Legacy Effects of Contrasting Long-Term Integrated Weed Management Systems
2022
To reduce reliance on herbicides and maintain crop productivity, integrated weed management (IWM) seeks to optimize synergies between diverse sets of weed management practices combined at the cropping system scale. Nevertheless, data on weed community response to the long-term implementation of IWM practices remain scare. Here, we assessed the effects of four IWM systems with contrasting objectives and practices (S2: transition from superficial tillage to conservation agriculture; S3: no-mechanical weeding; S4: mixed mechanical and chemical weeding; S5: herbicide-free; all with 6 year rotations) compared to a conventional reference (S1: herbicide-based with systematic plowing and a 3 year r…
Understanding the sense of community and continuance intention in virtual communities: The role of commitment and type of community
2019
Virtual communities (VCs) have become essential in current organizations and society, and so their sustainability is a topic of interest for researchers and practitioners. We focus on the sense of virtual community (SoVC) and commitment as relevant antecedents in achieving the success and maintenance of different types of VCs (communities of interest, virtual learning communities, and virtual communities of practice). Specifically, this study examines a moderated mediation model in which the type of virtual community moderates the indirect effect of a SoVC on the intention to continue through the perceived commitment of the users of the VC. The sample consists of 299 members of Virtual comm…
Chimpanzees surviving in a fragmented high‐altitude forest landscape of the Congolese Albertine Rift
2021
This paper documents a community of eastern chimpanzees (Pan troglodytes schweinfurthii Giglioli, 1872) inhabiting three relict forest fragments situated on the Lake Albert escarpment, down the Ituri highlands, of eastern Democratic Republic of the Congo (DRC). The area explored had a combined forested surface of ±18.15 km2 in 2017, shrinking by 1.2% per year between 2010 and 2015. Between 2015 and 2017, we found 160 chimpanzee nests along 37.6 km of pilot walks, some up to 2,000 m altitude. Another 123 nests logged along 6.7 km transects led to an estimate of chimpanzee density of 4.62 weaned individuals per square kilometer of forest habitat. Camera‐trap images and direct observations rev…

Vegetation series as a marker of interactions between rural settlements and landscape: new insights from the archaeological record in Western Sicily
2020
[EN] Plant communities are complex and dynamic elements of the landscape, intertwined with both natural factors and human activities. Vegetation series reflect the environmental characteristics of the landscape, but also the anthropic impact, one of the exogenous forces that most profoundly affects the landscape formation process. This paper aims to investigate the interactions between long-term human settlement catchment areas and vegetation series. The case study area of the Sicani Mountains (Central-Western Sicily) proved to be an ideal place to perform GIS-based spatial analysis in order to compare a data set of rural archaeological sites and land units created through the mapping of ve…
Territori sensibili. La Trasversale sicula e la rete dei Centri minori rurali in Sicilia
2021
La ricerca sui processi di spopolamento e di abbandono delle piccole città è essenziale per agire sulla situazione attuale e sulle sue prospettive proponendo nuovi scenari, sperimentando metodologie d'azione, fornendo formazione a professionisti, e lancio di opportunità di investimento. In questi luoghi, il paesaggio si intreccia con il mito, alimentando le connessioni tra storia antica e storia recente, da un lato, e sostenendo l'ipotesi di una trasformazione anche minima del paesaggio attraverso variazioni e interpretazioni di ciò che esiste, dall'altro. La riprogettazione del territorio della Trasversale Sicula coniuga situazioni materiali e immateriali e immaginari che trovano nella ret…
Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
Labile nitrogen, carbon, and phosphorus pools and nitrogen mineralization and immobilization rates at low temperatures in seasonally snow-covered soi…
2006
Surface mineral horizons from four ecosystems sampled in the northwestern Italian Alps were incubated at −3 and +3°C to simulate subnivial and early thaw period temperatures for a seasonally snow-covered area. The soil profiles at these sites represent extreme examples of management, grazed meadow (site M) and extensive grazing beneath larch (site L) or naturally disturbed by avalanche and colonized by alder (site A) and the expected forest climax vegetation beneath fir (site F). Changes in labile pools of nitrogen (N) and phosphorus (P) were active at all sites at both temperatures during 14 days of laboratory incubation. Ammonium was the dominant inorganic form of total dissolved N (TDN),…
Społeczne uwarunkowania rozwoju ekonomii społecznej w regionalnej społeczności (na przykładzie Opolszczyzny)
2015
The aim of my article is to give an analysis of selected social factors that have influenced the implementation of the Opole Program for Social Economy Development, which was created to answer the needs and problems of the region. The resources of human and social assets of disadvantaged groups in Opole region, which are the key to social economy projects success as a regional and local development factor, have been found to be insufficient and limited (transmission of poverty, welfare dependency, negative attitudes towards work). It is for these reasons that the success of the program will be above all determined by the actions taken to raise the level of knowledge and public awareness not…
