelechiidae) in vitro
Authors: Saeed Khaldoon Faris
Published: December 2023

Tomato in Iraq and most Middle East areas can be infected by tomato leave moth which contributes to reducing the total yield. Utilization of pesticides may lead to resistance problem in most of treated pests, which make the control of this difficult. In addition, chemical pesticides can cause climate pollution, and high cost if use continuously.  Thus, this study investigates the efficacy of some of chemical and biological formulations and two plant extracts and its combinations in killing of the third larval stage of the insect. Three concentrations (field dose -50%, field dose and field dose +50%) for each of chemical insecticides (Coragen, Simpleo, and Acetamprid) and bioformulation of (Bacillus thuringiensis), and the mixture of oil extraction of garlic and Neem. Result showed that there is a significant variation between the concentration of treatments, third concentration (field recommended dose + 50%) gave the higher mortality. Treatment with Acetamprid insecticide showed a significant efficacy after 72 hours which achieved 83.33%, then Coragen insecticide by 56.66%. While, Sumipleo insecticide gave the lower mortality 36.66% of the third larval stage. The combination of evaluated factors and time exposure showed the superiority of (Bt + Coragen + Mixture of neem and Garlic oils) integrated treatment by achieving mortality of 86.66% after 72 hours of treatment, followed by mixture of garlic and neem oils 76.66% and treatment of (Bt + mixture of neem and Garlic oils) by 71.65%, while the treatment of (Bt+ Sumipleo + mixture of garlic and neem oils) gave the t mortality of 45.00% only.

The purpose of this service is to help convey information related to the introduction of the basics of presentations and their media to provide them with basic public speaking experience by making and carrying out simple interactive presentations that will be developed and used at the next level and even up to the world of work. One of the uses of technology in this digital era is the use of digital applications to assist presentation activities. One of the applications commonly used in today's circles is the Microsoft Office PowerPoint application. This application can be accessed via computers based on the Windows operating system and Apple Mac OS. In this service, we will introduce this application as an illustration of using the application to help with presentation activities. However, the level of confidence of elementary school students in speaking in public is low. Even though this skill is a mandatory stage that must be passed and will be useful for the future. From these problems, community service activities are carried out by providing basic knowledge of introduction to presentations and the basics of public speaking skills to increase students' confidence to speak in public. The implementation method used in this activity is (1) providing basic material in good and correct presentations, (2) introducing commonly used media, (3) providing opportunities and assistance in simple presentation practices. The result of this activity is an increase in students' basic knowledge and skills in presentations, so that students become more confident to be able to appear in public along with the possibility to improve their abilities to be better than before.
Militant Rule of Law

Published: December 2023

To protect the rule of law based legal system against abusive use of the loopholes, imperfections, contradictions of the law, to avoid legal inertia legal positivist arguments are needed to convince and mobilize the legal mind. The same applies when the blind fortune of democracy provides the opportunity to erase the legally enthroned injustice and domination of illiberal regimes. When it comes to legal enactments that serve legal cheating the rule of law must respond to systemic abuse of the law, and that requires and justifies a rule of law based exceptionalism and a systemic remedy.

Published: December 2023

De los costos de un sistema de producción, las actividades de labranza son de los más altos, pues demandan mucha energía y los combustibles derivados del petróleo incrementan sus precios continuamente. El propósito de este trabajo fue calcular y analizar los costos de dos sistemas de labranza de conservación: labranza vertical y labranza cero, para compararlos con los de la labranza convencional que normalmente se utiliza para producir avena para forraje seco, en la Región Sureste del estado de Coahuila. Para el cálculo de costos, se midió lo siguiente: el uso de combustible por cada una de las labores de los sistemas estudiados, las capacidades de trabajo con cada implemento, el rendimiento del cultivo, el costo del tractor utilizado como fuente de potencia, y el costo de cada uno de los implementos. Con los costos totales de cada sistema de producción y los beneficios de la producción bajo cada sistema, se calculó el índice de beneficiocosto. El mejor beneficio-costo se obtuvo con el sistema de labranza vertical, que tuvo un índice de 2.19, lo que significa que por cada peso invertido en este sistema de producción se obtienen 1.19 pesos de utilidad; luego le siguió el sistema de labranza convencional, con un índice de 2.02, lo que arroja una utilidad de 1.02 pesos por cada peso invertido y, finalmente, con el sistema de cero labranza se logró un índice de 1.98, lo que representa una utilidad de 0.98 pesos por cada peso invertido. En las condiciones del estudio realizado, el mejor sistema en relación con el beneficio-costo fue la labranza vertical, pues tiene una diferencia entre 14% a 17% de mayor beneficio respecto a los otros dos. Los sistemas convencionales y cero labranzas tuvieron un beneficio-costo muy similar entre ellos, pues sólo existió una diferencia de 3% entre ambos.

Published: December 2023

Para tener un mejor rendimiento en las cosechas, el uso de la tecnología en la agricultura se ha hecho indispensable; sin embargo, con este propósito es necesario recopilar información de los campos de trabajo para realizar análisis, interpretaciones y aplicaciones, y así optimizar el tiempo y los costos de producción en los cultivos. El objetivo de este trabajo fue evaluar mapas de dosificación variable; para lograrlo, se generó un mapa de prescripción utilizando el software Farm Works Mapping de Trimble con un previo levantamiento topográfico del sitio de trabajo (560 m2), realizado con la pantalla FmX que cuenta con la aplicación WMSurvey y una corrección satelital RTK de alta precisión. Además, se evaluaron los mapas con un diseño experimental completamente al azar con arreglo de parcelas subdivididas mediante tratamientos de dosificaciones: 40, 60, 80, y 100 000 semillas ha-1; también se utilizó un controlador de dosificación Field IQ de Trimble, que se ajustó a la sembradora a un espaciamiento de hileras de 0.80 m con el propósito de que mediante los sensores se registraran semillas ideales, los cambios de dosificación de acuerdo con los mapas, la regularidad de dosificación, y se elaboraran las ecuaciones de transferencia que permitieran observar los tiempos de respuesta entre dosis, por medio de las siguientes variables: cantidad de semillasm-1 y tiempo de caída de las semillas.
Observación sobre el arbolado de la "alameda Zaragoza" de Saltillo, Coahuila, con especial referencia a su estado de vigorosidad
Authors: Flores Flores Jorge David , Almanza P Blanca Estela
Published: December 2023

El presente trabajo es de carácter básico cuyos objetivos fueron: conocer la diversidad y abundancia de las especies arbóreas; determinar su estado de vigorosidad y factores que la deterioran. Para tal fin, el estudio se realizó en forma de censo en todo el arbolado de la Alameda Zaragoza, en Saltillo, Coahuila, avanzando triángulo por triángulo. Las variables que se observaron fueron: a) composición botánica b) etapa fisiológica del arbolado y c) condición de vigorosidad. Estas dos últimas se estimaron en función a las clasificaciones pro- puestas por Caballero y Zerecero (1978), y Hitchings (1984). 

De acuerdo a los resultados obtenidos, se detectaron 31 especies arbóreas, de las cuales 13 de ellas son consideradas raras para la región y 7 no son comunes ni recomendables para uso urbano. Se cuantificaron 1776 árboles, de los cuales el 41.5% pertenecen al troeno. En otro grupo de árboles dominantes está el fresno, el olmo, el arce, el nogal, el ciprés y una acacia. 

El 73.26% de los árboles existentes en la Alameda son maduros y sobre- maduros en condiciones sumamente deterioradas, para lo cual recomendamos que sean extraidos y sustituidos por nuevos individuos. Se dan a conocer los factores de deterioro para cada especie y árbol en particular y se dictan las medidas técnicas que deben de aplicarse para todo el arbolado de la Alameda.
Les entrepreneurs ont-ils cru dans leur(s) mythe(s) ? Mettre en dialogue l’entrepreneuriat et l’effondrement
Authors: GERMAIN Olivier
Published: December 2023

Le mythe de l’entrepreneur paraît sévir sans pour autant qu’on paraisse le saisir tant il confond héroïsme et figure individuelle. Qui est vraiment dupe, nous suggère Paul Veyne ? Cet essai interroge la tension entre mythification et mystification à l’ère d’un renouvellement des mythes au profit de la startup. Ce renouvellement du mythe contribue-t-il à la reproduction d’un « monde mauvais » ou est-il réparateur face à l’effondrement ? L’essai interroge également la performance ou la réalité du mythe pour les populations vulnérables ou mises aux marges de l’entrepreneuriat mais aussi le piège d’une réflexion centrée sur les identités au mépris des vies. Finalement, l’essai nous interroge sur les possibilités d’un activisme entrepreneurial, porteur d’imaginaires, ou d’un entrepreneuriat politique, créateur de relations avec et dans le vivant, qui porterait les possibilités ou dérives d’une autre mythologie.
Social media and digital communication during the pandemic
Authors: PLATANIA Federico , TOSCANO HERNANDEZ Celina
Published: December 2023

During the first wave of COVID‑19, the uncertainty about a prospect vaccine combined with the constant media bombardment have fueled the fear of strict periods of confinement measures, creating a fertile ground for fake news and misleading social media debates. This paper studies how the public attention to certain pandemic-related topics and the social media activity of health and policymaker influencers impact the energy sector. Our findings suggest that during periods of growing attention to the term “Coronavirus”, social media activity of policymaker influencers exhibits a negative relationship with the energy sector. However, given the positive and scientific connotation, when the public attention to the term “Vaccine” increases, we observe a positive impact of international health organizations.
De la promesse entrepreneuriale à la réindustrialisation : les cas de Florange et Gandrange dans la vallée sidérurgique lorraine
Authors: RIOT Elen
Published: December 2023

Entrepreneurs embody a promise for the future in territories in industrial crisis. We identify two types of entrepreneurs: continuity entrepreneurs, who promise industrial revival and disruptive entrepreneurs, who promise a green growth. Can these figures now repair what creative destruction and globalization have destroyed? We propose an analysis of the discourses around these entrepreneurial promises in the case of the Lorraine steel industry in Gandrange and Florange. We emphasize the highly ideological and indeterminate nature of the debate on industrialization and its promises for society, between deindustrialization, reindustrialization and the great environmental transition. This debate focuses on one man’s action, a providential figure and the promise remains a matter of personal belief.

Published: December 2023

Our study analyses the social function of the profit-as-success discourse as it developed in France in the 1980s. During this period, an open relationship to profit—a cultural import from the U.S.—replaced the traditional culture of silence regarding money. To examine this phenomenon we focus on media treatment of the entrepreneurial figure personified by Bernard Tapie. Our analysis shows that the main function of the profit‑as‑success discourse is to mask the modalities of construction and distribution of this same profit by companies. Our work provides a better understanding of the mechanisms of diffusion of a managerial discourse in the public sphere and its impact on society.

This study examines the relationship between profitability projected by ROE and liquidity by CR to predict its effect on projected dividend policy with dividend payout ratio (DPR) in food and beverage sector manufacturing companies listed on the stock exchange market. Design and method of analysis, estimation of pandel data regression models with CEM, FEM and REM approaches using the EViews v.12 program. Approach model selection with Chow test, Hausman test, and LM test. The classical assumption test refers to the results of the best panel data regression model selected. The feasibility evaluation of the model was carried out by regression analysis of panel data, and analysis of the coefficient of determination, as well as the t test and F test, at a = 0.05. The results of the study, FEM as a regression model of selected panel data. Evaluation of the feasibility of the model, ROE and CR can predict changes in DPR behavior, although there is an inverse relationship of CR with DPR. The joint contribution of ROE and CR has a high ability to predict and influence the DPR. ROE has a significant negative effect on the DPR. CR has no influence on the DPR. Together, ROE and CR have proven to have a significant positive effect on the DPR.
Demografske determinante starenja stanovništva SR Jugoslavije. Modelski pristup
Authors: Penev Goran
Published: December 2023

U radu su sagledani osnovni pravci i intenzitet promena starosne strukture stanovništva SR Jugoslavije, njenih republika i pokrajina u periodu po završetku Drugog svetskog rata. Posebna pažnja je posvećena demografskim determinantama starenja stanovništva, naročito između 1961. i 1991. godine. Za procenu uticaja promena fertiliteta, mortaliteta i spoljnih migracija na transformaciju starosne strukture korišćen je metod projekcija. Analiza je zasnovana na rezultatima simulacije četiri modela stanovništva koja su konstruisana polazeći od inicijalne starosne strukture iz 1961. i na bazi različitih kombinacija pretpostavki o kretanjima fertiliteta i mortaliteta u narednih 30 godina. Efekti promene komponenti demografskog rasta na odvijanje procesa starenja su dobijeni poređenjem starosnih struktura modelskih populacija u 1991. godini. Autor zaključuje da je pad fertiliteta direktno ubrzavao starenje od baze starosne piramide, ali posredno i starenje s vrha. Promene u smrtnosti stanovništva su dvostruko delovale na proces starenja: zbog opadanja smrtnosti mladih one su ga usporavale, a istovremeno su ga ubrzavale zbog produžavanja očekivanog trajanja života starih. Posmatrano u celini, u SR Jugoslaviji je pad mortaliteta u periodu 1961-1991. uzrokovao sporije odvijanje starenja, ali je njegovo dejstvo na promenu starosne strukture stanovništva bitno manjeg značaja od suštinski suprotnog dejstva koje je bilo prouzrokovano promenama fertiliteta. Spoljne migracije tj. negativan migracioni saldo su na nivou SR Jugoslavije imale najmanjeg uticaja na proces starenja. lako je dejstvo migracija vrlo slabo, one su takođe uticale na ubrzanje procesa starenja.

RETURNS TO EDUCATION UNDER THE HUKOU SYSTEM: WHAT IS THE ROLE OF SCHOOL TYPE?
Authors: Huang Juan
Published: December 2023

Purpose – Estimating the gap in returns to education between China’s urban and rural areas based solely on education attainment can be misleading, especially when there are significant differences in the allocation of educational resources between urban and rural areas. This paper explores the relationship between school types, primarily representing the educational resources available in China, and education returns in urban and rural China under the Hukou system.Methodology – This paper used data from the 2013 Chinese Household Income Project (CHIP) and applied the OLS method to estimate the traditional Mincer and extended models by adding school types.Results – Firstly, we found that school types significantly impact income, and different types of schools have different returns on education. The returns to school type increase with the geographical administrative level of the school. In addition, in most cases, the impact of key schools on the income of urban people is more significant than that of rural people. Secondly, when we consider the effect of school type on income, the gap in education returns between non-agricultural Hukou groups and agricultural Hukou groups is widened compared to the results under the traditional Mincer model. Finally, migration does not appear to have brought the desired improvement to their education, with the returns to education for migrants being significantly lower than rural in some cases.Implications – For individuals, especially those rural Hukou holders, investment in education should be strengthened to improve access to key schools. Providing equal access to quality education and reducing educational disparities between urban and rural areas is essential for the government.Originality/Value – The results highlight the role of inequality in the allocation of educational resources and the inequality of educational opportunities among the groups with different Hukou statuses and also show that migrating to urban areas may place migrants in a more adverse environment.

ABSTRACT
The knowledge, skills, competencies and skills required for entrepreneurship are tools that can be provided through entrepreneurial education. In this research, entrepreneurial intention in university students has been little explored, even though it is viewed as an important potential in business activity. The objective of this study is to identify and analyze whether entrepreneurial education, the university environment and family social capital are determinants of entrepreneurial intention. A study was carried out with a quantitative approach and a cross-sectional design, using the multivariate analysis of linear regression and the analysis of variance (ANOVA) of one factor. A random survey was applied to 384 university students from the southwest of the state of Guanajuato, through google forms. Only 318 surveys were validated, of which 49.4% are of a Higher Technical University level, 33.6% of a bachelor's degree and 17% of engineering. The findings show that entrepreneurial education helps in the development of the initiative in (4.28), the university environment identifies business opportunities (4.19) and the family union promotes entrepreneurship (4.59). In this same sense, six out of 10 students intend to start their own company when they finish their studies. Therefore, a higher positive correlation is observed between the university environment and entrepreneurial education (0.673). The results allow us to affirm that, in the case of men, the university environment has a greater significant influence on their intention to undertake, and for women, entrepreneurial education has a significant impact on their intention to undertake. Finally, family social capital is more favored in the case of men than women. The study has important implications for higher education institutions in terms of analysis, design, and management of entrepreneurial intent.
Keywords: entrepreneurial intention, entrepreneurial education, university environment, family social capital.

Dünyada nüfus artışına bağlı olarak artan gıda ihtiyacı ile tarımsal üretim de giderek yaygınlaşmaktadır. İnsan odaklı bir faaliyet olarak tarım, karbondioksit (CO2) ve metan (CH4) gibi gazların emisyonlarının sebep olduğu sıcaklık artışı olarak tanımladığımız küresel iklim değişikliğinde hem etken hem edilgen rol oynamaktadır. Dolayısıyla Dünyada ve Türkiye’de tarımdan kaynaklanan sera gazı emisyon hacminin artışı çevre tahribatı açısından önemli riskler taşımaktadır. Bu riskleri azaltmak için tüm dünya ülkelerinde çeşitli tedbirler alınmakta ve politikalar uygulanmaktadır. Bu bağlamda çevre dostu üretim yöntemleri ön plana çıkmakta olup, İyi Tarım Uygulamaları (İTU) ilk sırada gelmektedir. Toprak, su, hava, bitki örtüsü ve doğal kaynakların korunmasına odaklanan İTU aynı zamanda kaliteli, güvenli ve sağlıklı gıda üretimini de amaçlar. Dolayısıyla İTU küresel iklim değişikliği ile mücadelede başarılı bir tarımsal üretim şeklidir. Ayrıca üretim şekli itibari ile üreticilerde oluşturduğu çevre ve iklim değişikliği farkındalığı açısından da önemlidir. Dünya genelinde İTU’nın giderek artması üretici tercihleri yansıra tüketici tercileri ve beklentisi de bu yöntemin gelişmesini teşvik etmektedir. Tüketicilerin gıda güvenliği konusundaki arayışları ve sürdürülebilir çevre endişeleri İTU’nı daha da önemli hale getirmektedir. Bu çalışmanın amacı İTU yapan üreticilerin küresel iklim değişikliği farkındalığının ve bilinç düzeyinin ölçülmesidir. Çalışmada İTU’ında üretici sayısının yaklaşık olarak yarısının yer aldığı TR22 bölgesindeki (Balıkesir, Çanakkale) 165 üretici ile anket yapılmıştır. Çalışmada üreticilerin küresel iklim krizinin tarım üzerine etkisinin daha çok algılandığı fakat tarımın iklim değişikliğine olumsuz etkilerinde üretici farkındalığının yeterli olmadığı tespit edilmiştir. Ayrıca İTU da pazarlama destek ve politikalarının gerekliliği tespit edilmiştir.
