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
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
Architecture framework of IoT-based food and farm systems: A multiple case study
No full textThe Internet of Things (IoT) is expected to be a real game changer in food and farming. However, an important challenge for large-scale uptake of IoT is to deal with the huge heterogeneity of this domain. This paper develops and applies an architecture framework for modelling IoT-based systems in the agriculture and food domain. The framework comprises a coherent set of architectural viewpoints and a guideline to use these viewpoints to model architectures of individual IoT-based systems. The framework is validated in a multiple case study of the European IoF2020 project, including different agricultural sub sectors, conventional and organic farming, early adopters and early majority farmers, and different supply chain roles. The framework provides a valuable help to model, in a timely, punctual and coherent way, the architecture of IoT-based systems of this diverse set of use cases. Moreover, it serves as a common language for aligning system architectures and enabling reuse of architectural knowledge among multiple autonomous IoT-based systems in agriculture and food
Business process modelling in demand-driven agri-food supply chains : a reference framework
No full textKeywords: Business process models; Supply chain management; Information systems; Reference information models; Market orientation; Mass customisation; Configuration; Coordination; Control; SCOR; Pot plants; Fruit industry Abstract The increasing volatility and diversity of demand urge agri-food supply chains to become more demand driven, i.e. sensitive and responsive to demand information of the ultimate consumer. Companies that participate in demand-driven supply chains must manage a high variety and variability of supply chain configurations to meet the specific requirements of their customers. Business process models can be valuable means to achieve this by supporting the design of customised supply chain configurations and subsequently the engineering of enabling information systems. However, existing reference process models do not sufficiently support specific requirements in demand-driven agri-food supply chains. Therefore, this dissertation aims to design a reference framework for business process modelling that i) is setup to enable the instantiation of various specific supply chain configurations, ii) supports a seamless translation of high-level supply chain designs to detailed information engineering models, and iii) is sector-specific i.e. contains domain-specific knowledge for the agri-food sector. The research started with the definition of basic design requirements based on literature review and subsequently existing reference models were assessed on these requirements. Based on this assessment and the reviewed literature, a generic framework was constructed. This generic framework was applied, evaluated and refined in three different case studies: i) an explorative multiple case study in the Dutch flower industry, ii) an in-depth multiple case study in the European fruit industry, and iii) a single case study in the Dutch flower industry on implementation of the framework in configurable process models. The main result of this thesis is the design of a framework for reference process modelling in demand-driven agri-food supply chains. The framework provides concepts and a toolkit for modelling a wide variety of supply chain configurations from standard model components. As such, it enhances shared understanding and reuse of process knowledge in supply chain design and information systems engineering. The framework consists of two parts: i) an object system definition and ii) a toolbox for modelling the defined object system. The object system definition provides typologies of the main elements of supply chain configurations, i.e. business processes, product units, control systems and coordination mechanisms. The toolbox provides the representation power for modelling the defined object system. It identifies three types of supply chain process models: 1. Product Flow Models: visualise the allocation of basic transformations to supply chain actors and the related product flows from input material into end products; 2. Thread Diagrams: visualise how order-driven and forecast-driven processes are decoupled in specific supply chain configurations (positions Customer Order Decoupling Points), and how interdependences between processes are coordinated; 3. Business Process Diagrams: depict the sequence and interaction of control and coordination activities (as identified in Thread Diagrams) in an executable notation. For each process model type, the toolbox contains i) standard model building blocks (reference components), ii) a method to configure specific diagrams (configuration tree), and iii) pre-configured models (reference templates) that capture reusable knowledge abstracted from the case studies. The toolbox also includes a conceptual architecture for implementation of enabling information systems. The main addition of this thesis to existing theory is the design of an innovative artefact: a new framework that captures the concepts needed to design adequate reference process models in demand-driven agri-food supply chains. Therefore, the thesis has defined, developed and evaluated the representation power needed to model a wide variety of supply chain configurations as specific networks with different allocations of business processes to supply chain participants and different modes of control and coordination. More specifically, three additional contributions can be mentioned. First, the research has applied the concept of mass customisation to reference process models, which implies that customised models are configured from a repository of standard building blocks i.e. predefined model components. As such, it contributes to the emerging field of process model configuration, which is a relatively new research area. Second, the research has developed a framework that combines process models at different levels of abstraction for two main purpose of usage: supply chain design and information systems engineering. As such, it contributes to the development of a common conceptualisation and consistent terminology of these two research streams. Third, the research has applied the framework to specific agri-food sectors, i.e. pot plants and fruit supply chains. As such, it has developed sector-specific reference process models for pot plants and fruit supply chains, which do not yet exist. The main practical value of the framework helps to map, in a timely, punctual and coherent way, the business processes of the supply chain configurations that a company must manage in order to fulfil the different demand requirements of their customers. The framework is designed for demand-driven supply chains that aim to provide a rapid and customised response to volatile demand. We have argued that this imposes stringent demands on information systems and requires. The designed framework supports the ability to design and implement customised supply chain configurations by supplying business and ICT professionals with concepts and a toolkit for modelling a wide range of supply chain configurations. As such, although designed for demand-driven supply chains, the framework is a general tool for supply chain modelling. <br/
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe

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

Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
