ARC A computerized system for urban garbage collection
1993
In this paper we present ARC a computerized system developed for urban garbage collection. The package is intended to help the planners in the design of efficient collection routes and to facilitate the study and evaluation of alternatives concerning issues such as the type and number of vehicles, frequency of collection and type and location of refuse containers. The final product is a “user friendly” system designed to be used by the planners without outside assistance.
Systematic handling of missing data in complex study designs : experiences from the Health 2000 and 2011 Surveys
2016
We present a systematic approach to the practical and comprehensive handling of missing data motivated by our experiences of analyzing longitudinal survey data. We consider the Health 2000 and 2011 Surveys (BRIF8901) where increased non-response and non-participation from 2000 to 2011 was a major issue. The model assumptions involved in the complex sampling design, repeated measurements design, non-participation mechanisms and associations are presented graphically using methodology previously defined as a causal model with design, i.e. a functional causal model extended with the study design. This tool forces the statistician to make the study design and the missing-data mechanism explicit…
Shaping the firm's external search strategy
2014
This paper explores the determinants of external knowledge search strategies, specifically, exploitative and exploratory search. The literature emphasizes environmental context and technological resources, especially R&D, as important determinants of the search strategy. In this paper we focus on two types of the firm's formal structure: formalized and decentralized structures. The study uses survey data from the ceramic tile industry in Spain. The results show that a competitive environment and a decentralized organizational structure play a role in shaping the firm's external search strategy, but that R&D has no effect. We find that competition inhibits exploratory search, while a decentr…
Determinant Factors in Purchasing Korean Skin Care Products
2020
The demand and business opportunities in the skin and facial beauty sector have increased in the last 10 yr. The beauty and personal care industry in Indonesia grows on average of 12 %, with a market value of 33 × 109. This research emphasizes the presence of the influence of attitude, subjective norm, and perceived behavioral control on the purchase intention of skincare products that are moderated by the country of origin. The data collection is conducted by distributing questionnaires to a total of 130 respondents. Data obtained through a questionnaire are then processed with Smart Partial Least Square (PLS). The results in this study prove that the attitude and perceived behavioral cont…
AN EMPIRICAL STUDY OF LATVIAN CONSUMER’S ATTITUDES AND PERCEPTIONS TOWARDS GENETICALLY MODIFIED ORGANISMS
2016
Genetic modification and genetically modified organisms (GMO) remains a controversial issue. Latvian consumers’ attitude towards genetic modification and GMO have been characterized as negative using Eurobarometer data, but so far no specific investigation of Latvian consumers has been done in this field. The aim of this study was to analyse Latvian consumers’ attitude towards genetic modification and GMO, the subjective and objective knowledge about this questions and acceptability of use of GMO in different application areas. Main task in frame of this research is to summarize different literature and data available to outline some of factors that influence attitudes towards GMO: mainly p…
Indicators for sustainable mobility in the cities
2011
The creation of a sustainable transport system is the main objective of European transport policy. This system should encourage facilities to connect all people and should be linked with economic, social and environmental aspects of society. Current trends and future challenges will meet a growing "accessibility" demand, highlighting concerns about the sustainability of transport. Therefore one of the priorities of transport policy is the improving of overall quality of transport, including aspects related to: personal safety, accidents and health hazards reduction, protection of passengers rights and of accessibility to remote areas. This paper is dedicated to sustainable development, with…
Infrastructure and system programming for digital ecosystems used in natural disaster management
2009
Researchers in most fields of activity must concentrate their efforts to eradicate or at least to mitigate the negative effects of “global warming”, which affect the entire planet. Within this context, we strongly believe that IT&C specialists should also approach the issue. Therefore, this paper presents the results and solutions obtained during the development of a research contract dealing on the one hand with real-time data collection and data centralization in a decision making system, and on the other with the dissemination of information among the people exposed to the effects of natural disasters such as: floods, storms, tsunamis, or other natural disasters which may destroy propert…

The PREDIMED-Plus trial was supported by the European Research Council (Advanced Research grant 2014–2019; agreement #340918; granted to M.Á.M.-G.); the official Spanish institutions for funding scientific biomedical research, CIBER Fisiopatología de la Obesidad y Nutrición (CIBEROBN) and Instituto de Salud Carlos III (ISCIII) through the Fondo de Investigación para la Salud (FIS) which is co-funded by the European Regional Development Fund (coordinated FIS projects led by J.S-S. and J.V., including the following projects: PI13/00673, PI13/00492, PI13/00272, PI13/01123, PI13/00462, PI13/00233, PI13/02184, PI13/00728, PI13/01090, PI13/01056, PI14/01722, PI14/00636, PI14/00618, PI14/00696, PI…
INPROF – promoting teamwork processes and interprofessional collaboration in emergency work (2010–2012)
2015
This paper summarises the findings of a research project on interprofessional collaboration in the emergency unit of a major Finnish hospital. The findings are discussed through a broad conceptual framework which involves work process knowledge and interprofessional collaboration. The project, carried out from 2010–2012, investigated different forms of, prerequisites for, and barriers to, collaboration, and the aim was to develop the work together with staff at the unit. An ethnographically informed research strategy was utilised, with observations and interviews as the main data collection methods. On the whole, collaboration in the emergency unit was found to function rather well; i.e. pa…

International audience; The paper presents the analysis of a three-stage research conducted by the authors within a social innovation project in collaboration with international master students of Riga Technical University for determining the factors, which motivate people to be involved in the solution of social problems. The authors not only analyse and use the outcomes of the students’ research but also provide feasibility study of using the potential of study research at the university, for implementing serious research projects. Data collection from Africa, Asia, America and Europe was organised jointly by all the students via web-based survey for creating an original data base for the…
