The potential function of Lippincott and Schroeder for linear hydrogen bond has been re-examined and extended to nonlinear hydrogen bond. The parameters originally introduced to the potential function by Lippincott and Schroeder have been determined from the structural parameters such as 0.. .Odistance 0-H bond distance, H.. .O distance and HOO angle. Thevalidity of harmonic oscillator appr...

In the title compound, C(15)H(17)BrN(2)O(2), both pyrrolidinone rings adopt envelope conformations. The crystal packing is characterized by short C-Br⋯O=C inter-actions [Br⋯O = 3.1730 (13) Å], leading to supra-molecular dimers. Inter-molecular C-H⋯O and C-H⋯π inter-actions are also observed.

In the mol-ecule of the title compound, C(10)H(10)N(2)O(2), the rings are nearly coplanar, making a dihedral angle of 2.35 (5)°. In the crystal structure, inter-molecular C-H⋯O, C-H⋯N and O-H⋯O hydrogen bonds link the mol-ecules, generating R(4) (4)(22) and R(4) (4)(24) ring motifs to form a three-dimensional network. A weak π-π inter-action between the pyridazinone and benzene rings further st...

In this article I argue that the concern with gender relations and the challenges female activists were facing foreclosed any discussion of the transformation activism signalled for male comrades, and thus for wider society. I am particularly interested in men’s own views of their social roles and personal predicaments as the more subtle processes of transformation in the lives of male activist...

Most analyses of the East Asian financial crisis have focused on its causes and the links between currency and banking crises. However a related question is what happens in the aftermath of a crisis? What factors determine the path of an economy in the post-devaluation phase? Does it swiftly bounce back, with the crisis being followed by a period of economic recovery, or does it face a period o...

The ability to manage extreme disasters of any type and their aftermath has been observed to be a challenge for government. This is because extreme disasters are known to disrupt and harm social, economic, business, human welfare and the environment when preparation for them are inadequate or ineffective. Complex, extreme or catastrophic events have inherent characteristics which put a consider...

In this research, we examine the relationship between power and three characteristics of construal—abstraction, valence, and certainty—in individuals’ verbatim reactions to the events of September 11, 2001 and during the immediate aftermath of the terrorist attacks. We conceptualize power as a form of social distance and find that position power (but not expert power) was positively associated ...

In the title compound, C(26)H(43)N(7)O, each piperazine ring adopts a chair conformation. Two 1-methyl-piperazine rings bond to one Csp(3) of the pyrrole ring via the piperazine N atoms, while the third one links to the N atom of the indolin-2-one unit through a flexible ethyl group with an almost syn conformation. In the crystal, mol-ecules are connected through methyl-ene-carbonyl C-H⋯O inter...

Good Morning. It is indeed my privilege to be addressing you today in this Conference in which officials from industry and banking sector are participating. Today, I want to reflect on some of the challenges and dilemmas that we face as regulators of the banking system. A few of these challenges and dilemmas are in the context of the rapidly evolving regulatory landscape in the aftermath of the...
