This paper presents a study of successive new product introductions in the mature tennis racket industry. The inquiry examines novel design’s important role in strategic renewal, under the assumption that innovation includes not only the development, production, and launch of new products, but also communication between firms and market. We explore this industry’s transformation through the str...

The purpose of the study was to identify the relationships between segmental angular momentum and ball velocity between the following events: ball toss, maximal elbow flexion (MEF), racket lowest point (RLP), maximal shoulder external rotation (MER), and ball impact (BI). Ten tennis players performed serves recorded with a real-time motion capture. Mean angular momentums of the trunk, upper arm...

In recent years, it has been encouraging to watch the developmental non-governmental organizations (NGOs) become more sophisticated in their thinking on the benefits of trade liberalization. NGOs such as Public Citizen that are against all forms of liberalization are now rare.

Many studies using cognitive tasks have found that stereotype threat, or concern about confirming a negative stereotype about one's group, debilitates performance. The few studies that documented similar effects on sensorimotor performance have used only relatively coarse measures to quantify performance. This study tested the effect of stereotype threat on a rhythmic ball bouncing task, where ...

Research activities aimed to understand the dynamics of criminal networks or organisations – like extortion racket systems – are of interest for criminologists and scientists in related fields, for practitioners from police and judiciary, as well as for political decision makers. This paper aims to contribute to this area by bringing together data analysis methods with conceptual modelling and ...
