Influence of Control Mechanism on the Flow field of Duct at Mach 1.2 for Area Ratio 2.56

In this paper, the outcome of the experimental investigation and the flow field development in the duct at supersonic Mach number of 1.2 is presented. The experiments were conducted at various NPR which covers the condition of correct expansion and under expansion. A Convergent-divergent (C-D) nozzle which is connected with the suddenly expanded duct of the diameter of 16 mm of area ratio 2.56. The recirculation zone is controlled by using the microjets of 1 mm of orifice diameter which are placed at 90 degrees interval at 6.5 mm from the central axis of the main jet. The L/D of the duct was used in the investigation was from 1 to 10, and the NPR at which the experiments were conducted considered are in the range from 3, 5, 7, 9 and 11.

Towards a framework for controls as determinants of export performance

PurposeThe purpose of this paper is to review and synthesize empirical literature concerning the role of control mechanisms in export relationships, and to develop a model for controls as determinants of export performance.Design/methodology/approachTo identify relevant papers, a variety of keywords is used in a computerized, bibliographic search, accompanied by manual checking of references in previous research. A combination of content analysis and integrative assessment is adopted to synthesize the findings and develop the framework.FindingsTo a great extent, the results provide support to the argument that the influence of control mechanisms on export performance is contingent upon firm strategy and characteristics, the governance structure and relationship atmosphere established in the exchange relationships, and foreign market characteristics.Research limitations/implicationsThe analysis points to a lack of consensus concerning how to define controls. Subsequently, the review and analysis rest on the definition of control mechanisms and export performance. The descriptions, synthesis, and proposed framework indicate a connection between implemented controls, internal, external, and relational dimensions, and consequently to the need of adjusting the control mechanisms to the environment. Hence, the analysis, synthesis, and proposed framework, give advice to managers involved in exporting, as well as providing guidance for future research.Originality/valueThis study is the first to analyze and integrate empirical literature concerning controls as determinants of export performance. As such, the study may inspire further research.

The Influence of Control Mechanisms and Uncertainty on Partner Selection and Cooperation

This study investigates whether the use of two different control structures (authority and contingent rewards) and different types of uncertainty (firm specific versus market uncertainty) have an impact on partner selection decisions. The results of an experimental study indicate that buyers diversify the risk of firm-specific uncertainty by spreading the transaction more equally over different suppliers only when controlling their supplier by authority but not by rewards. The results also show that with rewards, buyers are more inclined to rely on reciprocal suppliers which leads to more repeated interactions with one favored supplier. This paper informs future studies that control structures determine the success of different selection strategies. This finding can improve current theories on the governance of interfirm transactions.

Alliance motivations, control mechanisms and alliance performance: Evidence from China

Strategic alliance can aid firms to build and sustain their competitive advantages. Firms set up strategic alliance mainly for two purposes: resource acquisition and capability learning. Formal control and social control are two widely adopted control mechanisms to secure the effectiveness of strategic alliance. In this study, we construct a model to analyze the choice of control mechanisms based on alliance motivations and the influence of control mechanisms on alliance performance. Based on a survey of 607 Chinese firms, we find that when resource acquisition is the key motivation behind alliance, formal control should be enhanced. Whereas when capability learning is the main purpose of alliance, social control becomes a better choice. Furthermore, this research also finds that the impact of both formal control and social control on alliance performance are nonlinear. Suggestions are provided on how to effectively use control mechanisms to attain the purposes of strategic alliance and on how to use control mechanisms to enhance alliance performance.
