Need for speed? Exploring the relative importance of patents and utility models among German firms
2017
Despite the wide use of two-tiered patent systems (patents and utility models (UMs)), there is little empirical evidence about how often UMs are actually used, what kind of firms use them to protect their intellectual property, and how firms rank them relative to patents. We offer such an analysis using data from Germany. We find that larger firms are more likely to use both protection methods. Moreover, a short life cycle of products and services is associated with an increased likelihood to use UMs. The features and functioning of the German UM system are of broader interest because it has been a benchmark for several second tier patent protection systems around the world. peerReviewed
Ģimenes modelis Augusta Saulieša īsprozā: „Izmeklēti raksti” (1922)
2015
Maģistra darba “Ģimenes modelis Augusta Saulieša īsprozā: “Izmeklēti raksti” (1922)” mērķis ir izpētīt ģimenes modeli, kāds attēlots rakstnieka Augusta Saulieša (1869-1933) prozā un noskairdot, kā tas atbilst 19. gadsimta beigu un 20. gadsimta sākuma latviešu ģimenes modelim. Darbā sniegts ieskats Saulieša biogrāfijā, rastas atbildes uz jautājumiem, kāda loma rakstnieka prozā attēlotajā ģimenē ir tēvam, mātei un bērniem. Apskatīts jautājums par attiecībām saimē, kā arī par urbanizācijas un izglītības iespēju ietekmi uz ģimenes modeļa maiņu. Salīdzinot Saulieša darbus ar viņa laikabiedru (Jāņa Poruka un Rūdolfa Blaumaņa), kā arī ar neseno priekšgājēju (Brāļu Kaudzīšu un Apsīšu Jēkaba) darbie…
The BIM (Building Information Modeling)-Based Approach for Road Pavement Maintenance
2019
The recent developments of road pavement survey technologies guarantee acquisition of detailed data regarding the main functional and structural indicators, at a very high frequency and levels of accuracy and precision unconceivable few years ago. The relevant information, regarding surface distresses too, is thus available in economical, high-speed and high-resolution forms, with limited disturbance on traffic and road agencies issues. However, the availability of such a mass of data poses interesting questions concerning the most efficient processing and analysis methods, for optimizing maintenance operation planning. Unfortunately, the PMS adoption is not very common and widespread, as t…
Iekšējās kontroles sistēmas novērtējums Raunas novada pašvaldības iestādēs
2018
Iekšējās kontroles sistēmai ir būtiska nozīme pašvaldības iestāžu darbības procesā, lai nodrošinātu šo iestāžu funkciju izpildi un mērķu sasniegšanu. Bakalaura darba mērķis ir, pamatojoties Raunas novada pašvaldības iestāžu dokumentu apritē un darbības aspektos, identificēt iekšējās kontroles sistēmas sastāvdaļas, novērtēt tās efektivitāti un sniegt priekšlikumus tās uzlabošanai. Mērķa sasniegšanai tiks analizētas galvenās normatīvās prasības, kas piemērojamas pašvaldības iekšējās kontroles sistēmai, raksturota pašvaldības darbības būtība, lai identificētu iekšējās kontroles sastāvdaļas un trūkumus pašvaldības iestādēs, kā arī veikta anketēšana sistēmas novērtēšanai.
Modeling the probability distribution of peak discharge for infiltrating hillslopes
2017
Hillslope response plays a fundamental role in the prediction of peak discharge at the basin outlet. The peak discharge for the critical duration of rainfall and its probability distribution are needed for designing urban infrastructure facilities. This study derives the probability distribution, denoted as GABS model, by coupling three models: (1) the Green-Ampt model for computing infiltration, (2) the kinematic wave model for computing discharge hydrograph from the hillslope, and (3) the intensity-duration-frequency (IDF) model for computing design rainfall intensity. The Hortonian mechanism for runoff generation is employed for computing the surface runoff hydrograph. Since the antecede…
Runoff coefficients to predict peak discharge at hillslope scale: A small contribution to theoretical hydrology
2018
The science of hydrology holds a central role in the field of environmental Earth science, being intimately connected to meteorology, climatology, hydrogeology and ecology. In particular, the knowledge of hillslope hydrology is fundamental for understanding the flood phenomenon, for predicting the peak discharge and its probability distribution, which is necessary in many practical applications (design of hydraulic structures, urban, extra-urban planning, etc.). Using different approaches, there have been a multitude of studies on the hydrologic response at hillslope scale. One approach for deriving the hillslope response utilizes, in a distributed form, the differential equations of unstea…
Iterative Learning Applied to Hydraulic Pressure Control
2018
This paper addresses a performance limiting phenomenon that may occur in the pressure control of hydraulic actuators subjected to external velocity disturbances. It is demonstrated that under certain conditions a severe peaking of the control error may be observed that significantly degrades the performance of the system due to the presence of nonlinearities. The phenomenon is investigated numerically and experimentally using a system that requires pressure control of two hydraulic cylinders. It is demonstrated that the common solution of feed forwarding the velocity disturbance is not effective in reducing the peaking that occurs as a result of this phenomenon. To improve the system perfor…
Reconceptualising the Role of Talk in CLIL
2011
This theoretical paper offers a reconceptualisation of talk in CLIL based on sociocultural and dialogic theories of education. Building on these educational theories and the experiences of an on-going CLIL project, this paper presents a pedagogical model for the navigation of the ‘talkscape’ of the CLIL classroom. This model comprises a total of seven talk-types: organisational, social, critical, expert, exploratory, meta and pedagogic. In addition to these talk-types, the paper introduces the notion of a ‘transitional dynamic’. This notion aims to capture the transition from first language to foreign language use in CLIL both within the context of individual courses and across a broader CL…
A Longitudinal Study of the Effects of Service-Learning on Physical Education Teacher Education Students
2022
Research examining Service-Learning (SL) in Physical Education Teacher Education (PETE) is ample. However, long-term investigations are still scarce and literature demands the application of this type of design to uncover the effects of SL on the long run. This study followed a longitudinal quantitative approach; thus, the participants completed the Civic Attitudes and Skills Questionnaire (CASQ) in three occasions (pretest-postest1-postest2). Results show that there exist significant differences between mean values of the global outcomes of the CASQ; concretely, there was an improvement in the first interval followed by a decrease in the second period. Regarding the different dimensions of…
Vadīšanas modeļu un izglītības kvalitātes saistība Rīgas pašvaldības līdzfinansētajās privātajās vispārējās izglītības iestādēs Rīgas pilsētā
