Raising the Revenue at a Small-Circulation Magazine: Geist Magazine Pursues National Advertisers
This paper is based on research I conducted during the internship I d ~ d at Geist in the summer of 2004. As directed by Craig hggs for Geist, I worked on various special projects related to the magazine\u27s pursuit of national advertisers. This project report explores why this is an opportune time for Geist to pursue national advertisers, as well as the challenges and opportunities the magazine faces. It outlines what makes a magazine a desirable medium for advertisers. It delves into the relationship between small magazines and their readers. It describes two ways in which advertising can appear in magazines: &splay advertising and corporate sponsorship. The project report also explains the steps Geist has taken and is taking in its pursuit of national advertisers: readership surveys and external evaluations in the form of Print Measurement Bureau analysis and a circulation audt
Mettre en Ćuvre pour la premiĂšre fois la dĂ©marche d'investigation avec des Ă©lĂšves de CE2 : une sĂ©quence sur les conditions de germination d'une graine
Au cours d'un stage en pratique accompagnĂ©e, nous avons mis en Ćuvre la dĂ©marche d'investigation avec une classe de CE2, lors d'une sĂ©quence sur les conditions de germination d'une graine. Il s'agissait d'une dĂ©couverte, tant pour les Ă©lĂšves que pour nous. Notre objectif Ă©tait, au-delĂ de l'acquisition de connaissances, de permettre aux Ă©lĂšves de comprendre cette dĂ©marche scientifique et de se l'approprier. Nous pensions que par sa seule mise en Ćuvre nous atteindrions ce but. Il ressort de l'analyse des rĂ©sultats et de notre pratique qu'il n'est pas suffisant de faire vivre la dĂ©marche d'investigation aux Ă©lĂšves pour qu'ils la comprennent et se l'approprient, et a fortiori la premiĂšre fois. Un fort Ă©tayage est nĂ©cessaire, afin de baliser chacune des Ă©tapes et les rendre porteuses de sens pour les Ă©lĂšves
Stressful events in early childhood and developmental trajectories of bedwetting at school age
Objective To examine whether early stressful events are associated with developmental trajectories of bedwetting.âMethodsâThis is a prospective cohort study comprising 8,761 participants from the Avon Longitudinal Study of Parents and Children. Stressful events were measured using a maternal questionnaire completed at 3 time points before their child was 4 years old. The association between stressful events and trajectories of bedwetting from 4 to 9 years was examined using multinomial regression.âResultsâThe association with stressful events was strongest for the frequent persistent bedwetting trajectory (wetting at least twice a week up to age 9). A 1 standard deviation increase in the stressful events score was associated with a 29% (13â47%) increase in the odds of experiencing frequent persistent bedwetting compared with normal attainment of nighttime bladder control.âConclusionsâClinicians and parents should be aware that continence is a developmental outcome that is associated with high levels of stress in the family
Developing a Macroscopic Mechanistic Model for Low Molecular Weight Diffusion through Polymers in the Rubbery State
Raman microspectroscopy was used to determine the Fickian diffusivity of two families of low molecular weight molecules through amorphous polystyrene in the rubbery state. Different effects of the temperature on diffusivity for each of the families suggested that molecular mobility is controlled by both the volume and flexibility of the diffusing substance when the movement of polymer chains can generate stress induced deformation of molecules. The diffusing molecules were represented as Newtonian spring-bead systems, which allowed us to quantify their flexibility, in function of the vibration frequency of their bonds by reconstructing their theoretical spectra. Results showed that the use of molecular descriptors that take into account flexibility rather than the most stable conformation of the diffusing molecules may improve the description of the diffusion behavior caused by variations in shape and size of the free volumes of the polymeric matrix in the rubbery state
Incontinence and psychological symptoms in Phelan-McDermid syndrome
Aims
Phelan-McDermid syndrome (PMD) is a congenital syndrome caused by a deletion on chromosome 22q13.3. About 600 cases have been identified worldwide. PMD is characterized by neonatal hypotonia, moderate/severe intellectual impairment, impaired expressive language, and typical dysmorphic features. Psychological symptoms as hyperactivity, attention problems, restlessness, and stereotyped-repetitive behavior were reported. The aim of the study was to assess incontinence and associated psychological problems in PMD.
Methods
Forty-one individuals with PMD were recruited through a German support group (48.8% male; mean age 13.4 years; range, 4-55 years). Parents or caregivers completed the developmental behavior checklist (DBC), as well as the parental questionnaire: enuresis/urinary incontinence, including six questions on adaptive toileting skills.
Results
Rates of nocturnal enuresis (NE), daytime urinary incontinence, and fecal incontinence were 86%, 73%, and 79%. Rates were similar in all age groups (children, teens, adults). Constipation was present in 19%. Forty-two percent of the sample had a clinically relevant DBC score, with adults more affected than teens. Persons with NE had significantly higher âanxiety/depressionâ subscale scores. Toileting skills were more developed in adults than in children. Sixty-eight percent had further physical disabilities.
Conclusions
Incontinence rates in PMD are high in all age groups. However, persons with PMD can improve their toilet skills. Therefore, the assessment and treatment of incontinence in persons with PMD is recommended. Constipation does not seem to be a major problem in PMD. Due to the high prevalence rates of somatic conditions, an assessment for organic and functional incontinence is recommended
Effect of HP/T treatments of in-package food on additive migration from conventional and bio-sourced materials
Correspondance: [email protected] audienceMigration was assessed during and after two HP/T treatments intended to perform a pasteurization (800 MPa for 5 min, from 20 to 40 °C) and a sterilization treatment (800 MPa for 5 min, from 90 to 115 °C) and were compared to conventional pasteurization and sterilization respectively. The specific migration of actual packaging additives used as antioxidants and UV absorbers (Irganox 1076, Uvitex OB) was investigated in a number of food-packaging system combining one synthetic common packaging (LLDPE) and a bio-sourced one (PLA) in contact with the four food simulating liquids defined by EC regulations. After standard HP/T processing, migration kinetics was followed during service life of package material using FTIR spectroscopy. LLDPE withstood the HP sterilization whereas it melted during the conventional sterilization. No difference was observed on migration from LLDPE for both treatments. In the case of PLA, migration of Uvitex OB was very low or no detectable for all the studied cases
