“…However, this branch of the moiré theory remained for many years less widely known and less understood than its periodic or repetitive counterpart: Less widely known because moiré effects between aperiodic or random structures are less frequently encountered in everyday’s life, and less understood because these effects did not easily lend themselves to the same mathematical methods that so nicely explained the classical moiré effects between periodic or repetitive structures…”

“…Many OECD countries are presently recording inflows of less than 25% of what they received just two years ago. …”

“…Socio-economically disadvantaged students are less likely to enjoy orderly classrooms than advantaged students. …”

“…The common wisdom is that children are the best learners because they haven't become too set in their ways, and that the older people get the less adept at learning they become. Don Prince shares stories that seem to prove otherwise…”

“…Looks at the relationship between economic power and the digital world, encouraging readers to fight back against the monopolies that are making the Internet less democratic…”

“…Increases in educational attainment benefit the public because more highly educated people tend to pay more in taxes, are less likely to use social support programs, and are less likely to commit crimes. …”

“…Acclaimed as one of the “truly innovative” poets of her generation by Maud Ellmann, Sedgwick’s work as a poet is, perhaps, less well known, but is no less compelling than her ground-breaking trilogy of queer theoretical texts: Between Men: English Literature and Male Homosocial Desire, Epistemology of the Closet, and Tendencies…”

“…However, in most countries, information about private energy innovation is much less readily available and less reliable than that for the public sector. …”

“…In addition, countries with higher employment protection have both less inward and less outward FDI, and there is some evidence that more complex regulatory procedures reduce inward FDI…”

“…Most-Favoured-Nation (MFN) clauses link investment agreements by ensuring that the parties to one treaty provide treatment no less favourable than the treatment they provide under other treaties in areas covered by the clause. …”

“…The results also indicate that students with low reading achievements are not only less likely to remain in school; they are also less likely to return to school once they have left school. …”

“…This means that transport should be efficient, but at the same time make less demand on the environment through less use of resources, through recycling and reuse of materials, and through embracing a life cycle perspective..…”

“…This tension is intensifying in the internet age, in which the expensive production of journalistic content is less and less taken for granted. This updates the state's duty to ensure media pluralism, for example by organizing a public service system or other promotional measures, and to carry out active public relations work. …”
