Dynamical stability in the vicinity of Saturnian small moons: the cases of Aegaeon, Methone, Anthe, and Pallene
Authors: Rodríguez Adrián , Callegari Jr. N 
Published: June 2021

ABSTRACT
In this work we analyse the orbital evolution and dynamical stability in the vicinity of the small Saturnian moons Aegaeon, Methone, Anthe, and Pallene. We numerically resolve the exact equations of motions to investigate the orbital motion of thousands of test particles within and near the domain of the 7/6, 14/15, 10/11 mean-motion resonances of Aegaeon, Methone, and Anthe with Mimas, respectively. We show that, for massless small moons, the orbits of particles initially restricted to the resonant domains remain stable for at least 104 yr. We also conduct numerical simulations considering Aegaeon, Methone, Anthe, and Pallene as massive bodies. The results show that most particles undergo significant perturbations in their orbital motions, ultimately destabilizing on time-scales of a few hundreds of years or even less through collisions with the four small moons. In addition, we also simulate the orbital evolution of test particles initially distributed in the form of arcs around Aegaeon, Methone, and Anthe. We show that the initial arcs are dynamically eroded on time-scales of hundreds of years, allowing us to constrain the time-scales on which gravitational forces operate to remove particles from the observed arcs.

Punishment for Apostasy: Arguments from Two Traditionally Trained Muslim Scholars in Favor of its Abolition
Authors: Akbar Ali 
Published: June 2021

Abstract
This article explores and compares the views of two traditionally educated Muslim scholars, namely Taha Jabir al-Alwani (d 2016) and Hussein Ali Montazeri (d 2009), about the classical rulings on apostasy in Islam. The article argues that both al-Alwani, a Sunni scholar educated at al-Azhar, and Montazeri, a graduate of the Shiʿi seminary in Qom, defend freedom of religion in the sense of converting from Islam to another religion—an idea that stands in sharp opposition to the classical rulings on apostasy in Islamic sources which prescribe capital punishment for such an act. As the article demonstrates, these scholars’ views, despite certain differences in their method of argumentation, advance the development of new ideas about religious freedom in Islamic scholarship, especially among traditional circles.
Cardiac tamponade due to ruptured cystic teratoma: report of two cases
Authors: Kang Do Kyun , Kang Min Kyun , Heo Woon , Hwang Youn-Ho 
Published: June 2021

ABSTRACT
We report the rare two cases of cardiac tamponade due to ruptured cystic teratoma. In both cases, a chest computed tomography scan showed large cystic mass with large amount of pericardial effusion. Transthoracic echocardiogram revealed cardiac tamponade physiology. En bloc resection of the mass was performed and pathologic examination showed mature cystic teratoma. The postoperative course of patients was uneventful. A cystic mediastinal teratoma should be considered in the differential diagnosis of pericardial effusion.
Point-of-Care Ultrasound of a Shoulder Effusion in a Child With Septic Arthritis
Authors: Firnberg Maytal T. , Rabiner Joni E. 
Published: June 2021

Abstract
Point-of-care musculoskeletal ultrasound can facilitate diagnosis of joint effusions and help guide management of suspected septic joints. This case report describes a previously healthy pediatric patient with acute onset shoulder pain and fever who was found to have leukocytosis and bacteremia. Point-of-care ultrasound (POCUS) demonstrated a unilateral shoulder joint effusion. After POCUS was performed, purulent fluid was aspirated from the joint, and she was diagnosed with a septic shoulder. We review the ultrasound technique, sonographic findings, and literature regarding POCUS for shoulder effusions.
Grid – connected operation and performance of hybrid DG having PV and PEMFC
Authors: Shetty Nayana , R.L. Chakrasali 
Published: June 2021

Purpose
“the purpose of this study/paper” or “this study/paper aims to” in the Purpose section of the Abstract. The integration of distributed generation (DG) to the utility grid is yet another approach to provide reliable and secured power.

Design/methodology/approach
The significant concern in this contemporary world are the day-to-day increasing power demand, lack of energy and increasing environmental pollution, which are threatening the existence of living things.

Findings
The research focus here is to adequacy and security in the grid-integrated hybrid distributed generation (DG) having photovoltaic (PV) and proton exchange membrane fuel cell.

Originality/value
PV system is a clean source of generation and suitable for many applications. Photovoltaic cell captures the energy from solar irradiation. To track the maximum power from PV, perturb and observe method is used. As it is intermittent in nature, integrating PV with fuel cell makes the hybrid source more reliable. Power electronic interfacing devices are used to integrate this hybrid DG source to microgrid. The simulation of this grid-connected hybrid DG is performed using Matlab/Simulink environment.
Perceived usefulness and adoption of Koha integrated library systems by librarians in universities in Southern Nigeria
Authors: Jamogha Ejiro , Owoeye Jide , Godwin Lucky Stephen 
Published: June 2021

Purpose
This paper aims to study the perceived usefulness and adoption of Koha Integrated Library System (ILS) by librarians in universities in Southern Nigeria.

Design/methodology/approach
The study adopted a survey method. The researchers designed a structured questionnaire using Google form and shared it online. Data were gathered from respondents whose libraries had adopted Koha.

Findings
Koha was highly perceived useful in acquisition, cataloguing, circulation and serials operations. There was moderate adoption of Koha generally. However, it was rarely adopted for making payment and placing of orders for book purchases and serial subscriptions. Perceived usefulness had positive influence on Koha’s adoption. Inadequate training of library staff on Koha use was a major challenge to Koha adoption. Hence, it was recommended that there should be regular training on the use of Koha and strategic decisions that would enhance the useful objectives behind the gunning for Koha, should be taken and implemented by the management of libraries.

Originality/value
The study highlighted the perceived usefulness of Koha and the extent to which it has been adopted by librarians in the university libraries under study. It will avail the management of these libraries the opportunity to re-evaluate if the ILS is well maximized in terms of adoption and usefulness.
Global research on library service quality: a bibliometric analysis and knowledge mapping
Authors: Ashiq Murtaza , Ur Rehman Shafiq , Muneeb Dilnaz , Ahmad Shakil 
Published: June 2021

Purpose
This study aims to examine the publishing and citation trends on library service quality (LSQ) in the past five decades (1972–2020). Additionally, this bibliometric study investigates the top authors, countries, organizations, journals, nature of collaboration, highly cited articles and LSQ sub-areas.

Design/methodology/approach
Bibliometric analysis has been used to extract data from the Scopus and Web of Science (WOS) databases. A comprehensive search strategy was devised to extract relevant data from both data sources. Finally, 341 Scopus and 212 WOS records were selected. Data analysis has been performed using VOS viewer software, Biblioshiny, Cite Space and Excel.

Findings
It was found that a total of 443 items were published in Scopus (n = 341) and WOS (n = 212) during this period. The largest number of studies were published in the year 2019 (n = 29), and the USA was found to be the most productive country, with the most productive organizations, authors and author collaborations. The Texas A&M University in Texas, USA, had the top three most productive authors (Cook C, Thompson B and Heath F) and was the most productive organization. The Performance Measurement and Metrics Journal is on the top of the list. The single author was the prevailing authorship pattern, followed by the two-authors pattern. The most collaborating countries were identified as the UK, Japan, Spain and Bangladesh. The keyword analysis informed that the published literature on LSQ mainly concentrated on academic libraries, Therefore, there is a need further to examine other types of libraries including public, national, special libraries.

Originality/value
To the best of the knowledge, this seems to be the first comprehensive bibliometric study that combined productivity and citations, citation impact to present a holistic picture of the LSQ literature.
Accessible authentication: dyslexia and password strategies
Authors: Renaud Karen , Johnson Graham , Ophoff Jacques 
Published: June 2021

Purpose
The purpose of this paper is to reveal the lived experiences of dyslexics in engaging with all kinds of alphanumeric authentication mechanisms.

Design/methodology/approach
A significant proportion of the world’s population experiences some degree of dyslexia, which can lead to spelling, processing, sequencing and retention difficulties. Passwords, being essentially sequences of alphanumeric characters, make it likely that dyslexics will struggle with these, even more so than the rest of the population. Here, this study explores the difficulties people with dyslexia face, their general experiences with passwords, the coping strategies they use and the advice they can provide to developers and others who struggle with passwords. This paper collects empirical data through semi-structured interviews with 13 participants. Thematic analysis was used to provide an in-depth view of each participant’s experience.

Findings
The main contribution of this paper is to provide evidence related to the inaccessibility dimensions of passwords as an authentication mechanism, especially for dyslexics and to recommend a solution direction.

Research limitations/implications
There is a possible volunteer bias, as this study is dealing with self-reported data including historical and reflective elements and this paper is seeking information only from those with self-declared or diagnosed dyslexia. Furthermore, many expressed interest or curiosity in the relationship between dyslexia and password difficulties, for some a motivation for their participation. Finally, given that the participants told us that dyslexics might hide, it is possible that the experiences of those who do hide are different from those who chose to speak to us and thus were not hiding.

Originality/value
A few authors have written about the difficulties dyslexics face when it comes to passwords, but no one has asked dyslexics to tell them about their experiences. This paper fills that gap.
Burnout in emergency medical technicians and paramedics in the USA
Authors: Sporer Celia 
Published: June 2021

PurposeThis study was designed to examine burnout in US emergency medical services (EMS) providers. It examined burnout scores measured using the Maslach Burnout Inventory (MBI) on a convince sample of US EMS providers as well individual variables associated of burnout in this population.Design/methodology/approachThis study used a convince sample, recruited using social media, of EMTs and paramedics and engaged them in an online survey to obtain information on burnout in this population. The responses were analyzed using stand statistical approached in order to determine MBI burnout scores, as well as which individual variables were influential in contributing to burnout in EMS.FindingsThis study found that most EMS providers had high levels of depersonalization and medium levels of personal accomplishment and emotional exhaustion. Gender differences were found as they were differences based on agency type and response area.Research limitations/implicationsThe main limitation is the nature of sample recruitment. The use of social media for the recruitment of this type of study has not been done before. Furthermore, it is a convince sample. This issue has limited impact on the results and the ability to apply them more generally because despite the convince nature of this sample, the sample is similar to those used in other studies as well as reflect that national statistics on the make of this population. The second major limitation of this study is that it does not include job specific and organization specific factors that may contribute to burnout. The findings for the variables used in this study suggest that future works should encompass these variables as well.Practical implicationsThis study sets a clear foundation for further examination of US EMS providers and burnout. It helps to establish key ideas that can be followed up. Difference and key issues among US EMS providers need to be understood on a more comprehensive level before the assertion that they are similar to EMS providers worldwide. Ultimately, there is a need to develop better screening tools to assess burnout in EMS as well as to develop prevention and intervention programs based on clear empirical data.Social implicationsBurnout EMS provides are a harm to themselves as well as the organization that employ them. The cost of burnout EMS provider crosses over to patient care and provision of care.Originality/valueThis study is one of the first to examine such a large US-based sample of EMS providers using the MBI. Other studies have used smaller sample or other tools to assess burnout in providers
Supply chain governance: a conceptual model
Authors: Bonatto Franciele , Resende Luis Mauricio Martins de , Pontes Joseane 
Published: June 2021

Purpose
This paper aims to clarify ambiguous results from previous research on the relationship between contextual factors, trust and supply chain governance (SCG).

Design/methodology/approach
This study carried out a systematic literature review in 11 databases, with articles published until 2018. Afterward, this study conducted a thematic analysis in 60 articles to address the contextual factors, governance structures and trust approaches raised in previous research.

Findings
The thematic analysis revealed that seven contextual factors influence the choice of contractual and relational mechanisms in supply chains: relationship history, environmental uncertainty, perceived risk, perceived justice, asset specificity, power asymmetry and interdependence. The findings explained the ambiguous results of past research by proposing that contractual and relational governance are complementary and that the presence of trust (affective and competence-based) moderates the relationship between contextual factors and SCG.

Originality/value
This research advances the SCG literature by proposing trust (affective and competence-based) as a moderating variable that fosters governance mechanisms in supply chain relationships.
The influence of knowledge on wholesomeness, labelling and trust toward Muslim consumers purchase behaviour of Syubhah semi-processed food products
Authors: Rahman Reezlin Abdul , Zahari Mohd Salehuddin Mohd , Hanafiah Mohd Hafiz , Mamat Mohd Nor 
Published: June 2021

Purpose
The available research works dealing with Halal food are centrally concerned with the Halal certification, logistics, export market, consumer awareness and business ethics with minimal study explores Muslim consumers’ purchase behaviour of Syubhah semi-processed food. The purpose of this study is to investigate the relationship between Muslim consumers’ knowledge on the wholesomeness, labelling, trust and purchase behaviour of Syubhah semi-processed food.

Design/methodology/approach
The study respondents are Muslim consumers in the semi and rural areas. Through a self-administered survey, 780 usable responses were successfully collected. The study hypotheses were analysed using the partial least squares structural equation modelling. Mediation analyses were conducted, focusing on the effect of trust on the relationship between consumer knowledge on the wholesomeness, labelling and purchase behaviour of Syubhah semi-processed food.

Findings
This study confirms that lack of knowledge on the wholesomeness and labelling among the semi and rural Muslim consumers influences them to purchase the Syubhah semi-processed food. Trust significantly plays a significant mediation role on the consumer Syubhah semi-processed food purchase behaviour.

Originality/value
This study confirms there is lack of knowledge among the semi and rural Muslim consumers on Syubhah semi-processed food. Such pessimistic indications of Syubhah food products carry varying consequences and implications for Muslim consumers, Halal food producers and the relevant religious authorities.
Performance of spent garnet sand and used foundry sand as fine aggregate in concrete
Authors: Kanta Naga Rajesh , Ponnada Markandeya Raju 
Published: June 2021

Purpose
In the construction sector, river sand has turned into a costly material due to various reasons. In the current study, used foundry sand (UFS) and spent garnet sand (SGS) are used as a partial and full replacement to sand in concrete production.

Design/methodology/approach
The objective of the work is to develop non-conventional concrete by replacing river sand with a combination of UFS (constant 20Wt.% replacement) and SGS at various percentages (20, 40, 60 and 80 Wt.%).

Findings
Compared to conventional concrete, the 28 days compressive strength of non-conventional concrete (with UFS at 20% and spent garnet sand at 20%, 40% and 60% were 8.12%, 6.77% and 0.83% higher, respectively. The 28 days split tensile strength of non-conventional concrete (UFS at 20% and SGS at 20 and 40%) were 32.2% and 51.6% higher, respectively.

Research limitations/implications
It can be concluded that 60 Wt.% of river sand can be combined replaced with 20 Wt.% UFS and 40 Wt.% SGS to produce good quality concrete whose properties are on par with conventional concrete.

Practical implications
The results showed that combined SGS and UFS can be used as a partial replacement of river sand in the manufacturing of concrete that is used in all the applications of construction sector such as buildings, bridges, dams, etc. and non-structural applications such as drainpipes, kerbs, etc.

Social implications
Disposal of industrial by-product wastes such as SGS and UFS affects the environment. A sincere attempt is made to use the same as partial replacement of river sand.

Originality/value
Based on the literature study, no work is carried out in replacing the river sand combined with SGS and UFS in concrete.
Career Concerns and Financial Reporting Quality*
Authors: Pae Suil 
Published: June 2021

ABSTRACTManagerial career concerns could affect firm efficiency through financial reporting quality, but this important link has received relatively little attention in the literature. The present study examines this link by developing a model that has the following elements. A risk‐neutral manager provides effort to increase the market value of the firm and to favorably influence the market assessment of the manager's ability. Depending on the magnitude of career concerns, the manager either underinvests or overinvests effort relative to an efficiency‐maximizing level. The analysis identifies conditions under which higher‐quality reporting induces the manager to invest more effort. Under these conditions, the model is extended to a setting in which the manager also chooses the quality of financial reporting at some cost. In doing so, managers seek to reduce distortion in their effort investment. The equilibrium reporting quality and effort investment are determined by a trade‐off between them. In the presence of high uncertainty about the firm's future cash flows, if the manager's career concerns exceed a threshold the manager underinvests in reporting quality and overinvests effort. The empirical implication is a negative relation between managerial career concerns and financial reporting quality. To a large extent, this is consistent with findings in prior empirical studies. Thus, the present study offers a theoretical explanation for the empirical findings as an equilibrium outcome.
Prescribing drugs of dependence in dentistry: a review of legal and regulatory considerations
Authors: Johnstone M , Teoh L , Holden ACL 
Published: June 2021

ABSTRACTThe misuse of drugs of dependence is a major public health issue in Australia, and prescribing of these medications by dentists has increased in recent years. While there has been much focus on the appropriate indications and clinical use of these medicines in dental practice, the legal requirements of prescribing are equally important. Dental practitioners need to be aware of their legal obligations, as inappropriate prescription practices may lead to regulatory or criminal prosecution. Although dentists hold registration through the National Scheme and there is nationally standardised scheduling of drugs in Australia, the legislation governing drug laws differs for each state and territory, especially when prescribing drugs of dependence. This article summarises the legislation governing the prescription of drugs of dependence in Australia that is relevant to dental practice, providing insights into how dentists might contribute to the appropriate, safe and legal use and management of these medications.
Associations of cannabis use frequency and cannabis use disorder with receiving a substance use screen and healthcare professional discussion of substance use
Authors: Moore John R. , DiNitto Diana M. , Choi Namkee G. 
Published: June 2021

AbstractBackground and ObjectivesScreening, brief intervention, and referral to treatment (SBIRT) can reduce substance use, but receipt of these services by those who use cannabis frequently and have cannabis use disorder (CUD) remains unexplored. We examined cannabis use frequency and CUD's associations with the odds of receiving a substance use screening and a healthcare professional discussion among those who used healthcare services.MethodsData came from the 2015–2019 National Survey on Drug Use and Health (N = 214,505 aged 18+). Among adults who used cannabis and attended healthcare settings in the past year (N = 36,374), multivariable logistic regression analysis was used to examine associations of cannabis use frequency and CUD with receiving a substance use screen and substance use discussion by a healthcare professional.ResultsCannabis use frequency was associated with higher odds of receiving a screen (adjusted odds ratio [AOR] = 1.27, 95% confidence interval [CI] = 1.14–1.41 for 300+ days of use) and a discussion among those screened (AOR = 1.83, 95% CI = 1.60–2.09 for 300+ days of use). CUD was not associated with receiving a screen, but it was positively associated with receiving a discussion among those screened (AOR = 1.22, 95% CI = 1.08–1.39). Nonmedical users were less likely to have a discussion among those screened and not screened.Discussion and ConclusionsFindings indicate disparities in screening and discussion of substance use with patients, especially between medical and nonmedical users.Scientific SignificanceStudy findings provide novel insight into differences in the reach of SBIRT services among adult cannabis users.
