Agents know some but not all logical consequences of what they know. Agents seem to be neither logically omniscient nor logically incompetent. Yet finding an intermediate standard of minimal rationality has proven difficult. In this paper, I take suggestions found in the literature (Lewis, 1988; Hawke, Özgün and Berto, 2020; Plebani and Spolaore, 2021) and join the forces of subject matter and impossible worlds approaches to devise a new solution to this quandary. I do so by combining a space of (...) FDE worlds (Berto and Jago, 2019) with a Lewisian (1988) understanding of subject matters as partitions. By doing so, I show how subject matters impose some order in the anarchic space of FDE worlds, while the worlds allow for distinctions between contents which would not otherwise be available. Combining the two approaches, then, brings us closer to the desired closure principles for knowledge of minimally rational agents. (shrink)

There has been much debate recently on the question whether essence can explain modality. Here, I examine two routes to an essentialist account of modality. The first is Hale's argument for the necessity of essence, which I will argue is — notwithstanding recent attempted defences of it — invalid by its very structure. The second is the proposal that it is essential to essential truth that it is necessary. After offering three possible versions of the view, I will argue that (...) each fails to provide a metaphysical explanation of necessity in terms of essence. (shrink)

This brief review of Mario Bunge’s research on physics begins with an analysis of his masterpiece Foundations of Physics, and then it discusses his other contributions to the philosophy of physics. Following that is a summary of his more recent reactions to scientific discoveries in physics and a discussion of his position about non-locality in quantum mechanics, as well as his changing opinions on the nature of spacetime. The paper ends with a brief assessment of Bunge’s legacy concerning the foundations (...) of physics. (shrink)

Transformar el modo de vida individual es necesario para abordar la crisis ecosocial, y resulta perentorio que las políticas comprometidas con su resolución promocionen una capacidad individual de acción ecosocial. Sin embargo, parece que cierta brecha motivacional está obstaculizando la transformación del modo de vida individual. A fin de dar respuesta a esta brecha, ensayamos una mixtura del enfoque de las capacidades con las teorías de Hartmut Rosa. Argumentamos que la resonancia natural funge de factor personal de conversión necesario, si (...) bien no suficiente, para la capacidad de acción ecosocial; y que una política que promocione la resonancia natural se adecuaría también a los requisitos impuestos al desarrollo humano tanto por el enfoque de las capacidades como por la sostenibilidad.

Democratization process has become the global demand of the present century. The Millennium Development Goal (MDG) gave credence to this development. Nigeria and South Africa have had checkered history of dictatorship under military rule and obnoxious apartheid policy respectively. Both countries embraced the current wave in the 1990s. The exploration of this development is our central focus. To do this, the paper examined the following: the relationship between type of electoral system and the conduct of elections in Nigeria and South (...) Africa; and the efficacy of majoritarian and proportional representation systems as applied in both countries. Our findings indicated that majoritarian system accounted for electoral irregularities while proportional representation contributed to wide acceptance of polls. The data were generated from the secondary source. We recommended the adoption of the proportional electoral system as practiced in South Africa and absolute constitutionalism for both countries so as to engender the principles of rule of law.

It is common in psychiatry and other sciences to describe an individual or a type of individual in terms of its disposition to manifest specific effects in a particular range of circumstances. According to one understanding, dispositions are statistical regularities of an individual or type of individual in specific circumstances. According to another understanding, dispositions are properties of individuals in virtue of which such regularities hold. This entry considers a number of ways of making each of these senses of disposition (...) more precise while discussing a number of dangers lurking in careless use of the concept of a disposition.

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...) of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

The importance of education in boosting the manpower of an economy cannot be overemphasized. This critical sector has been bastardized, relegated and put in a dust bin position through paltry figures usually allocated to it by the Federal Government of Nigeria. This paper presents a holistic trend of budgetary activities in Nigeria with a particular focus on the allocation to the Education sector using times series approach from 2009-2018. Two research questions were answered using secondary data gathered from the Central (...) Bank of Nigeria's Statistical Bulletin, 2018. Collected data were analyzed using descriptive statistics, while the results of the analysis showed that, the total allocation to the education sector from 2009 – 2018 is N4,038,115,000,000. The results further revealed a difference of N 10,311,805,000,000 between UNESCO benchmark of 26% and the actual allocation to the education sector for the same time period. It was concluded that the total allocation made to the education sector within the time period of 2009-2018 is generally low, and below the UNESCO benchmark. Based on the findings, it was recommended amongst others that the Federal Government of Nigeria should adequately fund the educational sector by allocating at least 26% of her budget to the education sector as prescribed by UNESCO.

This research examined the management of financial and non-financial resources by Calabar Metropolis’ public secondary school principals in relation to the fulfillment of institutional goals. Null hypotheses were developed based on the two specific objectives guiding the study. The study used the ex-post facto research design under the quantitative research framework. A census approach was adopted in enumerating all the 69 school managers (24 principals and 45 vice principals) in Calabar Metropolis, Nigeria. A validated questionnaire, with a reliability index of (...) .90, was used for data collection. It was shown that there is a considerable association between the management of financial resources by school leaders and the fulfillment of institutional goals. A significant relationship was also established between principals’ management of non-financial resources (such as school libraries, school records and human resources) and the fulfillment of institutional goals in secondary schools. It is argued that to fulfil educational goals, financial and non-financial resources’ management in public secondary schools are critical. Policy and theoretical implications for successful educational management were discussed in light of this result. (shrink)

Chapter fifteen of the book Why Nations Fail by Acemoglu and Robinson titled Prosperity and Poverty is the last and summarizing chapter of the masterpiece. The work undertook an intellectual and rigorous journey to logically and coherently expose the causes of obvious inequality amongst nations of the world. The chapter has its central message that the extractive economic and political institutions are hypothetically the reason why some countries are poor; the study highlighted the features of extractive institutions to include: quick (...) economic growth, inherent fighting, systematic disorder, and elite domination. The work is an attempt to comprehensively review and bring to bear an in-depth understanding of prosperity and poverty amongst nations of the world. It, therefore, states that to move into prosperity, poor nations have to create and develop a more inclusive economic and political institution. Thus; the review concluded that poor countries of the world need strong inclusive institutions to leapfrog into prosperity. (shrink)

The existing body of knowledge has witnessed gaps arising from the paucity of research literature on the quality of educational research output in higher education. This study shows how the management of data in higher education affects the quality of academic research conducted by university lecturers in South-South Nigeria. The study adopted a factorial research design. The population of this study includes all the Faculty of Education academic staff in both public and private universities situated in South-South Nigeria. Using results (...) of a survey administered to a sample of 602 accessible lecturers during data collection, one research question and one null hypothesis were resolved in the study. Multiple regression was employed in the analysis of data. Findings revealed amongst others that; data storage, data security, data retrieval, data sharing, and data re-use jointly contributed to the total variance in educational research effectiveness in terms of proper citations by 56.25%, problem-solving by 22.14%, knowledge creation by 34.50%, and generation of testable data by 36.88%; and their composite influence on educational research effectiveness in terms of proper citations, problem- solving, knowledge creation, and generation of testable data, is statistically significant. Based on the findings of this study, it was concluded that data management practices play an important role in higher education that significantly influences the quality of research output in universities in South- South Nigeria. It was recommended among others that, there should be an up-to-date database or data warehouse in Ministries of Education where researchers can easily access data in order to increase the quality of researches by eliminating the problems of data fabrication and falsification.

Every time we perceive the scent of an end, we are summoned to position ourselves, to express what has been, what is our condition and what is to come. Ours is, certainly the time of the end of times. A time in which the end has become the void center around which we revolve. Philosophy only speaks when there is a limit at stake: a beginning, an end, a border, a frontier. And yet, there is no measure anymore to determine (...) what is actuality or the present, what is contemporary. Time is fragmented as well as space. There is a multiplicity of time scales (cosmic, planetary, human, cultural, personal) and velocities (the human body, our cars and trains, information), but also of subjective appropriations (what is urgent, what should come first, how much time do we have left). There is no “fundamental” difference between life-time and clock-time. There are several clocks and several lives. There is also a multiplicity of space scales (elemental particles, molecules, living organisms, living collectives, all living-species), different modes (continuous, discontinuous, with borders, infinite, homogeneous, non-trivially connected), different subjective relationships to it (earth as our space -be it in terms of Husserl or of Galilei-, the cultural world-worlds, my city, my house, my body). Far is the possibility of fixing a last instance or a fundamental scale, the possibility of a whole in which we could univocally place the particulars, or the chance of finding the last constituents of being (the atoms: physical, logical, metaphysical, social, etc.).

A nadie sorprende decir que lenguaje y dinero son sistemas simbólicos o sistemas de intercambio de información. Tampoco sorprende a nadie resaltar el hecho de que las computadores funcionan esencialmente con la versión más formalizada del lenguaje.

El lenguaje posee un elemento estructural, formal, “maquínico” que le permite copiarse en toda una población. Éramos ya máquina antes de (...) inventar una. Pero este acontecimiento de producir una máquina fuera de nosotros, de darle energía a un “inconsciente” es un acto inédito. Si entendiéramos cómo es que el capitalismo contemporáneo se realiza a través de la virtualidad informática comenzaríamos a contemplar la posibilidad de que ahora sean los algoritmos y no la ambición subjetiva lo que producirá las nuevas burbujas inmobiliarias. O al menos entenderíamos que mientras más extendemos el mundo hacia regiones virtuales, el capital lo sigue para crear ahí nuevos nichos de mercado. Y viceversa, la expansión virtual del dinero exige la creación de nuevos programas, algoritmos, portales de inversión y de consumo. (shrink)

En cuanto a las técnicas para la recolección y análisis de la información, se utilizaron cuantitativas y cualitativas, como la observación participante, el diario de clase y la triangulación, entre otros. La investigación se efectuó en dos ciclos con estudiantes del Programa Educación, Proyecto Educación Integral, de la Universidad Nacional Experimental “Rafael María Baralt”. Los resultados evidencian mejoras sustantivas en los niveles de comprensión de la lectura del grupo, sobre todo en la lectura inferencial. Se evidencia que los aspectos como el clima del aula, aprendizaje cooperativo, aprender haciendo, aprendizaje significativo, las estrategias para la mediación de aprendizaje y los procesos metacognitivos en el proceso de aprendizaje son importantes para desarrollar la comprensión de la lectura. Asimismo, se consideran relevantes los elementos afectivos y sociales en el diseño de las estrategias. Por último, se concluye que más que consolidar la comprensión de la lectura, se consolidan los procesos cognitivos que posibilitan la comprensión. (shrink)

RESUMO: As novas tecnologias revolucionaram tanto as relações humanas quanto as formas de exploração. Com o uso massivo e a dependência das redes sociais, muitas pessoas descobriram fontes de ganhos fnanceiros a partir da exposição da imagem, seja da sua ou de outrem. Nesse cenário, a intimidade de centenas de crianças é exposta por seus pais ou responsáveis em troca de audiência, fama e recursos fnanceiros. Partindo dessa problemática, o presente artigo investiga os impactos do trabalho infantil mediante a exploração (...) da imagem e da intimidade da criança nas plataformas digitais. Por se tratar de uma nova modalidade de produção abundante de artistas mirins, suas consequências têm impactado a atual geração, sobretudo na saúde biopsicossocial. -/- PALAVRAS-CHAVE: Trabalho Infantil. Exposição Virtual. Exploração da Imagem. Redes Sociais. -/- ABSTRACT: New technologies have revolutionized both human relationships and forms of exploitation. With the massive use and dependence on social networks, many people have discovered sources of fnancial gain from the exposure of the image, whether theirs or someone else’s. In this scenario, the intimacy of hundreds of children is exposed by their parents or guardians in exchange for audience, fame and fnancial gain. Based on this problem, this article investigates the impacts of child labor through the exploitation of the image and intimacy of the child on digital platforms. As it is a new modality of abundant production of child artists, its consequences have impacted the current generation, especially in biopsychosocial health. -/- KEYWORDS: Child Labor.

The notion of a correct appreciation of nature, like the one put forward in Carlson’s environmental account, has been rejected by many other authors in the aesthetics of the natural environment. Their critics challenge the idea that only scientific cat- egories can ground the aesthetic appreciation of nature as nature, and they hold that there is not a correct way of appreciating nature. However, they may share with Carlson the idea of correctness under an objectivist paradigm of aesthetic appreciation, according (...) to which correctness means the adequation of the experi- ence to properties of the object. My aim in the article is to claim that it is necessary to endorse an aesthetic standard of correctness that takes into consideration the subjective character of aesthetic appreciation. An aesthetic standard of correct- ness implies universal assent, or validity for everyone in Kantian terms, in place of an objectivist notion. This notion of correctness permits the inclusion of expressive perception of nature as an essential form of aesthetic appreciation. (shrink)

Abstract: The refugee, migrant and human rights crisis ravaging the African continent through the Libyan coast is one that is self-inflicted, due in part and primarily so, a result of bad governance on the part of the African leaders who have not made the management and welfare of her citizens a primary and a going concern. Ethnic conflict and wars on resource control have also led to the forceful migration of some of these citizens from their homes. Thus, having been (...) frustrated and uncared for, dreams dashed and hope in the leaders lost, the average African citizen, in a bid to achieve their natural given potential have decided to seek alternative means to do so in other climes other than their home countries, no matter the cost. Using the documentary method of data collection and expost facto research design, the study found that the current crisis in Libya is largely a product of neglect by African leaders of their citizens and their seeming cluelessness in the ordering and direction of the lives of their citizens for individual, collective and societal growth. Apart from determining if the dearth of leadership was responsible for the current human rights crisis in Libya, the study also found that the average living conditions of African citizens was a probable cause. Thus, to properly understand the philosophical reason for the exodus of Africans out of their home countries, the study adopted the Neoclassical Migration Theory. The study finally recommends that African leaders should address the structural imbalance in their various domains that have sparked both internecine and genocidal conflict across the continent, and also ensure the implementation of the tenets of good and inclusive governance.

It was recommended, among others that, lecturers should practice the habit of managing research data in their personal computers and through manual channels. These records could become vital in the future for further problem-solving. (shrink)

There is currently an academic debate among researchers regarding the influence of age and gender on ICT utilisation generally among lecturers. This study was designed to contribute to this debate and open up new paths to areas on which researchers have focused little or no attention. This study examined lecturers’ variables (gender, age, educational qualification and rank) and the utilisation of ICT resources for teaching, research, and records management in higher education. The study adopted a descriptive survey design. The study’s (...) population comprised of 9,604 lecturers at the University of Calabar. A total of 313 lecturers who were available in their offices during data collection responded to a questionnaire which was designed by the researchers. Major findings showed that the extent of lecturers' utilisation of ICT for teaching, research, and records management is significantly low. Also, staff' educational qualification, rank, gender, and age significantly influence the utilisation of ICT for teaching, research and records management. Also, the utilisation of ICT resources decreased with lecturers’ educational qualifications, rank and age; male lecturers were more competent in the use of ICT resources than females. It was concluded that lecturers' variables play a significant role on the extent to which they utilise ICT resources for teaching, research and records management in higher education. This study creates a new path of innovation in education on which prospective researches could focus. (shrink)

The study developed and determined instant melon (Citrulluscolocynthis) soup powder’s shelf life for working-class mothers in Lagos, Nigeria. The study adopted research and development design. The population for the study was 2,077. The sample size for the study was 341. This consisted of three groups made up of 25 lecturers, 192 mothers working in banks and 124 mothers working. Seven sets of instruments were used for data collection. Data was analyzed using mean and standard deviation for the research questions. Findings (...) of the study indicated that the shelf life determinants included free fatty acid (FFA), moisture content and total viable count measured over a period of 22 weeks. From the analysis, FFA content slightly appreciated over the weeks; from 0.60 at the start to 0.7 5 at 4weeks; 0.86 at 8weeks; 0.95 at 12 weeks; 1.70 at 16 weeks and 4.06 at 22 weeks.

Quantum Mechanics is a fundamental physical theory about atomic-scale processes. It was built between 1920 and 1940 by the most distinguished physicists of that time. The accordance between the predictions of the theory and experimental results is remarkable. The physical interpretation of its mathematical constructs, however, raised unprecedented controversies. Ontological, semantic, and epistemic vagueness abound in the orthodox interpretations and have resulted in serious misunderstandings that are often repeated in textbooks and elsewhere. In this work, we identify, criticize, and clarify (...) the most spread ones. (shrink)

Some metaphysicians believe that metaphysical modality is explainable by the essences of objects. In §II, I spell out the definitional view of essence, and in §III, a working notion of metaphysical explanation. Then, in §IV, I consider and reject five natural ways to explain necessity by essence: in terms of the principle that essential properties can't change, in terms of the supposed obviousness of the necessity of essential truth, in terms of the logical necessity of definitions, in terms of Fine's (...) logic of essence, and in terms of the theory of real definitions. I will conclude that the present evidence favours rejecting the hypothesis that modality is explainable by essence. (shrink)

We present a deductive theory of space-time which is realistic, objective, and relational. It is realistic because it assumes the existence of physical things endowed with concrete properties. It is objective because it can be formulated without any reference to cognoscent subjects or sensorial fields. Finally, it is relational because it assumes that space-time is not a thing but a complex of relations among things. In this way, the original program of Leibniz is consummated, in the sense that space is (...) ultimately an order of coexistents, and time is an order of succesives. In this context, we show that the metric and topological properties of Minkowskian space-time are reduced to relational properties of concrete things. We also sketch how our theory can be extended to encompass a Riemannian space-time. (shrink)

We present an axiomatization of non-relativistic Quantum Mechanics for a system with an arbitrary number of components. The interpretation of our system of axioms is realistic and objective.

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My (...) analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science. (shrink)

On a highly influential way to think of modality, that I call ‘relationalism’, the modality of a state is explained by its being composed of properties, and these properties being related by a higher-order and primitively modal relation. Examples of relationalism are the Dretske-Tooley-Armstrong account of natural necessity, many dispositional essentialist views, and Wang’s incompatibility primitivism. I argue that relationalism faces four difficulties: that the selection between modal relations is arbitrary, that the modal relation cannot belong to any logical order, (...) that to explain how the modal relation can relate properties of different adicities additional ideological complexity has to be introduced, and that not all modal constraints are relational. From the discussion, I will extract desiderata for a successor theory of modality. (shrink)

This article aims to theoretically analyse so-called character friendship from the perspective of emotions. From this angle, our research enables us to distinguish different types of emotions, and we propose a conceptual model of the hierarchy of the emotions of character friendship and their influence on social behaviour. With this model in hand, the article discusses whether other-oriented emotions fully explain the emotional underpinnings of character friendship. We find other-oriented emotions to be ambiguous because they may or may not be (...) selfless. Thus we question whether these emotions can adequately explain the bonding content of character friendship. We conclude that there is a higher affective tier related to moral emotions and moral behaviour, which we have labelled the ‘bonding feeling’. This feeling is described with reference to its historical precedents (Rof Carballo’s ‘affective warp’), thus explaining its particularity. (shrink)

I present a discussion of some issues in the ontology of spacetime. After a characterisation of the controversies among relationists, substantivalists, eternalists, and presentists, I offer a new argument for rejecting presentism, the doctrine that only present objects exist. Then, I outline and defend a form of spacetime realism that I call event substantivalism. I propose an ontological theory for the emergence of spacetime from more basic entities. Finally, I argue that a relational theory of pre-geometric entities can give rise (...) to substantival spacetime in such a way that relationism and substantivalism are not necessarily opposed positions, but rather complementary. In an appendix I give axiomatic formulations of my ontological views. (shrink)

I present a formal ontological theory where the basic building blocks of the world can be either things or events. In any case, the result is a Parmenidean worldview where change is not a global property. What we understand by change manifests as asymmetries in the pattern of the world-lines that constitute 4-dimensional existents. I maintain that such a view is in accord with current scientific knowledge.

En México y en otros países, eufemísticamente llama-dos "en desarrollo", los sistemas públicos de atención a la salud enfrentan continuos recortes presupuestales, lo que impacta negativamente a los recursos materiales y a la disminución de plazas para los egresados de las carreras de medicina, esto es, menos contratos de médicos de base en hospitales, clínicas y centros de salud. Bajo este panorama adverso, algunos administradores, desarrolladores de software y no pocos políticos preclaros, suponen que la salida a los problemas económicos (...) estará en el uso intensivo de la inteligencia artificial (en adelante IA) y la robótica. Una vez que los algoritmos sean adecuadamente entrenados, un ejército de robots doctores serán capaces de hacer valoraciones más precisas, diagnósticos 100% acertados, y prescripciones farmacológicas exactas; mucho mejor que los médicos humanos. Además, la IA no se cansa, no protesta, no se sindicaliza… ¿Realidad o ficción? En países como China y el Reino Unido ya se utilizan técnicas computacionales para la interpretación de imágenes de rayos X, detección de tumores, prótesis inteligentes e incluso IA para predecir los resultados de un ataque cerebrovascular isquémico. En México se incorporó a RoomieBot, un robot que sirve para el diagnóstico de pacientes con posible coronavirus. La cirugía robótica Da Vinci es buen ejemplo de cómo la IA puede trabajar colaborativamente con la o el cirujano en el quirófano. Sin embargo, aún quedan por resolver grandes desafíos antes de preocuparse por el llamado desempleo tecnológico de los egresados. Si bien la IA es una valiosa herramienta, en estricto sentido, en esta y en otras muchas áreas su autonomía total es todavía una quimera, por ejemplo: los vehículos autónomos pueden ser engañados y hackeados, y no existe aún un robot que pueda hacer un simple nudo a las correas de sus zapatos sin asistencia 2. Por otra parte, se requiere un marco normativo-todavía inexistente-para la aplicación universal de IA en los cuidados de la salud. Los principios de la bioética están claramente establecidos: la beneficencia, la no maleficencia, la autonomía y la justicia, así como el Juramento Hipocrático. No es así para IA, donde los países interesados no llegan al consenso de los principios morales básicos de la medicina que debería extrapolar 3. Hasta que no se solucionen los problemas técnicos, tecnológicos y, sobre todo, los dilemas éticos, la IA deberá continuar como la útil herramienta que es para la medicina; sin embargo, sustituir el valor intrínseco kantiano de la persona es algo que, seguramente, tendremos mucho tiempo para reflexionar y, acaso, algún día resolver de manera satisfactoria.

The idea of a moving present or ‘now’ seems to form part of our most basic beliefs about reality. Such a present, however, is not reflected in any of our theories of the physical world. I show in this article that presentism, the doctrine that only what is present exists, is in conflict with modern relativistic cosmology and recent advances in neurosciences. I argue for a tenseless view of time, where what we call ‘the present’ is just an emergent secondary (...) quality arising from the interaction of perceiving self-conscious individuals with their environment. I maintain that there is no flow of time, but just an ordered system of events. (shrink)

Black holes are arguably the most extraordinary physical objects we know in the universe. Despite our thorough knowledge of black hole dynamics and our ability to solve Einstein’s equations in situations of ever increasing complexity, the deeper implications of the very existence of black holes for our understanding of space, time, causality, information, and many other things remain poorly understood. In this paper I survey some of these problems. If something is going to be clear from my presentation, I hope (...) it will be that around black holes science and metaphysics become more interwoven than anywhere else in the universe. (shrink)

This study focused specifically on determining the extent to which duration of vocational training influence university respectively. In achieving this, two research questions were raised and two research hypotheses were formulated to guide the study. The study adopted a descriptive survey design. The pop study include a total of 123 baking business and 208 computer business centres in the Area. Out of this population, a proportionate stratified sampling technique was used to select 10% resulting in the selection of 12 baking (...) and 21 computer adopted to select 36 and 63 graduate respectively, resulting in a sample of 99 respondents. A rating scale was used as the instrument for data collection. The instrument was administered by the researchers. The data obtained, were analysed using descriptive statistics, while the hypotheses were tested at .05 level of significance using one analysis of variance (One vocational training influenced university graduates job performance in baking and computer business enterprises respectively. Discussions, conclusion and recommendation were all made based on the findings of the study. (shrink)

A supertask consists in the performance of an infinite number of actions in a finite time. I show that any attempt to carry out a supertask will produce a divergence of the curvature of spacetime, resulting in the formation of a black hole. I maintain that supertaks, contrarily to a popular view among philosophers, are physically impossible. Supertasks, literally, collapse under their own weight.

The concept of ideology is central to the understanding of the many political, economic, social, and cultural processes that have occurred in the last two centuries. And yet, what is the nature of the different ideologies remains a vague, open, and much disputed question. Many political, sociological, and ideological studies have been devoted to ideology. Very little, on the other hand, has been done from the philosophical field. And this despite the fact that there are undoubtedly many philosophical questions related (...) to ideology and its role in modern industrialized societies. Just a few examples of ideology-related philosophical questions suffice to prove the point: What objects do ideologies deal with? Are the ideologies testable? Are there true ideologies? Do they evolve? How are ideologies related to societies? Is the existence of ideologies inevitable in modern societies? What is the relation of ideology to science? Is science just another kind of ideology? Are we, as human beings, innately predisposed to believe in ideologies? Or, instead, ideologies proliferate through indoctrination and propaganda? Are ideologies necessarily harmful?...and much more. In this article I try to answer some of these questions from a philosophical point of view, taking a materialist approach. I begin by characterizing ideology as a complex, multi-layered concept. Then, I briefly discuss the material systems on which ideological movements operate, that is, societies and concrete human groups. I identify at least 11 different elements that seem to be present in most ideologies, and I compare these characteristics with those of contemporary science and technology. Although some superficial similarities can be identified, there are deep differences that make ideology completely different from science. The similarities, however, are stronger with technology. Ideologies continually evolve with technological advances, social changes, and even with mere fashion. The current fragmentation of ideologies caused by the widespread use of new technologies and social networks has given rise to new phenomena of ideological propagation which, in my opinion, are very dangerous, particularly for open societies. I discuss these processes, within the context of the nature vs nurture debate, along with the question of whether we can get rid of ideologies. (shrink)

Los autores presentan los resultados de un estudio con la participación de 445 estudiantes, titulado: «La adquisición del inglés por medio de las clases en línea en estudiantes de nivel superior del Complejo Regional Nororiental durante la pandemia de COVID-19»; en él, entre otras conclusiones, proponen dinamizar la práctica digital y flexibilizar los métodos de evaluación, puesto que la 25 Introducción interacción social en el aprendizaje de una lengua extranjera es imperativa para motivar a los estudiantes.

I argue that there are no physical singularities in space–time. Singular space–time models do not belong to the ontology of the world, because of a simple reason: they are concepts, defective solutions of Einstein’s field equations. I discuss the actual implication of the so-called singularity theorems. In remarking the confusion and fog that emerge from the reification of singularities I hope to contribute to a better understanding of the possibilities and limits of the theory of general relativity.

Después de introducir el artículo (§1), repasaré los aspectos más generales y centrales de la literatura sobre la fundamentación (§2); esta tarea me parece valiosa ya que no existen revisiones generales y actualizadas en español sobre el tema. Después, argumentaré que la fundamentación no es una medida de complejidad física, y que, sin un vínculo necesario con la complejidad, quedan pocas razones para pensar que la fundamentación une a los diferentes estratos de la realidad física, que es una de las (...) motivaciones más importantes para introducir relaciones de dependencia (§3).

En The paradox of Addition and its dissolution (1969), Mario Bunge presenta algunos argumentos para mostrar que la Regla de Adición puede ocasionar paradojas o problemas semánticos. Posteriormente, Margáin (1972) y Robles (1976) mostraron que las afirmaciones de Bunge son insostenibles, al menos desde el punto de vista de la lógica clásica. Aunque estamos de acuerdo con las críticas de Margáin y Robles, no estamos de acuerdo en el diagnóstico del origen del problema y tampoco con la manera en la (...) que se proponen solucionarlo. En esta medida, en este texto mostraremos cómo la Regla de Adición sí trae problemas semánticos que pueden ser planteados desde diferentes perspectivas contemporáneas, como la extensionalidad del condicional, los principios proscriptivos y la validez conexiva.
