Fatimid history is considered one of the main periods of Islamic history in Egypt, so we cannot talk about the cultural metropolis of Egypt, the city of Cairo, without mentioning its founder, Jawhar al-Siqilli, the leader of the Fatimid Caliph al-Muizz Li-Din Allah al-Fatimid. The same is true of the Al-Azhar Mosque, which since its establishment until now has gained international fame in the Islamic world, throughout the historical stages, in addition to many of the Fatimid monuments scattered in Old (...) Cairo such as mosques, schools and alleys, all of this appears when talking about Egypt in general and Islamic Egyptin particular. The Fatimids sought to seize the Egyptian country a lot, as two military campaigns from North Africa to Egypt were launched, each of them failed. Then, the third campaign succeeded, led by Jawhar al-Siqilli, after the Fatimid Caliph al-Muizz prepared the equipment this time and arranged the army well, and had previously sent missionaries to this geography through the city of Alexandria and others, to herald the demise of the Ikhshidid state and the coming of the savior from this injustice and economic stagnation under which Egypt has fallen. He took several measures to try to declare Fatimid control over the Egyptian country. A delegation of the Egyptians sought to obtain a covenant from the Fatimid leader Jawhar al-Siqilli, to reassure them and remove their fears, especially with regard to their beliefs and religious matters. Indeed, the Fatimid leader issued this covenant, which included many things to reassure the Egyptians, among them that the Companions of the prophet are the most honorable people contrary to the famous Shiite belief- and that each will leave his belief, but it was not long before this covenant until many things were sealed. Our research here focuses on these matters.The research is divided into three main ponits: the first is the sectarian history of Egypt before the Fatimid occupation, and the second is the attempts to impose the Shiite sect on the Egyptians. The last point is the resistance or what hinders this imposition, and it is this last part that limited these influences to the Fatimid monuments such as buildings, mosques and schools. (shrink)

The Coronavirus pandemic has been ongoing for almost two years now. Not only did it surprise the whole world in the initial stages of its occurrence, but also the world left it in shock. Therefore, the instant solution strategies included complete lockdowns in order to prevent the spread of such a disease. However, as the lockdowns lasted longer, it generated negative psychological effects on people globally. This being the case, collective endeavors and efforts were performed, in the hope of achieving (...) a concrete solution in order to overcome the bad repercussions that seemed visible on societal levels, which of course, included religious aspects; and in some cases resulted in social separation as well as a dramatic rise in suicide rates. On the one hand, this caused a retraction from the religion and religiously oriented rituals, but on the other hand, it also made people turn more to religion as it provided a psychological relief from the heavy burdens of the pandemic. These psychological conditions had theological resonances that made already complicated issues even more complex. Among them, the nature of God’s actions and the human position in this matter can be given as examples. This article is an attempt to place and define the issue of the pandemics and plagues from the perspective of Islamic theology, in particular, to shed light on three main points. The first is the problem of pains and aches, and how it was mentioned in theological literaturey and discussed by Islamic theologians (Mutakallimūn), as the issue of pandemics and plagues indisputably fall under this matter. The second point tackles the problem of whether “such calamities as pandemics and plagues come from God's Decree, or not?”. The last point focuses on the issue of fatalism and tries to show whether the de facto acceptance that pandemics are from God’s Decree would require the servant to stop taking measures in response to them. To answer the questions at stake, this paper will focus on four different perspectives of the Mu’tazila, Ash‛arī s, Māturīdis, and Ahl al-Hadīth, by using a selective methodology and focusing on their prominent and pioneering theologians (Mutakallimūn) of these schools.

Diabetes mellitus (DM) is a colossal burden in global health, its prevalence increases steadily throughout the world. This systematic review explores the pathophysiology and epidemiology of diabetes, which describes the interactions that implicate that is the result of the play between genetic, environmental, and lifestyle factors in the development and progression of the disease. The review also describes a plethora of pharmacological treatments available to manage diabetes, with the oral agent, insulin regimens, and new approaches to therapy. Integrating the wisdom (...) of the best clinical guidelines, those are from American diabetes association (ADA), European association for the study of diabetes (EASD), and International Diabetes Federation (IDF). Since these reviews are consistent with normative standards for evidence-based recommendations of optimal care of diabetes. The review goes further to cover technological advances in the management of diabetes. They include Continuous Glucose Monitoring, advanced insulin delivery systems, and Artificial Pancreas Systems. Such technologies hold more promising routes to better glucose control and patient quality of life. All this comes along with challenges that their deployment and maintenance that run through economic, adherence issues, and unequal access to healthcare. The future research and innovation in the battle against DM will include the application of personalized medicine and the development of advanced digital health solutions. This article will become a treasure for health professionals, researchers, and policymakers who have dedicated themselves to battling the adversities of diabetes mellitus. (shrink)

We introduce tame abstract elementary classes as a generalization of all cases of abstract elementary classes that are known to permit development of stability-like theory. In this paper, we explore stability results in this new context. We assume that [Formula: see text] is a tame abstract elementary class satisfying the amalgamation property with no maximal model. The main results include:. Theorem 0.1. Suppose that [Formula: see text] is not only tame, but [Formula: see text]-tame. If [Formula: see text] and [Formula: (...) see text] is Galois stable in μ, then [Formula: see text], where [Formula: see text] is a relative of κ from first order logic. [Formula: see text] is the Hanf number of the class [Formula: see text]. It is known that [Formula: see text]. The theorem generalizes a result from [17]. It is used to prove both the existence of Morley sequences for non-splitting and the following initial step towards a stability spectrum theorem for tame classes:. Theorem 0.2. If [Formula: see text] is Galois-stable in some [Formula: see text], then [Formula: see text] is stable in every κ with κμ=κ. For example, under GCH we have that [Formula: see text] Galois-stable in μ implies that [Formula: see text] is Galois-stable in μ+n for all n < ω. (shrink)

Luck (2009) argues that gamers face a dilemma when it comes to performing certain virtual acts. Most gamers regularly commit acts of virtual murder, and take these acts to be morally permissible. They are permissible because unlike real murder, no one is harmed in performing them; their only victims are computer-controlled characters, and such characters are not moral patients. What Luck points out is that this justification equally applies to virtual pedophelia, but gamers intuitively think that such acts are not (...) morally permissible. The result is a dilemma: either gamers must reject the intuition that virtual pedophelic acts are impermissible and so accept partaking in such acts, or they must reject the intuition that virtual murder acts are permissible, and so abstain from many (if not most) extant games. While the prevailing solution to this dilemma has been to try and find a morally relevant feature to distinguish the two cases, I argue that a different route should be pursued. It is neither the case that all acts of virtual murder are morally permissible, nor are all acts of virtual pedophelia impermissible. Our intuitions falter and produce this dilemma because they are not sensitive to the different contexts in which games present virtual acts. (shrink)

We prove the following main theorem: Let be an abstract elementary class satisfying the joint embedding and the amalgamation properties with no maximal models of cardinality μ. Let μ be a cardinal above the the Löwenheim‐Skolem number of the class. If is μ‐Galois‐stable, has no μ‐Vaughtian Pairs, does not have long splitting chains, and satisfies locality of splitting, then any two ‐limits over M, for, are isomorphic over M.

Several lines of reasoning have been proposed to show the incompatibility of content externalism with justification internalism. In this paper I examine two such lines of reasoning, which both rely on the general idea that since content externalism is incompatible with certain aspects of the alleged privileged character of self-knowledge, it would tend to undermine justification internalism as well. I shall argue that both lines of reasoning, as they stand, lack plausibility, though the core idea of the second line can (...) be reconstructed into a new argument which shows considerable promise. In particular, relying upon the reliability constraint on knowledge, I shall argue that the so-called ‘two-concept’ version of content externalism is incompatible with ‘the transparency of sameness of content’, and thereby would also undermine justification internalism.

Coference papers from the X National Seminar of Theory and History of the Art carried out in Medellín to address certain implications that the question entails, for both art and philosophy.

At the heart of these questions is a basic (...) concern: Who needs more aesthetics (taste, pleasure, beauty): art or human life?. (shrink)

This article is aimed to rephrase and critique the arguments presented by Joseph LaPorte about the truth of theoretical identity statements in natural sciences. LaPorte is classified as an essentialist who accepts the real kinds, but he denies the essence of the kinds to be discovered. His arguments are based on the vagueness of the terms of kinds. In his view while science progress we convention (not discover) what is related to the kinds. I evaluate LaPorte's arguments and show they (...) can be applied only for the border terms in scientific theories and so the generalization of the claim is not defensible. (shrink)

A natural starting point for theories of perceptual states is ordinary perception, in which a subject is successfully related to her mind-independent surroundings. Correspondingly, the simplest theory of perceptual states models all such states on perception. Typically, this simple, common-factor relational view of perceptual states has received a perfunctory dismissal on the grounds that hallucinations are nonperceptual. But I argue that the nonperceptual view of hallucinations has been accepted too quickly. I consider three observations thought to support the view, and (...) argue that all three are dealt with equally well by an alternative view, illusionism, on which hallucinations do involve perception. Since this is so, adopting a common-factor relational view of all perceptual states remains a tenable option. (shrink)

Ibadiyya is one of the earliest Islamic sects and one of the few to have survived to the present day. The Ibadiyya sect is still active in many places, including Tanzania, the Sultanate of Oman, and North Africa. Despite all of this information, fewer studies on Ibadis exist than on other extant and non-member sects. An Islamic group known as the Ibadiyya first appeared following the so-called “great acts of sedition” (büyük fitne) in the first century AH. This group initially (...) supported the Kharijites, but over time, it gradually shifted away from them in terms of politics and mindset. Even though the Kharijites were exterminated from the historical scene at an early age, the Ibadis have survived until the present. However, according to many researchers, the Ibadis still exist as a branch of the Kharijites. In this study, the theological thoughts of North African Ibadis are discussed. Since the Ibadis and Kharijites generally held different ideological and political perspectives. And the North African Ibadis in particular are distinguished from the Kharijites as well as from the general Ibadis by their differences. And it is essential to understand the underlying and guiding thinking behind these differences in order to understand their essence. (shrink)

One of the main arguments intended to show that content externalism undermines the privileged access thesis is the ‘slow switching argument’, originally proposed by Boghossian. In this argument, it is supposed that a subject is unknowingly switched back and forth between Earth and Twin Earth: then it is claimed that, given externalism, when the subject is on Earth thinking that water is wet, he cannot know the content of his thought a priori, for he cannot, by mere reflection, rule out (...) the relevant alternative hypothesis that he is on Twin Earth thinking that twater is wet. One of the controversies surrounding this argument stems from the fact that it is not clear which epistemological principle underlies it. Here, I examine two suggestions made in the literature as to what that underlying principle might be. I argue that neither of these suggested principles is plausible, and thus that the slow switching argument never gets off the ground. (shrink)

Several recent accounts of modeling have focused on the modal dimension of scientific inquiry. More precisely, it has been suggested that there are specific models and modeling practices that are best understood as being geared towards possibilities, a view recently dubbed modal modeling. But modalities encompass much more than mere possibility claims. Besides possibilities, modal modeling can also be used to investigate contingencies, necessities or impossibilities. Although these modal concepts are logically connected to the notion of possibility, not all models (...) are equal in their affordances for these richer modal inferences. This paper investigates the modal extent of selected models and argues that analyzing singular model-target pairings by themselves is typically not enough to explain their modal aptness or to identify the kinds of modalities they can be used to reason about. Furthermore, it is argued that some important concepts that are not explicitly modal - like biological robustness - can be understood modally through their relational nature to a background space of possibilities. In conclusion, it is suggested that the strategy of modal modeling is contrastive, situating particular possibilities in larger modal spaces and studying the structural relations within them.

We present Saharon Shelah's Stability Spectrum and Homogeneity Spectrum theorems, as well as the equivalence between the order property and instability in the framework of Finite Diagrams. Finite Diagrams is a context which generalizes the first order case. Localized versions of these theorems are presented. Our presentation is based on several papers; the point of view is contemporary and some of the proofs are new. The treatment of local stability in Finite Diagrams is new.

Critics of multiple realizability have recently argued that we should concentrate solely on actual here-and-now realizations that are found in nature. The possibility of alternative, but unactualized, realizations is regarded as uninteresting because it is taken to be a question of pure logic or an unverifiable scenario of science fiction. However, in the biological context only a contingent set of realizations is actualized. Drawing on recent work on the theory of neutral biological spaces, the paper shows that we can have (...) ways of assessing the modal dimension of multiple realizability that do not have to rely on mere conceivability.

This paper recovers an important, century-old debate regarding the methodological and metaphysical foundations of dimensional analysis. Consideration of Richard Tolman's failed attempt to install the principle of similitude---the relativity of size---as the founding principle of dimensional analysis both clarifies the method of dimensional analysis and articulates two metaphysical positions regarding quantity dimensions. Tolman's position is quantity dimension fundamentalism. This is a commitment to dimensional realism and a set of fundamental dimensions which ground all further dimensions. The opposing position, developed primarily (...) by Bridgman, is quantity dimension conventionalism. Conventionalism is an anti-realism regarding dimensional structure, holding our non-representational dimensional systems have basic quantity dimensions fixed only by convention. This metaphysical dispute was left somewhat unsettled. It is shown here that both of these positions face serious problems: fundamentalists are committed to surplus dimensional structure; conventionalists cannot account for empirical constraints on our dimensional systems nor the empirical success of dimensional analysis. It is shown that an alternative position is available which saves what is right in both: quantity dimension functionalism. (shrink)

The gamer’s dilemma offers three plausible but jointly inconsistent premises: (1) Virtual murder in video games is morally permissible. (2) Virtual paedophelia in video games is not morally permissible. (3) There is no morally relevant difference between virtual murder and virtual paedophelia in video games. In this paper I argue that the gamer’s dilemma can be understood as one of three distinct dilemmas, depending on how we understand two key ideas in Morgan Luck’s (2009) original formulation. The two ideas are (...) those of (1) occurring in a video game and (2) being a virtual instance of murder or paedophelia. Depending on the weight placed on the gaming context, the dilemma is either about in-game acts or virtual acts. And depending on the type of virtual acts we have in mind, the dilemma is either about virtual representations or virtual partial reproductions of murder and paedophelia. This gives us three dilemmas worth resolving: a gaming dilemma, a representation dilemma, and a simulation dilemma. I argue that these dilemmas are about different issues, apply to different cases, and are susceptible to different solutions. I also consider how different participants in the debate have interpreted the dilemma in one or more of these three ways. (shrink)

Shelah's 1980 paper Simple unstable theories. The concept of weak dividing has been replaced with that of forking. The exposition is from a contemporary perspective and takes into account contributions due to S. Buechler, E. Hrushovski, B. Kim, O. Lessmann, S. Shelah and A. Pillay.

In this paper a symmetry argument against quantity absolutism is amended. Rather than arguing against the fundamentality of intrinsic quantities on the basis of transformations of basic quantities, a class of symmetries defined by the Π-theorem is used. This theorem is a fundamental result of dimensional analysis and shows that all unit-invariant equations which adequately represent physical systems can be put into the form of a function of dimensionless quantities. Quantity transformations that leave those dimensionless quantities invariant are empirical and (...) dynamical symmetries. The proposed symmetries of the original argument fail to be both dynamical and empirical symmetries and are open to counterexamples. The amendment of the original argument requires consideration of the relationships between quantity dimensions. The discussion raises a pertinent issue: what is the modal status of the constants of nature which figure in the laws? Two positions, constant necessitism and constant contingentism, are introduced and their relationships to absolutism and comparativism undergo preliminary investigation. It is argued that the absolutist can only reject the amended symmetry argument by accepting constant necessitism. I argue that the truth of an epistemically open empirical hypothesis would make the acceptance of constant necessitism costly: together they entail that the facts are nomically necessary. (shrink)

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law. It searches for a curative for the pathological transformation of these institutions into--so called--political religions. Along this line, it explores the importance of spirituality and transcendence for political legitimacy, democratic participation and international cooperation, law and politics. There being no general agreed-upon definition of 'spirituality', the authors examine what may (...) be seen as 'spiritual' dimensions of the political. These dimensions have in common a focus on transcendence as a vanishing point of rationality and rational justification. This vanishing point may become manifest, for example, in a primordial requisite of becoming an individual person; in responding--in freedom--to the call of theocracy; in the phenomenon of prophecy or political wisdom; in the remaining shards of formerly all-pervasive religious institutions; in tenacious hope for a democracy-to-come; in the courageous resilience and resistance of citizens of 'non-' or 'un-democratic' states; etc."--Page 4 of back cover.

Ubuntu has been defined as a moral quality of human beings, as a philosophy or an ethic, as African humanism, and as a worldview. This paper explores these definitions as conceptual tools for understanding the cultural, educational, and philosophical landscape of post-apartheid South Africa. Key to this understanding is the Althusserian concept of state apparatus. Louis Althusser divides the state apparatus into two forces: the repressive state apparatus (RSA); and the ideological state apparatus (ISA). RSAs curtail the working classes, predominately (...) through direct violence or the threat of violence, whereas ISAs function primarily by ideology, including forms of organised religion, the education system, family units, legal systems, trade unions, political parties, and media. This paper discusses the link between increasing inequality in post-apartheid South Africa and education, with specific reference to Althusser’s ISAs and the abuse of Ubuntu as a subterfuge for socio-economic inequality.

How do we assign values to virtual items, which include virtual objects, properties, events, subjects, worlds, environments, and experiences? In this article, I offer a framework for answering this question. After considering different value theses in the literature, I argue that whether we think these theses mutually exclusive or not turns on our view about the number of value-salient kinds virtual items belong to. Virtual monism is the view that virtual Xs belong to only one value-salient kind in relation to (...) X. Virtual pluralism is the view that they belong to more than one value-salient kind. I argue for two claims. First, virtual monism is mistaken. Minimally some virtual Xs are Xs, while others are not. Second, dualistic virtual pluralism is also mistaken because it is too coarse grained. Instead, I argue for fourfold pluralism: virtual items either represent an original's properties or reproduce essential properties and do so to lesser or greater extents. This gives us four value-salient kinds of virtual X: virtual reproductions, simulations, representations, and simulacra of X. I apply this view to various debates in the literature and conclude with a discussion of less basic hybrid kinds. (shrink)

Many scientific models in biology are how-possibly models. These models depict things as they could be, but do not necessarily capture actual states of affairs in the biological world. In contemporary philosophy of science, it is customary to treat how-possibly models as second-rate theoretical tools. Although possibly important in the early stages of theorizing, they do not constitute the main aim of modelling, namely, to discover the actual mechanism responsible for the phenomenon under study. In the paper it is argued (...) that this prevailing picture does not do justice to the synthetic strategy that is commonly used in biological engineering. In synthetic biology, how-possibly models are not simply speculations or eliminable scaffolds towards a single how-actually model, but indispensable design hypotheses for a field whose ultimate goal is to build novel biological systems. The paper explicates this by providing an example from the study of alternative genetic systems by synthetic biologist Steven Benner and his group. The case will also highlight how the method of synthesis, even when it fails, provides an effective way to limit the space of possible models for biological systems. (shrink)

Let M be a given model with similarity type L = L(M), and let L' be any fragment of L |L(M)| +, ω of cardinality |L(M)|. We call $N \prec M L'$ -relatively saturated $\operatorname{iff}$ for every $B \subseteq N$ of cardinality less than | N | every L'-type over B which is realized in M is realized in M is realized in N. We discuss the existence of such submodels. The following are corollaries of the existence theorems. (1) If (...) M is of cardinality at least $\beth_{\omega_1}$ , and fails to have the ω order property, then there exists $N \prec M$ which is relatively saturated in M of cardinality $\beth_{\omega_1}$ .

Given the evolution of the public health (PH) and the changes from the phenomenon of globalization, this area has encountered new ethical challenges. In order to find a coherent approach to address ethical issues in PH policy, this study aimed to identify the evolution of public health ethics (PHE) frameworks and the main moral values and norms in PH practice and policy. According to the research questions, a systematic search of the literature, in English, with no time limit was performed (...) using the main keywords in databases Web of Science (ISI) and PubMed. Finally, the full text of 56 papers was analyzed. Most of the frameworks have common underpinning assumptions and beliefs, and the need to balance PH moral obligation to prevent harm and health promotion with respect for individual autonomy has been specified. As such, a clear shift from liberal values in biomedical ethics is seen toward the community’s collective values in PHE. The main moral norms in PH practice and policy included protecting the population against harm and improving PH benefits, utility and evidenced-based effectiveness, distributive justice and fairness, respect for all, privacy and confidentiality, solidarity, social responsibility, community empowerment and participation, transparency, accountability and trust. Systematic review of PHE frameworks indicates utilization of the aforementioned moral norms through an practical framework as an ethical guide for action in the PH policy. The validity of this process requires a systematic approach including procedural conditions. (shrink)

A widely held assumption is that hallucinations are not a type of perception. Coupled with the idea that hallucinations possess phenomenal character, this assumption raises a problem for naive realism, which maintains that phenomenal character is at least partly constituted by perceived worldly objects. Naive realists have typically responded by adopting a disjunctive view of phenomenal character. But in what follows, I argue that to resolve the conflict we should instead reject the idea that hallucinations are not a type of (...) perception. I argue that this idea is supported by six alleged differences between hallucination and perception, but these differences are all accommodated for in a particular type of perception, picture perception. Drawing on picture perception’s resources, I offer an account of hallucinations which construes them as a type of perception, and does so in a way that that preserves their idiosyncrasies and varieties, and in a way compatible with naive realism.

Abstract: Tomatoes are part of the major crops in food security. Tomatoes are plants grown in temperate and hot regions of South American origin from Peru, and then spread to most countries of the world. Tomatoes contain a lot of vitamin C and mineral salts, and are recommended for people with constipation, diabetes and patients with heart and body diseases. Studies and scientific studies have proven the importance of eating tomato juice in reducing the activity of platelets in diabetics, which (...) helps in protecting them from developing deadly blood clots. A tomato classification approach is presented with a data set containing approximately 5,266 images with 7 species belonging to tomatoes. The Neural Network Algorithms (CNN), a deep learning technique applied widely in image recognition, is used for this task. (shrink)

Our sense of entitlement influences our interactions and attitudes in a range of specific relational contexts, one of them being aging parents’ relationships with their adult children. This study aimed to examine the factor structure of the Sense of Relational Entitlement—aging parents toward their offspring, an 11-item questionnaire that assesses aging people’s sense of relational entitlement toward their children, and examine the associations of its subscales with related personality and mental health constructs. One thousand and six participants, aged 65–99, with (...) at least one child, completed the SRE-ao, Brief Symptom Inventory, Loneliness Scale, and General Belongingness scale. The SRE-ao demonstrated good construct structure using confirmatory factor analysis. Both SRE-ao subscales were significantly and positively associated with anxiety, depression, somatization and sense of loneliness and negatively with sense of belonging. When all variables were entered into a regression model, age, anxiety, and low sense of belonging, but not sense of loneliness, positively predicted both restricted and inflated sense of entitlement. Somatization negatively predicted inflated sense of entitlement. The SRE-ao is a reliable and valid scale that can be used in clinical practice and research to enhance our understanding of parent–child relationships throughout the lifespan. (shrink)

Norms provide a valuable mechanism for establishing coherent cooperative behaviour in decentralised systems in which there is no central authority. One of the most influential formulations of norm emergence was proposed by Axelrod :1095–1111, 1986). This paper provides an empirical analysis of aspects of Axelrod’s approach, by exploring some of the key assumptions made in previous evaluations of the model. We explore the dynamics of norm emergence and the occurrence of norm collapse when applying the model over extended durations. It (...) is this phenomenon of norm collapse that can motivate the emergence of a central authority to enforce laws and so preserve the norms, rather than relying on individuals to punish defection. Our findings identify characteristics that significantly influence norm establishment using Axelrod’s formulation, but are likely to be of importance for norm establishment more generally. Moreover, Axelrod’s model suffers from significant limitations in assuming that private strategies of individuals are available to others, and that agents are omniscient in being aware of all norm violations and punishments. Because this is an unreasonable expectation, the approach does not lend itself to modelling real-world systems such as online networks or electronic markets. In response, the paper proposes alternatives to Axelrod’s model, by replacing the evolutionary approach, enabling agents to learn, and by restricting the metapunishment of agents to cases where the original defection is observed, in order to be able to apply the model to real-world domains. This work can also help explain the formation of a “social contract” to legitimate enforcement by a central authority. (shrink)

Freges Konzeption der Existenz zählt zu seinen einflussreichsten und originellsten Beiträgen zur Philosophie.

A central debate in the philosophy of virtual reality (VR) focuses on the reality of virtual items. Broadly, there are two main disagreements. Some views accept a metaphysical orientation to VR, and disagree on the reality of virtual items. For instance, David Chalmers (Disputatio 9(46):309-352, 2017, Disputatio 11(55):453- 486, 2019, 2022) defends digitalism, the view that virtual items are real digital items. Neil McDonnell & Nathan Wildman (Disputatio 11(55):371-397, 2019), by contrast, defend fictionalism, which maintains that virtual items are unreal (...) fictions. Other views, like Grant Tavinor’s (2021), reject the metaphysical orientation, argu- ing that focusing on the reality of virtual items is a mistake. In what follows I evalu- ate these two disagreements. I argue that experiences of virtual items depend on episodes of picture perception. Recognizing this reveals that the current debates are either easily resolved in favor of one view, or are not disagreeing about the reality of virtual items, but about what virtual items are.

In many areas, technology has facilitated many things, diagnosing diseases, regulating traffic and teaching students in schools rely on Intelligent systems to name a few. At present, traditional classroom-based education is no longer the most appropriate in schools. From here, the idea of intelligent e-learning for students to increase their culture and keep them updated in life began. E-learning has become an ideal solution, relying on artificial intelligence, which has a footprint in this through the development of systems based on (...) education without a teacher taking into account the individual differences of students. This study describes intelligent tutoring system for teaching the Data Manipulation Language (DML) Commands Using SQLite to non IT students to overcome the difficulties they face. The System was built as education system by using the researcher own authoring tool that based on mobile and web App. The basic idea of this system is a systematic introduction into the concept of Database and its DML query. The system presents the topic of DML Commands, help student to execute what they are learn from the system content using the practical part of the system and administers automatically adapted at run time to the student’s individual growth. The system was assessed by a group of teachers and students and the outcome showed as 91% from the database specialists, 94% from Diploma students group and 89% from the secondary school students group.

Along the lines of a previous work, the geometrical structure of Hibert bundles describing extended quantum free particles is repeated with Galilei external and internal independent symmetries. Then, in order to introduce the interaction, this structure is extended by replacing configuration and momentum spaces by the socelled spaces of trajectories and extended velocity boosts, respectively. These provide representations giving the probability amplitudes for the particle to follow certain trajectories. The interaction can be introduced in the transformation law from functions on (...) the space of trajectories (free dynamics) to functions on spacetime (intracting dynamics). This transformation law, which makes use of a universal distribution, is seen as a functional in our work according to a quantum functional theory which generalizes the ideas of de Broglie. Intertwining of induced representations gives the free propagator in the space of trajectories and, henceforth, the propagator with interaction in space-time for the extended particle. (shrink)
