description: We consider an optically thick spherical agglomerate of magneto-optical scatterers with a central isotropic, unpolarized light source, placed in a homogeneous magnetic field. The Photon Hall Effect induces a rotating Poynting vector, both inside and outside the medium. We show that electromagnetic (orbital) angular momentum leaks out and induces a torque proportional to the injection power of the source and the photon Hall angle. This effect represents a novel class of optical phenomena, generating angular momentum from diffusive magneto-transport.

description: El objetivo del trabajo es cuantificar económicamente impactos ambientales sobre la calidad del suelo, derivados de la implementación de sistemas de laboreo alternativos: siembra directa versus laboreo convencional. El análisis se desarrolla en una finca del sudoeste bonaerense, Argentina, para el período 1986-2008. Se cuantifica económicamente el balance de nutrientes por el método del costo de reposición; y se valoran los servicios ambientales de ambas técnicas mediante la función de producción ajustada, atendiendo sus rendimientos físicos. Se concluye que la siembra directa presenta un mejor desempeño desde las perspectivas estudiadas, especialmente ante escenarios de precipitaciones y niveles de nitrógeno bajos.

description: We consider nematic liquid crystals in a bounded, convex polyhedron described by a director field n(r) subject to tangent boundary conditions. We derive lower bounds for the one-constant elastic energy in terms of topological invariants. For a right rectangular prism and a large class of topologies, we derive upper bounds by introducing test configurations constructed from local conformal solutions of the Euler-Lagrange equation. The ratio of the upper and lower bounds depends only on the aspect ratios of the prism. As the aspect ratio is varied, the minimum-energy conformal state undergoes a sharp transition from being smooth to having singularities on the edges.

description: Single-Pixel Imaging unter Verwendung von Compressive Sensing wurde vor über zehn Jahren erstmals beschrieben. Seither wurde diese Technik in zahlreichen Anwendungen implementiert. Die Möglichkeit Signale, die in bestimmten Domänen dünnbesetzt (Sparse) sind, unterhalb der Shannon-Nyquist Abstastrate zu samplen, ermöglicht es, Datenmengen während des Aufnehmens von Bildern mit Single-Pixel Detektoren zu reduzieren. Die Kombination aus Single-Pixel Imaging und Spektroskopie im nahen Infrarot eröffnet einen neuen, kosten- günstigen Ansatz, um hyperspektrale Bildgebung in ebendiesem Wellenlängenbereich zu betreiben. Dies ist gerade auch deshalb interessant, da Moleküle dort Obertonschwingungen aufweisen, was zur zerstörungsfreien chemischen Analyse von organischen Proben ausgenutzt werden kann. Während herkömmliche hyperspektrale Kameras in diesem Wellenlängenbereich üblicherweise teuer sind und zudem gekühlt werden müssen, präsentiert diese Arbeit eine vergleichsweise kostengünstige, breitbandige (1500 nm - 2200 nm), hyperspektrale Single-Pixel Kamera für das nahe Infrarot. Die Kamera ist aus kommerziell erhältlichen Bauteilen, wie einem Digital Micromirror Device (DMD) und einem Mikrospektrometer aufgebaut. Im Folgenden wird auf das Konzept der entwickelten Hyperspektrale Kamera näher eingegangen. Ergebnisse aus Probemessungen werden präsentiert und zur Charakterisierung des bildgebenden Systems genutzt.
description: Single-pixel imaging via compressive sensing was introduced over a decade ago and has since then made an impressive leap forward. The possibility to sample signals, that show sparsity in a certain domain, below the Shannon-Nyquist sampling rate opens the ability to reduce data amounts whilst recording images with a single-pixel detector element. Combining single-pixel imaging with near-infrared spectroscopy opens a new, cost effective approach to hyperspectral imaging in the near-infrared domain, where molecular overtone vibrations can be exploited to perform chemical identification of samples. While common hyperspectral cameras in this wavelength region tend to be expensive and usually have to be cooled, this work presents a broadband (1500 nm - 2200 nm) hyperspectral near-infrared single-pixel camera built with simple and inexpensive parts, such as a digital micromirror device and a commercially available microspectrometer. In this thesis the developed setup is explained and several samples are investigated in order to characterize the performance of the hyperspectral single-pixel imaging system.

Se define una variable relativa al logro empresarial, a partir de la técnica estadística del análisis de componentes principales que, junto con otros ratios, se introduce en los modelos de regresión. Los resultados no evidencian relación entre estructura financiera y logro empresarial, pero sí corroboran la teoría del Pecking order, apoyando la hipótesis del endeudamiento y la capitalización como fuentes de financiación predominantes. También se verifica la Teoría de la agencia, ya que crecimientos de ventas conllevan un mayor endeudamiento a corto plazo.

description: With the advances of fifth-generation (5G) cellular networks technology, many studies and work have been carried out on how to build 5G networks for smart cities. In the previous research, street lighting poles and smart light poles are capable of being a 5G access point. In order to determine the position of the points, this paper discusses a new way to identify poles based on Mask R-CNN, which extends Fast R-CNNs by making it employ recursive Bayesian filtering and perform proposal propagation and reuse. The dataset contains 3,000 high-resolution images from google map. To make training faster, we used a very efficient GPU implementation of the convolution operation. We achieved a train error rate of 7.86% and a test error rate of 32.03%. At last, we used the immune algorithm to set 5G poles in the smart cities.

description: We present studies of strong coupling in single-photon photoassociation of cesium dimers using an optical dipole trap. A thermodynamic model of the trap depletion dynamics is employed to extract absolute rate coefficents. From the dependence of the rate coefficient on the photoassociation laser intensity, we observe saturation of the photoassociation scattering probability at the unitarity limit in quantitative agreement with the theoretical model by Bohn and Julienne [Phys. Rev. A, 60, 414 (1999)]. Also the corresponding power broadening of the resonance width is measured. We could not observe an intensity dependent light shift in contrast to findings for lithium and rubidium, which is attributed to the absence of a p or d-wave shape resonance in cesium.

description: Many underutilized crops are characterized by high nutritional quality and resilience to abiotic stress, but their yield and agronomic properties are significantly lower compared to major crops. The last decades of genomic, physiological, and population genetic research provide the opportunity to transfer methods to minor crops to accelerate their improvement if knowledge is effectively shared between disciplines. Grain amaranth is an ancient nutritious pseudocereal from the Americas that is regaining importance due to its high protein content and favorable amino acid and micronutrient composition. To effectively combine genomic and population genetic information with molecular genetics, plant physiology, and use it for interdisciplinary research and crop improvement, an intuitive interaction for scientists across disciplines is essential. Here, we present PopAmaranth, a population genetic genome browser, which provides an accessible representation of the geneticv ariation of the three grain amaranth species (A. hypochondriacus, A. cruentus, and A. caudatus) and two wild relatives (A.hybridus and A. quitensis) along theA. hypochondriacus reference sequence. We provide population scale diversity and selection analysis from whole-genome sequencing data of 88 curated genetically and taxonomically unambiguously classified accessions. We incorporate the domestication history of the three grain amaranths to provide an evolutionary perspective for candidate genes. We show that genetic diversity in the water stress-related MIF1 gene declined during amaranth domestication and provide evidence for converged saponin reduction between amaranth and quinoa. These examples show that our tool enables the detailed study of individual genes, provides target regions for breeding efforts, and can enhance the interdisciplinary integration of population genomic findings across species.

description: We consider closed free tensionless strings in $AdS_d$, calculate exactly the boundary/boundary string evolution kernel and find the string dynamics to be completely frozen. We interpret therefore the boundary configurations as Wilson loop operators in a confining phase. This is taken as an argument in favor to the dual weakly coupled abelian gauge theory being that of $(d-4)$-forms in the $(d-1)$ dimensional boundary Minkowski space.

description: Ce texte présente trois scénarios de modulation des aides du premier pilier en vue de renforcer le deuxième pilier. Compte tenu du poids des aides dans le revenu, une redistribution plus égalitaire des subventions ne correspond pas automatiquement à une nette baisse de l’inégalité des revenus. La répartition des revenus dépend aussi très largement de l’évolution des prix relatifs des produits agricoles.
Statistical list-mode image reconstruction and motion compensation techniques in high-resolution positron emission tomography (PET)
Creators: name: Rahmim, Arman
Publisher: name: University of British Columbia
Year: 2009

description: The work presented here is devoted to the proposal and investigation of 3D image reconstruction algorithms suitable for high resolution positron emission tomography (PET). In particular, we have studied imaging techniques applicable to the high resolution research tomograph (HRRT): a 3Donly state-of-the-art dedicated brain tomograph. The HRRT poses a number of unique challenges, most significant of which include presence of gaps in-between the detector heads, as well as the very large number of lines-ofresponse (LORs) which it is able to measure (~4.5x10⁹), exceeding most modern PET scanners by 2-3 orders of magnitude. To address the existing issues, we have developed and implemented statistical list-mode image reconstruction as a powerful technique applicable to the high resolution data obtained by the HRRT. We have furthermore verified applicability of this technique to dynamic (4D) PET imaging, thus qualifying the technique as viable and accurate for the research intended to be performed on the scanner. We have paid particular attention to the study of convergent algorithms; i.e. iterative algorithms which (with further iterations) consistently improve such figures of merit as resolution and contrast, relevant to research and clinical tasks. With the spatial resolution in modern high resolution tomographs (including the HRRT) reaching the 2-3mm FWHM range, small patient movements during PET imaging can become a significant source of resolution degradation. We have thus devoted a portion of this dissertation to the proposal of new, accurate and practical motion-compensation techniques, and studied them on the HRRT. We have theoretically proposed and experimentally validated the benefits of modeling the motion into the reconstruction task, thus signaling the way beyond the existing purely event-driven motioncompensation techniques.

description: In this paper we study how the (normalised) Gagliardo semi-norms $[u]_{W^{s,p} (\mathbb{R}^n)}$ control translations. In particular, we prove that $\| u(\cdot + y) - u \|_{L^p (\mathbb{R}^n)} \le C [ u ] _{W^{s,p} (\mathbb{R}^n)} |y|^s$ for $n\geq1$, $s \in [0,1]$ and $p \in [1,+\infty]$, where $C$ depends only on $n$. We then obtain a corresponding higher-order version of this result: we get fractional rates of the error term in the Taylor expansion. We also present relevant implications of our two results. First, we obtain a direct proof of several compact embedding of $W^{s,p}(\mathbb{R}^n)$ where the Fréchet-Kolmogorov Theorem is applied with known rates. We also derive fractional rates of convergence of the convolution of a function with suitable mollifiers. Thirdly, we obtain fractional rates of convergence of finite-difference discretizations for $W^{s,p} (\mathbb{R}^n))$.

description: We find convergent double series expansions for Legendre's third incomplete elliptic integral valid in overlapping subdomains of the unit square. Truncated expansions provide asymptotic approximations in the neighbourhood of the logarithmic singularity $(1,1)$ if one of the variables approaches this point faster than the other. Each approximation is accompanied by an error bound. For a curve with an arbitrary slope at $(1,1)$ our expansions can be rearranged into asymptotic expansions depending on a point on the curve. For reader's convenience we give some numeric examples and explicit expressions for low-order approximations.

description: Si l’intérêt des biocarburants pour la sécurité énergétique et la lutte contre le réchauffement climatique est aujourd’hui fortement débattu en Europe, nul ne conteste qu’ils ont un effet bénéfique sur l’agriculture européenne. Nous évaluons les impacts sur les différents marchés et revenus agricoles européens d’une application complète de la directive européenne de promotion de ces biocarburants. Cette évaluation tient compte des possibilités d’importation de ces produits en provenance du marché mondial ainsi que des effets induits sur l’élevage. Nous montrons des effets substantiels sur les marchés des grandes cultures et des effets très modestes sur les marchés des produits d’élevage. Le revenu agricole total augmente mais de manière limitée par rapport aux dépenses pubiques injectées.

description: In this work the potential mineral identification of meteorites is analysed for the mid-infrared range, to evaluate observational possibilities for future missions targeting small body surfaces. Three carbonaceous and three ordinary chondrite meteorites are examined by a diffuse reflection (DRIFT) instrument, and the presence of principal minerals is confirmed by a powder diffraction method as well. The possibilities and constraints of mineral identifications in the mid-infrared are simulated by artificially degrading the spectral resolution. Our research shows that for the definite identification of principal mineral bands, a spectral resolution $\leq 10$~cm$^{-1}$ ($\leq 0.15 μ$m) is needed. At 20-100~cm$^{-1}$ (0.3 - 1.5~$μ$m) resolution the identification of these minerals is uncertain, and with a resolution $>100$~cm$^{-1}$, it is almost impossible.

description: En mars 2007, le Conseil européen a annoncé qu’à l’horizon 2020, une proportion minimale de 10 % de biocarburants devrait être incorporée dans les carburants utilisés pour le transport routier. Les pouvoirs publics communautaires mettent en avant trois facteurs principaux pour justifier une telle ambition : la réduction des émissions de gaz à effet de serre (GES), la diversification des approvisionnements énergétiques et le soutien des revenus agricoles. Alors qu’on s’interroge sur les conditions dans lesquelles les 5,75 % d’incorporation fixés par le cadre législatif actuel pourraient être atteints en 2010, ce nouvel élan donné à la politique communautaire des biocarburants suscite plusieurs interrogations.
title: Experience sampling of the psychosocial work environment: from hedonometrics to hedonopragmatics
Creators: name: Metze, Jacob F.
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2020

description: Current research that uses the experience sampling method (ESM) in an organisational context has focused on individuals in order to advance the theories and metrics regarding employees’ work experiences. What is notable is the lack of focus on the pragmatic potential of the method to mobilise change in organisations. Participatory interventions based on survey feedback are shown to be effective, but rely on questionnaire data with well-known limitations for capturing the dynamic nature of employee experiences. The ESM addresses and overcomes some of these limitations but has yet to be applied to feedback interventions. This research investigates how an ESM approach to survey feedback in an organisational context mobilises change efforts with a focus on the psychosocial work environment. The study serves two purposes. First, it investigates the semantic equivalence between the questionnaire metrics and new ESM measures of the psychosocial work environment, where questions are sampled from a pool of items at each time sampling occasion (hedonometrics). Second, it assesses whether the ESM exceeds traditional survey feedback when mobilising collective change efforts (hedonopragmatics). A longitudinal experimental study design is applied within a Danish higher education institution. Ten naturally established work groups are assigned to either an ESM or a questionnaire survey condition. Each unit participates in an intervention with extensive data feedback and a follow-up procedure 8–16 months later. Data include survey responses, action plans and observations of feedback conferences. The results provide partial support for the semantic equivalence of the ESM sampling and the questionnaire approach. All three data sources indicate greater change mobilisation for the ESM compared to the questionnaire condition. It is concluded that the added value of the ESM extends beyond its use as a better metric at the individual level. It also has pragmatic and emancipatory potential for sensemaking at the group level in organisations.

description: We consider the role of the Ward identity in dealing with the transport properties of an interacting system forming a d-wave modulated charge-density wave or staggered flux phase. In particular, we address this issue from the point of view of the restricted optical-conductivity sum rule. Our aim is to provide a controlled approximation for the current-current correlation function which allows us also to determine analytically the corresponding sum rule. By analyzing the role of the vertex functions in both the microscopic interacting model and in the effective mean-field Hamiltonian, we propose a non-standard low-energy sum-rule for this system. We also discuss the possible applicability of these results for the description of cuprate superconductors in the pseudogap regime.

Empathic leadership in sustainability planning
Creators: name: Senbel, Maged
Publisher: name: University of British Columbia
Year: 2009

description: Analysis of planning practice has led theorists to claim that planners are increasingly involved in communicative work as they negotiate between competing interests' and opposing parties. A normative study of the resultant theory of communicative planning, alongside a review of current trends in leadership and mediation literature, leads to a set of guiding attributes of conduct and action. This research begins by synthesizing these guiding attributes of effective planning into a framework of Empathic Leadership. In sustainability planning Empathic Leadership is particularly concerned with mediating between different perspectives while simultaneously advancing a specific agenda. The work of eight sustainability planners in the Vancouver region, each a leader in her respective field, was analyzed using the Empathic Leadership framework. Planners were interviewed shadowed and observed, and their staff and colleagues were surveyed to gain multiple perspectives on the significance of the various attributes of leadership. Empathic Leadership was found to permeate every aspect of the practitioners' work and they were found to possess many of the skills necessary for being exemplary leaders. The research also revealed that their work is an iterative pentad of: visioning, engaging emotions, building community, employing strategy and implementing action. The visions are compelling, seductive and infectious yet ambiguous. Emotions are strong and recognized as being significant, yet poorly integrated into the other elements of the pentad. Communities rallying around the visions are cohesive, fluid, diverse and context-specific, but largely untested. The strategies are political, relatively transparent but rarely uphold the inclusive values of the vision. Actions are varied, innovative and often democratizing, yet implicitly homogenous and classist. While ample evidence of communicative planning exists, it is an unrealized ideal; the reality is a temporally larger scope of relational planning whereby change is achieved through the building of relationships over time.

description: L’Accord agricole du cycle de l’Uruguay (AACU) marque la fin d’une époque où les politiques agricoles pouvaient être élaborées indépendamment des règles internationales. Il a défini un cadre de travail, avec engagements distincts sur les trois dossiers de la concurrence à l’exportation, de l’accès au marché et du soutien interne, qui est repris à l’occasion du cycle de Doha. Ce cadre reconnaît explicitement que des politiques domestiques peuvent avoir des effets de distorsion sur les échanges et à ce titre, être soumises à disciplines dans le contexte de négociations multilatérales portant sur les échanges. Cet article traite de la question du soutien interne dans le cycle de Doha, plus spécifiquement : l’évolution des négociations sur la question depuis le lancement du cycle jusqu’à ce jour ; l’impact potentiel pour l’Union européenne (UE) des engagements qui seraient pris au titre du soutien interne ; l’analyse critique des discussions sur ce dossier.

description: The purpose of this paper is to empirically show the relative importance of the agricultural sector in the productive framework of Mato Grosso State (Brazil), an inter-regional input-output model for two regions: Mato Grosso and the rest of Brazil for 1999. The idea was to identify the most important sectors of the economies in question, their connections and the propagation of impacts between regions, besides verifying the impact on the Mato Grosso soybean exports on the total production of other activities. The hypothesis on the importance of the primary sectors for the state economy has been confirmed, and some agricultural sectors and others directly linked thereto have been found to be key-sectors, or centers of economic growth in the region under study. Special mention should be given to soybean culture in Mato Grosso State, which shows a high employment and income multiplying effect on the economy, as well as being a center of economic growth and major exporter, attracting exchange gains to the country and positively impacting the production of other sectors. Finally, this paper provides a useful tool for drafting public policies for Mato Grosso State.

description: Recently, a massive magnetocaloric effect near the liquefaction temperature of hydrogen has been reported in the ferromagnetic material HoB$_{2}$. Here we investigate the effects of Dy substitution in the magnetocaloric properties of Ho$_{1-x}$Dy$_{x}$B$_{2}$ alloys ($\textit{x}$ = 0, 0.3, 0.5, 0.7, 1.0). We find that the Curie temperature ($\textit{T}$$_{C}$) gradually increases upon Dy substitution, while the magnitude of the magnetic entropy change |$Δ\textit{S}_{M}$| at $\textit{T}$ = $\textit{T}_{C}$ decreases from 0.35 to 0.15 J cm$^{-3}$ K$^{-1}$ for a field change of 5 T. Due to the presence of two magnetic transitions in these alloys, despite the change in the peak magnitude of |$Δ\textit{S}_{M}$|, the refrigerant capacity ($\textit{RC}$) and refrigerant cooling power ($\textit{RCP}$) remains almost constant in all doping range, which as large as 5.5 J cm$^{-3}$ and 7.0 J cm$^{-3}$ for a field change of 5 T. These results imply that this series of alloys could be an exciting candidate for magnetic refrigeration in the temperature range between 10-50 K.

title: The state and rural credit markets in south India, 1930-1960

description: This thesis contributes to a central theme in the economic history of India: state intervention to protect peasants from market fluctuations, especially, interventions in the credit market. With novel material drawn from the Madras region in late-colonial and early post-colonial times, the thesis asks why unregulated credit markets did not supply enough credit and why regulations exacerbated the problem. Private moneylenders controlled the supply of rural credit in colonial India. Officials believed that rich moneylenders exploited poor peasants in non-competitive credit markets, raising borrowing costs and default rates, restricting investment and widening rural inequality. Based on that understanding, governments in the provinces enforced laws to protect borrowers. The government in Madras adopted two policy approaches to rural credit that were specific to the province. First, from 1904 it established cooperative banks to compete with private lenders. Second, from 1937 it enforced an artificial price ceiling on loans from moneylenders. This thesis aims to show that intervention failed owing to the nature of the agricultural economy and the political-economic ideology that privileged equity over efficiency. The first and second substantive chapters critically discuss the view, voiced by government officials and some historians, that exploitation drove high borrowing costs and defaults. By looking at the costs borne by the moneylender, the chapters show that the frequency of crop failure and inefficient courts explain restricted credit supply as well as default and interest rate patterns. The third chapter evaluates the impact of credit intervention and demonstrates that the price ceiling failed to deliver equity gains and triggered losses in market efficiency as credit supply contracted and moneylenders evaded the law. The outcome was limited credit supply and lending at illegal rates of interest. The fourth chapter analyses the performance of cooperative banks in rural Madras. The chapter shows that regulatory design explains the failure of the cooperative model. The rich refused to cooperate with the poor while bank managers embezzled and falsified accounts.

description: Discrete wavelets are applied to parametrization of the intra-chain two-point correlation functions of homopolymers in dilute solutions obtained from Monte Carlo simulation. Several orthogonal and biorthogonal basis sets have been investigated for use in the truncated wavelet approximation. Quality of the approximation has been assessed by calculation of the scaling exponents obtained from des Cloizeaux ansatz for the correlation functions of homopolymers with different connectivities in a good solvent. The resulting exponents are in a better agreement with those from the recent renormalisation group calculations as compared to the data without the wavelet denoising. We also discuss how the wavelet treatment improves the quality of data for correlation functions from simulations of homopolymers at varied solvent conditions and of heteropolymers.

Bons alimentos cada vez mais caros: análise da evolução dos preços dos alimentos no Brasil.

description: Que a alimentação é importante para a manutenção da saúde não há dúvidas. Pode haver inconsistências em relação ao quanto se deve comer de cada alimento ou nutriente, ou o quanto isso nos protege de desenvolver doenças no futuro. No entanto, é certo que pessoas que se alimentam melhor têm um risco menor de ter doenças do coração, alguns tipos de cânceres e obesidade, entre outras doenças[1].

Há diversas razões pelas quais as pessoas, de modo geral, não conseguem se alimentar de forma mais saudável no Brasil e no mundo. Dois aspectos são importantes: preferências alimentares e os preços dos alimentos[2]. O último aspecto pode não ser somente uma limitação para melhora nas escolhas alimentares, mas também para manutenção da alimentação. O problema se agrava quando o aumento nos preços dos alimentos é maior que o aumento no rendimento das famílias. No Brasil, pelo menos para aqueles que têm seu rendimento vinculado ao salário-mínimo, cuja correção anual acompanha a inflação, este descompasso é uma absurda realidade.

description: The efficacy of nefopam, a non-opioid, non-steroidal, central acting drug, for cancer pain remains unclear. We evaluated the analgesic efficacy of nefopam for cancer pain in a randomized controlled. Patients with moderate to severe cancer pain (n=40) were randomly divided into two groups. The nefopam group (n=20) received three 20 mg doses of nefopam every 8 hours. The placebo group (n=20) received normal saline. Intravenous patient-controlled analgesia with morphine was given for breakthrough pain for 48 hours. The primary outcome was significant pain reduction. Secondary outcomes were morphine consumption over 48 hours and incidence of side effects.Article relating to this data published on F1000Research: DOI 10.12688/f1000research.23455.1.

description: In this work, we have studied the electronic structure of a promising thermoelectric half-Heusler FeVSb using FP-LAPW method and SCAN meta-GGA including spin-orbit coupling. Using the obtained electronic structure and transport calculations we try to address the experimental Seebeck coefficient $S$ of FeVSb samples. The good agreement between the experimental and calculated $S$ suggests the band gap could be $\sim$0.7 eV. This is supported by the obtained mBJ band gap of $\sim$0.7 eV. Further, we study and report the phonon dispersion, density of states and thermodynamic properties. The effect of long range Coulomb interactions on phonon frequencies are also included by non-analytical term correction. Under quasi-harmonic approximation, the thermal expansion behaviour upto 1200 K is calculated. Using the first-principles anharmonic phonon calculations, the lattice thermal conductivity $κ_{ph}$ of FeVSb is obtained under single-mode relaxation time approximation considering the phonon-phonon interaction. At 300 K, the calculated $κ_{ph}$ is $\sim$18.6 W$m^{-1}K^{-1}$ which is higher compared to experimental value. But, above 500 K the calculated $κ_{ph}$ is in good agreement with experiment. A prediction of figure of merit $ZT$ and efficiency for p-type and n-type FeVSb is made by finding out optimal carrier concentration. At 1200 K, a maximum $ZT$ of $\sim$0.66 and $\sim$0.44 is expected for p-type and n-type FeVSb, respectively. For p-type and n-type materials, maximum efficiency of $\sim$12.2 \% and $\sim$6.0 \% are estimated for hot and cold temperature of 1200 K and 300 K, respectively. A possibility of achieving n-type and p-type FeVSb by various elemental doping/vacancy is also discussed. Our study is expected to help in further exploring the thermoelectric material FeVSb.

description: Distinct orders of priorities for the demands shared by diverse stakeholders create a complex system of interests. The ability to argue can bias the collective ranking of priorities, discouraging people to get engaged in the fulfillment of the diverse demands. It is supposed that the motivation of a group in implementing actions is proportional to the compatibility of the original ranking or the re-ranking of priorities based on individual reflections regarding what others give priority. In the method here proposed, the identification of the degree of conformity among distinct interests is a mathematical product of the relations among the original rankings, while the promotion of a higher convergence of these rankings is mediated exclusively by individual reflection. As an indicator of sustainability to be derived, the degree of compatibility of the distinct interests that drive the distinct rankings is characterized as a measure of the possibilities of effective engagement of all interested. The systematization of relations resulted in an objective and operational Indicator of Sustainability in a System of Interests – 0 ≤ ISSI ≤ 1.
