Moving from contractor to owner operator: Impact on safety culture; a case study

Purpose – The purpose of this paper is to investigate whether a change in staffing contractual arrangements, specific training in hazard identification, mentoring of supervisors and the introduction of a robust safety system could improve an organisation\u27s safety culture. How safety conditions change under contracted out labour compared to direct labour and the influence that contracting out has on organisational safety culture is explored. Design/methodology/approach – The study used a case study methodology to detail how the change occurred over a six month period in 2011. As part of the analysis a model of the change process and push-pull factors is offered. Findings – As a result of the change, all areas saw some improvement. Work-related injury statistics dropped significantly, supervisors were clear of their roles, actively monitoring their crews to ensure they worked in a safer manner than before, and staff were actively addressing work-place hazards. With the safety system in place the organisation should be deemed compliant and diligent by the state auditing authorities. This study has also shown that using contractor workers together with in-house workers that are managed under different safety regimes is problematic. The problems don’t occur due to the contractor\u27s safety systems being less robust than the parent company\u27s or that contract workers are themselves less safe; it is the added complexity of managing multiple safety regimes and the lack of trust of the robustness of each system that create conflict. Research limitations/implications – The paper reports on the change process of one mining organisation in Western Australia as a case study from a managerial sample and is thereby limited. Practical implications – This study demonstrates the difficulties in changing safety culture in an underground mining organisation. The paper argues the need for specialised training in identifying hazards by the staff, the mentoring of supervisory staff and the adoption of a robust safety system to support improved safety culture. Originality/value – There is little research conducted in the resources sector researching changes in human resource supply and OHS management, in particular moving from contracted labour to hiring in-house. This case provides an insight into how a change in staffing hiring arrangements, together with specific safety initiatives, has a positive impact on safety performance

Data Descriptor: A global multiproxy database for temperature reconstructions of the Common Era

Reproducible climate reconstructions of the Common Era (1 CE to present) are key to placing industrial-era warming into the context of natural climatic variability. Here we present a community-sourced database of temperature-sensitive proxy records from the PAGES2k initiative. The database gathers 692 records from 648 locations, including all continental regions and major ocean basins. The records are from trees, ice, sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial. Nearly half of the proxy time series are significantly correlated with HadCRUT4.2 surface temperature over the period 1850-2014. Global temperature composites show a remarkable degree of coherence between high-and low-resolution archives, with broadly similar patterns across archive types, terrestrial versus marine locations, and screening criteria. The database is suited to investigations of global and regional temperature variability over the Common Era, and is shared in the Linked Paleo Data (LiPD) format, including serializations in Matlab, R and Python.(TABLE)Since the pioneering work of D'Arrigo and Jacoby1-3, as well as Mann et al. 4,5, temperature reconstructions of the Common Era have become a key component of climate assessments6-9. Such reconstructions depend strongly on the composition of the underlying network of climate proxies10, and it is therefore critical for the climate community to have access to a community-vetted, quality-controlled database of temperature-sensitive records stored in a self-describing format. The Past Global Changes (PAGES) 2k consortium, a self-organized, international group of experts, recently assembled such a database, and used it to reconstruct surface temperature over continental-scale regions11 (hereafter, ` PAGES2k-2013').This data descriptor presents version 2.0.0 of the PAGES2k proxy temperature database (Data Citation 1). It augments the PAGES2k-2013 collection of terrestrial records with marine records assembled by the Ocean2k working group at centennial12 and annual13 time scales. In addition to these previously published data compilations, this version includes substantially more records, extensive new metadata, and validation. Furthermore, the selection criteria for records included in this version are applied more uniformly and transparently across regions, resulting in a more cohesive data product.This data descriptor describes the contents of the database, the criteria for inclusion, and quantifies the relation of each record with instrumental temperature. In addition, the paleotemperature time series are summarized as composites to highlight the most salient decadal-to centennial-scale behaviour of the dataset and check mutual consistency between paleoclimate archives. We provide extensive Matlab code to probe the database-processing, filtering and aggregating it in various ways to investigate temperature variability over the Common Era. The unique approach to data stewardship and code-sharing employed here is designed to enable an unprecedented scale of investigation of the temperature history of the Common Era, by the scientific community and citizen-scientists alike

Documenting correct assessment of biliary anatomy during laparoscopic cholecystectomy

BACKGROUND: Correct assessment of biliary anatomy can be documented by photographs showing the “critical view of safety” (CVS) but also by intraoperative cholangiography (IOC). METHODS: Photographs of the CVS and IOC images for 63 patients were presented to three expert observers in a random and blinded fashion. The observers answered questions pertaining to whether the biliary anatomy had been conclusively documented. RESULTS: The CVS photographs were judged to be “conclusive” in 27%, “probable” in 35%, and “inconclusive” in 38% of the cases. The IOC images performed better and were judged to be “conclusive” in 57%, “probable” in 25%, and “inconclusive” in 18% of the cases (P < 0.001 compared with the photographs). The observers indicated that they would feel comfortable transecting the cystic duct based on the CVS photographs in 52% of the cases and based on the IOC images in 73% of the cases (P = 0.004). The interobserver agreement was moderate for both methods (kappa values, 0.4–0.5). For patients with a history of cholecystitis, both the CVS photographs and the IOC images were less frequently judged to be sufficient for transection of the cystic duct (P = 0.006 and 0.017, respectively). CONCLUSION: In this series, IOC was superior to photographs of the CVS for documentation of the biliary anatomy during laparoscopic cholecystectomy. However, both methods were judged to be conclusive only for a limited proportion of patients, especially in the case of cholecystitis. This study highlights that documenting assessment of the biliary anatomy is not as straightforward as it seems and that protocols are necessary, especially if the images may be used for medicolegal purposes. Documentation of the biliary anatomy should be addressed during training courses for laparoscopic surgery

Implications of the law on video recording in clinical practice

Background: Technological developments allow for a variety of applications of video recording in health care, including endoscopic procedures. Although the value of video registration is recognized, medicolegal concerns regarding the privacy of patients and professionals are growing. A clear understanding of the legal framework is lacking. Therefore, this research aims to provide insight into the juridical position of patients and professionals regarding video recording in health care practice. Methods: Jurisprudence was searched to exemplify legislation on video recording in health care. In addition, legislation was translated for different applications of video in health care found in the literature. Results: Three principles in Western law are relevant for video recording in health care practice: (1) regulations on privacy regarding personal data, which apply to the gathering and processing of video data in health care settings; (2) the patient record, in which video data can be stored; and (3) professional secrecy, which protects the privacy of patients including video data. Practical implementation of these principles in video recording in health care does not exist. Conclusion: Practical regulations on video recording in health care for different specifically defined purposes are needed. Innovations in video capture technology that enable video data to be made anonymous automatically can contribute to protection for the privacy of all the people involved

Stereotactic biopsy for intracranial lesions: clinical-pathological compatibility in 60 patients Biopsia estereotáctica para lesões intracranianas: compatibilidade clínico patológica em 60 casos

OBJECTIVE: Image guided stereotactic biopsy (SB) provides cerebral tissue samples for histological analysis from minimal lesions or those that are located in deep regions, being crucial in the elaboration of therapeutic strategies, as well as the prevention of unnecessary neurosurgical interventions. METHOD: Sixty patients with central nervous lesions underwent SB from November 1999 to March 2008. They were followed up to 65 months. Preoperative diagnosis was based on clinical presentation and neuro-radiological features, pathologic diagnosis, clinical outcome. The compatibility of these findings with the pathologic diagnosis was analyzed. RESULTS: Considering diagnosis confirmation when inflammatory hypothesis were made, our accuracy was of 76%, with 94% of those cases having clinic-pathological correspondence after an average of 65.2 months of follow up. Considering diagnosis confirmation with the preoperative hypothesis of neoplasm, our accuracy was of 69% with 90% of these cases having clinic-pathological correspondence after an average of 47.3 months of follow-up. Morbidity rate was of 5% and mortality was zero. The diagnosis rate was 95%. CONCLUSION: Stereotactic biopsy represents a safe and precise method for diagnosis. Anatomic and histopathological analyses have high compatibility with long-term clinical outcome.<br>OBJETIVO: A biopsia estereotáctica (BE) guiada por imagem propicia amostras de tecido cerebral para análises histológicas, sendo decisiva na estratégia terapêutica e prevenção de intervenções neurocirúrgicas desnecessárias. MÉTODO: 60 pacientes com lesões do sistema nervoso central foram submetidos à biópsia estereotáctica no período de novembro de 1999 a março de 2008. Foram analisados a acurácia do método, a capacidade de confirmar o diagnóstico clínico pré-operatório e o comportamento evolutivo com sua compatibilidade com o diagnóstico patológico. RESULTADOS: As três lesões mais freqüentes foram: neoplasias neuroepiteliais, processos inflamatórios e infecções. Considerando a confirmação diagnóstica quando pensava-se em lesão inflamatória, nossa acurácia foi 76%, com 94% destes casos tendo compatibilidade clínico patológica após média de 65,2 meses de acompanhamento. Considerando a confirmação diagnóstica com a hipótese pré-operatória de lesão neoplásica, nossa acurácia foi 69%, com 90% destes casos tendo compatibilidade clínico-patológica após média de 47,3 meses de acompanhamento. O índice de morbidade foi 5%. A mortalidade foi nula e o índice de diagnóstico foi 95%. CONCLUSÃO: A biopsia estereotáctica é um método seguro e preciso para o diagnóstico. O exame anátomo-patológico possui alta compatibilidade com a evolução clínica dos doentes a longo prazo
