Standardization for Defence Procurement - European Handbook : CEN Workshop 10

The European Commission (EC), DG Enterprise, endeavours the competitiveness of the European Defence Industry. The plethora of (national) standards, more than 10.000, are recognised by the EC as a major constraint and cost driver. Electromagnetic Compatibility (EMC) or Electromagnetic Environmental Effects (EEE) are considered by the EC as a major topic, with 7 other topics such as environmental engineering, energetic materials, batteries, electrical interfaces. An EMC expert group with representatives from industry, including Aerotech Telub, Intellect, EADS, Ericsson Microwave, Fincantieri, MBDA, Thales, and national MoDs rationalized in 2004 a list of 329 EEE standards, implicitly abandoning national, including American, standards, and develop guidelines for the procurement process. A limited number of widely accepted and cost effective standards, suitable for use by MoD’s (acquisition) and industry (product development), has been defined after making comparisons. Comparisons were carried out on some standards against STANAG 4370 AECTP 500. The Expert Group agreed; That no one standard is better or worse than another in achieving an end goal. Differences are not sufficient to prevent the use of AECTP 500. There are sufficient similarities to AECTP 500 to adopt this as the fundamental replacement standard. There was sufficient agreement on NATO-, IEC- and EN-produced standards to make worthwhile agreement to use a number of standards as replacement for some (or some parts) of existing National Standards. This document gives recommendations on the use of the standards, the scope and \ud limitations. It also emphasizes the constraints with respect to the standardisation process of National MoD’s, NATO, Industry and EN/IEC

Synergistic interaction effect between job control and social support at work on general psychological distress

Purpose Little is known about the interaction between job control and social support at work on common mental disorders. To examine whether there is a synergistic interaction effect between job control and social support at work on general psychological distress and whether it differs by the level of job demands. Methods About 1,940 male and female workers from the Malmo Shoulder and Neck Study were chosen for this cross-sectional study. Job control, social support at work, and job demands were measured by the Swedish version of the Job Content Questionnaire, and general psychological distress was assessed by the General Health Questionnaire. Results A significant excessive risk increase for general psychological distress was observed when workers had both low job control and low social support at work in both men and women. The synergistic effect was stronger in women, when job demands were low (Rothman's synergy index was 2.16 vs. 1.51 when job demands were high). However, in male workers, while a strong synergistic effect between job control and social support at work was found when job demands were low (synergy index was 9.25), there was an antagonistic effect when job demands were high (synergy index was 0.52). Conclusions There was a synergistic interaction effect between job control and social support at work on general psychological distress, but the synergistic effect or its effect size differed by the level of job demands and gender. An atomic, additive approach to the risk assessment of the psychosocial work characteristics on common mental disorders could be misleading or lead to a risk underestimation

Developing otitis media : experimental studies in particular regarding inflammatory changes in the tympanic membrane

Otitis media (OM), one of the commonest of childhood diseases, causes much suffering. OM exists in a variety of forms, two of which are acute otitis media (AOM) and otitis media with effusion (OME). The clinical courses of these conditions differ, AOM usually presenting with earache, fever and/or aural discharge, and the OME usually with hearing impairment. The tympanic membrane (TM) mirrors the events in the middle ear cavity, and pars flaccida (PF) is the initial site of inflammatory changes in the TM. PF is rich in mast cells (MCs), which by releasing various mediators, may trigger TM inflammation. The aims of the present studies were to investigate early inflammatory changes in the TM in rat models of OM; after mast cell degranulation, in response to AOM, and OME, after myringotomy in AOM and in normal ears. Furthermore, we developed a new rat AOM model, that excludes surgical trauma and resembles the natural route of infection in man. AOM and OME elicited the first inflammatory response in PF of the TM. The response to OME was discrete, but a slight increase in macrophages was found. During the first 48 hours of AOM, the inflammatory response was intense, following a bimodal pattern. This reaction is similar to that found after MC degranulation. In AOM, macrophages were the predominant cell in PF, while in pars tensa (PT), polymorphonuclear cells (mainly neutrophils) predominated. When myringotomy was performed in AOM ears, the healing time was shorter than that of myringotomy in normal ears. The highly inflamed lamina propria seemed to promote healing. During early AOM, as well as following myringotomy, fibrin extravasates into PF and PT. This fibrin deposition may be involved in regulating the inflammatory response. Repeated nasal challenge with the otitis media pathogen Streptococcus pneumoniae provoked AOM and concomitant TM stimulation reduced the number of AOM cases. This new rat AOM model has the advantage of avoiding trauma in the middle ear cavity, while eliciting an intense inflammatory response in the middle ear cavity (MEC)

Mot en professionalisering av det pedagogiska ledarskapet vid Umeå universitet

Det pedagogiska ledarskapet inom högre utbildning fokuseras allt mer. Det understryks genom att flera lärosäten föreskriver såväl att pedagogiska ledare ska finnas på olika nivåer, som vilka övergripande uppgifter dessa ska ha. Denna artikel är ett resultat av en fallstudie av hur de tillägnade kunskaperna och färdigheterna från kursen Pedagogiskt ledarskap, en kurs för målgruppen studierektorer/pedagogiskt ansvariga eller motsvarande arrangerad av Universitetspedagogiskt centrum, har bidragit till deltagarnas professionalisering av det pedagogiska ledarskapet ett år efter kursens slut. Fallstudien genomfördes genom gruppintervjuer. Respondenterna uttryckte att de fått ett stärkt självförtroende i rollen som pedagogiska ledare samt att kursen bidrog till en professionalisering av rollen som pedagogiska ledare genom att stärka identiteten, att skapa en början till en handlingsetik bestående av delvis delade värderingar kring det pedagogiska ansvaret samt ge utbildning och träning i färdigheter som har sin grund i teoretisk kunskap. Kursen Pedagogiskt ledarskap ger därmed ett stöd i en process mot en professionalisering av det pedagogiska ledarskapet vid Umeå universitet

Frequency, Diagnosis, Treatment, and Outcome of Gastrointestinal Disease in Granulomatosis with Polyangiitis and Microscopic Polyangiitis

Objective. Involvement of the gastrointestinal (GI) tract is a rare complication of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). The aim was to describe frequency, diagnosis, treatment, and outcome of GI disease in a large series of patients in a single center. Methods. A database that includes all patients with GPA and MPA diagnosed since 1997 in a defined area of southeastern Sweden as well as prevalent older cases and tertiary referral patients was screened for patients with GI disease. Data were retrieved from the patients medical records, and GI manifestations of vasculitis were defined as proposed by Pagnoux, et al in 2005. Results. Fourteen (6.5%) of 216 consecutive patients with GPA/MPA had GI manifestations. Abdominal pain and GI bleeding were the most common symptoms. Radiology was important for detection of GI disease, while endoscopy failed to support the diagnosis in many patients. Because of perforation, 5 patients underwent hemicolectomy or small intestine resection. Primary anastomosis was created in 2/5 and enterostomy in 3/5 patients. One patient had a hemicolectomy because of lower GI bleeding. One sigmoid abscess was treated with drainage, and 1 intraabdominal bleeding condition with arterial coiling. Two patients died from GI disease. GPA and MPA patients with and without GI disease exhibited a similar overall survival. Conclusion. GI disease was found in 6.5% among 216 patients with GPA or MPA. Surgery was judged necessary only in cases with GI perforation or severe bleeding. Multidisciplinary engagement is strongly recommended
