How does external debt and governance quality impact renewable energy consumption: novel policy insights from BRICS countries.

Amidst global environmental reforms, the role of energy systems is under scrutiny to promote ecological welfare through low-carbon alternatives. Amongst the solutions, the role of renewable energy as a clean source has become popular to mitigate climate change. However, the impact of debt on renewable energy consumption remains limited in the economic literature. The debt initiatives provide funding for environmental initiatives primarily, while it is also credited as a barrier to limiting the growth of clean energy programs. Within such discussion, the current study extended the dialogue by examining how external debt impacts energy transition in Brazil, Russia, India, China, and South Africa (BRICS) economies in the presence of institutional quality, education expenditures, and banking development. Using the novel CS-ARDL, AMG, and CCEMG tests, the study results showed that external debt decreases renewable energy consumption, while institutional quality, educational expenditures, banking developments, and economic growth are essential elements of green energy developments. Based on these conclusions, this study provides novel policy guidelines to align BRICS energy and economic agendas.

Efecto de la deuda económica sobre el bienestar psicológico de los residentes de cirugía: Resultados de un estudio nacional en Colombia / Effect of financial debt on the psychological well-being of surgery residents: Results of a national study in Colombia

Introducción. La deuda económica durante la residencia en cirugía general puede afectar el desempeño profesional, las decisiones de vida y el bienestar psicológico. La información disponible en Colombia es limitada. El objetivo de este estudio fue cuantificar la deuda económica del residente de cirugía general, identificar los factores asociados y evaluar su efecto en el bienestar psicológico. Métodos. Estudio de corte transversal analítico. Se invitó a 380 residentes a diligenciar una encuesta sobre los aspectos relacionados con su deuda económica y se utilizó el WHO-index para evaluar su bienestar psicológico. Resultados. Un total de 259 residentes participaron en el estudio (67,6 %). El 56 % posee una deuda económica promedio de COP $88.000.000 ((US$21.826)). Un alto nivel de endeudamiento se relacionó con el año de residencia, el tipo de institución (privada) y la solicitud de préstamos. Se identificó algún trastorno mental en 14,7 % y un bajo nivel de bienestar psicológico en 56,4 % de los participantes. No se identificó ninguna asociación entre una elevada deuda económica y el bajo bienestar psicológico. Conclusiones. La deuda económica tiene un efecto sobre los residentes. El endeudamiento de los residentes de cirugía en Colombia es altamente prevalente, y no se correlaciona con un pobre bienestar psicológico. La autodeterminación favorece el bienestar psicológico en el posgrado en cirugía general. Existe la necesidad de educación financiera en los residentes. Se requieren nuevos estudios que evalúen las causas del pobre bienestar psicológico.

Introduction. Financial debt during surgery residency can affect professional performance, life decisions, and psychological well-being. The information available in Colombia is limited. The objective of this study is to quantify the financial debt of the general surgery resident, identify the associated factors and evaluate their effect on psychological well-being. Methods. A cross-sectional study was carried out. A total of 380 residents were invited to complete a survey on aspects related to their financial debt, and the WHO-index to evaluate their psychological well-being. Results. A total of 259 residents participated in the study (67.6%). 56% have an average economic debt of $88,000,000 COP (US$21,826). High debt was related to level of residence, type of institution (private), and loan application. Some mental disorder was identified in 14.7% and a low level of psychological well-being in 56.4% of the participants. No association was identified between high financial debt and low psychological well-being. Conclusions. Economic debt has an effect on residents. Financial debt among surgical residents in Colombia is highly prevalent; however, it does not correlate with poor psychological well-being. Self-determination favors psychological well-being in the postgraduate course in general surgery. Likewise, the need for financial education in residents is imminent. New studies are required that thoroughly evaluate the causes of poor well-being.

Oxygen Debt as Predictor of Mortality and Multiple Organ Dysfunction Syndrome in Severe COVID-19 Patients: A Retrospective Study.

Background: Oxygen debt (DEOx) represents the disparity between resting and shock oxygen consumption (VO2) and is associated with metabolic insufficiency, acidosis, severity, and mortality. This study aimed to assess the reliability of DEOx as an indirect quantitative measure for predicting multiple organ dysfunction syndrome (MODS) and 28-day mortality in patients admitted to the intensive care unit (ICU) with respiratory syndrome severe acute coronavirus type 2 (SARS-CoV-2) infection, in comparison to the Acute Physiology and Chronic Health Evaluation II (APACHE II), sepsis-related organ failure assessment (SOFA), and 4C scores. Methods: A retrospective cohort study was conducted, including ICU patients with SARS-CoV-2 infection between 2020 and 2021. Clinical data were extracted from the EPIMED Monitor Database®. APACHE II, SOFA, and 4C scores were calculated upon ICU admission, and their accuracy in predicting 28-day mortality and MODS was compared to DEOx. Multivariate logistic regression analysis was performed to analyze the outcome variables. Results: 708 patients were included, with a mortality rate of 44.4%. DEOx value was 11.16 ml O2/kg. The mean age was 58.7 years. Multivariate analysis showed that DEOx was independently associated with mortality, intubation, and renal injury. Each point increase in creatinine was associated with a higher risk of MODS. To determine the precision of the scores, area under the receiver operating characteristic curves (AUROC) analysis was performed with weak discrimination and similar behavior for the primary outcomes. The most accurate scale for mortality and MODS was 4C with an AUC of 0.683 and APACHE II with an AUC of 0.814, while that of the AUROC of DEOx was 0.612 and 0.646, respectively. Conclusions: DEOx showed similar predictive value to established scoring systems in critically ill patients with SARS-CoV-2 infection. The correlation of DEOx with these scores may facilitate early intervention in critically ill patients.

Rethinking fiscal rules.

The Covid 19 pandemic has caused both a decrease in tax revenues and an increase in public spending, forcing governments to increase fiscal deficits to unprecedented levels. Given these circumstances, it is foreseeable that fiscal rules will play a predominant role in the design of many countries' recovery policies. We develop a general equilibrium, overlapping generations model for a small, open economy in order to study the impact of several fiscal rules upon welfare, public expenditures and growth. We calibrate the model to the Peruvian economy. In this economy, fiscal rules have been widely used and, unlike in other Latin American countries, they have been relatively successful. We find that fiscal rules will generate better results in terms of output if, in addition to maintaining control over the fiscal result, they also preserve public investment. We also find that the performance of economies that implement structural rules tends to be better than the performance of economies that implement rules based on realized budget balance.

Marine aquaculture as a source of propagules of invasive fouling species.

Non-indigenous species tend to colonize aquaculture installations, especially when they are near international ports. In addition to the local environmental hazard that colonizing non-indigenous species pose, they can also take advantage of local transport opportunities to spread elsewhere. In this study, we examined the risk of the spread of eight invasive fouling species that are found in mussel farms in southern Brazil. We used ensemble niche models based on worldwide occurrences of these species, and environmental variables (ocean temperature and salinity) to predict suitable areas for each species with three algorithms (Maxent, Random Forest, and Support Vector Machine). As a proxy for propagule pressure, we used the tonnage transported by container ships from Santa Catarina (the main mariculture region) that travel to other Brazilian ports. We found that ports in the tropical states of Pernambuco, Ceará, and Bahia received the largest tonnage, although far from Santa Catarina and in a different ecoregion. The ascidians Aplidium accarense and Didemnum perlucidum are known from Bahia, with a high risk of invasion in the other states. The bryozoan Watersipora subtorquata also has a high risk of establishment in Pernambuco, while the ascidian Botrylloides giganteus has a medium risk in Bahia. Paraná, a state in the same ecoregion as Santa Catarina is likely to be invaded by all species. A second state in this region, Rio Grande do Sul, is vulnerable to A. accarense, the barnacle Megabalanus coccopoma, and the mussel Mytilus galloprovincialis. Climate change is changing species latitudinal distributions and most species will gain rather than lose area in near future (by 2050). As an ideal habitat for fouling organisms and invasive species, aquaculture farms can increase propagule pressure and thus the probability that species will expand their distributions, especially if they are close to ports. Therefore, an integrated approach of the risks of both aquaculture and nautical transport equipment present in a region is necessary to better inform decision-making procedures aiming at the expansion or establishment of new aquaculture farms. The risk maps provided will allow authorities and regional stakeholders to prioritize areas of concern for mitigating the present and future spread of fouling species.

La importancia de la determinación de la deuda de oxígeno en el perioperatorio / The importance of oxygen debt determination in the perioperative period

Resumen: El fenómeno de la deuda de oxígeno (dO2) descrito hace varias décadas en el contexto del ejercicio físico se ha incorporado progresivamente al terreno de la medicina. En particular se ha utilizado durante los cambios hemodinámicos producidos por la cirugía y la anestesia en los pacientes de alto riesgo. La dO2 se definió como el aumento en la cantidad de oxígeno consumida por el organismo inmediatamente después de realizar un ejercicio físico hasta que el consumo se normaliza nuevamente. En el perioperatorio se llega a producir cuando se presenta un desbalance entre la oferta (DO2) y la demanda de oxígeno (VO2) que lleva a hipoxia tisular. El grado de la dO2 tisular se ha relacionado directamente con la falla de órganos múltiples y morbimortalidad perioperatoria. A pesar de los avances en la medicina, aún no es posible prevenir o disminuir la dO2 con la administración de líquidos o con el uso de agentes vasoactivos. Por lo que un retardo o manejo inadecuado de la hemodinámica perioperatoria producirá hipoperfusión e hipoxia tisular afectando los resultados de la cirugía. El conocimiento y la valoración de la dO2 es esencial durante la anestesia del paciente de alto riesgo. Para lograr este objetivo se requiere del uso de índices adecuados que permitan detectar y cuantificar la hipoperfusión tisular y el desbalance entre la DO2 y la VO2. En esta revisión se presentan los conceptos fundamentales de la dO2, su mecanismo, detección y cuantificación; además de las intervenciones para evitarla o disminuirla y las recomendaciones para los anestesiólogos con el fin de asegurar mejores resultados en los pacientes quirúrgicos de alto riesgo.

Abstract: The phenomenon of oxygen debt (dO2) described several decades ago in the context of physical exercise has been incorporated into medicine, particularly during the hemodynamic changes produced by surgery and anesthesia in high-risk patients. dO2 is defined as the increase in the amount of oxygen consumed by the body immediately after physical exercise until O2 consumption returns to normal. In the perioperative period, an imbalance between oxygen supply (DO2) and demand (VO2) could generate dO2. The degree of tissue dO2 has been directly related to multiple organ failure and perioperative morbimortality. Despite advances in medicine, it is not yet possible to prevent or lower the dO2 with fluid administration or vasoactive agents. Delay or inadequate management of hemodynamics could produce tissue hypoperfusion and hypoxia, affecting surgery outcomes. Knowledge and assessing dO2 during perioperative are essential during anesthesia for high-risk patients. Adequate indices are required to detect and quantify tissue hypoperfusion and the imbalance between DO2 and VO2 during anesthesia. This review presents the mechanism, detection, and quantification of dO2. In addition to interventions to avoid or reduce dO2 and recommendations for anesthesiologists to ensure better results in high-risk surgical patients.

Pursuing a Career in Pediatrics: Intersection of Educational Debt and Race/Ethnicity.

OBJECTIVES: To examine the associations among pediatric trainees' self-reported race/ethnicity, educational debt, and other factors for pursuing a pediatrics career. STUDY DESIGN: Cross-sectional study using data from the American Board of Pediatrics In-training Examination Post-examination Survey years 2018-2020 of categorical pediatric interns. Independent variable of interest was race/ethnicity. Classifications used were White, Hispanic/Latinx, Black/African American, Asian, and other/multiracial. The primary dependent variable was educational debt; secondary dependent variables included the importance of personal, professional, and financial factors in selecting a pediatric career. Means with 95% CIs were computed to summarize scores regarding a factor's importance. Chi-square tests of homogeneity and one-way ANOVA F tests were used to compare proportions and means of dependent variables across levels of self-reported race/ethnicity. RESULTS: A total of 11 150 (91.5%) completed the survey. Of the final analytical sample (7 943), approximately 6.3% self-identified as Black/African American, 8.2% as Hispanic/Latinx, 22% as Asian, and 55% as White; 44% reported >$200 000 of debt. Overall, 33% of those identifying as Black/African American had >$300 000 in educational debt. The highest ranked career factor was interest in a specific disease/patient population. The importance of educational debt in career choices was highest among those identifying as Black/African American, followed by Asians and Hispanic/Latinx. Among all races/ethnicities, the importance of mentorship decreased with higher educational debt. CONCLUSION: Among individuals pursuing pediatrics, the intersection of race/ethnicity and debt may influence trainees' pursuit of pediatric careers. Educational debt negatively impacts the importance of mentorship.

L'inconscient est politique / O inconsciente é a política: sobre as distopias na sociedade brasileira contemporânea / The unconscious is politics: about dystopias in contemporary brazilian society

RESUMO. A intenção deste ensaio é circunscrever na tradição social brasileira recente a problemática do populismo de extrema direita, em uma retomada e repetição do que se passou nos tempos nefastos da ditadura militar. Para isso, vamos destacar a dívida estabelecida pela sociedade brasileira para com os mortos, na medida em que os crimes realizados pela ditadura não foram julgados. Além disso, tal dívida remete a outras dívidas existentes na sociedade brasileira, referentes à tradição escravocrata, assim como as relações patriarcais no registro do gênero.

RESUME: L'intention de cet essai est de circonscrire dans la récente tradition sociale brésilienne la problématique du populisme d'extrême droite, dans une reprise et une répétition de ce qui s'est passé dans les temps néfastes de la dictature militaire. Pour cela, nous soulignerons la dette établie par la société brésilienne envers les morts, dans la mesure où les crimes perpétrés par la dictature n'ont pas été jugés. En outre, cette dette fait référence à d'autres dettes existant dans la société brésilienne, se référant à la tradition esclavagiste, ainsi qu'aux relations patriarcales dans le registre des sexes.

ABSTRACT. This essay intends to circumscribe in the recent Brazilian social tradition the problem of far right-wing populism, in a resumption and repetition of what happened in the nefarious times of the military dictatorship. For this, we analyzed the debt established by Brazilian society towards the dead, insofar as the crimes committed by the dictatorship were not judged. In addition, this debt refers to other existing debts in Brazilian society, referring to the slavery tradition, as well as gender related patriarchal relations.

La espiral de la deuda pública en Colombia (1990-2020) / The Public Debt Spiral in Colombia (1990-2020)

Resumen La deuda pública en Colombia entre el periodo de 1990 a 2020 se ha convertido en un eje estructurante de la economía política del país y bajo su manutención se ha generado un sin número de Leyes, Decretos y Normas que han determina do en gran parte las dinámicas de inversión y gasto social. Así mismo, se han su bordinado los derechos de la población colombiana a la estabilidad macroeco- nómica establecida bajo la teoría neoclásica. Si bien la deuda pública tiene una gran relevancia en la configuración del Estado en Colombia, los análisis sobre la problemática de la deuda pública y el servicio de esta es vago y no estructura la crisis fiscal del Estado con la del endeudamiento público, por lo cual en este artí culo se pretende evidenciar la configuración de la deuda pública en los últimos 30 años y su relación con la crisis fiscal del Estado.

Abstract The public debt in Colombia between 1990 and 2020 has become a structuring axis of the country's political economy and under its maintenance has generated a number of laws, decrees, and norms, which have largely determined the dyna mics of investment and social spending. Likewise, the rights of the Colombian population have been subordinated to the macroeconomic stability established under neoclassical theory. Although the public debt has a great relevance in the configuration of the State in Colombia, the analysis of the problem of public debt and its service is vague, and it does not structure the fiscal crisis of the Sta te with that of public indebtedness. Thus, this article aims to show the configu ration of the public debt in the last 30 years and its relationship with the fiscal crisis of the State.

Analysis of the economic effects on biopsychosocial homeostasis from a three-dimensional probability measurement system.

OBJECTIVE: Describes the economic effects on bio-psychosocial homeostasis from a three-dimensional analysis of the joint interaction of biological, psychological and economic-social comorbidities, in order to know the probabilities of occurrence of these conditions simultaneously. METHOD: It is a cross-sectional study and random quota sampling. 353 men and women over 20 years of age participated, and answered a 27 questions application (bio-psycho-economic-social), the data was analyzed three-dimensionally in order to know the probability of occurrence of the variables studied and their possible location in the probabilistic unit cube. RESULTS: Based on the unit cube proposal, it can be observed that in the block of people with incomes from 2200 to 6600 pesos in the group of men there is a probability of 12.9 per 1000 inhabitants of presenting debt problems, overweight and severe depression, while in the case of women, the probability is 2.08 per 1000 inhabitants. CONCLUSIONS: There is a priority axis that determines the change of the remaining variables, in this case it is the economic axis the one that determines the biological and psychological conditions.

OBJETIVO: Describir los efectos económicos en la homeostasis biopsicosocial a partir de un análisis tridimensional de la interacción conjunta de la comorbilidad biológica, psicológica y económico-social, con la finalidad de conocer las probabilidades de ocurrencia a partir de estas condiciones de forma simultánea. MÉTODO: Estudio transversal y muestreo aleatorio por cuotas. Participaron 353 hombres y mujeres mayores de 20 años que contestaron un cuestionario con 27 preguntas (biopsicosociales-económicas). Se analizaron los datos tridimensionalmente con la finalidad de conocer la probabilidad de ocurrencia de las variables estudiadas y su posible localización en el cubo unitario probabilístico. RESULTADOS: Con base en la propuesta del cubo unitario se obtiene que, en las personas con ingresos de 2200 a 6600 pesos, en los hombres existe una probabilidad de 12.9 por cada 1000 habitantes de presentar deudas, sobrepeso y depresión grave; en las mujeres, la probabilidad es de 2.08 por cada 1000 habitantes. CONCLUSIONES: Existe un eje prioritario que determina el cambio de las variables restantes, en este caso el eje económico que determina las condiciones biológicas y psicológicas.

Delving into the Determinants of Default Risk in Savings Groups: Empirical Evidence from Ecuador.

Financial inclusion has been broadly recognized as critical in alleviating poverty and achieving inclusive economic growth. The capability of borrowers to repay their microcredit loans is a critical concern and is the first risk of Microfinance institutions sustainability. Exploring the determinants of credit risk is an issue of substantial importance in microfinance. The purpose of this research was to identify the savings group members' characteristics that have impact on default risk. We have used a multivariate regression model to identify the factors that affect default behaviour among microcredit borrowers from savings groups. We have analysed a sample of more than different 400 Savings Groups and 7251 active users of the "Saving and Learning" program in Ecuador. Empirical results demonstrated that factors such as seniority, accumulated savings and the number of members in the savings groups are determinant variables of default risk. The significant positive sign on variable "Gender" is consistent with the previous authors that indicate that the probability of having problems in loan repayment is higher for males than for females. The generalizability of our findings should, of course, be interpreted with caution, as they may be idiosyncratic of the sample, period or region. To contrast and contextualize these results, we had in-depth discussions with the Savinco managers and their field agent in Ecuador. There are many contributions. For practitioners, relevant factors that can affect savings groups default rates have been identified. For academics, the rich information provided by the Savinco mobile App could be a starting point for further quantitative research.

Il est largement reconnu que l'inclusion financière est essentielle pour réduire la pauvreté et parvenir à une croissance économique inclusive. La capacité des emprunteurs à rembourser leurs prêts de microcrédit est une préoccupation essentielle et constitue le premier risque pour la pérennité des institutions de microfinance. L'étude des déterminants du risque de crédit est une question d'une importance capitale en microfinance. Le but de cette étude est d'identifier les caractéristiques des membres de groupes d'épargne qui ont un impact sur le risque de défaut de paiement. Nous avons utilisé un modèle de régression multivariée pour identifier les facteurs qui affectent le comportement de défaut de paiement parmi les emprunteurs de microcrédit au sein de groupes d'épargne. Nous avons analysé un échantillon de plus de 400 groupes d'épargne différents et 7 251 utilisateurs actifs du programme « Épargne et apprentissage ¼ en Équateur. Les résultats empiriques ont démontré que des facteurs tels que l'ancienneté, l'épargne accumulée et le nombre de membres dans les groupes d'épargne sont des variables déterminantes du risque de défaut de paiement. Sur la variable « Genre ¼, le signe positif significatif est cohérent avec les études précédentes qui indiquent que la probabilité d'avoir des problèmes de remboursement de prêt est plus élevée chez les hommes que chez les femmes. Bien entendu, le caractère généralisable de nos résultats doit être interprété avec prudence, car ces résultats peuvent être uniques à l'échantillon, à la période ou à la région. Pour contraster et contextualiser ces résultats, nous avons eu des discussions approfondies avec les gestionnaires de Savinco et leur agent de terrain en Équateur. Les contributions sont nombreuses. Pour les praticiens, ont été identifiés les facteurs pertinents pouvant affecter le taux de défaut de paiement des groupes d'épargne. Pour les universitaires, les riches informations fournies par l'application mobile Savinco pourraient être un point de départ pour d'autres études quantitatives.

Disaster, Debt, and 'Underdevelopment': The Cunning of Colonial-Capitalism in the Caribbean.

This article provides a critical overview of the structural forces exacerbating risk related to disasters in the Caribbean. It focuses on the historical antecedents and socio-environmental consequences of extreme weather events across the region via an anti-colonial analysis of Hurricanes Irma and Maria in 2017 and Dorian in 2019. The authors contend that the logics, practices and debts of colonial-capitalist development, neoliberal exploitation and post-independence corruption continue to reduce resilience and threaten public health in the region. They also detail the role that political economy and social geography play in the face of disasters. They end by proposing that future critiques of and solutions to vulnerability, disaster, and catastrophe in the Caribbean be more attentive to the historical trajectories of imperialism, debt and 'underdevelopment'.

Cognitive Abilities, Debt, Roads and their Impact on Deaths in Traffic in Brazil / Habilidades Cognitivas, Endividamento, Rodovias e seus Impactos nos Óbitos no Trânsito

Abstract Deaths in traffic represent a global and multicausal problem. We verified, through a linear regression model, that cognitive abilities (CA) and population indebtedness (PI) predict, together, 56% of the variation of death rates in the traffic (DT) of the twenty-seven states of Brazil. CA's are related to a greater control of the attention and, possibly, to a greater compliance with norms for preventing traffic accidents, has a greater impact than PI on DT, since PI associates to only one deficit of people's attention resources. The decrease of PI and the improvement of CA can decrease DT.

Resumo Os óbitos no trânsito representam um problema global e multicausal. Verificamos, por meio de um modelo de regressão linear, que as habilidades cognitivas (HC) e o endividamento populacional (ENDP), predizem, juntos, 56% da variação das taxas de óbitos no trânsito (TOT) das 27 unidades federativas (UF) do Brasil. As HC, por estarem relacionadas a um maior controle da atenção e, possivelmente, a um maior cumprimento de normas de prevenção contra acidentes de trânsito, possuem um impacto maior que o ENDP sobre as TOT, já que o ENDP associa somente a um deficit dos recursos de atenção das pessoas. A diminuição do ENDP e a melhoria das HC podem reduzir as TOT.

Deuda calórica en una cohorte de pacientes hospitalizados en unidades de cuidado intensivo / Caloric debt in a cohort of intensive care unit patients

El soporte nutricional que se brinda a los pacientes críticos, constituye para la mayoría la única vía de acceso a través de la cual es posible cubrir sus requerimientos nutricionales diarios. Sin embargo, se ha identificado que la presencia de deuda calórica impide cubrir dichos requerimientos. Este estudio determinó la deuda calórica y su potencial efecto clínico a través de una cohorte prospectiva que incluyó 191 pacientes que recibieron soporte nutricional en unidades de cuidado intensivo (UCI). Se evaluó la magnitud de la deuda calórica, los principales factores que la favorecen y se exploraron diferencias en desenlaces clínicos relacionados con mortalidad, complicaciones infecciosas y tiempo de estancia en UCI. Los resultados evidenciaron que la deuda calórica estuvo presente en el 73,8%(IC 95% = 67%-80%) de los pacientes evaluados; la principal causa estuvo relacionada con la interrupción de la nutrición enteral y no se encontró asociación entre el porcentaje de adecuación calórico y los desenlaces evaluados. Esta evaluación permitió establecer que la mayoría de los pacientes, a pesar de recibir soporte nutricional, se encuentran expuestos a deuda calórica siendo necesario generar estrategias de atención que permitan disminuir la exposición de esta población a dicha condición.

The nutritional support offered to critically ill patients is, for most of them, the only means to fulfill their daily nutritional requirements. However, it has been documented that nutritional support is not enough to cover such needs, due to the presence of caloric debt. We seek to determine the caloric debt and its potential to clinical affect critically ill patients that receive nutritional support in the Intensive Care Unit (ICU). We conducted a prospective cohort study with 191 patients. We assessed the magnitude of caloric debt and its related factors. We also explored variations in clinical outcomes related to mortality, infectious complications and ICU stay length. Caloric debt was found in 73.8% (95% CI = 67-80%) of patients who received less than 80% of their daily caloric requirements. Main causes were related to enteral nutrition interruption. We found no association between caloric debt and the evaluated outcomes. This evaluation made it possible to establish that the majority of patients, despite receiving nutritional support, were exposed to caloric debt, and it is necessary to generate care strategies to reduce the patients' exposure to this condition.

Revertir la memoria del conflicto armado colombiano, análisis del discurso en la prensa escrita / Reversing the memory of the Colombian armed conflict, analysis of discourse in the written press

Resumen Este artículo presenta los resultados de una investigación sobre los procesos de reversión de memorias del conflicto armado colombiano publicados en la prensa escrita. Se adopta la noción de memoria revertida como dispositivo narrativo mediante el que se relatan acontecimientos del pasado a partir de la cobertura de eventos actuales con valor noticioso en los medios de comunicación. Se empleó el método de Análisis del Discurso sobre notas de prensa referidas a los procesos de reparación a víctimas del conflicto, adelantados en el marco de las disposiciones de la Ley de Víctimas y Restitución de Tierras (2011) en Colombia. Dicha narrativa opera a través de diferentes portadores de memoria, entendidos como personas en las categorías de víctimas y victimarios; la reparación como fenómeno a través del que se paga una deuda histórica, por medio del reconocimiento y búsqueda de la verdad; y lugares donde se conmemoran los eventos, representados en museos. El análisis revela una narrativa en la que se concibe la memoria institucional del conflicto como rectificación del olvido ante el sufrimiento de las víctimas. Este desplazamiento discursivo configura un marco de posibilidad para el desarrollo de formas diferentes de relacionamiento entre las víctimas, el Estado y la sociedad en general, legitimando así el accionar del Estado como ente aglutinador y factor de cohesión nacional.

Abstract This paper aims to make a discourse analysis of the processes that reverse memories of the Colombian conflict in national newspapers. The research adopts a theoretical approach that describes reversed memory as a narratological device which tells past events while covers the present in news media. Methodology of discourse analysis on news pieces refered to the processes of reparation of victims was employed. These processes are being carried out in accordance with legal provisions stablished by Law of Victims and Land Restitution (2011). The analysis shows a narrative construction in which institutional memory of the conflict is conceived as a rectification on forgetting the victims' suffering. Such a narrative operates through memory carriers, which are understood as people under the name of victims and victimizers; reparation as a phenomenon through discursive forms such as payment of historical debt, acknowledgment of the victim and seeking of truth; and places represented as museums. This narrative process shapes an escenario in which development of new sorts of relations between victims, the State and society, legitimizing the State as a factor of national cohesion.

Money as a social relation beyond the state: a contribution to the institutionalist approach based on the Argentinian trueque.

This paper provides a contribution to the institutionalist approach to money through ethnographic research carried out in two local currency systems in Argentina (known as trueque). It argues that Argentinian local currencies must be considered as monies in their own right even if they differ from state and bank issued currencies, because they can be understood as systems of evaluation and settlement of debts denominated in a specific unit of account (the crédito). Money is said to be an ambivalent social relation because in the two cases studied it mediates very different dynamics, exacerbating inequality in one context and promoting collective emancipation in another. This difference is due to the kind of political communities that the crédito tends to forge. In both Rosario and Poriajhu, the political community is defined by a set of values that legitimizes ongoing monetary practices and institutions rather than the State's coercion.

La biopolítica de la deuda: relación acreedor-deudor / The biopolitics of debt: creditor-debtor relationship / A biopolítica da dívida: relação credor-devedor

Resumen El presente artículo propone un análisis de los dispositivos biopolíticos que se encuentran detrás de la figura del crédito o la deuda en el campo de la educación superior, a partir de una lectura histórica de la deuda y la relación acreedor-deudor en su interior, planteada esta como una relación de poder. Desde la comprensión de la deuda como un dispositivo de control biopolítico constitutivo del aparato neoliberal, esta se traslada al campo de la educación a través de la figura de crédito educativo, que está disponible a toda la población y facilita el acceso a la educación superior, y alimenta así un ideal de inversión a largo plazo con la promesa infinita de la conquista de un sujeto "empresario de sí mismo", que se encuentra en una procura permanente de recursos que le permitan mantener la inversión en sí mismo como aparato productivo. Así, este análisis consigue plantear el ideal del sujeto aparentemente independiente, que se sumerge en la deuda como mecanismo de acceso a los recursos que le acercan a la meta de ser "su propio jefe", como la esencia de uno de los engranajes principales en los modos de sujeción de la conducta, propios del neoliberalismo, y su mecanismo de la deuda, aplicados al campo de la educación. Sobre esta base tiene lugar una "pedagogía de la deuda" en la cual emergen como elementos indispensables en la fabricación de dicho sujeto la universidad y la educación superior.

Abstract This article proposes an analysis of the biopolitical devices that are behind the figure of credit or debt in the higher education field, based on a historical reading of the debt and the creditor-debtor relationship, explained as a relationship of power. From the understanding of the debt as a biopolitical constitutive device of control of the neoliberal apparatus, it is transferred to the field of education through the figure of educational credit, which is available to the entire population and facilitates access to higher education. And thus feeds an idea of long-term investment with the infinite promise of the conquest of a subject "entrepreneur of himself," who finds himself in a permanent pursuit of resources that allow him to maintain the investment in himself as a productive apparatus. Therefore, this analysis manages to pose the idea of the apparently independent subject, who immerses himself in the debt as a mechanism of access to resources that bring him closer to the goal of being "his own boss", as the essence of one of the main gears in modes of subjection of behavior, typical of neoliberalism, and its mechanism of debt, applied to the field of education. On this basis, there is a "debt pedagogy" in which the university and higher education emerge as indispensable elements in the manufacture of said subject.

Resumo O presente artigo propõe uma análise dos dispositivos biopolíticos que estão por trás da figura do crédito ou a dívida no campo do ensino superior, desde em uma leitura histórica da dívida e do relacionamento credor-devedor dentro dela, levantada ela como uma relação de poder. Desde a compreensão da dívida como um dispositivo de controle biopolítico constitutivo do aparelho neoliberal, esta é transferida para o campo da educação através da figura do crédito educacional, que está disponível para toda a população e facilita o acesso ao ensino superior, e assim alimenta um ideal de investimento em longo prazo com a infinita promessa da conquista de um sujeito "empresário de si mesmo", que se encontra em uma busca permanente de recursos que lhe permitam manter o investimento em si mesmo como um aparelho produtivo. Assim, esta análise consegue levantar o ideal do sujeito aparentemente independente, que se submerge na dívida como um mecanismo de acesso aos recursos que o aproximam ao objetivo de ser "seu próprio chefe", como a essência de uma das engrenagens principais nos modos de sujeição do comportamento, próprio do neoliberalismo, e seu mecanismo da dívida, aplicados ao campo da educação. Nesta base, tem lugar uma "pedagogia da dívida" na qual emergem como elementos indispensáveis na fabricação do referido sujeito à universidade e o ensino superior.

Threshold responses of Amazonian stream fishes to timing and extent of deforestation.

Deforestation is a primary driver of biodiversity change through habitat loss and fragmentation. Stream biodiversity may not respond to deforestation in a simple linear relationship. Rather, threshold responses to extent and timing of deforestation may occur. Identification of critical deforestation thresholds is needed for effective conservation and management. We tested for threshold responses of fish species and functional groups to degree of watershed and riparian zone deforestation and time since impact in 75 streams in the western Brazilian Amazon. We used remote sensing to assess deforestation from 1984 to 2011. Fish assemblages were sampled with seines and dip nets in a standardized manner. Fish species (n = 84) were classified into 20 functional groups based on ecomorphological traits associated with habitat use, feeding, and locomotion. Threshold responses were quantified using threshold indicator taxa analysis. Negative threshold responses to deforestation were common and consistently occurred at very low levels of deforestation (<20%) and soon after impact (<10 years). Sensitive species were functionally unique and associated with complex habitats and structures of allochthonous origin found in forested watersheds. Positive threshold responses of species were less common and generally occurred at >70% deforestation and >10 years after impact. Findings were similar at the community level for both taxonomic and functional analyses. Because most negative threshold responses occurred at low levels of deforestation and soon after impact, even minimal change is expected to negatively affect biodiversity. Delayed positive threshold responses to extreme deforestation by a few species do not offset the loss of sensitive taxa and likely contribute to biotic homogenization.

Waiting can be an optimal conservation strategy, even in a crisis discipline.

Biodiversity conservation projects confront immediate and escalating threats with limited funding. Conservation theory suggests that the best response to the species extinction crisis is to spend money as soon as it becomes available, and this is often an explicit constraint placed on funding. We use a general dynamic model of a conservation landscape to show that this decision to "front-load" project spending can be suboptimal if a delay allows managers to use resources more strategically. Our model demonstrates the existence of temporal efficiencies in conservation management, which parallel the spatial efficiencies identified by systematic conservation planning. The optimal timing of decisions balances the rate of biodiversity decline (e.g., the relaxation of extinction debts, or the progress of climate change) against the rate at which spending appreciates in value (e.g., through interest, learning, or capacity building). We contrast the benefits of acting and waiting in two ecosystems where restoration can mitigate forest bird extinction debts: South Australia's Mount Lofty Ranges and Paraguay's Atlantic Forest. In both cases, conservation outcomes cannot be maximized by front-loading spending, and the optimal solution recommends substantial delays before managers undertake conservation actions. Surprisingly, these delays allow superior conservation benefits to be achieved, in less time than front-loading. Our analyses provide an intuitive and mechanistic rationale for strategic delay, which contrasts with the orthodoxy of front-loaded spending for conservation actions. Our results illustrate the conservation efficiencies that could be achieved if decision makers choose when to spend their limited resources, as opposed to just where to spend them.
