The business world is facing a very complicated situation due to the COVID-19 pandemic. Small- and medium-sized companies —both in Spain and at the global level—are seeing their survival jeopardized by a fall in revenues. This scenario is aggravated in the case of micro-SMEs headed by female entrepreneurs. Accordingly, micro-SMEs, particularly those led by female entrepreneurs, need to reinvent themselves to overcome the current adversities that could lead to the destruction of their businesses and hence their jobs. One of the (...) ways to do this is to take advantage of digital transformation. Therefore, the aim of this paper is to analyze which variables influence the financial results of female-led Spanish micro-SMEs when they carry out social marketing actions. For that purpose, an online survey was designed and analyzed using the “PROCESS” macro. Results show that social media marketing actions have significant effects on financial performance. (shrink)

Digital transformation has allowed to offer additional services - which complement the main product - both in terms of use, emotional and relationship terms. Focused on a traditionally rational insurance customer offering a value that explores the customer's emotions, from co-creating with the user, allows brand differentiation. Given this idea, this document has three purposes. First, identify the role of expectations and the perceived quality of the customer's digital experience. Secondly, to identify the relationship between experience and satisfaction gained in (...) private insurance web areas. Third, identify the most valued digital attributes by the user. A sample of 4,178 customers registered was analyzed using the partial least squares technique. The model is highly predictive to customer experience and evidence the important relationship between the WOW effect and satisfaction, as well as the weak but doble role that expectations play on insurance digital self-service. The model demonstrates that expectations are only relevant before web consumption, because during the process it is the perceived digital quality, in particular the usefulness, information and technology, that offer a true customer experience. This article offers high academic value because it more accurately defines the determinants of the digital insurance customer experience and its effect on customer satisfaction in digital services. While expectations influence attitude before service, this research reveals that perceived digital quality is what delivers a true customer experience. Strategically, the implications are immediate in the field of business as it shows the importance of co-creation in digital design, not only because of the significant savings in implementation costs but also because it guarantees a greater experience, essential in the loyalty of its customers. This ensures the sustainable growth of the company. (shrink)

RESUMEN Este artículo explora si hay algún fundamento sólido para atribuir a Leonardo da Vinci prioridad en la formulación del símil que lleva a concebir el ojo como una cámara obscura. Aquí, se defiende una posición pesimista. No obstante, el artículo resalta algunos aportes del pintor renacentista que pueden considerarse contribuciones a la consolidación del símil. ABSTRACT The article explores whether there is any solid basis for attributing to Leonardo da Vinci the priority in formulating the simile that leads to (...) conceiving the eye as a camera obscura. Here, a pessimistic position is defended, however, the article highlights some of Leonardo's contributions to the consolidation of the simile. (shrink)

This article investigates whether acts of plagiarism are predictable. Through a deductive, quantitative method, this study examines 517 students and their motivation and intention to plagiarize. More specifically, this study uses an ethical theoretical framework called the Theory of Reasoned Action and Planned Behavior to proffer five hypotheses about cognitive, relational, and social processing relevant to ethical decision making. Data results indicate that although most respondents reported that plagiarism was wrong, students with strong intentions to plagiarize had a more positive (...) attitude toward plagiarizing, believed that it was important that family and friends think plagiarizing is acceptable, and perceived that plagiarizing would be an easy task. However, participants in the current study with less intention to plagiarize hold negative views about plagiarism, do not believe that plagiarism is acceptable to family, friends or peers, and perceive that the act of plagiarizing would prove difficult. Based on these findings, this study considers implications important for faculty, librarians, and student support staff in preventing plagiarism through collaborations and outreach programming.

La solución de los problemas biojurídicos depende fundamentalmente de la concepción del derecho y de la valoración de la vida humana de la que se disponga. La supresión de la perspectiva de la justicia, unida a la consideración de la vida humana como mera propiedad inmanente de un ser vivo que, en el caso del hombre, permitirá la libre disposición de ella, conducirá necesariamente a una degradación de la protección jurídica de la vida. Por el contrario, la vinculación del derecho (...) con la moral, a través de la justicia, propia de la concepción óntico-valorativa o, al menos, de una concepción del derecho que aúne las tres dimensiones, conducirá a una más firme defensa jurídica de la vida. Desde esta perspectiva se analiza la desprotección jurídica, y por tanto moral, de la vida en la regulación del aborto en la legislación española. (shrink)

In this paper, we evaluate Button’s claim that knot is a nasty connective. Knot’s nastiness is due to the fact that, when one extends the set \ with knot, the connective provides counterexamples to a number of classically valid operational rules in a sequent calculus proof system. We show that just as going non-transitive diminishes tonk’s nastiness, knot’s nastiness can also be reduced by dropping Reflexivity, a different structural rule. Since doing so restores all other rules in the system as (...) validity-preserving, we are inclined to conclude that there, knot is not that nasty. However, since motivating non-reflexivity is harder than motivating non-transitivity, we also acknowledge that disagreement with our conclusion is possible. (shrink)

O ponto de partida do presente ensaio é o entendimento de que a arte constitui um dos motivos catalisadores, se não mesmo um dos temas maiores da reflexão de Maurice Merleau-Ponty. Na interpretação do autor, o filósofo da percepção, aquele que, de todos os pensadores contemporâneos, conferiu ao corpo po um estatuto que a reflexão do século XX ainda não lhe concedera, chegou à arte por necessidade intrínseca do seu próprio caminho especulativo, vindo a reflexão sobre a expressão artística a (...) dar um contributo essencial para a constituição do seu próprio pensamento, contributo esse que se vai adensando, desde a Fenomenologia da Percepção até O Visível e o Invisível e O Olho e o Espírito, a ponto de poder dizer-se que na arte, particularmente na arte moderna, encontrou Merleau-Ponty uma filosofia à l'oeuvre, apesar da ausência do conceito, a que é, de facto, alheia a expressão artística.

It has been claimed that contracting connectivesContracting connective are conditionalsConditional. Our modest aim here is to show that the conditional-like features of a contracting connectiveContracting connective depend on the defining features of the conditionalConditional in a particular logic, yes, but they also depend on the underlying notion of logical consequence and the structure of the collection of truth values. More concretely, we will show that under P-consequenceP-consequence and suitable satisfiability conditions for the conditionalConditional, conjunctionsConjunction are contracting connectivesContracting connective for some (...) logics without thereby being conditional-ish.

Embora a expressão ‘neologismo’ nos dê a impressão de uma palavra exótica, que causa uma certa estranheza ao usuário da língua, ela, na verdade, refere-se a qualquer palavra recém-criada que entra em uso num idioma. Toda língua, em seu estágio inicial, é simples, rudimentar e refere-se, principalmente, ao concreto. Conforme a sociedade vai-se aprimorando e tornando-se complexa, também a língua usada por essa sociedade vai-se aprimorando, refinando, atendendo às necessidades de seus falantes. Com o latim não foi diferente. Para se (...) transformar numa língua capaz de expressar a grandeza da civilização romana, o latim teve que, dentre outros processos, ampliar seu léxico, criando novas palavras. E é esse processo de produtividade lexical que este trabalho se propõe a observar, ainda que superficialmente. (shrink)

El estoicismo es una de las filosofías de vida que más ha influenciado a la sociedad occidental desde su origen en la antigua Grecia. Esto se debe a su conocimiento de la naturaleza humana y su adaptación a ella, a su profundidad filosófica de base lógica y a su condición empírica y práctica. De hecho, podemos definir el estoicismo como la forma más potente y eficaz que se conoce de lo que hoy llamamos autoayuda, pues son innegables los beneficios que (...) aporta una vez que se adoptan sus principios. De la mano del autor, médico y humanista, este libro muestra de modo magistral los profundos valores de esta filosofía de vida y, especialmente, la forma de aplicarlos en la vida cotidiana. (shrink)

Alberic of Paris put forward an argument, ‘the most embarrassing of all twelfth-century arguments’ according to Christopher Martin, which shows that the connexive principles contradict some other logical principles that have become deeply entrenched in our most widely accepted logical theories. Building upon some of Everett Nelson’s ideas, we will show that the steps in Alberic of Paris’ argument that should be rejected are precisely the ones that presuppose the validity of schemas that are nowadays taken as some of the (...) most trivial logical truths: (A∧B) → A and (A∧B) → B, i.e. Simplification.

ABSTRACT In this brief note we explore a couple of features of the semantics for indicative conditionals provided by Field. Those features strikingly resemble some controversial principles in connexive logic. We will show that although Field’s semantics has the technical means to stand to the mentioned features, more work is needed to make some of its outcomes less unintuitive.

Authentic leadership has become increasingly important in the literature, attracting the attention of many scholars in the last decade. This study adopted an employee-centered perspective to guide its examination of the relationship between authentic leadership and individual performance and investigation of the sequential mediation of employees’ affective commitment and individual creativity. An analysis was conducted of data collected from 214 employees working in different business sectors. The results reveal a statistically significant positive relationship between authentic leadership and employees’ workplace performance, (...) which are both directly connected and indirectly linked through the two proposed psychosocial mechanisms. The findings thus indicate that authentic leadership reinforces workers’ emotional connection with their organizations, thereby increasing their individual creativity and, subsequently, promoting better on-the-job performance. This study presents new and significant results since, on the one hand, it relied on a sequential mediation analysis of variables and, on the other hand, integrated the four main constructs into a single model. The proposed model displays the chain of effects between authentic leadership, affective commitment, individual creativity, and employee workplace performance. Implications for organizational management are discussed. (shrink)

It is well established that demographic representation in clinical research is important for understanding the safety and effectiveness of novel therapeutics and vaccines in diverse patient populations. In recent years, the National Institutes of Health and Food and Drug Administration have issued guidelines and recommendations for the inclusion of women, older adults, and racial and ethnic minorities in research. However, these guidelines fail to provide an adequate explanation of why racial and ethnic representation in clinical research is important. This article (...) aims to both provide the missing arguments for why adequate representation of racial and ethnic minorities in clinical research is essential and to articulate a number of recommendations for improving diversity going forward.Appropriate racial and ethnic representation and fair inclusion help (1) increase the generalisability of clinical trial results, (2) equitably distribute any benefits of clinical research and (3) enable trust in the research enterprise.

La arquitectura digital ha alterado de manera decisiva la sociedad y, en consecuencia, demanda respuestas legales. De la Internet desarrollada en la década de 1970 con fines militares, casi nada permanece igual. La plataforma ha otorgado un poder sin igual a las empresas de tecnología, cambiando la forma en que nos comunicamos, abordamos la política, negociamos y también cómo nos relacionamos. En la economía digital actual, la atención de los usuarios es el principal producto, y estos usuarios también son productores (...) de contenido. En este modelo, se facilita la propagación de información falsa, lo que pone en riesgo la democracia y la ciencia. Para abordar estos fenómenos, es fundamental desarrollar y aplicar mecanismos adecuados de regulación de las plataformas para proteger a la sociedad y la libertad. Este estudio se basa en este contexto para analizar algunas respuestas regulatorias que se están debatiendo en Brasil. (shrink)

Online education has become an essential component of education. Thus, several factors, such as the student’s learning strategy and motivation, generally contribute to their academic success. This study investigates the relationship between learning strategies, motivation, and online learning environment among 150 first-year college students. Employing correlational design, the statistical findings of the study reveal that the r coefficient of 0.59 indicates a moderate positive correlation between the variables. The p-value of 0.00, which is less than 0.05, leads to the decision (...) to reject the null hypothesis. Hence, a significant relationship exists between learning strategies, motivation, and the online learning environment. (shrink)

In this essay I present some of my thoughts on the issue of boundaries in the professional relationship between service users and social workers. As a graduate student of social work, I had an opportunity to discuss ethical dilemmas in an international perspective in one of my courses. A guest professor, who provided international perspectives, was Prof. Kim Strom from UNC at Chapel Hill in North Carolina, USA. The lectures offered a fresh perspective that raised many questions about thick and (...) thin boundaries in social work – especially when approaching social work by following prevailing guidelines for social work in Slovenia requiring us to co-create solutions through dialogue with service users, keeping in mind that service users are actually the ones who are the experts from experience. In this way, the working relationship seeks to foster a sense of partnership between social workers and service users. In this essay I would like to challenge the idea of rigid boundaries in social work and explore the possibility of fluid boundaries, keeping in mind that boundaries should reflect their main purpose, which I believe is to protect human dignity.

The purpose of this article is to investigate human spatiality and perception in general, with the experience of adventure sports as its background. These activities highlight especially our strong relationship with the world when we consider the specific way in which the environment participates in the development of human potential. We first analyse the notions of risk and instability as important elements in adventure sports. Then we explore the notion of experience and spatiality, considering the way in which we establish (...) our relationship with the world. The theoretical background is found in the phenomenology of Merleau-Ponty and Bachelard’s phenomenology of imagination to investigate perspectives of space among adventurers. We hold that more than a different range of corporeal techniques, adventure sports can teach us a way of interrogating and looking at the world. They require a peculiar sensibility that allows our body to experience the environment in favour of a corporeal wisdom. Alternative sports indicate the possibility that we have to build up different ways of inhabiting the world and comprehending it. (shrink)

No século XIX, Marie Pape-Carpantier teve uma significativa importância para a educação da criança de 2 a 6 anos. Sua influência situa-se na adoção do método intuitivo para a educação dos sentidos - lições de coisas -, na proposta pedagógica destinada à Educação Infantil - salas de asilo; na criação de materiais didáticos para auxiliar no desenvolvimento do método natural; na orientação de modelos de mobílias para as escolas. Produz uma imensa obra para professores e alunos, traduzida em vários países: (...) Grécia, Inglaterra, Itália, Suécia, Espanha, Brasil, e publicada até a segunda década do século XX, perfazendo inúmeras edições. O estudo analisa a trajetória e a contribuição da educadora, destacando as principais ideias, pelo espírito prático-experimental, que prenuncia a escola ativa. (shrink)

This work investigates knowledge systems intrinsic to African civilizations to ascertain ways in which those systems can help validate or invalidate the argument pertaining to the existence of an African epistemology. This approach calls for a paradigm shift in conceptualizing and researching African epistemology free from Eurocentric and Afrocentric biases.

Le concept d'identité est à l'ordre du jour dans le débat contemporain. Son usage populaire et vernaculaire, faisant obstacle à sa compréhension conceptuelle, nous oblige davantage à y réfléchir afin de mieux la définir et la distinguer. Sans doute, il s'agit non seulement d'un concept flou et fourre-tout, mais aussi les enjeux épistémologiques qu'il comporte sont d'ordre psychologique, sociologique, culturel, religieux, politique, juridique, philosophique, etc. Loin d'être un concept insulaire, l'identité doit être pensée sous l'angle relationnel, car son analyse est (...) indissociable des autres concepts tels que l'existence, l'altérité, la différence, le temps, entre autres. En se dissociant de ces catégories, l'identité ne peut avoir un sens proprement philosophique. Mais ce ne sont pas les seules questions philosophiques que soulève l'identité. Il y a sans doute aussi celles relatives à la culture, à la spiritualité, à la génétique, à la société, à la politique, au droit, qui ont toutes une portée philosophique. Ainsi les identités culturelle, spirituelle, génétique, normative, sociale, politique, nationale, doivent faire l'objet d'une réflexion philosophique, car elles soulèvent plusieurs controverses qui suscitent l'étonnement, le doute et l'inquiétude. Bref, toutes les questions que soulève l'identité se résument à une question principale : qu'est-ce que l'identité humaine? Les réponses à cette question sont, depuis les origines de la pensée jusqu'à aujourd'hui, des essais de définition en raison de la complexité de la nature humaine que les sociétés, l'histoire, les hommes n'ont pas fini de révéler."--Page 4 of cover.

Reason in History provides theoretical clarity and conceptual analysis that is well a propos, considering the potential and actual societal changes we are witnessing. Has there ever been or can there be a structural change that would thereby reveal an internal dynamic in African societies? For us, the elements determining the forms and law of social changes are less interesting than the possibility of change itself. Is change universal of just a property of a certain type of social totality? Hegel's (...) theories seem to do Africa justice or simply match the true reality of traditional African societies. Africa is not and has never been static. The book also fosters a greater appreciation of the grandeur and complexity of Hegel's dialectic: he is still judging our world despite what postmodernist scholars and ethnophilosophers think.

This study addresses race and ethnic relations from the standpoint of Schutzian phenomenological social psychology. It shows how this approach, by focusing on intersubjectivity and the construction of self and identity, both yields an intimate look at race and reveals the critical thrust, hence, political relevance, of phenomenology.

Lack of vaccine confidence can contribute to drops in vaccination coverage and subsequent outbreaks of diseases like measles and polio. Low trust in vaccines is attributed to a combination of factors, including lack of understanding, vaccine scares, flawed policies, social media and mistrust of vaccine manufacturers, scientists and decision-makers. The COVID-19 crisis has laid bare societies’ vulnerability to new pathogens and the critical role of vaccines in containing this and future pandemics. It has also put science at the forefront of (...) the response, with several governments relying on academics to help shape policy and communicate with the public. Against this backdrop, protecting public trust in scientists and scientific output is arguably more important than ever. Yet, conflicts of interest in biomedical research remain ubiquitous and harmful, and measures to curb them have had limited success. There is also evidence of bias in industry-sponsored vaccine studies and academics are voicing concerns about the risks of working in a CoI prevalent research area. Here, we set out to challenge established thinking with regard to vaccine confidence, by shifting the gaze from a deficit in public understanding towards probity in research relationships and suggesting an alternative and perhaps complementary strategy for addressing vaccine mistrust. We argue that a concerted effort needs to be made to revisit the norms that undergird contemporary vaccine research, coupled with a willingness of all stakeholders to reimagine those relationships with an emphasis on demonstrating trustworthiness and probity.
