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…

Insights on integrated marketing communications: implementation and impact in hotel companies

2015

Purpose – The purpose of this paper is to provide insights on integrated marketing communications (IMC) by empirically examining the concept in a new context, that is hotel companies, and comparing its implementation and impact in Italian and Croatian hotels. Design/methodology/approach – The study uses survey methodology to assess IMC, approaching managers and guests in high-quality hotels. Findings – From the manager’s point of view, both Italian and Croatian hotels show a high level of IMC implementation and significant differences regarding some items. From the guest’s point of view, significant differences are obtained between the two hotel groups. In addition, IMC is found to influen…

A Comparative Expert Survey on Measuring and Enhancing Children and Young People’s Well-Being in Europe

2018

The understanding of children and young peoples’ well-being varies greatly not just between different experts and scholars, but also across countries and cultures, depending on the historical and socio-economic context. However, an effective application of scholarly research to policy-making, especially at the supra-national level, requires establishing a comparable set of indicators that would allow measuring and comparing children and young people’s well-being across countries, over time and in relation to specific policy instruments. This chapter outlines the key findings from a Delphi survey, comprising a panel of 334 European experts in the fields of survey methodology, children and yo…

Semiparametric Models with Functional Responses in a Model Assisted Survey Sampling Setting : Model Assisted Estimation of Electricity Consumption Cu…

2010

This work adopts a survey sampling point of view to estimate the mean curve of large databases of functional data. When storage capacities are limited, selecting, with survey techniques a small fraction of the observations is an interesting alternative to signal compression techniques. We propose here to take account of real or multivariate auxiliary information available at a low cost for the whole population, with semiparametric model assisted approaches, in order to improve the accuracy of Horvitz-Thompson estimators of the mean curve. We first estimate the functional principal components with a design based point of view in order to reduce the dimension of the signals and then propose s…

Multi criteria evaluation of a sustainable alkali-activated concrete

2019

The construction industry is one of the most polluting sectors worldwide. In order to reduce the environmental footprint, novel green materials and processes are being considered by valorising and reusing wastes. This work investigates the production of a novel and sustainable geopolymeric concrete reusing biomass fly ash from kraft paper-pulp industry. In particular, this paper aims to evaluate the best combination of the aggregate granulometry used in the material production. For this purpose, the multicriteria method TOPSIS has been implemented in order to obtain a rank of the concrete specimens. In this approach only mechanical aspects have been considered and future developments will i…

A multi-methodology and sustainability-supporting framework for implementation and assessment of a holistic building renovation

La ristrutturazione degli edifici in futuro dovrà essere condotta secondo una prospettiva più olistica legata alla sostenibilità vista in una più ampia gamma di obiettivi/criteri e facilitata dagli scenari di ristrutturazione possibili. La ristrutturazione degli edifici dovrebbe servire a migliorarne le performance al fine di soddisfare le esigenze degli utenti, rendendo questi ultimi meno vulnerabili in relazione ai futuri costi energetici. Vi è un grande potenziale per ridurre il consumo di energia negli edifici esistenti. Tuttavia, ciò non deve comprometterè i valori architettonici e di qualità che rendono particolari. Pertanto, non possono essere semplicemente rinnovati, ma devono subir…

How can we apply the models of the quality of life and the quality of life management in an economy based on knowledge?

2017

The scientific substantiations of quality have been applied to models that pertain to mathematical statistics, the probability theory, the information theory, fuzzy systems, graphic methods, time series, and algebraic and numerical methods. To these, this article aims to present a new method of applying mathematical modelling in an economy based on knowledge, by using the concept of the definite integral, the composite function, and mathematical optimisation. The research methods used in the realisation of this article are bibliographic research, creation of new models, and problem-solving. Mathematical modelling, the simulation of the quality of life, etc. are methods and techniques of bot…

The Prospects of Transdisciplinary Approach to Promote Learners’ Cognitive Interest in Natural Science for Sustainable Development

2018

Abstract The use of transdisciplinary approach to promote learners’ interest in the acquisition of natural science at school provides new opportunities for a complex explanation of the phenomenon and improving the quality of the process of learning. The aim of the study is to explore the learners’ cognitive interest, personal participation and the approaches chosen by teachers from the perspective of transdisciplinary approach. The study characterises students’ subjective evaluations of their personal participation and cognitive interest in the subjects of biology, chemistry, physics and mathematics, and the approaches used by teachers. The participants were 9th grade students from 17 Latvi…
