Walking and cycling are considered sustainable transport modes, promoted as a means to reduce car traffic. In the scientific literature, they have mostly been investigated separately, but should be considered jointly to enable a modal shift. Both daytime and dark conditions need to be studied, to improve understanding of how environmental features are affected by temporal variation. A conceptual m

Based on recent advances in control theory, we propose the notion of jitter margin for periodic control tasks. The jitter margin isdefined as a function of the amount of constant delay in the controlloop, and it describes how much additional time-varying delay can betolerated before the loop goes unstable. Combined with schedulingtheory, the jitter margin can be used to guarantee the stability and

This chapter focuses on communication-centered change research and its implications for public sector organizations. It focuses on the organizational level and the communication processes through which changes are enacted. Special attention is given to coworkers and how they make sense in times of changes. Sensemaking processes play a crucial role in organizational changes; if managers and employe

This chapter explores how technological advances can shape our future consumption, marketing, and society. Using a McLuhanian theoretical lens, and the metaverse as an illustrative example of emerging technological development, the chapter unpacks the marketing and socio-political implications of technological advances. It delves into how brands have been using the current rendition of the metaver

The chapter identifies several themes that are potentially significant in future research on Gen Z and sustainable tourism consumption. The need for cross-generational and cross-cultural research is identified, especially in a longitudinal context. It is also noted that the majority of research is undertaken in the developed world and the authors highlight the need for research in less developed c

Small for gestational age (SGA) is considered an adverse birth outcome. Per- and polyfluoralkyl substances (PFAS) have become increasingly investigated as contributing environmental factors, thus far with inconclusive results. The current study aimed to investigate the hypothesized association between increased maternal PFAS levels in early pregnancy and an increased risk for SGA birth. This popul

We analyze the oxygen abundances of a stellar sample representative of the two major Galactic populations: the thin and thick disks. The aim is to investigate the differences between members of the Galactic disks and contribute to the understanding of the origin of oxygen chemical enrichment in the Galaxy. The analysis is based on the [O i] = 6300.30 Å oxygen line in high-resolution spectra (R ∼ 5

Objective: To determine the validity of 15 standardized instruments frequently used to measure the outcome of chronic arthritis treatment. Methods: Analyses were performed on data collected at a rehabilitation programme (n=216). The outcome measures evaluated were health-related quality of life, global health, pain, physical function and aerobic capacity. The instrument items were linked to the In

The linearly constrained minimum variance (LCMV) method is an extension of the classical minimum variance distortionless response (MVDR) filter, allowing for multiple linear constraints. Depending on the spatial filter length and the desired frequency grid, a direct computation of the resulting spatial beampattern may be prohibitive. In this paper, we exploit the rich structure of the LCMV express

We study the chemical abundances of the strontium filament found in the ejecta of eta Carinae. In particular, we derive the abundances of iron-peak elements from the spectra of their singly ionized ions present in the optical/infrared (IR) spectra. In this paper we analyse the spectrum of Mn II using a new non-local thermodynamic equilibrium (non-LTE) model for this system. In constructing this mo

Context Up-to-date information on infant survival after extremely preterm birth is needed for assessing perinatal care services, clinical guidelines, and parental counseling. Objective To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. Design, Setting, and Patients Population-based prospective observational study of extremely preterm infant

The existence of a vertical age gradient in the Milky Way disc has been indirectly known for long. Here, we measure it directly for the first time with seismic ages, using red giants observed by Kepler. We use Stromgren photometry to gauge the selection function of asteroseismic targets, and derive colour and magnitude limits where giants with measured oscillations are representative of the underl

The film of sIgA lining the intestinal epithelium plays a role in the regulation of the commensal microflora and prevention of pathogen invasion. We show that, in the absence of intentional immunization, all sIgA in the gut is produced by B-1a B cells. We also show that B-1a B cells and sIgA derive from lineage-negative precursors found in the fetal liver and located in the spleen after birth. The

In this paper we argue that Long Wave Theory provides a useful conceptual tool for understanding the transition from the industrial to the, post-industrial economy. While economic theories struggle to fully explain the structural changes involved in the shift towards the information economy, long wave theory offers a promising avenue for understanding the complex relationship between technology an
