The purpose of this review was to examine sport officials’ motivation and passion to become and remain a referee in today’s sport climate. There are endless accounts of misconduct towards officials from participants, coaches, parents and fans. This review examined the research evidence that explained why officials continue to work in their sport and tried to determine what motivations were fact...
with the aim of controlling malaria by reducing vector population, the effects of antibodies produced against salivary glands and deglycosylated midgut antigens of anopheles stephensi mosquitoes on fecundity and longevity of the same species were tested. three deglycosylated preparations of midgut and two preparations of salivary glands were produced, conjugated with aluminum hydroxide gel, and...
Although theories in both evolutionary biology and economics predict that an individual’s health should be associated with the individual’s time preference, no prior study has been done to empirically support or refute such predictions. By collecting detailed measures of health, time preference, and expected longevity on a sample of individuals in townships around Durban, South Africa, this stu...
Despite the perceived value of DSS in informing environmental and natural resource management, DSS tools often fail to be adopted by intended end users. By drawing together the experience of a global group of EDSS developers, we have identified and assessed key challenges in EDSS development and offer recommendations to resolve them. Challenges related to engaging end users in EDSS development ...
The data set used in this study contained 8793 records of lamb's longevity (days) from 320 sires and 2349 dams collected during 1989 to 2014, from the Lori-Bakhtiari flock at Shooli station in Shahrekord, Iran. Genetic parameters (partitioned into autosomal, sex-linked and maternal) and breeding values of cumulative lamb's longevity from birth up to yearling age (at 1, 2, 3, 6, 9 and 12 months)...
The objective of this study was to evaluate non-genetic factors affecting longevity and survival of Guilan sheep from birth to yearling. Longevity and survival records of 41037 lambs born from 496 rams and 10256 ewes of Guilan sheep were analyzed using linear and Weibull models. Results indicated that the overall mean of longevity was 1260.84 days. The fixed effects of flock, dam age, sex, year...
background: we aimed to identify the role of sirt 6 gene polymorphism rs350846 in human longevity. methods: sirt 6 c/g genotypes were determined using taqman snp genotyping assays in 169 long-lived inhabitants (lg group aged 90-110 yr), 158 healthy internal controls (internal control group; aged 26-82 yr) and 176 healthy external controls (external control group; aged 20-82 yr) without a family...
longevity, aging and its prevention
Chrysanthemum is one of the most important ornamental and medicinal plants in the world. In this study, diversity among 50 genotypes of chrysanthemum morifolium was analyzed using phenologic and morphologic traits. The variation between studied genotypes showed a significant difference for all traits and coefficient of genetic variations for most traits was greater than 40%. The highest general...
