This study was designed to investigate host country national (HCN) categorization of female expatriates, in two samples-U.S. and India. Two hundred and twenty-two HCNs (104 in the U.S. and 118 in India) participated in the study. Consistent with prior research [e.g., Tung, R. L. (1998). American expatriates abroad: From neophytes to cosmopolitans. Journal of World Business, 33: 125-140], we found that female expatriates from the U.S. were not discriminated against. Indeed, we found that female expatriates from the U.S. were preferred by Indian HCNs, as co-workers, significantly more than male expatriates from the U.S. We discuss implications for organizations and offer suggestions for future research. © 2006 Elsevier Inc.

Our study of 116 new product development projects in Taiwanese Information Technology (IT) firms show that horizontal linkages more strongly impact on new product innovativeness than vertical linkages. The firm's learning ability or absorptive capacity increases new product innovativeness. It also moderates the impacts of corporate and research institute linkages on new product innovativeness. Moreover, we confirm that knowledge gains mediate the positive impacts of absorptive capacity and external linkages on new product innovativeness.

To guarantee QoS for multicast transmission, admission control for multicast sessions is expected. Probe-based multicast admission control (PBMAC) scheme is a scalable and simple approach. However, PBMAC suffers from the subsequent request problem which can significantly reduce the maximum number of multicast sessions that a network can admit. In this letter, we describe the subsequent request problem and propose an enhanced PBMAC scheme to solve this problem. The enhanced scheme makes use of complementary probing and remarking which require only minor modification to the original scheme. By using a fluid-based analytical model, we are able to prove that the enhanced scheme can always admit a higher number of multicast sessions. Furthermore, we present validation of the analytical model using packet based simulation. Copyright © 2005 The Institute of Electronics, Information and Communication Engineers.

JPEG2000 is a new coming image standard. In this paper we analyze the performance of error resilience tools in JPEG2000, and present an analytical model to estimate the quality of JPEG2000 encoded image transmitted over wireless channels. The effectiveness of the analytical model is validated by simulation results. Furthermore, analytical model is utilized by the base station to design efficient unequally error protection schemes for JPEG2000 transmission. In the design, a utility function is denned to make a tradeoff between the image quality and the cost for transmitting the image over wireless channel. © 2002 IEEE.
