AbstractStarting from the observation that questionnaires for appropriately measuring the changing working conditions and requirements of the highly qualified workforce do not exist, we developed a new German-language instrument focussing on knowledge work. Based on theoretical considerations, we first identified three basic dimensions that constitute knowledge work: novelty, complexity, and autonomy. During the subsequent process of questionnaire development with higher education graduates, including a cognitive pretest, a quantitative development study, and a replication study, these dimensions were operationalised by initially 173 and finally 22 items. Confirmatory factor analysis and structural equation modelling of the data of both the development and the replication study show that the 22-item instrument validly and reliably measures novelty (4 items), complexity with three subdimensions (9 items), and autonomy, also with three subdimensions (9 items). An English version of the questionnaire is available. However, the empirical test of the English-language questionnaire as well as possible refinements of the measurement instrument, which will be discussed in the final section of the paper, are left to future research.

Abstract Background Patient-centered care is an essential component of health care quality. To achieve patient-centered care, health care authorities should have a clear definition and an applicable tool to measure the extent of its application. The real concept of patient centeredness should be developed by the patients themselves. We aimed to demonstrate a way to develop a draft Arabic patient-centered infertility care (PCIC) questionnaire for females clients following practical steps that address women with infertility. Methods An iterative process of questionnaire development was undertaken by combining two approaches: the steps proposed by Robert F. DeVellis for scale development and the recommended practices for questionnaire development and testing in the European statistical system. We attempted to develop the draft questionnaire that involved conceptualization and operationalization, generation of an item pool, development of the questionnaire format, review of the initial item pool by experts, and consideration of validation items for inclusion. Results We generated an item pool from in-depth interviews with 14 women who sought infertility care within 6 months before the interview time. We then added more items from a literature review. The item pool contained 123 items distributed through 10 domains. Ten women with infertility were included for face validation. Then, experts with backgrounds in Obstetrics and Gynecology, Family Medicine, and Public Health reviewed the item pool using content validation (n = 10 professors and/or specialists). The item pool was finally reduced to 57 items. We developed the draft Arabic patient-centered infertility care questionnaire for female clients (PCIQ-F) with three sections, including 66 items: background variables, PCIC experience variables, and a general question about the quality of infertility care in the health facility. The draft questionnaire was further reviewed and edited last by experts in preparation for part 2, which will test the questionnaire and prepare the final version. Conclusion The PCIQ-F questionnaire development is a multi-step iterative process started and ended by the target users as experts. Experts’ participation in infertility care and in questionnaire format development had a great impact on questionnaire development and conflict resolution. We recommend this transparent and replicable approach for new instrument developers; it is likely to generate a questionnaire that is valid and acceptable to target users. The draft PCIQ-F questionnaire is ready for testing of its psychometric properties before the final version to measure the PCIC level in health facilities.

A New High Excitation Objective Lens (Second-Zone Objective Lens) was discussed at Twenty-Sixth Annual EMSA Meeting. A new commercially available Transmission Electron Microscope incorporating this new lens has been completed.Major advantages of the new instrument allow an extremely small beam to be produced on the specimen plane which minimizes specimen beam damages, reduces contamination and drift.

The current imaging trend in optical microscopy, scanning electron microscopy (SEM) or transmission electron microscopy (TEM) is to record all data digitally. Most manufacturers currently market digital acquisition systems with their microscope packages. The advantages of digital acquisition include: almost instant viewing of the data as a high-quaity positive image (a major benefit when compared to TEM images recorded onto film, where one must wait until after the microscope session to develop the images); the ability to readily quantify features in the images and measure intensities; and extremely compact storage (removable 5.25” storage devices which now can hold up to several gigabytes of data).The problem for many researchers, however, is that they have perfectly serviceable microscopes that they routinely use that have no digital imaging capabilities with little hope of purchasing a new instrument.
