Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

A War for Freedom: Slavery and the Emancipation Proclamation.

This paper examines the real effects of the Emancipation Proclamation, as it technically freed no slaves. It explores the events and legislation that led up the issuance of the Emancipation Proclamation as well as the reactions to and effects of the proclamation's release. This paper delves into the role of slave in the Civil War, both as "contraband" and soldiers, and the conflict that resulted from these roles. The research ultimately enters the debate on who freed the slaves. Some historians argue that the slaves freed themselves, while other argue that they were freed by the Civil War and President Lincoln. Based on primary and secondary source research, the paper combines these two ideas into an independent judgment on this question, concluding that slaves provided the pressure to force Lincoln's hand, but the act of emancipation was still ultimately issued by Lincoln, so he should be credited with freeing the slaves

Getting the big picture: supporting comprehension and learning in search

ABSTRACT This position paper contributes to the development of a research agenda on searching as an informal learning process by applying an established theory of comprehension and learning to the problem of web search. We present a conceptual framework for searching as learning based upon Kintsch's [10] ConstructionIntegration Model of text comprehension. Drawing upon this model, we identify and provide a rationale for a number of user and content factors that are likely to be associated with learning while searching: prior knowledge, motivation, knowledge actualization and text coherence. Some implications for the design of web search systems are described

Building infrastructures for university-community knowledge exchange : The Role of Information Professionals and Literacy Educators : Panel

This panel argues that information professionals and literacy educators play an important bridging role between universities and community groups and stakeholders. We describe the context of university-community knowledge exchange, which is increasingly expected, but remains under-supported and under-theorised, and consider new opportunities that exist to support and build capacity in researchers and communities to co-create, share, and use information. We focus on the training and professional development needed to position information professionals and literacy educators as knowledge brokers, and innovative projects that demonstrate their value and potential in this role.Arts, Faculty ofLibrary, UBCNon UBCInformation, School ofReviewedFacult

Searching for Relevance in the Relevance of Search

Abstract. Discussion of relevance has permeated the information science literature for the past 50+ years, and yet we are no closer to resolution of the matter. In this research we developed a set of measures to operationalize the dimensions underpinning Saracevic's manifestations of relevance. We used an existing data set collected from 48 participants who used a web search engine to complete four search tasks that represent four subject domains. From this study which had assessed multiple aspects of the search process -from cognitive to behavioural -we derived a set of measures for cognitive, motivational, situational, topical and system relevances. Using regression analysis, we demonstrate how the measures partially predict search success, and additionally use factor analysis to identify the underlying constructs of relevance. The results show that Saracevic's five manifestations may be merged into three types that represent the user, system and the task

Are They Buying It? United States Consumers’ Changing Attitudes toward More Humanely Raised Meat, Eggs, and Dairy

This survey research sampled 1000 US (United States) consumers of meat, eggs, and dairy on their attitudes towards the welfare of farm animals and the willingness to pay for products with trustworthy welfare certifications. Most respondents (70%) reported paying attention to labels that indicate how the animals were raised and 78% believed there should be an objective third party to ensure farm animal welfare. The weighted average of the marginal willingness to pay for products raised under a trustworthy welfare certification was $0.79 for eggs (a 32$0.96 for 1 lb. of chicken breast (a 48% premium). In addition, 57% of respondents reported they would be likely to choose a restaurant because it serves welfare-certified animal products and are also willing to pay ≥$5.00 extra per entrée. These findings suggest that many US consumers, particularly millennials, would be willing to seek out higher welfare products if they trust the label claims
