What Difference do Bystanders Make? The Association of Bystander Involvement with Victim Outcomes in a Community Sample

Objective: To fill gaps in the bystander literature by describing patterns of bystander involvement and associations between bystander involvement and victim outcomes across different types of emotional, physical, and sexual victimizations and to expand these considerations to a rural rather than urban sample. Method: Adults and adolescents (n = 1,703) were surveyed about bystander actions, bystander safety, and victim outcomes (injury, disrupted routine, fear level, and current mental health) for 10 forms of victimization. Results: Bystanders were present for roughly 2 thirds of most victimization types (59% to 67%), except sexual victimization (17%). Relatives were the most common bystanders of family violence and friends or acquaintances were the most common bystanders of peer violence. For all 10 victimizations, more bystanders helped than harmed the situation, but most commonly had no impact. Rates of bystander harm for sexual victimizations were higher than for other types. Especially for peer-perpetrated incidents, victim outcomes were often better when bystanders helped. Bystander safety (unharmed and unthreatened) was consistently associated with better victim outcomes. Conclusion: Bystanders witness the majority of physical and psychological victimizations. These data lend support to the premise of many prevention programs that helpful bystanders are associated with more positive victim outcomes. Bystander prevention should focus on the type of bystanders most commonly present and should teach bystanders ways to stay safe while helping victims

Particle Flux in the deep Sargasso Sea : the 35-Year Oceanic Flux Program time series

The definitive version was published in Oceanography 27, no. 1 (2014): 142–147, doi:10.5670/oceanog.2014.17.The Oceanic Flux Program (OFP) sediment trap time series, the longest running time series of its kind, has continuously measured particle fluxes in the deep Sargasso Sea since 1978. OFP results provided the first direct observation of seasonality in the deep ocean, and they have documented the tight coupling between deep fluxes and upper ocean processes and the intensity of biological reprocessing of sinking flux in the ocean interior. The synergy among OFP and other research programs co-located at the Bermuda time-series site has provided unprecedented opportunities to study the linkages among ocean physics, biology, and chemistry; particle flux generation; and particle recycling in the ocean interior. The OFP time series is beginning to reveal how basin-scale climatic forcing, such as the North Atlantic Oscillation, affects the deep particle flux.We gratefully acknowledge the National Science Foundation’s continuous financial support of the Oceanic Flux Program time series for the past 35 years, most recently by NSF grants OCE 1234294 and OCE 0927098

Unravelling the Dodecahedral Spaces

The hyperbolic dodecahedral space of Weber and Seifert has a natural non-positively curved cubulation obtained by subdividing the dodecahedron into cubes. We show that the hyperbolic dodecahedral space has a 6-sheeted irregular cover with the property that the canonical hypersurfaces made up of the mid-cubes give a very short hierarchy. Moreover, we describe a 60-sheeted cover in which the associated cubulation is special. We also describe the natural cubulation and covers of the spherical dodecahedral space (aka Poincar\'e homology sphere).Comment: 15 pages + 6 pages appendix, 7 figures, 4 table

The Worldwide Alzheimer\u27s Disease Neuroimaging Initiative: ADNI-3 updates and global perspectives

The Worldwide Alzheimer\u27s Disease Neuroimaging Initiative (WW-ADNI) is a collaborative effort to investigate imaging and biofluid markers that can inform Alzheimer\u27s disease treatment trials. It is a public-private partnership that spans North America, Argentina, Australia, Canada, China, Japan, Korea, Mexico, and Taiwan. In 2004, ADNI researchers began a naturalistic, longitudinal study that continues today around the globe. Through several successive phases (ADNI-1, ADNI-GO, ADNI-2, and ADNI-3), the study has fueled amyloid and tau phenotyping and refined neuroimaging methodologies. WW-ADNI researchers have successfully standardized analyses and openly share data without embargo, providing a rich data set for other investigators. On August 26, 2020, the Alzheimer\u27s Association convened WW-ADNI researchers who shared updates from ADNI-3 and their vision for ADNI-4

Hurricanes enhance labile carbon export to the deep ocean

The definitive version was published in Geophysical Research Letters 46 (2019): 10484–10494, doi:10.1029/2019GL083719.Tropical cyclones (hurricanes) generate intense surface ocean cooling and vertical mixing resulting in nutrient upwelling into the photic zone and episodic phytoplankton blooms. However, their influence on the deep ocean remains unknown. Here we present evidence that hurricanes also impact the ocean's biological pump by enhancing export of labile organic material to the deep ocean. In October 2016, Category 3 Hurricane Nicole passed over the Bermuda Time Series site in the oligotrophic NW Atlantic Ocean. Following Nicole's passage, particulate fluxes of lipids diagnostic of fresh phytodetritus, zooplankton, and microbial biomass increased by 30–300% at 1,500 m depth and 30–800% at 3,200 m depth. Mesopelagic suspended particles following Nicole were also enriched in phytodetrital material and in zooplankton and bacteria lipids, indicating particle disaggregation and a deepwater ecosystem response. Predicted climate‐induced increases in hurricane frequency and/or intensity may significantly alter ocean biogeochemical cycles by increasing the strength of the biological pump.This work and the Oceanic Flux Program time series were supported by the National Science Foundation Chemical Oceanography Program Grant OCE 1536644.

Radiation therapy planning with photons and protons for early and advanced breast cancer: an overview

Postoperative radiation therapy substantially decreases local relapse and moderately reduces breast cancer mortality, but can be associated with increased late mortality due to cardiovascular morbidity and secondary malignancies. Sophistication of breast irradiation techniques, including conformal radiotherapy and intensity modulated radiation therapy, has been shown to markedly reduce cardiac and lung irradiation. The delivery of more conformal treatment can also be achieved with particle beam therapy using protons. Protons have superior dose distributional qualities compared to photons, as dose deposition occurs in a modulated narrow zone, called the Bragg peak. As a result, further dose optimization in breast cancer treatment can be reasonably expected with protons. In this review, we outline the potential indications and benefits of breast cancer radiotherapy with protons. Comparative planning studies and preliminary clinical data are detailed and future developments are considered
