    Macroeconomic determinants of stock market fluctuations: The case of BIST-100
    (MDPI Multidisciplinary Digital Publishing Institute, 2019) Demir C.
    The purpose of this study is to analyze the impacts of some prominent macroeconomic factors on the Turkish Stock Market index, BIST-100 (Borsa Istanbul-100). For centuries, and mostly since the 20th century, stock markets are at the heart of economies. In our era, the largest economic crises arise from the stock market instabilities and thus, the stock markets are the focus of interest of the economy. Economists, investors, and policymakers try to predict the tendency of share prices, which substantially depend on foreign and domestic macroeconomic factors. Within this purpose, this study tries to investigate the impact of some selected macroeconomic factors on BIST-100 index over the 2003Q1-2017Q4 period. The findings obtained from the quarterly data via the ARDL Bounds Test suggest that economic growth, the relative value of the domestic currency, portfolio investments and foreign direct investments raise the stock market index while interest rate and crude oil prices negatively affect it. The results briefly reveal that the Istanbul Stock Exchange Market needs stronger domestic currency, higher international capital inflows, and lower energy and investment costs. © 2019 by the author.

    The influence of trait emotional intelligence on archers’ autonomic cardiac recovery responses immediately after a shooting session
    (MDPI Multidisciplinary Digital Publishing Institute, 2019) Dal N.
    The present study aimed to investigate the association between trait emotional intelligence and heart rate variability (HRV) recovery responses of archers immediately after a shooting session. The sample included 87 novice archers ranging in age from 18 to 26. Participants first completed Schutte Emotional Intelligence Inventory. Then, they shot 10 arrows from 18 m to an 80-cm diameter target in four minutes. Afterward, participants’ HRV recovery responses were measured during a four-minute recovery period. In this study, HRV was represented in terms of low frequency (LF), high frequency (HF), and LF/HF ratio. Results indicated a significant relationship between emotional intelligence and HRV recovery responses. A regression model containing emotional intelligence sub-dimensions was able to explain a significant amount of variance in HRV frequency domain parameters. Besides, high emotional intelligence archers were found to have higher-level LF and HF power but a lower LF/HF ratio than their low emotional intelligence counterparts. Taken together, the results observed in the present study indicated that emotional intelligence might give rise to more adaptive HRV recovery responses following a demanding arrow shooting session. © 2019 by the author.
