Biodiversity of Sourdough Lactic Acid Bacteria.

2010

Modern technology of baked goods largely uses sourdoughs because of the many advantages offered over baker’s yeast. Sourdough is characterized by a complex microbial ecosystem, mainly represented by lactic acid bacteria (LAB) and yeasts, whose fermentation confers to the resulting product its characteristic features such as palatability and high sensory quality. Raw materials used in baking are not heat-treated; thus, they bring their wild microorganisms to the production process. Investigation of the composition and evolution of microbial communities of sourdough and raw materials is relevant in order to determine the potential activities of sourdough microorganisms. LAB are the main facto…

Behind the scenes of artificial intelligence: a study of micro-work platforms in France

2019

Este artículo es una versión resumida del informe “Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?» This article is a summarized version of the report "Le Micro-travail en France. Derrière l’automatisation de nouvelles précarités au travail?" .; International audience; Micro-work internet services allocate small, standardized tasks of data generation and annotation to crowds of providers. The outputs are mainly used to produce artificial intelligence solutions. It is an exemplary instance of the “platformization” of the economy, and of the transformations of labour that digital technologies bring about. To uncover the conditions under which micro-wo…

Statistica Economica con R : : laboratorio di analisi statistica di dati economici tramite software R

2018

Il volume nasce dall'esperienza didattica dell'autore nell'ambito dei corsi di Statistica Economica erogati agli studenti di Statistica all'interno dell'Ateneo di Palermo. Il testo affronta alcuni dei principali temi della Statistica Economica in un approccio applicato con un esteso utilizzo del software open source R, oggi tra i pacchetti statistici in assoluto più diffusi ed utilizzati nelle università e nel mondo del lavoro. Il volume segue un taglio laboratoriale con una presentazione e discussione di alcune tecniche, metodi ed analisi statistiche di specifica utilità per il trattamento del dato economico. Il lettore viene dunque accompagnato durante l'esposizione con continui riferimen…

Stresa pārvārēšanas stratēģiju saistība ar subjektīvo labklājību un pašcieņu

2017

Pētījuma mērķis ir izpētīt stresa pārvārēšanas stratēģiju, subjektīvās labklājības un pašcieņas savstarpējās saistības. Pētījumā piedalījās 86 respondenti, vecumā no 18 līdz 41 gadam. Pašcieņas mērīšanai tika izmantota Rozenberga pašcieņas skala (Rosenberg self-esteem scale, (Rosenberg, 1965)), Latvijā adaptējusi Anika Miltuze, 1996.gadā; stresa pārvārēšanas stratēģiju mērīšanai - Stresa pārvarēšanas stratēģiju aptauja (The Coping Orientation of Problem Experience / COPE / Inventory, (Carver, Scheier, & Weintraub, 1989)), Latvijā adaptējusi Inna Petrova, 2009.gadā; un subjektīvās labklājības mērīšanai - skala “ Apmierinātība ar dzīvi” (Satisfaction With Life Scale; (Pavot, & Diener, 1993)).…

Pedagogu psiholoģiskās labbūtības saistība ar izturību un stresu darba vidē

2022

Pētījuma mērķis - analizēt pedagogu psiholoģiskās labbūtības, izturības un stresa darba vidē saistību un noteikt pedagogu labbūtību prognozējošos faktorus saistībā ar izturību un stresu darba vidē. Pētījuma jautājumi - vai ai pastāv saistība starp pedagogu psiholoģisko labbūtību, izturību un stresu darba vidē un kādi ir pedagogu psiholoģisko labbūtību prognozējošie faktori saistībā ar izturību un stresu darba vidē. Secinājumi: Pastāv statistiski nozīmīga cieša pozitīva korelācija starp pedagogu psiholoģisko labbūtību un izturību, bet negatīva korelācija starp psiholoģisko labbūtību un stresu darba vidē. Izturība ir nozīmīgākais pedagogu psiholoģisko labbūtību prognozējošais faktors. No iztu…

Student experiences of project-based learning in an analytical chemistry laboratory course in higher education

2020

Abstract This study describes students’ experiences in project-based learning (PjBL) incorporated as part of a revised undergraduate analytical chemistry laboratory course. We examined which phases were the easiest as well as the most challenging and what student skills developed during the research project. The research data were collected between 2016 and 2018 via two questionnaires. They were analyzed both quantitatively and qualitatively. One questionnaire focused on the whole course (in 2016–2018, n = 127) of which only the answers on the research project questions were analyzed. The other questionnaire focused on only the research project (in 2018, n = 42). Based on the results of our…

The Role of Surface Acting in the Relationship between Job Stressors, General Health and Need for Recovery Based on the Frequency of Interactions at …

2022

The aim of the study was to verify whether the frequency of face-to-face interactions with the public at work can reveal differences in how people react to emotional regulation demands. In particular, we investigated the mediating role of surface acting (a strategy of dealing with emotional dissonance) in the relationship between two typical job stressors (workload and mental load) and two outcomes closely related to work-related well-being: employees’ general health and the need for recovery. Prior studies investigating the detrimental effects of emotional dissonance mostly focused on service workers. However, in light of a survey conducted by the European Agency for Safety and Health at W…
