How Consumer Culture Grows : The Eigendynamik of Consumption
The current climate crisis has generated social pressure to slow consumption down. Despite this, consumer culture is continuously developing and growing. How is this possible? Our paper provides theoretical clues to this question by developing a novel model of thought for consumption growth, based on Georg Simmel’s notion of Eigendynamik.

Learning ecosystems in urban transformations : a research agenda
Current scholarship on urban transformation emphasizes the importance of learning, but the state of the art of research on learning dynamics in urban transformations is still conceptually and empirically fragmented. To address this deficit, we propose a research agenda and related conceptual apparatus that draws upon previous research in urban transformations and cognate fields. The proposed agend

A monitoring and evaluation system for complexity : a case study of the Brazilian national innovation policy
This chapter delves into the evaluation of national innovation policies through a case study of the Brazilian National Innovation Policy (NIP). Assessing these policies poses several challenges, including the difficulty of defining and measuring policy outcomes, the scarcity of reliable data, and the intricacies of interactions among various stakeholders involved in the policy. Additionally, polit
Lieb–Thirring inequalities for complex finite gap Jacobi matrices
We establish Lieb–Thirring power bounds on discrete eigenvalues of Jacobi operators for Schatten class complex perturbations of periodic and more generally finite gap almost periodic Jacobi matrices.
Asymptotics of Chebyshev polynomials, V. residual polynomials
We study residual polynomials, Rx0,n(e), e⊂ R, x∈ R\ e, which are the degree at most n polynomials with R(x) = 1 that minimize the sup norm on e. New are upper bounds on their norms (that are optimal in some cases) and Szegő–Widom asymptotics under fairly general circumstances. We also discuss several illuminating examples and some results in the complex case such as root asymptotics, a universal
Finite-Gap CMV Matrices : Periodic Coordinates and a Magic Formula
We prove a bijective unitary correspondence between (1) the isospectral torus of almost-periodic, absolutely continuous CMV matrices having fixed finite-gap spectrum E and (2) special periodic block-CMV matrices satisfying a Magic Formula. This latter class arises as E-dependent operator Möbius transforms of certain generating CMV matrices that are periodic up to a rotational phase; for this reaso
The Viral AlphaFold Database of monomers and homodimers reveals conserved protein folds in viruses of bacteria, archaea, and eukaryotes
Viruses are the most abundant and genetically diverse entities on Earth, yet the functions and evolution of most viral proteins remain poorly understood. Their rapid evolution often obscures evolutionary relationships, limiting the ability to assign functions using sequence-based methods. Although the conservation of protein fold can reveal deep homologies, viral proteins remain underrepresented i
The moment problem associated with the Stieltjes-Wigert polynomials
We consider the indeterminate Stieltjes moment problem associated with the Stieltjes-Wigert polynomials. After a presentation of the well-known solutions, we study a transformation T of the set of solutions. All the classical solutions turn out to be fixed under this transformation but this is not the case for the so-called canonical solutions. Based on generating functions for the Stieltjes-Wige
On the Krein and Friedrichs extensions of a positive Jacobi operator
We show that for a positive linear operator acting in ℓ2 and defined from anxn+1 + bn xn + an-1xn-1 its so-called Friedrichs and Krein extensions may be explicitly characterized by boundary conditions as n → ∞.
Perceptions and Implementation of Sustainability Practices in Small and Medium-Sized Enterprises in Nigeria's Retail Sector: A Qualitative Analysis
This study examines the perception, implementation, and challenges of sustainable supply chain practices among small and medium-sized enterprises (SMEs) in Nigeria's retail sector. The retail industry in emerging economies like Nigeria, is dominated by SMEs, are crucial for economic growth and employment but often face significant barriers to adopting sustainability. Using a qualitative metho
Accuracy of EEG Slow Wave Activity in Predicting Favorable Outcome in Patients With Hypoxic Brain Injury—A Protocol for a Substudy of the STEPCARE Trial
Background: Early restitution of electroencephalogram (EEG) slow wave activity (SWA) may be able to predict favorable functional outcome after cardiac arrest. SWA can be monitored using the C-Trend Index, a recently developed dynamic numerical index computed using commercially available medical device software. Methods: This is a pre-planned prospective substudy of the randomized controlled Sedati
Mobilising safety? Public order and the coordination of security guards in public transport in Stockholm
This study contributes to the growing literature on mobile work by examining the coordination of safety practices in public transport in Stockholm. We explore how safety, a critical and evolving theme in mobility studies, intersects with mobile work and its associated coordination challenges. Since the introduction of safety policies, security guards have focused on ‘circulatory maintenance’, a pr
Strategies for present and future bubbler irrigation system management in a Saharan date palm oasis under climate change
Date palm oases in North Africa have historically supported agriculture through indigenous irrigation techniques such as foggaras and tabias, made possible by a relatively stable water supply. However, the sustainability of these systems is increasingly threatened by irrational water use, climate change and environmental resources degradation. In response to these challenges, we introduced and eva
An updated kinetic mechanism for aluminum gas-phase combustion in oxygen and steam environments
Aluminum (Al), as a carbon-free energy source, features favorable characteristics regarding its production, transportation, utilization, and recyclability. The combustion of single Al particles mainly occurs as a vapor-phase diffusion flame, wherein the gas-phase combustion kinetics plays an important role. However, the understanding of the kinetics is still limited and rate constants for the same
