Dzimtes dualitātes: Sieviešu pašpalīdzības kursu gadījums Rīgā
2019
Šajā maģistra darbā tiek analizēts kursu gadījums Rīgā, kas māca sievietēm, kā kļūt sievišķīgākām un dzīvot saskaņā ar noteiktiem sievišķības principiem, lai uzlabotu savu dzīvi un attiecības, ar mērķi padziļināt antropoloģisko izpratni par to, kā dzimte tiek konstruēta un izdzīvota. Šis pētījums skaidro, kā šajos kursos dzimte tiek dabiskota un balstīta dualitātēs, kādas īpašības tiek piedēvētas vīrišķībai un sievišķībai, un kāpēc sievietes uzskata par svarīgu mācīties par sievišķību un dzīvot saskaņā ar sievišķības principiem. Pētījumā tiek secināts, ka šie kursi ir balstīti postsociālisma, postfeminisma un neoliberālisma kontekstos, un tie aicina sievietes mainīt un attīstīt sevi, lai bū…
Experimental Study of the Stage-Discharge Relationship for an Upstream Inclined Grid with Longitudinal Bars
2013
AbstractIn this paper, the outflow process of an upstream inclined grid with longitudinal bars is studied by using the dimensional analysis and the incomplete self-similarity theory. Next, the theoretical analysis shows that a power equation can be used for establishing the stage-discharge equation. The coefficient and an exponent of the power equation depend on the slope angle and the void ratio. Finally, this new stage discharge is tested by using measurements obtained by laboratory runs conducted in this investigation.
Closure to “Experimental Study of the Stage-Discharge Relationship for an Upstream Inclined Grid with Longitudinal Bars” by C. Di Stefano and V. Ferro
2014
The discusser would like to thank the authors of the original paper for investigating the outflow process of an upstream inclined grid with longitudinal bars using the dimensional analysis and the incomplete self-similarity theory. The discusser, however, would like to add a few points. Using the theoretical analysis the authors of the original paper showed that a power equation can be used for establishing the stage-discharge equation of an upstream inclined grid with longitudinal bars. The authors of the original paper also showed that the coefficient and exponent of the power equation depend on the slope angle and the void ratio. They proposed a stage-discharge equation
Identifying the k Best Targets for an Advertisement Campaign via Online Social Networks
2020
We propose a novel approach for the recommendation of possible customers (users) to advertisers (e.g., brands) based on two main aspects: (i) the comparison between On-line Social Network profiles, and (ii) neighborhood analysis on the On-line Social Network. Profile matching between users and brands is considered based on bag-of-words representation of textual contents coming from the social media, and measures such as the Term Frequency-Inverse Document Frequency are used in order to characterize the importance of words in the comparison. The approach has been implemented relying on Big Data Technologies, allowing this way the efficient analysis of very large Online Social Networks. Resul…
Antidiabētiska līdzekļa metformīna neirorestoratīvo efektu izpēte eksperimentāli izveidotajā Alcheimera slimības modelī
2022
levads. Glikozes metabolisma traucējumi un kognitīvie traucējumi ir vienas no agrīnām sporādiskās Alcheimera slimibas (sAD) pazīmēm. Agrīna terapeitiskā iejaukšanās varētu apstādināt kognitīvos traucējumus pirms sAD progresēšanas. Metformīns, visplašāk zināms pretdiabeta līdzkelis, ir uzrādījis spēju uzlabot kognitīvās funkcijas un glikozes metabolismu otra tipa diabēta pacientos un diabēta modeļdzīvniekos. Intranazālais ievadīšanas veids ļauj samazinaāt preparāta devu un mazina blakusparadibu izpausmes. Pie tam, metformīns šķērso hematoencefālisko barjeru un ir spējīgs izplatīties smadzenēs pēc vienreizējās ievadīšanas. Intranazālas metformīna ievadīšanas efekti uz sociālo uzvedību iepriek…
Soluzioni tecnologiche e lotta al Covid-19: una riflessione critica
2023
Technological solutions and the fight against Covid-19. A critical reflection – Digital technologies have played a decisive role in the definition and implementation of measures to combat the Covid-19 pandemic, from the dissemination of information to the monitoring of behavior. Yet their use has not always achieved the desired effects. By reviewing the case of tracking apps, this contribution aims to take stock of the role of technologies and the private sector during the pandemic emergency and to reason about the causes of their failure.
Consolidated challenge to social demand for resilient platforms : Lessons from Uber's global expansion
2017
Many in the industry see the ride-sharing company Uber as the significant advancement through information and communication technology (ICT) particularly of the digital service platform and sharing economy. Uber has been exploring the new frontier of the ICT-driven disruptive business model (IDBM) and succeeded in its global expansion to over 479 cities in more than 75 countries worldwide in June of 2016. Such rapid expansion provides constructive insights regarding the significance of IDBM, not only in transportation but also in almost all other business fields. While at the same time Uber's legal battles in some cities around the world raise a serious question regarding the rationale of I…
Fuzzy Degree of Geographic Appropriateness for Social Impact Investing
2017
Impact investing is an investment practice that is characterized by the explicit intentionality of attaining a social impact and the requisite of report and measure this impact in a transparent way. The investment decision making process has two main stages. In the first stage, filters are applied regarding four critical issues: target geography, impact theme, asset class and target return category. In this phase, the set of possible investment alternatives are determined based on their appropriateness for impact investment in terms of those four essential aspects. In a second stage, efficient portfolios are obtained taking into account financial criteria (maximizing expected return, minimi…
Soft Computing Techniques for Portfolio Selection: Combining SRI with Mean-Variance Goals
2014
A fuzzy portfolio selection model is presented incorporating a socially responsible goal without discarding a priori financially good portfolios or weakening a priori the financial goals. Hence, the optimal portfolios it provides could be either efficient from the strictly financial point of view or non-efficient if leaving the efficient frontier substantially improves the degree of social responsibility. The model can be used to direct heuristic procedures in order to select a reduced number of various alternatives from which the investor can directly make a final decision.
