Subway Sound to be Upgraded

BOSTON (April 1)-The public address systems at selected subway stations are scheduled to be refurbished, the Transit Authority announced this week. The systems are used to make announcements to commuters both on the platforms and in the stations.

Local commuters welcomed the news, although for some it was long overdue.

"It can be pretty difficult to understand the announcements at some of the stations I use most frequently," said Ian Miller, who has taken the subway to work nearly every week for the past eighteen years. "I had heard the reports about it on TV, and all I can say is that it is about time!"

Some of the systems currently in use are more than 30 years old. Worn-out speakers, wiring, microphones, and amplifiers will be replaced with new, more reliable devices. The work should be completed in October and cost more than $11 million.

Boston's subway system came together in stages over the course of several years. The foundational component of the system's Green Line first opened on Tremont Street in the late 1890s. It was the first of its kind in the United States.

E-Commerce Opening Doors for African Fashion Industry

ADDIS ABABA (6 May) - Africa's role as a consumer of fashion has been on the rise in recent years. This trend is largely due to the emergence of e-commerce, which provides Africans the opportunity to buy clothing from retailers with no physical presence on the continent.

Perhaps more importantly, though, the growth of e-commerce is enabling small-scale African designers to also become producers of fashion, as they showcase their collections to consumers worldwide. African shopping Web sites like Jumjum and Longa are making the work of African designers available for purchase not just throughout the continent, but also as far away as London and New York. - [1] - .

"African designers are finally gaining visibility," says Mazaa Absher, founder of Abbi Sportscore, Afri ca's fastest-growing athletic footwear company. "We have always had terrific design and production capacity here on the continent, but it was hard getting it out into the world. Now we are generating more sales online than we are in our stores."

Even as Ms. Absher has transformed her company into an international powerhouse, she continues to highlight the advantages of manufacturing its products in her home city of Nazret. - [3] - . Africa's strong textile sector and innovative designs combine tradition and wearability, and this formula is allowing companies like hers to set their sights beyond the continent. "As more cities in Ethiopi a-and all over Africa- improve their manufacturing capacity, it will become easier to reach the rest of the world," says Ms. Absher. - [4] - .
