Līderības stils kā noteicējfaktors starptautisko uzņēmumu digitālās transformācijas vadīšanā
2020
Bakalaura darbs ir veltīts starptautisko uzņēmumu digitālās transformācijas vadīšanas un līderības stila izpētei, par darba mērķi tiek izvirzīts digitālo transformāciju veicinošā stila noteikšana. Darbā tiek pētīti sekojoši koncepti: digitālā transformācija, pārmaiņu vadība, līderības stils. Par pētījuma analīzes pieeju darba autore izvēlās interpretatīvo pieeju un sekojošas darba metodes: zinātniskās literatūras un citu informācijas avotu izpēte, starptautisko uzņēmumu vadītāju intervija, starptautisko uzņēmumu darbinieku fokuss grupas intervija; pētījumā piedalās tikai uzņēmumi, kuros notiek digitālā transformācija. Īstenotā pētījuma rezultāti ļauj noteikt līderības stila nepieciešamās īp…
Developing a narrative of worth through participation in critical youth program in Wilmington, Delaware
2017
Positive relationships and having a counterspace can help marginalized youth develop a more positive sense of self and their lives as well as encourage them to promote justice in society. Challenging the youth with an employment program can help them create beneficial goals for their lives and work towards the benefit of others. The purpose of this study was to find whether critical youth work can support the youth to develop a critical consciousness and willingness to fight against oppression. The research examined the Streetleaders program in the lives of marginalized youth in the city of Wilmington, Delaware, the US. This qualitative research was built with eight open-ended interviews, c…
The linearized Calderón problem for polyharmonic operators
2023
In this article we consider a linearized Calderón problem for polyharmonic operators of order 2m (m ≥ 2) in the spirit of Calderón’s original work [7]. We give a uniqueness result for determining coefficients of order ≤ 2m − 1 up to gauge, based on inverting momentum ray transforms. peerReviewed
Association between socioeconomic factors and origin of hospital referrals among patients with oral cancer.
2022
The Brazilian Unified Health System (SUS) is responsible for offering free assistance to more than 100 million Brazilians, including treatment of oral cancer lesions. Considering that the Brazilian public system aids the most vulnerable population, this study analyzed whether the origin of hospital referrals of patients with oral cancer is associated with socioeconomic factors. A cross-sectional study was carried out from cancer hospital records of the National Cancer Institute (RHC-INCA), considering the primary locations (C00 to C06) diagnosed between 2016 and 2019. Data on gender, skin color (white and non-white), education (no schooling, incomplete or complete elementary education; high…
Net currents obtained from zero-average potentials in single amphoteric nanopores
2013
We have studied experimentally and theoretically the rectifying properties of a single asymmetric nanopore functionalized with amphoteric lysine groups and characterized the net current obtained with zero-average time dependent potentials. The pH-controlled rectification phenomena may be relevant to bio-electrochemistry, pH sensing and regulation, and energy conversion. (C) 2013 Elsevier B.V. All rights reserved.
Image classification based on 2D feature motifs
2013
The classification of raw data often involves the problem of selecting the appropriate set of features to represent the input data. In general, various features can be extracted from the input dataset, but only some of them are actually relevant for the classification process. Since relevant features are often unknown in real-world problems, many candidate features are usually introduced. This degrades both the speed and the predictive accuracy of the classifier due to the presence of redundancy in the candidate feature set. In this paper, we study the capability of a special class of motifs previously introduced in the literature, i.e. 2D irredundant motifs, when they are exploited as feat…
On the high-pressure phase stability and elastic properties ofβ-titanium alloys
2017
We have studied the compressibility and stability of different β-titanium alloys at high pressure, including binary Ti–Mo, Ti–24Nb–4Zr–8Sn (Ti2448) and Ti–36Nb–2Ta–0.3O (gum metal). We observed stability of the β phase in these alloys to 40 GPa, well into the ω phase region in the P–T diagram of pure titanium. Gum metal was pressurised above 70 GPa and forms a phase with a crystal structure similar to the η phase of pure Ti. The bulk moduli determined for the different alloys range from 97 ± 3 GPa (Ti2448) to 124 ± 6 GPa (Ti–16.8Mo–0.13O).

Recent progress on the superconducting ion source VENUS.
2012
The 28 GHz Ion Source VENUS (versatile ECR for nuclear science) is back in operation after the superconducting sextupole leads were repaired and a fourth cryocooler was added. VENUS serves as an R&D device to explore the limits of electron cyclotron resonance source performance at 28 GHz with its 10 kW gryotron and optimum magnetic fields and as an ion source to increase the capabilities of the 88-Inch Cyclotron both for nuclear physics research and applications. The development and testing of ovens and sputtering techniques cover a wide range of applications. Recent experiments on bismuth demonstrated stable operation at 300 eμA of Bi31+, which is in the intensity range of interest for hig…
