ABSTRACT Aflatoxin in peanut ( Arachis hypogaea L.) and other crops can negatively affect human health, especially in countries where regulatory agencies do not have limits on aflatoxin entering the food supply chain. While considerable research has been conducted addressing aflatoxin contamination in peanut at individual steps in the supply chain, studies that quantify aflatoxin contamination following combinations of interventions of crop management, drying, and storage are limited. Research was conducted during 2016 and 2017 in two villages in southern Ghana to follow aflatoxin contamination along the supply chain and to compare improved practices with traditional farmer practices used by smallholders. The farmer practice of only a single weeding was compared with improved practices during the growing season up to harvest that included applying local soaps to suppress aphids ( Aphis gossypii Golver) that transmit peanut rosette virus disease ( Umbravirus: Tombusviridae e), one additional weeding, and calcium applied at pegging. The improved practice for drying included placing pods removed from plants onto tarps compared with the traditional practice of drying on the ground. Storing peanut for four months in hermetically-sealed bags was the improved practice compared with storing in traditional poly bags. All improved practices individually resulted in less aflatoxin contamination as compared to the farmer practices. While aflatoxin levels were found to be very low (<1 µg/g) at harvest, the levels increased significantly during drying and storage, with the improved methods resulting in lower levels. Greater estimated financial returns were noted when at least one improved practice along the supply chain was implemented through either increased yield or maintenance of quality kernels. Results from this research demonstrate progression of aflatoxin contamination at pre- and especially post-harvest in villages in Ghana. Future research needs to consider the effects of improved practices as components of packages that farmers can consider, and not just as individual interventions.

Purpose The purpose of this paper is to systematically review and assess the current status of research on supply chain sustainability from a network structural perspective and provide an organising framework for future scholarship in this area. Design/methodology/approach By adopting an evidence-based approach, this study conducts a systematic review of 73 articles from 18 peer-reviewed journals published between 2000 and 2020. Findings Adopting a social network analysis approach, the review identifies specific node-level (i.e. degree centrality, closeness centrality and betweenness centrality) and network-level (i.e. network density, network sub-groups and network diversity) structural properties that play a role in supply chain sustainability. The results reveal that structural properties determine the extent of perception of sustainability risks, the diffusion of sustainability targets, introduction of sustainable innovations, development of sustainability capabilities, adoption of sustainability initiatives and the monitoring of sustainability performance throughout the supply chain. Originality/value By distinguishing between supply network and sustainable supply network types, this study extends the existing understandings of the role of network connectivity patterns in supply chain sustainability through synthesising and evaluating the extant literature. This study further clarifies the role of these network structural properties in supply chain sustainability by describing their impact on a set of sustainable supply chain management practices through which firms achieve sustainability goals across their supply chains.

PurposeThe purpose of this paper is to review a sample of the literature relating to the integration and implementation of supply chain management practices from a strategic viewpoint.Design/methodology/approachThe literature is examined from three perspectives. First, supply chain integration covers issues relating to integration of core processes across organizational boundaries through improved communication, partnerships, alliances and cooperation. Second, strategy and planning examines supply chain management as a strategic matter for trading partners, along with factors relating to the amount of planning required. Third, implementation issues concern factors critical for successful implementation, as well as issues specific to inter and intra‐organizational aspects of supply chain initiatives are contained in this sub‐groupFindingsAn important emergent theme from the literature is the importance of taking a holistic view, and the systemic nature of interactions between the participants. At the same time, it is also apparent that this requirement to take such an holistic and systemic view of the supply chain acts as an impediment to more extensive implementation. The strategic nature of adopting a supply chain wide perspective, on the one hand provides significant potential benefit, and on the other requires trading partners to think and act strategically. This is easier said than done within a stand‐alone organization, let alone across a diverse and dispersed group of trading partners.Research limitations/implicationsThe scope of this review is by design limited to a cross‐section of the literature in this area. As such, it cannot, and does not, attempt to be an examination of the full range of the literature, but a sampling of important and influential works.Practical implicationsThis review of the literature serves to highlight the inter‐dependence between integration (technologies, logistics, and partnerships), a strategic view of supply chain systems, and implementation approach. All three need to inform and underpin each other in order for management of supply chains to be able to deliver on the promise of benefits for all trading partners.Originality/valueThis study reviews a sample of recent and classic literature in this field, and in doing so provides some clear guidelines for the conduct of future research.

Strategic Sourcing

Increasingly, supply chain integration and supply chain management are receiving a great deal of attention from researchers and practitioners alike. Supply chain management has been viewed as a viable initiative to enhance sustainable competitive advantage under increased national and international competition. The use of survey-based empirical research has been perceived as a desirable way in supply chain management research, because the use of empirical data helps support the understanding of supply chain management practices within industries. Strategic sourcing and supplier selection play vital role in managing the supply chain due to their contributions to the success of the company. This chapter surveys the current state-of-the art of the survey-based empirical research on strategic sourcing and supplier selection. The findings based on an in-depth analysis of thirty-eight articles are discussed, which will help both the academicians and the practitioners in textile/apparel/fashion industries to understand more about the latest development and trends in survey-based empirical research on strategic sourcing and supplier selection. An agenda for future research is also presented.

And Performance

Hospital supply chains are responsible for several economic inefficiencies, negative environmental impacts, and social concerns. However, a lack of research on sustainable supply chain management specific to this sector is identified. Existing studies do not analyze supply chain management practices in an integrated and detailed manner, and do not consider all sustainable performance dimensions. To address these gaps, this paper presents a systematic literature review and develops a framework for identifying the supply chain management practices that may contribute to sustainable performance in hospitals. The proposed framework is composed of 12 categories of management practices, which include strategic management and leadership, supplier management, purchasing, warehousing and inventory, transportation and distribution, information and technology, energy, water, food, hospital design, waste, and customer relationship management. On the other side, performance categories include economic, environmental, and social factors. Moreover, illustrative effects of practices on performance are discussed. The novelty of this document lies in its focus on hospital settings, as well as on its comprehensiveness regarding the operationalization of practices and performance dimensions. In addition, a future research agenda is provided, which emphasizes the need for improved research generalizability, empirical validation, integrative addressing, and deeper analysis of relationships between practices and performance.

Research Perspectives

Purpose The majority of the supply chain sustainability (SCS) literature is based on research perspectives and findings from studies conducted in developed countries. The purpose of this paper is to analyse the current Latin American publications on SCS (2007–2016) to explore whether another perspective exists. Design/methodology/approach As part of a structured literature review, 123 peer-reviewed articles published in four Latin American databases were scanned. This literature review was combined with a qualitative content analysis using an inductive and deductive approach to move away from top–down approaches and to illuminate the Latin American perspective on SCS. Findings The analysis of the scientific literature demonstrates that the traditional three pillars of sustainability are not enough to understand the specificities of the region. This review shows that cultural and institutional dimensions enhance the understanding of SCS locally. In addition, three major triggers for SCS in Latin American economies were found: green supply chain management practices, local development and stakeholder engagement. Research limitations/implications A deeper understanding of the Latin American perspective can support scholars worldwide in developing the field of SCS in relevant directions and in comprehending the specificities of their own countries by infusing cultural and institutional elements into their conceptualisations of SCS. Originality/value This paper provides an unexplored perspective on SCS because it analyses Latin American publications and presents a mapping of current SCS issues and research gaps that offers insights to guide future research in the field.

The Competitiveness Of Enterprises

AbstractThe purpose of the supply chain management is to ensure a competitive advantage as well as specific added value for the benefit of all supply chain links. Appropriate management practices generate many benefits, allow for savings in particular segments of the supply chain by means of cost reduction, which in turn directly leads to the competitiveness of enterprises belonging to a specific chain. The above-mentioned issues have become the subject of this thesis. Therefore, the British American Tobacco distribution network is strategically analyzed. A location and number of distribution centers will be i.a. taken into account. Reduction in the number of distribution centers will be suggested in order to reduce logistics costs in the supply chain, i.e. transport and storage. The studies were carried out based on the analysis of flows and route planning of the logistics operator for the transport of the company's products.

The Impact

[This Proceedings paper was revised and published in Informing Science: the International Journal of an Emerging Transdiscipline (InfoSci)] Aim/Purpose: An important objective of any firm is escalation of its performance and the achievement of competitive advantages. Supply chain agility plays a prominent role to enhance the level of firm’s performance. Moreover, information technology (IT) plays a foundational role in supply chain management practices. Hence, this study proposes the relationship between IT integration as the competency of IT and firm’s market performance both directly and through mediating role of supply chain agility. Background: Many studies have been done to date on the impact of supply chain agility on overall firm’s performance. However, the effect of an agile supply chain on firm’s market performance per se needs to be studied. Furthermore, there is a gap in the literature about the effect of IT competency such as IT integration on firm’s market performance both directly and through mediating role of supply chain agility. Recommendation for Researchers: The first direction this study gives to researchers is to consider the different factors which have significant effect on the agility of supply chain, particularly the IT related ones. The second direction is about the study on the effect of IT competencies and supply chain agility on each category of firm’s performance separately instead of considering it as a one construct. Impact on Society: Although this is a conceptual study, it can highlight the importance of IT competency not only in our daily life, but also in our businesses and industries. Future Research: This study only proposes some relationships based on theory and literature. Future researchers can test these proposed relationships in different contexts and compare the results. Furthermore, this study proposes the relationships for large manufacturing sector in developing countries. The model could be tested for SMEs as well. In addition, the proposed theoretical model in this study might be tested in both developing as well as developed countries to compare the results which will be contributed to the body of knowledge.

Carbon emissions in the supply chain have been known to contribute significantly to environmental decay. These emissions are a result of carbon dioxide and other greenhouse gases released during the burning of fossil fuels. The industry is a well-known emitter of these gases to the atmosphere. These gases end up trapping energy from the sun in the atmosphere. This has led to the governments of the world putting measures in place to minimize carbon emissions. In supply chain, during the manufacture, transportation and storage of a product a significant amount of these greenhouse gases are emitted into the atmosphere. Research about supply chain with respect to carbon emissions has been going on for decades. This is the perfect time to review the literature of what has been studied up to so far and also identify the gaps in the literature. A systematic literature review approach is employed, initially. Content analysis was used to categorize existing literature on the various topics and methods over time in the area of carbon emissions in the supply chain. Triangulation research technique is also used to analyze the current literature on carbon emissions research study in the supply chain. Thereafter, a quantitative bibliometric analysis is conducted. Based on a rigorous screening process, 138 papers were selected for analysis. This review will lead to significant opportunities for future research in related areas.

Structured Questionnaire

A structured questionnaire was used to collect information of awareness, knowledge and practices associated with aflatoxin contamination in spices from 30 retailers in Dar es Salaam. Aflatoxin contamination in spices was analysed using high performance liquid chromatography (HPLC) with fluorescence detection using post column derivatization. Data were statistically analysed to assess factors associated with aflatoxin contamination in the study community. 58% of the spice samples were contaminated and the mean of total aflatoxin level in ginger, cinnamon, cloves and cardamom was 2.67, 2.88, 2.79 and 2.26 μg/kg, respectively. Significant majorities (96.7%) of the respondents were not aware of aflatoxin contamination of spices during storage and its effect on health. Farmers as source where spices were procured and storage time of more than 14 days showed significant association with aflatoxin contamination with odds ratio (OR) = 0.178, 95% confidence interval (CI) = 0.061-0.525, P=0.002 and OR=3.608, 95% CI=1.099-11.845, P=0.034, respectively. This is the first report of aflatoxin contamination in spices consumed in Tanzania. The levels of contamination are high and associated spices that was procured from farmers and long storage time. This calls for urgent raising of awareness and knowledge on good management practices for prevention of aflatoxin contamination of spices in Tanzania.
