In a communication network with a source node, a multicast tree is defined as a tree rooted at the source node and all its leaves being recipients of the multicast originating at the source. The tree or bandwidth cost is normally measured by its utilization of tree links along with the quality of service measures such as delay constraint and end-to-end delay. However, if nodes are allowed to join or leave the multicast group at any time during the lifetime of (...) the multicast connection, then the problem is known as dynamic multicast routing problem. In this article, we combine a greedy approach with static multicast routing using Tabu Search to find a low-cost dynamic multicast tree with desirable QoS parameters. The proposed algorithm is then compared with several static multicast routing algorithms. The simulation results show that, on a large number of events, i.e., where nodes are leaving or joining, the proposed algorithm is able to find multicast trees of lower cost and more desirable QoS properties.

In the late eighteenth century, an array of European political thinkers attacked the very foundations of imperialism, arguing passionately that empire-building was not only unworkable, costly, and dangerous, but manifestly unjust. Enlightenment against Empire is the first book devoted to the anti-imperialist political philosophies of an age often regarded as affirming imperial ambitions. Sankar Muthu argues that thinkers such as Denis Diderot, Immanuel Kant, and Johann Gottfried Herder developed an understanding of humans as inherently cultural agents and therefore necessarily (...) diverse. These thinkers rejected the conception of a culture-free "natural man." They held that moral judgments of superiority or inferiority could be made neither about entire peoples nor about many distinctive cultural institutions and practices.Muthu shows how such arguments enabled the era's anti-imperialists to defend the freedom of non-European peoples to order their own societies. In contrast to those who praise "the Enlightenment" as the triumph of a universal morality and critics who view it as an imperializing ideology that denigrated cultural pluralism, Muthu argues instead that eighteenth-century political thought included multiple Enlightenments. He reveals a distinctive and underappreciated strand of Enlightenment thinking that interweaves commitments to universal moral principles and incommensurable ways of life, and that links the concept of a shared human nature with the idea that humans are fundamentally diverse. Such an intellectual temperament, Muthu contends, can broaden our own perspectives about international justice and the relationship between human unity and diversity. (shrink)

Recent experiments have been used to “edit” genomes of various plant, animal and other species, including humans, with unprecedented precision. Furthermore, editing the Cas9 endonuclease gene with a gene encoding the desired guide RNA into an organism, adjacent to an altered gene, could create a “gene drive” that could spread a trait through an entire population of organisms. These experiments represent advances along a spectrum of technological abilities that genetic engineers have been working on since the advent of recombinant DNA (...) techniques. The scientific and bioethics communities have built substantial literatures about the ethical and policy implications of genetic engineering, especially in the age of bioterrorism. However, recent CRISPr/Cas experiments have triggered a rehashing of previous policy discussions, suggesting that the scientific community requires guidance on how to think about social responsibility. We propose a framework to enable analysis of social responsibility, using two example.. (shrink)

The focus of our research has been the definitions of pleasure in Ibn Sīnā’s philosophy. For that purpose we worked on identifying the principles upon which this issue has been built. In this context we made a comparison between intellectual pleasure and sensual pleasure. We came to the conclusion that the former is better than the latter. This in turn helped us make the distinction between the pleasure that occurs to us before the soul’s separation from the body and the (...) other which is after the separation. Hence we were able to recognize that man cannot obtain real happiness in this world, tarnished with vice, or only a little. That little happiness is absolutely incomparable with real happiness which occurs only after the separation of the soul from the body. (shrink)

Appeals to scrutinize the use of race and ethnicity as variables in genetics research notwithstanding, these variables continue to be inadequately explained and inconsistently used in research publications. In previous research, we found that published genetic research fails to follow suggestions offered for addressing this problem, such as explaining the basis on which these labels are assigned to populations. This study, an analysis of genetic research articles using race or ethnicity terms, explores possible features of journals that are associated with (...) improved reporting of race and ethnicity in genetic research. A journal’s expressed commitment to improving how race and ethnicity are used in genetic research, demonstrated by an editorial or in its instructions to authors, was the strongest predictor of following recommendations about reporting race and ethnicity. Journal impact factor had only a limited positive effect on attention to these issues, suggesting that editorial resources associated with higher impact factor journals are not sufficient to improve practices. Our findings reiterate that race and ethnicity variables are used inconsistently in genetic research, but also shed light on how journals might improve practices by highlighting the need for scientists to carefully scrutinize the use of these variables in their work.

Robust technology infrastructure is needed to enable learning health care systems to improve quality, access, and cost. Such infrastructure relies on the trust and confidence of individuals to share their health data for healthcare and research. Few studies have addressed consumers’ views on electronic data sharing and fewer still have explored the dual purposes of healthcare and research together. The objective of the study is to explore factors that affect consumers’ willingness to share electronic health information for healthcare and research. (...) This study involved a random-digit dial telephone survey of 800 adult Californians conducted in English and Spanish. Logistic regression was performed using backward selection to test for significant associations of each explanatory variable with the outcome variable. The odds of consent for electronic data sharing for healthcare decreased as Likert scale ratings for EHR impact on privacy worsened, odds ratio = 0.74, 95% CI [0.60, 0.90]; security, OR = 0.80, 95% CI [0.66, 0.98]; and quality, OR = 0.59, 95% CI [0.46–0.75]. The odds of consent for sharing for research was greater for those who think EHR will improve research quality, OR = 11.26, 95% CI [4.13, 30.73]; those who value research benefit over privacy OR = 2.72, 95% CI [1.55, 4.78]; and those who value control over research benefit OR = 0.49, 95% CI [0.26, 0.94]. Consumers’ choices about electronically sharing health information are affected by their attitudes toward EHRs as well as beliefs about research benefit and individual control. Design of person-centered interventions utilizing electronically collected health information, and policies regarding data sharing should address these values of importance to people. Understanding of these perspectives is critical for leveraging health data to support learning health care systems. (shrink)

The US National Institute of Health’s Human Microbiome Project aims to use genomic techniques to understand the microbial communities that live on the human body. The emergent field of microbiome science brought together diverse disciplinary perspectives and technologies, thus facilitating the negotiation of differing values. Here, we describe how values are conceptualized and negotiated within microbiome research. Analyzing discussions from a series of interdisciplinary workshops conducted with microbiome researchers, we argue that negotiations of epistemic, social, and institutional values were inextricable (...) from the reflective and strategic category work that defined and organized the microbiome as an object of study and a potential future site of biomedical intervention. Negotiating the divergence or tension between emerging scientific and regulatory classifications also activated “values levers” and opened up reflective discussions of how classifications embody values and how these values might differ across domains. These data suggest that scholars at the intersections of science and technology studies, ethics, and policy could leverage such openings to identify and intervene in the ways that ethical/regulatory and scientific/technical practices are coproduced within unfolding research.

This paper examines the effects of employees’ sense that they work for a purpose-driven company on their workplace sustainability behaviors. Conceptualizing corporate purpose as an overarching, relevant, shared ethical vision of why a company exists and where it needs to go, we argue that it is particularly suited for driving employee sustainability behaviors, which are more ethically complex than the types of employee ethical behaviors typically examined by prior research. Through four studies, two involving the actual employees of construction companies, (...) we demonstrate that purpose drives the sustainability behaviors of employees by causing them to take psychological ownership of sustainability. In addition, we show that the sustainability-enhancing effect of purpose is stronger when employees perceive that they have higher autonomy in enacting their sustainability actions and for those employees for whom being moral is more central to their sense of self.

This collection of original essays by leading historians of political thought examines modern European thinkers' writings about conquest, colonization and empire. The creation of vast transcontinental empires and imperial trading networks played a key role in the development of modern European political thought. The rise of modern empires raised fundamental questions about virtually the entire contested set of concepts that lay at the heart of modern political philosophy, such as property, sovereignty, international justice, war, trade, rights, transnational duties, civilization and (...) progress. From Renaissance republican writings about conquest and liberty to sixteenth-century writings about the Spanish conquest of the Americas through Enlightenment perspectives about conquest and global commerce and nineteenth-century writings about imperial activities both within and outside of Europe, these essays survey the central moral and political questions occasioned by the development of overseas empires and European encounters with the non-European world among theologians, historians, philosophers, diplomats and merchants.

The interpretive strategy of this article is to identify the joint stock company as an independent unit of analysis in Adam Smith's theory of international political economy. Such companies, in Smith's view, had corrupted and captured many European and non-European governments and undermined their societies' ability to engage in peaceful transnational affairs and equitable self-rule. In contrast with Smith's well-known concerns about the rise of commerce in modern Europe in his four-stage account of social development-- which were outweighed, in his (...) view, by the many material benefits and personal liberties brought about by the eclipse of feudalism--his narrative of globalization offers a trenchantly critical appraisal of commercial practices that ultimately undermine many of the gains that the initial rise of modern commerce once made possible. Even in his rare moments of optimism about the future of global relations, Smith remained deeply ambivalent about globalization. (shrink)

Dans le cadre des algorithmes numériques introduits et élaborés par les mathématiciens arabes, à partir du ixe siècle, figure l'algorithme de l'extraction de la racine carrée d'un entier naturel. Cet algorithme a été étudié chez plusieurs d'entre eux et surtout bien expliqué par alBaġdādī dans le chapitre « Comment extraire la racine des nombres entiers » de son livre « La complétion du calcul », Al-takmila fī al-ḥisāb 1. Dans ce chapitre, al-Baġdādī expose son travail pédagogiquement en six sections traitant (...) de plusieurs manières différentes le problème de l'extraction de la racine carrée d'un entier 2. À la même époque, dans un texte isolé intitulé « Sur la cause de la racine, de son doublement et de son déplacement 3 », Ibn al-Hayṯam donne une justification géométrique de l'algorithme en se basant sur des notions algébriques précises.

We study the different solution strategy for solving epidemic model in different imprecise environment, that is, a Susceptible-Infected-Susceptible model in imprecise environment. The imprecise parameter is also taken as fuzzy and interval environment. Three different solution procedures for solving governing fuzzy differential equation, that is, fuzzy differential inclusion method, extension principle method, and fuzzy derivative approaches, are considered. The interval differential equation is also solved. The numerical results are discussed for all approaches in different imprecise environment.

In this research, we evaluate the response of Brazilian consumers to corporate social responsibility (CSR) initiatives accompanied by a price increase. We demonstrate that the extent to which Brazilian consumers perceive a company to be socially responsible (i.e., their CSR perceptions) is related to both the basic transactional outcome of purchase intentions as well as two relational outcomes: the likelihood to switch to a competitor and to complain about the CSR-based price increase. More interestingly, we find that these relationships are (...) jointly mediated by the consumers' perceptions of price fairness and feelings of personal satisfaction. Perhaps most interesting, we find that these mediating effects vary with consumer purchasing power; the mediating effect of price fairness on purchase intention is stronger for lower income than for higher income consumers, whereas the mediating effects of personal satisfaction on switching and complaining intentions are stronger for higher income than for lower income consumers.

The Iraqi constitution of 2005 grants freedom of religious thought, belief and practice for all religions. This study was also based on the premise that the constitutional rights are not adhered to in Iraq, even by government officials, which could be due to the absence of suitable legislations subsequent to the framing of the constitutional provisions. An analytical and descriptive research design was adopted for this study. Data was collected from primary and secondary sources through documentation research and evaluation of (...) historical sources. The primary data comprised Articles of the Iraqi constitution, and a few national and international legal instruments related to religious freedom. Secondary data included empirical research studies, books, articles and other published sources. This study therefore took the form of an empirical legal research as it involved the issues of constitutional reforms in the field of religious freedom. A comparative approach was adopted in analyzing the documents about religion and politics related to both the Arab region and the West. The focus was on the measures that should be adopted to advance the dialogues of religious freedom and maintain religious neutrality in all government policies. The study found out that there were apparent contradictions between the constitutional provisions and the State Laws. Similarly, the Iraqi civil and penal codes remain silent regarding legal remedies for the violation of constitutional provisions. (shrink)

Physicians and other health care providers owe ethical and legal duties to patients to maintain the secrecy of the information learned during the course of patient care. This obligation is fulfilled by limiting access to such information to only those involved in the patient's care-that is, to those within the “circle of confidentiality.” As a general rule, providers may only disclose to others with the written prior consent of the patient. Exceptions may be “ethically and legally justified because of overriding (...) social considerations,” when permitted or compelled by law. For example, eleven states permit providers to disclose identified records to approved researchers.’ Many states compel disclosure in cases where a patient threatens serious bodily harm to another; require reporting to health or law enforcement authorities of communicable diseases, gunshot or knife wounds, or child abuse; and mandate reporting of cancer or other health care cases to state registries.

This research investigates the interplay between leadership styles and institutional corporate social responsibility (CSR) practices. A large-scale field survey of managers reveals that firms with greater transformational leadership are more likely to engage in institutional CSR practices, whereas transactional leadership is not associated with such practices. Furthermore, stakeholder-oriented marketing reinforces the positive link between transformational leadership and institutional CSR practices. Finally, transactional leadership enhances, whereas transformational leadership diminishes, the positive relationship between institutional CSR practices and organizational outcomes. This research highlights (...) the differential roles that transformational and transactional leadership styles play for a firm’s institutional CSR practices and has significant implications for theory and practice.

Corporate social responsibility (CSR) continues to gain attention atop the corporate agenda and is by now an important component of the dialogue between companies and their stakeholders. Nevertheless, there is still little guidance as to how companies can implement CSR activity in order to maximize returns to CSR investment. Theorists have identified many company-favoring outcomes of CSR; yet there is a dearth of research on the psychological mechanisms that drive stakeholder responses to CSR activity. Borrowing from the literatures on meansend (...) chains and relationship marketing, we propose a conceptual model that explains how CSR provides individual stakeholders with numerous benefits (functional, psychosocial, and values) and how the type and extent to which a stakeholder derives these benefits from CSR initiatives influences the quality of the relationship between the stakeholder and the company. The paper discusses the implications of these insights and highlights a number of areas for future research. (shrink)

This paper examines how employees react to their organizations’ corporate social responsibility initiatives. Drawing upon research in internal marketing and psychological contract theories, we argue that employees have multi-faceted job needs and that CSR programs comprise an important means to fulfill developmental and ideological job needs. Based on cluster analysis, we identify three heterogeneous employee segments, Idealists, Enthusiasts, and Indifferents, who vary in their multi-faceted job needs and, consequently, their demand for organizational CSR. We further find that an organization’s CSR (...) programs generate favorable employee-related outcomes, such as job satisfaction and reduction in turnover intention, by fulfilling employees’ ideological and developmental job needs. Finally, we find that CSR proximity strengthens the positive impact of CSR on employee-related outcomes. This research reveals significant employee heterogeneity in their demand for organizational CSR and sheds new light on the underlying mechanisms linking CSR to employee-related outcomes. (shrink)

The ontological model framework for an operational theory has generated much interest in recent years. The debate concerning reality of quantum states has been made more precise in this framework. With the introduction of generalized notion of contextuality in this framework, it has been shown that completely mixed state of a qubit is preparation contextual. Interestingly, this new idea of preparation contextuality has been used to demonstrate nonlocality of some \(\psi \) -epistemic models without any use of Bell’s inequality. In (...) particular, nonlocality of a non maximally \(\psi \) -epistemic model has been demonstrated from preparation contextuality of a maximally mixed qubit and Schrödinger’s steerability of the maximally entangled state of two qubits (Leifer and Maroney, Phys Rev Lett 110:120401, 2013). In this paper, we, show that any mixed state is preparation contextual. We, then, show that nonlocality of any bipartite pure entangled state, with Schmidt rank two, follows from preparation contextuality and steerability provided we impose certain condition on the epistemicity of the underlying ontological model. More interestingly, if the pure entangled state is of Schmidt rank greater than two, its nonlocality follows without any further condition on the epistemicity. Thus our result establishes a stronger connection between nonlocality and preparation contextuality by revealing nonlocality of any bipartite pure entangled states without any use of Bell-type inequality.

It is unclear whether the regulatory distinction between non-identifiable and identifiable information—information used to determine informed consent practices for the use of clinically derived samples for genetic research—is meaningful to patients. The objective of this study was to examine patients' attitudes and preferences regarding use of anonymous and identifiable clinical samples for genetic research. Telephone interviews were conducted with 1,193 patients recruited from general medicine, thoracic surgery, or medical oncology clinics at five United States academic medical centers. Wanting to know (...) about research being done was important to 72% of patients when samples would be anonymous and to 81% of patients when samples would be identifiable. Only 17% wanted to know about the identifiable scenario but not the anonymous scenario. Curiosity-based reasons were the most common among patients who wanted to know about anonymous samples. Of patients wanting to know about either scenario, approximately 57% would require researchers to seek permission, whereas 43% would be satisfied with notification only. Patients were more likely to support permission in the anonymous scenario if they had more education, were Black, less religious, in better health, more private, and less trusting of researchers. The sample, although not representative of the general population, does represent patients at academic medical centers whose clinical samples may be used for genetic research. Few patients expressed preferences consistent with the regulatory distinction between non-identifiable and identifiable information. Data from this study should cause policy-makers to question whether this distinction is useful in relation to research with previously collected clinically derived samples. (shrink)
