The Curvilinear Effects of Extroversion on Subjective and Objective Sales Outcomes

Recent advances in the shape of the extraversion-sales performance relationship suggests being highly introverted and highly extraverted can be detrimental to customer interactions. Using two archival data sets (Study 1: N = 574, Study 2: N = 168), the current study explored non-linear extraversion-sales performance relationships at both the factor- and facet-level for predicting objective and subjective criteria. Findings suggest significant non-linear relationships for extraversión facets with specific criteria combinations. Sales organizations should consider facets over factors for performance prediction. Implications for hiring extraverted sales professionals are discussed

Metaphyseal sclerosis in patients with chronic renal failure

We reviewed radiographs of the hands and wrists of 33 patients with immature skeletons and chronic renal disease. Various radiographic manifestations of renal osteodystrophy were seen, including osteopenia in 23 patients (70%), subperiosteal resorption in 20 (61%), distal tuft resorption in 14 (42%), sclerosis of vertebral bodies in 2 (6%), and soft-tissue calcification in 1 (3%). We also noted that 13 patients (39%) exhibited metaphyseal sclerosis adjacent to the growth plates. Five of these 13 showed persistent sclerosis years after the growth plates had fused. None of the patients showed other radiographic changes of rickets, and there was no correlation between the serum calcium, phosphorus, or aluminum levels and the presence of metaphyseal sclerosis. Neither was there any association with the underlying cause of renal failure, method of treatment, presence of a transplant, or type of dialysis. We view this finding as another manifestation of renal osteodystrophy. The importance of distinguishing it from other sclerotic lesions is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46802/1/256_2004_Article_BF00241668.pd

Competition to identify key challenges for unmanned aerial robots in near earth environments

IEEE International Conference on Advanced Robotics, Seattle, WA, pp. 303-308, July 2005. Retrieved April 2006 from http://prism2.mem.drexel.edu/~paul/papers/greenIcar2005.pdfTasks like bomb-detection, search-and-rescue, and reconnaissance in near-Earth environments are time, cost and labor intensive. Aerial robots could assist in such missions and offset the demand in resources and personnel. However, flying in environments rich with obstacles presents many more challenges which have yet to be identified. For example, telephone wire is one obstacle that is known to be hard to detect in mid-flight. This paper describes a safe and easy to fly platform in conjunction with an aerial robot competition to highlight key challenges when flying in near- Earth environments

Do Cost-Based Pricing Biases Persist in Laboratory Markets?

Past accounting experiments have demonstrated significant effects of absorption vs variable costing systems on pricing decisions, but in individual settings that suppressed market features. The main finding of the current study is that a cost-based pricing bias did not persist in laboratory product markets. Given the opportunity to learn from profit and market feedback, sellers revised their price offers toward optimum in a manner that compensated for absorption vs variable cost signals. The effects of demand conditions, as revealed through actual trades, dominated the effects of alternative costing systems

Exploring search-and-rescue in nearearth environments for aerial robots

Homeland security missions executed in near-Earth environments are often time consuming, labor intensive and possibly dangerous. Aerial robots performing tasks such as bomb detection, search-and-rescue and reconnaissance could be used to conserve resources and minimize risk to personnel. Flying in environments which are heavily populated with obstacles yields many challenges. Little data exists to guide the design of vehicles and sensor suites operating in these environments. This paper explores the challenges encountered implementing several different sensing technolgies in near-Earth environments. The results of applying these technologies to control a robotic blimp are presented to direct future work.

Spontaneous symbol acquisition and communicative use by pygmy chimpanzees (pan paniscus

Two pygmy champanzees (Pan paniscus) have spontaneously begun to use symbols to communicate with people. In contrast to common chimpanzees (Pan troglodytes) using the same communicative system, the pygmy chimpanzees did not need explicit training in order to form referential symbolobject associations. Instead, they acquired symbols by observing others use these symbols in daily communications with them. In addition, the pygmy chimpanzees have begun to comprehend spoken English words and can readily identify lexigrams upon hearing the spoken words. By contrast, common chimpanzees who received similar exposure to spoken English are unable to do so. The older pygmy chimpanzee has begun to form requests of the form agent-verb-recipient in which he is neither the agent nor the recipient. By contrast, similarly aged common chimpanzees limited their requests to simple verbs, in wihch the agent was always presumed to be the addressee and the chimpanzee itself was always the recipient, thus they had no need to indicate a specific agent or recipient. These results suggest that these pygmy chimpanzees exhibit symbolic and auditory perceptual skills that are distinctly different from those of common chimpanzees. What's in a Name?
