This paper presents the results of a survey which aimed at exploring the perceptions of the employees of a large aviation organization regarding the punitive or preventive character of possible measures that management could take in cases of errors and violations. The analysis of the quantitative and qualitative data collected showed that the viewpoints of the staff were sufficiently aligned only for half of the measures and that all measures inflicting a short- or long-term dissociation of the end-users from their current working place and function were highly unfavourable and linked to castigation. Also, statistically significant differences were observed across groups of specialties and years of service regarding the appropriateness of specific measures especially in the case of errors. The findings of this study in combination with literature references, suggest that the establishment of a just culture structure with agreed lines between the punitive and preventive character of measures and its endorsement by the employees is achievable, but it requires a bottom-up approach and periodical revision. Similar exploratory research, complemented possibly by explanatory studies, is recommended to be carried out by organizations prior or during the development of their just culture policy andrelated measures.
Background To gain insight into the role of plantar intrinsic foot muscles in fall-related gait parameters in older adults, it is fundamental to assess foot muscles separately. Ultrasonography is considered a promising instrument to quantify the strength capacity of individual muscles by assessing their morphology. The main goal of this study was to investigate the intra-assessor reliability and measurement error for ultrasound measures for the morphology of selected foot muscles and the plantar fascia in older adults using a tablet-based device. The secondary aim was to compare the measurement error between older and younger adults and between two different ultrasound machines. Methods Ultrasound images of selected foot muscles and the plantar fascia were collected in younger and older adults by a single operator, intensively trained in scanning the foot muscles, on two occasions, 1–8 days apart, using a tablet-based and a mainframe system. The intra-assessor reliability and standard error of measurement for the cross-sectional area and/or thickness were assessed by analysis of variance. The error variance was statistically compared across age groups and machines. Results Eighteen physically active older adults (mean age 73.8 (SD: 4.9) years) and ten younger adults (mean age 21.9 (SD: 1.8) years) participated in the study. In older adults, the standard error of measurement ranged from 2.8 to 11.9%. The ICC ranged from 0.57 to 0.97, but was excellent in most cases. The error variance for six morphology measures was statistically smaller in younger adults, but was small in older adults as well. When different error variances were observed across machines, overall, the tablet-based device showed superior repeatability. Conclusions This intra-assessor reliability study showed that a tablet-based ultrasound machine can be reliably used to assess the morphology of selected foot muscles in older adults, with the exception of plantar fascia thickness. Although the measurement errors were sometimes smaller in younger adults, they seem adequate in older adults to detect group mean hypertrophy as a response to training. A tablet-based ultrasound device seems to be a reliable alternative to a mainframe system. This advocates its use when foot muscle morphology in older adults is of interest.

Develop a maturity model based on a quick scan to see how far a (SME) company is in awareness / activities on sustainable logistics (and the direction to zero emission city logistics: ZECL ) and (if it is possible, because this is a 2nd model) how far governments are in their ZE zone planning. Based on the quick scan, companies receive appropriate information about their relevant policy and sustainability measures (including availability of e-vehicles, etc.). Tool can be used by students to quickly reach companies around ZECL and to provide them with information directly via the results. This helps and students learn about this subject, but should also contribute to awareness among a larger group of feeding/receiving and possibly loading parties about ZECL. In addition, with sufficiently participating companies, a good picture can also arise of how far companies are now with regard to ZECL (and this could also be repeated over time in order to get a picture of the development in maturity in this area).
