In recent decades, scholars have documented how globalisation and mobility have changed our relationship with linguistic, social and cultural norms. Yet in most educational contexts, evaluation systems still tend to support the teaching of homogeneous knowledge mastered by all, and to portray linguistic standards as key for social mobility. Drawing on qualitative interviews conducted with students on an international and multilingual higher education programme, this paper examines what the students claim they learn from a programme premised instead on the circulation of a multiplicity of norms, standards and practices. The interviews, conducted on the basis of a co-inquiry approach, suggest that the students learn to 1) deal productively and agentively with tensions, 2) rethink their positions and 3) open up to unexpected experiences when teachers support them in navigating multiple norms. In conclusion, the paper highlights how the research elucidates two kinds of norms at play in the programme, institutional and lived norms, and the relationship between them. It also reflects on the utility of discussing multilayered norms (Canagarajah 2006) openly in a globalised higher education context. [less ▲]

The Partnership for Chemicals Risk Assessment (PARC) is currently under development as a joint research and innovation programme to strengthen the scientific basis for chemical risk assessment in the EU. The plan is to bring chemical risk assessors and managers together with scientists to accelerate method development and the production of necessary data and knowledge, and to facilitate the transition to next-generation evidence-based risk assessment, a non-toxic environment and the European Green Deal. The NORMAN Network is an independent, well-established and competent network of more than 80 organisations in the field of emerging substances and has enormous potential to contribute to the implementation of the PARC partnership. NORMAN stands ready to provide expert advice to PARC, drawing on its long experience in the development, harmonisation and testing of advanced tools in relation to chemicals of emerging concern and in support of a European Early Warning System to unravel the risks of contaminants of emerging concern (CECs) and close the gap between research and innovation and regulatory processes. In this commentary we highlight the tools developed by NORMAN that we consider most relevant to supporting the PARC initiative: (i) joint data space and cutting-edge research tools for risk assessment of contaminants of emerging concern; (ii) collaborative European framework to improve data quality and comparability; (iii) advanced data analysis tools for a European early warning system and (iv) support to national and European chemical risk assessment thanks to harnessing, combining and sharing evidence and expertise on CECs. By combining the extensive knowledge and experience of the NORMAN network with the financial and policy-related strengths of the PARC initiative, a large step towards the goal of a non-toxic environment can be taken.

In addition, they declared that their “talk diet with friends”were associated with large gap between ideal and declared body shape.Conclusions:A social controlnorm was revealed involving a displacement of values affecting body weight and health in the latestage of adolescence to early adolescence, especially for boys.

The location choice of Stone Age settlements has been long considered to be influenced by environmental conditions. Proximity to water and sandy soils are most typical examples of those conditions. The notion of the influence resulted from the evidence from a relatively small amount of sites. During the recent decades the number of known settlements has increased to a level where statistical assessment of relation between environmental characteristics and settlement location choice is possible. To undertake this task we collected data about known Estonian Stone Age settlements and acquired environmental data of their locations using publicly available geological datasets. We provide univariate descriptive statistics of the distributions of variables describing site conditions and compare them to characteristics generally present in the environment. We experiment with a set of environmental variables including soil type, distance to water and a selection of geomorphometry derivatives of the digital elevation model. Quantitative assessment confirmed previous observations showing significant effect towards choice of sandy, dry location close to water bodies. The statistical analysis allowed us to assess the effect size of different characteristics. Proximity to water had the largest effect on settlement choice, while soil type was also of considerable importance. Abstract geomorphological variables Topographic Position Index and Topographic Wetness index also inform us about significant effects of surface forms. Differences of settlement locations during stages of the Stone Age are well observable. The environmental conditions of sites from the pre-pottery Mesolithic follow the general pattern but with the greatest variation. Narva and Comb Ware stage settlement locations preferences are nearly identical to each other showing preference of sandy higher areas near the shoreline and indicating increased site investment. For Corded Ware period a new settlement mode is observable which is not any more directly related to water bodies and can be explained by semi-agrarian subsistence and decreasing dependence on aquatic resources.

This paper proposes the augmentation of the adjacency model of networks for graph signal processing. It is assumed that no information about the network is available, apart from the initial adjacency matrix. In the proposed model, additional edges are created according to a Markov relation imposed between nodes. This information is incorporated into the extended-adjacency matrix as a function of the diffusion distance between nodes. The diffusion distance measures similarities between nodes at a certain diffusion scale or time, and is a metric adopted from diffusion maps. Similarly, the proposed extended-adjacency matrix depends on the diffusion scale, which enables the definition of a scale-dependent graph Fourier transform. We conduct theoretical analyses of both the extended adjacency and the corresponding graph Fourier transform and show that different diffusion scales lead to different graph-frequency perspectives. At different scales, the transform discriminates shifted ranges of signal variations across the graph, revealing more information on the graph signal when compared to traditional approaches. The scale-dependent graph Fourier transform is applied for anomaly detection and is shown to outperform the conventional graph Fourier transform. [less ▲]

Power allocation techniques, among which the max-min fairness power allocation (MMFPA) is one of the most widely used, are essential to guarantee good data throughput for all users in a cell. Recently, an efficient MMFPA algorithm for massive multiple-input multiple-output (MIMO) systems has been proposed. However, this algorithm is susceptible to the initial search interval employed by the underlying bisection search. Even if the optimal point belongs to the initial search interval, this algorithm may fail to converge to such a point. In this paper, we use the Perron-Frobenius theory to explain this issue and provide search intervals that guarantee convergence to the optimal point. Furthermore, we propose the bound test procedure as an efficient way of initializing the search interval. Simulation results corroborate our findings. [less ▲]
