Geology, alteration, lithogeochemistry and hydrothermal fluid characterization of the Neoproterozoic Niblack polymetallic volcanic-hosted massive sulfide camp, southeast Alaska, USA
Creators: name: McNulty, Brian
Publisher: name: University of British Columbia
Year: 2014

description: The Neoproterozoic Alexander terrane Niblack Cu-Au-Zn-Ag volcanic-hosted massive sulfide camp is on Prince of Wales Island, southeast Alaska. Multiple massive sulfide deposits occur at different stratigraphic levels in 565 ±1.25 Ma felsic volcanic strata. Host rocks are vent-proximal felsic pyroclastic volcanic breccia, lapilli tuff, coherent flows (Lookout deposit, Trio zone) and vent-distal felsic ash tuffs (Niblack Mine, Mammoth and Dama zones). New geochemical data and volcanic lithofacies indicate the host stratigraphy was deposited in a juvenile oceanic back-arc basin. Sub-seafloor mineralization (Lookout deposit, Trio zone) consists of 15-75% sulfide with disseminated to net-textured to semi-massive sulfide textures. These ores precipitated in unconsolidated water-laden vent-proximal felsic volcanic stratigraphy. Seafloor exhalative mineralization (Niblack Mine, Mammoth and Dama zones) is comprised of massive (>90%) poorly-banded sulfide. This type of sulfide precipitated on the paleo-seafloor in, or above, less-permeable vent-distal felsic ash tuff stratigraphy. Sub-seafloor sulfide, related hydrothermal alteration assemblages, and variations in metal ratios represent hydrothermal fluid flow and cooling through the host stratigraphy. Temperature estimates from chlorite microprobe data indicate sub-seafloor 1:1 Cu:Zn and 1:10 Au:Ag chlorite-rich alteration (Lookout deposit) formed at 321 ±19°C and seafloor exhalative 3:1 Cu:Zn and 1:10 Au:Ag magnesium-rich chlorite alteration (Niblack Mine) formed at 307 ±16°C. Sulfur, oxygen, deuterium and carbon stable isotope results are used to identify the origin of hydrothermal fluids. Sulfide mineral separates have δ³⁴S values of +6.6 to +10.5‰. Calculated fluid compositions of chlorite and sericite have values of +2.3 to +5.9‰ δ¹⁸O(water) and -24.9 to -77.1‰ δD(water). Calculated δ¹⁸O(water) values of magnetite are +8.1 to +15.5‰ and values of carbonate are -13.5 to +9.0‰ δ¹⁸O(water) and -4.4 to -0.5‰ δ¹³C(calcite). The sulfur isotope results indicate sulfur was derived from leached igneous sulfide and minor seawater sulfate reduction. The oxygen, deuterium and carbon isotopic signatures indicate evolved seawater and magmatic hydrothermal fluid sources. The Lookout deposit is the largest in the camp and has the largest magmatic fluid component. Seafloor exhalative sulfide mineralization (Niblack Mine) formed from an evolved seawater-dominant hydrothermal fluid. This suggests magmatic fluids contributed extra metals and sulfur to the hydrothermal system that enhanced the size of the Lookout deposit.

description: In a previous work, Optics Communications 284 (2011) 2460--2465, we considered a dielectric medium with an anti-reflection coating and a spatially uniform index of refraction illuminated at normal incidence by a quasimonochromatic field. Using the continuity equations for the electromagnetic energy density and the Gordon momentum density, we constructed a traceless, symmetric energy--momentum tensor for the closed system. In this work, we relax the condition of a uniform index of refraction and consider a dielectric medium with a spatially varying index of refraction that is independent of time, which essentially represents a mechanically rigid dielectric medium due to external constraints. Using continuity equations for energy density and for Gordon momentum density, we construct a symmetric energy--momentum matrix, whose four-divergence is equal to a generalized Helmholtz force density four-vector. Assuming that the energy-momentum matrix has tensor transformation properties under a symmetry group of space-time coordinate transformations, we derive the global conservation laws for the total energy, momentum, and angular momentum.

When time runs out : the experience of unintentional childlessness for women who delayed childbearing
Creators: name: Koert, Emily Christina
Publisher: name: University of British Columbia
Year: 2014

description: Given that an increasing number of women are waiting to have children there is growing concern that more women will end up unintentionally childless as they continue to delay childbearing past the time when a viable pregnancy is possible. However, little is known about the experience of permanent, unintentional childlessness for women who have delayed childbearing. This phenomenon was the focus of this study. A qualitative approach was used to answer the question: What is the meaning and experience of permanent unintentional childlessness for women who delayed childbearing? In-depth, tape recorded interviews were conducted with 15 women who had expected to become mothers but were now permanently and unintentionally childless after delaying childbearing. The interviews were transcribed, coded, and analyzed using van Manen’s (1990) hermeneutic phenomenological method. Thematic representations and rich descriptions of the experience of this phenomenon were developed. Six common themes were identified across the women’s experiences of unintentional childlessness after delay including: 1) Sense of Grief and Loss; 2) Sense of Being an Outsider in a World of Mothers; 3) Sense of Judgment and Assumptions; 4) Sense of Powerlessness; 5) Need to Make Sense of Childlessness; and 6) Sense of Reconciliation and Acceptance. Trustworthiness of the results was determined using criteria consistent with the hermeneutic phenomenological method. The findings are compared with the theoretical and extant literature, with emphasis being placed on how they extend our current understanding of the phenomenon of permanent unintentional childlessness after delay for women. The implications for Counselling Psychology practice and future research are also addressed.

description: We consider tilting mutations of a weakly symmetric algebra at a subset of simple modules, as recently introduced by T. Aihara. These mutations are defined as the endomorphism rings of certain tilting complexes of length 1. Starting from a weakly symmetric algebra A, presented by a quiver with relations, we give a detailed description of the quiver and relations of the algebra obtained by mutating at a single loopless vertex of the quiver of A. In this form the mutation procedure appears similar to, although significantly more complicated than, the mutation procedure of Derksen, Weyman and Zelevinsky for quivers with potentials. By definition, weakly symmetric algebras connected by a sequence of tilting mutations are derived equivalent, and hence stably equivalent. The second aim of this article is to study these stable equivalences via a result of Okuyama describing the images of the simple modules. As an application we answer a question of Asashiba on the derived Picard groups of a class of self-injective algebras of finite representation type. We conclude by introducing a mutation procedure for maximal systems of orthogonal bricks in a triangulated category, which is motivated by the effect that a tilting mutation has on the set of simple modules in the stable category.

description: The hardness of fitness functions is an important research topic in the field of evolutionary computation. In theory, the study can help understanding the ability of evolutionary algorithms. In practice, the study may provide a guideline to the design of benchmarks. The aim of this paper is to answer the following research questions: Given a fitness function class, which functions are the easiest with respect to an evolutionary algorithm? Which are the hardest? How are these functions constructed? The paper provides theoretical answers to these questions. The easiest and hardest fitness functions are constructed for an elitist (1+1) evolutionary algorithm to maximise a class of fitness functions with the same optima. It is demonstrated that the unimodal functions are the easiest and deceptive functions are the hardest in terms of the time-fitness landscape. The paper also reveals that the easiest fitness function to one algorithm may become the hardest to another algorithm, and vice versa.

description: For every integer d > 9, we construct infinite families {G_n}_n of d+1-regular graphs which have a large girth > log_d |G_n|, and for d large enough > 1,33 log_d |G_n|. These are Cayley graphs on PGL_2(q) for a special set of d+1 generators whose choice is related to the arithmetic of integral quaternions. These graphs are inspired by the Ramanujan graphs of Lubotzky-Philips-Sarnak and Margulis, with which they coincide when d is prime. When d is not equal to the power of an odd prime, this improves the previous construction of Imrich in 1984 where he obtained infinite families {I_n}_n of d+1-regular graphs, realized as Cayley graphs on SL_2(q), and which are displaying a girth > 0,48 log_d |I_n|. And when d is equal to a power of 2, this improves a construction by Morgenstern in 1994 where certain families {M_n}_n of 2^k+1-regular graphs were shown to have a girth > 2/3 log_d |M_n|.

description: Cryo-electron microscopy (cryo-EM) has recently emerged as a powerful tool for obtaining three-dimensional (3D) structures of biological macromolecules in native states. A minimum cryo-EM image data set for deriving a meaningful reconstruction is comprised of thousands of randomly orientated projections of identical particles photographed with a small number of electrons. The computation of 3D structure from 2D projections requires clustering, which aims to enhance the signal to noise ratio in each view by grouping similarly oriented images. Nevertheless, the prevailing clustering techniques are often compromised by three characteristics of cryo-EM data: high noise content, high dimensionality and large number of clusters. Moreover, since clustering requires registering images of similar orientation into the same pixel coordinates by 2D alignment, it is desired that the clustering algorithm can label misaligned images as outliers. Herein, we introduce a clustering algorithm $γ$-SUP to model the data with a $q$-Gaussian mixture and adopt the minimum $γ$-divergence for estimation, and then use a self-updating procedure to obtain the numerical solution. We apply $γ$-SUP to the cryo-EM images of two benchmark macromolecules, RNA polymerase II and ribosome. In the former case, simulated images were chosen to decouple clustering from alignment to demonstrate $γ$-SUP is more robust to misalignment outliers than the existing clustering methods used in the cryo-EM community. In the latter case, the clustering of real cryo-EM data by our $γ$-SUP method eliminates noise in many views to reveal true structure features of ribosome at the projection level.

description: We present density functional theory calculations of the geometry, adsorption energy and electronic structure of thiophene adsorbed on Cu(111), Cu(110) and Cu(100) surfaces. Our calculations employ dispersion corrections and self-consistent van der Waals density functionals (vdW-DFs). In terms of speed and accuracy, we find that the dispersion-energy-corrected Revised Perdue-Burke-Enzerhof (RPBE) functional is the "best balanced" method for predicting structural and energetic properties, while vdW-DF is also highly accurate if a proper exchange functional is used. Discrepancies between theory and experiment in molecular geometry can be solved by considering x-ray generated core-holes. However, the discrepancy concerning the adsorption site for thiophene/Cu(100) remains unresolved and requires both further experiments and deeper theoretical analysis. For all the interfaces, the PBE functional reveals a covalent bonding picture which the inclusion of dispersive contributions does not change to a vdW one. Our results provide a comprehensive understanding of the role of dispersive forces in modelling molecule-metal interfaces.

In the case of quasi-elementary groups the description is intricate, and it does not specify groups that have primitive relations in terms of generators and relations. In this paper we do this for quasi-elementary groups of order p^aq.

description: Physical ageing phenomena far from equilibrium naturally lead to dynamical scaling. It has been proposed to consider the consequences of an extension to a larger Lie algebra of local scale-transformation. The best-tested applications of this are explicitly computed co-variant two-point functions which have been compared to non-equilibrium response functions in a large variety of statistical mechanics models. It is shown that the extension of the Schrödinger Lie algebra $\mathfrak{sch}(1)$ to a maximal parabolic sub-algebra, when combined with a dualisation approach, is sufficient to derive the causality condition required for the interpretation of a two-point function as a physical response function. The proof is presented for the recent logarithmic extension of the differential operator representation of the Schrödinger algebra.

description: We show that the double diffractive electroweak vector boson production in the $pp$ collisions at the LHC is an ideal probe of QCD based mechanisms of diffraction. Assuming the resolved Pomeron model with flavor symmetric parton distributions, the $W$ production asymmetry in rapidity equals exactly zero. In other approaches, like the soft color interaction model, in which soft gluon exchanges are responsible for diffraction, the asymmetry is non-zero and equal to that in the inclusive $W$ production. In the same way, the ratio of the $W$ to $Z$ boson production is independent of rapidity in the models with resolved Pomeron in contrast to the predictions of the soft color interaction model.

description: The vehicle-to-vehicle (V2V) propagation channel has significant implications on the design and performance of novel communication protocols for vehicular ad hoc networks (VANETs). Extensive research efforts have been made to develop V2V channel models to be implemented in advanced VANET system simulators for performance evaluation. The impact of shadowing caused by other vehicles has, however, largely been neglected in most of the models, as well as in the system simulations. In this paper we present a shadow fading model targeting system simulations based on real measurements performed in urban and highway scenarios. The measurement data is separated into three categories, line-of-sight (LOS), obstructed line-of-sight (OLOS) by vehicles, and non line-of-sight due to buildings, with the help of video information recorded during the measurements. It is observed that vehicles obstructing the LOS induce an additional average attenuation of about 10 dB in the received signal power. An approach to incorporate the LOS/OLOS model into existing VANET simulators is also provided. Finally, system level VANET simulation results are presented, showing the difference between the LOS/OLOS model and a channel model based on Nakagami-m fading.

description: Nella grandiosa elaborazione di "L'Essence de la manifestation" (1965), Michel Henry ha di fatto definitivamente posto in evidenza i princìpi fondamentali della sua "phénoménologie de la vie". In ragione della sua radicale "critica della trascendenza" - non senza un decisivo contrasto con le analisi heideggeriane di "Sein und Zeit" - Henry ha da sempre rivendicato e difeso l'irriducibile eterogeneità della "verità originaria" rispetto alla ek-staticità del mondo. Questo studio offre una ricostruzione "dall'interno" del percorso teoretico compiuto da Michel Henry: criticamente segue lo sviluppo argomentativo di "L'Essence de la manifestation" per mezzo del quale sono determinati i caratteri fenomenologici costitutivi dell'"apparire originario" (immanenza, invisibilità, affettività). In forza di un serrato confronto con le fonti teoretiche (tra cui Husserl, Heidegger, Fichte, Meister Eckhart) che variamente hanno ispirato il filosofo francese, il saggio mira a porre in evidenza la specificità della fenomenologia henryana. Ma dove Henry si tiene strettamente, irrinunciabilmente legato ai temi puramente fenomenologici, il volume punta a condurre ancor oltre la sua interrogazione, ponendo la più ampia questione della "fondazione (non ontica) del pensiero filosofico". La lettura del testo henryano apre allora alla possibilità di un rinnovato confronto con i temi della "prima philosophia"

description: The concept of competitiveness, for a long time considered as strictly connected to economic and financial performances, evolved, above all in recent years, toward new, wider interpretations disclosing its multidimensional nature. The shift to a multidimensional view of the phenomenon has excited an intense debate involving theoretical reflections on the features characterizing it, as well as methodological considerations on its assessment and measurement. The present research has a twofold objective: going in depth with the study of tangible and intangible aspect characterizing multidimensional competitive phenomena by assuming a micro-level point of view, and measuring competitiveness through a model-based approach. Specifically, we propose a non-parametric approach to Structural Equation Models techniques for the computation of multidimensional composite measures. Structural Equation Models tools will be used for the development of the empirical application on the Italian case: a model based micro-level competitiveness indicator for the measurement of the phenomenon on a large sample of Italian small and medium enterprises will be constructed.

description: The debate on tobacco taxes and fat taxes often treats smoking and eating as independent behaviors. However, since there exists medical and sociological evidence about
the interdependence between eating and smoking choices, antismoking policies may also affect the obesity prevalence and fat taxes could influence smoking behavior. We address
this issue from a theoretical standpoint and propose a dynamic rational model where eating and smoking are simultaneous choices that jointly affect body weight and addiction to smoking. Focusing on direct and cross price effects, we compare tobacco taxes and fat taxes and we show that a single policy tool can reduce both smoking and body weight. In particular, fat taxes can be more effective than tobacco taxes at simultaneously fighting obesity and smoking.

description: For the class of differentiable maps of the plane and, in particular, for standard-like maps (McMillan form), a simple relation is shown between the directions of the local invariant manifolds of a generic point and its contribution to the finite-time Lyapunov exponents (FTLE) of the associated orbit. By computing also the point-wise curvature of the manifolds, we produce a comparative study between local Lyapunov exponent, manifold's curvature and splitting angle between stable/unstable manifolds. Interestingly, the analysis of the Chirikov-Taylor standard map suggests that the positive contributions to the FTLE average mostly come from points of the orbit where the structure of the manifolds is locally hyperbolic: where the manifolds are flat and transversal, the one-step exponent is predominantly positive and large; this behaviour is intended in a purely statistical sense, since it exhibits large deviations. Such phenomenon can be understood by analytic arguments which, as a by-product, also suggest an explicit way to point-wise approximate the splitting.

Subjects: SECS-P/01 Economia politica

description: This paper employs a recent statistical algorithm (CRAGGING) in order to build an early warning model for banking crises in emerging markets. We perturb our data set many times and create “artificial” samples from which we estimated our model, so that, by construction, it is flexible enough to be applied to new data for out-of-sample prediction. We find that, out of a large number (540) of candidate explanatory variables, from macroeconomic to balance sheet indicators of the countries’ financial sector, we can accurately predict banking crises by just a handful of variables. Using data over the period from 1980 to 2010, the model identifies two basic types of banking crises in emerging markets: a “Latin American type”, resulting from the combination of a (past) credit boom, a flight from domestic assets, and high levels of interest rates on deposits; and an “Asian type”, which is characterized by an investment boom financed by banks’ foreign debt. We compare our model to other models obtained using more traditional techniques, a Stepwise Logit, a Classification Tree, and an “Average” model, and we find that our model strongly dominates the others in terms of out-of-sample predictive power.
Thermal mechanical analysis of interfacial behavior in aluminum alloy wheel casting process
Creators: name: Wei, Xiaodan
Publisher: name: University of British Columbia
Year: 2014

description: The focus of this project is to improve the understanding of the interfacial heat transfer behavior within the Low-Pressure Die Casting (LPDC) process, which is the main manufacturing process for A356 aluminum alloy wheels, and to develop an improved methodology/expression for calculating the heat transfer across the wheel/die interface. To formulate and assess expressions for the interfacial behavior, a 2D-axisymmetric coupled thermo-mechanical model has been developed in the commercial finite element package, ABAQUS. The model was capable of predicting the thermal history, deformation and the variation of the air gap and pressure along the wheel/die interface. The temperature predictions of the coupled thermo-mechanical model were compared with temperature measurements obtained at Canadian Auto Parts Toyota Inc obtained on a production die. A displacement measurement setup using a high temperature eddy current displacement sensor was designed and tested in a lab setting but not employed in a plant trial due timing issues. Initially, the coupled thermo-mechanical model was run with a temperature dependent interfacial heat transfer coefficient to obtain preliminary air gap and pressure behavior at various locations. Comparisons with the thermocouple measurements suggest that the model is able to generally qualitatively, and at some locations quantitatively, predict the temperature changes from the main physical phenomena occurring during the casting process. The preliminary air gap and pressure predictions were used to develop a temperature, gap size and pressure dependent interfacial heat transfer coefficient based on literature review. The interfacial heat transfer coefficient was implemented in the model, and was found to improve the agreement between the model predictions and measured temperatures, but was prone to numerical convergence issues. A new methodology of incrementally changing the interfacial heat transfer coefficient has been proposed to solve the issues. The methodology was implemented in an EXCEL spreadsheet to test it and the calculated interfacial heat transfer coefficients were found to be continuous, reflecting the effects of air gap and pressure evolution. The methodology and corresponding algorithm should be further developed for use in an ABAQUS model in the future.

description: Neuroprotection under conditions of oxygen stress of two C21 steroidal glycosides, cynsaccatol Q (1) and saccatol K (2), isolated from Cynanchum auriculatum Royle ex Wight, and their potential mechanisms were studied using the model of H2O2-induced damage on PC12 cells in this paper. Experiments showed that compounds 1 and 2 can both regulate the activities of antioxidant enzymes, including GSH-Px, LDH, CAT, SOD, decrease the levels of intracellular ROS and Ca2+, reduce cell apoptosis, and regulate the expression of HO-1 and NQO1 through the Nrf2-ARE pathway, thus play the role of neuroprotection against oxidative damage.

description: The European power grid can be divided into several market areas where the price of electricity is determined in a day-ahead auction. Market participants can provide continuous hourly bid curves and combinatorial bids with associated quantities given the prices. The goal of our auction is to maximize the economic surplus of all participants subject to quantity constraints and price constraints. The price constraints ensure that no one incurs a loss. Only traders who submitted a combinatorial bid might miss a not-realized profit. The resulting problem is a large scale mathematical program with equilibrium constraints (MPEC) and binary variables that cannot be solved efficiently by standard solvers. We present an exact algorithm and a fast heuristic for this type of problem. Both algorithms decompose the MPEC into a master problem (a MIQP) and pricing subproblems (LPs). The modeling technique and the algorithms are applicable to a wide variety of combinatorial auctions that are based on mixed integer programs.

Understanding teacher well-being and motivation : measurement, theory, and change over time
Creators: name: Collie, Rebecca J
Publisher: name: University of British Columbia

description: Teacher well-being and motivation play important roles in teacher and student experiences at school. When teachers are faring well and feeling motivated to teach, they are more effective in their teaching, leave the profession less often, and promote motivation and achievement among their students. In this dissertation, three studies that investigated teacher well-being and motivation were conducted with the aim of advancing our understanding of the two constructs, as well as how they can be promoted among teachers. Study 1 involved conceptualising, developing, and testing the Teacher Well-Being Scale, which measures three factors of teacher well-being: workload well-being, organisational well-being, and student interaction well-being. Among a sample of 603 practicing teachers, results revealed that the new measure functioned similarly across the different demographic groups in the sample and that the three factors of well-being related as expected with other constructs (stress, job satisfaction, and flourishing). Study 2 involved elaborating and testing an explanatory model of teacher well-being, motivation, job satisfaction, and affective organisational commitment that was based in self-determination theory (Deci & Ryan, 1985, 2002). Using the same sample as Study 1, structural equation modelling provided support for the model’s main relationships. In addition, there were some unexpected findings that provide directions for future research (e.g., a double-sided view of autonomy revealing that it can be associated with positive and negative types of motivation). Study 3 involved examining growth curve models of change in teacher well-being and self-efficacy for teaching over two to three months. Among a sample of 71 practicing teachers, the findings showed that teacher well-being was stable over time, whereas self-efficacy for classroom management increased (the other two types of self-efficacy that were examined, self-efficacy for student engagement and instructional strategies, did not change over time). Findings also revealed the significance of the basic psychological needs (autonomy, competence, and relatedness) in predicting teacher well-being and self-efficacy. Taken together, the three studies help to improve our understanding of the highly important variables of teacher well-being and motivation. Implications of the findings for both research and practice are discussed.

Dynamics of Investment and Firm Performance: Comparative evidence from manufacturing industries

description: If the relation between investment and economic growth is well established in the macroeconomic literature, the existence of a similar link at the level of the firm has been challenged by empirical work. This paper investigates the channels linking investment and firm performance in the French and Italian manufacturing industries. It does so by putting forth a novel methodology to identify investment spikes that corrects for size dependence. While maintaining the desired properties of a spike measure, our chosen proxy retrieves the expected relation between investment and firm performance. Ex-ante, more efficient and fast growing firms display a higher probability to invest; in turn, after an investment spike has taken place the group of investing firms shows further gains in performance. Finally, expansionary investment episodes, as proxied by the opening of new plants, have a negative effect on profitability while they are associated with higher sales and employment levels.

description: Abstract
 Technologies not only extend capabilities but also mediate experience and action. To date, however, research on technology-facilitated violence has tended not to focus on the role technological mediation plays in acts of violence facilitated through technology. Building on prior work in the field, this article develops a theoretical framework and typology for understanding the role technological mediation plays in producing technology-facilitated violence. First, drawing on postphenomenological theories of technology, we argue that technology-facilitated violence is best understood as a form of ‘harm translation,’ where a technology’s affordances and other properties ‘invite’ an individual to actualize harmful ends. Then, distinguishing between four modes of harm translation, we construct a typology for analysing the intersections between user intention and technological design that, together, facilitate violence. We argue that by attending to these distinctions our typology may help researchers and designers identify and address the specific causal dynamics involved in producing different kinds of technology-facilitated harm.
A Semi-analytical Solution to Classic Yang-Mills Equations with Both Asymptotical Freedom and Confining Features

description: It is well known that confinings and asymptotic freedom are properties of quantum chromo-dynamics (QCD). But hints of these features can also be observed at purely classic levels. For this purpose we need to find solutions to the colorly-sourceful Yang-Mills equations with both confining and asymptotic freedom features. We provide such a solution in this paper which at the near-source region is of serial form, while at the far-away region is approximately expressed through simple elementary functions. From the solution, we derive out a classically non-perturbative beta function describing the running of effective coupling constant, which is linear in the couplings both in the infrared and ultraviolet region.

Cumulative Causation at Work: Intergenerational Transfers and Social Capital in a Spatially Varied Economy

description: This paper models the dynamic of migration with a particular focus on the cumulative process that causes a variation in the distribution of income in sending communities and therefore a variation in the distribution of skills across different cohorts. The model provides a theoretical framework to Cumulative Causation theory of migration and specifically a theoretical rationale behind the use of migration prevalence ratio to study migration flows. Moreover the model shows how brain drain (in sending communities) and negative cohort effect in terms of education (in receiving communities) are the result of a positive selection of migrants in terms of skills if there is a intergenerational transmission of education.

description: We establish a Penrose-Ward transform yielding a bijection between holomorphic principal 2-bundles over a twistor space and non-Abelian self-dual tensor fields on six-dimensional flat space-time. Extending the twistor space to supertwistor space, we derive sets of manifestly N=(1,0) and N=(2,0) supersymmetric non-Abelian constraint equations containing the tensor multiplet. We also demonstrate how this construction leads to constraint equations for non-Abelian supersymmetric self-dual strings.
