Personalization and privacy: a survey of privacy risks and remedies in personalization-based systems

Personalization technologies offer powerful tools for enhancing the user experience in a wide variety of systems, but at the same time raise new privacy concerns. For example, systems that personalize advertisements according to the physical location of the user or according to the user??s friends?? search history, introduce new privacy risks that may discourage wide adoption of personalization technologies. This article analyzes the privacy risks associated with several current and prominent personalization trends, namely social-based personalization, behavioral profiling, and location-based personalization. We survey user attitudes towards privacy and personalization, as well as technologies that can help reduce privacy risks. We conclude with a discussion that frames risks and technical solutions in the intersection between personalization and privacy, as well as areas for further investigation. This frameworks can help designers and researchers to contextualize privacy challenges of solutions when designing personalization systems.     

A systematic methodology for kinetic modeling of chemical reactions applied to n‐hexane hydroisomerization

Kinetic modeling provides chemical engineers with a unique opportunity to better understand reaction kinetics in general and the underlying chemistry in particular. How to systematically approach a modeling assignment in chemical reaction kinetics is typically less clear, especially for novices in the field. The proposed modeling methodology pursues an adequate compromise between statistical significance and physical meaning of the kinetic model and the corresponding parameters and typically results in models of an appropriate complexity. It comprises the following activities: (1) data analysis, aiming at qualitative information on the reaction mechanism and corresponding rate equations, (2) model regression to quantify this information via optimal parameter values, and (3) validation of the statistical significance and physical meaning of the parameter estimates. This methodology is successfully applied to n‐hexane hydroisomerization on a bifunctional catalyst. © 2014 American Institute of Chemical Engineers AIChE J, 61: 880–892, 2015     

''I Shot An Arrow in the Air…'' The Performing Arts As Weapons of Social Change

Application of the performing arts as social change agents is illustrated and discussed. Motivations and effectiveness of various groups are exposed and challenged. A review of communication goals and results of the “problem-solving theater” is drawn from recent studies sponsored by the National Council on Crime and Delinquency. Based upon this review, the author poses some characteristics of those enterprises with the greatest promise of effectiveness in the area of resocialization: (1) clients become involved in creative artistic achievement, (2) there are exercises in cooperation and communal activity, (3) there are opportunities for public view and criticism of artistic products, and (4) activities center around adult leadership of stature. The author conclitdes that application of available communication theory calls for programs which change members of “andiences” into participants in meaningful experience.     

Sed qui dicit, non qui negat?

Comments on D. Bramel and R. Friend's (see record 1982-08638-001) article concerning the Hawthorne studies of Western Electric worker attitudes and production. Misinterpretations and invalid conclusions about the work of E. Mayo and G. F. Lombard (1943) and F. Roethlisberger (1939) that Bramel and Friend presented in their paper, dealing primarily with class bias and worker "irrationality," are pointed out.

Promoting form at the expense of content.

Contends that although E. E. Lawler's (see record 1982-31497-001) injunctions about operationalizing the quality of work life (QWL) are invaluable, they raise questions about what is being sold and to whom. One such question relates to the incentive of making money available to help joint union–management QWL committees operate. It is argued that incentives that reinforce bureaucracy are not QWL incentives, and disincentives to mergers of formal bureaucratic channels with grass-roots participation mechanism may not really be disincentives to QWL.

Balance between model detail and experimental information in steam methane reforming over a Ni/MgO-SiO2 catalyst

The optimization and full understanding of chemical reactions is aided by the construction of an adequate kinetic model. The development of such a kinetic model remains a challenging task. To tackle this challenge in the most efficient way, an iterative, systematic methodology, originally demonstrated for n-hexane hydroisomerization, is now extended aiming at finding the balance between the envisaged model detail and available information, often originating from time-consuming and expensive experiments. Steam methane reforming on the Ni/MgO-SiO₂ case study is used for this purpose, that is, the construction of a kinetic model that embeds a maximum amount of information contained in the dataset. The kinetic model is expanded stepwise from a power law model over a model with reactant adsorption toward a Langmuir–Hinshelwood–Hougen–Watson model. The performance of the initially underparameterized model improved significantly by adding reactant adsorption, yet including product adsorption led to overparameterization rather than enhanced model performance. © 2019 American Institute of Chemical Engineers AIChE J, 65: 1222–1233, 2019
