Adjustment disorder is not a new diagnostic category. It was incorporated into DSM-III in 1980 (American Psychiatric Association 1980) and into ICD-9 in 1978 (World Health Organization 1978), having been called transient situational dis turbance in earlier editions. It represents a maladaptive but temporary reaction to life stressors. There are no detailed diagnostic criteria in either DSM-IV-T...

In this paper, we propose to replace Scheme rst class continuations by a sequential thread system. Our threads are very close to continuations but they are easier to understand and to use for programmers, and its implementation is simpler and more eecient. We show that with our threads we can recover almost completely the Scheme operator call-with-current-continuation (call/cc for short). The o...

Intermediate network elements, such as network address translators (NATs), firewalls, and transparent caches are now commonplace. The usual reaction in the network architecture community to these so-called middleboxes is a combination of scorn (because they violate important architectural principles) and dismay (because these violations make the Internet less flexible). While we acknowledge the...

In addition to linguistically coded information, speech conveys necessarily also some paralinguistic information of expressive (affective and adaptive), organic and perspectival kind, but all respective features lack invariant absolute acoustic correlates. According to the Modulation Theory, a speaker’s voice functions as a carrier that is modulated by speech gestures. Listeners have to demodul...

Many synchronizations in existing multi-threaded programs are implemented in an ad hoc way. The first part of this paper does a comprehensive characteristic study of ad hoc synchronizations in concurrent programs. By studying 229 ad hoc synchronizations in 12 programs of various types (server, desktop and scientific), including Apache, MySQL, Mozilla, etc., we find several interesting and perha...

Deduplication is widely used to improve space efficiency in storage systems. While much attention has been paid to making the process of deduplication fast and scalable, the effectiveness of deduplication can vary dramatically depending on the data stored. We show that many file formats suffer from a fundamental design property that is incompatible with deduplication: they intersperse metadata ...

Hume presents two definitions of cause in his Enquiry which correspond to his two definitions in his Treatise. The first of the definitions is ontological and the second is psychological; indeed, the definitions are extensionally and intensionally distinct. The critical mistake of the skeptical interpretation is the assumption that the two definitions are equivalent, and the critical mistake of...

As more countries adopt laws and regulations concerning euthanasia, pediatric euthanasia has become an important topic of discussion. Conceptions of what constitutes harm to patients are fluid and highly dependent on a myriad of factors including, but not limited to, health care ethics, family values, and cultural context. Euthanasia could be viewed as iatrogenic insofar as it results in an out...

Planning research has returned to the issue of optimizing costs (rather than sizes) of plans. A prevalent perception, at least among non-experts in search, is that graph search for optimizing the size of paths generalizes more or less trivially to optimizing the cost of paths. While this kind of generalization is usually straightforward for graph theorems, graph algorithms are a different story...

Optimistic concurrency relies on speculative execution, read-write conflict detection, and checkpointrollback techniques to provide a programming model that replaces locks with the abstraction of atomic, isolated execution of critical sections. Previous research has shown that on chip multi-processors, a class of workloads featuring irregular parallelism and rare read-write conflicts can reap s...
