Zora Neale Hurston is an African-American novelist, anthropologist. Her famous novel Their Eyes Were Watching God to some extent reflects the pursuit of self-actualization of the female protagonist Janie. The psychological term Maslow's Hierarchy of Needs is implemented in this study to help to analyze the process of Janie's self-actualization, which illustrates how Janie realized self-fulfillment and appreciated the intrinsic worth of her surroundings and to experience the world deeply through marriages to three different men. 展开更多

BACKGROUND It is very important to provide effective nursing programs to regulate the physical and mental state of patients and to improve treatment compliance after interventional surgery for coronary heart disease(CHD).AIM To explore the effect of a nursing intervention based on Maslow’s hierarchy of needs theory on patients with CHD undergoing percutaneous coronary intervention.METHODS Ninety-four patients with CHD undergoing interventional surgery in our hospital from January 2020 to February 2021 were randomly divided into a research group(n=47)and a control group(n=47).The control group received routine nursing,and the research group received a nursing intervention based on Maslow’s hierarchy of needs theory.The scores of self-efficacy,negative emotion[depression(SDS),anxiety(SAS)],intervention compliance(standardized medication,moderate exercise,healthy diet,and regular review),and nursing satisfaction were calculated before and after intervention for the two groups.RESULTS Before intervention,there was no significant difference in the scores of disease general management self-efficacy,disease management self-efficacy,and total self-efficacy between the two groups(P=0.795,0.479,and 0.659,respectively).After intervention,these three scores in the research group were higher than those in the control group(P<0.001).Before intervention,there was no significant difference in the scores of SAS and SDS between the two groups(P=0.149 and 0.347,respectively).After intervention,the scores of SAS and SDS in the research group were lower than those in the control group(P<0.001).The standardized drug use rate(97.87%),moderate exercise rate(97.87%),healthy diet rate(95.74%),and regular reexamination rate(97.87%)in the research group were higher than those in the control group(85.11%,82.98%,80.85%,and 87.23%,respectively)(P=0.027,0.014,0.025,and 0.049,respectively).Nursing job satisfaction in the research group(93.62%)was higher than that in the control group(78.72%)(P=0.036).CONCLUSION A nursing program based on Maslow’s hierarchy of needs theory can effectively alleviate negative emotion,enhance self-efficacy and intervention compliance,and ensure that the patients are highly satisfied with the nursing work. 展开更多

In this paper,on the basis of analyzing farmers' dominant position in society and explanation of farmers' rationality,we make use of Maslow's hierarchy theory of needs to divide farmers' needs into three levels in accordance with the different stages: survival needs,interpersonal harmony and social responsibility,which are the needs hierarchies for farmers to satisfy themselves. We combine Maslow's hierarchy theory of needs and farmers' rationality and confirm that farmers do have rationality and it is in a dynamic condition. 展开更多

Maslow' s Hierarchy of Needs, which is one of the important motivation theories, has become a strategy used by managers to motivate employees. The project will explain the definition of motivation and Maslow' s Hierarchy of Needs from the perspective of organizational behavior and the strengths and weaknesses of the theory. Then it will consider how the theory is applied effectively in the USA and Northwest Europe and ineffectively in some developing and undeveloped countries with different economical backgrounds, political systems and cultural preferences. The conclusion suggests that managers should choose motivation systems that fit in the local cultural backgrounds. 展开更多
