Este trabajo surge a partir de la investigación general de las técnicas hidropónicas teniendo en cuenta sus ventajas y desventajas para de esta forma poder encontrar aquel factor determinante a través de una comparación de técnicas hidropónicas que permitan clasificarlas y escoger la mejor opción que genere menos impacto ambiental negativo y demuestre ser más productivo en los entornos urbanos. Adicionalmente, un factor determinante en las ciudades es su espacio limitado por lo que la mejor opción también deberá incluir un (...) óptimo manejo del espacio que permita a casi cualquier individuo poder aplicarlos desde su entorno sin recurrir a excesivas modificaciones. Como principal resultado se escogió a la Hidroponía recirculante como método predominante por los excelentes resultados que se obtienen con relación a los demás, adicionalmente, este puede ser fácilmente aplicado en los ambientes urbanos por su versatilidad y buen manejo de recursos.

The paper has been written from a philosophical perspective and triggered by the recurrent discussions in psychology about the most suitable methods to study our multifaceted subjectivity. Its main point is that a phenomenological understanding of the human person provides a robust and also flexible philosophical framework for psychology. The first part discusses three classical distinctions –individual/general; explaining/understanding; induction/interpretation– which, in spite of possible deficiencies, are useful to illustrate the specificity of the human sciences relative to the natural sciences. If (...) not understood as an either-or dichotomy these distinctions represent the search of the right balance to reflect the complexity and richness of psychological science. The second part presents the phenomenological notions of ‘vital reduction’ and ‘personalist reduction’, where reductions does not take on an eliminativistic meaning, but of directing the mind’s gaze to attend to what is originally the case. The ‘vital reduction’ reveals a subject of experience at the center of the lifeworld, and the ‘personalist reduction’ sees in rationality –i.e., the power to grasp the meaning of things and to recognize other subjects of experience­– a deeper dimension of the subject, who we can thus call a person. Psychology and phenomenology converge in disclosing the person-centeredness of our lifeworld. (shrink)

El trabajo tiene como objetivo averiguar si para Tomás de Aquino el peccatum naturae consiste únicamente en la privación de la gracia sobrenatural, es decir en un estado en el que la naturaleza humana carece de la gracia divina pero no presenta una debilidad en relación a sus propias fuerzas morales naturales, consistentes en la capacidad de obrar según la razón. El tema está en el límite entre lo teológico y lo filosófico, pero cómo se lo resuelva impacta llanamente en (...) la comprensión filosófica del hombre y de su condición moral. De la revelación cristiana sobre los orígenes de la historia humana no se sigue una lectura ingenuamente optimista ni una irremediablemente pesimista. (shrink)

Rosmini’s philosophy is a comprehensive effort toward the renovation of Christian thought in modern times. An intense discussion of the problem of knowledge led him to reformulate Augustine’s theory of illumination in terms of the ideal presence of universal being to the mind. Universal being is the lumen intellectus and our mind’s first object: it is implied in all our thoughts and makes them possible. Although devoid of reality, it shows remarkable features, such as infinity, necessity, and eternity. Without being (...) God, it may be called “divine,” and confers a special value to intelligent creatures, whose dignity comes from their being enlightened by universal being. The “divine” is also the seal of God’s presence in nature. The present article supports the logic of this argument. (shrink)

In this work we review the three principal theses that Ignatio Vincentio, a Spanish thinker of the seventeenth century, defends about the agent intellect: 1) it is the same potency as the possible intellect, only with a formal distinction and plurality of names; 2) it has three tasks: a) to illuminate phantasmata, b) to make them intelligible in act, and c) to abstract the intelligible species from them; and 3) it will remain in the separated soul performing the same task (...) as in the present situation [?], but without conversion to phantasmata.

The debate over judicial review of legislation is profuse. But differences are often due to the lack of a common methodology. This article discusses the proper way to evaluate judicial review and confronts central challenges raised against it. It develops the two main models that can be used for analyzing the intersection between democracy and constitutional decision-making and shows that judicial oversight may not be rejected, regardless of how we interpret that connection. The article discusses in detail the model developed (...) by Jeremy Waldron. A nice attempt to answer methodological questions, Waldron's model wrongly tips the balance against judicial review. Its excessive level of abstraction and idealization renders it inoperable. Few systems meet its standards, and those that do pay a high price: they contradict the concept of democratic legitimacy that underlies the model. Paradoxically, a system with judicial review may end up being more legitimate than one without it. (shrink)

COVID-19 has resulted in extraordinary disruptions to the higher education landscape. Here, we provide a brief report on 295 students’ academic perceptions and emotional well-being in late May 2020. Students reported the high levels of uncertainty regarding their academic futures as well as significant levels of stress and difficulty coping with COVID-19 disruptions. These outcomes were related to the higher levels of neuroticism and an external locus of control. Female students reported worse emotional well-being compared to males, and the students (...) of color reported the significantly higher levels of stress and uncertainty regarding their academic futures compared to White students. These results suggest that some students may be at particular risk for academic stress and poor emotional well-being due to the pandemic and highlight the urgent need for intervention and prevention strategies.

According to kin selection theory, indirect reproductive advantages may induce individuals to care for others with whom they share genes by common descent, and the amount of care, including self-sacrifice, will increase with the proportion of genes shared. Twins represent a natural situation in which this hypothesis can be tested. Twin pairs experience the same early environment because they were born and raised at the same time and in the same family but their genetic relatedness differs depending on zygosity. We (...) compared the degree of willingness to fight and sacrifice for the co-twin among monozygotic and dizygotic pairs in a sample of 1443 same-sex and opposite-sex twins. We also analyzed the effect of the subject’s gender and that of the co-twin on those altruistic behaviors. Results partly supported the postulated explanation. MZ twins were significantly more likely than DZ twins to self-sacrifice for their co-twins, but zygosity did not affect willingness to fight for him/her. The genders of the subject and of the co-twin, not genetic relatedness, were the best predictors of aggressive altruistic intentions. (shrink)

Technical and tactical actions are decisive in terms of badminton player competitive performance. The main objective of this research was to design, validate, and estimate the reliability of an observational instrument for the analysis of the tactical and technical actions in individual badminton. The process was carried out in four different steps: first, there was a review of the scientific literature and a preliminary list of variables was made; second, a qualitative and quantitative assessment was completed by 10 badminton expert (...) judges; in the third step, the content validity was estimated using Aiken’s V coefficient; finally, intra-observer reliability and interobserver reliability were tested by two observers specialized in badminton using the Cohen’s Kappa coefficient and the intraclass correlation coefficient. Strokes were used as the unit of measure by our observational instrument; every time badminton players hit the shuttlecock, 22 variables are observed. The minimum Aiken’s value was 0.58, and reliability was 0.63. In spite of these values, none of the variables had to be removed, but there were modifications in terms of drafting in some of them. The main findings confirmed the validity and the usefulness of this instrument. (shrink)

BackgroundDistorted gambling-related cognitions are tightly related to gambling problems, and are one of the main targets of treatment for disordered gambling, but their etiology remains uncertain. Although folk wisdom and some theoretical approaches have linked them to lower domain-general reasoning abilities, evidence regarding that relationship remains unconvincing.MethodIn the present cross-sectional study, the relationship between probabilistic/abstract reasoning, as measured by the Berlin Numeracy Test, and the Matrices Test, respectively, and the five dimensions of the Gambling-Related Cognitions Scale, was tested in a (...) sample of 77 patients with gambling disorder and 58 individuals without gambling problems.Results and interpretationNeither BNT nor matrices scores were significantly related to gambling-related cognitions, according to frequentist analyses, performed both considering and disregarding group in the models. Correlation Bayesian analyses largely supported the null hypothesis, i.e., the absence of relationships between the measures of interest. This pattern or results reinforces the idea that distorted cognitions do not originate in a general lack of understanding of probability or low fluid intelligence, but probably result from motivated reasoning.

The counterfactual thinking cannot be only developed in early childhood, but it also could be a requirement for the causal reasoning. In this research a replica of German was made using counterfactual stories with Latin American kids between three and four years, demonstrating the possible main role counterfactual reasoning, by using computer animations. This was a different approach to the most recent made by Nyhout and Ganea. Nonetheless, the participants of the study evidenced counterfactual reasoning to the relevant choice and (...) the negative consequence conditions shown on the stories that represented the choices made by a starting role. Although some of the results were not totally conclusive under the analyzed conditions. Lastly, some possible not controlled effects are discussed from stories shown to the children, that could have motivated the counterfactual thinking. (shrink)

Automatic public malware analysis services provide controlled, isolated and virtual environments to analyse malicious software samples. Unfortunately, malware is currently incorporating techniques to recognize execution onto a virtual or sandbox environment; when an analysis environment is detected, malware behaves as a benign application or even shows no activity. In this work, we present an empirical study and characterization of automatic PMAS, considering 26 different services. We also show a set of features that allow to easily fingerprint these services as analysis (...) environments; the lower the unlikeability of these features, the easier for us to fingerprint the analysis service they belong to. Finally, we propose a method for these analysis services to counter or at least mitigate our proposal. (shrink)

In this article, we study Latin American populist constitutions and their uses, seeking to analytically understand whether populist constitutionalism is, indeed, a thing. We posit that Latin American populist constitutionalism is a particular form of mixed constitutionalism in three senses: first, as a specific combination of substantive traits that includes both empowering and constraining devices; second, as a peculiar politics of constitutional change that incorporates popular mobilization against pre-existing institutions as a key trait; and third, as a particular practice of (...) constitutional enforcement that involves weak and selective implementation, often through institutional capture. By considering not only the texts of constitutions but also the ways in which they are changed and implemented, we hope to complement legal perspectives of mixed constitutions with a sociopolitical analysis of practices and contexts. By capturing the distinctive contribution of Latin American populism to the discussion of mixed constitutions, we seek to challenge both legal conceptions of constitutionalism that reduce it to negative or constraining features, and political conceptions of populism that simply equate it to authoritarian rule.

We determine the number of non‐isomorphic semi‐Heyting algebras on an n‐element chain, where n is a positive integer, using a recursive method. We then prove that the numbers obtained agree with those determined in [1]. We apply the formula to calculate the number of non‐isomorphic semi‐Heyting chains of a given size in some important subvarieties of the variety of semi‐Heyting algebras that were introduced in [5]. We further exploit this recursive method to calculate the numbers of non‐isomorphic semi‐Heyting chains with (...) n elements such that removing the mth element () we are left with a subalgebra. We also solve a related problem posed in [1] of determining the number of ways a semi‐Heyting chain with elements can be extended to a n element semi‐Heyting chain by adding a new element in the mth place. Finally we combine these results by finding a second way to calculate the numbers that provides some extra information. (shrink)

The creation of a specialized executive position that oversees sustainability activities represents a distinct shift in the structure of top management teams and their approach for addressing sustainability concerns. However, little is known about these management team members, namely the corporate sustainability officers or CSOs. We examine CSO appointments and their association with subsequent sustainability performance. Our results indicate that the creation of a CSO position may represent more of a symbolic versus substantive governance mechanism. Further tests suggest that CSO (...) expertise and the firm’s existing sustainability performance affect the association between the CSO and post-appointment sustainability performance. We find no association between CSO appointments and subsequent sustainability performance for firms that were already poor performers, while firms possessing relatively higher levels of prior sustainability performance appointing a CSO begin to experience significant improvements to performance after 3 years. We further find that CSOs with prior sustainability expertise are associated with increases in sustainability performance in firms that were already strong performers, but not in firms with poor sustainability performance. Non-expert CSOs, on the other hand, are associated with initial decreases in performance for poor performing firms, whereas better performing firms hiring non-expert CSOs are able to rely on other sustainability attributes of the firm and benefit from improvements in performance in the long term. We discuss the potential importance of these positions as it relates to symbolic versus substantive governance mechanisms through the lens of top management team literature streams. (shrink)

AimsA negative association between the lower level of psychological resilience and increased risk of compassion fatigue and higher Coronavirus disease 2019 stress has been revealed. However, bibliometric studies have not been performed to comprehensively investigate this topic. This study aimed to identify the status and trends in the CF and PR field from 2008 to 2021 and during the COVID-19 pandemic.MethodsWe identified relevant literature from the Web of Science Core Collection® database using “resilience” and “compassion fatigue” on September 30, 2021. (...) All search results were exported in plain text format for collaboration network analysis, reference-based co-citation analysis, analysis of journals, and keywords-based co-occurrence analysis, which were performed using Citespace® 5.8.R1.ResultsA total of 388 publications were identified finally, and there has been an increasing trend in the annual number of publications with light fluctuations. The analysis of journals and keywords indicated that nurses and social workers are the main research targets, and their mental problems are the main research topics. The turnover intention of health care providers has been a research focus, particularly during the COVID-19.ConclusionThe results of the present study help us understand the status of the CF and PR field and its recent developments.

The state of computing science and, particularly, software engineering and knowledge engineering is generally considered immature. The best starting point for achieving a mature engineering discipline is a solid scientific theory, and the primary reason behind the immaturity in these fields is precisely that computing science still has no such agreed upon underlying theory. As theories in other fields of science do, this paper formally establishes the fundamental elements and postulates making up a first attempt at a theory in this (...) field, considering the features and peculiarities of computing science. The fundamental elements of this approach are informons and holons, and it is a general and comprehensive theory of software engineering and knowledge engineering that related disciplines (e.g., information systems) can particularise and/or extend to take benefit from it (Lakatos’ concepts of core theory and protective belt theories).
