Referento grupu ietekme uz Latvijas patērētāju uzvedību sociālo mediju viedokļu līderu (influenceru) kontekstā.
2019
Digitālo tehnoloģiju un sociālo tīklu ieviešanas dēļ informācijas apmaiņa sabiedrībā kļuvusi daudz intensīvāka, cilvēkiem ir plašākas iespējas izteikt savu viedokli un ietekmēt citu cilvēku uzvedību, kā rezultātā referento grupu, it īpaši sociālo mediju viedokļu līderu (influenceru), ietekme uz patērētāju palielinās. Līdz ar to Bakalaura darba mērķis ir, pamatojoties uz references grupu ietekmes teorētisko aspektu salīdzinošu izpēti, analizēt un novērtēt referento grupu, it īpaši sociālo tīklu viedokļu līderu (influenceru), ietekmes tendences uz Latvijas Y un Z paaudžu patērētāju uzvedību, piedāvājot Latvijas uzņēmumiem rekomendācijas mārketinga darbības un konkurētspējas uzlabošanai.

Valeurs de référence du valproate de sodium (CAS n°1069-66-5). Valeurs toxicologiques de référence par voie orale et inhalation, valeurs limites d’ex…
2021
Le site de Sanofi situé à Mourenx, dans le bassin industriel de Lacq (64), produit un médicament antiépileptique, la Dépakine®, dont le principe actif est le valproate de sodium (VPS). Ce site est une installation classée pour la protection de l’environnement (ICPE) soumise à autorisation au titre de l’article L.511-1 et suivants du Code de l’environnement. Les rejets dans l’environnement d’une telle installation sont encadrés par des limites établies sur la base d’une évaluation quantitative des risques sanitaires (EQRS). En 2017, Sanofi Chimie a réalisé une évaluation de l’impact sur la santé et l’environnement des rejets atmosphériques de valproate, en utilisant des valeurs toxicologique…
Reward-based crowdfunding campaigns: Informational value and access to venture capital
2018
We consider an entrepreneur who designs a reward-based crowdfunding campaign when the campaign provides a signal about the future demand for the product and subsequent venture capital is needed. We find that both the informativeness of the campaign and considerations related to gaining access to venture capital funding affect the entrepreneur’s choice of campaign instruments, as well as her decision of whether to run a campaign. In particular, entrepreneurs should launch the campaign either when it is highly informative or when it is not informative at all. For relatively low levels of informativeness, but not so low that the venture capitalist (VC) completely ignores the campaign outcome …
Do Children Cooperate Conditionally?:Adapting the Strategy Method for First-Graders
2020
We develop a public goods game (PGG) to measure cooperation and conditional cooperation in young children. Our design addresses several obstacles in adapting simultaneous and sequential PGGs to children who are not yet able to read or write, do not possess advanced abilities to calculate payoffs, and only have a very limited attention span. It features the combination of haptic offline explanation, fully standardized audiovisual instructions, computerized choices based on touchscreens, and a suitable incentive scheme. Applying our experimental protocol to 129 German first-graders, we find that already 6-year-olds cooperate conditionally and that the relative frequency of different cooperati…
The political, legal and moral scope of the universal declaration of human rights: pending issues
2018
With the adoption of the Universal Declaration of Human Rights, a new era began in the recognition and guarantee of human rights in the international area. However, since the moment of its approval, this text has received negative evaluations designed to relegate it to the background. The responses to these criticisms allow us to review their political and legal scope, and put it in value as a reference model in the field of human rights, delving into the pending issues to strengthen it. This is intended, on the seventieth anniversary of the Declaration, to insist that this remains an essential bridge to clarify standards that can serve as a basis for discussion between different cultures a…
Is money where the fun ends? Material interests and individuals’ preference for direct democracy
2020
Abstract Are people’s attitudes towards referendums as a decision-making procedure predominantly driven by their material self-interest, or do individuals also value direct democracy as such, regardless of the material payoffs associated with anticipated policy outcomes? To answer this question, we use a survey data set that offers information on respondents’ support for referendums as a procedure to decide on tax policy, their income levels, socio-economic characteristics, and, most importantly, their expectation about the majority’s support for higher taxes. We find that the support of low-income individuals for referendums increases substantially if they expect a clear population majorit…
Anti‐laminin auto antibodies in ANCA‐associated vasculitis
2000
Background. Endothelial cell damage occurs during vasculitic processes in vivo. With the alteration of the endothelium, exposure to basement membrane components may occur with induction of humoral immunity. Methods. In the present study, we evaluated the prevalence of antibodies against the basement membrane antigen laminin (LMN) in patients with ANCA-associated systemic vasculitis (AASV), pathologic controls (systemic lupus erythematosus, mixed cryoglobulinaemia, Henoch Schonlein purpura, primary glomerulonephritis) and normal individuals. Results. By ELISA, 21.6% of AASV (16/74) and 10% of pathologic controls (3/30), but only one of the normal controls (2.8%) had these antibodies (P = 0.0…
Retrieval of vegetation height in rice fields using polarimetric SAR interferometry with TanDEM-X data
2017
This work presents for the first time a demonstration with satellite data of polarimetric SAR interferometry (PolInSAR) applied to the retrieval of vegetation height in rice fields. Three series of dual-pol interferometric SAR data acquired with large baselines (2–3 km) by the TanDEM-X system during its science phase (April–September 2015) are exploited. A novel inversion algorithm especially suited for rice fields cultivated in flooded soil is proposed and evaluated. The validation is carried out over three test sites located in geographically different areas: Sevilla (SW Spain), Valencia (E Spain), and Ipsala (W Turkey), in which different rice types are present. Results are obtained duri…
Non-fragile sliding mode control for flexible air-breathing hypersonic vehicles
2012
The non-fragile sliding mode tracking control design problem for a flexible air-breathing hypersonic vehicles (FAHVs) is investigated in this paper. A linearized model is constructed with respect to a trim point for the nonlinear, dynamically coupled simulation model of the FAHVs with external disturbance, then a reference model is designed and a tracking error model is proposed. An integral sliding surface is designed, and then the non-fragile H ∞ controller design problem for the sliding mode dynamics is discussed. sufficient condition is derived for the existence of such a controller in the presence of unmatched disturbance. A SMC law is derived to guarantee the reachability of the speci…
