“Describe your occupation in a few words”, is a question answered by 44 000 Swedish twins. Each respondent was then manually categorized according to two established occupation classification systems. Would a clustering algorithm have produced satisfactory results? Usually, this question cannot be answered. The existing quality measures will tell us how much the algorithmic clustering deviates ...

The cardiomyopathies are an important and complex group of heart muscle diseases with multiple etiologies and heterogeneous phenotypic expression.1 Awareness and knowledge of these diseases in both the public and medical communities have historically been impaired by periodic confusion surrounding definitions and nomenclature. Therefore, formal and systematic classifications have traditionally ...

This paper utilizes Chinese stock data to provide further evidence on the power of limited attention theory in explaining post-earnings announcement drift. As retail investors prevail China and they are easily distracted by market swings, we should expect severe problems, resulting larger underreaction firm information higher sensitivity movement, i.e., so-called “market movement effect”. After...

Using the 138,751 patents filed in 2006 under the Patent Cooperation Treaty, coclassification analysis is pursued on the basis of threeand four-digit codes in the International Patent Classification (IPC, 8 edition). The co-classifications among the patents enable us to analyze and visualize the relations among technologies at different levels of aggregation. The hypothesis that classifications...

arrangements for physical illness. Patients are to be admitted without formality?so that even voluntary status is an unnecessary concept: safeguards and standards of individual care are to be those that any doctor or hospital authority would naturally employ. The needs of the patient are more important in determining the type of hospital he goes to than scientific classifications. All this mean...

The service sector is extraordinarily heterogeneous. Since existing service classifications provide useful yet partial perspectives on this diversity, this paper reconciles and integrates distinct service taxonomies into a coherent and pragmatic typology which follows three dimensions: demand orientation, knowledge-intensity and technology-intensity. A regional analysis of services employment i...

This paper discusses about the solution of fuzzy Volterra integral equation of first-kind (F-VIE1) using spectral method. The parametric form of fuzzy driving term is applied for F-VIE1, then three classifications for (F-VIE1) are searched to solve them. These classifications are considered based on the interval sign of the kernel. The Gauss-Legendre points and Legendre weights for arithmetics ...

I study the influence of minimum quality standards in a partial-equilibrium model of vertical product differentiation and trade in which duopolistic firms face quality-dependent costs and compete in quality and price in two segmented markets. Three alternative standard setting arrangements are Full Harmonization, National Treatment and Mutual Recognition. Under either alternative, standards can...
