connecting degree programs from individuals’ choices

Candia, C., Encarnação, S., & Pinheiro, F. L. (2019). The higher education space: connecting degree programs from individuals’ choices. EPJ Data Science, 8(1), [39]. https://doi.org/10.1140/epjds/s13688-019-0218-4Data on the applicants’ revealed preferences when entering higher education is used as a proxy to build the Higher Education Space (HES) of Portugal (2008–2015) and Chile (2006–2017). The HES is a network that connects pairs of degree programs according to their co-occurrence in the applicants’ preferences. We show that both HES network structures reveal the existence of positive assortment in features such as gender balance, application scores, unemployment levels, academic demand/supply ratio, geographical mobility, and first-year drop-out rates. For instance, if a degree program exhibits a high prevalence of female candidates, its nearest degree programs in the HES will also tend to exhibit a higher prevalence when compared to the prevalence in the entire system. These patterns extend up to two or three links of separation, vanishing, or inverting for increasing distances. Moreover, we show that for demand/supply ratio and application scores a similar pattern occurs for time variations. Finally, we provide evidence that information embedded in the HES is not accessible by merely considering the features of degree programs independently. These findings contribute to a better understanding of the higher education systems at revealing and leveraging its non-trivial underlying organizing principles. To the best of our knowledge, this is the first network science approach for improving decision-making and governance in higher education systems.publishersversionpublishe

The Origin of Citizen Genet’s Projected Attack on Spanish Louisiana: A Case Study in Girondin Politics

In 1792 the Girondin ministry decided to send Edmond Genet to the United States with plans to recruit western frontiersmen and invade Spanish Louisiana. The episode is well known in American history, but the literature on its French origin is sparse and overemphasizes the contribution of revolutionary leader Jacques- Pierre Brissot. This essay contextualizes the French decision within the debate between Brissot, Minister of Foreign Affairs Pierre Lebrun, and General Charles-François Dumouriez over whether France should send troops against Spanish colonies in South America. The essay argues that Lebrun promoted the western scheme in order to attack Spanish interests without straining French resources. Rather than merely embodying a spirit of universal freedom, Lebrun’s plan was grounded in the geopolitical advantages the mission might afford France in its European wars

Scaling behavior of public procurement activity

The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.Public procurement refers to the purchase by public sector entities—such as government departments or local authorities—of Services, Goods, or Works. It accounts for a significant share of OECD countries’ expenditures. However, while governments are expected to execute them as efficiently as possible, there is a lack of methodologies for an adequate comparison of procurement activity between institutions at different scales, which represents a challenge for policymakers and academics. Here, we propose using methods borrowed from urban scaling laws literature to study public procurement activity among 278 Portuguese municipalities between 2011 and 2018. We find that public procurement expenditure scales sublinearly with population size, indicating an economy of scale for public spending as cities increase their population size. Moreover, when looking at the municipal Scale-Adjusted Indicators (the deviations from the scaling law) by contract categories—Works, Goods, and Services—we are able to identify a richer local characterisation of municipalities based on the similarity of procurement activity. These results make up a framework for quantitatively studying local public expenditure by enabling policymakers a more appropriate foundation for comparative analysis.publishersversionotherpublishe

PREMIVM – improving grape quality with multiparametric field analysis of grapes and leaves in vineyards

European wine industry is a strategic economic sector that is nowadays facing a growing competition in the international market at the same time it as to deal with predictable lower support from the CAP. Taking into consideration that the use of ICT can support the development of new tools and devices that can reduce costs and increase final product quality/quantity an international consortium that comprises 3 technical companies and 3 winegrowers together with 3 research groups setup the EU Project PREMIVM. In this work will present the PREMIVM decision support system that was developed including the field device for data collection - WINEPEN, the web information management system for data storage, processing and information visualization, and the smartphone interface for information deliveryinfo:eu-repo/semantics/publishedVersio

Espondilolise e espondilolistese ístmica de grau I no adolescente: Análise retrospectiva de 30 casos

Objectivo: a espondilolise e a espondilolistese ístmica grau I são causas de lombalgia nos adolescentes e associam-se a fractura de fadiga da pars interarticularis por movimentos repetidos de hiperextensão. Na literatura não existe consenso quanto aos benefícios do tratamento cirúrgico nestes doentes, muitas vezes atletas, e a controvérsia prolonga-se sobre qual a melhor técnica cirúrgica. Os autores descrevem a técnica cirúrgica que sistematicamente utilizam e analisam os resultados obtidos.Material e métodos: retrospectivamente, entre 2004 e 2013, foram avaliados 30 adolescentes, 12 com lise ístmica e 18 com espondilolistese ístmica grau I, operados pelo mesmo cirurgião. A reconstituição ístmica foi feita com autoenxerto de ilíaco e fixação pedicular posterior temporária. Avalia-se a taxa de consolidação, complicações, dor (VAS), função (ODI) e o grau de satisfaçãoResultados: a idade média foi 16.3 anos (13-18) e o seguimento 23.5 meses (14-48). Ocorreu consolidação em 100% dos casos. O VAS médio reduziu de 7.48 para 0.38 (p<0.0001) e, funcionalmente, o ODI médio melhorou de 38.55% para 1.59% (p<0.0001), de disfunção moderada para mínima. A todos os doentes foi retirado o material após 1 ano de reconstituição ístmica. No total, 63.3% dos doentes eram desportistas e todos retomaram o nível prévio. Não se verificou progressão da listese nem complicações significativas. Os doentes encontram-se satisfeitos e repetiriam o tratamento.Conclusão: as técnicas de artrodese obtêm bons resultados clínicos mas implicam perda de mobilidade segmentar e doença do nível adjacente. Comparativamente com técnicas dinâmicas, a técnica preconizada pelos autores permite não só a reconstituição ístmica eficaz como revela resultados superiores a médio prazo, o que supera a necessidade de segunda intervenção para extração do material. A reconstituição ístmica com autoenxerto e fixação pedicular posterior temporária na espondilolise ou espondilolistese ístmica grau I obteve excelentes resultados clínicos e elevada taxa de consolidação. Esta técnica é defendida pelos autores mesmo em atletas de alta competição

Métodos de desmama para aumento da eficiência reprodutiva de bovinos de corte.

O longo período de anestro pós-parto, observado em vacas, em sistema de criação extensiva, e um dos principais fatores responsáveis pelo baixo desempenho reprodutivo do rebanho de bovinos de corte. Tem sido demonstrado que a deficiência nutricional e a intensidade da amamentação retardam significativamente a manifestação do primeiro cio pós-parto. Portanto, o objetivo deste trabalho foi o de discutir o efeito de diferentes praticas de desmama no desempenho reprodutivo de vacas de corte e no desenvolvimento de seus bezerros.bitstream/item/104728/1/Metodos-de-desmama-para-aumento.pdf1.reimpr
