In this research, an effort has been made to evaluate the semantic annotators with a systematic subjective evaluation technique. So far, most of the previous evaluation efforts have involved creation of gold standards and by measuring basic metrics, the performance of semantic annotators has been analysed. But in this work, a subjective evaluation technique has been applied to evaluate some of the publicly available semantic annotation systems. In this method, 60 participants have been involved in the evaluation. A survey has been carried out to collect the response from participants about what they think how well the annotators perform on different types of texts (e.g. long texts, short texts and tweets). Their responses have been analysed using standard statistical tests. Using this approach, it has been concluded that Wikipedia Miner performs better on long texts and Tag Me performs better on short texts and tweets than other systems.

The article presents the possibility of identification of rooms on the basis of binaural perception. Results of subjective evaluation were compared with the values of sound strength, G. A previously unknown sound term was introduced: the strength of spatial impression as the inverse of standard deviation of the results obtained. It turned out that the results presenting the sound strength parameter can be correlated with the subjective evaluation of the spatial impression, which is the size of the room. It can be helpful in the process of room identification, probably due to the reverberation impression in the room. Authors plan to continue the study with more rooms and different types of sound sources.

This paper deals with subjective evaluation of audio-coding systems. From this evaluation, it is found that, depending on the type of signal and the algorithm of the audio-coding system, different types of audible errors arise. These errors are called coding artifacts. Although three kinds of artifacts are perceivable in the auditory domain, the author proposes that in the coding domain there is only one common cause for the appearance of the artifact, inefficient tracking of transient-stochastic signals. For this purpose, state-of-the art audio coding systems use a wide range of signal processing techniques, including application of the wavelet transform, which is described here.

Abstract In the work, there was a method of problems examination presented in the certified quality management system according to the ISO 9001 standard. The own method of problems examination was suggested on the basis of reports from audits of the third party. There are method assumptions as well as practical application presented for the examination of nonconformities and weaknesses on a sample of 892 organizations certified by a chosen certifying body. Different types of compilations of obtained results are showed. Different possibilities of their application for the examination of relations of identified problems were indicated, depending on the size and profile of examined organizations. Different types of statistical tests were used in the method together with their possibilities. Concrete examples of uses of the method and statistical tests were provided for examining the relations between the size as well as profile of the organization and the number as well as type of nonconformities and weaknesses. It was attempted to determine what possibilities the method provides and to give the examples of its practical use. Additionally, an attention was paid to potential difficulties when applying the method.

The main objective of this work is to establish whether there are differences in airline pilots’ salaries between the different types of airlines in Europe. With regard to airline type, the companies are categorised into traditional airlines (flag carriers and regular/regional/charter flights) and low-cost airlines. We have examined a total of 176 European airlines and analysed different categories of pilots (Captain Top, Captain Base, First Officer Top and First Officer Base). Two statistical tests were applied (the Haberman test and the chi-squared test) to demonstrate whether there is an association and dependence between types of airlines and pilots’ salaries. The results show that there is association and dependence, from which we can deduce that the earnings of pilots are dependent upon the type of airline for which they work.

This study evaluates the role of antistripping agents to resist moisture-induced damage in asphalt binders. A total of five different types of antistripping agents are used. Plastomer and elastomer modified asphalt binders are used to modify the original base binder. Functionalized and non-functionalized AFM tips are used to determine adhesion in asphalt. With-CH3 tip, lime is found to be the most effective to protect moisture damage in asphalt binder as the adhesion loss is almost zero. The statistical tests show the Pearson values are very close to-1 that indicates a good correlation among the variables. Also the p-values are well below the prescribed value of 0.2% that indicates the test results to be significant from the statistical point of view.

The article presents the results of a study of psychological factors of decision making amongforensic psychiatric specialists. Given the survey data of10 medical psychologists and 10 psychiatrists carrying out compulsory treatment in the psychiatric hospital №5, Moscow Department of Public Health, in comparison with the control group, consisting of professionals working in the field of education, manufacturing, services and technology. Methodical complex included: 1. The Epstein questionnaire of the intuitive style (adaptation Kornilova T. V., Kornilov S. A.); A new questionnaire of tolerance/intolerance to uncertainty (Kornilova T. V.); Melbourne questionnaire of decision making (adaptation T. V.Kornilova); The questionnaire «Personal factors of decision making»(T.V. Kornilova); TheV. Smecalo and V. M. Kucher method; The Tsvetkova Method; 7. The questionnaire «Styles of thinking» by R. Bramsonand Harrison (adaptation of A. A. Alekseev); 8.The questionnaire «Scale of base convictions» (R.Yanov-Boulemane, adaptation M.A. Padun, A.V. Kotelnikov); 9. The check-list aimed to identify the type of decisions taken by the expert in professional activity, their frequency, importance, subjective evaluation is necessary for decision making qualities and to evaluate the most significant opinions of other persons in the decision-making process. There were defined the characteristics of decision making depending on gender. The relationships between type of activity and frequency of occurrence of different types of decisions in professional activities of specialists were revealed. Analyzed the relationship between consideration of the views of others when making decisions and activity.

Purpose Studies have explored expectations of corporate social responsibility (CSR) among cultures, but findings are mixed. A more nuanced view of cultural dimensions rather than using Hofstede’s aggregate country scores can offer a stronger empirical foundation for studying the effects of culture. Based on two cultural dimensions and Carroll’s four-dimensional model of CSR, the purpose of this paper is to test the relationship between individualistic/collectivistic values and individuals’ expectations of different types of responsibilities (economic, legal, ethical and philanthropic), the relationship between long-term values and individuals’ expectations of different types of responsibilities and the degree of skepticism about CSR related to these values. Design/methodology/approach This study surveyed panel participants in two countries, South Korea (collectivistic and long term) and the USA (individualistic and short term), chosen because they are at extreme ends of the cultural values continuum. Multi-dimensional aspects of the cultural variables were tested in the samples rather than using national scores as proxy variables for culture. Data were quantitative and various statistical tests including structural equation modeling were used for analysis. Findings The findings show that horizontal collectivism and the planning dimension of long-term orientation are positively associated with CSR expectations, whereas the tradition dimension of long-term orientation is negatively associated with CSR expectations. In addition, vertical individualism is positively associated with skepticism toward CSR activities. Research limitations/implications The differences in types of individual-collectivism (horizontal and vertical) as well as the different aspects of long-term orientation had an effect on the results, pointing to the importance of exploring the nuances of the dimensions as well as the importance of testing them within the sample rather than using aggregated national scores. Originality/value Previous studies that used a proxy variable for culture assumed that collectivistic cultures have higher expectations for CSR. While empirically supporting the assumption of the relationship between cultural factors and CSR expectations at the individual level, the study found that people who view themselves as autonomous within a group but accept inequality within the group (vertical individualism) are more likely to be skeptical of CSR activities and suggests that skepticism about CSR may be more closely related to individual viewpoints or to particular contexts or particular corporations rather than to cultural factors, which has implications for international corporate communication.

PurposeTo analyze financial inclusion through digital banking in order to identify how digital banking is including or excluding different types of populations in an emergent economy.Design/methodology/approachChi-square statistical tests were conducted to test the relationship between demographic variables (i.e. gender, region, locality and age) with having a digital banking account, types of services and reasons for not using them. As an example of an emergent economy, the Mexican Financial Inclusion Survey database was used, which includes stratified and clustered sampling.FindingsHaving a bank account with digital banking is related to gender. Women are more excluded than men, demonstrating a gender gap in access to digital banking accounts. Moreover, having a bank account with digital banking depends on the region. In regions where digital banking is more developed, the population uses a wide variety of digital banking services, in contrast to less developed regions. About the size of the locality, the lack of financial inclusion via digital banking is more common in rural contexts or small cities, demonstrating the exclusion of this type of population.Research limitations/implicationsThis study is conducted with data from the latest Mexican Financial Inclusion Survey. Since the National Institute of Statistics and Geography (NISG) in Mexico previously conducted the study for exploratory purposes, it was not possible for the researchers to modify the variables.Practical implicationsThe results might be considered on similar emergent economies to promote financial inclusion of vulnerable groups such as women, people living in underdeveloped regions, rural areas, small cities and elders. These findings may provide criteria for both government agencies and banking institutions to make efforts focused on including these population groups that have not been financially included through digital banking.Originality/valueIdentifying the barriers that affect financial inclusion, such as gender, region, size of the city and age can help to guide efforts to achieve greater economic freedom and quality of life for diverse types of populations. Although the study is carried out in an emerging economy, the results can also shed light on how to address these forms of exclusion that occur in different types of economies. It is understood that the lack of financial inclusion is a limitation to the economic freedom and quality of life to which everyone should have access, hence the relevance of the article.

Abstract Although Ecuadorian presidents tolerate most opposition voices most of the time, they routinely try to restrict the basic political liberties of particular critics. In doing so, they initiate executive assaults. Why do some of these executive assaults succeed while others fail? This article analyzes patterns of support for and opposition to publicly contested assaults in Ecuador between 1979 and 2004. Using a combination of statistical tests and a case study, it develops an argument based on the relative power of different types of organizations and associations to influence the outcomes of assault conflicts. The analysis demonstrates that executive assaults fail only when neither the state security forces nor the business sector supports them. In this situation, particular business organizations are able to force presidents to back down. The analysis provides new insights into the social foundations of democratic practice in Ecuador, and Latin America more broadly.
