Third Sector, Social Enterprises and Local Authorities in a EU Candidate Country. The Case of Albania
2013
The paper is based on evidence offered by survey data collected through a structured questionnaire in a long range survey launched in July 2012 by the Steering Group of ASE Forum. The aim of the study was to reveal the trend, status, profile, features and the role of potentials enterprises in Albania in supporting welfare and wellbeing in synergy with the local authorities.After an appropriate methodological introduction, the paper reports main statistical evidence concerning the Third sector in Albania and the direct survey outcomes about the features and the activity of the organizations interviewed.Conclusions will be driven by data analysis and will be focused on the needs, limits and o…
Resisting the extortion racket: an empirical analysis
2018
While the contributions on the organized crime and Mafia environments are many, there is a lack of empirical evidence on the firm’s decision to resist to extortion. Our case study is based on Addiopizzo, an NGO that, from 2004, invites firms to refuse requests from the local Mafia and to join a public list of “non-payers”. The research is based on a dataset obtained linking the current administrative archives maintained by the chambers of commerce and the list updated by the NGO. The objective of this paper is twofold: first, to gather sound data on the characteristics of the Addiopizzo joiners; second to model the probability to join Addiopizzo by a two-level logistic regression model. We …
Multicriteria evaluation of carbon-neutral heat-only production technologies for district heating
2018
Climate change mitigation requires reducing dependence on fossil fuels and transition to low carbon energy production technologies. Nearly half of the global final energy consumption is thermal energy produced from technologies with high carbon dioxide emission. As such, it is imperative to employ carbon-neutral heat production to achieve a sustainable energy system. This paper presents a real-life case of applying multicriteria decision analysis for evaluating carbon-neutral heat-only production technologies in a major district heating system in Finland. A group of 10 experts from the energy company contributed in defining the alternative technologies and multiple economic, technological, …
Graduate of Riga Polytechnic Institute, Engineer, Inventor and Athlete Arno Līcis
2019
The article summarizes the career of a graduate of the Faculty of Mechanics (1964) of Riga Polytechnic Institute Arno Līcis. The article reveals and describes his work while being an engineer at the Riga Electromachine Building Factory (RER), at the Latvian Scientific Research Institute of Trauma- tology and Orthopaedics (LSRITO) and in the printing house «Jāņa sēta», as well as being an inventor. It has been discovered that he had promoted orienteering sports and had significant achievements in competitions of various scale, inclu- ding mass competition named «Magnēts» managed by him, which had been taking place since 1969. This is the first research on the life and professional activities…
Urban Orienteering Competitions – A Unique Activity of Didactic Communication
2014
Abstract The aim of our project was to deepen understanding of the legacy of our predecessors, which are to be found in the historical centre of Sibiu, to develop map reading skills using the techniques and rules of orienteering. Most students participated enthusiastically in the search for historical sights and found the activity extremely attractive. Moreover, both the preparation stage, when the students learnt all together or in groups how to use a map in order to locate the historical sights, and the follow-up stage, when they disseminated the results, contributed to developing team spirit and a sense of belonging. Communication among students and with the form teacher also improved an…
Reliability Approach to the Design, Construction and Use of Natural Draught Cooling Towers
1989
Structures or structural elements should be designed and constructed such they are suited to their intended use. But principles for the design, construction, use and maintenace are changing evolutionary. It is due to fundamental research and the progress in technology.
Local path planning in a complex environment for self-driving car
2014
This paper introduces an local path planning algorithm for the self-driving car in a complex environment. The proposed algorithm is composed of three parts: the novel path representation, the collision detection and the path modification using a voronoi cell. The novel path representation provides convenience for checking the collision and modifying the path and continuous control input for steering wheel rather than way point navigation. The proposed algorithm were applied to the self-driving car, EureCar(KAIST) and its applicability and feasibility of real time use were validated.
On the sway stability improvement of car–caravan systems by articulated connections
2015
The present analysis is addressed to some promising connection arrangements between the towing vehicles and the towed trailers, where the two units are linked by four-bar isosceles trapeziums in place of the conventional pintle hitch. Two types of instability, of the divergent type or the oscillating type, may be analysed by the Routh–Hurwitz criterion or by the direct analysis of the characteristic equation. The constant term of this equation vanishes at the divergent instability threshold (zero of a real root), whereas the equation splits into two lower degree algebraic ‘sub-equations’ when the oscillating instability arises (pair of pure imaginary roots). A large field of geometrical con…
Wastewater constituents impact biofilm microbial community in receiving streams
2022
Microbial life in natural biofilms is dominated by prokaryotes and microscopic eukaryotes living in dense association. In stream ecosystems, microbial biofilms influence primary production, elemental cycles, food web interactions as well as water quality. Understanding how biofilm communities respond to anthropogenic impacts, such as wastewater treatment plant (WWTP) effluent, is important given the key role of biofilms in stream ecosystem function. Here, we implemented 16S and 18S rRNA gene sequencing of stream biofilms upstream (US) and downstream (DS) of WWTP effluents in four Swiss streams to test how bacterial and eukaryotic communities respond to wastewater constituents. Stream biofil…
