The new variety is remarkable in having four stamens, laterally folded leaves, a short peduncle, thick leathery petals, and a four-sided ovary with a sessile style. A key for the species of Rhizophora of the Andaman and Nicobar Islands is also pr...

In [16] it was investigated how one can work with style guides called “UI guidelines” in this article when designing user interfaces in commercial software development. The document explained what aspects style guides deal with on an abstract and a specific level related to the development process and the software product. During this research various problems related to the use of style guides...

Despite its pedagogical predominance during the last four decades, marketing scholars increasingly doubt the value of the 4Ps schema. As a prelude to a new precursory structural framework for marketing management, criticisms and previously proposed modifications of the 4Ps are reviewed briefly. Next, the basic premise of Hunt’s four explananda of marketing theory–that exchange is the core conce...

Sixty-five years after Turing first revealed the potential of systems with local activation and long-range inhibition to generate pattern, we have only recently begun to identify the biological elements that operate at many scales to generate periodic patterns in nature. In this Primer, we first review the theoretical framework provided by Turing, Meinhardt, and others that suggests how periodi...

There are two versions of type assignment in λ-calculus: Church-style, in which the type of each variable is fixed, and Curry-style (also called “domain free”), in which it is not. As an example, in Church-style typing, λx : A . x is the identity function on type A, and it has type A → A but not B → B for a type B different from A. In Curry-style typing, λx.x is a general identity function with...

National efforts to greatly reduce the number of uninsured Americans have made little progress for decades because achieving majority support for any one approach has proved to be impossible. While as authors we remain unreconciled on the best solution, we share the belief that federally supported state experimentation is a promising way to make progress. States should be allowed to try widely ...

The recent substantial advantages for the acquirement of such knowledge will, no doubt, spur the young hands ; and in future we expect very few men of this class will pass i...

Climate researchers are bouncing back in spite of fresh criticism of the IPCC management and are looking to understand catastrophic individual events.
