Skolotāju pieredze vizuālo mediju izmantošanā kritiskās domāšanas un vizuālizpratnes veicināšanai angļu valodas stundās vidusskolā

2021

Maģistra darba mērķis bija izpētīt skolotāju pieredzi vizuālo mediju izmantošanā angļu valodas stundās vidusskolā skolēnu kritiskās domāšanas un vizuālizpratnes veicināšanai. Darba autore pievērsa arī īpašu uzmanību reklāmai kā vienam no vizuālo mediju veidiem, kas varētu veicināt iepriekšminēto prasmju attīstību. Autore ir pārliecināta, ka, atbilstoši izmantoti, vizuālie mediji var ne tikai bagātināt mācīšanās procesu caur to autentiskā materiāla formu un saglabāt skolēnu uzmanību stundās, bet arī veicināt dažādu skolēnu caurviju prasmju attīstību. Maģistra darbā dati tika iegūti, izmantojot trīs dažāda veida datu vākšanas metodes - anketēšanu, divas fokusgrupas diskusijas un divu ekspertu…

Konceptuālo metaforu lietojums kosmētikas produktu reklāmās

2016

Šī bakalaura darba mērķis bija noskaidrot konceptuālo metaforu koncepciju un funkcijas, izpētīt reklāmas būtību un analizēt populārākās konceptuālās metaforas izvēlētajās kosmētikas produktu reklāmās. Diskursa analīze tika izmantota kā pētījuma metode. Pētījums parādīja, ka galvenās konceptuālo metaforu funkcijas izvēlētajās reklāmās ir pievienot dramatisku efektu, attēlot vairākas nozīmes pieredzē un izcelt un saskaņot noteiktus mūsu pieredzes aspektus. Atlasītajās reklāmās tika atrasti sekojoši konceptuālo metaforu avota domēni: KARŠ/CĪŅA, VESELĪBA/MEDICĪNA, KUSTĪBA, LAIKA APSTĀKĻI, DABA un SEKSUĀLĀ PIEVILCĪBA. KARA/CĪŅAS koncepcija izrādījās visplašāk izmantota dotajā analizēto reklāmu k…

Rotational effects on the oscillation frequencies of newly born proto-neutron stars

2003

In this paper we study the effects of rotation on the frequencies of the quasi-normal modes of a proto-neutron star (PNS) born in a gravitational collapse during the first minute of life. Our analysis starts a few tenths of seconds after the PNS formation, when the stellar evolution can be described by a sequence of equilibrium configurations. We use the evolutionary models developed by Pons et al. (1999; 2001) that describe how a non rotating star cools down and contracts while neutrino diffusion and thermalization processes dominate the stellar dynamics. For assigned values of the evolution time, we set the star into slow rotation and integrate the equations of stellar perturbations in th…

Fault diagnosis of induction motors broken rotor bars by pattern recognition based on noise cancelation

2014

Current signal monitoring (CSM) can be used as an effective tool for diagnosing broken rotor bars fault in induction motors. In this paper, fault diagnosis and classification based on artificial neural networks (ANNs) is done in two stages. In the first stage, a filter is designed to remove irrelevant fault components (such as noise) of current signals. The coefficients of the filter are obtained by least square (LS) algorithm. Then by extracting suitable time domain features from filter's output, a neural network is trained for fault classification. The output vector of this network is represented in one of four categories that includes healthy mode, a 5 mm crack on a bar, one broken bar, …

Crónica sobre la problemática jurídica de los repartidores de comida a domicilio durante el estado de alarma

2020

En este artículo se realiza una crónica que analiza las implicaciones jurídico- laborales de los obstáculos y conflictos a los que se han enfrentado los trabajadores de las principales empresas de reparto de comida a domicilio durante los dos primeros meses de estado de alarma que, como consecuencia de la crisis sanitaria de la Covid-19, fue decretado en España el 14 de marzo de 2020. Partiendo del primigenio problema de los falsos autónomos, se abordan cuestiones como las dificultades para acceder a las prestaciones extraordinarias, la falta de medidas de protección de la salud, la reducción drástica de su remuneración, la carencia de titularidad del derecho de huelga o la prohibición de m…

Switching spatial scale reveals dominance-dependent social foraging tactics in a wild primate

2017

When foraging in a social group, individuals are faced with the choice of sampling their environment directly or exploiting the discoveries of others. The evolutionary dynamics of this trade-off have been explored mathematically through the producer-scrounger game, which has highlighted socially exploitative behaviours as a major potential cost of group living. However, our understanding of the tight interplay that can exist between social dominance and scrounging behaviour is limited. To date, only two theoretical studies have explored this relationship systematically, demonstrating that because scrounging requires joining a competitor at a resource, it should become exclusive to high-rank…

ANALYSIS OF THE IMPACT OF EXOGENOUS FACTORS ON THE FINANCIAL PERFORMANCE OF ROMANIAN COMMERCIAL BANKS LISTED ON BUCHAREST STOCK EXCHANGE

2015

The interest of both creditors and debtors of a credit institution on the performance registered by commercial banks imposed shaping high prudential standards designed to not upset the credit institution and to contribute decisively to increase their health profitability. On bank performance it shows a significant influence on many factors. The study focuses its attention on the impact of research that external factors are likely to print to financial rate of credit institutions (one of the classic indicators used to measure bank performance). The variables studied were represented by: - external factors: GDP, inflation and exchange rate leu-euro - considered to be independent variables and…

Cytotoxic necrotizing factor type 2 produced by virulent Escherichia coli modifies the small GTP-binding proteins Rho involved in assembly of actin s…

1994

Cytotoxic necrotizing factor type 2 (CNF2) produced by Escherichia coli strains isolated from intestinal and extraintestinal infections is a dermonecrotic toxin of 110 kDa. We cloned the CNF2 gene from a large plasmid carried by an Escherichia coli strain isolated from a lamb with septicemia. Hydropathy analysis of the deduced amino acid sequence revealed a largely hydrophilic protein with two potential hydrophobic transmembrane domains. The N-terminal half of CNF2 showed striking homology (27% identity and 80% conserved residues) to the N-terminal portion of Pasteurella multocida toxin. Methylamine protection experiments and immunofluorescence studies suggested that CNF2 enters the cytosol…

La chiesa e il convento di San Domenico a Cagliari nel XVI secolo.

Questa ricerca riguarda il convento di San Domenico a Cagliari e la riforma della fabbrica attuata nel corso del Cinquecento. Fondato nel borgo di Villanova nel versante est del castello di Cagliari nella seconda metà del XIII secolo, il convento di San Domenico raggiunse la sua massima espansione a partire dagli anni sessanta del XVI secolo, in seguito probabilmente all’introduzione nel convento della riforma domenicana. Le riforme spirituali e materiali del convento fecero parte di più vasto movimento di rinnovamento che coinvolse su larga scala il panorama sardo nel secondo Cinquecento, dovuto a molteplici fattori tra cui il riformismo monarchico di Filippo II e le riforme religiose avvi…

RIFIUTO A CONTRARRE E DIRITTO ANTITRUST UNA COMPARAZIONE TRA GLI ORDINAMENTI ITALIANO, EUROPEO E STATUNITENSE

Il lavoro presentato si prefigge lo scopo, muovendo dagli sviluppi della legislazione nazionale e comunitaria, ed alla luce dell’esperienza nordamericana, di chiarire in quali casi il rifiuto a contrarre costituisca uno strumento diretto ad eliminare la concorrenza o, più ampiamente, a pregiudicare il diritto di contrarre di chi aspiri ad instaurare rapporti commerciali con un’impresa in posizione dominante sul mercato. Gli obiettivi perseguiti sono quelli di ricondurre ad unità il concetto di essential facility nella più ampia tematica del rifiuto di contrarre, o di contrattare, ovvero del refusal to deal or to supply. In un’epoca caratterizzata dalla crescente concentrazione del potere ec…
