The use of algorithms is beginning to replace human activities in the news business, and the presence of this technique will only continue to grow. The ways in which public news readers perceive the quality of news articles written by algorithms and how this perception differs based on cultural conditioning remain issues of debate. Informed by the heuristic-systematic model (HSM) and the similarity-attraction theory, we attempted to answer these questions by conducting a three-way one-way analysis of variance (ANOVA) test with a 2 (author: algorithm vs. human journalist) × 2 (media: traditional media vs. online media) × 2 (cultural background: the US vs. South Korea) between-subjects experiment (N = 360). Our findings revealed that participants perceived the quality of news articles written by algorithms to be higher than those written by human journalists. We also found that when news consumption occurs online, algorithm-generated news tends to be rated higher than human-written news in terms of quality perception. Further, we identified a three-way interaction effect of media types, authors, and cultural backgrounds on the quality perception of news articles. As, to the best of our knowledge, this study is the first to theoretically examine how news readers perceive algorithm-generated news from a cultural point of view, our research findings may hold important theoretical and practical implications.

Research Findings

Climate change represents one of the major challenges of our century with great potential to alter water quality, and hence, find suitable solutions becomes a must. Stanca–Costesti reservoir is one of the most important in Romania and one of the most affected by the hydrologic variability. The studies regarding the trophic state of this reservoir are few, even if there are some environmental issues in its hydrological basin that could be further investigated. According to the National Administration “Apele Romane” (ANAR) yearly reports, the Stanca–Costesti reservoir is, from the trophic state point of view, an oligotrophic lake. The current research is based on chemical and some biological data collected over 10 years (ANAR) for the trophic state of the Stanca–Costesti reservoir, using the Carlson index. The research investigates the hydrological data and spans over 10 years that were classified into three categories, namely: wet year, normal year, and dry year and the influences generated by the contrasting weather (flow and temperature changes) on the trophic state of the lake. The research findings show that the trophic state of the lake is directly influenced by the hydrological variability, namely evolving to a hypertrophic status due to concentrations of nutrients. Moreover, over the years, according to ANAR data, the water quality in the reservoir alternated. Hence, at times, the quality of the water was poor, with possible negative influences on water usage. As a consequence, we proposed that the water quality be verified monthly, and this should be done by means of a more reliable method, such as a multiparameter index or multicriteria analysis.

The Impact

Nowadays the comorbid pathology of liver cirrhosis and atrial fibrillation has been widely discussed and reported in the literature in the light of recent findings from the study of the effectiveness and safety of anticoagulants in this category of patients. The review is devoted to summarizing the existing data on the comorbid course of these diseases from the point of view of the impact of bleeding and thrombosis on the quality of life and mortality of patients and the possibility of using new methods of diagnosis and prevention of these complications. The purpose of the review is to focus the attention of physicians and researches on the relevance and prevalence of comorbid course of liver cirrhosis and atrial fibrillation, their complications, and discuss the benefits and possibilities of applying global methods of hemostasis assessment and anticoagulants in clinical practice. This article examines the main pathophysiological aspects of «rebalanced hemostasis» theory in liver coagulopathies, its effect on the onset of bleeding and thrombotic events, and considering the clinical benefit of the use of anticoagulants. The disadvantages of traditional coagulation assessment tests compared to the benefits of thromboelastometry (ROTEM) and thromboelastography (TEG), general fulfilling principles and evaluation of their indicators are discussed. Existing research findings on the safety and efficacy of warfarin and direct oral anticoagulants in patients with liver cirrhosis and atrial fibrillation compared with no treatment are highlighted.

Abstract Visitors’ perceptions of the quality of a tourism destination are fundamental for effective destination management and marketing. This paper deals with the topic of destination quality from the viewpoint of demand, i.e. from the viewpoint of a destination visitor. The results of perceiving the destination quality partial factors in the context of different behavioural characteristics of a visitor are presented, particularly, the way how spending and organizing a holiday influences the perception of destination quality factors (Kruskal-Wallis test). The research nineteen factors were designed on the basis of contemporary theories and on qualitative research. Some important quality aspects related to tourism were identified and assessed for the Czech population. The primary data were obtained through a questionnaire survey with quota sampling (n = 1097). The dependence of destination quality perception on the way of spending the holiday was revealed in the case of 8 factors (e.g., Availability of transportation to the destination, Availability and quality of information; Additional infrastructure, Sense of security, Destination cleanliness, Uniqueness of destination, Price level in the destination, Cultural monuments). The significant differences identified among various groups of respondents are described in detail in this study. The research findings contribute to better understanding of the behavioural mechanism and can be used by destination managers to design communication strategies for different segments of consumers for individual destinations to improve their competiveness.

Harare City

Harare City Council has both “processes” and “outputs” crises. The processes crisis includes waste, red tape, delay, mismanagement and corruption within the local authority. The outputs crisis involves failure to deliver what it should. Quality of service delivery is poor. E-governance contributes to poverty reduction through making communication easier and more affordable by enabling speedy and secure economic transactions. Participation is central to good governance and an important factor for sustainable development. Local authorities are closest to residents and thus in a better post to effectively drive participation. E-governance therefore means e-participation hence connecting residents of different social, academic, political and cultural backgrounds. The research explores the questions: how does e-governance improve service delivery and good governance such as responsiveness, transparency, accountability, effectiveness governance, improved participation, effectiveness and efficiency. The research findings indicate that the relationship between e-governance and participation is positive and strong. The findings are based on Harare City Council activities, analysis of key documents, views of key informant and content analysis. Recommendations proffered include the coming up with a shared e-governance strategy for Harare City Council by the Ministry of Local Government, Urban and Rural Development and Harare City Council. This must result in website creation. Residents’ awareness must be conducted through workshops, seminars and conferences in order to explain the benefits of e-governance. Human development designed to empower residents with basic ICT skills must be embarked upon.

The present paper reexamines the psychometric properties of the Quality Perception Questionnaire (QPQ), an Italian survey instrument measuring patients’ perceptions of the quality of a recent hospital admission experience, in a sample of 4400 patients (Mage = 56.42 years; SD = 19.71 years, 48.8% females). The 14-item survey measures four factors: satisfaction with medical doctors, nursing staff, auxiliary staff, and hospital structures. First, we tested two models using a confirmatory factor analysis (structural equation modeling): a four orthogonal factor and a four oblique factor model. The SEM fit indices and the χ² difference suggested the acceptance of the second model. We then did a simulation using a bootstrap with 1000 replications. Results confirmed the four oblique factor solution. Third, we tested whether there were significant differences with respect to age or sex. The multivariate general linear model showed no significant differences in the factors with respect to sex or age.

BACKGROUND: Remotely guided ultrasound (US) examinations carried out by nonmedical personnel (novices) have been shown to produce clinically useful examinations, at least in small pilot studies. Comparison of the quality of such exams to those carried out by trained medical professionals is lacking in the literature. This study compared the objective quality and clinical utility of cardiac and pulmonary US examinations carried out by novices and trained physicians.METHODS: Cardiac and pulmonary US examinations were carried out by novices under remote guidance by an US expert and independently by US trained physicians. Exams were blindly evaluated by US experts for both a task-based objective score as well as a subjective assessment of clinical utility.RESULTS: Participating in the study were 16 novices and 9 physicians. Novices took longer to complete the US exams (median 641.5 s vs. 256 s). For the objective component, novices scored higher in exams evaluating for pneumothorax (100% vs. 87.5%). For the subjective component, novices more often obtained clinically useful exams in the assessment of cardiac regional wall motion abnormalities (56.3% vs. 11.1%). No other comparisons yielded statistically significant differences between the two groups. Both groups had generally higher scores for pulmonary examinations compared to cardiac. There was variability in the quality of exams carried out by novices depending on their expert guide.CONCLUSION: Remotely guided novices are able to carry out cardiac and pulmonary US examinations with similar, if not better, technical proficiency and clinical utility as US trained physicians, though they take longer to do so.Dufurrena Q, Ullah KI, Taub E, Leszczuk C, Ahmad S.

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

Physical Capital Accumulation

This paper discusses the relation between the quality and quantity indicators of physical capital and modernisation. While international academic literature emphasises the role of intangible factors enabling technology generation and absorption rather than that of physical capital accumulation, this paper argues that the quantity and quality of physical capital are important modernisation factors, particularly in the case of small, undercapitalised countries that recently integrated into the world economy. The paper shows that in Hungary, as opposed to developed countries, the technological upgrading of capital assets was not necessarily accompanied by the upgrading of human capital i.e. the thesis of capital skill complementarity did not apply to the first decade of transformation and capital accumulation in Hungary. Finally, the paper shows that there are large differences between the average technological levels of individual industries. The dualism of the Hungarian economy, which is also manifest in terms of differences in the size of individual industries' technological gaps, is a disadvantage from the point of view of competitiveness. The increasing differences in the size of the technological gaps can be explained not only with industry-specific factors, but also with the weakness of technology and regional development policies, as well as with institutional deficiencies.
