Environmental controls on the conversion of nutrients to chlorophyll in lakes.

Anthropogenic inputs of nitrogen and phosphorus to lakes have increased worldwide, causing phytoplankton chlorophyll concentrations to increase at many sites, with negative implications for biodiversity and human usage of lake resources. However, the conversion of nutrients to chlorophyll varies among lakes, hindering effective management actions to improve water quality. Here, using a rich global dataset, we explore how the relationship between chlorophyll-a (Chla) and nitrogen and phosphorus and inferred nutrient limitation is modified by climate, catchment, hydrology and lake characteristics.

Dissimilatory nitrate reduction pathways drive high nitrous oxide emissions and nitrogen retention under the flash drought in the largest freshwater lake in China.

Flash drought (FD) events induced by climate change may disrupt the normal hydrological regimes of floodplain lakes and affect the plant-microbe mediated dissimilatory nitrate reduction (DNR), i.e., denitrification, anammox and dissimilatory nitrate reduction to ammonium (DNRA), thus having important consequences for nitrous oxide (NO) emissions and nitrogen (N) retention.

Inflow-modulated inputs of dissolved organic matter fuel carbon dioxide emissions from a large hyper-eutrophic lake.

Terrestrial dissolved organic matter (DOM) is potentially reactive and, upon entering lake ecosystems, can be readily degraded to low-molecular-weight organic matter and dissolved CO. However, to date, there has been limited research on the links between long-term variation in the composition of DOM and CO emissions from lakes. Lake Taihu is a large, shallow, and hyper-eutrophic lake where DOM composition is strongly influenced by inputs from the rivers draining cultivated and urbanized landscapes.

Participatory research in child psychology & psychiatry: Embracing untidiness to break new ground.

We are pleased to present our Special Issue on Participatory Research. In this editorial, we outline how the disability rights movement has been instrumental to the development of participatory approaches, before giving consideration to some of the debates and criticisms associated with participatory research in practice. We summarise the contributions offered by the studies within this issue and propose four areas of consideration, drawn from the body of included research, to inform future developments.

Features of effective hospital fall prevention trials: an intervention component analysis.

Background: Falls in hospitals continue to burden patients, staff, and health systems. Prevention approaches are varied, as well as their success at preventing falls. Intervention component analysis (ICA) is useful in indicating important features associated with successful interventions in sets of trial with high heterogeneity.

Why Mental Health Clinicians are Not Engaging in Advance Care Planning with Older People with Schizophrenia and Other Psychotic Illnesses.

Purpose: To explore mental health clinicians' attitudes, experiences, and perceived barriers regarding Advance Care Planning (ACP) with older people (aged 55+) with schizophrenia/other psychotic illnesses.

Methods: Qualitative analysis of focus group interviews with multidisciplinary mental health clinicians from public mental health services in Sydney, Australia. A senior external clinician facilitated online focus groups exploring clinicians' attitudes, experiences, and perceived barriers to ACP using a semi-structured interview guide.

Dissolved organic carbon can alter coastal sediment phosphorus dynamic: Effects of different carbon forms and concentrations.

Coastal waters are receiving increasing loads of dissolved organic carbon (DOC), differing in structural complexity and molecular weights with potential different effects on the phosphorus (P) dynamics in these waters. This study conducted an in-situ investigation in Xiangshan Harbor, China, to explore the patterns of P release in response to DOC inputs. To further elucidate the underlying mechanisms behind the DOC-affected sediment P release, a two-month mesocosm experiment was undertaken with coastal sediment (Xiangshan Harbor) to which acetate, glucose, and humic acid (representing the fermentation product, the simple available carbon, and the refractory humic-like carbon sources, respectively) were separately added to the overlying water at dosages of 0, 5, 10, and 20 mg C L.

Metaphor as methodology: Methodological reflections on visualizing the dementia journey.

Metaphors to describe and understand dementia have been used in Western culture for many years. However, the ways in which people living with dementia and care partners use metaphors and symbols to illustrate and give meaning to their own experiences has been less understood. In this paper we explore the use of metaphor as methodology-- a way to support people living with dementia and their care partners in reflecting on and sharing their experiences of dementia.

The quality and safety of using generative AI to produce patient-centred discharge instructions.

Patient-centred instructions on discharge can improve adherence and outcomes. Using GPT-3.5 to generate patient-centred discharge instructions, we evaluated responses for safety, accuracy and language simplification.

The relationship of compliance with immediate and delayed suggestibility and types of resistant behavioral responses in children aged 10-15 years.

This study examined the relationship of compliance with immediate and delayed suggestibility and types of resistant behavioral responses (RBRs) in 454 children (10-15 years) using the Gudjonsson Suggestibility Scale (GSS 2) and a slightly adapted version of the Gudjonsson Compliance Scale (GCS). The GCS was found to have satisfactory internal consistency with this age group. Immediate suggestibility and delayed suggestibility were significantly correlated (small effect size).

Periodically asymmetric responses of deep chlorophyll maximum to light and thermocline in a clear monomictic lake: Insights from monthly and diel scale observations.

Deep chlorophyll maximum (DCM), a chlorophyll peak in the water column, has important implications for biogeochemical cycles, energy flow and water surface algal blooms in deep lakes. However, how an observed periodically asymmetric DCM response to environmental variables remains unclear, limiting our in-depth understanding and effective eco-environmental management of deep lakes. Based on both monthly field investigations in 2021 and diel continuous observations in 2021-2023 in clear, monomictic Lake Fuxian, Southwest China, the temporal dynamics and drivers of DCM were examined and periodic features of DCM were found, with a formation period (FP, February-July) and a weakening period (WP, August-December).

Improvement of water quality through coordinated multi-trophic level biomanipulations: Application to a subtropical emergency water supply lake.

Artificial emergency water source lakes have been built in most cities in the middle and lower reaches of the Yangtze River, China, to ensure water safety for residents. However, these new ecosystems are prone to algal blooms or other degraded water quality conditions. A newly built water supply lake in the lower reaches of the Yangtze River was selected as a model system to test whether the coordinated manipulation of fish and submerged macrophyte communities could enhance ecosystem function and quality.

Support roles, carer burden, and decision-making preferences of carers of older adults with cancer.

Introduction: Older adults with cancer value the perspectives of significant others and their carers regarding decision-making about treatment. Understanding the support provided by carers, and their perspectives on involvement in treatment decision-making, can help us improve our communication with patients and their supports. We aimed to describe the roles, burden, and decision-making preferences of carers of older adults with cancer.

Virtual Reality / Augmented Reality (VR/AR) Approach to Develop Social and Communication Skills in Children and Adolescents with Autism Spectrum Disorders Without Intellectual Impairment.

Background: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects a significant proportion of the world's population, particularly children and adolescents. The sensory processing issues can be an evidence-based target for therapeutic/corrective interventions by controlling the intensity and targeted replacement of maladaptive sensory stimuli with neutral stimuli using virtual reality or augmented reality.
