Students’ attitudes to mathematics and performance in limits of functions

The main aim of this article is to discuss the attitudes to mathematics of students taking a basic mathematics course at a Swedish university, and to explore possible links between how well such students manage to solve tasks about limits of functions and their attitudes. Two groups, each of about a hundred students, were investigated using questionnaires, field notes and interviews. From the resu

Design strategies to reduce personal protective equipment noncompliance

Personal Protective Equipment (PPE) noncompliance has been addressed through various lenses. In current literature, there is a greater focus on improving training and safety culture. Improving PPE design to persuade PPE compliance is less explored, especially in sectors beyond healthcare. This study investigates the reasons behind PPE noncompliance across construction, maritime, and chimney sweepiPersonal Protective Equipment (PPE) noncompliance has been addressed through var-ious lenses.

Parental Perception of Infants’ use of Mobile Devices: A Qualitative Exploration

Despite the clear restrictive guidelines about the use of modern handheld devices among children younger than 2 years, parents are seen to extensively use these devices with their infants. However, parents’ perceptions in this regard remain unclear and underexplored especially, in the context of South Asian cultures such as Pakistan. This qualitative study aims to explore parents’ perceptions rega

Less frequent face looking in infancy is related to autism likelihood status but not diagnosis : A study of parent-infant interaction

Background: Previous research suggest that autistic children look less at faces than neurotypically developing children, but this finding is based predominantly on screen-based eye tracking studies, with unfamiliar faces used as stimuli. The aim of the current study was to assess 10-month-olds’ gaze to faces in a more naturalistic context - during free play with a parent - in relation to later aut

Historical Immigration Policies: Trends and Lessons

In recent years, scholars of migration have created several new immigration policy indexes, but most existing databases have limited temporal scope. They also focus, to a large extent, on the Global North. In this research note, we introduce the Historical Immigration Policy dataset (HIP), which begins to fill these gaps. We first provide an overview of the data and then describe how they offer ne

Cyclodextrins are oligosaccharides with a wide range of applications since the last decades of the 20th century, although their discovery occurred at the end of the 19th century. Due to their donut-like structure and, essentially, their amphiphilic characteristics, cyclodextrins make it possible to modify the physicochemical properties of many compounds through the formation of supramolecular comp

Sjuksköterskors erfarenheter av palliativ vård av barn med obotlig cancer - En litteraturstudie

Bakgrund: Sjuksköterskor har en central roll i den palliativa vården av barn med obotlig cancer vilket ställer krav på en god omvårdnad. Samtidigt känner sjuksköterskor sig oförberedda inför den komplexa uppgiften. Syfte: Belysa sjuksköterskors erfarenheter av palliativ vård av barn med obotlig cancer. Metod: En icke-systematisk litteraturstudie inkluderande tio kvalitativa studier som sammanställ

The Sounds of Silence: Making Sense of the Absence of Domestic Violence Victims Help Seeking During the COVID-19 Pandemic

Increased concern was raised globally at the outbreak of COVID-19 that victims of domestic violence would be even more at risk when isolated with a violent partner and out of reach of support due to restrictions. Swedish staff in violence against women services prepared for increased calls for help. Instead, a worrying silence arose in a time and place of high uncertainty. This paper analyses the

Migrants as sustainability actors : Contrasting nation, city and migrant discourses and actions

Although it is widely recognized that migration is socially transformative, the potential contributions of migrants to transformations towards sustainability in their destination areas are often overlooked in mainstream discourse on environmentalism and sustainability. Here we seek to identify current narratives of migrants and sustainability across individual, urban, and national scales. Migrants

Afterword : Towards a Tactical Turn?

In this afterword, Marie Cronqvist, Fredrik Mohammadi Norén, and Emil Stjernholm tie together the chapters in Media Tactics in the Long Twentieth Century and summarise some of the book's key themes. Three key knowledge contributions are highlighted. First, the volume foregrounds tactics as a study object in itself, not just the effects or outcomes of strategic thinking. Second, the book counters t

Window Tactics : Entangled Visual Propaganda in Neutral Sweden, 1939–1945

During the Second World War, neutral Sweden became a battleground for propaganda between warring nations, prominently displayed through window displays on Stockholm's streets. This chapter studies the overlooked realm of visual propaganda, particularly focusing on the strategic use of window displays by Germany, the US, the UK and the Soviet Union. By analysing archival material and newspaper sour

Numerical model development and analysis of a drop-on-demand inkjet application

The jet breakup and the potential occurrence of satellite droplets play a crucial role in the print quality of drop-on-demand (DOD) systems. This thesis focuses on developing a numerical model to simulate droplet formation utilizing the volume-of-fluid (VOF) method. A particular focus is on the occurrence of satellite droplets and how different fluid properties influence the jetting behaviour. The

Robotised Guard Tours in Security Systems

With the growing market for enhanced security combined with recent advancements in robotic technology, the possibility of integrating these two fields is of considerable interest. While traditional surveillance relies on mounted cameras and scheduled guard tours by humans, the next step would be to use a robot to complement a person in such systems. This project explores the integration of autonom

MULTISCALE COUPLINGS IN PROTOTYPE HYBRID DETERMINISTIC/STOCHASTIC SYSTEMS : PART II, STOCHASTIC CLOSURES

Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode

Development of students’ concept images in analysis.

Students’ pre-knowledge and conceptual development in analysis were investigated at a teacher education program to reveal what pre-knowledge endured and how the students perceived the concepts a year after the course had ended. Questionnaires and interviews were used to collect data. Two students’ results are presented in more detail in the article. The study was cognitively framed with the influe

Limits of functions - students solving tasks

This study was conducted to reveal how students at university level justify their solutions to tasks with various degrees of difficulty. The study is part of a larger study of students' concept formation of limits. The mathematical area is limits of functions. The study was carried out at a Swedish university at the first level of mathematics. The results are, however, applicable to other countrie

Sleep Duration, Cardiometabolic disease and Mortality: Proteomic links with incident diabetes

BackgroundNoncommunicable disease, in particular cardiovascular disease (CVD) and diabetes are a major cause of morbidity and mortality in the world. Short and long sleep durations are associated with adverse health outcomes, however, the biological mechanisms for these associations are not fully elucidated. The aim of this thesis is to investigate the association between sleep duration and proteo

Straightforward purification method for the determination of the activity of glucose oxidase and catalase in honey by extracting polyphenols with a film-shaped polymer

Glucose oxidase (GOX) and catalase (CAT) regulate the amount of H2O2 in honey, by generating or consuming it, so they are related to the antibacterial and antioxidant activity of honey. However, their activities are hardly analysed, since the process requires a previous dialysis that is non-selective, very time-consuming (>24 h), eco-unfriendly (>6L of buffer) and expensive. This research shows th
