The Arab Spring

Since late 2010 and early 2011, the Arab region has witnessed mass protests in Tunisia, Egypt, Libya, Syria, Yemen, Iraq, Bahrain and other countries that have been referred to in the political, media and other literature as the Arab Spring. These movements have had a profound effect on the stability of the regimes Which took place against it, as leaders took off and contributed to radical reforms in party structures and public freedoms and the transfer of power, but it also contributed to the occurrence of many countries in an internal spiral, which led to the erosion of the state from the inside until it became a prominent feature of the Arab) as is the case in Syria, Libya, Yemen and Iraq.

The Impact

One of the main criteria for economic development is the size of the public debt and its dynamics. The article considers the impact of public debt on the financial security of Ukraine. The views of scientists on the essence of public debt and financial security of the state are substantiated. An analysis of the dynamics and structure of public debt of Ukraine for 2014-2019. It is proved that one of the main criteria for economic development is the size of public debt and its dynamics. State budget deficit, attracting and using loans to cover it have led to the formation and significant growth of public debt in Ukraine. The volume of public debt indicates an increase in the debt security of the state, which is a component of financial security. Therefore, the issue of the impact of public debt on the financial security of Ukraine is becoming increasingly relevant. The constant growth and large amounts of debt make it necessary to study it, which will have a positive impact on economic processes that will ensure the stability of the financial system and enhance its security.

Party State

Zambia inherited a system of government and administration in 1964 which was ill-suited to the tasks of political development to which her new leaders were dedicated. What little national unity and mobilisation had been achieved in the independence struggle declined with the removal of the common enemy. The Government rested on a fragile base, without the support of agreed rules and practices to limit and contain conflict, and without adequate instruments available for the implementation of its policies. So the search began for a more suitable political system, which could cope with the new needs of independence, and provide for the stability of the state and the survival of the Government.

Security Concern

Deepening globalisation and worldwide availability of free information and ideas raise concerns of the communist China’s political leadership about the stability of the regime and the sustainability of the state ideological orthodoxy. Therefore, the state’s tightening control of the public communication to curtail the domestic criticism and occasional public discontent is becoming framed and legitimised in terms of cultural security as a non-traditional security concern. This study argues that the restrictive impacts of the politicisation of culture in the centralised agenda of President Xi Jinping reinvigorate China’s anti-Western narratives and attitudes. The research focuses on the state’s cultural security-related and applicable strategy in the political and institutional agenda and media. Moreover, the study also traces the state cultural security policy in the field of the civic and non-governmental sector, religious and ethnic minorities policy, literature, film and audiovisual sectors. The findings assess the concern that the intellectually anachronistic, self-restraining and internationally hostile policy devaluates China’s cultural potential and complexity.

PurposeThe aim of this research is to design a robust active disturbance attenuation control (RADAC) technique combined with an extended high gain observer (EHGO) and low pass filter (LPF).Design/methodology/approachFor designing a RADAC technique, the sliding mode control (SMC) method is used. Since the standard method of SMC exhibits a chattering phenomenon in the controller, a multilayer sliding mode surface is designed for avoiding the chattering. In addition, to attenuate the unwanted uncertainties and disturbances (UUDs), the techniques of EHGO and LPF are deployed. Besides acting as a patch for disturbance attenuation, the EHGO design estimates the state variables. To investigate the stability and effectiveness of the designed control algorithm, the stability analysis followed by the simulation study is presented.FindingsThe major findings include the design of a chattering-free RADAC controller based on the multilayer sliding mode surface. Furthermore, a criterion of integrating the LPF scheme within the EHGO scheme is also developed to attenuate matched and mismatched UUDs.Practical implicationsIn practice, the quadrotor flight is opposed by different kinds of the UUDs. And, the model of the quadrotor is a highly nonlinear underactuated model. Thus, the dynamics of the quadrotor model become more complex and uncertain due to the additional UUDs. Hence, it is necessary to design a robust disturbance attenuation technique with the ability to estimate the state variables and attenuate the UUDs and also achieve the desired control objectives.Originality/valueDesigning control methods to attenuate the disturbances while assuming that the state variables are known is a common practice. However, investigating the uncertain plants with unknown states along with the disturbances is rarely taken in consideration for the control design. Hence, this paper presents a control algorithm to address the issues of the UUDs as well as investigate a criterion to reduce the chattering incurred in the controller due to the standard SMC algorithm.

The mass introduction of information technologies in the activities of state structures has made it possible to transfer the efficiency of their functioning to a qualitatively new level. Unfortunately, as a means of action, they have characteristic vulnerabilities and can be used not only for good, but also for harm. For the state, as a guarantor of the stability of a civilized society, the issue of ensuring the security of information processing is particularly important. Despite the automation of many information processes, the most vulnerable link in the work of information systems remains a person. A person acts as an operator of information systems and a consumer of information. The entire service process depends on the competence of the operator and the quality of his perception. There are areas of government activity where the cost of error is particularly high. These include ensuring the life and health of citizens, protecting public order and the state system, and ensuring territorial integrity. The specifics of the spheres must be taken into account when ensuring the security of information. This study concerns official activities that are provided by paramilitary groups. Currently, there is a discrepancy in the level of competence of new personnel in the first months of service. The author traces the shortcomings of general and special professional qualities in the field of information security. The purpose of the study is to substantiate certain pedagogical means of forming cadets ' readiness to ensure information security. As forms of theoretical knowledge, we will use the traditional hypothesis and model, as well as functionally distinguishable judgments – problem, assumption, idea and principle. Empirical forms of knowledge will be observation (experimental method) and fixation of facts. To evaluate the effectiveness of the developed pedagogical tools, we use statistical methods: observation (documented and interrogated) and calculation of generalizing indicators. To formulate conclusions, we will use logical methods: building conclusions and argumentation. The approbation of certain pedagogical tools described in this article showed a significant positive trend in terms of competence in information security issues.

As of December 2020, since the beginning of the year 2020, the COVID-19 pandemic has claimed worldwide more than 1 million lives and has changed human life in unprecedented ways. Despite the fact that the pandemic is far from over, several countries managed at least temporarily to make their first-wave COVID-19 epidemics to subside to relatively low levels. Combining an epidemiological compartment model and a stability analysis as used in nonlinear physics and synergetics, it is shown how the first-wave epidemics in the state of New York and nationwide in the USA developed through three stages during the first half of the year 2020. These three stages are the outbreak stage, the linear stage, and the subsiding stage. Evidence is given that the COVID-19 outbreaks in these two regions were due to instabilities of the COVID-19 free states of the corresponding infection dynamical systems. It is shown that from stage 1 to stage 3, these instabilities were removed, presumably due to intervention measures, in the sense that the COVID-19 free states were stabilized in the months of May and June in both regions. In this context, stability parameters and key directions are identified that characterize the infection dynamics in the outbreak and subsiding stages. Importantly, it is shown that the directions in combination with the sign-switching of the stability parameters can explain the observed rise and decay of the epidemics in the state of New York and the USA. The nonlinear physics perspective provides a framework to obtain insights into the nature of the COVID-19 dynamics during outbreak and subsiding stages and allows to discuss possible impacts of intervention measures. For example, the directions can be used to determine how different populations (e.g., exposed versus symptomatic individuals) vary in size relative to each other during the course of an epidemic. Moreover, the timeline of the computationally obtained stages can be compared with the history of the implementation of intervention measures to discuss the effectivity of such measures.

<p class="Abstract">The purpose of this study was to determine the model of a interaction system between the DNA with protein. The interaction system consisted of a molecule of protein bound with a single chain of DNA. The interaction between DNA chain, especially adenine and thymine, and DNA-protein bound to glutamine and adenine. The forms of these bonds are adapted from the hydrogen bonds. The Cornell potential was used to describe both of the interactions. We proposed the Hamiltonian equation to describe the general model of interaction. Interaction system is divided into three parts. The interaction model is satisfied when a protein molecule triggers pulses on a DNA chain. An initial shift in position of protein xm should trigger the shift in position of DNA ym, or alter the state. However, an initial shift in DNA, yn, should not alter the state of a rest protein (i.e. xm = 0), otherwise, the protein would not steadily bind. We also investigated the stability of the model from the DNA-protein interaction with Lyapunov function. The stability of system can be determined when we obtained the equilibrium point.</p>

Abstract: The economic elements are of great importance to the componential structure of the Malaysian society. Moreover, the economic structure represents one of the major elements of a state might. The economic potentials of a state include whatever resources it has or whatever it can get to achieve its strategies or the self-sufficiency of its people in wartime. In peacetime, on the other hand, the state should depend on a strong economic base that helps achieve a completion to its parts and a basic element of its internal political integrity. Accordingly, the various types of the economic resources with respect to the production, exchange, and consumption represent one of the influential factors that affect the political behavior of a state- the way of its thinking, saying, decision-making, and actions. Much of the political behavior of a state comes from its economic background within its territory. However, the factor that plays a significant role in determining the actual might of a state is the number of population a state has and its ability in investing its resources. From this vantage, Malaysia represents one of the economically rich countries owing to its various natural resources. Furthermore, both trade and transport help a great deal in redistributing the economic resources of Malaysia. For the latter importance, the present work is to showcase in detail the role the economic factors play in achieving the stability and integrity of Malaysia and its people. Besides, it sheds light on the impact of ethnic diversity and the strategic position in the world on the overall stability of the state.

The purpose of the article is to clarify the external functions of the President of Ukraine in the context of ensuring the security of the state. The mechanism of performing the external functions of Ukraine is characterized by the complex structure of interrelated and interacting relations. Of particular importance in this mechanism is the President of Ukraine, who, in accordance with the powers enshrined in the Constitution of Ukraine and Ukrainian legislation, heads this mechanism and coordinates the operation of its parts. The foreign policy activities of the President of Ukraine are based on the general principles of separation of powers, of the rule of law, of constitutional responsibility, and on the specific principles of the unity and of the support of foreign policy. In order to improve the operation of the mechanism of implementing foreign policy, headed by the President of Ukraine, the measures aimed at intensifying foreign policy activities and enhancing the independence of the Government of Ukraine and developing the scientific component of this mechanism are required. The process of performing external functions of the state implies the existence of an appropriate mechanism. The mechanism of performing Ukraine’s external functions includes elements that are heterogeneous in their task, legal status, organization and other characteristics, which in their turn are interrelated and interacting. The President of Ukraine has a special place in this mechanism. In accordance with the Constitution of Ukraine, he directs the foreign policy of the country and as a head of state represents Ukraine in international relations. The logic of the current stage of the development of interstate relations strongly confirms that in order to effectively strengthen the common peace and international security, a unified strategy of interacting and regulating the external functions and powers of the presidents at the international level in ensuring this security must be developed. Perhaps, one of the most important functions of the President of Ukraine at the international level is the external function of ensuring the security of the state. Until the state has the security of its own territory and borders, other functions do not matter, because security is the guarantee of the stability, and therefore, the possibility of ensuring other functions.
