The purpose of this study was to translate Arnold and her colleagues' (Arnold, Fletcher, & Daniels, 2013) Organizational Stressor Indicator for Sport Performers (OSI-SP) into Chinese and examine its psychometric properties with Taiwanese athletes. In study 1, the psychometric properties of the items and the underlying structure of the translated Chinese OSI-SP were examined. In study 2, we used confirmatory factor analysis to examine the factorial structure and examined measurement invariance across genders. In study 3, we examined concurrent and discriminant validity via correlations among the Chinese OSI-SP, coping self-efficacy, perceived stress, and burnout to provide further evidence of criterion validity. Study 4 examined the test-retest reliability of the Chinese OSI-SP. Across these phases, results showed the 5-factor, 16-item Chinese OSI-SP had adequate factor structure, measurement invariance, criterion validity, and reliabilities. We suggest future studies may use this revised Chinese OSI-SP in Taiwan and other Chinese athletic settings.

Carbon (C), nitrogen (N) and phosphorus (P) contents and ecological stoichiometry and their correlations of litter and soil along 1500 - 1900 m on Wugong Mountain meadow were studied. The results showed that litter C, N and P contents varied in the range of 397.5-458.24, 11.59-17.12, 1.05-2.19 mg ⋅g-1, respectively. Litter C content decreased, and the contents of N and P decreased first and then increased with the increases of altitude. Soil C, N and P contents varied in the range of 51.64-80.01, 3.30-4.77, 0.44-1.09 mg ⋅g-1, respectively. Soil C, N and P contents first increased and then decreased with the increases of altitude. However, soil P varied much less along the altitude gradient. Litter C:N, C:P and N:P varied in the range of 24.7340.36, 203.65-463.08, 7.16-13.80, respectively, and first increased but then decreased with altitude. Soil C:N, C:P and N:P were 14.95-16.95, 56.87-162.52, 3.69-10.58, respectively. Soil C:N changed little with altitude. Soil C:P and N:P first increased and then decreased with increasing altitude, with the maximum presented at 1600-1700 m. Changes in soil C, N and P contents differed between litter and soil on Wugong Mountain meadow. The mean C, N and P contents as well as C:N, C:P and N:P in litter were higher than those in soil.
