Environmental conflicts of interest are important to account for when environmental policies are designed. This paper explores the quantitative connection between urban waste water treatment, coastal eutrophication, and fish biomass in the mesotrophic Gulf of Riga (northern Europe). The probable effect on the water quality from one clearly defined abatement measure, improved urban sewage treatment has been studied. Furthermore, the implementation cost and the likely effect on total fish biomass have also been assessed. Computer simulations using the previously published model CoastMab suggested that good water quality according to the EU Marine Strategy Framework Directive could be achieved if urban sewage treatment would be upgraded to Nordic and German standards, and not only around the Gulf of Riga but in the whole Baltic Sea drainage basin. The Secchi depth would double according to these simulations while total phosphorus and summer chlorophyll concentrations would decrease by 54% and 53%, respectively. The total fish biomass should be expected to decrease by about 42% if "good" water quality (as defined in European Union directives) should be achieved. However, changes in total fish biomass could also be offset by changes in other important determinants such as climate related variables or fishing pressure. The study estimated that it could take about 20-40 years after abatement action for the trophic state in the Gulf to stabilise again. Upgrading urban sewage treatment to this extent would cost 468-1,118 million euros per year. Treatment could have substantial positive effects on the water quality of the Gulf but could also have adverse side effects on the total fish biomass.

Human-elephant conflicts (HEC) in Asian elephant (Elephas maximus) range countries have been increasing during the past half-century and are a major conservation issue for governments. Research suggests studying the spatio-temporal behavioural patterns of E. maximus could indicate behavioural preferences and help mitigate such conflicts. These behavioural preferences could be influenced by factors such as seasonal and lunar cycles, and habitat type. This study aims to determine at what degree these influencing factors are driving E. maximus behaviour and HEC. Considering previous studies on seasonal and lunar cycles and habitat utilisation affecting E. maximus' behaviour and HEC it asks; How do these factors influence E. maximus behaviour and HEC events? Considering these factors, are there any correlations between HEC events and behaviour observed within an adjacent protected forest complex? HEC event data was obtained from the Wang Mee district; a community adjacent to a protected area, the Dong Phayayen – Khao Yai – forest complex in Thailand. This community has undergone increasing HEC in recent years. The data was analysed to identify the effects of the aforementioned factors on HEC frequency. Furthermore, camera trap data within the forest complex are also utilised to analyse the effects of these factors on behaviour, such as changes in the observations of E. maximus' mean distance to forest borders and habitat utilisation measured with relative abundance index (RAI). Analysis of data indicates a significant correlation between lunar and seasonal cycles and HEC events. HEC events were greater during hot and monsoon compared with the cold season. The RAI of E. maximus observations at forest borders were also significantly higher during hot season when compared to RAI at greater distances. First and last quarter moon phases indicated a significant increase in HEC in general. Seasonal and lunar cycles also determined the selection of mixed deciduous forest habitats, indicating a general increase in utilisation during the cold season. Utilisation during the cold season also varied greatly depending on the lunar cycle – increasing during the first quarter and lowest during full moon phases, indicating high variability. The results indicate that studying habitat selection preferences and seasonal and lunar cycles are important factors for park and HEC managers when mitigating conflicts. By understanding E. maximus' behaviour and habitat needs managers can better plan for effective management and HEC mitigation.

A special regulatory regime applies to products of recombinant nucleic acid modifications. A ruling from the European Court of Justice has interpreted this regulatory regime in a way that it also applies to emerging mutagenesis techniques. Elsewhere regulatory progress is also ongoing. In 2015, Argentina launched a regulatory framework, followed by Chile in 2017 and recently Brazil and Colombia. In March 2018, the USDA announced that it will not regulate genome-edited plants differently if they could have also been developed through traditional breeding. Canada has an altogether different approach with their Plants with Novel Traits regulations. Australia is currently reviewing its Gene Technology Act. This article illustrates the deviation of the European Union's (EU's) approach from the one of most of the other countries studied here. Whereas the EU does not implement a case-by-case approach, this approach is taken by several other jurisdictions. Also, the EU court ruling adheres to a process-based approach while most other countries have a stronger emphasis on the regulation of the resulting product. It is concluded that, unless a functioning identity preservation system for products of directed mutagenesis can be established, the deviation results in a risk of asynchronous approvals and disruptions in international trade.

This report is based on the results obtained from two questionnaire studies carried out during 1999 and 2007. The aim of the studies is to increase our knowledge about the attitudes and approach of the police to traffic safety work and how these attitudes have changed with time. In the first study 729 randomly chosen police officers completed the questionnaire and in the second 1,022. The results show that the basic attitude among the police towards traffic surveillance has become more positive. The attitudes towards the directives from the governing bodies and their ability to participate in decision making have improved slightly from the first measurement to the second measurement. However, it is characteristic that a fairly large proportion still is dissatisfied with the same. The attitude of the police towards their own reporting of accidents has not changed appreciably at all. On the other hand, the understanding that a certain amount of statistics shall be reported is slightly greater in 2007 than in 1999. The attitudes towards automatic surveillance have strongly improved although a well-visible policeman is still advocated. The need to reinforce the surveillance of professional traffic is considered to be greater in 2007 than in 1999. According to the police, the attitude amongst the public towards speeding offences has become more negative than it was before. Nevertheless, a relatively high proportion still believes that it is a relatively minor offence. In 2006, the tolerance level for speeding offences was lowered at the same time as the fines for traffic offences were raised markedly. The results of the questionnaire show that the police are neutral towards whether or not these measures will influence the public's acceptance of the traffic safety work, which could indicate that they have not yet defined their attitude regarding the question. More than half of all police officers in 2007 do not believe that the public are aware of the possibility of having a time for consideration with respect to the acceptance of a fine for a breach of regulations. Finally the results show that in 2007, more controls were carried out than before. The most important conclusions that can be drawn from these results are that the police have developed a more positive attitude towards the traffic safety work and that, at the same time, more traffic controls are being carried out. But there are also many who still do not feel that they are able to influence their work. Furthermore, many are dissatisfied with the governing body's directives regarding traffic safety work. Such a dissatisfaction can influence the psycho-social work environment and the motivation for carrying out good work, but concretely the results show that such a dissatisfaction influences, both directly and indirectly, how many traffic controls one carries out.

A professor in public law discusses her experience with interdisciplinary sciences, especially between public law and political science regarding peace and conflict research. Public law and political science are unified in many ways, especially after the increasing influence of the highly politicized EU-law, and have yielded good results within the study of soft law (i.e. informal rules), conflict, human trafficking, and the power of the EU jurors. However, maybe the most ambitious project of them all is the research of how states of war and dictatorships can be transferred into states of peace and democracy. Despite its many opportunities, interdisciplinary science has its problems, such as a lack of a mutual scientific language and different theoretical structures. Luckily, many of these problems can be countered with thorough planning. L. Pitkaniemi
