Human resource practices and performance in small Spanish wineries, and their evolution with age and size

This research aims to cover the existing gap in knowledge regarding human resource management practices in winery businesses. Three of the most important practices in this field - recruitment and selection, training and development, and remuneration - and their relationship with performance in small family and non-family wineries as well as the differences in those businesses' behaviours according to their age and size were analysed. The analysis was based on a 2016 database containing 339 Spanish wine sector SMEs, and a multivariate Bayesian regression methodology was applied. The results demonstrate a lower level of human resource management practices in small family businesses and a stronger relationship with performance than in non-family businesses. The results also show that human resource management varies according to the age and size of the company, indicating an inverted U-shaped relationship with size. On the one hand, these results highlight the importance of human resource practices in the environment of a small winery. These practices have not usually been considered as drivers of performance in small family firms. On the other hand, the results can be useful for the managers of such firms, both in the wine industry and in general, as they highlight the human resource practices that could improve the performance of those entities. The paper contributes to filling the existing gap in the literature related to small family businesses. Esta pesquisa visa cobrir a lacuna existente no conhecimento sobre práticas de gestão de recursos humanos em empresas vinícolas. Foram analisadas três das práticas mais importantes neste campo - recrutamento e seleção, treino e desenvolvimento, e remuneração - e sua relação com o desempenho em pequenas adegas, familiares e não familiares, bem como as diferenças no comportamento dessas empresas de acordo com a sua idade e a sua dimensão. A análise foi baseada num banco de dados de 2016 contendo 339 PME do setor vinícola espanhol, tendo sido aplicada a metodologia de regressão bayesiana multivariada. Os resultados demonstram um nível mais baixo de práticas de gestão de recursos humanos em pequenas empresas familiares e uma relação mais forte com o desempenho do que em empresas não familiares. Relatam também que a gestão de recursos humanos varia de acordo com a idade e a dimensão da empresa, encontrando uma relação em U invertido com a dimensão. Por um lado, estes resultados destacam a importância das práticas de recursos humanos no ambiente de uma pequena adega. Estas práticas não têm sido geralmente consideradas como motores de desempenho em pequenas empresas familiares. Por outro lado, os resultados podem ser úteis para os gerentes de tais empresas, tanto na indústria do vinho como na indústria em geral, pois destacam as práticas de recursos humanos que podem melhorar o desempenho dessas entidades. O artigo contribui para preencher a lacuna existente na literatura relativamente às pequenas empresas familiares

The competitive advantage in business, capabilities and strategy. What general performance factors are found in the Spanish wine industry?

The wine sector in Europe has undergone a major change of trend in recent years, especially in Spain. On the one hand, the surface area has been reduced, but the production has been maintained by restructurings and improvements made in exploitation techniques. On the other hand, consumption has diminished causing a significant increase in competition. The Spanish wine sector is formed mainly by small and medium-sized firm, which is representative of the size of existing companies in Europe. This article aims to analyze the relationships between the competitive strategy, resources and capabilities of the firms, analyzing their technological and managerial capabilities, with business performance. 339 companies of the wine sector in Spain have been studied, differentiating between individual firms, cooperatives and mercantile companies. The results reveal that resources and capabilities along with strategies define competitive advantage, but their relationship and importance is different for each type of company

Cold Plus Hot Dark Matter Cosmology in the Light of Solar and Atmospheric Neutrino Oscillations

We explore the implications of possible neutrino oscillations, as indicated by the solar and atmospheric neutrino experiments, for the cold plus hot dark matter scenario of large scale structure formation. We find that there are essentially three distinct schemes that can accommodate the oscillation data and which also allow for dark matter neutrinos. These include (i) three nearly degenerate (in mass) neutrinos, (ii) non-degenerate masses with $\nu_\tau$ in the eV range, and (iii) nearly degenerate $\nu_\mu-\nu_\tau$ pair (in the eV range), with the additional possibility that the electron neutrino is cosmologically significant. The last two schemes invoke a `sterile' neutrino which is light (< or ~ eV). We discuss the implications of these schemes for $\bar{\nu}_\mu - \bar{\nu}_e$ and $\nu_\mu - \nu_\tau$ oscillation, and find that scheme (ii) in particular, predicts them to be in the observable range. As far as structure formation is concerned, we compare the one neutrino flavor case with a variety of other possibilities, including two and three degenerate neutrino flavors. We show, both analytically and numerically, the effects of these neutrino mass scenarios on the amplitude of cosmological density fluctuations. With a Hubble constant of 50 km s$^{-1}$ Mpc$^{-1}$, a spectral index of unity, and $\Omega_{baryon} = 0.05$, the two and three flavor scenarios fit the observational data marginally better than the single flavor scheme. However, taking account of the uncertainties in these parameters, we show that it is premature to pick a clear winner.Comment: 1 LaTEX file plus 1 uuencoded Z-compressed tar file with 3 postscript figure

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Synthetic trehalose di- and mono-esters of alpha-, methoxy- and keto-mycolic acids

Synthetic mycolic acids matching the overall structure of the major mycolic acids of Mycobacterium tuberculosis are coupled to trehalose to generate the corresponding synthetic trehalose monomycolate (TMM) and trehalose dimycolate (TDM; cord factor), either with two identical or two different mycolic acids
