Contextualizing Images in Dreams and Daydreams

A contextualizing image (CI) is a powerful central image of a dream which appears to contextualize (provide a picture-context for) the dreamer's emotion. For instance, dreamers who have experienced any serious traumatic event sometimes dream, I was overwhelmed by a tidal wave. This appears to picture their feeling of terror and/or vulnerability.A scoring system for CIs is examined here and is applied to dreams and daydreams supplied by 40 students. Two raters scoring dreams on a blind basis showed good inter-rater reliability. Recent dreams were shown to have more as well as more intense CIs than recent daydreams; likewise, dreams that stand out had more intense CIs than daydreams that stand out. Students with thin boundaries had more and more intense CIs than students with thick boundaries in their recent dreams and nightmare, but not so clearly in dreams and nightmares that stand out. The emotions judged as contextualized by the powerful images tended towards fear/terror and helplessness/vulnerability in dreams (especially in dreams that stand out) whereas emotions contextualized by images in daydreams showed a wide range with no clusters.     

The Use of the Strauch Scale to Study Dream Reports from Sacred Sites in England and Wales

Thirty-five volunteers spent between one and five nights in one of four unfamiliar outdoor sacred sites in England and Wales where they were awakened following rapid eye movement periods and asked for dream recall. They also monitored their dreams in familiar home surroundings, keeping dream diaries. Equal numbers of site dreams and home dream reports were obtained for each volunteer. Two judges, working blind and independently, evaluated each of the resulting 206 dream reports, using the Strauch Scale which contains criteria for identifying bizarre, magical, and paranormal elements. Of the 103 site dream reports, 46 fell into one of these categories, versus 31 of the home dream reports. A number of explanations exist for this difference, including expectancy, suggestion, the effect of unfamiliar surroundings, the nature of the volunteers' awakenings, and possible anomalous properties of the sacred sites. The latter possibility, however, is unlikely due to the fact the 22 volunteers reported site dreams containing Strauch Scale items, while 20 reported home dreams containing these content items, a minimal difference.     

The Dream as Text, The Dream as Narrative

The concepts of text and narrative are reviewed in terms of their appropriate application to the study of dreams. It is proposed that, once experienced, all dreams are texts, but that not all of these texts are narratives. Blending Jung's proposal for the form of the average dream with basic terms from narratology, dream data are employed in order to examine the narrativity of dreams, and by way of inquiring into cognitive aspects of narrative structure. Questions about the relation between language and narrative structure on the one hand, and between dreaming and language on the other are also briefly taken up.     

We Do Not Dream of the 3 R's: Implications for the Nature of Dreaming Mentation

This report examines the extent to which dream recall involves the 3 R's (reading, writing, and arithmetic). Two separate studies were done. In the first study, two scorers rated, on a blind basis, a total of 456 written dream reports, available from five previous studies. There was perfect agreement between the two scorers. They agreed that there were no instances of reading, no instances of writing, and one instance of probable calculating in the 456 dreams. The second study was a questionnaire survey. Complete responses were obtained from 240 frequent dreamers (who reported remembering a mean of seven dreams per week). The study examined in two ways the frequency of the 3 R's in their recalled dreams. First, in answer to direct questions as to how frequently they dreamt about each activity, roughly 90% of the respondents reported that they never or hardly ever dreamt about each of four activities: reading, writing, typing, and calculating. In answers to other questions, this group reported spending a mean of six hours per day engaged in these activities. Second, responses as to the relative prominence of six activities (walking, writing, talking with friends, reading, sexual activity, typing) in dreaming versus waking produced two clear groupings of activities. Walking, talking with friends, and sexual activity were each rated almost as prominent in dreaming as in waking whereas the second group consisting of writing, reading, and typing were rated as far more prominent in waking than in dreaming. The two activity groups differed at p < .0001. Thus, the 3 R's appear to occur very infrequently in dreams. These findings are placed in a theoretical frame which suggests that dreaming (compared to waking) deals very little with serial activities characterized by input—rapid-processing—output in which the neural nets function in a feed-forward mode. Rather, dreaming may be characterized by relatively broad or loose connection making in which the nets function more in an autoassociative mode.     

Personal Boundaries and Nightmare Consequences in Frequent Nightmare Sufferers

According to the boundary concept of Hartmann (1991), the occurence of nightmares was repeatedly shown to be correlated to thin personal boundaries. The present study investigated the relationship between boundary thinness and emotional, cognitive, and behavioral consequences of nightmares in frequent nightmare sufferers. Occurence of nightmares and their respective consequences were recorded daily during a 4-week period by diaries and questionnaires. Confirming previous results, frequent nightmare sufferers had significantly thinner personal boundaries than occasional nightmare sufferers, and nightmare frequency was positively correlated to boundary thinness. In frequent nightmare sufferers, the emotional and cognitive consequences of a nightmare as well as its possible explanations were correlated to boundary thinness; mainly the personal total score and the Boundary Questionnaire scales sleep/wake/dreams, thoughts/feelings/mood and sensitivity. The results indicate that although nightmare frequency is positively correlated to thin personal boundaries, only particular aspects of the concept of personal boundaries are correlated to emotional and cognitive consequences of the nightmares.     

Does Dream Interpretation Have Any Limits? An Evaluation of Interpretations of the Dream of “Irma's Injection”

Dream interpretative efforts appear unconstrained by methodological standards. An examination of the re-interpretations of Freud's dream of Irma's Injection, the dream specimen of psychoanalysis, illustrates the undisciplined nature of dream interpretation. Reading in from presumed day residues or infantile experiences rather than out from the dream report per se lies at the heart of the problem. The failure to spell out inferences, to link inferences to the dream text, to explain and maintain the relationships in the dream report, and to offer a substitute text for the entire dream text all contribute to the inadequacies of dream interpreatation.     

The Significant Dream as Emblem of Uniqueness: The Fertilizer Does Not Explain the Flower

Recent, renewed attention to big or significant dreams calls into question many widely held assumptions about dreams. This essay focuses on the assumption that dreams can be accounted for in terms of the dominant emotions and concerns of the dreamer at the time of the dream. That assumption is found to be inadequate to account for at least some significant dream experiences. Archetypal psychology's aesthetic, phenomenological approach to dreams is presented as providing an instructive, illuminating alternative for understanding the on-going significance of significant dreams.     

Dream Bizarreness and Inner Thought

The paper offers a critique of bizarreness studies that compare dreams to real world probability ratios and directed thought processes as a basis for determining the degree of bizarreness in dreams. It examines two cases from the literature and suggests that dreams are better compared to non-directed, or imaginative waking thought processes, specifically Inner Thought and Speech (or speech for oneself, in Lev Vygotsky's definition), in which associative mechanisms operate freely hand in hand with (primarily) visual imagery before logical thought mechanisms come into play. The article suggests that dreams create a world order, or umwelt, with its own distinct cognitive domain in which waking considerations of efficiency, logic, and common sense are only thematically relevant. Dreams follow their own logic and can only be approached as thought-in-progress, or a search for coherence leading up many blind alleys. Finally, the relevance to dreams of the Inner Thought principle of predication, or abbreviation is examined.     

The On-Going Significance of Significant Dreams: The Case of the Bodiless Head

In the growing literature on significant dreams, relatively little attention has been given to the enduring, even life-long, influence some dreams have on dreamers' lives. This article describes an ongoing research project on significant dreams by way of an illustrative case of a young woman whose 20-year-old dream still resonates in her psychic life. We suggest that such dreams might be better understood in terms of the aesthetics of & #x201C;image rather than the interpretation of dreams as & #x201C;text.     

A New Neurocognitive Theory of Dreams

Discoveries in three distinct areas of dream research make it possible to suggest the outlines of a new neurocognitive theory of dreaming. The first relevant findings come from assessments of patients with brain injuries, which show that lesions in different areas have differential effects on dreaming and thereby imply the contours of the neural network necessary for dreaming. The second set of results comes from work with children ages 3–15 in the sleep laboratory, which reveals that only 20–30% of REM period awakenings lead to dream reports up to age 9 and that the dreams of children under age 5 are bland and static in content. The third set of findings comes from a rigorous system of content analysis, which demonstrates the repetitive nature of much dream content and that dream content in general is continuous with waking conceptions and emotional preoccupations. Based on these findings, dreaming is best understood as a developmental cognitive achievement that depends upon the maturation and maintenance of a specific network of forebrain structures. The output of this neural network for dreaming is guided by a continuity principle linked to current personal concerns on the one hand and a repetition principle rooted in past emotional preoccupations on the other.     

The dynamic effects of inputs to spinal motoneurones of different type upon the outputs of γ-motoneurones mediated via recurrent inhibition

A previous dynamic model of the spinal motoneurone-Renshaw cell system has been extended by integrating -motoneurones (-MNs), which are also supposed to represent Ia inhibitory interneurones mediating reciprocal inhibition. For the recurrent inhibition of -MNs, two cases are considered: -MNs inhibiting themselves via Renshaw cells (RCs), and -MNs not subjected to self-inhibition. Two input systems are taken into account: monosynaptic Ia input distributed inhomogeneously to the three types of -MNs (S, FR, and FF), and spinally descending input from the lateral vestibular nucleus distributed inhomogeneously to the three -MN types and to -MNs. Dynamic input-output relations have been calculated in form of Bode or polar plots. The main results are: Input signals (Ia and VST) to -MNs are transmitted via RCs to -MNs with high-pass characteristics (lower cut-off around 1 Hz). The relatively high gains at high frequencies are attenuated more or less strongly by recurrent self-inhibition of -MNs depending on the overall strength of recurrent inhibition. The phase lags of -MNs with respect to the input are not frequency-independent, but vary between about-90° and-180° (at times up to-200°). To preserve in-phase activation of -and -MNs, certain criteria have to be met which are discussed in terms of additional input systems to -MNs and RCs.     

Comparative residual toxicities of pesticides to the predator Agistemus industani (Acari: Stigmaeidae) on citrus in Florida

Residual toxicities of registered and selected experimental pesticides used on citrus against Agistemus industani Gonzalez (Acari: Stigmaeidae) were compared. Pesticides considered highly toxic to A. industani were: abamectin 0.15 EC at 731ml/ha+FC 435-66 petroleum oil at 46.8l/ha, pyridaben 75WP at 469g/ha, ethion 4EC at 7.01l/ha+FC 435-66 petroleum oil at 46.8l/ha, propargite 6.55 EC at 3.51l/ha, chlorfenapyr 2SC at 1.46l/ha applied alone or in combination with FC 435-66 petroleum oil at 46.8l/ha, sulphur 80DF at 16.81kg/ha, dicofol 4EC at 7.01l/ha, fenbutatin oxide 50WP at 2.24kg/ha, benomyl 50WP at 2.24kg/ha, benomyl 50WP at 1.68kg/ha+ferbam 76 GF at 5.60kg/ha, ferbam 76GF at 11.21kg/ha, neem oil 90EC at 46.8l/ha, and copper hydroxide DF (40% metallic copper) at 4.48kg metallic copper/ha+FC 435-66 petroleum oil at 46.8l/ha. Pesticides that were moderately to slightly toxic included: copper sulphate 98% at 4.48kg metallic copper/ha+FC 435-66 petroleum oil at 46.8l/ha, fenbuconazole 2F at 280ml/ha+FC 435-66 petroleum oil at 46.8l/ha, FC 435-66 petroleum oil applied alone at 46.8l/ha or 23.4l/ha, and diflubenzuron 25WP at 1.40kg/ha. Pesticides that were non-toxic included: fenbuconazole 2F at 585ml/ha, malathion 57EC at 5.85l/ha, FC 435-66 petroleum oil at 46.8l/ha, carbaryl 80S at 3.36kg/ha, chlorpyrifos 4EC at 4.68l/ha, and formetanate 92SP at 1.12kg/ha. Understanding the toxic effects of field weathered pesticides against key predacious mite species is important for effective IPM. The results of this study provide a comparison of direct and indirect toxic effects of various pesticides to A. industani under field conditions.     

Flexibility on the karyotype evolution in bitterlings (Pisces, Cyprinidae)

In bitterlings (Acheilognathinae) C- and Ag-banding karyotypes of 6 species-subspecies collected in China and South Korea were analyzed. The chromosomal constitution of 2n=46 (4SM+42ST) in Rhodeus atremius fangi was quite different from that of 2n=48 (8M+20SM+20ST) in other species-subspecies in Rhodeus. It was concluded from the analysis of banded chromosomes that the increase in number of ST during the karyotype change from 2n=48 to 2n=46 was achieved by a series of pericentric inversions from 24 M-SM to 24 ST, and the decrease in the diploid number was caused by an additional tandem fusion of 4 ST chromosomes, forming a new ST pair in the 2n=46 karyotype. The karyotype of Tanakia koreensis, T. signifer, and Acheilognathus macropterus is 2n=48 (8M+20SM+20ST), 2n=48 (8M+20SM+14–16ST+4–6 A), 2n=44 (14M+16SM+14ST), respectively. In R. ocellatus ocellatus, T. koreensis, T. signifer and A. macropterus, karyotype changes from 2n=48 to 2n=44 due to centric fusion and inversion have also been estimated. It was suggested that C-banding heterochromatin was greatly concerned with the karyotype evolution in bitterlings.     

Production of a novel syrup containing neofructo-oligosaccharides by the cells of Penicillium citrinum

A novel syrup containing neofructo-oligosaccharides was produced from sucrose (Brix 70) by whole cells of Penicillium citrinum. The efficiency of fructo-oligosaccharides production was more than 55% and those of the main carbohydrate components, 1-kestose (Fruf 21Fruf 21 Glc), nystose (Fruf 21Fruf 21 Fruf 21 Glc) and neokestose (Fruf 26 Glc12 Fruf), were 22, 14 and 11%, respectively.     

Binding of the galactose-specificPseudomonas aeruginosa lectin,PA-I,to glycosphingolipids and other glycoconjugates

The carbohydrate-binding specificity ofPseudomonas aeruginosa lectin I (PA-I) in iodinated or biotinylated form was studied. A large number of glycosphingolipids, as well as some glycoproteins and neoglycoproteins were used as ligands. Also, inhibition by free saccharides of PA-I binding to glycosphingolipids was tested. It was found that the lectin binds most strongly to terminal and nonsubstituted Gal3Gal- or Gal4Gal-structures.Abbreviations PA-I Pseudomonas aeruginosa lectin I - Cer ceramide - lactosylceramide Gal4GlcCer - iso globotriaosylcerami Gal3Gal4GlcCer - globotriaosylceramide Gal4Gal4GlcCer - globoside or globotetraosylceramide GalNAc3Gal4Gal4GlcCer - Forssman glycolipid GalNAc3GalNAc3Gal4Gal4GlcCer - P1 glycolipid Gal4Gal4GlcNAc3Gal4GlcCer - lactoneotetraosylceramide Gal4GlcNAc3Gal4GlcCer - B5 glycolipid Gal3Gal4GlcNAc3Gal4GlcCer - gangliotetraosylceramide Gal3GalNAc4Gal4GlcCer - GM1 Gal3GalNAc4(NeuAc3)Gal4GlcCer - RBC red blood cells - BSA bovine serum albumin - PBS phosphate-buffered saline - SDS sodium dodecyl sulfate - TLC thin-layer chromatography - HPLC high pressure liquid chromatography - MS mass spectrometry - FAB fast-atom bombardment - EI electron impact     

Occurrence of reducing terminal N-acetylglucosamine 3-sulfate and fucosylated outer chains in acidic N-glycans of porcine zona pellucida glycoproteins

Structures of acidic N-glycans released from porcine zona pellucida glycoproteins by hydrazinolysis were studied. The results indicated that the acidic glycans are of mono- to tetraantennary complex-type with and without N-acetyllactosamine repeating units. Sulfated residues are not only located at the C-6 position of GlcNAc included in the N-acetyllactosamine repeating units, but also at the C-6 position of GlcNAc in the non-repeated antennae and at the C-3 position of reducing terminal GlcNAc residue. Analysis of the oligosaccharide fragments released by endo--galactosidase digestion and by hydrazine/nitrous acid treatment also revealed that various sulfated and non-sulfated forms of fucosylated structures such as Fuc12Gal14(±SO–36)GlcNAc (type 2H), Gal14(Fuc13)(±SO–36)GlcNAc(Lex) and Fuc13 or 4(±SO–36)GlcNAc, are expressed in the repeated outer chain moieties.     

Adoptions expérimentales de larves entre des fourmis de genres différents:Leptothorax nylanderi Förster etSolenopsis fugax Latreille

Résumé En l'absence de son propre couvain,Solenopsis fugax a élevé des larves deLeptothorax nylanderi, à la température de 22°C. Les ouvrières deSolenopsis détruisirent une partie de ces larves mais nourrirent celles qu'elles épargnèrent; ces dernières grossirent lentement pendant cinq à six mois, sans atteindre le stade prénymphe. Lorsque les ouvrières deS. fugax et les larves deL. nylanderi furent soumises ensemble à un hivernage préalable, elles donnèrent les mêmes résultats que sans hivernage. La présence d'une jeune reine deSolenopsis fut défavorable aux larves deLeptothorax.Inversement,L. nylanderi fut capable d'élever, à la température de 22°C, des larves deS. fugax et de les amener jusqu'au stade adulte. En présence de leurs propres larves, les ouvrières deL. nylanderi détruisirent tapidement toutes les larves deS. fugax introduites dans leur nid. D'autre part, un jeune couvain deLeptothorax remplaçait plus ou moins rapidement les larves deLeptothorax enlevées au préalable; sa présence était alors défavorable au développement des larves deSolenopsis. Un hivernage en début d'expérience fut plutôt favorable auxS. fugax, de même que la présence d'une reine féconde deLeptothorax. LesSolenopsis ainsi obtenus n'ont pas vécu plus de sept semaines. Ils étaient tous de caste ouvrière et de taille très petite.

Summary When its own eggs and larvae missed,Solenopsis fugax bred larvae ofLeptothorax nylanderi, at a temperature of 22°C. TheSolenopsis workers killed some of this larvae and fed the others; these slowly grew bigger during five or six months but never reached the pre-pupa stage. The result was the same if the workers ofS. fugax and the larvae ofL. nylanderi overwintered together or not at all. A youngSolenopsis queen being there was noxious to the larvae ofLeptothorax.On the contrary,L. nylanderi has been able to breed larvae ofS. fugax up to the imago stage, at a temperature of 22°C. When its own larvae were in the nest, together with larvae ofS. fugax, the workers ofL. nylanderi killed the larvae ofS. fugax. On the other hand, new eggs and young larvae ofLeptothorax had to replace, more or less quickly, the larvae which had been taken away, and that was noxious to the growth ofSolenopsis larvae. An overwintering at the beginning of the experiment was rather favourable toS. fugax as was the presence of a fecundLeptothorax queen. TheSolenopsis thus obtained lived no longer than seven weeks. They all were workers and very small.

Large scale preparation of PA-oligosaccharides from glycoproteins using an improved extraction method

We have developed a new method for the large scale preparation of pyridylaminated (PA-) oligosaccharides from glycoproteins. Phenol/chloroform extration was adapted for the removal of protein and excess 2-aminopyridine, improving the efficiency of preparation. From a 2.5 g sample of human apo-transferrin, 25–30 mol of agalacto biantennary PA-oligosaccharide could be obtained. By increasing the concentration of PA-oligosaccharide substrate, we were able to detect a very low level ofN-acetylglucosaminlytransferase IV activity in CHO cell extracts.Abbreviations PA 2-aminopyridine - SDS sodium dodecyl sulfate - GlcNAc N-acetylglucosamine - GnT N-acetylglucosaminyltransferase - Gn,Gn-bi-PA GlcNAc1-2Man1-3(GlcNAc1-2Man1-6)Man1-4GlcNAc1-4GlcNAc-2-aminopyridine - Gn,Gn,Gn-tri-PA GlcNAc1-2(GlcNAc1-4)Man1-3(GlcNAc1-2Man1-6)Man1-4GlcNAc1-4GlcNAc-2-aminopyridine - Gn,Gn,Gn-trí-PA GlcNAc1-2Man1-3({GlcNAc1-2(GlcNAc1-6)Man1-6})Man1-4GlcNac1-4GlcNAc-2-aminopyridine - Gn,(Gn),Gn-bi-PA GlcNAc1-2Man1-3(GlcNAc1-4)(GlcNAc1-2Man1-6)Man1-4GlcNAc1-4GlcNAc-2-aminopyridine
