Organizational performance under macroeconomic pressure: an empirical analysis
Publication . Godinho Antunes, Marina; Ribeiro Mucharreira, Pedro; Texeira Fernandes Justino, Maria do Rosário; Texeira Quirós, Joaquín
Previous studies have emphasized that many parents from marginalized communities experience a sense of disconnection from formal education, particularly in relation to school mathematics, which often appears abstract and unrelated to everyday experiences. This research investigates the influence of key macroeconomic variables on organizational performance, with a specific focus on small and medium-sized enterprises (SMEs), which are particularly susceptible to economic fluctuations. The study assessed the effects of four macroeconomic indicators—interest rate, inflation rate, Gross Domestic Product (GDP) growth, and investment—on the financial performance of 4,428 Portuguese SMEs over an eleven-year period. Firm performance was measured using the Return on Equity (ROE) financial indicator. A multiple linear regression model was applied to examine the relationship between ROE and the selected macroeconomic variables. The results indicated that the inflation rate and investment were statistically significant predictors of ROE. Specifically, a one-unit increase in the inflation rate was associated with an average rise of 22.303 in ROE, whereas a one-unit increase in investment corresponded to a decrease of 6.816. This reflects a positive relationship between inflation and ROE, and a negative one between investment and ROE. Interest rate and GDP growth, although included in the initial model, were ultimately excluded due to their lack of statistical significance.
Exploring the link between quality and the bottom line: a literature review
Publication . Texeira Fernandes Justino, Maria do Rosário; Rivera-Fernández, Gala; Godinho Antunes, Marina; Ribeiro Mucharreira, Pedro; Texeira Quirós, Joaquín
Enhancing product and service quality serves as a strategic lever for businesses to strengthen or sustain their competitive position. While extensive research exists on quality management systems, the empirical evidence regarding ISO9000 certification's influence on organizational performance remains inconclusive, with studies presenting divergent findings. This paper systematically examines existing literature to investigate the complex interrelationships among quality management implementation, ISO9000 certification, associated quality costs, operational outcomes, and their collective impact on firm performance. Through this comprehensive review, we aim to provide clarity on these critical connections within the quality management domain.
Advanced double-flush riveting for multistage forming tools
Publication . Silva, Carlos M. A.; Pragana, João P. M.; Sampaio, Rui F. V.; Bragança, Ivo M. F.; Martins, Paulo A. F.; Bragança, Ivo
This paper presents a novel double-flush riveting process for creating lap joints in sheet metal parts. The process involves punching, forging, and shaving to produce countersunk holes with precise geometry, followed by compression of cylindrical rivets into the holes of two overlapped sheet parts to create form-closed mechanical interlocks. Experimental and numerical analyses examine the influence of the primary process parameters on interlock quality and required forming and destructive forces. The investigation is a step forward in joining technology by offering a simple alternative to welding, bonding, and mechanical joining, with seamless integration into multistage forming tools.
Is Portugal Gaming with the Performance Feedback of the Late Payments Directive? Evidence from the Portuguese Municipalities
Publication . Gomes dos Santos, P.; Albuquerque, F.
This paper aims to assess the possible use of gaming by the Portuguese government by allowing Portuguese municipalities not to consider all the short-term liabilities on the European Late Payments Directive (LPD) performance measurement. The analysis is based on data from 308 Portuguese municipalities from 2014 to 2019, using panel data regression. A breakdown by those local governments that comply, or do not, with the LPD threshold, as well as by size classes is also performed to provide a more in-depth analysis of findings. The findings indicate that the total debt of Portuguese municipalities is significantly explained by commercial liabilities that are not considered in the LPD performance measurement. They also show that the payment period has reduced on average, but is still not aligned with the LPD 30-day objective. Moreover, the larger local governments are the ones with the lower payment period on average, mostly complying with the LPD threshold. Despite being limited to municipalities and a single country, its findings may highlight the need for defining common performance measures for the European Union (EU), since Portugal is a member state. This can be relevant for policy-makers but also for a broader audience that includes local citizens and regulatory bodies within the EU.
Modos de fazer-ver a obra coreográfica: a construção da Identidade coreográfica a partir de Victor Hugo Pontes
Publication . Xavier, Madalena; Xavier, Madalena; Fernandes, João; Fernandes, João; Dança com Diálogos - Associação Cultural (Lisboa)
Modos de Fazer-Ver a Obra Coreográfica — A Construção da Identidade Coreográfica a partir de Victor Hugo Pontes é um estudo dedicado à obra e ao percurso do coreógrafo português Victor Hugo Pontes, explorando os processos de criação, as práticas colaborativas e os recursos expressivos que definem a sua identidade coreográfica.
Este livro resulta da investigação realizada no âmbito do projeto "Modos de fazer ver a obra coreográfica – o percurso de Victor Hugo Pontes", financiado pelo Concurso de Investigação, Desenvolvimento, Inovação e Criação Artística (IDI&CA)dinamizado pelo Instituto Politécnico de Lisboa, 2023.
A investigação foi conduzida por João Fernandes e Madalena Xavier, ambos Professores Coordenadores da Escola Superior de Dança do Instituto Politécnico de Lisboa e membros integrados do INET-md (Instituto de Etnomusicologia — Centro de Estudos em Música e Dança).
A obra propõe uma reflexão aprofundada sobre os modos de materializar, analisar e compreender a obra coreográfica contemporânea em Portugal.
