Based on the sample data of the listed firms on the A stock market, we analyze how the system of independent directors influence the earning conservatism from 4 dimensions designed to measure the monitoring power of these independent directors: Percentage within BDs, professional capacities, stimulation and work conditions. From the empirical results, we conclude that the more powerful of the independent directors, the better the accounting conservatism, and that their positive impact increases along with the improvement on corporate governance, meanwhile the work conditions plays the most important role, and then are the percentage within BDs and their professional capacities, the stimulation and personal reputation appear the least importance. 展开更多

The empirical study finds that the amount of debt affects significantly the prudence,that is,the greater the amount of the debt contract con- cluded, the stronger role of accounting conservatism is ; Debt maturity have significant relationship with accounting conservatism. For the shorter debt maturity, the enterprise is easier to choose more prudent accounting policy, and when the period is longer, accounting conservatism is relatively weaker. 展开更多

This study seeks to examine the influence of board skill, multiple directorships (BSHIP), and tenure of independent directors on accounting conservatism, as measured by asymmetric timeliness and accrual-based conservatism (CONACCR). Fixed-effect regression models were constructed on a sample of 2016 firm-year observations for asymmetric timeliness model and 2033 firm-year observations for CONACCR model, which covered from 2001 to 2007. The findings show that the degree of financial expertise on the board is positively associated with the recognition of bad news which is relative to good news into earnings. BSHIP appears to have no effect on conservatism. Independent directors who have longer tenure in the board of the firms are slower in recognizing bad news which is relative to good news into earnings. The study provides empirical evidence on the effectiveness of the board of directors, which will be an interest to the practitioner or regulators in reviewing the corporate governance regulations. 展开更多

This study aims to evaluate the level of accounting conservatism when preparing financial statements by companies listed in Kuwait Stock Exchange (KSE). In addition, the study examines the factors that affect the level of accounting conservatism in those companies with regard to company sizes, debt contracts, and the type of sector the company belongs to. To achieve these goals, the Basu (1997) model was used to measure conservatism level and the factors influencing it. The sample of the study comprises of 225 companies listed in KSE. Findings of the study showed that the KSE succeeded in forcing Kuwait companies to present a reasonable level of accounting conservatism. The study also found out that the financial statements of small companies were conservative, while those of the big ones were not. In addition, the debt contracts left an impact upon financial reports of accounting conservatism. Thus, companies with lower debts were more conservative than those of higher ones. Moreover, the financial statements of the financial sector in KSE were the most conservative. 展开更多

"Conservatism" is a widely accepted accounting convention in the industrialized world, but it has long been slated and prohibited under the orthodox ideological influences. To date, the conservatism convention has not been fully adopted or implemented although the governments have made substantial efforts to reform its accounting system to bridge the gaps between the accounting practices in recent years. The study findings will facilitate a proper assessment of the future development of accounting standards and practices. 展开更多

As one of the representative Chinese writers who was born in the 1970s,Qiao Ye's writing exhibits considerable diversity and varied understandings of literature across genres.In her full-length novels,Qiao Ye is exceptionally innovative and exploratory,and each novel is distinct in subject matter and style.However,her medium-length and short stories tend to be more conservative,characterized by a simple and natural style,imbued with the charm of literary tradition.This artistic stance in writing style is different from other writers and unique to Qiao Ye,which is not only indicative of her vivid artistic individuality but also holds value for further research into creative writing and stylistics. 展开更多

Mountains are paramount for exploring biodiversity patterns due to the mosaic of topographies and climates encompassed over short distances.Biodiversity research has traditionally focused on taxonomic diversity when investigating changes along elevational gradients,but other facets should be considered.For first time,we simultaneously assessed elevational trends in taxonomic,functional,and phylogenetic diversity of woody plants in Andean tropical montane forests and explored their underlying ecological and evolutionary causes.This investigation covered four transects(traversing ca.2200 m a.s.l.) encompassing 114 plots of 0.1 ha across a broad latitudinal range(ca.10°).Using Hill numbers to quantify abundance-based diversity among 37,869 individuals we observed a consistent decrease in taxonomic,functional,and phylogenetic diversity as elevation increased,although the decrease was less pronounced for higher Hill orders.The exception was a slight increase in phylogenetic diversity when dominant species were over-weighted.The decrease in taxonomic and functional diversity might be attributed to an environmental filtering process towards highlands,where the increasingly harsher conditions exclude species and functional strategies.Besides,the differences in steepness decrease between Hill orders suggest that rare species disproportionately contribute to functional diversity.For phylogenetic diversity the shifting elevational trend between Hill orders indicates a greater than previously considered influence in central Andean highlands of tropical lowlands originated species with strong niche conservatism relative to distantly related temperate lineages.This could be explained by a decreasing presence and abundance of temperate,extratropical taxa towards the central Andes relative to northern or southern Andes,where they are more prevalent. 展开更多

The culture wars that simmer within any nation may have been escalating recently;but regardless of their national settings or milieus,many of these wars are informed by two opposing paradigms of culture.This paper analyzes two of these leading paradigms,designated here as Regressivism and Progressivism.Other theorists have long chronicled the differing strengths and weaknesses of these paradigms,taking the former as expressing more conservative,traditional,and nationalistic values,and the latter as expressing more liberal,pluralistic,and cosmopolitan values.Going beyond these perennial distinctions,I argue that Progressivism is more benign and beneficial than the former-by meeting basic human needs better and supporting more effective adaptation to changing exigencies.I also argue that Progressivism does not express merely subjective or relativistic preferences and values,but objectively preferable and quantifiable ones,that benefit not only our personal lives more but also our global village and communal lives more. 展开更多

A principal-agent relationship exists among creditors,shareholders and management,and information asymmetry among them leads to asymmetric loss functions,which induces conservative accounting.This paper investigates the determinants of accounting conservatism using accrual-based measures and data from 2001 to 2006 in China.We find that a higher degree of leverage,lower level of control of ultimate shareholders and lower level of management ownership lead to more conservative financial reporting.We also find that political concerns and pressures among state-owned enterprises are greater than those among non-state owned enterprises,which leads to more conservative financial reporting among the former.However,a decrease in such concerns leads to a decrease in accounting conservatism.Overall,we find that among the determinants of conservatism in China,debt is the most important,followed by ownership,and that board has little influence. 展开更多

Based on signaling and gender discrimination theory, we examine whether chief financial officer(CFO) gender matters to bank–firm relationships and the designing of collateral clauses in bank loan contracting, and explore the potential path of influence. Data taken from Chinese listed companies between2009 and 2012 indicate that(1) female-CFO-led firms are less likely to obtain credit loans than male-CFO-led firms;(2) female-CFO-led borrowers are more likely to be required to provide collateral for loans than male-CFO-led borrowers; and(3) banks are more inclined to claim mortgaging collateral when lending to female-CFO-led firms and prefer to guarantee collateral when lending to male-CFO-led firms. Female-CFO-led borrowers seem to be granted more unfavorable loan terms than male-CFO-led borrowers, supporting the hypothesis that female CFOs experience credit discrimination. Further analysis reveals that regional financial development helps to alleviate lending discrimination against female CFOs. Furthermore, female CFOs in SOEs are less likely than their non-SOE counterparts to experience gender discrimination in the credit market. 展开更多

This paper investigates the factors affecting the conservatism of accounting reports at the market-level and firm-level. At the market-level, law and institutional factors explain conservatism, while at the firm-level contracting is the driver. We predict and observe that while both levels jointly affect conservatism, it is firm-level factors that play a dominant role. The conclusion suggests that it is more effective to improve the quality of accounting reports by motivating the firm's own demand rather than through listing in a developed capital market. 展开更多

Using a sample of A-share listed firms in China during the 2003–2012 period,this paper investigates the effect of accounting conservatism on trade credit,taking changes in monetary policy into account.We find that corporations with higher accounting conservatism obtain more trade credit and that accounting conservatism has a greater influence on trade credit under tight monetary policy.Furthermore,the backgrounds of the supplier and customer influence the positive relationship between accounting conservatism and trade credit.This influence is more evident when a company is privately owned and has greater market power,and less evident when the supplier or customer is the controlling shareholder. 展开更多

Species range expansions are crucial for understanding niche formation and the interaction with the environment.Here,we studied the bumblebee Bombus haematurus Kriechbaumer,1870,a species historically distributed from northern Serbia through northern Iran which has very recently started expanding northwestward into Central Europe without human-mediated dispersal(i.e.,it is a natural spread).After updating the global distribution of this species,we investigated if niche shifts took place during this range expansion between newly colonized and historical areas.In addition,we have explored which climatic factors may have favored the natural range expansion of the species.Our results indicated that Bombus haematurus has colonized large territories in 7 European countries outside the historical area in the period from the 1980s to 2018,a natural expansion over an area that equals 20%of the historical distribution.In addition,this bumblebee performs generalism in flower visitation and it occurs in different habitats,although a preference for forested areas clearly emerges.The land-use associated with the species in the colonized areas is similar to the historical distribution,indicating that no major niche shifts occurred during the spread.Furthermore,in recently colonized localities,the range expansion was associated with warming temperatures during the winter and also during both queen overwintering and emergence phases.These findings document a case of natural range expansion due to environmental change rather than due to niche shifts,and specifically they suggest that warmer winters could be linked to the process of natural colonization of new areas. 展开更多

Mergers and acquisitions(M&As)are among the most important investment activities for companies,but they contain great risks.We investigate the role of accounting conservatism in M&A target selection and risk.We find that for risk-averse reasons,firms with high accounting conservatism are likely to acquire profitable targets and avoid loss-making targets.When such firms acquire loss-making targets,the conservatism’s risk-control role reduces M&A risk and increases M&A performance,but only when control of the target is transferred and the acquirer has high long-term debt and low management power.Furthermore,accounting conservatism reduces risk by increasing the maturity match between cash flow and debt.Our results suggest that accounting conservatism plays not only a risk-averse role but also a riskcontrol role,providing new evidence for the usefulness of accounting conservatism in M&A decisions. 展开更多

As an important building block for the synthesis of angiotensin-converting enzyme inhibitors,ethyl(R)-2-hy-droxyl-4-phenylbutanoate[(R)-HPBE]has attracted increasing attention.The key to industrial biosynthesis of(R)-HPBE is a biocatalyst that efficiently reduces ethyl 2-oxo-4-phenylbutanoate(OPBE)with high R-enantiose-lectivity.This paper proposed a strategy for identifying key residues involved in enantioselectivity control based on per-residue free energy decomposition and sequence conservatism analysis.Using this strategy,4 noncon-servative sites with high energy contribution to binding of OPBE were chosen as engineering targets,generating variant Mu27 with 99%conversion and 98%(R)ee value at substrate loading of up to 500 mmol/L.MD simu-lations suggested the higher stability and formation probability of Mu27-OPBEproR prereaction state as key rea-sons for the excellent R-enantioselectivity of Mu27 towards OPBE.The success in this study provides a viable approach for rational design of alcohol dehydrogenases with high enantioselectivity towards unnatural substrates. 展开更多

The political essence of Russian conservatism is to respect the historical tradition and take a development path aligned with Russia's national conditions.Since Putin came to power,Russian conservatism has developed into the mainstream official ideology,becoming the core concept of Russia's current domestic and foreign policies.Russian conservatism is not only the guiding principle of Russia's national foreign policy,but it is also the moral banner of Russia's diplomacy,which reflects its foreign cognition and value system.Under the guidance of conservatism,Russia's foreign policy has distinct offensive features,and Russia has intensified its efforts to counter the liberal international order dominated by the West.After the escalation of the Ukraine crisis,the status of conservatism as Russia's mainstream ideology has been further consolidated,exerting a comprehensive influence on foreign policy.Against the background of extreme sanctions and isolation from the United States and the West,Russia has turned its diplomatic attention to non-Western countries,hoping to build a new international order. 展开更多

In this paper, an improved splitting method, based on the completely square-conservative explicit difference schemes, is established. Not only can the time-direction precision of this method be higher than that of the traditional splitting methods but also can the physical feature of mutual dependence of the fast and the slow stages that are calculated separately and splittingly be kept as well. Moreover, the method owns an universality, it can be generalized to other square-conservative difference schemes, such as the implicit and complete ones and the explicit and instantaneous ones. Good time benefits can be acquired when it is applied in the numerical simulations of the monthly mean currents of the South China Sea. 展开更多

Subtropical forest in China has received much attention due to its complex geologic environment and bioclimatic heterogeneity.There have been very few studies addressing which climatic factors have shaped both distribution patterns and niche differentiation of species from this region.It also remains unclear whether phylogenetic niche conservatism retains in plant species from this biodiversityrich subtropical region in China.In this study,we used geographic occurrence records and bioclimatic factors of Prunus dielsiana(Rosaceae),a wild cherry species,combined with the classical ENM-based DIVA-GIS software to access contemporary distribution and richness patterns of its natural populations.The current distribution of P.dielsiana occupied a relatively wide range but exhibited an uneven pattern eastward in general,and the core distribution zone of its populations are projected to concentrate in the Wushan and Wuling Mountain ranges of western China.Hydrothermic variables,particularly the Temperature Seasonality(bio4)are screened out quantitatively to be the most influential factors that have shaped the current geographical patterns of P.dielsiana.By comparison with other sympatric families,climatic niche at regional scale showed a pattern of phylogenetic niche conservatism within cherry species of Ros aceae.The effect of habitat filtering from altitude is more significant than those of longitude and latitude.We conclude that habitat filtering dominated by limiting hydrothermic factors is the primary driving process of the diversity pattern of P.dielsiana in subtropical China. 展开更多

Granite-gneiss rock outcrop inselbergs are ancient stable ecosystems with old,climaticallybuffered infertile landscapes(OCBILs).Although inselbergs provide key ecosystem services,little is done for their conservation and,so far,a lot of their unknown evolutionary history has already been lost by human activities.Using a fine-scale approach,here we tested if habitat and environmental filtering(the inselberg’s harshness)affect the evolutionary diversity of an Atlantic Forest inselberg in Brazil.We recorded all trees with a diameter at breast height≥5cm in 20 plots in four habitat types(total sampled area of 0.8 hectares),from highest to lowest:island,hillside,foothill,and semideciduous forest(matrix).We also collected soil samples for chemical,textural and physical soil characterization.We fitted linear models to test the effects of soil and habitat on plotlevel metrics of phylogenetic diversity and structure,lineage diversity,phylogeneticβ-diversity,and evolutionary distinctiveness.We found that the upper inselberg habitats contain a distinct set of ancient,closely related,harsh-tolerant lineages,as well as a subset of lineages that persist under harsh conditions with a certain degree of water availability.The inferior inselberg habitats harbor higher lineage diversity than expected by chance.Soil strongly predicted evolutionary diversity.We concluded that soil depth,slope,nutrients and texture(environmental filtering)and habitat types and topography(habitat filtering)shape the evolutionary history contained in fine-scale inselberg habitats,which should encourage the conservation of these ancient ecosystems. 展开更多
