The reproductive status of nonbreeding group members in captive golden lion tamarin social groups

Abstract: Reproductive activity is limited to only one female in many species of callitrichid primates (marmosets and tamarins): daughters and subordinate females do not produce offspring. A suppression of ovulatory cyclicity is responsible for the lack of reproductive activity in three species of callitrichids studied to date. This study evaluated the endocrine status of golden lion tamarins (Leontopithecus rosalia) housed as daughters or sons in family groups and of individuals housed in isosexual peer groups. Daughters 17 months of age and older and a subordinate female had high levels of estrogen excretion. Mean levels of estrogen excretion in these females were similar to those of nonpregnant, breeding adult females (17.14 ± 6.82 versus 11.93 ± 6.33 μg/mg creatinine, respectively). Estrogen profiles were similar to those of breeding adult females, with sinusoidal cycles in estrogen excretion. Younger daughters in family groups (10 and 12 months old) showed markedly lower levels of estrogen excretion (0.84 ± 0.58 μg/mg creatinine). Estrogen profiles lacked the sinusoidal nature of cycles in older daughters and breeding females, and elevations in estrogen excretion occurred frequently and remained elevated for 1 or 2 days. Plasma testosterone levels in males varied widely, but mean concentrations did not differ among males housed in different social conditions. These results suggest that older daughters and subordinate females may be capable of expressing normal ovarian function in the presence of a breeding adult female. This finding may account for two unusual observations in the lion tamarin: the high level of female-female aggression and the presence of groups in the wild with more than one actively breeding female.

BPR through ERP: Avoiding change management pitfalls

Abstract: ERP-led BPR implementation often leads to fundamental changes within an organization's structure, culture and management process. Literature cites that a fragmented approach to change management practices is the major reason for BPR failures. The purpose of this paper is to look at the change management process in companies where BPR was implemented through ERP, and thereby obtain some insight into the dynamics of this change process. Many ERP implementers are finding themselves in a position to re-engineer their existing processes to fit the software they are implementing. The paper uses a case study approach that investigates six change management issues at three diverse companies where ERP-led BPR was implemented. The paper shows that through close attention to the change management principles the ERP implementers must integrate the changes with company strategic objectives, and through detailed planning and workforce cultural changes navigate the new system.
