Publisher: name: Revista Turismo & Desenvolvimento
Year: 2010

description: O turismo cultural e religioso detém, hoje, um lugar importante na economia deste sector, sobretudo em cidades e locais onde a presença do património civil e religioso e as manifestações relacionadas com o domínio da crença e das práticas religiosas são relevantes. No contexto português, Braga é uma das cidades mais vocacionadas para o enraizamento e o desenvolvimento de actividades turísticas ligadas ao fenómeno cultural e religioso. Santiago de Compostela é um caso paradigmático, a imagem de cidade cultural por excelência, alicerçada no valor do seu património histórico, vinculado aos Caminhos de Santiago e ao culto religioso do Apóstolo com o auge nos anos do “Xacobeo”, fazem dela um caso único. Apoiados nos dados empíricos recolhidos através dos inquéritos por questionário, entrevistas e observação participante, discutimos a importância do turismo cultural e religioso nas cidades de Braga e Santiago de Compostela, tendo em conta as características territoriais da Euro-região (Norte de Portugal-Galiza). O nosso estudo pretende apresentar um produto conjunto de turismo cultural e religioso, entre as cidades de Braga e Santiago de Compostela.

description: We investigate the interplay of disorder and interactions in the accelerated transport of a Bose-Einstein condensate through an incommensurate optical lattice. We show that interactions can effectively cancel the damping of Bloch oscillations due to the disordered potential and we provide a simple model to qualitatively capture this screening effect. We find that the characteristic interaction energy, above which interactions and disorder cooperate to enhance, rather than reduce, the damping of Bloch oscillations, coincides with the average disorder depth. This is consistent with results of a mean-field simulation.

Weird Reading

Publisher: name: punctum books

description: It may seem strange to open an essay on the possi-bilities of Speculative Realist (SR) literary reading modes with a quotation from Derrida, whose sta-tus as one of the architects of the “linguistic turn” within the humanities supposedly makes him an enemy (or at least, an often convenient whipping post) of the new realists. Such is the odd flavor of this essay, which, situated outside of philosophy proper, seeks a more anti-disciplinary and even autistic relational field—that is to say, an amod-al, synaesthetic, fluid, and diffusely intentional model for discerning relations among thinkers and objects.2 Unlike Graham Harman (although very much influenced by him), who opened his essay “Vicarious Causation” by saying his theory of causation “is not some autistic moonbeam entering the window of an asylum,” but rather a “launching pad for a rigorous post-Heideggerian philosophy,”3I am hoping to follow just such moonbeams into many-chambered asylums. My thinking is hopefully rigorous, but also unreasonable.

description: Light emission is defined by its distribution in energy, momentum, and polarization. Here, we demonstrate a method that resolves these distributions by means of wide-angle energy-momentum spectroscopy. Specifically, we image the back focal plane of a microscope objective through a Wollaston prism to obtain polarized Fourier-space momentum distributions, and disperse these two-dimensional radiation patterns through an imaging spectrograph without an entrance slit. The resulting measurements represent a convolution of individual radiation patterns at adjacent wavelengths, which can be readily deconvolved using any well-defined basis for light emission. As an illustrative example, we use this technique with the multipole basis to quantify the intrinsic emission rates for electric and magnetic dipole transitions in europium-doped yttrium oxide (Eu$^{3+}$:Y$_{2}$O$_{3}$) and chromium-doped magnesium oxide (Cr$^{3+}$:MgO). Once extracted, these rates allow us to reconstruct the full, polarized, two-dimensional radiation patterns at each wavelength.

Realism And Representation: On the Ontological Turn
Creators: name: Sacilotto, Daniel
Publisher: name: punctum books
Year: 2013

description: The views associated with the title “speculative realism” are often coordinated with a so-called “ontological turn” that is said to have taken place in recent Continental philosophy.1 Yet it is rather unclear what exactly such a turn is supposed to entail. If, as Meillassoux argues, it is Kant’s name that sets the horizon for the anti-realist denouement that presumably characterizes both correlationism and idealism, then something like the overcoming of the critical turn in philosophy would seem to be centrally at stake.2 The turn towards ontology pro-posed by the new realists would then be the obverse of a turning away from Kantian epistemology and its implications. And, yet again, there are at least two historical vectors which we can intuitively link to an “ontological turn,” conceived as the overcoming of the critical paradigm.
O turismo na produção social do espaço rural contemporâneo: novas procuras e a emergência da nobilitação rural
Creators: name: Mendes, Luís
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2010

description: Ao longo das últimas décadas é visível um aumento da procura, consumo e frequência das áreas rurais portuguesas, essencialmente por populações urbanas ou não rurais. Tal aumento inscreve-se nas transformações das sociedades contemporâneas em geral, e das áreas rurais em particular, e resulta da consolidação de um modo de produção e apropriação do espaço rural como bem de consumo e como património comum. O espaço rural afirma-se como espaço de reserva de recursos e bens ambientais e também como espaço de memória e de herança cultural. O objectivo que preside a este breve ensaio é o de procurar compreender como a reinvenção e a idealização do passado rural revelam o princípio de patrimonialização através da redescoberta de novas funções (uma segunda vida trazida pela nobilitação rural). Este processo é sustentado por operações de invenção, encenação e simulação de uma singularidade local e de uma continuidade histórica inerentes aos espaços rurais, suportando, assim, a emergência de novas procuras residenciais.

"The World is an Egg": Realism, Mathematics, and the Thresholds of Difference

Publisher: name: punctum books
Year: 2013

description: To most people, the question or problem of realism—realism taken here to mean that there is a reality independent of our awareness or consciousness of this reality—is neither a question nor a problem; it is simply taken for granted. It is one of the unques-tioned assumptions of daily life. When I leave the house, there is no question my laptop remains where I left it and will be there upon my return; there is no question that there were many things in existence before my birth and that there will continue to be many things after my death; and finally, there is no question that there was a wealth of things in existence—stars, planets, dinosaurs, etc.—before the emergence of conscious, inquiring human beings. In our daily lives, therefore, to be a realist is a matter of common sense.1 When we begin to ask what it is that is real, however, or when we seek to determine whether our judgments regarding the nature of reality are correct or not, we begin to enter a quagmire of difficulties that have beset philosophers since the beginning of philosophy itself.

description: We consider the Standard Model extended by a hidden sector U(1)_X symmetry that is spontaneously broken at the TeV scale by the vacuum expectation value of an additional scalar field. We study "dark string" solutions in this model and their properties due to the Higgs portal and gauge kinetic mixing operators. We find that dark strings effectively interact with Higgs and Z bosons by linear couplings, and with leptons and baryons via Aharonov-Bohm couplings, thus possibly leading to new cosmological constraints on dark matter models with spontaneously broken extra U(1) symmetry factors.

description: In this survey we determine an explicit set of generators of the maximal ideals in the ring $\mathbb R[x_1,\dots,x_n]$ of polynomials in $n$ variables with real coefficients and give an easy analytic proof of the Bass-Vasershtein theorem on the Bass stable rank of $\mathbb R[x_1,\dots,x_n]$. The ingredients of the proof stem from different publications by Coquand, Lombardi, Estes and Ohm. We conclude with a calculation of the topological stable rank of $\mathbb R[x_1,\dots,x_n]$, which seems to be unknown so far.

Ontological Commitments
Creators: name: DeLanda, Manuel
Publisher: name: punctum books
Year: 2013

description: Any philosophy commits itself, explicitly or implicitly, to assert the existence of the entities that it intends to describe or explain. Philosophers who deny the truth of this statement—affirming for example that specifying what kinds of entities populate their world constrains their ability to think—usually assume an implicit ontology which is, for the same reason, uncritically accepted and poorly analyzed. Hence, declaring one’s ontological commitments from the start should be standard procedure in philosophy. Although ontologies vary widely, and it is unwise to try to fit them into a rigid taxonomy, for the purposes of this brief essay they can be classified into three categories: idealist, empiricist, and realist. For the idealist philosopher there are no entities that exist independently of the human mind; for the empiricist entities that can be directly observed can be said to be mind-independent, but everything else (electrons, viruses, causal capacities etc.) is a mere theoretical construct that is helpful in making sense of that which can be directly ob-served; for the realist, finally, there are many types of entities that exist autonomously even if they are not directly given to our senses.

description: Background: Metabolic syndrome (MetS) is rapidly increasing in prevalence with rising childhood obesity and sedentary lifestyles worldwide. The aim of this study was to estimate the prevalence of MetS and its components among Sudanese early adolescents in Khartoum State. Methods: A descriptive cross-sectional study was conducted at primary schools in Khartoum State. A questionnaire was administered to assess the sociodemographic characteristics of the participants. Anthropometric, blood pressure, and biochemical measurements were taken. Results: In total, 921 students, boys and girls aged 10–15 years old, participated in the study. The mean age of the participants was 12.59 ± 1.21 years. The overall prevalence rate of MetS was 2.3% using International Diabetes Federation (IDF) criteria. MetS was significantly more prevalent among boys than girls (3.4% vs. 1.5%). Obese adolescents had higher MetS prevalence than those who were overweight (14.9 vs. 2.8, p < 0.001). Conclusion: Boys had a significantly higher prevalence of metabolic syndrome than girls. Early adolescents from Sudan who are obese had more risk factors for MetS than those who are normal weight or overweight. It is important to address the causes of increased risk for MetS early in life to prevent the development of the disease in adult life.

title: Design and optimization of low-frequency piezoelectric MEMS energy harvesters based on machine learning
Creators: name: Ehsani Chimeh, Hamidreza
Publisher: name: Memorial University of Newfoundland
Year: 2024

description: Portable electronic applications are typically powered by batteries, which have limited lifespan and size constraints. Energy harvesting from parasitic vibrations using piezoelectricity is a demanding solution to improving the power supply efficiency of low-power portable devices and autonomous sensor networks. Vibrational energy harvesters with high operating frequency are not desirable considering the low-frequency characteristics of ambient vibrations (e.g., wind). The operation frequency range (known as bandwidth) is a key feature that should be improved under an unpredictable or uncontrollable condition of ambient vibrations. In this thesis, several piezoelectric MEMS energy harvesters have been developed to tackle these challenges. In order to facilitate the design process and determine the optimum physical dimensions, an artificial neural network is used to model the designs. In the first step, a sample dataset is created by numerical modeling to train a deep neural network. The validation results indicate that the trained DNN model can achieve around 90% estimation accuracy of device features, such as resonant frequency and harvested voltage. Next, this trained model is integrated with genetic algorithm as a performance estimator to optimize the geometry of the harvester to lower the resonant frequencies and improve the harvested voltage. With the intention of improving the accuracy of deep neural network, the transfer learning method is used for modeling another design. In this method, the DNN is firstly trained with a dataset created by the lump-parameter model; then, the trained network is transferred to a new deep model for another round of training with highly accurate FEM data samples to further reduce prediction error. It was shown that the new model can estimate the device features with more than 94% accuracy, which is 4% higher than the regular DNN. Finally, in the last design, our proposed AI-based methodology is utilized to estimate the mode shapes to enlarge the operational bandwidth specifically. The optimized energy harvesters have been fabricated through a standard micromachining process. Our measurement results confirm that the proposed AI-based methods can help reach the balanced summit of higher power density, lower resonant frequency, and larger bandwidth among the published works.

description: The associated Legendre functions $P_{l}^{(m)}(x)$ for a given $l-m$, may be taken into account as the increasing infinite sequences with respect to both indices $l$ and $m$. This allows us to construct the exponential generating functions for them in two different methods by using Rodrigues formula. As an application then we present a scheme to construct generalized coherent states corresponding to the spherical harmonics $Y_{m}^{m}(θ,ϕ)$.
Points of Forced Freedom: Eleven (More) Theses on Materialism
Creators: name: Johnston, Adrian
Publisher: name: punctum books
Year: 2013

description: Any materialism worthy of the name must involve elements of both naturalism and empiricism. However, it need not be straightforwardly and entirely naturalist or empiricist in the traditional (particularly pre-Kantian) senses of these labels (and, in the case of materialisms in the wake of German idealism, including transcendental mate-rialism, ought not to be). Following from this, any anti-naturalist rationalism, in whatever guise, can-not qualify as being simultaneously a materialism too. Although an anti-naturalist rationalism can be made consistent with (metaphysical) realism, this by no means renders it compatible with materialism strictly speaking. In still other words, there is no such thing as a purely formalist materialism; with reference to the birth of modern science, there is no Galileo without Bacon too. Both aversion to the experimental natural sciences of modernity as well as rejection of tying knowledge primarily to empirical routes of acquisition prompts thinking down paths leading to anachronistic Pythagorian-isms, ontological dualisms, spiritualist idealisms, religious mysticisms, and a unruly, proliferating swarm of confabulations, delusions, imaginings, fantasies, and ravings passing themselves off as rigorous, responsible philosophizing. Furthermore, insofar as an empirically informed, quasi-naturalist materialism is not in the least synonymous with and equivalent to rigid, mechanical determinism, an attuned materialist sensitivity to the natural sciences is not to be feared as the opening up to the immediate closing down of space for autonomous subjectivity and everything it brings with it.
title: Karl Stemolak (1875-1954) - ein Bildhauer mit großem sozialem Engagement für die Wiener Künstlerschaft
Creators: name: Stummer, Verena
Year: 2023

description: Diese Arbeit beschäftigt sich mit dem Leben und Werk des österreichischen Bildhauers Karl Stemolak (1875-1954). Neben seiner Tätigkeit als Bildhauer beeinflusste er die Wiener Kulturszene vor allem durch sein soziales Engagement. Bis auf wenige Werke im öffentlichen Raum ist heute jedoch kaum noch etwas von ihm bekannt. Ziel dieser Arbeit ist es zum einen, sein künstlerisches Werk im Kontext seiner Zeit einzuordnen. Grundlage für die Betrachtung des künstlerischen Œuvres ist ein dafür erstelltes Werkverzeichnis. Erst im Kontext mit den künstlerischen Normen des jeweilig herrschenden politischen Systems und im Vergleich mit Werken der Zeitgenoss:innen ist dabei eine sinnvolle Beurteilung seines Œuvres möglich. Zum Anderen widmet sich diese Arbeit in einem zweiten Abschnitt der Aufarbeitung der sozialen Tätigkeiten und den Leistungen des über Jahrzehnte in verschiedensten Künstlervereinigungen und Organisationen aktiven Künstlers. Oftmals ist die Beurteilung seiner Errungenschaften nur im Kontext der jeweiligen Vereinigung möglich, in der diese geleistet wurden. Generell spielt die politische und wirtschaftliche Entwicklung des Landes Österreich bei einer solchen Aufarbeitung eine wichtige Rolle, nur dadurch können bestimmte Ereignisse richtig eingeordnet und gewertet werden. Die österreichische Künstlerschaft unter der Herrschaft der Nationalsozialisten und Karl Stemolaks Handlungen unter dem Regime, fordern deshalb eine gesonderte Betrachtung. Trotz seines bereits hohen Alters zählte Karl Stemolak auch nach 1945 zu den Initiatoren des kulturellen und künstlerischen Wiederaufbaus. Eine Untersuchung seines Engagements für die sozialen und ökonomischen Verbesserungen der Künstlerschaft in der Nachkriegszeit bilden deshalb den Abschluss dieser Arbeit.

description: Na teoria dos “conjuntos complexos” (Giotart e Balfet, 2007), o Turismo é apresentado como conjunto, no qual os elementos interagem em sistema, segundo regras que permitem obter fenómenos globalmente previsíveis e identificáveis graças à dinâmica de agregação, entendidas como regras locais, visto que os agentes interagem com os agentes tecnicamente mais próximos. Neste artigo, discute-se se os métodos de modelização organizacional (Costa, 1996; Machado, 2009) de conjuntos complexos no Turismo baseados simultaneamente em estruturas hierárquicas, de autoridade, direcção e controlo e estruturas de contribuição e de mercado, com redes e organizações híbridas, podem ser aplicados, com pertinência, aos museus e cultura, entendidos enquanto envolvente turística na Lei das Políticas Públicas de Turismo (LPPT- art.º 10.º alínea e) do D.L. n.º 191/2009, publicado em 17.08.2009). Admitindo-se a autonomia e capacidade de auto-produção destas organizações, com relações que reduzam a complexidade e apropriabilidade com o ambiente envolvente permitindo recursos, analogias entre sistemas de poder, apura-se, também, por força de princípios de acção/reaçcão entre sistemas e através de metodologias aplicadas à observação do Direito se a cultura e os museus interagem com o Turismo, enquanto sistema de poder.

The role of volunteer tourism: the case of international work camps in Vojvodina, Serbia
Creators: name: Klicek, Tamara
name: Breda, Zélia
Publisher: name: Journal of Tourism & Development
Year: 2010

description: This paper addresses the importance ofvolunteer tourism as a strategy to contribute to tourism development in Serbia. The instability caused by the dissolution of Yugoslavia has prompted an economic crisis and a severe halt in tourism activities. International work camps in Serbia attract hundreds of volunteers from all over the world. This is considered to be helping to restore international tourism in the country and to subsequently building up and enhancing infrastructure. The paper presents an evolution of tourism in Serbia and briefly outlines the situation of tourism in Vojvodina, where numerous volunteer tourism activities have been carried out. Through the case study of international work camps promoted by the Volunteer Centre of Vojvodina (VCV), the paper addresses volunteers’ motivations and perceptions, and at the same time discusses how volunteering activities can contribute to tourism development. This case study reveals that most volunteer tourists see work camps also as a holiday experience, looking to visit tourist attractions in the area; simultaneously they are highly aware of their role in destination development. It also suggests that the high level of interaction between volunteers and locals raises community’s awareness to tourism potential, making the first step towards future tourism activities.

description: In this paper, we study homological dimensions of algebras linked by recollements of derived module categories, and establish a series of new upper bounds and relationships among their finitistic or global dimensions. This is closely related to a longstanding conjecture, the finitistic dimension conjecture, in representation theory and homological algebra. Further, we apply our results to a series of situations of particular interest: exact contexts, ring extensions, trivial extensions, pullbacks of rings, and algebras induced from Auslander-Reiten sequences. In particular, we not only extend and amplify Happel's reduction techniques for finitistic dimenson conjecture to more general contexts, but also generalise some recent results in the literature.

description: O presente trabalho estuda o ecoturismo. Buscou-se averiguar a existência de uma preocupação com a educação ambiental nas atividades e pacotes ‘ecoturísticos’ comercializados pelo mercado. Procurou-se conhecer o termo ecoturismo a partir das perspectivas da cultura de consumo e da sociedade do espetáculo e sob tal enfoque discutir suas relações com temas como turismo e consumo, natureza e educação ambiental; buscou-se também identificar as bases filosóficas do trabalho ecoturístico desenvolvido pelas operadoras de tais atividades; e por fim, realizar crítica conceitual acerca das relações entre os assuntos abordados por este estudo. Por tratar-se de pesquisa qualitativa, entrevistou-se 03 operadoras do mercado ecoturístico e 03 pesquisadores de áreas relacionadas aos temas propostos. O texto foi produzido a partir das informações obtidas por levantamento bibliográfico em diálogo com as opiniões obtidas nas entrevistas no trabalho de campo. Concluiu-se que o ecoturismo como atividade de mercado é pouco utilizado para a disseminação da consciência ambientalista por conta das operadoras terem uma visão da educação ambiental que a aproxima da educação formal e que tal característica não deve ser integrada às atividades turísticas – momentos de diversão e lazer; constatou-se também que o ecoturismo tem funcionado como mecanismo de produção de desejo consumista em seus participantes e reafirmado o tempo espetacular do capital.

title: Biochemical and genetic investigations for the production of β-lactam metabolites from Streptomyces clavuligerus ATCC27064 and Streptomyces pratensis ATCC33331
Creators: name: AbuSara, Nader Fareid

description: Streptomyces are recognized for their ability to produce a wide range of antimicrobial agents. In this thesis, two of the Streptomyces bacteria, Streptomyces clavuligerus and Streptomyces pratensis were the subject of my investigations. Streptomyces clavuligerus has the ability to produce a diverse set of β-lactams compounds; the β-lactamase inhibitor clavulanic acid (CA), the 5S clavams, and cephamycin C (Ceph-C). I first investigated the molecular features of two genes, cpe (orf12) and orf14, from the CA biosynthetic gene cluster (BGC) of S. clavuligerus and their roles in CA and 5S clavam biosynthesis. The two genes are essential for the production of CA since deletion of any of them abolishes CA biosynthesis. The two genes are thought to be involved in converting clavaminic acid into clavaldehyde during the late steps of CA biosynthesis. Different protein variants of CPE and ORF14 were prepared by site-directed mutagenesis and used to investigate their effects on CA and 5S clavam production. In addition, the regulatory impact of cpe on the transcription level of CA and 5S clavam biosynthetic genes was tested in cpe deleted and overexpressed mutants compared to the wild-type strain. Next, a comparative genomic study was conducted for CA and CA-like BGCs between the CA producer (S. clavuligerus) and non-producers (Streptomyces pratensis, Saccharomonospora. viridis, and Streptomyces sp. M41). One of the main differences is a large gene, nocE, resides within the CA-like BGCs of the non-producers species. Deletion and overexpression of nocE in S. clavuligerus were achieved, and their effects on physiology, general metabolism, and specialized metabolism were investigated. In the third part of the study, genomic analysis for BGCs was conducted for the S. pratensis ATCC33331 genome, which predicted 27 BGCs. None of the predicted products has been previously reported to be produced by this species. Therefore, I followed the one strain many compounds (OSMAC) approach to investigate the ability of S. pratensis to produce specialized metabolites. Our results revealed the production of a bioactive substance (SB) that has antimicrobial activity against Klebsiella pneumoniae. Biochemical and genetic procedures were performed to discover the identity of this substance.

title: Ultramontanismus und Infallibilität in der Wiener Kirchenzeitung im Vorfeld des Ersten Vaticanums (1860-1870)
Creators: name: Damberger, Florian
Year: 2022

description: Die ultramontane Weltsicht, die sich aus einer kirchlichen Freiheits- und Befreiungsbewegung heraus entwickelte, prägte das kirchliche Leben des deutschsprachigen Bereichs im 19. Jahrhundert wesentlich. Der Ultramontanismus wollte mehr und mehr die Kirche als societas perfecta gänzlich unabhängig denken und wurde dabei mit seinen Zielen im Verlauf des Jahrhunderts deutlich illusionär. Diese Diplomarbeit untersucht, wie sich der Ultramontanismus in der Berichterstattung eines konkreten Wochenblattes, der Wiener Kirchenzeitung, im Vorfeld des Ersten Vaticanums äußert und analysiert dabei, wie zentrale Ereignisse des Jahrzehnts vor dem Konzil in dieser radikal ultramontanen Zeitschrift, die allerdings nur lokale Bedeutung hatte, bewertet werden. Dabei wird besonders auf das Phänomen der Dogmatisierung der päpstlichen Unfehlbarkeit eingegangen, die in ein kritisches Verhältnis zum Ultramontanismus gesetzt wird. Die Wiener Kirchenzeitung erkannte das Phänomen der Infallibilität in seiner Bedeutung spät und vermochte keine klare Position dazu einzunehmen.

The ultramontanism supposed the church more and more as a societas perfecta, completely independent. Its aims became more and more illusionary during the century. This diploma thesis investigates how ultramontanism appears in the reporting of a concrete weekly magazine, the Wiener Kirchenzeitung (a radical ultramontane magazine), by focussing its way of reporting central events in the decade before the first Vatican council. The dogmatization of the pope’s infallibility is especially focused and related critically to ultramontanism. The Wiener Kirchenzeitung recognized the importance of the infallibility question late and was not able to take a clear position. This is because of its absence of theology, its polemic manner and its local focus which made a realistic and balanced reporting impossible.
A Pedagogy on the Verge of Disaster

description: The phrase that directs our reflections on this occasion leads me back to a text that has haunted all of my reflections on pedagogy and the university over the past fifteen years (and thus everything I wrote in The Claim of Language,1 to which I would like to return briefly  in  these  pages).  I  refer  to  a  brief  essay  by  Jean-François  Lyotard  that  was  first  published in Critique in 1978 under the title, “Endurance and the Profession.”2 It is an enigmatic  text  if  only  for  the  fact  that  what  is  named  “endurance”  goes  entirely  unde-fined in what is, on its face, a rather dark and despairing reflection – almost as though “endurance” stands in lieu of that for which it might serve, but which cannot be named, some hope, for example. I remain astonished and intrigued by this essay, but I believe I may now understand something of why it has so haunted me, so I would like to take my orientation from it. Whether or not I am correct in my intuitions, I can at least offer it as an exceptionally intriguing example of what we might want to consider as a “pedagogy of disaster” – or at least an example of what might be a step toward such a thing.

description: This paper presents an implementation of the Imperialist Competitive Algorithm (ICA) for solving the fuzzy random portfolio selection problem where the asset returns are represented by fuzzy random variables. Portfolio Optimization is an important research field in modern finance. By using the necessity-based model, fuzzy random variables reformulate to the linear programming and ICA will be designed to find the optimum solution. To show the efficiency of the proposed method, a numerical example illustrates the whole idea on implementation of ICA for fuzzy random portfolio selection problem.

description: We study the S=1/2 Heisenberg antiferromagnet on the Cairo pentagon lattice by the numerical-diagonalization method. We tune the ratio of two antiferromagnetic interactions coming from two kinds of inequivalent sites in this lattice, examining the magnetization process of the antiferromagnet; particular attention is given to one-third of the height of the saturation. We find that quantum phase transition occurs at a specific ratio and that a magnetization plateau appears in the vicinity of the transition. The plateau is accompanied by a magnetization jump on one side among the edges due to the spin-flop phenomenon. Which side the jump appears depends on the ratio.

Welcoming the Stranger: From Social Inclusion to Exilic Education
Creators: name: Doron, Edith
Publisher: name: punctum books
Year: 2013

description: I open with this poem on the arrival of the stranger and the question of community be-cause it speaks to the difference between the gesture of social inclusion legitimated by Kantian cosmopolitan ideals and translated into multicultural education in museums on  one  side,  and  the  gesture  of  welcoming  the  stranger  on  the  other.  It  speaks  to  the  difference between reception of the other as an interested act, as part of the struggle for recognition for the sake of being-at-home and therefore as an act that constitutes one’s sovereign ipseity on one side, and the encounter with the other for whom no common frontier exists and yet whose proximity creates the uncanny dispossession of home, the internal sense of an undoing. It speaks to the non-ground of community for which “I” and  “you”  are  not  individuals  of  a  common  concept.  Among  the  poem’s  diversity  of  dwellings, a “we” emerges to perform the fiction of a social bond. The Stranger departs and  returns  to  the  desert  –  there  where  hospitality  is  a  matter  of  life  or  death  –  but  his  utterance  remains  to  make  a  desert  of  those  dwellings  in  the  mind  where  sover-eign Identity lives as master; when for an instant astonishment makes Identity a guest.
title: Effects of undrained shear strength profile on retrogressive landslides in sensitive clays
Creators: name: Saha, Piash
Publisher: name: Memorial University of Newfoundland
Year: 2024

description: The undrained shear strength of normally and lightly overconsolidated clays generally increases with depth, which could significantly influence the failure of a slope. Large-scale landslides in sensitive clays generally occur by a successive failure of soil blocks, and the maximum depth of the sliding plane of these failure blocks typically reaches the level of the toe or slightly below the toe. The traditional limit equilibrium (LE) methods cannot model the progressive failure, and the typical Lagrangian-based finite element (FE) modelling technique cannot simulate the complete process of sensitive clay landslides because of significant mesh distortion around the failure planes. Eulerian-based FE simulations are performed in this study to investigate whether the initial undrained shear strength profile and strain-softening could be the cause of failure observed in sensitive clay landslides. To investigate the effects of the initial shear strength profile, the analyses are performed first for linearly increasing shear strength with depth for elastic perfectly plastic soil (i.e., no softening) with a relatively stronger soil layer below the toe. It is found that the shear strength gradient and depth of the stronger soil layer below the toe affect the location of the critical failure plane, the factor of safety, and the strength reduction factor in finite element analysis. For sensitive clay landslides, in addition to the depth and strength increase in the stronger clay layer below the toe, the rate of softening affects the failure plane formation and landslide extent. Higher strength and slower softening rate could be the cause of shallower failure of the soil blocks and a larger retrogression distance.
A stochastic chemical dynamic approach to correlate autoimmunity and optimal vitamin-D range

description: Motivated by several recent experimental observations that vitamin-D could interact with antigen presenting cells (APCs) and T-lymphocyte cells (T-cells) to promote and to regulate different stages of immune response, we developed a coarse grained kinetic model in an attempt to quantify the role of vitamin-D in immunomodulatory responses. Our kinetic model, developed using the ideas of chemical network theory, leads to a system of nine coupled equations that we solve both by direct and by stochastic (Gillespie) methods. Both the analyses consistently provide detail information on the dependence of immune response to the variation of critical rate parameters. We find that although vitamin-D plays a negligible role in the initial immune response, it exerts a profound influence in the long term, especially in helping the system to achieve a new, stable steady state. The study explores the role of vitamin-D in preserving an observed bistability in the phase diagram (spanned by system parameters) of immune regulation, thus allowing the response to tolerate a wide range of pathogenic stimulation which could help in resisting autoimmune diseases. We also study how vitamin-D affects the time dependent population of dendritic cells that connect between innate and adaptive immune responses. Variations in dose dependent response in anti-inflammatory and pro-inflammatory T-cell populations to vitamin-D correlate well with recent experimental results. Our kinetic model allows for an estimation of the range of optimum level of vitamin-D required for smooth functioning of the immune system and for control of both hyper-regulation and inflammation. Most importantly, the present study reveals that an overdose or toxic level of vitamin-D or any steroid analogue could give rise to too large a tolerant response, leading to an inefficacy in adaptive immune function.

An analysis of the agritourism industry in Western Newfoundland: potentials & impediments
Creators: name: Haghiri, Morteza
Publisher: name: Journal of Tourism & Development
Year: 2010

description: The Agriculture, Aquaculture and Fishery sector of Newfoundland and Labrador plays important role in terms of its contribution to the employment and gross domestic product despite the fact that the sector has recently been under enormous pressure from structural changes. Producers in Newfoundland and Labrador are facing a series of challenges, including high production costs arisen from increasing inputs prices, rules and regulations imposed by the federal and provincial governments, increased competition in output markets, and the turmoil of global economy. As a result, producers will have to find new ways that generate additional income to the on-farm revenues. Agritourism is one option that can potentially increase the incomes of small farms while preserving the viability of rural economies in the region. This paper aims to analyse the agritourism industry inWestern Newfoundland by conducting a comprehensive field survey during spring and summer 2008. The recommendations made from the results of this study provide new visions for policy makers to understand better the industry, recognise the impediments, and make appropriate decisions at the local and provincial level.

Entanglement and algebraic independence in fermion systems

description: In the case of systems composed of identical particles, a typical instance in quantum statistical mechanics, the standard approach to separability and entanglement ought to be reformulated and rephrased in terms of correlations between operators from subalgebras localized in spatially disjoint regions. While this algebraic approach is straightforward for bosons, in the case of fermions it is subtler since one has to distinguish between micro-causality, that is the anti-commutativity of the basic creation and annihilation operators, and algebraic independence that is the commutativity of local observables. We argue that a consistent algebraic formulation of separability and entanglement should be compatible with micro-causality rather than with algebraic independence.
