Knickerbocker's theory does not explain why the first firm in an oligopoly decides to undertake FDI rather than to export or license. (Hills, 2008) also suggested that the imitative theory does not address the issue of whether FDI is more efficient than exporting or licensing for expanding abroad.
Isometrically, the lower back, the upper back, the abdominals, the trunk muscles, the costal muscles, and the shoulders and arms are all essential to the exercise and thus are trained when squatting with the proper form.
Yes, but squatting shoulder width will train more muscle mass, and sumo squatting will train the muscles which 'operate' (to simplify it) at the wide stance, which incidentally is the stance which someone is likely able to squat the most*, due to leverages and range of motion.
