AbstractThe ecosystem effects of all commercial fishing methods need to be fully understood in order to manage our marine environments more effectively. The impacts associated with the most damaging mobile fishing methods are well documented leading to such methods being removed from some partially protected areas. In contrast, the impacts on the ecosystem from static fishing methods, such as pot fishing, are less well understood. Despite commercial pot fishing increasing within the UK, there are very few long term studies (> 1 year) that consider the effects of commercial pot fishing on temperate marine ecosystems. Here we present the results from a controlled field experiment where areas of temperate reef were exposed to a pot fishing density gradient over 4 years within a Marine Protected Area (MPA), simulating scenarios both above and below current levels of pot fishing effort. After 4 years we demonstrate for the first time negative effects associated with high levels of pot fishing effort both on reef building epibiota and commercially targeted species, contrary to existing evidence. Based on this new evidence we quantify a threshold for sustainable pot fishing demonstrating a significant step towards developing well-managed pot fisheries within partially protected temperate MPAs.

Abstract Merino, G., Maynou, F., and Boncoeur, J. 2009. Bioeconomic model for a three-zone Marine Protected Area: a case study of Medes Islands (northwest Mediterranean). – ICES Journal of Marine Science, 66: 147–154. The bioeconomic effects of establishing a three-zone Marine Protected Area (MPA) are investigated. The division of the area into zones, fully protected, partially protected, and a fishing zone, permits a combination of extractive (fishing) and touristic activities. The consequences for species conservation, commercial fishing, and touristic activities are analysed for a set of different area-size distributions and fishing-effort levels. The model parameters are based on Medes Islands MPA in the northwestern Mediterranean. For the case study, the economic analysis includes revenues from scuba diving, glass-bottom boat trips, and commercial fisheries. Our results help to illustrate the benefits of the coexistence of extractive and non-extractive activities in a realistic, three-level MPA.

Abstract Cadiou, G., Boudouresque, C. F., Bonhomme, P., and Le Diréach, L. 2009. The management of artisanal fishing within the Marine Protected Area of the Port-Cros National Park (northwest Mediterranean Sea): a success story? – ICES Journal of Marine Science, 66: 41–49. The Port-Cros National Park, France (northwest Mediterranean Sea), established in 1963, is a Marine Protected Area (MPA) where, unlike no-take areas, artisanal fishing has been permitted (except trawling), owing to social and economic pressures. Nevertheless, restrictions on artisanal fishing have increased through a fishing charter (1999). In the meantime, recreational fishing was progressively banned, which has helped as a management tool to make the restrictions on artisanal fishing acceptable in social terms. Monitoring of the artisanal fishing (2000–2005) reveals the stability of the fishing fleet (9–13 vessels); of the fishing effort [number of fishing sets per day between 3.4 (±2.1) and 6.9 (±3.4) in spring, and 3.0 (±1.7) and 5.2 (±2.7) in summer]; and of yields [catch per unit effort between 1.27 (±0.72) and 1.68 (±1.44) kg 100 m of net−1 d−1]. Furthermore, based on an analysis of available data, artisanal fishing does not jeopardize the conservation objectives of the MPA, so that, from 1963 to date, the issue has changed from “What can be done to ban commercial fishing?” to “Is there any reason to ban commercial fishing?”.

From December 2003, for the first time, people looking for work and those in jobs or training will have a right to complain about discriminatory behaviour based on their sexual orientation and religion or religious belief. Similar protection against discrimination based on age should also some into force in 2006. It seems clear that these regulations represent a significant step forward in addressing unfair discrimination in the UK and in achieving a certain level of uniformity and coherence across discrimination legislation.

The current trend toward corporate acquisitions of CPA firms poses potential threats to the autonomy and ethical standards of public accounting professionals. This recent consolidation movement suggests that for the first time a significant number of public accounting professionals are subject to the supervision and control of nonprofessionals. In addition to acknowledging the potential threats to auditor independence and objectivity, this paper suggests that these new organizational arrangements for the provision of public accounting services have other negative effects on professionalism and ethics such as desensitizing CPAs to traditional professional values, and subverting professional institutions to the goals of corporate employers. This paper develops a framework that identifies several specific research questions related to the effects of corporate ownership on professionalism and ethics in public accounting.

In January 2021 the UK government granted an application for authorisation to use thiamethoxam, a neonicotinoid pesticide, to protect commercial sugar beet crops from attack by viruses transmitted by aphids. This was the first time such an authorisation had been granted in the United Kingdom (UK) and there were concerns that it signalled a weakening of environmental standards now that the UK was no longer part of the European Union. In fact, similar authorisations had been granted by several European Member States in the last 2 years, despite the ban on the use of neonicotinoids introduced in 2018. Nevertheless, the reasons for granting the authorisation do suggest that the balance between adopting a precautionary approach to environmental protection and taking emergency action to protect economic interests may have shifted. It was acknowledged that the proposed mitigation to safeguard bees and other wildlife was not entirely satisfactory. In the end, due to unforeseen weather conditions it meant that the pesticide is not necessary, which in itself demonstrates that short-term emergency measures are unsuitable for dealing with the problem. If the sugar beet industry is to continue to prosper in the UK, it will need to be managed in a way that provides resistance to virus infection without the use of controversial chemicals.

Bottom longline hook and trap fishing gear can potentially damage sensitive benthic areas (SBAs) in the ocean; however, the large-scale risks to these habitats are poorly understood because of the difficulties in mapping SBAs and in measuring the bottom-contact area of longline gear. In this paper, we describe a collaborative academic–industry–government approach to obtaining direct presence–absence data for SBAs and to measuring gear interactions with seafloor habitats via a novel deepwater trap camera and motion-sensing systems on commercial longline traps for sablefish (Anoplopoma fimbria) within SGaan Kinghlas – Bowie Seamount Marine Protected Area. We obtained direct presence–absence observations of cold-water corals (Alcyonacea, Antipatharia, Pennatulacea, Stylasteridae) and sponges (Hexactinellida, Demospongiae) at 92 locations over three commercial fishing trips. Video, accelerometer, and depth sensor data were used to estimate a mean bottom footprint of 53 m2 for a standard sablefish trap, which translates to 3200 m2 (95% CI = 2400–3900 m2) for a 60-trap commercial sablefish longline set. Our successful collaboration demonstrates how research partnerships with commercial fisheries have potential for massive improvements in the quantity and quality of data needed for conducting SBA risk assessments over large spatial and temporal scales.

Abstract Halliburton Company v Chubb Bermuda Insurance Ltd (formerly known as Ace Bermuda Insurance Ltd [2020] UKSC 48 is an important case not only to the UK but also to the international arbitration community for several reasons: first, it examines indispensable duties in international arbitration and for the first time recognises and explicates upon the duty of disclosure at the highest court of the United Kingdom; secondly, it addresses and clarifies key concepts in international arbitration; thirdly, it confirms the objective nature of the test of justifiable doubts which has wider implications for other arbitral forums; fourthly, it illustrates how the duties of impartiality, disclosure, and confidentiality interact with and affect each other and how the key concepts should be applied to this interaction; and finally, it lays down useful guidance for arbitrators. For these reasons, this case deserves close and careful examination. This article aims to explain the significance of the aforesaid and suggests that, in addition to what has been addressed, further judicial explanations are warranted in what other aspects.

Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) enables temporary haemorrhage control and physiological stabilisation. This article describes the bespoke Defence Medical Services (DMS) training package for effectively using REBOA. The article covers how the course was designed, how the key learning objectives are taught, participant feedback and the authors’ perceptions of future training challenges and opportunities. Since the inaugural training course in April 2019, the authors have delivered six courses, training over 100 clinicians. For the first time in the UK DMS, we designed and delivered a robust specialist endovascular training programme, with demonstrable, significant increases in confidence and competence. As a result of this course, the first DMS REBOA-equipped forward surgical teams deployed in June 2019. Looking to the future, there is a requirement to develop an assessment of skill retention and the potential need for revalidation.

Purpose – The aim of this article is to investigate the organization of water cooperatives in Greece for the first time, as promoted by a spontaneous social mobilization called Initiative 136. The above attempt appears as an alternative proposition as opposed to the state-driven full privatization of EYATH S.A. Design/methodology/approach – This article presents previous work on water cooperatives and the negative effects of water privatization worldwide, relating it to water privatization in Greek reality through the prism of the current recession. Findings – While full privatization under the pressure of the economic crisis is very likely to yield significantly negative results, a transformation into a water cooperative might provide a viable solution. Research limitations/implications – Water cooperatives provide a solution for water distribution that is friendly for the consumer, the society and the environment. Practical implications – Application of a cooperative method of water provision in Greece could be a springboard for the use of the model in other areas. Originality/value – The article evaluates the privatization and cooperativization attempt of EYATH S.A. based on previous related research and considering Greece ' s current conditions.

A Current

Purpose – The purpose of this paper is to address issues of medical leadership within health systems and to clarify the associated conceptual issues, for example, leadership versus management and medical versus clinical leadership. However, its principle contribution is to raise the issue of the purpose or outcome of medical leadership, and, in this respect, it argues that it is to promote medical engagement. Design/methodology/approach – The approach is to provide evidence, both from the literature and empirically, to suggest that enhanced medical engagement leads to improved organisational performance and, in doing so, to review the associated concepts. Findings – Building on current evidence from the UK and Australia, the authors strengthen previous findings that effective medical leadership underpins the effective organisational performance. Research limitations/implications – There is a current imbalance between the size of the databases on medical engagement between the UK (very large) and Australia (small but developing). Practical implications – The authors aim to equip medical leaders with the appropriate skill set to promote and enhance greater medical engagement. The focus of leaders in organisations should be in creating a culture that fosters and supports medical engagement. Social implications – This paper provides empowerment of medical professionals to have greater influence in the running of the organisation in which they deliver care. Originality/value – The paper contains, for the first time, linked performance data from the Care Quality Commission in the UK and from Australia with the new set of medical engagement findings.
