A serological survey was conducted among Tuareg nomads to determine their level of immunity to measles. More than half (57.9%) of the children under 10 years of age did not have detectable antibodies to measles, suggesting that transmission of the disease is low in this mobile population. Mothers' reports of their children's history of measles were accurate (positive predictive value 93.9% for ...

NOMADS is a mobile agent system that supports strong mobility (i.e., the ability to capture and transfer the full execution state of mobile agents) and safe Java agent execution (i.e., the ability to control resources consumed by agents, facilitating guarantees of quality of service while protecting against denial of service attacks). The NOMADS environment is composed of two parts: an agent ex...

The incidence of infections was studied in 137 iron-deficient Somali nomads, 67 of whom were treated with placebo and 71 with iron. Seven episodes of infection occurred in the placebo group and 36 in the group treated with iron; these 36 episodes included activation of pre-existing malaria, brucellosis, and tuberculosis. This difference suggested that host defence against these infections was b...

The pastoral nomads of Iran, who had been able to achieve a “sustainable balance” between their environment and their economy throughout their history, are being held responsible for the degradation of the rangelands by the experts and state officials. The government of Iran has placed considerable resources into provision of advice and services to improve the natural resource status of Iranian...

This contribution looks at the influence of technological change that nomads in the Russian North have undergone, using as examples two crucial innovations: the snowmobile and the mobile phone. I argue that the snowmobile did not have the same revolutionary impact on the Russian tundra as it did in Fennoscandia, for reasons connected to long distances, infrastructure, spare parts, availability ...

In my editorial I explicitly and repeatedly refer to “swordfish or tuna from overfished and declining stocks” and to “Mediterranean swordfish.” Even the ICCAT report Kerstetter cites suggests that the Mediterranean swordfish stock is in crisis. So what is the point of criticizing my editorial on the basis that another swordfish stock can be “proudly” eaten because, in Kerstetter’s words, it has...

In complex distributed environments, it is important to achieve high degree of machine-to-machine interaction, not only on a functional, but on a semantic level. Therefore, we propose the NOMADS (Networks of Mobile Adaptive Dependable Systems) Republic, a vision of the future community open to all interested hardware and software entities, and based on adaptive and, if necessary, composable ser...

BACKGROUND Pastoral social-ecological systems (SESs) are adaptive and complex systems rooted in the extensive exploitation of forage plants for livestock-based livelihoods and culture. There are species and relations that are foundational to the existence of these SESs. Nucularia perrinii Batt. (Chenopodiaceae) is an endemic halophyte plant of central and western Sahara seldom cited in the scie...

Sudan has high maternal mortality. The rate among nomads groups of people who move from place to place as a way of obtaining food, finding pasture or make a living is very high and varies between different regions of the country. The objective of the study is to identify the factors affecting the utilization of maternal health care services by nomadic communities in Sudan, to make recommendatio...

The paper describes the goal and practice of the nomadic exhibition guide Hippie. Hippie takes into account the context of use of the nomadic system. An information system is said to be nomadic when the user has access to both his or her personal information space and to the public information space from all places independent from specific devices—for nomadic systems see (Kleinrock 1997). For ...
