The q− difference analog of the classical ladder operators is derived for those orthogonal polynomials arising from a class of indeterminate moments problem.

In this paper we estimate the rate of return to firm investments in human capital in the form of formal job training. We use a panel of large firms with detailed information on the duration of training, the direct costs of training, and several firm characteristics. Our estimates of the return to training are substantial (8.6%) for those providing training. Results suggest that formal job train...

This paper argues that the sharing economy—through the use of the Internet and real time reputational feedback mechanisms—is providing a solution to the lemons problem that many regulators have spent decades attempting to overcome. Section I provides an overview of the sharing economy and traces its rapid growth. Section II revisits the lemons theory as well as the various regulatory solutions ...

This paper studies markets plagued with asymmetric information on the quality of the goods traded. In Akerlof’s setting, sellers are better informed than buyers. In contrast, we examine cases where buyers are better informed than sellers. This creates an inverse adverse-selection problem: The market tends to disappear from the bottom rather than from the top. In contrast to the traditional mode...

This paper presents a preliminary study of an approach that models programmable logic controllers (PLCs) for their effective deployment in industrial control processes. A working model is developed for automatic allocation of PLCs and also a formal verification of Ladder Diagram representations of control processes using the Symbolic Model Verifier (SMV) tool. Automatic resource allocation is a...

In this study, whole lemons were dried using a laboratory convective hot air dryer and the effects of drying temperature on dehydration behaviour and mass transfer characteristics of the lemons were investigated. The drying experiments were conducted using air temperatures of 50, 60 and 75 °C and air velocity of 1 m/s. It was observed that the drying temperature affected the drying time and...

With more organizations looking for employees who take the initiative and respond creatively to the challenges of the job, empowerment becomes important at both individual and organizational levels. Empowered employees are generally more satisfied with their work, committed and effective at work. According to Kanter's structural empowerment, this study examines the role of access to opportunity...
