Density functional theory is employed to explore the binding of carbon dioxide and methane in a series of isoreticular metal “organic frameworks, with particular emphasis on understanding the impact of directly incorporated nitrogen and oxygen heteroatoms on the affinity of the ligand for CO2 and CH4. While the strongest binding sites for both CO2 and CH4 were found to be directly above the aromatic rings of the core of the ligand, the introduction of heteroatoms to the core systems was shown to significantly alter both the binding strength and preferred binding locations of CH4 and CO2. The presence of pyrazine rings within the ligand was observed to create new binding sites for both CO2 and CH4 and, in the case of CO2, severely reduce the binding strength or entirely eliminate binding sites that were prominent in the analogous carbocyclic ligands.
This Chapter addresses three questions: What is good quality university teaching? How can it be achieved? How can it be assessed? To address these questions we start by making a case for a multi dimensional, rich conceptualisation of teaching, drawing on a substantial body of higher education research that investigates what supports meaningful learning and on Lee Shulman TMs notion of pedagogical content knowledge TM to argue for a principled approach to the design of learning, teaching and the curriculum, which brings groups of students into productive relations with bodies of knowledge. Having established an evidence based conceptualisation of good quality teaching, we turn to contemporary policy efforts to assess the quality of university undergraduate teaching, arguing that globally the current landscape and languages of higher education are shaped by neoliberal discourses that position learning, teaching and curriculum as a technical rational matter. In this context, measuring quality by way of metrics TM requires the use of proxies for good teaching, which runs the risk of offering an impoverished definition of the quality of teaching in higher education that also privileges certain social groups.
Tourists found breaking the conditions of the pledge may be fined.There have been 239,102 pledges taken since the initiative was launched.Palau is not the only destination to ask tourists to sign a pledge, although it is the only one that stamps it on visitors passports.The pledges generally ask tourists to treat the destination with respect, not litter, follow local rules and avoid risky behaviour, The Post reports.With the exception of Palau, the pledges generally don threaten punishments or fines, but some listed behaviours may be against the law and therefore carry penalties of their own.Iceland, which has seen a massive surge in visitor numbers over the last few years, asks tourists to not venture off roads, to use approved parking spots and be safe while taking selfies in its Icelandic Pledge that has had close to 70,000 signatures since it was introduced in 2017.The Post tourists could sign the pledge online or at the airport.trying to speak to the honour code in tourists that are coming to Iceland, and we don want to forbid too much, she said. Much rather send the message in a benign way and ask people to join us in this venture to be responsible and preserve the beautiful nature of Iceland. Kokkarinen, the project manager at Visit Finland, said Finland pledge was to protect travellers visiting Finland and make them aware of these general rules and responsibilities visitors may not know about the different rules in nature areas, the pledge offers a way to guide them towards the respectful behaviour that is expected of them while visiting Finland, she told The Post..
