Abstract:
The African Grey parrot (Psittacus erithacus) is one of the most popular avian pets in exotic animal practice. In this study, blood samples (n = 459) from healthy African Grey parrots (n = 239) were collected for haematological testing. Reference intervals were determined according to the guidelines of the American Society of Veterinary Clinical Pathology with the Reference Value Advisor (v2.1) freeware. The calculated reference intervals (RIs) were: packed cell volume 38–59%; haemoglobin 105–154 g/l; RBC 2.3–3.3 10<sup>6</sup>/µl; MCV 145.5–199.7 fl; MHC 38.3–55.6 pg; MCHC 232–313

Abstract:
The Congo African grey parrot (Psittacus erithacus, PER) is an endemic species of Central Africa, valued for its intelligence and listed as vulnerable due to poaching and habitat destruction. Improved knowledge about the P. erithacus genome is needed to address key biological questions and conservation of this species. The P. erithacus genome was studied using conventional and molecular cytogenetic approaches including Zoo-FISH. P. erithacus has a ‘typical' parrot karyotype with 2n = 62-64 and 8 pairs of macrochromosomes. A distinct feature was a sharp macro-microchromosome boundary. Telomeric

Although young children can sometimes produce words in a near perfect form at a very early stage, several diary studies revealed that these correct first productions are usually followed by less faithful renditions, only to be returned later to relative accuracy. In order to investigate if this nonlinear pattern of children vocal production called “phonological regression” might also be shared with birds, we examined here the trajectory of vocal development of a young African Grey parrot (Athena) who is learning referential English.

Human speech is considered to be unique means of communication. The beginnings of human vocalization, which develops into the speech, however, have some patterns or principles which can also be found in animal communication. It has been discovered that there are similarities between humans and animals in terms of social organization, neural control, cognition and function of vocal signals. Moreover, it seems that birds, parrots specifically, have closer parallels with humans in these respects than with other primates.

Abstract:
Jean-Pierre Bat proceeds to the heart of Franco-African networking after the independences of the former colonies, and evaluates the influence of a particular individual who held a major part of the responsibilities for the scandal-ridden realities of French influence in various African countries during the 1960s and 1970s: Jacques Foccart. Charles de Gaulle’s ‘Mr Africa’ did everything possible to create his own legend, and he was the object of attacks and a source of astonishment in his own ranks. Called “Rasputin” and the “grey eminence – éminence grise - of the General”, amongst other nicknames, it is challenging to carve the role of Foccart out of the legend surrounding him. Essential for an understanding of Foccart’s influence is the analysis of his effective control over France’s African policies, combined with his role in, the intelligence services, from the SAC to the SDECE. Bat’s study will thus give a new account of a system largely dominated by one great player, and investigate Foccart’s impact on the Franco-African networks beyond his time as Secretary for African and Malagasy Affairs.

Abstract:
Africa’s eastern littoral borders the Indian Ocean, providing the setting for the settlements, people, and language known collectively as Swahili, which have been a key part of that ocean’s trading networks for at least two millennia. Graeco-Roman sailors visited the now-forgotten metropolis of Rhapta, and their voyages were recorded in the narratives that later became the first-century Periplus of the Erythraean Sea (Casson 1989). Traces of that early contact survive in the form of beads and coins, yet are limited in number and diffuse in nature (Chami and Msemwa 1997a; Horton 1990). From the seventh century onwards, a series of more permanent settlements began to monopolize this trade; by the eleventh century some of these had grown into towns that were able to control and provide a focus for the mercantile opportunities of the Indian Ocean. The trading economy of Swahili towns was based on the wealth of the African continent—gold and ivory were particularly valuable exports—and underlain by a mixed economy and diverse population of fishers and farmers, traders and craft-workers (Horton and Middleton 2000; Kusimba 2008). By the ‘golden age’ of the thirteenth and fourteenth centuries, the Swahili were an African society of considerable cosmopolitanism and fame, with towns like Kilwa Kisiwani known throughout the medieval world (Sutton 1993, 1997). Swahili archaeology is focused, conceptually and methodologically, on the series of stone towns that grew up along Africa’s eastern coast from the end of the first millennium AD. These towns developed as key nodes in both local and international networks of interaction, and became the conduits through which the African continent traded and communicated with the wider Indian Ocean world. The material settings of the towns, and particularly the distinctive tradition of coral architecture they contain, embody their cosmopolitanism, with this locally derived building tradition creating unique urban spaces that nevertheless reference the Islamic architecture of the Arabian Peninsula and Persian Gulf (Garlake 1966). Archaeology on this coast is still relatively new, dating back only to the 1950s and 1960s, and to the pioneering work of researchers convinced they had discovered evidence for Arab trading stations on the coast of eastern Africa (Kirkman 1964).

Abstract:
This chapter offers a more complex and multiracial view of history by revisiting the narrative of the Japanese American redress movement and discovers a paradox at its core: while the campaign by Japanese Americans for reparations for their wartime confinement started at the end of the 1960s as part of a wider antiracist coalition, and received key support in its early stages from African American political leaders, Japanese Americans increasingly distanced themselves from their black allies as the goal of redress grew nearer, even as African Americans became increasingly public in their opposition. The chapter also shows how the victory of the redress movement in 1988 offered a major precedent, and a model, for reparations efforts by blacks.

The historical period under consideration is roughly the 700 years from 750 CE to 1450 CE, although the earliest mathematical works date from around 825. The chapter first discusses the arithmetic from this period, through the works of Aḥmad ibn al-Bannā, and others.

Abstract:
Dr. Dorothy J. Phillips (Fig. 2.1) is a retired industrial chemist and a member of the Board of Directors of the ACS. Dorothy Jean Wingfield was born in Nashville, Tennessee on July 27, 1945, the third of eight children, five girls and three boys. She was the second girl and is very close to her older sister. Dorothy grew up in a multi- generational home as both her grandmothers often lived with them. Her father, Reverend Robert Cam Wingfield Sr., born in 1905, was a porter at the Greyhound Bus station and went to school in the evenings after he was called to the ministry. He was very active in his church as the superintendent of the Sunday school; he became a pastor after receiving an associate’s degree in theology and pastoral studies from the American Baptist Theological Seminary. Her mother, Rebecca Cooper Wingfield, occasionally did domestic work. On these occasions, Dorothy’s maternal grandmother would take care of the children. Dorothy’s mother was also very active in civic and school activities, attending the local meetings and conferences of the segregated Parent Teachers Association (PTA) called the Negro Parent Teachers Association or Colored PTA. For that reason, she was frequently at the schools to talk with her children’s teachers. She also worked on a social issue with the city to move people out of the dilapidated slum housing near the Capitol. The town built government subsidized housing to relocate people from homes which did not have indoor toilets and electricity. She was also active in her Baptist church as a Mother, or Deaconess, counseling young women, especially about her role as the minister’s wife. When Dorothy went to school in 1951, Nashville schools were segregated and African American children went to the schools in their neighborhoods. But Dorothy’s elementary, junior high, and high schools were segregated even though the family lived in a predominately white neighborhood. This was because around 1956, and after Rosa Park’s bus boycott in Montgomery, AL, her father, like other ministers, became more active in civil rights and one of his actions was to move to a predominately white neighborhood.
