Secondary Motives: Power Motivation and Achievement Motivation

153
Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...

Power

The concept of work involves force and displacement; meanwhile, the work-energy theorem relates the net work done on a body to the difference in its kinetic energy, calculated between two points on its trajectory. While none of these quantities or relations involves time explicitly, we know that the time available to accomplish work is often just as important as the amount of work itself. For example, sprinters in a race may have achieved the same velocity at the finish, therefore,...

Power and Energy

The power and energy delivered to an element are subjects of great significance in the field of electrical engineering. It is a well-known fact that a 100-watt light bulb emits more light than a 60-watt one. Therefore, power and energy calculations play a crucial role in the analysis of electrical circuits.
Power, defined as the time rate of expending or absorbing energy, is quantified in units called watts (W). The relation between power and energy is mathematically given as

Maximum Power Transfer

Numerous practical applications within engineering disciplines, such as telecommunications, necessitate optimizing power delivery to a connected load. This pursuit, however, entails inherent internal losses, which can either equal or exceed the power supplied to the load. The Thevenin equivalent circuit is helpful in finding the maximum power a linear circuit can deliver to a load. It is assumed in this context that the load resistance can be adjusted.
By substituting the entire circuit with...

Electrical Power

Electric power is the product of current and voltage, represented in units of joules per second, or watts. For example, cars often have one or more auxiliary power outlets with which you can charge a cell phone or other electronic devices. These outlets may be rated at 20 amps and 12 volts, so that the circuit can deliver a maximum power of 240 watts. Consider a 25 Watt bulb and a 60 Watt bulb. The conversion of electrical energy produces heat and light, while the kinetic energy lost by the...

Area of Science:

  • Economic Sociology
  • Entrepreneurship Studies

Background:

  • Entrepreneurship research traditionally uses networks, cognition, and institutions.
  • The role of power in entrepreneurship has been largely implicit.

Purpose of the Study:

  • To pioneer the integration of the concept of power into entrepreneurship research.
  • To illustrate how power dynamics influence entrepreneurial opportunities and their pursuit.

Main Methods:

  • Conceptual paper analyzing the role of power.
  • Examination of coercive, persuasive, and authoritative power forms.
  • Linking context and opportunity development through a power lens.

Main Results:

  • State actors, legacy firms, and entrepreneurs exert power over opportunities.
  • Actors also exercise power to pursue opportunities autonomously.
  • Power's interaction-focused and episodic nature is highlighted.

Conclusions:

  • Explicitly linking context and opportunity development via power enriches entrepreneurship research.
  • Power's ability to transcend boundaries offers new avenues for study.
