Sources of life satisfaction judgments in Latvia
2010
AbstractResearch indicates that life satisfaction judgments may be influenced by many different factors, but there is no clear evidence how these judgments are constructed. The purpose of this study was to examine sources of life satisfaction judgments in Latvia. Respondents (N=605) aged 18 - 70 completed self report measures of life satisfaction (SWLS), satisfaction with life domains, stressful life events, positive and negative affects (PANAS). Regression analysis shows that model including satisfaction with different life domains, positive and negative affects and number of stressful life events measures explains 53% of the variance in the overall life satisfaction. Immediately after com…
Shakedown of elastic—plastic solids with frictionless unilateral contact boundary conditions
1997
Abstract Elastic perfectly plastic solids (or structures) in frictionless unilateral contact with a rigid obstacle and subjected to quasi-statically variable loads within a given domain are considered. In the hypothesis that the structure undergoes small displacements and complies with a d -stability requisite herein introduced, a Melantype shakedown theorem is presented. This theorem is conceptually similar to the classical one; namely, it requires that the unilateral-contact elastic stress response to the loads and to some initial plastic strains be plastically admissible everywhere in the body and for all load conditions. A method for evaluating the shakedown load boundary is also discus…
RDF-Based Web Information Integration System: A Travel System Use Case
2018
Enterprises are continually faced with the challenge of integrating heterogeneous systems with incompatible interfaces, data structures (Source structured relational databases, semi-structured sources, XML, or unstructured documents: texts), access mode and technologies. When companies adopt SOA (Service Oriented Architecture), that provides an alternative to traditional design of applications by allowing a designer to assemble and compose existing services that implement the functions of a given application domain, they realize that there is a significant risk that Web services only do not solve the problem of compatibility in the data. Our paper gives a solution to these issues by setting…
Joint Audit: Issues and Challenges for Researchers and Policy-Makers
2013
International audience; The publication of the European Commission Green Paper, ‘Audit Policy: Lessons from the Crisis’ in October 2010, has stirred up a lively debate on the role of joint audits. This literature review identifies and evaluates, for the benefit of future research and regulators, existing evidence about joint audits. We find limited empirical support to suggest that joint audits lead to increased audit quality, but some empirical support to suggest that joint audits lead to additional costs. Overall, this paper indicates that joint audit should be seen as a mechanism that is embedded in a broader institutional context and not be considered in isolation from other factors tha…
IS evolution benefit assessment: Challenges with economic investment criteria
2007
Maintenance and system evolution activities have a significant role in the information system (IS) life cycle. It has been estimated that approximately 80% of the total IT expenses are allocated for maintenance activities [20]. According to Lehman’s first law, maintenance is necessary, because software needs to be continuously improved or it will get out of date and cannot respond to the requirements of its environment [19]. Despite the importance of IS evolution investments, there is a gap between the IT related costs and company profitability [27]. Brynjolfssen [10] described this as a productivity paradox: information technology utilization has increased since the 70’s but simultaneously…
Distopía, eutopía y crisis social en el cine mainstream (Los casos de Los juegos del hambre y Del revés)
2018
espanolEn el marco de un mundo globalizado, la aparente "desideologizacion" que acompana a los bienes culturales actuales, sirve a los propositos de reproduccion del sistema capitalista, entendido este dentro de su vertiente cultural actual como un sistema omnipresente y omniabarcante. En este sentido, los productos culturales del mainstream estadounidense, continuan constituyendo, aun a dia de hoy, uno de los principales pilares a traves de los cuales el sistema se representa a si mismo, proponiendo y defendiendo determinados modos de vida, en concreto, el American Way of Life. En el actual contexto, el mainstream cinematografico, a traves de productos como “Los Juegos del Hambre” (The Hun…
Reuse of electric vehicle batteries in buildings: An integrated load match analysis and life cycle assessment approach
2019
Abstract The increasing use of renewable energy technologies for electricity generation in buildings will require a growing number of battery energy storage systems (BESS) to enhance the reliability of electricity supply. The increasing number of retired electric vehicle (EV) batteries, expected from the automotive sector, can match this demand as EV batteries can be used as BESS, considering that they have about 80% of their original energy capacity. In this context, the study aims at examining the system, consisting of a BESS made by retired Li-ion EV batteries, a photovoltaic plant (20 kW) and the electricity grid, that provides the electricity required by an existing nearly net zero res…
Bērnības ģimenes vides un piesaistes stilu saistība ar pārmērīgu datorspēļu spēlēšanu pieaugušā vecumā
2022
Šī maģistra darba mērķis ir noskaidrot, kādai bērnības ģimenes videi (atvērtai, vienotai vai konfliktējošai) un piesaistes stilam (trauksmainam vai izvairīgam) ar vecākiem, ir saistība ar indivīda pārmērīgu tieksmi spēlēt spēles internetā pieaugušā vecumā? Pētījumā piedalījās 80 cilvēki, visi dalībnieki bija pieaugušie, kuri pēdējo 6 mēnešu laikā ir spēlējuši spēles internetā, datorā vai telefonā. No tiem bija 48 vīrieši un 31 sieviete, vecumā no 18 līdz 45 gadiem (vidējais dalībnieku vecums ir 25 gadi). Pētījuma dalībniekiem, atbildot uz piedāvātajiem jautājumiem, bija jāsniedz novērtējums par savu bērnības ģimenes vidi, piesaistes attiecībām ar vecākiem un tuvākajiem cilvēkiem, kā arī jān…
Pheromone-induced odor learning modifies Fos expression in the newborn rabbit brain.
2013
Research report; International audience; Associative learning contributes crucially to adjust the behavior of neonates to the permanently changing environment. In the European rabbit, the mammary pheromone (MP) excreted in milk triggers sucking behavior in newborns, and additionally promotes very rapid learning of initially neutral odor cues. Such stimuli become then as active as the MP itself to elicit the orocephalic motor responses involved in suckling. In this context, the rabbit is an interesting model to address the question of brain circuits early engaged by learning and memory. Here, we evaluated the brain activation (olfactory bulb and central regions) induced in 4-day-old pups by …
La distribution des tuiles estampillées de la VIIIe légion Augusta autour de Mirebeau-sur-Bèze (Côte-d'Or, France)
2011
The 8th Augustan Legion was installed at Mirebeau-sur-Bèze (Côte-d'Or) after 70 AD following the troubles that arose with the Lingons. It remained there until the time of Domitian, a period of roughly twenty years, during which time the soldiers produced tiles stamped with the name of the legion. Analysis of the dispersion of the tiles in the region around Mirebeau shows that they followed the communication routes. Consideration of the contexts in which these tiles were used, their number on each site and the resources necessary to manufacture them reveals that the 8th Legion may have played a significant role in the diffusion and adoption of tiled roofs, a construction technique that was t…
