Published: September 2023

In the last two decades there has been an increase in research and discussion regarding curriculum in Higher Education (HE). The literature in this field tends to focus on curriculum change at either the whole institution or individual program or unit level. Formal writing on HE curriculum also does not offer a framework that openly draws upon context, learner needs, pedagogical approaches, and industry requirements to formulate a collaborative model of curricular development. To fill these gaps in HE curriculum discussion and literature, this paper will examine a new approach to curricular design - a cross-disciplinary model applicable to both unit (academic module that makes up a program) and program (degree) levels of curriculum development. This model has been developed by drawing on elements of Agile mindset and Backward Design and we call it Agile Backward Design (ABD).In ABD, the researchers have constructed a dynamic, and responsive framework that has been foundational in the design and development of innovative curriculum and pedagogy at the unit and program level of undergraduate degrees in both IT and education discipline areas. A case study approach is used to discuss the transformation that was made at the program and unit level.

Air circulation and thermal comfort are some of many factors that affects user’s behavior in indoor activity, particularly in learning activity. With appropriate air quality and thermal comfort, it is easier for students to focus on the learning process. In addition, better air circulation can also benefit to the health of the people inside the building, for instance, according to WHO (World Health Organization), appropriate airflow may reduce the spread of SARS-CoV-2 which lately has caused a COVID-19 pandemic. However, air circulation and distribution have not a concern yet due to existing room condition and advanced technology that is needed, in L 609 classroom and Heat & Mass Transfer Laboratory, in this research. CFD method implementation for this case is used to show existing air circulation condition and necessary recommendations to get better air circulation. CFD simulation is done 3 dimensionally with 44344 nodes tetrahedral mesh on 2 configuration room condition, which are classified based on air input from AC, door gap, and with or without window opening. Based on CFD simulation results, the 2nd configuration with window opening indicate the best configuration with air velocity around 0,8 m/s dan room temperature 295,8 – 302,1 K. With window opening, the air flow condition met the ANSI/ASHRAE 55 and hoped to reduce COVID-19 spreading.

Andon refers to an information system aimed at management, maintenance, planners, or other workers regarding quality, process, or quantity issues. To support accurate data communication, a reliable protocol and high precision are required. The Modbus TCP/IP protocol is compatible with Andon systems. This study aims to analyze the implementation of Modbus TCP/IP communication in the application of production data visualization in online production systems. At a certain distance, the antenna's data must display the data's precision in real time. The average data transfer time at the farthest distance tested, 50 meters, was 0.0043 seconds, indicating that the longer the distance between the client and server, the longer the waiting time tends to be, but does not exceed 0.01 seconds if it does not affect production activities. These results are still pertinent to the information required by the organization.

Published: September 2023

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic forming using V-bending dies process and Electrolytic zinc-coated steel sheet (SECC/JIS G 3313) material. The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.

Today's cybercrime methods are extremely diverse. The methods employed by attackers are becoming more diverse and intricate. Malicious software, commonly referred to as malware, is utilized in these various attacks. Malware threats and their propagation can be accomplished in several different ways. Good governance facilitates prevention via migration, assisting the security team and network infrastructure IT. This paper discusses efforts to enhance the security of the Simple Network Time Protocol (SNTP) to detect cybercrime on the network. Based on the results of the conducted experiments, we determined that by updating the Simple Network Time Protocol, implementing the client-server antivirus, and scanning every client connected to the local network or centrally, we could detect the types of attacks that frequently occur on the network system, thereby protecting all client computers from malware, viruses, worms, and Trojan horses. Based on the antivirus migration data, the employed research method can find information on cybercrimes that involve malware that enters the network and is successfully cleaned or quarantined before being automatically blocked.

A custom spray coating refill equipment has been designed and fabrication. For this reason, it is necessary to trial the equipment that has been made. This study aims to determine the performance of custom spray coating refill equipment. For a comparison parameter, coating and thinner mixture variations were conducted to determine the adhesion and thickness of the coating layer formed. The coating used in this experiment was Nitrocellulose (NC) and Polyurethane (PU) thinner. The ratio of coating and thinner mixture used are 1:1.5, 1:2, and 1:2.5. After mixing, the mixture was put into the sprayer using custom spray paint refill equipment. The mixture of coating and thinner was sprayed onto the SPCC steel plate. To measure, the adhesion and thickness of the coating layers, a cross-cut tool (according to ASTM-D3359) and a thickness gauge (according to the ASTM-AMT15) were carried out respectively. It seems the spray paint refill equipment was functioning properly. This is due to the quality of the coating layers having good adhesion, shown by all specimens getting 5B classification (0% not peeled off). Moreover, an increase in the thinner composition is lead to a decrease in the coating thickness.

The wheels of electric rail cars are an essential component of rail transportation when they are in use. At the time of inspection, the technician discovered damage to the wheel's surface. This is due to the hardening of the brake block, which damages the wheel's surface. This research was conducted with the purpose of analyzing the causes of damage to the tread surface of the wheels and identifying a suitable replacement for the original brake block, which is no longer manufactured and has been replaced by imitation block brakes. so that further action can be taken to prevent similar occurrences in the future. Using the Vickers hardness test indentation method, the purpose of this study is to examine various heat treatments for determining a material's hardness level. The test results indicate that the VHN value increases with increasing heating temperature. The original specimen produced 99.5 VHN in the first test without heat treatment, while the X block brake produced 26.9 VHN and the Y brake produced 136.0 VHN. The second test with 200°C heat treatment on the original specimen yielded 96.8 VHN, 73.1 VHN from the X block, and 152.9 VHN from the Y block. In addition, the third test with 400°C heat treatment on the original specimen produced 92.4 VHN, 47.8 VHN for the X block brake, and 268.3 VHN for the Y block brake. The Vickers Hardness Test (VHN) hardness value is affected by heat treatment; the higher the heating value, the higher the hardness value of the remolok specimen.

Published: September 2023

A tensile testing machine with a lower load capacity is needed to identify the mechanical properties of composite materials. Tensile testing machines for composite materials are available in the market but at high prices. Previously, using a pneumatic system, a tensile testing machine for composite materials with a maximum load of 2000N was developed. However, this tensile test machine still needs improvement because the display of eventuating forces is only in numbers, not yet including a test graph. Therefore, this study developed a prototype data acquisition system for a tensile test machine to record the test results in more detail, both numbers and graphs. This data acquisition system uses the Arduino Uno Microcontroller, which processes data from the load cell through the HX711 module intermediary. A tensile test was carried out using a bamboo fiber composite material to validate the results of testing the prototype of this data acquisition system. Furthermore, the test results data are compared with the results on the indicators of the existing tensile test machine. The test was carried out nine times with an average tensile force of 1.66 N/mm2, while the average tensile force on the tool indicator was 2.02 N/mm2. There is a difference in the average test results equal to 12%. This difference is a systematic error because nine experiments have shown the same trend, with standard error and standard deviation of 0.3368 and 0.1123, respectively. The systematic error is compensated through calibration between the load cell of the tensile test machine and a series of data acquisition systems based on Arduino Uno.

In vitro evaluation of drying supports and adhesive polymers as adjuvants for biocontrol of Diplodia seriata by Trichoderma harzianum and Clonostachys rosea
Authors: AGUIRRE Katherina , PEREZ Luz M. , MONTEALEGRE Jaime R.
Published: September 2023

Grapevine trunk diseases (GTDs) can cause large losses in vineyards. Diplodia seriata is an important GTD pathogen in Chile. Development and use of bioprotectors is a complementary alternative to the use of agrochemicals for disease management. To produce bioformulations for management of D. seriata, additives could be used to maintain viability and survival of biocontrol agents, such as Trichoderma harzianum and Clonostachys rosea. Effects of drying supports (inulin, maltodextrin, lactose, or talc) and adhesive polymers (carboxymethylcellulose, Aloe vera gel, or chitosan) were assessed on D. seriata conidium viability and mycelium development of T. harzianum and C. rosea, and for their biocontrol capacity against D. seriata. T. harzianum and C. rosea cultured in Potato Dextrose Agar containing inulin (at 10% w/v) maltodextrin (10% w/v), lactose (6% w/v), or talc (4% w/v), or the adhesive polymers carboxymethylcellulose (0.5% w/v), Aloe vera gel (0.5% w/v), or chitosan (1.5% w/v), maintained their biocontrol activity against D. seriata. These additives did not enhance D. seriata development. Therefore, these preparations, at the respective indicated concentrations, can be included in bioformulations for management of disease caused by this pathogen.

Good health of grapevine plants is important for productivity and sustainability of newly established vineyards, and accurate detection of bacterial and fungal pathogens is a prerequisite for managing the diseases they cause in nurseries. This study screened marketable, bare-rooted grapevine plants, obtained from different geographical regions of Türkiye, for fungal pathogens associated with grapevine trunk diseases (GTDs). In 2021, 43 grapevine nurseries located in eight provinces were surveyed to reveal the status of GTD pathogens on asymptomatic marketable plants. Fungal pathogens isolated from the roots and basal parts of asymptomatic dormant grapevines were identified using with morphological characteristics and molecular markers, and were subjected to pathogenicity tests. Six species; Cytospora viticola, Diaporthe ampelina, Diplodia seriata, Lasiodiplodia brasiliensis, Neofusicoccum parvum, and Truncatella angustata (associated with dieback), and six species; Cadophora ferruginea, Cadophora luteo-olivacea, Cadophora malorum, Phaeoacremonium minimum, Phaeoacremonium tuscanicum and Phaeomoniella chlamydospora (associated with Petri disease) were identified based on DNA sequencing of ITS and TEF1-α genes. GTD pathogens were detected in 12 and 14 of the 43 nurseries, respectively. Pathogenicity tests on 1103P vines revealed that all species were pathogenic (N. parvum and C. luteo-olivacea being the most virulent), and caused significant wood necroses when compared to non-inoculated experimental controls. This is the first report of C. ferruginea, C. malorum, L. brasiliensis, and P. tuscanicum associated with GTDs in Türkiye.
Unravelling the colonization mechanism of Lasiodiplodia brasiliensis in grapevine plants

Published: September 2023

Botryosphaeriaceae cause the degenerative disease Botryosphaeria dieback in many woody hosts, including grapevine. These pathogens penetrate host plants through pruning wounds, and colonize vascular tissues causing necrotic lesions, cankers, and eventually plant death. Colonization processes by Botryosphaeriaceae and their interactions with their hosts has been understudied. The colonization mechanisms were examined for Lasiodiplodia brasiliensis, a common pathogen causing Botryosphaeria dieback in Mexican vineyards. Lasiodiplodia brasiliensis MXBCL28 was inoculated onto grapevine ‘Cabernet Sauvignon’ plants, and after 2 months, infected tissues were observed with microscopy using histological techniques. Lasiodiplodia brasiliensis was also cultured on different carbon sources representing cell walls and non-structural plant components, to complement histology data. The host responded to wounding by developing xylem vessel occlusions with tyloses and deposition of suberin in cambium and ray parenchyma. Infection response also included deposition of suberin in pith tissues, reinforcement of cell walls with phenolic compounds, and lignin deposition in xylem vessels and ray parenchyma. The pathogen could overcome host compartmentalization mechanisms and colonize wood tissue causing extensive necrosis. The fungus was visualized in host cambium, vascular bundles, xylem vessels, and pith, and infected tissues were depleted in starch in the ray parenchyma. Cellulose, hemicellulose, and lignin in cell walls were also degraded, supporting in vitro data.
Virulence of Puccinia triticina and Puccinia tritici-duri on durum wheat in southern Spain, from 2020 to 2022

Published: September 2023

Leaf rust is a major wheat disease in southern Spain, where durum wheat is an important crop. Until the 2019/2020 season, this disease was effectively managed, as the most widely planted cultivars in southern Spain had effective resistance genes. A problem arose in the spring of 2020, when every farm field and durum wheat trial examined displayed leaf rust symptoms. Leaves had few but large uredinial pustules, different from those of the normal leaf rust caused by Puccinia triticina, and telia developed rapidly after only a few days. The symptoms clearly fitted with P. tritici-duri, another wheat leaf rust species already reported in the western Mediterranean Basin. This species is not new in southern Spain but has never been observed at such high severity on almost every durum wheat cultivar grown in that region. Leaf rust severity was assessed in durum wheat field trials in the 2020, 2021 and 2022 growing seasons in four provinces of southern Spain. During 2020 and 2021, 13 single pustule isolates of leaf rust were also collected from different cultivars of durum wheat. Inoculation of the isolates on a differential host set showed that four different races were present, two being of P. tritici-duri. Only cultivar Calero showed consistent resistance to the races of P. tritici-duri employed in this study.
Black foot in nursery grapevines in Uruguay caused by Dactylonectria and Ilyonectria
Authors: CARBONE María Julia , REYNA Rossana , MONDINO Pedro , ALANIZ Sandra
Published: September 2023

Black foot is a serious soilborne fungal disease causing decline of young grapevines. Affected plants show brown to dark streaks developing from the rootstock bases, wood necroses at trunk bases, sunken necrotic lesions on roots, and reduced root biomass. Several fungi, commonly known as Cylindrocarpon-like asexual morphs, have been associated with black foot. Nursery vines are infected during rooting in propagation processes, which is important for dissemination of the pathogens. Species associated with black foot in nursery vines produced in Uruguay were characterized by molecular, phenotypical and pathogenicity studies. From 2017 to 2019, 181 rooted vines grafted onto ‘1103P’, ‘SO4’, ‘101-14’, ‘3309C’ or ‘Gravesac’ rootstocks were sampled, and 71 Cylindrocarpon-like fungal isolates were recovered from rootstock tissues (basal ends and roots). Based on multi-gene phylogenetic analyses of HIS3, TEF and TUB2, and supported by phenotypical characterization, five species of Dactylonectria and Ilyonoectria were identified, with D. macrodidyma being the most prevalent followed by D. novozelandica, D. torresensis, D. palmicola and I. liriodendri. Four Ilyonectria isolates could not be identified to species level. Isolate pathogenicity was assessed using healthy rooted ‘Gravesac’ plants. After three months, isolates of all species infected the plants, causing necrotic lesions on roots and reducing root biomass. On average, 39% of ready-to-plant nursery vines were affected by black foot, emphasizing the need to develop integrated management to reduce black foot incidence in Uruguayan grapevine nurseries, based on studies under local conditions.

Published: September 2023

Grapevines require pruning procedures to maintain plant morphology and ensure productivity, and these procedures cause wounds that induce physical and biological host defence mechanisms. Grapevine tissue reactions to wounding resulting from four different pruning methods were assessed. Rapid (immediate) defence reactions were detected in 1-year-old canes with preserved basal buds. Formation of tyloses (≈ 90% of xylem vessels) was observed 1 month later on canes where the basal buds were maintained and no short stubs were left (i.e. the pruning cuts preserved the buds). At 2 months after pruning, lignin was slightly increased in cortical parenchyma after pruning of 3-year-old grapevine wood. Neither callose nor suberin production was observed in healing wounds, as is known in other fruit or broadleaf trees. In 3-year-old canes, fungal hyphae were observed in the non-active wood below the pruning cut surfaces. Preliminary observations of desiccation cones within canes confirmed that the basal buds preserved the canes from desiccation, after comparing different pruning procedures on canes of the same age. After 9 months, the desiccation cones were greater in 3- than 1-year-old wounds.
Potential role of Fusarium spp. in grapevine decline

Published: September 2023

Despite studies associating Fusarium spp. with grapevine decline since late 1970s, no consensus has been reached regarding the roles these fungi play in grapevine health. Recent studies in British Columbia, Canada, assessed prevalence of grapevine trunk diseases (GTDs) in young and mature vineyards, and the presence of GTD fungi in ready-to-plant nursery material sold in Canada. This study characterized the Fusarium spp. isolated from grapevines in BC by sequencing part of the translation elongation factor 1-alpha (TEF1) gene, and carried out pathogenicity studies to determine whether Fusarium plays a role in grapevine decline. Fusarium spp. were isolated from 9.8% of samples collected from young vines (≤ 8-year-old), and 7.3% from mature vines (> 8-year-old), showing decline symptoms in commercial vineyards. Fusarium was also isolated from 43.9% of ready-to-plant dormant grapevines analyzed from four nurseries. Fusarium incidence varied between plants within the same nursery and between plants from the different nurseries. DNA sequences of TEF1 allowed identification of Fusarium oxysporum, F. proliferatum, F. ramigenum, and a Fusarium sp. Pathogenicity studies were conducted in 1-year-old dormant rooted ‘Chardonnay’ plants grafted onto ‘3309C’ rootstock, and treatments included: i) whole plant, ii) trimming of roots, iii) cut at rootstock basal ends, and iv) trimming of roots plus cut at rootstock basal ends. Plants were inoculated using standardized methods, and were then planted in a greenhouse. Fusarium was compared with Dactylonectria macrodidyma, D. pauciseptata and Ilyonectria liriodendri used as positive controls. The Fusarium spp. caused necroses in rootstock roots and basal ends that were similar to those caused by black-foot fungi. Fusarium spp. and black-foot fungi reduced root and shoot dry weights when compared with non-inoculated controls, but no statistically significant differences were recorded for most treatments. This study is the first in Canada to identify Fusarium spp. from grapevines. Though Fusarium was common in these grapevines, pathogenicity tests suggest that the identified Fusarium spp. were weakly pathogenic to ‘3309C’ rootstock grapevines.

Método: estudo qualitativo, realizado no período de outubro de 2021 a fevereiro de 2022, a partir de 20 entrevistas com profissionais de diferentes serviços da rede de atenção à saúde e de assistência e desenvolvimento social de um interior paulista, por meio da análise temática, utilizando-se da ferramenta NVivo. Resultados: foram identificados os temas: a situação de viver na rua favorece o uso de álcool e outras drogas; incipiente efetivação da Rede de Atenção Psicossocial (RAPS); incipiente efetivação da Política de Redução de Danos e Influência do terceiro setor no cuidado à PSR. Considerações Finais: Evidenciam-se limites para a promoção do cuidado na perspectiva da atenção psicossocial, sendo que para avançar é necessário dar voz e considerar as especificidades da PSR, compreender suas concepções do processo de saúde-doença e suas trajetórias.

Dentre os princípios norteadores do Sistema Único de Saúde (SUS), a integralidade é um dos mais importantes, porém sua operacionalização tem se demonstrado um desafio complexo para a efetiva consolidação SUS. Nesse sentido, no que tange à formação dos profissionais de saúde, as Diretrizes Curriculares Nacionais apontam a necessidade de adequação curricular das áreas da saúde. Objetivo: Analisar a compreensão e a prática de fisioterapeutas que atuam na Atenção Primária à Saúde de um município do interior do Estado de São Paulo, Brasil, sobre o cuidado na perspectiva da integralidade. Métodos: Pesquisa de campo, de abordagem qualiquantitativa baseada na Teoria das Representações Sociais. Participaram 15 fisioterapeuta, cujos dados foram obtidos a partir de quatro perguntas abertas. Emergiram 15 ideias centrais distribuídas em quatro quadros representativos das ideias centrais e discursos do sujeito coletivo; neste estudo, serão apresentados os resultados e discussões referentes à prática do cuidado destes profissionais na perspectiva da integralidade. Resultados: O estudo constatou que os fisioterapeutas da APS realizam sua assistência na perspectiva da integralidade em seu dia a dia, privilegiando a escuta ativa e valorizando não só os sintomas físicos, mas também os emocionais. Além disso, desenvolvem a integralidade do cuidado a partir da promoção da autonomia dos pacientes, valorizando a escuta ampliada, ou seja, ativa. Considerações finais: Os fisioterapeutas têm práticas de cuidado voltadas à integralidade da população; entretanto,  embora haja um movimento de transformação, ainda é necessário avançar na formação dos profissionais e na divulgação das reflexões sobre a temática para melhorar a assistência fisioterapêutica, conforme preconizado pelo SUS e as DCN.

El estudio organizacional crítico se enfoca en el reconocimiento, análisis y comprensión de la diversidad de las realidades locales que dan vida a las organizaciones. La complejidad que conlleva este abordaje integral vuelve necesaria la integración de metodologías de orden cualitativo que permitan un acercamiento genuino a las fuentes de información primarias. La historia de vida, como método de investigación, permite reconocer las experiencias subjetivas de los actores clave y del propio investigador; a través de las cuales se puede acceder a recuerdos, concepciones, ideologías, entre otros elementos que dan cuenta de conocimientos únicos a los que difícilmente se podría tener acceso por medio de métodos positivistas. Objetivo. En ese sentido, el objetivo del trabajo es reflexionar sobre los fundamentos de la historia de vida como método de investigación cualitativa y su alcance para el análisis organizacional crítico. Método. Se realizó un análisis de documentos teórico para recuperar las principales características del análisis organizacional y de los alcances de la historia de vida como método de investigación. Esto se complementa con una revisión de tesis del doctorado en Estudios Organizacionales, que utilizan historia de vida en su metodología. Resultados. Los resultados muestran que la historia de vida, como método de investigación, presenta diversas bondades que contribuyen al análisis organizacional. Sin embargo, a pesar de ello, se ha retomado más como una herramienta de recolección de la información que como un método de investigación. Conclusiones. Ante ello, se concluye que resulta necesario ahondar sobre la discusión de las bondades que la historia de vida ofrece como método de investigación, especialmente para la generación de conocimiento organizacional desde un enfoque crítico.

Published: September 2023

Los efectos del SARS-CoV-2 transformaron la cotidianeidad de jóvenes universitarios pertenecientes a la Universidad Nacional Agraria La Molina, en Lima, Perú. En este escenario, algunos docentes consideraron necesario conocer estos efectos a fin de proponer respuestas que mejoren su inclusión en esta nueva etapa de su vida académica.  El estudio propuso analizar cómo sus dinámicas familiares y académicas fueron alteradas por las intervenciones gubernamentales impuestas al inicio de la pandemia. Frente a contextos familiares diversos en la ciudad de Lima (y otras partes del Perú), cada joven tuvo que enfrentar un proceso de adaptación a la vida familiar y académica, de acuerdo a sus posibilidades. Se parte de un estudio cualitativo exploratorio, llevándose a cabo grupos focales que recopilaron información sobre las alteraciones en sus dinámicas familiares y académicas. De los resultados obtenidos destacan que la mayor parte de los entrevistados sufrieron altos niveles de estrés, siendo el “estrés académico” el elemento de mayor relevancia identificado. Los entrevistados relatan que los múltiples estresores identificados influenciaron su toma de decisiones, afectando directamente su estancia en la propia universidad, donde la de deserción de estudios fue considerada como una opción. En contraparte, se priorizaron las (nuevas) dinámicas familiares producto de la pandemia, en algunos casos en detrimento de su bienestar académico.

La satisfacción del cliente es determinante en el éxito empresarial debido a factores como la entrada de nuevos productos compatibles, la facilidad de acceso a la información, las demandas de los compradores, la elasticidad de la demanda y la creciente preocupación de los consumidores por temas como la salud y el cuidado del medio ambiente. El propósito de este manuscrito es evaluar los factores incidentes en la satisfacción del cliente desde un enfoque teórico con evidencia empírica a partir de postulados sobre la medición de la satisfacción y calidad del servicio al cliente. El método sigue un estudio concluyente con un enfoque cuantitativo y transversal. La recolección de información primaria se realizó mediante un instrumento estructurado y validado que se administró en tres ciudades de Colombia. Se utilizó la estadística descriptiva para la triangulación de datos a través de los programas Excel y SPSS. Se estima que los factores que inciden en la satisfacción del cliente se enfocan en aspectos como capacidad instalada, infraestructura, implementación de medidas sanitarias, atención al cliente y filosofía institucional. Asimismo, se concluye que es necesario implementar mecanismos de medición de la satisfacción del cliente, los cuales deben adaptarse a la cultura de cada región, las necesidades de los clientes y las características de los supermercados.

Published: September 2023

El crecimiento de las economías del mundo se ha sustentado en un modelo de producción de carácter lineal, lo que ha implicado un proceso de degradación paulatina de los recursos naturales, hoy en día, los esfuerzos por modificar la manera de generar los bienes y servicios son nimios, la ausencia de una cultura empresarial sustentable, de un consumo responsable de la ciudadanía, la falta de políticas públicas protectoras del medio ambiente de los gobiernos, contribuyen a que la amenaza de la insustentabilidad siga latente. La economía circular es el modelo alternativo que puede modificar disruptivamente el proceso productivo, por ello, en aras de evidenciar las ventajas de circularizar la economía, se establece el siguiente objetivo; identificar la incidencia potencial de la economía Circular en el logro de los objetivos de desarrollo sostenibles del plan 2030 de las Naciones Unidas, patentizando la oportunidad de la sinergia social. Para lograrlo, se utilizó un análisis teórico-empírico con un carácter exploratorio a partir de la selección-cribaje de documentos y aplicación de encuestas a un grupo de informantes clave. Los principales resultados arrojan que existen puntos de encuentro entre la economía circular y los objetivos de desarrollo sostenible 7, 8, 9, 10, y 12, de los 17 declarados, además resalta la necesidad de unir esfuerzos por parte de los diferentes sectores de la sociedad, empresarios, consumidores y gobernantes, para garantizar un desarrollo económico sustentable.
Entrepreneurship in Latin America: Perspectives for a new world order
Authors: Montiel Mendez Oscar Javier , Muzzio Henrique
Published: September 2023

The unipolar world has disappeared. There is a new, emerging multipolar system that confronts the established values of the last century, which influences the cultural, social, and economic spaces throughout the world. In the latter, changes in the dominant currency, economic blocks and trade agreements, logistics, offshoring versus nearshoring, bank collapses, inflation, and high-interest rates are confronting entrepreneurship all over the world, especially in the Global South. Our article, after a personal reflexivity analysis, is an invitation to open debates on the multiple risks but also opportunities this new geopolitical world order is having for Latin America and how the future might evolve on it and in related areas, in terms of how the many elements of its so-called entrepreneurial ecosystem (entrepreneur, universities, public policies in the micro, maso and macro levels, cultural and institutional obstacles/advantages, gender related themes, social initiatives, and SME s and large/global firms, and the different helixes) are/will face this emerging challenges.
