Complexity Theory for a New Managerial Paradigm: A Research Framework

In this work, we supply a theoretical framework of how organizations can embed complexity management and sustainable development into their policies and actions. The proposed framework may lead to a new management paradigm, attempting to link the main concepts of complexity theory, change management, knowledge management, sustainable development, and cybernetics. We highlight how the processes of organizational change have occurred as a result of the move to adapt to the changes in the various global and international business environments and how this transformation has led to the shift toward the present innovation economy. We also point how organizational change needs to deal with sustainability, so that the change may be consistent with present needs, without compromising the future

Circadian Changes in Susceptibility of Young Honeybee Workers to Intoxication by Pyrethroid, Carbamate, Organophosphorus, Benzoyl Urea and Pyridine Derivative Insecticides

In the years 2009 and 2010, in the apiaries surrounding Tarnobrzeg and Leżajsk, Poland (close to the Carpathian Mountains) research was carried out on diurnal changes in the sensitivity of young honey bee (Apis mellifera) workers to insecticides from various chemical groups: pyrethroids (esfenvalerate, cyhalothrin, alpha-cypermethrin, beta-cyfluthrin, deltamethrin), derivatives of pyridine (pyriproxyfen), carbamate (pirimicarb), organophosphate (diazinon), and benzoyl urea derivative (teflubenzuron). The analyses consisted of intoxicating subsequent groups of honey bees in 2-hour intervals, for a period of 24 hours with selected xenobiotics. The results received indicate that the honey bee shows a statistically significant susceptibility to insecticides, changing in the diurnal rhythm
