Nouvel essai de classification et de structuration des motifs des gravures rupestres du Haut Atlas (vallée de l'Ourika, Maroc)

We have been sometimes forced to notice that there are forgotten rupestral arts: until recently, they were only studied by explorers or informed travellers and are rarely reported in the scientific literature. This is in part the case of engravings in the Moroccan High Atlas to which I have devoted my research (Ezziani, 2002, 2004a, 2004b). J Malhomme is among the people who were most invested in their investigation. He spent ten years in noting and collecting a considerable number of engravings: more than one thousand figures dispersed on the sides of the Atlas in places of difficult access at more than 2000 masl. He published many papers about his discoveries, which led to the publication of a remarkable corpus in two parts (Malhomme, 1959-1961). However, this corpus is far from being exhaustive. Recently, A. Rodrigue carried out new and excellent drawings within his research activity (1996). He added to the corpus of Malhomme a large number of figures discovered by A. Simoneau (1967, 1968, 1970), A. Jodin (1964, 1966) (two other researchers who have been closely interested in the High Atlas engravings) and himself, but unfortunately some engravings were damaged: whole flagstones have disappeared, so that the original drawings from Malhomme still remain very useful. All these data constituted the documentation base of my own work. In this paper, first I review some classification methods, then I propose my own and point out the inherent difficulties in this task. I conclude with a proposal for an outline of the structure of the High Atlas engravings.     

Contemporary chinese sex symbols in dreams.

A list of sex symbols was derived from a thorough review of the sexual analogies that Chinese people most often use in slang language. This list, together with the Marlowe-Crowne Social Desirability Scale and the Eysenck Personality Questionnaire Revised–Short Form, was administrated to a sample of 608 upper-secondary school graduates from Hong Kong. It was found that the participants rarely dreamed about food analogies for sex, such as “eating litchis” and “bananas or banana-like objects.” By contrast, sex symbols involving weapons and aggressive behavior, such as “knives, swords, or daggers” and “shooting,” occurred in dreams with moderate prevalence rates. Moreover, gender, the frequency of dreaming sexual experiences, and social desirability significantly predicted the frequency scores on the scale formed by these aggressive symbols for sex.

Publication bias: evidence of delayed publication in a cohort study of clinical research projects.

OBJECTIVES: To determine the extent to which publication is influenced by study outcome. DESIGN: A cohort of studies submitted to a hospital ethics committee over 10 years were examined retrospectively by reviewing the protocols and by questionnaire. The primary method of analysis was Cox''s proportional hazards model. SETTING: University hospital, Sydney, Australia. STUDIES: 748 eligible studies submitted to Royal Prince Alfred Hospital Ethics Committee between 1979 and 1988. MAIN OUTCOME MEASURES: Time to publication. RESULTS: Response to the questionnaire was received for 520 (70%) of the eligible studies. Of the 218 studies analysed with tests of significance, those with positive results (P < 0.05) were much more likely to be published than those with negative results (P > or = 0.10) (hazard ratio 2.32 (95% confidence interval 1.47 to 3.66), P = 0.0003), with a significantly shorter time to publication (median 4.8 v 8.0 years). This finding was even stronger for the group of 130 clinical trials (hazard ratio 3.13 (1.76 to 5.58). P = 0.0001), with median times to publication of 4.7 and 8.0 years respectively. These results were not materially changed after adjusting for other significant predictors of publication. Studies with indefinite conclusions (0.05 < or = P < 0.10) tended to have an even lower publication rate and longer time to publication than studies with negative results (hazard ratio 0.39 (0.13 to 1.12), P = 0.08). For the 103 studies in which outcome was rated qualitatively, there was no clear cut evidence of publication bias, although the number of studies in this group was not large. CONCLUSIONS: This study confirms the evidence of publication bias found in other studies and identifies delay in publication as an additional important factor. The study results support the need for prospective registration of trials to avoid publication bias and also support restricting the selection of trials to those started before a common date in undertaking systematic reviews.     

Receptor Adaptive Responsiveness in Disease Models: 6-Ohda Lesioned and Spontaneously Hypertensive Rats

Abstract

We have examined the adaptive modifications of brain monoamine receptors in response to pathophysiological processes in animal disease models: 6-OHDA lesioned and spontaneously hypertensive rats (SHR).

The two models share a similar increase in D-1 receptor densities, while noradrenergic receptors are affected in different way: α;-1 and β are supersensitive in 6-OHDA lesioned rats and only α;-2 are increased in SHR. S-1 receptors too are up-regulated in SHR. We must notice that though receptor hypersensitivity in the 6-OHDA model is linked to massive decreases in neurotransmitter levels, this mechanism seems not to exist in the SHR model.

Distribution of bacterial populations in a stratified fjord (mariager fjord, denmark) quantified by in situ hybridization and related to chemical gradients in the water column

Volume 62, no. 4, p. 1391-1404: after publication of this article, it was brought to the attention of the authors that a more extensive treatment of the hydrodynamics of Mariager Fjord and the vertical distribution of bacteria and protozoa therein was published in a recent article by Fenchel et al. This work contains important information about the studied ecosystem, but unfortunately, the existence of this work was realized only after publication of our article. Thus, the following reference should have been cited in our article: [This corrects the article on p. 1391 in vol. 62.].

Helicobacter pylori infection and colorectal cancer risk: a meta-analysis

BACKGROUND: Several studies suggested an association between Helicobacter pylori infection and colorectal carcinoma or adenoma risk. However, different authors reported quite varying estimates. We carried out a systematic review and meta-analysis of published studies investigating this association and paid special attention to the possibility of publication bias and sources of heterogeneity between studies. Materials and METHODS: An extensive literature search and cross-referencing were performed to identify all published studies. Summary estimates were obtained using random-effects models. The presence of possible publication bias was assessed using different statistical approaches. RESULTS: In a meta-analysis of the 11 identified human studies, published between 1991 and 2002, a summary odds ratio of 1.4 (95% CI, 1.1-1.8) was estimated for the association between H. pylori infection and colorectal cancer risk. The graphical funnel plot appeared asymmetrical, but the formal statistical evaluations did not provide strong evidence of publication bias. The proportion of variation of study results because of heterogeneity was small (36.5%). CONCLUSIONS: The results of our meta-analysis are consistent with a possible small increase in risk of colorectal cancer because of H. pylori infection. However, the possibility of some publication bias cannot be ruled out, although it could not be statistically confirmed. Larger, better designed and better controlled studies are needed to clarify the situation.

Developing a register of randomised controlled trials in primary care.

OBJECTIVE--To determine the number, nature, site of publication, and feasibility of identifying randomised controlled trials relevant to primary care. DESIGN--Review of literature using three strategies: approaching journal editors, Medline search, and manual search of individual journals. SETTING--Journals containing publications of studies based in primary care. MAIN OUTCOME MEASURES--The number, site of publication, and subject of trials identified. RESULTS--No journal had a system which enabled identification of all the randomised controlled trials it published. 266 trials relevant to primary care were identified from 110 different journals during 1987-91 by Medline. Of these, only 62 trials were published in primary care journals. Hand searching of seven major primary care research journals showed that between 13% and 38% of the trials had been missed by the Medline search. Of the trials identified, 47 (18%) were concerned with mental disease (including neuroses, tobacco misuse and alcohol misuse) and 43 (16%) were concerned with hypertension. CONCLUSION--Given the diversity of publication sources and topics, this supports the need for a centrally based register of randomised controlled trials that may be relevant to primary care overviews in the future.

Following 411 Cochrane protocols to completion: a retrospective cohort study

Background

Cochrane reviews are regarded as being scientifically rigorous and are increasingly used by a variety of stakeholders. However, factors predicting the publication of Cochrane reviews have never been reported. This is important because if a higher proportion of Cochrane protocols with certain characteristics (e.g., funding) are being published, this may lead to inaccurate decisions. We examined the frequency of published and unpublished Cochrane reviews and protocol factors that predict the publication of Cochrane reviews.

Methodology/Principal Findings

Retrospective cohort study of Cochrane protocols published in 2000 (Issues 2 to 4) and 2001 (Issue 1). The publication status of these reviews was followed up to Issue 1, 2008 in The Cochrane Library. Survival analysis of the time from protocol publication to the first review publication and protocol factors predicting the time to publication was conducted. There were 411 new Cochrane protocols in the cohort. After excluding 39; 71/372 (19.1%) were unpublished and 301/372 (80.9%) were published as full Cochrane reviews at the time of study analysis (January 2008). The median time to publication was 2.4 years (range: 0.15 to 8.96). Multivariate analyses revealed that shorter time to publication was associated with the review subsequently being updated (hazard ratio, HR: 1.80 [95% confidence interval, CI: 1.39 to 2.33 years]) and longer time to publication was associated with the review having two published protocols, indicating changes to the review plan (HR: 0.33 [95% CI: 0.12 to 0.90 years]).

Conclusions/Significance

Only about 80% Cochrane protocols were published as full reviews after over 8 years of follow-up. The median time to publication was 2.4 years and some reviews took much longer. Strategies to decrease time to publication should be considered, such as streamlining the review process, increased support for authors when protocol amendments occur, and better infrastructure for updating Cochrane reviews.
