Purpose By drawing on the institutional theory and contingency theory, this study aims to examine the effects of leadership and accounting capacity on the quality of financial reporting and accountability of public organisations in Vietnam. Furthermore, this paper is to determine the impact of financial reporting quality on accountability. Design/methodology/approach The research model and hypotheses have been tested by partial least squares structural equation modeling, with 177 survey samples obtained from accountants and managers working in the public sector in Vietnam. Findings The research results indicate that leadership and accounting capacity have a positive effect on financial reporting quality; leadership and accounting capacity positively influence accountability; and the quality of financial reporting has a positive impact on accountability. Research limitations/implications The research results provide empirical evidence of the direct impact of leadership and accounting capacity on financial reporting quality and accountability of public organisations in a developing country. Moreover, the current work also provides important evidence for the impact of financial reporting quality on accountability. Practical implications Public sector organisations must realise that leadership and accounting capacity play a vital role in the accounting reform process. Public institutions likewise need to pay attention to develop accounting capacity and promote leadership. Moreover, the results respond to the continuing call for increased citizen trust in public organisations. Originality/value To the best of the authors’ knowledge, this study is the first to examine the chain from leadership, accounting capacity, financial reporting quality and accountability in the context of public sector organisations in an Asian transition market.

This paper describes the selected demographic characteristics as moderators of the impact of the quality of interpersonal relationships at work on counterproductive work behaviours. The main purposes of the research are describing: 1) how interpersonal relationships at work influences the intensity of counterproductive work behaviours; 2) how sex, age, education, length of service and type of job moderate the influence of interpersonal relationships at work on counterproductive work behaviours; 3) how the above-mentioned demographic characteristics influence interpersonal relationships at work and counterproductive work behaviours separately. The studies on the literature indicated that there were no comprehensive research results concerning those problems. The research paper fills a gap in the literature relating to the impact of interpersonal relationships at work on counterproductive work behaviours and the relation to modelling this impact by demographic characteristics of employees (sex, age, education, length of service, type of job). To achieve the study purposes, the author conducted a survey conducted on a sample of 1336 active employees in Poland. The survey period was 2018-2019. The IBM SPSS Statistics and IBM SPSS Amos were used to analyze data. Based on Structural Equation Modelling, it was that:1) interpersonal relationships at work negatively impacted on the intensity of counterproductive work behaviours against another individual; 2) the strength of influence of interpersonal relationships at work on counterproductive work behaviours did not change relevantly in modelling with selected demographic characteristics (sex, age, education, length of service, type of job); 3) only education, current kind of job and service length had a relevant influence on interpersonal relationships at work and counterproductive work behaviours. The research results could be useful for managers. In their activities, managers should systematically monitor interpersonal relationships at work and counterproductive work behaviours taking into account employees' demographic characteristics. In this process, managers should pay particular attention to education, type of current job, and service length.

Linking a publication with scientific research results and the use of information resources is a key component of the collection, development and assessment of an academic library. Librarians often use quantitative data, but it is not easy to come by. Directly connecting library and information services to the impact they have can be quite difficult. Focusing on the 2010–2014 period, we have linked the quality and quantity of published papers to usage statistics for the newly acquired consortia access to scholarly journals in three international publisher databases: ScienceDirect, SpringerLink and WileyOnline. We found that the share of scholarly journals from the ScienceDirect, SpringerLink and WileyOnline consortia cited by University of Primorska researchers’ in their scholarly papers has gradually increased every year, ranging from 13.5% in 2010 up to 24.8% in 2014. The share of scholarly papers published by University of Primorska researchers’ in scholarly journals with the highest impact (measured in Web of Science and Scopus) has also increased substantially, from 18.03% in 2011 to 31.55% in 2014. Study shows that better access to quality information resources for scientific researchers lead to an increase in its use and results in higher quality research shown by the gradual increase of publications of research results in higher impact scholarly journals.

Thai Binh is a coastal province of Red River Delta in Vietnam, having administrative boundaries at the river systems and coastlines that cause groundwater quality varies complicatedly. Today in Thai Binh province, the groundwater in Holocene and Pleistocene aquifers is exploited for domestic use. But, beside the quality of groundwater in this region is not uniform, it is interspersed between salt water and fresh water zones in Holocene and Pleistocene aquifers. Nowaday, under the force of groundwater exploitation activity for domestic purposes, agricultural activities, the impact of climate change and sea level rise issues, the quality of distribution of groundwater here change. According to the recent research results, groundwater quality and distribution of salt water - fresh water there have many changes compared with the research results of the Northern Division for Water resources Planning and Investigation in the year 1996. For the the Holocene aquifer (qh), distribution area of salt water zone has been narrowed. Besides, saline cleaning process occurred in some coastal areas in Tien Hai, Thai Thuy and a part of Quynh Phu district. For the Pleistocene aquifer (qp), compared with research result in 1996, the boundaries between saline and fresh water at the present time is not change so much. By assessing the status of the distribution of saline and fresh water zones in groundwater in Thai Binh and the movement of this boundary, author’s research results will be the basis that helps the managers give out reasonable exploiting and sustainable using methods for these natural resources. Thái Bình là một tỉnh ven biển thuộc vùng châu thổ sông Hồng của Việt Nam, được bao bọc bởi hệ thống sông biển khép kín làm cho chất lượng nước ngầm biến đổi rất phức tạp. Hiện nay, tại Thái Bình có 2 tầng chứa nước chính phục vụ ăn uống sinh hoạt là tầng chứa nước Holocen và tầng chứa nước Pleistocen. Tuy nhiên, chất lượng nước ngầm ở các tầng chứa nước này không đồng đều, có sự phân bố xen kẽ giữa các khoảnh nước mặn và nước nhạt. Hiện nay, dưới tác động của hoạt động dân sinh, sản xuất nông nghiệp, khai thác nước phục vụ sinh hoạt cùng ảnh hưởng của biến đổi khí hậu và sự dâng cao của mực nước biển đã làm thay đổi chất lượng và quy mô phân bố nước ngầm khu vực. Theo những kết quả nghiên cứu mới nhất của tác giả cho thấy diện tích phân bố của các vùng nước mặn - nước nhạt của các tầng chứa nước trên địa bàn tỉnh đã có nhiều thay đổi so với kết quả nghiên cứu trước đây của Liên đoàn Địa chất thủy văn – Địa chất công trình miền Bắc năm 1996. Với tầng chứa nước Holocen, diện tích phân bố các khoảnh nước mặn bị co hẹp và đang có sự nhạt hóa tại một số khu vực ven biển thuộc Huyện Tiền Hải, Thái Thụy và một phần thuộc huyện Quỳnh Phụ. Trong tầng chứa nước Pleistocen (qp), so với kết quả nghiên cứu năm 1996, ranh giới mặn – nhạt tại thời điểm hiện tại đã có sự thay đổi nhưng không lớn. Kết quả nghiên cứu này là cơ sở giúp các nhà quản lý đề xuất giải pháp, phân vùng khai thác và sử dụng hợp lý nguồn tài nguyên thiên nhiên này đặc biệt trước tình trạng khan hiếm nước như hiện nay trên địa bàn tỉnh Thái Bình.

This article presents the methodology and results of a pilot study concerning the impact of three popular and widely accessible machine translation engines (developed by Google, Microsoft and DeepL companies) on the pace of post-editing work and on the general effort related to post-editing of raw MT outputs. Fourteen volunteers were asked to translate and post-edit two source texts of similar characters and levels of complexity. The results of their work were collected and compared to develop a set of quantitative and qualitative data, which was later used to make assumptions related to the general rate of postediting work and the quality of the post-edited sentences produced by the subjects. The aim of the pilot study described below was to determine whether the applied method can be successfully used in more profound studies on the quality and impact of machine translation in the English->Polish language pair and on the potential of MT solutions on the Polish translation market.

For modern information systems for modeling and monitoring the labor resources, as well as to ensure the quality of a special assessment of working conditions, it is necessary to study the impact of the labor intensity and adapt methods for analyzing the non-production losses from temporary disability of employees. The authors supplemented the previously presented mathematical model for non-productive losses of working time from diseases and industrial injuries of workers engaged in dangerous and harmful working conditions with normal and increased intensity. Also, the shortcomings of the automated modeling system based on the flow model, which led to distortion of the research results, were eliminated. The influence of the labor intensity in harmful production conditions on human health is taken into account. The developers conducted experiments with the data of the automated information management system of a construction enterprise, where employees are engaged in the construction of main gas pipelines in various regions of Russia. The practical significance of the research results is formulated: the changes made to the system significantly improve the quality of special assessments of working conditions, regularly conducted at enterprises, as well as the quality of the labor norms setting. The application of the presented modeling system is especially relevant in the context of the coronavirus pandemic, when it is necessary to accurately determine the risk groups of workers.
