Voluntary Termination

Does grief occur subsequent to elective abortion? This basic question is addressed using maternal-infant bonding as a basic theoretical framework. The temporal sequence of the three medical procedures: vacuum aspiration; dilitation and evacuation; and intrauterine induction, facilitated the testing of basic hypotheses deduced from bonding theory, as well as exploration of the grief reaction to the voluntary termination of a pregnancy. Grief associated with elective abortion was found to be symptomatically similar to grief experienced following involuntary fetal/infant loss, and may be initiated by the decision to terminate the pregnancy.

The early descriptions of chemical bonding in minerals and geological materials utilized purely ionic models. Crystals were regarded as being made up of charged atoms or ions that could be represented by spheres of a particular radius. Based on interatomic distances obtained from the early work on crystal structures, ionic radii were calculated for the alkali halides (Wasastjerna, 1923) and then for many elements of geochemical interest by Goldschmidt (1926). Modifications to these radius values by Pauling (1927), and others took account of such factors as different coordination numbers and their effects on radii. The widespread adoption of ionic models by geochemists resulted both from the simplicity and ease of application of these models and from the success of rules based upon them. Pauling’s rules (1929) enabled the complex crystal structures of mineral groups such as the silicates to be understood and to a limited extent be predicted; Goldschmidt’s rules (1937) to some degree enabled the distribution of elements between mineral phases or mineral and melt to be understood and predicted. Such rules are further discussed in later chapters. Ionic approaches have also been used more recently in attempts to simulate the structures of complex solids, a topic discussed in detail in Chapter 3. Chemical bonding theory has, of course, been an important component of geochemistry and mineralogy since their inception. Any field with a base of experimental data as broad as that of mineralogy is critically dependent upon theory to give order to the data and to suggest priorities for the accumulation of new data. Just as the bond with predominantly ionic character was the first to be quantitatively understood within solidstate science, the ionic bonding model was the first used to interpret mineral properties. Indeed, modern studies described herein indicate that structural and energetic properties of some minerals may be adequately understood using this model. However, there are numerous indications that an ionic model is inadequate to explain many mineral properties. It also appears that some properties that may be rationalized within an ionic model may also be rationalized assuming other limiting bond types.

Governance Disclosure

Purpose – The purpose of this paper is to investigate Indian companies’ compliance with the mandatory and voluntary corporate governance disclosure requirements of the Stock Exchange Board of India’s Clause 49. Design/methodology/approach – The authors develop a corporate governance disclosure index and sub-indices based on Clause 49. Annual reports of listed Indian companies are scored according to their disclosures in two periods – pre and post amendments to Clause 49. Findings – Indian companies are highly compliant with corporate governance disclosure requirements of Clause 49. Disclosure increases significantly after amendments to Clause 49 as the penalties for non-compliance increase in severity. Government controlled firms disclose significantly less than privately owned firms. Research limitations/implications – The findings are consistent with bonding theory and the authors note that the presence of an independent regulator (with powers to take action against violators) provides corporate India with additional incentives to comply with corporate governance reform. Practical implications – These findings have important implications for policy makers and regulators as they contribute to the debate on the choice between formal corporate governance regulation versus informal self-regulation. The study also has implications for understanding factors associated with the adoption of disclosure practices in general. Originality/value – This is the first study to examine disclosure compliance in a major developing country pre and post amendments to mandatory corporate governance requirements. Prior evidence indicates a low level of disclosure in India but our results demonstrate an improvement in line with our theoretical predictions that suggests, India is converging towards an Anglo-Saxon model of corporate governance.
