Does information disclosure reduce stock price volatility? A comparison of Islamic and conventional banks in Gulf countries
Authors: Azrak Tawfik , Saiti Buerhan , Kutan Ali , Engku Ali Engku Rabiah Adawiah 
Published: August 2020

PurposeThe purpose of this paper is to investigate whether higher disclosure levels at both Islamic and conventional banks are associated with higher stock price volatility in the member countries of the Gulf Cooperation Council (GCC).Design/methodology/approachTo do this, the authors build a disclosure index (DI) for both types of banks and compare their transparency levels. After that, the authors evaluate the relationship between disclosure and stock price volatility for both conventional and Islamic banks (IBs) and include macro- and bank-level control factors to isolate the effect of disclosure from potentially confounding influences by employing panel data.FindingsThe author find that the significance of the DI on stock price volatility is economically negligible at both types of banks, suggesting that injecting more information into markets would raise stock price volatility only slightly and hence will not have much economically significant effect on stock price volatility in our sample countries. The authors discuss the policy implications of the findings.Originality/valueThe study fills the gap in the literature and assists in formulating appropriate regulation policies for corporate governance disclosure requirements. To the best of our knowledge, this is the first empirical study to investigate the impact of disclosure on reducing stock price volatility in the dual banking system of the GCC countries.

Purpose
In view of the intensive spread of Coronavirus disease 2019 (COVID-19) and in order to reduce the rate of spread of this disease; the objective of this article is to propose an approach to detect in real time suspect person of Coronavirus disease 2019 (COVID-19).

Design/methodology/approach
The ubiquitous computing offers a new opportunity to reshape the form of conventional solutions for personalized services according to the contextual situations of each environment. The health system is seen as a key part of ubiquitous computing, which means that health services are available anytime, anywhere to monitor patients based on their context. This paper aims to design and validate a contextual model for ubiquitous health systems designed to detect in real time suspect person of COVID-19, to reduce the propagation of this infectious disease and to take the necessary instructions.

Findings
This paper presents the performance results of the COVID-19 detection approach. Thus, the reduction of the COVID-19 propagation rate thanks to the real-time intervention of the system.

Originality/value
Following the COVID-19 pandemic spread, the authors tried to find a solution to detect the disease in real time. In this paper, a real-time COVID-19 detection system based on the ontological description supported by Semantic Web Rule Language (SWRL) rules was developed. The proposed ontology contains all relevant concepts related to COVID-19, including personal information, location, symptoms, risk factors, laboratory test results and treatment planning. The SWRL rules are constructed from medical recommendations.

Published: August 2020

PurposeThis study investigates the effect of digital technology adoption on labor demand in the Indonesian banking sector.Design/methodology/approachThis research uses bank-level survey data obtained from the Indonesia Financial Service Authority (OJK) for the period 2010–2017 using semiannual data. This research applies a panel data method using a fixed effect model.FindingsThis study results show that technology adoption affects labor demand significantly in all Commercial Bank Based on Business Activities (BUKU) levels of banks. Technology adoption tends to be a substitute for labor in BUKU I, BUKU II and BUKU III banks in the support and business units. In addition, technology adoption complements labor only in the business unit in BUKU IV banks.Research limitations/implicationsThis research uses a sample of only 40 banks at the regulatory levels of BUKU I, BUKU II, BUKU III and BUKU IV. These 40 banks account for more than 80% of the assets in the Indonesian banking sector.Originality/valueLiterature investigating the effect of the adoption of digital technology on labor demand in the banking sector is still rare in the Indonesian economy. Most of the previous research limited its area of study to the manufacturing industry. This research makes a vital contribution in measuring the adoption of digital technology and its effect on labor demand in the banking sector using the BUKU level classifications of banks.
Investigating the implementation of and accountability in PPPs: a case study in public water management
Authors: Mutiganda Jean Claude , Skoog Matti , Grossi Guiseppe 
Published: August 2020

PurposeThis study analyses how the implementation of PPPs to operate rural water infrastructures and deliver water to local population has led to a new accountability archetype.Design/methodology/approachThe archetype theory is used to analyse the process of implementing PPPs as a new archetype and setting up systems and structures of accountability between contracting parties. The empirical part of the study is based on extensive document analysis in an East African country. Documents analysed are from governmental sources, UNICEF and the World Bank and cover a period from 1998 to early 2019.FindingsThe process of implementing PPPs was revolutionary at the national level and evolutionary at micro levels. The sequence of the change process moved from central to peripheral. The linearity followed a reorientation track strategy. Setting up systems and structure of accountability was evolutionary, peripheral to central following the reorientation strategy. National authorities reacted proactively to comments and suggestions from international donors and local population. However, not all districts have fully implemented PPPs in their rural water sector. The structure of accountability at the local level, however, still suffers from logistical and professional capacity constraints.Research limitations/implicationsEmpirical findings cannot be generalised to other situations, but the theoretical framework used in this study can be applied elsewhere.Practical implicationsGiving priority to hearing from end users themselves before designing and implementing policies that intend to respond to specific local needs is recommended.Originality/valueThis study explains the ways in which micro-organisational change can lead to revolutionary archetypes such as PPPs, whereas the implementation of systems and the structure of accountability at inter-organisational level remain evolutionary.
Population growth, income growth and savings in Ghana
Authors: Gatsi John Gartchie , Owusu Appiah Michael 
Published: August 2020

PurposeThe study explores the relationship among economic growth, population growth, gross savings and energy consumption over the period 1987– 2017.Design/methodology/approachThe autoregressive distributed lag (ARDL) bounds test approach by Pesaranet al.(2001) was employed to investigate variables for the study.FindingsIn the key findings, both gross savings and population growth negatively affect economic growth. However, energy consumption has positive impact on economic growth.Practical implicationsThese findings call for policy portfolios to address the impacts of gross savings and population growth on economic development. In particular, the financial sector needs to be revamped to be more efficient in channeling funds from the surplus units to the deficit units. It is recommended that investment be made in financial and technological innovation to provide efficient access to credits and other financial products even though individual savings may not move with economic growth.Originality/valueMany studies have explored the nexus between savings and economic growth without considering population growth and energy consumption. In this study, the relationship among savings, economic growth, population growth and energy consumption provide additional knowledge in policy formulation.
A systematic review of halal supply chain research: to where shall we go?
Authors: Indarti Nurul , Lukito-Budi Andy Susilo , Islam Azmi Muhammad 
Published: August 2020

Purpose
This study aims to explore existing study trends in the halal supply chain (HSC) field as an extension of supply chain studies. Upon examining multiple journal ranks and citation profiles, these trends cover research themes, methodologies, settings (country and data analysis level) and their interactions.

Design/methodology/approach
The study followed a systematic, mixed-method review to pinpoint the HSC research themes. The Publish or Perish software, with specific criteria, was used to retrieve and filter 87 HSC articles from 2009 to 2019 from the Google Scholar database. Then, an input–process–output framework was used to classify and discuss potential future research.

Findings
This study concludes that HSC research is still in early development. Five themes consisting of 24 different topics were found: the engagement process, quality control assurance, critical success factors, the production and distribution process and HSC operations support. Most of the HSC studies followed conceptual and qualitative interview methods, with special reference to Muslim-majority countries and organization-level analysis. Within one decade, the number of HSC publications grew significantly, though their presentation is mainly in unindexed journals and their citation rate is low. This study thus proposes three main future HSC research points: HSC consequences, processes and antecedents.

Practical implications
Possible practical implications can be expected from the authors’ proposed empirical studies as guidelines to formulate and promote HSC implementation.

Originality/value
No comprehensive HSC research review exists in the literature. This study intends to fill this void by charting cumulative knowledge and proposing a roadmap for future research endeavors.
The impact of the use of employee functional flexibility on patient safety
Authors: Salvador Rommel O. , Gnanlet Adelina , McDermott Chris 
Published: August 2020

PurposeThe purpose of this study is to examine the effect of the use of unit-level functional flexibility on one particular patient outcome, unit-acquired pressure ulcers, and the potential moderating influences of coworker support and workload.Design/methodology/approachThis study uses an archival approach, examining data from 68 hospital units.FindingsThe results indicate that a unit's higher use of functionally flexible nurses in one-quarter was associated with a higher number of pressure ulcers among the unit's patients the following quarter. This detrimental effect was significantly diminished when coworker support within the unit was high. Unit-level nurse workload did not have any moderating influence.Research limitations/implicationsOne of the scholarly contributions of this study is that it links greater use of functionally flexible employees to a negative patient safety outcome at the unit level. As most of the variables used in the study were archival measures, future research could examine the replicability of these findings using other indicators and measures.Practical implicationsBeyond healthcare settings, the results prompt managers in industries where there has been growing use of functional flexibility (e.g., banking) to think about the associated unintended negative consequences. That said, the results also point to coworker instrumental support as a means by which to mitigate negative outcomes.Originality/valueAlthough functional flexibility has been shown to positively correlate with a number of organizational performance indicators, this is one of the very few studies that has examined its negative consequences, particularly on patient safety.
The fading of fear effects due to coral degradation is modulated by community composition
Authors: Ferrari Maud C. O. , McCormick Mark I. , Fakan Eric , Barry Randall , Chivers Douglas P. 
Published: August 2020

AbstractAn increasing number of coral reefs throughout the world have become degraded as a result of climate change. This degradation has resulted in a significant decline in local biodiversity. Studies have shown that some fishes (non‐responders) within these altered habitats are not able to adequately access olfactory cues, specifically chemical alarm cues that are crucial in mediating predation risk.We propose that the inability to access this crucial information is a potential mechanism for increased mortality of these species under natural conditions. However, we posit that the presence of certain key species (responders that are unaffected by degradation) may buffer the handicap of non‐responders by providing an alternate source of information.To explore this hypothesis, we investigated if a high ratio of responders to non‐responders could mitigate the impact of information loss for the affected species. Using mesocosms, we manipulated the ratio of two damselfish species,Pomacentrus chrysurus(responder) andP. moluccensis(non‐responder), to determine if community composition can be predictive of information transfer about predation threats in nearby non‐responder individuals.Our results indicate that, in degraded environments, the magnitude of fear effects seen inP. moluccensisexposed to a predator was proportional to the number ofP. chrysuruspresent and consumed by the predator in the community. This indicates thatP. chrysurusbecame the only functional source of predation‐related information forP. moluccensisin degraded habitats. These results contrasted with those from live coral environments, where all individuals exhibited fear effects, regardless of community composition.Our study provides evidence that the presence of non‐affected species in the community provides a potential mechanism allowing increased resilience by affected species, therefore providing another example of the way biodiversity affects ecological resilience of species in changing ecosystems.A freePlain Language Summarycan be found within the Supporting Information of this article.

Published: August 2020

SummaryWe analysed a widely used barcode, the V9 region of the 18S rRNA gene, to study the effect of environmental conditions on the distribution of two related heterotrophic protistan lineages in marine plankton, kinetoplastids and diplonemids. We relied on a major published dataset (Tara Oceans) where samples from the mesopelagic zone were available from just 32 of 123 locations, and both groups are most abundant in this zone. To close sampling gaps and obtain more information from the deeper ocean, we collected 57 new samples targeting especially the mesopelagic zone. We sampled in three geographic regions: the Arctic, two depth transects in the Adriatic Sea, and the anoxic Cariaco Basin. In agreement with previous studies, both protist groups are most abundant and diverse in the mesopelagic zone. In addition to that, we found that their abundance, richness, and community structure also depend on geography, oxygen concentration, salinity, temperature, and other environmental variables reflecting the abundance of algae and nutrients. Both groups studied here demonstrated similar patterns, although some differences were also observed. Kinetoplastids and diplonemids prefer tropical regions and nutrient‐rich conditions and avoid high oxygen concentration, high salinity, and high density of algae.

AbstractAimTo determine clinical risk factors in patients with PI‐RADS 3 lesions and prostate‐specific antigen (PSA) < 10 ng/mL.MethodsIn this prospective study, all patients underwent multiparametric magnetic resonance imaging. Following the 2‐5 core fusion‐targeted biopsy, standard 12‐core prostate biopsy was performed in each patient (combined biopsy). The cutoff values were calculated with receiver‐operating characteristic analysis. First, univariate logistic regression analysis was used to evaluate the relationship between total eight parameters and prostate cancer. Subsequently, multiple logistic regression analysis was performed to the parameters associated with prostate cancer.ResultsTwo hundred and eighty‐eight patients were included in the study. Some clinical parameters are determined to be significant in univariate and multiple logistic regression analyses, including PSA, free/total PSA ratio, PSA density (PSA/total prostate volume), positive family history of PCa, and PI‐RADS 3 lesion diameter. Patients were classified between 0 and 5 according to the number of risk factors. While the risk of cancer was 7.1% in patients with one or less risk factors, the PCA rate was 45.2% among patients with all risk factors.ConclusionIn patients with PI‐RADS 3 lesion and PSA < 10 ng/mL, histopathological results of biopsy can be estimated with higher accuracy using some clinical parameters.

AbstractAimThe aim of the study was to compare the therapeutic strategies and prognostic factors of patients with primary intestinal diffuse large B‐cell lymphoma (PI‐DLBCL).MethodsA total of 50 PI‐DLBCL patients who accepted standard first‐line treatment at National Cancer Center in China were included in this retrospective study. Survival analysis was performed to evaluate the prognostic risk factors.ResultsThe 3‐year overall survival (OS) and 3‐year progression‐free survival (PFS) for the entire group were 76.0% and 65.9%, respectively. Univariate analysis showed that B symptom, advanced Lugano stage, elevated LDH status, poor ECOG PS and immunochemotherapy alone were significantly correlated with a poor PFS. Elevated LDH status, poor ECOG PS, advanced Lugano stage, high IPI score and immunochemotherapy alone were significantly correlated with a poor OS. Multivariate analysis revealed that ECOG PS (P= 0.035; HR = 0.233; 95% CI, 0.060–0.905), LDH level (P = 0.010; HR = 0.223; 95% CI, 0.072–0.693) and surgery (P = 0.002; HR = 5.584; 95% CI, 1.883–16.563) were independent prognostic factors for OS. LDH level (P = 0.035; HR = 0.210; 95% CI, 0.049–0.894) and surgery (P = 0.003; HR = 6.410; 95% CI, 1.903–21.593) were independent risk factors for PFS in PI‐DLBCL. R‐CHOP immunochemotherapy combined surgery treatment was also associated with a lower rate of refractory/relapsed (R/R) disease (P = 0.004). Furthermore, stratified analysis revealed that partial resection or radical resection combined with immunochemotherapy had no significantly difference which affect OS (P = 0.338) and PFS (P = 0.207).ConclusionR‐CHOP immunochemotherapy plus surgery was associated with a superior prognosis compared with R‐CHOP alone in Chinese PI‐DLBCL population.

AbstractBackgroundB‐cell acute lymphoblastic leukemia (B‐ALL) is the most commonly diagnosed childhood malignancy worldwide and is especially common in Mexico. Additionally, the number of cases has increased in recent years. Thus, it is very important to develop molecular strategies to diagnose leukemia. The aim of this study was to investigate MYB expression and to determine its impact on the diagnosis of B‐ALL.MethodsWe analyzed the B‐ALL gene expression profile by microarray data mining. Bioinformatics analysis was performed to identify the genes that are overexpressed in leukemia. We determined that MYB was highly expressed in leukemia. Then, we validated MYB expression in 70 patients with B‐ALL and in 16 healthy controls (HCs) using qRT‐PCR. The results were statistically analyzed using the Kolmogorov‐Smirnov Z test, Mann‐Whitney U test, receiver operating characteristic curves, and the Youden index.ResultsThe microarrays showed that MYB was overexpressed in B‐ALL patients with a fold change of 57.8728 and a P value of 2.56−195. MYB expression showed great variability among the patients analyzed. However, compared to the HCs, the B‐ALL patients had a P value < .0001, an area under the curve of 0.813, and a Youden index of 1.46, indicating the statistical significance.ConclusionMYB expression in B‐ALL cells could be a potential molecular marker for childhood leukemia.
Informed consent for controlled human infection studies in low‐ and middle‐income countries: Ethical challenges and proposed solutions
Authors: Vaswani Vina , Saxena Abha , Shah Seema K. , Palacios Ricardo , Rid Annette 
Published: August 2020

AbstractIn controlled human infection studies (CHIs), participants are deliberately exposed to infectious agents in order to better understand the mechanism of infection or disease and test therapies or vaccines. While most CHIs have been conducted in high‐income countries, CHIs have recently been expanding into low‐ and middle‐income countries (LMICs). One potential ethical concern about this expansion is the challenge of obtaining the voluntary informed consent of participants, especially those who may not be literate or have limited education. In some CHIs in LMICs, researchers have attempted to address this potential concern by limiting access to literate or educated populations. In this paper, we argue that this practice is unjustified, as it does not increase the chances of obtaining valid informed consent and therefore unfairly excludes illiterate populations and populations with lower education. Instead, we recommend that investigators improve the informed consent process by drawing on existing data on obtaining informed consent in these populations and interventions aimed at improving their understanding. Based on a literature review, we provide concrete suggestions for how to follow this recommendation and ensure that populations with lower literacy or education are given a fair opportunity to protect their rights and interests in the informed consent process.
