Contingent reward leader behaviour: Where does it come from?
2010
As many academics have pointed out, while researchers have learned a great deal about the effects of contingent reward (CR) leader behaviour, relatively little is known about its genesis. CR transactional leadership is traditionally viewed as an independent variable which exerts influence downstream. However, if we are to understand how to influence, improve or modify these downstream effects, we need to shift our focus upstream towards the study of transactional leadership as a dependent variable. In line with this reasoning, we put forward the hypothesis that a contextual variable (organizational learning capability) and a subordinate's characteristic (employability) are antecedents of CR…
Stratégie du e-commerçant, accessibilité du produit et logistique urbaine
2013
Several factors impact urban logistics, among them, the recent evolution of e-commerce, by the new flows that it introduces in the city. It seemed interesting to us to understand urban logistics in this way, taking an original point of view, that of the upstream part of the logistics chain, namely the e-commerce strategy. We were thus able to highlight strategic and structural choices having consequences on product accessibility and urban logistics.
The effect of cooperative infrastructure fees on high-speed rail and airline competition
2021
Abstract This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution off…
Interbasin Water Transfers in Spain: Interregional Conflicts and Governance Responses
2014
Semiarid and drought-prone Spain has managed to meet ever-increasing water demands for more than 50 years through the construction of publicly funded hydraulic infrastructure. Interbasin water transfers are the most expensive and complex supply-side tool used. They are also the most controversial, often associated with such unintended consequences as deteriorating freshwater ecosystems, disappearing recreational opportunities provided by aquatic ecosystems, and the loss of development opportunities for downstream communities. This situation has become increasingly unstable over the past decade due to the scarcity of new supply augmentation alternatives, political changes involving European …
Monthly Hydrological Indicators to Assess Possible Alterations on Rivers’ Flow Regime
2018
Assessing potential deviations of the fundamental river basins’ hydrological processes and streamflow characteristics from the “natural trajectory” represents a high-priority objective to understand the biological impact of altered flow regime on river ecosystems. Existing approaches are mainly based on the analysis of daily-based indicators of hydrologic alteration, which requires wide database, including “pre-impact” and “post-impact” daily flow data frequently unavailable. The hydrological modeling is commonly used to face data missing problems or reconstruct natural conditions, even if models, especially at the daily scales, are often complex and computationally intensive. The use of si…
Trans-boundary land cover changes and its influences on water crisis: Case study of the Aras River
2020
Abstract In a watershed, disturbing land covers (LCs) are one of the most important factors in the balance and flow rate of water. This study aimed to monitor and model LC changes in the upstream of the Aras River Basin in Turkey over 1984, 2002, 2010 and 2016. The main ground to conduct such an analysis was to mitigate severe economic, social and ecological consequences driven by agricultural activities and dam construction along with probable climate change, which would decrease the water flow from the Aras River to Caspian Sea. The study approach consisted of four main steps: 1) producing LC maps using Landsat satellite images, 2) performing the change analysis, 3) identifying the change…
Interaction model: Reflexiv leadership in the face of tensions in the school’s practical day to day handling
2023
Author's accepted manuscript Rektorer opplever utfordringer i det å arbeide som faglig, pedagogisk og administrativt ansvarlig på skolen. Faglig, pedagogisk og administrativt hensyn kan fort komme i konflikt med hverandre og skape spenninger i rektors arbeid. Denne artikkelen undersøker rektorenes opplevelse av å være leder på skolen, og hvordan de kan håndtere disse spenningene. For å komme så nære rektorene som mulig er det benyttet reflektive livsverdensintervjuer. Resultater i denne artikkelen støtter tidligere resultater i nordisk forskning om at administrative oppgaver tar fokus bort fra utviklingsoppgaver og at det er spenninger mellom ulike oppgaver i rektors arbeid. For å illustrer…
Design and Analysis of Electric Powertrains for Offshore Drilling Applications
2016
Doktorgradsavhandling ved Institutt for ingeniørvitenskap, Universitetet i Agder, 2016 The global energy market is challenged with an ever increasing need for resources to meet the growing demands for electric power, transportation fuels, etc. Although we witness the expansion of the renewable energy industry, it is still the fossil fuels, with oil and gas dominating the scene of global energy supply sector, that provide majority of worldwide power generation.However, many of the easily accessible hydrocarbon reserves are depleted which requires from the producers of drilling equipment to focus on cost-effective operations and technology to compete in a challenging market. Particularly high…
Iekšējā kontroles sistēma un tās novērtējums ITuzņēmumā.
2020
Uzņēmuma efektīva darbība nav iespējama bez stabilas iekšējās kontroles sistēmas, kas nosaka finanšu un saimnieciskās darbības likumību un efektivitāti. Jo lielāks ir uzņēmums, jo augstākas ir prasības kontroles sistēmai. Bakalaura darba mērķis ir, pamatojoties uz literatūras izpētī un Accenture Latvijas filiāles iekšējās kontroles sistēmas analīzi, izstrādāt priekšlikumus tās uzlabošanai. Pētījumā tika analizēta Accenture Latvijas filiāles iekšējās kontroles sistēma. Autore secina, ka uzņēmuma iekšējās kontroles sistēmas elementiem ir trūkumi. Darba nobeigumā autore sniedz ieteikumus iekšējās kontroles sistēmas uzlabošanai un nepilnību novēršanai. Darba apjoms ir 78 lpp, 14 attēli, 4 tabul…
Iekšējās kontroles sistēmas trūkuma radītās problēmas valsts tiešās pārvaldes iestādēs
2015
Maģistra darba aktualitāti pamato fakts, ka 2013.gadā Finanšu ministrijas sagatavotajā informatīvajā ziņojumā valdībai tika secināts - 20% gadījumu par valsts pārvaldē īstenotajām funkcijām un uzdevumiem izteiktais viedoklis nav bijis pietiekami pamatots, tostarp, konstatēti būtiski trūkumi iekšējā kontroles sistēmās. Arī 2011.gadā un 2012.gadā valsts tiešās pārvaldes iestādēs tika konstatētas līdzīgas problēmas. Maģistra darba mērķis ir izpētīt valsts tiešās pārvaldes iestāžu iekšējās kontroles sistēmas, to regulējumu, iekšējās kontroles sistēmas ietekmi uz valsts tiešās pārvaldes iestāžu profesionālo darbību, kā arī izstrādāt priekšlikumus valsts tiešās pārvaldes iestāžu iekšējās kontrole…
