1. "EMPLOYEE PARTICIPATION IN LOGISTICS COMPANIES"
Marcin Pawęska

The article refers to the basic thesis that people (employees) are the most valuable asset of any organisation. In this case, the point of reference are the logistics companies. Some characteristics of the way the TSL industry operates are presented in a very condensed form. This has been used as an argument to emphasise the importance of human resources in these companies; in particular, the importance of intellec- tual capital. Owing to the specific nature of these companies, the need for logistics personnel to be highly competent was clearly emphasised. In fact, this is a sine qua non for staff to be able to actively participate in what is happening in the company, especially in the decision-making process. Not only were the conditions for imple- menting such a management style stressed, but there were also highlighted the ben- efits, especially those resulting from events which are unfavourable for the company.

2. "SELECTED DETERMINANTS OF CONTEMPORARY MANAGEMENT"
Zbigniew Ścibiorek 

This article presents a number of determinants of contemporary organizations which form the basis for the consideration of selected management issues, predominantly those related to soft management. It points out that a company’s human resources are its most valuable asset, and shows how to manage this asset so that it develops and becomes an important element in building the organization’s strategy and position. By highlighting some of the implications of the internationalization of social and economic processes, the need for companies’ employees to continuously improve their professional skills was emphasized. This in turn became the premise for the presentation of a series of conclusions – suggestions which are addressed to science and didactics.

3. "ANTI-LEADERSHIP IN DISPOSITIONAL GROUPS"
Paweł Wasilewski 

Toxic leadership (anti-leadership) in dispositional groups manifests itself at dif- ferent levels of command and control; ranging from competence formation to commandery. It should be noted, however, that in the case of dispositional groups, the tasks are performed under very specific conditions. Working at the limit of one’s capabilities and the threat of losing one’s health and life or, as in the case of the military – taking the lives of others, makes this environment mentally and phys- ically extreme. There is no room for revision when things fail to follow the plan. It is impossible to pause during the execution of a task, to look at it from a different perspective and think of a different way of doing it. The time and events move at an unimaginable speed. Decision making must be, therefore, quick and accurate, and the personnel in charge should be well prepared. Anti-leadership is far more damaging in dispositional groups than in organisations outside them. This makes it all the more important that leaders, commanders and managers are properly selected and properly prepared for their leadership roles.

4. "EXPLANATORY FACTORS FOR THE BALANCE OF CURRENT TRANSACTIONS IN THE CEMAC ZONE"
Jean-Sylvain Ndo Ndong, Ruphin Ndjambou 

Most of the countries in Central Africa have recorded current account deficits since the coronavirus pandemic in 2020. The aim of this article is to identify the main factors explaining the behavior of the current account balances of CEMAC member countries. Using a dynamic panel autoregressive distributed lag (ARDL) model, we use annual data for the period 1970-2018. The results indicate that there is a long- run relationship between the current account balance of the CEMAC countries and the explanatory variables (real exchange rate, terms of trade, domestic savings, GDP growth rate, domestic investment, inflation rate, oil price). We also show that domestic investment boosts the competitiveness of the countries concerned, that domestic savings are directed towards the consumption of foreign goods, that oil revenues do not fuel productive investment, and that there is a structural difference between the CEMAC countries; thus, the terms of trade have an asymmetrical effect on their current accounts. The results of this study lead to recommendations to the effect that diversifying the productive base of CEMAC countries is the most effective way of enabling them to rebalance their current account balances in the long term and reduce their vulnerability to external shocks.

5. "GREEN TECHNOLOGIES PAVEMENT CONSTRUCTION"
Andrzej Surowiecki, Michał Kruszyński, Stanisław Ślusarczyk 

The article deals with the problem of the negative impact of road traffic on the en- vironment. An attempt has been made to justify the need to modify the current technical and material requirements for the construction of road pavements in view of the dynamic growth of road traffic and the increase in freight transport. The atten- tion is focused on the effectiveness of modern and environmentally friendly asphalt pavements. The presented technologies include recycling, polymer modified asphalts, asphalts modified with rubber granules, examples of environmentally friendly pavement constructions and non-standard (also known as “special”) pavements. The article concludes with a summary of relevant practical considerations

Marcin Pawęska, Volodymyr Kahrchenko, Haoyang Li 

The specifics of transport are highly dependent on the type, purpose, and location of the vehicle. Therefore, specific characteristics are determined by a number of very heterogeneous elements. Transport inherently belongs to the category of socio-tech- nical systems with varying degrees of special responsibility. In this regard, the article provides a classification of vehicles. The basic principles of transport organisation in the EU are considered. Attention is paid to the specific features of transport.

7. "GENERAL PRINCIPLES AND METHODS OF TEMPORARY RECONSTRUCTION OF RAILWAY BRIDGES"
Zenon Zamiar, Andrzej Surowiecki 

The purpose of this paper is to discuss the general principles and methods of tem- porary reconstruction of railway bridges. The essence of ad hoc and temporary reconstruction has been discussed. The principles of design of temporary bridges in terms of implementation of engineering design and static calculations in relation to the types of loads and permissible deformations of the span are given. Methods of temporary bridge reconstruction are also presented, and their technique and effectiveness are characterised.

8. "TEMPORARY BAYS DURING RECONSTRUCTION OF DESTROYED RAILWAY BRIDGES"
Zenon Zamiar, Andrzej Surowiecki 

The subject of this article is provisional spans used in cases of ad hoc and temporary reconstruction of damaged or destroyed railway bridges. The general principles of tempo- rary bridge reconstruction are given, as well as the purpose of using these spans and their classification. The following provisional spans were characterised in terms of construction and installation technology: lattice spans (folding and fixed), spans made of steel I-beams, load-relieving structures (bridge type and made of railway rails) and spans made of wooden beams. Attention was drawn to the need to try to use the existing structural elements of the damaged bridge as much as possible.

9. "9. CONTROL AND ALLOCATION AT AN INTERSECTION WITH TRAFFIC LIGHTS"
Dominik Malinowski 

Managing road infrastructure in highly urbanized areas during the Industry 4.0 era poses a significant technological challenge for traffic engineers. Steadily growing traf- fic volume, both of motor vehicles and pedestrians, cyclists or scooters, necessitates the development of advanced traffic control algorithms and systems. Improvement of the efficiency and capacity of intersections without any intervention into the phys- ical structure of roadways is one of the two aspects of today’s traffic engineering. In this paper, however, emphasis is placed on the aspect of coordination of conflicting flows of motorized and pedestrian traffic. Consideration is given to ensuring that each traffic light phase at an intersection is maximally utilized while maintaining the required safety factor. The empirical part of the study consists in identifying inefficiencies in the traffic light cycle. The analysis of traffic phases has revealed that there were certain periods in the cycle during which pedestrians were given the right of way while, in fact, it was not necessary. The study proposes a solution to optimize the green signal timing for conflicting vehicular and pedestrian flows in real-time. By eliminating delays in traffic signal phases as a result of not having to give a green signal for pedestrians, the proposed solution will improve the effi- ciency of urban networks with respect to an aspect whose potential has not been exploited so far. Coordination and adaptation of each light phase to the most effective extent is a feasible answer to the needs and requirements of modern urban areas.
