TL;DR: The authors found that the importance of teamwork, being given responsibility, and collaborative learning emerged as the most important factors for effective learning in the three contexts under consideration, while graduates recognized the contribution university had made to their generic skills development.
Abstract: This paper presents findings from Stage 4 of the Griffith Graduate Project. Graduates from three Schools within Griffith University were surveyed to determine their perceptions of the contributions that the learning contexts of university, work placement and post‐graduation employment made to the development of their generic skills. All graduates involved in the project had experienced work placement as a formal part of their undergraduate studies. Supplementary data from focus group discussions held with employers and graduates are also included. Findings showed that while graduates recognized the contribution university had made to their generic skills development, they greatly valued the experience of learning in the workplace during placement and subsequently in employment. The importance of teamwork, being given responsibility, and collaborative learning emerged as the most important factors for effective learning in the three contexts under consideration.

TL;DR: It is shown that Antarctic krill digest micro plastics into nano plastics, thereby generating particles of a size that can cross biological and physical barriers, and suggest that current laboratory-based feeding studies may be oversimplifying interactions between zooplankton and microplastics.
Abstract: Microplastics (plastics <5 mm diameter) are at the forefront of current environmental pollution research, however, little is known about the degradation of microplastics through ingestion. Here, by exposing Antarctic krill (Euphausia superba) to microplastics under acute static renewal conditions, we present evidence of physical size alteration of microplastics ingested by a planktonic crustacean. Ingested microplastics (31.5 µm) are fragmented into pieces less than 1 µm in diameter. Previous feeding studies have shown spherical microplastics either; pass unaffected through an organism and are excreted, or are sufficiently small for translocation to occur. We identify a new pathway; microplastics are fragmented into sizes small enough to cross physical barriers, or are egested as a mixture of triturated particles. These findings suggest that current laboratory-based feeding studies may be oversimplifying interactions between zooplankton and microplastics but also introduces a new role of Antarctic krill, and potentially other species, in the biogeochemical cycling and fate of plastic.

TL;DR: Bast fibres are defined as those obtained from the outer cell layers of the stems of various plants and find use in textile applications and are increasingly being considered as reinforcements for polymer-matrix composites as they are perceived to be sustainable as mentioned in this paper.
Abstract: Bast fibres are defined as those obtained from the outer cell layers of the stems of various plants. The fibres find use in textile applications and are increasingly being considered as reinforcements for polymer–matrix composites as they are perceived to be “sustainable”. The fibres are composed primarily of cellulose which potentially has a Young’s modulus of ∼140 GPa (being a value comparable with man-made aramid [Kevlar/Twaron] fibres). The plants which are currently attracting most interest are flax and hemp (in temperate climates) or jute and kenaf (in tropical climates). This review paper will consider the growth, harvesting and fibre separation techniques suitable to yield fibre of appropriate quality. The text will then address characterisation of the fibre as, unlike man-made fibres, the cross section is neither circular nor uniform along the length.

TL;DR: The qualitative and quantitative results prove that the proposed WOA-based trainer is able to outperform the current algorithms on the majority of datasets in terms of both local optima avoidance and convergence speed.
Abstract: The learning process of artificial neural networks is considered as one of the most difficult challenges in machine learning and has attracted many researchers recently. The main difficulty of training a neural network is the nonlinear nature and the unknown best set of main controlling parameters (weights and biases). The main disadvantages of the conventional training algorithms are local optima stagnation and slow convergence speed. This makes stochastic optimization algorithm reliable alternative to alleviate these drawbacks. This work proposes a new training algorithm based on the recently proposed whale optimization algorithm (WOA). It has been proved that this algorithm is able to solve a wide range of optimization problems and outperform the current algorithms. This motivated our attempts to benchmark its performance in training feedforward neural networks. For the first time in the literature, a set of 20 datasets with different levels of difficulty are chosen to test the proposed WOA-based trainer. The results are verified by comparisons with back-propagation algorithm and six evolutionary techniques. The qualitative and quantitative results prove that the proposed trainer is able to outperform the current algorithms on the majority of datasets in terms of both local optima avoidance and convergence speed.
