Abstract

Twenty-two coal samples and eleven parting samples were taken from Gashun Coal Mine, Hoxtolgay coalfield, Xingjiang Autonomous Region, and the samples were analyzed by using optical microscopy. The results indicate that the dominant macerals are vitrinite (av. 76.6%) with minor amounts of inertinite (av. 18.84%) and low liptinite (av. 2.7%), along with low content of mineral matters (av. 1.86%). All GI, TPI, VI, GWI values and two facies diagrams indicate that the main coal facies are in limnic area. Meanwhile, the overall petrographic composition and coal facies types indicate that the coal formed in strong wet reducing peat accumulating conditions which were the lacustrine marshes.

Abstract

Cobalt is an extremely useful element, but there are very few separate cobalt deposits in China and imported cobalt ores are usually toxic. In order to develop more low-toxicity cobalt resources, China has to encourage exploration and development of this element. Samples are taken from Hanxing iron ore tailings and analyzed by ICP-MS and barium chloride titration experiments. The results indicate that the cobalt content is relatively high in Hanxing iron ore tailings, and some exceed the industrial grade. Therefore, with the depletion of cobalt resources, iron ore tailings are bound to become an important resource in China, and as these tailings are abundant in the Hanxing area, this area is expected to be of high development value.

Abstract

Purpose

This paper investigates the relationship between human capital, economic freedom, governance performance, and economic growth and whether institutional factors such as governance performance and economic freedom mediate the association between human capital and economic growth.

Design/methodology/approach

In this study, the authors apply the panel data regression method to verify five hypotheses and check the robustness of the empirical findings from four aspects (chow test, panel unit root test, granger test and generalized method of moments) based on the data covering China, India, Russia, Brazil and South Africa from 2000 to 2018.

Findings

After multiple tests with mixed methods, the empirical results show that the relationship between human capital and economic growth is not linear but inverted U-shaped. Furthermore, human capital has a positive effect on economic growth only in a certain period of time, and governance performance positively moderates the effect of human capital on economic growth in BRICS.

Originality/value

First, the impact of human capital on economic growth is not linear but an inverted U-shaped and governance performance moderates the effect of human capital on economic growth in BRICS. The study and research model enhances the authors’ insights on the advantage and challenges of human capital in the future. Second, the proposed multi-methods in the study accurately forecast economic growth which partially solves endogenous problems because of reverse causality.

Abstract

Purpose

This study aims to examine the effect of financial inclusion (FI) and financial openness (FO) on the development of capital markets in Africa.

Design/methodology/approach

The study uses data from 34 countries over 18 years (2004–2021) and adopts the panel autoregressive distributed lag and pooled mean group approach, with economic growth, trade openness, government expenditure and institutional quality as control variables.

Findings

The analysis reveals that both FI and FO contribute to the long-term development of capital markets across all income levels within the sampled countries. The interaction between FI and FO enhances capital market development (CMD) over the long run. This finding indicates that FO particularly enhances the development of capital markets in economies with comparatively lower levels of FI.

Practical implications

The findings of this research underscore the importance for policymakers and professionals to adopt guidelines and regulations that promote FI and openness. Such measures can bolster the development of strong financial systems by improving access to the formal financial sector, and by contributing to the growth of capital markets.

Originality/value

The study is robust to the use of a multidimensional financial and CMD index. It is one of the pioneering studies that explore the relationship between FI and FO, and how this interaction influences CMD.

Abstract

Purpose

Under the de-capacity circumstances of coal production in China, the purpose of this paper is to examine the processes underlying the association between job insecurity (JI) and miners’ safety performance, proposing that resource consumption is a prominent theoretical explanation for this association. By developing a mediation model, the authors examined the mediating role of emotional exhaustion (EE) between JI and miners’ safety performance.

Design/methodology/approach

Through the time-lagged survey method, the authors collected 349 samples from three coal mines in Shanxi Lu’an Group, the hypotheses were tested through confirmatory factor analysis, structural equation model analysis and bootstrapping in AMOS software.

Findings

Results shed light on that JI negatively predicts the safety performance subfactors, including safety compliance (SC) and safety participation (SP). EE plays a partial mediating role between JI and safety performance. In particular, the finding indicated that JI exerts a more significant impact on SP than SC, revealing that JI produces a more significant adverse effect on miners’ conscious safety behaviors than skill-based safety behaviors.

Originality/value

This study contributes to display the influence path of JI as a stressor on miners’ safety performance in the coal mine rather than a stimulus. The mediation model results not only help us understand the association between JI and safety performance but also provide a feasible way to mitigate the negative effects of JI.
