Binary-constrained code-switching among non-binary French-English bilinguals

This paper presents data on non-binary French-English bilinguals’ metalinguistic analyses of their code-switching behavior in discussing their gender identities. Six non-binary French-English bilinguals were recruited for sociolinguistic interviews via Montréal-based LGBT+ organizations and asked about their experiences using non-binary French and English, especially how they describe themselves in each language. Participants’ preferences for using English to describe issues of gender identity reveals a particular type of topic-based code-switching is utilized in this community—a novel phenomenon that I have deemed Binary-Constrained Code-Switching, where participants switch out of an L1 (French) into an L2 (English) because they perceive their L1 as lacking the appropriate lexicon or grammatical features, specifically non-binary pronouns and gender agreement markers, to index their gender identities. In parallel to their dispreference for using French to describe their gender identities, participants’ preference for using English correlated with their perceptions of English as a more gender-neutral language than French, as well as a language with more linguistic resources—chiefly, vocabulary— to describe LGBT+ identities (c.f. queer). The data presented here not only supplement the primarily binary gender models found in extant studies of socially-motivated code-switching, but also provide greater evidence for the perceptual link between grammatical gender and social gender

Whistles of Sympatric Species of Bottlenose Dolphins (Tursiops truncatus) and Spotted Dolphins (Stenella frontalis) in the Bahamas: Acoustic Characteristics and Contextual Use

Bottlenose and spotted dolphins in the Bahamas frequently interact in social, socio-sexual, and aggressive encounters, and whistles are thought to play a key role in their communication. Concurrent vocal and behavioral recordings of wild sympatric species of Atlantic spotted dolphins (Stenella frontalis) and Atlantic bottlenose dolphins (Tursiops truncatus) were collected from three Bahamas populations, and the acoustic parameters, structure, and contextual use of their whistles were analyzed. The mean acoustic parameters of spotted dolphins in the Bimini and White Sand Ridge Bahamas populations were higher in frequency than those of bottlenose dolphins, but bottlenose dolphins produced whistles that had higher delta and maximum frequencies than those of spotted dolphins. Bottlenose dolphins produced proportionately more rise-type calls and convex calls than spotted dolphins did, and spotted dolphins displayed greater use of amplitude-modulated whistles. Differences in acoustic parameters between these two sympatric species may enable them to differentiate between conspecifics and non-conspecifics. As with all odontocete species examined so far, the two whistle parameters with the highest intraspecific variability in these populations were duration and number of inflection points, which may aid in individual differentiation or identification. Whistle acoustic parameters were also found to vary with behavioral context and group composition in spotted dolphins. Specifically, significantly more whistles produced by dolphin groups comprised mainly or entirely of calves and younger juveniles were amplitude modulated, and had significantly higher frequency parameters, especially during people-oriented behavioral states. Whistles with amplitude modulation and higher frequencies may provide cues about the age and emotive state of the animals producing them. Biphonation, the simultaneous production of two sounds, is a commonly occurring phenomena in the Bahamas Atlantic spotted dolphins. Bitonal whistles have very rarely been reported in any species of dolphin, but both burst-pulse whistles and bitonal whistles have been recorded in this population. Bitonal whistles are produced far more frequently by adults than by sexually immature dolphins, while burst-pulse whistles are produced more often in younger rather than older animals. Biphonal components of whistles may provide cues as to identity, age, and social role in spotted dolphin whistles

Mammography facilities serving vulnerable women have longer follow-up times.

ObjectiveTo investigate mammography facilities' follow-up times, population vulnerability, system-based processes, and association with cancer stage at diagnosis.Data sourcesProspectively collected from San Francisco Mammography Registry (SFMR) 2005-2011, California Cancer Registry 2005-2012, SFMR facility survey 2012.Study designWe examined time to biopsy for 17 750 abnormal mammogram results (BI-RADS 4/5), categorizing eight facilities as short or long follow-up based on proportion of mammograms with biopsy at 30 days. We examined facility population vulnerability (race/ethnicity, language, education), and system processes. Among women with a cancer diagnosis, we modeled odds of advanced-stage (≥IIb) cancer diagnosis by facility follow-up group.Data extraction methodsMerged SFMR, Cancer Registry and facility survey data.Principal findingsFacilities (N = 4) with short follow-up completed biopsies by 30 days for 82% of mammograms compared with 62% for facilities with long follow-up (N = 4) (P < 0.0001). All facilities serving high proportions of vulnerable women were long follow-up facilities. The long follow-up facilities had fewer radiologists, longer biopsy appointment wait times, and less communication directly with women. Having the index abnormal mammogram at a long follow-up facility was associated with higher adjusted odds of advanced-stage cancer (OR 1.45; 95% CI 1.10-1.91).ConclusionsProviding mammography facilities serving vulnerable women with appropriate resources may decrease disparities in abnormal mammogram follow-up and cancer diagnosis stage

Multi-mode question pretesting: Using traditional cognitive interviews and online testing as complementary methods

Questionnaire development, evaluation, and pretesting research is critical for ensuring that survey questions, materials, and data collection procedures produce the highest quality data possible. Interviewer-administered cognitive interviews is a common pretesting method used to collect rich, qualitative data. As technology has advanced, researchers can conduct similar research online in self-administered modes (Behr 2016), allowing for pretesting with larger samples. Each approach has strengths and limitations that researchers can leverage to address their pretesting goals. This research presents a multi-study, iterative project using traditional and online pretesting to evaluate new confidentiality language. Study 1 used traditional cognitive interviews to collect information on respondents’ qualitative reactions to, and comprehension of, the new language, but was limited by a small sample of prior survey respondents. Study 2 used online testing to help verify the previous findings with a larger sample, but was limited to hypothetical respondent behaviour. Study 3 used online testing over two waves of data collection to evaluate actual behaviour over time and expanded on the previous two studies by using an experimental design. We discuss the utility of using multiple pretesting methods to complement each other, providing research findings that would not be possible when using one alone

Women Behind Bars: Trends and Policy Issues

In the crusade to get tough on crime, policy makers have also gotten tough on women, drawing them into prisons in rapidly growing numbers. Today, incarcerated women are predominately poor, uneducated, and unskilled; are disproportionately African American and Latina young women with children; and have severe health and mental health problems. This article examines the characteristics and needs of these women and presents recommendations for their more humane and pragmatic treatment and for social policy that is relevant for the decarceration of this country\u27s soaring female prison population

Jasmonate-induced plant defenses and prey availability impact the preference and performance of an omnivorous stink bug, Podisus maculiventris

Many omnivorous insects are important biological control agents, and their success is influenced by both plant resistance and prey availability. The potential impact of these two factors is complicated by the fact that they may not be independent: Resistant plants also often support fewer herbivorous prey. We studied how lifetime development, growth, fecundity and preference of the omnivorous stink bug, Podisus maculiventris, was affected by jasmonate-induced plant defenses and amount of prey available. P. maculiventris survival was 70 % lower on high-resistance (jasmonate-overexpressing) plants compared to low-resistance (jasmonate-insensitive) plants. However, surviving P. maculiventris grew and achieved equal fecundity on low- and high-resistance plants. When given a choice, P. maculiventris preferred low-resistance plants, but did not differentiate between caterpillar prey reared on high- or low-resistance plants. Low prey availability impacted distinct aspects of P. maculiventris performance: Development time was lengthened, and nymphal and adult mass were reduced, but survival was not impacted. We did not detect any interactive effects between plant resistance and prey availability for any measure of P. maculiventris. Thus, we found remarkably compartmentalized impacts of plant resistance and prey availability for this omnivorous insect

Latinos and Cancer Information: Perspectives of Patients, Health Professionals and Telephone Cancer Information Specialists

Semi-structured interviews were conducted with 16 Latino cancer patients diagnosed in California; 10 health professionals from the San Francisco Bay Area and Fresno, California; and 10 Cancer Information Services (CIS) information specialists from the regional offices handling calls from Spanish-speakers. Interview guides were designed by the investigators to answer three main research questions: 1) How do Latinos obtain information about cancer and what types of information do they access?; 2) What sources of cancer information do they seek out and find credible?; and 3) What are the barriers and facilitators to Latinos obtaining cancer information? Stakeholders generally viewed health professionals as the most credible source of cancer information. All groups regarded family and friends as important sources of information. Patients and health professionals tended to differ on the value of print materials. Although patients found them generally useful, health professionals tended to view them as inadequate for meeting the informational needs of their Latino patients due to the challenge of low health literacy. Health professionals also tended to undervalue internet resources compared to patients and CIS specialists. All stakeholders viewed language, ethnic discordance and the impact on patients of the initial diagnosis as barriers to effective communication of cancer information. Health professionals and CIS specialists, but not patients, mentioned low literacy as a barrier. Our findings underscore the importance of the physician-patient relationship as a point of intervention to address the unmet informational and psychosocial needs of Latino cancer patients

Barriers to Eastern Oyster Aquaculture Expansion in Virginia

The eastern oyster once provided major societal and ecosystem benefits, but these benefits have been threatened in recent decades by large declines in oyster harvests. In many areas, recovery of oyster aquaculture faces significant societal opposition and spatial constraints limiting its ability to meet expectations regarding future food needs and provision of ecosystem services. In Virginia, oyster aquaculture has begun to expand, concurrent with an increase in subaqueous leased areas (over 130,000 acres of grounds are currently leased). Though private leases must in theory be used for oyster production, in practice, they can be held for other reasons, such as speculation or intentional exclusion of others. These factors have led to large variation over time and space in the use of leases in lower Chesapeake Bay; and privately leased grounds are now thought to be underutilized for oyster production. This research examined potential barriers to expansion of oyster aquaculture in Virginia. We first evaluated if a lack of space was limiting industry expansion and quantified temporal and spatial trends in the use and productivity of leases. Then, differences in used and non-used leases were investigated in relation to variables thought to be related to not in my backyard attitudes, congestion, speculation, local economic and environmental conditions. Finally, the performance of the Virginia leasing system was compared with those in other states along the U.S. East and Gulf Coasts. We found limited evidence for spatial constraints on aquaculture leasing, but strong evidence for social and regulatory inefficiencies. Although rates of lease use increased from 2006 to 2016, only 33% of leases were ever used for oyster production and about 63% of leaseholders reported no commercial harvests. Non-used leases tended to be smaller, and were found in more populated, high-income regions, consistent with both speculative and exclusionary uses. Virginia had the second lowest level of total production of cultured oysters per leased acre among the states on the East and Gulf Coasts of the United States. These results indicate that there is room for oyster aquaculture expansion in Virginia if societal, regulatory, and economic barriers can be reduced or if existing leased areas are used more efficiently

Photodegradation disproportionately impacts biodegradation of semi‐labile DOM in streams

Exposure of dissolved organic matter (DOM) to sunlight can increase or decrease the fraction that is biodegradable (BDOM), but conceptual models fail to explain this dichotomy. We investigated the effect of sunlight exposure on BDOM, addressing three knowledge gaps: (1) how fractions of DOM overlap in their susceptibility to degradation by sunlight and microbes, (2) how the net effect of sunlight on BDOM changes with photon dose, and (3) how rates of DOM photodegradation and biodegradation compare in a stream. Stream waters were exposed to sunlight, and then fed through bioreactors designed to separate labile and semi‐labile pools within BDOM. The net effects of photodegradation on DOM biodegradability, while generally positive, represented the balance between photochemical production and removal of BDOM that was mediated by photon dose. By using sunlight exposure times representative of sunlight exposures in a headwater stream and bioreactors colonized with natural communities and scaled to whole‐stream dynamics, we were able to relate our laboratory findings to the stream. The impact of sunlight exposure on rates of DOM biodegradation in streams was calculated using rates of light absorption by chromophoric DOM, apparent quantum yields for photomineralization and photochemical alteration of BDOM, and mass transfer coefficients for labile and semi‐labile DOM. Rates of photochemical alteration of labile DOM were an order of magnitude lower than rates of biodegradation of labile DOM, but for semi‐labile DOM, these rates were similar, suggesting that sunlight plays a substantial role in the fate of semi‐labile DOM in streams.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153758/1/lno11244.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153758/2/lno11244_am.pd
