Exploitation and Remedial Duties

The concept of exploitation and potentially exploitative real-world practices are the subject of increasing philosophical attention. However, while philosophers have extensively debated what exploitation is and what makes it wrong, they have said surprisingly little about what might be required to remediate it. By asking how the consequences of exploitation should be addressed, this article seeks to contribute to filling this gap. We raise two questions. First, what are the victims of exploitation owed by way of remediation? Second, who ought to remediate? Our answers to these questions are connected by the idea that exploitation cannot be fully remediated by redistributing the exploiter's gain in order to repair or compensate the victim's loss. This is because exploitation causes not only distributive but also relational harm. Therefore, redistributive measures are necessary but not sufficient for adequate remediation. Moreover, this relational focus highlights the fact that exploitative real-world practices commonly involve agents other than the exploiter who stand to benefit from the exploitation. Insofar as these third parties are implicated in the distributive and relational harms caused by exploitation, there is, we argue, good reason to assign part of the burden of remediation to them

Evaluation of Refractory Metal Concentrations in Nano-Particulate Pressed-Powder Pellets Using LA-ICP-MS

Whole-rock geochemical analysis is a standard method to measure the chemical composition of ores. Analysis of refractory ore metals such as Ta and W typically requires fused bead and acid digestion followed by inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled mass spectrometry (ICP-MS). Since these techniques are time-consuming and expensive, there is a demand for methods that can quantitatively measure low elemental concentration of refractory ore metals using a less expensive and simple approach. This paper evaluates preparation and analytical procedures developed to obtain whole-rock element concentrations of ore samples and mineral concentrates. It shows that the production of nano-particulate pressed-powder pellets followed by LA-ICP-MS analysis of W and Ta ores can be used to determine, within the error margin, the concentrations of the refractory metals W, Ta, Nb, and Sn compared to a reference values obtained by solution analysis. The results have implications for developing a commercially viable method for analysis of refractory elements to benefit mineral processing given the simplicity and resource-efficiency of the combined pressed pellet production and laser ablation analytical methodology

CDIO faculty development course – Built-in implementation

To successfully implement the CDIO approach in engineering programs, a holistic approach is required, connecting the philosophy of the program with teaching and learning activities in the courses. One influential component in this interaction is faculty members and their competence in providing integrated learning experiences, in using active experiential learning methods, and in assessing student learning (CDIO Standard 10). As an effort to support such faculty development, a group of universities has been conducting activities directly aiming to enable and drive CDIO implementation in the participating universities (mainly within the EIT Raw Materials programme). In this paper, we will continue reporting and critically reflecting on these CDIO-based faculty development endeavours. Initially, a faculty development course was launched in 2016 at Chalmers University of Technology and offered to participants from other universities (Bhadani et al., 2017). The paper starts by outlining the adaptation of the course into its second version, followed by investigating the experiences from the first group in 2018. The course was designed to suit both experienced and novice faculty. It offered a staged introduction to CDIO implementation alternated with sessions in which participants worked on their own course development. The rationale for this design was to increase the direct usefulness for the participants, in that they should feel engaged and involved during learning and be able to immediately apply their learning to their own course. To estimate the impact of the course on participants’ actual course design and implementation, participants’ final presentations and feedback were analysed. Interviews were also conducted to gather information about the changes made in the participants’ own teaching, as well as the perceived influence of the CDIO course on those changes. The paper could be used to support organizers of faculty development courses in other universities, by documenting a model that can be implemented as a standard faculty training course

Video Development Methods for CDIO-Based Project Courses

Video utilization can be a powerful tool for teachers to stimulate students’ interest and support flexible and adaptive learning. Successful video-based learning implementation cannot be assured without careful consideration regarding desired quality, learning outcomes and video development methods. The investigation and sharing of experiences considering video development is indispensable and will contribute to spreading a culture of easily made, peer-reviewed videos, which will enhance teaching and learning. For CDIO-based courses, it is required that the video development methods are agile and cost-effective in production as to support continuous update of videos relevant for the course and other course activities. In this paper, we identify and describe video development methods from different CDIO-based project courses. The methods are classified based on the content type, the production style, the required resources and the video characteristics. All presented video development methods follow our general framework of video development process which has been previously published and consists of four interwoven steps - topic selection, learning objectives mapping, content generation and video recording. Based on semi-structured interviews with the course teachers, we present their experiences with those different development methods to create content specific videos pertaining to various Conceive-Design-Implement-Operate topics. As outcome, we suggest our preferable video development method depending on video content category. We conclude that the choice of video development method must consider the audience’s characteristics and needs while video content should be aligned with the course content, other learning activities and the literature. The video development methods suggested and described in this paper will assist educators to choose an appropriate video development method for their own courses and maximize the videos’ contribution to student learning

Cortical brain abnormalities in 4474 individuals with schizophrenia and 5098 control subjects via the enhancing neuro Imaging genetics through meta analysis (ENIGMA) Consortium

BACKGROUND: The profile of cortical neuroanatomical abnormalities in schizophrenia is not fully understood, despite hundreds of published structural brain imaging studies. This study presents the first meta-analysis of cortical thickness and surface area abnormalities in schizophrenia conducted by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta Analysis) Schizophrenia Working Group. METHODS: The study included data from 4474 individuals with schizophrenia (mean age, 32.3 years; range, 11-78 years; 66% male) and 5098 healthy volunteers (mean age, 32.8 years; range, 10-87 years; 53% male) assessed with standardized methods at 39 centers worldwide. RESULTS: Compared with healthy volunteers, individuals with schizophrenia have widespread thinner cortex (left/right hemisphere: Cohen's d = -0.530/-0.516) and smaller surface area (left/right hemisphere: Cohen's d = -0.251/-0.254), with the largest effect sizes for both in frontal and temporal lobe regions. Regional group differences in cortical thickness remained significant when statistically controlling for global cortical thickness, suggesting regional specificity. In contrast, effects for cortical surface area appear global. Case-control, negative, cortical thickness effect sizes were two to three times larger in individuals receiving antipsychotic medication relative to unmedicated individuals. Negative correlations between age and bilateral temporal pole thickness were stronger in individuals with schizophrenia than in healthy volunteers. Regional cortical thickness showed significant negative correlations with normalized medication dose, symptom severity, and duration of illness and positive correlations with age at onset. CONCLUSIONS: The findings indicate that the ENIGMA meta-analysis approach can achieve robust findings in clinical neuroscience studies; also, medication effects should be taken into account in future genetic association studies of cortical thickness in schizophrenia
