Approche communicationnelle et organisationnelle des enjeux du Community Management

2014

This paper describes a research program within Information and Communication Sciences (ISC). This program is based on the understanding of online socialization processes. Particularely, it is focused on rationalization issues for communities forms and rules online. Since the end of the years 2000, this rationalization for online communities is also known as Community Management. We formulate the hypothesis that community management policies spread to whole human activities on the web 2.0, and that community management policies rule the new knowledge mediations.

Ginger and Turmeric Essential Oils for Weed Control and Food Crop Protection

2019

Ginger and turmeric are two food ingredients that are in high demand due to their flavor and positive effects on health. The biological properties of these spices are closely related to the aromatic compounds they contain. The chemical compositions of their essential oils and their in vitro phytotoxic activity against weeds (Portulaca oleracea, Lolium multiflorum, Echinochloa crus-galli, Cortaderia selloana, and Nicotiana glauca) and food crops (tomato, cucumber, and rice) were studied. Forty-one compounds, accounting for a relative peak area of 87.7% and 94.6% of turmeric and ginger essential oils, respectively, were identified by Gas Chromatography&ndash

Microgastrinae (Hymenoptera: Braconidae) in the Forest State of Artikutza (Navarra: Spain): Diversity and Community Structure

2013

Microgastrinae is one of the largest subfamilies of the Braconidae with about 2,000 described species worldwide. These wasps are of enormous ecological interest due to their role in controlling the caterpillar populations. This study analyses diversity and community structure within the Microgastrinae in the Artikutza Forest, located in the Peñas de Aia Natural Park, western Pyrenees, Spain. The specimens were collected in two different habitats: mixed forest and beech forest. A total of 524 specimens, belonging to nine separate genera and 27 species were captured. Alpha, beta and gamma diversity were analyzed. Additionally, the relationship between Microgastrinae phenology and climatic con…

Polonica we wspomnieniach Zofii Kowalewskiej

2016

The present article focuses on Polish motifs in Sofya Kovalevskaya’s recollections. Kovalevskaya was a great 19th century Russian mathematician whose contributions were acknowledged throughout Europę during her lifetime. She was the first European woman to receive a doctorate in mathematics from the University of Gottingen, a professor at Stockholm University in Sweden, and the first female corresponding member of the Russian Academy of Sciences. Besides her scientific activities, Kovalevskaya was also a writer and publicist. She is the author of a number of novels, poems, a play and autobiographical Recollections of Childhood. In one of the chapters, entitled “Polish Uprising Recollections…

Essential oil crops for sustainable agriculture - A review

2009

Multifunctionality and diversification of farming systems, integration of agricultural practices both inter se and with the non-agricultural productive systems operating on the territory, biodiversity safeguards, and reduction in off-farm inputs, are key factors for all modern development strategies in agricultural areas. Such issues are valid worldwide, but are especially true in areas in which the cultivation of the more widespread and “classical” crops is constrained by factors of varying degree and importance. In Mediterranean areas, where many environmental and economic factors often reduce rural areas to marginal conditions, the search for new crop opportunities has become one of the …

Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards

2022

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…

Mercato digitale e sistema delle successioni mortis causa

2022

The work aims to examine the curvature impressed by the current order of the market and of the "algorithmic" society, centered on social network platforms, on principles and categories of classical hereditary law, putting the system of mortis causa succession into reaction with the matter of relationships and personal rights developed on the web, marked by the changes that shake the European and internal legal framework. The study is organized according to a tripartite scheme, which distinguishes the succession in contracts for the supply of digital services, from the transmission of rights on user-generated content and on the personal data of the deceased. To then keep a unity in the const…

Persistency of window dressing practices in the US repo markets after the GFC: The unexplored role of the deposit insurance premium

2022

We investigate whether the regulatory improvements made in the aftermath of the global financial crisis have been effective in limiting bank downward window dressing by means of repos in the United States. We find that a strict application of the Basel III regulation wipes out incentives to engage in window dressing to bolster the level of leverage Tier 1 ratio at quarter-end. We also show that the persistency of window dressing is related to the computation of the Federal Deposit Insurance Corporation assessment base, which motivates banks to engage in window dressing to reduce the deposit insurance premium.
