Recently developed methods in spontaneous speech analytics require the use of speaker separation based on audio data, referred to as diarization. It is applied to widespread use cases, such as meeting transcription based on recordings from distant microphones and the extraction of the target speaker’s voice profiles from noisy audio. However, speech recognition and analysis can be hindered by background and point-source noise, overlapping speech, and reverberation, which all affect diarization quality in conjunction with each other. To compensate for the impact of these factors, there are a variety of supportive speech analytics methods, such as quality assessments in terms of SNR and RT60 reverberation time metrics, overlapping speech detection, instant speaker number estimation, etc. The improvements in speaker verification methods have benefits in the area of speaker separation as well. This paper introduces several approaches aimed towards improving diarization system quality. The presented experimental results demonstrate the possibility of refining initial speaker labels from neural-based VAD data by means of fusion with labels from quality estimation models, overlapping speech detectors, and speaker number estimation models, which contain CNN and LSTM modules. Such fusing approaches allow us to significantly decrease DER values compared to standalone VAD methods. Cases of ideal VAD labeling are utilized to show the positive impact of ResNet-101 neural networks on diarization quality in comparison with basic x-vectors and ECAPA-TDNN architectures trained on 8 kHz data. Moreover, this paper highlights the advantage of spectral clustering over other clustering methods applied to diarization. The overall quality of diarization is improved at all stages of the pipeline, and the combination of various speech analytics methods makes a significant contribution to the improvement of diarization quality.

The present era sees an increasing trend of online purchasing all over the globe, and India is no more an exception. India is likely to become the hub for online market because it is second in terms of population in the world. The study is an effort to understand whether system quality really matters for customer satisfaction, particularly in developing countries, and the website quality works as a mediator or not. The study proposes the theoretical framework of the impact of system quality on customer satisfaction after a rigor literature review. With the help of purposive sampling, data were collected and model tested using partial least square structural equation modeling (PLS-SEM). The results show that system quality and website quality have a direct and positive impact on customer satisfaction and website quality partially mediated. Based on these empirical findings, managerial implications, limitations, and recommendations for further future research are given in the study.

PurposeThis study aims to investigate how e-health system characteristics (information quality, system quality, perceived ease of use, perceived usefulness) contribute to the enhancement of medical staff performance, patient care, and doctor–patient relationships at UNRWA-Gaza healthcare centers. It aims at testing an integrative single model comprising Technology Acceptance Model (TAM), D&M model and e-health system utilization.Design/methodology/approachThis study followed the quantitative methodology and the deductive research approach. Data were collected from 241 medical staff who use the system employed in 19 different healthcare centers across the Gaza Strip. Partial least square/structural equation modeling technique was used to analyze the collected data and to test study hypotheses.FindingsStudy concluded that information quality of the adopted Health Information System (HIS) has both direct and indirect positive impact on staff performance, only direct positive impact on patient care and only positive indirect impact on doctor–patient relationship. System quality, on the other hand, was found to have negative direct impact and positive indirect impact on staff performance and has both direct and indirect positive impact on both doctor-patient relationship and patient care.Research limitations/implicationsNoteworthy that HIS has availability, speed and error detection and error prevention issues. It is recommended that these shortfalls be addressed together with improving user perception towards ease of use and usefulness of the system.Practical implicationsManagement should also work to raise confidence in its medical staff to improve the effect of HIS on medical performance and patient care. It is also recommended that UNRWA should implement crowed management techniques such as queuing systems and on-phone booking to minimize patient waiting time.Originality/valueThe importance of the study stems from its context being conducted in a developing region (Gaza Strip-Palestine) which has a fragile economic, political and social environment with many other complexities. It is also conducted at United Nations Relief and Work Agency (UNRWA) healthcare centers, which provide medical services to Palestinian refugees. In addition, this study is among the few studies that address the impact of individual e-health success factors on both doctor-patient relationship and patient care constructs. Most previous studies concentrated on the impact of health system adoption as a whole on these two subject variables and one can hardly ever stop at studies that address effect of individual success factors on them. It also integrated both D&M system success model and TAM model with some additional amendments creating and tested a new model.

Abstract. Background: Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties. Methods: This is a retrospective cross-sectional study design. 20,748 invasive, percutaneous PVI of PAD conducted in the metropolitan area of Hamburg (Germany) were consecutively collected between January 2004 and December 2014. Results: MTD prior to PVI was associated with lower odds of early unsuccessful termination of the procedures (Odds Ratio 0.662, p < 0.001). The proportion of MTD decreased over the study period (30.9 % until 2009 vs. 16.6 % from 2010, p < 0.001) while rates of critical limb-threatening ischemia (34.5 % vs. 42.1 %), patients´ age (70 vs. 72 years), PVI below-the-knee (BTK) (13.2 % vs. 22.4 %), and rates of severe TASC C/D lesions BTK (43.2 % vs. 54.2 %) increased (all p < 0.001). Utilization of MTD was different between medical specialties with lowest frequency in procedures performed by internists when compared to other medical specialties (7.1 % vs. 25.7 %, p < 0.001). Conclusions: MTD prior to PVI is associated with technical success of the procedure. Nonetheless, rates of MTD prior to PVI are decreasing during the study period. Future studies should address the impact of multidisciplinary vascular teams on long-term outcomes.

The Impact

Based on cross-country panel regressions, the paper analyzes the impact of external currency exposures on monetary policy, exchange rate regime and capital controls. It is determined that positive net external position (which, e.g., is the case for Russia) is associated with a higher degree of monetary policy autonomy, i.e. the national key interest rate is less responsive to Fed/ECB policy and exchange rate fluctuations. Therefore, the risks of cross-country synchronization of financial cycles are reduced, while central banks are able to place a larger emphasis on their price stability mandates. Significant positive impact of net external currency exposure on exchange rate flexibility and financial account liberalization is only found in the context of static models. This is probably due to the two-way links between incentives for external assets/liabilities accumulation and these macroeconomic policy tools.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.

Zakat is one of the five pillars of Islam which has a function of faith, social and economic functions. Muslims who can pay zakat are required to give at least 2.5 per cent of their wealth. The problem of poverty prevalent in disadvantaged regions because of the difficulty of access to information and communication led to a gap that is so high in wealth and resources. The instrument of zakat provides a paradigm in the achievement of equitable wealth distribution and healthy circulation. Zakat potentially offers a better life and improves the quality of human being. There is a human quality improvement not only in economic terms but also in spiritual terms such as improving religiousity. This study aims to examine the role of zakat to alleviate humanitarian issues in disadvantaged regions such as Sijunjung, one of zakat beneficiaries and impoverished areas in Indonesia. The researcher attempted a Cibest method to capture the impact of zakat beneficiaries before and after becoming a member of Zakat Community Development (ZCD) Program in material and spiritual value. The overall analysis shows that zakat has a positive impact on disadvantaged regions development and enhance the quality of life of the community. There is an improvement in the average of mustahik household incomes after becoming a member of ZCD Program. Cibest model demonstrates that material, spiritual, and absolute poverty index decreased by 10, 5, and 6 per cent. Meanwhile, the welfare index is increased by 21 per cent. These findings have significant implications for developing the quality of life in disadvantaged regions in Sijunjung. Therefore, zakat is one of the instruments to change the status of disadvantaged areas to be equivalent to other areas.

In 2001, the website of the Palace Museum was opened to the public, marking that museum’s first step into the digital era in China. Numerous studies and much research has concentrated on how to employ this new technology in order to digitize the museum and its collection. However, little attention has been paid to research regarding visitor satisfaction’s regarding museum websites in China. This research aims to fill the gap. Consequently, this conceptual model has been proposed, and the Palace Museum website was as the research objective. Empirical methodology has been applied and the online survey was created to gather data, which results in a total of 557 questionnaires being analyzed though the SPSS 20.0. The findings demonstrate that system quality, perceived usefulness, perceived usability, and the museum’s image have a positive impact on visitor satisfaction regarding their continuance intention. Furthermore, managerial implications are proposed for museum practitioners.

Gasoline come primarily from petroleum cuts, it is the preferred liquid fuel in our lives. Two gasoline samples of octane numbers 91 and 95 from Saudi Arabia petrol stations were studied. This study was achieved at three different temperatures 20oC, 30oC and 50oC representing the change in temperatures of the different seasons of the year. Both the evaporated gases of light aromatic hydrocarbons (BTEX) of gasoline samples inside the tank were subjected to analyze qualitatively and quantitatively via capillary gas chromatography. The detailed hydrocarbon composition and the octane number of the studied gasoline samples were determined using detailed hydrocarbon analyzer. The idea of research is indicating the impact of light aromatic compounds in gasoline on the toxic effect of human and environment on the one hand, and on octane number of gasoline on the other hand. Although the value of octane number will be reduced but this will have a positive impact on the environment as a way to produce clean fuel.

Subject. The article addresses the impact of religious confession on wages and the likelihood of unemployment in Russia. Objectives. The aim is to test the hypothesis that religious faith and high church attendance are accompanied by an increase in employment earnings. Methods. Using the Russian Longitudinal Monitoring Survey data, I estimate the Mincer's extended equation with variables that characterize the respondent’s religious commitment. To assess the impact of religious identity and the activity rate of attendance at religious services on the likelihood of unemployment and life satisfaction, I use probit models. Results. The estimates demonstrate that the Russian labor market rewards men with moderate and high degree of religious commitment; their wage growth reaches seventeen percent of the level of non-believers with comparable education and work experience. However, faithful Muslim women are employed in the lowest paid areas. Religious faith and regular church attendance have a positive effect on satisfaction with life (significant for Orthodox Christian women). Conclusions. Positive impact of religious capital on income and employment can be attributed to the development of business qualities that are rewarded in the labor market, the mutual support of religious network participants. Therefore, it possible to consider religious capital, along with educational capital and health capital, as a component of human capital and a factor of socio-economic development.

One of the main criteria for economic development is the size of the public debt and its dynamics. The article considers the impact of public debt on the financial security of Ukraine. The views of scientists on the essence of public debt and financial security of the state are substantiated. An analysis of the dynamics and structure of public debt of Ukraine for 2014-2019. It is proved that one of the main criteria for economic development is the size of public debt and its dynamics. State budget deficit, attracting and using loans to cover it have led to the formation and significant growth of public debt in Ukraine. The volume of public debt indicates an increase in the debt security of the state, which is a component of financial security. Therefore, the issue of the impact of public debt on the financial security of Ukraine is becoming increasingly relevant. The constant growth and large amounts of debt make it necessary to study it, which will have a positive impact on economic processes that will ensure the stability of the financial system and enhance its security.
