A los cristales se los describe como a una red de átomos que puede vibrar alrededor de su posición de equilibrio. Sin embargo, el hecho de que la energía de estas ondas esté cuantificada sugiere una analogía con el campo electromagnético. En analogía con el fotón se define al fonón. Generalmente se concibe al fonón como a una cuasi-partícula, es decir, como a un instrumento matemático útil en los cálculos pero sin una existencia propia. En este trabajo estudiamos el estatuto (...) ontológico del fonón y argumentaremos en favor de la idea de considerarlo como una partícula real. (shrink)

La interpretación modal-hamiltoniana fue introducida para resolver ciertos problemas de interpretación vinculados a su ontología y a la medición cuántica. Su regla de actualización establece que todo sistema cerrado tiene su energía bien definida, y debido a la indeterminación entre la energía y el tiempo esto plantea un interrogante respecto a la situación temporal de estos sistemas. En este trabajo se analiza el problema del tiempo en sistemas cerrados y se propone la reconstrucción de un tiempo relacional compatible con la (...) perspectiva holista. (shrink)

En los últimos años, el comportamiento bosónico que un sistema de fermiones puede exhibir ha despertado el interés de los físicos. En este trabajo, se adopta un enfoque basado en estructuras producto tensorial y se asume una ontología de propiedades para argumentar en favor de la relatividad de la noción de identidad estadística y en favor de una interpretación realista del comportamiento trans-estadístico.

En este trabajo se discuten los problemas que se presentan en el modelo de medición basado en decoherencia. Debido a que el origen de las críticas a este modelo se encuentra en el uso de los estados reducidos de sistemas abiertos, se propone un cambio de enfoque. Por un lado, la adopción de la perspectiva de los sistemas cerrados permite dar cuenta de procesos irreversibles en sistemas que no interactúan con un ambiente. Por otro lado, el enfoque de los valores (...) medios hace posible el estudio de la evolución de los sistemas cuánticos sin apelar a sus estados. La combinación de ambos enfoques da como resultado una formulación de la decoherencia cuántica, cuya aplicación al problema de la medición supera las críticas del enfoque original. (shrink)

Normativity is assessed as we evaluate and compare the environmental reporting practices of a sample of French and Canadian companies through the lens of institutional legitimacy. More specifically, we examine how French and Canadian firms changed their reporting practices in reaction to the promulgation of laws and regulations in their respective countries, i.e., the NER and Grenelle II Acts in France, and National Instrument 51-102 and CSA Staff Notice NR 51-333, issued by the Canadian Securities Administrators. The firms’ voluntary disclosures (...) according to GRI guidelines are also investigated. Substantive legitimacy theory is used to explore the level of substantive disclosures provided by Canadian and French firms. The findings reveal that the French parliamentary regime is more successful than the Canadian stock exchange regulation in triggering environmental reporting, and that the GRI combined with local regimes prompts environmental disclosures. Notwithstanding the improvements in environmental reporting under all three regimes, a very low level of substantive disclosure is noted in both countries. (shrink)

Perhaps the hottest topic in the philosophy of chemistry is that of the relationship between chemistry and physics. The problem finds one of its main manifestations in the debate about the nature of molecular structure, given by the spatial arrangement of the nuclei in a molecule. The traditional strategy to address the problem is to consider chemical cases that challenge the definition of molecular structure in quantum–mechanical terms. Instead of taking that top-down strategy, in this paper we face the problem (...) of the reduction of molecular structure to quantum mechanics from a bottom-up perspective: our aim is to show how the theoretical peculiarities of quantum mechanics stand against the possibility of molecular structure, defined in terms of the spatial relations of the nuclei conceived as individual localized objects. We will argue that, according to the theory, quantum “particles” are not individuals that can be identified as different from others and that can be reidentified through time; therefore, they do not have the ontological stability necessary to maintain the relations that can lead to a spatially definite system with an identifiable shape. On the other hand, although quantum chemists use the resources supplied by quantum mechanics with successful results, this does no mean reduction: their “approximations” add certain assumptions that are not justified in the context of quantum mechanics or are even inconsistent with the very formal structure of the theory.

The study of ethical decision-making has made significant advances, particularly with regard to the ways in which different types of processing are implicated. In recent decades, much of this advancement has been driven by the influence of dual-process theories of cognition. Unfortunately, the wealth of findings in this context can be confusing for management scholars and practitioners who desire to know how best to encourage ethical behavior. While some studies suggest that deliberate reflection leads to more ethical behavior, other studies (...) find, in contrast, that intuitive decision-making leads to more ethical results. The goal of this integrative conceptual review is to help make sense of such apparently contradictory findings by identifying the moderating influences that lead to more versus less ethical decisions, whether they are made via intuitive or deliberative processes. Based on our integrative review of moderators from different disciplines and eras, we develop a taxonomy that can aid researchers in the task of identifying when similar constructs have been studied under different names. We organize our findings concerning these influences in accordance with four emergent moderator categories—psychological, situational, social, and physiological. This work helps us identify patterns of moderating factors across both intuitive and deliberative ethical decision-making, gaps that suggest future research directions and practical implications.

The difficult issues related to the interpretation of quantum mechanics and, in particular, the “measurement problem” are revisited using as motivation the process of generation of structure from quantum fluctuations in inflationary cosmology. The unessential mathematical complexity of the particular problem is bypassed, facilitating the discussion of the conceptual issues, by considering, within the paradigm set up by the cosmological problem, another problem where symmetry serves as a focal point: a simplified version of Mott’s problem.

Management scholars and social scientists investigate dynamics of subjective fairness perceptions in the workplace under the umbrella term “organizational justice.” Philosophers and ethicists, on the other hand, think of justice as a normative requirement in societal relationships with conflicting interests. Both ways of looking at justice have neither remained fully separated nor been clearly integrated. It seems that much could be gained and learned by more closely integrating the ethical and the empirical fields of justice. On the other hand, it (...) may simply not be possible to bridge the divide between the subjective empirical and the normative prescriptive justice as both fields pose different questions and rely on different assumptions and methods. In this paper, we propose a “reconciliation” model, as a third way of considering justice in the workplace, taking into account normative and psychological issues pertaining to justice. Through applying a reconciliation model, we provide a new way of looking at the interconnections between justice philosophy and organizational justice that could advance future research in both fields. Our model also implies that justice researchers can and should be concerned with the moral implications of their own subject of research. (shrink)

People react negatively not only to injustices they personally endure but also to injustices that they observe as bystanders at work—and typically, people observe more injustices than they personally experience. It is therefore important to understand how organizations can restore observers’ perceptions of justice after an injustice has occurred. In our paper, we employ a policy capturing design to test and compare the restorative power of monetary compensation, procedure changes and apologies, alone and in combination, from the perspective of third (...) parties. We extend previous research on remedies by including different degrees of compensation and procedural changes, by comparing the effects of sincere versus insincere apologies and by including apologies from additional sources. The results indicate that monetary compensation, procedure changes, and sincere apologies all have a significant and positive effect on how observers perceive the restoration of justice. Insincere apologies, on the other hand, have no significant effect on restoration for third parties. Procedural changes were found to have the strongest remedial effects, a remedy rarely included in previous research. One interpretation of this finding could be that observers of injustice prefer solutions that are not short sighted: changing procedures avoids future injustices that could affect other people. We found that combinations of remedies, such that the presence of a second remedy strengthens the effect of the first remedy, are particularly effective. Our findings regarding interactions underline the importance of studying and administering remedies in conjunction with each other. (shrink)

Some authors, inspired by the theoretical requirements for the formulation of a quantum theory of gravity, proposed a relational reconstruction of the quantum parameter-time—the time of the unitary evolution, which would make quantum mechanics compatible with relativity. The aim of the present work is to follow the lead of those relational programs by proposing a relational reconstruction of the event-time—which orders the detection of the definite values of the system’s observables. Such a reconstruction will be based on the modal-Hamiltonian interpretation (...) of quantum mechanics, which provides a clear criterion to select which observables acquire a definite value and to specify in what situation they do so.

In the last years, the surprising bosonic behavior that a many-fermion system may acquire has raised interest because of theoretical and practical reasons. This trans-statistical behavior is usually considered to be the result of approximation modeling methods generally employed by physicists when faced with complexity. In this paper, we take a tensor product structure and an ontology of properties approach and provide two versions of a toy model in order to argue that trans-statistical behavior allows for a realistic interpretation.

This study aimed to identify the learning and business incubation processes and their impact on developing the performance of business incubators in Gaza Strip, and the study relied on the descriptive analytical approach, and the study population consisted of all employees working in business incubators in Gaza Strip in addition to experts and consultants in incubators where their total number reached (62) individuals, and the researchers used the questionnaire as a main tool to collect data through the comprehensive survey method, (...) where (55) questionnaires were retrieved with a recovery rate of (88.7%). The results of the study showed that there is a high approval of the variables of the study, where the dimension of incubation operations came with a relative weight (84.89%), followed by the learning dimension which got a relative weight (82.50%), while the performance level of the incubators got a relative weight (80.12%) and as the study results showed There is a positive relationship statistically between the two dimensions of learning and business incubation processes and performance development in business incubators, and the linear regression analysis model showed that the main effect in improving the performance of business incubators is "after business incubation operations" while it showed weak effect after learning. The study came out with several recommendations, the most important of which is that business incubators seek to reinforce the learning process and incubation processes for business, and the need to periodically evaluate their performance, and that a more effective mechanism be designed to follow up with companies after the end of the incubation period and monitor the progress of these companies.

We discuss generalized pobabilistic models for which states not necessarily obey Kolmogorov's axioms of probability. We study the relationship between properties and probabilistic measures in this setting, and explore some possible interpretations of these measures.

Christopher Timpson proposes a deflationary view about information, according to which the term ‘information’ is an abstract noun and, as a consequence, information is not part of the material contents of the world. The main purpose of the present article consists in supplying a critical analysis of this proposal, which will lead us to conclude that information is an item even more abstract than what Timpson claims. From this view, we embrace a pluralist stance that recognizes the legitimacy of different (...) interpretations of the concept of information. (shrink)

BackgroundThe overwhelming scarcity of organs within renal transplantation forces researchers and transplantation teams to seek new ways to increase efficacy. One of the possibilities is the use of personalized medicine, an approach based on quantifiable and scientific factors that determine the global immunological risk of rejection for each patient. Although this approach can improve the efficacy of transplantations, it also poses a number of ethical questions.MethodsThe qualitative research involved 22 semi-structured interviews with nephrologists involved in renal transplantation, with the goal (...) of determining the professionals' views about calculating the global immunological risk and the attendant ethical issues.ResultsThe results demonstrate a general acceptance of this approach amongst the participants in the study. Knowledge of each patient's immunological risk could improve treatment and the post-graft follow-up. On the other hand, the possibility that patients might be excluded from transplantation poses a significant ethical issue. This approach is not seen as something entirely new, given the fact that medicine is increasingly scientific and evidence-based. Although renal transplantation incorporates scientific data, these physicians believe that there should always be a place for clinical judgment and the physician-patient relationship.ConclusionsThe participants see the benefits of including the calculation of the global immunological risk within transplantation. Such data, being more precise and rigorous, could be of help in their clinical work. However, in spite of the use of such scientific data, a place must be retained for the clinical judgment that allows a physician to make decisions based on medical data, professional expertise and knowledge of the patient. To act in the best interests of the patient is key to whether the calculation of the global immunological risk is employed. (shrink)

Recent discussions about the microstructure of materials generally focus on the ontological aspects of the molecular structure. However, there are many types of substances that cannot be studied by means of the concept of molecule, for example, salts. For the quantum treatment of these substances, a new particle, called phonon, is introduced. Phonons are generally conceived as a pseudo-particle, that is, a mathematical device necessary to perform calculations but which does not have a “real” existence. In this context, the aim (...) of this paper will be to analyze the ontological status of phonons. For such purposes we will critically analyze the arguments that would account for the presumed nonexistence of phonons. Finally, having already demonstrated that there are not enough reasons to consider phonons as non-existing entities, we will explore some possibilities that allow us to elucidate their ontological status.

In the present paper we address the problem of optical isomerism embodied in the socalled “Hund’s paradox”, which points to the difficulty to account for chirality by means of quantum mechanics. In particular, we explain the answer to the problem proposed by the theory of decoherence. The purpose of this article is to challenge this answer on the basis of a conceptual analysis of the phenomenon of decoherence, that reveals the limitations of the theory of decoherence to solve the difficulties (...) posed by optical isomerism and, in general, by quantum measurement.

According to the environment-induced approach to decoherence, the split of the Universe into the degrees of freedom which are of direct interest to the observer and the remaining degrees of freedom is absolutely essential for decoherence. However, the EID approach offers no general criterion for deciding where to place the “cut” between system and environment: the environment may be “external” or “internal”. The main purpose of this paper is to argue that decoherence is a relative phenomenon, better understood from a (...) closed-system perspective according to which the split of a closed quantum system into an open subsystem and its environment is just a way of selecting a particular space of relevant observables of the whole closed system. In order to support this claim, we shall consider the results obtained in a natural generalization of the simple spin-bath model usually studied in the literature. Our main thesis will lead us to two corollaries. First, the problem of identifying the system that decoheres is actually a pseudo-problem, which vanishes as soon as one acknowledges the relative nature of decoherence. Second, the usually supposed link between decoherence and energy dissipation is misguided. As previously pointed out, energy dissipation and decoherence are different phenomena, and we shall argue for this difference on the basis of the relative nature of decoherence. (shrink)

The modal-Hamiltonian interpretation belongs to the modal family of interpretations of quantum mechanics. By endowing the Hamiltonian with the role of selecting the subset of the definite-valued observables of the system, it accounts for ideal and non-ideal measurements, and also supplies a criterion to distinguish between reliable and non-reliable measurements in the non-ideal case. It can be reformulated in an explicitly invariant form, in terms of the Casimir operators of the Galilean group, and the compatibility of the MHI with the (...) theory of decoherence has been proved. Nevertheless, perhaps its main advantage in the eyes of a scientist is given by its several applications to well-known physical situations, leading to results compatible with experimental evidence. The purpose of this paper is to add a new application to the list: the case of optical isomerism, which is a central issue for the philosophy of physics and of chemistry since it points to the core of the problem of the relationship between physics and chemistry. Here it will be shown that the MHI supplies a direct and physically natural solution to the problem, a solution that does not require putting classical assumptions in “by hand.”. (shrink)

The problem of the reduction of chemistry to physics has been traditionally addressed in terms of classical structural chemistry and standard quantum mechanics. In this work, we will study the problem from the perspective of the Quantum Theory of Atoms in Molecules, proposed by Richard Bader in the nineties. The purpose of this article is to unveil the role of QTAIM in the inter-theoretical relations between chemistry and physics. We argue that, although the QTAIM solves two relevant obstacles to reduction (...) by providing a rigorous definition of chemical bond and of atoms in a molecule, it appeals to concepts that are unacceptable in the quantum–mechanical context. Therefore, the QTAIM fails to provide the desired reduction. On the other hand, we will show that the QTAIM is more similar to Bohmian mechanics and that the basic elements of both theories are closely related. (shrink)

In a recent article entitled “The problem of molecular structure just is the measurement problem”, Alexander Franklin and Vanessa Seifert argue that insofar as the quantum measurement problem is solved, the problems of molecular structure are resolved as well. The purpose of the present article is to show that such a claim is too optimistic. Although the solution of the quantum measurement problem is relevant to how the problem of molecular structure is faced, such a solution is not sufficient to (...) account for the structure of molecules as understood in the field of chemistry.

The purpose of this text is to tell the story of the implementation of the _Act Respecting End-of-Life Care,_ referred to hereafter as _Law 2_ (Gouvernement du Québec, 2014) with an emphasis on the ambiguous role of ethics in the Interdisciplinary Support Groups (ISGs), created by Quebec's _Ministère de la santé et des services sociaux_ (MSSS). As established, ISGs provide “clinical, administrative and ethical support to health care professionals responding to a request for Medical aid in dying (MAiD)” (Gouvernement du (...) Québec, 2015). It is suggested that their composition includes the participation of a person with an expertise in ethics. These ISGs represent an important innovation for stakeholders involved in MAiD. To date, no scientific research has specifically addressed ISGs and little research has been conducted in other jurisdictions on the roles, operations and practices of MAiD support structures, especially the implication of ethics. Several ISGs have certainly developed promising practices that could benefit all stakeholders in the wider field of ethics and end of life. We will explore the development of ISGs in Quebec as a support structure for MAiD by highlighting the role that ethics has played (and should play) in these morally and humanly challenging situations.

The interpretation of the concept of reduced state is a subtle issue that has relevant consequences when the task is the interpretation of quantum mechanics itself. The aim of this paper is to argue that reduced states are not the quantum states of subsystems in the same sense as quantum states are states of the whole composite system. After clearly stating the problem, our argument is developed in three stages. First, we consider the phenomenon of environment-induced decoherence as an example (...) of the case in which the subsystems interact with each other; we show that decoherence does not solve the measurement problem precisely because the reduced state of the measuring apparatus is not its quantum state. Second, the non-interacting case is illustrated in the context of no-collapse interpretations, in which we show that certain well-known experimental results cannot be accounted for due to the fact that the reduced states of the measured system and the measuring apparatus are conceived as their quantum states. Finally, we prove that reduced states are a kind of coarse-grained states, and for this reason they cancel the correlations of the subsystem with other subsystems with which it interacts or is entangled.

Despite becoming one of the most active research areas in organizational behavior, the field of organizational justice has stayed at a safe distance from moral questions of values, as well as from critical questions regarding the implications of fairness considerations on the status quo of power relations in today’s organizations. We argue that both organizational justice research and the managerial practices it informs lack reflexivity. This manifests itself in two possible hypocrisies of fairness. Managers may apply organizational justice knowledge but (...) fail to increase the actual levels of fairness in employment relations. Researchers, on the other hand, may claim to promote fairness through their work while actually providing managers with tools that enable or even encourage them to feed the hypocrisy of fairness identified above. As␣part of our argument, we identify three types of mechanisms managers may use to influence and manage the formation of fairness perceptions. We consider how the exercise of power is related to the potential application of organizational justice knowledge across individual, interpersonal and social levels. Our approach makes power dynamics and moral implications salient, and questions the purely subjectivist view of justice researchers that deliberately discards normative aspects. The questions opened up by considering alternative mechanisms for creating fairness perceptions have led us to formulate a research agenda for organizational justice research that takes multiple stakeholder interests, power dynamics and ethical implications into account. We believe that the fields of organizational justice and normative justice can benefit from combined research. (shrink)

Managers tasked with organizational change often face irreconcilable demands on how to enact justice—situations we call _justice conundrums_. Drawing on interviews held with managers before and after a planned large-scale change, we identify specific conundrums and illustrate how managers grapple with these through three prototypical paths. Among our participants, the paths increasingly diverged over time, culminating in distinct career decisions. Based on our findings, we develop an integrative process model that illustrates how managers grapple with justice conundrums. Our contributions are (...) threefold. First, we elucidate three types of justice conundrums that managers may encounter when enacting justice in the context of planned organizational change (the justice intention-action gap, competing justice expectations, and the justice of care vs. managerial-strategic justice) and show how managers handle them differently. Second, drawing on the motivated cognition and moral disengagement literature, we illustrate how cognitive mechanisms coalesce to allow managers to soothe their moral (self-) concerns when grappling with these conundrums. Third, we show how motivated justice intentions ensuing from specific justice motives, moral emotions, and circles of moral regard predict the types of justice conundrums managers face and the paths they take to grapple with them.

Two recent papers appeared in FOOP disagree regarding the role played by decoherence in quantum physics. On the one hand, Elise Crull considers that decoherence, by itself, solves many conceptual problems in quantum physics, with no need of interpretative considerations. On the other hand, Antonio Vassallo and Michael Esfeld reply by correctly claiming that, although decoherence is a powerful tool to deal with conceptual problems, it does not dispense us from interpreting the formalism. In this brief note we want to (...) contribute to the debate with further considerations from another viewpoint. In this work we show that the discussions "decoherence versus interpretation" revolve around whether the theory of decoherence requires interpretive considerations to solve the measurement problem. In general, those discussions take the theory of decoherence for granted, as if it would not involve any difficulty. Therefore, they commonly focus on the "interpretation" wing: even in the case that the open system decoheres in a given basis, the whole closed system is still in a superposition and, thus, without an adequate interpretation, it cannot be said that the observables defined by that basis behave classically. Here we have focused on the "decoherence" wing: given the conceptual challenges that the theory must face and the alternative approaches to the orthodox view, the understanding of the very phenomenon of decoherence still requires a great deal of interpretive work.

The aim of the present paper is to supply an elucidation of the concept of information in the communicational context. For this purpose, two traditional interpretations of the concept of information, the epistemic and the physical interpretations, will be distinguished, and their specific problems will be considered. In particular, whereas the epistemic interpretation misses an essential feature of communication, the physical interpretation faces difficulties in the quantum domain. The final goal will be to argue that the difficulties of the physical (...) interpretation can be overcome by means of a manipulability conception of causation. (shrink)

Combining physics and philosophy, this is a uniquely interdisciplinary examination of quantum information science. Suitable as both a discussion of the conceptual and philosophical problems of this field and a comprehensive stand-alone introduction, this book will benefit both experienced and new researchers in quantum information and the philosophy of physics.

This article reflects on context effects in the study of behavioral ethics and organizational justice. After a general overview, we review three key challenges confronting research in these two domains. First, we consider social scientific versus normative approaches to inquiry. The former aims for a scientific description, while the latter aims to provide prescriptive advice for moral conduct. We argue that the social scientific view can be enriched by considering normative paradigms. The next challenge we consider, involves the duality of (...) morally upright versus morally inappropriate behavior. We observe that there is a long tradition of categorizing behavior dichotomously rather than continuously. We conclude by observing that more research is needed to compare the dichotomous versus continuous perspectives. Third, we examine the role of “cold” cognitions and “hot” affect in making judgments of ethicality. Historically speaking, research has empathized cognition, though recent work has begun to add greater balance to affective reactions. We argue that both cognition and affect are important, but more research is needed to determine how they work together. After considering these three challenges, we then turn to our special issue, providing short reviews of each contribution and how they help in better addressing the three challenges we have identified.
