This chapter discusses the concept of resilience from a life span perspective informed by relational developmental systems theory. Resilience involves mutually benefi cial (adaptive) relations between characteristics of individuals (e.g., their self-regulation behaviors) and features of the ecology (e.g., resources promoting healthy development); these links may be represented as individual ←→ ...

perspectives on life span Life span should be considered within a larger biological framework concerned with life duration—a model where the end points of life for an individual do not necessarily correspond to the conventional events of birth PDR 29 Supp Carey.sp 7/6/06, 3:16 PM 1 2 L I F E S P A N : A C O N C E P T U A L O V E R V I E W and death. The concept of life span does not apply to ba...

Most people have experienced loneliness and have been able to overcome it to reconnect with other people. In the current review, we provide a life-span perspective on one component of the evolutionary theory of loneliness-a component we refer to as the reaffiliation motive (RAM). The RAM represents the motivation to reconnect with others that is triggered by perceived social isolation. Loneline...

Research in the field of aging recently has entered a new era. Model systems have begun to provide insight into cellular, molecular, and organismal changes that are related intimately to aging. One important approach has been the identification of genes that determine the life span of an organism. The very existence of genes that when mutated can extend life span suggests that one or a few proc...

Drosophila melanogaster seminal fluid proteins stimulate sperm storage and egg laying in the mated female but also cause a reduction in her life span. We report here that of eight Drosophila seminal fluid proteins (Acps) and one non-Acp tested, only Acp62F is toxic when ectopically expressed. Toxicity to preadult male or female Drosophila occurs upon one exposure, whereas multiple exposures are...

Inflammatory linear verrucous epidermal nevus (ILVEN) is a unilateral skin disorder which usually manifests in infancy or childhood. Female predominance, frequent leg involvement, pruritus, resistance to treatment, and a psoriasiform histologic pattern are other common characteristics of this disease. Atypical presentations of ILVEN have been described and include late onset in life, wide...

the life history of an acarid mite, tyrophagus putrescentiae (schrank), on fusarium graminearum clade was investigated at 25 â± 1â°c, 60 â± 5% rh and a photoperiod of 16: 8 (l: d) h. incubation period for egg hatch, larval and nymphal periods and adult longevity were 2.22 â± 0.06, 3.46 â± 0.12, 4.84 â± 0.16 and 10.05 â± 0.9 days, respectively. the average life span of males and females were 22....

Analysis of genetic interactions in the F2 of an intercross of (C57BL/6 x DBA/2) F1J revealed influences of genetic factors on life span. Females lived longer than males. Dilute brown females died sooner than females of other colors. H-2b/H-2b males died sooner than H-2b/H-2d or H-2d/H-2d males, except that among dilute brown males those of typeH-2b/H-2d died sooner. Cluster analysis suggested ...

In animals with internal fertilization, sperm competition among males can favor the evolution of male ejaculate traits that are detrimental to females. Female mating preferences, in contrast, often favor traits in males that are beneficial to females, yet little is known about the effect of these preferences on the evolution of male ejaculates. A necessary condition for female preferences to af...
