  The concept of external governance tries to define the expanding scope of EU rules beyond EU borders. This article presents the theoretical foundations of the concept, differentiating the various institutional modes according to which external governance may take place. Due to the financial and economic crisis the European Union is forced to strengthen its competitiveness opposite to cohesion. In the second part of the study I present the five mechanisms by which the European Union may foster its position in the global competition. The five mechanisms are as follows: extension of the political space of the EU, expansion of the regulation mechanisms of the EU, active coaching of international organisations, territorial extension of the EU’s influence, division of the costs of globalization. After that I deal with the different forms of economic patriotism. Economic patriotism plays crucial role in maintaining the performance and strengthening the position of some preferred domestic industries, ‘national champions’. Tools of economic patriotism differ due to ideological affinities.

  The social functions of tertiary education have gone through considerable changes with the transformation of economic environment in the more than two past decades. In the decade after the political transformation the number of students in the tertiary education increased more than threefold. Personal interests, social needs and the demands of the society lay different claims to the performance of this sector. The needs for structural transformation of the tertiary education system are connected with the development of social and economic processes. The changes of legal regulations determining the operation of the sector are induced by these factors, which refer to the autonomic characters of the public participants. Tertiary education possesses a specific market environment each of whose characters – both the supply and demand sides – strive for the enforcement of self-regulatory mechanisms.

  Leptin, a hormone primarily produced by adipose tissue, regulates the energy balance, metabolism, and reproductive functions. This review explores leptin's role in calf development from embryogenesis to puberty. Leptin expression is strongly influenced by the nutritional status, with circulating levels dependent on adipose tissue mass and modulated by metabolic hormones such as insulin and glucocorticoids. It plays a regulatory role in the embryonic cell division, adipogenesis, and postnatal energy metabolism. Additionally, leptin modulates appetite, the growth hormone secretion, and the reproductive system maturation. Its presence in the colostrum and milk highlights its significance in the early calf development, influencing the neonatal metabolism and immune function. As calves approach puberty, leptin serves as a key metabolic signal for reproductive maturation. A deeper understanding of leptin’s multifunctional role in calf development could contribute to improved livestock growth and reproductive management strategies.
