Real and complex integral closure, Lipschitz equisingularity and applications on square matrices

Recently the authors investigated the Lipschitz triviality of simple germs of matrices. In this work, we improve some previous results and we present an extension of an integral closure result for the real setting. These tools are applied to investigate classes of square matrices singularities classified by Bruce and Tari

Can the distributional impacts of macroeconomic shocks be predicted? A comparison of the performance of macro-micro models with historical data for Brazil

What was the impact of Brazil's 1998-99 currency crisis-which resulted in a change of exchange rate regime and a large real devaluation-on the occupational structure of the labor force and the distribution of incomes? Would it have been possible to predict such effects ahead of the crisis? The authors present an integrated macro-micro model of the Brazilian economy in 1998. The model consists of an applied general equilibrium macroeconometric component, connected through a set of linkage aggregate variables to a microeconomic model of household incomes. The authors use this framework to predict the employment and distributional consequences of the 1999 Brazilian currency crisis, based on 1998 household survey data. They then test the predictive performance of the model by comparing its simulated results with the actual household survey data observed in 1999. In addition to the fully integrated macro-micro model, the authors also test the performances of the microeconometric model on its own, and of a"representative household groups"approach. They find that the integrated macro-micro econometric model, while still inaccurate on many dimensions, can actually predict the broad pattern of the incidence of changes in household incomes across the distribution reasonably well, and much better than the alternative approaches. The authors conclude that further experimentation with these tools might be of considerable potential usefulness to policymakers.Labor Policies,Payment Systems&Infrastructure,Economic Theory&Research,Banks&Banking Reform,Environmental Economics&Policies,Economic Theory&Research,Environmental Economics&Policies,Macroeconomic Management,Inequality,Economic Stabilization

Determination of metabolite profiles in tropical wines by 1H NMR spectroscopy and chemometrics.

The aim of this work was to determine metabolite profiles of tropical wines produced in northeast Brazil, by using 1H NMR spectroscopy in comoination with chemometric methods to analyze and discrirninate wine samples from 2007 vintages produced by different wineries

The critical success factors of GDPR implementation - a systematic literature review

Purpose: The digital paradigm people live in today, which drastically increased the consumption of data, is a threat to their privacy. To create a high level of privacy protection for its citizens, the European Union proposed the General Data Protection Regulation (GDPR), which introduces obligations for organizations regarding the storing, processing, collecting and disclosing of data. This paper aims to identify the critical success factors of GDPR implementation. Design/methodology/approach: A systematic literature review was conducted by following a strict review protocol, where 32 documents were found relevant to perform the review and to answer to the proposed research questions. Findings: The critical success factors of GDPR implementation were identified, including barriers and enablers. Furthermore, benefits of complying with GDPR were identified. Research limitations/implications: As GDPR is a relatively recent subject, there are still few scientific papers about it. Therefore, the authors were unable to neither identify nor present a robust conclusion regarding specific topics, such as practical outcomes. Originality/value: On the basis of the literature, the identified critical success factors may be useful for organizations as these can be better prepared to achieve compliance by prioritizing the enablers and avoiding the barriers.info:eu-repo/semantics/acceptedVersio
