Consumers' perceptions of mobile banking continuous usage in Finland and South Africa
2015
This study examines continuous usage behaviour related to mobile banking (m-banking) among consumers living in Finland (FI) and South Africa (ZA). The study investigates three post-adoption behavioural consequences - namely, trust, satisfaction and word of mouth. Using purposeful sampling techniques, we found that trust plays a significant role in promoting continuous usage of m-banking. In general, the respondents reported high levels of trust in m-banking technology and were satisfied with the m-banking application and services. In addition, convenience, user friendliness and speed emerged as the main sub-topics related to satisfaction. In most cases, the convenience of using m-banking do…
Supported liquid membrane extraction with single hollow fiber for the analysis of fluoroquinolones from environmental surface water samples
2010
Abstract In this work, the simple analytical method for the determination of four fluoroquinolone antibiotics: ciprofloxacin, enrofloxacin, norfloxacin and danofloxacin, in environmental surface water samples is described. Sample pretreatment step was performed by the application of a technique based on supported liquid membrane extraction with the configuration of single hollow fiber (HF-SLM). The HPLC system with diode array detection was used for final analysis of studied analytes. Various parameters affecting the extraction efficiency during HF-SLM enrichment, such as type of membrane diluent, pH of donor (sample) and acceptor phases, as well as an enrichment time and salt content of sa…
Current issues of labour law during the Covid-19 pandemic.
2021
Covid-19 pandēmija ir smags pārbaudījums visiem – gan darba ņēmējiem, gan darba devējiem. Pandēmijas laikā daudzu uzņēmumu darbība ir faktiski apturēta, savukārt darba devēju pienākumi pret darbiniekiem ir palikuši, tāpēc bakalaura darba “Aktuālākie darba tiesību problēmjautājumi Covid-19 pandēmijas laikā” ietvaros konstatēti un analizēti svarīgākie jautājumi, kuri radušies uzņēmumu darbības ierobežojumu dēļ. Darba ietvaros analizēti gan jautājumi, kas saistīti ar iespēju turpināt darba tiesiskās attiecības ar grozītiem noteikumiem, gan jautājumi, kad darba tiesisko attiecību turpināšana nav iespējama. Tāpat analizēta aktualitāte - attālinātais darbs, tā piemērošana, ar to saistītie problēm…
Darba samaksa un darba samaksas sistēmas izpēte uzņēmumā SIA "ABC"
2020
Diplomdarba “DARBA SAMAKSA UN DARBA SAMAKSAS SISTĒMAS IZPĒTE UZŅĒMUMĀ SIA “ABC”” mērķis, pamatojoties uz darba samaksas teorētiskajām atziņām, identificēt normatīvajos aktos un pētāmajā uzņēmumā SIA “ABC” nepilnības un minēt priekšlikumus to novēršanai. Diplomdarbā ir izpētīti Latvijas normatīvie dokumenti, ekonomiskā literatūra, statistiskie dati un uzņēmuma SIA “ABC” nepublicētie materiāli, kā arī veikti praktiski aprēķini. Diplomdarbā izstrādāšanas gaitā autore konstatē, ka darba samaksas sistēma ir cieši saistīta ar likumdošanu un cilvēku izpratni par atalgojumu. Diplomdarba autore konstatēja virkni nepilnību normatīvajos aktos un uzņēmumā SIA “ABC”, un izstrādāja priekšlikumus to novēr…
Attention Check Items and Instructions in Online Surveys: Boon or Bane for Data Quality?
2019
In this paper, we examine rates of careless responding and reactions to detection methods (i.e., attention check items and instructions) in an experimental setting based on two different samples. First, we use a quota sample (with monetary incentive), a central data source for internet-based surveys in sociological and political research. Second, we include a voluntary opt-in panel (without monetary incentive) well suited for conducting survey experiments (e.g., factorial surveys). Respondents’ reactions to the detection items are analyzed by objective, nonreactive indicators (i.e., break-off, item non-response, and measurement quality), and two self-report scales. Our reaction analyses rev…
Toward fast and accurate emergency cases detection in BSNs
2020
International audience; In body sensor networks (BSNs), medical sensors capture physiological data from the human body and send them to the coordinator who act as a gateway to health care. The main aim of BSNs is to save peoples' lives. Therefore, fast and correct detection of emergencies while maintaining low-energy consumption of sensors is essential requirement of BSNs. In this study, the authors propose a new adaptive data sampling approach, where the sampling ratio is adapted based on the sensed data variation. The idea is to use the modified version of the cumulative sum (CUSUM) algorithm (modified CUSUM) that they previously proposed for wireless sensor networks to monitor the data v…
Osseointegration of miniscrews: a histomorphometric evaluation.
2007
SUMMARY Mini-implants and miniscrews are commonly used in orthodontics to provide additional temporary intraoral anchorage. Partial osseointegration represents a distinct advantage in orthodontic applications, allowing effective anchorage to be combined with easy insertion and removal. This article reports the histomorphometric fi ndings of the osseointegration of bracket screw bone anchors (BSBAs). In an experimental animal study, four BSBAs were inserted in the alveolar process of the lower jaw in each of fi ve male beagle dogs, aged 6.5 months from the same mother. Eleven screws were lost during the study, nine of them due to lack of primary stability. One screw was removed at the end of…
Familia, profesorado e iguales: claves para el apoyo a las víctimas de acoso escolar
2011
ResumenEl objetivo del presente estudio fue analizar las diferencias en ajuste psicológico en víctimas de acoso escolar en función de la calidad de sus relaciones con padres, profesores e iguales. En concreto, se compararon cuatro indicadores de ajuste psicológico (autoestima, ánimo depresivo, soledad y percepción de estrés) en víctimas con buena o mala comunicación con la madre, buena o mala comunicación con el padre, alta o baja percepción de ayuda del profesor, y alta o baja identificación con su grupo de iguales. La muestra inicial estuvo compuesta por 1795 adolescentes, entre 11 y 18 años (M=14.2, DT=1.68). Los resultados indicaron que las víctimas que mantenían mejores relaciones soci…
Flow injection near-infrared determination of ethanol in chloroform
1995
A simple and direct flow injection (FIA) procedure has been developed for the determination of the stabilizing agent ethanol in chloroform samples. The procedure is based on the use of the absorbance band of ethanol in the near-infrared (NIR) region at 2272 nm, measured in front of a reference sample of chloroform stabilized with amylene. The method developed provides a limit of detection of 0.0045% (v/v) and a dynamic range until 10% (v/v) with a typical variation coefficient of 0.4% for six independent analysis of a real sample containing approximately 1% (v/v) of ethanol. The sample injection frequency allowed by the method is 78 h−1.
