In this study, a logistic regression model is applied to credit scoring data from given Portuguese financial institution evaluate the default risk of consumer loans. It was found that increases with loan spread, term and age customer, but decreases if customer owns more cards. Clients receiving salary in same banking have less chances than clients their another institution. We also lowest income tax echelon propensity default. The predicted correctly 89.79% cases.

Throughout Coronavirus any future lockdowns, crucial that needs students be ultimately regularly met they are supported effectively. We intend to address skill shortages mismatches,...

This work presents two mixed-integer programming models that intend to minimize the costs of picking and storage operation through better planning organization places occupied by products in warehouse. A large customer stores frozen goods a Portuguese cold chain logistics company was selected for analysis allocation warehouse corresponding outbound movements. Data with 8525 movements occurred during 2021 were collected 228 different product references. For this case study, had place initial...

ABSTRACT The main objective of this study is to empirically test capital structure decisions in Portuguese family-owned businesses under trade-off theory (TOT) and pecking order (POT) attend the relationships between family/business interaction agency conflicts. Family-owned are essential for development economies, but financing logic they adopt not yet adequately clarified by scientific research, especially as more exposed constraints markets imperfections. specific pattern business...

A new approach to study the compatibilization effect of organophilic clays in PA6/PP polymer blends through experimental results tests is presented. This focuses on description interphase by addition organoclays into blend melt compounding using a Twin Screw Extruder. The variations, uncompatibilized and compatibilized blend, are studied parametric non-parametric analysis variance. For all results, significant differences between were identified.

This paper presents an empirical study of the capital structure Portuguese companies where main objective is to find key explanatory factors for indebtedness decisions. The relations between and its determinants are tested in light Trade-Off Theory Pecking-Order Theory. motivation this work was contribute scientific research on influential deepen knowledge market. quantitative methodology used, through econometric model panel data using accounting information 55 2014 2016. Statistical tests...

Global Entrepreneurship Monitor is a large scale database for internationally comparative entrepreneurship that includes information about many aspects of activities, perceptions, conditions, national and regional policy, among others, number countries. This project has two main sources primary data: the Adult Population Survey National Expert Survey. In this work 2011 2012 datasets are studied. Our goal to analyze effects different type expert specialization on perceptions Entrepreneurial...

The 2019 pandemic had a direct impact on all educational stakeholders. While many teachers and trainers regarded the changes with some scepticism, others embraced opportunity to integrate technology into their teaching-and-learning methods resources. As translation trainers, it is essential follow understand market. Translators require vast competencies, amongst which flexibility adapt. In training, project-based learning (PBL) has been established as an method, proven foster development of...

Abstract This paper addresses a case study regarding inventory models for acquiring liquefied petroleum gas (LPG) cylinders. is an industrial challenge that was proposed at European Study Group with Industry, by Portuguese energy company, which the LPG cylinder main asset of its business. Due to importance this asset, acquisition plan must be defined in order determine amount cylinders acquire, and when acquire them, optimize investment. As are returned refilled, reverse logistic flows these...

The Minimization of Open Stacks Problem (MOSP) is a Pattern Sequencing that often arises in industry. Besides the MOSP, there are also other related Problems similar relevance. In this paper, we show each feasible solution to MOSP results from an ordering vertices graph defines instance solve, and can be seen as edge completion problem renders interval graph. We review concepts theory, particular graphs, comparability graphs chordal provide insight structural properties admissible solutions...
