The nonlinear time series properties of unemployment rates: some further evidence

The time series properties of unemployment rates for Germany, Japan, the UK and the US are re-examined. Evidence of nonlinear structure in the residuals of the most parsimonious linear ARMA models is reported for all countries except Japan. Modelling this nonlinearity using SETAR models suggests strong asymmetry in unemployment dynamics and the presence of a possible limit cycle for the UK. However, residual diagnostics for these models indicate remaining structure. Alternative TAR models conditioned on past growth rates of industrial production yield substantial reductions in residual variance over both linear and SETAR counterparts, iid residuals in all cases other than the US, and threshold values at or very near zero, clearly identifying the asymmetric behaviour of unemployment during expansionary and contractionary phases of the business cycle.     

La oralidad y la escritura en el proceso de aprendizaje Aplicación del método aprende a escuchar,pensar y escribir

Research design is quasi-experimental, field, with four longitudinal assessments for two groups (one experimental and one control) of students with irregularity student. Intervention, learns listen-think-write (lltw) method. population, 488 students. With a sample conditioned (students with irregular registration) of 170 students from two university careers of accounting and administration, both manner, 24.3 years old. Material, Raven’s Progressive Matrices test and Learning strategies ACRA test. The impact obtained by the intervention (LLTW) was 23%, significant difference between follow-up evaluation 6 and 12 months. Regarding the improvement of learning skills in post-test measurement showed a general increase in average by 28%. Also it is necessary to say, the decline was failed subjects in the two groups evolving 12 months in control group was 3 to 4 and the experimental group was 1 to 2.     

User producer interaction in context

User producer interaction (UPI) increases chances for successful innovations. It is not always clear, however, what type of interaction is necessary in a particular context. This article identifies seven different types of UPI: constructing linkages, broadening, characterizing users, upstream involvement, first user enrollment, feedback, and downstream innovation. Specific contextual dimensions from which these UPI types derive relevance are discussed. The technological dimension of this context is conceptualized based on a distinction between types of technologies that differ in the degree to which they are customizable to user demands. Four case studies show that technological characteristics indeed matter for UPI, as do the heterogeneity of users and the phase of technology development.     

Global compliance with international accounting education guidelines

The International Accounting Education Guidelines (IAEG) of the International Federation of Accountants (IFAC) issued since 1982 specify the components for the Professional preparation to become a qualified accountant.

This paper presents the results of a survey of compliance conducted in fifty-four countries outside the USA with International Accounting Education Guidelines (IAEG), as issued by the International Federation of Accountants (IFAC). Its purpose is to provide a benchmark measure of compliance for current assessment of accounting education, and for reference in future studies. This study is the first attempt to examine compliance with IAEGs in all sectors of the world in which IFAC has members. The paper is divided into the following sections: international accounting education guidelines; survey questions; methodology; results; effectiveness of the guidelines, and summary and conclusions.     

Remittances,Monetary Policy,and Partial Sterilization

Remittances play a large and important role in certain economies, where they became a significant share of GDP. Official government records of these flows have been systematically improved since governments realized their importance, but a significant percentage of remittances remain unrecorded. This, together with the shadow economy, may pose a problem for monetary policy. This article uses a limited participation model to examine the differential effect that higher shares of remittances can have on monetary policy and describes the impact of remittances on a small open economy under partial sterilization. It demonstrates how a typical monetary shock will lead to a more pronounced liquidity effect when remittances become a higher proportion of GDP. It also shows that a positive remittance shock improves consumption and lowers interest rates, but as it also reduces work effort it momentarily lowers output. Such dynamics are exacerbated as the degree of partial sterilization is accentuated.     

Grocery shopping and an ageing population: research note

This study focuses on grocery shopping and an ageing population. It hypothesizes that as a population ages so there will be a change in preferences for certain service and product factors associated with grocery shopping. Survey responses were collected from 393 people and the results confirmed the expectations. To analyse the data, a multiplicative determinance model was used. The study concludes with a discussion of the implications of the findings for retailers.     

Institutional dimensions underlying public trust in information on technological risk

This paper examines the determinants of trust in public information on technological risk in a petrochemical complex located in Tarragona (Spain). Data from focus groups (eight) and a questionnaire survey (N = 400) are drawn together to analyse how two local communities exposed to major chemical hazards perceive information on risk and its sources. Results show how trust relies on two main factors, namely expertise and trustworthiness, that are significantly influenced by a third one, antagonism. Results also illustrate the relevance of the institutional context when understanding how communities give meaning to the available information on risk.
