Negative chain referral sampling : doing justice to subcultural diversity

This paper calls for renewed consideration of the way researchsubjects are selected in the study of subcultures. All too often,subcultural researchers limit themselves to the use of one or twoof the orthodox sampling designs, such as ‘conveniencesampling’ (selecting subjects who are readily available) or ‘chainreferral sampling’ (selecting a readily available subject who refersthe researcher to ot

Equal prevalence of severe cervical dysplasia by HPV self-sampling and by midwife-collected samples for primary HPV screening : A randomised controlled trial

Objectives HPV self-sampling is an option for cervical screening. The aim of this randomised study was to investigate the compliance, prevalence of HPV, and prevalence of severe dysplasia in a vaginal self-sampling group in comparison to cervical samples collected by midwives (control arm). The hypothesis was that there would be no difference between vaginal self-sampling and cervical sampling to

The Changing Role of Nordic Courts

The Supreme Courts in all the Nordic countries reserve, and exercise, the power to set aside unconstitutional laws. In this way, they protect the rule of law and the human rights that are enshrined in their national constitutions. However, they go about this in different ways and treat different constitutional rights in ways distinct from one another. In this chapter, I discuss the development of

Extraction of sugarcane bagasse arabinoxylan, integrated with enzymatic production of xylo-oligosaccharides and separation of cellulose

Sugarcane processing roughly generates 54 million tonnes sugarcane bagasse (SCB)/year, making SCB an important material for upgrading to value-added molecules. In this study, an integrated scheme was developed for separating xylan, lignin and cellulose, followed by production of xylo-oligosaccharides (XOS) from SCB. Xylan extraction conditions were screened in: (1) single extractions in NaOH (0.25

Exploring Codon Adjustment Strategies towards Escherichia coli-Based Production of Viral Proteins Encoded by HTH1, a Novel Prophage of the Marine Bacterium Hypnocyclicus thermotrophus

Marine viral sequence space is immense and presents a promising resource for the discovery of new enzymes interesting for research and biotechnology. However, bottlenecks in the functional annotation of viral genes and soluble heterologous production of proteins hinder access to downstream characterization, subsequently impeding the discovery process. While commonly utilized for the heterologous e

Neutrophil extracellular traps in colorectal cancer progression and metastasis

Neutrophils form sticky web-like structures known as neutrophil extracellular traps (NETs) as part of innate immune response. NETs are decondensed extracellular chromatin filaments comprising nuclear and cytoplasmic proteins. NETs have been implicated in many gastrointestinal diseases including colorectal cancer (CRC). However, the regulatory mechanisms of NET formation and potential pharmacologic

Prediction of improvement after anterior cruciate ligament reconstruction

The retrospective investigation was carried out to assess whether subjects who fulfilled our proposed recruitment criteria responded more favorably to anterior cruciate ligament reconstruction (ACLR) than those who did not. We retrospectively analyzed 109 skeletally mature subjects (78 men and 31 women) according to the following proposed criteria of recruitment: (1) pre-injury Tegner activity sco

Burning material behaviour in hypoxic environments : An experimental study examining a representative storage arrangement of acrylonitrile butadiene styrene, polyethylene bubble wrap, and cardboard layers as a composite system

Cone calorimeter and controlled atmosphere cone calorimeter experiments were conducted on various samples. The intent of the tests was to examine the behavior of uniform and composite samples in a range of thicknesses, irradiances, and oxygen concentrations. Single, uniform layers of acrylonitrile butadiene styrene (ABS) were compared to a composite mix, comprising of ABS with a surface layer of c

Modeling and forecasting of metrological factors using arch process under different errors distribution specification

Various weather phenomenon are difficult to model and forecast with high precision. This study has modelled and forecasted the various parameter namely maximum and minimum temperature, morning and evening relative humidity using parametric models namely Autoregressive Integrated Moving Average (ARIMA) and Generalized Autoregressive conditional heteroskedasticity (GARCH)) models. The data consisted

Monitoring bee health in European agroecosystems using wing morphology and fat bodies

Current global change substantially threatens pollinators, which directly impacts the pollination services underpinning the stability, structure and functioning of ecosystems. Amongst these threats, many synergistic drivers, such as habitat destruction and fragmentation, increasing use of agrochemicals, decreasing resource diversity, as well as climate change, are known to affect wild and managed

Calmodulin complexes with brain and muscle creatine kinase peptides

Calmodulin (CaM) is a ubiquitous Ca2+ sensing protein that binds to and modulates numerous target proteins and enzymes during cellular signaling processes. A large number of CaM-target complexes have been identified and structurally characterized, revealing a wide diversity of CaM-binding modes. A newly identified target is creatine kinase (CK), a central enzyme in cellular energy homeostasis. Thi

Molecular determinants of disease severity in urinary tract infection

The most common and lethal bacterial pathogens have co-evolved with the host. Pathogens are the aggressors, and the host immune system is responsible for the defence. However, immune responses can also become destructive, and excessive innate immune activation is a major cause of infection-associated morbidity, exemplified by symptomatic urinary tract infections (UTIs), which are caused, in part,

Calcein Fluorescence Quenching to Measure Plasma Membrane Water Flux in Live Mammalian Cells

Aquaporins (AQPs) are membrane channel proteins that facilitate the movement of water down osmotic gradients across biological membranes. This protocol allows measurements of AQP-mediated water transport across the plasma membrane of live mammalian cells. Calcein is a fluorescent dye that is quenched in a concentration-dependent manner. Therefore, on short timescales, its concentration-dependent f

Patterns of resource integration in the self-service approach to business analytics

The main premise of Self-Service Business Analytics (SSBA) is to make business employees autonomous during the data analytical process. To empower business employees, organizations are decentralizing their analytical capabilities through an SSBA approach. Yet, little is known about how employees integrate resources, such as, among others, personal competencies, environment resources including tech

Data philanthropy : An explorative study

Data philanthropy, which is firm donations of data, data scientists, and data technologies for social good, is a powerful new phenomenon that offers benefits to both donor firms and society. In this explorative research we unpack data philanthropy, providing definitions, and examples along with a theoretical perspective from corporate philanthropy and strategic management. We view data through a l

The assumptions and profiles behind IT security behavior

Among the major IT security challenges facing organizations is non-malicious employee behavior that nevertheless poses significant threats to an organization's IT security. Using a grounded theory methodology, this paper finds that organizational security behaviors are inherently related to employee assumptions regarding the importance of IT security policy compliance and regarding the reason why
