Sand pebble soil has a wide distribution, and its dynamic characteristics under dynamic loads become an important issue in engineering field. This paper takes a review at research progresses made on saturated sand soil under dynamic loads from 1970’s, and focuses on the progresses made on theoretical research, verification experiments in dynamic deformation and dynamic strength of saturated sand pebble soil under dynamic loads, and future research directions are proposed.

Corporate governance in today's modern economies is growing in importance within the growth accounting equation. Although we look at corporate governance as final product of 20/21st century economies, old economic growth theories were aware of its importance for growth and development. Roots of corporate governance go back to the ancient economies of India and Greece also. This paper offers a consistent literature review assessing the nexus between corporate performance and economic growth. Individual and cross-country studies show corporate governance in majority of the cases positively affects firms performance and in turn nations' economic growth. Empirical and theoretical research show corporate governance is an important growth determinant to be reviewed in the field of growth models. This article summarizes main findings providing future research directions on the corporate governance – economic growth nexus.

Waste printed circuit boards (WPCBs) treatment has been a hot and difficulty topic in handling of electronic waste. Previous research efforts have been put in the methods of separation of metal and nonmetal fractions and how to recycle the metal fractions. The recycling of nonmetal fraction becomes more and more important due to its large volume and hazardous characterizations. In this paper the recycling of nonmetal fractions are summarized and future research directions are discussed, providing reference for the WPCBs recycling industry development.

Insight Into

Conventional machining techniques of ceramics such as milling, drilling, and turning experience high cutting forces as well as extensive tool wear. Nevertheless, non-contact processes such as laser machining and electro-discharge machining (EDM) remain suitable options for machining ceramics materials, which are considered as extremely brittle and hard-to-machine. Considering the importance of ceramic machining, this paper attempts to provide an insight into the state of the art of the EDM process, types of ceramics materials and their applications, as well as the machining techniques involved. This study also presents a concise literature review of experimental and theoretical research studies conducted on the EDM of ceramics. Finally, a section summarizing the major challenges, proposed solutions, and suggestions for future research directions has been included at the end of the paper.

The purpose of this paper is to bring conceptual clarity to the heavy work investment (HWI) construct while building a model based on a review of extant empirical and theoretical research and to encourage further discussion and investigations regarding the nature of HWI, specifically its individual level antecedents, dimensions, and outcomes for both the employee and the organization. The proposed theoretical framework builds upon the Job Demands–Resources model and conceptualizes HWI on a continuum of workaholism and work engagement. Specific propositions for the antecedents and outcomes of the HWI continuum are developed. The paper ends with a discussion of future research directions.
