Interstate 74 Quad Cities Corridor Study Scott County, Iowa and Rock Island County, Illinois Project Number IM-74-1(122)0-13-82 FHWA-IOWA-EIS-09-01-F, February 2009

The Federal Highway Administration (FHWA) and the Iowa and Illinois Departments of Transportation (Iowa DOT and IDOT) have identified the Selected Alternative for improving Interstate 74 (I-74) from its southern terminus at Avenue of the Cities (23rd Avenue) in Moline, Illinois to its northern terminus one mile north of the I-74 interchange with 53rd Street in Davenport, Iowa. The Selected Alternative identified and discussed in this Record of Decision is the preferred alternative identified in the Final Environmental Impact Statement (FEIS). The purpose of the proposed improvements is to improve capacity, travel reliability, and safety along I-74 between its termini, and provide consistency with local land use planning goals. The need for the proposed improvements to the I-74 corridor is based on a combination of factors related to providing better transportation service and sustaining economic development.

Concrete Overlay Field Application Program Iowa Task Report US 18 Concrete Overlay Construction Under Traffic, May 2012

The National Concrete Pavement Technology Center, Iowa Department of Transportation, and Federal Highway Administration set out to demonstrate and document the design and construction of portland cement concrete (PCC) overlays on two-lane roadways while maintaining two-way traffic. An 18.82 mile project was selected for 2011 construction in northeast Iowa on US 18 between Fredericksburg and West Union. This report documents planning, design, and construction of the project and lessons learned. The work included the addition of subdrains, full-depth patching, bridge approach replacement, and drainage structural repair and cleaning prior to overlay construction. The paving involved surface preparation by milling to grade and the placement of a 4.5 inch PCC overlay and 4 foot of widening to the existing pavement. In addition, the report makes recommendations on ways to improve the process for future concrete overlays.

Video analysis software increases the interrater reliability of video gait assessments in children with cerebral palsy.

The aim of this study was to determine the effect of using video analysis software on the interrater reliability of visual assessments of gait videos in children with cerebral palsy. Two clinicians viewed the same random selection of 20 sagittal and frontal video recordings of 12 children with cerebral palsy routinely acquired during outpatient rehabilitation clinics. Both observers rated these videos in a random sequence for each lower limb using the Observational Gait Scale, once with standard video software and another with video analysis software (Dartfish(®)) which can perform angle and timing measurements. The video analysis software improved interrater agreement, measured by weighted Cohen's kappas, for the total score (κ 0.778→0.809) and all of the items that required angle and/or timing measurements (knee position mid-stance κ 0.344→0.591; hindfoot position mid-stance κ 0.160→0.346; foot contact mid-stance κ 0.700→0.854; timing of heel rise κ 0.769→0.835). The use of video analysis software is an efficient approach to improve the reliability of visual video assessments.

Treatment of velopharyngeal insufficiency by autologous fat injection.

Velopharyngeal insufficiency (VPI) is a structural or functional trouble, which causes hypernasal speech. Velopharyngeal flaps, speech therapy and augmentation pharyngoplasty, using different implants, have all been used to address this trouble. We hereby present our results following rhinopharyngeal autologous fat injection in 18 patients with mild velopharyngeal insufficiency (12 soft palate clefts, 4 functional VPI, 2 myopathy). 28 injections were carried out between 2004 and 2007. The degree of hypernasal speech was evaluated pre- and postoperatively by a speech therapist and an ENT specialist and quantified by an acoustic nasometry (Kay Elemetrics). All patients were exhaustively treated with preoperative speech therapy (average, 8 years). The mean value of the nasalance score was 37% preoperatively and 23% postoperatively (p = 0.015). The hypernasality was reduced postoperatively in all patients (1-3 degrees of the Borel-Maisonny score). There were no major complications, two minor complications (one hematoma, one cervical pain). The autologous fat injection is a simple, safe, minimally invasive procedure. It proves to be efficient in cases of mild velopharyngeal insufficiency or after a suboptimal velopharyngoplasty.

Germ cell-specific targeting of DICER or DGCR8 reveals a novel role for endo-siRNAs in the progression of mammalian spermatogenesis and male fertility.

Small non-coding RNAs act as critical regulators of gene expression and are essential for male germ cell development and spermatogenesis. Previously, we showed that germ cell-specific inactivation of Dicer1, an endonuclease essential for the biogenesis of micro-RNAs (miRNAs) and endogenous small interfering RNAs (endo-siRNAs), led to complete male infertility due to alterations in meiotic progression, increased spermatocyte apoptosis and defects in the maturation of spermatozoa. To dissect the distinct physiological roles of miRNAs and endo-siRNAs in spermatogenesis, we compared the testicular phenotype of mice with Dicer1 or Dgcr8 depletion in male germ cells. Dgcr8 mutant mice, which have a defective miRNA pathway while retaining an intact endo-siRNA pathway, were also infertile and displayed similar defects, although less severe, to Dicer1 mutant mice. These included cumulative defects in meiotic and haploid phases of spermatogenesis, resulting in oligo-, terato-, and azoospermia. In addition, we found by RNA sequencing of purified spermatocytes that inactivation of Dicer1 and the resulting absence of miRNAs affected the fine tuning of protein-coding gene expression by increasing low level gene expression. Overall, these results emphasize the essential role of miRNAs in the progression of spermatogenesis, but also indicate a role for endo-siRNAs in this process.

Currículo, conhecimento e transmissão cultural: contribuições para uma teorização pedagógica contemporânea

O artigo examina os estudos contemporâneos sobre a constituição dos currículos escolares, bem como os processos de seleção dos conhecimentos a serem ensinados, buscando ponderar a relevância e a urgência de produzirmos uma reflexão crítica sobre os modos de transmissão cultural mobilizados nas diferentes cenas pedagógicas. Para tanto, inscreve essa problematização no âmbito dos estudos curriculares, indicando as maneiras pelas quais se atribui centralidade ao conceito de conhecimento escolar. Serão revisados três pensadores sociais do século XX: Émile Durkheim, Antonio Gramsci e Hannah Arendt. Em condições teóricas diferenciadas, partindo de pressupostos argumentativos divergentes, os pensadores assinalam a relevância social e política da tarefa da transmissão cultural na escola.
