Opis:
To make decisions and exercise managerial control over the degree of input utilization, and produce desired outputs, it is important to assess the efficiency and effectiveness of the municipality-owned public transit service operators. This study uses the Data Envelopment Analysis approach to assess the efficiency and effectiveness of the public transit companies operated by the city administration in Addis Ababa. The size of the fleet and the total number of personnel serve as inputs, and covered vehicle kilometers and the number of passengers carried annually serve as outputs. Based on secondary information gathered from each firm, the technical efficiency and operational effectiveness of service providers are then examined. The study's findings show that the Anbessa city bus was efficient in using resources to produce output in 2019/20 and 2021/22, but wasteful in other years. In the same way, the Sheger City Bus was efficient in 2017/18 and 2021/22 but ineffective in all other years. However, the aggregate findings show that both research's efficiency levels are rising annually. Besides, with mean scores of 0.85 and 0.874, respectively, Anbessa and Sheger Bus were technically flawed. On the other side, operational effectiveness reveals that the Anbessa city bus was only effective in 2021/22. Furthermore, the Sheger city bus' effectiveness result has improved and started to be effective in 2017/18, 2018/19, and 2021/22. In conclusion, the Anbessa and Sheger city buses' efficiency and effectiveness ratings improved year over year and peaked in 2021/22. Hence, to support the business and boost its operational capabilities, the city administration should encourage public bus transit operators in the city and offer subsidies and other incentives to them based on their existing performance.

Opis:
Purpose: The article presents the research results concerning employees’ competencies in JZR Ltd. (Jastrzębskie Zakłady Remontowe Ltd.). Human resources management directly affects the operational results of the activity of a manufacturing company. The managers need to recruit employees possessing a high level of competencies. The key expected result is better economic effects. The JZR Development Programme is a good example of the complexity of processes that should be taken into account in good decisions in the area of human resources management in an activity of a manufacturing company. The main purpose of the research was to identify and analyse key employees’ competencies needed to launch new products on the market. The specificity of machine-building enterprises determines the scope and scale of the necessary activities for efficient and effective human resources management. Design/methodology/approach: The objectives of the research were achieved by the analysis of a recruitment process executed in the JZR Development Programme and a questionnaire survey within the project "Development of the skills ecosystem in four countries of the Visegrad Group". Findings: It was found that key elements determining the productivity level of the JZR Development Programme are the high technical and soft competencies of new employees. A risk analysis is also of high magnificence in so complex and capital-consuming projects. Research limitations/implications: The research limitations are due to the complexity of the system, the difficulties arising from the specificity of the mine environment, the lack of the possibility of ongoing diagnostics of the entire infrastructure (e.g. pipeline specification, the ability to measure sediment in water galleries, smooth change of the speed of drive mechanisms, etc.). Practical implications: The analysed investment programme requires workers specializing in the construction and designing of scraper conveyors, belt conveyors and powered supports. Soft skills such as teamwork skills or knowledge of project management methods and tools are highly needed as well. The activity of JZR Ltd. needs specialized software in the field of machine construction in terms of technology and design. Social implications: The expected requirements are strictly connected with IT skills which should be developed within the education process, especially at technical universities. Manufacturing companies like JZR Ltd. need to participate actively in creating the profile of a graduate at universities. Another possible activity could be achieved by cooperation with a potential candidate for work in a manufacturing company. Originality/value: The value of the research is the identified requirements in the range of analyzed technical and soft competencies which could be treated as a benchmark for similar complex manufacturing development projects. According to what was analyzed in the area of literature review we were able to find, there are no specific studies referring and reporting on employees’ competencies required in projects in mining industry.

Opis:
In emerging countries, improving performance in the transportation industry is a critical concern. Bus transport companies like Anbessa, Sheger and the Public Service Employees' Transport Service play a pivotal role in Addis Ababa's transit system. Subsequently, this study analyzes the operators' operational performance, comparing it to industry norms. The collected data is analyzed using the ratio analysis approach. The findings indicate that the Anbessa City Bus outperforms the other buses in several aspects, such as fleet strength, service utilization, and vehicle utilization, but there is a disparity in staff productivity and operational safety. Sheger City Bus, on the other hand, outperforms the market in terms of vehicle utilization, workforce productivity, and operational safety. However, on most of the indicators, the Public Employees Bus performs the worst. Finally, comparing the operators' performance to industry standards, most indications show that they fail to meet. Consequently, even if bus transit operators are subsidized by the government in the operation of their services for residents, the study suggests that they must make significant improvements in how they use their resources to improve their financial and operational performance and deliver better services compared to those provided by other operators in the city. In addition, government incentives such as subsidies should be allocated based on actual operational performance.

Opis:
Purpose: The aim of the study is to determine changes in the cost efficiency of the administration of public higher education in Poland. Design/methodology/approach: The biennial cost Malmquist productivity index was used to study changes in cost efficiency of 58 public higher education institutions in 2014-2016. The results were presented for 6 groups of universities, according to the Ministry of Science and Higher Education in Poland classification. Findings: The research shows that out of 6 groups of institutions accepted for the study, 2 achieved an increase and 1 a decrease in the Malmquist cost index in both study periods. Changes in the Malmquist cost index in the analyzed period are small as the index ranged from 0.98 to 1.06. Both component overall efficiency change and cost-technical change contributed to the change in the Malmquist index level. Research limitations/implications: The main limitation of the study are the analysis of changes in cost efficiency only. Additionally, only public universities supervised by the ministry responsible for higher education were studied. Future research should include changes in allocative efficiency using the Malmquist index. In addition, a larger research sample should be considered, taking into account other public universities, including medical, arts, etc., and non-public universities. Practical implications: The considerations presented are relevant to public university authorities. The article indicates the need to assess cost effectiveness in evaluating the functioning of a higher education institution. This belongs to the responsibilities of management control in terms of effectiveness and efficiency of HEIs and spending of public funds. Information on the variation of cost efficiency between HEIs, assigned to 6 groups, may become a stimulus to conduct an assessment of this economic category in a given unit and strive to improve it. Originality/value: The added value of the article is the use for the first time of the cost Malmquist index to examine higher education. Also, the use of a modified version of the cost Malmquist index to estimate efficiency assuming variable returns-to-scale.

Purpose: The article concerns the influence of employees’ dynamic capabilities on job performance and the role of e-leadership in strengthening such a relation. Design/methodology/approach: The hypotheses were verified among 1200 organizations operating in Poland, Italy and USA during 2nd wave of COVID-19 pandemic. The statistical reasoning was based on linear regression model with moderator. Findings: The results show that e-leadership is indeed strengthening the positive influence of employees’ dynamic capabilities on job performance, and moreover – such effect is much stronger among organizations operating in crisis during circumstances of COVID-19 pandemic, striving to survive. Research limitations/implications: The empirical research should be treated as a pilot study, as the systemic literature review is limited and has a character of an initial review aiming at the identification of future direction of research in this regard. Practical implications: The obtained results show that organizations, which experience crisis caused by the COVID-19 pandemic are characterized by a much higher level of EDC influence on job performance than those, which do not experience crisis. It is clearly showing the important role of EDC in managing such organizations and transforming their way of doing business in order to survive the crisis. Originality/value: The obtained results contribute new knowledge to the field of job performance management during crisis, confirming that dynamic capabilities are crucial among employees and this specific type of capabilities should be shaped and enhanced among those organizations struggling through crisis caused by COVID-19 pandemic.

Opis:
Extensive research is being conducted to create and use a wide range of alternative fuels to accommodate the world's growing energy needs. The objective of this experimental investigation was to analyze the effects of Karanja biodiesel blends on the performance, combustion, and emission characteristics of a compression ignition (CI) engine vis-a-vis neat diesel. Important physical parameters of Karanja oil were examined experimentally after transesterification and determined to be within acceptable limits. BTE of Karanja biodiesel blends was about 3-8% lower than diesel. For Karanja biodiesel blends, BSFC was about 2-9% higher than diesel but exhaust gas temperature and volumetric efficiency were lower. Emissions characteristics such as nitrogen oxides, hydrocarbons, and carbon monoxide were also analyzed for various tested fuels. Karanja biodiesel blends resulted in lesser CO and HC formation. Nonetheless, NOx emissions were around 10% greater than diesel. Peak cylinder pressure, heat release rate, and maximum rate of pressure rise versus crank angle were among the combustion characteristics parameters considered in this study. Combustion analysis revealed that for Karanja biodiesel blends heat release rate and peak cylinder pressure were lower than for neat diesel. Findings indicate that Karanja biodiesel can be considered a viable diesel engine fuel.

Purpose: There are several factors that affect the satisfaction and performance of virtual and face-to-face teams. Literature shows however, that there is a research gap as to the influence regarding the analysis of those factors in regards to different generations. The purpose of the paper is the youngest generation – Gen Z functions in virtual and face-to-face teams and how the type of team influences the performance and satisfaction of team members. Design/methodology/approach: Adopting a generational approach, a research design, including an experiment and a survey, was developed in order to analyze if the type of teamwork affects performance and satisfaction of Generation Z representatives. Findings: Findings suggest that the youngest, tech-savvy generation functions easier and more naturally in virtual teams, showing no significant differences in performance in virtual and face 16 to-face teams, and even indicate that working in virtual teams is more satisfying than working in traditional teams. Practical implications: The results of the research can provide a basis for managerial decisions when selecting members of real and virtual teams. Originality/value: The paper contributes to the ongoing scientific debate by presenting the perspective of Generation Z on virtual work, which, to a certain extent, contradicts current beliefs about performance and satisfaction in traditional and virtual teams. It shows that the generational approach should be included in team design in order improve team and organizational competitiveness.

Opis:
The results of experimental studies of gasoline mixed with 10% bioethanol (E10), bioethanol mixed with 15% gasoline (E85), and hydrogen– oxygen gas (HHO) supplied as an additional fuel are presented in this paper. Research was carried out to determine whether E85 with hydrogen– oxygen gas is feasible for use as a replacement fuel. During the test, a port injection HR16DE spark ignition engine was used. Experiments were carried out at a constant engine speed (n = 2000 rpm), throttle opened at 15°, using a stoichiometric mixture λ = 1.0 and a lean mixture λ = 1.1. After determining brake torque, fuel consumption data, and energy performance, the results of various fuels were determined. It was found that the highest engine brake torque was developed using E85, but at the same time, fuel consumption increased. E85 yielded the best energy efficiency for a lean mixture (λ = 1.1). A small amount of HHO gas (~ 0.95% energy) yielded a small positive effect only on using E10 fuel at λ = 1.1.

Introduction/background: This paper explores the relation between a concept of project key success factors, popular among project management practitioners, with the operational performance of the project delivered by its team. Aim of the paper: This paper presents research, which answers the question if teams working with the support of project key success factors achieve better performance. Materials and methods: Literature research was conducted, which covered both the subject of team performance and project success. This led to the definition of project team performance and analysis of its relationship with project success. The literature on key success factors was analysed in a historical overview from 1967 to 2020. The empirical research covered the correlation between project success factors and project team performance. Results and conclusions: The analysis of the results showed that each of the team performance components is associated with other group of success factors: project time with collaborative atmosphere (parent organisation-related factors), project quality with professional competence of project team members (team-related factors), project cost with clearly defined objectives (project-related factors).

Introduction/background: This paper identifies and analyzes key considerations in managing online, work-from-home business operations. The literature review summarizes research done both previous to and during Covid-19 shutdowns. An original, international survey, conducted in August 2020, polled managers and professional leaders in multiple industries. Aim of the paper: The best use of our survey is to learn about characteristics of remote work, and possible success factors in managing it, which tend to prevail across industry sectors and geographies. Further, our review of the literature is offered as a concise and practical summary of previous research. Altogether, we hope this paper will serve as a step toward building a wide-ranging, well-rounded body of knowledge on the management of remote work, which will be useful to practitioners and scholars alike. Materials and methods: In August 2020 the authors conducted an international, cross-sector survey that drew responses from 158 individuals. The LimeSurvey consisted of 26 questions exploring organizational responses to the pandemic and how people had been managing the transition to remote work. Along with the structured questions - which typically asked respondents to check one answer from a list of possible replies - there were spaces for open-ended comments. Results and conclusions: Analysis and commentary on survey results has largely been done in the sections above. We would conclude, first, by repeating and summarizing a few key points. Providing technologies and tech support for remote work is necessary, but giving remote workers access to the information they need, when they need it, is mission-critical and may be more of a challenge.

Opis:
Introduction/background: Waste batteries and accumulators are hazardous waste and should not be sent to landfill sites. Their presence in the waste mixture causes the release of dangerous heavy metals into the natural environment. Aim of the paper: The aim of the study is to review the processes currently used in the recycling of used batteries and accumulators, currently used in the world and in Poland, as well as installations and technologies, depending on the types, kinds and physicochemical properties of waste, and to draw attention to the ventures to prevent waste generation. Materials and methods: The paper discusses the nature of waste, storage and transport conditions, organisation of collection, processes and processing technology. The article presents examples of waste management facilities dealing with recovery and recycling of batteries in Poland and Silesia. The research was based on an analysis of legal acts, statistical data, professional literature and company experiences. The second part is a case study. Selected environmental systems presented on descriptive models are based on the results of an environment (region) system analysis. Results and conclusions: EU directives and national law force the reuse of raw materials used in their production. Therefore, one should strive to apply the most effective technologies of waste recovery and recycling. The most recommended and cost-effective is product salvage followed by material recovery, especially of scarce, rare and precious earth metals. Various processes and technologies (installations) for the recovery of raw materials from waste batteries and accumulators are used around the world. The best known are: Jogmec, Batrec, Recytec, Accurec, Everead, Inmetco, Sab-Nife, Snam-Savam, Citron, Batenus, TNO. Long battery life minimises the amount of waste, and thus reduces the burden on the environment. Therefore, in the process of producing batteries, it is important to improve the technology already at the production stage. An example is the Polish experience (Europower; Tuborg; Tuborg-Silver).

Introduction/background: Organizational culture is a relatively new issue. This concept has started to take on a great importance in modern organizations based on knowledge and innovation. The researchers and managers were faced with the problem of how to introduce values into the organization, how to implement the company's mission and vision, how to “manage” employees' creativity, how to motivate and assign tasks to employees. Another important issue concerns measuring the impact of these soft factors on solid results. Is there a relationship between organizational culture and organizational performance and how to verify it? Aim of the paper: The work deals with the topic of organizational culture in theoretical and practical terms. The aim of the work was to define the influence of organizational culture on the management performance. Materials and methods: The work is based on literature studies, the results of literary studies from empirical research and own research of the author. Index methods were used to assess the condition of enterprises based on publicly available financial statements. The research supplements the opinions of employees of these companies. Results and conclusions: In the surveyed organizations, values, relationships and cooperation are put in the first place. Employees work primarily in teams. The aim of this style of work is to improve internal communication, mutual learning and information exchange, as well as stimulating creativity. Regarding the ratio analysis, the good condition of both organizations should be noted: the financial analysis indicators did not deteriorate. It should be stated that organizational performance is influenced by both the dependent variable and the independent variable. They can be analyzed as soft factors and solid factors. The analysis of the impact of these factors can be done using financial measures. The complementary value is constituted by the relations in the organization and the values which make it possible to more effectively implement the company's strategy, mission and vision of the business.

Opis:
There is a need for vehicle relocation, whether for delivering new vehicles to their selling destinations, pulling inoperative or damaged vehicles out of traffiic, or removing illegally parked vehicles from the street. The relocation of illegally parked vehicles in the City of Zagreb is done by constantly monitoring parked vehicles or through citizen telephone alerts. The paper analyses the vehicle relocation service of the Zagrebparking company, which, in addition to overseeing car park management in public car parks and garages, is in charge of removing illegally parked vehicles. Due to the cyclic nature of its operations, a high share of empty rides, high vehicle investment costs, small quantities of cargo transported, high fuel prices, and high fuel consumption in the urban environment, Zagrebparking’s Vehicle Relocation Department operates with unnecessarily high costs. In this paper, vehicle relocation efficiency is analysed by presenting indicators of vehicle utilisation as part of a systematic evaluation of the company. Improvements to the current service are also provided.

Opis:
Purpose: The main reason for developing the model was to fulfil the gap in the scope of synthetic/aggregate measure of corporate innovativeness in terms of company’s results in this area and their impact on its performance. Design/methodology/approach: In the proposed concept two aspects have been considered: quantitative and qualitative results of company’s innovation activity (i) and impact of this results on financial performance of company and its efficiency (ii). Due to the fact, that access to information on innovative activities results of companies is highly diversified, proposed model provides two versions to use: one, more general, based on public sources of data (Public Data Approach) and one, more detailed, based on data which should be collected through survey research (Survey Data Approach). The basis for corporate resultant innovativeness model creation was an assumption, that the ultimate market success of the company is not determined by how many innovative solutions it implements and introduces to the market and with what force it does it, but how these solutions will be accepted by the market and what economic benefits the company will receive due to them. Findings: Proposed methodology of innovativeness assessment gives a chance to eliminate several key shortcomings of the so far used methods and concepts of corporate innovativeness measurement and assessment. Research limitations/implications: Input data accessibility, development of knowledge (rules) bases needed to perform fuzzy inference. Practical implications: Presented model gives an opportunity to assess and compare enterprises in terms of their resultant innovativeness and then to assess the impact of this innovativeness on their performance. Social implications: Assessments generated by presented model can be basis for managerial decisions inside the assessed enterprise or investment decisions of investors in the capital market. Originality/value: Original approach for aggregate corporate resultant innovativeness assessment that eliminates several weaknesses of methods used so far.

Opis:
The use of roundabouts is well recognized for sustaining an efficient and safe intersection. However, the safety results may vary based on the prevailing conditions. Therefore, this study assesses the safety performance of roundabouts in Jordan. This study developed a predictive model by collecting and analyzing all accident records of 12 major urban roundabouts in the country over 3 years. For developing the model, this study employed an accident frequency analysis. The model calculated the rate of accidents and incorporated the geometric and operational characteristics of roundabouts. This was followed by ranking the safety performance of the roundabouts. It was concluded that driver behavior of violating the traffic rules, lack of clear lane markings in the circulating area and inadequate signage at the roundabouts entries are the main causes of roundabout accidents. The research recommends including the developed predictive model in future traffic control and planning studies, for identifying hazardous locations, or for prioritizing roundabout improvements based on safety performance.
