Competitiveness on a small and large scale is necessary for growth. A definitive link between the level of competitiveness and growth has been difficult to prove. One of the primary objectives of economic planning is to promote price and exchange rate stability. Entrepreneurialism and productivity also increase the country's export competitiveness. The aim of this study is to test for the convergence in competitiveness and convergence club existence in selected economies. No previous research had tested for convergence in competitiveness using a nonlinear timevarying factor model. This paper provides an overview on convergence in competitiveness and convergence clubs' existence for 42 countries using quarterly data from 1994q1 to 2020q4 testing on competitiveness. Convergence log (t) test results show differences in competitiveness between classified convergence clubs. Russia, Brazil, and Turkey are the clubs (groups of countries) that show a transitional path (convergence in competitiveness) that differs entirely from the rest of the sample. Countries with more natural resources and exogenous monetary policies follow a unique development path to competitiveness. We find no evidence of divergence in countries within the clubs. However, we find a club (group of countries) following a clear divergence path from the other countries (Russia, Brazil, and Turkey). Our findings could potentially explain the increase in divergence in competitiveness across countries after the financial crisis of 2008. [ABSTRACT FROM AUTHOR]

The aim in this study is to analyze the current stage of conceptual convergence between Brazilian accounting standards applied to the public sector (NBCTSP) and the International Public Sector Accounting Standard (IPSAS). The complexity and range of transactions between public or private sector entities, as a result of market internationalization, demand continuous and dynamic assessment of the events that promote quantitative or qualitative equity changes. For this evaluation process, observing accounting principles and standards is important to guarantee, among other information characteristics, understandability and comparability, thus reducing costs for investors and users in general, in view of the barriers raised by diverse languages, cultures, tax and economic policies. For convergence analysis, the standards' contents were subject to a comparative study, based on a descriptive analysis, with a view to verifying the existing adherence between Brazilian and international standards applied to the public sector. The results found highlight that different aspects still have to be discussed with a view to an actual convergence with the international standards; the current convergence is partial. The high-quality conceptual exposure of the NBCPSPs is observed though, while the contents of the IPSAS are more focused on operating procedures. [ABSTRACT FROM AUTHOR]

Morphometric analyses of vegetative and floral characters were conducted in 21 populations of five Pleurothallis (Orchidaceae) species occurring in Brazilian ‘campo rupestre’ vegetation. A phylogenetic analysis of this species group was also carried out using nuclear ribosomal DNA internal transcribed spacers (ITS1 and ITS2). Results of the ordination and cluster analyses agree with species’ delimitation revealed by taxonomic and allozyme studies. The groups formed in ordination analysis correspond to the pollinator groups determined in a previous pollination study. Relationships among the species in the cluster analysis using only vegetative characters are similar to those found in a previous allozyme study, but those indicated by cluster analysis using only floral characters differ. These results support the hypothesis that floral similarities are due to convergence driven by similar pollination mechanisms, and therefore floral traits may not be good indicators of phylogenetic relationships in this group. The results of the phylogenetic analysis support this conclusion to some extent. There is no correlation between genetic (allozyme) and morphological variability in the populations nor in the way this variability is distributed among conspecific populations. We describe a new subspecies of Pleurothallis ochreata based on differences in vegetative and chemical characters as well as geographic distribution. Absence of differentiation in floral characters, attraction of the same pollinator species, interfertility and genetic similarity support the argument for subspecific rather than specific status.
