O objetivo do estudo foi avaliar a diversidade genética e fornecer informações sobre os principais ancestrais e fundadores de um novo criador de cavalos da raça Puro-sangue Lusitano (PSL), que selecionou os animais para a disciplina equestre de saltos de obstáculos. Foram avaliadas 16 éguas da população Lusitano Sport Horses (pLSH) com nascimentos de 2016 a 2021 e compilados os pedigrees utilizados nas análises...
Due to non-stationary, high volatility, and complex nonlinear patterns of stock market fluctuation, it is demanding to predict the stock price accurately. Nowadays, hybrid and ensemble models based on machine learning and economics replicate several patterns learned from the time series. This paper analyses the SARIMAX models in a classical approach and using AutoML algorithms from the Darts library. Second, a ...
A poupança é um comportamento positivo (OECD, 2016), que se traduz em bem-estar financeiro para os indivíduos e as famílias. A poupança de longo prazo oferece a possibilidade de um padrão de consumo doseado ao longo do tempo e a poupança regular e de curto prazo (i.e., de emergência) oferece uma almofada protetora do poder de compra face a um choque no rendimento (Mahdzan e Tabiani, 2013).
This paper presents a systematic review of the literature on financial literacy and savings. A total of 183 articles published between 2005 and 2019 were analyzed. The review relied on hybrid methods, namely, descriptive, semantic network and narrative analyses. The lexical analysis of the articles’ abstracts identified 11 themes: financial literacy, financial literacy measurement, correlates, savings, savings ...
This study's main objective was to identify which of gamblers' demographic, geographic and socioeconomic characteristics correlate with more frequent lottery playing and stock market trading. The data were collected from two unrelated cross-sectional samples of equity investors and lottery players from a European country. Based on a multiple correspondence analysis of both samples, higher levels of spending on ...
Millimeter waves and massive MIMO are a promising combination to achieve the multi-Gb/s required by future 5G wireless systems. However, fully digital architectures are not feasible due to hardware limitations, which means that there is a need to design signal processing techniques for hybrid analog-digital architectures. In this manuscript, we propose a hybrid iterative block multiuser equalizer for subconnect...
This paper proposes a novel demand response model using a fuzzy subtractive cluster approach. The model development provides support to domestic consumer decisions on controllable loads management, considering consumers’ consumption needs and the appropriate load shape or rescheduling in order to achieve possible economic benefits. The model based on fuzzy subtractive clustering method considers clusters of dom...
The sticky-information model appeared in order to offer a more empirically consistent view on the effects of monetary policy than the one provided by the benchmark sticky prices setup. Such inattentiveness framework was built on the assumption that current decisions are mainly based on past expectations about the current state of the economy. In this note, we propose an explanation for information stickiness th...
The New Keynesian model has recently been subject to two serious criticisms: the model cannot produce plausible inflation and output dynamics following a monetary shock, and the stability of its dynamics suffers from indeterminacy. The procedures that have been proposed to eliminate these two shortcomings fall into two categories: the introduction of some sort of backward price indexation into the standard mode...
