Shareholder use of CSR reports: an accountability perspective
Authors: Smith Veronica , Lau James , Dumay John 
Published: August 2021

Purpose
This paper aims to investigate the extent of shareholder engagement and satisfaction with corporate social responsibility (CSR) reports of a Chinese-owned company compared to an Australian-owned company in the Australian mining industry. The study is motivated by the speed, extent and nature of Chinese foreign direct investment in Australia, the resulting negative social attitudes and the impact on the perceptions of a report’s credibility.

Design/methodology/approach
The authors conducted a survey of 202 minority shareholders of two Australian mining companies, one has a Chinese majority shareholder and the other an Australian majority shareholder. The responses highlight users’ comparative perceptions of corporate motivations for reporting, the level of perceived shareholder power over reporting decisions and the resulting propensity to read CSR reports.

Findings
The authors found that, contrary to decision-usefulness theory, which posits that users will read CSR reports only if they are deemed to be reliable, that perceptions of poor credibility and poor CSR performance actually result in a higher propensity to read the reports. This suggests that the minority shareholders of the Chinese acquired firm are using reports to monitor the level of corporate accountability.

Originality/value
The findings have implications for firms operating in politically or socially sensitive industries that are likely to use CSR reporting as a legitimising strategy. The paper also provides guidance to regulators in the provision of information, which is meaningful to minority shareholders.

Authors: Kai Chun-Mei , Zhang Feng-Jun , Cheng Cong-Liang , Chen Qian-Bao 
Published: August 2021

Purpose
The purpose of this paper is to study the influence of different factors on mud performance, find the best conditions and synthesize a new type of anti-collapse drilling polymer mud with higher stability. The anti-collapse mechanism of drilling polymer mud was also suggested.

Design/methodology/approach
Exploring the influence of different molecular weight thickeners, filtrate reducers, soda ash addition and film-forming components on the mud performance, so as to obtain the best ratio of anti-collapse drilling polymer mud.

Findings
The results show that the use of vegetable glue, sulfonate copolymer and vegetable fiber powder can synthesize a high-viscosity, high-stability, collapse-resistant mud. When the mass ratio of vegetable fiber powder: vegetable glue: sulfonate copolymer is 40:1:2, the mud viscosity is 21.2 s, the fluid loss in 30 min is only 12.5 mL, and the mud film thickness is 1.5 mm, which is one ideal anti-collapse polymer mud.

Originality/value
Compared with ordinary polymer mud and bentonite mud, this anti-collapse polymer mud not only uses vegetable glue instead of traditional tackifiers but also effectively uses vegetable fiber powder produced from waste wood, which is environmentally friendly and highly stable specialty. It can effectively improve the safety and quality of construction during drilling in water-sensitive geology.
Improving surface roughness of polylactic acid (PLA) products manufactured by 3D printing using a novel slurry impact technique
Authors: Heshmat Mahmoud , Abdelrhman Yasser 
Published: August 2021

Purpose
Fused deposition modeling (FDM) is one of the most adopted additive manufacturing techniques to produce prototypes and/or final parts regardless of geometrical complexity restrictions. One of the most challenging aspects of this technology is the attainable roughness. The purpose of this study is to evaluate the capability of the slurry impacts to improve the surface roughness of parts fabricated using FDM. Moreover, a regression model for predicting the values of surface roughness was developed.

Design/methodology/approach
The developed technique imposes a silica–water mixture which softens the staircase on the surface and leaves it smoother. The process introduces three main factors: building orientation; layer thickness; and impact angle of the slurry particles. Experimentally, a test rig was used to evaluate the effect of these factors on surface roughness. Statistically, Analysis of variance (ANOVA) and regression analysis were conducted to study the contribution of the individual factors on the roughness.

Findings
The results reveal that the effect of slurry impacts has a good impact on surface roughness, and the three factors have significant effect on surface roughness.

Originality/value
This paper contributes to new knowledge by providing a new technique for enhancing the surface roughness of FDMed products. ANOVA and regression analysis is a useful tool to parametrically study the surface roughness in terms of building and testing factors.
Effects of extruder temperatures and raster orientations on mechanical properties of the FFF-processed polylactic-acid (PLA) material

Published: August 2021

Purpose
The purpose of this study is to investigate the influences of extruder temperatures and raster orientations on the mechanical properties of polylactic-acid (PLA) material processed by using fused filament fabrication (FFF).

Design/methodology/approach
In this research, the PLA specimens were first printed with nozzle or extruder temperatures of 205°C, 215°C and 225°C and then evaluated in terms of their physical, chemical and mechanical properties. An appropriate extruder temperature was then selected based on this experiment and used for the printing of the other PLA specimens having various raster orientations. A series of tensile tests were carried out again to investigate the influence of raster orientations on the tensile strength, tensile strain and elastic modulus of those FFF-processed PLA materials. In the end, the one-way ANOVA was applied for the statistical analysis and the Mohr’s circle was established to aid in the analysis of the data obtained in this experiment.

Findings
The result of this study shows that the chemistry, porosity, degree of crystallinity and mechanical properties (tensile strength, strain and elastic modulus) of the PLA material printed with a raster angle of 0° were all insensitive to the increasing extruder temperature from 205°C to 225°C. Meanwhile, the mechanical properties of such printed PLA material were obviously influenced by its raster orientation. In this case, a PLA material with a raster orientation parallel to its loading axis, i.e. those with a raster angle of θ = 0°, was found as the strongest material. Meanwhile, the raster configuration-oriented perpendicular to its loading axis or θ = 90° yielded the weakest PLA material. The results of the tensile tests for the PLA material printed with bidirectional raster orientations, i.e. θ = 0°/90° and 45°/−45° demonstrated their strengths with values falling between those of the materials having unidirectional raster θ = 0° and 90°. Furthermore, the result of the analysis by using a well-known Mohr’s circle confirmed the experimental tensile strengths and the failure mechanisms of the PLA material that had been printed with various raster orientations.

Originality/value
This study presented consistent results on the chemistry, physical, degree of crystallinity and mechanical properties of the FFF-processed PLA in responding to the increasing extruder temperature from 205°C to 225°C applied during the printing process. Unlike the results of the previous studies, all these properties were also found to be insensitive to the increase of extruder temperature. Also, the result of this research demonstrates the usability of Mohr’s circle in the analysis of stresses working on an FFF-processed PLA material in responding to the changes in raster orientation printed in this material.
Interaction between social enterprises and key actors shaping the field: experiences from the social and health sectors in Hungary
Authors: Kiss Julianna , Krátki Noémi , Deme Gábor 
Published: August 2021

PurposeIn Hungary, as in other Central and Eastern European countries, the concept of social enterprise (SE) has attracted increased attention in recent years, with certain key actors shaping the organisational field. This growing interest is largely because of the availability of European Union funds focussing on the work integration of disadvantaged groups but ignoring other possible roles of SEs. This study aims to consider a seldom examined and underfunded area: SEs’ institutional environment and organisational activities in the social and health sectors.Design/methodology/approachBased on neoinstitutional theory, the paper uses desk research and qualitative case studies. It presents the experiences of SEs providing social and health services for specific disadvantaged groups.FindingsThis paper identified the key actors influencing the everyday operation of SEs and examined their connections, interactions and partnerships. Based on the findings, SEs primarily depend on the central state, public social and health institutions and local governments. At the same time, their connections with private customers, networks, development and support organisations, third sector organisations and for-profit enterprises are less significant. The key actors have a relevant impact on the legal form, main activities and the financial and human resources of SEs. SEs, however, have little influence on their institutional environment.Originality/valueThe paper contributes to understanding the opportunities and barriers of SEs in Hungary and, more generally, in Central and Eastern Europe, especially regarding their place in social and health services.

Published: August 2021

Purpose
The purpose of this research paper is to predict sustainability-driven entrepreneurship intention among university students in the developing market (Pakistan).

Design/methodology/approach
The target population of this study was university students in Pakistan. According to UNDP (2017) report, Pakistan has the largest youth population. More than 64% of the total population (210 million) is below 30 years of age. If trained properly, this huge chunk of the population could become a source of intellectual capital for the development of the nation. The quota based on age sampling technique was used to collect the data from university students in Karachi because more than 64% of the Pakistan population is below 30 years of age.

Findings
The findings reveal that university entrepreneurial support has a strong influence on attitude toward sustainable entrepreneurship and entrepreneurial self-efficacy.

Research limitations/implications
The role of university entrepreneurial support, environmental concern and students’ entrepreneurial self-efficacy are vital factors in sustainability-driven entrepreneurship. This study enriches the literature of green entrepreneurship helping to understand university students’ intention for sustainable entrepreneurship. The outcome of this study would help strategists and environmental academicians to guide university students regarding the launch of sustainable ventures.

Originality/value
To the best of authors’ knowledge, this is one of the first studies to explore the effects of environmental concern on entrepreneurial intention among university students in the context of a developing country – Pakistan.
Factors that influence non‐word repetition performance in children with and without persistent speech sound disorders
Authors: Farquharson Kelly , Hogan Tiffany P. , Fox Annie B. 
Published: August 2021

AbstractBackgroundNonword repetition (NWR) is a common phonological processing task that is reported to tap into many cognitive, perceptual, and motor processes. For this reason, NWR is often used in assessment batteries to aid in verifying the presence of a reading or language disorder.AimsTo examine the extent to which child‐ and item‐level factors predict the probability of a correct response on a non‐word repetition (NWR) task in a sample of children with persistent speech sound disorders (P‐SSDs) compared with their typically developing peers.Methods & ProceduresA total of 40 American‐English‐speaking children were tested on an NWR task for which the stimuli were manipulated for phonological neighbourhood density and list length. Additional measures of vocabulary and word reading were also administered.Outcomes & ResultsChildren who were typically developing were 1.82 times more likely than children with P‐SSD to respond correctly. The item‐level factor of phonological neighbourhood density influenced performance, but only for the P‐SSD group, and only at certain list lengths. Vocabulary and word‐reading ability also influenced NWR task performance.Conclusions & ImplicationsChildren with P‐SSD present as a complex and heterogeneous group. Multiple factors contribute to their ability to perform phonological tasks such as NWR. As such, attention to the item‐level factors in screenings and assessments is necessary to ensure that appropriate decisions are made regarding diagnosis and subsequent treatment.What this paper addsWhat is already known on the subject?Good expressive vocabulary is important for children with speech sound disorders; it can aid in their performance on phonological processing tasks like NWR.
Nonword repetition may be a helpful test/ subtest to add to assessment batteries when evaluating children with speech sound disorders.
What this paper adds to existing knowledge?
Vocabulary and word reading abilities must also be measured for children with SSDs, to observe the bigger picture of their linguistic abilities.

What are the potential or actual clinical implications of this work?
The relation between word reading and speech sound production influences performance on phonological processing tasks.

Published: August 2021

AbstractIntroductionUnintentional weight loss is an important clinical problem. The role of CT is not firmly established in the workup of these patients. The aim of this study is to determine the diagnostic yield of CT Thorax, Abdomen and Pelvis (CT TAP) in patients with unexplained weight loss and to determine whether clinical or laboratory variables are associated with positive CT findings.MethodsA retrospective review was performed of CT TAP examinations over 12 months with weight loss as an indication. Patients’ electronic records and radiology reports were reviewed. Clinical and laboratory variables were assessed for correlation with positive findings on CT.Results461 CT TAP studies with weight loss as the primary indication were identified. 124 were excluded; 82 due to a recent history of malignancy, 41 because CT TAP was used for staging of a new malignancy and one study was incomplete. This left 337 eligible examinations. 217 studies had findings of no clinical relevance, 50 studies were normal, 40 studies identified a possible cause of weight loss and 30 studies identified a definite cause. Of the 40 where a possible cause was identified, further work up led to a diagnosis which explained the weight loss in 13 patients. The diagnostic yield of CT TAP was 12.8%. Age, abdominal symptoms, degree of weight loss, anaemia, tumour markers and LDH did not significantly correlate with positive findings on CT.ConclusionCT TAP is a helpful investigation in patients with unexplained weight loss with a diagnostic yield of 12.8%.

Published: August 2021

AbstractObjectivesOnly 5% to 10% of patients who visit the emergency department (ED) with isolated dizziness without neurologic abnormalities may have central lesions; however, it is important to distinguish central lesions through brain imaging. This study was conducted to create a nomogram to provide an objective medical basis for selectively performing magnetic resonance imaging (MRI) among patients with isolated dizziness.MethodsThis retrospective observational study enrolled patients who visited the ED of a tertiary hospital with isolated dizziness and underwent diffusion‐weighted MRI and subsequently consulted with the departments of neurology, neurosurgery, or otorhinolaryngology. Multivariable logistic regression analysis was performed to identify risk factors in patients diagnosed with central lesions to create a nomogram with the significant variables.ResultsOf the 1,078 patients who were screened, 119 were diagnosed with central lesions. Significant variables in the multivariable logistic regression analysis were albumin levels (odds ratio [OR] = 0.339, 95% confidence interval [CI] = 0.188 to 0.610, p = 0.0003), inorganic phosphate levels (OR = 0.891, 95% CI = 0.832 to 0.954, p = 0.0010), history of ischemic stroke (OR = 3.170, 95% CI = 1.807 to 5.560, p < 0.0001), presyncope (OR = 3.152, 95% CI = 1.184 to 8.389, p = 0.0216), and nystagmus (OR = 0.365, 95% CI = 0.237 to 0.561, p < 0.0001). The area under the receiver operating characteristic curve of the nomogram created with these variables was 0.7315 (95% CI = 0.6842 to 0.7788, p < 0.0001).ConclusionsAlbumin, inorganic phosphate, previous stroke, presyncope, and nystagmus were associated with the predictive diagnosis of central lesions among patients admitted to the ED with isolated dizziness. The novel nomogram created using these variables can help in objectively determining the need for MRI in patients presenting with isolated dizziness to the ED.

Published: August 2021

AbstractThis paper investigates the effect of COVID‐19 on the global stock market. Specifically, we test whether the growth in the number of confirmed cases/deaths affects market quality, measured by return, realised volatility, jumps and co‐jumps for 43 stock indices around the world. We find that an increase in the growth rate of the number of confirmed cases increases volatility and jumps while reducing return. Further, we explore whether economic, financial and political risks play any significant role in the relation between the number of confirmed cases/deaths and market quality. Overall, we find the risk from COVID‐19 overshadows these risks.
Size variation in wild Bactrocera tryoni (Diptera: Tephritidae): only a small amount is related to the host fruit
Authors: Newman Jaye D , Merkel Katharina , Clarke Anthony R 
Published: August 2021

AbstractBody size is an indicator of fitness in fruit flies (Diptera: Tephritidae), with larger males and females having increased mating success and egg production, respectively. Based on laboratory studies, the larval diet and its nutritional composition are considered the most important factors influencing juvenile growth and subsequent adult body size. However, a very limited literature is less clear on the importance of larval diet as an adult size modifier of wild fruit flies. Bactrocera tryoni (Froggatt) is a polyphagous species with larvae feeding within the fruit of over 200 plant species. To test the impact of larval host on adult size in wild individuals of this species, we collected naturally infested fruit from the field and then reared out adults in the laboratory. The wing length and dry body weight of emergent flies were measured. Linear mixed models were used to analyse the difference in size depending on fruit type, larval density, sex and their interactions. Separate measurements of body size, wing length and dry body weight were significantly influenced by the larval host fruit collected from the field. However, only 7% and 24% of the variation of the wing discal–medial cell length and dry body weight, respectively, could be explained by larval host fruit type with high individual body size variation both within and between host fruit types. Fruit protein content was positively correlated, and water content negatively correlated, to wing discal–medial cell length. Unexpectedly, the parameters of wing length and dry body weight were only weakly correlated with each other. The results support the large body of laboratory‐based fruit fly diet work, which identifies protein as a key component of the larval diet, but do not support a general assumption that larval host is the key driver of adult body size variation in wild frugivorous tephritids. Rather, and in agreement with a small number of laboratory‐based trials, the importance of larval diet to adult fitness appears to become less important as the larval feeding environment becomes more complex.

AbstractBackground and ObjectivesDrug courts provide an array of substance use treatments and community‐based services for probationers struggling with substance use disorders. We assessed substance use treatment services utilization and related expenditures and relapse and recidivism outcomes and identified predictors of cost of provision of substance use treatment services in a matched cohort of Massachusetts probationers in drug courts and traditional courts.MethodsThis was an observational quasi‐experimental study with 542 propensity‐score‐matched probationers initiating drug court between August 1, 2015 and February 28, 2018 and a minimum 6‐month follow‐up period.ResultsA significantly greater proportion of probationers in drug courts were female, self‐reported opioids as their primary drug of choice, had a history of substance use treatment, and a high and very high risk of recidivism than their counterparts in traditional courts. We estimated that the provision of substance use treatment services was $1498 more expensive for probationers in drug courts than traditional courts (p = .054). There were no statistically significant differences in relapse or recidivism rates between court systems.Discussion and ConclusionsProbationer's age, gender, risk of recidivism at court intake, and enrollment length were strong predictors of expenditures on substance use treatment services.Scientific SignificanceThis was the first study to assess substance use treatment services utilization and outcomes among probationers in drug courts and traditional courts. Drug courts served the needs of probationers disproportionally impacted by nonserious drug‐related offenses struggling with substance use disorders who were at a high and very high risk of recidivism at court intake.
