Translating community-based participatory research into broadscale sociopolitical change: insights from a coalition of women firefighters, scientists, and environmental health advocates

Sat, 23 Sep 2023 00:00:00 +0000

BackgroundWe report on community-based participatory research (CBPR) initiated by women firefighters in order to share successful elements that can be instructive for other community-engaged research. This CBPR initiative, known as the Women Worker Biomonitoring Collaborative (WWBC) is the first we are aware of to investigate links between occupational exposures and health outcomes, including breast cancer, for a cohort of exclusively women firefighters.MethodsIn order to be reflective of the experiences and knowledge of those most intimately involved, this article is co-authored by leaders of the research initiative. We collected leaders’ input via recorded meeting sessions, emails, and a shared online document. We also conducted interviews (N = 10) with key research participants and community leaders to include additional perspectives.ResultsFactors contributing to the initiative’s success in enacting broadscale social change and advancing scientific knowledge include (1) forming...

Impacts of electronic cigarettes usage on air quality of vape shops and their nearby areas

Sun, 20 Mar 2022 00:00:00 +0000

With the rapid growth of the electronic cigarette (e-cig) market, there is an increasing number of vape shops that exclusively sell e-cigs. The use of e-cigs in the vape shop is a primary source of indoor particles, which might transport to its nearby indoor spaces in the multiunit setting. In this study, six pairs of vape shops and neighboring businesses in Southern California were recruited for real-time measurements of particulate pollutants between February 2017 and October 2019. The mean (SD) particle number concentration (PNC) and PM_2.5 concentration in the studied vape shops were 2.8 × 10⁴ (2.3 × 10⁴) particles/cm³ and 276 (546) μg/m³, which were substantially higher than those in neighboring businesses and outdoor areas. In addition, 24-h time-weighted average (TWA) nicotine sampling was conducted in the six pairs and three additional pairs. Nicotine was detected in the air of all the studied vape...

Enhancing Print Journal Analysis for Shared Print Collections

Wed, 16 Jun 2021 00:00:00 +0000

The Western Regional Storage Trust (WEST), is a distributed shared print journal repository program serving research libraries, college and university libraries, and library consortia in the Western Region of the United States. WEST solicits serial bibliographic records and related holdings biennially, which are evaluated and identified as candidates for shared print archiving using a complex collection analysis process. California Digital Library’s Discovery & Delivery WEST operations team (WEST-Ops) supports the functionality behind this collection analysis process used by WEST program staff (WEST-Staff) and members.For WEST, proposals for shared print archiving have been historically predicated on what is known as an Ulrich’s journal family, which pulls together related serial titles, for example, succeeding and preceding serial titles, their supplements, and foreign language parallel titles. Ulrich’s, while it has been invaluable, proves problematic in several ways, resulting...

Effects of propylene glycol, vegetable glycerin, and nicotine on emissions and dynamics of electronic cigarette aerosols

Sat, 23 Jan 2021 00:00:00 +0000

An electronic cigarette (e-cig) generates aerosols by vaporizing the e-liquid, which mainly consists of propylene glycol (PG), vegetable glycerin (VG), and nicotine. Understanding the effects of e-liquid main compositions on e-cig aerosols is important for exposure assessment. This study investigated how the PG/VG ratio and nicotine content affect e-cig aerosol emissions and dynamics. A tank-based e-cig device with 10 different flavorless e-liquid mixtures (e.g., PG/VG ratios of 0/100, 10/90, 30/70, 50/50, and 100/0 with 0.0% or 2.4% nicotine) was used to puff aerosols into a 0.46 m³ stainless steel chamber for 0.5 h. Real-time measurements of particle number concentration (PNC), fine particulate matter (PM_2.5), and particle size distributions were conducted continuously throughout the puffing and the following 2-h decay period. During the decay period, particle loss rates were determined by a first-order log-linear regression and used to calculate the emission...

Effects of Electronic Cigarettes on Indoor Air Quality and Health

Mon, 10 Aug 2020 00:00:00 +0000

With the rapid increase in electronic cigarette (e-cig) users worldwide, secondhand exposure to e-cig aerosols has become a serious public health concern. We summarize the evidence on the effects of e-cigs on indoor air quality, chemical compositions of mainstream and secondhand e-cig aerosols, and associated respiratory and cardiovascular effects. The use of e-cigs in indoor environments leads to high levels of fine and ultrafine particles similar to tobacco cigarettes (t-cigs). Concentrations of chemical compounds in e-cig aerosols are generally lower than those in t-cig smoke, but a substantial amount of vaporized propylene glycol, vegetable glycerin, nicotine, and toxic substances, such as aldehydes and heavy metals, has been reported. Exposures to mainstream e-cig aerosols have biologic effects but only limited evidence shows adverse respiratory and cardiovascular effects in humans. Long-term studies are needed to better understand the dosimetry and health effects of exposures...

The WARC (Web ARChive) file format offers a convention for concatenating multiple resource records (data objects), each consisting of a set of simple text headers and an arbitrary data block into one long file.

A Metadata Kernel for Electronic Permanence

Sat, 16 Feb 2019 00:00:00 +0000

This paper presents a streamlined metadata record format designed to support the permanence of network discoverable objects. It starts with the Dublin Core consensus and distills out a subset of four semantic buckets − a metadata kernel − that balances the needs for adequate identification of persistent objects and for low cost metadata generation. To minimize the burden of creating, understanding, and manipulating data in those buckets, a very simple record format has been designed, called an Electronic Resource Citation (ERC). The basic ERC can be parsed by two lines of Perl code. Beyond permanence support, the ERC design suggests quite a new path for the ongoing development of simple metadata; readers familiar with the current evolutionary challenges may find the ERC to be simpler, and yet more complete, compact, extensible, and international than the Dublin Core.

The ARK Identifier Scheme: Lessons Learnt at the BnF and Questions Yet Unanswered

Sat, 16 Feb 2019 00:00:00 +0000

The Bibliothèque nationale de France (BnF) looks back at lessons learnt over a decade of implementing persistent identifiers (ARKs). Those lessons give an insight into what it means to maintain persistent identifiers in the mid-term. A systematic gap analysis between what is and what should be, especially in a Semantic Web context, lead to open questions about best practices and standards compliance.

Towards Electronic Persistence Using ARK Identifiers

Sat, 16 Feb 2019 00:00:00 +0000

The ARK (Archival Resource Key) is the only persistent naming scheme for internet information objects that squarely faces the service issues underlying practical electronic permanence. The ARK is a specially constructed, actionable URL encapsulating a globally unique identity that is independent of the current service provider. Each ARK is by definition bound to three things: (a) object access, (b) object metadata, and (c) a faceted commitment statement. These service bindings provide the best way for service providers to communicate their varied commitments to objects. It is for these reasons that the California Digital Library is pursuing the use of ARKs.

Nothing succeeds like success: An approach for evaluating digital preservation efficacy

Sun, 1 Jul 2018 00:00:00 +0000

Digital preservation encompasses the theory and practice ensuring purposeful future use of digital resources. But how can one tell whether it has been effective or not? The evaluation of preservation efficacy has two dimensions: trustworthiness of managerial programs and systems; and successful use of managed resources. While the former has received extensive attention, the latter has been little investigated. This stems from an insufficiently broad conceptualization of the preservation enterprise, which should be viewed expansively as facilitating meaningful human communication across time and concomitant cultural distance. Communicological analysis leads to a semiotic-phenomenological model for preservation-enabled communication cognizant of the elusive nature of use, which is inherently contingent with respect to time, place, person, and purpose. Preservation success is positioned as an individual, rather than universal value, with a benchmark evaluation of...

Theorizing success: Measures for evaluating digital preservation efficacy

Fri, 8 Jun 2018 00:00:00 +0000

Digital information is indispensable to contemporary commerce, culture, science, and education. No future understanding of a prior time in the digital age is possible without proactive preservation of our digital heritage. But how can one know whether or not that preservation has been effective? There are two primary assessments of digital preservation efficacy: trustworthiness of managerial systems and programs, and successful use of preserved resources. The first has received extensive treatment in the literature, but the second has been little investigated. This stems from a too narrow conceptualization of the preservation domain as synonymous with data management. Given that the goal of that management is to facilitate future use, and that use is inherently contingent with respect to time, place, person, and purpose, digital preservation should be seen more broadly as facilitating human communication across time. My research asks what measures can meaningful evaluate the efficacy...

Marijuana as a 'concept' flavour for cigar products: availability and price near California schools.

Mon, 4 Dec 2017 00:00:00 +0000

To assess the retail availability of cigar products that refer to marijuana and the largest package size of cigarillos available for ≤$1.

Trained data collectors conducted marketing surveillance in a random sample of licensed tobacco retailers that sold little cigars/cigarillos (LCCs) (n=530) near a statewide sample of middle and high schools (n=132) in California. Multilevel models examined the presence of marijuana co-marketing and cigarillo pack size as a function of school/neighbourhood characteristics and adjusted for store type.

Of stores that sold LCCs, approximately 62% contained at least one form of marijuana co-marketing: 53.2% sold cigar wraps marketed as blunt wraps, 27.2% sold cigarillos marketed as blunts and 26.0% sold at least one LCC with a marijuana-related 'concept' flavour. Controlling for store type, marijuana co-marketing was more prevalent in school neighbourhoods with a higher proportion of young residents (ages 5-17 years) and with lower...
