We define ω-directedness, investigate various properties to determine whether they have this property or not, and use our results to obtain easier proofs of theorems due to Laurence and Alster concerning the existence of a Michael space, i.e. a Lindelöf space whose product with the irrationals is not Lindelöf.

The heritability of schizophrenia and most personality traits has been well established, but the role of personality in susceptibility to schizophrenia remains uncertain. The aim of this study was to test for an association between personality traits and Neurological Soft Signs (NSS), a well-known biological marker of schizophrenia, in non-psychotic relatives of patients with schizophrenia. For...

OBJECTIVES To compare Cloninger's dimensions of temperament and character in patients with bipolar I disorder (BP-I) and healthy controls from the general population. MATERIALS AND METHODS This cross sectional study included 96 BP-I patients (according to DSM-IV-TR criteria) that were admitted to a psychiatric hospital in Iran due to an acute episode of mania or depression, or a mixed episode...

The purpose of this study was to examine the effect of case segmentation schemes in problem-based learning (PBL) on the development of problem-solving skill, self-directedness and technical knowledge. Seventy-four dental education students were randomly assigned to 12 PBL groups. Six groups experienced PBL cases that were formatted in short segments and six groups experienced PBL cases that wer...

Objective: In recent years, interpersonal relationships have become more complex and increasing number of people suffers from seclusion and loneliness. Early maladaptive schemas (EMSs), important cognitive structures, are expected to have a profound effect on interpersonal relationships. The present study aimed to investigate the relationship between EMSs and interpersonal problems among univer...

Object-Oriented database systems (OODBMS) are well known for modeling complex and dynamic application domains. Typically OODBMS have to handle large and complex structured objects whose values and structures can change frequently. Consequently there is a high demand for systems which support temporal and versioning features in both objects (or database population) and schema. This paper present...

Schema matching is fundamental in classical database application domains, such as data integration and data warehousing. In this talk, we survey and express our position with respect to three approaches that address schema matching. The first and oldest approach, that we call the syntactic approach, is to align two schemas based on syntactical hints, such attribute data types and naming (syntac...

There are clear advantages to using biomarkers and surrogate endpoints, but concerns about clinical and statistical validity and systematic methods to evaluate these aspects hinder their efficient application. Section 2 is a systematic, historical review of the biomarker-surrogate endpoint literature with special reference to the nomenclature, the systems of classification and statistical metho...

Data integration systems often provide a uniform query interface, called a mediated schema, to a multitude of data sources. To answer user queries, such systems employ a set of semantic matches between the mediated schema and the data-source schemas. Finding such matches is well known to be difficult. Hence much work has focused on developing semi-automatic techniques to efficiently find the ma...

Image-schemas (e.g. CONTAINER, PATH, FORCE) are pervasive skeletal patterns of a preconceptual nature which arise from everyday bodily and social experiences and which enable us to mentally structure perceptions and events (Johnson 1987; Lakoff 1987, 1989). Within Cognitive Linguistics, these recurrent non-propositional models are taken to unify the different sensory and motor experiences in wh...
