The current combat motivation model based on primary group thesis assumes that the main force behind motivation is peer-bonding or otherwise known as unit cohesion. Cohesion is perceived as an all-encompassing factor that leads to satisfactory (or unsatisfactory in lack thereof) military effectiveness and performance in conflict environments. However, the article identifies three main problems with this perspective: 1. mono-dimensional view of motivation; 2. motivation based on heteronomy, and 3. self-reporting bias. The current model does not consider motivation as a separate entity from cohesion; it does not place motivation as fundamental human value; lastly, it takes motivation as granted by-product of socialization. The article proposes a new combat motivation model based on The Self-Determination Theory. The theory maintains that human motivation requires satisfaction of three psychological needs of competence, relatedness, and autonomy. The degree of satisfaction of those three needs leads to different types of regulated motivations – a continuum from intrinsic to extrinsic – each of which has specifiable consequences for learning, performance, and well-being of an individual. 相似文献

ABSTRACT Under what conditions are cyber-weapons effective in nuclear counter-proliferation? With continued interest in nuclear proliferation professed by Iran, North Korea, and Saudi Arabia, a discussion of the effectiveness of counter-proliferation measures remains relevant. Cyber-attacks as military option in a state-on-state conflict still requires additional corroborating evidence to make conclusions about its long-term effectiveness. This work analyses the general applicability of cyber-weapons and their usefulness in nuclear counter-proliferation. Through a comparative case study of Operation Orchard, Stuxnet, and recent “Left-of-Launch” operations against North Korea, the essay finds that cyber-operations are not particularly effective against nuclear programmes that are in the later stages of their development. They can disrupt and delay a nuclear programme temporarily, if the attack remains clandestine, but cannot halt nuclear proliferation all together. However, effectiveness increases if they are used in combination with conventional weapons. The article addresses a topic of interest to national-level decision-makers: whether cyber-operations can and should play a role in nuclear counter-proliferation. 相似文献
