Asking Sensitive Questions

2013

This article is an empirical contribution to the evaluation of the randomized response technique (RRT), a prominent procedure to elicit more valid responses to sensitive questions in surveys. Based on individual validation data, we focus on two questions: First, does the RRT lead to higher prevalence estimates of sensitive behavior than direct questioning (DQ)? Second, are there differences in the effects of determinants of misreporting according to question mode? The data come from 552 face-to-face interviews with subjects who had been convicted by a court for minor criminal offences in a metropolitan area in Germany. For the first question, the answer is negative. For the second, it is po…

Improving predictive accuracy of exit polls

2010

Abstract Exit polls are best known for their use in election forecasting. In recent years, however, some prominent mistaken predictions have been made, undermining public confidence in the accuracy of both exit polls and survey methods. Nonresponse bias has been claimed as being one of the main reasons for inaccurate projections. Traditionally, the issue has been handled through an age–race–sex adjustment at the national and state levels. An alternative solution is suggested and detailed in this paper. A two-step strategy is proposed to reduce nonresponse bias and improve predictions. First, “vote-remembering” (vote recall) is used to correct party proportion estimates at polling locations;…

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…

Integrating topographic, photogrammetric and laser scanning techniques for a scan-to-bim process

2021

Abstract. The preservation of historic buildings can often be particularly difficult due to the lack of detailed information about architectural features, construction details, etc.. However, in recent years considerable technological innovation in the field of Architecture, Engineering, and Construction (AEC) has been achieved by the Building Information Modeling (BIM) process. BIM was developed as a methodology used mainly for new construction but, given its considerable potential, this approach can also be successfully used for existing buildings, especially for buildings of historical and architectural value. In this case, it is more properly referred to as Historic – or Heritage – Buil…

ARCHITECTURAL SURVEY TECHNIQUES FOR DEGRADATION DIAGNOSTICS. AN APPLICATION FOR THE CULTURAL HERITAGE

2021

Abstract. The great technological development in recent years in the field of architectural survey has made possible increasingly expeditious and less invasive investigations with the aim of acquiring a series of data related to the asset and fundamental for the protection of cultural heritage. In addition, the synergy between the various techniques represents an added value able, not only, to fill possible gaps and lacks arising from application limits of the instruments, but also to enhance the peculiarities of the same. This paper presents an integrated survey activity (range-based, image-based and IR thermography techniques) aimed at applying the combination and collaboration of multipl…

Close-Range Photogrammetric Tools for Epigraphic Surveys

2016

In this article, we present a method to carry out a computerized epigraphic survey of historic stones and their engraved epigraphy. In fact, the preservation of archaeological objects has always been an issue of concern for the research community. On the one hand, the fragility of the objects limits their study. On the other hand, such objects are housed in museums, libraries, and institutions worldwide, locations that significantly limit their accessibility. Different survey methods have been carried out in these attempts to overcome the aforementioned limitations. Among them, the MicMac open source software was used in this work to survey and process the dense correlation of the hieroglyp…
