In this paper, we study the estimation problems for the two-parameter exponentiated Gumbel distribution based on lower record values. An exact confidence interval and an exact joint confidence region for the parameters are constructed. A simulation study is conducted to study the performance of the proposed confidence interval and region. Finally, a numerical example with real data set is gi...

This journal promised 6 years ago to publish studies on what it termed “CSCL and its flash themes” (Stahl 2007). Rather than devoting single issues to specific topics of timely prominence, we decided to welcome submissions about selected emerging themes of CSCL research on an on-going basis. Accordingly, we set aflame again in the current issue discussion of the topics of argumentation, scripti...

Many sensorimotor neurons in the CNS encode global parameters of limb movement and posture rather than specific muscle or joint parameters. Our investigations of spinocerebellar activity have demonstrated that these second-order spinal neurons also may encode proprioceptive information in a limb-based rather than joint-based reference frame. However, our finding that each foot position was dete...

A force capacity evaluation for a given posture may provide better understanding of human motor abilities applications in sport sciences, rehabilitation and ergonomics. From data on maximum isometric joint torques, the upper-limb feasible set hand was predicted by four models called ellipsoid, scaled polytope polytope, which were compared with measured polytope. The volume, shape prediction err...

The marketing performance of international joint ventures (IJVs) particularly of those in the Southeast Asian Economies has not received adequate attention from international business researchers and International Joint Ventures (IJVs) have become an important means of market entry for many firms, particularly those seeking entry into Asia. This study identifies the factors influencing the mark...

We study the problem of the joint location of seismic events using an array of receivers. We show that locating multiple seismic events simultaneously is advantageous compared to the more traditional approaches of locating each event independently. Joint location, by design, includes estimating an uncertainty distribution on the absolute position of the events. From this can be deduced the dist...

Using subject indexes and text mining of author abstracts, the authors track the evolution of content in Journal of Marketing Research since its inception 50 years ago. These data reveal that the journal has expanded beyond its initial emphasis on marketing research methods and advertising to increase its coverage of other substantive topics and consumer behavior. Moreover, a joint space of top...

Emotion expression in human-human interaction takes place via various types of information, including body motion. Research on the perceptual-cognitive mechanisms underlying the processing of natural emotional body language can benefit greatly from datasets of natural emotional body expressions that facilitate stimulus manipulation and analysis. The existing databases have so far focused on few...

This study investigates preparatory rotation as a manipulation strategy for grasping objects from different presented orientations. Participants lifted heavy, handled objects from eight initial orientations under two task constraints. When object motion was permitted, participants used preparatory rotation to first adjust the object handle to a desired orientation before lifting. The amount of ...
