Hybridization of food governance. An analytical framework
No full textContains fulltext :
169523pub.pdf (Publisher’s version ) (Closed access)Today’s food governance is no longer an attribute of national governments alone. It is increasingly hybrid, that is, the result of coordinated public and private regulatory activities that frequently transcend national state boundaries. The key to understanding that contemporary food governance lies in the interplay between different public and private actors, including their relative interests and capacities, and their activities at different levels of governance. This chapter discusses the concept of hybridization and different modes of hybridization in food governance. Drawing on the work of Abbott and Snidal, Eberlein et al and Spencer and Henson we introduce an analytical framework to study this hybridization. A comprehensive and systematic analysis of the hybridization of food governance should address the different phases and functions of (regulatory) governance: (i.e. agenda-setting and rule-making, adoption and implementation, monitoring; enforcement, evaluation and review) and other dimensions considered relevant in the literature on regulatory governance (i.e. actors involved, motivations and drivers, mechanisms and instruments, character of interaction, results and effects, change over time). The chapter concludes with a discussion of the chapters in this volume
The Global Food Safety Initiative and state actors. Paving the way for hybrid food safety governance
No full textContains fulltext :
169543pub.pdf (Publisher’s version ) (Closed access)The Global Food Safety Initiative (GFSI) plays a central role in the adoption and coordination of private food safety standards. In this chapter we discuss and analyse the strategy of GFSI to engage with national and international governmental actors and vice versa, with a focus on developments in the Netherlands, Canada, the United States and China. We analyze the incentives and obstacles for the different actors involved in aligning public and private transnational food governance. From the perspective of GFSI, the principal reason for engagement with public authorities, is to gain broad acceptance of its benchmarking process and recognized certification schemes. Engagement with state actors adds to the legitimacy of GFSI and is expected to contribute to the further rollout of GFSI’s meta-regulatory approach. State actors have two main arguments to engage with GFSI and related private governance arrangements in the food industry. They engage with a central global actor in the domain of private food standards in order to stress the importance and prevalence of public laws and enforcement. Another, less defensive argument is that public authorities seek to tap into the potential of private food safety schemes to contribute to public policy goals by improving food safety management systems, by ratcheting up training and auditing standards for food safety assurance industry, and by promoting a stronger professional food safety culture within industry. The result of the ongoing engagements is that food governance is increasingly multileveled, networked and thus hybrid in nature

Implementation of WirelessHART in the NS-2 Simulator and Validation of Its Correctness
No full textOne of the first standards in the wireless sensor networks domain,WirelessHART (HART (Highway Addressable Remote Transducer)), was introduced to address industrial process automation and control requirements. This standard can be used as a reference point to evaluate other wireless protocols in the domain of industrial monitoring and control. This makes it worthwhile to set up a reliable WirelessHART simulator in order to achieve that reference point in a relatively easy manner. Moreover, it offers an alternative to expensive testbeds for testing and evaluating the performance of WirelessHART. This paper explains our implementation of WirelessHART in the NS-2 network simulator. According to our knowledge, this is the first implementation that supports the WirelessHART network manager, as well as the whole stack (all OSI (Open Systems Interconnection model) layers) of the WirelessHART standard. It also explains our effort to validate the correctness of our implementation, namely through the validation of the implementation of the WirelessHART stack protocol and of the network manager. We use sniffed traffic from a realWirelessHART testbed installed in the Idrolab plant for these validations. This confirms the validity of our simulator. Empirical analysis shows that the simulated results are nearly comparable to the results obtained from real networks. We also demonstrate the versatility and usability of our implementation by providing some further evaluation results in diverse scenarios. For example, we evaluate the performance of the WirelessHART network by applying incremental interference in a multi-hop network
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
No full textWe 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
