During planar motion, contact surfaces exhibit a coupling between tangential and rotational friction forces. This article proposes planar friction models grounded in the LuGre model and limit surface theory. First, distributed planar extended state models are proposed, and the elastoplastic model is extended for multidimensional friction. Subsequently, we derive a reduced planar friction model cou
Using social network theory, we measure the reputation of boards and directors based on the centrality of their respective networks. Directors commit greater effort, as measured by actual director attendance rates, to directorships they consider more prestigious. Results are robust to controlling for standard proxies of reputation as well as using alternative measures of centrality to identify pre
Viruses compete with each other for limited cellular resources, and some deliver defense mechanisms that protect the host from competing genetic parasites 1. PARIS is a defense system, often encoded in viral genomes, that is composed of a 55 kDa ABC ATPase (AriA) and a 35 kDa TOPRIM nuclease (AriB) 2. However, the mechanism by which AriA and AriB function in phage defense is unknown. Here we show
The nitrogen (N) cycle is a familiar concept. As is the much simplified, often diagrammatic, representation commonly used to illustrate the scale, importance and interconnectedness of this global cycle that links air, water, rocks and living beings. However, in this representation, humans are often presented as a seemingly minor entity or not explicitly shown at all. This can obscure the idea that
BACKGROUND: The Surprise Question (SQ) is a common method aimed at identifying frail patients who need serious illness conversations to integrate a palliative approach. However, little is known about whether the SQ identifies patients on hemodialysis who perceive that they are declining or have low health-related quality of life (HRQoL)-important aspects when considering the need for serious illne
The concept boat All Aboard was designed to meet women's expectations of leisure boats. A constellation of firms worked together to find solutions that could lead to business opportunities by challenging the implicit male norms of the leisure boat industry. This article examines the cultural notions of gender and equality that mattered in the process and explores the relationship between bodies, t
What does it mean to love one's job? This article argues that for an understanding of power and agency in the labour market, particularly in the service and retail industry, passion needs to be given more consideration. Building on ethnographic observations and interviews with sales assistants and store managers within fashion retailing, the reasons for employees to perform 'aesthetic labour' are
This introduction presents an overview of the key concepts covered in the subsequent chapters of this book. The book examines how digital technologies interact with consumer society in a broad range of processes that can be termed the digitalization of consumption. It addresses the larger implications of digitalization processes for society and markets, including the social sciences, companies, co
This special issue of the Journal of Cultural Economy focuses on the digitalization of consumption and its social, cultural, ethical, political, and gendered implications. It thus answers the call for more research on how digital devices spread from the purely personal domain to multiple sociocultural domains. Through their use, new cultural practices have emerged between consumers and these devic

The present research work investigates the barriers of weak IoT adoption in agrifood transportation, with special reference to India. It is built on a premise that few barriers upshots from the other more impactful ones. Thus, it is important to identify their linkages and classify them based on their strength of relationship. The data collected from 13 agricultural technology (AgriTech) firms of
This chapter looks at the way collective practices of comics creation and publicationcan form feminist attachments, with a focus on the comics anthologyDrawing the Line, Indian Women Fight Back! (Kuriyan, Bertonasco, Bartscht, &Burton 2015). Drawing the Line consists of fourteen short comics drawn by agroup of professional and amateur Indian women who reflect upon their experiencesof gendered

When lab resources are shared among multiple research projects, issues such as experimental integrity, replicability, and data safety become important. Different research projects often need different software and settings that may well conflict with one another, and data collected for one project may not be safeguarded from exposure to researchers from other projects. In this paper we provide an
Fertility requires the faithful proliferation of germ cells and their differentiation into gametes. Controlling these cellular states demands precise timing and expression of gene networks. Nucleic acid binding proteins (NBPs) play critical roles in gene expression networks that influence germ cell development. There has, however, been no functional analysis of the entire NBP repertoire in control
Achievement of sustainability goals is an epic task for developing economies that still strive to fulfil their basic needs. The availability of limited resources in the developing world vis-à-vis the ever-increasing demand poses further challenges to developing economies willing to transition into circular economies. Reverse logistics (RL) can facilitate this transition towards a circular economy
BACKGROUND: Compared to ischemic stroke, sex differences in patient outcomes following intracerebral hemorrhage (ICH) are underreported. We aimed to determine sex differences in mortality and functional outcomes in a large, unselected Swedish cohort.METHODS: In this observational study, data on 22,789 patients with spontaneous ICH registered in the Swedish Stroke Register between 2012 and 2019 wer
AIM: To describe sociodemographic disparities in temporal trends of incidence and age distributions of first registered osteoarthritis (OA) diagnosis in southern Sweden.METHODS: We identified all Skåne residents aged 35+ who had lived in the region at any point during the period 2006-2019 with no previous OA diagnosis (ICD-10 codes M15-M19) for 8 years prior to inclusion in the study (n = 849,061)
