Multiple-stressor effects of dicyandiamide (DCD) and agricultural stressors on trait-based responses of stream benthic algal communities

Agricultural practices often result in multiple stressors affecting stream ecosystems, and interacting stressors complicate environmental assessment and management of impacted streams. The nitrification inhibitor dicyandiamide (DCD) is used for nitrogen management on farmland. Effects of leached DCD on stream ecosystems are still largely unstudied, even though it could be relevant as a stressor on

Biotic interactions modify multiple-stressor effects on juvenile brown trout in an experimental stream food web

Agricultural land use results in multiple stressors affecting stream ecosystems. Flow reduction due to water abstraction, elevated levels of nutrients and chemical contaminants are common agricultural stressors worldwide. Concurrently, stream ecosystems are also increasingly affected by climate change. Interactions among multiple co-occurring stressors result in biological responses that cannot be

High-throughput amplicon sequencing and stream benthic bacteria : Identifying the best taxonomic level for multiple-stressor research

Disentangling the individual and interactive effects of multiple stressors on microbial communities is a key challenge to our understanding and management of ecosystems. Advances in molecular techniques allow studying microbial communities in situ and with high taxonomic resolution. However, the taxonomic level which provides the best trade-off between our ability to detect multiple-stressor effec

Multiple-stressor effects on stream invertebrates : DNA barcoding reveals contrasting responses of cryptic mayfly species

Most freshwater ecosystems are subject to multiple anthropogenic stressors, which commonly reduce biodiversity across all levels. Existing freshwater bioassessment programmes aim at identifying responses of aquatic biota to stressors. For practical reasons, higher-level taxonomic groups (e.g. genus or family) are often used in these programmes. This approach, however, may bias assessment results a

Interactive multiple-stressor effects of the antibiotic monensin, cattle effluent and light on stream periphyton

Streams draining agricultural land are simultaneously exposed to multiple stressors including agricultural antibiotics and effluent from surface water run-off. The potential interactive effects of these contaminants on stream benthic communities are poorly understood. Using a streamside channel experiment with a full factorial, repeated-measures design, we assessed the individual and combined effe

Validation of the movement disorder society criteria for the diagnosis of 4-repeat tauopathies

Background: The Movement Disorder Society criteria for progressive supranuclear palsy introduced the category “probable 4-repeat (4R)-tauopathy” for joint clinical diagnosis of progressive supranuclear palsy and corticobasal degeneration. Objectives: To validate the accuracy of these clinical criteria for “probable 4R-tauopathy” to predict underlying 4R-tauopathy pathology. Methods: Diagnostic acc

Modeling National Interdependent Critical Infrastructures : Application and Discussion for the Swedish Power and Internet Backbone

Critical Infrastructures (CIs) have a vital role in the functioning and development of our modern societies. To accurately understand the potential consequences of critical infrastructure disruptions, dependencies and potential cascading effects between CIs have to be considered in risk governance. As a step towards creating a system-of-systems model of Sweden’s national technical CIs, this paper

The intrinsically disordered RNR inhibitor Sml1 is a dynamic dimer

Sml1 is a small ribonucleotide reductase (RNR) regulatory protein in Saccharomyces cerevisiae that binds to and inhibits RNR activation. NMR studies of 15N-labeled Sml1 (104 residues), as well as of a truncated variant (residues 50−104), have allowed characterization of their molecular properties. Sml1 belongs to the class of intrinsically disordered proteins with a high degree of dynamics and ver

CCL2 secreted from cancer-associated mesothelial cells promotes peritoneal metastasis of ovarian cancer cells through the P38-MAPK pathway

Epithelial ovarian cancer (EOC) is considered to secrete various factors in order to promote peritoneal dissemination through cell-to-cell interaction between cancer and mesothelial cells. We previously revealed that TGF-β secreted from EOC induces normal human peritoneal mesothelial cells (HPMCs) to differentiate into cancer-associated mesothelial cells (CAMCs). However, the relationship between

The contribution of localization management system on zakat institution performance

This paper attempts to analyze the concept of localization and its relationship with the psychological performance of zakat. It argued that localization could produce development opportunities from the management decentralization of supply chain in zakat institution. In this study, localization is treated as the mediator, while property rights of zakat and asset specificity performed as the indepe

Restructuring foreign worker policy and community transformation in Malaysia

Malaysia is one of the most rapidly growing economies in Asia and is blessed with foreign workers inflow to sustain the economic growth process. However, the strong national sentiments among the local community, which harbors ill perception towards the foreign workers, lead to regrettably vague policies concerning foreign workers. As far as this issue is concerned, Malaysia needs to reform the pol

Taking the Ache out of Shakespeare : The Experience of Teaching Shakespeare's Plays Through Performance

This paper discusses the experience of teaching William Shakespeare’s plays through performance and staging the plays with university students as part of the learning experience. The learning outcomes are treated in three sections – the first relating the effects of performance on the students’ linguistic proficiency, the second giving a few examples of how the students discover and learn to maste

Terra firma-forme dermatosis : Differential diagnosis and response to salicylic acid therapy

Terra firma-forme dermatosis (TFFD), first described by Duncan in 1987, is a relatively common but probably underdiagnosed condition, characterized by a reticular hyperpigmented dirtlike eruption resistant to washing with common soap but typically removed with rubbing with 70% isopropyl alcohol. We present a case of TFFD in an 8-year-old boy with rapid response to 5% salicylic acid in petrolatum o

Socioecological and biological associations of lower levels of physical activity in 8-year-old children : A 2-year prospective study

Objectives: Evaluate if socioecological and biological factors, at the age of 8 years, are associated with lower level of physical activity (PA) 2 years later. Method: In a study cohort of 199 children aged 7.8±0.6 years, we used questionnaires and physical measurements to evaluate biological (eg, sex), social (eg, parental PA) and environmental (eg, school settings) factors. Objective PA was meas

Time Trends and Monthly Variation in Swedish Acute Stroke Care

Background and Purpose: Studies of monthly variation in acute stroke care have led to conflicting results. Our objective was to study monthly variation and longitudinal trends in quality of care and patient survival following acute stroke.Methods: Our nationwide study included all adult patients (≥18 years) with acute stroke (ischemic or hemorrhagic), admitted to Swedish hospitals from 2011 to 201

Bridging Boundaries: Challenges to integrated collaboration in design-driven innovation

This paper presents a pilot study of the collaborative interaction between industrial design and engineering design in a significant productdevelopment project at a major Swedish vehicle manufacturer. Since industrial and engineering design have different approaches to productdevelopment, they require careful integration to reach their full potential, to reach project goals, and to ensure the inno

From “We Didn’t Do It” to “We’ve Learned Our Lesson” : Development of a Typology of Neutralizations of Corporate Crime

When corporations are faced with accusations of crime, they usually find it necessary to justify their actions to the public, the media and their shareholders. Corporate self-defense, aimed at protecting a corporation’s image and legitimacy, belongs to a broader category of offenders’ denials and neutralizations.
