International Negotiation Simulations: An Examination Of Learning Processes And Outcomes

Negotiation skills are valuable tools especially in the international business context. However, the extent to which negotiation simulations build new skills rather than augment existing skills is unclear. This empirical study focuses on the extent to which Mexican students and U.S. students learned from a negotiation simulation. The results indicate that all students learned something but that the Mexican students learned more

Effect of Varied Macronutrient Ratios on Honey Bee Tolerance to IAPV Infection

Honey bees are killed by Israeli acute paralysis virus (IAPV). Because this virus has no cure, it is important to lessen its impact on bees through proper nutrition. This project explores the effects of differing protein to lipid (P:L) ratios in pollen on honey bee susceptibility to this virus. Over three trials, bees in cages were incubated for 3 days to resemble hive conditions. Two doses of IAPV (10-3 & 10-2) and a negative control were used, along with five P:L ratios (1.5, 2.5, 11.5, 16.5, & 21.5:1) and a sucrose-only diet. These treatment groups were combined to create a total of 18 treatments (three doses by six diets). After feeding infected bees diets altered with either casein or canola oil (P or L) mortality was measured every 12 hours. Resulting data found significant differences in mortality rates between diet treatments among bees infected with a 10-2 dose. No significant differences between diets were found in the negative control and 10-3 groups

Developing Better Measures of Neighbourhood Characteristics and Change for Use in Studies of Residential Mobility: A Case Study of Britain in the Early 2000s

This paper addresses the problem of measuring neighbourhood characteristics and change when working with individual level datasets to understand the effects of residential mobility. Currently available measures in Britain are in various respects unsuitable for this purpose. The paper explores a new indicator of small area poverty: the Unadjusted Means-tested Benefits Rate (UMBR), which divides claimants of means-tested benefits in a small area by the number of households. We describe changes in area poverty between 2001 and 2006, using UMBR. As often assumed, these are generally negligible, but small areas in “disadvantaged urban“ and “multicultural city life“ communities did change considerably in this period. We also link UMBR to the first three waves of the UK Millennium Cohort Study, a survey of families with children born at the beginning of the 2000s. We examine opinions about neighbourhood and find that parents living in areas of higher poverty did tend to express more negative views than those living elsewhere. Living in high poverty areas was also associated with moving home, and those families who retrospectively gave neighbourhood considerations as reasons for moving did move into areas with markedly lower poverty rates. Finally, we compare families' moving trajectories to trends in poverty within areas. We are able to show that a large proportion of families who moved to poorer neighbourhoods were at double disadvantage, as they often moved to areas with increasing poverty rates. We conclude that UMBR can be used to enhance understanding of changing neighbourhood contexts in cohort studies, at least for this period, although it still suffers from the same conceptual and technical difficulties as other available alternatives in terms of its ability to capture aspects of neighbourhood quality

Operative and Radiographic Acetabular Component Orientation in Total Hip Replacement: Influence of Pelvic Orientation and Surgical Positioning Technique

Orthopaedic surgeons often experience a mismatch between perceived intra-operative and radiographic acetabular cup orientation. This research aimed to assess the impact of pelvic orientation and surgical positioning technique on operative and radiographic cup orientation. Radiographic orientations for two surgical approaches were computationally simulated: a mechanical alignment guide and a transverse acetabular ligament approach, both in combination with different pelvic orientations. Positional errors were defined as the difference between the target radiographic orientation and that achieved. The transverse acetabular ligament method demonstrated smaller positional errors for radiographic version; 4.0° ± 2.9° as compared to 9.4° ± 7.3° for the mechanical alignment guide method. However, both methods resulted in similar errors in radiographic inclination. Multiple regression analysis showed that intraoperative pelvic rotation about the anterior-posterior axis was a strong predictor for these errors (B TAL = −0.893, B MAG = −0.951, p &lt; 0.01). Application of the transverse acetabular ligament method can reduce errors in radiographic version. However, if the orthopaedic surgeon is referencing off the theatre floor to control inclination when operating in lateral decubitus, this is only reliable if the pelvic sagittal plane is horizontal. There is currently no readily available method for ensuring that this is the case during total hip replacement surgery. </p
