With the increasing need for effective elderly care solutions, this paper presents a novel federated learning-based system that uses smartphones as edge devices to monitor and enhance elderly care in real-time. In this system, elderly individuals carry smartphones equipped with Inertial Measurement Unit (IMU) sensors, including an accelerometer for activity recognition, a barometer for altitude detection, and a combination of the accelerometer, gyrometer, and magnetometer for location tracking. The smartphones continuously collect real-time data as the elderly individuals go about their daily routines. These data are processed locally on each device to train personalized models for activity recognition and contextual monitoring. The locally trained models are then sent to a federated server, where the FedAvg algorithm is used to aggregate model parameters, creating an improved global model. This aggregated model is subsequently distributed back to the smartphones, enhancing their activity recognition capabilities. In addition to model updates, information on the users’ location, altitude, and context is sent to the server to enable the continuous monitoring and tracking of the elderly. By integrating activity recognition with location and altitude data, the system provides a comprehensive framework for tracking and supporting the well-being of elderly individuals across diverse environments. This approach offers a scalable and efficient solution for elderly care, contributing to enhanced safety and overall quality of life. Full article

This article presents a theoretical framework for analysing the findings derived from the Diversity Barometer, a longitudinal study that collected data on immigration and diversity-related topics in Swedish society from 2005 to 2022. This article examines attitudes towards immigrants and migration in Sweden and how the historical context of Swedish race relations and structural racism shapes these attitudes. Specifically, the article focuses on attitudes regarding immigrants’ social rights and responsibilities, workplace diversity, cultural diversity, and spatial segregation. Our findings and analysis demonstrate how structural racism manifests itself through attitudes towards individuals with immigrant backgrounds in Sweden. Research has also revealed the pervasive nature of racial discrimination across various aspects of Swedish society, contributing to a divided society based on racial markers. However, the findings also show complexity in how Swedes’ attitudes toward immigrants are to be understood when they do not follow a simple horizontal division between Swedes and immigrants. Instead, it appears as an intricate vertical division where immigrants, their culture and their labour are accepted, albeit in a subordinate manner. Full article

Migration is topical in many counties, and attitudes towards immigration and ethnic diversity are volatile. In our longitudinal “Diversity Barometer”, we have studied changes in Swedes’ attitudes towards immigration and ethnic diversity in Sweden since 2005, using a postal questionnaire sent to a random sample of the Swedish population aged 18–75. In this article, we analyzed data from 2020 (n = 1035) in comparison with previous Diversity Barometer surveys from 2005 to 2018. The findings showed that Swedes had increased contact with immigrants from the Middle East, Asia and Africa. The majority had good experiences of studying or working with people with foreign background, although those with bad experiences had also increased. Attitudes towards immigration and ethnic diversity were more positive in 2020, thereby stopping a negative trend that started with the refugee influx in 2015. Positive attitudes were more established among women, younger people, those with higher education, people living in larger cities and those with more contact with people with foreign background. Sympathizers of political parties closer to the left wing were more positive towards immigration and ethnic diversity. We used political correctness, contact theory, strain theory and theory about group conflict/threats to provide hypothetical explanations for the observed changes in attitudes. Full article
