Opportunities to optimize the management of aerospace projects

The creation and effective functioning of global satellite systems will allow to create an information base for solving problems related to the regeneration and rational use of natural resources, the creation of a single dynamic model of the Earth, including geological, climatic, biosphere, ecological and social factors. Great attention should also be paid to the problem of increasing the safety of human life in the conditions of the rapid development of intercontinental transport links

Corporate management models

Problems in the management of corporate structures differ from the management of individual organizations, first of all, in content, object of influence, models and mechanisms. The management of corporations is a process related to complex systems in which relations of dependence prevail between units in the system, presented mainly in the form of management and subsidiary organizations. Corporate governance is defined as a system of mechanisms used to achieve and maintain the balance of interests between all participants in the governance process. The effectiveness itself is determined by the use of certain principles in corporate management. The corporation, like any form, is an open system, the management of which should be based on principles common to any economic system

Internet-of-Things Multistatic Passive Radar Station

This paper aims at presenting an Internet-of-things multistatic passive radar station having autonomous and field deployed capabilities. The station is wirelessly connected to a data server and requires, under expected circumstances, no maintenance whatsoever for the projected period of operation. The wireless connection is through radio waves over the Wi-Fi radio protocol making the station an internet-of-things device. A design of the autonomous station is disclosed. Different components are discussed together with their inter-relations. The requirements these components should satisfy, in accordance with the harsh field condition the station is subjected to, are established. The design is supported by three inventions registered at the Bulgarian Patent Office

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

Economic Aspects of the Appraisal and Selection of Engineering Projects

In theory and social practice the choice and appraisal of engineering projects is based on the economic models discussed in this article. The inevitable conclusion is that at the detailed design level the technical parameters prevail, but at system level the economic characteristics and considerations take priority. The recognition of the importance of economic theory and marginal analysis with regard to engineering practice is comparatively new and, because of this, relatively limited. The above dependency ensues from the transition of engineering from designing components and mechanisms to the design of systems. The complex economic appraisal of alternative projects is a critical stage in the process of analysis. This necessitates not only the use of quality indicators but also quantitative methods of risk assessment.

Classifications, Management and Aerospace Methods for Natural Hazards Studies

The last year s world hazardous events (tsunamis, earthquakes, hurricanes, floods, etc.), generated a lot of discussions about the effectiveness of the space research technologies. The introduction of the high technologies in the everyday practice, fast communication systems and recent hardware and software, allows considering that early warning systems can play an important role in the population protection and safety. The concept of the destructive potential is introduced and several classifications about the different natural hazards and their possible negative influences are constructed
