Our work addresses internal information breaches that emanate from organizational workflows. Information breaches are particularly piquant in organizational workflows, as the underlying tasks constitute natural points where private information on [...]

The massive amount of sensitive survey data about individuals that agencies collect and share through the Internet is causing a great deal of privacy concerns. These concerns may discourage individuals [...]

Technological advances in the collection, storage, and analysis of data have increased the ease with which businesses can make profitable use of information about individuals. Some of this information is private, and individuals are simultaneously becoming more aware of the value of the information and how the loss of control over this information impacts their personal privacy. As a partial solution to these concerns, this paper presents a mechanism that serves two purposes. The first enables the use of private, numerical data in the answering of queries while simultaneously providing a security feature that protects the data owners from a loss of privacy that could result from an unauthorized access. The second develops a compensation model for the use of the data that allows individuals to dynamically redefine their security requirements. The compensation model is built on the information-security mechanism to create the foundation of a market for private information. This paper illustrates how compensation models like the one presented here could be used in a self-regulating market for private information. Additionally, the compensation component of an intermediated market for private information is developed and extensively analyzed. Finally, this paper provides insights and draws several important conclusions on markets for private information.

Utilization of online auction markets to reach consumers and sell new products is a common scenario, established by business sellers. An option approach was developed for sellers, to assess the price and volume of a product. In online auctions, options that provide valid benefits leads to efficiency of markets.

We report the synthesis and characterisation of thiosemicarbazones of Zinc and Cadmium, general formula MCl2.LH (1–8) {Where M = Zn or Cd; L = C11H17N3S, C11H21N3S}. They have been characterised by elemental analyses, FT-NMR (1H, 13C), FT-IR and ESI-Mass spectral studies. Sol-gel transformations of two of the representative compounds (2 and 6) yielded ZnO (A) and CdO (B), respectively. Surprisingly, solvothermal transformation of both of these compounds yielded ZnS (C) and CdS (D) without using any suphonating agent. The XRD pattern of synthesised materials suggested crystalline or amorphous nature of the samples with the particle size ZnO (10 nm), CdO (14 nm), ZnS (12 nm) and CdS (28 nm). Surface morphologies were investigated by SEM images. Absorption spectra of the materials show the band gap 3.75 eV, 2.95 eV, 3.8 eV and 3.0 eV for ZnO, CdO, ZnS and CdS, respectively.
