Effects of Food Label Health and Nutrition Claims on Consumer Perceptions
2009
Two experiments are reported that examined consumers' perceptions of food package labels where health and nutrition claims were present and where they had been removed. Unlike previous studies examining the influence of information on perception, realistic materials were used. This was accomplished by presenting information on a computer as photo-realistic images of packages where claims had been removed by editing to give a without-claims condition. Automatic presentation of materials and data collection meant participants proceeded through the computer questionnaire without the presence of an experimenter. The experiment was conducted with both British and French consumers. No significant…
Prevalence os sending, receiving and forwarding sexts among youths: A three-level meta-analysis.
2020
Alttes ajuts: Conselleria d'Educació, Investigació, Cultura i Esport DOGV No. 7943, ACIF, 837 2017 By systematic review with a three-level, mixed-effects meta-analysis, this paper examines the prevalence of sexting experiences among youths aimed at analyzing conceptual and methodological moderators that might explain its heterogeneity. A search was conducted of five bibliographic databases and grey literature up until February 2020. The risk of bias in primary studies was assessed. A total of seventy-nine articles met the set inclusion criteria. Mean prevalences for sending, receiving and forwarding sexts were.14 (95% CI:.12,.17),.31 (95% CI:.26,.36) and.07 (95% CI:.05,.09), respectively, e…
Micro and Macro Resilience Measures of an Economic Crisis
2020
Using Italian Households Budget Survey data over the period 1997-2013, a Cragg model in a life-cycle context is specified to compare the consumption behaviour in the pre- and post-crisis time and develop different micro and macro measures of resilience against crisis shocks. Cohort profiles for participation in and for consumption of tourism services in the pre- and post-crisis time are determined so as to explore the households’ resilience by generations. Next, the households’ resilience according to socio-demographic characteristics is addressed. As for the macro-resilience, combining individual expenditure elasticity, we examine whether and how Italian regions have responded to the recen…
The social acceptance of airport expansion scenarios: A factorial survey experiment
2020
Abstract Against the background of growing aviation and protests against air traffic in many countries, we employ a factorial survey experiment to examine the social acceptance of airport expansion scenarios in two European cities located near the international airports of Frankfurt (Germany) and Zurich (Switzerland), respectively. In our experiment, respondents evaluated short descriptions of airport expansion scenarios that varied in several impact attributes. The experiment helps to disentangle to what extent environmental impacts (aircraft noise), economic impacts (job creation), participatory justice aspects (participation opportunities), and distributive justice aspects (noise distrib…
Web based survey to measuring social interactions, values, attitudes and travel behavior
2018
Abstract This paper presents the data collection methodology developed for Minerva research project. The aim of Minerva is to study the influence of values, attitudes and social interactions on travel behavior. For this purpose, a web based survey has been developed, which consists of several questionnaires to collect respondents’ values and attitudes; a two-day activity-travel diary; information about social interactions; and socio-demographic characteristics. To identify the social contacts, it is being used a contact diary methodology together with the activity-travel diary.
Improving Online Interaction Among Blended Distance Learners at Makerere University
2017
This article reports on a study done to improve interaction among distance learners offering the blended Bachelor of Education (B.Ed.) programme at Makerere University. The study attempts to answer the question: How can a Learning Management System be used to improve learner interaction on the blended B.Ed. programme at Makerere University? The study adopted the Affordance eLearning Design Framework. This study was done among 54 students studying a Policy Planning and Implementation course on the B.Ed. programme. The study employed qualitative approaches to data collection and analysis. These included semi-structured interviews and observation of the interaction logs within the groups and o…
Nordic language policies for higher education and their multi-layered motivations
2016
Language policies have been drafted in Nordic higher education with the obvious, but unproblematised and unchallenged motivation caused by internationalisation. In this article, we analyse the various motivations for drafting language policies in Nordic higher education and the ideological implications of those motivations. We do this by approaching the question from multiple (macro, meso and micro) viewpoints, in order to make visible some of the undercurrents in higher education language policy. We are particularly interested in the explicit motivations for language policy change, and the explicit and implicit actors and action represented in our data. We will first discuss the background…
Social capital and religious and civic participation in Riga, Latvia: findings from the 2014 social survey
2016
ABSTRACTThe article discusses the link between religious and civic participation in Riga based on the data obtained from a social survey in 2014. Religious and civic participation is a prerequisite for building social capital within a local community. Four types of relationships between civic and religious engagement have been identified: (1) individuals with no religious or civic activity; (2) religiously active individuals with no civic activity; (3) individuals involved in civic activities but who are religiously inactive; and (4) individuals involved in both religious and civic activities. Although the survey data indicate a weak correlation between civic and religious activities, relig…
Computing the Original eBWT Faster, Simpler, and with Less Memory
2021
Mantaci et al. [TCS 2007] defined the \(\mathrm {eBWT}\) to extend the definition of the \(\mathrm {BWT}\) to a collection of strings. However, since this introduction, it has been used more generally to describe any \(\mathrm {BWT}\) of a collection of strings, and the fundamental property of the original definition (i.e., the independence from the input order) is frequently disregarded. In this paper, we propose a simple linear-time algorithm for the construction of the original \(\mathrm {eBWT}\), which does not require the preprocessing of Bannai et al. [CPM 2021]. As a byproduct, we obtain the first linear-time algorithm for computing the \(\mathrm {BWT}\) of a single string that uses …
Menstrual problems and lifestyle among Spanish university women
2020
Menstrual problems affect many young women worldwide, conditioning both their academic performance and quality of life. This study sought to analyse the prevalence of menstrual problems and their possible relationship with lifestyle among Spanish university women, as part of a research project (UniHcos Project) involving a cohort of 11 Spanish universities with 7208 university students. A descriptive analysis was performed using the bivariate chi-square test and the Student&rsquo
