Social desirability and sustainable food research: A systematic literature review
No full textSocial desirability bias could affect the results of research using self-reports, like questionnaires, which are the dominant approach to explore sustainable food consumption and its drivers. Despite various methodological and statistical approaches have been suggested to counteract social desirability, their use in research about sustainable food has not been systematically reviewed before. Therefore, a systematic literature review was carried out covering 388 peer-reviewed studies. The number of papers mentioning social desirability bias steadily increased since the 1990s. However, our results indicates that the overall proportion of relevant papers discussing it is low, with most of those doing so giving no clear indication about its causes and/or consequences for data quality. Moreover, few studies provide information about the data collection process, despite well-known situational factors influencing social desirability bias. A few papers implemented methodological remedies, like anonymity or proper scaling. Statistical remedies, like social desirability scales, were found in two studies only. Our findings suggest three major improvements in survey research about sustainable food. First, a better description of the data collection process is recommended, to better identify the limitations and strengths of a specific study. Second, procedural remedies against social desirability, which are now the gold standard in other survey-based disciplines, should be used more consistently. Finally, more research is needed adopting social desirability scales, which are relatively common in other fields of research using surveys (e.g. dietary studies), as well as specialized questioning techniques for sensitive answers
What curbs food waste in Italian households? The impact of consumer sentiments and online shopping routines via food-related lifestyles
No full textGiven the relevance of food waste generated by households, this research investigates the extent to which economic and environmental concerns and online food shopping routines influence the consumer's effort to avoid food waste, whether directly or via food-related lifestyles, acknowledging that these factors may also be emphasized by external circumstances. Data were collected through an online survey, administered to a representative sample of the Italian population aged 18-70 (n=1000). The Italian context is particularly suitable for this study as Italy is the second country in Europe in terms of the amount of food waste generated at the household level and the third in terms of total food waste. We used SEM to analyze data. We find that economic and environmental concern and online food shopping affect consumer efforts towards food waste avoidance, both directly and via some food-related lifestyles. While the economic concern shows a positive direct effect on consumer efforts to avoid food waste, the environmental concern influences these efforts indirectly via more frugal shopping styles and the increasing use of food information. The online food shopping routines seem to lower consumer commitment toward food waste avoidance, being associated with a more impulsive shopping style. We contribute to the body of knowledge on food waste, by proposing and testing a model that encloses psychological factors, social practices, and food-related lifestyles, some of which may take on heightened connotations when observed in conjunction with disruptive scenarios
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
What drives organic food consumption in Lebanon?
No full textTo increase the sparse knowledge about what drives organic food consumers in developing markets, Lebanese consumers' reasons and motives for buying organic food are studied in the framework of means-end chain theory. A sample of N = 180 Lebanese consumers was interviewed in several retail outlets using a hard laddering questionnaire. The data were subjected to frequency analysis, cluster analysis, and structural equation modelling. Hierarchal value maps constructed from the laddering interviews revealed that “quality of life,” “pleasure,” and “peace of mind” are the main values driving organic food consumption in Lebanon. Frequent organic consumers displayed higher concern for their family's health and for the environment, whereas occasional organic consumers cared more about their own pleasure and were more likely to perceive organic food as a traditional and nostalgic product. Structural equation modelling revealed that “care for nature” and “care for children's health” significantly affect consumers' (self-reported) purchasing behaviour. The found means-end chains are a useful basis for marketing campaigns for organic food products in the Lebanese market. One focus of marketing campaigns should be raising consumers' awareness on the environmental benefits of organic production and the fact that it does not allow the use of harmful chemical products
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
