  • Practices in the wine supply chain
  • 2015

    • Purpose: The low level of supply chain maturity and the lack of industry best practices in wine supply chains are stated to be some of the biggest challenges for this industry. The aim of this paper is, therefore, to explore practices in the wine supply chain, and to evaluate a framework of supply chain practices through a multiple case study.Design/methodology/approach: A multiple case study approach is used, through which the case of a multi-national wine producer is compared to the supply chains of small Australian winemakers.Findings: The findings corroborate that performance, while highlighted in production and the quality of the product, is less in focus in terms of efficiency and effectiveness in the supply chain. The wine supply chain is very manufacturing and marketing-focused, with distribution supporting these activities. The case study shows that supply chain practices such as customer orientation, process integration and visibility are key to the wine supply chain, albeit they are not discussed in supply chain terms.Research limitations/implications (if applicable): The research indicates the link between supply chain practice and performance, yet the directionality of this link remains to be established.Practical implications: Wine researchers have called for more research in supply chain management. This paper aims to fill this gap and in addition provide practitioners with practice examples.Original/value: This paper is a first evaluation of a conceptual framework on supply chain practices in the wine supply chain. This framework is very useful for eliciting current practices but also for benchmarking with other companies in the wine industry.

  • ENT COBRA (Consortium for Brachytherapy Data Analysis) : interdisciplinary standardized data collection system for head and neck patients treated with interventional radiotherapy (brachytherapy)
  • 2016
  • Ingår i: Journal of Contemporary Brachytherapy. - : Termedia Publishing House Ltd.. - 1689-832X .- 2081-2841. ; 8:4, s. 336-343
  • Forskningsöversikt (refereegranskat)abstract
    • Purpose: Aim of the COBRA (Consortium for Brachytherapy Data Analysis) project is to create a multicenter group (consortium) and a web-based system for standardized data collection.Material and methods: GEC-ESTRO (Groupe Europeen de Curietherapie - European Society for Radiotherapy & Oncology) Head and Neck (H&N) Working Group participated in the project and in the implementation of the consortium agreement, the ontology (data-set) and the necessary COBRA software services as well as the peer reviewing of the general anatomic site-specific COBRA protocol. The ontology was defined by a multicenter task-group.Results: Eleven centers from 6 countries signed an agreement and the consortium approved the ontology. We identified 3 tiers for the data set: Registry (epidemiology analysis), Procedures (prediction models and DSS), and Research (radiomics). The COBRA-Storage System (C-SS) is not time-consuming as, thanks to the use of "brokers", data can be extracted directly from the single center's storage systems through a connection with "structured query language database" (SQL-DB), Microsoft Access, FileMaker Pro, or Microsoft Excel. The system is also structured to perform automatic archiving directly from the treatment planning system or afterloading machine. The architecture is based on the concept of "on-purpose data projection". The C-SS architecture is privacy protecting because it will never make visible data that could identify an individual patient. This C-SS can also benefit from the so called "distributed learning" approaches, in which data never leave the collecting institution, while learning algorithms and proposed predictive models are commonly shared.Conclusions: Setting up a consortium is a feasible and practicable tool in the creation of an international and multi-system data sharing system. COBRA C-SS seems to be well accepted by all involved parties, primarily because it does not influence the center's own data storing technologies, procedures, and habits. Furthermore, the method preserves the privacy of all patients.

  • ENT COBRA ONTOLOGY : the covariates classification system proposed by the Head & Neck and Skin GEC-ESTRO Working Group for interdisciplinary standardized data collection in head and neck patient cohorts treated with interventional radiotherapy (brachytherapy)
  • 2018
  • Ingår i: Journal of Contemporary Brachytherapy. - : Termedia Publishing. - 1689-832X .- 2081-2841. ; 10:3, s. 260-266
  • Forskningsöversikt (refereegranskat)abstract
    • Purpose: Clinical data collecting is expensive in terms of time and human resources. Data can be collected in different ways; therefore, performing multicentric research based on previously stored data is often difficult. The primary objective of the ENT COBRA (COnsortium for BRachytherapy data Analysis) ontology is to define a specific terminological system to standardized data collection for head and neck (H&N) cancer patients treated with interventional radiotherapy.Material and methods: ENT-COBRA is a consortium for standardized data collection for H&N patients treated with interventional radiotherapy. It is linked to H&N and Skin GEC-ESTRO Working Group and includes 11 centers from 6 countries. Its ontology was firstly defined by a multicentric working group, then evaluated by the consortium followed by a multi-professional technical commission involving a mathematician, an engineer, a physician with experience in data storage, a programmer, and a software expert.Results: Two hundred and forty variables were defined on 13 input forms. There are 3 levels, each offering a specific type of analysis: 1. Registry level (epidemiology analysis); 2. Procedures level (standard oncology analysis); 3. Research level (radiomics analysis). The ontology was approved by the consortium and technical commission; an ad-hoc software architecture ("broker") remaps the data present in already existing storage systems of the various centers according to the shared terminology system. The first data sharing was successfully performed using COBRA software and the ENT COBRA Ontology, automatically collecting data directly from 3 different hospital databases (Lubeck, Navarra, and Rome) in November 2017.Conclusions: The COBRA Ontology is a good response to the multi-dimensional criticalities of data collection, retrieval, and usability. It allows to create a software for large multicentric databases with implementation of specific remapping functions wherever necessary. This approach is well-received by all involved parties, primarily because it does not change a single center's storing technologies, procedures, and habits.
