Payment Systems as a Driver for Platform Growth in E-Commerce: Network Effects and Business Models

This chapter visits some of the fundamental concepts from platform economics, network effects, and network externalities. Further on, it discusses definitions of two-sided and multi-sided markets, how they are treated as business models. These concepts are further compared to the concept service ecosystem. A case of a payment service provider whose business model contributes to the growth of e-com

Detection of bacterial DNA in synovial fluid in dogs with arthritis : a comparison between bacterial culture and 16S rRNA polymerase chain reaction

Background: Septic arthritis (SA) is a serious condition in dogs that requires a prompt diagnosis and treatment to minimize long-term joint pathology. Although bacterial detection in synovial fluid (SF) through culture or cytology is often performed to confirm diagnosis, the sensitivity of these tests is low. The need for a reliable diagnostic tool to confirm the presence of bacteria in SF in huma

Insulin-like growth factor 1 gene transfer for sporadic Alzheimer's disease : New evidence for trophic factor mediated hippocampal neuronal and synaptic recovery-based behavior improvement

Sporadic Alzheimer's disease (sAD) is the most prevalent neurodegenerative disorder with no cure. Patients typically suffer from cognitive impairment imprinted by irreversible neocortex and hippocampal degeneration with overt synaptic and neuron dysfunction. Insulin-like growth factor 1 (IGF1) has proven to be a potent neuroprotective molecule in animal models of age-related neurodegeneration. In

Tourism and fishing

Recreational fishing is a major tourism activity and is integral to the “Blue economy”. Despite having high rates of participation and it being an important economic activity, especially in coastal, lacustrine and riverine areas, there is relatively little research on its various tourism dimensions, including its role in branding and marketing. This paper provides an introductory context for the f

Dual modality neutron and x-ray tomography for enhanced image analysis of the bone-metal interface

The bone tissue formed at the contact interface with metallic implants, particularly its 3D microstructure, plays a pivotal role for the structural integrity of implant fixation. X-ray tomography is the classical imaging technique used for accessing microstructural information from bone tissue. However, neutron tomography has shown promise for visualising the immediate bone-metal implant interface

Swedish rape offenders — a latent class analysis

Sweden has witnessed an increase in the rates of sexual crimes including rape. Knowledge of who the offenders of these crimes are is therefore of importance for prevention. We aimed to study characteristics of individuals convicted of rape, aggravated rape, attempted rape or attempted aggravated rape (abbreviated rape+), against a woman ≥18 years of age, in Sweden. By using information from the Sw

Methods and Strategies for Reducing Seclusion and Restraint in Child and Adolescent Psychiatric Inpatient Care

Restraints and seclusions are restrictive interventions used in psychiatric inpatient units when there is an imminent risk of harm to the patient or others. Coercive measures are controversial and can lead to negative consequences, including negative emotions, re-traumatization, injuries, or death. The article summarizes the last 10 years of literature regarding methods and strategies used for red

Urban crystallization and the morphogenesis of urban territories

We develop the perspective of crystallization as a way to shed a light on the morphogenesis and stabilization of urban territories. We start by describing crystallization as a consolidation of a visible and singular order that establishes certain privileged directions of growth and breaks spatial and temporal symmetries. We then illuminate how crystallization processes unfold at different scales,

Association of the Recurrent Rare Variant c.415T>C p.Phe139Leu in CLN5 with a Recessively Inherited Macular Dystrophy

Importance: Homozygous variants in the neuronal ceroid lipofuscinosis type 5 (CLN5) gene are associated with neuronal ceroid lipofuscinosis, a progressive neurologic disorder that leads to ataxia, seizures, and early death. The association between a homozygous variant in this gene and a macular dystrophy is described here. Objective: To describe an autosomal recessive macular dystrophy associated

Size for gestational age affects the risk for type 1 diabetes in children and adolescents : a Swedish national case–control study

Aim/hypothesis: Environmental factors are believed to contribute to the risk of developing type 1 diabetes. The aim of this study was to investigate how size for gestational age affects the risk of developing childhood type 1 diabetes. Methods: Using the Swedish paediatric diabetes quality register and the Swedish medical birth register, children with type 1 diabetes diagnosed between 2000 and 201

Experiences of becoming widowed in old age–a cross-countries study with qualitative interviews from Denmark and quantitative measures of association in a Swedish sample

Purpose: Becoming widowed is a stressful health-threatening event causing major life changes. We explored how widowed people experience becoming widowed and examined if these experiences are quantitatively associated with widowhood. Methods: A multi-methods study using an exploratory sequential mixed-methods approach including a qualitative descriptive study with widowed people from Denmark and a

Charge Interactions in a Highly Charge-Depleted Protein

Electrostatic forces are important for protein folding and are favored targets of protein engineering. However, interactions between charged residues are difficult to study because of the complex network of interactions found in most proteins. We have designed a purposely simple system to investigate this problem by systematically introducing individual and pairs of charged and titratable residues

RIFM fragrance ingredient safety assessment, p-tolualdehyde, CAS Registry Number 104-87-0

The existing information supports the use of this material as described in this safety assessment. p-Tolualdehyde was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity, skin sensitization potential, and environmental safety. Data from read-across analog benzaldehyde (CAS # 100-52-7) show that p-tolualdehyde is not

Kämpinge Interactive Reporting System

3D recording and visualization is standard practice at the Department of Archaeology and Ancient History at LU. This approach is currently used within several field projects to support documentation, data management and data analysis. The 3D data collected in the field are archived in the faculty server and are made available to researchers and students through the Lund University Digital Archaeol

Metagoverning social work knowledge structures.

The increasing fragmentation and the rising number of organizations in society create major challenges when implementing policy. In this article, we propose that the concept of metagovernance is useful when addressing these challenges in the governance of knowledge structures. The enhancement of knowledge structures in the Swedish social services is our study object. Networks at national, regional
