Correlation between moral obligation and pro-environmentality in the school population of the rural area of Quindío-Colombia
Objective: determine the relationship between moral obligation and pro-environmentality in students from a rural locality in Colombia.Method: An investigation was carried out with a cross-sectional and correlational-type quantitative approach.Through a convenience sampling and complying with the established selection criteria, young adolescents enrolled in grades eight through eleven were included. The validated Likert-type scale of environmental attitudes towards specific problems was applied. The analysis of the information was carried out in the SPSS program (Version 23); Absolute frequencies and percentages are presented for qualitative variables, as well as mean/median and standard deviation/interquartile range for variables of a quantitative nature. Correlation analysis was performed with Spearman's test. Results: a total of 274 adolescents were included, average age 14 years, 53.3% men and 39.8% in eighth grade. 83.9% stated that they take care of the environment. A relationship was found between moral obligation and social norm (Rho: 0.43; p ≤ 0.0001) but not between them and environmental awareness (p > 0.05). The results show that ecological knowledge as an institutionalized teaching is not related to moral obligation. Conclusion: The research showed the moral obligation and the social norm are in line with pro-environmental conduct. A multidimensional approach is suggested to explain the moral and pro-environmental obligation.Objetivo: determinar la relación entre la obligación moral y proambientalidad en estudiantes de una localidad rural en Colombia. Materiales y método: se realizó una investigación con enfoque cuantitativo de corte transversal y de tipo correlacional. Mediante un muestreo a conveniencia y cumpliendo con los criterios de selección establecidos, se incluyeron jóvenes adolescentes escolarizados en los grados octavo a undécimo. Se aplicó la escala validada de actitudes ambientales hacia problemas específicos de tipo Likert. El análisis de la información se realizó en el programa SPSS (Versión 23); se presentan frecuencias absolutas y porcentajes para variables cualitativas, así como promedio/mediana y desviación estándar/rango intercuartílico para las variables de naturaleza cuantitativa. El análisis de correlación se realizó con la prueba de Spearman. Resultados: en total 274 adolescentes fueron incluidos, edad promedio de 14 años, el 53,3% hombres y 39,8% de octavo grado. El 83,9% manifestó que cuida del medio ambiente. Se encontró una relación entre la obligación moral y la norma social (Rho: 0,43; p ≤ 0,0001) pero no entre ellas y la conciencia ambiental (p > 0,05). Los resultados muestran que el conocimiento ecológico como una enseñanza institucionalizada no está en relación con la obligación moral. Conclusión: la obligación moral y la norma social están en consonancia con la conducta proambiental. Se sugiere un abordaje multidimensional para explicar la obligación moral y proambientalidad
The role of neo-tectonics in the sedimentary infilling and geomorphological evolution of the Guadalquivir estuary (Gulf of Cadiz, SW Spain) during the Holocene.
Spain) has yielded new evidence regarding the sedimentary infilling and geomorphological evolution of the Guadalquivir estuary during the Holocene. The sedimentation and geomorphological disposition have been strongly conditioned by neotectonic activity along a set of SW-NE alignments, interrupted by other alignments that follow E-W and NW-SE directions. The most conspicuous of the SW-NE alignments is the Torre Carbonero-Marilópez Fault (TCMF). South of this fault, the estuary experienced a marked subsidence from about 4000 to 2000 cal. yr BP through a series of sedimentary sequences of retrogradation and aggradationwithin the context of relative sea-level rise. From c. 2000 cal. yr BP to the present the subsidence has remained relatively dormant, with progradation of the littoral systems and infilling of the marshland progressing within a context of sea-level stability. Our results reveal that neotectonic activity is a critical factor thatmust also be reckonedwith in any attempt to understand the Holocene geomorphological evolution in the Guadalquivir estuary
Descripción e interpretación geológica de las islas de providencia y santa catalina
Las islas de Providencia y Santa Catalina hacen parte del Departamento Archipiélago de San Andrés, Providencia y Santa Catalina, localizado en la cuenca Los Cayos en el Mar Caribe, al Noroeste de Colombia. Geológicamente las islas se ubican en el Rise de Nicaragua Inferior entre la Fractura de Pedro y el Escarpe de Hess (Rogers et al, 2007). Estas islas están conformadas principalmente por rocas volcánicas de carácter alcalino y calco-alcalino de edad mioceno medio y plioceno respectivamente. Se propone que la evolución geotectónica de la región parte de dos conos volcánicos erosionados cuya historia geológica está íntimamente relacionada con la evolución del Rise de Nicaragua y parte de la Placa Caribe (Rogers et al, 2007; Pindell y Kennan, 2001; Geister y Díaz, 2002). A la isla se le asocian unidades geomorfológicas de costas elevadas y bajas y en ella ocurren procesos morfodinámicos como caída de bloques, deslizamientos y erosión costera que podrían poner en riesgo la población. Económicamente se presenta explotación informal de canteras para agregados y existe la posibilidad de almacenamiento de hidrocarburos en la cuenca Los Cayos
Payment Systems Report - June of 2020
With its annual Payment Systems Report, Banco de la República offers a complete overview of the infrastructure of Colombia’s financial market. Each edition of the report has four objectives: 1) to publicize a consolidated account of how the figures for payment infrastructures have evolved with respect to both financial assets and goods and services; 2) to summarize the issues that are being debated internationally and are of interest to the industry that provides payment clearing and settlement services; 3) to offer the public an explanation of the ideas and concepts behind retail-value payment processes and the trends in retail payments within the circuit of individuals and companies; and 4) to familiarize the public, the industry, and all other financial authorities with the methodological progress that has been achieved through applied research to analyze the stability of payment systems. This edition introduces changes that have been made in the structure of the report, which are intended to make it easier and more enjoyable to read.
The initial sections in this edition, which is the eleventh, contain an analysis of the statistics on the evolution and performance of financial market infrastructures. These are understood as multilateral systems wherein the participating entities clear, settle and register payments, securities, derivatives and other financial assets.
The large-value payment system (CUD) saw less momentum in 2019 than it did the year before, mainly because of a decline in the amount of secondary market operations for government bonds, both in cash and sell/buy-backs, which was offset by an increase in operations with collective investment funds (CIFs) and Banco de la República’s operations to increase the money supply (repos). Consequently, the Central Securities Depository (DCV) registered less activity, due to fewer negotiations on the secondary market for public debt. This trend was also observed in the private debt market, as evidenced by the decline in the average amounts cleared and settled through the Central Securities Depository of Colombia (Deceval) and in the value of operations with financial derivatives cleared and settled through the Central Counterparty of Colombia (CRCC).
Section three offers a comprehensive look at the market for retail-value payments; that is, transactions made by individuals and companies. During 2019, electronic transfers increased, and payments made with debit and credit cards continued to trend upward. In contrast, payments by check continued to decline, although the average daily value was almost four times the value of debit and credit card purchases.
The same section contains the results of the fourth survey on how the use of retail-value payment instruments (for usual payments) is perceived. Conducted at the end of 2019, the main purpose of the survey was to identify the availability of these payment instruments, the public’s preferences for them, and their acceptance by merchants. It is worth noting that cash continues to be the instrument most used by the population for usual monthly payments (88.1% with respect to the number of payments and 87.4% in value). However, its use in terms of value has declined, having registered 89.6% in the 2017 survey. In turn, the level of acceptance by merchants of payment instruments other than cash is 14.1% for debit cards, 13.4% for credit cards, 8.2% for electronic transfers of funds and 1.8% for checks. The main reason for the use of cash is the absence of point-of-sale terminals at commercial establishments.
Considering that the retail-payment market worldwide is influenced by constant innovation in payment services, by the modernization of clearing and settlement systems, and by the efforts of regulators to redefine the payment industry for the future, these trends are addressed in the fourth section of the report. There is an account of how innovations in technology-based financial payment services have developed, and it shows that while this topic is not new, it has evolved, particularly in terms of origin and vocation. One of the boxes that accompanies the fourth section deals with certain payment aspects of open banking and international experience in that regard, which has given the customers of a financial entity sovereignty over their data, allowing them, under transparent and secure conditions, to authorize a third party, other than their financial entity, to request information on their accounts with financial entities, thus enabling the third party to offer various financial services or initiate payments. Innovation also has sparked interest among international organizations, central banks, and research groups concerning the creation of digital currencies. Accordingly, the last box deals with the recent international debate on issuance of central bank digital currencies.
In terms of the methodological progress that has been made, it is important to underscore the work that has been done on the role of central counterparties (CCPs) in mitigating liquidity and counterparty risk. The fifth section of the report offers an explanation of a document in which the work of CCPs in financial markets is analyzed and corroborated through an exercise that was built around the Central Counterparty of Colombia (CRCC) in the Colombian market for non-delivery peso-dollar forward exchange transactions, using the methodology of network topology. The results provide empirical support for the different theoretical models developed to study the effect of CCPs on financial markets.
Finally, the results of research using artificial intelligence with information from the large-value payment system are presented. Based on the payments made among financial institutions in the large-value payment system, a methodology is used to compare different payment networks, as well as to determine which ones can be considered abnormal. The methodology shows signs that indicate when a network moves away from its historical trend, so it can be studied and monitored. A methodology similar to the one applied to classify images is used to make this comparison, the idea being to extract the main characteristics of the networks and use them as a parameter for comparison.

Mucosal Immune Defence Gene Polymorphisms as Relevant Players in the Pathogenesis of IgA Vasculitis?
ITGAM–ITGAX (rs11150612, rs11574637), VAV3 rs17019602, CARD9 rs4077515, DEFA (rs2738048, rs10086568), and HORMAD2 rs2412971 are mucosal immune defence polymorphisms, that have an impact on IgA production, described as risk loci for IgA nephropathy (IgAN). Since IgAN and Immunoglobulin-A vasculitis (IgAV) share molecular mechanisms, with the aberrant deposit of IgA1 being the main pathophysiologic feature of both entities, we assessed the potential influence of the seven abovementioned polymorphisms on IgAV pathogenesis. These seven variants were genotyped in 381 Caucasian IgAV patients and 997 matched healthy controls. No statistically significant differences were observed in the genotype and allele frequencies of these seven polymorphisms when the whole cohort of IgAV patients and those with nephritis were compared to controls. Similar genotype and allele frequencies of all polymorphisms were disclosed when IgAV patients were stratified according to the age at disease onset or the presence/absence of gastrointestinal or renal manifestations. Likewise, no ITGAM–ITGAX and DEFA haplotype differences were observed when the whole cohort of IgAV patients, along with those with nephritis and controls, as well as IgAV patients, stratified according to the abovementioned clinical characteristics, were compared. Our results suggest that mucosal immune defence polymorphisms do not represent novel genetic risk factors for IgAV pathogenesis
Clinical Characteristics and Outcomes of Patients with Heart Failure of Hypertensive Etiology: Analysis of Colombian Heart Failure Registry (RECOLFACA)
Introduction: Arterial hypertension represents one of the main comorbidities observed in patients with heart failure (HF) and one of the main risk factors for its development. Despite this, studies assessing this hypertensive etiology are scarce in Latin America. Our objective was to analyze the prevalence of HF of hypertensive etiology and evaluate its prognosis in patients enrolled in the Colombian Heart Failure Registry (RECOLFACA by its Spanish acronym). Methods: RECOLFACA recruited adult patients diagnosed with HF in 60 centers in Colombia between 2017 and 2019. The primary outcome was all-cause mortality. A Cox proportional hazards regression model was used to assess factors associated with primary outcomes in patients with hypertensive HF. A p value <0.05 was considered significant. All statistical tests were two-tailed. Results: Out of the total number of patients evaluated in RECOLFACA (n = 2,514), 804 had a diagnosis of HF with hypertensive etiology (31.9%). These patients were less frequently males and had a significantly older age and lower prevalence of comorbidities than those with HF of other etiologies. Additionally, patients with hypertensive HF had a higher prevalence of HF with preserved ejection fraction (HFpEF) (34.1% vs. 28.3%; p = 0.004). Finally, type 2 diabetes mellitus, chronic obstructive pulmonary disease diagnosis, and NYHA class IV were classified as independent mortality risk factors. Conclusions: Hypertensive HF represents about one-third of the total number of patients with HF in RECOLFACA. Compared with HF of other etiologies, it presents a differential clinical profile – older age and a higher prevalence of HFpEF. RECOLFACA has become a useful tool to characterize patients with HF in Colombia, with which it has been possible to carry out a more specific search and reach the diagnosis of this pathology in our population, and it has served as an example to stimulate registries of patients with HF in other countries in the region

PDGF-BB serum levels are decreased in adult onset Pompe patients
Adult onset Pompe disease is a genetic disorder characterized by slowly progressive skeletal and respiratory muscle weakness. Symptomatic patients are treated with enzymatic replacement therapy with human recombinant alfa glucosidase. Motor functional tests and spirometry are commonly used to follow patients up. However, a serological biomarker that correlates with the progression of the disease could improve follow-up. We studied serum concentrations of TGFβ, PDGF-BB, PDGF-AA and CTGF growth factors in 37 adult onset Pompe patients and 45 controls. Moreover, all patients performed several muscle function tests, conventional spirometry, and quantitative muscle MRI using 3-point Dixon. We observed a statistically significant change in the serum concentration of each growth factor in patients compared to controls. However, only PDGF-BB levels were able to differentiate between asymptomatic and symptomatic patients, suggesting its potential role in the follow-up of asymptomatic patients. Moreover, our results point to a dysregulation of muscle regeneration as an additional pathomechanism of Pompe disease

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism
Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio
