Autumn mass change and winter mass loss differ between migratory and nonmigratory butterflies

Poikilotherms have two major alternative strategies to deal with the inhospitable conditions of temperate winters: hibernation or migration. The vast majority of insects spend winter in a species-specific diapause resting stage, while others remain reproductively active after having migrated to more hospitable environments in the autumn. The butterfly clade Nymphalini offers an interesting possibi

Market shaping MNCs in emerging markets - stakeholder engagement and the role of embeddedness

This study delves into the phenomenon of collective market shaping in the context of multinational corporations (MNCs) in emerging markets. The study examines the firm's engagement activities and the importance of embeddedness in market shaping undeveloped in the literature. Theoretically this study builds on the literature on collective market shaping, stakeholder engagement and stakeholder embed

EndoC-βH5 cells are storable and ready-to-use human pancreatic beta cells with physiological insulin secretion

Objectives: Readily accessible human pancreatic beta cells that are functionally close to primary adult beta cells are a crucial model to better understand human beta cell physiology and develop new treatments for diabetes. We here report the characterization of EndoC-βH5 cells, the latest in the EndoC-βH cell family. Methods: EndoC-βH5 cells were generated by integrative gene transfer of immortal

A practical solution to the saturation problem in feedforward control for measurable disturbances

This paper treats the problem of control signal saturation caused by feedforward control from measurable load disturbances. An efficient feedforward compensator will often give significant peaks in the control signal at fast changes in the load disturbance. These peaks may cause the control signal to reach a saturation limit. In the paper, it is shown that the anti-windup function may cause unnece

Eye movements in visual impairment

This Special Issue describes the impact of visual impairment on visuomotor function. It includes contributions that examine gaze control in conditions associated with abnormal visual development such as amblyopia, dyslexia and neurofibromatosis as well as disorders associated with field loss later in life, such as macular degeneration and stroke. Specifically, the papers address both gaze holding

Anion-Specific Adsorption of Carboxymethyl Cellulose on Cellulose

Integration of fiber modification step with a modern pulp mill is a resource efficient way to produce functional fibers. Motivated by the need to integrate polymer adsorption with the current pulping system, anion-specific effects in carboxymethylcellulose (CMC) adsorption have been studied. The QCM-D adsorption experiments revealed that CMC adsorption to the cellulose model surface is prone to an

Binocular vision and foraging in ducks, geese and swans (Anatidae)

Wide variation in visual field configuration across avian species is hypothesized to be driven primarily by foraging ecology and predator detection. While some studies of selected taxa have identified relationships between foraging ecology and binocular field characteristics in particular species, few have accounted for the relevance of shared ancestry. We conducted a large-scale, comparative anal

A decision support system for watershed flood design purpose in China

The paper presents a computer-based decision support system for watershed planning andflood design purposes including a conceptual rainfall-runoff model. The software package uses up-to-date programing techniques in Windows environment which makes it flexible to handle, adaptableto new areas, and easy to test for different design criteria. The package is suitable for designproblems in small as wel

Resilience in Action: An Exploration of the Motivations of Wayúu Indigenous Women Human Rights Defenders in their Endeavor to Safeguard their Rights in La Guajira, Colombia.

Objectives: Colombia is proving to be a notable epicentre of risk for individuals actively engaged in human rights advocacy. Notwithstanding this pervasive risk, individuals continue to champion their cause on a daily basis. A trend is emerging of more and more Indigenous women taking prominent leadership roles to catalyse social change. With determination, these women are challenging entrenched s

Movie-ing Forward: Climate Change Narratives and Imaginaries in Children’s Animated Films

Children primarily learn about climate change (CC) through media, including children’s films. Films can influence emotions, shaping perceptions and actions regarding CC. However, research focusing on media narratives consumed by children is lacking, leaving a significant knowledge gap. To bridge this gap, this study employed narrative analysis, examining CC depictions in six children's animate

Robots2school: telepresence-mediated learning in the hybrid classroom – experiences in education support for children during cancer treatment: a qualitative study

Children with cancer experience recurring hospitalizations and isolation during treatment, which affect their school attendance. This study explores experiences of children with cancer, their classmates, and teachers with using the telepresence robot as a learning mediator in the hybrid classroom during treatment periods. 31 children with cancer (aged 7–17 years), 30 teachers, and 118 classmates p
