Non-dominant Groups Research Articles

A Multi-institutional Cluster Analysis to Identify Groups of Courses with Exemplary Opportunity Gaps for Undergraduate Students in the Biological Sciences.

Examining institutional data from seven cohorts of students intending to major in biology across five research-intensive institutions, this work analyzes opportunity gaps-defined as the difference between the grade received by students from the dominant and nondominant sociodemographic groups in institutions of higher education-at the course-section level across mathematics, physics, biology, and chemistry disciplines. From this analysis, we find that the majority of course sections have large opportunity gaps between female and male students, students who are Black, Latino/a/e/x, or indigenous to the United States and its territories and students who are White or Asian, first-generation and non-first-generation students, and low-income and non-low-income students. This work provides a framework to analyze equity across institutions using robust methodology, including: using multiple approaches to measure grades, quantile regression rankscores which adjust for previous academic performance, and cluster analysis. Recommendations are provided for institutions to identify faculty who have equitable course sections, automate equity analyses, and compare results to other institutions to make a change toward more equitable outcomes.

Pokłosie powstania 1863–1864 r.: nieortodoksyjna refleksja

Today, in Lithuanian, Polish, Belarusian and even Ukrainian society, the January Uprising has become a symbol of the ‚ fight for freedom’. This article attempts to answer the question: did/do Polish, Lithuanian, Belarusian and Jewish societies really have anything to glorify? In other words, from the perspective of nineteenth and early twentieth century nationalisms (and therefore not from an academic perspective), was the uprising in any way useful to them? Or to put it another way, did it do more good or harm? For all non-dominant ethnic groups, the uprising brought new repression and discrimination (although sometimes discrimination against one group objectively benefited another group), and with the exception of the Poles, it is difficult to see the impact of this historical event as a positive image in the process of nationalising the masses until World War One. The fact that such an image was created later is simply an‚ invented tradition’. The fact that a positive image of the uprising was ‚invented’ later in Lithuanian or Belarusian societies does not mean that it did not (or does not now) influence the mobilisation of the masses, but it is not a direct consequence of the uprising, but a narrative constructed by later generations.

A Cross Community Comparison of Muting in Conversations of Gendered Violence on Reddit

Gender-based violence (GBV) is an ongoing public health issue. Prevention practice and research on GBV contend with an incomplete understanding of its public health burden due to gender-exclusive definitions of GBV and inhibited survivor disclosure. Prior work in CSCW and HCI has explored sensitive disclosures and GBV conversations but excludes examination of conversation dynamics in surfacing knowledge of GBV. We used a mixed-methods approach to understand the phenomenon characterized by Muted Group Theory as a mechanism inhibiting disclosure in the context of GBV discussions on Reddit. Using an iterative process informed by literature of GBV research on cis-gender women, girls, trans, and non-binary populations, we developed comprehensive keywords to obtain, annotate, and analyze 298 posts and 10,369 comments about GBV across 7 subreddits. We found that muting faced by survivors offline, precluding reporting, is replicated on the Reddit platform. This study surfaced 5 categories of muting in discussions of GBV situated by variations in communication norms between dominant and non-dominant groups. These findings were supported by analysis of linguistic attributes that inform an Ensemble Classifier's detection of muting in conversations of GBV. The results offer that muting is a harmful occurrence in online disclosures of GBV that is mediated by existing moderation practices. This work contributes an expanded understanding of GBV conversations online, muting as a feature of those conversations, and an initial foray into detection to inform muting prevention.

Does hand dominance influence clinical outcomes and implant survival in shoulder arthroplasty?

BackgroundTotal shoulder arthroplasty (TSA) is a successful treatment method for patients with end-stage glenohumeral osteoarthritis and different factors influencing the clinical outcome have been determined. However, the role of hand dominance on the postoperative clinical results and implant survival is not well analyzed. Hypothesis: Hand Dominance does not influence the outcome after TSA. Patients and methodsIn this single center cohort study, 138 consecutive patients with primary Osteoarthritis (OA)were treated with a TSA and evaluated with a mean follow-up of 45 months (range 24–158 months). 62.32 % (86 patients) underwent TSA on the dominant side (DOM group) and 37.68 % (52 patients) on their non-dominant side (NON-DOM group). For clinical evaluation the adjusted Constant-Murley (CS) score, pain (Numeric analog scale (NAS)), subjective satisfaction and range of motion (ROM) were recorded. Furthermore, survivorship analysis was performed for the endpoint revision for any reason. ResultsBoth dominant (DOM) and non-dominant (NON-DOM) groups demonstrated significant improvement in all clinical outcomes from pre-to postoperative (p < 0.0001) with no between-group differences (p > 0.05). Implant survival was 98.8 % at 123 months (DOM) and 90 % at 158 months (NON-DOM) (p = 0.89). ConclusionHand dominance did not influence postoperative outcomes, survivorship, or age at time of surgery. Patients can expect excellent results after TSA regardless of their predominant dexterity. Level of evidenceRetrospective cohort study, Level III.

Catheter-related thrombosis in adults with cancer: a secondary analysis of a prospective randomized controlled trial

BackgroundCatheter-related thrombosis (CRT) is a complication of central venous access devices (CVADs). Evidence is variable regarding the significance of the side of catheter insertion. The role of the patient’s hand dominance in predisposition to CRT remains uncertain. ObjectivesIn a prospective randomized controlled trial, adult cancer patients were randomly allocated to either dominant or nondominant side CVAD insertion. The primary endpoint of this trial examined the incidence of catheter-associated bloodstream infection. Here, we report the secondary endpoint of the incidence of CRT. MethodsSix hundred forty CVADs were randomized to the dominant (n = 322) or nondominant (n = 318) side of insertion. Only symptomatic patients underwent ultrasound imaging to evaluate for CRT. ResultsThe median patient age was 58 years, 60% of patients had hematologic malignancies and 40% had solid tumors. CVADs used were peripherally-inserted central catheter line (67%), tunneled CVAD (23%), or nontunneled CVAD (10%). The CRT incidence rate was 0.65 versus 0.82 per 1000 line days in the dominant versus nondominant group (hazard ratio [HR], 1.2; 95% CI, 0.58-2.48; P = .63). There was no significant difference in CRT incidence rate between left- and right-sided insertions (HR, 0.63; 95% CI, 0.30-1.32; P = .22). The CRT incidence rate was lower in right-handed versus left-handed line inserters (HR, 0.29; 95% CI, 0.12-0.71; P = .007). ConclusionThe rate of CRT was not associated with whether CVAD insertion was on the patient’s dominant or nondominant side or the side of insertion. The role of inserter hand dominance requires further investigation.

Association of lifelong exercise characteristics with aortic pathology in patients with Marfan syndrome

Abstract Background Marfan syndrome (MFS) is a genetic connective tissue disease with an increased risk for aortic root dilatation and aortic dissection. Current guidelines, based on expert consensus, recommend exercise restrictions due to concerns that exercise-induced hemodynamic stress may accelerate aortopathy. Studies examining exercise characteristics and their association with aortopathy in MFS patients are lacking. Purpose To assess the association of lifelong exercise characteristics (volume, intensity and type) with the presence of aortic dilatation in MFS patients. Methods An international multi-centre study was conducted in MFS adults. Patients were classified as sedentary (&amp;lt;500 metabolic equivalent of task minutes per week [MET-min/wk]), active (500-1000 MET-min/wk), or highly active (≥1000 MET-min/wk) based on lifelong exercise volumes assessed by a validated questionnaire. Patient’s dominant exercise intensity was classified as moderate (3-6 MET) or vigorous (≥6 MET), and sport type as skill, power, mixed, or endurance. Echocardiography was used to assess diameters at the sinuses of Valsalva (SoV) and ascending aorta (AA), and Campens Z-scores were calculated. Aortic dilatation was evaluated as a diameter ≥40, ≥45 mm, a Z-score ≥2 or ≥3 respectively. Results 315 patients (36[27-49] years, 53% male) were included of which 104 were sedentary, 77 active and 134 highly active (Fig. 1). 42 patients did not perform sport-related exercise, whereas 147 and 121 patients predominantly participated in moderate or vigorous intensity sports. Patients performing sports were allocated to the skill (n=13), power (n=27), mixed (n=158), endurance (n=66) or non-dominant (n=9) exercise type group. Mean SoV and AA diameters were 42.9±7.7 mm and 33.9±7.3 mm. SoV or AA diameters of ≥40 mm were present in 200 (64%) and 41 (13%) patients, whereas 223 (71%) and 81 (26%) patients had a Z-score ≥2 for the SoV or AA. Exercise volume was not associated with SoV dilatation (Fig. 2). Moderate and vigorous intensity sports were associated with a lower prevalence of SoV Z-score ≥3. Power sport was associated with a lower prevalence of all definitions of SoV dilatation, whereas mixed and endurance sports were associated with a lower prevalence of SoV Z-score ≥3. No associations were found with AA dilatation. Of the 17 (5%) patients who suffered from an aortic dissection, 1 case occurred during walking (type A dissection) whereas all other cases were not exercise-related. Conclusions Lifelong exercise volumes were not associated with aortic dilatation in MFS patients. Power sports and vigorous intensity exercise were inversely related to SoV dilatation. Further investigation is warranted to clarify whether this association reflects that patients engaging in these activities have a less severe cardiovascular phenotype, or that they are protected from exercise-related aortic complications, and if patients may miss health benefits due to too exercise restrictions.

The End of the Ottoman Empire: A Century after the Fall

A century ago, the Ottoman Empire finally ceased to be after a long reign that stretched back to the late medieval period, and, ostensibly, nobody really missed it. It was once possible to write about the fall of the Ottoman Empire as the overdue culmination of a process that gave rise to independent nation–states. But, increasingly, the empire casts a long shadow on the historiography of the Middle East, and its last days emerge among its most consequential for the future of the region. The same political actors who reshaped late Ottoman politics were integral to the struggle for the post-Ottoman landscape. These individuals included provincial elites from nondominant ethnic groups who, rather than embracing ethnic nationalism, remained Ottomanist in their vision of the region's future until the final moment. Newer scholarship rejects the teleology of the nations that emerged from postwar fracturing, demonstrating that the map was not redrawn by the victors in an instant. It was forged, instead, through armed struggles against European imperial powers and among rival movements that lasted for years. One hundred years after the Ottoman Empire's collapse, historians are still excavating its long-ignored relevance for understanding the modern Middle East, which was buried under the weight of nationalist and Orientalist metanarratives that never questioned the inevitability of its demise.

Differences in Somatosensory Function Related to Hand Dominance: Results of a Quantitative Sensory Testing Study in Healthy Volunteers.

Quantitative sensory testing commonly utilizes the unaffected, contralateral side as a control to detect somatosensory dysfunction. There is scant evidence that somatosensory function for the volar dominant and non-dominant hands is equivalent, therefore intra-patient comparisons are unwarranted. This study aimed to identify dominance-related differences in palmar hand somatosensation, thereby determining if the unaffected contralateral hand is a valid comparator in clinical populations. With ethical approval (IREC_13_1_10) and informed consent, 110 healthy adult volunteers' participated in this clinical measurement study. Somatosensory function was assessed with the German Research Network on Neuropathic Pain (DFNS) quantitative sensory testing (QST) protocol. Half of the participants were tested on the dominant hand. Thirteen parameters of thermal and mechanical detection and pain threshold were evaluated at both the dorsal and volar hand (distal middle finger). Tests were performed in the same order and instructions were read from a standardized script. Results for dorsal hand tests were compared to DFNS normative data to confirm participants met study inclusion criteria. Between-group differences for age and sex were investigated with the independent samples t-test and Chi-square test of independence, respectively. Group differences for dominant and non-dominant hands for all 13 continuous QST parameters were investigated with the Mann-Whitney U-test. Data for 106 participants were included in statistical analysis. Fifty percent of participants were tested on the dominant hand [n=53]; there were no differences for age or sex between groups (dominant or non-dominant hand test group). The dominant volar hand was significantly more sensitive to vibration detection threshold than the non-dominant hand (P=0.001). There were no significant differences related to dominance for other DFNS QST measures. For quantitative sensory testing with the DFNS protocol in healthy cohorts, the contralateral, unaffected hand is a valid control, with the exception of vibration detection threshold.

Prevalence and Risk Factors of Headache Associated with COVID-19.

Background: Headache is a prevalent and disabling non-respiratory symptom of COVID-19, posing a persistent challenge in post-COVID syndrome. This study aimed to determine the prevalence, phenotypes, risk factors and biomarkers associated with COVID-related headaches. Methods: A retrospective analysis of 634 hospitalized COVID-19 patients was conducted, with 295 participants being followed up 12-15 months post-discharge via telephone call. Initial laboratory workups, including complete blood count and various biochemical parameters, were compared between headache and non-headache groups. Results: One-third of hospitalized patients experienced headaches, predominantly younger individuals (p < 0.001) and women (p = 0.002). Non-dominant headaches were characterized as dull (56.9%) and holocranial (26.5%), while dominant headaches were unilateral (31.3%) with photophobia (34.3%) and nausea (56.3%). Persistent headaches were unilateral (40%) and pulsating (38%) with phonophobia (74%). Decreased CD4 T cells independently predicted COVID-associated headaches, with elevated IL-6 levels noted in the dominant-headache group (p = 0.040). Remarkably, 50% of patients reported persistent headaches 12-15 months post-infection. Dexamethasone administration significantly reduced the likelihood of long-COVID headaches (52% vs. 73%, p = 0.029). Conclusions: Headache was present in one-third of patients with heterogenous phenotypes: tension headache in the non-dominant group, and migraine in the dominant and persistent headache groups. Persistent headache remains a challenge, with dexamethasone showing potential in reducing its incidence, emphasizing the need for tailored approaches in managing long-COVID headaches.

Kauno gubernatorius Piotras Veriovkinas ir lietuvių švietimo draugija „Saulė“

The article aims to explains why, among all the non-dominant ethnic groups, the imperial authorities in the so-called Western region allowed the existence of only the Lithuanian educational society ‘Saulė’ [The Sun]. The argument is made that this was due to the recognition of Kaunas governorate as a Lithuanian ‘national territory’ on the Russian mental map, the lack of assimilation potential (from the point of view of the officials), the admission that the Lithuanians were ethnically-culturally detached from the ethnic Russians, as well as the efforts of the governor of Kaunas, Piotr Verevkin, to prevent the closure of this society. Part of the article is devoted to a discussion of Verevkin’s motives.

Internalized Oppression: Exploring the Nuanced Experiences of Gender and Sexuality in Historically Black Colleges and Universities

In the American South at the turn of the twentieth century, quality education was scarce and legislative laws were put in place to ensure that African American individuals remained far away from Predominantly White Institutions (PWIs). As a result, Historically Black Colleges and Universities (HBCUs) became a catalyst for change in this “separate but equal” society. This article will explore the significance of HBCUs in elevating Black Americans throughout the twentieth century, while also assessing the conservative nature of the institutions and their inflexibility towards the various nuances of African American communities. While it is not particular to HBCUs, a tolerance of toxic masculinity and severe conservatism has resulted in starkly different Black experiences for cis-gendered heterosexual men, in contrast to cisgendered women and other members of the 2SLGBTQI+ community. By investigating various experiences within HBCUs, this article will explain the unifying and uplifting benefits for Black individuals in these institutions, as well as its many divisive components. My research will strive to analyze and properly convey the various nuanced experiences throughout HBCUs and assess the variety of factors that have led to these underrepresented interactions. This article will provide an understanding of how HBCUs have and continue to reflect American society but also demonstrate their role in various Black communities and their representation of non-dominant Black groups from the late nineteenth century to the present.

Mixed Couples, Mixed Attitudes: How Interracial Couples in Marketing Appeals Influence Brand Outcomes

Abstract Interracial couples are increasingly featured in marketing messages, yet little is known about how their representation influences consumer behavior. Across six experiments (N = 4,956) and a field study on Facebook, interracial couples in marketing appeals enhance brand outcomes relative to monoracial dominant (i.e., White) couples, but decrease brand outcomes relative to monoracial nondominant (i.e., minority) couples. These effects stem from how the racial composition of dominant (vs. nondominant) members within a couple either amplifies or dilutes perceived warmth. Monoracial couples possess consistent stereotype attributes, with dominant (vs. nondominant) groups typically seen as lower in warmth. Thus, monoracial couple warmth is amplified: monoracial dominant couples are seen as less warm (i.e., negative amplification), and monoracial nondominant couples as warmer (i.e., positive amplification) than the individuals in the couple. Interracial couples possess inconsistent racial attributes, inducing stereotype dilution with intermediate levels of perceived warmth. Warmth drives brand outcomes above and beyond brand diversity, social desirability, and brand morality. Effects are moderated by consumers’ social dominance orientation and whether the monoracial dominant couple is nondominant along another dimension (i.e., sexual orientation). This work holds theoretical implications for stereotyping research and provides practical insight into multiracial marketing.

Latina mothers in participatory action research: Insights and reflections of a mathematics co-design session tool

Co-design methods offer a powerful collaborative approach that allows for integrating various participants’ needs and expectations in the design process. However, current co-design tools often reflect a Eurocentric bias, limiting their utility in diverse settings. This article explores co-design methodologies and their application in a study with Spanish-speaking Latina mothers living in Southern California. I focus on co-design tools and processes, integrating culturally sustaining methods that respect and value the lived experiences of Latina mothers. Drawing from a qualitative phenomenological research approach and using in-depth interviews, the study underscores the mothers’ ways of knowing, highlighting personal math experiences and traditions in co-design sessions where the mothers sought to develop a math activity for their children. The article contributes to the literature on co-design methodologies to include culturally inclusive research tools and practices, emphasizing a co-design process that works “with” rather than “for” nondominant social groups.

Performance Differences in Elite National Basketball Association and Women's National Basketball Association Players Based Upon Whether the Dominant or Non-dominant Achilles Tendon Was Ruptured.

Background National Basketball Association (NBA) and Women's National Basketball Association (WNBA) players with Achilles tendon ruptures have previously been noted to have a significant decline in performance post-injury. There has been recent anecdotal evidence that elite players with dominant Achilles tendon ruptures may be able to return at a higher level of play post-rupture. Objective This study aimed to evaluate for any differences in performance in higher-performing NBA and WNBA players with dominant versus non-dominant Achilles tendon ruptures pre- and post-injury. Methods This study was conducted at the University of Pennsylvania, Department of Physical Medicine and Rehabilitation. NBA and WNBA players with an Achilles tendon rupture from 1990 to 2020 were identified. Only elite players, indicated by an average player efficiency rating (PER) of >15 in either of the three seasons pre/post-injury, were included. The average PER, offensive rating, defensive rating, and usage percentage were compared in the three seasons pre- and post-injury. Results Eighteen players met the inclusion criteria, and nine each were classified as dominant and non-dominant Achilles tendon ruptures based on their primary shooting hand. There was no significant difference between the dominant and non-dominant rupture groups in any outcomes pre-injury, including age. The non-dominant cohort had a significant decline in PER (20.04 vs. 14.16; p < 0.001) and offensive rating (110.33 vs. 101.56; p = 0.004) post-injury. There was no significant difference observed post-injury in defensive rating or usage percentage. The dominant cohort had no significant difference in any outcomes post-injury, returning to the same level of play as pre-injury. Despite no difference existing between the groups at baseline, the dominant group performed significantly better post-rupture with regardto PER (19.56 vs. 14.16; p < 0.001) and offensive rating (114.00 vs. 101.56; p < 0.001) versus the non-dominant group. Conclusion Elite NBA and WNBA players with dominant Achilles tendon ruptures had no change in performance post-injury, returning to the same level of production as pre-injury. Post-rupture, they demonstrated notably superior outcomes versus the non-dominant group with regardto PER and offensive rating. The non-dominant rupture group experienced the same decline in PER and offensive rating post-injury observed in previous studies. The data indicatethat elite NBA and WNBA players with a dominant Achilles tendon rupture have a much more favorable recovery post-injury and are able to return to thesame level of performance.

Criminal Behaviors Among Minorities: A Social Resistance Perspective

The social resistance framework offers an explanation for high-risk and criminal behaviors among non-dominant minority groups. The study explores the generalizability of the framework to minority groups which are marginalized for different reasons, such as immigration, and deep historical national conflicts, and across several criminal behaviors, by surveying a representative sample of more than 1,000 participants from Israel's majority population and four minority groups—Muslims, Jews of Ethiopian origin, immigrants from the former Soviet Union, and ultra-Orthodox Jews. Negative binomial regressions show that social resistance is positively associated with criminal behaviors, controlling for exposure, demographic characteristics, and previous explanations. Additionally, both levels of social resistance and its association with criminal behaviors vary between the different non-dominant minority groups. The study supports the premises of the framework, showing that social resistance plays a role in criminal behaviors among minority groups which are marginalized for different historical reasons.

Acting as if: the utopian political thought and actions of the US disability rights movement

This article studies the response of the US disability community to the prevalent assumption that disabled people do not have a future, in the form of the disability rights movement. It provides an exploratory discussion of the key role played by utopianism in the response. In doing so, the article adds to critical theorizing on the importance of utopia to the oppression of non-dominant groups and to transcending that oppression. I use utopian studies scholarship to interpret the activities leading up to the passing of the Americans with Disabilities Act in 1990 as a minor utopia, characterized by an ambiguous, grounded, and provisional effort to imagine alternative ways of being. I articulate the central role played by a positive vision of disability and disabled people for this inversion of the historically negative relationship between utopia and disability. The article turns to disability activists to show that the movement countered exclusionary utopian approaches by acting as if it had a right to envision and enact a different, better future for all from the perspective of disability and disabled people.

Customer Inferences about Racial Composition in Ads: A Comparison of Monoracial and Interracial Models

Across four experiments, we use correspondent inference theory to explain customer inferences about organizational inclusiveness and ulterior motive following exposure to monoracial (same race) or interracial (different race) advertising models. The results reveal that the presence of monoracial models from a nondominant racial group (Black; Latino/a/x) or interracial models improves perceptions of organizational inclusiveness more than monoracial models from a dominant racial group (White). However, the presence of interracial models also heightens consumers’ suspicion of the advertiser’s ulterior motive, thereby negatively impacting brand evaluations. We eliminate alternative explanations and identify a theoretically and practically relevant boundary condition that contextualizes the general findings: featuring a larger number of models reduces consumers’ suspicion and improves evaluations of interracial models in advertisements. We empirically confirm that the models’ racial composition impacts perceptions of organizational inclusiveness, ulterior motive, attitudes toward the ad, and purchase likelihood. We discuss the contributions, implications, and limitations of the research.

Why Triptych? Promoting Student Engagement with Counternarratives via Genre Blending

A new subtype of multigenre paper helps students in both dominant and nondominant groups to connect with counternarratives.

Comparison of dominant- and non-dominant-hand cateract surgery outcomes by a single surgeon

PurposeTo compare dominant and non-dominant hand phacoemulsification surgery outcomes. MethodsThis retrospective, single-center study included 300 patients who underwent phacoemulsification surgery by a single, right-handed surgeon. The patients were divided into two groups according to whether the surgeon used his dominant or non-dominant hand during surgery. Right eye operations were performed with the right hand, and left eye operations were performed with the left hand. Detailed ophthalmological examinations were performed on all patients preoperatively and postoperatively. Intraoperative phacoemulsification parameters, the presence of intraoperative and postoperative complications, postoperative refractive errors, visual acuity, and surgically induced astigmatism values were compared between the groups. ResultsThere were 171 patients in the dominant hand phacoemulsification group and 129 patients in the non-dominant hand phacoemulsification group. The distributions of age, gender, systemic diseases, and lens opacification were similar between the groups (p>0.05, for all). No statistically significant difference was observed between the two groups in terms of total operation time, phaco power, ellips fx, or ultrasonic time (p>0.05, for all). There was also no significant difference in relation to intraoperative and postoperative complication distributions, postoperative third-month refractive errors, visual acuity, or surgically induced astigmatism values (p>0.05, for all). ConclusionThis study demonstrated that cataract surgery performed by a single surgeon can be effectively and safely performed using both hands on patients in a real operating theater environment. More objective results can be obtained with surgeries performed by a larger number of experienced surgeons.
