Technology-mediated affective socialization processes in the dating app Tinder are analyzed. The research was qualitative, exploratory and descriptive, of 200 profiles and 50 semi-structured interviews with male users, aged 36 to 55 years, residing in Monterrey (Mexico). Among the results, tendencies were found towards simultaneous and intermittent interaction with multiple profiles, competition through the game and a progressive socialization for the establishment of online sex practices. It is concluded that the Tinder application promotes communication based on an instrumentalist ethic that persuades the user towards a lack of transparency and honesty, as well as the objectification of interlocutors and affective relationships.

Temperature generated by AuNPs when irradiated with laser, was evaluated to determine their usefulness in photonic plasmonic photothermal therapy or multiphotonic plasmonic photothermal therapy respectively. AuNPs were synthesized by the Turkevitch method and characterized by spectroscopic techniques. The AuNPs were irradiated by a Nd:YAG laser for 210 s, with 532 and 1 064 nm wavelength at 5, 10 and 15 Hz pulse repetition rate frequency. Temperature recording was carried out every second by a type-K thermocouple bounded to an Arduino UNO® card. AuNPs showed spherical shape, size of 20.7 + 0.2 nm and a maximum absorption peak of 520.16 + 0.93 nm. Irradiation at 1 064 nm exhibits higher temperature increase by 3.4, 1.9, and 1.2 times more than at 532 nm at the respective frequencies.

This paper seeks to reflect on poverty and economic inclusion in a specific sector; the LGBTI+ community. The analysis is based on the United Nations Development Programme and the World Bank’s LGBTI Inclusion Index. By means of a theoretical reflection, as well as a field study in the Guadalajara Metropolitan Area, the aim is to identify the impact that inclusion can have on the lack of opportunities and poverty of this group in productive age. As a conclusion it is confirmed that the lack of inclusion is a factor that can detonate poverty in a population of this group. 

The present article reviews the current state of production of microorganisms as a source of nutrients, with emphasis on microbial groups such as yeasts, bacteria, cyanobacteria and microalgae, which show a high potential for their massive production. Many microorganisms can be a source of nutritious, sustainable ingredients for both, human populations and livestock. Food items derived from fisheries and agriculture have an important role in satisfying the current human population needs. However, it is forecast that the growth of these industries will be restricted due to overfishing and unavailability of arable land. Among the alternative sources of nutrients, the biomass produced from several microbial sources has been considered a promising substitute for the proteins currently supplied by plants and animals.

Los rendimientos del algodón en el Ecuador son bajos, una de las causas es la falta de material genético y de tecnologías de producción. Por esta razón, el Instituto Nacional de Investigaciones Agropecuarias del Ecuador introdujo desde Brasil la variedad BRS-336. En este experimento de campo se probó el rendimiento de esta nueva variedad bajo manejo agronómico local. Los factores evaluados fueron la densidad de plantas (62 500 y 50 000 plantas ha-1), variedades de algodón (DP-Acala 90 y BRS-336) y programas de manejo de cultivos (tecnología INIAP y tecnología convencional), dispuestos en un Diseño de Parcela Subdividida, con cuatro repeticiones. Las variables evaluadas fueron: incidencia de artrópodos plaga y presencia de enemigos naturales, incidencia de enfermedades, porcentaje de germinación, altura de planta y longitud de los entrenudos (cm), número de ramas productivas por planta, días para la apertura de la primera flor y bellota, número de bellotas por planta, peso y rendimiento del algodón en rama (kg ha-1). La variedad introducida BRS-336, se comportó de manera similar en aspectos agronómicos y de productividad, a la variedad local DP-Acala 90. La utilización del programa de manejo de cultivos con la tecnología del INIAP fue determinante para aumentar el rendimiento.

Today, countries around the world attach special importance to "entrepreneurship" as a vital factor of stability and economic growth. Entrepreneurship is one of the main factors in creating economic value and an effective tool to reduce unemployment. Entrepreneurship education and training in developed countries is a significant part of the education programs of schools, universities, organizations and institutions. The task of secondary education is to prepare young people to choose the paths of life and to shape these paths in order to accept responsibilities in the future. Therefore, the present study has tried to collect information from various documents and sources based on the evaluation of the current curriculum from the perspective of relevant groups (specialists, teachers and students) to design the optimal model Entrepreneurship and Production curriculum (EPC) based on the main elements of the curriculum (objectives, content, learning activities and evaluation). In addition, in order to validate the designed model, it was provided to the curriculum specialists and educational staff, and finally, it presented the designed model along with suggestions and solutions. This research is applied from the perspective of purpose and is of evaluation type and the method of conducting it is field research. The statistical population of the study includes curriculum specialists in the field of entrepreneurship, all teachers working to teach entrepreneurship and production and all students studying in the second year of high school in Ahvaz city in the academic year 2020-2021. Sampling of specialists by purposive sampling method by selecting 14 people as a sample and in the group of teachers by simple random method and by selecting 89 teachers and in the group of students using Cochran's formula by stratified random sampling method, and it was done by selecting 300 people. Data collection tool was a researcher-made questionnaire that was redesigned using semi-structured interviews and descriptive statistics, and inferential statistics (Chi-square) were used to analyze the data. Statistically, there is a difference between the opinions of the study groups in the element of objectives, content, learning activities and evaluation of the current EPC of the second secondary school. Therefore, based on the results of evaluation and semi-structured interviews with experts and teachers, the proposed model has been designed.

The unemployment of people in the Amazonian communities of Ecuador has increased during the pandemic caused by the Covid-19 disease, mainly from March to August 2020; so, the population has turned its attention to the agricultural sector. This economic sector is specifically directed towards the overexploitation of timber resources and the hunting of animals. This study proposes an Environmental Management Plan for three agricultural farms located in the San Pablo de Ushpayaco parish, Napo, Ecuador, which sell mostly organic products in local markets. The fieldwork included a historical analysis of the sector, the diagnosis of survival strategies, relevant environmental aspects, identification of actors and interests regarding access to resources. As a result of the research, problems of inefficient use of water resources, poor management of land use due to its overexploitation through monoculture practices, absence of practices for sustainable agriculture and livestock, poor crop rotation, low application of organic fertilizers, lack of inputs and resources. Poor agricultural practices have led to low production yields and limited economic profit for farmers. This Environmental Management Plan focuses on the prevention, mitigation, and compensation of the environmental impacts caused by agriculture and thus improving the communities' quality of life in the study case.
