Importance Sampling for a Markov Modulated Queuing Network with Customer Impatience until the End of Service
Get PDFFor more than two decades, there has been a growing of interest in fast simulation techniques for estimating probabilities of rare events in queuing networks. Importance sampling is a variance reduction method for simulating rare events. The present paper carries out strict deadlines to the paper by Dupuis et al for a two node tandem network with feedback whose arrival and service rates are modulated by an exogenous finite state Markov process. We derive a closed form solution for the probability of missing deadlines. Then we have employed the results to an importance sampling technique to estimate the probability of total population overflow which is a rare event. We have also shown that the probability of this rare event may be affected by various deadline values.Importance Sampling, Queuing Network, Rare Event, Markov Process, Deadline
Did the LUA Directive increase competition and decrease prices in the market for non-prescription pharmaceuticals?
No full textLUA Directive was introduced for first time in Norway in 2003 to provide better availability and lower prices for non-prescription pharmaceuticals. The main idea behind implementing such a directive was to increase the competition in the non-pharmaceutical market by letting other retail outlets than the pharmacies to provide non-prescription pharmaceuticals. Based on results from a price investigation by The Norwegian Medicines Agency in 2010, LUA Directive was not very successful to slow down the prices but instead the Directive led to market segmentation and product differentiation
Divine Architecture: Non-Algorithmic World-Selection and Rahmani Branch-Optimization in Strong Occasionalism
No full textThe Leibnizian best-possible-world theodicy subjects divine sovereignty to an external axiological calculus, generating an intractable architectonic problem. Contemporary rivals (libertarian agent-causation, Thomistic concurrentism, Molinism) attempt escape via metaphysical "hatches" that, upon analysis, collapse into hidden occasionalism or incoherence. This paper argues that a coherent theology of divine sovereignty and love requires embracing strong occasionalism as its foundation. Building on two companion papers—which establish the incommensurability of world-types via Category Theory and resolve the occasionalist "author of sin" paradox via Formal Agency—we construct the Two-Tier Sovereign Model. In Tier 1, God makes a non-algorithmic, sovereign selection among incommensurable world-types (e.g., C_W1: Redemptive Struggle). In Tier 2, within the chosen type, God instantiates the Rahmani-Optimal Branch via a Threefold Filter that optimizes for essential consistency, maximal formal agency, and contextual divine mercy (rahmah). This model synthesizes absolute divine causality with meaningful creaturely responsibility, reframes the problem of evil as a question of sovereign expressive choice and rahmani-optimal context-setting, and yields the Rahmani-Optimality Thesis: our world is the optimally merciful instantiation of a sovereignly chosen kind of goodness. The result is a robust, non-consequentialist theological architecture that affirms God as both perfectly sovereign and perfectly good
Telle Antigone, relever le père harki. Le récit comme sépulture dans Moze de Zahia Rahmani
Get PDFMoze, le premier récit de l’auteure française d’origine algérienne Zahia Rahmani, explore une figure paternelle ambiguë, celle du père harki. Anciens supplétifs de l’armée française, certains harkis sont rapatriés après l’indépendance de l’Algérie dans une France qui refuse de les reconnaître comme citoyens à part entière. Le père harki apparaît dans le récit de Rahmani comme un homme honteux, dont la condition même de père est empêchée par sa honte. Dans cet article, nous analysons le rapport de la narratrice à son père harki à la lumière de la figure d’Antigone. À l’instar de l’héroïne de la tragédie de Sophocle, la narratrice de Moze cherche à relever le père mort, à le ramener du côté de l’humanité et s’emploie à faire pour lui oeuvre de sépulture.In Zahia Rahmani’s first novel Moze, the French author born in Algeria, explores an ambiguous paternal figure: the harki father. Harkis were Muslim Algerian loyalists who served as Auxiliaries in the French Army during the Algerian War. After the independence of Algeria some of them were repatriated in France where they were not considered as full citizens, and, even worse, as fully human. In Rhamani’s novel, the harki father is a shameful man whose fatherhood is impeded by his shame. In this article, we use Antigone’s framework to examine the relationship between the narrator and her harki father. Like the heroine of Sophocle’s tragedy, the narrator of Moze wants to raise a (symbolic) mound for her dead father as a way of assessing his humanity. To do so, the narrator performs “une oeuvre de sépulture,” a kind of burial with words
Ett känslosamt möte : Socialsekreterares känslor och känslohantering kring barn som utsatts för sexuella övergrepp.
No full textTitle: An emotional meeting - The feelings and emotional management of social workers who meet sexually abused children. Education: Social work study program, 210 credits Author: Selma Rahmani och Frida Löhnert Supervisor: Erika Lundby Assessor: Jan Petersson The aim of this study was to investigate the feelings and emotional management of social workers who work, or have been working with sexually abused children. The study was conducted using a qualitative approach through semi-structured interviews with social workers. The social workers that participated in this study have thus had the experience of meeting children who have been sexually abused, and have been working with investigation or in treatment purposes. The selection was based on gaining understanding for the feelings that occur amongst the social workers and the strategies that they use to manage these feelings. The interviews were complemented with previous research in the form of scientific articles and theses. In relation to our theoretical approaches, we could deduce some important conclusions. We were for example able to confirm previous researches regarding the fact that working with sexually abused children is mentally stressful, and that it might be difficult to harbor these feelings. The results also showed that different strategies can be useful to harbor the feelings that arise. Through our analysis, this has been problematized and we have discovered that some of the strategies, especially the ones that are spontaneous or self-chosen, may lead to negative consequences.

Get PDFTrigger Point Theory as Aesthetic Activism: A Transdisciplinary Approach to Environmental Restoration Aviva A. Rahmani This dissertation presents a new approach to addressing environmental degradation based on transdisciplinary ecological art. Transdisciplinarity is defined here as merging art and science to discover new insights. Ecological art is defined as an aesthetic practice that promotes environmental resilience. This writing will describe why those approaches are essential to restoring resilient bioregionalism. It introduces the author’s own heuristic perspectives and methodologies and demonstrates how they may be integrated with technology and science. The problems of accelerated loss of coastal (littoral) zone biodiversity, degraded water quality, and habitat fragmentation need critical attention. The author’s research goal was to present a replicable set of guidelines for identifying small points of restoration for wetland littoral zones (the coastal region between terrestrial and marine life) based on a case study called Ghost Nets, scaled to a second case study, Fish Story. Her novel approach included establishing relevant parallels from quantum physics and acupuncture to energetic systems. Additional specific analogies were explored from visual arts, theatre, music, dance, and performance art, to discover a holistic and integrated point of view. Parallels and analogies were drawn by interrogating the two case studies. An important aim of the study was to examine how certain restoration practices could be scaled up to the bioregional level and integrated with a special theory, Trigger Point Theory, to reinforce healthy ecosystems. This included an analysis of how restored upland ecotones and a different relationship to other species could contribute to restoration in the littoral zone. The analysis critiqued how anthropocentric considerations often fail to protect vulnerable water systems. The role of environmental justice for vulnerable human populations and ethical concerns for other animal species was included in that analysis. The author also claims that when artists work with Geographic Information Systems (GIS) mapping, that may propel a new transdiscourse and eventually make heuristic information scientifically useful. Insight from the Ghost Nets case study informed data collections and GIS mapping for the Southern Gulf of Maine. Those insights and the mapping were used to analyze relationships between finfish abundance, eelgrass, and invasive, predatory green crabs. Conclusions were drawn that are relevant to coastal and fisheries management practices. The author used performative approaches to contribute expert witnessing to her conclusions. Questionnaires were used to determine how much community awareness was accomplished with the case studies, and assess effects on future behavior. By combining art and science methodologies, the author revealed insights that could help small restored sites act as trigger points towards restoration of healthy bioregional systems more efficiently than would be possible through restoration science alone. In scaling up (applying small models to larger systems) and applying these practices for landscape ecology, the author assembled a set of recommendations for other researchers to implement these ideas in the future. Those recommendations included the formal engagement of ecological artists as equal partners on environmental restoration teams
مرعاۃ المفاتیح (شرح مشکاۃ المصابیح) میں مولانا عبیداللہ رحمانی مبارک پوری کے منہج کا اختصاصی مطالعہ: A Specialized Study of the Methodology of Maulana Ubaidullah Rahmani Mubarakpuri in the Commentary 'Mirat al-Mafatih' on Mishkat al-Masabih
No full textMishkat al-Masabih is a book of Hadith included in the curriculum of religious seminaries in the Indian subcontinent. In this region, three commentaries in Arabic have been written on this book. Among them is a renowned commentary by the distinguished scholar of the Ahl-e-Hadith school of thought, Maulana Obaidullah Rahmani, which is famously known as "Miratual -Mafātīḥ” This commentary holds a prominent position in explaining the text of the Hadith. It includes the introduction of narrators, resolution of conflicting hadith, and discussions on jurisprudential schools of thought. The most remarkable feature of this commentary is that the author does not represent any specific school of jurisprudence. Instead, He gives preference to opinions based on evidence. The author has adopted the methodology of the Muhaddithin (Hadith scholars) in matters of beliefs and ambiguous texts, specifically the approach of Tafweedh (consigning the meaning to Allah). One of the notable qualities of this commentary is that the Hadiths have been numbered, making it easier to benefit from the book and reference specific narrations efficiently. The commentary spans nine volumes and covers up to the end of Kitab al-Manasik (the Book of Pilgrimage)
