Abstract
Here, we examine the challenges to democratization in Bahrain, with a particular focus on how the recent 2011 Uprising has resulted in a deepening of authoritarianism. It is argued that the recent unrest has brought into sharp relief the absence of “quality” democracy in Bahrain, and that any form of democratic transition is dependent on the will of a conservative Al Khalifa-Saudi nexus. While the pro-democracy movement may have prompted minor concessions on the part of the government, the extent of the popular mobilization triggered the Al Khalifa regime’s authoritarian reflex, and they have reacted to throttle the Uprising by putting in place legislative, ideological, and political barriers to reform, which points not only to a current de-democratization, but also a lack of future democratization. In addition to arguing for the post-2011 undoing of democracy in Bahrain, this paper also points to two major barriers to future democratization; (1) a conservative, post-Independence Al Khalifa-Saudi coalition assisted by large military resources (2) protracted communal tension brought about by the government’s instrumentalization of sectarianism.

The authors examine the effect of climate risk on accounting conservatism for a sample of listed companies operating in 26 developing countries.
Abstract
Purpose
The authors examine the effect of climate risk on accounting conservatism for a sample of listed companies operating in 26 developing countries.
Design/methodology/approach
The authors employ the Climate Risk Index (CRI) developed by Germanwatch to capture the severity of losses due to extreme weather events at the country level. The authors use different approaches to measure firm-level accounting conservatism.
Findings
The authors find that greater climate risk leads to a lower level of accounting conservatism. The results hold even after using different estimation methods.
Research limitations/implications
Although the authors' analysis is limited to the period 2007–2016, it could be helpful for standard setters such as International Accounting Standards Board (IASB) and International Sustainable Standards Board (ISSB) as they may consider the potential effect of climate risk in their international standards.
Practical implications
The negative impacts of climate risk on the quality of financial reporting as proxied by accounting conservatism could trigger regulators and standard setters to require disclosure of information relating to climate risks and to incorporate climate-related risks in their risk management systems. In addition, for policymakers, incorporating accounting conservatism as a financial quality reporting standard could help promote greater transparency, accuracy and reliability in financial reporting in the context of climate risk.
Originality/value
The authors add to the literature on international differences in accounting conservatism by showing that climate risk significantly affects unconditional and conditional conservatism. The authors' results provide fresh evidence of the dark side of climate change. That is, climate risk is shown to decrease financial reporting quality.

Abstract
Purpose
This research aims to examine the role of green intellectual capital (GIC) dimensions in promoting sustainable healthcare as reflected by sustainable performance. The mediating effect of green absorptive capacity (GAC) and moderating role of environmental turbulence were also explored.
Design/methodology/approach
Structural equation modeling was utilized for hypotheses testing of a survey data set of 387 at healthcare organizations operating in Iraq. The data were collected using purposive sampling with expert judgment from senior managers and professionals.
Findings
Contrary to previous studies, the findings showed that only green human and relational capitals predict green performance and only green human capital predicted economic performance. GAC was related to green human capital, green structural capital and performance, and played a significant mediating role on the relationships.
Research limitations/implications
Even though the research was limited to one region of a single country, Iraq, GAC can be modified by managers to enhance GIC for sustainable healthcare performance. This action must be viewed in terms of the future timing of the impact while managers display strong conviction for sustainability commitment. Managers will find GRC least associated with performance, but that GIC dimensions work best in unison.
Originality/value
The examination of GIC with GAC as moderated by environmental turbulence contributes nascent theoretical insights in sustainable healthcare.

Abstract
Purpose
The purpose of this paper is to investigate the effects of green tea extract on kidney function tests, in male rats that received different doses of acrylamide (AA).
Design/methodology/approach
Animals were dispensed at random to one of the following treatments: group 1 served as control, whereas groups 2, 3 received seven, 14 mg/100 g B.W/day of AA, respectively, in drinking water for 15 and 30 days. Group 4 received green tea 1.5 percent concentration and groups 5, 6 received seven, 14 mg/100 g B.W/day in a mixture with green tea for 15 and 30 days.
Findings
Serum urea and creatinine significantly increase with AA. However, Total protein, albumin and A/G ratio showed significant drop in all treated groups when compared with control. Supplementation of rats with antioxidant (green tea) enhanced the general health condition, reduced the severity of genotoxic effect and the alteration in blood and serum parameters produced by AA.
Practical implications
The authors suggest that green tea may deliver a cushion for long therapeutic option against toxins-induced nephrotoxicity without damaging side effects.
Originality/value
The study uses green tea as a natural antioxidant source. Epigallocatechin-3 gallate is the most plentiful catechin preserved in green tea and a high source of flavonoids. Flavonoids are a group of phenolic products of plant metabolism with high antioxidant properties to reduce nephrotoxicity without side effects.

Abstract
Purpose
English as a foreign langauge (EFL) students find it difficult to apply the theoretical knowledge they acquire on translation in the practical world. Therefore, this study explored if training in pretranslation techniques (PTTs) (syntactic parsing) as suggested by Almanna (2018) could improve the translation proficiency of Yemeni EFL students. Moreover, the study also assessed which of the PTTs the intervention helped to develop.
Design/methodology/approach
The study adopted a primarily experimental pre- and posttests research design, and the sample comprised of an intake class with 16 students enrolled in the fourth year, Bachelor in Education (B.Ed), Hadhramout University. Six participants were also interviewed to gather the students' perceptions on using PTTs.
Findings
Results showed that students' performance in translation developed significantly (Sig. = 0.002). All the six PTTs showed development, though subject, tense and aspect developed more significantly (Sig. = 0.034, 0.002, 0.001 respectively). Finally, the study reported students' positive perceptions on the importance of using PTTs before doing any translation tasks.
Originality/value
One of the recurrent errors that can be noticed in Yemeni EFL students' production is their inability to transfer the grammatical elements of sentences from L1 (Arabic) into L2 (English) or the visa versa. The researchers thought though translation is more than the syntactic transmission of one language into another, analyzing the elements of sentences using syntactic and semantic parsing can help students to produce acceptable texts in the target language. These claims would be proved or refuted after analyzing the experiment result of the present study.

Abstract
Purpose
The study aims to discuss the special needs-centric information delivery as a new genre of the academic library services. It also sheds light on the assistive technology used to help blind or visually impaired (BVI) students to access the available digital contents and use online services conveniently. A particular emphasis placed on gaining some insights into BVIs’ perceptions towards the orientation and assistance offered by the access service librarians, as well as any experience in using assistive educational technology for reading and information access.
Design/methodology/approach
The authors used semi-structured interview survey to gather the necessary data from 35 BVI university students drawn from the Special Needs Services (SNS) Unit at the UAE University. The interview was concerned with use of library e-resources and online services for doing their assignments, easy-to-use facilities to access the e-resources and main challenges facing them in communicating with the librarians.
Findings
The findings revealed that the BVI students considered that the university library does not answer their needs for getting access to digital content and using online services adequately.
Practical implications
The Main Library should cooperate closely with the SNS Unit to get the most benefits from their experience in the BVI-devoted services to develop an efficient library information discovery and delivery to this student group.
Originality/value
There is scarcity of scholarly studies on the pedagogical and information acquisition challenges facing the BVI university students in the UAE higher education. This is the first research study that tackles the experience of the BVI students in using the academic library.

Abstract
Purpose
The integration between production scheduling and maintenance planning is attracting the attention of planners in the manufacturing sector with the increase in global competitiveness. Researchers have developed various methodologies to optimize integrated decisions in planning and scheduling, including mathematical modeling under different conditions. This paper considers the simultaneous scheduling of production and maintenance activities with the objective of minimizing the expected total tardiness cost on a single machine (production line).
Design/methodology/approach
Scheduling in these two types of activities, production and maintenance, are traditionally done independently, causing conflicts between the two functional areas. To eliminate or at least reduce conflicts, the scheduling of both activities can be done simultaneously with the objective of meeting due dates and maintaining maximum machine availability. In this paper, a mathematical model for an integrated problem is developed and demonstrated by an example.
Findings
The proposed integrated model shows a high potential for significant improvements in performance with respect to the cost of tardiness in delivery and machine availability. This is demonstrated by an example showing an average savings of approximately 40%.
Originality/value
This substantial saving is owed to the integration of two important decision-making processes in manufacturing systems. Although the integrated problem is complex and difficult to solve, the fact that it is savings driven makes the problem of interest to researchers and practitioners in manufacturing.

Abstract
Purpose
This study aims to look at how financial technology (FinTech) companies adhere to sustainable standards in contrast to their counterparts. Following the validation of its new sustainability index, this study looks into the impact of sustainability on the stock performance of FinTech companies.
Design/methodology/approach
To efficiently test the hypotheses, sample has been collected from the Bloomberg of all FinTech and non-FinTech companies from the USA. The final sample comprises 1,712 company-year observations over the investigation period 2010–2019. The methodology entails ordinary least squares regressions and generalized panel methods of moments (GMM).
Findings
The results suggest that the developed sustainability index is a valid proxy for sustainability measures and directly relates to stock performance. Besides, the evidence indicates that non-FinTech companies display superior sustainability and stock performance compared to FinTech companies. The present results corroborate with stakeholder theory, which implies that quality sustainability performance will alleviate the agency issue and safeguard the shareholders’ interest.
Research limitations/implications
Despite the fact that it presents the limitation of not considering other dimensions of financial performance, this research is important as it highlights the sustainability practices by the FinTech and non-FinTech companies, offering insights to researchers, policymakers, regulators, financial reports users, investors, environmental union, employees, clients and society.
Originality/value
This paper is novel because it is unique in evaluating the sustainability practices in FinTech and non-FinTech firms.

Abstract
Purpose
The construction industries at present are focusing on designing sustainable concrete with less carbon footprint. Considering this aspect, a Fibre-Reinforced Geopolymer Concrete (FGC) was developed with 8 and 10 molarities (M). At elevated temperatures, concrete experiences deterioration of its mechanical properties which is in some cases associated with spalling, leading to the building collapse.
Design/methodology/approach
In this study, six geopolymer-based mix proportions are prepared with crimped steel fibre (SF), polypropylene fibre (PF), basalt fibre (BF), a hybrid mixture consisting of (SF + PF), a hybrid mixture with (SF + BF), and a reference specimen (without fibres). After temperature exposure, ultrasonic pulse velocity, physical characteristics of damaged concrete, loss of compressive strength (CS), split tensile strength (TS), and flexural strength (FS) of concrete are assessed. A polynomial relationship is developed between residual strength properties of concrete, and it showed a good agreement.
Findings
The test results concluded that concrete with BF showed a lower loss in CS after 925 °C (i.e. 60 min of heating) temperature exposure. In the case of TS, and FS, the concrete with SF had lesser loss in strength. After 986 °C and 1029 °C exposure, concrete with the hybrid combination (SF + BF) showed lower strength deterioration in CS, TS, and FS as compared to concrete with PF and SF + PF. The rate of reduction in strength is similar to that of GC-BF in CS, GC-SF in TS and FS.
Originality/value
Performance evaluation under fire exposure is necessary for FGC. In this study, we provided the mechanical behaviour and physical properties of SF, PF, and BF-based geopolymer concrete exposed to high temperatures, which were evaluated according to ISO standards. In addition, micro-structural behaviour and linear polynomials are observed.
