Monitoring Commercial Starter Culture Development in Presence of Red Grape Pomace Powder to Produce Polyphenol-Enriched Fresh Ovine Cheeses at Indust…
2021
Red grape Nero d’Avola cultivar grape pomace powder (GPP) was applied during fresh ovine cheese production in order to increase polyphenol content. Before cheeses were produced, the bacteria of a freeze-dried commercial starter culture were isolated and tested in vitro against GPP. Two dominant strains, both resistant to GPP, were identified. Thestarter culture was inoculated in pasteurized ewe’s milk and the curd was divided into two bulks, one added with 1% (w/w) GPP and another one GPP-free. GPP did not influence the starter culture development, since lactic acid bacteria (LAB) counts were 109 CFU/g in both cheeses at 30 d. To exclude the interference of indigenous LAB, the pasteurized m…
1,1prime-Binaphthyl-2-methylpyridinium-based peroxophosphotungstate salts: synthesis, characterization, and their use as oxidation catalysts
2009
A series of 1,1′-binaphthyl-2-methylammonium and pyridinium salts 6, 7, and 8 was synthesized through the coupling reaction of 2-(bromomethyl)-1,1′-binaphthalene (5) with the dendritic tetraallyl pyridinedicarbinol dendron 2 as well as triethylamine and 4-tert-butylpyridine. Tetraallyl pyridinedicarbinol dendron 2 was prepared by allylation of commercially available diethyl pyridine-3,5-dicarboxylate (1). The allylation of 2 with allyltrimethylsilane in the presence of boron trifluoride was unsuccessful, as tetraallyl pyridinedicarbinol trifluoroboron adduct 3 was obtained instead of expected hexaallylpyridine compound 4. The catalytic hydrogenation of allyl groups of the ammonium salt of 2…
El impacto de la política de visados sobre los flujos internacionales de turistas: Un análisis con datos de panel
2016
Using newly panel data on visa restrictions for the years 2000 and 2010 in a theory-grounded gravity model, we find a robust, causal negative impact of visa restrictions on international tourist flows. By destination, the detrimental impact of this type of barrier is observed for tourists going to developing countries (with the exception of East and South Asia), but not for those to developed ones. By country of origin of tourists, the impact of visa restrictions appears to be the same for tourists coming from developed and developing countries. These findings have important consequences in policy terms for tourism management at a regional level.
Usage des organisateurs anti-entropique dans les documents électroniques : approche expérimentale des fenêtres ponctuelles
1999
International audience; Les documents électroniques permettent de nombreuses manières d'organiser, de présenter et d'accéder à l'information. Une utilisation pertinente de ces options par les auteurs requiert une bonne connaissance des effets que ces choix ont sur la représentation cognitive et les traitements faits par l'utilisateur. Cette approche des documents électroniques, sur la base du concept de représentation mentale, fournit un cadre d'analyse des structures et signaux propres à ce type d'écriture. Parmi ces signaux que nous appelons « organisateurs para-linguistiques » pour les distinguer de leurs équivalents purement textuels, un ensemble est destiné à réduire l'entropie due à l…

Parāds nav brālis: 'Ātro kredītu' dimensijas, aizņemšanās prakses un to radītie efekti jauniešu vidū Latvijā
2015
Šis maģistra darbs pēta gados jaunus ātro kredītu klientus, kuri sastapušies ar problēmām tos lietojot. Tiek atklātas ne vien to motivācijas šī produkta lietošanai, bet arī indivīdu aizņemšanās prakses, parāda izpratne un parādsaistību efekts. Šī pētījuma mērķis ir izprast patērētāju attieksmes pret ātrajiem kredītiem, to izmantošanas iemeslus un sekas. Šajā darbā tiek argumentēts, ka parādsaistību slogs gados jauniem cilvēkiem rada ne vien finansiālas grūtības, bet arī emocionālu diskomfortu. Analizējot patērētāju attieksmes un ātro kredītu ņemšanas sekas, aplūkotas vairākas parāda dimensijas, tādejādi atklājot veidus kā parāds var tikt konceptualizēts un uz kādām ikdienas sfērām tas atstā…
Effects of Entrepreneurial Orientation and Passion for Work on Performance Variables in Sports Clubs
2021
Entrepreneurial orientation and passion for work have been widely studied due to their effects on the behaviour and attitude of management teams in the short- and long-term. However, despite the influences of these variables on the sustainability and survival of an entity, there is a gap when considering the effects of these two performance variables in sports organisations. Therefore, the main objectives of this study were to understand the influences of entrepreneurial orientation and passion for work on service quality and sporting performance. To this end, 199 Spanish non-profit sports clubs were analysed using instruments with good psychometric properties. Data analysis was carried out…
Neuropsychological Alterations in Children Affected by Obstructive Sleep Apnea Syndrome
2020
Sleep-related breathing disorders are a group of clinical conditions ranging from habitual snoring to obstructive sleep apnea syndrome (OSAS) during the lifespan. In children, other risk factors are represented by adenotonsillar hypertrophy, rhinitis, nasal structure alteration, cleft palate, velopharyngeal flap surgery, pharyngeal masses, craniofacial malformations, genetic syndrome (i.e. Down syndrome, Crouzon syndrome, and Apert syndrome), genetic hypoplasia mandibular (i.e. Pierre Robin syndrome, Treacher Collins syndrome, Shy-Drager syndrome, and Cornelia De Lange syndrome), craniofacial traumas, chronic or seasonal rhinitis, asthma, neuromuscular syndromes, brainstem pathologies (i.e.…
Rational Herding in Reward-Based Crowdfunding: An MTurk Experiment.
2020
Crowdfunding is gaining popularity as a way of financing social sustainable initiatives. We performed a controlled economic experiment in MTurk by simulating a crowdfunding platform and developed a theoretical model that rationalizes herding behavior. The experiment was designed to test and quantify the causal effects of revealing specific information to prospective backers: (i) the number of early contributors already financing the project and (ii) positive opinions of other backers versus those of experts. The results show that early contributions to the campaign and positive opinions of peers act as a reinforcing signal to potential backers and affect backers&rsquo
Coping Strategies against peer victimization: differences according to gender, grade, victimization status and perceived classroom social climate
2021
The Sustainable Development Goals (SDGs) include “Good Health and Well-being” (SDG3) and “Quality Education” (SDG4). Nevertheless, many students cannot achieve these goals if they suffer peer victimization at their schools, and intervention programs to reduce it are necessary. These programs should consider the possible differences in the coping strategies preferred by students according to some personal (e.g., gender, grade, victimization status) and contextual (e.g., perceived classroom social climate) factors to be more effective. Therefore, the objective of this study was to analyze the possible differences in the coping strategies preferred by students (ask a friend for help, ask a tea…
