Speciālo izmeklēšanas darbību aktuālie problēmjautājumi
2016
Maģistra darbs sniedz padziļinātu ieskatu speciālo izmeklēšanas darbību kā kriminālprocesuāla institūta problēmjautājumos, kuru pamatā lielākoties ir tieši teorijā un praksē nostiprinājušos atziņu dažādība. Darbs sastāv no trim galvenajām nodaļām, kurās autore apzina un analizē speciālo izmeklēšanas darbību teorētiskos un praktiskos aspektus un no to atšķirīgās normatīvā regulējuma interpretācijas izrietošos tādus aktuālos problēmjautājumus kā saistība ar operatīvās darbības pasākumiem, ar šīm darbībām saistīto procesuālo dokumentu un darbību veicēju liecību nozīme pierādīšanā, iegūtās informācijas aizsardzība u.c. Darba rezultātā autore konstatē pretrunas tiesību normu piemērošanā un ieros…
Effects of Rule Changes on Game-Related Statistics in Men's Water Polo Matches
2017
The aim of this study was to investigate the effects of rule changes on game-related statistics in men's water polo matches. A total of 856 men's matches played in all Olympic Games and World Championship since 1936 was analysed. The game-related statistics considered were: total goals, winners' goals, losers' goals, goals per minute, goals difference, relationship difference goals and total goals, and relationship difference goals and winners' goals. The rule changes were grouped by structural (game and period) and functional changes (possession time, exclusion time, timing, minimum distance to take a direct shot). Differences between rule changes were determined using a one-way ANOVA. In …
Brand social representations: strategic perspectives for a fitness club
2009
International audience; The aim of this study was to identify an accurate tool to enable fitness club managers to discover those opinions or stereotypes which represent obstacles to joining their organisations. Starting with brand image, the analysis then considered social representations as relevant constructs for apprehending these opinions or prejudices. The use of a word association task and the model of basic cognitive schemes (Rouquette, 1990; 1994) provided access to the salient elements of the social representations of a particular sport brand and the way they are structured. The procedure combining these two stages represented a diagnostic tool for identifying the attractive and un…
Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans
2017
In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…

I poligoni stellati: origini storiche ed implicazioni didattiche
2019
The genesis of mathematical concepts in the evolutionary line of human thought in the long story and the genesis in individual optics possess evident analogies. Starting from this assumption, we describe an activity presented to 15-year-old students; the aim was to consolidate fundamental concepts of Euclidean geometry related to regular polygons. The experimentation has used a didactic approach based on the historical evolution of the formal definition of regular star polygon through the centuries. The activity and the results obtained in terms of internalization of the concepts in the students are showed.
Impact of supplier-specific investments in inter-organisational information systems on strategic electronic coordination: the moderation effect of bu…
2018
Abstract This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of …
