The description and analysis of animal behavior over long periods of time is one of the most important challenges in ecology. However, most of these studies are limited due to the time and cost required by human observers. The collection of data via video recordings allows observation periods to be extended. However, their evaluation by human observers is very time-consuming. Progress in automated evaluation, using suitable deep learning methods, seems to be a forward-looking approach to...

Abstract Society is currently facing an unprecedented challenge in terms of achieving food and nutrition security for a rapidly expanding global population while also minimising and reversing damage to the natural environment. Compounding this issue is climate change, which adversely affects the four pillars of food security: availability, access, utilisation and stability. This study aims to quantify the potential impact of future climate and societal change on food and nutrition security...

Nigeria is reported as having released up to 0.34 million tonnes of plastic debris into the ocean in 2010 and ranked as the ninth country in the world for pollution of the marine environment. It is a postcolonial, oil rich country where plastic is cheap and widely available. Currently there is no government policy regulating single-use plastic products. Previous studies have identified university student residential areas as ‘hot spots’ for plastic waste. We used qualitative methods (focus...

The inclusive education movement generated many changes in the education system worldwide, resulting in teachers needing to change their practice and beliefs and implement inclusive teaching strategies to accommodate a more diverse learner population. Numerous professional development courses were conducted in South Africa, however the expected change in attitude and practice proved difficult to achieve for many. Even after attending such courses, teachers found it challenging to establish...

The aim of this paper is to investigate how working conditions in early childhood development education centres impact on teacher performance in Kenya. The study employed descriptive survey design. The target population involved 98 ECDE teachers who were selected using simple random sampling, stratified and purposive sampling techniques. The sample size 80 pre-primary teachers from three wards; Kapsoya, Kaptagat and Ainabkoi/Olare divisions. Questionnaires were used to collect data from head...

Abstract. Seismic arrays provide tools for the localization of events without clear phases or events outside of the network, where the station coverage prohibits classical localization techniques. Beamforming allows the determination of the direction (backazimuth) and the horizontal (apparent) velocity of an incoming wavefront. Here we combine multiple arrays to retrieve event epicenters from the area of intersecting beams without the need to specify a velocity model. The analysis is...

Executive remuneration is defined as compensation for achieving the agreed target . Executive compensation consists of base or fixed pay and variable pay. Base pay is mainly determined by market data (i.e. organisational size, labour market/industry/sector and geographical location), while variable pay is linked to performance . Corporate executives' variable pay entails bonuses and shares, and its contributors are given more weight than those for the base pay. This means that corporate...

This mixed methods study explored grit and well-being among South African first-year university students (N = 405, female = 57.10%; mean age = 20.59, SD = 1.65 years). The students self-reported their grit and well-being. A small subsample of the students (n = 18, females = 61%) completed individual interviews on how their sense of grit related to their subjective well-being. Regression analysis indicated higher self-reported grit scores predicted higher well-being. Thematic analysis of the...
