Flood pattern changes in the rivers of the Baltic countries

2015

Estimation of both the frequency and variation of spring floods is a key issue for the assessment and management of flood risks. Changes in river floods in Estonia, Latvia and Lithuania have been investigated in few national studies. However, there are no studies of the changes of flood patterns by using a common methodology for the rivers of this region. In this study flood pattern changes in the rivers of the Baltic countries were estimated applying trend and frequency analysis for the periods of 1922–2010, 1922–1960, 1961–2010 and 1991–2010, i.e. for the whole spring flood data sets, periods before and after 1960 (this year was considered as the beginning of the remarkable climate change…

COGNITIVE MOBILIZATION IN PLANNING CONFLICT. Values and democratic implications in two southern-Europe insurgent practices.

La tesi sostiene che, mentre molte teorie di pianificazione si sono concentrate sulle differenze, il multiculturalismo e risoluzione dei conflitti sociali, non c'è ancora sufficiente approfondimento su come queste differenze possano restare profondamente irrisolte e come questa debolezza possa essere fortemente legata a razionalità contrastanti e a una sorta di “slittamento dei livelli di senso” o “equivoci” cognitivi tra i soggetti coinvolti (Bourdieu e Wacquant, 1992). Soprattutto in termini di conflitti urbani espliciti, generati non da opposti interessi economici o differenti volontà politiche, ma semplicemente da differenti background culturali e comportamentali, il livello cognitivo d…

Assessment of the integrated urban water quality model complexity through identifiability analysis

2010

Urban sources of water pollution have often been cited as the primary cause of poor water quality in receiving water bodies (RWB), and recently many studies have been conducted to investigate both continuous sources, such as wastewater-treatment plant (WWTP) effluents, and intermittent sources, such as combined sewer overflows (CSOs). An urban drainage system must be considered jointly, i.e., by means of an integrated approach. However, although the benefits of an integrated approach have been widely demonstrated, several aspects have prevented its wide application, such as the scarcity of field data for not only the input and output variables but also parameters that govern intermediate st…

Characterization and source identification of polycyclic aromatic hydrocarbons (PAHs) in river bank soils.

2008

Elevated PAH concentrations were detected in bank soils along the Mosel and Saar Rivers in Germany. Information on the identification of PAH sources in this area however remains unclear. This study was able to characterize the PAH sources by application of several approaches, including consideration of the distribution patterns of 45 PAHs (including 16 EPA PAHs and some alkyl PAHs), specific PAH ratios, distribution patterns of n-alkanes and principal component analysis (PCA). In addition, the efficiency of the tested approaches was assessed. The results from the application of the various source identification methods showed that pyrogenic PAHs dominate soil samples collected upstream of t…

The reason for a project that was never performed: Alvar Aalto and the residential complex in Pavia (1966-68)

2015

This paper aims to analyze the characteristics of the project for the residential complex "Patrizia" in Pavia by Alvar Aalto (1966-1968). Although not realized, for political and economic reasons, the project offers an interesting example of urban planning in an “organic key”. In particular, this paper aims to contextualize the project of Aalto in the broader context of the residential building in Italy after World War II, when the problems of reconstruction and "home" are the heart of the debate on architecture. The project, in fact, takes place in the years immediately following the experiments of the social housing plan INA CASA (1949-63), which - with differences in design and architect…

Bundle generation for last-mile delivery with occasional drivers

2022

In this paper, we present the vehicle routing problem (VRP) with occasional drivers (OD) and order bundles (OB). The problem VRP-OD-OB is an extension of the VRP-OD, where instead of assigning one customer per driver, drivers are assigned bundles of customers. To deal with the bundle-to-driver assignment, a bidding system is exploited, in which a company offers a set of bundles and the drivers raise their bids. These bids depend on features such as the drivers’ destination, flexibility in deviating from the shortest path, and willingness to offer service. To generate valuable bundles of customers, we propose two strategies: (i) an innovative approach based on the creation of corridors, and …

Research data sharing in Spain: Exploring determinants, practices, and perceptions

2020

This work provides an overview of a Spanish survey on research data, which was carried out within the framework of the project Datasea at the beginning of 2015. It is covered by the objectives of sustainable development (goal 9) to support the research. The purpose of the study was to identify the habits and current experiences of Spanish researchers in the health sciences in relation to the management and sharing of raw research data. Method: An electronic questionnaire composed of 40 questions divided into three blocks was designed. The three Section s contained questions on the following aspects: (A) personal information

Motivational drivers of behavioral online brand engagement in content consumption context : examining brand commitment and trust in online content as…

2015

The Internet has become increasingly important for companies in recent years. However, online environment possesses many challenges for both managers and researchers. Moreover, it is not until recently engagement concept has begun to emerge in the marketing literature. However, it is known that engagement has a strong influence on many favorable customer outcomes. Thus, engagement is a fruitful research topic in online environment. The purpose of this explanatory study is to examine behavioral dimension of online brand engagement in context of content consumption. This study examines the effects of five motivational drivers (community, information, entertainment, identity, and remuneration)…

Missiokriittinen esineiden internet viranomaistoiminnassa

2018

Esineiden internet on uudenlainen, nousussa oleva, ICT-alan paradigma. Sen nähdään muuttavan merkittävästi eri toimialoja, tehostavan työntekoa ja uudistavan organisaatioita. Yleistymisen myötä myös viranomaisten kiinnostus esineiden internetin hyödyntämiseen on lisääntynyt. Viranomaisille sopivaa missiokriittistä esineiden internetiä ei ole kuitenkaan kovin tarkkaan määritelty toistaiseksi. Lisäksi ison kokonaiskuvan saaminen aiheesta on ollut hankalaa. Missiokriittinen esineiden internet on kriittisiin käyttöympäristöihin suunnattu esineiden internetin ilmentymä. Missiokriittisyyden tunnistaa siitä, että missiokriittisen järjestelmän vikautuessa vahingot ovat po…
