Continuous Requirements Risk Profiling in Information Systems Development

2015

With the increasing adoption of agile, lean, and iterative development methods, information systems development (ISD) has become continuous, meaning that system development moves rapidly from release to release. This means that work practices and challenges that practitioners face have changed. Despite these changes, requirements development is still critical in ISD. However, IS literature is silent on how to manage requirements-related risks in the practice of continuous IS development. To fill this gap, we propose a continuous requirements risk profiling method. The study is informed by design science research methodology, and we apply focus group interviews and a Delphi study for data co…

Identification of mycorrhiza-regulated genes with arbuscule development-related expression profile

2004

Suppressive subtractive hybridisation was applied to the analysis of late stage arbuscular mycorrhizal development in pea. 96 cDNA clones were amplified and 81, which carried fragments more than 200 nt in size, were sequence analysed. Among 67 unique fragments, 10 showed no homology and 10 were similar to sequences with unknown function. RNA accumulation of the corresponding 67 genes was analysed by hybridisation of macro-arrays. The cDNAs used as probes were derived from roots of wild type and late mutant pea genotypes, inoculated or not with the AM fungus Glomus mosseae. After calibration, a more than 2.5-fold mycorrhiza-induced RNA accumulation was detected in two independent experiments…

Regulation of type 1 fimbriae synthesis and biofilm formation by the transcriptional regulator LrhA of Escherichia coli

2005

Type 1 fimbriae ofEscherichia colifacilitate attachment to the host mucosa and promote biofilm formation on abiotic surfaces. The transcriptional regulator LrhA, which is known as a repressor of flagellar, motility and chemotaxis genes, regulates biofilm formation and expression of type 1 fimbriae. Whole-genome expression profiling revealed that inactivation oflrhAresults in an increased expression of structural components of type 1 fimbriae.In vitro, LrhA bound to the promoter regions of the twofimrecombinases (FimB and FimE) that catalyse the inversion of thefimApromoter, and to the invertible element itself. TranslationallacZfusions with these genes and quantification offimEtranscript le…

Pricavy-Preserving Aspects for Data Mining in ICT Services

The steady adoption of systems for profiling users behavior, collecting and critically interpreting as much information as possible about likes and dislikes, interests and habits of Internet residents and generic services consumers have rapidly become some of the hottest keywords within networking research community. Indeed, mining information about users behavior is an advantage for both service providers and service customers: on one side, providers can improve their revenues by focusing on the most successful features of their services, while on the other side, users can enjoy services which reflect closer their specific needs. There are many examples of user profiling applications. Inte…

Operāciju māsu prakses ietekmējošie faktori dažādos ķirurģiskos profilos

2020

Tēmas aktualitāte-Operācijas zāle ir viena no plašākajām darba vietām, kur operācijas māsas saskaras ar visiem ietekmējošiem faktoriem – bioloģiskiem, ķīmiskiem, fiziskiem, psiholoģiskiem un ergonomiskiem. Uz viņu var iedarboties viens faktors vai dažādu faktoru kopums. Veselības aprūpes vides dinamiskais raksturs prasa, lai operācijas māsa praksē pielietotu zināšanas un kompetences, lai kvalitatīvi pildītu savus darba pienākumus un sniegtu klientam kvalitatīvus pakalpojumus. Līdz ar to, operāciju māsas ir pakļautas praksi ietekmējošiem faktoriem dažādos ķirurģiskos profilos, ko nes līdzi vide , kurā tā strādā. Ja šie faktori tiek atstāti bez uzmanības laika gaitā parādīsies operācijas māsā…
