Haas-Molnar Continued Fractions and Metric Diophantine Approximation.
No full textHaas–Molnar maps are a family of maps of the unit interval introduced by A. Haas and D. Molnar. They include the regular continued fraction map and A. Renyi’s backward continued fraction map as important special cases. As shown by Haas and Molnar, it is possible to extend the theory of metric diophantine approximation, already well developed for the Gauss continued fraction map, to the class of Haas–Molnar maps. In particular, for a real number x, if (p n /q n )n≥1 denotes its sequence of regular continued fraction convergents, set θ n (x) = q 2n|x − p n /q n |, n = 1, 2.... The metric behaviour of the Cesàro averages of the sequence (θ n (x))n≥1 has been studied by a number of authors. Haas and Molnar have extended this study to the analogues of the sequence (θ n (x))n≥1 for the Haas–Molnar family of continued fraction expansions. In this paper we extend the study of n≥1 for certain sequences (k n )n≥1, initiated by the second named author, to Haas–Molnar maps
INCOME OF HOUSEHOLDS WITH CHILDREN AND CHILD POVERTY
No full textPreventing and alleviating child poverty constitute main concerns for the strategies and policies in the field of social protection and social inclusion in the European Union, and significantly reduce child poverty, as one of the core objectives of these strategies. Setting up policies of child poverty alleviation implies knowing the dimensions and characteristics of this phenomenon, the reasons behind it and conditions that favour it, firstly of those determining the low level of incomes at the disposal of many families with children. The paper comprises an analysis of the level, structure and dynamics of incomes in households with children and of the main parameters of child poverty in Romania. Comparisons with Member States of the European Union are provided also.poverty, child poverty, poverty rate, disposable income

Equity in unequal deductions : implications of income tax rules in Ghana and Nigeria
No full textIn many African countries, the amount of personal deduction for income tax purposes increases with the taxpayer's income. At first glance, this appears to give larger tax breaks to the rich than to the poor. On closer examination, this notion turns out to be false. As this paper shows, each tax system with"income dependent tax deductions"(IDTDs) is fully equivalent to a particular conventional progressive tax system with standard deductions. One implication for comparative tax research is that the tax schedule of a country that uses IDTDs should not be compared directly with a conventional tax schedule in another country. Existing cross-country work on tax deductions and marginal tax rates generally fails to recognize that IDTDs invalidate a straightforward comparison. To make the two systems comparable, a transformation like the one suggested in this paper is needed.Public Sector Economics&Finance,Environmental Economics&Policies,Tax Policy and Administration,Taxation&Subsidies,Governance Indicators

Traduzindo as metamorfoses de narradora-mãe-tradutora: Marcela Lanius e a "Máquina de Leite", de Szilvia Molnar
No full textThe Nursery is a novel written in English by Szilvia Molnar and translated into Brazilian Portuguese by Marcela Lanius. The text, narrated in the first person by a nameless protagonist, is a careful writing project between the author and her translator character, the latter on the verge of becoming a mother through language. Marked by the often grotesque tone of the bodily metamorphosis of the postpartum period, the novel requires the translator to articulate herself and the target language in order to make the translation project resonate with the brutal and affective experiences of motherhood. In this interview, Marcela Lanius discusses her translation project, which sought to understand, translate, and recreate the strangeness of the source text.Máquina de Leite é um romance escrito, em inglês, por Szilvia Molnar, e traduzido ao português brasileiro por Marcela Lanius. O texto, narrado em primeira pessoa por uma protagonista sem nome, é um cuidadoso projeto de escrita entre a autora e sua personagem tradutora, esta última em vias de se tornar mãe pela linguagem. Marcado pelo tom muitas vezes grotesco da metamorfose corporal do pós-parto, o romance exige de quem traduz a articulação de si, e da língua de chegada, a fim de fazer o projeto de tradução ecoar em experiências brutais e afetivas da maternidade. Nesta entrevista, Marcela Lanius conta sobre o seu projeto de tradução que procurou entender, traduzir e recriar as estranhezas do texto de partida
Women and forestry : operational issues
No full textWomen are major actors in forestry throughout the developing world. Women and children are the primary collectors of fuel and fodder for home consumption and for sale to urban markets. This alone gives women a major role in the management and conservation of renewable forest resources. When convinced of the utility and practicality of a forest improvement or management scheme, women can be a powerful lobby to persuade their entire houshold or community to invest the resources necessary to make the scheme work. Involving women in forestry projects often makes the difference between achieving or not achieving project objectives, particularly for the long-term sustainability of interventions.Environmental Economics&Policies,Forests and Forestry,Forestry,Agricultural Knowledge&Information Systems,Health Monitoring&Evaluation
PEOPLE LEFT BEHIND: TRANSITIONS OF THE RURAL POOR
No full textCompared to their urban counterparts, the rural poor are more likely to be employed, more apt to be members of married-couple families, less likely to be children, less likely to be minority, and more likely to have assets but a negative income. This paper examines poverty rates and factors that affect mobility in and out of poverty among major categories of the rural poor. Particular attention is paid to farm workers and the rural farm population in the South. It endeavors to identify both structural conditions that perpetuate rural poverty and government interventions that ameliorate human suffering and break the cycle of poverty reproduction.Community/Rural/Urban Development,
Enhancing Water Resilience in Haiti: Understanding Extreme Events and Urbanization Effects.
No full textWater supply, management, and associated risks are constant concerns for the Haitian population. The country faces severe issues such as waterborne diseases, cyclones, floods, landslides, and droughts every year. These challenges are exacerbated by climate change, increasing the frequency and intensity of extreme weather events. In response, the Université d'État d'Haïti à Limonade (UEH-CHCL) and Auburn University have partnered to establish a water resilience unit in northeastern Haiti, aiming to improve water resource management, support climate change adaptation, and foster research and innovation. Addressing these issues in Haiti requires using novel data sources, as the ground-based monitoring networks that form the basis of water resources management in the United States and other developed countries are not available.
This study explores the use of novel data sources to evaluate flood and drought scenarios in the Grande Rivière du Nord watershed, a critical region for agriculture and water supply, supporting thousands of people and essential for food security. We investigated hydrological trends and patterns to understand the impacts of climate change and urbanization on water resources. We analyzed two key hydrological variables: maximum annual precipitation and maximum instantaneous discharge. For precipitation data, we used the Global Precipitation Measurement Integrated Multi-Satellite Retrievals (GPM-IMERG) from Earthdata and for discharge, we used the GeoGLOWS Global Streamflow and Flood Forecasting System. Due to current travel restrictions in Haiti, which significantly impacted our ability to collect field data, we utilized gridded data products with suitable spatial and temporal resolution as a surrogate. An annual maxima series spanning approximately 25 years (2000–2025) was constructed for each variable. We fitted Gumbel and Lognormal distributions to the data using L-moment methods. We applied goodness-of-fit tests to identify the best fitting distribution, including root mean square error (RMSE), mean absolute error (MAE), and probability plot correlation coefficient (PPCC). Furthermore, we calculated exceedance probabilities, enabling the determination of return periods of 2, 10, 20, 50, and 100 years.
Furthermore, hydrological modeling scenarios were developed using HEC-HMS to assess the impact of urbanization on streamflow patterns and flood risks. A baseline scenario with no impervious surface was compared to two post-urbanization scenarios: one based on impervious surface estimates from 2023 Environmental Systems Research Institute (ESRI) land cover data, and another representing a 20% increase in imperviousness. The model was calibrated using GeoGLOWS streamflow data corrected with the Simbi hydrological database. This research contributes to enhancing water resilience in Haiti and supports informed decision-making for improved water resource management and flood risk mitigation
