The purpose of this article is to determine necessary and sufficient conditions in order that (D, K) to be an S-accr pair, where D is an integral domain and K is a field which contains D as a subring and S is a multiplicatively closed subset of D.

The methods used are from the topic multiplicative ideal theory from commutative ring theory.

Let S be a strongly multiplicatively closed subset of an integral domain D such that the ring of fractions of D with respect to S is not a field. Then it is shown that (D, K) is an S-accr pair if and only if K is algebraic over D and the integral closure of the ring of fractions of D with respect to S in K is a one-dimensional Prüfer domain. Let D, S, K be as above. If each intermediate domain between D and K satisfies S-strong accr*, then it is shown that K is algebraic over D and the integral closure of the ring of fractions of D with respect to S is a Dedekind domain; the separable degree of K over F is finite and K has finite exponent over F, where F is the quotient field of D.

Motivated by the work of some researchers on S-accr, the concept of S-strong accr* is introduced and we determine some necessary conditions in order that (D, K) to be an S-strong accr* pair. This study helps us to understand the behaviour of the rings between D and K.

This paper aims to investigate the joint effect of product market competition (PMC) and institutional environment on accrual quality.

The sample covers a large data set of 52,138 firm-year observations from 35 countries over the period of 2011-2015. Using the weighted least square regression, the study estimates PMC and institutional environment on accrual quality. The study measures PMC based on Herfindahl-Hirschman index, anti-director rights index (ADRI) based on the revised and updated La Porta et al.'s (1998) and accrual quality using the modified Dechow and Dichev (2002) model proposed by McNichols (2002). The study also uses a series of specification tests using alternative measures for each variable.

The study finds that highly intensified PMC relates to a lower quality of accruals. The results also show that accrual quality is better in countries with stronger institutional environment, specifically countries with higher ADRI, investor protection, judicial independence, protection of minority shareholders’ interests, protection of property rights, strength of the auditing and reporting standards, efficacy of corporate boards and corporate ethics. The findings suggest that institutional factors weaken the negative impact of PMC intensity on accrual quality, hence suggesting that institutional environment has a significant role to enhance accrual quality among firms in highly intensified industries.

The findings provide additional insights to policymakers and regulators on the importance of strong institutional and industry environment that can provide incentives and extra governance mechanisms besides the conventional firm-level corporate governance.

This study contributes in understanding the impact of intensity of PMC on accrual quality internationally and subsequently highlights the role of institutional environment as significant country-level governance in determining financial reporting quality, particularly accrual quality.

This paper aims to ask whether the implementation of the expanded auditor’s report, which included a requirement to disclose key audit matters (KAMs) in Thailand since 2016, has improved audit quality.

To answer this question, the authors examined audit quality two years before and two years after its adoption by analysing 1,519 firm-year observations obtained from 312 companies. The authors applied logistic regression analyses to the firm-year observations.

The authors found some weak evidence that KAMs disclosure improved audit quality because of auditors putting more effort into their audits and audits being performed thoroughly after the implementation of KAMs. Interestingly, the number of disclosed KAMs and the most common types of disclosed KAMs are not associated with audit quality. Only disclosed KAMs related to acquisitions are more informative because the presence of this type of disclosed KAMs signals the greater likelihood of financial restatements being made in a later year.

Unlike previous studies on the impact of KAMs disclosure on audit quality, which used discretionary accruals as proxy for audit quality, this study used the occurrence of financial restatements.

We introduce a multi-level model of the dependence of interfirm network topologies on the distribution and commonality of information in a network and the information strategies pursued by its member firms. Network topology, information properties of the network, and firm-level action within the network form dynamic, recursive, cross-level relationships – information properties in the network determine firm-level action, which in turn impacts the network topology and information properties. We derive predictions about the kinds of information strategies that firms are likely to adopt and succeed with in different information regimes, and about the kinds and short- and long-run dynamics of network topologies expected under different information regimes. Our model sheds new light on network topologies as a dependent variable that can be explained by network-level information regimes and firm-level information strategies.

The purpose of this study is to assess the level and variability of Ghanaian property and liability insurer’s reserve estimates to examine its sources and ascertain if reserve errors are random or not (i.e. manipulated or not).

It uses information on insurer claim reserve provisions, claims outstanding, claims incurred and claims paid for the period of 2000-2010. Categorizing the sources of variation as endogenous and exogenous, the authors use the panel correlated standard error regression model to determine sources and magnitude of industry reserve error.

The study finds that size, age, lag of loss reserve error, inflation rate and real gross domestic product are significant in determining the degree of reserve error variation. Type of ownership (domestic or foreign) is, however, not a significant source of variation. Further, the authors found that industry reserve errors are random (not manipulated) across firms, suggesting that sampled insurers act independently on reserve error decision making and are not influenced by industry trends and competition.

The main research study limitation is the difficulty involved in obtaining annual statements from insurance companies in Ghana. Reluctance of companies to make statements available impeded on the smooth flow of the study during data collection.

Policy-wise, this suggest that regulatory bodies can uniquely set reserve error levels for existing firms with little influence on competition. Further, the Ghanaian insurance regulator does not to focus on the type of ownership (foreign or local) when setting regulatory standards. However, size of the company and age (length of operation) should be considered.

This paper is the first empirical study to examine the loss reserve error and loss reserve variability of Ghanaian property and liability insurance companies.

This study aims to examine the (overt) arguments and (covert) myths the Business Accounting Council (BAC) members have used to lobby over controversial accounting issues, such as the application of fair value accounting (FVA) and the adoption of International Financial Reporting Standards (IFRS) in Japan.

The authors used a content analysis to examine 85 statements included in multiperiod BAC meeting minutes and 68 articles prepared by International Accounting Standards Board (IASB) representatives from Japan.

The results reveal that together with the arguments, myths were created and amplified by opponents of FVA and the Financial Services Agency to hide the latter’s strong regulatory power. They created these myths, using covert stories of the importance of manufacturing activities and tax accounting (for small- and medium-sized enterprises [SMEs]), to oppose mandatory IFRS adoption in Japan and, thus, to maintain vested rights in preparing the Japanese generally accepted accounting principles and Japanese accounting standards for SMEs.

First, this study contributes to the lobbying literature by focusing on the coalition (network) effect of influential stakeholder groups. Second, although lobbying activities have been investigated mostly using comment letters, this study reviews multiperiod BAC meeting minutes and articles prepared by IASB representatives from Japan. Third, the study examines both overt arguments and covert myths, both of which are important in unmasking the fundamental structures of power within influential organizations, such as government agencies and standard-setters.

We examine how school districts in California help their high schools respond to state accountability requirements. We discovered two contrasting forms of district interventions: those aiming to increase schools’ internal coherence and those encouraging direct but narrower responses to state requirements. Drawing on interviews in six districts and eight high schools, we find that many district efforts focus on immediate responses to state requirements to raise test scores. Yet, our analysis suggests that without strong district efforts to increase internal coherence, interventions aimed at eliciting school responses will be less beneficial over time.

The racial and ethnic representation of individuals in the workforce is not comparable to that in the general population. In 2010, African Americans constituted 12.6% of the US population. However, African Americans represented less than 5% of PhD recipients in 2010; African American women comprised less than 1% of the degrees awarded in that same year. These disappointing statistics have sparked conversations regarding the retention of underrepresented groups with a focus on what helps to ensure these individuals will transition through the science, technology, engineering, and mathematics (STEM) pipeline. This chapter provides insight into the elements of the Spelman College learning environment that empower women of African descent to become agents of their success while facilitating their movement through the STEM pipeline. The chapter focuses on interventions and resources developed in the Chemistry and Biochemistry Department to foster student-centered learning. Described herein are cocurricular strategies and course-based interventions are used synergistically to enhance student outcomes. The approach to curricular innovation is framed by theories related to community of inquiry (CoI), metacognition, agency, and self-regulated learning. Strategic institutional investments have underpinned these efforts. In addition to providing a snapshot of student outcomes, the authors discuss lessons learned along with the realities of engaging in this type of intellectual work to elucidate the feasibility of adopting similar strategies at other institutions.

The following is an introductory profile of the fastest growing firms over the three-year period of the study listed by corporate reputation ranking order. The business activities in which the firms are engaged are outlined to provide background information for the reader.

The resource-based view of the firm and strategic groups research are two of the most investigated frameworks in strategic management. Historically, assumptions behind these two views have seemingly put them at odds. The resource-based view of the firm argues that sustained competitive advantage is best attained when firms have unique resources, while strategic groups research argues that a number of firms within the same industry can achieve sustained profitability with strategies that are similar to one another, but distinct from other industry members. The two views focus on different levels of analysis and each largely ignores the other’s focal level. Yet neither offers any propositions that are incompatible with the tenets of the other. Thus, conceptual integration that crosses levels of analysis is possible and potentially fruitful. Indeed, some strategic groups research has begun to bridge the gap between these two theories by suggesting that firm differences exist both within and between strategic groups. This article adopts a multi-level view by developing propositions concerning contingencies when firm differences, group processes, or both may lead to sustained competitive advantage. Implications for practitioners as well as suggestions for future theory building and empirical tests are also discussed.
