W present some empirical regularities in the market shares of brands. Our cross-sectional data on market shares consists of 1,171 brands in 91 product categories of foods and sporting goods sold in the United States. One of our results is that the pattern of market shares for each of the categories (many of which are fundamentally dissimilar, such as breakfast cereals and rifles) is represented...

With the advent of time-based competition, the speed with which new products can be developed and introduced into a market is an important managerial aspect of time-based strategy. The relationship between the allocation of decision-making power within organization and new product development (NPD) speed is investigated empirically using Chinese data. The results of correlation analysis show th...

In this paper, we present a variant of Datalog language (we call it Datalog ) able to deal with weights on ground facts and to consequently compute a feedback result for the goal satisfaction. The weights are chosen from a proper c-semiring. In our context, our goal is to use this language as a semantic foundation for languages for expressing trust relationships. As a matter of fact, many of th...

Sharing sensitive information across security domains is an important requirement for knowledge intensive collaborative work, but such sharing may impose risks on security and privacy integrity. Research has increasingly recognized the role of trust in minimizing the risk of information sharing across untrusted or unknown entities. To this extent, trust negotiations[1][3][15][20] have emerged a...

Grounded Theory provides a useful approach for eliciting and justifying subjective characteristics of individuals. A Grounded Theory analysis is carried on individuals who share pictures, with a view to developing a trust management policy model of indiscretion regarding the sharing of photographs.

This work investigates how bargaining power affects negotiations between manufacturers and reverse logistics providers in reverse supply chains under government intervention using a novel three-stage reverse supply chain model for two scenarios, a reverse logistics provider alliance and no reverse logistics provider alliance. Utilizing the asymmetric Nash bargaining game, this work seeks equili...

Risk management is a critical issue in complex product development, especially when suppliers are integrated. The power asymmetry between the supplier and manufacturer may largely influence the development process and affect the occurrence and interaction of risks, and it should be systematically examined. In this paper, we establish a structural model to study the impact of power asymmetry on ...

This study considers empowerment in nurse–manager relations by examining how conflict is handled on both sides and how the critical social perspective has influenced these relations. The authors use inductive analysis of empirical data to explain how (1) nursing work is organized, structured, and circumscribed by centrally determined policies and practices that downplay nurses’ professional jud...
