Survey on the Impact of Historical Museum Exhibition Forms on Visitors’ Perceptions Based on Eye-Tracking

Exhibition design in museum space is of great significance in enhancing cultural attraction, visitor experience, and heritage conservation. With the growth of spiritual and cultural needs, the construction of museums has increased, but the quality of exhibitions has been improved to a limited extent. In order to explore visitors’ perceptual experience in terms of display forms, this paper combines eye-tracking technology and subjective evaluation to select three display forms, namely, stand-alone display form, combined picture and object form, and combined 3D object and physical form, for the research. Combining field research, eye-tracking experiments, and subjective questionnaire evaluations, this study explores the relationship between visual perception and emotional experience in different display formats. The results showed that (1) the effects of different display formats differed between visual perception and emotional experience, and (2) there is some correlation between visual perception and emotional experience. Specifically, the number of fixations sessions was negatively correlated with fun, richness, comfort, and attractiveness and positively correlated with authenticity, while the average fixation time was positively correlated with the former and negatively correlated with authenticity. Combining the two dimensions, the study concluded that visitors’ experience satisfaction and preference are high in response to the form combining 3D objects and physical objects; the exhibition form of combining pictures and physical objects produces a higher degree of cognition in a short period of time; and the stand-alone display form has the lowest degree of preference, with poor information retention among visitors. It is hoped that this study will provide some reference for the use of exhibition forms in historical museums.

An Experimental Study of Virtual Space Design for Emotional Intervention in Autistic Children with Eye Movement Technology

In this thesis, virtual technology is combined to study the eye-tracking status of children with Autism Spectrum Disorder (ASD) towards their preference for space. Aided by virtual technology, experimental research is conducted to capture the Eye-tracking data of the subjects, so as to determine their degree of preference for space. A one-week experiment of virtual space preference is performed on ten children with ASD aged 8-14, and the experimental data are collected and organized by the researcher from two parts, namely, eye-tracking data validity and spatial validity. By comparing the experimental data processing, it is figured out that the subjects are more inclined to Space 2 in the experiment, and most of the subjects show a strong interest in Space 2. These results preliminarily indicate that eye-tracking data of children with ASD can serve as a basis for judging their preferences.

Determining the thermal comfort of naturally ventilated state colleges located in Madhya Pradesh, India

ABSTRACT Through the establishment of optimal thermal conditions, educational institutions can develop an environment favourable to learning, concentration, and academic achievements. Additionally, comfortable temperatures can contribute to the overall well-being and satisfaction of both students and teachers, fostering a positive educational experience. In this study, we aimed to determine the impacts of environmental factors on students’ thermal comfort in three state colleges of Madhya Pradesh. A total of 784 students participated in a questionnaire study conducted during May (Summer season), August (Monsoon season), October (Autumn season), and December (Winter season) of 2023 to assess occupants’ degree of clothing, temperature preference, and metabolic rates. Indoor and outdoor temperatures, relative humidity, and air velocity were measured using an anemometer. Throughout the study period, the thermal comfort range was determined to be between 21.5°C and 28.5°C, with 25°C as the neutral temperature. It has been noted that the clothing pattern varies during the year (0.47-0.85 Clo). Additionally, implementation of the adaptation strategies, such as switching on and off fans or opening windows, helped lessen discomfort in the classroom. The findings indicate that, in contrast to the other seasons, the summers brought exceptionally high levels of heat discomfort to the occupants.

Gender differences in adolescent food preferences and their association with parent food preferences: data from the China Health and Nutrition Survey (CHNS).

Food preference is an important factor that affects one's eating behavior and dietary intake. Parent food preferences and food choices may influence children food preferences. This study is aimed to describe gender differences and time trends of Chinese adolescent food preferences and to explore the association between adolescent and their parent food preferences. The data were drawn from four waves of the China Health and Nutrition Survey (CHNS) conducted between 2006 and 2015. Participants were asked to indicate their degree of preferences for five food categories (fast food, salty snack food, fruits, vegetables, and soft/sugary drinks) using a 5-point Likert scale (from "dislike very much" to "like very much"). Logistic regression was performed to determine the association of food preferences between adolescents and their parents. Adolescent preferences for unhealthy foods were significantly higher than those of adults. Adolescent food preferences for fruits and vegetables decreased slightly over nine years, and there were gender differences in healthy food preferences (girls > boys, P < 0.05). Regardless of boys or girls, adolescent food preferences for healthy foods (fruits and vegetables) were significantly associated with both their fathers (OR: 3.64-4.58 for boys and 2.71-4.39 for girls) and mothers (OR: 2.13-4.11 for boys and 3.07-5.66 for girls) food preferences. For fast food and salty snack food preferences, boys appeared to be influenced greater by their fathers than girls, while girls appeared to be influenced greater by their mothers than boys. The present study reveals a high degree of unhealthy food preferences among Chinese adolescents and a gender-specific association of fast food and salty snack preference between Chinese adolescents and their parents. Our results may be useful for interventions to reduce adolescent unhealthy food preferences and intakes.

DEVELOPMENT OF METHODOLOGY AND STUDY OF THE INFLUENCE OF TECHNICAL, ORGANIZATIONAL AND TECHNOLOGICAL FACTORS ON THE DURATION OF THE PROCESS OF LIQUIDATION AND LOCALIZATION OF THE DEVELOPMENT OF DESTRUCTIONS

Analysis of the influence of technical, organizational and technological factors on the duration of the process of liquidation and localization of the development of destruction is an important stage of research into the process of liquidation of the consequences of accidental destruction. In order to compare options for liquidation and localization of the development of destruction of an emergency building, three options for reinforcement systems were analyzed: metal typical, wooden individual and combined. The work uses the method of analysis of hierarchies - a mathematical tool of a systematic approach to complex decision-making problems. The method does not impose the "correct" option, but allows you to interactively find an alternative (rational reinforcement option) that best matches the requirements for solving optimization tasks. To reduce the subjectivity of making a justified optimization decision in the conditions of complex multi-criteria optimization problems, a solution to the local problem of finding the optimal alternative according to the duration criterion, or a group of alternatives, taking into account the ratio of advantages based on the vector criterion, is proposed. To indicate the influence of advantages in quantitative expression, a pairwise comparison scale was used, which consists in a qualitative and quantitative assessment of relative advantage: equal in importance - 1; weak advantage – 2; average degree of preference ‒ 3; preference above the average degree ‒ 4; moderately stronger advantage ‒ 5; strong advantage ‒ 6; much stronger advantage ‒ 7; the most significant advantage is 8; absolute advantage ‒ 9. Initial data for choosing a temporary reinforcement option were obtained by comparing the estimated duration of dismantling and restoration works and optimizing the sequence of their execution for three options using wooden individual, metal typical and combined temporary reinforcement systems. It was established that it is impossible to ensure complete unification of reinforcement elements using only typical elements, therefore it is effective to use combined reinforcement systems using typical metal and individual wooden elements.

Operational Decisions of Construction and Demolition Waste Recycling Supply Chain Members under Altruistic Preferences

How to efficiently and greenly dismantle abandoned buildings and reuse them is a dilemma facing the building material industry’s low-carbon objective. However, relevant studies ignore the influence mechanism of altruistic preferences of enterprises on green dismantling technology in supply chains. Driven by filling this theoretical gap, this paper firstly integrates reciprocal altruism theory and the Stackalberg game method and constructs a construction and demolition waste (CDW) recycling supply chain system consisting of a recycler and a remanufacturer, in which enterprises’ altruistic preferences are considered. The main theoretical outcomes of this paper are as follows. (1) In the case of unilateral altruism, enterprises’ altruistic preference behaviors help in increasing the green dismantling technological level and the amount of CDW recycling. Under the mutual altruism model, the influence of the recycler’s altruistic preference degree on the amount of CDW recycled hinges on the remanufacturer’s altruistic preference degree. (2) The utility of the enterprises and the green dismantling technological level are optimized under the mutual altruism model. (3) In a system of unequal power, unilateral “goodwill” by the follower will have a negative effect on their own interests; the leader plays a crucial role in facilitating equal cooperation and realizing win–win situations. This paper enriches the reciprocal altruism theory in waste management. It also helps in providing guidance for the recycler and remanufacturer in making operational decisions.

Topical Formulations of Butterfly Pea Flower (Clitoria ternatea L.) Ethanol Extract by Ultrasound-assisted Extraction: Formulation and Antioxidant Activity Evaluation

The antioxidant action of Butterfly pea flower (Clitoria ternatea L.) is believed to be attributed to its flavonoids, alkaloids and polyphenols components. These chemicals function as antioxidants, effectively neutralising free radicals and providing protection against skin damage caused by UV radiation. The objective of this study was to ascertain the IC50 value of butterfly pea extract and thereafter to evaluate the degree of customer preference and convenience towards pharmaceutical items. This study utilised ultrasound-assisted extraction with a solvent technique employing 96% ethanol to generate extracts. These extracts were then compounded into several topical formulations including cream, gel and face spray. Initial assessments were conducted on all compositions, encompassing organoleptic, homogeneity, pH, viscosity, specific gravity, adhesion, spreadability, wetness and irritation. This study also incorporated acceptance and customer preference as factors. The antioxidant activity of BPF extract was determined using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) technique by estimating the IC50 value. The analysis revealed that the BPF extract had a yield of 38.75%. The IC50 values for the gel, cream and face mist preparations were 97.70, 49.14 and 73.89 ppm respectively. The cream recipe had the highest level of antioxidant activity. The determination of consumer preference has indicated that the majority of consumers favours face mist over other formulations.

Role of the structural order of the hydration layer in regulating the heterogeneous ice nucleation efficiency

Understanding the complex microscopic mechanisms of heterogeneous ice nucleation is crucial across diverse fields from cloud science to microbiology. In this work, we examined the ability of solid surfaces to promote ice nucleation as a function of the structural order of interfacial water, including the first and second hydration layers. Comprehensive all-atom molecular dynamics simulations using the TIP4P/ice water model were conducted on a water film atop a modeled surface inspired by the (0001) surface of AgI crystal, with varying surface charges. These simulations revealed non-monotonic nucleation rates. The first hydration layer formed a hexagonal hydrogen-bond network resembling ice structures, exhibiting low mobility essential for inducing ice nucleation. Notably, the second hydration layer, acting as a key-point bridge, displayed varying degrees of orientational preference facilitated by inter-layer hydrogen bonds. The calculation of fluctuation parameters indicated that the greater structural order of the second layer significantly enhances the surface’s ice-forming capabilities. Unlike previous studies that focused primarily on the role of the first layer of interfacial water, our findings demonstrate that the second layer provides a more accurate indicator of ice nucleation capabilities.

A novel fuzzy neural collaborative filtering for recommender systems

In collaborative filtering recommendations, part of studies mainly focus on quantitatively learning user preferences based on explicit rating information. However, due to the uncertainty and complexity of decision-making scenarios, user preferences usually express ambiguity and diversity. Therefore, to fully capture user preferences from both qualitative and quantitative perspectives and improve the accuracy and reliability of recommendations, we propose a novel fuzzy neural collaborative filtering for recommender systems. Firstly, we qualitatively divide user preferences into fine-grained categories based on picture fuzzy set and transform the rating matrix into four preference degree matrices. Then, we employ Bernoulli matrix factorization to independently learn preference features of each submatrix to obtain picture fuzzy numbers. To enhance the adaptability of picture fuzzy set in recommender systems, we design an improved scoring function based on picture fuzzy number to effectively distinguish differences in user preference levels. In addition, we use a simple deep neural framework to quantitatively extract global preferences of users and fuse it with fine-grained preferences of users to thoroughly predict user preferences. Experiments on four benchmark datasets show that the proposed model outperforms other comparison methods in terms of recommendation accuracy. Compared with the closest competitor method, our model has the highest improvements of 5.08% and 4.04% in the metrics HR@10 and NDCG@10, respectively.

Effect of the deposition sequence of Ti and W on the Ni-based Ohmic contacts to n-type 4H-SiC

The paper investigated the deposition sequence-dependent behavior of Ni (50 nm)/Ti (60 nm)/W (60 nm) and Ni (50 nm)/W (60 nm)/Ti (60 nm) Ohmic contacts on n-type 4H-SiC after annealing at 1050 °C for 3 min in Ar atmosphere by in-depth electrical and physical characterization. The contact resistivity of the Ni/Ti/W structure (∼ 8.43 × 10−6 Ω·cm2) was found to be lower than that of the Ni/W/Ti structure (∼ 21.9 × 10−6 Ω·cm2). For the Ni/W/Ti structure, the W layer closer to the contact interface led to an increase in the preferred orientation degree of the δ-Ni2Si (220) plane at the interface, favoring a lower contact resistivity according to previous studies. However, the content and interfacial coverage of δ-Ni2Si is reduced by the WxNiyC phase and the interfacial strain/stress is greatly increased by the WxNiyC phase as well, which ultimately leads to an increase in the contact resistivity. The larger interfacial strain/stress in the Ni/W/Ti structure also results in a rough surface morphology with more microcracks and a large area of delamination. In addition, the shearing strength of Al wire bonding points on the Ni/W/Ti surface is slightly weaker than that on the Ni/Ti/W surface due to the higher surface roughness. The above experimental findings can provide a guideline for further structural optimization of the 4H-SiC Ohmic contacts.

Mixed Methods Study Investigating Adolescent Acceptance and Implementation Outcomes of Serving Spicy Vegetables in School Lunch

BackgroundOnly a few adolescents are meeting their daily vegetable requirement. At the same time, spicy food is increasingly popular and familiar across cultures. ObjectivesTo explore the implementation of spicy vegetables into school meals, the primary objective is to determine adolescents’ preferred degree of hot spice on steamed broccoli. Secondary objectives include estimating the appropriateness and acceptability of spicy vegetables in the National School Lunch Program and identifying strategies to promote spicy vegetables within school meals. MethodsOne hundred participants between the age 11 and 17 y sampled 4 steamed broccoli florets with varying levels of a ground red and cayenne pepper spice blend (0, 0.9, 2.0, and 4.0 g). Participants rated their likeability of each broccoli sample on a 9-point hedonic scale and answered a survey assessing chili liking, chili consumption patterns, appropriateness, and acceptability. An interview assessed perspectives on spicy vegetables within school lunch.Regression analyses assessed relationships between participant attributes and sample ratings and survey outcomes. Agglomerative hierarchical cluster analysis was conducted to cluster together participants with similar sample liking ratings. ResultsSeventy-seven percent of participants reported that chili pepper makes food taste better, and 67% consumed spicy food weekly or daily. Chili likers (n = 41) were the dominant cluster group, compared with moderates (n = 31) and chili dislikers (n = 28). Thematic analysis results suggested that most participants support incorporating spicy vegetables into school lunch but mushy vegetable texture may undermine the impact of changing school vegetable spice levels. ConclusionsSpicy foods are commonly consumed by adolescents, and these findings support the inclusion of spicy vegetables in school lunch. Additional research is needed to identify policies and practices to improve the texture of vegetables in school meals and determine additional strategies to support cultural humility in child nutrition programs.

Rehabilitation in subjects with frozen shoulder: a survey of current (2023) clinical practice of Italian physiotherapists

ObjectiveFrozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions.AimThe aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature.MethodsA web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices.ResultsA total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients’ compliance with exercises at home and for motivational/educational purposes.Discussion and ConclusionThe clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

Influence of Hardwood Lignin Blending on the Electrical and Mechanical Properties of Cellulose Based Carbon Fibers.

Carbon fibers (CFs) are fabricated by blending hardwood kraft lignin (HKL) and cellulose. Various compositions of HKL and cellulose in blended solutions are air-gap spun in 1-ethyl-3-methylimidazolium acetate (EMIM OAc), resulting in the production of virtually bead-free quality fibers. The synthesized HKL-cellulose fibers are thermostabilized and carbonized to achieve CFs, and consequently their electrical and mechanical properties are evaluated. Remarkably, fibers with the highest lignin content (65%) exhibited an electrical conductivity of approximately 42 S/cm, surpassing that of cellulose (approximately 15 S/cm). Moreover, the same fibers demonstrated significantly improved tensile strength (∼312 MPa), showcasing a 5-fold increase compared to pure cellulose while maintaining lower stiffness. Comprehensive analyses, including Auger electron spectroscopy and wide-angle X-ray scattering, show a heterogeneous skin-core morphology in the fibers revealing a higher degree of preferred orientation of carbon components in the skin compared to the core. The incorporation of lignin in CFs leads to increased graphitization, enhanced tensile strength, and a unique skin-core structure, where the skin's graphitized cellulose and lignin contribute stiffness, while the predominantly lignin-rich core enhances carbon content, electrical conductivity, and strength.

Life-threatening airway obstruction by Riedel's thyroiditis: a rare presentation and diagnostic dilemma.

Riedel's thyroiditis is the rarest form of thyroiditis, occasionally resulting in rapid thyroid enlargement and potential tracheal obstruction. Here, we detail the case of an 81-year-old woman with a medical history including Hodgkin lymphoma, Hashimoto's thyroiditis, and multinodular goiter. She presented to the emergency room with stridor, cervical swelling, and breathing difficulties for over 2 days. CT scans revealed substantial thyroid enlargement causing significant glottal and tracheal compression, to a minimum tracheal diameter of 7 mm. Due to the severity of the compressive symptoms, orotracheal intubation and mechanical ventilation were deemed necessary. Surprisingly, despite the initial suspicion of malignancy given the rapid growth in the elderly, subsequent cytological and histological evaluations indicated a benign form of invasive fibrous thyroiditis - Riedel's thyroiditis. Although surgical intervention was advised, the patient declined and opted for endobronchial treatment with a prosthetic stent and subsequent treatment with systemic glucocorticoids. Following successful treatment, she was discharged within a week and resumed normal activities without respiratory distress. This case is noteworthy for its rapid benign mass growth, rare emergent presentation, and the patient's advanced age. The rapid enlargement of the thyroid gland in elderly patients poses a diagnostic challenge, stemming from the higher occurrence of aggressive thyroid carcinomas. Despite the clinical presentation, a comprehensive diagnostic workup, including fine-needle aspiration and core-needle biopsy, is crucial for accurately distinguishing between benign and malignant causes of thyroid nodule enlargement. This case report illustrates diverse treatment options for Riedel's thyroiditis, and the importance of individualized treatment plans based on the degree of airway obstruction, patient preferences, and response to initial interventions. Clinicians should contemplate the inclusion of glucocorticoids in the therapeutic regimen for Riedel's thyroiditis, particularly in cases where surgical intervention is not feasible or declined by the patient.

Research on the impact and heterogeneity of housing on the allocation of financial assets of households: Evidence from China

This paper investigates the impact of housing with both consumption and investment attributes on the risky financial asset allocation of households, constructs Probit and Tobit models using 2019 China Household Finance Survey (CHFS) data, and proceeds to the mediation effect test and heterogeneity analysis. Results indicate that owning only one house exhibits a crowding-out effect on the risky financial asset allocation of urban households, with the degree of risk preference as the mediating effect mechanism, while owning multiple houses exhibits an asset allocation effect. Housing borrowing other than bank loans inhibits urban households from making risky financial asset allocations. The effect of housing on risky financial asset allocation is heterogeneous by income, age, and region.

Preferences reveal dissociable encoding across prefrontal-limbic circuits.

Individual preferences for the flavor of different foods and fluids exert a strong influence on behavior. Most current theories posit that preferences are integrated with other state variables in the orbitofrontal cortex (OFC), which is thought to derive the relative subjective value of available options to guide choice behavior. Here, we report that instead of a single integrated valuation system in the OFC, another complementary one is centered in the ventrolateral prefrontal cortex (vlPFC) in macaques. Specifically, we found that the OFC and vlPFC preferentially represent outcome flavor and outcome probability, respectively, and that preferences are separately integrated into value representations in these areas. In addition, the vlPFC, but not the OFC, represented the probability of receiving the available outcome flavors separately, with the difference between these representations reflecting the degree of preference for each flavor. Thus, both the vlPFC and OFC exhibit dissociable but complementary representations of subjective value, both of which are necessary for decision-making.

The Impact of Herders’ Risk Attitudes on Livestock Insurance: Evidence from the Pastoral Areas of Tibetan Plateau

In the context of advancing the transformation and upgrading of grassland animal husbandry, encouraging and guiding the widespread adoption of livestock insurance plays an important role in promoting the sustainable development of the livestock industry. This paper explores the impact of herders’ attitudes and perceptions towards climate change risks on their livestock insurance strategies. Firstly, experimental economics methods are employed to measure the risk preferences of herders on the Tibetan Plateau. Secondly, a theoretical model incorporating risk preferences and insurance adoption behavior is constructed. Finally, the effects of herders’ risk preferences on insurance adoption behavior are empirically examined through double-hurdle models, instrumental variable models, and moderating effect models. The results reveal that (1) most herders on the Tibetan Plateau exhibit risk-averse characteristics. (2) The degree of risk preference has a significant negative impact on herders’ insurance adoption behavior, while the risk perception significantly positively influences insurance adoption. The results remain valid even after addressing issues of endogeneity and conducting robustness checks. (3) Livestock income plays a crucial moderating role in the mechanism through which risk attitudes affect insurance adoption behavior. (4) The impact of risk preference on insurance adoption behavior shows regional and income heterogeneity.

Complete chloroplast genomes and phylogenetic relationships of Pedicularis chinensis and Pedicularis kansuensis

The complete cp genomes of Pedicularis chinensis (GenBank accession number: OQ587614) and Pedicularis kansuensis (GenBank accession number: OQ587613) were sequenced, assembled, and annotated. Their chloroplast (cp) genome lengths were 146,452 bp, and 146,852 bp, respectively; 120 and 116 genes were identified, comprising 75 and 72 protein-coding genes (PCGs), 37 and 36 transfer RNA (tRNA) genes, and 8 and 8 ribosomal RNA (rRNA) genes, for P. chinensis and P. kansuensis, respectively. A simple sequence repeat (SSR) analysis revealed that the repetitive sequences were mainly composed of mononucleotide repeats (A/T motif) and dinucleotide repeats (AT/TA motif). Comparative genomics identified several variant genes (rpl22, rps19, rpl12, ycf1, trnH, psbA, and ndhH) and variant regions (trnS-GGA, trnV-UAC, ndhJ-trnV, ycf4-cemA, ndhE-nhdG, and rpl32-trnL) with a high Pi, indicating the potential to serve as deoxyribo nucleic acid (DNA) barcodes for Pedicularis species identification. The results show that the cp genomes of P. chinensis and P. kansuensis were the same as those of other plants in Pedicularis, with different degrees of AT preference for codons. Large differences in the number of SSRs and the expansion of the inverted repeat (IR) region showed strong variability and interspecific differentiation between these two species and other species represented in the genus Pedicularis. A phylogenetic analysis showed that P. kansuensis had the closest relationship with P. oliveriana, and P. chinensis had the closest relationship with P. aschistorhyncha. These results will facilitate the study of the phylogenetic classification and interspecific evolution of Pedicularis plants.

Structurally unjust: how lay beliefs about racism relate to responses to racial inequality in the criminal legal system

Racial inequality has been a persistent component of American society since its inception. The present research investigates how lay beliefs about the nature of racism—as primarily caused by prejudiced individuals or, rather, to structural factors (i.e., policies, institutional practices) that disadvantage members of marginalized racial groups—predict reactions to evidence of racial inequality in the criminal legal system (Studies 1–3). Specifically, the current research suggests that holding a more structural (vs. interpersonal) view of racism predicts a greater tendency to perceive racial inequality in criminal legal outcomes. Moreover, White Americans' lay beliefs regarding racism, coupled with their general degree of preference for societal hierarchy, predict support for policies that would impact disparities in the U.S. prison population. Together, this work suggests that an appreciation of structural racism plays an important role in how people perceive and respond to racial inequality.

Effects of Implicit Racial Bias and Standardized Patient Race on Genetic Counseling Students’ Patient-Centered Communication

ABSTRACT Clinician racial bias has been associated with less patient-centered communication, but little is known about how it affects trainees’ communication. We investigated genetic counseling students’ communication during sessions with Black or White standardized patients (SPs) and the extent to which communication was associated with SP race or student scores on the Race Implicit Association Test (IAT). Sixty students conducted a baseline SP session and up to two follow-up sessions. Students were randomly assigned to a different White or Black SP and one of three clinical scenarios for each session. Fifty-six students completed the IAT. Session recordings were coded using the Roter Interaction Analysis System. Linear regression models assessed the effects of IAT score and SP race on a variety of patient-centered communication indicators. Random intercept models assessed the within-student effects of SP race on communication outcomes during the baseline session and in follow-up sessions (n = 138). Students were predominantly White (71%). Forty students (71%) had IAT scores indicating some degree of pro-White implicit preference. Baseline sessions with White relative to Black SPs had higher patient-centeredness scores. Within-participant analyses indicate that students used a higher proportion of back-channels (a facilitative behavior that cues interest and encouragement) and conducted longer sessions with White relative to Black SPs. Students’ stronger pro-White IAT scores were associated with using fewer other facilitative statements during sessions with White relative to Black SPs. Different patterns of communication associated with SP race and student IAT scores were found for students than those found in prior studies with experienced clinicians.
