A two-experiment study assessed throwing performance in VR and real life. The first experiment was a direct comparison of a carnival type throwing game in which participants attempted to throw 20 ...balls into a bucket from distances of 5 and 10 ft. Fifteen participants completed the task in both real life and in an identical VR environment. In the second experiment, the same task was repeated at the 5ft distance only with the addition of a randomized order of three different VR controllers and the real-life condition. Results from both experiments indicate substantial differences between real life and VR performance along with differences between controllers. Significant VR research has stressed enhancing visual quality to better replicate real life. However, the focus needs to shift to examine creating accurate psychomotor interactions to achieve more accurate performance and ultimately training success.
The EU's fishing fleet engages in extensive fishing activities in the Exclusive Economic Zones of non‐EU countries as well as in areas beyond national jurisdiction. These activities are regulated by ...an external dimension in the EU's Common Fisheries Policy (CFP). We review the relationship between the CFP, including regulations for the Sustainable Management of External Fishing Fleets (SMEFF) and the role of Sustainable Fisheries Partnership Agreements (SFPAs) and Regional Fisheries Management Organisations (RFMOs), and the internationally agreed aims and definitions of sustainability provided by the United Nations Sustainable Development Goals (SDGs). The SDG that most directly relates to fish and fisheries is goal 14, to "conserve and sustainably use the oceans." This paper, however, focuses on relationships between the CFP and SDGs that target social and economic dimensions, including those aiming to eliminate poverty (1) and hunger (2), improve health (3), provide decent work and economic growth (8), and achieve gender equality (5) and peaceful institutions (16). We identify several areas where the EU's external fishing fleet interacts with different facets of those goals, and suggest some important improvements that can be made to support the development of the EU’s external fleet into a contributor, rather than counterforce, to sustainable development in line with commitments under Agenda 2030. We provide a first and broad overview of an important area for future interdisciplinary research. We conclude by identifying specific questions that can provide starting points for further in‐depth analyses of the sustainability of EU fishing activities in external waters.
Neste trabalho será apresentada a experiência vivenciada por bolsistas do Programa Institucional de Bolsas de Iniciação à Docência (PIBID) do IFRJ, na aplicação da atividade “Medindo com o Auxilio do ...Teodolito”. Ela consistiu de uma prática em que os alunos puderam medir a altura do prédio da escola, utilizando um teodolito confeccionado com materiais de baixo custo. O experimento carrega o objetivo de mostrar aos estudantes uma aplicação da Trigonometria no cotidiano, utilizando a relação trigonométrica tangente para medir uma distância inacessível com instrumentos de medida convencionais, levando aos alunos a uma aula mais dinâmica. Durante esta experiência foram aplicados dois testes que puderam verificar quantitativamente a contribuição da atividade, que foi considerada satisfatória ao final do experimento, pois atingiu o seu objetivo de contribuir de forma significante para o aprendizado dos alunos sobre as relações trigonométricas, em especial a tangente. Além de ter possibilitado a detecção de algumas outras dificuldades em matemática apresentadas pelos alunos.
