Internatonal trade relies on buyers and sellers sharing and successfully executng various costly and ofen unpredictable logistcal tasks. Existng work on the obstacles to smooth delivery summarizes the physical and insttutonal diferences between origin and destnaton countries as some form of “fricton” that impedes aggregate trade fows. I ofer the frst breakdown of the delivery process into its v...

Studies based on British Crime Survey (BCS) data suggest that the overall incidence of workplace assault is relatively low. However, these data have a number of limitations. They include only assaults carried out by clients or the public, provide limited information about the individuals involved and their workplaces, and tell us little about perceived causes of violence at work. The 2008 Workp...

W characterize the equilibrium behavior in a broad class of competition models in which the competing firms’ market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm’s revenues and costs are proportional with its expected sales volume, with a cost rate that depends on the firm’s ch...

The finding of other investigators that increased water content is often associated with signs of a torn collagen network in human osteoarthritic (OA) cartilage led to this study. In the Pond-Nuki model of post-traumatic OA experimental but not control femoral condylar cartilage showed evidence of breakdown and stiffening of collagen network as assessed by measurement of swelling properties and...

This paper aims to find errors that lead to dialogue breakdowns in chat-oriented dialogue systems. We collected chat dialogue data, annotated them with dialogue breakdown labels, and collected comments describing the error that led to the breakdown. By mining the comments, we first identified error types. Then, we calculated the correlation between an error type and the degree of dialogue break...

there exists an arrangement in 5 in which a* follows all the Oi with i<k. Such sets Ssurely exist; for example, any set of m arrangements whose terminal elements are 1, 2, • • • , m, respectively, will obviously be ^-suitable for any k^m. The smallest cardinal number N such that there exists a set of N arrangements which is ^-suitable for m will be denoted by N(m, k); this is therefore a well d...

This paper evaluates the influence of water content and mixing conditions (mixing time sequence addition constituents) on fresh state properties lime-based materials their impact hardened properties. Higher contents allowed an increased fluidity lower torque, yield stress plastic viscosity values. In turn, a longer with aggregate caused progressively stiffer mortar substantial increase in value...

The effects of heat-induced denaturation and subsequent aggregation of whey protein isolate (WPI) solutions on the rate of enzymatic hydrolysis was investigated. Both heated (60 °C, 15 min; 65 °C, 5 and 15 min; 70 °C, 5 and 15 min, 75 °C, 5 and 15 min; 80 °C, 10 min) and unheated WPI solutions (100 g L(-1) protein) were incubated with a commercial proteolytic enzyme preparation, Corolase PP, un...

We present experimental observations and a conceptual model for understanding the compression swelling characteristics of Old Alluvium (OA) from San Juan, Puerto Rico. Prior studies have classified OA as transported, in situ weathered tropical soil whose intact macrostructure comprises cemented, pseudo-silt with mixture quartz grains aggregated clay particles. The aggregates include mixtures ka...
