The Validity of Okun’s Law: An Assessment of United Kingdom’s Unemployment-Output Relationship
Forgone output resulting from unemployment is a real concern for many countries including the United Kingdom which manages to keep it unemployment rate at an average of 7% over the last 43 years. This paper provides an assessment of the unemployment-output relationship by examining the validity of okun’s law, using quarterly time series data from 1971- 2013. The empirical evidences show negative correlation, implying that Okun’s law interpretation is applicable to United Kingdom with economic growth rate of 1.8% required to keep unemployment constant. While the evolution of the unemployment rate is also influenced by other unforeseen variables like productivity, severe winter weather condition and the Diamond Jubilee in 2012.
[Effects of dance exercise on exercise intention and exercise-related affect of postmenopausal women].
PURPOSE
A dance exercise program was performed to investigate the effects of exercise on exercise intention and exercise-related affect as these are important determinants of exercise behavior.


METHOD
The subjects were overweight (23< or =BMI< or =25) or obese (BMI> or =25) postmenopausal women (n=14), who participated in an exercise program from May, 2003 through November, 2003 at one public health center located in Kyong-gi Province. Data was analyzed with an SAS PC program.


RESULT
Exercise intention was significantly increased after the exercise program (t=-2.24, P=0.04). Exercise-related affect was also increased, but there was no statistically significant change (t=1.81, P=0.09).


CONCLUSION
This study suggests that exercise participation can increase the level of future exercise behavior by increasing exercise intention and exercise-related affect.
