Elucidating the impact of global climate change on aquatic ecosystems, particularly through phenological shifts in primary producers, is critical for understanding ecological resilience. Here, we focus on the phenological shifts in chlorophyll as a proxy for algae biomass and primary production in aquatic ecosystems, specifically in Lake Erie as well as concentrations of the toxin microcystin. By tracking temporal changes in each, we identified key phenological phases important to estimate duration, magnitude, and intensity of harmful algal blooms (HABs).

Validated instruments such as the Dynamic Appraisal of Situational Aggression (DASA), can aid risk assessment. However, limited attention has been paid to evaluating nurses' ability to administer risk assessment instruments.

Introduction: Intensive psychiatric care units can be challenging environments in which to build strong staff-patient relationships. Attachment theory may provide a useful model for strengthening relationships in this setting.
Aim: The aim of this study was to explore staff perceptions of the utility of attachment theory for understanding patient behaviour in the intensive psychiatric care setting.

Introduction: The Dynamic Appraisal of Situational Aggression (DASA) is used to appraise risk of imminent aggression in inpatient mental health settings.
Aim: We investigated whether individual patients' mean DASA scores over multiple consecutive time periods (a rolling DASA mean) improved predictive validity, beyond the ultimate DASA rating, and whether DASA ratings were associated with nursing intervention.
Method: Archival data were analysed using cox regression analyses.
The Dynamic Appraisal of Situational Aggression: Youth Version (DASA:YV) is a brief instrument, most often used by nurses and was specifically designed to assess risk of imminent violence in youth settings. To date, it has been recommended that DASA:YV scores are interpreted in a linear manner, with high scores indicating a greater level of risk and therefore need more assertive and immediate intervention. This study re-analyses an existing data set using contemporary robust data analytic procedures to examine the predictive validity of the DASA:YV, and to determine appropriate risk bands.
