Research into the impact of lobbying on accounting standard setting has a decades-old tradition in international accounting research. Due to the changes brought about by the European Union’s IAS regulation as well as the application of new research methods this research topic has recently gained renewed relevance. The present article surveys the empirical literature on lobbying the accounting standard setter in Anglo-Saxon countries, discusses the transferability of this literature’s results to the new situation in the European Union and offers a perspective on current research topics.  相似文献

Krämer (Sankhy $\bar{\mathrm{a }}$ 42:130–131, 1980) posed the following problem: “Which are the $\mathbf{y}$ , given $\mathbf{X}$ and $\mathbf{V}$ , such that OLS and Gauss–Markov are equal?”. In other words, the problem aimed at identifying those vectors $\mathbf{y}$ for which the ordinary least squares (OLS) and Gauss–Markov estimates of the parameter vector $\varvec{\beta }$ coincide under the general Gauss–Markov model $\mathbf{y} = \mathbf{X} \varvec{\beta } + \mathbf{u}$ . The problem was later called a “twist” to Kruskal’s Theorem, which provides conditions necessary and sufficient for the OLS and Gauss–Markov estimates of $\varvec{\beta }$ to be equal. The present paper focuses on a similar problem to the one posed by Krämer in the aforementioned paper. However, instead of the estimation of $\varvec{\beta }$ , we consider the estimation of the systematic part $\mathbf{X} \varvec{\beta }$ , which is a natural consequence of relaxing the assumption that $\mathbf{X}$ and $\mathbf{V}$ are of full (column) rank made by Krämer. Further results, dealing with the Euclidean distance between the best linear unbiased estimator (BLUE) and the ordinary least squares estimator (OLSE) of $\mathbf{X} \varvec{\beta }$ , as well as with an equality between BLUE and OLSE are also provided. The calculations are mostly based on a joint partitioned representation of a pair of orthogonal projectors.  相似文献

The acceptance-rejection algorithm is often used to sample from non-standard distributions. For this algorithm to be efficient, however, the user has to create a hat function that majorizes and closely matches the density of the distribution to be sampled from. There are many methods for automatically creating such hat functions, but these methods require that the user transforms the density so that she knows the exact location of the transformed density’s inflection points. In this paper, we propose an acceptance-rejection algorithm which obviates this need and can thus be used to sample from a larger class of distributions.  相似文献

The objective was to compare the applicability of and results provided by the two measures of sickness absence used most often within the Swedish social insurance administration (that is, unadjusted sick-leave rate and adjusted sick-leave rate) and five measures suggested by epidemiological researchers. Data consisted of four cross-sectional data sets of registry sick-leave data covering four separate years (1997-2000) in three counties. In total 454,000 persons qualified for sickness insurance and aged 20-64 years were included. The two measures used within the social insurance administration and three of the five measures suggested by epidemiological researchers revealed sex-related dissimilarities in absence patterns that indicated that women had more sickness absence than men. However, in marked contrast to those results, two of the epidemiologically based measures (i.e., length of sickness absence and duration of sickness absence) instead showed highly comparable rates of sick leave for men and women, and such information is seldom obtained, albeit definitely of importance, when trying to make a correct assessment of sickness absence. The measure of sickness absence that is used influences the findings and should therefore be chosen with care. Complementing the measures used in the social insurance administration by five measures suggested by epidemiological researchers provided a more informative and comprehensive picture of sickness absence in a population. Further investigations into the effect of using different measures is needed, as well as international consensus on what to call different measures.  相似文献

Adequate work assessments are a matter of importance both for individuals and society [5,29,31,38,40,46,52]. However, there is a lack of adequate and reliable instruments for use in work rehabilitation [14,15,20,21,31,44]. The purpose of this study was to develop and evaluate an observation instrument for assessing work performance, the AWP (Assessment of Work Performance). The purpose of the 14-item instrument is to assess the individual's observable working skills in three different areas: motor skills, process skills, and communication and interaction skills. This article describes the development and results of preliminary testing of the AWP. The testing indicates a satisfactory face validity and utility for the AWP and supports further research and testing of the instrument.  相似文献

Musculoskeletal disorders (MSDs) have a multifactorial etiology. Therefore, a holistic approach to identifying target groups for primary/secondary prevention is essential. In this study, an exploratory person-oriented approach was applied, using cluster analysis of variables related to physical and psychosocial work conditions, and conditions in the private sphere, on a data set of 1,341 Swedish women and men who had not sought care for MSDs the 6 months preceding enrollment in the study. Three groups at risk and five "healthy" groups regarding MSDs were identified. Two of the risk groups had a strained situation regarding psychosocial work conditions or domestic/family conditions, respectively. The majority of individuals in these groups were women. The third risk group had a strained situation regarding both physical and psychosocial work conditions. This group consisted largely of men working in male-dominated jobs. The five healthy groups had low/moderate metabolic demands at work, and all of them having high proportions of subjects with moderate to high education, and fairly even distributions of men and women. In conclusion, the results indicate that gender-specific working and living conditions are associated with an increased risk for MSDs. The identification of these subgroups in the population may facilitate a selective prevention approach.  相似文献

The aim of this article is to explore welfare policies for children in five Nordic countries—Denmark, Finland, Iceland, Norway and Sweden—and in that context identify what kinds of issues and challenges social work is currently facing. The data reviewed consist of policy documents, law texts, official reports, statistics, professional texts, and previous research. Policies and laws on children's protection; provisions, including policies on state benefits and care for children; and the autonomous integrity of children in terms of the norms and policies concerning their participation, in particular in public everyday life, are analysed from a historical perspective. Hence, future challenges for social work are analysed in light of the past. Our conclusion is that social workers have a unique opportunity, based on their close encounters with children as clients, to work for the realisation of children's rights. Furthermore, by applying a holistic perspective to issues of childhood and parenthood, social workers can contribute to the development of knowledge on how welfare systems can meet the challenges brought about by the new ideas of children's rights, social changes, globalisation, and the new ideological concepts of risk that have arisen in child welfare.

Artikkeli tarkastelee lasten hyvinvointipolitiikan kehitystä viidessä Pohjoismaassa—Tanskassa, Suomessa, Islannissa, Norjassa ja Ruotsissa—ja sen valossa sitä millaisia kysymyksiä ja haasteita tämän päivän lasten hyvinvoinnin parissa tehtävä sosiaalityö kohtaa. Artikkelissa on käytetty aineistona erilaisia politiikkadokumentteja, lakeja, julkisia raportteja,tilastoja, professionaalisia kirjoituksia sekä aiempaa tutkimusta. Artikkelissa analysoidaan historiallisesta näkökulmasta lastensuojelun, sosiaalipalvelujen, lapsille suunnattujen sosiaalisten tukien sekä lasten osallistumista koskevia normeja ja toimintapolitiikkaa. Sosiaalityön tulevaisuushaasteita analysoidaan menneisyyden valossa. Johtopäätöksemme on, että sosiaalityöntekijöillä on ainutlaatuinen mahdollisuus, joka perustuu heidän läheisiin työskentelysuhteisiinsa vaikeissa elämäntilanteissa olevien lasten kanssa, olla lasten oikeuksien todellisia toimeenpanijoita. Lisäksi lapsuuden ja vanhemmuuden näkökulmat yhdistävästä toimintapaikastaan käsin juuri sosiaalityöntekijät voivat vaikuttaa tutkimukseen ja kehittämiseen niin, että hyvinvointipalvelut ja –etuudet kohtaisivat nykyistä joustavammin lasten oikeuksien, yleisen yhteiskuntamuutoksen, globalisaation ja kovin ideologisena pitämämme riskiajattelun haasteet.  相似文献

The demand for information and transparency from listed corporations has recently increased. In spite of an increased demand for mandatory disclosures from regulators, corporations choose to voluntarily disclose additional information in order to satisfy demands from the capital market. However, the extent and content of information in those voluntary disclosures vary across corporations. The aim of this study is to explain the variation in the content of information in voluntary disclosures by listed corporations. The analyses are based on data collected from 431 annual reports from corporations listed on the Stockholm Stock Exchange during the years 2002 and 2005. The findings support explanations from agency theory and positive accounting theory that size and the debt ratio are positively correlated with the content of information in voluntary disclosures. Corporations with a high share of management ownership disclosed less information than corporations with a low share of management ownership. The study also shows that variations in voluntary disclosures can be explained by factors derived from institutional theory and ‘international capital market pressures’. The results indicate that foreign ownership and international listing to some extent have a positive effect on the content of information in voluntary disclosures. Industry was another factor that had a significant influence on voluntary disclosures. One important finding is that regulation to some extent can stimulate voluntary disclosures; our results did not indicate an ‘unintended chilling effect’ due to too much regulation. In general, the corporations disclosed more voluntary information after the introduction of IFRS.  相似文献
