Impacto del incumplimiento de las entregas de productos en el retorno de la inversión

The purpose of this article is focused on analyzing the impact of non-compliance with product deliveries on the return on investment for the company Avántika Colombia S.A.S, located in the city of Barranquilla, by means of the financial indicator known as the Cash Cycle; taking into account the main actors in this supply chain, such as suppliers and customers, as well as the management of the company's financial resources. An investigative structure is proposed based on the following fronts: 1. Data collection (Database of the Dinamic Modular System, company DMS); 2. Data analysis; 3. Calculation of the Cash Cycle. Through the analysis of the results, we seek to be aware of how the level of service negatively impacts the organization from a financial point of view, that is, how it impacts the fact of delivering the merchandise late, measuring the capacity it has the supply chain to turn the investment back into money. In this sense, we can say that a positive cash cycle allows the company to leverage efficiently, that it operates through its own resources and does not increase its indebtedness with third parties, which is given through the timely and correct taking of decisions, achieving higher level of stability and competitiveness compared to other companies in the same sector. This indicator provides us with a managerial vision of how the logistics process is being carried out and thus, seek improvement strategies for it.El objeto del presente artículo se centra en analizar el impacto del incumplimiento de las entregas de productos en el retorno de la inversión para la empresa Avántika Colombia S.A.S, ubicada en la ciudad de Barranquilla, por medio del indicador financiero conocido como Ciclo de Efectivo; teniendo en cuenta los principales actores de esta cadena de abastecimiento, como los proveedores y los clientes, así como también, el manejo de los recursos financieros de la empresa. Se plantea una estructura investigativa a partir de los siguientes frentes: 1. Recopilación de datos (Base de datos del sistema Dinamic Modular System, DMS de la compañía); 2. Análisis de datos; 3. Cálculo del Ciclo de Efectivo. Mediante el análisis de los resultados, se busca estar al tanto de cómo impacta negativamente a la organización el nivel de servicio desde un punto de vista financiero, es decir, cómo impacta el hecho de entregar la mercancía de manera tardía, midiendo la capacidad que tiene la cadena de suministro de convertir lo invertido nuevamente en dinero. En este sentido, podemos decir que un ciclo de efectivo positivo, permite a la empresa apalancarse de manera eficiente, que esta opere por medio de recursos propios y no incremente su endeudamiento con terceros, lo cual, se da mediante la oportuna y correcta toma de decisiones, logrando mayor nivel de estabilidad y competitividad en comparación con las demás empresas del mismo sector. Este indicador, nos brinda una visión gerencial de cómo se está llevando a cabo el proceso logístico y así, buscar estrategias de mejora para el mismo

Sometidos a esclavitud: los africanos y sus descendientes en el Caribe Hispano

Con autorización de la editorial para este libro. La edición estuvo a cargo de Consuelo Naranjo Orovio.Sometidos a esclavitud: los africanos y sus descendientes en el Caribe hispano contribuye al estudio de la historia Atlántica en la que la esclavización de millones de africanos fue uno de principales factores que generaron e impulsaron el desarrollo del mundo moderno. La formación de redes comerciales, compañías mercantiles y negocios particulares contribuyeron a conectar mundos y a hacerlos interdependientes. Junto a las mercancías, individuos y productos, viajaron ideas y tradiciones que fueron tejiendo la historia atlántica. En ella, la esclavización, los esclavizados y los afrodescendientes fueron y son partes destacadas, como muestra su legado presente de las culturas americanas. Estos estudios de la obra se suman a investigaciones que, desde distintos países, proyectos, grupos de investigación y enfoques, se están realizando sobre un tema tan rico, diverso y complejo como es la esclavitud atlántica. El espacio temporal que recorren los capítulos se prolonga en el tiempo como lo hizo la trata y el sistema esclavista. Lo mismo ocurre con los territorios afectados por este fenómeno. Su cartografía es una larga sombra que se expande por el mundo atlántico desde el siglo XVI hasta las últimas décadas del siglo XIX. Distintos actores y puntos de África, Europa y América emergen como protagonistas del sometimiento, el comercio y la esclavización de más de doce millones y medio de africanos.Este libro se inserta en el proyecto europeo Connected Worlds: The Caribbean, Origin of Modern World.

Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study

Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.
