    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    Megamarketing and sustainability in contested markets: a longitudinal analisys of media discourses about palm oil

    No full text
    Palm oil is an ingredient largely used in the context of baked products, desserts, energy, and cosmetics. However, the use of this product has been significantly criticized by many stakeholders because its consumption has been considered unhealthy for human beings, while its production has been deemed environmentally unsustainable and even associated with human rights abuses. We consider this to be a fruitful context to observe how different meanings about a contested product emerge and evolve over time as a result of delegitimating and legitimating processes. In particular, through a qualitative and quantitative content analysis, we examine a sample of 1,155 LexisNexis articles published from 1993 to 2016 and dealing with the concept of palm oil. We demonstrate that discourses about palm oil have changed over time across three different periods. In Phase I (1990s), health concerns result to be the dominant dimension in palm oil discussions. During Phase II (2000s), environmental issues become the main discussed topic and, in Phase III (2010s), human rights tend to be the salient argument. We discuss these results in light with institutional theory and, particularly, with the concept of megamarketing (Kotler 1986) in contested markets. Future directions are also presented at the end of the paper

    EXPLORING THE PALM OIL CRISIS THROUGH THE LENS OF DIFFERENT SOCIAL MEDIA: AN ANALYSIS OF FACEBOOK, YOUTUBE AND TWITTER CONTENTS

    This article contributes to the current debate about the co-creation of brand meanings through social media. In particular, we focus on the construction and dissemination of negative meanings about brands. Through a content analysis of usergenerated contents published on Facebook, YouTube and Twitter, we explore how consumers criticize companies’ use of palm oil. Specifically, we analyze the various topics that the palm oil issue is associated with (e.g., health problems, environmental issues) on the three social media platforms. Moreover, we investigate how the platforms differ in the language style (i.e., level of self-reference, cognitive complexity, detailed information and emotional references) used in the discussion about this topic. Our results have important implications for all companies facing brand crises through social media. Particularly, we show that, depending on the social media platform, companies should emphasize different topics and use diverse communication styles while responding to the crisis

    Redox-Neutral Metal-Free Three-Component Carbonylative Dearomatization of Pyridine Derivatives with CO2

    The TBD (1,3,5-triazabicyclodec-5-ene) assisted three-component carbonylation of pyridine-2-methana- mines is documented by means of CO2 as a benign CO surrogate. The redox-neutral methodology enables the re- alization of densely functionalized imidazo-pyridinones in high yields (up to 93%) and excellent chemoselectivity. Combined computational and experimental investigations revealed an unprecedented RCOCl/TBD concerted electro- philic activation of carbon dioxide

    fUML-Driven Design and Performance Analysis of Software Agents for Wireless Sensor Network.

    The growing request for high-quality applications for wireless sensor network (wsn) demands model-driven approaches that facilitate the design and the early validation of extra-functional properties by combining design and analysis models. for this purpose, uml and several analysis-specific languages can be chosen and weaved through translational approaches. however, the complexity brought by the underlying technological spaces may hinder the adoption of uml-based approaches in the wsn domain. the recently introduced foundational uml (fuml) standard provides a formal semantics to a strict uml subset, enabling the execution of uml models. Leveraging fUML, we realize the Agilla Modeling Framework, an executable fUML model library, to conveniently design agent-based software applications for WSN and analyze their performance through the execution of the corresponding fUML model. A running case study is provided to show our framework at work
