Multidimensional representations of gender in French language publications for children. Gender stereotypes in French language literature for children have not been extensively studied. This study analyses stories with household heroes, in French language publications aimed at pre-school age children. The aim is to evaluate multidimensional representations of gender in these publications. Results reveal major quantitative and qualitative asymmetries in the representations of the two sexes, often to the detriment of the female. Males outnumber females, who more often play secondary roles as compared to males who are more often depicted in the central role; girls are less frequently represented in the illustrations accompanying these stories than boys. Females are depicted in a more stereotyped manner, and are more confined to domestic and in private locations. Additionally, women play a smaller variety of professional roles than men. The asymmetries highlighted in this study are discussed in terms of the influence that may be exercised over children’s construction of their gender identity, and influence particularly on the self-esteem and future aspirations of girls.
GLASS MODEL, HUBBARD MODEL AND HIGH-TEMPERATURE SUPERCONDUCTIVITY

Published: April 2003

In this paper we revisit the glass model describing the macroscopic behavior of the High-Temperature superconductors. We link the glass model at the microscopic level to the striped phase phenomenon, recently discussed widely. The size of the striped phase domains is consistent with earlier predictions of the glass model when it was introduced for High-Temperature Superconductivity in 1987. In an additional step we use the Hubbard model to describe the microscopic mechanism for d-wave pairing within these finite size stripes. We discuss the implications for superconducting correlations of the Hubbard model, which are much higher for stripes than for squares, for finite size scaling, and for the new view of the glass model picture.
THE RENNER MONOIDS AND CELL DECOMPOSITIONS OF THE SYMPLECTIC ALGEBRAIC MONOIDS
Authors: LI ZHENHENG , RENNER LEX E. 
Published: April 2003

In this paper we explicitly determine the Renner monoid ℛ and the cross section lattice Λ of the symplectic algebraic monoid MSpn in terms of the Weyl group and the concept of admissible sets; it turns out that ℛ is a submonoid of ℛn, the Renner monoid of the whole matrix monoid Mn, and that Λ is a sublattice of Λn, the cross section lattice of Mn. Cell decompositions in algebraic geometry are usually obtained by the method of [1]. We give a more direct definition of cells for MSpn in terms of the B × B-orbits, where B is a Borel subgroup of the unit group G of MSpn. Each cell turns out to be the intersection of MSpn with a cell of Mn. We also show how to obtain these cells using a carefully chosen one parameter subgroup.
Selenium in Breast Cancer
Authors: Lopez-Saez Juan-Bosco , Senra-Varela Avelino , Pousa-Estevez Lorenzo 
Published: April 2003

<i>Aim:</i> Controversy surrounds the hypothetical relationship between low serum levels of selenium and reduced activity of selenium-dependent enzymes, such as glutathione peroxidase, and an increased risk of cancer in humans. This study investigated serum concentrations of selenium in women with and without breast cancer. <i>Methods:</i> In this case-control study, we compared serum concentrations of selenium in women with breast cancer (n = 200), healthy women (n = 100), and women with chronic diseases (n = 100). Patients with breast cancer were divided into premenopausal (n = 99) and postmenopausal subjects (n = 101). <i>Results:</i> Mean serum concentrations of selenium were 81.1 µg/l in women with breast cancer and 98.5 µg/l in women with non-tumoral disease (p < 0.001). <i>Conclusion:</i> Alterations in serum concentrations of selenium in women with breast cancer appear to be a consequence, rather than a cause of cancer. In accordance with the hypothesis, the findings suggest that very low selenium status could be due to the nature of cancer.

Published: April 2003

Vocal loading-related subjective symptoms were studied in a day-long vocal loading test. The voices of 40 female and 40 male voluntary young students were loaded by having them read aloud a novel for five times 45 min. The subjective symptoms that occurred during the vocal loading session were reported by filling in a questionnaire after each session. The responses loaded on five factors in a factor analysis: (1) ‘central fatigue’; (2) ‘symptoms of the neck, shoulders and back’; (3) ‘drying in the mouth and throat’; (4) ‘symptoms of the throat’; (5) ‘symptoms of the voice’. The exposure groups (5 females and 5 males per cell) consisted of eight combinations of the following factors: (1) low (25 ± 5%) or high (65 ± 5%) relative humidity of ambient air; (2) low [<65 dB(SPL)] or high [>65 dB(SPL)] speech output level of vocal loading; (3) sitting or standing posture during vocal loading. The lowest mean score for symptoms pooled over the test were found in ‘symptoms of the neck, shoulders and back’ and the highest mean symptom score in ‘drying in the mouth and throat’ and ‘symptoms of the throat’. Most symptoms were at their minimum during the first loading session and increased statistically significantly to a peak mean value after three or five vocal loading sessions. Statistically significant differences in the mean level between the gender or exposure groups emerged for ‘central fatigue’ (humidity had clear effects) and ‘symptoms of the neck, shoulders and back’ (gender, humidity and posture had clear effects). In these cases, females had more symptoms than males; the low-humidity group had more symptoms than the high-humidity group, and the standing subjects had more symptoms than the sitting subjects.
ABRAHAM'S INCESTUOUS MARRIAGE WITH SARAH: A VIOLATION OF THE HOLINESS CODE
Authors: Hepner Gershon 
Published: April 2003

AbstractVerbal resonances suggest that Abraham's claim that Sarah is his half-sister in Gen. xx 13 indicates that he violates the prohibition of sibling incest in Lev. xx 17. This observation links Abraham not only to Amnon who has an incestuous relationship with his half-sister Tamar but to David who has an incestuous relationship with his halfsister Abigail after the death of her husband Nabal. The narrative of the conception of Moab, the son born to Lot after his unwitting incestuous relationship with his younger daughter, precedes the narrative in which Abraham admits that Sarah is his half-sister and is followed by the birth of Isaac, suggesting that the Torah implies that Isaac is no less the product of an incestuous relationship that violates the Holiness Code than Moab, an ancestor of David and Perez who is born as a result of an unwitting incestuous relationship between Judah and Tamar.
Estimation and prediction with ARMMAX model: a mixture of ARMAX models with common ARX part
Authors: He Li , Kárný Miroslav 
Published: April 2003

AbstractBayesian parameter estimation and prediction of a linear‐in‐parameters model with coloured noise is addressed, based on a novel mixture model called ARMMAX. ARMMAX is a finite mixture with its ARMAX components having a common ARX part. It assumes that the common ARX part describes a fixed deterministic input–output relationship and allows for varying characteristics of the driving coloured noise. The ARMMAX model with fixed MA parts is estimated by a specific version of recursive Quasi‐Bayes (ARMMAX‐QB) algorithm. It rests on a classical Bayesian solution that requires no restrictions on MA part allowing it to be even at the stability boundary.For on‐line use, the ARMMAX model offers flexibility with respect to varying characteristics of the model noise. The flexibility gained is paid by a slight increase of the computational burden when compared with the single ARMAX with known MA part, which is, in this respect, close to recursive least‐squares estimation.For off‐line use, the ARMMAX model offers the possibility to estimate the unknown MA part in a novel way. Exploiting the natural parallelism of the ARMMAX model, a robust, derivative free multi‐directional search (MDS) is selected to deal with extensive data sets for which universal optimization tools are too cumbersome.The paper motivates the modelling approach, describes algorithmic ingredients and illustrates the resulting algorithm using a simple example.

Control of induction motors: an adaptive passivity MIMO perspective
Authors: Duarte‐Mermoud Manuel A. , Travieso Juan C. 
Published: April 2003

AbstractThe design of two multiple‐input multiple‐output (MIMO) controllers for induction motors, based on adaptive passivity, is presented in this paper. The controller design method is based on concepts of equivalence passivity via adaptive feedback, previously developed by the authors. Robustness under variations of the motor‐load parameters is guaranteed and the knowledge of such a parameters is not needed in the design. Simple proportional controllers for the torque, rotor flux and stator current control loops are used, due to the control simplification introduced by the use of feedback passive equivalence. A principle called ‘Torque‐Flux Control Principle’ is used in this article introducing a considerable simplification in the resultant controller. Because of the employment of this principle, the control efforts are diminished and rotor flux estimation (or measurement) is avoided. Copyright © 2003 John Wiley & Sons, Ltd.
Unique mosaicism of structural chromosomal rearrangement: Is chromosome 18 preferentially involved?
Authors: de Pater J.M. , Smeets D.F.C.M. , Scheres J.M.J.C. 
Published: April 2003

AbstractThe mentally normal mother of a 4‐year‐old boy with del(18)(q21.3) syndrome was tested cytogenetically to study the possibility of an inherited structural rearrangement of chromosome 18. She was found to carry an unusual mosaicism involving chromosomes 18 and 21. Two unbalanced cell lines were seen as derivatives of a reciprocal translocation t(18;21), resulting in mosaicism of two cell lines, one with partial monosomy 18q and one with partial trisomy 18q. A literature review revealed that mosaicism of two or more cell lines with different unbalanced structural aberrations is extremely rare; moreover, chromosome 18 appeared to be involved in the majority of cases. We discuss possible mechanisms for the origin of this distinctive chromosomal constitution. © 2003 Wiley‐Liss, Inc.
A boy with developmental delay, malformations, and evidence of a connective tissue disorder—possibly a new type of cutis laxa
Authors: Armstrong Linlea , Jimenez Carmencita , Hunter Alasdair G.W. 
Published: April 2003

AbstractWe report a 7.5‐year‐old boy with loose translucent skin, aortic dilatation, hyperextensible veins, recurrent respiratory problems, pectus excavatum, arthralgias, lax joints, mild epiphyseal dysplasia, and umbilical and inguinal hernias. He also has developmental delay, progressive bilateral sensorineural hearing loss, an unusual facial appearance, terminal digit hypoplasia with unusual radiographic changes in some of the phalanges, glandular hypospadias, shawl scrotum, and undescended testes. Biochemical investigations, including electrophoresis of Types 1 and 3 procollagens and collagens, and quantification of serum copper and ceruloplasmin, are normal. Relative to age‐matched control patients the electron micrographs of the boy's dermis show elastin fibers to be decreased in number, and abnormal in appearance, with a low matrix to microfibril ratio. The organ distribution of abnormalities and the nature of the findings suggest a connective tissue disorder. We contrast and compare this boy's phenotype to those of the classic connective tissue disorders. We conclude that he has cutis laxa with features that distinguish him from previously described types of cutis laxa. © 2003 Wiley‐Liss, Inc.
Chudley‐McCullough syndrome: Expanded phenotype and review of the literature
Authors: Welch Katherine Oelrich , Tekin Mustafa , Nance Walter E. , Blanton Susan H. , Arnos Kathleen S. , Pandya Arti 
Published: April 2003

AbstractChudley‐McCullough syndrome is an autosomal recessive condition characterized by profound sensorineural deafness, hydrocephalus secondary to obstruction of the foramen of Monro, and other structural abnormalities of the brain. We describe a family including two brothers and a sister with this condition. Each has profound sensorineural deafness that was either congenital or rapidly progressive in infancy and asymmetric dilatation of the lateral ventricles secondary to obstruction of the foramen of Monro. They also have additional brain abnormalities, including arachnoid cyst, partial agenesis of the corpus callosum, and abnormalities in the migration of cerebellar cells. This report is the fourth description of this condition within four years, suggesting Chudley‐McCullough may not be as rare as once assumed. We, therefore, recommend an audiological assessment for all children with hydrocephalus, especially those with obstruction of the foramen of Monro. © 2003 Wiley‐Liss, Inc.
Professional opportunities and responsibilities in the provision of genetic information to children relinquished for adoption
Authors: Venne Vickie L. , Botkin Jeffrey R. , Buys Saundra S. 
Published: April 2003

AbstractWe report a case involving the disclosure of BRCA1 mutation results to a woman who had placed a child for adoption 30 years prior to learning her mutation status. The disclosure of the mother's genetic test result to the son resulted in unexpected subsequent communications. This article briefly describes the experience and discusses the unique issues that arise in counseling a parent who has relinquished a child who is subsequently at risk to inherit a mutation for an adult onset genetic condition. © 2003 Wiley‐Liss, Inc.
Familial mitral valve prolapse associated with short stature, characteristic face, and sudden death
Authors: James Paul A. , Aftimos Salim , Skinner Jonathan R. 
Published: April 2003

AbstractMitral valve prolapse (MVP) is frequently a familial disorder but in few of these inherited cases it does form a prominent component of a multiple congenital anomaly (MCA) syndrome. We report a family in which eight individuals in four generations were affected by a dominantly inherited disorder involving MVP, short stature, a dolicocephalic face, broad forehead, posteriorly angulated ears, long philtrum, thin upper lip, high arched palate, and a small mandible. The proband presented with infective mastoiditis, bacterial endocarditis, and a supraventricular tachycardia. One other family member also had infective mastoiditis and bacterial endocarditis and both the proband's mother and grandmother died suddenly at the age of 30 and 25 years, respectively. © 2003 Wiley‐Liss, Inc.
No association between single nucleotide polymorphisms in DLX6 and piccolo genes at 7q21‐q22 and autism
Authors: Nabi Rafiqun , Zhong Hailang , Serajee Fatema J , Huq AHM Mahbubul 
Published: April 2003

AbstractSeveral independent genome scans have revealed excess allele sharing in an overlapping 40 cM region of 7q21‐34 in autism. DLX6 and Piccolo (PCLO) at 7q21‐q22 are two positional and functional candidate genes in autism. We have investigated a single nucleotide polymorphism (SNP) in exon 4 of the PCLO gene and a SNP in intron 1 of the DLX6 gene for linkage and association in autistic disorder using both qualitative and quantitative analyses. One hundred ninety‐six multiplex autistic disorder families were tested using transmission disequilibrium and two‐point affected sib pair linkage analysis. We found no evidence of association or linkage with the two intragenic markers. In addition, there was also no linkage or association between language and stereotypic behavior quantitative traits in autism and the SNPs. In conclusion, our studies suggest that these two SNPs in DLX6 and PCLO genes are not in linkage disequilibrium with autism. © 2003 Wiley‐Liss, Inc.

Published: April 2003

AbstractMutations in MECP2 gene account for approximately 80% of cases of Rett syndrome (RTT), an X‐linked severe developmental disorder affecting young girls, as well as for most cases of Preserved Speech Variant (PSV), a mild RTT variant in which autistic behavior is common. The aim of this study is to determine whether MECP2 mutations are responsible for PSV only or may cause other forms of autistic disorders. We screened for mutations by SSCP 19 girls with a clinical diagnosis of autism, two of them fulfilling the PSV criteria. A pathogenic mutation was found only in the latter two cases (R133C and R453X). A long follow‐up of these two girls revealed a unique clinical course. They initially developed the first three stages of RTT, they were severely retarded and had autistic behavior. Over the years their abilities increased progressively and by early adolescence they lost autistic behavior, becoming adequately accustomed to people and reaching an IQ close to 45. These results confirm previous clinical studies suggesting that a wide spectrum of RTT exists including girls with mental abilities considerably higher than in classic RTT. We conclude that MECP2 mutations (missense or late truncating) can be found in girls with an IQ close to 45 and a clinical history of PSV of Rett syndrome. Furthermore, MECP2 mutations are not found in patients in which autism remains stable over the years. © 2003 Wiley‐Liss, Inc.
Evaluation of the genes for the adrenergic receptors α2A and α1C and Gilles de la Tourette Syndrome
Authors: Xu Chun , Ozbay Fatih , Wigg Karen , Shulman Rayzie , Tahir Eda , Yazgan Yanki , Sandor Paul , Barr Cathy L. 
Published: April 2003

AbstractGilles de la Tourette Syndrome (GTS) has long been known to be familial, and evidence from twin studies indicates that it has a substantial genetic component. Our genome scan of sibling pair families with GTS found evidence suggestive of linkage to several chromosomal locations. On the basis of these findings, we have begun to study additional markers in these regions, with some of the markers located in candidate genes. Two candidate genes stand out in these regions: the adrenergic receptor α1C(1A) (ADRA1C) located on chromosome 8p and the adrenergic receptor α2A (ADRA2A) located on chromosome 10q. The adrenergic system has been suggested to play a role in GTS based on the reduction of symptoms with the adrenergic receptor agonists, clonidine and guanfacine. We examined the inheritance of polymorphisms in the ADRA2A and ADRA1C genes in 113 nuclear families identified through a GTS proband. We found no significant evidence for linkage using the transmission disequilibrium test for these two genes. Based on our families, we conclude that these genes are not major genetic factors contributing to the susceptibility to GTS. © 2003 Wiley‐Liss, Inc.
Dopamine D2 receptor gene Ser311Cys variant and schizophrenia: association study and meta‐analysis

Published: April 2003

AbstractAn association has been reported between a dopamine D2 receptor gene (DRD2) Ser311Cys variant and schizophrenia. In a replication attempt, Swedish patients with schizophrenia (n = 173) and control subjects (n = 236) were assessed for the DRD2 Ser311Cys variant. Schizophrenic patients displayed higher Cys311 allele frequencies than control subjects (4.0 vs. 0.8%, χ2 = 9.49, df = 1, P = 0.002; odds ratio (OR) 4.93, 95% confidence interval (95% CI) 1.61–15.12). The association was detected only in men. The results were supported by a meta‐analysis of all published case–control studies comprising a total of 9,152 subjects (χ2 = 11.37, df = 1, P < 0.001; OR 1.43, 95% CI 1.16–1.78). The present results support the involvement of the DRD2 gene in the pathogenesis of schizophrenia. © 2003 Wiley‐Liss, Inc.
Association of the dopamine beta hydroxylase gene with attention deficit hyperactivity disorder: Genetic analysis of the Milwaukee longitudinal study

Published: April 2003

AbstractAttention deficit hyperactivity disorder (ADHD) is a highly heritable and common disorder that partly reflects disturbed dopaminergic function in the brain. Recent genetic studies have shown that candidate genes involved in dopamine signaling and metabolism contribute to ADHD susceptibility. We have initiated genetic studies in a unique cohort of 158 ADHD and 81 control adult subjects who have been followed longitudinally since childhood in the Milwaukee study of ADHD. From this cohort, genetic analysis was performed in 105 Caucasian subjects with ADHD and 68 age and ethnicity‐matched controls for the DRD4 exon 3 VNTR, the SLC6A3 (DAT1) 3′ UTR VNTR, dopamine beta hydroxylase (DBH) TaqI A polymorphism, and the DBH GT microsatellite repeat polymorphism that has been quantitatively associated with serum levels of DBH activity, but not previously studied in ADHD. Results indicate a significant association between the DBH TaqI A1 allele and ADHD (P = 0.018) with a relative risk of 1.33. The DBH GT repeat 4 allele, which is associated with high serum levels of DBH, occurred more frequently in the ADHD group than controls, but the difference did not reach statistical significance. Associations were not found with the SLC6A3 10 repeat or DRD4 7 repeat alleles. These results indicate that the DBH TaqI A allele, or another polymorphism in linkage disequilibrium with this allele, may confer increased susceptibility towards ADHD. © 2003 Wiley‐Liss, Inc.
