Authors:   Universidad Popular del Cesar, Jiménez Lobo Dina Luz , Bracho Colina Erimar ,   Universidad Popular del Cesar
Published: January 2022

Este artículo tiene como propósito evaluar la presencia de riesgo moral en la estructura contractual de la producción de sal en Manaure – La Guajira, Colombia, dado que una situación de riesgo moral es una clase especial de problemas de información asimétrica en la que ésta surge después de celebrarse un contrato entre el principal y el agente; es decir, los inconvenientes del riesgo moral surgen del conflicto de intereses entre el principal y el agente. Teóricamente se refirieron autores como: Florez et al., (2015), Arévalo y Ojeda (2004), Lugo (2019); entre otros. Dentro de los aspectos metodológicos, se refiere a un tipo de investigación descriptiva bajo un enfoque mixto. Como técnica de recolección de datos se empleó la entrevista; la cual se aplicó a población objeto de estudio que fueron los miembros de cada una de las asociaciones que conforman SAMA Ltda (principal), y se emplearon a la vez técnicas cuantitativas para la recolección de la información. Para el análisis de los datos, por un lado se examinó la documentación y otras informaciones previas existente de Big Group (agente), suministradas por Galvis y Burbano, además se aplicó un modelo matemático de riesgo moral con asimetría de información, permitiendo obtener como resultados el poder demostrar cómo se pactaron los incentivos y los beneficios-utilizados de los actores involucrados a través de una restricción de compatibilidad de incentivos y de participación, dejando como conclusión final la presencia de una falla de mercado producto de una distorsión en la información, la cual se efectúa cuando el incentivo que logra percibir Big Group es suficiente para el logro del objetivo del principal (SAMA), lo que descarta la presencia de Riesgo Moral, pero deja en evidencia la asimetría de información de SAMA hacia el agente, lo que dificulto el desarrollo de sus actividades y llevo al declive de la empresa. Sus motivos se deben a querer tener un operador privado que aceptara las altas exigencias de las asociaciones sin ningún inconveniente, obviando la problemática sociocultural del territorio indígena y el monopolio de transportadores que a simple vista no presenta esta estructura, generando finalmente que el operador no lograra cumplir con los objetivos propuestos, resultando en perjuicio del agente y de la misma empresa contratista; SAMA. Finalmente, este proyecto surge por iniciativa propia como propuesta para la convocatoria de semilleros de investigación con recursos provenientes de la entidad que lo avale.

La seguridad alimentaria es un tema de interés a nivel mundial, asegurar la oferta de productos alimenticios no es una tarea fácil. Por lo que, el desarrollo de sistemas agroalimentarios eficientes con enfoque sustentable y sostenible, que permitan alcanzar la seguridad alimentaria son importantes, principalmente para aquella población ubicada en la clase baja y clase media; tal es el caso de la Agricultura Traspatio. Esta práctica agrícola permite la producción de baja escala a nivel casa habitación por medio de un huerto traspatio; enfocada a producir parte de los alimentos para consumo humano de los habitantes de dicha casa habitación, principalmente en zona marginadas. Este trabajo analiza el uso de los huertos familiares como práctica de autoalimento y desarrollo económico de familias marginadas. Por lo que el estudio, implicó una revisión literaria de los factores que influyen en la seguridad alimentaria, al mismo tiempo en que se analizó como la Agricultura Traspatio abona a garantizar la seguridad alimentaria (como cadena logística-corta); se realizó una revisión sistemática de trabajos que son reportados en la literatura de los últimos 5 años. Del estudio realizado, se desprende que son dos los factores que influyen significativamente en la producción de alimentos: por un lado (a) la dietética de la población está cambiando debido a las influencias de los grupos sociales; al mismo tiempo, en el que (b) el cambio climático genera estragos por los cambios abruptos en la variación global del clima del planeta; ocasionado e.g., temperaturas extremas, inundaciones, derretimiento de los polos, lluvias. Aunado a estos dos factores, un tercer factor atípico ha emergido como consecuencia de las medidas de distanciamiento de la emergencia sanitaria originada por el COVID-19 (c) la complejidad de adquirir alimentos sanos y frescos, derivado de las medidas del confinamiento voluntario, sana distancia y demás protocolos de seguridad sanitaria.
Relationship Between Crude Oil Price Fluctuations, Economic Growth, Inflation, and Exchange Rate in Indonesia 1967-2019
Authors: Nitami Salwinar Aprin , Hayati Banatul
Published: January 2022

Economic fluctuations can be caused by demand shocks and supply shocks. One of the supply shocks is caused by changes in world crude oil prices. As a net importer of crude oil, any change in crude oil prices makes domestic economic activity vulnerable to these shocks. The purpose of this study is to determine the effect of fluctuations in world crude oil prices on economic variables in Indonesia in the form of economic growth, inflation, and exchange rates. In addition, this study also analyzes the causal relationship between these variables. The type of data used is secondary data sourced from the BP Statistical Review of World Energy and the Worldbank. This research uses the VAR/VECM method, the research period was carried out during the years 1967-2019. The results showed that during 1967-2019 fluctuations in world crude oil prices had a significant positive effect on economic growth and had a significant negative effect on inflation and the exchange rate in the long run. Meanwhile, in the short term, world crude oil price fluctuations do not significantly affect economic growth, inflation, and the exchange rate. The results of the Granger causality show that there is no two-way causality relationship between variables.

Published: January 2022

Kapitalist üretim yapısının körüklediği rekabet, hayatın anlamını kariyer başarısı ve bunun sağladığı maddi doyumlara bağlamaktadır. Başarının zenginlik ile ölçüldüğü, başarısızlığın ise değersizlik ile eşitlendiği kapitalist sistem, tüm toplumsal kesimleri olumsuz etkilemektedir. Kişisel çıkara dayanan kazanımların kaybedilmemesi adına insani değerlerin ikinci plana atılmasına zemin hazırlayan kapitalist sistem, insanları acımasız bir rekabetin içine itmektedir. Çalışmanın anlamının değiştiği modern kapitalist toplumlarda başarının sahip olunan metalarla ölçülmesi, işsizliğin bir kimlik bunalımı olarak da algılanmasına yol açmaktadır. İşsiz kitlesinin giderek büyümesine yol açan mevcut üretim örgütlenmesi, kol, zihin ya da emek gücü ile çalışan mavi ya da beyaz yakalı çalışan herkesi tehdit etmektedir. Bu çalışmada, Costa-Gavras’ın Ölümcül Çözüm (2005) adlı filmi kapitalizm, rekabet ve beyaz yakalı işsizliği kavramları bağlamında analiz edilmiştir. Beyaz yakalı bir yöneticinin işsiz kalması sonrasında uğradığı maddi ve manevi yıkım ile içine düştüğü çaresizlikle rakiplerini öldürmeye başlamasını anlatan film, kapitalist rekabet koşullarının acımasızlığını da ortaya sermektedir. Çalışmada çözümleme için betimsel analiz ve göstergebilim yöntemleri birlikte kullanılmıştır. Kapitalist sistemin yetiştirdiği örnek bir beyaz yakalı çalışanın bile bir seri katile dönüşmesinin hikâyesini anlatan Ölümcül Çözüm filminin analizi, çalışan kesimlerin içinde bulunduğu iktisadi sistemin arka planını, mevcut ekonomik yapının neden olduğu psikolojik hezeyanları ve insanın kendi yarattığı sistem içerisinde geldiği acımasız ve parazitvari konumu tartışmaya açmaktadır.

Climate change is a major global challenge, which is complex, unpredictable and will continue at an increasingly fast rate, causing risks and great impacts on companies and the global economy. Adapting to climate change and ensuring energy security is a challenge that any country or business in the world has to face. Although approaches may vary, all oil and gas companies need to be more proactive in responding and adapting to climate change with solutions to: (i) manage climate risks as part of their corporate risk management and (ii) develop a climate change adaptation strategy. The strategies of major IOCs and NOCs in the coming period are directed towards two major strategic trends, namely: energy transition and GHG emission reduction. Most of the Asian NOCs have either implemented low-carbon energy development solutions to gradually replace conventional energy or actively participated in GHG reduction initiatives.

Treatment of heart failure with a preserved ejection fraction
Authors: Ahn Yuran , Youn Jong-Chan
Published: January 2022

Background: Heart failure with preserved ejection fraction (HFpEF) is increasingly prevalent, is associated with high morbidity, and has very few effective treatments.Current Concepts: HFpEF is a heterogeneous syndrome arising from the interplay of cardiac (diastolic, systolic dysfunction, pulmonary hypertension, right ventricular dysfunction, left atrial dysfunction, and chronotropic incompetence) and extracardiac (endothelial dysfunction, skeletal muscle abnormality, pulmonary disease, and renal dysfunction) abnormalities. Although various pharmacological therapies of HFpEF have been introduced and studied, most of them showed a limited clinical benefit. With some advancement in the specific phenotype of HFpEF, diuretics, mineralocorticoid antagonists, sacubitril/valsartan, and lifestyle modifications are recommended as important treatments. Recently, EMPEROR-Preserved trials showed that empagliflozin reduced the combined risk of cardiovascular death or hospitalization for patients with HFpEF, regardless of the presence or absence of diabetes. Several non-pharmacological therapies, including interatrial septal shunt and pacing therapies, have been introduced and are under investigation.Discussion and Conclusion: HFpEF has been recognized as the single greatest unmet need in cardiovascular medicine. Further research is required to understand the concrete pathophysiology for each phenotype of HFpEF. Prevention and management of comorbidities and risk factors for HFpEF are of great importance. Sodiumglucose cotransporter 2 inhibitors may contribute to a change in clinical practice, given the lack of therapeutic options available for patients with HFpEF.
Metric Variation in the Finnic Runosong Tradition: A Rough Computational Analysis of the Multilingual Corpus
Authors: Sarv Mari , Kallio Kati , Janicki Maciej , Mäkelä Eetu
Published: January 2022

This article represents a first step in the corpus-based study of metric variation in Finnic runosong, a poetic tradition shared by several Finnic peoples and documented extensively in the 19th and 20th centuries. Runosong metre has generally been assumed to be a syllabic tetrametric trochee with specific rules about the placement of stressed syllables according to their quantity: long stressed syllables occupy the strong positions in the trochaic schema while short stressed syllables appear in the weak positions. Recent studies by Mari Sarv (2008, 2015, 2019) of Estonian runosong metre have shown, however, that due to linguistic changes, it has gradually lost its quantitative properties and acquired the features of accentual metre. Using computational methods, this study aims to give a preliminary overview of the extent of metric variation on the quantitative-accentual scale across the entire Finnic runosong area. After an approximate syllabification, we apply two separate indirect methods for estimating variation. These appear to generate coherent results: quantitative runosong metre dominates in the north-east and has gradually been replaced by accentual runosong metre towards the south-west. Subsequent studies should verify these results through more precise and detailed investigations.
A Maioria Perseguida: religião, ciência e democracia na audiência pública sobre aborto no STF
Authors: Azevedo Mariana , Efrem Filho Roberto
Published: January 2022

O presente artigo busca contribuir para a compreensão das atuais configurações da religião na controvérsia pública sobre a descriminalização do aborto no Brasil. Para tanto, volta-se à análiseda audiência pública realizada no Supremo Tribunal Federal como parte do processamento da ADPF 442, mas sobretudo às 24 exposições realizadas por representantes de entidades autodenominadas religiosas e pelos demais expositores que citaram a religião para a construção de seus argumentos contrários ou favoráveis à descriminalização do aborto até a 12ª semana de gestação. Tais exposições oportunizam intensas disputas – interiores a uma linguagem de direitos – em torno do conhecimento científico, de diferentes concepções de democracia e da própria religião. Nessas disputas, atores religiosos não raro se identificam como uma maioriaperseguida pelos ‘excessos ideológicos’ característicos de um ‘ativismo judicial’ protagonizado pelos ministros do STF e contrário ao que seria a ‘moral do povo’ brasileiro.

Building Trust and Support for Partnership Agendas through the Requisites of Early Community Involvement
Authors: Ashade Oladimeji , Mutereko Sybert
Published: January 2022

One of the aims of the sustainable development goals (SDGs) is infrastructural development. In pursuance of this goal, partnerships and collaborations remain key responses. Thus, Goal 17, which is the climax of the SDGs, revolves around partnering with private investors to generate the required capital for the attainment of said developmental goals. Using some public-private partnership (PPP) projects as case study, this paper aims to analyse how early involvement or non-involvement influences the project communities to trust the project handlers and give support towards sustainable infrastructural development. The researcher applied qualitative method data gathering techniques and analysis. Findings show that communities that seemed to have been well engaged at the initial stages only experienced ‘therapeutic’ and ‘manipulative’ involvement because firstly there was a flagrant disregard for initial agreed-upon principles and tenets of inclusive governance and secondly the promoters of the collaborations did not do enough to have an all-inclusive advocacy with community groups. The study recommends that the law governing the implementation of PPP in Lagos State be modified to allow community representatives feature prominently on the committee for infrastructural projects right from the initial stage through the entire process.
Comparative assessment of the results of detection of
СagА-positive strains of Helicobacter pylori by molecular-genetic and immunochromatographic methods in different biological
materials

Published: January 2022

A comparative analysis of the detection of CagA-positive strains of H. pylori by immunochromatographic and molecular genetic methods was carried out. We used H. pylori strains isolated from individuals with diseases of the gastrointestinal tract. The immunochromatographic method was implemented using a developed experimental model of an immunochromatographic test system for detecting the H. pylori CagA protein in various biological materials. Determination of the pathogenicity gene cagA of H. pylori was carried out using the «Helikopol SA» test system («Litekh», Russia). The assessment of the comparability of the results of detecting CagA-positive strains of H. pylori was carried out using statistical methods: Monte-Carlo, calculation of the chi-square test (χ2) and Kendall’s τ-b and Somer’s d coefficients. Statistical analysis was performed using the software packages «Microsoft Office Excel», «Statistica 10.0», «WinBUGS 1.4.0.» The study showed the absence of a statistically significant difference and the presence of a direct strong correlation between the results of detecting CagA-positive strains by molecular genetic and immunochromatographic methods, which indicates that these methods provide similar results in identifying highly pathogenic strains of H. pylori.

Among the most significant challenges presented to modern medicine is the problem of cognitive disorders. The relevance of her research is determined by the wide spread of disorders of the higher cortical functions, their significant negative impact on the quality of life of patients, as well as high economic costs on the part of the state and the patient’s relatives aimed at organizing medical, diagnostic and rehabilitation processes. The main cause of cognitive impairment in the elderly is Alzheimer’s disease. Currently, the criteria for the diagnosis of this nosological form have been developed and are widely used in practice. However, it should be noted that their use is most effective if the patient has a detailed clinical picture, at the stage of dementia. In addition, they provide for the study of biomarkers in a number of cases in the cerebrospinal fluid or using positron emission tomography, which presents certain technical difficulties. Especially significant problems arise in the pre-dement stages. This situation dictates the need to search for new promising diagnostic methods that will have high sensitivity and specificity, as well as the possibility of application in the early stages of Alzheimer’s disease, including in outpatient settings. The article provides information about modern methods of computer neuroimaging, discusses the research directions of individual biomarkers, and also shows the prospects for using diagnostic test panels developed on the basis of graphene biosensors, taking into account the latest achievements of nanotechnology and their integration into medical science.
