A 68 year old female who had occult instability at a symptomatic osteoporotic L1 burst fracture was diagnosed by manual axially loaded magnetic resonance imaging. Traction resulted in the reduction of the fracture and decompression of the conus. Based on these findings, the patient underwent L1-L2 fusion with complete resolution of her back and leg pain. Our objective is to describe the utility...

1. A back-to-back cargo movement is generally understood as the transfer of loose goods from one truck to another---in its literal form, positioning two trucks with their backs to one another. Primitive variants involve laborintensive handling and placement of cargo on the ground during the transfer. This process inflicts serious time delays and damage to cargo and is widely avoided in modern t...

Industry revenue for online games is surging. A unique phenomenon in this market is the significant volume of trade among game users, who exchange real money for virtual goods that do not exist in the real world. The market of virtual goods has two distinctive characteristics: 1) the resold virtual items normally involve no quality loss since the attributes are digitally defined, and 2) the gam...

We study the problem of allocating a set of indivisible items to players having additive utility functions over the items. We consider allocations in which no player envies the bundle of items allocated to the other players too much. We present a simple proof that deterministic truthful allocations do not minimize envy by characterizing the truthful mechanisms for two players and two items. Als...

In this account of the history of voting-power measurement, we confine ourselves to the concept of a priori voting power. We show how the concept was re-invented several times and how the circumstances in which it was reinvented led to conceptual confusion as to the true meaning of what is being measured. In particular, power-as-influence was conflated with value in the sense of transferable ut...

Real annual consumption growth has averaged about 3.7% between 1998 Q1 and 2003 Q3—well above real average annual GDP growth of about 2.6% during that period. (2) Chart 1 shows that the buoyancy of consumer spending can be entirely accounted for by strong growth in durable and semi-durable goods expenditure (henceforth referred to as 'durable spending' unless otherwise specified). Since 1998 Q1...

BACKGROUND A combination of frontal bending, lateral bending, and torsion in the loaded trunk has been suggested to be a mechanism leading to overuse injuries of the back in Alpine ski racing. However, there is limited knowledge about the effect of course setting on the aforementioned back-loading patterns. PURPOSE To investigate the effect of increased gate offset on the skier's overall trun...

Over the course of the twentieth century, the availability of cheap, mass-produced fashion has contributed to a decline in everyday domestic mending skills. Indeed, as mass-manufactured goods have become cheaper for the global population it has become normative consumer behaviour to dispose of any item that is less than perfect, even when the damage is entirely superficial, leading Clark to cla...
