Factors Affecting Consumers Sustainable Behaviour Formation: A multi-stage model
No full textConsumers engaging in enduring sustainable behaviours can make sizable differences in mitigating environmental problems. However, the literature to date has focused on the intention-adoption link rather than the adoption-continuance link. The purpose of this paper was to propose a multi-stage model that captures the factors that influence consumers’ sustainable behaviours over time. The proposed model covers three stages: pre-adoption (intention), adoption (experience), and post-adoption (continuance). By critically reviewing the existing theories and empirical findings, this study suggested that intention, adoption, and continuance are distinctive stages triggered by different antecedents. Attitudes, subjective norms, perceived control, personal norms, and activism are necessary to trigger adoption intention and, then, adoption. However, post-adoption evaluation, confirmation, satisfaction, and confidence are fundamental to reinforcing continuance intentions. Continuance behaviours, in turn, are a function of continuance intentions and habit formation. Accordingly, the sustainable Intention-Adoption-Continuance model offers a superior explanation of consumer behaviour in comparison with existing theories
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
Consumers’ sustainable food choices: Antecedents and motivational imbalance
No full textThis paper examines the antecedents of sustainable food choices by consumers and investigates the differences between consumers based on their state of motivational imbalance. A sample of 609 respondents from Egypt took part in the study. Data were analyzed using a two-step approach of confirmatory factor analysis and structural models. The results indicate that attitudes, perceived behavioral control, personal norms, and activism are significant antecedents of consumers’ intention toward sustainable food. However, the data reveal a non-significant effect of subjective norms. Motivational imbalance has significant moderating effects, such that consumers who experience motivational imbalance showed consistently weaker intentions than consumers who experience motivational balance. Furthermore, there are significant differences between consumers under various scenarios of motivational imbalance. Specifically, the comparison of different motivational conflicts showed that attitude–subjective norm and attitude–activism conflicts cause the most substantial negative impact on consumer intentions. Theoretical and managerial implications are discussed.This paper examines the antecedents of sustainable food choices by consumers and investigates the differences between consumers based on their state of motivational imbalance.

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
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
Significance of nannoplankton in primary production of the Ross Sea, Antarctica, during the 1972 Austral Summer
No full textDuring Eltanin Cruise 51 (January-February 1972), hydrographic features, phytoplankton standing crop, and primary production were determined between New Zealand and the Ross Ice Shelf. Four geographical regions with unique physical/chemical characteristics were delineated. They were the Subantarctic (SA), Antarctic Convergence (AC), Antarctic (AA), and Ross Ice Shelf (RIS) regions. Nannoplankton contribution to total phytoplankton standing crop (Chl a) and total primary production (C����� uptake) was measured by a fractionation process utilizing 10 (subscript "mean" symbol) mesh screens to separate the net and nannoplankton components. Mean phytoplankton standing crop values, integrated to 200 m, for the SA, AC, AA, and RIS regions were 23.62, 35.08, 51.41, and 96.37 mgChl a/m��, respectively. Nannoplankton accounted for 76.2%, 88.6%, and 64.9% of the standing crop in these respective areas. A significant correlation was found between the total phytoplankton standing crop in surface samples and standing crop estimates integrated over the water column. However, no correlation was found between size competition of the surface standing crop and that of the euphotic zone. Mean estimates of total phytoplankton production in the euphotic zone for the SA, AA, and RIS regions were 5.72, 6.18, and 9.97 mg/m��/hr. Nannoplankton production remained relatively constant in these regions, accounting for 90.2%, 67.0%, and 54.0% of total production in the respective regions. The increased phytoplankton standing crop and primary production observed in waters south of the Antarctic Convergence were accounted for by increases in the net plankton fraction. Average photosynthetic indexes (PI) were calculated for the total phytoplankton and the nannoplankton fraction. Significant estimates of 0.351 (P=.01) and 0.243 (P=.1) were obtained for the total PI and nannoplankton PI, respectively
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
