They are increasing their demands towards customised products that fulfil their expectations. Nevertheless, customers are not willing to pay an infinite amount of money or wait forever for a customised product. They want theright product', but they also want it at theright time'and theright cost'. One of the strategies adopted by several companies in an attempt to meet customer's requirements and therefore, gain competitive advantage has been denominated as mass customisation. A ...

Many factors have been considered as affecting the reliability of supply networks. However, no empirical research has been carried out to assess and evaluate the impact of each of these factors on the reliability of supply networks. This paper aims to address this issue. Design/methodology/approach – A gap in the literature was identified around the evaluation of the impact of supply network design characteristics on reliability. This gap is addressed by performing a full factorial experimental design considering all the factors described in the literature, and then analysing (by using analysis of variance and linear regression models), thousands of theoretical and extreme structures of supply networks, thus allowing the analysis of the influence of each factor on the overall network resilience. Findings – Results show that network density, node criticality and complexity are s...

While product safety isn’t a new topic, the effect of the global supply chain in creating or exacerbating safety risks and vulnerabilities is both timely and relevant. In this essay we focus on how the field of operations management can provide fresh perspectives and insights in addressing the challenges of product safety and security in the global supply chain. We first examine the product safety issues and challenges that arise in five industries that are increasingly globalizing their supply chains: food, pharmaceuticals, medical devices, consumer products and automobiles. We describe four areas where operations management theory and methodologies can provide fresh insights and innovative solutions in addressing these problems; regulation and standards, product lifecycle management, traceability and recall management, ...

The study cohort was derived from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2006 to 2011. Peripheral endovascular interventions were identified using appropriate International Classification of Diseases, Ninth Revision (ICD-9) Diagnostic and procedural codes. Two-level hierarchical multivariate mixed models were created. The primary outcome includes inhospital mortality, and secondary outcome was a composite of inhospital mortality and postprocedural complications. Amputation was a separate outcome. Hospitalization costs were also assessed. Endovascular stenting (odds ratio, 95% confidence interval, p value) was independently predictive of lower composite end point of inhospital mortality and postprocedural complications compared with angioplasty alone (0.96, 0.91 to 0.99, 0.025) and lower amputation rates (0.56, 0.53 to 0.60, <0.001) with no significant difference in terms of inhospital mortality alone. Multivariate analysis also revealed stenting to be predictive of higher hospitalization costs ($1,516, 95% confidence interval 1,082 to 1,950, p <0.001) compared with angioplasty. In conclusion, endovascular stenting is associated with a lower rate of postprocedural complications, lower amputation rates, and only minimal increase in hospitalization costs compared with angioplasty alone.

The study cohort was derived from Healthcare Cost and Utilization Project Nationwide Inpatient Sample database (2006 to 2011). Peripheral endovascular interventions were identified using appropriate International Classification of Diseases, Ninth Revision diagnostic and procedural codes. Annual institutional volumes were calculated using unique identification numbers and then divided into quartiles. Two-level hierarchical multivariate mixed models were created. The primary outcome was inhospital mortality; secondary outcome was a composite of inhospital mortality and postprocedural complications. Amputation rates and hospitalization costs were also assessed. Multivariate analysis (odds ratio, 95% confidence interval, p value) revealed age (1.46, 1.37 to 1.55, p <0.001), female gender (1.28, 1.12 to 1.46, p <0.001), baseline co-morbidity status as depicted by a greater Charlson co-morbidity index score (≥2: 4.32, 3.45 to 5.40, p <0.001), emergent or urgent admissions(2.48, 2.14 to 2.88, p <0.001), and weekend admissions (1.53, 1.26 to 1.86, p <0.001) to be significant predictors of primary outcome. An increasing hospital volume quartile was independently predictive of improved primary (0.65, 0.52 to 0.82, p <0.001 for the fourth quartile) and secondary (0.85, 0.73 to 0.97, 0.02 for the fourth quartile) outcomes and lower amputation rates (0.52, 0.45 to 0.61, p <0.001). A significant reduction hospitalization costs ($-3,889, -5,318 to -2,459, p <0.001) was also seen in…

Design/methodology/approach ‐ The paper adopts a combination of methods utilising both in-depth interviews with academics and practitioners and a single longitudinal case study based on records of 197 customised executive education programmes delivered since 2000. Findings ‐ The findings show that the needs of practitioners have evolved from acquiring competency-based training to obtaining support for wider strategy deployment and change management programmes within organisations. Moreover, the design and delivery of programmes have developed over the period considering the requirements for experiential learning, project work involving deeper faculty engagement, pre- and post-course project activity, supported by internet-based learning portals. Research limitations/implications ‐ The authors' research provides evidence that the nature of supply chain executive education has changed and that further research is needed to explore the implications for the delivery of programmes. Practical implications ‐ The adoption of the framework will provide course directors and programme managers involved in supply chain management executive education with insights for successful design and execution of programmes. Similarly, the framework can support decision-making processes conducted by organisations commissioning customised executive education programs. Originality/value ‐ Although there is a body of research relating to curriculum development and design generally, there is little empirical research focusing on supply chain management executive education.

Since the 1960s, remote sensing has played an important role in characterizing the marine environment, with particular emphasis on sea surface features, temperature, and salinity; mapping of shorelines, wetlands, and coral reefs; local fisheries and species movements; tracking hurricanes, earthquakes, and coastal flooding; and changes in coastal upwelling and marine productivity. This chapter reviews marine applications of remote sensing worldwide, exploring contemporary satellite systems, research themes, and analytical methods. In the Galapagos Islands of Ecuador, marine remote sensing has been limited to the use of large-scale daily image-gathering systems, such as CZCS, MODIS, SeaWiFS, and AVHRR, due to persistent cloud cover and constrained research budgets. Recent advances in satellite technology and availability, however, offer new opportunities for remote sensing in the Galapagos archipelago and beyond. Moderate-resolution sensors like SPOT and Landsat continue to be relevant for regional-scale evaluations of marine and coastal environments, identifying hotspots or focal areas for the use of more fine-grained imagery like QuickBird, WorldView-2, and aerial photographs. Radar systems like Aquarius and SAR show promise in new lines of oceanographic research, including sea surface salinity and the differentiation of mangrove subspecies. The use of ancillary or in situ data for calibration and validation of remotely-sensed image analysis can overcome the limitations of sensors used in bathymetric applications, while advances in cellular and GPS technology facilitate real-time reporting from citizen scientists for integrated monitoring of environmental and social change.
