Our Sherlockian eyes: the surveillance of vision
or this inter-disciplinary article, we undertook a pilot case study that eye-tracked the ‘Holmes Saves Mrs. Hudson’ sequence from the episode, A Scandal in Belgravia (Sherlock, BBC, 2012). This small-scale empirical study involved a total of 13 participants (3 males and 10 females, mean age was: 27 years), comprised of a mixture of academics and undergraduate students at La Trobe University in Melbourne, Australia. The article examines its findings through a range of threaded frames – neuroscience, forensics, surveillance, haptics, memory, performance-movement, and relationality – and uniquely draws upon the interests of the authors to set the examination in context. The article is both a reading of Sherlock and a dialogue between its authors. We discover that the codes and conventions of Sherlock have a direct impact on where viewers look but we also discover eyes emerging in the periphery of the frame, and we account for these ways of seeing in different ways
āLet me know when Iām neededā: Exploring the gendered nature of digital technology use for health information seeking during the transition to parenting
This paper presents results of a qualitative descriptive study conducted to understand parentsā experiences with digital technologies during their transition to parenting (i.e. the period from pre-conception through postpartum). Individuals in southwest Ontario who had become a new parent within the previous 24 months were recruited to participate in a focus group or individual interview. Participants were asked to describe the type of technologies they/their partner used during their transition to parenthood, and how such technologies were used to support their own and their family\u27s health. Focus group and interview transcripts were then subjected to thematic analysis using inductive coding. Ten focus groups and three individual interviews were conducted with 26 heterosexual female participants. Participants primarily used digital technologies to: (1) seek health information for a variety of reproductive health issues, and (2) establish social and emotional connections. The nature of such health information work was markedly gendered and was categorized by 2 dominant themes. First, āāLet me know when Iām neededāā, characterizes fathersā apparent avoidance of health information seeking and resultant creation of mothers as lay information mediaries. Second, āInformation Curationā, captures participantsā belief that gender biases built-in to popular parenting apps and resources reified the gendered nature of health and health information work during the transition to parenting. Overall, findings indicate that digital technology tailored to new and expecting parents actively reinforced gender norms regarding health information seeking, which creates undue burden on new mothers to become the sole health information seeker and interpreter for their family
Household Use of Financial Planners: Measurement Considerations for Researchers
Citation: Heckman, Stuart J. and Seay, Martin C and Kim, Kyoung Tae and Letkiewicz, Jodi, Household Use of Financial Planners: Measurement Considerations for Researchers (November 2, 2016). Financial Services Review, Vol. 25, p. 427-446, 2016.Using the Certified Financial Planner (CFP) Boardās definition of financial planning, this paper evaluates the validity of the measures of financial planner use in publicly available datasets. A review of Financial Services Review, Journal of Personal Finance, Journal of Financial Planning, Journal of Family and Economic Issues, Journal of Consumer Affairs, and Journal of Financial Counseling and Planning identified seven datasets that were commonly used to investigate financial planner use. Of these, the two most promising measures were found in the Survey of Consumer Finances and the National Longitudinal Study of Youth (1979). However, an evaluation of these measures raises significant concerns related to their validity. This article critically evaluates these measures and provides insights into the development of better measures of financial planner use for the future
Analysis of Team Science: Workshop Report on Airborne Transmission of Coronavirus ā
The goal of this research was to understand how information moved between different expert communities in order to describe how to facilitate better communication. We examined this through a case study discussing the public health relevance of airborne transmission of SARS-CoV-2, the virus underlying COVID-19. The main source of information was the National Academies report on the Airborne Transmission of SARS-CoV-2: Proceedings of a Workshop, which brought together experts in August 2020. We analyzed the workshop bibliography and attendee list to analyze who was involved and map the relationships between the co-authors to identify whose work influenced the conversation.
We also explored how experts communicated to create this workshop and the timeline of events leading up to it, by using news, scholarly articles, and Twitter posts to trace the discussion timeline. The aim of this project was to suggest guidelines for efficient and cohesive communication for team science. Through a detailed examination of this specific case study, we expected to map out what has worked well and what could be improved for communication between different communities. This information would be used in the future to support team science and optimal teamwork between expert communities.Ope
Differences in Reversion of Resistance Mutations to Wild-Type under Structured Treatment Interruption and Related Increase in Replication Capacity
The CPCRA 064 study examined the effect of structured treatment interruption (STI) of up to 4 months followed by salvage treatment in patients failing therapy with multi-drug resistant HIV. We examined the relationship between the reversion rate of major reverse transcriptase (RT) resistance-associated mutations and change in viral replication capacity (RC). The dataset included 90 patients with RC and genotypic data from virus samples collected at 0 (baseline), 2 and 4 months of STI.Rapid shift towards wild-type RC was observed during the first 2 months of STI. Median RC increased from 47.5% at baseline to 86.0% at 2 months and to 97.5% at 4 months. Between baseline and 2 months of STI, T215F had the fastest rate of reversion (41%) and the reversion of E44D and T69D was associated with the largest changes in RC. Among the most prevalent RT mutations, M184V had the fastest rate of reversion from baseline to 2 months (40%), and its reversion was associated with the largest increase in RC. Most rates of reversion increased between 2 months and 4 months, but the change in RC was more limited as it was already close to 100%. The highest frequency of concurrent reversion was found for L100I and K103N. Mutagenesis tree models showed that M184V, when present, was overall the first mutation to revert among all the RT mutations reported in the study.Longitudinal analysis of combined phenotypic and genotypic data during STI showed a large amount of variability in prevalence and reversion rates to wild-type codons among the RT resistance-associated mutations. The rate of reversion of these mutations may depend on the extent of RC increase as well as the co-occurring reversion of other mutations belonging to the same mutational pathway
The effects of carbon dots on immune system biomarkers, using the Murine Macrophage cell line RAW 264.7 and human whole blood cell cultures
Abstract: Carbon dots (CDs) are engineered nanoparticles that are used in a number of bioapplications
such as bioimaging, drug delivery and theranostics. The effects of CDs on the immune system have
not been evaluated. The effects of CDs on the immune system were assessed by using RAW264.7 cells
and whole blood cell cultures. RAW cells were exposed to CD concentrations under basal conditions.
Whole blood cell cultures were exposed to CD concentrations under basal conditions or in the
presence of the mitogens, lipopolysaccharide (LPS) or phytohaemmagglutinin (PHA). After exposure,
a number of parameters were assessed, such as cell viability, biomarkers of inflammation, cytokine
biomarkers of the acquired immune system and a proteome profile analysis. CDs were cytotoxic to
RAW and whole blood cell cultures at 62.5, 250 and 500 Āµg/mL, respectively. Biomarkers associated
with inflammation were induced by CD concentrations ā„250 and 500 Āµg/mL under basal conditions
for both RAW and whole blood cell cultures, respectively. The humoral immune cytokine interleukin
(IL)-10 was increased at 500 Āµg/mL CD under both basal and PHA activated whole blood cell culture
conditions. Proteome analysis supported the inflammatory data as upregulated proteins identified
are associated with inflammation. The upregulated proteins provide potential biomarkers of risk that
can be assessed upon CD exposure

Metabolic balance of coastal Antarctic waters revealed by autonomous pCO2 and ĪO2/Ar measurements
Author Posting. Ā© American Geophysical Union, 2014. This article is posted here by permission of American Geophysical Union for personal use, not for redistribution. The definitive version was published in Geophysical Research Letters 41 (2014): 6803ā6810, doi:10.1002/2014GL061266.We use autonomous gas measurements to examine the metabolic balance (photosynthesis minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations capture the development of a massive phytoplankton bloom and reveal striking variability in pCO2 and biological oxygen saturation (ĪO2/Ar) resulting from large shifts in community metabolism on time scales ranging from hours to weeks. Diel oscillations in surface gases are used to derive a high-resolution time series of net community production (NCP) that is consistent with 14C-based primary productivity estimates and with the observed seasonal evolution of phytoplankton biomass. A combination of physical mixing, grazing, and light availability appears to drive variability in coastal Antarctic NCP, leading to strong shifts between net autotrophy and heterotrophy on various time scales. Our approach provides insight into the metabolic responses of polar ocean ecosystems to environmental forcing and could be employed to autonomously detect climate-dependent changes in marine primary productivity.This study was supported by funds from the U.S. National Science Foundation (OPP awards ANT-0823101, ANT-1043559, ANT-1043593, and ANT-1043532) as well as support for PDT and ECA from the National Science and Engineering Research Council of Canada.2015-04-0
