Professional Representations of Collaboration in the Response to Intimate Partner Violence.

Purpose: Due to the complexity of intimate partner violence (IPV) and the many actors involved in its social and legal responses, there is a broad consensus that collaboration is essential if IPV is to be overcome. Few studies, however, have provided details as to how these collaborations occur. Rather, research on collaboration in IPV has typically focused on a series of factors facilitating and hindering it.

A gender study of the social representations of dating violence in Chilean adolescents.

Unlabelled: The experiences and viewpoints of adolescents as regards dating violence in southern countries remain poorly documented. It is thus difficult to have an overall understanding of the phenomenon. Based on social representation theory, this paper attempts to fill this gap by answering the question: What is dating violence for Chilean adolescents? Knowing what adolescents consider to be dating violence and the contextual elements that influence their perceptions is essential to developing effective prevention strategies.

Impact of a warm anomaly in the Pacific Arctic region derived from time-series export fluxes.

Unusually warm conditions recently observed in the Pacific Arctic region included a dramatic loss of sea ice cover and an enhanced inflow of warmer Pacific-derived waters. Moored sediment traps deployed at three biological hotspots of the Distributed Biological Observatory (DBO) during this anomalously warm period collected sinking particles nearly continuously from June 2017 to July 2019 in the northern Bering Sea (DBO2) and in the southern Chukchi Sea (DBO3), and from August 2018 to July 2019 in the northern Chukchi Sea (DBO4). Fluxes of living algal cells, chlorophyll a (chl a), total particulate matter (TPM), particulate organic carbon (POC), and zooplankton fecal pellets, along with zooplankton and meroplankton collected in the traps, were used to evaluate spatial and temporal variations in the development and composition of the phytoplankton and zooplankton communities in relation to sea ice cover and water temperature.

Annual cycle of downward particle fluxes on each side of the Gakkel Ridge in the central Arctic Ocean.

Two mooring arrays carrying sediment traps were deployed from September 2011 to August 2012 at ∼83°N on each side of the Gakkel Ridge in the Nansen and Amundsen Basins to measure downward particle flux below the euphotic zone (approx. 250 m) and approximately 150 m above seafloor at approximately 3500 and 4000 m depth, respectively. In a region that still experiences nearly complete ice cover throughout the year, export fluxes of total particulate matter (TPM), particulate organic carbon (POC), particulate nitrogen (PN), biogenic matter, lithogenic matter, biogenic particulate silica (bPSi), calcium carbonate (CaCO), protists and biomarkers only slightly decreased with depth.

Seasonal and latitudinal variations in sea ice algae deposition in the Northern Bering and Chukchi Seas determined by algal biomarkers.

An assessment of the production, distribution and fate of highly branched isoprenoid (HBI) biomarkers produced by sea ice and pelagic diatoms is necessary to interpret their detection and proportions in the northern Bering and Chukchi Seas. HBIs measured in surface sediments collected from 2012 to 2017 were used to determine the distribution and seasonality of the biomarkers relative to sea ice patterns. A northward gradient of increasing ice algae deposition was observed with localized occurrences of elevated IP25 (sympagic HBI) concentrations from 68-70°N and consistently strong sympagic signatures from 71-72.
