An effective and elastic blockchain-based provenance preserving solution for the open data
Authors: Dang Tran Khanh , Duong Thu Anh 
Published: June 2021

Purpose
In the open data context, the shared data could come through many transformation processes, originating from many sources, which exposes the risk of non-authentic data. Moreover, each data set has different properties, shared under various licenses, which means the updated data could change its characteristics and related policies. This paper aims to introduce an effective and elastic solution to keep track of data changes and manage their characteristics within the open data platform. These changes have to be immutable to avoid violated modification and could be used as the certified provenance to improve the quality of data.

Design/methodology/approach
This paper will propose a pragmatic solution that focuses on the combination of comprehensive knowledge archive network – the broadest used open data platform and hyperledger fabric blockchain to ensure all the changes are immutable and transparent. As using smart contracts plus a standard provenance data format, all processes are running automatically and could be extended to integrate with other provenance systems and so the introduced solution is quite flexible to be used in different open data ecosystems and real-world application domains.

Findings
The research involves some related studies about the provenance system. This study finds out that most of the studies are focused on the commercial sector or applicable to a specific domain and not relevant for the open-data section. To show that the proposed solution is a logical and feasible direction, this paper conducts an experimental sample to validate the result. The testing model is running successfully with an elastic system architect and promising overall performance.

Originality/value
Open data is the future of many businesses but still does not receive enough attention from the research community. The paper contributes a novel approach to protect the provenance of open data.
Employees' preference for the on-site childcare service: a case study of three Sri Lankan apparel firms
Authors: Balasooriya B.M.A.M. , Pallegedara Asankha 
Published: June 2021

PurposeChildcare is one of the main obstacles for women to enter the labour market as they are the primary caregivers for children. The struggle between childcare and women's employment has caused a high labour turnover in women-dominated industries. The aim of this study is to assess the employees’ willingness for an on-site childcare facilityDesign/methodology/approachThe primary goal of this study was to assess the employees' willingness for an on-site childcare facility using the contingent valuation method. For the analysis, 330 data were collected from all levels of the employees in three firms in the apparel industry using a survey-based questionnaire.FindingsThe results illustrate that the mean willingness to pay for the on-site childcare facility is substantially higher for the firm that already provide an on-site childcare facility than the other two firms that do not have childcare facilities. Among all employees who are surveyed, 86.36% of the employees favoured implementation of on-site childcare facilities. According to the survey findings, the newly hired employees have a higher preference for the childcare facility, however less likely to pay for the facility. The monthly income variable has a negative association with the probability of voting in favour of implementing on-site childcare facility. Moreover, the results indicate that the employees who have received the childcare facility have positive attitudes towards the on-site childcare facility.Originality/valueTo the authors' knowledge, prior case studies related to the evaluation of employee's preference for on-site childcare services have not been conducted in the context of industries in Sri Lanka. Therefore, the findings and implications were discussed while expanding the geographical scope of the past literature.
The impact of IFRS on earnings management: evidence from Mexico
Authors: Eiler Lisa A. , Miranda-Lopez Jose , Tama-Sweet Isho 
Published: June 2021

PurposePrior literature investigating the adoption of International Financial Reporting Standards (IFRS) finds that managerial incentives, capital market institutions and accounting standards interact to endogenously determine accounting outcomes. In this paper, we investigate the impact of changing from local GAAP to IFRS in 2012 on earnings management by public firms in Mexico. Given the institutional environment and managerial incentives in Mexico, there is not a clear theoretical prediction for the impact of Mexico's adoption of IFRS on earnings management. Thus, it is an empirical question whether a change in accounting standards had any effect on earnings management.Design/methodology/approachWe use three measures of earnings smoothing and one measure of upwards earnings management. Logistic regression analysis along witht-tests across two time periods, pre-IFRS (2009–2011) and post-IFRS (2013–2015) are used to determine if there is a significant change in the earnings management of Mexican firms, and if this change is different for companies cross-listed in the US and companies listed only in theBolsa.FindingsWe hypothesize and find that adopting IFRS is associated with lower earnings management via earnings smoothing in Mexico, and the reduction is greater for firms cross-listed in the United States. Our results support the contention that strong institutions and enforcement aid in the implementation of new accounting standards.Originality/valueFirst, we contribute to the literature on the adoption of IFRS around the world. The consensus in the literature is that the impact of IFRS on financial reporting is country-specific. To our knowledge, we are the first to conduct such research on Mexico. Second, our findings indicate that IFRS adoption is associated with a reduction in earnings management through income smoothing by firms in Mexico. This contributes to a small but growing body of literature documenting consequences of improvements in Mexican capital markets. Results of research in this area provide important insights to capital market participants and regulators in Mexico.

Published: June 2021

PurposeThe paper aims to analyze the coverage of health insurance and its correlates in the north-eastern region of India.Design/methodology/approachThe study accessed the raw data of the National Family Health Survey (NFHS-4) (2015–16), which was an extensive, multiround survey conducted in a representative sample of households throughout India, which included socioeconomic, demographic and information on coverage of health insurance of any member of the household. The multivariate analysis of logistic regression was adopted to find the correlates of health insurance for all the eight (8) north-eastern states of India.FindingsThe results observed that among the north-eastern states, the coverage of health insurance was highest in Arunachal Pradesh (59%) followed by Tripura (58%), Mizoram (47%) surpassing the all India level of 27%, whereas the lowest was in Manipur (4%) followed by Nagaland (6%) and Assam (10%). The multivariate analysis of logistic regression found that the socioeconomic and demographic factors, households with a bank account and below poverty line (BPL) cardholders played a significant role in the coverage of health insurance in the north-eastern states of India.Research limitations/implicationsThe study focuses only on the coverage and correlates of health insurance. Further evaluation studies on each scheme of the social health insurance are needed for proper assessment of the health insurance schemes in the region.Practical implicationsThere has been evidence around the world (South Korea, Taiwan and Thailand) that health insurance could be a protective shield from the entrapment into poverty due to high health expenditure. The NFHS-4 put up the finding that in the north-eastern part of India, the coverage of health insurance had been low. This implied that the region could fall into poverty due to high medical expenses on health. Taking account of multiple health insurance providers, risk pooling and consolidation of health insurance providers have become the need of the hour.Originality/valueThe study is different from other studies of health insurance since it covered all the eight (8) north-eastern states of India, which are ethnically, culturally and historically distinct from the rest of India in general and within the region and states in particular and examines the impact of each of the independent variables with the dependent variables. The study has shown that the variation in health insurance coverage associated with socioeconomic and other household-level demographic attributes (although not very strong).

Authors: Tultrairatana Supakorn , Phansuea Phenphop 
Published: June 2021

PurposeThe purpose of this article was to investigate the relationship between symptoms related to air pollution, mask-wearing, mask choices and related factors.Design/methodology/approachA cross-sectional study among outpatient department (OPD) pollution clinic patients at Nopparat Rajathanee Hospital (PCNRH) during 2019 in Bangkok, Thailand.FindingsThe most common symptom after exposure to air pollution that affects treatment in the OPD is respiratory symptoms. A total of 45.7% (107/234) of the population wears a mask, 55.1% (59/107) of the population that wears a mask wears a surgical mask, and only 10.3% (11/107) of them wear an N95 mask. Mask-wearing and air quality index (AQI) onset were associated with the respiratory symptoms group, whereas wearing an N95 mask or surgical mask was found to be a protective factor for the occurrence of respiratory symptoms (adjusted OR = 0.065, 95% CI: 0.014–0.306, p = 0.001 and adjusted OR = 0.154, 95% CI: 0.058–0.404, p < 0.001, respectively). Therefore, the best practice in the face of air pollution, while the resolution needs a long period, is to wear a mask. In this study, the results showed that the best type of mask to prevent respiratory symptoms from air pollution is the N95, followed by the surgical mask; cloth masks are not recommended to use to protect against respiratory symptoms from air pollution.Research limitations/implicationsWearing an N95 and a surgical mask can help reduce respiratory symptoms. Hence, in addition to establishing hospital measures, cooperation from local and government agencies is necessary to effectively and jointly build a national health public policy framework.Originality/value1. This study provides evidence of a correlation between symptoms associated with air pollution and related factors, in-hospital visits in Bangkok, Thailand. 2. In this study, wearing an N95 mask and a surgical mask were found to be a protective factor for the occurrence of respiratory symptoms.

Authors: Grandage Andrew J. 
Published: June 2021

PurposeEffective project management is critical for reducing project failures, cost overruns and schedule delays. Yet, research in this area is lacking. This study provides original research on capital project management in US state governments, with special attention to earned value management (EVM). EVM is a technique used to provide early warning indicators of performance issues and facilitate corrective action during project execution.Design/methodology/approachA multi-method design involving document review, focus groups, surveys, interviews and case studies is used to unearth primary data from statewide project management offices (PMO) responsible for overseeing large-scale information technology (IT) acquisitions. A strategic framework is developed, facilitating a descriptive analysis of management strategies.FindingsResults from 31 states indicate the vast majority have taken key initial steps in formulating a statewide strategy, such as establishing a PMO, adopting industry standards and defining guidelines for agencies. However, agencies are only required to follow guidelines issued by the statewide PMO in 14 states. EVM is currently used in 18 states, with most defining clear criteria for application and tailoring practices according to project context.Originality/valueThis study introduces the EVM concept to public budgeting research, provides a blueprint for EVM policy development and offers novel analysis of capital project management reforms and strategies.

Risk and protective factors for post-traumatic stress among New Zealand police personnel: a cross sectional study
Authors: den Heyer Garth 
Published: June 2021

PurposeThe purpose of this research was to examine which factors increase the risk of post-traumatic stress in police officers to assist with identifying strategies that will minimize its occurrence.Design/methodology/approachThis study of constabulary and non-constabulary members of the New Zealand Police has been based on an 80-question electronic survey, which was sent to all serving, resigned and retired members of the New Zealand Police Association, which number approximately 18,000. The survey included a series of questions that measured the post-traumatic stress that participants experienced.FindingsVariables associated with post-traumatic stress were examined using logistic regression modeling techniques. The study found that post-traumatic stress was prevalent among serving, resigned and retired police members and exposure to trauma, especially prolonged exposure, was significantly associated with post-traumatic stress. More than 49% of participants were found to have some post-traumatic stress symptoms and more than 14% of participants indicated a presumptive clinical diagnosis of post-traumatic stress.Research limitations/implicationsThe limitations of the research included not include questions relating to the Social Provisions Scale (SPS) and General Health Questionnaire, nor did it include police officer recruits. A further limitation was that it was a cross-sectional study.Originality/valueAn understanding as to which variables influence or increase post-traumatic stress disorder is important for police officers and the police institution. The findings from this study indicate that exposure to trauma is strongly associated with high levels of post-traumatic stress, while good sleep and relaxation decrease the influence of such variables.

PurposeThis study has aimed to analyze the relationship between the adoption of sustainable innovation practices and the degree of innovation of business models in Brazilian industrial companies.Design/methodology/approachThe study has been characterized as quantitative and comprised the conduction of a survey with Brazilian industrial companies.FindingsResults have shown that companies with a high degree of innovation in their business models invest more strongly in strategic dimensions of sustainable innovation, which in general involve stakeholders and cross the organization's internal boundaries, requiring proactive attitudes from the company, probably because this type of investment gives them greater competitiveness in their market and also requires a radical modification of their business model.Practical implicationsThis study seeks to present contributions to entrepreneurs and policy makers, in the face of the innovative and sustainable challenges imposed by society and the guidelines for sustainable development in order to reflect on positive impacts on local and global development.Social implicationsComprehending the behavior of industrial companies in Brazil in relation to sustainable innovation and its impact on society contributes to understanding the benefits of adopting a strategic management of sustainable innovation, minimizing negative socio-environmental impacts.Originality/valueBy analyzing the themes of sustainable innovation and business model, the present study may contribute to adopting business behavior that strategically and systemically integrates the objectives of sustainable innovation.
Impedance loading an acoustic source in a borehole located in a fluid‐saturated porous medium

Published: June 2021

ABSTRACTConventional sonic logging tools are destined mainly for the determination of elastic waves’ velocities. In this paper, we have considered a different type of sonic logging tool that is destined for the registration of parameters of reflected waves in a borehole. We have calculated the mechanical impedance loading an acoustic source located on the axis of a fluid‐filled borehole. The problem was solved for a borehole drilled in a poroelastic formation. The solution was obtained in the framework of the Biot theory of poroelasticity. We have considered two limiting cases with permeable and impermeable (mudcake at the boundary between the borehole and porous rock) borehole wall. We have obtained the frequency dependences of the mechanical impedance. It was shown that the acoustic system ‘logging tool – fluid‐filled borehole – porous rock’ presents several resonance frequencies. These resonances’ frequencies are close to the resonance frequencies of a liquid layer between two rigid cylinders with radii equal to the source and borehole radii. The mechanical impedance calculated at the resonance frequency depends on the porosity and permeability that allows one to use impedance measurements in the frequency range near the resonance to determine the filtration properties of highly permeable rocks (of order higher than 10 mD). We have calculated the mechanical impedance in the low‐frequency range. The results obtained have shown that the use of low‐frequency impedance measurements provides a good way to evaluate the permeability of porous media.
