Abstract
Conceptual definitions are of utmost importance when identifying and describing dimensions and variables needed for conceptual operationalization. That is all the more true for the very fashionable term of resilience considering the litmus test it needs to survive under the constraints and challenges raised by the current Covid-19 pandemics. Consequently, the tenet of this article is that for concepts to become reality, they first need to be translated into formal standards and frameworks guiding action at multiple levels. As a result, the aim of the paper is that, by employing a system based approach and a multi-level investigation into the concept of resilience to lay the minimum grounds for nuancing the definition of resilience at organization level.

STRATEGIC AUTONOMY IN THE CONTEXT OF MULTILATERALISM

Vlad DUMITRACHE

Regional Department of Defense Resources Management Studies, Brasov, Romania
Abstract
The Covid-19 Pandemic has reignited the idea of Strategic Autonomy in the UE. While Brussels has insisted over the last 5 years that Europe should become a major player in defense issues, one has to wonder if the relations with NATO and EU will not change under these circumstances. With the Biden Administration willing to build some bridges with EU it will be interesting to analyze the way the European Union will be able to manage both the development of strategic autonomy while also keeping its multilateral agreements with traditional partners. It is the aim of this paper to analyze the post-pandemic global context into which the UE founds itself and to study the impact that strategic autonomy may have on the member states of the EU, taking into consideration not just defense and security policies, but also economic policies, healthcare issues, the energetic system and the geographical impact that differs for each member state. By doing so we hope to determine what are some way ahead for the EU in its pursue of an increased global player, while becoming a regional leader in the European-Asian and Transatlantic landscape.

Abstract
It is generally believed that high levels of military expenditures hamper economic growth because it crowds out investment. In this study, we investigate how defense spending affects economic growth in the 50 developing countries over the period 2010 to 2016. The results reveal that there is a positive and significant relationship between defense spending and economic growth in the developing countries. It means that, when economic growth, it encourages military sector to spend more, and also population is directly related to economic growth, meaning that when population increase, it rises military expenditure in the developing countries.

AN ALIEN IN A STRATEGIC THINKING WORLD

Paul BEJENAR

Human Resources Management General Directorate, Bucharest, Romania
Abstract
Strategic thinking unleashes the power of leaders on all levels to reach goals, overcome challenges and creatively change the situation from where it is to the desired end-state. All leaders have resources (time, talent and capital) to varying degrees within their organizations. So, technically, all leaders are strategists. The reality, however, is that not all leaders are good strategists. A good leader can evolve in a good strategist by learning how to develop a strategic thinking mindset. Hence, the focus of the current article is on the main ingredients that contribute to the development of strategic thinking.
Key words:
strategic thinking, effectiveness, efficiency, strategy challenges.

*“Lucian Blaga” University, Sibiu, Romania,
** “Nicolae Bălcescu” Land Forces Academy, Sibiu, Romania
Abstract
The concept of time management defines a set of principles, practices, skills, tools and systems that together help a person in an organization to assess what is left at their disposal in order to improve their quality of life. The most important aspect that should be mentioned is that time management does not require a person to learn to do as many things as possible in a short period of time, but it rather ensures that the person does what needs to be done, dealing with the things that really need to be addressed. The ability to manage your time effectively is important. Good time management leads to improved efficiency and productivity, less stress, and more success in life.

Abstract
The economic development of Indonesia and the region has an impact on national maritime security. With these conditions, developments and challenges in the maritime aspect, Indonesia has outlined a policy on the vision of the World Maritime Axis. This vision is a consequence of being a maritime nation with an area that is mostly ocean, as is the policy of Alfred Thayer Mahan (A. T. Mahan). The purpose of this paper is to provide an analysis of the relationship between the vision of the World Maritime Axis (WMA) and the concept of maritime strategy from A.T. Mahan so that it can be seen the relevance of this strategy to the development of President Joko Widodo's World Maritime Axis (WMA) Vision. Based on the results of analysis, the development of the World Maritime Axis (WMA) Vision is relevant to Alfred Thayer Mahan's maritime strategy. The relevance, among others, is that Indonesia is between two continents in the world, namely the Asian continent and the Australian continent; Indonesia is also the largest archipelagic country in the world with a very wide maritime area; Demographic bonus is a condition where the productive age population is more than the non-productive age; History records that the Indonesian people have long controlled sea shipping lanes with a fairly formidable fleet; The vision and mission of the government of President Joko Widodo have the ambition to make Indonesia the world's maritime axis.

ANALYSIS OF CRITICAL FLIGHT REGIMES OF UNMANNED AERIAL VEHICLES (UAVs)

Vasile PRISACARIU

“Henri Coandă” Air Force Academy, Brasov, Romania
Abstract
The aerodynamics of lifting surfaces has undergone a significant evolution determined both by conceptual perspective and by the materials used and related technologies. Accelerating this evolution was also possible due to the use of numerical modeling tools that offered and still offer computational speeds that were not possible a century ago. The constructive concepts of unmanned aerial vehicles (UAVs) offer complex aerodynamic approaches in terms of flight regimes, providing research opportunities on design and manufacturing limitations with direct effects on flight safety. The article wants to highlight critical flight from the perspective of using a freeware tool. The 2D aerodynamic analysis cases of the aerodynamic and 3D profiles of the simple lifting surfaces offer a perspective on the calculation possibilities both through the multiple case studies offered and the expressed results.

Abstract
Indonesia is located in a very strategic position between the continents of Asia and the continent of Australia and the Pacific Ocean and the Indian Ocean, which makes Indonesia a sea line of communication (SLOC) and sea trade route (Sea Lines of Trade / SLOT) for the international world. The size of the Indonesian Navy (TNI AL) territory carried out with the potential threats faced is still not comparable. In order to secure the border areas and maintain the country's sovereignty, President Joko Widodo intends to build the islands of Natuna, Bitung, and Selaru as Aircraft carriers. The Navy can support this desire by strengthening the Naval Bases located in the three regions. Strengthening the Naval Base can be done by analyzing the essential functions and duties of the base and the general requirements of the base. Furthermore, an analysis of the capabilities and technology of weapons owned by the Aircraft carriers of countries in the world can be used as a reference for constructing Indonesian Aircraft carriers. In addition, an analysis of the Naval Base from the Naval Base and Naval Home Base levels is the most appropriate for strengthening to increase the country's deterrence and defense at sea. From the analysis results, three selected Naval bases were determined, namely: Naval Base Ranai, Naval Home Base VIII Manado, and Naval Base Saumlaki.

Abstract
The criminal justice system is at the centre of curtailing radicalization and terrorism. Despite many youths having been arrested, prosecuted or even eliminated, youth radicalization seems to be on the rise which points to the fact that the very criminal justice system contributes to youth radicalization. Anchored on the social identity theory, the criminal justice theory and the psychoanalysis theory, the study investigated the contribution of the criminal justice system to the emergence of radicalization among the youth. A descriptive survey design was adopted. The target population was 320. Stratified simple random sampling was used to select respondents. A sample size of 96 was derived representing 30% of the target population. Both primary and secondary data were used. Validity and reliability of data was tested using Cronbach’s alpha. Data was analyzed and presented using descriptive statistics; percentages, frequencies, means and standard deviations. The research found that police show low level of professionalism while dealing with the problem of radicalization in the study area: suspects are profiled and either arrested and charged in court or arrested and never to be seen again (forced disappearances). That the police do not engage the community when dealing with the problem of radicalization. The study also found out that the legal framework on radicalization and terrorism is a bit weak. The study concludes that the Criminal Justice System is part of the problem of radicalization in the study area. Therefore, there is need for the CJS to change its tactics in solving the problem. There is need to change the hard tactics which are mainly militaristic. The law has to be enforced and those who commit criminal acts must face the full force of the law.
