What mechanisms underlie aging? One theory, the wear-and-tear model, attributes aging to progressive deterioration in the molecular and cellular machinery which eventually lead to death through the disruption of physiological homeostasis. The second suggests that life span is genetically programmed, and aging may be derived from intrinsic processes which enforce a non-random, terminal time inte...

OBJECTIVE Callous-unemotional (CU) traits in childhood are a developmental precursor to psychopathy, yet the origins and etiology of CU traits are not known. We examined CU traits among 12-year-old children exposed to severe early deprivation and evaluated whether a high-quality foster care intervention mitigated the development of high levels of CU traits. METHOD Participants were from the B...

Medical officers and Health Care workers (or simply health workers) are the most people that impacted by Covid-19. Asymptomatic pre-symptomatic keep moving to different workplaces caused unoptimized protocols. Proper heatlh protocols in field is needed because there still a lot of poor indecent Personal Protective Equipments (PPE) being used workers. This research focused on correlation adheren...

Four fat-tailed ewes from an indoor flock (n=40) were examined for recumbency and depressive nervoussigns. They were from a seemingly nonpregnant group of the flock that had been diagnosed bytransabdominal ultrasonography. The ration consisted of mainly wheat straw since their separation from thepregnant group. Detection of pregnancy on abdominal palpation along with depressive nervous signs an...

Otoliths are structures located in the inner ear cavity of all teleost fish and serve as a balance organ and also aid in hearing. They have been used traditionally to obtain information about the taxon, age and size of fishes. This is very important because age, growth rate, and mortality rate are three of the most influential life history characteristics controlling the productivity of fish po...

A sexually dimorphic characteristic, the second to fourth digit ratio (2D:4D ratio), has been shown to reflect the prenatal concentration of sex steroid hormones and to correlate with many personality, physiological, and life history traits. The correlations are usually stronger for the right than the left hand. Most studies have shown that the 2D:4D ratio does not vary with age or postnatal co...

We contrasted the long-term mate preferences, reported developmental experiences, life history traits, and current personal traits of low-income women who reproduced with a single man (n = 222), two or more men (n = 145), or had not yet reproduced (n = 106). The mate preferences of the three groups were more similar than different, suggesting that group differences in reproductive strategy may ...

UNLABELLED PREMISE OF THE STUDY We examined two accounts of the relationship between breeding system and life history variation in a clade of evening primroses (Oenothera, Onagraceae): (1) selection for reproductive assurance should generate an association between self-compatibility and monocarpy and (2) phylogenetic conservatism leads to retention of breeding system and life history traits ...

Sexual conflict theory suggests that female breeding success is strongly influenced by individual life history and environmental conditions and is much less affected by mate availability. Female mating failure due to a shortage of males remains poorly studied and understood. We present data on the effects of male availability on female breeding success in a wild colony of yellow ground squirrel...

This article revisits the operation of Football (Offences) Act (FOA) 1991 30 years after its enactment. FOA was introduced following recommendations Taylor Report 1990 as part a raft measures looking to balance spectator safety against threat football crowd disorder. Providing targeted and largely uncontroversial restrictions on spectators, seemingly popular with police clubs, criminalises thro...
