Global-Integration and Local-Responsiveness (IR) framework with four pairs of external environment and appropriate international strategy types has contributed significantly to international business management. Nevertheless, the framework is still incomplete and lacks dynamic features. To deal with such limitations and enhance the theory, this paper, therefore, brings dynamic features regarding both environment and strategy into the IR grid. Under a dynamic capability angle with three steps of sensing, seizing and transforming [30], the dynamic global integration and local responsiveness framework – a new concept building for international business – would be explicated.

Prevention of disability is one of the most significant tasks of child and adolescent psychiatry. Obtaining data on the dynamics of the number of people with disabilities and the factors affecting this indicator seems to be one of the relevant aspects. Aim: to trace the dynamics of the number of children with disabili-ties and to assess the change in the structure of early disability over the past decades. Materials and Meth-ods. A comparative analysis of two cohorts of patients was carried out: 1st - patients born in 1990-1992. (1203 patients (men - 914, 76%; women - 289, 24%)) who applied to the district neuropsychiatric dispensa-ry for outpatient care in childhood and adolescence; II - children and adolescents born in 2005 - 2018 (602 patients (male - 410, 68%; female - 192, 32%), ob-served at the time of the study by a child psychiatrist in the neuropsychiatric dispensary. Research methods: clinical and psychopathological; follow-up; statisti-cal. Results. Comparison of the number and nosologi-cal distribution of disabled children in two cohorts showed that over the 15th year there has been a shift towards an increase in the proportion of disabled children among patients observed by child and ado-lescent psychiatrists. The increase in the number of children with disabilities was due to those suffering from childhood autism and other disorders of general development. There were no statistically significant differences in the number of people with disabilities who received benefits before the age of 7, as well as differences in gender ratios among disabled people in the two cohorts. Conclusion. Early disability is a mul-tifactorial phenomenon, prevalence, dynamics, the structure of which depends not only on clinical, but also on socio-administrative realities. Children with autism require increased attention, since there has been a multiple increase in the number of patients with this diagnosis.

Formulation Factors

In this paper, it was analysed the influence of formulation factors over obtaining oxicam hydrogels, using the statistical analysis. Data analysis and predictive modeling by multivariate regression offers a large number of possible explanatory/predictive variables. Therefore, variable selection and dimension reduction is a major task for multivariate statistical analysis, especially for multivariate regressions. The statistical analysis and computational data processing of responses obtained from different pharmaceutical formulations, via different experimental protocols, lead to the optimization of the formulation process. It was found that the most suitable pharmaceutical formulations based on oxicams with the possibility of rapid release contained cyclodextrin, in particular 2-hydroxypropyl-b-cyclodextrin.
