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.

Scholars studying the global diffusion of “corporate social responsibility” (CSR) practices and the associated rise of privatized forms of economic governance have tended to shift attention away from the role of corporations in motivating these processes to the one played by nonbusiness forces seeking social control of corporations. We bring corporate power back in by turning the spotlight to the agency of business classes, the business entities capable of pursuing transcorporate, societal-level, macro-political endeavors. Building on a comparative investigation of two (...) of the world’s earliest mass CSR adoptions, in postwar Venezuela and Britain, we argue that business classes responding to anti-capitalist challenges were the original diffusers of CSR practices and, interrelatedly, promoters of CSR-based, privatized forms of regulation and governance. Organized by peak business associations, the purpose of these “business-class CSR mobilizations” was to weaken the state in its relation to corporations and increase the control of business over social trends. We discuss the contribution of our historical perspective and analytical approach to a more complete and balanced picture of the global rise of CSR in late capitalism. (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)

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)

The Oracle Intelligent Tutoring System (OITS) examined the power of a new methodology to supporting students in Oracle programming. The system presents the topic of Introduction to Oracle with automatically generated problems for the students to solve. The system is dynamically adapted at run time to the student’s individual progress. An initial evaluation study was done to investigate the effect of using the intelligent tutoring system on (...) the performance of students. (shrink)

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.

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)

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)

Un paralelismo antitetico le da forma a los fragmentos de los Pensamientos de Blaise Pascal, al prolongar el movimiento paradojico de la naturaleza humana desde el divertissement hasta los porticos de la conversion. En el primer foco de la figura, la diversion, contemplada de un modo alegorico, por la cual el hombre se aleja de Dios y hace del mundo el objeto de su concupiscencia. En el otro foco, la conversion, en la que el hombre se aleja del mundo y (...) se vuelve a Dios merced a un movimiento de la Gracia. La concupiscencia es el enves del orden de la Caridad, como el divertimento es el reverso de la partida que abre a la fe cristiana. Las paginas de este libro retratan el trayecto del unico jugador y dan razon de la complejidad de su existencia, que se debate entre el tedio, la angustia ante la muerte y el riesgo de una apuesta en la que la libertad empena el todo de su nada en vistas a una ganancia infinita.

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)

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)

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.

Recently, several critics of the multiple realizability thesis have argued that philosophers have tended to accept the thesis on too weak grounds. On the one hand, the analytic challenge has problematized how philosophers have treated the multiple realization relation itself, claiming that assessment of the sameness of function and the relevant difference of realizers has been uncritical. On the other hand, it is argued that the purported evidence of the thesis is often left empirically unverified. This paper provides a novel (...) strategy to answer these worries by introducing a role for multiple realizability in the context of biological engineering. In the field of synthetic biology, bioengineers redesign the evolutionary realizations of biological functions, even constructing artificial chemical surrogates in the laboratory. I show how in the rational design approach to biological engineering, multiple realizability can function as a design heuristic in which the sameness of function and difference of realizers can be controlled. Although practically motivated, this engineering approach has also a theoretical, exploratory component that can be used to study the empirical limitations of multiple realizability. Successful realization of the engineering designs would amount to a concrete demonstration of multiple realizability, taking evidence for MRT beyond what is readily found in nature. (shrink)

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 promotes critical realism as a suitable and fruitful philosophical foundation for the development and implementation of urban digital twins. The proliferation of a-theoretical digital twin research and practices, not declaring their philosophical positions, is threatening the scientific soundness of this new paradigm and offers little evidence for reflecting on the knowledge it produces. To address this issue, first, this paper uses focus group discussions to explore digital twin experts’ perceptions of digital twin best practices for urban management and (...) uncover the philosophical worldviews underlying these perceptions. A philosophical worldview is a general orientation about the world that is described in terms of ontological and epistemological assumptions and views on human nature. The inferred philosophical worldviews are then compared with critical realism principles, supporting the argument that critical realism provides a suitable philosophical foundation for digital twin practices in urban management envisaged by participating experts, as well as enhancing current forms of digital twin practice.

We present a self-contained exposition of the basic aspects of simple theories while developing the fundamentals of forking calculus. We expound also the deeper aspects of S. 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.

Besides having potential medical and biosafety applications, as well as challenging the foundations of biological engineering, xenobiology can also shed light on the epistemological and metaphysical questions that puzzle philosophers of science. This paper reviews this philosophical aspect of xenobiology, focusing on the possible multiple realizability of life. According to this hypothesis, what ultimately matters in understanding life is its function, not its particular building blocks. This is because there should, in theory, be many different ways to build the same (...) function. The possibility of multiple realizability was originally raised in the context of AI’s hypothesized capacity to realize mental functions. Because we still do not have any incontrovertible examples of digital minds, not to mention alien life of foreign biochemistry, the best way to test this philosophical idea is to examine the recent results and practices of synthetic biology and xenobiology.

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. For art: Why and since when do we think that art without aesthetics is something reprehensible or desirable? For philosophy: Is it irremovable or not the turn that the philosophical aesthetic took towards the experience of art from the eighteenth century? At the heart of these questions is a basic (...) concern: Who needs more aesthetics (taste, pleasure, beauty): art or human life?. (shrink)

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)
