This paper investigates the determinants of regional specialization between 1992 and 1997 using a panel covering 33 industries across 25 Chinese regions, paying particular attention to the role of regional protectionism. This study is motivated by a double paradox concerning the Chinese economy over the reforms. First some authors evidence reduced regional specialization despite the promotion of liberalization away from

Abstract Syntax/semantics interfaces using unification-based or feature-based formalisms are increasingly common in the existing computational linguistics literature.

In this paper we present BurstProbe, a new technique to accurately measure link burstiness in a wireless sensor network employed for time-critical data delivery. Measurement relies on shared probing slots that are embedded in the transmission schedule and used by nodes to assess link burstiness over time. The acquired link burstiness information can be stored in the node's ash memory and relied upon to diagnose transmission problems when missed deadlines occur. Thus, accurate diagnosis is achieved in a distributed manner and without the overhead of transmitting rich measurement data to a central collection point. For the purpose of evaluation we have implemented BurstProbe in the GinMAC WSN protocol and we are able to demonstrate it is an accurate tool to debug time-critical data delivery. In addition, we analyze the cost of implementing BurstProbe and investigate its eectiveness.

Rhizosphere engineering is a cutting-edge biotechnological approach, strategically employing microbial biofertilizers, phytostimulants, and plant growth promoting rhizobacteria (PGPR) to boost agricultural crop productivity. Unlike conventional chemical fertilizers, this method eliminates harmful substances, mitigating environmental and health concerns. The foundation of rhizosphere engineering lies in the intricate study of plant–microbe interactions, where soil microorganisms play a pivotal role in nutrient cycling, agricultural waste decomposition, and plant growth stimulation. Rhizosphere engineering shows immense promise in the semiarid tropics, covering around 26% of the Earth's ecology and characterized by water scarcity and high temperatures. Microorganisms found in the rhizosphere, endosphere, and vegetation of arid plants have adapted to harsh environmental conditions, offering valuable resources for biofertilizer and biocontrol research. Their application in enhancing water and nutrient absorption can help alleviate water stress, contributing to sustainable crop production in these regions. However, fully realizing the potential of rhizosphere engineering presents numerous challenges. Identifying beneficial microorganisms, establishing standardized protocols, comprehending complex plant–microbe–soil interactions, and developing efficient delivery systems for microbial inoculants are among the bottlenecks that must be addressed. These challenges underscore the need for continuous research and innovation in this field. Despite being in its infancy, rhizosphere engineering has already accumulated a wealth of information and insights. By surmounting existing challenges and harnessing the power of PGPR and other rhizosphere microorganisms, rhizosphere engineering may usher in a new era in agriculture, particularly benefiting the water-stressed regions of the semiarid tropics.
