Seedstock producers are interested in making as rapid genetic progress toward their defined breeding goals as is possible since this will enhance the profitability and long-term success of their breeding operations. These breeders need signals that will tell them how effective their breeding program has been and where problem areas might occur. PIGBLUP tries to provide these signals to breeders...
Genetic parameters for dairy performance traits were estimated, breeding values for the traits of all breeding sires and cows were predicted and the genetic trends were estimated using the breeding values in the Central Cattle Breeding Station (CCBS). A total of 3,801 records for Bangladeshi Local, 756 records for Red Sindhi and 959 records for Sahiwal covering the period from 1961 to 1997 were...
purpose: to investigate the proportion and time trend of second-eye senile cataract surgery (secs) in a high-turnover academic center in iran. methods: in this cross-sectional study, samples were selected among all records of senile cataract surgery based on the international statistical classification of diseases and related health problems, 10th revision (icd-10) during four consecutive years...
Genetic parameters, genetic trends, and genetic progress of carcass traits were estimated for 12,447 Nellore individuals from different Brazilian herds. The following carcass traits were analyzed: visual body scores of conformation (CONF), precocity (PREC), and muscularity (MUSC); rump width (RW) and rump length (RL), body size (frame); and ultrasound evaluation of ribeye area (REA), backfat th...
Purpose – The purpose of this paper is to encompass the assessment of the effectiveness of the digital library and the value of multidisciplinary databases in terms of user preferences and use frequency by academic ranking. Design/methodology/approach – This paper compares the results of two survey questionnaires carried out in 2002 and 2005. It examines the level of awareness by academic staff...
There are noted disparities by ethnicity, race, age, gender, and socioeconomic status in the reported use of and access to cancer information. Missing from this list of variables that predict these disparities are specific geographic locales, such as Appalachia, a region recognized as a medically underserved, “special population”. Through a secondary analysis of NCI’s 2003 HINTS dataset, we are...
The development of a prophylactic vaccine to prevent infection with oncogenic subtypes of human papillomavirus (HPV) is an important step in reducing cervical cancer incidence and mortality. However, national data indicate that only 37% of 13- to 17-year-old females have initiated the vaccine series. Prior studies have examined demographic, medical history, and psychosocial variables associated...
In visual surveillance face detection can be an important cue for initializing tracking algorithms. Recent work in psychophics hints at the importance of the local context of a face for robust detection, such as head contours and torso. This paper describes a detector that actively utilizes the idea of local context. The promise is to gain robustness that goes beyond the capabilities of traditi...
disability weight ð1Þ YLL 1⁄4 Number of deaths life expectancy at the age of death ð2Þ DALY 1⁄4 YLD þ YLL ð3Þ The philosophical and methodological aspects of the DALY calculation have been described (and debated) in great detail (Murray 1994; Murray and Acharya 1997; for critiques, see, amongst others, Anand and Hanson 1997), and are summarized in the accompanying Hints and Kinks paper (Devlees...
The collaboration of faculty and library in Problem Based Learning (PBL) has led to an abundance of studies in the medical and health sciences. This article reports on the emerging roles of librarians in studies on PBL implementation during the past 10 years. The initial analysis revealed studies which focussed on the effects of PBL on library usage. However the trend has since evolved to studi...
