Abstract

The protection of Polish architectural heritage in the former eastern borderlands, accomplished through the conservation and technical securing of historical structures, constitutes one of the main programmes that are implemented by the Ministry of Culture and National Heritage. Currently, many Polish historical buildings in the former eastern borderlands are in a very bad technical condition. The load-bearing systems of these elements, as well as elements of their finish, require immediate emergency securing work. The basic steps that precede conservation work are emergency structural works, which guarantee the durability and stability of the entire historical substance. The specifics and complexity of the problem of the failure of historical buildings often demands an in-depth analysis of a series of factors that are difficult to measure and which are responsible for the cause and effect relationship during the early stage of the technical evaluation of a structure. The analyses of failures of numerous historical structures, for instance that were carried out by the authors, have become the inspiration for the search for effective methods of analysis that would allow for an in-depth analysis of the causes and effects of the failures in question. The DEMATEL method (Decision Making Trial and Evaluation Laboratory) that has been presented in this work, and its fuzzy extension, has lately become one of the more popular methods used in the cause-and-effect analysis of various phenomena. The authors demonstrated how this method works on the example of the evaluation and securing of the load-bearing system of the XVII Collegiate church of the Holy Trinity in the town of Olykha in the Volhynskiy Oblast, Ukraine.

Abstract

Planning a construction project, the investor frequently faces the choice of the option of the planned investment. Assessment of options is difficult due to the complex nature of construction projects. Various methods of multicriteria evaluation are successfully applied in the assessment and analysis of options. For those methods to work, a handful of information must be prepared beforehand. Among others, it is necessary to establish the assessment criteria and determine their weight for specific cases. This stage is implemented in cooperation with experts. The results of evaluations, obtained on the basis of the experts' opinions, must be processed and prepared. The paper will discuss one possible option for assessing the experts' opinion.

Abstract

Electronic reverse auctions (e-RAs) are considered to be an effective tool for negotiating tender prices and achieving cost savings. Furthermore, if multicritera evaluation is used, it can be expected that e-RAs will also contribute to achieving benefits in other areas, e.g. helping to minimize life-cycle costs. This study aims to analyse the mutual relationships between selected e-RA variables. More specifically, correlation analysis is applied to explore real e-RA data representing public tenders for construction work. This study’s findings reveal that the correlations examined are generally weak or very weak. Furthermore, it has been found that the value of correlation coefficients varies depending on the type of structure, and that public tenders are usually evaluated solely on the basis of the criterion of the lowest bid price. Recommendations for public authorities in using e-RAs in the role of the buyer are also provided at the end of this paper.

Abstract

In 2015 Supreme Audit Office published the report concerned the quality of doctoral studies in Poland. Result of the conducted audit is alarming: “there are serious doubts both about quality and effectiveness of mass doctoral education” (SAO 2015). The text presents an overview of university regulations concerned the evaluation of annual achievements of PhD students (in the area of social sciences) and indicates its potentially negative consequences for the quality of their academic activity. The article refers to two terms – “running for points” and “parametric game”– introduced by Emanuel Kulczycki to describe consequences of economization of research evaluation system, i.e. measuring academic activities and turning them into points-based rewards.

Abstract

The aim of this paper is twofold. Firstly, I present the scholarly book publications patterns of Polish scholars. Secondly, I show how scholarly book publications are assessed in various European research evaluation systems. Moreover, I argue that the diversity of evaluation models depends on the scientific policy aims in a given country. This presentation of European models allows me to discuss a new Polish science policy instrument, that is the list of publishers prepared for the upcoming evaluation exercise in 2021. In 2018, the Ministry of Science and Higher Education in Poland implemented a new model of scholarly book publication assessment based on the list of publishers. On the one hand, such a science policy instrument might be a way to appreciate the best quality scholarly books and give them more points than articles in the evaluation exercise. On the other hand, it is a so far unknown instrument which differentiates publications that have been treated the same up to date. Additionally, this paper aims to shed some light on how the new Polish model was prepared.

Abstract

Quality evaluation is very important for haptic rendering. In this paper, an objective evaluation method for a haptic rendering system based on haptic perception features is proposed. In the method, the haptic rendering process is compared to the real world perception process in a simple standardized procedure based on feature extraction and data analysis. A complete evaluation process for a simple haptic rendering task of pressing a virtual spring is presented as an example to explain the method in detail. Compared with the traditional objective method based on error statistics, the method is more concerned about the consistency of human subjective feelings rather than physical parameters, which makes the evaluation process more consistent with the haptic perception mechanism. The results of comparative analysis show that the method presented in this paper is simple, gives reliable results reflecting the consistency with subjective feeling and has a better discrimination ability for different kinds of devices and algorithms compared with the traditional evaluation methods.

Abstract

In recent years we have interviewed members of the audience after musical performances and asked them to evaluate the acoustics of the concert halls. A group of ‘music lovers’ (with a high level of musical training and experience) and ‘acousticians’ (with a wide knowledge of the physical characteristics of sound transmission) also attended each performance and answered the same questions as the general public. This group thereby served as a control group when evaluating surveys of the general public. In this paper, the results obtained when analyzing these control group surveys are presented. This analysis shows that a common vocabulary exists between music lovers and acousticians when rating a hall, although the grouping of the questions for each factor depends on the training of the respondents.

Abstract

The new evaluation rules proposed by the Polish Ministry of Science and Higher Education in July 2018 are set to cure some of the ailments of the existing system, notably the “punktoza” phenomenon (i.e. publishing for volume, not scientific quality). However, it should be pointed out that the method of fixing old “bugs” might in fact create some new ones. In this article I discuss three elements of the proposed regulations, namely: the principle of “inheritance of prestige”, treatment of chapters in edited volumes, and possible variants of ministerial registry of academic publishers. To address those issues empirically I use an existing dataset covering citation of books in 2009–2013 (Torres-Salinas et al. 2014). While the new evaluation rules apply relatively high value to chapters in edited volumes, they in fact have disproportionately low scientific impact. What is more, the correlation between citation of books and chapters in edited volumes is very low, casting doubt on the assumed “inheritance of publishers' prestige”. Finally, there seems to be a high risk that the registry of publishers will not reproduce the exponential distribution observed in the actual structure of scientific impact (and apparently sought by the new system), thereby jeopardizing validity of such evaluation.

Abstract

B a c k g ro u n d: Arterial hypertension (HTN) ranks among the most widespread chronic illnesses that affect adults in industrialized societies. The main goal of this study was to describe the control (inhibition) processes among HTN patients, and to evaluate the dynamics of brain activity while the patients were engaged in tasks measuring the cognitive aspect of self-control. P a r t i c i p a n t s a n d p ro c e d u re: A set of neuropsychological tests (California Verbal Learning Test, Color Trails Test, The Trail Making Test, Controlled Oral Word Association Test), and a fMRI Stroop test (rapid event design) were administered to 40 persons (20 HTN patients and 20 controls). Groups were matched in terms of age, sex, education, smoking history, and waist-to-hip ratio. R e s u l t s: As revealed by fMRI, the HTN patients demonstrate left-hemisphere asymmetry in inhibitory processes. Also around 90% of patients had problems when completing tasks which rely on verbal and graphomotor aspects of self-control. C o n c l u s i o n s: The results suggest that both cerebral hemispheres must interact correctly in order to provide successful executive control. The deficiencies in control and executive functioning, which were observed among the patients, prove that HTN negatively affects brain processes that control one’s cognitive activity.

Abstract

The Bill defines a requirement which are base of the academic teacher periodic evaluation. The question about criteria, conditions, and instrumentality in the evaluation process should be asked. The investigation was conducted based on 32 evaluation sheets used in 22 Polish universities. As a result the characteristics of the sheets and their construction were displayed. The occupied position or the scientific degree of employee determines the disproportion in the scope of assessment conditions. Another results show main domain which are considered during evaluation of teacher activity. A scientific category of university turned out significant for the scope of an attention paid to these domains. The evaluation sheets were arranged in a typology on the base of their characteristics.

Abstract

Metholodogy of Conclusions Evaluation as a Barrier for Getting Finansing of Innovations in SME. The main aim of this article was to identify the barriers arising from the proposals for the definition of innovation adopted for evaluation. The subject of the study was the methodology of evaluation of applications for co-financing under European Union funds, the sub-measure „Industrial research and development by enterprises”. Complicated procedures and the lack of access to reliable information result in the need to use third-party services when preparing applications. In addition, projects that are highly competitive are favored, but are not always the most innovative. Another problem is the approach to the definition of innovation. The so-called the Oslo methodology was last updated in 2005. The methodology adopted is also not adequate to the current situation in the IT service landscape.

Abstract

In this text are shown the chosen specific manifestations of rhetoric used by NCN experts in the evaluation of grant applications. The subject of analysis are the phrases and expressions contained in the opinions of requests in competitions FUGA (national competitions for internships after obtaining a doctoral degree, postdoc position), which are characterized by ambiguity and commonness. Makes it difficult to incorporate them in re-applying for the grant. Moreover, some of them express patronize attitudes towards potential applicants and their advisors. As an example one could present an expression: „as for pedagogue she has a good achievements”.

Abstract

Activities related to parking of transport, today have become widespread. While parking taxes for vehicles are one of the most important sources of local budgets in countries with established traditions of local government. The tax for parking spaces for vehicles is a relatively new collection in the tax system of Ukraine, which is due to the recent reform in tax legislation. Therefore, the scientific coverage of this subject is currently insufficiently investigated. In the article typical permissive documents are considered when decorating parking lots, and dependence that contradicts the current land legislation affects local revenues to the budget is established. The discrepancy between the general approaches of payment for land is established. For comparison, the approach of parking taxation, for which there is no land management documentation, and the main reason is the permission from the public enterprise for the maintenance of green spaces is considered. The analysis of the current state of the transport scheme of the city shows that in conditions of growth of elaborate road schemes and with insufficient rates of increase in its capacity to contain traffic growth it is advisable to increase the carrying capacity of transport lines and the development of mass passenger transport in cities with a planned increase in average capacity of rolling stock. Also, using traffic management is necessary to ensure that special conditions for the passage of the public transport network.

Abstract

Many business offices around the world are organized as open plan offices. Therefore, studies about the acoustic comfort of the people who work in them have become increasingly important. The focus of this work is the acoustic evaluation of an open plan office combining several architectural characteristics and levels of ambient noise. This evaluation was performed through a computational model calibrated from a real office. The rate of spatial decay of sound pressure levels per distance doubling (DL2) and the speech transmission index (STI) were simulated for the acoustic evaluation of the office, allowing for the determination of the radius of distraction (rD). These parameters were simulated for 6 situations using different floor and ceiling covering materials and inserting or withdrawing screens between workstations. In addition, STI and rD were simulated under two conditions of ambient noise. The results indicated that the DL2 and rD are adequate acoustic parameters for the acoustic evaluation and improvement of an open plan office. The DL2 was strongly influenced by the presence or absence of screens between workstations and by the ceiling covering material. The rD was more sensitive to changes in ambient noise.

Abstract

The main aim of this paper is to present recent knowledge about the assessment and evaluation of low frequency noise and infrasound close to the threshold of hearing and the potential effects on human health. Low frequency noise generated by air flowing over a moving car with the open window is chosen as a source of noise. The noise within the interior of the car and its effects on a driver’s comfort at different velocities is analyzed. An open window at high velocity behaves as a source of specifically strong tonal low frequency noise which is annoying. The interior noise of a passenger car was measured under different conditions; while driving on normal highway and roadways. First, an octave-band analysis was used to assess the noise level and its impact on the driver’s comfort. Second, a Fast Fourier Transform (FFT) analysis was used for the detection of tonal low frequency noise. Finally, the paper suggests possibilities for scientifically assessing and evaluating low frequency noise but not only for the presented source of the sound.

Abstract

The title of the paper harks back to Schopenhauerian ‘der Positivitȁt des Schmerzens’, a formulation which, stripped of its broader philosophical context, reads to most of us paradoxical if not overtly contradictory. The folk (non-medical) perception of pain may be evaluatively negative, but there are also pain conceptualizations which reveal that humans infrequently think about this phenomenon along more positive lines. Thus, being predominantly construed as an ‘evil-doer’, pain does not preclude more positive construals, both in medical and non-medical fi elds. ‘Positivity of pain’, then, is often explored within literary, anthropological, psychological, theological, social, therapeutic and utilitarian realms, and, as Sussex puts it, “in its interdisciplinary span, pain language is a prototypical example of a problem of applied linguistics” (2009: 4). With this in mind, I take a closer look at some verbal as well as verbo-pictorial manifestations of pain. The focus of the present study is specifi cally on the overarching metaphor +PAIN as ‘GOOD-DOER’+ (naturally contrasted with the previously hinted +PAIN as ‘EVIL-DOER’+), further broken into more specifi c sub-metaphors. An attempt at capturing and describing some of these apparently counter-intuitive pain metaphorizations reveals their ‘positive potential’, a potential of tools with which to obtain control over pain and, in many cases, re-forge it into something ‘better’, something evaluatively positive.

Abstract

Development of high-performance finite elements for thick, moderately thick, as well as thin shells and plates, was one of the active areas of the finite element technology for 40 years, followed by hundreds of publications. A variety of shell elements exist in the FE codes, but “the best” finite element is still to be discovered. The paper deals with an evaluation of some existing shell finite elements, from the point of view of the third of three requirements to be satisfied by theelement: ellipticity, consistency and inf-sup condition. It is difficult to prove the inf-sup condition analytically, so, a numerical verification is proposed. A set of numerical tests is considered for shell and plate problems. Two norm matrices and a selection of the stiffness matrices (bending, shear and membrane dominated) are analysed. Finite elements from various computer systems can be evaluated and compared with the use of the proposed tests.

Abstract

The paper presents an approach for evaluation of the likelihood of damage to the transportation infrastructure in the context of the terrorist attacks on the example of a number of bridges located in Wrocław (Poland). Assuming that there will be only one bridge destroyed in a given area, in order to determine the probability of damage to one of the objects, there was one of multi-criteria optimi-zation methods used, i.e. the method of Analytical Hierarchy Process (AHP). The main advantage of the analysis carried out was that the accepted hierarchy of decision-making options could be easily explained in a scientifi c manner, not only with reference to personal knowledge, experience, and intuition.

Abstract

The reliable and rapid diagnosis of infectious animal diseases presents an exceptionally im- portant aspect when considering their control and prevention. The paper describes the compara- tive evaluation of two rapid isothermal amplification methods for diagnosis of African swine fever (ASF). The robustness of loop-mediated isothermal amplification (LAMP) and the cross-priming amplification (CPA) were compared using samples obtained from ASF confirmed animals. Both assays were evaluated in order to define their diagnostic capabilities in terms of ASF diagnosis and reproducibility of the results. Investigations showed no cross-reactivity for other pig patho- gens and no significant differences in the specificity of both assays. The sensitivity of LAMP reached 90%, while that of CPA was 70%. In conclusion, both methods are suitable for imple- mentation in preliminary ASF diagnosis but further improvements are required to enhance their diagnostic sensitivity.

Abstract

Overseas mining investment generally faces considerable risk due to a variety of complex risk factors. Therefore, indexes are often based on conditions of uncertainty and cannot be fully quantified. Guided by set pair analysis (SPA) theory, this study constructs a risk evaluation index system based on an analysis of the risk factors of overseas mining investment and determines the weights of factors using entropy weighting methods. In addition, this study constructs an identity-discrepancycontrary risk assessment model based on the 5-element connection number. Both the certainty and uncertainty of the various risks are treated uniformly in this model and it is possible to mathematically describe and quantitatively express complex system decisions to evaluate projects. Overseas mining investment risk and its changing trends are synthetically evaluated by calculating the adjacent connection number and analyzing the set pair potential. Using an actual overseas mining investment project as an example, the risk of overseas mining investment can be separated into five categories according to the risk field, and then the evaluation model is quantified and specific risk assessment results are obtained. Compared to the field investigation, the practicability and effectiveness of the evaluation method are illustrated. This new model combines static and dynamic factors and qualitative and quantitative information, which improves the reliability and accuracy of risk evaluation. Furthermore, this evaluation method can also be applied to other similar evaluations and has a certain scalability.

Abstract

The article discusses changes in Polish regulations concerning assessment of the climate hazard in underground mines. Currently, the main empirical index representing the heat strain, used in qualification of the workplace to one of the climate hazard levels in Poland is the equivalent climate temperature. This simple heat index allows easy and quick assessment of the climate hazard. To a major extent, simple heat indices have simplifications and are developed for a specific working environments. Currently, the best methods used in evaluation of microclimate conditions in the workplace are those based on the theory of human thermal balance, where the physiological parameters characterising heat strain are body water loss and internal core temperature of the human body. The article describes the results of research on usage of equivalent climate temperature to heat strain evaluation in underground mining excavations. For this purpose, the numerical model of heat exchange between man and his environment was used, taken from PN-EN ISO 7933:2005. The research discussed in this paper has been carried out considering working conditions and clothing insulation in use in underground mines. The analyses performed in the study allowed formulation of conclusions concerning application of the equivalent climate temperature as a criterion of assessment of climate hazards in underground mines.

Abstract

Rockburst is a common engineering geological hazard. In order to evaluate rockburst liability in kimberlite at an underground diamond mine, a method combining generalized regression neural networks (GRNN) and fruit fly optimization algorithm (FOA) is employed. Based on two fundamental premises of rockburst occurrence, depth, σθ, σc, σt, B1, B2, SCF, Wet are determined as indicators of rockburst, which are also input vectors of GRNN model. 132 groups of data obtained from rockburst cases from all over the world are chosen as training samples to train the GRNN model; FOA is used to seek the optimal parameter σ that generates the most accurate GRNN model. The trained GRNN model is adopted to evaluate burst liability in kimberlite pipes. The same eight rockburst indicators are acquired from lab tests, mine site and FEM model as test sample features. Evaluation results made by GRNN can be confirmed by a rockburst case at this mine. GRNN do not require any prior knowledge about the nature of the relationship between the input and output variables and avoid analyzing the mechanism of rockburst, which has a bright prospect for engineering rockburst potential evaluation.
