Practical Dynamic Grammars for Dynamic Languages

Grammars for programming languages are traditionally specified statically. They are hard to compose and reuse due to ambiguities that inevitably arise. PetitParser combines ideas from scannerless parsing, parser combinators, parsing expression grammars and packrat parsers to model grammars and parsers as objects that can be reconfigured dynamically. Through examples and benchmarks we demonstrate that dynamic grammars are not only flexible but highly practical.

Cortical control of facial expression.

The present topical review deals with the motor control of facial expressions in humans. Facial expressions are a central part of human communication. Emotional face expressions have a crucial role in human non-verbal behavior, allowing a rapid transfer of information between individuals. Facial expressions can be both voluntarily or emotionally controlled. Recent studies in non-human primates and humans revealed that the motor control of facial expressions has a distributed neural representation. At least 5 cortical regions on the medial and lateral aspects of each hemisphere are involved: the primary motor cortex, the ventral lateral premotor cortex, the supplementary motor area on the medial wall, and, finally, the rostral and caudal cingulate cortex. The results of studies in humans and non-human primates suggest that the innervation of the face is bilaterally controlled for the upper part, and mainly contralaterally controlled for the lower part. Furthermore, the primary motor cortex, the ventral lateral premotor cortex, and the supplementary motor area are essential for the voluntary control of facial expressions. In contrast, the cingulate cortical areas are important for emotional expression, since they receive input from different structures of the limbic system. This article is protected by copyright.

Human rights and international trade

Economic globalization and respect for human rights are both highly topical issues. In theory, more trade should increase economic welfare and protection of human rights should ensure individual dignity. Both fields of law protect certain freedoms: economic development should lead to higher human rights standards, and UN embargoes are used to secure compliance with human rights agreements. However the interaction between trade liberalisation and human rights protection is complex, and recently, tension has arisen between these two areas. Do WTO obligations covering intellectual property prevent governments from implementing their human rights obligations, including rights to food or health? Is it fair to accord the benefits of trade subject to a clean human rights record? This book first examines the theoretical framework of the interaction between the disciplines of international trade law and human rights. It builds upon the well-known debate between Professor Ernst-Ulrich Petersmann, who construes trade obligations as human rights, and Professor Philip Alston, who warns of a merger and acquisition of human rights by trade law. From this starting point, further chapters explore the differing legal matrices of the two fields and examine how cooperation between them might be improved, both in international law-making and institutions,in dispute settlement. The interaction between trade and human rights is then explored through seven case studies:freedom of expression and competition law; IP protection and health; agricultural trade and the right to food; trade restrictions on conflict WHO convention on tobacco control; and, finally, human rights conditionalities in preferential trade schemes.
