The role of sustainable events in the management of historic buildings

As the use of historic building as venues for commercial activity grows, events management professionals working in historic buildings are faced with a number of sustainability challenges, including conservation, preservation, social value and financial sustainability, as well as with satisfying their clients. In particular, these professionals are required to maintain the complex balance between the competing priorities of historic value and contemporary relevance. Little research has thus far investigated the role that sustainable events can play in the management of historic buildings, beyond considerations of the trade-off between conservation and income generation. This research analyses the contribution that events can make to the sustainable management of historic buildings, with an emphasis on understanding the perspectives of event managers within these properties, based on qualitative interviews with historic building event managers and stakeholders in London, United Kingdom. A key finding of the research is that event managers within historic buildings have complex views of sustainability that are specific to these properties and which are not captured in the mainstream events management literature. The paper contributes to the emerging literature on sustainable events and also develops earlier research on the role of events and other income-generating activities in historic buildings

Berries as a case study for crop wild relative conservation, use, and public engagement in Canada

Conservation of plant biodiversity, in particular crop wild relatives including those tended and cultivated by Indigenous Peoples, is critical to food security and agricul ture. Building on the 2019 road map for crop wild relatives, we examine berries as a case study for crop wild relative conservation, use, and public engagement. We focus on berries due not only to their economic, cultural, and nutritional importance but also because they are consumed fresh, providing a unique opportunity for individuals and communities to connect with plants. We outline health benefits, geographic dis tribution, and species at risk for Canadian berries. We describe practices, strategies, and approaches used by Indigenous Peoples to steward berries and emphasize the importance of traditional knowledge. We highlight opportunities for in situ and ex situ berry conservation and use of berries in plant breeding and Indigenous foodways. Our aim is to lay the groundwork for future collaborative efforts in these areas and to showcase berries as a useful case study for conservation of food plant biodiversity and public engagement

Extended-release pharmacotherapy for opioid use disorder (EXPO):protocol for an open-label randomised controlled trial of the effectiveness and cost-effectiveness of injectable buprenorphine versus sublingual tablet buprenorphine and oral liquid methadone

BACKGROUND: Sublingual tablet buprenorphine (BUP-SL) and oral liquid methadone (MET) are the daily, standard-of-care (SOC) opioid agonist treatment medications for opioid use disorder (OUD). A sizable proportion of the OUD treatment population is not exposed to sufficient treatment to attain the desired clinical benefit. Two promising therapeutic technologies address this deficit: long-acting injectable buprenorphine and personalised psychosocial interventions (PSI). This study will determine (A) the effectiveness and cost-effectiveness — monthly injectable, extended-release (BUP-XR) in a head-to-head comparison with BUP-SL and MET, and (B) the effectiveness of BUP-XR with adjunctive PSI versus BUP-SL and MET with PSI. Safety, retention, craving, substance use, quality-adjusted life years, social functioning, and subjective recovery from OUD will be also evaluated. METHODS: This is a pragmatic, multi-centre, open-label, parallel-group, superiority RCT, with a qualitative (mixed-methods) evaluation. The study population is adults. The setting is five National Health Service community treatment centres in England and Scotland. At each centre, participants will be randomly allocated (1:1) to BUP-XR or SOC. At the London study co-ordinating centre, there will also be allocation of participants to BUP-XR with PSI or SOC with PSI. With 24 weeks of study treatment, the primary outcome is days of abstinence from non-medical opioids during study weeks 2–24 combined with up to 12 urine drug screen tests for opioids. For 90% power (alpha, 5%; 15% inflation for attrition), 304 participants are needed for the BUP-XR versus SOC comparison. With the same planning parameters, 300 participants are needed for the BUP-XR and PSI versus SOC and PSI comparison. Statistical and health economic analysis plans will be published before data-lock on the Open Science Framework. Findings will be reported in accordance with the Consolidated Standards of Reporting Trials and Consolidated Health Economic Evaluation Reporting Standards. DISCUSSION: This pragmatic randomised controlled trial is the first evaluation of injectable BUP-XR versus the SOC medications BUP-SL and MET, with personalised PSI. If there is evidence for the superiority of BUP-XR over SOC medication, study findings will have substantial implications for OUD clinical practice and treatment policy in the UK and elsewhere.

Molecular Pnictogen Activation by Rare Earth and Actinide Complexes

This review covers the activation of molecular pnictogens (group 15 elements) by homogeneous rare earth and actinide complexes. All examples of molecular pnictogen activation (dinitrogen, white phosphorus, yellow arsenic) by both rare earths and actinides, to date (2015), are discussed, focusing on synthetic methodology and the structure and bonding of the resulting complexes

Techniques in the prevention and management of seromas after breast surgery

ABSTRACT:  Seromas are the most frequent complications following breast surgery, resulting in significant discomfort and morbidity with possible delays in commencing adjuvant therapies. Varied clinical practices exist in the techniques employed to prevent and manage seromata. This article assesses published literature on the techniques employed in prevention of seroma formation following breast surgery, evaluating the different methodologies used. Although prevention is the best strategy, seromata remain problematic and we consider their management. The principle findings were that prevention is key to the management of seromata. Methods employed to prevent seromata include suction drainage, shoulder immobilization, quilting sutures, fibrin sealants and innovative measures of managing the axilla, among others. The evidence demonstrated that a combination of quilting and drains significantly reduces the incidence and volumes of seromata. These effects are sustained by minimizing use of electrocautery, alongside increasing frequencies of axillary sentinel lymph node biopsies and node sampling. The efficacy data on fibrin sealants is inconclusive and consequently should not be routinely used alone or accompanied by quilting sutures. Clinically significant seromas deemed ’symptomatic’ by patients and complicating infected seromas should be aspirated. There are limited data on the recommended treatment of established seromas with a paucity of high-quality studies and further research involving randomized trials are indicated. </jats:p

Dynamics of herbicide transport and partitioning under event flow conditions in the lower Burdekin region, Australia

This study examined the temporal variability in herbicide delivery to the Great Barrier Reef (GBR) lagoon (Australia) from one of the GBR catchment's major sugarcane growing regions. Annual loads of measured herbicides were consistently in the order of 200+ kg. Atrazine, it's degradate desethylatrazine, and diuron contributed approximately 90% of annual herbicide load, with early 'first-flush' events accounting for the majority of herbicide loads leaving the catchment. Assessment of herbicide water–sediment partitioning in flood runoff highlighted the majority of herbicides were transported in predominantly dissolved form, although a considerable fraction of diuron was transported in particulate-bound form (ca. 33%). Diuron was also the herbicide demonstrating the highest concentrations and frequency of detection in sediments collected from catchment waterways and adjacent estuarine–marine environments, an outcome aligning with previous research. Herbicide physico-chemical properties appear to play a crucial role in partitioning between water column and sediment habitat types in GBR receiving ecosystems

Bulky 4-phosphacyclohexanones: diastereoselective complexations, orthometallations and unprecedented [3.1.1]metallabicycles

The 4-phosphacyclohexanones, 2,2,6,6-tetramethyl-1-phenyl-4-phosphorinanone (La), 1,2,6-triphenyl-4-phosphorinanone (PhLb), 1-cyclohexyl-2,6-diphenyl-4-phosphorinanone (CyLb) and 1-tert-butyl-2,6-diphenyl-4-phosphorinanone (BuLb) have been made by modifications of literature methods. Phosphines RLb are each formed as mixtures of meso- and rac-diastereoisomers. Isomerically pure rac-PhLb, rac-CyLb and meso-BuLb can be isolated by recrystallisation from MeCN. Heating mixtures of isomers of RLb with TsOH leads to isomerisations to give predominantly the meso-RLb. The complex trans-[PdCl2(La)2] (1) is readily made from [PdCl2(NCPh)2] but the analogous platinum complex 2 has not been detected and instead, cyclometallation at the 3-position (α to the ketone) in the phosphacycle occurs to give trans-[PtCl(La)(La–3H)] (3) (where La–3H = La deprotonated at the 3-position) featuring a [3.1.1]metallabicycle as confirmed by X-ray crystallography. The analogous palladabicycle 4 has been detected upon treatment of 1 with Et3N in refluxing toluene. The type of complex formed by RLb depends on which diastereoisomer (meso or rac) is involved. rac-PhLb (a mixture of R,R- and S,S-enantiomers, labelled α and β) forms trans-[MCl2(rac-PhLb)2], M = Pd (5) or Pt (6), as mixtures of diastereoisomers (αα/ββ and αβ forms). The structure of αα-6 has been determined by X-ray crystallography. Ligand competition experiments monitored by 31P NMR showed that Pd(II) and Pt(II) have a significant preference to bind rac-PhLb over meso-PhLb. meso-BuLb reacts with [PtCl2(NCBut)2] under ambient conditions to give the binuclear complex [Pt2Cl2(meso-BuLb-2′H)2] (7) where orthometallation has occurred on one of the exocyclic phenyl substituents as confirmed by X-ray crystallography. rac-BuLb reacts with [PtCl2(NCBut)2] to give a mononuclear cyclometallated species assigned the structure trans-[PtCl(rac-BuLb-2′H)(BuLb)] (8) on the basis of its 31P NMR spectrum. rac-CyLb reacts with [PtCl2(NCBut)2] in refluxing toluene to give trans-[PtCl2(rac-CyLb)2] (9) and the crystal structure of αβ-9 has been determined

Data Ethics Club: creating a collaborative space to discuss data ethics

Awareness and management of ethical issues in data science is becoming increasingly relevant to us all, and a crucial skill for data scientists. Discussion of contemporary issues in collaborative and interdisciplinary spaces is an engaging way to allow data science work to be influenced by those with expertise in philosophy, history, sociology and beyond, and so improve the ability of data scientists to think critically about the ethics of their work. However, opportunities to do so are limited. Data Ethics Club (based at dataethicsclub.com) is a fortnightly discussion group about data science and ethics, whose community-generated resources are hosted in an open online repository. This repository includes a list of data science and ethics materials around multiple topics of interest, alongside processes and templates for leading an online data ethics discussion group. These meetings and materials are designed to reduce the barrier to learning, reflection and critique on data science and ethics for all interested parties, with the broader aim of building ethics into the cultural fabric of quality data science work
