The disease brought about by the SARS-CoV-2, COVID-19 coronavirus has had an unprecedented global impact. Confinement to control the outbreak may have mental health consequences for the most vulnerable in the population, including adolescents. This study aims to describe and analyze the relationships between the stress variables, Emotional Intelligence and the intention to use cannabis in healthy adolescents, before and after the end of the COVID-19 pandemic containment stage. A comparative correlational study was carried out with validated self-completed questionnaires through an online platform. The sample is made up of adolescents aged 13–17 from two different schools in Ponferrada. The analysis of correlation and differences between the groups indicate that confinement has had effects on the mental health of the adolescents, specifically on the emotional manifestations of stress. Furthermore, significant gender differences were found for stress values and Emotional Intelligence. However, no differences have been found for cannabis use intention.

This article explores the proposal offered by Ian Hacking for the distinction between natural and social sciences—a proposal that he has defined from the outset as complex and different from the traditional ones. Our objective is not only to present the path followed by Hacking’s distinction, but also to determine if it constitutes a novelty or not. For this purpose, we deemed it necessary to briefly introduce the core notions Hacking uses to establish his strategic approach to social sciences, under the assumption that they are less well known that the ones corresponding to his treatment of natural sciences

This study examines whether character strengths predict resilience (operationalized as stable or higher mental health and subjective well-being despite an adverse event) over a period of approximately one month during the COVID-19 pandemic lockdown in Spain. Using a longitudinal design, participants (N = 348 adults) completed online measures of sociodemographic data, information regarding their situation in relation to the COVID-19, character strengths, general mental health, life satisfaction, positive affect and negative affect. All variables were measured at Time 1 and Time 2, except for sociodemographic and most COVID-related information (Time 1 only). Time 1 data collection was conducted between March 21, 2020 and April 2, 2020, i.e., approximately the second week of lockdown in Spain. Time 2 data collection was conducted between April 24, 2020 and May 18, 2020, after the Spanish government announced ita intention to progressively release the lockdown. A principal component analysis of character strengths was conducted. Five character strength factors were extracted: fortitude, goodness, intellectual, interpersonal, and restraint. Factor structures at Times 1 and 2 were highly consistent. All character strength factors at Time 1 correlated positively with life satisfaction and positive affect, and negatively with negative affect and mental health at T2 (higher scores in the mental health measure indicate poorer mental health). Fortitude strengths showed the highest correlations. We conducted a series of regression analyses with strength factors at Time 1 as predictors, and mental health, life satisfaction, and positive and negative affect as dependent variables, controlling for their baseline levels. To test the directionality of the relationship between strengths and the dependent variables, all analyses were reversed. All character strength factors predicted an increase in mental health. They also predicted positive affect, with the exception of strengths of restraint. Fortitude, intellectual and interpersonal strengths predicted an increase in life satisfaction. Finally, fortitude strengths, interpersonal strengths, and strengths of restraint, predicted a decrease in negative affect. None of the reversed analyses yielded significant effects. Limitations, implications, and possible character strengths-based interventions aimed at promoting mental health in the COVID-19 pandemic are discussed.

The aim of this study is to examine whether gender diversity on audit committees influences financial reporting quality by using panel data of Spanish listed firms. The financial reporting quality of firms is measured by the type of opinion received in the audit report. We estimate various panel data models of audit opinions and control for factors that are traditionally found to impact audit opinions. This study provides evidence to support the hypotheses that the percentage of females on ACs reduces the probability of qualifications due to errors, non-compliance or the omission of information. Furthermore, the results also find that the percentage of female directors on ACs, the percentage of independent female directors on ACs and ACs chaired by females increase the likelihood of further transparency by disclosing audit reports with uncertainties and scope limitation qualifications.

Hacia 1693 -cuando William Penn se proponía comenzar su Ensayo para la paz presente y futura de Europa, relegando a la condición de estatua de bronce o de piedra al hombre incapaz de estremecerse ante las interminables guerras que asolaban Europa-, estaba a punto de finalizar un siglo bélico donde los haya, pues todos los desencuentros entre dinastías, parlamentos y credos se habían dirimido por las armas. Lamentablemente este proceder era contemplado como el más natural de los recursos para solucionar las disensiones.

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).

The aim of this research is to examine what impact female institutional directors on boards have on corporate performance. Previous research shows that institutional female directors cannot be considered as a homogeneous group since they represent investors who may or may not maintain business relations with the companies on whose corporate boards they sit. Thus, it is not only the effect of female institutional directors as a whole on firm value that has been analysed, but also the impact of pressure-resistant female directors, who represent institutional investors that only invest in the company, and do not maintain a business relation with the firm. We hypothesize that there is a non-linear association, specifically quadratic, between institutional and pressure-resistant female directors on boards and corporate performance. Our results report that female institutional directors on boards enhance corporate performance, but when they reach a certain threshold on boards, firm value decreases. In line with female institutional directors, pressure-resistant female directors on boards also increase firm value, but only up to a certain figure, above which they have a negative impact on firm performance. These findings are consistent with an inverted U-shaped relationship between female institutional directors and pressure-resistant female directors and firm performance.

Spain has become a country receiving immigrants in the last years. The majority of the items of news related to immigration that appear in the press exhibit negative characteristics. The main purpose of this article is to observe the linguistic and visual representation of Sub-Saharan immigrants in a sample of the Spanish press in order to answer the following research questions: how are Sub-Saharan immigrants portrayed linguistically and visually in the given press? What are the implications of the choices in language and images? The researcher collected all the pieces of news related to Sub-Saharan immigrants in the three most popular Spanish newspapers, i.e. El País, ABC and El Mundo from 1 June 2011 to 31 March 2013. Visual grammar and critical discourse analysis will be used in order to deconstruct the visual and linguistic representation of such immigrants. In addition, van Leeuwen's [2008 Discourse and practice. New tools for critical discourse analysis. Oxford: Oxford University Press.] classification of social actors will be used in the analysis. The analysis demonstrates that the representation of Sub-Saharan immigrants displays the following characteristics: they are represented as vulnerable, lacking autonomy, as victims, etc. This representation does not contribute to the fact that the autochthonous population favours the integration of immigrants into the socio-economic structure, exercising the same rights as the Spanish population.

Ian Hacking has defined himself as a philosopher in the analytic tradition. However, he has also recognized the profound influence that Michel Foucault had on much of his work. In this article I analyse the specific imprint of certain works by Foucault—in particular Les mots et les choses—in two of Hacking’s early works: Why Does Language Matter to Philosophy? and The Emergence of Probability. I propose that these texts not only share a debt of Foucauldian thought, but also are part of what I believe is Hacking’s central project: the analysis of the historical and situated conditions of possibility for the emergence of concepts and of objects, inspired also by the French philosopher’s thought.

This paper presents the manner in which the DNA, the molecule of life, was discovered. Unlike what many people, even biologists, believe, it was Johannes Friedrich Miescher who originally discovered and isolated nuclein, currently known as DNA, in 1869, 75 years before Watson and Crick unveiled its structure. Also, in this paper we show, and above all demonstrate, the serendipity of this major discovery. Like many of his contemporaries, Miescher set out to discover how cells worked by means of studying and analysing their proteins. During this arduous task, he detected an unexpected substance of unpredicted properties. This new substance precipitated when he added acid to the solution and it dissolved again when adding alkali. Unexpectedly and by a mere fluke, Miescher was the first person to obtain a DNA precipitate. The paper then presents the term serendipity and discusses how it has influenced the discovery of other important scientific milestones. Finally, we address the question of whether serendipitous discoveries can be nurtured and what role the computer could play in this process.

Through the ethnographic record of the subsistence activities partially or completely performed in the domestic sphere in two Mbyá-Guaraní settlements in Misiones (Argentina), we outline factors important in describing the local natural environment. Data was collected through systematic observation and also through semi-structured interviews. Analysis indicates that the natural environment of the area is characterized by the indigenous community in several different ways. Thus, local people view the environment as made up of different “micro-environments,” and they consequently think of the elements that compose these “micro-environments” as having different, distinct characteristics. In the context of their daily activities, both these “micro-environments” and the elements that compose them are regarded as resources, in that they are viewed in terms of what is in them relevant to the subsistence of these groups in the rainforest. It is the intention of this study to initiate the systematic recording and processing of information on how these indigenous communities know and manage the natural resources available to them in their daily life.
