In order to better control rumor, it is necessary to clarify its micro dissemination mechanism. The paper relies on the MOA theoretical framework to clarify the motivational factors, opportunity factors, and ability factors of the spread of health rumors among the elderly people, and uses interview methods to study the micro dissemination mechanism of health rumors. Research has found that the spread of health rumors among elderly people mainly follows the path of “getting health rumors ? health rumors diffusing within peer groups ? health rumors overflowing from the circle of elderly people ? family members contained”, and forms a “Four Point Dissemination” mechanism that connects peer groups and primary groups, including origin, nodes, fulcrums, and endpoints. From the perspective of communication characteristics, the spread of health rumors has a strong closeness, inter-generational, and situational nature, presenting a double-layer communication structure that intersects within the circle and connects outside the circle, and has a prominent Pareto effect.","PeriodicalId":33161,"journal":{"name":"AJAR Asian Journal of Accounting Research","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85179681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research results show that in the 2016-2020 period, labor productivity of the whole economy has improved markedly, with an average increase of 5.78%/year in the 2016-2020 period. However, Vietnam’s labor productivity still has internal limitations that have not been overcome. In comparison with selected Asian countries, Vietnam’s labor productivity has a low absolute value despite its relatively high growth since 1991. In most of the sectors compared, it is basically at the lowest level. As a result, proposing solutions to improve and enhance labor productivity aimed at promoting sustainable economic growth in Vietnam in the coming time is an urgent issue for the development of the country.","PeriodicalId":33161,"journal":{"name":"AJAR Asian Journal of Accounting Research","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88133940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors offer practical implications for practitioners and policymakers, such as improving the corporate governance system and promoting better investment opportunities by establishing a transparent and competitive environment.Originality/valueOur study differs from other studies due to different corporate governance and political connection settings. While most prior studies examine the investment behavior of politically connected firms using the Chinese context, the authors use Indonesia which has different political and governance landscapes.

The purpose of this paper is to extend the prior literature on the effect of gender heterogeneity on environmental, social and economic performance dimensions, specifically, whether the female boardroom presence weakens or strengthens the performance along the three dimensions, commonly referred to as the corporate sustainability.Design/methodology/approachThe study from a positivist philosophy adopts a quantitative approach, and the final sample consisted of forty-six companies listed on the Nigerian Stock Exchange for the year 2011–2018. The final sample was a balanced panel of 344 firm years. The dependent variables were return on assets (ROA), environmental performance (ENV) and donations made for social causes (SOP). The ENV was measured using a content scoring system, with range of 1 to 5. The data were analysed using the fixed effects and GLM regression models. To further address the issue of endogeneity, a two-stage least squares regression was conducted.FindingsThe findings show a positive relationship between gender heterogeneity and ROA, which was also confirmed for the environmental performance index. However, the sign reversed in the SOP model and showed a negative relationship between gender heterogeneity and donations, the proxy for SOP. The results are in tandem with the stakeholder axioms that argue that commitment to other stakeholder groups strengthens firm performance in the long run.Research limitations/implicationsAn implication of this study is the fact that information availability has been rapidly escalating in the country, leading to rising social movements and civic unrest; therefore, corporations that face negative castigations may pay the huge price of product boycott and loss of market value.Originality/valueThe findings of this study provide additional insight into the influence of female boardroom presence on the environmental, social and economic performance of firms. The findings suggest the relevance of the resource dependence theory, especially from a developing country context, to ensure an improved corporate governance structure in Nigerian manufacturing firms.","PeriodicalId":33161,"journal":{"name":"AJAR Asian Journal of Accounting Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49322878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With panel data, the authors employ the multiple regression approach and the generalized least squares (GLS) estimate method. The sample is made up of 41 listed companies observed from the first half of 2016 to the second half of 2020.FindingsThis study finds that, during the pandemic period, Tunisian firms use decreasing income discretionary accruals. Also, with regard to REM, the COVID-19 variable displays a negative response coefficient but of lesser magnitude.Research limitations/implicationsThis study's findings can help Tunisian authorities, listed companies and market investors to better understand EM practices during a negative shock and to better understand the various internal and external factors influencing the quality of financial reporting. These findings may contribute, also, significant EM implications for scholars interested in other emerging markets. As limitations, the authors point out mainly to the small sample size used in this study and that the authors used a single model, namely the modified Jones model (1995), to measure the accounting EM. Also, the authors used a binary variable as a proxy for the COVID- 19 pandemic.Originality/valueTo the best of authors’ knowledge, it is the first in Tunisia, if not in Africa, to examine the impact of the COVID-19 pandemic on EM practices. Second, this study builds on previous work by examining both the accrual-based EM and the REM.","PeriodicalId":33161,"journal":{"name":"AJAR Asian Journal of Accounting Research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42277033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about differences in filial piety between rural and nonrural regions of China and Taiwan, as well as gender differences in filial piety. Using data from the 2006 East Asia Social Survey, results indicated that there were no differences in attitudes about filial piety and attitudes of financial support between rural and nonrural regions in China and Taiwan, as well between adult men and women. Caregiving for elderly parents was more common in rural China, compared to nonrural China, and men in rural China were more likely to be engaged than rural women in caregiving. There were no other differences in reports of caregiving.
