Sexual selection and life history interact to influence the evolution of paternal care.

Parental care is essential to offspring survival in many species. Understanding why males of some species provide care, whereas others do not, has received substantial attention. Previous research has found that sexual selection can favor paternal care, yet we still do not fully understand why sexual selection favors male care in some species but not others. It is also unclear when paternal care versus other preferred male trait(s) will be favored by sexual selection. We hypothesize that sexual selection can interact with basic life history to influence the conditions under which paternal care and/or another preferred male trait will be favored by sexual selection. We used a mathematical approach in which males alone provide parental care and exhibit a non-care trait that is preferred in mate choice. Using this approach, we demonstrate that life-history characteristics (stage-specific mortality, fertilization success, gamete numbers) can interact with sexual selection to influence the evolution of paternal care and/or a preferred non-care trait. In particular, whether (1) adult mortality, egg mortality, and fertilization success are high versus low and (2) a tradeoff exists between paternal care and a non-care preferred trait will influence whether selection most strongly favors additional paternal care or a non-care preferred trait. In general, we would expect strong selection for more male care when it is preferred in mate choice. In some cases, mate preferences for paternal care can inhibit selection for a preferred non-care trait. Mate preferences for paternal care can also broaden the life-history conditions under which we would expect the elaboration of male care to occur.

"I Can't Just Pull a Woman Out of a Hat": A Mixed-Methods Study on Journalistic Drivers of Women's Representation in Political News.

While the persisting issue of women's underrepresentation in political news partly arises from biases in the social reality, journalism plays a crucial role in mediating these biases. This study proposes a multilayered framework of gendered influences in journalistic news production to understand how journalistic factors exacerbate or mitigate women's media representation. Drawing from a mixed-methods design (content analysis, survey, interviews), journalists' own gender emerges as the strongest predictor of gendered representations. Women's underrepresentation is also influenced by professional roles but not by organizations' gender guidelines. We explore how journalists perceive these influences and discuss conceptual and practical implications.

'The Emperor's new clothes?' Healthcare professionals' perceptions of the nursing associate role in two UK National Health Service hospitals: A qualitative interview study.

Background: The introduction of nursing associates in England in 2017 as a professional 'bridging' role aimed to mitigate chronic staffing shortages, enable career progression of healthcare assistants and release registered nurses to provide more complex care. Limited evidence exists about the alignment between the identity and purpose of nursing associate roles described by the UK independent regulator, the Nursing & Midwifery Council, and the expectations, obligations, and team dynamics encountered in practice. Purpose: Investigate the perceptions of nursing associate roles through the views and experiences of role holders, registered nurses, and healthcare assistants. Setting: Two British National Health Service (NHS) Hospital Trusts in London, England (UK). Methods: For this registered service evaluation, data were collected via in-person, semi-structured interviews. Verbatim transcripts were coded inductively. An adapted framework analysis method, suitable for use with Excel, was applied to support the identification of cross cutting themes. We used the Standards for Reporting Qualitative Research checklist for reporting this study. Results: Eleven registered nurses, five nursing associates, and five healthcare assistants participated. Their experiences seldom reflected the policy vision of the nursing associate role in practice. Several participants likened the nursing associate role to the fable of the 'Emperor's New Clothes' in which expectations and reality diverge. With this over-arching theme, four sub-themes were identified: (1) preparedness of organisational infrastructure to support this role; (2) credibility of the role in practice; (3) perceived organisational "blindness" to the ambiguities of the role and (4) increasing task orientation and segmentation in care delivery. Conclusion: There is a discrepancy between the identity of the nursing associate role as imagined in the policy agenda and its reality in practice. There is a need for more protected and well-defined training, clear role boundaries, and accessible career progression pathways for nursing associates. Moreover, honest dialogue at an organisational and policy level must continue, so that the challenges and opportunities of the nursing associate role are properly realised.

The FXR1 network acts as a signaling scaffold for actomyosin remodeling.

It is currently not known whether mRNAs fulfill structural roles in the cytoplasm. Here, we report the fragile X-related protein 1 (FXR1) network, an mRNA-protein (mRNP) network present throughout the cytoplasm, formed by FXR1-mediated packaging of exceptionally long mRNAs. These mRNAs serve as an underlying condensate scaffold and concentrate FXR1 molecules. The FXR1 network contains multiple protein binding sites and functions as a signaling scaffold for interacting proteins. We show that it is necessary for RhoA signaling-induced actomyosin reorganization to provide spatial proximity between kinases and their substrates. Point mutations in FXR1, found in its homolog FMR1, where they cause fragile X syndrome, disrupt the network. FXR1 network disruption prevents actomyosin remodeling-an essential and ubiquitous process for the regulation of cell shape, migration, and synaptic function. Our findings uncover a structural role for cytoplasmic mRNA and show how the FXR1 RNA-binding protein as part of the FXR1 network acts as an organizer of signaling reactions.

Adjusting Parenting Roles and Work Expectations among Women with Children during COVID-19.

This study explores mothers' experiences during the COVID-19 pandemic with a focus on stressors, parenting roles, and work expectations. Qualitative analysis of open-ended interviews with a diverse group of 44 mothers in the United States generated two main themes: adjusting parenting roles and career concerns for mothers. Findings reveal that mothers have both internalized strong intra-family expectations to shoulder the primary responsibility for domestic labor and childcare in addition to completing their work obligations and experience institutional gender bias in the expectations that employers have for female employees. The interviews highlight lower expectations for fathers' contributions to parenting under pandemic conditions. Implications for research and policy are discussed with a particular focus on critiquing structures that may perpetuate gender disparities.

Anal Sexual Roles and Impacts on HIV Infection and Psychological Distress Among Men Who Have Sex With Men in China: A 14-Year Longitudinal Study.

Previous studies have shown that men who have sex with men (MSM) with different anal sexual roles, namely bottom, versatile, and top, are at different risk of HIV infection and psychological distress. However, the evidence was primarily derived from cross-sectional designs from Western countries, and it remains unclear how anal sexual roles change over a long time and their health impacts among MSM from Eastern countries. We aimed to describe the changes in anal sexual roles among a Chinese sample of MSM over 14 years and explore their effects on HIV infection, depression, anxiety, and suicidal ideation. Between 2009 and 2023, a longitudinal study was conducted on 373 MSM in Changsha, China, to assess their anal sexual roles, HIV infection, and psychological distress, including depression, anxiety, and suicidal ideation. Generalized linear models with a binomial probability was used to analyze the predictive effect of anal sexual roles on HIV infection and psychological distress. At baseline, 30.3% of MSM self-identified as bottom, 32.2% as versatile, and 37.5% as top, and these numbers changed slightly to 35.9%, 33.0%, and 31.1%, respectively, at follow-up (p = 0.131). From baseline to follow-up, 48 (12.9%) new HIV cases were identified. The prevalence of depression increased from 23.1 to 38.1% (p < 0.001), anxiety increased from 25.5% to 35.4% (p = 0.003), and suicidal ideation increased from 30.8 to 38.9% (p = 0.021). MSM with bottom and versatile roles were more likely to have HIV infection, depression, anxiety, and suicidal ideation than those with top roles. MSM's risk of HIV infection and psychological distress varies according to their anal sexual roles, suggesting that future HIV prevention and mental health improvement programs for MSM may benefit from providing targeted and individualized support based on their anal sexual roles, with a particular focus on those with bottom and versatile roles.

How Does Masculinity Play a Protective Role for Gay Men? The Mediation Effect of Mindfulness Between Gender Role and Mental Distress.

Masculinity is validated as a protective factor in mental health for gay population. However, potential mediators between masculinity and mental health remain unclear. Mindfulness, as one of the individual's traits has been proved to play an essential role on mental health. Yet the correlation between mindfulness and masculinity has barely been examined, and whether mindfulness could serve as a key mediator to explain the protective effect masculinity bringing to mental health for gay men remains unknown. To test this hypothesis, we recruited 210 gay men in China to conduct online questionnaires containing scales of FFMQ, BSRI, DASS-21 and demographic features. Based on mediation analysis, we found among gay men, mindfulness significantly mediates the negative relationship between masculinity and stress (SIE (standardized indirect effect) = -.20, 95% CI [-.28 -.11]), anxiety (SIE = -.17, 95% CI [-.26 -.09]) and depression (SIE = -.20, 95% CI [-.29 -.11]). Furthermore, by decomposing sub-dimensions of mindfulness, we found both "describing" and "acting with awareness" exhibit significant mediation effects between masculinity and mental distress. We further found "being analytical", one key sub-dimension of masculinity, positively correlates with mindful describing (r = .369, p < .001). Our results indicate that trait mindfulness serves as a core mediator between masculinity and mental health, the key trait in masculinity (being analytical) closely connects with the essential element of mindfulness (describing) and low in masculinity might undermine gay men's abilities of acting with awareness (staying focused). Our findings may also shed light on developing gay men-aimed mindfulness-based clinical interventions.

Gender roles as predictive factors on labor pain: a cross-sectional study.

Labor is a complex, subjective experience, and all factors that influence pain should be considered to ensure a comprehensive evaluation. This study aimed to determine whether gender roles were predictive of labor pain. The study has a descriptive and cross-sectional design. It was carried out in a delivery room of a city hospital in Turkey between September 2019 and September 2020. The study sample consisted of 231 primiparous women presenting for labor and delivery. Data were gathered with a descriptive characteristics form, Visual Analogue Scale and The Bem Sex-Role Inventory. Descriptive statistics and simple regression analysis were employed to analyze the obtained data. Regression analysis demonstrated that gender roles were predictive of labor pain in the latent, active, and transitional stages, but not in the second stage. Gender roles were most responsible for labor pain in the latent phase. Results of the study revealed that gender roles may be useful variables to predict women's labor pain, and contributed to the relevant literature. Nurses and midwives offering care for labor pain should consider gender roles as a factor affecting labor pain. It is also necessary to individualize the supporting care given during labor.

Roles and perspectives in supporting radiography student mental health: A qualitative exploration.

INTRODUCTION: University-based mental health services are crucial to supporting radiography students' mental health and addressing university mental health risk factors. This study aimed to identify factors causing mental health challenges among radiography students, understand their academic impact, and explore lecturers' potential roles in supporting students' well-being at a Zimbabwean tertiary institution. METHODS: A qualitative explorative study employing in-depth semi-structured interviews with 10 radiography students and eight educators was conducted. The interviews were recorded and transcribed verbatim using Otter.ai software. The data was then analyzed inductively using thematic analysis in Nvivo 12, following Braun and Clarke's six-step approach. RESULTS: Three themes were created that describe the factors causing mental health challenges among radiography students, their academic impact, and lecturers' potential roles in supporting students' well-being. The themes are i. Mental health challenges in diverse social, personal, and environmental landscapes ii. Coping and building resilience, and iii. Educator roles in holistic support for mental health and personal growth. A six-step "Cascade" model of the educator roles was proposed. CONCLUSIONS: The study highlights the complex mental health issues faced by radiography students, emphasizing the need for increased attention, resources, and support in academic environments. It highlights the importance of encouraging healthy coping strategies and cultivating a well-being culture, with educators playing a crucial role in fostering friendly environments and providing comprehensive support. Future research should investigate educators' ability to take on these roles while maintaining their current duties in Education 5.0.

Transformation: From (Trans-)Gender Roles to Profiles.

Combining a philosophical approach with empirical psychology, this essay investigates the relationship between "profilicity," the formation of identity in orientation to profiles, and gender identity. We discuss empirical research that indicates a significant difference between transgender identity in traditional (collectivist) and modern (individualist) societies. We suggest that this difference is due to a shift in the formation of gender identity away from gender roles and toward gender profiles. To substantiate this claim, we first outline a basic theoretical terminology of identity and gender. Then, we critically analyze the representation of gender, including transgender, in contemporary popular culture. Finally-with a descriptive, but not therapeutic intention-we discuss several case studies of identity formation of transgender people. We conclude that theoretical problems arising from historical shifts in gender identity formation, including transgender identity formation, are best conceptualized in terms of profilicity rather than in the still prevailing semantics of authenticity.

Content validation study on the Advanced Practice Role Delineation Tool.

BACKGROUND: Role understanding and practice standards become extremely important in countries that are developing and assessing nursing and advanced practice nursing (APN) roles. AIM: To describe the process and findings of a content validation study conducted on the Advanced Practice Role Delineation (APRD) tool in a Finnish context. DESIGN: A tool content validation study. METHOD: Between September and October 2019, three rounds of surveys (n = 9, n = 8, n = 5) were conducted to assess the content validity of the APRD tool. Furthermore, a thorough literature review was conducted in December 2020 to examine how the tool has been used and validated between January 2000 and December 2020. RESULTS: A 45-item amendment of the APRD tool was created. The Scale Content Validity Index Average of 0.97 reflects excellent content validity. A literature review of 15 studies revealed that the tool has been used by many researchers, yet there is limited research on its content and construct. CONCLUSION: The steps taken in this study were effective and may be replicated in other countries. Further studies are needed to validate the content and structure of the developed 45-item modification of the APRD tool.

(Re)Conceptualizing Sex and Gender in Physical Education through Social Role Theory.

The line between gender and sex has become increasingly muddled in recent scientific literature, including within physical education. Tensions surrounding this topic are ever-increasing and definitions of the two are rarely consistent. For improving conceptual clarity for research, we adopted the Social Role Theory to offer spaces for researchers to explore how these two terms differ and relate by laying out a cyclical framework of biological, sociological, and psychological components. Herein, we discuss the origins of the binary sex construct, anatomical brain/ cognition differences, and sex/gender role implications for education and physical education. In this conceptual paper, we confront the controversial topic in a content area that continues to be masculine-oriented with the purpose to conceptualize sex/gender in physical education research through clarifying the evolutionary bio-social spectrum. Offering a reconceptualization of gender as a multi-dimensional construct in physical education could inspire further curricular reform for the content to be more inclusive of all participants, learnable by all students regardless of sex and gender, and beneficial both mentally and physically to all learners.

"It's Your Own Fault": Factors Influencing Victim Blaming.

This study examined the association between victimization and victim blaming using a sample of n = 142 participants in a generalized linear mixed model (GLMM) with the influence of subject gender, victim stereotyping level, threat level, and victim gender for victim blaming. Belief in a just world was included in the model as a covariate. Mediation analyses were conducted with the degree of identifiability with the victim and attitudes toward traditional role models as explanatory approaches. In addition, acceptance of rape myths was considered. The GLMM analyses suggest that victim blaming by male subjects was significantly higher on average than by female subjects when all other predictors were held constant. As an explanatory approach for these effects of the subjects' gender on victim blaming, partial mediation was found with the degree of identification with the victim as a mediator. No main effects were found for the other influencing factors, but only a statistically significant three-way interaction. This indicates a differential effect of the level of stereotyping for male and female victims in conditions that end in high threat. The finding of the main effect of subjects' gender seems to be particularly important for the legal system, as it appears to make a difference in who is asked in terms of victim blameworthiness. This finding highlights the importance of considering a victim's personal characteristics and the need for future research with an additional focus on the characteristics of the sentencers to help clarify potential biases.

Evolutionary drivers of sex-specific parasite prevalence in wild birds.

Males and females often differ in ecology, behaviour and lifestyle, and these differences are expected to lead to sex differences in parasite susceptibility. However, neither the sex differences in parasite prevalence, nor their ecological and evolutionary drivers have been investigated across a broad range of taxa using phylogenetically corrected analyses. Using the most extensive dataset yet that includes 755 prevalence estimates from 151 wild bird species in a meta-analytic framework, here we compare sex differences in blood and gastrointestinal parasites. We show that despite sex differences in parasite infection being frequently reported in the literature, only Haemoproteus infections were more prevalent in females than in males. Notably, only seasonality was strongly associated with the sex-specific parasite prevalence of both Leucocytozoon and Haemoproteus, where birds showed greater female bias in prevalence during breeding periods compared to the non-breeding period. No other ecological or sexual selection variables were associated with sex-specific prevalence of parasite prevalence. We suggest that much of the variation in sex-biased prevalence could be idiosyncratic, and driven by local ecology and behavioural differences of the parasite and the host. Therefore, breeding ecology and sexual selection may only have a modest influence on sex-different parasite prevalence across wild birds.

Will AMPK be a potential therapeutic target for hepatocellular carcinoma?

Cancer is the disease that poses the greatest threat to human health today. Among them, hepatocellular carcinoma (HCC) is particularly prominent due to its high recurrence rate and extremely low five-year postoperative survival rate. In addition to surgical treatment, radiotherapy, chemotherapy, and immunotherapy are the main methods for treating HCC. Due to the natural drug resistance of chemoradiotherapy and targeted drugs, satisfactory results have not been achieved in terms of therapeutic efficacy and cost. AMP-Activated Protein Kinase (AMPK) is a serine/threonine protein kinase. It mainly coordinates the metabolism and transformation of energy between cells, which maintaining a balance between energy supply and demand. The processes of cell growth, proliferation, autophagy, and survival all involve various reaction of cells to energy changes. The regulatory role of AMPK in cellular energy metabolism plays an important role in the occurrence, development, treatment, and prognosis of HCC. Here, we reviewed the latest progress on the regulatory role of AMPK in the occurrence and development of HCC. Firstly, the molecular structure and activation mechanism of AMPK were introduced. Secondly, the emerging regulator related to AMPK and tumors were elaborated. Next, the multitasking roles of AMPK in the occurrence and development mechanism of HCC were discussed separately. Finally, the translational implications and the challenges of AMPK-targeted therapies for HCC treatment were elaborated. In summary, these pieces of information suggest that AMPK can serve as a promising specific therapeutic target for the treatment of HCC.

Design of New BLE GAP Roles for Vehicular Communications.

Bluetooth Low Energy (BLE) is a prominent short-range wireless communication protocol widely extended for communications and sensor systems in consumer electronics and industrial applications, ranging from manufacturing to retail and healthcare. The BLE protocol provides four generic access profile (GAP) roles when it is used in its low-energy version, i.e., ver. 4 and beyond. GAP roles control connections and allow BLE devices to interoperate each other. They are defined by the Bluetooth special interest group (SIG) and are primarily oriented to connect peripherals wirelessly to smartphones, laptops, and desktops. Consequently, the existing GAP roles have characteristics that do not fit well with vehicular communications in cooperative intelligent transport systems (C-ITS), where low-latency communications in high-density environments with stringent security demands are required. This work addresses this gap by developing two new GAP roles, defined at the application layer to meet the specific requirements of vehicular communications, and by providing a service application programming interface (API) for developers of vehicle-to-everything (V2X) applications. We have named this new approach ITS-BLE. These GAP roles are intended to facilitate BLE-based solutions for real-world scenarios on roads, such as detecting road traffic signs or exchanging information at toll booths. We have developed a prototype able to work indistinctly as a unidirectional or bidirectional communication device, depending on the use case. To solve security risks in the exchange of personal data, BLE data packets, here called packet data units (PDU), are encrypted or signed to guarantee either privacy when sharing sensitive data or authenticity when avoiding spoofing, respectively. Measurements taken and their later evaluation demonstrated the feasibility of a V2X BLE network consisting of picocells with a radius of about 200 m.

Genetic counselors outside of the genetics clinic: Roles, practices, and ethico-legal implications in light of lagging legal recognition across Canada.

Advances in medical genetics have led to a significant increase in demand for genetic services and expertise across almost all medical specialties. Genetic counselors (GCs) in Canada play key roles in genetic services both within and outside of the Genetics Clinic, while not being regulated or legally recognized as healthcare professionals (HCPs) in most provinces. Understanding whether GCs outside of the "traditional" Genetics Clinic influence patient care, their level of professional autonomy and supervisory structure is, therefore, important. In this study, we explore the current landscape of GC practice outside of the Genetics Clinic by describing positions, determining the professional scope of practice, as defined by the Canadian Association of Genetic Counselors (CAGC) and Canadian Board of Genetic Counseling (CBGC) core competencies, and by elucidating associated ethico-legal implications. An online survey was developed and distributed to GCs working with patient-related data in Canada in positions outside of the Genetics Clinic through the CAGC ListServ and accessed between March 5 and April 9, 2021. Thirty GCs were included in the study, with 16/30 in public healthcare system positions. Most respondents held roles with direct (11/30) and indirect (14/30) impact on patient care and management, and the majority reported performing their primary roles with minimal supervision (56%) or complete independence (36%). Most roles (22/25) elicited by respondents were considered to be within the GC scope of practice, except for administrative tasks and special projects. GCs were the only genetics-trained professional(s) in 8/30 of respondents' workplaces. The results of the current study support the value of GCs translatable skillset in positions beyond the Genetics Clinic, and outline ethico-legal implications for GCs, regulated HCPs, patients, and health institutions in the absence of legal recognition, including medical-legal liability and title protection. This study provides evidence in support of regulation of GCs as HCPs.

The roles and responsibilities of advanced practice nurses in intensive care units: A scoping review.

INTRODUCTION: Since the intensive care units are one of the most sensitive hospital settings and critically ill patients undergo various stressful factors that put their lives in danger, a more advanced level of nursing practice is imperative to accommodate these issues and provide optimal care of patients. OBJECTIVES: To review the literature describing the roles and activities performed by advanced practice nurses in intensive care units. REVIEW METHODS: We conducted a scoping review to search published articles using Scopus, PubMed, CINAHL (EBSCOhost), Science Direct, MEDLINE (EBSCOhost) and Cochrane Library during a 10-year period from 2013 to 2023. RESULTS: We identified 729 records, from which eleven articles were included in the review. We included six reviews and five original articles or research papers. With regard to the target area of our review, we used the information provided by these studies and categorized the contents related to the roles of advanced practice nurses in intensive care units into five sections, including direct practice, education and counseling, research, collaboration, and leadership. CONCLUSION: Advanced practice nurses are essential members of critical care team by playing various roles in practice, education, research, collaboration, and leadership, and therefore, they can increase patients' access to critical care and improve healthcare outcomes. The advancement of technology and complexity of care in intensive care units have led to the role expansion of these nurses which results in task-shifting between doctors and nurses. Therefore, it is considered essential for nursing and medical professionals to reach an agreement to establish standardized roles for advanced practice nurses.

Clarifying middle authorship contributions to reduce abuses in science publishing and assessment of top-ranked SJR biochemistry and pharmacology journals' authorship criteria.

So-called "middle authors," being neither the first, last, nor corresponding author of an academic paper, have made increasing relative contributions to academic scholarship over recent decades. No work has specifically and explicitly addressed the roles, rights, and responsibilities of middle authors, an authorship position which we believe is particularly vulnerable to abuse via growing phenomena such as paper mills. Responsible middle authorship requires transparent declarations of intellectual and other scientific contributions that journals can and should require of co-authors and established guidelines and criteria to achieve this already exist (ICMJE/CRediT). Although publishers, editors, and authors need to collectively uphold a situation of shared responsibility for appropriate co-authorship, current models have failed science since verification of authorship is impossible, except through blind trust in authors' statements. During the retraction of a paper, while the opinion of individual co-authors might be noted in a retraction notice, the retraction itself practically erases the relevance of co-author contributions and position/status (first, leading, senior, last, co-corresponding, etc.). Paper mills may have successfully proliferated because individual authors' roles and responsibilities are not tangibly verifiable and are thus indiscernible. We draw on a historical example of manipulated research to argue that authors and editors should publish publicly available, traceable contributions to the intellectual content of an article-both classical authorship or technical contributions-to maximize both visibility of individual contributions and accountability. To make our article practically more relevant to this journal's readership, we reviewed the top 50 Q1 journals in the fields of biochemistry and pharmacology, as ranked by the SJR, to appreciate which journals adopted the ICMJE or CRediT schools of authorship contribution, finding significant variation in adhesion to ICMJE guidelines nor the CRediT criteria and wording of author guidelines.
