Neural correlates of altered reward-driven attention in chronic pain and opioid use

Scientific Reports
While attentional processing of reward may be altered in chronic pain, the neural circuits underlying these alterations, and impact from opioid use have remained unclear. To investigate the neural representation of attentional processing in chronic pain,

SemEval-2018 Task 1: Affect in Tweets

International Workshop on Semantic Evaluation, 2018
We present the SemEval-2018 Task 1: Affect in Tweets, which includes an array of subtasks on inferring the affectual state of a person from their tweet. For each task, we created labeled data from English, Arabic, and Spanish tweets. The individual tasks

Microplastics affect sedimentary microbial communities and nitrogen cycling

Nature Communications, 2020
Microplastics are ubiquitous in estuarine, coastal, and deep sea sediments. The impacts of microplastics on sedimentary microbial ecosystems and biogeochemical carbon and nitrogen cycles, however, have not been well reported. To evaluate if microplastics

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

Population Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Affect and strategy use in independent language learning [PDF]

, 2008
Affect is about emotions and feelings, moods and attitudes, anxiety, tolerance of ambiguity and motivation. For some it is also connected with dispositions and preferences (Oatley & Jenkins, 1996).

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

Population Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

Population Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

Does Autoenrollment Affect Employer Contributions? [PDF]

, 2009
Summarizes research on how automatically enrolling employees in 401(k) plans in order to raise participation rates increases costs for employers and affects their matching contribution rates and, in turn, the retirement security of eligible ...
