Transport planning as suggested in John Claudius Loudon’s 1829 plan for London
2017
ABSTRACTWe consider Scottish landscape gardener J.C. Loudon’s already well-documented 1829 plan for a system of successive green belts around London. Our perspective will be that of transport planning, given his recommendations on street layout and public transport provision. Our contention is that Loudon’s design for the Metropolis would have been theoretically inoperative if it had not been for its transport network. Beside other forward-thinking aspects already demonstrated by researchers, Loudon’s plan is remarkable for setting out a design for an integrated Metropolis based on road planning and the then barely nascent technology of railways.

The ABC of society: Perceived similarity in agency/socioeconomic success and conservative-progressive beliefs increases intergroup cooperation
2020
Abstract The dimensions that explain which societal groups cooperate more with which other groups remain unclear. We predicted that perceived similarity in agency/socioeconomic success and conservative-progressive beliefs increases cooperation across groups. Self-identified members (N = 583) of 30 society-representative U.S. groups (gays, Muslims, Blacks, upper class, women, Democrats, conservatives etc.) played an incentivized one-time continuous prisoner's dilemma game with one self-identified member of each of these groups. Players knew nothing of each other except one group membership. Consistent with the ABC (agency-beliefs-communion) model of spontaneous stereotypes, perceived self-gr…
Design, validation, and testing of an observational tool for technical and tactical analysis in the taekwondo competition at the 2016 Olympic games.
2020
Abstract Observational methodology uses validated observational tools to collect information in sports with multiple variables that interact in the sporting context. Given the importance of data quality for observational tools, the purpose of this study was to design, validate, and test the reliability of a mixed observational instrument combining field formats and category systems for analyzing technical and tactical actions in an Olympic taekwondo (TKD) tournament. The instrument collects information of six criteria and 25 categories of the tactical and technical actions, kicking zone, laterality, kicking leg, guard, and score. A total of 2 374 actions were analyzed from 10 bouts involvin…
Zur therapie der �sophagusvarizenblutung in der Bundesrepublik Deutschland (West) ? Ergebnisse einer Urnfrage
1991
An 1076 chirurgischen und internistischen Abteilung in der BRD (West) wurde eine Umfrage zur Behandlung der Osophagusvarizenblutung durchgefuhrt. Es uberwiegt die Akutsklerosierung bzw. die Ballonsondenbehandlung mit nachfolgender Sklerosierung bei der aktiven Blutung. Die abdominelle Sperroperation wird bei der konservativ nicht stillbaren Blutung noch vor dem portokavalen Notshunt bevorzugt. Betablocker werden vor allem in internistischen Abteilungen zur Rezidivprophylaxe eingesetzt. Erst nach mehrfacher Rezidivblutung trotz Sklerosierung sehen etwa die Halfte der Abteilungen eine Indikation zum elektiven Shunt. Der distale splenorenale Shunt nach Warren and die portokavale Anastomose dom…
Optimal selection of touristic packages based on user preferences during sports mega-events
2022
Sport mega-events, such as the Soccer World Cup or Olympic Games, attract many visitors from all over the world. Most of these visitors are also interested in, besides attending the sports events, visiting the host nation and the neighboring countries. In this paper, we focus on the upcoming FIFA World Cup Qatar 2022. As per the schedule of the tournament, a national team can play 7 matches at most. Therefore, a supporter will have six short breaks (of three to five days) between consecutive matches in addition to two longer ones, immediately before and after the tournament, during which they can plan some touris- tic trips. We study the problem faced by a touristic trip provider who wants …
Network embeddedness and new product development in the biopharmaceutical industry: The moderating role of open innovation flow
2015
This paper explores the role of centrality and structural holes positions on the likelihood to develop new products and the moderating role of the open innovation flow, a measure of the net knowledge flow crossing the firm’s boundaries, on the aforementioned relation. We argue that network positions provide the information content to the firm, whilst open innovation flow describes how the firm uses such content, thus the combination of these two concepts has a significant impact on new product development. We test the theoretical framework on a large sample of 544 public companies and data from 1758 agreements among 1890 bio-pharmaceutical firms through the period 2006–2010. Our results sho…
Māsas un pacienta sadarbības hroniskas obstraktīvas plaušu slimības gadījumā
2021
Bakalaura darba tēma ir “Māsas un pacienta sadarbības hroniski obstraktīvas plaušu slimības gadījumā”. Bakalaura darba aktualitāti nosaka, sabiedrības un īpaši pacientu ar jau esošo HOPS, nepietiekošās zināšanas par HOPS, kā rezultātā slimība netiek laicīgi diagnosticēta. Darba autore pēta un analizē, HOPS slimības ietekmi uz pacienta emocionālo un fizisko veselību, māsas sadarbību ar HOPS pacientiem, profilaksi un ārstēšanu, lai, vajadzības gadījumā, māsa varētu sniegt informatīvu atbalstu pacientiem izglītošanas nolūkā. Darba mērķis ir noskaidrot māsas un pacienta sadarbību HOPS gadījumā. Pētniecības jautājums: kāda ir māsas un pacienta sadarbība HOPS gadījumā? Izmantotā pētīju metode: kv…
Beyond Foreign Policy? EU Sanctions at the Intersection of Development, Trade, and CFSP
2022
In the wake of unsettling conflicts and democratic backsliding, states and organisations increasingly respond with sanctions. The European Union (EU) is one of them: Brussels makes use of the entire toolbox in its foreign policy, and its sanctions appear in different forms—diplomatic measures, travel bans, financial bans, or various forms of economic restrictions. Yet, there is little debate between different strands in the literature on EU sanctions, in particular concerning measures under the Common Foreign and Security Policy and those pertaining to the development and trade policy fields. Our thematic issue addresses this research gap by assembling a collection of articles investigating…
On approximate system dynamic
1996
In this paper concepts and techniques from system theory are used to obtain state-space (Markovian ) models of dynamic economic processes instead of the usual VARMA models. In this respect the concept of state is reviewed as are Hankel norm approximations,and balanced realizations for stochastic models. We clarify some aspects of the balancing method for state space modelling of observed time series. This method may fail to satisfy the so-called positive real condition for stochastic processes. We us a state variance factorization algorithm which does not require us to solve the algebraic Riccati equation. We relate the Aoki-Havenner method to the Arun - Kung method.
