Although research on blood donation abounds, no studies have yet attempted to estimate the socio-economic value generated from Blood Donors Associations (BDAs).To fill this gap, the authors ran a Social Return on Investment (SROI) analysis on four units of the largest BDA in Italy, the Association of Voluntary Italian Blood Donors (“Avis”).This study used multiple methods for data collection and analysis. A systematic literature review helped the identification of proper financial proxies to highlight the economic value of the social and health impacts experienced by Avis members. A focus group with key informants gathered their views on the areas of impact selected for the analysis: early detection of diseases, adoption of healthier lifestyles, social capital, human capital, personal satisfaction and reinforcement of a ‘giving culture’.Primary data collection involved (a) an Activity Based Costing analysis (b) a self-reported questionnaire to 1.066 BDA members and unassociated donors enabling the comparison of the blood donation experience of these two groups. The SROI analysis resulted in four positive ratios, varying between €1.70 and €13.80.This study contributes to the knowledge on impact evaluations in TSOs. Policy implications refer to BDAs deserving financial and material support for their capacity to generate positive social impacts. 相似文献
The normal hematological values in various phases of the rat life provide a valuable guide to researchers and could be useful for experimental works. However, database information available on the literature are incomplete. Aim: This study aimed to present normal hematological parameters of young and aged rats.
Methods: Male and female rats were distributed into seven experimental groups with 1, 2, 3, 6, 12, 18, and 24 months of age. Blood samples taken from the tails were analyzed. Normal hematological values were determined for each age group.
Results: Rats showed a progressive weight gain with advancing age, predominantly after 3 months of life. With advancing age, differences were found on hematological parameters: some of them showed a progressive rise with age and others did not. Hemoglobin levels and hematocrit did not change while the number of circulating red blood cells suffered slight increase.
Conclusion: The present study determined the normal values for absolute and relative hematological parameters in Wistar rats from 2 to 24 months for male and female rats. The results can be used in studies of effects of aging, feeding, and medications on growing and aging rats. 相似文献
