K-stable equivalence for knots in Heegaard surfaces

Let K be a knot embedded in a Heegaard surface S for a closed orientable 3-manifold M. We define K-stable equivalence between pairs (S, K) and (S', K) in M, and we prove that any two pairs are K-stably equivalent in M if they have the same surface slope.Comment: 18 pages, 10 figure

Evaluating 'Prefer not to say' Around Sensitive Disclosures

As people's offline and online lives become increasingly entwined, the sensitivity of personal information disclosed online is increasing. Disclosures often occur through structured disclosure fields (e.g., drop-down lists). Prior research suggests these fields may limit privacy, with non-disclosing users being presumed to be hiding undesirable information. We investigated this around HIV status disclosure in online dating apps used by men who have sex with men. Our online study asked participants (N=183) to rate profiles where HIV status was either disclosed or undisclosed. We tested three designs for displaying undisclosed fields. Visibility of undisclosed fields had a significant effect on the way profiles were rated, and other profile information (e.g., ethnicity) could affect inferences that develop around undisclosed information. Our research highlights complexities around designing for non-disclosure and questions the voluntary nature of these fields. Further work is outlined to ensure disclosure control is appropriately implemented around online sensitive information disclosures

Effects of a Tailored Follow-Up Intervention on Health Behaviors, Beliefs, and Attitudes

Background: The high rates of relapse that tend to occur after short-term behavioral interventions indicate the need for maintenance programs that promote long-term adherence to new behavior patterns. Computer-tailored health messages that are mailed to participants or given in brief telephone calls offer an innovative and time-efficient alternative to ongoing face-to-face contact with healthcare providers. Methods: Following a 1-year behavior change program, 22 North Carolina health departments were randomly assigned to a follow-up intervention or control condition. Data were collected from 1999 to 2001 by telephone-administered surveys at preintervention and postintervention for 511 low-income, midlife adult women enrolled in the Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) program at local North Carolina health departments. During the year after the behavior change program, intervention participants were mailed six sets of computer-tailored health messages and received two computer-tailored telephone counseling sessions. Main outcomes of dietary and physical activity behaviors, beliefs, and attitudes were measured. Results: Intervention participants were more likely to move forward into more advanced stages of physical activity change (p = 0.02); control participants were more likely to increase their level of dietary social support at follow-up (p = 0.05). Both groups maintained low levels of reported saturated fat and cholesterol intake at follow-up. No changes were seen in physical activity in either group. Conclusions: Mailed computer-tailored health messages and telephone counseling calls favorably modified forward physical activity stage movement but did not appreciably affect any other psychosocial or behavioral outcomes

The Astropy Problem

The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python astronomy packages." For five years this project has been managed, written, and operated as a grassroots, self-organized, almost entirely volunteer effort while the software is used by the majority of the astronomical community. Despite this, the project has always been and remains to this day effectively unfunded. Further, contributors receive little or no formal recognition for creating and supporting what is now critical software. This paper explores the problem in detail, outlines possible solutions to correct this, and presents a few suggestions on how to address the sustainability of general purpose astronomical software

Even though I’m not an incel, I’m still an involuntary celibate: a journey in and out of inceldom.

Incels, or involuntary celibates, represent a sub-section of the manosphere: an informal confederacy of digital communities where men construct and strengthen anti-feminist/male hegemonic narratives. Inceldom represents a beta masculine identity, with members placing themselves at the bottom of a natural hierarchy. Bonded by a shared belief in their genetic inferiority and ensuing sexual marginalization, they are depressed and angered by the perceived permanence of their circumstances. In extreme cases, this outlook has been linked to acts of mass murder. The present study investigated how these digital communities attract young men, why they stay, and how they can be supported to leave. Online interviews were conducted with ex-incels to study why they joined incel communities, stayed in them, and later left. Thematic analysis identified six key themes, representing key stages across their journey in and out of inceldom: i) involuntary celibacy before inceldom; ii) "fucked by the world;" iii) failing with women = failing at life; iv) a safe space; vi) online de-radicalization; and vi) residue. Combined, they demonstrate how insular online spaces further isolate and radicalize socially inhibited young men

The ultimate test of self-discipline: lockdown and the NoFap community.

NoFap is a community of mostly heterosexual men abstaining from what they see as an addictive cycle of pornography, masturbation, and orgasm, induced by the exploitation of innate male urges by the pornography industry. In the general population, increased masturbation and consumption of pornography are associated with psychological factors including low affect, loneliness, and boredom, all of which may be exacerbated by the lockdown/social distancing measures adopted in response to the Covid-19 pandemic. The present study explores how the NoFap community has responded to the pandemic through discourse analysis of an online message board. We identify four key themes: i) I let go in lockdown, ii) the opportunity of lockdown, iii) testing the parameters of NoFap, and iv) community cohesion. Each is defined and discussed. Combined they illustrate a digital community struggling to honor its meritocratic masculine ideals in the face of challenging circumstances

PATRIC, the bacterial bioinformatics database and analysis resource

The Pathosystems Resource Integration Center (PATRIC) is the all-bacterial Bioinformatics Resource Center (BRC) (http://www.patricbrc.org). A joint effort by two of the original National Institute of Allergy and Infectious Diseases-funded BRCs, PATRIC provides researchers with an online resource that stores and integrates a variety of data types [e.g. genomics, transcriptomics, protein-protein interactions (PPIs), three-dimensional protein structures and sequence typing data] and associated metadata. Datatypes are summarized for individual genomes and across taxonomic levels. All genomes in PATRIC, currently more than 10 000, are consistently annotated using RAST, the Rapid Annotations using Subsystems Technology. Summaries of different data types are also provided for individual genes, where comparisons of different annotations are available, and also include available transcriptomic data. PATRIC provides a variety of ways for researchers to find data of interest and a private workspace where they can store both genomic and gene associations, and their own private data. Both private and public data can be analyzed together using a suite of tools to perform comparative genomic or transcriptomic analysis. PATRIC also includes integrated information related to disease and PPIs. All the data and integrated analysis and visualization tools are freely available. This manuscript describes updates to the PATRIC since its initial report in the 2007 NAR Database Issu
