For driving the economy, SMEs must be able to survive in an increasingly competitive business competition. This study examines influence of the external environment and competitive strategies on performance of SMEs in Yogyakarta. Competitive strategy used in this study is Porter generic strategies are cost leadership and differentiation, while the external environment used is environment dynamism and environment hostility. Based on 106 respondents who responded to the questionnaire, the results showed that cost leadership affects the performance of SMEs in Yogyakarta, but differentiation strategy doesn't effect on the performance of SMEs in Yogyakarta. Differentiation strategy does'nt effect on performance of SMEs because there is less supported by the SME workforce skilled in applying innovation to improve its performance. The other results in this study are environment dynamism is not a variable that moderates the relationship strategy to performance of SMEs, while environment hostility is variable that moderates the relationship cost leadership to performance of SMEs but is not a variable that moderates the relationship differentiation to performance of SMEs

This research was designed into three steps: (1) Portfolios formation; (2) Test of Existence; and (3) Regression analysis, using the observation period of six years starting from 2002 to 2007. We found that winner-loser anomaly has been more significant in affecting abnormal return for the period of 2002–2007, despite that both accrual and winner-loser anomalies were indicated to exist in the period of observation. The test of accrual anomaly existence during six-year observation period has revealed that in 2003, low accrual firms had generated higher abnormal returns compared to the high accrual firms, for which it indicates the existence of accrual anomaly. The existence of winner-loser anomaly is justified by the significant effect of overreaction on the ...

The test of accrual anomaly existence during six-year observation period has revealed that in 2003, low accrual firms had generated higher abnormal returns compared to the high accrual firms, for which it indicates the existence of accrual anomaly. The existence of winner-loser anomaly is justified by the significant effect of overreaction on the ...

Its production contributed to 35.83% of the total production of tuna in 2013. The study was conducted to assess the population dynamics of this species in FMA 573, based on length-frequency data collected in 2013-2017, and was analysed using FiSAT II software. The results obtained show length-weight relationship of W = 0.000052 FL2.78, negative allometric growth and growth equation of Lt = 194.25 (1-e-0.51 (t + 0.1889)). The length at first capture was estimated at 140 cm FL. Recruitment season occurs between July and September, with a peak in August. The rate of total mortality (Z) was 2.32 yr-1, including natural mortality rate (M) of 0.69 yr-1 and fishing mortality rate (F) of 1.63 yr-1. The exploitation rates of yellowfin tuna were estimated to be 0.70, indicating that it has exceeded the optimum exploitation rate (E = 0.5) and that overexpl...
