We re-examine the original Group Lasso paper of Yuan and Lin (2007). The form of penalty in that paper seems to be designed for problems with uncorrelated features, but the statistical community has adopted it for general problems with correlated features. We show that for this general situation, a Group Lasso with a different choice of penalty matrix is generally more effective. We give insigh...

The present report provides an overview of terminology studies in audiology including topics and study characteristics, as well as categorizing the main issues. The goals are to improve the understanding of the current issues for terminology in audiology and to provide some basic information that will be useful to develop an international standard. Search procedures were completed over two phas...

bonding brackets to the enamel surface has gained much popularity today. new adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. a considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose. previous studies have used variety of test designs. this diversity in...

PURPOSE Our study aimed to examine psychometric properties and cross-cultural utility of the Behavior Assessment System for Children-2, Parent Rating Scale-Child (BASC-2 PRS-C) in Korean children. MATERIALS AND METHODS Two study populations were recruited: a general population sample (n=2115) of 1st to 6th graders from 16 elementary schools and a clinical population (n=219) of 6-12 years old ...

Twelve Lipid-Research Clinic laboratories performed automated cholesterol analyses on four control-serum pools of known cholesterol concentration, using the Liebermann-Burchard reaction. The analyses were done during a two-year period, with the same standards, methodology, and quality-control procedures. Estimates of analytical bias, variability, and short- and long-term trends for each instrum...

The pathophysiological assessment of joint properties and voluntary motion in neurological patients remains a challenge. This is typically the case in cerebellar patients, who exhibit dysmetric movements due to the dysfunction of cerebellar circuitry. Several tools have been developed, but so far most of these tools have remained confined to laboratories, with a lack of standardization. We repo...

− In the uncertainty budget of Rockwell C hardness (HRC) tests, geometric error of the Rockwell diamond indenter is a major contributor. The geometric calibration of Rockwell diamond indenters has been a key issue for Rockwell hardness standardization. The National Institute of Standards and Technology (NIST) developed a microform calibration system based on a stylus instrument for the geometri...

recent years have witnessed a parallel and seemingly contradictory trend towards both the standardization and the customization of healthcare and medical treatment. here, we explore what is meant by ‘standardization’ and ‘customization’ in healthcare settings and explore the implications of these changes for healthcare delivery. we frame the paradox of these divergent and opposing factors in te...

Purpose: To validate an instrument to assess fluid control in outpatient hemodialysis patients, using the NANDA International (NANDA-I), Nursing Interventions Classification (NIC), and Outcomes (NOC) terminologies.Methods: A methodological study was carried out two steps: (1) construction of composed operational definitions defining characteristics nursing diagnosis Excess volume, indicators NO...
