The economic impact of audit failures
2022
This paper examines the economic consequences associated with an audit failure in the field of statutory auditing services, by analyzing changes in the audit firm’s market share around the time of the investigation process undertaken by the Spanish Public Oversight Board. We explore the variations in audit market share by applying the difference in differences method to a treatment group of 70 sanctioned audit firms and a matched control group of 70 non-sanctioned audit firms. The period of analysis covers the years from 1999 to 2015. Our results show that the sanctioned audit firms suffered a significant decrease in their relative number of clients. Moreover, this measure of market share d…
Multi-beam cooperative frequency reuse for coordinated multi-point transmission
2010
Coordinated multi-point (CoMP) joint transmission is considered in the 3rd generation partnership project (3GPP) long term evolution (LTE)-advanced as a key technique to mitigate inter-cell interference and improve the cell-edge performance. To effectively apply CoMP joint transmission, efficient frequency reuse schemes need to be designed to support resource management cooperation among coordinated cells. However, most of the existing frequency reuse schemes are not suitable for CoMP systems due to not considering multi-point joint transmission scenarios in their frequency reuse rules. In addition, the restrictions of frequency resources in those schemes result in a high blocking probabili…
Organisation and Context, Efficiency and Equity of Educational Systems: what PISA tells us
2005
05065http://www.wwwords.co.uk/eerj/; International audience; After describing both average scores, dispersion, and social inequalities in achievement in the various countries included in the latest Programme for International Student Assessment (PISA) study, this article relates those ‘products' to country economic and cultural characteristics. It then explores relations between student scores and a number of institutional characteristics of countries' educational systems. Results show that relations exist between average scores and certain institutional or pedagogical practices such as grade repeating or tracking. A high degree of social inequality in achievement proves to be associated wi…
Effects of school climate and teacher self-efficacy on job satisfaction of mostly STEM teachers: a structural multigroup invariance approach
2020
Abstract Background Identification and retention of effective teachers in STEM education play cardinal roles in teacher recruitment exercises worldwide. Studies on factors that characterize effective teachers have therefore gained popularity in recent times. Teacher self-efficacy, job satisfaction and school climate are among other factors that have attracted global attention. Thus, proper understanding of the relations between these factors is equally important. The purpose of this study is to validate and cross-validate a model of direct/indirect effects of school climate and teacher self-efficacy on job satisfaction. Results The data used for the current study are extracted from a public…
: The pupils' learning in their context : the effects of the composition of the school environment
2003
Whilst we admit to recognising the contextualised character of pupils' learning, the no less essential influence of the parameters of the school or social context remains a relatively unemplored field. Of course, the mobility of school effectiveness amply demonstrates the influence of the school of class attended by the pupils on their progression. But in the search for general factors of effectiveness, this trend has had few questions asked of it concerning the relationship with the characteristics of the pupil public. However, all work carried out on the impact of the forms of grouping of the pupils shows that both the average level of the group and the social composition (known in the An…
Do school resources increase school quality ?
2010
The aim of this paper is to verify whether school resource factors have an impact on the quality of education. This latter is measured with the help of a unique database on student scores in international skills tests. The general difficulties inherent in this type of study are the possibility of endogeneity bias and measurement errors. After estimation bias correction, we show that improvement in the quality of educational systems does not necessarily require an increase in school resources. When an alternative indicator of the performance of educational systems is used, our results are confirmed. Consequently, one should remain cautious about recommending purely financial measures to impr…
Efficacité comparée de l'enseignement public et privé au Cameroun
2010
In this thesis, we treat with the efficiency compared by the state education and by the private education in Cameroon. The current educational system carries the marks of colonial period. The school is crossed by three stages the school before the colonization, the school during the colonization and the school after the colonization. The current educational system is characterized by a strong educational request and an insufficient educational offer. The redoubling and the abandonments are frequent and raised. The educational system is little effective in general. Two educational sub-systems inherited from colonial period work, the one French speaker and the other English speaker. Two secto…
El boletín Faraday (1928-29) y las relaciones entre historia y didáctica de las ciencias
2021
Faraday ha sido considerada una de las primeras publicaciones especializadas en didáctica e historia de la ciencia en España. Sin embargo, hasta la fecha su recuperación y estudio se revelaba pendiente. A través del análisis inédito de esta publicación de principios del siglo xx, se abordan las relaciones entre historia y didáctica de las ciencias desde una mirada diacrónica. Dicho análisis ha puesto de manifiesto cómo la didáctica de las ciencias contribuyó a impulsar la forja disciplinar de la historia de la ciencia y cómo esta última nutrió a la didáctica de las ciencias de un amplio sustrato metodológico y epistemológico. Este análisis también ha ofrecido varios elementos de reflexión p…
