description: Photometric observations of 235 extragalactic objects that are potential targets for the Space Interferometry Mission (SIM) are presented. Mean B, V, R, I magnitudes at the 5% level are obtained at 1 - 4 epochs between 2005 and 2007 using the 1-m telescopes at Cerro Tololo Inter-American Observatory and Naval Observatory Flagstaff Station. Of the 134 sources which have V magnitudes in the Veron & Veron-Cetty catalog a difference of over 1.0 mag is found for the observed-catalog magnitudes for about 36% of the common sources, and 10 sources show over 3 mag difference. Our first set of observations presented here form the basis of a long-term photometric variability study of the selected reference frame sources to assist in mission target selection and to support in general QSO multi-color photometric variability studies.

Weaving the Space. The Deconstruction of the Metaphysic’s Veil
Creators: name: Vitale, Francesco
Publisher: name: ZoneModa Journal

Subjects: Deconstruction; Metaphysics; Fabric; Weave; Veil

description: The article in its first part aims to give an account of the introduction of the term “deconstruction” in the field of fashion and studies dedicated to it. Since “deconstruction” has spread like a virus in North American culture since the 1980s, it is intended to verify the congruence of this spread that has reached the fashion world through the success of architectural deconstructivism. Beyond various generic and superficial references, a certain interest in the work of fashion designer Martin Margela has been recognized. Starting from this general framework, an attempt was made to show what themes and resources “deconstruction” can offer to fashion studies, in particular through the reading of a text by Derrida dedicated to the figure of the “veil” in the tradition of Western culture.

description: L’articolo si propone di indagare la destrutturazione del corpo analizzando collezioni contemporanee di fashion designer che progettano abiti de-funzionalizzati, le cui forme non rimandano alla sintassi ordinaria del corpo (testa-torace-braccia-gambe). Per rispondere al quesito del perché il corpo immaginato da alcuni fashion designer sia diventato deforme e oltre-umano, nell’articolo si ipotizza che questi riflettano sul futuro e lo immaginino nella loro progettazione. Così l’articolo passa in rassegna una breve storia dei futuri immaginati dai fashion designer per approdare alla contemporaneità di cui si individuano due diverse linee immaginative: quella aliena (Iris Van Arpen, Thierry Mugler) e quella oltre-umana (Graig Green, Rei Kawakubo, Victor & Rolf e i fashion designer radicali presentati da NOT A TOY, Fashioning Radical Characters curata da Vassilis Zidianakis). Il tempo immaginato e il tempo attuale sono gli assi entro cui si muovono le collezioni qui prese in considerazione, proiettate in un futuro che permette, in un moto convulsivo che ricade su se stesso, di leggere e interpretare il tempo attuale. L’articolo ipotizza che la rivoluzione tecnologica partita in tempo moderno e giunta fino a oggi, l’era del post-modernismo, ha portato a un corpo non più percepito come familiare.

description: As an approach for redefining relations between text and its meaning, the idea of deconstruction appeared in the works of philosopher Jacques Derrida. This philosophical concept received the reflection in the modern architecture: it provokes a denial of stereotypes about the building’s forms and functions, a conflict of the architectural elements’ dislocation. Some fashion designers use a deconstruction method to destroy fashion standards and fashion stereotypes. Particularly, Belgian designer Martin Margiela questions the traditional understanding of fashion and fashion beauty and rethinks the relations between fashion forms, functions, and ideology constructed by clothing. This paper provides an analysis of the deconstructionist fashion techniques in the case of Maison Margiela fashion house. By performing the conflicting nature of fashion garments, Margiela constructs the concept of universal, basic clothes but, at the same time, very anonymous, free of labels, tags, and social judgments. This fashion of deconstruction articulates today the next level of relationship between consumers and fashion garments that is not only about standardized functions but expanded values and interpretations.

description: A new catalog of visual double systems containing eclipsing binaries as one component is presented. The main purpose of this catalog is to compile a complete list of all known multiples of this variety, both for current analysis and to highlight those in need of additional observations. All available photometric and astrometric data were analyzed, resulting in new orbits for eight systems and new times of minimum light for a number of the eclipsing binaries. Some of the systems in the catalog have acceptable solutions for their visual orbits, although in most cases their orbital periods are too long for simultaneous analysis. Also included, however, are a number of systems which currently lack an orbital solution but which may be suitable for simultaneous analysis in the future.

description: The Low Frequency Instrument on board the PLANCK satellite is designed to give the most accurate map ever of the CMB anisotropy of the whole sky over a broad frequency band spanning 27 to 77 GHz. It is made of an array of 22 pseudo-correlation radiometers, composed of 11 actively cooled (20 K) Front End Modules (FEMs), and 11 Back End Modules (BEMs) at 300K. The connection between the two parts is made with rectangular Wave Guides. Considerations of different nature (thermal, electromagnetic and mechanical), imposed stringent requirements on the WGs characteristics and drove their design. From the thermal point of view, the WG should guarantee good insulation between the FEM and the BEM sections to avoid overloading the cryocooler. On the other hand it is essential that the signals do not undergo excessive attenuation through the WG. Finally, given the different positions of the FEM modules behind the focal surface and the mechanical constraints given by the surrounding structures, different mechanical designs were necessary. A composite configuration of Stainless Steel and Copper was selected to satisfy all the requirements. Given the complex shape and the considerable length (about 1.5-2 m), manufacturing and testing the WGs was a challenge. This work deals with the development of the LFI WGs, including the choice of the final configuration and of the fabrication process. It also describes the testing procedure adopted to fully characterize these components from the electromagnetic point of view and the space qualification process they underwent. Results obtained during the test campaign are reported and compared with the stringent requirements. The performance of the LFI WGs is in line with requirements, and the WGs were successfully space qualified.

Computing the biases of parity-check relations

Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: A divide-and-conquer cryptanalysis can often be mounted against some keystream generators composed of several (nonlinear) independent devices combined by a Boolean function. In particular, any parity-check relation derived from the periods of some constituent sequences usually leads to a distinguishing attack whose complexity is determined by the bias of the relation. However, estimating this bias is a difficult problem since the piling-up lemma cannot be used. Here, we give two exact expressions for this bias. Most notably, these expressions lead to a new algorithm for computing the bias of a parity-check relation, and they also provide some simple formulae for this bias in some particular cases which are commonly used in cryptography.

description: We consider a continuous-time stochastic volatility model. The model contains a stationary volatility process, the multivariate density of the finite dimensional distributions of which we aim to estimate. We assume that we observe the process at discrete instants in time. The sampling times will be equidistant with vanishing distance. A multivariate Fourier-type deconvolution kernel density estimator based on the logarithm of the squared processes is proposed to estimate the multivariate volatility density. An expansion of the bias and a bound on the variance are derived. Key words: stochastic volatility models, multivariate density estimation, kernel estimator, deconvolution, mixing

The result is in agreement with the statistics of a thermal field of the same coherence length, and shows the feasibility of investigating photon statistics with compact cw-pumped sources. Implications for entanglement-based quantum cryptography are discussed.

description: Two-dimensional semiconductors inside optical microcavities have emerged as a versatile platform to explore new hybrid light-matter quantum states. The strong light-matter coupling leads to the formation of exciton-polaritons, which in turn interact with the surrounding electron gas to form quasiparticles called polaron-polaritons. Here, we develop a general microscopic framework to calculate the properties of these quasiparticles such as their energy and the interactions between them. From this, we give microscopic expressions for the parameters entering a Landau theory for the polaron-polaritons, which offers a simple yet powerful way to describe such interacting light-matter many-body systems. As an example of the application of our framework, we then use the ladder approximation to explore the properties of the polaron-polaritons. We furthermore show that they can be measured in a non-demolition way via the light transmission/reflection spectrum of the system. Finally, we demonstrate that the Landau effective interaction mediated by electron-hole excitation is attractive leading to red shifts of the polaron-polaritons. Our work provides a systematic framework to study exciton-polaritons in electronically doped two-dimensional materials such as novel van der Waals heterostructures.

Contemporary Fashion Imaginary. Deconstructing Gender
Creators: name: Di Sandro, Nicole
Publisher: name: ZoneModa Journal
Year: 2020
Subjects: Gender; Meaning; Performativity; Identity Politics; Fluidity

description: Argued by Jacques Derrida, Deconstruction is a critical practice of reading and rewriting meanings: it aims to the decomposition of linguistic systems, by unveiling the function of oppositional categories. Integrating the Judith Butler deconstructive approach to gender identity and its performativity, the essay explores the mechanisms of social determining processes over subjects, defining to which extent fashion participates in gender intelligibility and projection of Self within the society. Along the analysis of Zanaughtti and Knight’s fashion film Disrupt, Distort, Disguise, the paper inquires provocative queering practices that reject any fixed, essential way of being man or woman. According to Butler’s studies, it unfolds the very fallacy of ‘gender’ noun, its binarity and hierarchical order: gender is a continuous process of citation and alteration, and it is all about doing. As in the movie, such imitative structure is implicitly revealed by Cross-Dressing performances: a parody of heterosexual pre-existing codes, denying the idea of stable Self and its forced naturalization. These insights are traceable in the continuous becoming and negotiation of dressing practices: embracing the fluidity of gender, fashion imaginary is blurring the line between masculine and feminine, acting a political mediation between social structural changes and the related discriminating resistance.

description: The spin-noise spectroscopy (SNS) method implies high efficiency of conversion of the spin-system magnetization to the Faraday rotation angle. Generally, this efficiency cannot be estimated using the characteristics of the regular magneto-optical activity of a paramagnet. However, it may be drastically enhanced in systems with strong inhomogeneous broadening of the optical transitions. This enhancement leads to the giant spin-noise gain effect and previously allowed one to apply the SNS to rare-earth-activated crystals. We show that the nonlinear resonant Faraday effect can be used to measure the homogeneous width of the inhomogeneously broadened transition and, thus, to estimate the applicability of the SNS to this type of paramagnet. We present the theoretical description of the effect and perform measurements on intraconfigurational ($4f$-$4f$) transitions of the trivalent rare-earth ions of neodymium and ytterbium in fluorite-based crystals. The proposed experimental approach establishes new links between the effects of nonlinear optics and spin-noise characteristics of crystals with paramagnetic impurities and offers new ways of research in the physics of impurity crystals.

Huang Tsun-Hsien’s interpretation of Mieji Japan’s economic development : an early stage of China’s intellectual response to modern Japan
Creators: name: Lee, Ching-Man
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is an attempt to analyse the conscious response of a Chinese intellectual—Huang Tsun-hsien—to Meiji Japan and its relation to some aspects of the historical situation of China in the last two decades of the nineteenth century. It includes, in the first place, an examination of Huang Tsun-hsien as a typical example of China's intellectual response to Japan in the late nineteenth century. His "Jih-pen kuo-chih" (Treaties on Japan)" was the first systematic study on Japanese history which was used as a blueprint for the Hundred Days Reform in 1898. Huang was one of the precursory Chinese who seriously recommended Japan as a model of modernization for China. An effort is made to evaluate his interpretation of Japan-by analyzing the relevant portions of the "Jih-pen Kuo-chih" and comparing his image of Meiji economic development with the situation in reality. In examining the implications of Huang's reform proposals, we not only reconstruct the intellectual atmosphere of his time but also trace the evolution of Chinese economic concepts. A general contour of late Ch'ing economic thought, i.e. the ching-shih (practical statecraft), yang-wu (self-strengthening) and Shang-wu (mercantilism and industrialism) is drawn. By placing Huang as an economic reformer against such a background, we hope to find out the position he occupied in this trend. The findings of this thesis are: (1) Huang's response to Japan was basically a reflection of his concern for China's indigenous problems and a projection of his preoccupation with the searching for a workable formula that would bring wealth and power to China. This thesis suggests a better understanding of the Chinese intellectuals' response to Japan by probing deeper into the built-in perspective of the Chinese; (2) Huang was an incisive observer of the Japanese economic development though the explanation he offered was somewhat distorted by his preoccupations with China's problems. His failure to analyze the applicability of the Japanese model to China demonstrated China's difficulties in borrowing and adapting Japanese and Western ways of modernization, and (3) Huang was a shang-wu thinker with a ching-shih intellectual commitment and a yang-wu career background. His significant contribution was in introducing to China the economic experience of the Japanese in their modernization.
Time, Cruelty and Destruction in Deconstructivist Fashion: Kawakubo, Margiela and Vetements

Subjects: Deconstructionist fashion; Silhouette; Destruction; Time; Critical fashion practice

description: It is generally agreed that deconstruction in fashion was ushered in by the first major collections of Rei Kawakubo (Comme des Garçons) in the early 1980s. Kawakubo, together with Vivienne Westwood and Martin Margiela revolutionised fashion by turning their back on finery and preciousness in favour of a fundamentally aberrant sartorial language that suggested impoverishment, discontinuity and discord. However, these three designers came to this aesthetic in differing ways and intentions. As we argue in detail in Critical Fashion Practice (2017) Kawakubo’s (and Martin Margiela’s) approach can be strongly aligned to the philosophies of deconstruction as advanced by Jacques Derrida, and more specifically to deconstructivism which is the more structural and practical application of deconstructionist principles when applied to architecture. Kawakubo’s deconstructivist approach destabilises binaries of inside-outside, body-clothing, old-new, worn and discarded, and so on. Kawakubo’s ground-breaking designs went on to influence Margiela who would revolt against the holy scriptures of couture by experimenting with silhouettes, reversing linings and hems inside out and experimenting with oversized proportions. Just as Derridean approaches to philosophy, literature and cultural theory influenced feminist and postcolonial scholars, so too has Kawakubo and Margiela influenced several generations of designers and such as Demna Gvasalia of Vetements, who have not only followed Margiela’s example but continues to expand the notion of what clothing, fashion and dress means, functions and signifies in the Anthropocene age.

As an application, we use semiquandle invariants to compare two Vassiliev invariants.

description: The formation of water molecules from the reaction between ozone (O3) and D-atoms is studied experimentally for the first time. Ozone is deposited on non-porous amorphous solid water ice (H2O), and D-atoms are then sent onto the sample held at 10 K. HDO molecules are detected during the desorption of the whole substrate where isotope mixing takes place, indicating that water synthesis has occurred. The efficiency of water formation via hydrogenation of ozone is of the same order of magnitude of that found for reactions involving O atoms or O2 molecules and exhibits no apparent activation barrier. These experiments validate the assumption made by models using ozone as one of the precursors of water formation via solid-state chemistry on interstellar dust grains.

description: We calculate the tunneling process of a Dirac particle across two square barriers separated a distance $d$, as well as the scattering by a double cusp barrier where the centers of the cusps are separated a distance larger than their screening lengths. Using the scattering matrix formalism, we obtain the transmission and reflection amplitudes for the scattering processes of both configurations. We show that, the presence of transmission resonances modifies the Lorentizian shape of the energy resonances and induces the appearance of additional maxima in the transmission coefficient in the range of energies where transmission resonances occur. We calculate the Wigner time-delay and show how their maxima depend on the position of the transmission resonance.

description: In the solar atmosphere the twist parameter $α$ has the same sign as magnetic helicity. It has been observed using photospheric vector magnetograms that negative/positive helicity is dominant in the northern/southern hemisphere of the Sun. Chromospheric features show dextral/sinistral dominance in the northern/southern hemisphere and sigmoids observed in X-rays also have a dominant sense of reverse-S/forward-S in the northern/southern hemisphere. It is of interest whether individual features have one-to-one correspondence in terms of helicity at different atmospheric heights. We use UBF \Halpha images from the Dunn Solar Telescope (DST) and other \Halpha data from Udaipur Solar Observatory and Big Bear Solar Observatory. Near-simultaneous vector magnetograms from the DST are used to establish one-to-one correspondence of helicity at photospheric and chromospheric heights. We plan to extend this investigation with more data including coronal intensities.

description: We develop the Hamiltonian theory of axial perturbations around a general time-dependent spherical background spacetime. Using the fact that the linearized constraints are gauge generators, we isolate the physical and unconstrained axial gravitational wave in a Hamiltonian pair of variables. Then, switching to a more geometrical description of the system, we construct the only scalar combination of them. We obtain the well-known Gerlach and Sengupta scalar for axial perturbations, with no known equivalent for polar perturbations. The strategy suggested and tested here will be applied to the polar case in a separate article.

description: We analyse a compressible Poiseuille flow of ideal gas in a plane channel. We provide the form of internal energy U for a non-equilibrium stationary state (NESS) that includes viscous dissipation and pressure work. We demonstrate that U depends strongly on the ratio Δp/p_0, where Δp is the pressure difference between inlet and outlet and p_0 is the outlet's pressure. In addition, U depends on two other variables: the channel aspect ratio and the parameter equivalent to Reynolds number. The stored internal energy, ΔU=U-U0, is small compared to the internal energy U0 of the equilibrium state (ES) for a moderate range of values of Δp/p_0. However, ΔU can become large for big Δp or close to vacuum conditions at the outlet (p_0~0 Pa).

description: Fashion as mirror of socio-cultural evolutions. In light of the ever-increasing plurality and hybridization of languages, fashion change, through disassembling and reconstruction actions according to creative processes capable of generating new design approaches. The creative process, having passed the phase of revival, rediscovery and re-proposal of styles, today acts more and more according to an approach far from citationism. A method that deconstructs and reassembles products, materials and styles, in a mash-up, generating new signs, meanings and shapes, that recall, but do not refer didactically to precise references. Shapes, symbols, textures are thus deconstructed and recomposed according to logics and approaches that generate a multiplicity of meanings. Brands such as Vetements, Off-White, United Standard, Marcelo Burlon borrow from music not only cultural references but also a design approach. There is a form of deconstruction that looks more like a music mix using techniques such as Fading, Harmonic Mixing, Slicing, Swap or Looping. Thus a new identity of contemporary fashion takes shape: we witness to a meta-design process that, thanks to a group of emerging figures hovering between DJs and fashion designers, defines an idea of deconstruction according to approaches that owe much to consoles, mixers, and synthesizers.

Middleware per la gestione di interfacce di comunicazione e di sorgenti di contesto in ambienti wireless eterogenei

Subjects: ING-INF/05 Sistemi di elaborazione delle informazioni

description: The full exploitation of multi-hop multi-path connectivity opportunities offered
by heterogeneous wireless interfaces could enable innovative Always Best Served
(ABS) deployment scenarios where mobile clients dynamically self-organize to
offer/exploit Internet connectivity at best. Only novel middleware solutions based
on heterogeneous context information can seamlessly enable this scenario:
middleware solutions should i) provide a translucent access to low-level
components, to achieve both fully aware and simplified pre-configured
interactions, ii) permit to fully exploit communication interface capabilities, i.e.,
not only getting but also providing connectivity in a peer-to-peer fashion, thus
relieving final users and application developers from the burden of directly
managing wireless interface heterogeneity, and iii) consider user mobility as
crucial context information evaluating at provision time the suitability of available
Internet points of access differently when the mobile client is still or in motion.
The novelty of this research work resides in three primary points. First of all, it
proposes a novel model and taxonomy providing a common vocabulary to easily
describe and position solutions in the area of context-aware autonomic
management of preferred network opportunities.
Secondly, it presents PoSIM, a context-aware middleware for the synergic
exploitation and control of heterogeneous positioning systems that facilitates the
development and portability of location-based services. PoSIM is translucent, i.e.,
it can provide application developers with differentiated visibility of data
characteristics and control possibilities of available positioning solutions, thus
dynamically adapting to application-specific deployment requirements and
enabling cross-layer management decisions.
Finally, it provides the MMHC solution for the self-organization of multi-hop
multi-path heterogeneous connectivity. MMHC considers a limited set of practical
indicators on node mobility and wireless network characteristics for a coarsegrained
estimation of expected reliability/quality of multi-hop paths available at
runtime. In particular, MMHC manages the durability/throughput-aware formation
and selection of different multi-hop paths simultaneously. Furthermore, MMHC
provides a novel solution based on adaptive buffers, proactively managed based on
handover prediction, to support continuous services, especially by pre-fetching
multimedia contents to avoid streaming interruptions.

description: The phase is one of the fundamental properties of a wave that allows to control interference effects and can be used to efficiently encode information. We examine numerically a magnonic resonator of the Gires-Tournois interferometer type, which enables the control of the phase of spin waves reflected from the edges of the ferromagnetic film. The considered interferometer consists of a Py thin film and a thin, narrow Py stripe placed above its edge, both coupled magnetostatically. We show that the resonances and the phase of the reflected spin waves are sensitive for a variation of the geometrical parameters of this bi-layerd part of the system. The high sensitivity to film, stripe, and non-magnetic spacer thicknesses, offers a prospect for developing magnonic metasurfaces and sensors.
An ’enlightened’ Scot and English reform : a study of Henry Brougham
Creators: name: Dwyer, John Alfred
Publisher: name: University of British Columbia
Year: 2010

description: Henry Peter Brougham (1708-1868) has always received more than his fair share of attention from historians. However, as we shall attempt to show, his role as a social reformer in England has not been treated properly. Historians have viewed Brougham in different ways. They have called him a humanitarian, a Benthamite, and a middle-class apologist. They have never taken his Scottish background or his training at Edinburgh University adequately into account. As a result, these historians have overlooked an interesting example of the influence of Scottish thought and practice in English reform movements. The present study is an attempt to examine Henry Brougham in the light of his Scottish heritage. By isolating those factors in Brougham's Scottish experience which were to have a bearing on his efforts in behalf of social reform in England, we hope to construct a composite picture of Brougham as an 'enlightened Scot'. The first chapter of the thesis deals with Scottish culture in a fairly general way. Here, we attempt to define the peculiar aspects of the Scottish identity and to explore the development of 'moral' or 'common sense' philosophy by the thinkers of the Scottish School. In addition, we show how Brougham, as a member of the 'Edinburgh literati.' and a student of Black and Stewart, was a true exemplar of this culture. In chapter two, we examine the specifically Scottish institutions of law, poor relief, and education in some depth. These institutions ingrained deep attitudes in the minds of Scots such as Brougham. Furthermore, in every case, the Scots believed that their own institutions were vastly superior to those of England. Having outlined Brougham's 'mental baggage', we then move on to demonstrate the ways in which Brougham's work as a social reformer in England reflected his Scottish heritage. For, it is quite clear that his ideas were very much informed by Scottish theory and practice. First, as a legal reformer, Brougham evidenced his training as a Scots lawyer. Like Mansfield before him, he looked to Roman law as a remedy for the chaotic condition of English Common law. Second, in his attack on the English Poor Law, Brougham was forever contrasting the English system of institutionalized relief with the voluntary system of Scotland. Moreover, his training in political economy at Edinburgh University caused him to regard institutionalized relief as a hindrance to economic advance. Finally, as the leader of the movement for mass education in England, Brougham attempted to create a national system of education on the Scottish model. And his pride in Scottish parochial education was buttressed by an 'enlightened' faith in the power of education to shape men.

description: In March 2007 the assembly of the Silicon Strip Tracker was completed at the Tracker Integration Facility at CERN. Nearly 15% of the detector was instrumented using cables, fiber optics, power supplies, and electronics intended for the operation at the LHC. A local chiller was used to circulate the coolant for low temperature operation. In order to understand the efficiency and alignment of the strip tracker modules, a cosmic ray trigger was implemented. From March through July 4.5 million triggers were recorded. This period, referred to as the Sector Test, provided practical experience with the operation of the Tracker, especially safety, data acquisition, power, and cooling systems. This paper describes the performance of the strip system during the Sector Test, which consisted of five distinct periods defined by the coolant temperature. Significant emphasis is placed on comparisons between the data and results from Monte Carlo studies.

description: Based on the unrestricted Gutzwiller approximation we study the possibility that the diagonal incommensurate spin scattering in the spin glass phase of lanthanum cuprates originates from stripe formation. Similar to the metallic phase two types of diagonal stripe structures appear to be stable: (a) site-centered textures which have one hole per site along the stripe and (b) ferromagnetic stair-case structures which are the diagonal equivalent to bond-centered stripes in the metallic phase and which on average have a filling of 3/4 holes per stripe site. We give a detailed analysis of the stability of both diagonal textures with regard to the vertical ones.

Dynamics of two quantized vortices belonging to different components of binary Bose-Einstein condensates in a circular box potential

description: This study aims to research on dynamics of two quantized vortices in miscible two-component Bose--Einstein condensates, trapped by a circular box potential by using the Gross--Pitaevskii equation. We consider a situation in which two vortices belong to different components and they are initially close. Their dynamics are significantly different from those of a vortex pair in a single-component condensate. When two vortices are initially co-located, they are split by dynamical instability or remain co-located depending on their intercomponent interaction. If the two split vortices have the same sign of circulation, they rotate around each other. Then, the angular velocity can be given as a function of the distance between two vortices, which is understood through the equations of motion and their interaction. If the circulations of two close vortices have different signs, however, they move in the same direction initially, then overlap during the dynamics. This subsequent overlap can be categorized into two types based on the initial distance between them. The mechanism of this overlapping can be understood from the interaction between the vortex and its image vortex, which makes the two vortices close to each other even if the intrinsic interaction between them is repulsive.

The pre-war Japanese Canadians of Maple Ridge : landownership and the KEN tie
Creators: name: Read, John Mark
Publisher: name: University of British Columbia
Year: 2010

description: This paper is an examination of the ethnic clustering and landownership patterns of the pre-war Japanese Canadian berry farmers in the District of Maple Ridge, British Columbia. In this particular area the Japanese Canadian farmers clustered together in three distinct areas and established Nokai or agricultural associations to look after their economic needs. These Nokai were both geographic centres and social centres as they were centrally located in the cluster and the Nokai building became the Japanese community's meeting place. These clusters of Japanese appear to be a product of Canadian racial prejudice and strong ethnic ties. In addition to being clustered together ethnically these Japanese Canadian farmers have a landownership pattern that displays a persistence of regional loyalty. Most of the Japanese Canadian farmers have tended to locate their farms near someone of the same prefectural origins. This geographic expression of Japanese regional loyalty in North America has never been noticed. The apparent persistence of this Ken-tie, as demonstrated in these farmer's landownership pattern, indicates that regional loyalty or Zen-consciousness is an important element in the set of values of the Japanese immigrant and his family.

Strategie competitive e modelli organizzativi dei Confidi alla luce del nuovo quadro normativo

Year: 2008
Subjects: SECS-P/11 Economia degli intermediari finanziari

description: In Italia, il contesto legislativo e l’ambiente competitivo dei Confidi è profondamente mutato negli ultimi
anni a seguito dell’emanazione di due nuove normative: la “Legge Quadro” sui Confidi e la nuova
regolamentazione del capitale di vigilanza nelle banche (c.d. "Basilea 2").
la Legge Quadro impone ai Confidi di adottare uno dei seguenti status societari: i) ente iscritto all’albo di
cui all’art. 106 del Testo Unico Bancario (TUB); ii) ente iscritto all’albo di cui all’art. 107 del Testo Unico
Bancario; iii) banca cooperativa di garanzia collettiva dei fidi. Fermi restando i requisiti soggettivi sui
garanti ammessi da Basilea 2, la modalità tecnica finora utilizzata dai Confidi non risponde ai requisiti
oggettivi.
Il pensiero strategico si enuclea nelle seguenti domande: A) qual è la missione del Confidi (perché
esistono i Confidi)? B) Quali prodotti e servizi dovrebbero offrire per raggiungere la loro missione? C)
Quale modello organizzativo e di governance si conforma meglio per l'offerta dei prodotti e servizi
individuati come necessari per il raggiungimento della missione?
Le riflessioni condotte nell’ambito di un quadro di riferimento delineato dal ruolo delle garanzie nel
mercato del credito bancario, dalle “Nuove disposizioni di vigilanza prudenziale per le banche”, dalla
“Legge Quadro” sui e, infine, dall’assetto istituzionale ed operativo dei Confidi si riassumono nelle
seguenti deduzioni:
Proposizione I: segmentare la domanda prima di adeguare l’offerta;
Proposizione II: le operazioni tranched cover sono un'alternativa relativamente efficiente per
l'operatività dei Confidi, anche per quelli non vigilati;
Proposizione III: solo i Confidi‐banca hanno la necessità di dotarsi di un rating esterno;
Proposizione IV: le banche sono nuovi Clienti dei Confidi: offrire servizi di outsourcing (remunerati), ma
non impieghi di capitale;
Proposizione V: le aggregazioni inter settoriali nel medesimo territorio sono da preferirsi alle
aggregazioni inter territoriali fra Confidi del medesimo settore.
Alle future ricerche è affidato il compito di verificare: quali opzioni strategiche nel concreato siano state
applicate; quali siano state le determinati di tali scelte; il grado di soddisfacimento dei bisogni degli
stakeholder dei Confidi; misurare i benefici conseguiti nell'efficienza allocativa del credito.
