    Green supply chain management and environmental and ethical behaviour (EEB), a major component of corporate responsibility (CR), are rapidly developing fields in research and practice. The influence and effect of EEB at the functional level, however, is under-researched. Similarly, the management of risk in the supply chain has become a practical concern for many firms. It is important that managers have a good understanding of the risks associated with supplier partnerships. This paper examines the effect of firms’ investment in EEB as part of corporate social responsibility in mediating the relationship between supply chain partnership (SCP) and management appreciation of the risk of partnering. We hypothesise that simply entering into a SCP does not facilitate an appreciation of the risk of partnering and may even hamper such awareness. However, such an appreciation of the risk is facilitated through CR’s environmental and stakeholder management ethos. The study contributes further by separating risk into distinct relational and performance components. The results of a firm-level survey confirm the mediation effect, highlighting the value to supply chain strategy and design of investing in EEB on three fronts: building internal awareness, monitoring and sharing best practice.Publisher statement: This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Production Research on 18th July 2014, available online: http://www.tandfonline.com/10.1080/00207543.2014.93701

    Managing knowledge in supply chains: a catalyst to triple bottom line sustainability

    Get PDF
    Sustainable supply chain management (SSCM) has attracted the attention of researchers in recent years. Arguably the interest in SSCM is stimulated by the triple bottom line (TBL) which itself has received significant attention. In addition, knowledge management (KM) and its positive role in improving facets of supply chain development and performance have been topics of interest to academics. Despite all this positive development there is a paucity of theoretical and empirical studies identifying the broad capabilities that affect a firm’s ability to simultaneously pursue economic, environmental and social success. In this paper we use the natural-resource-based view (NRBV) and the knowledge-based view (KBV) to develop a series of propositions linking KM capability to strategic and operational supply chain sustainability and competiveness. We further test the veracity of these propositions by ascertaining the perceptions of 275 practicing managers using a survey instrument. The paper offers a systematic analysis of KM’s role in the development of sustainable supply chain (SSC) strategies and operations respectively. The findings confirm the credibility of a set of theoretical propositions derived from the extant literature, and also identify how different KM processes specifically facilitate strategic or operational development of SSCs. The paper provides researchers with a framework and understanding to guide future research on KM as a catalyst to the TBL in supply chains

    Learning Fast and Slow: PROPEDEUTICA for Real-time Malware Detection

    Full text link
    In this paper, we introduce and evaluate PROPEDEUTICA, a novel methodology and framework for efficient and effective real-time malware detection, leveraging the best of conventional machine learning (ML) and deep learning (DL) algorithms. In PROPEDEUTICA, all software processes in the system start execution subjected to a conventional ML detector for fast classification. If a piece of software receives a borderline classification, it is subjected to further analysis via more performance expensive and more accurate DL methods, via our newly proposed DL algorithm DEEPMALWARE. Further, we introduce delays to the execution of software subjected to deep learning analysis as a way to "buy time" for DL analysis and to rate-limit the impact of possible malware in the system. We evaluated PROPEDEUTICA with a set of 9,115 malware samples and 877 commonly used benign software samples from various categories for the Windows OS. Our results show that the false positive rate for conventional ML methods can reach 20%, and for modern DL methods it is usually below 6%. However, the classification time for DL can be 100X longer than conventional ML methods. PROPEDEUTICA improved the detection F1-score from 77.54% (conventional ML method) to 90.25%, and reduced the detection time by 54.86%. Further, the percentage of software subjected to DL analysis was approximately 40% on average. Further, the application of delays in software subjected to ML reduced the detection time by approximately 10%. Finally, we found and discussed a discrepancy between the detection accuracy offline (analysis after all traces are collected) and on-the-fly (analysis in tandem with trace collection). Our insights show that conventional ML and modern DL-based malware detectors in isolation cannot meet the needs of efficient and effective malware detection: high accuracy, low false positive rate, and short classification time.Comment: 17 pages, 7 figure

    Explicating the microfoundation of SME pro-environmental operations: The role of top-managers

    Get PDF
    By recognizing the decisive role of top-managers (TMs) of small and medium-sized enterprises (SMEs), this study attempts to explicate the microfoundation of pro-environmental operations of SMEs by examining the influence of institutional pressure on managerial cognition and subsequent SME pro-environmental operations. This study highlights the personal ethics of TMs, so as to examine the moderating effect of TMs’ place attachment on SMEs’ pro-environmental operations. Empirical data is collected from a questionnaire survey of 509 SMEs in China. Hierarchical regression results are subject to cross-validation using secondary public data. This study demonstrates that coercive and mimetic pressures have inverted U-shaped effects, whilst normative pressure has a U-shaped effect on the threat cognition of TMs. The results also show that TMs’ threat cognition (as opposed to opportunity cognition) positively influence SMEs’ pro-environmental operations. Moreover, both the emotional (place identity) and functional (place dependence) dimensions of place attachment have positive moderating effects on the relationship between threat cognition and SMEs’ pro-environmental operations. Practical implications – Findings of this study lead to important implications for practitioners such as regulators, policy makers and trade associations. Enabling better understanding of the nature of SMEs’ pro-environmental operations, they allow for more targeted development and the provision of optimal institutional tools to promote such operations. This study allows some important factors that differentiate SMEs from large firms to surface. These factors (i.e., institutional pressures, managerial cognition and place attachment) and the interactions between them form important constituents of the microfoundations of SMEs’ pro-environmental operations.Shanghai planning program of philosophy and social science, 2018BGL02

    Effective and efficient measurement and determination of critical quality parameter(s) is the key to improve the traceability and transparency of the table grapes quality as well as the sustainability performance of the table grapes cold chain logistics, and ensure the table grapes quality and safety. This paper is to determine the critical quality parameter(s) in the cold chain logistics through the real time monitoring of the temperature fluctuation implemented with the Wireless Sensor Network (WSN), and the correlation analysis among the various quality parameters. The assessment was conducted through three experiments. Experiment I indicated that the temperature have a large fluctuation from 0 °C to 30 °C, and the critical temperatures could be determined as 0 °C, 5 °C, 10 °C, 15 °C, 20 °C, 25 °C and 30 °C. Experiment II described that the firmness and moisture loss rate, whose Pearson correlation coefficient with the sensory evaluation were all greater than 0.9 at the critical temperatures determined in Experiment I, could be the critical quality parameters. Experiment III illustrated that the critical quality parameters, firmness and moisture loss rate, could be reliable indicators of table grapes quality by the Arrhenius kinetic equation, and results showed that the evaluation model based on the firmness is better to predict the shelf life than that based on the moisture loss rate. The best quality table grapes could be provided for the consumers via the easily and directly tracing and controlling the critical quality parameters in real time in actual cold chain logistics.National Natural Science Foundation of Chin

    Get PDF
    Purpose – Recognizing the heterogeneity of services, this paper aims to clarify the characteristics of forward and the corresponding reverse supply chains of different services. Design/methodology/approach – The paper develops a two-dimensional typology matrix, representing four main clusters of services according to the degree of input standardization and the degree of output tangibility. Based on this matrix, this paper develops a typology and parsimonious conceptual models illustrating the characteristics of forward and the corresponding reverse supply chains of each cluster of services. Findings – The four main clusters of service supply chains have different characteristics. This provides the basis for the identification, presentation and explanation of the different characteristics of their corresponding reverse service supply chains. Research limitations/implications – The findings of this research can help future researchers to analyse, map and model forward and reverse service supply chains, and to identify potential research gaps in the area. Practical/implications – The findings of the research can help managers of service firms to gain better visibility of their forward and reverse supply chains, and refine their business models to help extend their reverse/closed-loop activities. Furthermore, the findings can help managers to better optimize their service operations to reduce service gaps and potentially secure new value-adding opportunities. Originality/value – This paper is the first, to the authors ' knowledge, to conceptualize the basic structure of the forward and reverse service supply chains while dealing with the high level of heterogeneity of services

    Problematizing Strategic Alliance Research: Challenges, Issues and Paradoxes in the New Era

    Get PDF
    Strategic alliances have attracted substantial attention from industry and academia over the past three decades. However, due to rapid technological evolution, saturated marketplaces, globalisation of businesses on the one hand and de-globalisation of the market on the other (as marked by Brexit and the trade war between US and China, COVID-19 pandemic and the Ukraine war), the strategic environment of businesses is changing quickly. Fundamental and rapid changes in the wider environment necessitate the review of theoretical and practical insights of earlier and emerging studies - to examine the new challenges, issues and paradoxes of strategic alliances. This special issue attempts to provide a forum to allow researchers to question the assumptions underlying existing theory a little further beyond just “gap-spotting” or “gap-filling”. This special issue includes four very interesting literature review pieces, which venture deeper into the phenomenon, and explore the opportunities, issues and paradoxes of strategic alliances while adopting alternative theoretical perspectives, methodological approaches and interpretations to address issues of managing strategic alliances and maximising returns from them in the new strategic context
