The influence of organisational facilitating conditions and technology acceptance factors on the effectiveness of virtual communities of practice
2019
The present study aimed to examine the influence of facilitating conditions on the effectiveness of a Virtual Community of Practice. To do so, we first analysed the influence of facilitating condit...
Politics of Humanitarianism: The Ahmadiyya and the Provision of Social Welfare
2020
Ahmadi Muslims have combined local contributions and financial support from overseas to support various development projects since the 1920s when they started their mission activities in West Africa. The chapter outlines contemporary social welfare activities of the Ahmadiyya Muslim Community in Ghana and Burkina Faso. Humanitarian aid provided by the Ahmadiyya Muslim Community and its NGO Humanity First is one of the issues favouring public recognition as well as interreligious dialogue to which the Ahmadis are equally strongly committed. Most of the donations for Humanity First come from members of the Ahmadiyya community, as zakat or sadaqa donations. Public recognition is particularly i…

Reliability and effectiveness of Ellenberg’s indices in checking flora and vegetation changes induced by climatic variations
2001
Two methods are proposed to assess the significance of time-spanned local variations of Ellenberg’s indicator values in floristic and phytosociological data sets respectively. Both methods are based on frequencies and averages of the indicator values within and among data sets. Main goal of proposed methods is to determine the threshold above which the observed variations are to be considered significant. In order to relate the observed floristic variations to recent climatic changes, attention was focused on the Ellenberg’s indices dealing with the main climatic variables: heliophany, temperature and precipitation. Study-cases from Zannone Island (Pontine Archipelago, Mediterranean region)…
Multi-Temporal Soil Salinity Assessment at a Detailed Scale for Discriminating Halophytes Distribution
2016
A multi-temporal survey of soil salinity in a salt lake, recolonized by halophytes, was performed using electromagnetic induction (EMI) providing volume integrated values of soil apparent electrical conductivity (ECa). Inventories of plant communities were recorded according to the Braun-Blanquet method. In each of six areas monospecific with Suaeda vermiculata, Suaeda vera, Sarcocornia fruticosa, or Arthrocnemun macrostachyum, ECa was measured intensively in two seasons. Mean and range of ECa differ for each plant community. Soil was sampled in the six areas and analyzed for ion composition of the soil saturated paste extract. The electrical conductivity of the saturated paste extract (ECe…
Ecological aspects of plants inhabiting Mediterranean cliffs. Challenges and prospects of life in vertical environments
2021
[ES] Esta tesis investiga las oportunidades, desafíos y limitaciones para la investigación en el campo de la ecología vegetal, en el contexto de los acantilados mediterráneos. En concreto, las especies casmofiticas, cuyos hábitats naturales se caracterizan por su acusada pendiente. Las laderas de las montañas de piedra caliza en la proximidad del mar, en la parte central y occidental del área mediterránea se consideran objetos de estudio. Los estudios se llevaron a cabo en los cinturones costeros de montaña de las costas del noroeste de Sicilia y la costa diánica en la Comunidad Valenciana. El primer capítulo, titulado "The complexity of environmental factors: cliff microclimate", investiga…
Novedades y consideraciones sobre el género Centaurea L. en la flora valenciana
2008
Se realizan algunas reflexiones sobre las especies valencianotarraconenses de Centaurea sect. Willkommia, grupo que actualmente está conformado por seis táxones en dicho territorio. A partir del estudio de numeroso material que cubre la mitad norte de la provincia de Valencia y la totalidad de Castellón, se revisan dichos táxones y se realiza una nueva propuesta en la que se describen dos nuevas especies: C. aguilellae (de las comarcas del centro-norte de Valencia) y C. fabregatii (de las comarcas del centro-este de Castellón). Novelties and considerations on Centaurea L. concerning the Valencian flora (eastern Spain): Data are reported on the Valencian-Tarraconensian (E of Spain) species o…
Mobilteknologi til videokommunikasjon ved trygghetsalarmer
2007
Masteroppgave i informasjons- og kommunikasjonsteknologi 2007 – Høgskolen i Agder, Grimstad Denne rapporten behandler bruk av mobiltelefoner som alarmsentral for hjemmeboende brukere. Studien legger vekt på de forskjellige mobile netts egenskaper og begrensninger som alarmbefordrer. Ønske om videotelefoni som alarm behandles og det foreslås løsninger for å ivareta dette uten å gå på akkord med sikkerhet. Juridiske sider med alarmer og videobilder behandles ut fra to ulike scenario avhengig av om hjelpere er offentlige eller private. Studien er gitt som en del av interregIII prosjektet Grensebroen Arena sin satsning innen emnet “Et år til hjemme” rettet mot eldre hjemme- boende. Prosjektet h…
Towards chemical communication between gated nanoparticles.
2014
The design of comparatively simple and modularly configurable artificial systems able to communicate through the exchange of chemical messengers is, to the best of our knowledge, an unexplored field. As a proof-of-concept, we present here a family of nanoparticles that have been designed to communicate with one another in a hierarchical manner. The concept involves the use of capped mesoporous silica supports in which the messenger delivered by a first type of gated nanoparticle is used to open a second type of nanoparticle, which delivers another messenger that opens a third group of gated nanoobjects.We believe that the conceptual idea that nanodevices can be designed to communicate with …
COGNITIVE MOBILIZATION IN PLANNING CONFLICT. Values and democratic implications in two southern-Europe insurgent practices.
La tesi sostiene che, mentre molte teorie di pianificazione si sono concentrate sulle differenze, il multiculturalismo e risoluzione dei conflitti sociali, non c'è ancora sufficiente approfondimento su come queste differenze possano restare profondamente irrisolte e come questa debolezza possa essere fortemente legata a razionalità contrastanti e a una sorta di “slittamento dei livelli di senso” o “equivoci” cognitivi tra i soggetti coinvolti (Bourdieu e Wacquant, 1992). Soprattutto in termini di conflitti urbani espliciti, generati non da opposti interessi economici o differenti volontà politiche, ma semplicemente da differenti background culturali e comportamentali, il livello cognitivo d…
