Abstract A survey of the literature on the economics of natural resources. Extractive resources are classified as renewable or non-renewable, depending on whether they exhibit economically significant rates of regeneration. A unified model of optimal extraction over time is developed, drawing on a number of contributions to the literature. Special features are developed for the renewable and non-renewable cases, and extensions and applications are noted, as well as needs for further research. Policy issues are treated, chief among these being the extent to which the market can be trusted to generate the right rate of extraction. Finally the empirical evidence is reviewed on whether we are running out of extractive resources.

La psicología de la sustentabilidad estriba en la predicción de un comportamiento que, por sus dimensiones y determinantes, se ha identificado como factor de sustentabilidad. En este sentido, este trabajo pretende discutir el proceso sociohistórico en el que se ha desarrollado el constructo del comportamiento sustentable, más a partir de evidencias empíricas que de debates teóricos, conceptuales, metodológicos o estadísticos. Este ejercicio llama la atención acerca de la participación deliberativa de la comunidad y se inscribe en el debate sobre la relación entre sociedad y Estado con respecto a la conservación de los recursos naturales mediante los servicios públicos, municipales y residenciales. En este tenor, la revisión de los hallazgos extraídos del contraste de modelos de medición en referencia a modelos estructurales supone no sólo la especificación de relaciones de dependencia, sino su discusión, dado que fueron importados de disciplinas tales como la pedagogía, la economía, la sociología o la antropología para incorporarlos en los modelos predictivos del comportamiento sustentable.Palabras clave: Recursos naturales, Servicios públicos, Psicología de la sustentabilidad, Comportamiento sustentable, Modelos estructurales Theory of sustainable behavior for local developmentSummaryThe psychology of sustainability is based on the prediction of a behavior that, due to its dimensions and determinants, has been identified as a sustainability factor. In this sense, this work aims to discuss the sociohistorical process in which the construct of sustainable behavior has been developed, more from empirical evidence than from theoretical, conceptual, methodological or statistical debates. This exercise draws attention to the deliberative participation of the community and is part of the debate about the relationship between society and the State with respect to the conservation of natural resources through public, municipal and residential services. In this sense, the review of the findings extracted from the contrast of measurement models in reference to structural models supposes not only the specification of dependency relations, but their discussion, given that they were imported from disciplines such as pedagogy, economics, sociology or anthropology to incorporate them into predictive models of sustainable behavior.Keywords: Natural resources, Public services, Sustainability psychology, Sustainable behavior, Structural models. Théorie du comportement pour le développement durable au niveau localRésuméLa psychologie du développement durable réside dans la prédiction d’un comportement qui, par ses dimensions et déterminations, a été identifié comme un facteur en faveur de ce développement.

Based on the case study of ECCAS’s member states, this study raises a series of problems which can be linked to the highly theoretical problematic of the relationship between international investment law and the regional law, two autonomous normative systems which pursue different objectives on the basis of international law standard that binds different parties. This study proposes short, medium and long term legal solutions which can be used by states to restore their sovereignty over their natural resources, in particular by indicating to them how to cancel the excessive tax expenditure granted to investors in establishment conventions and how to overcome stabilisation clauses inserted in these same state’s contracts. These measures are particularly useful in protecting states from possible legal consequences of measures taken in the context of the fight against the pandemic of the new corona virus. Finally, this study contains many proposals relating to the reform of investment law applicable to Africa, such as regionalism which would facilitate the generalisation of the right to regulate in the general interest. À partir du cas des États membres de la CEMAC, cette étude soulève une série de problèmes que l›on peut rattacher à la problématique éminemment théorique des rapports de système entre le Droit international des investissements et le Droit communautaire, deux systèmes normatifs autonomes qui poursuivent des objectifs différents sur le fondement de normes internationales liant des parties distinctes. Elle permet d’offrir aux États des solutions juridiques utilisables à court, à moyen et à long terme pour restaurer leur souveraineté sur leurs ressources naturelles, notamment en leur indiquant comment revenir sur les dépenses fiscales excessives accordées aux investisseurs dans les conventions d’établissement et comment faire échec aux clauses de stabilisation insérées dans ces mêmes Contrats d’État. Ces mesures s’avèrent particulièrement utiles pour protéger les États des éventuelles conséquences juridiques des mesures prises dans le cadre de la lutte contre la pandémie du nouveau Corona virus. Cette étude renferme enfin de nombreuses propositions relatives à la réforme du Droit des investissements applicable en Afrique, parmi lesquelles celle du régionalisme qui faciliterait la généralisation du Droit de règlementer dans l’intérêt général.

Indonesia is one of many countries in the world so called resource-rich country. Natural resources abundance needs to be managed in the right way in order to avoid dutch diseases and resources curses. These two phenomena generally happened in the country, which has abundant natural resources. Learned from Norwegian experiences, Indonesian Government need to focus its policy to prevent rent seeking activities. The literature study presented in this paper is aimed to provide important insight for government entities in focusing their policies and programs to avoid resources curse. From the internal audit perspective, this study is expected to improve internal audit’s role in assurance and consulting.

El autoritarismo es un constructo ampliamente estudiado en psicología para investigar comportamientos políticos. Para su medición se suele usar la escala de autoritarismo de derechas (RWA), la cual tiene variaciones en sus propiedades psicométricas según cada contexto. En este artículo traducimos y adaptamos una versión reducida del autoritarismo de derechas al contexto colombiano. En dos estudios (NEstudio1=417;NEstudio2=396), identificamos tres dimensiones: agresión-autoritaria, sumisión-autoritaria y convencionalismo; y encontramos que la RWA estuvo asociada positivamente con: dominancia social, deshumanización del adversario, apoyo al conflicto, patriotismo, sexismo, homofobia y la prohibición de políticas sociales consideradas como liberales (e.g., aborto, matrimonio igualitario, eutanasia). Se aporta evidencia empírica a favor de las propiedades psicométricas de la escala de RWA en el contexto colombiano. Authoritarianism is widely used construct to study political behaviors.For its measurement, researchers usually use the right authoritarianism scale (RWA), which has variations in its psychometric properties according to each context. In this article we translate and adapt a reduced version of RWA to the Colombian context. In two studies (NStudy1=417; NStudy2=396), we identified three dimensions: authoritarian-aggression, authoritarian-submission,and conventionalism. We also found that RWA was positively associated with: social dominance, dehumanization of the adversary, support for conflict, patriotism, sexism, homophobia and the prohibition of social policies considered liberal (e.g., abortion, equal marriage, euthanasia). Empirical evidence is provided in favor of the psychometric properties of the RWA scale in the Colombian context

This chapter analyzes media malaise theories and their consequences for legitimacy. These theories argue that the increasing availability of information through new and old media and increasingly negative tone of media are to blame for declining legitimacy. The chapter examines these claims by providing a systematic review of empirical research on media and political support. It first investigates whether news coverage has become more negative over time, and then examines the micro process that might explain the link between media coverage and political support. Empirical evidence suggests that where coverage has become more negative, this occurred before the 1990s and has levelled off since, and is concentrated primarily in election news. Negative political news does have a modest impact on political support once controlled for level of education, but that effect can be positive and negative, depending on the medium, the receiver, and the indicator of political support.

The issue of sovereignty over natural resources has been a key element in the development of international law, notably leading to the emergence of the principle of States’ permanent sovereignty over their natural resources. However, concomitant to this focus on States’ sovereignty, international human rights law proclaims the right of peoples to self-determination over their natural resources. This has led to a complex and ambivalent relationship between the principle of States’ sovereignty over natural resources and peoples’ rights to natural resources. This chapter analyses this conflicting relationship and examines the emergence of the right of peoples to freely dispose of their natural resources and evaluates its potential role in contemporary advocacy. It notably explores how indigenous peoples have called for the revival of their right to sovereignty over natural resources, and how the global peasants’ movement has pushed for the recognition of the concept of food sovereignty.

AbstractEcological factors, such as predation, have traditionally been used to explain sociability. However, it is increasingly recognised that individuals within a group do not associate randomly, and that these non-random associations can generate fitness advantages. The majority of the empirical evidence on differentiated associations in group-living mammals, however, comes from a limited number of taxa and we still know very little about their occurrence and characteristics in some highly social species, such as rats (Rattus spp.). Here, using network analysis, we quantified association patterns in four groups of male fancy rats. We found that the associations between rats were not randomly distributed and that most individuals had significantly more preferred/avoided associates than expected by random. We also found that these preferences can be stable over time, and that they were not influenced by individuals’ rank position in the dominance hierarchy. Our findings are consistent with work in other mammals, but contrast with the limited evidence available for other rat strains. While further studies in groups with different demographic composition are warranted to confirm our findings, the occurrence of differentiated associations in all male groups of rats have important implications for the management and welfare of captive rat populations.

AbstractThis paper provides an account of the strategic control involved in skilled action. When I discuss strategic control, I have in mind the practical goals, plans, and strategies that skilled agents use in order to specify, structure, and organize their skilled actions, which they have learned through practice. The idea is that skilled agents are better than novices not only at implementing the intentions that they have but also at forming the right intentions. More specifically, skilled agents are able formulate and modify, adjust and adapt their practical intentions in ways that are appropriate, effective, and flexible given their overall goals. Further, to specify the kind of action plans that are involved in strategic control, I’ll rely on empirical evidence concerning mental practice and mental imagery from sports psychology as well as evidence highlighting the systematic differences in the cognitive representations of skills between experts and non-experts. I’ll claim that, together, this evidence suggests that the intentions that structure skilled actions are practical and not theoretical, that is, that they are perceptual and motor and not abstract, amodal, or linguistic. Importantly, despite their grounded nature, these plans are still personal-level, deliberate, rational states. That is, the practical intentions used to specify and structure skilled actions are best conceived of as higher-order, motor-modal structures, which can be manipulated and used by the agent for the purpose of reasoning, deliberation, decision-making and, of course, the actual online structuring and organizing of action.

Abstract Background Previous research in resting-state functional magnetic resonance imaging (rs-fMRI) has shown a mixed pattern of disrupted thalamocortical connectivity in psychosis. The clinical meaning of these findings and their stability over time remains unclear. We aimed to study thalamocortical connectivity longitudinally over a 1-year period in participants with recent-onset psychosis. Methods To this purpose, 129 individuals with recent-onset psychosis and 87 controls were clinically evaluated and scanned using rs-fMRI. Among them, 43 patients and 40 controls were re-scanned and re-evaluated 12 months later. Functional connectivity between the thalamus and the rest of the brain was calculated using a seed to voxel approach, and then compared between groups and correlated with clinical features cross-sectionally and longitudinally. Results At baseline, participants with recent-onset psychosis showed increased connectivity (compared to controls) between the thalamus and somatosensory and temporal regions (k = 653, T = 5.712), as well as decreased connectivity between the thalamus and left cerebellum and right prefrontal cortex (PFC; k = 201, T = −4.700). Longitudinal analyses revealed increased connectivity over time in recent-onset psychosis (relative to controls) in the right middle frontal gyrus. Conclusions Our results support the concept of abnormal thalamic connectivity as a core feature in psychosis. In agreement with a non-degenerative model of illness in which functional changes occur early in development and do not deteriorate over time, no evidence of progressive deterioration of connectivity during early psychosis was observed. Indeed, regionally increased connectivity between thalamus and PFC was observed.
