English to Romanian Bus/Financial Management entrepreneurship, business, economy

The present authors would argue that the following ‘‘functional spheres’’ comprise the activity of the quintessential entrepreneurial agent.

‘‘Booster’’ sphere: This sphere of activity encompasses the psychosocial elements of the ‘‘human’’ (or ‘‘personal’’) entrepreneur referred to above. That is, apart from the investment of capital (financial sphere) and corporate direction and management (managerial sphere), it is apparent that the ‘‘human’’ (or ‘‘personal’’) entrepreneur takes on other functions of a less tangible nature. These tend to be ‘‘basic initiatives’’ of a psychosocial nature in the business – such as the initiation of an innovative project; the recognition of new profit-making opportunities in the market; and awareness of possible fluctuations in demand in society.

I need the meaning of the "booster sphere" in one or 2 words.
