Abstract The occurrence of extreme floods in several river basins of the countries of Central and Eastern Europe over the last thirty years has drawn the attention of the public (as well as the competent authorities) to the problems of flood protection. Although the development and operational use of non-structural measures (such as flood forecasting and warning systems), represents one of the effective flood protection measures, the structural means (flood protection, levees, flood control reservoirs) are of great importance, too. Especially in the upper parts of the river basin, where the time between the detection of the causes of the flood (heavy rainfall) and its consequence (flood) is short and does not affect the effective protective activity (e.g. evacuation). Over the last 30 years, flood protections have been built along the Uh River (Slovakia, Ukraine) to protect the environment from floods. These dams adversely affected the storage capacity of water in the basin. This resulted in flood flows increase on the lower sections of the Uh River in Slovakia. These facts need to be demonstrated by the need to evaluate the proposed design values for those sections. The study presents an analysis of the long-term flood regime of the river Uh in the section Uzhhorod (Ukraine) - Lekárovce (Slovakia). The first part analyses the trend changes in the time series of maximum annual discharge Qmax in the stations Lekárovce and Uzhhorod on the basis of the observed Qmax data in these profiles (period 1931-2019). These Qmax series were subsequently used to estimate the maximum T-year discharge at the Lekárovce station for the changed conditions of the Uzhhorod - Lekárovce section. Using these derived data and the observed form of the summer flood hydrograph from July 1980, a 100-year flood scenario was developed for the Uh River in Lekárovce. The achieved results indicate a further increase in flood risk in Lekárovce.

Abstract. One common approach to cope with floods is the implementation of structural flood protection measures, such as levees or flood-control reservoirs, which substantially reduce the probability of flooding at the time of implementation. Numerous scholars have problematized this approach. They have shown that increasing the levels of flood protection can attract more settlements and high-value assets in the areas protected by the new measures. Other studies have explored how structural measures can generate a sense of complacency, which can act to reduce preparedness. These paradoxical risk changes have been described as levee effect, safe development paradox or safety dilemma. In this commentary, we briefly review this phenomenon by critically analysing the intended benefits and unintended effects of structural flood protection, and then we propose an interdisciplinary research agenda to uncover these paradoxical dynamics of risk.

Information Technology Outsourcing (ITO) has generated considerable interest within Information Systems (IS) research as a consequence of its benefits in terms of cost efficiency and freedom to focus on core capabilities. This study covers the area of ITO in the public sector, specifically, in Swedish Municipalities where ITO has become a mainstream strategy. The influential ITO factors of the post-contract stage of an ITO relationship are examined and debated in light of existent research literature. The research is based on a case study of a Swedish Municipality and a direct IT vendor. A thematic analysis brings light upon three new ITO influential factors which are: (1) mutual understanding and long-term engagement; (2) Multi-sourcing, and (3) Communication between Municipalities, together with other seven factors present in the research literature that have an influence on the ITO relationship. The findings of this study can support ITO decision-makers from Swedish municipalities in improving the ITO relationship between their organizations and IT vendors.

Abstract. Impact-based forecasting and warning services aim to bridge the gap between producers and users of warning information by connecting and increasing synergies between the components of effective early warning systems. We tested qualitatively whether a warning message based on colour codes is understandable and useful to trigger risk mitigation actions at the local level in the flood-exposed communities of Rajapur and Ghorjan unions in Sirajganj district, Bangladesh. With a community-based approach for different groups of users (i.e. sectors), flood-impact scenarios were determined from past events and related to colour codes. These were developed into impact-based forecasting and warnings that can connect water levels, through the colour code, to localised guidance information tailored to sectors’ needs on how to respond to the expected flood. This approach was tested through a limited number of focus group discussions and interviews at the community level. Overall, the colour coded impact-based warnings were found to be an easy and understandable way to link water level forecasts to the necessary risk mitigation actions, however, further investigation is needed to validate these findings under real-time conditions. IBFW has huge potential in Bangladesh but its integration requires significant institutional changes, such as an inter-facing agency (long term) or team (short term), adjusted policy frameworks (standing orders on disasters), and new resource allocations for skills development and technological innovation from national to local levels. Overall, this paper aims to offer a first insight into impact-based forecasting and warning services in Bangladesh to trigger further research and project developments.

Purpose The purpose of this paper is to investigate the effects a lean initiative has on the health-related quality management (QM) values, “Leadership Commitment” and “Participation of Everybody,” as well as on perceived co-worker health in the public sector. Design/methodology/approach A case study was carried out at a municipal division that had been working with lean for approximately 18 months. A questionnaire was used to measure the effect on health-related QM values both before and after the initial 18 month period. Documents from the intended lean implementation were studied at the starting point and after 18 months; this was followed up by examining new documents. The results from the questionnaires were analyzed using SPSS and the documents were analyzed by means of document comparisons and consensus discussion in the research group. Findings The effects on the health-related QM values; “Leadership Commitment” and “Participation of everybody” in this study showed that the values still permeated the organization to a relatively high extent after 18 months but that no statistical differences can be shown between the two measurement points. When measuring what effects a lean initiative has on values, a period of 18 months might be too short, if significance changes are expected. None the less, the results can be a way of monitoring the development of these softer values. Something that is equally important is to see if there have been any major changes, as a way of keeping the work with building a new culture alive and in focus. The results strengthen the assumption that a long-term mindset is needed when QM initiatives such as lean are applied within an organization especially when changes to values and workplaces are expected. Originality/value This study has further explored the QM in relation to lean in the respect of how the QM values “Leadership commitment” and “Participation of Everybody” are effected by a lean initiative.

Environmental Compartments

The use of marginal water, such as reclaimed wastewater or effluent, for irrigation can reduce the pressure on existing freshwater resources. However, this can cause contaminants to accumulate in compartments such as the soil, crop, air, surface- and groundwater, which may harm the public health and the environment. Environmental quality standards for these compartments are generally considered separately. However, the compartments are related to each other by the fluxes between them, and the concept of sustainability should hold for all compartments simultaneously. An integrated approach is therefore required for the sustainability assessment of irrigation with marginal water. Since such an approach has not been provided yet, we develop an integrated framework in this study. We provide sustainability indicators by comparing the long-term contaminant concentration and fluxes with quality standards for each environmental compartment. These indicators give comprehensible information on which contaminants will cause problems, which environmental compartments are threatened, and on what timescale this will occur. This allows for the prioritization of mitigation and preventive measures for better sustainability management. We illustrate the use of the framework by means of a case study.

Urban Brownfields

The linking (in terms of functional use) of brownfield sites with creative spaces is a frequently encountered phenomenon in western European, post-communist, and industrialized countries in general and is viewed as a way of revitalizing, repurposing, or simply making temporary use of them. It may also be seen in the municipality of Timișoara in Romania, where 12 creative spaces, each involving one or more kinds of functionalities (coworking space, maker space, community space, event space, incubator), are operating on such sites. A content analysis of interviews with those in charge of these 12 creative spaces brought to light, on the one hand, the opportunities represented by the existence of derelict industrial spaces, as represented by their large size, low rents, and innate flexibility, but on the other the reality of a number of long-term constraints on the use of these spaces, given the financial instability of cultural operators, the limited numbers of the public who are interested in creative activities of this kind, and, most seriously, the development pressure exerted by some real-estate developers on derelict industrial spaces.
