在双层绕组中,线圈的节距y小于极距τ.这是因为正弦交流电会产生多次谐波,其中的5、7次谐波对电机转动力矩的影响最大,在现实生活中,为了有效地削弱磁场中的高次谐波,改善电动机运行性能,我们采用y=T,这是合理的.  相似文献

Tax compliance denotes the act of reporting and paying taxes in accordance with the tax laws. Current social science scholarship on tax compliance can almost entirely be divided into behavioural psychology analyses and critical tax studies. This article, which presents two cases of how tax compliance is constructed, challenges the explanatory reaches of today's social science approaches, arguing that an alternative approach to understanding tax compliance is worthwhile exploring. This other choice of approach, inspired by actor–network theory (ANT), adopts a more practice-oriented focus that studies tax compliance where it takes place as well as what it is made of. Consequently, this article argues that tax compliance is a socio-material assemblage and that complying is a distributed action. The article concludes by highlighting how an ANT approach contributes to the further theoretical development of social science studies of taxation.  相似文献

This article highlights how recent reforms to the auditing and assessment of local public services in England suggest there will be a shift from panoptical to ‘synoptical’ monitoring approaches. This is because the UK Government has abolished its centralised monitoring regime and instead required local authorities to publish a range of financial and performance datasets online, ostensibly so that citizens can hold organisations to account directly. However, the complexity and raw nature of these data, along with the sidelining of professional auditors, will result in most citizens being either unable or unwilling to undertake this task. As such, the proposed ‘synoptical’ approach will not materialise. Indeed, other legislative changes will mean that outsourcing firms effectively become the new, unaccountable observers of local public sector bodies within an enduring panoptical system. In many cases these companies will then assume responsibility for delivering the same services that they have assessed.  相似文献

Keynes (1930) and Samuelson (1965) proposals open the possibility of matching predictability and efficiency, as evidenced by the seminal study by Fisher (1930). Recent findings suggest that the foreign exchange market gradually incorporates relevant information allowing the formation of prices in a rational manner but not randomly. Models of exchange rate by term based on asset valuation suggest that the inclusion of risk in the spot rate increases the degree of predictability. The results show that after incorporating an accurate measure of risk, predictability of medium term foreign exchange rate increases.  相似文献

The adoption of IASB’s standards has represented, in the European Union, an important effort of harmonization towards the financial reporting comprehensiveness, reliability, relevance and comparability. This paper seeks to highlight the importance of Information Compliance Indexes (ICI), based on the accounting standards, as a proxy for reporting quality awareness. This approach is evidenced through an illustrative example about disclosures on deferred taxes, as required by IAS 12. This standard prescribes the accounting treatment for current taxes, deferred assets and liabilities. These issues are usually perceived by stakeholders as indicators of companies’ continuity and potential future returns. Based on non-financial listed companies of Euronext Lisbon regulated market, with reference to the end of fiscal years 2008 and 2012, an information compliance index was performed, based on that accounting standard. Then, this index was regressed with a set of performance and control indicators. Evidences have provided several statistical significant insights, which corroborate the findings that information compliance and disclosure levels depend from several performance and control indicators.  相似文献

The attraction of foreign direct investment seeks, among other things, to increase the productivity of local companies through knowledge spillovers. However, the empirical evidence in this regard is contradictory. One influential factor is the absorptive capacity of the local companies. This article analyzes the effect of the presence of former employees of multinational corporations as employees of local companies, on the absorptive capacity of said companies. The study was done in Costa Rica, a country known for its successful strategy in the subject matter. The data come from a survey applied to 1167 companies by the Observatorio Costarricense de las Pymes in 2011. It was found that the hiring of former employees of multinational corporations by local companies has a positive effect on the index of absorptive capacity of companies in all productive sectors. Specifically, this hiring of former employees increases the index of absorptive capacity by nine percentage points, with differences by sector and the size of the company.  相似文献

Using the economic and financial performance data of international companies for the exploration, and exploration–extraction (E&E) of oil, as well as the patterns of institutional situation and orientation with the government market and national oil companies or NOCs that receive project offers, we analyze the institutional development and behavior patterns by type of E&E contract, following the strategic actor approach, or the so-called agency theory. Additionally, in light of Mexico's energy reform being implemented between 2015 and 2019, we analyzed the types of license contracts compared to those for production and shared profit. Subsequently, it was determined-through panel data methods in the analysis of 17 companies between 2005 and 2015-that global companies present bigger yields and commitments compared to specialized companies, confirmed by their net income and returns on equity or ROE.  相似文献
