Immense beyond imagination, the untamed rainforests of western New Guinea represent a biodiversity hotspot, home to several unique species of flora and fauna. The territory’s astonishing beauty and diversity is underpinned by a stunning array of natural resources. The island is also home to many indigenous communities practicing hundreds of local languages and traditions and depending on their natural environment for maintaining their traditional livelihoods, identity and culture. The territory’s much-contested decolonization process in the 1950-60s led to widespread discontent among indigenous Papuans and gave rise to persistent dissent from Indonesian rule, routinely met with disproportionately violent action by Indonesian security forces. Adding to these longstanding colonial ills and grievances, indigenous Papuan communities also struggle to grapple with inequitable allocation of land and resources, extreme pollution and environmental degradation caused by the mining and palm oil sectors. In the meantime, climate-exacerbated weather events have become more frequent in the region creating new tensions by putting an additional strain on natural resources and thus leading to an increased level of insecurity and inequality. In particular, these challenges have a disproportionate and profound impact on indigenous Papuan women, whose native lands are deeply embedded in their cultural and ethnic identity, and who are dependent on access to land to carry out their prescribed roles. Displacement also puts women at further risk of violence. Adding to sexual violence and displacement experienced by indigenous Papuan women, the loss of traditional lands and resources has been identified as having a singularly negative impact on women as it impedes their empowerment and makes them vulnerable to continued violence. The Papuan experience thus serves as a timely illustration to exemplify how environmental factors, such as resource extraction and climate change, not only amplify vulnerabilities and exacerbate pre-existing inequalities stemming from colonial times, they also give rise to gendered consequences flowing from large-scale degradation and loss of the natural environment.

Indigenous Papuans on the western half of the island of New Guinea, have experienced intersecting environmental, social, and political crises, within the context of a movement seeking self-determination. These ongoing crises are exacerbated by longstanding grievances over the Grasberg mine (which contains significant reserves of copper and gold), and environmental degradation caused by the mining and palm oil sectors, as well as the legacy of colonialism on the allocation of land and resources.

From the article: Abstract Adjustment and testing of a combination of stochastic and nonstochastic observations is applied to the deformation analysis of a time series of 3D coordinates. Nonstochastic observations are constant values that are treated as if they were observations. They are used to formulate constraints on the unknown parameters of the adjustment problem. Thus they describe deformation patterns. If deformation is absent, the epochs of the time series are supposed to be related via affine, similarity or congruence transformations. S-basis invariant testing of deformation patterns is treated. The model is experimentally validated by showing the procedure for a point set of 3D coordinates, determined from total station measurements during five epochs. The modelling of two patterns, the movement of just one point in several epochs, and of several points, is shown. Full, rank deficient covariance matrices of the 3D coordinates, resulting from free network adjustments of the total station measurements of each epoch, are used in the analysis.

Laboratory study using a repeated measures design. The aim of this study was to determine if ankle proprioception is targeted in exercises on unstable surfaces. Lateral ankle sprain (LAS) has recurrence rates over 70%, which are believed to be due to a reduced accuracy of proprioceptive signals from the ankle. Proprioceptive exercises in rehabilitation of LAS mostly consist of balancing activities on an unstable surface. The methods include 100 healthy adults stood barefoot on a solid surface and a foam pad over a force plate, with occluded vision. Mechanical vibration was used to stimulate proprioceptive output of muscle spindles of triceps surae and lumbar paraspinal musculature. Each trial lasted for 60 s; vibration was applied from the 15th till the 30th second. Changes in mean velocity and mean position of the center of pressure (CoP) as a result of muscle vibration were calculated. Results show that on foam, the effect of triceps surae vibration on mean CoP velocity was significantly smaller than on a solid surface, while for paraspinal musculature vibration the effect was bigger on foam than on solid surface. Similar effects were seen for mean CoP displacement as outcome. Exercises on unstable surfaces appear not to target peripheral ankle proprioception. Exercises on an unstable surface may challenge the capacity of the central nervous system to shift the weighting of sources of proprioceptive signals on balance.

The purpose of this paper is to reflect on the experiences of safety and security management students, enrolled in an undergraduate course in the Netherlands, and present quantitative data from an online survey that aimed to explore the factors that have contributed to students’ satisfaction with, and engagement in, online classes during the COVID-19 pandemic. The main findings suggest an interesting paradox of technology, which is worth further exploration in future research. Firstly, students with self perceived higher technological skill levels tend to reject online education more often as they see substantial shortcomings of classes in the way they are administered as compared to the vast available opportunities for real innovation. Secondly, as opposed to democratising education and allowing for custom-made, individualistic education schedules that help less-privileged students, online education can also lead to the displacement of education by income-generating activities altogether. Lastly, as much as technology allowed universities during the COVID-19 pandemic to continue with education, the transition to the environment, which is defined by highly interactive and engaging potential, may in fact be a net contributor to the feelings of social isolation, digital educational inequality and tension around commercialisation in higher education.

Indigenous rights’ relationship to ecological justice in Amazonia has not been explicitly explored in the literature. As social scientists rarely talk about violence against non-humans, this case study of conservation in Amazonia will explore this new area of concern. Ethical inquiries in conservation also engage with the manifold ways through which human and nonhuman lives are entangled and emplaced within wider ecological relationships, converging in the notion of environmental justice, which often fails to account for overt violence or exploitation of non-humans. Reflecting on this omission, this chapter discusses the applicability of engaged social science and conservation to habitat destruction in Amazonia, and broader contexts involving violence against non-humans. The questions addressed in this chapter are: is the idea of ecological justice sufficiently supported in conservation debate, and more practical Amazonian contexts? Can advocacy of inherent rights be applied to the case of non-humans? Can indigenous communities still be considered 'traditional' considering population growth and increased consumptive practices? Concluding that the existing forms of justice are inadequate in dealing with the massive scale of non-human abuse, this chapter provides directions for conservation that engage with deep ecology and ecological justice in the Amazonian context. doi: 10.1007/978-3-030-29153-2 LinkedIn: https://www.linkedin.com/in/helenkopnina/

Environmental unsustainability is due to both structural features and historically specific characteristics of industrial capitalism resulting in specific patterns of production and consumption, as well as population growth. Sustainability literature criticises the established corporate and political power hegemonies, interested in maintaining economic growth, as well as inability or unwillingness of citizen-consumers to counteract these hegemonic tendencies. Yet, official policies are still targeted at social and economic ‘development’ as a panacea for unsustainability challenges. Instead, renewed accent on social and economic objectives are outlined by a set of sustainable development goals (SDG) that include objectives of fighting poverty, promoting better health, reducing mortality, and stimulating equitable economic growth. What is less commonly critiqued is the underlying morality of unsustainability and ethical questions concerned with the ‘victims of unsustainability’ outside of socioeconomic discourse. The achievement of SDG goals, as will be further elaborated on in this article, is unlikely to lead to greater social equality and economic prosperity, but to a greater spread of unsustainable production and consumption, continuous economic as well as population growth that has caused environmental problems in the first place and further objectification of environment and its elements. This article argues that an invocation of ethical duty toward environment and its elements is required in order to move beyond the current status quo. Such ethical approach to unsustainability can effectively address the shortcomings of the mainstream sustainability discourse that is mainly anthropocentric and therefore fails to identify the correct locus of unsustainability.

In wheelchair sports, the use of Inertial Measurement Units (IMUs) has proven to be one of the most accessible ways for ambulatory measurement of wheelchair kinematics. A three-IMU configuration, with one IMU attached to the wheelchair frame and two IMUs on each wheel axle, has previously shown accurate results and is considered optimal for accuracy. Configurations with fewer sensors reduce costs and could enhance usability, but may be less accurate. The aim of this study was to quantify the decline in accuracy for measuring wheelchair kinematics with a stepwise sensor reduction. Ten differently skilled participants performed a series of wheelchair sport specific tests while their performance was simultaneously measured with IMUs and an optical motion capture system which served as reference. Subsequently, both a one-IMU and a two-IMU configuration were validated and the accuracy of the two approaches was compared for linear and angular wheelchair velocity. Results revealed that the one-IMU approach show a mean absolute error (MAE) of 0.10 m/s for absolute linear velocity and a MAE of 8.1◦/s for wheelchair angular velocity when compared with the reference system. The twoIMU approach showed similar differences for absolute linear wheelchair velocity (MAE 0.10 m/s), and smaller differences for angular velocity (MAE 3.0◦/s). Overall, a lower number of IMUs used in the configuration resulted in a lower accuracy of wheelchair kinematics. Based on the results of this study, choices regarding the number of IMUs can be made depending on the aim, required accuracy and resources available.
