Review of Comprendre et soigner la crise suicidaire.

Reviews the book, Comprendre et soigner la crise suicidaire by Laurent Morasz et Fran?ois Danet (2008).This work examines a psychodynamic theoretical approach focused on the suicide crisis clinic and the “caregiver/cared for” relationship by illustrating different clinical examples representing individuals at various stages of the suicide process. The value and strength of this book lie in the rich and interesting clinical experience it brings forward; there is no attempt to distinguish between “objective” and “more subjective psychodynamic” approaches.

How to hit scylla without avoiding charybdis: Comment on Perruchet, Tyler, Galland, and Peereman (2004).

M. Pe?a, L. L. Bonatti, M. Nespor, and J. Mehler (see record 2002-06215-001) argued that humans compute nonadjacent statistical relations among syllables in a continuous artificial speech stream to extract words, but they use other computations to determine the structural properties of words. Instead, when participants are familiarized with a segmented stream, structural generalizations about words are quickly established. P. Perruchet, M. D. Tyler, N. Galland, and R. Peereman (see record 2004-21166-008) criticized M. Pe?a et al.'s work and dismissed their results. In this article, the authors show that P. Perruchet et al.'s criticisms are groundless.

Correction to Perruchet et al. (2006).

Reports an error in "Do We Need Algebraic-Like Computations? A Reply to Bonatti, Pena, Nespor, and Mehler (2004)" by Pierre Perruchet, Ronald Peereman, and Michael D. Tyler (Journal of Experimental Psychology: General, 2006[May], 135(2), 322-326). The page numbers that Dr. Perruchet cited from Dr. Bonatti et al.'s article were printed incorrectly. These page numbers should appear as follows in the correction. (The following abstract of this article originally appeared in record 2006-06642-011.) L. L. Bonatti, M. Pena, M. Nespor, and J. Mehler (see record 2006-06642-010) argued that P. Perruchet, M. D. Tyler, N. Galland, and R. Peereman (see record 2004-21166-008) confused the notions of segmentation and generalization by ignoring the evidence for generalization in M. Pena, L. L. Bonatti, M. Nespor, and J. Mehler (see record 2002-06215-001). In this reply, the authors reformulate and complement their initial arguments, showing that their way of dealing with segmentation and generalization is not due to confusion or ignorance but rather to the fact that the tests used in Pena et al. make it likely that neither segmentation nor generalization were captured in their experiments. Finally, the authors address the challenge posed by Pena et al. of accounting for the whole pattern of their results without invoking rule-based, algebraic-like computations.

Concurrent software verification with states, events, and deadlocks

We present a framework for model checking concurrent software systems which incorporates both states and events. Contrary to other state/event approaches, our work also integrates two powerful verification techniques, counterexample-guided abstraction refinement and compositional reasoning. Our specification language is a state/event extension of linear temporal logic, and allows us to express many properties of software in a concise and intuitive manner. We show how standard automata-theoretic LTL model checking algorithms can be ported to our framework at no extra cost, enabling us to directly benefit from the large body of research on efficient LTL verification. We also present an algorithm to detect deadlocks in concurrent message-passing programs. Deadlock- freedom is not only an important and desirable property in its own right, but is also a prerequisite for the soundness of our model checking algorithm. Even though deadlock is inherently non-compositional and is not preserved by classical abstractions, our iterative algorithm employs both (non-standard) abstractions and compositional reasoning to alleviate the state-space explosion problem. The resulting framework differs in key respects from other instances of the counterexample-guided abstraction refinement paradigm found in the literature. We have implemented this work in the magic verification tool for concurrent C programs and performed tests on a broad set of benchmarks. Our experiments show that this new approach not only eases the writing of specifications, but also yields important gains both in space and in time during verification. In certain cases, we even encountered specifications that could not be verified using traditional pure event-based or state-based approaches, but became tractable within our state/event framework. We also recorded substantial reductions in time and memory consumption when performing deadlock-freedom checks with our new abstractions. Finally, we report two bugs (including a deadlock) in the source code of Micro-C/OS versions 2.0 and 2.7, which we discovered during our experiments.

上市公司财务危机预警模型效果比较研究

以2002—2004年深沪两市首次被ST的79家上市公司为研究对象,同时用79家盈利公司作配对样本,选择32个财务指标进行了Wilcoxon符号平均秩检验以判断选取指标的适宜性.运用Fisher二类线性判别分析和二元逻辑回归,分别建立起上市公司财务危机前的3年预警模型.结果表明,用这两种方法建立的模型的预测准确性均超过80%,但这两种方法建立模型的预测效果存在一定的差异.     

Children's attributions of intentions to an invisible agent.

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e., a light turning on/off; a picture falling), and children's behavioral response to these events (i.e., moving their hand to the opposite box) was coded. Results showed a significant Age Group × Experimental Condition interaction; the only children to reliably alter their behavior in response to the unexpected events were the oldest children (M = 7 years 4 months), who were primed with the invisible agent concept. For children's posttest verbal explanations, also, only these children saw the unexpected events as being referential and declarative (e.g., "Princess Alice did it because I chose the wrong box"). Together, these data suggest that children may not regularly begin to see communicative signs as embedded in unexpected events until they are around 7 years of age.

Social Crisis.

I am bewildered at the fact that the pages of the American Psychologist reflect almost no awareness of the tragic social upheaval which is accompanying the efforts of the American Negro to win his political, economic, and no less important, his psychological integration with the remainder of American society. This crisis will not disappear because we ignore it. It will be resolved one way or another. The Negro has apparently turned his face from acceptance of his unhappy circumstances and is determined to fight for his human and Constitutional rights. I think it is time that we, as a profession, give recognition to what is occurring around us, that we discuss what our role can and should be, and that each of us, in our own communities volunteer our services and our knowledge to work towards a just and peaceful integration of the American Negro into the American society of the twentieth century.
