The objective of this paper is to analyse how contractual stabilization devices have evolved since the late 1990s, based on a survey of 20 countries and a review of the literature and evidence on stabilization clauses. Although fiscal stability is a commonly cited attribute of a desirable upstream petroleum regime, one of the commonly observed features of existing regimes is the lack of stability. The paper studies the major triggers that push host governments to revise the fiscal terms to which they originally agreed with investors; amongst various economic and political factors, one of the obvious drivers is the oil price. Chasing the price of oil, however, is a burdensome and inefficient strategy, as oil is an internationally traded commodity where short-term price volatility is the norm. The paper's three broad conclusions include: First, classical stabilization models have not been successful in practice; Second, the more modern clauses are more likely to treat changes in fiscal terms symmetrically, and may be equally beneficial to governments and oil companies; Third, modern stabilization clauses can allow policymakers to consider the overall tax system and its impact on revenue and growth, without worrying about the specific impact on the oil and gas sector, and without penalizing investors in the sector. Fiscal stability clauses in developing countries will remain a key feature of contractual agreements and oil and gas laws for years to come. However, the effectiveness of the more modern clauses in achieving the desired outcome remains as questionable as that of previous stability models, particularly in countries which continue to lack the administrative capability to enforce these mechanisms, and where government policy in general and investment laws and the judiciary in particular lack credibility.

The role of the community pharmacist has evolved to include the provision of more clinical services for patients. Those people who have stable chronic conditions will be managed in community pharmacies. This qualitative study used semi-structured in-depth interviews to understand the potential of providing additional patient-centred care for patients with stable chronic conditions in community pharmacies and identify potential limitations of this approach. Participants were recruited from Welsh Government, Local Health Boards (LHBS), Community Pharmacy Wales (CPW) and the Royal Pharmaceutical Society Wales (RPSW). The interviews were audio-recorded, transcribed verbatim, and analysed thematically. Eight interviews were conducted. The identified themes were as follows: (1) inconsistency and bureaucracy in commissioning pharmacy services; (2) availability of funding and resources; (3) disagreement and uncertainty about the contribution of the community pharmacy sector; (4) continuity of patient medical information and fragmented care; (5) accessibility, capacity and facilities in community pharmacy; (6) pharmacy education and clinical expertise, and (7) patient acceptability. It was clear that the potential benefit of managing stable chronic diseases in community pharmacies was recognised; however, several limitations expressed by stakeholders of pharmacy services need to be considered prior to moving forward.

Telemedicine utilization increased overnight during this pandemic because of its ability to enhance access to oral healthcare, easily link to remote area, time management, low cost, etc. We aimed to identify the utilization of telemedicine among oral medicine practitioners in Saudi Arabia during COVID-19 pandemic and identify future impacts, potential challenges and barriers hindering the implementation of telemedicine.Methods: The present cross-sectional electronically self-administered supplement-based survey Supplement Based Survey study was conducted among different professional levels of oral medicine involving consultants, specialists, and residents. The supplement includes demographic data, the current use of telemedicine, participant's perspective on future implications, and potential barriers and limitations of telemedicine. Internal consistency was measured using Cronbach's alpha (α) to assess how closely related a set of items in our study.Results: Of the total (N = 75) oral healthcare professionals, 52% were male, 70.7% were Saudi, 45.3% were consultant, 42.7% had 1– 5 years of experience, 82.7% were practicing in urban areas, 93.3% stated COVID-19 affected their clinics, consultation was the major reason for the use of telemedicine before (50.7%) and during (72%) COVID-19 outbreak, 57.3% were communicating with their patients, 97.33% had not experienced any cyber risk, and 45% patients were satisfied with the telemedicine service; our data showed a high level of homogeneity (α = 0.82). The poor knowledge and training on telemedicine technologies may substantially (p < 0.05) impact the future implications of telemedicine in oral medicine practice.Conclusion: Telemedicine could be a useful adjunct for oral medicine practice, especially for remote diagnosis, consultation, referral, training and education. Our study emphasizes an urgent need to increase the awareness and education on how to utilize and practice telemedicine technologies among medical staff to maximize the efficiency.Keywords: awareness, barriers, COVID-19, oral medicine, telemedicine

In the context of achieving the new Sustainable Development Goals, revenue mobilization is a high priority in developing countries and in Sub-Saharan Africa, where governments' ability to tax remains limited. Using a unique revenue dataset spanning the period 1980-2010, we analyze three important tax reforms: the Large Taxpayers Unit (LTU), the Value Added Tax (VAT), and the Semi-Autonomous Revenue Agency (SARA). We propose an ex-post impact assessment of these tax reforms in SSA countries based on propensity-score matching methodology (PSM) and synthetic control method (SCM). VAT and SARA are found to have an unambiguously large and positive effect on non-resource taxes, while the impact of LTU is insignificant—LTU seems however an important precondition for the adoption of the first two reforms. We conclude also that VAT and SARA display some synergy, and their positive effects strengthen several years after their adoption.

Pharmacists stand alongside with other professionals in representing essential healthcare during health emergencies such as COVID-19 pandemic. The present study seeks to explore the behavior and attitude of community pharmacists across various pharmacies throughout this pandemic towards the safety of workplace environment for staff and patients. An online questionnaire has been prepared and distributed to 145 community pharmacies during March to May, 2020. The collected results and data showed that community pharmacists in Libya have a good knowledge and adherence to preventive and protective measures published by FIP, WHO and other health-related organizations to protect themselves and society from infection. The pharmacist role in educating and information provision of the current disease and its management is still going on regardless the pandemic. A negative evaluation to the government support during the pandemic is clear from participant's replies. In Conclusion, this study looks forward to disclosing the current activities undertaken across various community pharmacy settings concerning safety of the workplace environment for both staff and patients. A clear and relatively realistic picture of the extent of commitment and knowledge of pharmacists of the necessary aspects needed to deal with this pandemic within community pharmacies is suggested. The extent of community pharmacist's knowledge, readiness and speed of their response to such a pandemic have been identified.
