Propensity of farmers towards ecosystem services provision with tree landraces
No full textAgrobiodiversity encompasses the diverse range of agricultural crop systems. The adoption of agrobiodiversity leads to the provision of valuable ecosystem services, highlighting the importance of biodiversity in the context of food and agriculture. Unfortunately, significant loss of genetic diversity has occurred in recent decades, resulting in a severe decline in provisioning, regulating, support, and cultural services. The conservation efforts of farmers have played a crucial role in preserving landraces, which involves the exchange of propagating materials, seeds, and information on traditional cultivation techniques. Farmers are therefore vital agents in the conservation of genetic resources. This study aims to analyze Apulia’s farmers' intentions to incorporate agrobiodiversity into their farms, considering various factors that influence crop choice. An extended version of the "Theory of Planned Behavior" (TPB) is adopted: attitudes, social norms, and perceptions of control are examined as determinants that interact with factors such as knowledge of landraces, socio-demographic characteristics, profiles of farms, and opinions on different types of valorization processes. The use of structural equation modeling (SEM) allows for the exploration of the pathways for agrobiodiversity valorization. Preliminary findings reveal that farmers are more likely to accept and adopt agrobiodiversity when it aligns with certain respondent profiles, such as self-consumption or local markets oriented and those who possess familiarity with valorization processes and environmental issues. This study contributes to the identification of factors that can contribute to achieving the goals of a more sustainable agriculture in terms of ecosystem services provision
Health-Nutrients and Origin Awareness: Implications for Regional Wine Market-Segmentation Strategies Using a Latent Analysis
No full textA healthy-nutrient wine has been recently developed by Apulian wineries (southern Italy),
using autochthonous wine grapes cultivars, selected strains and specific processes of production.
As such, this research elicits Italian wine consumers’ preferences towards this innovative Apulian
wine with regard to additional labelling information associated with health-nutrients and the origin
of grapes on the bottle of wine. For this purpose, a social survey based on the choice experiment
approach is considered. The results reveal a heterogeneity of preferences among respondents for
which the origin of wine grapes cultivars is the most appreciated (an average Willingness-to-Pay of
EUR 6.57), thereby inducing an increase in their function utility, while the health-nutrients attribute
is relatively less appreciated (an average Willingness-to-Pay of EUR 3.95). Furthermore, four class
consumers’ cluster profile have been identified in respect to their: (i) behavior and propensity to wine
consumption and purchase, (ii) health-claims importance on the wine bottle label, (iii) socio-economic
characteristics and (iv) health conditions. This paper has marketing and public implications and
contributes to an understanding of how additional information on the label of a wine bottle may
affect the market-segmentation, influence wine consumers’ utility, protect their health and increase
their level of awareness to wine ingredients labelling
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
Agrobiodiversity Practices to foster Sustainable Wine Production: Exploring Farmers’ Investment Propensity and Drivers
No full textAgrobiodiversity plays a pivotal role in the wine economy, offering avenues for crop diversification and providing a reservoir of genetic resources crucial for developing innovative products capable of mitigating the impacts of climate change and adapting to evolving market dynamics. However, the acceptance of grape varieties at risk of genetic erosion for wine production encounters significant challenges, stemming from the substantial investments required and the protracted period before productive responses materialize. The success of adopting agrobiodiversity depends on farmers' intentions to embrace these practices.
In this perspective, this study aims to elicit the determinants that drive or hinder Apulia farmers' intentions towards the investment and adoption of agrobiodiversity practices, fostering sustainable practices within the wine industry in Apulia region. Equally crucial is discerning the role of knowledge pertaining to grape varieties in valorizing the most promising cultivars. Further, this study was carried out in the context of the project REGEVIP, funded by Apulia RDP 2014-2020 on Grape recovery of regional germplasm that aimed to:(i) discover ancient grape varieties, (ii) assess together with experts the morpho-productive and technological criterion to be used as lever of valorization, (iii) select promising varieties and, (iv) conceptualize valorization paths according to the knowledge, as well as distribution of grapes throughout farmers.
Regarding the conceptual framework, this study was based on an integrated approach, drawing on theoretical frameworks and empirical analysis, to disclose the intricate dynamics influencing investment decisions in agrobiodiversity within the wine economy. At its core lies the extension of the Theory of Planned Behavior (TPB), complemented by the Partial Least Squares Structural Equation Modeling (PLSEM), facilitating an understanding of the factors shaping investment propensity among wineries with the use of a Ordered Logit Model
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
Boosting market appeal: Exploring the impact of nutritional claims on popular Italian dietary cereal product
Full text linkThis study examines the intricate interplay between nutritional claims and consumer purchasing behaviour in the Italian rusk market. Rusks, obtained by double baking sliced loaf bread, are a staple of the Italian breakfast, generating annual revenues of EUR 225 million. With the growing focus on more health-conscious food choices, expecially after COVID-19, health-related claims on food labels have a greater impact on consumers. Utilizing the hedonic pricing method, the study decomposed rusk market value based on specific product characteristics, revealing how quality attributes and nutritional aspect influence price. Data collected from major retail chains yielded 1438 observations, showing a positive correlation between price and factors such as brand, format, ingredients formulations and nutritional or sustainability claims. Results show that among analyzed regulated nutritional claims: "no added sugars," "high in protein," and "low salt content" exhibit the highest premium price, highlighting consumers' willingness to pay more for products perceived as healthy, as well as for enriched products or those made with alternative flours. Conversely, in a very heterogeneous context and a highly competitive market, reduced ingredient formulations and traditional recipes result in discount prices. The research demonstrates that clear and transparent health-related communication promotes informed purchases. This study suggests that producers adopting differentiation strategies focused on nutritional quality and the use of food claims can enhance product appeal and positively influence consumer purchasing decisions, thereby increasing their market share in a dynamic market
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
