Communication and Conversion in Northern Cameroon: The Dii by Tomas Sundnes Dronen
By Tomas Sundnes Dronen
Used to be sleek Christian project to Africa essentially a colonial undertaking and a civilizing challenge or used to be it a religious revival spreading to new components? This booklet tells the story of the Dii humans in northern Cameroon and describes their come upon with Norwegian missionaries. via archival stories and during fieldwork one of the Dii, an exciting situation is gifted. while the missionaries describe their venture as one among religious liberation, and the Dii highligt the social liberation they got via literacy and political independence, the writer indicates how either non secular and social alterations have been result of captivation, miscommunication and relentless negotiations among the 2 events.
The Postal Age: The Emergence of Modern Communications in by David M. Henkin
By David M. Henkin
Americans in general realize tv, e mail, and quick messaging as brokers of pervasive cultural switch. yet many people won't become aware of that what we now name snail mail was simply as innovative. As David M. Henkin argues in The Postal Age, a burgeoning postal community initiated significant cultural shifts through the 19th century, laying the basis for the interconnectedness that now defines our ever-evolving international of telecommunications. This interesting historical past lines those shifts from their beginnings within the mid-1800s, while more cost-effective postage, mass literacy, and migration mixed to make the common postal carrier a extra essential and potential a part of way of life. With such dramatic occasions because the Civil conflict and the gold rush underscoring the significance and necessity of the submit, an incredibly large diversity of Americans—male and feminine, black and white, native-born and immigrant—joined this postal community, frequently interacting with far-off locales earlier than the lifestyles of phones or perhaps the frequent use of telegraphy. Drawing on unique letters and diaries from the interval, in addition to public discussions of the increasing postal method, Henkin tells the tale of the way those american citizens adjusted to a brand new global of long-distance correspondence, crowded submit places of work, direct mail, valentines, and useless letters. The Postal Age paints a colourful photo of a society the place percentages proliferated for the types of non-public and impersonal communications that we regularly go together with newer historic sessions. In doing so, it considerably raises our figuring out of either antebellum the US and our personal bankruptcy within the historical past of communications.
