Soft power and soft disempowerment: Qatar, global sport and football’s 2022 World Cup finals
This paper examines the critical role of global sport within Qatar’s international strategy, most notably through the successful bid to stage the 2022 football World Cup. Our discussion draws particularly on interviews with key stakeholders in the Qatari sport system, as well as fieldwork in Qatar and the analysis of relevant documents and secondary materials. The paper is separated into five main parts. First, we set out our theoretical framework, which draws on the concepts of globalization and soft power; to assist in the analysis of Qatar’s engagement with global sport, we introduce the two further concepts of ‘glocal consciousness’ and ‘soft disempowerment’. Second, we provide the reader with background information on Qatar and Qatari sport. Third, we discuss three key themes that emerged mainly from our interviews on Qatar and global sport: exhibiting Qatar’s supremacies as a microstate; the pursuit of peace, security and integrity; and confronting national health crises. Fourth, we explore issues of soft disempowerment and reputational risk with regard to these three themes and, in particular, critical international comment surrounding Qatar’s hosting of the 2022 World Cup. Fifth, we conclude by arguing that Qatar’s soft disempowerment, although damaging in the short term, leaves the door open for the state to respond in a positive manner, regenerating its soft power capabilities in the process

Sulfur promotion in Au/C catalyzed acetylene hydrochlorination
The formation of highly active and stable acetylene hydrochlorination catalysts is of great industrial importance. The successful replacement of the highly toxic mercuric chloride catalyst with gold has led to a flurry of research in this area. One key aspect, which led to the commercialization of the gold catalyst is the use of thiosulphate as a stabilizing ligand. This study investigates the use of a range of sulfur containing compounds as promoters for production of highly active Au/C catalysts. Promotion is observed across a range of metal sulfates, non-metal sulfates, and sulfuric acid treatments. This observed enhancement can be optimized by careful consideration of either pre- or post-treatments, concentration of dopants used, and modification of washing steps. Pre-treatment of the carbon support with sulfuric acid (0.76 m) resulted in the most active Au/C in this series with an acetylene conversion of ≈70% at 200 °C
