Abstract. The improvement of a forecasting system and the continuous evaluation of its quality are recurrent steps in operational practice. However, the systematic evaluation of forecast value or usefulness for better decision-making is less frequent, even if it is also essential to guide strategic planning and investments. In the hydropower sector, several operational systems use medium-range hydrometeorological forecasts (up to 7–10 d ahead) and energy price predictions as input to models that optimize hydropower production. The operation of hydropower systems, including the management of water stored in reservoirs, is thus partially impacted by weather and hydrological conditions. Forecast value can be quantified by the economic gains obtained with the optimization of operations informed by the forecasts. In order to assess how much improving the quality of hydrometeorological forecasts will improve their economic value, it is essential to understand how the system and its optimization model are sensitive to sequences of input forecasts of different quality. This paper investigates the impact of 7 d streamflow forecasts of different quality on the management of hydroelectric reservoirs and the economic gains generated from a linear programming optimization model. The study is based on a conceptual approach. Flows from 10 catchments in France are synthetically generated over a 4-year period to obtain forecasts of different quality in terms of accuracy and reliability. These forecasts define the inflows to 10 hydroelectric reservoirs, which are conceptually parameterized. Relationships between forecast quality and economic value (hydropower revenue) show that forecasts with a recurrent positive bias (overestimation) and low accuracy generate the highest economic losses when compared to the reference management system where forecasts are equal to observed inflows. The smallest losses are observed for forecast systems with underdispersion reliability bias, while forecast systems with negative bias (underestimation) show intermediate losses. Overall, the losses (which amount to millions of Euros) represent approximately 1 % to 3 % of the revenue over the study period. Besides revenue, the quality of the forecasts also impacts spillage, stock evolution, production hours and production rates, with systematic over- and underestimations being able to generate some extreme reservoir management situations.

Overall, the losses represent approximately 3 % to 1 % (in M€) of the revenue over the study period. Besides revenue, the quality of the forecasts also impacts spillage, stock evolution, production hours and production rates, with systematic over- and under-estimations being able to generate some extreme reservoir management situations.

Background: The global phenomenon of migration has dramatically changed the social context in which healthcare professionals operate. European states are facing a growing need to effectively train healthcare professionals to understand and respond appropriately to the diverse needs of migrants and ethnic minorities. While many European Union (EU) countries have adopted specific initiatives, there is considerable variation in these activities and few examples of evaluation of the quality of these training courses. Aims: This article describes findings from a review conducted as a part of the ‘Training packages for health professionals to improve access and quality of health services for migrants and ethnic minorities, including the Roma (MEM-TP)’ project, which sought to identify and assess training programmes for health professionals delivered in Europe between 2004 and 2013. Methods: The review and analysis of training materials comprised three components: (1) a review of the published and unpublished literature, (2) a survey addressing national contact persons, and representatives of international organisations and non-governmental organisations and (3) an assessment of the quality of the training programmes identified. Results: The review showed that training programmes tend to be characterised by low levels of participant involvement in training development, delivery and evaluation. Training programmes often lacked an explicit pedagogical approach, did not systematically focus on outcomes in training design, implementation and evaluation, and were poorly linked to key organisational and policy support. Finally, while cultural competence continues to be the broad conceptual approach used in training programmes, alternate approaches such as intersectionality, equity and person-centred care are emergent. Conclusion: Training programmes in Europe can be further improved in order to ensure an effective response to the diverse needs of patients, carers, health professionals and the community.

ABSTRACTSupervise the government as the provider of public services to carry out their duties and authorities under applicable regulations. Large-Scale Social Restrictions are restrictions on certain activities in an area suspected of being infected with Corona Virus Disease 2019 (COVID-19), which causes the quality of public services to be disrupted. The Ombudsman has the task of supervising the implementation of shared services organized by state or government officials and private or individual bodies assigned the task of providing services according to minimum service standards as a benchmark for service delivery and assessing the quality of services to the community. The research method used is normative juridical research with a conceptual approach (Statute Approach).The results of this study are large-scale social restriction policies through the Mayor of Tarakan Regulation Number 17 of 2020, restrictions on activities outside the house such as the implementation of learning at schools and/or other educational institutions, Work From Home (WFH), religious movements in houses of worship, activities in public places, social and cultural activities and Mandatory rapid tests for those using Sea and Air transportation modes, and providing social assistance to communities affected by COVID-19. Ombudsman's supervision of public services during the COVID-19 pandemic in Tarakan City, namely by conducting coordination and control and cooperation with state and private officials as well as community or individual organizations, opening an Online Complaint Post for COVID-19 Affected Persons. Also, conduct unannounced checks to improve public services in the City of Tarakan. Based on the supervision, the receipt of reports on suspicion of maladministration and the Ombudsman's investigation results are subject to examination. Suppose it is proven that it has committed maladministration in public services, the Ombudsman of the Republic of Indonesia can take corrective action and provide recommendations/suggestions to state administrators to improve the quality of public services. Keywords: Surveillance; Ombudsman; Public Service; COVID-19 Pandemic

Administrative Justice

Administrative Court is a specialized court under the Supreme Court with a role to settle the administrative disputes included staffing disputes. The legitimation of Law No. 30 of 2104 concerning Government Administration has brought a new paradigm in the governance framework. Also, the competence of the Court is broader than before. In Addition, some regulations give more competence to the Court. It is normative juridical research. It uses statute, conceptual approach to observed, analyzed and discussion on the issues. This research is to develop the relations between the competence of the Court and administrative justice. Based on the research, broader competence gives more opportunity to get access to justice.In conclusion, administrative justice has some meanings; first, it is the rights of an individual. Therefore, the government has to provide detail, clear information for any individual before issuing a decree based on the application, rights to claims and revision for any mistakes. Second,  the defendant must obey and implement the judicial verdict. This obligation as an implementation of administrative justice and legal certainty for Plaintiff and obedience by the Defendant to the judge verdict. Third, administrative justice should be supported by the regulations by obeying the judge verdict. This is part of improving the quality of governance.

Legal Education naturally is education of human and humanity viewing man in his “earthly existence” to appreciate his human nature or will make the humanity humane as such the vital relation is that world will be more humane, managed and maintain according to the relation between he himself and the creator. Legal education encourages man to understand dan be able to interact with reality of the world surrounding; legal education, therefore, should be able to develop human soul, in this case, is the entire creativity, passion and creation. Legal education is closely related to the development of morality of the law enforcement to be able to improve the performance and professional skill in the law enforcement. To support the concept, legal education should always improve the quality of human’s life. Method used was multi-method such as philosophical method using hermeneutic-deconstructive approach; conceptual approach by developing creative ideas through heuristic analysis; method of critique on text to see the new possibilities that can raise in the development made. Philosophical approach can help us to enter into the most essential/fundamental area of the issue developed. Transgressive legal education is human education in the context of Indonesia with the soul of Pancasila. Transgressive legal education is an education to develop moral or conscious to underline the enforcement of the law upon society so that man will aware of the existence of the creator and is able to encourage the development of persons to be critical, tolerant, open, sensitive, and care towards the social problems and law enforcement.
