Successful SME web design through consumer focus groups
2011
Purpose – The purpose of this research is to pursue two major objectives. First, to identify the key design variables for building successful transactional SME (Small Medium Enterprises) websites. Second, the transactional relevance of each key design variable is tested in order to establish priorities.Design/methodology/approach – The present paper is developed through seven consumer focus groups. Two approaches were used: an ethnographic summary of each focus group (qualitative approach) and a systematic coding procedure (quantitative approach).Findings – The findings indicate that a transactional website should have three main strong points: it must be secure; price information should be…
Internal vs. external R&D teams: Evidences from the Italian wine industry
2021
R&D teams' internationalization attracts interests from different research-streams. However, the decision on what type of R&D structure is more convenient to invest in may differ, based on several factors, such as risk-taking propensity and internal resource availability. With an aim to enrich the extant literature and to provide practical insights for managers working in the wine industry, this case study explores the determinants of an Italian family-owned winery that attempts to keep a balance between its internal and external R&D teams' decision, using an integrated theoretical framework based on the transaction costs and the resource-based view theory. The optimal R&D s…
Structural differences of prebiotic oligosaccharides influence their capability to enhance iron absorption in deficient rats
2014
This study evaluates the influence of novel galacto-oligosaccharides derived from lactulose (GOS-Lu), kojibiose or 4′-galactosyl-kojibiose in hematological parameters of Fe homeostasis using Fe-deficient animals. Liver TfR-2, IL-6, NFκB and PPAR-γ expression (mRNA) were also determined by RT-qPCR analyses, and active hepcidin peptide production and short chain fatty acids by LC coupled to MS/MS or UV detection. Feeding animals with GOS-Lu or kojibiose together with FeCl3 increased hemoglobin (Hb) production (by 17%) and mean Hb concentration into erythrocytes relative to animals administered with FeCl3 alone (14.1% and 19.7%, respectively). Animals administered with prebiotics showed decrea…
Microbial Dynamics between Yeasts and Acetic Acid Bacteria in Kombucha: Impacts on the Chemical Composition of the Beverage.
2020
Kombucha is a traditional low-alcoholic beverage made from sugared tea and transformed by a complex microbial consortium including yeasts and acetic acid bacteria (AAB). To study the microbial interactions and their impact on the chemical composition of the beverage, an experimental design with nine couples associating one yeast strain and one AAB strain isolated from original black tea kombucha was set up. Three yeast strains belonging to the genera Brettanomyces, Hanseniaspora, and Saccharomyces and three strains of Acetobacter and Komagataeibacter species were chosen. Monocultures in sugared tea were analyzed to determine their individual microbial behaviors. Then, cultivation of the ori…
Skolotāju gatavība īstenot kompetenču pieejā balstītu vispārējās izglītības saturu pamatizglītības posmā
2018
Maģistra darbā tiek pētīta un analizēta šodien ļoti aktuālā tēma izglītībā: kompetenču pieejā balstīts mācību satura izklāsts. Darbā tiks skatīta tieši skolotāju gatavība īstenot jauno kompetenču pieeju. Medijos un ikdienā izskan daudz un pretrunīgas informācijas, lai iegūtu objektīvus datus par skolotāju gatavību īstenot kompetenču pieejā balstītu vispārējās izglītības saturu pamatizglītības posmā tika veikts kvantitatīvs un kvalitatīvs pētījums. Pētījuma mērķis ir izpētīt pedagoģiskos nosacījumus kompetenču pieejas īstenošanai mācību procesā. Maģistra darbs sastāv no 3 daļām. Pirmajā daļā tiek izzināta un analizēta teorētiskā informācija, skaidrots kompetenču jēdziens, kā arī tiek skatīti…
Kriminālprocesa vienkāršotie veidi
2016
Bakalaura darbā “Kriminālprocesa vienkāršotie veidi” tika pētīti kriminālprocesa vienkāršotie veidi Latvijā. Vienkāršotie veidi tika salīdzināti ar Igaunijas vienkāršotajiem kriminālprocesa veidiem. Pētīti tika kriminālprocesa vienkāršoto veidu priekšnoteikumi, termiņa regulējums, prakse, kurā parādās, kad visbiežāk tiek pielietots kriminālprocesa vienkāršotais veids un noziedzīgie nodarījumi, par kuriem var piemērot vienkāršoto kriminālprocesu. Autore konstatē, ka Latvijā ilgie tiesvedības termiņi neļauj lietas izskatīt saprātīgā termiņā, līdz ar to bieži vien pārkāpjot apsūdzētā tiesības, kas nonāk pie rezultāta, ka Latvija tiek iesūdzēta Eiropas Cilvēktiesību tiesā. Lai paātrinātu un vie…
Impact of oxidoreduction potential and of gas bubbling on rheological properties of non-fat yoghurt
2010
International audience; The aim of this work was to study the effect of different gaseous conditions on the physico-chemical properties of yoghurt. Four conditions of oxidoreduction potential (Eh7), +433 mV (milk gassed with air), +405 mV (ungassed milk), +283 mV (milk gassed with N2) and −349 mV (milk gassed with N2–H2) were applied to milk. The rheological properties and microstructure of these yoghurts were determined by measuring apparent viscosity, whey separation (WS) and using confocal laser scanning microscopy. Exopolysaccharide (EPS) production by lactic acid bacteria (LAB) was also studied, and production was increased for extreme Eh7 values: the highest values were obtained for a…
La collezione antiquaria di libri, incisioni e disegni del Musac a palazzo La Rocca, Ragusa Ibla
2017
LA COLLEZIONE ANTIQUARIA DI LIBRI, INCISIONI E DISEGNI DEL MUSAC A PALAZZO LA ROCCA, RAGUSA IBLA-La costituzione di un Museo di Storia dell’Architettura e della Costruzione nel Mediterraneo (Musac), allestito presso il palazzo La Rocca a Ragusa Ibla, in prossimità del duomo di San Giorgio, dispone di un interessante patrimonio antiquario composto da libri rari, trattati, incisioni e disegni. La collezione, che si è costituita nel tempo, è in buona parte dovuta ad acquisizioni ottenute con progetti europei cui ha partecipato il Dipartimento di Architettura di Palermo (Darch) e a un consistente gruppo di disegni e incisioni di collezioni private, depositate nella raccolta. Questo materiale et…
Educare il bambino alla vita interiore. La lezione di Maria Montessori nel tempo della post-democrazia
2014
Maria Montessori’s pedagogy of interiority carried out in the “Houses of Children” is relevant to the postmodern age. By focusing on the care of the child’s inner life, Montessori’s lesson offers the new generations authentic religious practices, thus responding to the new, increasingly widespread, need for sacred. On this wake, contemporary pedagogy is re-launching childhood as a new resource for the adult, endeavouring to transform the environments where education takes place into laboratories of peace and democracy.
Origines des levures Saccharomyces et non-Saccharomyces présentes dans le moût : Vignoble ou cuverie ?
2017
International audience; Les levures de l’espèce Saccharomyces cerevisiae ont longtemps été considérées comme les seules responsables du processus de fermentation. On sait aujourd’hui que différentes espèces de levures Saccharomyces et non-Saccharomyces (NS) sont présentes dans les moûts et qu’un certain nombre d’entre elles participe à la fermentation alcoolique (FA). Bien qu’il soit aujourd’hui largement admis que les principales sources de levures dans le moût de raisin sont les baies de raisin et le matériel de vinification (Fleet et Heard, 1993 ; Mortimer et Polsinelli, 1999) (figure 1), la part apportée par chacune de ces deux sources est encore mal définie. De plus, d’autres sources p…
