Tailoring Acidic Oxygen Reduction Selectivity on Single-Atom Catalysts via Modification of First and Second Coordination Spheres.

Abstract: Product selectivity in multielectron electrocatalytic reactions is crucial to energy conversion efficiency and chemical production. However, a present practical drawback is the limited understanding of actual catalytic active sites. Here, using as a prototype single-atom catalysts (SACs) in acidic oxygen reduction reaction (ORR), we report the structure-property relationship of catalysts and show for the first time that molecular-level local structure, including first and second coordination spheres (CSs), rather than individual active atoms, synergistically determines the electrocatalytic response. ORR selectivity on Co-SACs can be tailored from a four-electron to a two-electron pathway by modifying first (N or/and O coordination) and second (C-O-C groups) CSs. Using combined theoretical predictions and experiments, including X-ray absorption fine structure analyses and in situ infrared spectroscopy, we confirm that the unique selectivity change originates from the structure-dependent shift of active sites from the center Co atom to the O-adjacent C atom. We show this optimizes the electronic structure and *OOH adsorption behavior on active sites to give the present "best" activity and selectivity of >95% for acidic H2O2 electrosynthesis.

Accounting practice in the new millennium: is accounting education ready to meet the challenge?

Abstract: As the new century and millennium get underway it is appropriate to reflect upon, and plan for, expected changes in accounting practice and the implications of these changes for accounting education. This paper covers three broad topics. These are: • the future of business and accounting practice—a brief review of the predictions about how we will do business in the new century seems a necessary precursor to a discussion of changes in education; • in the light of expected changes in business, what skills will be required by the accountants of the future?; and • what are the implications for accounting education? Expected trends in business practice and the necessary skill set of accountants are reviewed in the light of recent literature from the United Kingdom, United States and Australia. These trends suggest that so-called ‘compliance’ work will form a diminished portion of accounting firms' revenues as technology means that even small businesses become more empowered with respect to their record-keeping needs. On the other hand, the main growth areas of accounting practice appear to lie in the fields of business advisory services. As such, future accountants will take on the role of ‘knowledge’ workers. Although a command of technology will be an important component of an accountant's skill set, of more significance will be skills in analysis, innovative problem solving, communication and client relations. Accounting educators need to anticipate the expected shift in accountants' skills and develop courses and teaching methods that are far more interdisciplinary and analytical in their orientation. This paper explores some ways in which this might be achieved and some of the challenges to effecting change in accounting education that will have to be overcome.

Will I Stay or Will I Go? Explaining Repatriation by Self-Initiated Expatriates

Abstract: Offering an integrated framework, we sought to explain why and how professionals who self-initiate expatriation repatriate. We measured host country “pull” and “push,” home country pull, “shocks,” ...

Victims’ perceptions of traditional and cyberbullying, and the psychosocial correlates of their victimisation.

Abstract: It is well recognised that there are serious correlates for victims of traditional bullying. These have been shown to include increased levels of depression, anxiety and psychosomatic symptoms, in addition to often severe physical harm and even suicide. Bullied students also feel more socially ineffective and have greater interpersonal difficulties, together with higher absenteeism from school and lower academic competence. In the emerging field of cyberbullying many researchers have hypothesised a greater impact and more severe consequences for victims because of the 24/7 nature and the possibility of the wider audience with this form of bullying. However, to date there is scarce empirical evidence to support this. This study sought to compare victims' perceptions of the harshness and impact of bullying by traditional and cyber means. The major findings showed that although students who had been victimised by traditional bullying reported that they felt their bullying was harsher and crueller and had mor...
