Knowledge and Perception of the Present Moment and Emotions
Because emotional intelligence (EI) relies on one’s own awareness of emotions, it may be helpful to see if there is a relationship with mindfulness. Previous research has measured both constructs using self-report measures and suggests that there is a positive relationship between them. However, a drawback of self-report measures of EI is that individuals may not be able to accurately report on their abilities. In contrast to self-report measures, other researchers have argued that behavioral measures better capture ability of EI. Therefore, this study will replicate previous research that examined the relationship between mindfulness and EI by administering a self-report measure of both constructs, and build upon this research by utilizing behavioral measures of EI. Specifically, this study will be looking at undergraduate students and observing whether students with higher mindfulness will have higher levels of self-reported EI and perform better on behavioral measures of EI
Hydrothermal multivariable approach. Full-scale feasibility study
A process configuration combining thermal hydrolysis (TH) and anaerobic digestion (AD) of sludge has been studied with the objective of analysing the feasibility of the technology for full scale installations. The study has been performed through pilot scale experiments and energy integration considerations, and a scheme of the most profitable option is presented: thermal hydrolysis unit fed with 7% total solids (TS) secondary sludge, anaerobic digestion of the hydrolysed sludge together with fresh primary sludge, and a cogeneration unit to produce green electricity and provide hot steam for the thermal hydrolysis process. From a technical and practical point of view, the process scheme proposed is considered to be feasible. Based on the results of the pilot plant performance and the laboratory studies, the process has proven to operate successfully at a concentration of 7-8% TS. After the thermal hydrolysis, sludge viscosity becomes radically smaller, and this favours the digesters mixing and performance (40% more biogas can be obtained in nearly half the residence time compared to the conventional digestion). From an economic point of view, the key factors in the energy balance are: the recovery of heat from hot streams, and the concentration of sludge. The article presents the main energy integration schemes and defines the most profitable one: an energetically self-sufficient process, with a cogeneration unit. The scheme proposed has proven to need no additional energy input for the sludge hydrolysis, generates more that 1 MW green electricity (246 kW surplus with respect to the conventional process), and produces 58% less volume of Class A biowaste. The study and balances here presented set the basis for the scale-up to a demonstration plant (hydrolysis + anaerobic digestion + cogeneration unit)
Niveles De Motivación Y Las Competencias Laborales Específicas De Los Trabajadores A Distancia
The aim of this study was to determine the relationship between motivation and specific job skills of teleworkers. The methodology was applied, descriptive and correlational. The study was hypothetical deductive, non experimental, transactional and quantitative. The sampling was non probabilistic by quotas, was included telecommuters from different companies that use this type of work, located in the interior of Mexico, USA and Canada. The sample size was 27 teleworkers. A questionnaire of 52 questions was used as a measuring tool. The data analysis was descriptive and chi square test was used to identify the relationship of the independent variable motivation with the dependent variable specific job skills of teleworkers. The main results showed that motivation is high and teleworkers have a high development in most of their job skills. Also among the most outstanding results it was found that the variable motivation in the three indicators analyzed: the need for existence, value and growth, have a closer relationship with labor competition autonomy, than the rest of labor skills analyzed

Improving SWAT model performance in the upper Blue Nile Basin using meteorological data integration and subcatchment discretization
The Blue Nile Basin is confronted by land degradation problems, insufficient agricultural production, and a limited number of developed energy sources. Hydrological models provide useful tools to better understand such complex systems and improve water resources and land management practices. In this study, SWAT was used to model the hydrological processes in the upper Blue Nile Basin. Comparisons between a Climate Forecast System Reanalysis (CFSR) and a conventional ground weather dataset were done under two sub-basin discretization levels (30 and 87 sub-basins) to create an integrated dataset to improve the spatial and temporal limitations of both datasets. A SWAT error index (SEI) was also proposed to compare the reliability of the models under different discretization levels and weather datasets. This index offers an assessment of the model quality based on precipitation and evapotranspiration. SEI demonstrates to be a reliable additional and useful method to measure the level of error of SWAT. The results showed the discrepancies of using different weather datasets with different sub-basin discretization levels. Datasets under 30 sub-basins achieved Nash-Sutcliffe coefficient (NS) values of -0.51, 0.74, and 0.84;p factors of 0.53, 0.66, and 0.70;and r factors of 1.11, 0.83, and 0.67 for the CFSR, ground, and integrated datasets, respectively. Meanwhile, models under 87 sub-basins achieved NS values of 1.54, 0.43, and 0.80;p factors of 0.36, 0.67, and 0.77;r factors of 0.93, 0.68, and 0.54 for the CFSR, ground, and integrated datasets, respectively. Based on the obtained statistical results, the integrated dataset provides a better model of the upper Blue Nile Basin
Legacies of past forest management determine current responses to severe drought events of conifer species in the Romanian Carpathians
Worldwide increases in droughts- and heat-waves-associated tree mortality events are destabilizing the future of many forests and the ecosystem services they provide. Along with climate, understanding the impact of the legacies of past forest management is key to better explain current responses of different tree species to climate change. We studied tree mortality events that peaked in 2012 affecting one native (silver fir; growing within its natural distribution range) and two introduced (black pine and Scots; growing outside their natural distribution range) conifer species from the Romanian Carpathians. The three conifers were compared in terms of mortality events, growth trends, growth resilience to severe drought events, climate-growth relationships, and regeneration patterns. The mortality rates of the three species were found to be associated with severe drought events. Nevertheless, the native silver fir seems to undergo a self-thinning process, while the future of the remaining living black pine and Scots pine trees is uncertain as they register significant negative growth trends. Overall, the native silver fir showed a higher resilience to severe drought events than the two introduced pine species. Furthermore, and unlike the native silver fir, black pine and Scots pine species do not successfully regenerate. A high diversity of native broadleaf species sprouts and develops instead under them suggesting that we might be witnessing a process of ecological succession, with broadleaves recovering their habitats. As native species seem to perform better in terms of resilience and regeneration than introduced species, the overall effect of the black pine and Scots pine mortality might be compensated. Legacies of past forest management should be taken into account in order to better understand current responses of different tree species to ongoing climate change. © 2020 Elsevier B.V.We thank the Forest District staff of Sacele, Kronstadt, Rasnov, Teliu, Codlea, and Intorsura Buzaului for all their support and for giving us access to the Forest Management Plans.

La investigación participativa en niños como herramienta en la promoción de la salud para la prevención de la Enfermedad de Chagas en Yucatán, México
Introducción: La Investigación Participativa (IP) es una herramienta que puede abordarse para el análisis de procesos socioculturales, medioambientales, y de salud pública. La participación de niños en edad escolar en la apropiación del conocimiento para la prevención de la Enfermedad de Chagas (EC) puede romper su ciclo de transmisión. La EC es un problema de salud pública que afecta principalmente a comunidades rurales endémicas de países en desarrollo. Objetivo: Desarrollar una estrategia para la adquisición y transferencia de nuevos conocimientos en niños, debido en la falta de información acerca del ciclo de transmisión de la Enfermedad de Chagas. Material y Métodos: Estudio observacional de corte transversal, realizado con un grupo de 48 niños de una comunidad en pobreza extrema en Yucatán, México. Mediante herramientas de IP y con el apoyo de padres de familia, autoridades ejidales y escolares, se impartieron talleres educativos a niños en la escuela de educación básica para conocer el ciclo de transmisión, y prevenir la EC debido a la abundancia del vector en el área de estudio. Se implementó un programa denominado “Pequeños Investigadores”, para iniciar procesos de apropiación y socialización del conocimiento en la comunidad. Resultados: El nuevo conocimiento adquirido por el grupo de niños fue aprovechado y diseminado a sus familias, compañeros de escuela, y círculos sociales, fomentando la prevención de la enfermedad. Fueron recolectados 182 triatomas a nivel domiciliar y peri domiciliar. Conclusiones: Los nuevos conocimientos, actitudes y prácticas adquiridos por los niños bajo esquemas de participación, resulta benéfico para la prevención de la EC. Se recomienda al sector oficial la participación en la promoción de la salud en niños bajo el esquema del presente estudio en países en desarrollo.

ABSTRACT
INTRODUCTION: Participatory Research (PR) is a tool that can be approached for the analysis of sociocultural, environmental, and public health processes. The participation of school-age childrens in the appropriation of knowledge for the prevention of Chagas' Disease (CD) can break the cycle of transmission. CD is a public health problem that mainly affects rural endemic communities of developing countries. METHODS: A cross-sectional study was carried out with a group of 48 childrens from a community in extreme poverty in Yucatan, Mexico. Through PR tools and with the support of parents, ejidal and school authorities, educational workshops were given to children of the basic education to know the cycle of transmission, and to prevent CD due to the abundance of the vector in the study area. A program called "Small Investigators" was implemented to initiate processes of appropriation and socialization of knowledge in the community. RESULTS: The new knowledge acquired by the group of children was used and disseminated to their families, partners, and social circles, promoting the prevention of the disease. 182 triatomas were collected at home and peri domicile. CONCLUSIONS: The new knowledge, attitudes and practices acquired by children under participation schemes is beneficial for the prevention of the Chagas Disease. The official sector is recommended to design the promotion health programs in children under the scheme of the present study in developing countries.

Knowledge Integration and Diffusion: Measures and Mapping of Diversity and Coherence
I present a framework based on the concepts of diversity and coherence for
the analysis of knowledge integration and diffusion. Visualisations that help
understand insights gained are also introduced. The key novelty offered by this
framework compared to previous approaches is the inclusion of cognitive
distance (or proximity) between the categories that characterise the body of
knowledge under study. I briefly discuss the different methods to map the
cognitive dimension
How to Be Unfaithful to Eurocentrism: A Spanglish Decolonial Critique to Knowledge Gentrification, Captivity and Storycide in Qualitative Research
From a position of academic activism, we critique the longstanding dominance del production of knowledge that solely implicates fidelity to Eurocentric methodological technologies en qualitative research. Influenced by an Andean decolonial perspective, en Spanglish we problematize métodos of analysis as the dominant research practice, whereby las stories o relatos result en su appropriation, captivity and gentrification, first by researchers’ authorship and later by the publishing industry copyrights. We highlight the racializing and capitalist colonial/modern Eurocentric agenda del current market of knowledge production that displaces to la periphery all knowledge o relatos that do not subscribe to Euro-US American methodological parameters of what counts as knowledge. Therefore, we intend to heighten the readers’ audibility of another possibility of knowing that does not come from Eurocentric methodologically produced stories. At the forefront of our critique, and as an introduction to a decolonial option, we include our written, uttered, and painted stories, with the political intent of social transformation of coloniality. These seek to denounce power structures that have had incarnated effects on our lives y comunidades. We intend to invite researchers to serve as witnesses of our experiences rather than as critics of methodological rigor. We include final commentaries on a decolonial project to rethink the unquestionable fidelity and dependency toward the current research order of things of el center and la periphery. This is so as to render European technologies of knowledge as only one alternative among many other possible means of legitimate knowledge making in qualitative research. We discuss our hope for epistemological coexistence by which fair and reciprocal intercultural translations of knowledge making could take place, not in the name of equality, but difference
