Opis:
In today’s world the term efficiency gained a status of an imperative at all levels of economic activity (micro, mezo, macro) as well as in all sectors of the economy (private, public, non-profit). The prevalence of “efficiency” in scientific discussions discloses existence of a number of approaches to the understanding of this concept as well as existence of conceptual differences regarding the essence of efficiency, resulting from different ideological foundations of relevant economic theories. This study distinguishes between two analytical approaches: 1) static efficiency – conceptually inscribed in the paradigm of neoclassical economics, 2) dynamic efficiency – developed on the grounds of heterodox evolutionary economics. Within these two theoretical approaches various types of efficiency have been identified and characterized. This resulted in a typology that established a conceptual framework for clarifying different meanings of the term “efficiency”.

Opis:
The article presents selected issues concerning the modelling of the supply chain in the evaluation of the efficiency of tasks realization. In the process of determination, efficiency of the functioning of the supply chain it is necessary to determine the components of both the effects and expenditures in quantitative terms. It is assumed that the effect resulting from action taken depends on the problem under consideration, for example, the result may be the amount of the profits, savings resulting from implemented solutions or measurable improvement of the quality system, expressed e.g. percentage. While the outlay incurred for the implementation of the action is, in general, the expense of implementing this action. The article pointed out that the assessment of the efficiency can be used to decide on the choice of a decision of the many variants of solutions to the problem. In this respect, important are indicators of the efficiency both the technical, economic, quality, and organizational. In the article were also presented possible approaches to improve the efficiency of the supply chain. In the problems of assessing efficiency of functioning of systems with a complex functional structure such as supply, chains increasingly are applicable algorithms based on the so-called heuristics. Hence, in the article briefly have been characterized also chosen heuristic algorithms – genetic algorithms.

Opis:
Efektywność jest pojęciem często stosowanym i wielorako interpretowanym. Funkcjonuje w perspektywie różnych nauk. Powszechnie występujące dookreślenie efektywność ekonomiczna, sugerujące doprecyzowanie tego terminu, nie stanowi też gwarancji odnalezienia jednoznacznej definicji. Różne ujęcia problemów związanych z efektywnością gospodarowania generują potrzebę wielowymiarowego spojrzenia na tę kategorię, także w kontekście społecznym. Niniejsze opracowanie stanowi próbę zebrania i uporządkowania zróżnicowanej interpretacji efektywności ekonomicznej według studiów literatury przedmiotu, jak również zwrócenia uwagi na rosnące znaczenie i potrzebę równorzędnego traktowania niezwykle ważnej efektywności społecznej.
Efficiency is a frequently used and multi-interpreted concept. It functions in the perspective of various sciences. The economic effectiveness that is commonly mentioned, suggesting the clarification of this term, is also not a guarantee of finding an unambiguous definition. Different views of problems related to the effectiveness of management generate the need for a multidimensional view of this category, also in the social context. This study is an attempt to collect and organize a diversified interpretation of economic efficiency according to the literature on the subject, as well as to draw attention to the growing importance and need for equal treatment of extremely important social efficiency.

Opis:
The main focus of the paper is the function of economics in the current application of competition law. While advocating further economization of the law, it is seen as necessary to widen the extent to which aspects of economic efficiency encompassing static and dynamic efficiency are taken into consideration in an antitrust analysis. Much attention is devoted to these issues, while clarifying what is meant by them, how they are to be understood and implemented in the practice of antitrust authorities, as well as discussing their importance for the promotion of innovation. It is noted that accounting for the economic efficiency aspects differently in the light of competition law allows for the assessment of the market behavior of dominant companies, which traditionally has been seen as anticompetitive. This main issue of the paper is analyzed extensively and explained using the case of Microsoft, a company accused by the US and EU antitrust authorities of abusing its dominant position on the market of operating systems in that it integrated the sale of its base product Windows OS exclusively with other applications (Media Player and Internet Explorer). The differences presented in the research part of the paper as to the way Microsoft was treated by these authorities originated in their different methodology of analysis and assessment of the effects of the sales model launched by Microsoft for products offered to the PC manufacturers and their users, in spite of the US and EU antitrust authorities adopting the same evaluation standard – consumer welfare. Aspects of dynamic efficiency adequate in the assessment of the behavior of innovative firms holding a dominant position proved to be deciding. On the other side of the Atlantic, taking into account the aspects of dynamic efficiency was crucial in coming up with a lighter assessment of Microsoft’s tying compared to the European authorities’ assessment which was based largely on the structural analysis, where the benefits arising from dynamic efficiency are not visible. It is clear from the decisions made by the Commission that it favours regulation over effects generated by competition forces at a later time.

Opis:
The aim of this article is to present terminological concerns connected with work efficiency as well as to attempt to define the issue. It is intended to serve as a clarification in the discussion on the practical aspects of work efficiency, including work outcome measurement and high work efficiency systems. Three issues are of prime importance in discussions on work efficiency: What are work outcomes and inputs? How can work efficiency be defined and evaluated? What factors influence the level of work efficiency? Another important question is how to include the social aspects of work efficiency and their consequences on assessing it.

Opis:
This paper analysed the economic efficiency of small-scale tomato farmers in the Greater Letaba municipality of South Africa’s Limpopo Province. Primary data were collected from 68 tomato farmers based on structured questionnaires and using convenience and purposive sampling procedures. The Cobb-Douglas production function was used to analyse the level of economic efficiency. The study utilised the output approach, where the output achieved by the farmers is compared to the maximum output attainable using the given inputs. The empirical results reveal that mean technical, allocative, and economic efficiency levels are at 0.95, 0.41 and 0.39, respectively. The study also found that land (farm size), seedlings, labour, pesticides and water have a positively significant relationship with the production of tomatoes in the study area. Therefore, it is recommended that the Department of Agriculture, Land Reform and Rural Development provide farmers with enough extension services by employing more extension personnel. Government programmes such as the Comprehensive Agricultural Support Programme should be intensified – through the pillar of training and capacity building – to reach the small-scale farmers in the municipality, whereby farmers should be provided with training on the recommended minimum and maximum application of inputs like pesticides, fertilisers, seedlings and water in tomato production.

Opis:
The study presents an important part of fourth chapter of the monograph 'Energy Consumption in Relation to Fuel Efficiency Under Complex Driving Conditions' (2003) concerning opportunities to improve vehicle drive efficiency through application, during one phase of driving in neutral in two-phase driving cycle. Theoretical simulation of total energy consumption in vehicles with SI engine provided explanation of a relatively low fuel efficiency observed under real driving conditions in serial cars [1]. The study cites the original method of calculations developed by the author in order to calculate the efficiency of vehicle power unit in two-phase driving cycle assuming that one of the phases might be non-driving. The calculations were made for complex driving conditions, i.e. simulated changes with predefined steps for road slope (-3.5o to 3.5o), acceleration (-0.36-0.36 m/s2) and average speed (60-140 kmph) for a distance of 2x500 m. The results of calculation variants for each type of a drive system of a car proved that there are significant limitations of optimising the fuel consumption of cars. The first one is conditioned by the fact that the engine works at full dynamic load and the second one by the fact that idle running is against the 'Highway Code'.

Research background: Microfinance institutions (MFIs) play an important role in alleviating poverty. Thus, MFIs should be efficient in order to ensure that their objectives on social welfare and financial performance can be achieved by identifying the potential determinants, specifically on social globalisation. Purpose of the article: This paper examines the impacts of the social globalisation dimensions of interpersonal, informational, and cultural globalisations on the financial and social efficiency of MFIs. Methods: The data period covered the years 2011-2018; the data set consists of 176 MFIs from six Asian countries. The Data Envelopment Analysis (DEA) approach was employed to examine the MFIs' efficiency levels. Generalised Least Square (GLS) regressions were used to analyse the impacts of social globalisation and other determinants towards the efficiency of MFIs. Findings and value added: Interpersonal globalisation had a significantly negative correlation with social efficiency, suggesting that increasing the number of foreigners in management intrudes on local managers' decisions. Informational globalisation had a significantly positive correlation with financial and social efficiency, which signifies that more information produces monopolistic profits in this industry. Finally, cultural globalisation had a positive correlation with social efficiency, demonstrating that a global trading culture improves the abilities and technological skills for labour development and enhances MFIs? social efficiency. In general, the Cobb Douglas Production theory explained the understanding of the impacts social globalisation has on MFI efficiency. Furthermore, the findings from this study could provide important scientific, practical gap and contribute new insights and implications to various parties. Firstly, governments or policymakers can establish effective national policies and strategies. Secondly, this study could support investors in monitoring and understanding the performance of MFIs. Finally, the research could fill scholarly gaps and uncover more potential factors that influence the efficiency of MFIs.

The issue of eco-efficiency is associated with actions aimed at increasing the productivity of raw materials, natural resources and energy savings in production and at the same time offering environmentally friendly products and services. This kind of action is beneficial to businesses and the environment, as well as the society. By reducing the pressure on the environment, caused by production processes, consumption and investment, it is possible to reduce impact of anthropological risks and simultaneously ensuring ecological safety. This article addresses the explanation of the possible connection of eco-efficiency and ecological safety. Considerations include the issue of terminology, as well as key elements of both concepts. The main thesis is: creating solutions for ecoefficiency is associated with ecological safety.

Today’s enterprises, regardless of their size, have to face many new challenges. These include globalization, the use of new technologies and the creation of intellectual capital as a source of the competitive advantage. And moreover the need to act in a changing environment. The organizations must be characterized by a speed of action, flexibility and the ability to learn quickly. They should have employees with high competences who can effectively manage work. The work efficiency management is a business management subsystem. The implementation of this system should take into account not only the material potential, but above all the people. It has a decisive impact on the company’s competitiveness in the market. It allows you to achieve a success. Lawyers are a flexible and dynamic resource that is able to quickly respond to any changes in the company’s strategic goals. Currently, the human resources in the organization are treated as the most precious and the most expensive way. The idea of managing work efficiency is to strive to make the best use of human resources by constantly shaping the engagement and inspiration of people for effective actions for the benefit of the enterprise. A comprehensive approach to work efficiency management is an invaluable tool in building a competitive advantage.

Energy Efficiency (EE) is becoming increasingly important for wireless communications and has caught more attention due to steadily rising energy costs and environmental concerns. Recently, a new network architecture known as Massive Multiple-Input Multiple-Output (MIMO) has been proposed with the remarkable potential to achieve huge gains in EE with simple linear processing. In this paper, a power allocation algorithm is proposed for EE to achieve the optimal EE in Massive MIMO. Based on the simplified expression, we develop a new algorithm to compute the optimal power allocation algorithm and it has been compared with the existing scheme from the previous literature. An improved water filling algorithm is proposed and embedded in the power allocation algorithm to maximize EE and Spectral Efficiency (SE). The numerical analysis of the simulation results indicates an improvement of 40% in EE and 50% in SE at the downlink transmission, compared to the other existing schemes. Furthermore, the results revealed that SE does not influence the EE enhancement after using the proposed algorithm as the number of Massive MIMO antenna at the Base Station (BS) increases.

Zaman and Bulut (2018a) developed a class of estimators for a population mean utilising LMS robust regression and supplementary attributes. In this paper, a family of estimators is proposed, based on the adaptation of the estimators presented by Zaman (2019), followed by the introduction of a new family of regression-type estimators utilising robust regression tools (LAD, H-M, LMS, H-MM, Hampel-M, Tukey-M, LTS) and supplementary attributes. The mean square error expressions of the adapted and proposed families are determined through a general formula. The study demonstrates that the adapted class of the Zaman (2019) estimators is in every case more proficient than that of Zaman and Bulut (2018a). In addition, the proposed robust regression estimators based on robust regression tools and supplementary attributes are more efficient than those of Zaman and Bulut (2018a) and Zaman (2019).The theoretical findings are supported by real-life examples.

Opis:
The article aimed to specify the complexity of assessing the management’s efficiency of research institutes in Poland, in the context of the implementation of tasks resulting from their principal and ancillary activities, as well as other assignments commissioned by public administration authorities. The author attempted to clarify the concept of efficiency by reviewing the subject literature, to find a standard unit to assess research institutes’ activities in terms of efficiency. The analysis carried out based on a literature review, taking into account the complexity of duties of the research institutes, showed that there was no ultimate typology of efficiency, as research establishments have been set up to carry out a broad range of tasks of an economic, social and scientific nature. For that reason, efficiency can be only assessed against the priority, principal, and commissioned tasks implemented by each institute.
Celem rozważań jest przybliżenie złożoności pomiaru efektywności zarządzania instytutów badawczych w Polsce w aspekcie realizacji zadań wynikających z działalności podstawowej, pomocniczej, jak również innych zadań zleconych przez organy administracji publicznej. Autor przybliża pojęcie efektywności dokonując przeglądu literatury łącząc to z próbą znalezienia wybranej jednostki pomiaru efektywności działalności instytutów badawczych. W wyniku analizy literatury oraz złożoności zadań realizowanych przez instytuty badawcze, autor wnioskuje, że nie ma jednoznacznej typologii efektywności, bowiem jednostki są powoływane w celu realizacji różnorodnych zadań o charakterze ekonomicznym, społecznym oraz naukowym. Tym samym efektywność każdego instytutu może być oceniana przez pryzmat priorytetowych oraz podstawowych i zleconych zadań.

Separation Process
Opis:
In mineral processing separation efficiency (SE), operation efficiency (OE), selectivity index (SI) and other indices have been used to evaluate the separation process. Up to now, no study has been conducted on the relationship between the SE, OE and SI indices. In this research, two upgrading curves are proposed based on the above indices for process and selectivity evaluation. The first upgrading curve is based on recovery R, SE, and OE as a function of concentrate grade. This curve has three background lines, including no upgrading line, ideal upgrading line and the ideal mixing line. The proposed upgrading curve is applicable not only for process evaluation by specification of OE and SE, but also for selectivity evaluation with the lowest difference between SE and OE. The curve showed that the recovery value is always greater than the SE and OE values. The parameters of OE, SE and R were used for plotting the upgrading curve as a function of concentrate grade taking into consideration all of them at a time. A new selectivity indicator, namely Efficiency Ratio (ER) as the selectivity parameter, is proposed as the ratio of OE to SE. The ER values fluctuate between 1 and . It can be presented as a function of concentrate and tailing grades (ER = [c(1-t)]/[1(c-t)]). The results showed that ER is insensitive to the feed grade and has the inverse relationship with SI. To measure the separation selectivity, another upgrading curve is proposed based on ER and SI parameters. This curve is divided into seven separation classes for evaluation the class of a separation process from ideal class to no separation one. The results of this research can be useful for separation process evaluation.

Opis:
The Turkish Merchant Shipping Industry has recently witnessed an increasing awareness of the importance to minimize environmental pollution and fuel oil consumption. Together with certain non-governmental organizations and media concerns about environmental protection, the International Maritime Organization (IMO) has been strict on controlling undesirable effects on the environment and, consequently, forcing shipping companies to minimize their emissions. Besides, today’s highly advanced technology companies over the world have developed various innovative systems that can be utilized to minimize carbon emission, thus giving assurance to relevant investors that their investments are most likely to turn out well with a considerable financial gain in the short or long term. Despite all such favorable developments, in a general look, shipping companies seem reluctant in making use of technologies providing efficiency in energy consumption. This reluctance has eventually brought about the term “Energy Efficiency Gap”. This research conducts a questionnaire, created by Acciaro et al. [1], among the shipping companies in Turkey. 20 respondent companies, who represent 26 percent of the Turkish owned merchant marine fleet of over 1000 gross tonnage in terms of deadweight cargo capacity, participated in the research. The Pearson correlation analysis was used, and interpretations were made according to the obtained statistical values. The aim of the research was to identify reasons and points restraining the use of new technologies regarding energy efficiency, as well as to develop proposals for the innovators in this field about how to overcome this handicap concerning technical and managerial aspects of gaining energy efficiency.

Opis:
Poprawa efektywności energetycznej może przynieść wiele korzyści dla gospodarki i społeczeństwa. Jednak programy efektywności energetycznej są często oceniane jedynie na podstawie oszczędności energii bez uwzględnienia niematerialnych korzyści społeczno-ekonomicznych. W rezultacie całkowita wartość korzyści efektywności energetycznej w gospodarkach krajowych i w ujęciu globalnym jest znacząco zaniżona. Zasadniczym celem artykułu jest wskazanie i – na podstawie przedstawionych studiów przypadku – analiza wielorakich korzyści wynikających z poprawy efektywności energetycznej.

Opis:
Aim: This study aims to evaluate the technical efficiency of 44 Brazilian port terminals that handled containers in 2016. The evaluation will first proceed by identifying the main benchmarks. It will then provide an analysis of variables that may have an effect on technical efficiency as well as the nature of their relationship with the latter--namely: container movement and specialized terminals.   Design / Research methods: In this work we apply the techniques of Data Envelopment Analysis and Free Disposal Hull. Output-oriented models were constructed, using three inputs - berth depth, berth length and number of berths, and three outputs - number of containers handled, medium board measured in container handled per hour of mooring, and medium consignment rate measured in container throughput per ship.   Conclusions / findings: The main results show that half of the terminals have an inefficient infrastructure, with capacity larger than necessary to meet current demand for transportation of containers. In addition, there is a strong relationship between the efficiency and size of a terminal port and between the efficiency and degree of specialization. Moreover, the private use terminal of (TUP) Itacal and public quay OCRIM can serve as benchmarks for most of the terminals.   Originality / value of the article: Relatively few works in the literature tried to measure technical efficiency for developing countries. Besides that, none of the works found regarding Brazilian ports have shown the scenario after promulgation of the Port’s Law in 2013, and only a few used container cargo as focus. This article is of interest for scientists of the sector, exporters/importers, and Brazilian Government officers interested in observing the effects of public policies aimed at the sector. We also suggest future work concerning the sector's improvements which can follow from our findings.

Opis:
The paper is devoted to some problems connected with last modification of EU directive on energy efficiency, viz.: free choice of the measure concerning the improvement of energy efficiency, i.e. final or primary energy consumption, corresponding energy savings or energy-consumption index; however without cumulative consumption or cumulative savings of primary energy. In EU directive it has been stressed the importance of measurements systems (reliable measurement information); but has not been recommended any advanced validation of measurements results, nor energy auditing or algorithms of calculating the energy savings due to improvement of energy efficiency concerning large industrial plants. Evaluation of complex buildings should be realized by means of the system method (input-output analysis). The separate problem is devoted to application of thermo-ecological approach in the analysis of complete results of improving the energy efficiency. Human activity is connected with the depletion of nonrenewable resources, including primary energy, due to not only production of consumer goods but also the necessity of compensating the unfavourable effects of harmful emissions from energy-technological processes. Therefore the index of energy-ecological efficiency has been proposed as the most competent evaluation of improvement energy efficiency of production processes and systems.

Opis:
The primary objective of the article was to examine the level and efficiency structure of insurance companies on life insurance market  in Poland. The study presents critical analysis of the insurance literature relating to technical efficiency of insurers, i.e. methods of estimating efficiency, the form of the efficiency  frontier  model, the choice of production factors and insurance production. The study used the methods of mathematical and econometric modelling in SFA  method. The results the technical efficiency study for 22 life insurance companies for a period between 2011-2020 using the SFA method, showed high average cost efficiency of insurers (0.9140) and lower profit efficiency (0. 8565). It was confirmed that a group of large companies achieved higher cost efficiency than the remaining companies, suggesting that large companies benefited from the scale of production.  In contrast, higher average profit efficiency was recorded for the remaining companies.
