Nudging and other behaviourally based policies as enablers for environmental sustainability

Recent years have shown that traditional regulatory techniques alone are not effective in achieving behaviour change in important fields such as environmental sustainability. Governments all over the world have been progressively including behaviourally informed considerations in policy and law making with the aim of improving the acceptance and impact of sustainability-oriented measures. This led to the arrival of alternative regulatory tools, such as nudges. The effectiveness of nudges for environmental sustainability (green nudges) has been widely reported, but the practical and ethical implications are still largely neglected by academic research. In this contribution, “nudges” are conceptually distinguished from “boosts” and their ethics are briefly explained. The analysis is made in light of European and US American academic literature

A structural magnetic resonance imaging study in therapy-naïve transsexual individuals

Background: Transsexuality is explained and defined as a gender-identity disorder, characterised by very strong conviction of belonging to the opposite sex and has been associated with a distinct neuroanatomical pattern. Materials and methods: We performed a structural analysis in search of possible differences in grey matter structures based on magnetic resonance imaging scans of the brains of 26 individuals between 19 and 38 years of age. The participants were divided into two groups of 15 controls and 11 transgender individuals. The segmentation of subcortical grey matter was performed using FIRST model a model-based segmentation/registration tool, from FSL software package. Results: The results showed that the volume of the brain region called nucleus accumbens on the left side was significantly smaller in the group of transgender individuals compared to the control. It was the most important parameter which was shown to make distinction between two examined groups. Conclusions: The results also showed decreased volumes of the left thalamus, right hippocampus and right caudate nucleus

Assessment of the periodontal health and community periodontal index in the Army of Serbia

Promotion of oral health in military population is not only a significant component of general health, but also of the military readiness and represents the strategic orientation of each country. The basic task of military dentistry is to provide oral health of military personnel and to enable their operational readiness at the optimal level. The aim of the study was to assess the periodontal condition in Serbian military population using the community periodontal index of treatment needs (CPITN), and the influence of general life habits and local risk factors on periodontal health. Methods. This prospective cross-sectional pilot study was conducted on 101 examinees at the mean age of 38.94 ± 11.63 years who had dental check-ups at the Dental Clinic of the Military Medical Academy in Belgrade. All the categories of military personnel aged 20–64 years were divided into five groups. The frequency distribution of general and local factors on periodontal health, oral hygiene index, and the assessment of the mean number of sextants by CPITN compared to age were examined. Results. The examinees at the age of 51–60 years had the best oral hygiene index (0.95 ± 0.65), whereas the oldest population had the worst (1.63 ± 0.42). Only one person (5.6%) at the age group of 51–60 years had a completely healthy periodontium. Observed in relation to the age groups, the mean values of sextants increased linearly, but in general population, the most frequent CPITN categories were in sextant with the periodontal pockets 4–5 mm (score 3). Conclusions. Compared to the results from other countries shown by the World Health Organization, the periodontal condition in our examinees is below the average. The appropriate preventive program preparation and its implementation are needed, including primarily the appropriate training on oral hygiene, as well as education based on periodontal disease prevention and treatment
