    Donastorg, Angelines; Renukappa, Suresh; Suresh, Subashini (Emerald, 2021-12-31)
    Purpose Currently, Renewable Energy (RE) sources represent a crucial pillar in obtaining sustainable development, one of the global goals for all countries. However, this presents a unique challenge for emerging and developing countries. Since, the technical and financial issues remain a significant barrier in implementing RE projects several mechanisms are available to aid the financial aspect of investing and implementing clean energy projects. This paper discusses new and traditional trends in the financial area of renewable investment, focusing on the Dominican Republic (DR), identifying the gaps in the financial area regarding RE. Design/methodology/approach An empirical study was conducted in the Dominican Republic. This country is located at the heart of the Caribbean. Given the complexity of RE and developing countries issues and the scarcity of comparable research in the area, an interpretivist research paradigm along with the qualitative methodology was adopted. Primary data was collected through semi-structured interviews. The study sample includes: Directors, Chief Executive Officers (CEOs) and Managers responsible for the implementation of RE strategies in their respective departments/organisations. NVivo software was used for data management and the collected data was analysed using content analysis. Findings The research highlighted several severe financial handicaps regarding RE in the DR: The lack of RE assets recognition; Lack of RE investment loans; Perceived RE risk; and Lack of financial guarantor. After extensive interviews with critical actors in the RE sector in the DR, the possible solutions and recommendations for avoiding locking the energy and economic sector in fossil fuel debt, are: (a) diversification of RE technology assets recognition (b) implementation of government RE fund (c) RE education on all actors (d) introduction and adoption of new financial trends such as: green bonds, bank pooling, cooperatives and more. Originality/value This paper provides information and knowledge related to financial tools and policies that are available for the RE projects in the DR. The results have a socio-economic impact. This research provides a better understanding of the key financial tools to be explored by RE project developers in the developing countries. This study shows the gaps that exist between the knowledge that the stakeholders should possess and the actual knowledge that exists in the country regarding the financial aspect of an RE project.
  • Assessing off-site readiness in construction organisations cases from India

    Rana, Muhammad; Arif, Mohammed; Kaushik, Amit; Bendi, Deepthi; Sawhney, Anil (Emerald, 2021-12-31)
    Purpose This paper intends to present factors affecting the Indian construction organisations in adopting Off-Site Construction (OSC) methods. Design/Methodology/Approach An existing readiness maturity model has been used to assess three large organisations in different parts of India. A case study methodology has been adopted in this paper to highlight critical issues in OSC adoption in India. Findings This paper presents three case studies and concludes the Indian construction sectors readiness to adopt the OSC methods. Through the case studies, different issues related to the adoption of OSC have been identified and highlighted for the Indian construction sector. Although the three companies are large, there are several Small and Medium-sized Enterprises’ (SME) operating in India's construction sector, and future research shall be needed to review these SMEs. Originality/Value Through the three case studies, several factors related to the implementation of OSC methods have been identified and highlighted within the Indian construction sector. Although the model has been applied to the Indian construction sector, it can easily be modified to fit into other areas and similar dynamics and business conditions. Practical Implications The proposed OSC readiness maturity model guides construction practitioners in India through a structured process to assess their OSC readiness in the market. This assessment enables them to evaluate and benchmark their processes through the strategic and operational phases. This research will add to the existing knowledge of OSC in India by mapping issues relevant to India's construction industry. The research has provided background on the status of OSC, the drivers and barriers affecting the implementation of Off-site Construction techniques in the Indian construction industry. Limitations: This research study is broadly focused on developing and assessing an off-site construction readiness framework for Indian construction organisations. The research scope and the population for data collection are limited to Large construction organisations in India only.
  • Analysis of laboratory blood parameter results for patients diagnosed with COVID‐19, from all ethnic group populations: A single centre study

    Marwah, Mandeep; Marwah, Sukhjinder; Blann, Andrew; Morrissey, Hana; Ball, Patrick; Wandroo, Farooq A (Wiley, 2021-05-03)
    Introduction Although factors such as age, sex, diabetes, obesity and changes in certain laboratory investigations are important prognostic factors in COVID‐19 infection, these may not apply to all ethnic/racial groups. We hypothesized differences in routine biochemistry and haematology indices in Caucasian and a combined group of Black, Asian and Minority Ethnic (BAME) patients who tested positive for COVID‐19 who died, compared to survivors. Methods We tested our hypothesis in 445 patients (229 Caucasian, 216 BAME) admitted to secondary care with proven COVID‐19 infection, in whom standard routine laboratory indices were collected on admission. Results After 28 weeks, 190 (42.7%) had died within 28 days of COVID diagnosis (97 Caucasians [42.4%], 93 BAMEs [43.1%], P = .923). A general linear model analysis found the ethnicity interaction with mortality to be significant for fibrinogen, ferritin and HbA1c (after controlling for age). In a multivariate analysis, a neutrophil/lymphocyte ratio > 7.4 and a urea/albumin ratio > 0.28 increased the odds of death for both the Caucasian and the BAME group. Additional factors increasing the odds ratio in the BAME group included age >60 years and being diabetic. Conclusion Neutrophil/lymphocyte ratio and urea/albumin ratio are simple metrics that predict death to aid clinicians in determining the prognosis of COVID‐19 and help provide early intensive intervention to reduce mortality. In the BAME groups, intensive monitoring even at younger age and those with diabetes may also help reduce COVID‐19 associated mortality.
  • Supplemental and settlement agreements in the performance of construction contracts and their implications for subsequent adjudications

    Ndekugri, Issaka (Sweet and Maxwell, 2021-12-31)
    Parties to construction contracts constantly negotiate a myriad of matters concerning their existing contracts. Examples include: variation of an existing contract; additional works as a separate contract; call off contracts under framework agreements; settlement of existing claims; and amicable settlement of disputes. Such negotiation options may lead to a scenario of multiple contracts between the parties under which disputes may arise. This paper critically examines the issues associated with adjudication in such a multi contract scenario and how they have been decided by the court. It is hoped that, by providing in one place understanding of the range of solutions in the most commonly encountered factual contexts, it will be a useful reference for parties to construction contracts, their advisers and adjudicators.
  • Business model innovation (BMI) in small enterprises from developing countries during COVID-19 outbreak: Exploring drivers and BMI outcomes

    Martinez, Gabriel; Renukappa, Suresh; Suresh, Subashini (Inderscience Enterprises Ltd., 2021-12-31)
    The purpose of this paper is to provide understanding of driving forces for Business Model Innovation (BMI) during the pandemic for small businesses in developing countries, comparing them with identified BMI drivers before the outbreak and evaluating their response to the current crisis. A qualitative multiple case study is conducted as it allows the study of BMI within real life and contemporary context. Case study organisations that adopt innovative business models participated from technology, education, and social enterprises. Findings shows that small organisations are influenced by internal and external factors towards BMI during the pandemic. Case organisations showed resilience to the crisis by adjusting accordingly to allow uninterrupted operation during lockdown; developing new products, services and processes that would ensure sustained demand during COVID-19 pandemic. The study explores theoretical implications of the findings. Also, lessons from this research could be useful for practitioners from developed and developing countries. Policymakers from developing countries could benefit from focusing their activities on promoting firms to find novel ways of operating during times of pandemic preventing further economic damage and unemployment.
  • N-Carbamate protected amino acid derived guanidine organocatalysts

    Al-Taie, Zahraa S; Anderson, Joseph M; Bischoff, Laura; Christensen, Jeppe; Coles, Simon J; Froom, Richard; Gibbard, Mari E; Jones, Leigh F; de Kleijne, FFJ; Murphy, Patrick J; et al. (Elsevier, 2021-04-02)
    We report the preparation of a range of N-protected amino acid derived guanidine organocatalysts and their application to the Michael addition of 2-hydroxy-1,4-napthoquinone to β-nitrostyrene, achieving a maximum ee of 26%. Whilst these catalysts gave poor ees, the structural variation together with the X-ray crystallographic study of the intra- and intermolecular hydrogen bonding reported suggest that the C2-symmetric catalyst are lead compounds for the further development of this methodology.
  • Critical barriers to environmental management system implementation in the Nigerian construction industry

    Ojo, Lekan; Oladinrin, Olugbenga; Obi, Lovelin (Springer, 2021-04-23)
    The impact of different hazardous substances of the construction industry being released to the environment is alarming. This constitutes an adverse effect on the quality of life of construction workers and the populace at large. To reduce this menace, Environmental Management System (EMS) was put in place. Meanwhile, the implementation of EMS in the Nigerian construction industry (NCI) is not certain. This study, therefore, investigated the barriers to EMS implementation in the NCI to group them into a smaller form, i.e., fewer numbers. A questionnaire survey was developed and administered to construction professionals in Nigeria using a purposive sampling technique. The retrieved 106 copies of the questionnaires were subjected to both descriptive and inferential statistics such as mean score, standard deviation, analysis of variance test, post hoc test and exploratory factor analysis. An exploratory factor analysis was conducted three times to identify the critical barriers to EMS implementation in the NCI. The study findings reveal three main categories of barriers affecting EMS implementation, namely; (1) knowledge barrier; (2) process barrier; and (3) culture and management barrier. The study concluded that the three factors indicate the major cardinal barriers that could describe the impediment of EMS in the NCI. It was recommended that the training of construction professionals is important to enhance improvement culture in the NCI.
  • Modulation of Protein phosphatase 1 complexes: a promising approach in cancer treatment

    Matos, Barbara; Howl, John; Jeronimo, Carmen; Fardilha, Margarida (Elsevier, 2021-12-31)
    Cancer is the second leading cause of death worldwide. Despite the numerous therapeutic options available, tumor heterogeneity and chemoresistance have limited their success and the development of an effective anticancer therapy remains a major challenge in oncology research. The serine/threonine-protein phosphatase 1 (PP1) and its complexes have been recognized as potential drug targets. Although research on the modulation of PP1 complexes is currently at an early stage, there is an immense potential. Chemically diverse compounds have been developed to disrupt or stabilize different PP1 complexes in various cancer types with the objective to inhibit disease progression. Beneficial results obtained in vitro now require further pre-clinical and clinical validation. In conclusion, the modulation of PP1 complexes seems to be a promising, albeit challenging, therapeutic strategy for cancer.

  • Confronting taxonomic vandalism in biology: conscientious community self-organization can preserve nomenclatural stability

    Wüster, Wolfgang; Thomson, Scott A; O'Shea MBE, Mark; Kaiser, Hinrich (Oxford University Press, 2021-04-20)
    Self-published taxon descriptions, bereft of a basis of evidence, are a long-standing problem in taxonomy. The problem derives in part from the Principle of Priority in the International Code of Zoological Nomenclature, which forces the use of the oldest available nomen irrespective of scientific merit. This provides a route to ‘immortality’ for unscrupulous individuals through the mass-naming of taxa without scientific basis, a phenomenon referred to as taxonomic vandalism. Following a flood of unscientific taxon namings, in 2013 a group of concerned herpetologists organized a widely supported, community-based campaign to treat these nomina as lying outside the permanent scientific record, and to ignore and overwrite them as appropriate. Here, we review the impact of these proposals over the past 8 years. We identified 59 instances of unscientific names being set aside and overwritten with science-based names (here termed aspidonyms), and 1087 uses of these aspidonyms, compared to one instance of preference for the overwritten names. This shows that when there is widespread consultation and agreement across affected research communities, setting aside certain provisions of the Code can constitute an effective last resort defence against taxonomic vandalism and enhance the universality and stability of the scientific nomenclature.
  • The UPTAKE study: implications for the future of COVID-19 vaccination trial recruitment in UK and beyond

    Sethi, Sonika; Kumar, Aditi; Mandal, Anandadeep; Shaikh, Mohammed; Hall, Claire A; Kirk, Jeremy MW; Moss, Paul; Brookes, Matthew J; Basu, Supratik (Springer Science and Business Media LLC, 2021-04-20)
    Background Developing a safe and effective vaccine will be the principal way of controlling the COVID-19 pandemic. However, current COVID-19 vaccination trials are not adequately representing a diverse participant population in terms of age, ethnicity and comorbidities. Achieving the representative recruitment targets that are adequately powered to the study remains one of the greatest challenges in clinical trial management. To ensure accuracy and generalisability of the safety and efficacy conclusions generated by clinical trials, it is crucial to recruit patient cohorts as representative as possible of the future target population. Missing these targets can lead to reduced validity of the study results and can often slow down drug development leading to costly delays. Objective This study explores the key factors related to perceptions and participation in vaccination trials. Methods This study involved an anonymous cross-sectional online survey circulated across the UK. Statistical analysis was done in six phases. Multi-nominal logistic models examined demographic and geographic factors that may impact vaccine uptake. Results The survey had 4884 participants of which 9.44% were Black Asian Minority Ethnic (BAME). Overall, 2020 (41.4%) respondents were interested in participating in vaccine trials; 27.6% of the respondents were not interested and 31.1% were unsure. The most interested groups were male (OR = 1.29), graduates (OR = 1.28), the 40–49 and 50–59 age groups (OR = 1.88 and OR = 1.46 respectively) and those with no health issues (OR = 1.06). The least interested groups were BAME (OR = 0.43), those from villages and small towns (OR = 0.66 and 0.54 respectively) and those aged 70 and above (OR = 1.11). Conclusions In order to have a vaccination that is generalisable to the entire population, greater work needs to be done in engaging a diverse cohort of participants. Public health campaigns need to be targeted in improving trial recruitment rates for the elderly, BAME community and the less educated rural population.
  • Assessment, endoscopy, and treatment in patients with acute severe ulcerative colitis during the COVID-19 pandemic (PROTECT-ASUC): a multicentre, observational, case-control study

    Sebastian, Shaji; Walker, Gareth J; Kennedy, Nicholas A; Conley, Thomas E; Patel, Kamal V; Subramanian, Sreedhar; Kent, Alexandra J; Segal, Jonathan P; Brookes, Matthew J; Bhala, Neeraj; et al. (Elsevier, 2021-02-02)
    Background There is a paucity of evidence to support safe and effective management of patients with acute severe ulcerative colitis during the COVID-19 pandemic. We sought to identify alterations to established conventional evidence-based management of acute severe ulcerative colitis during the early COVID-19 pandemic, the effect on outcomes, and any associations with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and severe COVID-19 outcomes. Methods The PROTECT-ASUC study was a multicentre, observational, case-control study in 60 acute secondary care hospitals throughout the UK. We included adults (≥18 years) with either ulcerative colitis or inflammatory bowel disease unclassified, who presented with acute severe ulcerative colitis and fulfilled the Truelove and Witts criteria. Cases and controls were identified as either admitted or managed in emergency ambulatory care settings between March 1, 2020, and June 30, 2020 (COVID-19 pandemic period cohort), or between Jan 1, 2019, and June 30, 2019 (historical control cohort), respectively. The primary outcome was the proportion of patients with acute severe ulcerative colitis receiving rescue therapy (including primary induction) or colectomy. The study is registered with, NCT04411784. Findings We included 782 patients (398 in the pandemic period cohort and 384 in the historical control cohort) who met the Truelove and Witts criteria for acute severe ulcerative colitis. The proportion of patients receiving rescue therapy (including primary induction) or surgery was higher during the pandemic period than in the historical period (217 [55%] of 393 patients vs 159 [42%] of 380 patients; p=0·00024) and the time to rescue therapy was shorter in the pandemic cohort than in the historical cohort (p=0·0026). This difference was driven by a greater use of rescue and primary induction therapies with biologicals, ciclosporin, or tofacitinib in the COVID-19 pandemic period cohort than in the historical control period cohort (177 [46%] of 387 patients in the COVID-19 cohort vs 134 [36%] of 373 patients in the historical cohort; p=0·0064). During the pandemic, more patients received ambulatory (outpatient) intravenous steroids (51 [13%] of 385 patients vs 19 [5%] of 360 patients; p=0·00023). Fewer patients received thiopurines (29 [7%] of 398 patients vs 46 [12%] of 384; p=0·029) and 5-aminosalicylic acids (67 [17%] of 398 patients vs 98 [26%] of 384; p=0·0037) during the pandemic than in the historical control period. Colectomy rates were similar between the pandemic and historical control groups (64 [16%] of 389 vs 50 [13%] of 375; p=0·26); however, laparoscopic surgery was less frequently performed during the pandemic period (34 [53%] of 64] vs 38 [76%] of 50; p=0·018). Five (2%) of 253 patients tested positive for SARS-CoV-2 during hospital treatment. Two (2%) of 103 patients re-tested for SARS-CoV-2 during the 3-month follow-up were positive 5 days and 12 days, respectively, after discharge from index admission. Both recovered without serious outcomes. Interpretation The COVID-19 pandemic altered practice patterns of gastroenterologists and colorectal surgeons in the management of acute severe ulcerative colitis but was associated with similar outcomes to a historical cohort. Despite continued use of high-dose corticosteroids and biologicals, the incidence of COVID-19 within 3 months was low and not associated with adverse COVID-19 outcomes.
  • Pseudomonas aeruginosa infection in augmented care: the molecular ecology and transmission dynamics in four large UK hospitals

    Halstead, FD; Quick, J; Niebel, M; Garvey, M; Cumley, N; Smith, R; Neal, T; Roberts, P; Hardy, K; Shabir, S; et al. (Elsevier, 2021-01-31)
    Background Pseudomonas aeruginosa is a common opportunistic pathogen and molecular typing in outbreaks has linked patient acquisition to contaminated hospital water systems. Aim To elucidate the role of P. aeruginosa transmission rates in non-outbreak augmented care settings in the UK. Methods Over a 16-week period, all water outlets in augmented care units of four hospitals were sampled for P. aeruginosa and clinical isolates were collected. Outlet and clinical P. aeruginosa isolates underwent whole-genome sequencing (WGS), which with epidemiological data identified acquisition from water as definite (level 1), probable (level 2), possible (level 3), and no evidence (level 4). Findings Outlets were positive in each hospital on all three occasions: W (16%), X (2.5%), Y (0.9%) and Z (2%); and there were 51 persistently positive outlets in total. WGS identified likely transmission (at levels 1, 2 and 3) from outlets to patients in three hospitals for P. aeruginosa positive patients: W (63%), X (54.5%) and Z (26%). According to the criteria (intimate epidemiological link and no phylogenetic distance), approximately 5% of patients in the study ‘definitely’ acquired their P. aeruginosa from their water outlets in the intensive care unit. This study found extensive evidence of transmission from the outlet to the patients particularly in the newest hospital (W), which had the highest rate of positive outlets. Conclusions The overall findings suggest that water outlets are the most likely source of P. aeruginosa nosocomial infections in some settings, and that widespread introduction of control measures would have a substantial impact on infections.
  • Phase Transformation Dynamics in Sulfate-Loaded Lanthanide Triphosphonates. Proton Conductivity and Application as Fillers in PEMFCs.

    Salcedo, Inés R.; Colodrero, Rosario MP; Bazaga-García, Montse; López-González, M; Del Río, Carmen; Xanthopoulos, Konstantinos; Demadis, Konstantinos D.; Hix, Gary B.; Furasova, Aleksandra D; Choquesillo-Lazarte, Duane; et al. (American Chemical Society (ACS), 2021-03-25)
    Phase transformation dynamics and proton conduction properties are reported for cationic layer-featured coordination polymers derived from the combination of lanthanide ions (Ln3+) with nitrilo-tris(methylenephosphonic acid) (H6NMP) in the presence of sulfate ions. Two families of materials are isolated and structurally characterized, i.e., [Ln2(H4NMP)2(H2O)4](HSO4)2·nH2O (Ln = Pr, Nd, Sm, Eu, Gd, Tb, Er, Yb; n = 4–5, Series I) and [Ln(H5NMP)]SO4·2H2O (Ln = Pr, Nd, Eu, Gd, Tb; Series II). Eu/Tb bimetallic solid solutions are also prepared for photoluminescence studies. Members of families I and II display high proton conductivity (10–3 and 10–2 S·cm–1 at 80 °C and 95% relative humidity) and are studied as fillers for Nafion-based composite membranes in PEMFCs, under operating conditions. Composite membranes exhibit higher power and current densities than the pristine Nafion membrane working in the range of 70–90 °C and 100% relative humidity and with similar proton conductivity.
  • Domestic researchers with longer careers generate higher average citation impact but it does not increase over time

    Maflahi, Nabeil; Thelwall, Michael (MIT Press, 2021-04-23)
    Information about the relative strengths of scholars is needed for the efficient running of knowledge systems. Since academic research requires many skills, more experienced researchers might produce better research and attract more citations. This article assesses career citation impact changes 2001-2016 for domestic researchers (definition: first and last Scopus journal article in the same country) from the twelve nations with most Scopus documents. Careers are analysed longitudinally, so that changes are not due to personnel evolution, such as researchers leaving or entering a country. The results show that long term domestic researchers do not tend to improve their citation impact over time but tend to achieve their average citation impact by their first or second Scopus journal article. In some countries, this citation impact subsequently declines. These longer-term domestic researchers have higher citation impact than the national average in all countries, however, whereas scholars publishing only one journal article have substantially lower citation impact in all countries. The results are consistent with an efficiently functioning researcher selection system but cast slight doubt on the long-term citation impact potential of long-term domestic researchers. Research and funding policies may need to accommodate these patterns when citation impact is a relevant indicator.
  • Is research with qualitative data more prevalent and impactful now? Interviews, case studies, focus groups and ethnographies

    Thelwall, Michael; Nevill, Tamara (Elsevier, 2021-12-31)
    Researchers, editors, educators, librarians, and publishers need to understand the mix of research methods used in their field to guide decision making, with qualitative research apparently threatened by big data. In response, this study assesses the prevalence and citation impact of academic research 1996-2019 that reports one of four common methods to gather qualitative data: interviews; focus groups; case studies; ethnography. With minor exceptions, the prevalence of qualitative data has increased, often substantially, since 1996. In addition, all 27 broad fields (as classified by Scopus) now publish some qualitative research, with interviewing being by far the most common approach. The citation impact of interview and focus group research mostly decreased over time, whereas of case study citation impact increased, and ethnography was above average in its two core subject areas. This suggests that methods teachers, researchers, editors, librarians, and publishers should be increasingly open to the value of qualitative data.
  • New working practices: a scientometric review

    Oladinrin, Olugbenga; Jayantha, Wadu; Moses, Tochukwu (Universiti Teknologi Malaysia, 2021-06-30)
    Study on New Working Practices (NWPs), which is the subject of this review paper, has created a large body of literature. Studies in this research area are progressing quickly and it is important to stay abreast of new trends and essential factors in the growth of mutual awareness. This study aims at evaluating the global scientific output of New Working Practices (NWPs) research and exploring their hotspots and frontiers from 1980 to 2018 (pre-COVID-19), using bibliometric methods. 850 relevant articles were retrieved from the Web of Science Core Collection (WoSCC) and were used for the analysis. Scientometric method and Citespace VI were used to analyse the bibliometric data. Reference citation and co-citation networks were plotted, while keywords were used to analyse the research hotspots and trends. There is a significant increase in the number of annual publications with time. The United Kingdom (UK) ranked highest in the countries with most publications, and the leading author is Friedhelm Nachreiner based on publication counts. The most cited author/organization is the UK Department of Health. Performance, work, and flexible working are the research hotspots, while flexible working arrangement represents the prominent research domain. The study offers valuable references for researchers, industry practitioners and policymakers.
  • Pure zeolite LTJ synthesis from kaolinite under hydrothermal conditions and its ammonium removal efficiency

    Kamyab, Seyedeh Mahsa; Williams, Craig D. (Elsevier, 2021-03-08)
    Linde type J zeolite was synthesized out of kaolinite raw material through hydrothermal reactions, once potassium hydroxide was used as an activator. The physicochemical characteristics of the synthesized zeolite were surveyed by using XRD, SEM/EDX, and FT-IR analytical methods. Moreover, the capability of Linde Type J zeolite for ammonium ion removal from aqueous solutions was evaluated in the present study through batch adsorption experiments. Further, the ammonium ion concentration in the remnant leachates was measured making use of the photometry analysis. Subsequently, Langmuir, Freundlich, Temkin and Dubinin–Radushkevich isotherms were applied to describe the data obtained from the adsorption studies. The findings verified the highest R2 values of Freundlich isotherm model assuming an adsorption on the heterogeneous surface. Furthermore, the kinetic studies indicated the adsorption process follows pseudo-second-order model denoting the adsorption rate controlled by the chemical sorption. In a nut shell, Linde Type J zeolite, which was synthesized from raw kaolinite, demonstrated its brilliant performance in the process of ammonium ion sorption from aqueous solutions. This can guarantee the probable potential of LTJ zeolite in purification applications.
  • Molecular phylogenetics of sub-Saharan African natricine snakes, and the biogeographic origins of the Seychelles endemic Lycognathophis seychellensis

    Deepak, V; Maddock, Simon T; Williams, Rhiannon; Nagy, Zoltán T; Conradie, Werner; Rocha, Sara; James Harris, D; Perera, Ana; Gvoždík, Václav; Doherty-Bone, Thomas M; et al. (Elsevier, 2021-03-17)
    Phylogenetic relationships of sub-Saharan African natricine snakes are understudied and poorly understood, which in turn has precluded analyses of the historical biogeography of the Seychelles endemic Lycognathophis seychellensis. We inferred the phylogenetic relationships of Seychelles and mainland sub-Saharan natricines by analysing a multilocus DNA sequence dataset for three mitochondrial (mt) and four nuclear (nu) genes. The mainland sub-Saharan natricines and L. seychellensis comprise a well-supported clade. Two maximally supported sets of relationships within this clade are (Limnophis,Natriciteres) and (Afronatrix,(Hydraethiops,Helophis)). The relationships of L. seychellensis with respect to these two lineages are not clearly resolved by analysing concatenated mt and nu data. Analysed separately, nu data best support a sister relationship of L. seychellensis with (Afronatrix,(Hydraethiops,Helophis)) and mt data best support a sister relationship with all mainland sub-Saharan natricines. Methods designed to cope with incomplete lineage sorting strongly favour the former hypothesis. Genetic variation among up to 33 L. seychellensis from five Seychelles islands is low. Fossil calibrated divergence time estimates support an overseas dispersal of the L. seychellensis lineage to the Seychelles from mainland Africa ca. 43–25 Ma, rather than this taxon being a Gondwanan relic.
  • Exploring students' perceptions and opinions about an institutional hierarchy of healthcare professionals and its impact on their inter- professional learning outcomes

    Rabani, Raiharn; Key, Michelle; Morrissey, Hana; Ball, Patrick (International Pharmaceutical Federation (FIP), 2021-04-06)
    Context: Institutional hierarchy is a phenomenon associated with clinical tribalism. Inter-professional learning is thought to improve a healthcare team's collaboration and communication. Aim: The aim was to evaluate student understanding of institutional hierarchy and perceptions and opinions on their participation in inter-professional learning. Method: Using a questionnaire, this study gathered the opinions of fourth year pharmacy students who had completed two inter-professional learning sessions. Quantitative and qualitative analyses were conducted. Results: Students (87.7%, n=50) were aware of the institutional hierarchy concept, listing the order as doctors, pharmacists, nurses then allied health. 61.4% (n=35) were willing to participate in inter-professional learning sessions. Students (70.1%, n=40) agreed that inter-professional learning sessions have added benefit to patient-centred care, and to understanding different healthcare roles in depth (82.5%, n=47) but failed in diminution of the hierarchical ideology. Conclusions: Inter-professional learning sessions did not change students' opinions about posiGoning of doctors as the top of the healthcare institutional hierarchy.
