Mood changes after self‐hypnosis and Johrei prior to exams
Authors: Laidlaw Tannis M. , Naito Akira , Dwivedi Prabudha , Enzor Nicholas A. , Brincat Christine E. , Gruzelier John H. 
Published: February 2006

AbstractBefore course examinations, 48 university students were randomized to four weeks of training in self‐hypnosis, a Japanese method for enhancing well‐being, Johrei, or to a control procedure shown to produce self‐reported relaxation and consisting of EEG‐biofeedback with false feedback. Participants were examined with mood scales, EEG and immune parameters on three occasions: prior to training, after the month of training, and again two to three months later. The mood results are reported here. Although all participants reported an increase in negative mood with exams, especially an increase in tension, both self‐hypnosis and Johrei buffered the effects of exam stress relative to the control group on depression, confusion and loss of vigour. These were extended with Johrei to include self‐rated anxiety, depression and anger, while self‐hypnosis evinced advantages over Johrei on diary reports of mood post‐training. The advantages immediately following training for self‐hypnosis and Johrei over the control relaxation procedure were to a large extent sustained at follow‐up, by which time home practice had reduced. Advantages were unrelated to expectations about outcome before training although beliefs after training were related to absorption abilities. Johrei appears a promising procedure for maintaining equilibrium of mood in the face of stress, despite the scepticism of the participants.

‘Magic Ian’: the use of sustained simile in the alleviation of serious behavioural disturbance and acute dyslexia in a 7‐year‐old boy
Authors: Callow Geoff 
Published: February 2006

AbstractThis paper outlines the case of a 7‐year‐old boy with severe dyslexia and severe behavioural difficulties. Removed by his parents from two primary schools to avoid permanent exclusion, he was educated in a specialist facility that focused on his literacy and behavioural difficulties. The paper considers the use of story telling using simile rather than metaphor as a therapeutic medium and argues that, in many cases and in this case, the technique is as effective as using metaphor in therapy.

The use of direct suggestion in the successful treatment of a case of snoring
Authors: Kraft Tom 
Published: February 2006

AbstractThis is a case study of a 53‐year‐old man who sought treatment for snoring. His motivation for treatment was that his wife could no longer tolerate the snoring so that he was forced to sleep in another room. The patient himself requested that I should use the direct suggestion that he turn over onto his side when snoring at night. It was shown that the snoring symptom lessened and his wife commented on this at a time when she was unaware that he was coming for treatment. The patient was also given direct suggestions to lose weight and, though at first he was reluctant to do this, later he was prepared to lose a stone in weight. After ten treatment sessions, the patient reported that the snoring symptom had been completely eliminated. At a follow‐up telephone interview three months later the patient reported that his improvement had been maintained. Copyright © 2003 British Society of Experimental and Clinical Hypnosis
New directions in forensic hypnosis: facilitating memory with a focused meditation technique
Authors: Wagstaff Graham , Brunas‐Wagstaff Joana , Cole Jon , Wheatcroft Jacqueline 
Published: February 2006

AbstractIn the late 1970s and early 1980s considerable publicity was given to the use of hypnosis as a technique to facilitate witness' memory in police investigations. As empirical evidence mounted, however, a number of limitations and disadvantages emerged with regard to the use of hypnosis in this role. As a consequence, hypnosis as an aid in forensic investigations is now treated with considerable caution and scepticism by many authorities, including the police. However, the present paper re‐examines some of the procedures employed in hypnotic interviewing that might still be useful in the development of brief memory facilitation procedures. In particular, a brief focused breathing meditation (FM) technique is described that uses elements common to hypnotic induction, but divorced from the context label of ‘hypnosis’. An experiment is described using this technique to aid face identification. As in other recent studies conducted by the authors, this procedure showed a memory facilitation effect, though without the increase in false positive errors familiar to more traditional hypnosis techniques; indeed, the trends were for FM to produce fewer false positive errors. Implications are discussed. Copyright © 2004 British Society of Experimental and Clinical Hypnosis
A case of driving phobia treated with dissociative imagery
Authors: Williamson Ann 
Published: February 2006

AbstractThis is a case study of a woman (Mrs T), who developed driving phobia following a traumatic incident two years previously whilst a passenger in a car. Treatment consisted of self‐hypnosis training, instituting a calmness anchor, and use of dissociative imagery using a cinema technique, together with positive mental rehearsal. There was full resolution after two sessions. Copyright © 2004 British Society of Experimental and Clinical Hypnosis
Relations between hypnotizability and psychopathology revisited
Authors: Gruzelier John , Pascalis Vilfredo De , Jamieson Graham , Laidlaw Tannis , Naito Akira , Bennett Bryan , Dwivedi Prabudha 
Published: February 2006

AbstractInspired by a first episode of schizophrenia following within a week of stage hypnosis, we examined relations between schizotypy and hypnotizability with the Harvard Group Scale of Hypnotic Susceptibility (HGSHS), showing positive associations with 15 items mostly consisting of positive aspects of schizotypy. Here this was re‐examined in two further samples. First, with the more cognitively loaded Stanford Hypnotic Susceptibility Scale, Form C, administered individually to Italian, female psychology students. In the second the HGSHS was administered to British medical student volunteers in stress reduction studies. In the first replication 12 correlations were disclosed, all with positive features of schizotypy, nine consisting of unreality experiences, with six items relating to psychic experiences. In the second replication of the 13 positive associations, seven were negative items belonging to the withdrawn syndrome, with six belonging to the social anxiety subscale, a non‐specific feature of schizotypy. Across the series of studies, all but one item was interpreted as consistent with associations between hypnotizability and positive schizotypy and social anxiety. Though the items mostly varied from study to study, and despite sampling and scale differences, the outcome clearly merits large scale studies to investigate further the relation between hypnotic susceptibility and psychopathology.

Looking over the shoulder of the hidden observer: is there anything for the hidden observer to observe?
Authors: Woody Erik , Sadler Pamela 
Published: February 2006

AbstractIn dissociation theory, a strong distinction needs to be drawn between the dissociated‐experience model and the dissociated‐control model. From the point of view of dissociated experience, a ‘hidden observer’ might conceivably make contact with effort expended but previously blocked from consciousness; however, from the point of view of dissociated control, the sense of hypnotic effortlessness was never illusory in the first place, and there is no hidden effort for the hidden observer to observe. Issues of study design, subject selection and dependent variables affect the ability to discriminate these models from each other and from sociocognitive theory.

The ‘hidden observer’ and ideomotor responding: a real‐simulator comparison
Authors: Green Joseph P. , Page Roger A. , Handley George W. , Rasekhy Rouhangiz 
Published: February 2006

AbstractSubjective reports of the amount of effort required to complete an ideomotor (i.e. arm suspension) task were contrasted across baseline, hypnosis, hidden observer and post‐session trials among N = 124 participants who had previously scored in the high or low range on a standardized measure of hypnotizability. Low hypnotizable participants received simulation instructions prior to the experiment. Three different instructions were administered during the hidden observer trial. Participants were told that their hidden observer would be: more aware of the effort required to complete the task; or less aware; or they received no specific instruction concerning how their hidden observer report should differ from their previously generated hypnosis report. Results showed that the wording of the instructions influenced hidden observer ratings for both real and simulating participants. Copyright © 2005 British Society of Experimental & Clinical Hypnosis.

Fine‐Tuning of Relative Metal–Metal Distances within Highly Ordered Chiral 2D Nanopatterns
Authors: Zell Philipp , Mögele Florian , Ziener Ulrich , Rieger Bernhard 
Published: March 2006

AbstractThe two‐dimensional nanopatterning of a series of neutral alkoxy/alkyl‐functionalised bis(salicylaldehydato)/bis(aldiminato)copper(II) and ‐palladium(II) complexes at a liquid/solid (highly oriented pyrolytic graphite, HOPG) interface has been studied by scanning tunnelling microscopy (STM). The relative metal–metal distances were tuned stepwise in two dimensions by ligand design. Exchange of the carbonyl O‐atom for NH or N‐alkyl units effects different intermolecular interactions such as weak hydrogen bonds and steric effects that determine, together with the van der Waals forces between the alkyl chains, the relative arrangements of the complexes. Further variation of the length and position of the alkoxy side chains as well as the exchange of CuII for PdII affords an absolute fine‐tuning of the surface structures. Highly resolved STM images of the resultant highly ordered adlayers allow us to establish detailed models of the molecular 2D arrays and to classify them into three basic chiral pattern types. Homochirality within the individual domains is induced by the highly regular deposition of the prochiral complexes from the same enantiotopic face. In the case of the C12 O‐substituted bis(salicylaldiminato) (NH) CuII complex Cu5, a secondary structure occurs as a racemic mixture of two chiral surface species deposited in a distinct alternating order.
X‐ray Diffraction and Theoretical Studies for the Quantitative Assessment of Intermolecular Arene–Perfluoroarene Stacking Interactions

Published: February 2006

AbstractThe arene–perfluoroarene stacking interaction was studied by experimental and theoretical methods. A series of compounds with different possibilities for formation of this recognition motif in the solid state were synthesized, and their crystal structures determined by single‐crystal X‐ray diffraction. The crystal packing of these compounds, as well as the packing of related compounds retrieved from crystallographic databases, were analyzed with quantitative crystal potentials: total lattice energies and the cohesive energies of closest molecular pairs in the crystals were calculated. The arene–perfluoroarene recognition motif emerges as a dominant interaction in the non‐hydrogen‐bonding compounds studied here, to the point that asymmetric dimers formed over the stacking motif carry over to asymmetric units made of two molecules in the crystal both for pure compounds and for molecular complexes; however, inter‐ring distances and angles range from 3.70 to 4.85 Å and from 5 to 21°, respectively. Pixel energy partitioning reveals that whenever aromatic rings stack, the largest cohesive energy contribution comes from dispersion, which roughly amounts to 20 kJ mol−1 per phenyl ring, while the coulombic term is minor but significant enough to make a difference between the arene–arene or perfluoroarene–perfluoroarene interactions on the one hand, and arene–perfluoroarene interactions on the other, whereby the latter are favored by about 10 kJ mol−1 per phenyl ring. No evidence of special interaction which can be attributed to H⋅⋅⋅F confrontation was recognizable.
A Photocatalytic Acid‐ and Base‐Free Meerwein–Ponndorf–Verley‐Type Reduction Using a [Ru(bpy)3]2+/Viologen Couple

Published: March 2006

AbstractA photocatalytic system to effect the Meerwein–Ponndorf–Verley reduction of carbonylic compounds to alcohols has been developed. The system comprises [Ru(bpy)3]2+ as a photosensitizer, triethanolamine as a sacrificial electron donor, viologen as an electron acceptor, and the carbonyl compound and iPrOH as Meerwein–Ponndorf–Verley reagents. The photocatalytic reaction can be performed in neat iPrOH or in 1‐butyl‐3‐methylimidazolium ionic liquid. Mass spectrometric detection of the viologen hydride derivative VH+ confirms that this species is the reducing agent responsible for the carbonyl compound reduction. The reaction intermediates involved in the photocatalytic system have also been characterized by laser flash photolysis.
Intramolecular Photoarylation of Alkenes by Phenyl Cations

Published: February 2006

AbstractAcetone‐sensitized irradiation of various o‐chlorophenyl allyl ethers in polar solvents led to either (dihydro)benzofurans or chromanes. The reaction appeared to involve photoheterolysis of the arylCl bond followed by phenyl cation addition onto the tethered double bond either in 5‐exo or 6‐endo modes. The adduct cation gave the end products by deprotonation; addition of chloride anion or of the solvent, depending on the structure; and the conditions used. Preference for the 5‐exo mode increased in passing from medium polarity (methylene chloride, ethyl acetate) to high polarity solvents (aqueous acetonitrile, methanol, 2,2,2‐trifluoroethanol), for which this was often the exclusive path. The same compounds underwent photohomolysis when irradiated in cyclohexane, and radical cyclization was one of the process occurring. Substitution of a methylene group for the ether oxygen atom made 6‐endo cyclization by far the main path in a related o‐chlorophenylbutene. Again, the selectivity was higher in polar protic solvents. The results are discussed in terms of in cage ion pair versus free phenyl cation reactions.
Facile and Versatile Annulation of the Imidazole Ring: Single and Sequential Cyclization Reactions of Fischer Carbene Complexes with 1,4‐Diazafulvenes

Published: February 2006

AbstractWe examined the reactivity of dimethylaminodiazafulvene 1 toward Fischer alkenylcarbene 2 and alkynylcarbene 3 complexes. Diazafulvene 1 reacts with alkenylcarbenes 2 through a formal [6+3] heterocyclization in a regio‐ and stereoselective manner to afford dihydroimidazo[1,2‐a]pyridines 4. Acid‐promoted dimethylamine elimination in compound 4 c gives rise to the aromatic imidazo pyridine 5. A likely mechanism for this reaction is a 1,2‐nucleophilic addition/[1,2]‐shift metal‐promoted cyclization sequence. On the other hand, diazafulvene 1 and alkynyl carbenes 3 undergo a [6+2] cyclization to afford pyrrolo[1,2‐a]imidazole carbene complex 6 that can be readily oxidized to the corresponding esters 7. When enynylcarbenes 3 e–i are treated with diazafulvene 1, consecutive and diastereoselective [6+2]/cyclopentannulation cyclization reactions take place affording new polycyclic complex systems 8, 9, and 12 that can be appropriately demetallated to the corresponding imidazole‐based polyfused systems 10, 11, and 13 respectively. Finally, enynylcarbenes 3 d,f undergo consecutive [6+2]/[5+1] cyclization reactions with diazafulvene 1 and tBuNC, respectively, to yield tetracyclic adducts 14 and 15. All these processes result in high yields and provide a route to the preparation of imidazopyridines and pyrroloimidazoles as well as other polycyclic molecules that contain imidazole groups, which are interesting from a pharmacological and biological point of view.

Published: March 2006

AbstractVarious nanostructured films of copper and silver tellurides were hydrothermally grown on the corresponding metal substrates through reactions between metal foils and tellurium powder in different media. Interesting morphologies including nanowires, nanorods, nanobelts, nanosheets, and hierarchical dendrites were obtained. The nanostructured films were characterized by using X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and high‐resolution TEM (HRTEM). A growth mechanism was proposed based on the characterization results. This study provides a low‐temperature, solution‐phase approach to grow low‐dimensional, nanostructured metal tellurides with controllable morphologies.

Authors: Zaubitzer Friederike , Buryak Andrey , Severin Kay 
Published: March 2006

AbstractIndicator‐displacement assays based on the organometallic complex [{Cp*RhCl2}2] (Cp*=pentamethylcyclopentadienyl) and the dye gallocyanine were used to sense amino sugars and aminoglycosides in buffered aqueous solution by conducting UV‐visible spectroscopy. The data of three assays at pH 7.0, 8.0, and 9.0 were sufficient to distinguish between the amino sugars galactosamine, glucosamine, mannosamine and the aminoglycosides kanamycin A, kanamycin B, amikacin, apramycin, paromomycin, and streptomycin. Furthermore, the assays were used to characterize mixtures of aminoglycosides and obtain quantitative information about the respective analytes.
[γ‐1,2‐H2SiV2W10O40] Immobilized on Surface‐Modified SiO2 as a Heterogeneous Catalyst for Liquid‐Phase Oxidation with H2O2

Published: March 2006

AbstractAn organic–inorganic hybrid support has been synthesized by covalently anchoring an N‐octyldihydroimidazolium cation fragment onto SiO2 (denoted as 1‐SiO2). This modified support was characterized by solid‐state 13C, 29Si, and 31P NMR spectroscopy, IR spectroscopy, and elemental analysis. The results showed that the structure of the dihydroimidazolium skeleton is preserved on the surface of SiO2. The modified support can act as a good anion exchanger, which allows the catalytically active polyoxometalate anion [γ‐1,2‐H2SiV2W10O40]4− (I) to be immobilized onto the support by a stoichiometric anion exchange (denoted as I/1‐SiO2). The structure of anion I is preserved after the anion exchange, as confirmed by IR and 51V NMR spectroscopy. The catalytic performance for the oxidation of olefins and sulfides, with hydrogen peroxide (only one equivalent with respect to substrate) as the sole oxidant, was investigated with I/1‐SiO2. This supported catalyst shows a high stereospecificity, diastereoselectivity, regioselectivity, and a high efficiency of hydrogen peroxide utilization for the oxidation of various olefins and sulfides without any loss of the intrinsic catalytic nature of the corresponding homogeneous analogue of I (i.e., the tetra‐n‐butylammonium salt of I, TBA‐I), although the rates decreased to about half that with TBA‐I. The oxidation can be stopped immediately by removal of the solid catalyst, and vanadium and tungsten species can hardly be found in the filtrate after removal of the catalyst. These results rule out any contribution to the observed catalysis from vanadium and tungsten species that leach into the reaction solution, which means that the observed catalysis is truly heterogeneous in nature. In addition, the catalyst is reusable for both epoxidation and sulfoxidation without any loss of catalytic performance.
A Positive‐Microemulsion Method for Preparing Nearly Uniform Ag2Se Nanoparticles at Low Temperature

Published: February 2006

AbstractA positive‐microemulsion system (water/sodium linoleate/hexane) was used to make uniform Ag2Se nanoparticles at low temperature (7–10 °C) within five to ten minutes. The proposed interface‐reaction mechanism was corroborated by transmission electron microscopy (TEM), IR spectroscopy, and X‐ray photoelectron spectroscopy (XPS) results. This is a general method that is ideal for making other uniform nanoparticles on a large scale through simple precipitation reactions.
