Self-Efficacy, Satisfaction, and Academic Achievement: The Mediator Role of Students Expectancy-Value Beliefs
2017
Although there is considerable evidence to support the direct effects of self-efficacy beliefs on academic achievement, very few studies have explored the motivational mechanism that mediates the self-efficacy–achievement relationship, and they are necessary to understand how and why self-efficacy affects students’ academic achievement. Based on a socio-cognitive perspective of motivation, this study examines the relationships among academic self-efficacy, students’ expectancy-value beliefs, teaching process satisfaction, and academic achievement. Its main aim is to identify some motivational-underlying processes through which students’ academic self-efficacy affects student achievement and…
Temporal dynamic of biofilms enhances the settlement of the central-Mediterranean reef-builder Dendropoma cristatum (Biondi, 1859).
2021
Abstract Research on marine invertebrate settlement provides baseline knowledge for restoration technique implementation, especially for biogenic engineers with limited dispersion ability. Previously, we determined that the maturity of a biofilm strongly enhances the settlement of the vermetid reef-builder Dendropoma cristatum. To elucidate settlement-related biofilm features, here we analyse the structure and composition of marine biofilms over time, through microscopic observations, eukaryotic and prokaryotic fingerprinting analyses and 16S rDNA Illumina sequencing. The vermetid settlement temporal increase matched with the higher biofilm coverage on the substratum and the reduction of th…
CONSERVATION NEEDS FOR THE VERMETID REEFS IN THE MEDITERRANEAN SEA
2015
Vermetid reefs are intertidal bioconstructions typical of many subtropical and temperate coastal areas worldwide. Distributed in the warmest waters of the Mediterranean Sea, the reefs are built by the vermetid gastropod Dendropoma petraeum and the coralline alga Neogoniolithon brassica-florida, two species included in the annexes of the Berna Convention. Vermetid reefs provide a wide set of ecosystem services, such as coastal protection from erosion, regulation of sediment transport and accumulation, serving as carbon deposit and increasing biodiversity at the intertidal level. Despite its vulnerability to several threats, such as pollution, spread of invasive species, ocean acidification a…
Akumulētā oglekļa daudzums Rīgas pilsētas mežaparku augsnēs.
2015
Bakalaura darba ietvaros veiktajā pētījumā astoņos Rīgas pilsētas mežaparku (Mežaparks, Anniņmuižas mežaparks, Bolderājas mežaparks, Juglas mežaparks, Biķernieku mežaparks, Šmerļa mežaparks, Bābelītes mežaparks un Ulbrokas mežaparks) augsnēs noteikts kopējais ogleklis. Pētījumā aprēķināts kopējais akumulētais oglekļa daudzums augsnes O/A horizontā un augsnes virsējā EB horizontā. Iegūtie dati attēloti kartoshēmās. Pētījumā secināts, ka mežaparkos 1577 ha lielā platībā, augsnes nedzīvajā zemsegā, A horizontā un minerālā EB horizonta pirmajos 10 cm ir akumulēts 118,7 tūkstoši tonnu kopējā oglekļa ar vidējo kopējā oglekļa saturu 62 t C ha-1. Visvairāk kopējais ogleklis – 26,1 tūkstoši tonnu, i…
Augšņu daudzveidîba un to ietekmējošie faktori Vidzemes augstienes morēnas paugurainē
2018
Bakalaura darba mērķis ir novērtēt augšņu īpašību izmaiņas morēnu paugurainē un izstrādāt priekšlikumus augšņu kartēšanas metodoloģijai atbilstoši Latvijas un starptautiskajai FAO WRB augšņu klasifikācijai. Bakalaura darbā atspoguļota jauna informācija par augšņu morfoloģiskajām, ķīmiskajām un fizikāli ķīmiskajām īpašībām morēnas pauguraines katēnā, kā arī analizēta augšņu īpašību maiņa augsnes katēnā. Lielu daļu Latvijas teritorijas aizņem paugurains reljefs, kur novērojama strauja augšņu īpašību maiņa. Dažādos novietojumos mainās vairāki vides faktori, to skaitā gruntsūdens līmenis, mikroklimats, veģetācija un citi faktori, kas kopumā ietekmē augsnes fizikāli ķīmiskās un ķīmiskās īpašības…

Le Quaternaire franc-comtois. Essai chronologique et paléoclimatique.
1982
Le but de ce travail est d'établir le cadre chronologique et paléoclimatique du Quaternaire en Franche-Comté à partir de l'étude des formations édifiées au cours de cette période.Deux grands types de dépôts ont été plus particulièrement étudiés: ·- Les remplissages karstiques d'avens, de porches de grottes et d'abris sous roche, donnant un éclairage intense, mais ponctuel, de l'environnement physique et biologique, grâce aux faunes abondantes et aux indices climatiques d'ordre sédimentologique.- Les dépôts glaciaires et paraglaciaires (moraines, fluvioglaciaires, glacio-lacustres) qui permettent de situer des coupures climatiques au cours du temps dans l'espace géographique étudié.L'étude d…
Linked data vocabularies for BIM
2019
Given the high interest in the field of BIM (Building Information Modeling) for Linked Data approaches over the last years, the article at hand presents an evaluation of the main Linked Data vocabularies available for the considered domain. First, Semantic Web layer architecture is presented, along with the 4 main principles of Linked Data. Second, each vocabulary is evaluated according to these 4 principles, while 2 additional ones are added in order to assess the licence associated with the vocabulary (open or not, specified or missing). An overall comparison among the considered vocabularies is also provided, thus helping in choosing which vocabulary to use in future Linked Data applicat…
Méthodes d'acquisition, de codage et d'analyse de profils sensoriels temporels
2004
National audience; La méthode de Temps-Intensité (TI) consiste à mesurer l’évolution de la perception de l’intensité d’un descripteur au fil du temps de la dégustation d’un produit. Lorsque plusieurs descripteurs sont étudiés (situation du profil sensoriel), cette méthode devient quasiment impraticable car elle nécessite une dégustation par descripteur. Cette communication se propose de synthétiser un ensemble de travaux visant à proposer des méthodes d’obtention de courbes des évolutions temporelles de plusieurs descripteurs simultanément. La première de ces méthodes, Dominance Temporelle des Sensations (DTS) [1], a permis de restituer assez fidèlement les courbes TI de 10 descripteurs pou…
Moringa oleifera supplemented foods in South Africa : A multidisciplinary approach combining consumer studies with physico-chemical and nutritional a…
2021
Malnutrition is a major challenge in South Africa (SA), particularly in Eastern Cape and Limpopo provinces, which are predominantly black and historically disadvantaged. This thesis aims to assess the potential of Moringa oleifera (MO) as a source of nutritional improvement in the diets of mothers and their children in these provinces. Known for its nutritional benefits, MO is a plant native to India, now cultivated in SA but not widely used for human nutrition. A two-part approach was followed in this thesis. The first part aims to understand how MO is perceived by consumers and how it can be integrated into the South African food repertory. A study of the knowledge, beliefs and consumptio…
