Food waste perceptions and reported behaviours during the first wave of the COVID-19 pandemic: Evidence from Bosnia and Herzegovina

An increasing corpus of data demonstrated the disruptive impacts of the COVID-19 pandemic on food consumption habits, particularly food waste, but the Balkan area is often overlooked. Accordingly, this study investigates the immediate effects of the COVID-19 pandemic on consumer knowledge and reported behaviours linked to food waste in Bosnia and Herzegovina. The research was based on an online survey with 2425 participants using the Google forms platform from 10 April to 10 May 2020. This period coincided with the first wave of the COVID-19 pandemic in Bosnia and Herzegovina. Consumers' behaviours regarding where and how often they buy food, their attitude towards food labels, food provision and particularly the amounts and values of food waste and how they handle it were investigated. The data were analysed using descriptive statistics methods, and the significance of the association between variables was determined using nonparametric and multivariate statistical tests. The study's findings revealed that (i) Bosnia has a low rate of household food waste and a favourable attitude towards food waste prevention, (ii) the majority of the respondents are familiar with the most common expiry labels, notably 'use by' and 'best before' and (iii) consumers adjusted their buying and consumption patterns due to the pandemic. The findings of this research are essential for developing evidence-based policy in Bosnia and Herzegovina during the post-pandemic recovery period since they are unique to that country. Indeed, the crisis' lessons and insights may be used to help move towards more sustainable consumption habits.

Observations on Food Consumption Behaviors During the COVID-19 Pandemic in Oman

This paper aims to study the perceptions of the impacts of the COVID-19 pandemic on behaviors related to diet and food shopping on a sample of 356 adults in Oman. The study is based on the results of an Arabic-language online survey conducted between September 15 and October 10, 2020, using the Survey Monkey platform. The questionnaire had 25 questions (multiple options and one option), subdivided into three parts. Respondents were asked to disseminate the survey to their networks as part of the study's snowball sampling method. Descriptive statistics and various statistical tests (e.g., U-Mann Whitney, Kruskal-Wallis, chi-square) have been used to evaluate the study results. The study showed a significant shift in the attitude and behavior of respondents regarding food and health. Indeed, the paper findings indicated (i) a shift to healthier diets, as shown by the fact that 45.5% of the participants increased their intake of fruits and vegetables, 42.4% ate more healthy foods, and 53.1% reduced their intake of unhealthy foods; (ii) an increase in the consumption of local products, owing to food safety concerns, with 25.8% of the cohort stating that they purchase more local food items; (iii) a shift in grocery shopping behaviors, especially with 28.1% of the participants buying more groceries online; (iv) the absence of panic buying in Oman, since 62.36% of the participants said they did not stockpile food items; and (v) a reduction of food waste. Indeed, 78.9% of the participants specified they were not wasting more food than average since the beginning of the pandemic, and 74.72% indicated they were more aware of how much food they were wasting. Surprisingly, COVID-19 appears to bring many beneficial adjustments in Oman to make food consumption more sustainable and healthier.

Significance of Biological Membranes for Accurate Computational Dosimetry of Low Frequency Electric Fields

Computational dosimetry has become the main tool for estimating induced electric fields within brain tissues in transcranial direct current stimulation (tDCS) which is recently attracting the attention of researches for motor function disturbances such as Parkinson's disease. This paper investigates the effect of including or excluding the very thin meninges in computing tDCS electric fields using CST software. For this purpose, two models of the brain with and without meninges were used to induce electric field with two DC current electrodes (2 mA) in regions of the model referring to M1 and Prefrontal Cortex (FP2) similar to tDCS. Considering meninges, the results have shown differences in the induced field showing that there might be problems with conventional models in which meninges are not taken into account.

Expanded occipito-cervico-pectoral flap for reconstruction of burned cervical contracture

Postburn neck contracture and hypertrophic scarring can cause functional limitation and aesthetic disfigurement. Reconstruction of severe deformities and scar of neck following healing from burns confronts the surgeon with some of the most challenging problems in reconstructive surgery. Through knowledge of available reconstructive technique accurate diagnosis of tissue deficiency and secondary distortion, imaginative planning and definitive, careful execution of ones surgical plan are the bare minimum items for achieving improvement in a burned deformed neck. The aim of this article is to assess the role of expanded occipito-cervico-pectoral (o-c-p) flap for reconstruction in a series of four patients with severe burn scar of neck and involvement of shoulder back but intact anterior aspect of chest. This is an alternative method of reconstruction burn scar of neck area.
