A study of public relations practice in the tobacco industry: misuse and social responsibility
The study\u27s major purpose was to improve the quality and reputation of public relations practice in private industry. The study examined needed improvements m public relations by focusing on the ineffectual and negative practices of the tobacco industry, Also, the study reviewed public and media perceptions of tobacco companies.
The research involved telephone inquiries, information from not-for-profit organizations, and a review of 108 publications using the headings, Public Relations and Tobacco Industry.
Other research included an opinion survey administered to 100 undergraduate students at Rowan College of New Jersey.
Survey results found that a majority of students, smokers, and nonsmokers believed that public relations practice in the tobacco industry was Unfavorable.
Conclusions indicated that unethical public relations practice in the tobacco industry reflected on the reputation of the company and the public relations practitioner. Other conclusions determined that public relations in the industry countered the standards adopted by the Public Relations Society of America.
Recommendations for public relations practitioners were to promote openness throughout the tobacco industry, eliminate tobacco advertisements appealing to teenagers, consider alternative uses for tobacco, and compensation to consumers harmed by tobacco

SUPPORTING TEAM INNOVATION WITH DESIGN THINKING COGNITIVE STRATEGIES
Innovation is a 21st-century skill needed to design new systems, solve challenging problems, and develop novel solutions. Design Thinking (DT) is a tool used to support team innovation. In this experiment, 145 students (47 teams) used one of two DT methods during a semester-long project to come up with an innovative solution to one of the UNESCO 17 sustainable development goals. The key experimental manipulation was during the DT Ideate phase where teams brainstormed potential solutions. Teams either used a baseline DT Ideate strategy or an expanded one with additional prompts during a 10-minute period. Results indicated that teams using the expanded DT Ideate strategy generated 57% more solutions than those in the baseline DT condition. The solutions were content analyzed for innovativeness and the final proposed solutions were rated by other teams. Implications for implementing design thinking are discussed
Towards model evaluation and identification using Self-Organizing Maps
The reduction of information contained in model time series through the use of aggregating statistical performance measures is very high compared to the amount of information that one would like to draw from it for model identification and calibration purposes. It has been readily shown that this loss imposes important limitations on model identification and -diagnostics and thus constitutes an element of the overall model uncertainty. In this contribution we present an approach using a Self-Organizing Map (SOM) to circumvent the identifiability problem induced by the low discriminatory power of aggregating performance measures. Instead, a Self-Organizing Map is used to differentiate the spectrum of model realizations, obtained from Monte-Carlo simulations with a distributed conceptual watershed model, based on the recognition of different patterns in time series. Further, the SOM is used instead of a classical optimization algorithm to identify those model realizations among the Monte-Carlo simulation results that most closely approximate the pattern of the measured discharge time series. The results are analyzed and compared with the manually calibrated model as well as with the results of the Shuffled Complex Evolution algorithm (SCE-UA). In our study the latter slightly outperformed the SOM results. The SOM method, however, yields a set of equivalent model parameterizations and therefore also allows for confining the parameter space to a region that closely represents a measured data set. This particular feature renders the SOM potentially useful for future model identification applications
Dynamically Timed Electric Motor
A brushless DC motor including a housing having an end cap secured thereto. The housing encloses a rotor. a stator and a rotationally displaceable commutation board having sensors secured thereon and spaced around the periphery of the rotor. An external rotational force is applied to the commutation board for displacement of the sensors to various positions whereby varying feedback signals are generated by the positioning of the sensors relative to the rotating rotor. The commutation board is secured in a fixed position in response to feedback signals indicative of optimum sensor position being determined. The rotation of the commutation board and the securing of the sensors in the desired fixed position is accomplished without requiring the removal of the end cap and with the DC motor operating
Physics Potential of Very Intense Conventional Neutrino Beams
The physics potential of high intensity conventional beams is explored. We
consider a low energy super beam which could be produced by a proposed new
accelerator at CERN, the Super Proton Linac. Water Cherenkov and liquid oil
scintillator detectors are studied as possible candidates for a neutrino
oscillation experiment which could improve our current knowledge of the
atmospheric parameters and measure or severely constrain the parameter
connecting the atmospheric and solar realms. It is also shown that a very large
water detector could eventually observe leptonic CP violation. The reach of
such an experiment to the neutrino mixing parameters would lie in-between the
next generation of neutrino experiments (MINOS, OPERA, etc) and a future
neutrino factory.Comment: Talk given at the Venice Conference on Neutrino Telescopes, Venice,
