Review of 'Pictures Bring Us Messages' / Sinaakssiiksi aohtsimaahpihkookiyaawa: Photographs and Histories from the Kainai Nation by Alison K. Brown and Laura Peers with members of the Kainai Nation

In August 1925, University of Oxford anthropologist Beatrice Blackwood spent two days on the Blood Reserve in southern Alberta, home to the Kainai Nation. Assisted by the Indian Agent, she toured the reserve and took 33 photographs. Blackwood was investigating potential links among "race," culture, and environment, and some of her photographs were anthropometric in nature. Others, showing men working in fields or girls at residential school, portrayed a culture in transition. Upon her return to Britain, Blackwood deposited the Kainai photographs with Oxford's Pitt Rivers Museum.

Priority-based Lambda Scheduler

Optical networks provide a new dimension to meet the demands of exponentially growing traffic. Optical packet switching requires a good switch architecture, which eliminates the O/E/O conversion as much as possible. Wavelength Division Multiplexing (WDM) provides a breakthrough to exploit the huge bandwidth of the optical fiber. Different applications have different requirements, which necessitate employing differentiated services. This paper presents the idea of a priority-based λ-scheduler, where the packets are differentiated into different classes and services are provided accordingly. For example, class 0 can correspond to non real time applications like email and ftp, while class 1 can correspond to real-time audio and video communications. The architecture is based on that of the λ-scheduler and hence it has the added advantage of reduced component cost by using WDM internally.
