The existing corporate environmental disclosure (CED) research focuses primarily on large companies operating in a single jurisdiction, leaving a gap of knowledge regarding the subsidiary operations of multinational corporations. In this study, consolidated narrative interrogation (CONI) is used to quantify CEDs presented in annual and stand-alone sustainability reports published over a 15-year span between 2002 and 2016 by agrochemical companies operating in India. Results show that the diversity, the quantity, and the quality of CED vary significantly, but generally each of them has been improving over time—most notably following the revisions to the Companies Act in 2013. The study finds that the subsidiaries of multinational agrochemical corporations implemented CED practices more strongly associated with those of domestic companies than those found in the reports produced by their parent companies. The CED of both subsidiary and domestic companies appears to reflect concerns of local legitimacy.
This thesis research seeks to provide insight into the corporate environmental disclosure practices of multinational agrochemical parent corporations, their public subsidiaries in India and domestic Indian agrochemical corporations. The study analyzes whether environmental disclosure practices are more strongly influenced by country-of-operation or country-of-origin. These analyses use a recently developed content analysis instrument named consolidated narrative interrogation (CONI), which is capable of measuring the diversity, quantity and quality of environmental disclosures.
Results indicate that the quantity, quality and diversity of Indian agrochemical subsidiaries’ corporate environmental disclosures are more similar to domestic Indian companies than their parent companies. These results may be explained by the institutional theory. The results of this study are of significance because they provide evidence that multinational corporations may not transfer their environmental disclosure practices to host countries. Instead, environmental disclosure practices of subsidiaries are localized to their host country and are not standardized with parent company practices.
Fractional calculus has recently been applied to the mathematical modelling of tumour growth, but its use introduces complexities that may not be warranted. Mathematical modelling with differential equations is a standard approach to study and predict treatment outcomes for population-level and patient-specific responses. Here, we use patient data of radiation-treated tumours to discuss the benefits and limitations of introducing fractional derivatives into three standard models of tumour growth. The fractional derivative introduces a history-dependence into the growth function, which requires a continuous death-rate term for radiation treatment. This newly proposed radiation-induced death-rate term improves computational efficiency in both ordinary and fractional derivative models. This computational speed-up will benefit common simulation tasks such as model parameterization and the construction and running of virtual clinical trials.
