Author(s): Jelena Lukić Nikolić,Branislav Dudić,Vladimir Mirković / Language(s): English Issue: 1-2/2024

In the digital age, various concepts and activities of organizational agility and employee engagement should be observed from different perspectives and adapted to a new way of doing business that requires a fast response to all changes in the environment. Understanding the impact of employee engagement on organizational agility is a “conditio sine qua non” for the long-term success, growth, and development of any organization. The aim of this paper is to examine and analyze the key implications of employee engagement on organizational agility in the digital age. Research was based on case study method in one software development company from the Republic Serbia. Interview technique was applied for data collection. The analysis of qualitative data collected during May 2023 showed that engaged employees from the technical support department represent the lever for organizational agility. During their work, technical support consultants receive valuable information from clients, and they are the first in the chain that point out needed software improvements and changes. A high level of employee engagement is important for organizational agility, which refers to the ability of an organization to respond and react quickly and effectively to the external and internal changes, and to adapt to those changes in a profitable way

Predicting UK Housing Price using Machine Learning Algorithms

Author(s): Gbadebo A. OGUNDEJI,Dilkushi de Alwis PITTS,Yeran SUN,Mubeen GHAFOOR / Language(s): English Issue: 1(5)/2024

The development of reliable predictive algorithm for house price as the housing market is a stand-out among the most involved regarding valuing the price and continues to fluctuate, is constantly a need for socio-economic advancement and welfare of citizen. In this paper, we develop machine learning algorithms for forecasting UK housing Price, and find an optimal algorithm that forecasts housing price accurately on the premises of the presence of many features or covariates. After applying correlation analysis to remove correlated variables in order to avoid multicollinearity, thereby increasing the statistical power, a novel method of using regression analysis to first of all understand and select statistically significant features for the various regions in England based on North South divide is adopted. These features are then used in the machine learning algorithm to further increase the statistical power of the algorithm, increase the level of accuracy for each of them and ultimately increase the predictive values for the algorithms.The model construction involves 3 stages: 1- correlation analysis to identify and remove correlated variables thereby avoiding multicollinearity and increasing the statistical power of the linear regression, 2 - using linear regression to determine variables that are statistically significant and 3 - building the machine learning algorithms based on the variables that are statistically significant from the linear regression. A comprehensive dataset of UK Paid housing Price from 2010 to 2019 was linked to a number of other datasets to generate a total 21 variables or features used for the models. Catboost, Gradient Boosting, Bagging, Random Forest, Extra Tree all achieved the excellent model’s performance result in all the regions considered. The comparison of the seven models showed that Extra Tree algorithm consistently achieved the best performance in term of level of accuracy in all the regions. K-Nearest Neighbours (KNN) is the only algorithm with less than 50% level of accuracy. Noticeably, the regions considered had varying or differing insignificant variables, implying that although many variables are common (statistically significant) to all the regions, there are regional differences and impact when modelling or predicting housing prices. This study validates the practicability of developing a machine learning methodology for the prediction of housing price. This research offers a reference for future house price prediction based on machine learning.

Comparative study on remote work regulation in public administration in Romania and France

Author(s): Georgiana Mădălina Mihăilă / Language(s): English Issue: 11-11.2/2023

Remote working is a topic that has gained momentum in recent years in both the private and public sectors. Even if this concept was not new in the private sector, policies to implement telework have been accelerated in all fields in the context of the epidemiological crisis caused by the SARS- COV-2 virus. The year 2020 has thus therefore brought about a paradigm shift in the global economy in terms of the way employees work, with the effects also visible in public administrations around the world. Remote working, also known as telework, has both advantages and disadvantages. While in the private sector each employer is free to develop its their own policies on telework, public administrations have had to regulate the concept in order to prevent possible negative effects and to ensure fairness, balance and unity across all their bodies. Adapting to new ways of working has been a priority in countries such as France, and the similarity of the administrative systems in the two countries creates the necessary prerequisites for a comparative study based on content analysis. The subject of telework in the public sector is also important from a human rights perspective, as the issue of differential treatment and benefits for employees in the private sector compared to the public sector has been raised, which could also lead to reluctanceto take up positions in public administration.

LEGAL CHARACTERISTICS OF THE RESTRUCTURING PROCEDURE IN THE REPUBLIC OF SRPSKA

Author(s): Sladjana Kosmajac / Language(s): English Issue: 40/2024

Restructuring is a rather extensive and specific legal institute. In everyday speech, it means to rearrange something. In the legal sense, restructuring can be understood in many ways. In the economic sense, it is about technical-technological changes within the business entity. In the second context, restructuring is any form of change within a business entity, while in the third context, it is a status change specified by business regulations. In addition to the above, restructuring is possible in bankruptcy proceedings, i.e. before the grounds for bankruptcy have been established, then simultaneously with the initiation of bankruptcy proceedings and later through a specified plan by which the debtor will be restructured in a way that even though the grounds for bankruptcy have been met and bankruptcy is started, and the debtor will stay in economic life. The purpose of this paper is to give an explanation of and key differences between all the institutes above. In this paper, we will also make suggestions about the need for a clear demarcation in terms of understanding restructuring, so as not to create doubts in the legal and economic life of the Republic of Srpska

ANALYSIS AS AN EXECUTIVE FUNCTION OF THE INTELLIGENCE-LED POLICING IN THE REPUBLIC OF SERBIA

Author(s): Ilija Racić,Siniša Dostić,Kristijan Šebešćan / Language(s): English Issue: 40/2024

The goal of this research is to identify, scientifically describe, classify and partially explain weaknesses in the application of analysis as an executive function of the Intelligence-led policing model in the Republic of Serbia using scientific research methods. The conducted theoretical research identified problems of a functional nature using the executive function of analysis, which can be classified as follows: 1) traditional (reactive) way of applying analysis about modern proactive models using modern analytical tools, 2) differences in the theoretical definition of data analysis and information, 3) the quality of entered statistical indicators in electronic databases. The executive functions of the Intelligence-led policing model are performed through the criminal-intelligence process, which is an evidentiary tool for analyzing the actions of all forms of criminality, misdemeanours and other security-interesting incidents and enables decision-making based on the collection, processing and analysis of data, as well as the undertaking of preventive measures. A key role in law enforcement intelligence operations is the application of the analysis function, which leads to the improvement of quality based on the previous functions (collection and processing), which contributes to the greater use value of data in further work of criminal police. The research was carried out as a theoretical-empirical one, where the methods of theoretical and empirical research (attitudes and opinions of police officers in the police of the Republic of Serbia) were used, that is: general scientific, logical and empirical methods. In this research, the standpoint that the analysis function can be improved is confirmed both theoretically and empirically, which requires the following (functional) changes: 1) it is necessary that the analysis be carried out using modern analytical methods, such as AnaCap, OIAT, risk and threat analysis, with focus on proactivity, which affects the efficient and effective creation of analytical products; 2) the quality of statistical data entered into electronic databases and the amount of prepared operational reports and information predominantly influence the application of the analysis function and the quality production of analytical products. The scientific justification of the research derives from its expected results, which can: 1) contribute to the deepening and expansion of scientifically verified knowledge in the field of criminal-police, security and organizational scientific disciplines, 2) indicate the directions, areas and topics of future scientific research and 3) enrich the methodological practice of scientific research on the organization and proactive functioning of the police in modern conditions.
