L’optimisation des réseaux cellulaires assistée par ordinateur: le logiciel RNO (Radio Network Optimisation)

Quality of service has become today a major concern for operators of mobile communication networks. The massive development of networks and strong competition between operators has lead to the necessary and daily follow-up of network quality of service, a key factor for its subscriber’s fidelity. This article aims at presenting the optimization methodology and proposes its illustration with a case of RNO (Radio Network Optimisation) software usage, one of the Alcatel optimization toolchain component. After a short presentation of cellular network, the optimization basic principles are described. RNO software and its main functionnalities are then detailed before a last part dedicated to a real case of optimization done with RNO software.     

The "hidden observer" phenomenon in hypnosis: Some additional findings.

23 highly hypnotizable undergraduates (Harvard Group Scale of Hypnotic Susceptibility) underwent 2 specially constructed 7-item hypnotic inductions. Over the 14 items, the main finding was of a relationship between E. R. Hilgard's (1973, 1977, 1979) "hidden observer" effect and 2 aspects of hypnotic age regression. Ss reporting a hidden observer experienced duality during regression to age 5, in which they were aware of being both adult and child. When asked to write a complex sentence, most did so, usually without spelling errors. The Ss not reporting this effect experienced quasi-lateral age regression in which they had the exclusive feeling of being 5 yrs old, with no sense of an adult identity. Most of these Ss were unable to write the same complex sentence when requested to during age regression. The study replicated Hilgard's finding of the hidden observer phenomenon in terms of its incidence and obtained similar verbal reports from Ss experiencing it. At the same time, the results suggest that a neodissociation account of hypnosis may need some modifications to accommodate these additional findings.

Hypnotic susceptibility and verbal automaticity: Automatic and strategic processing differences in the Stroop color-naming task.

The original hypothesis of M. Dixon et al (1990) that highly hypnotizable (HH) Ss process words more automatically than do low hypnotizable (LH) Ss was retested in a paradigm that separated strategic from automatic processes in the Stroop color-naming task. The words red and blue preceded a color patch that was red or blue. Ss were told that the word predicted the opposite color 75% of the time. Automatic and strategic processes were assessed by varying interstimulus interval (ISI) between the word and the color patch. Both HH and LH Ss showed significant strategic effects (faster incongruent-trial, color-naming reaction times [RTs] than congruent-trial RTs at ISIs over 400 msec), but only HH Ss showed significant automaticity (significantly faster congruent-trial RTs than incongruent-trial RTs at 16.7 msec, the lowest ISI).

The enhancement of memory by hypnosis in the legal investigative situation.

The increasing use of hypnosis on North America to enhance or refresh the memories of victims and witnesses of crime is creating concern, both within the professional hypnosis societies and within the legal profession. The authors review current positions on the issue and survey clinical and experimental data bearing on the efficacy of hypnosis as a means of memory enhancement. The 2 main problems associated with the use of hypnosis in the legal investigative context—confabulation and the creation of pseudo-memories—are discussed, with particular reference to the demand characteristics of the investigative context. Some recent court cases where confabulation was demonstrated unequivocally and several recent American state supreme court rulings are presented. The need for stringent safeguards proposed by M. T. Orne (1978) is discussed, and the relevance of the American experience of the past 15 yrs to the Canadian context is emphasized.

Hypnosis, surgery, and mind–body interaction: An historical evaluation.

Maintains that hypnosis is one of the many means for understanding mind–body interactions. Hypnosis has been shown to be effective in the treatment of asthma, dermatological conditions, burns, clinical pain, and perhaps some forms of cancer. The less researched area of surgical pain is the focus of the present study, with particular emphasis on surgeries performed in the 19th century, both before and after safe and effective chemical anesthetics were developed. Some of the modern scepticism toward such reports, which attempt to dismiss them in terms of social-psychological variables is discussed, as are the mechanisms underlying hypnotic responsivity as indicated by both current theorizing and research. It is concluded that the mechanisms underlying high hypnotic responsivity involve imagination in which a person becomes deeply involved to the extent that critical judgment is superseded. While these observations may have profound implications for the understanding of some of the processes underlying health and illness, the mechanisms by which semantic messages are converted to somatic ones are still not at all understood.

Hypnotizability, preference for an imagic cognitive style, and memory creation in hypnosis.

We sought to extend the finding (J.-R. Laurence and C. Perry, 1983) that it is possible through hypnosis to create a pseudomemory of a specific event. Subjects were compared on their responses to a hypnotic suggestion. We also examined the relation between nonhypnotic measures (Preference for an Imagic Cognitive Style [PICS] test and the Tellegen Absorption Scale [TAS]) and response to the suggestion. Highly (45.45%) and moderately-highly (46.15%) susceptible subjects believed that the pseudomemory was veridical, but none of the low susceptible subjects did so. Together, hypnotic susceptibility, the PICS, and their interaction more strongly predicted pseudomemory creation than any of these main effects alone. Performance on the TAS was also related to the occurrence of pseudomemory, but this relation was redundant with performance on other measures. These results point to the complexity of the variables involved in pseudomemory creation during hypnosis. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Multiscale investigation of graphene layers on 6H-SiC(000-1)

In this article, a multiscale investigation of few graphene layers grown on 6H-SiC(000-1) under ultrahigh vacuum (UHV) conditions is presented. At 100-μm scale, the authors show that the UHV growth yields few layer graphene (FLG) with an average thickness given by Auger spectroscopy between 1 and 2 graphene planes. At the same scale, electron diffraction reveals a significant rotational disorder between the first graphene layer and the SiC surface, although well-defined preferred orientations exist. This is confirmed at the nanometer scale by scanning tunneling microscopy (STM). Finally, STM (at the nm scale) and Raman spectroscopy (at the μm scale) show that the FLG stacking is turbostratic, and that the domain size of the crystallites ranges from 10 to 100 nm. The most striking result is that the FLGs experience a strong compressive stress that is seldom observed for graphene grown on the C face of SiC substrates.     

Hypnotizability and automaticity: Toward a parallel distributed processing model of hypnotic responding.

Tested a hypothesis from parallel distributed processing theory that highly hypnotizable Ss have greater connection strengths along verbal pathways and would show greater Stroop effects than low hypnotizable Ss. Using the paradigm from J. Cheesman and P. M. Merikle (see record 1989-03722-001) which varied cue visibility and probability, automatic and strategic effects on Stroop performance were assessed. Compared with 9 low and 9 moderately hypnotizable Ss, 9 highly hypnotizable ones showed significantly greater Stroop effects for both visible- and degraded-word trials. No strategic differences emerged for the 3 hypnotizability groups. These findings support the contention that highly hypnotizable persons have stronger verbal connection strengths than their moderately and low susceptible counterparts, and they may account for highly hypnotizable persons' propensity to disregard personal attributions and label their responses in hypnosis as being involuntary.

"Hidden observer" phenomenon in hypnosis: An experimental creation?

N. P. Spanos and E. C. Hewitt (see record 1981-26428-001) argued that E. R. Hilgard's (e.g., 1979) "hidden observer" phenomenon was a pure laboratory artifact. The present authors reevaluate the Spanos and Hewitt experiment and argue that they do not provide the empirical data to support their conclusions. Several aspects of Spanos and Hewitt's methodological procedures that need to be elucidated before their conclusion is justified are examined.
