Opis:
The article discusses the importance of evaluation in shaping effective public policies. Its purpose is to answer the question of whether and in what conditions evaluations can be a tool for improving the efficiency of public policies. The article has a theoretical nature and is based on studies of both domestic and foreign literature. The analysis presented in the paper shows that from a theoretical point of view the evaluation (along with its methodology and analytical tools) can be an effective instrument for improving the efficiency of public policies. In practice, however, this efficiency mainly depends on such factors as: the model of governance or the mentality of public administration representatives.

Cel: Przedstawienie pojęcia badań ewaluacyjnych. Autorki skupiają się na wykorzystaniu ewaluacji w zarządzaniu, gdzie służy ona podniesieniu efektywności i utylitarności wdrażanych działań. Artykuł przedstawia wzrost zainteresowania badaniami ewaluacyjnymi i zwiększoną częstotliwość ich użycia jako wynik intensywnej praktyki w zakresie wdrażania programów, projektów i innych pomniejszych interwencji w zakresie zarządzania organizacjami. Autorki pragną skłonić odbiorcę do wnikliwszego zapoznania się z pojęciem i wprowadzenia go do praktyki organizacji. Wprowadzenie: W niniejszym artykule pokrótce scharakteryzowano pojęcie badań ewaluacyjnych, jego etymologię oraz specyfikę na tle wyrażeń takich jak „kontrola”, „audyt” czy „monitoring”. Przedstawiono historię ewaluacji – jej genezę. Autorki wyszczególniły podstawowe kryteria ewaluacyjne, a także starały się przybliżyć czytelnikowi, w świetle wcześniejszych informacji, najczęście używane typologie badań ewaluacyjnych. Artykuł ukazuje badania ewaluacyjne jako szczególny typ działań nastawionych na usprawnienie zarządzania. Ich wyjątkowość polega na wieloaspektowości – podejściu do badań nie tylko od strony badanego zjawiska, procesu, ale także na wykorzystaniu kontekstu i silnego sprzężenia na linii działanie – poddani działaniu. W tym kontekście ewaluacja jawi się jako bardzo demokratyczna i egalitarna metoda badawcza, co silnie wpływa na jej użyteczność w praktyce. Wnioski: Od wielu dekad ewaluacja jest użyteczną i przynoszącą wymierne skutki dla procesu efektywnego zarządzania formą praktycznego wykorzystania dorobku nauk społecznych. Badania ewaluacyjne, z uwagi na traktowanie jako ich istoty nie tyle samego działania, co jego silnej korelacji z bezpośrednimi odbiorcami i otoczeniem społecznym, są szczególnym przykładem metody służącej poprawie jakości zarządzania. Ewaluacja jest więc ciekawą propozycją dla praktyków silnie nastawionych na usprawnienie organizacji. Znaczenie dla praktyki: Przedstawienie badań ewaluacyjnych jako możliwości działania w obszarze zarządzania. Zapoznanie czytelnika z podstawową wiedzą w zakresie ewaluacji, jej podstawowych kryteriów i typów oraz kontekstów ich wykorzystania. Dzięki praktycznemu użyciu badań ewaluacyjnych możliwe będzie zwiększenie efektywności procesów zarządzania zarówno od strony merytorycznej, jak i administracyjnej.
Aim: To introduce the concept of evaluation studies. The authors focus on the use of evaluation in management, where the concept is used to increase the efficiency and benefits of implemented actions. The article reveals the growth of interest in evaluation studies and increased frequency of its usage as a result of its intensive implementation in programmes, projects and other lesser interventions within the scope of organisational management. The authors wish to encourage readers to familiarize themselves with the concept and to introduce it within their area of business activity. Introduction: In this article the authors briefly characterized the concept of evaluation studies, its etymology, as well as its specific character in relation to phrases such as “control”, “audit” or “monitoring”. The article presents a history of evaluation, its roots and origins. The authors listed the basic criteria of evaluation and tried to familiarize the reader, in light of prior information, with the most frequently used approaches engaged in evaluation studies. The article presents evaluation studies as a distinctive series of actions aimed at improving management of an organisation. The uniqueness of evaluation study stems from its multi-dimensionality; a research approach, which evaluates a situation from several aspects, not only from the standpoint of observed events or process, but also from the use of context and strong correlation between action, and elements exposed to action. In such circumstances evaluation is seen as a highly democratic and egalitarian method of research, which strongly impacts on its usability in practice. Conclusions: For many decades evaluation, a practical application of achievements in social sciences, has generated benefits and brought measurable results to effective organisational management processes. Evaluation studies, because of their fundamental nature, not only as an isolated activity but in tandem with the strong correlation between beneficiaries and social environment, provides a specific example of an approach, which helps to improve the quality of management. Evaluation is therefore an interesting option for practitioners who are strongly focused on improving an organization. Practical Benefits: Presentation of evaluation studies as a tool, which may be harnessed in the field of management. Familiarise the reader with basic knowledge in the sphere of evaluation studies, its fundamental criteria, types and contexts of use. With the practical application of evaluation studies it will be possible to increase the effectiveness of management processes in terms of decision making and performance.

The conception of an act and its evaluation constitute the most interesting and important moral subject which consists of a complex set of theoretical and practical issues. The article includes St. Thomas’ conception of the definition of the goodness of an act, Tatarkiewicz’s theory of rightness of an act as a source of its evaluation as well as Kotarbinski’s considerations which deal with the analysis of an act from an efficiency perspective. They have all contributed to the definitione of an act in its several variants and provided the possibility of classification of evaluation of an act on the ethical and praxeological plane.

Opis:
Some aspects of discounting of infinite streams of economic quantities (consumption, saving, utility) are considered. The main points of the paper may be summarized as follows. The philosophy of discounting concerns methods of evaluation and/or comparison of multi-period phenomena and processes. The techniques applied (numerical, analytical) may equalize the gravity of subsequent generations or privilege certain generations rather than other ones. They can – to some extent – influence quality of life and the chances of survival in future generations. These (quite natural) connections between discounting and intergenerational justice and sustainability have been pointed out. Systems of axioms for “ethical” and “sustainable” preferences are presented, together with some related (sub)disciplines. Inspirations derived mainly from psychology suggest the modification of the geometric discounting paradigm by slowing down the convergence of discount factors to zero. It should be pointed out that such “heavy tailed” discounting has proved to be useful (and become strongly recommended) for evaluation of a variety of long-time horizon undertakings. Some examples of non-classical discounting rules are given. Finally, the author’s proposal of modeling the duration of the world as a Poisson random variable has been formulated.

Opis:
The study was conducted to assess the effectiveness of wastewater treatment at the municipal wastewater treatment plant in Wolbrom, to which predominantly domestic wastewater and industrial sewage flow. The assessment was made based on the analysis of the physical and chemical research results of raw and treated wastewater. The research was carried out in the period from January 2014 to December 2014. To perform the analysis of the treatment plant efficiency, four indicators of wastewater pollutants such as BOD5 , COD, total nitrogen and total phosphorus were selected for further investigation. For each of the indicators degrees of reduction and coefficients of treatment plant operational reliability were calculated. The calculated degrees of reduction for each of the indicators were high and amounted to 99.0% for BOD5 , 95.2% for COD, 91.0% for total nitrogen and 91.6%. for total phosphorus. These results prove the effective reduction in the amount of pollutants. The determined coefficients of treatment plant operational reliability were at a low level: BOD5 - 0.27, COD - 0.44, total nitrogen - 0.33 and total phosphorus - 0.53. The conducted analyses prove the effective operation of the treatment plant, which was confirmed by high efficiency of pollutants removal.

Opis:
Hospitals are the most important and costly component of the healthcare system. Therefore, hospital performance evaluation (HPE) is an important issue for the managers of these centres. This paper presents a new approach for HPE that can be used to calculate the efficiency, effectiveness, and productivity of hospitals simultaneously. Efficiency refers to the ratio of inputs and outputs, effectiveness refers to the extent to which outputs align with predetermined goals, and productivity refers to the sum of both efficiency and effectiveness. To this end, a Data Envelopment Analysis (DEA) model is developed to simultaneously measure the efficiency, effectiveness, and productivity (DEA-EEP) of hospitals. DEA is a linear programming technique that in its traditional form, calculates the performance of similar decisionmaking units (DMUs) that have both inputs and outputs. In this study, the inputs are the number of health workers, the number of other staff, and the number of patient beds; while the outputs are the bed occupancy rate and the bed turnover rate. A target value is set for each output to measure the effectiveness of hospitals. The advantage of the developed model is the ability to provide a solution for non-productive units so that they can improve their performance by changing their inputs and outputs. In the case study, data of 11 hospitals in Tehran were evaluated for a 3-year period. Based on the results, some hospitals experienced an upward trend in the period, but the efficiency, effectiveness, and productivity scores of most hospitals fluctuated and did not have a growing trend. This indicates that although most hospitals sought to improve the quality of their services, they needed to take more serious steps.

Policja w Polsce jest formacją służącą społeczeństwu i przeznaczoną do zapewnienia bezpieczeństwa publicznego. W interesie społecznym leży sprawna Policja. Miarą utylitarną sprawności działania tej instytucji jest w wymiarze uniwersalnym jej skuteczność w ograniczaniu przestępczości, w tym szczególnie społecznie uciążliwej, oraz wykrywalność sprawców czynów zabronionych. Badając sprawność działania polskiej Policji, dokonano analizy skuteczności jej działań w latach 2015 – 2019.
The Police in Poland is a formation serving society and responsible for ensuring public safety. Efficient Police Forces are in the public interest. The useful measure of the efficiency of the institution’s operation is, in a universal dimension, its effectiveness in limiting crime, including particularly socially burdensome crime, and the detection of perpetrators of prohibited acts. The examination of the efficiency of the Polish Police Forces enabled the author to analyse the effectiveness of their activities performed in the period between 2015 and 2019.

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:
Froth flotation is a dynamic multiphase process in which particulate matter is separated with the help of chemical reagents by gas bubbles immersed in water. The original flotation results are usually presented in the form of kinetic curves relating recovered particulate matter mass (yield ) or mass of a selected component (recovery ), both shortly denoted as y, versus process time t at different concentrations c (g/dm3) of the applied reagents. The kinetic curves can be modified into three: incentive (maximum yield or recovery ymax vs c), limits (ymax vs kinetic constant k or specific rate) and half-life of flotation (t1/2 vs c) curves. The original and modified curves can be normalized by taking into account either an external parameter such as molecular mass (MW), critical coalesce concentration (CCC), critical concentration at the minimum bubble velocity (CMV), dynamic foaming index (DFI), and many other parameters or an internal parameter such as time, concentration needed to achieve certain yield, recovery (y) or kinetic constant. Normalization leads to new flotation curves and provides additional useful information about flotation performance. Normalization can be fully effective, partial or ineffective. Normalization of the original flotation kinetic curves usually is ineffective. Also, normalization of the incentive curve with external parameters such as frother molecular mass, which changes reagent concentration from c (g/dm3) to C (mol/dm3), is also ineffective. Partially effective are normalizations with other external parameters such as CCC and CMV, usually within the same class of regents, for instance alcohols. Only DFI seems to be a universal external normalization parameter for flotation results because it provides fully effective normalization and thus predicts the flotation results. Limited data on DFI restrict a full verification of this hypothesis. Normalization of the modified flotation curves with internal parameters such as k50 (value of 1st order kinetic constant when recovery or yield is 50% after a given flotation time), Ct1/2 (frother concentration in mol/dm3 at which the flotation half-life has an arbitrarily chosen value) and cy75 (frother concentration in g/dm3 at which recovery or yield is 75% after a given flotation time) is a good base for practical classification of flotation reagents.

Hazards identification is essential step in framework of occupational health & safety (OH&S) management system. The task of spruce wood sanding with hand-held power belt sander is considered as a significant resource of exposure to wood dust. Dust from spruce wood is hazard that can cause negative health effects such as asthma and chronic bronchitis. A dust collection box is a commonly used technical measure for reducing exposure to wood dust for this task in practice. The objective of this pilot study was to evaluate the effectiveness of commercially available dust collection box at reducing exposure to wood dust during the task of sanding spruce wood using hand-held power belt sander. Laboratory experiment involved sanding spruce planks (250 mm × 50 mm × 500 mm) in longitudinal direction using belt sander (Bosch, PBS 75 A) with 120 grit sanding belt. Spruce dust mass concentrations were sampled using an aerosol monitor (TSI Inc., DustTrak DRX 8533) in the breathing zone of operator. Inhalable and respirable dust concentrations were both significantly lower (P < 0.0001) when dust box was attached to belt sander compared with sander without a dust box. Results from this pilot study indicate that dust collection box is efficient technical measure for decreasing exposure to aerosol mass concentration during sanding spruce wood with hand-held belt sander.

Data Envelopment Analysis (DEA) is a well-established, popular, and often used method for efficiency evaluation of units from all sector, both commercial and nonprofit organisations, of any scale of operations. Network DEA models are a relatively recent approach used to examine the efficiency of decision-making units (DMUs) having an internal structure of sub-processes. The article presents the concept of DEA network models in estimating the efficiency of courier and messenger companies with relations to their business clients. The considerations are supported by an example of data concerning leaders from the sector of couriers and messengers in Poland and one of the biggest and most popular online stores. The results are compared with the traditional DEA approach. In addition, to measure reliability for DEA scores, the jackknife procedure was performed. The author proves the usefulness of network DEA as a research and management tool.

This study presents an analysis and evaluation of application of European Car Modular Systems in the Polish road transport. Those systems and respective terminology have been analysed and classified. Application of such systems in other countries of the European Union has been described. SWAT analysis has also been carried out in order to enable the most optimal choice of modular system in freight transport to match the condition and characteristics of the Polish road infrastructure. The systems have also been analysed in terms of efficiency and the analysis was performed on the basis of a selected research object – a transport company. An analysis of costs and estimated profits from transport services to be provided by those systems has been carried out on the basis of the research object in comparison with costs borne by the considered company with currently used transport means. This study shows that taking into consideration the results of analyses, safety aspect, road infrastructure and energy efficiency of the vehicles it was found that the proposed oversized vehicles could be implemented to be used on the Polish roads. The analyses and tests performed for a transport logistic company discussed in this article have demonstrated that the proposed modular systems will undoubtedly allow reducing significantly the costs of transport services by increasing load capacity of vehicles.

The approach to forest management has changed many times over the time. Forest receives increasingly a lesser extent as wood and wild game supplier. Social and protective functions of the forest have begun to play more and more essential role. Change in the perception of the forest functions entails the questions about the economic consequences of the forest management in an era of changing priorities. This paper aims to compare approaches to the economic consequences of actions undertaken in the forestry in different periods. The evolution of the approach to the economic analysis can be traced. Analysis of historical publications allows to observe the changes, starting from 1820, when no special attention to the uniformity of drawing income from the forest was paid, through the interwar period, when attempts were made to maximize the profitability of forestry and through the World War II, when no analysis of economic rationality was taken, to the current situation, when more and more attention is paid to the economic consequence of changes in forest management priorities. Presented issues should be a contribution to the discussion on economic issues associated with conducting forest management especially in the context of the tasks included in the forest management plan. It must be noted that, despite the provisions in the instructions for the analysis of forest economic conditions, they often were not reflected in the management plans. Studies aimed at awareness raising and, consequently, the development of the synthetic parameters of an objective description and comparison of the economic conditions of forestry functioning both within the forest district and larger units seem to be necessary.
