The role of personnel migration in the introduction of innovations

The study examined the extent of transfer of aerospace management techniques that accompanied the movement of personnel. Sixty individuals who were formerly employed in aerospace were questioned regarding the management techniques they had introduced into their current workplace. In some instances, the information given by the respondent was validated by nonaerospace colleagues. The results clearly demonstrated that the movement of personnel may act as a mechanism for transfer. For all respondents, the mean number of techniques introduced was greater than five. In 13 cases, 100 per cent of the aerospace management techniques currently used were introduced by the respondent; in 15 cases, at least 50 per cent currently in use were introduced by the respondent. The process of introduction was also examined. The managers reported using several steps to encourage transfer including familiarization with the environment, introduction of new goals, adaptation of the technique, persuasion, coercion, and the hiring of co-workers with similar attitudes. The results also indicated that successful innovators were self-confident, had a detailed knowledge of the innovation, were convinced of its value, and were frequently in positions of authority. Finally, results indicated that the introduction was more likely to be adopted in smaller and/or newer institutions, where “discipline” and a team concept existed in management, and when superiors were supportive. Recommendations were made for future research.     

The Domestic Use of Drones: An Ethical Analysis of Surveillance Issues

Drone surveillance can be regarded either as a justifiable, impartial practice serving the interests of all or as an oppressive technique catering to the interests of some at the expense of others. This analysis is an effort to weigh the ethical prospects and problems in the use of unmanned aerial vehicles by asking whether surveillance of civilians is ethical. To address this question, classical philosophical and modern behavioral approaches to ethics are used. The inquiry begins with the importance of the issue, followed by its evolution and current status. After describing the method of analysis, the article examines arguments for and against domestic monitoring. The unique utility of drones can accomplish much in the public interest while simultaneously creating moral hazards. The conclusion discusses accountability standards, model legislation provisions, and regulatory criteria for aerial vehicle surveillance.     

Strontium-90 as an indicator of time since death: a pilot investigation.

The results of a pilot investigation are presented. The study aimed to show that the presence of radioactive strontium-90 in human bone could be used as evidence of active uptake during life. In this way the time since death of the individual could be identified as occurring before or after the date when atmospheric levels of radioactive strontium were at a peak in the early 1960s. The results of this initial investigation were encouraging but further detailed analysis is required on a substantially larger sample of material spanning a more controlled time period.
