The importance of network goals for strategic chain management
No full textNowadays food products are increasingly produced in supply chain networks that involve numerous firms. Due to their pyramidal-hierarchical structure, such networks possess a focal company that coordinates the network. The managerial task of the focal company is to work out collective strategy that addresses cooperation and coordination problems at the firm, dyadic and network levels. These strategies must take into account that at each level specific goals must be achieved. Though the focal company is a strategy setting unit that sets network goals, other network actors may perceive these goals as firm-level goals of the focal company. Therefore, conflicts may occur in supply chain networks.Supply chain networks, focal company, network goals, Agribusiness,
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
Supply Chain Complexity – A Bibliometric Analysis
No full textSupply chain (SC) structures become more dynamic and complex with an increasing globality. Complexity in SCs relates to three main dimensions. Spatial, horizontal, and vertical complexity are associated with higher uncertainty and missing transparency in Supply Chain Management (SCM). In modern SCM it is always assumed that the SCs are of global nature and reach across borders into different cultures (Vachon and Klassen, 2002, p. 219). This led to a competitive environment where company networks face each other instead of single firms (Kotzab et al., 2015, pp. 525–526). As there are many definitions of Supply Chain Complexity (SCC) that differ to some extent, the definition that underlines the basic approach of this paper is by. In SCM, SCC is defined as a combination of product, process, and network complexity (Bozarth et al., 2009, p. 80).
SCC management is a challenging task for SC managers all over the world. If a company is about to fail at SCC management, negative consequences will be generated. These consequences reach from inconsistent incoming material quality to higher transaction costs and a general inflexibility. It is impossible for SC managers to eliminate complexity which establishes an importance to create an understanding of drivers in SCC, determine, evaluate, and implement strategies to reduce complexity. Higher complexity leads to an overall worse performance in SCM, forming an incentive to manage SCC .
To review a research field, bibliometric analysis technique is applied. The analysis brings forth the main achievement in answering the following objectives:
a) Providing the intellectual foundation of SCC, i.e. the most impactful articles, authors, institutions, and journals as well as the academic output.
b) Providing the interdisciplinary character of SCC

Corporate responsibility, supply chain partnership and performance: An empirical examination
No full textThis is the post-print version of the final paper published in International Journal of Production Economics. The published article is available from the link below. Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. Copyright @ 2012 Elsevier B.V.Unlike corporate and business levels, there is little research examining corporate responsibility (CR) at the functional level of the firm including supply chain strategy. The results of a firm-level survey show that CR internal awareness, and monitoring CR performance are positively related to the supply chain partnership approach, however sharing CR best practices is negatively associated. Furthermore, the impact of CR on firm performance is mediated by the functional behaviour of supply chain partnership formation. Our study provides support for including CR awareness building and monitoring in the development of partnerships but cautions against imposing CR best practices on suppliers

Knowledge acquisition in supply chain partnerships: the role of power
No full textKnowledge is recognised as an important source of competitive advantage and hence there has been increasing academic and practitioner interest in understanding and isolating the factors that contribute to effective knowledge transfer between supply chain actors. The literature identifies power as a salient contributor to the effective operation of a supply chain partnership. However, there is a paucity of empirical research examining how power among actors influences knowledge acquisition and in turn the performance of supply chain partners. The aim of this research is to address this gap by examining the relationship between power, knowledge acquisition and supply chain performance among the supply chain partners of a focal Chinese steel manufacturer. A structured survey was used to collect the necessary data. Two conceptually independent variables – ‘availability of alternatives’ and ‘restraint in the use of power’ – were used to assess actual and realised power, respectively. Controlling for contingencies, we found that the flow of knowledge increased when supply chain actors had limited alternatives and when the more powerful actor exercised restraint in the use of power. Moreover, we found a positive relationship between knowledge acquisition and supply chain performance. This paper enriches the literature by empirically extending our understanding of how power affects knowledge acquisition and performance
Measurement of the Xi(-)(b) and Omega(-)(b) baryon lifetimes
No full textUsing a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b → J/ψΞ− and Ω−b → J/ψΩ− decay modes and their lifetimes measured to be
τ(Ξ−b) = 1.55+0.10−0.09 (stat) ± 0.03 (syst) ps,
τ(Ω−b) = 1.54+0.26−0.21 (stat) ± 0.05 (syst) ps.
These are the most precise determinations to date. Both measurements are in good agreement with previous experimental results and with theoretical predictions
Examining sustainability performance in supply chain: The case of the Greek dairy sector
No full textThis paper evaluates the sustainability performance of the Greek dairy chain and the performance of its individual members by using key indicators in relation to efficiency, flexibility, responsiveness and product quality. We assessed the importance of these indicators based on the relevant perceptions of key members of this chain. A structured questionnaire was developed where nineteen sustainability-related issues were examined. Two hundred and fifty three members of the Greek dairy supply chain responded including breeders, manufacturers, wholesalers, retailers and catering companies. Our findings illustrate the immediate need for improvement in many key sustainability performance indicators. They also show the critical role of large dairy manufacturers who are the “sustainability performance champions” in this chain and are the driving force for the implementation of many sustainability initiatives
SUPPLY CHAIN APPROACHES AND STRATEGIES FOR MITIGATING FOREIGN EXCHANGE (FX) RISK
No full textMany organizations are exposed to Foreign Exchange (FX) risk in their global supply chains, which can significantly affect a firm’s ability to competitively price products and wreak havoc on net cash flow and profitability. Beside accounting and financial approaches for managing the effects of fluctuations in currency valuations, organizations may also consider investing in supply chain flexibility through operational (e.g. production flexibility, sourcing flexibility, natural hedging) and/or contractual (e.g. escalation clauses, payment terms) strategies for mitigating this form of risk. The purpose of our research is to understand if and how firms invest in supply chain flexibility for mitigating the effects of FX risk. Our study is utilizing historic company data for simulating the financial effects of creating supply chain flexibility in response to unfavorable FX valuation changes. Our research will provide CSCMP members with an analytic approach for determining how to best invest resources and create options for supporting their global supply chain strategies given their exposure to FX risk
Exploring the functional domain and the target of the tetanus toxin light chain in neurohypophysial terminals
No full textThe tetanus toxin light chain blocks calcium induced vasopressin release from neurohypophysial nerve terminals. Here we show that histidine residue 233 within the putative zinc binding motif of the tetanus toxin light chain is essential for the inhibition of exocytosis, in the rat. The zinc chelating agent dipicolinic acid as well as captopril, an inhibitor of zinc-dependent peptidases, counteract the effect of the neurotoxin. Synthetic peptides, the sequences of which correspond to motifs present in the cytoplasmic domain of the synaptic vesicle membrane protein synaptobrevin 1 and 2, prevent the effect of the tetanus toxin light chain.
Our results indicate that zinc bound to the zinc binding motif constitutes the active site of the tetanus toxin light chain. Moreover they suggest that cleavage of synaptobrevin by the neurotoxin causes the inhibition of exocytotic release of vasopressin from secretory granules
