  A light-sensitive element for the diffusion transfer process which comprises a support having thereon a light-sensitive silver halide emulsion layer having associated therewith a yellow dye providing compound represented by the following general formula (I): wherein CAR represents a carrier moiety which is capable of releasing a diffusible dye from the compound in correspondence or counter-correspondence to development under alkaline conditions; Link represents a group connecting CAR with a diffusible dye; m represents 0 or 1; the dotted lines mean that at least one of the dotted lines is a bond; R¹ represents a hydrogen atom, an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group or a carbamoyl group; R² represents an alkyl group or an aryl group; and R³ represents an aryl group excepting an aryl group having the Hammett's σp value less than 0.01. The yellow dye providing compound has a dye moiety whose transferability is high and whose hue is excellent and provides a stable yellow dye image which does not substantially change hue over a wide pH range

• Interlocking Trajectories of Loss-Related Events and Depressive Symptoms Among Elders

  Objectives. As people age, their peers (who are also aging) become increasingly susceptible to health decline and death, implying potential growth in stressful loss-related events over time for the individual. Yet little research has examined trajectories of stress and their relationship to trajectories of depression among elders. The purpose of this research was to determine whether growth in loss-related events occurs for elders and whether stress growth is related to the well-known growth in depressive symptomatology in later life.Methods. Three waves of National Institute on Aging Established Populations for Epidemiologic Studies of the Elderly (Duke University site) data were used in the analyses. Latent growth curve models were estimated for stress. for depressive symptoms, and for stress predicting depression net of several covariates.Results. Findings include that (a) loss-events evidence clear growth across age at the aggregate level, but with Much variation within the sample, and (b) variation in growth in stress is strongly related to variation in growth in depressive symptoms.Discussion. The results suggest that stress in later life may be conceived of as a growth process, with strong consequences for trajectories of mental health.
