This paper describes the design and implementation of the MATE workbench, a program which provides support for flexible display and editing of XML annotations, and complex querying of a set of linked files. The workbench was designed to support the annotation of XML coded linguistic corpora, but it could be used to annotate any kind of data, as it is not dependent on any particular annotation s...

La yerba es el ingrediente del mate, la infusión nacional de Argentina. El mate también popular en otros países, especialmente misma región. Por ello, objetivo este trabajo consiste caracterizar mercado y su historia, describir brevemente cómo pandemia ha afectado consumo los precios. Este artículo aporta evidencia a productores para diseñar estrategia marketing. Palabras clave: concentración m...

Under sexual selection, mate preferences can evolve for traits advertising fitness benefits. Observed mating patterns (mate choice) are often assumed to represent preference, even though they result from the interaction between preference, sampling strategy and environmental factors. Correlating fitness with mate choice instead of preference will therefore lead to confounded conclusions about t...

Previous studies on sex-differentiated mate preferences have focused on univariate analyses. However, because mate selection is inherently multidimensional, a multivariate analysis more appropriately measures sex differences in mate preferences. We used the Mahalanobis distance (D) and logistic regression to investigate sex differences in mate preferences with data secured from participants res...

Mate preference for well-adapted individuals may strengthen divergent selection and thereby facilitate adaptive divergence. We performed mate choice experiments in which we manipulated male red crossbill (Loxia curvirostra complex) feeding rates. Using association time as a proxy for preference, we found that females preferred faster foragers, which reinforces natural selection because poorly a...

A measure of Facebook-related mate-retention tactics was developed to investigate the relationship between online behaviors and intimate partner aggression. One hundred and seventy-seven young adults (65 men, 112 women) completed questionnaires that included measures of online and offline mate-retention tactics, Facebook jealousy, Facebook surveillance, and intimate partner violence. A factor a...

Individuals perform mate retention behaviors to minimize the risk of partner infidelity and relationship dissolution. The current study investigates whether consideration of cosmetic surgery can be conceptualized as part of a broader strategy of mate retention for women, but not men. We hypothesized that women's consideration of cosmetic surgery would be positively associated with performance f...

Study of determinants of mate selection by animals has a long history in evolutionary biology and behavioural ecology. However, only during the past decade have investigators begun to conduct experiments exploring the various ways in which observation of the behaviour of others might influence mate selection. Here, we review both field and laboratory studies of behavioural processes that underl...

a r t i c l e i n f o Although much of the research on human mate preference assumes that mate preference and partner choice will be related to some extent, evidence for correlations between mate preference and mate choice is mixed. Inspired by biological market theories of mate choice, which propose that individuals with greater market value will be better placed to translate their preference ...

Abstract Yerba mate is a tree natural from South America, traditionally daily consumed as hot ( chimarrão ) or cold tereré and roasted leaves (mate tea) infusions, being an important source of polyphenols flavonoids in human nutrition. To produce bioactive-rich extracts yerba mate, oven-dried at 35 °C three different commercial products, named M, T, S, were extracted using General Recognized Sa...
