description: This study examines the performance of stable cooperative coalitions that form to provide a public good when coalition members have the opportunity to not comply with their commitments. A stable coalition is one in which no member wishes to leave and no non-member wishes to join. To counteract the incentive to violate their commitments, coalition members fund a third-party enforcer. This leads to the theoretical conclusion that stable coalitions are larger (and provide more of a public good) when their members must finance enforcement relative to when compliance is ensured without the need for costly enforcement. However, our experiments reveal that giving coalition members the opportunity to violate their commitments while requiring them to finance enforcement to maintain compliance reduces the overall provision of the public good. The decrease in the provision of the public good is attributed to an increase in the participation threshold for a theoretically stable coalition to form and to significant levels of noncompliance. When we abandon the strict stability conditions and require all subjects to join a coalition for it to form, the average provision of the public good increases significantly.

description: We demonstrate dynamical nuclear spin polarization in the absence of an external magnetic field, by resonant circularly polarized optical excitation of a single electron or hole charged quantum dot. Optical pumping of the electron spin induces an effective inhomogeneous magnetic (Knight) field that determines the direction along which nuclear spins could polarize and enables nuclear-spin cooling by suppressing depolarization induced by nuclear dipole-dipole interactions. Our observations suggest a new mechanism for spin-polarization where spin exchange with an electron reservoir plays a crucial role. These experiments constitute a first step towards quantum measurement of the Overhauser field.

description: Under favorable but reasonable conditions, an imperfectly enforced emissions tax produces the efficient allocation of individual emissions control; aggregate emissions are independent of whether enforcement of the tax is sufficient to induce the full compliance of firms, and differences in individual violations are independent of firm-level differences. All of these desirable characteristics disappear when some firms under an emissions tax risk bankruptcy—the allocation of emissions control is inefficient, imperfect enforcement causes higher aggregate emissions, and financially insecure firms choose higher violations.

description: In this paper we describe a field experiment conducted among mollusk harvesters in a community on the Pacific Coast of Columbia. The experiment is based on a standard linear public good and consists of two stages. In the first stage we compare the ability of monetary and nonmonetary sanctions among community members to increase contributions to the public good. In the second stage we add a government regulation with either a high or low sanction for noncompliance to community enforcement efforts. The results for the first stage are consistent with other comparisons of monetary and nonmonetary sanctions within groups; both led to higher contributions. The results from the second stage reveal that government regulations always complemented community enforcement efforts. While the subjects tended to reduce their sanctioning efforts under the government regulations, contributions and earnings were significantly higher than without government interventions. In fact, the combination of community and government enforcement efforts generated near-perfect contributions to the public good. However, more research into the combined roles of government intervention and community enforcement efforts is needed because the complementarity we find may be situation-specific.

description: The mechanisms responsible for the production of relativistic jets from supermassive black holes (SMBHs) accreting at near-Eddington rates are not well-understood. Simple theoretical expectations indicate that SMBHs in quasars accrete via thin discs which should produce at most very weak jets. This is contradicted by observations of powerful jets in flat-spectrum radio quasars (FSRQs). We use gamma-ray luminosities observed with the \emph{fermi} Large Area Telescope as a proxy of the jet power for a population of 154 FSRQs. Assuming typical quasar accretion rates and using black hole mass measurements from a variety of methods, we find a mean jet production efficiency of about 10 per cent for FSRQs, with values as high as 222 per cent. We find that this is consistent with FSRQs hosting moderately thin, magnetically arrested accretion discs around rapidly spinning black holes (BHs). Modeling our observations using general relativistic magnetohydrodynamic (GRMHD) simulations of jets from thin discs, we find an average lower limit of $a_* = 0.59$ for the SMBH spins of FSRQs, with tendency for the spins to decrease as the black hole mass increases. Our results are consistent with the merger-driven evolution of SMBHs. 3 per cent of the sample cannot be explained by current GRMHD models of jet production from Kerr BHs due to the high efficiencies. Along the way, we find a correlation between BH masses and $L_γ$ which may be an useful mass estimator in blazar gamma-ray studies.

description: In contrast with what we perceive is the conventional wisdom about setting emissions taxes under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes will deviate from expected marginal damage if there is uncertainty about the slopes of the marginal abatement costs of regulated firms. Moreover, efficient emissions tax rates will vary across firms if a regulator can use observable firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary.
Relation between Statics and Dynamics in the Quench of the Ising Model to below the Critical Point

description: The standard phase-ordering process is obtained by quenching a system, like the Ising model, to below the critical point. This is usually done with periodic boundary conditions to insure ergodicity breaking in the low temperature phase. With this arrangement the infinite system is known to remain permanently out of equilibrium, i.e. there exists a well defined asymptotic state which is time-invariant but different from the ordered ferromagnetic state. In this paper we establish the critical nature of this invariant state, by demonstrating numerically that the quench dynamics with periodic and antiperiodic boundary conditions are indistinguishable one from the other. However while the asymptotic state does not coincide with the equilibrium state for the periodic case, it coincides instead with the equilibrium state of the antiperiodic case, which in fact is critical. The specific example of the Ising model is shown to be one instance of a more general phenomenon, since an analogous picture emerges in the spherical model, where boundary conditions are kept fixed to periodic, while the breaking or preserving of ergodicity is managed by imposing the spherical constraint either sharply or smoothly.

The Building Blocks of Human Capital: Socioculturalism and Career Development of Maltese Youths

Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: The aim of this study is to identify socio-cultural factors that are influencing career development, and their role in the career development process of Maltese youths. Career development is about planning one’s career meticulously, which ultimately does not only benefit the individual, but also the country’s human capital. Given that the sense of community and culture amongst the Maltese population is still very strong, one can expect that youths can be influenced by socio-cultural factors during their course of career development. The contribution to knowledge of this study is mainly towards local career development research in relation to human capital. The main research question is How are socio-cultural factors influencing the career developmental process during youthhood? There were three cohorts who participated in this research: younger youths aged 14 to 18 years, emerging adults aged 19 to 25 years, and adult professionals and parents. A convergent mixed methods research design was adopted, using a bespoke survey tool for quantitative methods, and semi-structured interviews for the qualitative methods. The data collection tools were designed on the components found in the Systems Theory Framework of Career Development (STF) by Patton and McMahon (1995; 2006a). The quantitative data was analysed through Principal Component Analysis (PCA), whilst the qualitative data was analysed through Grounded Theory Methodology (GTM) and Thematic Analysis (TA). The mixed methods data analysis revealed the most influential socio-cultural factors, which were categorised under six core categories. The core categories Ambition, Inspiration, Action, Implementation, Support and Barriers can be considered as phases in the youth career development process, and the Socio-culturalism of Youth Career Development model (SC-TCD) was proposed. The implications of the proposed model were related to the quality and effectiveness of career guidance and development, through refined techniques and approaches, involving the family, the community, the school, and the workplace.
Multipartite Optimized Correlation Measures and Holography

description: We explore ways to quantify multipartite correlations, in quantum information and in holography. We focus on optimized correlation measures, linear combinations of entropies minimized over all possible purifications of a state that satisfy monotonicity conditions. These contain far more information about correlations than entanglement entropy alone. We present a procedure to derive such quantities, and construct a menagerie of symmetric optimized correlation measures on three parties. These include tripartite generalizations of the entanglement of purification, the squashed entanglement, and the recently introduced Q-correlation and R-correlation. Some correlation measures vanish only on product states, and thus quantify both classical and quantum correlations; others vanish on any separable state, capturing quantum correlations alone. We then use a procedure motivated by the surface-state correspondence to construct holographic duals for the correlation measures as linear combinations of bulk surfaces. The geometry of the surfaces can preserve, partially break, or fully break the symmetry of the correlation measure. The optimal purification is encoded in the locations of certain points, whose locations are fixed by constraints on the areas of combinations of surfaces. This gives a new concrete connection between information theoretic quantities evaluated on a boundary state and detailed geometric properties of its dual.

Some special cases of this generalized bootstrap are the classical bootstrap of Efron, the delete-d jackknife and variations of the Bayesian bootstrap. The use of the proposed technique is discussed in some examples. Distributional consistency of the method is established and an asymptotic representation of the resampling variance estimator is obtained.

Industrial ecology at the Big Bend
Creators: name: Spiegelman, Jonah Z.
Publisher: name: University of British Columbia
Year: 2009

description: Metropolitan areas around the world face serious choices about the manner in which development should proceed. The widely agreed upon goal of sustainable development has yet to truly reconcile the desire for industrial development with the need for ecological integrity. Industrial ecology (IE) is a framework that aims to mitigate the environmental impacts of industrial development through the integration of industrial processes to maximize resource productivity and minimize pollution emission. Invoking an ecological metaphor, IE describes 'industrial ecosystems' that minimize their flows of material and energy, optimize their design configuration, and exploit the positive behavioral interactions among their constituents. This thesis reviews the industrial ecology literature and takes it further by linking IE with the theory of complex thermodynamic systems in an attempt to deepen the metaphor upon which it rests. If industrial systems are to be modeled after ecological systems, what characteristics of ecosystems should be emulated, and upon what basis does this assertion lie? The answers to these questions constitute my contribution to IE theory, highlight the crucial role of context that remains underemphasized in the literature, and strengthen the overall legitimacy of the framework. This enhanced theory is then applied to an industrial system in Burnaby, BC, at the center of which is a solid waste incinerator. Guided by the IE framework, I gathered data regarding the material and energy flows through the industrial system. This case study demonstrates some characteristics of an eco-industrial system, though the level of integration is generally quite low. The performance of the site is evaluated, and areas of potential improvement are identified. The result is a set of recommendations to facilitate the development of the site into a more fully integrated eco-industrial park that would positively affect the sustainability of the region.

description: The Information Retrieval research has used semantics to provide accurate search results, but the analysis of conceptual abstraction has mainly focused on information integration. We consider session-based query expansion in Geographical Information Retrieval, and investigate the impact of semantic granularity (i.e., specificity of concepts representation) on the suggestion of relevant types of information to search for. We study how different levels of detail in knowledge representation influence the capability of guiding the user in the exploration of a complex information space. A comparative analysis of the performance of a query expansion model, using three spatial ontologies defined at different semantic granularity levels, reveals that a fine-grained representation enhances recall. However, precision depends on how closely the ontologies match the way people conceptualize and verbally describe the geographic space.

description: High-resolution simulations within the GOY shell model are used to study various scaling relations for turbulence. A power-law relation between the second-order intermittency correction and the crossover from the inertial to the dissipation range is confirmed. Evidence is found for the intermediate viscous dissipation range proposed by Frisch and Vergassola. It is emphasized that insufficient dissipation-range resolution systematically drives the energy spectrum towards statistical-mechanical equipartition. In fully resolved simulations the inertial-range scaling exponents depend on both model parameters; in particular, there is no evidence that the conservation of a helicity-like quantity leads to universal exponents.

description: Food product attributes related to geographical origins are a topical issue in global food trade. The provision of geographical labelling may occur through geographical indications under the mandated trade rules of the TRIPS Agreement, trademarks, or country-of-origin labelling. The overall effect of the expansion of geographical labelling on developing countries depends on a complex mix of market opportunities that may yield substantial benefits as well as implementation costs. Increasingly, the analysis of this overall effect will need to evaluate the joint impacts of different forms of geographical labelling on the market position of developing countries.

description: We present an analysis of the thin layer of Galactic warm ionized gas at an angular resolution ~ 10'. This is carried out using radio continuum data at 1.4 GHz, 2.7 GHz and 5 GHz in the coordinate region 20 < l < 30 deg, -1.5 < b < +1.5 deg. For this purpose, we evaluate the zero level of the 2.7 and 5 GHz surveys using auxiliary data at 2.3 GHz and 408 MHz. The derived zero level corrections are T_{zero}(2.7 GHz)=0.15 +/- 0.06 K and T_{zero}(5 GHz)=0.1 +/- 0.05 K. We separate the thermal (free-free) and non-thermal (synchrotron) component by means of a spectral analysis performed adopting an antenna temperature spectral index -2.1 for the free-free emission, a realistic spatial distribution of indices for the synchrotron radiation and by fitting, pixel-by-pixel, the Galactic spectral index. We find that at 5 GHz, for |b| = 0 deg, the fraction of thermal emission reaches a maximum value of 82%, while at 1.4 GHz, the corresponding value is 68%. In addition, for the thermal emission, the analysis indicates a dominant contribution of the diffuse component relative to the source component associated with discrete HII regions.

description: A pressing need in the area of food safety is a tool for making overall, macro judgments about which risks should be given priority for management. Governments often seek to base this prioritization on public health impacts only to find that other considerations also influence the prioritization process. A multi-factorial approach formally recognizes that public health, market-level impacts, consumer risk preferences and acceptance, and the social sensitivity of particular risks all play a role in prioritization. It also provides decision makers with a variety of information outputs that allow risk prioritization to be considered along different dimensions. Macro-level prioritization of risks based on multiple factors is an important expanded use of cost-benefit analysis to manage risk.

description: We report a simultaneous 44 and 95 GHz class I methanol maser survey toward 144 sources from the 95 GHz class I methanol maser catalog. The observations were made with the three telescopes of the Korean very long baseline interferometry network operating in single-dish mode. The detection rates are 89% at 44 GHz and 77% at 95 GHz. There are 106 new discoveries at 44 GHz. Comparing the previous 95 GHz detections with new observations of the same transitions made using the Purple Mountain Observatory 13.7 m radio telescope shows no clear evidence of variability on a timescale of six years. Emission from the 44 and 95 GHz transitions shows strong correlations in peak velocity, peak flux density, and integrated flux density, indicating that they are likely cospatial. We found that the peak flux density ratio Spk,95/Spk,44 decreases as the 44 GHz peak flux density increases. We found that some class I methanol masers in our sample could be associated with infrared dark clouds, while others are associated with H II regions, indicating that some sources occur at an early stage of high-mass star formation, while others are located toward more evolved sources.

description: Many low-income people, especially those from poor rural areas, seek to improve their lives by immigrating in search of work and income, increasingly moving across national borders and further afield. In recent years, the remittances they earn have come to have an important effect on the economies of many developing countries, profoundly affecting poverty, income distribution, and rural economic development in the villages from which the migrated. The results of this study compliment the findings of other IFPRI studies on poverty alleviation, income sources, and rural development. The study uses primary household data from small area of rural Egypt in a innovative way to address such vital questions as who immigrates, how remittances affect poverty and income inequality in the receiving villages, and how spending by returning immigrants facilitates local development. The finding of this study that the rural poor, who actively participate in international migration, tend to invest their remittance earning rather than spending on own or family consumption has broad implications for policy planning of countries that send many migrants abroad.

description: This report presents the results from a study of four countries. Information was collected on Belgium, the United Kingdom, Germany and Denmark, and interviews were also held in those countries, to obtain an insight into their policies and implementation of controls on feed and food safety. The study was requested by the Ministry of Agriculture, Nature and Food Quality to prepare for the implementation of EC Regulation 882/2004 in 2006 and to provide support for the reform of the funding system for the Dutch Food and Non-Food Authority (VWA). The study focused on a search for good practices for the reform of the VWA's funding system. In opdracht van het Ministerie van LNV worden in deze publicatie bouwstenen gegeven voor de herziening van het financieringsstelsel van de VWA, ingegeven door de aanko-mende implementatie van Verordening EG 882/2004. In dit rapport wordt ingegaan op de controle-activiteiten op het gebied van voedsel en voer die voor een herziening in de kos-tentoekenning in aanmerking komen en op mogelijke opties van herziening opgedaan uit ervaringen in de ons omringende landen en bij andere inspectiediensten in Nederland. Drie scenario's van verantwoordelijkheidsverdelingen zijn afsluitend geanalyseerd op budgettai-re consequenties.

description: The main result of this paper is that a Lorentzian manifold is locally conformally equivalent to a manifold with recurrent lightlike vector field and totally isotropic Ricci tensor if and only if its conformal tractor holonomy admits a 2-dimensional totally isotropic invariant subspace. Furthermore, for semi-Riemannian manifolds of arbitrary signature we prove that the conformal holonomy algebra of a $C$-space is a Berger algebra. For Ricci-flat spaces we show how the conformal holonomy can be obtained by the holonomy of the ambient metric and get results for Riemannian manifolds and plane waves.

description: In this paper, we address the problem of using sentiment analysis tools 'off-the-shelf,' that is when a gold standard is not available for retraining. We evaluate the performance of four SE-specific tools in a cross-platform setting, i.e., on a test set collected from data sources different from the one used for training. We find that (i) the lexicon-based tools outperform the supervised approaches retrained in a cross-platform setting and (ii) retraining can be beneficial in within-platform settings in the presence of robust gold standard datasets, even using a minimal training set. Based on our empirical findings, we derive guidelines for reliable use of sentiment analysis tools in software engineering.

Eruption of a Kink-Unstable Filament in Active Region NOAA 10696

description: We present rapid-cadence Transition Region And Coronal Explorer (TRACE) observations which show evidence of a filament eruption from active region NOAA 10696, accompanied by an X2.5 flare, on 2004 November 10. The eruptive filament, which manifests as a fast coronal mass ejection some minutes later, rises as a kinking structure with an apparently exponential growth of height within TRACE's field of view. We compare the characteristics of this filament eruption with MHD numerical simulations of a kink-unstable magnetic flux rope, finding excellent qualitative agreement. We suggest that, while tether weakening by breakout-like quadrupolar reconnection may be the release mechanism for the previously confined flux rope, the driver of the expansion is most likely the MHD helical kink instability.

description: Quantum embedding theories provide a feasible route for obtaining quantitative descriptions of correlated materials. However, a critical challenge is solving an effective impurity model of correlated orbitals embedded in an electron bath. Many advanced impurity solvers require the approximation of a bath continuum using a finite number of bath levels, producing a highly nonconvex, ill-conditioned inverse problem. To address this drawback, this study proposes an efficient fitting algorithm for matrix-valued hybridization functions based on a data-science approach, sparse modeling, and a compact representation of Matsubara Green's functions. The efficiency of the proposed method is demonstrated by fitting random hybridization functions with large off-diagonal elements as well as those of a 20-orbital impurity model for a high-Tc compound, LaAsFeO, at low temperatures (T). The results set quantitative goals for the future development of impurity solvers toward quantum embedding simulations of complex correlated materials.

The Element Abundances in Bare Planetary Nebula Central Stars and the Shell Burning in AGB Stars

description: We review the observed properties of extremely hot hydrogen-deficient post-AGB stars of spectral type [WC] and PG1159. Their H-deficiency is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse, laying bare interior stellar regions which are usually kept hidden below the hydrogen envelope. Thus, the photospheric element abundances of these stars allow to draw conclusions about details of nuclear burning and mixing processes in the precursor AGB stars. We summarize the state-of-the-art of stellar evolution models which simulate AGB evolution and the occurrence of a late He-shell flash. We compare predicted element abundances to those determined by quantitative spectral analyses performed with advanced non-LTE model atmospheres. A good qualitative and quantitative agreement is found. Future work can contribute to an even more complete picture of the nuclear processes in AGB stars.

description: We present and discuss a formal approach for describing the quantum to classical crossover based on the group-theoretic construction of generalized coherent states. The method was originally introduced by L. Yaffe in 1982 for tackling large-$N$ quantum field theories, and has been recently used for studying open quantum systems whose environment, while becoming macroscopic, may or may not display a classical behaviour. Referring to these recent developments, in this paper we provide the essential elements of Yaffes's approach in the framework of standard quantum mechanics, so as to clarify how the approach can be used without referring to quantum field theory. Moreover, we address the role played by a possible global symmetry in making the large-$N$ limit of the original quantum theory to flow into a formally well defined classical theory, and we specifically consider the quantum-to-classical crossover of angular momentum. We also give details of a paradigmatic example, namely that of $N$ free one-dimensional spinless particles. Finally, we discuss upon the foundational requirement that any classical description should ultimately be derived from an underlying quantum theory, that however is not, and should never be confused with, the one obtained via some quantization procedure of the classical description itself.

description: A number of examples have demonstrated the failure of the Landau-Ginzburg-Wilson(LGW) paradigm in describing the competing phases and phase transitions of two dimensional quantum magnets. In this paper we argue that such magnets possess field theoretic descriptions in terms of their slow fluctuating orders provided certain topological terms are included in the action. These topological terms may thus be viewed as what goes wrong within the conventional LGW thinking. The field theoretic descriptions we develop are possible alternates to the popular gauge theories of such non-LGW behavior. Examples that are studied include weakly coupled quasi-one dimensional spin chains, deconfined critical points in fully two dimensional magnets, and two component massless $QED_3$. A prominent role is played by an anisotropic O(4) non-linear sigma model in three space-time dimensions with a topological theta term. Some properties of this model are discussed. We suggest that similar sigma model descriptions might exist for fermionic algebraic spin liquid phases.
