Publisher: name: Gestão e Desenvolvimento
Year: 2017

description: Enquadramento: A indisciplina escolar, como problemática emergente, que nos últimos anos tem vindo a ganhar relevo na comunidade educativa, tem desencadeado um conjunto de reações e múltiplas preocupações nos mais variados quadrantes da Sociedade Portuguesa. Neste contexto, o presente estudo teve como objetivo geral explorar as relações existentes entre determinantes de contexto sociodemográfico, familiar e religioso e a indisciplina escolar percepcionada pelos alunos. Material e Método: Recorrendo a um estudo de natureza quantitativa, do tipo transversal com características descritivo-correlacionais, inquirimos 772 alunos adolescentes portugueses, na sua maioria do género feminino (52,1%), com idades compreendidas entre os 12 e os 17 anos (M=13,33; Dp=1.042), residentes em meio rural (51,2%), pertencentes à classe socioeconómica III – Classe Média (48,4%) e que frequentam o terceiro ciclo do ensino básico público. O protocolo de pesquisa incluiu instrumentos de medida aferidos e validados para a população portuguesa e a Escala de Indisciplina Escolar Percepcionada por Alunos (EIEPA), cujas propriedades psicométricas certificam a sua qualidade (Alfa de Cronbach = 0,960; Alfa de Cronbach teste re-teste = 0,911). Resultados: As variáveis sociodemográficas (idade, sexo e local de residência) revelaram um efeito estatisticamente significativo sobre a Indisciplina Escolar Percepcionada pelos Alunos. Também se constatou a existência de associações estatisticamente significativas entre as variáveis de contexto religioso (grau de crença na religião e grau de praticante) e todos os factores da escala EIEPA. No que respeita ao estudo do efeito da existência de conversas com o encarregado de educação sobre a forma como o estudante de comporta na escola, o mesmo permitiu inferir que este efeito assume significância estatística sobre todos os factores da Indisciplina Escolar Percecionada por Alunos. Conclusão: As inferências resultantes desta investigação convidam-nos à reflexão sobre a importância da criação e monitorização de programas de ação no domínio da prevenção ou de contingência para uma efetiva redução dos comportamentos indisciplinados perpetrados por Alunos no seio da Escola. Fica claro que esta tarefa, sendo urgente, tem de ser articulada entre toda a comunidade educativa, com envolvimento direto dos pais/encarregados de educação, bem como de outros protagonistas no sentido de se desenvolverem estratégias de intervenção dirigidas às reais necessidades dos adolescentes

description: O termo rural tem significados diferentes para diferentes pessoas. Desde uma paisagem bucólica até zonas remotas, atrasadas e com tradições ancestrais, passando por lugares onde se produzem alimentos e matérias-primas para o sector secundário, tudo cabe na definição do termo rural. A confusão fica a dever-se a algumas das características que, tradicionalmente, definem o mundo rural, tais como: actividade agrícola dos seus habitantes, forte dependência dos recursos naturais e extracção de matérias-primas, características que não esgotam as especificidades do mundo rural.

description: The applicability of agglomerative clustering, for inferring both hierarchical and flat clustering, is limited by its scalability. Existing scalable hierarchical clustering methods sacrifice quality for speed and often lead to over-merging of clusters. In this paper, we present a scalable, agglomerative method for hierarchical clustering that does not sacrifice quality and scales to billions of data points. We perform a detailed theoretical analysis, showing that under mild separability conditions our algorithm can not only recover the optimal flat partition, but also provide a two-approximation to non-parametric DP-Means objective. This introduces a novel application of hierarchical clustering as an approximation algorithm for the non-parametric clustering objective. We additionally relate our algorithm to the classic hierarchical agglomerative clustering method. We perform extensive empirical experiments in both hierarchical and flat clustering settings and show that our proposed approach achieves state-of-the-art results on publicly available clustering benchmarks. Finally, we demonstrate our method's scalability by applying it to a dataset of 30 billion queries. Human evaluation of the discovered clusters show that our method finds better quality of clusters than the current state-of-the-art.

description: We study the temporal fluctuations in time-dependent stock prices (both individual and composite) as a stochastic phenomenon using general techniques and methods of nonequilibrium statistical mechanics. In particular, we analyze stock price fluctuations as a non-Markovian stochastic process using the first-passage statistical concepts of persistence and survival. We report the results of empirical measurements of the normalized $q$-order correlation functions $f_q(t)$, survival probability $S(t)$, and persistence probability $P(t)$ for several stock market dynamical sets. We analyze both minute-to-minute and higher frequency stock market recordings (i.e., with the sampling time $δt$ of the order of days). We find that the fluctuating stock price is multifractal and the choice of $δt$ has no effect on the qualitative multifractal behavior displayed by the $1/q$-dependence of the generalized Hurst exponent $H_q$ associated with the power-law evolution of the correlation function $f_q(t)\sim t^{H_q}$. The probability $S(t)$ of the stock price remaining above the average up to time $t$ is very sensitive to the total measurement time $t_m$ and the sampling time. The probability $P(t)$ of the stock not returning to the initial value within an interval $t$ has a universal power-law behavior, $P(t)\sim t^{-θ}$, with a persistence exponent $θ$ close to 0.5 that agrees with the prediction $θ=1-H_2$. The empirical financial stocks also present an interesting feature found in turbulent fluids, the extended self-similarity.

description: Presently, there are no approved drugs or vaccines to treat COVID-19 which has spread to over 200 countries and is responsible for over 3,65,000 deaths worldwide. Recent studies have shown that two human proteases, TMPRSS2 and cathepsin L, play a key role in host cell entry of SARS-CoV-2. Importantly, inhibitors of these proteases were shown to block SARS-CoV-2 infection. Here, we perform virtual screening of 14010 phytochemicals produced by Indian medicinal plants to identify natural product inhibitors of TMPRSS2 and cathepsin L. We built a homology model of TMPRSS2 as an experimentally determined structure is not available. AutoDock Vina was used to perform molecular docking of phytochemicals against TMPRSS2 model structure and cathepsin L crystal structure. Potential phytochemical inhibitors were filtered by comparing their docked binding energies with those of known inhibitors of TMPRSS2 and cathepsin L. Further, the ligand binding site residues and non-covalent protein-ligand interactions were used as an additional filter to identify phytochemical inhibitors that either bind to or form interactions with residues important for the specificity of the target proteases. We have identified 96 inhibitors of TMPRSS2 and 9 inhibitors of cathepsin L among phytochemicals of Indian medicinal plants. The top inhibitors of TMPRSS2 are Edgeworoside C, Adlumidine and Qingdainone, and of cathepsin L is Ararobinol. Interestingly, several herbal sources of identified phytochemical inhibitors have antiviral or anti-inflammatory use in traditional medicine. Further in vitro and in vivo testing is needed before clinical trials of the promising phytochemical inhibitors identified here.

description: We address the problem of completely characterizing multi-particle states including loss of information to unobserved degrees of freedom. In systems where non-classical interference plays a role, such as linear-optics quantum gates, such information can degrade interference in two ways, by decoherence and by distinguishing the particles. Distinguishing information, often the limiting factor for quantum optical devices, is not correctly described by previous state-reconstruction techniques, which account only for decoherence. We extend these techniques and find that a single modified density matrix can completely describe partially-coherent, partially-distinguishable states. We use this observation to experimentally characterize two-photon polarization states in single-mode optical fiber.

The flow is found to be unstable at high Mach numbers, with the instability appearing even for a larger accretor. The instability appears to be the unstable radial mode of the accretion column predicted by earlier analytic work.

description: Nuclear collisions at high energies produce a gluon field that can be described using the Colour Glass Condensate (CGC) effective theory at proper times $τ\lesssim 1$ fm/c. The theory can be used to calculate the gluon energy-momentum tensor, which provides information about the early time evolution of the chromo-electric and chromo-magnetic fields, energy density, longitudinal and transverse pressures, and other quantities. We obtain an analytic expression for the energy-momentum tensor using an expansion in the proper time, and working to sixth order. The calculation is technically difficult, in part because the number of terms involved grows rapidly with the order of the $τ$ expansion, but also because of several subtle issues related to the definition of event-averaged correlators, the method chosen to regulate these correlators, and the dependence of results on the parameters introduced by the regularization and nuclear density profile functions. All of these issues are crucially related to the important question of the extent to which we expect a CGC approach to be able to accurately describe the early stages of a heavy ion collision. We present some results for the evolution of the energy density and the longitudinal and transverse pressures. We show that our calculation gives physically meaningful results up to values of the proper time which are close to the regime at which hydrodynamic simulations are initialized. In a companion paper [1] we give a detailed analysis of several other experimentally relevant quantities that can be calculated from the energy-momentum tensor.

description: We use large scale simulations to study interacting particles in two dimensions in the presence of both an ac drive and quenched disorder. As a function of ac amplitude, there is a crossover from a low drive regime where the colloid positions are highly disordered to a higher ac drive regime where the system dynamically reorders. We examine the coarsening of topological defects formed when the system is quenched from a disordered low ac amplitude state to a high ac amplitude state. When the quench is performed close to the disorder-order crossover, the defect density decays with time as a power law with α= 1/4 to 1/3. For deep quenches, in which the ac drive is increased to high values such that the dynamical shaking temperature is strongly reduced, we observe a logarithmic decay of the defect density into a grain boundary dominated state. We find a similar logarithmic decay of defect density in systems containing no pinning. We specifically demonstrate these effects for vortices in thin film superconductors, and discuss implications for dynamical reordering transition studies in these systems.

description: O debate nacional acerca da gestão dos estabelecimentos de ensino básico e secundário tem estado centrado em problemas curriculares e disciplinares sem atender a questões relevantes nos domínios da eficiência. O presente texto procura trazer para o cerne do debate a necessidade de se dispor de indicadores fiáveis e facilmente interpretáveis por um conjunto vasto de atores sociais interessados na eficiência das organizações escolares. Na ausência desta comparabilidade entre estabelecimentos escolares dificilmente se poderá escapar a uma captura do debate democrático por interesses meramente corporativos e ou pela questão ideológica, afastando deste os principais interessados, os pais e outros atores pertinentes da comunidade educativa envolvente. O estudo de caso que suporta a apresentação e interpretação de indicadores de gestão revela que a procura de indicadores de eficiência permite, por um lado, levantar questões pertinentes de eficácia subjacentes e por outro, ganhar os docentes e outros funcionários para uma tomada de consciência da importância da gestão dos recursos humanos disponíveis nestas organizações.

description: We explore the possibility of gauge mediation in a paradigm whereby supersymmetry is posited to be an accidental symmetry of Nature and the Standard Model fields are composite bound states that emerge from a conformal field theory. The resultant effective theory can, through sequestering and conformal dynamics, exhibit most of the properties of low energy supersymmetry breaking while averting a number of cosmological and astrophysical constraints of the traditional framework of gauge mediation via dynamical supersymmetry breaking. Of particular phenomenological interest is that in our scenario, the gravitino is superheavy, the neutralino LSP is a viable candidate for cold dark matter and the flavor changing neutral currents are constrained to be, at the very minimum, only an order of magnitude below current experimental bounds.

description: Reconhecido o fracasso da universalização do acesso à Educação, na promoção da igualdade de oportunidades, assiste-se à mudança do paradigma quantitativo para o paradigma qualitativo. Esta mudança parece enquadrar-se num movimento mais amplo que afeta o Estado, na generalidade dos países. Este artigo propõe um itinerário possível para uma hermenêutica do conceito de Qualidade em Educação, no contexto de mudança vivido neste início do Século XXI. Para o efeito, são mobilizadas diversas abordagens, nomeadamente, a sociológica, a económica, a política e a da investigação educacional. O modelo conceptual, resultante das várias perspetivas, traduz a complexidade e a polissemia do conceito.

description: Superconductivity has recently been observed in Sr-doped NdNiO2 films grown on SrTiO3. Whether it is caused by or related to the interface remains an open question. To address this issue, we use density functional theory calculation and charge transfer self-consistent model to study the effects of polar discontinuity on the electronic and atomic reconstruction at the NdNiO2/SrTiO3 interface. We find that sharp interface with pure electronic reconstruction only is energetically unfavorable, and atomic reconstruction is unavoidable. We further propose a possible interface configuration that contain residual apical oxygen. These oxygen atoms lead to hybrids of dz2 and dx2-y2 states at the Fermi level, which weaken the single-band feature and may be detrimental to superconductivity.

description: We investigate the possibility of defining states on timelike hypersurfaces in quantum field theory. To this end we consider hyperplanes in the real massive Klein-Gordon theory using the Schroedinger representation. We find a well defined vacuum wave functional, existing on any hyperplane, with the remarkable property that it changes smoothly even under Euclidean rotation through the light-cone. Moreover, particles on timelike hyperplanes exist and occur in two variants, incoming and outgoing, distinguished by the sign of the energy. Multi-particle wave functionals take a form similar to those on spacelike hypersurfaces. The role of unitarity and the inner product is discussed.

description: By numerically solving the Bogoliubov-de Gennes equations for the single vortex state in a two-band superconductor, we demonstrate that the disparity between the healing lengths of two contributing condensates is strongly affected by the band Fermi velocities, even in the presence of the magnetic field and far beyond the regime of nearly zero Josephson-like coupling between bands. Changing the ratio of the band Fermi velocities alters the temperature dependence of the condensate lengths and significantly shifts parameters of the ``length-scales locking" regime at which the two characteristic lengths approach one another.

description: Este artigo apresenta os resultados de um estudo efectuado com 153 enfermeiros-chefes e enfermeiros especialistas responsáveis de serviço e teve como principal objectivo identificar o estilo de liderança que estes evidenciam na gestão dos serviços hospitalares. Partindo do modelo e da escala L.P.C. de Fiedler (1967) procedeu-se a um estudo de carácter exploratório, descritivo e correlacional, através dos métodos da investigação quantitativa. Os resultados obtidos sugerem em termos de estilo de liderança, que consoante aumenta o tempo de serviço, tempo de chefia e a idade, os enfermeiros tendem a ter maior orientação para o relacionamento. Assim como, os enfermeiros da especialidade de saúde mental têm maior orientação para o relacionamento do que os enfermeiros da médico-cirúrgica. Por outro lado, os homens, face às mulheres, manifestam em termos de estilo de liderança, maior motivação para a tarefa.

Género e liderança na escola: da feminização da profissão docente ao desempenho de cargos de topo

description: A discriminação social da mulher, ao longo de séculos, ainda hoje ecoa nas sociedades contemporâneas. A alteração do estatuto da mulher, agora com acesso à educação e ao emprego, não bastou para findar a construção de pressupostos de desigualdade social entre homens e mulheres. Embora o princípio de igualdade esteja legalmente estabelecido, as mulheres continuam sub-representadas nas posições de tomada de decisões. O fenómeno ganha maior significado quando consideramos profissões altamente feminizadas, como é o caso da profissão docente. À semelhança do que ocorre na esfera doméstica, a mulher acaba por desempenhar um papel secundário, contrastando com o protagonismo do homem. O trabalho de investigação desenvolvido pretende conhecer algumas das representações e conceções que os docentes têm do género e qual a sua influência na eleição dos Conselhos Executivos, órgãos colegiais eleitos pelos membros da comunidade educativa. O enfoque segundo a condição social da mulher, percorrendo a trajetória histórica da relação da mulher com a família e o trabalho, permitiu uma visão geral da forma como os domínios público e privado interferem no acesso das mulheres a cargos de gestão das escolas. Num espaço que se diz, e que se quer, democrático, é pertinente que se percebam, pois, quais os fatores que perpetuam a hierarquização social entre homens e mulheres. A nossa abordagem incidiu sobre as dimensões da problemática em contexto escolar, nomeadamente a organização, o género e a liderança, com as quais construímos o quadro teórico que sustentou a investigação. O estudo realizado junto dos docentes socorreu-se de uma metodologia quantitativa e qualitativa, através da qual procurámos compreender o modo como os professores percecionam o género e até que ponto este é preponderante na escolha de quem está à frente das escolas.

Influence of cambial ageing, initial spacing, stem taper and growth rate on the wood quality of three coastal conifers
Creators: name: Fabris, Stéphanne
Publisher: name: University of British Columbia
Year: 2009

description: As the forest industry in British Columbia becomes increasingly dependent on second-growth timber for its raw material supply, the question of wood quality becomes more relevant. Accelerated growth in forest plantations, coupled with an earlier harvest, will lead to changes in the quality of the timber harvested. The influence of cambial aging, initial spacing, stem taper and growth rate was non-destructively evaluated on the wood quality characteristics of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii), western hemlock (Tsuga heterophylla (Raf.) Sarg.) and western redcedar (Thuja plicata Donn ex D. Don). The wood properties analysed included ring width, earlywood width, latewood width, latewood proportion, earlywood relative density, latewood relative density, whole-ring relative density, whole-ring tracheid length and microfibril angle. Juvenile wood development was determined based on whole-ring relative density trends from pith to bark. A highly significant cambial age effect was noted for practically each wood property considered. An identical pattern of development, regardless of spacing or taper class, was identified for Douglas-fir via latewood proportion and whole-ring relative density, and for western hemlock via latewood width, earlywood relative density, latewood relative density, whole-ring tracheid length and microfibril angle. No identical results were identified for western redcedar. An increasingly non-significant relationship evolved over time for Douglas-fir between growth rate and whole-ring relative density. A slight, but increasingly negative relationship unfolded for western hemlock. An increasingly stronger negative relationship developed for western redcedar. The Kajaani FS-200 Optical Fibre Analyser was found inadequate for measuring tracheid length variability on the basis of 12 mm increment cores. A gradual decrease in juvenile wood ring count was commonly identified with increasing height. Generally speaking for both Douglas-fir and western hemlock, the larger the volume of crown foliage relative to length of branch-free stem, the lower the passage from juvenile wood to mature wood below the base of the live crown. In the case of western redcedar, the larger the volume of crown foliage relative to length of branch-free stem, the higher the passage. The use of a variable exponent taper equation was explored for predicting juvenile core development.

description: Quantum sensors exploiting matter waves interferometry promise to realize a new generation of Gravitational Wave detectors. The intrinsic stability of specific atomic energy levels makes atom interferometers and clocks ideal candidates to extend the frequency window for the observation of Gravitational Waves in the mid-frequency band, ranging from 10 mHz to 10 Hz. We present the geometry and functioning of this new class of ground and space detectors and detail their main noise sources. We describe the different projects undertaken worldwide to realize large scale demonstrators and push further the current limitations. We finally give the roadmap for achieving the instrumental sensitivity required to seize the scientific opportunities offered by this new research domain.

description: The currently favored scenario for the progenitor evolution of Type Ia supernovae (SNe Ia) presumes that white dwarfs in close binary systems grow to the Chandrasekhar limit via mass accretion from their non-degenerate companions. However, the accreted hydrogen and/or helium usually participate thermally unstable or even violent nuclear reactions in a geometrically confined region, due to the compactness of the white dwarf. Since shell flashes induced by the thermal instability might induce significant loss of mass, efficient mass increase of white dwarfs by hydrogen and/or helium accretion has been seriously questioned. A good understanding of the stability of thermonuclear shell sources is therefore crucial in order to investigate the evolution of accreting white dwarfs as SNe Ia progenitors. Here, we present a quantitative criterion for the thermal stability of thermonuclear shell sources, and discuss the effects of rotation on the stability of helium shell burning in helium accreting CO white dwarfs with Mdot \approx 10^{-7} ... 10^{-6} Msun/yr. In particular, we show that, if the effects of rotation are properly considered, helium shell sources are significantly stabilized, which might increase the likelihood for accreting white dwarfs to grow to the Chandrasekhar limit.

description: Using the evolution history of the universe, one can make constraint on the parameter space of dynamic dark energy models. We discuss two different parameterized dark energy models. Our results further restrict the combined constraints obtained from supernova and WMAP observations. From the allowed parameter space, it is found that our universe will experience an eternal acceleration. We also estimate the bound on the physically relevant regions both in the re-inflationary and inflationary phases.

description: In the 1990's, urban demand for housing land around city-agglomerations increased rapidly. Additionally, the decreasing profitability of agricultural production caused farmers, who are able to freely decide on land turnover, to be interested in land sale for non-agricultural purposes. At the same time, Polish counties received the status of self-governments, which then imposed their will upon local economic development. In this way, counties became responsible for land management as well, and started supporting the process of land conversion, perceived as a factor of the above development. Such implications have created the following situation: decentralisation and the extension of private control over land has led to the loss of rural landscapes in Poland, because farmers, county self-governments and rural society in general gain from the conversion of agricultural to housing land. Therefore, field research has been exercised at the county level. For the investigation, two counties, located in regions differentiated by economic growth, were selected. The data were collected through the collection of archival records, documentation review and semi-structured interviews.

description: We present a new experimental method for measuring inner-shell ionization cross sections of low-charged ions colliding with hydrogen gas target in a storage ring. The method is based on a calibration by the well-known differential cross sections of proton elastic scattering on nuclei. $K$-shell ionization cross section of 1047(100) barn for the 95 MeV/u $^{58}$Ni$^{19+}$ ions colliding with hydrogen atoms was obtained in this work. Compared to the measured ionization cross section, a good agreement is achieved with the prediction by the Relativistic Ionization CODE Modified program (RICODE-M).
SUSTAINABLE AGRICULTURE - GETTING THE INSTITUTIONS RIGHT

description: In most countries of the world, a sustainable agriculture is both an important and difficult issue. The agricultural sector in Central and Eastern European is confronted by two large problems at the same time: transition processes and sustainability. The purpose of this paper is, in the first place, to make clear that the institutional setting is very important. Second, it gives an overview of the literature on sustainability, institutions and institutional innovation. The phenomenon sustainability encompassing three dimensions: economic, social and environmental. Institutions are not always exogenous and right so that economic agents will behave in the 'correct' (that is efficient) manner. The non-marketable attributes of agricultural land use such as wildlife and landscape and the quality of soil, water and air create market failure. However, they are important for sustainability. With a lack of markets to realise sustainability, there is a strong incentive to develop institutions capable of changing the farmer's behaviour in ways that will achieve the unachievable via market signals alone. Direct government production is likely to be superior, if the government may not know what it wants and if the contract party has a strong tendency to reduce costs, but this is accompanied by a reduction in (non-contractable) quality. However, in general, both situations do not apply to sustainable agriculture. Type of government intervention has consequence for property rights. Under influence of changes in the institutional environment, the opinion about the protection of the property rights is shifting. The economic valuation of changes in the quality of soil, water, wildlife and landscape depends on if the change taking place either below or above the reference level. From the actual behaviour of the government, it can be concluded that the reference level is being used more and more as a watershed to the question of the allocation of property rights and the use of charges or compensation.

description: The aim of this paper is to develop a comprehensive conceptual framework for the analysis of institutions, policies and farming systems for agri-environmental sustainability in Central and Eastern European countries in transition. The basic unit of analysis is the 'agri-environmental action scenario'. The action scenario consists of a set of components which together shape the outcomes of an agri-environmental action situation. The framework consists of 1) the environmental effects of transition, 2) policies, 3) institutions, and 4) farming systems. We aim at characterising these key elements of the framework, their relationship and interactions, and their role in achieving sustainability at the interface between agriculture and the environment. Environmental areas of concern are: water, soil and biodiversity. The paper intends to create a common understanding of basic concepts and a shared conceptual model among the members of the Central and Eastern European Sustainable Agriculture (CEESA) Network. The framework will be adapted according to new insights and findings during the course of research activities of the CEESA research project.

description: This paper aims at explaining the role and importance of the evolution of institutions for sustainable agri-environments during the transition process by referring to examples of agri-environmental problems faced in Central and Eastern European countries. It is often stated that the replacement of institutional structures in post socialist countries would bring a unique opportunity to implement new policies and institutions needed to ensure that economic growth is environmentally sustainable. This idea stems from the assumption that the breakdown of the socialist system resembles that (of the Schumpeterian type) of creative destruction - a process that incessantly revolutionizes economic structures from within. However, not all kinds of institutions, especially at local level, can simply be implemented, and even more, not incessantly. Instead, they evolve as a response to ecosystem and social system characteristics, and this is a rather slow process. A central question therefore is whether the required institutional arrangements for achieving sustainability in the area of agri-environmental resource management can be built more easily in periods of transition as they fill institutional gaps, or whether processes of transition make institution building a more difficult and far more time consuming task than previously thought. Above all, we want to find out, how these two processes of institution building at different scales affect the sustainable management of resources such as water and biodiversity in agriculture? It will become clear that the agri-environmental problem areas faced during transition are complex and dynamic and require adequate institutions both by political design and from the grassroots, to be developed by the respective actors involved. Transition from centrally planned to pluralistic systems has to be considered as a particular and in some respect non-typical process of institutional change. Popular theories of institutional change do not necessarily apply. The privatisation experience from many CEE countries will serve as an example. Finally, we will provide some examples of missing or insufficient interaction between political actors or agencies and people in CEE countries. Substantial investments into social and human capital, particularly regarding informal institutions are needed for institutions of sustainability to evolve.

description: Let $β\equivβ^{(2n)}$ be an N-dimensional real multi-sequence of degree 2n, with associated moment matrix $\mathcal{M}(n)\equiv \mathcal{M}(n)(β)$, and let $r:=rank \mathcal{M}(n)$. We prove that if $\mathcal{M}(n)$ is positive semidefinite and admits a rank-preserving moment matrix extension $\mathcal{M}(n+1)$, then $\mathcal{M}(n+1)$ has a unique representing measure μ, which is r-atomic, with supp μ$ equal to $\mathcal{V}(\mathcal{M}(n+1))$, the algebraic variety of $\mathcal{M}(n+1)$. Further, βhas an r-atomic (minimal) representing measure supported in a semi-algebraic set $K_{\mathcal{Q}}$ subordinate to a family $\mathcal{Q}% \equiv\{q_{i}\}_{i=1}^{m}\subseteq\mathbb{R}[t_{1},...,t_{N}]$ if and only if $\mathcal{M}(n)$ is positive semidefinite and admits a rank-preserving extension $\mathcal{M}(n+1)$ for which the associated localizing matrices $\mathcal{M}_{q_{i}}(n+[\frac{1+°q_{i}}{2}])$ are positive semidefinite $(1\leq i\leq m)$; in this case, μ(as above) satisfies supp μ\subseteq K_{\mathcal{Q}}$, and μhas precisely rank \mathcal{M}(n)-rank \mathcal{M}_{q_{i}}(n+[\frac{1+°q_{i}}{2}])$ atoms in $\mathcal{Z}(q_{i})\equiv {t\in\mathbb{R}^{N}:q_{i}(t)=0}$, $1\leq i\leq m$.
