‘Harsh’ SoMa vs ‘Beige’ Castro: The cross-modal construction of contrasting femininities in queer San Francisco

The study of gender in sociolinguistic variation has long concerned the ways linguistic variables pattern with binary gender identities like male and female, with the implicit assumption that masculine individuals will use variants that index masculinity, and feminine individuals will use variants that index femininity. The emerging field of trans linguistics has built upon insights from queer linguistics and challenged the idea that there must be a one-to-one correspondence between linguistic variants and gender identities. Studies of transgender speakers have illuminated that indexing gender is a process of bricolage, where multiple variables collaborate, and only one needs to index gender in a particular way for the speaker's overall semiotic construction to carry that gendered meaning. Here, I investigate cross-modal bricolage, by exploring how visual gender presentation and three different linguistic variables come together to construct contrasting feminine styles among San Francisco drag queens. Linguistic patterns and aesthetic choices illuminate that bricolage involves a semiotic division of labor, in which only some signs (or modalities) need to index gender to give the overall style that gendered meaning. Concurrently, other signs can contribute qualia to a style's overall qualic cloud, that distinguish the style from others in the semiotic landscape. This exploration illuminates the role of the body in conditioning the indexical potential of linguistic signs, destabilizes monolithic essentializations of trans linguistic practice, and acknowledges the varied ways that gender non-normative identity can manifest across communities.

Physical activity and sedentarism among non-binary gender identified university students

Abstract Background Physical inactivity (PA) and sedentary behavior (SB) are modifiable risk factors for non-communicable diseases (NCDs). Data indicates that non-binary gender identified people find it difficult to perform PA, this is a disadvantage for them to reach their full health potential. Methods Students were selected by convenience sampling to complete a survey between October-November 2023. A validated PA questionnaire was included. PA and SB were classified into 4 levels: Active but sedentary, extremely sedentary, physically active and discreetly active. Data were analyzed using Statistical Package for the Social Sciences (SPSS). Results Out of 32 students did not identified themselves as binary gender. In our sample, 28,1% (vs 12.9% binary students) don’t do PA. Of those doing PA, 52,2% don’t meet World Health Organization recommendations. Among those who perform PA, there no difference in the amount of minutes/week of moderate or intense physical activity performed. Regarding SB, 93,8% spend >6 hours/day in SB (vs 84.7% binary students, mean 7,82 vs 8,75, Sg. 0,032). When grouped into PA/SB categories 65,6% (vs 40,5%) were extremely sedentary in contrast to 1,4% physically active (vs 8.8%). Conclusions In Spain, 1 in 4 young people does not identify with the male/female categories. In our sample, physical inactivity and sedentarism are higher among those who do not identify as male/female. Once they commit to physical activity, there is no difference in the time spent between those who meet the WHO recommendations. More research is needed to understand the reasons for these differences and ensure barrier-free access to healthy lifestyle habits on campus. Key messages • Non-binary gender identified students are less physically active and more sedentary than their peers. • Once they commit to physical activity recommendations, there are no differences among their performance.

Co-administration of COVID-19 and flu vaccines in healthcare workers: results from three campaigns

Abstract The COVID-19 pandemic, along with seasonal influenza, highlights the need for innovative public health strategies. Co-administering COVID-19 and influenza vaccines offers advantages for healthcare workers (HCWs), streamlining vaccination efforts and enhancing public health resilience. Recent evidence supports the safety and efficacy of this approach, endorsed by health authorities worldwide. However, its acceptance remains a concern. This study explores HCWs’ acceptance of vaccine co-administration in three campaigns post the introduction of the anti-SARS-CoV-2 vaccine. During three consecutive flu seasons from October 2021 to January 2024, a cross-sectional study was conducted in a large Italian teaching hospital. Data for 2021/2022, 2022/2023 and 2023/2024 were compared, focusing on healthcare workers present in all datasets. McNemar’s test examined changes in acceptance of co-administration. In addition, a conditional logistic regression model was designed to assess the determinants of co-administration through the vaccination campaigns in the three years. During these vaccination campaigns 7457 HCWs were observed (62.78% women, median age 43). Co-administration surged, particularly in 2022/2023, showing a 280.71% increase, consistent across all professional categories (p < 0.001). Controlling for gender and professional category, acceptance of coadministration showed a significant association respectively with “open days” twice a month (OR 2.9 CI [2.7; 3.6]) and a hospital vaccination clinic two days a week on weekdays (OR 4.5 CI [4.1; 5.4]) compared to conducting vaccinations at a clinic open everyday during the campaign period; no association was highlighted with age. This study investigates a facet of an increasingly significant topic, demonstrating that co-administering vaccines for SARS-CoV-2 and influenza is emerging as an effective strategy in annual vaccination campaigns, thanks to its safety and the streamlining of logistical and organizational processes. Key messages • The co-administration of vaccines offers a promising strategy to enhance vaccination rates among healthcare workers. • By identifying factors influencing acceptance, it aims to inform targeted interventions for maximizing vaccine uptake and public health resilience.

The decline of feminine gender: a cross-dialectal study of seven Norwegian dialects

This paper presents a cross-dialectal study of grammatical gender in Norwegian nominal phrases. Specifically, we investigate the decline of the feminine gender in three age groups across seven different dialects. The dialects vary in their morphological richness of gender marking: some dialects traditionally have more distinctive marking of the feminine gender. With an elicited production experiment, we investigate gender marking on the indefinite determiner and the definite suffix. We find that feminine gender is in decline in all dialects, but there are clear differences between the locations and between age groups. The feminine indefinite determiner ei is replaced by the masculine en at different rates and to a different degree in the various dialects. We furthermore find that the feminine definite suffix -a is retained in all locations except for Stavanger. We argue that the decline of the feminine gender can be explained by an interplay between the morphological richness of the given dialect and dialect contact. The former helps to retain the feminine as a separate category, while the latter accelerates the loss of the feminine.

Removing the Binary: An Exploration on the Impact Language has on Our Gender Perception

Language, as a reflection of societal values and beliefs, wields the power to shape perceptions of gender, often perpetuating a binary understanding through grammatical gender systems. The influence of the generic masculine and masculine norm within languages with dense grammatical gender reinforces this binary, marginalizing communities and centralizing power within the masculine form. Despite these challenges, endeavours towards gender neutrality within grammatical gender languages offer hope, particularly in their potential to benefit marginalized groups like the LGBTQ+ community. However, while recent advancements demonstrate potential for gender neutrality within language, the possibility of achieving a genuine ‘gender-free’ language remains a question, especially within grammatical gender languages and beyond. In order to begin answering this question, one needs to understand the concept of ‘gendered language’ and how it has impacted our perception of gender throughout history. It is also necessary to analyse how recent linguistic adjustments impact the LGBTQ+ community and the changes in attitudes towards non-binary spaces. By comparing attitudes towards gender in grammatical gender and genderless languages, we gain insight into the intricate relationship between language and societal norms. To do that one needs to look at the contemporary languages such as English, Spanish and Swedish, which are undergoing gender-neutral adaptations within the core lexicon and grammar. In addition to indigenous languages that have historically included a form of gender neutral language. In essence, this examination of language and gender dynamics offers the conclusion that it is possible to remove gender from language, yet cannot change the impact that gendered language has already had on society’s perception of gender.

Insomnia symptoms in children and adolescents: screening for sleep problems with the two-item Sleep Condition Indicator (SCI-02)

BackgroundSleep problems are common in young people. Yet brief screening measures to identify those most in need of an intervention are lacking. This study investigated the potential of the two-item Sleep Condition Indicator (SCI-02) for screening insomnia symptoms in children and adolescents. We sought to establish whether there are distinct subgroups with different sleep profiles and whether subgroup membership varied with gender and school year group.MethodsStudents (school years 5–13; typical age 9–18 years) in England completed the OxWell Student Survey in 2021. Sleep measures included: SCI-02, sleep onset latency (SOL), sleep duration, daytime sleepiness, and worry disrupting sleep. Latent profile analysis and multinomial logistic regression explored sleep profiles and predicted class membership.ResultsIn total, 29,304 participants answered sleep items. Of these, 95% provided binary gender (n = 27,802, 55% female) for analyses. Five sleep profiles emerged. The profiles, labelled “good”, “moderate”, or “poor” sleepers, vary by sleep quality – which includes time taken to fall asleep (SOL), amount of sleep (sleep duration), and the disruption of sleep due to worry. The profiles are then further differentiated by high levels of daytime sleepiness – labelled “sleepy”. “Good Sleepers” (18,355, 66%), “Moderate Sleepers” (4825, 17.4%), “Moderate Sleepy Sleepers” (1250, 4.5%), “Poor Sleepers” (1037, 3.7%) and “Poor Sleepy Sleepers” (2335, 8.4%). Probable insomnia rates (SCI-02 ≤ 2) were high in both poor sleeper profiles (70–80%) compared with other profiles (0%) and the sample overall (9%). Compared with “Good Sleepers”, all other profiles were mostly female. Daytime sleepiness – the defining characteristic of the sleepy sleeper profiles – was more common in secondary school participants than primary school.ConclusionsThe SCI-02 is an efficient, two-question measure to screen for potential sleep problems in young people. Sleep disruption was high: one in ten were experiencing poor sleep. Females and adolescents appeared more vulnerable to poor sleep and daytime sleepiness. The SCI-02 has the potential for use in school and community contexts to identify children and adolescents who may benefit from support managing their sleep.

The influence of grammatical gender on the conceptualization of the world: A systematic literature review

Many recent studies on grammatical gender and linguistic relativity overlook the neuter, simplifying the issue to a binary gender system. This study critically and systematically reviews research from the past decade, following the PRISMA protocol. The findings reveal a significant downward trend in the number of studies conducted over the past four years and a bias toward German and English. Additionally, languages with threegender systems are often inaccurately represented by excluding the neuter, limiting generalizability. These implications affect both research on linguistic relativity and genderrelated disciplines. The lack of attention to neuter gender and the recent reduction in the number of studies raise concerns about the comprehensiveness of current research approaches and highlight the need for more inclusive and refined methodologies moving forward.

Gender and race disparities in the evaluation of COVID-19 impact statements for tenure and promotion candidates

ABSTRACT The COVID-19 pandemic disrupted research productivity for many faculty members. As a result, many US universities began asking promotion and tenure candidates to create COVID-19 impact statements in hopes of mitigating the negative impact of these disruptions on tenure decisions. However, little is known about how such impact statements might be evaluated by promotion and tenure committees. This study examined whether such statements might be evaluated differently based on the gender and racial/ethnic categories of the faculty that submit them. Specifically, current US faculty were asked to evaluate hypothetical tenure dossiers that varied in race/ethnicity (Black/Latinx/White) and binary gender (Male/Female). Results indicated that female candidates were evaluated more favorably than male candidates. Specifically, participants thought that female candidate’s disruptions were more understandable, that their COVID-19 impact statements should be given more weight, and that they were more likely to vote to promote female candidates. There were no significant differences across candidates by race/ethnicity. The unexpected pattern of results suggests more research is needed to understand why such patterns emerged.

Ideological origins of resistance against gender‐inclusive language reforms: Singular they as a de‐gendering or multi‐gendering strategy

AbstractGender is traditionally conceptualized as a binary construct, which is reflected in the use of binary‐gendered third‐person pronouns. Gender‐inclusive pronouns such as singular they challenge this conceptualization, which can evoke resistance against their use. Singular they can be used generically when gender is unknown (de‐gendering), or to specifically highlight an individual's non‐binary gender identity (multi‐gendering). The different uses of singular they can threaten different ideological convictions and impact the use and perception of the pronoun. Experiment 1 (N = 599) showed that in de‐gendering contexts, participants preferred to use singular they but in multi‐gendering contexts they preferred binary pronouns. Social identification with one's gender group, RWA and binary gender views predicted less use of singular they in both contexts. In Experiment 2 (N = 199), participants evaluated sentences with singular they in de‐gendering and multi‐gendering contexts. Overall, sentences with singular they in de‐gendering contexts were more positively evaluated. SDO predicted less positive evaluations of they in de‐gendering contexts, while RWA and binary gender views predicted less positive evaluations of they in multi‐gendered contexts. The findings provide important knowledge in understanding ideological motivations for resistance against gender‐inclusive language.

An Annotated WWII Underwater Archaeology Bibliography

AbstractWith four decades of WWII underwater archaeology publications, the time is nigh to create a comprehensive bibliography and conduct an analysis of trends within the growing subfield. This paper presents a decade-by-decade analysis of academic publications accessible through a number of search engines and databases. It analyzes the papers through the categories of author gender, heritage type, region, and focus. Finally, it provides the data set by which this analysis was accomplished in a comprehensive bibliography.

Linguistic Hermeneutical Injustice

ABSTRACT Grammatical gender languages mark gender on every noun and agreement target such as adjectives and pronouns. While the norm for personal nouns provides that the term’s grammatical gender corresponds to its referent’s gender, in certain circumstances, a discrepancy arises between the term and its referent’s gender. Taking Italian as a case study, I identify four such circumstances: reference to non-binary people, women and non-binary professionals in traditionally male-dominated fields, generic or unknown individuals and mixed-gender groups. Among these, I distinguish between usage discrepancies, which depend on how speakers (mis)use language, and structural discrepancies, which depend on structural features of the language. The latter is the case for reference to non-binary people as Italian lacks a grammatical gender corresponding to non-binary gender identities. I focus on this case and argue that it conveys a problematic representation of gender, giving rise to a specific instance of hermeneutical injustice: structural discrepancies depend on a gap in collective interpretative resources (namely, the lack of an appropriate grammatical gender) and put non-binary people at an unfair disadvantage in making sense of their social experiences. As I show, the effects of structural discrepancies possess all the hallmarks of hermeneutical injustice.

Utilizing drawings to understand how our backgrounds and experiences change our plant mental models

Societal Impact StatementOur culture, life experiences, and the places we live teach us about the world around us and the plants within it. This information gives each individual distinct mental models. By delving into plant mental models of young adults, this study offers insights into the complex landscape of plant knowledge, with a special emphasis on Indigenous communities. Beyond broadening our understanding, these findings provide valuable resources for educators and researchers striving to bridge the gap in plant literacy. Moreover, the methods used offer a blueprint for similar investigations globally, which will foster a deeper understanding of plant awareness across diverse populations.Summary Plant mental models, or what people think about when they think of a given plant, give insight into a person's knowledge and understanding of plants. However, little to no research has been conducted on plant mental models of young adults or comparing mental models across demographics. This study assessed college students' plant mental models in the demographic categories of race, gender, rurality, and college type (tribal vs. non‐tribal), as well as experience in art, photography, and plant identification, to determine the impact of these factors on plant mental models. A total of 697 students from three tribal and three non‐tribal colleges enrolled in a specific introductory biology course participated. Participants completed four drawings, which represented their mental model of a plant, flower, grass, and tree. They also completed a short survey about demographics and experience with art, photography, and plant identification. Tree drawings had the most detail, and grass drawings had the least. Gender was the only demographic factor that impacted the detail drawn, with females including more detail for flowers and trees and males for grass. Surprisingly, experience with art, photography, and plant identification did not impact the detail included in the drawings. Overall, participants plant mental models across demographics were simplistic and lacked detail, potentially indicating a lack of plant awareness.

An ERP-based comparison of gender representations elicited by generic masculine role nouns and the German gender star form

There is an ongoing debate about the linguistic gender forms that should be used to elicit fair mental representations of all genders. While most languages with grammatical gender traditionally use the masculine form to refer to people in a gender-independent way, numerous empirical studies have demonstrated that this form leads to a male bias in mental representations. In German, the so-called gender star form has been proposed as an alternative to the masculine form, aimed at better representing persons with nonmale gender identities. To provide empirical data on this claim, we compared the neural processing mechanisms elicited by the gender star form with those elicited by the generically intended masculine form during reference resolution. Participants in the present ERP study read sentence pairs in which a group of people was introduced with a role noun in one of the two gender forms and then revealed to be partly comprised of men or women. Following the masculine form, anaphoric references to women (vs. men) resulted in an increased ERP amplitude in the P600 range. In contrast, following the gender star form, the P600 amplitude was increased for references to men (vs. women), albeit in a slightly different spatio-temporal range. The present data thus indicate that the gender star form and the generically intended masculine form impose partially different demands on the syntactic operations performed by the brain during reference resolution but that, in the end, neither form elicits gender-balanced mental representations of men and women in German.

Effects of the French grammatical gender system on bilingual adults' perception of objects

Abstract This study extends the line of linguistic relativity research by assessing the effect of the French grammatical gender system on French speakers' and learners' perception of objects. Four groups of 140 adults (English monolinguals, French monolinguals, English–French bilinguals and French–English bilinguals; N = 35 each) rated 32 selected objects' gender by assigning them a masculine/feminine voice on a slider. We also assessed the participants' second-language (L2) proficiency. Multilevel modelling results revealed that French monolinguals and English–French bilinguals rated objects' gender in line with the French grammatical gender system. The effect of French on perception was not reduced by acquiring English, as French–English bilinguals performed on par with French monolinguals. Moreover, the effect was independent of L2 proficiency. These findings suggest that learning a gendered L2 affects the perception of objects – thus supporting the linguistic relativity hypothesis.

Job satisfaction of multidisciplinary staff working in intensive care units: a cross-sectional study in Qatar

Background/Aims Job satisfaction is an important contributor to the efficacy and success of organisations. An intensive care unit is a highly skilled area of healthcare that can be a physically and mentally challenging environment for staff, potentially impacting job satisfaction. This study aimed to assess job satisfaction levels among multidisciplinary staff members working in the intensive care units of a hospital in Qatar and evaluate how this is affected by sociodemographic and employment factors. Methods This was a cross-sectional, quantitative study that used a survey method. A total of 142 intensive care unit nurses, physicians and allied health professionals were recruited via random sampling from a tertiary hospital in Qatar. The Minnesota Satisfaction Questionnaire (short form) was used to collect data on respondents' intrinsic, extrinsic and overall job satisfaction levels, using statements scored with 5-point Likert scales. The survey also collected data on respondents' gender, age, job category and years of experience working in intensive care. Data were analysed using Shapiro-Wilk tests, Mann-Whitney U tests, Kruskal–Wallis tests and analysis of variance. Mean overall job satisfaction scores were classified as low (<3.00), moderate (3.00–3.99) or high (>4.00). A P value of <0.05 indicated statistical significance. Results The mean overall job satisfaction score was 3.82 out of 5.00, indicating moderate satisfaction. There were strong correlations between job satisfaction and both intrinsic (0.940) and extrinsic (0.894) satisfaction. There was a significant difference in job satisfaction levels depending on respondents' years of experience working in intensive care units (P=0.0477), with those who had less than 10 years of experience having the highest job satisfaction levels and those with 20–24 years' experience having the lowest job satisfaction levels. There were no significant differences between the job satisfaction levels of participants in different gender, age and job categories. Conclusions This study suggests that intensive care unit staff with more years of experience may have lower job satisfaction than those with fewer years of experience. Healthcare organisations should consider implementing targeted interventions to enhance job satisfaction, such as opportunities for professional development, recognition programmes, mentorship programmes, stress management workshops and efforts to improve work-life balance.

Poverty Reduction and Family Functioning: Results from an Experimental Study in Sub-Saharan Africa

AbstractThe study tests the effect of poverty-reduction intervention on family functioning reported by AIDS-orphaned children in extended families in Southern Uganda by asking two questions: (1) based on children’s reports, how does poverty reduction intervention affect family functioning? and (2) to what extent do these effects vary by a child’s gender and orphanhood status? Informed by the social causation theory, family stress model, and asset theory, the study aims to address the existing knowledge gap on effects of poverty reduction interventions on family functioning in low-income families caring for AIDS orphaned children in Uganda. We ran multilevel regression models using longitudinal data collected in a cluster-randomized controlled trial from N = 1410 children (n = 621 boys and n = 789 girls) recruited from 48 rural primary schools in Uganda. Survey data was collected every 12 months over the course of 5 years. The average age of children at enrollment was 13 years. We found significant positive effects of the intervention on family cohesion, family communication, and child-caregiver relationship. Effects vary by child’s gender and orphanhood category. Intervention improves family communication for boys, while improving family cohesion and quality of child-caregiver relationship for girls. Single maternal orphans reported improved family communication, while single paternal orphans reported improved child-caregiver relationship. Poverty reduction interventions are important to improve family functioning for low-income families. Variations by child’s gender and orphanhood status have not been reported in previous studies, and our findings underscore the importance of continued research in this area.

The use of mnemonics techniques in teaching german grammar

The article deals with the specifics of teaching grammatical structure of the German language. Particular attention is paid to the use of mnemonic techniques designed to facilitate the processes of perception and memorization of new information, as well as to facilitate the usage of already studied grammar rules. Mnemonic techniques used when working with the category of gender of nouns, temporary forms, the morphological structure of lexical units of the German language are described separately.

Grammatical gender universalities underlying uniform mental representations of the world: Myth or reality?

The subject of grammatical gender and cognition has been continuously examined in psycholinguistics, wherein findings show essential support for gender congruency effects, suggesting that grammar lends matrices for speakers’ mental representations. Based on these psycholinguistic data, this study offers an innovative vista of investigation that combines typological and cognitive linguistic approaches. Its purpose lies in determining whether grammatical gender patterns sanction cross-linguistic universality in conceptualising entities as male or female, and whether grammatical gender universalities have semantic motivation. This research reveals universal tendencies in grammatical gender affiliation of the analysed nouns in 32 two and three gender languages belonging to different groups of the Indo-European, Indo-Iranian and Afro-Asiatic language families. From a cognitive perspective, these findings testify to the identical mental images of the entities denoting artefacts, natural phenomena and abstract concepts in speakers of the languages under consideration. Furthermore, grammatical gender universalities manifest certain semantic dimensions involving the motives associated with masculine or feminine and symbolic suggestions of the Woman archetype. As per the data from cognitive poetics, grammatical gender universalities become objects of special stylistic choices emerging as personified images of symbolic relevance in gender and non-gender languages.

Digging into Old English Legal Compounds

Word-formation in Old English has long been subject to several important studies, both from a theoretical and textual. Special attention has been given to compounding especially as a means to cope with the new concepts and notions present in Latin texts. Although often quoted, compounds in the Anglo-Saxon laws has been so far neglected. The present paper aims to partially fill the gap. Focussing on the early legal codes, from Æthelberht to Ine, we will categorise compounds in laws in a sort of typology and analyse them according their formal features. The difficulty in the determination of the semantic relationship between their constituents lead us to the hypothesis that, due to the close intertwining between law and its society, compounds are a mirror either backwards previous stages of the language (e.g. drihtinbeag ‘fine for slaying a freeman’ where drihtin retains its pre-Christian meaning) or forwards to future changes (e.g. the loss of grammatical gender, as in liblac ‘witchcraft’), but are also the results of a long process to develop a legal terminology. Therefore, to understand them one has to dig into each individual law.

Perception of voice cues and speech-in-speech by children with prelingual single-sided deafness and a cochlear implant

Voice cues, such as fundamental frequency (F0) and vocal tract length (VTL), help listeners identify the speaker's gender, perceive the linguistic and emotional prosody, and segregate competing talkers. Postlingually implanted adult cochlear implant (CI) users seem to have difficulty in perceiving and making use of voice cues, especially of VTL. Early implanted child CI users, in contrast, perceive and make use of both voice cues better than CI adults, and in patterns similar to their peers with normal hearing (NH).In our study, we investigated the perception and use of voice cues in children with single-sided deafness (SSD) who received their CI at an early age (SSD+CI), in an attempt to bridge the gap between these two groups. The SSD+CI children have access to bilateral auditory information and often receive their CI at an early age, similar to CI children. They may also have dominant acoustic representations, similar to CI adults who acquired hearing loss at a later age. As such, the current study aimed to investigate the perception and use of voice cues by a group of nine early-implanted children with prelingual SSD. The study consisted of three experiments: F0 and VTL discrimination, voice gender categorization, and speech-in-speech perception. In each experiment, the results of the SSD group are compared to children and adults with CIs (for their CI ear) and with typical hearing (for their NH ear).Overall, the SSD+CI children had poorer VTL detection thresholds with their CI compared to their NH ear, while their F0 perception was similar across ears. Detection thresholds for both F0 and VTL with their CI ear was comparable to those of bilaterally implanted CI children, suggesting that SSD+CI children do not only rely on their NH ear, but actually make use of their CI. SSD+CI children relied more heavily on F0 cues than on VTL cues for voice gender categorization, with cue weighting patterns comparable to those of CI adults. In contrast to CI children, the SSD+CI children showed limited speech perception benefit based on F0 and VTL differences between the target and masker speaker, which again corresponded to the results of CI adults. Altogether, the SSD+CI children make good use of their CI, despite a good-hearing ear, however, the perceptual patterns seem to fall in-between those of CI children and CI adults. Perhaps a combination of childhood neuroplasticity, limited experience with relying only on the CI, and a dominant acoustic representation of voice gender explain these results.
