The 'Masai' and miraa: public authority, vigilance and criminality in a Ugandan border town

Recent studies on vigilante groups show how they often begin as popular schemes for imposing order, before degenerating into violent militias which contribute in turn to social and political disorder. The Masai, a group of khat sellers and consumers in the Ugandan border town of Bwera, represent a more complex case. By using vigilance tactics in the provision of security, the Masai actually help to shape public authority within Bwera town instead of creating institutional chaos. They also provide a range of services, imposing a degree of order on illegal cross-border activities in the area. However, a closer look at the Masai shows that their vigilance activities are mainly performed out of self-interest, as a quid pro quo enabling them to continue their illegal activities of smuggling, general criminality outside town and illegal drug use. Therefore they straddle the 'crime or social order' dynamic, representing a criminal gang of illegal drug traffickers which also provides services for public community interests. As such, they contribute to both order and crime

Strategic Public Housing and Foreign Direct Investment

We suggest that public housing matters for FDI. We assume that FDI creates gains for some residents and losses for others. Losers from FDI will oppose FDI. To win support for FDI, local government may want to pay compensation in cash. In the paper’s model, however, cash payments are not successful. But public housing is. – Ultimately we argue that (1) public housing makes FDI more palatable where (2) cash transfers fail, so that (3) local government may choose to invest into public housing to overcome opposition against FDI.Public Housing, Foreign Direct Investment

Muscle-Specific Effective Mechanical Advantage and Joint Impulse in Weightlifting

Lifting greater loads during weightlifting exercises may theoretically be achieved through increasing the magnitudes of net joint impulses or manipulating the joints’ effective mechanical advantage (EMA). The purpose of this study was to investigate muscle-specific EMA and joint impulse as well as impulse-momentum characteristics of the lifter-barbell system across a range of external loads during the execution of the clean. Collegiate-level weightlifters performed submaximal cleans at 65, 75, and 85% of their 1-repetition maximum (1-RM) while data from a motion analysis system and a force plate were used to calculate lifter-barbell system impulse and velocity, as well as net extensor impulse generated at the hip, knee, and ankle joints and the EMA of the gluteus maximus, hamstrings, quadriceps, and triceps surae muscles. The results indicated that the lifter-barbell system impulse did not change as load increased, whereas the velocity of the lifter-barbell system decreased with greater load. In addition, the net extensor impulse at all joints increased as load increased. The EMA of all muscles did not, however, change as load increased. The load-dependent effects on the impulse-velocity characteristics of the lifter-barbell system may reflect musculoskeletal force-velocity behaviors, and may further indicate that the weightlifting performance is limited by the magnitude of ground reaction force impulse. In turn, the load-dependent effects observed at the joint-level indicated that lifting greater loads were due to greater net extensor impulses generated at the joints of the lower extremity and not greater EMAs of the respective extensor muscles. In combination, these results suggest that lifting greater external loads during the clean is due to the ability to generate large extensor joint impulses, rather than manipulate EMA
