CHANGING SCHOOL AFTER THE GLOBAL RECESSION : THE CASE OF LATVIA
2015
Latvia demonstrates common trends with the majority of the countries affected by the recession, as well as some peculiarities in overcoming the impact of the global economic and financial recession on education mainly due to an unbelievable austerity. Education in this country has suffered greatly, and its damage is adequate to the 67% of the budget cuts between 2008 and 2011 (IZM, 2011). The article deals with the school improvement after the recession, recent implementation of innovations to cover the damages and catch up with the ideas of the Next Generation learning, to supply schools with the appropriate curricula and meeting the learners needs for their individual development and abil…
Agricultural Insurances and Food Security. The New Climate Change Challenges
2015
Abstract Food security is one of the highest problems that the governments have to face in the third millennium. The complexity of this problem justifies the performance of researches, in view of finding viable solutions, not only in agriculture, but in other branches of activity too. Among them, the field of insurances is to be noted by its struggles to adapt to the new challenges. This paper tries to clarify the way in which insurances may become a key factor for the food security and addresses the following issues: food security factors; factors impacting on the development of agricultural insurances, risks connected to the agricultural activities and the way in which the insurance prote…
Sectoral policies cause incoherence in forest management and ecosystem service provisioning
2022
Various national policies guide forest use, but often with competing policy objectives leading to divergent management paradigms. Incoherent policies may negatively impact the sustainable provision of forest ecosystem services (FES), and forest multifunctionality. There is uncertainty among policymakers about the impacts of policies on the real world. We translated the policy documents of Finland into scenarios including the quantitative demands for FES, representing: the national forest strategy (NFS), the biodiversity strategy (BDS), and the bioeconomy strategy (BES). We simulated a Finland-wide systematic sample of forest stands with alternative management regimes and climate change. Fin…
Key Electoral Institutions and Rules Influencing Proportionality and Partisan Bias in Spanish Politics
2021
The current paper focuses on the Spanish electoral rules governing political competition for the central “Congreso de los Diputados”. It is well-documented that the system as a whole has traditionally favoured one or the other of the two main political parties (PP and PSOE) at the expense of proportionality and the remaining political parties. This paper focuses on some key Spanish electoral rules and investigates how much the observed biases could be altered by introducing some alternative rules taken from the Swedish electoral system, ceteris paribus. Measures of disproportionality are made through the Loosemore–Hanby index and the Gallagher index. The electoral raw data used for our esti…
AGILITY AND THE ROLE OF PROJECT — INTERNAL CONTROL SYSTEMS FOR INNOVATION PROJECT PERFORMANCE
2019
As a reaction to the rapidly changing environment, organisations increasingly use agile project management (APM) methods to develop innovation. The associated process changes necessitate the adaption of organisational structures and control systems. This study draws on Simon’s Levers-of-Control framework (LOC) to explore the impact of different control levers on innovation project performance. Based on a survey of 316 project managers and product owners, the results suggest that the use of interactive project control systems and project-internal belief systems has a positive impact on the innovation outcome, regardless of the degree of agility of the project. Furthermore, we reveal that a s…

Comparing soil inventory with modelling: Carbon balance in central European forest soils varies among forest types
2018
Abstract Forest soils represent a large carbon pool and already small changes in this pool may have an important effect on the global carbon cycle. To predict the future development of the soil organic carbon (SOC) pool, well-validated models are needed. We applied the litter and soil carbon model Yasso15 to 1838 plots of the German national forest soil inventory (NFSI) for the period between 1985 and 2014 to enables a direct comparison to the NFSI measurements. In addition, to provide data for the German Greenhouse Gas Inventory, we simulated the development of SOC with Yasso15 applying a climate projection based on the RCP8.5 scenario. The initial model-calculated SOC stocks were adjusted…
Impact of historical mining assessed in soils by kinetic extraction and lead isotopic ratios.
2014
12 pages; International audience; The aim of this study is to estimate the long-term behaviour of trace metals, in two soils differently impacted by past mining. Topsoils from two 1 km(2) zones in the forested Morvan massif (France) were sampled to assess the spatial distribution of Cd, Cu, Pb and Zn. The first zone had been contaminated by historical mining. As expected, it exhibits higher trace-metal levels and greater spatial heterogeneity than the second non-contaminated zone, supposed to represent the local background. One soil profile from each zone was investigated in detail to estimate metal behaviour, and hence, bioavailability. Kinetic extractions were performed using EDTA on thre…
A laboratory study of the mineralization and binding of 14C-labeled herbicide rimsulfuron in a rendzina soil
1999
Abstract The fate of pyrimidine-2- 14 C-rimsulfuron in a rendzina soil was investigated using a laboratory microcosm approach. Measurement of CO 2 evolution suggested that rimsulfuron applied at 5 times the recommended dose did not affect soil respiration. Under abiotic conditions, no mineralization of 14 C-rimsulfuron into 14 C-CO 2 occured and under biotic ones it was very low reaching 0.75 % of the applied 14 C-rimsulfuron after 246 days of incubation. The analysis of data showed that a three-half order model provided the best fit for the mineralization curve. Extractable 14 C-residues decreased over time to 70 – 80% of the applied 14 C-rimsulfuron at the end of the incubation. After 246…
Characterization of an isoproturon mineralizing bacterial culture enriched from a French agricultural soil.
2009
The phenylurea herbicide isoproturon, 3-(4-isopropylphenyl)-1,1-dimethylurea (IPU), was found to be rapidly mineralized by a bacterial culture isolated from an agricultural soil regularly exposed to IPU. Molecular analysis of the bacterial culture by DNA fingerprinting, cloning and sequencing of the 16S rRNA genes revealed that it consisted of six different members among whom the dominant was related to Sphingomonas sp. Six bacterial strains belonging to genera Ancylobacter, Pseudomonas, Stenotrophomonas, Methylobacterium, Variovorax and Agrobacterium were isolated from the IPU-degrading culture. None of these were able to degrade IPU in pure culture and only the intact culture sustained th…
