Frictional characteristics of thin-walled tubes in liquid impact forming
Authors: Ma Jianping , Yang Lianfa , He Yulin , Guo Jian 
Published: December 2019

Purpose
This paper aims to study frictional characteristics of thin-walled tubes in the liquid impact forming (LIF) process.

Design/methodology/approach
LIF experiments under various impacting velocities were performed on SUS304 stainless steel tubes with various guiding lengths on a custom-designed measurement system to investigate the effects of impacting velocity and guiding length on the coefficient of friction (COF) in the guiding zone.

Findings
The results indicate that the COF changes dynamically in the guiding zone and decreases with the deformation process. The reduction range of the COF is wider in LIF than in both the conventional and pulsating hydroforming (THF), which may be contributed to the impacting velocities in a short time. Moreover, the COF decreases faster in the first half of the LIF process than in the second half. Under different impacting velocities and guiding lengths, the decreasing rate of the COF in the first half is more sensitive and obvious than that in the second half.

Originality/value
A method for determining the COF in the guiding zone in LIF is proposed and the frictional characteristics in LIF are studied. Comparing the COF of tubes in conventional THF, pulsating THF and the LIF process is valuable for improving and predicting the tubular formability in various hydraulic environments for industrial production.

Effect of load on the fretting behavior of SAF 2507 super duplex stainless steel in air and sea water
Authors: Wang Mengjiao , Wang Yunxia , Liu Hao , Yan Fengyuan 
Published: December 2019

Purpose
This paper aims to study the influence of load and environment medium on the fretting behavior of SAF 2507 SDSS.

Design/methodology/approach
In this study, the effect of load on the fretting behavior of SAF 2507 SDSS in air and sea water were studied. The fretting wear tests under different loads were conducted with a ball-on-flat contact configuration. The friction coefficient, wear volume, surface morphology and oxidation component were determined.

Findings
With the increase of applied load, the friction coefficient decreases both in air and sea water. The fretting mechanism is gradually transformed from partial slip regime to slip regime in air while the fretting counterparts are all in the state of gross slip in sea water. In sea water, the friction coefficient is lower while the wear loss is higher compared with that in air.

Research limitations/implications
This research suggests that the fretting behavior of SAF 2507 SDSS is related to load and environment medium.

Practical implications
The results may help us to choose the appropriate load under different environments.

Originality/value
The main originality of the research is to reveal the fretting behavior of SAF 2507 SDSS under different loads in air and sea water, which would help us to realize fretting behavior of SAF 2507 SDSS is controlled by the combination of applied load and lubricating environment.

A benchmarking study of Indian seaports
Authors: George Sajeev Abraham , Tumma Anurag C. 
Published: December 2019

Purpose
The purpose of this paper is to benchmark the operational and financial performances of the major Indian seaports to help derive useful insights to improve their performance.

Design/methodology/approach
A two-stage data envelopment analysis (DEA) methodology has been used with the help of data collected on the 13 major seaports of India. The first stage of the DEA captured the operational efficiencies, while the second stage the financial performance.

Findings
A window analysis over a period of three years revealed that no port was able to score an overall average efficiency of 100 per cent. The study identified the better performing units among their peers in both the stages. The contrasting results of the study with the traditional operational and financial performance measures used by the ports helped to derive useful insights.

Research limitations/implications
The data used in the study were majorly limited to the available sources in the public domain. Also, the study was limited to the major seaports which are under the Government of India and no comparisons were carried out with other local or international ports.

Practical implications
There is a need to prioritize investments and improvement efforts where they are most needed, instead of following a generalized approach. Once the benchmark ports are identified, the port authorities and other relevant stakeholders should work in detail on the factors causing inefficiencies, for possible improvements in performance.

Originality/value
This paper carried out a two-stage DEA that helped to derive useful insights on operational efficiency and financial performance of the India seaports. A combination of the financial and operational parameters, along with a comparison of the DEA results with the traditional measures, provided a different perspective on the Indian seaport performance. Considering the scarcity of research papers reported in the literature on DEA-based benchmarking studies of seaports in the Indian context, it has the potential to attract future research in this field.
Annual report readability subsequent to going-concern opinions
Authors: Kawada Brett S. , Wang Jeff Jundong 
Published: December 2019

PurposeThis study aims to examine a firm’s disclosure properties subsequent to receiving a going-concern opinion.Design/methodology/approachA difference-in-difference research design was used to control for endogeneity issues. Annual report readability is used as a proxy for firm disclosure.FindingsThe results indicate a negative and significant association between issuance of a going-concern report to a firm and the firm’s readability index in the subsequent year. In other words, after receiving a going-concern opinion, a firm’s annual report exhibits increased readability. The results, when broken into subsamples of surviving and failing firms, are concentrated in the surviving firms.Research limitations/implicationsPrior research has shown that firms change their disclosure properties due to endogenous choices motivated by incentive or exogenous shocks. The results of this study, however, suggest that firms that receive going-concern opinions are incentivized to be more forthcoming in disclosing their financial information.Originality/valueTo the authors’ knowledge, this study is the first to investigate how firms’ general disclosures change subsequent to receiving a going-concern opinion.

Published: December 2019

AbstractObjectivesTo examine the efect of age and gender on dental services provided by dentists in Australia, and compare with previous estimates across the period 1983–1984 to 2013–2014.MethodsData were collected by mailed survey from a random sample of Australian dentists. Private sector dentists were the focus of the analysis. Data were weighted to the age and sex distribution of Australian practising dentists.ResultsThe analysis was based on service logs collected from n = 211 dentists. Adjusted results (rate ratio, 95% CI) showed male dentists had higher endodontic rates (1.7, 1.0–2.9) than female dentists. Dentists aged 40–49 years had higher restorative rates (1.6, 1.1–2.2) but lower preventive rates (0.5, 0.3–0.9) than those aged 20–29 years. Diagnostic services were lower for dentists aged 40–49 to 60+ years (0.8, 0.6–0.9), while denture services were higher for dentists aged 40–49 (11.1, 2.5–48.5) to 60+ years (6.4, 1.2–33.3). Crowns were higher for dentists aged 40–49 (2.4, 1.0–5.6) and 50–59 years (2.9, 1.3–6.6). Diagnostic and preventive services were consistently higher across 1983–1984 to 2013–2014.ConclusionsYounger dentists provided higher rates of diagnostic and preventive services. Over a 30‐year period, there was a consistent trend towards higher provision of diagnostic and preventive services.

AbstractObjectiveTo investigate the research interest, capacity and culture in individuals, teams and health organisations across south‐western Victoria.DesignCross‐sectional survey.SettingEight public health services in the south‐western region of Victoria.ParticipantsAll staff were invited to participate.InterventionHospital staff survey.Main outcome measureThe Research Capacity and Culture tool.ResultsThe survey was completed by 776 staff including nurses, allied health staff and doctors. Half of the respondents were currently involved in research, while most wanted to be more involved. Respondents reported having moderate research skills and success at individual, team and organisation levels. Women and nurses reported having lower skills than comparable groups. Motivators for undertaking research were skill development (increased job satisfaction and brain stimulation) while the most commonly selected barriers were lack of time, other work taking priority and lack of funding.ConclusionHealth organisations in regional and rural Victoria could harness opportunities to enable staff participation in research by supporting identified strengths, addressing barriers and providing “permission” for staff to get involved in research. Efforts to improve research capacity among women and nurses could lead to the greatest overall improvement in organisations' research capacity and output—and translation of evidence into practice.

AbstractBackgroundDiabetes mellitus is one of the risk factors for male subfertility/infertility. Malaysian propolis is reported to decrease hyperglycaemia in diabetic state.ObjectivesThe present study investigated the protective effect of Malaysian propolis on diabetes‐induced subfertility/infertility. Additionally, its combined beneficial effects with metformin were investigated.Materials and methodsForty adult male Sprague Dawley rats were randomly assigned into five groups, namely normal control, diabetic control, diabetic + Malaysian propolis (300 mg/k.g. b.w.), diabetic + metformin (300 mg/kg b.w.) and diabetic + Malaysian propolis + metformin. Diabetes was induced using a single intraperitoneal injection of streptozotocin (60 mg/kg b.w.) and treatment lasted for 4 weeks. During the 4th week, mating behavioural experiments were performed using sexually receptive female rats. Thereafter, fertility parameters were assessed in the female rats.ResultsMalaysian propolis increased serum and intratesticular free testosterone levels, up‐regulated the mRNA levels of AR and luteinizing hormone receptor, up‐regulated the mRNA and protein levels of StAR, CYP11A1, CYP17A1, 3β‐HSD and 17β‐HSD in the testes of diabetic rats. Furthermore, Malaysian propolis up‐regulated testicular MCT2, MCT4 and lactate dehydrogenase type C mRNA levels, in addition to improving sperm parameters (count, motility, viability and normal morphology) and decreasing sperm nDNA fragmentation in diabetic rats. Malaysian propolis improved mating behaviour by increasing penile guanosine monophosphate levels. Malaysian propolis also improved fertility outcome as seen with decreases in pre‐ and post‐implantation losses, increases in gravid uterine weight, litter size per dam and foetal weight. Malaysian propolis's effects were comparable to metformin. However, their combination yielded better results relative to the monotherapeutic interventions.ConclusionMalaysian propolis improves fertility potential in diabetic state by targeting steroidogenesis, testicular lactate metabolism, spermatogenesis and mating behaviour, with better effects when co‐administered with metformin. Therefore, Malaysian propolis shows a promising complementary effect with metformin in mitigating Diabetes mellitus‐induced subfertility/infertility.

AbstractIntroductionThe goal of partial nephrectomy for renal tumors is complete tumor removal with the preservation of renal function and no complications. Trifecta (total ischemia time < 25 minutes, negative surgical margins, and no surgical complications) is widely used to evaluate success after partial nephrectomy. We investigated factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy.MethodsSixty‐six patients who underwent laparoscopic partial nephrectomy for clinical T1a renal masses between December 2006 and March 2016 were examined. We defined preserved renal function as the preservation of an estimated glomerular filtration rate ≥ 90% 1 year after surgery. We examined factors affecting renal function preservation among patients not achieving trifecta after laparoscopic partial nephrectomy.ResultsThirty out of 66 patients (45%) did not achieve trifecta. In an evaluation of 66 patients, a multivariate analysis identified tumor size (P = .04) as an independent predictor affecting the achievement of trifecta. Tumor size was significantly smaller in the trifecta achievement group (1.9 ± 0.1 cm) than in the non‐achievement group (2.2 ± 0.6 cm) (P = .04). We found that renal function was preserved 1 year after surgery in 14 out of the 30 patients not achieving trifecta. In univariate analysis, age (P = .01) was significantly associated with affecting the preservation of renal function among these patients. Patients with preserved renal function were significantly younger (47.8 ± 2.5 years) than those without (58.5 ± 2.9 years) (P = .01).ConclusionRenal function may be preserved in younger patients even if they do not achieve trifecta after partial nephrectomy for small renal masses.
Keys to engagement: A case study exploring the participation of autistic pupils in educational decision‐making at school
Authors: Zilli Chantelle , Parsons Sarah , Kovshoff Hanna 
Published: December 2019

BackgroundThe UNCRC (1989) established the importance of listening to children’s views globally. In England, seeking the views of pupils with special educational needs and disability about their education, and involving them in decision‐making, has been mandatory since 2015. Autistic children’s views and experiences are particularly underrepresented in this context.AimsTo provide a detailed exploratory analysis of practices that enable autistic pupils to participate in educational decision‐making, and to generate new knowledge about pupil participation in a school context, using the Framework for Participation (Black‐Hawkins, 2010) as an analytical frame.SampleFour male pupils aged 11–15, with autism spectrum diagnoses, and 11 staff members from a specialist, independent school took part in this case study.MethodsObservations were made of pupils in lessons, and pupils completed a photo‐voice activity focusing on where they felt ‘most listened to’ in the school. Staff members participated in semi‐structured interviews.ResultsA range of practices supported pupils’ participation in everyday decision‐making, underpinned by a respectful and positive culture led by the senior management team. The focus was on what learners can do and how they make decisions to facilitate achievement. Pupils and staff developed mutually respectful relationships, within which boundaries were negotiated and compromises offered. Flexibility through decision‐making was provided within the timetabling and content of the curriculum. Pupils’ special interests and expertise were valued as ‘keys’ to supporting their engagement.ConclusionsThese insights provide a tool for reflection by educators and educational psychologists for considering how they might promote the participation of autistic pupils in different educational contexts.

AbstractLoss of habitats or ecosystems arising from development projects (e.g., infrastructure, resource extraction, urban expansion) are frequently addressed through biodiversity offsetting. As currently implemented, offsetting typically requires an outcome of “no net loss” of biodiversity, but only relative to a baseline trajectory of biodiversity decline. This type of “relative” no net loss entrenches ongoing biodiversity loss, and is misaligned with biodiversity targets that require “absolute” no net loss or “net gain.” Here, we review the limitations of biodiversity offsetting, and in response, propose a new framework for compensating for biodiversity losses from development in a way that is aligned explicitly with jurisdictional biodiversity targets. In the framework, targets for particular biodiversity features are achieved via one of three pathways: Net Gain, No Net Loss, or (rarely) Managed Net Loss. We outline how to set the type (“Maintenance” or “Improvement”) and amount of ecological compensation that is appropriate for proportionately contributing to the achievement of different targets. This framework advances ecological compensation beyond a reactive, ad‐hoc response, to ensuring alignment between actions addressing residual biodiversity losses and achievement of overarching targets for biodiversity conservation.

AbstractIntroductionBacterial pleuritis is one of the most important pleural and respiratory infectious diseases, in addition, there have been no reports describing the clinical characteristics of patients with bacterial pleuritis according to molecular methods. An accurate understanding of the clinical characteristics and etiology of bacterial pleuritis is an issue that must be addressed.ObjectivesThe aim of this study was to clarify the clinical characteristics of the bacterial species in bacterial pleuritis.MethodsPleural effusion samples were obtained from 29 patients with bacterial pleuritis. The microbiota of pleural effusion samples was analyzed by clone library analysis using the 16S ribosomal RNA gene.ResultsThe phylotypes of Fusobacterium spp. (24.1%) were most frequently the predominant phylotypes, followed by those of Streptococcus anginosus group (SAG) (20.7%) and S. aureus (17.2%). The predominant phylotypes of obligate anaerobes, including the Fusobacterium spp., were detected in 11 of 29 patients (37.9%). Patients in the SAG group were significantly older and presented lower serum albumin levels than those in the obligate anaerobe and other bacterial groups. Patients from the obligate anaerobe group took longer to present symptoms, and therefore the diagnosis of pleuritis was also delayed, in comparison to patients in the other bacterial groups.ConclusionsOur results demonstrated that there were characteristic differences between patients in SAG, obligate anaerobe and other bacterial groups. Physicians may need to consider treatment strategy options based on the clinical characteristics of patients with bacterial pleuritis.

Published: December 2019

AbstractChronic Obstructive Pulmonary Disease (COPD) is a chronic respiratory disease characterised by persistent respiratory symptoms and airflow limitation. COPD has a major impact on public health, mainly because of its increasing prevalence, morbidity and mortality. The natural course of COPD is aggravated by episodes of respiratory symptom worsening termed exacerbations that contribute to disease progression. Acute Exacerbations of COPD (AECOPD) can be triggered by a multitude of different factors, including respiratory tract infections, various exposures, prior exacerbations, non‐adherence to treatment and associated comorbidities. AECOPD are associated with an inexorable decline of lung function and a significantly worse survival outcome. This review will summarise the most important aspects regarding the impact of different factors that contribute to COPD exacerbations.
