description: The mechanisms of energy and spin transfer in quantum dot pairs coupled via the Coulomb interaction are studied. Exciton transfer can be resonant or phonon-assisted. In both cases, the transfer rates strongly depend on the resonance conditions. The spin selection rules in the transfer process come from the exchange and spin-orbit interactions. The character of energy dissipation in spin transfer is different than that in the traditional spin currents. The spin-dependent photon cross-correlation functions reflect the exciton transfer process. In addition, a mathematical method to calculate Förster transfer in crystalline nanostructures beyond the dipole-dipole approximation is described.

description: In addition to the age factor and the way in which the passage of time and history can be seen as a succession of generations, the concept of generation must also be thought of as a mode of classification that is necessarily contested. Immigration poses a question of generation that is special in that it, firstly, involves the addition of an external factor in the evolution of a society and, secondly, involves the creation of a new type of generational identification within that society. The social milieu of immigrants therefore represents a laboratory where all the latent meanings engendered by the relationships between the individuals and the group and between the different generations may be studied.

description: We report the superconductivity of PbTaS2 single crystals with the centrosymmetric structure. The systematic measurements of magnetization, electric transport and specific heat indicate that PbTaS2 is a weakly coupled type-II superconductor with transition temperature Tc = 2.6 K. Furthermore, the band structure calculations predicted four nodal lines near the Fermi energy with drumhead-like surface states, suggesting centrosymmetric PbTaS2 is a candidate of topological nodal line semimetals. These results demonstrate that PbTaS2 may open up another avenue for further exploring the properties of superconductivity and topological nodal-line states.

description: This paper examines the optimal allocation of several inputs in the context of seawater desalination by reverse osmosis (RO) as a source of municipal (or commercial or industrial) water. A cost-minimization model is developed, a production function is estimated, and sensitivity analyses are conducted using the optimization model to investigate the effect of environmental conditions and economic factors on the optimal input portfolio and the cost of operating a modeled seawater desalination facility. The objectives of this paper are to better understand the effect on the seawater desalination facility’s costs and input portfolio from changes in water quality, membrane lifespan, daily operations schedule, and energy prices. Findings include that lower total facility costs are associated with warm-weather water quality parameters, longer membrane life, and mid-range daily operations schedule (14.265 hours/day). Under most conditions, an interruptible power supply regime reduces facility costs. Exceptions include when the interruptible power supply regime implies significant reductions in operating hours and the associated reduction in energy price is very small.
On the energy landscape at the glass transition

description: A recent hypothesis claims that the glass transition itself, though it is a very pronounced relaxation peak, is no separate relaxation process at all, but is just the breakdown of the shear modulus due to the weak elastic dipole interaction between all the quasi-independent relaxation centers of the glass. Two derivations are considered, one of them in terms of a breakdown of the shear modulus and the second in terms of a divergence of the shear compliance. Mechanical relaxation data from the literature for vitreous silica, glycerol, polymethylmethacrylate and polystyrene are found to be consistent with the first hypothesis.

The Fathers’ Illusion of Redemption, Their Children’s Perception of Pain: Migratory, Family, and Intergenerational Trajectories of Italian-Bangladeshis Relocating to London
Creators: name: Della Puppa, Francesco
Publisher: name: Italian Sociological Review
Year: 2025

description: This article is the result of a broader research project on the onward migration of Bangladeshi migrants in Italy who, once they have acquired Italian citizenship – and so a European passport – set off on a new migration to London, just before the “Brexit” referendum. The empirical evidence for the article comes from 40 in-depth interviews 1) with Italian-Bangladeshi men who have either already onward-migrated or are planning on doing so, and 2) with some of their children. The main motivation for this onward migration is the investment of first-migrant fathers in their children. Born and socialized in Italy, this so-called “second generation” have formal Italian citizenship, but are still subjected to processes of racialization and experience discrimination in public spaces and in political and media debates, and are also at risk of following their fathers into unskilled factory work, despite having acquired educational qualifications. The strategy for dealing with this “effect of destiny” is a “leap forward” into a context perceived – and idealized – as more meritocratic and governed by multiculturalism in which their presence would not need to be justified. However, the new migration is experienced by their children as a form of uprooting, similar to what their fathers experienced.

description: COMPASS is a new fixed target experiment presently in operation at CERN. It has the goal to investigate hadron structure and hadron spectroscopy by using either muon or hadron beams. From measurements of various hadron asymmetries in polarized muon - nucleon scattering it will be possible to determine the contribution of the gluons to the nucleon spin. Main objective of the hadron program is the search of exotic states, and glueballs in particular. This physics programme is carried out with a two-stage magnetic spectrometer, with particle identification and calorimetry in both stages, which has started collecting physics data in 2002, and will run at the CERN SPS at least until 2010. Preliminary results from the 2002 run with a 160 GeV muon beam are presented for several physics channels under investigation.

description: We analyze the kinematics of electron-positron production in a photon-photon interaction when one has a modification of the special relativistic kinematics as a power expansion in the inverse of a new high-energy scale. We derive the equation for the threshold energy of this reaction to first order in this expansion, including the effects due to a modification of the energy-momentum conservation equation. In contrast with the Lorentz invariance violation case, a scale of the order of a few TeV is found to be compatible with the observations of very high-energy cosmic gamma rays in the case of a modification compatible with the relativity principle.

description: We obtain a classification of elliptic operators modulo stable homotopy on manifolds with edges (this is in some sense the simplest class of manifolds with nonisolated singularities). We show that the operators are classified by the K-homology group of the manifold. To this end, we construct exact sequence in elliptic theory isomorphic to the K-homology exact sequence. The main part of the proof is the computation of the boundary map using semiclassical quantization.

description: The entropy region is a fundamental object in information theory. An outer bound for the entropy region is defined by a minimal set of Shannon-type inequalities called elemental inequalities also referred to as the Shannon region. This paper focuses on characterization of the entropic points at the boundary of the Shannon region for three random variables. The proper faces of the Shannon region form its boundary. We give new outer bounds for the entropy region in certain faces and show by explicit construction of distributions that the existing inner bounds for the entropy region in certain faces are not tight.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The topic of this review is the current state of our knowledge about the degree of initial equilibration between electrons, protons and ions at supernova remnant (SNR) shocks. Specifically, the question has been raised as to whether there is an inverse relationship between the shock velocity and the equilibration similar to the relationship between equilibration and Alfven Mach number seen in interplanetary shocks (Schwartz et al 1988). This review aims to compile every method that has been used to measure the equilibration and every SNR on which they have been tested. I review each method, its problems and uncertainties and how those would effect the degree of equilibration (or velocity) inferred. The final compilation of observed electron to proton temperature ratios as a function of shock velocity gives an accurate, conservative picture of the state of our knowledge and the avenues we need to pursue to make progress in our understanding of the relation between the velocity of a shock and the degree of equilibration.

Measuring leisure among individuals with spinal cord injuries
Creators: name: Botner, Erica M.
Publisher: name: University of British Columbia
Year: 2009

description: Experiencing a spinal cord injury (SCI) results in many changes that may challenge an individual's ability to participate in leisure. Despite the benefits, leisure has been largely overlooked in rehabilitation research because it is difficult to measure. Scales exist that measure leisure behaviour; however, few have been tested for reliability and validity and even fewer have been developed for use among individuals with SCI. The purpose of this thesis was to: (1) evaluate the usability of the four scales in the Idyll Arbor Leisure Battery (LALB) using qualitative methodology; (2) provide estimates of the reliability of the IALB; and (3) provide support for the validity of the IALB in a sample of individuals with SCI. The IALB consists of four previously-developed scales that measure leisure attitude, leisure motivation, leisure satisfaction, and leisure interests. Qualitative evaluation raised some concerns with the IALB scales such as burden and the wording of the instructions and items. Several modifications were suggested. In the measurement study, forty-one individuals with SCI who had been discharged from inpatient rehabilitation at least one year prior to recruitment completed the leisure scales on two separate occasions. Test-retest reliability for the total scales and for most of the subscales was within an acceptable range for using the scales in descriptive research settings (ICCs > 0.75) and some evidence for their clinical use was discussed. When validated using standard measures of life satisfaction, depression, community integration, and leisure participation, most correlations were of the hypothesized magnitude and direction. Interrelationships among the IALB variables were also as expected providing support for the validity of the scales. Finally, although some problems were identified, factor analyses provided support for the previously defined factor structures of the IALB scales. The results provided evidence that the IALB has the potential to be a useful in measuring leisure attributes among individuals with SCI in both research and clinical settings. With some minor modifications, the psychometric properties of the scales may improve and the burden to individuals with SCI, clinicians, and researchers may diminish. Measurement standards, suggestions for modifications, and appropriate administration of the scales are discussed.

description: We use laboratory market experiments to control for market power and social norms in order to evaluate market outcomes associated with subsidy incidence. We estimate the incidence of a stylized agricultural subsidy in laboratory land rental negotiations and compare the market behavior of university students to agricultural professionals. In separate sessions with both subject groups, 21.5 percent of a per-unit subsidy paid to the buyer (tenant) was passed on to sellers (landlords). The consistent treatment effect between students and professionals is encouraging, particularly in the use of experimental laboratory methods for ex ante analyses of agricultural policy impacts.

description: We report the result of experiments designed to assess the effect of initial endowments on willingness to pay values elicited from multi-unit Vickrey auctions. Comparing bids from an “endow and upgrade” approach with the “full bidding” approach, we find that the direction of the endowment effect generally depends on the number of endowed units of the conventional product that subjects are willing to give up in exchange for units of the upgraded product. The endowment effect is “reverse” when the number of units that participants are willing to give up is lower or equal to the number of remaining endowed units. However, we generally find an endowment effect when the number of units a participant is willing to give up is higher than the number of remaining endowed units.

description: The provided data can be used to analyze changes to extreme atmospheric river events on the US West Coast in both HadAM4 and CESM2 and re-create figures from the study "Changes to Atmospheric River Related Extremes over the United States West Coast under Anthropogenic Warming". HadAM4 data uses a 0.83° x 0.56° horizontal grid resolution and a 6-hour temporal resolution. It uses historical forcing from the early 21st century, a 1.5°C increase from preindustrial levels, and a 2° increase from preindustrial levels, using the HAPPI framework. CESM2 uses a 1.25° x 0.94° horizontal grid resolution and a 6-hour temporal resolution. It uses a historical forcing scenario and the SSP 3-7.0 forcing scenario. Weather regimes calculated from mean sea level pressure fields and extreme event frequency during each weather regime from the HadAM4 data is also provided.

We find that the (magnon mediated) hole-hole interactions have an important effect on the region of charge stability in the space of parameters t',t'', generally increasing stability, while the stability in the magnetic sector is guaranteed by the presence of spin quantum fluctuations (order from disorder effect). These conclusions are based on perturbative analysis performed up to two loops, with very good convergence.

description: We note that in a system far from equilibrium the interface roughening may depend on the system size which plays the role of control parameter. To detect the size effect on the interface roughness, we study the scaling properties of rough interfaces formed in paper combustion experiments. Using paper sheets of different width λL, we found that the turbulent flame fronts display anomalous multi-scaling characterized by non universal global roughness exponent αand the system size dependent spectrum of local roughness exponents,ξ_q, whereas the burning fronts possess conventional multi-affine scaling. The structure factor of turbulent flame fronts also exhibit unconventional scaling dependence on λThese results are expected to apply to a broad range of far from equilibrium systems, when the kinetic energy fluctuations exceed a certain critical value.

description: Single crystals of Ca[Co_(2-x)Ir_(x)]_(2-y)As2 with 0 <= x <= 0.35 and 0.10 <= y <= 0.14 have been grown using the self-flux technique and characterized by single-crystal x-ray diffraction (XRD), energy-dispersive x-ray spectroscopy, magnetization M and magnetic susceptibility chi measurements versus temperature T, magnetic field H, and time t, and heat capacity Cp(H,T) measurements. The XRD refinements reveal that all the Ir-substituted crystals crystallize in a collapsed-tetragonal structure as does the parent CaCo_(2-y)As2 compound. A small 3.3% Ir substitution for Co in CaCo_(1.86)As2 drastically lowers the A-type antiferromagnetic (AFM) transition temperature TN from 52 to 23 K with a significant enhancement of the Sommerfeld electronic heat-capacity coefficient. The positive Weiss temperatures obtained from Curie-Weiss fits to the chi(T>TN) data indicate that the dominant magnetic interactions are ferromagnetic (FM) for all x. A magnetic phase boundary is inferred to be present between x = 0.14 and x = 0.17 from a discontinuity in the x dependences of the effective moment and Weiss temperature in the Curie-Weiss fits. FM fluctuations that strongly increase with increasing x are also revealed from the chi(T) data. The magnetic ground state for x >= 0.17 is a spin glass as indicated by hysteresis in chi(T) between field-cooling and zero-field-cooling measurements and from the relaxation of M in a small field that exhibits a stretched-exponential time dependence. The spin glass has a small FM component to the ordering and is hence inferred to be comprised of small FM clusters. A logarithmic T dependence of Cp at low T for x = 0.14 is consistent with the presence of significant FM quantum fluctuations. This composition is near the T = 0 boundary at x = 0.16 between the A-type AFM phase containing ferromagnetically-aligned layers of spins and the FM cluster-glass phase.

description: In this paper we estimate the impact the CAP subsidies on farm bank loans. According to the theoretical results, if subsidies are paid at the beginning of the growing season they may reduce bank loans, whereas if they are paid at the end of the season they increase bank loans, but these results are conditional on whether farms are credit constrained and on the relative cost of internal and external financing. In empirical analysis we use the FADN farm level panel data to test the theoretical predictions for period 1995-2007. We employ the fixed effects and GMM models to estimate the impact of subsidies on farm loans. The estimated results suggest that (i) subsidies influence farm loans and the effects tend to be non-linear and indirect; (ii) both coupled and decoupled subsidies stimulate long-term farm loans, but the long-term loans of big farms increase more than those of small farms due to decoupled subsidies; (iii) the short-term loans are affected only by decoupled subsidies, and they are altered by decoupled subsidies more for small farms than for large farms; however (v) when controlling for the endogeneity, only the decoupled payments affect loans and the relationship is non-linear.

description: The Zakharov-Kuznetsov equation in spatial dimension $d\geq 5$ is considered. The Cauchy problem is shown to be globally well-posed for small initial data in critical spaces and it is proved that solutions scatter to free solutions as $t \to \pm \infty$. The proof is based on i) novel endpoint non-isotropic Strichartz estimates which are derived from the $(d-1)$-dimensional Schrödinger equation, ii) transversal bilinear restriction estimates, and iii) an interpolation argument in critical function spaces. Under an additional radiality assumption, a similar result is obtained in dimension $d=4$.
Within the State and Without the Nation: Unraveling the Nation-State’s Dual Role in the Lives of Migrant Descendants Through Sayad’s Critical Sociology
Creators: name: SAJIR, ZAKARIA

Publisher: name: Italian Sociological Review
Year: 2025

description: This article examines the dual identity challenges of migrant descendants within the system of immigration built by nation-states, drawing on Abdelmalek Sayad’s critical sociology of migration. It highlights the tension between their status as legally recognised citizens and culturally marginalised ‘others’. The discussion underlines the nation-state’s struggle to reconcile its homogeneous national identity ideals with the realities of global migration, often failing to integrate these individuals fully. Central to this analysis is the distinction between ‘state’—legal-political institutions—and ‘nation’—cultural-linguistic identities. This division places migrant descendants in a liminal space, navigating their dual identities as insiders and outsiders. The article critiques the conventional integration paradigm that places the onus of assimilation on these individuals, suggesting that nation-states should instead adapt their structures for true inclusivity. The paper calls for reevaluating the nation-state, proposing a more inclusive and pluralistic approach to national identity that acknowledges the layered identities of all citizens, especially migrant descendants. This reconfiguration aims to ensure their full participation in the nation-state’s social, cultural, and political life. By shifting the responsibility to nation-states, the article aligns with Sayad’s critique of migration policies, emphasising the need for structural reforms that transcend legal recognition to achieve genuinely inclusive practices. This approach is vital for addressing the disparities and tensions within contemporary nation-states and moving towards a more equitable society.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

New technologies can have an impact on the fundamental organizational operations, altering well established policies and procedures. New technologies have also been poorly implemented more often than not thus mitigating the opportunities they offer. The poor implementation tends to be a direct result of a lack of proper documentation of organizational processes. This improper documentation means that any system built to support the processes that is based upon the improper documentation will itself be faulty. This thesis develops the OBPM algorithm into an objected graphical modeling language and process. The Activity-based Process Modeling (ABPM) constructs have specific and well-defined semantics for real world business process representation. Further, the change propagation algorithm which is based upon a set of ontologically derived rules is refined to create a systematic process for modeling a business process. The strength of the algorithm is from its ontological real world foundations rather than programming or data design rules of thumb. This thesis also explores the relationship of ABPM and OOEM. Both languages are designed to model a specific view of organizational activity, irrespective of how a later information system artifact will be built. By relating the two grammars using ontological foundations we can acquire greater understanding of an organization without losing information. Finally, this thesis proposes a set of design principles for an ABPM CASE tool that is implementation independent which means that no matter how one decides to implement ABPM if they follow our requirements they will be able to create a tool to fully support the business process model generation process.

description: Municipal bonds have recently been of national interest and Michigan’s strained economy over the past decade has made bond issuance in the state of particular interest to a variety of stakeholders. Given the close connection between municipal bonds and property taxes, the fall-off in the housing market has placed significant strain on bonds within the state. This paper reviews the Michigan municipal bond condition and develops a new debt assessment indicator system. This system was tested using over 700 Michigan local governments. Based on this indicator system, a number of communities are experiencing significant fiscal stress. However, further examination reveals that at least some of these communities have in place short term plans to address such stress. Most importantly, the report notes that data deficiencies make it difficult to assess the true level of stress and risk in the Michigan municipal bond market.

description: O objetivo deste trabalho é testar empiricamente a hipótese ambiental de Kuznets aplicada ao relacionamento entre a taxa de desmatamento e a renda per capita nos estados da Amazônia Legal, além analisar o comportamento da taxa de desmatamento e da dinâmica populacional no período de 1990-2004. O teste econométrico utilizado para avaliar a hipótese ambiental de Kuznets é baseado na estimação de dois modelos específicos de regressão, o primeiro representa uma função quadrática e o segundo uma função cúbica, em que a taxa de desmatamento é a variável explicada, e a renda per capita, a densidade demográfica e o ano são as explicativas. Na estimação dos parâmetros utilizou-se a modelagem de dados em painel para efeitos aleatórios. Os resultados mostram que para a função quadrática original da hipótese ambiental de Kuznets apresentou resultado inverso ao esperado. Para função cúbica, a estimação da função apresenta evidência estatística de adequação aos pressupostos da curva “U” ambiental, para renda inferior a R$ 6.000,00. The objective of this study is to test the hypothesis empirically, environmental Kuznets applied to the relationship between the rate of deforestation in per capita income in the states of Amazonia Legal, besides analyzing the behavior of the rate of deforestation and population dynamics in the period of 1990-2004. The econometric test used to assess the environmental Kuznets hypothesis is based on the estimation of two specific models of regression, the first is a function quadratic and cubic according to a function, where the rate of deforestation is the variable explained, and the per capita income, the population density and the year are the explanatory. In the estimation of the parameters used to modeling data in panel for random effects. The results show that for the quadratic function of the original hypothesis of environmental Kuznets presented to the opposite result expected. For cubic function, the estimation of the function presents statistical evidence of the appropriateness of the assumptions curve "U" environmental, rent for less than $ 6.000,00.

description: Today, component oriented middlewares are used to design, develop and deploy easily distributed applications, by ensuring the heterogeneity, interoperability, and reuse of the software modules, and the separation between the business code encapsulated in the components and the system code managed by the containers. Several standards answer this definition such as: CCM (CORBA Component Model), EJB (Enterprise Java Beans) and .Net. However these standards offer a limited and fixed number of system services, removing any possibility to add system services or to reconfigure dynamically the middleware. Our works propose mechanisms to add and to adapt dynamically the system services, based on a reconfiguration language which is dynamically adaptable to the need of the reconfiguration, and on a tool of dynamic reconfiguration, a prototype was achieved for the OpenCCM platform, that is an implementation of the CCM specification. This work was partially financed by the european project IST-COACH (2001-34445).

description: O objetivo deste estudo é analisar as características da oferta de hortaliças nas micro-bacias Bandeira e Segredo com base na NEI. Para tanto foi feita uma pesquisa junto a 12 propriedades rurais. Os resultados mostram que os proprietários da bacia do Córrego Bandeira são, em sua maioria, comodatários que não consegue incentivo governamental por falta de comprovação de renda. Porém, para os proprietários da bacia do Segredo, o direito de propriedade é adquirido, mas eles não têm financiamento por falta de conhecimento ou de informações sobre crédito. Constatou-se, então, que eles têm dificuldade em obter crédito rural suficiente para suas exigências produtivas, apesar de as normas os privilegiar com juros menores e prazos maiores. The objective of this study is to analyze the characteristics of the supply of farm produce in the micro-basins Bandeira and Segredo based on the NEI. For this was a search along a 12 rural properties. The results show that the owners of the Bandeira stream flag are, in their majority, which land renter not encouraging government for lack of proof of income. But for the owners of the Segredo basins, the right to property is purchased, but they do not have funding for lack of knowledge or information on credit. It was then that they have difficulty in obtaining credit rural productive enough to their demands, despite the focus with the standards and deadlines higher interest minors.

description: Country-of-Origin Labeling (COOL) legislation for fish and shellfish was passed as part of the Farm Security and Rural Investment Act of 2002. Farm-raised and wild-caught seafood items caught after December 4, 2004, began COOL in April 4, 2005. COOL requires retailers to display the country of origin on seafood. Using a nonlinear AIDS model the demand for 3 salmon products was estimate--precooked, uncooked fresh, and uncooked frozen. COOL had no significant impact on consumer demand for the three products. The 3 salmon products were all found to be inelastic, but uncooked fresh was found to be more price sensitive than precooked and uncooked frozen salmon.

description: Nowadays, numerous component models are used for various purposes: to build applications, middleware or even operating systems. Those models commonly support structure reconfiguration, that is modification of application's architecture at runtime. On the other hand, very few allow implementation reconfiguration, that is runtime modification of the code of components building the application. In this article we present the work we performed on JULIA, a Java-based implementation of the FRACTAL component model, in order for it to support implementation reconfigurations. We show how we overcame the limitations of Java class loading mechanism to allow runtime modifications of components' implementation and interfaces. We also describe the integration of our solution with the JULIA ADL.
