Dirty South Feminism: The Girlies Got Somethin’ to Say Too! Southern Hip-Hop Women, Fighting Respectability, Talking Mess, and Twerking Up the Dirty South
Creators: name: Johnson, Adeerya
Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2021

description: Within southern hip-hop, minimal credit has been given to the Black women who have curated sonic and performance narratives within the southern region. Many southern hip-hop scholars and journalists have centralized the accomplishments and masculinities of southern male rap performances. Here, dirty south feminism works to explore how agency, location, and Black women’s rap (lyrics and rhyme) and dance (twerking) performances in southern hip-hop are established under a contemporary hip-hop womanist framework. I critique the history of southern hip-hop culture by decentralizing male-dominated and hyper-masculine southern hip-hop identities. Second, I extend hip-hop feminist/womanist scholarship that includes tangible reflections of Black womanhood that emerge out of the South to see how these narratives reshape and re-inform representations of Black women and girls within southern hip-hop culture. I use dirty south feminism to include geographical understandings of southern Black women who have grown up in the South and been sexually shamed, objectified and pushed to the margins in southern hip-hop history. I seek to explore the following questions: How does the performance of Black women’s presence in hip-hop dance localize the South to help expand narratives within dirty south hip-hop? How can the “dirty south” as a geographical place within hip-hop be a guide to disrupt a conservative hip-hop South through a hip-hop womanist lens?

description: Severe alterations of Cacium-Phospate metabolism are frequently associated with chronic kidney diseases. High levels of Phospate and low levels of vitamin D in subjects affected by chronic kidney disease are, in many cases, correlated with high risk of mortality. For this reason, administration of vitamin D represents the elective treatment. Nevertheless, vitamin D in itself induces a variety of side effects which in many cases can be avoided by the administration of vitamin D analogues. In this study we treated murine cardiomyocytes with different concentrations of vitamin D and paricalcitol (one of its analogues) for 48 hours. Cell morphology, cell proliferation, intracellular Calcium deposition, and cAMP level were investigated respectively by light microscopy, immunoenzymatic assay and Von Kossa staining. Results show that, in comparison to paricalcitol, vitamin D induces stronger side effects on cardiomyocytes (such as cell proliferation, morphological changes, activation of signal transduction pathways). From our data emerges that paricalcitol induces less stressful effects on murine cardiomyocytes in comparison to what observed with vitamin D treatment.

description: Background Realistic pre-treatment expectations are important and have been associated with post-treatment health related quality of life (HRQOL). Patient expectations are greatly influenced by physicians, as they are the primary resource for information. This study aimed to explore the communication practices of physicians regarding treatment outcomes for patients with spinal metastases, and physician experiences with patients’ pre-treatment expectations. Methods An international qualitative study using semi-structured interviews with physicians routinely involved in treating metastatic spine disease (spine surgeons, radiation and medical oncologists, and rehabilitation specialists) was conducted. Physicians were interviewed about the content and extent of information they provide to patients with spinal metastases regarding treatment options, risks and treatment outcomes. Interviews were transcribed verbatim and analyzed using a thematic coding network. Results After 22 interviews data saturation occurred. The majority of the physicians indicated that they currently do not establish patients’ pre-treatment expectations, despite acknowledging the importance of these expectations. Spine surgeons often believe that patient expectations are disproportionate. Physicians expressed they manage expectations by detailing the most common risks and providing a broad but nonspecific overview of treatment outcomes. While the palliative intent seems clear to the physicians, their perception is that the implications of a palliative treatment remains elusive to most patients. Conclusion This study highlights the current gap in patient-physician communication regarding expectations of treatment outcomes of patients with spinal metastases. These results warrant further research to improve communication practices and determine the effect of patient expectations on patient reported outcomes in this population.

description: This thesis offers seminal contributions to macroradical chemistry. This work proposed a new approach to making conductive epoxies predicated on stable radicals. The first to successfully demonstrate synthetic techniques towards this idea; systematically employ magnetic alignment to tune material properties and utilized magnets during polymerization to differentiate material structures with X-ray scattering analysis. Furthermore, this contribution demonstrates the combined techniques of rheology and X-ray scattering data in characterizing supercapacitor materials. Finally, this thesis argues that surface electromagnetism could complement radical-bearing coatings rendered antifouling.

Hydrogen production

description: In recent years, hydrogen production and storage has attracted a lot of attention in both academia and industry due to its variety of applications in the energy sector. In this review, we attempt to list various methods of producing hydrogen from different sources of materials followed by the description of most recent developments in the materials perspective. We explain the role of nanotechnology in making the hydrogen production  technology a viable and cost effective process. The chemical reaction cycle, mechanism and configurations of various methods of hydrogen production are elaborated in Part I of this thesis.  Among the materials for chemical methods, aluminum could be utilized as an efficient and environmental friendly energy carrier via the production of hydrogen from water. However, it requires the reaction between aluminum and water to be complete, controllable and does not require the involvement of acids and/or alkali. Such direct reaction between aluminum and neutral water, once considered impractical due to the  passivation of aluminum surface in water, is enabled with the relatively recent use of catalytic gallium-based liquid alloys. In this paper we have examined the roles of  different elements (Ga, In, Sn, Zn, Bi) in this type of alloy and how their compositions affect the aforementioned reaction between aluminum and water. Besides the compositions of alloys, we have also studied the activation process between the liquid alloys and aluminum powders, as well as the storage process both before and after the activation. The rate of hydrogen production from each aluminum-water reaction was  measured as a function of time. The whole research is discussed in Part II of this thesis.  As photocatalysts for water splitting, CuBO2, CuAlO2, CuBO2/TiO2 heterojunction and CuAlO2/TiO2 heterojunction are synthesized and tested. All these  materials exhibit positive water-splitting capability with a solution environment of 0.05M Na2S·9H2O as a hole scavenger and 0.1M NaOH as a pH modifier under simulated AM 1.5 standard sun light. The group with heterojunction CuAlO2/TiO2 shows an average  hydrogen production rate of 0.509 mmol/min, 6.33% higher than the CuAlO2 group. The group with CuBO2 shows an average 0.979 mmol/min hydrogen production rate, the highest rate among all groups, 104.38% higher than the CuAlO2 group. The details of our work on photoelectrolysis are studied in Part III of this thesis.

description: Efficient and effective Dissemination, Exploitation, and Communication (DEC) will be essential in helping to achieve FEAST’s strategic objectives. FEAST is designed to create a paradigm shift towards food systems that are fairer, healthier, and more environmentally friendly for all actors, particularly vulnerable populations.

Our pathway to impact will begin by working through a Multi Actor Approach (MAA) to leverage the results and outputs from FEAST to ensure broad-scale strategic dissemination of the project’s findings and key messages, enabling their uptake and integration in future strategies and practices developed by local, regional and national governments, and simultaneously engaging the general public (e.g. consumers, citizens, etc.), production/supply side actors and young professionals in the implementation of such strategies - thus inspiring each target group to move upwards in the engagement pyramid, and further exploiting FEAST’s potential to build capacity.

This document provides an update to FEAST’s DEC plan based on progress from M6-M17 of the project (the first version of FEAST’s DEC plan is available on Zenodo (https://doi.org/10.5281/zenodo.11370487).  The updated DEC plan follows the same structure as the initial document and has been updated with concrete examples of the implementation of specific DEC activities.

description: We present a systematic ab initio study of the low-lying states in beryllium isotopes from 7Be to 12Be using nuclear lattice effective field theory with the N3LO interaction. Our calculations achieve good agreement with experimental data for energies, radii, and electromagnetic properties. We introduce a novel, model-independent method to quantify nuclear shapes, uncovering a distinct pattern in the interplay between positive and negative parity states across the isotopic chain. By combining Monte Carlo sampling of the many-body density operator with a novel nucleon-grouping algorithm, the prominent two-center cluster structures, the emergence of one-neutron halo, complex nuclear molecular dynamics such as π orbital and σ orbital, emerge naturally.

description: The travel industry faces persistent challenges in delivering integrated, personalized solutions despite technological advancements. This research presents Travelin - a modern web application leveraging React.js and Perplexity API to streamline travel planning through artificial intelligence. Unlike conventional platforms, Travelin combines dynamic itinerary generation with cultural insights using a modular frontend architecture built on Vite, TypeScript, and Tailwind CSS.

 

The system replaces traditional optimization algorithms with Perplexity's natural language processing capabilities to create adaptable travel plans based on user preferences. While initial development focuses on responsive UI/UX foundations, the architecture is designed for future integration of predictive analytics and real-time booking systems. Key innovations include a component-based interface for itinerary management, AI-powered destination suggestions through Perplexity's generative capabilities, and themeable design patterns supporting diverse user needs.

 

This implementation demonstrates how lightweight AI integration can enhance travel planning without complex backend infrastructure. By prioritizing developer experience through modern tooling (ESLint, Lucide React) and maintainable code practices, the project establishes a scalable foundation for progressive enhancement. Early testing indicates significant potential for reducing planning time through AI-assisted recommendations while maintaining user control over final decisions.

 

This project demonstrates how AI can revolutionize the travel industry by addressing gaps in personalization and planning. By combining dynamic itinerary optimization, trend forecasting, and integrated booking, the system enhances user experience and simplifies travel organization.

description: Background: We determined antibodies to the pandemic influenza A (H1N1) 2009 virus in children to assess: the incidence of (H1N1) 2009 infections in the 2009/2010 season in Germany, the proportion of subclinical infections and to compare titers in vaccinated and infected children. Methodology/Principal Findings: Eight pediatric hospitals distributed over Germany prospectively provided sera from in- or outpatients aged 1 to 17 years from April 1st to July 31st 2010. Vaccination history, recall of infections and sociodemographic factors were ascertained. Antibody titers were measured with a sensitive and specific in-house hemagglutination inhibition test (HIT) and compared to age-matched sera collected during 6 months before the onset of the pandemic in Germany. We analyzed 1420 post-pandemic and 300 pre-pandemic sera. Among unvaccinated children aged 1–4 and 5–17 years the prevalence of HI titers ($1:10) was 27.1% (95% CI: 23.5–31.3) and 53.5% (95% CI: 50.9–56.2) compared to 1.7% and 5.5%, respectively, for pre-pandemic sera, accounting for a serologically determined incidence of influenza A (H1N1) 2009 during the season 2009/2010 of 25,4% (95% CI : 19.3–30.5) in children aged 1–4 years and 48.0% (95% CI: 42.6–52.0) in 5–17 year old children. Of children with HI titers $1:10, 25.5% (95% CI: 22.5–28.8) reported no history of any infectious disease since June 2009. Among vaccinated children, 92% (95%-CI: 87.0–96.6) of the 5–17 year old but only 47.8% (95%-CI: 33.5– 66.5) of the 1–4 year old children exhibited HI titers against influenza A virus (H1N1) 2009. Conclusion: Serologically determined incidence of influenza A (H1N1) 2009 infections in children indicates high infection rates with older children (5–17 years) infected twice as often as younger children. In about a quarter of the children with HI titers after the season 2009/2010 subclinical infections must be assumed. Low HI titers in young children after vaccination with the AS03B-adjuvanted split virion vaccine need further scrutiny.

description: Background Cam and/or pincer morphologies (CPM) are potential precursors to hip osteoarthritis (OA) and important contributors to non-arthritic hip pain. However, only some CPM hips develop OA and/or pain, and it is not clear why. Anterior impingement between the femoral head/neck contour and acetabular rim during motion is a proposed pathomechanism. Understanding how activity and deformity combine to produce impingement may shed light on the causes of hip degeneration/pain. The objective of this study was to determine the accuracy of a subject-specific hip model driven by subject-specific motion data in predicting anterior impingement. Methods We recruited 22 participants with CPM (both with and without pain) and 11 controls. We collected subject-specific 3D kinematics during squatting and sitting flexion, adduction, and internal rotation (FADIR) (an active and a passive maneuver, respectively, proposed to provoke impingement). We then developed 3D subject-specific hip models from supine 3T hip MRI scans that predicted the beta angle (a measure of anterior femoroacetabular clearance) for each frame of acquired kinematics. To assess the accuracy of these predictions, we measured the beta angle directly in the final position of squatting and sitting FADIR using open MRI scans. We selected the frame of motion data matching the static imaged posture using the least-squares error in hip angles. Model accuracy for each subject was calculated as the absolute error between the open MRI measure of beta and the model prediction of beta at the matched time frame. To make the final model accuracy independent of goodness of match between open MRI position and motion data, a threshold was set for least-squares error in hip angles, and only participants that were below this threshold were considered in the final model accuracy calculation, yielding results from 10 participants for squatting and 7 participants for sitting FADIR. Results For squatting and sitting FADIR, we found an accuracy of 1.1°(0.8°) and 1.3°(mean (SD), and root mean squared error, respectively) and 0.5°(0.3°) and 0.6°, respectively. Conclusion This subject-specific hip model predicts anterior femoroacetabular clearance with an accuracy of about 1°, making it useful to predict anterior impingement during activities measured with motion analysis.
Challenges to a sharp change in $G$ as a solution to the Hubble tension

description: It has been proposed that the gravitational constant $G$ abruptly decreased around 130 Myr ago, making Type Ia supernovae (SNe) in the Hubble flow intrinsically brighter than those in host galaxies with Cepheid distances. This would make Hubble flow SNe more distant, causing redshifts to rise slower with distance, potentially solving the Hubble tension. We explore a wide range of unattractive consequences of this ``$G$ step model'' (GSM). We find that since the luminosities of Sun-like stars scale as approximately $G^{5.6}$, the Solar luminosity would have dropped substantially 130 Myr ago in this scenario, likely pushing Earth into a planetary glaciation. However, there was no Snowball Earth episode in the last 500 Myr. The GSM also implies that the length of a year would have abruptly increased by about 10%, but the number of days per year has evolved broadly continuously according to geochronometry and cyclostratigraphy. The GSM would considerably alter stellar evolution, causing the Sun to have exhausted about 2/3 of its fuel supply rather than 1/2. This would make the Sun's helioseismic age exceed that of the oldest meteorite samples, but these agree excellently in practice. The expected age of the Universe also agrees well with that of the oldest Galactic stars assuming constant $G$. The GSM however implies these stars are younger, creating a lack of stars from the first 3 Gyr of cosmic history. These arguments pose significant challenges to models seeking to resolve the Hubble tension through a transition in $G$.

description: We have investigated He+-ion bombardment on lattice-matched multi-layer InP/ In0.53Ga0.47As and In0.5Ga0.5P/ GaAs heterojunction bipolar transistor (HBT) structures. The bombardment of these structures was tested with a single energy implantation of helium-ions at 600 keV with a dose of 3x10 15 cm-2 at room temperature. Post implant annealing was performed for 60s from 50 to 575 o C. Maximum achievable sheet resistance of 3x10 7 W/sq was recorded for the GaAs-based base and collector layers of the InGaP/ GaAs HBT structure and 8x10 4 W/sq for the InGaAs-based collector layer of the InP/ InGaAs HBT structure. Comparison of annealing characteristics of bombarded GaAs- and InP- based HBT structures as a function of annealing temperature are reported here.
CELL DENSITY AS A POTENTIAL REGULATOR FOR TYPE VI SECRETION SYSTEM IN VIBRIO FISCHERI
Creators: name: Tyagi, Bhavyaa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: When bacteria colonize a system, they must compete for space and nutrients. During the competition process, some bacteria can build a contact-dependent molecular weapon that injects toxins inside competitor cells to eliminate them. One such molecular weapon is the Type VI Secretion System (T6SS), found in various bacteria colonizing marine hosts. Although this weapon can provide bacteria a competitive advantage during host colonization, we know little about the proteins that regulate the T6SS weapon in a host. We utilize the squid-vibrio symbiosis to understand how bacterial cells may regulate their T6SS weapon during host colonization. A previous random transposon screen identified additional genetic factors required to activate the T6SS in Vibrio fischeri. Two mutants with transposon insertions in genes not previously known to affect T6SS were isolated. These two mutants could not eliminate a competitor strain in coculture. To test whether the transposon insertion was preventing the T6SS activity, the transposon insertions were moved into a fresh wild-type background using natural transformation, and the remade mutants were tested for their killing activity. The remade mutants were still able to eliminate the target cells, and upon performing whole genome sequencing analysis, it was revealed that both original transposon mutants had a point mutation in the luxO gene. Previous work showed that LuxO is a quorum-sensing regulator active at low cell density, and a past transposon screen identified a similar mutation (luxO*) that locks the protein in a constitutively active state that mimics low cell density. To explore whether such a gain-of-function mutation in LuxO could regulate the T6SS, we overexpressed luxO* in a wild-type V. fischeri strain and co-incubated it with the target cell. The strains expressing the constitutively active luxO* allele could not eliminate the target strain for two out of four luxO* alleles tested, suggesting active LuxO could prevent T6SS-mediated killing. In instances where cells expressing the luxO* allele either eliminated the target or demonstrated reduced killing, there is a possibility that the wild-type copy of LuxO overrides the overexpressed luxO* allele in these cells. These findings lead us to infer that LuxO, active at low cell density or through a gain-of- function mutation (luxO*), may prevent T6SS activation. Our current research model suggests that LuxO may prevent expression of the T6SS weapon at low cell density, saving the cost of the unnecessary firing of the molecular weapon when contact with competitors is less likely.

description: PURPOSE: With improved cancer survival rates and the current trend of delaying parenthood, fertility is a growing issue among cancer patients. The purpose of this study was to evaluate the incidence of fertility counseling and sperm banking in reproductive-age male cancer patients and to assess factors that influence counseling and banking.
MATERIALS AND METHODS: Male patients ages 13 to 50 years who received a new cancer diagnosis from January 1, 2013, to May 1, 2015, and planned to initiate curative chemotherapy at our center were identified. Documentation of fertility counseling and sperm cryopreservation was abstracted from the medical record. Univariable and multivariable logistic regression modeling was used to examine variables associated with fertility counseling and sperm banking.
RESULTS: Of 201 patients who fit the study criteria, 59 (29%) received fertility counseling and 23 (11%) attempted sperm banking. All patients who banked sperm had documentation of fertility counseling. Younger patients were significantly more likely to be counseled, with mean ages of 27.4 and 40.4 years for counseled and noncounseled patients, respectively (P < .001). Among counseled patients, those with a lower median income (P = .038) or who had Medicaid or no insurance (P = .042) were less likely to bank sperm. In a multivariable logistic regression model, older age (5-year odds ratio, 0.61; P < .001) and presence of comorbidities (odds ratio, 0.15; P = .03) remained significantly associated with a lower counseling rate.
CONCLUSION: There is a low rate of fertility counseling and referral for sperm banking in young men with cancer receiving chemotherapy. Further work is needed to develop interventions to improve fertility counseling rates and opportunities for sperm banking.

description: One in 9 people $65 years of age in the
United States has Alzheimer’s disease
(AD), which is estimated to double by
2050 (1). This equates to about 4.4 million of the estimated
44 million people with AD worldwide in 2015
(1). In contrast, cardiovascular disease remains the
most common cause of morbidity and mortality
worldwide, with heart failure affecting an estimated
5.7 million U.S. adults (2,3). With the enormous toll
of heart failure, the impact of AD may not seem nearly
as daunting (2,3). Or is it?

description: Background The burden of readmissions after major cancer surgery is high. Prior work suggests that one-third of readmitted patients are readmitted to a different hospital than where the surgery was performed. The impact of this location of readmission needs to be more thoroughly understood. Methods This retrospective cohort study was performed on Surveillance, Epidemiology, and End Results (SEER)-Medicare patients with bladder, esophagus, lung, or pancreas cancer diagnosed from 2001 to 2007 who underwent extirpative surgery and were readmitted within 90 days. Readmission location was classified as ‘index’ if readmission was at the hospital where surgery was performed, or ‘different’ if readmission was elsewhere. Outcomes including complications, reoperations, in-hospital mortality, 90-day mortality, and 90-day total costs were compared based on the location of readmission using a propensity score inverse probability treatment weight analysis. Results Overall, 7903 (28 %) patients were readmitted within 90 days of index hospitalization. Thirty-three percent were readmitted to a different hospital (bladder 30 %, esophagus 34 %, lung 34 %, pancreas 34 %). Ninety-day mortality and total costs of care were not significantly different between the readmission location groups (all p > 0.05); however, substantial differences in the types of patients, and timing of and reasons for readmission were observed between the two groups. Conclusions Patients readmitted to different hospitals after major cancer surgery are a different group of patients than those readmitted to the index hospital. Accounting for this, we did not find significant differences in short-term clinical outcomes or costs of care based on readmission location; however, differences in long-term outcomes were observed that should be further explored in future studies.

description: The 2020 global outbreak of COVID-19 exposed and heightened threats to mental health across societies. Research has indicated that individuals with chronic physical health conditions are at high risk for suffering from severe COVID-19 illness and from the adverse consequences of public health responses to COVID-19, such as social isolation. This paper reports on the findings of a rapid realist review conducted alongside a scoping review to explore contextual factors and underlying mechanisms or drivers associated with effective mental health interventions within and across macro–meso–micro systems levels for individuals with chronic physical health conditions. This rapid realist review extracted 14 qualified studies across 11 countries and identified four key mechanisms from COVID-19 literature—trust, social connectedness, accountability, and resilience. These mechanisms are discussed in relation to contextual factors and outcomes reported in the COVID literature. Realist reviews include iterative searches to refine their program theories and context–mechanism–outcome explanations. A purposive search of pre-COVID realist reviews on the study topic was undertaken, looking for evidence of the robustness of these mechanisms. There were differences in some of the pre-COVID mechanisms due to contextual factors. Importantly, an additional mechanism—power-sharing—was highlighted in the pre-COVID literature, but absent in the COVID literature. Pre-existing realist reviews were used to identify potential substantive theories and models associated with key mechanisms. Based on the overall findings, implications are provided for mental health promotion policy, practice, and research.

description: Enhanced recovery after surgery (ERAS) protocols have proven effective in a variety of surgical specialties. Published reports on these pathways within cardiac surgery and interventional cardiology are limited. Invasive aortic valve replacement procedures are increasingly being performed by hybrid groups of interventional cardiologists and surgeons through transcatheter aortic valve implantation (TAVI). The TAVI patient population is at a higher surgical risk compared with those undergoing surgical aortic valve replacement since they are older, frailer, and have significant co-morbidities which result in an increased risk of perioperative complications. ERAS protocols have the potential to help these patients undergoing TAVI procedures. In conclusion, we propose a TAVI ERAS protocol with a call-to-action for other centers to implement an ERAS protocol to improve hospital and cardiac outcomes.

description:  Plants lack 7-transmembrane, G-protein coupled receptors (GPCRs) because the G alpha subunit of the heterotrimeric G protein complex is “self-activating”—meaning that it spontaneously exchanges bound GDP for GTP without the need of a GPCR. In lieu of GPCRs, most plants have a seven transmembrane receptor-like regulator of G-protein signaling (RGS) protein, a component of the complex that keeps G-protein signaling in its non-activated state. The addition of glucose physically uncouples AtRGS1 from the complex through specific endocytosis leaving the activated G protein at the plasma membrane. The complement of proteins in the AtRGS1/G-protein complex over time from glucose-induced endocytosis was profiled by immunoprecipitation coupled to mass spectrometry (IP-MS). A total of 119 proteins in the AtRGS1 complex were identified. Several known interactors of the complex were identified, thus validating the approach, but the vast majority (93/119) were not known previously. AtRGS1 protein interactions were dynamically modulated by d-glucose. At low glucose levels, the AtRGS1 complex is comprised of proteins involved in transport, stress and metabolism. After glucose application, the AtRGS1 complex rapidly sheds many of these proteins and recruits other proteins involved in vesicular trafficking and signal transduction. The profile of the AtRGS1 components answers several questions about the type of coat protein and vesicular trafficking GTPases used in AtRGS1 endocytosis and the function of endocytic AtRGS1.

description: Bridging the literatures on entrepreneurship and the aging workforce, we study the factors, particularly job loss, wealth, education, and risk aversion, associated with entry into self-employment at older ages using a multinomial logit hazard model. Using the Health and Retirement Study, we disaggregate self-employment by defining four types through an interaction along two scopes: one that divides along those with supervisory responsibilities or business asset ownership and the other divided into so-called “knowledge” and “non-knowledge” occupations. We find that job loss shows a strong association with entry into self-employment, particularly with less desirable forms of self-employment. In addition, we show that there are large differences between individuals in these alternative measures of self-employment and that there are distinctive factors that influence entry into these types. Additionally, we show that there are some differences in the factors affecting men’s and women’s entry into self-employment.

description: This study explores how 3 Latino male college students who attended rural, K–12 North Carolina schools use their conceptions of home to fight against oppressive forces in the southern United States. Specifically, through the use of life history data, I unpack both the challenges that they face and the agency-laden decisions that they make to navigate various tensions related to their Latin@ identities. This work extends current literature on men of color in schools, which largely omits the experiences of Latino male students that come of age in rural, southeastern, US settings.
