The Approach of Complex Insert Packaging Fabrication in Stereolithography

The approach of complex insert packaging fabrication in stereolithography is studied in the paper. There are many difficulties being overcome, such as the dispensing shadowing problem caused by the geometric shape of insert, the polymer feeding problem caused by greater insert height than the layer thickness, and the positioning problem of insert that leads to instability of packaging. These drawbacks led to unsatisfactory results of the insert packaging in stereolithography. In order to solve the problems, a new method of complex inserts packaging fabrication in stereolithography is proposed in this paper. Based on the geometric information, function and assembly direction of the inserts, the packaging approach is developed. The approach proposed in this paper has been verified by experiments. It brings considerable contributions to the application of insert packaging in stereolithography. It is also favorable to the improvement of insert packaging efficiency and assembly fabricationMechanical Engineerin

From Value Protection to Value Creation: Rethinking Corporate Governance Standards for Firm Innovation

A company’s pro-innovation needs are often met by the exploitation of its resources, widely defined. The resource-based theory of the firm provides immense empirical insights into how a firm’s corporate governance factors can contribute to promoting innovation. However, these implications may conflict with the prevailing standards of corporate governance imposed on many securities markets for listed companies, which have developed based on theoretical models supporting a shareholder-centered and agency-based theory of the firm. Although prevailing corporate governance standards can to an extent support firm innovation, tensions are created in some circumstances where companies pit their corporate governance compliance against resource-based needs that promote innovation. In the present context of steady internationalization and convergence in corporate governance standards in global securities markets towards a shareholder-centered agency-based model, we argue that there is a need to provide some room for accommodating the resource-based needs for companies in relation to promoting innovation. We explore a number of options and suggest that the most practicable option would be the development of recognized exceptions that deviate from prevailing corporate governance standards. We further suggest as to how an exceptions-based regime can be implemented in the U.K. and U.S., comparing the rules-based regime in the U.S. with the principles-based regime in the U.K
