Communications satellite service providers, acutely aware of their need to remain competitive with terrestrial alternatives, have embraced payload technologies promising to lower their costs of service. Multi-Beam Antennas (MBAs), Digital Channelizers (DCs), Digital Channelizer Beamformers (DCBs) and even Fully Regenerative Processors (FRPs which demodulate, decode, packet switch, encode and mo...

A simple and rapid spectrophotometric method for the determination of sodium dodecyl sulphate (SDS), an anionic surfactant (AS) is developed. SDS forms a yellow coloured complex with acridine orange (ACO), a cationic dye. The complex is extracted in toluene. The absorbance of the complex in toluene layer is measured at maximum wavelength (λmax) of 467 nm. The calibration curve is linear in the ...

Credit ratings affect firms’ access to capital and investment choices. We show that the identity of the credit analysts covering a firm significantly affects the firm’s rating, comparing ratings for the same firm at the same time across agencies. Analyst effects account for 30% of the within variation in ratings. Moreover, the rating biases of analysts carry through to credit spreads on the rat...

Using a survey study of 261 decisions under uncertainty, we explore the factors that explain risk taking behavior and those that predict the importance of a decision. We also examine the relationship between framing and status quo, the similarity between monetary and non-monetary decisions, as well as the similarities and differences among our three subject groups (Undergraduates, MBAs and Exec...

Widely publicized reports of fresh MBAs getting multiple job offers with six-figure annual salaries leave a long-lasting general impression about the high quality of selected business schools. While such spectacular achievement in job placement rightly deserves recognition, one should not lose sight of the resources expended in order to accomplish this result. In this study, we employ a measure...

In order to achieve the multi-user broadcast authentication in WSNs (Wireless Sensor Networks) defending against DoS (Denial-of-Service) attack, a multi-user broadcast authentication protocol in WSNs was proposed based on the improved ECDSA (Elliptic Curve Digital Signature Algorithm) with partial message recovery. The authenticity of the user public key is verified by using bloom filter, which...

CHARISMA ATTRIBUTION DURING ORGANIZATIONAL CHANGE: THE IMPORTANCE OF FOLLOWERS’ CONCERN FOR WELL-BEING Abstract Taking a follower-centric perspective, we examined how charisma attribution to a change leader was influenced by the well-being concerns and emotions of organizational members. We conducted three studies to examine how college business students and executive MBA students responded to ...

The presence of a gender gap in entrepreneurship has been well studied in previous literature. There are various contributing factors, including differences in human capital, which has been reviewed less so than social capital. Through a career survey of Wharton MBAs, this research paper 1) examines the presence of an entrepreneurship gender gap; 2) identifies human capital variables that predi...

Using an incentivized measure of individuals’ taste for competition, this paper investigates whether this taste explains subsequent gender differences in earnings and industry choice in a sample of highability MBA graduates. We find that “competitive” individuals earn 9% more than their less competitive counterparts do. Moreover, gender differences in taste for competition explain around 10% of...

Memristor-based accelerator (MBA) has demonstrated its capability in accelerating matrix-vector multiplication (MVM) with high performance and energy efficiency. However, it is hard to determine whether how well an application can benefit from MBAs a heterogeneous computing architecture. In this article, we propose simulation framework called MHSim evaluate the efficiency of applications runnin...
