APPLICATION OF MACHINE LEARNING ALGORITHMS IN PREDICTING CUSTOMER LOYALTY TOWARDS GROCERY RETAILERS
Abstract:
Retailers strive for customer loyalty in the sense of repeat purchases, but also as a high proportion of purchases (compared to competitors) and willingness to recommend to other customers. This paper examines customer loyalty in the grocery sector as a three-dimensional construct and shows how machine learning techniques can be useful in its study. Price characteristics of the retailer (price level, value for money, price dynamics, price communication and price dispersion) and non-price characteristics of the retailer (general product range, retailer's private label product range, store design and atmosphere, service level and location) are included in the model as predictor variables. Using the data collected through the primary research conducted in Croatia, 433 samples were divided into 10 independent predictor variables and one dependent variable (customer loyalty), a prediction was created using supervised machine learning classification algorithms. The Random Forest classifier proves to be the best choice overall, with ROC_AUC value of 0.790, a high accuracy of 0.915 and an F1 score of 0.954, reflecting both precision and responsiveness. The application of the SHapley Additive exPlanations analysis additionally enables the interpretation of the results, highlighting the influence of features on the accuracy of the prediction. The results indicate that price dynamics and service level are the most important features for the model predictions, followed by value for money and price communication.

RESEARCH OF SOME FACTORS AFFECTING DISCRIMINATION IN THE ORGANIZATION
AND ITS IMPACT ON CONFLICT SITUATIONS
Abstract:
The study of discrimination in organizations remains significant. Discrimination leads to various processes linked to conflict situations. In many instances, discrimination stems from the leader's management style. It is also important to consider that any form of discrimination in an organization that causes conflict situations affects the psycho-emotional state of employees, negatively affects their health and personal lives, and ultimately disrupts the work-life balance. The mentioned condition directly affects employee performance. We identified the factors that created significant problems in the relationship between leaders and followers in Georgian organizations. The study was conducted in the Ministry of Economy and its subordinate structural units. Data were collected through an anonymous questionnaire. The developed questionnaire included 64 questions. 720 respondents participated in the survey. Hypotheses were developed and tested using the SPSS statistical package during the research process. Based on the data analysis, important recommendations were developed.

CHARACTERISTICS AND APPLICATION
OF NON-TARIFF INSTRUMENTS
FOR CONDUCTING CUSTOMS POLICY
Abstract:
In order to realize the customs policy of every country, two groups of instruments are used: purely customs instruments - the duty rates for individual products; legally mandated methods for calculating customs values; the application (and lack of application) of the principle of the origin of dutiable goods, and non-tariff instruments that are subject to review by this development.
The aim of the study is to define the characteristics and consider the application of non-customs instruments which in turn can also be resolved into two groups - one for restricting imports, and the other for stimulating exports. These instruments are also used to achieve other objectives which can be economic, fiscal, social and political. Practice in recent years shows that these are used more often to achieve political goals. Furthermore, this happens at the expense of the first three sets of objectives. The reasons are different. The main one among them is the international commitments made by governments and related to their membership in various trade and customs organizations and agreements such as the WTO (World Trade Organisation), WCO (World Customs Organization), and others.
