Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
Seguridad y ciudadanía en la España democrática. La Policía de Proximidad como ética aplicada
2018
El presente trabajo tiene carácter descriptivo y es consecuencia de años de servicio en políticas públicas de seguridad; esta experiencia personal ha pasado por el tamiz de la reflexión ética, y al escribirla hemos pretendido reconstruir esa experiencia de trabajo desde la perspectiva de una ética cívica. Esta voluntad de reconstrucción supone en cierto modo una “justicia reparadora” con los verdaderos protagonistas de esta historia: policías y vecinos, todos ciudadanos en un mismo escenario, la España constitucional, que han trabajado por la seguridad ciudadana y la libertad. La reconstrucción reflexiva de estas experiencias era una obligación implícita que debía ser cumplida. No podía dej…
Using AI to personalise emotionally appealing advertisement
2019
Personal data and information collected online by companies can be used to design and personalise advisements. This chapter extends existing research into the online behavioural advertising by proposing a model that incorporates artificial intelligence and machine learning into developing emotionally appealing advertisements. It is proposed that big data and consumer analytics collected through AI from different sources will be aggregated to have a better understanding of consumers as individuals. Personalised emotionally appealing advertisements will be created with this information and shared digitally using pragmatic advertising strategies. Theoretically, this chapter contributes towards…
Conscription of Network Business Models
2010
As enterprises focus increasingly on core competencies, the importance of collaboration and knowledge sharing between organisations is greatly enhanced. This article examines the development of knowledge sharing during the initial exploratory stages of an emerging business network. We demonstrate how the business model can serve as a tool for spanning organisational boundaries. Through developing a business model, network enterprises can learn to understand each other, create common concepts within their business network and evaluate feasibility of the endeavour. peerReviewed
Comparisons, Categories, and Labels: Investigating the North–South Dichotomy in Europe
2021
The paper presents genealogy-oriented analysis of how the Nordic model gained its dominant characterization as modern, advanced and superior to other European welfare models while Southern European countries came to be labelled laggards in the welfare domain. To illuminate the relational nature of these, and all, comparisons, the analysis accentuates how researchers, politicians, and civil servants alike designate Nordic and Southern European states, their societies, and their welfare models. The empirical analysis focuses on scholarly writings about welfare-state comparisons (1986–2017) and on European Union documents addressing cohesion policies (1986–2021). Analysis of the vocabulary and…
Stability of social support during school transitions: Associations with truancy and not completing upper secondary education in normative time
2022
Not completing upper secondary education is often presignaled by truancy from school. Student-perceived social support from family, peers, and teachers can prevent truancy and the risk of not completing education. However, prior studies have not focused on the stability of social support across school transitions. This longitudinal study of 1901 Finnish students examined the extent to which social support was stable or specific to primary, lower secondary, and upper secondary schools. Moreover, we examined whether support was associated with not completing upper secondary education in normative time and whether truancy mediated the relationship between support and not completing education. …
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…

Izņēmumu no personiska atbildības modeļa Latvijas un Eiropas Savienības konkurences tiesībās.
2018
Saskaņā ar ilgstošu Eiropas Savienības tiesas praksi konkurences tiesību efektīvas piemērošana pieprasa izmantot ekonomisko pieeju tiesību piemērošanā, kas cits starp paredz vairākās atkāpes no personiskā atbildības principa. Konkurences tiesības balstās uz ekonomisko pieeju, atbilstoši kurai sods par konkurences tiesību pārkāpumu jāadresē ekonomiskai vienībai, jeb tirgus dalībniekam. Atkāpes no personiskās atbildības principa Eiropas Savienības un nacionālo tiesu un konkurences uzraugu praksē kļuvuši par normālu parādību, kas izraisīja vairākās diskusijas par šādas pieejas piemērošanas niansēm un pieļaujamību. Līdz ar to darbs tiks veltīts izņēmumiem no personiskās atbildības principa Latv…
